Beamforming enhancement via strategic resource utilization
The present disclosure describes methods and apparatuses for beamforming enhancement via strategic resource utilization. In some aspects, an air interface resource is used for exchanging wireless communications using one or more signal beams. In some implementations, end-user devices are classified into a beamforming state—such as active, idle, or inactive—based on an activity level with a base station. To facilitate antenna beamforming between the base station and an end-user device, opportunities for beamforming training are provided by strategically granting resource units based on one or more resource allocation rules. For example, both control and data information can be allocated together on the same frequencies for each end-user device. Also, an uplink or a downlink grant can be provided that precedes a downlink or an uplink allocation, respectively. In some implementations, the resource allocation rules are applied based on the beamforming state to which an end-user device has been classified.
Method and Apparatus for Low Latency Transmissions
A method and apparatus provide for low latency transmissions. A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be for a low latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A regular latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The regular latency transmission can have a longer latency than the low latency transmission.
Systems and methods for requesting duty cycle based channel access priorities
A client station includes a physical layer device to receive, from an access point, a requirement for assignment to a first power category among a plurality of power categories defined by the access point. Each of the plurality of power categories has a respective access priority associated with access to a communication channel. A request module is to determine whether an operating characteristic of the client station meets the requirement for assignment to the first power category and generate, in response to a determination that the operating characteristic meets the requirement, a request to be assigned to the first power category by the access point. The physical layer device is further to transmit the request to the access point and, based on whether the access point accepts or rejects the request, selectively access the communication channel according to a first access priority associated with the first power category.
LOGICAL CHANNEL PRIORITIZATION PROCEDURE FOR SIDELINK LOGICAL CHANNELS
The present disclosure relates to a method to be performed at a user equipment and to a user equipment operable in a wireless communications system supporting direct communication between user equipments. Accordingly, a sidelink configuration is stored in the user equipment, 5 specifying a plurality of destination groups, each destination group including possible destinations for sidelink data as well a logical channel priority is stored for each logical channel out of logical channels configured for the sidelink destination groups. The terminal then selects a sidelink destination group with a sidelink logical channel having sidelink data available for transmission with the 10 highest logical channel priority among the sidelink logical channels having data available for transmission, and allocates radio resources to the sidelink logical channels belonging to the selected sidelink destination group in decreasing priority order.
CARRIER PRIORITIZATION FOR TUNE-AWAY
Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.
Configurable groups of control channel resource sets for wireless communication
The described technology is generally directed towards wireless communications systems in which multiple control channel resource sets (CORESETs) are configured into a CORESET group. The CORESET group may be associated with a usage scenario/quality of service requirement, and used by user equipment to decode downlink control information corresponding to that usage scenario. For example, one CORESET group can be used for URLLC traffic, another for eMBB type traffic and another for mMTC traffic. Different CORESET groups may be used to provide different aggregation level sets, different DMRS pattern configurations, different search spaces, different transmission protocols/schemes, different beam management and recovery procedures, different radio link monitoring and radio link failure procedures, and so on. Different CORESET groups may be associated with different transmission points.
METHOD AND APPARATUS FOR LOW LATENCY TRANSMISSIONS
A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be used for a second latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A first latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The first latency transmission can have a longer latency than the second latency transmission.
Communication method and communications apparatus
This application discloses a communication method and a communications apparatus. The method implemented by a terminal includes: determining a configuration mode of one or more pilots used for K repeated transmissions, where in a first configuration mode, the terminal device sends a same pilot in each of first N of the K repeated transmissions, and does not send a pilot in remaining K−N transmissions; in a second configuration mode, the terminal device sends a first pilot in first N of the K repeated transmissions, and sends a second pilot in the remaining K−N transmissions; and in the third configuration mode, the terminal device sends the first pilot in each transmission in a first round of K transmissions, and sends the second pilot in each transmission in a second round of K transmissions; and sending the pilots based on the determined configuration mode when performing the K repeated transmissions.
MITIGATION OF INTER-BAND INTERFERENCE TO RECEIVERS BY ALLOCATING ALERTS IN FREQUENCY DOMAIN BASED ON SEVERITY
A transmitting device may select frequency domain resources for an alert transmission based on a severity level of the alert transmission. The transmitting device may determine a severity level of an alert transmission to be transmitted on one or more available channels. The transmitting device may determine a presence of one or more systems configured to transmit on one or more neighbor channels of the one or more available channels. The transmitting device may select, for the alert transmission, frequency domain resources within the one or more available channels based on the presence of the one or more systems and the severity level. The frequency domain resources for a highest severity level transmission are spaced further apart from the one or more neighbor channels in the frequency domain than resources for a lower severity level transmission. The transmitting device may transmit the alert transmission on the frequency domain resources.
METHODS AND APPARATUS TO FACILITATE DUPLEX MODE PER UPLINK CONTROL CHANNEL RESOURCE
Apparatus, methods, and computer-readable media for facilitating duplex mode per uplink control channel resource are disclosed herein. An example method for wireless communication at a user equipment includes receiving a physical uplink control channel (PUCCH) resource configuration from a base station, the PUCCH resource configuration indicating an uplink beam for transmitting an uplink transmission. The example method also includes identifying a downlink beam paired with the uplink beam for transmitting the uplink transmission, the paired downlink beam for full-duplex reception of a downlink transmission from the base station that overlaps in time with transmission of the uplink transmission. Additionally, the example method includes performing full-duplex communication with the base station by transmitting the uplink transmission using the uplink beam while receiving the downlink transmission using the paired downlink beam.
