COLLISION HANDLING BETWEEN SCHEDULING REQUESTS AND HYBRID AUTOMATIC REPEAT REQUEST ACKNOWLEDGMENT FEEDBACK HAVING DIFFERENT PRIORITIES
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a collision between one or more hybrid automatic repeat request (HARQ) acknowledgment (ACK) resources and one or more scheduling request (SR) resources having different priorities. The UE may perform an action associated with at least one of the one or more HARQ ACK resources or the one or more SR resources, wherein the action is based at least in part on at least one of: a physical uplink control channel (PUCCH) format or a priority associated with a HARQ ACK resource, or a PUCCH format or a priority associated with an SR resource. Numerous other aspects are provided.
METHOD AND APPARATUS FOR INTER-USER EQUIPMENT COORDINATION SIGNALING
Methods and apparatuses for inter user equipment (UE) coordination signaling. A method of operating a UE includes determining a first set of first sidelink (SL) resources based on SL sensing and resource exclusion; selecting a first one or more SL resources within the first determined set for reservation, transmitting information about the first one or more SL resources, and receiving inter UE co-ordination information indicating whether a SL resource in the first one or more SL resources has a conflict. The method further includes transmitting on one of the first one or more SL resources, when the one SL resource does not have a conflict; and determining a second set of SL resources based on SL sensing and resource exclusion, and selecting a second one or more SL resources within the second set for transmission and reservation, when all of the first one or more SL resources have a conflict.
BACKHAUL RADIO WITH ADVANCED ERROR RECOVERY
A backhaul radio is disclosed that operates in multipath propagation environments such as obstructed LOS conditions with uncoordinated interference sources in the same operating band. Such a backhaul radio may use an advanced ARQ protocol, which uses an ACK_MAP, constructed by a combination of implicit and explicit signaling, and performs a combination of proactive and reactive retransmissions.
TECHNIQUES FOR A DELAY-IMPOSED HARQ-ACK/NACK REPORTING
Aspects of the present disclosure provide techniques to expedite transmissions of hybrid automatic repeat request (HARQ) acknowledgment or negative acknowledgment (ACK/NACK) feedbacks based on delay constraints associated with at least semi-persistent scheduling (SPS) downlink packets received at the user equipment (UE). Specifically, in accordance with aspects of the present disclosure, each of the one or more SPS PDSCH configurations may be associated with a delay parameter that identifies the maximum amount of time or slots that the UE can wait prior to transmitting the HARQ-ACK/NACK feedback associated with the PDSCH received at the UE.
Systems and methods for improved uplink coverage
Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.
Data transmission method and apparatus
Embodiments of the present disclosure disclose a data transmission method and apparatus. The data transmission method includes: performing, by a Packet Data Convergence Protocol (PDCP) entity, lossless transmission on PDCP protocol data units (PDUs) or PDCP service data units (SDUs), where each of the PDCP PDUs or the SDUs is associated with one serial number. In this embodiment, during lossless transmission, no data packet is lost, thereby ensuring communication quality in an inter-station carrier aggregation scenario and achieving an optimization objective.
METHOD FOR COLLECTING DATA IN A NETWORK, SENSOR, CONSUMPTION METER, DATA COLLECTOR AND NETWORK
A method collects data in a network by operation of a local sensor of a consumption meter where the network is part of a supply network. The network distributes a consumable good. The sensor has a measuring element providing raw measurement data corresponding to a physical or physicochemical value or parameter. The sensor has a wired and/or radio communication device and a memory. For the determination of the measurement resolution of the sensor the conditions for generating time stampings using a correlation model are determined in advance, on the basis of the correlation model time stampings of successive raw measurement data in the sensor are generated. The time stampings are transmitted over a wired connection and/or a radio link so that on the basis of the time stampings using the correlation model the raw measurement data collected by the measuring element are reconstructed and evaluated and used for network monitoring.
CHANNEL DISRUPTION WIRELESS COMMUNICATION SYSTEM
The wireless channel of the wireless communication system is selectively disrupted or interfered with based on the logical states of the data to be transmitted by an electronic device having no wireless data signal transmitting circuitry. A host device transmits a query packet which includes a header and a series of sub-frames to be received by a receiving device. As each sub-frame is transmitted, the electronic device can selectively disrupt the wireless channel by changing its characteristics such that the receiving device can no longer decode that sub-frame based on channel estimation from the header of the frame. Wireless channel disruption occurs in response to a specific state of the bit of data of a message to be communicated by the electronic device. The receiving device then issues a status reply to the host device indicating which sub-frames are decodable and which sub-frames are undecodable based on the initial channel estimation. The host device decodes the status reply to extract the message.
Methods for enabling delay-awareness in the constrained application protocol (CoAP)
A Delay Indicator parameter is contained in CoAP messages to reflect delay tolerance information. The Delay Indicator is leveraged by CoAP Clients and CoAP Servers to improve their behavior such as entering sleep mode to save energy while not violating delay requirements. A timeout mechanism for CoAP Response is enabled by a RESPONSE_Timer based on the Delay Indicator in CoAP ACK. Cancellation of CoAP Requests is enabled by leveraging the delay tolerance information as indicated by Delay Indicator.
Simultaneous bandwidth parts switching
A wireless device receives one or more first radio resource control (RRC) messages. The first RRC messages comprise one or more configuration parameters of a first cell and a second cell. A second RRC message is received. The second RRC message indicates a first change of a first active bandwidth part (BWP) of the first cell. Processing of the second RRC message is completed. A determination is made that the completing occurs during a time duration of a second change of a second active BWP of the second cell. Based on the determining, the first change of the first active BWP is delayed until the second change of the second active BWP is completed.
