Method and device for performing communication
Embodiments of the disclosure provide a method and device for performing communication. The method comprises: determining a target transmission pattern from a set of candidate transmission patterns, wherein each of the candidate transmission patterns contains a DL transmission part and/or a UL transmission part, and the candidate transmission patterns differ from one another in terms of subcarrier spaces of the respective DL transmission parts and/or the UL transmission parts; and performing communication between a network device and a terminal device by using the target transmission pattern.
Determining an association between DMRS and PTRS
Apparatuses, methods, and systems are disclosed for determining an association between DMRS and PTRS. One apparatus (200) includes a processor (202) that: determines (1402) a scheduled physical resource block position and bandwidth; and determines (1404), based on the scheduled physical resource block position and bandwidth, an associated demodulation reference signal port index within the physical resource block for a phase tracking reference signal.
Method and an apparatus for determining a local frequency in wireless communication system
The disclosure relates to a communication scheme and system for converging a 5.sup.th generation (5G) communication system for supporting a data rate higher than that of a 4.sup.th generation (4G) system with an internet of things (IoT) technology. The disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. A method for determining a local frequency in a wireless communication system includes identifying frequency bands in use for communication, identifying, based on a first frequency band being in use for communication, a first subcarrier located at the center of the first frequency band among multiple subcarriers constituting the first frequency band, and determining a frequency between the first subcarrier and a second subcarrier closest to the first subcarrier as the local frequency.
Techniques for configuring search spaces in multicast/broadcast service (MBS) wireless communications
Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.
Expediting sensor reporting in a time division multiple access shared-medium network
Various arrangements for expediting sensor reporting in a wireless hybrid time division multiple access (TDMA) shared-medium network are presented. A TDMA channel allocation process for the wireless hybrid TDMA shared-medium network may be performed such that each sensor device of a plurality of sensor devices is assigned a different timeslot. Within each timeslot of the plurality of timeslots, a grant-free transmission window may be reserved. Any sensor device may be permitted to transmit data during any grant-free transmission window. In response to the sensor device determining the sensor data is to be transmitted, the sensor device may transmit a message indicative of the sensor data during a grant-free transmission window of a timeslot assigned to a different sensor device.
Techniques for configuring search spaces for sidelink communication
Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs). Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) to decode the sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) transmitted between a first UE and a second UE over sidelink communication without the need for the receiver UE (e.g., second UE) to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications.
Resource Scheduling Method, Apparatus, and Device
Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).
Determining whether a wireless communication medium is idle
A first wireless communication device receives a packet from a second wireless communication device, the packet having information indicating that the second wireless communication device is relinquishing control of a wireless communication medium. The first wireless communication device determines whether the packet was transmitted in a wireless network to which the first wireless communication device belongs, and determines whether a network allocation vector (NAV) timer of the first wireless communication device was most recently set in connection with a transmission from the wireless network to which the first wireless communication device belongs. When i) the packet was transmitted in the wireless network to which the first wireless communication device belongs, and ii) the NAV timer was most recently set in connection with a transmission from another wireless network to which the first wireless communication device does not belong, the NAV timer is not reset.
METHOD AND APPARATUS FOR RECEIVING OR TRANSMITTING DOWNLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM
According to one embodiment of the present invention, a method of decoding, by a user equipment, a downlink signal in a wireless communication system comprises the steps of: receiving a semi-persistent zero power-channel state information reference signal (SP ZP CSI-RS) resource configuration from a base station; and decoding a downlink signal according to the SP ZP CSI-RS resource configuration. The SP ZP CSI-RS resource configuration includes a plurality of SP ZP CSI-RS resources and information on whether or not each of a plurality of the SP ZP CSI-RS resources is used can be indicated or configured by the base station.
PUNCTURING UNIT FOR SOUNDING REFERENCE SIGNAL (SRS) COMB PATTERNS WITH CYCLIC SHIFTING
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.
