摘要： The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method for operating a terminal is provided. The method includes detecting, scheduling assignment (SA) of another terminal in a sensing window based on transmission time intervals (TTIs) with different lengths in a resource pool; detecting a receiving power of a scheduled data channel based on the SA and a receiving energy of each sub-channel of each subframe; determining resources for data transmission based on the SA, the receiving power and the receiving energy; and transmitting data on the resources.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

摘要： Aspects described herein relate to bi-direction preemption indication transmissions. In one example, a node such as an integrated access and backhaul (IAB) node may determine that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and transmit, to a user equipment (UE), the bi-direction preemption indication indicating that the set of one or more resources are preempted for use for both of the uplink transmission and the downlink transmission. In another example, a UE may receive a bi-direction preemption indication indicating that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and perform rate matching for both of the uplink transmission and downlink transmission based on the set of one or more resources indicated by the bi-direction preemption indication.

摘要： A method and apparatus of a user equipment (UE) in a wireless communication system are provided. The method and apparatus comprise: receiving a set of higher layer parameters including configuration information for sidelink synchronization signals and physical sidelink broadcast channel (S-SS/PSBCH) block; determining, based on the configuration information for the S-SS/PSBCH block, a number of transmitted S-SS/PSBCH blocks (NSSB), an offset for transmitted S-SS/PSBCH blocks (OSSB), and an interval for transmitted S-SS/PSBCH blocks (DSSB); and determining a set of slots containing the transmitted S-SS/PSBCH blocks within a period for a transmission of the S-SS/PSBCH block, wherein an index of a slot in the set of slots is determined based on OSSB+ISSB*DSSB, where ISSB is an index of the S-SS/PSBCH block with 0≤ISSB≤NSSB−1.

摘要： Technology for an eNodeB to communicate with a user equipment (UE) using a self-contained time division duplex (TDD) subframe within a wireless communication network is disclosed. The eNodeB can process, for transmission to the UE, a DL self-contained time division duplex (TDD) subframe comprising an extended physical downlink shared channel (xPDSCH), an extended physical downlink control channel (xPDCCH), a downlink (DL) spacing signal, and a guard period, wherein the xPDSCH, the xPDCCH, the DL spacing signal, and the guard time are located within the DL self-contained TDD subframe prior to an extended physical uplink control channel (xPUCCH). The eNodeB can process, an uplink (UL) self-contained TDD subframe, received from the UE, having a UL spacing signal located after an extended physical uplink shared channel (xPUSCH).

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first cell, downlink control information for physical downlink control channel ordered contention-free random access, wherein the downlink control information indicates a timing advance group of a second cell and one or more parameters associated with a random access message to be transmitted by the UE via the second cell, wherein the first cell and the second cell belong to different timing advance groups. The UE may transmit the random access message via the second cell according to the one or more parameters and a timing advance value determined based at least in part on the timing advance group of the second cell. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.
