摘要： Wireless communication techniques leveraging DMRS sharing patterns are disclosed. A method of wireless communication includes receiving, by a user equipment (UE) device, control information. The control information indicates mapping of uplink transmission parameters to one or more demodulation reference signal (DMRS) sharing patterns. The method further includes sending an uplink transmission to a base station in accordance with a DMRS sharing pattern. The DMRS sharing pattern is selected from among the one or more DMRS sharing patterns based on one or more parameters of the uplink transmission. Other aspects and features are also claimed and described.

摘要： Methods, systems, and devices for wireless communications are described. A first device (e.g., a relay user equipment (UE)) may establish a communication link, where the communication includes establishing a communication link between a second device (e.g., a remote UE) and a base station, the communication link including a first communication link between the second device and the first device and a second communication link between the first device and the base station. The first device may receive, over the first communication link, a transmission corresponding to data stored at the second device. The first device may receive, over the second communication link, an indication of one or more resources for a relay transmission corresponding to the data stored at the second device. The first device may transmit, over the second communication link, the relay transmission over the one or more resources based on receiving the sidelink transmission.

摘要： Methods, systems, and devices for wireless communications are described. A base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

摘要： Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

摘要： Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

摘要： Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive, via a first control resource set (CORESET) of a plurality of CORESETs monitored by the UE, a first downlink grant that schedules a downlink data transmission to the UE. The UE may receive the downlink data transmission from a first transmission reception point (TRP) of a plurality of TRPs and transmit feedback information for the downlink data transmission to the first TRP based at least in part on the first TRP being associated with the first CORESET or the first downlink grant being received via the first CORESET.

摘要： Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may use multiple antenna ports to communicate with multiple transmission/reception points (TRPs), and each antenna port may correspond to a spatial dimension along which wireless communications may be transmitted. The UE may transmit a first sounding reference signal (SRS) to a serving TRP to aid the serving TRP in determining a subset of spatial dimensions available to the UE along which to transmit downlink transmissions. Upon receiving a downlink transmission from the serving TRP along the subset of spatial dimensions as determined by the serving TRP, the UE may transmit a second SRS to a neighboring TRP to indicate the subset of spatial dimensions. The neighboring TRP avoid transmitting downlink transmissions to the UE or to other UEs along the subset of spatial dimensions, thereby mitigating interference along the subset of spatial dimensions.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

摘要： During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

摘要： Aspects described herein relate to providing demodulation reference signal (DMRS) transmissions for channel transmission repetitions. This can include defining DMRS patterns for channel transmission repetitions having a symbol length that is less than a threshold, dropping or deferring channel transmission repetitions that are mapped to a set of uplink symbols that are less than a threshold symbol length, and/or the like.
