Abstract: In an embodiment, a UE identifies a pool of resources where transmission of sidelink synchronization signals is permitted, the pool of resources comprising at least UE-specific resources, and transmits a sidelink synchronization signal to one or more peer sidelink UEs based on a subset of the pool of resources. In another embodiment, a UE transmits a synchronization request message to at least one peer sidelink UE, and receives at least one sidelink synchronization signal from the at least one peer sidelink UE in response to the transmitting.

Abstract: Certain aspects of the present disclosure provide techniques for providing channel state information associated with sidelink air interfaces. A method that may be performed by a first wireless node (e.g., a user equipment) includes receiving, from a base station, a reference signal (RS) configuration indicating one or more sidelink resource sets and transmitting, to one or more second wireless nodes, one or more sidelink reference signals based at least in part on the RS configuration. The method also includes receiving one or more feedback reports from the one or more second wireless nodes, wherein each of the feedback reports includes an ordered sequence of at least one parameter associated with a sidelink channel quality of the sidelink reference signals. The method further includes forwarding the one or more feedback reports to the base station.

Abstract: According to an example, a method of wireless communication comprises receiving a group wake-up signal configuration corresponding to a group of UEs that share a wake-up signal associated with a discontinuous reception operation, wherein the group wake-up signal configuration identifies a set of wake-up parameters for at least one of the wake-up signal or the discontinuous reception operation. The method further includes transmitting a wake-up configuration update triggering message, receiving a group wake-up signal configuration update message including at least one new wake-up parameter, and performing the discontinuous reception operation based on the at least one new wake-up parameter. A corresponding method of wireless communication at a base station is also described.

Abstract: Certain aspects of the present disclosure provide techniques for reducing overhead for channel state information (CSI). Certain aspects provide a method for wireless communication. The method generally includes receiving a channel state information reference signal (CSI-RS), determining one or more feedback components associated with a CSI feedback type based on the CSI-RS, identifying that a payload of the one or more feedback components is to be compressed, compressing the payload, and reporting the compressed payload.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a collision between an access link communication and a sidelink communication. The UE may resolve the conflict based at least in part on a priority associated with the access link communication and a priority associated with the sidelink communication. Numerous other aspects are provided.

Abstract: Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, a total bandwidth may be divided into a plurality of bandwidth parts (BWPs), each including a plurality of tones. Each of the BWPs may further be divided into two or more interlaces, where each interlace includes a respective number of interleaved tones. A base station may assign each of a plurality of UEs a respective set of one or more interlaces within at least one BWP for multiplexing communication with the base station.

Abstract: Aspects described herein relate to determining symbols over which to transmit repetitions for certain types of communications. A resource grant can include information for transmitting a number of repetitions over a collection of resources, such as a starting symbol over which to transmit communications, a number of symbols over which to transmit communications, and/or a nominal number of repetitions to transmit. Where time division multiplexing (TDM) communications are configured, a slot format indicator (SFI) can be semi-statically or dynamically configured and can indicate a communication direction of symbols within one or more slots as being uplink, downlink, or flexible. Thus, mapping uplink communications to the symbols may be based on additional considerations.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: A method and apparatus for enabling repetitive transmissions for low latency systems is disclosed. For example, a base station may determine whether an uplink coverage parameter for a UE communicating with the network entity on an uplink communication channel satisfies an uplink coverage threshold, and transmit an activation message for repetition-based uplink communications to the UE based on a determination that the uplink coverage parameter for the UE communicating with the network entity on the uplink communication channel satisfies the uplink coverage threshold. Further, a UE may receive an activation message for repetition-based uplink communications from a network entity, and perform repetitive transmissions on the uplink communication channel for the duration indicated by the one or more transmission parameters in the activation message, the repetitive transmissions being configured based on the uplink sTTI pattern.
