Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a sidelink communication. The UE may generate a transmit power control command based at least in part on a measurement of the sidelink communication. The UE may transmit, via a sidelink feedback channel, the transmit power control command to control a transmit power, for another sidelink communication, of the source UE. Numerous other aspects are provided.

In some aspects, a user equipment (UE) may receive, during an accumulation period, a plurality of transmit power control (TPC) commands that are based at least in part on one or more sidelink communications transmitted by the UE. The UE may determine a transmit power adjustment for the UE based at least in part on the plurality of TPC commands. The UE may selectively adjust a transmit power of the UE based at least in part on the transmit power adjustment. Numerous other aspects are provided.

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: 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: Certain aspects of the present disclosure provide methods and apparatus for selecting numerology for sidelink synchronization signals. When one or more user equipment (UE) are in various modes of network signaling with a base station (BS), a first UE may determine a mode of network signaling between the first UE and the BS. The UE may then determine a first numerology based on the mode, and receive, from a second UE, a sidelink signal having a subcarrier spacing corresponding to the first numerology.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation and other clean-slate, OFDM based systems such as enhanced component carrier (eCC) systems. An example method is provided for operations which may be performed by a BS to generate and transmit a dual-layer PSS, and correspondingly, techniques for a UE to detect the dual-layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to a number of symbols within one or more subframes of a frame.

Abstract: The present disclosure relates to transmitting and receiving improved monitoring reports. A base station can configure a user equipment (UE) to monitor a channel/signal on multiple beams. The base station can transmit the multiple beams to the UE, which are at different time periods in a monitoring window. The UE can then monitor the multiple beams within the monitoring window and determine a monitoring report. The UE can then transmit the monitoring report to the base station, wherein the monitoring report indicates a subset of multiple beams as being more or less suitable for communication. The base station can also indicate that it will stop transmitting one or more beams and then stop transmitting the beams. If the UE does not send the report, the base station can continue to transmit the multiple beams.

The example method generally comprises determining a number of pilot symbols to transmit for one or more slots of a first subframe based, at least in part, on a coverage enhancement (CE) level, and transmitting at least one uplink data channel having the determined number of pilot symbols in the one or more slots of the first subframe.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.
