Abstract: Techniques for a high-accuracy determination the position of a light user equipment (UE) using a single base station are presented. This is accomplished by leveraging communications with a premium UE having a known location relative to the base station. Wireless reference signals measured by the light UE and premium UE, along with a reference signal from the light UE to the premium UE, can be used to determine the position of the light UE geometrically. The determination can be made by the light UE, premium UE, or a location server, depending on desired functionality.

Abstract: A configuration to determine a starting bit for PUSCH repetition with TBS scaling. The apparatus determines a TBS of a PUSCH transmission based at least in part on a set of PUSCH resources corresponding to a set of PUSCH repetitions for transmission over a repetition unit comprising a plurality of slots. The apparatus determines a starting bit location of each code block of the PUSCH transmission for a first slot of the plurality of slots. The apparatus determines a different starting bit location of each code block of the PUSCH transmission for each slot of the plurality of slots following the first slot, wherein each of the different starting bit locations for each slot following the first slot is based on a two level RV cycling. The apparatus transmits the PUSCH repetitions, each slot comprising encoded data based on respective starting bit locations.

Abstract: A UE may receive a configuration of multiple TCI states including a TCI state for each of multiple TRPs. The UE may also receive an indication of dormancy for one or more TRP of the multiple TRPs. The UE may further transmit or receive communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP. The UE may communicate with a network entity that configures multiple TCI states for the UE. The multiple TCI states may include a TCI state for each of multiple TRPs. The network entity may output for transmission an indication of dormancy for one or more TRP of the multiple TRPs. The network entity may further output or obtain communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP.

Abstract: Disclosed are various techniques for wireless communication. In some aspects, a method of wireless communication performed by a user equipment (UE) includes determining a positioning reference signal (PRS) to random access channel (RACH) occasion (RO) mapping that defines specific ROs during which the UE should at least transmit a RACH sequence based on specific PRS measurements. The method also includes performing at least one PRS measurement. The method also includes transmitting a RACH sequence on at least one RO according to the PRS to RO mapping and based on the specific PRS measurement. The method optionally includes reporting a result of the PRS measurement to the base station according to the PRS to RO mapping based on the PRS measurements.

Abstract: A base station may transmit, to a user equipment (UE), an instruction for scheduling a physical uplink shared channel (PUSCH) transmission. The PUSCH transmission may be overlapping with at least one of a slot boundary or a symbol that is configured invalid for a PUSCH by the base station, and the UE may configure a first partial PUSCH and a second partial PUSCH, the second partial PUSCH being a subset of the PUSCH transmission and including a single symbol length. The UE may schedule the second partial PUSCH based on the instruction received from the base station.

Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.
