Abstract: Embodiments herein provide for the usage of exceptional resource pool for positioning (RP-P) when a UE transmits or receives RF signals for positioning via sidelink. The UE can determine whether one or more conditions have been met for using the exceptional RP-P during a positioning session, then transmit or receive the one or more reference signals accordingly. Various conditions may be established for using the exceptional RP-P, including radio link failure, high-priority/emergency conditions, a number of anchor UEs in non-exceptional RP-P being below a threshold, a number of anchor UEs in the exceptional RP-P being above the threshold, and others. The exceptional RP-P may be provided to the UE via an exceptional RP-P configuration from a base station, location server, or another UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in an unlicensed spectrum (e.g., a shared radio frequency spectrum band). As such, the UE may determine a codebook size for transmitting hybrid access request (HARQ) acknowledgement (ACK) feedback with respect to the unlicensed spectrum. Accordingly, the UE may base the HARQ ACK codebook size on a number of HARQ processes with which the UE has been configured. Additionally or alternatively, the UE may base the HARQ ACK codebook size on a number and/or duration of downlink channel monitoring occasions indicated by the base station. In some cases, the UE may base the HARQ ACK codebook size on a combination of the techniques described herein.

Abstract: Aspects presented herein may enable a network node (e.g., a UE, a TRP/base station) to provide its beam squint information and/or to receive beam squint information of another positioning entity to improve the accuracy and reliability of UE positioning. In one aspect, a network node obtains beam squint information associated with a set of beams of the network node under a plurality of center frequencies. The network node transmits, for a network entity, the beam squint information for at least one beam of the set of beams for a positioning session. The network entity participates, based on the beam squint information via the at least one beam, in the positioning session with the network entity.
