Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, SPS via RRC signaling. The apparatus may also determine a UE Rx-Tx time difference, the UE Rx-Tx time difference being equal to a difference between a downlink subframe reception time and an uplink subframe transmission time. The apparatus may also transmit, to the base station, the UE Rx-Tx time difference or receive, from the base station, a base station Rx-Tx time difference, the base station Rx-Tx time difference being equal to a difference between an uplink subframe reception time and a downlink subframe transmission time.

Abstract: Wireless communication systems and methods related to channel occupancy time (COT) sharing when operating in a frame-based-equipment (FBE) mode over a shared frequency band are provided. In one aspect, a user equipment (UE) contends for a channel occupancy time (COT) in a first frame-based equipment (FBE) frame. The UE transmits, to a base station (B S), an uplink communication signal during a first portion of the COT. The UE receives, from the BS based on COT sharing information, a downlink communication signal during a second portion of the COT, wherein the second portion is non-overlapping with the first portion

Abstract: Aspects of the present disclosure provide techniques for handling scenarios where a physical uplink shared channel (PUSCH) repetition is scheduled as a single symbol. According to certain aspects, a user equipment (UE) is configured to detect that a nominal physical uplink shared channel (PUSCH) repetition is to be segmented into one or more actual PUSCH repetitions that include a single symbol actual PUSCH repetition and take one or more actions to handle a symbol length gap in transmission due to the single symbol actual PUSCH repetition.

Abstract: A method of wireless communication performed by a user equipment (UE) incudes receiving supplemental semi-persistent scheduling (SPS) via radio resource control (RRC) signaling. The method also includes receiving the downlink re-transmissions according to the supplemental SPS. A method performed by the UE also includes receiving downlink feedback information (DFI) for a packet and determining one or more of resource block allocation, a start and length indicator value (SLIV), or a number of repetitions for re-transmission of the packet in response to the DFI. The method further includes re-transmitting the packet during a re-transmission period based on one or more of the resource block allocation, the SLIV, or the number repetition.

Abstract: In an aspect, a UE and BS communicate data traffic in accordance with a first bandwidth part (BWP) configuration. The BS sends, to the UE in association with communication of a plurality of reference signals for positioning (e.g., PRS, SRS-P, etc.), an indication of a second BWP configuration that includes a different bandwidth than the first BWP configuration. The UE and BS communicate, for a duration of the communication of the plurality of reference signals for positioning, at least the plurality of reference signals for positioning in accordance with the second BWP configuration.

Abstract: Method and apparatus for switching between SS-TWR and DS-TWR. The apparatus reserves resources for transmission of a first SL-PRS in a first time slot. The apparatus transmits, to a second UE, the first SL-PRS within the first time slot. The apparatus receives, from the second UE, a second SL-PRS at a second time based on the first time slot and a response time associated with transmission of the second SL-PRS in response to the first SL-PRS. The apparatus measures a time difference between the transmission of the first SL-PRS and reception of the second SL-PRS to determine if a third SL-PRS is to be transmitted to the second UE.

Abstract: Aspects relate to an allocation of periodic resources where use of the periodic resources is conditional. In some examples, a user equipment (UE) receives a periodic resource allocation along with an indication of a condition for using the periodic resources. For example, the UE may be allowed to transmit on at least one first resource of the periodic resources if the condition is true. Similarly, a base station (BS) may monitor for a transmission by the UE on the at least one first resource if the condition is true.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a communications device determines at least one position estimation performance parameter, determines a zone identifier based at least in part upon the at least one position estimation performance parameter, wherein the zone identifier identifies one of a plurality of zones, and transmits the zone identifier to one or more UEs. A UE receives the zone identifier, determines the at least one position estimation performance parameter, selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the at least one position estimation performance parameter, and performs the sidelink-assisted position estimation procedure of the UE with at least the selected one or more candidate UEs.
