Abstract: Aspects of sensor activation or deactivation for positioning a mobile device in a wireless communication network are disclosed. These aspects include, during a positioning session between the mobile device and a location server, determining with the location server that a first trigger condition or a second trigger condition has been met regarding reporting, by the mobile device to the location server, of sensor data from one or more sensors of the mobile device, where: the first trigger condition may comprise a trigger condition for activating the reporting, and the second trigger condition may comprise a trigger condition for deactivating the reporting. Aspects further include sending, from the location server to the mobile device, a message may comprise either: instructions to activate the reporting responsive to determining the first trigger condition has been met, or instructions to deactivate the reporting responsive to determining the second trigger condition has been met.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a sidelink message in accordance with one or more parameters associated with a priority of the sidelink message. The UE may determine a channel access priority class (CAPC) associated with the sidelink message based on the priority of the sidelink message. The UE may perform a listen-before-talk (LBT) procedure in accordance with the CAPC to gain access to a wireless channel for a channel occupancy time (COT). The UE may select a set of starting positions relative to the COT based on the priority, the CAPC, or both. The UE may transmit the sidelink message within the COT based on a starting position of the set of starting positions and the LBT procedure. The UE may perform a quantity of one or more retransmissions of the sidelink message based on the CAPC.

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.

Abstract: Methods, systems, and devices for wireless communications are described in which multiple operators may perform spectrum sharing using shared radio units (RUs), where the multiple different operators can access a same RU for communications with a user equipment (UE). A shared RU may receive requests for resources from two or more network nodes of two or more different network operators, for wireless resources in a first time period. The RU may determine a first resource allocation for the first time period based on different priorities of the different network operators. A first network operator may have a higher priority than a second or third network operator, and resources may be allocated to the first network operator ahead of the second or third network operators. The RU may transmit the first resource allocation to each of the different network nodes that transmitted requests for resources.
