Abstract: A first access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field and one or more secondary change sequence fields. The first change sequence field indicates a presence or absence of a critical update associated with the first communication link, and each of the one or more secondary change sequence fields indicates a presence or absence of a critical update associated with a corresponding secondary communication link of the AP MLD. The first AP of the AP MLD transmits the frame over the first communication link of the AP MLD to a station (STA) of a STA MLD.

A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.

Abstract: A base station may transmit a set of CSI-RSs corresponding to a set of ports of a UE and the UE may perform a set of CQI measurements on each port and across each sub-band. The UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a best CSI-RS resource based at least in part on a corresponding set of M worst CQIs for the CSI-RS resource. The UE may report the M worst CQIs for the selected CSI-RS resource. Alternatively, the UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a worst CSI-RS resource. In this way, the UE enables the base station to select a DMRS port and/or an MCS to use for communication.

Abstract: Methods, systems, and devices for wireless communications are described that provide for the management of different operation modes in wireless systems. For example, wireless device(s) may operate in a high pathloss operation mode or a normal pathloss operation mode based on the pathloss experienced between the transmitting and receiving devices.

The message may be transmitted via control signaling and after receipt of the message, the second wireless device may enter a high pathloss mode for communications with the first wireless device (e.g., after a given time duration). Some parameters may be configurable (e.g., transmission duration, coding scheme) between high pathloss mode and normal pathloss mode, while other parameters may remain the same (e.g., processing time, switching time).

The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

Accordingly, the UE may transmit, or receive, within a slot, wherein the slot includes the PT-RS at the non-uniform density across a plurality of symbols of the slot.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.
