Abstract: In an aspect, a UE may perform clock synchronization in accordance with a first network timing reference, such as a unicast network timing reference (UNTR) or a broadcast networking timing reference (BNTR). The UE may detect event(s) associated with a connection to a BS, which may trigger a switch between the UNTR and the BNTR for clock synchronization. In a further aspect, a communications device (e.g., UE or BS) may determine to transition a UE between the BNTR and UNTR for clock synchronization, and may perform one or more actions to facilitate the network timing reference transition.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for operating a user equipment (UE) in a next generation (NG) radio access network (RAN) (NG-RAN) to validate a system information block (SIB) for non-public networks (NPNs). In one aspect, a UE receiving a SIB-one (SIB1) from a cell of the NG-RAN may determine whether the cell supports non-public networks (NPNs) based on the received SIB1. If so case, the UE may determine whether an NPN-identifier (NPN-ID) in the received SIB1 matches an NPN-ID of a SIB stored in memory. If so, the UE may validate the stored SIB based at least in part on the received SIB1. If not, the UE may invalidate the stored SIB and obtain a new SIB per standard procedures.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that processing or transmission associated with a scheduling request is preempted, and perform one or more scheduling request preemption actions, associated with the scheduling request, based at least in part on determining that the processing or transmission is preempted. Numerous other aspects are provided.

Abstract: A non-MNO PSP network maintains a table that maps external subscriber identifiers of UEs to intermediate subscriber identifiers of the UEs on an interface between the non-MNO PSP network and NHN(s). The non-MNO PSP network obtains an SCEF-related message including either an external subscriber identifier or an intermediate subscriber identifier for the UE. Using the table, the non-MNO PSP network forwards the SCEF-message to a serving NHN or to an external application. In another embodiment, an NHN maintains a table that maps internal identifiers of UEs within the NHN to intermediate subscriber identifiers that identify the UEs on an interface between the NHN and non-MNO PSP(s). The NHN obtains an SCEF-related message that includes an intermediate subscriber identifier or an internal identifier for the UE. Using the table, the NHN either processes the SCEF-related message within the NHN, or forwards the SCEF-related message to a non-MNO PSP outside the NHN.

Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device. The packet delivery window configuration may indicate a periodicity, offset, start time, end time, and/or duration of the delivery windows, among other information. Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.

Abstract: Methods, systems, and devices for wireless communications are described that provide for timing synchronization among one or more time sensitive network (TSN) endpoints via a wireless communications network. A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently scheduling semi-persistent scheduling (SPS) downlink transmissions and dynamic downlink transmissions to maximize throughput in a wireless communications system. In one example, a user equipment (UE) may receive downlink data in a dynamic downlink transmission and receive the same downlink data or no data in an SPS downlink transmission when the dynamic downlink transmission is scheduled to occur after the SPS downlink transmission and before an uplink feedback transmission for the SPS downlink transmission. In another example, a UE may receive downlink data in a dynamic downlink transmission and receive the same downlink data or no downlink data in an SPS downlink transmission when the SPS downlink transmission is scheduled to occur after the dynamic downlink transmission and before an uplink feedback transmission for the dynamic downlink transmission.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may be configured to transmit more than one set of semi-persistent scheduled (SPS) transmissions to a base station. The base station may indicate, within the configuration, a group of SPS transmission sets. The base station may determine to reconfigure one or more of the SPS transmission sets (e.g., due to a change in channel conditions). The base station may indicate an updated configuration for the more than one SPS transmission sets via a single downlink control information (DCI) message. In some cases, the more than one SPS transmission sets corresponds to the group of SPS transmission sets. After receiving the updated configuration for the SPS transmissions sets, the UE may adjust the SPS configurations accordingly and communicate with the base station using the adjusted configurations.
