Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for indicating a sidelink configuration for synchronization signal transmission. For example, a user equipment (UE) may establish an access link with a base station or transmission/reception point. The UE may measure a plurality of beams of the access link or of a sidelink channel to generate a signal metric of the access link or of the sidelink channel. Based on the generated signal metric, the UE may identify a sidelink configuration for synchronization signal transmission within the sidelink channel. In some cases, the UE may transmit a synchronization signal via the sidelink channel based at least in part on the sidelink configuration.

Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: A device receives a coded message from a re-transmitting device designated by one or more devices for performing message re-transmission on their behalf. The coded message encodes a first message and a second message, where the receiving device has failed to receive at least the second message. The receiving device further receives a coding-based re-transmission indicator indicating that the coded message is configured as a coding-based re-transmission of two or more previously transmitted messages that are encoded together in the coded message. The receiving device recovers the second message by decoding the coded message. In another aspect, a re-transmitting device is designated by one or more devices for performing message re-transmission on behalf of the devices. The device generates a coded message that encodes a first and a second message; and transmits the coded message and an indicator indicating that the coded message is a coding-based re-transmission.

Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish connectivity to a local area network using cellular radio access technology (RAT). The UE may establish a signaling radio link with a cellular access node (AN) via a cellular RAT. The UE may transmit a connectivity request to a network node via the signaling radio link. The connectivity request may specify a connectivity type for establishing connectivity to a LAN. Based at least in part on an acceptance of the connectivity request, the UE may establish a data radio link with the cellular AN. In an example, the acceptance of the connectivity request may include at least one parameter for configuring the connectivity to the LAN. The UE may then establish a data flow for exchanging data link layer packets with the LAN via the data radio link.

Abstract: Methods, systems, and devices for wireless communication are described. Relocation of a user plane may be minimized through the exchange of communication session information between network nodes. For example, a connectivity session manager and an access and mobility manager may exchange information associated with a user equipment (UE) communication session to prevent unnecessary reestablishment of an existing communication session. In such cases, the access and mobility manager may receive a session management request from a UE and send a request including the session management request to the connectivity session manager. Based on the received message, the connectivity session manager may identify a continuity mode, select a user plane anchor for the communication session, and send a response message to the access and mobility manager. In some examples, the connectivity session manager and the access and mobility manager may exchange session area codes associated with the location of the UE.
