Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may generate a first encryption key and a second UE may generate a second encryption key based on a measurement of a channel between the first UE and the second UE. The second UE may transmit, to the first UE, a sidelink message including a one-way digital signature generated using the second encryption key and a message from a defined set of messages. The first UE may generate a set of one-digital signatures using the first encryption key and the defined set of messages and determine whether the one-way digital signature matches one of the set of one-way digital signatures. If there is a match, the first UE and the second UE may communicate using the encryption keys. Otherwise, the first UE and the second UE may generate new encryption keys.

Abstract: Methods, systems, and devices for wireless communications are described. A relay device may detect an upstream radio link failure (RLF) associated with an upstream link of a wireless backhaul, where the wireless backhaul includes a first wireless link between the relay device and a first upstream backhaul device. The relay device may provide a first indication of the upstream radio link failure over a second wireless link between the relay device and a first downstream device. The relay device may establish a third wireless link with a second upstream backhaul device based on the detected upstream radio link failure. The relay device may provide multiple-access services to one or more downstream devices, where providing the multiple-access services is based on backhaul communications between the relay device and the second upstream backhaul device over the third wireless link.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) participating in a sidelink communications group increments a transmit counter for each packet transmitted by the first UE as part of group communications among the sidelink communications group, increments a receive counter for each packet received by the first UE from a second UE participating in the sidelink communications group as part of group communications among the sidelink communications group; and transmits the transmit counter and the receive counter to a network node based on a configuration received from the network node.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during an accumulation period, a plurality of transmit power control (TPC) commands that are based at least in part on one or more sidelink communications transmitted by the UE. The UE may determine a transmit power adjustment for the UE based at least in part on the plurality of TPC commands. The UE may selectively adjust a transmit power of the UE based at least in part on the transmit power adjustment. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling indicating a set of component carriers allocated for sidelink communications performed by the first UE. The first UE may receive a message indicating a subset of component carriers from the set of component carriers for use in communicating via a sidelink between the first UE and a second UE, where the subset of component carriers may be supported by the first UE and the second UE. In some cases, a base station or anchor UE may determine or configure the subset of component carriers for use between the first and second UEs. In some cases, the first UE, the second UE, or a both may determine the subset of component carriers. The first UE may communicate with the second UE via a component carrier from the subset of component carriers.

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.
