Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may signal quasi co-location (QCL) information to a first user equipment (UE). Based on the QCL information, the first UE may determine one or more QCL parameters for communications (such as a receive beam or a transmit beam) for uplink, downlink, or sidelink operations. The first UE may signal the determined QCL parameters to a second UE using a sidelink channel. The second UE may use the QCL parameters to configure a beam for a communication link that the second UE may use to communicate with one or more of the first UE via the sidelink channel, one or more other UEs via additional sidelink channels, or one or more base stations via uplink or downlink transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure a group wake-up signal based at least in part on a sidelink zone identifier that corresponds to a geographical area. The base station may transmit the group wake-up signal to collectively wake up at least a subset of user equipments (UEs) that are located in the geographical area corresponding to the sidelink zone identifier. Numerous other aspects are provided.

Abstract: Sidelink TX power control is disclosed. In a particular implementation, a method of wireless communication includes selecting, by a user equipment (UE), a first access link of multiple access links. Each of the multiple access links available for communication between the UE and a base station. The method also includes determining, by the UE, a sidelink transmission power based on the first access link. The method further includes transmitting, by the UE, data to an electronic device via a sidelink based on the sidelink transmission power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and/or a base station (BS) may identify in connection with a link failure of a primary cell, a resource in a secondary cell. The UE and/or the BS may communicate control signaling with the BS using the resource in the secondary cell as a response to the link failure of the primary cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: A first apparatus may receive, on a first control channel, information indicating a first set of resources allocated on a second control channel; send, to a second UE based on the first set of resources allocated on the second control channel, information associated with communication on a data channel; and send data to the second UE on the data channel based on the information associated with the communication on the data channel. A second apparatus may receive, on a first control channel, information indicating a first set of resources allocated on a second control channel; receive, from a second UE based on the first set of resources allocated on the second control channel, information associated with communication on a data channel; and receive data from the second UE on the data channel based on the information associated with the communication on the data channel.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a first beam measurement report from a second wireless device, the first beam measurement report indicating a first set of beam measurements for a wireless channel between the first wireless device and the second wireless device. The first wireless device may transmit to the second wireless device a cluster validity metric for at least one beam in the first beam measurement report. The first wireless device may receive from the second wireless device, in response to transmitting the cluster validity metric, a second beam measurement report indicating a second set of beam measurements for the wireless channel. The first wireless device may select a beam for transmitting to the second wireless device based at least in part on the first and second beam measurement reports.

Abstract: Methods, systems, and devices for wireless communications are described. Multiple user equipments (UEs) may communicate as part of a sidelink communications system. The UEs may identify a frame for a sidelink connection. The frame may include a control portion and a data portion. One UE of a pair of UEs may receive a data signal from the other UE of the pair, and the data signal may be received in the data portion of the first instance of the frame and in the control portion of a second instance of the frame. Another pair of UEs may attempt to reserve a subsequent data portion by transmitting a request signal in the control portion in the second instance of the frame, and the second pair of UEs may receive a suppression signal from the first pair of UEs indicating ongoing data transmission by the first pair of UEs.

Abstract: Disclosed are techniques for beam failure recovery in a wireless communications system. In an aspect, a user equipment (UE) detects a beam failure of a first downlink beam received at the UE from a base station, wherein the first downlink beam is a primary downlink beam for a first cell supported by the base station, sends, to the base station, on a supplementary uplink (SUL) beam, a message including an indication of the beam failure and an identification of a second downlink beam to replace the first downlink beam as the primary downlink beam for the first cell, and, based on the base station configuring the second downlink beam as the primary downlink beam for the first cell, establishes an uplink beam for the first cell based on properties of the second downlink beam.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a second UE, a first request message indicating a request to transmit a first sidelink message in a first slot of a sidelink network, and may transmit the first sidelink message in a first data section of the first slot based on transmitting the first request message. The first UE may monitor a first portion of a control section of a second slot of the sidelink network for request messages or response messages. The first UE may transmit a second request message in a portion of the second control section of the second slot designated for scheduling ongoing transmissions, and may transmit a second sidelink message in at least one portion of the second slot based on transmitting the second request message.
