Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, via a first interface of a repeater, information associated with a second interface of the repeater. The base station may determine a configuration for the second interface of the repeater based at least in part on the information associated with the second interface, and may communicate the configuration for the second interface of the repeater via the first interface. In some aspects, a repeater may transmit, to a base station via a first interface, information associated with a second interface of the repeater. The repeater may receive, via the first interface, a configuration for the second interface, and may configure the second interface based at least in part on the configuration. Numerous other aspects are provided.

Abstract: A method, a computer-readable medium, and an apparatus may include a receiving UE that is configured to receive at least a portion of a message for a service group, measure a signal strength for the message received, and determine whether to send feedback based on the signal strength measured for the message. In some aspects, a transmitting UE is configured to determine an intended range for a service group, and transmit a message for the service group based, at least in part, on the intended range. In some aspects, the transmitting UE is configured to receive HARQ feedback from at least one receiving UE, measure a signal strength for the HARQ feedback, and determine whether to resend the message based on the signal strength measured for the HARQ feedback.

Abstract: An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.

Abstract: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.

Abstract: The present disclosure relates to methods and devices for signaling enhancements. In one aspect, a User Equipment (UE) can receive a configuration to transmit one or more sounding reference signals (SRSs) based on a downlink control information (DCI). The UE can also receive an indication of a plurality of non-contiguous resource blocks (RBs) based on the DCI. The UE can transmit a first SRS on a first set of one or more RBs of the plurality of non-contiguous RBs. Additionally, the UE can transmit a second SRS on a second set of one or more RBs of the plurality of non-contiguous RBs. The first set of one or more RBs and the second set of one or more RBs may be separated by a distance of at least one RB.

Abstract: Aspects of the present disclosure provide techniques for dynamically adjusting the access link timing alignment at the integrated access and backhaul (IAB) node. Specifically, features of the present disclosure provide techniques for signaling to one or more child nodes the timing advance and timing offset values associated with each operational mode of the IAB node that may impact the access link timing for the child node (for uplink and/or downlink transmissions). Additionally or alternatively, aspects of the present disclosure identify whether a gap period may be included in order to ensure that the child node has sufficient time to transition between states during the transition period (e.g., from downlink to uplink) when the IAB node dynamically adjusts the access link timing.

Abstract: Aspects described herein relate to determining, based on a received signal strength, a set of potential backhaul nodes for providing a backhaul link in an integrated access and backhaul (IAB) network, determining, based at least in part on additional information regarding the set of potential backhaul nodes, at least one backhaul node of the set of potential backhaul nodes to which to connect over the backhaul link in the IAB network, and indicating, to an access node, the at least one backhaul node for attempting connection over the backhaul link.

Abstract: Disclosed are techniques for determining a beam-specific timing advance for Round-Trip Time (RTT) estimation. In an aspect, a first node receives a plurality of beams transmitted by a second node on a wireless channel, selects a first beam from the plurality of beams for transmitting a timing response, determines a timing statistic, a timing difference, and a timing advance for the first beam, wherein the timing difference comprises a difference between the timing statistic and an earliest time of arrival of the plurality of beams, and wherein the timing advance comprises a multiple of the timing difference, and transmits the timing response for the first beam to the second node on the wireless channel, wherein the first node transmits the timing response after a time delay from the timing statistic of the first beam, wherein the time delay comprises a difference between a predetermined time delay and the timing advance.
