Abstract: Aspects relate to grouping sidelink carriers in a wireless communication network. A first wireless communication device, such as a user equipment (UE), may communicate with a base station on a cellular link utilizing a first set of first component carriers (CCs) in a particular frequency band. The UE may identify one or more first carrier groupings for the first set of first CCs with the base station. The UE may communicate with a second wireless communication device, such as a second UE, on a sidelink utilizing a second set of CCs within the same frequency band. The first UE may map at least one second CC to a respective corresponding first CC and apply the one more carrier groupings to the second set of CCs to generate one or more second carrier groupings based on the mapping.

Abstract: Aspects of the present disclosure relate to techniques for physical uplink control channel configuration and coverage enhancement in a wireless communication network. A base station can dynamically indicate a repetition factor for an uplink control channel to improve coverage of the uplink control channel. The base station can explicitly or implicitly indicate the repetition factor using various signaling techniques. The interpretation of an indication of a repetition factor can depend on one or more parameters, for example, a physical uplink control channel (PUCCH) format, an uplink control information size, a code rate, and/or a PUCCH resource set used for the PUCCH.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Aspects relate to measuring interference associated with sidelink communication. A UE that supports full-duplex communication may transmit on a first frequency resource and conduct self-interference measurements on a second frequency resource (e.g., a guard band) adjacent to the first frequency resource. Provisions may be made to ensure that other nearby wireless communication devices do not transmit on the second set of frequency resources when the UE is conducting an interference measurement. In a first resource allocation mode, a base station that allocates full-duplex resources for a first UE may ensure that any UEs that are near the first UE are not scheduled to transmit on a guard band when the UE is conducting an interference measurement. In a second resource allocation mode, a UE may reserve resources that are predefined with a guard band or the UE may reserve resources and use a subset of the resources for interference measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a cancellation indication, to drop one or more scheduled uplink communications associated with a first one or more scheduled uplink resources, in a group-common downlink control information message of a downlink control channel communication; identify, based at least in part on the cancellation indication, a second one or more scheduled uplink resources for a particular uplink communication; and transmit the particular uplink communication using the second one or more scheduled uplink resources. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enabling user equipment (UE) mobility within an area. In one aspect, a base station (BS) may configure a set of cells for serving a UE, as well as a set of relay UEs to relay communications for the UE, for example via sidelink communications. The BS may transmit control signaling to the UE indicating the configured set of cells and the set of relay UEs. The UE may establish communications links via sidelink connections with one or more of the relay UEs, and determine an activated subset of cells for data and control transfer. In some implementations, the UE may be configured to autonomously activate or deactivate relay UEs based on the mobility of the UE, and report the activation or deactivation to the BS.

Abstract: In an aspect, a communications device (e.g., UE, BS, LMF component, etc.) determines information related to a first positioning reference signal (PRS) configuration (e.g., UL-PRS configuration such as SRS-P, or DL-PRS configuration) associated with a user equipment (UE), determines information related to a first discontinuous reception (DRX) configuration associated with the UE, determines that a first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to a DRX limitation condition, and perform an action in response to the determination that the first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to the DRX limitation condition.

Abstract: Methods, systems, and devices for wireless communications are described. A relay node may establish a control plane connection between the relay node and a base station, wherein establishing the control plane connection comprises receiving from the base station a first network identifier for the relay node. The relay node may receive, via the control plane connection, a relay configuration from the base station. The relay node may monitor grants associated with a set of one or more user equipment (UEs) based at least in part on the relay configuration, each UE comprising a network identifier that is different from the first network identifier. The relay node may relay communications between the base station and the set of one or more UEs according to the monitoring.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.
