Abstract: A first apparatus may be implemented as a user equipment (UE) or a component thereof. The first apparatus may be configured to receive a pre-grant message from a base station on a wireless channel. The first apparatus may be further configured to determine an interference level associated with the wireless channel. The first apparatus may then indicate the interference level to the base station in response to the pre-grant message. A second apparatus may be implemented as a base station or a component thereof. The second apparatus may be configured to transmit a pre-grant message to a UE on a wireless channel. The second apparatus may be further configured to detect for an acknowledgement (ACK) message responsive to the pre-grant message from the UE. The second apparatus may then determine an interference level associated with the wireless channel proximate to the UE based on detecting for the ACK message.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may support beamforming communication techniques and may communicate using one or more beams. The UE may support a bandwidth part (BWP) hopping pattern and may perform a beam failure detection (BFD) procedure across the supported BWPs. While performing the BFD procedure, the UE may declare beam failure and may determine whether to switch to an anchor BWP to initiate a beam failure recover (BFR) procedure or to remain on an active BWP to initiate the BFR procedure. In some implementations, the UE may determine whether to switch to the anchor BWP or to remain on the active BWP to initiate the BFR procedure based on an indication from the base station.

Abstract: Method and apparatus for null-forming at bidirectional smart repeaters. The apparatus transmits, to a repeater, a repeater configuration. The repeater configuration configures the repeater to beam shape at least one beam of the repeater to suppress at least one side lobe of the at least one beam. The apparatus communicates with the repeater based on the repeater configuration. The apparatus receives, from the repeater, information related to an existing codebook of the repeater and associated beam forming capabilities of the repeater. The apparatus receives, from the repeater, information related to a null-forming codebook configured at the repeater.

Abstract: Methods and apparatus for wireless communication by a first user-equipment (UE). The method generally includes monitoring for signaling from a second UE during a DRX cycle associated with a DRX configuration for at least one of the first UE or the second UE, determining whether the first UE and the second UE are within range for communication based on the monitoring, and taking one or more actions based on the determination.

Abstract: Aspects relate to random access procedures. A base station may transmit a random access response message to a user equipment (UE) on a downlink control channel at a first monitoring occasion and transmit at least one repetition of the random access message at at least one offset from the first monitoring occasion. The base station may also transmit an indication of the offset(s) to the UE. Upon receiving the indication of the offset(s), the UE may monitor for the random access response message on the downlink control channel at the first monitoring occasion and at the monitoring occasion(s) for the repetition(s). A UE may identify a first radio network temporary identifier (RNTI) used to affect a physical downlink control channel (PDCCH) sent within a random access response (RAR) window and determine based on the first RNTI that the PDCCH is one of a plurality of PDCCH repetitions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a restriction on a combination of frequency components permitted to be used by the UE for carrier aggregation or frequency hopping, wherein the restriction indicates at least two frequency components that are not permitted to be combined for carrier aggregation or frequency hopping. The UE may communicate based at least in part on the restriction. Numerous other aspects are provided.

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect, a method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) that includes downlink control information (DCI). The DCI indicates a configuration of resources associated with RMSI repetition or RMSI slot aggregation. The method further includes monitoring for one or more RMSI messages based on the configuration of resources. The monitoring includes monitoring for multiple repetitions of an RMSI message based on the configuration of resources being associated with RMSI repetition and monitoring for a single RMSI message that is divided across multiple slots based on the configuration of resources being associated with RMSI slot aggregation. Other aspects are also claimed and described.
