Abstract: Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.

Abstract: Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a cell of a plurality of cells. The UE may selectively transmit a beam failure recovery request (BFRQ) communication for the cell based at least in part on a determination of whether a threshold time period has elapsed since a previous BFRQ communication was transmitted for the cell or another cell of the plurality of cells. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication relay may receive, via a first wireless link with a base station, a scheduling request that identifies scheduling information for scheduling transmission or reception of data via a second wireless link with a network node. The wireless communication relay may transmit, via the second wireless link, a scheduling command in accordance with the scheduling information. The wireless communication relay may transmit or receive, via the second wireless link, the data in accordance with the scheduling information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine a configuration for differential layer 1 (L1) signal to interference noise ratio (L1-SINR) reporting; transmit, to a user equipment (UE), an indicator of the configuration for differential L1-SINR reporting; and receive, from the UE, one or more differential L1-SINR reports in accordance with the configuration for differential L1-SINR reporting. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuring beam failure recovery operations. A method includes performing beam failure detection of a beam pair link associated with a secondary cell, wherein a user equipment (UE) is configured with one or more uplink control channel groups, each of the one or more uplink control channel groups comprising a corresponding plurality of component carriers where one of the corresponding plurality of component carriers is designated for communication of an uplink control channel for the corresponding uplink control channel group; determining one or more cells on which to send a beam failure recovery request (BFRQ) message based on a number of uplink control channel groups the UE is configured with; sending the BFRQ on the one or more cells; and receiving a beam failure recovery response message on at least one of the one or more cells.

Abstract: The apparatus determines, for a CC, an active TCI state of at least one of a CORESET of a PDCCH when the CORESET is configured on the CC or a PDSCH. In addition, the apparatus determines, based on the determined active TCI state, a default beam on the CC for transmitting at least one of a PUCCH or SRS. Further, the apparatus transmits at least one of the PUCCH or the SRS through the determined default beam on the CC.

Abstract: The present disclosure addresses selection of a modulation and coding scheme (MCS) for control information multiplexed on a data channel. A spectral efficiency associated with control information may be derived as a function of a spectral efficiency associated with data. A modulation order and/or code rate may be selected that is suitable for the spectral efficiency associated with the data. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine a first MCS for control information based on spectral efficiency associated with transmission of data, and further configured to transmit the control information with the first MCS, the control information being multiplexed with data.
