    Abstract: A user equipment (UE) and a network node can support sounding reference signals (SRS) based antenna beam pair selection for simultaneous uplink transmission with multi-panels by the UE. One or more antenna beam pairs of a UE having a first antenna panel and a second antenna panel may be used to transmit SRSs to a first transmission reception point (TRP) and a second TRP simultaneously using SRS resources configured by one or more SRS configuration sets from the network node. The UE can configure a SRS spatial filter for a SRS resource to indicate a direction of an antenna beam, while some of the SRS resource is configured by the one or more SRS configuration sets received from the network node. The network node can select an antenna beam pair among the one or more antenna beam pairs based on indications of signal strength of SRSs received.

    Abstract: Apparatuses and systems for providing multiple structures to enable flexibility of a multiple transmission and reception point ultra-reliable low-latency communication (M-TRP URLLC) operation and reduce measurement effort and power consumption from a transceiving apparatus such as a UE are provided. The techniques disclosed here feature a transceiving apparatus including a transceiver and circuitry. The transceiver, in operation, receives signals from multiple transmission and reception points (M-TRPs) in a network on at least physical downlink shared channels (PDSCHs). The circuitry, in operation, performs beam failure recovery (BFR) by evaluating beam failure detection (BFD) and candidate new beam detection (CBD) for the signals from at least a first one of the M-TRPs. The signals from the first one of the M-TRPs comprise signals received on a physical downlink control channel (PDCCH), and the circuitry determines to skip evaluation of one or both of the BFD and the CBD for one or more additional ones of the M-TRPs in response to one or more conditions.

    Abstract: Disclosed herein is a first wireless communication node comprising a first communication module that includes a first baseband unit configured to handle baseband processing for the first communication module, a first RF unit configured to define a frequency range of radio signals for the first communication module, and a first antenna unit configured to generate a first extremely-narrow beam that facilitates exchange of radio signals with at least one other wireless communication node. The first wireless communication node may also comprise a second communication module that includes a second baseband unit configured to handle baseband processing for the second communication module, a second RF unit configured to define a frequency range of radio signals for the second communication module, and a second antenna unit configured to generate a second extremely-narrow beam that facilitates exchange of radio signals with at least one other wireless communication node.

    Abstract: Certain aspects of the present disclosure provide techniques for communicating uplink and downlink transmissions when a semi-statically configured scheduling occasion is overwritten by a slot format indicator. A method performed by a user equipment (UE) includes receiving a control message from a base station (BS) activating a semi-static scheduling configuration, wherein the semi-static scheduling configuration indicates a plurality of configured grant (CG) symbols in which the UE is scheduled to transmit at least one uplink transmission to the BS. The method may further include receiving, from the BS, a slot format indicator (SFI) that overwrites a subset of CG symbols of the plurality of CG symbols to be downlink symbols, and taking one or more actions to communicate at least one downlink transmission in the downlink symbols.

    Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a receiving device selecting a receive beam for receiving a signal from a transmitting device based on a relative direction of the transmit beam used to transmit the signal. A first wireless device may receive, from a second wireless device, an indication of a first angular range. The first angular range may be associated with a set of transmit beams for the second wireless device and correspond to at least two transmit beams of the set of transmit beams. The first wireless device may select a receive beam from a set of receive beams based on the first angular range and receive a reference signal, from the second wireless device, using the selected receive beam. The first device may also transmit channel information, to second wireless device, based on the reference signal.
