Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for training a beam for multiple component carriers (CCs) for concurrent communications in a wireless communications system associated with limited user equipment (UE) capabilities. The UE receives, via a first receive beam, a first reference signal on a group of CCs over a first symbol. The UE also receives, via a second receive beam, a second reference signal on the group of CCs over a second symbol. The UE selects a receive beam for a subsequent communication based on determining a value of a parameter for each of the first and the second receive beam.

Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.

Abstract: It is recognized herein that as the number of transmit antennas in cellular systems (e.g., NR or 5G systems) increase, the Channel State information (CSI) feedback overhead may increase to unacceptable levels, and the current CSI feedback might not support beamforming training for NR. Embodiments described herein provide an enhanced and more efficient design for Channel State Information feedback as compared to current approaches.

Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

Abstract: A first network node may transmit, to one or more second network nodes, one or more first reference signals. The first network node may receive, from one or more third network nodes, one or more second reference signals. The first network node may measure a CLI level associated with at least one third network node in the one or more third network nodes based on the one or more second reference signals. In one or more configurations, the first network node may receive, from a network entity different from the first network node, a configuration associated with the transmission of the one or more first reference signals or the reception of the one or more second reference signals. In one or more configurations, the one or more second network nodes and the one or more third network nodes may or may not include at least one same network node.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a beam configuration for each physical cell identifier (PCI) of a set of candidate PCIs. A beam configuration for a PCI may include, for example, transmission configuration indicator (TCI) states for downlink channels and reference signals or spatial relations for uplink channels and reference signals. The UE may receive an indication of a selected subset of PCIs of the set of candidate PCIs. The UE may apply the beam configuration for each PCI of the selected subset of PCIs based on the indication of the selected subset of PCIs. The UE may then communicate according to the beam configurations for the selected subset of PCIs.

Abstract: A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.

Abstract: Aspects relate to reporting beam failure. Upon detecting a beam failure, a user equipment (UE) may transmit a beam failure recovery request to a base station. If the uplink is working, the UE may transmit the beam failure recovery request via uplink signaling (e.g., via a physical uplink control channel or a physical uplink shared channel). If the uplink is not working or if the beam failure is due to downlink quality degradation, the UE may transmit the beam failure recovery request via a random access channel (RACH) message.

Abstract: A configuration for reporting a beam application time for a specific beam at an antenna panel of a UE. The apparatus transmits, to a base station, a beam application time report for at least one antenna panel of the UE, wherein the beam application time report comprises a time for application of a beam for use by the at least one antenna panel. The apparatus applies the beam at the at least one antenna panel of the UE based on the beam application time report in preparation of communication with the base station. The apparatus communicates with the base station using the beam of the at least one antenna panel at least at a time based on the beam application time report.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first UE (e.g., aggressor UE) receives PL RS from a second UE (e.g., victim UE). The first UE determines a PL associated with the PL RS (e.g., based on a transmission power of the PL RS). The first UE performs one or more transmissions, in one or more full duplex (FD) resources, one or more transmissions with a transmission power that is based at least in part on the PL associated with the PL RS (e.g., PL may be used to determine a maximum transmission power that functions as a power control constraint on a power control algorithm that sets the transmission power). In this manner, CLI at the second UE may be reduced. In some designs, a network entity (e.g., base station) configures the PL RS.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes shifting, based on a partial overlap between a scheduled downlink transmission occasion and a scheduled uplink transmission occasion that each include a first and second repetition, a first repetition boundary of one transmission occasion of the downlink transmission occasion or the uplink transmission occasion, and performing full duplex communication with repetition based on the shifted first repetition boundary. In some implementations, shifting includes shifting an entirety of the one transmission occasion. In some implementations, shifting the first repetition boundary changes a number of consecutive symbols included in the first repetition of the one transmission occasion.

For example, the communication device may measure the level of self-interference of the received beam based on the transmitted RACH signal including the RACH preamble. The communication device may operate in a mode based on the determined level of self-interference.
