Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: A base station central unit (CU) may receive a measurement report from one or more user equipments (UEs). The CU may identify a scheduling plan indication (SPI) for one or more scheduling nodes in a network, based at least in part on the received measurement reports. The SPI may specify a pattern of scheduling states, over a period of time, to be used by the one or more scheduling nodes to schedule communication resources for one or more UEs in the network. The scheduling states may (e.g., based on an interference profile determined from the received measurement reports) specify UEs or other communication resources for transmission scheduling decisions made by the scheduling nodes, or may specify beam patterns for beamforming procedures performed by the scheduling nodes. In some cases, the scheduling nodes may identify tentative SPIs, which the CU may pass amongst other scheduling nodes for distributed scheduling coordination schemes.

Abstract: Methods, systems, and devices for multiple random access channel (RACH) message 1 (Msg1) transmission for physical downlink control channel (PDCCH) ordered RACH are described. A user equipment (UE) may perform the multiple Msg1 transmission as part of a CFRA or CBRA procedure for access. The UE may perform the multiple Msg1 transmissions in a cyclic consecutive manner during configured RACH occasions or according to explicit time and frequency indications of a random access response (RAR) window. Based on the multiple Msg1 transmission procedure, the UE may reduce latency for random access procedure on the RACH and improve signaling throughput. In some cases, the UE may support beam correspondence and may perform multiple Msg1 transmissions to enhance multi-beam diversity during RACH transmission by performing transmission corresponding to RACH occasions mapped to different synchronization signal blocks (SSBs).

Abstract: Various aspects include methods for receiver (RX) beam sweep configuration of a millimeter wave (MMW) repeater during random access channel (RACH) procedures. Various embodiments may include determining two or more different RX beam sweep configurations for one or more RACH occurrences (ROs) associated with a synchronization signal block (SSB), generating a RACH configuration message indicating the two or more different RX beam sweep configurations for the one or more ROs, and sending the RACH configuration message to an MMW repeater. Various embodiments may also include receiving a RACH configuration message indicating two or more different RX beam sweep configurations for one or more ROs associated with an SSB, and controlling one or more RX antennas of the MMW repeater to perform RX beam sweeping during the one or more ROs according to the RACH configuration message to receive a RACH message 1 from a computing device.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a measurement configuration, from a second wireless device, to support full-duplex operation using a shared resource. The first wireless device may transmit, via the shared resource, a first signal via a first transmission beam using a first antenna array of the first wireless device. The first wireless device may monitor, in accordance with the measurement configuration, the shared resource using a first receive beam via a second antenna array of the first wireless device. The first wireless device may then transmit a measurement report to a second wireless device based on the monitoring. The second wireless device may transmit, to the first wireless device, a duplexing configuration configuring the full-duplex operation of the first wireless device based on the measurement report.

Abstract: Various aspects include methods for beam sweep configuration of a millimeter wave (MMW) repeater in a fifth generation (5G) network during random access channel (RACH) procedures. Various embodiments include receiving an RACH 1 message relayed by an MMW repeater, determining a beam sweep schedule for use by the MMW repeater in relaying a random access response (RAR) message in response to the RACH 1 message, wherein the beam sweep schedule indicates a series of RAR messages to be sent successively and a different transmit (TX) beam sweep configuration to be used by the MMW repeater for each of the series of RAR messages, generating an RAR control message indicating the beam sweep schedule, sending, by the processor of the network device, the RAR control message to the MMW repeater, and sending the series of RAR messages to the MMW repeater.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a collective antenna array that includes both a downlink antenna array and an uplink antenna array for communications with a second wireless device. Accordingly, the first wireless device and the second wireless device may perform a beam training procedure on the collective antenna array, and the first wireless device may then use beam weights identified for the collective antenna array as the beam weights for the specific downlink antenna array and the uplink antenna array. For example, the first wireless device and the second wireless device may perform downlink beam training to obtain a best downlink receive beam to use and then determine an uplink transmit beam to use based on the downlink receive beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may dynamically select subsets of antenna elements within an array based on power consumption and link performance and/or a configuration of components at the wireless device. For example, a wireless device may identify an antenna array having multiple antenna elements, and the wireless device may select respective subsets of antenna elements (e.g., subarrays) for uplink and downlink transmissions. In such cases, the selection may be based on a tradeoff of power consumption at the device and link performance. Additionally or alternatively, the selection may be based on a configuration and/or constraints on a number of radio frequency (RF) components of the wireless device. The wireless device may communicate based on the dynamic selection of different subsets of antenna elements of an array for uplink and downlink communications.
