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: Aspects herein relate to inter-cell interference randomization between two or more cells. For example, a network entity may determine a cell identifier associated with the network entity and perform at least one of an interleaving, rate-matching, or resource element mapping on at least one codeword based on the cell identifier. The network entity may further communicate with a user equipment (UE) in accordance with performing at least one of the interleaving, rate-matching, or resource element mapping on the at least one codeword. In another example, a UE may receive a message from a network entity on a communication channel and identify a cell identifier associated with the network entity. The UE may further perform at least one of a de-interleaving, de-rate-matching, or resource element de-mapping on the message based on the cell identifier.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on DL beam(s). The UE may identify a selected DL beam of the DL beam(s) for communications from the base station to the UE. The UE may transmit a random access channel (RACH) message to the base station using at least one of a resource or a RACH waveform selected based at least in part on the selected DL beam.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In some aspects, a base station may send a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The base station may send, in association with the beam modification command, a reference signal using at least one transmit beam of the set of transmit beams, where a first portion of the reference signal is sent in a first set of symbols and a second portion of the reference signal is received in a second set of symbols.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

Abstract: Certain aspects of the present disclosure provide techniques for protecting high priority symbols from beam switching. In some aspects, a method comprises identifying potential beam switching time spots in a time interval. The method further comprises determining a time interval configuration of the time interval based on the identified potential beam switching time spots, wherein the time interval configuration protects one or more high priority symbols from beam switching at the potential beam switching time spots. The method further comprises transmitting the time interval configuration to a user equipment (UE).

Abstract: Methods, systems, and devices for wireless communication are described that provide for selecting different uplink transmission parameters for transmission or retransmission of a random access message. A user equipment (UE) may retransmit a random access message to a base station during a random access procedure if an initial transmission of the random access message was unsuccessfully received by the base station. The UE may select a different transmission beam, uplink resource, or transmission power for retransmission of the random access message. The selection may be based on path loss associated with synchronization signals or previous transmissions. The selection may also be based on a maximum number of retransmissions.

Abstract: A first apparatus may send, to a base station in a first carrier frequency, a request associated with determination of a first beam used for communication between the base station and the UE. The first apparatus may communicate with the base station in a second carrier frequency based on the request associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency. A second apparatus may receive, from a base station in a first carrier frequency, a message associated with determination of a first beam used for communication between the base station and the UE. The second apparatus may communicate with the base station in a second carrier frequency based on the message associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency.
