Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a base station (BS). In some examples, the techniques include receiving, from a user equipment (UE), one or more indications of one or more actual beam strengths as measured at the UE at one or more time periods for one or more transmit beams of the BS. In some examples, the techniques include receiving, from the UE, assistance information regarding the one or more actual beam strengths.

Abstract: Methods, systems, and devices for wireless communications are described in which one or more semi-persistent scheduling (SPS) configurations may provide periodic resources for communications between a base station and a user equipment (UE). One or more of the SPS configurations may also provide alternative resources that may be used for the communications in the event that a communication on the periodic or dynamically scheduled resources is cancelled. In the event that the base station transmits a cancellation indicator that cancels one or more of the communications, it may be determined whether to use the alternative resources for the associated communication. The determination to sue the alternative resources may be based on a time duration of the cancellation, a frequency portion of the cancelled resources, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to determine whether to request coverage enhancement for a random access procedure based on a condition of a channel between the UE and a base station failing to satisfy a threshold. The UE may transmit a request for coverage enhancement for a second random access message (e.g., a random access Message 4 (Msg4)) using a first random access message (e.g., a random access Message 3 (Msg3)). The base station may determine whether to perform the coverage enhancement in response to receiving the first random access message and may transmit the second random access message accordingly. Implementing aspects of the present disclosure may enable coverage enhancement for random access procedures in wireless communications systems.

Abstract: A user equipment (UE) may receive an indication associated with receiving downlink control information (DCI) communications. The indication may identify a first physical downlink control channel (PDCCH) monitoring location associated with receiving DCI communications during a first period of time, and a second PDCCH monitoring location associated with receiving DCI communications during a second period of time that follows the first period of time. The UE may monitor in the first PDCCH monitoring location and the second PDCCH monitoring location based at least in part on the indication.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for determining, such as by a user equipment (UE), a bundle size for demodulation reference signal (DMRS) bundling for an uplink random access channel (RACH) message sent with repetition and transmitting the uplink RACH message with DMRS bundling according to the determined bundle size. For example, in some aspects of the present disclosure, the uplink RACH message is sent with a number of repetitions and the bundle size is determined as a function of the number of repetitions. In some aspects, the bundle size is determined based on operation band. In some aspects, the bundle size is determined, based on a duplexing mode in which the UE is operating. In some aspects, the bundle size is determined, at least in part, based on signaling from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a number of channel state information (CSI) reports for a CSI reporting procedure as part of a beam management procedure. The UE may transmit a first number of CSI reports of the CSI reporting procedure to the base station using a first set of transmission parameters associated with a first reliability level. The base station may transmit a control message to the UE indicating a second set of transmission parameters associated with a second reliability level and the UE may transmit a second number of CSI reports of the CSI reporting procedure to the base station using the second set of transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described to support using one of multiple types of synchronization signal blocks (SSBs) to perform one or more management procedures. A base station may configure and transmit one or more SSBs of second type that are smaller than SSBs of a first type. For instance, SSBs of a second type may include a first subset of signals and may exclude a second subset of the signals that are included in an SSB of the first type. An SSB of the second type may be transmitted in an active bandwidth region used for communications between a user equipment (UE) and the base station. The UE may receive an SSB of the second type in an active bandwidth region, may perform one or more measurements using the SSB of the second type, and may perform one or more management procedures.

Abstract: Aspects presented herein may improve the efficiency of power boosting of PDCCH by a base station and the blind PDCCH detection/decoding performed by a UE. In one aspect, the UE receives, from a base station, a power boost indication for a PDCCH. The UE determines at least one search space based on the power boost indication from the base station. The UE monitors for the PDCCH with the indicated power boost from the base station in the at least one search space. In another aspect, a base station transmits, to a UE, a power boost indication for a PDCCH. The base station applies a power boost to the PDCCH. The base station transmits the PDCCH with the power boost to the UE.

Abstract: A UE may be configured to receive, from a base station, a downlink transmission on a downlink data channel including data and an indication of a beam switch; transmit first ACK feedback to the base station in response to receiving the data; and transmit second ACK feedback to the base station in response to receiving the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback. A base station may be configured to transmit, to a UE, a downlink transmission on a downlink data channel including data and an indication of a beam switch; receive first ACK feedback from the UE in response to transmitting the data; and receive second ACK feedback from the UE in response to transmitting the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station and a user equipment (UE) may perform beam refinement within a random access procedure. A UE may transmit a random access request to the base station and, in response thereto, the base station may transmit a control channel order to the UE that indicates to transmit a modified random access request. Resources for the modified random access request may be determined based on the random access request, the control channel order, configured resources, or combinations thereof. The base station may monitor for the modified random access request using different beamforming parameters and determine a refined beam for a subsequent transmission in the random access procedure. The base station may use the refined beam to transmit a random access response to the UE, and complete the access procedure.
