Abstract: Methods, systems, and devices for wireless communications are described. A first base station may transmit a request for a user equipment (UE) to provide a physical layer report for a second base station. The second base station may be a base station of a dual connectivity configuration, a deactivated base station of the carrier aggregation configuration, or a non-serving base station of the UE. The UE may measure transmissions of the second base station and generate, at the physical layer of the UE, a physical layer report based on the measurements. The UE may transmit the physical layer report to the first base station.

Abstract: Some wireless communication systems may operate in frequency ranges that are associated with beamformed transmissions between wireless devices. In such systems, a user equipment (UE) may be configured to monitor physical downlink control channel (PDCCH) on multiple beam pair links. In order to decode relevant downlink control information (DCI), a UE may perform multiple blind decodes on a control region of a downlink transmission. Blind decoding may be resource-intensive (e.g., computationally complex, energy consuming, etc.), but some systems may be efficiently designed to support the desired PDCCH monitoring via multiple beam pair links without significantly increasing the number of blind decodes at the UE. Aspects of such a design may include non-uniform candidate restriction, beam pair link-specific search spaces, and random control channel element (CCE) mapping across a candidate search space.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a list of transmission configuration indicator (TCI) state patterns where each entry in the list may correspond to a different TCI state pattern. The base station may transmit an indication of a selected entry from the TCI state pattern list and transmit a grant to the UE indicating that resources have been allocated in for transmitting a transport block (TB). The UE may receive the grant and attempt to receive the TB in accordance with the indicated TCI state pattern. The UE may generate multi-bit feedback to indicate whether the UE was able to successfully decode the TB and transmit the feedback to the base station. The base station may use the multi-bit feedback for determining whether to select a different TCI state pattern.

Abstract: Methods, systems, and devices for wireless communication are described that support overriding a beam monitoring pattern for control channel transmissions based on channel conditions between a user equipment and a base station. A base station may select a beam monitoring pattern for transmitting control channel transmissions, which may include a pattern in which two or more beams are used for control channel transmissions. In the event that a first beam of the beams used in the beam monitoring pattern meets certain metrics, the use of one or more additional beams according to the beam monitoring pattern may be overridden and transmissions continued using the first beam. The metrics for continuing use of the first beam may include channel quality metrics, a number of consecutive successful transmissions using the first beam, one or more other metrics, or any combination thereof.

Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.

Abstract: Methods, systems, and devices for wireless communication are described that support beam failure identification and recovery is systems that may use beamforming for uplink and downlink transmission beams. A first beam and a second beam may be configured, and the second beam may be used to identify a failure of the first beam. Upon detection of a beam failure, a beam recovery procedure may be initiated in which an indication of a beam failure may be transmitted using scheduling request (SR) or uplink control channel resource. A base station in some examples may transmit an indication that one of a set of beams may have failed, and a UE may provide an indication of which beam of the set of beams failed, such as based on a received reference signal associated with one of the beams.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive, a downlink control signal indicating that an uplink control signal is to be transmitted using two or more transmission beams during different transmission time intervals (TTIs). The UE may identify the two or more transmission beams based at least in part on the downlink control signal, and may transmit a plurality of repetitions of an uplink signal on the two or more transmissions beams. Each repetition may be transmitted on a different TTI using a different one of the two or more transmission beams based at least in part on the downlink control signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal identifying a first beam configuration and a second beam configuration to be used for performing a beamformed transmission of a physical uplink control channel (PUCCH) signal. The UE may determine, for a first PUCCH transmission occasion associated with the first beam configuration, that a communication metric associated with performing the beamformed transmission of the PUCCH signal using the first beam configuration fails to satisfy a threshold. The UE may perform, at a second PUCCH transmission occasion and based at least in part on the determining, the beamformed transmission of the PUCCH signal according to the second beam configuration.

Abstract: Wireless devices may employ techniques for indicating alternative modulation coding schemes (MCSs) (e.g., MCS values or MCS indices not associated with a default list or default MCS table). That is, communications (e.g., such as physical downlink control channel (PDCCH) transmissions carrying downlink control information (DCI), physical downlink shared channel (PDSCH) transmissions carrying uplink grants, etc.) may include information (e.g., in MCS fields and reserved fields) that indicate alternative MCSs for subsequent communications. For example, random access radio network temporary identifier (RA-RNTI) scrambled DCI, random access response (RAR) messages, etc., may indicate an alternative MCS for subsequent messages in a random access procedure (e.g., for a RAR, an RRC connection request, etc.). The alternative MCS may be conveyed by indicating information such as MCS scaling factors, alternative MCS table IDs, MCS indices associated with the alternative MCS table, or some combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may be configured to transition to communicating on a first bandwidth part from communicating on a second bandwidth part. In order to ensure that the UE is able to perform receiver processing for demodulating data received on the first bandwidth part, after transitioning to communicating on the first bandwidth part, the UE may be configured to perform receiver processing using reference signals received on the second bandwidth part. That is, for a configured period of time, before the UE is able to perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the first bandwidth part, the UE may perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the second bandwidth part.
