Techniques to enhance user equipment (UE) beam scan
A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.
Radio link monitoring across multiple frequencies in wireless communications
Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Techniques for self-interference cancelation
Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a control node, an indication of a capability of the first wireless node to perform one or more self-interference cancelation (SIC) procedures between a first antenna array of the first wireless node and a second antenna array of the first wireless node. The first wireless node may receive, from the control node in response to the indication of the capability, a configuration for the first wireless node to use to perform a SIC procedure of the one or more SIC procedures for full-duplex communications. The first wireless node may then communicate, according to the received configuration, with the control node, a control node, or any combination thereof, using the first antenna array and the second antenna array.

Channel state information feedback methods and systems
Disclosed are methods, systems and devices for channel state information feedback to facilitate, for example, high-performance beamforming or precoding in multiple input multiple output (MIMO) systems. One example method includes performing multiple transmissions of a channel measurement report on multiple transmission occasions. Another example method includes performing multiple receptions of a channel measurement report on multiple reception occasions, where the multiple receptions at a network node correspond to multiple transmissions from a wireless device. In both exemplary methods, a timing of the multiple transmissions is based on at least one of a number of the multiple transmission occasions, a time gap between adjacent transmission occasions of the multiple transmission occasions, and one or more timeslots that include the multiple transmission occasions.

Listen-before-talk (LBT) failure detection in dormant cell and outside discontinuous reception (DRX) active time
Wireless communications systems and methods related to communications in a network are provided. A UE receives a listen-before-talk (LBT) failure detection configuration associated with at least one of a dormant mode or a discontinuous reception (DRX) cycle in a first cell of a wireless communication network. The UE performs, based on the LBT failure detection configuration, an LBT failure detection in the first cell while operating in the dormant mode for the first cell or during an inactive DRX configured-on duration of the DRX cycle. The UE transmits an LBT failure detection report based on the LBT failure detection.
