Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

An information transmission method can be applied to a user equipment, and include: when a beam failure recovery procedure is initiated for a first cell, initiating random access to a base station through a second cell, wherein the second cell is the first cell or another cell other than the first cell; and if the number of times random access is initiated without being able to complete the random access reaches a preset number, transmitting to the base station indication information for a problem existing in a cell group where the second cell is located, wherein the indication information is used to indicate that the cause for the problem existing in the cell group is the failure of random access caused by the initiation of the beam failure recovery procedure.

Embodiments of this disclosure provide techniques for receiving reference signals by a user equipment (UE) from a base station in a downlink channel, as well as transmitting a linear combination index from the UE to the base station. In particular, the linear combination index identifies a combination of beams selected from a set of beams in accordance with the RS.

Wireless communication is established between a first station and a second station in a wireless communication system, the first station having a beamforming network configured to form a succession of beams using antenna weight vectors selected from a pre-determined plurality of antenna weight vectors. The orientations of the beams are arranged in a grid comprising a plurality of rows. The beams of each row are spaced in angular position such that at least one beam in a respective row is positioned mid-way between the positions of two beams on an adjacent row. A succession of beams is formed to send first messages using a selected first sub-set of the antenna weight vectors. If a first message in a first beam is received at the second station, a further succession of beams is formed using a second sub-set of the antenna weight vectors selected to form beams adjacent to the first beam.

A communication method and system for converging a 5.sup.th generation (5G) communication system for supporting higher data rates beyond a 4.sup.th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal for handling scheduling request (SR) cancellation in a wireless communication system is provided. The method comprises identifying that at least one first SR is triggered, identifying whether each of the at least one first SR is triggered for beam failure recovery (BFR) of a secondary cell (SCell), and determining whether to cancel each of the at least one SR based on the identification.

Conditional handover (CHO) configurations may include random access channel (RACH) configuration information (e.g., beam quality thresholds, beam quality threshold offsets, one or more beams associated with configured contention free random access (CFRA) resources, one or more beams associated with configured contention based random access (CBRA) resources, or some combination thereof). A user equipment (UE) may, upon detection that a handover condition in a CHO configuration has been satisfied, select a target cell beam for transmission of a random access request based on the RACH configuration information included in the CHO configuration. In various examples, the selected beam may correspond to a highest quality beam with a highest quality beam measurement value above the beam quality threshold, a beam with an earliest configured CFRA resource or an earliest configured CBRA resource (e.g., if a corresponding beam measurement at least falls within the beam quality threshold offset), etc.

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for applying a common beam for multiple signals to a default beam for a physical downlink shared channel (PDSCH). An example method generally includes receiving, from a network entity, configuration information, identifying a common beam for wireless communications between the UE and the network entity based on the received configuration information, identifying a default beam based, at least in part, on the common beam and one or more rules, and receiving a physical downlink shared channel (PDSCH) by using the identified default beam.

The repeater receives control signaling including control information in association with traffic relayed through the repeater, between a first wireless communication device and a second wireless communication device, the repeater obtains a time division duplex state from the control information, obtains a fronthaul-link transmission control indicator (TCI) state index from the control information, obtains an access-link TCI state index from the control information, obtains a time domain resource allocation from the control information, and configures a relay unit of the repeater to communicate the traffic between the first wireless communication device and the second wireless communication device based the control information comprising at least one of: the time division duplex state, the fronthaul-link TCI state index, the access-link TCI state index, and the time domain resource allocation.
