A method by which a terminal performs a beam failure recovery (BFR) procedure in a wireless communication system, according to one embodiment of the present specification, comprises the steps of: receiving setting information related to a physical uplink control channel (PUCCH); transmitting the PUCCH on the basis of the setting information, the PUCCH being related to BFR of at least one secondary cell (SCell); and transmitting a message comprising information related to the BFR. The message comprising the information related to the BFR is related to a beam failure detected before a specific time point.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a channel state information reference signal (CSI-RS) Layer 3 (L3) signal corresponding to a first cell. The UE may select, based at least in part on an angle of arrival (AoA) difference between a first AoA and a second AoA, a UE reception (Rx) beam for receiving the CSI-RS L3 signal, wherein the first AoA is associated with the CSI-RS L3 signal, and wherein the second AoA is associated with a communication corresponding to a second cell. The UE may receive the CSI-RS L3 signal using the UE Rx beam. Numerous other aspects are provided.

A UE in a wireless communication system is disclosed. The UE includes a communication module and a processor for controlling the communication module. The processor determines a first cyclic shift (CS) value based on hybrid automatic repeat request acknowledgment (HARQ-ACK) information representing a response to a downlink channel having been received from a base station, determines a CS offset based on request information representing a request to be transmitted from the UE to the base station, determines a second CS value representing a degree of cyclic-shifting a base sequence to be used in a physical uplink control channel (PUCCH) based on the first CS value and the CS offset, and transmits the PUCCH for simultaneous transmission of the request information and the HARQ-ACK information using a sequence generated by cyclic-shifting the base sequence based on the second CS value.

Methods and apparatus for facilitating the use of a plurality of antenna beams for communications purposes are described. In at least some embodiments beam priority information is periodically exchanged. Multiple timers are used to ensure beam information is exchanged at intervals intended to facilitate reliable beam synchronization and to control switching to one or more alternative beams in a predictable manner in the event beam change information or beam synchronization information is lost. In some but not all embodiments a wideband beam is used to communicate beam synchronization information when synchronization using narrower beams used for normal data communication is lost.

Techniques for process based antenna configuration are described, and may be implemented via a wireless device to identify different usage scenarios and to adapt antenna configurations to optimize wireless performance based on the scenarios. For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios. The obstruction states are then correlated to antenna positions in the wireless device to prioritize (e.g., activate) antennas that are relatively unobstructed, such as by activating unobstructed antennas and/or deactivating obstructed antennas. Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process.

The present disclosure relates to a pre-5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). Disclosed is a method of identifying non-Line of Sight, NLOS, links between entities in a telecommunication network, comprising the steps of: determining if the link is NLOS and signaling from a first entity to a second entity a result of the determination by means of a parameter indicative of NLOS.

The present disclosure provides a beam failure recovery method, a beam failure recovery device and a terminal device. The beam failure recovery method includes: judging whether it is necessary to delay initiating a BFR procedure when a beam failure occurs for the terminal device in a DRX inactive state; directly initiating, by the terminal device, the BFR procedure when it is unnecessary to delay initiating the BFR procedure; and determining an initiation time point for the BFR procedure when it is necessary to delay initiating the BFR procedure, and initiating the BFR procedure at the initiation time point.

A subscriber module of a fixed wireless access communication system comprises an offset Gregorian antenna arrangement, an array of antenna elements arranged as a feed, a beamforming network and a processor.

The relationship between the azimuth and elevation direction of each feed beam and the azimuth and elevation direction of the respective beam from the primary reflector dish is a non-linear function of azimuth and elevation.

Certain aspects of the present disclosure to techniques for sidelink re-discovery without repeating beamforming in millimeter wave (e.g., Frequency Range 2) bands. For example, a Tx UE may complete a first beam training with a Rx UE. The Tx UE may generate a discovery message that includes at least one of: an indication of a beam training reference signal (BT-RS) sequence index of the first beam training; an indication of a timer for changing the BT-RS sequence; or an indication of a second BT-RS sequence to be used by the Tx UE before an expiration of the timer. The second BT-RS sequence may be indicated as an index to a set of BT-RS sequences including the BT-RS sequence associated with the first beam training. The Tx may transmit the generated discovery message to the Rx UE.
