Abstract: The disclosure relates to technology for identifying a user equipment beam index in a base station. The base station indicates one or more resources assigned to the user equipment within a beam failure random access channel (BRACH) resource, and transmits one or more synchronization signal block resources and one or more new beam identification reference signal resources to the user equipment. The base station then receives one of the resources from a group of the one or more resources within the BRACH resource assigned to the user equipment corresponding to the BRACH resource, and identifies a preferred beam index of the user equipment based on information in the BRACH resource and the received one of the resources.

Abstract: A method for resource and power allocation indication in a beam-based access system is provided. In an embodiment, a method for signaling power allocation in a beam-based access system includes determining, by a transmit point (TP), a relative effective transmit power offset between a control beam and a data beam. The method also includes signaling, by the TP, the relative effective transmit power offset to a user equipment (UE). The UE performs automatic gain control (AGC) on a control channel and a data channel according to the relative effective transmit power offset signaled by the TP.

Abstract: The disclosure relates to technology for beam failure recovery in user equipment. The user equipment sends a beam failure recovery request to the base station upon detection of a beam failure between the base station and the user equipment, and monitors one or more candidate beams in which to receive the beam failure recovery request response from the base station, based on an association between a beam failure recovery request response and a beam failure recovery request.

Abstract: A method and an apparatus for selecting beams for non-codebook based uplink multiple-input and multiple-output are disclosed. In an embodiment, a method implemented by a user equipment (UE) includes receiving an allocation of at least one sounding reference signal (SRS) resource in an uplink subframe from a transmission and reception point (TRP) for a first set of uplink transmission beams, transmitting precoded SRSs in the at least one SRS resource to the TRP, wherein the precoded SRSs are precoded with UE-selected precoders and at least one rank and receiving an identification of two or more precoders for a second set of uplink transmission beams, wherein the second set of uplink transmission beams is selected from the first set of uplink transmission beams, and wherein the two or more precoders are based on the precoded SRSs.

Abstract: When spatial quasi co-location is established between component carriers, beam management, e.g., beam configuration or reference signal configuration, of one component carrier may be performed based at least in part on beam management information of the other. Information specifying that component carriers or reference signals cross component carriers are spatially quasi co-located, or information about a SQCL group including spatially quasi co-located carriers, may be transmitted to a UE, e.g., using broadcast signaling, radio resource control (RRC) signaling, a media access control-control element (MAC-CE), downlink control information (DCI) signaling, or a combination thereof.
