Abstract: Methods, apparatuses, and computer-readable mediums associated with a user equipment (UE) and a base station are provided for herein. In aspects, a UE may receive, from a base station, a beam modification command indicating at least one beam index for communicating through at least one beam on at least one channel. In an aspect, each beam index of the at least one beam index may indicate at least a direction for communicating through a corresponding beam of the at least one beam. The UE may communicate, with the base station, through the at least one beam corresponding to the at least one beam index on the at least one channel.

Abstract: Wireless communications systems and methods related to allocating resource blocks and resource block groups in a system band in order to reduce overhead associated with resource allocation. To reduce overhead, the wireless communication device communicates a signal in a control channel that indicates a general area and a resource block in the general area that stores data. The wireless communication device then communicates multiple resource blocks that include the resource block and communicates the data in the resource block using the signal. To reduce overhead, the wireless communication device also communicates multiple mappings for each resource block group into a set of resource blocks and a signal in a control channel that selects one of the multiple mappings. The communication device then determines resource blocks that are included in the resource block group according to the mapping, and communicates data in these resource blocks.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.
