Abstract: A method, performed by a wireless communications device, for beam training with a radio access network of a wireless communications system. The wireless communications device is configured with a first set of multiple beams for a first beam training and a second set of multiple beams for a second beam training. The second set is different from the first set, the method including: performing the first beam training with the first set of multiple beams; calculating a channel metric associated with the wireless communications device based on the performed first beam training with the first set; selecting, for the second beam training, a subset of beams of the second set based on the calculated channel metric; and performing the second beam training with the selected subset.

Abstract: Methods for a communication node configured with an antenna array having a plurality of antenna elements. Such methods include determining a link metric for a data transmission received or transmitted using a first portion of the antenna elements, and determining a first value for a first function of the link metric and of a performance target for the link metric. Such methods include, based on the first value, selectively updating the first portion and a second portion of the antenna elements by a first number. The second portion is disjoint from the first portion. Such methods include concurrently performing the following when the updated second portion includes at least one antenna element: receiving or transmitting one or more data transmissions using a first beam formed by the updated first portion; and scanning for reference signal transmissions using a second beam formed by the updated second portion.

Abstract: A method, network node and wireless device (WD) for implementing network strategies for maximum bandwidth (BW) and maximum component carrier (CC) user assistance information (UAI) utilization are disclosed. According to one aspect, a method in a network node includes receiving UAI including an indication of at least one of a zero bandwidth for a frequency band and a component carrier to be disabled. The method also includes determining an allocation of at least one of a bandwidth and at least one component carrier based at least in part on whether the indicated at least one of the zero bandwidth and the component carrier to be disabled would exclude a primary component carrier by which the network node and the WD maintain communication in a cell.
