Abstract: Techniques are described for reducing channel quality indication (CQI) reporting by user equipment (UEs) by selectively triggering the UEs to report CQI based at least on present physical location. UEs are controllable by base stations to toggle between active and inactive CQI reporting modes (inactive being the default mode). By default, base stations can make channel-state-based determinations based on previously reported CQI information stored as location-mapped CQI entries. Base stations can monitor the physical locations of UEs to determine when they are in locations with stale location-mapped CQI entries. If a UE is detected as being in such a location, a base station can direct the UE to toggle into active CQI reporting mode, thereby causing the UE to compute its CQI and transmit a CQI report. The base station can use the reported information to update the CQI score of the location-mapped CQI entry for that location.

A network access node may determine which beam pairs the repeater device cannot use for simultaneous transmission and/or reception and/or which beam groups the repeater device can use for simultaneous transmission and/or reception based on signal measurements and/or beam configuration feedback from the repeater device.

Abstract: A communication method, a communications apparatus, and a device are described. The communication operation carried out by a terminal includes receiving BWP indication information sent by a network device. The BWP indication information instructs the terminal to activate a BWP and/or deactivate a BWP. The communication operation further includes sending BWP feedback information to the base station. The BWP feedback information indicates that the terminal successfully received the BWP indication information. In this way, in the event of a data transmission failure because the UE cannot receive or cannot correctly parse the BWP indication information, the UE and the base station communicating by using different BWPs can be avoided, thereby improving communication quality.
