  • Patent number: 10999856
    Abstract: An approach for selecting sets of communications channels involves determining the performance of communications channels. A set of channels is selected based on the results of performance testing and specified criteria. The participant generates data that identifies the selected set of channels and provides that data to other participants of the communications network. The participants communicate over the set of channels, such as by using a frequency hopping protocol. When a specified time expires or monitoring of the performance of the channel set identifies poor performance of the set of channels, the participant selects another set of channels for use in communications based on additional performance testing. By selecting channels based on the initial performance testing and performance monitoring, the communications network adaptively avoids channels with poor performance.

Additionally, if any CORESET other than a CORESET-BFR has lowest CORESET ID, the UE will prioritize receiving that CORESET and may miss the BFR response. Accordingly, assigning a priority to CORESETs or search spaces during BFR may be preferable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may allocate a set of time-frequency resources to a plurality of CORESETs or a plurality of search spaces. The apparatus may assign a priority to each of the plurality of CORESETs or the plurality of search spaces. The apparatus may assign a highest priority to a CORESET for BFR or a search space for BFR.
