摘要： A beam selection method and apparatus suitable for millimeter wave (mmW) communication systems is disclosed. In one aspect, a user equipment (UE) may perform a beam sweep procedure to identify suitable downlink beams candidates from one or more gNBs. The UE may generate a beam list by selecting some of the downlink beams for active tracking. When beams on the beam list become unavailable, the UE may compare the number of available beams on the beam list with a threshold value. If the number of available beams falls below the threshold, the UE may perform another beam sweep procedure.

摘要： Aspects of the present disclosure include methods, apparatuses, and computer readable media for inserting an offset between a channel resource element of a channel resource block and a synchronization resource element of a synchronization signal block, transmitting a bandwidth value of the offset to a user equipment.

摘要： Techniques and apparatuses described herein permit selective multiplexing of synchronization signal blocks (SSBs), inside of or outside of an SSB measurement timing configuration (SMTC) window, and downlink channel communications depending on one or more factors, which may increase spectral efficiency due to multiplexing when permitted, and may prevent or reduce collisions and interference when not permitted (e.g., due to quasi co-location constraints, processing constraints, timeline constraints, and/or the like).

摘要： Wireless communications systems and methods related to performing initial network access procedures using shared resources are provided. A first wireless communication device transmits, in a first frequency band, a random access request to a first network. The first wireless communication device receives, in response to the random access request, a random access response from a second wireless communication device of the first network. The random access response is in a second frequency band allocated to the first network for time-division duplexing (TDD) communications. The second frequency band is different than the first frequency band.
