Efficient operation with unlicensed downlink (DL) and licensed uplink (UL) by transmission of selective DL messages using licensed UL

Abstract:

Wireless communications systems and methods related to operating in a network deployed in a downlink (DL) unlicensed band and an uplink (UL) licensed band are provided. A first wireless communication device communicates, with a second wireless communication device, a first downlink communication signal in a downlink unlicensed band of a network. The first wireless communication device communicates, with the second wireless communication device, a second downlink communication signal in an uplink licensed band of the network. The second downlink communication signal includes at least one of a synchronization signal block (SSB), system information, a random access response, a contention resolution message, paging information, a downlink feedback signal, or low-latency data.
