Bandwidth adaptation for wireless communication system
Technology for a user equipment (UE) configured for bandwidth adaptation (BWA) is disclosed. The UE can decode resource allocation information for a first radio frequency (RF) bandwidth including a primary subband available to the UE for data communication. Th 5 e UE can decode resource allocation information for a second RF bandwidth, wherein the second RF bandwidth comprises the first RF bandwidth and at least one secondary subband available to the UE for data communication. The UE can encode data for transmission to a next generation NodeB (gNB) using resources allocated for the second RF bandwidth in the primary subband and the secondary subband. The UE 10 can have a memory interface configured to send to a memory the resource allocation information for the first RF bandwidth and the second RF bandwidth.
