The resource configuration information may indicate downlink symbols within a carrier bandwidth for downlink communication, uplink symbols within the carrier bandwidth for uplink communication, and NOSB-FD symbols within the carrier bandwidth. Each NOSB-FD symbol may be configurable for both uplink and downlink communication. For any one of the NOSB-FD symbols, one or more uplink subbands within the carrier bandwidth may be configurable to be allocated for uplink communication and one or more downlink subbands of the carrier bandwidth may be configurable to be allocated for downlink communication. The resource configuration information may be determined from a mapping of physical resource blocks (PRBs) to a common resource block (CRB) grid. ## Claims ### Claim 1 A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) network, the UE comprising: processing circuitry;
