Sub-band selection at cellular base station for non-overlapped or partially overlapped full duplex operation
摘要
說明書
According to duplex operations, the radio terminal 212 may simultaneously support both the downlink radio signal 213a and the uplink radio signal 213b. It is understood that simultaneous operation of the downlink radio signal 213a and the uplink radio signal 213b may result in one or more forms of interference. For example, a self-interference 217 may include interference experienced at the receiver of the radio terminal 212, due to transmit operation of the transmitter of the radio terminal 212. Another form of interference is referred to as cross link interference 218, which may include interference experienced at a receiver of the first mobile communication device 214a, due to transmit operation of a transmitter of the second mobile communication device 214b.
It is understood that the example non-limiting embodiment of a full-duplex, sub-band selection system 210 may be adapted to operate in support of one or more mobile cellular communication services, such as those commonly referred to as 3G, 4G, 4G NR and 5G services. Operational aspects related to the example mobile cellular communication services may be disclosed, defined and/or otherwise standardized according to standards organizations, such as the 3GPP. Accordingly, it is understood that in at least some embodiments, downlink operation may utilize OFDM, with twelve (12) subcarriers arranged according to 180 kHz spacings. User and/or control data may be mapped into OFDM symbols, and provided as parallel sets of 12 OFDM symbols according to the 12 subcarriers of a physical resource block (PRB). For example, the OFDM symbols are mapped in each 0.5 msec time slot in groups of 7 symbols.
