Sub-band selection at cellular base station for non-overlapped or partially overlapped full duplex operation
摘要
說明書
The self-interference channel power corresponds to a portion of an RF signal transmitted by a local or collocated transmitter that couples into a receiver, e.g., the receiver's RF front end. By way of example, and without limitation, the example self-interference curve 221 may be obtained by initiating test transmissions at a number of frequencies across the entire frequency band being evaluated. The transmissions may occur sequentially, e.g., at regular and/or irregularly spaced intervals. The intervals may correspond to sub-bands 223, e.g., with one or more RF signals being transmitted in each sub-band. The sub-bands 223 may be determined according to a channel spacing, e.g., 1.4 MHZ, 3 MHz, 5 MHz, 10 MHz, 15 MHZ and/or 20 MHz. Alternatively or in addition, the sub-bands 223 may be determined according to a PRB allocation.
