One aspect of the teachings presented herein provides advantages for sending precoder selection feedback (44) from a transceiver (12) to another transceiver (10), for use by the other transceiver (10) as precoding recommendations. The transceiver (12) generates two types of precoder selection feedback (44), where one type uses a smaller signaling payload than the other and therefore provides a distinct reduction in the signaling overhead associated with reporting precoding recommendations. The transceiver (12) uses the reduced-overhead type of reporting when reporting at certain times, or on certain channels, or in response to control signaling (48). In one example, a UE (86) in an LTE network (80) sends precoder information to an eNodeB (84) on the PUCCH by sending smaller-range index values (56) that index only a subset (54) of precoders (28), but sends full-range index values (52) when reporting on the PUSCH, which index a larger set (50) of precoders (28). |
