Abstract  Abstract

One aspect of the teachings given herein provides sending precoder selection feedback to the other transceiver (10) from the transceiver (12) (44) for the other transceiver (10) used as the precoder recommendation. transceiver (12) generates two types of precoder selection feedback (44) wherein one type than the other types of smaller signaling payload thus providing signalling overhead associated with reporting precoding recommendation is obviously reduced. transceiver (12) reduces the reporting overhead type use at certain times or on certain channels or response control signalling (48). In one example LTE network (80) in the UE (86) by transmitting only the index precoder (28) of subset (54) of small range index value (56) in order to transmit precoder information to the eNodeB (84) on the PUCCH but when on the PUCSH report full range index value (52) the full range of index values (52) index precoder (28) more sets (50).

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).
