Abstract  Abstract

One aspect of the teachings of the claims by definition sets (80 86) identification of a conversion precoder and a tuning precoder (74 76) allows the subset (84-1 84-2) for signalling defined codebook wherein the conversion precoder and a tuning precoder (74 76) of the corresponding pair in the corresponding overall precoder (28) definition sets (26) of corresponding overall precoder (28). allowing a subset (50) of the overall precoder (28) definition sets (26) in overall precoder (28) through from the transceiver (10) sends the permitted subset (84-1 84-2) to a remote transceiver (12) for restricting signaling (48) to identify the conversion precoder and a tuning precoder (74 76) is indicated. the remote transceiver (12) using the defined signalling (48) the selection limitation of the overall precoder (28) to the overall precoder (28) allows the sub-set (50) The conversion precoder and a tuning precoder (74 76) corresponding to the subsets (84-1 84-2) defined with reference to the accompanying drawings.

One aspect of the teachings herein relates to signaling codebook restrictions to restrict the precoder recommendations being fed back from a remote transceiver (12) so that precoder selections made by the remote receiver (12) are restricted to permitted subsets (50) of overall precoders (28) within a defined set (26) of overall precoders (28) or to permitted subsets (84) within larger sets (80 86) of conversion precoders (74) and tuning precoders (76) for the case where the overall precoders (28) are represented in factorized form by conversion and tuning precoders (74 76). As a non-limiting example these teachings advantageously provide for precoder restrictions in LTE or LTE-Advanced networks where ongoing development targets the use of larger richer sets of precoders and where the disclosed mechanisms for determining signaling and responding to subset restrictions provide significant operational advantages.
