Abstract  Abstract

one aspect of the present teachings relates to signaling codebook defined to define suggested from precoder feedback remote transceiver (12). allowing subset (50) to a remote receiver (12) pre-coder selection is defined in the definition set (26) of overall precoder (28) overall precoder (28) or represented by a conversion precoder and a tuning precoder (74 76) to factor decomposition form the overall precoder (28) lower. in the larger set (80 86) defines a conversion precoder (74) and tuning precoder (76) allows the subset (84). As a non-limiting example these teachings advantageously provide for precoder in LTE or LTE-advanced network wherein the ongoing development of the precoder is large more abundant set as a target and wherein the device for determining sending signal notification and response subset defined claims mechanism providing significant operating advantages.

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.
