摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node (400) and a receiving node (402). When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： Data is transmitted over multiple input multiple output (MIMO) channels. Plural bit streams are modulated into multiple data symbol vectors. Each vector has a transmission rank with one vector for each MIMO channel. Transmission rank is the number of elements in a data symbol vector corresponding to the number of data streams being transmitted in parallel over each MIMO channel. The multiple data symbol vectors are preceded into multiple precoded symbol vectors using a plurality of precoder cycling sets, one set for each transmission rank including multiple different precoders. The precoders in each precoder cycling set are well-separated with respect to a plurality of distance measures. The precoding includes precoding each data symbol vector of a transmission rank with a precoder belonging to the precoder cycling set of that transmission rank. The precoded symbol vectors are then transmitted over the MIMO channels.

摘要： A method for wirelessly transmitting data and control information, using a plurality of transmission layers includes determining a number of bits in one or more user data codewords (122) to be transmitted during a subframe and calculating a number of control vector symbols (124) to allocate to control information during the subframe.

The estimate of the number of vector symbols (124) depends, at least in part, on the number of control vector symbols (124) to be allocated to control, information. The method also includes mapping one or more control codewords (120) to the calculated number of control vector symbols (124) and transmitting the user data vector symbols (124) and the control vector symbols (124) over a plurality of transmission layers during the subframe.

摘要： 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.
