Abstract:
Efficient techniques to signal codebook subset restriction bit maps are provided. In some embodiments, a method of operation of a node of a cellular communications network includes determining a codebook restriction for a wireless device. The codebook restriction reduces a full codebook of the wireless device to a reduced codebook. The method also includes providing the codebook restriction to the wireless device with an indication of one or more ranks to which the codebook restriction applies. In some embodiments, this enables reduced signaling overhead from upper layers, improving the throughput of data traffic channels. This may also enable reduced RRC signaling message failures and also reduced latency.

Claim (Index 61):
A User Equipment, UE, adapted to:\n receive a codebook restriction with an indication of one or more ranks of a plurality of ranks to which the codebook restriction applies, the codebook restriction being a restriction that reduces a full codebook of the wireless device to a reduced codebook, the full codebook comprising precoding matrices for the plurality of ranks; and transmit channel feedback to a node of a cellular communications network based on the codebook restriction.
