    摘要: An apparatus and method for communicating control information (e.g., CQI, rank, and/or ACK/NACK) over a data channel (e.g., PUSCH) in the absence of user data includes storing a reference block size for transmission of control information of a first type (e.g., CQI) in memory of a wireless communication device. The reference block size is based on a predetermined quantity of information bits for the first type of control information. Responsive to a scheduling message containing an allocation of data channel transmission resources, the wireless device determines a quantity of the allocated resources to be encoded with control information of a second type (e.g., rank or ACK/NACK). The wireless device may further determine a quantity of the allocated resources to be encoded with control information of the first type and multiplex the encoded control information of the first and second types into a subframe for transmission over the data channel.

    摘要: A method and apparatus for generating a single statically defined downlink reference MCS table consisting of transport block sizes (TBSs) computed for 29 MCSs for each of j PRBs where j=1, . . . , NRBDL. Three entries of the MCS table are reserved for implicit modulation order signaling (e.g. in the downlink) or implicit redundancy version signaling (e.g. in the uplink). Each MCS entry in the table is populated by a TBS and the table entries are accessed based on a 5-bit MCS index and resource allocation information, indicating the number of PRBs is signaled via a scheduling message which may be a grant or assignment message. A grant or assignment message may further include a 5-bit MCS field for each transport block which, along with the resource allocation information, enables the UE to determine the scheduled TBS.
