Abstract: 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.

Abstract: When a UE (102) determines that non-control data needs to be transmitted, the UE will receive a grant that comprises information identifying a resource block (RB) for transmissions by the UE. If the UE determines that the RB is also used for transmitting control data, it will know to transmit only over the portion of the RB used for non-control data transmissions. Rate matching will then be performed on the non-control data that needs to be transmitted and the non-control data will be transmitted only over a portion of the RB. The second portion of the RB will be used for normal control data transmissions by other UEs.

Abstract translation: 当UE（102）确定需要发送非控制数据时，UE将接收包括标识用于UE的传输的资源块（RB）的信息的许可。 如果UE确定RB也用于发送控制数据，则它将知道仅在用于非控制数据传输的RB的部分上进行传输。 然后对需要发送的非控制数据执行速率匹配，并且非控制数据将仅在RB的一部分上传输。 RB的第二部分将用于其他UE的正常控制数据传输。
