Abstract: A method and apparatus for decoding data is provided herein to show how to turbo decode LDPC codes that contain a partial dual diagonal parity-check portion, and how to avoid memory access contentions in such a turbo decoder. During operation, a decoder will receive a signal vector corresponding to information bits and parity bits and separate the received signal vector into two groups, a first group comprising signals corresponding to the information bits and one or more parity bits, a second group comprising a remainder of the parity bits. The first group of received signals is passed to a first decoder and the second group of received signals is passed to a second decoder. The decoders are separated by an interleaver and a deinterleaver. Iterative decoding takes place by passing messages between the decoders, through the interleaver and the deinterleaver, and producing an estimate of the information bits from the output of the first decoder.

Abstract: A method and apparatus for pilot signal transmission is disclosed herein. In particular, a pilot transmission scheme is utilized where pilot sub-carrier bandwidth differs from data sub-carrier bandwidth. Because some user's data sub-carriers will no longer have the user's pilot sub-carriers adjacent to them, the set, or pattern of sub-carriers used by the pilot blocks changes at least once in a burst. Changing the pilot block pattern (the set of occupied pilot block sub-carriers) at least once in the burst serves to increase the frequency proximity of occupied data sub-carriers to occupied pilot sub-carriers in the burst.

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。
