    • Example methods and apparatus for communicating encoded data blocks in wireless communication systems are disclosed. In one example embodiment, a method for receiving an encoded data block includes receiving a data transmission including a subset of a plurality of bits of the encoded data block. The example method also includes receiving a first control signal indicating whether the received subset is a first received subset associated with the encoded data block or whether one or more subsets were previously received for the encoded data block. The example method also further includes receiving a second control signal, the second control signal having a first state and a second state. In the example method, the first state of the second control signal indicates that the received subset includes a first predefined subset of the plurality of bits of the encoded data block and the second state of the second control signal indicates that the received subset includes one of a plurality of other predefined subsets of the plurality of bits of the encoded data block. In this example embodiment, determining which of the other predefined subsets is included in the received subset is based on one or more system parameters of the wireless communication system. Further in this example, the state of the second control signal is selectable between its first state and its second state on a data transmission by data transmission basis, regardless of whether or not one or more subsets of the encoded data block were previously received.
    • 公开了用于在无线通信系统中传送编码数据块的示例性方法和装置。 在一个示例实施例中,用于接收编码数据块的方法包括接收包括编码数据块的多个比特的子集的数据传输。 示例性方法还包括接收指示所接收的子集是否是与编码数据块相关联的第一接收子集的第一控制信号,或者是否先前为编码数据块接收到一个或多个子集。 该示例方法还包括接收第二控制信号,第二控制信号具有第一状态和第二状态。 在示例性方法中,第二控制信号的第一状态指示接收到的子集包括编码数据块的多个比特的第一预定义子集,第二控制信号的第二状态指示接收到的子集包括 编码数据块的多个比特的多个其它预定义子集。 在该示例实施例中,确定在接收的子集中包括其他预定义子集中的哪一个是基于无线通信系统的一个或多个系统参数。 此外,在该示例中,无论先前接收到编码数据块的一个或多个子集,无论数据传输为基础,第二控制信号的状态都可以在数据传输之后的第一状态和第二状态之间进行选择。

    • Apparatus, methods and computer program products implement HARQ buffer size reduction by storing successfully received blocks of a multi-block signal in a code block buffer and only storing unsuccessfully received blocks of the multi-block signal in the HARQ buffer. As HARQ retransmissions of the signal occur, previous successfully received blocks are discarded. Blocks that were not successfully received in one or more previous signals but are successfully received in a HARQ retransmission are saved in the code block buffer. The process may continue until all blocks of the multi-block signal have been successfully decoded received and stored in the code block buffer. The successfully received blocks of the multi-block signal are then passed to higher layers.
    • 设备,方法和计算机程序产品通过将成功接收到的多块信号的块存储在码块缓冲器中并且仅将多块信号的未成功接收的块存储在HARQ缓冲器中来实现HARQ缓冲器大小的减小。 当发生信号的HARQ重传时,先前成功接收的块被丢弃。 在一个或多个先前信号中未成功接收但在HARQ重传中成功接收的块被保存在码块缓冲器中。 该过程可以继续,直到多块信号的所有块已被成功解码,并被存储在代码块缓冲器中。 成功接收的多块信号的块然后被传递到更高层。
