摘要:
A method and apparatus for compiling a protocol data unit (PDU) having a predetermined length from at least one data block for transmission in a wireless communication system. At least one data block is designated for transmission. The data block is first stored in a memory. A data block information list and a data block address list are generated for the data block. The data block information list contains the length of the data block which is to be included within the PDU and the data block address list contains the memory address of data block which is to be included in the PDU. The PDU is then compiled utilizing the data block information list and the data block address list when the PDU is ready for transmission.
摘要:
A method for processing enhanced dedicated channel (E-DCH) data in a wireless transmit/receive unit (WTRU) includes sending two messages. A first message is sent from a physical layer to a medium access control (MAC) layer, and triggers MAC layer processing of E-DCH data. A second message is sent from the MAC layer to the physical layer, and enables the physical layer to compute control parameters for physical layer processing of the E-DCH data before the MAC layer processing of the E-DCH data is completed.
摘要:
A method and apparatus for efficient operation of an enhanced dedicated channel (E-DCH) are disclosed. A physical layer processing includes computation of various control parameters followed by actual processing of the data to be transmitted. In accordance with the present invention, the computation of the control parameters is performed asynchronously from the associated data operation. A medium access control (MAC) layer provides information needed for computation of the control parameters to the physical layer as early as possible, while the data is being processed in parallel. The provided data includes a hybrid automatic repeat request (H-ARQ) profile, a transport block size, power offset, or the like. By sending this data to the physical layer before MAC-e processing is complete, the latency constraint can be significantly relaxed.
