Embodiment 1

[0070] Embodiment 1 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as figure 1 shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id, C / T, LI.

Embodiment 2

[0071] Embodiment 2 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as figure 2 shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). And limit that only one logical channel is allowed to be mapped to the transport channel. The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id and LI.

Embodiment 3

[0072] Embodiment 3 provides a structure of the MAC PDU used on the multiplexed forward access channel, such as image 3 shown. In the layer 3 signaling during the establishment process, the logical channel category of the bearer has been agreed, and the terminal identification number can only use the type of CRNTI (Cell Radio Network Temporary Identification Number). And all the media access control service data units of different terminals multiplexed in one MAC PDU have the same length, and indicate the specific length. The media access control header includes N (the value of N is k) and k groups of sub-headers, corresponding to k media access control service data units, and padding is used at the end to align them. The subheader includes UE-Id, C / T.

Abstract

The invention provides the structure device of the media access control protocol data unit of downlink transfer channel used under CELL-FACH state, which comprises a merging module and a sending module. The merging module is used for merging the data packets sending to different terminals at the same time into a media access control protocol data unit; the sending module, is used for sending a media access control protocol data unit through downlink transfer channel which is used under CELL-FACH state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a construction device for multiplexing Media Access Control (MAC) data units in a wireless communication system, and in particular to a multiplexed forward access Means for constructing the Medium Access Control Protocol Data Unit (MAC PDU) used on the channel. Background technique [0002] The two basic modes of operation of a terminal are idle mode and connected mode. The connection mode can be further divided into different states: URA_PCH state (URA Paging Channel, access network registration area paging channel state, hereinafter referred to as URA_PCH), CELL_PCH state (CELL Paging Channel, cell paging forward access channel state, hereinafter referred to as CELL_PCH), CELL_FACH state (CELL Forward Access Channel, cell forward access channel state, hereinafter referred to as CELL_FACH), CELL_DCH (CELL Dedicated Channel, cell dedicated channel state, hereinafter referred to...
