Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] refer to figure 1 , briefly explain the multiplexing method accompanying the dedicated physical channel according to the embodiment of the present invention. Such as figure 1 As shown, the multiplexing method includes the following steps: S102, select the multiplexing mode accompanying the dedicated physical channel; S104, determine the state of each accompanying dedicated physical channel according to the number of multiplexing users accompanying the dedicated physical channel; and S106, select The accompanying dedicated physical channel in multiplexed or idle state is assigned to at least one user.

[0018] Wherein, the multiplexing method of the accompanying dedicated physical channel is: keep the transmission format of the accompanying dedicated physical channel unchanged, and make the repetition length of the accompa...

Abstract

The invention discloses a reuse method of associated dedicated physical channels. The reuse method comprises the following steps: a reuse mode the associated dedicated physical channels is selected; states of various associated dedicated physical channels are determined according to the number of reuse users of various associated dedicated physical channels; and the associated dedicated physical channel at the reuse mode or idle mode is selected and distributed to at least one user for use. The reuse method can effectively improve the utilization rate of code resources and improve the capacity and the downlink throughput of a system.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a multiplexing method accompanied by a dedicated physical channel. Background technique [0002] The High Speed ​​Downlink Packet Access (HSDPA) technology was introduced in the Release 5 protocol of Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) technology to improve service downlink throughput. Each HSDPA user needs an uplink associated dedicated physical channel (Associated Dedicated Physical Channel, referred to as A-DPCH) and a downlink associated dedicated physical channel to carry transmit power control (Transmit Power Control, referred to as TPC) bits and other information. Each accompanying DPCH needs to occupy a corresponding channelization code. In the TD-SCDMA wireless access technology, the number of code resources is very limited, and each HSDPA user occupies one channelization code, which will make the code resources becom...
