Embodiment Construction

[0027] The core idea of ​​the present invention is that the terminal reports the bearer channel capacity of time slot 0 (TS0) to the network side, and the network side allocates downlink resources to the terminal according to the bearer channel capacity of time slot 0 of the terminal.

[0028] The present invention will be described below by taking HSDPA resource allocation as an example, but the present invention is not limited thereto.

[0029] The present invention provides a downlink resource allocation method, including:

[0030] Step S1, the terminal (UE) reports the bearer channel capability of time slot 0 to the network side;

[0031] Among them, the channel capability of the time slot 0 bearer channel refers to whether the terminal supports the bearer channel in time slot 0, and there are many ways to notify the system side of the bearer capacity of TS0 on the uplink channel, such as the terminal capability report method, RRC (radio resource control) connection method...

Abstract

The present invention provides a method for downlink resource allocation, which includes: a network side receives Time Slot 0 (TS0) bearer channel capability reported by a terminal, and allocates downlink resources for said terminal according to said TS0 bearer channel capability, wherein, if said terminal supports TS0 bearer channels, said network side allocates the downlink resources allocated in TS0 and / or not in TS0 for said terminal; if said terminal does not support TS0 bearer channels, said network side allocates the downlink resources allocated not in TS0 for said terminal. The present invention also provides a system for downlink resource allocation. By performing the resource allocation according to the terminal TS0 capability, the method and system of the present invention avoid the terminal data receiving error, influence little on the resource allocation process, and are easily achieved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a downlink resource allocation method and system. Background technique [0002] An important feature of the third-generation mobile communication system is the unbalanced traffic volume of the uplink and downlink. The traffic volume of the downlink is generally greater than that of the uplink. In response to this requirement, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced a High Speed ​​Downlink Packet Access (HSDPA: High Speed ​​Downlink Packet Access) feature in the 3G specification. In the HSDPA feature, by introducing Adaptive Modulation and Coding (AMC: Adaptive Modulation and Coding), Hybrid Automatic Retransmission Request (HARQ: Hybrid Automatic Retransmission Request) technology and related technologies to reduce network processing delay, to provide higher rate The downlink packet service rate improves spectrum util...
