Embodiment Construction

[0027] The core idea of ​​the present invention is that the terminal reports the bearer channel capability of time slot 0 (TS0) to the network side, and the network side allocates downlink resources to the terminal according to the bearer channel capability 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. There are many ways to notify the system side of the bearer capacity of TS0 on the uplink channel, such as the terminal capability reporting method and the RRC (radio resource control) connect...

Abstract

The invention provides a downlink resource allocation method. The method comprises the following steps of: receiving the time slot 0 bearer channel capability submitted by a terminal at the network side, allocating downlink resources for the terminal according to the time slot 0 bearer channel capability; allocating downlink resources configured on a time slot 0 and / or a non-time slot 0 for the terminal by the network side if the terminal supports a time slot 0 bearer channel; and allocating downlink resources configured on the non-time slot 0 for the terminal by the network side if the terminal does not support the time slot 0 bearer channel. The invention also provides a downlink resource allocation system. The method and the system provided by the invention allocate the resources according to the time slot 0 capability of the terminal, avoid the data receiving error of the terminal, have little influence on the resource allocation process and are simple to implement.

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...
