Embodiment 1

[0028] This embodiment includes the following steps:

[0029] First, reduce the power by one step. The appropriate value of the power reduction step here is 1dB, and judge whether the resource meets the actual amount of information to be sent:

[0030] If it is not satisfied, it means that the previous power is the minimum power requirement to meet the actual amount of information to be sent, and the power needs to be backed up by one step to return to the previous power value, and the obtained power and corresponding code channels are allocated to users ;

[0031] If it is satisfied, then reduce the number of code channels by one step, where the value of the code channel number reduction step is preferably 1 code channel, and judge whether the resource meets the actual amount of information to be sent:

[0032] If it is not satisfied, it means that the previous number of code channels is the minimum number of code channels to meet the actual amount of information to be sent....

Embodiment 2

[0040] This embodiment includes the following steps:

[0041] First reduce the number of code channels by one step, and judge whether the resource meets the actual amount of information to be sent:

[0042] If it is not satisfied, it means that the previous number of code channels is the minimum number of code channels to meet the actual amount of information to be sent. number and the corresponding power allocated to users;

[0043] If it is satisfied, then reduce the power by one step to judge whether the resource meets the actual amount of information to be sent:

[0044] If it is not satisfied, it means that the previous power is the minimum power requirement to meet the actual amount of information to be sent, and the power needs to be backed up by one step to return to the previous power value, and the obtained power and corresponding code channels are allocated to users .

[0045] The power and code channels obtained by performing the above steps are the final resour...

Abstract

When the real quantity of user's waiting for sent message is less than the max quantity of message allowing the user to send, then reduces crossly step by step the power and the number of the hi-speed down-going share code channel, configures the power and the code channel number matching to the real quantity of user message. This scheme both fulfills user-sending requirement and balances the resource consumption of the hi-speed down-going share channel. The saved resource may be dispatch to other users. This ensures the max data throughput in whole cell.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a technology for allocating high-speed downlink shared channel resources. Background technique [0002] The full name of HSDPA is High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access), which is an important feature of the fifth version of WCDMA technology. ) and a series of key technologies to achieve downlink high-speed data transmission. [0003] In the WCDMA system, the introduction of HSDPA adds three channels, which are the HS-PDSCH channel (High Speed ​​Physical Downlink Shared Channel) for transmitting data information in the downlink, and the HS-SCCH for transmitting downlink control information. channel (High Speed ​​Shared Control Channel, high-speed shared control channel), and an HS-DPCCH channel (High Speed-Dedicated Physical Control Channel, high-speed dedicated physical control channel) for transmitting uplink feedback information. [000...
