Embodiment Construction

[0019] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0020] method embodiment

[0021] According to an embodiment of the present invention, a MAC layer scheduling method of HSUPA is provided, which can allocate time slots, code channels, and power to multiple users at the same time.

[0022] Because uplink users can occupy multiple time slots in one TTI, the number of available code channels in different time slots is different; at the same time, because the existing interference in different time slots is different, the allowable transmit power is also different . But the same user can only have one SF (spreading factor) and transmit power in one TTI. In view of the above conditions and constraints, the TD-SCDMA HS...

Abstract

The invention provides a dispatching method for a media access control layer with high-speed uplink packet access and a system thereof. The method comprises the steps that: Step S102. the priority levels of users applying for dispatching are determined and ranking is carried out according to the priority levels; Step S104. combination is carried out to available slot times and code channels so as to cause various combinations to have the same spreading factor and code channel in different slot times; Step S106. the combination of slot times and code channels that can transmit reported caching data in a maximum manner is selected for users with the highest priority level and the minimum TBS that can cache transmission in a maximum manner is selected from the TBS of the users with the highest priority level; Step S108. as for the rest code channel resources, users with the priority level following the highest level are selected to be the users with the highest priority level to carry out authorization assignment, and Step S106 is carried out until that dispatching user number which the system can support simultaneously is achieved or resource allocation is finished.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, relates to HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) in TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) wireless communication system The MAC (Media Access Control, Media Access Control) layer scheduling method and system of the present invention. Background technique [0002] In the third generation (3G) mobile communication system, in order to provide higher rate uplink packet services and improve spectrum utilization efficiency, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced the HSUPA feature, that is, the uplink enhanced feature. The main purpose of HSUPA is to reduce the scheduling time, and move the scheduling function from RNC (Radio Network Controller, radio network controller) to Node B (Node B), which can ...
