Abstract

The invention discloses a method, a system and a device for allocating resources of HSDPA system, which is used for solving the problem that UE cannot correctly receive HS-DSCH resources in the prior art for allocating resources of the HSDPA system. The method for allocating resources of HSDPA system comprises the following steps: reserving shared control channel HS-SCCH resources of a high speed-downlink shared channel HS-DSCH in a current sub-frame, as well as the HS-DSCH resources of a next sub-frame for a user terminal; and allocating the reserved HS-SCCH resources and the HS-DSCH resources to the user terminal when the interval of initial time slots of the reserved HS-SCCH resources and the HS-DSCH resources is less than two time slots. The invention is used for allocating resources of the HSDPA system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method, system and device of an HSDPA system. Background technique [0002] In order to better meet the demand for network performance caused by the rapid increase of wireless data services, 3GPP Release 5 introduces an important enhanced technology—High Speed ​​Downlink Packet Access (HSDPA). HSDPA uses a shared downlink channel for data transmission, which can achieve higher data throughput. HSDPA is suitable for high-bursty services that require a higher instantaneous downlink rate, and can effectively reduce the degree of data retransmission and transmission delay, especially It is suitable for various data services with asymmetric uplink and downlink, such as video on demand and Internet surfing. [0003] 3GPP Release 5 also formulated the HSDPA technical specification of TD-SCDMA, and defined a high-speed downlink shared channel (HS-DSC...
