Method and apparatus for scheduling high speed down packet access service

Abstract

The invention discloses a dispatching method of the high-speed downgoing packet accessing service and a device thereof. The method comprises: determining a plurality of priority queues which need to be simultaneously transmitted; taking out the data from the priority queues and cascading the data blocks with different sizes from the same queue and the data blocks from different queues to generateMAC-hs PDU; storing MAC-hs PDU in a HARQ cache and distributing the HSDPA resource to UE; constructing the dispatching information of HS-SCCH and sending to UE; transmitting MAC-hsPDU to user equipment when the HSDPA resource which is distributed to UE is valid. The device comprises: a UE determination unit, a HARQ entity and priority queue determination unit; a MAC-hs PDU generation unit; a HSDPA resource distribution unit; a dispatching information construction unit; and a data transmission unit. The method or the device can realize that a plurality of priority queues can be transmitted by only one HARQ process during one dispatching.

Description

technical field [0001] The present invention relates to the third-generation mobile communication technology, in particular to a method and device for scheduling (HSDPA, High Speed ​​Downlink Packet Access) high-speed downlink packet access services. Background technique [0002] In the Release5 version of 3GPP, HSDPA technology was proposed. The main feature of this technology is to adopt adaptive modulation and coding technology, hybrid request retransmission mechanism (HARQ), and resource sharing mechanism in order to achieve greater capacity, reduce delay and achieve higher peak rate. Using HSDPA technology, different users can share a group of resources at the same time. [0003] The high-speed data service bearer of HSDPA is mainly transmitted through a high-speed downlink shared channel (HS-DSCH, High Speed ​​Downlink Shared Channel). HS-DSCH is a dedicated channel for HSDPA. The HS-DSCH is a transport channel, and the physical channel to which it is mapped is call...

Problems solved by technology

In this solution, the same UE needs to monitor multiple HS-SCCHs at the same time and return responses on different HS-SICHs, which obviously leads to a decrease in resource utilization because only a small amount of control is transmitted on HS-SCCHs and HS-SICHs. information, therefore, it is wasteful to configure multiple HS-SCCH and HS-SICH for one UE

In addition, because different services are scheduled separately, the High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed ​​Physical Downlink Shared Channel) must also be strictly separated, which may lead to waste of HS-PDSCH resources

[0021] However, in 3G applications, due to the diversification of services, it is very likely that one UE has multiple services carried on HSDPA at the same time. Using the prior art HSDPA scheduling method is obviously not conducive to multiple services from the same UE The sharing of physical resources, therefore, how to better schedule multiple service queues of a UE at the same time has become a practical problem
