Problems solved by technology

When the length of the data to be transmitted corresponding to the UE is not enough to fully use the allocated available PDSCH resources, it may result in a maximum additional waste of Nc1-1 code channel blocks
[0012] In summary, the implementation of the prior art seriously wastes available PDSCH resources, and cannot use the TFRI field to indicate all available PDSCH resources

Embodiment Construction

[0058] In the embodiment of the present invention, through detailed traversal of all code channels and time slots, all available PDSCH resources that can be indicated by the TFRI field are obtained, and then the available PDSCH resources are selected and indicated to the UE through the TFRI field, so as to realize the allocation of available PDSCH resources to the UE .

[0059] In this embodiment, a code channel block refers to a rectangle formed by a code channel and a time slot in a Cartesian orthogonal coordinate system, which is a division of the network from the perspective of time slots and code channels. A resource block refers to one or more code channel blocks conforming to the structure of the TFRI field, and is a division of network resources from the perspective of code channel blocks. The resource allocation granularity indicates the minimum length of allocated resources in a resource allocation process (the length refers to the number of bits that can be carried)...

Abstract

The invention discloses a method for allocating high speed physical down link shared channel resource for utilizing the high speed physical down link shared channel resource effectively. The method comprises: acquiring the code channel block allowed to carry the high speed physical down link shared channel (HS-PDSCH) resource in system; conforming the available HS- PDSCH resource block, which includes one or several code channel blocks in one time slot or includes one or several continuous code channels on several time slots, made up of the code channel blocks in different combining mode; and selecting an available HS-PDSCH resource block among the confirmed available HS-PDSCH resources to allocate to the current user equipment needing available HS-PDSCH resource. The invention further discloses an apparatus.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for allocating physical downlink shared channel resources. Background technique [0002] Currently, the 25.858 protocol in Release 5 of the 3rd Generation Partnership Project (3GPP) stipulates that in a High-Speed ​​Downlink Packet Access (HSDPA) system, The resources are allocated by the radio network controller (Radio Network Controller, RNC), and the base station (Node B, NB) controls the transmission format resource indication ( The Transport Format Resource Indicator, TFRI) field indicates to each user equipment (User Equipment, UE) the available resources on the High Speed ​​Downlink Shared Channel (High Speed ​​Downlink Shared Channel, HS-DSCH), including the time slot allocated to the UE ( TimeSlot, TS) and code channel (Code). The UE needs to monitor the time slot and code channel indicated by the TFRI field, so as to correctly parse the HS-DSCH data. [...
