Problems solved by technology

[0005] In the HSDPA system, the NB allocates a certain number of time slot code channel resources to the UE each time, and adjusts the number of time slot code channel resources allocated to the UE in real time according to the RTBS ​​fed back by the UE, because the air interface or the UE itself Processi

Embodiment Construction

[0022] Embodiments of the present invention provide a time slot code channel resource allocation method, device and equipment, which are used to reduce the rate of change of the number of time slot code channel resources allocated to UEs, thereby reducing air interface BLER and improving system throughput. In the embodiment of the present invention, the HSDPA system is taken as an example for introduction, and of course it can also be applied to the time slot code channel resource allocation process of other systems. Wherein, one scheduling period is one TTI, which corresponds to what is usually called one-time scheduling.

[0023] First, the slot code channel resource allocation algorithm proposed by the embodiment of the present invention is introduced. The algorithm determines the slot code channel resource allocation scheme adopted according to the number of schedulable UEs in the current scheduling period. First, the relevant parameters involved in the algorithm are descri...

Abstract

The invention relates to a time-slot code channel resource allocation technology which belongs to the technical field of mobile communication. The invention provides a method, a device and equipment for time-slot code channel resource allocation, which are used for reducing the variance ratio of the time-slot code channel resource quantity allocated to a UE. The method comprises the following steps: the quantity of the schedulable UE in the dispatching cycle is determined;, when being available in the current dispatching cycle, the time-slot code channel resources allocated by the schedulable UE in the previous dispatching cycle are determined as the time-slot code channel resources allocated by the schedulable UE when the quantity of the schedulable UE is smaller than or equal to the set value; and when the quantity of the schedulable UE is larger than the set value, AMC time slots and AMC code channels corresponding to the schedulable UE are calculated, and when the fact that a residual assignable code channel exists in each AMC time slot which corresponds to the schedulable UE is determined, the time-slot code channel resources allocated for the UE are AMC time slots, AMC code channels and residual assignable code channels.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a time slot code channel resource allocation technology. Background technique [0002] The 3rd Generation Partnership Project (3GPP) Release 5 (R5) version introduces the High Speed ​​Downlink Packet Access (HSDPA) technology, and the downlink data is sent through the base station (NodeB, NB) to the Realization of fast scheduling of different user equipments (User Equipment, UE). [0003] In HSDPA technology, the logical channel of the transport layer, the High Speed ​​Downlink Shared Channel (HS-DSCH), is used to transmit the downlink data sent to the UE; the HS-DSCH is mapped to the High Speed ​​Physical Downlink Shared Channel (High Speed ​​Packet On the Downlink Shared Channel (HS-PDSCH), the spreading factor (SF) of the channel code used by each HS-PDSCH is fixed at 16, that is, the HS-PDSCH can be divided into 16 parallel transmission code channels for downlin...
