Time slot resource allocation method and device

Abstract

The invention discloses a time slot resource allocation method and device. The method comprises the following steps: a network side measures the signal receiving qualities of time slots used by a user terminal and calculates the quantity of the time slots the signal receiving qualities of which are higher than a set threshold; the network side calculates the size of a transmission block when a first time slot resource allocation mode is allocated to the user terminal according to the calculated quantity of the time slots the signal receiving qualities of which are higher than the set threshold; and the network side calculates the size of a transmission block when a second time slot resource allocation mode is allocated to the user terminal according to the quantity of all time slots used by the user terminal; and the network side selects a time slot resource allocation mode and a time slot resource corresponding to the time slot resource allocation mode according to the calculated sizes of the transmission blocks of the first time slot resource allocation mode and the second time slot resource allocation mode. By adopting the method and device disclosed by the invention, the wireless resource utilization ratio can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a time slot resource allocation method and a device thereof. Background technique [0002] At present, the rapid development of global mobile data services, the continuous increase of business applications that have high requirements for uplink data rate and delay performance, and the HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) technology The wide application of the technology has greatly promoted the demand for HSUPA technology, and has become the main driving force for the commercial use of HSUPA (High Speed ​​Uplink Packet Access) technology. [0003] HSUPA is a technology that adaptively changes the modulation mode and coding rate according to channel conditions, that is, combined with power control, UE (User Equipment, user equipment, also known as user terminal) according to the resource parameters authorized by the ...

AI Technical Summary

Problems solved by technology

[0006] (1) The power control of E-PUCH (E-DCH uplink physical channel, where E-DCH is the English abbreviation of Enhanced Dedicated Channel, which is expressed in Chinese as Enhanced Dedicated Channel and is the transmission channel of HSUPA) is performed in units of users, Without subdividing time slots, the average value of multi-slot SNR (Signal-to-Noise Ratio) is used for power control. Due to the scheduling of time slots with poor reception quality, user terminals are required to increase transmission power, which increases system interference and further reduces available power resources. Reduced, the transmission block becomes smaller, and the rate drops

[0007] (2) Due to poor reception quality and time slot scheduling, the data of the scheduled subframe cannot be decoded correctly, which increases the number of retransmissions and reduces the upload rate

[0008] (3) It is impossible to take advantage of the higher code rate of high-reception quality time slots, and it is impossible to increase the data bits that can be carried by unit resources, which reduces the utilization of wireless resources.
