Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0031] It can be seen from Shannon's formula C=Blog2(1+S / N), when the system signal-to-noise ratio and coding technology are stable, only by increasing B can the channel capacity be improved. where C is the channel capacity, B is the channel bandwidth (Hz), S is the signal power (watts), and N is the noise power (watts).

[0032] Small bandwidth scenarios have higher requirements for uplink rates. In order to effectively utilize bandwidth resources, the present invention adopts a method of not configuring or using PUCCH resources, saving PUCCH resource overhead, and using the vacated RB resources for PUSCH, thereby The uplink rate can be greatly improved. As shown in Table 2, when PUCCH resources are not configured, the uplink rate can reach 1.31...

Abstract

The invention discloses a method for improving an uplink rate of an LTE system. The method comprises the following steps: judging whether a terminal has been allocated with an uplink resource for sending uplink shared channel UL-SCH data in a current sub-frame; if the terminal is not allocated with the uplink resource for sending the UL-SCH data in the current sub-frame, constructing, by a base station, uplink pre-scheduling authorization pre UL grant and sending the same to the terminal, not allocating a physical uplink control channel PUCCH resource to the terminal, and providing a corresponding resource block RB resource for a physical uplink shared channel PUSCH for use. By application of the technical scheme provided by the invention, the uplink rate of the LTE system can be improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a method for increasing the uplink rate of an LTE system. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the role of PUCCH (Physical Uplink Control Channel, physical uplink control channel) is briefly described as follows: [0003] The terminal needs to send necessary uplink L1 / L2 control information to support uplink and downlink data transmission. Uplink L1 / L2 control information (Uplink Control Information, UCI) includes: [0004] · SR (Scheduling Req, scheduling request): used for the terminal to request uplink shared channel (UL-SCH) resources from the base station. [0005] HARQ ACK / NACK (Hybrid Automatic Repeat Request Acknowledgment / Non-Acknowledgment): Perform HARQ acknowledgment for downlink data sent on PDSCH (Physical Downlink Share Channel, Physical Downlink Share Channel). [0006] CSI: Channel S...
