Embodiment Construction

[0199] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0200]Subframes: In the time domain, LTE transmissions are organized into radio frames with a length of 10ms. Each radio frame is divided into 10 subframes with the same size and a length of 1ms. Each subframe contains two time slots with the same size. A time slot is composed of a certain number of Orthogonal Frequency Division Multiplexing (English: Orthogonal Frequency Division Multiplexing, referred to as: OFDM) symbols including a cyclic prefix. If it is a conventional cyclic prefix, each time slot includes 7 OFDM symbols; If the cyclic prefix is ​​extended, each time slot includes 6 OFDM symbols, hereinafter referred to as symbols.

[0201] Please refer to figure 1 , which shows a block diagram of an uplink data sending device p...

Abstract

An embodiment of the present invention provides an uplink data sending device and method, which relate to the communication field, and the method includes: configuring the same uplink contention resource to multiple UEs through an eNB, m≥2; the UE uses the SR symbol in the uplink contention resource Send SR to eNB; send uplink data to eNB through shared symbols in uplink contention resources; eNB receives SR sent by UE through SR symbols in uplink contention resources; eNB receives uplink data sent by UE through shared symbols in uplink contention resources. Solve the problem that when multiple UEs send uplink data to the eNB on the same uplink contention resource and cause contention conflicts, the uplink contention resource is completely wasted; when the eNB fails to receive the uplink data sent by the UE through the uplink contention resource , it is still possible to determine which UE has sent uplink data according to the successfully received SR.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink data sending device, receiving device and method. Background technique [0002] In the long-term evolution (English: Long Term Evolution, referred to as: LTE), the user equipment (English: UserEquipment, referred to as: UE) usually sends an uplink to an evolved base station (English: Evolved Node B, referred to as: eNB) based on a scheduling transmission method. data. [0003] When the UE needs to send uplink data, the UE first sends an uplink scheduling request (English: SchedulingRequest, SR for short) to the eNB; the eNB configures an uplink scheduling grant (English: Up Link Grant, UL Grant for short) to the UE according to the SR , the UL Grant is used to configure uplink transmission resources for the UE. When the UE correctly decodes and obtains the UL Grant, it sends uplink data to the eNB according to the uplink transmission resources configured by the eNB. ...
