Description

Data transmission method and device and user equipment
Technical Field
The present invention relates to the field of information technologies, and in particular, to a method and an apparatus for transmitting data, and a user equipment.
Background
In a Frequency Division multiplexing (FDD) system of the Third Generation Partnership Project (3 GPP) Long Term Evolution (LTE), one radio frame includes 10 subframes (sub-frames), one subframe occupies 1 millisecond (ms) and is divided into two slots (slots), and one resource block occupies one slot in the time domain. In order to obtain a gain of frequency diversity, a frequency hopping technique is introduced in 3GPP, and the technique includes: inter-sub-frame hopping and inter-sub-frame and intra-sub-frame hopping.
At present, in a frequency hopping method, a user equipment with a Transmission time interval of 1ms (hereinafter, referred to as Transmission time interval, TTI) uses a frequency hopping scheme of type1 or type2 to perform frequency hopping between subframes or subframes plus one another, so that a corresponding Physical Resource Block (PRB) performs data Transmission after frequency hopping.
However, when the user equipment of 1ms tti determines the PRB resource block for data transmission by using a frequency hopping method, because the user equipment of 1ms tti transmits the PRB resource, the minimum resource block for data transmission is a resource block pair, however, when the user equipment of 1ms tti actually transmits data, the resource of a resource block pair may not be used, so that the utilization rate of the transmission resource is low.

Compared with the current 1ms TTI user equipment determining the PRB resource block for data transmission in a frequency hopping mode, in the embodiment of the invention, the 0.5ms TTI user equipment determines the index of the PRB resource according to the index of the VRB resource indicated in the authorization indication information sent by the base station and in the frequency hopping mode, so that the user equipment can perform data transmission on the PRB resource corresponding to the index, and when the user equipment of the 0.5ms TTI performs data transmission, the minimum resource of the data transmission is one resource block instead of one resource block pair, so that the user equipment can perform data transmission on the resource block, and thus the utilization rate of the transmission resource can be improved.
Further, the embodiment of the present invention provides a user equipment supporting 0.5ms tti, where the user equipment determines the index of the PRB resource in a subband 1 manner, and only has mirroring without subband offset, so that the frequency hopping regions of the user equipment of 0.5ms tti and the user equipment of 1ms tti can be separated. Thereby reducing the collision probability; when the base station transmits data to the user equipment with the TTI of 0.5ms, the residual resources are allocated to the user equipment with the TTI of 1ms for dynamic scheduling, so that the resources can be fully utilized, and the waste of the resources can be avoided.

For the embodiment of the present invention, because the frequency hopping types selected by the user equipment are different and the frequency hopping information of the user equipment in the SIB message is different, the user equipment determines the index of the PRB resource in different ways according to the frequency hopping information of the user equipment indicated in the authorization indication, where the frequency hopping information includes: frequency hopping pattern, number of subbands, and frequency hopping offset.
Specifically, the frequency hopping pattern may include: and inter-sub-frame frequency hopping in the sub-frame, wherein the number of the sub-bands can be divided into the condition that the number of the sub-bands is 1 or more than 1, and the frequency hopping offset is used for representing RB resources occupied by PUCCH.

For example, if the index of the VRB resource indicated in the grant indication received by the ue is 2, the index of the PRB resource corresponding to the ue in the first slot of each subframe in the ue is 2.
602. If the grant indication information indicates that the time slot of the current data transmission of the user equipment is the second time slot, the frequency hopping Type of the user equipment is Type1, and the frequency hopping mode of the user equipment is inter-subframe plus intra-subframe frequency hopping, the user equipment determines that the index of the PRB resource is the index of the PRB resource obtained after frequency hopping is performed with the index of the VRB resource indicated in the grant indication information as a reference.

For example, if the index of the VRB resource indicated in the current transmission grant instruction is 1, the index of the PRB resource, which is the frequency domain location where the user equipment performs the current data transmission, is 1.
704. If the current transmission times are odd numbers and the frequency hopping Type corresponding to the user equipment indicated in the authorization indication information is Type1, the user equipment determines the index of the PRB resource as the index of the PRB resource obtained after frequency hopping by taking the index of the VRB resource indicated in the authorization indication information corresponding to the current transmission as a reference.
For the embodiment of the present invention, if the frequency hopping Type indicated in the received authorization indication information is Type1 and the current transmission frequency currently determined by the user equipment is an odd number when the user equipment performs data transmission this time, the index of the PRB resource for which the user equipment performs data transmission currently is the index of the PRB resource obtained after frequency hopping is performed with the index of the VRB resource indicated in the authorization indication information this time as a reference.

For the embodiment of the present invention, no matter the frequency hopping Type indicated in the grant indication corresponding to the current transmission received by the user equipment is Type1 or Type2, the index of the PRB resource is determined according to the frequency hopping mode of Type 2.

For example, if the number of transmission times of the current data transmission is 3, the index of the VRB resource is 2, and the number of VRBs of the uplink bandwidth is 4, the index of the PRB resource corresponding to the current transmission is 0.
For the embodiment of the invention, no matter the frequency hopping mode is the frequency hopping within the sub-frame plus the frequency hopping between the sub-frames or the frequency hopping between the sub-frames, the index of the PRB resource, namely the position of the user equipment for data transmission is determined according to the frequency hopping mode between the sub-frames, thereby obtaining the gain of the frequency diversity during retransmission.
