Embodiment 1

[0069] This preferred embodiment is described by taking an LTE system applying the method and device for transmitting uplink data proposed by the present invention as an example.

[0070] Assume that the configured system bandwidth of the system is 5MHz, and there are 25 RBs (each RB has a corresponding index, the minimum value is 0, and the maximum value is 24) for data transmission. In a downlink data transmission, the base station notifies the terminal of the available RB resource index set through the downlink channel, which is recorded as Valid_RBset={0,1,2,3,4,5,6,7,8,9,15,16,17 ,18,20,21,22,23,24}, indicating that in the system RB, all indexes in Valid_RBset are available, otherwise they are not available. The index of each value in Valid_RBset is recorded as Valid_RBsetIdx={0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18} . Wherein, the value in Valid_RBset indicates that the system RB corresponding to the index can be used for data transmission, otherwise it cannot b...

Abstract

The invention discloses a data transmission and data processing method and device. The data transmission method comprises the steps of receiving a scheduling message, wherein the scheduling message carries resource RB resource information for data transmission, and RB resources corresponding to the RB resource information are continuous; determining the RB resource for data transmission according to the RB resource information and pre-received currently available RB resources; and carrying out data transmission according to the determined RB resource. By adopting the data transmission method disclosed by the invention, the problem of low resource utilization rate in data transmission in the related art is solved, and an effect of carrying out the data transmission via the RB resources flexibly is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission and data processing method and device. Background technique [0002] In the uplink of the Long Term Evolution (LTE for short) system, the transmission mode of the Physical Uplink Shared Channel (PUSCH for short) adopts the Orthogonal Frequency Division Multiple Access (OFDMA for short) technology. [0003] Before the LTE version 10, on the PUSCH, each user used a continuous time-frequency domain resource (ResourceElement, RE for short) allocated by the system as its own frequency band for data transmission and pilot transmission. The time-domain index of the RE is a symbol index, and the frequency-domain index is a subcarrier index, and data and pilots occupy symbols with different indexes and subcarriers with the same index. The discontinuous RB allocation mode is introduced in the LTER10 version. In the R10 protocol, a continuous RB is called a cluster (c...
