Embodiment Construction

[0020] In order to solve the problems existing in the prior art, an embodiment of the present invention proposes a data transmission method in consecutive subframes in the same direction. The technical solution is based on the resource utilization information of the previous group of consecutive subframes in the same direction with the same data transmission direction. and the highest resource utilization rate of the non-last subframe in the first group of continuous subframes in the same direction, determine the highest resource utilization rate of the non-last subframe in the current continuous subframes in the same direction; according to the highest resource utilization rate of the non-last subframe in the current continuous subframes in the same direction Utilization rate, determine the highest data transmission volume of each non-last subframe in the current continuous co-direction subframes, and assign corresponding non-last subframes according to the highest data transmi...

Abstract

The invention discloses a method and a device for data transmission of continuous equidirectional subframes, which are used for solving the problem that when data is transmitted in the prior art, the subframes are easy to have heavy loads and generate larger same frequency interference in an adjacent region. The method comprises the steps: the second highest resource utilization of non-end subframes in the current continuous equidirectional subframes is confirmed according to the resource utilization information of a previous set of continuous equidirectional subframes in the same data transmission direction and the first highest resource utilization of the non-end subframes in the first set of continuous equidirectional subframes; the highest data transmission quantity of each non-end subframe in the current continuous equidirectional subframes is confirmed according to the second highest resource utilization, and data is distributed on each non-end subframe of the current continuous equidirectional subframes according to the highest data transmission quantity, and then is data transmission is performed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a data transmission technology of continuous subframes in the same direction. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system is a multi-carrier system in which the physical layer adopts OFDM (Orthogonal Frequency Division Multiplex) technology. Several subcarriers form a resource block, and the resource block is used as a unit for scheduling. The current research on the LTE physical layer technology mainly focuses on two duplex modes: FDD (Frequency Division Duplex, frequency division duplex) and TDD (Time Division Duplex, time division duplex). [0003] For the LTE FDD system, uplink and downlink data occupy different frequency bands, and uplink and downlink data can be transmitted simultaneously. For the LTE TDD system, the uplink and downlink data occupy the same frequency band, and the uplink and downlink data can only be...
