Scheduling method and transmitting method of uplink data, base station and user equipment

Abstract

The embodiment of the invention discloses a scheduling method and a transmitting method of uplink data, a base station and user equipment, relating to the technical field of communication and being invented for being capable of dynamically distinguishing continuous frequency domain resource allocation indication and non-continuous frequency domain allocation indication in real time without increasing information bit number of original scheduling information. The scheduling method of the uplink data transmission comprises the steps of: determining a configuration manner of a frequency hopping information domain; informing the user equipment of the configuration manner of the frequency hopping information domain; generating scheduling information for indicating the user equipment for carrying out uplink data transmission according to the configuration manner of the frequency hopping information domain; and sending the scheduling information to the user equipment. The embodiment of the invention can be used in an enhanced long-term evolution technology.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a scheduling method, transmission method, base station and user equipment for uplink data. Background technique [0002] With the growth of demand and the advancement of technology, wireless communication systems require higher and higher data rates. In addition to the need to increase the transmission bandwidth, the spectral efficiency also needs to be greatly increased. In order to improve spectrum efficiency, the uplink of the Long Term Evolution Advanced (LTE-A, Long Term Evolution Advanced) system introduces non-contiguous resource allocation, that is, multiple non-contiguous frequency bands can be allocated within a component carrier bandwidth, which is the same as the Long Term Evolution (LTE-A) , LTE) Release 8 (Rel-8, Release 8) compared with continuous frequency domain resource allocation, can obtain greater frequency domain selective scheduling gain....

Problems solved by technology

[0005] In the process of realizing the above distinction between DCI format 0 and DCI format 0A, the inventors found that at least the following problems exist in the prior art: in the first distinction method, DCI format 0A and DCI format 0 cannot be dynamically distinguished from time to time, when the uplink When the system bandwidth is greater than the system bandwidth of the downlink paired with it, there is no redundant information bit in DCI format 0, so DCI format 0A and DCI format 0 cannot be distinguished

In the second way, increasing the number of information bits will increase the number of blind decoding times of PDCCH in the common search space, which will affect the performance of the system.
