Method for sending uplink data, base station, user equipment and communication network

Abstract

The embodiment of the invention discloses a method for sending uplink data, a base station, user equipment and a communication network. The method includes the steps that the base station is used for dividing an uplink data channel into a plurality of uplink resource blocks, and all the uplink resource blocks are in mutual orthogonality; the base station generates a first notification message which is used for indicating downlink control channels corresponding to all the uplink resource blocks and determined by the base station; the base station sends the first notification message to the user equipment so that the user equipment can monitor the downlink control channels so as to select a target uplink resource block used for sending uplink data, and the uplink data are sent through the target uplink resource block. In the embodiment, due to the fact that the uplink data channel is divided into the uplink resource blocks by the base station, the sending method can well support small data packages so that when network loads are light, high efficiency can be achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method for sending uplink data, a base station, user equipment and a communication network. Background technique [0002] The current wireless communication system mainly adopts an uplink data transmission method based on central node centralized scheduling to send data, and this kind of transmission method is mainly used in some cellular communication systems, such as the LTE system. [0003] However, in the above-mentioned system, there are random access resources for user equipment to access. Since the number of users that can be supported by the random access resources is generally large, the method described above can greatly reduce the number of users. The impact of unexpected services on the network. Moreover, the scheme is relatively complicated, and the overhead is large, and the efficiency is low when the amount of data to be sent is small and the n...

Problems solved by technology

Moreover, the above-mentioned scheme is relatively complicated, and the overhead is large. When the amount of data sent is small and the network load is very light, the efficiency is low.

[0004] Moreover, the uplink data transmission method in the prior art is not well supported because of its complex implementation, large overhead, low efficiency when the network load is light, and the inability to effectively avoid the impact of a large number of burst services on the network.
