Embodiment Construction

[0240] The following combination figure 1 A method for sending uplink data provided by an embodiment of the present invention is described in detail:

[0241] 101. The base station divides the uplink data channel into multiple uplink resource blocks;

[0242] The base station divides the uplink data channel into multiple independent uplink resource blocks, and makes the uplink resource blocks orthogonal to each other.

[0243] Wherein, the uplink resource block includes time, frequency and code resources.

[0244] Specifically, the base station can divide according to the size of the uplink service data packet sent by the user equipment, and can also divide the uplink resource block according to the actual situation of the current network.

[0245] 102. The base station generates first notification information;

[0246] The base station determines a downlink control channel corresponding to each uplink resource block according to each determined uplink resource block;

[0...

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...
