Embodiment Construction

[0036] In the LTE communication system, the base station schedules the transmission of downlink data and the transmission of uplink data through DCI in a subframe. For example, for the transmission of downlink data, the base station indicates to the UE the resource configuration information (including the modulation and coding format, the position information of the allocated physical resource block, etc.) of the downlink data transmission in subframe n through the DCI. After the UE decodes its own DCI, Receive data on the physical downlink shared channel according to the resource configuration information contained in it. If the UE can correctly decode the data, the UE will send an acknowledgment character in a certain subframe n+k (k>=4); if the UE cannot decode the data, The UE needs to feed back a negative acknowledgment character.

[0037] The above whole process is a complete data transmission process. Wherein: the length of the subframe is 1 ms, and generally includes ...

Abstract

A base station and a transmission scheduling method thereof, the method comprising: acquiring capability information of the user equipment; wherein: the capability information includes the minimum scheduling delay that the user equipment can support; information scheduled according to its own resources And the capability information of the user equipment, configuring a scheduling delay when interacting with the user equipment for signaling and data; wherein: the configured scheduling delay is not less than the minimum scheduling delay and is not greater than 3ms; The user equipment is scheduled by using the configured scheduling delay. By adopting the above solution, the efficiency of data transmission can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a base station and a transmission scheduling method. Background technique [0002] In a long term evolution (Long Term Evolution, LTE) communication system, a base station schedules transmission of downlink data and transmission of uplink data through downlink control signaling (Downlink Control Information, DCI) in a subframe. For example, for the transmission of downlink data, the base station indicates to the user equipment (User Equipment, UE) the resource configuration information for downlink data transmission (including modulation and coding format, location information of allocated physical resource blocks, etc.) After deciphering its own DCI, it receives data on the Physical Downlink Shared Channel (PDSCH) according to the resource configuration information contained in it. If the UE can decipher the data correctly, the UE will receive data in a certain subframe n+k(k&g...
