Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for processing uplink scheduling.
Background
Machine to Machine (M2M) communication is an important issue of the fifth Generation mobile communication technology (5G, 5th Generation) currently studied, and is also an important application field of the future wireless communication. In the M2M project, some applications require high communication delay, such as vehicle-to-vehicle communication, automatic control, virtual reality, smart grid, etc. These applications want to minimize the end-to-end delay so that the terminal can respond as quickly as possible.
In a Long-Term Evolution (LTE) system in the related art, data delay mainly includes data processing delay, transmission delay, scheduling processing delay, and the like. The scheduling processing delay refers to a time from when the base station transmits the scheduling information to the user equipment to when the user equipment starts actual data transmission or reception according to the scheduling information. In the existing LTE system, downlink data transmission can be performed in the same subframe as that for transmitting scheduling information, so that the delay time of downlink scheduling processing is short. However, uplink data must be transmitted in the 4 th subframe after the subframe in which the scheduling information is transmitted. Since the length of each LTE subframe of the existing system is 1ms, the uplink scheduling processing delay is about 4 ms.
In order to overcome the scheduling processing delay, in the related art, a method of fast uplink data transmission may be adopted, that is, for some application service data, the base station may instruct the user equipment to perform corresponding uplink data transmission in a kth subframe after the subframe in which the scheduling information is received, where k is the scheduling processing delay and k is less than 4. Since the scheduling processing delay of the fast uplink data transmission is very short, the ue needs to have a stronger processing capability so as to decode the scheduling information and prepare the data block to be transmitted within the allowed time.
Since there may be multiple terminal users in the LTE system, including traditional user equipment and terminal users with strong processing capability that can perform fast uplink data transmission. How to select a proper scheduling processing delay for the user equipment needs to be solved urgently.
In view of the above problems in the related art, no effective solution has been found at present.
