Method and system for reporting scheduling information

Abstract

The invention discloses a method for reporting scheduling information. The method comprises the following steps: a terminal reports the scheduling information to the base station, wherein in the indication mode of combining domain combination values in scheduling information, the scheduling information indicates that in the scheduling information, the current terminal power clear space is the terminal power clear space corresponding to one of the two carriers. The invention also discloses a system for reporting scheduling information. A reporting unit in the system at the terminal side is used for reporting the scheduling information to the base station, wherein in the indication mode of combining domain combination values in scheduling information, the scheduling information indicates that in the scheduling information, the current terminal power clear space is the terminal power clear space corresponding to one of the two carriers. The method and system can be used for reporting scheduling information; and the scheduling information can clearly indicate that the terminal power clear space domain in the scheduling information aims at the terminal power clear space of one of the two carriers, thereby facilitating the pertinent analysis of the base station and scheduling the resources in a better way.

Description

technical field [0001] The present invention relates to a scheduling information reporting technology in a wireless communication system, in particular to a method and system for reporting scheduling information when data transmission is performed on dual carriers using high-speed packet access technology. Background technique [0002] In the existing system, the scheduling information is the reference information for scheduling by the most core Node B. Here, the Node B is the Node B of the base station. The scheduling information method in the existing system is as follows: [0003] The scheduling information is located at the end of the protocol data unit of the MAC entity handling the enhanced dedicated channel. The scheduling information is used to give the Node B a better perspective to observe the total amount of system resources required by the terminal and the total amount of system resources actually used or available by the terminal. Scheduling information is se...

[0012] It can be seen that, using the scheduling information obtained according to the existing rules, although there is information in the terminal power net space domain, Node B still cannot accurately know the specific power headroom conditions corresponding to each carrier, resulting in the fact that Node B cannot know more The terminal power headroom is used inappropriately for higher rate and higher power data transmission, that is, the rate at which the terminal sends data cannot be increased; or, in fact, Node B may use the terminal power headroom incorrectly for higher rate, higher power data transmission, that is, the rate at which the terminal sends data is incorrectly increased

In either case, Node B cannot make full use of system resources and terminal power, so that it cannot provide optimal scheduling that matches the current network performance and terminal interference conditions. In extreme cases, it will lead to unreasonable power increases and interference If the value is too high, the user capacity will be reduced, the effective rate of data sent by the terminal will be reduced, and the catastrophic consequences will be dropped.
