Problems solved by technology
Since the CQI reported by the UE to the NodeB in traditional HSDPA is the feedback of factors such as the wireless channel condition, modulation mode, and data block size of the previous scheduled transmission, the NodeB cannot know the relatively accurate downlink channel quality of the current UE based on the CQI. Therefore, it is impossible to set the modulation mode, coding rate and downlink HSDPA channel transmission power of HS-PDSCH relatively accurately. Such inaccurate settings will directly lead to waste of system resources and affect the communication between the base station and user equipment.

Embodiment Construction
[0040] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0041] In the present invention, the UE carries channel measurement information in the synchronization confirmation message fed back to the NodeB, and the NodeB analyzes the received channel measurement information, and performs HSDPA scheduling on the UE according to the channel measurement information.
[0042]In the HSDPA of TDD system, NodeB needs to send downlink data to UE. If UE loses uplink synchronization with NodeB, NodeB can first send an uplink synchronization command to UE through HS-SCCH, so that UE can regain the uplink synchronization state with NodeB; then , the UE feeds back a synchronization acknowledgment message carrying channel measurement information to the NodeB, and the NodeB sends downlink data to the UE after receiving the synchronization acknowledgment. Here, the channel measurement inform...

The invention discloses a method for processing channel measurement information. A base station Node B schedules user equipment (UE), and when the UE loses uplink synchronization with the Node B, the Node B sends an uplink synchronization command to the UE. The invention is characterized in that the method also comprises the step that the Node B receives a synchronization confirmation message which is sent by the UE and carries channel measurement information, and performs high-speed downlink packet access (HSDPA) scheduling on the UE according to the received channel measurement information.The invention also discloses a system for processing channel measurement information, a base station and user equipment, can provide reference information for the HSDPA scheduling performed on the UEby the Node B, and can raise the resource utilization ratio of the system.
Description
technical field [0001] The invention relates to the transmission technology of channel measurement information, in particular to a processing method, system and equipment of channel measurement information in the high-speed downlink packet access (HSDPA) technology. Background technique [0002] In the third generation mobile communication system, three wireless transmission technical specifications based on code division multiple access (CDMA) technology are the mainstream technologies of the third generation mobile communication, including frequency division duplex (FDD) mode, time division duplex (TDD) ) mode, CDMA TDD. In the mobile communication system of TDD mode, the uplink and downlink communication between the base station and the user equipment use different time slots of the same frequency channel, and time is used to separate the receiving and transmitting channels. [0003] In the HSDPA of the TDD system, when the base station NodeB has downlink data to send to...
