Problems solved by technology

[0004] In summary, in the prior art, when the base station scheduler schedules the terminal for the first time or does not schedule the user for a long time, the base station scheduler cannot obtain the downlink channel quality measurement information through an effective way, and cannot accurately set the modulation mode , coding rate, and downlink HS-SCCH and HS-PDSCH transmission power, etc., which will lead to a decrease in system throughput and a waste of system resources

Embodiment Construction

[0060] At present, with the introduction of HSUPA technology, it has become a trend for user terminals to provide services through HSUPA and HSDPA technologies at the same time; in order to facilitate uplink interference control, HSUPA technology introduces SNPL (service Cell and adjacent cell path loss ratio relationship) is used to control uplink interference. The SNPL of the terminal is obtained based on the signal strength measurement of the pilot channel of the serving cell and the adjacent cell. For the TDD system, it is based on the signal strength of the serving cell and the adjacent cell. P-CCPCH RSCP (received channel level of the primary common control physical channel) and the P-CCPCH (primary common control physical channel) transmission power of the serving cell and neighboring cells broadcast by the system message are obtained, and the SNPL reflects the downlink channel quality situation. In addition, the measurement quantity of UPH (terminal power headroom) is ...

Abstract

The invention provides a method for realizing the HSDPA (High Speed Downlink Packet Access) dispatching, comprising the following steps of: receiving channel measurement information; and transmitting the received channel measurement information to the entity of a network side which realizes the HSDPA dispatching according to the channel measurement information. The invention further provides a device for realizing the HSDPA dispatching. The method and the device solve the problem that the entity of the network side has no channel measurement information for the dispatching reference, under the condition of the initiate HSDPA dispatching or the long break, and provide the channel measurement information for the HSDPA dispatching under the initiate dispatching or the long break, thereby guaranteeing the capability of system throughput and resource utilization rate and the like and being applicable to the HSPA of TDD mode (Time Division Duplex) and the HSPA enhanced level system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for realizing HSDPA (High Speed ​​Downlink Packet Access) scheduling. Background technique [0002] At present, in the TDD (Time Division Duplex) system using HSDPA technology, when the base station has initial downlink data to send to the terminal, the base station first uses the HS-SCCH (High Speed ​​Shared Control Channel) scheduling control channel to carry UE (user equipment, or The identification information H-RNTI (High Speed ​​Downlink Terminal Identification) of the terminal) addresses the terminal, and then carries user data through the HS-DSCH (High Speed ​​Downlink Shared Channel) channel; while the terminal continuously monitors the HS-SCCH channel, when passing When the HS-SCCH knows that it is scheduled, it receives and decodes data on the corresponding HS-PDSCH (High Speed ​​Physical Downlink Shared Channel). signaling indication ...
