System and method for preventing terminal measuring and scheduling conflict

Abstract

The invention provides a system and method for preventing terminal measuring and scheduling conflict. The method comprises the following step: when a terminal in the cell dedicated channel state uses the high speed downlink packet access service and a base station needs to use the high speed shared control channel on the time slot 0 to schedule the terminal, the terminal and the base station determine the system frames to be measured according to the same conditions, wherein the terminal carries out neighbor cell measuring only on the system frames to be measured, and the base station schedules the terminal only on other system frames except the system frames to be measured. The invention ensures that the terminal not only can complete normal measurement but also does not affect reception of the high speed downlink packet access data, namely avoiding conflict between terminal measuring and monitoring of the high speed shared control channel on the time slot 0, and the method has little effect on the whole measuring process and is easy to implement.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a system and method for preventing terminal measurement and scheduling conflicts. Background technique [0002] An important feature of the third-generation mobile communication system is the unbalanced traffic volume of the uplink and downlink, and the traffic volume of the downlink will generally be greater than that of the uplink. In response to this requirement, 3GPP (3rd Generation Partnership Project) introduced the HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) feature into the 3G specification. In the HSDPA feature, by introducing AMC (Adaptive Modulation and Coding, adaptive coding and modulation), HARQ (Hybrid Automatic Retransmission Request, hybrid automatic retransmission request) technology and related technologies to reduce network processing delay, to provide higher The rate of the downlink packet service is higher, which im...

Then the terminal needs to receive TS0 of two frequency points at the same time in one frame. At present, the terminal only supports one frequency point to work. Therefore, in this case, a conflict of receiving frequency points is caused.

According to the original process, if the adjacent cell measurement is performed at regular intervals in the CELL_DCH (Cell Dedicated Channel) state, the HS-SCCH information at this time may not be received, resulting in the inability to receive subsequent HS -PDSCH data; if the terminal still listens to HS-SCCH every frame, then the terminal does not have time to perform neighbor cell measurements
