Problems solved by technology

[0017] The disadvantage of the prior art is: if the HSDPA resources are allocated to time slot 0, then the HSDPA channels configured in time slot 0 can be HS-SCCH and HS-PDSCH
For HS-SCCH, since the UE needs to continuously monitor and receive the HS-SCCH and decode it, the HS-SCCH is configured in time slot 0. When receiving the HS-SCCH, the UE cannot change its receiver frequency at the same time. Neighboring cell signals of other frequencies or neighboring cell signals of other systems, thus, inter-frequency and inter-system measurements cannot be performed
For HS-PDSCH, the HS-PDSCH is configured in time slot 0. After receiving the scheduling command on the HS-SCCH, it needs to continuously monitor the HS-PDSCH channel of time slot 0, and the UE cannot perform inter-frequency and inter-system measurements.
To put it simply, the disadvantage of the existing technology is: after the HSDPA resources are allocated to time slot 0, there is a problem that the UE cannot perform inter-frequency and inter-system measurement. At present, no effective solution has been proposed for this problem

Embodiment 1

[0084] Embodiment 1 is: the configuration of the current HSDPA resources is: HS-SCCH, the HSDPA downlink scheduling control channel, and HS-PDSCH are continuously configured on time slot 0. Correspondingly, the configuration information includes the measurement period and the measurement duration; The above-mentioned scheduling measurement mode is a mode of configuring measurement occasions in high-layer signaling.

[0085] Such as image 3 As shown, the method flow of this embodiment includes the following steps:

[0086] Step 101, the network sets the configuration information of a certain UE according to the measurement frequency requirement information such as the number of adjacent cells and frequency points that the UE needs to measure, such as the number of measurement samples required to be reported per unit time. Configuration information includes measurement period and measurement duration.

[0087] Here, the measurement period and the measurement duration are parame...

Embodiment 2

[0095] Embodiment 2 is: the current configuration of HSDPA resources is: HS-SCCH and HS-PDSCH are discontinuously configured on time slot 0, and correspondingly, the configuration information is the configuration ratio of HSDPA resources on time slot 0; the scheduling measurement The mode is a mode of time-division allocation of HSDPA resources by high-layer signaling.

[0096] Here, referring to the realizable scheme of UE measurement in the CELL-FACH state in the existing TDD system, since the PICH and S-CCPCH are time-division multiplexed on the same physical resource, at the time of PICH resource configuration, the UE can perform Inter-frequency and inter-system measurements. Then, after the HSDPA resource is configured on the time slot 0 in the present invention, the measurement problem can also be solved by configuring the HSDPA resource in time division.

[0105] Embodiment 3 is: the current configuration of HSDPA resources is: HS-PDSCH is configured on time slot 0, and correspondingly, the configuration information includes a measurement period and a measurement duration; the scheduling measurement method is a base station scheduler scheduling measurement method.

[0106] Such as Figure 5 As shown, the method flow of this embodiment includes the following steps:

[0107] Step 301. The network sets the configuration information of a certain UE according to the measurement frequency requirement information such as the number of neighboring cells and frequency points that the UE needs to measure, such as the number of measurement samples required to be reported per unit time. The configuration information includes a measurement period and a measurement duration.

[0108] Step 302: Send the configuration information including the measurement period and the measurement duration to the base station scheduler through a high-layer si...

Abstract

The invention discloses a method of realizing scheduling measurement, comprising: according to the arrangement of the current HSDPA resources, transmitting corresponding arrangement information through a high level signalling process, and adopting corresponding scheduling measurement mode to executing the scheduling measurement. The invention also discloses a system of realizing the scheduling measurement. According to the method and the systme of the invention, not only the HSDPA resources are arranged behind time slot 0, causing UE to execute alien frequencies and alien system measurement, but also mobility of UE is better ensured.

Description

technical field [0001] The present invention relates to scheduling measurement technology, in particular to a method and system for realizing scheduling measurement in time slot 0 based on High Speed ​​Downlink Packet Access (HSDPA) resource configuration. Background technique [0002] In order to meet users' growing demand for high-speed packet data access services, 3GPP Rel5 introduces HSDPA technology. Among them, adaptive modulation and coding (AMC) or HARQ technology is used to realize high-order modulation; and a media access control layer HSDPA (MAC-hs) entity is added at the base station side to realize fast data scheduling. Using the key technologies of HSDPA, such as AMC / HARQ and MAC-hs, not only can obtain higher user peak rate and cell data throughput rate, but also reduce data transmission delay. [0003] After the introduction of HSDPA technology, the corresponding channels include: HS-DSCH, High Speed ​​Downlink Shared Channel; HS-PDSCH, High Speed ​​Physical...
