Problems solved by technology

[0005] The interference problem under the same-frequency heterogeneous network, due to the introduction of the interference coordination mechanism, may cause a large difference in the quality of the wireless link on different time domain resources, which has an impact on UE (User Equipment, user equipment) measurement; However, in the prior art, there is no specific solution for how the base station notifies the UE of relevant measurement information through the air interface.

Embodiment 1

[0046] For the scenario of heterogeneous networks with the same frequency, Embodiment 1 of the present invention provides a method for processing measurement restriction information, such as Figure 5 As shown, the method includes the following steps:

[0047]In step 501, the network side determines whether to enable measurement according to the measurement restriction information or to disable measurement according to the measurement restriction information. Wherein, the measurement restriction information includes: measurement restriction information for the serving cell, and / or measurement restriction information for neighboring cells. In addition, the measurement restriction information is ABS subframe information.

[0048] It should be noted that in practical applications, when it is necessary to restrict measurement on ABS subframes, the network side determines to enable measurement according to the measurement restriction information; if it does not need to restrict me...

Embodiment 2

[0064] In the embodiment of the present invention, the configuration process of the measurement restriction information is described. The configuration of the measurement restriction information requires a switch, that is, whether to enable the measurement restriction; if the measurement restriction is enabled, whether to use the pre-stored measurement restriction information can be set Delta signaling mode configuration.

[0065] Among them, for the configuration of the serving cell measurement restriction information, there is no need to indicate the PCI list or interval, such as Figure 6 As shown, it is a schematic diagram of extending the configuration of the measurement restriction information for the serving cell in the measurement configuration message; for the configuration of the measurement restriction information of the neighboring cell, it is necessary to indicate the PCI list or interval, such as Figure 7 As shown, it is a schematic diagram of extending the conf...

Embodiment 3

[0068] In the embodiment of the present invention, the reconfiguration process of measurement restriction information is described. This embodiment takes the coexistence scenario of Macro and Pico enhanced with CRE as an example, as Figure 8 The schematic diagram of the application scenario is shown.

[0069] When the MUE (that is, the UE under the Macro) is very close to Pico-1 and Pico-2, the Macro cell is configured for the UE to measure the restriction information of neighboring cells, that is, the ABS subframe of the Macro cell and the PCI of the two Pico cells (PIC -1 and PCI-2). When the UE later moves to the vicinity of Pico-3 and Pico-4, the Macro cell needs to reconfigure the measurement restriction information, then the ABS subframe for configuring the Macro cell will no longer be displayed in the reconfiguration message, but the new two PCI of a Pico cell, that is, PCI-3 and PCI-4. After receiving the reconfiguration message, the UE uses the original Macro ABS s...

Abstract

The invention discloses a measurement restriction information processing method and equipment. The method comprises the following steps that user equipment (UE) receives information coming from a network, wherein the information carries information of enabling or disabling measurement conducted according to measurement restriction information, carries the measurement restriction information or does not carry the measurement restriction information; if the information carries the information of enabling the measurement conducted according to the measurement restriction information, when the information carries the measurement restriction information, the UE conducts measurement according to the measurement restriction information; and when the information does not carry the measurement restriction information, the UE conducts the measurement according to pre-stored measurement restriction information. In the embodiment of the invention, by transmitting the information which carries the measurement restriction information or does not carry the measurement restriction information to the UE, the UE radio link monitoring and the radio resource management (RRM) measurement reliability are ensured and simultaneously the cost of signaling configuration is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method and equipment for measurement restriction information. Background technique [0002] With the increasing data rate and service load requirements, the traditional method of using macro base station single-layer coverage to provide access can no longer meet the demand. In order to solve this problem, layered coverage can be used to deploy some low-level coverage in hot spots or indoors. Power base stations (such as HNB / HeNB / Pico / Relay, etc.) to meet access requirements. Among them, this low-power base station is a base station device applied in a home indoor environment, an office environment, or other hotspot small-coverage environments, enabling operators to provide attractive services with higher data rates and lower costs. [0003] In the prior art, after the LTE (Long Term Evolution, Long Term Evolution) system introduces low-power base stat...
