Description

Method for starting inter-frequency measurement, user equipment and macro base station

technical field

The present invention relates to the field of communication technology, in particular to a method for starting inter-frequency measurement, user equipment and a macro base station.

Background technique

The 3rd Generation Partnership Project (3GPP) plans to introduce Heterogeneous Network (HetNet) technology in the 12th version of the Universal Mobile Telecommunications System (UMTS). HetNet is a multi-layer Wireless access network technology for networking. The traditional wireless access network is mainly a macro network layer. The macro base station in the macro network needs to cover an entire area to provide continuous and uninterrupted services for all users located in the area. On the other hand, HetNet adds one or more micro-network layers on the basis of the macro-network layer. The transmission power of the micro-base station in the micro-network is smaller than that of the macro-base station, and the coverage is much smaller than that of the macro-base station. The micro network does not need to provide continuous network coverage, but the micro base station can be deployed in the hotspot area within the coverage of the macro base station to provide additional access and transmission channels for user equipment in the hotspot area to load the macro base station Offloading improves the quality of service and improves the throughput of the entire network. In order to ensure that the interference between the macro base station and the micro base station is small, the macro base station and the micro base station work at different frequency points in the case of abundant spectrum resources.

When the macro base station and the micro base station are deployed at different frequency points, in most cases, the user equipment will first search for a cell at the frequency point of the macro base station and camp on or access the macro base station after starting up. In order for the user equipment to access the micro base station to offload the load, it is first necessary to enable the user equipment to search and discover another frequency point micro base station. This process is completed by inter-frequency measurement. The main process is: the macro base station configures different frequency measurement parameters for the user equipment. After the user equipment meets a certain trigger condition, it will measure the signal quality of the base station on other frequencies, and report the measurement report to the wireless network control through the macro base station. device. If the measurement report shows that there are one or more micro base stations with better signal quality on a certain frequency, the radio network controller can issue control signaling to request the user equipment to switch to the micro base station to offload the load on the macro base station.

However, the existing standard stipulates that if the signal quality of the user equipment connected to the macro base station is better than a threshold, the user equipment will not perform inter-frequency measurement. If a micro base station is deployed close to the central area of the macro base station, the signal quality of the macro base station received by the user equipment is good, and inter-frequency measurement will not be started, so it may not be able to access the micro base station. In this case, the micro base station It does not play a load shunting role, which may lead to excessive load of the base station in the macro network.

In order to solve the problem that the load of the macro base station is too large, the following technical solutions exist in the prior art:

If there are micro base stations with different operating frequencies in the cell of the macro base station, an independent channel can be configured for each user equipment in advance, and the user equipment can send a preset signal with constant power on the channel. The micro base station detects the preset signal of the user equipment currently being served by the macro base station on the frequency of the macro base station, compares the received signal power with the transmission power, and judges the distance from the user equipment to the micro base station. For user equipment near the micro base station, the micro base station sends a proximity indication to the macro base station, and the macro base station configures inter-frequency measurement parameters for these user equipments, triggers them to perform inter-frequency measurement, and increases the possibility of these user equipments discovering the micro base station.

In this technical solution, an additional channel needs to be configured for the user equipment, and at the same time, the user equipment continuously or periodically sends preset signals to ensure the detection of the user equipment by the micro base station, which consumes the power of the user equipment and increases the The uplink interference of the macro base station reduces the uplink capacity of the macro base station.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The embodiment of the present invention is applicable to a communication system with a macro base station and a micro base station, and the system may include multiple macro base stations and multiple micro base stations, wherein each macro base station generally has the same transmit power, has the same coverage. A macro base station needs to cover an entire network by itself and provide continuous and uninterrupted services for users accessing the network. One or more micro network layers can be added to the network layer served by the macro base station. These micro network layers can be served by the micro base station. The transmission power of the micro base station is relatively small, and the coverage area is much smaller than that of the macro base station. The micro network does not need to provide continuous network coverage, but is mainly used to cover the hotspot areas in the coverage area of the macro base station, and to offload the load of the macro base station to improve the quality of service and the throughput of the entire network.

Based on the above system, an embodiment of the present invention provides a method for starting inter-frequency measurement, which can be applied to the user equipment side with reference to the method shown in Figure 1, including:

101. A user equipment UE acquires uplink channel reception quality of a micro base station in an access network.

In the embodiment of the present invention, the reception quality of the uplink channel of the micro base station in the access network is generally issued by the macro base station to the UE, that is, the specific implementation of step 101 is that the UE obtains the The reception quality of the uplink channel of the micro base station.

In this implementation, the uplink channel quality is the uplink channel to be measured of the UE on the working frequency of the macro base station by the micro base station in the access network according to the channel measurement information sent by the macro base station. The measurement result obtained by performing the measurement. That is to say, the uplink channel quality information is the channel quality between the user equipment and the micro base station.

Wherein, the channel measurement information indicates the uplink channel to be measured of the UE and identification information of the UE. The specific indication method can respectively indicate the uplink channel to be tested and the UE by carrying the code channel information and scrambling information of the UE, and of course other identification information can also be used in the embodiment of the present invention. The uplink channel described above may use an uplink DPCCH (Dedicated Physical Control Channel, dedicated physical control channel) or the like. For technical solutions related to this part in other embodiments of the present invention, reference may be made to the description herein.

102. The UE calculates a path loss between the UE and the micro base station according to the uplink channel reception quality and the uplink channel transmit power of the UE.

The method for calculating the path loss in step 102 can be implemented in the following manner, specifically:

The received quality of the uplink channel is converted into the received power of the uplink channel of the micro base station, and then the difference between the received power of the uplink channel and the transmit power of the UE on the uplink channel is calculated to determine the path loss.

Wherein, the realization method of converting the reception quality of the uplink channel into the reception power of the uplink channel of the micro base station may refer to the general implementation manner in the industry.

103. If the path loss is less than a preset threshold, the UE sends an inter-frequency measurement request to the macro base station in the access network, so as to request the macro base station to configure inter-frequency measurement parameters for the UE and trigger the The UE performs inter-frequency measurement on the micro base station based on the inter-frequency measurement parameter, wherein the macro base station is a current serving base station of the UE.

Wherein, the preset threshold is positively correlated with the coverage area of the micro base station, and generally can be set according to the limit path loss of the coverage area of the micro base station, that is to say, the larger the coverage area of the micro base station, the larger the preset threshold ; The smaller the coverage area of the micro base station, the smaller the preset threshold.

It is worth noting that, if the path loss is not less than the preset threshold, no inter-frequency measurement parameters are configured, and the user equipment is not triggered to perform inter-frequency measurement.

The macro base stations described in the embodiments of the present invention are all current serving base stations of the UE.

The embodiment of the present invention provides a method for starting inter-frequency measurement, by allowing the user equipment to calculate the path loss information between the user equipment and the micro base station in the access network, and make a judgment based on the path loss information and the preset threshold, and then Whether to perform inter-frequency measurement is determined according to the judgment result. Compared with the need to separately and additionally set new channels and signals for the user equipment in the prior art, only the setting of the user equipment itself is required, and no additional configuration is required, which reduces the power consumption of the user equipment.

Another embodiment provided by the present invention provides another method for starting inter-frequency measurement, which can be applied to the macro base station side with reference to the method flow shown in Figure 2, and the macro base station is a UE in the following method flow The currently accessed macro base station. include:

201. The macro base station receives UE identification information and location information fed back by the micro base station.

Wherein, the position information is the position of the UE within the coverage area of the micro base station determined by the micro base station according to the preset receiving power threshold and the reception quality of the uplink channel of the micro base station.

The reception quality of the uplink channel of the micro base station is the measurement result obtained by the micro base station measuring the uplink channel of the UE to be measured on the working frequency of the macro base station according to the channel measurement information sent by the macro base station .

Wherein, the channel measurement information indicates the uplink channel to be measured of the UE and identification information of the UE.

The above related descriptions of the uplink channel reception quality and channel measurement information of the micro base station are the same as the related descriptions in step 101, which will not be repeated in this embodiment of the present invention.

The part that needs to be explained in the embodiment of the present invention is the determination method of the aforementioned location information. In this method, the preset receiving power threshold is set according to different coverage areas of the micro base station. For places far away from the micro base station, the receiving power threshold The threshold can be set smaller, and the receiving power threshold can be set larger for places closer to the micro base station.

Based on this setting, when determining the location information of the UE, the received power of the uplink channel can be determined according to the received quality of the uplink channel, and then the determined received power is compared with the preset received power threshold to determine the location of the UE. For example, referring to the schematic diagram of area information shown in FIG. 3 , the figure shows three different areas A, B, and C, and three different uplink channel receiving power thresholds x, y, and z are set. When the received power of the uplink channel of the user equipment is greater than x, the user equipment is located in area A; when the received power of the uplink channel of the user equipment is less than x and greater than y, the user equipment is located in area B; when the uplink channel of the user equipment When the received power is less than y and greater than z, the user equipment is located in area C.

202. In response to the UE identification information, the macro base station configures inter-frequency measurement parameters for the UE according to the uplink channel reception quality of the macro base station, the location information, and the preset path loss threshold range and triggers the UE. The UE performs inter-frequency measurement on the micro base station based on the inter-frequency measurement parameter.

Wherein, the reception quality of the uplink channel of the macro base station is a measurement result obtained by the macro base station measuring the uplink channel to be tested of the UE on the working frequency of the macro base station.

For the specific implementation of step 202, the embodiment of the present invention provides one here, as shown in FIG. 4 , specifically:

A2021. The macro base station obtains the preset path loss threshold range corresponding to the location information in the micro cell, and determines the path loss threshold range according to the uplink channel reception quality of the macro base station and the uplink channel transmit power of the UE Describe the path loss from the UE to the macro base station.

A2022. The macro base station configures inter-frequency measurement parameters for the UE when the path loss from the UE to the macro base station falls within a preset path loss threshold range.

It should be noted in this embodiment that, for different locations of the UE, corresponding path loss threshold ranges are also different. The corresponding corresponding relationship can refer to the following description, specifically:

When the UE is in area A1, and PL2<=path loss value<PL1, or,

When UE is in area A2, and PL3<=path loss value<PL2, or,

When UE is in area A3, and PL4<=path loss value<PL3, and so on,

When the UE is in the area An, and PLn+1<=path loss value<PLn.

Wherein, the path loss value is the path loss from the UE to the macro base station, N is an integer, and PLn is a preset path loss threshold. PLn+1 and PLn form a preset path loss threshold range.
