Description

Measurement method, base station and user equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a measurement method, a base station, and a user equipment.

Background

At present, a small base station, such as a Pico (micro base station), a HeNB (home base station), a Femto (micro base station), a Relay base station, and other wireless access points, can be placed in a coverage area of a Macro eNB (Macro base station) of an LTE (Long Term Evolution), so that a UE (User Equipment) is under dual coverage of the Macro eNB and the small base station, the maximum capacity of the system can be obtained and is the sum of the capacities of the Macro eNB and the small base station, and the whole communication system has a higher capacity than a conventional LTE Macro base station network. Under the scenes of office buildings, shopping malls, campus networks and the like, the heterogeneous deployment of the small base stations and the macro base stations can effectively enhance network coverage and improve spectrum efficiency, and the small base stations can be accessed to a network in a wired or wireless mode.

In such a heterogeneous network, a UE can only connect to one cell, which is called a serving cell of the UE, and a base station may generally have one or more cells. If the small-sized base station and the macro base station adopt the co-frequency deployment, all the base stations transmit downlink signals including downlink control domain signals and downlink data domain signals on the same carrier, and the UE can receive cell signal interference of another base station when communicating with a serving cell thereof, particularly downlink interference. In general, the interfered cell is called a victim cell, and the cell interfering with this UE is called an aggressor cell.

Due to the interference problem possibly brought by the co-frequency heterogeneous network, a TDM (Time-division multiplexing) technology is usually used, a base station to which an aggressor cell belongs only transmits signals on certain specific subframes, and selects some subframes as ABS (Almost Blank subframes), and transmits signals very rarely on REs (Resource elements) in the ABS subframes, and accordingly, the UE to which the victim cell belongs is subjected to low interference from the aggressor cell in the ABS Subframe Time. In the time domain, the subframe of the victim cell corresponding to the ABS of the aggressor cell is called a low interference subframe, and the victim cell may send downlink information to the interfered UE only on the low interference subframe, thereby ensuring the service requirement or performance requirement of the UE.

In the existing network, besides the co-frequency deployment, the inter-frequency deployment also exists. In inter-frequency deployments, the carrier frequencies of different cells are different. For example, Femto and Pico are deployed within the macro base station, where Femto operates at carrier frequency f1 and Pico and macro base station operate at carrier frequency f 2. When UE1 is in the network of carrier frequency f1, this UE1 is called a connected UE (connected UE) using carrier frequency f1 to communicate with its serving cell Femto. In order to effectively guarantee the mobility of the UE1, the UE1 needs to measure the radio link quality of its neighbor cell Pico of the serving cell Femto, and since the carrier frequency of the neighbor cell Pico is f2, the serving cell Femto informs the UE1 to adjust to the carrier frequency f2, and the UE1 measures the link quality between it and the neighbor cell at the carrier frequency f2, which is called inter-frequency measurement.

In the existing inter-frequency Measurement technology, in order to ensure the quality of a wireless link between the UE and the current serving cell, the UE can only perform Measurement of a fixed Length (Measurement Gap Length) at a specified time domain position in a discontinuous manner, and within a specified inter-frequency Measurement time T, after a time Length MGRP (Measurement Gap Repetition Period) elapses, Measurement of the same frequency is performed repeatedly once, and a time-frequency resource corresponding to each Measurement is called Gap. Generally, within the inter-frequency measurement time T, for the same carrier frequency, multiple gaps are used for inter-frequency measurement, and the UE obtains synchronization information of the measured cell by using the first few gaps. The UE analyzes a Cell-specific Reference Signal (CRS) corresponding to each subframe according to the acquired synchronization information, so as to obtain quality information of a wireless link with the measured Cell according to the CRS Signal.

In the course of implementing the present invention, the inventors found that the above prior art has at least the following disadvantages:

the existing pilot frequency measurement technology mainly considers a non-heterogeneous deployment scene, a subframe for pilot frequency measurement in the scene does not have a serious interference problem, and synchronization and precision requirements in the measurement process can be guaranteed. After introduction of co-frequency heterogeneous deployment, a connected UE at a certain carrier frequency may measure a pilot frequency, and the pilot frequency is just used in the above co-frequency heterogeneous deployment, and then subframes corresponding to the pilot frequency measurement Gap may be all high-interference subframes or a mixture of the high-interference subframes and low-interference subframes corresponding to the ABS, and the existing measurement technology cannot configure appropriate pilot frequency measurement parameters to ensure measurement requirements under such circumstances.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The embodiment of the invention relates to a heterogeneous network, wherein the heterogeneous non-network is characterized in that a small base station, such as a Pico wireless access point, a HeNB wireless access point, a Femto wireless access point, a Relay wireless access point and the like, is placed in the coverage range of a macro base station, so that UE is under the dual coverage of a macro eNB and the small base station. When the small-sized base station and the macro base station adopt the co-frequency deployment, the UE can receive the cell signal interference of another base station when communicating with the serving cell of the UE, particularly the downlink interference. In general, the interfered cell is called a victim cell, and the cell interfering with this UE is called an aggressor cell. For example, referring to fig. 1, a HeNB and a Pico are placed in a macro base station, a serving cell of a UE1 and a UE2 is the macro base station, a serving cell of a UE3 is the Pico, a current UE1 is located at the edge of the HeNB, but has no capability of accessing the HeNB, and a UE3 is located within the Pico. At this time, the signal of the macro base station received by the UE3 is an interference signal, the cell affected by the UE3 is the macro base station, the affected cell is Pico, the signal of the HeNB received by the UE1 is an interference signal, the cell affected by the UE1 is the HeNB, and the affected cell is the macro base station. The carrier frequency of the HeNB is f1, the carrier frequency of the Pico is f2, the Pico and the macro base station are in same-frequency heterogeneous deployment, the UE1 utilizes the carrier frequency f1 to communicate with the HeNB of the serving cell, during different-frequency measurement, the UE1 is firstly adjusted to the carrier frequency f2, then the link quality between the UE and the Pico is measured, and during same-frequency measurement, the UE1 can measure the link quality between the UE and the macro base station without adjusting the carrier frequency.

The embodiment of the invention also relates to a TDM technology to reduce the interference in the heterogeneous network. In the time division multiplexing technology, a base station only sends signals on specific time frequency resources of certain subframes, and rarely sends signals on the time frequency resources in the ABS, so that the service requirement or the performance requirement of the UE is ensured. In the LTE system, in the time domain, a base station numbers a transmission signal in units of radio frames, one radio Frame is 10ms long, a corresponding Frame number is referred to as sfn (system Frame number), one radio Frame includes ten subframes, which are numbered 0# to 9# subframes, and one subframe is divided into a plurality of time frequency blocks according to the time domain and the frequency domain. When the TDM technology is adopted, a base station of an infringing cell selects some subframes as ABS subframes in a period, and the base station of the infringing cell rarely sends signals on time-frequency resources in the subframes in ABS subframe time; accordingly, the UE to which the victim cell belongs is subjected to low interference from the aggressor cell within the ABS subframe time. For example. The 8 scattered subframes are selected as ABS subframes in 40 consecutive subframe (40ms) time, and the corresponding pattern may have various forms, such as: 1000000010000000100000001000000010000000, where 1 indicates that the subframe is set as an ABS subframe, and 0 indicates that the subframe is set as another subframe, the rule is to select the first subframe as an ABS subframe in every 8 subframes, and of course, other patterns may also be adopted, which is not specifically limited in the embodiment of the present invention. In the time domain, a subframe of the victim cell corresponding to the ABS of the aggressor cell is called a low interference subframe, and the victim cell may send downlink information to the interfered UE only on the low interference subframe. In the embodiment of the present invention, any related low interference subframe corresponding to an ABS subframe refers to a downlink subframe of a base station, and is not declared one by one for convenience of description.

Referring to fig. 2, the upper part is a schematic diagram of a subframe of an aggression Cell, the lower part is a schematic diagram of a subframe of a victim Cell, a time domain is represented horizontally, 4 consecutive subframes are listed from left to right in the time domain, it is assumed that subframe 1, subframe 2, subframe 3 and subframe 4 are used to represent resource block RB vertically, some resources in the diagram are used to transmit CRS (Cell reference Signal), some resources are used to transmit DL control Signal, some resources are used to transmit data, and some resources are blank cells; and setting the subframe 2 and the subframe 3 as ABS subframes, wherein the two subframes of the victim cell corresponding to the two subframes are low-interference subframes.

The embodiment of the invention relates to an inter-frequency measurement technology, and various inter-frequency measurement parameters are generally configured in a serving cell in inter-frequency measurement. Referring to fig. 3, the time for inter-frequency measurement is Tmeasurement, which is divided into two parts, time T1 for acquiring synchronization information and time T2 for performing inter-frequency measurement. One or more MGRPs are included in T1 and T2, each MGRP has a Gap, all gaps in T1 are used for obtaining synchronization information, and all gaps in T2 are used for inter-frequency measurement. There are multiple gaps within T1 shown in the figure, including: gap1, Gap2, …; there are also multiple gaps within T2, including: GapN, GapN +1, ….

The serving cell referred to in any embodiment of the present invention refers to a base station to which the serving cell belongs, such as eNB, and is simply referred to as serving cell for convenience of description; the victim cell refers to a base station to which the victim cell belongs, such as an eNB, and is referred to as the victim cell for convenience of description; the aggressor cell refers to a base station, such as an eNB, to which the aggressor cell belongs, and is simply referred to as an aggressor cell for convenience of description, and thus is not particularly stated in each step.

Example 1

In order to solve the problem that the existing pilot frequency measurement technology cannot configure pilot frequency measurement parameters according to ABS information, thereby ensuring measurement requirements, this embodiment provides a measurement method, see fig. 4, which includes:

401: a serving cell of User Equipment (UE) acquires related information of an Almost Blank Subframe (ABS) affecting the cell;

402: the serving cell configures pilot frequency measurement configuration information according to the related information of the ABS and sends the pilot frequency measurement configuration information to the UE, so that the UE performs pilot frequency measurement on the victim cell according to the pilot frequency measurement configuration information;

the carrier frequency of the serving cell is different from that of the victim cell, and the carrier frequency of the victim cell is the same as that of the aggressor cell.

In this embodiment, the relevant information affecting the ABS of the cell includes, but is not limited to: ABS information of an aggressor cell or low interference subframe information of a victim cell. The ABS information of the invading cell comprises: the ABS full set or the subset affecting the cell may be preferably represented by an ABS pattern, or may be represented by other manners, which is not specifically limited in the embodiment of the present invention. The low interference subframe information of the victim cell is a subframe within the victim cell corresponding to the full set or subset of ABSs of the aggressor cell.

In the method provided by this embodiment, the serving cell configures the pilot frequency measurement parameter according to the ABS related information of the aggression cell, and sends the pilot frequency measurement parameter to the UE for performing pilot frequency measurement on the victim cell, thereby solving the problem that the existing pilot frequency measurement technology cannot configure the pilot frequency measurement parameter according to the ABS information, and thus ensuring the requirement for pilot frequency measurement.

Example 2

In order to solve the problem that the existing pilot frequency measurement technology cannot configure pilot frequency measurement parameters according to ABS information, thereby ensuring measurement requirements, this embodiment provides a measurement method, see fig. 5, which includes:

501: the serving cell of the user equipment UE acquires relevant information of an Almost Blank Subframe (ABS) affecting the cell.

Specifically, any of the following may be employed:

a serving cell of the UE receives ABS information of an infringing cell sent by the infringing cell;

a serving cell of the UE receives low-interference subframe information of an affected cell sent by the affected cell;

a serving cell of the UE receives ABS information of an aggressor cell sent by an OAM (Operation Administration and Maintenance) system, or low-interference subframe information of a victim cell.

The ABS information affecting the cell is specifically the full set or subset of ABS affecting the cell, and the low-interference subframe of the victim cell is specifically a subframe in the victim cell corresponding to the full set or subset of ABS affecting the cell.

In this embodiment, the serving cell of the UE acquires the relevant information affecting the ABS of the cell through any of the following messages:

an X2 establishment request message X2setup request, an X2 establishment response message X2setup response, a base station configuration update message eNB configuration update, a base station configuration update confirm message enbconconfiguration update acknowledgement, a load information message loadinformation for an inter-frequency cell, or a message newly added to transmit ABS related information infringing a cell;

any of the above messages contains information about the ABS of the aggressing cell.

502: and the serving cell configures pilot frequency measurement configuration information according to the related information of the ABS and sends the pilot frequency measurement configuration information to the UE.

503: and after receiving the pilot frequency measurement configuration information, the UE performs pilot frequency measurement on the victim cell according to the pilot frequency measurement configuration information.

In this embodiment, the carrier frequency of the serving cell is different from the carrier frequency of the victim cell, and the carrier frequency of the victim cell is the same as the carrier frequency of the aggressor cell.

In this embodiment, since the ABS pattern is sparse, the synchronization subframe in the corresponding low-interference subframe is also sparse within the ABS pattern time of 40ms, and in order to improve the measurement accuracy requirement for the pilot frequency scene using the ABS technology, the existing Gap configuration mechanism is changed in step 502, and the pilot frequency measurement configuration information is configured according to the ABS related information, which may include:

and the service cell configures the corresponding measurement starting position, the measurement Gap repetition period MGRP, the measurement Gap in the Gap repetition period and the Gap Length of the Gap within the reporting time Tmeasure of the physical layer measurement result according to the related information of the ABS.

The starting position of the measurement may be pre-specified by the serving cell, and the time length of the MGRP may be configured as follows:

and measuring the duration of the Gap repetition period, wherein the duration corresponds to the related information of the almost blank subframe ABS affecting the cell, which is acquired by the serving cell. Preferably, the duration of the measurement Gap repetition period corresponds to the duration of a low interference subframe pattern used by the victim cell for inter-frequency measurement, or is an integer multiple of the pattern duration.

Further, in one measurement period Tmeasurement, the MGRP may be configured according to the sparsity of the low-interference subframes, and the MGRP may adopt different time lengths, where one time length is configured for synchronization and the other time length is configured for measurement.

After configuring the time length of the MGRP and the initial position of the measurement, the serving cell may send the MGRP to the UE. If two MGRP durations are configured, the serving cell sends both durations to the UE.

The configuration for measuring Gap and Gap length in the Gap repetition period may be: one or more Gaps for inter-frequency measurement can be in one MGRP, and each Gap corresponds to one Gap length; specifically, any of the following methods may be employed:

A. the serving cell sends Gap and Gap length specified according to a preset rule to the UE;

B. the serving cell and the UE agree to acquire Gap and Gap length according to the same preset rule;

C. the serving cell sends Gap specified by a preset rule to the UE, and the UE obtains the GapLength according to the preset rule.

D. The service cell sends a bitmap corresponding to the MGRP to the UE, so that the UE executes pilot frequency measurement at a specified position according to the bitmap; wherein, the low interference subframe set mapped by the bitmap is the full set or the subset of the low interference subframe set in the MGRP.

The preset rules for obtaining Gap and Gap length related to the A, B and the C modes may each include:

the first rule is: the serving cell sends ABS related information to the UE, and in each MGRP, the subframe covered by the Gap is a low interference subframe +1 subframes corresponding to the ABS related information, and the 1 subframe is used for turning on and off a pilot frequency and may be set on the right or left of the low interference subframe, which is not specifically limited in the embodiment of the present invention; the Gap length of the Gap is the duration corresponding to the sub-frame covered by the Gap. Determining all subframes, which are consistent with Gap coverage, as low-interference subframes +1 subframes corresponding to the ABS related information, as gaps; b. a preset range [ lower limit, upper limit ], to which the Gap length calculated as described above is compared: if the Gap length is less than the lower limit, the Gap is not determined; if the lower limit is less than or equal to the Gap length and less than or equal to the upper limit, determining the lower limit as Gap; if the Gap length is larger than the upper limit, the Gap length is taken as the upper limit value and determined as Gap. Therefore, when the low interference corresponding to the continuous ABS related information exceeds a certain length, the subframes covered by the Gap are subsets of a specified length in the continuous low interference subframe set corresponding to the ABS information, all subframes of the subsets are continuous in time, and the duration of the subsets is the duration of the Gap;

the second rule is: the serving cell firstly carries out the following processing on the ABS related information based on pilot frequency measurement, an adjacent non-ABS subframe on the left side or the right side of the ABS subframe is set as the ABS subframe to obtain new ABS related information, the obtained new ABS related information is sent to UE, after the UE receives the ABS related information, Gap and gaplenth are determined according to the principle that a Gap covered subframe is a low-interference subframe corresponding to the ABS related information, wherein the Gap duration is the duration corresponding to the Gap covered subframe.

The ABS information sent by the serving cell to the UE may correspond to each Gap repetition period according to the measurement requirement. In one measurement time Tmeasure, the subframe set corresponding to the ABS information used in the synchronization time includes a low-interference synchronization subframe in the victim cell, and the subsequent subframe set corresponding to the ABS information used in the inter-frequency measurement includes a low-interference synchronization subframe and/or a low-interference subframe in the victim cell. The low-interference synchronization subframe is a subframe used by the victim cell to send synchronization information, and a subframe of an aggressor cell corresponding to the synchronization subframe of the victim cell is set as an ABS subframe.

In this embodiment, the serving cell may further send an indication to the UE, and the UE performs the inter-frequency measurement according to the indication after receiving the indication.

Further, the method may further include:

the serving cell sends the relevant information affecting the ABS of the cell to the UE, and after the UE receives the relevant information, the UE monitors the PDCCH and/or measures the victim cell in a low-interference subframe of the victim cell.

Alternatively, the method may further include:

the serving cell sends the relevant information affecting the ABS of the cell to the UE, and sends an indication to the UE, and the UE monitors the PDCCH and/or measures the victim cell in a low-interference subframe of the victim cell according to the indication after receiving the indication, and the victim cell is in an inactive state.

Specifically, the serving cell may add the relevant information affecting the ABS of the cell to the inter-frequency measurement configuration message, or may send the information to the UE by using RRC dedicated signaling or mac ce.

In the method provided by this embodiment, the serving cell configures the pilot frequency measurement parameter according to the ABS related information of the aggressor cell, and sends the pilot frequency measurement parameter to the UE to perform pilot frequency measurement on the victim cell, so that a corresponding subframe in the pilot frequency measurement Gap is a low-interference subframe, which solves the problem that the existing pilot frequency measurement technology cannot configure the pilot frequency measurement parameter according to the ABS information, thereby ensuring the requirement of pilot frequency measurement.

Example 3

In order to ensure validity of a synchronization signal, that is, to ensure that a synchronization signal is measurable by a UE within a Gap length time, on the basis of embodiment 1 or 2, a step of setting, by an aggressor cell, an ABS subframe according to a synchronization type of a victim cell may be further added to ensure that the synchronization signal of the victim cell is a low-interference subframe, referring to fig. 7, this embodiment provides a measurement method, including:

701: and the invading cell configures the ABS subframe according to the synchronization type of the victim cell.

Specifically, it is configured as follows:

if the victim cell is an FDD (Frequency Division duplex) system, the aggressor cell configures the subframe of the aggressor cell corresponding to the subframe of number 0 and/or number 5 in a radio frame of the victim cell as an ABS subframe;

or if the victim cell is a TDD (Time Division duplex) system, the aggressor cell configures, as an ABS subframe, a subframe of the aggressor cell corresponding to subframes No. 0 and No. 1 in one radio frame of the victim cell, or configures a subframe of the aggressor cell corresponding to subframes No. 5 and No. 6 as an ABS subframe;

or if the victim cell is a TDD system, the aggressor cell configures the subframes of the aggressor cell corresponding to subframes 0, 1, 5, and 6 in one radio frame of the victim cell as ABS subframes;

or if the victim cell is a TDD system, the aggressor cell configures, as ABS subframes, subframes of the aggressor cell corresponding to subframes 0 and 6 in one radio frame of the victim cell, or configures subframes of the aggressor cell corresponding to subframes 1 and 5 as ABS subframes.

One radio frame of the victim cell is a radio frame of the victim cell within time T1 for synchronization within measurement time Tmeasurement. Of course, a plurality of radio frames of the victim cell may also be selected within the time T1 for synchronization, and the above configuration manner is applicable to each selected radio frame, which is not specifically limited in the embodiment of the present invention.

In the embodiment of the invention, within the measurement time Tmeassurement, for the same carrier frequency, a plurality of Gaps are used for measurement, and the UE obtains the synchronization information of the corresponding carrier frequency cell by using the first Gaps. In a 10ms radio frame, both 0# and 5# subframes have PSS (primary synchronization information) and SSS (secondary synchronization information) for FDD systems, primary synchronization information on 1# and 6# subframes, and secondary synchronization information on 0# and 5# subframes for TDD systems. And the UE can solve the CRS signal corresponding to each subframe only after acquiring the primary and secondary synchronization information, and acquire the quality information of the wireless link according to the CRS signal.

For example, the victim cell is an FDD system, and the subframe of the aggressor cell corresponding to the PSS/SSS subframe of the victim cell is set as an ABS subframe. Referring to fig. 8, the 0# and 5# subframes of the 10ms radio frame of the victim cell both include the primary synchronization signal PSS and the secondary synchronization signal SSS, and the aggressor cell at least ensures that one or more subframes corresponding to the 0# and/or 5# subframes are set as ABS subframes within a certain time T (e.g., within 40ms, 20ms,10ms, or a multiple of 40 ms). For another example, the victim cell is a TDD system, where 1# and 6# subframes in the TDD system are locations of a primary synchronization signal PSS, and 0# and 5# subframes are locations of a secondary synchronization signal SSS.
