Description
Technical Field
The invention relates to the technical field of communication, in particular to a base station and a method for measuring a pilot frequency cell of the base station.
Background
In a long Term Evolution (L ong Term Evolution, L TE) system, a User Equipment (UE) in a connected state needs to measure a serving cell and an adjacent cell, and further, whether the serving cell and the adjacent cell meet reporting conditions is evaluated according to a measurement result.
Typically, there is only one serving cell for a UE. The UE receives a system message, a paging message, a Radio Resource Control (RRC) message, and the like in a serving cell. When the UE has a high rate of traffic demand and the UE supports carrier aggregation, the base station may configure multiple serving cells for the UE. One of the cells is called a Primary Cell (PCell), and the other cells are called Secondary cells (scells). The UE receives a system message, a paging message, an RRC message, etc. from the primary cell.
When the UE measures the co-frequency cells, the GAP is not needed. Specifically, the UE may receive the reference signal of the intra-frequency cell while receiving the signal of the serving cell, so as to evaluate whether the signal quality of the intra-frequency cell satisfies the reporting condition.
When measuring the inter-frequency cell, the UE needs to use a measurement GAP (GAP). Specifically, the UE tunes the center frequency of the radio frequency in the GAP to the frequency of the inter-frequency cell, and then the UE can measure the corresponding inter-frequency cell. After the measurement is finished, the UE needs to tune the center frequency of the radio frequency to the frequency of the serving cell again, so that the UE can receive signals in the serving cell. The duration of the GAP is uniformly set to 6ms, and a Repetition Period (MGRP) of the GAP may be configured to 40ms or 80 ms. Therefore, the UE can measure the pilot frequency cell for multiple times and correspondingly obtain multiple measurement values so as to accurately evaluate whether the pilot frequency cell meets the reporting condition.
However, since communication with the serving cell cannot be performed within the GAP, the data transmission rate of the UE is greatly affected in the measurement of the inter-frequency cell.

Detailed Description
In the actual measurement process of the inter-frequency cell, the UE generally receives a synchronization Signal of the inter-frequency cell, synchronizes with the inter-frequency cell, receives a specific Reference Signal (CRS) of the inter-frequency cell based on the synchronization, and evaluates the inter-frequency cell according to the CRS.
Fig. 1 is a schematic structural diagram of a radio frame in an L TE system, referring to fig. 1, each radio frame includes 10 subframes, which are subframe 0, subframe 1, … …, and subframe 9 in sequence, a base station generally transmits a synchronization signal in subframe 0 or subframe 5, in order to enable a UE to measure a synchronization signal of a pilot cell, a measurement GAP needs to cover subframe 0 or subframe 5, in addition, considering that there may be no synchronization between pilot cells at the same frequency, the UE needs to measure at least one downlink subframe of a pilot cell in the GAP, and there are various uplink and downlink subframe configuration modes in the radio frame, for example, in a Time Division Duplex (TDD) -L TE system, there may be only one downlink subframe, or 2 downlink subframes, or 3 downlink subframes, or 4 downlink subframes in 5 consecutive subframes, and thus in the prior art, the measurement GAP is uniformly set to 6 ms.
Since communication with the primary cell cannot be performed in the GAP, the data transmission rate of the UE is greatly affected during the measurement of the inter-frequency cell.
In view of the above problems, embodiments of the present invention provide a method for measuring a pilot frequency cell, where information on whether a UE supports shortening of a measurement gap is obtained, and when the UE supports shortening of the measurement gap, information on the shortened measurement gap is configured for the UE according to the obtained information on whether the UE supports shortening of the measurement gap, so that time for communication interruption with a primary cell during a measurement process can be reduced, and an influence on a data transmission rate of the UE can be reduced.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 2, an embodiment of the present invention provides a method for measuring an inter-frequency cell, where the method may include the following steps:
In a specific implementation, the base station may acquire the capability information of whether the UE supports shortening the measurement gap in various ways. For example, the base station may first send a capability reporting request to the UE, and the UE sends corresponding capability information to the base station after receiving the capability reporting request. The capability reporting request may request the UE to report all capability information of the UE, or may only request the UE to report capability information of whether or not the UE supports shortening of the measurement gap. Of course, the capability information of whether the UE supports shortening the measurement gap may also be obtained indirectly through other devices, which is not listed here.
In an embodiment of the present invention, the obtaining of the capability information of whether the UE supports the shortened measurement gap may include obtaining the capability information of whether the UE supports the inter-frequency cell measurement by applying the shortened measurement gap on all frequencies, that is, the UE may apply the shortened measurement gap on all inter-frequencies to measure the neighboring cell, where the inter-frequencies are frequencies specified by the L TE protocol.
In another embodiment of the present invention, the obtaining of the capability information of whether the UE supports shortening of the measurement gap may include: and acquiring the capability information whether the UE supports the measurement of the pilot frequency cell by applying the shortened measurement gap on a partial frequency. That is, the UE supports shortening the measurement gap only on a partial frequency.
Taking the example that the frequency corresponding to the inter-frequency cell of the UE includes F1 and F2, the UE can support shortening the measurement gap on both F1 and F2, that is, the inter-frequency cell where the UE measures F1 and F2 can both apply the information of the shortened measurement gap. The UE may also support a shortened measurement gap only on F1 or F2, i.e., the inter-frequency cell where the UE measures F1 or F2 may apply the information of the shortened measurement gap.
And step 22, judging whether the UE supports the shortened measurement gap according to the acquired capability information whether the UE supports the shortened measurement gap.
In particular implementations, whether the UE supports shortening of measurement gaps may be indicated by the capability information in a variety of ways. For different indication modes, a corresponding method may be adopted to determine whether the UE supports shortening the measurement gap.
For example, whether the UE supports shortening of a measurement gap may be indicated by a value of a preset bit in the capability information. At this time, after obtaining the capability information, the base station may obtain whether the UE supports shortening the measurement gap by reading the value of the preset bit.
For another example, whether the UE supports shortening of the measurement gap may be indicated by information of a preset field in the capability information. At this time, after acquiring the capability information, the base station may acquire whether the UE supports shortening the measurement gap by reading the information in the preset field.
In specific implementation, the standard measurement gap information is sent to the UE, and the UE measures the inter-frequency cell according to the standard measurement gap information. The standard measurement gap information duration, that is, the measurement gap duration uniformly set in the prior art, is currently 6ms, and the MGRP is 40ms or 80 ms.
And when the UE does not support shortening the measurement gap, the UE measures the pilot frequency cell by adopting standard measurement gap information, namely measuring the pilot frequency cell by adopting the measurement gap with the duration of 6 ms.
In the actual communication process, in order to implement interference cancellation between cells and the like on some frequencies, synchronization needs to be maintained between all the neighboring cells of the frequency, that is, subframe numbers of all the neighboring cells of the frequency are aligned. For example, at a certain time, the subframe numbers corresponding to all the neighboring cells of the frequency are subframe 3. The system frame numbers of the radio frames corresponding to all the neighboring cells of the frequency may be the same or different. Therefore, when all the neighboring cells of a certain frequency are synchronized (referred to as synchronized neighboring cells for short), the base station may configure the corresponding information of the shortened measurement gap for the UE according to whether the UE supports the information of the capability of shortening the measurement gap, so that the duration of the communication interruption with the primary cell may be reduced, and the influence on the data transmission rate of the UE may also be reduced.
In a specific implementation, a pilot frequency cell of a primary cell may have synchronous neighboring cells of multiple frequencies, that is, all neighboring cells of any one of the multiple frequencies are synchronous, at this time, a base station may configure corresponding shortened measurement gap information for the synchronous neighboring cells of all frequencies, or configure corresponding shortened measurement gap information for the synchronous neighboring cells of some of the frequencies, which is not limited specifically. And after receiving the configured measurement gap information, the UE measures the synchronous adjacent cell of the corresponding frequency by adopting the shortened measurement gap information.
Specifically, when there is a synchronization neighboring cell in the inter-frequency cells on all frequencies, the base station may configure information of a corresponding shortened measurement gap for some or all synchronization neighboring cells measured by the UE. When a synchronization neighboring cell exists in the pilot frequency cell on the partial frequency, the base station may configure information of a corresponding shortened measurement gap for the UE to measure part or all of the synchronization neighboring cells.
It should be noted that, in the embodiment of the present invention, the synchronous neighboring cell is a cell that is adjacent to the primary cell of the UE and that can be detected by the UE.
It should be noted that, in the embodiment of the present invention, the length of the shortened measurement gap is shorter than the length of the measurement gap uniformly set in the prior art. For example, if the duration of the measurement gap is uniformly set to be 6ms in the prior art, the shortened inter-measurement duration may be 1ms, 2ms, or 3 ms.
In specific configuration, the length of the shortened measurement gap may also correspond to the frequency of the inter-frequency cell, and the lengths of the shortened measurement gaps corresponding to inter-frequency cells with different frequencies may be different. For example, the base station also configures the duration of the measurement gap used when the UE measures the inter-frequency cell of a certain frequency to be 2ms, and the duration of the measurement gap used when the UE measures the inter-frequency cell of other frequencies to be 3 ms.
In an embodiment of the present invention, to facilitate scheduling, the durations of the measurement gaps corresponding to the inter-frequency cells of each frequency are the same. The length of the shortened measurement gap may be preset. In particular, the information of the shortened measurement gap can be set in various ways.
In an embodiment of the present invention, the information of the shortened measurement gap may include: the period information of the shortened measurement gap and the identification information of the subframe of the main cell corresponding to the shortened measurement gap, wherein the shortened measurement gap at least covers the subframe 0 or the subframe 5 of the corresponding synchronous adjacent cell. At this time, after receiving the shortened measurement gap information, the UE may receive a synchronization signal of the corresponding neighboring cell in subframe 0 or subframe 5 (the subframe of the corresponding primary cell may be subframe 0 or 5, or another subframe), so that the UE and the corresponding neighboring cell acquire synchronization. On the basis of synchronization, the UE can acquire the subframe number corresponding to the subframe of the current neighboring cell, so as to detect the corresponding CRS in the subframe.
In a specific implementation, the period of the shortened measurement gap, that is, the repetition period of the shortened measurement gap, may be 40ms, or may also be 80ms, or of course, may also be other values, and the specific implementation is not limited. For example, in order to effectively measure the synchronous neighbor cells in the shortened measurement gap, the repetition period of the shortened measurement gap may be set to exceed 80ms, for example, 128 ms.
In a specific implementation, the identification information of the primary cell subframe corresponding to the shortened measurement gap may be identification information of a starting subframe of the shortened measurement gap, may also be identification information of a last subframe of the shortened measurement gap, and may of course also be identification information of other subframes of the shortened measurement gap, as long as a subframe covered by the shortened measurement gap can be determined according to the identification information of the primary cell subframe corresponding to the shortened measurement gap.
For example, referring to fig. 3, taking the duration of the shortened measurement gap as 3ms as an example, s1 is a subframe of the primary cell, and s2 is a subframe of the corresponding synchronization (inter-frequency) neighbor cell. At this time, the primary cell start subframe corresponding to the shortened measurement gap may be subframe 6, subframe 7, subframe 8, subframe 1, subframe 2, or subframe 3, and the subframes covered by the corresponding shortened measurement gap are (6, 7, 8), (7, 8, 9), (8, 9, 0), (1, 2, 3), (2, 3, 4), (3, 4, 5), respectively.
In a specific implementation, when the UE supports shortened measurement gaps only on a partial frequency, the configured measurement gaps include standard measurement gaps in addition to the shortened measurement gaps. In an embodiment of the present invention, the identification information of the primary cell subframe corresponding to the shortened measurement gap may be correspondence information between the primary cell subframe corresponding to the shortened measurement gap and a standard measurement gap, that is, the primary cell subframe corresponding to the shortened measurement gap is identified by a correspondence relationship with the standard measurement gap. The expression form of the corresponding relationship information is various, and is not specifically limited.
For example, referring to fig. 3, when the subframe of the standard measurement gap covered primary cell s1 is (7, 8, 9, 0, 1, 2), the identification information of the subframe of the shortened measurement gap corresponding primary cell s1 may be "011100", which indicates that 2 nd, 3 rd, and 4 th subframes of the subframe of the standard measurement gap covered primary cell s1 are the subframes of the shortened measurement gap corresponding primary cell.
In another embodiment of the present invention, in addition to the period information of the shortened measurement gap and the identification information of the primary cell subframe corresponding to the shortened measurement gap, the information of the shortened measurement gap may further include: and the identification information of the subframe of the synchronous adjacent cell corresponding to the shortened measurement gap. At this time, after receiving the identification information of the subframe of the synchronous neighboring cell corresponding to the shortened measurement gap, the UE can measure the CRS in the subframe by using the subframe number of the subframe without acquiring the synchronization signal of the synchronous neighboring cell.
For example, referring to fig. 4, taking the duration of the shortened measurement gap T as 2ms as an example, s3 is the subframe of the primary cell, and s4 is the subframe of the corresponding synchronization neighbor cell. The primary cell subframe corresponding to the shortened measurement gap T is the primary cell subframe corresponding to the shortened measurement gap T, that is, subframe 2, and at this time, the primary cell subframes covered by the shortened measurement gap T are subframes 2 and 3. subframe 2 in s3 corresponds to subframe 5 in s4, and subframe 3 in s3 corresponds to subframe 6 in s 4.
Therefore, in a specific implementation, in addition to the period information of the shortened measurement gap T and the identification information of the primary cell subframe corresponding to the shortened measurement gap, the base station may indicate that the subframe at s4 corresponding to the 1ms in the shortened measurement gap T is the subframe 5, and may also indicate that the subframe at s4 corresponding to the 2ms in the shortened measurement gap T is the subframe 6. At this time, after obtaining the configured measurement information, the UE may directly identify the subframe number of the current subframe, and further measure the corresponding CRS.
In yet another embodiment of the present invention, in addition to the period information of the shortened measurement gap and the identification information of the corresponding primary cell subframe, the information of the shortened measurement gap may further include: and indicating information whether the corresponding synchronous adjacent cell is in frame synchronization with the service cell. Here, the serving cell may be a primary cell or a secondary cell. When the serving cell is a primary cell, the indication information may not need to include identification information of the primary cell. When the serving cell is a non-primary cell, the indication information may include identification information of the serving cell at the same time.
When the synchronous neighboring cell corresponding to the shortened measurement gap is frame-synchronized with the primary cell, the UE may obtain the subframe number of the synchronous neighboring cell according to the frame synchronization information, and may further measure the corresponding CRS.
When the synchronized neighboring cell corresponding to the shortened measurement gap is not synchronized with the primary cell frame, the information of the shortened measurement gap may further include: and the offset of the synchronous adjacent cell corresponding to the shortened measurement gap relative to the subframe of the main cell. The UE may obtain, according to the offset, a subframe number of a current frame of the synchronous neighboring cell corresponding to the shortened measurement gap, and may further measure a corresponding CRS.
For example, referring to fig. 4, the information of the shortened measurement gap may further include: the subframe number offset between s4 and s3 is 3. After receiving the shortened measurement gap information, the UE may determine, according to that the offset of the subframe number between s4 and s3 is 3, the subframe number of the current frame of the synchronous neighboring cell corresponding to the shortened measurement gap, and may further measure the CRS corresponding to the subframe number, and evaluate whether the channel quality of the CRS meets the reporting condition.
It should be noted that, in a specific implementation, if the base station configures the UE to measure the synchronous neighboring cells of multiple frequencies by using the shortened measurement gap, it needs to configure a corresponding shortened measurement gap for the synchronous neighboring cell of each frequency, for example, to indicate whether the synchronous neighboring cell of each frequency is frame-synchronized with the serving cell, or the shortened measurement gap corresponds to a subframe number of the synchronous neighboring cell of each frequency, or an offset between the synchronous neighboring cell of each frequency and a subframe number of the primary cell.
As can be seen from the above, in the method for measuring a pilot frequency cell in the embodiment of the present invention, by obtaining information on whether the UE supports shortening of the measurement gap, when the UE supports shortening of the measurement gap, the UE may configure corresponding measurement gap information for the UE, and measure the pilot frequency cell according to the configured measurement gap information. Since the configured measurement gap information includes the information of the shortened measurement gap, the influence on the data transmission rate of the UE during the measurement process can be reduced.
