Description

Pilot frequency measurement method and device

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a pilot frequency measurement method and apparatus.

Background

When the existing terminal carries out pilot frequency measurement, if the radio frequency capability of the terminal is limited, the connection with the current service frequency point needs to be interrupted within a period of time, including the interruption of the receiving and sending of data service and possible same frequency measurement of a service cell, and the pilot frequency measurement is carried out when the frequency is modulated to a frequency point to be measured. This interruption time is the measurement interval (measurement gap). In the existing LTE scheme, since the synchronization symbol transmission interval is 5ms, the length of the measurement gap is 6ms, where 1ms is used for frequency modulation, and the remaining 5ms is used for cell access and measurement. The starting position of the measurement interval (specifically, which subframe of which radio frame starts) is issued by RRC signaling, and the signaling content includes: gap offset (gap offset) and gap period, the gap offset being the amount of subframe offset within the period. The starting subframe number of the measurement interval and the position of the starting subframe number can be determined by the interval offset (gap offset) and the interval gap period.

In the 5G technology, because the working frequency point is high, the bandwidth is large, and the path loss and noise are serious, if the deployment scheme of the LTE technology is adopted, the cell coverage is seriously reduced, and therefore, the beam forming scheme becomes a relatively common deployment scheme. To achieve reasonable coverage, multiple beams are employed. A cell or node comprises a plurality of beams, each of which may transmit measurement reference symbols. The reference symbols for measurement and the synchronization symbols are transmitted in a polling mode by considering resource overhead and access delay.

The number of beams per cell/node is different for different frequency points. If a unified reference symbol for measurement and a synchronous symbol for sending polling intervals are formulated, the resource overhead occupied by the reference symbol is larger for the condition that the number of beams is more; for the case of a small number of beams, the measurement delay is large. Therefore, different frequency points may transmit polling intervals corresponding to different reference symbols. The transmission polling interval of the reference symbols and the synchronization symbols affects the inter-frequency measurement interval of the terminal. When the terminal performs pilot frequency measurement, the frequency of the radio frequency link needs to be modulated to be the same as the frequency of the target frequency point through the pilot frequency interval so as to perform pilot frequency measurement. The measurement interval is established in relation to the polling time interval of the measurement reference symbols and the system performance. If the time length of the measurement interval is less than the polling time interval of the reference symbol, the terminal is likely to be unable to receive the measurement reference symbol within the measurement interval, and the measurement is completed; if the time length of the measurement interval is too long, the transmission of data is affected, and the system performance is reduced. The existing unified inter-frequency measurement interval scheme is not suitable for the reference symbol polling transmission mechanism of the 5G technology.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

First embodiment

As shown in fig. 1, a first embodiment of the present invention provides an inter-frequency measurement method applied to a terminal, where the method includes:

step 11, obtaining working frequency point information of a pilot frequency adjacent cell of a terminal and a beam polling interval of a pilot frequency adjacent cell sending reference symbols;

step 12, according to the beam polling interval of the reference symbol sent by the pilot frequency adjacent cell, determining the pilot frequency measurement interval of the reference symbol sent by the pilot frequency adjacent cell;

and step 13, receiving a reference symbol sent by the pilot frequency adjacent cell on a working frequency point which is frequency-modulated to the pilot frequency adjacent cell in the pilot frequency measurement interval, and carrying out pilot frequency measurement according to the reference symbol.

The pilot frequency measurement method provided by the embodiment of the invention can dynamically determine the pilot frequency measurement interval; specifically, different beam polling intervals correspond to different inter-frequency measurement intervals.

Specifically, step 11 in the above embodiment of the present invention includes:

and step 111, receiving the working frequency point information of the pilot frequency adjacent cell of the terminal, which is sent by the service cell of the terminal. The service cell of the terminal can carry the working frequency point information of the pilot frequency adjacent cell through the measurement configuration information, namely the measurement configuration information contains the working frequency point information of the pilot frequency adjacent cell.

Further, the step of acquiring the beam polling interval in the above embodiment of the present invention includes:

step 112, determining reference symbol sending information of the pilot frequency adjacent cell according to the working frequency point information of the pilot frequency adjacent cell and a preset mapping relation between the frequency point information and the reference symbol sending information;

and step 113, determining a beam polling interval for transmitting the reference symbol by the pilot frequency neighboring cell according to the reference symbol transmission information.

The method is characterized in that the mapping relation between the frequency point information and the reference symbol sending information is preset, namely the terminal and the network implicitly clarify the reference symbol sending information after the working frequency point of the pilot frequency adjacent cell is clarified, so that the pilot frequency measurement interval is determined.

Alternatively, the step of acquiring the beam polling interval includes:

step 114, receiving reference symbol sending information of a pilot frequency adjacent cell of the terminal, which is sent by a service cell of the terminal;

and step 115, determining a beam polling interval for transmitting the reference symbol by the pilot frequency neighboring cell according to the reference symbol transmission information.

In this way, the reference symbol sending information of the pilot frequency adjacent cell is determined by the network side and then sent to the terminal, so that the terminal determines the pilot frequency measurement interval.

Specifically, the reference symbol transmission information includes: a beam polling interval to transmit reference symbols; or, the reference symbol transmission information includes: the number of beams contained in the pilot frequency neighborhood and the number of beams for simultaneously transmitting the reference symbols. The terminal can determine the beam polling interval according to the number of beams contained in the pilot frequency adjacent region and the number of beams simultaneously transmitting the reference symbols.

For example, if a certain inter-frequency adjacent cell has 20 beams, at time T1, the beam 1/5/9/13/17 transmits the reference symbol at the same time; at time T2, beam 2/6/10/14/18 transmits reference symbols simultaneously; at time T3, beam 3/7/11/15/19 transmits reference symbols simultaneously; at time T4, beam 4/8/12/16/20 transmits reference symbols simultaneously. If beam 1 transmits a reference symbol at time T1, then beam 1 transmits the reference symbol the next time at time T (1+ 4). The reference symbol transmission information is: the beam polling interval for transmitting the reference symbol is 4; or, the reference symbol sending information is: the number of beams of the pilot frequency adjacent region is 20, and the number of beams for simultaneously transmitting the reference symbols is 5; the number of beams 20 of the inter-frequency neighbor is divided by the number of beams 5 for simultaneously transmitting reference symbols to obtain the beam polling interval 4 for transmitting reference symbols. That is, the reference symbol transmission information may directly indicate the beam polling interval or indirectly indicate the beam polling interval, and is not limited herein.

Further, in the foregoing embodiment of the present invention, after the terminal determines the inter-frequency measurement interval in which the inter-frequency neighboring cell sends the reference symbol, the method further includes:

and step 14, reporting the information of the determined pilot frequency measurement interval to a service cell of the terminal. The serving cell does not schedule the terminal within the corresponding time window, so that the terminal can perform inter-frequency measurement on the inter-frequency neighboring cell within the inter-frequency measurement interval.

Specifically, the information of the inter-frequency measurement interval includes: the terminal measures the interval length of pilot frequency measurement in the pilot frequency adjacent region; or,

In the above embodiment of the present invention, the information of the inter-frequency measurement interval needs to include the inter-frequency measurement interval length for the terminal to perform inter-frequency measurement on the inter-frequency neighboring cell; however, when the terminal needs to perform pilot frequency measurement on a plurality of pilot frequency adjacent cells, the serving cell does not determine the sequence and the measurement times of the pilot frequency measurement performed by the terminal; therefore, in order to enable the serving cell to better master the information of the pilot frequency measurement of the terminal, the terminal reports the pilot frequency measurement interval length and also reports the frequency point sequence and the measurement times of the pilot frequency measurement. Subsequently, the serving cell can send the frequency point sequence and the measurement times of the pilot frequency measurement to the pilot frequency neighboring cell, and the pilot frequency measurement can be performed when the terminal performs the pilot frequency measurement in the pilot frequency neighboring cell, so that the pilot frequency measurement efficiency is improved.

In summary, in the first embodiment of the present invention, the measurement information sent by the network side (i.e. the serving cell of the terminal) to the terminal not only carries the working frequency point information of the inter-frequency neighboring cell, but also carries the beam polling interval for the inter-frequency neighboring cell to send the reference symbol, so that the terminal can dynamically determine different inter-frequency measurement intervals according to different beam polling intervals, which not only enables the terminal to receive all reference symbols sent by the inter-frequency neighboring cell in the inter-frequency measurement interval, but also does not affect the transmission of other data due to the excessively long inter-frequency measurement interval, thereby improving the system performance.

Second embodiment

As shown in fig. 2, a second embodiment of the present invention further provides an inter-frequency measurement method, which is applied to a serving cell of a terminal, and the method includes:

step 21, sending the working frequency point information of the pilot frequency adjacent cell of the terminal to the terminal;

step 22, obtaining a pilot frequency measurement interval of the terminal, wherein the pilot frequency measurement is performed on a pilot frequency neighboring cell on a working frequency point of the pilot frequency neighboring cell to which the terminal frequency is modulated in the pilot frequency measurement interval;

and step 23, not scheduling the terminal in the pilot frequency measurement interval.

In the second embodiment of the present invention, the serving cell may carry the working frequency point information of the pilot frequency neighboring cell through the measurement configuration information, that is, the measurement configuration information includes the working frequency point information of the pilot frequency neighboring cell.

Specifically, the beam polling interval for the inter-frequency neighboring cell to send the reference symbol may be determined by the serving cell and sent to the terminal, so that the terminal determines the inter-frequency measurement interval according to the beam polling interval; i.e. after step 21, the method further comprises:

step 24, obtaining a beam polling interval of a pilot frequency adjacent cell sending reference symbol of the terminal;

and step 25, transmitting the beam polling interval of the reference symbol transmitted by the pilot frequency adjacent cell to a terminal, and determining the pilot frequency measurement interval of the reference symbol transmitted by the pilot frequency adjacent cell by the terminal according to the beam polling interval.

Or, the beam polling interval for the pilot frequency neighboring cell to send the reference symbol may also be determined by the terminal, and then the terminal continues to determine the pilot frequency measurement interval according to the beam polling interval. The method is characterized in that the mapping relation between the frequency point information and the reference symbol sending information is preset, namely the terminal and the network implicitly clarify the reference symbol sending information after the working frequency point of the pilot frequency adjacent cell is clarified, so that the pilot frequency measurement interval is determined.

Further, step 22 in the above embodiment of the present invention includes:

step 221, receiving the pilot frequency measurement interval information determined by the terminal reported by the terminal before the pilot frequency measurement. The serving cell does not schedule the terminal within the corresponding time window, so that the terminal can perform inter-frequency measurement on the inter-frequency neighboring cell within the inter-frequency measurement interval.

First, the step 22 of determining the inter-frequency measurement interval comprises:

step 222, determining a pilot frequency measurement interval corresponding to a maximum beam polling interval according to the maximum beam polling interval in the beam polling intervals of one or more pilot frequency neighboring cells for sending reference symbols;

in step 223, the inter-frequency measurement interval corresponding to the largest beam polling interval is determined as the inter-frequency measurement interval of the terminal.

In the method, before the terminal performs pilot frequency measurement, the terminal does not need to report information of a measurement interval, the serving cell selects a beam polling interval of a maximum reference symbol from beam polling intervals of different reference symbols corresponding to different frequency points as a reference according to measurement configuration information, determines the pilot frequency measurement interval according to the maximum beam polling interval, and does not schedule the terminal in the pilot frequency measurement interval.

It should be noted that there are 3 determination methods for the inter-frequency measurement interval of the terminal, which are respectively:

the first, step 24, comprises:

241, determining reference symbol sending information of the pilot frequency adjacent cell according to the working frequency point information of the pilot frequency adjacent cell and a preset mapping relation between the frequency point information and the reference symbol sending information;

step 242, determining the beam polling interval for the inter-frequency neighboring cell to send the reference symbol according to the reference symbol sending information.

The method is characterized in that the mapping relation between the frequency point information and the reference symbol sending information is preset, namely the reference symbol sending information is implicitly determined after the working frequency points of the pilot frequency adjacent regions are determined by the terminal and the network, so that the beam polling interval is determined.

The second, step 24, comprises:

step 243, sending a first request message carrying the identification information of the pilot frequency neighboring cell to the base station controller;

step 244, receiving the reference symbol sending information of the pilot frequency neighboring cell issued by the base station controller according to the identification information of the pilot frequency neighboring cell;

step 245, determining the beam polling interval for the pilot frequency neighboring cell to send the reference symbol according to the reference symbol sending information.

Specifically, the serving cell and the inter-frequency neighboring cell report the selected reference symbol transmission information to the base station controller. The serving cell requests the base station controller for sending information about the reference symbol of the inter-frequency neighboring cell, the base station controller informs the serving cell of the information about the sending information about the reference symbol of the inter-frequency neighboring cell, and the serving cell sends the information about the sending information about the reference symbol of the inter-frequency neighboring cell to the terminal (for example, the information is sent by measurement configuration information, that is, the measurement list includes not only the frequency point information but also the corresponding information about the sending information about the reference symbol).

The third, step 24, comprises:

step 246, sending a second request message carrying the identification information of the serving cell to the inter-frequency neighboring cell;

step 247, receiving reference symbol sending information of the inter-frequency neighboring cell itself, which is sent by the inter-frequency neighboring cell according to the identification information of the serving cell;

step 248, determining the beam polling interval of the pilot frequency neighboring cell for sending the reference symbol according to the reference symbol sending information.

And respective reference symbols are directly interacted between the service cell and the pilot frequency adjacent cell through signaling to send information. The serving cell sends the obtained reference symbol sending information of the inter-frequency neighboring cell to the terminal (for example, the serving cell sends the information through measurement configuration, that is, the measurement list includes the frequency point information and also includes the corresponding reference symbol sending information).

Specifically, the sending information of the reference symbol of the inter-frequency neighboring cell includes: a beam polling interval of a pilot frequency adjacent cell sending reference symbols; or, the sending information of the reference symbol of the inter-frequency neighboring cell includes: the number of beams contained in the pilot frequency neighborhood and the number of beams for simultaneously transmitting the reference symbols. And the terminal or the service cell or the pilot frequency adjacent cell can determine the beam polling interval according to the number of beams contained in the pilot frequency adjacent cell and the number of beams simultaneously sending the reference symbols.

In summary, in the inter-frequency measurement method provided in the second embodiment of the present invention, resource overhead and access delay are considered, and the reference symbols for measurement are transmitted in a polling manner. Because the number of the wave beams corresponding to different frequency points is different, the polling intervals (the sending intervals of the reference symbols) are different; the pilot frequency measurement method provided by the embodiment of the invention can dynamically select the pilot frequency measurement interval length during pilot frequency measurement, and dynamically select the pilot frequency measurement interval length according to the beam polling intervals of different reference symbols adopted by different frequency points, so that a terminal can receive all reference symbols sent by pilot frequency adjacent regions in the pilot frequency measurement interval, the transmission of other data cannot be influenced due to the overlong pilot frequency measurement interval, and the system performance is improved.

In summary, in the inter-frequency measurement apparatus provided in the fourth embodiment of the present invention, the reference symbols for measurement are transmitted in a polling manner in consideration of the resource overhead and the access delay.
