Description

Measurement interval configuration method for inter-frequency measurement unlicensed spectrum and service base station

This application is required to be submitted to the Chinese Patent Office on January 30, 2015, the application number is CN201510054812.9, and the invention title is “a method for measuring the interval of measurement of unlicensed spectrum and service base station”. The entire content of which is incorporated herein by reference.

Technical field

The present invention relates to the field of wireless network technologies, and in particular, to a method for configuring a measurement interval of an inter-frequency measurement unlicensed spectrum and a serving base station.

Background technique

With the rapid development of wireless network technology, the current licensed spectrum can no longer meet the growing demand for communication services. In order to meet the growing demand for communication services and further improve the utilization of spectrum resources, 3GPP (3rd Generation Partnership Project, third generation) The Partner Program) proposes LTE (Long Term Evolution) authorized access technology to help LTE networks use unlicensed spectrum. One of the key points when using an unlicensed spectrum in an LTE network is to ensure that the LTE authorized secondary access technology can coexist with the current access technology of the unlicensed spectrum. Therefore, the LTE network needs an LBT (Listen Before Talk) mechanism, that is, the LTE network detects whether the channel corresponding to the unlicensed spectrum is idle before using the unlicensed spectrum. If not, the LTE network cannot use the LTE network. Unlicensed spectrum, if idle, the LTE network can use the unlicensed spectrum.

Currently, before a terminal in LTE adds an unlicensed spectrum cell as a secondary serving cell, the terminal needs to perform inter-frequency measurement on the unlicensed spectrum to detect the reference signal received power/quality of the unlicensed spectrum corresponding channel (Reference Signal Received Power/ Quality, RSRP/RSRQ), and the basic principle of the inter-frequency measurement is: when the terminal transmits/receives data on the carrier frequency 1, the terminal needs to measure the RSRP/RSRQ on the carrier frequency 2, so that the terminal adds or switches the inter-frequency to the carrier. The serving cell corresponding to frequency 2. Before the inter-frequency measurement is performed by the terminal, the serving base station needs to perform inter-frequency measurement configuration for the terminal. The traditional inter-frequency measurement configuration has two modes: one, the measurement period of the inter-frequency measurement is 40 ms; and the measurement period of the inter-frequency measurement is 80ms, and in both cases, the measurement interval of the inter-frequency measurement is 6ms, that is, every 40ms or 80ms, the terminal needs to disconnect from the serving cell of carrier frequency 1, switch the receiver to carrier frequency 2 and detect the RSRP/RSRQ of the neighboring cell on carrier frequency 2. In the LTE authorized access access technology, one of the implementation signals of the RRM (Radio Resource Management) measurement signal is a periodic short control signal, that is, the serving base station transmits within 2.5 ms every 50 ms. Short control signal for RRM.

It can be seen that, because the sending period of the short control signal sent by the serving base station is 50 ms and the length of the sending time period is 2.5 ms, the traditional inter-frequency measurement configuration mode may cause the terminal to fail to detect the cell in the unlicensed spectrum in the LTE authorized auxiliary access technology. The problem of the transmitted measurement signal for the RRM is that the measurement result of the inter-frequency measurement on the unlicensed spectrum of the terminal is inaccurate.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a method for configuring a measurement interval of an inter-frequency measurement unlicensed spectrum according to an embodiment of the present invention. As shown in FIG. 1, the method may include the following steps:

S101. When the measurement signal sent on the channel corresponding to the unlicensed spectrum is the short control signal transmission mode, the serving base station configures the measurement period for measuring the measurement interval of the unlicensed spectrum by the inter-frequency measurement as M transmission periods.

In this embodiment of the present invention, the sending period is a period in which a neighboring cell on the unlicensed spectrum sends a measurement signal, where M is an integer greater than or equal to 1.

S102. The serving base station configures a measurement interval in each measurement period according to a preset configuration principle.

In the embodiment of the present invention, the measurement interval in each measurement period covers a time period for transmitting the measurement signal in one of the transmission periods in the measurement period.

As an optional implementation manner, the sending period of the measurement signal sent by the neighboring cell may be 50 ms, and the manner in which the neighboring cell sends the measurement signal in one transmission period is as follows: The neighboring cell sends the measurement signal in consecutive subframes, that is, in a transmission period, the time period for transmitting the measurement signal includes a time segment and the time length of the time segment (time segmentation) may be 2.5 ms; 2. The neighboring cell sends the measurement signal in a non-contiguous subframe, that is, the number of time segments included in the time period for transmitting the measurement signal is an integer greater than 1 in a transmission period, if the time period includes The number of time segments is 3, and the sum of the lengths of time segments included in the time segment may be 2.5 ms. The optimal manner for the neighboring cell to send the measurement signal in one transmission period is the first mode, which can reduce the time of the receiver carrier frequency switching of the terminal, and is beneficial to improving the throughput of the terminal.

In the embodiment of the present invention, each measurement interval may include at least one interval segment, and the number of interval segments included in each measurement interval is equal to a time segment included in the time period for transmitting the measurement signal covered by the measurement interval. The number of intervals, one interval segment covers a time segment, and the start time of each interval segment is earlier than the start time of the time segment covered by the interval segment and the end time of each interval segment is later than The time segment end time covered by the interval segment, wherein the length of time that the interval segment is greater than the time segment it covers is the time at which the terminal receiver switches from one carrier frequency to another carrier frequency. which is:

When the neighboring cell sends the measurement signal in consecutive subframes, the serving base station selects one of the transmission periods of each measurement period (the one of the transmission periods is any one of the transmission periods within the measurement period and the one of the transmission periods is within one of the transmission periods) The time period includes a time segment), and configures a measurement interval (the measurement interval covers a time period in the one of the transmission periods) in the one of the transmission periods, and the measurement interval includes an interval segment, the measurement interval The start time is earlier than the start time of the time period covered by the time interval and the end time of the measurement interval is later than the end time of the time period covered by the measurement interval, and the difference between the time length of the measurement interval and the time length of the time interval If the time length of the time period covered by the measurement interval is 2.5 ms, the time length of the measurement interval is greater than 2.5 ms and less than or equal to 3.5 ms, and the start time of the measurement interval is longer than the time period covered by the measurement interval. The length of time when the start time occurs early may be (l _gap -l _scs )/2, where l _gap is the length of time of the measurement interval and l _{scs is} the test The length of the time period covered by the quantity interval is not limited in the embodiment of the present invention;

When the neighboring cell sends the measurement signal in the non-contiguous subframe, the serving base station selects one of the transmission periods of each measurement period (the one of the transmission periods is any one of the transmission periods and one of the transmission periods) The time period inside includes multiple time segments) and one of them Configuring a measurement interval in the transmission period, the measurement interval includes a plurality of interval segments, and the number of interval segments included in the measurement interval is equal to the number of time segments included in the time period covered by the measurement interval, and one interval segment Covering a time segment and the start time of each interval segment is earlier than the start time of the time segment covered by the interval segment, and the end time of each interval segment is later than the time segment of the interval segment The end time, wherein the difference between the length of time of each interval segment and the time length of the time segment covered by the interval segment is less than or equal to 1 ms.

In the embodiment of the present invention, when a neighboring cell sends a measurement signal in a non-contiguous subframe and the interval between adjacent time segments is relatively short, such as when the interval between adjacent time segments is less than or equal to 1 ms, the service The base station may select one of the transmission periods of the measurement period and configure a measurement interval in the one of the transmission periods, the measurement interval includes an interval segment, and the measurement interval (interval segment) starts earlier than the one of the measurement intervals The start time of the first time segment in the transmission period and the end time of the measurement interval (interval segment) is later than the end time of the last time segment in the one of the transmission periods, thus reducing the terminal receiver from one The time when the carrier frequency is switched to another carrier frequency improves the communication time between the terminal and the serving base station, thereby improving the throughput of the terminal.

In the embodiment of the present invention, for example, when a neighboring cell sends a measurement signal in consecutive subframes, it is assumed that M is equal to 1, and the time period for transmitting the measurement signal is 2.5 ms and the measurement of the serving base station configuration is performed. The time interval of the interval is 3 ms, and the measurement interval of the inter-frequency measurement unlicensed spectrum configured by the serving base station may be as shown in FIG. 3, and FIG. 3 is a structure of the measurement interval of the inter-frequency measurement unlicensed spectrum disclosed in the embodiment of the present invention. schematic diagram.

The time length of each time segment is 1 ms, 1 ms, and 0.5 ms, respectively, and the service base station configures a measurement interval including three interval segments in one measurement period, and each interval segment has a time length of 2 ms, respectively. 2ms and 1ms, the measurement interval of the inter-frequency measurement unlicensed spectrum configured by the serving base station may be as shown in FIG. 4, and FIG. 4 is another measurement of the inter-frequency measurement unlicensed spectrum disclosed in the embodiment of the present invention. Schematic diagram of the volume interval. As shown in FIG. 4, A in FIG. 4 indicates that the neighboring cell transmits measurement signals in time segments of 3 ms, 1 ms, and 0.5 ms, respectively, every 50 ms, and B in FIG. 4 indicates every 50 ms. The serving base station configures a measurement interval for the terminal, and the measurement interval includes three interval segments, and different interval segments cover different time segments for transmitting measurement signals, and the measurement interval is first in one measurement period. The start time of the interval segment occurs at the first 0.5 ms of the start time of the time segment covered by it and the end time of the first interval segment occurs at the end 0.5 of the end time of the time segment of its coverage. At ms, the start time of the second interval segment of the measurement interval occurs at the first 0.5 ms of the start time of the time segment covered by it and the end time of the second interval segment occurs at the time of its coverage At the last 0.5 ms of the end time of the segment, the start time of the third interval segment of the measurement interval occurs at the first 0.25 ms of the start time of the time segment covered by it and the third interval segment End time appears in the time segment of its coverage After the end time of 0.25ms.
