No. 15/745,298 filed on Jan. 16, 2018, which is a national phase under 35 U.S.C. § 371 of PCT International Application No. PCT/CN2015/089392 filed on Sep. 10, 2015. The contents of these applications are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The disclosure relates to communications, and particularly to a channel measurement and measurement result reporting method and device.

BACKGROUND

In a conventional wireless cellular communication system, a measurement mechanism plays a very important role in idle-state cell selection and reselection, connected-state handover and network planning and optimization. Measured quantities mainly include Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ). In an idle state, a terminal determines whether to continue camping in a cell or not or whether it is necessary to reselect a neighbor cell of the same frequency or a different frequency or not under a configuration provided by system information based on RSRP and RSRQ measurement results of the camping cell and the neighbor cell. In such a process, the terminal is not required to report the measurement results to the network side. In a connected state, the terminal performs event-triggered or periodical measurement result reporting under a dedicated signaling configuration of the system, and a network side (such as a base station) performs handover or addition or deletion of a secondary carrier/cell during carrier aggregation/dual connectivity according to the reported results.
At present, it is considered to use an unlicensed frequency band (for example, 2.4 GHz or 5.8 GHz) to extend the frequency for wireless cellular system, and two methods are mainly adopted, i.e. License Assisted Access (LAA) and Long Term Evolution (LTE)/Wireless Fidelity (WiFi) Aggregation. The two methods mainly have the following characteristics: (1) an aggregated resource belongs to unlicensed frequency band, and is only used as complementary resources for the licensed frequency band; and (2) use of the unlicensed frequency band is limited not only by scheduling of a base station, but also limited by a load of the frequency band, and namely, the unlicensed frequency band may be used through a competition mechanism. Therefore, compared with the licensed frequency band, the unlicensed frequency band is required to be measured by the terminal as timely as possible, so that the resource of the unlicensed frequency band may be fully utilized, and the terminal may access the unlicensed frequency band as fast as possible.
When a conventional manner is adopted, if a terminal is in a connected state, when the terminal or a network generates a service (for example, a File Transfer Protocol (FTP) service) suitable for transmission on an unlicensed frequency band, the network configures the terminal to perform unlicensed frequency band channel measurement in the conventional manner, the terminal reports according to network configuration, and the network determines whether to configure the corresponding frequency band to the terminal or not according to a reporting result. However, if the terminal is in an idle state, when the terminal or the network generates the service (for example, the FTP service) suitable for transmission on the unlicensed frequency band, the terminal is required to enter the connected state in a licensed frequency band and perform unlicensed frequency band measurement by configuration. After measurement and reporting by the terminal, the network determines whether to configure a certain channel of the unlicensed frequency band to the terminal as an LAA secondary carrier or a LTE/WiFi aggregation carrier or not.
Thus it can be seen that, if the unlicensed frequency band channel is required to be configured as an LAA secondary carrier or a LTE/WiFi aggregation carrier, a terminal is required to access a licensed frequency band at first and perform measurement and reporting after configuration in the licensed frequency band, and then a base station may finally configure the carrier to the terminal. Therefore, a configuration procedure may be too long. Measurement and reporting of the corresponding carrier may be completed only after the configuration from the network. Moreover, a measurement and reporting latency is longer, particularly for an idle-state terminal or for a terminal performing handover, in configuration of the LAA secondary carrier or the LTE/WiFi aggregation carrier.

SUMMARY

The disclosure provides a channel measurement and measurement result reporting method and device, which may reduce the number of interaction signalings between terminal equipment and network equipment, reduce signaling overhead and increase an access rate and access efficiency of an unlicensed frequency band channel carrier when the network equipment is required to configure a channel of an unlicensed frequency band to be a secondary carrier of the terminal equipment.

The unlicensed frequency band refers to a frequency band free and open to the public and shared by different systems, and the unlicensed frequency band may also be called an “unauthorized frequency band” (for example, a 2.4 GHz frequency band and a 5.8 GHz frequency band). However, the scope of protection of the embodiments of the disclosure is not limited to these names.
In the embodiments of the disclosure, both the network equipment and the terminal equipment may support LAA and WiFi secondary carrier addition, modification and deletion functions.
FIG. 1 is a schematic flowchart of a channel measurement and measurement result reporting method according to an embodiment of the disclosure. The method may be executed by terminal equipment, and as shown in FIG. 1, the method 100 includes the following operations.
In S110, terminal equipment measures a channel of an unlicensed frequency band according to configuration information, wherein the terminal equipment is in an idle state.
In S120, the terminal equipment transmits a measurement result of measuring the channel of the unlicensed frequency band to network equipment.
Therefore, in the embodiment of the disclosure, the terminal equipment in the idle state measures the channel of the unlicensed frequency band according to the configuration information, and reports the measurement result to the network equipment. In such a manner, when the network equipment is required to configure the channel of the unlicensed frequency band to be a secondary carrier of the terminal equipment, the number of interaction signalings between the terminal equipment and the network equipment may be reduced, thereby reducing signaling overhead and increasing an access rate and access efficiency of an unlicensed frequency band channel carrier.
It should be understood that, in the embodiment of the disclosure, a connected state refers to a state that the terminal equipment establishes a Radio Resource Control (RRC) connection with the network equipment, and the idle state refers to a state that the terminal equipment establishes no RRC connection with the network equipment.
Optionally, in S110, the configuration information may be transmitted to the terminal equipment by the network equipment, and may also be its own default configuration information of the terminal equipment. The default configuration information may be a latest configuration automatically recorded by the terminal equipment. The terminal equipment may use the same configuration for measurement in different channel measurement processes under the condition that a cell where the terminal equipment is located does not change.
Optionally, as shown in FIG. 2, the method 100 further includes the following operation.
In S130, the terminal equipment receives the configuration information transmitted by the network equipment.
Correspondingly, S110 is specifically implemented as follows. The channel of the unlicensed frequency band is measured according to the received configuration information transmitted by the network equipment.
Optionally, in S130, the terminal equipment may receive a broadcast message transmitted by the network equipment, the broadcast message including the configuration information.
Optionally, the broadcast message may be a broadcast message contained in a Master Information Block (MIB), or is called an MIB message. The broadcast message may also be a broadcast message contained in a System Information Block (SIB), or is called an SIB message. The broadcast message may further be another broadcast message, and there are no limits made in the disclosure.
Preferably, the broadcast message is an SIB message. The network equipment may implement inclusion of the configuration information in the SIB message in a manner of adding an Information Element (IE) into an SIB message in the conventional art. For example, an IE corresponding to the configuration information may be added into existing SIB1 or SIB/3/4/5. A new SIB message different from the SIB message in the conventional art may also be introduced, and the new SIB message includes the IE corresponding to the configuration information.
Optionally, if the terminal equipment is in the connected state, the terminal equipment may receive an RRC connection release message transmitted by the network equipment, the RRC connection release message including the configuration information. Moreover, when the terminal equipment receives the RRC connection release message, the RRC connection is released, a state of the terminal equipment is switched from the connected state to the idle state, and then the terminal equipment in the idle state measures the channel of the unlicensed frequency band according to a configuration of the received configuration information. In such a possible implementation mode, if the configuration information only includes parameter information related to channel measurement, for example, frequency point information and measurement period information, the network equipment is also required to transmit a network capability information indicating whether the network equipment supports an LAA and/or LTE/WiFi aggregation function or not to the terminal equipment.
In the embodiment of the disclosure, optionally, the configuration information is configured to indicate that the network equipment supports an LAA function, and/or, an LTE and WiFi aggregation function. That is, if the configuration information transmitted by the network equipment only indicates a capability of the network equipment, when the network equipment supports the LAA function and/or the LTE/WiFi aggregation function, the terminal equipment may measure the channel of the unlicensed frequency band according to a default configuration stored therein, and the default configuration stored by the terminal equipment may include the frequency information, measurement period information, measurement parameter information and the like configured by the terminal equipment based on implementation. For example, the terminal equipment determines that an unlicensed frequency band to be measured is 5.8 GHz, a measurement period is several seconds and a measurement duration is several milliseconds based on its own implementation. However, during channel measurement, according to the default configuration stored therein, the practically measured unlicensed frequency band is 5.1 GHz, the measurement period is several seconds, and the measurement duration is several milliseconds.
Optionally, in S110, the configuration information includes at least one of the following information: the frequency information of the unlicensed frequency band, the measurement period information, measurement duration information and the measurement parameter(s).
Specifically, the terminal equipment correspondingly measures a measurement parameter in the measurement duration on a frequency indicated in the indication information according to the measurement period in the configuration information, and records a measurement result. The terminal equipment may cover an original measurement result with a new measurement result after completing a measurement.
Optionally, the measurement periods indicated by the measurement period information may be the same, and may also be different. The measurement duration corresponding to each measurement or each measurement period may be the same, and may also be different. That is, each measurement period may include a variable measurement duration. For example, the measurement period may be configured according to a priority of a service or a channel load condition. If the priority of the service is higher or the load is lower, the measurement period may be set to be shorter. If the priority of the service is lower or the load is higher, the measurement period may be set to be longer. The measurement duration may also be configured according to a similar rule. If a previous measurement result condition obtained by the terminal equipment is clear, for example, a Received Signal Strength Indicator (RSSI) is far higher than or lower than a threshold value, the terminal equipment may use a shorter measurement duration. If the previous measurement result condition obtained by the terminal equipment is poor, that is, the channel is more complicated, for example, the RSSI is approximate to the threshold value, the measurement duration may be correspondingly extended.
Optionally, the measurement parameter information includes at least one of the following parameters: RSRP, RSRQ and an RSSI. However, the disclosure is not limited.
Optionally, the terminal equipment may directly report the measurement result to the network equipment after completing measurement, and may also notify the network equipment of information indicating that it stores the measurement result and then report the measurement result when the network equipment requires the terminal equipment to report the measurement result.
In the embodiment of the disclosure, optionally, the terminal equipment may transmit the measurement result to the network equipment through dedicated signaling in a process of establishing the RRC connection with the network equipment. For example, the terminal equipment may transmit an RRC connection establishment request message or an RRC connection establishment completion message to the network equipment, the RRC connection establishment request message or the RRC connection establishment completion message including the measurement result.
In the embodiment of the disclosure, optionally, the terminal equipment may notify the network equipment of the information indicating that it stores the measurement result. For example, as shown in FIG. 3, S120 may specifically include the following operations.
In S121, first indication information indicating that the terminal equipment stores the measurement result is transmitted to the network equipment.
In S122, second indication information transmitted by the network equipment is received, the second indication information being configured to indicate the terminal equipment to report the measurement result.
In S123, the measurement result is transmitted to the network equipment according to the second indication information.
Specifically, the terminal equipment may include the first indication information in the RRC connection establishment request message transmitted to the network equipment. The network equipment may learn about that the terminal equipment has stored the measurement result of the unlicensed frequency band after receiving the RRC connection establishment request message, and includes the indication information indicating the terminal equipment to report the measurement result in an RRC connection establishment message transmitted to the terminal equipment when the network equipment requires the terminal equipment to report the measurement result. The terminal equipment may include the measurement result in the RRC connection establishment completion message transmitted to the network equipment.
If the terminal equipment does not include the first indication information indicating that it stores the measurement result in the RRC connection establishment request message, the terminal equipment may include the first indication information indicating that it stores the measurement result in the RRC connection establishment completion message. The network equipment may include the indication information indicating the terminal equipment to report the measurement result in an RRC reconfiguration message or include the indication information indicating the terminal equipment to report the measurement result in a terminal equipment specific (or terminal dedicated) message after establishment of the RRC connection is completed. Then, the terminal equipment may include the measurement result in an RRC reconfiguration completion message or terminal equipment specific message transmitted to the network equipment.
Optionally, S121 may specifically be implemented as follows. The RRC connection establishment request message is transmitted to the network equipment, the RRC connection establishment request message including the first indication information. Correspondingly, S122 is implemented as follows. An RRC connection establishment message transmitted by the network equipment is received, the RRC connection establishment message including the second indication information. S123 is implemented as follows. The RRC connection establishment completion message is transmitted to the network equipment, the RRC connection establishment completion message including the measurement result.
Optionally, S121 may specifically be implemented as follows. The RRC connection establishment completion message is transmitted to the network equipment, the RRC connection establishment completion message including the first indication information. Correspondingly, S122 is implemented as follows. An RRC reconfiguration message transmitted by the network equipment is received, the RRC reconfiguration message including the second indication information. S123 is implemented as follows. An RRC reconfiguration completion message is transmitted to the network equipment, the RRC reconfiguration completion message including the measurement result.
Optionally, if the second indication information transmitted to the terminal equipment by the network equipment in S122 is included in the terminal equipment specific message, the terminal equipment may correspondingly transmit a terminal equipment dedicated message to the network equipment in S123, the terminal equipment dedicated message including the measurement result. Alternatively, the terminal equipment may communicate with the network equipment through the terminal equipment dedicated message after entering the connected state. The terminal equipment may include the indication information indicating that it stores the measurement result or the measurement result in the terminal equipment dedicated message for transmitting to the network equipment. For example, the terminal equipment dedicated message may be an unlicensed frequency band measurement reporting message, but the scope of protection of the disclosure is not limited to this name In the embodiment of the disclosure, optionally, the terminal equipment may determine whether LAA secondary carrier configuration or WiFi secondary carrier configuration is required or not according to a service requirement, and transmit the measurement result to the network equipment when determining that LAA secondary carrier configuration or WiFi secondary carrier configuration is required.
In other words, the terminal equipment may determine whether it is necessary to report the measurement result to the network equipment or not according to the service requirement. If the terminal equipment does not generate a service suitable for transmission on the unlicensed frequency band, the terminal equipment may select not to report the measurement result. If the terminal equipment generates the service (for example, an FTP service) suitable for transmission on the unlicensed frequency band, the terminal equipment determines that the measurement result is required to be transmitted to the network equipment. At this moment, the terminal equipment may directly report the measurement result to the network equipment, and may also notify the network equipment of the information indicating that it stores the measurement result at first and then transmit the measurement result to the network equipment after receiving a message indicating the terminal equipment to transmit the measurement result from the network equipment.
In such a manner, the network equipment may configure the terminal equipment to use the unlicensed frequency band secondary carrier in an LAA or a WiFi manner according to the service requirement after receiving the measurement result transmitted by the terminal equipment.

It is noted that these examples are not intended to limit the scope of the embodiments of the disclosure but only to help those skilled in the art to better understand the embodiments of the disclosure.

In S306, the UE in the connected state receives an RRC reconfiguration message transmitted by the eNB.
In S307, the UE in the connected state transmits an RRC reconfiguration completion message to the eNB.

It should also be understood that the method 300 may also not include S302. At this moment, network capability information may be included in the dedicated signaling transmitted in S301.

In such a manner, when the network equipment is required to configure the channel of the unlicensed frequency band to be a secondary carrier of the terminal equipment, the number of interaction signalings between the terminal equipment and the network equipment may be reduced, thereby reducing signaling overhead, and increasing an access rate and access efficiency of an unlicensed frequency band channel carrier.

Since the terminal equipment in the idle state may measure the channel of the unlicensed frequency band, when the network equipment is required to configure the channel of the unlicensed frequency band to be a secondary carrier of the terminal equipment, the number of interaction signalings between the terminal equipment and the network equipment may be reduced, thereby reducing signaling overhead, and increasing an access rate and access efficiency of an unlicensed frequency band channel carrier.
