That is, when the terminal device has a plurality of receiving antennas, the measurement reference signals can be simultaneously received on the plurality of receiving antennas.

In order to increase the gain received by the antenna when the terminal device in the fifth generation mobile communication technology (5-Generation, 5G) New Radio (NR) receives signals, the terminal device needs to use multiple receive beam (beam) pairs.

From a measurement point of view, the terminal device needs to receive the measurement reference signal sent by the network device by using different receiving beams at different times, thereby determining which receiving beam the terminal device uses to obtain a better first measurement result, and the subsequent terminal.

Detailed ways

It should be understood that embodiments of the invention may be applied to any communication system.

That is, the technical solution of the embodiment of the present invention can be applied to various communication systems, for example, a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a broadband. Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD) , Universal Mobile Telecommunication System (UMTS), etc. For convenience of understanding of the solution, the embodiment of the present invention is described by taking a fifth generation mobile communication technology (5-Generation, 5G) communication system as an example.

The present invention describes various embodiments in connection with network devices and terminal devices.

The network device may refer to any entity on the network side that is used to send or receive signals. For example, it may be a device communication of a machine type communication (MTC), a base station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB in LTE). ), base station equipment in a 5G network, and the like.

Furthermore, the terminal device can be any terminal device. Specifically, the terminal device can communicate with one or more core networks (Core Network) via a Radio Access Network (RAN), and can also be referred to as an access terminal, a user equipment (User Equipment, UE), and a user. Unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and a wireless communication function. Handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, and terminal devices in 5G networks, and the like.

In order to increase the gain received by the antenna when the terminal device in the fifth generation mobile communication technology (5-Generation, 5G) New Radio (NR) receives signals, the terminal device needs to use multiple receive beam (beam) pairs. Receive.

FIG. 1 is an example of an application scenario of an implementation of the present invention.

As shown in Figure 1, the network device has 4 transmit beams and the terminal device has 4 receive beams. In the prior art, when the terminal device performs the inter-frequency measurement based on the measurement gap (GAP), only one receiving beam can be used for one measurement in one GAP. That is, the terminal device needs 4 measurement GAPs to complete the measurement corresponding to all the received beams.

That is to say, in the prior art, the terminal device does not consider the signal reception quality of each receiving beam, but measures the same measurement parameters for all the beams on the terminal device, thereby measuring the time of the terminal device. The overhead is multiplied, and the negative effect is to increase the measured power consumption of the terminal device and increase the delay of the terminal device measurement.

Therefore, in the embodiment of the present invention, a method for measurement is provided, where packets are grouped by multiple receiving beams of a terminal device, and radio resource management is performed on the multiple receiving beams based on measurement parameters of each receiving beam group ( Radio Resource Management (RRM) measurement can effectively reduce the time overhead of terminal equipment when measuring on the receiving beam.

As shown in Figure 2, the method includes:

210. The multiple receive beams are divided into multiple receive beam groups, and different measurement parameters are used between the multiple receive beam groups, and the receive beams in each receive beam group adopt the same measurement parameter, and the measurement parameters are used. The terminal device performs RRM measurement.

220. Perform RRM measurement on each of the plurality of receive beam groups based on measurement parameters of each of the plurality of receive beam groups.

In short, the terminal device first needs to divide the multiple receive beams into multiple receive beam groups, and then based on the measurement parameters of each of the multiple receive beam groups in the multiple receive beam groups. RRM measurements are taken on each receive beam.

It should be understood that the measurement parameters of each of the plurality of receive beam groups include, but are not limited to, a measurement period corresponding to each receive beam in the receive beam group.

The following describes an implementation manner in which the terminal device divides the multiple receiving beams into multiple receiving beam groups in the embodiment of the present invention.

Optionally, the terminal device obtains the multiple receive beams into multiple receive beam groups. Taking a first parameter for dividing the plurality of receiving beams; and acquiring a first measurement result of the multiple receiving beams, where the first measurement result of the multiple receiving beams includes a first of each of the plurality of receiving beams a measurement result; then dividing the plurality of receive beams into the plurality of receive beam groups according to the first parameter and the first measurement result of the multiple receive beams.

As an embodiment, the first parameter is a first threshold.

Specifically, the terminal device may compare the first threshold value with the first measurement result of the multiple receiving beams; according to the comparison result of the first threshold value and the first measurement result of the multiple receiving beams, The plurality of receive beams are divided into the plurality of receive beam groups.

For example, the terminal device may divide the multiple received beams into a first receive beam group and a second receive beam group according to a comparison result of the first threshold value and the first measurement result of the multiple receive beams, where The first receiving beam group includes: a receiving beam whose first measurement result is greater than or equal to the first threshold value, and the second receiving beam group includes: the first measurement result of the multiple receiving beams is smaller than The receive beam of the first threshold.

In other words, the terminal device can divide all receive beams into two receive beam groups according to the first threshold. The receiving beam corresponding to the measurement result that is greater than or equal to the first threshold is divided into the first receiving beam group, and the receiving beam corresponding to the measurement result smaller than the first threshold is divided into the second receiving beam group.

Optionally, the first threshold is any one of the following thresholds:

Reference Signal Receiving Power (RSRP) threshold, Reference Signal Receiving Quality (RSRQ) threshold, and Signal to Interference Noise Ratio (RS-SINR) threshold.

It should be understood that the above threshold is only an example of the first threshold. Embodiments of the invention are not limited thereto.

For example, the first threshold value can include a plurality of threshold values.

For another example, the first threshold value may be a threshold value of other indicators.

In another embodiment, the first parameter is a first value that is less than or equal to the number of the plurality of receive beams.

Specifically, the terminal device may select a first receive beam group among the multiple receive beams in an order of high to low according to the first measurement result, where the number of receive beams in the first receive beam group is the first a value; then, a receive beam other than the first receive beam group in the receive beam sequence is determined as a second receive beam group.

For example, the terminal device may follow the first measurement result of the multiple receiving beams according to the first The plurality of receive beams are sorted by high to low or low to high order to form a receive beam sequence; and then the first measurement result is selected from the highest to the lowest order, and the received beam sequence is selected. The first receive beam group.

In other words, the terminal device can arrange the measurement results of all the beams in descending order, wherein the receiving beam corresponding to the best first value measurement result is divided into the first receiving beam group, and the other measurement results are corresponding. The receive beam is divided into a second receive beam group.

In the embodiment of the present invention, the terminal device may perform RRM measurement on each of the multiple receiving beam groups based on the measurement parameters of the multiple receiving beam groups. Description will be made below with reference to FIGS. 3 and 4.

For example, in a case where the receiving beam of the terminal device is divided into two beam groups, the receiving beam in the first beam group can perform one measurement per T1 measurement GAP, and the receiving beam in the second beam group is T2 each. Measuring GAP can perform one measurement.

Assume that the terminal device has 4 receive beams.

As shown in FIG. 3, the terminal device can divide the

beams

2, 3 into beam groups 1, and divide the

beams

1, 4 into beam groups 2. Among them, beam 2 and beam 3 can have one measurement opportunity every 3 GAP cycles, while beam 1 and beam 4 have only one measurement opportunity every 6 GPA cycles.

For another example, as shown in FIG. 4, the terminal device may divide the beam 2 into the beam group 1, and divide the

beams

1, 3, and 4 into the beam group 2. Among them, beam 2 can have one measurement opportunity every 2 GAP cycles, and beam 1, beam 3 and beam 4 have one measurement opportunity every 6 GPA cycles.

It can be seen that the beam 2 shown in FIG. 4 can obtain one measurement opportunity every 2 GAP cycles, and the beam 1, the beam 3 and the beam 4 can obtain a measurement opportunity every 6 GAP cycles, in contrast, The measurement opportunity of the beam 2 with good channel quality is effectively guaranteed, and the measurement opportunities are also provided for the beam 1, the beam 3 and the beam 4.

It should be noted that the terminal device can update the grouping of the beam groups according to the changes of the measurement results of different receiving beams at different times.

For example, the example beam grouping in Figure 4 is {2}, {1, 3, 4}; after a period of time, with the delay of time, it is assumed that the received signal quality of beam 4 may be better, and the beam grouping can be updated to {2 , 4}, {1, 3}.

That is to say, the RRM measurement method in the embodiment of the present invention effectively ensures that the different receive beams are grouped and different measurement parameters are used for different beam groups. Receiving measurement opportunities for beams with better channel quality, and providing a certain measurement opportunity for beams with poor signal reception quality.

Thus, the method of using equal measurement opportunities with respect to each of the receive beams reduces the overhead of the total measurement time and ensures the quality of the measurement of the received good-quality measured beams.

It should be understood that the measurement parameters of the receiving beam group shown in FIG. 3 and FIG. 4 are only exemplary descriptions, which are not specifically limited in the embodiment of the present invention.

The following describes an implementation manner in which the terminal device acquires a first parameter for dividing the multiple received beams.

As an example and not by way of limitation, the terminal device may negotiate with the network device to determine the first parameter; or the terminal device may receive a notification message sent by the network device, the notification message including the first parameter.

Further, if the first parameter is the first value in the foregoing, before the terminal device receives the notification message, the terminal device needs to send the capability information of the terminal device to the network device, where the capability information includes the number of the multiple receiving beams. The network device determines the first value based on the capability information.

It should be understood that the first numerical value is only an exemplary description of the embodiments of the present invention, and the embodiments of the present invention are not limited thereto. For example, the first value can include a plurality of values.

Further, in order to further divide the plurality of receiving beams, the terminal device may further acquire the second measurement result of the multiple receiving beam groups; and re-group the plurality of receiving beam groups according to the second measurement result.

In other words, the terminal device can perform measurement according to the measurement parameters of the multiple receiving beam groups for a period of time, obtain preliminary measurement results, and then re-group the multiple receiving beam groups. Further, the measurement parameters between the individual beam groups can also be reset.

Furthermore, the measurement parameters between the plurality of receive beam groups of the terminal device are different. Therefore, the terminal device needs to determine the multiple receiving beam groups before performing RRM measurement on each of the plurality of receiving beam groups based on measurement parameters of each of the plurality of receiving beam groups. Measurement parameters for each receive beam set.

For example, the terminal device may determine, according to the configuration information sent by the network device, measurement parameters of each of the multiple receive beam groups. In other words, the terminal device allocates different RRM measurement parameters corresponding to different receiving beam groups based on the configuration information of the network, for example, a measurement period corresponding to the receiving beam of the different receiving beam groups of the network configuration.

For another example, the terminal device may negotiate with the network device to determine measurement parameters of each of the plurality of receive beam groups. That is, the terminal device allocates different RRM measurement parameters corresponding to different receiving beam groups based on the pre-agreed by the terminal device and the network.

For example, the terminal device may preset a plurality of measurement parameters, and after the terminal device divides the multiple receive beams into multiple receive beam groups, configure the multiple measurement parameters to the multiple receive beam groups, and notify the network device. .
