Description

Method for measurement, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a terminal device, and a network device for measurement.

Background

When a terminal device in Long Term Evolution (LTE) performs measurement, a measurement reference signal is generally received in an omni-directional receiving manner. That is, when the terminal device has a plurality of receiving antennas, the measurement reference signal can be simultaneously received on the plurality of receiving antennas.

When a terminal device in a New Radio (NR) of a fifth Generation mobile communication technology (5-Generation, 5G) receives a signal, the terminal device needs to receive the signal by using a plurality of reception beams (beams) in order to increase a gain of antenna reception. From the measurement perspective, the terminal device needs to receive the measurement reference signal sent by the network device at different times by using different receiving beams, so as to determine which receiving beam the terminal device uses to obtain a better first measurement result, and the receiving beam is preferentially used when the subsequent terminal device receives the signal.

Specifically, the terminal device performs inter-frequency measurement based on a measurement GAP (GAP). That is, when a terminal device performs measurement in one GAP, generally, only one measurement can be completed by using one receiving beam. That is, the terminal device needs how many measurement GAPs to complete the measurement corresponding to all the reception beams once for how many reception beams.

Thus, the time overhead of the measurement of the terminal device is multiplied, and the negative effects are to increase the power consumption of the measurement of the terminal device and to increase the time delay of the measurement of the terminal device. Therefore, in the case of using the multi-reception beam by the terminal device, how to reduce the time overhead of the terminal device measurement is a problem to be solved.

Detailed Description

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

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

Various embodiments are described herein in connection with a network device and a terminal device.

A network device may refer to any entity on the network side that transmits or receives signals. For example, the Base Station may be a user equipment for Machine Type Communication (MTC), a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, a Base Station device in a 5G network, or the like.

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

When a terminal device in a New Radio (NR) of a fifth Generation mobile communication technology (5-Generation, 5G) receives a signal, the terminal device needs to receive the signal by using a plurality of reception beams (beams) in order to increase a gain of antenna reception.

FIG. 1 is an example of an application scenario in which the present invention may be implemented.

As shown in fig. 1, the network device has 4 transmit beams and the terminal device has 4 receive beams. In the prior art, when a terminal device performs inter-frequency measurement based on a measurement GAP (GAP), one measurement can be completed only by using one reception beam in one GAP. That is, the terminal device needs 4 measurement GAPs to complete one 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 reception beam, but measures all beams on the terminal device by using the same measurement parameter, so that the time overhead of the measurement of the terminal device is increased by a multiple, and the negative effects are to increase the power consumption of the measurement of the terminal device and increase the time delay of the measurement of the terminal device.

Therefore, an embodiment of the present invention provides a method for measurement, where multiple receiving beams of a terminal device are grouped, and Radio Resource Management (RRM) measurement is performed on the multiple receiving beams based on measurement parameters of each receiving beam group, so as to effectively reduce time overhead when the terminal device performs measurement on the receiving beams.

As shown in fig. 2, the method includes:

and 210, dividing the multiple receiving beams into multiple receiving beam groups, where different measurement parameters are used among the multiple receiving beam groups, and the receiving beams in each receiving beam group use the same measurement parameter, where the measurement parameter is used for RRM measurement by the terminal device.

And 220, performing RRM measurements on each of the plurality of receive beam groups based on the measurement parameters of each of the plurality of receive beam groups.

In short, the terminal device first needs to divide the plurality of reception beams into a plurality of reception beam groups and then perform RRM measurement on each reception beam in the plurality of reception beam groups based on the measurement parameter of each reception beam group in the plurality of reception beam groups.

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

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

Optionally, before the terminal device divides the plurality of receiving beams into a plurality of receiving beam groups, obtaining a first parameter for dividing the plurality of receiving beams; and obtaining first measurements of the plurality of receive beams, the first measurements of the plurality of receive beams including a first measurement of each of the plurality of receive beams; the plurality of receive beams are then divided into the plurality of receive beam groups based on the first parameter and the first measurement of the plurality of receive beams.

For one embodiment, the first parameter is a first threshold value.

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

For example, the terminal device may divide the plurality of receive 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 plurality of receive beams, where the first receive beam group includes: the first measurement result of the plurality of receive beams is greater than or equal to the first threshold, and the second receive beam group comprises: the first measurement result of the plurality of receiving beams is smaller than the first threshold value.

In other words, the terminal device may divide all the reception beams into two reception beam groups according to the first threshold. And dividing the receiving beams corresponding to the measuring results which are greater than or equal to the first threshold into a first receiving beam group, and dividing the receiving beams corresponding to the measuring results which are less than the first threshold into a second receiving beam group.

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

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

It should be understood that the above threshold values are merely examples of the first threshold value. Embodiments of the invention are not limited in this respect.

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

For another example, the first threshold may be a threshold of another indicator.

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

Specifically, the terminal device may select a first reception beam group from the plurality of reception beams in order from high to low of the first measurement result, where the number of reception beams in the first reception beam group is the first value; the receive beams in the sequence of receive beams other than the first receive beam group are then determined to be a second receive beam group.

For example, the terminal device may rank the plurality of receive beams according to a first measurement result of the plurality of receive beams in an order from high to low or from low to high of the first measurement result, so as to form a receive beam sequence; the first group of receive beams is then selected from the sequence of receive beams in order from high to low of the first measurement.

In other words, the terminal device may arrange the measurement results of all beams in a descending order, wherein the reception beam corresponding to the first numerical measurement result with the best measurement result is divided into the first reception beam group, and the reception beams corresponding to the other measurement results are divided into the second reception beam group.

In the embodiment of the present invention, the terminal device may perform RRM measurement on each of the plurality of reception beams based on the measurement parameters of the plurality of reception beam groups. The following description is made with reference to fig. 3 and 4.

For example, in the case where the reception beam of the terminal device is divided into two beam groups, the reception beam in the first beam group may perform measurement once per T1 measurement GAPs, and the reception beam in the second beam group may perform measurement once per T2 measurement GAPs.

It is assumed that the terminal device has 4 receive beams.

As shown in fig. 3, the terminal device may divide the

beams

2, 3 into a beam group 1 and the beams 1, 4 into a beam group 2. Where beam 2 and beam 3 may have a measurement opportunity every 3 GAP periods, while beam 1 and beam 4 have a measurement opportunity every 6 GPA periods.

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

divide beams

1, 3, 4 into beam group 2. Where beam 2 may have a measurement opportunity every 2 GAP periods, while beam 1, beam 3, and beam 4 have a measurement opportunity every 6 GPA periods.

It can be seen that the measurement opportunity can be obtained for the beam 2 every 2 GAP periods as shown in fig. 4, and the measurement opportunities can be obtained for the

beams

1, 3, and 4 every 6 GAP periods, which relatively effectively ensures the measurement opportunity for the beam 2 with better received channel quality, and provides a certain measurement opportunity for the beam 1, the beam 3, and the beam 4.

It is noted that the terminal device may update the grouping of beam groups according to changes in the measurements of its different receive beams at different times.

For example, the example beams in FIG. 4 are grouped as {2}, {1, 3, 4 }; with a delay in time, the grouping of beams may be updated to {2, 4}, {1, 3}, assuming that the received signal quality of beam 4 may become better.

That is to say, the RRM measurement method according to the embodiment of the present invention effectively ensures the measurement opportunity of receiving the beam with better channel quality by grouping different received beams and measuring different beam groups using different measurement parameters, and provides a certain measurement opportunity for the beam with poorer signal reception quality.

Therefore, compared with a method of adopting equal measuring opportunities for each receiving beam, the method reduces the total measuring time overhead and ensures the measuring quality of the measuring beam with better receiving quality.

It should be understood that the measured parameters of the receive beam sets shown in fig. 3 and 4 are only exemplary descriptions, and embodiments of the present invention are not limited in particular.

An implementation of the terminal device acquiring the first parameter for dividing the plurality of reception beams is described below.

By way of example and not 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, where the notification message includes the first parameter.

Further, if the first parameter is the first value in the foregoing, before the terminal device receives the notification message, it is further required to send capability information of the terminal device to the network device, where the capability information includes the number of the multiple receiving beams, so that the network device determines the first value according to the capability information.

It should be understood that the first value is merely an exemplary illustration of the embodiment of the present invention, and the embodiment of the present invention is not limited thereto. For example, the first value may include a plurality of values.

Further, in order to further reasonably divide the plurality of receiving beams, the terminal device may further obtain a second measurement result of the plurality of receiving beam groups; the plurality of receive beam groups are regrouped according to the second measurement result.

In other words, the terminal device may perform measurement according to the measurement parameters of the multiple receive beam groups within a period of time, obtain a preliminary measurement result, and then regroup the multiple receive beam groups. Further, the measurement parameters between the respective beam groups can also be reset.

In addition, the measurement parameters are different among a plurality of receiving beam groups of the terminal equipment. Therefore, the terminal device needs to determine the measurement parameter of each of the plurality of reception beam groups before performing RRM measurement on each of the plurality of reception beam groups based on the measurement parameter of each of the plurality of reception beam groups.

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

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

For another example, the terminal device may set a plurality of measurement parameters in advance, configure the plurality of measurement parameters to the plurality of reception beam groups after the terminal device divides the plurality of reception beams into the plurality of reception beam groups, and notify the network device of the plurality of measurement parameters.
