Description
Technical field
The present invention relates to wireless communication technology field more particularly to a kind of discovery of co-frequency cell and measurement method, device, use
Family equipment and base station.
Background technique
In 3GPP (3rd Generation Partnership Project, third generation partner program) about LTE
There are the concept of measurement gap (GAP), base station allocating and measuring gap in the agreement of (Long Term Evolution, long term evolution)
It gives UE (User Equipment, user equipment), UE carries out different-frequency measure and different system using the periodic measurement window configured
Unified test amount.In these measurement windows, the data transmission of UE can be interrupted.In 3GPP about NR's (New Radio, newly eat dishes without rice or wine)
The concept in measurement gap is continued to use in research, when UE needs to do different-frequency measure or isosystem measurement, network side can be configured
Gap is measured to UE, network side can also configure measurement when UE needs carry out common frequency measurement by way of jumping working band
Gap is to UE.
Above-mentioned measurement gap is a series of time windows configuration that cell discovery and measurement are done for UE, when UE can utilize these
Between window carry out cell discovery and measurement.In the time window that these are used as that cell finds and measures, the data of UE transmit meeting
It is interrupted, to avoid data of data caused by being transmitted on former working frequency range but UE on other working frequency range measuring
Reception failure problem.
In RAN2 research of the 3GPP about NR, it has to be considered that the mechanism of multi-beam (multi-beam), base station can
Sending and receiving and obtaining wave beam forming bring for data is carried out in a manner of through beam scanning (beam sweeping)
It can gain.Same UE can also carry out sending and receiving and obtaining wave beam forming bring gain for data based on wave beam.UE and
Communication between base station will be built upon on one group of wave beam pair, wherein uplink by UE transmission wave beam and base station reception
Wave beam is constituted, and downlink is made of the transmission wave beam of the reception wave beam of UE and base station.
When UE receiving end use multi-beam mechanism, i.e. when UE has multiple reception wave beams, connect if necessary to UE each
It receives and does co-frequency cell discovery and measurement on beam direction, then UE is needed to carry out by using the mode that transformation UE receives beam direction
Co-frequency cell discovery and measurement at this point, UE needs are configured to measure gap, and are carried out using the measurement gap configured based on not
With the co-frequency cell discovery and measurement for receiving wave beam.
However, if UE is regardless of being based on currently just when UE has multiple reception wave beams and is configured with measurement gap by base station
Whether meet the requirement that base station reports measurement in the result of the progress co-frequency cell discovery of reception wave beam and measurement that receive data,
Co-frequency cells discovery and measurement based on different reception wave beams directly all are done using measurement gap, then UE and Current Serving BTS
Between data transmission can be interrupted, and UE cell discovery carried out based on each different reception wave beam and measurement can extend it is same
Time needed for frequency cell measurement.

Source control) signal deployment.
Wherein, the preset time can be configured by RRC signaling by base station or be carried out by itself preset.Such as:
5ms, 10ms, 20ms, 40ms, 80ms, 160ms or 200ms etc..
S12, when determine need based on different receptions wave beams carry out co-frequency cell discovery and measure when, UE is in different received waves
Co-frequency cell discovery and measurement are carried out using the measurement gap that base station is configured on beam, otherwise UE continues to be based on being currently being received
The reception wave beam of data carries out co-frequency cell discovery and measurement.
Co-frequency cell discovery provided in an embodiment of the present invention and measurement method, when UE has multiple reception wave beams and is matched by base station
When having set measurement gap, first judges whether to need to carry out co-frequency cell discovery and measurement based on different reception wave beams, only have
Co-frequency cell discovery and measurement just are carried out using the measurement gap that base station is configured on different reception wave beams when needing, and not
When needing to carry out co-frequency cell discovery and measurement based on different reception wave beams, continue based on the received wave that data are currently being received
The discovery of the co-frequency cell Shu Jinhang and measurement.Due to UE be based only on be currently being received data reception wave beam carry out co-frequency cell hair
It now can be to avoid the discovery of too long co-frequency cell and time of measuring, so as to have multiple reception wave beams in UE and by base with measurement
Station is configured under the scene in measurement gap shortens the time needed for UE carries out co-frequency cell measurement to a certain extent, and avoids not
Necessary measurement gap occupies.
The embodiment of the present invention provides another co-frequency cell discovery and measurement method, the method are applied to base station, such as Fig. 2
It is shown, which comprises
S21, the measurement gap that can be used for carrying out co-frequency cell discovery and measurement based on different reception wave beams for UE configuration, with
And maximum measurement cell number, maximum reporting subdistrict number or the received wave that data are currently being received based on UE under current frequency point
The minimum cell number that should be found on beam, so that UE is according to the maximum measurement cell number, maximum reporting subdistrict number or most
Small number of cells judges whether to need to be based on different reception wave beams using the measurement gap to carry out co-frequency cell discovery and measurement.
Optionally, base station can also configure the default cell quality threshold that the cell quality of its discovery should be higher than that for UE, with
And judge whether that the reception wave beam discovery that data can be currently being received based on UE is small more than or equal to the maximum measurement
The quality of area's number, maximum reporting subdistrict number or minimum cell number is higher than needed for the cell of the default cell quality threshold
Preset time.

First configuration unit, for can be used for carrying out the survey of co-frequency cell discovery and measurement based on different reception wave beams for UE configuration
It measures the maximum measurement cell number under gap, and current frequency point, maximum reporting subdistrict number or number is currently being received based on UE
According to reception wave beam on the minimum cell number that should find so that UE reported according to the maximum measurement cell number, maximum it is small
Area's number or minimum cell number judge whether to need to be based on different reception wave beams using the measurement gap to carry out co-frequency cell
It was found that and measurement.
14. device according to claim 13, which is characterized in that described device further include:
Second configuration unit, the default cell quality threshold that the cell quality for configuring its discovery for UE should be higher than that, and sentence
The disconnected reception wave beam discovery that data whether can be currently being received based on UE be more than or equal to the maximum measurement cell number,
The quality of maximum reporting subdistrict number or minimum cell number, which is higher than needed for the cell of the default cell quality threshold, to be preset
Time.
15. a kind of user equipment, which is characterized in that the user equipment includes as described in any one of claim 8 to 12
Co-frequency cell discovery and measuring device.
16. a kind of base station, which is characterized in that the base station includes co-frequency cell discovery according to claim 13 or 14 and surveys
Measure device.
