Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, user equipment, and a base station for implementing discovery and measurement of cells with the same frequency.
Background
In a 3GPP (3rd Generation Partnership Project) protocol related to LTE (Long Term Evolution), there is a concept of a measurement GAP (GAP), in which a base station configures a measurement GAP to a UE (User Equipment), and the UE performs inter-frequency measurement and inter-system measurement using a configured periodic measurement window. Within these measurement windows, the data transmission of the UE may be interrupted. In the research on NR (New Radio, New air interface) in 3GPP, the concept of measurement gaps is used, and when UE needs to perform inter-frequency measurement or inter-system measurement, the network side may configure the measurement gaps to the UE, and when the UE needs to perform co-frequency measurement by hopping to a working frequency band, the network side may also configure the measurement gaps to the UE.
The measurement gaps are a series of time window configurations for the UE to perform cell discovery and measurement, and the UE may perform cell discovery and measurement using the time windows. In these time windows used for cell discovery and measurement, the data transmission of the UE may be interrupted to avoid the problem of data reception failure caused by the UE performing measurements on other operating frequency bands while transmitting data on the original operating frequency band.
In the RAN2 research of 3GPP on NR, a multi-beam (multi-beam) mechanism has been considered, and a base station may transmit and receive data by means of beam scanning (beam scanning) and obtain performance gain due to beam forming. Also, the UE can transmit and receive data based on the beam and obtain the gain due to beamforming. The communication between the UE and the base station will be established over a set of beam pairs, where the uplink is formed by the transmit beam of the UE and the receive beam of the base station and the downlink is formed by the receive beam of the UE and the transmit beam of the base station.
When the UE uses a multi-beam mechanism at the receiving end, that is, when the UE has multiple receiving beams, if the UE needs to perform co-frequency cell discovery and measurement in each receiving beam direction, the UE needs to perform the co-frequency cell discovery and measurement by using a method of transforming the receiving beam direction of the UE, and at this time, the UE needs to be configured with a measurement gap, and perform the co-frequency cell discovery and measurement based on different receiving beams by using the configured measurement gap.
If the UE utilizes the measurement gap to discover and measure the co-frequency cells based on different receiving beams, the UE can possibly discover all the co-frequency cells which can be discovered on each different receiving beam and perform corresponding measurement, but when the measurement is performed by utilizing the measurement gap, the data transmission between the UE and the current service base station can be interrupted, and the time for the co-frequency cell measurement can be prolonged by the UE to discover and measure the cells based on each different receiving beam; if the UE does not use the measurement gap to do the co-frequency cell discovery and measurement based on different receiving beams, the UE can only discover all the possibly discovered co-frequency cells on the receiving beam which is currently receiving data and do corresponding measurement, but the data transmission between the UE and the current service base station can not be interrupted, and the UE can avoid overlong co-frequency cell discovery and measurement time only by conducting the co-frequency cell discovery and measurement based on the receiving beam which is currently receiving data.
Based on the above benefit and disadvantage analysis, the UE does not have an explicit or reasonable selection criteria to decide whether to perform co-frequency cell discovery and measurement based on different receive beams.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for realizing same-frequency cell discovery and measurement, which is applied to UE (user equipment), and as shown in figure 1, the method comprises the following steps:
s11, the UE receives the indication whether the co-frequency cell discovery and measurement are needed based on different UE receiving beams or not, which is sent by the base station.
And S12, the UE selects to discover and measure the co-frequency cells based on different UE receiving beams or to discover and measure the co-frequency cells based on the currently working UE receiving beams according to the indication.
Wherein the currently operating UE receive beam may be a UE receive beam currently receiving data.
Specifically, the UE selects to perform intra-frequency cell discovery and measurement based on different UE receiving beams or perform intra-frequency cell discovery and measurement based on a currently operating UE receiving beam according to different received indications.
When the UE receives a measurement gap configured by the base station and dedicated for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, the UE selects to perform co-frequency cell discovery and measurement on the basis of the different UE receiving beams.
When UE receives a measurement gap which is configured by a base station and can be used for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, and the measurement gap can be used for a signaling indication that the UE performs the co-frequency cell discovery and measurement on different UE receiving beams, the UE selects to perform the co-frequency cell discovery and measurement on the basis of the different UE receiving beams.
When UE receives a measurement gap which is configured by a base station and can be used for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, and the measurement gap is not used for a signaling indication that the UE performs the co-frequency cell discovery and measurement on different UE receiving beams, the UE selects to perform the co-frequency cell discovery and measurement on the basis of the currently working UE receiving beam.
When the UE receives a measurement gap configured by the base station and used for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, and does not receive a signaling indication that the measurement gap can be used for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, the UE performs a preset default operation, wherein the default operation can be to select to perform co-frequency cell discovery and measurement on the basis of the currently working UE receiving beam or select to perform co-frequency cell discovery and measurement on the basis of different UE receiving beams.
The base station configures a measurement gap for the UE, where the measurement gap is used for the UE to perform co-frequency cell discovery and measurement on different UE receiving beams, and the UE may also perform other measurements by using the measurement gap, for example: the same-frequency measurement, different-frequency measurement or different-system measurement performed by skipping the working frequency band is required.
The measurement gap may be configured by the base station through RRC (Radio Resource Control) dedicated signaling, for example: the configuration is performed through an RRC connection reconfiguration message.
The signaling indication may be sent to the UE by the base station through RRC dedicated signaling, for example, an RRC connection reconfiguration message, or sent to the UE by broadcasting.
In addition, if the base station does not configure a measurement gap for the UE, which is dedicated for the UE to perform the co-frequency cell discovery and measurement on different UE reception beams, or configure a measurement gap for the UE, which is dedicated for the UE to perform the co-frequency cell discovery and measurement on different UE reception beams, the UE performs the co-frequency cell discovery and measurement only on the basis of the currently operating UE reception beam.
According to the method for realizing the same-frequency cell discovery and measurement provided by the embodiment of the invention, the UE can select to discover and measure the same-frequency cell based on different UE receiving beams or to discover and measure the same-frequency cell based on the currently working UE receiving beam according to the indication of the base station, the configuration of the measurement gap required by the same-frequency cell discovery and measurement of different UE receiving beams has flexibility and can be configured as required, so that the requirements of the base station on the same-frequency cell discovery and measurement are met.

and S21, the base station judges whether the preset requirement is met or not or meets the preset judgment condition.
S22, when the preset requirement is judged to be met or the preset judgment condition is met, the base station sends an indication whether the co-frequency cell discovery and measurement are needed based on different UE receiving beams to the UE.
Optionally, the predetermined requirement may be: the base station hopes that the UE does not cause the interruption of data transmission when the UE does the same-frequency cell discovery and measurement, and allows the UE to only do the same-frequency cell discovery and measurement on the currently working UE receiving beam; when the base station has the predetermined requirement, the base station sends an indication to the UE that intra-frequency cell discovery and measurement based on different UE reception beams are not required.
Optionally, the predetermined requirement may be: the base station hopes that the UE performs same-frequency cell discovery and measurement on different receiving beams of the UE, and allows the UE to cause interruption of data transmission when performing same-frequency cell discovery and measurement; when the base station has the predetermined requirement, the base station sends an indication to the UE that intra-frequency cell discovery and measurement based on different UE receiving beams are required.
Optionally, the preset determination condition may be: the base station finds that the measurement report result of the UE which is only based on the UE receiving beam which is working at present and does the same frequency cell discovery and measurement can not meet the measurement requirement; when the base station meets the preset judgment condition, the base station sends an indication that the co-frequency cell discovery and measurement are required to be carried out based on different UE receiving beams to the UE.
Wherein the failing to meet the measurement requirement may include: the measurement report formed by the measurement of the co-frequency cell by the UE based on the currently working receiving beam is not received within the preset time; or
In the results obtained by measuring the same-frequency cells on the currently working UE receiving beams reported by the UE, the number of reported cells does not exceed the preset threshold value of the number of reported cells; or
