Description

Measuring method and measuring device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a measuring method and a measuring device.

Background

As communication technology advances, mobility of terminal devices increases. The related protocols of the third generation partnership project (3rd generation partnership project,3GPP) currently define that radio resource management (radio resource management, RRM) L3 mobility management needs to be performed when the terminal device is in a connected state, where measurements of searches for co-frequency, inter-frequency and inter-system neighbors are mainly involved. The terminal equipment needs to determine a new neighbor cell and complete reporting of a measurement result in a corresponding time requirement, and performs corresponding mobility management.

The measurement process of the terminal device involves a process of measuring radio resource control (radio resource control, RRC) reconfiguration, bandwidth part (BWP) handover, cell handover, or the like. When the same frequency point of the terminal equipment changes, the measurement result acquisition time of the same frequency and different frequency adjacent cells of the terminal equipment is relatively long, for example, in a DXR1.28 scene, the cell information acquisition delay of the same frequency point exceeds about 10s, and the delay size has a large influence relative to the overall performance of the network.

Therefore, a method for reducing the acquisition time of the neighbor cell measurement result of the terminal device and improving the mobility performance of the terminal device is needed.

Disclosure of Invention

The embodiment of the application provides a measuring method and a measuring device, and the measuring method can reduce the acquisition time of a terminal equipment neighbor cell measuring result and improve the mobile performance of the terminal equipment under the scene that the same frequency point of the terminal equipment changes.

In a first aspect, a measurement method is provided, which may be performed by a terminal device, or may also be performed by a chip or a circuit of the terminal device, which is not particularly limited by the present application. For convenience of description, the communication apparatus in the present application will be described by taking a terminal device as an example.

The method comprises the following steps:

the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point, and the first frequency point is a different frequency point before the same frequency point of the terminal equipment is switched; multiplexing the first information into a same-frequency neighbor cell information list of the first frequency point after the same-frequency point switching by the terminal equipment; the terminal equipment multiplexes second information into a different-frequency point adjacent region information list of a second frequency point after the same-frequency point switching, wherein the first information is adjacent region information of the first frequency point before the same-frequency point switching of the terminal equipment, and the second information is adjacent region information of the second frequency point before the same-frequency point switching of the terminal equipment.

According to the method provided by the application, in the scene that the same frequency point of the terminal equipment changes, the terminal equipment can directly multiplex the adjacent cell information of the corresponding frequency point before the same frequency point changes. Compared with the prior art, under the condition that the same frequency point of the terminal equipment changes, the terminal equipment does not need to search and acquire SSB index corresponding to the adjacent cell of the changed frequency point, so that the time delay of reporting the measurement result of the adjacent cell of the terminal equipment is shortened, and the overall performance of the network is improved.

It should be understood that the first frequency point in the present application may include one or more frequency points, and the second frequency point may include one or more frequency points. The first information may be neighbor information of a first frequency point (one or more frequency points) before the same frequency point switching of the terminal device, and the second information may be neighbor information of a second frequency point (one or more frequency points) before the same frequency point switching of the terminal device.

In combination with the first aspect, in some possible implementation manners, the second frequency point may include a same frequency point and a different frequency point of the terminal device, and when the same frequency point of the terminal device is switched, that is, the same frequency point of the terminal device is switched from the second frequency point to the first frequency point, the same frequency point in the second frequency point is updated to the different frequency point of the terminal device. After the same frequency point is switched, in the measurement configuration information acquired by the terminal equipment, the different frequency point in the second frequency point before switching may still be the different frequency point of the terminal equipment after switching. In the information multiplexing process, the same-frequency point adjacent region information of the same-frequency point of the terminal equipment in the second frequency point before switching is multiplexed into the different-frequency point adjacent region information list of the frequency point after switching, and the different-frequency point adjacent region information of the different-frequency point of the terminal equipment in the second frequency point before switching is multiplexed into the different-frequency point adjacent region information list of the frequency point after switching.

With reference to the first aspect, in some possible implementations, the neighboring cells of the first frequency point include a first cell, the neighboring cells of the second frequency point include a second cell, and the first cell and the second cell satisfy a first condition, where the first condition includes: and in the first time period, the terminal equipment finishes cell measurement reporting on the first cell and the second cell or the terminal equipment finishes identification of the first cell and the second cell, and the signal intensity of the first cell and the second cell relative to the terminal equipment is larger than or equal to a first threshold value.

Based on the above technical solution, in a scene that the same frequency point of the terminal device changes, the neighboring cells of the first frequency point and the neighboring cells of the second frequency point both need to satisfy a first condition (or a condition called a known neighboring cell), in a first period of time, the terminal device completes cell measurement reporting or cell identification on the first cell and the second cell, and signal strengths of the first cell and the second cell relative to the terminal device are greater than or equal to a first threshold. The terminal equipment determines that the first cell and the second cell meet a first condition, and directly multiplexes adjacent cell information of the corresponding frequency point, so that time delay caused by the same frequency point change of the terminal equipment is reduced.

It should be understood that the neighboring cells of the first frequency point and the second frequency point include one or more cells, that is, the first cell and the second cell each represent a type of cell, that is, the first cell represents a neighboring cell of the first frequency point, the second cell represents a neighboring cell of the second frequency point, and there is no limitation on the number of neighboring cells by both the first cell and the second cell.

It should also be understood that the first threshold may be preconfigured by the system, or determined by the terminal device itself, or indicated by the network device, which is not particularly limited in this regard.

With reference to the first aspect, in some possible implementations, the first information includes measurement information and/or frequency point information of the first cell, and the second information includes measurement information and/or frequency point information of the second cell, where the measurement information includes one or more of the following: timing information, measurements, synchronization signal block index SSB index, automatic gain control AGC shift information.

Based on the technical scheme, the terminal equipment multiplexes the second information into the different-frequency point neighbor information list of the second frequency point after the same-frequency point switching in the same-frequency neighbor information list of the first frequency point after the same-frequency point switching. The first information includes information of a first cell (or referred to as neighbor information of the first frequency point) when the first frequency point is a different frequency point of the terminal device, the second information includes information of a second cell (or referred to as neighbor information of the second frequency point) when the second frequency point is a same frequency point of the terminal device, and the information of the first cell and the information of the second cell may include one or more of timing information, measurement value, synchronization signal block index SSB index, and frequency point information. The terminal equipment can directly multiplex the original neighbor information without searching and SSB index acquisition, thereby reducing the time delay caused by the same frequency point change of the terminal equipment.

With reference to the first aspect, in some possible implementations, the first period is a period before the same frequency point of the terminal device is switched from the second frequency point to the first frequency point.

It should be understood that the first time period may be any continuous time before the same frequency point of the terminal device is switched from the second frequency point to the first frequency point. Before the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point, the terminal equipment finishes cell measurement reporting on the first cell and the second cell or finishes cell identification on the first cell and the second cell, and the signal intensity of the first cell and the second cell relative to the terminal equipment is larger than or equal to a first threshold value.

With reference to the first aspect, in some possible implementations, the first condition further includes: the first measurement configuration parameter is the same as the second measurement configuration parameter, and both the first measurement configuration parameter and the second measurement configuration parameter include at least one of:

frequency point information, cell identification information, synchronization signal block SSB information,

The first measurement configuration parameter is a measurement configuration parameter of the first frequency point and the second frequency point before the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point, and the second measurement configuration parameter is a measurement configuration parameter of the first frequency point and the second frequency point after the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point.

Based on the above technical solution, the first conditions that the first cell and the second cell need to satisfy further include: the first measurement configuration parameter is the same as the second measurement configuration parameter. That is, before the same-frequency point of the terminal equipment is switched, the measurement parameters of the first frequency point and the second frequency point are the same as the measurement configuration parameters of the first frequency point and the second frequency point after the same-frequency point of the terminal equipment is switched. The measurement configuration parameters may include one or more of frequency point information, cell identification information, synchronization signal block SSB information.

In a second aspect, there is provided a measurement method comprising: the terminal equipment adds the first frequency point into the same frequency point of the terminal equipment; the terminal equipment multiplexes the first information into a same-frequency neighbor information list of a first frequency point which is added as a same-frequency point of the terminal equipment, wherein before the terminal equipment adds the first frequency point as the same-frequency point of the terminal equipment, the first frequency point is a different-frequency point of the terminal equipment, the same-frequency point of the terminal equipment comprises a second frequency point, and the first information is neighbor information when the first frequency point is the different-frequency point of the terminal equipment.

According to the method provided by the application, the terminal equipment can add a different frequency point as the same frequency point of the terminal equipment, namely, the same frequency point of the terminal equipment can comprise one or more. Similarly, the terminal equipment can directly multiplex the adjacent cell information of the different frequency point into the same-frequency adjacent cell information list of the frequency point after being added as the same frequency point, and the terminal equipment does not need to measure and acquire the adjacent cell corresponding to the frequency point, so that the time delay required by adding the same frequency point of the terminal equipment is reduced, and the overall performance of the network is improved.

With reference to the second aspect, in some possible implementations, the neighboring cells of the first frequency point include a first cell, and the first cell satisfies a first condition, where the first condition includes: and in the first time period, the terminal equipment completes cell measurement reporting of the first cell or the terminal equipment completes identification of the first cell, and the signal strength of the first cell relative to the terminal equipment is larger than or equal to a first threshold value.

Based on the above technical solution, in a scene where the same frequency point of the terminal device changes (for example, a scene where the terminal device adds the same frequency point), the neighboring cell of the first frequency point satisfies a first condition (or a condition called a known neighboring cell), the terminal device completes cell measurement reporting on the first cell or completes cell identification on the first cell in a first period of time, and the signal strength of the first cell relative to the terminal device is greater than or equal to a first threshold. The terminal equipment determines that the first cell meets the first condition, and directly multiplexes the adjacent cell information when the first frequency point is the different frequency point of the terminal equipment, thereby improving the overall performance of the network.

With reference to the second aspect, in some possible implementations, the first information includes measurement information and/or frequency point information of a first cell, where the measurement information of the first cell includes one or more of the following: timing information, measurements, synchronization signal block index SSB index, automatic gain control AGC shift information.

Based on the technical scheme, the terminal equipment multiplexes the first information into the same-frequency neighbor information list of the first frequency point which becomes the same-frequency point of the terminal equipment. The first information includes information of a first cell (or referred to as neighbor information of the first frequency point) when the first frequency point is a different frequency point of the terminal device, and the information of the first cell may include one or more of timing information, a measured value, a synchronization signal block index SSB index, and frequency point information. The terminal equipment can directly multiplex the adjacent cell information when the first frequency point is the different frequency point, and does not need to search and acquire SSB index, thereby improving the overall performance of the network.

With reference to the second aspect, in some possible implementations, the first period is a period before the terminal device adds the first frequency point to be the same frequency point of the terminal device.

It should be understood that the first time period may be any continuous time before the terminal device adds the first frequency point to the same frequency point. When the first frequency point is a different frequency point of the terminal equipment, the terminal equipment finishes cell measurement reporting on the first cell or finishes cell identification on the first cell, and when the first frequency point is the different frequency point of the terminal equipment and the first frequency point is the same frequency point of the terminal equipment, the signal strength of the first cell relative to the terminal equipment is larger than or equal to a first threshold value.

The terminal device may communicate with the core network via a radio access network (radio access network, RAN) to exchange voice and/or data with the RAN. For example, the terminal device may be a handheld device having a wireless connection function, an in-vehicle device, a vehicle user device, or the like. Currently, examples of some terminal devices are: a mobile phone, tablet, cellular phone, cordless phone, session initiation protocol (session initiation protocol, SIP) phone, wireless local loop (wireless local loop, WLL) station, personal Digital Assistant (PDA), laptop, palmtop, mobile internet device (mobile INTERNET DEVICE, MID), wearable device, virtual Reality (VR) device, augmented reality (augmented reality, AR) device, wireless terminal in industrial control (industrial control), wireless terminal in unmanned (SELF DRIVING), wireless terminal in teleoperation (remote medical surgery), wireless terminal in smart grid (SMART GRID), wireless terminal in transportation security (transportation safety), wireless terminal in smart city (SMART CITY), wireless terminal in smart home (smart home), artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) terminal, and the like, without limitation to the embodiments of the present application.

Fig. 1 is a schematic diagram of a network architecture of a communication system according to an embodiment of the present application.

In the embodiment of the present application, a scenario in the communication system shown in fig. 1 is taken as an example for illustration. The method in the embodiment of the application can also be applied to other mobile communication systems, and the corresponding names can also be replaced by the names of the corresponding functions in other mobile communication systems, so that the application is not particularly limited.

As shown in fig. 1, the communication system includes a terminal device 110, a network device 120, a network device 130, and a network device 140.

It should be understood that in the communication system, the communication areas are divided according to areas, each communication area should include one or more network devices, the area covered by the network device signal is a cell corresponding to the current network device, and the network device may provide services for one or more terminal devices in the corresponding cell.

As shown in fig. 1, the cell corresponding to the network device 120 is a source cell, the cell corresponding to the network device 130 is a target cell, and the cell corresponding to the network device 140 is a neighboring cell (or referred to as a neighbor cell). Terminal device 110 initially establishes a connection with network device 120. Due to the movement of the location of the terminal device 110, the quality of service of the source cell relative to the terminal device 110 is reduced until the source cell cannot meet the requirements of the terminal device 110 for communication quality. At this time, the terminal device 110 needs to perform cell switching, and during the period of switching cells, the terminal device 110 will remain connected with both the network device 120 and the network device 130 until receiving the signaling sent by the network device 130, disconnect the connection with the network device 120, and release the source cell to complete cell switching, i.e. switch from the source cell to the target cell.

In order to facilitate understanding of the technical solutions in the embodiments of the present application, a part of the terms in the embodiments of the present application will be explained below for understanding by those skilled in the art.

1. Bandwidth part (BWP)

BWP consists of a set of consecutive physical resource blocks (physical resource blocks, PRBs). The PRBs are selected from a set of contiguous common resource blocks (common resource blocks, CRBs). Wherein each BWP may be different numerology. Different numerology correspond to different subcarrier spacing, symbol duration, cyclic prefix.

Wherein, the UE can configure 4 BWP at maximum in uplink/downlink transmission DL, wherein only one BWP is in active state at each specific moment. The BWP may be selected or switched according to the operation of the BWP in the 3GPP protocol in several ways.

(1) Selection or handover of BWP by RRC signal

(2) Activation of BWP by BWP indicator in DCI 0_1 (UL) and DCI 1_0 (DL)

(3) Switching BWP by its deactivation timer

(4) Selection or switching of BWP by MAC CE

The BWP can be selected or switched by using several of the above. Wherein a specific BWP will become active in response to various conditions in the call processing, i.e. changes in the user traffic demand.

2. Radio resource management (radio resource management, RRM)

RRM measurements may also be referred to as mobility measurements. In an LTE communication system, RRM measurements are measurements based on Common Reference Signals (CRS), including measurements of reference signal received power (REFERENCE SIGNALRECEIVED power, RSRP), reference signal received quality (REFERENCE SIGNAL RECEIVED quality, RSRQ), and signal to noise AND INTERFERENCE ratio (SINR). In an NR communication system, RRM measurements include two types: measurement based on synchronization signal blocks (synchronized resource block, SSB) and measurement based on reference signal channel state information (CSI-RS) (channel-stateinformation-REFERENCE SIGNAL). If SSB-based, the RRM measurements include measurements of synchronization signal-based reference signal received power (synchronization signal based REFERENCE SIGNALRECEIVED powerSS-RSRP), synchronization signal-based reference signal received quality (synchronization signalbased REFERENCE SIGNAL RECEIVED quality, SS-RSRQ), and synchronization signal-based signal-to-interference and noise ratio (synchronization signal based signal to noise AND INTERFERENCE ratio, SS-SINR). If based on the CSI-RS measurements, the RRM measurements include the measurements of CSI-RSRP, CSI-RSRQ, and CSI-SINR.

RRM measurements, such as L3 RSRP measurements, are divided into co-frequency measurements, inter-frequency measurements, and inter-system measurements. The same frequency measurement means that the measured cells are on the same carrier. And inter-frequency measurement or inter-system measurement means that the measured cell is not on one carrier.

In the prior art, due to the movement of the position of the terminal equipment, when the service signal quality of the source service cell does not meet the requirement of the terminal equipment, the terminal equipment needs to select a target cell with better signal quality to provide high-quality communication service for the terminal equipment.

According to the difference of frequency bands of the service cell and the target neighbor cell, the cell switching can be divided into common-frequency switching and different-frequency switching. The same frequency switching can be used for indicating that the target cell and the current serving cell use the same radio frequency carrier frequency; inter-frequency handover may be used to indicate that the target cell uses a different radio frequency carrier frequency than the current serving cell.

When the terminal device is in a connected state, RRM L3 mobility management needs to be performed, which involves searching and measurement of co-frequency, inter-frequency and inter-system neighbors. The terminal equipment needs to find a new neighbor cell and complete reporting of a measurement result in a corresponding time requirement, and performs corresponding mobility management after reporting the measurement result. The measurement process of the terminal device mainly involves the processes of RRC reconfiguration, BWP handover, cell handover, and the like.

In the prior art, after the BWP of the terminal equipment is switched and the same-frequency neighbor cell is changed due to the SSB frequency point. The definition of the new cell identified by the terminal device in the current protocol comprises the time required by the processes of searching, measuring, obtaining SSB index and the like.

Or the original SSB frequency point #0 of the terminal equipment is the same frequency point, and the SSB frequency point #0 is not the same frequency point of the terminal equipment any more due to BWP switching of the terminal equipment. If the measurement object configuration still exists, the terminal device measures the acquisition time delay of the inter-frequency neighbor cell according to the inter-frequency, wherein the time delay comprises the time required by searching, measuring and acquiring the SSB index.

It can be understood that, after the co-frequency point of the terminal device changes, the terminal device needs to further search, measure and SSB index to obtain measurement results of co-frequency and inter-frequency neighbor cells, which further results in a longer acquisition time of the terminal device and has a larger influence on the mobility switching performance of the terminal device.

Based on the technical problems, the embodiment of the application provides a measurement method, which avoids the time of searching terminal equipment and acquiring SSB index in a scene of changing the same frequency point, accelerates the reporting of the measurement result of the terminal equipment and improves the mobility switching performance of the terminal equipment.

Fig. 2 is a schematic flow chart diagram of a measurement method according to an embodiment of the present application.

It should be noted that, the communication apparatus in fig. 2 specifically takes a terminal device as an example, and the measurement method provided by the present application is described in detail.

As shown in fig. 2, the method comprises the steps of:

s201, the same frequency point of the communication device (e.g., terminal device) is switched from the second frequency point to the first frequency point.

Before the same frequency point of the terminal equipment is switched, the first frequency point is the different frequency point of the terminal equipment, and the second frequency point is the same frequency point of the terminal equipment.

It should be understood that the scene of the change of the same frequency point of the terminal device may be the change of the same frequency point of the terminal device caused by the activation BWP switch of the terminal device, or the change of the service frequency point caused by the cell switch corresponding to the terminal device, or the addition of the service frequency point in the carrier aggregation CA scene, etc., which is not specifically limited in this application. In the future, the method shown in fig. 2 of the present application can be applied to a scenario where the same frequency point of the terminal device changes.

S202, the communication device multiplexes the first information into a same-frequency point neighbor information list of the first frequency point after the same-frequency point is switched.

The first information is neighbor information of a first frequency point before the same frequency point of the terminal equipment is switched, or may be called as different frequency neighbor information of the first frequency point.

Specifically, when the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point, the terminal equipment can multiplex the neighbor information when the first frequency point is the different frequency point of the terminal equipment into a neighbor information list of which the switched first frequency point is the same frequency point of the terminal equipment.

It should be understood that the first information is multiplexed into the same-frequency point neighboring cell information list of the first frequency point after switching, or may be referred to as that the first information is inherited into the same-frequency point neighboring cell information list of the first frequency point after switching, or may be referred to as that the first information is updated into the same-frequency point neighboring cell information list of the first frequency point after switching. That is, the terminal device stores the first information in the same-frequency point neighboring cell information list of the switched first frequency point, and can be directly used by the terminal device.

In one possible implementation manner, the neighboring cells of the first frequency point include a first cell, the first information includes measurement information and/or frequency point information of the neighboring cells (first cells) of the first frequency point when the first frequency point is a different frequency point of the terminal device, where the measurement information of the first cell includes one or more of the following: timing information, measurements, synchronization signal block index SSB index, automatic gain control (automatic gain control, AGC) gear information. The terminal equipment multiplexes the first information into the same-frequency point adjacent cell information list of the first frequency point after switching, namely, the terminal equipment multiplexes the measurement information of the first cell into the same-frequency adjacent cell information list of the first frequency point from the different-frequency adjacent cell information list of the first frequency point.

And S203, multiplexing the second information into a different frequency point adjacent region information list of the second frequency point by the communication device.

The second information is neighbor information of the second frequency point when the same frequency point is the second frequency point before the same frequency point of the terminal equipment is switched, or may be referred to as same frequency neighbor information of the second frequency point.

Specifically, the same frequency point of the terminal equipment is switched from a second frequency point to a first frequency point, the second frequency point is changed from the same frequency point of the terminal equipment to a different frequency point of the terminal equipment, and then the terminal equipment multiplexes the second information into a different frequency point adjacent region information list of the second frequency point after the same frequency point is switched.

It should be understood that the second information is multiplexed into the inter-frequency point neighbor information list of the second frequency point, or may be referred to as that the second information is inherited into the inter-frequency point neighbor information list of the second frequency point, or may be referred to as that the second information is updated into the inter-frequency point neighbor information list of the second frequency point. That is, the terminal device stores the second information in the different frequency point neighboring cell information list of the second frequency point after switching, and can be directly used by the terminal device.

In a possible implementation manner, the neighboring cells of the second frequency point include a second cell, the second information includes measurement information and/or frequency point information of the neighboring cells (second cells) of the second frequency point when the second frequency point is a different frequency point of the terminal device, where the measurement information of the second cell includes one or more of the following: timing information, measurement values, synchronization signal block index SSB index, AGC shift information. The terminal equipment multiplexes the second information into a different frequency point adjacent cell information list of the second frequency point after switching, namely, the terminal equipment multiplexes the measurement information of the second cell from the same frequency adjacent cell information list of the second frequency point into the different frequency adjacent cell information list of the second frequency point.

In another possible implementation manner, the neighboring cells of the first frequency point include a first cell, the neighboring cells of the second frequency point include a second cell, and the first cell and the second cell need to satisfy the first condition. Wherein the first condition includes:

In the first time period, the terminal equipment finishes the cell measurement report of the first cell and the second cell or the terminal equipment finishes the identification of the first cell and the second cell,

And, a step of, in the first embodiment,

The signal strengths of the first cell and the second cell with respect to the terminal device are greater than or equal to a first threshold.

It should be appreciated that the signal strengths of the first cell and the second cell both before and after the co-channel point handover of the terminal device are greater than or equal to the first threshold. The first cell may be one cell or a plurality of different cells, and the second cell may be one cell or a plurality of different cells, which is not limited to the present application. The first cell and the second cell may be the same cell or different cells, which is not particularly limited in the present application.

The first threshold may be determined by the terminal device itself, or predefined by the system, or determined by some indication information, which is not specifically limited in the present application.

It should be understood that the first period may be a period of time before the same frequency point of the terminal device is switched from the second frequency point to the first frequency point, and the length of the first period is not specifically limited in the present application.

As an example, before the same frequency point of the terminal device changes, the frequency point #0 is the same frequency point of the terminal device, the neighboring cell of the frequency point #0 includes the cell #0, the frequency point #1 is a different frequency point of the terminal device, the neighboring cell of the frequency point #1 includes the cell #1, and the cell #0 and the cell #1 complete the cell measurement reporting of the cell #0 and the cell #1 or the terminal device identifies the cell #0 and the cell #1 in a certain continuous time period before the same frequency point of the terminal device changes. Meanwhile, the signal strength of the cell #1 and the cell #0 with respect to the terminal device before the terminal device co-frequency point is changed and the signal strength with respect to the terminal device after the terminal device co-frequency point is changed are both greater than or equal to a certain threshold (e.g., a first threshold).

In another possible implementation, the first condition further includes: the first measurement configuration parameter is the same as the second measurement configuration parameter, the first measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point before the same frequency point of the terminal equipment is switched, and the second measurement configuration parameter is the measurement configuration parameter of the first frequency point and the second frequency point after the same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point.

Optionally, the first measurement configuration parameter and the second measurement configuration parameter comprise one or more of: frequency point information, cell identification information, and synchronization signal block SSB information.

It should be understood that, before and after the same frequency point of the terminal device changes, the measurement configuration parameters of the same frequency point are unchanged, and then the neighboring cell of the frequency point can be regarded as a known neighboring cell of the terminal device.

As an example, before the same frequency point of the terminal device is switched, the frequency point #a is the same frequency point of the terminal device, and the frequency point #b is a different frequency point of the terminal device. The same frequency point of the terminal equipment is switched from the frequency point #A to the frequency point #B, after the switching, the frequency point #B is the same frequency point of the terminal equipment, and the frequency point #A is a different frequency point of the terminal equipment. Before and after switching of the terminal equipment, the measurement configuration parameters of the frequency point #A are the same as those of the frequency point #A after switching; before and after the terminal equipment is switched, the measurement configuration parameters of the frequency point #B are the same as those of the frequency point #B after the switching, namely the adjacent cell corresponding to the frequency point #A and the adjacent cell corresponding to the frequency point #B are known adjacent cells of the terminal equipment.

It should be understood that, before the same-frequency point of the terminal device is switched, the second frequency point may include the same-frequency point of the terminal device and an different-frequency point of the terminal device, and when the same-frequency point of the terminal device is switched to the first frequency point, the same-frequency point in the second frequency point is switched to the different-frequency point of the terminal device. After the handover, in the measurement configuration information acquired by the terminal device, the inter-frequency point in the second frequency point may still be the inter-frequency point of the terminal device. In the information multiplexing process, the same-frequency point adjacent region information of the same-frequency point of the terminal equipment in the second frequency point before switching is multiplexed into the different-frequency point adjacent region information list of the frequency point after switching, and the different-frequency point adjacent region information of the different-frequency point of the terminal equipment in the second frequency point before switching is multiplexed into the different-frequency point adjacent region information list of the frequency point after switching.

As an example, when the first frequency point includes a frequency point #0, and the second frequency point includes a frequency point #1 and a frequency point #2, where the frequency point #0 is a different frequency point before the same frequency point switching of the terminal device, the frequency point #1 is the same frequency point before the same frequency point switching of the terminal device, and the frequency point #2 is a different frequency point before the same frequency point switching of the terminal device. The same frequency point of the terminal equipment is switched from the second frequency point to the first frequency point, which can be understood that the same frequency point of the terminal equipment is switched from the frequency point #1 to the frequency point #0, and the frequency point #2 after the switching is still the different frequency point of the terminal equipment. The terminal equipment can multiplex the adjacent cell information when the frequency point #1 is the different frequency point of the terminal equipment into an adjacent cell information list when the frequency point #1 is the same frequency point of the terminal equipment; the terminal device may multiplex the neighbor information when the frequency point #0 is the different frequency point into the neighbor information list when the frequency point #0 is the same frequency point of the terminal device. After the same-frequency point of the terminal device is switched, the frequency point #0 is the same-frequency point of the terminal device, and when the measurement configuration information of the terminal device includes the frequency point #2, the terminal device may continue to multiplex the different-frequency neighbor information of the frequency point #2 before the same-frequency point is switched into the different-frequency neighbor information of the frequency point #2 after the same-frequency point is switched.

Fig. 3 is a specific example based on one of the methods shown in fig. 2.

Fig. 3 shows a schematic diagram of a change in the same frequency point of a terminal device caused by a handover of an active BWP of the terminal device.

As shown in fig. 3, the frequency point corresponding to the source activation BWP of the terminal device is ssb_freq_1, i.e., freq_1 is the original same frequency point of the terminal device, and freq_2 is the original different frequency point of the terminal device. The freq_1 same-frequency point cell service information service cell is an S cell, and neighbor cell information included in a neighbor cell (called neighbor cell in the present application) information list includes neighbor cell 1: n1_1, neighbor 1: n1_2, and so on. The freq_2 different frequency point cell service information service cell is an S cell, and the neighbor cell information included in the neighbor cell information list comprises a neighbor cell 1: n2_1, neighbor 2: n2_2, etc. The active BWP of the terminal device is switched, resulting in a change of the same frequency point of the terminal device. After the same frequency point is changed, freq_2 becomes the current same frequency point of the terminal equipment, and freq_1 is the current different frequency point of the terminal equipment.

The terminal equipment takes the Freq_1 same-frequency point cell service information serving cell as an S cell, and the neighbor cell information included in the neighbor cell information list comprises neighbor cell 1: n1_1, neighbor 1: and multiplexing the n1_2 and other information into an updated Freq_1 different-frequency point neighbor cell information list, wherein the Freq_1 different-frequency point cell service information serves an S cell, and the different-frequency point neighbor cell information comprises neighbor cell 1: n1_1, neighbor 1: n1_2, and so on. The terminal equipment takes a freq_2 different frequency point cell service information service cell as an S cell, and the neighbor cell information included in the neighbor cell information list comprises a neighbor cell 1: n2_1, neighbor 2: and multiplexing the n2_2 and other information into an updated freq_2 same-frequency point neighbor cell information list, wherein the freq_2 same-frequency point cell service information serves an S cell, and the same-frequency point neighbor cell information comprises neighbor cell 1: n1_1, neighbor 1: n1_2, etc

It should be understood that the neighbor cell of freq_1 and the neighbor cell of freq_2 both satisfy the first condition shown in fig. 2, and refer to the above detailed description in fig. 2, and are not repeated herein.

According to the method shown in fig. 2, in the scenario that the same-frequency point of the terminal device is switched, the terminal device directly multiplexes the different-frequency point neighbor information of the first frequency point into the same-frequency point neighbor information list of the first frequency point, and the terminal device directly multiplexes the same-frequency point neighbor information of the second frequency point into the different-frequency point neighbor information list of the second frequency point. After the same frequency point of the terminal equipment changes, the terminal equipment does not need to search and acquire SSB index, so that the time for searching and acquiring SSB index of the terminal equipment is avoided, the time delay for reporting the measurement result of the terminal equipment is reduced, and the mobile performance of the terminal equipment is improved.

Next, the method shown in fig. 2 described above will be described in detail, specifically in connection with three different scenarios.

It should be noted that these three different scenarios are provided to facilitate a better understanding of the method provided by the embodiments of the present application by those skilled in the art, and do not have any limiting effect on the present application. The method provided by the embodiment of the application can be also applied to other scenes, and in order to avoid redundancy, the application is not limited to the above.

Scene one

Assuming that the terminal device is RedCap UE, the active BWP of RedCap UE is switched, and the co-frequency neighbor cell changes due to the change of the SSB frequency point, which further causes the change of the co-frequency point of RedCap UE.

RedCap UE supports configuring non-cell-defined synchronization signal blocks (NonCellDefiningSSB, NCD-SSB) in the related protocol of 3 Gpp. In a connected state scenario, the network device may configure the UE with multiple BWP (not more than 4). Wherein there is at most only one SSB per BWP, wherein the SSB may be a cell definition synchronization signal block (CellDefiningSSB, CD-SSB) or an NCD-SSB, i.e. there are multiple SSBs within the cell bandwidth. When the SSB in the BWP is activated to be the NCD-SSB, redCap UE uses the SSB to perform functions such as timing synchronization and RRM measurement, and the parameter configuration of the NCD-SSB and the CD-SSB may be configured separately only for the center frequency, the SSB period, and the time domain position offset, and other parameters are the same as the CD-SSB.

The NCD-SSB parameters and the serving cell measurement object (SERVINGCELL MEASUREMENT OBJECTS, servingcellMO) can be further configured by signaling messages for the RedCap UE newly added BWP.

It should be appreciated that in the scenario of configuration ServingCellMO in BWP, RRM measurement uses the frequency point of activating SSB in BWP as the reference frequency point for co-frequency cell measurement. Due to the existence of BWP handover, the reference SSB frequency point of the serving cell changes after the BWP is activated, resulting in a change in definition of the co-channel neighbor cell. Since the center frequency point of the SSB of the same frequency is changed, the timing position of the target SSB after BWP handover can be determined for the serving cell due to the timing offset configuration parameters of the NCD-SSB and the CD-SSB. However, for the neighboring cell, after the new same-frequency point and the original same-frequency point are measured, the neighboring cell measurement of the terminal equipment needs to be searched again for measurement and SSB index acquisition, i.e. a certain time delay exists, which leads to the problem of poor mobility of the terminal equipment.

In the scenario that the active BWP of RedCap UE is switched, as an example, all BWP such as RedCap UE are configured with corresponding SSB measurement MO, which may include the following steps:

step 1: for all BWPs RedCap UE, corresponding SSB measurement MOs are configured, the frequency bin is denoted as f_i, and i is the corresponding MO. Wherein, the maximum value of the number of BWP is 4, and the maximum value of i is 4;

Step 2: redCap UE performs measurement on f_i to obtain cell measurement information of f_i frequency points.

The cell measurement information may include one or more of the following: timing information, measurement values, SSB index, etc., and AGC shift information.

Step 3: redCap UE is the j-th BWP, the frequency point is denoted as f_j, that is, the same frequency point corresponding to RedCap UE is denoted as f_j, and the neighbor cell corresponding to the frequency point f_may be referred to as the same frequency neighbor cell.

Step 4: redCap UE are switched, e.g. the active BWP is switched from the j-th BWP to the k-th BWP. When the activated BWP is switched to the kth, the corresponding frequency point f_k is updated to the same frequency point of RedCap UE, and then the frequency point f_j is updated to the different frequency point of RedCap UE, and RedCap UE further judges whether the cells corresponding to the frequency point f_k and the frequency point f_j meet the first condition (the first condition may also be referred to as a condition of a known neighbor cell).

In one possible implementation manner, when the cells corresponding to the frequency point f_k and the frequency point f_j meet the first condition, step 5A is executed: redCap UE multiplexing the f_k different frequency point neighbor cell information before the BWP switching is activated into a neighbor cell list of the current f_k same frequency point; redCap UE multiplexes the neighbor information of the f_j same frequency point before the BWP is activated to the neighbor list of the current f_j different frequency point.

In another possible implementation manner, when the cells corresponding to the frequency point f_k and the frequency point f_j do not meet the first condition, step 5B is executed: redCap UE re-performs cell search and SSB index acquisition and measurement result update on the f_k same-frequency point and the f_j different-frequency point.

It should be understood that the detailed process in this step 5B may be referred to in the prior art, and will not be described herein.

According to the description of the steps 1 to 5, when the BWP is activated to switch, the frequency point corresponding to the BWP is updated from the different frequency point to the same frequency point or from the same frequency point to the different frequency point with respect to RedCap UE. RedCap UE multiplexes (or called inheritance) the neighbor cell measurement results of the frequency points, and does not need to acquire cell measurement information again, so that the time of searching and acquiring SSB index is avoided, and the reporting of the whole measurement result is quickened.

In the scenario that the active BWP of RedCap UE is switched, as an example, the portion BWP of RedCap UE is configured with the corresponding SSB measurement MO, which may include the following steps:

Step 1 configures a corresponding SSB measurement MO for a portion BWP of RedCap UE, where the frequency bin is denoted as f_i, and i is the corresponding MO. Wherein, the maximum value of the number of BWP is 4, and the maximum value of i is 4;

The cell measurement information may include one or more of the following: timing information, measurement values, SSB index, AGC shift information, etc.

Step 3: redCap UE is the j-th BWP, the corresponding frequency point is denoted as f_j, that is, the same frequency point corresponding to RedCap UE is denoted as f_j, and the neighbor cell corresponding to the frequency point f_j may be referred to as a same frequency neighbor cell.

Step 4: redCap UE is switched, e.g. there is a j-th BWP switch to a k-th BWP.

In one possible implementation manner, when the activated BWP is switched to the kth, and the corresponding kth BWP is configured with the corresponding SSB measurement MO, then the frequency point f_k corresponding to the kth BWP is updated to the same frequency point of RedCap UE, then the frequency point f_j is updated to the different frequency point of RedCap UE, and RedCap UE further determines whether the cells corresponding to the frequency point f_k and the frequency point f_j satisfy the first condition (or referred to as a condition of a known neighbor cell). The specific steps are similar to step 4 in the case where all BWPs of RedCap UE are configured with corresponding SSB measurement MOs as described above, and are not described here again.

In another possible implementation, when the active BWP is switched to the kth, and the corresponding kth BWP is not configured with the corresponding SSB measurement MO, then RedCap UE needs to re-perform the neighbor search and SSB index acquisition. According to the relevant protocol, redCap UE updates the CD-SSB frequency point to the same frequency point of RedCap UE and f_j to the different frequency point of RedCap UE. RedCap UE further determines whether the cell corresponding to the CD-SSB frequency point and the frequency point f_j meets a first condition (or a condition called a known neighbor cell).

In one possible implementation manner, when the cell corresponding to the frequency point CD-SSB and the frequency point f_j meets the first condition, step 5A is executed: redCap UE multiplexing the adjacent cell information of the CD-SSB different frequency point before the BWP is activated to the adjacent cell list of the current CD-SSB same frequency point; redCap UE multiplexes the neighbor information of the f_j same frequency point before the BWP is activated to the neighbor list of the current f_j different frequency point.

In another possible implementation manner, when the cell corresponding to the frequency point CD-SSB and the frequency point f_j does not meet the first condition, step 5B is executed: redCap UE carrying out cell search and SSB index acquisition and measurement result update again on the same frequency point of the CD-SSB and the different frequency point of the f_j.

It should be understood that the detailed process in this step 5B is referred to the prior art, and will not be described herein.

According to the description of the above steps 1 to 5, when the activated BWP is switched, and the switched activated BWP is not configured with the corresponding SSB measurement MO, redCap UE updates the related protocol to determine to update the CD-SSB frequency point to RedCap UE same frequency point, and update the f_j same frequency point to RedCap UE different frequency point. RedCap UE multiplexes (or inherits) the neighbor measurement results of the frequency point, the terminal equipment does not need to search again and acquire the SSB index, and reporting of the measurement results of the terminal equipment is quickened.

Scene two

If the terminal equipment is Normal UE, the source serving cell of the terminal equipment is switched to the target serving cell due to the movement of the terminal equipment, and the same frequency point of the terminal equipment is switched. That is, the same frequency point of the source serving cell of the terminal equipment may become a different frequency point of the target serving cell after the terminal equipment is switched.

As an example, for example, cell #0 is a source serving cell of the terminal device, and cell #1 is a target serving cell after handover of the terminal device.

Before the cell is switched, a frequency point (for example, frequency point # 0) in the cell #0 is the same frequency point of the terminal equipment, and a frequency point (frequency point # 1) in the cell #1 is a different frequency point of the terminal equipment. The position of the terminal equipment moves, so that the service cell of the terminal equipment is switched, and the same frequency point of the terminal equipment is further caused to change.

After the cell switching, the frequency point #0 in the cell #0 is updated to be the different frequency point of the terminal equipment, and the frequency point #1 in the cell #1 is updated to be the same frequency point of the terminal equipment.

And the terminal equipment measures the frequency points configured by the source service cell and the frequency points configured by the target service cell and judges whether the first condition is met or not.

It should be appreciated that the first condition includes:

1) In a duration period (for example, a first period) before the cell switching occurrence time of the terminal equipment, the neighbor cell of the source serving cell configuration frequency point and the neighbor cell of the target serving cell configuration frequency point finish measurement reporting, or the terminal equipment has finished identifying the neighbor cell of the source serving cell configuration frequency point and the neighbor cell of the target serving cell configuration frequency point;

2) Before and after cell switching, signal intensities of a neighboring cell of a source serving cell configuration frequency point and a neighboring cell of a target serving cell configuration frequency point are kept above a level which can be identified by terminal equipment, namely, the signal intensities of the neighboring cells relative to the terminal equipment are all greater than or equal to a certain threshold (for example, a first threshold);

3) The measurement configuration parameters of the same frequency point are the same before and after the cell switching.

Wherein measuring configuration parameters may include one or more of: frequency point information, cell identification information, and synchronization signal block SSB information.

It should be understood that, due to the movement of the terminal device, the serving cell of the terminal device is switched, resulting in a change of the same frequency point of the terminal device, the terminal device multiplexes the neighbor information of the source same frequency point directly to the changed neighbor information of the different frequency point, the terminal device multiplexes the neighbor information of the source different frequency point directly to the changed neighbor information of the same frequency point for direct use, and the neighbor information of the source same frequency point and the neighbor information of the source different frequency point both need to satisfy 1), 2) and 3) in the first condition before and after the cell switching.

In one possible implementation manner, when the terminal equipment determines that all neighboring cells of a frequency point configured by a source service cell and all neighboring cells of a frequency point configured by a target service cell meet a first condition, multiplexing all neighboring cell information of a different frequency point of the source service cell before switching into a same frequency point neighboring cell information list of the target service cell after switching; the first terminal equipment multiplexes all neighbor cell information of the same frequency point of the source service cell before switching into a different frequency neighbor cell information list of the target service cell after switching.

In another possible implementation manner, when the terminal equipment determines that a part of adjacent cells of a frequency point configured by the source service cell and a part of adjacent cells of a frequency point configured by the target service cell meet a first condition, and when the part of adjacent cells do not meet the first condition, adjacent cell information of a different frequency point of the source service cell before switching of the first terminal equipment meets the first condition is multiplexed into a same-frequency point adjacent cell information list of the target service cell after switching; the first terminal equipment multiplexes the adjacent cell information of which the same frequency point of the source service cell before switching meets a first condition into a different frequency adjacent cell information list of the target service cell after switching.

It should be understood that, when the terminal device determines that the neighboring cell of the frequency point configured by the source serving cell and the neighboring cell of the frequency point configured by the target serving cell do not meet the first condition, the terminal device needs to perform cell search and SSB index acquisition and measurement result update again on the same frequency point and different frequency points after cell switching. The detailed process may be referred to in the prior art, and will not be described here.

It should also be understood that in the context of cell handover, the same frequency point, different frequency point or different system frequency point of the source serving cell of the terminal device may become the same frequency point, different frequency point or different system frequency point of the target serving cell after cell handover of the terminal device. In this case, the method is also applicable to the measurement method provided by the embodiment of the present application, that is, the terminal device may multiplex the neighbor information of the frequency point before the switching into the neighbor list of the frequency point after the switching. The terminal equipment can multiplex the adjacent cell information of the related frequency points, so that the time of re-searching and acquiring SSB index by the terminal equipment is avoided, and the measurement time delay is reduced.

According to the description of the specific example of the second scenario, the serving cell of the terminal device is switched, so that the same frequency point of the terminal device is correspondingly changed. The terminal equipment can multiplex the adjacent cell information of the same frequency point before switching into the adjacent cell information of the different frequency point after switching, and multiplex the adjacent cell information of the different frequency point before switching into the adjacent cell information of the same frequency point after switching, thereby avoiding the time of searching and acquiring SSB index of the terminal equipment and further improving the switching performance of the terminal equipment.

Fig. 4 is a schematic flow chart of another measurement method according to an embodiment of the present application. As shown in fig. 4, the method includes:

s401, the terminal equipment adds the frequency point #1 as the same frequency point of the terminal equipment, wherein the same frequency point comprises the frequency point #2.

Specifically, before the terminal device adds the frequency point #1 as the same frequency point, the same frequency point of the terminal device is the frequency point #2, the frequency point #1 is a different frequency point of the terminal device, and the terminal device adds the frequency point #1 as the same frequency point of the terminal device, that is, after the same frequency point is added, the same frequency point of the terminal device includes the frequency point #1 and the frequency point #2.

As an example, the terminal device generates a carrier aggregation CA adding carrier element CC frequency point, and a certain different frequency point (for example, frequency point # 1) of the Pcell/PScell cell becomes the same frequency point (service frequency point) of the target cell, that is, the terminal device adds the source different frequency point #1 to become the same frequency point.

S402, the terminal equipment multiplexes the first information into the same-frequency neighbor information list of the frequency point # 1.

Specifically, after the terminal device determines that the frequency point #1 is added to the same frequency point of the terminal device, the terminal device multiplexes the first information into the same frequency neighbor information list of the frequency point # 1. The first information is inter-frequency neighbor information of the frequency point # 1.

It should be understood that, before the terminal device adds the same frequency point, the frequency point #1 is an inter-frequency point of the terminal device, and the neighbor information of the frequency point #1 may be referred to as inter-frequency neighbor information of the frequency point # 1. When the frequency point #1 is the same frequency point of the terminal device, the terminal device may multiplex the different frequency neighbor information of the frequency point #1 into the same frequency neighbor information of the frequency point # 1.

In one possible implementation, the neighboring cells of the frequency point #1 include a first cell that satisfies a first condition, where the first condition includes:

1) In a first time period, the terminal equipment completes cell measurement reporting to the first cell or completes cell identification to the first cell;

2) The signal strength of the first cell relative to the terminal device is greater than or equal to a first threshold.

It should be understood that, in the case that the first cell satisfies the first condition, the terminal device multiplexes first information into the on-channel neighbor cell information list of the frequency point #1, where the first information includes measurement information of the first cell, where the measurement information includes one or more of timing information, measurement value, synchronization signal block index SSB index, AGC shift information, and the like. The first cell may be one or more neighboring cells of the frequency point #1, which is not limited to the present application.

It should also be understood that the magnitude of the first threshold may be determined by the terminal device itself, or predefined by the system or determined by some indication information, which is not particularly limited to this application.

It should also be understood that the first period of time may be some continuous period of time before the terminal device adds the frequency bin #1 as the same frequency bin of the terminal device.

As an example, assume that the neighbor cell corresponding to the frequency point #1 is the cell #1. Under the condition that the frequency point #1 is updated from the different frequency point of the terminal equipment to the same frequency point of the terminal equipment, in a certain continuous time period before the frequency point #1 is updated from the different frequency point of the terminal equipment to the same frequency point of the terminal equipment, the terminal equipment completes cell measurement reporting on the cell #1 or completes cell identification on the cell #1, and the signal intensity of the cell #1 relative to the terminal equipment is larger than or equal to a certain threshold (for example, a first threshold) before and after the frequency point #1 is updated from the different frequency point of the terminal equipment to the same frequency point of the terminal equipment, namely the cell #1 meets a first condition, and the cell #1 is a known neighbor cell of the terminal equipment. Under the condition that the frequency point #1 is updated from the different frequency point of the terminal equipment to the same frequency point of the terminal equipment, the terminal equipment can directly multiplex the information of the cell #1 into the same frequency neighbor cell information list of the same frequency point including the frequency point #1 of the terminal equipment.

According to the method shown in fig. 4, in the scenario of adding the same frequency point of the terminal device (for example, adding the service frequency point under CA), the terminal device directly multiplexes the different frequency point neighbor information of the frequency point #1 into the same frequency point neighbor information list of the frequency point #1, and the terminal device does not need to search and acquire the SSB index for the neighbor of the frequency point #1, so that the time for searching and acquiring the SSB index of the terminal device is avoided, the time delay for reporting the measurement result of the terminal device is reduced, and the mobility performance of the terminal device is improved.
