This application claims priority to the Chinese patent application filed with the China Patent Office on April 19, 2022, with application number 202210409911.4 and the invention name "communication method and device, computer-readable storage medium", the entire content of which is incorporated herein by reference. Applying.

Technical field

The present application relates to the field of communication technology, and specifically to a communication method and device, and a computer-readable storage medium.

Background technique

With the continuous deployment and widespread application of the fifth-generation mobile communications technology (The Fifth-Generation mobile communications, referred to as 5G) systems, in order to better meet the requirements of mid-range IoT applications such as industrial wireless sensors, video surveillance and wearable devices, equipment Specific needs such as reduced complexity and cost, reduced size, lower energy consumption, etc. In the protocol Rel-17 version, the 3rd Generation Partnership Project (3GPP for short) defines New Radio (NR for short, also known as New Wireless) low-complexity and low-cost equipment. That is, the User Equipment (UE) with reduced capabilities (RedCap for short) can be referred to as a low-capability terminal, or as a simplified version of NR (NR-lite).

For R15/16 non-RedCap UEs that can support 100MHz bandwidth in the FR1 frequency band (corresponding to the frequency range 450 MHz (MHz) to 6000MHz), the base station can configure part of the bandwidth of the non-low-capability terminal (Bandwidth part, referred to as BWP) includes cell-defined synchronization signal block (Cell Defining-Synchronization Signal Block, referred to as CD-SSB). However, for low-capability terminals that only support 20MHz, if the BWPs of all low-capability terminals include CD-SSB, it may cause all low-capability terminals to be concentrated in frequency domain resources near CD-SSB, causing congestion.

If low-capability terminals can go outside the BWP to perform measurements through the measurement gap, Then the base station can flexibly configure low-capability terminals in positions within the carrier. However, this may cause low-capability terminals to require frequent retuning (retuning) for measurement, resulting in an increase in power consumption.

Therefore, in the latest research, a non-cell defined synchronization signal block (NCD-SSB) is introduced for connected low-capability terminals to perform cell measurements. NCD-SSB can also be called low-capability terminal dedicated SSB, or can be called second synchronization signal block (second Synchronization Signal/Physical Broadcast Channel Block, referred to as second SS/PBCH block).

However, existing non-connected low-capability terminals still need to monitor paging in the initial BWP (initial BWP) associated with CD-SSB, and perform cell measurement, selection or reselection based on CD-SSB. Even a low-capacity terminal in a connected state may not be able to correctly measure the NCD-SSB of neighboring cells due to incorrect neighboring cell information configured by the base station. Both of the above situations may cause the low-capability terminal to reselect or switch to an inappropriate cell. If it cannot reselect or switch to a cell configured with a suitable low-capability terminal dedicated SSB, this will cause access failure and increase access time. extension.

Detailed ways

The method provided by the embodiment of the present application involves a base station and a terminal, and uplink and downlink signals can be transmitted between the base station and the terminal.

The terminal (terminal) in the embodiment of this application is a device with wireless communication functions, which can be called user equipment (User Equipment, UE for short), terminal equipment, mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), access terminal equipment, vehicle-mounted terminal equipment, industrial control terminal equipment, UE unit, UE station, mobile station, remote station, remote terminal equipment, mobile equipment, UE terminal equipment, wireless communication equipment, UE agent or UE device, etc. . Terminals can be fixed or mobile. It should be noted that the terminal can support at least one wireless communication technology, such as Long Term Evolution (LTE), new radio (NR), etc. For example, the terminal can be a mobile phone (mobile phone), tablet computer (pad), desktop computer, laptop computer, all-in-one computer, vehicle-mounted terminal, virtual reality (VR) terminal device, augmented reality (AR) terminal device , wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, transportation safety ( Wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local Wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, wearable device, future mobile communication network or terminal equipment in the future evolved public land mobile network (PLMN), etc. In some embodiments of the present application, the terminal may also be a device with transceiver functions, such as a chip system. Among them, the chip system may include chips and may also include other discrete devices.

The terminal in the embodiment of this application specifically refers to a low-capability terminal. Specifically, the NR R15/16 version of the terminal can support a terminal maximum channel bandwidth of 100MHz in the FR1 frequency band. In order to reduce the complexity and cost of the terminal, the low-capacity terminal introduced in R17 reduces the maximum channel bandwidth, such as reducing it to 20MHz and 100MHz for the FR1 and FR2 frequency bands respectively. On the other hand, the BWP of a low-capability terminal cannot be larger than the maximum channel bandwidth of the low-capability terminal.

In the embodiment of this application, the network device is a device that provides wireless communication functions for terminals, and may also be called access network equipment, radio access network (RAN) equipment, or access network elements. Among them, the network device can support at least one wireless communication technology, such as LTE, NR, etc. Examples of network equipment include but are not limited to: next generation base station (generation nodeB, gNB), evolved node B (evolved node B, eNB), wireless network control in the fifth generation mobile communication system (5th-generation, 5G) Radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved node B, Or home node B, HNB), baseband unit (baseband unit, BBU), transceiving point (transmitting and receiving point, TRP), transmitting point (transmitting point, TP), mobile switching center, etc. The network device can also be a wireless controller, centralized unit (CU), and/or distributed unit (DU) in a cloud radio access network (CRAN) scenario, or an access network The equipment can be relay stations, access points, vehicle-mounted equipment, terminal equipment, wearable devices, network equipment in future mobile communications or network equipment in future evolved PLMN, etc. In some embodiments, the network device may also be a device with a wireless communication function for the UE, such as a chip system. For example, the chip system may include a chip, and may also include other discrete devices.

The embodiment of this application takes a base station as an example to specifically describe the implementation method on the network side.

As mentioned in the background technology, for low-capacity terminals in the existing technology, whether in the connected state or the non-connected state, they may reselect or switch to an inappropriate cell, causing access failure and increasing access delay. .

Specifically, in the existing technology, a low-capability terminal in a connected state can measure neighboring cells based on NCD-SSB (that is, low-capability terminal dedicated SSB). To this end, the base station needs to configure a dedicated SSB for low-capability terminals in the adjacent area for low-capability terminals to conduct testing. quantity. However, in the prior art, the cell exchange information between base stations only indicates the configuration of the CD-SSB, and does not exchange the configuration information of the low-capability terminal-dedicated SSB, resulting in the base station being unable to inform the low-capacity terminal of the neighboring cell's low-capacity terminal-dedicated SSB. specific configuration. This may cause the base station to make errors when configuring neighbor cell information for connected low-capability terminals, causing the low-capability terminal to be handed over to an inappropriate target cell, causing handover failure.

On the other hand, the new protocol version will introduce low-capability terminals that support the non-connected state. They can configure the low-capacity terminal-specific SSB in the low-capacity dedicated BWP (Redcap specific BWP) for non-connected state measurement and cell selection/reselection. At the same time, you can also configure dedicated SSB for low-capability terminals in neighboring cells for measurement. However, as mentioned above, when currently configuring neighbor cell information, the base station cannot know which set of SSBs has been specifically configured as a low-capability terminal-specific SSB in the neighbor cell, and therefore cannot configure the correct adjacent low-capability terminal-specific SSB in the system message. . For example, the base station cannot correctly configure the frequency and period of the dedicated SSB for low-capability terminals of adjacent base stations. This will cause low-capability terminals in non-connected states to be unable to correctly measure neighboring cell signals, resulting in longer measurement time and inaccurate measurement results. When the above problems occur, it will also cause low-capability terminals to reselect to inappropriate cells, which will cause failures during access and increase the access delay.

The base station adopting the solution of the present application carries the configuration information of the low-capability terminal-specific SSB through system messages, and/or instructs the low-capability terminal to use the low-capability terminal-specific SSB in the non-connected state. Correspondingly, the non-connected low-capability terminal based on the solution of the present application receives the system message, and uses the low-capability terminal dedicated SSB to perform cell measurement according to the instructions of the system message. This implementation plan ensures that low-capability terminals in a non-connected state can accurately learn the dedicated SSB for low-capability terminals configured on the network side. Furthermore, according to the indicated low-capability terminal-specific SSB, the low-capability terminal can quickly reselect or switch to a cell configured with a low-capability terminal-specific SSB, thereby preventing the low-capability terminal from mistakenly reselecting a cell that is not configured with a low-capability terminal SSB. resulting in access failure. Furthermore, since reselection of low-capability terminals to inappropriate cells is effectively avoided, the access delay of low-capability terminals is also reduced. It should be noted that the SSB dedicated to low-capability terminals in this application may also be called a non-cell-defining synchronization signal block (NonCelldefiningSSB), or the SSB configured and used by low-capability terminals.

In order to make the above purposes, features and beneficial effects of the present application more obvious and understandable, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Figure 1 is a signaling interaction diagram of a communication method provided by an embodiment of the present application.

This implementation can be applied to cell reselection or handover scenarios for low-capability terminals. In this scenario, the base station instructs the low-capability terminal the configuration information of the low-capability terminal's dedicated SSB, and/or the base station instructs the low-capability terminal to use the low-capability terminal SSB in a specific state. Correspondingly, the low-capability terminal uses the low-capability terminal-dedicated SSB for cell measurement according to the instructions of the base station, and attempts to access the cell configured with the low-capability terminal-dedicated SSB when the measurement results meet the requirements. Among them, the measurement results meeting the requirements can mean that the measurement results meet the S criterion and the R criterion. In the scenario shown in FIG. 1 , the specific state may be, for example, a non-connected state, and the non-connected state may be an idle state, or may be an inactive state.

In a specific implementation, in the communication method provided by the following steps (abbreviated as S) 101 to S103, the actions performed by the low-capacity terminal can be performed by a chip with communication functions in the low-capacity terminal, or can be performed by a chip in the low-capacity terminal. The baseband chip executes. The actions performed by the base station can be performed by a chip with communication functions in the base station, or by a baseband chip in the base station.

Specifically, referring to Figure 1, the communication method described in this embodiment may include the following steps:

S101. The base station sends a system message to the low-capability terminal. The system message includes first indication information and/or period information of the low-capability terminal dedicated synchronization signal block SSB. The first indication information is used to indicate that the low-capability terminal is not connected. state uses the dedicated SSB for low-capability terminals. Correspondingly, the low-capability terminal receives system messages from the base station.

The dedicated SSB for low-capability terminals may be the SSB configured by the base station for low-capability terminals to perform cell measurements, and may be the SSB of the current cell or the SSB of neighboring cells. SSB dedicated to low-capability terminals It may also be called NCD-SSB, or may be called second synchronization signal block (second SS/PBCH block).

In a specific implementation, in S101, the base station can broadcast a system message, and low-capability terminals within the signal coverage of the base station receive the system message.

In a specific implementation, the system message may include period information of the low-capability terminal dedicated SSB, and the first indication information may be omitted in this specific implementation.

Specifically, the periodic information of the low-capability terminal-dedicated SSB can be carried in one or more system information blocks (System Information Block, SIB for short) of the system message, such as one or more of SIB2, SIB4 and SIB1.

Furthermore, the system message may also include the frequency information of the SSB dedicated to low-capability terminals, and the information element (Information Element, IE for short) carrying the frequency information may be called the SSB absolute frequency (absoluteFrequencySSB).

When the low-capability terminal SSB is configured by the neighboring cell of the low-capability terminal's serving cell, and the center frequency of the serving cell and the neighboring cell is the same, but the frequency is different from the frequency of the low-capability terminal SSB, the neighboring cell can be used as The co-frequency cell of the serving cell configures a system message to indicate the low-capability terminal dedicated SSB to the low-capability terminal. The serving cell and neighboring cells may be managed by different base stations, and the base station that manages the serving cell executes S101 to send a system message. For example, the neighboring cell co-frequency measurement information of SIB2 can add the period information and frequency information of the dedicated SSB for low-capability terminals in the neighboring cell. For another example, the neighboring cell inter-frequency measurement information of SIB4 can add the period information of the low-capability terminal-dedicated SSB. For another example, the neighboring cell intra-frequency measurement information of SIB2 can add the period information and frequency information of the low-capability terminal-dedicated SSB, and the neighboring cell inter-frequency measurement information of SIB4 can add the period information of the low-capability terminal-dedicated SSB.

Or, when the low-capability terminal SSB is configured by a neighboring cell of the low-capability terminal's serving cell, the center frequency of the serving cell and the neighboring cell is the same, but the frequency is different from the frequency of the low-capability terminal SSB. System messages may also be configured for inter-frequency cells using neighboring cells as serving cells to indicate low-capability terminals dedicated SSBs to low-capability terminals. For example, SIB2 The periodic information of low-capability terminal dedicated SSB can be added to the co-frequency measurement information of neighboring cells. For another example, the neighboring cell inter-frequency measurement information of SIB4 can add the period information of the low-capability terminal-dedicated SSB. For another example, the neighboring cell intra-frequency measurement information of SIB2 and the neighboring cell inter-frequency measurement information of SIB4 can respectively add the period information of the low-capability terminal-dedicated SSB.

In one example, the period information of the low-capability terminal-dedicated SSB can be carried in the serving cell common configuration (servingCellConfigCommon) of SIB1.

In a specific implementation, the system message may only include the first indication information to instruct the low-capability terminal to use the low-capability terminal dedicated SSB to perform measurements on the current cell and/or neighboring cells in the non-connected state. In this specific implementation, the dedicated SSB for low-capability terminals may be pre-configured, or may be indicated to the low-capability terminal through other signaling or interactive methods.

For example, a new IE may be added to the system message. The new IE may be called an initial downlink BWP (initialDownlinkBWP-RedCap) for low-capability terminals, and the IE carries first indication information. Furthermore, in this specific implementation, it can also be clarified in the IE description that if it is a low-capability terminal that supports non-connected state NCD-SSB, this IE will always be used.

Further, the first indication information may be carried in any one of System Information Block 2 (SIB2 for short), SIB4 and SIB1.

In a specific implementation, the system message may simultaneously carry the first indication information and the period information of the low-capability terminal dedicated SSB.

In a specific implementation, the system message may include second indication information for instructing the low-capability terminal's serving cell to configure a dedicated SSB for the low-capability terminal based on the SSB of this cell. For example, the system message includes period information of the low-capability terminal dedicated SSB and second indication information, where the second indication information indicates that the low-capability terminal dedicated SSB is the local SSB configured for the serving cell. The number of dedicated SSBs for low-capability terminals may be one or more, and the system message includes period information of each SSB dedicated for low-capability terminals.

In a specific implementation, the system message may include third indication information, used to instruct the serving cell to configure a dedicated SSB for low-capability terminals based on the SSB of the neighboring cell. For example, system The message includes period information of the low-capability terminal-dedicated SSB and third indication information, where the third indication information indicates that the low-capability terminal-dedicated SSB is a neighboring cell SSB. The number of dedicated SSBs for low-capability terminals may be one or more, and the system message includes period information of each SSB dedicated for low-capability terminals.

In a specific implementation, the system message may include both the second indication information and the third indication information. For example, the system message includes period information of multiple low-capability terminal dedicated SSBs, second indication information and third indication information, wherein the second indication information indicates that some of the multiple low-capability terminal dedicated SSBs are local SSBs configured by the serving cell. , the third indication information indicates that the remaining portions of the multiple low-capability terminal dedicated SSBs are neighboring cell SSBs.

In a specific implementation, continuing to refer to Figure 1, the communication method described in this embodiment may further include the steps:

S102: The low-capability terminal performs cell measurement based on the low-capability terminal dedicated SSB.

For example, the system message includes the first indication information. Correspondingly, when performing S102, the low-capability terminal uses the preconfigured low-capability terminal dedicated SSB to perform cell measurement according to the instruction of the first indication information.

For another example, the system message includes period information of the low-capability terminal's dedicated SSB. Correspondingly, the low-capability terminal performs cell measurements based on the low-capability terminal SSB configured in the system message.

For another example, the system message includes the first indication information and the period information of the low-capability terminal dedicated SSB. Correspondingly, when performing S102, the capable terminal uses the low-capability terminal dedicated SSB configured in the system message to perform cell measurement according to the instructions of the first indication information. .

In a specific implementation, before S101, the base station may also perform the step of obtaining a low-capability terminal dedicated SSB.

For example, the base station may obtain the low-capability terminal-specific SSB based on the preconfiguration, and then add the obtained configuration information (such as period information) of the low-capability terminal-specific SSB to the system message and send it. The preconfigured dedicated SSB for low-capability terminals can be the base station's own configuration or the configuration of a neighboring base station.

For another example, the base station can obtain the low-capability terminal-specific SSB configured by the neighboring base station through interaction with other base stations (such as neighboring base stations).

In a specific implementation, continuing to refer to Figure 1, before S101, the base station may perform S103 to receive a first message sent by a neighboring base station. The first message is used to indicate one or more SSBs configured by the neighboring base station. The first message includes Information used to determine one or more low-capability terminal-specific SSBs. The low-capability terminal-specific SSB is an SSB configured for use by low-capability terminals among the one or more SSBs.

The first message exchanged between base stations may not include CD-SSB. In this case, an SSB indicated by the neighboring base station through the first message is the low-capability terminal-specific SSB configured by the neighboring base station.

When multiple SSBs are configured in the first message, the neighboring base station may further indicate in the first message that one or more of the multiple SSBs are dedicated SSBs for low-capability terminals.

The first message may be, for example, a measurement timing configuration (MeasurementTimingConfiguration) information element. The measurement timing configuration information element can be transmitted during the Xn interface setup/configuration update (Setup/Configuration Update) interaction, and can be carried in the NR serving cell information (Served Cell Information NR) and/or NR neighbor cell information (Neighbor Information NR) middle.

In a specific implementation, the first message may include a first field and one or more second fields. One or more second fields may correspond to one or more SSBs one-to-one, and one second field includes information indicating the corresponding SSB. For example, each second field carries configuration parameters corresponding to the SSB. The second field may be, for example, a measuring timing IE.

The first field may be used to indicate a low-capability terminal-specific SSB among one or more SSBs. For example, the first field may be added to the measurement timing configuration IE of the measurement timing configuration message.

In one example, the first message may include n second fields, and the specific content of the first field may be, for example, that the SSB corresponding to the i-th second field in the measurement timing IE is a low-capability terminal dedicated SSB. Among them, 1≤i≤n, n is a positive integer greater than or equal to 1. For example, The first field may indicate that the second second field in the measurement sequence IE is a low-capability terminal-specific SSB. In addition, the first second field in the measurement sequence IE is CD-SSB.

In a specific implementation, the first message may include one or more second fields, wherein one or more second fields may correspond to one or more SSBs, and the second field corresponding to the non-low-capability terminal-specific SSB Information indicating the corresponding SSB may be included, and the second field corresponding to the low-capability terminal-dedicated SSB may include configuration parameters of the low-capability terminal-dedicated SSB.

For example, the measurement timing IE in the first message may be the second field corresponding to the non-low-capability terminal-dedicated SSB, where each second field carries configuration parameters of the corresponding SSB. Furthermore, a low-capability terminal-specific SSB measurement timing IE or a low-capability terminal-specific SSB measurement timing list IE may be added to the first message, and the IE includes one or more second fields corresponding to the low-capability terminal-specific SSB.

In a specific implementation, the first message may include one or more second fields, where one or more second fields correspond to one or more SSBs one-to-one, and the second field corresponding to the low-capability terminal dedicated SSB may include Information used to indicate the corresponding SSB, and information used to indicate that the SSB corresponding to the second field is a dedicated SSB for low-capability terminals.

For example, the second field corresponding to the low-capability terminal-dedicated SSB includes the configuration parameters of the low-capability terminal-dedicated SSB, and an indication indicating that the SSB is a low-capability terminal-dedicated SSB. .

In a specific implementation, for the situation where the first message indicates multiple low-capability terminal-dedicated SSBs, the first message may further include a third field used to indicate the camping or switching priorities of the multiple low-capability terminal-dedicated SSBs.

In a specific implementation, before/at the same time/after executing S103, further interaction between base stations can be performed on whether to allow half-duplex low-capability terminals to access the cell (Half-Duplex FDD RedCap), where FDD is frequency division duplex ( Frequency Division Duplexing, short for FDD). For example, it may be indicated that the third bit is half-duplex in the information element of the low-capability terminal broadcast information (RedCap Broadcast Information), that is, the third bit =Half-Duplex FDD, indicating that the third bit is used to indicate whether the cell allows half-duplex low-capability terminals to access the cell.

From the above, the base station using the solution of the present application carries the configuration information of the low-capability terminal-dedicated SSB through system messages, and/or instructs the low-capability terminal to use the low-capacity terminal-dedicated SSB in the non-connected state. Correspondingly, the non-connected low-capability terminal based on the solution of the present application receives the system message, and uses the low-capability terminal dedicated SSB to perform cell measurement according to the instructions of the system message. This implementation plan ensures that low-capability terminals in a non-connected state can accurately learn the dedicated SSB for low-capability terminals configured on the network side. Furthermore, according to the indicated low-capability terminal-specific SSB, the low-capability terminal can quickly reselect or switch to a cell configured with a low-capability terminal-specific SSB, thereby preventing the low-capability terminal from mistakenly reselecting a cell that is not configured with a low-capability terminal SSB. resulting in access failure. Furthermore, since reselection of low-capability terminals to inappropriate cells is effectively avoided, the access delay of low-capability terminals is also reduced.

This implementation can be applied to scenarios where base stations exchange dedicated SSB configuration information for low-capability terminals. In this scenario, the neighboring base station indicates the low-capability terminal-specific SSB configured by the neighboring base station to the base station, so that the base station can accurately indicate the low-capability terminal-specific SSB of the neighboring base station to the low-capability terminal when configuring the neighboring cell information.

In a specific implementation, the communication method provided in S301 below may be executed by a chip with a communication function in a neighboring base station, or may be executed by a baseband chip in a neighboring base station.

Specifically, referring to Figure 2, the communication method described in this embodiment may include the following steps:

S201. The neighboring base station sends a first message to the base station. The first message is used to indicate one or more SSBs configured by the neighboring base station. The first message includes information used to determine one or more SSBs dedicated to low-capability terminals. The first message is dedicated to low-capability terminals. An SSB is an SSB configured for use by low-capability terminals among one or more SSBs. Correspondingly, the base station receives the first message from the neighboring base station.

Those skilled in the art understand that S201 can be regarded as an execution step corresponding to S103 in the embodiment shown in FIG. 1, and the two complement each other in terms of specific implementation principles and logic. Therefore, the explanation of nouns involved in this embodiment can refer to the embodiment shown in Figure 1 The relevant description will not be repeated here.

Further, the base station may continue to execute S101 in the embodiment shown in FIG. 1 to indicate the configuration information of the low-capability terminal-dedicated SSB configured by the neighboring base station to the low-capability terminal through a system message.

From the above, the low-capability terminal-specific SSB configured by the base stations using the solution of the present application is exchanged through the first message, so that the current base station can accurately learn the low-capability terminal-specific SSB configured by the neighboring base station. Further, the current base station may carry the configuration information of the low-capability terminal-dedicated SSB configured by the neighboring base station in the system message or RRC signaling.

Figure 3 is a signaling interaction diagram of a communication method provided by another embodiment of the present application.

This implementation can be applied to cell reselection or handover scenarios for low-capability terminals. In this scenario, base stations exchange configuration information of low-capability terminal-dedicated SSBs with each other, and indicate to low-capability terminals the low-capability terminal-dedicated SSB configured by neighboring base stations, and/or the base station instructs low-capability terminals to use low-capability terminals in a specific state. Terminal SSB. Correspondingly, the low-capability terminal uses the low-capability terminal-dedicated SSB for cell measurement according to the instructions of the base station, and attempts to access the cell configured with the low-capability terminal-dedicated SSB when the measurement results meet the requirements. Among them, the measurement results meeting the requirements can mean that the measurement results meet the S criterion and the R criterion. In the scenario shown in Figure 3, the specific state may be, for example, a connected state.

In a specific implementation, in the communication method provided in S301 to S303 below, the actions performed by the low-capability terminal can be performed by a chip with communication functions in the low-capability terminal, or by a baseband chip in the low-capacity terminal. The actions performed by the base station/neighboring base station may be performed by a chip with a communication function in the base station/neighboring base station, or by a baseband chip in the base station/neighboring base station.

Specifically, referring to Figure 3, the communication method described in this embodiment may include the following steps:

S301. The neighboring base station sends a first message to the base station. The first message is used to indicate one or more synchronization signal blocks SSB configured by the neighboring base station. The first message includes information used to determine one or more low-capability terminal dedicated SSBs. A dedicated SSB for capable terminals is an SSB configured for use by low-capable terminals among one or more SSBs. Correspondingly, the base station receives the first A message.

Further, continuing to refer to Figure 3, the communication method described in this embodiment may include the following steps:

S302. The base station sends Radio Resource Control (RRC) signaling to the low-capability terminal. The RRC signaling may include fourth indication information and/or period information of the dedicated SSB for the low-capability terminal. The fourth indication information is Used to instruct low-capability terminals to use low-capability terminal dedicated SSB in the connected state. Correspondingly, the low-capability terminal receives RRC signaling from the base station.

Among them, the low-capability terminal-specific SSB in the RRC signaling is configured at least by a neighboring cell of the serving cell to which the low-capability terminal belongs. That is, the base station configures at least the low-capability terminal dedicated SSB received from the neighboring base station in S301 to the low-capability terminal through RRC signaling. Furthermore, the low-capability terminal-specific SSB in the RRC signaling may also include the low-capability terminal-specific SSB configured by the base station itself.

For explanations of nouns involved in S302, please refer to the relevant description of S101 in the embodiment shown in Figure 1, and will not be described again here. The difference between S302 and S101 is that the low-capability terminal as the receiving end in S302 is in the connected state, while the low-capacity terminal as the receiving end in S101 is in the non-connected state. Correspondingly, in S302, RRC signaling is used to carry the fourth indication information and/or the period information of the low-capability terminal-dedicated SSB, while in S101, a system message is used to carry the first indication information and/or the low-capacity terminal-dedicated SSB. cycle information.

In a specific implementation, the RRC signaling may include fourth indication information to instruct the low-capability terminal to use the low-capability terminal dedicated SSB to perform measurements on its own cell and/or neighboring cells in the connected state. For example, a new IE may be added to the RRC signaling, and the new IE carries fourth indication information.

S303: The low-capability terminal performs cell measurement based on the low-capability terminal dedicated SSB.

For explanations of nouns involved in S303, please refer to the relevant description of S102 in the embodiment shown in Figure 1, and will not be described again here.

Therefore, whether it is a low-capacity terminal in the connected state in this embodiment or a low-capacity terminal in the non-connected state in the embodiment shown in Figure 1, it can smoothly and quickly switch or reselect to a low-capacity configuration managed by a neighboring base station. A cell where the terminal is dedicated to SSB. Based on the solution of this application, the probability of low-capability terminals reselecting to inappropriate cells is reduced, and the access delay is also greatly improved.
