Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] With the gradual evolution of communication systems, the spectrum used for wireless communications is getting wider and wider, the number of transmitting antennas in base stations is increasing, and the power consumption is getting higher and higher. At the same time, the frequency band of network deployment during communication increases, and the coverage range becomes smaller, resulting in denser deployment of base stations and higher power consumption of the entire network. For example, the power consumption of a single fifth-generation mobile communication technology (5th generation, 5G) base station is generally 2-3 times that of a typical fourth-generation mobile communication technology (4th generation, 4G) base station. Therefore, "low carbon" has received more and more attention in communication networks, for example, people are paying more and more attention to how to reduce the energy consumption of base stations.

[0003] The base station periodically sends some public information to facilitate the terminal device to identify the network device and access the network. For cells with no service transmission demand or small service transmission demand, the base station still needs to send public information periodically, which results in a large overhead of the base station. At present, the base station can reduce the power consumption of the base station by shutting down some components (such as radio frequency channels, intermediate frequency channels, baseband chips). Among them, the base station may not be able to transmit some public signals during the period when some components are shut down. When the terminal device has access requirements or service transmission requirements, it may not be able to access the network in time.

[0004] Common signals include: synchronization signal block (synchronization signal and PBCH block, SSB) and physical broadcast channel (physical broadcast channel, PBCH) block, system information block 1 (system information block 1, SIB1). SSB can be used for terminal device synchronization and obtaining information related to access cells, and SIB1 is used to evaluate whether the terminal device is allowed to access the cell and define the scheduling of other system messages.

[0005] Therefore, some researchers have proposed that the base station can shut down some components, and when the terminal device has communication needs, it can send a wake-up signal to the base station, requesting the base station to send SIB1 and / or SSB, thereby avoiding the problem of high power consumption caused by the base station periodically sending SIB1 and / or SSB, and achieving base station energy saving.

[0006] However, after the terminal device sends a wake-up signal, even if it receives the public signal of the target cell, it may not be able to access the target cell. For example, the target cell currently does not allow the terminal device to access. In this way, the act of sending a wake-up signal causes a waste of terminal device resources and also causes the base station to send a public signal, but the terminal device cannot access, increasing the power consumption of the base station. Summary of the invention

[0111] For example, the related functions of the first terminal device, the second terminal device, the first network device, and the second network device involved in the present application can be realized by Figure 2 The communication device 200 is used to implement the communication device 200. Figure 2200 is a schematic diagram of the structure of a communication device 200 provided in an embodiment of the present application. The communication device 200 includes one or more processors 201, a communication line 202, and at least one communication interface ( Figure 2 The example in which the communication interface 204 and a processor 201 are included is merely exemplary), and a memory 203 may also be included optionally.

[0116] The memory 203 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 201. The processor 201 is used to execute the computer-executable instructions stored in the memory 203, thereby realizing the communication method provided in the embodiment of the present application.

[0117] Alternatively, optionally, in an embodiment of the present application, the processor 201 may also perform processing-related functions in the communication method provided in the following embodiments of the present application, and the communication interface 204 is responsible for communicating with other devices or communication networks, which is not specifically limited in the embodiments of the present application.

[0118] Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.

[0119] In a specific implementation, as an embodiment, the processor 201 may include one or more CPUs, such as Figure 2 CPU0 and CPU1 in.

[0120] In a specific implementation, as an embodiment, the communication device 200 may include multiple processors, such as Figure 2 The processor 207 and the processor 201 in the embodiment of the present invention are shown in FIG. 1 .

In other embodiments, they may also be other names. The communication method provided in the present application does not make specific limitations on this.

[0126] It is understandable that, in the embodiment of the present application, each network element may perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples, and the embodiment of the present application may also perform other operations or variations of various operations. In addition, each step may be performed in a different order presented in the embodiment of the present application, and it is possible that not all operations in the embodiment of the present application need to be performed.

[0127] Figure 3 It is an example of a communication method provided in an embodiment of the present application. The method is illustrated by taking the interaction between the first terminal device and the first network device as an example. Of course, the subject that executes the action of the first terminal device in the method can also be a device / module in the first terminal device, such as a chip, a processor, a processing unit, etc. in the first terminal device; the subject that executes the action of the first network device in the method can also be a device / module in the first network device, such as a chip, a processor, a processing unit, etc. in the network device, which is not specifically limited in the embodiment of the present application. The processing performed by a single execution subject (for example, a first terminal device or a first network device) in the embodiment of the present application can also be divided into executions by multiple execution subjects, which can be logically and / or physically separated. For example, the processing performed by the first network device can be divided into executions by at least one of CU, DU and RU.

[0128] Some terms involved in this application are explained in detail below.

[0129] (1) Public signal.

[0130] It can be called public information or non-dedicated information, or it can be understood as information sent by one communication device to multiple communication devices. Taking downlink communication as an example, public information can be understood as information sent by a network device to multiple terminal devices or a terminal device group in a cell, or it can be understood as information sent by a network device to a certain terminal device or a certain terminal device group in a cell, or it can be understood as information that can be used by multiple terminal devices or a terminal device group in a cell. For example, public information can be system information, synchronization signals or paging messages, etc.

[0131] The public signal may be used, for example, for processes such as terminal equipment identifying a cell, initial access of the terminal equipment to a cell, neighboring cell measurement, or cell switching.

[0132] (2) The public signal of the first cell.

[0133] It can also be understood as a common signal corresponding to the first cell. The common signal corresponding to the first cell may include a first common signal and / or a second common signal, wherein the first common signal corresponding to the first cell is used for synchronization of the first terminal device and acquisition of relevant information of the first cell; the second common signal corresponding to the first cell is used to evaluate whether the first terminal device is allowed to access the first cell and define the scheduling of other system messages.

[0134] (3) Energy saving of network equipment (base stations).

[0135] Network equipment needs to periodically send some public information so that terminal equipment can identify network equipment and access the network. For cells with no service transmission requirements or small service transmission requirements, network equipment still needs to periodically send public information, which results in a large overhead for network equipment. One possible way to save energy is that network equipment can reduce signal transmission by shutting down some components (such as radio frequency channels, intermediate frequency channels, baseband chips), etc., so as to achieve energy saving of network equipment. However, in this way, if the network equipment cannot transmit some public signals, it cannot access the network when the terminal equipment has transmission requirements. Based on this, one possible way is that the terminal equipment can send a wake-up signal to trigger the network equipment to send the corresponding public signal to facilitate the terminal equipment to obtain access information. However, the terminal equipment sends a wake-up signal to wake up the network equipment to send the target cell public signal. If the terminal equipment determines that the target cell cannot be accessed based on the public signal at this time, it will cause a waste of resources for both the terminal equipment and the network equipment.

[0136] Based on the above analysis, the present application proposes a communication method, which enables the first terminal device to first obtain the configuration information of the first cell by designing a new interaction process, so as to determine and trigger the first network device to send a public signal.

[0137] For example, Figure 3 The method 300 includes:

[0138] S310, the first network device sends configuration information of the first cell to the first terminal device; correspondingly, the first terminal device receives the configuration information of the first cell from the first network device.

[0139] In one possible implementation, the configuration information of the first cell includes first information and second information. In an embodiment of the present application, the first information is used to determine whether the first cell is prohibited; the second information is used to determine whether the first cell is suitable for residence. Alternatively, the first information is used to indicate the parameters of whether the first cell is prohibited; the second information is used to indicate the parameters of whether the first cell is suitable for residence. Alternatively, the first terminal device can determine whether the first cell is prohibited based on the parameters in the first information; the first terminal device can determine whether the first cell is suitable for residence based on the parameters in the second information. In this implementation, the first terminal device can first obtain the first information and the second information, and determine whether to send the first signal based on the first information and the second information.

[0140] In this implementation, the first terminal device determines whether the first cell is prohibited and whether the first cell is suitable for residence based on the first information and the second information. If the first terminal device determines that the first cell is not prohibited and the first cell is suitable for residence, the first terminal device wakes up the first cell, or in other words, the first terminal device requests the transmission of the common signal of the first cell (such as the first common signal and the second common signal, or the second common signal). This can reduce the energy waste of the first network device caused by the first terminal device waking up the first cell that is prohibited and / or not suitable for residence, or reduce the energy waste of the first network device caused by the first terminal device requesting the transmission of the common signal of the first cell that is prohibited and / or not suitable for residence. It can be understood that in this implementation, the first information and the second information are necessary information for implementing the above process. In the embodiment of the present application, the description of the first signal can refer to the following step S320, which will not be repeated here.

[0141] In another possible implementation, the configuration information of the first cell includes the second information. The configuration information of the first cell may not include the first information. In an embodiment of the present application, the second information is used to determine whether the first cell is suitable for residence. Alternatively, the second information is used to indicate a parameter of whether the first cell is suitable for residence. Alternatively, the first terminal device may determine whether the first cell is suitable for residence based on the parameters in the second information. Optionally, when the configuration information of the first cell includes the second information, the first terminal device assumes that the first cell is not prohibited. That is, the configuration information of the first cell does not include the first information, and the first terminal device assumes that the first cell is not prohibited. In this implementation, the first terminal device may first obtain the second information, and determine whether to send the first signal based on the second information.

[0142] In this implementation, the first terminal device determines whether the first cell is suitable for residence based on the second information. If the first terminal device determines that the first cell is suitable for residence, the first terminal device wakes up the first cell, or the first terminal device requests the transmission of the public signal of the first cell. This can reduce the energy waste of the first network device caused by the first terminal device waking up the first cell that is not suitable for residence, or reduce the energy waste of the first network device caused by the first terminal device requesting the transmission of the public signal of the first cell that is not suitable for residence; further, since the first terminal device assumes that the first cell is not prohibited, the first terminal device does not need to determine whether the first cell is prohibited, thereby simplifying the implementation process of the first terminal device. It can be understood that in this implementation, the second information is necessary information to implement the above process.

[0143] In another possible implementation, the configuration information of the first cell includes the first information. The configuration information of the first cell may not include the second information. In an embodiment of the present application, the first information is used to determine whether the first cell is prohibited. Alternatively, the first information is used to indicate a parameter of whether the first cell is prohibited. Alternatively, the first terminal device may determine whether the first cell is prohibited based on the parameters in the first information. Optionally, in this implementation, the first terminal device may obtain the second information after receiving a common signal (such as a first common signal and a second common signal, or a second common signal) triggered by the first signal. The second information may be carried in a common signal (such as a second common signal). In this implementation, the first terminal device may first obtain the first information and determine whether to send the first signal based on the first information.

[0144] In this implementation, the first terminal device determines whether the cell is prohibited according to the first information. If the first terminal device determines that the first cell is not prohibited, the first terminal device wakes up the first cell, or in other words, the first terminal device requests the transmission of the public signal of the first cell. Therefore, before the first signal is sent, the first terminal device determines whether the first cell is prohibited, which can reduce the energy waste of the first network device caused by the first terminal device waking up the prohibited and / or unsuitable first cell. Further, the first terminal device can obtain the second information after receiving the public signal, and the second information can be included in the public signal. The first terminal device determines whether the first cell is suitable for residence according to the second information, and determines whether to reside in the first cell according to the judgment result. It should be understood that in this implementation, the first cell can correspond to a carrier where the first terminal device is likely to reside, such as a low-frequency carrier. After the first terminal device determines that the first cell is not prohibited according to the first information, it is likely to reside in the first cell. Therefore, before the first signal is sent, the first terminal device does not need to make a residence judgment, which reduces the complexity of the first terminal device needing to make a judgment on whether the first cell is suitable for residence before sending the first signal. It can be understood that in this implementation, the first information is necessary information to implement the above process.

[0145] In an embodiment of the present application, the first information includes at least one of the following: information for indicating one or more frequency bands to which one or more downlink carriers of the first cell belong; information for indicating one or more frequency bands to which one or more uplink carriers of the first cell belong; information for indicating the uplink carrier bandwidth of the first cell; information for indicating the uplink initial part bandwidth (bandwidth part, BWP) bandwidth of the first cell; information for indicating the downlink carrier bandwidth of the first cell; information for indicating the downlink initial BWP bandwidth of the first cell; information for indicating that the first cell requires the first terminal device to be able to perform uplink transmission with an offset of 7.5kHz relative to the LTE grid raster; or, the first information may include other information for determining whether the first cell is prohibited, which is not limited to the embodiment of the present application.

[0146] In an embodiment of the present application, the second information includes at least one of the following: public land mobile network information (PLMN) of the first cell; standalone non-public network information (SNPN) of the first cell; indication information (cell selection criterion S) for determining whether the first cell meets the cell selection criteria; or, the second information may include other information for determining whether the first cell is suitable for residence, which is not limited in the embodiment of the present application.

[0147] Optionally, the configuration information of the first cell also includes configuration information of the first signal. In one possible implementation, the first signal may be a random access preamble, or may be a message 1 (MSG1), or may be a physical random access channel (PRACH), which is not limited in the embodiments of the present application; accordingly, the configuration information of the first signal may include configuration information of PRACH resources. In another possible case, the first signal may be a physical uplink control channel (PUCCH), and exemplarily, the first signal may be a PUCCH for a scheduling request (SR); accordingly, the configuration information of the first signal may include configuration information of PUCCH resources.

[0148] S320, the first terminal device determines whether to send a first signal according to the configuration information of the first cell.

[0149] In an embodiment of the present application, the first signal is used to request the first common signal and / or the second common signal corresponding to the first cell; or, the first signal is used to wake up the network device that sends the first common signal and / or the second common signal; or, the first signal is used to request the network device serving the first cell to send the first common signal and / or the second common signal; or, the first signal is used to wake up the first cell that transmits the first common signal and / or the second common signal, and the embodiment of the present application does not limit this. It should be understood that before the first terminal device sends the first signal for requesting the first common signal and / or the second common signal corresponding to the first cell, the first cell is not awakened, or the network device serving the first cell does not send the first common signal and / or the second common signal. It should be understood that the first common signal and / or the second common signal are used for the first terminal device to access the first cell.

[0150] In an embodiment of the present application, the first common signal and / or the second common signal may include at least one of the following: scheduling information of other system information, counter configuration information, user access control restriction information, terminal recovery identification indication, or other public information, which is not limited in the embodiment of the present application. In a possible implementation, the first common signal and / or the second common signal may not include the configuration information of the first cell described in step S310. That is, the first terminal device has already acquired the configuration information of the first cell described in step S310 before sending the first signal, so there is no need to reacquire it after sending the first signal. In this way, the load of the first common signal and / or the second common signal can be reduced, which is useful for improving the coverage capability of the first common signal and / or the second common signal. It should be understood that the smaller the load of the first common signal and / or the second common signal, the lower the modulation order and coding rate that can be used, and the better the coverage capability of the first common signal and / or the second common signal. In this manner, the first common signal and / or the second common signal may be referred to as a lightweight first common signal and / or a second common signal, or may be a first common signal and / or a second common signal used in an energy-saving mode; in contrast, there is a conventional first common signal and / or a second common signal, and the conventional first common signal and / or the second common signal may be transmitted in a non-energy-saving mode. The conventional first common signal and / or the second common signal includes the configuration information of the first cell described in step S310.

[0151] In another possible implementation, the first common signal and / or the second common signal may include the configuration information of the first cell described in step S310.

[0192] In a possible implementation, corresponding to a multi-cell scenario, such as Figure 4 As shown, it is a schematic diagram of an example of a communication method provided in an embodiment of the present application. The method is explained by taking the interaction between the first terminal device and the first network device as an example. Of course, the subject that executes the action of the first terminal device in the method can also be a device / module in the first terminal device, such as a chip, a processor, a processing unit, etc. in the first terminal device; the subject that executes the action of the first network device in the method can also be a device / module in the first network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiment of the present application does not make specific limitations on this.

Optionally, the configuration information of the first cell may be sent periodically. It should be understood that the configuration information of the first cell is sent in the second cell (optionally, periodically), and therefore, there is no need to send the configuration information of the first cell (optionally, periodically) in the first cell, which can be more conducive to energy saving of the network equipment corresponding to the first cell.

[0197] In a possible implementation, the first cell and the second cell are both served by the first network device. It should be understood that the first cell and the second cell are both served by the first network device, and the first cell and the second cell may be both cells under the first network device.

[0200] S420: The first terminal device determines whether to send a first signal according to the configuration information of the first cell.

[0201] In the embodiment of the present application, regarding whether the first terminal device determines whether to send the first signal based on the configuration information of the first cell, reference may be made to the description of step S320, which will not be repeated here.

[0202] In an embodiment of the present application, when the configuration information of the first cell includes the first information and the second information, the first terminal device first resides in the second cell, or the first terminal device first accesses the second cell. The first terminal device can obtain the first information and the second information in the second cell before sending the first signal to wake up the first cell or requesting the public signal of the first cell, and judge whether the first cell is prohibited and whether the first cell is suitable for residence based on the first information and the second information. If the first terminal device judges that the first cell is not prohibited and the first cell is suitable for residence, the first terminal device wakes up the first cell, or the first terminal device requests the transmission of the public signal of the first cell. After that, the first terminal device will communicate with the first cell. Otherwise, the first terminal device still resides in the second cell or still accesses the second cell.

[0203] In an embodiment of the present application, when the configuration information of the first cell includes the second information, the first terminal device first resides in the second cell, or the first terminal device first accesses the second cell. The first terminal device can obtain the second information in the second cell before sending the first signal to wake up the first cell or requesting the public signal of the first cell, and judge whether the first cell is suitable for residence based on the second information. If the first terminal device judges that the first cell is suitable for residence, the first terminal device wakes up the first cell, or the first terminal device requests the transmission of the public signal of the first cell, and then the first terminal device communicates with the first cell. Otherwise, the first terminal device still resides in the second cell or still accesses the second cell.

[0204] In an embodiment of the present application, when the configuration information of the first cell includes the first information, the first terminal device first resides in the second cell, or the first terminal device first accesses the second cell. The first terminal device can first obtain the first information in the second cell before sending the first signal to wake up the first cell or requesting the public signal of the first cell, and judge whether the first cell is prohibited based on the first information. If the first terminal device determines that the first cell is not prohibited, the first terminal device wakes up the first cell, or the first terminal device requests the transmission of the public signal of the first cell, and then the first terminal device communicates with the first cell. Otherwise, the first terminal device still resides in the second cell or is still accessed in the second cell.

[0205] In the communication method provided by the embodiment of the present application, the first terminal device receives the configuration information of the first cell sent by the first network device, and the first terminal device can determine whether to send a first signal for requesting the first common signal and / or the second common signal corresponding to the first cell according to at least one of the first information or the second information included in the configuration information of the first cell; wherein the first information is used to determine whether the first cell is prohibited, and the second information is used to determine whether the first cell is suitable for residence. In the case where the first cell is prohibited and / or the first cell is not suitable for residence, the first signal is not sent, and the first signal is avoided when the first cell is prohibited and / or the first cell is not suitable for residence, so that the first common signal and / or the second common information of the first cell are still sent and the waste of resources caused. In other words, the communication method provided by the embodiment of the present application is conducive to low-carbon energy saving of network equipment. Further, the configuration information of the first cell is sent in the second cell (optionally, periodically), so that the configuration information of the first cell does not need to be sent in the first cell (optionally, periodically), which can be more conducive to energy saving of the first cell.

[0206] In another possible implementation, corresponding to a single cell scenario, such as Fig. 9As shown, it is a schematic diagram of another example of the communication method provided in an embodiment of the present application. The method is explained by taking the interaction between the first terminal device and the first network device as an example. Of course, the subject that executes the action of the first terminal device in the method can also be a device / module in the first terminal device, such as a chip, a processor, a processing unit, etc. in the first terminal device; the subject that executes the action of the first network device in the method can also be a device / module in the first network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiment of the present application does not make specific limitations on this. The processing performed by a single execution subject (for example, a first terminal device or a first network device) in an embodiment of the present application can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the first network device can be divided into executions by at least one of CU, DU and RU. Exemplary, such as Fig. 9 The method 900 includes:

[0207] S910, the first network device sends configuration information of the first cell to the first terminal device. Correspondingly, the first terminal device receives the configuration information of the first cell from the first network device in the first cell.

[0208] In the embodiment of the present application, the configuration information of the first cell may refer to the description in step S310 and will not be repeated here.

[0209] In the embodiment of the present application, the first terminal device receives the configuration information of the first cell in the first cell. For ease of understanding, the following is given Fig.10 The schematic diagram shown is that a first terminal device receives configuration information of the first cell in a first cell. The first terminal device receives the configuration information of the first cell in the first cell. Further, the first terminal device can determine whether to send a first signal based on the configuration information of the first cell.

[0210] Exemplarily, the configuration information of the first cell is carried in the first message. Exemplarily, the first message is sent periodically, for example, the first message is sent periodically on preconfigured time-frequency resources; Exemplarily, the first message is related to the first common signal. Optionally, the first message is frequency-division multiplexed with the first common signal; Optionally, the first message is scheduled by the first indication information, in other words, the first indication information indicates the time domain and frequency domain resources used to transmit the first message; wherein, the first indication information is carried in the first common signal, or the first indication information is carried in the first physical downlink control channel (PDCCH), and the configuration of the first PDCCH is carried in the first common signal.

[0211] It should be noted that, when the first message carrying the configuration information of the first cell is related to the first common signal, the first common signal is sent before the first terminal device sends the first signal, or, in other words, in this case, in the following step S920, the first signal is used to request the second common signal of the first cell.

[0212] S920, the first terminal device determines whether to send a first signal according to the configuration information of the first cell.

[0213] In the embodiment of the present application, step S920 may refer to the description in step S320 and will not be repeated here.

[0214] In the communication method provided by the embodiment of the present application, the first terminal device receives the configuration information of the first cell sent by the first network device, and the first terminal device can determine whether to send a first signal for requesting a first common signal and / or a second common signal of the first cell according to at least one of the first information or the second information included in the configuration information of the first cell; wherein the first information is used to determine whether the first cell is prohibited, and the second information is used to determine whether the first cell is suitable for residence. In the case where the first cell is prohibited and / or the first cell is not suitable for residence, the first signal is not sent, so as to avoid sending the first signal when the first cell is prohibited and / or the first cell is not suitable for residence, so that the first common signal and / or the second common information of the first cell are still sent and the waste of resources caused. In other words, the communication method provided by the embodiment of the present application is conducive to low-carbon energy saving of network equipment.
