Description
Communication methods and communication devices Technical Field
[0001] This application relates to the field of communications, and more specifically, to communication methods and communication devices. Background Technology
[0002] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. With the widespread adoption of wireless communication network technology across various industries and regions, and its application in more advanced applications and higher-speed services, communication networks are becoming denser, using more antennas, larger bandwidths, and more frequency bands, resulting in greater energy consumption. Energy consumption has become a key component of operators' operating expenses (OPEX), with mobile network energy costs accounting for approximately 23% of operators' total costs, and the majority of this energy consumption originating from the radio access network (RAN). RAN power consumption is divided into two parts: a dynamic component, which refers to the energy consumed during data transmission / reception, and a static component, which refers to the energy consumed to maintain the necessary operation of the wireless network equipment when there is no data transmission / reception.
[0003] Therefore, communication networks need to research solutions to reduce network energy consumption, minimize the environmental impact of network energy consumption, and lower operator costs. Summary of the Invention

[0044] To facilitate understanding, the relevant technologies of the embodiments of this application will be briefly introduced first.
[0045] I. The transmission mechanism of periodically transmitted synchronization signal and physical broadcast channel (PBCH) block (SSB).
[0046] In 5G NR, synchronization signals (including the primary synchronization signal (PSS) and secondary synchronization signal (SSS)) and main information blocks (MIBs, system information transmitted via PBCH) are transmitted in the form of resource blocks, as shown in Figure 1. This resource block is called an SSB. An SSB occupies 4 consecutive symbols in the time domain and 240 consecutive subcarrier intervals (i.e., 240 / 12 = 20 RBs) in the frequency domain. The PSS occupies 127 subcarriers in the first symbol.
[0047] The NR protocol specifies various SSB patterns, which define the temporal location of SSBs under different scenarios (frequency bands, subcarrier spacing). An SSB burst contains multiple SSBs distributed within a half-frame (5ms). The temporal location of SSBs within a half-frame differs depending on the frequency band and subcarrier spacing. The temporal location of SSBs within a half-frame can be obtained through predefined rules. Figure 2 illustrates some SSB patterns. In Figure 2, four consecutive dark-colored squares or four consecutive light-colored squares each constitute an SSB. Case A in Figure 2 represents the SSB distribution when the subcarrier spacing is 15kHz, while cases B and C represent different SSB distributions when the subcarrier spacing is 30kHz.
[0048] Taking scenario A with a subcarrier spacing of 15kHz as an example, a single SSB burst can have a maximum of 4 or 8 SSBs (Lmax = 4 or 8). Taking Lmax = 4 as an example, there can be a maximum of 4 SSBs (index 0 to 3) within a half-frame, and they are distributed in the first two subframes.
[0049] Terminal devices perform beam scanning based on SSBs within a half-frame, meaning there's a one-to-one correspondence between SSBs and beams within a half-frame. The optimal beam direction can be found by determining the index of the optimal SSB. In the NR protocol, for frequency bands below 3 GHz, there are a maximum of 4 SSBs and 4 beams scanned within a half-frame; for frequency bands from 3 GHz to 6 GHz, there are a maximum of 8 SSBs and 8 beams scanned within a half-frame; and for frequency bands above 6 GHz, there are a maximum of 64 SSBs and 64 beams scanned within a half-frame. As shown in Figure 3, there are 8 SSBs (SSB indices 0-7) within a half-frame (5ms), each corresponding to one of the 8 beams. Terminal devices 1 and 2 each perform measurements based on these 8 SSBs. For terminal device 1, the strongest beam is the beam corresponding to SSB1; for terminal device 2, the strongest beam is SSB7.
[0050] During initial cell selection, the SSB period is typically 20ms, meaning the SSB burst is periodic, occurring every 20ms. As shown in Figure 3, an SSB half-frame (SSB burst) occurs every 20ms, with multiple SSBs distributed within each SSB half-frame. Access network equipment can also indicate SSB parameters (e.g., via SIB1), including:
[0051] `ssb-PositionsInBurst` is used to determine the temporal position of an SSB transmitted within an SSB burst. Taking Figure 3 as an example, there are 8 SSBs (SSB indices 0 to 7) within a half-frame (5ms). The terminal device does not need to receive SSBs on all 8 SSBs, and the access network device does not necessarily transmit SSBs on all 8 SSBs. By using `ssb-PositionsInBurst`, it can be determined that the SSBs actually transmitted are the SSBs corresponding to indices 0, 1, 4, and 6. Therefore, the terminal device can receive SSBs at the temporal positions corresponding to indices 0, 1, 4, and 6.
[0052] The ssb-PositionsInBurst can indicate the index of the SSB within the SSB burst using a bitmap. One bit in ssb-PositionsInBurst can correspond to one or more SSB indices. For example, if the bit value is 0, the corresponding SSB is not transmitted; if the bit value is 1, the corresponding SSB is transmitted.
[0053] The number of bits in ssb-PositionsInBurst is related to the maximum number of SSBs within an SSB burst. The specific indication method for ssb-PositionsInBurst can be found in existing protocols and will not be elaborated upon here.
[0054] `ssb-periodicityServingCell` is used to determine the period of the SSB, i.e., the period of the SSB burst. In the embodiments of this application, the period of the SSB burst is simply referred to as the SSB period. The SSB is transmitted in the form of an SSB burst, which is simply referred to as transmitting the SSB in the embodiments of this application.
[0055] ss-PBCH-BlockPower is used to determine the power of the SSS, which is the average EPRE (Energy per resource element) of the SSS.
[0056] It should be noted that the SSB in NR is not always located at the center of the carrier. The frequency domain location of the SSB can be on or off the synchronization raster. For an SSB on the synchronization raster, the terminal device can obtain the SSB by scanning the frequency, i.e., searching for the SSB on the synchronization raster. For an SSB off the synchronization raster (or, SSB not on the synchronization raster), the access network device indicates the frequency domain location of the SSB to the terminal device.
[0057] In carrier aggregation (CA) scenarios, access network equipment can indicate the parameters of the SSB on the secondary cell SCell to the terminal equipment, for example, through RRC signaling. These parameters include:
[0058] The parameter ssb-PositionsInBurst can be found in the description above and will not be repeated here.
[0059] The parameter ssb-periodicityServingCell can be found in the description above and will not be repeated here.
[0060] ssbSubcarrierSpacing is used to determine the subcarrier spacing of the SSB.
[0061] The parameter ss-PBCH-BlockPower can be found in the description above and will not be repeated here.
[0062] II. Non-cell defining-SSB (NCD-SSB).
[0063] There are two types of SSBs: cell defining SSB (CD-SSB) and NCD-SSB.
[0064] CD-SSB refers to an SSB with associated RMSI (SIB1), which means that the RMSI is received through COREST0 in the SSB during the cell search process.
[0065] If an SSB does not include CORESET0, the terminal device cannot receive SIB1. Such an SSB is called an NCD-SSB. Specifically, the MIB in an NCD-SSB does not directly indicate the CORESET (CORESET0) and search space set 0 of the RMSIPDCCH, meaning the terminal device cannot directly camp or access the cell using this type of SSB. NCD-SSBs can be transmitted on or off the GSCN. SSBs on the GSCN can be found by the terminal device. To speed up cell search, the MIB in an NCD-SSB on the GSCN indicates the frequency domain location of the CD-SSB, allowing the terminal device to quickly search for it (as shown in Figure 4). Alternatively, when there are no CD-SSBs within a frequency range, the NCD-SSB can indicate that there are no CD-SSBs within that frequency range, allowing the terminal device to skip that frequency range and search for CD-SSBs, as shown in Figure 4. The NCD-SSCH can be used for RRM measurements.
[0066] 3. On-demand SSB (OD SSB).
[0067] 3.1. NR Rel-15 supports SSB-less Scells for Intra-band CA, allowing terminal devices to perform AGC adjustments and time-frequency synchronization based on SSBs on other carriers within the Intra-band. Rel-18 extends SSB-less Scells to some scenarios of Inter-band CA. However, for Inter-band CA, some scenarios are still unsuitable for SSB-less Scells; therefore, access network devices still need to periodically transmit SSBs. However, the current protocol's SSB supports a maximum transmission period of 160ms, with a typical period of 20ms. Therefore, it is necessary to introduce On-demand SSB Scells to save Scell power consumption. Specifically, the purpose of on-demand SSB for measurement is: 1) If on-demand SSB is configured when the Scell is not active, the terminal device uses on-demand SSB for measurement / reporting. The access network device can select the Scell to be activated based on the measurement results reported by the terminal device, thereby reducing network power consumption and improving the accuracy of Scell activation; 2) on-demand can be used for Scell synchronization, for example, for inter-band CA synchronization. If on-demand SSB continues to be sent after the Scell is activated, it can be used to maintain Scell synchronization. In Rel-19 NR, the OD SSB feature is used for Scells in connected CA scenarios, and OD SSB can be used for L1 / L3 measurements. An Scell primarily undergoes four stages, as shown in Figure 5. Before a cell is configured as an Scell, it can be called a neighboring cell. Phase 1 in Figure 5 indicates that the cell has been configured as an Scell but an activation command has not yet been issued. Phase 2 indicates the Scell activation process, specifically that an activation command has been issued for the Scell, but activation has not yet been completed. Phase 3 indicates that the Scell has been activated, meaning that the Scell can begin normal communication. Unlike traditional SSBs that are sent periodically, OD SSBs indicate that SSBs are sent over a period of time. Within this period, SSBs can be sent periodically; it can be understood that OD SSBs are sent periodically over a certain period.
[0068] 3.2. Parameters of OD SSB.
[0069] The parameters of the OD SSB include: the frequency domain information of the OD SSB, the position of the SSB transmitted within the OD SSB burst (similar to the function of SSB-PositionsInBurst), the period of the OD SSB, the subcarrier spacing of the OD SSB, the cell ID of the OD SSB, and the transmit power of the OD SSB. For example, the parameters of the OD SSB can be configured via RRC signaling.
[0070] The period of the OD SSB can be {5ms, 10ms, 20ms, 40ms, 80ms, or 160ms}, and its period can be configured separately from the period of the periodically transmitted SSB (always on SSB, AO SSB). For example, the period of the OD SSB can be less than or equal to the period of the AO SSB.
[0071] An OD SSB in an Scell can be configured with multiple sets (or more) of parameters, such as the period of the OD SSB. It can also be represented as an Scell configuring multiple OD SSBs, each with its own set of parameters. When an Scell has multiple sets of parameters configured for its OD SSBs, the access network device can further indicate one of the configurations; or, when an Scell has multiple OD SSBs configured, the access network device can further indicate one type of OD SSB. The embodiments of this application do not distinguish between the two description methods. For example, if higher-layer signaling configures multiple OD SSB periods, the access network device can further indicate one type of period.
[0072] The methods for instructing OD SSB transmission and deactivating OD SSB are as follows:
[0073] OD SSB transmissions are triggered by access network equipment. Indicating an OD SSB transmission can be understood as activating or triggering an OD SSB transmission. The signaling indicating an OD SSB transmission can be RRC signaling or MAC CE signaling. In existing protocols, Scell activation / deactivation can be achieved through RRC signaling, MAC CE signaling, or timer-based methods (for Scell deactivation). There are two methods for triggering (or activating) an OD SSB:
[0074] Method 1: Different signaling (e.g., RRC and MAC CE) respectively indicate Scell activation / deactivation and OD SSB transmission;
[0075] Method 2: The same signaling indicates Scell activation / deactivation and OD SSB transmission.
[0076] For the method of OD SSB transmission based on RRC signaling, the RRC signaling simultaneously configures the Scell, activates the Scell, and configures the OD SSB configuration information.
[0077] IV. The mechanism of SSB adaptive adjustment.
[0078] Another mechanism to reduce SSB transmission is SSB adaptation, which involves adjusting the period of the SSB burst. There can be multiple SSB burst periods, and the access network equipment instructs the adjustment of the SSB burst period. The SSB frequency domain position remains the same before and after adjustment, and the QCL relationship remains unchanged. This mechanism is used for Scells in RRC connected state. The SSB in this mechanism can be an NCD SSB on / off synchronization raster.
[0079] V. Activation or deactivation of DTX and / or DRX
[0080] To save power consumption of access network equipment, 3GPP introduced the Cell DTX (hereinafter referred to as DTX in this embodiment) and Cell DRX (hereinafter referred to as DRX in this embodiment) mechanisms. That is, the access network equipment only performs uplink / downlink transmission with the terminal equipment during specific time periods, and does not perform uplink / downlink transmission during other time periods, so as to achieve energy saving of the access network equipment.
[0081] It is important to note that Cell DTX and C-DRX are two different mechanisms.
[0082] Access network equipment configures DTX and / or DRX parameters for terminal equipment. These parameters include the DTX and / or DRX period, offset value, and / or the length of the DTX and / or DRX activation timer. To save power consumption of access network equipment, these parameters are typically the same for multiple terminal equipment within the cell.
[0083] One cycle of Cell DTX can include both the active and inactive periods of Cell DTX. Similarly, one cycle of Cell DRX can include both the active and inactive periods of Cell DRX.
[0084] For a given cell, during the active (ON) period of Cell DTX, the access network device can normally send signals to the terminal device. During the inactive (OFF) period of Cell DTX, the access network device does not send certain signals to conserve power; correspondingly, the UE does not receive the corresponding signals. During the active (ON) period of Cell DRX, the access network device can receive signals from the terminal device. During the inactive (OFF) period of Cell DRX, the access network device does not receive certain signals to conserve power; correspondingly, the UE does not send the corresponding signals. For a detailed description, please refer to the description in the Rel-18 TS 38.321 protocol.
[0085] When DTX is active, it means that the access network device can send signals to the terminal device normally during the active period of Cell DTX. During the inactive period of Cell DTX, the access network device does not send any signals. When DTX is deactivated, it means that the DTX mechanism is turned off, and communication between the access network device and the terminal device does not distinguish between the active and inactive periods of Cell DTX; the access network device can always send signals to the terminal device normally. When DRX is active, it means that the access network device can receive signals from the terminal device normally during the active period of Cell DRX. During the inactive period of Cell DRX, the access network device does not receive any signals. When DRX is deactivated, it means that the DRX mechanism is turned off, and communication between the access network device and the terminal device does not distinguish between the active and inactive periods of Cell DTX; the access network device can always receive signals from the terminal device normally.
[0086] Figure 6 is a schematic diagram of a communication system provided in an embodiment of this application. As shown in Figure 6, the communication system provided in an embodiment of this application includes access network equipment and terminal equipment.
[0087] In one possible implementation, if the first condition is met, the access network device is used to activate one or more parameters in the first configuration information; the terminal device is used to receive the first SSB and determine the synchronization information based on the first SSB.
[0088] The first configuration information is included in the first synchronization signal and broadcast information block (SSB) configuration set indicated by the access network device. The first configuration set includes at least one first SSB configuration, and each of the at least one first SSB configurations includes one or more of the following parameters:
[0089] The first parameter is used to indicate the temporal location of the first SSB burst set;
[0090] The second parameter is used to indicate the frequency domain location of the first SSB;
[0091] Alternatively, a third parameter may be included, which may include one or more of the following: the location of the first SSB within the first SSB burst, the number of first SSBs within the first SSB burst, the period of the first SSB, or the downlink transmission power of the first SSB.
[0092] The first SSB is an SSB signal sent on demand.
[0093] In another possible implementation, the access network device is configured to send one or more of the following to the terminal device: a first downlink control information (DCI), or a DCI in the same format as the first DCI, wherein the first DCI is used to indicate the activation or deactivation of DTX and / or DRX; the terminal device is configured to receive one or more of the above from the access network device and perform operations according to the instructions of the one or more of the above.
[0094] Among them, the DCIs with the same format as the first DCI include: a second DCI, used to indicate the adjustment information of the synchronization signal and the broadcast information block SSB; or a third DCI, used to trigger the first SSB, which is an SSB sent on demand.

The access terminal may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, drone, robot, point of sale (POS) machine, customer-premises equipment (CPE), or wearable device, virtual reality (VR) device. Wireless terminals can be categorized into various types, including VR (Augmented Reality) terminal devices, wireless terminals in industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, and smart home. Alternatively, a terminal can be a communication-enabled terminal within the Internet of Things (IoT), such as a V2X terminal (e.g., vehicle-to-everything (V2X) terminal, a D2D communication terminal, or an M2M communication terminal. Terminals can be mobile or fixed. Furthermore, this application does not limit the device form of the terminal; the apparatus used to implement the terminal device's function can be the terminal device itself, or it can be an apparatus capable of supporting the terminal device in implementing that function, such as a chip system.

[0097] In some possible scenarios, access network equipment can also be modules or units capable of implementing some of the functions of a base station. For example, the first network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and DU can be set up separately or included in the same network element, such as in a baseband unit (BBU). The RU can be included in radio equipment or radio units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0098] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, an access network device can be a network device or a module of a network device in an Open Radio Access Network (ORAN) system. In an ORAN system, CU can also be called open (O)-CU, DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU.

[0113] The communication method provided in the embodiments of this application will now be described with reference to the communication system shown in Figure 6.
[0114] It should be noted that in the following embodiments of this application, the message names, parameter names, or information names between network elements are just examples. Other names may also be used in other embodiments. The communication method provided in this application does not specifically limit these names.
[0115] It is understood that in the embodiments of this application, each network element can execute some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application can also perform other operations or variations of various operations. Furthermore, the steps can be executed in different orders as presented in the embodiments of this application, and it is not necessary to execute all the operations in the embodiments of this application.
[0116] It should be noted that SSB, AO SSB, and OD SSB mentioned in the following embodiments can also be replaced with synchronization signal, AO synchronization signal, OD synchronization signal, or other names. This application embodiment does not limit this.
[0117] Figure 8 is a schematic diagram of an example of the communication method provided in this application embodiment. This method can be applied to the communication system shown in Figure 6, and is illustrated using the interaction between an access network device and a terminal device as an example. Of course, the entity executing the action of the access network device in this method can also be a device / module within the access network device, such as a chip, processor, or processing unit within the access network device; similarly, the entity executing the action of the terminal device in this method can also be a device / module within the terminal device, such as a chip, processor, or processing unit within the terminal device. This application embodiment does not specifically limit this. In this application embodiment, the processing performed by a single executing entity (e.g., the access network device or the terminal device) can also be divided into multiple executing entities, which can be logically and / or physically separated. For example, as shown in Figure 8, taking the terminal device access network device as an example, method 800 includes the following steps:
[0118] S810, the access network device activates one or more parameters in the first configuration information.
[0119] In this embodiment of the application, the first configuration information is included in the first SSB configuration set indicated by the access network device. The first SSB configuration set includes at least one first SSB configuration, and each of the at least one first SSB configuration includes one or more of the following parameters:
[0120] The first parameter is used to indicate the temporal location of the first SSB burst set;
[0121] The second parameter is used to indicate the frequency domain location of the first SSB;
[0122] Alternatively, a third parameter may be included, which may include one or more of the following: the location of the first SSB within the first SSB burst, the number of first SSBs within the first SSB burst, the period of the first SSB, or the downlink transmission power of the first SSB.
[0123] It should be noted that the period of the first SSB refers to the period of the first SSB burst set.
[0124] For example, the period of the first SSB can be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, or other period values. This application embodiment does not limit this.
[0125] Optionally, the SCS of the first SSB configured in the first SSB configuration set can be the same or different, and this application embodiment does not limit this.
[0126] In one possible implementation, the indication information of the first SSB configuration set can be carried in a newly added higher-level message. In another possible implementation, the indication information of the first SSB configuration set can be carried in an existing higher-level message; this embodiment of the application does not limit this. Optionally, the aforementioned first parameter, second parameter, and third parameter can be configured through a higher-level message, which can be an existing message or a newly added message; this embodiment of the application does not limit this.
[0127] In this embodiment of the application, if the first condition is met, the access network device activates the first configuration information; or, the access network device may activate one or more parameters in the first configuration information based on other information or by actively activating them. This embodiment of the application does not limit this.
[0128] In one possible implementation, the first condition includes one or more of the following: the transmission scenario is a low-load scenario, the transmission scenario is a high-load scenario, or the secondary cell is configured but not activated.
[0129] In another possible implementation, the first condition may include:
[0130] The terminal device sends the first information to the access network device. Correspondingly, the access network device receives the first information from the terminal device.
[0131] The first information may include one or more of the following: SSB measurement information, Channel State Information (CSI), Channel Quality Information (CQI), or Sounding Reference Signal (SRS). For example, the access network device may adjust one or more of the first parameter, second parameter, and third parameter based on the first information.
[0132] Optionally, the measurement information of SSB can be the signal strength of SSB, such as RSRP / RSRQ / SINR, or beam quality indication, which is not limited in this embodiment.
[0133] Optionally, CQI may include broadband CQI or subband CQI, which is not limited in this embodiment.
[0134] Optionally, the transmission period, time domain location, frequency domain location, transmission power, and antenna port of the SRS mentioned above are transmitted by the access network device at the current moment. The transmission method can be periodic, non-periodic, or semi-persistent. This application embodiment does not limit this.
[0135] In this embodiment, the first SSB can be the OD SSB signal in the aforementioned related technologies, or it can be other names. This embodiment does not limit this.
[0136] In another possible implementation, the first condition includes predefined rules. For example, when the Scell is configured but no activation signaling is indicated, the period of the first SSB is A1, the transmit power is B1, the time domain position is C1, and the frequency domain position is D1; after the Scell is activated, the period of the first SSB is A2, the transmit power is B2, the time domain position is C2, and the frequency domain position is D2. This method can be understood as an implicit indication method.
[0137] Alternatively, as a possible implementation, the access network device can activate one or more parameters in the first configuration information based on predefined rules and first information. For example, the access network device can activate one or more parameters in the first configuration information based on SRS measurement results and a predefined period A1.
[0138] Optionally, the communication method provided in this application embodiment further includes:
[0139] The access network device sends the first signaling to the terminal device. Correspondingly, the terminal device receives the first signaling from the access network device.
[0140] In this embodiment, the first signaling is used to indicate one or more parameters in the activated first configuration information. The first signaling can be a UE-specific DCI or a group-common DCI; this embodiment does not limit its use. Alternatively, the first signaling can be MAC CE signaling or other signaling; this embodiment does not limit its use either.
[0141] Optionally, if a secondary cell is configured but not activated, the first signaling is used to activate one or more parameters in the first configuration information, including: the first signaling is used to activate one or more of the following in the first configuration information: a first parameter, or the period of the first SSB in the third parameter. It should be noted that other parameters in the first configuration information can be predefined. For example, the time-domain location of the first SSB burst is related to the period of the first SSB, the reference point of the SFN offset satisfies (SFN index*10)modulo(OD SSB periodicity) = 0, and the period is 40ms.
[0142] Optionally, when indicating activation of the secondary cell but the secondary cell is not activated, the first signaling is used to activate one or more parameters of the first configuration information, including: the first signaling is used to activate one or more of the following in the first configuration information: a first parameter, or the period of the first SSB in the third parameter. It should be noted that other parameters in the first configuration information can be predefined. This period is inconsistent with the aforementioned periods. For example, if the period of the first SSB changes from 80ms to 20ms, the access network device can detect the CSI information reported by the terminal device based on the first SSB more frequently, accelerating the activation of the secondary cell.
[0143] Optionally, after the secondary cell is activated, the first signaling is used to activate one or more parameters in the first configuration information, including: the first signaling is used to activate the period of the first SSB in the third parameter of the first configuration information. It should be noted that the other parameters in the first configuration information can be predefined. For example, to maintain synchronization, when there is no second SSB in the system (i.e., the periodically transmitted SSB described below), the first signaling activates the period corresponding to the first SSB in the third parameter, for example, 5ms; when there is a second SSB in the system, depending on the period configuration of the second SSB, the first signaling activates the period configuration of the first SSB in the third parameter that is shorter than the period of the second SSB.
[0144] Optionally, for the same center frequency, the number of first SSBs included in the first SSB burst activated by the first signaling can be different. For example, the number of first SSBs included in the first SSB burst can be 4 or 8. This application embodiment does not limit this.
[0145] Optionally, after the secondary cell is activated, the first signaling is used to activate one or more parameters in the first configuration information, including: the first signaling is used to activate the downlink transmission power of the first SSB in the third parameter of the first configuration information. For example, the access network device can determine the adjusted downlink transmission power based on the SRS sent by the terminal device in different scenarios, or the CSI reported by the terminal device. This application embodiment does not limit this.
[0146] Wherein, the downlink transmission power of the first SSB in the first configuration information is less than the downlink transmission power of the first SSB activated at the previous time, or the downlink transmission power of the first SSB in the first configuration information is greater than the downlink transmission power of the first SSB activated at the previous time.
[0147] The type of the first signaling can be UE-specific DCI, group-common DCI, or MAC CE signaling; this embodiment does not limit this. It should be noted that the type of the first signaling may differ or be the same depending on the parameters activated; this embodiment does not limit this.
[0148] In S820, the access network device sends the first SSB to the terminal device. Correspondingly, the terminal device receives the first SSB from the access network device.
[0149] S830, the terminal device determines the synchronization information based on the first SSB.
[0150] The communication method provided in this application embodiment enables an access network device to activate one or more parameters in the first configuration information according to a first condition. The access network device then sends a first SSB according to the parameter, so that the terminal device can determine the synchronization information according to the first SSB and thus complete the synchronization.
[0151] Optionally, the communication method provided in this application embodiment further includes:
[0152] The access network device determines the temporal location of the first SSB burst set based on one or more of the following: the half-frame location of the first SSB, or the first temporal offset of the first SSB, wherein the first temporal offset is determined based on the period of the first SSB, and / or the period of the second SSB.
[0153] In one possible implementation, the first time-domain offset satisfies the following relationship for the SFN:
[0154] (SFN index*10)modulo(max{OD SSB periodicity,AO SSB periodicity})=0
[0155] Wherein, SFN index represents the system frame number index, max{OD SSB periodicity,AO SSB periodicity} represents the maximum value between the periods of the first SSB and the second SSB, and modulo represents the modulus.
[0156] In another possible implementation, the first time-domain offset satisfies the following relationship for the SFN:
[0157] (SFN index*10)modulo(min{OD SSB periodicity,AO SSB periodicity})=0
[0158] Wherein, SFN index represents the system frame number index, min{OD SSB periodicity,AO SSB periodicity} represents the minimum value between the periods of the first SSB and the second SSB, and modulo represents the modulus.
[0159] In another possible implementation, the first time-domain offset satisfies the following relationship for the SFN:
[0160] (SFN index*10)modulo(AO SSB periodicity)=0
[0161] Wherein, SFN represents the system frame number index, AO SSB periodicity represents the period of the second SSB, and modulo represents the modulus.
[0162] Alternatively, the temporal position of the first SSB burst set can also be a value in a fixed value set, such as 2.5ms or 7.5ms, which is independent of the period of the first and second SSBs. In one possible implementation, the fixed value set can be a set of integer multiples other than 5ms.
[0163] It should be noted that the methods described above for determining the temporal location of the first SSB burst set can form an independent scheme.
[0164] When only the first SSB is transmitted in the system, and when both the first and second SSBs are transmitted in the system, it is necessary to discuss the reporting of measurement results from the terminal device to the access network device under different circumstances. Optionally, the communication method provided in this application embodiment further includes:
[0165] The terminal device sends the first measurement result to the access network device. Correspondingly, the access network device receives the first measurement result from the terminal device.
[0166] In this embodiment of the application, the first measurement result is obtained by the terminal device by measuring one or more of the following: the first SSB corresponding to the first configuration information, or the second SSB, wherein the second SSB is an SSB signal periodically sent by the access network device.
[0167] It should be noted that the second SSB can be the AO SSB signal in the aforementioned related technologies, or it can be other names. This application embodiment does not limit this.
[0168] Optionally, the first measurement result may be the terminal device measuring the first SSB (corresponding to case one), or the terminal device measuring the first SSB and the second SSB to obtain the CSI (corresponding to case two), or other channel information. This application embodiment does not limit this.
[0169] Optionally, the measured resources include the time-domain location of the first SSB, and / or the resources corresponding to the frequency-domain location (corresponding to case one).
[0170] Optionally, the measured resources include the time-domain locations of the first SSB and the second SSB, and / or the resources corresponding to the frequency-domain locations (corresponding to case two).
[0171] In this embodiment of the application, in case two, the terminal device's measurement of the first SSB and the second SSB satisfies the first rule:
[0172] The first SSB and the second SSB are located at the same center frequency. The resources corresponding to the frequency domain position of the first SSB are measured, or the resources corresponding to any frequency domain position of the second SSB and the first SSB are measured. Specifically, the access network equipment can instruct the terminal equipment to perform measurements on the BWP where the first SSB is located, or to perform measurements on the entire carrier bandwidth. For interference measurements on the first SSB, new measurement methods can be used, such as measuring interference in the out-of-band or spurious regions of the first SSB. It should be noted that no NR signal is transmitted during the resource measurements.
[0173] Alternatively, if there is a time-domain conflict between the first SSB and the second SSB, the first SSB and the second SSB are measured according to the first reception priority of the terminal device for the first SSB and the second SSB.
[0174] In one possible implementation, the first priority includes receiving the second SSB first, followed by receiving the first SSB. Optionally, this first receiving priority is determined based on a second condition.
[0175] The second condition includes one or more of the following:
[0176] The secondary cell is not activated, the secondary cell is configured but not activated (i.e., the scenario is classified), the second SSB satisfies the first time domain position, the second SSB satisfies the first period, the second SSB satisfies the first transmission power, or the first duration is less than the first threshold (i.e., the parameters are limited); wherein, the first duration is the duration from the start of transmission of the first SSB actually received by the terminal device to the deactivation of the first configuration information, or the first duration is the duration from the activation of the secondary cell to the deactivation of the first configuration information.
[0177] For example, for a second SSB with a period of 20ms, if the period of the second SSB is not adjusted and updated, the second SSB will be received first in the event of a conflict.
[0178] For example, the terminal device expects the first SSB to be transmitted starting from instance A, where instance A represents the actual time unit for transmitting the first SSB (this time unit can be, for example, a time slot), and the time from instance A to the deactivation of the first configuration information is T. When T is greater than, less than or equal to a first threshold, the second SSB is received preferentially.
[0179] For example, the value of T includes the time T1 from Instance A to Scell deactivation, and the time T2 from Scell deactivation to the first configuration information deactivation. Within T1, the first SSB is received first, and within T2, the second SSB is received first.
[0180] In another possible implementation, the first reception priority includes receiving the first SSB first, followed by the second SSB. Optionally, this first reception priority is determined based on a third condition.
[0181] The third condition may include one or more of the following:
[0182] After the secondary cell is activated, before the first SSB is transmitted, the period of the second SSB is greater than or equal to that of the first SSB, or the first duration is greater than or equal to the first threshold; wherein, the first duration is the duration from the start of transmission of the first SSB actually received by the terminal device to the deactivation of the first configuration information, or the first duration is the duration from the activation of the secondary cell to the deactivation of the first configuration information.
[0183] For example, when the period of the first SSB is shorter than the period of the second SSB, the first SSB is received first. For instance, if the period of the first SSB is 5ms and the period of the second SSB is 80ms, then in the event of a conflict, the first SSB is received first.
[0184] In another possible implementation, the communication method provided in this application embodiment further includes:
[0185] The access network device sends a first indication message to the terminal device. Correspondingly, the terminal device receives the first indication message from the access network device.
[0186] In this embodiment of the application, the first indication information is used to indicate the first receiving priority, which is determined by the access network device based on the configuration information of the second SSB and the first configuration information.
[0187] Optionally, the first indication information can be MAC CE signaling or DCI signaling. The first indication information and the first signaling can be the same message or different messages; this embodiment does not limit this.
[0188] For example, the period of the first SSB is 80ms and the period of the second SSB is 20ms. The access network device can predict the time domain location of the conflict based on the time domain location of the conflicting SSB signal and the second SSB, and tell the terminal device the SSB to be received first through explicit or implicit means.
[0189] For example, when the frequency domains of the first SSB and the second SSB are different and there is a time domain conflict, the access network device may choose not to send the second SSB. Optionally, the access network device may indicate to the terminal device that it will not send the second SSB.
[0190] Alternatively, as one possible implementation, the first reception priority is determined based on the SSB received at the previous time.
[0191] For example, the SSB received at the collision location can be predefined based on the SSB received at the previous moment. For instance, if the SSB received at the previous moment was the first SSB, then the SSB received at the current collision moment will also be the first SSB.
[0192] Alternatively, as a possible implementation, it can be predefined that when the period of the second SSB is greater than the period of the first SSB, the first SSB should be received first, or when the period of the second SSB is less than the period of the first SSB, the first SSB should be received first.
[0193] Alternatively, it can be predefined that no SSB will be accepted when a conflict occurs, or there may be other methods, which are not limited in this application embodiment.
[0194] In this embodiment of the application, the first measurement result may include one or more of the following: the CQI of the first SSB, the PMI of the first SSB, the RI of the first SSB, the CRI of the first SSB, or the LI of the first SSB.
[0195] For example, a terminal device may report only CQI; or, a terminal device may report CQI, PMI, and RI; or, a terminal device may report one or more of RSRP, RSSI, and RSRQ.
[0196] For example, before Scell is activated, the measurement content is RSRP, and it should be noted that this measurement content does not consider the influence of interference and noise; after Scell is activated, the measurement content is RSSI.
[0197] For scenario one: After the secondary cell is configured but before it is activated, the reporting type corresponding to the first measurement result includes: periodic reporting or semi-continuous reporting.
[0198] Optionally, the reporting period for periodic reporting is configured by the access network device to the terminal device via RRC signaling or MAC CE signaling.
[0199] Optionally, the semi-persistent reporting is triggered by the access network device via MAC CE signaling.
[0200] For scenario two: After the secondary cell is activated, the reporting type corresponding to the first measurement result includes: semi-continuous reporting or non-periodic reporting.
[0201] Optionally, the semi-persistent reporting is triggered by the access network device via MAC CE signaling.
[0202] Optionally, the aperiodic reporting is triggered by the access network device via DCI signaling.
[0203] In this embodiment of the application, the reporting mode of the first measurement result is determined based on one or more of the following: the period of the first SSB, the reporting mode of the second SSB, or a predefined rule.
[0204] In this embodiment, the first measurement result is transmitted via PDCCH and / or PUSCH. For example, the first measurement result can be reported via PUCCH format 0 to 4.
[0205] It should be noted that the above steps can form an independent solution. Specifically, the section on the first priority can also form an independent solution.
[0206] Optionally, in the embodiments of this application, the first SSB and NR signals may conflict. The solution to the conflict between the first SSB and NR signals is described below.
[0207] In this embodiment of the application, the first SSB and NR signals are received by the terminal device based on the second priority, wherein the first transmission resources for transmitting the NR signal conflict with the resources for transmitting the first SSB.
[0208] The first transmission resource may be, for example, a resource for transmitting PDSCH, PDCCH, DMRS, CSI-RS, or uplink symbols, etc., and this application embodiment does not limit this.
[0209] In one possible implementation, the second reception priority includes: receiving the first SSB and ignoring the NR signal.
[0210] Optionally, the second receiving priority is determined by the terminal device based on a fourth condition, which may include one or more of the following:
[0211] This occurs after the secondary cell is configured but before it is activated. For example, in the event of a conflict, the transmission resources of the first SSB may override the first transmission resources; for instance, the uplink symbol may be changed to a downlink transmission symbol.
[0212] This occurs after the secondary cell is activated but before the first configuration information is activated. For example, in the event of a conflict, the first transmission resource is ignored.
[0213] Alternatively, before the first configuration information is activated, prior to the first time point. For example, ignore the first transmission resource in case of a conflict.
[0214] The first duration is the time from the start of transmission of the first SSB actually received by the terminal device to the deactivation of the first configuration information, or the first duration is the time from the activation of the secondary cell to the deactivation of the first configuration information. The first time node can be Instance A as described above.
[0215] In another possible implementation, the second reception priority includes: receiving the NR signal and ignoring the first SSB.
[0216] Optionally, the second receiving priority is determined by the terminal device based on a fifth condition, which includes one or more of the following:
[0217] Before the secondary cell is activated, or after the primary configuration information is deactivated.
[0218] In this embodiment of the application, for the aforementioned lost first transmission resource, the access network device can reschedule the first transmission resource:
[0219] Optionally, in one possible implementation, the communication transmission provided in this application embodiment further includes:
[0220] The terminal device sends HARQ-NACK information corresponding to the NR signal to the access network device. Correspondingly, the access network device receives the HARQ-NACK information corresponding to the NR signal from the terminal device.
[0221] Furthermore, the access network equipment reconfigures the first transmission resource based on the HARQ-NACK information.
[0222] For example, the first transmission resource is a PDSCH resource. The terminal device sends a NACK to the access network device through PUCCH or PDSCH within the time slot specified by PDCCH. The access network device receives the NACK within the specified time slot and determines the reason why the first transmission resource was not successfully received according to the configuration parameters of the first SSB, and reschedules the conflicting first transmission resource.
[0223] Alternatively, in another possible implementation, the communication method provided in this application embodiment further includes:
[0224] Access network equipment reconfigures the primary transmission resources before the secondary cell is activated.
[0225] For example, after an Scell is activated, the terminal device may detect a PDCCH on the same Scell while instance A begins receiving the first SSB. This PDCCH is used to notify the terminal device of Scell deactivation or the first configuration information deactivation message. The transmission of the first SSB may then conflict with the PDCCH, causing the terminal device to fail to receive the Scell deactivation or first configuration information deactivation message in a timely manner. Therefore, the access network device needs to reschedule PDCCH resources or re-indicate the updated parameters in the first configuration information.
[0226] In this embodiment of the application, to avoid conflicts with the first transmission resource, the access network device can configure a transmission window for the first SSB. This transmission window refers to the window through which the terminal device receives the first SSB. When this window fails, even if the access network device sends the first SSB, the terminal device does not need to receive it.
[0227] In one possible implementation, under the high-load scenario described in the above embodiments, the access network device can reduce the transmission window of the first SSB and decrease the transmission time of the first SSB; conversely, under the low-load scenario described in the above embodiments, the access network device can extend the transmission window of the first SSB and reduce the transmission frequency of the first SSB. That is, corresponding to the above embodiments, the access network device can activate the first configuration information with reference to the above scenario, or, after activating the first configuration information, the access network device can reconfigure the transmission resources of the first SSB. Optionally, the communication method provided in this application embodiment further includes:
[0228] The access network device sends a second signaling message to the terminal device. Correspondingly, the terminal device receives the second signaling message from the access network device.
[0229] In the embodiments of the present application, the second signaling is used to reconfigure the transmission resource of the first SSB, and the reconfigured transmission resource of the first SSB is different from the first transmission resource. That is, to avoid conflict, the access network device reconfigures a transmission resource different from the first transmission resource for the first SSB. For example, the access network device may reconfigure one or more of the following parameters of the first SSB through the second signaling: time domain position, frequency domain position, or the number of first SSBs included in the first SSB burst set, etc. For another example, the time domain position of the first SSB may be adjusted. For example, the setting of the reference point satisfies (SFN index*10)modulo(X*OD SSB periodicity)=0, where X is a scaling factor satisfying 0<X≤1, and X is used to adjust the SFN starting reference point of the first SSB, thereby adjusting the time domain position of the first SSB; or, the time domain position of the first SSB is delayed, for example, a predefined delay is configured (e.g., the next slot or the next half frame).
[0230] Wherein, the second signaling may be RRC signaling, or the second signaling may also be DCI signaling, or the second signaling may also be MAC-CE signaling, or the second signaling is other newly added or existing signaling, which is not limited in the embodiments of the present application.
[0231] In another possible implementation, the access network device may suspend the transmission of the first SSB. For example, when the secondary cell is configured but not activated, if a conflict occurs, the access network device may suspend the transmission of the first SSB.
[0232] Alternatively, in the embodiments of the present application, to avoid conflict with the transmission resource of the first SSB, the first transmission resource may be optimized.
[0233] In a possible implementation, the protocol predefines that the first transmission resource is different from one or more of the following: the transmission resource of the first SSB, or the transmission resource of the second SSB signal.
[0234] Optionally, when there is no second SSB transmission in the air interface, that is, only NR signals and the first SSB are transmitted, it may be predefined that the first transmission resource is different from the transmission resource of the first SSB.
[0235] For example, the protocol specifies that the transmission of NR signals is suspended in time slots where the first SSB is transmitted, while NR signals can continue to be transmitted in other time slots. For another example, the protocol specifies that transmission of NR signals is avoided in the frequency domain resources where the first SSB is transmitted, while NR signals can be transmitted in other frequency domain resource positions.
[0236] Optionally, when there is a second SSB transmission in the air interface, i.e. there is an NR signal, the first SSB and the second SSB transmission can be predefined to have different transmission resources than the first SSB and the second SSB.
[0237] For example, the protocol stipulates that NR signal transmission is suspended in the time slot of the first SSB transmission and the time slot of the second SSB transmission, while NR signal transmission can continue in other time slots; as another example, the protocol stipulates that NR signal transmission is avoided in the frequency domain resources of the first SSB transmission and the second SSB transmission (the frequency domain resources of the first SSB and the second SSB can be the same or different), while NR signal transmission can be carried out in other frequency domain resource locations.
[0238] Furthermore, the range of the time-frequency domain position of the CORESET configuration of the first transmission resource can be predefined.
[0239] Optionally, the communication method provided in this application embodiment further includes:
[0240] The access network device sends a third indication message to the terminal device. Correspondingly, the terminal device receives the third indication message from the access network device.
[0241] In this embodiment of the application, the third indication information is used to indicate the CORESET configuration of the transmission resources of the first SSB.
[0242] The CORESET configuration includes one or more of the following: the frequency domain offset value of the CORESET of the first transmission resource, or the duration of the CORESET of the first transmission resource.
[0243] Specifically, the protocol stipulates that the range of the CORESET's time-frequency domain location is further limited based on the time-frequency domain parameters and time-domain location of the configured first SSB. Access network devices can adjust the time-domain and / or frequency-domain location of the CORESET to avoid overlap with the time-domain and / or frequency-domain location of the first SSB. By dynamically adjusting the CORESET configuration and the PDCCH listening position, PDSCH resources are further optimized to avoid conflicts between the first SSB and the first transmission resources. For example, the CORESET's time-frequency domain location can be configured through dedicated RRC messages or newly added RRC messages.
[0244] For example, for the first configuration parameter of the first SSB or the first transmission resource, frequencyDomainResources = 00011111111111… corresponds to a CORESET offset of 3*6 PRBs, and 11*6 consecutive PRBs; Duration = 3, then the time-domain occcasion will last for 3 OFDM symbols; for the second configuration parameter of the first SSB or the first transmission resource, frequencyDomainResources = 00011111111111… corresponds to a CORESET offset of 3*6 PRBs, and 11*6 consecutive PRBs (remaining unchanged); Duration = 1, then the time-domain occcasion will last for 1 OFDM symbol.
[0245] In addition to avoiding the conflict between the first SSB signal and the first transmission resource by using the resource location of CORESET, the conflict between the first SSB signal and the first transmission resource can also be avoided by searching the resource location of the space set, which is not limited here.
[0246] It should be noted that the above-mentioned solutions for the conflict between the first SSB and NR signals can form a separate implementation.
[0247] In this embodiment of the application, when the first SSB transmission introduces inter-cell interference, the following method provides relevant solutions to the impact of HARQ and rate matching, power control and rate matching on the first SSB transmission parameter configuration and transmission process.
[0248] In this embodiment, the terminal device receives the Scell activation signaling in slot n and completes Scell activation no later than n + Scell activation delay, where the Scell activation delay is (THARQ + Tactivation_time + TCSI_Reporting) / NR slot length. Here, represents the HARQ-ACK feedback time. The access network device determines whether to retransmit the Scell activation signaling based on the HARQ feedback signaling.
[0249] Alternatively, after receiving the first signaling for MAC CE configuration in slot n, the actual transmission location of the first SSB receiving the first SSB is Instance A, where the time interval between instance A and slot n is T>=+1, and m represents the HARQ-ACK feedback time. The access network device determines whether to retransmit the first signaling based on the HARQ feedback signaling.
[0250] When a terminal device receives a NACK response due to interference from a neighboring cell, the access network device needs to retransmit the Scell activation signaling.
[0251] Optionally, the communication method provided in this application embodiment further includes:
[0252] The terminal device sends a first feedback message to the access network device. Correspondingly, the access network device receives the first feedback message from the terminal device.
[0253] In this embodiment of the application, the first feedback information is used to indicate a first information error. The first information includes one or more of the following: first signaling, or activation signaling of the secondary cell.
[0254] Furthermore, the communication method provided in this application embodiment also includes: the access network device retransmitting the first information based on the first feedback information.
[0255] Specifically, when the terminal device receives the Scell activation signaling or the first signaling, if the CRC check fails, it sends a NACK within the specified HARQ feedback time. The access network device then sends a new redundant version based on the feedback result, selecting a different subset of bits from the circular buffer for transmission. This new redundant version is generated based on one or more parameters from the Scell activation configuration and the first configuration information indicated by the first signaling, and is stored in the circular buffer.
[0256] Optionally, in this embodiment of the application, the access network device retransmits the first information based on the first feedback information, including:
[0257] The access network device determines redundant first information from the circular buffer based on the first feedback information, wherein the redundant first information includes one or more of the following: parameters related to the first configuration information activated by the first signaling indication, or parameters related to the configuration of the secondary cell activated by the activation signaling indication of the secondary cell.
[0258] Furthermore, the access network device sends redundant first information.
[0259] Optionally, the updated redundant first information is the same as the initial redundant information of the first information sent by the access network device to the terminal device at the next moment.
[0260] Specifically, when the terminal device fails to receive the Scell activation signaling and successfully retransmits it, the access network device selects the redundant version corresponding to the retransmission of the Scell activation signaling during the initial transmission when configuring one or more parameters of the first configuration information, so as to avoid additional resource overhead caused by the retransmission of the first signaling.
[0261] Optionally, the communication method provided in this application embodiment further includes:
[0262] The terminal device sends channel quality reporting information to the access network device. Correspondingly, the access network device receives the channel quality reporting information from the terminal device.
[0263] The access network equipment determines one or more of the following for the first SSB and / or the second SSB based on the channel quality reporting information: transmit power, or rate matching parameters.
[0264] For example, access network devices can collaboratively optimize transmission performance based on CSI reporting information from terminal devices. For instance, when the CQI is low or the channel quality is poor, the transmit power of the first SSB and / or the second SSB is increased to add redundant bits; when the CQI is high or the channel quality is good, the transmit power of the first SSB and / or the second SSB is reduced to improve the transmission rate.
[0265] The rate matching parameter is related to the TBS and / or the modulation and coding scheme (MCS). Optionally, the TBS is related to one or more of the following parameters of the first SSB: period, number of symbols used in the transmission, or number of subcarriers used in the transmission.
[0266] For example, the time interval between Scell activation and the actual reception of the first SSB by the terminal device represents the number of time slots in a subframe. The access network device dynamically adjusts the number of time slots in the subframe based on channel quality reporting information (e.g., CSI report) to achieve optimal rate matching.
[0267] For example, the period of the first SSB varies with the number of symbols and subcarriers configured for each SSB burst in the first configuration information. Optimal rate matching is achieved by changing the period of the first SSBB, or by changing the number of symbols (or beams) or subcarriers used for transmission. Specifically, the number of symbols or subcarriers used for transmission must be greater than or equal to the minimum number of symbols or subcarriers required by the protocol for the first SSB.
[0268] For example, optimal rate matching can be achieved by changing the period of the first SSB and the second SSB, or by changing the number of symbols or subcarriers occupied by the first SSB burst and / or the second SSB burst. Specifically, the number of symbols or subcarriers occupied by the first SSB and the second SSB must be greater than or equal to the minimum number of symbols or subcarriers specified in the protocol. When the first SSB burst and the second SSB burst conflict in the time domain, their minimum number of symbols must be less than or equal to the sum of the number of symbols occupied by one first burst and the number of symbols occupied by one second SSB burst.
[0269] It should be noted that the solutions related to the impact of HARQ and rate matching, and power control and rate matching on the first SSB transmission parameter configuration and transmission process can all be considered as independent solutions.
[0270] Furthermore, when combining the above methods with rate matching, or considering rate matching alone to resolve conflicts or interference, it is necessary to consider whether rate matching or its behavior is applicable to different scenarios. For example, rate matching can be used after SCell configuration but before activation; or, rate matching can be considered after Instants A but before the first SSB deactivation. No limitations are set here.
[0271] Figure 9 is a schematic diagram of an example of the communication method provided in this application embodiment. This method can be applied to the communication system shown in Figure 6, and is illustrated using the interaction between an access network device and a terminal device as an example. Of course, the entity executing the action of the access network device in this method can also be a device / module in the access network device, such as a chip, processor, or processing unit in the access network device; the entity executing the action of the terminal device in this method can also be a device / module in the terminal device, such as a chip, processor, or processing unit in the terminal device. This application embodiment does not specifically limit this. In this application embodiment, the processing performed by a single executing entity (e.g., the processing performed by the access network device and the terminal device) can also be divided into multiple executing entities, which can be logically and / or physically separated. For example, as shown in Figure 9, taking the terminal device access network device as an example, method 900 includes the following steps:
[0272] In S910, the access network device sends the first signaling message to the terminal device. Correspondingly, the terminal device receives the first signaling message from the access network device.
[0273] In this embodiment of the application, the first signaling can be one or more of the following: a first DCI, or a DCI with the same format as the first DCI.
[0274] In this embodiment of the application, the first DCI is used to indicate the activation or deactivation of DTX, and / or the activation or deactivation of DRX.
[0275] Among them, the DCI with the same format as the first DCI can be the second DCI, or the third DCI.
[0276] In this embodiment, the second DCI is used to indicate SSB adjustment information, and the third DCI is used to trigger the first SSB. The first SSB is an on-demand SSB, and its description can be found in the description of OD SSB in related technical documents; this embodiment will not repeat it here. Of course, the first SSB can also have other names, and this embodiment does not limit this. The second DCI indicating SSB adjustment information can also be described as parameters used to indicate adjustment (or switching, updating, activating) of the SSB or parameters used to determine the SSB. SSB parameters can be the SSB burst period or other parameters (other parameters can be found in the SSB parameters described in the prior art); this embodiment does not limit this. In some descriptions of this embodiment, the SSB parameters are described using the SSB burst period as an example. The third DCI triggering the first SSB can be described as indicating the transmission of the first SSB or activating the first SSB.
[0277] In this embodiment of the application, the format of the first DCI is the first format, which can be DCI format 2_9, or other formats. This embodiment of the application does not limit this.
[0278] The DCI information bits of the first format are divided into N blocks (block#1, block#2, ..., block#N). Each block consists of n bits (n is greater than or equal to 0), and each block is associated with one or more secondary cells or with one serving cell.
[0279] It should be noted that in one possible implementation, the DCI with the same format as the first DCI is the second DCI; in another possible implementation, the DCI with the same format as the first DCI is the third DCI.
[0280] For example, the access network device can configure a search space set of the first format on different cells. Specifically, the access network device configures a search space set of the first format on the first cell, which is used to listen to the first DCI, and the access network device configures a search space set of the first format on the second cell, which is used to listen to the second DCI.
[0281] In this embodiment, for the second DCI, one block can be associated with one or more secondary cells (Scells). The access network device can configure the starting bit position of the terminal device in the second DCI through parameters, which can also be considered as the access network device indicating the starting bit position of the block corresponding to the terminal device in the second DCI. This parameter can be configured according to the cell or according to the cell group, where configuring according to the cell group means that one or more cells correspond to the same block. When the terminal device is configured with multiple secondary cells, the terminal device can have one or more of this parameter, that is, different secondary cells of the terminal device correspond to different blocks. It should be noted that the parameter of different secondary cells can also be the same or different, and this embodiment does not limit this.
[0282] It should be noted that, except for method five, the RNTI of the second DCI and the RNTI of the first DCI may be the same or different, and this application embodiment does not limit this.
[0283] Optionally, the access network device may also configure other parameters of the second DCI, including at least one of the following: the size of the second DCI (number of bits, payload size), RNTI, which are not limited in this embodiment.
[0284] For example, the access network device can configure a search space set of the first format on different cells. Specifically, the access network device configures a search space set of the first format on the first cell, which is used to listen to the first DCI, and the access network device configures a search space set of the first format on the second cell, which is used to listen to the third DCI.
[0285] In this embodiment, for the third DCI, one block can be associated with one or more secondary cells (Scells). The access network device can configure the starting bit position of the terminal device in the third DCI through parameters, which can also be considered as the access network device indicating the starting bit position of the block corresponding to the terminal device in the third DCI. This parameter can be configured according to the cell or according to the cell group, where configuration according to the cell group means that one or more cells correspond to the same block. When the terminal device is configured with multiple secondary cells, the terminal device can have one or more of this parameter, that is, different secondary cells of the terminal device correspond to different blocks. It should be noted that the parameter of different secondary cells can also be the same or different, and this embodiment does not limit this.
[0286] It should be noted that, except for method five, the RNTI of the third DCI and the RNTI of the first DCI may be the same or different, and the embodiments of this application do not limit this.
[0287] Optionally, the access network device may also configure other parameters of the third DCI, including at least one of the following: the size of the third DCI (number of bits, payload size), RNTI, which are not limited in this embodiment.
[0288] The two possible implementation methods will be described in detail below.
[0289] When a DCI with the same format as the first DCI is considered the second DCI, there are several ways to distinguish between the first DCI and the second DCI.
[0290] Method 1: Differentiate by different residential communities.
[0291] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, including: the access network device sending the first DCI to the terminal device in the first cell. Correspondingly, the terminal device receives the first DCI from the access network device in the first cell. The first DCI is used to indicate the activation or deactivation of DTX and / or DRX in one or more cells.
[0292] The second DCI is used to indicate SSB adjustment information, including: the access network device sending the second DCI to the terminal device in the second cell. Correspondingly, the terminal device receives the second DCI from the access network device in the second cell. The second DCI is used to indicate SSB adjustment information for one or more cells.
[0293] The first and second communities are different communities.
[0294] In one possible implementation, the information bits of the second DCI consist of one or more blocks, wherein at least one of the blocks includes a first field for carrying adjustment information of the SSB.
[0295] Optionally, at least one block of the information bits of the second DCI mentioned above further includes a second field and / or a fourth field, wherein the second field is used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field is used to carry an NES mode indication.
[0296] When the second DCI is sent through the second cell, the second field and / or the fourth field are reserved fields, meaning the terminal device ignores the indication information of the second field and / or the fourth field.
[0297] In another possible implementation, the information bits of the second DCI consist of one or more blocks, wherein at least one of the blocks includes a second field and / or a fourth field, the second field being used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field being used to carry an NES mode indication.
[0298] Among them, when the second DCI is sent through the second cell, the second field and / or the fourth field are used to indicate the adjustment information of the SSB.
[0299] In one possible implementation, the information bits of the first DCI consist of one or more blocks. At least one block of the first DCI's information bits includes a second field and / or a fourth field. The second field carries at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX. The fourth field carries an NES mode indication. At least one block of the first DCI's information bits also includes a first field, which carries SSB adjustment information.
[0300] In this embodiment, when the first DCI is transmitted through the first cell, the first field is a reserved field, meaning the terminal device ignores the indication information of the first field. It should be noted that the first cell and the second cell can be a primary cell or a secondary cell. For example, the second cell can be the primary cell, meaning the second DCI is transmitted through the primary cell; the first cell can be one of one or more secondary cells, meaning the first DCI is transmitted through a secondary cell; or the first cell can be the primary cell, and the second cell can be a cell other than the primary cell; or the first cell can be secondary cell 1, and the second cell can be secondary cell 2. This embodiment does not limit the specific cell types. The first cell and the second cell can be within the same cell group.
[0301] Method 2: Differentiate by using different search spaces.
[0302] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, including: the access network device sending the first DCI to the terminal device during a PDCCH listening session in the first search space set. Correspondingly, the terminal device receives the first DCI from the access network device during a PDCCH listening session in the first search space. The first DCI is used to indicate the activation or deactivation of DTX and / or DRX in one or more cells.
[0303] The second DCI is used to indicate SSB adjustment information, including: the access network device sending the second DCI to the terminal device during the PDCCH listening time of the second search space set. Correspondingly, the terminal device receives the second DCI from the access network device during the PDCCH listening time of the second search space. The second DCI is used to indicate SSB adjustment information for one or more cells.
[0304] The first search space set and the second search space set are different search space sets.
[0305] In one possible implementation, the information bits of the second DCI consist of one or more blocks, wherein at least one of the blocks includes a first field for carrying adjustment information of the SSB.
[0306] Optionally, at least one block of the information bits of the second DCI mentioned above further includes a second field and / or a fourth field, wherein the second field is used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field is used to carry an NES mode indication.
[0307] Wherein, when the second DCI is sent through the PDCCH listening time of the second search space set, the second field and / or the fourth field are reserved fields, that is, the terminal device ignores the indication information of the second field and / or the fourth field.
[0308] In another possible implementation, the information bits of the second DCI consist of one or more blocks, wherein at least one of the blocks includes a second field and / or a fourth field, the second field being used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field being used to carry an NES mode indication.
[0309] Among them, when the second DCI is sent through the PDCCH listening time of the second search space set, the second field and / or the fourth field are used to indicate the adjustment information of the SSB.
[0310] In one possible implementation, the information bits of the first DCI consist of one or more blocks. At least one block of the first DCI information bits includes a second field and / or a fourth field. The second field carries at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX. The fourth field carries an NES mode indication. At least one block of the first DCI information bits also includes a first field, which carries SSB adjustment information. When the first DCI is transmitted through a first search space set, the first field is a reserved field, meaning the terminal device ignores the indication information in the first field.
[0311] It should be noted that the first search space set and the second search space set can be configured on the same cell or different cells. When the first search space set and the second search space set are configured on different cells, the implementation methods of Method 2 and Method 1 are equivalent.
[0312] Method 3: Differentiate by using different time-domain resources.
[0313] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, including: the access network device sending the first DCI to the terminal device in the first time domain resource. Correspondingly, the terminal device receives the first DCI from the access network device in the first time domain resource. The first DCI is used to indicate the activation or deactivation of DTX and / or DRX of one or more cells.
[0314] The second DCI is used to indicate SSB adjustment information, including: the access network device sending the second DCI to the terminal device in the second time domain resources. Correspondingly, the terminal device receives the second DCI from the access network device in the second time domain resources. The second DCI is used to indicate SSB adjustment information for one or more cells.
[0315] The first time-domain resource and the second time-domain resource are different time-domain resources. The first time-domain resource and the second time-domain resource can be in different time periods.
[0316] For example, the first time domain resource is located after the secondary cell is activated, and the second time domain resource is located before the secondary cell is activated.
[0317] For example, "before the secondary cell is activated" includes: the secondary cell being configured but not yet receiving an activation command; receiving an activation command; or receiving an activation command until the secondary cell is fully activated. "After the secondary cell is activated" includes: after the secondary cell is fully activated.
[0318] In one possible implementation, the information bits of the second DCI consist of one or more blocks, wherein at least one of the blocks includes a first field for carrying adjustment information of the SSB.
[0319] Optionally, at least one block of the information bits of the second DCI also includes a second field and / or a fourth field, wherein the second field is used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field is used to carry an NES mode indication.
[0320] Wherein, when the second DCI is sent through the second time domain resource, the second domain and / or the fourth domain are reserved domains, that is, the terminal device ignores the indication information of the second domain and / or the fourth domain.

[0327] In this implementation, in some cases, the second field and / or the fourth field are reserved, meaning the terminal device ignores the indications for the second field and / or the fourth field. For example, before the Scell completes activation, the terminal device ignores the indications for the second field and / or the fourth field for that Scell.
[0328] Method 5: Differentiate by using different RNTIs.
[0329] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, and includes: the access network device sending a first DCI scrambled with a first RNTI to the terminal device. Correspondingly, the terminal device receives the first DCI scrambled with a first RNTI from the access network device.

[0337] For cases where the format is the same as the first DCI but is the third DCI, there are several ways to distinguish between the first DCI and the third DCI.

At least one block of the first DCI information bits also includes a third field, which carries a trigger indication for the first SSB.
[0348] In this embodiment, when the first DCI is transmitted through the first cell, the third field is a reserved field, meaning the terminal device ignores the indication information in the third field. It should be noted that the first cell and the third cell can be a primary cell or a secondary cell. For example, the third cell can be the primary cell, meaning the third DCI is transmitted through the primary cell; the first cell can be one of one or more secondary cells, meaning the first DCI is transmitted through a secondary cell; or the first cell can be the primary cell, and the third cell can be a cell other than the primary cell; or the first cell can be secondary cell 1, and the third cell can be secondary cell 2. This embodiment does not limit this. The first cell and the second cell can be within the same cell group.
[0349] Method 2: Differentiate by using different search space sets.
[0350] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, and includes: the access network device sending the first DCI to the terminal device during a PDCCH listening session of the first search space set. Correspondingly, the terminal device receives the first DCI from the access network device during a PDCCH listening session of the first search space set.

[0355] Among them, when the third DCI is sent through the PDCCH listening time of the third search space set, the second field and / or the fourth field are reserved fields, that is, the terminal device ignores the indication information of the second field and / or the fourth field.

[0357] Among them, when the third DCI is sent through the PDCCH listening time of the third search space set, the second field and / or the fourth field are used to trigger the first SSB.
[0358] In one possible implementation, the information bits of the first DCI consist of one or more blocks. At least one block of the first DCI information bits includes a second field and / or a fourth field. The second field carries at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX. The fourth field carries an NES mode indication. At least one block of the first DCI information bits also includes a third field, which carries a trigger indication for the first SSB. When the first DCI is sent through the first search space set, the third field is a reserved field, meaning the terminal device ignores the indication information in the third field.
[0359] It should be noted that the first search space set and the third search space set can be configured on the same cell or different cells. When the first search space set and the third search space set are configured on different cells, the implementation methods of Method 2 and Method 1 are equivalent.
[0360] Method 3: Differentiate by using different time-domain resources.
[0361] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, including: the access network device sending the first DCI to the terminal device in the first time domain resource. Correspondingly, the terminal device receives the first DCI from the access network device in the first time domain resource.

[0362] The third DCI is used to trigger the first SSB, including: the access network device sending the third DCI to the terminal device in the third time domain resources. Correspondingly, the terminal device receives the third DCI from the access network device in the third time domain resources. The third DCI is used to trigger the first SSB of one or more cells.
[0363] The first time domain resource and the third time domain resource are different time domain resources. The first time domain resource and the third time domain resource can be in different time periods. For example, the first time domain resource is located after the secondary cell is activated, and the third time domain resource is located before the secondary cell is activated.
[0364] For example, "before the secondary cell is activated" includes: the secondary cell being configured but not yet receiving an activation command; receiving an activation command; or receiving an activation command until the secondary cell is fully activated. "After the secondary cell is activated" includes: after the secondary cell is fully activated.
[0365] In one possible implementation, the information bits of the third DCI consist of one or more blocks, wherein at least one of the blocks includes a third field for carrying a trigger indication of the first SSB.

Wherein, when the first DCI is transmitted using the first time domain resource, the third field is a reserved field, meaning the terminal device ignores the indication information in the third field.
[0371] Method 4: Differentiate by different domains in the first DCI
[0372] In this implementation, the DCI can be either the first DCI or the third DCI.
[0373] In this manner, the information bits of the first DCI consist of one or more blocks, wherein at least one of the one or more blocks includes: a second field, and / or a fourth field, the second field, and / or the fourth field being used to carry at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, the fourth field being used to carry an NES mode indication; and a third field, the third field being used to carry a trigger indication of the first SSB.
[0374] In this implementation, in some cases, the second field and / or the fourth field are reserved, meaning the terminal device ignores the indications for the second field and / or the fourth field. For example, before the Scell completes activation, the terminal device ignores the indications for the second field and / or the fourth field for that Scell.
[0375] Method 5: Differentiate by using different RNTIs.
[0376] The first DCI is used to indicate the activation or deactivation of DTX and / or DRX, and includes: the access network device sending a first DCI scrambled with a first RNTI to the terminal device. Correspondingly, the terminal device receives the first DCI scrambled with a first RNTI from the access network device.

[0377] The third DCI is used to trigger the first SSB, including: the access network device sending a third DCI scrambled with a third RNTI to the terminal device.

[0381] Among them, when the third DCI is scrambled by the third RNTI, the second field and / or the fourth field are reserved fields.
[0382] In another possible implementation, the information bits of the third DCI consist of one or more blocks, wherein at least one of the blocks includes a second field and / or a fourth field, the second field being used to indicate at least one of the following: activation or deactivation of DTX, and / or activation or deactivation of DRX, and the fourth field being used to carry an NES mode indication.
[0383] Among them, when the third DCI is scrambled by the third RNTI, the second domain and / or the fourth domain are used to trigger the first SSB.
[0384] S920, the terminal device performs an operation according to the instructions of the first signaling.
[0385] In this embodiment of the application, the terminal device performs an operation according to the instruction of the first signaling, including: the terminal device performing the operation of activating or deactivating DTX, and / or activating or deactivating DRX; the terminal device receiving an SSB according to the adjusted SSB parameters indicated by the DCI; or, the terminal device receiving a first SSB. Correspondingly, the access network device performs the operation of activating or deactivating DTX, and / or activating or deactivating DRX; the access network device sends an SSB according to the adjusted SSB parameters indicated by the DCI; or, the access network device sends a first SSB.
[0386] The method provided in this application embodiment enables the access network device and the terminal device to distinguish the functions of the first format through at least one of the above methods. Furthermore, in some implementations, the access network device and / or the terminal device may ignore the indication of some functions (e.g., activation or deactivation of DTX, and / or activation or deactivation of DRX, NES mode indication).
[0387] Optionally, the communication method provided in this application embodiment further includes:
[0388] In step S930, the access network device sends a first indication message to the terminal device. Correspondingly, the terminal device receives the first indication message from the access network device.
[0389] It should be noted that step S930 can be located before step S920 or step S910.
[0390] It should be noted that the first instruction information may be included in the first signaling, that is, the first instruction information and the first signaling are the same message. Alternatively, the first instruction information and the first signaling may be different messages.
[0391] In this embodiment of the application, the first indication information is used to indicate the time domain offset between the first time and the second time.
[0392] The first moment refers to the moment when the terminal device receives the first control signaling. The first control signaling is used to trigger the first SSB, or it is used to indicate the adjustment information of the SSB. The first moment can be the start time unit or the end time unit of the first control signaling.
[0393] For example, the terminal device receives a first control signaling at a first moment (e.g., slot n), which is used to indicate SSB adjustment information or trigger a first SSB. The terminal device receives the SSB no earlier than instance A according to the adjusted parameters (e.g., period) or no earlier than instance A, where instance A is the second moment (e.g., it can be represented as slot n+m). Correspondingly, the access network device sends the SSB no earlier than instance A according to the adjusted parameters (e.g., period) or no earlier than instance A. For example, the terminal device receives the SSB according to the adjusted parameters (e.g., period) or the first SSB according to the parameters of the first SSB starting from instance A.
[0394] The first control signaling can be either the second DCI or the third DCI mentioned above.
[0395] Alternatively, as one possible implementation, the time-domain offset between the first and second time points is predefined.
[0396] In this embodiment of the application, the time domain offset between the first time and the second time is related to one or more of the following: the subcarrier spacing of the first control signaling, the subcarrier spacing of the SSB before adjustment, the subcarrier spacing of the SSB after adjustment, or the subcarrier spacing of the first SSB.
[0397] For example, the time-domain offset differs with different subcarrier spacings.
[0398] Optionally, the time-domain offset between the first time point and the second time point is also related to one or more of the following:
[0399] The number of activated or configured secondary cells, the number of secondary cells that trigger the first SSB simultaneously as indicated by the first control signaling, the number of secondary cells that adjust SSB parameters simultaneously as indicated by the first control signaling, the time at which the terminal device sends feedback information of the first control signaling, or the function indicated by the first control signaling, the function of the first control signaling includes: the first control signaling instructs the triggering of the first SSB, or the first control signaling instructs SSB adjustment information.
[0400] The feedback information can be HARQ-ACK feedback, but this application embodiment does not limit this.
[0401] For example, the more secondary cells that are activated or configured, the more secondary cells that trigger the first SSB at the same time as the first control signaling indication, or the more secondary cells that adjust the SSB parameters at the same time as the first control signaling indication, the larger the time domain offset.
[0402] In this embodiment of the application, the time domain offset between the first time point and the second time point includes one or more of the following:
[0403] The time when the terminal device parses the first control signaling, the time when the access network device and / or the terminal device adjusts the SSB parameters, the time when the access network device prepares to send the first SSB, or the time when the terminal device prepares to receive the first SSB.
[0404] It should be noted that the content of the first control signaling indication can differ, and the time domain offset between the first and second time points can also be different. For example, the time domain offset corresponding to the first control signaling indication of adjusting SSB parameters and indicating the triggering of the first SSB can be different. The time domain offset corresponding to the first control signaling indication of adjusting SSB parameters and indicating DTX activation / deactivation can be the same or different. The time domain offset corresponding to the first control signaling indication of triggering the first SSB and indicating DTX activation / deactivation can be the same or different. The time domain offset corresponding to the first control signaling indication of adjusting SSB parameters and indicating DRX activation / deactivation can be the same or different. The time domain offset corresponding to the first control signaling indication of triggering the first SSB and indicating DRX activation / deactivation can be the same or different.
[0405] Taking the first control signaling instruction to adjust SSB parameters or trigger the first SSB as an example, which corresponds to the same time domain offset as the DRX activation / deactivation instruction, the time domain offset between the first time and the second time is shown in Table 1 below.
[0406] Table 1
[0407] Optionally, in S940, the terminal device determines the time domain offset between the first time and the second time based on the first instruction information.
[0408] It should be noted that steps S930 and S940 can form an independent scheme. The implementation method of the first control signaling in steps S930 and S940 is not limited to the implementation method of the first signaling in S910.
