[0057] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0058] The communication system scenario includes a terrestrial network (TN) and an NTN. Among them, the NTN generally adopts a satellite communication mode to provide communication services to ground users. The NTN system currently includes an NR-NTN and an IoT-NTN system, and may further include other NTN systems in the future.

[0059] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. As shown in FIG. 1, the communication system 100 can include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 through an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0060] It should be understood that the embodiments of the present application are only exemplarily described with respect to the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a long term evolution (LTE) system, an LTE time division duplex (TDD), a universal mobile telecommunication system (UMTS), an internet of things (IoT) system, a narrow band internet of things (NB-IoT) system, an enhanced machine type communication (eMTC) system, a 5G communication system (also referred to as a new radio (NR) communication system), or a future communication system, etc.

[0061] In the communication system 100 shown in FIG. 1, the network device 120 can be an access network device that communicates with the terminal device 110. The access network device can provide communication coverage for a specific geographic area, and can communicate with the terminal device 110 (such as a UE) located in the coverage area.

[0062] The network device 120 can be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in a NR system, or a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0063] The terminal device 110 can be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0064] For example, the terminal device 110 can refer to an access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user equipment. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handset, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved network, etc.

[0065] The terminal device 110 can be used for Device to Device (D2D) communication.

[0066] The wireless communication system 100 can further include a core network device 130 in communication with the base station, which can be a 5G core network (5GC) device, e.g., an Access and Mobility Management Function (AMF), e.g., an Authentication Server Function (AUSF), e.g., a User Plane Function (UPF), e.g., a Session Management Function (SMF). Alternatively, the core network device 130 can also be an Evolved Packet Core (EPC) device of an LTE network, e.g., a Session Management Function + Core Packet Gateway (SMF + PGW-C) device. It should be understood that the SMF + PGW-C can implement the functions of both the SMF and the PGW-C. In the process of network evolution, the above-mentioned core network device can also be called by other names, or new network entities can be formed by dividing the functions of the core network, which is not limited by the embodiments of the present application.

[0067] The various functional units in the communication system 100 can also establish connections through a next generation (NG) interface to communicate with each other.

[0068] For example, the terminal device establishes an air interface connection with the access network device through the Uu interface, which is used to transmit user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (N1 for short); the access network device, e.g., a next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (N3 for short); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (N2 for short); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (N4 for short); the UPF can interact with the data network to transmit user plane data through the NG interface 6 (N6 for short); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (N11 for short); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (N7 for short).

[0069] Fig. 1 shows an example of a base station, a core network device and two terminal devices. Optionally, the wireless communication system 100 can include multiple base station devices and each base station can include other numbers of terminal devices within its coverage, which are not limited in the embodiments of the present application.

[0070] NTN generally provides communication services to ground users in the way of satellite communication. Compared with ground cellular network communication, satellite communication has many unique advantages. First, satellite communication is not limited by the user's region. For example, general land communication cannot cover oceans, high mountains, deserts and other areas where communication equipment cannot be set up or communication coverage cannot be provided due to sparsely populated areas. However, for satellite communication, since a satellite can cover a large ground, and the satellite can orbit around the earth, theoretically every corner of the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor countries or regions at a low cost, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting the development of these areas. Third, satellite communication is far away, and the cost of communication does not increase significantly as the communication distance increases. Finally, satellite communication has high stability and is not limited by natural disasters.

[0071] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with an NR system to form an NR-NTN system. For another example, NTN technology can be combined with an Internet of Things (IoT) system to form an IoT-NTN system. As an example, the IoT-NTN system can include an NB-IoT-NTN system and an eMTC-NTN system.

[0072] Fig. 2 is a schematic diagram of another architecture of a communication system according to an embodiment of the present application.

[0073] As shown in Fig. 2, the communication system includes a terminal device 1101 and a satellite 1102, and the terminal device 1101 and the satellite 1102 can perform wireless communication. The network formed between the terminal device 1101 and the satellite 1102 can also be referred to as NTN. In the architecture of the communication system shown in Fig. 2, the satellite 1102 can have the function of a base station, and the terminal device 1101 and the satellite 1102 can directly communicate with each other. In the system architecture, the satellite 1102 can be referred to as a network device. In some embodiments of the present application, multiple network devices 1102 can be included in the communication system, and each network device 1102 can include other numbers of terminal devices within its coverage, which are not limited in the embodiments of the present application.

[0074] Fig. 3 is a schematic diagram of another architecture of a communication system according to an embodiment of the present application.

[0075] As shown in FIG. 3, a communication system includes a terminal device 1201, a satellite 1202, and a base station 1203. The terminal device 1201 and the satellite 1202 can communicate with each other wirelessly, and the satellite 1202 can communicate with the base station 1203. The network formed by the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG. 3, the satellite 1202 can not have the function of a base station, and communication between the terminal device 1201 and the base station 1203 needs to be relayed by the satellite 1202. In this kind of system architecture, the base station 1203 can be referred to as a network device. In some embodiments of the present application, multiple network devices 1203 can be included in the communication system, and each network device 1203 can include a number of terminal devices within its coverage range, which is not limited in the embodiments of the present application. The network device 1203 can be the network device 120 in FIG. 1.

[0076] It should be understood that the satellite 1102 or the satellite 1202 described above includes but is not limited to:

[0077] Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, and the like. Satellites can use multiple beams to cover the ground, for example, a satellite can form tens or even hundreds of beams to cover the ground. In other words, a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers to ensure the coverage of the satellite and improve the system capacity of the entire satellite communication system.

[0078] By way of example, the altitude range of a LEO satellite can be 500 kilometers to 1500 kilometers, and the corresponding orbit period can be about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users can generally be less than 20 milliseconds, and the maximum satellite visibility time can be 20 minutes. The signal propagation distance of a LEO satellite is short and the link loss is small, and the transmit power requirement of the user terminal is not high. The orbit altitude of a GEO satellite can be 35786 km, and the rotation period around the earth can be 24 hours. The signal propagation delay of single-hop communication between users can generally be 250 milliseconds.

[0079] In order to ensure the coverage of the satellite and improve the system capacity of the entire satellite communication system, the satellite uses multiple beams to cover the ground, and a satellite can form tens or even hundreds of beams to cover the ground. A satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0080] It should be noted that FIG. 1 to FIG. 3 only schematically show the system to which the embodiments of the present application are applied in an exemplary manner. Of course, the method shown in the embodiments of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in the present application. The term "and / or" in the present application is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the front and rear associated objects. It should also be understood that the "indication" mentioned in the embodiments of the present application can be direct indication or indirect indication, and can also represent an associated relationship. For example, A indicates B, which can mean that B can be obtained through A; or A indirectly indicates B, for example, A indicates C, and B can be obtained through C; or A and B have an associated relationship. It should also be understood that the "corresponding" mentioned in the embodiments of the present application can represent a direct correspondence or an indirect correspondence between the two, or can represent an associated relationship between the two, or can represent an indication and being indicated, configuration and being configured, and the like. It should also be understood that the "predefined" or "predefined rule" mentioned in the embodiments of the present application can be realized by pre-saving the corresponding code, table or other means that can be used to indicate related information in the device (for example, including terminal device and network device), and the specific implementation manner of the present application is not limited. For example, the predefinition can refer to the definition in the protocol. It should also be understood that the "protocol" in the embodiments of the present application can refer to the standard protocol in the communication field, for example, it can include the LTE protocol, the NR protocol and the related protocol applied to the future communication system, and the present application is not limited thereto.

[0081] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any manner, and all belong to the protection scope of the embodiments of the present application.

[0082] Physical downlink control channel (PDCCH) monitoring for paging early indication (PEI)

[0083] In the NR system, the terminal device in the radio resource control (RRC) idle state and the RRC inactive state can use PEI to reduce power consumption. If the PEI configuration is provided in the system message, the terminal device in the RRC idle state or the RRC inactive state can monitor the PEI according to the following flow:

[0084] A terminal device monitors a paging early indication occasion (PEI-O) in each DRX cycle. A PEI-O is a set of PDCCH monitoring occasions, which can contain multiple time units (e.g., subframes or Orthogonal Frequency Division Multiplexing (OFDM) symbols) for transmitting a PEI. A PEI-O can be associated with one or two POs in a paging frame (PF), and the maximum number of PFs associated with a PEI-O is 2.

[0085] The time-domain location of a PEI-O is determined by a reference time point and an offset value:

[0086] The reference time point is the start of a reference frame determined by frame-level offset from the start of the first PF associated with the PEI-O;

[0087] The offset value is the symbol-level offset between the start of the first PDCCH monitoring occasion of the PEI-O and the reference time point.

[0088] A PEI-O is a set of S consecutive PDCCH monitoring occasions, where S is the actual number of transmitted SS / PBCH Blocks (SSBs), and the Kth PDCCH monitoring occasion for PEI in the PEI-O corresponds to the Kth transmitted SSB, where K = 1, 2, …, S. In a multi-beam scenario, a terminal device assumes that the same PEI is repeatedly transmitted in all transmitted beams. When a terminal device detects a PEI in a PEI-O, it is not required to monitor the subsequent PDCCH monitoring occasions associated with the same PEI-O.

[0089] A PEI is carried by a Downlink Control Information (DCI) 2_7 with cyclic redundancy check (CRC) scrambled by a PEI-radio network temporary identity (RNTI), and the paging indication field of the DCI 2_7 contains bits, where is the number of terminal device subgroups in each PO, i.e., each bit in the paging indication field indicates a terminal device subgroup in a PO. Specifically, for a terminal device with a subgroup index i SG , the terminal device monitors the PO associated with the i-th bit in the paging indication field. ​​) the value of the bit determines whether to monitor its associated PO, where i PO is associated with the PEI-O The PO index corresponding to the terminal device in the i th PO, when the bit value is '1', the terminal device monitors its associated PO; otherwise, the terminal device is not required to monitor the PO.

[0090] Cell DTX / Cell DRX adaptation

[0091] For the terminal device configured with cell DTX and / or cell DRX on the serving cell, one Type3-PDCCH common search space (CSS) set can be additionally provided by the higher layer parameter to monitor the PDCCH carrying DCI 2_9 in the activation time, where the starting bit position of the bit block associated with the serving cell, i.e. the cell DTX / Cell DRX indication field, is provided by the higher layer parameter:

[0092] If the terminal device is configured with both cell DTX and cell DRX on the serving cell and enables dynamic activation / deactivation of the cell DTX / Cell DRX configuration based on DCI 2_9, the cell DTX / Cell DRX indication field contains 2 bits, where the 1st bit indicates the cell DTX and the 2nd bit indicates the cell DRX;

[0093] If the terminal device is configured with only one of cell DTX and cell DRX on the serving cell and enables dynamic activation / deactivation of the cell DTX / Cell DRX configuration based on DCI 2_9, the cell DTX / Cell DRX indication field contains 1 bit indicating one of the cell DTX and the cell DRX;

[0094] The bit value '0' of the cell DTX / Cell DRX indication field indicates that the cell DTX or the cell DRX is deactivated;

[0095] The bit value '1' of the cell DTX / Cell DRX indication field indicates that the cell DTX or the cell DRX is activated;

[0096] If the serving cell is configured with a supplementary uplink (SUL) carrier, the cell DRX activation or deactivation indicated by the cell DTX / Cell DRX indication field applies to both the uplink (UL) carrier and the SUL carrier;

[0097] If the network energy saving (NES) specific conditional handover (CHO) event is configured, the NES mode indication field contains 1 bit to indicate the NES specific CHO execution condition:

[0098] The NES mode indication field '0' value indicates that the CHO execution condition specific to the NES is not met.

[0099] The NES mode indication field '1' value indicates that the CHO execution condition specific to the NES is met.

[0100] The terminal device does not expect to monitor PDCCH carrying DCI 2_9 on more than one serving cell of one cell group.

[0101] In the related art, considering that the satellite power and the feeder link bandwidth are limited, all satellite beams corresponding to the potential ground service areas under the satellite coverage cannot be turned on at the same time, and the satellite beams need to be jumped to provide services for the potential ground areas. However, the cell DTX / cell DRX mechanism of the NR system is only effective for the terminal device in the RRC connected state, and when the satellite performs the beam hopping function, all channels will be turned off in the non-activated time of the beam. However, based on the cell DTX or the cell DRX, there is still some channel reception and transmission in the non-activated time, which causes the cell DTX or the cell DRX to be unable to support the satellite beam hopping function. Therefore, how to support the satellite beam hopping function through the cell DTX / cell DRX is a problem that needs to be solved urgently.

[0124] In the embodiments of the present application, the configuration information of the cell DTX and / or the cell DRX is provided in the system message, which can enable the terminal device to receive the configuration information of the cell DTX and / or the cell DRX as early as possible, or in other words, enable the terminal device in the RRC idle state, the RRC inactive state and the RRC connected state to apply the configuration of the cell DTX and / or the cell DRX.

[0125] In some embodiments, the first configuration information includes one or more of the following:

[0126] The period of the cell DTX and / or the cell DRX;

[0127] The length of the activation time of the cell DTX and / or the cell DRX;

[0128] The first time, which is the starting time of the activation time of the cell DTX and / or the cell DRX;

[0129] The first indication information, which is used to indicate the activation state of the first configuration information.

[0130] In the embodiments of the present application, the configuration information of the cell DTX and / or the cell DRX contains at least one of the following configuration parameters: the period T of the cell DTX and / or the cell DRX, the length D and the starting time t0 of the activation time of the cell DTX and / or the cell DRX, and the activation state of the configuration information of the cell DTX and / or the cell DRX.

[0133] In an embodiment of the present application, the first indication information is used to indicate the activation state of the first configuration information including the first indication information, i.e., activation or deactivation, i.e., whether to apply the configuration parameters in the first configuration information.

[0134] The first indication information can indicate activation or deactivation based on different values. In an example, the value of the first indication information is 1, indicating activation, and the value of the first indication information is 0, indicating deactivation.

[0135] It can be understood that the first information includes a plurality of first configuration information, and the activation state of one of the plurality of first configuration information is activated or the activation state of all of the first configuration information is deactivated.

[0140] In an embodiment of the present application, if the system message includes one first information, the second indication information can be understood as indicating the cell DTX and / or the cell DRX at the cell level to be activated or deactivated. If the system message includes a plurality of first information, the second indication information can be understood as indicating the cell DTX and / or the cell DRX at the beam level to be activated or deactivated, i.e., different second indication information is used to indicate the activation or deactivation of the cell DTX and / or the cell DRX on different SSB beams.

[0142] In some embodiments, the first information further includes an SSB index, and one or more first configuration information and / or the second indication information in the first information is applied to the SSB beam corresponding to the SSB index.

[0143] In the embodiments of the present application, the first information includes an SSB index, and one or more first configuration information included in the first information is applied to the SSB beam corresponding to the SSB index, that is, the cell DTX and / or the cell DRX at the beam level is configured.

[0144] In an example, the first information 1 is {cell DTX and / or cell DRX configuration parameter #1, SSB index #1}, the first information 2 is {cell DTX and / or cell DRX configuration parameter #2, SSB index #2}, and so on.

[0145] In an example, the first information 1 is {cell DTX and / or cell DRX configuration parameter #1, cell DTX and / or cell DRX configuration parameter #2, SSB index #1}, the first information 2 is {cell DTX and / or cell DRX configuration parameter #3, SSB index #2}.

[0146] It should be noted that when the terminal device supports the satellite beam hopping function, the terminal device activates one of the first configuration information in the first information corresponding to the SSB index of the current SSB beam.

[0147] In the embodiments of the present application, in the NTN scenario, one satellite beam can be one SSB beam, and one cell contains multiple satellite beams, that is, SSB beams. If the cell DTX and / or the cell DRX at the beam level is configured, a more flexible beam hopping mode can be provided.

[0151] S901、The network device sends a first DCI, the first DCI is used to indicate the activation state of cell DTX and / or cell DRX, and / or second configuration information, the second configuration information is the activated first configuration information in the plurality of first configuration information included in the first information.

[0152] In the embodiment of the application, the first DCI can be understood as being used to adjust the cell DTX and / or cell DRX configuration, such as: the activation state of cell DTX and / or cell DRX, the cell DTX and / or cell DRX configuration information.

[0153] The first DCI used to indicate the activation state of cell DTX and / or cell DRX can be understood as the first DCI used to indicate the activation or deactivation of cell DTX and / or cell DRX.

[0154] The first DCI is used to indicate the second configuration information. The second configuration information can be understood as one configuration information in the plurality of activated first configuration information that has been configured, or the cell DTX and / or cell DRX configuration information applied by the terminal device.

[0157] In the embodiment of the application, in the case that the first DCI indicates the second configuration information, it can be considered that the first DCI implicitly indicates the activation of cell DTX and / or cell DRX.

[0158] It can be understood that the first DCI indicates the activation state of cell DTX and / or cell DRX, and / or the second configuration information, which can be for the terminal device. At this time, it is not necessary to pay attention to which SSB beam the terminal device currently applies, no matter in which SSB beam, the activation state of cell DTX and / or cell DRX can be used to indicate the terminal device to activate or deactivate cell DTX and / or cell DRX, in the case that the second DCI indicates the second configuration information, the terminal device applies the second configuration information for transmission and / or reception.

[0159] It can be understood that for one or more first information, the first DCI can respectively indicate the activation state of cell DTX and / or cell DRX, and / or the second configuration information.

[0161] In an example, if the service of the ground area corresponding to the satellite beam is less, the cell DTX and / or cell DRX can be activated by the DCI to release the time-frequency resources for providing services for other ground areas; if the service of the ground area corresponding to the satellite beam is more, the cell DTX and / or cell DRX can be deactivated by the DCI to provide sufficient time-frequency resources for the ground area by always lighting the satellite beam.

[0162] In an example, multiple sets of cell DTX and / or cell DRX configuration information are provided in the system message, corresponding to different cell DTX and / or cell DRX cycles and / or activation time lengths, such as cell DTX and cell DRX configuration information 1-{cycle T1=20ms, activation time length D=10ms}, cell DTX and cell DRX configuration information 2-{cycle T1=160ms, activation time length D=5ms}, and the network device can flexibly indicate the currently applied cell DTX and / or cell DRX configuration information by the first DCI according to the service demand.

[0163] In the embodiments of the application, the cell DTX and / or cell DRX configuration is indicated by the DCI, which can adapt to the service demand on the ground service area corresponding to the satellite beam, and avoid adjusting the cell DTX and / or cell DRX configuration by the system message changing (poor timeliness problem.

[0172] In some embodiments, the first indication field in the first DCI is used to indicate the activation state of the cell DTX and / or the cell DRX, and / or the second configuration information.

[0173] The position of the first indication field in the first DCI is determined based on the second indication field or a higher layer parameter.

[0174] In the embodiments of the present application, the position of the first indication field in the first DCI can be understood as the position of the bits included in the first indication field in the first DCI.

[0175] In some embodiments, for the DCI scrambled with the PEI-RNTI, the second indication field is a paging indication field.

[0176] For the DCI scrambled with the paging-RNTI, the second indication field is a reserved bit field or a short message field.

[0177] Taking the first DCI including a DCI carrying a PEI as an example, the DCI carrying the PEI has a paging indication field with bits, and as a possible implementation manner, for the DCI carrying the PEI, the bit position of the first indication field is located after the paging indication field (such as from the 1st bit) or is provided by a higher layer parameter.

[0178] Taking the first DCI including a paging DCI as an example, the paging DCI has a reserved bit field, and the 4 bits in the short message field are currently reserved bits, and as another possible implementation manner, for the paging DCI, the first indication field is a bit field composed of part of the bits in the reserved bit field or the short message field.

[0179] ​For example, the first indication field indicates the cell DTX / cell DRX indication. The bit position of the first indication field is provided by a higher layer parameter.

[0180] In some embodiments, the first indication field indicates a plurality of third indication information, different third indication information corresponds to different SSB beams in the plurality of SSB beams, and the third indication information is used to indicate the activation state of the cell DTX and / or the cell DRX of the corresponding SSB beam, and / or the second configuration information.

[0181] In an example, the first indication field indicates the activation state of the cell DTX and / or the cell DRX alone, as shown in Table 1.

[0182] Table 1. The first indication field indicates the activation state of the cell DTX and / or the cell DRX alone

[0183] In an example, the first indication field indicates the second configuration information alone, and the second configuration information indicated by the first DCI includes the cell DTX and / or the cell DRX period and the activation time length, as shown in Table 2.

[0184] Table 2. The first indication field indicates the cell DTX and / or the cell DRX period and the activation time length alone

[0185] In an example, the first indication field jointly indicates the activation state of the cell DTX and / or the cell DRX and the second configuration information, and the second configuration information indicated by the first DCI includes the cell DTX and / or the cell DRX period and the activation time length, as shown in Table 3.

[0186] Table 3. The first indication field jointly indicates the activation state of the cell DTX and / or the cell DRX, the period and the activation time length

[0187] In some embodiments, the first indication field indicates a plurality of third indication information, different third indication information corresponds to different SSB beams in the plurality of SSB beams, and the third indication information is used to indicate the activation state of the cell DTX and / or the cell DRX of the corresponding SSB beam, and / or the second configuration information.

[0188] The first DCI can indicate the activation state of the cell DTX and / or the cell DRX and / or the second configuration information based on the third indication information corresponding to each SSB beam. It can be understood that the first indication field independently indicates the activation state of the cell DTX and / or the cell DRX and / or the applied cell DTX and / or cell DRX configuration information for each SSB beam.

[0189] In the embodiments of the present application, for an SSB beam, the second configuration information indicated by the third indication information corresponding to the SSB beam is one of the one or more first configuration information included in the first information corresponding to the SSB beam.

[0190] In an example, the system message provides the first information of the following three beams: SSB beam 1, SSB beam 2 and SSB beam 3, wherein three third indication information are included in the first indication field: indication information 1, indication information 2 and indication information 3, wherein the indication information 1 is used to indicate the activation state of the cell DTX and / or the cell DRX of the SSB beam 1 and / or the second configuration information, the indication information 2 is used to indicate the activation state of the cell DTX and / or the cell DRX of the SSB beam 2 and / or the second configuration information, and the indication information 3 is used to indicate the activation state of the cell DTX and / or the cell DRX of the SSB beam 1 and / or the second configuration information. Wherein, if the indication information 1 indicates the second configuration information, one of the one or more first configuration information included in the first information corresponding to the SSB beam 1 is included in the first information corresponding to the SSB beam 1; if the indication information 2 indicates the second configuration information, one of the one or more first configuration information included in the first information corresponding to the SSB beam 2 is included in the first information corresponding to the SSB beam 2, and if the indication information 3 indicates the second configuration information, one of the one or more first configuration information included in the first information corresponding to the SSB beam 3 is included in the first information corresponding to the SSB beam 3.

[0191] In an example, 4 SSB beams are transmitted in a cell, and the first indication field contains 4 bits to indicate the cell DTX and / or the cell DRX activation state of each SSB beam.

[0192] In an example, 3 sets of cell DTX / cell DRX configuration information are provided in the system message, and the first indication field contains 8 bits, and each 2 bits is used to indicate the cell DTX / cell DRX configuration information applied by one SSB beam, so that different satellite beams of the same cell can be switched in a more independent and flexible manner.

[0193] In some embodiments, the wireless communication method provided by the embodiments of the present application is applied to a terminal device, as shown in FIG. 10, which includes the following steps:

[0194] S1001, the terminal device determines a second time, the second time being the starting moment of the actual cell DRX activation time;

[0195] The second time is determined based on a third time, the third time being the starting moment of the cell DRX activation time and / or the starting moment of the cell DTX activation time in the third configuration information, and the third configuration information including the activated cell DRX configuration information and / or the activated cell DTX configuration information in the one or more first information.

[0196] The third time can be a start time t0 of a cell DRX active time indicated by current cell DRX configuration information. The start time t0 of the cell DRX active time indicated by the current cell DRX configuration information can also be the start time of a cell DTX active time. The active cell DRX and / or cell DTX configuration information, i.e., the third configuration information, can be active first configuration information provided by a system message or second configuration information indicated by the first DCI.

[0197] In some embodiments, there is a first offset value Δ1 between the start time of the actual cell DRX active time, i.e., the second time, and the start time of the configured cell DRX active time, i.e., the third time, i.e., the cell DRX active time is started at time t, where (t-Δ1) mod(T) = (t0).

[0198] In an example, as shown in FIG. 11, the network device configures the start time of the cell DTX and cell DRX active time as t0, and the start time of the actual cell DRX active time, i.e., the second time, is t1 = t0+Δ1, where Δ1 is an offset value existing in the uplink and downlink timing on the satellite side, i.e., the first offset value.

[0199] In an NTN system, before the terminal device sends uplink, it performs timing advance (TA) adjustment based on downlink timing, and the adjustment value is N TA is a closed-loop TA adjustment value, N TA,offset is a TA offset value, is a service link TA determined by the terminal device using the satellite position and its own position, is a TA between the uplink time synchronization reference point and the serving satellite determined by the terminal device based on the common TA parameter, where the uplink time synchronization reference point is the position of the terminal device considering the TA offset value N TA,offset after the uplink and downlink frame alignment position.

[0200] In an example, as shown in FIG. 12, assuming N TA = 0, N TA,offset = 0, when the reference point is located at the satellite, At this time, the terminal device determines After TA adjustment, the uplink signal can be ensured to be aligned with the downlink timing when reaching the satellite (i.e., the uplink time synchronization reference point). Further, if the activation time of the cell DTX and the cell DRX is configured to correspond to the same timing index (i.e., the activation time length D and the starting time t0 are both the same), and the satellite turns on the satellite beam during the activation time of the cell DTX and the cell DRX, the activation time of the cell DTX and the cell DRX on the satellite side can be ensured to be aligned with the turning-on time of the satellite beam. Thus, the satellite beam hopping function is supported by the cell DTX and the cell DRX.

[0201] In an example, as shown in FIG. 13, when the uplink time synchronization reference point is not located at the satellite, Even if the activation time of the cell DTX and the cell DRX is configured to correspond to the same timing index, the actual activation time of the cell DTX and the cell DRX is not aligned on the satellite side, such as a difference of At this time, how to turn on the satellite beam based on the activation time of the cell DTX and the cell DRX needs to be considered.

[0202] In the embodiments of the present application, the starting time t0 of the activation time of the cell DTX and / or the cell DRX configured by the network device is adjusted based on the offset value of the uplink and downlink timing on the satellite side, which can ensure that the starting time of the activation time of the cell DTX and the cell DRX on the satellite side is the same. Based on this, the satellite beam is turned on during the actual activation time of the cell DTX and the cell DRX, thereby supporting the satellite beam hopping function.

[0203] In some embodiments, the second time is determined based on the third time and a first offset value, and the first offset value is determined based on one or more of the following parameters: a timing advance (TA) offset value; a closed loop TA; a common TA.

[0204] In the embodiments of the present application, the terminal device determines the first offset value Δ1 based on at least one of the following: a TA offset value (N TA,offset ), a closed loop TA (N TA ), and a common

[0205] In an example, as shown in FIG. 14, the network device configures the starting time t0 of the activation time of the cell DTX and the cell DRX, and if the uplink and downlink timing offset value on the satellite side is The terminal device determines the first offset value Δ1 Thus, the starting time t1 of the actual activation time of the cell DRX is t1=t0+Δ1. For another example, considering the TA offset value N TA,offset There can also be on the satellite side, i.e., the uplink and downlink timing offset value on the satellite side is The terminal device determines the first offset value Δ1 That is, if the terminal device can obtain the satellite-side uplink-downlink timing offset value Δ sat , the first offset value Δ1=Δ sat , which can ensure that the starting moment of the actual satellite-side cell DRX active time corresponds to the same physical moment as the starting moment of the cell DTX active time.

[0206] The public determined by the terminal device may have errors, resulting in actual satellite-side uplink-downlink timing offset value Considering the closed-loop TAN TA for compensating the service link and the error of the public , which can be used as an upper limit value of the error of the public . That is, when N TA <0, the terminal device determines the first offset value Δ1=Δ As shown in FIG. 15, when N TA >0, the terminal device determines the first offset value Δ1=Δ That is, the terminal device determines the first offset value Δ1=Δ , so as to ensure that the starting moment of the actual cell DRX active time is not earlier than the starting moment of the cell DTX active time.

[0207] In some embodiments, the method further comprises:

[0208] The terminal device starts uplink transmission at the second time, and / or starts timing the cell DRX active time.

[0209] The terminal device starts uplink transmission at the starting moment of the actual cell DRX active time, and / or starts timing the cell DRX active time.

[0210] In an example, as shown in FIG. 16, the starting moment of the actual cell DRX active time t1=t0+Δ1, and the terminal starts uplink transmission at the moment t1.

[0211] In some embodiments, the wireless communication method provided by the embodiments of the present application is applied to a terminal device, as shown in FIG. 17, and further comprises:

[0212] S1701, the terminal device determines a fourth time, which is the ending moment of the actual cell DRX active time;

[0213] The fourth time is determined based on a fifth time, and the fifth time is an ending moment of a cell DRX active time and / or an ending moment of a cell DTX active time in third configuration information, and the third configuration information includes activated cell DRX configuration information and / or activated cell DTX configuration information in the first information.

[0214] The fourth time can be an ending moment of a cell DRX active time indicated by currently activated cell DRX configuration information, wherein,

[0215] The ending moment of the cell DRX active time can be t0+D after t0, which is a length D of an activation time of a starting moment of the cell DRX active time. The starting moment of the cell DTX active time indicated by the currently activated cell DTX configuration information can refer to the wireless communication method described in FIG. 10, which will not be described here.

[0216] If the terminal device starts timing the cell DRX active time at an actual starting moment of the cell DRX active time, as a possible implementation manner, the ending moment of the actual cell DRX active time, i.e., the fourth time, has a second offset value Δ2 relative to the ending moment of the configured cell DRX active time, i.e., the fifth time.

[0217] For timing of the cell DRX active time, the terminal device can start timing the cell DRX active time at a starting moment t0 of the configured cell DRX active time, and the cell DRX active time ends at t0+D. Alternatively, the terminal device can start timing the cell DRX active time at a starting moment t1 of the actual cell DRX active time, and at this time, the ending moment t2 of the actual cell DRX active time is t0+D+Δ2, so as to fully utilize the on time of the satellite beam.

[0218] In some embodiments, the fourth time is determined based on the fifth time and a second offset value, and the second offset value is determined based on one or more of the following parameters: a timing advance (TA) offset value; a closed loop TA; a common TA.

[0219] The terminal device determines the second offset value Δ2 based on at least one of the following: a TA offset value (N TA,offset ), a closed loop TA (N TA ), and a common

[0220] In an example, as shown in FIG. 16, the network device configures the ending moments of the cell DTX and cell DRX active times as t0+D, and if the satellite side uplink and downlink timing offset value is , the terminal device determines the second offset value Therefore, the actual end time of cell DRX activation is t2 = t0 + D + Δ2. For example, if the uplink / downlink timing offset on the satellite side is... Then the terminal device determines the second offset value. In other words, if the terminal device can obtain the uplink and downlink timing offset value Δ from the satellite side... sat Then let the second offset value Δ2 = Δ sat This ensures that the end time of the actual cell DRX activation time on the satellite side and the end time of the cell DTX activation time correspond to the same physical time.

[0221] Considering the public determined by the terminal equipment There may be errors; similarly, the closed-loop TAN can be used. TA As a public The upper limit of the error. That is, when N TA When <0, Then the terminal device determines the second offset value. As shown in Figure 18, N TA When >0, Then the terminal device determines the second offset value. In other words, the terminal device determines the second offset value. This ensures that the actual end time of the cell DRX activation is no later than the end time of the cell DTX activation.

[0222] This application provides a wireless communication method applied to a terminal device, as shown in FIG19, including:

[0223] S1901, The terminal device receives or transmits a first channel, the transmission of which is related to the cell DTX or cell DRX activation time.

[0224] This application provides a wireless communication method applied to a network device, as shown in FIG20, including:

[0225] S2001. The network device sends or receives a first channel, the transmission of which is related to the cell DTX or cell DRX activation time.

[0226] This application provides a wireless communication method applied to a wireless communication system including terminal devices and network devices, as shown in FIG21, including:

[0227] S2101, The network device sends a first channel to the terminal device or receives a first channel sent by the terminal device, wherein the transmission of the first channel is related to the cell DTX or cell DRX activation time.

[0228] In the embodiments of the present application, the transmission of the first channel between the terminal device and the network device is adjusted based on the cell DTX or cell DRX activation time, so that the channel transmission behavior of the network device and the terminal device adapts to the cell DTX or cell DRX, and the transmission of the first channel in the cell DTX / cell DRX non-activation time is avoided.

[0229] In some embodiments, the first channel includes one or more of the following:

[0237] the network device sends a second DCI, the second DCI scheduling the first channel;

[0238] the scheduling delay of the first channel is counted within the cell DTX or cell DRX activation time.

[0239] In some embodiments, the scheduling delay includes a DCI scheduling delay and / or an NTN scenario configured scheduling delay.

[0240] For a PDSCH scheduled by a second DCI, if the terminal device receives the scheduling DCI at slot n, the PDSCH scheduled by the DCI is received at slot n+K0, where K0 is a DCI scheduling delay.

[0241] In an example, as shown in FIG. 22, the cell DTX is configured, and the DCI scheduling delay K0 is only counted within the cell DTX activation time, so that the scheduled PDSCH transmission occurs outside the cell DTX activation time.

[0242] For DCI scheduled PUSCH, if the terminal device receives the DCI in slot n, the DCI scheduled PUSCH is transmitted in slot n + K2 + K offset The DCI scheduled PUSCH is transmitted in slot n + K2 + K offset The scheduling delay is configured for the NTN scenario.

[0243] In an example, as shown in FIG. 23, if the cell DRX is configured, the DCI scheduling delay K2 and / or the scheduling delay K offset Only count in the cell DRX active time, so as to avoid the scheduled PUSCH transmission occurring outside the cell DRX active time.

[0244] For DCI scheduled PUCCH, if the terminal device receives the DCI or DCI scheduled PDSCH in slot n, the DCI scheduled PUCCH is transmitted in slot n + K1 + K offset The DCI scheduled PUCCH is transmitted in slot n + K1 + K offset The scheduling delay is configured for the NTN scenario.

[0245] In an example, as shown in FIG. 24, if the cell DRX is configured, the DCI scheduling delay K1 and / or the scheduling delay K offset Only count in the cell DRX active time, so as to avoid the scheduled PUCCH transmission occurring outside the cell DRX active time.

[0246] In some embodiments, the repeated transmission of the first channel is counted in the cell DTX or the cell DRX active time.

[0247] If the terminal device is scheduled the repeated transmission of the first channel, the repeated transmission of the first channel is counted in the cell DTX or the cell DRX active time.

[0248] In the embodiments of the present application, if the terminal device is scheduled to perform at least one of PDSCH repeated transmission, PUSCH repeated transmission and PUCCH repeated transmission in N slots, the N slots are only counted in the cell DTX or the cell DRX active time.

[0249] In an example, as shown in FIG. 25, if the terminal device is scheduled to receive PDSCH repeated transmission in N = 4 slots, the first 2 times of PDSCH repeated transmission are received in the first cell DTX active time, and the remaining 2 times of PDSCH repeated transmission are received in the second cell DTX active time, so as to ensure that N = 4 times of PDSCH repeated transmission can be successfully received.

[0250] In some embodiments, the valid CG-PUSCH occasion is related to a cell DRX active time, and the valid CG-PUSCH is used for transmission of the PUSCH.

[0251] For the configured grant CG-PUSCH, the terminal device or the network device determines a valid PUSCH occasion according to a cell DRX active time.

[0252] In some embodiments, the CG-PUSCH occasion within the cell DRX active time is the valid CG-PUSCH occasion.

[0253] Here, the CG-PUSCH occasion within the cell DRX active time is the valid PUSCH occasion.

[0254] In an example, as shown in FIG. 26, the cell DRX cycle is 160 ms, and the CG-PUSCH occasion cycle is 80 ms, where PUSCH occasion #0 and PUSCH occasion #2 are within the cell DRX active time, and PUSCH occasion #1 and PUSCH occasion #3 are outside the cell DRX active time, then PUSCH occasion #0 and PUSCH occasion #2 are valid CG-PUSCH occasions, and PUSCH occasion #1 and PUSCH occasion #3 are invalid CG-PUSCH occasions.

[0255] In the related art, the cell DTX only affects the PDCCH monitoring activity and the semi-persistent scheduling SPS-PDSCH of the connected terminal device, and the cell DRX only affects the scheduling request SR and the configured grant CG-PUSCH of the connected terminal device. However, in the NTN system, the terminal device cannot send or receive any channel to the satellite within the cell DTX / cell DRX inactive time, and therefore, the terminal behavior in the cell DTX / cell DRX needs to be enhanced.
