[0053] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell.

[0054] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0055] 1. Initial access process in NR system

[0056] In an NR system, the initial access process of a terminal device is accomplished by detecting the synchronization signal block (SSB or SS / PBCH block) on the synchronization raster. SSB is transmitted through the discovery signal transmission opportunity window (DBT) or SSB transmission opportunity window (SSB). The discovery signal transmission opportunity window or SSB transmission opportunity window occurs periodically, and the period can be configured by the network device through high-layer parameters.

[0057] One of the main functions of the SSB index is to allow the terminal device to obtain system timing information. In addition, the SSB index has another function, which is to indicate the Quasi Co-Location (QCL) relationship between SSBs. QCL means that the large-scale parameters of the channel experienced by the symbols on a certain antenna port can be inferred from the channel experienced by the symbols on another antenna port. The large-scale parameters may include delay spread, average delay, Doppler spread, Doppler frequency shift, and spatial reception parameters. Specifically for SSB, in the 5G NR system, the SSBs carried by different beams constitute an SSB burst set. Different SSB indices correspond to different SSB time domain position information within the burst set, and also correspond to specific SSB transmission beam information. SSBs with the same SSB index can be considered to have a QCL relationship; in other words, SSBs with the same SSB index experience the same or similar large-scale parameters of the channel. The terminal device can assume that the network device uses the same beam to transmit these SSBs; there is no QCL relationship between the SSBs corresponding to different SSB indices, because they may come from different transmission beams of the network device and experience different channel transmission characteristics.

[0058] During the initial access process, the terminal device attempts to search for the synchronization signal through the predefined possible time-frequency positions of the SSB, and demodulates the PBCH in the SSB after detecting the synchronization signal. The terminal device performs combined detection on the synchronization signals or PBCH with QCL relationship in multiple periods to improve the robustness of SSB detection. After detecting the SSB, the terminal device can obtain time and frequency synchronization, radio frame timing and cell ID (Identifier). The network device will configure the Type0-PDCCH CSS (Type0-Physical Downlink Control Channel Common Search Space) set through the MIB (Master Information Block) information in the SSB. The PDCCH transmitted in the Type0-PDCCH CSS set is used to schedule the PDSCH Physical Downlink Shared Channel carrying SIB1 (System Information Block 1). The terminal device can monitor the PDCCH candidates at the monitoring time of the corresponding Type0-PDCCH CSS set, thereby receiving the scheduling of the corresponding SIB1 message. Similarly, the terminal device can also receive the SIB1 message in a combined manner.

[0059] The terminal device can also obtain resource configuration during the random access process based on the system message received from the cell. The random access process is a very important process in the initial access process. In addition to completing functions such as establishing an RRC connection, maintaining uplink synchronization, and cell handover, the random access process also undertakes functions such as beam management and system message request.

[0060] The resource configuration during the random access process includes PRACH (Physical Random Access Channel) resource configuration, also known as RO (PRACH Occasion). RO is the time-frequency resource that carries the random access preamble. If two-step RACH (Random Access Channel) transmission is supported, the resource configuration during the random access process also includes PUSCH (Physical Uplink Shared Channel) resource configuration, also known as PUSCH Occasion (PO). Message A (MsgA) in the two-step RACH includes MsgA Preamble and MsgA PUSCH. RO is the time-frequency resource used to carry the MsgA Preamble, and PO is the time-frequency resource used to carry the MsgA PUSCH.

[0061] The characteristic of the NR system is that it supports downlink multi-beam. Before the network device communicates with the terminal device, the network device needs to know the beam where the terminal device is located and then set the appropriate beam direction in the subsequent data transmission process. Since the PRACH in the random access process is the first information sent by the terminal device to the network device, the function of reporting the beam where the terminal device is located can be carried by the PRACH. Specifically, it can be determined by the mapping relationship between SSB and RO. After the terminal device determines the target SSB, it can transmit PRACH according to the RO associated with the target SSB. The association relationship between RO and SSB is as follows:

[0062] ●1 RO is associated with N SSBs, and each SSB corresponds to R PRACH sequences used to compete for RACH transmission.

[0063] ○When N<1, 1 SSB can be associated with (1 / N) ROs.

[0064] ○When N=1, one SSB can be associated with one RO.

[0065] ○When N>1, multiple SSBs can be associated with one RO, where the maximum value of R corresponding to each SSB is (64 / N).

[0066] ●The PRACH sequence corresponding to each SSB can be divided into group A and group B.

[0067] ●The total number of PRACH sequences used for contention RACH transmission includes N*R.

[0068] The association order between RO and SSB is as follows:

[0069] ● When associating, first sequence, then arrange the frequency domain ROs of FDM (Frequency Division Multiplexing) in the same time unit in sequence, then arrange the different time domain ROs in the same time slot in sequence, and finally arrange the ROs in different time slots in sequence.

[0070] ●For the case indicated by PDCCH order (Physical Downlink Control Channel order), PRACH sequence ID (Identifier) ​​is indicated, PRACH opportunity is indicated by mask ID, and the association order is firstly the frequency domain ROs of FDM on the same time unit are arranged in sequence, then the different time domain ROs on the same time slot are arranged in sequence, and finally the ROs on different time slots are arranged in sequence.

[0071] The association relationship between RO and SSB is repeated periodically. The association period is determined based on the PRACH configuration period, and one association period includes at least one association relationship between N SSB indices and their corresponding ROs. Within one association period, the association relationship between N SSB indices and their corresponding ROs occurs an integer number of times. After an integer number of mappings, if there are any remaining ROs or PRACH sequences that are not mapped to SSB indices, these ROs or PRACH sequences are not associated with SSB indices. An association pattern period includes one or more association periods, one of which is 160ms, meaning that the association relationship between RO and SSB is repeated periodically for a maximum of 160ms.

[0072] 2. Measurement Mechanism in NR Systems

[0073] In NR systems, to ensure the quality of service and mobile connectivity of terminal devices, terminal devices need to perform RLM (Radio Link Monitoring), RRM (Radio Link Monitoring, Radio Resource Management) measurements and BFR (Beam Failure Recovery) mechanisms.

[0074] RRM measurements

[0075] For wireless mobile communication systems, accurate measurement of cell quality and beam quality is fundamental to effective radio resource management and mobility management. There are two types of configurable measurement reference signals: CSI-RS (Channel State Information-Reference Signal) and SSB.

[0076] For SSB-based measurements, the network device configures SSB measurement resources to the UE through higher-layer signaling, so that the UE can perform the corresponding measurement operation. For CSI-RS-based measurements, the network device can configure one or more CSI-RS resources for the UE to perform measurements through higher-layer signaling.

[0077] With the above configuration parameters, the UE will know which reference signals should be measured within which time and frequency domain resource ranges. The terminal device's same-frequency or different-frequency measurements require sufficient reference signal samples to be obtained within the unit measurement time to meet certain measurement accuracy requirements (such as RSRP (Reference Signal Received Power), RSRQ (Reference Signal Receiving Quality) and SINR (Signal to Interference Plus Noise Ratio) measurement accuracy), and evaluate the relevant measurement results before reporting them to the network.

[0078] In a conditional handover, the network pre-configures candidate target cells and handover command information to the terminal device. When specific conditions are met, the terminal device can autonomously execute the configuration in the handover command and directly initiate handover access to the target cell that meets the conditions. Because the terminal device no longer triggers measurement reporting when the handover conditions are met, and the terminal device has already obtained the configuration in the handover command in advance, it avoids the possibility of measurement reporting or handover command failure during the handover process, thereby improving the handover success rate.

[0079] In order to improve the service performance in MR-DC (Multi-Radio-DC, multi-radio dual connection) mode, the function of quickly establishing SCell / SCG is supported, allowing the terminal device to perform measurements in idle state or inactive state, and report the measurement results to the network side immediately after entering the RRC (Radio Resource Control) connection state, so that the network side can quickly configure and establish SCell / SCG (Secondary Cell / Secondary Cell Group).

[0080] In the SCell Dormancy topic, when the SCell / SCG is activated but no data is being transmitted, a dedicated Dormant Bandwidth Part (BWP) is configured via RRC. This means that the UE does not monitor the PDCCH on this BWP and only performs CSI measurements and reporting, thus saving power. When data transmission is required, dynamic indications can be used to quickly switch the UE to an active state, allowing for rapid service recovery.

[0081] BFR Mechanism

[0082] In NR systems, analog beamforming technology can be used to achieve cell coverage. To improve the robustness of analog beam transmission, when the current beam transmission quality deteriorates to a certain level, the terminal device proactively searches for a new beam with better link quality and notifies the network, thereby reestablishing a high-quality, reliable communication link using the new beam. This processing method is called the BFR mechanism, or beam recovery mechanism.

[0083] The beam failure recovery mechanism has four main steps:

[0084] Beam Failure Detection (BFD).

[0085] Only a single-port periodic CSI-RS can be used for beam failure detection. Specifically, the network can explicitly configure the periodic CSI-RS for beam failure detection through signaling. Alternatively, if the network does not explicitly configure the periodic CSI-RS, the terminal uses the periodic CSI-RS in the activated TCI-state of the CORESET corresponding to the PDCCH channel for beam failure detection.

[0086] ●NBI (New Beam Identification)

[0087] ○ The network pre-configures a set of candidate beams (such as CSI-RS and / or SSB) for the terminal. The terminal measures the set of candidate beams and selects the beam that meets a certain threshold as the new beam.

[0088] ●BFRQ (Beam Failure Recovery Request)

[0089] ○ For the primary cell (PCell) and the secondary primary cell (PSCell), the terminal initiates a beam failure recovery request (BFRQ) process through PRACH, notifying the network of a beam failure and reporting a new beam. Specifically, the network pre-configures a set of candidate beams (such as CSI-RS signals and / or SSBs) for the terminal and configures corresponding PRACH resources and random access preambles for each SSB / CSI-RS. When the terminal determines that a beam is a new beam, it uses the PRACH resources corresponding to the new beam to send the corresponding random access preamble. After receiving it, the network knows that the terminal has experienced a beam failure.

[0090] For the secondary cell (SCell), BFR MAC CE reporting can be transmitted via PUSCH in the primary cell or in the secondary cell. If there are currently insufficient uplink resources to send a BFR MAC Control Element (BFR MAC Control Element), the terminal can request uplink resources to send a BFR MAC CE by sending a Selective Repeat (SR).

[0091] ●Network-side response.

[0092] For the primary cell (PCell) and secondary primary cell (PSCell), if the terminal detects the network's Downlink Control Information (DCI) on the new beam within the random access response window, the beam recovery is considered successful. If the terminal does not detect the network's DCI on the new beam within the random access response window, it can resend the BFRQ. This process can be repeated until the beam recovery process is successful or the number of BFRQ retransmissions exceeds the threshold specified by the network.

[0093] For the secondary cell (SCell), the network can determine whether the MAC CE signaling has been correctly received by the network through the existing PUSCH HARQ (Hybrid Automatic Repeat Request) related mechanism. If the terminal receives an uplink grant for scheduling new data corresponding to the same HARQ process, it is considered that the previous transmission has been correctly received by the network.

[0094] 3. Frequency Hopping Transmission in NTN System

[0095] In an NTN system, satellites provide services to the ground over a large area. Given the limited total transmit power of satellites, ground-based terminal devices must meet the required SNR (Signal to Noise Ratio) for different downlink channels to properly access the satellite network. Assuming a system bandwidth of 30 MHz and a total satellite transmit power of 18.8 dBW, to meet the required SNR for different downlink channels, the satellite can have up to 24 active satellite antenna beams at any given moment, each corresponding to a coverage area of ​​50 km in diameter. To achieve the coverage of a single satellite using 24 active satellite antenna beams, analog beamforming can be used. Phase shifters are used to change the phase of each antenna's corresponding channel, allowing a group of antennas to form beams in different directions. This allows for beam sweeping, achieving satellite coverage. This involves using beams in different directions at different times to cover different areas within the satellite's coverage area. Based on these assumptions, Table 1 provides satellite coverage information for different minimum UE elevation angles.

[0096] Table 1: Satellite coverage information

[0097] In an embodiment of the present application, the above-mentioned method of achieving satellite coverage through beam scanning can also be referred to as discontinuous communication transmission. Figure 7 shows a schematic diagram of the discontinuous communication transmission scenario. As shown in Figure 7, different areas in the satellite coverage are associated with different cells, or different areas in the satellite coverage are associated with different cell groups. The satellite can have up to M groups of activated satellite antenna beams at each moment, where each group of satellite antenna beams corresponds to the coverage of a cell, and the satellite corresponds to the coverage of a cell group at each moment, and each cell group includes M cells. At time t0, M groups of satellite antenna beams serve the first cell group (cell-i, cell-j, ..., cell-m); at time t1, the M groups of satellite antenna beams switch to serving the second cell group (cell-i+1, cell-j+1, ..., cell-m+1); ..., and so on, until satellite coverage is achieved. The service time of each cell is the time length between two adjacent moments. For example, the service time of the cells in the first cell group is the time length between time T0 and time T1.

[0098] In the discontinuous transmission scenario of an NTN system, satellites achieve cell coverage through beam scanning. Each cell is served discontinuously. In this scenario, it's unclear how to enhance discontinuous transmission systems to improve signal accuracy and avoid unnecessary power consumption.

[0099] An embodiment of the present application provides a wireless communication method, assuming that a satellite can have a maximum of M groups of activated satellite antenna beams per time period, and each group of satellite antenna beams corresponds to the coverage range of one cell, that is, each time period of the satellite corresponds to the coverage range of a cell group, and each cell group includes M cells. In order to achieve satellite coverage, the number of time periods required for satellite antenna beam scanning is N, that is, the satellite needs to serve N cell groups through beam scanning. The coverage range of the satellite includes a total of M*N cells. Among them, the service time of each cell is the time length between two adjacent moments. For example, the service time of a cell in the nth cell group is the time length between moment Tn and moment Tn+1, n=0,1,…,N-1.

[0100] Because network equipment provides discontinuous communication transmission via satellite antenna beam scanning, the serviceable time for each cell can be planned in advance. In this case, the network equipment can inform the terminal device of this information, so that the terminal device can turn on the radio frequency for uplink and downlink communication during the time period when the network equipment is providing service to the terminal device's cell, and turn off the radio frequency for uplink and downlink communication during the time period when the network equipment is not scheduled to provide service to the terminal device's cell. This improves the accuracy of communication transmission and avoids meaningless power consumption, achieving the goal of saving power for the terminal device.

[0101] Please refer to Figure 8, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method can be applied to the network architecture shown in Figures 1 to 6. The method includes at least one of the following steps 810 to 820.

[0102] In step 810, the terminal device receives the first indication information sent by the network device, where the first indication information is used to determine the first information and / or the second information. The first information is used to determine the time domain resources for which the network device provides services for the first cell, and the second information is used to determine the time domain resources for which the network device does not provide services for the first cell. The first cell is the service cell of the terminal device.

[0103] Correspondingly, the network device sends the first indication information to the terminal device.

[0115] 2. The first indication information is used to determine the second information

[0116] In some embodiments, the first indication information may be used to determine the second information in the following two cases:

[0117] Case 1: the first indication information is used to indicate the second information.

[0118] Case 2: The first indication information is used to indicate the first information, and the terminal device determines the second information based on the first information.

[0128] As shown in Figure 7, different areas within the satellite's coverage area are associated with different cells, or alternatively, different areas within the satellite's coverage area are associated with different cell groups. A satellite can have up to M active satellite antenna beams per time period, with each group corresponding to the coverage area of ​​one cell. Each satellite time period corresponds to the coverage area of ​​one cell group, with each cell group containing M cells. The at least one cell group is the cell group associated with each area within the satellite's coverage area.

[0132] In some embodiments, which one or more of the above three situations are included in the service time length of at least one cell group can be determined based on the service time length of each cell group. For example, if the service time length of each cell group is the same, then it can be the service time length of only one of the cell groups. For another example, if the service time length of each cell group is different, then the service time length of each cell group can be indicated. For another example, if there is only one cell group whose service time length is different from that of other cell groups, then the service time length of the cell group and the service time length of other cell groups can be indicated. In some embodiments, the method for determining the service time length of each cell group in the following embodiments can be referred to to determine how to indicate the service time length of at least one cell group.

[0133] In some embodiments, the service configuration of the first cell includes discontinuous service and continuous service. Discontinuous service is also called frequency hopping transmission. The service configuration of the first cell may include whether the first cell is configured with frequency hopping transmission.

[0134] In some embodiments, at least one of the following is predefined: the number of cell groups, the service time length of at least one cell group, the service time cycle length, the starting position of the service time of at least one cell group, the cell group number where the first cell is located, and the service configuration of the first cell.

[0135] In some embodiments, if the first indication information indicates one of the above-mentioned contents, the information does not need to be predefined; correspondingly, if one of the above-mentioned contents is predefined, the first indication information does not need to indicate the information.

This also avoids meaningless power consumption and achieves the purpose of power saving for the terminal device. In addition, the terminal device can also determine the effective resources in the cell network based on the above indication information.

[0170] Regarding how a terminal device determines resources for transmission in the first cell, this application provides the following embodiments.

[0172] In some embodiments, the terminal device determines the resources for transmitting the first downlink channel or signal in the first cell based on the intersection between the time domain resources used by the network device to provide services for the first cell and the time domain resources allocated by the network device for transmitting the first downlink channel or signal, wherein the time domain resources used by the network device to provide services for the first cell are determined based on the first information.

[0173] In some embodiments, the terminal device determines the resources for transmitting the first downlink channel or signal in the first cell based on the intersection between the time domain resources used by the network device to provide downlink services for the first cell and the time domain resources allocated by the network device for transmitting the first downlink channel or signal, wherein the time domain resources used by the network device to provide downlink services for the first cell are determined based on the first information.

[0174] In some embodiments, the time domain resources allocated by the network device for transmitting the first downlink channel or signal may be dynamically scheduled or semi-statically configured, which is not limited in this application.

[0175] Exemplarily, the first downlink channel or signal includes a PDSCH, and the PDSCH includes a PDSCH dynamically scheduled by DCI and / or a PDSCH semi-statically configured.

[0176] Exemplarily, the first downlink channel or signal includes a CSI-RS, and the CSI-RS includes a CSI-RS dynamically scheduled by DCI and / or a CSI-RS semi-statically configured.

[0177] 2. The first indication information is used to determine the first information, and the resources used for the first cell transmission include the resources used for transmitting the first uplink channel or signal in the first cell.

[0178] In some embodiments, the terminal device determines the resources for transmitting the first uplink channel or signal in the first cell based on the intersection between the time domain resources used by the network device to provide services for the first cell and the time domain resources allocated by the network device for transmitting the first uplink channel or signal, wherein the time domain resources used by the network device to provide services for the first cell are determined based on the first information.

[0179] In some embodiments, the terminal device determines the resources for transmitting the first uplink channel or signal in the first cell based on the intersection between the time domain resources for providing uplink services to the first cell by the network device and the time domain resources allocated by the network device for transmitting the first uplink channel or signal, wherein the time domain resources for providing uplink services to the first cell by the network device are determined based on the first information.

[0180] In some embodiments, the time domain resources allocated by the network device for transmitting the first uplink channel or signal may be dynamically scheduled or semi-statically configured, which is not limited in this application.

[0181] Exemplarily, the first uplink channel or signal includes a PRACH, and the PRACH includes a PRACH dynamically scheduled by DCI and / or a PRACH semi-statically configured.

[0182] Exemplarily, the first uplink channel or signal includes a PUSCH, and the PUSCH includes a PUSCH dynamically scheduled by DCI and / or a PUSCH semi-statically configured.

[0183] Through the above method, the terminal device can determine the resources used for transmission in the first cell based on the first indication information. The terminal device can turn on the radio frequency for uplink and downlink communications during the time period when the network device provides services for the cell where the terminal device is located, and turn off the radio frequency and stop uplink and downlink communications during the time period when the network device does not plan to provide services for the cell where the terminal device is located, thereby achieving the purpose of saving power for the terminal device. In addition, the terminal device can also determine the available resources in the cell network based on the above indication information.

[0184] Regarding how to determine the first information and / or the second information, this application provides the following embodiments.

[0185] In some embodiments, the first information and / or the second information is determined based on an association relationship between at least one cell group and a service time of at least one cell group, wherein:

[0186] The service time length in the i-th cell group includes the time length from i*S to (i+1)*S-1.

[0187] Wherein, i represents the number of the cell group, i=0, 1,…, N-1, N represents the number of cell groups, N is a positive integer, and S represents the service time length of each cell group.

[0188] Optionally, the unit of S may be one of the following: radio frame, subframe, time slot, symbol, millisecond, or second.

[0189] Exemplarily, the service time length in the first cell group includes a time length between 1*S and 2*S-1. For example, if S=10 ms, the service time length in the first cell group includes a time length between 10 ms and 19 ms.

[0190] In some embodiments, the starting position of the service time of the 0th cell group is the starting position of the radio frame numbered T*F, where the service time period length is T radio frames, T is a positive integer, and F is an integer.

[0191] The service time period is T consecutive radio frames starting from the radio frame numbered T*F. In other words, starting from the radio frame numbered T*F, every T consecutive radio frames constitute a service time period.

[0192] The value of F can be integers such as 0, 1, 2, etc.

[0193] Exemplarily, T=2, F=0, 1, 2, ... and other integers, then the starting position of the service time of the 0th cell group is the starting position of the radio frame numbered 0, 2, 4, ..., etc. 2*F. Exemplarily, T=4, F=0, 4, 8, ... and other integers, then the starting position of the service time of the 0th cell group is the starting position of the radio frame numbered 0, 4, 8, ..., etc. 4*F.

[0194] In some embodiments, a radio frame is 10 ms long.

[0195] In some embodiments, the starting position of the service time of the 0th cell group is determined by the first indication information.

[0196] In some embodiments, the service time length S of each cell group is determined by the service time period length T and the number N of cell groups.

[0197] In some embodiments, the service time period is T radio frames in length.

[0198] In some embodiments, the service time length S of each cell group is determined by first indication information.

[0199] In some embodiments, the service time length S of each cell group is determined by the service time period length T and the number of cell groups N, including one of the following situations:

[0200] The service time length of each cell group is S = (T*10) / N;

[0201] The service time length of each cell group except the last cell group is S=ceil((T*10) / N), and the service time length of the last cell group is (T*10)-(N-1)*S, where ceil means rounding up;

[0202] The service time length of each cell group except the last cell group is S = floor((T*10) / N), and the service time length of the last cell group is (T*10)-(N-1)*S, where floor means rounding down;

[0203] The length of the service time period is T radio frames.

[0204] In some embodiments, if S calculated by S=(T*10) / N is not an integer, then except for the last cell group, the service time length of other cell groups is S, and the service time length of the last cell group is (T*10)-(N-1)*S.

[0205] For example, assuming that T is 5 radio frames and N is 7 cell groups, the service time length of each cell group except the last cell group is S = ceil((T*10) / N) = ceil(50 / 7) = 8 ms, and the service time length of the last cell group is (T*10)-(N-1)*S=50-(7-1)*8=2 ms.

[0206] For example, assuming T is 5 radio frames and N is 7 cell groups, the service time length of each cell group except the last cell group is S = floor((T*10) / N) = ceil(50 / 7) = 7 ms, and the service time length of the last cell group is (T*10)-(N-1)*S=50-(7-1)*7=8 ms.

[0207] In some embodiments, the above methods for determining the service time length S for each cell group are parallel solutions and can be used interchangeably, and this application does not limit this. Optionally, the specific method used to determine the service time length for each cell group can be configured by the network device or predefined. This application also provides an exemplary description of the above methods for determining the service time length S for each cell group.

[0208] Exemplarily, the first indication information is used to indicate that the starting position of the service time of each cell group is i*S, where i is the number of the cell group, i=0, 1,…, N-1. The service time of the cell in the i-th cell group is the time length between i*S and (i+1)*S-1. Assuming that the service time cycle length T (the service time cycle length is T radio frames) is 4, then starting from the radio frame numbered 4*F, within every four consecutive radio frames, the terminal device can determine the starting position of the service time of each cell group according to i*S, and determine the end position of the service time of each cell group according to (i+1)*S, that is, the service time of the cell in the i-th cell group is from i*S to (i+1)*S-1 milliseconds within every four consecutive radio frames.

[0209] Exemplarily, the first indication information is used to indicate the number N of cell groups and the service time length S of each cell group, where N and S are positive integers. Where N = 10, S = 5 ms, the starting position of the service time of the 0th cell group starts from the radio frame numbered 5*F, and the value of F can be an integer such as 0, 1, 2, ..., then the service time of the 0th cell group is from 0 to 4 milliseconds of the radio frame 5*F, the service time of the 1st cell group is from 5 to 9 milliseconds of the radio frame 5*F, the service time of the 2nd cell group is from 0 to 4 milliseconds of the radio frame 5*F+1, ..., and the service time of the 9th cell group is from 5 to 9 milliseconds of the radio frame 5*F+4. As shown in Figure 9, assuming that the first indication information is also used to determine that the cell group number of the first cell is the second cell group, since the service time of the second cell group is the 0th to 4th milliseconds of the wireless frame 5*F+1, the terminal device can determine that the first information is the 0th to 4th milliseconds of the wireless frame 5*F+1, and the second information is the 5th to 9th milliseconds of the wireless frames 5F, 5*F+1, 5*F+2, 5*F+3, and 5*F+4.

[0210] Exemplarily, the first indication information is used to indicate the number N of cell groups and the length of the service time period T, where N and T are positive integers, and the length of the service time period is T radio frames. Where N=5, T=2, the service time length S of each cell group is (T*10) / N=4ms. Starting from the even-numbered radio frames, within every two consecutive radio frames, the terminal device can determine the starting position of the service time of each cell group based on n*S, where n is the number of the cell group, n=0, 1,…, N-1. That is, the service time of the cell in the nth cell group is from n*S to (n+1)*S-1 milliseconds within every two consecutive radio frames. As shown in Figure 10, assuming that the first indication information is also used to determine that the cell group number of the first cell is the second cell group, the terminal device can determine the service time of the second cell group as the 8th to 11th milliseconds in every two consecutive wireless frames based on the above information, and then determine the first information as the 8th to 11th milliseconds in every two consecutive wireless frames, and the second information as the 0th to 7th milliseconds and 12th to 19th milliseconds in every two consecutive wireless frames.

[0211] Exemplarily, the first indication information is used to indicate the number N of cell groups and the length of the service time period T, where N and T are positive integers and the length of the service time period is T radio frames. Where N = 3 and T = 2, then except for the last cell group, the service time length S of each cell group is ceil((T*10) / N) = 7 ms, and the service time length of the last cell group is (T*10)-(N-1)*S = 6 ms.

[0212] Exemplarily, the first indication information is used to indicate the number N of cell groups and the length of the service time period T, where N and T are positive integers and the length of the service time period is T radio frames. Where N = 3 and T = 2, then except for the last cell group, the service time length S of each cell group is floor((T*10) / N) = 6 ms, and the service time length of the last cell group is (T*10)-(N-1)*S = 8 ms.

[0213] Through the above method, the terminal device can determine the service time length of each cell group, and based on the correlation between at least one cell group and the service time of at least one cell group, further determine the time period during which the network device provides service to the terminal device, or the time period during which the network device does not provide service to the terminal device.

[0214] In some embodiments, the first information and / or the second information is determined based on a service configuration of the first cell.

[0215] In some embodiments, the terminal device determines the first information and / or the second information when the service configuration of the first cell is configured as discontinuous service or when the service configuration of the first cell is not configured as continuous service.

[0216] In some embodiments, when the service configuration of the first cell is configured as continuous service or when the service configuration of the first cell is not configured as discontinuous service, the terminal device does not determine the first information and / or the second information.

[0217] In some embodiments, the terminal device determines the first information and / or the second information only when it is determined that the service configuration of the first cell is configured as discontinuous service, or when it is determined that the service configuration of the first cell is not configured as continuous service.

[0218] In some embodiments, the terminal device does not determine the first information and / or the second information when the service configuration of the first cell is configured as continuous service, or when it is determined that the service configuration of the first cell is not configured as discontinuous service.

[0219] Through the above method, the terminal device can determine whether to determine the first information and / or the second information based on the service configuration of the first cell, and then determine the time period when the network device provides services to the terminal device, or the time period when the network device does not provide services to the terminal device.

The terminal device periodically reports the IS / OOS status evaluation results to higher layers. If the measurement result of any of the configured RLM-RSs exceeds the IS threshold, the physical layer reports the IS status to higher layers. If the measurement results of all configured RLM-RSs are below the OOS threshold, the physical layer reports the OOS status to higher layers.
