Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method and related devices. Background Art

[0002] With the continuous development of cellular communication technology, network transmission bandwidth is increasing, and the number of transmission channels is also increasing dramatically, which leads to an increase in the power consumption of network equipment and terminal equipment. In order to reduce the power consumption of communication systems, two energy-saving technologies, cell discontinuous transmission (cell DTX) and cell discontinuous reception (cell DRX), have been proposed. The basic idea of ​​these two energy-saving technologies is to configure a cycle consisting of active time and inactive time. When the energy-saving technology is activated, the network equipment and terminal equipment will not transmit some channels / signals during the inactive period of this cycle, thereby achieving the purpose of saving the power consumption of the communication system.

[0003] In the prior art, the network device instructs the terminal device to activate / deactivate cell DTX and cell DRX through multicast downlink control information (i.e., group-commom DCI). Since multicast DCI generally does not have an automatic repeat request feedback (hybrid automatic repeat request-acknowledge, HARQ-ACK) mechanism, when the terminal device cannot receive the multicast DCI, the terminal device and the network device cannot consistently activate / deactivate the DTX / DRX of the cell, which will seriously affect the transmission performance of the communication system. Summary of the invention

[0004] In order to solve the above problems, the present application provides a communication method and related devices, which can reduce the damage to the transmission performance of the communication system caused by the discontinuous transmission of the activation / deactivation cell that the terminal device and the network device cannot consistently activate / deactivate.

[0005] In a first aspect, an embodiment of the present application provides a communication method. The communication method is applicable to a terminal device. The method includes detecting target indication information sent by a network device. The target indication information is used to activate or deactivate target discontinuous transmission of a first cell. If it is determined that the target indication information is not detected, a first preset signal / channel is not transmitted in a target time period, and / or a second preset signal / channel is transmitted in a target time period.

[0006] In the above implementation, it is specified how to transmit the first preset signal / channel and / or the second preset signal / channel when the terminal device detects but does not receive the indication information for indicating the activation / deactivation of the discontinuous transmission of a certain cell. This can reduce the damage to the transmission performance of the communication system caused by the discontinuous transmission of the cell that the terminal device and the network device cannot consistently activate / deactivate, and can make the transmission performance of the communication system more stable and the transmission efficiency higher.

[0007] In combination with the first aspect, in a feasible implementation method, the target time period is an inactive time period within the current cycle of the target non-continuous transmission of the first cell, and / or an inactive time period within Y cycles after the current cycle, where Y is a positive integer equal to or greater than 1.

[0008] In combination with the first aspect, in a feasible implementation manner, the target time period is an inactive time period of the target discontinuous transmission contained in a target period, and the target period is different from a period of a search space indication associated with the target indication information.

[0009] In combination with the first aspect, in a feasible implementation, the terminal device may receive the cycle configuration information sent by the network device, wherein the cycle configuration information includes the cycle length and the starting offset of the target cycle, and the preset cycle is determined according to the cycle length and the starting offset.

[0010] In combination with the first aspect, in a feasible implementation method, the target discontinuous transmission is a first discontinuous transmission DTX, and the first preset signal / channel includes at least one of the following: a periodic CSI reference signal P-CSI-RS for channel state information CSI reporting, a semi-persistent CSI reference signal SP-CSI-RS for CSI reporting, a P-CSI-RS for wireless link management, an SP-CSI-RS for wireless link management, a P-CSI-RS for beam failure detection, an SP-CSI-RS for beam failure detection, a P-CSI-RS for beam failure recovery, an SP-CSI-RS for beam failure recovery, a P-CSI-RS for wireless resource management, an SP-CSI-RS for wireless resource management, a P-CSI-RS for beam management, an SP-CSI-RS for beam management, a P-CSI-RS for tracking, an SP-CSI-RS for tracking, a P-CSI-RS for positioning, and an SP-CSI-RS for positioning.

The limitation on the first preset signal / channel can prevent the terminal device from receiving such signals / channels during inactive periods, thereby ensuring the accuracy of the measurement results of the terminal device and reducing the adverse effects on link performance. The limitation on the second preset signal / channel can enable the terminal device to receive such signals / channels during inactive periods of DTX, thereby reducing the adverse effects on the transmission performance of such signals / channels. In this way, the damage to the transmission performance of the communication system caused by the inability of the terminal device and the network device to consistently activate / deactivate the first DTX of the first cell can be effectively reduced, and the transmission reliability of the communication system can be improved.

[0013] In combination with the first aspect, in a feasible implementation, the first cell is also configured with at least one second DTX, the period of the first DTX is longer than or equal to the period of each second DTX in the at least one second DTX, and / or the active period of the first DTX is shorter than or equal to the active period of each second DTX.

[0014] In the above implementation, when the first cell of the terminal device is configured with multiple DTXs, it is clarified according to which DTX the terminal device transmits the first preset signal / channel mentioned above, thereby reducing the damage to the transmission performance of the communication system when the first cell is configured with multiple DTXs.

[0020] In the above implementation, when the first cell of the terminal device is configured with DRX, it is specified how to transmit the preset first preset signal / channel, and / or the second preset signal / channel when the terminal device does not receive the target indication information for indicating the activation / deactivation of DRX of the first cell, and the specific content of the first preset signal / channel, and / or the second preset signal / channel is further limited. The limitation on the first preset signal / channel can make the terminal device not send such signal / channel during the inactive period of DRX, ensure that the network device can correctly receive such uplink transmission, and reduce the adverse effect on link performance. The limitation on the second preset signal / channel can make the terminal device send such signal / channel during the inactive period of DRX, ensure that the network device can receive such transmission, so as to reduce the adverse effect on link performance. In this way, the damage to the transmission performance of the communication system caused by the inability of the terminal device and the network device to consistently activate / deactivate the first DRX of the first cell can be effectively reduced, thereby improving the transmission reliability of the communication system.

Alternatively, not transmitting a first preset signal / channel during a target period of the first cell, and / or transmitting a second preset signal / channel during a target period of the first cell.

[0027] In the above implementation, since the occurrence of the target event will result in the inability to transmit the target indication information for indicating the target non-continuous transmission of activating / deactivating the first cell between the terminal device and the network device, the specific behaviors of the terminal device and the network device when the target event occurs are specified. This can also reduce the damage to the transmission performance of the communication system caused by the non-continuous transmission of the activation / deactivation cell that the terminal device and the network device cannot consistently activate / deactivate.

Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The wireless access network 100 may include at least one wireless access network device (such as Figure 1 110a and 110b), and may further include at least one terminal (such as Figure 1 120a-120j in the figure). The terminal is connected to the wireless access network device by wireless means, and the wireless access network device is connected to the core network by wireless or wired means. The core network device and the wireless access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated on the same physical device, or part of the functions of the core network device and part of the functions of the wireless access network device can be integrated on one physical device. Terminals and wireless access network devices can be connected to each other by wired or wireless means. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Figure 1 Not drawn in.

[0119] The wireless access network equipment may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation base station in the sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes part of the functions of a base station, for example, it may be a central unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and may also complete the functions of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and may also complete the functions of part or all of the physical layer. For the specific description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The wireless access network device can be a macro base station (such as Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For ease of description, the following description takes the network device as an example of the wireless access network device.

[0120] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

The network equipment and terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons and artificial satellites. The embodiments of the present application do not limit the application scenarios of the network equipment and terminals.

[0122] The roles of network devices and terminals can be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile network device. For the terminals 120j that access the wireless access network 100 through 120i, the drone 120i is a network device; but for the network device 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, network devices and terminals can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having network device functions. Figure 1 120a-120j in the figure can be called communication devices with terminal functions.

The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0124] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem including the network device function. The control subsystem including the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, smart city, etc. The functions of the terminal may also be performed by a module (such as a chip or a modem) in the terminal, or by a device including the terminal function.

[0125] In order to make the purpose, technical solution and advantages of the present application more clear, the present application will be further described in detail below in conjunction with the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment.

[0126] Below, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0127] (1) Cell discontinuous transmission (cell DTX) and cell discontinuous reception (cell DRX)

[0128] In order to achieve the purpose of energy saving for a communication system (including terminal devices and network devices), the prior art provides a method: configuring a cell of a terminal device with a period including an active time and an inactive time. During the inactive time period of this period, the terminal device does not send some signals / channels, and the network device does not receive these signals / channels. Only during the active time period of this period will the terminal device send these signals / channels, and the network device will receive these signals / channels. Such energy-saving technology is called cell DTX, and such a period is also the period of cell DTX. It should be understood that in the embodiments of the present application, cell DTX can also be referred to as DTX, and these two expressions can be equivalently replaced. For the convenience of expression, it is uniformly expressed as DTX in the following text.

[0129] Similarly, the prior art also provides another way: configuring a cell for a terminal device with a period including an active time and an inactive time. During the inactive time of this period, the terminal device does not receive some signals / channels, and the network device does not send these signals / channels. Only during the active time period of this cycle will the terminal device receive these signals / channels, and the network device will also send these signals / channels. This energy-saving technology is called cell DRX. It should be understood that in the embodiments of the present application, cell DRX can also be referred to as DRX, and these two expressions can be equivalently replaced. For the convenience of expression, it is uniformly expressed as DRX in the following text.

[0130] It should be understood that when a cell is configured with DTX or DRX, it is effective for all terminal devices in the cell, or in other words, the network equipment can indicate DTX or DRX to all users in the cell through relevant information, or in other words, all users in the cell use the same DTX or DRX.

[0131] In actual implementation, DTX or DRX can be configured at the cell granularity. The network device can configure DTX for a cell of the terminal device through RRC signaling. In the actual communication process, the network device can instruct the terminal device to activate / deactivate DTX for the cell through multicast DCI or MAC control element (CE). Similarly, the network device can also configure DRX for a cell of the terminal device through RRC signaling, and instruct the terminal device to activate / deactivate DRX for the cell through multicast DCI or MACCE.

[0132] It is important to understand that activating DTX means making the cell's DTX effective, or in other words, making the terminal device receive some signals / channels during the active period of the cell's DTX cycle, and not receiving these signals / channels during the inactive period of the cell's DTX cycle (at this time, the network device sends some signals / channels during the active period of the cell's DTX cycle, and does not send these signals / channels during the inactive period of the cell's DTX cycle). Deactivating the cell's DTX means making the cell's DTX ineffective, or in other words, making the terminal device receive these signals / channels at any time unit within the cell's DTX cycle (at this time, the network device can send these signals / channels at any time unit within the cell's DTX cycle), or making the terminal device receive these signals / channels during the inactive period of the cell's DTX cycle (at this time, the network device can also send these signals / channels during the inactive period of the cell's DTX cycle). Similarly, activating DRX means making the DRX of the cell effective, or in other words, making the terminal device send some signals / channels during the active period of the DRX cycle of the cell, and not sending these signals / channels during the inactive period of the DRX cycle of the cell (at this time, the network device receives some signals / channels during the active period of the DRX cycle of the cell, and does not receive these signals / channels during the inactive period of the DRX cycle of the cell). Deactivating the DRX of the cell means making the DRX of the cell invalid, or in other words, making the terminal device send these signals / channels at any time unit within the DRX cycle of the cell (at this time, the network device can receive these signals / channels at any time unit within the DRX cycle of the cell), or making the terminal device send these signals / channels during the inactive period of the DRX cycle of the cell (at this time, the network device can also receive these signals / channels during the inactive period of the DRX cycle of the cell). For the convenience of explanation, the following text will uniformly express them in the form of activation / deactivation.

[0133] For any cell of the terminal device, it can be configured with only one DTX or DRX, or multiple DTX or multiple DRX. In the case where multiple DTX are configured in the arbitrary cell, only one DTX will be activated or effective at the same time, and the remaining DTX will be deactivated or invalid. Similarly, in the case where multiple DRX are configured in the arbitrary cell, only one DRX will be activated or effective at the same time, and the remaining DTX will be deactivated or invalid;

[0134] It should be noted that DTX or DRX is only an abbreviation of the above two energy-saving technologies. In actual implementation, the above two energy-saving technologies can be respectively referred to as energy-saving mode 1 and energy-saving mode 2, or energy-saving configuration 1 and energy-saving configuration 2. This application does not specifically limit the names of these two energy-saving technologies.

[0135] It should also be noted that in the embodiments of the present application, DTX technology and DRX technology can be collectively referred to as discontinuous transmission technology. In other words, DTX and DRX can be collectively referred to as discontinuous transmission, and the discontinuous transmission of a cell in the embodiments of the present application is DTX of the cell or DRX of the cell. In other words, in the embodiments of the application, discontinuous transmission is equivalent to DTX or DRX.

[0136] (2) DTX and DRX cycles, active periods, and inactive periods

[0137] The key configuration information of DTX / DRX may include the following items: cycle length, active period, inactive period, start time, and shut down time. Among them, the start time refers to the start time of the active time in the DTX / DRX cycle (that is, the start time of the DTX / DRX cycle), and the shut down time refers to the start time of the inactive time in the DTX / DRX cycle. The DTX / DRX cycle consists of an active period and an inactive period.

[0138] For example, see Figure 2 , Figure 2 This is a schematic diagram of the DTX / DRX cycle provided by this application. Figure 2 As shown, the DTX / DRX cycle includes an active period and an inactive period, and the total duration of the active period and the inactive period is the length of the DTX / DRX cycle. In addition, within a DTX / DRX cycle, the active period and the inactive time are included in chronological order.

[0139] It should be noted that in the embodiment of the present application, the active period in the DTX cycle is defined by the active timer of the DTX, and the active period of the DTX is the timing period (or running period) of the active timer of the DTX. The active period in the DRX cycle is defined by the active timer of the DRX, and the active period of the DRX is the timing period of the active timer of the DRX. It can also be understood that the starting time unit of the active period of the discontinuous transmission provided by the present application is the time unit where the timing start moment of the active timer corresponding to the discontinuous transmission is located, and the ending time unit of the active period of the discontinuous transmission is the time unit where the timing end moment or timeout moment of the active timer corresponding to the discontinuous transmission is located. The next time unit of the ending time unit of the active period of the DTX / DRX is the starting time unit of the DTX / DRX inactive period. Among them, the active timer of the DTX can also be called the cell DTX-on Duration Timer, and the active timer of the DRX can also be called the cellDRX-on Duration Timer. Correspondingly, the inactive period in the DTX / DRX cycle is the remaining period of the DTX / DRX cycle excluding the active period of the DTX / DRX.

[0140] In practical applications, the channel / signal that cannot be transmitted during the inactive period in the DTX cycle may be a downlink channel / signal, and the channel / signal that cannot be transmitted during the inactive period in the DRX cycle may be an uplink channel / signal.

[0141] Exemplarily, the channels / signals that cannot be transmitted during the inactive period within the DRX cycle include at least one of the following: configured grant PUSCH (CG PUSCH; PUSCH is the English abbreviation of physical uplink shared channel); hybrid automatic repeat request feedback (hybrid automatic repeat request-acknowledge, HARQ-ACK) of semi-persistent scheduled physical downlink shared channel (SPS PDSCH); scheduling request (scheduling request, SR); physical random access channel (physical random access channel, PRACH); random access message A; random access message 3.

[0142] Exemplarily, the channels / signals that cannot be transmitted during the inactive period of the DTX cycle include at least one of the following: PDCCH scrambled by modulation and coding scheme-cell-RNTI (MCS-C-RNTI); PDCCH scrambled by power saving-RNTI (PS-RNTI); PDCCH scrambled by system information-RNTI (SI-RNTI); PDCCH scrambled by random access-RNTI (RA-RNTI); PDCCH scrambled by temporary cell-RNTI (TC-RNTI); PDCCH scrambled by paging-RNTI (P-RNTI); PDCCH scrambled by paging advance indication wireless network temporary identifier (paging-RNTI, P-RNTI); PDCCH scrambled with early indication-RNTI, PEI-RNTI); synchronization and physical broadcast channel block SSB; system information; paging message; random access message 2; random access message 4; random access message B; or semi-persistent scheduling physical layer downlink shared channel (SPS PDSCH).

[0143] (3) Time unit

[0144] The time unit involved in this application is specifically the time domain resource granularity at a specific moment. Specifically, the time unit can be an orthogonal frequency division multiplexing (OFDM) symbol, a time slot (i.e., a slot), a millisecond or a second, etc., and this application does not impose any specific restrictions on this.

[0145] In the prior art, the network device instructs the terminal device to activate / deactivate cell DTX and cell DRX through multicast DCI. Since multicast DCI generally does not have a HARQ-ACK mechanism, when the terminal device cannot receive the multicast DCI, the terminal device and the network device cannot consistently activate / deactivate the DTX / DRX of the cell, which will seriously affect the transmission performance of the communication system.

[0146] Therefore, the technical problem to be solved by the present application is: when the terminal device cannot receive the indication information for indicating the discontinuous transmission of the activation / deactivation cell, how to reduce the damage to the transmission performance of the communication system caused by the discontinuous transmission of the activation / deactivation cell that the terminal device and the network device cannot consistently transmit.

[0147] Embodiment 1

[0148] To solve the above problems, the present application provides a communication method applicable to a terminal device. In the communication method, when the terminal device determines that the indication information for indicating the discontinuous transmission of activating / deactivating a certain cell is not detected, the terminal device will not transmit the first preset signal / channel in the set target time period, and / or transmit the second preset signal / channel in the set target time period. In the above implementation, it is specified how to transmit the first preset signal / channel and / or the second preset channel when the terminal device detects but does not receive the indication information for indicating the discontinuous transmission of activating / deactivating a certain cell, so that the transmission performance of the communication system caused by the discontinuous transmission of the activation / deactivation cell that the terminal device and the network device cannot consistently activate / deactivate can be reduced, and the transmission performance of the communication system can be made more stable and reliable.

[0149] In order to make the purpose, technical solution and advantages of the present application more clear, the present application will be further described in detail below in conjunction with the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment.

[0150] See also Figure 3 , Figure 3 1 is a flow chart of a communication method provided by the present application. The communication method is applicable to the terminal device described above. It should be noted that since the terminal device will perform a partial or full cycle of discontinuous transmission configured in a certain cell, Figure 3 For the convenience of understanding, the present embodiment of the present application takes the current period of the target discontinuous transmission of the first cell as an example to describe the various method steps to be performed by the terminal device. Figure 3 As shown, the method comprises the steps of:

[0151] S301, the terminal device detects target indication information sent by the network device.

[0152] In some feasible implementations, the terminal device detects the target indication information sent by the network device at a preset detection opportunity within the current cycle of the target discontinuous transmission of the first cell. The target indication information is used to instruct the terminal device to activate / deactivate the target discontinuous transmission of the first cell. The target discontinuous transmission can be the DTX of the first cell or the DRX of the first cell.

[0153] It should be understood that one or more detection opportunities can be preset within a period of target non-continuous transmission, and the terminal device will detect and receive the target indication information sent by the network device at this one or more detection opportunities. A detection opportunity is actually a period of time used by a terminal device to detect target indication information, which is usually determined by the terminal's search space (i.e., Searchspace) and control resource set (i.e., CORESET). Among them, the search space mainly specifies the period of occurrence of the detection opportunity, the number of time slots that the detection opportunity lasts in each period, the OFDM symbol position at which the detection opportunity starts in each time slot, and the number of PDCCH candidates at different aggregation levels. The control resource set mainly specifies the number of OFDM symbols that the detection opportunity lasts, the frequency domain resources corresponding to the detection opportunity, the interleaving and precoding methods used, etc. For example, please refer to Figure 4 , Figure 4 Schematic diagram of a detection timing of target discontinuous transmission provided by this application. Figure 4 As shown, the detection opportunity for the terminal device to detect the target indication information is preset in the current period of the target discontinuous transmission. It should be understood that Figure 4 Only one detection opportunity in the current cycle of the target discontinuous transmission is shown as an example. In actual implementation, there may be multiple detection opportunities.

[0154] Preferably, one or more detection opportunities in the current cycle of the target discontinuous transmission may all be located in the active period of the current cycle of the target discontinuous transmission. Figure 4 As shown, the detection opportunity in the current cycle of the target discontinuous transmission is located in the active period of the current cycle of the target discontinuous transmission.

[0155] In a specific implementation, the terminal device will detect the signaling used to carry the target indication information at the detection opportunity within the current cycle of the target non-continuous transmission. Optionally, in an embodiment of the present application, the signaling used to carry the target indication information may be a multicast DCI or a MAC CE. That is, the terminal device may detect the multicast DCI or MAC CE carrying the target indication information at the detection opportunity within the current cycle of the target non-continuous transmission. It can be understood that in actual implementation, the network device may also use other possible signaling to transmit the target indication information, and the terminal device may also receive the above-mentioned target indication information by detecting these possible signaling. The present application does not impose specific restrictions on the method of transmitting the target indication information between the network device and the terminal device.

[0156] S302: If the terminal device determines that the target indication information is not detected, the first preset signal / channel is not transmitted in the target time period, and / or the second preset signal / channel is transmitted in the target time period.

[0157] In some feasible implementations, if the terminal device determines that it has not detected the target indication information sent by the network device, the first preset signal / channel may not be transmitted during the set target time period. Alternatively, if the terminal device determines that it has not detected the target indication information sent by the network device, the second preset signal / channel may be transmitted during the set target time period. Alternatively, if the terminal device determines that it has detected the target indication information sent by the network device, the first preset signal / channel may not be transmitted during the set target time period, and the second preset signal / channel may be transmitted during the target time period. It can also be understood that, when the terminal device determines that the target indication information is not detected, it may transmit the first preset signal / channel during the target time period in a manner that activates the target discontinuous transmission, and / or transmit the second preset signal / channel in a manner that deactivates the target discontinuous transmission.

[0158] In an optional implementation, the target period may be an inactive period in the current cycle of the target discontinuous transmission of the first cell. Alternatively, the target period may be an inactive period in Y cycles after the current cycle of the target discontinuous transmission of the first cell. For example, assuming that Y is equal to 1, the target period may be an inactive period in the next cycle of the current cycle of the target discontinuous transmission of the first cell. Alternatively, the target period may be an inactive period in the current cycle of the target discontinuous transmission of the first cell and an inactive period in Y cycles after the current cycle.

[0159] In an optional implementation, the target time period may be an inactive time period of the target discontinuous transmission included in a preset target cycle, or it may be understood that the target time period is an inactive time period included in the target discontinuous transmission and located within the target cycle. Here, the target period is different from the period of the search space indication associated with the target indication information. It should be noted that, in the case where the target indication information includes a multicast DCI, the period of the search space indication associated with the target indication information refers to the period configuration indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration corresponding to the multicast DCI. Specifically, the parameter indicates the period length and the starting time slot offset of the period. The target period is different from the period of the search space indication associated with the target indication information, which means that the period configuration corresponding to the target period exists independently of the period configuration of the search space indication corresponding to the multicast DCI. In other words, the period length of the target period is different from the period length indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI, and / or the period start offset of the target period is different from the period start offset indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI.

[0160] Further, the target period may be a positive integer multiple of the period of the target discontinuous transmission of the first cell.

[0161] In an optional implementation, the target discontinuous transmission is the DTX of the first cell, that is, the first cell of the terminal device is configured with DTX, and the target indication information is used to indicate activation / deactivation of the DTX of the first cell. In this case, the first preset signal / channel may include at least one of the following: a periodic CSI reference signal (P-CSI-RS) for channel state information (CSI) reporting, a semi-persistent CSI reference signal (SP-CSI-RS) for CSI reporting, a P-CSI-RS for radio link monitoring (RLM), an SP-CSI-RS for RLM, a P-CSI-RS for beam failure detection (BFD), an SP-CSI-RS for BFD, a P-CSI-RS for beam failure recovery (BFR), an SP-CSI-RS for BFR, a radio resource management (RFM) signal. management, RRM), SP-CSI-RS for RRM, P-CSI-RS for beam management (BM), SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, P-CSI-RS for positioning, SP-CSI-RS for positioning.

[0162] Among them, the P-CSI-RS used for CSI reporting can also be expressed as "P-CSI-RS for CSI reporting", and the SP-CSI-RS used for CSI reporting can also be expressed as "SP-CSI-RS for CSI reporting".

[0163] The P-CSI-RS for RLM may also be expressed as "P-CSI-RS forRLM", and the SP-CSI-RS for RLM may also be expressed as "SP-CSI-RS for RLM". Alternatively, the P / SP CSI-RS for RLM may also be expressed as "CSI-RS associated with RadioLinkMonitoringConfig or RadioLinkMonitoringRS".

[0164] The P-CSI-RS for BFD may also be expressed as "P-CSI-RS for BFD", and the SP-CSI-RS for BFD may also be expressed as "SP-CSI-RS for BFD". Alternatively, the P / SP CSI-RS for BFD may be expressed as "CSI-RS associated with BeamFailureRecoveryConfig or BeamFailureRecoveryRSConfig".

[0165] The P-CSI-RS for BFR can also be expressed as "P-CSI-RS for BFR", and the SP-CSI-RS for BFR can also be expressed as "SP-CSI-RS for BFD". Alternatively, the P / SP CSI-RS for BFR can be expressed as "CSI-RS associated with CandidateBeamRS".

[0166] The P-CSI-RS for RRM can also be expressed as "P-CSI-RS for RRM", and the SP-CSI-RS for RRM can also be expressed as "SP-CSI-RS for RRM". Alternatively, the P / SP CSI-RS for RRM can be expressed as "CSI-RS associated with MeasObjectNR, ReferenceSignalConfig or csi-rs-ResourceConfigMobility".

[0167] The P-CSI-RS for BM may also be expressed as "P-CSI-RS for BM", and the SP-CSI-RS for BM may also be expressed as "SP-CSI-RS for BM". Alternatively, the P / SP CSI-RS for BM may be expressed as "CSI-RS associated with CSI-reportconifg of the reporting configuration cri-RSRP / L1-RSRP / L1-SINR".

[0168] The P-CSI-RS used for tracking may also be expressed as "P-CSI-RS for tracking", and the SP-CSI-RS used for tracking may also be expressed as "SP-CSI-RS for tracking". Alternatively, the P / SP CSI-RS used for tracking may be expressed as "CSI-RS with TRS-info configured as true".

[0169] The P-CSI-RS used for positioning may also be expressed as “P-CSI-RS for positioning”, and the SP-CSI-RS used for positioning may also be expressed as “SP-CSI-RS for positioning”. Alternatively, the P / SP CSI-RS used for positioning may also be expressed as PRS (ie, positioning RS).

[0170] In an optional implementation, the target discontinuous transmission is DTX of the first cell, and the second preset signal / channel may include at least one of the following: a physical downlink control channel (PDCCH) scrambled by a cell radio network temporary identifier (C-RNTI), a PDCCH scrambled by a configured scheduling radio network temporary identifier (CS-RNTI), a PDCCH scrambled by a modulation and coding scheme cell radio network temporary identifier (MCS-C-RNTI), a PDCCH scrambled by an interrupt radio network temporary identifier (INT-RNTI), a PDCCH scrambled by a slot format indication radio network temporary identifier (SFI-RNTI), a PDCCH scrambled by an uplink shared channel power control radio network temporary identifier (PUSCH transmit power control radio network temporary identifier). identifier, TPC-PUSCH-RNTI), PDCCH scrambled by uplink control channel power control radio network temporary identifier (PUCCH transmit power control radio network temporary identifier, TPC-PUCCH-RNTI), PDCCH scrambled by channel sounding reference signal power control radio network temporary identifier (SRStransmit power control radio network temporary identifier, TPC-SRS-RNTI), PDCCH scrambled by cancellation indication radio network temporary identifier (cancellation indication radio network temporary identifier,CI-RNTI) scrambled PDCCH, PDCCH scrambled by availability indicator radio network temporary identifier (AI-RNTI), semi persistent scheduled physical downlink shared channel (SPS PDSCH).

[0171] Exemplarily, when the target time period is an inactive time period within the current cycle of the target non-continuous transmission of the first cell or an inactive time period within Y cycles after the current cycle and the first cell of the terminal device is configured with DTX, when the terminal device determines that the target indication information for indicating activation / deactivation of the DTX of the first cell is not detected, it will only detect (or receive) at least one of the following signals / channels within the active time period of the current cycle of the first DTX or within the active time period of Y cycles after the current cycle: periodic P-CSI-RS for CSI reporting, SP-CSI-R for CSI reporting S, P-CSI-RS for RLM, SP-CSI-RS for RLM, P-CSI-RS for BFD, SP-CSI-RS for BFD, P-CSI-RS for BFR, SP-CSI-RS for BFR, P-CSI-RS for RRM, SP-CSI-RS for RRM, P-CSI-RS for BM, SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, P-CSI-RS for positioning, SP-CSI-RS for positioning. It does not detect or receive at least one of the following downlink signals / channels during the inactive period of the current cycle of the first DTX or the inactive period of Y cycles after the current cycle: periodic P-CSI-RS for CSI reporting, SP-CSI-RS for CSI reporting, P-CSI-RS for RLM, SP-CSI-RS for RLM, P-CSI-RS for BFD, SP-CSI-RS for BFD, P-CSI-RS for BFR, SP-CSI-RS for BFR, P-CSI-RS for RRM, SP-CSI-RS for RRM, P-CSI-RS for BM, SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, P-CSI-RS for positioning, and SP-CSI-RS for positioning.

[0172] Alternatively, when the terminal device determines that the target indication information for indicating activation / deactivation of the DTX of the first cell is not detected, it will receive at least one of the following items sent by the network device during the inactive period of the current cycle of the first DTX or Y cycles after the current cycle: PDCCH scrambled by C-RNTI, PDCCH scrambled by CS-RNTI, PDCCH scrambled by interruption wireless network temporary identifier INT-RNTI, PDCCH scrambled by time slot format indication wireless network temporary identifier SFI-RNTI, PDCCH scrambled by uplink shared channel power control wireless network temporary identifier TPC-PUSCH-RNTI, PDCCH scrambled by uplink control channel power control wireless network temporary identifier TPC-PUCCH-RNTI, PDCCH scrambled by channel sounding reference signal power control wireless network temporary identifier TPC-SRS-RNTI, PDCCH scrambled by cancellation indication wireless network temporary identifier CI-RNTI, PDCCH scrambled by availability indication wireless network temporary identifier AI-RNTI, PDCCH scrambled by MCS-C-RNTI, SPS PDSCH.

[0173] Alternatively, when the terminal device determines that the target indication information for indicating activation / deactivation of the DTX of the first cell is not detected, it will detect (or receive) at least one of the following downlink signals / channels during the active period of the current cycle of the first DTX or the active period of Y cycles after the current cycle: periodic P-CSI-RS for CSI reporting, SP-CSI-RS for CSI reporting, P-CSI-RS for RLM, SP-CSI-RS for RLM, P-CSI-RS for BFD, SP-CSI-RS for BFD, P-CSI-RS for BFR, SP-CSI-RS for BFR, P-CSI-RS for RRM, SP-CSI-RS for RRM, P-CSI-RS for BM, SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, and P-CSI for positioning. -RS, SP-CSI-RS for positioning, which will also not detect or receive at least one of the following downlink signals / channels during the inactive period of the current cycle of the first DTX or the inactive period of Y cycles after the current cycle: periodic P-CSI-RS for CSI reporting, SP-CSI-RS for CSI reporting, P-CSI-RS for RLM, SP-CSI-RS for RLM, P-CSI-RS for BFD, SP-CSI-RS for BFD, P-CSI-RS for BFR, SP-CSI-RS for BFR, P-CSI-RS for RRM, SP-CSI-RS for RRM, P-CSI-RS for BM, SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, P-CSI-RS for positioning, SP-CSI-RS for positioning.It will also send at least one of the following to the network device during the inactive period of the current cycle of the first DTX or Y cycles after the current cycle: PDCCH scrambled by C-RNTI, PDCCH scrambled by CS-RNTI, PDCCH scrambled by MCS-C-RNTI, PDCCH scrambled by interruption wireless network temporary identifier INT-RNTI, PDCCH scrambled by time slot format indication wireless network temporary identifier SFI-RNTI, PDCCH scrambled by uplink shared channel power control wireless network temporary identifier TPC-PUSCH-RNTI, PDCCH scrambled by uplink control channel power control wireless network temporary identifier TPC-PUCCH-RNTI, PDCCH scrambled by channel sounding reference signal power control wireless network temporary identifier TPC-SRS-RNTI, PDCCH scrambled by cancellation indication wireless network temporary identifier CI-RNTI, PDCCH SPS PDSCH scrambled by availability indication wireless network temporary identifier AI-RNTI.

[0174] In the above implementation, when the first cell of the terminal device is configured with DTX, it is specified how to transmit the preset first preset signal / channel, and / or, the second preset signal / channel when the terminal device does not receive the target indication information for indicating the activation / deactivation of DTX of the first cell, and further defines which signals and / or channels the first preset signal / channel, and / or, the second preset signal / channel specifically include. The limitation on the first preset signal / channel can prevent the terminal device from receiving such signals / channels during inactive periods, thereby ensuring the accuracy of the measurement results of the terminal device and reducing the adverse effects on link performance. The limitation on the second preset signal / channel can enable the terminal device to receive such signals / channels during inactive periods of DTX, thereby reducing the adverse effects on the transmission performance of such signals / channels. In this way, the transmission performance of the communication system may be damaged due to the inability of the terminal device and the network device to consistently activate / deactivate the first DTX of the first cell, thereby improving the transmission reliability of the communication system.

[0175] Optionally, the first cell is also configured with at least one second DTX. In this case, the target indication information can be used to instruct the terminal device to activate / deactivate the first DTX and at least one second DTX of the first cell. The period of the first DTX should be longer than or equal to the period of each second DTX in the at least one second DTX. Alternatively, the active period of the first DTX should be shorter than or equal to the active period of each second DTX. Alternatively, the period of the first DTX should be longer than or equal to the period of each second DTX in the at least one second DTX and the active period of the first DTX should be shorter than or equal to the active period of each second DTX.

[0176] That is to say, in the case where the first cell is configured with the first DTX and at least one second DTX, if the terminal device determines that the target indication information for indicating activation / deactivation of the first cell and the at least one second DTX is not detected, then the DTX with the longest cycle and / or the shortest active period can be determined from the above-mentioned first DTX and the at least one second DTX (for the convenience of distinction, the target DTX is used instead of the expression hereinafter), and the first preset signal / channel mentioned above is not transmitted during the inactive period of the current cycle of the target DTX or Y cycles after the current cycle, and / or the second preset signal / channel is transmitted during the inactive period of the current cycle of the target DTX or Y cycles after the current cycle. It can also be understood that, in the case where the first cell of the terminal device is configured with multiple DTXs, if the terminal device determines that the target indication information is not detected, the first preset signal / channel mentioned above can be transmitted in a manner that the DTX with the longest cycle and / or the shortest active period is activated, and the second preset signal / channel mentioned above can be transmitted in a manner that the DTX with the longest cycle and / or the shortest active period is deactivated.

[0177] Alternatively, if the terminal device determines that the target indication information for indicating the activation / deactivation of the first DTX and at least one second DTX of the first cell is not detected, the target DTX with the longest period and / or the shortest active period may be determined among the above-mentioned first DTX and at least one second DTX, and the first preset signal / channel mentioned above may not be transmitted during the inactive period of the target discontinuous transmission of the target DTX included in the target period, and / or the second preset signal / channel may be transmitted during the inactive period of the target discontinuous transmission of the target DTX included in the target period.

[0178] In the above implementation, when the first cell of the terminal device is configured with multiple DTXs, it is clarified that the terminal device transmits the first preset signal / channel mentioned above in accordance with which DTX is activated, and transmits the second preset signal / channel mentioned above in accordance with which DTX is deactivated. This can effectively solve the problem of how to reduce the damage to the transmission performance of the communication system when the first cell is configured with multiple DTXs.

[0179] Optionally, when the terminal device fails to detect the target indication information and determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DTX of the first cell or Y cycles after the current cycle in accordance with the first DTX activation mode, after it obtains the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel, if it is determined that the first transmission resource partially overlaps with the active period of the above-mentioned first DTX in the time domain, then the above-mentioned first preset signal / channel, and / or, the above-mentioned second preset signal / channel may be transmitted on the first transmission resource. That is to say, even if the terminal device determines to deactivate the first preset signal / channel in accordance with the first DTX in the current cycle of the first DTX or Y cycles after the current cycle, when it determines that the first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active period of the above-mentioned first DTX in the time domain, then the above-mentioned first preset signal / channel, and / or, the above-mentioned second preset signal / channel will still be transmitted on the first transmission resource.

[0180] For example, see Figure 5 , Figure 5 This is a transmission resource diagram provided by this application. Figure 5 As shown, the terminal device determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DTX of the first cell in accordance with the first DTX activation mode, and the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active time period in the current cycle of the first DTX in the time domain, that is, the time period corresponding to the first transmission resource partially overlaps with the active time period in the current cycle of the first DTX, the terminal device will still transmit the above-mentioned first preset signal / channel, and / or, the second preset signal / channel on the first transmission resource.

[0181] The above implementation method solves the problem of how to transmit the first preset signal / channel, and / or the second preset signal / channel when the first transmission resource corresponding to the first preset signal / channel and / or the second preset signal / channel conflicts with the active period of the first DTX understood as an activated state, thereby avoiding leakage of the first preset signal / channel and / or the second preset signal / channel.

[0182] In another optional implementation, the target discontinuous transmission is the DRX of the first cell, that is, the first cell of the terminal device is configured with DRX, and the target indication information is used to indicate activation / deactivation of the DRX of the first cell. In this case, the first preset signal / channel may include at least one of the following: a configured authorized physical uplink shared channel (configured grant PUSCH, CG PUSCH), (scheduling request, SR).

[0183] Optionally, the above-mentioned SR may include a scheduling request SR with a physical layer priority index configured as 0, and / or an SR associated with a logical channel with a low priority at the MAC layer. Among them, the SR with a physical layer priority index configured as 0 can be expressed as "SR with the phy-PriorityIndex-r16 field configured as p0", "SR with the physical layer priority configured as 0" or "SR with a low priority at the physical layer". Here, a low-priority logical channel refers to a logical channel with a larger MAC layer parameter priority configuration value when multiple logical channels are associated with the SR configuration, or a logical channel with a priority configuration value less than or equal to s. s is a positive integer. For example, assuming there are three logical channels with corresponding MAC priorities of 1, 5, and 10, respectively, the logical channels with a priority of 10, or priorities of 5 and 10 are considered to be logical channels with a low priority at the MAC layer.

[0184] In another optional implementation, the target discontinuous transmission is the DRX of the first cell, and the second preset signal / channel may include at least one of the following: P-SRS for positioning function, SP-SRS for positioning function, P-SRS other than for positioning function, SP-SRS other than for positioning function, HARQ-ACK associated with SPS PDSCH, periodic channel state information (periodic CSI, P-CSI), semi-persistent channel state information (semi-persistent CSI, SP-CSI). Among them, the P-SRS for positioning function can also be expressed as "P-SRS for positioning", the SP-SRS for positioning function can also be expressed as "SP-SRS for positioning", and the HARQ-ACK associated with SPS PDSCH can also be expressed as "ACK for SPS PDSCH".

[0185] That is to say, in the case where the first cell of the terminal device is configured with the first DRX, when the terminal device determines that the target indication information for indicating activation / deactivation of the first DRX is not detected, it will only send at least one of the following uplink signals / channels to the network device during the active period of the current cycle of the first DRX or during the active period of Y cycles after the current cycle: CG PUSCH, SR. It does not detect or receive at least one of the following uplink signals / channels during the inactive period of the current cycle of the first DRX or during the inactive period of Y cycles after the current cycle: CGPUSCH, SR.

[0186] Alternatively, when the terminal device determines that the target indication information for indicating activation / deactivation of the DRX of the first cell is not detected, it will send at least one of the following downlink signals / channels to the network device during the inactive period of the current cycle of the first DRX or Y cycles after the current cycle: P-SRS for positioning function, SP-SRS for positioning function, P-SRS other than used for positioning function, SP-SRS other than used for positioning function, SPS PDSCH associated HARQ-ACK, P-CSI, SP-CSI.

[0187] Alternatively, when the terminal device determines that the target indication information for indicating activation / deactivation of the DRX of the first cell is not detected, it will only send at least one of the following uplink signals / channels to the network device during the active period of the current cycle of the first DRX or during the active period of Y cycles after the current cycle: CG PUSCH, SR with a physical layer priority index configured as 0, SR associated with a logical channel with a low priority at the MAC layer. It does not detect or receive at least one of the following uplink signals / channels during the inactive period of the current cycle of the first DRX or during the inactive period of Y cycles after the current cycle: CG PUSCH, SR with a physical layer priority index configured as 0, SR associated with a logical channel with a low priority at the MAC layer. It will also receive at least one of the following downlink signals / channels sent by the network device during the inactive period of the current cycle of the first DRX or Y cycles after the current cycle: P-SRS for positioning function, SP-SRS for positioning function, P-SRS other than used for positioning function, SP-SRS other than used for positioning function, HARQ-ACK associated with SPS PDSCH, P-CSI, and SP-CSI.

[0188] In the above implementation, when the first cell of the terminal device is configured with DRX, it is specified how to transmit the preset first preset signal / channel, and / or, the second preset signal / channel when the terminal device does not receive the target indication information for indicating the activation / deactivation of the DRX of the first cell, and further defines which channels and / or signals the first preset signal / channel, and / or, the second preset signal / channel specifically include. The limitation on the first preset signal / channel can prevent the terminal device from sending such signals / channels during the inactive period of DRX, ensuring that the network device can correctly receive such uplink transmissions, and reducing the adverse effects on link performance. The limitation on the second preset signal / channel can prevent the terminal device from sending such signals / channels during the inactive period of DRX, ensuring that the network device can receive such transmissions, and reducing the adverse effects on link performance. This can effectively reduce the problem of impaired transmission performance of the communication system caused by the inability of the terminal device and the network device to consistently activate / deactivate the first DRX of the first cell, and can improve the transmission reliability of the communication system.

[0189] Optionally, the first cell is also configured with at least one second DRX. In this case, the target indication information can be used to instruct the terminal device to activate / deactivate the first DRX and at least one second DRX of the first cell. The cycle of the first DRX should be longer than or equal to the cycle of each second DRX in the at least one second DRX. Alternatively, the active period of the first DRX should be shorter than or equal to the active period of each second DRX. Alternatively, the cycle of the first DRX should be longer than or equal to the cycle of each second DRX in the at least one second DRX and the active period of the first DRX should be shorter than or equal to the active period of each second DRX.

[0190] That is to say, in the case where the first cell is configured with the first DRX and at least one second DRX, if the terminal device determines that the target indication information for indicating activation / deactivation of the first DRX and at least one second DRX of the first cell is not detected, the DRX with the longest cycle and / or the shortest active period can be determined from the above-mentioned first row DRX and at least one second DRX (hereinafter referred to as the target DRX for the convenience of distinction), and the first preset signal / channel mentioned above is not transmitted during the inactive period of the current cycle of the target DRX or Y cycles after the current cycle, and / or the second preset signal / channel is transmitted during the inactive period of the current cycle of the target DRX or Y cycles after the current cycle. It can also be understood that, in the case where the first cell of the terminal device is configured with multiple DRXs, if the terminal device determines that the target indication information is not detected, the first preset signal / channel mentioned above can be transmitted in a manner that the DRX with the longest cycle and / or the shortest active period is activated, and the second preset signal / channel mentioned above can be transmitted in a manner that the DRX with the longest cycle and / or the shortest active period is deactivated.

[0191] Alternatively, if the terminal device determines that the target indication information for indicating the activation / deactivation of the first DRX and at least one second DRX of the first cell is not detected, the target DRX with the longest cycle and / or the shortest active period can be determined among the above-mentioned first DRX and at least one second DRX, and the first preset signal / channel mentioned above shall not be transmitted during the inactive period of the target discontinuous transmission of the target DRX included in the target cycle, and / or the second preset signal / channel shall be transmitted during the inactive period of the target discontinuous transmission of the target DRX included in the target cycle.

[0192] In the above implementation, when the first cell of the terminal device is configured with multiple DRXs, it is clarified that the terminal device transmits the first preset signal / channel mentioned above in accordance with which DRX is activated. This can effectively solve the problem of how to reduce the damage to the transmission performance of the communication system when the first cell is configured with multiple DRXs.

[0193] Optionally, when the terminal device does not detect the target indication information and determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DRX of the first cell or Y cycles after the current cycle in accordance with the first DRX activation mode, after it obtains the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel, if it is determined that the first transmission resource partially overlaps with the active period of the above-mentioned first DRX in the time domain, then the above-mentioned first preset signal / channel and / or, the above-mentioned second preset signal / channel may be transmitted on the first transmission resource. That is to say, even if the terminal device determines to deactivate the first preset signal / channel in accordance with the first DRX in the current cycle of the first DRX or Y cycles after the current cycle, when it determines that the first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active period of the above-mentioned first DRX in the time domain, then the above-mentioned first preset signal / channel and / or, the above-mentioned second preset signal / channel will still be transmitted on the first transmission resource.

[0194] For example, see Figure 6 , Figure 6 This is another transmission resource diagram provided by this application. Figure 6 As shown, the terminal device determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DRX of the first cell in accordance with the first DRX activation mode, and the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active period in the current cycle of the first DRX in the time domain, that is, the time period corresponding to the first transmission resource partially overlaps with the active period in the current cycle of the first DRX, the terminal device will still transmit the above-mentioned first preset signal / channel, and / or, the second preset signal / channel on the first transmission resource.

[0195] The above implementation method solves the problem of how to transmit the first preset signal / channel, and / or the second preset signal / channel when the first transmission resource corresponding to the first preset signal / channel and / or the second preset signal / channel conflicts with the active period of the first DRX understood to be in an activated state, thereby avoiding leakage of the first preset signal / channel and / or the second preset signal / channel.

[0196] In another optional implementation, when the first cell and each of the at least one second cell of the terminal device are configured with target discontinuous transmission, and the target discontinuous transmission of the first cell has the shortest active period / shortest cycle among the multiple cells, the terminal device detects the target indication information only within the detection period of the target continuous transmission of the first cell, and the target indication information can simultaneously indicate the activation / deactivation of the target discontinuous transmission of the first cell and each of the at least one second cell. In this case, for any one of the at least one second cell mentioned above (here assumed to be the second cell i), when multiple detection opportunities for the target indication information defined based on the first cell fall within a certain cycle of the second cell i, if the terminal device does not receive the target indication information at at least one detection time among the multiple detection opportunities, the terminal device can determine that it has not detected the target indication information for the second cell i. For example, please refer to Figure 7 , Figure 7 FIG. 1 is another schematic diagram of a detection timing of a target discontinuous transmission provided by the present application. Figure 7 As shown, the detection timing of the target indication information is defined by the first cell, and the first period, second period and third period of the target discontinuous transmission of the first cell respectively have detection timing 1, detection timing 2 and detection timing 3 of the target indication information, and detection timing 1, detection timing 2 and detection timing 3 are also located in the first period of the second cell i. In this case, if the terminal device determines that the target indication information is not detected at any one or more of the above detection timing 1, detection timing 2 and detection timing 3, it is determined that it has not detected the target indication information corresponding to the target discontinuous transmission of the second cell i.

[0197] Further, the terminal device may not transmit the first preset signal / channel mentioned above during the inactive period of the current cycle of the target discontinuous transmission of the second cell i or the inactive period of Y cycles after the current cycle. Alternatively, the terminal device may transmit the second preset signal / channel during the inactive period of the current cycle of the target discontinuous transmission of the second cell i or the Y cycles after the current cycle. Alternatively, the terminal device may not transmit the first preset signal / channel during the inactive period of the current cycle of the target discontinuous transmission of the second cell i or the Y cycles after the current cycle, and transmit the second preset signal / channel during the inactive period of the current cycle of the target discontinuous transmission of the second cell i or the Y cycles after the current cycle. It can also be understood that the terminal device transmits the first preset signal / channel in a manner of activating the target discontinuous transmission and / or transmits the second preset signal / channel in a manner of deactivating the target discontinuous transmission during the current cycle of the target discontinuous transmission of the second cell i or the Y cycles after the current cycle.

[0198] Alternatively, the terminal device may not transmit the first preset signal / channel mentioned above during the inactive period of the target discontinuous transmission of the second cell i included in the target period, and / or transmit the second preset signal / channel during the inactive period of the target discontinuous transmission of the second cell i included in the target period.

[0199] In some feasible implementations, when the target period is an inactive period of target discontinuous transmission included in a preset target period, the terminal device may receive the period configuration information corresponding to the target period sent by the network device. The period configuration information includes at least the period length and starting offset of the target period. Further, the terminal device may determine the above target period based on the period length and starting offset of the target period. For example, assuming that the period length of the target period is 80ms and the starting offset is 20ms, the terminal device may determine that the starting time of the target period is 20ms, 100ms, 180ms, 260ms, etc.

[0200] Correspondingly, in this case, the network device may also generate and send to the terminal device the period configuration information corresponding to the target period, so that the terminal device can determine the target period based on the period configuration information.

[0201] In this embodiment, it is specified how to transmit the first preset signal / channel and / or the second preset channel when the terminal device detects but does not receive the indication information for indicating the activation / deactivation of the discontinuous transmission of a certain cell. This can reduce the damage to the transmission performance of the communication system caused by the discontinuous transmission of the cell that the terminal device and the network device cannot consistently activate / deactivate, and make the transmission performance of the communication system more stable and reliable.

[0202] Embodiment 2

[0203] To solve the above problems, the present application provides a communication method applicable to terminal devices and network devices. In the communication method, when the terminal device or the network device determines that a preset target event occurs, the target discontinuous transmission is kept activated / deactivated within the target period. Alternatively, the target discontinuous transmission is deactivated within the target period. Alternatively, the first preset signal / channel is not transmitted during the target time period, and / or the second preset signal / channel is transmitted during the target time period. Since the occurrence of the target event will result in the inability to transmit the target indication information for indicating the activation / deactivation of the target discontinuous transmission of the first cell between the terminal device and the network device, the communication method provided in this embodiment specifies the specific behavior of the terminal device and the network device when the target event occurs, which can also reduce the problem of impaired transmission performance of the communication system caused by the discontinuous transmission of the cell that the terminal device and the network device cannot consistently activate / deactivate.

[0204] See also Figure 8 , Figure 8 is a flow chart of another communication method provided by the present application. The communication method is applicable to the terminal device and the network device described above. It should be noted that, since the communication method is executed in the same process on the terminal device and the network device, in order to facilitate understanding, the terminal device and the network device are collectively referred to as the target device in the second embodiment. In addition, since the terminal device or the network device will execute on part or all of the cycles of the discontinuous transmission configured in a certain cell Figure 8 For the convenience of understanding, the communication method shown in the second embodiment takes the current period of the target discontinuous transmission of the first cell as an example to describe the various steps of the communication method. Figure 8 As shown, the method comprises the steps of:

[0205] S801: A target device determines that a target event occurs.

[0206] In some feasible implementations, the target device may detect whether a preset target event occurs within the current cycle of the target discontinuous transmission of the first cell. If it is determined that the target event occurs, the following step S802 may be performed. If the target device determines that the target event does not occur, when the target device is a terminal device, the target indication information for indicating activation / deactivation of the target discontinuous transmission of the first cell may continue to be detected at the detection opportunity preset for the target discontinuous transmission. When the target device is a network device, it may send the above-mentioned target indication information to the terminal device at the detection opportunity preset for the target discontinuous transmission. It should be understood that one or more detection opportunities may be preset within a cycle of the target discontinuous transmission, and the terminal device may detect and receive the target indication information at these one or more detection opportunities, and the network device may also send the target indication information at these one or more detection opportunities. It should be understood that a detection opportunity is actually a period of time for a terminal device to detect the target indication information, which is usually determined by the search space (i.e., Searchspace) and the control resource set (i.e., CORESET) of the terminal. The search space mainly specifies the period of detection opportunities, the number of time slots that detection opportunities last in each period, the OFDM symbol position where detection opportunities start in each time slot, and the number of PDCCH candidates at different aggregation levels. The control resource set mainly specifies the number of OFDM symbols that detection opportunities last, the frequency domain resources corresponding to detection opportunities, the interleaving and precoding methods used, etc.

[0207] Furthermore, the above-mentioned target event includes at least one of the following: all detection opportunities of the above-mentioned target indication information are in the measurement interval, all detection opportunities of the target indication information are in the running period of the random access contention resolution timer ra-ContentionResolutionTimer, all detection opportunities of the target indication information are in the running period of the message B response window msgB-ResponseWindow, all detection opportunities of the target indication information are in the running period of the random response window ra-ResponseWindow, all detection opportunities of the target indication information are in the partial bandwidth BWP switching process, all detection opportunities of the target indication information are in the beam failure recovery BFR process, the terminal device is in the first detection opportunity before the starting time unit of the last detection opportunity of the target indication information A scheduling request SR is sent on X time units, in the current cycle, the terminal device performs uplink data scheduling on the Xth time unit before the start time unit of the last detection opportunity of the target indication information, in the current cycle of target discontinuous transmission, the terminal device performs downlink data scheduling on the Xth time unit before the start time unit of the last detection opportunity of the target indication information, all detection opportunities of the target indication information are in the operation period of the discontinuous reception downlink retransmission timer drx-RetransmissionTimerDL, all detection opportunities of the target indication information are in the operation period of the discontinuous reception uplink retransmission timer drx-RetransmissionTimerUL, and all detection opportunities of the target indication information are in the period when the terminal device makes an emergency call. Wherein, X is a positive integer greater than or equal to 1. For example, X can be equal to 4, and the above time unit is ms, then the target event can be that the terminal device performs uplink data scheduling 4ms before the start time of the last detection opportunity of the target indication information.

[0208] It should be understood that the terminal device sends a scheduling request SR at the Xth time unit before the start time unit of the last detection opportunity of the target indication information, which can also be understood as there is an SR in the pending state, or the SR-prohibittimer is running. The so-called uplink or downlink scheduling is to send a PDCCH that schedules specific data transmission, or to send a PDSCH / PUSCH that schedules specific data transmission. All detection opportunities of the target indication information are in the beam failure recovery BFR process, which can also be expressed as all detection opportunities of the target indication information are in the running period of the beam failure recovery timer beamFailureRecoveryTimer. All detection opportunities of the target indication information are in the beam failure recovery process, which can also be expressed as all detection opportunities are in the period when the terminal device is detecting the C-RNTI-encrypted PDCCH in the search space configured in the recoverySearchSpaceId corresponding to the SpCell, and the ra-ResponseWindow is running.

[0209] It should also be understood that all detection opportunities of the target indication information mentioned in the above items refer to all detection opportunities preset within the period of the target discontinuous transmission of the first cell.

[0210] S802. The target device maintains the target discontinuous transmission activation / deactivation of the first cell within the target period, or the target device deactivates the target discontinuous transmission of the first cell within the target period, or the target device does not transmit the first preset signal / channel in the target time period, and / or transmits the second preset signal / channel in the target time period.

[0211] In some feasible implementations, when the target device determines that the above target event occurs within the target discontinuous transmission period of the first cell, one of the following three actions may be taken.

[0212] The first behavior is to maintain the target discontinuous transmission activation / deactivation of the first cell within the target period.

[0213] Optionally, the target period may be a current period of target discontinuous transmission of the first cell, and / or Y periods after the current period, where Y is a positive integer greater than or equal to 1.

[0214] That is, when the target device determines that the target event occurs, if the target device determines that the target discontinuous transmission of the first cell is activated in the previous cycle of its current cycle, it can be determined that the target discontinuous transmission of the first cell is also activated in the current cycle or Y cycles after the current cycle. Correspondingly, if the target device determines that the target discontinuous transmission of the first cell is deactivated in the previous cycle of its current cycle, it can be determined that the target discontinuous transmission of the first cell is also deactivated in the current cycle or Y cycles after the current cycle.

[0215] Optionally, the target period is a preset period, and is different from the period of the search space indication associated with the target indication information for activating / deactivating the target non-continuous transmission of the first cell. It should be noted that, when the target indication information includes multicast DCI, the period of the search space indication associated with the target indication information refers to the period configuration indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration corresponding to the multicast DCI. Specifically, the parameter indicates the period length and the starting time slot offset of the period. The target period is different from the period of the search space indication associated with the target indication information, which means that the period configuration corresponding to the target period exists independently of the period configuration of the search space indication corresponding to the multicast DCI. In other words, the period length of the target period is different from the period length indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI, and / or the period start offset of the target period is different from the period start offset indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI.

[0216] That is, when the target device determines that the target event occurs, if the target device determines that the target discontinuous transmission of the first cell is activated in the previous cycle of its current cycle, it can be determined that the target discontinuous transmission of the first cell is also activated in a target cycle different from the cycle indicated by the search space associated with the target indication information used to activate / deactivate the target discontinuous transmission of the first cell. Correspondingly, if the target device determines that the target discontinuous transmission of the first cell is deactivated in the previous cycle of its current cycle, it can be determined that the target discontinuous transmission of the first cell is also deactivated in a target cycle different from the cycle indicated by the search space associated with the target indication information used to activate / deactivate the target discontinuous transmission of the first cell.

[0217] The second behavior is to deactivate the target discontinuous transmission of the first cell within the target period.

[0218] Optionally, the target period may be a current period of target discontinuous transmission of the first cell, and / or Y periods after the current period, where Y is a positive integer greater than or equal to 1.

[0219] That is, when the target device determines that the target event occurs, it determines to deactivate the target discontinuous transmission of the first cell within the current cycle or Y cycles after the current cycle.

[0220] Optionally, the target period is a preset period, and is different from the period of the search space indication associated with the target indication information for activating / deactivating the target non-continuous transmission of the first cell. It should be noted that, when the target indication information includes multicast DCI, the period of the search space indication associated with the target indication information refers to the period configuration indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration corresponding to the multicast DCI. Specifically, the parameter indicates the period length and the starting time slot offset of the period. The target period is different from the period of the search space indication associated with the target indication information, which means that the period configuration corresponding to the target period exists independently of the period configuration of the search space indication corresponding to the multicast DCI. In other words, the period length of the target period is different from the period length indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI, and / or the period start offset of the target period is different from the period start offset indicated by the monitoringSlotPeriodicityAndOffset parameter in the search space configuration associated with the multicast DCI.

[0221] That is, when the target device determines that a target event occurs, the target discontinuous transmission of the first cell may be deactivated within a target period different from the period indicated by the search space associated with the target indication information for activating / deactivating the target discontinuous transmission of the first cell.

[0222] Further, the target period may be a positive integer multiple of the period of the target discontinuous transmission of the first cell.

[0223] The third behavior is: not transmitting the first preset signal / channel during the target time period, and / or transmitting the second preset signal / channel during the target time period.

[0224] Optionally, the target period is an inactive period in a current cycle of target discontinuous transmission of the first cell, and / or an inactive period in Y cycles after the current cycle, where Y is a positive integer equal to or greater than 1.

[0225] That is to say, for the third behavior mentioned above, when determining that the target event has occurred, the target device may transmit the first preset signal / channel in a target discontinuous transmission activation manner within the current period of the target discontinuous transmission of the first cell or Y periods after the current period, and / or transmit the second preset signal / channel in a target discontinuous transmission deactivation manner.

[0226] Optionally, the target time period is an inactive time period of the target discontinuous transmission included in a target period, and the target period is different from the period of the search space indication associated with the target indication information for activating / deactivating the target discontinuous transmission of the first cell.

[0227] That is to say, for the third behavior described above, when determining that the target event occurs, the target device may not transmit the first preset signal / channel during the inactive period of the target discontinuous transmission included in the target cycle, and / or transmit the second preset signal / channel during the inactive period of the target discontinuous transmission included in the target cycle. In other words, during the inactive period of the target discontinuous transmission included in the target cycle, the first preset signal / channel is transmitted in a manner of activating the target discontinuous transmission, and / or the second preset signal / channel is transmitted in a manner of deactivating the target discontinuous transmission.

[0228] Further, the target period may be a positive integer multiple of the period of the target discontinuous transmission of the first cell.

[0229] For the third behavior, in an optional implementation, the target discontinuous transmission is the DTX of the first cell, that is, the first cell of the terminal device is configured with DTX, and the target indication information is used to indicate activation / deactivation of the DTX of the first cell. In this case, the first preset signal / channel may include at least one of the following: a periodic CSI reference signal (P-CSI-RS) for channel state information (CSI) reporting, a semi-persistent CSI reference signal (SP-CSI-RS) for CSI reporting, a P-CSI-RS for radio link monitoring (RLM), an SP-CSI-RS for RLM, a P-CSI-RS for beam failure detection (BFD), an SP-CSI-RS for BFD, a P-CSI-RS for beam failure recovery (BFR), an SP-CSI-RS for BFR, a P-CSI-RS for radio resource management (RRM), an SP-CSI-RS for RRM, and a beam management (beam management, P-CSI-RS for BM), SP-CSI-RS for BM, P-CSI-RS for tracking, SP-CSI-RS for tracking, P-CSI-RS for positioning, SP-CSI-RS for positioning.

[0230] Among them, the P-CSI-RS used for CSI reporting can also be expressed as "P-CSI-RS for CSI reporting", and the SP-CSI-RS used for CSI reporting can also be expressed as "SP-CSI-RS for CSI reporting".

[0231] The P-CSI-RS for RLM may also be expressed as "P-CSI-RS for RLM", and the SP-CSI-RS for RLM may also be expressed as "SP-CSI-RS for RLM". Alternatively, the P / SP CSI-RS for RLM may also be expressed as "CSI-RS associated with RadioLinkMonitoringConfig or RadioLinkMonitoringRS".

[0232] The P-CSI-RS for BFD may also be expressed as "P-CSI-RS for BFD", and the SP-CSI-RS for BFD may also be expressed as "SP-CSI-RS for BFD". Alternatively, the P / SP CSI-RS for BFD may be expressed as "CSI-RS associated with BeamFailureRecoveryConfig or BeamFailureRecoveryRSConfig".

[0233] The P-CSI-RS for BFR can also be expressed as "P-CSI-RS for BFR", and the SP-CSI-RS for BFR can also be expressed as "SP-CSI-RS for BFD". Alternatively, the P / SP CSI-RS for BFR can be expressed as "CSI-RS associated with CandidateBeamRS".

[0234] The P-CSI-RS for RRM can also be expressed as "P-CSI-RS for RRM", and the SP-CSI-RS for RRM can also be expressed as "SP-CSI-RS for RRM". Alternatively, the P / SP CSI-RS for RRM can be expressed as "CSI-RS associated with MeasObjectNR, ReferenceSignalConfig or csi-rs-ResourceConfigMobility".

[0235] The P-CSI-RS for BM may also be expressed as "P-CSI-RS for BM", and the SP-CSI-RS for BM may also be expressed as "SP-CSI-RS for BM". Alternatively, the P / SP CSI-RS for BM may be expressed as "CSI-RS associated with CSI-reportconifg of the reporting configuration cri-RSRP / L1-RSRP / L1-SINR".

[0236] The P-CSI-RS used for tracking may also be expressed as "P-CSI-RS for tracking", and the SP-CSI-RS used for tracking may also be expressed as "SP-CSI-RS for tracking". Alternatively, the P / SP CSI-RS used for tracking may be expressed as "CSI-RS with TRS-info configured as true".

[0237] The P-CSI-RS used for positioning may also be expressed as “P-CSI-RS for positioning”, and the SP-CSI-RS used for positioning may also be expressed as “SP-CSI-RS for positioning”. Alternatively, the P / SP CSI-RS used for positioning may also be expressed as PRS (ie, positioning RS).

[0238] In another optional implementation, the target discontinuous transmission is DTX of the first cell, and the second preset signal / channel may include at least one of the following: a physical downlink control channel (PDCCH) scrambled by a cell radio network temporary identifier (C-RNTI), a PDCCH scrambled by a configured scheduling radio network temporary identifier (CS-RNTI), a modulation and coding scheme cell radio network temporary identifier (modulation and coding scheme cell radio network temporary identifier, identifier, MCS-C-RNTI), PDCCH scrambled by interruption wireless network temporary identifier INT-RNTI, PDCCH scrambled by slot format indication wireless network temporary identifier SFI-RNTI, PDCCH scrambled by uplink shared channel power control wireless network temporary identifier TPC-PUSCH-RNTI, PDCCH scrambled by uplink control channel power control wireless network temporary identifier TPC-PUCCH-RNTI, PDCCH scrambled by channel sounding reference signal power control wireless network temporary identifier TPC-SRS-RNTI, PDCCH scrambled by cancellation indication wireless network temporary identifier CI-RNTI, PDCCH scrambled by availability indication wireless network temporary identifier AI-RNTI, semi persistent scheduled physical downlink shared channel (semi persistent scheduled physical downlink shared channel, SPS PDSCH).

[0239] In the above implementation, when the target discontinuous transmission is DTX, it is specified how to transmit the preset first preset signal / channel, and / or, the second preset signal / channel when the target device determines that the target event occurs, and further defines which signals and / or channels the first preset signal / channel, and / or, the second preset signal / channel specifically include. The limitation on the first preset signal / channel can prevent the terminal device from receiving such signals / channels during inactive periods, thereby ensuring the accuracy of the measurement results of the terminal device and reducing the adverse effects on link performance. The limitation on the second preset signal / channel can enable the terminal device to receive such signals / channels during the inactive period of DTX, thereby reducing the adverse effects on the transmission performance of such signals / channels. This can effectively reduce the problem of impaired transmission performance of the communication system caused by the inability of the terminal device and the network device to consistently activate / deactivate the first DTX of the first cell, and can improve the transmission reliability of the communication system.

[0240] Optionally, the first cell is also configured with at least one second DTX. In this case, the target indication information can be used to instruct the terminal device to activate / deactivate the first DTX and at least one second DTX of the first cell. The period of the first DTX should be longer than or equal to the period of each second DTX in the at least one second DTX. Alternatively, the active period of the first DTX should be shorter than or equal to the active period of each second DTX. Alternatively, the period of the first DTX should be longer than or equal to the period of each second DTX in the at least one second DTX and the active period of the first DTX should be shorter than or equal to the active period of each second DTX.

[0241] That is to say, in the case where the first cell is configured with the first DTX and at least one second DTX, if the target device determines that the target event occurs, the DTX with the longest period and / or the shortest active period can be determined from the above-mentioned first row DTX and at least one second DTX (for the convenience of distinction, the target DTX will be used instead of the expression below), and the first preset signal / channel mentioned above is not transmitted during the inactive period of the current cycle of the target DTX or Y cycles after the current cycle, and / or the second preset signal / channel is transmitted during the inactive period of the current cycle of the target DTX or Y cycles after the current cycle. It can also be understood that, in the case where the first cell of the terminal device is configured with multiple DTXs, if the target device determines that the target event occurs, the first preset signal / channel mentioned above can be transmitted in a manner that the DTX with the longest period and / or the shortest active period is activated, and the second preset signal / channel mentioned above can be transmitted in a manner that the DTX with the longest period and / or the shortest active period is deactivated.

[0242] Alternatively, in a case where the first cell is configured with a first DTX and at least one second DTX, if the target device determines that a target event has occurred, it may determine a target DTX with the longest period and / or the shortest active period among the above-mentioned first DTX and at least one second DTX, and may not transmit the first preset signal / channel mentioned above during the inactive period of the target discontinuous transmission of the target DTX included in the target period, and / or may transmit the second preset signal / channel during the inactive period of the target discontinuous transmission of the target DTX included in the target period.

[0243] In the above implementation, when the first cell of the terminal device is configured with multiple DTXs, it is clarified that the terminal device transmits the first preset signal / channel mentioned above in accordance with which DTX is activated. This can effectively solve the problem of how to reduce the damage to the transmission performance of the communication system when the first cell is configured with multiple DTXs.

[0244] Optionally, when the target device determines that the target event occurs and determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DTX of the first cell or Y cycles after the current cycle in accordance with the first DTX activation mode, after it obtains the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel, if it is determined that the first transmission resource partially overlaps with the active period of the above-mentioned first DTX in the time domain, then the above-mentioned first preset signal / channel and / or, the above-mentioned second preset signal / channel may be transmitted on the first transmission resource. That is to say, even if the target device determines to deactivate the first preset signal / channel in accordance with the first DTX in the current cycle of the first DTX or Y cycles after the current cycle, when it determines that the first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active period of the above-mentioned first DTX in the time domain, then the above-mentioned first preset signal / channel and / or, the above-mentioned second preset signal / channel will still be transmitted on the first transmission resource.

[0245] Similarly, if Figure 5 As shown, when the target device determines that the target event occurs, it determines that the above-mentioned first preset signal / channel can be transmitted in the current cycle of the first DTX of the first cell in accordance with the first DTX activation mode, and the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel partially overlaps with the active time period in the current cycle of the first DTX in the time domain, that is, the time period corresponding to the first transmission resource partially overlaps with the active time period in the current cycle of the first DTX. At this time, the target device will still transmit the above-mentioned first preset signal / channel, and / or, the second preset signal / channel on the first transmission resource.

[0246] The above implementation method solves the problem of how to transmit the first preset signal / channel, and / or the second preset signal / channel when the first transmission resource corresponding to the first preset signal / channel and / or the second preset signal / channel conflicts with the active period of the first DTX understood as an activated state, and can reduce the leakage of the first preset signal / channel and / or the second preset signal / channel.

[0247] For the third behavior, in another optional implementation, the target discontinuous transmission is the DRX of the first cell, that is, the first cell of the terminal device is configured with DRX, and the target indication information is used to indicate activation / deactivation of the DRX of the first cell. In this case, the first preset signal / channel may include at least one of the following: a configured grant PUSCH (CG PUSCH), (scheduling request, SR).

[0248] Optionally, the above-mentioned SR may include a scheduling request SR with a physical layer priority index configured as 0, and / or an SR associated with a logical channel with a low priority at the MAC layer. Among them, the SR with a physical layer priority index configured as 0 can be expressed as "SR with the phy-PriorityIndex-r16 field configured as p0", "SR with the physical layer priority configured as 0" or "SR with a low priority at the physical layer". Here, a low-priority logical channel refers to a logical channel with a larger MAC layer parameter priority configuration value when multiple logical channels are associated with the SR configuration, or a logical channel with a priority configuration value less than or equal to s. s is a positive integer. For example, assuming there are three logical channels with corresponding MAC priorities of 1, 5, and 10, respectively, the logical channels with a priority of 10, or priorities of 5 and 10 are considered to be logical channels with a low priority at the MAC layer.

[0249] In another optional implementation, the target discontinuous transmission is the DRX of the first cell, and the second preset signal / channel may include at least one of the following: P-SRS for positioning function, SP-SRS for positioning function, P-SRS other than for positioning function, SP-SRS other than for positioning function, HARQ-ACK associated with SPS PDSCH, periodic channel state information (periodic CSI, P-CSI), semi-persistent channel state information (semi-persistent CSI, SP-CSI). Among them, the P-SRS for positioning function can also be expressed as "P-SRS for positioning", the SP-SRS for positioning function can also be expressed as "SP-SRS for positioning", and the HARQ-ACK associated with SPS PDSCH can also be expressed as "ACK for SPS PDSCH".

[0250] In the above implementation, when the first cell of the terminal device is configured with DRX, it is specified how to transmit the preset first preset signal / channel, and / or, the second preset signal / channel when the target device determines that the target event occurs, and further defines which channels and / or signals the first preset signal / channel, and / or, the second preset signal / channel specifically include. The limitation on the first preset signal / channel can prevent the terminal device from sending such signals / channels during the inactive period of DRX, ensuring that the network device can correctly receive such uplink transmissions, and reducing the adverse effects on link performance. The limitation on the second preset signal / channel can prevent the terminal device from sending such signals / channels during the inactive period of DRX, ensuring that the network device can receive such transmissions, and reducing the adverse effects on link performance. This can effectively reduce the damage to the transmission performance of the communication system caused by the inability of the terminal device and the network device to consistently activate / deactivate the first DRX of the first cell, and can improve the transmission reliability of the communication system.

[0251] Optionally, the first cell is also configured with at least one second DRX. In this case, the target indication information can be used to instruct the terminal device to activate / deactivate the first DRX and at least one second DRX of the first cell. The cycle of the first DRX should be longer than or equal to the cycle of each second DRX in the at least one second DRX. Alternatively, the active period of the first DRX should be shorter than or equal to the active period of each second DRX. Alternatively, the cycle of the first DRX should be longer than or equal to the cycle of each second DRX in the at least one second DRX and the active period of the first DRX should be shorter than or equal to the active period of each second DRX.

[0252] That is to say, in the case where the first cell is configured with the first DRX and at least one second DRX, if the target device determines that the target event occurs, the DRX with the longest cycle and / or the shortest active period can be determined from the above-mentioned first row DRX and at least one second DRX (for the convenience of distinction, the target DRX will be used instead of the expression below), and the first preset signal / channel mentioned above is not transmitted during the inactive period of the current cycle of the target DRX or Y cycles after the current cycle, and / or the second preset signal / channel is transmitted during the inactive period of the current cycle of the target DRX or Y cycles after the current cycle. It can also be understood that, in the case where the first cell of the terminal device is configured with multiple DRXs, if the target device determines that the target event occurs, the first preset signal / channel mentioned above can be transmitted in a manner that the DRX with the longest cycle and / or the shortest active period is activated, and the second preset signal / channel mentioned above can be transmitted in a manner that the DRX with the longest cycle and / or the shortest active period is deactivated.

[0253] Alternatively, in the case where the first cell is configured with a first DRX and at least one second DRX, if the target device determines that a target event has occurred, it may determine a target DRX with the longest cycle and / or the shortest active period among the first DRX and the at least one second DRX, and may not transmit the first preset signal / channel mentioned above during the inactive period of the target discontinuous transmission of the target DRX included in the target cycle, and / or may transmit the second preset signal / channel during the inactive period of the target discontinuous transmission of the target DRX included in the target cycle.

[0254] In the above implementation, when the first cell of the terminal device is configured with multiple DRXs, it is clarified that the target device transmits the first preset signal / channel mentioned above in accordance with which DRX is activated, and transmits the second preset signal / channel mentioned above in accordance with which DRX is deactivated. This can effectively solve the problem of how to reduce the damage to the transmission performance of the communication system when the first cell is configured with multiple DRXs.

[0255] Optionally, when the target device determines that the target event occurs and determines to transmit the above-mentioned first preset signal / channel in the current cycle of the first DRX of the first cell or Y cycles after the current cycle in accordance with the first DRX activation mode, after it obtains the above-mentioned first preset signal / channel, and / or, the first transmission resource corresponding to the second preset signal / channel, if it is determined that the second transmission resource partially overlaps with the active period of the above-mentioned first DRX in the time domain, then the above-mentioned first preset signal / channel, and / or, the above-mentioned second preset signal / channel may be transmitted on the second transmission resource. That is to say, even if the terminal device determines to deactivate the first preset signal / channel in accordance with the first DRX in the current cycle of the first DRX or Y cycles after the current cycle, when it determines that the above-mentioned first preset signal / channel, and / or, the second transmission resource corresponding to the second preset signal / channel partially overlaps with the active period of the above-mentioned first DRX in the time domain, then the above-mentioned first preset signal / channel, and / or, the above-mentioned second preset signal / channel will still be transmitted on the second transmission resource.

[0256] The above implementation method solves the problem of how to transmit the first preset signal / channel, and / or the second preset signal / channel when the second transmission resource corresponding to the first preset signal / channel and / or the second preset signal / channel conflicts with the active period of the first DRX understood as being in an activated state, thereby avoiding leakage of the first preset signal / channel, and / or the second preset signal / channel.

[0257] In some feasible implementations, when the target device is a terminal device, after it determines that the target event has occurred, it may not detect the target indication information for activating / deactivating the target discontinuous transmission of the first cell within the target discontinuous transmission period of the first cell. Since the target event will affect the transmission of the target indication information between the terminal device and the network device when it is determined that the target event has occurred, the method of not detecting the target indication information within the target discontinuous transmission period of the first cell can further save the power consumption of the terminal device.

[0258] In some feasible implementations, when the target device is a network device, after it determines that the target event has occurred, it may not send target indication information for activating / deactivating the target discontinuous transmission of the first cell within the target discontinuous transmission period of the first cell. Since the target event will affect the transmission of target indication information between the terminal device and the network device when it is determined that the target event has occurred, the method of not sending the target indication information within the target discontinuous transmission period of the first cell can further save the power consumption of the network device.

[0259] In some feasible implementations, when the target device performs the above-mentioned first behavior, the above-mentioned second behavior, or performs the above-mentioned third behavior and the target time period is an inactive time period of the target discontinuous transmission included in the target cycle, when the target device is a terminal device, it can receive the cycle configuration information corresponding to the target cycle sent by the network device. Among them, the cycle configuration information at least includes the cycle length and starting offset of the target cycle. Further, the terminal device can determine the above-mentioned target cycle based on the cycle length and starting offset of the target cycle. For example, assuming that the cycle length of the target cycle is 80ms and the starting offset is 20ms, the terminal device can determine that the starting time of the target cycle is 20ms, 100ms, 180ms, 260ms, etc.

[0260] Correspondingly, in this case, when the target device is a network device, it can also generate and send period configuration information corresponding to the above target period to the terminal device, so that the terminal device can determine the above target period based on the period configuration information.

[0261] In the communication method provided in this embodiment, the specific behaviors of the terminal device and the network device are specified when a target event occurs that will affect the transmission of target indication information between the terminal device and the network device. This can also reduce the damage to the transmission performance of the communication system caused by the discontinuous transmission of the activation / deactivation cell that the terminal device and the network device cannot consistently activate / deactivate.
