Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, apparatus, device and system. Background Art

[0002] With the development of wireless communication technology, most terminal devices currently support dual SIM dual active (DSDA) mode. In DSDA mode, the terminal device supports dual SIM services concurrently, that is, the dual SIM cards can send or receive data at the same time.

[0003] The DSDA mode includes the DSDA transmit sharing (TX Sharing) mode. In the DSDA transmit sharing mode, two cards of the terminal device usually need to compete for the use of the same RF transmission path through time division multiplexing (TDM) to send uplink data.

[0004] When a terminal device fails to transmit uplink data, the network device can issue a transmit power control (TPC) command to the terminal device, instructing it to increase the transmit power and resend uplink data. However, when the RF transmit path is preempted by a card with a high-priority service, the card with a low-priority service cannot send uplink data to the network device, resulting in unnecessary TPC overhead for the network device. Summary of the Invention

[0005] The embodiments of the present application provide a communication method, apparatus, device, and system to avoid incorrect adjustment of the transmission power of a terminal device by a network device, thereby reducing device overhead.

[0006] In the first aspect, an embodiment of the present application proposes a communication method, which is applied to a terminal device, the terminal device including a first card, the method including: sending first information to a first network device, the first information being used to indicate that the radio frequency transmission path of the terminal device is occupied on a first uplink resource; the first network device is a network device corresponding to the cell where the terminal device resides through the first card, and the first uplink resource is a resource configured by the first network device for the first card for sending first uplink data.

[0007] In the above scheme, the terminal device sends a first message to the first network device to inform the first network device that the terminal device's radio frequency transmission path is preempted by the second card on the first uplink resource, so that the first network device can suspend the transmission power control of the terminal device based on the first information, avoid the first network device from misadjusting the transmission power of the terminal device, and reduce unnecessary overhead of the terminal device and the first network device.

[0008] In an optional embodiment of the first aspect, the first information includes at least one of the following: a first identifier, the first identifier is used to indicate that a radio frequency transmission path of the terminal device is occupied; and indication information of the first uplink resource.

[0009] In an optional embodiment of the first aspect, the first uplink resource includes at least one of the following: a physical uplink control channel PUCCH resource; and a physical uplink shared channel PUSCH resource.

[0010] In an optional embodiment of the first aspect, the first information is carried in uplink control information UCI.

[0011] In an optional embodiment of the first aspect, the terminal device further includes a second card, and before sending the first information to the first network device, the method further includes:

[0012] Receive fourth information from the first network device, and receive fifth information from the second network device; the fourth information is used to instruct the first card to send first uplink data on the second uplink resource, and the fifth information is used to instruct the second card to send second uplink data on the third uplink resource; the second uplink resource and the third uplink resource both include the first uplink resource.

[0013] In the above scheme, the first network device configures the second uplink resource for sending the first uplink data for the first card of the terminal device by sending the fourth information; the second network device configures the third uplink resource for sending the second uplink data for the second card of the terminal device by sending the fifth information.

[0014] Among them, the second uplink resource may refer to the second uplink time domain resource, the third uplink resource may refer to the third uplink time domain resource, the first uplink resource may refer to the first uplink time domain resource, and there is an overlapping area between the second uplink time domain resource and the third uplink time domain resource, and the overlapping area is the first uplink time domain resource.

[0015] In an optional embodiment of the first aspect, sending the first information to the first network device includes:

[0016] If the priority of the first uplink data is lower than the priority of the second uplink data, the first information is sent to the first network device.

[0017] In the above scheme, the terminal device sends the first uplink data through the first card and sends the second uplink data through the second card. Since the first card and the second card of the terminal device share the same radio frequency transmission path, within a certain period of time, when the first card and the second card both have uplink data to send, the terminal device gives priority to sending the second uplink data with a higher priority, and sends the first information to the first network device to inform the first network device that the radio frequency transmission path of the terminal device has been preempted by the second card.

[0023] In an optional embodiment of the first aspect, the method further includes: sending sixth information to the first network device, where the sixth information is used to indicate that a radio frequency transmission path of the terminal device is not occupied.

[0025] In an optional embodiment of the first aspect, sending the sixth information to the first network device includes: when the radio frequency transmission path is occupied by the second card of the terminal device, after the second card completes sending the second uplink data, sending the sixth information to the first network device.

[0065] In order to better understand the technical solution provided by this application, the communication system architecture of this application is first described below.

Figure 1 As shown, the communication system includes one or more access network devices and one or more terminal devices connected to the access network devices. Figure 1 The example shows two access network devices (eg, base station 10 and base station 20) and one terminal device (eg, UE30). It can be understood that Figure 1 This is only an example and does not limit the applicable scenarios of the technical solutions provided in this application.

[0067] The access network device can be a transmission reception point (TRP), a base station, a relay station, a node or an access point, etc. The access network device can be an access network device in a 5G communication system or an access network device in a future evolution network.

Satellite communication systems can be integrated with traditional mobile communication systems.

[0073] In the embodiment of this application, Figure 1 The illustrated UE 30 may be provided with two subscriber identity modules (SIMs), namely SIM card 1 and SIM card 2. SIM card 1 and SIM card 2 may be connected to the same operator network or to different operator networks, and this application does not impose any restrictions thereon. SIM card 1 and SIM card 2 may be connected to the same access network device or to different access network devices, and this application does not impose any restrictions thereon.

[0074] The following example illustrates the solution using SIM card 1 and SIM card 2 connected to different access network devices. For example, Figure 1 The UE 30 shown communicates with the base station 10 via the SIM card 1 , and the UE 30 communicates with the base station 20 via the SIM card 2 .

[0075] In some embodiments, UE 30 may transmit uplink data based on the uplink scheduling of base station 10. For example, UE 30 sends uplink data to base station 10 via SIM card 1 on the uplink resources configured by base station 10 for SIM card 1.

[0076] In some embodiments, UE 30 may transmit uplink data based on the uplink scheduling of base station 20. For example, UE 30 transmits uplink data to base station 20 via SIM card 2 on the uplink resources configured by base station 20 for SIM card 2.

[0077] The following combination Figure 2 The uplink scheduling process provided in the embodiment of the present application is described in detail.

[0078] refer to Figure 2 , Figure 2 The following is a schematic diagram of an uplink scheduling process provided by an embodiment of the present application. Figure 2 As shown, the uplink scheduling process involves interaction between UE 30 and base station 10, and may include:

[0079] S201. UE 30 sends an uplink scheduling request (SR) to the base station 10. The uplink scheduling request is used to request resources for uplink data transmission.

[0080] After a radio resource control (RRC) connection is established between UE 30 and base station 10 , when UE 30 has uplink data to send, UE 30 may send an SR to base station 10 .

[0081] In some embodiments, the UE 30 may send an SR to the base station 10 via the SIM card 1 .

[0082] In some embodiments, the UE 30 may send an SR to the base station 10 via a physical uplink control channel (PUCCH).

[0083] S202 . The base station 10 sends uplink grant (UL grant) information to the UE 30 . The UL grant information is used to indicate the uplink resources configured by the base station 10 for the UE 30 .

[0084] After receiving the SR, base station 10 may configure uplink resources for UE 30 and send UL grant information to UE 30. The UL grant information includes the uplink resources configured by base station 10 for UE 30. Uplink resources include uplink time-frequency domain resources. In the embodiment of the present application, uplink resources mainly refer to uplink time domain resources.

[0085] In some embodiments, the SR includes information about SIM card 1 of UE 30, for example, the information about SIM card 1 includes an international mobile subscriber identity (IMSI). After receiving the SR, base station 10 may configure uplink resources for SIM card 1 of UE 30 and send UL grant information to UE 30. The UL grant information includes the uplink resources configured by base station 10 for SIM card 1 of UE 30, which are recorded as uplink resources 1.

[0086] S203. UE30 sends uplink data and / or buffer status report (BSR).

[0087] After receiving the UL grant information, UE30, in one example, sends uplink data or a BSR on uplink resource 1 through SIM card 1, where the BSR is used to indicate the amount of uplink data to be sent in the medium access control (MAC) layer buffer of UE30. In another example, UE30 sends uplink data and a BSR on uplink resource 1 through SIM card 1.

[0088] S204 . The base station 10 sends an ACK / NACK message to the UE 30 .

[0089] In some embodiments, after the base station 10 successfully receives the uplink data sent by the UE 30 , the base station 10 may send an acknowledgement (ACK) message to the UE 30 .

[0090] In some embodiments, if the base station 10 does not receive uplink data sent by the UE 30 within a preset period of time, or if the base station 10 fails to receive uplink data sent by the UE (data loss or decoding failure, etc.), the base station 10 may send a negative acknowledgement (NACK) message to the UE 30 .

[0091] In some embodiments, after S203, the following steps may be further performed:

[0092] S205 . The base station 10 sends UL grant information to the UE 30 again. The UL grant information is used to indicate the uplink resources configured by the base station 10 for the UE 30 .

[0093] After receiving the BSR, base station 10 learns that the amount of uplink data sent by UE 30 is greater than the preset data amount. Base station 20 may reconfigure uplink resources for UE 30, designated as uplink resource 3, and resend UL grant information to UE 30. The UL grant information includes indication information for uplink resource 3. Exemplarily, the indication information for uplink resource 3 is used to indicate the start time and duration of uplink resource 3, or to indicate the start time and end time of uplink resource 3. UE 30 may send uplink data on uplink resource 3.

[0094] It should be understood that the uplink scheduling process between UE30 and base station 20 is similar to the uplink scheduling process between UE30 and base station 10, which can be referred to Figure 2 The embodiment shown.

[0095] Based on the above uplink scheduling process, base station 10 can configure uplink resource 1 for SIM card 1 of UE 30. Similarly, base station 20 can configure uplink resource 2 for SIM card 2 of UE 30.

[0096] In order to better understand the solution, the time domain resource structure of the uplink resources provided in the embodiment of the present application is introduced below.

[0097] In the embodiment of the present application, time domain resources may refer to frames, subframes, time slots, and symbols used for uplink and downlink (UL & DL) transmissions, wherein a symbol may refer to an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0098] refer to Figure 3 , Figure 3 The schematic diagram of the structure of time domain resources is exemplarily shown.

[0099] like Figure 3 As shown, the duration of a frame is generally 10 milliseconds (ms), and a frame may generally include 10 subframes, which may be marked as subframe 0 to subframe 9 respectively.

[0100] A subframe can include one or more time slots, and the number of time slots is related to the subcarrier spacing. For example, when the subcarrier spacing is 15 kilohertz (KHz), a subframe can include one time slot, which can be marked as Slot0; when the subcarrier spacing is 30 KHz, a subframe can include two time slots, marked as Slot0 and Slot1; when the subcarrier spacing is 60 KHz, a subframe can include four time slots, marked as Slot0, Slot1, Slot2, and Slot3. In the following embodiments, the subcarrier spacing is 30 KHz, and a subframe includes two time slots.

[0101] A timeslot typically contains 14 symbols, which can be denoted as s0 to s13. A symbol is the smallest unit of the time domain resource structure. A symbol can be an uplink symbol used for uplink transmission, which can be marked as "U," or a downlink symbol used for downlink transmission, which can be marked as "D." Based on the ratio of uplink symbols to downlink symbols in a timeslot, timeslots can be divided into three types: uplink timeslots, downlink timeslots, and flexible timeslots.

[0102] Reference Figure 4 , Figure 4 Schematic diagrams of different types of time slots are shown as examples. Figure 4As shown, an uplink timeslot can be marked as "U," and all 14 symbols in the uplink timeslot are uplink symbols; a downlink timeslot can be marked as "D," and all 14 symbols in the downlink timeslot are downlink symbols; and a flexible timeslot can be marked as "S," which is divided into fully flexible timeslots and hybrid timeslots. The 14 symbols in a fully flexible timeslot can all be used for uplink transmission, downlink transmission, as a guard interval, or as reserved resources, based on specific service scenarios. A hybrid timeslot includes at least one uplink symbol and / or downlink symbol. Figure 4 In the mixed time slot shown, s0 to s7 are downlink symbols, s8 and s9 are guard intervals, and s10 to s13 are uplink symbols.

[0103] Reference Figure 5 , Figure 5 The structural diagram of time domain resources with different time slot ratios is shown as an example. Figure 5 As shown, within a period (e.g., 2.5ms, 5ms, etc.), based on the ratio between uplink time slots, downlink time slots and flexible time slots, different time slot ratios can be used in the time domain. Figure 5 As shown in (a), with 2.5ms as a period, the time slot ratio can be expressed as D:S:U=3:1:1. Figure 5 As shown in (b), with 5ms as a period, the time slot ratio can be expressed as D:S:U=5:2:3. Figure 5 As shown in (c), with 5ms as a period, the time slot ratio can be expressed as D:S:U=8:1:1. Figure 5 As shown in (d), with 5 ms as a period, the time slot ratio can be expressed as D:S:U=7:1:2.

[0104] The time domain resource structure introduced above is only used to exemplify the present application and does not constitute a specific limitation to the present application.

[0105] Based on the foregoing, a process for sending uplink data provided by an embodiment of the present application is described below.

[0106] Continue to refer to Figure 1 , Figure 1 The UE 30 shown can communicate using a dual SIM and dual active (DSDA) mode. In this communication mode, two SIM cards can perform communication services simultaneously. That is, while one of the two SIM cards performs a high-priority service with high real-time requirements (e.g., voice call service), the other SIM card can perform a low-priority service with low real-time requirements (e.g., web browsing service).

[0107] For example, during a certain period of time, when SIM card 1 of UE 30 is executing a high-priority service with a high real-time requirement, SIM card 2 can execute a low-priority service with a low real-time requirement. During another period of time, when SIM card 2 of UE 30 is executing a high-priority service with a high real-time requirement, SIM card 1 can execute a low-priority service with a low real-time requirement. In other words, the SIM card that executes the high-priority service and the SIM card that executes the low-priority service can vary, and this application does not limit this.

[0108] When UE 30 is configured with only one RF transmit path, the two SIM cards can use time division multiplexing to send uplink data to the base station using the same RF transmit path at different times. This mode of sharing a set of RF transmit paths through time division multiplexing is also called RF sharing mode. In some embodiments, the RF transmit path can also be described as an RF transmit channel or an uplink channel.

[0109] There is a possible scenario: base station 10 configures uplink resource 1 for SIM card 1, which is used by SIM card 1 to send uplink data 1. Base station 20 configures uplink resource 2 for SIM card 2, which is used by SIM card 2 to send uplink data 2. Uplink resource 1 and uplink resource 2 overlap in the time domain, and the priority of uplink data 1 is lower than that of uplink data 2. In this case, because the two SIM cards share a radio frequency transmission path, the radio frequency transmission path will be preempted by SIM card 2, which is performing a higher-priority service. SIM card 2 will typically occupy the radio frequency transmission path for the entire time domain of uplink resource 2, resulting in SIM card 1, which is performing a lower-priority service, being unable to use the radio frequency transmission path to send uplink data 1.

[0110] Reference Figure 6 , Figure 6 The following is an exemplary diagram showing the time domain resources configured by the base station for SIM card 1 and SIM card 2 respectively. Figure 6 As shown, in the same time period (10ms), the time slot ratio of the time domain resources configured by base station 10 for SIM card 1 is D:S:U=8:1:1, and the time slot ratio of the time domain resources configured by base station 20 for SIM card 2 is D:S:U=5:2:3.

[0111] In some embodiments, when the base station 20 schedules the SIM card 2 to Figure 6When a time slot (e.g., time slot 9) within the 10ms shown transmits uplink data 2 for a high-priority service, SIM card 2 preempts UE 30's RF transmit path for the entire 10ms, preventing SIM card 1 from using the RF transmit path to transmit uplink data 1 for a low-priority service. Because SIM card 2 preempts the RF transmit path, SIM card 1 is unable to transmit uplink data 1 in the uplink time slot (e.g., time slot 9 or time slot 19) configured for it by base station 10. Base station 10 may deem UE 30's uplink transmission to have failed.

[0112] In some embodiments, when UE30 is far away from the base station 10 or there are many obstacles between UE30 and the base station 10, the signal loss between UE30 and the base station 10 is large, which may cause the base station 10 to be unable to receive the uplink data 1 sent by UE30 through the SIM card 1 within a preset time period. The base station 10 may consider that the UE30 uplink transmission has failed.

[0113] Based on the two aforementioned embodiments, when base station 10 determines that UE 30 has failed uplink transmission, base station 10 can send a Transmit Power Control (TPC) command to UE 30. The TPC command instructs UE 30 to increase its transmit power. UE 30 can adjust its transmit power based on the TPC command. This process is called closed-loop power control.

[0114] However, with respect to the first embodiment described above, the base station 10 actually does not need to instruct the UE 30 to increase the transmit power. The reason is that even if the UE 30 increases the transmit power based on the TPC instruction sent by the base station 10, the base station 10 still cannot receive the uplink data 1 sent by the UE 30 through the SIM card 1 because the RF transmit path is preempted by the SIM card 2. That is to say, during the period when the RF transmit path is preempted by the SIM card 2, the SIM card 1 cannot use the RF transmit path to send the uplink data 1.

[0115] In view of the above analysis, it is unnecessary for the base station to send TPC instructions, which will result in higher signaling overhead for the device. It is also unnecessary for UE30 to increase the transmission power based on the TPC instructions, which will result in higher power overhead for the device.

[0116] In view of the above problems, the embodiment of the present application proposes a communication method, which can be applied to a terminal device having a first card and a second card (for example, Figure 1 UE30 shown), the terminal device operates in DSDA transmission sharing mode, when the terminal device needs to pass the first card (for example, Figure 1 The SIM card 1 shown in the figure) sends a signal to the first network device (eg, Figure 1 When the base station 10 shown in FIG. 10A sends uplink data, the terminal device recognizes that the radio frequency transmission path is blocked by the second card (for example, Figure 1As shown in FIG2 , if the SIM card 2) is preempted, the terminal device can send a first message to the first network device to inform the first network device that the RF transmission path of the terminal device is preempted by the second card on the first uplink resource, so that the first network device can suspend the transmission power control and uplink scheduling of the terminal device based on the first information, thereby avoiding the first network device from misadjusting the transmission power of the terminal device, and reducing unnecessary overhead of the terminal device and the first network device.

[0117] In the embodiment of the present application, the RF transmission path of the terminal device may be occupied by not only the first card or the second card, but also other modules or components of the terminal device, such as a satellite communication module, etc., which is not limited in the present application.

[0118] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.

[0119] Reference Figure 7 , Figure 7 The flowchart of a communication method provided by an embodiment of the present application is exemplarily shown. Figure 7 As shown, the communication method of this embodiment includes:

[0120] S701. The terminal device sends first information to the first network device, where the first information is used to indicate that the radio frequency transmission path of the terminal device is occupied on the first uplink resource.

[0121] In this embodiment, the terminal device includes a first card and a second card. The first card and the second card can compete for the use of the same radio frequency transmission path of the terminal device via a TDM method to transmit uplink data. The first network device is the network device corresponding to the cell where the terminal device resides via the first card. The first uplink resource is the resource configured by the first network device for the first card of the terminal device for transmitting the first uplink data.

[0122] For example, the terminal device is Figure 1 UE30 in the terminal device, the first card is SIM card 1 of UE30, the second card of the terminal device is SIM card 2 of UE30, and the first network device is Figure 1 Base station 10 in.

[0123] In some embodiments, the first information includes at least one of the following: a first identifier; and indication information of the first uplink resource.

[0124] The first identifier is used to indicate that the radio frequency transmission path of the terminal device is occupied, for example, the first identifier is 1. The indication information of the first uplink resource may include indication information of the start time and indication information of the duration of the first uplink resource, or indication information of the start time and indication information of the end time of the first uplink resource.

[0125] In some embodiments, the first uplink resource includes at least one of the following:

[0126] Physical uplink control channel (PUCCH) resources; physical uplink shared channel (PUSCH) resources.

[0127] In some embodiments, the first information is carried in uplink control information (UCI). In this embodiment, the terminal device sends UCI to the first network device, where the UCI includes the first information, and the first information is used to indicate that the RF transmission path of the terminal device is occupied on the first uplink resource.

[0128] In some embodiments, the terminal device operates in a DSDA transmission sharing mode. When the terminal device identifies a radio frequency conflict, the terminal device sends a first message to the first network device. Specifically, in the DSDA transmission sharing mode, the first card and the second card of the terminal device can use the same radio frequency transmission path of the terminal device through time division multiplexing. The terminal device can identify whether a radio frequency conflict has occurred based on the occupancy of the radio frequency transmission path.

[0129] For example, the terminal device recognizes that the RF transmission path is occupied by the second card of the terminal device, and can determine that a RF conflict has occurred. The terminal device can send a first message to the first network device during the gap (gap) when the second card uses the RF transmission path to inform the first network device that a RF conflict has occurred in the terminal device.

[0130] S702. The first network device suspends closed-loop power control of the radio frequency transmission path of the terminal device based on the first information.

[0131] The first network device suspends closed-loop power control of the radio frequency transmission path of the terminal device, which means that the first network device does not send a transmission power control TPC instruction to the terminal device.

[0132] Usually, refer to Figure 2 , the first network device (such as Figure 2 The base station 10) receives the terminal device (such as Figure 2After receiving the SR request of UE30), the first network device sends UL grant information to the terminal device. If the first network device does not receive the uplink signal (PUCCH signal or PUSCH signal, used to carry uplink data and / or BSR) sent by the terminal device within the preset time period, or the signal quality of the uplink signal received by the first network device is less than the threshold, the first network device can send a TPC instruction to the terminal device to instruct the terminal device to increase the transmission power.

[0133] The above process is the closed-loop power control process of the terminal device by the first network device. It should be understood that if the RF transmission path of the terminal device is occupied and the first card of the first network device cannot send the first uplink data, the first network device does not actually need to instruct the terminal device to increase the transmission power through the TPC command.

[0134] In view of this, the terminal device can send a first message to the first network device so that the first network device knows that the terminal device's RF transmission path is occupied. The first network device can suspend the closed-loop power control of the terminal device's RF transmission path based on the first information. In this way, the signaling overhead of the first network device can be saved.

[0135] In this embodiment, the RF transmission path of the terminal device being occupied may mean that the RF transmission path of the terminal device is occupied by the second card of the terminal device, or occupied by other communication modules of the terminal device (for example, a satellite communication module).

[0136] In some embodiments, the first network device suspends closed-loop power control of the RF transmission path of the terminal device within a preset period based on the first information. The preset period may be indicated by the terminal device or agreed upon by a protocol.

[0137] Exemplarily, after the terminal device determines the time period when the RF transmission path is occupied, the terminal device can indicate the time period through the first information, and the first network device can suspend the closed-loop power control of the RF transmission path of the terminal device during the time period indicated by the first information.

[0138] After the terminal device identifies the radio frequency conflict, it can send a first information to the first network device. The first information indicates that the radio frequency transmission path of the terminal device is occupied on the first uplink resource, that is, it indicates that the first card of the terminal device cannot use the radio frequency transmission path of the terminal device on the first uplink resource. After receiving the first information, the first network device can know that the reason why the terminal device did not send uplink data is the radio frequency conflict. In this way, the first network device can suspend the closed-loop power control of the radio frequency transmission path of the terminal device, that is, the first network device can not send the above-mentioned TPC instruction, which can avoid unnecessary signaling overhead of the first network device, and can also avoid higher power consumption overhead of the terminal device due to unnecessary increase in transmission power.

[0139] In some embodiments, after S701 , the following operations may be performed:

[0140] S703. The first network device suspends uplink scheduling of the first card of the terminal device based on the first information.

[0141] Suspending uplink scheduling of the first card of the terminal device means that the first network device does not send UL grant information to the terminal device.

[0142] Usually, refer to Figure 2 , the first network device (such as Figure 2 The base station 10) receives the terminal device (such as Figure 2 After receiving the SR request of UE30), the first network device sends UL grant information to the terminal device. If the first network device does not receive the uplink signal (PUCCH signal or PUSCH signal, used to carry uplink data and / or BSR) sent by the terminal device within the preset time period, or the signal quality of the uplink signal received by the first network device is less than the threshold, the first network device can send UL grant information to the terminal device again to realize uplink scheduling of the first card (SIM card 1) of the terminal device.

[0143] It should be understood that if the radio frequency transmission path of the terminal device is occupied and the first card of the first network device cannot send the first uplink data, the first network device actually does not need to send the UL grant information to the terminal device again.

[0144] In view of this, the terminal device can send the first information to the first network device so that the first network device knows that the terminal device's RF transmission path is occupied. The first network device can suspend the uplink scheduling of the first card of the terminal device based on the first information.

[0145] In some embodiments, the first network device suspends uplink scheduling of the first card of the terminal device within a preset period based on the first information. The preset period may be indicated by the terminal device or agreed upon by a protocol.

[0146] Exemplarily, after the terminal device determines the time period when the radio frequency transmission path is occupied, the terminal device may indicate the time period through the first information, and the first network device may suspend uplink scheduling of the first card of the terminal device during the time period indicated by the first information.

[0147] After the terminal device identifies the radio frequency conflict, it can send a first information to the first network device. The first information indicates that the radio frequency transmission path of the terminal device is occupied on the first uplink resource, that is, it indicates that the first card of the terminal device cannot use the radio frequency transmission path of the terminal device on the first uplink resource. After receiving the first information, the first network device can know that the reason why the terminal device did not send uplink data is the radio frequency conflict. In this way, the first network device can suspend the uplink scheduling of the terminal device, that is, the first network device can not send uplink scheduling information, thereby avoiding unnecessary signaling overhead of the first network device.

[0148] In some embodiments, after S701 , S702 and S703 may be executed.

[0149] Reference Figure 8 , Figure 8 The following is a schematic diagram showing another uplink scheduling process provided by an embodiment of the present application. Figure 7 Based on the embodiment shown, before executing S701, as shown in FIG. Figure 8 As shown, the uplink scheduling process of this embodiment includes:

[0150] S801a. The terminal device sends second information to the first network device, where the second information is used to request that first uplink data be sent through the first card of the terminal device.

[0151] In some embodiments, the second information is carried in an uplink scheduling request SR. For example, the second information may include information about a first card of the terminal device, for example, the first card is SIM card 1, and the information about the first card includes the IMSI of SIM card 1.

[0152] S801b. The terminal device sends third information to the second network device, where the third information is used to request that the second uplink data be sent through the second card of the terminal device.

[0153] In some embodiments, the third information is carried in an uplink scheduling request (SR). Exemplarily, the third information may include information about a second card of the terminal device, such as SIM card 2, and the second card information includes the IMSI of SIM card 2. After receiving the third information, the second network device configures uplink resources for the second card of the terminal device, which are recorded as third uplink resources. In one example, the third uplink resources include the first uplink resources.

[0154] The execution order of the above S801a and S801b is not limited. In some embodiments, S801b may be executed first and then S801a. It should be noted that when the terminal device operates in DSDA transmission sharing mode, S801a and S801b cannot be executed at the same time.

[0155] After S801a, you can execute:

[0156] S802a. The first network device sends fourth information to the terminal device, where the fourth information is used to instruct the first card of the terminal device to send the first uplink resource on the second uplink resource.

[0157] After receiving the second information, the first network device configures a second uplink resource for the first card of the terminal device and sends fourth information to the terminal device, where the fourth information may include indication information of the second uplink resource. The indication information of the second uplink resource may include indication information of a start time and an indication information of a duration of the second uplink resource, or indication information of a start time and an indication information of an end time of the second uplink resource.

[0158] In some embodiments, the fourth information is carried in downlink control information (DCI), that is, the first network device sends DCI to the terminal device, and the DCI includes the fourth information.

[0159] In the embodiment of the present application, the second uplink resource includes the first uplink resource.

[0160] After S801b, you can execute:

[0161] S802b. The second network device sends fifth information to the terminal device, where the fifth information is used to instruct the second card of the terminal device to send the second uplink resource on the third uplink resource.

[0162] After receiving the third information, the second network device configures a third uplink resource for the second card of the terminal device and sends fifth information to the terminal device, where the fifth information may include indication information of the third uplink resource. The indication information of the third uplink resource may include indication information of a start time and an indication information of a duration of the third uplink resource, or indication information of a start time and an indication information of an end time of the third uplink resource.

[0163] In some embodiments, the fifth information is carried in DCI, that is, the second network device sends DCI to the terminal device, and the DCI includes the fifth information.

[0164] In the embodiment of the present application, the third uplink resource includes the first uplink resource.

[0165] In the uplink scheduling process shown in this embodiment, after the terminal device receives the fourth information and the fifth information respectively, it can learn the second uplink resource configured by the first network device for the first card and the third uplink resource configured by the second network device for the second card. Since the second uplink resource and the third uplink resource both include the first uplink resource, that is, the uplink resources of the first card and the second card overlap (for example, Figure 6As shown in time slot 9 and time slot 19 within 10ms, the overlapping uplink resources are the first uplink resources, and the terminal device can be informed that there is a radio frequency conflict in the first uplink resource.

[0166] In some embodiments, based on Figure 8 In the illustrated embodiment, if the priority of the first uplink data is lower than the priority of the second uplink data, S701 may be executed. In this embodiment, the first card may be referred to as a low-priority card, and the second card may be referred to as a high-priority card. When the RF transmission path is occupied by the high-priority second card, the terminal device may send a first message to the first network device corresponding to the low-priority first card to inform the first network device that a RF conflict has occurred with the terminal device. Based on the first message, the first network device may suspend closed-loop power control of the RF transmission path of the terminal device and / or suspend uplink scheduling of the first card of the terminal device.

[0167] In other embodiments, based on the embodiment shown in 8, if the priority of the first uplink data is higher than the priority of the second uplink data, the terminal device can send seventh information to the second network device, and the seventh information is used to indicate that the RF transmission path of the terminal device is occupied on the first uplink resource.

[0168] In this embodiment, the seventh information is similar to the first information in the aforementioned embodiment, and related content may refer to the first information.

[0169] In this embodiment, the first card may be called a high-priority card and the second card may be called a low-priority card. When the RF transmission path is occupied by the high-priority first card, the terminal device may send the seventh information to the second network device corresponding to the low-priority second card to inform the second network device that a RF conflict has occurred in the terminal device. Based on the seventh information, the second network device may suspend the closed-loop power control of the RF transmission path of the terminal device and / or suspend the uplink scheduling of the second card of the terminal device.

[0170] Reference Figure 9 , Figure 9 The flowchart of another communication method provided by the embodiment of the present application is exemplarily shown. Figure 7 Based on the embodiment shown, Figure 9 As shown, the communication method of this embodiment includes:

[0171] S901. The terminal device sends sixth information to the first network device, where the sixth information is used to indicate that the radio frequency transmission path of the terminal device is not occupied.

[0172] In some embodiments, the sixth information includes a second identifier, and the second identifier is used to indicate that the radio frequency transmission path of the terminal device is not occupied, for example, the second identifier is 0.

[0173] In some embodiments, the sixth information is carried in UCI, that is, the terminal device sends UCI to the first network device, and the UCI includes the sixth information.

[0174] S902. The first network device resumes closed-loop power control of the radio frequency transmission path of the terminal device based on the sixth information.

[0175] The first network device resumes closed-loop power control of the radio frequency transmission path of the terminal device, which means that the first network device can send a TPC instruction to the terminal device under the conditions described in the above embodiment.

[0176] After the first network device suspends the closed-loop power control of the RF transmission path of the terminal device based on the first information sent by the terminal device, if the first network device receives sixth information indicating that the RF transmission path is not occupied by the terminal device, the first network device can resume the closed-loop power control of the RF transmission path of the terminal device.

[0177] In some embodiments, after S901, the following operations may be performed:

[0178] S903. The first network device resumes uplink scheduling for the first card of the terminal device based on the sixth information.

[0179] The first network device resumes uplink scheduling for the first card of the terminal device, which means that the first network device can send UL grant information to the terminal device again under the conditions described in the above embodiment.
