Those skilled in the art can know that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0031] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100 shown is an example, and the embodiments of the present disclosure are not limited thereto. Figure 1 The communication system can include Figure 1 all or part of the subjects in the above-mentioned communication system, or can include Figure 1 other subjects in addition to the above-mentioned subjects. The number and form of each subject is arbitrary, and the connection relationship between the subjects is an example. The subjects can be connected or not connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0032] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based on them, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0033] In the related art, the timing advance (TA) of a non-terrestrial network can be greater than one time unit (for example, a time slot), so that the uplink time slot timing of the terminal side needs to be advanced by at least one time unit relative to the downlink time slot timing. In the CONNECTED discontinuous reception (CDRX) configuration scenario, when data (for example, a sounding reference signal (SRS) or periodic channel state information (PCSI)) needs to be transmitted at time n, the terminal needs to determine whether to transmit data according to the CDRX state at time n estimated at time n-4 ms, and the network device needs to determine whether to receive data according to the CDRX state at time n estimated at time n-4 ms. In this way, if there is a TA command word (used to determine TA) between time n-4 ms and time n, and the timing deviation (that is, TA) between the uplink frame and the downlink frame spans one time unit, the terminal can not obtain the CDRX state in time, so that the CDRX states determined by the network side and the terminal are different, resulting in incorrect data transmission and affecting communication performance.

[0034] To solve the above technical problems, embodiments of the present disclosure provide a transmission control method, which determines an initial CONNECTED discontinuous reception (CDRX) state related to a second time based on a first time, wherein the first time is earlier than the second time, and determines whether a target timing advance (TA) corresponding to the second time is greater than a time unit to obtain a reference result, wherein the target TA is determined based on a TA adjustment amount, the determination time of the TA adjustment amount is later than the first time and earlier than the second time, and controls data transmission at the second time according to the initial CDRX state and the reference result. Thus, if the TA adjustment amount is determined between the first time and the second time, and the target TA is re-determined based on the TA adjustment amount, the data transmission control can be performed in combination with the reference result of whether the target timing advance (TA) is greater than a time unit, and the initial CDRX state estimated at the first time, which can improve the accuracy of data transmission and ensure communication performance.

[0035] In embodiments of the present disclosure, the "data" may, for example, be a sounding reference signal (SRS) and / or periodic channel state information (PCSI), without limitation.

[0036] In embodiments of the present disclosure, "transmission" can include sending and / or receiving, without limitation.

[0037] In embodiments of the present disclosure, the data transmission may, for example, be transmitting data and / or receiving data. Alternatively, in some embodiments, if the data transmission is performed by the terminal, the data transmission may be transmitting data for the terminal, and if the data transmission is performed by the network device, the data transmission may be receiving data for the network device, without limitation.

[0038] The transmission control method in embodiments of the present disclosure may be applied in a communication device, for example, the terminal, the network device, or the chip as described above, without limitation.

[0039] Figure 2 A flowchart of a transmission control method provided in embodiments of the present disclosure.

[0040] As shown in Figure 2 The transmission control method comprises the following steps.

[0041] Step S201: determining an initial connected mode discontinuous reception (CDRX) state related to a second time based on a first time, wherein the first time is earlier than the second time.

[0042] The first time refers to the time of performing the CDRX state estimation. When performing the CDRX state estimation, the CDRX state at the second time may be estimated. Alternatively, in some embodiments, the first time is earlier than the second time, and the first time and the second time may be separated by a certain time length. The time length may be, for example, 4 milliseconds (ms), without limitation. Alternatively, in some embodiments, the second time may be represented as n, and the first time may be represented as n-4ms, without limitation.

[0043] In the following examples, the time length between the first time and the second time may be 4ms for example, and of course, other arbitrary possible time lengths may also be applicable, without limitation.

[0044] Alternatively, in some embodiments, the CDRX state related to the time "n" may be estimated at the time "n-4ms". The estimated CDRX state may be referred to as the initial CDRX state. The initial CDRX state is used to control the data transmission (such as transmitting and / or receiving) at the time "n", without limitation.

[0045] In embodiments of the present disclosure, the time length between the first time and the second time may be determined according to the subcarrier spacing of the transmission frame. For example, when the subcarrier spacing is 15kmz, the time length between the first time and the second time is 4ms.

[0046] In embodiments of the present disclosure, the first time based on the first time may be understood as at the first time.

[0047] Optionally, in some embodiments, the initial CDRX state can be configured by the network device for the terminal, and the network device can determine the initial CDRX state related to the second time moment configured for the terminal at the first time moment, without limitation.

[0048] Optionally, in some embodiments, the terminal can receive the initial CDRX state configured by the network device for the second time moment at the first time moment, without limitation.

[0049] Optionally, in some embodiments, the initial CDRX state related to the second time moment can also be agreed by a protocol, and the network device or the terminal can determine the initial CDRX state related to the second time moment based on the protocol agreement, without limitation.

[0050] Step S202: determining whether a target timing advance TA corresponding to the second time moment is greater than a time unit to obtain a reference result, wherein the target TA is determined based on a TA adjustment amount, and a determination time of the TA adjustment amount is later than the first time moment and earlier than the second time moment.

[0051] In embodiments of the present disclosure, the reference result can include that the target TA is greater than the time unit, or the target TA is less than or equal to the time unit.

[0052] In some communication scenarios, the TA can be adjusted between the first time moment and the second time moment, and the adjusted TA can be referred to as a target TA. The target TA can be greater than (i.e., cross) a time unit. In addition, if the target TA is redetermined, the terminal and the network device can not update the initial CDRX state based on the target TA (for example, the terminal does not update the initial CDRX state, and the network device updates the initial CDRX state based on the target TA to obtain an updated CDRX state, at this time, the terminal transmits data using the initial CDRX state, and the network device receives data using the updated CDRX state), so the terminal and the network device can not be able to use consistent CDRX states for data transmission control. Therefore, in embodiments of the present disclosure, after the target TA is redetermined, the terminal and the network device can use consistent CDRX states for data transmission control based on the reference result of whether the target TA corresponding to the second time moment is greater than the time unit, so as to optimize the data transmission effect.

[0053] Optionally, in some embodiments, the time unit comprises: a time slot. That is, the time unit can be one time slot. Thus, the optimization control mechanism of data transmission can be effectively applied to the large TA scenario, and the cumulative TA in the NTN network is usually greater than one time slot, so as to further enable the optimization control mechanism of data transmission to be effectively applied to the NTN network, support optimizing the data transmission accuracy in the NTN network, and ensure the communication performance of the NTN network.

[0054] Optionally, in some embodiments, the TA adjustment amount is determined based on at least one of the following: receiving the first information and determining the TA adjustment amount based on the first information; determining the TA adjustment amount based on the timing adjustment strategy. Thus, the TA adjustment amount is determined in a timely and flexible manner, thereby supporting the timely determination of the target TA and ensuring the effect of data transmission optimization control.

[0055] Optionally, in some embodiments, if the TA adjustment amount is determined by the network device, the first information can be information sent by the terminal and used to trigger the network device to issue the TA adjustment amount, and the network device can receive the first information sent by the terminal and determine the TA adjustment amount in response to the first information; in addition, the network device can also determine the TA adjustment amount based on a protocol agreement, which is not limited.

[0056] Optionally, in some embodiments, if the TA adjustment amount is determined by the terminal, the first information can be information sent by the network device and used to indicate the TA adjustment amount to the terminal, and the terminal can receive the first information sent by the network device and determine the TA adjustment amount based on the indication of the network device; in addition, the terminal can also determine the TA adjustment amount based on a timing adjustment strategy (which can be related to the terminal implementation, which is not limited), which is not limited.

[0057] Optionally, in some embodiments, determining the target TA based on the TA adjustment amount can be adding the TA adjustment amount to the TA obtained by the last adjustment, and the accumulated TA can be taken as the target TA, which is not limited.

[0058] Optionally, in some embodiments, the target TA can be represented as "L", and the network device can determine it based on the following formula:

[0059] L = N TA (slot) + N TA_offset (symbol);

[0060] Wherein, N TA (slot) represents the time slot (slot), N TA_offset (symbol) represents the TA adjustment amount, and the TA adjustment amount is in units of symbols (symbol).

[0061] Optionally, in some embodiments, the terminal can determine based on the following formula:

[0062] L=N TA (slot)+N TA (symbol);

[0063] wherein, N TA (slot) represents in time slots (slot) units, N TA (symbol) represents in symbol (symbol) units, which is equivalent to determining based on the "timing adjustment strategy".

[0064] Step S203: controlling data transmission at the second time according to the initial CDRX state and the reference result.

[0065] Optionally, in some embodiments, the initial CDRX state can be activated or inactivated.

[0066] After determining the initial CDRX state and the reference result of whether the target TA corresponding to the second time is greater than the time unit, the data transmission at the second time can be controlled according to the initial CDRX state and the reference result. Optionally, in some embodiments, the terminal can determine to send or not to send data at the second time according to the initial CDRX state and the reference result, or the network device can determine to receive or not to receive data at the second time according to the initial CDRX state and the reference result.

[0067] In the embodiment, the initial connected mode discontinuous reception (CDRX) state related to the second time is determined based on the first time, wherein the first time is earlier than the second time, and it is determined whether the target timing advance (TA) corresponding to the second time is greater than a time unit to obtain a reference result, wherein the target TA is determined based on a TA adjustment amount, the determination time of the TA adjustment amount is later than the first time and earlier than the second time, and the data transmission at the second time is controlled according to the initial CDRX state and the reference result. Therefore, if the TA adjustment amount is determined between the first time and the second time, and the target TA is re-determined based on the TA adjustment amount, the data transmission control can be performed in combination with the reference result of whether the target timing advance TA is greater than the time unit and the initial CDRX state estimated at the first time, which can improve the accuracy of data transmission and ensure the communication performance.

[0068] Figure 3 Another flowchart of a transmission control method provided by the embodiment of the present disclosure.

[0069] As Figure 3 shown, the transmission control method comprises:

[0070] Step S301: determining an initial connected mode discontinuous reception (CDRX) state related to the second time instance based on a first time instance, where the first time instance is earlier than the second time instance.

[0071] Step S302: determining whether a target timing advance (TA) corresponding to the second time instance is greater than a time unit to obtain a reference result, where the target TA is determined based on a TA adjustment amount, and a determination time of the TA adjustment amount is later than the first time instance and earlier than the second time instance.

[0072] The description of S301-S302 can refer to the above embodiments, which will not be repeated here.

[0073] Step S303: in a case where the reference result is that the target TA is less than or equal to the time unit, controlling data transmission at the second time instance according to the initial CDRX state or an updated CDRX state, where the updated CDRX state is re-determined based on the target TA.

[0074] That is, if the reference result is that the target TA is less than or equal to the time unit, it means that the target TA will not cross a time unit, and in this case, since the target TA is relatively small, even if the terminal and the network device do not update the initial CDRX state based on the target TA, the accuracy of data transmission will not be affected. Therefore, whether the initial CDRX state is updated based on the target TA or not, the accuracy of data transmission can be ensured.

[0075] Therefore, in this embodiment, in a case where the reference result is that the target TA is less than or equal to the time unit, the data transmission at the second time instance can be controlled according to the initial CDRX state or the updated CDRX state, where the updated CDRX state is re-determined based on the target TA. For example, the network device can re-determine an updated CDRX state related to the second time instance based on the target TA, and use the updated CDRX state for data reception. The terminal can perform data transmission based on the initial CDRX state, and since the target TA is relatively small, whether the initial CDRX state is updated based on the target TA or not, the accuracy of data transmission can be ensured, and the transmission control can be effectively applied to the individualized communication scenario.

[0076] Optionally, in some embodiments, the initial CDRX state can be activated or inactivated.

[0077] Optionally, in some embodiments, in implementing the process of controlling the data transmission at the second time according to the initial CDRX state or the updated CDRX state, for example, in the case where the initial CDRX state or the updated CDRX state is active, the terminal can send data at the second time, and the network device can receive data at the second time. In the case where the initial CDRX state or the updated CDRX state is inactive, the terminal can not send data at the second time, and the network device can not receive data at the second time.

[0078] Step S304: In the case where the reference result is that the target TA is greater than the time unit, controlling the data transmission at the second time based on the second information and the initial CDRX state, wherein the second information is used to indicate whether to update the initial CDRX state with the target TA.

[0079] Optionally, in some embodiments, the second information is agreed by the protocol. The second information is used to indicate whether to update the initial CDRX state with the target TA. In this way, the protocol agreement is used to ensure that the terminal and the network device can use consistent CDRX states for the control of data transmission, and the flexibility of transmission control is improved.

[0080] That is to say, if the target TA is greater than (i.e., crosses) a time unit, the terminal and the network device can not be able to use consistent CDRX states for the control of data transmission. In this embodiment, in the case where the reference result is that the target TA is greater than the time unit, the data transmission at the second time can be controlled based on the second information and the initial CDRX state, wherein the second information is used to indicate whether to update the initial CDRX state with the target TA, that is, the data transmission at the second time is optimized.

[0081] Optionally, in some embodiments, in the case where the second information indicates not to update the initial CDRX state with the target TA, the data transmission at the second time is controlled according to the initial CDRX state.

[0082] That is to say, if the second information indicates not to update the initial CDRX state with the target TA, the terminal and the network device can both control the data transmission at the second time based on the initial CDRX state. For example, the terminal performs data sending at the second time based on the initial CDRX state. The network device performs data receiving at the second time based on the initial CDRX state. Thus, it is effectively ensured that the terminal and the network device can use consistent CDRX states for the control of data transmission, so as to ensure the data transmission effect.

[0083] Optionally, in some embodiments, in a case that the second information indicates to update the initial CDRX state by using the target TA, the target CDRX state is determined according to the target TA and the initial CDRX state, and the data transmission at the second time is controlled according to the target CDRX state.

[0084] That is, if the second information indicates to update the initial CDRX state by using the target TA, the terminal and the network device can both determine the target CDRX state according to the target TA and the initial CDRX state, and control the data transmission at the second time by using the target CDRX state. For example, the terminal performs data transmission at the second time based on the target CDRX state. The network device performs data reception at the second time based on the target CDRX state. Thus, it is effectively ensured that the terminal and the network device can control the data transmission by using the consistent target CDRX state, so as to ensure the data transmission effect.

[0085] In the embodiment, the initial connected mode discontinuous reception (CDRX) state related to the second time is determined based on the first time, the first time is earlier than the second time, and it is determined whether the target timing advance (TA) corresponding to the second time is greater than a time unit to obtain a reference result, the target TA is determined based on a TA adjustment amount, the determination time of the TA adjustment amount is later than the first time and earlier than the second time, and the data transmission at the second time is controlled according to the initial CDRX state and the reference result. Thus, if the TA adjustment amount is determined between the first time and the second time, and the target TA is re-determined based on the TA adjustment amount, the data transmission control can be performed in combination with the reference result of whether the target TA is greater than the time unit and the initial CDRX state estimated at the first time, which can improve the accuracy of data transmission and ensure the communication performance. In a case that the reference result is that the target TA is less than or equal to the time unit, the data transmission at the second time is controlled according to the initial CDRX state or an updated CDRX state, the updated CDRX state is re-determined based on the target TA. For example, the network device can re-determine the updated CDRX state related to the second time based on the target TA, and perform data reception by using the updated CDRX state. The terminal can perform data transmission based on the initial CDRX state. Thus, since the target TA is relatively small, the accuracy of data transmission can be ensured regardless of whether the initial CDRX state is updated based on the target TA, and the transmission control can be effectively applied to the individualized communication scenario.

[0086] Optionally, in some embodiments of the present disclosure, in implementing the above-mentioned process of determining the target CDRX state according to the target TA and the initial CDRX state, the target TA can also be used to re-determine an updated CDRX state related to the second time, and the target TA can be used to estimate a first reference CDRX state corresponding to a first reference time and a second reference CDRX state corresponding to a second reference time, wherein the first reference time is earlier than the second reference time, and the second time is between the first reference time and the second reference time; and the target CDRX state can be determined according to the updated CDRX state, the first reference CDRX state and the second reference CDRX state. In this way, the accuracy of the target CDRX state determination can be effectively improved, the accuracy of data transmission can be improved, and the communication performance can be improved.

[0087] The first reference time can be represented as "n-1", and the CDRX state corresponding to the first reference time can be referred to as the first reference CDRX state. The second reference time can be represented as "n+1", and the CDRX state corresponding to the second reference time can be referred to as the second reference CDRX state. The first reference time is earlier than the second reference time, and the second time is between the first reference time and the second reference time.

[0088] After determining the updated CDRX state, the first reference CDRX state and the second reference CDRX state, the target CDRX state can be determined according to the updated CDRX state, the first reference CDRX state and the second reference CDRX state.

[0089] Optionally, in some embodiments of the present disclosure, in implementing the process of determining the target CDRX state according to the updated CDRX state, the first reference CDRX state and the second reference CDRX state, the updated CDRX state can be determined as the target CDRX state when the updated CDRX state, the first reference CDRX state and the second reference CDRX state are the same. That is, if the updated CDRX state, the first reference CDRX state and the second reference CDRX state are the same, it means that the target CDRX state is relatively accurate, and the accuracy of data transmission can be ensured when the target CDRX state is used for data transmission.

[0090] For example, the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all "active", or the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all "inactive".

[0091] Optionally, in some embodiments of the present disclosure, in implementing the process of determining the target CDRX state according to the updated CDRX state, the first reference CDRX state and the second reference CDRX state, the updated CDRX state can be changed when the updated CDRX state, the first reference CDRX state and the second reference CDRX state are different, and the changed CDRX state is taken as the target CDRX state.

[0092] That is, if the updated CDRX state, the first reference CDRX state and the second reference CDRX state are different, the updated CDRX state can be changed, and the changed CDRX state is taken as the target CDRX state. For example, if the updated CDRX state is “activated”, it is updated to “not activated”, and if the updated CDRX state is “not activated”, it is updated to “activated”. In this way, the flexibility of data transmission control can be greatly improved, and the accuracy of data transmission can be improved.

[0093] For example, the updated CDRX state, the first reference CDRX state and the second reference CDRX state are different, for example, the updated CDRX state is “activated”, and the first reference CDRX state and the second reference CDRX state are “not activated”, or the updated CDRX state is “not activated”, and the first reference CDRX state and the second reference CDRX state are “activated”, and so on, which is not limited.

[0094] The above embodiments are illustrated as follows:

[0095] Taking the terminal or network device as an example of the execution subject of the transmission control method, the network device can configure the CDRX state, and the TA is adjusted between the “n-4ms” time (one optional example of the first time) and the “n” time (one optional example of the second time), and the adjusted TA (one optional example of the target TA) is greater than one time slot unit.

[0096] Optionally, in some embodiments, the terminal and the network device can agree to use the CDRX state estimated at the "n-4ms" time point for data transmission control. For example, the network device does not use the TA command word effective at the "n-4ms" time point to update the initial CDRX state estimated at the "n-4ms" time point (in this case, the initial CDRX state estimated at the "n-4ms" time point can be used without updating the initial CDRX state using the target TA determined based on the TA command word). Thus, the CDRX state used by the terminal and the network device at the "n" time point can be effectively ensured to be consistent. In addition, if the terminal determines that the timing deviation between the uplink frame and the downlink frame at the "n-4ms" time point to the "n" time point "crosses" a time slot due to the timing adjustment strategy, the terminal can maintain the CDRX active state obtained before the TA adjustment (in this case, the initial CDRX state estimated at the "n-4ms" time point can be used without updating the initial CDRX state using the target TA determined based on the TA command word).

[0097] Optionally, in some embodiments, the network device can use the following method to accurately determine the CDRX state. As shown in Figure 4 Figure 4 is a flowchart of a transmission control in an embodiment of the present disclosure. For example, the network device can perform the following steps: if the network device determines that the timing deviation between the uplink frame and the downlink frame corresponding to the "n" time point needs to be adjusted, and determines that the CDRX state before and after the adjustment will change, the CDRX state before the adjustment can be an optional example of the initial CDRX state described above, and the CDRX state after the adjustment can be an optional example of the updated CDRX state described above. The network device can refresh the CDRX state, and the refreshed CDRX state can be an optional example of the target CDRX state described above, so that the refreshed CDRX state is used for data reception at the "n" time point. For example:

[0098] (1) The network device can determine the following formula based on the following formula:

[0099] L = N TA (slot) + N TA_offset (symbol);

[0100] wherein N TA (slot) represents a time slot (slot), and N TA_offset (symbol) represents the TA adjustment amount, and the TA adjustment amount is in units of symbols (symbol).

[0101] The network device estimates the CDRX state "S n1 ​(n) (one optional example of the above-mentioned updating CDRX state), while estimating the CDRX state "S n2 (n-1) (one optional example of the above-mentioned first reference CDRX state), and the CDRX state "S n3 (n+1) (one optional example of the above-mentioned second reference CDRX state).

[0102] (2) If there is a valid TA command word adjusting TA from the time "n-4ms" to the time "n", the terminal can estimate whether to use S n1 (n), S n2 (n-1), S n3 (n+1) according to the adjusted TA (one optional example of the target TA).

[0103] (3) If there is a valid TA command word adjusting TA from the time "n-4ms" to the time "n", and S n1 (n), S n2 (n-1), S n3 (n+1) are inconsistent, the terminal can change the estimation result (i.e., change one optional example of the above-mentioned "updating CDRX state").

[0104] Optionally, in some embodiments, the terminal can accurately determine the CDRX state using the following method. As shown in Figure 5 , the terminal can determine the target CDRX state for the time "n" based on the TA that will take effect (one optional example of the target TA), and use the target CDRX state for data transmission at the time "n". Figure 5 is another flowchart of transmission control in an embodiment of the present disclosure. For example, the terminal can execute the flowchart if the terminal determines that the timing deviation between the uplink frame and the downlink frame corresponding to the time "n" is adjusted, and the adjustment causes the timing deviation to cross a slot, and determines that the CDRX state before and after the adjustment will change, wherein the CDRX state before the adjustment can be one optional example of the above-mentioned initial CDRX state, and the CDRX state after the adjustment can be one optional example of the above-mentioned updated CDRX state. The terminal can determine the target CDRX state for the time "n" based on the TA that will take effect (one optional example of the target TA), and use the target CDRX state for data transmission at the time "n". For example:

[0105] (1) The terminal can determine the target CDRX state for the time "n" based on the following formula:

[0106] L = 4ms + N TA (slot) + N TA (symbol);

[0107] wherein N TA (slot) represents the time slot (slot), and N TAindicates in units of symbol, which is equivalent to being determined based on the "timing adjustment strategy".

[0108] The terminal estimates the CDRX state "S u1 (T+L)" (one optional example of the above-mentioned updated CDRX state), the CDRX state "S u2 (T+L-1)" (one optional example of the above-mentioned first reference CDRX state), and the CDRX state "S u3 (T+L+1)" (one optional example of the above-mentioned second reference CDRX state).

[0109] (2) Before the time "T+L", the terminal estimates the timing deviation across slots between the uplink frame and the downlink frame at the time "T+L", and whether S u1 (T+L), S u2 (T+L-1), and S u3 (T+L+1) are consistent. That is, the terminal can adjust the TA before the time "T+L", and in addition, when the terminal estimates the CDRX state at the time "T+L-4ms", the terminal can estimate the CDRX state according to whether there is a timing deviation to be performed, whether the timing deviation is across slots, and whether S u1 (T+L), S u2 (T+L-1), and S u3 (T+L+1) are consistent. If they are not consistent across slots and S u1 (T+L), S u2 (T+L-1), and S u3 (T+L+1) are inconsistent, the CDRX state is estimated using the TA to be effective (one optional example of the above-mentioned target CDRX state).

[0110] (3) At the time "T+L", whether to send data is determined according to the estimated CDRX state (one optional example of the above-mentioned target CDRX state).

[0111] Therefore, the transmission control method provided in the embodiments of the present disclosure can effectively solve the technical problem of SRS and / or PCSI missing or false transmission caused by the misalignment of the CDRX state of the network device and the terminal in the large TA scenario, thereby ensuring the accuracy of SRS and / or PCSI transmission. Moreover, the transmission control method can effectively reduce the radio frequency channel overhead and greatly save the terminal power consumption.

[0112] Figure 6 FIG. 1 is a structural schematic diagram of a transmission control device provided in the embodiments of the present disclosure.

[0113] As Figure 6As shown, the transmission control device 60 comprises:

[0114] The first determination module 601 is configured to determine an initial connected mode discontinuous reception (CDRX) state related to the second time based on the first time, where the first time is earlier than the second time.

[0115] The second determination module 602 is configured to determine whether a target timing advance (TA) corresponding to the second time is greater than a time unit to obtain a reference result, where the target TA is determined based on a TA adjustment amount, and the determination time of the TA adjustment amount is later than the first time and earlier than the second time.

[0116] The control module 603 is configured to control data transmission at the second time according to the initial CDRX state and the reference result.

[0117] It should be noted that the foregoing explanation of the transmission control method embodiment is also applicable to the transmission control device of this embodiment, which will not be described here.

[0118] In this embodiment, the initial connected mode discontinuous reception (CDRX) state related to the second time is determined based on the first time, where the first time is earlier than the second time, and whether a target timing advance (TA) corresponding to the second time is greater than a time unit is determined to obtain a reference result, where the target TA is determined based on a TA adjustment amount, and the determination time of the TA adjustment amount is later than the first time and earlier than the second time, and data transmission at the second time is controlled according to the initial CDRX state and the reference result. Thus, if the TA adjustment amount is determined between the first time and the second time, and the target TA is re-determined based on the TA adjustment amount, the data transmission control can be performed in combination with the reference result of whether the target timing advance (TA) is greater than a time unit, and the initial CDRX state estimated at the first time, which can improve the accuracy of data transmission and ensure communication performance.
