[0028] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0030] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0031] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 For entities other than the above, the number and form of each entity are arbitrary, and the connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0032] Embodiments of the present disclosure may 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), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0033] In the related art, the non-terrestrial network may have a timing advance (TA) greater than one time unit (e.g., time slot), so the uplink time slot timing on the terminal side needs to be sent at least one time unit in advance relative to the downlink time slot timing. In the scenario of configured connected mode discontinuous reception (CDRX), when data needs to be transmitted at time n (e.g., sounding reference signal (SRS), or periodic channel state information (PCSI)), the terminal needs to decide whether to send data based on the CDRX state estimated at time n at time n-4ms, and the network device needs to decide whether to receive data based on the CDRX state estimated at time n at time n-4ms. In this way, if there is a TA command word (used to determine TA) between time n-4ms and time n, if the timing deviation (ie, TA) between the uplink frame and the downlink frame spans a time unit, the terminal may not be able to obtain the CDRX state in time, so that there is a difference between the CDRX state determined by the network side and the terminal, resulting in the data not being able to be transmitted correctly, affecting the communication performance.

[0034] In order to solve the above technical problems, the disclosed embodiment provides a transmission control method, which determines the initial connection mode discontinuous reception CDRX state related to the second moment based on the first moment, wherein the first moment is earlier than the second moment, and determines whether the target timing advance TA corresponding to the second moment is greater than the time unit, and obtains a reference result, wherein the target TA is determined based on the TA adjustment amount, and the determination time of the TA adjustment amount is later than the first moment and earlier than the second moment, and the data transmission at the second moment is controlled according to the initial CDRX state and the reference result. Therefore, if the TA adjustment amount is determined between the first moment and the second moment, and the target TA is re-determined based on the TA adjustment amount, the data transmission control can be combined 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 moment, so as to improve the accuracy of data transmission and ensure communication performance.

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

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

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

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

[0039] Figure 2 A flow chart of a transmission control method provided by an embodiment of the present disclosure.

[0040] like Figure 2 As shown, the transmission control method includes:

[0041] Step S201: Based on a first moment, determine an initial connected mode discontinuous reception CDRX state associated with a second moment, wherein the first moment is earlier than the second moment.

[0042] The first moment refers to the moment when the CDRX state estimation is performed. When the CDRX state estimation is performed, the CDRX state at the second moment may be estimated. Optionally, in some embodiments, the first moment is earlier than the second moment, and a certain time interval may be provided between the first moment and the second moment. The time interval may be, for example, 4 milliseconds (ms), without limitation. Optionally, in some embodiments, the second moment may be expressed as n, and the first moment may be expressed as n-4ms, without limitation.

[0043] In the following examples, the time interval between the first moment and the second moment may be 4 ms. Of course, it may also be applicable to any other possible time intervals without limitation.

[0044] Optionally, in some embodiments, the CDRX state related to the time "n" may be estimated at the time "n-4ms", and the estimated CDRX state may be referred to as the initial CDRX state. The initial CDRX state is used to control the transmission (such as sending and / or receiving) of data at the time "n", and there is no limitation on this.

[0045] In an embodiment of the present disclosure, the duration between the first moment and the second moment can be determined according to the subcarrier spacing of the transmission frame. For example, when the subcarrier spacing is 15 kmz, the duration between the first moment and the second moment is 4 ms.

[0046] In the embodiments of the present disclosure, based on the first moment, it can be understood as at the first moment.

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

[0048] Optionally, in some embodiments, the terminal may receive, at the first moment, an initial CDRX state configured by the network device for the second moment, which is not limited.

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

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

[0051] In an embodiment of the present disclosure, the reference result may include that the target timing advance TA is greater than the time unit, or that the target TA is less than or equal to the time unit.

[0052] In some communication scenarios, between the first moment and the second moment, the TA may be adjusted, and the adjusted TA may be referred to as the target TA. The target TA may be greater than (i.e., spanning) a time unit. In addition, if the target TA is re-determined, the terminal and the network device may not both 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 may use the initial CDRX state to send data, and the network device may use the updated CDRX state to receive data). Therefore, the terminal and the network device may not be able to use a consistent CDRX state to control data transmission. Therefore, in the embodiment of the present disclosure, after the target TA is re-determined, it can be based on the reference result of whether the target TA corresponding to the second moment is greater than the time unit to ensure that the terminal and the network device use a consistent CDRX state to control data transmission, thereby optimizing the data transmission effect.

[0053] Optionally, in some embodiments, the time unit includes: a time slot. That is, the time unit may be a time slot. Thus, the optimization control mechanism for data transmission can be effectively applied to large TA scenarios, and generally the accumulated TA in the NTN network is greater than a time slot. Therefore, the optimization control mechanism for data transmission can be further effectively applied to the NTN network, supporting the optimization of data transmission accuracy in the NTN network and ensuring 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 can be 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 may be information sent by the terminal and used to trigger the network device to send the TA adjustment amount. The network device may 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 may 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 may be information sent by the network device and used to indicate the TA adjustment amount to the terminal. The terminal may 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 may also determine the TA adjustment amount based on a timing adjustment strategy (wherein the timing adjustment strategy may be related to the terminal implementation and is not limited thereto). There is no limitation on this.

[0057] Optionally, in some embodiments, the target TA is determined based on the TA adjustment amount, and the TA adjustment amount may be accumulated on the TA obtained by the last adjustment, and the accumulated TA may be used as the target TA, and there is no limitation on this.

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

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

[0060] Among them, N TA (slot) means the unit is time slot, N TA_offset (symbol) represents the TA adjustment amount, and the TA adjustment amount is in the unit of symbol (symbol).

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

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

[0063] Among them, N TA (slot) means the unit is time slot, N TA (symbol) means that the unit is symbol, which is equivalent to being determined based on the "timing adjustment strategy".

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

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

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

[0067] In this embodiment, the initial connection mode discontinuous reception CDRX state related to the second moment is determined based on the first moment, wherein the first moment is earlier than the second moment, and whether the target timing advance TA corresponding to the second moment is greater than the time unit is determined, and a reference result is obtained, wherein the target TA is determined based on the TA adjustment amount, and the determination time of the TA adjustment amount is later than the first moment and earlier than the second moment, and the data transmission at the second moment is controlled according to the initial CDRX state and the reference result. Therefore, if the TA adjustment amount is determined between the first moment and the second moment, 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 moment, so as to improve the accuracy of data transmission and ensure communication performance.

[0068] Figure 3 A flowchart of another transmission control method provided by an embodiment of the present disclosure.

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

[0070] Step S301: Based on a first moment, determine an initial connected mode discontinuous reception CDRX state associated with a second moment, wherein the first moment is earlier than the second moment.

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

[0072] For the description of S301 - S302 , please refer to the above embodiment, which will not be repeated here.

[0073] Step S303: When the reference result is that the target TA is less than or equal to the time unit, data transmission at the second moment is controlled according to the initial CDRX state or the updated CDRX state, wherein the updated CDRX state is re-determined based on the target TA.

[0074] That is to say, 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. 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, it will not affect the accuracy of data transmission. Therefore, regardless of whether the initial CDRX state is updated based on the target TA, the accuracy of data transmission can be ensured.

[0075] Therefore, in this embodiment, when the reference result is that the target TA is less than or equal to the time unit, the data transmission at the second moment can be controlled according to the initial CDRX state or the updated CDRX state, wherein the updated CDRX state is re-determined based on the target TA. For example, the network device can redetermine the updated CDRX state related to the second moment based on the target TA, and use the updated CDRX state to receive data. The terminal can send data based on the initial CDRX state. Since the target TA is relatively small, regardless of whether the initial CDRX state is updated based on the target TA, the accuracy of data transmission can be ensured, and the transmission control can be effectively applied to personalized communication scenarios.

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

[0077] Optionally, in some embodiments, in the process of controlling the data transmission at the second moment according to the initial CDRX state or the updated CDRX state, for example: when the initial CDRX state or the updated CDRX state is activated, the terminal may send data at the second moment, and the network device may receive data at the second moment. When the initial CDRX state or the updated CDRX state is inactive, the terminal may not send data at the second moment, and the network device may not receive data at the second moment.

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

[0079] Optionally, in some embodiments, the second information is agreed upon by the protocol. The second information is used to indicate whether to use the target TA to update the initial CDRX state. Thus, based on the protocol agreement, it is achieved to ensure that the terminal and the network device can use the consistent CDRX state to control data transmission, thereby improving the flexibility of transmission control.

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

[0081] Optionally, in some embodiments, when the second information indicates that the target TA is not used to update the initial CDRX state, data transmission at the second moment is controlled according to the initial CDRX state.

[0082] That is to say, if the second information indicates that the target TA is not used to update the initial CDRX state, the terminal and the network device can both control the data transmission at the second moment based on the initial CDRX state. For example, the terminal sends data at the second moment based on the initial CDRX state. The network device receives data at the second moment based on the initial CDRX state. This effectively ensures that the terminal and the network device can use the consistent CDRX state to control data transmission, so as to ensure the data transmission effect.

[0083] Optionally, in some embodiments, when the second information indicates to use the target TA to update the initial CDRX state, the target CDRX state is determined according to the target TA and the initial CDRX state, and the data transmission at the second moment is controlled according to the target CDRX state.

[0084] That is to say, if the second information indicates that the initial CDRX state is updated using the target TA, the terminal and the network device can both determine the target CDRX state based on the target TA and the initial CDRX state, and use the target CDRX state to control data transmission at the second moment. For example, the terminal sends data at the second moment based on the target CDRX state. The network device receives data at the second moment based on the target CDRX state. This effectively ensures that the terminal and the network device can use the consistent target CDRX state to control data transmission, so as to ensure the data transmission effect.

[0085] In this embodiment, the initial connection mode discontinuous reception CDRX state related to the second moment is determined based on the first moment, wherein the first moment is earlier than the second moment, and whether the target timing advance TA corresponding to the second moment is greater than the time unit is determined, and a reference result is obtained, wherein the target TA is determined based on the TA adjustment amount, and the determination time of the TA adjustment amount is later than the first moment and earlier than the second moment, and the data transmission at the second moment is controlled according to the initial CDRX state and the reference result. Therefore, if the TA adjustment amount is determined between the first moment and the second moment, 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 moment, so as to improve the accuracy of data transmission and ensure communication performance. When the reference result is that the target TA is less than or equal to the time unit, the data transmission at the second moment is controlled according to the initial CDRX state or the updated CDRX state, wherein 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 moment based on the target TA, and use the updated CDRX state for data reception. The terminal can send data based on the initial CDRX state. Therefore, 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 personalized communication scenarios.

[0086] Optionally, in some embodiments of the present disclosure, in the process of realizing the above-mentioned "determining the target CDRX state according to the target TA and the initial CDRX state", it is also possible to re-determine the updated CDRX state related to the second moment according to the target TA, and estimate the first reference CDRX state and the second reference CDRX state according to the target TA, wherein the first reference CDRX state corresponds to the first reference moment, the second reference CDRX state corresponds to the second reference moment, the first reference moment is earlier than the second reference moment, and the second moment is between the first reference moment and the second reference moment; determine the target CDRX state according to the updated CDRX state, the first reference CDRX state and the second reference CDRX state. In this way, the accuracy of determining the target CDRX state can be effectively improved, the accuracy of data transmission can be improved, and the communication performance can be improved.

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

[0088] After the update CDRX state, the first reference CDRX state and the second reference CDRX state are determined, the target CDRX state may be determined according to the update CDRX state, the first reference CDRX state and the second reference CDRX state.

[0089] Optionally, in some embodiments of the present disclosure, in 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 may 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 to say, if the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all the same, it means that the target CDRX state is more accurate, and when the target CDRX state is used for data transmission, the accuracy of data transmission can be ensured.

[0090] For example, “the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all the same”, for example, the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all “activated”, or the updated CDRX state, the first reference CDRX state and the second reference CDRX state are all “inactivated”.

[0091] Optionally, in some embodiments of the present disclosure, in the process of determining the target CDRX state based on the updated CDRX state, the first reference CDRX state and the second reference CDRX state, the updated CDRX state may 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 used as the target CDRX state.

[0092] That is to say, 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 used as the target CDRX state. For example, if the updated CDRX state is "activated", it is updated to "inactivated", and if the updated CDRX state is "inactivated", 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”, while the first reference CDRX state and the second reference CDRX state are “inactivated”, or the updated CDRX state is “inactivated”, while the first reference CDRX state and the second reference CDRX state are “activated”, and so on, without limitation.

[0094] The examples for the above embodiment are as follows:

[0095] Taking the execution subject of the transmission control method as an example, the network device can configure the CDRX state, and perform TA adjustment between the "n-4ms" moment (an optional example of the first moment) and the "n" moment (an optional example of the second moment), and the adjusted TA (an 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 control data transmission using the CDRX state estimated at the time "n-4ms" based on the agreement of the protocol. For example, the network device does not use the effective TA command word from the time "n-4ms" to the time "n" to estimate the CDRX state (in this case, it is equivalent to using the initial CDRX state estimated at the time "n-4ms" instead of using the target TA re-determined based on the effective TA command word to update the initial CDRX state). This can effectively ensure that the CDRX state used by the terminal and the network device at the time "n" is consistent. In addition, if the terminal is from the time "n-4ms" to the time "n", due to the timing adjustment strategy determining that the timing deviation between the uplink frame and the downlink frame "crosses" a time slot, the terminal can maintain the CDRX activation state obtained before the TA adjustment (in this case, it is equivalent to using the initial CDRX state estimated at the time "n-4ms" instead of using the re-determined target TA to update the initial CDRX state).

[0097] Optionally, in some embodiments, the network device may use the following method to accurately determine the CDRX state. Figure 4 As shown, Figure 4 It is a flow chart of a transmission control in an embodiment of the present disclosure. It can be executed, for example, by a network device. If the network device determines that the timing deviation between the uplink frame and the downlink frame corresponding to the "n" moment is adjusted, and determines that the CDRX state before and after the adjustment will change, wherein the CDRX state before the adjustment can be an optional example of the above-mentioned initial CDRX state, and the CDRX state after the adjustment can be an optional example of the above-mentioned updated CDRX state. The network device can refresh the CDRX state, and the CDRX state obtained by the refresh can be an optional example of the above-mentioned target CDRX state, so as to use the refreshed CDRX state to receive data at the "n" moment. Examples are as follows:

[0098] (1) Network devices can be determined based on the following formula:

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

[0100] Among them, N TA (slot) means the unit is time slot, N TA_offset (symbol) represents the TA adjustment amount, and the TA adjustment amount is in the unit of symbol (symbol).

[0101] The network device estimates the CDRX status "S" at time "n" n1(n)” (an optional example of updating the CDRX state as described above), and at the same time estimating the CDRX state “S n2 (n-1)" (an optional example of the first reference CDRX state described above), and the CDRX state "S" at the "n+1" moment n3 (n+1)" (an optional example of the second reference CDRX state mentioned above).

[0102] (2) If there is a valid TA command word to adjust the TA between time "n-4ms" and time "n", then estimate whether to use S according to the adjusted TA (an optional example of the target TA). n1 (n), S n2 (n-1), S n3 (n+1).

[0103] (3) If there is a valid TA command word to adjust TA between time "n-4ms" and time "n", if S n1 (n), S n2 (n-1), S n3 (n+1) If the three are inconsistent, the estimated result can be changed (i.e., an optional example of changing the above-mentioned "update CDRX status").

[0104] Optionally, in some embodiments, the terminal may use the following method to accurately determine the CDRX state. Figure 5 As shown, Figure 5 It is a flowchart of another transmission control in the embodiment of the present disclosure. It can be executed, for example, by a terminal. If the terminal determines that the timing deviation between the uplink frame and the downlink frame corresponding to the "n" moment is adjusted, and the adjustment causes the timing deviation to cross the time slot, and determines that the CDRX state before and after the adjustment will change, wherein the CDRX state before the adjustment can be an optional example of the above-mentioned initial CDRX state, and the CDRX state after the adjustment can be an optional example of the above-mentioned updated CDRX state. Then the terminal can determine the target CDRX state for the "n" moment based on the TA that is about to take effect (an optional example of the target TA), so as to use the target CDRX state to send data at the "n" moment. An example is given below:

[0105] (1) The terminal can be determined based on the following formula:

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

[0107] Among them, N TA (slot) means the unit is time slot, N TA(symbol) means that the unit is symbol, which is equivalent to being determined based on the "timing adjustment strategy".

[0108] The terminal estimates the CDRX status "S" at the time "T+L" u1 (T+L)” (an optional example of updating the CDRX state as described above), and at the same time estimating the CDRX state “S u2 (T+L-1)" (an optional example of the first reference CDRX state mentioned above), and the CDRX state "S" at the time "T+L+1" u3 (T+L+1)" (an optional example of the above-mentioned second reference CDRX state).

[0109] (2) Before the “T+L” time, estimate the timing deviation between the uplink frame and the downlink frame at the “T+L” time across time slots, and S u1 (T+L), S u2 (T+L-1) and S u3 (T+L+1) is consistent. That is to say, the terminal can adjust TA before the "T+L" time. In addition, when the terminal estimates the CDRX state at the "T+L-4ms" time, it can adjust the TA based on whether there is a timing deviation to be executed, and the timing deviation spans time slots, and S u1 (T+L), S u2 (T+L-1) and S u3 (T+L+1) is consistent to estimate the CDRX state. u1 (T+L), S u2 (T+L-1) and S u3 (T+L+1) If the three are inconsistent, the TA that will take effect soon is used to estimate the CDRX state (an optional example of the above target CDRX state).

[0110] (3) At time "T+L", determine whether to send data based on the estimated CDRX state (an optional example of the above-mentioned target CDRX state).

[0111] Therefore, the transmission control method provided in the embodiment of the present disclosure can effectively solve the technical problem that the CDRX states of the network device and the terminal are not aligned in the large TA scenario, resulting in the omission or mistransmission of SRS and / or PCSI, thereby ensuring the accuracy of SRS and / or PCSI transmission. It can also effectively reduce the RF channel overhead and save terminal power consumption to a large extent.

[0114] The first determining module 601 is used to determine an initial connected mode discontinuous reception CDRX state related to a second moment based on a first moment, wherein the first moment is earlier than the second moment.

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

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

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

Therefore, if the TA adjustment amount is determined between the first moment and the second moment, 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 moment, so as to improve the accuracy of data transmission and ensure communication performance.
