[0144] In some embodiments, when the network configures the period, offset, and timer via Radio Resource Control (RRC) signaling, it can indicate whether the DTX and DRX functions are activated via cellDTXDRXactivationStatus. The network can also instruct the UE to activate or deactivate the cellDTX or DRX function via downlink DCI. The network configures cellDTRX-RNTI for the UE to determine whether to receive the DCI.

[0145] In some embodiments, the cellDTX and DRX states of the network are at the cell level and are the same for all UEs within the cell.

[0146] In some embodiments, the UE determines the start timer (cellDTX-DRX-onDurationTimer) based on the period and offset. During the timer's operation, the network is active, the UE listens to the downlink channel (Physical Downlink Control Channel (PDCCH)) and can send uplink transmissions.

[0147] In some embodiments, the network may not send downlink transmissions during cellDTX (i.e., when cellDTX-DRX-onDurationTimer is not running), but the UE will continue to listen to PDCCH if other DRX timers (wake-up, inactivity, retransmission timers) are running.

[0148] In some embodiments, during cell DRX, the UE does not send uplink transmissions, which may include scheduling requests (SR), configured uplink grants, and periodic / semi-persistent channel state information (CSI).

[0149] In some embodiments, UE uplink and downlink transmissions may be interrupted when cellDTX and DRX are active. If the UE needs to transmit data when cellDTX / DRX is active, the transmission will be delayed. UE uplink and downlink transmissions may not be periodic; their transmission locations and intervals may change. Currently, the network can only configure one set of DTX / DRX parameters and cannot dynamically adjust the DTX / DRX location, thus failing to dynamically match UE uplink and downlink transmissions.

[0150] Figure 2A is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. This method can be executed by the aforementioned communication system. As shown in Figure 2A, the method may include:

[0151] Step S2101: The network device sends the first information to the terminal.

[0152] In some embodiments, the terminal receives first information sent by a network device, but is not limited thereto. The terminal may also receive first information sent by other entities, in which case step S2101 may be omitted.

[0153] In some embodiments, the terminal obtains the first information specified by the protocol, in which case step S2101 can be omitted.

[0154] In some embodiments, the terminal obtains the first information from the upper layer(s), in which case step S2101 can be omitted.

[0155] In some embodiments, the first information may include at least one configuration information, which includes cell DTX parameters and / or cell DRX parameters.

[0156] In some embodiments, a configuration information corresponds to a set of cell DTX parameters and / or cell DRX parameters. For example, a configuration information corresponds to a set of cell DTX parameters, or a configuration information corresponds to a set of cell DRX parameters, or a configuration information corresponds to both cell DTX parameters and cell DRX parameters.

[0157] Step S2102: The network device sends a first instruction to the terminal.

[0158] In some embodiments, the terminal receives a first instruction sent by a network device, but is not limited thereto. The terminal may also receive a first instruction sent by another entity, in which case step S2102 may be omitted.

[0159] In some embodiments, the terminal obtains a first instruction defined by the protocol, in which case step S2102 can be omitted.

[0160] In some embodiments, the terminal obtains a first instruction from the upper layer(s), in which case step S2102 can be omitted.

[0161] In some embodiments, the first indication may be used to instruct the terminal to report at least one of the following:

[0162] Uplink transmission within the first time window;

[0163] Downlink transmission within the first time window;

[0164] The estimated transmission time of uplink transmissions within the first time window;

[0165] The expected transmission location of the uplink transmission within the first time window;

[0166] The estimated amount of uplink data to be transmitted within the first time window;

[0167] The estimated transmission time of downlink transmission within the first time window;

[0168] The expected transmission location of downlink transmission within the first time window;

[0169] The estimated amount of downlink data transmitted within the first time window.

[0170] For example, the first instruction is used to instruct the terminal to report at least one of the following: uplink transmission within a first time window, the estimated transmission time of the uplink transmission within the first time window, the estimated transmission location of the uplink transmission within the first time window, and the estimated data volume of the uplink transmission within the first time window.

[0171] For example, the first instruction is used to instruct the terminal to report at least one of the following: downlink transmission within a first time window, the estimated transmission time of the downlink transmission within the first time window, the estimated transmission location of the downlink transmission within the first time window, and the estimated data volume of the downlink transmission within the first time window.

[0172] For example, the first instruction is used to instruct the terminal to report at least one of the following: uplink transmission within a first time window, downlink transmission within a first time window, the estimated transmission time of the uplink transmission within a first time window, the estimated transmission location of the uplink transmission within a first time window, the estimated data volume of the uplink transmission within a first time window, the estimated transmission time of the downlink transmission within a first time window, the estimated transmission location of the downlink transmission within a first time window, and the estimated data volume of the downlink transmission within a first time window.

[0173] In some embodiments, the first time window includes a time window corresponding to the cell DTX status and / or cell DRX status determined based on configuration information.

[0174] In some embodiments, when the first information includes configuration information, the first time window includes a time window corresponding to the cell DTX status and / or cell DRX status determined based on the configuration information.

[0175] In some embodiments, when the first information includes multiple configuration information, the first time window may include a time window corresponding to the cell DTX state and / or cell DRX state determined based on all configuration information. Alternatively, the first time window may include a time window corresponding to the cell DTX state and / or cell DRX state determined based on some configuration information. For example, the first time window may include the next time window after the current time window determined based on one of the configuration information.

[0176] In some embodiments, the next time window can be an upcoming time window.

[0177] In some embodiments, different configuration information can determine different time windows.

[0178] In some embodiments, the first time window may be a pre-configured time window. For example, the first time window may include all time windows or the next time window after the current time window. In this case, step S2102 may be omitted.

[0179] Step S2103: The terminal predicts the data transmission within the first time window and obtains the prediction result.

[0180] In some embodiments, the terminal may predict the uplink transmissions within the first time window.

[0181] In some embodiments, the terminal may predict downlink transmissions within the first time window.

[0182] In some embodiments, the terminal can predict the uplink and downlink transmissions within the first time window.

[0183] In some embodiments, if the first indication is used to instruct the terminal to report uplink transmissions within a first time window, the terminal can predict uplink transmissions within the first time window but not downlink transmissions within the first time window; if the first indication is used to instruct the terminal to report downlink transmissions within a first time window, the terminal can predict downlink transmissions within the first time window but not uplink transmissions within the first time window; if the first indication is used to instruct the terminal to report both uplink and downlink transmissions within a first time window, the terminal can predict both uplink and downlink transmissions within the first time window.

[0184] In some embodiments, the first time window can be the next time window after the current time window, and the terminal can predict the data transmission in the next time window to obtain the prediction result.

[0185] In some embodiments, the first time window may also include multiple time windows, and the terminal may predict the data transmission within each time window to obtain the prediction result corresponding to each time window.

[0186] In some embodiments, the prediction result may include at least one of the following:

[0187] Is there data transmission within this first time window?

[0188] The transmission time of data within the corresponding time window;

[0189] The location of data transmission within the corresponding time window;

[0190] The amount of data transmitted.

[0191] In some embodiments, the transmission time can be the start or end time of data transmission. For example, if the time window corresponding to data transmission is [0ms, 500ms], the transmission time is 320ms.

[0192] In some embodiments, the transmission location can be a time period within a time window, including a start time and an end time. The transmission location of data transmission within a corresponding time window can be understood as the time period occupied by the data transmission within that time window.

[0193] In some embodiments, the terminal predicts the data transmission within the first time window, and the prediction result includes whether data transmission exists within the first time window.

[0194] In some embodiments, if data transmission occurs within the first time window, the prediction result further includes at least one of the following: the transmission time of the data transmission within the corresponding time window, the transmission location of the data transmission within the corresponding time window, and the data volume of the data transmission. If multiple data transmissions occur within the first time window, i.e., the first time window includes multiple time windows and data transmissions occur in multiple time windows, the prediction result may include the transmission time, transmission location, and data volume of each data transmission within the corresponding time window.

[0195] In some embodiments, the data transmission includes uplink transmission and / or downlink transmission.

[0196] In some embodiments, if the first indication is used to instruct the terminal to report uplink transmissions within the first time window, the prediction result may include at least one of the following: whether there is an uplink transmission within the first time window, the transmission time of the uplink transmission within the corresponding time window, the transmission location of the uplink transmission within the corresponding time window, and the amount of data transmitted uplinks.

[0197] In some embodiments, if the first indication is used to instruct the terminal to report downlink transmissions within the first time window, the prediction result may include at least one of the following: whether downlink transmissions exist within the first time window, the transmission time of downlink transmissions within the corresponding time window, the transmission location of downlink transmissions within the corresponding time window, and the amount of uplink data transmitted.

[0198] In some embodiments, if the first indication is used to instruct the terminal to report uplink and downlink transmissions within the first time window, the prediction result may include at least one of the following: whether uplink and downlink transmissions exist within the first time window, the transmission time of uplink and downlink transmissions within the corresponding time window, the transmission location of uplink and downlink transmissions within the corresponding time window, and the amount of data transmitted in the uplink and downlink transmissions.

[0199] In some embodiments, if data transmission occurs within the first time window, the prediction result may further include a second indication indicating the type of data transmission, which is either uplink or downlink transmission. For example, the prediction result may include at least one of the following: data transmission occurs within the first time window; the type of data transmission is uplink; the transmission time of the uplink transmission within the corresponding time window; the transmission location of the uplink transmission within the corresponding time window; and the amount of data transmitted uplink.

[0200] In some embodiments, where the first time window includes multiple time windows, the prediction result may also include an identifier of a time window in which data transmission occurs.

[0201] In some embodiments, the identifier of a time window can be a time window number, which can be determined based on the reporting time of the prediction result. The first time window after the prediction result is reported is numbered 0 or 1, the second time window after the prediction result is reported is numbered 1 or 2, and so on, so that the number of each time window can be determined and the identifier of each time window can be obtained.

[0202] It should be noted that if no data transmission occurs within a time window, the identifier for that time window will not be reported. For example, if no data transmission occurs within the second time window after the prediction result is reported, the identifier for the second time window will not be reported, and the identifier for the third time window where data transmission occurs will be 1 or 2.

[0203] In some embodiments, where the first information includes multiple configuration information, the prediction result may further include a third indication, which is used to indicate the first configuration information among the multiple configuration information. The first time window is determined by the first configuration information, and the time windows determined by different configuration information are different.

[0204] In some embodiments, when the first information includes multiple configuration information, there are also multiple time windows determined based on the multiple configuration information, i.e., the first time window includes multiple time windows. In this case, the prediction result may include a third indication to indicate the first configuration information used to determine the first time window. Different third indications may indicate different configuration information, corresponding to different time windows. After receiving the prediction result, the network device can activate or deactivate the configuration information corresponding to the time window based on the data transmission situation of each time window.

[0205] It should be noted that determining the configuration information for the first time window can be understood as determining the cell DTX parameters and / or cell DRX parameters for the first time window.

[0206] In some embodiments, the third indication may also be referred to as a parameter identification indication.

[0207] In some embodiments, the terminal can predict the data transmission within the first time window based on parameters configured in the configuration information.

[0208] In some embodiments, the terminal can predict different types of data transmission within the first time window based on the parameter types configured in the configuration information.

[0209] In some embodiments, when the cell DTX parameters are configured in the configuration information, downlink transmission within the first time window is predicted; when the cell DRX parameters are configured in the configuration information, uplink transmission within the first time window is predicted.

[0210] It should be noted that, with the cell DTX and DRX parameters configured in this configuration information, uplink and / or downlink transmissions within the first time window are predicted.

[0211] In some embodiments, the terminal can predict data transmission within a first time window using AI. For example, the terminal can predict data transmission within the first time window using AI functions or AI models. The AI ​​functions and AI models can be pre-trained functions and models from related technologies, which will not be elaborated further here.

[0212] Step S2104: The terminal sends the prediction result to the network device.

[0213] In some embodiments, the terminal predicts the data transmission within a first time window, and after obtaining the prediction result, it can send the prediction result to the network device.

[0214] In some embodiments, if the first time window is the next time window after the current time window, and there is data transmission within the next time window, the prediction result for the next time window is sent to the network device; if there is no data transmission within the next time window, the prediction result does not need to be sent to the network device, and step S2104 can be omitted.

[0215] Step S2105: The network device determines whether to activate or deactivate the configuration information based on the prediction result.

[0216] In some embodiments, after receiving the prediction result sent by the terminal, the network device determines whether to activate or deactivate the configuration information corresponding to each time window in the prediction result.

[0217] In some embodiments, the network device may determine whether to activate or deactivate the configuration information corresponding to the time window based on at least one of the prediction results corresponding to the time window.

[0218] For example, if the prediction result indicates that there is uplink transmission within the time window, the configuration information corresponding to the time window uses pre-configured cell DRX parameters, and the cell DRX parameters configured in the configuration information are currently not activated, then it is determined to activate the configuration information; if the prediction result indicates that there is downlink transmission within the time window, the configuration information corresponding to the time window uses pre-configured cell DRX parameters, and the cell DRX parameters configured in the configuration information are currently activated, then it is determined to deactivate the configuration information.

[0219] For example, network devices determine the rationality of configured cell DTX and / or cell DRX parameters based on the data transmission time and / or location in the prediction result. If the configuration is rational, the corresponding configuration information can be activated; if the configuration is unreasonable, the corresponding configuration information can be deactivated. Network devices can also determine whether the configured cell DTX and / or cell DRX parameters meet the requirements based on the data transmission volume in the prediction result. If the data transmission volume exceeds a data volume threshold, the cell DTX and / or cell DRX parameters are deactivated; if the data transmission volume is less than or equal to the data volume threshold, the cell DTX and / or cell DRX parameters are activated. The data volume threshold can be the maximum data transmission volume that the configured cell DTX and / or cell DRX parameters can provide.

[0220] It should be noted that for each time window in the prediction results, the network device can determine whether to activate or deactivate the configuration information corresponding to that time window.

[0221] Step S2106: The network device sends the second information to the terminal.

[0222] In some embodiments, the second information may include at least one of the following: a fourth indication and a first identifier, wherein the fourth indication is an activation indication or a deactivation indication, and the first identifier is used to indicate configuration information, and different configuration information corresponds to different first identifiers.

[0223] In some embodiments, the first identifier may indicate configuration information that needs to be switched from an active state. For example, if the configuration information needs to be switched from an active state to a deactivated state, the network device may send second information to the terminal to indicate that the configuration information is switched from an active state to a deactivated state.

[0224] It should be noted that if the activation status of the configuration information does not need to be switched, the network device may not send the first identifier corresponding to the configuration information to the terminal. For example, if the configuration information is currently in an active state, and the network device determines that the configuration information needs to be activated, then the second information will not include the first identifier corresponding to the configuration information.

[0225] It should also be noted that if the configuration information that needs to be switched includes multiple items, the second information may include multiple first identifiers. Different first identifiers indicate different configuration information, and each first identifier can be bound to a fourth indicator to indicate whether to activate or deactivate the configuration information indicated by the first identifier.

[0226] In some embodiments, the network device can carry the second information via DCI, and the terminal can receive the DCI via cellDTRX-RNTI.

[0227] Step S2107: The terminal activates or deactivates the configuration information corresponding to the first identifier based on the second information.

[0228] In some embodiments, after receiving the second information sent by the network device, the terminal activates or deactivates the configuration information indicated by the first identifier according to the fourth indication bound to the first identifier for each first identifier in the second information. For example, the first identifiers include 1, 2, and 3. The fourth indication bound to 1 is an activation indication, the fourth indication bound to 2 is a deactivation indication, and the fourth indication bound to 3 is an activation indication. The terminal can activate the configuration information indicated by 1 and 3, and deactivate the configuration information indicated by 2.

[0229] It should be noted that activating configuration information can be understood as activating a set of cell DTX parameters and / or cell DRX parameters configured by that configuration information, and deactivating configuration information can be understood as deactivating a set of cell DTX parameters and / or cell DRX parameters configured by that configuration information.

[0300] In some embodiments, this disclosure provides a method for UE-assisted dynamic control of Network Energy Saving (NES) status, which can reduce UE transmission latency caused by cellDTX / DRX.

[0301] In some embodiments, the UE receives one or more sets of DTX and / or DRX parameters sent by the network. The UE predicts whether there will be transmission within the time window of the cellDTX and / or DRX state determined by the DTX and / or DRX parameters, and sends the prediction result to the network. The network sends a first indication to the UE, instructing the UE to activate or deactivate which set of cellDTX and / or DRX parameters.

[0302] In some embodiments, the UE can use AI to predict whether there will be uplink or downlink transmissions within the time window of the corresponding cellDTX and / or DRX state.

[0303] In some embodiments, the network may instruct the UE to report only uplink transmissions within the time window, or only downlink transmissions within the time window, or report both uplink and downlink transmissions within the time window.

[0304] In some embodiments, the UE may report whether there are uplink or downlink transmissions within a corresponding window. It may also additionally indicate the estimated time and location of the uplink and / or downlink transmissions within the corresponding window, as well as the amount of data.

[0305] In some embodiments, if the UE reports uplink or downlink transmissions within a time window, the UE needs to additionally indicate whether there is an uplink or downlink transmission.

[0306] In some embodiments, the UE determines whether to report uplink transmission, downlink transmission, or both based on the configured parameter type.

[0307] In some embodiments, if the cellDTX parameter is configured, the UE predicts downlink transmission within the corresponding time window.

[0308] In some embodiments, if the cellDRX parameter is configured, the UE predicts uplink transmission within the corresponding time window.

[0309] In some embodiments, if cellDTX and DRX parameters are configured, the UE predicts uplink and / or downlink transmissions within the corresponding time window.

[0310] In some embodiments, the UE can predict and report uplink and downlink transmissions within the next time window.

[0311] In some embodiments, if there are no uplink or downlink transmissions in the next time window, the UE does not report any information.

[0312] In some embodiments, the next time window is the next time window that is about to arrive.

[0313] In some embodiments, when the network provides multiple sets of DRX and DRX parameters, the time window position determined by the UE may be different based on different parameters. The UE indicates in the report which set of parameters the time window is determined based on, and indicates this through parameter identifiers.

[0314] In some embodiments, the UE can predict and report uplink and downlink transmissions within the next one or more time windows.

[0315] In some embodiments, the UE may only report the time window number where uplink and downlink transmissions occur. If there are no uplink or downlink transmissions within a certain time window, the time window number will not be reported. The time window number is determined based on the reporting time, with the first window after the reporting occurs being either the first or the zeroth window.

[0316] In some embodiments, when the network provides multiple sets of DRX and DRX parameters, the time window position determined by the UE may be different based on different parameters. The UE indicates in the report which set of parameters the time window is determined based on, and indicates this through parameter identifiers.

[0317] In some embodiments, the network sends a first indication to the UE, which carries an activation indication or deactivation indication and a DTX / DRX parameter identifier. The UE determines which set of parameters to activate or deactivate based on the identifier.

[0318] In some embodiments, the first indication may be carried using a DCI, which the UE may receive via cellDTRX-RNTI.

[0319] In some embodiments, the network determines whether to activate or deactivate the cellDTX or DRX parameters based on the uplink and downlink transmission information reported by the UE.
