[0159] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0160] To better understand the embodiments of this disclosure, the following exemplary embodiment will be used to further illustrate the technical solution of this disclosure:

[0161] In one embodiment, under the direct activation mode of Scell, the start time of the Scell ​​inactive timer is based on the current time plus an offset value (the first offset value, corresponding to the time offset of this disclosure), which is at least related to the duration of processing RRC messages.

[0162] In one embodiment, the processing time for RRC messages can be converted to a statistical unit of slots. For example, the conversion process is to divide the processing time by the slot length (NR slot length), which yields the processing time in slot units; and the slot length is related to the numberology of the activated scell.

[0163] In one embodiment, enabling the Scell ​​inactive timer includes starting and restarting.

[0164] In one embodiment, the current time is the time slot n in which the Scell ​​direct activation message (RRC message in this disclosure) is received;

[0165] As an example, Slot n can be the last slot to receive a PDSCH transmission carrying an RRC message.

[0166] In one embodiment, the Scell ​​direct activation method includes:

[0167] The first method is direct SCell activation at SCell addition (i.e., directly activating the SCell using the configuration information in the RRC message);

[0168] The second method is direct SCell activation at handover (i.e., directly activating the SCell using the configuration information in the handover message); and

[0169] The third method is direct SCell Activation at RRC Resume (i.e., directly activating the SCell using the configuration information in the RRC resume message).

[0170] In one embodiment, the first offset value may be related to the duration of processing the RRC message. For example, the duration of processing the RRC message includes the processing delay duration of receiving the RRC message (corresponding to the first processing duration).

[0171] In one embodiment, the corresponding first processing time can be a value agreed upon in the protocol.

[0172] In one embodiment, the processing delay duration for RRC messages can be defined for the first method, the second method, and the third method respectively. That is, the processing delay duration for RRC messages corresponding to the first method, the second method, and the third method can be configured to be the same or different to achieve flexible duration configuration.

[0173] In one embodiment, for both the first and third methods, the first offset value is at least related to the duration of processing the RRC message. For example, the duration of processing the RRC message includes the processing delay of receiving the RRC message (first processing duration) and the delay of sending a response message of the RRC message back to the network (second processing duration).

[0174] In one embodiment, the processing delay for receiving the RRC message (corresponding to the first processing duration in this disclosure) is T. RRC_Process This is the RRC processing delay defined in clause 12 of TS 38.331.

[0175] In one embodiment, the delay in sending the response message of the RRC message back to the network (corresponding to the second processing duration in this disclosure) is the time interval from the processing delay of receiving the RRC message until the response message of the RRC message can be sent; here, the time interval can be the duration from time X until the response message of the RRC message is sent; where X = slot n + T RRC_Process / NR slot length; slot n is the last slot from which a PDSCH transmission carrying an RRC message was received, T RRC_Process The NR slot length is the duration of the NR time slot, which is the duration of the received RRC message.

[0176] In one embodiment, for the first method, the received RRC message is an RRC connection reconfiguration message; while the RRC response message fed back to the network (the response message of the RRC message described in this disclosure) is an RRC connection reconfiguration completion message.

[0177] In one embodiment, for the third method, the received RRC message is an RRC connection recovery message; while the RRC response message sent back to the network is an RRC connection recovery complete message.

[0178] In one embodiment, for the second approach, the offset value is at least related to the duration of processing the RRC message. Exemplarily, the duration of processing the RRC message includes the processing delay upon receiving the RRC message (first processing duration), the handover interruption duration (third processing duration), and the TA processing duration (fourth processing duration).

[0179] In one embodiment, the processing delay for receiving the RRC message (corresponding to the first processing duration in this disclosure) is T. RRC_Process This is the RRC processing delay defined in clause 12 of TS 38.331.

[0180] In one embodiment, the switching interrupt duration (corresponding to the third processing duration in this disclosure) is T. interrupt , which is the interruption time of the switching process as specified in clause 6.1.1.

[0181] In one embodiment, the processing time for TA (corresponding to the fourth processing time in this disclosure) includes the time from the completion of the handover interruption duration statistics to the receipt of a valid TA command and the application of TA.

[0182] For example, the duration from the end of the switching interruption to the receipt of a valid TA command can be the duration from time Y until the receipt of a valid TA command; where Y = slot n + (T RRC_Process +T interrupt) / NR slot length; slot n is the last slot in which a PDSCH transmission carrying an RRC message was received, T RRC_Process The NR slot length is the duration of the NR time slot used to process received RRC messages. The TA command is used for the target primary cell.

[0183] For example, the received TA is applied to the uplink transmission delay of the target PCell and is greater than or equal to slot k+1, where k is defined in clause 4.2 of TS 38.213.

[0184] In one embodiment, when the terminal receives a direct SCell activation command [1X, TS38.331] from a secondary cell ending in time slot n, the terminal applies the corresponding action in [11, TS38.321] according to the minimum requirements defined in [10, TS 38.133], except in the following cases:

[0185] In one embodiment, the action of the sCellDeactivationTimer associated with the secondary cell [11,TS 38.321] is as defined in [10,TS 38.133] when the UE adds an SCell or when RCResumes, in slot n+(T RRC_Process Application of +T1) / NR slot length.

[0186] In one embodiment, the action of the sCellDeactivationTimer associated with the secondary cell [11,TS 38.321] is as defined in [10,TS 38.133] when the UE adds an SCell or when RCResumes, in slot n+(T RRC_Process Application of +T1+Tx) / NR slot length;

[0187] In one embodiment, the action of the sCellDeactivationTimer associated with the secondary cell [11,TS 38.321] is as defined in [10,TS 38.133] during handover in slot n+(T RRC_Process Application of +T2+T3) / NR slotlength.

[0188] In one embodiment, in addition to the first processing time, second processing time, third processing time and fourth processing time mentioned above, other delay values ​​agreed upon in the protocol may be added, such as a fifth processing time.

[0189] For example, in the following embodiment, Tx is added as the fifth processing duration.

[0190] In one embodiment, the action of the sCellDeactivationTimer associated with the secondary cell [11,TS 38.321] is as defined in [10,TS 38.133] during handover in slot n+(T RRC_Process +T2+T3+Tx) / NR slotlength directly activates the SCell.

[0191] In one embodiment, a second offset value may be appended to the first offset value, which is at least related to the duration of processing the RRC message.

[0192] For example, in the following embodiment, t milliseconds (e.g., 1ms) is appended as a second additional offset value.

[0193] In one embodiment, the action of the sCellDeactivationTimer associated with the secondary cell [11,TS 38.321] is as follows during handover: the UE, according to the definition in [10,TS 38.133], performs the action in slot n+1+(T RRC_Process +T2+T3+Tx) / NR slotlength directly activates the SCell.

[0194] In addition, under the Scell ​​direct activation mode, the start time of the Scell ​​deactivation timer is based on the current time plus an offset value (the first offset value, corresponding to the time offset of this disclosure). The determination method of this offset value is at least related to the duration of processing RRC messages and needs to be based on terminal capabilities and / or network capabilities.

[0195] In one embodiment, this operation can only be performed by a terminal that has the capability to start or restart the Scell ​​deactivation timer according to the direct Scell ​​activation method. Terminals that do not have this capability can determine when to start or restart the Scell ​​deactivation timer based on their own implementation.

[0196] In one embodiment, the terminal can only start or restart the Scell ​​deactivation timer in this manner if the network has issued the capability to start or restart the Scell ​​deactivation timer according to the direct Scell ​​activation method. When the terminal enters a cell that does not support this function, the timing of starting or restarting the Scell ​​deactivation timer can be determined based on its own implementation.

[0197] In one embodiment, this operation can only be performed if both of the following conditions are met simultaneously: the network has issued the capability to start or restart the Scell ​​deactivation timer according to the Scell ​​direct activation method, and the terminal has the capability to start or restart the Scell ​​inactivation timer according to the Scell ​​direct activation method. Otherwise, when the terminal starts or restarts the Scell ​​inactivation timer can be determined based on its own implementation.

[0198] It should be noted that, in some scenarios, the Scell ​​deactivation timer may also be referred to as the Scell ​​inactive timer in this disclosure.

[0213] The third processing time is the interrupt switching time; and

[0214] The fourth processing duration is the duration of the processing time advance (TA). The processing TA duration includes the duration from the end of the switching interrupt duration to the receipt of a valid TA command, and the application TA duration.

[0215] In one embodiment, the determining module 61 is further configured such that the processing time also includes a fifth processing duration determined based on a predetermined communication protocol.

[0216] In one embodiment, the determining module 61 is further configured such that the processing time is a time determined based on a time slot.
