DETAILED DESCRIPTION

The present disclosure provides a communication method, a terminal and a storage medium.

In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

Before a first moment, the terminal does not expect to receive first information, the first moment is after a second moment, the second moment is the moment of receiving the second information, the first information and the second information are used to indicate activation/deactivation of DTX/DRX on multiple carriers of the terminal, and the first information is different from the second information.

In the above embodiment, a method is provided to restrict the behavior of the terminal and the network during the period when the terminal activates/deactivates DTX/DRX on multiple carriers of the terminal, thereby ensuring that no other information is received during the period when the terminal activates/deactivates DTX/DRX on multiple carriers of the terminal, ensuring the stability of the terminal in executing activation/deactivation of DTX/DRX on multiple carriers of the terminal, and further ensuring the reliability of communication.

In combination with some embodiments of the first aspect, in some embodiments, the difference between the first moment and the second moment is a first duration.

In the above embodiment, by setting the first time duration, it is stipulated that the terminal and the network device shall not transmit other information for indicating activation/deactivation of DTX/DRX on multiple carriers of the terminal during this time duration, thereby ensuring the stability of the terminal's execution of activation/deactivation of DTX/DRX on multiple carriers of the terminal, and further ensuring the reliability of communication.

In combination with some embodiments of the first aspect, in some embodiments, the first moment is the latest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers of the terminal indicated by the second information.

In the above embodiment, since the effective time of activating/deactivating DTX/DRX on multiple carriers may be different, the latest effective time is taken as the time when the terminal does not receive another activation/deactivation information containing different indication content, thereby ensuring that the terminal has sufficient time to activate/deactivate the stability of DTX/DRX on multiple carriers of the terminal, thereby ensuring the reliability of communication.

In combination with some embodiments of the first aspect, in some embodiments, the first moment is a time at which activation/deactivation of DTX/DRX on the carrier where the second information is located takes effect;

or,

The first moment is the earliest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers of the terminal indicated by the second information.

In the above embodiment, the moment when the second information is located on the carrier or the earliest effective moment is taken as the first moment to ensure the accuracy of the determined first moment, thereby ensuring that the terminal can activate/deactivate DTX/DRX on multiple carriers of the terminal and ensure communication reliability.

In combination with some embodiments of the first aspect, the method further includes:

After the first moment, third information is received, where the third information is used to indicate activation/deactivation of DTX/DRX on multiple carriers of the terminal.

In the above embodiment, the effective time of the second information is later than the receiving time of the third information, so it is stipulated that the second information and the third information have the same indication on the second type carrier, thereby ensuring that the terminal can correctly execute the information and ensure communication reliability.

In combination with some embodiments of the first aspect, in some embodiments, the equivalent reception moment of the third information for the second type carrier is the Nth time domain unit corresponding to the Mth time domain unit after the effective moment of the second information on the second type carrier, the Nth time domain unit is located on the carrier sending the second information, the Mth time domain unit is located on the second type carrier, the Nth time domain unit is the first time domain unit overlapping with the Mth time domain unit, the second type carrier is a carrier whose effective moment of the second information on the second type carrier is later than or equal to the reception moment of the third information, and N and M are both positive integers.

or,

The first moment is the earliest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers of the terminal indicated by the second information.

In combination with some embodiments of the first aspect, in some embodiments, the method further includes:

In some embodiments, the present disclosure proposes discontinuous transmission or discontinuous reception of a network device.

DTX and DRX may affect the reception and transmission of signals by the terminal. For example, during DTX, some signals periodically sent by network devices will no longer be sent, and during DRX, some signals periodically sent by terminals will no longer be received by network devices. For cells configured with the DTX function, the state in which the network device normally sends downlink information can be recorded as DTX-on (correspondingly, the terminal also needs to monitor possible downlink signals), otherwise, the state in which the network device abnormally sends downlink signals can be recorded as DTX-off. For cells configured with the DRX function, the state in which the network device normally receives uplink signals can be recorded as DRX-on (correspondingly, the terminal can also send uplink signals that need to be sent), otherwise, the state in which the network device abnormally receives uplink signals can be recorded as DRX-off.

Optionally, the network device configures a periodic DRX on-off pattern (on-off mode) or a DTX on-off pattern for one or more carriers of the terminal through configuration signaling. The periodic DTX on-off pattern includes parameters such as a time domain period, a time domain offset, an on duration or an off duration. The periodic DRX on-off pattern includes parameters such as a time domain period, a time domain offset, an on duration or an off duration.

Taking DTX as an example, see Figure 1B, the starting position of the DTX cycle is the starting position of the on duration. See Figure 1C, the starting position of the DTX cycle is the starting position of the off duration.

In some embodiments, if the terminal has multiple service carriers, the multiple carriers can be configured with cell DTX/DRX configurations separately. After the base station configures cell DTX/DRX for one or more carriers of the terminal, the base station uses multicast DCI to activate cell DTX/DRX. Only after being activated, the cell DTX/DRX mechanism on the carrier starts to run.

In some embodiments, the terminal has four service carriers, namely carrier 1, carrier 2, carrier 3, and carrier 4. The SCS of the activated BWP of the terminal working on different carriers may be different, for example, SCS = 30kHz on carrier 1, carrier 2 = 15khz, carrier 3 = 60khz, and carrier 4 = 30khz.

In some embodiments, for a carrier configured with cell DTX/DRX, the base station may also use a multicast DCI in a specific format to activate or deactivate the cell DTX/DRX configuration of the carrier. For CA scenarios, the multicast DCI is sent on only one carrier, and the DCI carries multiple bits to indicate whether multiple service carriers configured with cell DTX/DRX are activated or deactivated. After receiving the DCI on one of its service carriers, the terminal determines the activation and deactivation time of the cell DTX/DRX on each carrier.

Optionally, for a certain serving cell, the terminal expects to apply a cell DTX or DRX activation/deactivation change at the beginning of timeslot X, where the SCS of timeslot X corresponds to the activated DL or UL BWP of the serving cell, respectively.

Slot X is the first slot that starts no earlier than (i.e., the same as or after) slot n+D, where D is the delay and n is the slot of the PDCCH of DCI format 2_X containing the SCS based on the PDCCH.

For example, referring to Figure 1D, there are four service carriers, namely carrier 1, carrier 2, carrier 3, and carrier 4. The terminal receives DCI in slot 1 of carrier 1.

Step S2103: The network device sends the second information.

In some embodiments, the terminal receives the second information. Alternatively, it can also be understood that the terminal receives the second information sent by the network device.

In some embodiments, the network device sends the second information to the terminal.

In some embodiments, the second information is used to indicate activation/deactivation of DTX/DRX on multiple carriers of the terminal. Optionally, the second information is used to indicate activation of DTX/DRX on multiple carriers. For example, the second information is used to indicate activation of DTX on multiple carriers. For example, the second information is used to indicate activation of DRX on multiple carriers. Optionally, the second information is used to indicate deactivation of DTX/DRX on multiple carriers. Optionally, for example, the second information is used to indicate deactivation of DTX on multiple carriers. For example, the second information is used to indicate deactivation of DRX on multiple carriers.

In some embodiments, the name of the second information is not limited. For example, it is indication information, control information, etc. In some embodiments, the second information is DCI, RRC, MAC CE or other information, which is not limited in the embodiments of the present disclosure.

Step S2104: The terminal activates/deactivates DTX/DRX based on the second information.

In the embodiment of the present disclosure, after receiving the second information, the terminal can determine to activate/deactivate each carrier according to the second information. DTX/DRX.

Step S2105: Before the first moment, the terminal does not expect to receive the first information.

In some embodiments, the first time is after the second time, and the second time is the time when the second information is received. In some embodiments, during the time period between the time when the terminal receives the second information and the first time, the first information is not expected to be received.

In some embodiments, the terminal not expecting to receive the first information may also be understood as the terminal not wanting to receive the first information, the terminal not receiving the first information, the terminal not communicating with the network device, etc.

In some embodiments, the first information is used to indicate activation/deactivation of DTX/DRX on multiple carriers of the terminal.

In some embodiments, the first information is different from the second information. Optionally, the first information is different from the second information in that the operations indicated by the first information and the second information are different. Alternatively, it can also be understood that the operations of executing activation/deactivation of DTX/DRX indicated by the first information and the second information are different.

In the embodiment of the present disclosure, after receiving the second information, the terminal does not expect to receive the first information during the time period between receiving the second information and the first moment. Alternatively, it can also be understood that the terminal does not expect to receive other information different from the second information. Alternatively, it can also be understood that the terminal does not expect to receive other information for activating/deactivating DTX/DRX.

In some embodiments, the difference between the first moment and the second moment is a first duration. Optionally, the first duration is agreed upon by a communication protocol, or the first duration is configured by a terminal, or the first duration is configured by a network device, which is not limited in the embodiments of the present disclosure. In the embodiments of the present disclosure, the length of the time period between the moment when the terminal receives the second information and the first moment is the first duration. Alternatively, it can also be understood that, with the moment when the terminal receives the second information as the starting point, the terminal does not expect to receive the first information within the first duration. Alternatively, it can also be understood that, with the moment when the terminal receives the second information as the starting point, the moment after the first duration is the first moment. Optionally, the moment when the terminal receives the second information can also be referred to as the end moment of the channel carrying the second information.

In some embodiments, the first moment is the latest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers of the terminal indicated by the second information. In some embodiments, the terminal has multiple carriers, and the effective moments of activation/deactivation of DTX/DRX by the second information in multiple carriers may be the same or different, so it is necessary to determine the first moment according to the effective moments in different carriers, so the latest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers is determined as the first moment. For example, referring to FIG. 1D , the effective moment on carrier 2 is the latest, so the effective moment on carrier 2 is determined as the first moment.

In some embodiments, the first moment is the effective moment of activation/deactivation of DTX/DRX on the carrier where the second information is located. Alternatively, the first moment is the earliest effective moment among the effective moments of activation/deactivation of DTX/DRX on multiple carriers of the terminal indicated by the second information.

Optionally, the first moment is the effective moment of activation/deactivation of DTX/DRX on the carrier where the second information is located. In the embodiment of the present disclosure, when the terminal receives the second information, one carrier among multiple carriers can be received, so the effective moment of activation/deactivation of DTX/DRX of the second information on the carrier is taken as the first moment. For example, referring to FIG. 1D, DCI is received on carrier 1, so the effective moment slot 7 of carrier 1 is taken as the first moment.

It should be noted that the terminal receives the second information through one carrier among multiple carriers, and the effective time of activation/deactivation of cell DTX/DRX of the terminal on the carrier is not later than the effective time on other carriers. Therefore, the effective time on the carrier can be understood as the earliest effective time of the second information on multiple carriers.

Optionally, the terminal has multiple carriers, and the effective time of activating/deactivating DTX/DRX in the multiple carriers by the second information may be the same or different, so it is necessary to determine the first time according to the effective time in different carriers, so the earliest effective time among the effective times of activating/deactivating DTX/DRX on multiple carriers is determined as the first time. For example, referring to FIG1D, the effective time on carrier 1, carrier 3, and carrier 4 are all the earliest, so the effective time on carrier 1, carrier 3, or carrier 4 is determined as the first time.

In some embodiments, the network device will further send third information after the first moment, that is, the terminal will further receive the third information after the first moment. The third information is used to indicate activation/deactivation of DTX/DRX on multiple carriers of the terminal.

For the third information, the effective time of the second information on the carrier may be later than or equal to the receiving time of the third information on the corresponding carrier, or the effective time of the second information on the carrier may be earlier than the receiving time of the third information on the corresponding carrier. Different situations are explained below.

In some embodiments, DTX/DRX is activated/deactivated according to the indication of the third information on the first type of carrier, and the first type of carrier is a carrier where the effective time of the second information on the first type of carrier is earlier than the reception time of the third information.

In the embodiment of the present disclosure, the time when the second information is effective on the first type of carrier is earlier than the time when the third information is received, and the operation of activating/deactivating DTX/DRX is performed on the first type of carrier according to the instruction of the third information on the first type of carrier. For example, referring to FIG. 1D, the terminal receives the third information in slot 7 of carrier 1, and the second information has been effective in slot 7 of carrier 1, slot 14 of carrier 3, and slot 7 of carrier 4. Therefore, for carrier 1, carrier 3, and carrier 4, DTX/DRX is activated/deactivated according to the instruction of the third information.

In some embodiments, the indication of the third information on the second type of carrier is ignored, and the second type of carrier is a carrier where the effective time of the second information on the second type of carrier is later than or equal to the receiving time of the third information.

In the embodiment of the present disclosure, the effective time of the second information on the second type of carrier is later than or equal to the receiving time of the third information, indicating that the second information has not been executed, and the indication of the second information on the first type of carrier needs to be considered, so the indication of the third information on the second type of carrier is ignored. For example, referring to FIG1D, the terminal receives the third information in slot 7 of carrier 1, and the second information is effective in slot 4 of carrier 2, which is later than slot 7 of carrier 1. Therefore, for carrier 2, the third information is ignored, and DTX/DRX is activated/deactivated according to the indication of the second information.

In some embodiments, the indication of the third information on the second type carrier is the same as the indication of the second information on the second type carrier, and the second type carrier is a carrier where the effective time of the second information on the second type carrier is later than or equal to the reception time of the third information.

In the embodiment of the present disclosure, the effective time of the second information on the second type of carrier is later than or equal to the receiving time of the third information, indicating that the second information has not been executed yet, and the indication of the second information on the first type of carrier needs to be considered, so the indication of the third information on the second type of carrier is set to the same indication as the second information, so it will not affect the terminal to perform the corresponding activation/deactivation of DTX/DRX. For example, referring to Figure 1D, the terminal receives the third information in slot 7 of carrier 1, and the second information is effective in slot 4 of carrier 2, which is later than slot 7 of carrier 1. Therefore, for carrier 2, the indication of the third information on the second type of carrier is the same as the indication of the second information on the second type of carrier.

In some embodiments, the equivalent reception moment of the third information for the second type carrier is the Nth time domain unit corresponding to the Mth time domain unit after the effective moment of the second information on the second type carrier, the Nth time domain unit is located on the carrier sending the second information, the Mth time domain unit is located on the second type carrier, the Nth time domain unit is the first time domain unit overlapping with the Mth time domain unit, the second type carrier is a carrier where the effective moment of the second information on the second type carrier is later than or equal to the reception moment of the third information, and N and M are both positive integers.

Optionally, the time domain unit is a time slot, a symbol, etc., which is not limited in the embodiments of the present disclosure. The equivalent reception time of the third information is the time after the actual reception time of the third information. It can also be understood that when the terminal calculates the effective time of the third information for the second type of carrier, the equivalent reception time of the third information is used to calculate the effective time. The equivalent reception time is after the effective time of the second information of the second type of carrier. Alternatively, it can also be understood that after receiving the third information, the terminal stores the third information and considers that the reception time of the third information on the second type of carrier is the Nth time domain unit corresponding to the Mth time domain unit after the effective time of the second information on the second type of carrier.

Step S2106: Before the first moment, the network device does not send the first information.

In the embodiment of the present disclosure, the network device does not send the first information before the first moment, so the terminal may not receive the first information before the first moment.
