[0184] In step 2101, the terminal determines the change of the working state of the terminal when entering and / or leaving the first working mode.

[0185] Optionally, the power consumption of the terminal in the first working mode can be less than a third value, that is, the first working mode can be understood as a low-power working mode. Optionally, the terminal can enter or leave the first working mode based on the configuration or indication of the network device, or the terminal can enter or leave the first working mode based on its own implementation, or the terminal can enter or leave the first working mode based on the protocol predefinition. In some embodiments, when the terminal is in the first working mode, the network device can schedule the terminal to perform uplink transmission and / or downlink transmission in the first working mode.

[0186] Optionally, the terminal can perform any one or any multiple of the uplink transmission, the downlink transmission, and the SL transmission in the first working mode. The following is an example of which type of transmission the terminal performs in the first working mode:

[0187] For example, in some embodiments, the terminal can perform a first transmission with a first device and a second transmission with a second device. The first transmission can include the terminal sending a first signal to the first device, and the second transmission can include the terminal receiving a second signal sent by the second device. Optionally, the first device can be a device other than the terminal, and the second device can also be a device other than the terminal. The first device and the second device may, for example, be other terminals or network devices, and the first device and the second device can be the same or different.

[0188] In some embodiments, when the first device and the second device are the same, the first transmission and the second transmission can respectively include uplink transmission and downlink transmission, or respectively include downlink transmission and uplink transmission, or both are SL transmission.

[0189] In some embodiments, the terminal can perform uplink transmission in the first operation mode, without performing downlink transmission, SL transmission, i.e., the downlink transmission, SL transmission is performed in the normal power consumption mode. Alternatively, in some other embodiments, the terminal can perform SL transmission in the first operation mode, while the downlink transmission, uplink transmission is performed in the normal power consumption mode. Alternatively, in some other embodiments, the terminal can perform downlink transmission in the first operation mode, while the SL transmission, uplink transmission is performed in the normal power consumption mode. Alternatively, in some other embodiments, the terminal can perform uplink transmission and SL transmission in the first operation mode, while the downlink transmission is performed in the normal power consumption mode. Alternatively, in some other embodiments, the terminal can perform downlink transmission and SL transmission in the first operation mode, while the uplink transmission is performed in the normal power consumption mode; alternatively, in some other embodiments, the terminal can perform uplink transmission and downlink transmission in the first operation mode, while the SL transmission is performed in the normal power consumption mode; alternatively, in some other embodiments, the terminal can perform uplink transmission, downlink transmission, SL transmission in the first operation mode.

[0190] In some embodiments, the first device is different from the second device, the first transmission can include uplink transmission and / or SL transmission with the first device, and the second transmission can include downlink transmission and / or SL transmission with the second device. At this time, the terminal can perform uplink transmission and / or SL transmission with the first device in the first operation mode, while the downlink transmission and / or SL transmission with the second device is performed in the normal power consumption mode. Alternatively, the terminal can perform downlink transmission and / or SL transmission with the second device in the first operation mode, while the uplink transmission and / or SL transmission with the first device is performed in the normal power consumption mode; alternatively, the terminal can perform uplink transmission, SL transmission with the first device, downlink transmission, SL transmission with the second device in the first operation mode.

[0191] It should be noted that the above is only some examples, and other possible transmission modes are also applicable to the embodiments of the present disclosure, which are not limited specifically.

[0192] Optionally, in some embodiments, when the terminal is in the first operation mode, the terminal and the network device can perform transmission through a first channel. The first channel can include at least one of the following:

[0193] Low power physical downlink control channel (LP PDCCH);

[0201] Low power physical sidelink control channel (LP PSCCH);

[0202] Low power physical sidelink shared channel (LP PSSCH);

[0203] Low power physical sidelink feedback channel (LP PSFCH).

[0204] Optionally, the above-mentioned channels are only examples and do not limit the first channel. The first channel can also refer to a transmission channel that can appear in a future communication system of the terminal. All channels through which the terminal communicates with other devices are applicable to the first channel of the present disclosure and can implement the low-power working mode provided by the present disclosure. The present disclosure does not make specific limitations in this regard.

[0205] Optionally, the working state can refer to an RRC state of the terminal, and can also refer to other working states of the terminal, such as a working state that can occur in a future communication system of the terminal, and the disclosure does not make a specific limitation thereon.

[0206] Optionally, when the working state is an RRC state of the terminal, the RRC state can include, but is not limited to, at least one of the following: an RRC connected state (RRC_CONNECTED), an RRC inactive state (RRC_INACTIVE), and an RRC idle state (RRC_IDLE).

[0207] Optionally, the terminal can determine the change of the working state of the terminal when entering the first working mode and / or leaving the first working mode based on a protocol agreement and / or based on an indication of the network device.

[0208] Optionally, in some embodiments, the terminal can determine any one of the following (a1)-(a3) based on a protocol agreement and / or based on the first signaling sent by the network device:

[0209] (a1) the working state of the terminal after entering the first working mode is the same as the working state of the terminal before entering the first working mode;

[0210] For example, the working state of the terminal before entering the first working mode is RRC_INACTIVE, and it can be determined that the terminal is in RRC_INACTIVE after entering the first working mode.

[0211] For example, the working state of the terminal before entering the first working mode is RRC_CONNECTED, and it can be determined that the terminal is in RRC_CONNECTED after entering the first working mode.

[0212] For example, the working state of the terminal before entering the first working mode is RRC_IDLE, and it can be determined that the terminal is in RRC_IDLE after entering the first working mode.

[0213] (a2) the terminal needs to switch the working state of the terminal to a first state before entering the first working mode, and the working state of the terminal after entering the first working mode is the first state;

[0214] For example, assuming that the first state is RRC_INACTIVE, and the terminal is currently in RRC_IDLE, the terminal first switches the working state from RRC_IDLE to RRC_INACTIVE, then enters the first working mode, and keeps the working state as RRC_INACTIVE in the first working mode.

[0215] For example, assuming that the first state is RRC_IDLE and the terminal is currently in RRC_CONNECTED, the terminal first switches the working state from RRC_CONNECTED to RRC_IDLE, then enters the first working mode, and keeps the working state as RRC_IDLE in the first working mode.

[0216] For example, assuming that the first state is RRC_IDLE and the terminal is currently in RRC_CONNECTED, the terminal first switches the working state from RRC_CONNECTED to RRC_IDLE, then enters the first working mode, and keeps the working state as RRC_IDLE in the first working mode.

[0217] (a3) After the terminal enters the first working mode, the terminal switches the working state to the first state.

[0218] Optionally, regardless of the working state of the terminal before the terminal enters the first working mode, as long as the terminal enters the first working mode, the working state of the terminal is switched to the fixed first state.

[0219] For example, assuming that the first state is RRC_IDLE, regardless of the working state of the terminal before the terminal enters the first working mode, as long as the terminal enters the first working mode, the working state of the terminal is switched to RRC_IDLE.

[0220] For example, assuming that the first state is RRC_CONNECTED, regardless of the working state of the terminal before the terminal enters the first working mode, as long as the terminal enters the first working mode, the working state of the terminal is switched to RRC_CONNECTED.

[0221] For example, assuming that the first state is RRC_INACTIVE, regardless of the working state of the terminal before the terminal enters the first working mode, as long as the terminal enters the first working mode, the working state of the terminal is switched to RRC_INACTIVE.

[0222] Optionally, in some embodiments, the terminal can determine any one of the following (b1)-(b2) based on a protocol agreement and / or based on the first signaling sent by the network device:

[0223] (b1) The related configuration parameters of the working state after the terminal enters the first working mode are the same as the related configuration parameters of the working state before the terminal enters the first working mode;

[0224] For example, the related configuration parameters of the working state before the terminal enters the first working mode include configuration A, and the terminal multiplexes the related configuration parameters of the working state before entering the first working mode after entering the first working mode, that is, configuration A.

[0225] For example, the working state of the terminal before entering the first working mode is RRC_CONNECTED, and the related configuration parameters of the working state before entering the first working mode include configuration A, and it can be determined that the terminal is in RRC_CONNECTED after entering the first working mode, and the related configuration parameters of the working state after entering the first working mode include configuration A.

[0226] For example, the terminal first switches the working state from RRC_INACTIVE to RRC_CONNECTED, the related configuration parameters of RRC_CONNECTED include configuration A, then enters the first working mode, and keeps the working state as RRC_CONNECTED in the first working mode; and it is determined that the related configuration parameters of the working state after entering the first working mode include configuration A.

[0227] (b2) The related configuration parameters of the working state after the terminal enters the first working mode are the same as the related configuration parameters of the last first state of the terminal.

[0228] For example, the related configuration parameters of the last first state of the terminal include configuration B, the terminal enters the first state after entering the first working mode, and the related configuration parameters of the last first state are used, that is, configuration B.

[0229] For example, the working state of the terminal before entering the first working mode is RRC_CONNECTED, and the related configuration parameters of the last RRC_CONNECTED include configuration B, and it can be determined that the terminal is in RRC_CONNECTED after entering the first working mode, and the related configuration parameters of the working state after entering the first working mode include configuration B.

[0230] For example, the terminal first switches the working state from RRC_INACTIVE to RRC_CONNECTED, the related configuration parameters of RRC_CONNECTED include configuration B, then enters the first working mode, and keeps the working state as RRC_CONNECTED in the first working mode; and it is determined that the related configuration parameters of the working state after entering the first working mode include the related configuration parameters of the last RRC_CONNECTED of the terminal, that is, configuration B.

[0231] For example, no matter what the working state of the terminal is before entering the first working mode, as long as the terminal enters the first working mode, the working state of the terminal is switched to RRC_CONNECTED, and it is assumed that the relevant configuration parameters of the terminal when it was last in RRC_CONNECTED include configuration B, it is determined that the relevant configuration parameters of the working state of the terminal after entering the first working mode include the relevant configuration parameters of the terminal when it was last in RRC_CONNECTED, i.e., configuration B.

[0232] Optionally, in some embodiments, the terminal can determine any one of the following (c1)-(c3) based on a protocol agreement and / or based on the second signaling sent by the network device.

[0233] (c1) the working state of the terminal after leaving the first working mode is the same as the working state of the terminal before leaving the first working mode;

[0234] For example, if the working state of the terminal before leaving the first working mode is RRC_INACTIVE, it can be determined that the terminal is in RRC_INACTIVE after leaving the first working mode.

[0235] For example, if the working state of the terminal before leaving the first working mode is RRC_CONNECTED, it can be determined that the terminal is in RRC_CONNECTED after leaving the first working mode.

[0236] For example, if the working state of the terminal before leaving the first working mode is RRC_IDLE, it can be determined that the terminal is in RRC_IDLE after leaving the first working mode.

[0237] (c2) the terminal needs to switch the working state of the terminal to a first state before leaving the first working mode, and the working state of the terminal after leaving the first working mode is the first state.

[0238] For example, it is assumed that the first state is RRC_INACTIVE, and the terminal is currently in RRC_IDLE, the terminal first switches the working state from RRC_IDLE to RRC_INACTIVE, then leaves the first working mode, and keeps the working state as RRC_INACTIVE after leaving the first working mode.

[0239] For example, it is assumed that the first state is RRC_CONNECTED, and the terminal is currently in RRC_INACTIVE, the terminal first switches the working state from RRC_INACTIVE to RRC_CONNECTED, then leaves the first working mode, and keeps the working state as RRC_CONNECTED after leaving the first working mode.

[0240] For example, assuming the first state is RRC_IDLE, and the terminal is currently in RRC_CONNECTED, the terminal first switches the working state from RRC_CONNECTED to RRC_IDLE, then leaves the first working mode, and keeps the working state as RRC_IDLE after leaving the first working mode.

[0241] (c3) After the terminal leaves the first working mode, the terminal switches the working state to the first state.

[0242] Optionally, regardless of the working state of the terminal before leaving the first working mode, as long as the terminal leaves the first working mode, the terminal switches the working state to a fixed first state.

[0243] For example, assuming the first state is RRC_IDLE, regardless of the working state of the terminal before leaving the first working mode, as long as the terminal leaves the first working mode, the terminal switches the working state to RRC_IDLE.

[0244] For example, assuming the first state is RRC_CONNECTED, regardless of the working state of the terminal before leaving the first working mode, as long as the terminal leaves the first working mode, the terminal switches the working state to RRC_CONNECTED.

[0245] For example, assuming the first state is RRC_INACTIVE, regardless of the working state of the terminal before leaving the first working mode, as long as the terminal leaves the first working mode, the terminal switches the working state to RRC_INACTIVE.

[0246] Optionally, in some embodiments, the terminal can determine any one of the following (d1)-(d2) based on a protocol agreement and / or based on the second signaling sent by the network device:

[0247] (d1) The related configuration parameters of the working state after the terminal leaves the first working mode are the same as the related configuration parameters of the working state before the terminal leaves the first working mode.

[0248] For example, the related configuration parameters of the working state before the terminal leaves the first working mode include configuration C, and the terminal multiplexes the related configuration parameters of the working state before leaving the first working mode, i.e., configuration C.

[0249] For example, the working state before the terminal leaves the first working mode is RRC_CONNECTED, and the related configuration parameters of the working state before the terminal leaves the first working mode include configuration C. It can be determined that the terminal is in RRC_CONNECTED after leaving the first working mode, and the related configuration parameters of the working state after the terminal leaves the first working mode include configuration C.

[0250] For example, the terminal first switches the working state from RRC_INACTIVE to RRC_CONNECTED, the related configuration parameters of RRC_CONNECTED include configuration C, then leaves the first working mode, and keeps the working state as RRC_CONNECTED after leaving the first working mode; and determines that the related configuration parameters of the working state of the terminal after leaving the first working mode include configuration C.

[0251] (d2) The related configuration parameters of the working state of the terminal after leaving the first working mode are the same as the related configuration parameters of the last first state of the terminal.

[0252] For example, the related configuration parameters of the last first state of the terminal include configuration D, the terminal is in the first state after leaving the first working mode, and the related configuration parameters of the last first state are used, i.e. configuration D.

[0253] For example, the working state of the terminal before leaving the first working mode is RRC_CONNECTED, the related configuration parameters of the last RRC_CONNECTED include configuration D, and it can be determined that the terminal is in RRC_CONNECTED after leaving the first working mode, and the related configuration parameters of the working state of the terminal after leaving the first working mode include configuration D.

[0254] For example, the terminal first switches the working state from RRC_INACTIVE to RRC_CONNECTED, the related configuration parameters of RRC_CONNECTED include configuration D, then leaves the first working mode, and keeps the working state as RRC_CONNECTED after leaving the first working mode; and determines that the related configuration parameters of the working state of the terminal after leaving the first working mode include the related configuration parameters of the last RRC_CONNECTED of the terminal, i.e. configuration D.

[0255] For example, no matter what working state the terminal is in before leaving the first working mode, as long as the terminal leaves the first working mode, the working state of the terminal is switched to RRC_CONNECTED, and assuming that the related configuration parameters of the terminal when it was last in RRC_CONNECTED include configuration D, it is determined that the related configuration parameters of the working state of the terminal after leaving the first working mode include the related configuration parameters of the last RRC_CONNECTED of the terminal, i.e. configuration D.

[0256] Optionally, the first signaling and the second signaling described above can include at least one of the following: downlink control information (DCI) signaling, medium access control control element (MAC CE) signaling, radio resource control (RRC) signaling, and the like.

[0257] The following will be specifically illustrated and introduced as follows: the change of the working state of the terminal when the terminal determines to enter the first working mode and / or to leave the first working mode:

[0258] In some embodiments, the terminal can determine at least one of the following based on a protocol agreement or based on an indication of the network device:

[0259] The working state of the terminal after entering the first working mode is the same as the working state before entering the first working mode;

[0260] The related configuration parameters of the working state of the terminal after entering the first working mode are the same as the related configuration parameters of the working state before entering the first working mode.

[0261] For example, when the terminal is in RRC_CONNECTED before entering the first working mode, the terminal will continue to work based on RRC_CONNECTED after entering the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_CONNECTED before entering the first working mode after entering the first working mode.

[0262] For example, when the terminal is in RRC_INACTIVE before entering the first working mode, the terminal will continue to work based on RRC_INACTIVE after entering the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_INACTIVE before entering the first working mode after entering the first working mode.

[0263] For example, when the terminal is in RRC_IDLE before entering the first working mode, the terminal will continue to work based on RRC_IDLE after entering the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_IDLE before entering the first working mode after entering the first working mode.

[0264] Optionally, in other embodiments, the terminal can determine at least one of the following based on a protocol agreement or based on an indication of the network device:

[0265] When the terminal enters the first working mode, the working state of the terminal needs to be switched to the first state before entering the first working mode.

[0266] The working state of the terminal after entering the first working mode is a first state.

[0267] The related configuration parameters of the working state of the terminal after entering the first working mode are the same as the related configuration parameters of the working state of the terminal before entering the first working mode.

[0268] For example, the first state can be RRC_INACTIVE. Before entering the first working mode, the terminal needs to be switched to RRC_INACTIVE, and then the terminal enters the first working mode and continues to work based on RRC_INACTIVE. Alternatively, the terminal can reuse the related configuration parameters of RRC_INACTIVE before entering the first working mode.

[0269] Alternatively, in some other embodiments, the terminal can determine at least one of the following based on a protocol agreement:

[0270] The terminal switches the working state to the first state after entering the first working mode.

[0271] The related configuration parameters of the working state of the terminal after entering the first working mode are the same as the related configuration parameters of the first state of the terminal in the last time.

[0272] For example, the first state can be RRC_INACTIVE. After entering the first working mode, the terminal needs to be switched to RRC_INACTIVE for working. Alternatively, the terminal can reuse the related configuration parameters of RRC_INACTIVE in the last time when the terminal is in RRC_INACTIVE.

[0273] Alternatively, in some other embodiments, the terminal can receive first signaling sent by the network device, and the first signaling can be used to configure at least one of the following:

[0274] The terminal switches the working state to the first state after entering the first working mode.

[0275] The related configuration parameters of the working state of the terminal after entering the first working mode are the same as the related configuration parameters of the first state of the terminal in the last time.

[0276] Alternatively, in some other embodiments, the terminal can determine at least one of the following based on a protocol agreement:

[0277] The working state of the terminal after leaving the first working mode is the same as the working state of the terminal before leaving the first working mode.

[0278] The related configuration parameters of the working state of the terminal after the terminal leaves the first working mode are the same as the related configuration parameters of the working state of the terminal before the terminal leaves the first working mode.

[0279] For example, when the terminal is in RRC_CONNECTED before leaving the first working mode, the terminal will continue to work based on RRC_CONNECTED after leaving the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_CONNECTED before leaving the first working mode after leaving the first working mode.

[0280] For another example, when the terminal is in RRC_INACTIVE before leaving the first working mode, the terminal will continue to work based on RRC_INACTIVE after leaving the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_INACTIVE before leaving the first working mode after leaving the first working mode.

[0281] For another example, when the terminal is in RRC_IDLE before leaving the first working mode, the terminal will continue to work based on RRC_IDLE after leaving the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_IDLE before leaving the first working mode after leaving the first working mode.

[0282] Optionally, in some other embodiments, the terminal can determine at least one of the following based on a protocol agreement:

[0283] When the terminal leaves the first working mode, the terminal needs to be switched to the first state first and then leave the first working mode.

[0284] The working state of the terminal after leaving the first working mode is the first state.

[0285] The related configuration parameters of the working state of the terminal after the terminal leaves the first working mode are the same as the related configuration parameters of the working state of the terminal before the terminal leaves the first working mode.

[0286] For example, the first state can be RRC_INACTIVE, and the terminal needs to be switched to RRC_INACTIVE before leaving the first working mode, and then the terminal is controlled to leave the first working mode, and the terminal will continue to work based on RRC_INACTIVE after leaving the first working mode. Optionally, the terminal can reuse the related configuration parameters of RRC_INACTIVE before leaving the first working mode after leaving the first working mode.

[0287] Optionally, in some other embodiments, the terminal can determine at least one of the following based on a protocol agreement:

[0288] The terminal switches the working state of the terminal to the first state after the terminal leaves the first working mode.

[0289] The related configuration parameters of the working state of the terminal after the terminal leaves the first working mode are the same as the related configuration parameters of the first state of the terminal last time.

[0290] In an example, the first state can be RRC_INACTIVE, and after the terminal leaves the first working mode, the terminal needs to be switched to RRC_INACTIVE for working. Optionally, after the terminal leaves the first working mode, the related configuration parameters of the terminal when the terminal is in RRC_INACTIVE last time can be reused.

[0291] Optionally, in another embodiment, the terminal can receive second signaling sent by the network device, and the second signaling is used to configure at least one of the following:

[0292] The terminal switches the working state of the terminal to the first state after the terminal leaves the first working mode.

[0293] The related configuration parameters of the working state of the terminal after the terminal leaves the first working mode are the same as the related configuration parameters of the first state of the terminal last time.
