[0045] Embodiments of the present disclosure provide a terminal state switching method and apparatus, a communication device, a communication system, and a storage medium.

[0046] In a first aspect, an embodiment of the present disclosure provides a terminal state switching method, which includes:

[0047] The terminal switches the state of a transceiver, wherein the transceiver of the terminal includes: a first transceiver and a second transceiver;

[0048] The power consumption of the first transceiver in an operating state is higher than the power consumption of the second transceiver in an operating state.

[0049] In the above embodiment, the terminal has a first transceiver and a second transceiver, and the states of the transceivers of the terminal are different. This can meet the communication needs of the terminal in different communication states while achieving energy saving of the terminal.

[0050] In conjunction with some embodiments of the first aspect, the terminal switching the state of the transceiver includes:

[0051] According to the first information of the network device, the terminal switches the first transceiver to a working state;

[0052] or,

[0053] If the first condition is met, the terminal switches the first transceiver to a working state.

[0054] In the above embodiment, the terminal can switch the first transceiver to the working state according to the first information sent by the network device, or the terminal can switch the first transceiver to the working state according to the first condition determined by itself, thereby meeting the transceiver state switching of different switching requirements.

[0055] In conjunction with some embodiments of the first aspect, the method includes:

[0056] According to a first signal received by a second transceiver in a working state, wherein the first signal carries first information.

[0057] In the above embodiment, the first signal received by the first transceiver carries the first information. Thus, the terminal can receive the first information while keeping the high-power-consuming first transceiver in a dormant or turned-off state, thereby further reducing the power consumption of the terminal.

[0058] In conjunction with some embodiments of the first aspect, the first information includes at least one of the following:

[0059] A first indication, used to indicate that the first transceiver enters a working state;

[0060] BWP flag, used to indicate the activated BWP of the terminal;

[0061] The first time information is used to indicate the starting time when the first transceiver enters the working state;

[0062] Activation information of tracking reference signal TRS configuration, used to activate TRS configuration;

[0063] Random access parameters.

[0064] Based on the above scheme, the first information carries at least one of the above contents. In this way, the terminal can receive one or more types of information when the first transceiver is in a sleep or turned off state, thereby maintaining low power consumption of the terminal.

[0065] In combination with some embodiments of the first aspect,

[0066] The first indication is specifically used to indicate at least one of the following:

[0067] The first transceiver monitors a physical downlink control channel (PDCCH);

[0068] The first transceiver exits the sleep state;

[0069] Starting the first transceiver;

[0070] The transceiver used by the terminal is switched from the second transceiver to the first transceiver;

[0071] The terminal sends data;

[0072] The terminal performs activation of the BandWidth Part (BWP) switching;

[0073] The uplink (UL) of the terminal is out of synchronization.

[0074] In the above embodiment, the first information can explicitly or implicitly indicate whether the first transceiver needs to switch to the working state, thereby meeting the indication requirements in different communication scenarios, and implicitly indicating that the terminal needs to use the first transceiver to perform transceiver operations will not only trigger the terminal to wake up the first transceiver (that is, make the first transceiver enter the working state), but also indicate the tasks that the first transceiver needs to perform, saving the bit overhead of the first information.

[0075] In conjunction with some embodiments of the first aspect, the first indication specifically indicates that an activated BWP of the terminal is switched from the first BWP to the second BWP, or that the activated BWP of the terminal is switched from the second BWP back to the first BWP;

[0076] The first BWP includes: a BWP pre-specified by the network device.

[0077] In the above embodiment, if the current terminal uses BWP to communicate with the network device, then after the first transceiver of the terminal enters the working state, which BWP to use can also be indicated by the first indication. In this way, on the one hand, the first indication wakes up the first transceiver of the terminal, and at the same time clarifies the BWP used after the first transceiver of the terminal is awakened, thereby further reducing the signaling overhead.

[0078] In combination with some embodiments of the first aspect, the network device pre-specifies a BWP including: a dormant BWP.

[0079] Based on the above scheme, the sleep BWP is dedicated to the BWP of the terminal sleep. Therefore, by instructing the terminal's activated BWP to switch to the sleep BWP, it can implicitly indicate (or indirectly indicate) that the first transceiver is sleep. At the same time, the BWP used by the terminal and the indication that the first transceiver enters a non-working state are realized, saving signaling overhead.

[0080] In combination with some embodiments of the first aspect, the first information specifically indicates an activated BWP switching of at least one secondary cell of the terminal.

[0081] Based on the above solution, if the terminal has the capability of carrier aggregation, the first information may indicate activation of BWP switching of one or more secondary cells of the terminal. In this way, the state related to the terminal and the transceiver may also be switched.

[0082] In combination with some embodiments of the first aspect, the method further includes:

[0083] The first transceiver enters a working state and determines an activated BWP of the terminal.

[0084] Based on the above solution, after the first transceiver enters the working state, the activated BWP of the terminal will be further determined, so that the terminal can communicate with the base station based on the BWP instead of using the system bandwidth of the cell to communicate, thereby reducing the power consumption of the terminal.

[0085] In combination with some embodiments of the first aspect, activating the BWP of the terminal includes at least one of the following:

[0086] Activate the first activated downlink DL BWP configured by the network device for the terminal;

[0087] Activate the first activated uplink UP BWP configured by the network device for the terminal;

[0088] Activate the previous activated DL BWP;

[0089] Activate the previous activated UL BWP;

[0090] activating a DL BWP configured by the network device for the first transceiver;

[0091] The UL BWP configured by the network device for the first transceiver is activated.

[0092] Based on the above scheme, this method can determine the activation BWP used by the first transceiver to enter the working state by the terminal itself or based on a method known to both the network device and the terminal without network notification, thereby saving the signaling overhead of the terminal.

[0093] In combination with some embodiments of the first aspect, the method further includes:

[0094] According to the protocol agreement or network configuration, the starting time for the first transceiver to enter the working state is determined.

[0095] Based on the above scheme, the terminal can determine the starting time when the first transceiver enters the working state according to the protocol agreement, so that there is no need for special notification from the network device, which can save signaling. The terminal determines the starting time when the first transceiver enters the working state according to the network configuration, so that the network device can flexibly configure the starting time when the first transceiver of the terminal enters the working state according to the communication state and / or communication demand.

[0096] In conjunction with some embodiments of the first door, the terminal satisfies the first condition including at least one of the following:

[0097] The terminal has uplink data to send;

[0098] The terminal needs to perform radio resource management RRM measurements;

[0099] The measuring period of the measuring interval is reached;

[0100] The terminal is configured to send an uplink reference signal;

[0101] The terminal is to perform downlink DL synchronization.

[0102] Based on the above solution, when the terminal detects any one of the conditions corresponding to the above first condition, the terminal automatically puts the first transceiver into working state, thereby eliminating the need for notification from the network device and saving unnecessary signaling overhead.

[0103] In combination with some embodiments of the first aspect, the uplink reference signal includes: a sounding reference signal SRS.

[0104] Based on the above solution, it is specifically limited that the uplink reference signal can include at least SRS, that is, when the terminal needs to perform uplink positioning, the first transceiver will enter the working state to implement the uplink positioning.

[0105] In combination with some embodiments of the first aspect, the method further includes:

[0106] The DL of the terminal is out of synchronization, and the first transceiver performs DL synchronization according to the tracking reference signal TRS.

[0107] Based on the above solution, if the DL of the terminal is synchronized, the first transceiver will perform DL synchronization according to the TRS, so that the first transceiver can be awakened in time to maintain DL synchronization between the terminal and the network device.

[0108] In combination with some embodiments of the first aspect, the activation information carried by the first signal is further used to indicate a sending time interval between the first signal and the TRS.

[0109] Based on the above scheme, since the first signal carries activation information and also indicates the sending time interval between the first signal and TRS, when the terminal needs to wake up the first transceiver to perform TRS measurement to achieve DL synchronization, the terminal can determine when the terminal wakes up the first transceiver based on the sending time interval and control the first transceiver to perform TRS measurement.

[0110] In combination with some embodiments of the first aspect, the method further includes:

[0111] Determine the TRS configuration according to the protocol agreement or the radio resource control RRC message.

[0112] Based on the above solution, another method is provided for the terminal to monitor TRS at a specific time-frequency resource position when performing DL synchronization, which has implementation characteristics, so that the corresponding method can be flexibly selected according to needs.

[0113] In combination with some embodiments of the first aspect, the method further includes:

[0114] The terminal loses UL synchronization, and the first transceiver initiates a random access for recovering UL synchronization according to the random access parameters.

[0115] Based on the above scheme, if the terminal loses UL synchronization, it will perform random access for UL synchronization according to the random access parameters included in the first information. In this way, the network device will know that the purpose of the random access performed by the current terminal is to complete UL synchronization, and there is no need to perform resource scheduling and other operations for the terminal.

[0116] In conjunction with some embodiments of the first aspect, the random access parameter includes at least one of the following:

[0117] A first index indicating a random access preamble;

[0118] The second index indicates a random access occasion RO.

[0119] Based on the above solution, the random access parameters include the random access preamble and / or RO. When the random access of the terminal is for UL synchronization, the RO and / or random access preamble can be selected for convenience of the network device to know.

[0120] In combination with some embodiments of the first aspect, the terminal switches the state of the transceiver, including:

[0121] According to the second information of the network device, the terminal switches the first transceiver to a non-working state;

[0122] or,

[0123] If the second condition is met, the terminal switches the first transceiver to a non-working state.

[0124] Based on the above solution, the terminal can switch the first transceiver to a non-working state according to the second information of the network device or when the second condition is met, thereby saving power consumption of the terminal.

[0125] In combination with some embodiments of the first aspect, the second information indicates at least one of the following:

[0126] The first transceiver enters a dormant state;

[0127] The transceiver used by the terminal is switched from the first transceiver to the second transceiver;

[0128] The first transceiver stops monitoring the PDCCH;

[0129] The second transceiver starts monitoring the first signal;

[0130] The first transceiver stops working;

[0131] The first transceiver is turned off;

[0132] The terminal stops sending data;

[0133] The active BWP of the terminal switches to the dedicated BWP of the first signal;

[0134] Activate the dedicated BWP for the first signal;

[0135] The second time information indicates a starting time when the first transceiver of the terminal enters a non-working state.

[0136] Based on the above scheme, the second information can cause the first transceiver to enter a sleep state through the indication of any one of the above information. In this way, on the one hand, signaling overhead is saved, and on the other hand, the high-power consumption first transceiver of the terminal is turned off, thereby saving power consumption of the terminal.

[0137] In combination with some embodiments of the first aspect, the method further includes:

[0138] Determine a starting time when a first transceiver of the terminal enters a non-working state.

[0139] Based on the above scheme, the terminal does not immediately enter the non-working state of the first transceiver upon receiving the second information or satisfying the second condition, but can additionally determine the starting time when the first transceiver enters the non-working state, thereby meeting different communication needs.

[0140] In conjunction with some embodiments of the first aspect, determining a starting time when the first transceiver of the terminal enters a non-working state includes at least one of the following:

[0141] Determine, according to the transmission time of the feedback of the transmission block TB corresponding to the second information, the starting time at which the first transceiver enters the non-working state;

[0142] The starting time when the first transceiver enters the non-working state is determined according to the receiving time of the second information and the number n of intervals of the time units.

[0143] Based on the above solution, the starting time when the first transceiver of the terminal enters the non-working state can adopt any of the above methods, so as to achieve synchronization between the terminal and the network device in recognizing that the first transceiver of the terminal enters the non-working state.

[0146] The terminal has completed the transmission of data to be sent;

[0147] The terminal has no data to send.

[0148] Based on the above scheme, when the timer times out, data transmission is completed or there is no data to be sent, the first transceiver enters a non-working state, so that the terminal has lower power consumption, thereby saving power consumption of the terminal to extend the standby time.

[0149] In combination with some embodiments of the first aspect, the method further includes at least one of the following:

[0150] The terminal receives the media access control MAC service data unit SDU and starts the timer;

[0151] The terminal sends a MAC SDU and starts the timer.

[0152] Based on the above scheme, the time to start the timer is limited, so that the terminal starts the timer after receiving the SDU or starts the timing after sending the MAC SDU, that is, the timer is started after completing data transmission.

[0153] In combination with some embodiments of the first aspect, the method further includes:

[0154] At least one set of configuration information for a first signal is received, wherein the first signal is monitored by a second transceiver.

[0155] Based on the above solution, the terminal can receive one or more sets of configurations for receiving the first signal, so that it is convenient for the subsequent second transceiver to monitor the first signal.

[0159] In combination with some embodiments of the first aspect, the method further includes:

[0160] The configuration information is activated or deactivated according to the third information of the network device.

[0161] When the terminal is configured with multiple sets of configuration information, it can select to use the activated configuration information to monitor the first signal according to the third information.

[0162] In combination with some embodiments of the first aspect, the first signal also carries fourth information, wherein the fourth information indicates carrying fifth information; the fifth information indicates whether the second transceiver needs to monitor the second signal, wherein the result of the second signal is used to determine whether the terminal needs to monitor the paging opportunity PO.

[0163] Based on the above solution, the first signal may also carry information indicating whether the terminal needs to monitor the second signal. In this way, the terminal can reduce unnecessary monitoring of the second signal, thereby further saving power consumption of the terminal.

[0351] S2202: The network device sends third information.

[0352] In some embodiments, the third information is used to activate or deactivate configuration information of the first signal.

[0353] In some embodiments, the third information is used for configuration information required for activating the second transceiver to monitor the first signal.

[0354] In some embodiments, the third information is used to deactivate configuration information that the second transceiver is no longer used for monitoring the first signal.

[0355] In some embodiments, when the network device sends multiple sets of configuration information to the terminal, the network device sends the third information to activate or deactivate the configuration information of the first signal.

[0356] In some embodiments, the network device sends the third information, and the terminal receives the third information.

[0357] S2203: The network device sends second information.

[0358] In some embodiments, the second information is used to instruct the first transceiver of the terminal to switch to a non-working state.

[0359] In some embodiments, the first transceiver being in a non-working state may be understood as at least one of the following:

[0360] The first transceiver is in a dormant state.

[0361] The first transceiver is in a non-operating state.

[0362] The first transceiver is in an off state.

[0363] The first transceiver is not activated.

[0364] In some embodiments, the second transceiver is in an active state when the first transceiver is in an inactive state.

[0365] In some embodiments, the second transceiver is in an active state when the first transceiver is in an inactive state.

[0366] In some embodiments, the second transceiver is in a working state and can monitor various power saving signals, such as a wake-up signal (WUS), a paging early indicator (PEI), or a low power-synchronizing signal (LP-SS).

[0367] In some embodiments, the network device sends the second information, and the terminal receives the second information.

[0368] In some embodiments, the second transceiver listens to the first signal.

[0369] In some embodiments, the first signal carries first information.

[0370] In some embodiments, the second transceiver is used to monitor the first signal when the first transceiver is in an operating state or a non-operating state, and the first signal may carry the first information.

[0371] In some embodiments, the second information indicates but is not limited to at least one of the following:

[0372] The first transceiver enters a dormant state;

[0373] The transceiver used by the terminal is switched from the first transceiver to the second transceiver;

[0374] The first transceiver stops monitoring the PDCCH;

[0375] The second transceiver starts monitoring the first signal;

[0376] The first transceiver stops working;

[0377] The first transceiver is turned off;

[0378] The terminal stops sending data;

[0379] The active BWP of the terminal switches to the dedicated BWP of the first signal;

[0380] Activate the dedicated BWP for the first signal;

[0381] The second time information indicates a starting time when the first transceiver of the terminal enters a non-working state.

[0382] In some embodiments, when the first transceiver enters the sleep state, it means that the first transceiver temporarily stops the transceiver function.

[0383] In some embodiments, the second information may also instruct the first transceiver to enter a shutdown state or a deactivated state.

[0384] In some embodiments, the second information indicates that a receiver mainly used by the terminal has been switched from the first transceiver to the second transceiver.

[0385] In some embodiments, if the terminal needs to monitor various downlink channels such as PDCCH instead of receiving physical layer signals, it may be necessary to start the first transceiver to achieve this. Therefore, the terminal can be indirectly instructed to enter a situation where the first transceiver is in a non-working state by instructing the terminal to suspend downlink channel monitoring. Exemplarily, the second information can instruct the first transceiver or the terminal to stop PDCCH monitoring, and instruct the terminal to put the first transceiver in a non-working state.

[0386] In some embodiments, the second information indicates starting or continuing monitoring of the first signal, which may emphasize monitoring of the first signal, thus being equivalent to sleeping, shutting down or deactivating the first transceiver.

[0387] In some embodiments, the second information directly instructs the first transceiver to stop working, or the first transceiver is turned off.

[0388] In some embodiments, the second information instructs the terminal to stop sending and receiving data.

[0389] In some embodiments, the data may include, but is not limited to, business data.

[0390] If the terminal stops sending or receiving service data, the high-power-consuming first transceiver of the terminal may be turned off.

[0391] In some embodiments, the terminal may be configured with a dedicated BWP for monitoring the first signal. In this case, the second information may indicate that the active BWP of the terminal is switched to the dedicated BWP, thereby indirectly indicating that the terminal enters a situation where the first transceiver is in a non-working state.

[0392] In some embodiments, the dedicated BWP may be a BWP configured with the first signal.

[0393] Of course, in some cases, the BWP configured with the first signal is not a dedicated BWP.

[0394] In some embodiments, the second information indicates the BWP that activates the first signal, indicating that the activated BWP of the terminal is the BWP that can be monitored by the second transceiver for the first signal, which is equivalent to indirectly instructing the terminal to put the first transceiver into a non-working state.

[0395] In some embodiments, the second information includes second time information.

[0396] The second time information can be used by the terminal to determine the starting time when the first transceiver is in a non-working state. The second time information may include the time information of the starting time when the first transceiver is in a non-working state, or the time offset. The time offset can be used to obtain the time information of the starting time when the first transceiver is in a non-working state after deviating from the time offset in the time domain according to the receiving time or the reference time of the second information.

[0397] S2204: The terminal determines a starting time when the first transceiver enters a non-working state.

[0398] In some embodiments, the terminal determines, based on the second time information, the starting time at which the first transceiver of the terminal enters the non-working state.

[0399] In some embodiments, the terminal determines the starting time when the first transceiver enters the non-working state according to the transmission time of the feedback of the transmission block TB corresponding to the second information.

If the network device only sends one set of configuration information, there is no need to send the third information, that is, step S4102 may be omitted. For another example, the network device may send the first signal or not according to communication requirements.

[0619] Some embodiments may include steps S4101 and S4105. If the network device only sends one set of configuration information, there is no need to send the third information, that is, step S4102 can be omitted. For another example, the network device may send the first signal, or may not send the first signal according to communication requirements. When the network device does not send the first signal, step S4104 may be omitted. However, the network device may send a second signal that can be received by the second transceiver of the terminal.

[0620] As shown in FIG4B , this functional embodiment provides a terminal state switching method, which is executed by a network device. The terminal switching method may include:

[0621] S4201: The network device sends at least one set of configuration information of a first signal.

[0622] In some embodiments, the network device may include at least an access network device.

[0623] In some embodiments, the configuration information is used for monitoring of the first signal by the second transceiver.

[0624] In some embodiments, the network device broadcasts, multicasts, or unicasts at least one set of configuration information of the first signal.

[0625] In some embodiments, the network device sends multiple sets of configuration information of the first signal.

[0626] S4202: The network device sends third information.

[0627] In some embodiments, the third information is used to activate or deactivate configuration information of the first signal.

[0628] In some embodiments, the third information is used for configuration information required for activating the second transceiver to monitor the first signal.

[0629] In some embodiments, the third information is used to deactivate configuration information indicating that the second transceiver is no longer used for monitoring the first signal.

[0630] In some embodiments, when the network device sends multiple sets of configuration information to the terminal, the network device sends the third information to activate or deactivate the configuration information of the first signal.

[0631] S4203: The network device sends a first signal.

[0632] In some embodiments, the steps related to the first signal can refer to the related descriptions of the corresponding embodiments of Figures 2A to 2D.

[0633] In some embodiments, the first signal carries fourth information.

[0634] In some embodiments, the fourth information is used to determine whether the terminal needs to monitor the second signal.

[0635] In some embodiments, the second signal may be a power saving signal different from the first signal.

[0636] In some embodiments, the second signal may be an advance indication. Exemplarily, the advance indication may include but is not limited to a paging advance indication.

[0637] In some embodiments, the second signal may include, but is not limited to, downlink control information scrambled by an energy-saving radio network temporary identifier (DCI with CRC scrambled by PS-RNTI, DCP).

[0638] In some embodiments, the monitoring result of the second transceiver on the second signal may be used to indicate whether the terminal needs to monitor a paging occasion (PO).

[0639] S4204: The network device sends a second signal.

[0640] In some embodiments, the second signal may include, but is not limited to: DCP and / or PEI, etc.

[0641] For example, the relevant description of the second signal may refer to the relevant description of the embodiments corresponding to FIG. 2A and FIG. 2B .

[0642] It is worth noting that: some embodiments may include step S4203, and the remaining steps may be omitted. For example, if the protocol stipulates the configuration information of the first signal, the network device may not send the configuration information of the first signal, so S4101 to S4102 can be omitted. In some cases, the network device may not configure the second signal, or the fourth information carried by the first signal indicates that the terminal does not need to monitor the second signal, then the network device may not send the second signal, and S4204 may be omitted.

[0643] Some embodiments may include steps S4203 and S4204, and the remaining steps may be omitted. For example, if the protocol stipulates the configuration information of the first signal, the network device may not send the configuration information of the first signal, so S4101 to S4102 may be omitted.

[0644] Some embodiments may include steps S4201, S4203, and S4204, and the remaining steps may be omitted. For example, if the network device configures a set of configuration information of the first signal for the terminal, there is no need for the third information to indicate the activated configuration information. For another example, the terminal and the network device may select the activated configuration information from multiple sets of configuration information according to pre-configured conditions or protocol agreements, and in this case, there is no need for the network device to send the third information.

[0645] Some embodiments may include step S4204, and the remaining steps may be omitted. For example, the terminal puts the first transceiver of the terminal into a non-working state according to the second condition being met, and the network device may also determine that the second condition is met according to the agreed condition, and the network device may send the first signal or may not send the first signal, but may send the second signal.

[0646] The disclosed embodiments provide a method for switching between MR and LR used by a terminal, based on display or implicit indication, or based on a timer, or based on an event trigger, to achieve UE energy saving while taking latency into consideration.

[0647] Several methods of switching the transceiver used by the terminal to MR are provided below.

[0648] Solution 1: The network device explicitly instructs the terminal to use MR. The explicit instruction may be the aforementioned first information. Exemplarily, the explicit instruction may come from LP-WUS.

[0649] The LP-WUS carries an indication message (the indication message may be the aforementioned first message) and / or an activated BWP ID.

[0650] The indication information is specifically used to indicate at least one of the following:

[0651] Activate MR;

[0652] MR starts monitoring PDCCH;

[0653] MR leaves the sleep state;

[0654] Instruct MR to perform BWP switching, etc.

[0655] The BWP ID is used to instruct the MR to start monitoring from the BWP on the MR side. After the terminal receives the instruction from the LP-WUS, k time slots (slots) or subframes (subframes) or milliseconds (ms) or symbols (symbols), the instruction is considered to be effective. That is, the MR starts to monitor the PDCCH or data transmission, or data reception.

[0656] The value of k may be based on network-side configuration, LP-WUS indication, or protocol agreement.

[0657] If the LP-WUS does not carry the activated BWP ID information, the terminal can activate the BWP in the following manner.

[0658] (1) Activate the first active DL BWP and / or the first active UL BWP configured by the network side;

[0659] (2) Activate the latest activated DL BWP and / or UL BWP used last time.

[0660] (3) Activate the DL BWP and / or UL BWP configured by the network side for MR activation.

[0661] As an embodiment: the LP-WUS carries an indication information instructing the MR to perform BWP switching, switching from the first BWP to the second BWP or switching from the third BWP back to the fourth BWP.

[0662] For example, if the bit value of the indication bit is 1, the first BWP is switched to the second BWP or maintained at the currently activated BWP; wherein the first BWP may be the currently activated BWP (may be a dormant BWP) or a BWP pre-designated by the network; wherein the second BWP may be a BWP pre-designated by the network;

[0663] If the bit value of the indication bit is 0, the third BWP is switched to the fourth BWP; wherein the third BWP may be a currently activated BWP or a BWP pre-designated by the network; wherein the fourth BWP may be a BWP pre-designated by the network (such as a dormant BWP);

[0664] As an embodiment: LP-WUS carries an indication information instructing MR to perform BWP switching, which can be performed for a secondary cell group aggregated with multiple carriers, that is, at least one secondary cell (scell) in a cell group performs the above switching operation of BWP switching: switching from the first BWP to the second BWP or switching from the third BWP back to the fourth BWP.

[0665] Scenario 2:

[0666] When the following conditions are met, the UE activates the MR: After the MR is activated, the MR starts to monitor the PDCCH or data transmission or data reception.

[0667] The following conditions may include at least one of the following:

[0668] (1) Uplink data arrives;

[0669] (2) Perform RRM measurements;

[0670] (3) During the measurement period of the measurement gap;

[0671] (4) Sending a pre-configured periodic SRS;

[0672] (5) Periodic measurements to achieve DL synchronization.

[0673] Solution 3: If the terminal loses synchronization in the uplink, the terminal can be awakened by LP-WUS to initiate a random access process to regain synchronization.

[0674] For example, the LP-WUS sends a random access preamble index (preamble index) and / or a random access opportunity index (RO index) for initiating a RACH process for uplink synchronization purposes.

[0675] When the terminal receives the command, it wakes up the MR to perform the RACH process.

[0676] Based on the above solutions 1, 2 and 3, if the MR wakes up and finds that the DL is out of sync, the LP-WUS can carry the third information indicating the activation of the TRS configuration. After the MR wakes up, according to the fast synchronization of TRS, at least one TRS configuration is pre-configured through RRC signaling. Optionally, the LP-WUS can also indicate the time interval between the LP-WUS and TRS transmission, etc.

[0677] Several methods of switching the transceiver used by the terminal to MR are provided below.

[0678] Solution 1: Switching the transceiver used by the terminal to LR based on a timer (timer-based MR to LR switching).

[0679] A timer is configured on the network side. The timer is used to control the MR to enter the sleep state or monitor the switch from the MR to the LR.

[0680] If the MAC receives a MAC SDU or sends a MAC SDU, the timer needs to be started or restarted. If the timer times out, the MR enters the sleep state, or monitors the MR to the LR, or stops monitoring the PDCCH on the MR, or starts monitoring the LR.

[0681] Exemplarily, if the MAC entity receives a MAC SDU of a dedicated traffic channel (DTCH) or a common control channel (CCCH) or a multicast service channel (MTCH), a timer is started or restarted. The timer may be (lr-Timer).

[0682] If any MAC entity sends a MAC SDU for DTCH or DCCH, the timer is started or restarted.

[0683] If the timer times out, the lower layer is notified of the timer timeout. Solution 2: Explicitly indicate the terminal to use LR, for example, linearly indicate the terminal to switch from MR to LR (explicit indication for MR to LR switching).

[0684] The network side sends a command to the terminal, and the command is used for at least one of the following:

[0685] MR enters sleep state;

[0686] Monitoring switches from MR to LR;

[0687] Stop monitoring the PDCCH on the MR;

[0688] Start monitoring LR.

[0689] In some embodiments, when the terminal receives the instruction, after the HARQ of the TB where the instruction is located is fed back, it is considered that the instruction is effective, that is, the MR enters the sleep state.

[0690] In some other embodiments, when the terminal receives the instruction, it switches monitoring from MR to LR, or stops monitoring the PDCCH on MR, or starts monitoring the LR.

[0691] After n time slots or subframes or milliseconds or symbols, the command is considered to be effective, that is, the MR enters the sleep state, or the monitoring is switched from the MR to the LR, or the monitoring of the PDCCH on the MR is stopped, or the monitoring of the LR is started.

[0692] The value of n can be based on the network configuration or specified in the protocol.

[0693] The instruction exists in the RRC dedicated signaling, or in the MAC CE, or in the PDCCH.

[0694] Solution 3: DL LP-WUS BWP based BWP switching for MR to LR switching.

[0695] The network side configures frequency domain resources for monitoring LP-WUS. The frequency domain resources are a BWP, which can be called LP-WUS BWP.

[0696] LP-WUS BWP is one of the dedicated BWPs.

[0697] The BWP configuration information includes indication information, and the indication information is used to indicate that the current BWP is a LP-WUS BWP.

[0698] Based on the BWP indicator in the DCI indicating the BWP ID of the LP-WUS BWP, the MR enters the sleep state, or monitors switching from the MR to the LR, or stops monitoring the PDCCH on the MR, or starts monitoring the LR.

[0699] The LP-WUS BWP is a special BWP, and the configuration indicates that the BWP is a LP-WUS BWP. Based on the indication in the DCI, the indication indicates that the LP-WUS BWP is activated, and the MR enters the sleep state, or monitors the switch from MR to LR, or stops monitoring the PDCCH on the MR, or starts monitoring the LR.

[0700] Solution 4: LP-WUS configuration and operation behavior can be as follows:

[0701] Before schemes 1, 2 and 3, the terminal obtains the configuration information about LP-WUS through RRC dedicated signaling, and the configuration information of LP-WUS includes at least one set of LP-WUS configuration. If multiple sets of LP-WUS configurations are included, one of the LP-WUS configurations is activated and used based on RRC or MAC CE or DCI or LP-WUS.

[0702] After the LP-WUS is activated, the LP-WUS is used to indicate whether there is indication information in the DCP closest to the LP-WUS.

[0703] Furthermore, the TA configuration is sent through the LP-WUS to maintain the uplink synchronization relationship between the UE and the MR.

[0704] The disclosed embodiments provide switching between MR and LR based on display or implicit indication, or based on timer, or based on event triggering, so as to switch between LR and MR to achieve UE energy saving while taking latency into consideration.

[0705] In short, the switching between LR and MR is performed based on explicit or implicit indication, or based on a timer, or based on an event trigger. The switching indication takes effect at an agreed time.

[0706] LP-WUS configuration and activation / deactivation.
