For the RRC connection state, a power saving Signal, i.e., a wake Signal (WUS), or power saving downlink control information (Downlink Control Information for powersaving, DCP) is introduced in the power saving project of 3GPP standard Release 16 (Release 16, R16). WUS is a low power consumption detection signal. If the UE detects WUS signal, it means that it needs to monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH), but if WUS is not detected, it ignores the monitoring of (skip) PDCCH.

In the power saving project of 3GPP standard Release 17 (Release 17, R17), for the idle state discontinuous reception (Discontinuous Reception, DRX) scenario, a power saving signal is proposed: paging early indication (Paging Early Indication, PEI). The PEI is typically configured before Paging Occasion (PO), and if the UE does not detect the power saving signal (i.e., PEI), the Paging downlink control information (Paging DCI) needs to be ignored (skip), otherwise, the Paging DCI needs to be monitored. In R17, a PDCCH ignore (skip) mechanism is introduced for RRC connection state, i.e. PDCCH skip informs the user to skip listening for a period of time or switch the search space group in DCI.

In the power saving mechanism of R16 or R17, it is seen that, in any power saving signal, a Modem (Modem) of the terminal is required to detect the power saving signal.

As shown in fig. 1b, a separate transceiver may be introduced: a Low Power Wake-Up Receiver (Low Power Wake-Up Receiver) receives the Power saving signal, and a Modem (Modem) part or a Main Radio (Main Radio) part of the terminal can be woken Up only after the Low Power Wake-Up Receiver is woken Up by a Low Power Wake-Up signal (Low Power Wake Up Signal, LP-WUS), otherwise the Modem part will be in a deep sleep or off state all the time.

This may be achieved by using a wake-up signal to trigger the main radio and a separate receiver with the ability to monitor the wake-up signal with ultra low power consumption. The primary radio is used for data transmission and reception. Unless the primary radio is turned on, the primary radio may be turned off or set to deep sleep.

In the RRC connected state, the primary radio (or primary transceiver) of the terminal is not allowed to go deep sleep, i.e. radio resource management (Radio Resource Management, RRM) measurements and/or channel state information (Channel State Information, CSI) measurements are performed normally. Therefore, how to reduce the power consumption of the terminal in the RRC connected state is a problem to be solved.

The embodiment of the disclosure shows an interaction schematic diagram of an information transmission method. As shown in fig. 2a, an embodiment of the present disclosure relates to an information transmission method for a communication system 100, the method comprising:

step S2101: the network device transmits the first information.

In some embodiments, the network device sends the first information to the terminal. The first information indicates that the terminal activates a first power consumption state in an RRC connected state.

In some embodiments, the first power consumption state comprises a low power consumption state of the terminal in an RRC connected state.

In some embodiments, the first power consumption state includes the first transceiver of the terminal being in a low power consumption state, wherein the low power consumption state is different from the deep sleep or off state. The first transceiver is in a low power state at least one of: RRM measurement; CSI measurement.

In some embodiments, in a first power consumption state, the first transceiver of the terminal is in a low power consumption state and the second transceiver of the terminal listens to the LP-WUS. The second transceiver wakes up the first transceiver upon receiving the LP-WUS.

In some embodiments, the second transceiver may be a low power wake-up receiver for receiving the LP-WUS. The first transceiver may be a primary wireless transceiver of the terminal for air interface communication.

In some embodiments, the first transceiver may be referred to as a Main Radio (MR), and the first receiver may be referred to as a low power receiver (Low Power Receiver, LR).

In some embodiments, the first transceiver includes a transmit (Tx) module and/or a receive (Rx) module that operate on NR signals/channels. The first transceiver may also receive a low power wake-up related signal/channel (e.g., LP-WUS).

A specific example is provided below in connection with any of the embodiments described above:

1. and protecting the behavior of the terminal in the low power consumption state or activated state of the connection state terminal.

a) The low power state, i.e. the terminal is activated or the terminal activates a second transceiver, i.e. a low power wake-up receiver, for receiving a low power wake-up signal (Low Power Wake Up Signal, LP-WUS) for waking up a main radio receiver (or called main transceiver) for data listening.

b) The low power state, i.e., the first transceiver (main receiver) portion of the terminal is functional off (e.g., stops listening to the PDCCH) or in a dormant state.

2. The terminal being activated for low power listening may issue a display indication (first information) to activate low power listening based on the network, the terminal switching from the current BWP to the target BWP according to the display indication, and performing primary transceiver sleep on the target BWP.

a) As an example: and the terminal receives a display instruction for activating low-power consumption monitoring by the network, and switches from the current BWP to the target BWP.

Wherein, the display indication may carry BWP switching information, wherein the BWP switching information includes target BWP information.

Wherein the display indication includes only the sleep indication and the target BWP information is preconfigured for the network or agreed upon according to the protocol.

As an embodiment, the target BWP may be an initial BWP or a default (default) BWP.

As an example, the target BWP may be a dormant BWP.

b) As an example: the terminal receives a display instruction of activating low-power consumption monitoring by the network, and if the current BWP is the initial BWP or default BWP, the terminal maintains the current BWP terminal; otherwise the terminal switches from the current BWP to the initial BWP or default BWP.

c) As an example: the terminal receives a display instruction of activating low-power consumption monitoring issued by the network, and if the current BWP is the dormant BWP, the terminal maintains the current BWP terminal; otherwise the terminal switches from the current BWP to the target BWP.

d) As an example: the terminal being activated for low power consumption listening may be based on the network issuing a display indication to activate low power consumption listening,

the terminal may switch from the current BWP to the target BWP according to the display indication, for a plurality of carrier aggregated secondary cell groups, i.e., at least one secondary cell (scell) in one cell group performs the BWP switch operation above BWP switch: switch from current BWP to target BWP. The secondary cell group aggregated by multiple carriers can be provided in a display instruction for activating low-power consumption monitoring by the network, or can be preconfigured by the network or agreed according to a protocol.

e) A preferred embodiment: i.e. the secondary cell, will perform the BWP handover operation above on all carriers for the primary cell.

3. The terminal being activated for low power consumption listening may switch from the current BWP to the target BWP upon satisfaction of the predetermined configuration condition based on whether the network issues a pre-configuration condition for activating low power consumption listening to be satisfied, and perform primary transceiver dormancy on the target BWP.

a) As an example: the terminal activated low power listening may be based on the following pre-configured conditions: the low power consumption state in which the terminal is activated may also be that a preset configuration condition is satisfied. Such as: no data is transmitted for the timer period T1 while detecting that the low power synchronization signal (Low Power Synchronization Signal, LP-SS) is above a predetermined threshold, etc.

b) As an example: if the current BWP is the initial BWP or default BWP, the terminal maintains the current BWP terminal; otherwise the terminal switches from the current BWP to the initial BWP or default BWP.

c) As an example: the terminal activated low power consumption listening may switch from the current BWP to the target BWP when the predetermined configuration condition is satisfied based on whether the pre-configuration condition for network downlink activation low power consumption listening is satisfied, and perform primary transceiver dormancy on the target BWP, and may perform the above switching operation for multiple carrier aggregated secondary cell groups, i.e., performing BWP switching on at least one secondary cell (scell) in one cell group: switch from current BWP to target BWP.

d) A preferred embodiment: i.e. for the primary cell, the secondary cell, the BWP on all carriers is subjected to the fallback operation.

4. If the network configuration issues a pre-configuration condition (first configuration condition) for activating low-power consumption monitoring, wherein when no data transmission is configured in the terminal timer duration T1, the duration T1 is not less than the BWP inactivity timer (BWP InactivityTimer, BWP IAT timer). If so set, after the BWP IAT time timeout occurs, the BWP of the existing mechanism falls back first, and then sleeps on the falling BWP.

a) As an example: the duration of T1 is not less than the BWP IAT timer of any one serving cell (serving cell) configured for the terminal. If so set, after the BWP IAT time timeout occurs, the BWP of the existing mechanism falls back first, and then sleeps on the falling BWP.

The following are some embodiments (i.e. the terminal performs BWP handover first, i.e. switches to target BWP and then sleeps on target BWP):

1> if BWP is activated and active DL BWP for the serving cell is not dormant BWP, and the serving cell is not PSCell of deactivated SCG, and LP-WUS listening is activated.

2> if the serving cell is running, it is regarded as expiration of the BWP inactivity timer (bwplnactigytimer) of the serving cell.

2> does not monitor PDCCH on target BWP.

2> does not monitor the PDCCH for the target BWP.

2> does not receive DL-SCH on the target BWP.

2> does not transmit SRS on the target BWP.

2> is not transmitted on the UL-SCH on the target BWP.
