The word "example" is used only to convey the concept that the related concept is one of a possible, non-limiting variety of embodiments.

[0176] In order for those skilled in the art to better understand the embodiments of the present application, the following description is first made.

[0177] I. Low Power Wake-up Signal (LP-WUS) and Low Power Wake Up Receiver (LP-WUR)

[0178] The concept of Low Power Wake-up Signal (LP-WUS) and Low Power Wake Up Receiver (LP-WUR) is proposed in the related art. As shown in Figure 2 When there is data transmission, the terminal receives the LP-WUS signal through the LP-WUR to activate the main receiver (MR) to wake up from the ultra-deep sleep state to receive data; when there is no data transmission, the MR is turned off, which can greatly save the energy of the terminal.

[0179] (II) Connected-Discontinuous Reception (C-DRX) in connected state;

[0180] DRX is a function introduced by User Equipment (UE) for power saving, which is configured by Radio Resource Control (RRC) layer. In connected state, if the RRC layer configures the Medium Access Control (MAC) layer with DRX function, the UE can monitor PDCCH discontinuously in physical layer; otherwise, the UE must monitor PDCCH continuously. In RRC connected state, after the network configures C-DRX function:

[0181] (1) The UE listens to PDCCH channel according to the DRX cycle configured by the base station;

[0182] (2) In the On Duration time, the UE normally listens to the PDCCH channel, and after the On Duration, the UE can enter the DRX state, i.e. sleep state, to save energy.

[0183] (3) After the UE enters the sleep state, if there is downlink data arriving at the network, the base station cannot perform downlink PDCCH scheduling.

[0184] (III) DRX related timers;

[0185] (1) DRX on duration timer (drx-onDurationTimer): from the start of a DRX cycle, during the running of the timer, the UE needs to continuously listen to the PDCCH subframes of the network PDCCH.

[0186] (2) DRX inactivity timer (drx-InactivityTimer): the timer starts after the UE receives new data scheduling PDCCH signaling. This parameter indicates the number of consecutive PDCCH subframes that the UE needs to continue to monitor in the active state after successfully decoding a downlink PDCCH channel DCI.

[0187] (3) Downlink Hybrid Automatic Reboot Request Round Trip Time (HARQ RTT) timer: The length of this timer is the minimum time interval between the HARQ feedback moment and the receipt of the HARQ retransmission for the process. The terminal will only start the downlink process on the first symbol after the HARQ NACK feedback if the data corresponding to the downlink process has not been successfully decoded. The retransmission scheduling of the downlink process will only be scheduled after the timer's timeout value.

[0188] (4) DRX Downlink Retransmission Timer (drx-RetransmissionTimerDL): The slot length value of the bandwidth part (BWP) of the received transmission block.

[0189] (iv) LP-WUS;

[0190] The current LP-WUS supports On-Off Keying (OOK)-1 and OOK-4.

[0191] Where OOK-1: One OFDM symbol corresponds to a single bit, and the subcarrier (SC) of LP-WUS is:

[0192] OOK=1 means that all SCs are used for modulation;

[0193] OOK=0 means that all SCs have zero power (from the baseband perspective).

[0194] OOK-4: Time-domain transform M-bit OOK. The N SCs of OOK-4 are generated by a transform, which can be a Discrete Fourier Transform (DFT) or a least squares transform.

[0195] The signal processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0197] Step 101: Obtain an energy-saving signal, which is used to indicate whether the main receiver of the terminal stops listening to the physical downlink control channel (PDCCH).

The first low-power wake-up signal is used to indicate whether the main receiver starts listening to the PDCCH.

[0272] Optionally, the sixth period is configured according to at least one of the following: a period of C-DRX; a sixth dedicated period.

[0273] For example, the sixth period can be a period of C-DRX divided by X, X being a positive integer. The sixth dedicated period includes a plurality of preset values, such as 1 ms, 2 ms, etc.

[0281] The information indication field in the embodiments of the present application can be a newly added indication field, such as the sleep state indication field described above, and the newly added indication field and the length of the indication field are configured by the network side and / or determined by a predefined manner. The information indication field described above can also be an existing indication field in the PDCCH, for example, a modulation and coding information field, a new data indicator (NDI) information field, a redundancy version (RV) information field, a hybrid automatic repeat request (HARQ) process number information field, an antenna port, and a demodulation reference signal (DMRS) sequence initialization information field, and a carrier indication field (for scheduling PDCCH).

[0282] For example, for DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2, a 1-bit indication of the energy saving signal is added in the PDCCH monitoring adaptation indication field in the PDCCH monitoring adaptation indication field in the DCI.

[0283] A5: Bit length of the indication information field;

[0284] A6: High-level parameter carrying the energy saving signal.

[0286] The high-level parameter corresponds to the PDCCH monitoring adaptation indication field, and the PDCCH monitoring adaptation indication field is used to indicate one preset value in the high-level parameter.

[0288] In the embodiments of the present application, the power saving signal based on the downlink control information can be a dedicated DCI, a scheduling PDCCH, and / or a non-scheduling PDCCH.

[0294] The time when the terminal receives the scheduling data of the downlink control information and feeds back the confirmation message. For example, the seventh effective time is greater than 0, the terminal receives the scheduling data of the downlink control information, and feeds back the confirmation (ACK), and then the main receiver immediately enters the dormant state. If the scheduling data of the downlink control information is not successfully received or a negative confirmation (NACK) message is fed back, the main receiver does not enter the dormant state and continues to listen to the PDCCH.

[0307] The signal processing method of the present application is described in detail below in conjunction with embodiments.

[0308] Embodiment one:

[0309] The low-power receiver receives a low-power wake-up signal according to a first period according to a first configuration parameter, and indicates the PDCCH listening behavior of the MR after the first effective time according to the indication of the low-power wake-up signal.

[0310] Base station side:

[0311] Step 1: generating a low-power wake-up signal according to the first configuration parameter.

[0312] The low-power wake-up signal includes a first low-power wake-up signal and a second low-power wake-up signal. When the low-power wake-up signal indicates whether the main receiver starts to listen to the PDCCH, the low-power wake-up signal is described as the first low-power wake-up signal. When the low-power wake-up signal indicates whether the main receiver stops listening to the PDCCH, the low-power wake-up signal is described as the second low-power wake-up signal.

[0313] The first configuration parameter can include at least one of the following:

[0314] The first item: the length of the low-power wake-up signal, for example, 8 bits in length.

[0315] The second item: the indication mode of the low-power wake-up signal. The indication mode includes:

[0316] The first indication mode: payload-based indication mode (Payload-based indication mode), specifically, 1 bit indicates one information.

[0317] The second indication mode: sequence-based indication mode (Sequence-based indication mode), specifically, one sequence indicates one information.

[0318] In the second indication mode, the UE-ID related sequence length of 8 bits of the LP-WUS can be generated according to the formula or the mapping relationship.

[0319] The third item: the encoding mode.

[0320] The encoding mode is one of the following encoding modes:

[0321] Manchester encoding, PIE encoding, FM0 encoding, Miller encoding.

[0322] The Manchester encoding rule can be one of the rules in Table 1:

[0323] Table 1

[0324]

[0325] The fourth item: the time-frequency resource mapping mode, which is one of the following:

[0326] OOK-1: 1 bit information carried in one OFDM symbol: 1 represents all resource elements (REs) are all 1, 0 represents all REs are all mapped to 0;

[0327] OOK-4 with M: M bits of information carried in one OFDM symbol, corresponding to M OOK symbols, M = 1 / 2 / 4;

[0328] Fifth: a listening position parameter.

[0329] The listening position parameter can be one of the following:

[0330] Bit position; OFDM symbol index or OOK symbol index.

[0331] Sixth: a first effective time.

[0332] The main receiver performs or stops the listening of the PDCCH according to the indication of the first low-power wake-up signal or the second low-power wake-up signal after the first effective time.

[0333] The first effective time can be determined by at least one of the following:

[0334] B1: Different energy-saving states of the LP-WUR: 20 / 6 / 0 ms;

[0335] B2: Synchronization condition of the main receiver:

[0336] If the main receiver needs 1 synchronization signal and PBCH block (SSB) to complete synchronization, the corresponding first effective time is 20 ms;

[0337] If the main receiver needs 2 SSBs to complete synchronization, the corresponding first effective time is 40 ms;

[0338] If the main receiver needs 3 SSBs to complete synchronization, the corresponding first effective time is 60 ms.

[0339] B3: Processing time of the LP-WUS;

[0340] B4: Whether the LP-WUS carries Scell dormancy;

[0341] For example, the UE reports the values in Table 2 according to the energy-saving state and the synchronization condition of the main receiver, and the gNB determines the first effective time according to the reported values.

[0342] Table 2

[0343] UE capability 1 UE capability 2 20 ms 80 ms

[0344] In this first embodiment, the first effective time is represented by T1.

[0345] The power saving indication meaning of the low-power wake-up signal can be defined as one of the following:

[0346] Indicator meaning 1: 0 indicates MR is in hold state; 1 indicates MR is in change state;

[0347] Indicator meaning 2: 0 indicates that MR is in an active state, and 1 indicates that MR is in an inactive state;

[0348] Indicator meaning 3: 00 indicates that the master receiver is not woken up; 01 indicates that the master receiver is woken up; 10 indicates that the master receiver is in sleep mode; 11 indicates that the master receiver is not in sleep mode.

[0349] Step 2: The base station periodically sends a low-power wake-up signal according to the first cycle.

[0350] Specifically, the first cycle can have one of the following configurations:

[0351] Configuration 1: Cycle binding with C-DRX;

[0352] Configuration 2: A dedicated period, for example, 10ms, 20ms, ..., 120ms, 240ms. This period needs to be shorter than the C-DRX period to ensure that the MR has a low-power wake-up signal opportunity (LP-WUSOccasion, LO) in both active and inactive states. The low power in this embodiment can also be described as low power consumption.

[0353] like Figure 2 As shown, the C-DRX period is 320ms, the first period T1 is 120ms, and the first effective time S1 is 80ms. When the low-power wake-up signal is 01 (corresponding to the first low-power wake-up signal), it instructs the master receiver to wake up and start listening to the PDCCH. When the low-power wake-up signal is 10 (corresponding to the second low-power wake-up signal), it instructs the master receiver to stop listening to the PDCCH.

[0354] Terminal side:

[0355] Step 1: The first device periodically receives a low-power wake-up signal according to the first cycle.

[0356] The first device can be UE1, or the first device can be a low-power receiver of the second device (UE2), or the first device can be a first receiving capability, which is the ability to receive low-power wake-up signals using a low-power receiver, and the second device can be a second receiving capability, which is the ability to listen to the PDCCH using a master receiver.

[0357] The first device can receive the first period through a broadcast signal, a predefined manner, a high layer configured manner, and / or a DCI indicated manner. The broadcast signal can be a system information block (SIB) or a physical broadcast channel (PBCH).

[0358] Step 2: The first device decodes the low power wake-up signal according to the first configuration parameter.

[0359] The first configuration parameter is specifically the first configuration parameter in step 1 described above.

[0360] For example, the first device performs correlation detection on the received 8-bit low power wake-up signal and a local correlation sequence, and the result is 8, which is the sequence of the first device, and the MR is woken up. If the result is 0, the MR is not woken up.

[0361] Step 3: Perform corresponding operations according to the indication of the low power wake-up signal.

[0362] The indication of the low power wake-up signal includes one of the following meanings:

[0363] Under the indication meaning 1 described above: when the second device is in the first state (i.e. the inactive state), the first device receives the LP-WUS, and when the energy saving indication field is ‘1’, the MR enters the second state (i.e. the active state) after T1 time, otherwise the MR is in the first state. When the MR is in the second state, the first device receives the LP-WUS, and if the energy saving indication field is 1, the MR enters the first state after T1, otherwise the second device is in the first state.

[0364] Under the indication meaning 2: when the second device is in the first state, the first device receives the LP-WUS, and when the energy saving indication field is ‘1’, the second device continues to be in the first state, otherwise the MR enters the second state after T1 time. When the MR is in the second state, the first device receives the LP-WUS, and if the energy saving indication field is 1, the second device enters the first state after T1, otherwise continues to be in the second state.

When the first device is in the second state, the first device receives the LP-WUS, and when the energy saving indication field is ‘10’, the second device enters the first state after T1, otherwise continues to be in the second state.

[0366] In the embodiments of the present application, the behavior of the second device in the first state includes that the second device does not perform PDCCH monitoring; the behavior of the second device in the second state includes that the second device performs PDCCH monitoring.

[0367] Step 4: The behavior of the main receiver is performed after the first effective time.

[0368] The first effective time is a period of time after the first device receives the low-power wake-up signal.

[0369] The first effective time is determined according to at least one of the following:

[0371] Synchronization of the MR;

[0372] Processing time of the LP-WUS;

[0376] Base station side:

[0377] Step 1: Generate the first low-power wake-up signal according to the second configuration parameter.

[0378] The second configuration parameter includes at least one of the following:

[0379] The first item: the length of the first low-power wake-up signal, for example, 8 bits in length;

[0380] The second item: the indication mode of the first low-power wake-up signal. The indication mode includes:

[0381] The first indication mode: payload-based indication mode (Payload-based indication mode), specifically, 1 bit indicates one information; 8 bits of the first low-power wake-up signal can be used to indicate 8 UE wake-up or non-wake-up.

[0382] The second indication mode is a sequence-based indication mode. Specifically, one sequence indicates one information.

[0383] In the second indication mode, the UE-ID related sequence length of 8 bits can be generated according to a formula or a mapping relationship.

[0384] The third item is an encoding mode.

[0385] The encoding mode is the same as the encoding mode in the above embodiment one, which will not be repeated here.

[0386] The fourth item is a time-frequency resource mapping mode.

[0387] The time-frequency resource mapping mode is the same as the time-frequency resource mapping mode in the above embodiment one, which will not be repeated here.

[0388] The fifth item is a monitoring position parameter.

[0389] The monitoring position parameter is the same as the monitoring position parameter in the above embodiment one, which will not be repeated here.

[0390] The indication meaning of the first low-power wake-up signal includes at least one of the following:

[0391] Indication meaning 4-1: 0 indicates that the main receiver does not wake up; 1 indicates that the main receiver wakes up.

[0392] Indication meaning 4-2: 1 indicates that the main receiver does not wake up; 0 indicates that the main receiver wakes up.

[0393] Step 2: The base station sends the first low-power wake-up signal according to the fourth period.

[0394] Specifically, the fourth period can include one of the following configurations:

[0395] Configuration one: binding with the period of C-DRX;

[0396] Configuration two: a dedicated period, for example, 10 ms, 20 ms, …, 120 ms, 240 ms;

[0397] Step 3: The base station generates the second low-power wake-up signal according to the third configuration parameter.

[0398] The indication meaning of the second low-power wake-up signal includes one of the following indication meanings:

[0399] Indication meaning 5-1: 0 indicates that the main receiver goes to sleep (GTS); 1 indicates that the main receiver does not sleep.

[0400] Indication meaning 5-2: 1 indicates that the main receiver is in sleep mode; 0 indicates that the main receiver is not in sleep mode.

[0401] Step 4: The base station sends a second low-power wake-up signal according to the fifth cycle.

[0402] Specifically, the fifth cycle may include one of the following configurations:

[0403] Configuration 1: Periodic binding with C-DRX;

[0404] Configuration 2: A dedicated period, for example, 1ms or 2ms;

[0405] Configuration 3: Bind to the fourth cycle, for example, the fifth cycle = the fourth cycle / Y, where Y is a positive integer.

[0406] like Figure 3 As shown, the C-DRX period is 320ms, the fourth period T4 is 120ms, the fifth period T5 is 40ms, the fourth activation time S4 ​​is 80ms, and the fifth activation time S5 is 0ms. The first low-power wake-up signal is 1, indicating that the master receiver wakes up and starts listening to the PDCCH; the second low-power wake-up signal is 0, indicating that the master receiver stops listening to the PDCCH.

[0407] Terminal side:

[0408] Step 1: The first device receives the first low-power wake-up signal according to the fourth cycle.

[0409] Step 2: The first device demodulates the first low-power wake-up signal according to the second configuration parameters.

[0410] Specifically, the first device determines the bit position corresponding to the first low-power wake-up signal based on the monitoring position parameters, and determines the meaning of the first low-power wake-up signal indication based on the determined bit position.

[0411] The indication meaning of the first low-power wake-up signal includes at least one of the following meanings:

[0412] Indicator meaning 4-1: 0 indicates that the main receiver will not wake up; 1 indicates that the main receiver will wake up; that is, when the first low-power wake-up signal is 0, the main receiver will not wake up and will continue to sleep; otherwise, the main receiver will be woken up.

[0413] Meaning of Indication 4-2: 1 indicates that the master receiver will not wake up; 0 indicates that the master receiver will wake up. That is, when the first low-power wake-up signal is 1, it indicates that the master receiver will not wake up and will continue data transmission; otherwise, it will wake up the master receiver.

[0414] After the master receiver is woken up, it will listen to the PDCCH. If the master receiver is not woken up, it will not listen to the PDCCH.

[0415] Step 3: After the fourth effective time, the main receiver performs the corresponding action according to the instruction of the first low-power wake-up signal.

[0416] Step 4: The first device receives the second low-power wake-up signal according to the fifth cycle.

[0417] Step 5: The first device demodulates the second low-power wake-up signal according to the third configuration parameters.

[0418] Step 6: After the fifth effective time, the main receiver performs the corresponding action according to the instruction of the second low-power wake-up signal.

[0419] Example 3:

[0420] The low-power receiver periodically or aperiodically receives a first low-power wake-up signal according to the fourth configuration parameter. Based on the indication of the first low-power wake-up signal, it determines the PDCCH listening behavior of the MR after the sixth effective time. When the MR is in the active state, the MR receives a power-saving signal based on downlink control information (DCI-based power-saving signal) and a power-saving signal based on the media access control unit. Based on the DCI-based power-saving signal and the indication of MAC-CE, it determines the PDCCH listening behavior of the MR after the seventh or eighth effective time.

[0421] Base station side:

[0422] Step 1: The base station generates a first low-power wake-up signal based on the fourth or fifth configuration parameter.

[0423] The meaning of the first low-power wake-up signal can be found in the above-mentioned meaning 4-1 or meaning 4-2.

[0424] Step 2: The base station sends the first low-power wake-up signal according to the sixth or seventh cycle.

[0425] Step 3: Configure the base station to set the effective time of the DCI-based energy-saving signal to the seventh effective time, or configure the effective time of the MAC-CE-based energy-saving signal to the ninth effective time.

[0426] Step 4: The base station sends a DCI-based energy-saving signal or a MAC-CE-based energy-saving signal.

[0427] For example, such as Figure 4 As shown, the first low-power wake-up signal takes effect at the sixth effective time S6. This first low-power wake-up signal instructs the master receiver to start listening to the PDCCH. When the master receiver is in the active time, it receives a DCI-based power-saving signal. The power-saving signal takes effect at S6. This power-saving signal instructs the master receiver to stop listening to the PDCCH.

[0428] Terminal side:

[0429] Step 1: The first device receives a first low-power wake-up signal according to the sixth period or the seventh period.

[0430] Step 2: The first device demodulates the first low-power wake-up signal according to the fourth configuration parameter or the fifth configuration parameter.

[0431] Step 3: The first device performs the behavior indicated by the first low-power wake-up signal after the sixth effective time or the eighth effective time.

[0432] Step 4: The second device receives a DCI-based power saving signal or a MAC-CE-based power saving signal when in an active state.

[0433] Step 5: The second device performs the behavior indicated by the DCI-based power saving signal after the seventh effective time, or performs the behavior indicated by the MAC-CE-based power saving signal after the ninth effective time.

[0434] In the embodiment of the application, the main receiver of the terminal performs PDCCH monitoring based on the first low-power wake-up signal received by the low-power receiver, and controls the main receiver to stop monitoring the PDCCH in the case that the main receiver is instructed by the power saving signal to stop monitoring the PDCCH. Through the scheme, the monitoring of the PDCCH can be stopped in the case that the terminal is triggered to monitor the PDCCH by the LP-WUS, so that the integrity of the PDCCH monitoring process can be ensured.
