The character " / " generally represents an "or" relationship between the associated objects. In the embodiments of the present disclosure, the term "a plurality of" means two or more, and other quantifiers are similar.

[0176] In the embodiments of the present disclosure, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words "exemplary" or "for example" is intended to present relevant concepts in a specific way.

[0177] In order for those skilled in the art to better understand the embodiments of the present disclosure, the following description is first made.

[0178] I. Low Power Wake-up Signal (LP-WUS) and Low Power Wake Up Receiver (LP-WUR);

[0179] 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 FIG. 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 power of the terminal.

[0180] (II) Connected-discontinuous reception (C-DRX) in the connected state;

[0181] DRX is a function introduced by a user equipment (UE) for power saving, which is configured by a radio resource control (RRC) layer. In the connected state, if the RRC layer configures the medium access control (MAC) layer with the DRX function, the UE can intermittently monitor the PDCCH in the physical layer; otherwise, the UE must continuously monitor the PDCCH. In the RRC connected state, after the network configures the C-DRX function:

[0182] (1) The UE listens to the PDCCH channel according to the DRX cycle configured by the base station.

[0183] (2) In the on duration time, the UE normally monitors the PDCCH channel, and after the on duration, the UE can enter the DRX state, i.e., the sleep state, to save energy consumption.

[0184] (3) After the UE enters the sleep state, if there is downlink data to arrive, the base station cannot perform downlink PDCCH scheduling.

[0185] (III) Related timers of DRX;

[0186] (1) DRX continuous monitoring timer (drx-onDurationTimer): from the start of a DRX cycle, during the running of the timer, the UE needs to continuously monitor the PDCCH subframe number of the PDCCH of the network.

[0187] (2) DRX inactivity timer (drx-InactivityTimer): The timer is started after the UE receives new data scheduling PDCCH signaling. The parameter indicates the number of consecutive PDCCH subframes in the active state that the UE needs to continue to monitor after successfully decoding the DCI of a downlink PDCCH channel.

[0188] (3) Downlink Hybrid Automatic Repeat reQuest Round Trip Time (HARQ RTT) timer: The length of the timer is the minimum time interval from the HARQ feedback time to the reception of the HARQ retransmission for the process. Only when the data corresponding to the downlink process is not successfully decoded, the terminal will start at the first symbol after the HARQ negative acknowledgment (NACK) feedback of the process. The retransmission scheduling of the downlink process will be scheduled after the timing value of the timer.

[0189] (4) DRX downlink retransmission timer (drx-RetransmissionTimerDL): The time slot length value of the bandwidth part (BWP) receiving the transport block.

[0190] (Four) LP-WUS;

[0191] The current LP-WUS supports On-Off Keying (OOK)-1 and OOK-4.

[0192] OOK-1: One OFDM symbol corresponds to a single bit, and the subcarriers (SCs) of the LP-WUS are:

[0193] OOK=1 means that all SCs are used for modulation;

[0194] OOK=0 means that all SCs are zero power (from the perspective of baseband).

[0195] 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 square transform.

[0196] The signal processing method provided by the embodiments of the present disclosure will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0273] In some embodiments, the sixth period is configured according to at least one of: a period of C-DRX; a sixth dedicated period.

[0274] For example, the sixth period can be a period of C-DRX divided by X, X being a positive integer. The above-mentioned sixth dedicated period comprises a plurality of preset values, such as 1 ms, 2 ms, etc.

[0280] In some embodiments, the indication information field comprises at least one of the following:

[0282] The information indication field in the embodiments of the present disclosure can be a newly added indication field, such as the sleep state indication field described above, and the length of the newly added indication field and the indication field is 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 demodulation reference signal (DMRS) sequence initialization information field, and a carrier indication field (for scheduling PDCCH).

[0283] 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 power saving signal is added in the PDCCH monitoring adaptation indication field in the DCI.

[0284] A5: a bit length of the indication information field;

[0289] In the embodiments of the present disclosure, the power saving signal based on the downlink control information can be a dedicated DCI, a scheduling PDCCH, and / or a non-scheduling PDCCH. In the case of a dedicated DCI, the first receiving parameter of the power saving signal based on the downlink control information includes at least one of A1-A5.

For example, the seventh validity 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 primary 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 primary receiver does not enter the dormant state and continues to monitor the PDCCH.

[0296] The seventh effective time is a time period between a time when the main receiver receives the power saving signal based on the downlink control information and a time when information indicated by the power saving signal takes effect.

[0308] The signal processing method of the present disclosure will be described in detail below in combination with embodiments.

[0309] Embodiment one:

[0310] The low-power receiver receives the low-power wake-up signal according to the first configuration parameter at a first period, and according to the indication of the low-power wake-up signal, instructs the PDCCH monitoring behavior of the MR after the first effective time.

[0311] Base station side:

[0312] Step 1: generating a low-power wake-up signal according to the first configuration parameter.

[0313] 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 monitoring the PDCCH, the low-power wake-up signal is described as the first low-power wake-up signal, and when the low-power wake-up signal indicates whether the main receiver stops monitoring the PDCCH, the low-power wake-up signal is described as the second low-power wake-up signal.

[0319] In the second indication method, the UE-ID related sequence length of 8 bits of the LP-WUS can be generated according to the formula or the mapping relationship.

[0320] The third item: the encoding method;

[0321] The encoding method is one of the following encoding methods:

[0322] Manchester encoding, PIE encoding, FM0 encoding, Miller encoding.

[0323] The Manchester encoding rule can be one of the rules in Table 1:

[0324] Table 1

[0325] The fourth item is a time-frequency resource mapping manner, and the time-frequency resource mapping manner is one of the following:

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

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

[0328] The fifth item is a monitoring position parameter.

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

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

[0331] The sixth item is a first effective time.

[0332] The main receiver performs monitoring or stops 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 / physical broadcast channel signal 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 LP-WUS;

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

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

[0342] Table 2

[0343] In the first embodiment, the first effective time is represented by T1.

[0344] The power saving indication meaning of the low-power wake-up signal can be one of the following definitions:

[0345] Indication meaning 1: 0 indicates that the MR remains in the state; 1 indicates that the MR changes the state;

[0346] Indication meaning 2: 0 indicates that the MR is in the active state, and 1 indicates that the MR is in the inactive state;

[0347] Indication meaning 3: 00 indicates that the main receiver does not wake up; 01 indicates that the main receiver wakes up; 10 indicates that the main receiver sleeps; and 11 indicates that the main receiver does not sleep.

[0348] Step 2: The base station periodically transmits a low-power wake-up signal according to the first period.

[0349] Specifically, the first period can be one of the following configurations:

[0350] Configuration one: binding with the period of C-DRX;

[0351] Configuration two: a dedicated period, for example, 10ms, 20ms, …, 120ms, 240ms, which needs to be less than the period of C-DRX to ensure that the MR has a low-power wake-up signal occasion (LP-WUS Occasion, LO) in the active state and the inactive state. The low power in the embodiments of the present disclosure can also be described as low power consumption.

[0352] As shown in FIG. 2, the period of C-DRX 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 (the low-power wake-up signal corresponds to the first low-power wake-up signal), it indicates that the main receiver wakes up and starts to monitor PDCCH. When the low-power wake-up signal is 10 (the low-power wake-up signal corresponds to the second low-power wake-up signal), it indicates that the main receiver stops monitoring PDCCH.

[0357] Step 2: The first device decodes the low-power wake-up signal according to a first configuration parameter.

[0358] The first configuration parameter is specifically the first configuration parameter in step 1.

[0359] 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.

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.

[0391] Indication meaning 4-2: 1 indicates that the main receiver does not wake up; 0 indicates that the main receiver wakes up.

[0392] Step 2: the base station sends the first low-power wake-up signal according to the fourth period.

[0393] Specifically, the fourth period can include one of the following configurations:

[0394] Configuration one: binding with the period of C-DRX;

[0395] Configuration two: a dedicated period, for example, 10 ms, 20 ms, …, 120 ms, 240 ms;

[0396] Step 3: the base station generates the second low-power wake-up signal according to the third configuration parameter.

[0397] The indication meaning of the second low-power wake-up signal includes one of the following indication meanings:

[0398] Indication meaning 5-1: 0 indicates the main receiver to sleep (Go to sleep, GTS); 1 indicates the main receiver not to sleep;

[0399] Indication meaning 5-2: 1 indicates the main receiver to sleep; 0 indicates the main receiver not to sleep.

[0400] Step 4: The base station sends the second low-power wake-up signal according to the fifth period.

[0401] Specifically, the fifth period can include one of the following configurations:

[0402] Configuration one: binding with the period of C-DRX;

[0403] Configuration two: a dedicated period, for example, 1ms, 2ms;

[0404] Configuration three: binding with the fourth period, for example, the fifth period = the fourth period / Y, Y is a positive integer.

[0405] As shown in FIG. 3, the period of C-DRX is 320ms, the fourth period T4 is 120ms, the fifth period T5 is 40ms, the fourth effective time S4 is 80ms, and the fifth effective time S5 is 0ms. The first low-power wake-up signal is 1, indicating that the main receiver wakes up and starts to monitor PDCCH, and the second low-power wake-up signal is 0, indicating that the main receiver stops monitoring PDCCH.

[0406] Terminal side:

[0407] Step 1: The first device receives the first low-power wake-up signal according to the fourth period.

[0408] Step 2: The first device demodulates the first low-power wake-up signal according to the second configuration parameter.

[0409] Specifically, the first device determines the bit position corresponding to the first low-power wake-up signal according to the monitoring position parameter, and determines the indication meaning of the first low-power wake-up signal based on the determined bit position.

[0410] The indication meaning of the first low-power wake-up signal includes at least one of the following meanings:

[0411] Indication meaning 4-1: 0 indicates that the main receiver does not wake up; 1 indicates that the main receiver wakes up; that is, when the first low-power wake-up signal is 0, the main receiver does not wake up and continues to sleep, otherwise the main receiver wakes up;

[0412] Indication meaning 4-2: 1 indicates that the main receiver does not wake up; 0 indicates that the main receiver wakes up. That is, when the first low-power wake-up signal is 1, it indicates that the main receiver does not wake up and continues to sleep, otherwise the main receiver wakes up.

[0413] The main receiver wakes up and monitors the PDCCH. When the main receiver does not wake up, the PDCCH is not monitored.

[0414] Step 3: The main receiver performs corresponding actions according to the indication of the first low-power wake-up signal after the fourth effective time.

[0415] Step 4: The first device receives the second low-power wake-up signal according to the fifth period.

[0419] The low-power receiver periodically or aperiodically receives the first low-power wake-up signal according to the fourth configuration parameter, and determines the PDCCH monitoring behavior of the MR after the sixth effective time according to the indication of the first low-power wake-up signal. When the MR is in an active state, the MR receives a DCI-based energy saving signal and a MAC-CE-based energy saving signal, and determines the PDCCH monitoring behavior of the MR after the seventh effective time or the eighth effective time according to the indication of the DCI-based energy saving signal and the MAC-CE.

[0420] Base station side:

[0421] Step 1: The base station generates the first low-power wake-up signal according to the fourth configuration parameter or the fifth configuration parameter.

[0422] The indication of the first low-power wake-up signal can refer to the indication meaning 4-1 or the indication meaning 4-2 described above.

[0423] Step 2: The base station transmits the first low-power wake-up signal according to the sixth period or the seventh period.

[0424] Step 3: The base station configures the effective time of the DCI-based energy saving signal as the seventh effective time, or configures the effective time of the MAC-CE-based energy saving signal as the ninth effective time.

[0425] Step 4: The base station transmits the DCI-based energy saving signal or the MAC-CE-based energy saving signal.

[0426] For example, as shown in FIG. 4, the validity time of the first low-power wake-up signal is the sixth validity time S6, the first low-power wake-up signal instructs the main receiver to start monitoring the PDCCH, and the DCI-based power saving signal is received at the main receiver in the active time, the validity time of the power saving signal is S6, and the power saving signal instructs the main receiver to stop monitoring the PDCCH.

[0427] Terminal side:

[0428] Step 1: The first device receives the first low-power wake-up signal according to the sixth period or the seventh period.

[0429] Step 2: The first device demodulates the first low-power wake-up signal according to the fourth configuration parameter or the fifth configuration parameter.

[0430] Step 3: The first device performs the behavior indicated by the first low-power wake-up signal after the sixth validity time or the eighth validity time.

[0431] Step 4: The second device receives the DCI-based power saving signal or the MAC-CE-based power saving signal in the active state.

[0432] Step 5: The second device performs the behavior indicated by the DCI-based power saving signal after the seventh validity time, or performs the behavior indicated by the MAC-CE-based power saving signal after the ninth validity time.

[0433] In the embodiment of the present disclosure, the main receiver of the terminal monitors the PDCCH 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 when the power saving signal instructs the main receiver to stop monitoring the PDCCH. Through this scheme, the monitoring of the PDCCH can be stopped when the terminal is triggered to monitor the PDCCH by the LP-WUS, thereby ensuring the integrity of the PDCCH monitoring process.

[0434] As shown in FIG. 5, the present disclosure provides a signal processing method, which is executed by a network side device, and the method comprises:
