[0078] In some embodiments, low power receiver technology, namely low power wakeup radio (LP-WUR) technology or almost zero power wakeup radio (AZP-WUR) technology, is supported. The basic working principle of LP-WUR is that the receiving end includes a first module and a second module, as shown in FIG. Figure 2As shown, the first module is the main communication module, which is used for sending and receiving mobile communication data, and the second module is a low-power receiving module (also called a low-power wake-up receiving module), which is used to receive WUS, for example: a low power wake-up signal (LP-WUS). The terminal turns on the low-power receiving module to monitor WUS and turns off the main communication module in an energy-saving state. When downlink data arrives, the network will send WUS to the terminal. After the terminal monitors WUS through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments, and at this time the low-power receiving module enters the off state from the working state. The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive a low-power wake-up signal when it is turned on.
[0079] In some embodiments, in order to reduce the receiving activity of the terminal in the standby state, the radio frequency (RF) and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception, which can be achieved by introducing the above-mentioned low-power receiver in the receiving module of the terminal. In one embodiment, this near-zero-power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, and only relies on passive matching filtering and signal processing with low power consumption.
[0080] In some embodiments, WUS is some relatively simple on-off keying signals, and the time domain pattern of the on-off keying signal is as follows: Figure 3 As shown, the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes. In another embodiment, the low-power wake-up signal can be a frequency-shift keying (FSK) signal, an orthogonal frequency division multiplexing (OFDM) signal, or a hybrid signal of OFDM and on-off keying (OOK) or FSK. In addition, while the terminal turns on the low-power receiver to receive the wake-up signal, the main receiver module can maintain operation at a lower power consumption level, thereby achieving power saving by receiving the wake-up signal.
[0081] In some embodiments, the reception of WUS can be applied to a terminal in a radio resource control idle state or an inactive state (RRC_idle / inactive) or a terminal in a radio resource control connected state (RRC_connected), thereby achieving terminal energy saving.
[0082] In some embodiments, the OOK signal may be generated in an OFDM signal generation manner, for example, by sending or not sending an OFDM modulated sequence to indicate ON / OFF in the time domain. The OOK signal may be received using a receiver with lower power consumption.
[0083] In combination with the accompanying drawings, a PDCCH monitoring method, information sending method, apparatus and device provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.
[0084] See also Figure 4 , Figure 4 is a flow chart of a PDCCH monitoring method provided by an embodiment of the present application, such as Figure 4 As shown, the following steps are included:
[0085] Step 401: Under the first condition, the terminal monitors WUS;
[0086] Step 402: Under the second condition, the terminal monitors the PDCCH;
[0087] The first condition includes at least one of the following: the terminal sends first information, the terminal is in a first time period, and random access contention is successfully resolved;
[0088] The second condition includes: the terminal listening to the WUS instruction to wake up the terminal, or the terminal not listening to the WUS within the listening time period of the WUS;
[0089] The first information includes at least one of the following:
[0090] SR, NACK, BSR, BFR request, RACH, CCCH, CG;
[0091] The first time period includes at least one of the following:
[0092] The running time of the DRX retransmission timer (drx-retransmissiontimer);
[0093] During the SR pending period;
[0094] Random access response time window (ra-ResponseWindow);
[0095] Message B (MsgB) response time window (msgB-ResponseWindow);
[0096] The running time of the random access contention resolution timer (ra-ContentionResolutionTimer).
[0097] The above-mentioned first condition that the terminal monitors WUS can be understood as the terminal monitoring WUS when the first condition is met, or the terminal monitoring WUS during the time period included in the first condition. And the above-mentioned first condition can be a protocol agreement or a network side configuration, or determined autonomously by the terminal.
[0098] The above-mentioned first information may be information agreed upon in the protocol, or information indicated by the network side.
[0099] The first time period may be a time period agreed upon in the protocol, or a time period indicated by the network side.
[0100] The above-mentioned first condition includes that within the first time period, the terminal monitors WUS within the first time period.
[0101] The above-mentioned terminal monitoring WUS under the first condition may be that, under the first condition, the terminal starts or performs monitoring of WUS.
[0102] Optionally, the above-mentioned monitoring of PDCCH may be understood as resuming monitoring of PDCCH, or starting monitoring of PDCCH, or starting monitoring of PDCCH, or performing PDCCH monitoring.
[0103] In some implementations, the NACK may include at least one of the following:
[0104] NACK triggered by incorrect decoding of PDSCH;
[0105] NACK triggered by incorrect activation of PDSCH.
[0106] In some implementations, the BSR may include a BSR in at least one of the following formats:
[0107] Short BSR format, fixed size;
[0108] Long BSR format, variable size;
[0109] Short Truncated BSR format, fixed size;
[0110] Long Truncated BSR format, variable size.
[0111] In some implementations, the BSR may be a regular BSR, a periodic BSR, or a padding BSR defined in the protocol.
[0112] In the above implementation, the terminal may monitor WUS when sending at least one of the above items, such as monitoring WUS after sending at least one of the above items, so as to save power consumption of the terminal.
[0113] For example: when the first information includes RACH / BFR, when the terminal sends RACH / BFR, it starts / performs WUS monitoring, and does not perform / restore / start PDCCH monitoring or suspends PDCCH monitoring until the WUS instructs the terminal to wake up, or the terminal does not hear the WUS instructing the terminal to wake up and resumes PDCCH monitoring within the WUS monitoring time period; for another example, when the terminal sends RACH due to a positive SR, the terminal starts / performs WUS monitoring at the starting moment of the first time period (on the target cell), and does not (perform / restore / start) PDCCH or suspends PDCCH monitoring until the WUS instructs the terminal to wake up, or the terminal does not hear the WUS instructing the terminal to wake up and resumes PDCCH monitoring within the WUS monitoring time period, wherein the above-mentioned target cell is a secondary cell (Scell) or a primary cell (Pcell), or all service cells in a cell group.
[0114] The sending of RACH includes sending a preamble or a preamble sequence.
[0115] For another example: in the case where the random access contention is successfully resolved, if the terminal detects before this the indication information instructing the terminal to skip PDCCH monitoring (for a period of time), the terminal starts to start / perform WUS monitoring, and does not perform / resume / start PDCCH monitoring or suspends PDCCH monitoring until the WUS instructs the terminal to wake up, or the terminal does not hear the WUS instructing the terminal to wake up and resume PDCCH monitoring within the WUS monitoring time period;
[0116] In some embodiments, the above steps can realize first monitoring WUS within the above-mentioned at least one timer or time window to save power consumption, and then resume PDCCH monitoring when the WUS indication is heard to wake up the terminal, while also meeting data transmission requirements and delays.
[0117] In some implementations, the terminal may start monitoring the wake-up signal at the start time of the first time period.
[0118] Optionally, the terminal not listening to the WUS within the listening time period of the WUS may be that the terminal does not listen to a WUS instructing to wake up the terminal within the listening time period of the WUS, that is, the terminal not listening to the WUS means not listening to the WUS instructing to wake up the terminal.
[0119] In an embodiment, the terminal failing to monitor the WUS within the monitoring time period of the WUS may be that the terminal failing to monitor the WUS associated with the terminal within the monitoring time period of the WUS.
[0120] The above-mentioned second condition includes: the terminal listens to the WUS indication to wake up the terminal, or the terminal does not listen to the WUS within the listening time period of the WUS. It can be understood that the terminal listens to the WUS indication to wake up the terminal and the terminal does not listen to the WUS within the listening time period of the WUS are both the second conditions, but when executing step 402, only one of them is met, then PDCCH is monitored.
[0121] The WUS indicating waking up the terminal may be that the WUS triggers the terminal to monitor the PDCCH, or the WUS instructs the terminal to perform / resume PDCCH monitoring.
[0122] In the embodiment of the present application, the above steps can be used to achieve that under the first condition, the terminal can obtain energy-saving gain by monitoring the wake-up signal, thereby achieving terminal energy saving, and under the second condition, the terminal (resumes) monitoring the PDCCH, and can ensure that the communication requirements and communication delay are met. Therefore, through the embodiment of the present application, while ensuring that the communication delay is met, the terminal can obtain energy-saving gain by monitoring the wake-up signal, thereby achieving terminal energy saving.
[0123] As an optional implementation manner, under the first condition, the terminal monitors WUS includes: under the first condition, the terminal monitors the wake-up signal WUS, and the terminal needs to satisfy a first time interval that is less than or equal to a target threshold.
[0124] The first time interval is: the time interval allowed between the terminal monitoring the WUS and being able to monitor the PDCCH; the target threshold may be configured by the network side equipment or agreed upon by the protocol.
[0125] For example, under the first condition, the terminal monitors WUS and the terminal needs to meet the first time interval less than or equal to 3ms. 3ms is the target threshold value, which is configured by the network side device.
[0126] In order to meet the target threshold, the terminal needs to achieve that, under the first condition, the terminal cannot enter a too deep sleep state during monitoring WUS, that is, avoid the time interval between receiving the wake-up signal and resuming monitoring PDCCH to be greater than the target threshold.
[0127] As an optional implementation manner, when the terminal monitors the WUS, the terminal does not monitor the PDCCH.
[0128] Among them, the above-mentioned case where the terminal monitors WUS and the terminal does not monitor PDCCH can be that when the terminal monitors WUS, the terminal does not perform, resume, or start monitoring PDCCH, or suspends monitoring PDCCH until the above-mentioned second condition is met, and then the terminal monitors PDCCH.
[0129] In this implementation manner, when the terminal monitors the WUS, the terminal does not monitor the PDCCH, thereby further saving power consumption of the terminal.
[0130] As an optional implementation manner, the monitoring time period of the WUS includes at least one of the following:
[0131] the first time period;
[0132] The running time of the backoff timer.
[0133] Optionally, the terminal starts the backoff timer when starting to monitor the WUS, or the terminal resumes PDCCH monitoring when the backoff timer expires.
[0134] The back-off timer may be a back-off timer started when the terminal starts to perform WUS monitoring.
[0135] Optionally, when the terminal monitors a WUS instructing to wake up the terminal during the running of the back-off timer, the terminal stops running the back-off timer.
[0136] When the backoff timer expires, the terminal resumes PDCCH monitoring to avoid the situation where the terminal cannot respond to PDCCH monitoring in time because the terminal does not monitor the WUS indicating the terminal to wake up during the running time of the backoff timer, thereby ensuring communication transmission.
[0137] In this implementation, it is possible to monitor WUS during the first time period or the running time of the backoff timer, and to resume PDCCH monitoring when no WUS indicating waking up the terminal is monitored during the first time period or the running time of the backoff timer. This not only saves power consumption of the terminal, but also monitors PDCCH in a timely manner to improve the service performance of the terminal.
[0138] For example: if the terminal does not receive a WUS within the WUS monitoring time period, the terminal resumes PDCCH monitoring after the end of the time period. If the first information includes SR, the terminal does not receive a WUS during the SR pending period, then the PDCCH monitoring is resumed after the SR pending period ends; if the first information includes NACK, the terminal does not receive a WUS during the drx-retransmissiontimer period, then the PDCCH monitoring is resumed after the timer ends; if the WUS is not received within the first time period, the PDCCH monitoring is resumed after the first time period ends;
[0139] For another example, a backoff timer is obtained, and the terminal starts the backoff timer when starting to monitor the WUS; when the backoff timer expires, the terminal resumes monitoring the PDCCH.
[0140] As an optional implementation manner, the first condition further includes at least one of the following:
[0141] The terminal detects first indication information, where the first indication information is used to instruct the terminal to skip PDCCH monitoring or to instruct the terminal to skip PDCCH monitoring within a period of time;
[0142] SR suspension is canceled.
[0143] The first indication information may be indication information instructing the terminal to skip PDCCH monitoring for a period of time.
[0144] In one embodiment, the first indication information is DCI.
[0145] In some implementations, the terminal detects the first indication information, including at least one of the following:
[0146] After sending the first information, the terminal detects first indication information;
[0147] Before sending the first information, the terminal detects first indication information.
[0148] For example: when the terminal sends an SR and detects the first indication information after sending the SR, the terminal skips PDCCH monitoring according to the first indication information and performs WUS monitoring (during the duration of skipping PDCCH monitoring) until the WUS indication is heard to wake up the terminal and then the PDCCH monitoring is resumed, or the terminal does not hear the WUS indication to wake up the terminal within the WUS monitoring time period and resumes PDCCH monitoring.
[0149] For another example: when the terminal sends an SR and detects the first indication information before sending the SR, the terminal continues to skip PDCCH monitoring and starts WUS monitoring according to the first indication information, until it hears the WUS indication to wake up the terminal and then resumes PDCCH monitoring, or the terminal does not hear the WUS indication to wake up the terminal within the WUS monitoring time period and resumes PDCCH monitoring.
[0150] In one embodiment, after the terminal detects the first indication information indicating that the terminal skips (a period of time) the PDCCH, in the case where the pending SR is cancelled, the terminal does not resume the PDCCH monitoring of the target cell and starts the WUS monitoring until the WUS indication to wake up the terminal is heard and then resumes the PDCCH monitoring, or the terminal does not hear the WUS indicating the wake-up of the terminal within the WUS monitoring time period and resumes the PDCCH monitoring. The above-mentioned target cell is an Scell or a Pcell, or all serving cells in a cell group.
[0151] For another example: after the terminal detects the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time), the terminal sends a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or a physical uplink control channel (Physical Uplink Control Channel, PUCCH) carrying NACK, and the terminal continues to skip PDCCH monitoring and starts monitoring the wake-up signal until it hears the WUS instructing the terminal to wake up and then resumes PDCCH monitoring, or the terminal does not hear the WUS instructing the terminal to wake up within the WUS monitoring time period and resumes PDCCH monitoring.
[0152] For another example: when the terminal sends a NACK, when the DRX round trip time timer (drx-RTTtimer) or the drx-retransmissiontimer starts running, the monitoring of the wake-up signal is started / performed and the monitoring of the PDCCH is not started until the wake-up signal is monitored to indicate that the terminal wakes up, or the terminal does not listen to the WUS instructing to wake up the terminal within the WUS monitoring time period. The monitoring of the PDCCH is resumed;
[0153] For another example: when the terminal sends NACK and before or after it detects the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time), the terminal monitors the wake-up signal when the drx-RTTtimer or drx-retransmissiontimer starts running, and does not perform / resume / start PDCCH monitoring or suspends PDCCH monitoring until the wake-up signal is heard instructing the terminal to wake up, or the terminal does not hear the WUS instructing the terminal to wake up and resume PDCCH monitoring within the WUS monitoring time period.
[0154] In the above implementation, the above first condition may be extended by adding that the terminal detects first indication information indicating that the terminal skips PDCCH monitoring or SR suspension is cancelled, so as to further save power consumption of the terminal.
[0155] As an optional implementation manner, the starting time at which the terminal monitors the WUS includes at least one of the following:
[0156] Sending the start time of the next time unit of the time unit in which the first information is located;
[0157] The starting time domain position of SR suspension;
[0158] The start time of the DRX Round Trip Time (RTT) timer;
[0159] The start time of the DRX retransmission timer;
[0160] The start time of the first time unit after sending the Physical Uplink Shared Channel (PUSCH) carrying NACK;
[0161] The starting time of the first time unit after sending the Physical Uplink Control Channel (PUCCH) carrying NACK.
[0162] The start time of the first time period.
[0163] The above-mentioned time unit may be a time domain resource unit such as a time slot, a sub-time slot, or a symbol.
[0164] In the above implementation, the start time of monitoring the WUS can be flexibly determined, thereby meeting the requirements of various services or scenarios.
[0165] As an optional implementation manner, before the terminal monitors the WUS, the method further includes:
[0166] The terminal acquires configuration information, where the configuration information is used to indicate whether the terminal monitors the WUS under the first condition;
[0167] The terminal monitoring the wake-up signal WUS under the first condition includes:
[0168] In a case where the configuration information indicates that the terminal monitors WUS under the first condition, the terminal monitors WUS under the first condition.
[0169] The above configuration information may be configuration information sent by a receiving network side device.
[0170] The above-mentioned indication of whether the terminal monitors WUS under the first condition may be: indicating whether to replace the monitoring of PDCCH by the monitoring of WUS under the first condition.
[0171] In some implementations, the above configuration information may also be agreed upon by a protocol, for example, the protocol stipulates that the terminal monitors WUS under the first condition.
[0172] In this implementation, it can be determined based on the above configuration information that under the first condition, the WUS is monitored to save the power consumption of the terminal. For example, when the configuration information indicates that the monitoring of the WUS is started when the first information (such as NACK) is sent, the terminal monitors the WUS when the NACK is sent. For another example, when the configuration information indicates that the monitoring of the WUS is started when the DRX timer starts running, the terminal monitors the WUS when the DRX timer starts running. The DRX timer includes the two types of DRX timers mentioned above.
[0173] As an optional implementation manner, before the terminal monitors the WUS, the method further includes:
[0174] The terminal obtains indication information, where the indication information is used to determine a time to apply the WUS;
[0175] The terminal determines a time to apply the WUS based on the indication information.
[0176] The above-mentioned indication information may be indication information sent by the terminal and received by the network side device.
[0177] In some implementations, the above indication information may also be agreed upon by a protocol or pre-configured.
[0178] The above indication information is used to determine the time to apply the wake-up signal WUS, which can be understood as the terminal being able to determine the time to apply the WUS based on the content indicated by the above indication information.
[0179] The applying of WUS may include: monitoring WUS, or determining whether to monitor PDCCH based on WUS.
[0180] This implementation method determines the time to apply WUS based on the above indication information, thereby supporting the terminal to use WUS at that time, thereby saving power consumption of the terminal, for example: monitoring WUS during this time, but not monitoring PDCCH, and only monitoring PDCCH after monitoring WUS indicating to wake up the above terminal.
[0181] As an optional implementation manner, the indication information is used to indicate at least one of the following:
[0182] A time interval, wherein the time interval is a time interval between the indication information and the start of monitoring the WUS;
[0183] Skip PDCCH duration;
[0184] whether to apply the WUS during the skip PDCCH duration;
[0185] Whether to enable the discontinuous reception (DRX) duration associated with the indication information;
[0186] whether to apply the WUS in a DRX duration next to the DRX duration of the DRX duration receiving the indication information;
[0187] whether to apply the WUS in a DRX cycle next to the DRX cycle of which the indication information is received;
[0188] In a case where the indication information indicates not to enable the DRX duration associated with the indication information, whether to apply the WUS during the DRX duration.
[0189] The above time interval is the time interval between the start time of the next time unit after the terminal receives the time unit where the above indication information is located and the start time of starting to monitor the LP-WUS.
[0190] In some embodiments, the time interval indicated by the above-mentioned indication information may be a time interval indicated in at least one pre-acquired time interval, for example: before acquiring the above-mentioned indication information, the terminal acquires configuration information, and the configuration information is used to configure at least one time interval. In this way, the time interval indicated in at least one pre-acquired time interval can save the overhead of the indication information. For example: the network configures the values of multiple time intervals, and carries the above-mentioned indication information through downlink control information (Downlink Control Information, DCI), and the indication information indicates the application of one of the multiple time intervals, such as the indication information indicates the index of the above-mentioned time interval. In some embodiments, the above-mentioned DCI is a DCI carrying a PDCCH adaptation indication, for example, a DCI carrying a PDCCH skipping indication indication.
[0191] Among them, when the above indication information indicates to skip the PDCCH duration, the terminal can apply or not apply WUS in the PDCCH duration by default. When the above indication information indicates whether to turn on the DRX duration associated with the indication information, the terminal can apply or not apply WUS in the DRX duration by default.
[0192] In the above implementation, the time for applying WUS can be flexibly indicated through the above indication information, which is conducive to better saving the power consumption of the terminal. For example: the above indication information indicates the skipping PDCCH duration (such as the above indication information carries the skipping PDCCH duration indication (PDCCH skipping duration indication), the above indication information also indicates whether WUS is applied within the indicated PDCCH skipping duration, or the above indication information indicates whether WUS is applied within the next DRX duration / DRX cycle (DRX onduration / DRX cycle) of the terminal.
[0193] In this embodiment, the above steps can be used to determine the time to apply WUS based on the above indication information, thereby supporting the terminal to use WUS at this time, thereby saving power consumption of the terminal, for example: listening to WUS during this time, but not listening to PDCCH, and only listening to PDCCH after listening to WUS indicating to wake up the above terminal.
[0194] In the embodiment of the present application, under the first condition, the terminal monitors the wake-up signal WUS; under the second condition, the terminal monitors PDCCH; the first condition includes at least one of the following: the terminal sends the first information, the terminal is in the first time period, and the random access contention is successfully resolved; the second condition includes: the terminal monitors the WUS instruction to wake up the terminal, or the terminal does not monitor the WUS during the WUS monitoring time period. In this way, under the first condition, the terminal can obtain energy-saving gain by monitoring the wake-up signal to improve the power saving effect of the terminal, and under the second condition, the terminal monitors PDCCH to ensure communication requirements and communication delay.
[0195] The PDCCH monitoring method provided in the embodiment of the present application is illustrated by multiple scenarios below:
[0196] Scenario 1: If the terminal sends a PUCCH providing a positive SR before detecting a DCI, and the DCI format provides a PDCCH monitoring adaptation field instructing the terminal to skip PDCCH monitoring on the activated downlink bandwidth part (DL BWP) of the serving cell, then when SR is suspended, the terminal should monitor the PDCCH regardless of the PDCCH skipping indication on all serving cells of the corresponding cell group.
[0197] The processing method for scenario 1 is as follows:
[0198] When the terminal sends an SR and the SR is pending, the terminal monitors the WUS and does not (perform / resume / start) the PDCCH or suspends the PDCCH monitoring until a wake-up signal is heard instructing the terminal to wake up and resume the PDCCH monitoring, or the terminal does not hear a WUS instructing the terminal to wake up and resume the PDCCH monitoring within the WUS monitoring time period.
[0199] Scenario 2: If the terminal sends a PUCCH providing a positive SR after the terminal detects the DCI, the terminal starts resuming PDCCH monitoring at the beginning of the first time slot after the last symbol of PUCCH transmission in all serving cells of the corresponding cell group.
[0200] The processing method for scenario 2 is as follows:
[0201] When the terminal sends an SR and detects the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time) after sending the SR, the terminal skips PDCCH monitoring according to the first indication information for skipping PDCCH monitoring and performs WUS monitoring (during the duration of skipping PDCCH monitoring) until the terminal is awakened by the WUS, or the terminal does not hear the WUS instructing the terminal to wake up within the WUS monitoring time period and resumes PDCCH monitoring.
[0202] Scenario 3: After the terminal detects a DCI format providing a PDCCH monitoring adaptation field, which instructs the terminal to skip the PDCCH monitoring duration on the activated DL BWP of the serving cell, when the SR suspension is canceled, the terminal resumes PDCCH monitoring in all serving cells of the corresponding cell group.
[0203] The processing method for scenario 3 is as follows:
[0204] When the terminal sends an SR and detects the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time) before sending the SR, the terminal continues to skip PDCCH monitoring and starts listening to WUS until it hears the WUS instructing the terminal to wake up and then resumes PDCCH monitoring, or the terminal does not hear the WUS instructing the terminal to wake up within the WUS listening time period and then resumes PDCCH monitoring.
[0205] Scenario 4: PDCCH monitoring cannot be skipped within a specific time period, for example: during the ra-ResponseWindow or msgBResponseWindow, or during the duration of the ra ContentionResolutionTimer running, the terminal should not skip PDCCH monitoring on the special cell (SpCell), or, if the terminal sends RACH due to a positive SR, then during the ra ResponseWindow or msgB ResponseWindow or the duration of the raContentionResolutionTimer running, the terminal should not skip PDCCH monitoring of any serving cell of the corresponding cell group.
[0206] The processing method for scenario 4 is as follows:
[0207] During the time of the above-mentioned ra-ResponseWindow or msgB ResponseWindow, or during the duration of the raContentionResolutionTimer, continue to skip PDCCH monitoring and start WUS monitoring until the WUS instructs the terminal to wake up and then resume PDCCH monitoring, or the terminal does not hear the WUS instructing to wake up the terminal during the WUS monitoring time period and resumes PDCCH monitoring.
[0208] Scenario 5: After the contention is resolved successfully, PDCCH monitoring cannot be skipped. For example, after the terminal detects DCI, which provides a PDCCH monitoring adaptation field, which indicates that the terminal skips the PDCCH monitoring duration on the activated DL BWP of the SpCell, when the random access contention is resolved successfully, the terminal resumes PDCCH monitoring on the SpCell.
[0209] The processing method for scenario 5 is as follows:
[0210] In the case where the contention is successfully resolved, if the terminal has previously detected the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time), the terminal starts to start / conduct monitoring of the wake-up signal, and does not (conduct / resume / start) or suspends monitoring of PDCCH until a wake-up signal is heard instructing the terminal to wake up, or the terminal does not hear the WUS instructing the terminal to wake up and resumes PDCCH monitoring within the WUS monitoring time period.
[0211] Scenario 6: The terminal resumes PDC cycle monitoring when it sends NACK during the PDCCH skipping duration, for example: when the terminal is configured with post-NACH PDCCH resumption monitoring, after the terminal detects DCI, if the UE sends PUCCH or PUSCH providing a NACK value due to incorrect decoding of the PDSCH scheduled / activated by the DCI received from the serving cell, the terminal terminates PDCCH skipping from the beginning of the first time slot after the last symbol of the PUCCH or PUSCH transmission in the serving cell.
[0212] The processing method for scenario 6 is as follows:
[0213] After the terminal detects the first indication information instructing the terminal to skip PDCCH monitoring (for a period of time), the terminal sends a PUCCH or PUSCH carrying NACK, and the terminal continues to skip PDCCH monitoring and starts to monitor the wake-up signal until the wake-up signal instructs the terminal to wake up, or the terminal does not hear the WUS resumption PDCCH monitoring instructing to wake up the terminal within the WUS listening time period.
[0214] In the embodiments of the present application, based on the above-mentioned scenarios in which the terminal can resume PDCCH monitoring under some specific conditions, combined with the use of WUS, since WUS monitoring can save more power than PDCCH monitoring, the terminal does not need to blindly resume PDCCH monitoring in these scenarios. Instead, it first monitors WUS to determine whether there is a PDCCH sending demand on the network side, and then wakes up the terminal by sending WUS to resume PDCCH monitoring, thereby achieving further power saving effect.
[0215] See also Figure 5 , Figure 5 is a flow chart of a time determination method provided in an embodiment of the present application, such as Figure 5 As shown, the following steps are included:
[0216] Step 501: The terminal obtains indication information, where the indication information is used to determine the time to apply WUS;
[0217] Step 502: The terminal determines the time to apply the WUS based on the indication information.
[0218] The above-mentioned indication information may be indication information sent by the terminal and received by the network side device.
[0219] In some implementations, the above indication information may also be agreed upon by a protocol or pre-configured.
[0220] The above indication information is used to determine the time to apply the wake-up signal WUS, which can be understood as the terminal being able to determine the time to apply the WUS based on the content indicated by the above indication information.
[0221] The applying of WUS may include: monitoring WUS, or determining whether to monitor PDCCH based on WUS.
[0222] In this embodiment, since the time to apply WUS is determined based on the above indication information, the terminal is supported to use WUS at this time, thereby saving power consumption of the terminal. For example, WUS is monitored during this time, but PDCCH is not monitored, and PDCCH is monitored only after WUS indicating to wake up the above terminal is monitored.
[0223] As an optional implementation manner, the indication information is used to indicate at least one of the following:
[0224] A time interval, wherein the time interval is a time interval between the indication information and the start of monitoring the WUS;
[0225] Skip PDCCH duration;
[0226] whether to apply the WUS during the skip PDCCH duration;
[0227] Whether to enable the discontinuous reception (DRX) duration associated with the indication information;
[0228] whether to apply the WUS in a DRX duration next to the DRX duration of the DRX duration receiving the indication information;
[0229] whether to apply the WUS in a DRX cycle next to the DRX cycle of which the indication information is received;
[0230] In a case where the indication information indicates not to enable the DRX duration associated with the indication information, whether to apply the WUS during the DRX duration.
[0231] The above time interval is the time interval between the start time of the next time unit after the terminal receives the time unit where the above indication information is located and the start time of starting to monitor the LP-WUS.
[0232] In some embodiments, the time interval indicated by the above-mentioned indication information may be a time interval indicated in at least one pre-acquired time interval, for example: before acquiring the above-mentioned indication information, the terminal acquires configuration information, and the configuration information is used to configure at least one time interval. In this way, the time interval indicated in at least one pre-acquired time interval can save the overhead of the indication information. For example: the network configures the values of multiple time intervals, and carries the above-mentioned indication information through downlink control information (Downlink Control Information, DCI), and the indication information indicates the application of one of the multiple time intervals, such as the indication information indicates the index of the above-mentioned time interval. In some embodiments, the above-mentioned DCI is a DCI carrying a PDCCH adaptation indication, for example, a DCI carrying a PDCCH skipping indication indication.
[0233] Among them, when the above indication information indicates to skip the PDCCH duration, the terminal can apply or not apply WUS in the PDCCH duration by default. When the above indication information indicates whether to turn on the DRX duration associated with the indication information, the terminal can apply or not apply WUS in the DRX duration by default.
[0234] In the above implementation, the time for applying WUS can be flexibly indicated through the above indication information, which is conducive to better saving the power consumption of the terminal. For example: the above indication information indicates the skipping PDCCH duration (such as the above indication information carries the skipping PDCCH duration indication (PDCCH skipping duration indication), the above indication information also indicates whether WUS is applied within the indicated PDCCH skipping duration, or the above indication information indicates whether WUS is applied within the next DRX duration / DRX cycle (DRX onduration / DRX cycle) of the terminal.
[0235] In this embodiment, the above steps can be used to determine the time to apply WUS based on the above indication information, thereby supporting the terminal to use WUS at this time, thereby saving power consumption of the terminal, for example: listening to WUS during this time, but not listening to PDCCH, and only listening to PDCCH after listening to WUS indicating to wake up the above terminal.
