This disclosure relates to the field of communication, and more particularly, to a method for information processing and a communication apparatus.
At present, processing of a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) burst and physical downlink control channel (PDCCH) monitoring both require use of a regular receiver (namely, a receiver used in an idle state/an inactive state/a connected state). Therefore, when a terminal device wakes up from deep sleep, power (energy) consumption is high, and power consumption in detecting a paging early indication (PEI) is also high. The overall receiver may also be referred to as a regular receiver, and has a complete radio frequency and baseband processing architecture. The overall receiver may include an SSB receiving module and a data/control receiving module with regard to division of functional modules.
For the case where the terminal device wakes up from deep sleep, in order to reduce power consumption in state transition and power consumption in signal detection, a low-power receiver (also known as low-power wake-up receiver) independent of the overall receiver may be adopted to detect a wake-up signal. After the wake-up signal is detected, the low-power receiver notifies the overall receiver, and then the overall receiver is turned on and performs measurement and data transmission and reception (for example, receive a paging message). There is a time interval between when the wake-up signal is received by the low-power receiver and when the overall receiver can perform data transmission and reception, but such time interval may increase delay in data transmission of the terminal device. Therefore, how to reduce delay in data transmission is a problem to be solved.
The disclosure provides a method for information processing and a communication apparatus, which are beneficial to reducing delay in data transmission.
In a first aspect, a method for information processing is provided in the disclosure. The method includes: detecting a wake-up signal, and monitoring a physical downlink control channel (PDCCH) after a first time point.
In the method described in the first aspect, a terminal device detects a wake-up signal, and performs PDCCH monitoring after the first time point. In this way, it is beneficial to reducing delay in data transmission and improving data transmission efficiency.
In a possible implementation, the PDCCH is monitored after the first time point as follows. Monitor a PDCCH in N slots within a 1st duration that is after the first time point, where N is a positive integer; or monitor a PDCCH in a 1st slot that is after the first time point.
In a possible implementation, the PDCCH is monitored after the first time point as follows. Monitor a PDCCH in W slots within first X durations that are after the first time point or a PDCCH within first X slots that are after the first time point, where X and W each are a positive integer; or monitor a PDCCH in first K slots that are after the first time point, where K is a positive integer.
In a possible implementation, the PDCCH is monitored after the first time point as follows. Monitor a PDCCH within a time window that is after the first time point.
In a possible implementation, the first time point equals to a second time point plus a first time interval. In this way, it is possible to ensure that there is a time interval for turning on an overall receiver.
In a possible implementation, the first time interval includes a second time interval plus a time interval related to a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) period or an SS burst period. In this way, one or more SSBs or SS bursts can be processed after an overall receiver is turned on, thereby realizing time-frequency synchronization and/or measurement.
In a possible implementation, the first time interval includes a second time interval plus Y SSB periods, where Y is a positive integer. Alternatively, the first time interval includes a second time interval plus R SSB burst periods, where R is a positive integer.
In a possible implementation, the first time interval includes an interval between a third time point and a slot in which M SSBs or SS bursts closest to the third time point are located, and the third time point equals to the second time point plus a second time interval, where M is a positive integer. In this way, it is possible to ensure that there is a reference time point after an overall receiver is turned on.
In a possible implementation, the first time interval includes a second time interval plus C SSB periods and D tracking reference signal periods, where C and D each are a positive integer. In this way, a network device can send a tracking reference signal after sending the wake-up signal, so as to facilitate time-frequency synchronization and/or measurement of an overall receiver.
In a possible implementation, the first time interval includes an interval between a third time point and a slot in which E SSBs and F tracking reference signals closest to the third time point are located, and the third time point equals to the second time point plus a second time interval, where E and F each are a positive integer. In this way, it is possible to ensure that there is a reference time point after an overall receiver is turned on.
In a possible implementation, the first time interval includes a second time interval plus a period of a preamble sequence. In this way, a network device can send a preamble after sending the wake-up signal, so as to facilitate time-frequency synchronization and/or measurement of an overall receiver.
In a possible implementation, the first time interval includes an interval between a third time point and a slot in which a preamble sequence closest to the third time point is located, and the third time point equals to the second time point plus a second time interval. In this way, it is possible to ensure that there is a reference time point after an overall receiver is turned on.
In a possible implementation, the second time point is a position in a sequence of the wake-up signal. In this way, it is possible to ensure that there is a reference time point for a terminal device and a network device.
In a possible implementation, the second time point is an ending position of a sequence of the wake-up signal.

In the method described in the second aspect, the terminal device receives the wake-up signal, where the wake-up signal includes the UE group information. In this way, whether a UE group corresponding to a paging occasion (PO) is woken up can be determined by detecting a wake-up signal, thereby reducing unnecessary power consumption of the terminal device.
In a possible implementation, the UE group information includes a UE group identity (ID).
In a possible implementation, the UE group ID is calculated based on a UE ID, a first higher-layer parameter, and a second higher-layer parameter.
In a possible implementation the UE group ID includes a first ID and a second ID.
In a possible implementation, the first ID is calculated based on a UE ID and a first higher-layer parameter. The second ID is calculated based on the UE ID and a second higher-layer parameter. In this way, it is possible to ensure that a UE group is equivalent to a UE group corresponding to a PO.
In a possible implementation, the first ID is a remainder obtained by dividing a UE ID by a first higher-layer parameter. The second ID is a remainder obtained by dividing the UE ID by a second higher-layer parameter.
In a possible implementation, the UE group ID is a remainder obtained by dividing a UE ID by a target parameter, and the target parameter is a product of a first higher-layer parameter and a second higher-layer parameter.
In a possible implementation, the first higher layer parameter is a higher-layer parameter that is related to UE subgrouping and used for calculating a paging frame (PF).
In a possible implementation, the second higher layer parameter is a higher-layer parameter related to UE subgrouping and used for calculating a PO.

Firstly, some terms involved in the embodiments of the disclosure will be explained to facilitate understanding of those skilled in the art.
Embodiments of the disclosure may be applied to a network architecture illustrated in
It should be noted that, at present, processing of an SSB burst and physical downlink control channel (PDCCH) monitoring both require use of an overall receiver (namely, a receiver used in an idle state/an inactive state/a connected state). Therefore, when the terminal device wakes up from sleep, power (energy) consumption in such conversion is high, and power consumption in detecting a paging-related PDCCH or paging early indication (PEI) is also high. The overall receiver may also be referred to as a regular receiver, and has a complete radio frequency and baseband processing architecture. The overall receiver may include an SSB receiving module and a data/control receiving module with regard to division of functional modules.
For the case where the terminal device wakes up from deep sleep, in order to reduce power consumption in such conversion and power consumption in signal detection, a low-power receiver independent of the overall receiver may be adopted to detect a wake-up signal. After the wake-up signal is detected, the low-power receiver notifies the overall receiver, and then the overall receiver is turned on and performs measurement and data transmission and reception (for example, receive a paging message). There is a time interval between when the wake-up signal is received by the low-power receiver and when the overall receiver can perform data transmission and reception, but such time interval may increase delay in data transmission of the terminal device. Therefore, how to reduce delay in data transmission is a problem to be solved.
In order to reduce delay in data transmission and improve data transmission efficiency, embodiments of the disclosure provide a method for information processing. In order for better understanding of the method for information processing provided in embodiments of the disclosure, the method for information processing will be described in detail below.
Referring to
201, a terminal device detects a wake-up signal.
In embodiments of the disclosure, the terminal device may receive the wake-up signal sent by a network device, where the wake-up signal is used for waking up the terminal device to perform PDCCH monitoring.
Optionally, the terminal device is configured with a low-power receiver and an overall receiver, where the low-power receiver is configured to detect the wake-up signal. After the wake-up signal is detected by the low-power receiver, the low-power receiver notifies the overall receiver, and then the overall receiver is turned on and performs PDCCH monitoring.
Optionally, the wake-up signal may include UE group information. By detecting the UE group information in the wake-up signal, the terminal device may determine whether to wake up, thereby reducing power consumption of the terminal device.
202, the terminal device monitors a PDCCH(s) after a first time point.
In embodiments of the disclosure, since a PDCCH is configured based on a search space set (SSS) and is periodic, after the first time point is agreed between the network device and the terminal device, the network device may start sending a PDCCH and the terminal device may start monitoring the PDCCH. The PDCCH may be a paging PDCCH or a paging indication PDCCH, which is not limited herein. In this way, it is beneficial to reducing delay in data transmission and improving data transmission efficiency.
The term “monitoring a PDCCH” in embodiments of the disclosure is equivalent to “monitoring a PDCCH monitoring occasion”.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in N slots within a 1st duration that is after the first time point, where N is a positive integer. In this way, the terminal device may need to monitor a PDCCH(s) in multiple slots within the 1st duration that is after the first time point, thereby improving reliability of PDCCH monitoring.
Exemplarily, as illustrated in
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in a 1st slot that is after the first time point. In this way, the terminal device only needs to monitor the PDCCH in the 1st slot that is after the first time point, thereby reducing PDCCH monitoring of the terminal device.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in a 1st slot that is after the first time point if the duration is not configured. In this way, if no duration is configured, the terminal device only needs to monitor the PDCCH in the 1st slot that is after the first time point, and as such, a base station can control the terminal device to reduce PDCCH monitoring of the terminal device.
Exemplarily, as illustrated in
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in first T slots within a 1st duration that is after the first time point, where T is the number of slots corresponding to a duration, and T is a positive integer. In this case, T is less than or equal to the number of slots in the duration. In this way, the terminal device may need to monitor the PDCCH in the first T slots within the 1st duration that is after the first time point, which is conducive to reliability of PDCCH monitoring and flexibility of control by a base station (the value of T may be set).
Exemplarily, as illustrated in

Monitor a PDCCH in first K slots that are after the first time point, where K is a positive integer. In this way, the terminal device may need to monitor the PDCCH in the first K slots that are after the first time point, which is conducive to reliability of PDCCH monitoring and flexibility of control by a base station (the value of K may be set).
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in first H slots that are after the first time point if no duration is configured, where H is a positive integer. In this way, if no duration is configured, the terminal device may need to monitor the PDCCH in the first H slots that are after the first time point, which is conducive to reliability of PDCCH monitoring and flexibility of control by a base station (the value of H may be set).
Exemplarily, as illustrated in
The duration represents a duration of a PDCCH, or a duration of a PDCCH monitoring occasion, or a duration of an SSS for a PDCCH, or a slot-level duration of an SSS for a PDCCH. Each duration includes one or more slots, and a PDCCH in each slot occupies one or more symbols. The network device may configure for the terminal device a duration corresponding to an SSS for the terminal device via a higher-layer parameter (duration) in the SSS, that is, the duration may be a parameter in the SSS.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH within first X durations that are after the first time point, where X is a positive integer. In this way, the terminal device may need to monitor the PDCCH within the first X durations that are after the first time point (the number of slots therein is the number of slots in one duration multiplied by X), which is conducive to reliability of PDCCH monitoring.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in first X PDCCH periods that are after the first time point, where X is a positive integer. In this way, the terminal device may need to monitor the PDCCH in the first X PDCCH periods that are after the first time point (the number of slots therein is the number of slots in one duration multiplied by X), which is conducive to reliability of PDCCH monitoring.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in W slots within first X durations that are after the first time point, where X and Weach are a positive integer, and W is less than or equal to the number of slots in one duration multiplied by X. In this way, the terminal device may need to monitor a PDCCH(s) in multiple slots within the first X durations that are after the first time point, thereby improving reliability of PDCCH monitoring.
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in W slots within first X PDCCH periods that are after the first time point, where X and W each are a positive integer, and W is less than or equal to the number of slots in one duration multiplied by X. In this way, the terminal device may need to monitor a PDCCH(s) in multiple slots within the first X PDCCH periods that are after the first time point, thereby improving reliability of PDCCH monitoring.
Exemplarily, as illustrated in
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in first P PDCCH periods that are after the first time point, where P is a positive integer. In this way, the terminal device may need to monitor the PDCCH in the first P PDCCH periods that are after the first time point, which improves reliability of PDCCH monitoring and improves flexibility of control by a base station (the value of P may be set).
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH in first F PDCCH periods that are after the first time point if no duration is configured, where F is a positive integer. In this way, the terminal device may need to monitor the PDCCH in the first F PDCCH periods that are after the first time point, which improves reliability of PDCCH monitoring and improves flexibility of control by a base station (the value of F may be set).
Exemplarily, as illustrated in
In a possible implementation, the terminal device monitors the PDCCH after the first time point as follows. Monitor a PDCCH within a time window that is after the first time point. The time window is a fixed time range configured for the terminal device.
Exemplarily, as illustrated in
In a possible implementation, the first time point equals to a predefined time point (exemplarily, may be referred to as a second time point) plus a first time interval. i.e.:
In other words, the first time interval is a time interval between the first time point and the predefined time point. Since the low-power receiver triggers turn-on of the overall receiver after the wake-up signal is detected by the low-power receiver at the predefined time point and a time interval is needed to turn on the overall receiver, the first time point equals to the predefined time point plus the first time interval, which ensures that the time interval for turning on the overall receiver is long enough, and the overall receiver has enough time to be turned on.
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a second time interval. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. Since the low-power receiver triggers turn-on of the overall receiver after the wake-up signal is detected by the low-power receiver at the predefined time point and a time interval is needed to turn on the overall receiver, the time for such procedure is included in the second time interval. The terminal device needs to have a capability of turning on the overall receiver within the second time interval, where the capability may be agreed between the network device and the terminal device. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a time interval related to an SSB period or an SS burst period. The SSB period or the SS burst period may refer to a period of a half frame (5 milliseconds (ms) in length) used for transmitting an SSB or an SS burst. In this way, one or more SSBs or SS bursts can be processed by the overall receiver after the overall receiver is turned on, so as to realize time-frequency synchronization and/or measurement. i.e.:
Exemplarily, as illustrated in
Optionally, the first time interval includes Z SSB periods or SSB burst periods, where Z is a positive integer. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a second time interval plus a time interval related to an SSB period or an SS burst period. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a second time interval plus Y SSB periods, where Y is a positive integer. Alternatively, the first time interval includes a second time interval plus R SSB burst periods, where R is a positive integer. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. In this way, one or more SSBs or SS burst periods can be processed by the overall receiver after the overall receiver is turned on, so as to realize time-frequency synchronization and/or measurement.
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes an interval between a reference time point and a slot in which M SSBs or SS bursts closest to the reference time point (exemplarily, may be referred to as a third time point) are located, where M is a positive integer. The reference time point equals to the predefined time point plus a second time interval. The M SSBs or SS bursts closest to the reference time point may be first M SSBs or SS bursts after the reference time point. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. In this way, it is possible to ensure that there is a reference time point after the overall receiver is turned on.
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes A SSB periods and B tracking reference signal periods, where A and Beach are a positive integer. In this way, the network device can send a tracking reference signal after sending the wake-up signal, so as to facilitate time-frequency synchronization and/or measurement of the overall receiver. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a second time interval plus C SSB periods and D tracking reference signal periods, where C and D each are a positive integer. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. i.e.:
Exemplarily, as illustrated in
For another example, as illustrated in
In a possible implementation, the first time interval includes an interval between a reference time point and a slot in which E SSBs and F tracking reference signals closest to the reference time point are located, where E and F each are a positive integer, and the reference time point equals to a predefined time point plus a second time interval. The E SSBs and the F tracking reference signals closest to the reference time point may be first E SSBs and F tracking reference signals after the reference time point. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. In this way, with such reference time point, it is possible to ensure that there is a reference time point after the overall receiver is turned on. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a period of a preamble sequence. In this way, the network device can send a preamble after sending the wake-up signal, so as to facilitate time-frequency synchronization and/or measurement of the overall receiver. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes a second time interval plus a period of a preamble sequence. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. The preamble sequence is a special signal in a frame structure, is characterized by short time, and can facilitate quick time-frequency synchronization and/or measurement of the overall receiver. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the first time interval includes an interval between a reference time point and a slot in which a preamble sequence closest to the reference time point is located, where the reference time point equals to a predefined time point and a second time interval. The second time interval may be pre-defined in a protocol, or may be configured by the network device, or may be determined by the terminal device based on some policy or algorithm. In this way, with such reference time point, it is possible to ensure that there is a reference time point after the overall receiver is turned on. i.e.:
Exemplarily, as illustrated in
In a possible implementation, the second time interval is zero. That is, in the possible manner described above, there may be no second time interval included in the first time interval.
In a possible implementation, the predefined time point is a position in a sequence of the wake-up signal. Optionally, the predefined time point is an ending position of the sequence of the wake-up signal. In this way, it is possible to ensure that there is a reference time point for the terminal device and the network device.
In a possible implementation, the second time interval is determined based on a capability of the terminal device. Since the time for a procedure in which the low-power receiver triggers turn-on of the overall receiver depends on the capability of the terminal device, the second time interval may be determined based on the capability of the terminal device.
In a possible implementation, the first time interval is configured via higher-layer signaling. Optionally, the higher-layer signaling includes system information block (SIB) signaling or non-access stratum (NAS) signaling. In this way, a time interval can be configured flexibly via higher-layer signaling, where the time interval includes (is greater than or equal to) a pre-defined time interval. It should be noted that, the network device may configure the first time interval via SIB signaling (broadcast mode), or the network device may configure the first time interval via NAS signaling (unicast mode or dedicated pilot mode).

Referring to
2001, a terminal device receives a wake-up signal, where the wake-up signal includes UE group information.
2002, the terminal device determines, based on the wake-up signal, whether the terminal device is woken up.
In embodiments of the disclosure, the wake-up signal includes the UE group information (i.e. information of a UE group), that is, a sequence of the wake-up signal includes the UE group information. Therefore, by detecting the wake-up signal, the terminal device may determine whether a UE group corresponding to a paging occasion (PO) is waken up, thereby reducing unnecessary power consumption of the terminal device. In addition, since sequences of different random signals may be differentiated based on generators of the sequences of the random signals, the UE group information may also be contained in a generator of the sequence of the wake-up signal. Optionally, the terminal device receives the wake-up signal sent by a network device, where the network device may determine the UE group information based on a higher-layer parameter of a PO.
In a possible implementation, the UE group information includes a UE group identity (ID). The UE group ID is implied in a PO. The PO may be defined as a position in a paging frame (PF), where a system frame number of the PF depends on a first higher-layer parameter, and a position (index) of the PO in the PF depends on a second higher-layer parameter. Therefore, the UE may determine, according to the first higher-layer parameter and the second higher-layer parameter, the system frame number of the PF in which the PO is located and the position (index) of the PO in the PF. In other words, based on the UE group ID, the first higher-layer parameter, and the second higher-layer parameter, the network device and the terminal device may agree on a time (namely, a PO) at which the network device sends a paging message and the terminal device receives the paging message, and the paging message sent by the network device at the PO is specific to a UE group corresponding to the PO. Therefore, the UE group information may be the UE group ID, and similar to the above manner for determining the PO, the UE group ID is obtained according to a UE ID and a higher-layer parameter.
In a possible implementation, the UE group ID is calculated based on the UE ID, the first higher-layer parameter, and the second higher-layer parameter.
In a possible implementation the UE group ID includes a first ID and a second ID. Optionally, the first ID is calculated based on the UE ID and the first higher-layer parameter, and the second ID is calculated based on the UE ID and the second higher-layer parameter. In this way, it is possible to ensure that the UE group is equivalent to a UE group corresponding to a PO.
Optionally, the first ID is a remainder obtained by dividing the UE ID by the first higher-layer parameter, and the second ID is a remainder obtained by dividing the UE ID by the second higher-layer parameter.
Optionally, the UE group ID is a remainder obtained by dividing the UE ID by a target parameter, where the target parameter is a product of the first higher-layer parameter and the second higher-layer parameter.
Optionally, the first higher-layer parameter is a higher-layer parameter that is related to UE subgrouping and used for calculating a PF. The second higher-layer parameter is a higher-layer parameter that is related to UE subgrouping and used for calculating a PO.
