Correspondingly, a terminal device receives the WUS.
In some embodiments, the wake up signal may be received by the terminal device through a wake up receiver (WUP) (also referred to as a low-power receiver).
It should be understood that the present application does not limit the specific implementation of the wake up receiver. For example, as shown in
Specifically, as shown in
Specifically, as shown in
In some embodiments, the main receiver may have strong information processing capabilities, such as supporting large bandwidth (e.g., 100 MHz) and high-speed (e.g., 1 Gbps) information reception and processing, and high-complexity waveform detection. For example, the main receiver may be an LTE terminal receiver, an NR terminal receiver, or other terminal receivers in future standard evolution.
In some embodiments, the wake up receiver may have relatively low information processing capabilities, such as only supporting narrow bandwidth and low-speed information reception and processing, and low-complexity waveform detection.
In some embodiments, the description that the wake up signal is used to wake up the terminal device may mean that the wake up signal is used to wake up the main receiver of the terminal device.
That is to say, the main receiver may be activated based on the wake up signal, which is beneficial to reducing the power consumption of the terminal device.
In some embodiments, the terminal device wakes up the main receiver to listen PDCCH or a paging message.
In some embodiments, the target sequence may be used for identifying the wake up signal, and/or synchronizing, and/or carrying the wake up information.
For example, the target sequence may include a preamble sequence for identifying the wake up signal or a synchronization sequence for synchronizing, and/or a sequence for carrying the wake up information, which is denoted as a wake up information sequence.
It should be understood that, in the embodiments of the present application, the preamble sequence may also be used for synchronizing, and the synchronization sequence may also be used as the preamble sequence.
In some embodiments of the present application, the wake up signal may be generated using a low-complexity modulation method. For example, the wake up signal is generated using on-off keying (OOK) modulation, e.g., multi-carrier OOK modulation. For another example, the wake up signal is generated using amplitude shift keying (ASK) modulation, e.g., multi-carrier ASK modulation. The modulation principle of the OOK is to modulate an amplitude of a carrier signal to a non-zero value and zero value, which correspond to On and Off respectively, for representing information bits. The OOK modulation is also known as 2 amplitude shift keying (2ASK). As shown in
In some embodiments, a downlink signal is generated using a high-complexity modulation method, e.g., an orthogonal frequency division multiplexing (OFDM) modulation. As an implementation, the network device may obtain the wake up signal by performing the OOK modulation or ASK modulation on multiple subcarriers of an OFDM signal.
That is to say, the wake up signal in the embodiments of the present application may adopt a simple modulation waveform, which is beneficial to reducing the complexity of the wake up receiver detecting the wake up signal.
In some embodiments, the wake up signal includes the wake up information, and the wake up information may be carried through a sequence, or may be carried in other ways. For example, the wake up signal directly includes the wake up information itself, or may include information bits obtained by encoding the wake up information. The present application is not limited thereto.
The carrying method of the wake up information will be described below in combination with specific embodiments.
In Embodiment 1, the wake up information is carried through the sequence.
In Embodiment 1-1, the target sequence includes a first sequence and a second sequence, the first sequence is a preamble sequence or a synchronization sequence, and the second sequence is used to carry the wake up information. That is, the second sequence is a wake up information sequence.
In Embodiment 1-2, the target sequence includes a second sequence, and the second sequence is used to carry the wake up information.
For example, as shown in
That is to say, the wake up information sequence may be used alone as the wake up signal, or may be used together with the preamble sequence or the synchronization sequence as the wake up signal.
In some embodiments, when the terminal device receives the wake up signal including the wake up information sequence, it may be determined that the wake up information is received. Furthermore, the terminal device may wake up the main receiver.
It should be understood that the number of bits of the wake up information is not limited in the present application. For example, the wake up information carried in the wake up signal may contain at least 1 bit of information. By carrying the 1-bit information through the second sequence, the terminal device may perform correlation detection on the second sequence and receive the wake up information more reliably.
In some embodiments, the wake up information carried in the second sequence may be used to wake up one terminal device, or may be used to wake up a plurality of terminal devices, e.g., all terminal devices in a single terminal group.
In some embodiments, the second sequence (i.e., wake up information sequence) is obtained by scrambling a third sequence (also referred to as a feature sequence) using identity (ID) information of the terminal device or ID information of the terminal group.
That is to say, an actual transmitted sequence may be obtained by scrambling the feature sequence using the ID information of the terminal device (e.g., UE ID) or the ID information of the terminal group. That is, the second sequence is carried in the wake up signal to be transmitted. In this way, the terminal device may determine whether the wake up signal is transmitted to itself based on the ID information of the scrambled feature sequence.
In some embodiments, the identity (ID) information of the terminal device may be radio network temporary identity (RNTI) information of the terminal device. For example, for a terminal device in the connected state, the RNTI may be a cell radio network temporary identity (C-RNTI).
In some embodiments, the feature sequence includes M bits, the UE ID includes N bits, and M>N. Any N bits in the M bits are scrambled using the UE ID to obtain an actual transmitted sequence that occupies M bits.
In some embodiments, the wake up information sequence may be generated through the following method that:
That is, the last 16 bits of the 32-bit sequence 1 are scrambled using 16-bit RNTI to obtain a new 32-bit sequence 2, which is used as the actual transmitted sequence, i.e., sequence 2.
In some embodiments, the third sequence is predefined, or configured by the network device, or determined according to a preset rule. That is to say, the terminal device and the network device have a consistent understanding of the third sequence.
Optionally, in a case where the terminal device is in the connected state, the third sequence may be configured by the network device, for example, may be configured through a radio resource control (RRC) signaling or system information. Optionally, in a case where the terminal device is in an idle state or an inactive state, the third sequence may be determined according to the preset rule.
In some embodiments, the third sequence is determined by the terminal device from a first candidate sequence set.
In some embodiments, the first candidate sequence set includes at least one candidate third sequence.
Optionally, each candidate third sequence in the first candidate sequence set corresponds to one number or an index. For example, the first candidate sequence set includes 8 candidate third sequences, and the corresponding numbers or indexes may be 0 to 7 or 1 to 8, respectively.
In some embodiments, the third sequence is determined from the first candidate sequence set according to the ID information of the terminal device.
For example, a feature sequence corresponding to the UE may be calculated according to the UE ID. As an example, a result obtained by taking the modulus of the number of sequences in the first candidate sequence set through the UE ID is used to determine a target third sequence. For example, the obtained result may be the number or index of the target third sequence in the first candidate sequence set. The method is advantageous for distributing the feature sequences corresponding to different terminal devices to the feature sequences in the first candidate sequence set in a relatively even manner.
In some embodiments, the first candidate sequence set is configured by the network device, or is predefined. For example, the first candidate sequence set may be configured through the RRC signaling or system information.
In some embodiments, different terminal devices correspond to different third sequences.
In some embodiments, different terminal groups correspond to different third sequences.
That is, the third sequence is configured for each terminal device, or the third sequence is configured for each terminal group.
In other words, different terminal devices or terminal groups may be distinguished according to the third sequences.
For example, the network device may configure different third sequences for different terminal devices.
For another example, the network device may configure different third sequences for different terminal groups. Each terminal group uses the same third sequence, and different second sequences are formed by scrambling different UE IDs in the third sequence, and correspond to the wake up information of different terminal devices.
In some other embodiments, different terminal devices correspond to the same third sequence. In this case, the third sequence may be scrambled using the ID information of different terminal devices to obtain different second sequences for distinguishing different terminal devices, or different terminal devices may be distinguished by different preamble sequences or synchronization sequences.
In some other embodiments, different terminal groups correspond to the same third sequence. In this case, the third sequence may be scrambled using the ID information of different terminal groups to obtain different second sequences for distinguishing different terminal groups, or different terminal groups may be distinguished by different preamble sequences or synchronization sequences.
In some embodiments, the third sequences adopted by different terminal devices or terminal groups are generated based on different sequences, or the third sequences adopted by different terminals or terminal groups are generated based on different cyclic shifts (CSs) of the same sequence.
In some embodiments, the first sequence is predefined, or configured by the network device, or determined according to a preset rule. That is to say, the terminal device and the network device have a consistent understanding of the first sequence.
Optionally, in a case where the terminal device is in the connected state, the first sequence may be configured by the network device, for example, by the RRC signaling or system information. Optionally, in a case where the terminal device is in the idle state or the inactive state, the first sequence may be determined according to the preset rule.
For example, the first sequence may adopt a predefined sequence W containing 32 bits, and
In some embodiments, different first sequences may be adopted by different terminal devices or terminal groups.
For example, the first sequences adopted by the different terminal devices or terminal groups are generated based on different sequences, or the first sequences adopted by different terminals or terminal groups are generated based on different cyclic shifts of the same sequence.
In some other embodiments, the same first sequence may be adopted by different terminal devices or terminal groups. Furthermore, different terminal devices or different terminal groups may be distinguished by second sequences.
In some embodiments, the first sequence is determined by the terminal device from a second candidate sequence set.
In some embodiments, the second candidate sequence set includes at least one candidate first sequence.
Optionally, each candidate first sequence in the second candidate sequence set corresponds to one number or index. For example, the second candidate sequence set includes 8 candidate first sequences, and the corresponding numbers or indexes may be 0 to 7 or 1 to 8, respectively.
In some embodiments, the first sequence is determined from the second candidate sequence set according to the ID information of the terminal device.
For example, the first sequence corresponding to the UE is calculated according to the UE ID. As an example, a result obtained by taking the modulus of the number of sequences in the second candidate sequence set through the UE ID is used to determine a target first sequence. For example, the obtained result may be the number or index of the target first sequence in the second candidate sequence set. This method is advantageous for distributing the first sequences corresponding to different terminal devices to the first sequences in the second candidate sequence set in a relatively even manner.
In some embodiments, the second candidate sequence set is configured by the network device, or is predefined. For example, the second candidate sequence set may be configured through the RRC signaling or system information.
In summary, for Embodiment 1-1, different terminal devices or terminal groups may be distinguished based on the first sequences and/or the second sequences.
For example, different terminal devices or terminal groups correspond to different preamble sequences or synchronization sequences.
For another example, the different terminal devices or terminal groups correspond to different wake up information sequences.
For Embodiment 1-2, different terminal devices or terminal groups may be distinguished based on the second sequences.
In some embodiments, different wake up information sequences corresponding to different terminal devices or terminal groups may be implemented through the following methods (applicable to Embodiment 1-1 and Embodiment 1-2) that:
In Embodiment 2, the wake up signal includes the wake up information. In other words, the wake up signal includes explicit wake up information.
In some embodiments, the wake up signal may include the wake up information itself, or may include information bits obtained by encoding the wake up information. By carrying the wake up information in this manner, it is beneficial to improve the transmission reliability. Optionally, the encoding method may include, but is not limited to, reverse non-return-to-zero (NRZ) encoding, Manchester encoding, unipolar return-to-zero encoding, differential bi-phase (DBP) encoding, differential encoding, pulse interval encoding (PIE), bidirectional space encoding (FM0), Miller encoding differential encoding.
For example, in the Manchester encoding, if the wake up information is 0, it is coded as 10; or if the wake up information is 1, it is coded as 01. In this case, the wake up signal carries the encoded wake up information.
The description is made below by taking an example where the wake up information in the wake up signal is the wake up information before encoding, but the present application is not limited thereto.
In some embodiments, the target sequence includes the first sequence that is the preamble sequence or the synchronization sequence; and the wake up signal further includes target wake up information, and the target wake up information includes wake up information of at least one terminal device, or wake up information of at least one terminal group, or wake up information of at least one terminal subgroup in a single terminal group.
In some embodiments, the single terminal group may include a plurality of terminal subgroups, and a single terminal subgroup may include one or more terminal devices.
That is, the wake up signal may indicate wake up information at the granularity of the terminal device, wake up information at the granularity of the terminal group, or wake up information at the granularity of the terminal subgroup.
As shown in
In some embodiments, whether to wake up the at least one terminal device or the at least one terminal group or the at least one terminal subgroup may be indicated in a bitmap manner.
For example, the target wake up information includes a plurality of bit groups, each bit group corresponds to one terminal device or one terminal group or one terminal subgroup, a value of each bit group is used to indicate whether to wake up the corresponding terminal device or terminal group or terminal subgroup, and each bit group includes one or more bits.

As shown in
In some embodiments, the wake up signal further includes check bit information for checking the target wake up information.
For example, the wake up signal may further include cyclical redundancy check (CRC) information, the CRC information is obtained by performing CRC calculation on the target wake up information. By setting the CRC information and the target wake up information in the wake up signal and transmitting them together, the terminal device that receives the wake up signal may perform a CRC check on the target wake up information based on the CRC information to determine whether the received target wake up information is correct.
In some embodiments, a bit location occupied by the wake up information of each terminal device in the at least one terminal device in the target wake up information is configured by the network device, or determined according to a preset rule. That is, the terminal device and the network device have a consistent understanding of the bit location occupied by the wake up information of the terminal device in the target wake up information.
For example, a correspondence between the wake up information of each terminal device and the one or more bits may be configured by the network device, or determined according to the preset rule.
Optionally, the correspondence between the wake up information of each terminal device and the one or more bits may be configured through the RRC signaling or system information.
For another example, a bit location occupied by the wake up information of the at least one terminal device in a target wake up signal is determined according to the ID information of the at least one terminal device.
As an example, a result obtained by taking the modulus of the number of bits (or the number of bit groups) contained in the target wake up information carried in the wake up signal through the UE ID is used to determine the bit location of the wake up information corresponding to the UE in the target wake up information carried in the wake up signal. For example, the obtained result may be used to represent a bit number or index occupied by the wake up information corresponding to the UE in the target wake up information. In this way, the wake up information corresponding to different terminal devices is distributed relatively evenly to bits of the wake up information carried in the wake up signal.

For another example, the bit location occupied by the wake up information corresponding to each terminal subgroup in the target wake up information may be determined according to the number or index of the terminal subgroup in the terminal group.
For example, a terminal group includes 12 terminal subgroups numbered 0 to 11; and in a case where the target wake up information includes 12 bits (B0 to B11), B0 to B11 correspond to the terminal subgroups numbered 0 to 11, respectively.
Optionally, in Embodiment 2, the first sequence is predefined, or configured by the network device, or determined according to the preset rule. For example, the first sequence may be configured through the RRC signaling or system information.

In Embodiment 4, different terminal devices or terminal groups are distinguished by transmission resources.
In some embodiments, transmission resources of wake up signals corresponding to different terminal devices are different.
That is to say, the wake up signals for different terminal devices may be transmitted using different transmission resources.
In some embodiments, transmission resources of wake up signals corresponding to different terminal groups are different.
That is to say, the wake up signals for different terminal groups may be transmitted using different transmission resources.
Correspondingly, for different terminal devices or terminal devices belonging to different terminal groups, the wake up signals may be detected on the respective transmission resources.
In some embodiments, the transmission resource may refer to any transmission resource of a signal, for example, may include a time domain resource and/or a frequency domain resources, or may include any other transmission resource, such as a code domain resource.
For example, frequency domain resources of the wake up signals corresponding to different terminal devices or terminal groups are different.
For another example, time-frequency resources of the wake up signals corresponding to different terminal devices or terminal groups are different.
In some embodiments, the transmission resources of the wake up signals corresponding to different terminal devices are configured by the network device, or determined according to a preset rule. For example, the transmission resources may be configured through the RRC signaling or system information. In other words, the terminal device and the network device have a consistent understanding of a location of the transmission resource corresponding to the wake up signal.
In some embodiments, the transmission resources of the wake up signals corresponding to different terminal groups are configured by the network device, or determined according to a preset rule. For example, the transmission resources may be configured through the RRC signaling or system information. In other words, the terminal device and the network device have a consistent understanding of the location of the transmission resource corresponding to the wake up signal.
By taking an example where the transmission resource is the frequency domain resource, the wake up signals of different terminal devices or terminal groups may be configured to correspond to different frequency domain resources. Accordingly, the different terminal devices or terminal groups detect the wake up signals on the different frequency domain resources to obtain the wake up information. As shown in
By taking an example where the transmission resource is the time-frequency resource, the wake up signals of different terminal devices or terminal groups may be configured to correspond to different time-frequency resources. Accordingly, the different terminal devices or terminal groups detect the wake up signals on the different time-frequency resources to obtain the wake up information. As shown in
It should be understood that, in the embodiments of the present application, the wake up information of different terminal devices or terminal groups may be distinguished only by the transmission resources, or the wake up information of different terminal devices or terminal groups may be distinguished only by sequences (such as preamble sequences, synchronization sequences, or feature sequences), or the wake up information of different terminal devices or terminal groups may be distinguished by transmission resources and sequences.
For example, the wake up signals corresponding to different terminal devices or terminal groups are distinguished through two dimensions: frequency domain resources and feature sequences. For example, on the same frequency domain resource, wake up signals transmitted using different third sequences or first sequences correspond to different terminal devices or terminal groups. Optionally, the third sequence may be the third sequence in Embodiment 1, and the first sequence may be the first sequence in Embodiment 2.
For another example, the wake up signals corresponding to different terminal devices or terminal groups are distinguished through three dimensions: time domain resources, frequency domain resources, and feature sequences. For example, on the same time-frequency resource, wake up signals transmitted using different third sequences or first sequences correspond to different terminal devices or terminal groups. Optionally, the third sequence may be the third sequence in Embodiment 1, and the first sequence may be the first sequence in Embodiment 2.
In some embodiments, if the transmission resource of the wake up signal is for the terminal device or the terminal group, the wake up signal may not include the ID information of the terminal device or the ID information of the terminal group. In a case where the terminal device receives the wake up signal on the corresponding transmission resource, it may be determined that the wake up signal contains its own wake up information. Furthermore, the terminal device may wake up the main receiver according to the wake up information.
Based on Embodiments 1 to 4, different terminal devices or terminal groups may be distinguished by the transmission resources of the wake up signals, and/or different terminal devices or terminal groups may be distinguished by different third sequences or first sequences.
Optionally, in a case where the terminal devices are in the connected state, the transmission resources of the wake up signals corresponding to different terminal devices may be configured by the network device, for example, may be configured through the RRC signaling or system information. Optionally, in a case where the terminal devices are in the idle state or the inactive state, the transmission resources of the wake up signals corresponding to different terminal devices may be determined according to a preset rule.
Optionally, in a case where the terminal devices are in the connected state, the transmission resources of the wake up signals corresponding to different terminal groups may be configured by the network device, for example, may be configured through the RRC signaling or system information. Optionally, in a case where the terminal devices are in the idle state or the inactive state, the transmission resources of the wake up signals corresponding to different terminal groups may be determined according to a preset rule.
In some embodiments, the transmission resource of the wake up signal corresponding to the terminal device is determined from a candidate wake up signal transmission resource set according to a preset rule.
In some embodiments, the candidate wake up signal transmission resource set may include at least one candidate wake up signal transmission resource.
Optionally, each candidate wake up signal transmission resource in the candidate wake up signal transmission resource set corresponds to one number or index. For example, the candidate wake up signal transmission resource set includes 8 candidate wake up signal transmission resources, and the corresponding numbers or indexes may be 0 to 7 or 1 to 8, respectively.
In some embodiments, the transmission resources of the wake up signals corresponding to different terminal devices are determined according to the ID information of the terminal devices.
For example, the result obtained by taking the modulus of the number of transmission resources in the candidate wake up signal transmission resource set through the UE ID is used to determine the location of a target transmission resource. For example, the obtained result may be the number or index of the target transmission resource in the candidate wake up signal transmission resource set. In this way, the transmission resources of the wake up signals corresponding to different terminal devices may be distributed relatively evenly to the transmission resources in the candidate wake up signal transmission resource set.
It should be understood that, the transmission resource of the wake up signal corresponding to the terminal group may be determined in a similar manner as the above, which will not be repeated here for the sake of brevity.
In some embodiments, the candidate wake up signal transmission resource set is configured by the network device, or is predefined. For example, the candidate wake up signal transmission resource set may be configured through the RRC signaling or system information.
Optionally, in some embodiments, the transmission resource for transmitting the wake up signal may be a dedicated transmission resource. That is, the terminal device may determine that a received signal is the wake up signal based on the transmission resource. In this case, optionally, the wake up signal may not include the preamble sequence for identifying the wake up signal.
It should be understood that, Embodiment 4 may be implemented alone, or may be implemented in combination with any one of Embodiments 1 to 3, and the present application does not limit these.
In some embodiments, Embodiment 4 may be implemented in combination with Embodiment 2. For example, in Embodiment 4, the transmission resources of the wake up signals corresponding to different terminal groups are different. That is, the terminal group corresponding to the wake up signal may be determined by the transmission resource. Furthermore, in Embodiment 2, different bits in the target wake up information in the wake up signal may correspond to different terminal devices or terminal subgroups, and the wake up information corresponding to different terminal devices or different terminal subgroups in the terminal group may be determined based on the target wake up information.
In some embodiments, Embodiment 4 may also be implemented in combination with Embodiment 3. For example, in Embodiment 4, the transmission resources of the wake up signals corresponding to different terminal groups are different. That is, the terminal group corresponding to the wake up signal may be determined by the transmission resource. Furthermore, in Embodiment 3, the wake up signal may include the identity information of the terminal device or terminal subgroup in the terminal group, which indicates the terminal device or terminal subgroup to be woken up in the terminal group.
In summary, in the embodiments of the present application, the network device may transmit the wake up signal to the terminal device, the wake up signal includes the target sequence, and the target sequence is used for identifying the wake up signal and/or synchronizing and/or carrying the wake up information. Furthermore, the terminal device may wake up the main receiver with relatively high power consumption based on the wake up signal to receive signals, which is beneficial to reducing the power consumption of the terminal device.
In some implementations, the wake up information may be carried by the sequence. In this case, the wake up signal may include the preamble sequence or the synchronization sequence, or may not include the preamble sequence or the synchronization sequence.
In some implementations, the wake up signal includes the preamble sequence or the synchronization sequence, and the target wake up information, and the target wake up information may include wake up information of a plurality of terminal devices or a plurality of terminal groups.

In some embodiments, different terminal devices or terminal groups may be distinguished by different preamble sequences or synchronization sequences, or different terminal devices or terminal groups may be distinguished by different feature sequences, or different terminal devices or terminal groups may be distinguished by scrambling the feature sequence using the ID information of the terminal devices or the ID information of the terminal groups.
