Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication processing method and a communication device. Background Art

[0002] With the development of wireless communication technologies, there are higher requirements for device power consumption. In addition to latency, reliability, and availability, the energy efficiency of user equipment (UE) is also crucial in 5G systems. Currently, 5G devices may need to be charged weekly or daily according to an individual's usage time. Generally, 5G devices consume tens of milliwatts of power when in the radio resource control (RRC) idle or inactive state, and hundreds of milliwatts of power when in the RRC connected state. How to extend the battery life is a necessary condition for improving energy efficiency and user experience.

[0003] To improve the battery life, the current art has introduced a low power wakeup signal (LP-WUS) mechanism, that is, the user uses a separate low power wakeup receiver (LP-WUR) to receive the low power wakeup signal, and wakes up the main radio (MR) through the wakeup signal for data transmission and data reception. When the UE does not detect the low power wakeup signal, the main receiver is in a deep sleep state, and the power consumption of the terminal is further reduced in this way.

For downlink signal transmission, the transmitting device is network device 110, and the corresponding receiving device is terminal device 120. For uplink signal transmission, the transmitting device is terminal device 120, and the corresponding receiving device is network device 110.

[0062] In embodiments of the present application, a time-domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol or a discrete Fourier transform-spread OFDM (DFT-s-OFDM) symbol. Unless otherwise specified, the symbols in embodiments of the present application refer to time-domain symbols.

[0063] It can be understood that in embodiments of the present application, the physical downlink shared channel (PDSCH), the physical downlink control channel (PDCCH), and the physical uplink shared channel (PUSCH) are only examples of a downlink data channel, a downlink control channel, and an uplink data channel respectively. In different systems and different scenarios, data channels and control channels may have different names, and embodiments of the present application do not limit this.

[0064] In an embodiment of the present application, a low-power wakeup signal (LP-WUS) is introduced in the communication standard. This LP-WUS is received using a separate receiver, which is called a low-power wakeup receiver (LP-WUR) 121. The terminal device 120 needs to use the main radio (MR) 122 to normally process downlink and / or uplink data.

[0065] In a possible implementation, when the LP-WUR 121 of the terminal device 120 receives the LP-WUS and the LP-WUS indicates wakeup, the terminal device 120 will turn on the MR 122 to receive and process downlink and / or uplink signals.

[0066] In a possible implementation, if the LP-WUR 121 of the terminal device 120 does not receive the LP-WUS signal, or the LP-WUS received by the LP-WUR 121 of the terminal device 120 indicates not to wake up, the terminal device 120 will keep the MR 122 in the sleep state.

[0067] Optionally, the LP-WUS signal can be used in states such as radio resource control (RRC) connected, inactive, idle, etc.

[0068] In a possible implementation, the sleep state of the MR 122 can include four types: ultra-deep sleep, deep sleep, light sleep, and microsleep.

[0069] To ensure that the power consumption of the LP-WUR 121 is relatively low when it is in the ON state, optionally, the LP-WUR 121 can use envelope detection to determine the information carried by the received LP-WUS signal.

[0070] In a possible implementation, envelope detection includes amplitude detection or energy detection, that is, the terminal device determines the specific information carried by the LP-WUS signal by detecting the amplitude or energy level of the LP-WUS sent by the network device. Optionally, multi-carrier on-off keying (MC-OOK) modulation, frequency-shift keying (FSK) modulation, and amplitude-shift keying (ASK) modulation can be candidate modulation methods for LP-WUS.

[0071] In a possible implementation, LP-WUS can be designed based on orthogonal frequency division multiplexing (OFDM) to achieve a better signal coverage range. At this time, the LP-WUR 121 can have a certain decoding ability and can receive and decode OFDM-based wireless signals. The power consumption of the OFDM-based LP-WUR 121 in the ON state is lower than that of the MR, but higher than that of the envelope detection-based LP-WUR 121.

[0072] In a possible implementation, the operating mode (detection mode) of the LP-WUR 121 can include the following two types:

[0073] Continuous monitoring mode, that is, the LP-WUR 121 is always in the ON state. In this embodiment, the continuous detection method can effectively reduce the delay.

[0074] Duty cycle mode, that is, the LP-WUR 121 is in the ON state during certain time periods and in the OFF state during other time periods. In this embodiment, duty cycle detection can further reduce the power consumption of the LP-WUR 121.

[0075] In a possible implementation, the network device 110 can wake up the terminal devices 120 in the cell that support LP-WUS or change the sleep states of these terminal devices 120 by sending LP-WUS. For the terminal devices 120 that support LP-WUS, at least one LP-WUS signal is received through the LP-WUR 121, and the wake-up or sleep state change of the MR 122 is completed according to the information carried by the received LP-WUS signal.

[0076] Optionally, the change in the sleep state of MR 122 refers to the mutual switching among states such as ultra-deep sleep, deep sleep, light sleep, and micro sleep, and the wake-up of MR 122 refers to the conversion of MR 122 from any sleep state to the wake-up state.

[0077] In one possible implementation, the design methods of LP-WUS may include the following two:

[0078] Optionally, the LP-WUS based on constant envelope may have obvious energy-saving advantages.

[0079] Optionally, the LP-WUS based on OFDM may have a higher coverage range, support more functions, and have higher reliability.

[0080] In one possible implementation, two or more working modes of LP-WUR 121 are supported by both the network device 110 and the terminal device 120. Optionally, the network device 110 needs to determine the capabilities of the LP-WUR121 of the terminal device 120 in the cell, so as to send LP-WUS to the terminal device 120 in a suitable manner.

[0081] In one possible implementation, by the terminal device 120 reporting the terminal device capabilities, the network device 110 can understand the form of LP-WUS that the terminal device 120 can receive. The terminal device capabilities can be described from the perspective of the LP-WUS detection mode or from the perspective of the capabilities of LP-WUR 121. Optionally, if the terminal device capabilities of the terminal device 120 are not reported, they are determined according to certain default principles or by the network device 110.

[0082] Figure 2 The flowchart of a communication processing method provided by an embodiment of the present application is shown. Figure 2 The execution subject of the shown method may be the above-mentioned terminal device and network device. Or, Figure 2 The execution subject of the shown method may be the chips in the terminal device and the chips in the network device, which is not limited in the embodiments of the present application. Figure 2 Taking the terminal device and the network device as the execution subjects of the method as an example for illustration.

[0083] S201. The network device sends the first information to the terminal device.

[0084] Wherein, the first information is used to instruct the terminal device to determine the detection mode for the target signal based on the first information, and wherein the detection mode includes a continuous detection mode or a periodic detection mode.

[0085] In a possible implementation, the terminal device can support two or more detection modes for the target signal. For example, the detection modes can include a continuous detection mode and / or a periodic detection mode. Corresponding to the signal detection modes supported by the terminal device, the network device can correspondingly support two or more transmission modes for the target signal.

[0086] The network device can send first information to the terminal device according to service requirements to indicate that the terminal device adopts a suitable detection mode to detect the target signal.

[0087] For example, when the service requires low latency, the network device can instruct the terminal device to adopt a continuous detection mode to detect the target signal to reduce the latency.

[0088] For example, when the service has low requirements for latency but hopes that the terminal device saves energy consumption, the network device can instruct the terminal device to adopt a periodic detection mode to detect the target signal to reduce the power consumption.

[0089] In a possible implementation, the target signal can be LP-WUS. When the MR of the terminal device is in any sleep state, the LP-WUR of the terminal device can listen for and detect LP-WUS to determine whether to wake up the MR.

[0090] In a possible implementation, the target signal can include sequences. For example, the target signal can be, such as, an m-sequence, a PN (Pseudo-Noise) sequence, a Zadoff-Chu sequence, or any other suitable sequence, which is not limited herein.

[0091] In a possible implementation, the target signal can include bit information. For example, the target signal can be, such as, an encoding or a bitmap (bitmap) with 8 bits, 16 bits, or any other suitable number of bits, which is not limited herein.

[0092] In a possible implementation, the target signal can have a first format or a second format, where the first format and the second format are different.

[0093] Optionally, when the target signal includes sequences, the length of the first format can be less than the length of the second format.

[0094] For example, the length of the sequence of the first format can be less than (or less than or equal to) a first preset length threshold, the length of the sequence of the second format can be greater than or equal to (or greater than) a second preset length threshold, and the first preset length threshold can be less than or equal to the second preset length threshold.

[0095] For example, the length of the sequence in the second format can be an integer multiple of the length of the sequence in the first format.

[0096] Optionally, when the target signal includes a sequence, the length of the first format can be greater than the length of the second format.

[0097] For example, the length of the sequence in the first format can be greater than (or greater than or equal to) a first preset length threshold, the length of the sequence in the second format can be less than or equal to (or less than) a second preset length threshold, and the first preset length threshold can be greater than or equal to the second preset length threshold.

[0098] For example, the length of the sequence in the first format can be an integer multiple of the length of the sequence in the second format.

[0099] Optionally, when the target signal includes bit information, the content carried by the target signal in the first format can be less than the content carried by the target signal in the second format.

[0100] For example, the number of bits of the bit information in the first format can be less than (or less than or equal to) a first preset bit number threshold, the number of bits of the bit information in the second format can be greater than or equal to (or greater than) a second preset bit number threshold, and the first preset bit number threshold can be less than or equal to the second preset bit number threshold, so that the content carried by the target signal in the first format is less than the content carried by the target signal in the second format.

[0101] For example, the content carried by the target signal in the first format can be a UE group ID; while the content carried by the target signal in the second format can be a dedicated ID of a specific UE, or can further carry any other suitable information such as cell information, which is not limited here.

[0102] Optionally, when the target signal includes bit information, the content carried by the target signal in the first format can be more than the content carried by the target signal in the second format.

[0103] For example, the number of bits of the bit information in the first format can be greater than (or greater than or equal to) a first preset bit number threshold, the number of bits of the bit information in the second format can be less than or equal to (or less than) a second preset bit number threshold, and the first preset bit number threshold can be greater than or equal to the second preset bit number threshold, so that the content carried by the target signal in the first format is more than the content carried by the target signal in the second format.

[0104] For example, the content carried by the target signal in the first format can be a dedicated ID of a specific UE, or can further carry any other suitable information such as cell information; while the content carried by the target signal in the second format can be a UE group ID, which is not limited here.

[0105] In a possible implementation, the continuous detection mode can be used to detect a target signal with a first format.

[0106] For example, since the LP-WUR of the terminal device adopting the continuous detection mode is always on, it can continuously maintain the listening and / or detection of the LP-WUS. Therefore, the LP-WUS can adopt a sequence with a shorter length or bit information with fewer bits to reduce the overhead of the communication system.

[0107] In a possible implementation, the periodic detection mode can be used to detect a target signal with a second format.

[0108] For example, since the LP-WUR of the terminal device adopting the periodic detection mode is in an alternating on / off state, the LP-WUS can adopt a sequence with a longer length or bit information with more bits to ensure that the LP-WUS can be detected when the LP-WUR is on.

[0109] The first information sent by the network device to the terminal device includes indication information for indicating that the terminal device adopts an appropriate detection mode to detect the target signal. Generally speaking, the indication information can include explicit indication or implicit indication.

[0110] In a possible implementation, the first information can include first indication information, and the first indication information is used to indicate that the detection mode of the terminal device is the continuous detection mode or the periodic detection mode.

[0111] For example, the first information sent by the network device to the terminal device can include first indication information (the first indication information can be called mode indication information) to indicate that the terminal device adopts the continuous detection mode or the periodic detection mode to detect the target signal.

[0112] In a possible implementation, the first information can include second indication information, and the second indication information is used to indicate that the target signal of the terminal device has a first format or a second format.

[0113] For example, when the continuous detection mode is pre-configured to detect a target signal with a first format, and the periodic detection mode is used to detect a target signal with a second format, the first information sent by the network device to the terminal device can include second information (the second indication information can be called format indication information), by indicating the format of the target signal (i.e., the first format or the second format), to indicate that the terminal device adopts the continuous detection mode or the periodic detection mode to detect the target signal.

[0114] In a possible implementation, the network device may send a synchronization signal to the terminal device to send the first information, and the synchronization signal has a first characteristic indicating the first information.

[0115] Optionally, the first characteristic may include the group to which the sequence of the synchronization signal belongs, that is, the first information may be indicated by the group to which the sequence of the synchronization signal belongs. In other words, the terminal device may obtain the first information according to the group to which the sequence of the synchronization signal belongs, so as to determine the detection mode for the target signal. This application does not limit the specific grouping method.

[0116] For example, according to a preset rule, the sequences of the synchronization signals may be grouped according to the index of the sequence of the synchronization signal. For example, the sequences of the synchronization signals may be grouped according to the magnitude of the index, or the sequences of the synchronization signals may be grouped according to the parity of the index. Different groups of the synchronization signals may indicate different detection modes for the terminal device to the target signal. The terminal device may obtain the group to which the sequence of the synchronization signal belongs by detecting the synchronization signal, so as to determine to detect the target signal in a continuous mode or a periodic mode.

[0117] Optionally, the first characteristic may include the coding method of the synchronization signal, that is, the first information may be indicated by the coding method of the synchronization signal. In other words, the terminal device may obtain the first information according to the coding method of the synchronization signal, so as to determine the detection mode for the target signal. This application does not limit the specific coding method.

[0118] For example, according to a preset rule, source coding or channel coding may be performed on the synchronization signal, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0119] For example, according to a preset rule, linear code coding or convolutional code coding may be performed on the synchronization signal, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0120] For example, according to a preset rule, polar code coding or low-density parity-check (LDPC) code coding may be performed on the synchronization signal, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0121] Optionally, the first characteristic may include the scrambling manner of the synchronization signal, that is, the first information may be indicated by the scrambling manner of the synchronization signal. In other words, the terminal device may obtain the first information according to the scrambling manner of the synchronization signal, so as to determine the detection mode for the target signal. The present application does not limit the specific scrambling manner.

[0122] For example, according to a preset rule, the synchronization signal may be scrambled with different specific sequences (for example, PN sequence, or m sequence), and different specific sequences implicitly indicate a continuous monitoring mode or a periodic detection mode, so that the terminal device can obtain the first information according to the specific scrambling sequence and determine to detect the target signal in a continuous mode or a periodic mode.

[0123] For example, according to a preset rule, the first information may be obtained according to the index of the sequence used to scramble the synchronization signal. For example, grouping may be performed according to the magnitude of the index of the scrambling sequence, or grouping may be performed according to the parity of the index of the scrambling sequence. Different groupings may indicate different detection modes of the terminal device for the target signal. The terminal device may determine the group to which the scrambling sequence of the synchronization signal belongs by detecting the synchronization signal, so as to determine to detect the target signal in a continuous mode or a periodic mode.

[0124] Optionally, the first characteristic may include the masking manner of the synchronization signal, that is, the first information may be indicated by the masking manner of the synchronization signal. In other words, the terminal device may obtain the first information according to the masking manner of the synchronization signal, so as to determine the detection mode for the target signal. The present application does not limit the specific masking manner.

[0125] For example, according to a preset rule, the synchronization signal may be masked with different specific masking sequences (for example, PN sequence, or m sequence), and different specific masking sequences implicitly indicate a continuous monitoring mode or a periodic detection mode, so that the terminal device can obtain the first information according to the specific masking sequence and determine to detect the target signal in a continuous mode or a periodic mode.

[0126] For example, according to a preset rule, the first information can be obtained based on the index of the sequence or mask for masking the synchronization signal. For example, grouping can be performed according to the magnitude of the index of the masking sequence or mask, or according to the parity of the index of the masking sequence or mask. Different groupings can indicate different detection modes of the terminal device for the target signal. The terminal device can determine the group to which the sequence or mask for masking the synchronization signal belongs by detecting the synchronization signal, so as to determine whether to detect the target signal in a continuous mode or a periodic mode. For example, the index of the sequence or mask for masking can be from 0 to 15. When grouping according to the magnitude of the index, it can be that the indexes from 0 to 7 are in one group, and the indexes from 8 to 15 are in another group, or grouping can be performed according to the parity of the index. Different groupings of the index of the sequence or mask for masking the synchronization signal can indicate different detection modes of the terminal device for the target signal. By obtaining the grouping of the index of the sequence or mask for masking the synchronization signal, the terminal device can determine whether to detect the target signal in a continuous mode or a periodic mode.

[0127] Optionally, the first characteristic may include the transmission symbol index of the synchronization signal, that is, the first information can be indicated by the transmission symbol index of the synchronization signal. In other words, the terminal device can obtain the first information based on the transmission symbol index of the synchronization signal, so as to determine the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0128] For example, according to a preset rule, the continuous monitoring mode or the periodic detection mode can be implicitly indicated based on the transmission symbol index of the synchronization signal. For example, indication can be performed according to the magnitude of the index relative to a preset value, or according to the parity of the index. When the synchronization signal is multiple consecutive transmission symbols, the indication can be based on the index of the first transmission symbol. The terminal device can obtain the first information based on the transmission symbol index of the synchronization signal, and determine whether to detect the target signal in a continuous mode or a periodic mode.

[0129] In a possible implementation, the network device can send a low-power synchronization signal (LP-SS) to the terminal device to send the first information. The LP-SS is at least used for the LP-WUR to perform coarse time synchronization and coarse frequency synchronization with respect to the network device, so as to facilitate the LP-WUR to receive the LP-WUS to wake up the MR. The LP-SS has a second characteristic indicating the first information. This application does not limit the name of the low-power synchronization signal.

[0130] Optionally, the second characteristic may include the group to which the sequence of the LP-SS belongs, that is, the first information may be indicated by the group to which the sequence of the LP-SS belongs. In other words, the terminal device may obtain the first information according to the group to which the sequence of the LP-SS belongs, so as to determine the detection mode for the target signal. This application does not limit the specific grouping method.

[0131] For example, according to a preset rule, the sequences of the LP-SS may be grouped according to the index of the sequence of the LP-SS. For example, the sequences of the LP-SS may be grouped according to the magnitude of the index, or the sequences of the LP-SS may be grouped according to the parity of the index. Different groups of the LP-SS may indicate different detection modes of the terminal device for the target signal. The terminal device may obtain the group to which the sequence of the LP-SS belongs by detecting the LP-SS, so as to determine to detect the target signal in a continuous mode or a periodic mode.

[0132] Optionally, the second characteristic may include the coding method of the LP-SS, that is, the first information may be indicated by the coding method of the LP-SS. In other words, the terminal device may obtain the first information according to the coding method of the LP-SS, so as to determine the detection mode for the target signal. This application does not limit the specific coding method.

[0133] For example, according to a preset rule, source coding or channel coding may be performed on the LP-SS, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0134] For example, according to a preset rule, linear code coding or convolutional code coding may be performed on the LP-SS, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0135] For example, according to a preset rule, Polar code coding or low density parity check (LDPC) code coding may be performed on the LP-SS, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0136] Optionally, the second characteristic may include the scrambling manner of the LP-SS, that is, the first information may be indicated by the scrambling manner of the LP-SS. In other words, the terminal device may obtain the first information according to the scrambling manner of the LP-SS, so as to determine the detection mode for the target signal. This application does not limit the specific scrambling manner.

[0137] For example, according to a preset rule, the LP-SS may be scrambled with different specific sequences (for example, PN sequence, or m sequence). Different specific sequences implicitly indicate the continuous monitoring mode or the periodic detection mode, so that the terminal device can obtain the first information according to the specific scrambling sequence and determine to detect the target signal in the continuous mode or the periodic mode.

[0138] For example, according to a preset rule, the first information may be obtained according to the index of the sequence used to scramble the LP-SS. For example, grouping may be performed according to the magnitude of the index of the scrambling sequence, or according to the parity of the index of the scrambling sequence. Different groups may indicate different detection modes of the terminal device for the target signal. The terminal device may determine the group to which the scrambling sequence of the synchronization signal belongs by detecting the LP-SS, so as to determine to detect the target signal in the continuous mode or the periodic mode.

[0139] Optionally, the second characteristic may include the masking manner of the LP-SS, that is, the first information may be indicated by the masking manner of the LP-SS. In other words, the terminal device may obtain the first information according to the masking manner of the LP-SS, so as to determine the detection mode for the target signal. This application does not limit the specific masking manner.

[0140] For example, according to a preset rule, the LP-SS may be masked with different specific masking sequences (for example, PN sequence, or m sequence). Different specific masking sequences implicitly indicate the continuous monitoring mode or the periodic detection mode, so that the terminal device can obtain the first information according to the specific masking sequence and determine to detect the target signal in the continuous mode or the periodic mode.

[0141] For example, the first information can be obtained according to a preset rule based on the index of the sequence or mask for masking the LP-SS. For example, grouping can be performed according to the magnitude of the index of the masking sequence or mask, or according to the parity of the index of the masking sequence or mask. Different groupings can indicate different detection modes of the terminal device for the target signal. The terminal device can determine the group to which the sequence or mask for masking the LP-SS belongs by detecting the LP-SS, so as to determine to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masking sequence or mask can be from 0 to 15. If grouping is performed according to the magnitude of the index, it can be that indices 0 to 7 are in one group and indices 8 to 15 are in one group, or grouping can be performed according to the parity of the index. Different groupings of the index of the sequence or mask for masking the LP-SS can indicate different detection modes of the terminal device for the target signal. The terminal device can determine to detect the target signal in a continuous mode or a periodic mode by obtaining the grouping of the index of the sequence or mask for masking the LP-SS.

[0142] Optionally, the second characteristic may include the transmission symbol index of the LP-SS, that is, the first information can be indicated by the transmission symbol index of the LP-SS. In other words, the terminal device can obtain the first information according to the transmission symbol index of the LP-SS, so as to determine the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0143] For example, a continuous monitoring mode or a periodic detection mode can be implicitly indicated according to a preset rule based on the transmission symbol index of the LP-SS. For example, indication can be made according to the magnitude of the index relative to a preset value, or according to the parity of the index. When the LP-SS is multiple consecutive transmission symbols, indication can be made based on the index of the first transmission symbol. The terminal device can obtain the first information according to the transmission symbol index of the LP-SS and determine to detect the target signal in a continuous mode or a periodic mode.

[0144] In a possible implementation, the first information is allowed to be carried in a broadcast message, an SIB message, a common control message, a DCI, an RRC message, a MACCE message, or any suitable control message, which is not limited herein.

[0145] In a possible implementation, the network device sends the first information to the terminal device, including: the network device receives auxiliary information from the terminal device; and in response to the reception of the auxiliary information, sends a response message returned in response to the auxiliary information to the terminal device to send the first information.

[0146] Specifically, the terminal device can send auxiliary information to the network device to assist the network device in determining the transmission mode of the target signal and instruct the terminal device, so that the terminal device can detect the target signal in a corresponding detection mode.

[0147] Optionally, the auxiliary information can include second information, which can also be referred to as the capability information of the terminal device or the terminal device capability, and is used to indicate the capabilities of the terminal device, including but not limited to the detection modes supported by the terminal device (e.g., continuous monitoring, or periodic detection, etc.), or the modulation modes of the target signal supported by the terminal device (e.g., OOK, FSK, or ASK, etc.).

[0148] Optionally, the auxiliary information can include third information, which can also be described as the expectation of the terminal device, and is used for the terminal device to report the detection mode (e.g., continuous monitoring, or periodic detection, etc.) expected to be used for performing signal detection operations on the target signal.

[0149] The third information can be determined by the terminal device based on service requirements and / or device status.

[0150] For example, if the terminal device has high requirements for latency in the service, it can report the third information that it expects to use the continuous detection mode to detect the target signal.

[0151] For example, if the terminal device has low requirements for latency in the service and / or the battery power of the terminal device is insufficient and / or the terminal device enters the low-power mode, etc., it can report the third information that it expects to use the periodic detection mode to detect the target signal.

[0152] In response to receiving the auxiliary information from the terminal device, the network device can feedback a response message to the terminal device based on the terminal device capability and / or the detection mode expected to be used by the terminal device, so as to send the first information.

[0153] S202. The terminal device obtains the first information and determines the detection mode for the target signal according to the first information.

[0154] Among them, the detection mode can include a continuous detection mode or a periodic detection mode.

[0155] In a possible implementation, the terminal device can support two or more detection modes for the target signal. For example, the detection mode can include a continuous detection mode and / or a periodic detection mode. Correspondingly, the network device can correspondingly support two or more transmission modes for the target signal.

[0156] The network device can send the first information to the terminal device according to service needs to instruct the terminal device to use an appropriate detection mode to detect the target signal.

[0157] For example, when the service requires low latency, the network device may instruct the terminal device to adopt a continuous detection mode to detect the target signal to reduce the latency.

[0158] For example, when the service has low requirements for latency but hopes that the terminal device saves energy consumption, the network device may instruct the terminal device to adopt a periodic detection mode to detect the target signal to reduce the power consumption.

[0159] After obtaining the first information, the terminal device may determine the detection mode for the target signal according to the indication of the first information.

[0160] In a possible implementation, the target signal may be LP-WUS. When the MR of the terminal device is in any sleep state, the LP-WUR of the terminal device may listen for and detect LP-WUS to determine whether to wake up the MR.

[0161] In a possible implementation, the target signal may include a sequence. For example, the target signal may be an m-sequence, a PN sequence, a Zadoff-Chu sequence, or any other suitable sequence, which is not limited herein.

[0162] In a possible implementation, the target signal may include bit information. For example, the target signal may be an encoding or a bitmap having 8 bits, 16 bits, or any other suitable number of bits, which is not limited herein.

[0163] In a possible implementation, the target signal may have a first format or a second format, where the first format and the second format are different.

[0164] Optionally, when the target signal includes a sequence, the length of the first format may be less than the length of the second format.

[0165] For example, the length of the sequence in the first format may be less than (or less than or equal to) a first preset length threshold, the length of the sequence in the second format may be greater than or equal to (or greater than) a second preset length threshold, and the first preset length threshold may be less than or equal to the second preset length threshold.

[0166] For example, the length of the sequence in the second format may be an integer multiple of the length of the sequence in the first format.

[0167] Optionally, when the target signal includes a pre-sequence, the length of the first format may be greater than the length of the second format.

[0168] For example, the length of the sequence in the first format may be greater than (or greater than or equal to) a first preset length threshold, the length of the sequence in the second format may be less than or equal to (or less than) a second preset length threshold, and the first preset length threshold may be greater than or equal to the second preset length threshold.

[0169] For example, the length of the sequence in the first format may be an integer multiple of the length of the sequence in the second format.

[0170] Optionally, when the target signal includes bit information, the content carried by the target signal in the first format may be less than the content carried by the target signal in the second format.

[0171] For example, the number of bits of the bit information in the first format may be less than (or less than or equal to) a first preset bit number threshold, the number of bits of the bit information in the second format may be greater than or equal to (or greater than) a second preset bit number threshold, and the first preset bit number threshold may be less than or equal to the second preset bit number threshold, so that the content carried by the target signal in the first format is less than the content carried by the target signal in the second format.

[0172] For example, the content carried by the target signal in the first format may be a UE group ID; while the content carried by the target signal in the second format may use a dedicated ID of a specific UE, or may further carry any other appropriate information such as cell information, which is not limited here.

[0173] Optionally, when the target signal includes bit information, the content carried by the target signal in the first format may be more than the content carried by the target signal in the second format.

[0174] For example, the number of bits of the bit information in the first format may be greater than (or greater than or equal to) a first preset bit number threshold, the number of bits of the bit information in the second format may be less than or equal to (or less than) a second preset bit number threshold, and the first preset bit number threshold may be greater than or equal to the second preset bit number threshold, so that the content carried by the target signal in the first format is more than the content carried by the target signal in the second format.

[0175] For example, the content carried by the target signal in the first format may use a dedicated ID of a specific UE, or may further carry any other appropriate information such as cell information; while the content carried by the target signal in the second format may be a UE group ID, which is not limited here.

[0176] In a possible implementation manner, the continuous detection mode may be used to detect the target signal having the first format.

[0177] For example, since the LP-WUR of a terminal device adopting a continuous detection mode is always on, it can continuously monitor and / or detect the LP-WUS. Therefore, the LP-WUS can adopt a sequence with a shorter length or bit information with fewer bits to reduce the overhead of the communication system.

[0178] In a possible implementation, the periodic detection mode can be used to detect a target signal with a second format.

[0179] For example, since the LP-WUR of a terminal device adopting a periodic detection mode is in an alternating on / off state, the LP-WUS can adopt a sequence with a longer length or bit information with more bits to ensure that the LP-WUS can be detected when the LP-WUR is on.

[0180] The first information obtained by the terminal device includes indication information indicating that the terminal device adopts an appropriate detection mode to detect the target signal. Generally speaking, the indication information can include explicit indication or implicit indication. The terminal device can determine the detection mode for detecting the target information based on the explicit indication information or implicit indication information.

[0181] In a possible implementation, the first information can include first indication information, and the first indication information is used to indicate that the detection mode of the terminal device is a continuous detection mode or a periodic detection mode.

[0182] For example, the first information sent by the network device to the terminal device can include first indication information (the first indication information can be called mode indication information) to indicate that the terminal device adopts a continuous detection mode or a periodic detection mode to detect the target signal.

[0183] In a possible implementation, the first information can include second indication information, and the second indication information is used to indicate that the target signal of the terminal device has a first format or a second format.

[0184] For example, when it is pre-configured that the continuous detection mode is used to detect a target signal with a first format, and the periodic detection mode is used to detect a target signal with a second format, the first information sent by the network device to the terminal device can include second indication information (the second indication information can be called format indication information), and by indicating the format of the target signal (i.e., the first format or the second format), it is used to indicate that the terminal device adopts a continuous detection mode or a periodic detection mode to detect the target signal.

[0185] In a possible implementation, the network device can send a synchronization signal to the terminal device to send the first information, and the synchronization signal has a first characteristic indicating the first information.

[0186] Optionally, the first characteristic may include the group to which the sequence of synchronization signals belongs, that is, the first information may be indicated by the group to which the sequence of synchronization signals belongs. In other words, the terminal device may obtain the first information according to the group to which the sequence of synchronization signals belongs, so as to determine the detection mode for the target signal. This application does not limit the specific grouping method.

[0187] For example, according to a preset rule, the sequences of synchronization signals may be grouped according to the indexes of the sequences of synchronization signals. For example, the sequences of synchronization signals may be grouped according to the magnitude of the indexes, or the sequences of synchronization signals may be grouped according to the parity of the indexes. Different groups of synchronization signals may indicate different detection modes for the terminal device to the target signal. The terminal device may obtain the group to which the sequence of synchronization signals belongs by detecting the synchronization signals, so as to determine to detect the target signal in a continuous mode or a periodic mode.

In other words, the terminal device may obtain the first information according to the coding method of the synchronization signal, so as to determine the detection mode for the target signal. This application does not limit the specific coding method.

[0189] For example, according to a preset rule, source coding or channel coding may be performed on the synchronization signal, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0190] For example, according to a preset rule, linear code coding or convolutional code coding may be performed on the synchronization signal, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0191] For example, according to a preset rule, Polar code coding or LDPC code coding may be performed on the synchronization signal, so that the terminal device may obtain the first information according to the coding method and determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0192] Optionally, the first characteristic may include the scrambling method of the synchronization signal, that is, the first information may be indicated by the scrambling method of the synchronization signal. In other words, the terminal device may obtain the first information according to the scrambling method of the synchronization signal, so as to determine the detection mode for the target signal.

[0194] For example, according to a preset rule, the first information can be obtained according to the index of the sequence used to scramble the synchronization signal. For example, grouping can be performed according to the magnitude of the index of the scrambling sequence, or grouping can be performed according to the parity of the index of the scrambling sequence. Different groupings can indicate different detection modes of the terminal device for the target signal. The terminal device can determine the group to which the scrambling sequence of the synchronization signal belongs by detecting the synchronization signal, so as to determine to detect the target signal in a continuous mode or a periodic mode.

In other words, the terminal device can obtain the first information according to the masking method of the synchronization signal, so as to determine the detection mode for the target signal. The present application does not limit the specific masking method.

[0196] For example, according to a preset rule, the synchronization signal can be masked with different specific masking sequences (e.g., PN sequence, or m sequence), and different specific masking sequences implicitly indicate a continuous monitoring mode or a periodic detection mode, so that the terminal device can obtain the first information according to the specific masking sequence and determine to detect the target signal in a continuous mode or a periodic mode.

[0197] For example, according to a preset rule, the first information can be obtained according to the index of the sequence or mask used to mask the synchronization signal. For example, grouping can be performed according to the magnitude of the index of the masking sequence or mask, or grouping can be performed according to the parity of the index of the masking sequence or mask. Different groupings can indicate different detection modes of the terminal device for the target signal. The terminal device can determine the group to which the masking sequence or mask of the synchronization signal belongs by detecting the synchronization signal, so as to determine to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masking sequence or mask can be 0 to 15. If grouping is performed according to the magnitude of the index, it can be that indexes 0 to 7 are in one group and indexes 8 to 15 are in one group, or grouping can be performed according to the parity of the index. Different groupings of the index of the masking sequence or mask of the synchronization signal can indicate different detection modes of the terminal device for the target signal. The terminal device can determine to detect the target signal in a continuous mode or a periodic mode by obtaining the grouping of the index of the masking sequence or mask of the synchronization signal.

[0198] Optionally, the first feature may include the transmission symbol index of the synchronization signal, that is, the first information may be indicated by the transmission symbol index of the synchronization signal. In other words, the terminal device may obtain the first information according to the transmission symbol index of the synchronization signal, so as to determine the detection mode of the target signal. This application does not limit the specific transmission symbol index.

[0199] For example, according to a preset rule, the continuous monitoring mode or the periodic detection mode may be implicitly indicated according to the transmission symbol index of the synchronization signal. For example, the indication may be made according to the size of the index relative to a preset value, or according to the parity of the index. When the synchronization signal is a plurality of consecutive transmission symbols, the indication may be based on the index of the first transmission symbol. The terminal device may obtain the first information according to the transmission symbol index of the synchronization signal, and determine to detect the target signal in a continuous mode or a periodic mode.

[0200] In a possible implementation, the network device may send a low power synchronization signal (LP-SS) to the terminal device to send the first information. The LP-SS is at least used for the time coarse synchronization and frequency coarse synchronization of the LP-WUR with respect to the network device, so as to facilitate the LP-WUR to receive the LP-WUS to wake up the MR. The LP-SS has a second feature indicating the first information. This application does not limit the name of the low power synchronization signal.

[0201] Optionally, the second feature may include the packet to which the sequence of the LP-SS belongs, that is, the first information may be indicated by the packet to which the sequence of the LP-SS belongs. In other words, the terminal device may obtain the first information according to the packet to which the sequence of the LP-SS belongs, so as to determine the detection mode of the target signal. This application does not limit the specific packet mode.

[0202] For example, according to a preset rule, the sequences of the LP-SS may be grouped according to the index of the sequence of the LP-SS. For example, the sequences of the LP-SS may be grouped according to the size of the index, or the sequences of the LP-SS may be grouped according to the parity of the index. Different packets of the LP-SS may indicate different detection modes of the terminal device for the target signal. The terminal device may determine the packet to which the sequence of the LP-SS belongs by detecting the LP-SS, so as to determine to detect the target signal in a continuous mode or a periodic mode.

[0203] Optionally, the second feature may include the coding method of the LP-SS, that is, the first information may be indicated by the coding method of the LP-SS. In other words, the terminal device may obtain the first information according to the coding method of the LP-SS, so as to determine the detection mode of the target signal. This application does not limit the specific coding method.

[0204] For example, source coding or channel coding can be performed on the LP-SS according to a preset rule, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0205] For example, linear code coding or convolutional code coding can be performed on the LP-SS according to a preset rule, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0206] For example, Polar code coding or low-density parity-check (LDPC) code coding can be performed on the LP-SS according to a preset rule, so that the terminal device can obtain the first information according to the coding method, determine to detect the target signal in a continuous mode or a periodic mode, or determine to detect the target signal in a periodic mode or a continuous mode.

[0207] Optionally, the second characteristic may include the scrambling method of the LP-SS, that is, the first information can be indicated by the scrambling method of the LP-SS. In other words, the terminal device can obtain the first information according to the scrambling method of the LP-SS, so as to determine the detection mode of the target signal. The present application does not limit the specific scrambling method.

[0208] For example, according to a preset rule, the LP-SS can be scrambled with different specific sequences (for example, PN sequence or m sequence). Different specific sequences implicitly indicate a continuous monitoring mode or a periodic detection mode, so that the terminal device can obtain the first information according to the specific scrambling sequence and determine to detect the target signal in a continuous mode or a periodic mode.

[0209] For example, according to a preset rule, the first information can be obtained according to the index of the sequence used to scramble the LP-SS. For example, grouping can be performed according to the magnitude of the index of the scrambling sequence, or grouping can be performed according to the parity of the index of the scrambling sequence. Different groups can indicate different detection modes of the terminal device for the target signal. The terminal device can determine to detect the target signal in a continuous mode or a periodic mode by detecting the grouping to which the scrambling sequence of the synchronization signal belongs in the LP-SS.

[0210] Optionally, the second characteristic may include the masking method of the LP-SS, that is, the first information may be indicated by the masking method of the LP-SS. In other words, the terminal device may obtain the first information according to the masking method of the LP-SS, so as to determine the detection mode of the target signal. This application does not limit the specific masking method.

[0211] For example, according to a preset rule, the LP-SS may be masked with different specific masking sequences (for example, PN sequence or m sequence). Different specific masking sequences implicitly indicate the continuous monitoring mode or the periodic detection mode, so that the terminal device can obtain the first information according to the specific masking sequence and determine to detect the target signal in the continuous mode or the periodic mode.

[0212] For example, according to a preset rule, the first information may be obtained according to the index of the sequence or mask used to mask the LP-SS. For example, grouping may be performed according to the size of the index of the masking sequence or mask, or according to the parity of the index of the masking sequence or mask. Different groups may indicate different detection modes of the terminal device for the target signal. The terminal device may determine the group to which the sequence or mask of the masked LP-SS belongs by detecting the LP-SS, so as to determine to detect the target signal in the continuous mode or the periodic mode. For example, the index of the masking sequence or mask may be 0 to 15. When grouped according to the size of the index, it may be that indexes 0 to 7 are in one group and indexes 8 to 15 are in one group, or grouped according to the parity of the index. Different groups of the index of the sequence or mask of the masked LP-SS may indicate different detection modes of the terminal device for the target signal. The terminal device can determine to detect the target signal in the continuous mode or the periodic mode by obtaining the group of the index of the sequence or mask of the masked LP-SS.

[0213] Optionally, the second characteristic may include the transmission symbol index of the LP-SS, that is, the first information may be indicated by the transmission symbol index of the LP-SS. In other words, the terminal device may obtain the first information according to the transmission symbol index of the LP-SS, so as to determine the detection mode of the target signal. This application does not limit the specific transmission symbol index.

[0214] For example, according to a preset rule, the continuous monitoring mode or the periodic detection mode may be implicitly indicated according to the transmission symbol index of the LP-SS. For example, indication may be made according to the size of the index relative to a preset value, or according to the parity of the index. When the LP-SS is multiple consecutive transmission symbols, indication may be made based on the index of the first transmission symbol. The terminal device may obtain the first information according to the transmission symbol index of the LP-SS and determine to detect the target signal in the continuous mode or the periodic mode.

[0215] In a possible implementation, the first information is allowed to be carried in a broadcast message, an SIB message, a common control message, a DCI, an RRC message, a MAC CE message, or any suitable control message, which is not limited herein.

[0216] In a possible implementation, the terminal device obtains the first information, including: the terminal device sends auxiliary information to the network device; and in response to the sending of the auxiliary information, the terminal device receives an acknowledgment message returned by the network device in response to the auxiliary information to obtain the first information.

[0217] Specifically, the terminal device may send auxiliary information to the network device to assist the network device in determining the transmission mode of the target signal and indicating the terminal device, so that the terminal device can detect the target signal in a corresponding detection mode.

[0218] Optionally, the auxiliary information may include second information, which may also be referred to as the capability information of the terminal device or the terminal device capability, and is used to indicate the capabilities of the terminal device, including but not limited to the detection modes supported by the terminal device (for example, continuous monitoring, or periodic detection, etc.), or the modulation modes of the target signal supported by the terminal device (for example, OOK, FSK, or ASK, etc.).

[0219] Optionally, the auxiliary information may include third information, which may also be described as the expectation of the terminal device, and is used for the terminal device to report the detection mode (for example, continuous monitoring, or periodic detection, etc.) expected to be used for performing signal detection operations on the target signal.

[0220] The third information may be determined by the terminal device based on service requirements and / or device status.

[0221] For example, if the terminal device has high requirements for latency in the service, it may report the third information indicating that it expects to use the continuous detection mode to detect the target signal.

[0222] For example, if the terminal device has low requirements for latency in the service and / or the battery power of the terminal device is insufficient and / or the terminal device enters the low-power mode, etc., it may report the third information indicating that it expects to use the periodic detection mode to detect the target signal.

[0223] In response to receiving the auxiliary information from the terminal device, the network device may feedback an acknowledgment message to the terminal device based on the terminal device capabilities and / or the detection mode expected to be used by the terminal device to send the first information.

[0224] S203. The network device sends a target signal to the terminal device.

[0225] After the network device sends the first piece of information to the terminal device to instruct the terminal device to determine the detection mode for the target signal, the target signal may be sent in a form corresponding to the detection mode indicated to the terminal device (for example, the format, length, or carried content of the target signal, etc.).

[0226] Specifically, the network device may send the first piece of information to the terminal device in an explicit indication or implicit indication manner, instruct the detection mode that the terminal device needs to adopt for the target signal, and send the target signal to the terminal device according to the corresponding form of the target signal (for example, the format, length, or carried content of the target signal, etc.) according to the indicated detection mode. The correspondence between the detection mode and the form of the target signal may refer to the relevant description in S201 and will not be elaborated here.

[0227] In a possible implementation manner, when the detection mode indicated by the first piece of information is the continuous detection mode, the network device sending the target signal to the terminal device may include: sending the target signal to the terminal device within a configured time interval.

[0228] Optionally, the configured time interval may include a preconfigured time interval. The preconfigured time interval may be specified by the protocol, indicated by high-layer signaling, or preconfigured in any other suitable manner.

[0229] Optionally, the configured time interval may further include the time interval indicated by the first piece of information. When the first piece of information indicates the continuous detection mode, it may also indicate the time interval for detecting the target signal.

[0230] In a possible implementation manner, when the determined detection mode is the continuous detection mode, the network device sending the target signal to the terminal device may include: repeatedly sending the target signal to the terminal device, where the number of repetitions is greater than or equal to a first preset threshold. For example, the first preset threshold may be 2, that is, the network device repeatedly sends the target signal to the terminal device at least twice.

[0231] In a possible implementation manner, when the determined detection mode is the periodic detection mode, the network device sending the target signal to the terminal device may include: repeatedly sending the target signal to the terminal device, where the number of repetitions is less than or equal to a second preset threshold. For example, the second preset threshold may be 0, that is, the network device does not repeatedly send the target signal to the terminal device.

[0232] S204. The terminal device performs signal detection on the target signal based on the determined detection mode.

[0233] After the terminal device obtains the first information and determines the detection mode for the target signal based on the first information, it can perform signal detection on the target signal in a form corresponding to the determined detection mode (e.g., the format, length, or carried content of the target signal) from the network device based on the determined detection mode.

[0234] Specifically, the terminal device can obtain the first information sent by the network device to the terminal device in an explicit indication or implicit indication manner, determine the detection mode required for the target signal based on the first information, and perform signal detection on the target signal from the network device in accordance with the corresponding form (e.g., the format, length, or carried content of the target signal) according to the determined detection mode. The correspondence between the detection mode and the form of the target signal can refer to the relevant description in S202 and will not be elaborated here.

[0235] In a possible implementation, when the determined detection mode is the continuous detection mode, the terminal device performing signal detection on the target signal from the network device based on the determined detection mode may include: performing signal detection on the target signal from the network device within a configured time interval.

[0236] Optionally, the configured time interval may include a pre-configured time interval. The pre-configured time interval may be specified by the protocol, indicated by high-layer signaling, or pre-configured in any other suitable manner.

[0237] Optionally, the configured time interval may further include the time interval indicated by the first information. While the first information indicates that the detection mode is the continuous detection mode, it may also indicate the time interval for detecting the target signal. The terminal device may also perform detection on the target signal within the time interval indicated by the first information.

[0238] In a possible implementation, when the determined detection mode is the continuous detection mode, the terminal device performing signal detection on the target signal from the network device may include: performing signal detection on the repeatedly sent target signal from the network device, where the number of repetitions is greater than or equal to a first preset threshold. For example, the first preset threshold may be 2, that is, the network device repeatedly sends the target signal to the terminal device at least twice.

[0239] In a possible implementation, when the determined detection mode is the periodic detection mode, the terminal device performing signal detection on the target signal from the network device may include: performing signal detection on the repeatedly sent target signal from the network device, where the number of repetitions is less than or equal to a second preset threshold. For example, the second preset threshold may be 0, that is, the network device does not repeatedly send the target signal to the terminal device.

[0240] InFigure 2 In the described method, a network device sends first information to a terminal device. The terminal device acquires the first information and determines a detection mode for a target signal according to the first information. Among them, the detection mode includes a continuous detection mode or a periodic detection mode. Furthermore, the network device sends the target signal to the terminal device, and the terminal device detects the target signal based on the determined detection mode. Since the network device can indicate the detection mode that the terminal device needs to adopt for the target signal according to service requirements, it can be applied to different application scenarios, which is beneficial to determining a suitable signal detection mode according to service requirements and can balance system latency and energy efficiency.
