Description

Communication processing method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410178252.7 and application name “A Communication Processing Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication processing method and a communication device. Background Art

[0003] With the development of wireless communication technology, higher requirements are being placed on device power consumption. In addition to latency, reliability, and availability, the energy efficiency of user equipment (UE) is also crucial for 5G systems. Currently, 5G devices may need to be charged weekly or daily depending on individual usage. Typically, 5G devices tend to consume tens of milliwatts of power when in the idle or inactive state of radio resource control (RRC) and hundreds of milliwatts of power when in the RRC connected state. How to extend battery life is a prerequisite for improving energy efficiency and enhancing user experience.

[0004] To improve battery life, the field has introduced an ultra-low power wake-up signal (LP-WUS) mechanism. That is, the user uses a separate low power wake-up receiver (LP-WUR) to receive a low power wake-up signal, which is used to wake up the main radio (MR) for data transmission and reception. When the UE does not detect the low power wake-up signal, the main receiver is in a deep sleep state, which further reduces the power consumption of the terminal.

[0005] Therefore, balancing latency and energy efficiency is one of the key focuses of 5G communications. Summary of the Invention

[0060] It should be noted that Figure 1 is only a schematic diagram of the architecture of a communication system. The communication system 100 may also include other devices, such as wireless relay devices, wireless backhaul devices, core network devices, etc., which are not shown in Figure 1. The embodiments of the present application do not limit the number of various devices included in the communication system.

[0061] The embodiments of the present application can be applied to both downlink and uplink signal transmission. 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. The transmission direction of the signal in the embodiments of the present application is not limited.

[0062] The network device 110 and the terminal device 120 can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both a licensed spectrum and an unlicensed spectrum. The network device 110 and the terminal device 120 can communicate through a spectrum below 6 gigahertz (GHz), or through a spectrum above 6 GHz, or through both a spectrum below 6 GHz and a spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used between the network device 110 and the terminal device 120.

[0063] In the embodiments of the present application, the time domain symbols may be orthogonal frequency division multiplexing (OFDM) symbols or discrete Fourier transform spread OFDM (DFT-s-OFDM) symbols. Unless otherwise specified, the symbols in the embodiments of the present application refer to time domain symbols.

[0064] It can be understood that in the 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 merely examples of downlink data channels, downlink control channels and uplink data channels, respectively. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of the present application do not limit this.

[0065] In an embodiment of the present application, a low power wake-up signal (LP-WUS) is introduced into the communication standard. The LP-WUS is received using a separate receiver, referred to as a low power wake-up radio receiver (LP-WUR) 121. The terminal device 120 needs to use a main radio (MR) 122 to process downlink and / or uplink data normally.

[0066] In a possible implementation, when the LP-WUR 121 of the terminal device 120 receives the LP-WUS and the LP-WUS indicates wake-up, the terminal device 120 turns on the MR 122 to receive and process downlink and / or uplink signals.

[0067] In one 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.

[0068] Optionally, the LP-WUS signal may be used in radio resource control (RRC) connected, inactive, idle, and other states.

[0069] In a possible implementation, the sleep states of the MR 122 may include four types: ultra-deepsleep, deep sleep, light sleep, and micro sleep.

[0070] To ensure that the LP-WUR 121 consumes less power when in the ON state, the LP-WUR 121 may optionally use envelope detection to determine information carried by the received LP-WUR signal.

[0071] In one possible implementation, envelope detection includes amplitude detection or energy detection, whereby the terminal device determines the specific information carried by the LP-WUS signal by sending the amplitude or energy level of the LP-WUS signal to 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 modes for LP-WUS.

[0072] In one possible implementation, the LP-WUR can be designed based on orthogonal frequency division multiplexing (OFDM) to achieve better signal coverage. In this case, the LP-WUR 121 can have a certain decoding capability and can receive and decode OFDM-based wireless signals. The OFDM-based LP-WUR 121 consumes less power than the MR in the ON state, but consumes more power than the envelope detection LP-WUR 121.

[0073] In one possible implementation, the operating mode (detection mode) of the LP-WUR 121 may include the following two:

[0074] The continuous monitoring mode means that the LP-WUR 121 is always in the on state. In this embodiment, the continuous monitoring mode can effectively reduce the delay.

[0075] Duty cycle mode, that is, the LP-WUR 121 is in an on state during certain time periods and in an off state during other time periods. In this embodiment, the duty cycle mode can further reduce the power consumption of the LP-WUR 121.

[0076] In one possible implementation, the network device 110 can wake up the terminal devices 120 in the cell that support LP-WUS, or change the sleep state of these terminal devices 120 by sending an LP-WUS. For the terminal device 120 that supports LP-WUS, at least one LP-WUS signal is received through the LP-WUR 121, and the MR 122 is awakened or the sleep state is changed based on the information carried by the received LP-WUS signal.

[0077] Optionally, the change of the sleep state of MR 122 refers to switching between states such as ultra-deep sleep, deep sleep, light sleep, and micro sleep, and the awakening of MR 122 refers to the transition of MR 122 from any sleep state to an awake state.

[0078] In one possible implementation, the LP-WUS design can include the following two approaches:

[0079] Alternatively, the constant envelope-based LP-WUS can have obvious energy-saving advantages.

[0080] Alternatively, OFDM-based LP-WUS can have a wider coverage, support more functions, and have higher reliability.

[0081] In one possible implementation, two or more operating modes of the LP-WUR 121 are supported by the network device 110 and the terminal device 120. Optionally, the network device 110 needs to determine the capabilities of the LP-WUR 121 of the terminal device 120 in the cell so as to send the LP-WUR to the terminal device 120 in an appropriate manner.

[0082] In one possible implementation, terminal device 120 reports its terminal device capabilities, allowing network device 110 to understand the LP-WUS formats that terminal device 120 can receive. These terminal device capabilities can be described from the perspective of LP-WUS detection modes or from the perspective of LP-WUR 121 capabilities. Alternatively, if the terminal device capabilities of terminal device 120 are not reported, they are determined according to a default principle or by network device 110.

[0083] FIG2 is a flow chart illustrating a communication processing method provided in an embodiment of the present application. The method execution subject shown in FIG2 may be the terminal device and network device mentioned above. Alternatively, the method execution subject shown in FIG2 may be a chip in a terminal device and a chip in a network device, which is not limited in the embodiment of the present application. FIG2 illustrates the method execution subject using a terminal device and a network device as an example.

[0084] S201. The network device sends first information to the terminal device.

[0085] The first information is used to instruct the terminal device to determine a detection mode for the target signal based on the first information, and the detection mode includes a continuous detection mode or a periodic detection mode.

[0086] In one possible implementation, the terminal device may support two or more detection modes for the target signal. For example, the detection mode may include a continuous detection mode and / or a periodic detection mode. Corresponding to the signal detection mode supported by the terminal device, the network device may correspondingly support two or more transmission modes for the target signal.

[0087] The network device may send first information to the terminal device according to service requirements to instruct the terminal device to adopt an appropriate detection mode to detect the target signal.

[0088] For example, if the service requires low latency, the network device can instruct the terminal device to use a continuous detection mode to detect the target signal to reduce latency.

[0089] For example, if the service does not require high latency but hopes that the terminal device can save energy, the network device can instruct the terminal device to use a periodic detection mode to detect the target signal to reduce power consumption.

[0090] In a possible implementation, the target signal may be an LP-WUS. When the MR of the terminal device is in any sleep state, the LP-WUR of the terminal device may monitor and detect the LP-WUS to determine whether to wake up the MR.

[0091] In a possible implementation, the target signal may include a sequence. For example, the target signal may be an m-sequence, a PN (Pseudo-Noise) sequence, a Zadoff-Chu sequence, or any other suitable sequence, which is not limited here.

[0092] In a possible implementation, the target signal may include bit information. For example, the target signal may be a code or a bitmap having 8 bits, 16 bits, or any other suitable number of bits, which is not limited here.

[0093] In a possible implementation manner, the target signal may have a first format or a second format, wherein the first format and the second format are different.

[0094] Optionally, when the target signal includes a sequence, the length of the first format may be smaller than the length of the second format.

[0095] For example, the length of the sequence in the first format may be less than (or less than or equal to) the first preset length threshold, the length of the sequence in the second format may be greater than or equal to (or greater than) the second preset length threshold, and the first preset length threshold may be less than or equal to the second preset length threshold.

[0096] 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.

[0097] Optionally, when the target signal includes a sequence, the length of the first format may be greater than the length of the second format.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] For example, the number of bits of the bit information in the first format may be less than (or less than or equal to) the 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) the 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.

[0102] For example, the content carried by the target signal in the first format may be the 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 suitable information such as cell information, which is not limited here.

[0103] 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.

[0104] For example, the number of bits of the bit information in the first format may be greater than (or greater than or equal to) the 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) the 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 target signal in the first format carries more content than the content carried by the target signal in the second format.

[0105] 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 suitable information such as cell information; and the content carried by the target signal in the second format may be a UE group ID, which is not limited here.

[0106] In a possible implementation, the continuous detection mode may be used to detect a target signal having a first format.

[0107] For example, since the LP-WUR of the terminal device using the continuous detection mode is always in the on state, it can always keep monitoring and / or detecting the LP-WUS. Therefore, the LP-WUS can use a shorter sequence or bit information with fewer bits to reduce the overhead of the communication system.

[0108] In a possible implementation, the periodic detection mode may be used to detect a target signal having the second format.

[0109] For example, since the LP-WUR of the terminal device using the periodic detection mode is in an alternating on / off state, the LP-WUS can use a longer sequence or bit information with a larger number of bits to ensure that the LP-WUS can be detected when the LP-WUR is in the on state.

[0110] The first information sent by the network device to the terminal device includes instruction information instructing the terminal device to adopt an appropriate detection mode to detect the target signal. Generally speaking, the instruction information may include an explicit instruction or an implicit instruction.

[0111] In a possible implementation, the first information may include first indication information, where 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.

[0112] For example, the first information sent by the network device to the terminal device may include first indication information (the first indication information may be called mode indication information) to instruct the terminal device to detect the target signal using a continuous detection mode or a periodic detection mode.

[0113] In a possible implementation, the first information may include second indication information, where the second indication information is used to indicate that the target signal of the terminal device has the first format or the second format.

[0114] For example, when a continuous detection mode is pre-configured for detecting a target signal having a first format, and a periodic detection mode is pre-configured for detecting a target signal having a second format, the first information sent by the network device to the terminal device may include second information (the second indication information may be called format indication information), which indicates the format of the target signal (i.e., the first format or the second format) to instruct the terminal device to use a continuous detection mode or a periodic detection mode to detect the target signal.

[0115] In a possible implementation manner, the network device may send a synchronization signal to the terminal device to send the first information, where the synchronization signal has a first characteristic indicating the first information.

[0116] 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 based on the group to which the sequence of synchronization signals belongs, thereby determining a detection mode for the target signal. This application does not limit the specific grouping method.

[0117] For example, the sequence of synchronization signals can be grouped according to the index of the sequence of synchronization signals according to a preset rule. For example, the sequence of synchronization signals can be grouped according to the size of the index, or according to the parity of the index. Different groupings of synchronization signals can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the sequence of synchronization signals belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0118] Optionally, the first characteristic may include an encoding method of the synchronization signal, that is, the first information may be indicated by the encoding method of the synchronization signal. In other words, the terminal device may obtain the first information based on the encoding method of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific encoding method.

[0119] For example, the synchronization signal can be source encoded or channel encoded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0120] For example, the synchronization signal can be linearly coded or convolutionally coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0121] For example, the synchronization signal can be polarization coded or low-density parity check (LDPC) coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, and determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0122] Optionally, the first characteristic may include a 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 based on the scrambling method of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific scrambling method.

[0123] For example, the synchronization signal can be encrypted with different specific sequences (for example, PN sequence, or m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0124] For example, the first information can be obtained according to a preset rule based on the index of the sequence used to scramble the synchronization signal. For example, grouping can be performed based on the size of the scrambling sequence index, or based on the parity of the scrambling sequence index. Different groups can indicate different detection modes for the terminal device for the target signal. The terminal device can obtain the group to which the scrambling sequence of the synchronization signal belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0125] Optionally, the first characteristic may include a synchronization signal masking method, that is, the first information may be indicated by the synchronization signal masking method. In other words, the terminal device may obtain the first information based on the synchronization signal masking method, thereby determining the detection mode for the target signal. This application does not limit the specific masking method.

[0126] For example, the synchronization signal can be masked with different specific masking sequences (for example, PN sequence, or m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0127] For example, the first information can be obtained according to the preset rules based on the index of the sequence or mask used to mask the synchronization signal. For example, grouping can be performed according to the size of the index of the masked sequence or mask, or grouping can be performed according to the parity of the index of the masked sequence or mask. Different groups can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the masked sequence or mask of the synchronization signal belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masked sequence or mask can be 0 to 15, and grouping can be performed according to the size of the index, so that indexes 0 to 7 can be grouped as one group, indexes 8 to 15 can be grouped as one group, or grouping can be performed according to the parity of the index. Different groupings of the masked sequence or mask index of the synchronization signal can indicate different detection modes of the terminal device for the target signal. By obtaining the grouping of the masked sequence or mask index of the synchronization signal, the terminal device can determine whether to detect the target signal in a continuous mode or a periodic mode.

[0128] Optionally, the first characteristic may include a 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 based on the transmission symbol index of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0129] For example, the continuous monitoring mode or the periodic detection mode can be implicitly indicated according to a preset rule based on the transmission symbol index of the synchronization signal. For example, the indication can be based on the size of the index relative to a preset value, or based on the parity of the index. When the synchronization signal is a plurality of 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.

[0130] In one 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 used for at least coarse time synchronization and coarse frequency 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 characteristic of indicating the first information. This application does not limit the name of the low power synchronization signal.

[0131] Optionally, the second characteristic may include the group to which the LP-SS sequence belongs. That is, the first information may be indicated by the group to which the LP-SS sequence belongs. In other words, the terminal device may obtain the first information based on the group to which the LP-SS sequence belongs, thereby determining a detection mode for the target signal. This application does not limit the specific grouping method.

[0132] For example, LP-SS sequences can be grouped according to their indexes according to a preset rule. For example, LP-SS sequences can be grouped according to the size of the index, or according to the parity of the index. Different LP-SS groupings can indicate different detection modes for target signals by the terminal device. The terminal device can detect the LP-SS sequence by detecting the group to which it belongs, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0133] Optionally, the second characteristic may include an LP-SS encoding scheme, that is, the first information may be indicated by the LP-SS encoding scheme. In other words, the terminal device may obtain the first information based on the LP-SS encoding scheme to determine the detection mode for the target signal. This application does not limit the specific encoding scheme.

[0134] For example, LP-SS can be source encoded or channel encoded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0135] For example, the LP-SS can be linearly coded or convolutionally coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0136] For example, according to preset rules, the LP-SS can be polarized (Polar) coded or low-density parity check (LDPC) coded, so that the terminal device can obtain the first information according to the encoding method, and determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0137] Optionally, the second characteristic may include an LP-SS scrambling method, that is, the first information may be indicated by the LP-SS scrambling method. In other words, the terminal device may obtain the first information based on the LP-SS scrambling method to determine the detection mode for the target signal. This application does not limit the specific scrambling method.

[0138] For example, the LP-SS can be encrypted with different specific sequences (for example, a PN sequence or an m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0139] For example, the first information can be obtained according to a preset rule based on the index of the sequence used to scramble the LP-SS signal. For example, the signals can be grouped based on the size of the scrambling sequence index or the parity of the scrambling sequence index. Different groups can indicate different detection modes for the target signal used by the terminal device. The terminal device can detect the LP-SS signal and determine the group to which the scrambling sequence of the synchronization signal belongs, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0140] Optionally, the second characteristic may include an LP-SS masking method. That is, the first information may be indicated by the LP-SS masking method. In other words, the terminal device may obtain the first information based on the LP-SS masking method to determine the detection mode for the target signal. This application does not limit the specific masking method.

[0141] For example, the LP-SS can be masked with different specific masking sequences (for example, a PN sequence or an m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0142] For example, the first information can be obtained according to a preset rule based on the index of the sequence or mask used to mask the LP-SS. For example, grouping can be performed based on the size of the index of the masked sequence or mask, or based on the parity of the index of the masked sequence or mask. Different groups can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the masked sequence or mask of the LP-SS belongs by detecting the LP-SS, thereby determining whether to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masked sequence or mask can be 0 to 15. Grouping can be performed based on the size of the index, with indexes 0 to 7 as one group and indexes 8 to 15 as one group, or grouping can be performed based on the parity of the index. Different groupings of the masked sequence or mask index of the LP-SS can indicate different detection modes of the terminal device for the target signal. By obtaining the grouping of the masked sequence or mask index of the LP-SS, the terminal device can determine whether to detect the target signal in a continuous mode or a periodic mode.

[0143] Optionally, the second characteristic may include an LP-SS transmission symbol index, that is, the first information may be indicated by the LP-SS transmission symbol index. In other words, the terminal device may obtain the first information based on the LP-SS transmission symbol index to determine the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0144] For example, the continuous monitoring mode or the periodic detection mode can be implicitly indicated based on the LP-SS transmitted symbol index according to a preset rule. For example, the indication can be based on the magnitude of the index relative to a preset value, or based on the parity of the index. When the LP-SS transmits multiple consecutive symbols, the indication can be based on the index of the first transmitted symbol. The terminal device can obtain first information based on the LP-SS transmitted symbol index and determine whether to detect the target signal in the continuous mode or the periodic mode.

[0145] In a possible implementation manner, the first information is allowed to be carried in a broadcast message, a SIB message, a public control message, a DCI, an RRC message, a MACCE message, or any suitable control message, which is not limited here.

[0146] In one possible implementation, the network device sends 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.

[0147] Specifically, the terminal device may send auxiliary information to the network device to assist the network device in determining the transmission method of the target signal and instruct the terminal device so that the terminal device detects the target signal in a corresponding detection mode.

[0148] 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 capability of the terminal device, including but not limited to the detection mode supported by the terminal device (for example, continuous monitoring, or periodic detection, etc.), or the modulation method of the target signal supported by the terminal device (for example, OOK, FSK or ASK, etc.).

[0149] Optionally, the auxiliary information may include third information, which may also be described as the expectation of the terminal device, for the terminal device to report the detection mode (for example, continuous monitoring, or periodic detection, etc.) expected to be adopted for performing signal detection operations on the target signal.

[0150] The third information may be determined by the terminal device based on service requirements and / or device status.

[0151] For example, the terminal device may report third information that it expects to use a continuous detection mode to detect the target signal based on the high latency requirement of the service.

[0152] For example, the terminal device may report third information that it expects to use a periodic detection mode to detect the target signal based on the fact that the service has low latency requirements and / or the terminal device has insufficient power and / or the terminal device has entered a low power consumption mode.

[0153] In response to receiving the auxiliary information from the terminal device, the network device may feed back a response message to the terminal device based on the terminal device capability and / or the detection mode desired by the terminal device to send the first information.

[0154] S202. The terminal device obtains first information and determines a detection mode for the target signal based on the first information.

[0155] The detection mode may include a continuous detection mode or a periodic detection mode.

[0156] In one possible implementation, the terminal device may support two or more detection modes for the target signal. For example, the detection mode may include a continuous detection mode and / or a periodic detection mode. Corresponding to the signal detection mode supported by the terminal device, the network device may correspondingly support two or more transmission modes for the target signal.

[0157] The network device may send first information to the terminal device according to service requirements to instruct the terminal device to adopt an appropriate detection mode to detect the target signal.

[0158] For example, if the service requires low latency, the network device can instruct the terminal device to use a continuous detection mode to detect the target signal to reduce latency.

[0159] For example, if the service does not require high latency but hopes that the terminal device can save energy, the network device can instruct the terminal device to use a periodic detection mode to detect the target signal to reduce power consumption.

[0160] After obtaining the first information, the terminal device can determine the detection mode for the target signal according to the instruction of the first information.

[0161] In a possible implementation, the target signal may be an LP-WUS. When the MR of the terminal device is in any sleep state, the LP-WUR of the terminal device may monitor and detect the LP-WUS to determine whether to wake up the MR.

[0162] In a possible implementation, the target signal may include a sequence, such as an m-sequence, a PN sequence, a Zadoff-Chu sequence, or any other suitable sequence, which is not limited here.

[0163] In a possible implementation, the target signal may include bit information. For example, the target signal may be a code or a bitmap having 8 bits, 16 bits, or any other suitable number of bits, which is not limited here.

[0164] In a possible implementation manner, the target signal may have a first format or a second format, wherein the first format and the second format are different.

[0165] Optionally, when the target signal includes a sequence, the length of the first format may be smaller than the length of the second format.

[0166] For example, the length of the sequence in the first format may be less than (or less than or equal to) the first preset length threshold, the length of the sequence in the second format may be greater than or equal to (or greater than) the second preset length threshold, and the first preset length threshold may be less than or equal to the second preset length threshold.

[0167] 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.

[0168] Optionally, when the target signal includes a presequence, the length of the first format may be greater than the length of the second format.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] For example, the number of bits of the bit information in the first format may be less than (or less than or equal to) the 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) the 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.

[0173] For example, the content carried by the target signal in the first format may be the 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 suitable information such as cell information, which is not limited here.

[0174] 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.

[0175] For example, the number of bits of the bit information in the first format may be greater than (or greater than or equal to) the 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) the 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 target signal in the first format carries more content than the content carried by the target signal in the second format.

[0176] 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 suitable information such as cell information; and the content carried by the target signal in the second format may be a UE group ID, which is not limited here.

[0177] In a possible implementation, the continuous detection mode may be used to detect a target signal having a first format.

[0178] For example, since the LP-WUR of the terminal device using the continuous detection mode is always in the on state, it can always keep monitoring and / or detecting the LP-WUS. Therefore, the LP-WUS can use a shorter sequence or bit information with fewer bits to reduce the overhead of the communication system.

[0179] In a possible implementation, the periodic detection mode may be used to detect a target signal having the second format.

[0180] For example, since the LP-WUR of the terminal device using the periodic detection mode is in an alternating on / off state, the LP-WUS can use a longer sequence or bit information with a larger number of bits to ensure that the LP-WUS can be detected when the LP-WUR is in the on state.

[0181] The first information acquired by the terminal device includes instruction information instructing the terminal device to adopt an appropriate detection mode to detect the target signal. Generally speaking, the instruction information may include an explicit instruction or an implicit instruction. The terminal device may determine the detection mode for detecting the target information based on the explicit instruction information or the implicit instruction information.

[0182] In a possible implementation, the first information may include first indication information, where 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.

[0183] For example, the first information sent by the network device to the terminal device may include first indication information (the first indication information may be called mode indication information) to instruct the terminal device to detect the target signal using a continuous detection mode or a periodic detection mode.

[0184] In a possible implementation, the first information may include second indication information, where the second indication information is used to indicate that the target signal of the terminal device has the first format or the second format.

[0185] For example, when a continuous detection mode is pre-configured for detecting a target signal having a first format, and a periodic detection mode is pre-configured for detecting a target signal having a second format, the first information sent by the network device to the terminal device may include second indication information (the second indication information may be called format indication information), which indicates the format of the target signal (i.e., the first format or the second format) to instruct the terminal device to use a continuous detection mode or a periodic detection mode to detect the target signal.

[0186] In a possible implementation manner, the network device may send a synchronization signal to the terminal device to send the first information, where the synchronization signal has a first characteristic indicating the first information.

[0187] 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 based on the group to which the sequence of synchronization signals belongs, thereby determining a detection mode for the target signal. This application does not limit the specific grouping method.

[0188] For example, the sequence of synchronization signals can be grouped according to the index of the sequence of synchronization signals according to a preset rule. For example, the sequence of synchronization signals can be grouped according to the size of the index, or according to the parity of the index. Different groupings of synchronization signals can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the sequence of synchronization signals belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0189] Optionally, the first characteristic may include an encoding method of the synchronization signal, that is, the first information may be indicated by the encoding method of the synchronization signal. In other words, the terminal device may obtain the first information based on the encoding method of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific encoding method.

[0190] For example, the synchronization signal can be source encoded or channel encoded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0191] For example, the synchronization signal can be linearly coded or convolutionally coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0192] For example, the synchronization signal can be polarization coded or LDPC coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, and determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0193] Optionally, the first characteristic may include a 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 based on the scrambling method of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific scrambling method.

[0194] For example, the synchronization signal can be encrypted with different specific sequences (for example, PN sequence, or m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0195] For example, the first information can be obtained according to a preset rule based on the index of the sequence used to scramble the synchronization signal. For example, grouping can be performed based on the size of the scrambling sequence index, or based on the parity of the scrambling sequence index. Different groups can indicate different detection modes for the terminal device for the target signal. The terminal device can obtain the group to which the scrambling sequence of the synchronization signal belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0196] Optionally, the first characteristic may include a synchronization signal masking method, that is, the first information may be indicated by the synchronization signal masking method. In other words, the terminal device may obtain the first information based on the synchronization signal masking method, thereby determining the detection mode for the target signal. This application does not limit the specific masking method.

[0197] For example, the synchronization signal can be masked with different specific masking sequences (for example, PN sequence, or m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0198] For example, the first information can be obtained according to the preset rules based on the index of the sequence or mask used to mask the synchronization signal. For example, grouping can be performed according to the size of the index of the masked sequence or mask, or grouping can be performed according to the parity of the index of the masked sequence or mask. Different groups can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the masked sequence or mask of the synchronization signal belongs by detecting the synchronization signal, thereby determining whether to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masked sequence or mask can be 0 to 15, and grouping can be performed according to the size of the index, so that indexes 0 to 7 can be grouped as one group, indexes 8 to 15 can be grouped as one group, or grouping can be performed according to the parity of the index. Different groupings of the masked sequence or mask index of the synchronization signal can indicate different detection modes of the terminal device for the target signal. By obtaining the grouping of the masked sequence or mask index of the synchronization signal, the terminal device can determine whether to detect the target signal in a continuous mode or a periodic mode.

[0199] Optionally, the first characteristic may include a 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 based on the transmission symbol index of the synchronization signal, thereby determining the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0200] For example, the continuous monitoring mode or the periodic detection mode can be implicitly indicated according to a preset rule based on the transmission symbol index of the synchronization signal. For example, the indication can be based on the size of the index relative to a preset value, or based on the parity of the index. When the synchronization signal is a plurality of 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.

[0201] In one 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 used for at least coarse time synchronization and coarse frequency 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 characteristic of indicating the first information. This application does not limit the name of the low power synchronization signal.

[0202] Optionally, the second characteristic may include the group to which the LP-SS sequence belongs. That is, the first information may be indicated by the group to which the LP-SS sequence belongs. In other words, the terminal device may obtain the first information based on the group to which the LP-SS sequence belongs, thereby determining a detection mode for the target signal. This application does not limit the specific grouping method.

[0203] For example, LP-SS sequences can be grouped according to their indexes according to a preset rule. For example, LP-SS sequences can be grouped according to the size of the index, or according to the parity of the index. Different LP-SS groupings can indicate different detection modes for target signals by the terminal device. The terminal device can detect the LP-SS sequence by detecting the group to which it belongs, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0204] Optionally, the second characteristic may include an LP-SS encoding scheme, that is, the first information may be indicated by the LP-SS encoding scheme. In other words, the terminal device may obtain the first information based on the LP-SS encoding scheme to determine the detection mode for the target signal. This application does not limit the specific encoding scheme.

[0205] For example, LP-SS can be source encoded or channel encoded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0206] For example, the LP-SS can be linearly coded or convolutionally coded according to preset rules, so that the terminal device can obtain the first information according to the encoding method, determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0207] For example, according to preset rules, the LP-SS can be polarized (Polar) coded or low-density parity check (LDPC) coded, so that the terminal device can obtain the first information according to the encoding method, and determine whether to detect the target signal in a continuous mode or a periodic mode, or determine whether to detect the target signal in a periodic mode or a continuous mode.

[0208] Optionally, the second characteristic may include an LP-SS scrambling method, that is, the first information may be indicated by the LP-SS scrambling method. In other words, the terminal device may obtain the first information based on the LP-SS scrambling method to determine the detection mode for the target signal. This application does not limit the specific scrambling method.

[0209] For example, the LP-SS can be encrypted with different specific sequences (for example, a PN sequence or an m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0210] For example, the first information can be obtained according to a preset rule based on the index of the sequence used to scramble the LP-SS signal. For example, the signals can be grouped based on the size of the scrambling sequence index or the parity of the scrambling sequence index. Different groups can indicate different detection modes for the target signal used by the terminal device. The terminal device can detect the LP-SS signal and determine the group to which the scrambling sequence of the synchronization signal belongs, thereby determining whether to detect the target signal in a continuous mode or a periodic mode.

[0211] Optionally, the second characteristic may include an LP-SS masking method. That is, the first information may be indicated by the LP-SS masking method. In other words, the terminal device may obtain the first information based on the LP-SS masking method to determine the detection mode for the target signal. This application does not limit the specific masking method.

[0212] For example, the LP-SS can be masked with different specific masking sequences (for example, a PN sequence or an m sequence) according to preset rules. 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 whether to detect the target signal in a continuous mode or a periodic mode.

[0213] For example, the first information can be obtained according to a preset rule based on the index of the sequence or mask used to mask the LP-SS. For example, grouping can be performed based on the size of the index of the masked sequence or mask, or based on the parity of the index of the masked sequence or mask. Different groups can indicate different detection modes of the terminal device for the target signal. The terminal device can obtain the group to which the masked sequence or mask of the LP-SS belongs by detecting the LP-SS, thereby determining whether to detect the target signal in a continuous mode or a periodic mode. For example, the index of the masked sequence or mask can be 0 to 15. Grouping can be performed based on the size of the index, with indexes 0 to 7 as one group and indexes 8 to 15 as one group, or grouping can be performed based on the parity of the index. Different groupings of the masked sequence or mask index of the LP-SS can indicate different detection modes of the terminal device for the target signal. By obtaining the grouping of the masked sequence or mask index of the LP-SS, the terminal device can determine whether to detect the target signal in a continuous mode or a periodic mode.

[0214] Optionally, the second characteristic may include an LP-SS transmission symbol index, that is, the first information may be indicated by the LP-SS transmission symbol index. In other words, the terminal device may obtain the first information based on the LP-SS transmission symbol index to determine the detection mode for the target signal. This application does not limit the specific transmission symbol index.

[0215] For example, the continuous monitoring mode or the periodic detection mode can be implicitly indicated based on the LP-SS transmitted symbol index according to a preset rule. For example, the indication can be based on the magnitude of the index relative to a preset value, or based on the parity of the index. When the LP-SS transmits multiple consecutive symbols, the indication can be based on the index of the first transmitted symbol. The terminal device can obtain first information based on the LP-SS transmitted symbol index and determine whether to detect the target signal in the continuous mode or the periodic mode.

[0216] In a possible implementation manner, the first information is allowed to be carried in a broadcast message, a SIB message, a public control message, a DCI, an RRC message, a MACCE message, or any suitable control message, which is not limited here.

[0217] 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, receives a response message returned by the network device in response to the auxiliary information to obtain the first information.

[0218] Specifically, the terminal device may send auxiliary information to the network device to assist the network device in determining the transmission method of the target signal and instruct the terminal device so that the terminal device detects the target signal in a corresponding detection mode.

[0219] 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 capability of the terminal device, including but not limited to the detection mode supported by the terminal device (for example, continuous monitoring, or periodic detection, etc.), or the modulation method of the target signal supported by the terminal device (for example, OOK, FSK or ASK, etc.).

[0220] Optionally, the auxiliary information may include third information, which may also be described as the expectation of the terminal device, for the terminal device to report the detection mode (for example, continuous monitoring, or periodic detection, etc.) expected to be adopted for performing signal detection operations on the target signal.

[0221] The third information may be determined by the terminal device based on service requirements and / or device status.

[0222] For example, the terminal device may report third information that it expects to use a continuous detection mode to detect the target signal based on the high latency requirement of the service.

[0223] For example, the terminal device may report third information that it expects to use a periodic detection mode to detect the target signal based on the fact that the service has low latency requirements and / or the terminal device has insufficient power and / or the terminal device has entered a low power consumption mode.

[0224] In response to receiving the auxiliary information from the terminal device, the network device may feed back a response message to the terminal device based on the terminal device capability and / or the detection mode desired by the terminal device to send the first information.

[0225] S203. The network device sends a target signal to the terminal device.

[0226] The network device sends the first information to the terminal device, instructing the terminal device to determine the detection mode for the target signal, and then send the target signal in the form of the target signal corresponding to the detection mode indicated to the terminal device (for example, the format, length or carried content of the target signal, etc.).

[0227] Specifically, the network device may send first information to the terminal device in an explicit or implicit manner, indicating 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 indicated detection mode and the corresponding target signal form (e.g., the format, length, or content carried by the target signal). The correspondence between the detection mode and the target signal form can be referred to the relevant description in S201 and will not be repeated here.

[0228] In a possible implementation, when the detection mode indicated by the first 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.

[0229] Optionally, the configured time interval may include a pre-configured time interval. The pre-configured time interval may be specified by a protocol, or may be indicated by a higher layer signaling, or may be pre-configured in any other appropriate manner.

[0230] Optionally, the configured time interval may further include the time interval indicated by the first information. The first information indicates that the detection mode is the continuous detection mode and may also indicate a time interval for detecting the target signal.

[0231] In one possible implementation, 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, i.e., the network device repeatedly sends the target signal to the terminal device at least twice.

[0232] In one possible implementation, 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, i.e., the network device does not repeatedly send the target signal to the terminal device.

[0233] S204. The terminal device performs signal detection on the target signal based on the determined detection mode.

[0234] 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 from the network device in a form corresponding to the determined detection mode (for example, the format, length or carried content of the target signal, etc.) based on the determined detection mode.

[0235] Specifically, the terminal device may obtain first information sent to the terminal device by the network device in an explicit or implicit manner, and determine a detection mode to be adopted for the target signal based on the first information, and perform signal detection on the target signal from the network device in a 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 be referred to the relevant description in S202 and will not be repeated here.

[0236] In one possible implementation, when the determined detection mode is a continuous detection mode, the terminal device performs signal detection on the target signal from the network device based on the determined detection mode, which may include: performing signal detection on the target signal from the network device within a configured time interval.

[0237] Optionally, the configured time interval may include a pre-configured time interval. The pre-configured time interval may be specified by a protocol, or may be indicated by a higher layer signaling, or may be pre-configured in any other appropriate manner.

[0238] 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 detect the target signal within the time interval indicated by the first information.

[0239] In one 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 target signal repeatedly transmitted 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, i.e., the network device repeatedly transmits the target signal to the terminal device at least twice.

[0240] In one 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 target signal repeatedly transmitted 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, i.e., the network device does not repeatedly transmit the target signal to the terminal device.

[0241] In the method described in Figure 2, the network device sends first information to the terminal device, the terminal device obtains the first information, and determines a detection mode for the target signal based on the first information, where 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. Because the network device can instruct the terminal device on the detection mode to be used for the target signal based on business needs, it can be applied to different application scenarios, facilitates determining the appropriate signal detection mode based on business needs, and can balance system latency and energy efficiency.
