Description

Communication method and apparatus

[0001] This application claims priority to the Chinese Patent Application No. 202411399843.3, filed on September 30, 2024, entitled “Communication method and apparatus”, the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method and apparatus. BACKGROUND

[0003] To reduce the power consumption of terminal devices, low power wake-up signal (LP-WUS) / low power wake-up receiver (LP-WUR) is introduced in 3rd generation partnership project (3GPP) release (R) 18 / 19.

[0004] When the main receiver (MR) of the terminal device is in deep sleep or ultra-deep sleep, only one LP-WUR with ultra-low power is turned on to listen to the LP-WUS at the LP-WUS occasion (LO), one LO includes one or more LP-WUS monitoring occasion (MO) groups, each LP-WUS MO group includes multiple LP-WUS MOs for transmitting the same LP-WUR in different beam directions, the LP-WUR will trigger the MR to wake up or start, the MR will switch from deep sleep or ultra-deep sleep back to active state, and detect paging downlink control information (DCI) (paging DCI) at the paging occasion (PO) in the paging frame (PF) to determine whether the network device has sent a paging message. In this process, the LP-WUR needs a certain operation processing time from receiving the LP-WUS to the MR being able to receive the paging, which is generally referred to as transition time.

[0005] In the above process, the network device also periodically sends a synchronization signal (low power synchronization signal, LP-SS), which is used by the LP-WUR for time synchronization and frequency synchronization. The transmission period of the LP-SS is usually 320 ms, and the transmission time of the LP-SS is independent of the PF / PO configured by the cell. The specific time position of the LO is related to the time position at which the terminal device needs to detect the PF / PO. For example, if the starting time of the PF / PO is T p , the starting time of the LO is T p -LO offset time (LO-offset), which is greater than the conversion time described above. Therefore, if the LP-SS is transmitted at a predetermined period, the transmission time of the LP-SS may conflict with the transmission time of the LO. Therefore, how to solve the transmission mode of the LP-WUS when the transmission time of the LP-SS conflicts with the transmission time of the LO is an urgent problem to be solved. SUMMARY

[0006] The present application provides a communication method and device, which defines a transmission mode of the LP-WUS when the transmission time of the LP-SS conflicts with the transmission time of the LO, so as to avoid signal conflict between the LP-SS and the LP-WUS.

[0007] To achieve the above object, the present application adopts the following technical solutions:

[0069] In order to better understand the embodiments of the present application, the following points are explained before the embodiments of the present application are introduced.

[0070] First, in the embodiments of the present application, the first, second and various numbers are only for the convenience of description and do not limit the scope of the embodiments of the present application. For example, the first terminal device and the second terminal device distinguish different terminal devices, and do not limit the order. Those skilled in the art can understand that the words "first", "second" and the like do not limit the number and execution order, and the words "first", "second" and the like do not necessarily mean different.

[0071] Second, in the embodiments of the present application, the descriptions such as "when", "in the case of", "if" and "if" all refer to the objective situation that the device (such as a terminal device or a network device) will make corresponding processing, not limited to time, and does not require the device (such as a terminal device or a network device) to have a judgment action when implemented, nor does it mean that there are other limitations.

[0072] Third, in the embodiments of the present application, the words "exemplary" or "for example" are used to indicate an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words "exemplary" or "for example" are intended to present the relevant concept in a specific manner, and to facilitate understanding.

[0073] Fourth, in the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of multiple items, including any combination of single item or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0074] Finally, the network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0075] The embodiments of the present application will present various aspects, embodiments or features around a system that can include multiple devices, components, modules, etc. It should be understood and appreciated that each system can include additional devices, components, modules, etc., and / or can not include all the devices, components, modules, etc. discussed in conjunction with the drawings. In addition, combinations of these solutions can also be used.

[0076] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems such as long term evolution (LTE) systems, worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems such as NR systems, and future communication systems.

[0077] Please refer to FIG. 1, which is a schematic diagram of a possible and non-restrictive communication system. As shown in FIG. 1, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 can also include the Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0078] The RAN 100 can be a 3GPP related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolved system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a Wi-Fi system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0079] The RAN node 110, which can also be referred to as a network device, an access network device, a RAN entity, or an access node, etc., constitutes a part of the communication system to help the terminal to realize wireless access. The multiple RAN nodes 110 in the communication system 1000 can be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, the network element 120i in FIG. 1 can be a helicopter or a drone, which can be configured as a mobile base station. For those terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication apparatuses, for example, the network elements 110a and 110b in FIG. 1 can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0080] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a Wi-Fi system, etc. The RAN node can be a macro base station (such as 110a in FIG. 1), a micro base station or an indoor station (such as 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in the V2X technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node can also be provided with a communication module, circuit or chip for performing corresponding communication functions, and program instructions for performing corresponding communication functions. The RAN node in this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0081] In another possible scenario, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0082] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the O-RAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0083] A terminal can access the above-mentioned communication system and has corresponding communication functions. The terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, such as D2D, V2X communication, machine-type communication (MTC), internet of things (IoT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, a transport vehicle with wireless communication function, a communication module, etc. Embodiments of the present application do not limit the device form of the terminal. The terminal is usually provided with a communication module, circuit or chip for executing corresponding communication functions. The terminal is also configured with program instructions for executing corresponding communication functions.

[0084] It should be pointed out that the scheme in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of the corresponding functions in other communication systems. In this application, the RAN node is expressed as a network device and the terminal is expressed as a terminal device unless otherwise specified.

[0085] It should be understood that in the embodiments of the present application, the names of the nodes, modules, devices or network elements in different scenarios or architectures or systems, and the names of the communication interfaces between the nodes, modules, devices or network elements are exemplarily given, and the possibility of name changes in future communication systems or scenarios or architectures is not excluded.

[0086] The following introduces the related terms or technologies involved in the embodiments of the present application.

[0087] Compared with LTE, NR supports a larger transmission bandwidth, more antenna arrays, higher transmission rates, and more flexible and smaller-granularity scheduling mechanisms. The above characteristics of NR provide more application scope, but greatly increase the power consumption burden of terminal devices. To reduce the power consumption of terminal devices, 3GPP introduced the LP-WUS / WUR research topic in R18 / R19, which aims to study possible power reduction schemes for terminal devices in various states, including connected state, idle state, and inactive state.

[0088] I. Wakeup Radio (WUR)

[0089] The concept of wakeup radio refers to the terminal device starting only an LP-WUR to listen to a wakeup packet when the MR is in deep sleep, and the wakeup packet generally carries an LP-WUS used to wake up the MR. The working state of the LP-WUR is shown in FIG. 2, and the two states are:

[0090] State 1: After the MR completes data transmission and reception and returns to the idle state, the MR can enter a deep sleep state or an ultra-deep sleep state or even be completely turned off to reduce power consumption. At this time, the LP-WUR of the terminal device is in a powered-on (or on) state and receives the LP-WUS.

[0091] State 2: Once the LP-WUR receives an LP-WUS sent to itself or a group to which it belongs, the LP-WUR will trigger the MR to wake up or turn on, and the MR will continue to transmit and receive data or signaling.

[0092] The MR can also be referred to as a main radio, a communication main module, a main circuit, etc., which is a traditional receiver of an NR terminal device, used to receive NR downlink signaling, signals, and data, etc. The wakeup receiver is an LP-WUR, which can also be referred to as a wakeup circuit, a communication auxiliary module, an auxiliary circuit, etc. The MR includes a radio frequency module and a baseband processing module, while the LP-WUR can include only a simple receiver composed of a radio frequency module, or a lower-power module (the rate and bandwidth of the LP-WUS are much lower than those of the usual NR data), which makes the working power consumption of the LP-WUR much lower than that of the MR, for example, the working state power consumption of the LP-WUR is less than one-tenth of the average power consumption of the MR in idle mode.

[0093] The LP-WUR can be using some radio frequency circuitry and baseband circuitry with lower power consumption, for example, the LP-WUR can not include a mixer, or use a mixer using a low-power ring oscillator to replace a phase lock loop (PLL), use a low noise amplifier (LNA) with a higher noise figure, etc. The LP-WUR can also be a sub-module (i.e., partial module) of the MR, or multiplex some circuitry, devices, etc. with the MR. Alternatively, the LP-WUR includes fewer devices when operating than the MR, for example, the LP-WUR does not include a fast Fourier transform module, a complex channel decoding module, a low density parity check code (LDPC) decoding module, and a polar decoding module, etc., and can have fewer registers and memory units, use a lower bandwidth bus, and thus has lower power consumption than the MR. Alternatively, the MR in a low-power mode of operation can also be considered as an LP-WUR, for example, when the MR reduces the operating voltage, turns off some high-power functions, slows down the clock frequency, or reduces the sampling rate and bit width of the analog-to-digital sampling, it is an LP-WUR.

[0094] The LP-WUR system can include the following two signals:

[0095] (1) LP-SS: The LP-SS can be transmitted periodically or aperiodically, and mainly provides time synchronization for the LP-WUR, facilitating determination of whether the frame, subframe, time slot, orthogonal frequency division multiplexing (OFDM) symbol (hereinafter referred to as symbol) in which the LP-WUR is currently located is within the coverage of the cell, and whether the local clock has deviated. The LP-SS can also provide frequency synchronization, so that the terminal device determines whether its operating frequency deviates from the transmission frequency of the LP-WUS; in addition, the LP-SS can also carry the identifier of the cell, used to distinguish different cells accessed by the LP-SS. The LP-SS is transmitted through different beams (beams), used to cover different area directions of the cell, as shown in FIG. 3, the LP-SS is transmitted on beam 1 to beam 4. It should be understood that different beams do not necessarily need to be continuous in time.

[0096] (2) LP-WUS: used to indicate whether a specific terminal device or a group of terminal devices is woken up. When the terminal device or the group of terminal devices is woken up, the LP-WUS triggers the terminal device in the terminal device or the group of terminal devices to wake up the MR to perform some operations, including but not limited to updating system messages, receiving paging messages, initiating random access, receiving disaster warning information, etc.

[0097] In some possible designs, due to a long transmission period of the LP-SS, for example, 320 milliseconds (ms), a time interval from receiving the LP-SS to receiving the LP-WUS signal is large, and a clock and a frequency are offset again at a time of receiving the LP-WUS, which causes a decline in LP-WUS receiving performance. To this end, the network device can further transmit a preamble before transmitting the LP-WUS signal, as shown in FIG. 4. The preamble can be used for the terminal device to perform time-frequency synchronization before receiving the corresponding LP-WUS, to improve receiving performance.

[0098] II. Workflow of the LP-WUR wake-up MR

[0099] The workflow of the LP-WUR wake-up MR is as follows:

[0100] 1. When the terminal device receives the LP-WUS using the LP-WUR, the MR is generally in a low-power state, for example, deep sleep or ultra-deep sleep.

[0101] 2. When the LP-WUR receives the LP-WUS, the terminal device first needs to process the received signal, for example, to complete demodulation and decoding (if the LP-WUS signal is channel coded) of the received signal, to perform parity check (if the LP-WUS exists in a case of a check code) on the decoded signal, and to identify wake-up information.

[0102] 3. If the terminal device identifies that the LP-WUS contains wake-up information of the terminal device or a user group to which the terminal device belongs, the LP-WUR sends a wake-up indication to the MR, to trigger the MR to wake up.

[0103] 4. The MR switches from deep sleep or ultra-deep sleep back to an active state, and the main process can include:

[0104] a) The MR chip, antenna, storage, and other peripheral devices are powered on and started;

[0105] b) The MR chip, antenna, storage, and other peripheral devices load pre-stored configuration parameters from a read-only memory (ROM) chip;

[0106] c) The MR searches for a network, and determines a serving cell in which the terminal device is currently located;

[0107] d) MR further performs fine time-frequency synchronization to determine the time boundary of the serving cell (frame structure, subframe, time slot, and symbol, etc.).

[0108] 5) MR receives the paging when the paging time arrives, and performs corresponding operations according to the paging indication.

[0109] It can be seen that, from receiving the LP-WUS to the MR being able to receive the paging, a certain operation processing time is required, which is generally referred to as transition time.

[0110] III. Paging mechanism

[0111] Paging also refers to a paging message, which is used for the network to trigger the terminal device to establish a radio resource control (RRC) connection, or to notify the terminal device of system information update, and to send an earthquake and tsunami warning. The content of the paging message is sent to the terminal device through a physical downlink shared channel (PDSCH), and the PDSCH is scheduled by a PDCCH scrambled by a paging radio network temporary identifier (P-RNTI).

[0112] The process for the terminal device to acquire the paging message is as follows: the terminal device in an idle state or an inactive state is periodically woken up, and after the terminal device is woken up, the PDCCH scrambled by the P-RNTI is monitored, and the position (for example, time-frequency position) information of the PDSCH in the DCI in the PDCCH is analyzed. The terminal device receives the PDSCH according to the position information of the PDSCH, and acquires the paging message in the PDSCH. The terminal device determines whether the paging message includes its own terminal device identifier. If yes, the terminal device performs corresponding operations (for example, establishing an RRC connection; or returning from the inactive state to the idle state, etc.).

[0113] The specific time for the terminal device to receive the paging is defined by the PF and the PO.

[0114] (1) PF: indicates a radio frame in which a paging is sent, i.e., a terminal device in an idle state and an inactive state only receives a paging attempt in a PF, and a length of one radio frame in an NR system is 10 ms. The terminal device can determine whether a radio frame is a PF according to the following formula: when a system frame number (SFN) of the radio frame satisfies the following relationship, the radio frame is considered to be a PF: (SNF+PF_offset)mod T=(T / N)×(UE_ID mod N).

[0115] wherein SFN is a system frame number of a current radio frame; PF_offset is a frame offset of the PF; T is a discontinuous reception (DRX) cycle, which is a time unit, and can be understood as that the terminal device can have one attempt to receive a paging in one time T, and the DRX cycle in the NR system can be 1280 ms, 2560 ms, etc.; N is a number of PFs included in each DRX cycle; and UE_ID is an identifier of the terminal device, which can be a 5th generation system architecture evolution temporary mobile station identifier (5G-S-TMSI Identifier) mod 1024 or a full inactive radio network temporary identifier (full I-RNTI).

[0116] (2) PO: indicates an occasion of attempting to receive a paging in one PF, and for each PF, there can be a plurality of POs. The NR adopts a parameter N s to indicate a number of POs corresponding to one PF, N s = 1, 2, 4. Each PO has an index number i_s, which is determined by the following formula: i_s=floor(UE_ID / N)mod N s .

[0117] wherein floor(·) is a floor function.

[0118] It should be noted that the network device does not send a paging message to the terminal device at each PO, and the terminal device detects a paging DCI at the PO to determine whether the network device has sent a paging message.

[0119] Four, sending occasion of LP-WUS

[0120] The transmission occasion of the LP-WUS (which can correspond to a monitoring occasion on the terminal device side) is defined as an LP-WUS monitoring occasion (LP-WUS MO). The LP-WUS MO can be understood as a period of time, frequency resource, and occasion that is predefined or configured by the network, and the network can or can not transmit the LP-WUS in the LP-WUS MO. The LP-WUS MOs configured by the network for different terminal devices or groups of terminal devices can be different, and can be distinguished by the period of the LP-WUS MO and the transmission time within the period.

[0121] Generally, the period of the LP-WUS MO is the same as or a multiple of the DRX period. Since the network can transmit signals using different beams, the same LP-WUS can be transmitted through multiple LP-WUS MOs, where the beam direction transmitted by each LP-WUS MO is different (the information transmitted is exactly the same). As shown in FIG. 5, the LP-WUS signal uses 4 LP-WUS MOs to transmit 4 beam directions, which are used to cover terminal devices at different locations in the cell.

[0122] Generally, the number of beams transmitted by the LP-WUS and the transmission direction of each beam correspond one-to-one to the number of beams of the synchronization signal (including the SSB of NR or LP-SS) of the cell and the transmission direction of each beam.

[0123] In FIG. 5, one LP-WUS MO is configured for each beam direction to transmit the LP-WUS once, while in an actual system, more than one LP-WUS MO can be configured for the same beam direction to transmit the same LP-WUS information repeatedly to improve the reliability of reception. As shown in FIG. 6, each beam direction has two LP-WUS MOs, i.e., the LP-WUS is transmitted twice repeatedly in the same beam direction, so the entire LP-WUS occupies 8 LP-WUS MOs, which can be referred to as an LP-WUS MO group.

[0124] It should be understood that in FIG. 6, the LP-WUS is repeatedly transmitted for each beam first, and then different beams are transmitted, and in an actual system, different beams can be transmitted first and then repeated, and no limitation is made in this regard.

[0125] It should also be understood that the multiple LP-WUS MOs in one LP-WUS MO group shown in FIG. 6 are connected head to tail with each other, i.e., consecutive in time and frequency domain, and in actual systems, the multiple LP-WUS MOs in one LP-WUS MO group can be spaced, i.e., discontinuous, in time and frequency, and no limitation is made thereto.

[0126] The LP-WUS transmitted in each LP-WUS MO can carry M (M is a positive integer) bits of wake-up information, which can wake up one of multiple different terminal devices or one of a terminal device group, or simultaneously wake up multiple terminal devices or terminal device groups. Therefore, multiple terminal devices and terminal device groups can also monitor the same LP-WUS, which is transmitted in one LP-WUS MO group. That is, the MOs in one LP-WUS MO group are generally used to transmit the same LP-WUS.

[0127] In some designs, the terminal devices monitoring the same PO can be divided into multiple different terminal device groups, which are generally referred to as sub-groups. One LP-WUS can indicate all sub-groups in one PO (i.e., the same LP-WUS can be used to wake up terminal devices in all sub-groups monitoring the same PO), can indicate multiple sub-groups in multiple POs (i.e., the same LP-WUS can be used to wake up terminal devices in multiple sub-groups monitoring different POs), or can indicate different sub-groups in one PO (i.e., the same LP-WUS can be used to wake up terminal devices in multiple sub-groups monitoring the same PO), and no limitation is made thereto.

[0128] In the idle state, one or more LP-WUS MO groups can be combined into one LP-WUS occasion (LO), i.e., one LO can contain one or more LP-WUS MO groups, which can correspond to different sub-groups in one or more POs. As shown in FIG. 7, one LO includes 4 LP-WUS MO groups (each LP-WUS MO group can include multiple LP-WUS MOs, multiple beams are transmitted and repeated), and each LP-WUS MO group transmits different LP-WUS for waking up different sub-groups. For terminal devices in one sub-group, the corresponding LP-WUS can be transmitted in any one of the 4 LP-WUS MO groups.

[0129] It should be understood that the multiple LP-WUS MO groups can be consecutive or discontinuous in time and frequency, and no limitation is made thereto.

[0130] Currently, the specific time position of the LO is related to the time position of the PF / PO that the terminal device needs to detect, assuming that the PO (or the PF in which the PO is located) that the MR of the terminal device needs to receive is at time T p To begin with, as introduced above, after the terminal device receives the LP-WUS on the LP-WUR, it needs to go through the processing of the transition time before sending the paging PDCCH received in the PO using the MR. For this purpose, the network device can configure the occurrence time of the LO to be T p before the LO offset time (LO-offset), as shown in FIG. 8, that is, the starting time of the LO is T p -LO-offset, which is a time offset greater than the transition time.

[0131] However, since a single LO can include multiple LP-WUS MO groups, and each LP-WUS MO group can also include multiple LP-WUS MOs, the time actually occupied by one LO can be relatively long. If the LO is set according to the time position of the corresponding PF / PO as shown in FIG. 8, and the LP-SS definition is periodically transmitted, typically with a transmission period of 320 ms, the occurrence time of which is generally unrelated to the PO / PF configured by the cell, the transmission time of the LP-SS and the LO in the time domain can conflict, resulting in signal conflict between the LP-SS and the LP-WUS. If the LP-SS and the LP-WUS are configured on the same frequency, the time conflict means that the network device can only send one kind of signal, and a rule needs to be defined to solve the conflict problem. If the LP-SS and the LO are configured on different frequencies, the LP-WUR reception capability is poor, and only one kind of signal can be received, and the reception behavior of the LP-WUR needs to be defined.

[0132] Therefore, how to solve the transmission mode of the LP-WUS when the transmission time of the LP-SS conflicts with the LO is an urgent problem to be solved. For this purpose, the embodiments of the present application provide a communication method and device, and the terminal device and the network device can perform invalidation or delay processing on the LO that conflicts with the transmission time of the LP-SS, or select the LP-WUS MO that constitutes the LO with the transmission time of the LP-SS to receive the LP-WUS.

[0133] The communication method provided by the embodiments of the present application will be described in detail below in conjunction with FIGS. 9-16.

[0134] Exemplarily, FIG. 9 is a flow diagram of a communication method provided by an embodiment of the present application, an execution subject of the communication method is a first device, which can be a network device or a chip of a network device as shown in FIG. 1, or a terminal device or a chip of a terminal device as shown in FIG. 1. For example, the method performed by the network device in the present application can also be implemented by a module (such as a circuit, a processor, a chip or a chip system, etc.) in the network device, or a logic node, a logic module or software capable of realizing all or part of the functions of the network device; the method performed by the terminal device in the present application can also be implemented by a communication module in the terminal device or a circuit or chip (such as a modem chip (also known as a baseband chip), or a SoC chip containing a modem core, or a SIP chip) responsible for communication functions in the terminal device.

[0135] As shown in FIG. 9, the communication method comprises:

[0136] S901, the first device acquires first configuration information and second configuration information.

[0137] The first device can be a terminal device or a chip of a terminal device, or a network device or a chip of a network device, which is not limited. For ease of description, the first device is taken as a terminal device or a network device in the following description.

[0138] The first configuration information is used to configure a first LO for sending a first LP-WUS, and the second configuration information is used to configure a sending time of the first signal. It can be understood that the first configuration information can be considered as information capable of configuring a time domain resource for sending the first LP-WUS, and the second configuration information can be considered as information capable of configuring a time domain resource for sending the first signal. It should be understood that the first configuration information and the second configuration information can be used to configure a frequency domain resource of a signal in addition to a time domain resource of a signal.

[0139] Optionally, the sending time of the first signal can be predefined or agreed upon by the network device and the terminal device in advance, and the network device does not need to configure it through the second configuration information, so the first device can not need to acquire the second configuration information.

[0140] The first LP-WUS is a signal used to wake up or start a terminal device, and is specifically used to indicate whether an MR of the terminal device needs to be woken up, and is received and parsed by an LP-WUR of the terminal device to obtain a wake-up signal (also referred to as wake-up information) to indicate the MR to wake up the MR. The first LP-WUS can be used to wake up one of a plurality of different terminal devices or a terminal device group, or a plurality of terminal devices or a plurality of terminal device groups, which is not limited. For specific description, reference can be made to the related description of the above-mentioned technology one and technology four, which is not described herein.

[0141] The first LO corresponds to the first PF or the first PO in which the terminal device detects the paging. The first PF is the PF in which the first PO is located, or the first PO is a PO in the first PF. The same PF or PO can be monitored by one or more terminal devices, or can be monitored by terminal devices in one or more terminal device groups, or can be monitored by one or more terminal devices in a terminal device group. The first LO corresponds to the first PF or the first PO in which the terminal device detects the paging, which can be understood as that, after the MR of the terminal device receiving the first LP-WUS on the first LO is woken up, the terminal device monitors the paging message on the first PF or the first PO. The time offset of the time domain starting position of the first LO relative to the time domain starting position of the first PF or the first PO is the above-mentioned LO time offset (LO-offset). The specific description of PF and PO can be referred to the related description in the above-mentioned technology three, and the specific description of the correspondence between LO and PF or PO can be referred to the related description in the above-mentioned technology four, which is not limited.

[0142] The first LO can include one or more LP-WUS MO groups, and each LP-WUS MO group in the one or more LP-WUS MO groups includes one or more LP-WUS MOs. The LP-WUS MOs in each LP-WUS MO group can correspond to multiple different beam directions.

[0143] The number P of LP-WUS MOs included in the first LO can satisfy the following relationship: P = M × N × K, T p1 The starting time of the first PF or the first PO in which the terminal device detects the paging is Δt, M is the number of LP-WUS MO groups in the first LO, N is the number of beam transmission directions of each LP-WUS MO group, K is the number of LP-WUS MOs corresponding to the same beam transmission direction in each LP-WUS MO group, and M, N and K are positive integers. The specific description of LO can be referred to the related description in the above-mentioned technology four, which is not repeated. It should be understood that when M = 1, i.e., the LO only includes one MO group, there can be no concept of MO group. In this case, the LO can be defined as a LO including multiple LP-WUS MOs, which is not limited.

[0144] The first LP-WUS can be sent in any LP-WUS MO group in the first LO, and different LP-WUS MO groups are used to send different LP-WUS. The terminal device receives and detects the LP-WUS sent by each LP-WUS MO group in the first LO, judges whether the wake-up information carried by the LP-WUS can wake up the terminal device, if yes, it is the first LP-WUS, otherwise, it is not the first LP-WUS.

[0145] The first signal can be a signal with a higher transmission priority than the first LP-WUS. The first signal and the first LP-WUS can be on the same frequency or have overlapping frequency and bandwidth, or can be on different frequencies or have non-overlapping frequency and bandwidth. In some possible designs, the first signal can be any one of the following: an LP-SS, a PDCCH, a TRS, or an SSB. The PDCCH, the TRS, and the SSB are control signals or control channels in an NR system, have a higher transmission priority than the LP-WUS, and are mainly used in a scenario where the NR system and the LP-WUR system share a bandwidth and signals collide. It should be understood that the first signal can be other control signals or control channels in the NR system in addition to the signals shown above, such as a channel state information-reference signal (CSI-RS), without limitation. In subsequent examples, the first signal is taken as an LP-SS for illustration.

[0146] For example, the first configuration information can include a time domain starting position of the first LO, a number of LP-WUS MO groups contained in the first LO, a time offset value of a time domain starting position of each LP-WUS MO group relative to the time domain starting position of the first LO, a number of LP-WUS MOs in each LP-WUS MO group, and the like, without limitation. The time domain starting position of the first LO can be indicated by configuring a time offset value (LO-offset) of the time domain starting position of the first LO relative to the first PF or the first PO. It can be understood that the time of configuring the first LO can refer to a time from a starting time of a first LP-WUS MO group to an ending time of a last LP-WUS MO group in the first LO.

[0147] For example, the first signal is taken as an LP-SS, the LP-SS can be periodically transmitted, and the second configuration information can include a time domain starting position of a first transmission of the LP-SS, a duration of transmitting the LP-SS, a length of a transmission cycle of the LP-SS, and the like, without limitation. The transmission time of the LP-SS can include a time from a starting time of a first beam to an ending time of a last beam when the LP-SS is transmitted once. Optionally, since the terminal device can perform certain processing and device switching (for example, switching a sampling rate of a receiver) between receiving the LP-SS and receiving the LP-WUS on the LO, the transmission time of the LP-SS can further include a GAP time before and after the actual transmission of the LP-SS. For example, the transmission time of the LP-SS includes A symbols of the actual transmission of the LP-SS, plus B1 symbols before the A symbols and B2 symbols after the A symbols, where A, B1, and B2 are positive integers.

[0148] In some scenarios, the LP-SS can also be non-periodically transmitted, and no limitation is made in this regard. In addition, the resource configuration of the other types of first signals shown above can refer to the existing related implementation, and no further description is made in this regard.

[0149] It should be understood that the embodiments of the present application exemplarily illustrate the resource configuration mode of the first LO and the LP-SS, and no limitation is made in this regard.

[0150] In the case where the first device is a terminal device, the first device obtaining the first configuration information and the second configuration information can include that the terminal device receives the first configuration information and the second configuration information from a network device. That is, the first LO and the time-frequency domain resource for transmitting the first signal are configured and issued by the network device. In the case where the first device is a network device, the first device obtaining the first configuration information and the second configuration information can include that the network device locally configures (or generates) the first configuration information and the second configuration information. After generating the first configuration information and the second configuration information, the network device transmits the first configuration information and the second configuration information to the terminal device.

[0151] Optionally, the first configuration information and the second configuration information can be transmitted separately, and no limitation is made on the order of transmission, or they can be transmitted together, and no limitation is made in this regard.

[0152] S902, the first device determines, according to the first configuration information and the second configuration information, that the first LO overlaps in time domain with the transmission time of the first signal.

[0153] After the first device obtains the first configuration information and the second configuration information, the first device can determine the time domain position of the first LO according to the first configuration information, and determine the transmission time (or time domain position) of the first signal according to the second configuration information, so as to determine whether the first LO and the first signal overlap in time domain according to the time domain position of the first LO and the transmission time of the first signal. In the case where the first LO and the transmission time of the first signal overlap in time domain (equivalent to signal transmission conflict), that is, there is overlapping time domain resource, the first device performs S903 described below.

[0154] S903, the first device invalidates the first LO, or the first device delays the first LO.

[0155] Case 1, the first device invalidates the first LO, and there are three possible design schemes as follows:

[0156] Design scheme 1, the first device invalidates the entire first LO, that is, no first LP-WUS is transmitted on each LP-WUS MO in the first LO.

[0157] If the first device is a terminal device or a chip of a terminal device, the first device determines not to receive the first LP-WUS on the first LO. Correspondingly, if the first device is a network device or a chip of a network device, the first device determines not to transmit the first LP-WUS on the first LO.

[0158] For example, as shown in FIG. 10, if the first LO overlaps with the transmission time of the LP-SS in the time domain, the network device does not transmit the first LP-WUS on any LP-WUS MO of the first LO, and correspondingly, the terminal device does not detect the first LP-WUS on any LP-WUS MO of the first LO.

[0159] In design scheme 2, since the first LO includes one or more LP-WUS MO groups, the first device can disable the LP-WUS MO group of the first LO that overlaps with the transmission time of the first signal, that is, the first device does not transmit the first LP-WUS on each LP-WUS MO of the LP-WUS MO group of the first LO that overlaps with the transmission time of the first signal, and transmits the first LP-WUS on each LP-WUS MO of the LP-WUS MO group of the first LO that does not overlap with the transmission time of the first signal.

[0160] If the first device is a terminal device or a chip of a terminal device, the first device determines not to receive the first LP-WUS on the first LO. Correspondingly, if the first device is a network device or a chip of a network device, the first device determines not to transmit the first LP-WUS on the first LO.

[0161] For example, as shown in FIG. 11, the first LO includes two LP-WUS MO groups, i.e., LP-WUS MO group 1 and LP-WUS MO group 2, each of which includes four LP-WUS MOs, wherein the LP-WUS MO group 1 overlaps with the transmission time of the first signal, the network device does not transmit the first LP-WUS on any LP-WUS MO of the LP-WUS MO group 1 of the first LO, and correspondingly, the terminal device does not receive the first LP-WUS on any LP-WUS MO of the LP-WUS MO group 1 of the first LO. It should be understood that for the LP-WUS MO group 2 that does not overlap with the transmission time of the LP-SS, the network device transmits the LP-WUS on each LP-WUS MO of the LP-WUS MO group 2, and correspondingly, the terminal device receives the LP-WUS on each LP-WUS MO of the LP-WUS MO group 2 and detects whether the LP-WUS is the first LP-WUS.

[0162] In the design scheme 3, since the first LO includes one or more LP-WUS MO groups, each of the one or more LP-WUS MO groups includes one or more LP-WUS MOs, the first device can invalidate the LP-WUS MOs in the first LO that overlap with the transmission time of the first signal, i.e., none of the LP-WUS MOs in the first LO that overlap with the transmission time of the first signal transmits the first LP-WUS, while the LP-WUS MOs in the first LO that do not overlap with the transmission time of the first signal transmit the first LP-WUS.

[0163] If the first device is a terminal device or a chip of a terminal device, the first device determines not to receive the first LP-WUS on the LP-WUS MOs in the first LO that overlap with the transmission time of the first signal. Correspondingly, if the first device is a network device or a chip of a network device, the first device determines not to transmit the first LP-WUS on the LP-WUS MOs in the first LO that overlap with the transmission time of the first signal.

[0164] For example, as shown in FIG. 12, the first LO includes two LP-WUS MO groups, i.e., LP-WUS MO group 1 and LP-WUS MO group 2, each of which includes four LP-WUS MOs, wherein the LP-WUS MO1 and the LP-WUS MO2 in the LP-WUS MO group 1 overlap with the transmission time of the LP-SS, so the network device does not transmit the first LP-WUS on the LP-WUS MO1 and the LP-WUS MO2 in the LP-WUS MO group 1, and correspondingly, the terminal device does not receive the first LP-WUS on the LP-WUS MO1 and the LP-WUS MO2 in the LP-WUS MO group 1.

[0165] It should be understood that for the LP-WUS MO3 and the LP-WUS MO4 in the LP-WUS MO group 1 that do not overlap with the transmission time of the LP-SS, and the LP-WUS MO group 2, the network device transmits the LP-WUS on each of the LP-WUS MO3 and the LP-WUS MO4 in the LP-WUS MO group 1, and the LP-WUS MO group 2, and correspondingly, the terminal device receives the LP-WUS on each of the LP-WUS MO3 and the LP-WUS MO4 in the LP-WUS MO group 1, and the LP-WUS MO group 2, and detects whether the LP-WUS is the first LP-WUS.

[0166] In the embodiments of the present application, the LP-WUS MO in the first LO that is invalidly processed can be referred to as an invalid MO, and the LP-WUS MO that is not invalidly processed can be referred to as a valid MO, and the valid MO can be used to transmit the LP-WUS.

[0167] In case 2, the first device delays the first LO, and there is a design scheme that the first device determines to delay the first LO to a time after the transmission time of the first signal that overlaps the first LO. That is, the first device delays the entire time domain position of the first LO to a time after the transmission time of the first signal that does not overlap, and then uses the first LO to transmit the first LP-WUS.

[0168] If the first device is a terminal device or a chip of a terminal device, the first device determines to receive the first LP-WUS on the delayed first LO. Correspondingly, if the first device is a network device or a chip of a network device, the first device determines to transmit the first LP-WUS on the delayed first LO, for example, the start time of the delayed first LO and the end time of the transmission time of the overlapping first signal are different by X time domain resources, and X is an integer greater than or equal to 0.

[0169] For example, as shown in FIG. 13, the LO offset time between the first LO and the corresponding first PO / first PF is Δt, the first LO overlaps the transmission time of the LP-SS, and the first device can delay the first LO to a time domain position that is different from the overlapping LP-SS by X time domain resources, that is, the start time (time domain start position) of the delayed first LO and the end time (time domain end position) of the transmission time of the overlapping LP-SS are different by X symbols. The value of X can be designed according to the time for the terminal device to process the LP-SS, the time for switching the sampling rate, and the like, and is not limited in this regard.

[0170] In the communication method shown in FIG. 9, the first device can determine that the first LO and the transmission time of the first signal overlap in the time domain according to the acquired first configuration information for configuring the first LO for transmitting the first LP-WUS and the second configuration information for configuring the transmission time of the first signal, and determine to invalidate the first LO, for example, determine not to transmit the LP-WUS on each LP-WUS MO in the first LO, or determine not to transmit the LP-WUS on the group of LP-WUS MOs in the first LO that overlap the transmission time of the first signal, or determine not to transmit the LP-WUS on the LP-WUS MO in the first LO that overlaps the transmission time of the first signal, or determine to delay the first LO to a time domain position that does not overlap the transmission time of the first signal to transmit the LP-WUS, which can solve the problem of the conflict between the transmission of the LP-WUS and the first signal.

[0171] In addition, the embodiment of the present application further provides a communication method. A first device can select a valid LP-WUS MO from a plurality of configured LP-WUS MOs, which can be used to transmit a LP-WUS. The valid LP-WUS MO constitutes a first LO, or in other words, the LP-WUS MOs contained in the first LO are all valid MOs capable of transmitting a LP-WUS.

[0172] For example, FIG. 14 is a flowchart of another communication method provided by the embodiment of the present application. As shown in FIG. 14, the communication method comprises the following steps.

[0173] In S1401, a first device acquires first configuration information.

[0174] The first device can be a first terminal device or a chip of the first terminal device, or a network device or a chip of the network device. The first LP-WUS is a signal used to wake up an MR of the first terminal device. The descriptions of the first device and the first LP-WUS can be referred to the descriptions in the method embodiment shown in FIG. 9.

[0175] The first configuration information is used to configure a plurality of LP-WUS MOs for transmitting the first LP-WUS. The plurality of LP-WUS MOs configured by the first configuration information can be periodic or aperiodic time domain resources defined in the time domain in advance. One LP-WUS MO can occupy L time domain resources (L is a positive integer). For example, the time domain resource usually refers to a slot or a symbol. One LP-WUS MO can occupy one slot (one slot can be configured as one LP-WUS MO), or occupy a plurality of symbols in one slot (for example, every T symbols are configured as one LP-WUS MO). One slot can be configured with one or more LP-WUS MOs.

[0176] The plurality of LP-WUS MOs configured by the first configuration information can be regularly arranged in the time domain, such as periodically arranged, or arranged every interval of symbols, or irregularly arranged, which is not limited.

[0177] For example, as shown in FIG. 15, one LP-WUS MO occupies 4 symbols, each time slot includes 14 symbols, and the indexes are 0-13. In each time slot, the symbols with indexes 2-5 are configured as one LP-WUS MO, and the symbols with indexes 10-13 are configured as one LP-WUS MO. Thus, the first configuration information can include the starting time domain position of the first LP-WUS MO in the plurality of LP-WUS MOs and / or the number of LP-WUS MOs. For example, the first configuration information configures S LP-WUS MOs, S is a positive integer, or configures the period of the LP-WUS MOs, the number of occurrences of the LP-WUS MOs in each period, and the time domain position. This is not limited.

[0178] The plurality of LP-WUS MOs configured by the first configuration information can be considered as a set of LP-WUS MOs configured to transmit the first LP-WUS. The LP-WUS MOs in the set are configured to transmit the LP-WUS.

[0179] It should be understood that the plurality of LP-WUS MOs configured by the first configuration information can be located in the T p1 P=MxNxK, T p1 The starting time of the first PF or the first PO for the first terminal device to detect the paging is Δt, and Δt is a time offset value. The description of the first PF and the first PO can refer to the description in S901 above, which is not repeated here.

[0180] If the first device is the first terminal device or a chip of the first terminal device, the first device obtaining the first configuration information can include that the first terminal device receives the first configuration information from the network device. Correspondingly, if the first device is the network device or a chip of the network device, the first device obtaining the first configuration information can include that the network device locally configures the first configuration information and sends the first configuration information to the first terminal device.

[0181] S1402, the first device selects P LP-WUS MOs from the plurality of LP-WUS MOs according to the first configuration information, which do not overlap with the transmission time of the first signal.

[0182] Wherein, P is a positive integer, the P LP-WUS MOs can be used for the first LP-WUS transmission, it can be understood that the P LP-WUS MOs are MOs in the plurality of LP-WUS MOs configured by the first configuration information and can effectively transmit the first LP-WUS, or the P LP-WUS MOs will transmit the LP-WUS, the first LP-WUS will be transmitted on part of the P LP-WUS MOs, and whether the received LP-WUS on the P LP-WUS MOs is the first LP-WUS is determined by the first terminal device according to the parsed wake-up information.

[0183] After the first device obtains the first configuration information, the time domain positions of the plurality of LP-WUS MOs can be known according to the first configuration information, and P LP-WUS MOs that do not overlap with the transmission time of the first signal can be selected from the plurality of LP-WUS MOs according to the transmission time of the configured first signal. The configuration information for indicating the transmission time of the first signal and the specific description of the first signal can be referred to the related description of the second configuration information in S901 described above, and will not be described here.

[0184] The P LP-WUS MOs selected by the first device can constitute a first LO, which corresponds to the first PF or the first PO for detecting the paging of the first terminal device, and also satisfies the following characteristics:

[0185] The P LP-WUS MOs are located in the first LO at T p1 -t time, wherein P=M*N*K, T p1 is the starting time of the first PF or the first PO for detecting the paging of the first terminal device, Δt is a time offset value, M is the number of LP-WUS MO groups in the first LO, N is the number of beam transmission directions of each LP-WUS MO group, K is the number of LP-WUS MOs corresponding to the same beam transmission direction in each LP-WUS MO group, and M, N and K are positive integers.

[0186] It can be considered that the P LP-WUS MOs are all valid MOs, the first LO is defined as containing the P valid MOs located after T p1 -t time, and the P LP-WUS MOs can be divided into M LP-WUS MO groups, and each LP-WUS MO group contains N*K LP-WUS MOs.

[0187] The P LP-WUS MOs are each separated from the transmission time of the first signal by Y time domain resources, Y being a positive integer, in consideration of the processing time of the signal. The Y time domain resources can include time domain resources that are separated before and after the transmission time of the first signal.

[0188] If the first device is a first terminal device or a chip of the first terminal device, the first terminal device receives the first LP-WUS on the first LO. Correspondingly, if the first device is a network device or a chip of the network device, the network device transmits the first LP-WUS on the first LO.

[0189] It should be understood that each LP-WUS MO group in one LO is used to transmit one LP-WUS, and the first LP-WUS can be transmitted on any LP-WUS MO group in the first LO, and different LP-WUS MO groups are used to transmit different LP-WUS. The first terminal device receives and detects the LP-WUS transmitted by each LP-WUS MO group in the first LO, and determines whether the wake-up information carried by the LP-WUS can wake up the terminal device. If yes, it is the first LP-WUS, otherwise, it is not the first LP-WUS.

[0190] Based on the above-mentioned manner of defining the LO, in a possible scenario, when two consecutive PFs / POs corresponding to the LO transmitted periodically by the network device overlap in time, taking the above-mentioned first LO and second LO as an example: the first LO used to transmit the first LP-WUS corresponds to the first PF or the first PO in which the first terminal device detects paging, and the first PO is a PO in the first PF; the second LO used to transmit the second LP-WUS corresponds to the second PF or the second PO in which the second terminal device detects paging, and the second PO is in the second PF, the second LP-WUS is used to wake up the MR of the second terminal device, and the second LO includes P LP-WUS MOs. The P LP-WUS MOs in the second LO are all non-overlapping with the transmission time of the first signal. The specific description of the first LO and the second LO can be referred to the related description of the first LO in S901 above, which will not be repeated here.

[0191] It should be understood that the second PF or the second PO can be located before or after the first PF or the first PO, and no limitation is made thereto.

[0192] At this time, the first LO and the second LO are both P LP-WUS MOs selected by the first device from the configured multiple LP-WUS MOs and not overlapping with the transmission time of the first signal. It should be understood that the number of LP-WUS MOs contained in the LO in which each terminal device receives the LP-WUS is usually the same, and the determination manner of the LO corresponding to each terminal device is as described above for the determination manner of the first LO.

[0193] The first device can obtain position information of the second LO used for transmitting the second LP-WUS, and determine, according to the first configuration information and the position information of the second LO, that part of the LP-WUS MOs in the first LO overlap part of the LP-WUS MOs in the second LO in the time domain. Illustratively, the first configuration information includes the position information of the second LO used for transmitting the second LP-WUS, or the first device can determine the position information of the second LO used for transmitting the second LP-WUS according to the first configuration information and the transmission configuration of the PF / PO.

[0194] In the case that part of the LP-WUS MOs in the first LO overlap part of the LP-WUS MOs in the second LO in the time domain, there are two design schemes as follows:

[0195] Design scheme 1: The first device determines not to transmit the first LP-WUS on the overlapping LP-WUS MOs.

[0196] If the first device is a first terminal device or a chip of the first terminal device, the first terminal device does not receive the first LP-WUS on the LP-WUS MOs in the first LO that overlap part of the LP-WUS MOs in the second LO. Correspondingly, if the first device is a network device or a chip of the network device, the network device does not transmit the first LP-WUS on the overlapping LP-WUS MOs, but transmits the second LP-WUS. It can be understood that the LP-WUS MOs used for transmitting the first LP-WUS contained in the first LO are reduced, and the LP-WUS MOs used for transmitting the second LP-WUS contained in the second LO remain unchanged.

[0197] In the design scheme 1, the first device directly invalidates the LP-WUS MOs in the first LO that overlap.

[0198] Design scheme 2: The first device determines that the first LP-WUS is allowed to be transmitted on the overlapping LP-WUS MOs.

[0199] If the first device is a first terminal device or a chip of the first terminal device, the first terminal device can receive the first LP-WUS on the LP-WUS MOs in the first LO that overlap part of the LP-WUS MOs in the second LO. Whether the first terminal device can receive the LP-WUS on the overlapping LP-WUS MOs is determined by the network device, that is, if the first device is a network device or a chip of the network device, the network device can select to transmit the LP-WUS corresponding to the first LO or the LP-WUS corresponding to the second LO on the overlapping LP-WUS MOs.

[0200] In the design scheme 2, whether the overlapping LP-WUS MO in the first LO is processed as invalid depends on the selection of the network device side.

[0201] For example, as shown in FIG. 16, PF1 / PO1 corresponds to LO1, LO1 is discontinuous and consists of two parts, PF2 / PO2 is a PF / PO after PF1 / PO1, PF2 / PO2 corresponds to LO2, LO1 and LO2 overlap in part of the LP-WUS MO in the time domain, the network device can not send the LP-WUS corresponding to LO1 on the overlapping LP-WUS MO in LO1, and send the LP-WUS corresponding to LO2 on the entire LO2, or the network device can send the LP-WUS corresponding to LO1 on the entire LO1, and not send the LP-WUS corresponding to LO2 on the overlapping LP-WUS MO in LO2.

[0202] In the communication method shown in FIG. 14, the first device can select P LP-WUS MOs that do not overlap with the transmission time of the first signal from the plurality of LP-WUS MOs configured according to the obtained first configuration information, thereby forming a first LO for transmitting LP-WUS, which can solve the problem of LP-WUS and first signal transmission conflict.
