[0001] This application claims priority to the Chinese Patent Application No. 202411259088.9, filed on September 9, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

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

[0003] In the fifth generation (5 th generation,5G) new radio (NR) system, a terminal device needs to wake up in advance for a long time to receive multiple synchronization signals and / or reference signals, so that the terminal device is woken up for a long time, and the power consumption is high. Therefore, how to reduce the power consumption of the terminal device is a problem to be solved in the field. SUMMARY

[0004] The present application provides a communication method and a communication apparatus, which can reduce the power consumption of the terminal device.

[0005] In a first aspect, a communication method is provided. The method can be applied to the terminal side, that is, the method can be executed by a terminal device, or can be executed by a component (such as a chip or a chip system or a circuit or a communication module) of the terminal device, which is not limited in the present application. Hereinafter, the terminal device will be mainly taken as an example for description.

[0006] The method can include: receiving at least one first signal in a first signal set, the first signal set being periodically transmitted, the first signal set including a plurality of first signals in a first transmission period of the first signal set, the first signal corresponding to a first beam direction, and the first signal set including at least a signal for synchronization; and processing the at least one first signal.

[0007] Based on the above technical solution, the first signal set transmitted by the network device in the first transmission period can include a plurality of first signals for synchronization, and the plurality of first signals correspond to the same beam direction, thereby improving the density of the local first signal. The terminal device can receive at least one first signal in the plurality of first signals in a shorter time for subsequent processing, thereby reducing the power consumption of the terminal device.

[0008] For example, the terminal device can receive multiple reference signals in a shorter time, thereby completing time-frequency synchronization and / or measurement more quickly, reducing the time window length required by the terminal device to receive the multiple reference signals, and reducing the power consumption of the terminal device.

[0009] With reference to the first aspect, in some implementations of the first aspect, in the first sending period, the first signal set further includes multiple second signals corresponding to a second beam direction, the second beam direction being different from the first beam direction.

[0010] Based on the above technical solution, the first signal set sent by the network device can include multiple signals corresponding to multiple different beam directions, so that the terminal device can select to receive a signal (for example, a signal corresponding to a beam direction with better quality) with better quality (for example, a signal corresponding to a beam direction with better quality) and perform subsequent processing on the signal with better quality, thereby improving the accuracy of subsequent processing.

[0011] With reference to the first aspect, in some implementations of the first aspect, in the first sending period, the multiple first signals included in the first signal set are adjacent in time domain.

[0012] Based on the above technical solution, the first signal set sent by the network device includes multiple first signals adjacent in time domain, so that the terminal device can further reduce the time required to receive multiple first signals, thereby reducing the power consumption of the terminal device.

[0013] With reference to the first aspect, in some implementations of the first aspect, at least one second signal is included between the time domain positions of any two first signals.

[0014] With reference to the first aspect, in some implementations of the first aspect, in a second sending period of the first signal set, the first signal set includes one first signal, and the second sending period is different from the first sending period.

[0015] Based on the above technical solution, the first signal set sent by the network device in the second sending period can include one first signal, wherein the second sending period is different from the first sending period, so that the first signals can be sent more densely in some time positions (for example, in the first sending period) and more sparsely in some time positions (for example, in the second sending period). The dense and sparse first signals are used in combination, so that the terminal device can search for a network through one or more first signals in the first period and search for a network through one first signal in the second period, thereby shortening the network search time of the terminal device, while keeping the signal overhead small.

[0016] With reference to the first aspect, in some implementations of the first aspect, the method further includes receiving the paging at a paging occasion, the paging occasion being determined according to the time domain position of the first signal set.

[0017] With reference to the first aspect, in some implementations of the first aspect, the paging occasion is determined according to the time domain position of the first signal set, including that the time domain position of the paging occasion is after the time domain position of the first signal set, and the time domain position of the paging occasion is spaced apart from the last signal in time domain of the first signal set by P time units, P being an integer greater than or equal to 0.

[0018] Based on the above technical solutions, the paging occasion at which the terminal device receives the paging is determined according to the time domain position of the first signal set, and specifically, the paging occasion can be within a time domain range less than the first threshold after the first signal set, thereby further shortening the time window length required by the terminal device to receive the first signal and the paging, and further reducing the power consumption of the terminal device.

[0019] With reference to the first aspect, in some implementations of the first aspect, the method further includes receiving the paging at a paging occasion, the paging occasion being determined according to the time domain position of the first signal set.

[0020] With reference to the first aspect, in some implementations of the first aspect, the paging occasion is determined according to the time domain position of the first signal set, including that the time domain position of the paging occasion is after the time domain position of the first signal set, and the time domain position of the paging occasion is spaced apart from the last signal in time domain of the first signal set by P time units, P being an integer greater than or equal to 0.

[0021] Based on the above technical solutions, the paging occasion at which the terminal device receives the paging is determined according to the time domain position of the first signal set, and specifically, the paging occasion can be within a time domain range less than the first threshold after the first signal set, thereby further shortening the time window length required by the terminal device to receive the first signal and the paging, and further reducing the power consumption of the terminal device.

[0022] With reference to the first aspect, in some implementations of the first aspect, the paging occasion is determined according to the time domain position of the first signal set, including that the paging occasion is determined according to the time domain position of the first signal set within the first transmission period.

[0023] Based on the technical solution, the paging occasion is determined according to the time domain positions of the first signal set in the first sending period, the first signal set in the first sending period includes multiple first signals, and the terminal device quickly completes synchronization and other operations based on the multiple first signals, thereby preparing to receive the paging, thereby further shortening the time window length required by the terminal device to receive the multiple first signals and the paging, and further reducing the power consumption of the terminal device.

[0024] In combination with the first aspect, in some implementations of the first aspect, the paging occasion is determined according to the time domain positions of the multiple first signals included in the first signal set, including that the paging occasion is determined according to the time domain positions of the multiple first signals included in the first signal set in the first sending period.

[0027] Based on the technical solution, the network device sends multiple third signals in different periods, the multiple third signals correspond to the same beam direction, so that the terminal device can receive at least one third signal in the multiple third signals in a shorter time for subsequent processing, thereby reducing the power consumption of the terminal device.

[0028] For example, the terminal device can receive multiple reference signals in a shorter time, thereby more quickly completing time-frequency synchronization and / or measurement, reducing the time window length required by the terminal device to receive the multiple reference signals, and reducing the power consumption of the terminal device.

When it is understood that the indication information carries A, "indication" can be replaced by "includes", at this time, similar to the expression "sending / receiving indication information, the indication information indicates A", it can be replaced by "sending / receiving A".

[0089] In this application, the information indicated by the indication information is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information has an association relationship with the to-be-indicated information. The to-be-indicated information can also be indicated only by a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, the protocol stipulates), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0090] (2) In this application, the expression " / " is used to represent that the objects before and after the association are in an "or" relationship; for example, A / B can represent A or B. The expression "and / or" is used to represent that the objects before and after the association can be in an "and" association relationship or an "or" association relationship; for example, A and / or B can represent the following cases: A exists alone, B exists alone, A and B exist together, where A and B can be single or multiple. "At least one of the following" or similar expressions are used to represent any combination of the listed items; for example, at least one of A, B and (or) C can represent the following cases: A exists alone, B exists alone, C exists alone, A and B exist together, B and C exist together, A and C exist together, A, B and C exist together, where A, B and C can be single or multiple.

[0091] (3) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

They are not used to describe the order or sequence of features. It should be understood that such described objects can be interchanged where appropriate so as to describe solutions other than those in the embodiments of this application.

[0095] (7) In this application, "predefined" can mean a standard protocol predefined, or it can mean a pre-agreed or pre-negotiated agreement between devices. Here, "protocol" can refer to a standard protocol in the field of communications, such as a fourth-generation (4G) protocol. th Generation 4G network, fifth generation (5G) network th This application does not limit the scope to network protocols such as generation (5G), new radio (NR) protocols, 5.5G network protocols, future communication network protocols, and related protocols applied in future communication systems.

[0096] (8) In this application, the words "example," "such as," and "for example" are used to mean that an implementation so described is one among many possible implementations. No inference should be drawn that any other implementation is "preferred" or "constitutes all other implementations." The word "example" is used herein to mean one of a number of possible implementations, and not necessarily the preferred or advantageous implementation.

[0112] In combination with FIG. 1, a communication system suitable for the embodiment of the present application is briefly introduced as follows.

[0113] Referring to FIG. 1, as an example, FIG. 1 is a schematic diagram of a wireless communication system suitable for the embodiment of the present application. As shown in FIG. 1, the wireless communication system includes a radio access network 100. The radio access network 100 can be a next-generation (for example, a future communication network or a higher version) radio access network, or a traditional (for example, 5G, 4G, 3G or 2G) radio access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be connected to each other or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100. The network elements in the wireless communication system are connected through an interface (for example, NG, Xn), or connected through an air interface.

[0114] In the communication between the network device and the terminal device, the network device can manage one or more cells, and each cell can include at least one terminal device. The cell can be understood as an area within the coverage range of the wireless signal of the network device.

[0115] FIG. 1 is only a schematic diagram, and the wireless communication system can also include other devices, such as a core network device, a wireless relay device and / or a wireless backhaul device, etc., which are not shown in FIG. 1.

[0116] In order to facilitate the understanding of the embodiments of the present application, the terms involved in the present application are briefly explained.

[0117] 1. Paging reception in 5G NR:

[0118] When a terminal device is in an idle state or an inactive state, the terminal device periodically receives paging. Specifically, the terminal device calculates a paging frame (PF) and a location of a paging occasion (PO) in the PF according to an identity document (ID) of the terminal device, and monitors a paging physical downlink control channel (PDCCH) in the PO. If the terminal device monitors the paging PDCCH, the terminal device receives a paging physical downlink shared channel (PDSCH) at a location scheduled by the paging PDCCH. The paging PDSCH includes a paging message, and the paging message specifically indicates which terminal devices are paged.

[0119] The system frame number (SFN) in which the PF is located is determined according to the following formula:

[0120] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0121] The PO sequence number i_s that the terminal device needs to monitor in the PF is:

[0122] i_s=floor(UE_ID / N)mod Ns

[0123] wherein, PF_offset is an offset value used to determine the PF, T is a discontinuous reception (DRX) cycle in the IDLE state, N is the number of PFs in the time T, UE_ID is the ID of the terminal device, and Ns is the number of POs in one PF.

[0124] The above formula for determining the PO location can be understood as follows:

[0125] (1) (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N), that is, all terminal devices are divided into N groups according to UE_ID, and the UE is determined to be in which group according to the value of UE_ID mod N, which corresponds to which PF.

[0126] Referring to FIG. 2, FIG. 2 is a schematic diagram of a paging frame and a paging occasion applicable to an embodiment of the present application.

[0127] For example, as shown in FIG. 2, in FIG. 2, N = 4, if the UE_ID of the terminal device is a string of binary numbers, the final group or the final PF in which the terminal device is located can be determined by the last two bits of the UE_ID.

[0128] (2) i_s = floor(UE_ID / N) mod Ns, wherein UE_ID / N is equivalent to taking out a certain group in the first step, that is, focusing on a certain PF. And further mod Ns is equivalent to dividing the terminal device into Ns groups in one step, and according to the value of mode Ns, it is determined which group or which PO.

[0129] (3) In general, there are N*Ns POs in a DRX cycle, and the terminal device is also divided into N*Ns groups according to the UE_ID, each group corresponding to a PO.

[0130] For example, please continue to refer to FIG. 2, in FIG. 2, N = 4, that is, there are 4 PFs in a DRX cycle T; Ns = 5, that is, there are 5 POs from paging occasion 0 to paging occasion 4 in a PF.

[0131] Further, a PO can also contain multiple monitoring occasions (MOs), and different MOs correspond to different beam directions. Therefore, the length of a PO can be several slots.

[0132] 2. Synchronization signal and physical broadcast channel block (SSB) transmission in 5G NR:

[0133] In the 5G NR system, the synchronization signal is transmitted in the SSB. According to the 5G NR standard, the position of the SSB in each half frame (5ms) is predefined in the protocol according to the frequency range in which the cell is located and the subcarrier spacing. Multiple SSBs in each half frame form a synchronization signal burst set (SS burst set), and each SSB in an SS burst set usually corresponds to a different beam direction. Therefore, for a certain terminal device, only one SSB in an SS burst set is usually used for time-frequency synchronization, and multiple SSBs due to different beam directions may even lead to a decrease in synchronization accuracy.

[0134] As an example, the periodicity of the SS burst set is configurable, but typically takes a default value of 20 ms. For example, when searching for a network, the terminal device can assume that the periodicity of the SS burst set is 20 ms.

[0135] It can be seen that the position of the PO and the position of the SSB can be independently configured or defined, and the relative distance between the two can be long or short.

[0136] 3. Technical problems of 5G compared to 4G

[0137] Before the terminal device receives the paging in the PO, it needs to perform time-frequency synchronization based on the synchronization signal and / or reference signal. Since the terminal device can receive the paging PDCCH and the paging PDSCH in the PO, the terminal device can need multiple synchronization signals and / or reference signals to complete more accurate time-frequency synchronization. For example, the terminal device can use one synchronization signal or reference signal to complete coarse time and / or frequency synchronization, but need two or three or even more synchronization signals and / or reference signals to complete fine time and / or frequency synchronization.

[0138] In the 4G LTE system, there is a cell-specific reference signal (CRS) in each subframe. Therefore, the terminal device can wake up in a short time before its own corresponding PO, that is, the terminal device can be converted from a non-working / non-receiving / sleeping state to a working / receiving / non-sleeping state, and complete fine time-frequency synchronization according to the CRS. In the 5G NR system, since the periodicity of the SS burst set or SSB is large, the terminal device needs to wake up in a long time before its own corresponding PO. In this way, in the 5G NR system, compared to in the 4G LTE system, the terminal device wakes up for a longer time, and the power consumption is correspondingly higher.

[0139] In view of this, the present application proposes that by designing a first signal set including a plurality of first signals corresponding to the same beam direction and at least used for synchronization, the power consumption of the terminal device can be reduced.

[0140] The method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to the scenarios shown in the above figures, without limitation.

[0141] Referring to FIG. 3, as an example, FIG. 3 is a schematic diagram of a communication method 300 provided by the embodiments of the present application. For ease of description, the terminal device and the network device are taken as examples for exemplary description. The terminal device can be replaced by a component (for example, a chip or a chip system or a circuit or a communication module) of the terminal device, and the network device can be replaced by a component (for example, a chip or a chip system or a circuit or a communication module) of the network device. In addition, the steps described below can be executed by a single execution subject, and can also be divided into multiple execution subjects which can be logically and / or physically separated. The method 300 shown in FIG. 3 can include the following steps.

[0142] 310. The network device transmits a first signal set, and the terminal device receives at least one first signal in the first signal set accordingly.

[0143] The signals included in the first signal set are at least used for synchronization.

[0144] For example, the terminal device can receive at least one signal in the first signal set, and complete synchronization of time and / or frequency with the network device according to the at least one signal.

[0145] For example, the signals included in the first signal set can also be understood as signals transmitted by the network device in the time domain range of the first signal set.

[0146] For example, the first signal set can include one or more signals at least used for synchronization, and the first signal belongs to the one or more signals at least used for synchronization.

[0147] It should be noted that any one of the signals at least used for synchronization in the first signal set can also be referred to as a signal resource or a signal instance, and the naming does not limit the protection scope of the embodiments of the present application.

[0148] Referring to FIG. 4, FIG. 4 is a schematic diagram of a first signal set provided by the embodiments of the present application.

[0149] For example, as shown in FIG. 4, each block can represent a signal at least used for synchronization (or a signal resource or a signal instance), and the position of the block on the horizontal axis can represent the time domain position of the transmitted signal. The first signal set can include 8 signals adjacent in the time domain.

[0150] Optionally, the first signal set can include one or more signal blocks, for example, the first signal set can include one or more SSBs.

[0151] Optionally, the first signal set can include one or more reference signals.

[0152] As an example, the signals included in the first signal set can also be used for measurement.

[0153] As an example, the first signal set is periodically transmitted. Alternatively, the first signal set periodically occurs.

[0154] It should be noted that in the embodiments of the present application, the periodicity can be understood as the time interval between two periodic transmissions.

[0155] Optionally, the periodicity of the first signal set is configured or predefined.

[0156] As an example, the first signal set can include a plurality of first signals used at least for synchronization in a first transmission period of the first signal set.

[0157] It should be noted that in the embodiments of the present application, the transmission period can be replaced by a transmission time period or a transmission time interval, etc., which can be understood as a specific time period or a position of the occurrence of the signal used at least for synchronization in a specific time period, for example, a position of the occurrence of the reference signal or the synchronization signal in a specific time period.

[0158] The first transmission period can be understood as one or more time domain positions in which the network device completely transmits a first signal set. Alternatively, the first transmission period can be part or all of the transmission period of the first signal set.

[0159] For example, the first transmission period can correspond to the time period occupied by the period #1 mark in FIG. 4, or the first transmission period can correspond to the time period corresponding to the 8 blocks in the time period occupied by the period #1 mark in FIG. 4, and the first signal set in the first transmission period can be a signal set composed of the 8 signals in the time domain at the front in FIG. 4.

[0160] In addition, the first signal can correspond to the first beam direction. That is, when there are a plurality of first signals, the beam directions of the plurality of first signals are the same.

[0161] For example, please continue to refer to FIG. 4, the different patterns in the box in FIG. 4 can represent different beam directions, for example, the 2 blocks with vertical lines in the pattern under period #1 in FIG. 4 can represent 2 first signals in the first transmission period.

[0162] As a possible implementation manner, the first signal set further includes a plurality of second signals corresponding to a second beam direction, and the second beam direction is different from the first beam direction.

[0163] For example, please continue to refer to FIG. 4, the square with horizontal lines in FIG. 4 can represent the second signal, and the beam direction of the second signal is different from the beam direction of the first signal.

[0164] In the embodiment of the present application, the first signal set sent by the network device can include multiple signals corresponding to multiple different beam directions, so that the terminal device can select to receive a signal with better quality (for example, a signal corresponding to a beam direction with better quality), for example, a first signal, and perform subsequent processing on the signal with better quality, thereby improving the accuracy during subsequent processing.

[0165] Optionally, in the first sending period of the first signal set, for any beam direction existing in the first signal set, the first signal set includes multiple signals corresponding to the beam direction.

[0166] For example, for any signal (denoted as signal #1) in the first signal set, the corresponding beam direction is denoted as beam direction #1, and there is at least another signal #2 in the first signal set, and the corresponding beam direction of signal #2 is also beam direction #1.

[0167] For example, please continue to refer to FIG. 4, which includes four patterns corresponding to four beam directions. By designing the mode of the reference signal sent by the network device, the density of the reference signal corresponding to each beam direction is locally increased.

[0168] In the embodiment of the present application, the first signal set sent by the network device in the first sending period can include multiple first signals at least for synchronization, and the multiple first signals correspond to the same beam direction, so that the terminal device can receive at least one first signal in the multiple first signals in a shorter time for subsequent processing, thereby reducing the power consumption of the terminal device.

[0169] For example, the terminal device can receive multiple reference signals in a shorter time, thereby more quickly completing time-frequency synchronization and / or measurement, reducing the time window length required by the terminal device to receive the multiple reference signals, and reducing the power consumption of the terminal device.

[0170] In the following, the arrangement mode of the signals in the first signal set is illustrated by way of example 1 and example 2.

[0171] Example 1, the signals corresponding to different beam directions in the first signal set appear alternately.

[0172] Specifically, the network device can first traverse each beam direction to send one signal, and then traverse each beam direction to send one signal each time the first signal set is sent, and multiple signals are sent for the same beam direction through multiple traversals.

[0173] As an example, at least one second signal is included between any two time-domain locations of the first signals.

[0174] For example, referring to Figure 4, within the first transmission period corresponding to period #1, the square with the vertical line pattern is considered the first signal, and the other squares with any pattern are considered the second signal. It can be seen that between the two squares with the vertical line pattern, the squares with other patterns appear once each, meaning that at least one second signal is included between the time-domain positions of the two first signals.

[0175] Method 2: Signals in the first signal set that correspond to the same beam direction are adjacent in the time domain.

[0176] As an example, in the first transmission period, the first signal set includes multiple first signals that are temporally adjacent.

[0177] Referring to Figure 5, Figure 5 is a schematic diagram of another first signal set provided in an embodiment of this application.

[0178] It should be noted that the main difference between Figure 5 and Figure 4 is the arrangement of the patterns within the boxes. For the meaning of the graphics in Figure 5, please refer to the description in Figure 4. The embodiments of this application will not be repeated here.

[0179] For example, as shown in Figure 5, in the first transmission period corresponding to period #1, the square with the pattern of vertical lines is still regarded as the first signal. It can be seen that the two squares with the pattern of vertical lines are adjacent, that is, the two first signals are adjacent in the time domain.

[0180] As an example, in Method 2, when the network device sends the first set of signals each time, it can continuously send multiple signals in each beam direction, and then switch the beam direction to continue sending signals, so that signals in the same beam direction are adjacent in the time domain.

[0181] For example, in Figure 5, within one transmission cycle, blocks with the same pattern are adjacent to each other, that is, signals in the first signal set corresponding to the same beam direction are temporally adjacent.

[0182] In this embodiment of the application, the first signal set sent by the network device includes multiple first signals that are adjacent in the time domain, thereby the terminal device can further reduce the time required to receive multiple first signals and reduce the power consumption of the terminal device.

[0183] Referring to Figure 6, which is a schematic diagram of another first signal set provided in an embodiment of this application.

[0184] The following, with reference to Figure 6, illustrates two ways of defining the period of the first signal set using Definition 1 and Definition 2.

[0185] Definition 1: The period of the first signal set is period #2 as shown in Figure 6.

[0186] As an example, the number of signals corresponding to the same beam direction in the first signal set can be different in different transmission periods. For example, the number of signals corresponding to the same beam direction in the first signal set is greater than 1 in transmission period #A, and the number of signals corresponding to the same beam direction in the first signal set is equal to 1 in transmission period #B.

[0187] Optionally, the number of signals corresponding to the same beam direction in the first signal set is greater than 1 before the PF or PO front position, and otherwise the number of signals corresponding to the same beam direction is equal to 1.

[0188] As an example, the first signal set includes one first signal in the second transmission period of the first signal set.

[0189] Wherein, the second transmission period is different from the first transmission period.

[0190] For example, as shown in FIG. 6, the network device transmits the first signal set in period #2, and in the first transmission period of the first signal set, the first signal set includes a plurality of first signals, which are represented by two adjacent blocks in FIG. 6; in the second transmission period of the first signal set, the first signal set includes one first signal, which is represented by a single block in FIG. 6.

[0191] Optionally, period #2 can be equal to 20ms.

[0192] Definition 2, the period of the first signal set is period #3 shown in FIG. 6.

[0193] As an example, in one transmission period, the signals in the first signal set can appear continuously multiple times first, and then appear once after a period of time.

[0194] It should be noted that the continuous appearance of the signal is not limited to complete continuity in time, and the continuous appearance of the signal can be related to the traversal manner of the signals corresponding to different beam directions. For example, in the two signal arrangement manners described in the foregoing manner 1 and manner 2, the first signal can be understood as continuously appearing. The embodiments of the present application do not limit the manner of continuous appearance of the signal.

[0195] As an example, as shown in FIG. 6, in the third transmission period of the first signal set, the last first signal in the first signal set appears on time unit #1, and time unit #2 is the previous time unit of time unit #1. Wherein, no signal in the first signal set appears on time unit #2.

[0196] As an example, a time unit can include one or more time slots, subframes, or symbols, etc.

[0197] As an example, the third transmission period can be the first transmission period described above plus the second transmission period.

[0198] For example, as shown in FIG. 6, the network device transmits the first signal set in a period #3, in the third transmission period of the first signal set, a plurality of first signals appear in time domain in succession, the plurality of first signals are represented by two adjacent blocks in FIG. 6, and one first signal appears at a time interval position, the one first signal is represented by a single block in FIG. 6.

[0199] Optionally, the period #3 can be equal to 40 ms.

[0200] It should be understood that the first signal set shown in FIG. 6 is only used to illustrate the embodiments of the present application, and does not limit the protection scope of the embodiments of the present application. The embodiments of the present application do not limit the specific number or specific arrangement order of the signals in the first signal set and other attributes.

[0201] In the embodiments of the present application, the first signal set transmitted by the network device in the second transmission period can include one first signal, wherein the second transmission period is different from the first transmission period, so that the first signals can be transmitted more densely at some time positions (for example, in the first transmission period) and more sparsely at some time positions (for example, in the second transmission period). The dense and sparse first signals are used in combination, so that the terminal device can search for a network through one or more first signals in the first period and search for a network through one first signal in the second period, thereby shortening the network search time of the terminal device, while keeping the signal overhead small.

[0202] 320, the terminal device processes the at least one first signal.

[0203] As an example, the terminal device processing the at least one first signal can include the terminal device performing time-frequency synchronization and / or radio resource management (RRM) measurement according to the at least one first signal.

[0204] As a possible implementation manner, the terminal device receives the paging information at a paging occasion #1, and the paging occasion #1 is determined by the terminal device after time-frequency synchronization according to the at least one first signal.

[0205] Optionally, the position of the paging occasion is configured. For example, the position of the paging occasion is configured in the vicinity of the first signal set.

[0206] Referring to FIG. 7, FIG. 7 is a schematic diagram of a paging occasion position according to an embodiment of the present application.

[0207] For example, the period of the first signal set in FIG. 7 is period #4, and the white square boxes arranged adjacently can represent the first signal set, the first signal set includes multiple signals corresponding to one beam direction, and the time domain position of the paging occasion is configured to be after the time domain position of the first signal set. Alternatively, the white square boxes arranged adjacently can represent multiple first signals, and the time domain position of the paging occasion is configured to be after the time domain position of the multiple first signals.

[0208] In the following, two possible determination manners of the paging occasion are illustrated by way of Example 1 and Example 2.

[0209] In Example 1, the terminal device receives a paging at a paging occasion, and the paging occasion is determined according to the time domain position of the first signal set. Correspondingly, the network device sends the paging at the paging occasion.

[0210] As an example, the paging occasion can be a time unit for receiving the paging. For example, the paging occasion can include a PF or a PO.

[0211] As an example, the time domain position of the first signal set can also be understood as the time domain position at which the network device sends the signals in the first signal set.

[0212] As a possible implementation manner, the paging occasion is determined according to the time domain position of the first signal set, including that the time domain position of the paging occasion is after the time domain position of the first signal set, and the time domain position of the paging occasion is spaced apart from the last signal in the first signal set by P time units, where P is an integer greater than or equal to 0.

[0213] As an example, the time unit can include one or more time slots, subframes, or symbols, etc.

[0214] As an example, the paging occasion can be understood as the time position at which the terminal device receives the paging, or the paging occasion can also be understood as the time position at which the network device sends the paging.

[0215] As an example, the time domain position of the paging occasion is after the time domain position of the first signal set, which can also be understood as that the network device sends the paging after sending the first signal set.

[0216] Referring to FIG. 8, FIG. 8 is another schematic diagram of a paging occasion position provided by an embodiment of the present application.

[0217] As an example, as shown in (a) of FIG. 8, the first signal set includes 8 signals, and the arrangement manner of the signals corresponding to 4 different beam directions in the first signal set is the manner 1 described above. The dark square blocks in (a) of FIG. 8 can represent the paging, and the paging occasion is spaced apart from the last signal in the first signal set by offset #1. For example, the size of offset #1 can be P time units.

[0218] As another example, as shown in (b) of FIG. 8, the first signal set includes 8 signals, and the arrangement of the signals corresponding to 4 different beam directions in the first signal set is the above-mentioned manner 2. The dark squares in (b) of FIG. 8 can represent the paging, and the interval between the paging occasion and the last signal in the time domain in the first signal set is offset #2. For example, the size of offset #2 can be the above-mentioned P time units.

[0219] It should be noted that in the embodiments of the present application, the offset value can be defined as from the end of the signal to the beginning of the paging occasion, or the offset value can also be defined as from the beginning of the signal to the beginning of the paging occasion, or the offset value can also be defined as from the end of the signal to the end of the paging occasion, or the offset value can also be defined as from the beginning of the signal to the end of the paging occasion, which is not limited in the embodiments of the present application.

[0220] As an example, the paging occasion can include multiple MOs corresponding to different beam directions.

[0221] Optionally, the above-mentioned offset #1 and / or offset #2 can be configured or predefined, and the offset #1 and / or offset #2 can be configured or predefined to be less than the first threshold, so as to ensure that the distance between the paging occasion and the time domain position of the first signal set is close.

[0222] In the embodiments of the present application, the paging occasion in which the terminal device receives the paging is determined according to the time domain position of the first signal set, and specifically, the paging occasion can be within a time domain range less than the first threshold after the first signal set, so as to further shorten the time window length required by the terminal device to receive the first signal and the paging, and further reduce the power consumption of the terminal device.

[0223] Example 2, the terminal device receives the paging at the paging occasion, and the paging occasion is determined according to the time domain position of the multiple first signals included in the first signal set. Correspondingly, the network device sends the paging at the paging occasion.

[0224] As a possible implementation manner, the paging occasion is determined according to the time domain position of the multiple first signals included in the first signal set, including that the time domain position of the paging occasion is after the time domain position of the multiple first signals, and the time domain position of the paging occasion is spaced apart from the last signal in the time domain in the multiple first signals by Q time units, Q being an integer greater than or equal to 0.

[0225] As an example, the time domain position of the paging occasion is after the time domain position of the multiple first signals, which can also be understood as that the network device sends the paging after sending the multiple first signals.

[0226] Referring to FIG. 9, FIG. 9 is another schematic diagram of the position of the paging occasion provided by the embodiments of the present application.

[0227] As another example, as shown in (a) of FIG. 9 or (b) of FIG. 9, 8 signals are included in the first signal set, and the arrangement of the signals corresponding to different beam directions in the first signal set is the manner 2 described above. The dark squares in FIG. 9 can represent the paging, and the interval of the paging occasion and the signal corresponding to the last signal in time domain of the different beam directions is offset #3. For example, the size of the offset #3 can be the above-mentioned Q time units.

[0228] As an example, the MO corresponding to one beam direction can be included in the paging occasion.

[0229] For example, as shown in (a) of FIG. 9 or (b) of FIG. 9, the different patterns of the squares can represent the signals corresponding to different beam directions, and for any one of the beam directions, the MO corresponding to the beam direction is included after the signal corresponding to the beam direction. For example, the two squares in parallel with diagonal lines represent 2 signals #1 corresponding to beam direction #2, and the dark square at the position of the interval of the right side of the two squares with diagonal lines and the offset #3 represents the paging occasion determined according to the time domain position of the signal #1, and the MO corresponding to the beam direction #2 can be included in the paging occasion.

[0230] Optionally, the above-mentioned offset #3 can be configured or predefined, and the offset #3 can be configured or predefined to be less than the second threshold, so as to ensure that the paging occasion is close to the time domain position of the plurality of first signals.

[0231] Based on the above technical solutions, the paging occasion of the terminal device receiving the paging is determined according to the time domain position of the plurality of first signals, and the terminal device completes the synchronization operation and the like based on the plurality of first signals, so as to be prepared to receive the paging. Further, the paging occasion can be within the time domain range less than the second threshold after the plurality of first signals, so as to further shorten the time window length required by the terminal device to receive the first signal and the paging, and further reduce the power consumption of the terminal device.

[0232] Referring to FIG. 10, FIG. 10 is another schematic diagram of the position of the paging occasion provided by the embodiments of the present application.

[0233] For example, as shown in FIG. 10, two adjacent white squares can represent a first signal set #1 including a plurality of first signals, when the period of the first signal set is period #5a, the set #1 can be a first signal set in a fourth transmission period, the fourth transmission period can correspond to a time period occupied by the period #5a label in FIG. 10, or the fourth transmission period can correspond to a time period corresponding to the white square in the time period occupied by the period #5a label in FIG. 10; or when the period of the first signal set is period #5b, the set #1 can be part of the first signal set in a fifth transmission period, the fifth transmission period can correspond to a time period occupied by the period #5b label in FIG. 10, or the fifth transmission period can correspond to a time period corresponding to the white square in the time period occupied by the period #5b label in FIG. 10. The dark squares in FIG. 10 can represent paging occasions, the time domain positions of the paging occasions are determined according to the time domain positions of the set #1. The white square appearing alone in FIG. 10 can represent a set #2 including one first signal, when the period of the first signal set is period #5a, the set #2 can be a first signal set in a sixth transmission period, the sixth transmission period can be a next transmission period of the fourth transmission period; or when the period of the first signal set is period #5b, the set #2 can be part of the first signal set in the fifth transmission period. The time domain positions of the paging occasions can not be determined based on the time domain positions of the set #2.

[0234] As a possible implementation, the paging occasion is determined according to the time domain position of the first signal set in the foregoing, including: the paging occasion is determined according to the time domain position of the first signal set in the first transmission period.

[0235] Referring to FIG. 11, FIG. 11 is another schematic diagram of a paging occasion position provided by an embodiment of the present application.

[0236] As an example, the period of the first signal set is defined by definition 1 described in the foregoing, as shown in (a) of FIG. 11, in the fourth transmission period, the first signal set includes 8 signals, and the arrangement of the signals corresponding to 4 different beam directions in the first signal set is the manner 1 described in the foregoing. In the sixth transmission period, the first signal set includes 4 signals, and there is only one signal corresponding to any beam direction. The dark square in (a) of FIG. 11 can represent paging, and the paging occasion has an offset #1 from the last signal in the time domain in the first signal set in the fourth transmission period. There is no paging occasion after the first signal set in the sixth transmission period.

[0237] As another example, the periodicity of the first signal set is defined by definition 1 as described above, as shown in (b) of FIG. 11, in the fourth transmission period, the first signal set includes 8 signals, and the arrangement of the signals corresponding to 4 different beam directions in the first signal set is in the manner 2 as described above. In the sixth transmission period, the first signal set includes 4 signals, and there is only one signal corresponding to any beam direction. The dark squares in (b) of FIG. 11 can represent a paging, and the paging occasion is offset #2 from the interval of the last signal in time domain in the first signal set in the fourth transmission period. There is no paging occasion after the first signal set in the sixth transmission period.

[0238] Based on the above technical solutions, the paging occasion is determined according to the time domain position of the first signal set in the first transmission period, the first signal set in the first transmission period includes a plurality of first signals, and the terminal device quickly completes synchronization and other operations based on the plurality of first signals, thereby being prepared to receive paging, thereby further shortening the time window length required by the terminal device to receive the plurality of first signals and paging, and further reducing the power consumption of the terminal device.

[0239] As a possible implementation manner, the paging occasion is determined according to the time domain position of the plurality of first signals included in the first signal set, including:

[0240] The paging occasion is determined according to the time domain position of the plurality of first signals included in the first signal set in the first transmission period.

[0241] Referring to FIG. 12, as an example, FIG. 12 is a schematic diagram of a communication method 1200 provided by an embodiment of the present application. The method 1200 shown in FIG. 12 can include the following steps.

[0242] 1210, the network device transmits a second signal set and a third signal set, and correspondingly, the terminal device receives at least one third signal in the second signal set and the third signal set.

[0243] Among them, the signals included in the second signal set and the third signal set are at least used for synchronization.

[0244] For example, the terminal device can receive at least one third signal in the second signal set and the third signal set, and complete synchronization of time and / or frequency with the network device according to the at least one third signal.

[0245] As an example, the signals included in the second signal set and / or the third signal set can also be understood as signals transmitted by the network device within the time domain range of the second signal set and / or the third signal set.

[0246] As an example, the second signal set and / or the third signal set can comprise one or more signals at least for synchronization, the third signals belonging to the one or more signals at least for synchronization.

[0247] It should be noted that any one signal at least for synchronization in the second signal set and / or the third signal set can also be referred to as one signal resource or one signal instance, and the naming does not limit the protection scope of the embodiments of the present application.

[0248] As an example, the second signal set is periodically transmitted, and the third signal set is periodically transmitted. In other words, the second signal set periodically appears, and the third signal set periodically appears.

[0249] The period of the second signal set is different from the period of the third signal set.

[0250] Referring to FIG. 13, FIG. 13 is a schematic diagram of a second signal set and a third signal set provided by an embodiment of the present application.

[0251] For example, as shown in FIG. 13, the block with horizontal line pattern in FIG. 13 can be a second signal set, and the period of the second signal set is period #6; the block with vertical line pattern in FIG. 13 can be a third signal set, and the period of the third signal set is period #7. The size of period #6 is different from the size of period #7, specifically, the size of period #6 is smaller than the size of period #7.

[0252] As an example, the size of period #7 is B times the size of period #6, where B is an integer greater than 1. For example, the size of period #7 is 2 times the size of period #6.

[0253] For example, period #6 can be 20 ms, and period #7 can be 40 ms.

[0254] As an example, the second signal set comprises at least one third signal, the third signal set comprises at least one third signal, and the third signal corresponds to a third beam direction. In other words, the second signal set and the third signal set comprise signals corresponding to the same beam direction.

[0255] Referring to FIG. 14, FIG. 14 is another schematic diagram of a second signal set and a third signal set provided by an embodiment of the present application.

[0256] For example, as shown in FIG. 14, the period of the second signal set is period #6, and one second signal set comprises four signals corresponding to four different beam directions respectively; the period of the third signal set is period #7, and one third signal set comprises four signals corresponding to four different beam directions respectively; the size of period #7 is 2 times the size of period #6.

[0257] Further, for example, the third signal can be a box with vertical lines in FIG. 14, and there is one third signal in both the second signal set and the third signal set. Since the size of the period #7 is twice the size of the period #6, the third signal has a period of the period #6, and appears twice in one transmission period, once in the next transmission period, and so on.

[0258] In the embodiments of the present application, the network device transmits a plurality of third signals in different periods, and the plurality of third signals correspond to the same beam direction, so that the terminal device can receive at least one third signal in the plurality of third signals in a shorter time for subsequent processing, thereby reducing the power consumption of the terminal device.

[0259] For example, the terminal device can receive a plurality of reference signals in a shorter time, thereby more quickly completing time-frequency synchronization and / or measurement, reducing the time window length required by the terminal device to receive the plurality of reference signals, and reducing the power consumption of the terminal device.

[0260] As a possible implementation manner, the second signal set further includes a fourth signal corresponding to a fourth beam direction, the fourth beam direction being different from the third beam direction, and the third signal set further includes a fifth signal corresponding to a fifth beam direction, the fifth beam direction being different from the third beam direction.

[0261] For example, please continue to refer to FIG. 14, the second signal set can further include a fourth signal different from the beam direction of the third signal, for example, the fourth signal can be any one box with a pattern other than the vertical line in the second signal set; the third signal set can further include a fifth signal different from the beam direction of the third signal, for example, the fifth signal can be any one box with a pattern other than the vertical line in the third signal set.

[0262] 1220, the terminal device processes the at least one third signal.

[0263] As an example, the terminal device processes the at least one third signal, which can include that the terminal device performs time-frequency synchronization and / or RRM measurement according to the at least one third signal.

[0264] As a possible implementation manner, the terminal device receives the paging information at the paging occasion #2, and the paging occasion #2 is determined by the terminal device after time-frequency synchronization according to the at least one third signal.

[0265] Optionally, the position of the paging occasion is configured, and the position of the paging occasion is configured to be near a time domain position where the third signals appear more densely.

[0266] As an example, the position of the paging occasion can be configured to be after a signal set with a larger period in the second signal set and the third signal set.

[0267] Referring to FIG. 15, FIG. 15 is a schematic diagram of another position of a paging occasion provided by an embodiment of the present application.

[0268] For example, the box with horizontal line pattern in FIG. 15 can represent a second signal set, and the period of the second signal set is period #6; the box with vertical line pattern in FIG. 15 can represent a third signal set, and the period of the third signal set is period #7; the second signal set and the third signal set each include one signal corresponding to one beam direction; and the dark square in FIG. 15 can represent a paging occasion, and the time domain position of the paging occasion is configured after the second signal set and the third signal set that appear adjacently.

[0269] As a possible implementation, the terminal device receives a paging at a paging occasion, and the paging occasion is determined according to the time domain position of the second signal set and / or the third signal set. Correspondingly, the network device sends the paging at the paging occasion.

[0270] As an example, the time domain position of the second signal set and / or the third signal set can also be understood as the time domain position at which the network device sends the signal in the second signal set and / or the third signal set.

[0271] As a possible implementation, the time interval between the third signal set in the third transmission period of the third signal set and the first second signal set in time domain in front is less than the time interval between the third signal set and the first second signal set in time domain behind, the paging occasion is determined according to the time domain position of the second signal set and / or the third signal set, and the paging occasion is determined according to the time domain position of the third signal set in the third transmission period.

[0272] For example, still referring to FIG. 15, the time interval between the third signal set and the first second signal set in time domain in front is less than the time interval between the third signal set and the first second signal set in time domain behind, and the paging occasion can be determined according to the time domain position of the third signal set.

[0273] As a possible implementation, the paging occasion is determined according to the time domain position of the third signal set in the third transmission period, and the time domain position of the paging occasion is behind the time domain position of the third signal set in the third transmission period, and the time domain position of the paging occasion is spaced apart from the last signal in time domain in the third signal set in the third transmission period by R time units, R being an integer greater than or equal to 0.

[0274] For example, still referring to FIG. 15, the time domain position of the paging occasion is behind the time domain position of the third signal set, and the third signal set in the third transmission period is spaced apart from the last signal in time domain in the third signal set by offset #5. For example, the size of offset #5 can be R time units.

[0275] As an example, multiple MOs corresponding to different beam directions can be included in a paging occasion.

[0276] Optionally, the above-mentioned offset #5 can be configured or predefined, and the offset #5 can be configured or predefined to be less than the third threshold, so as to ensure that the paging occasion is close to the time-domain position of the third signal set.

[0277] In the embodiment of the application, the paging occasion in which the terminal device receives the paging is determined according to the time-domain position of the third signal set which is later in time domain in the two signal sets that are close to each other, and specifically, the paging occasion can be within a time-domain range less than the third threshold after the third signal set, so as to further shorten the time window length required for the terminal device to receive the third signal, and further reduce the power consumption of the terminal device.
