[0096] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0097] Regarding time-domain energy-saving technology, in the related art, a wake-up signal (WUS, Wake Up Signal) of a base station entering the energy-saving mode (which can also be called an energy-saving base station) is defined. When the cell of the base station is idle or has a low load, the base station will enter the energy-saving mode and stop or send SSB or system information block 1 (SIB1, System Information Block 1) with a sparse transmission period. When the terminal needs to be served by a base station (specifically, a cell) in the energy-saving state, it can send WUS to make the base station in the energy-saving state return to the normal working state.

[0098] To enable a base station in an energy-saving state to return to the normal operating mode, as Figure 1 shown, the following two scenarios can be considered: In Scenario A (which can be expressed in English as Case A), there is one or more (which can be understood as at least one) cell(s) in the area that is not in the energy-saving state (which can be expressed in English as Energy Saving) (i.e., in the working state (which can be expressed in English as Normal)); In Scenario B (which can be expressed in English as Case B), all cells in the area are in the energy-saving state to save network energy consumption. For example, in scenarios such as factory campuses and scenic spots, during specific periods (such as at night), the cells of the base station are either idle or have low load, and all cells of the base station are turned off (i.e., in the energy-saving state).

[0099] In the above scenarios, there is currently no solution on how the base station provides services to terminals with communication requirements.

[0100] Based on this, in various embodiments of the present application, the terminal sends a signal or a channel, enabling the network node (such as a cell or a base station in the energy-saving state) to send an SSB, thereby being able to provide services to the terminal.

[0101] An embodiment of the present application provides a transmission method, which is applied to a terminal. The method includes:

[0102] Sending a first signal and / or a first channel, where the sent first signal and / or first channel are used to request a first network node to send an SSB.

[0103] In actual application, the terminal can be referred to as a user equipment (UE), or can also be referred to as a user, etc. The present application embodiment does not limit the name of the terminal, as long as its function is realized. Additionally, the first signal can be referred to as a wake-up signal; the first channel can be referred to as a wake-up channel. The present application embodiment does not limit the names of the first signal and the first channel, as long as their functions are realized. The first network node can be referred to as a first network device, which can include a base station or a cell, etc., such as a base station or a cell in the energy-saving state. The present application embodiment does not limit this.

[0104] In actual application, the terminal can send a first signal to request the first network node to send an SSB; or, the terminal can send a first channel to request the first network node to send an SSB; or, the terminal can send a first signal and a first channel simultaneously to request the first network node to send an SSB; where the first signal and the first channel are in one transmission block, that is, the terminal sends the first signal and the first channel simultaneously in the form of a transmission block.

[0105] In the New Radio (NR), the terminal and the base station are the two communication parties. All terminals need to synchronize to the serving cell to obtain downlink synchronization and cell configuration information, etc. In the sidelink (SL) scenario, multiple types of synchronization sources are supported. The terminal can select one type of synchronization source and obtain timing information. Then, the terminal can perform SL synchronization based on the synchronization priority type, the synchronization source priority, or the reference signal receiving power (RSRP); among them, the two parties performing SL communication do not necessarily synchronize to each other, nor do they necessarily synchronize to the same synchronization source.

[0106] Exemplarily, assuming that in the SL scenario, two types of synchronization priority types are supported, specifically GNSS-based (Global Navigation Satellite System) and gNB / eNB-based. The synchronization priority type of the terminal is configured by higher-layer parameters or pre-configured, and the priorities of the synchronization sources corresponding to different synchronization priorities are defined differently. Taking the GNSS-based synchronization priority as an example, GNSS corresponds to the highest priority P0. When the terminal can directly synchronize to GNSS, the synchronization priority of the terminal is P1. Additionally, when the terminal can search for multiple synchronization sources, it can select the synchronization source with a higher priority as the reference synchronization source; if the priorities of multiple synchronization sources are the same, it can select the synchronization source with a higher RSRP as the reference synchronization source. Among the synchronization sources defined in SL, there is a reference terminal, that is, one terminal can send S-SSB, and other terminals can search for the S-SSB and select the terminal that sends the S-SSB (i.e., the reference terminal) as the synchronization source.

[0107] The configuration information of the S-SSB is as follows: On a carrier for SL communication (SL carrier), the configuration information may include the start position of the SL bandwidth part (BWP), the bandwidth of the SL BWP, the frequency-domain position of the S-SSB, the synchronization priority, and the synchronization configuration information (such as the S-SSB time-domain configuration information), etc.; among them, as Figure 2 shown, an S-SSB can occupy 132 consecutive subcarriers in the frequency domain (i.e., 11 physical resource blocks (PRBs)), and the SL BWP includes the frequency-domain position and the transmission bandwidth of the S-SSB.

[0108] Among them, regarding the time-domain configuration information of the S-SSB, as Figure 3As shown, it can be configured by high-layer parameters. Among them, the time-domain configuration information may include a period (such as 160 ms), the number of S-SSBs within one period (which can be expressed as ), a slot offset (i.e., the slot offset from the first slot to the first S-SSB appearing within this slot, which can be expressed as ), a slot interval (i.e., the slot interval between S-SSBs, which can be expressed as ), etc. Additionally, one S-SSB can occupy 13 orthogonal frequency-division multiplexing (OFDM) symbols (corresponding to the normal cyclic prefix (CP)) or 11 OFDM symbols (corresponding to the extended CP) in the time domain; among them, the slot of the S-SSB may include the sidelink primary synchronization signal (S-PSS) and the sidelink secondary synchronization signal (S-SSS). Taking the normal CP as an example, as Figure 4 shown, the slot structure of one S-SSB may include S-PSS, S-SSS, and PSBCH.

[0109] Based on the configuration information of the SSB on the carrier, the terminal can send S-SSB; among them, in the SL scenario, the transmission conditions and transmission rules of S-SSB are defined. Exemplarily, assume that the frequency band for the terminal to perform SL communication is out-of-coverage, and the synchronization source selected by the terminal is GNSS. When the terminal is in the radio resource control (RRC) connected state and the sidelink synchronization signal (SLSS) transmission field in the dedicated signaling is set to 0, the terminal can send the synchronization signal.

[0110] It can be seen from the above description that in the SL scenario, when the timing information is not obtained by relying on other cells, the terminal can still send the synchronization signal. This SL mechanism provides a reference basis for the terminal to send WUS to wake up the base station.

[0111] In an embodiment of the present application, a new signal or channel may be newly defined based on the above-mentioned SL mechanism to request the first network node to send an SSB (which can also be understood as waking up the first network node) through the newly defined signal or channel. In this way, in scenario B described above, the terminal can send an SSB to the network node without relying on other cells. Of course, the newly defined signal or channel is also applicable to scenario A described above.

[0112] Based on this, in one embodiment, the sending of the first signal and / or the first channel includes:

[0113] Obtain seventh information, where the seventh information includes configuration information of the first signal and / or the first channel;

[0114] Use the configuration information to send the first signal and / or the first channel.

[0115] Among them, the seventh information may be high-layer parameter configuration or pre-configured or protocol-defined (i.e., predefined). That is to say, the terminal can obtain the seventh information through high-layer parameters. The seventh information may also be pre-configured information, and the seventh information may also be protocol-defined information. The present application embodiment does not limit the acquisition method of the seventh information.

[0116] Here, in actual application, when the seventh information includes configuration information of the first signal, the terminal can use the configuration information of the first signal to send the first signal; when the seventh information includes configuration information of the first channel, the terminal can use the configuration information of the first channel to send the first channel; when the seventh information includes configuration information of the first signal and the first channel, the terminal can use the configuration information of the first signal and the first channel to send the first signal and the first channel.

[0117] In one embodiment, the configuration information includes one or more of the following (which can also be understood as at least one or at least one item):

[0118] Time-domain configuration information of the first signal and / or the first channel;

[0119] Frequency-domain configuration information of the first signal and / or the first channel;

[0120] Priority information of the first signal and / or the first channel;

[0121] Start symbol and / or symbol length of the first signal and / or the first channel within a time slot;

[0122] Association relationship between the first signal and / or the first channel and one or more network nodes.

[0123] Among them, the frequency-domain configuration information may include the frequency-domain positions of one or more first signals and one or more first channels in a specific carrier frequency point; the priority information may be understood as the transmission priority of the first signal and / or the first channel; the association relationship between the first signal and / or the first channel and one or more network nodes may be understood as the association relationship between the resources (such as time-domain resources, code-domain resources, or frequency-domain resources) of the first signal and / or the first channel and one or more network nodes.

[0124] In one embodiment, the time-domain configuration information includes one or more of the following:

[0125] Transmission period (which can be expressed in English as Periodicity);

[0126] Slot offset (which can be expressed in English as Slot Offset);

[0127] The number of transmission opportunities within one period (which can be expressed in English as Number);

[0128] Time interval (which can be expressed in English as Inteval).

[0129] Among them, the slot offset can be understood as the slot offset from the start of one period to the first first signal and / or the first channel; the number of transmission opportunities within one period can be understood as the number of the first signal and / or the first channel; the time interval can be understood as the slot interval between every two transmission opportunities.

[0130] Exemplarily, as Figure 5 shown, the time-domain configuration information (which can be called time-domain allocation information) and the frequency-domain configuration information (i.e., frequency-domain position) of the first signal and / or the first channel are defined; among them, the number of transmission opportunities within one period can be defined as 4, that is, there are 4 transmission opportunities within one period.

[0131] In one embodiment, one transmission opportunity includes one or more of the following:

[0132] First signal;

[0133] First channel;

[0134] AGC resource;

[0135] Guard interval (which can be expressed in English as GAP).

[0136] Among them, one transmission opportunity can be configured by a high-layer parameter, or one transmission opportunity can be pre-configured, or one transmission opportunity can be defined by a protocol. The embodiments of the present application do not limit this.

[0137] Here, in the field of wireless communication, the variation range of the input signal of a receiver is often very large, and this variation range is called the dynamic range of the receiver. Among them, the influencing factors of the input signal can include the power of the transmitting station, the distance between the receiver and the transmitting station, changes in the transmission environment, etc. To avoid overload caused by excessive input signal intensity, it is necessary to increase the dynamic range of the receiver. Therefore, it is necessary to set up an AGC circuit so that the gain of the amplifier circuit can be adjusted according to the intensity change of the input signal. In this case, the AGC resources (specifically, AGC symbols) in one transmission opportunity are used to indicate the completion of the adjustment by the AGC circuit.

[0138] In practical applications, when one transmission opportunity includes a first signal, the first signal can occupy one or more consecutive or non - consecutive symbols; when one transmission opportunity includes a first channel, the first channel can occupy one or more consecutive or non - consecutive symbols; when one transmission opportunity includes a guard interval, the guard interval can occupy one or more symbols.

[0139] Exemplarily, as Figure 6 shown, assume that one transmission opportunity includes a first signal (which can be called a reference signal or a preamble sequence), a first channel, AGC resources, and a guard interval. The first signal occupies N1 (for example, 4) symbols. The N1 symbols can be repetitions of N1 first signals, or the N1 symbols include M1 resources of the first signal, and each resource of the first signal occupies N1 / M1 symbols. The first channel occupies N2 (for example, 8) symbols. The N2 symbols can be repetitions of N2 first channels, or the N2 symbols include M2 resources of the first channel, and each resource of the first channel occupies N2 / M2 symbols. In addition, the first symbol for AGC in each time slot (which can be understood as AGC resources) is a repetition of the second symbol, or the first symbol is a repetition of the first symbol of the first signal, or the first symbol is a repetition of the first symbol of the first channel; after the last first signal or the first channel in one time slot, there are N3 (for example, 1) symbols as the guard interval.

[0140] In practical applications, the terminal can also multiplex relevant uplink reference signals (such as RACH resources) to request the first network node to send SSB; among them, the multiplexed uplink reference signal is applicable to the above - described scenario A.

[0141] Based on this, in one embodiment, the sending of the first signal and / or the first channel includes:

[0142] Using RACH resources to send the first signal and / or the first channel.

[0143] Here, the terminal can obtain one or more dedicated RACH resources and send the first signal and / or the first channel. The RACH resources can include RACH occasions, RACH preambles, etc. Embodiments of the present application do not limit the type of RACH resources.

[0144] In practical applications, during the process of sending the first signal and / or the first channel, the terminal can select a synchronization source and obtain timing information from the selected synchronization source; then, based on the obtained timing information, send the first signal and / or the first channel; where, in the above-described scenario A, the synchronization source can include GNSS, a cell, or a reference UE; in the above-described scenario B, the synchronization source can include GNSS or a reference UE. Embodiments of the present application do not limit the type of synchronization source.

[0145] In practical applications, the terminal can carry auxiliary related information through the first signal and / or the first channel, enabling the first network node to better save energy when providing services for the terminal, that is, the auxiliary related information is used to indicate the network side to perform energy saving.

[0146] Specifically, in one embodiment, the first signal and / or the first channel carry first information.

[0147] In practical applications, if the first signal and / or the first channel are sent using the configuration information, the terminal can carry the first information through the first channel; if the first signal and / or the first channel are sent using RACH resources, the terminal can carry the first information through the first signal (specifically, it can be MsgA or Msg3).

[0148] Where, in one embodiment, the first information can include one or more of the following:

[0149] Second information, where the second information characterizes the type of the terminal; [[ID=rg=19]]

[0150] Third information, where the third information includes the bandwidth information of the terminal;

[0151] Fourth information, where the fourth information includes the buffer information of the terminal;

[0152] Fifth information, where the fifth information includes DRX cycle information;

[0153] Sixth information, where the sixth information includes the area identifier of the terminal.

[0154] Among them, in actual application, the types of the terminal may include enhanced mobile broadband terminals (eMBB UEs), reduced-capability terminals (RedCap UEs), narrowband Internet of Things terminals (IoT UEs), etc. The types of the terminal can be represented by 1 or 2 bits (which can be expressed as "bit" in English); the bandwidth information of the terminal (such as 5 MHz, 10 MHz, or 100 MHz) can be represented by 5 bits; the buffer period of the terminal (which can be expressed as "UE buffer Size" in English) can be represented by 8 bits; the DRX period information can be represented by 5 bits; the area identifier of the terminal (which can be expressed as "zone ID" in English) can be represented by 12 bits.

[0155] Here, when the first information includes the second information, the network side can configure (which can be understood as enabling) appropriate bandwidth resources (such as 20 MHz) for the terminal according to the type of the terminal (such as a reduced-capability terminal), so as to avoid waste of bandwidth resources; when the first information includes the fourth information or the third information, the network side can configure appropriate bandwidth or schedule appropriate resources for the terminal according to the recommended bandwidth information or cache information of the terminal to achieve network energy saving; when the first information includes the fifth information, the network side can determine discontinuous transmission (DTX, Discontinuous Transmission) or DRX of the cell according to the recommended DRX period of the terminal; when the first information includes the sixth information, the network side can perform energy-saving enhancement in the airspace according to the geographical location of the terminal.

[0156] Exemplarily, as Figure 7 shown, after the terminal obtains its own location information (such as the coordinates of the Global Positioning System (GPS)), it uses its own location information to determine that the corresponding area identifier is 6 (that is, the zone ID is 6), and reports the area identifier to the network side; after receiving the area identifier, the network side can only turn on the beam in the direction corresponding to the area identifier.

[0157] In actual application, the terminal can also indicate the first information through the first signal and / or the first channel.

[0158] In an embodiment, the first signal and / or the first channel indicate the first information; wherein, the first information is indicated by one or more of the following:

[0159] The frequency-domain configuration information of the first signal and / or the first channel;

[0160] Time-domain configuration information of the first signal and / or the first channel;

[0161] Sequence ID of the first signal (which can be expressed in English as sequence ID);

[0162] Cyclic shift of the first signal (which can be expressed in English as cyclic shift).

[0163] In actual applications, in the scenario where the first signal and / or the first channel indicates the first information, the indication rule can be configured in a pre-configured or protocol-defined manner so as to indicate the first information based on the indication rule; that is to say, the time-domain resources, frequency-domain resources, and code-domain resources (such as sequence ID or cyclic shift) of the first signal and / or the first channel can jointly indicate the first information.

[0164] Exemplarily, assume that the frequency-domain configuration information of the first signal and / or the first channel includes 5 frequency-domain positions (the first frequency-domain position, the second frequency-domain position, the third frequency-domain position, the fourth frequency-domain position, and the fifth frequency-domain position), the time-domain configuration information includes 3 time-domain positions (the first time-domain position, the second time-domain position, and the third time-domain position), and the code-domain resources of the first signal include 6 sequence IDs (the first sequence ID, the second sequence ID, the third sequence ID, the fourth sequence ID, the fifth sequence ID, and the sixth sequence ID). Then, based on the indication rule, the first frequency-domain position, the first time-domain position, and the first sequence ID of the first signal and / or the first channel can jointly indicate that the UE type is eMBB UE, the bandwidth is 20 MHz, and the DRX period is 40 ms; or, the second frequency-domain position, the first time-domain position, and the first sequence ID of the first signal and / or the first channel can jointly indicate that the UE type is RedCap UE, the bandwidth is 20 MHz, and the DRX period is 40 ms; or, the third frequency-domain position, the second time-domain position, and the first sequence ID of the first signal and / or the first channel can jointly indicate that the UE type is eMBB UE, the bandwidth is 40 MHz, and the DRX period is 40 ms.

[0165] In actual applications, in order to enable the terminal to know how to send the first signal and / or the first channel, the sending behavior of the terminal can be defined.

[0166] Specifically, in one embodiment, the sending of the first signal and / or the first channel includes:

[0167] Sending the first signal and / or the first channel on one or more transmission opportunities;

[0168] Or,

[0169] Send the first signal and / or the first channel on different transmission opportunities using different spatial domain transmission filters.

[0170] In practical applications, the transmission behavior of the terminal can be predefined, or the terminal can determine the transmission behavior of the terminal according to the priority information of the first signal and / or the first channel. The embodiments of the present application do not limit the manner of determining the transmission behavior.

[0171] In practical applications, the terminal can send the first signal and / or the first channel on one transmission opportunity, or the terminal can send the first signal and / or the first channel on multiple transmission opportunities, that is, the terminal can perform repeated transmission on multiple transmission opportunities.

[0172] In practical applications, the terminal can also send the first signal and / or the first channel on different transmission opportunities using different spatial domain transmission filters; that is to say, the terminal uses the beam polling method to send the first signal and / or the first channel on the corresponding transmission opportunities.

[0173] Here, when the terminal sends the first signal and / or the first channel, multiple network nodes in the area may be woken up when detecting the first signal and / or the first channel and provide services for the terminal. However, the terminal may only need a specific network node (such as the first network node) to provide services for the terminal. In this way, the energy consumption of the network node will increase.

[0174] To solve the above problems, the transmission behavior of the terminal can be optimized to achieve energy saving gain for the network. Specifically, when the configuration information includes the association relationship between the first signal and / or the first channel and one or more network nodes, the terminal can send the first signal and / or the first channel corresponding to the first network node based on the above association relationship; correspondingly, the first network node can listen on the resources of the corresponding first signal and / or the first channel. In this way, it can ensure that the terminal sends the first signal and / or the first channel to a specific network node (i.e., the first network node) to wake up the specific network node (i.e., request the specific network node to send the SSB).

[0175] Correspondingly, the embodiments of the present application also provide a transmission method applied to the first network node, as Figure 8 shown. The method includes:

[0176] Step 801: Receive the first signal and / or the first channel, where the received first signal and / or the first channel are used to request the first network node to send the SSB;

[0177] Step 802: Send the SSB.

[0178] In practical applications, in order to achieve energy-saving gains on the network side, the receiving behavior of network nodes can be optimized to reduce the energy consumption of network nodes.

[0179] Specifically, in one embodiment, the sending of the SSB includes:

[0180] Negotiate with other network nodes except the first network node to obtain a negotiation result;

[0181] When the negotiation result indicates that the first network node is awakened, send the SSB.

[0182] In practical applications, if multiple network nodes in the area all receive (which can be understood as listening) the first signal and / or the first channel, each network node can inform other network nodes through the backhaul link and conduct negotiations to obtain a negotiation result; among them, the negotiation result can be obtained based on the resource situation of the network nodes.

[0183] When the negotiation result indicates that the first network node is awakened, the first network node can be awakened and send the SSB, so as to provide services for the terminal; other network nodes except the first network node will not be awakened. In this way, the energy consumption of network nodes is reduced, thereby achieving energy-saving gains on the network.

[0184] In practical applications, the network side can also pre-configure or define the wake-up priority of network nodes, so as to determine the receiving behavior of network nodes based on the wake-up priority.

[0185] In one embodiment, the sending of the SSB includes:

[0186] Based on the eighth information, determine that the first network node is awakened, and the eighth information includes the wake-up priorities of one or more network nodes;

[0187] Send the SSB.

[0188] In practical applications, if multiple network nodes in the area all hear the first signal and / or the first channel, each network node can determine the awakened network node based on the eighth information; when the first network node is awakened, the first network node can send the SSB.

[0189] Exemplarily, assume that there are 6 network nodes in the area, namely 3 macro stations at 2.6 GHz (A, B, and C) and 3 small stations at 4.9 GHz (D, E, and F). The priority of the macro stations is 0, and the priority of the small stations is 1, that is, the priority of the macro stations is higher than that of the small stations. When network nodes with different priorities (such as macro station B and small station D) simultaneously detect the first signal and / or the first channel, macro station B is preferentially awakened; when network nodes with the same priority (such as macro stations A and C) simultaneously detect the first signal and / or the first channel, the network node with a higher RSRP is preferentially awakened.

[0190] In practical applications, after the first network node sends the SSB, the terminal can achieve downlink synchronization based on the SSB.

[0191] The embodiment of the present application also provides a transmission method, as Figure 9 shown, this method includes:

[0192] Step 901: The terminal sends a first signal and / or a first channel to the first network node;

[0193] wherein, the sent first signal and / or first channel are used to request the first network node to send the SSB.

[0194] Step 902: The first network node sends the SSB.

[0195] Here, it should be noted that: The specific processing procedures of the terminal and the first network node have been described in detail above and will not be elaborated here.

[0196] In the transmission method provided by the embodiment of the present application, the terminal sends a first signal and / or a first channel, and the sent first signal and / or first channel are used to request the first network node to send the SSB. After receiving the first signal and / or the first channel, the first network node sends the SSB. In the technical solution provided by the embodiment of the present application, the terminal enables the first network node (such as a network node in the energy-saving state) to send the SSB by sending the first signal and / or the first channel. That is to say, for a network node in the energy-saving state (which can also be understood as the energy-saving mode), the terminal can send a wake-up signal / wake-up channel to enable the network node to resume the working state (which can also be understood as the working mode), so as to provide services for the terminal.
