Description

Signal sending method, device, terminal and network equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410177408.X and application name “Signal Transmission Method, Device, Terminal and Network Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a signal sending method, apparatus, terminal, and network equipment. Background Art

[0003] In mobile networks, network energy consumption accounts for a significant portion of operating costs. Most of this energy consumption comes from the radio access network, particularly the active antenna unit (AAU). Therefore, research on energy-saving technologies for network energy consumption is urgent.

[0004] Network energy conservation primarily discusses various technologies that help network devices reduce energy consumption from the perspectives of time, frequency, spatial, and power domains. For idle / inactive mode user equipment (UE), supporting on-demand transmission of System Information Block 1 (SIB1) is a key candidate for time-domain network energy conservation. The UE can trigger or request network devices to send SIB1 using an uplink wake-up signal (UL WUS).

[0005] The resource configuration of UL WUS is configured through SIB signaling. For energy-saving cells, when only the synchronization signal block (SSB) is sent without sending SIB messages such as SIB1, the resource configuration of UL WUS cannot be configured through SIB signaling. The terminal cannot obtain the configuration information of UL WUS and cannot send UL WUS on demand. Summary of the Invention

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0363] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0364] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0365] When describing the embodiments of the present disclosure, some concepts used in the following description are first explained.

[0366] 1. On-demand SIB1

[0367] For network energy conservation purposes, a cell may transmit only SSBs without SIB1. This reduces network energy consumption by reducing SIB1 transmission. The UE can trigger the transmission of SIB1 on demand by sending UL WUS when needed. In this case, the UE needs to determine the triggering mechanism and resource location of the UL WUS.

[0368] The UL WUS may be sent to idle / inactive mode UEs. Among the uplink signals or channels that can be sent by existing idle / inactive mode UEs, a primary signal is the random access preamble, and the preamble can be used to request other SIB messages besides SIB1.

[0369] 2. Preamble

[0370] The UE obtains the specific configuration of the random access opportunity (RACH occasion, RO) by decoding the SIB signaling sent by the base station in the current cell. The UE initiates contention-based random access to the cell where it is currently staying, that is, it sends a preamble based on the ZC (Zadoff-chu) sequence to the base station on the RO.

[0371] If the UE has beam reciprocity, the UE can determine a transmit beam based on the receive beam to send the preamble. If the UE does not have beam reciprocity, the UE can only send the preamble in a trial-by-trial manner, that is, uplink beam scanning.

[0372] The base station uses receive beamforming to receive the preamble signal sent by the UE. If beam reciprocity on the base station side is not met, the base station needs to try multiple possible receive beams, that is, use receive beam scanning to receive the signal. If beam reciprocity on the base station side is met, the base station can determine the corresponding receive beam based on the transmit beam.

[0373] Before sending the Preamble, the UE has already determined the associated SSB. The transmit beam of the associated SSB is the best candidate for determining the base station's receive beam. However, at this time, the UE has not informed the base station of the associated SSB corresponding to the sent Preamble. This can be solved by establishing an RO subset and an association between the Preamble and the SSB. After detecting an SSB, the UE selects an RO and a Preamble from the RO subset and Preamble associated with the SSB. The RO and Preamble selected by the UE implicitly indicate the SSB detected by the UE. When the base station detects a specific Preamble on a specific PRACH resource, it can use the transmit beam of the associated SSB to determine the receive beam.

[0374] The association relationship between SSBs and ROs supports 1-to-1, many-to-1, and 1-to-many situations. The specific mapping rules are as follows: The UE reads the high-level parameters and obtains two parameters, A and R, where A represents the number of SSBs associated with a RO; R represents the number of consecutive preambles for contention-based random access corresponding to each SSB. For the contention-based random access process (CBRA), the order in which the SSB index is mapped to the RO index is as follows:

[0375] First, sort in ascending order of Preamble index within a RO;

[0376] Second, the frequency resource indexes of multiple frequency-division-multiplexed ROs are arranged in ascending order;

[0377] Third, according to the increasing order of the time resource index of the time division multiplexing RO within a PRACH time slot;

[0378] Fourth, arrange in ascending order of the PRACH time slot index.

[0379] Embodiments of the present disclosure provide a signal transmission method, apparatus, terminal, and network device to solve the problem that a UE cannot transmit a UL WUS on demand.

[0380] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0381] As shown in FIG1 , an embodiment of the present disclosure provides a signal transmission method, which is applied to a terminal and specifically includes the following steps:

[0382] Step 101: The terminal determines, according to a first rule and / or first indication information sent by a first cell, relevant information of a first uplink signal, where the first uplink signal is used to instruct a second cell to send a first message, where the first message includes: a system information block SIB1 and / or a synchronization signal block SSB;

[0383] Step 102: The terminal sends a first uplink signal according to the relevant information of the first uplink signal.

[0384] In this embodiment, the terminal can determine relevant information about the first uplink signal based on the first rule and / or the first indication information, and can send the first uplink signal on demand. The first rule can be preconfigured or predefined, or configured by a network-side device. The terminal and the first cell and the second cell have the same understanding of the first rule. The first indication information is sent by the first cell.

[0385] In some embodiments, the terminal may determine relevant information of a first uplink signal based on a first rule, where the first uplink signal is used to instruct (and / or wake up) the second cell to send SIB1 and / or SSB.

[0386] In some embodiments, the terminal may determine relevant information about a first uplink signal based on first indication information sent by a first cell. The first uplink signal is used to instruct (and / or wake up) a second cell to transmit SIB1 and / or SSB. In some embodiments, the first cell and the second cell may be the same cell. For example, cell 1 sends first indication information to the terminal, and the terminal determines relevant information about a first uplink signal based on the first indication information. The first uplink signal is used to instruct cell 1 to transmit a first message. The first cell and the second cell may also be different cells. For example, the first cell may be a non-energy-saving cell, and the second cell may be an energy-saving cell. That is, the terminal determines relevant information about a first uplink signal used to wake up another cell based on the indication information of one cell. For example, if the first cell is a non-energy-saving cell and the second cell is an energy-saving cell, the non-energy-saving cell may configure the terminal with relevant information about the first uplink signal corresponding to one or more energy-saving cells using the first indication information. When the terminal wishes to instruct a particular energy-saving cell to transmit SIB1 and / or SSB, it may send the first uplink signal to the energy-saving cell based on the relevant information about the first uplink signal corresponding to the energy-saving cell.

[0387] In some embodiments, the first uplink signal may be a UL WUS signal, and the UL WUS signal may be used to instruct (and / or wake up) one or more second cells to send SIB1 and / or SSB.

[0388] In an embodiment of the present application, the second cell may indicate at least one cell, that is, the second cell may also be considered as a second cell group, which includes at least one second cell. The relevant information of the first uplink signal corresponding to a second cell group may be the same or different.

[0389] In this embodiment, the terminal may send the first uplink signal as needed, and may send the first uplink signal when the terminal desires to instruct (and / or wake up) a second cell to send the first message.

[0390] In an embodiment of the present disclosure, the terminal can determine relevant information of the first uplink signal based on the first rule and / or the first indication information, and the first uplink signal is used to instruct the second cell to send SIB1 and / or SSB. The terminal can send the first uplink signal as needed, thereby triggering the SIB1 and / or SSB of the second cell.

[0391] As an optional embodiment, the relevant information of the first uplink signal includes:

[0392] Used to send relevant information of the first uplink signal to the first cell, and / or used to send relevant information of the first uplink signal to the second cell.

[0393] In this embodiment, the relevant information of the first uplink signal determined by the terminal may be relevant information for sending an uplink signal to the first cell, or may be relevant information for sending an uplink signal to the second cell, wherein the first uplink signal sent by the terminal is used to instruct the second cell to send SIB1 and / or SSB.

[0394] For example, if the terminal sends a UL WUS to the first cell to trigger the second cell to send SIB1, then in this case the terminal sends the UL WUS according to the relevant information used to send the first uplink signal to the first cell.

[0395] If the terminal sends a UL WUS to the second cell to trigger the second cell to send SIB1, in this case the terminal sends the UL WUS according to the relevant information used to send the first uplink signal to the second cell.

[0396] In some embodiments, the first indication information includes: relevant information of the first uplink signals corresponding to N second cells, where N is a positive integer.

[0397] In this embodiment, the first indication information may indicate relevant information of the first uplink signal corresponding to one or more second cells. For example, if the first indication information indicates relevant information of the UL WUS corresponding to 10 energy-saving cells, and the terminal desires to instruct (and / or wake up) cell 1 to send SIB1, the UL WUS may be sent based on the relevant information of the UL WUS corresponding to cell 1.

[0398] As an optional embodiment, the relevant information of the first uplink signal includes at least one of the following:

[0399] (1) sequence-related information of first uplink signals corresponding to N second cells, where each second cell corresponds to a group of sequence-related information of first uplink signals;

[0400] In this embodiment, the terminal may determine sequence-related information of the first uplink signal corresponding to one or more second cells. Each second cell corresponds to a set of sequence-related information of the first uplink signal, i.e., N second cells correspond to N sets of sequence-related information of the first uplink signal. The parameters included in each set of sequence-related information of the first uplink signal may be the same or different.

[0413] 3) The number of target first uplink signal sequences corresponding to the first uplink signal opportunity, where the target first uplink signal is a first uplink signal used to indicate M second cells, where M is a positive integer. In some embodiments, the sequences of the first uplink signals of the M second cells indicated in the target first uplink signal are different, i.e., the number of target first uplink signal sequences is the total number of different sequences of the first uplink signals of the M second cells; alternatively, the sequences of the first uplink signals indicating the M second cells in the target first uplink signal are the same, and the same sequence can be used to indicate the M second cells.

[0414] In this embodiment, the first indication information may include resource-related information of the first uplink signal, such as one or more of the above items.

[0452] As an optional embodiment, the terminal may further determine relevant information of the first uplink signal based on the first rule.

[0453] In some embodiments, the first rule includes at least one of the following:

[0454] The number of first uplink signal opportunities corresponding to the second cell is related to the number of SSBs;

[0455] The number of first uplink signal opportunities corresponding to the second cell is related to the number of SSBs corresponding to one first uplink signal opportunity;

[0456] The number of first uplink signal opportunities corresponding to the second cell is related to the number of first uplink signal opportunities corresponding to one SSB.

[0457] Here, the number of SSBs can be understood as the number of SSBs in different beam directions. For example, the number of SSBs in different beam directions is 8. In this case, the number of SSBs is 8.

[0458] In this embodiment, each second cell may correspond to L first uplink signal opportunities. An SSB may correspond to multiple beam directions. L first uplink signal opportunities are required to complete one round of mapping between the first uplink signal and SSBs in different beam directions. The terminal may determine the number of first uplink signal opportunities corresponding to the second cell based on the number of SSBs, the number of SSBs corresponding to one first uplink signal opportunity, and / or the number of first uplink signal opportunities corresponding to one SSB.

[0459] In some embodiments, the number of SSBs includes: the number of SSBs of the first cell;

[0460] and / or

[0461] The number of SSBs of the second cell.

[0462] In some embodiments, if the terminal sends the first uplink signal to the first cell, the number of SSBs is the number of SSBs of the first cell;

[0463] If the terminal sends the first uplink signal to the second cell, the number of SSBs is the number of SSBs of the second cell.

[0464] In some embodiments, when the number of SSBs is the number of SSBs of the second cell, the first indication information may also include the number of SSBs of the second cell.

[0465] As an optional embodiment, determining, according to the first rule, relevant information of the first uplink signal includes:

[0466] The relevant information of the first uplink signal includes the first uplink signal opportunity, and the first uplink signal opportunity corresponding to the second cell is determined according to the number of first uplink signal opportunities corresponding to the second cell and / or the identifier of the second cell; wherein the identifier of the second cell is: the identifier of a second cell among N second cells.

[0467] In this embodiment, the terminal may determine the first uplink signal opportunity corresponding to the second cell according to the first rule. In some embodiments, the first uplink signal opportunity corresponding to the second cell may be determined according to the number of first uplink signal opportunities corresponding to the second cell and / or the identifier of the second cell. The identifier of the second cell is: an identifier of a second cell among N second cells, for example: the identifier of the first second cell among N second cells is 0 (identification starts from 0), or the identifier of the first second cell among N second cells is 1 (identification starts from 1).

[0468] In some embodiments, determining the first uplink signal opportunity corresponding to the second cell according to the number of first uplink signal opportunities corresponding to the second cell and the identifier of the second cell includes:

[0469] determining, according to the number of first uplink signal opportunities corresponding to the second cell and the identifier of the second cell, a first uplink signal opportunity corresponding to the second cell within the first time;

[0470] The first time includes N*L first uplink signal opportunities, N is the number of the second cells, L is the number of first uplink signal opportunities corresponding to one of the second cells, and both N and L are positive integers.

[0471] In some embodiments, for the target second cell among the N second cells, the identifier of the first uplink signal opportunity corresponding to the target second cell within the first time and the first uplink signal opportunity included in the first time satisfies: I*L+{0,,1,…,L-1} or, I*L+{1,…,L}; wherein I is the identifier of the target second cell.

[0472] In some embodiments, L can be the number of first uplink signal opportunities in the time domain corresponding to the second cell. For example, a second cell corresponds to 8 first uplink signal opportunities, and there are 2 frequency-divided opportunities in the frequency domain. Then the number of first uplink signal opportunities corresponding to a second cell in the time domain is 4.

[0473] In this embodiment, the terminal can determine the identifier of the first uplink signal opportunity corresponding to a second cell within a time period (i.e., the first time period) according to the first rule. For example, if the identifier of the target second cell among N second cells is I, and the identifier of the first uplink signal opportunity corresponding to the second cell I within the first time period is S, then S is I*L+{0,,1,…,L-1} (identification starts from 0) or I*L+{1,…,L} (identification starts from 1).

[0474] As an optional embodiment, sending the first uplink signal according to the relevant information of the first uplink signal includes at least one of the following:

[0475] sending a first uplink signal to the first cell according to relevant information of the first uplink signal;

[0476] The first uplink signal is sent to a target second cell according to relevant information of the first uplink signal, where the target second cell is the second cell indicated by the first uplink signal to send the first message.

[0477] In this embodiment, the terminal may send a first uplink signal to the first cell when it expects to instruct (and / or trigger) the target second cell to send a first message. In some embodiments, the terminal sends the first uplink signal to the first cell based on relevant information used to send the first uplink signal to the first cell; after the first cell receives the first uplink signal, it sends indication information to the target second cell based on the first uplink signal, instructing the target second cell to send the first message.

[0478] For example, if the first cell is a non-energy-saving cell and the target second cell is an energy-saving cell, after receiving the UL WUS, the non-energy-saving cell sends a request message to the energy-saving cell, requesting the energy-saving cell to send SIB1. The energy-saving cell may send a response message to the non-energy-saving cell, where the response message may include confirmation of sending SIB1 and / or refusal to send SIB1, and may also include SIB1 scheduling information. The non-energy-saving cell may confirm whether the energy-saving cell sends SIB1 based on the response message.

[0479] And / or, when the terminal expects to instruct (and / or trigger) the target second cell to send a first message, the terminal can send a first uplink signal to the target second cell. In some embodiments, the terminal sends the first uplink signal to the second cell based on the relevant information for sending the first uplink signal to the second cell; after the second cell receives the first uplink signal, it sends the first message.

[0480] In some embodiments, the first cell and the second cell may further exchange information related to the first uplink signal. For example, the second cell requests information related to the first uplink signal from the first cell; the first cell sends information related to the first uplink signal to the second cell based on the request; and the second cell may further send confirmation information to the first cell to confirm receipt of information related to the first uplink signal.

[0481] In some embodiments, if the first uplink signal is an uplink signal associated with a first beam direction, the second cell sends the first message according to the first beam direction.

[0482] In this embodiment, if the second cell receives a first uplink signal associated with a certain SSB beam direction for triggering a first message, the second cell sends the first message according to the beam direction of the SSB. Alternatively, the first cell receives a first uplink signal sent by the terminal, the first uplink signal is associated with a certain beam direction of the SSB of the first cell, and the first cell determines the associated beam direction of the SSB of the first cell based on the first uplink signal. The first cell determines the beam direction of the SSB of the second cell based on the beam direction of the SSB of the first cell, and the first cell instructs the second cell to send the first message according to the determined beam direction of the SSB.

[0483] As an optional embodiment, the method further includes: determining the state of the second cell according to the first rule and / or the first indication information.

[0484] In this embodiment, the terminal may also determine the state of the second cell based on the first rule and / or the first indication information of the first cell. When the first cell and the second cell are different, the terminal determines the state of one cell based on the indication of the other cell.

[0485] In some embodiments, the method further includes: sending a first uplink signal when the second cell is in a first state according to the state of the second cell, wherein the first uplink signal is used to instruct the second cell to send a first message in the first state.

[0486] In some embodiments, the state of the second cell and / or the first state includes at least one of the following:

[0487] Network energy-saving status;

[0488] A state in which the cell does not send the first message;

[0489] Status of the cell sending the first message on demand;

[0490] The state where only SSB is sent but SIB1 is not sent;

[0491] The cell is in a state of sending the first message according to the first period.

[0492] The following example illustrates the implementation process of the signal sending method according to the embodiment of the present disclosure.

[0493] Example 1: Taking the first uplink signal as UL WUS, the first message as SIB1, the first cell as a non-energy-saving cell, and the second cell as an energy-saving cell as an example, the UE sends a UL WUS to the non-energy-saving cell to instruct the energy-saving cell to send SIB1.

[0494] Step 11: The UE determines the relevant information of the UL WUS based on the first indication information and / or the first rule, and the non-energy-saving cell (first cell) sends the first indication information. The first indication information and / or the first rule are used to determine the relevant information of the UL WUS corresponding to N energy-saving cells, where N is a positive integer. The first uplink signal is used to trigger the energy-saving cell to send SIB1.

[0495] In some embodiments, the UL WUS signal may reuse an existing signal. For example, the UL WUS signal may be a random access preamble; and the first message may be SIB1.

[0496] The relevant information of the UL WUS may be relevant information for sending the UL WUS to the non-energy-saving cell. After the UE obtains the relevant information of the UL WUS, if the UE expects to send a UL WUS indication or wake up a certain energy-saving cell (such as energy-saving cell 1) to send SIB1, the UE sends the UL WUS to the non-energy-saving cell, and the sequence and / or resource configuration of the UL WUS is determined by the relevant information of the UL WUS corresponding to the energy-saving cell 1. That is, there are N UL WUS resources / resource sets corresponding to N energy-saving cells on the non-energy-saving cell. The non-energy-saving cell can know which energy-saving cell the UE wants to wake up to send SIB1 based on the resources / resource sets of the received UL WUS.

[0497] In some embodiments, the UL WUS related information may include at least one of the following:

[0498] (1) Sequence-related information of UL WUS corresponding to N energy-saving cells, where each energy-saving cell corresponds to a set of sequence-related information of UL WUS;

[0499] In this embodiment, M energy-saving cells correspond to one UL WUS opportunity, M may be greater than or equal to 1, or less than 1; when M is greater than or equal to 1, it indicates that at least one energy-saving cell corresponds to one UL WUS opportunity; when M is less than 1, it indicates that one energy-saving cell corresponds to multiple UL WUS opportunities.

[0500] Assume that the SSB includes 8 beams, with a total of 64 UL WUS sequences. Two energy-saving cells correspond to one UL WUS opportunity (M = 2). Sequences 1 to 32 are the UL WUS sequences corresponding to energy-saving cell 1, and sequences 33 to 64 are the UL WUS sequences corresponding to energy-saving cell 2. Each SSB beam direction corresponds to four UL WUS sequences.

[0501] When the first indication information includes M (the number of energy-saving cells corresponding to one UL WUS opportunity) and the total number of UL WUS sequences corresponding to one UL WUS opportunity for indicating M energy-saving cells, and M is greater than or equal to 1, the UE can derive the number of UL WUS sequences corresponding to each energy-saving cell;

[0502] In this case, the first indication information sent by the non-energy-saving cell may include at least one of the following parameters:

[0503] The number of consecutive UL WUS sequences corresponding to each energy-saving cell;

[0504] The index of the UL WUS sequence corresponding to each energy-saving cell;

[0505] The number of consecutive UL WUS sequences corresponding to each SSB of an energy-saving cell;

[0506] The index of the UL WUS sequence corresponding to each SSB of an energy-saving cell.

[0507] (2) Resource-related information of UL WUS corresponding to N energy-saving cells, where each energy-saving cell corresponds to a group of resource-related information of UL WUS.

[0508] In this case, the first indication information sent by the non-energy-saving cell may include at least one of the following parameters:

[0509] The number of energy-saving cells corresponding to one UL WUS opportunity;

[0510] The number of UL WUS opportunities corresponding to the energy-saving cell;

[0511] The number of target UL WUS sequences corresponding to the UL WUS opportunity, where the target UL WUS is used to indicate the UL WUSs of M second cells, where M is a positive integer.

[0512] In some embodiments, N energy-saving cells correspond to P time domain ranges, each of the time domain ranges includes at least one UL WUS opportunity corresponding to the energy-saving cell; each of the P time domain ranges is different;

[0513] and / or,

[0514] N energy-saving cells correspond to Q frequency domain ranges, each of the frequency domain ranges includes at least one UL WUS opportunity corresponding to the energy-saving cell; and each of the Q frequency domain ranges is different.

[0515] Among them, for N energy-saving cells corresponding to P time domain ranges, the first indication information sent by the first cell can indicate information of P time domain ranges, and the UL WUS opportunities contained in each time domain range can be UL WUS opportunities corresponding to multiple energy-saving cells. For example, as shown in Figure 2, the 4 UL WUS opportunities contained in time domain range 1 are UL WUS opportunities corresponding to energy-saving cell 1 and energy-saving cell 2; the 4 UL WUS opportunities contained in time domain range 2 are UL WUS opportunities corresponding to energy-saving cell N-1 and energy-saving cell N.

[0516] In some embodiments, the first indication information sent by the non-energy-saving cell indicates P time domain ranges corresponding to the energy-saving cell, and the time domain range may be a time period or a time window. The first indication information indicated by the non-energy-saving cell may include at least one of the following parameters:

[0517] a starting position of each time domain range in the P time domain ranges;

[0518] an end position of each time domain range in the P time domain ranges;

[0519] The length of each time domain range in the P time domain ranges;

[0520] The number of first uplink signal opportunities contained in each time domain range of the P time domain ranges;

[0521] an identifier of each of the P time domain ranges within the P time domain ranges;

[0522] The starting positions of the P time domain ranges;

[0523] The end positions of the P time domain ranges.

[0524] Each time domain range needs to include a UL WUS transmission opportunity capable of completing at least one round of UL WUS and SSB mapping, and one time domain range may support multiple rounds of UL WUS and SSB mapping.

[0525] The mapping of UL WUS opportunities to SSBs may be performed based on a first rule. The first rule may be at least one of the following:

[0526] The number of UL WUS opportunities corresponding to the energy-saving cell is related to the number of SSBs;

[0527] The number of UL WUS opportunities corresponding to an energy-saving cell is related to the number of SSBs corresponding to one UL WUS opportunity;

[0528] The number of UL WUS opportunities corresponding to the energy-saving cell is related to the number of UL WUS opportunities corresponding to one SSB.

[0529] In this embodiment, the number of UL WUS opportunities corresponding to each energy-saving cell depends on the number of SSBs (different beams) and / or the number of SSBs corresponding to one UL WUS opportunity; alternatively, the number of UL WUS opportunities corresponding to each energy-saving cell is the number of UL WUS opportunities required to complete one round of mapping between UL WUS and SSB.

[0530] The UE may determine the UL WUS opportunities corresponding to the energy-saving cell within the first time period based on the first rule. The first time period includes N*L UL WUS opportunities, and the UE needs to determine the position of the L UL WUS opportunities corresponding to each energy-saving cell in the N*L UL WUS opportunities according to the identifier of the energy-saving cell.

[0531] In the case where the UE sends a UL WUS to a non-energy-saving cell, the UE may determine the number of UL WUS opportunities required to complete one round of mapping according to the number of SSBs of the non-energy-saving cell and the number of SSBs corresponding to one UL WUS opportunity.

[0532] The first time includes N*L UL WUS opportunities. L UL WUS opportunities are required to complete a round of mapping between UL WUS and SSB. Each cell corresponds to L UL WUS opportunities. After an energy-saving cell corresponds to mapping L UL WUS opportunities, the next energy-saving cell corresponds to L UL WUS opportunities, and the cycle continues in sequence, as shown in Figure 3.

[0533] In some embodiments, the first indication information may also indicate Q frequency domain ranges corresponding to N energy-saving cells, and each frequency domain range includes at least one UL WUS opportunity corresponding to the energy-saving cell.

[0534] In this case, the first indication information may include at least one of the following:

[0535] A starting position of each frequency domain range in the Q frequency domain ranges;

[0536] an end position of each frequency domain range in the Q frequency domain ranges;

[0537] The number of UL WUS opportunities contained in each frequency domain range of the Q frequency domain ranges;

[0538] The number of frequency domain resource units contained in each frequency domain range of the Q frequency domain ranges;

[0539] An identifier of each frequency domain range in the Q frequency domain ranges within the Q frequency domain ranges;

[0540] The starting positions of the Q frequency domain ranges;

[0541] The end positions of the Q frequency domain ranges.

[0542] In some embodiments, the non-energy-saving cell may further include relevant information of the UL WUS in the first indication information, such as at least one of the following:

[0543] The total number of UL WUS sequence indices corresponding to UL WUS opportunities;

[0544] The cycle of UL WUS resources;

[0545] Resource location of the UL WUS opportunity in the cycle; for example: UL WUS frame, UL WUS subframe number, start symbol, number of UL WUS slots in the UL WUS subframe.

[0546] The index of the preamble used to request SIB1;

[0547] PRACH configuration period;

[0548] The number of SSBs associated with an RO;

[0549] The number of consecutive preambles corresponding to each SSB;

[0550] PRACH time domain configuration information; used to determine the PRACH resources within the PRACH configuration period, such as the PRACH frame, PRACH subframe number, start symbol, and the number of PRACH slots in the PRACH subframe;

[0551] The number of ROs contained in the PRACH slot;

[0552] Duration of RO;

[0553] UL WUS configuration index; the correspondence between the UL WUS configuration index and the UL WUS configuration resource may be predefined. After the UL WUS configuration index is determined, the UL WUS configuration resource may be determined;

[0554] The configuration index of the PRACH may predefine the corresponding relationship between the PRACH configuration index and the PRACH configuration resource. After the PRACH configuration index is determined, the PRACH configuration resource may be determined.

[0555] Step 12: The UE sends a UL WUS according to the relevant information of the first uplink signal.

[0556] The UE determines the energy-saving cell that needs to be awakened, and can send UL WUS at the resource location of the UL WUS corresponding to the energy-saving cell. The UE can send UL WUS to the non-energy-saving cell. When the non-energy-saving cell detects UL WUS at the resource location of UL WUS, the non-energy-saving cell can determine the energy-saving cell that the UE wants to indicate (or wake up) by the resource location and / or the sequence of UL WUS, and send SIB1 to it. The non-energy-saving cell can exchange information with the energy-saving cell that the UE wants to indicate (or wake up), and the interaction process is, for example:

[0557] The contactless energy-saving cell sends a request message to the energy-saving cell, requesting the energy-saving cell to send SIB1;

[0558] The energy-saving cell may send a response message to the request message to the non-energy-saving cell. The response message may include confirmation of sending SIB1 and / or refusal to send SIB1. The response message may also include a scheduling message of SIB1.

[0559] The non-energy-saving cell confirms whether the energy-saving cell sends SIB1 through the response message.

[0560] In this embodiment, the relevant information of the UE sending UL WUS is determined by the first indication information or the first rule. The relevant information of the UL WUS may include the relevant information of the UL WUS corresponding to N energy-saving cells. When the UE expects to instruct (and / or wake up) a certain energy-saving cell to send SIB1, the UE selects the relevant information of the UL WUS corresponding to the energy-saving cell and sends the UL WUS to the non-energy-saving cell, so that the UE can instruct (and / or wake up) the energy-saving cell to send SIB1 as needed without affecting the UE's service.

[0561] Example 2: Taking the first uplink signal as UL WUS, the first message as SIB1, the first cell as a non-energy-saving cell, and the second cell as an energy-saving cell as an example, the UE sends a UL WUS to the energy-saving cell to instruct the energy-saving cell to send SIB1.

[0562] Step 21: The UE determines the UL WUS information based on the first indication information and / or the first rule, and the non-energy-saving cell (first cell) sends the first indication information. The first indication information and / or the first rule are used to determine the relevant information of the UL WUS corresponding to N energy-saving cells, where N is a positive integer. The UL WUS is used to trigger the energy-saving cell to send SIB1; the first indication information can be a SIB message.

[0563] The UL WUS signal may be a multiplexed signal. For example, the UL WUS signal may be a random access preamble; and the first message may be SIB1.

[0564] The configuration information of the UL WUS corresponding to the N energy-saving cells is the configuration information of the UL WUS of the energy-saving cells. At this time, after the UE obtains the UL WUS configuration information corresponding to the N energy-saving cells, when the UE wants to send a UL WUS to indicate (and / or wake up) a certain energy-saving cell (energy-saving cell 1) to send SIB1, the UE sends a UL WUS to the energy-saving cell, and the sequence and / or resource configuration of the UL WUS is determined by the configuration information of the UL WUS corresponding to the energy-saving cell 1.

[0565] The energy-saving cell needs to detect the UL WUS sent by the UE, and the premise is that the energy-saving cell can obtain the resource configuration information of the UL WUS. Therefore, after the non-energy-saving cell sends the first indication information indicating the configuration information of the UL WUS corresponding to N energy-saving cells, the non-energy-saving cell also needs to send the UL WUS resource configuration information corresponding to each energy-saving cell to the corresponding energy-saving cell, so that the energy-saving cell can obtain the configuration information of the UL WUS and then detect the UL WUS sent by the UE at the appropriate resource location. The non-energy-saving cell can exchange UL WUS resource configuration information with the energy-saving cell, and the interaction process is, for example, the following centralized method:

[0566] Method 1: The non-energy-saving cell sends UL WUS resource configuration information to the energy-saving cell; the energy-saving cell may send confirmation information corresponding to the UL WUS resource configuration information;

[0567] Mode 2: The energy-saving cell sends UL WUS resource configuration information to the non-energy-saving cell; the non-energy-saving cell may send confirmation information corresponding to the UL WUS resource configuration information;

[0568] Mode 3: The non-energy-saving cell requests the energy-saving cell for UL WUS resource configuration information; the energy-saving cell sends the UL WUS resource configuration information to the non-energy-saving cell; the non-energy-saving cell sends confirmation information corresponding to the UL WUS resource configuration information;

[0569] Mode 4: the energy-saving cell requests the non-energy-saving cell for UL WUS resource configuration information; the non-energy-saving cell sends the UL WUS resource configuration information to the energy-saving cell; the energy-saving cell sends confirmation information corresponding to the UL WUS resource configuration information.

[0570] For the configuration information of the UL WUS corresponding to the N energy-saving cells indicated by the first indication information, the specific indication method and parameters are similar to those in Example 1 and are not described in detail here.

[0571] Step 22: The UE sends a UL WUS according to the relevant information of the UL WUS.

[0572] The UE determines the energy-saving cell that it expects to indicate (and / or wake up), and sends a UL WUS at the resource location of the UL WUS corresponding to the energy-saving cell. The UL WUS is sent to the energy-saving cell. When the energy-saving cell detects the UL WUS at the resource location of the UL WUS, the energy-saving cell can determine, through the resource location and / or the sequence of the UL WUS, that the UE expects to indicate (and / or wake up) the energy-saving cell to send SIB1, and the energy-saving cell can decide whether to send SIB1.

[0573] In addition, when the energy-saving cell receives a UL WUS sequence associated with a certain SSB beam direction to trigger the transmission of SIB1, the energy-saving cell transmits SIB1 according to the beam direction of the SSB, that is, SIB1 no longer performs beam scanning, and the transmission direction of SIB1 is related to the transmission direction of the UL WUS sequence.

[0574] In this embodiment, the relevant information of the UE sending the UL WUS is determined by the first indication information or the first rule. The relevant information of the UL WUS may include the relevant information of the UL WUS corresponding to N energy-saving cells. When the UE expects to instruct (and / or wake up) a certain energy-saving cell to send SIB1, the UE selects the relevant information of the UL WUS corresponding to the energy-saving cell and sends the UL WUS to the energy-saving cell, so that the UE can instruct (and / or wake up) the energy-saving cell to send SIB1 as needed without affecting the UE's service.

[0575] In an embodiment of the present disclosure, the terminal can determine relevant information of the first uplink signal based on the first rule and / or the first indication information, and the first uplink signal is used to instruct the second cell to send SIB1 and / or SSB. The terminal can send the first uplink signal as needed, thereby triggering the SIB1 and / or SSB of the second cell.

[0576] As shown in FIG4 , an embodiment of the present disclosure further provides a signal transmission method, which is applied to a first cell. The method includes:

[0577] Step 401: A first cell sends first indication information to a terminal, where the first indication information is used to indicate relevant information of a first uplink signal. The first uplink signal is used to instruct a second cell to send a first message, where the first message includes: SIB1 and / or SSB.

[0578] In this embodiment, the first cell and the second cell may be the same cell or different cells. The first cell sends first indication information to the terminal, and the terminal may determine relevant information of the first uplink signal based on the first indication information, and send the first uplink signal as needed based on the relevant information of the first uplink signal to trigger the second cell to send SIB1 and / or SSB.

[0579] For example, the first cell and the second cell are the same cell. For example, cell 1 sends first indication information to the terminal. The terminal determines relevant information of a first uplink signal based on the first indication information. The first uplink signal is used to instruct cell 1 to send a first message.
