Description

Signal transmission method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on January 23, 2024, with application number 202410095669.7 and application name “Signal Transmission Method and Device,” the entire contents of which are incorporated herein by reference. Technical Field

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

[0003] In related technologies, a connected user equipment (UE) can obtain system information block 1 (SIB1) messages from other cells by having the cell with which the UE is in a radio resource control (RRC) connection forward system messages from other cells. However, this does not apply to UEs in an idle or inactive state because these UEs do not have an RRC connection with the network. Therefore, the network cannot send system messages from neighboring cells to the terminal via RRC messages.

[0142] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0143] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or apparatus.

[0144] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. 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. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.

[0145] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0146] Figure 1 shows a block diagram of a wireless communication system to which the embodiments of the present disclosure can be applied. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. The terminal device 11 may also be referred to as a terminal or a user equipment (UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure. The network-side device 12 may be a base station or a core network. It should be noted that in the embodiments of the present disclosure, only a base station in the NR system is used as an example, but the specific type of the base station is not limited.

[0147] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given.

[0148] (1) Function of SIB1;

[0149] The SIB1 message contains basic information about the cell that the UE can access, such as the Public Land Mobile Network (PLMN), access control information, Random Access Channel (RACH) configuration information, etc. The SIB1 message is sent repeatedly at a certain period.

[0150] (2) Basic concepts of R19 on-demand SIB1 scenario;

[0151] In related technologies, the network always sends SIB1 messages at a predetermined period. SIB1 messages contain basic information that allows UEs to access a cell, such as PLMN and RA configuration information. To save energy on the network side, the base station can disable the transmission of SIB1 messages. This also prevents UEs from staying in the cell, affecting cell coverage and network capacity.

[0152] When the UE is in idle / inactive state, if a cell is in energy-saving state and no SIB1 message is sent, but the UE detects this cell based on the cell's SSB information and wants to access the cell, the cell needs to start the transmission of SBI1 based on a certain trigger mechanism so that the UE can reside in the corresponding cell.

[0153] The signal transmission method provided by the embodiments of the present disclosure is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0154] As shown in FIG2 , an embodiment of the present disclosure provides a signal transmission method, which is performed by a terminal. The method includes:

[0156] In the embodiment of the present disclosure, the wake-up signal configuration information can configure the wake-up signal for a specific cell, a specific frequency, a specific RNA, a specific cell group and / or a specific Area scope, that is, the wake-up signal can be configured for at least one cell through the above wake-up signal configuration information.

[0157] Step 202: Send a wake-up signal to the target cell according to the wake-up signal configuration information, where the wake-up signal is used to request the target cell to send a system information block SIB1 message.

Through the above-mentioned wake-up signal configuration information, a wake-up signal can be configured for at least one cell, and the wake-up signal is used to request the cell to send SIB1, so that after sending a wake-up signal to the target cell based on the wake-up signal configuration information, the target cell can be triggered to send SIB1 to the terminal, thereby achieving the purpose of enabling the terminal in an idle or inactive state to obtain the SIB1 of the target cell (which may be a neighboring cell).

[0176] The number of times the SSB message is repeated in one sending cycle;

[0177] The number of repetitions of the SSB message sending cycle;

[0179] In the embodiment of the present disclosure, the transmission of SIB1 and / or SSB, as well as the transmission parameters of SIB1 and / or SSB (such as transmission resources, transmission period, etc.), etc., can be indicated by the wake-up signal or related parameters of the wake-up signal.

[0180] As an implementation manner, the relevant parameters of the wake-up signal include at least one of a time domain resource of the wake-up signal, a frequency domain resource of the wake-up signal, sequence information of the wake-up signal, and a transmission period of the wake-up signal.

[0181] For example, when the time domain resource of the wake-up signal is resource 1, it is used to indicate that the transmission period of the SIB1 message is period 1; when the time domain resource of the wake-up signal is resource 2, it is used to indicate that the transmission period of the SIB1 message is period 2. For another example, when the sequence information of the wake-up signal is sequence 1, it is used to indicate that the SIB message is sent; when the sequence information of the wake-up signal is sequence 2, it is used to indicate that the SIB message is stopped from being sent.

[0182] In some embodiments, sending a wake-up signal to a target cell according to the wake-up signal configuration information includes:

[0183] When a preset condition is met, sending a wake-up signal to the target cell according to the wake-up signal configuration information;

[0184] The preset conditions include at least one of the following:

[0185] The channel quality of the cell where the terminal resides is lower than and / or equal to a first threshold;

[0186] The signaling quality of the target cell measured by the terminal is higher than and / or equal to a second threshold;

[0187] The target cell meets the conditions for terminal cell selection or reselection;

[0188] The camped cell of the terminal enables the terminal to send a wake-up signal to a specific cell or a specific cell group or a cell in a specific RAN area or a cell in a specific area range;

[0189] The terminal has uplink data to transmit or is ready to access the network;

[0190] The terminal needs to update the SIB1 message of the wake-up cell;

[0191] The terminal receives a system message update indication related to the wake-up cell.

[0192] In an embodiment of the present disclosure, when the above-mentioned preset conditions are met, it may indicate that the terminal needs to reside in or access the above-mentioned target cell. In this case, a wake-up signal is sent to the target cell based on the wake-up signal configuration information, so that the target cell sends SIB1, thereby facilitating the terminal to access or reside in the cell.

[0193] In some embodiments, the wake-up signal includes at least one of a random access (RA) scrambling code, a sounding reference signal (SRS), an SRS positioning reference signal for positioning, and a demodulation reference signal (DMRS).

[0194] In the embodiment of the present disclosure, at least one of the following may be explicitly or implicitly indicated through the time domain resources, frequency domain resources, transmission period, etc. of at least one of RA, SRS, and DMRS:

[0195] SIB1 message sending cycle;

[0196] The number of times the SIB1 message is repeated in one sending cycle;

[0197] The number of repetitions of the SIB1 message sending cycle;

[0198] SIB1 message is sent or stopped;

[0199] SSB message sends or stops sending;

[0200] SSB message sending cycle;

[0201] The number of times the SSB message is repeated in one sending cycle;

[0202] The number of repetitions of the SSB message sending cycle.

[0203] In some embodiments, after sending the wake-up signal to the target cell, the method further includes:

[0204] Receive a SIB1 message sent by the target cell.

[0205] Here, by receiving the SIB1 message sent by the target cell, it is possible to camp on or access the target cell.

[0206] In some embodiments, the SIB1 message satisfies at least one of the following:

[0207] The sending period of the SIB1 message is less than or equal to the sending period indicated by the wake-up signal or a parameter related to the wake-up signal or a predefined value;

[0208] The number of repetitions of the SIB1 message in one transmission cycle is greater than or equal to the number of repetitions of the SIB1 message in the transmission cycle indicated by the wake-up signal or the relevant parameters of the wake-up signal, or a predefined value; for example, if the number of repetitions of the SIB1 message in the transmission cycle indicated by the wake-up signal or the relevant parameters of the wake-up signal is 3 times, then the number of repetitions of the SIB1 message in one transmission cycle may be 4 times or 5 times, etc.;

[0209] The number of repetitions of the sending period of the SIB1 message is higher than or equal to the number of repetitions of the sending period of the SIB1 message indicated by the wake-up signal or the relevant parameters of the wake-up signal or a predefined value; for example, the number of repetitions of the sending period of the SIB1 message indicated by the wake-up signal or the relevant parameters of the wake-up signal is 2 times, then the number of repetitions of the sending period of the SIB1 message can be specifically 3 times, that is, the SIB1 message is sent within 3 sending periods.

[0210] The number of times the SIB1 message is sent is greater than or equal to the number of times the SIB1 message is sent indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value.

[0211] In an embodiment of the present disclosure, after the network side device obtains the wake-up signal, it sends the SIB1 message based on the wake-up signal or the sending parameters of the SIB1 message indicated by the wake-up signal (such as the sending period, the number of repetitions within a sending period, the number of repetitions of the sending period of the SIB1 message, etc.) to ensure that the sending parameters of the sent SIB1 message can meet the sending parameters indicated by the terminal.

[0212] In some embodiments, after sending the wake-up signal to the target cell, the method further includes:

[0213] Obtain a synchronization broadcast block SSB sent by the target cell, where the SSB is sent by the target cell based on the wake-up signal.

[0214] In the embodiment of the present disclosure, after the target cell receives the wake-up signal, if the SSB has not been sent yet, the sending of the SSB can be triggered.

[0215] In some embodiments, if the target cell is an SSB-less cell, the SSB and SIB1 are sent after receiving the wake-up signal.

[0216] In some embodiments, after sending the wake-up signal to the target cell, the method further includes:

[0217] A first timer is started, where the first timer is used to determine whether the target cell fails to wake up.

[0218] Here, based on the first timer, the terminal can determine whether the target wake-up cell fails to be woken up, so as to subsequently adopt corresponding processing operations.

[0219] In some embodiments, the method of the present disclosure further includes:

[0220] If the system information block SIB1 and / or synchronization broadcast block SSB sent by the target cell is not detected within the running time of the first timer, it is determined that the target cell wake-up fails.

[0221] In an embodiment of the present disclosure, after the target wake-up cell receives the wake-up signal, it needs to send SIB1 and / or SSB based on the wake-up signal. If the terminal does not receive SIB1 and / or SSB within a certain period of time, it is determined that the target cell wake-up has failed. By starting the timer, the length of time the terminal waits for the wake-up cell to send SIB1 and / or SSB can be controlled.

[0222] In some embodiments, the method of the present disclosure further includes:

[0223] In the case of determining that the target cell wake-up fails, selecting a wake-up cell other than the target cell from a plurality of wake-up cells to perform a wake-up process.

[0224] Here, in the case where the target wake-up cell fails to wake up, the target wake-up cell may not be successfully awakened within a certain period of time. For example, the channel quality of the target wake-up cell is low within a certain period of time. Therefore, by selecting a wake-up cell other than the target wake-up cell to perform the wake-up process, it is possible to effectively avoid access failure or residence failure caused by an inappropriate wake-up process, thereby improving the success rate of subsequent access and reducing the power consumption of the terminal.

[0225] In some embodiments, the method further comprises:

[0226] If SIB1 and / or SSB sent by the target cell is detected within the running time of the first timer, the first timer is stopped.

[0227] Here, if the SIB1 and / or SSB sent by the target wake-up cell is detected within the running time of the first timer, it is determined that the target wake-up cell is successfully awakened, and the first timer is stopped.

[0228] In some embodiments, the method further comprises:

[0229] During a preset time period, the cell that fails to be awakened is not determined as a wake-up cell and / or a wake-up signal is not sent to the cell that fails to be awakened.

[0230] Here, the cell that failed to be awakened may not be successfully awakened within a certain time period. For example, the channel quality of the cell that failed to be awakened within a certain time period is low. Therefore, by determining the cell that failed to be awakened as the awakening cell within the preset time period and / or not sending a wake-up signal to the cell that failed to be awakened, it is possible to effectively avoid access failure or residence failure caused by an inappropriate wake-up process, thereby improving the success rate of subsequent access and reducing the power consumption of the terminal.

[0231] The signal transmission method disclosed herein is described below with reference to embodiments.

[0232] Embodiment 1: The UE obtains configuration information of the wake-up signal and sends a wake-up signal when wake-up is required. After the network side obtains the wake-up signal, it sends a SIB1 message in the corresponding cell according to the indication information of the wake-up signal.

[0233] As shown in Figure 3, it includes:

[0234] Step 1: The idle / inactive UE obtains the wake-up signal configuration information.

[0235] Specifically, the wake-up signal configuration information includes at least one of the following contents through pre-configuration information, a system message of the resident cell, or an RRC message when previously in a connected state:

[0242] The wake-up signal for all cells of a specific RNA configured by the RRC message or RRC release message when the UE is in the connected state;

[0243] A wake-up signal for a specific cell group configured by an RRC message or an RRC release message when the UE is in a connected state.

[0244] Furthermore, the wake-up signal or a parameter related to the wake-up signal is used to indicate at least one of the following:

[0246] The number of times the SIB1 message is repeated in one sending cycle;

[0247] The number of repetitions of the SIB1 message sending cycle;

[0248] Send or stop sending SIB1 message.

[0249] Step 2: Send a wake-up signal to the target cell or base station when the preset conditions are met or based on the UE's internal implementation decision;

[0250] The preset conditions include at least one of the following:

[0251] The channel quality of the cell where the terminal resides is lower than and / or equal to a first threshold;

[0252] The signaling quality of the target cell measured by the terminal is higher than and / or equal to a second threshold;

[0253] The target cell meets the conditions for terminal cell selection or reselection;

[0254] The camped cell of the terminal enables the terminal to send a wake-up signal to a specific cell or a specific cell group or a cell in a specific RAN area or a cell in a specific area range;

[0255] The terminal has uplink data to transmit or is ready to access the network;

[0256] The terminal needs to update the SIB1 message of the wake-up cell;

[0257] The terminal receives a system message update indication related to the wake-up cell.

[0258] Step 3: After receiving the UE's wake-up signal, the gNB sends the SIB1 message.

[0259] Furthermore, the SIB1 message is sent when at least one of the following conditions is met.

[0260] The gNB senses (receives) the wake-up signal sent by the UE;

[0261] The gNB detects that the wake-up signal sent by the UE is for the current cell, the current RNA, or the current cell group.

[0262] The UE wake-up signal received by the gNB is higher than a threshold.

[0263] Furthermore, the gNB sends a SIB1 message based on the wake-up signal information, as follows:

[0264] The sending period of the SIB1 message is less than or equal to the sending period indicated by the wake-up signal or a parameter related to the wake-up signal or a predefined value;

[0265] The number of repetitions of the SIB1 message in a transmission cycle is greater than or equal to the number of repetitions of the SIB1 message in the transmission cycle indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value;

[0266] The number of repetitions of the transmission period of the SIB1 message is greater than or equal to the number of repetitions of the transmission period of the SIB1 message indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value.

[0267] The number of times the SIB1 message is sent is greater than or equal to the number of times the SIB1 message is sent indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value.

[0268] Step 4: The UE reads the SIB1 message and chooses to camp on or access the cell based on the SIB1 message.

[0269] In the above embodiment, after the gNB obtains the wake-up message of SIB1, if the SSB message has not been sent yet, the sending of the SSB message can be triggered.

[0270] The wake-up signal in the above embodiment may be one of RA scrambling code, SRS, and DMRS signals, or a combination thereof.

[0271] The time-frequency resource or transmission period of at least one of the RA scrambling code, SRS, and DMRS may be used to explicitly or implicitly indicate the UE's indication of the SIB1 message. The indication information is used to instruct the gNB to transmit a SIB1 message, transmit a SIB1 message and an SSB message, transmit a certain signal combination message, and / or information such as the resources and period for transmitting these messages.

[0272] In the embodiment of the present disclosure, a UE in an idle / inactive state can wake up surrounding cells to send SIB1 messages so that the UE can reside in or access the cell, avoiding the UE entering a connected state and then obtaining relevant information, thereby reducing the delay for the UE to access the cell.

[0273] As shown in FIG4 , an embodiment of the present disclosure further provides a signal transmission method, which is performed by a first network-side device, which may be specifically a base station. The method includes:

[0274] Step 401: Send wake-up signal configuration information to the terminal, where the wake-up signal configuration information is used to configure at least one of a wake-up signal for a specific cell, a wake-up signal for a specific frequency, a wake-up signal for a cell within a specific wireless access network notification area RNA, a wake-up signal for a specific cell group, and a wake-up signal for a cell within a specific area.

The wake-up signal is used to request the cell to send SIB1, so that after the terminal sends the wake-up signal to the target cell based on the wake-up signal configuration information, it can trigger the target cell to send SIB1 to the terminal, thereby achieving the purpose of enabling the terminal in an idle or inactive state to obtain the SIB1 of the target cell (which may be a neighboring cell).

[0276] In some embodiments, the sending the wake-up signal configuration information to the terminal includes:

[0277] The wake-up signal configuration information is acquired through at least one of pre-configuration information, a system message of a current resident cell, a radio resource control RRC message of a current resident cell, a system message of a historical resident cell, and an RRC message of a historical resident cell.

[0278] In some embodiments, the above-mentioned RRC message includes at least one of an RRC reconfiguration message and an RRC release message.

[0279] Exemplarily, the network-side device may configure a wake-up signal for a specific cell, a wake-up signal for all cells in a specific RAN, or a wake-up signal for a specific cell group through pre-configuration information;

[0280] Alternatively, the network side device can broadcast a wake-up signal for a specific cell, a specific cell group, a specific RNA, or all cells within a specific Area scope through a system message;

[0281] Alternatively, when the terminal is in the RRC connected state, the network side device can configure the wake-up signal for a specific cell, a specific cell group or all cells in a specific RNA through an RRC message.

[0282] In some embodiments, before sending the wake-up signal configuration information to the terminal, the method further includes:

The wake-up signal is used to request the cell to send SIB1, so that after the terminal sends the wake-up signal to the target cell based on the wake-up signal configuration information, it can trigger the target cell to send SIB1 to the terminal, thereby achieving the purpose of enabling the terminal in an idle or inactive state to obtain the SIB1 of the target cell (which may be a neighboring cell).

[0294] As shown in FIG5 , an embodiment of the present disclosure further provides a signal transmission method, which is performed by a second network side device, specifically a base station, and the second network side device is a neighboring base station of the first network side device. The method includes:

[0296] Step 502: Send a system information block SIB1 message to the terminal according to the wake-up signal.

[0297] Specifically, when at least one of the following conditions is met, the SIB1 message is sent to the terminal.

[0298] The second network side device determines that the wake-up signal is a wake-up signal for the current cell, the current RNA, or the current cell group;

[0299] The signal quality of the wake-up signal is higher than the preset threshold.

[0300] In the embodiment of the present disclosure, a wake-up signal is obtained; and according to the wake-up signal, a system information block SIB1 message is sent to the terminal, so that the terminal in an idle or inactive state can obtain the SIB1 of the second network side device.

[0301] In some embodiments, the wake-up signal or a parameter related to the wake-up signal is used to indicate at least one of the following:

[0303] The number of times the SIB1 message is repeated in one sending cycle;

[0307] In some embodiments, the SIB1 message sent to the terminal satisfies at least one of the following:

[0308] The sending period of the SIB1 message is less than or equal to the sending period indicated by the wake-up signal or a parameter related to the wake-up signal or a predefined value;

[0310] The number of repetitions of the transmission period of the SIB1 message is greater than or equal to the number of repetitions of the transmission period of the SIB1 message indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value;

[0311] The number of times the SIB1 message is sent is greater than or equal to the number of times the SIB1 message is sent indicated by the wake-up signal or a parameter related to the wake-up signal, or a predefined value.

[0312] In some embodiments, after obtaining the wake-up signal, the method further includes:

[0313] Send SSB.

[0314] Exemplarily, after the target cell receives the wake-up signal, if the SSB has not been sent yet, the sending of the SSB may be triggered.

[0315] In some embodiments, before obtaining the wake-up signal, the method further includes:

[0316] Sending wake-up signal configuration information through at least one of the Xn interface, the F1 interface, and the core network interface;

[0317] Alternatively, the wake-up signal configuration information configured by the neighboring cell or the core network is received through at least one of the Xn interface, the F1 interface, and the core network interface.

[0318] In the case where the above-mentioned wake-up signal configuration information is configured by the second network side device itself, the wake-up signal configuration information is sent to the neighboring cell through at least one of the Xn interface, the F1 interface and the core network interface.

[0319] The following describes the process of exchanging wake-up signal configuration information between base stations in conjunction with Example 2.

[0320] Embodiment 2: As shown in FIG6 , it includes:

[0321] Step 0: Before sending the wake-up signal configuration information to gNB2, gNB1 obtains a request message from gNB2. The request message is used to request the sending of the wake-up signal configuration information or to request the activation of the cell.

[0322] This step can be omitted.

[0323] Step 1: gNB1 sends wake-up signal configuration information to gNB2.

[0324] Furthermore, the wake-up signal configuration information may also include activation indication information of the cell SSB.

[0325] The wake-up signal configuration information is used to configure at least one of a wake-up signal for a specific cell, a wake-up signal for a specific frequency, a wake-up signal for a cell within a specific RNA, a wake-up signal for a specific cell group, and a wake-up signal for a cell within a specific Area scope.

[0326] Step 2: gNB1 obtains confirmation information from gNB2.

[0327] Step 3: gNB2 broadcasts the wake-up signal configuration information.

[0328] Furthermore, gNB2 can also broadcast the activation information of the SSB of neighboring cells.

[0329] In some embodiments, the wake-up signal includes at least one of a random access (RA) scrambling code, a sounding reference signal (SRS), an SRS positioning reference signal for positioning, and a demodulation reference signal (DMRS).

[0330] In the embodiment of the present disclosure, at least one of the following may be explicitly or implicitly indicated through the time domain resources, frequency domain resources, transmission period, etc. of at least one of RA, SRS, and DMRS:

[0334] SIB1 message is sent or stopped;

[0335] SSB message sends or stops sending;

[0336] The sending cycle of SSB messages;

[0337] The number of times the SSB message is repeated in one sending cycle;

[0338] The number of repetitions of the SSB message sending cycle.

[0339] In addition, when the first network side device is a centralized unit (CU) and the second network side device is a distributed unit (DU); or the first network side device is a DU and the second network side device is a CU, the process of exchanging wake-up signal configuration information between base stations may include:

[0340] The CU sends the wake-up signal configuration information to the DU, and the DU feeds back a confirmation message. Alternatively, the CU sends a request message for the wake-up signal configuration information to the DU, and the CU obtains the wake-up signal configuration information from the DU.

[0341] The DU obtains the wake-up signal of the UE, sends a SIB1 message on the air interface, and notifies the CU of the DU being awakened and / or relevant information of the UE that wakes up the DU.

[0342] Through the above scheme, the purpose of exchanging wake-up signal configuration information between base stations is achieved, so that after the terminal sends a wake-up signal to the target cell based on the wake-up signal configuration information, it can trigger the target cell to send SIB1 to the terminal, thereby achieving the purpose of enabling the terminal in an idle or inactive state to obtain the SIB1 of the target cell (which may be a neighboring cell).
