[0029] The embodiments of the present disclosure provide a communication method and a device thereof.

[0030] In the first aspect, an embodiment of the present disclosure proposes a communication method, which is executed by a terminal, and the method includes: determining that the terminal has sent the first information, and starting a timer; the first information is used to request the first cell to send a first synchronization signal block SSB and / or a system information block SIB1, and the timer is used to indicate the length of time the terminal monitors the first SSB and / or SIB1 sent by the first cell; based on the timer, determining whether the first information needs to be resent.

[0031] In the above embodiment, after the terminal sends the first information, the timer is started, and whether the first information needs to be resent is determined by the timer. This can solve the problem of how to perform subsequent processing after the terminal requests SSB and / or SIB1 from the SSB / SIB1-less cell through the first information in the SSB / SIB1-less cell (such as the first cell) scenario. In this way, when the terminal sends the wake-up signal but does not detect the SSB and / or SIB1 sent by the SSB / SIB1-less cell, the wake-up signal can be resent in time to request the SSB / SIB1-less cell to send SSB and / or SIB1.

[0032] In combination with some embodiments of the first aspect, in some embodiments, determining whether the first information needs to be resent based on the timer includes: monitoring the first SSB and / or SIB1 sent by the first cell during the operation of the timer, and determining that the first information does not need to be resent; or, not monitoring the first SSB and / or SIB1 sent by the first cell during the operation of the timer, and determining that the first information needs to be resent.

[0033] In the above embodiment, while the timer is running, the first SSB and / or SIB1 sent by the first cell is monitored, so as to judge whether the first information needs to be resent according to the monitoring result, thereby providing an effective basis for resending the first information.

[0034] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: when the terminal monitors the first SSB and / or SIB1 sent by the first cell during the operation of the timer, the terminal stops the timer.

[0035] In the above embodiment, if it is monitored that the first cell sends the first SSB during the operation of the timer, the timer is stopped in time to save resources, so that the terminal can use the first SSB to achieve synchronization on the first cell in time.

[0036] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: the terminal resending the first information to the first cell after the timer expires.

[0037] In the above embodiment, if the first SSB and / or SIB1 sent by the first cell is not monitored during the operation of the timer, after the timer expires, the terminal re-sends the first information to the first cell to request the first cell to send the first SSB and / or the SIB1, so that the wake-up signal can be re-sent in time to request the SSB / SIB1-less cell to send SSB and / or SIB1 when the terminal sends the wake-up signal but does not detect the SSB and / or SIB1 sent by the SSB / SIB1-less cell.

[0039] In the above embodiment, when resending the first information, the transmission power of the first information that needs to be resent can be determined, and the first information can be resent to the first cell using the transmission power.

[0042] In the above embodiment, the transmission power of the first information that needs to be resent can be determined based on the transmission power of the first information that has been generated plus the power climbing step, that is, on the basis of the wake-up failure, the transmission power of the first information is gradually increased, which can avoid the occurrence of the first cell wake-up failure due to low transmission power, so that the first cell can be awakened to the greatest extent through the first information to send SSB and / or SIB1.

[0088] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, a terminal and a second cell. The communication system may also include a first cell. The number and form of devices shown in Figure 1 are for example purposes only and do not limit the embodiments of the present disclosure. In actual applications, two or more terminals, two or more second cells, and two or more first cells may be included. The communication system 100 shown in Figure 1 includes, for example, a terminal 101, a second cell 102, and a first cell 103.

[0089] In some embodiments, the terminal 101 herein may be an entity on the user side for receiving or transmitting signals, such as a mobile phone. It may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal may be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0090] In some embodiments, the first cell 103 herein may be a Network Energy Saving cell (NES cell). In some embodiments, the terminal 101 is within the coverage of the second cell, and the first cell 103 may be one or more of the NES cells associated with the second cell 102. Exemplarily, the association of the first cell 103 with the second cell 102 may mean that information or signals (such as SIB1) of the first cell 103 may be broadcast and configured via the second cell 102.

[0091] Exemplarily, a network energy-saving cell may refer to an SSB / SIB1-less cell. The SSB / SIB1-less cell does not send one or more of SSB (Synchronization Signal Block), SIB (System Information Block) 1, other SIB, and paging. The SSB / SIB1-less cell does not send SSB, and SIB1 can be broadcast and configured through an associated second cell (such as an anchor cell, also called an anchor cell, or a normal cell, or other names, which are not specifically limited in this disclosure). At the same time, the deployment of SSB / SIB1-less cells makes network deployment more flexible, because the SSB / SIB1-less cell does not change the network coverage, it only provides data services and expands the system capacity, so the SSB / SIB1-less cell can be quickly deployed, quickly used, flexibly deployed, and enabled on demand, that is, "plug and play", which improves the flexibility and timeliness of network deployment.

[0092] In some embodiments, the first cell 103 and the second cell 102 are in a neighboring relationship. Exemplarily, the first cell 103 and the second cell 102 have overlapping coverage or adjacent coverage, that is, the first cell 103 and the second cell 102 are in a neighboring relationship.

[0093] In some embodiments, the network device associated with the second cell 102 may be an access network device. The network device associated with the first cell 103 may also be an access network device. In some embodiments, the access network device is, for example, a node or device that connects a terminal device to a wireless network. The access network device may include at least one of an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a NodeB (NB), a home nodeB (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open RAN, a cloud RAN, a base station in other communication systems, and an access node in a Wi-Fi system, but is not limited thereto.

[0094] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0095] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0096] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0097] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0098] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0099] It's important to note that with the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP (3rd Generation Partnership Project) international standards organization has begun developing 5G. The main application scenarios for 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a generalized approach difficult and requiring detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key features include high connection density, low data volumes, latency-insensitive services, low module costs, and a long service life.

[0100] Since the energy consumption of 5G base stations is four times that of LTE base stations, network energy saving is an important means for operators to reduce the cost of operating 5G systems. In some embodiments, in order to save energy in the terminal in the radio resource control RRC connected state (RRC_CONNECTED), a WUS (wake up signal) is introduced. An offset in front of the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal. During this WUS duration, a WUS signal, i.e., DCI 2-6, is sent, which is encrypted by PS-RNTI (Power Saving RNTI) to indicate whether the terminal wakes up to monitor PDCCH (Physical Downlink Control Channel) during the next UE C-DRX onduration.

[0101] In some embodiments, a paging WUS (paging wake-up signal) is introduced to save energy in RRC_IDLE / INACTIVE terminals. This WUS, also known as the PEI (paging early indication), is sent sometime before the paging occasion (PO) to indicate whether the terminal is monitoring paging schedule information at that PO. The PEI is DCI 2-7, scrambled by the PEI-RNTI (paging early indication radio network temporary identifier).

[0102] In some embodiments, a request-based wake-up signal (On demand WUS) can be used to request SSB and / or SIB1 from the first cell (such as an SSB / SIB1-less cell). The first cell can be considered to be in a sleeping state and does not send SSB. Therefore, the first cell can also be called a sleeping cell, or it can be called other names, which are not specifically limited in this disclosure. If the terminal needs to obtain the SSB of the first cell, it can use WUS to wake up the sleeping cell to send SSB and / or SIB1. In some embodiments, the first cell does not have a DRS (discovery reference signal), and in some embodiments, the first cell has a DRS.

[0103] In an SSB / SIB1-less cell scenario, a terminal may request a synchronization signal block (SSB) from the first cell via a wake-up signal (WUS). However, there is currently no effective means for subsequent processing after the terminal sends the WUS.

[0104] To this end, an embodiment of the present disclosure proposes a communication method, which can solve the problem of how to perform subsequent processing after the terminal requests SSB and / or SIB1 from the SSB / SIB1-less cell through a wake-up signal in the SSB / SIB1-less cell scenario, so that when the terminal sends the wake-up signal but does not detect the SSB and / or SIB1 sent by the SSB / SIB1-less cell, the wake-up signal can be resent in time to request the SSB / SIB1-less cell to send SSB and / or SIB1.

[0105] Figure 2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0106] Step S2101: The second cell 102 sends configuration information of the first information.

[0107] In some embodiments, the configuration information of the first information may be obtained by the terminal 101 from the second cell 102. Exemplarily, the second cell 102 sends the configuration information of the first information, and accordingly, the terminal 101 may receive the configuration information of the first information sent by the second cell 102. In some embodiments, the first information is used to request the first cell 103 to send the first SSB and / or SIB1.

[0108] In some embodiments, the terminal 101 may obtain the configuration information of the first information through dedicated RRC signaling. For example, the terminal 101 is in an RRC connected state in the second cell 102 , and the terminal 101 may obtain the configuration information of the first information through dedicated RRC signaling of the second cell 102 .

[0109] In some embodiments, the terminal 101 may obtain the configuration information of the first information through the SIB (System Information Block) of the second cell 102. Exemplarily, the terminal 101 is in the RRC_IDLE / INACTIVE state in the second cell 102, and the terminal 101 may obtain the configuration information of the first information through the SIB of the second cell 102. Exemplarily, the terminal 101 is in the RRC connected state in the second cell 102, and the terminal 101 may also obtain the configuration information of the first information through the SIB of the second cell 102.

[0110] In some embodiments, the configuration information of the first information may include at least one of the following: timer configuration; power ramp-up step size of the first information; initial transmit power of the first information, or parameters used to calculate the initial transmit power; and maximum number of transmissions of the first information. In some embodiments, the timer is used to indicate the duration for which the terminal 101 monitors the first SSB and / or SIB1 transmitted by the first cell 103. In some embodiments, the first cell 103 may be one or more network energy-saving cells associated with the second cell 102. The timer is used by the terminal 101 to determine whether the first information needs to be retransmitted. In one possible implementation, the first information may be a WUS (wake-up signal), or the first information may include the WUS (wake-up signal). The WUS is used to request the first cell 103 to transmit the first SSB and / or SIB1. That is, the terminal 101 may request the first cell 103 to transmit the first SSB via the WUS. The first SSB is used by the terminal 101 to synchronize with the first cell 103. Exemplarily, the first cell 103 sends a first SSB to the terminal 101 to facilitate the terminal 101 to search and identify the cell.

[0111] In this embodiment, the configuration information of the first information may include the configuration of the timer. In this embodiment, the configuration information of the first information may include the power climbing step of the first information, wherein the power climbing step is used to determine the transmission power of the first information that needs to be retransmitted. In this embodiment, the configuration information of the first information may include the initial transmission power of the first information, or a parameter for calculating the initial transmission power, wherein the initial transmission power can be understood as the transmission power used when the terminal 101 sends the first information for the first time. In this embodiment, the configuration information of the first information may include the maximum number of transmissions of the first information, wherein the maximum number of transmissions is used to limit the number of transmissions of the first information. It should be noted that the above embodiments are not exhaustive, but are only illustrative of some embodiments, and the above embodiments may be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0112] In some embodiments, the configuration information of the first information may be configuration information of the first information associated with the first cell 103. For example, the configuration of the timer (also referred to as timer configuration) may be configured to the terminal 101 through the configuration information of the first information associated with the first cell 103. For another example, the power ramp-up step of the first information may be configured to the terminal 101 through the configuration information of the first information associated with the first cell 103, and / or the initial transmit power of the first information or a parameter used to calculate the initial transmit power may be configured to the terminal 101 through the configuration information of the first information associated with the first cell 103. For another example, the maximum number of transmissions of the first information may be configured to the terminal 101 through the configuration information of the first information associated with the first cell 103.

[0113] In some embodiments, the configuration information of the first information may further include but is not limited to at least one of the following: a preamble index or sequence reserved for the first information; configuration information of a random access opportunity (RACH Occasion, RO) resource, where the RO resource is used to send the first information.

[0114] Step S2102 : The terminal 101 sends first information to the first cell 103 for the first time.

[0115] In some embodiments, the terminal 101 determines that it needs to request the first cell 103 to send the first SSB and / or SIB1, and then sends the first information to the first cell 103 for the first time, requesting the first cell 103 to send the first SSB and / or SIB1 through the first information. It is worth noting that the terminal 101 can request the first cell 103 to send the first SSB and / or SIB1 through the first information. In some embodiments, the first information used to request the first cell 103 to send the first SSB may be the same as or different from the first information used to request the first cell 103 to send SIB1. Exemplarily, the terminal may request the first cell 103 to send the first SSB through the first WUS, and the terminal may request the first cell 103 to send SIB1 through the second WUS, wherein the first WUS and the second WUS may be the same as or different. For example, the terminal may request the first cell 103 to send the first SSB through WUS, and the terminal may request the first cell 103 to send SIB1 through other information; or, the terminal may request the first cell 103 to send the first SSB through other information, and the terminal may request the first cell 103 to send SIB1 through WUS, and the other information may not be WUS, and this disclosure does not limit this.

[0116] In some embodiments, the terminal 101 sends the first information to the first cell 103 for the first time in a first situation, wherein the first situation may include but is not limited to any of the following: the terminal 101 is in the RRC_IDLE / INACTIVE state on the second cell 102, and based on the implementation, it is determined that the first cell 103 needs to be requested to send the first SSB and / or SIB1; the terminal 101 is in the RRC_IDLE / INACTIVE state on the second cell 102, and the RSRP measurement result of the second SSB is less than or equal to the first threshold, and the second SSB is a synchronization signal block sent by the second cell 102 to the terminal 101; the terminal 101 is in the RRC_IDLE / INACTIVE state on the second cell 102 The terminal 101 enters the RRC connected state from the NACTIVE state, and receives the indication information sent by the second cell 102, where the indication information is determined to be sent by the second cell 102 based on the RSRP measurement report of the second SSB, wherein the indication information is used to instruct the terminal 101 to send the first information; the terminal 101 is in the RRC connected state on the second cell 102, and based on the implementation, it is determined that the first cell 103 needs to be requested to send the first SSB and / or SIB1; the terminal 101 is in the RRC connected state on the second cell 102, and the RSRP measurement result of the second SSB is less than or equal to the first threshold; the terminal 101 is in the RRC connected state on the second cell 102, and receives the indication information sent by the second cell 102.

[0117] Exemplarily, the terminal 101 in the RRC_IDLE / INACTIVE state on the second cell 102 may determine based on the terminal implementation that it needs to request the first cell 103 to send the first SSB and / or SIB1, and the terminal 101 may send the first information to the first cell 103 for the first time to request the first cell 103 to send the first SSB and / or SIB1. Wherein, the terminal 101 in the RRC_IDLE / INACTIVE state on the second cell 102 may determine based on the terminal implementation that it needs to request the first cell 103 to send the first SSB, and may request the first cell 103 to send the first SSB for the first time through the first information. In some embodiments, the first SSB is used for the terminal 101 to achieve synchronization in the first cell 103. Exemplarily, the first cell 103 sends the first SSB to the terminal 101 to facilitate the terminal 101 to search and identify the cell. For example, for a terminal 101 in an RRC_IDLE / INACTIVE state on the second cell 102, the terminal 101 may determine based on the terminal implementation that it needs to request the first cell 103 to send SIB1, and may request the first cell 103 to send SIB1 for the first time through the first information. In some embodiments, SIB1 may carry information related to whether the terminal 101 is allowed to access the cell (such as parameters for the terminal 101 to access the cell), and may also carry scheduling information of other SIB types (such as but not limited to one or more of SIB5, SIB6, SIB7, etc.). The SIB1 may also provide radio resource configuration information shared by all terminals and prohibition information required for unified access control, or may also carry other information. This disclosure does not limit this and will not elaborate on it.

[0118] Exemplarily, the terminal 101 in the RRC_IDLE / INACTIVE state on the second cell 102 measures the RSRP of the second SSB sent by the second cell 102. When the RSRP measurement result of the measured second SSB (such as the RSRP value of the second SSB) is less than or equal to the first threshold, the terminal 101 sends first information to the first cell 103 for the first time to request the first cell 103 to send the first SSB and / or SIB1. Exemplarily, the terminal 101 in the RRC_IDLE / INACTIVE state on the second cell 102 can obtain measurement configuration information from the SIB of the second cell 102, and measure the RSRP of the second SSB sent by the second cell 102 based on the measurement configuration information. The above-mentioned measurement configuration information may include but is not limited to at least one of the following: content information of the measurement report, information related to the measured reference signal resource, and association relationship information between the reference signal resource and the measurement report. In some embodiments, the above-mentioned measurement configuration information can be used by the terminal 101 to measure the RSRP of the second SSB sent by the second cell 102. Exemplarily, the first threshold may be preconfigured, or the first threshold may be obtained by the terminal 101 from the measurement configuration information of the second cell 102. Specifically, when the terminal 101 is in the RRC_IDLE / INACTIVE state on the second cell 102, and the terminal 101 determines that the RSRP measurement result of the measured second SSB (such as the RSRP value of the second SSB) is less than or equal to the first threshold, the terminal 101 may request the first cell 103 to send the first SSB for the first time through the first information. In some embodiments, the first SSB is used by the terminal 101 to achieve synchronization in the first cell 103. Exemplarily, the first cell 103 sends the first SSB to the terminal 101 to facilitate cell search and identification by the terminal 101. Exemplarily, when the terminal 101 is in the RRC_IDLE / INACTIVE state on the second cell 102, and the terminal 101 determines that the RSRP measurement result of the measured second SSB (such as the RSRP value of the second SSB) is less than or equal to the first threshold, the terminal 101 may request the first cell 103 to send SIB1 for the first time through the first information. In some embodiments, SIB1 can carry information related to whether terminal 101 is allowed to access the cell (such as parameters for terminal 101 to access the cell), and can also carry scheduling information of other SIB types (such as one or more of but not limited to SIB5, SIB6, SIB7, etc.). The SIB1 can also provide radio resource configuration information shared by all terminals and prohibition information required for unified access control, or can also carry other information. This disclosure does not limit this and will not elaborate on it.

[0119] Exemplarily, the terminal 101 enters the RRC connected state from the RRC_IDLE / INACTIVE state on the second cell 102, and the terminal 101 measures the RSRP of the second SSB sent by the second cell 102. Exemplarily, the measurement result of the RSRP of the second SSB is less than or equal to the first threshold, and the RSRP measurement report of the second SSB is reported to the second cell 102. Exemplarily, the RSRP measurement report of the second SSB is periodically reported to the second cell 102. The second cell 102 determines based on the network implementation that the terminal 101 needs to wake up the first cell through the first information to send SSB and / or SIB1, then the second cell 102 sends an indication message to the terminal 101. After receiving the indication message, the terminal 101 sends the first information to the first cell 103 for the first time to request the first cell 103 to send the first SSB and / or SIB1. The implementation method of measuring the RSRP of the second SSB sent by the second cell 102 and the related description of the first threshold can be found in the above description and will not be repeated here. In this case, terminal 101 enters an RRC connected state from an RRC_IDLE / INACTIVE state on second cell 102. Terminal 101 reports an RSRP measurement report of a measured second SSB to second cell 102. Second cell 102 instructs the terminal to send first information to first cell 103 via indication information. Terminal 101 can then request first cell 103 to send a first SSB for the first time via the first information. In some embodiments, the first SSB is used for terminal 101 to synchronize with first cell 103. Exemplarily, first cell 103 sends the first SSB to terminal 101 to facilitate cell search and identification for terminal 101. Exemplarily, terminal 101 enters an RRC connected state from an RRC_IDLE / INACTIVE state on second cell 102. Terminal 101 reports an RSRP measurement report of a measured second SSB to second cell 102. Second cell 102 instructs the terminal to send first information to first cell 103 via indication information. Terminal 101 can then request first cell 103 to send SIB1 for the first time via the first information. In some embodiments, SIB1 can carry scheduling information of other SIB types (such as but not limited to one or more of SIB5, SIB6, SIB7, etc.). The SIB1 can also provide radio resource configuration information shared by all terminals and prohibition information required for unified access control, or can also carry other information. This disclosure does not limit this and will not elaborate on it.

[0120] Exemplarily, a terminal 101 in an RRC connected state on a second cell 102 may determine, based on terminal implementation, that it is necessary to request the first cell 103 to transmit a first SSB and / or SIB1. Terminal 101, in an RRC connected state on the second cell 102, may determine, based on terminal implementation, that it is necessary to request the first cell 103 to transmit a first SSB. Terminal 101 may request, through the first message, for the first time to transmit the first SSB. In some embodiments, the first SSB is used for terminal 101 to synchronize with the first cell 103. Exemplarily, the first cell 103 transmits the first SSB to terminal 101 to facilitate cell search and identification by terminal 101. Exemplarily, a terminal 101 in an RRC connected state on the second cell 102 may determine, based on terminal implementation, that it is necessary to request the first cell 103 to transmit SIB1. Terminal 101 may request, through the first message, for the first time to transmit SIB1. In some embodiments, SIB1 can carry scheduling information of other SIB types (such as but not limited to one or more of SIB5, SIB6, SIB7, etc.). The SIB1 can also provide radio resource configuration information shared by all terminals and prohibition information required for unified access control, or can also carry other information. This disclosure does not limit this and will not elaborate on it.

[0121] Exemplarily, terminal 101 is in an RRC connected state on second cell 102, and terminal 101 measures the RSRP of a second SSB sent by second cell 102. When the RSRP measurement result of the measured second SSB (such as the RSRP value of the second SSB) is less than or equal to a first threshold, terminal 101 sends first information to first cell 103 for the first time to request first cell 103 to send the first SSB and / or SIB1. Exemplarily, terminal 101 is in an RRC connected state on second cell 102, and can obtain measurement configuration information from the SIB and / or dedicated RRC signaling of second cell 102, and measure the RSRP of the second SSB sent by second cell 102 based on the measurement configuration information. The measurement configuration information may include, but is not limited to, at least one of the following: content information of the measurement report, information related to the measured reference signal resource, and association information between the reference signal resource and the measurement report. In some embodiments, the measurement configuration information may be used by terminal 101 to measure the RSRP of the second SSB sent by second cell 102. Exemplarily, the first threshold may be preconfigured, or the first threshold may be obtained by the terminal 101 from measurement configuration information of the second cell 102 .

[0122] Exemplarily, the terminal 101 is in an RRC connected state on the second cell 102, and the terminal 101 measures the RSRP of the second SSB sent by the second cell 102. Exemplarily, the measurement result of the RSRP of the second SSB is less than or equal to the first threshold, and the RSRP measurement report of the second SSB is reported to the second cell 102. Exemplarily, the RSRP measurement report of the second SSB is periodically reported to the second cell 102. The second cell 102 determines based on the network implementation that the terminal 101 needs to wake up the first cell through the first information to send SSB and / or SIB1, then the second cell 102 sends an indication message to the terminal 101. After receiving the indication message, the terminal 101 sends the first information to the first cell 103 for the first time to request the first cell 103 to send the first SSB and / or SIB1. The implementation method of measuring the RSRP of the second SSB sent by the second cell 102 and the related description of the first threshold can be found in the above description and will not be repeated here.

[0123] It should be noted that the timing when the terminal sends the first information to the first cell 103 for the first time given above is only an example shown to facilitate the understanding of those skilled in the art, and cannot be used as a specific limitation of the present disclosure. That is to say, other methods can also be used to determine the need to request the first cell 103 to send the first SSB and / or SIB1, and the terminal 101 sends the first information to the first cell 103 for the first time. That is, as long as it is determined that the first cell 103 needs to be requested to send the first SSB and / or SIB1, and the terminal 101 sends the first information to the first cell 103 for the first time, the solution of the present disclosure can be used for subsequent processing after the first information is sent for the first time.

[0124] In some embodiments, the terminal 101 may use the initial transmission power of the first information to send the first information for the first time to the first cell 103. Exemplarily, if the terminal 101 determines that it needs to request the first cell 103 to send the first SSB and / or SIB1, the terminal 101 may use the initial transmission power of the first information to send the first information to the first cell 103 for the first time to request the first cell 103 to send the first SSB and / or SIB1.

[0125] In some embodiments, the terminal 101 may obtain the configuration information of the first cell 103 through the SIB of the second cell 102. In some embodiments, the terminal 101 may obtain the configuration information of the first cell 103 through dedicated RRC signaling of the second cell 102. Exemplarily, the configuration information of the first cell 103 includes at least one of the following: an identifier and / or frequency of the first cell 103; RACH (Random Access Channel)-related configuration information of the first cell 103; configuration information of the first information associated with the first cell 103; and information in the SIB1 of the first cell 103. For a description of the configuration information of the first information associated with the first cell 103, refer to the description of the configuration information of the first information in step S2101 above, which will not be repeated here.

[0126] In some embodiments, the terminal 101 may send the first information to the first cell 103 based on the configuration information of the first cell 103 and / or the configuration information of the first information associated with the first cell 103 to request the first cell 103 to send the first SSB and / or SIB1.

[0127] It should be noted that the first SSB in this article can be understood as the synchronization signal block sent by the first cell 103, and the second SSB can be understood as the synchronization signal block sent by the second cell 102.

[0128] It should be noted that, in some embodiments, the second cell 102 may be associated with one or more first cells, and the configuration information of the first information associated with the one or more first cells may be the same or different. Exemplarily, the one or more first cells may be associated with different configuration information of the first information, or exemplary, the one or more first cells may be associated with the same configuration information of the first information. For example, the second cell 102 may be associated with one or more first cells, and the terminal 101 may send the first information to at least some of the one or more first cells 103 associated with the second cell 102. Sending the first information to at least some of the one or more first cells 103 associated with the second cell 102 may mean sending the first information to one or more of the one or more first cells 103 associated with the second cell 102, or sending the first information to all of the first cells 103 associated with the second cell 102. When there is more than one first cell 103, the first information is sent using the configuration information of the first information of each of the more than one first cells 103. For example, first cell 1, first cell 2, and first cell 3 are respectively network energy-saving cells associated with second cell 102. The terminal can use the configuration information of the first information associated with first cell 1 to send the first information to first cell 1, and use the configuration information of the first information associated with first cell 2 to send the first information to first cell 2. The configuration information of the first information associated with first cell 1, first cell 2, and first cell 3 can be the same or different. Taking the example of the first information associated with at least some of the first cells being the same, terminal 101 can send the first information to at least some of the first cells based on the configuration information of at least some of the first cells and / or the configuration information of the same first information associated with at least some of the first cells. For example, taking the second cell 102 as being associated with first cell a and first cell b, the configuration information of the first information associated with first cell a and first cell b can be the same. Terminal 101 can send the first information to first cell a and first cell b, respectively, based on the configuration information of first cell a and first cell b and / or the configuration information of the same first information associated with first cell a and first cell b.

[0129] Taking the configuration information of different first information associated with at least part of the first cells as an example, the terminal 101 can send the first information to the at least part of the first cells based on the configuration information of the at least part of the first cells and / or the configuration information of the first information associated with the at least part of the first cells. For example, taking the second cell 102 as associating the first cell a and the first cell b, the configuration information of the first information associated with the first cell a is different from the configuration information of the first information associated with the first cell b, such as the first information associated with the first cell a is called first information 1, and the first information associated with the first cell b is 2. The terminal 101 can send the first information 1 to the first cell a based on the configuration information of the first cell a and / or the configuration information of the first information 1 associated with the first cell a, and send the first information 2 to the first cell b based on the configuration information of the first cell b and / or the configuration information of the first information 2 associated with the first cell b.

[0130] Optionally, in some embodiments, the second cell 102 can be associated with one or more first cells 103, and the terminal can determine based on terminal implementation whether to send first information to a first cell associated with the second cell 102, or to send first information to multiple first cells associated with the second cell 102, or to send first information to all first cells associated with the second cell 102.

[0131] Step S2103: Terminal 101 determines that Terminal 101 has finished sending the first information and starts a timer.

[0132] In some embodiments, after the terminal 101 sends the first information, a timer is started. The timer can be used to indicate the duration for which the terminal 101 monitors the first SSB and / or SIB1 transmitted by the first cell 103. While the timer is running, the terminal 101 can monitor the first SSB and / or SIB1 transmitted by the first cell 103. The timer can be configured for the terminal 101 using the configuration information of the first information of the second cell 102. The optional implementation method thereof can be found in the description of step S2101 above and will not be repeated here.

[0133] Step S2104: The terminal 101 monitors the first SSB and / or SIB1 sent by the first cell 103 during the timer running, and determines that there is no need to resend the first information.

[0134] Exemplarily, during the timer running, the terminal 101 may monitor the first SSB and / or SIB1 sent by the first cell 103. If the terminal 101 monitors the first SSB and / or SIB1 sent by the first cell 103 during the timer running, it may be determined that there is no need to resend the first information, that is, there is no need to resend the first information to the first cell 103 to request the first cell to send the first SSB and / or SIB1. In some embodiments, the terms "monitor", "detect", "receive", "discover", etc. may be used interchangeably.

[0135] Step S2105: When the terminal 101 monitors the first SSB and / or SIB1 sent by the first cell 103 during the timer running, the terminal 101 stops the timer.

[0136] Exemplarily, during the timer running, if the terminal 101 monitors the first SSB and / or SIB1 sent by the first cell 103, the terminal 101 stops the timer. For example, if the terminal 101 monitors the first SSB and / or SIB1 sent by the first cell 103 during the timer running, it can be considered that the first cell 103 has been successfully awakened to send the first SSB and / or SIB1, so that the terminal 101 can achieve synchronization in the first cell 103 using the first SSB.

[0137] Step S2106: The terminal 101 does not monitor the first SSB and / or SIB1 sent by the first cell 103 during the timer running period, and determines that the first information needs to be resent.

[0138] Exemplarily, during the timer running, the terminal 101 does not monitor the first SSB and / or SIB1 sent by the first cell 103. It can be considered that the first information (such as WUS) request has failed, and it can be determined that the first information needs to be resent to request the first cell to send the first SSB and / or SIB1.

[0139] Step S2107: After the timer expires, the terminal 101 resends the first information to the first cell 103.

[0140] Exemplarily, during the operation of the timer, the terminal 101 may monitor the first SSB and / or SIB1 sent by the first cell 103. If the terminal 101 does not monitor the first SSB and / or SIB1 sent by the first cell 103 during the operation of the timer, after the timer expires, the terminal 101 may resend the first information to the first cell 103 to request the first cell to send the first SSB and / or SIB1.

[0141] In some embodiments, the terminal 101 may determine the current number of times the first information has been sent; the terminal 101 determines that the current number of times the first information has been sent is less than or equal to the maximum number of times it has been sent, and resends the first information to the first cell 103. Exemplarily, after a timer expires, the terminal 101 needs to determine the current number of times the first information has been sent. If the current number of times the first information has been sent is less than or equal to the maximum number of times the first information has been sent, the terminal 101 may resend the first information to the first cell 103. Exemplarily, the terminal 101 may resend the first information to the first cell 103 based on the configuration information of the first cell 103 and / or the configuration information of the first information associated with the first cell 103, so as to request the first cell 103 to send the first SSB and / or SIB1.

[0142] It should be noted that, in some embodiments, the above-mentioned maximum number of transmissions (such as the maximum number of transmissions of the first information) can be configured to the terminal 101 through the configuration information of the first information of the second cell 102. The optional implementation method can be found in the relevant description of the above-mentioned step S2101, which will not be repeated here.

[0143] In some embodiments, the possible implementation of the above-mentioned resending of the first information to the first cell 103 may include: the terminal 101 determines the transmit power of the first information that needs to be resent, and uses the transmit power to resend the first information to the first cell 103. Exemplarily, after a timer expires, the terminal 101 determines the transmit power of the first information that needs to be resent, and resends the first information to the first cell 103 using the transmit power to request the first cell 103 to send the first SSB and / or SIB1. Exemplarily, after a timer expires, the terminal 101 determines that the current number of times the first information has been sent is less than or equal to the maximum number of times the first information has been sent, and the terminal 101 determines the transmit power of the first information that needs to be resent, and resends the first information to the first cell 103 using the transmit power to request the first cell 103 to send the first SSB and / or SIB1.

[0144] In some embodiments, a possible implementation of the above-mentioned determination of the transmit power of the first information that needs to be retransmitted may include: the terminal 101 determines the transmit power of the first information that needs to be retransmitted based on the transmit power of the first information that has been transmitted and the power ramping step size. In some embodiments, the terminal 101 increases the transmit power of the first information that has been transmitted by the above-mentioned power ramping step size to determine the transmit power of the first information that needs to be retransmitted. Exemplarily, the power ramping step size of the first information may be the power ramping step size of the wake-up signal (WUS power ramping step).

[0145] Exemplarily, taking the first information that has been sent as the first information that has been sent for the first time as an example, the terminal 101 uses the initial transmission power of the first information to send the first information to the first cell 103 for the first time, and determines that the first information request fails (such as the timer times out and the first SSB and / or SIB1 sent by the first cell 103 is not monitored), the terminal 101 adds a power climbing step on the basis of the transmission power of the first information sent for the first time (that is, the initial transmission power of the first information), and obtains the transmission power of the first information that needs to be resent. For example, the initial transmission power of the first information is A, and the power climbing step is a, then the terminal 101 adds a power climbing step on the basis of the transmission power of the first information sent for the first time (that is, the initial transmission power of the first information), and obtains the transmission power of the first information that needs to be resent as A+a.

[0146] Exemplarily, based on the above example, taking the first information that has been sent as the second time after the first time as an example, the terminal 101 determines that the request for the second information sent for the second time has failed (for example, after the second information is sent for the second time, the timer times out and the first SSB and / or SIB1 sent by the first cell 103 is not monitored, the terminal 101 adds a power climbing step a to the transmission power A+a of the first information sent for the second time, and obtains the transmission power of the first information that needs to be resent as A+2a, that is, A+2a is the transmission power of the first information that needs to be sent for the third time, and so on. Each time the first information is resent, the transmission power of the resent first information increases by one power climbing step compared with the power of the last time the first information was sent.

[0147] Step S2108: The terminal 101 determines that the current number of times the first message has been sent is greater than or equal to the maximum number of times it has been sent, and sends a notification message.

[0148] In some embodiments, the terminal 101 determines that the first information (such as WUS) request fails (such as after sending the first information, the timer times out and the first SSB and / or SIB1 sent by the first cell 103 is not monitored), and determines whether the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent. If the terminal 101 determines that the current number of times the first information has been sent is less than or equal to the maximum number of times it has been sent, it can resend the first information to the first cell 103. If the terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, it can notify the upper layer (such as the RRC layer of the terminal 101) and / or the second cell 102. It should be noted that in some embodiments, the above-mentioned maximum number of times of sending (such as the maximum number of times of sending the first information) can be configured to the terminal 101 through the configuration information of the first information of the second cell 102. Its optional implementation method can refer to the relevant description of the above-mentioned step S2101, which will not be repeated here.

[0149] In some embodiments, the terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, and sends first notification information to the second cell 102, wherein the terminal 101 is in an RRC connected state on the second cell 102. Exemplarily, the terminal 101 in the RRC connected state on the second cell 102 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent. The terminal 101 may send first notification information to the second cell 102, notifying the second cell 102 through the first notification information that the current number of times the first information has been sent has reached the maximum number of times it has been sent. Based on the first notification information, the second cell 102 may determine that the number of times the terminal 101 has sent the first information has reached the maximum number of times it has been sent.

[0150] In some embodiments, terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, and terminal 101 enters the RRC connected state from the RRC_IDLE / INACTIVE state on the second cell 102, and sends first notification information to the second cell 102. Exemplarily, terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, and terminal 101 in the RRC_IDLE / INACTIVE state enters the connected state through the second cell 102, and then sends first notification information to the second cell 102, notifying the second cell 102 through the first notification information that the current number of times the first information has been sent has reached the maximum number of times it has been sent. Based on the first notification information, second cell 102 can determine that the number of times terminal 101 has sent the first information has reached the maximum number of times it has been sent. Exemplarily, terminal 101 in the RRC_IDLE state initiates an RRC connection establishment procedure to the second cell 102 to enter the RRC connected state, and terminal 101 in the RRC_INACTIVE state initiates an RRC connection recovery procedure to the second cell 102 to enter the RRC connected state.

[0151] In some embodiments, the terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, and sends second notification information to the RRC layer of the terminal 101. Exemplarily, the terminal 101 determines that the current number of times the first information has been sent is greater than or equal to the maximum number of times it has been sent, and can notify a higher layer (such as the RRC layer). For example, the terminal 101 sends the second notification information to the RRC layer of the terminal 101, notifying through the second notification information that the current number of times the first information has been sent has reached the maximum number of times it has been sent. Based on the second notification information, the RRC layer can determine that the number of times the terminal 101 has sent the first information has reached the maximum number of times it has been sent.

[0152] It should be noted that the first notification information in this article is the notification information sent by the terminal 101 to the second cell 102, and the second notification information is the notification information sent by the terminal 101 to the upper layer. The above-mentioned first notification information can be used for subsequent processing by the second cell, such as waking up the first cell by other means to facilitate communication between the terminal and the first cell, and the second notification information can be used for subsequent processing by the upper layer, such as waking up the first cell by other means to facilitate communication between the terminal and the first cell.

[0153] It is worth noting that in some embodiments, the second cell 102 can be associated with one or more first cells, and the scheme involved in the embodiment of the present disclosure is executed separately for each first cell. Exemplarily, the second cell 102 can be associated with the first cell 1 and the first cell 2, and the terminal 101 can send the first information to the first cell 1 based on the configuration information of the first cell 1 and / or the configuration information of the first information associated with the first cell 1. The terminal 101 determines that the first information associated with the first cell 1 has been sent, starts the timer, and stops the timer if the SSB and / or SIB1 sent by the first cell 1 is monitored during the operation of the timer; if the SSB and / or SIB1 sent by the first cell 1 is not monitored during the operation of the timer, the first information associated with the first cell 1 is resent to the first cell 1 after the timer expires. The terminal 101 determines that the current number of times the first information associated with the first cell 1 has been sent is greater than or equal to the maximum number of times it has been sent, and notifies the upper layer and / or the second cell 102. The second cell 102 may be associated with the first cell 2. The terminal 101 may send the first information to the first cell 2 based on the configuration information of the first cell 2 and / or the configuration information of the first information associated with the first cell 2. The terminal 101 determines that the first information associated with the first cell 2 has been sent, starts a timer, and stops the timer if it monitors the SSB and / or SIB1 sent by the first cell 2 during the timer running. If the SSB and / or SIB1 sent by the first cell 2 is not monitored during the timer running, the terminal 101 resends the first information associated with the first cell 2 to the first cell 2 after the timer expires. The terminal 101 determines that the current number of times the first information associated with the first cell 2 has been sent is greater than or equal to the maximum number of times, and notifies the upper layer and / or the second cell 102.

[0256] In some embodiments, the above method may include the method described in the above terminal side, second cell side, etc. embodiments, which will not be repeated here.

[0257] The present disclosure provides a communication method that solves the problem in an SSB / SIB1-less cell scenario where a terminal can request an SSB and / or SIB1 from an SSB / SIB1-less cell using a first message (e.g., a WUS), but the terminal's specific behavior after sending the WUS is unclear. The present disclosure is described in detail below with reference to examples in conjunction with the embodiments.

[0258] The present disclosure defines a timer, during which the terminal monitors the SSB and / or SIB1 sent by the first cell.

[0259] In some embodiments, after the terminal sends the WUS, the timer is started. During the timer operation, the terminal monitors the SSB and / or SIB1 sent by the first cell. When the terminal monitors (such as detecting / receiving) the SSB and / or SIB1 sent by the first cell, the terminal stops the timer. When the timer times out, the terminal resends the first information (such as the WUS) and requests the first cell to send the SSB and / or SIB1. During the timer operation, if the SSB and / or SIB1 sent by the first cell is not monitored, the terminal considers that the first information request has failed.

[0260] In some embodiments, the terminal obtains the timer configuration through the SIB or dedicated RRC signaling of the second cell. A terminal in the RRC_IDLE / INACTIVE state obtains the timer configuration through the SIB of the second cell. A terminal in the RRC_CONNECTED state obtains the timer configuration through dedicated RRC signaling of the second cell.

[0261] In some embodiments, the terminal obtains the configuration of the timer through the SIB of the second cell. A terminal in the RRC_IDLE / INACTIVE / CONNECTED state obtains the configuration of the timer through the SIB of the second cell.

[0263] The present disclosure defines a power ramp-up step size of the first information and / or an initial transmission power of the first information.

[0264] In some embodiments, an initial transmit power of the first information is defined, where the initial transmit power is the power used by the terminal when it first transmits the first information (also called the initial transmission) to request the first cell to transmit the SSB and / or SIB1. If the terminal determines that the first information request has failed (e.g., a timer expires and no SSB and / or SIB1 is detected or received), the terminal retransmits the first information, and the retransmitted first information has a power increase by a value, such as WUSpowerrampingstep (power ramping step), compared to the initial transmit power. Similarly, each retransmission of the first information has a power increase by this value compared to the power of the last transmission of the first information.

[0265] In some embodiments, the terminal obtains the power climbing step size of the first information and / or the initial transmit power of the first information through the SIB of the second cell or dedicated RRC signaling. A terminal in the RRC_IDLE / INACTIVE state obtains the power climbing step size of the first information and / or the initial transmit power of the first information through the SIB of the second cell. A terminal in the RRC_CONNECTED state obtains the power climbing step size of the first information and / or the initial transmit power of the first information through the dedicated RRC signaling of the second cell.

[0266] In some embodiments, the terminal obtains the power ramp-up step size of the first information and / or the initial transmit power of the first information through the SIB of the second cell. A terminal in the RRC_IDLE / INACTIVE / CONNECTED state obtains the power ramp-up step size of the first information and / or the initial transmit power of the first information through the SIB of the second cell.

[0267] This disclosure defines the maximum number of times the first information can be sent.

[0268] In some embodiments, a maximum number of times the first information is sent is defined, and when the number of times the first information is sent reaches the maximum number of times, the upper layer is notified.

[0269] In some embodiments, the terminal obtains the maximum number of transmissions of the first information through the SIB or dedicated RRC signaling of the second cell. A terminal in the RRC_IDLE / INACTIVE state obtains the maximum number of transmissions of the first information through the SIB of the second cell. A terminal in the RRC_CONNECTED state obtains the maximum number of transmissions of the first information through dedicated RRC signaling of the second cell.

[0270] In some embodiments, the terminal obtains the maximum number of transmission times of the first information through the SIB of the second cell. The terminal in the RRC_IDLE / INACTIVE / CONNECTED state obtains the maximum number of transmission times of the first information through the SIB of the second cell.

[0271] In some embodiments, the terminal determines that the number of times the first information is sent reaches the maximum number of times, and the terminal in the RRC connection state notifies the second cell.

[0272] In some embodiments, the terminal determines that the number of times the first information is sent reaches the maximum number of times, the terminal in the RRC_IDLE / INACTIVE state enters the connected state through the second cell, and then notifies the second cell.
