[0156] In some embodiments, data, information, etc. may be obtained with the user's consent.

[0157] 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, a first cell, and a second cell. The number and configuration 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 first cells, and two or more second cells may be included. The communication system 100 shown in Figure 1 includes, for example, a terminal 101, a first cell 102, and a second cell 103.

[0158] 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.

[0159] In some embodiments, the second cell 103 herein may be a Network Energy Saving cell (NES cell). In some embodiments, the second cell 103 may be one or more of the NES cells associated with the first cell 102. Exemplarily, the association of the second cell 103 with the first cell 102 may mean that information or signals (such as SIB1) of the second cell 103 may be broadcast and configured via the first cell 102.

[0160] 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 first 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.

[0161] In some embodiments, the second cell 103 is in a neighboring relationship with the first cell 102. Exemplarily, the second cell 103 and the first cell 102 have overlapping coverage or adjacent coverage, that is, the second cell 103 and the first cell 102 are in a neighboring relationship.

[0162] In some embodiments, the network device associated with the first cell 102 may be an access network device. The network device associated with the second 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.

[0163] 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 the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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).

[0168] 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.

[0169] 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 RRC connected state (RRC_CONNECTED) terminal, 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, the WUS signal, i.e., DCI 2-6, is sent and scrambled 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.

[0170] In some embodiments, a paging wake-up signal (WUS) is introduced to save energy for terminals in RRC_IDLE / INACTIVE states. This WUS, also known as the Paging Early Indication (PEI), is sent sometime before a paging occasion (PO) to indicate whether the terminal is monitoring for paging schedule information at that PO. The PEI is DCI 2-7, scrambled using the PEI-RNTI (Paging Early Indication Radio Network Temporary Identifier).

[0171] In some embodiments, a request-based wake-up signal (On demand WUS) can be used to request an SSB from a second cell (such as an SSB / SIB1-less cell). The second cell can usually be considered to be in a sleeping state and does not send an SSB, so the second cell can also be called a sleeping cell, or can be called other names, which are not specifically limited in this disclosure. If the terminal needs to obtain the SSB of the second cell, it can use WUS to wake up the sleeping cell to send SSB and / or SIB1. In some embodiments, the second cell does not have a DRS (discovery reference signal), and in some embodiments, the second cell has a DRS.

[0172] In the SSB / SIB1-less cell scenario, the terminal is in the coverage of the first cell (such as the anchor cell / normal cell, or other names, which are not specifically limited in this disclosure), and the network energy-saving cell without DRS is an invisible cell for the terminal. However, there is currently a lack of effective means for determining when a terminal in an RRC (Radio Resource Control) connected state on the first cell communicates with the network energy-saving cell.

[0173] To this end, an embodiment of the present disclosure proposes a communication method, which enables a terminal in an RRC connected state to request a second cell to send SSB and / or SIB1 through WUS, thereby facilitating the terminal to subsequently communicate with the second cell.

[0174] Figure 2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, 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.

[0175] Step S2101, the first cell 102 sends the first SSB to the terminal 101.

[0176] In some embodiments, the terminal 101 is in an RRC connected state on the first cell 102 .

[0177] In some embodiments, the above-mentioned first SSB is sent by the first cell 102 to the terminal 101, and accordingly, the terminal 101 receives the first SSB sent by the first cell 102.

[0178] Step S2102 : The first cell 102 sends measurement configuration information to the terminal 101 .

[0179] In some embodiments, the measurement configuration information is sent by the first cell 102 to the terminal 101 . Accordingly, the terminal 101 receives the measurement configuration information sent by the first cell 102 .

[0180] In some embodiments, 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 information on an association 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 first SSB sent by first cell 102.

[0181] In some embodiments, the first cell 102 may send the measurement configuration information to the terminal 101 through dedicated RRC signaling. In some embodiments, the first cell 102 may send the measurement configuration information to the terminal 101 through the SIB. Exemplarily, the terminal 101 in the RRC connected state on the first cell 102 may obtain the measurement configuration information from the SIB or dedicated RRC signaling of the first cell 102.

[0182] In step S2103, the terminal 101 measures the RSRP of the first SSB based on the measurement configuration information to obtain the RSRP measurement result of the first SSB.

[0183] Exemplarily, the terminal 101 may measure the RSRP value of the first SSB sent by the first cell 102 based on the measurement configuration information sent by the first cell 102 to obtain the RSRP measurement result of the first SSB.

[0184] Step S2104: Terminal 101 determines that the RSRP measurement result of the first SSB is less than or equal to the first threshold.

[0185] Exemplarily, the terminal 101 compares the RSRP measurement result of the first SSB (i.e., the measured RSRP value of the first SSB) with the first threshold. For example, the terminal can determine whether the measured RSRP value of the first SSB is less than or equal to the first threshold. If the measured RSRP value of the first SSB is less than or equal to the first threshold, it can be considered that the RSRP measurement result of the first SSB is less than or equal to the first threshold.

[0186] In some embodiments, the first threshold may be preconfigured. Alternatively, in some embodiments, the first threshold may be obtained by the terminal 101 from the measurement configuration information of the first cell 102. Exemplarily, the measurement configuration information sent by the first cell 102 to the terminal 101 includes the first threshold. The first threshold may be used by the terminal 101 to determine whether to report the RSRP measurement report of the first SSB based on the RSRP measurement result of the first SSB. Exemplarily, the terminal 101 may obtain the first threshold from the measurement configuration information, so that the terminal 101 can determine the signal quality of the SSB of the first cell based on the first threshold.

[0187] Step S2105: Terminal 101 determines to report the RSRP measurement report of the first SSB.

[0188] Exemplarily, the terminal 101 determines that the RSRP measurement result of the first SSB is less than or equal to the first threshold, then determines that it is necessary to report the RSRP measurement report of the first SSB to the first cell 102, so that the first cell 102 determines whether to send indication information to the terminal 101 based on the RSRP measurement report of the first SSB to instruct the terminal 101 to send a wake-up signal (WUS), that is, the first cell 102 triggers the terminal 101 to send a wake-up signal based on the RSRP measurement report of the first SSB to request the second cell 103 to send a second SSB and / or SIB1. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the first SSB to the first cell 102, so that the first cell 102 determines whether to send indication information to the terminal 101 based on the RSRP measurement report of the first SSB to instruct the terminal 101 to send a wake-up signal.

[0189] Step S2106, the terminal 101 sends the RSRP measurement report of the first SSB to the first cell 102.

[0190] In some embodiments, the RSRP measurement report of the first SSB may be used by the first cell 102 to determine whether to send indication information, where the indication information is used to instruct the terminal 101 to send a wake-up signal, where the wake-up signal is used to request the second cell 103 to send the second SSB and / or SIB1. Exemplarily, the RSRP measurement report of the first SSB may be used by the first cell 102 to determine whether it is necessary to trigger the terminal 101 to send a wake-up signal to request the second cell 103 to send the second SSB and / or SIB1.

[0191] In some embodiments, when the RSRP measurement result of the first SSB is less than or equal to the first threshold, the terminal 101 reports the RSRP measurement report of the first SSB to the first cell 102. Accordingly, the first cell 102 may receive the RSRP measurement report of the first SSB sent by the terminal 101. In some embodiments, the terminal 101 may periodically send the RSRP measurement report of the first SSB to the first cell 102. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the first SSB to the first cell 102, so that the first cell 102 determines whether to send indication information to the terminal 101 based on the RSRP measurement report of the first SSB to instruct the terminal 101 to send a wake-up signal.

[0192] It should be noted that, in some embodiments, steps S2104 and S2105 are optional. That is, after the terminal 101 obtains the RSRP measurement result of the first SSB, it can send the RSRP measurement report of the first SSB to the first cell 102. Alternatively, after the terminal 101 obtains the RSRP measurement result of the first SSB and determines that the RSRP measurement result of the first SSB is less than or equal to the first threshold, the RSRP measurement report of the first SSB is sent to the first cell 102.

[0193] Step S2107: The first cell 102 determines that indication information needs to be sent based on the RSRP measurement report of the first SSB.

[0194] Exemplarily, the first cell 102 may determine whether the terminal 101 needs to wake up the second cell through WUS to send the second SSB and / or SIB1 based on the RSRP measurement report of the first SSB reported by the terminal 101. For example, the first cell 102 determines that the RSRP of the first SSB is less than or equal to the first threshold based on the RSRP measurement report of the first SSB reported by the terminal 101, and may determine that the terminal 101 needs to wake up the second cell 103 through a wake-up signal. That is, the first cell 102 may determine that it is necessary to send indication information to the terminal 101 to instruct the terminal 101 to trigger WUS to request the second cell 103 to send the second SSB and / or SIB1. Exemplarily, the first cell 102 determines that it is necessary to send indication information to the terminal 101 based on network implementation to instruct the terminal 101 to trigger WUS to request the second cell 103 to send the second SSB and / or SIB1.

[0195] Step S2108 , the first cell 102 sends indication information to the terminal 101 .

[0196] In some embodiments, the above-mentioned indication information is used to instruct the sending of a wake-up signal. Exemplarily, the above-mentioned indication information is used to instruct the terminal 101 to send a wake-up signal.

[0197] In some embodiments, the indication information is sent by the first cell 102 to the terminal 101, and accordingly, the terminal 101 receives the indication information sent by the first cell 102. Exemplarily, the first cell 102 determines that the terminal 101 needs to wake up the second cell 103 through the WUS based on the RSRP measurement report of the first SSB reported by the terminal 101, and then the first cell 102 sends indication information to the terminal 101 to instruct the terminal 101 to send a wake-up signal.

[0198] In some embodiments, the above-mentioned indication information may be RRC signaling, MAC CE, or DCI information. For example, the first cell 102 may instruct the terminal to send a wake-up signal via RRC signaling / MAC CE / DCI.

[0199] Step S2109 , the terminal 101 sends a wake-up signal to the second cell 103 .

[0200] In some embodiments, the above-mentioned wake-up signal is used to request the second cell 103 to send a second SSB and / or SIB1.

[0201] In some embodiments, the wake-up signal is sent by the terminal 101 to the second cell 103, and accordingly, the second cell 103 receives the wake-up signal sent by the terminal 101. Exemplarily, upon receiving the indication information sent by the first cell 102, the terminal 101 sends a wake-up signal to the second cell 103 to request the second cell 103 to send the second SSB and / or SIB1.

[0202] In some embodiments, the terminal 101 obtains the configuration information of the second cell 103 through the SIB information of the first cell. Based on the configuration information of the second cell 103, the terminal 101 sends the above-mentioned wake-up signal to the second cell 103. Exemplarily, the terminal 101 in the RRC connected state on the first cell 102 can obtain the configuration information of the second cell 103 through the SIB of the first cell. Exemplarily, the terminal 101 in the RRC connected state on the first cell 102 can obtain the configuration information of the second cell 103 from the first cell 102 through dedicated RRC signaling.

[0203] In some embodiments, the terminal 101 may obtain the configuration information of the second cell 103 from the SIB of the first cell 102. Exemplarily, the first cell 102 sends an SIB including the configuration information of the second cell 103, and the terminal 101 in the first cell 102 may obtain the configuration information of the second cell 103 from the SIB.

[0204] In some embodiments, the terminal 101 may obtain the configuration information of the second cell 103 from dedicated RRC signaling of the first cell 102. Exemplarily, the first cell 101 sends the configuration information of the second cell 103 to the terminal 101 through dedicated RRC signaling, so that the terminal 101 obtains the configuration information of the second cell 103.

[0205] In some embodiments, the configuration information of the second cell 103 may include but is not limited to at least one of the following: an identifier and / or frequency of the second cell; configuration information related to the random access channel RACH of the second cell; configuration information related to the wake-up signal associated with the second cell; information in the SIB1 of the second cell. In some embodiments, the configuration information related to the wake-up signal may include but is not limited to at least one of the following: a preamble index (reamble index) or sequence reserved for the wake-up signal; configuration information of a random access opportunity (RACH Occasion, RO) resource, the RO resource being used to send the wake-up signal; the initial transmit power of the wake-up signal, or a parameter for calculating the initial transmit power. Exemplarily, the terminal 101 may send the wake-up signal to the second cell 103 based on the configuration information of the second cell 103 and / or the configuration information related to the wake-up signal associated with the second cell 103.

[0206] It is worth noting that the terminal 101 can request the second cell 103 to send the second SSB and / or SIB1 through a wake-up signal. In some embodiments, the wake-up signal used to request the second cell 103 to send the second SSB may be the same as or different from the wake-up signal used to request the second cell 103 to send SIB1. Exemplarily, the terminal may request the second cell 103 to send the second SSB through a first WUS, and the terminal may request the second cell 103 to send SIB1 through a second WUS, wherein the first WUS and the second WUS may be the same as or different. Exemplarily, the terminal may request the second cell 103 to send the second SSB through a WUS, and the terminal may request the second cell 103 to send SIB1 through other information; or, the terminal may request the second cell 103 to send the second SSB through other information, and the terminal may request the second cell 103 to send SIB1 through a WUS, and the other information may not be a WUS, and this disclosure does not limit this.

[0207] It should be noted that, in some embodiments, the first cell 102 may be associated with one or more second cells, and the configuration information related to the wake-up signals associated with the one or more second cells may be the same or different. For example, the one or more second cells may be associated with different configuration information related to the wake-up signals, and for example, the one or more second cells may be associated with the same configuration information related to the wake-up signal. For example, the first cell 102 may be associated with one or more second cells, and the terminal 101 may send a wake-up signal to at least some of the one or more second cells 103 associated with the first cell 102. For example, the first cell 102 may be associated with one or more second cells, and the terminal 101 may send a wake-up signal to at least some of the one or more second cells 103 associated with the first cell 102. In this case, sending a wake-up signal to at least some of the one or more second cells 103 associated with the first cell 102 may mean sending a wake-up signal to one or more of the one or more second cells 103 associated with the first cell 102, or sending a wake-up signal to all of the second cells 103 associated with the first cell 102. When there is more than one second cell 103, the wake-up signal is sent using the respective wake-up signal configuration information of the more than one second cells 103. For example, second cell 1, second cell 2, and second cell 3 are network energy-saving cells associated with the first cell 102. The terminal may use the wake-up signal configuration information associated with second cell 1 to send a wake-up signal to second cell 1, and use the wake-up signal configuration information associated with second cell 2 to send a wake-up signal to second cell 2. The wake-up signal configuration information associated with second cell 1, second cell 2, and second cell 3 may be the same or different. In this case, taking the case where the relevant configuration information of the wake-up signals associated with at least some of the second cells is the same, the terminal 101 may send the wake-up signal to the at least some of the second cells based on the configuration information of the at least some of the second cells and / or the relevant configuration information of the same wake-up signal associated with the at least some of the second cells. For example, the first cell 102 is associated with the second cell a and the second cell b, and the relevant configuration information of the wake-up signals associated with the second cell a and the second cell b can be the same. The terminal 101 can send the wake-up signal to the second cell a and the second cell b respectively based on the configuration information of the second cell a and the second cell b and / or the relevant configuration information of the same wake-up signal associated with the second cell a and the second cell b.

[0208] Taking the relevant configuration information of different wake-up signals associated with at least part of the second cells as an example, the terminal 101 can send the wake-up signal to the at least part of the second cells based on the configuration information of the at least part of the second cells and / or the relevant configuration information of the wake-up signals associated with the at least part of the second cells. For example, the first cell 102 is associated with the second cell a and the second cell b, and the relevant configuration information of the wake-up signal associated with the second cell a is different from the relevant configuration information of the wake-up signal associated with the second cell b. For example, the wake-up signal associated with the second cell a is called wake-up signal 1, and the wake-up signal associated with the second cell b is 2. The terminal 101 can send the wake-up signal 1 to the second cell a based on the configuration information of the second cell a and / or the relevant configuration information of the wake-up signal 1 associated with the second cell a, and send the wake-up signal 2 to the second cell b based on the configuration information of the second cell b and / or the relevant configuration information of the wake-up signal 2 associated with the second cell b.

[0209] Optionally, in some embodiments, the first cell 102 can be associated with one or more second cells 103, and the terminal can determine based on the terminal implementation to send a wake-up signal to a second cell associated with the first cell 102, or to send a wake-up signal to multiple second cells associated with the first cell 102, or to send a wake-up signal to all second cells associated with the first cell 102.

[0277] Step S2406, the terminal 101 sends the RSRP measurement report of the first SSB to the first cell 102.

[0278] In some embodiments, the RSRP measurement report of the first SSB can be used by the first cell 102 to determine whether it is necessary to send first information to the second cell 103, and the first information is used to request the second cell 103 to send the second SSB and / or SIB1. Exemplarily, the RSRP measurement report of the first SSB can be used by the first cell 102 to determine whether to trigger the second cell 103 to wake up and send the second SSB and / or SIB1. It should be noted that, in the embodiments of the present disclosure, the first SSB is the synchronization signal block sent by the first cell 102, and the second SSB is the synchronization signal block sent by the second cell 103.

[0279] In some embodiments, when the RSRP measurement result of the first SSB is less than or equal to the first threshold, the terminal 101 reports the RSRP measurement report of the first SSB to the first cell 102. Accordingly, the first cell 102 can receive the RSRP measurement report of the first SSB sent by the terminal 101. In some embodiments, the terminal 101 can periodically send the RSRP measurement report of the first SSB to the first cell 102. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the first SSB to the first cell 102, so that the first cell 102 determines whether to trigger the second cell 103 to wake up and send the second SSB and / or SIB1 based on the RSRP measurement report of the first SSB.

[0281] Exemplarily, the first cell 102 may determine whether the terminal 101 needs to wake up the second cell 103 to send the second SSB and / or SIB1 based on the RSRP measurement report of the first SSB reported by the terminal 101. For example, the first cell 102 determines that the RSRP of the first SSB is less than or equal to the first threshold based on the RSRP measurement report of the first SSB reported by the terminal 101, and may determine that the second cell 103 needs to be woken up so that the second cell 103 wakes up to send the second SSB and / or SIB1. Exemplarily, the first cell 102 determines that the second cell 103 needs to be woken up based on network implementation so that the second cell 103 wakes up to send the second SSB and / or SIB1.

[0282] Step S2408 : The first cell 102 sends first information to the second cell 103 .

[0283] In some embodiments, the first information is sent by the first cell 102 to the second cell 103, and accordingly, the second cell 103 receives the first information sent by the first cell 102. Exemplarily, the first cell 102 determines that the second cell 103 needs to be awakened based on the RSRP measurement report of the first SSB, and wakes up the second cell 103 by sending the first information to the second cell 103 to send the second SSB and / or SIB1. Exemplarily, the first cell 102 determines that the second cell 103 needs to be awakened based on network implementation, and wakes up the second cell 103 by sending the first information to the second cell 103 to send the second SSB and / or SIB1.

[0284] In some embodiments, the first information may be Xn signaling between base stations, or the first information may be included in the Xn signaling. Exemplarily, the first cell 102 may wake up the second cell 103 through Xn signaling between base stations.

[0285] In some embodiments, the first information may be a handover request (HO request). Exemplarily, the first cell 102 may wake up the second cell 103 through the HO request. In one possible implementation, the HO request may implicitly wake up the second cell 103, and the second cell 103 wakes up and sends the second SSB and / or SIB1 upon receiving the HO request. In another possible implementation, the HO request may explicitly wake up the second cell 103, define a new indication bit in the HO request, and use the indication bit to explicitly wake up the second cell 103 and send the second SSB and / or SIB1. Optionally, the first information may also be other Xn signaling, which is not specifically limited in the present disclosure.

[0286] Step S2409, the second cell 103 sends a second SSB and / or SIB1.

[0287] The optional implementation of step S2409 can refer to the optional implementation of step S2110 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0288] The method involved in the embodiment of the present disclosure may include at least one of steps S2401 to S2409.

[0448] It is worth noting that in the SSB / SIB1-less cell scenario, the terminal resides on the anchor / normal cell, and the SSB / SIB1-less cell without DRS is an invisible cell for the terminal. In order to solve the problem of when a terminal in the RRC connected state can trigger WUS to request the SSB / SIB1-less cell to send SSB and / or SIB1 in the SSB / SIB1-less cell scenario, this disclosure proposes a communication method. The details are as follows:

[0449] In some embodiments, the terminal measures the SSB of the first cell and reports the measurement report to the network device (such as the network device associated with the first cell), and the network device triggers the second cell to wake up and send SSB and / or SIB1.

[0450] In some embodiments, the terminal is in an RRC connected state, measures the SSB of a first cell, obtains a measured RSRP, and reports the measurement report to a network device. Exemplarily, the terminal determines that the measured RSRP value is less than or equal to a first threshold, and reports the measurement report to the network device. The first threshold is obtained by the terminal from a measurement configuration of the first cell. Exemplarily, the terminal periodically reports the measurement report to the network device.

[0451] In some embodiments, the network device determines, based on the measurement report reported by the terminal, whether it is necessary to wake up the second cell to send the SSB and / or SIB1. The network device determines that the second cell needs to be woken up and wakes up the second cell through Xn signaling between base stations. Exemplarily, the second cell can be woken up through an HO request (handover request). Specifically, the HO request can implicitly wake up the second cell. The second cell wakes up and sends the SSB and / or SIB1 upon receiving the HO request. Specifically, the HO request can explicitly wake up the second cell. A new indicator bit is defined in the HO request, and the indicator bit is used to indicate the wakeup of the second cell.

[0454] In some embodiments, the network device determines, based on the measurement report reported by the terminal, whether the terminal needs to wake up the second cell through a WUS to send an SSB and / or SIB1. The network device determines that the terminal needs to wake up the second cell through a WUS, and the network device instructs the terminal to send a WUS. Exemplarily, the network device instructs the terminal to send a WUS through RRC signaling / MAC CE / DCI. The terminal receives the instruction from the network device and sends a WUS to request the second cell to send an SSB and / or SIB1.

[0457] In some embodiments, the terminal is in an RRC connected state, measures the SSB of a first cell, obtains a measured RSRP, determines that the measured RSRP is less than or equal to a first threshold, and transmits a WUS requesting the second cell to transmit the SSB and / or SIB1.
