[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] In some embodiments, the first cell 102 may be a normal cell under a network device, and the second cell 103 may belong to the same network device as the first cell 102, or may belong to a different network device. For example, the network device associated with the first cell 102 may be referred to as a first network device, and the network device associated with the second cell 103 may be referred to as a second network device. The first network device and the second network device may be the same network device or different network devices.

[0145] In some embodiments, the network device associated with the first cell 102 (hereinafter referred to as the first network device) may be an access network device. The network device associated with the second cell 103 (hereinafter referred to as the second network device) may also be an access network device. In some embodiments, the access network device is, for example, a node or device that accesses a terminal device to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (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 base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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).

[0151] 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.

[0152] 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.

[0153] 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).

[0154] 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.

[0155] The embodiments of the present disclosure provide a communication method and apparatus thereof, by which, in an SSB / SIB1-less cell scenario, a terminal within the coverage of a first cell can determine whether it is necessary to request a second cell (such as an SSB / SIB1-less cell) to send a first SSB and / or SIB1 based on a measured DRS, so that the terminal within the coverage of the first cell can communicate with the second cell.

[0156] 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.

[0157] Step S2101 : The first cell 102 sends the DRS measurement configuration of the second cell 103 .

[0158] In some embodiments, the DRS measurement configuration of the second cell 103 may be sent by the first cell 102 to the terminal 101. In some embodiments, the DRS measurement configuration of the second cell 103 may be sent by the first network device to the terminal 101 via the first cell 102. Exemplarily, the first cell 102 sends the DRS measurement configuration of the second cell 103 to the terminal 101, and accordingly, the terminal 101 receives the DRS measurement configuration of the second cell 103 sent by the first cell 102. In some embodiments, the DRS measurement configuration of the second cell 103 may be used by the terminal 101 to measure the DRS of the second cell 103, so that the terminal 101 determines whether to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement of the second cell 103. It should be noted that, in some embodiments, the first SSB herein may refer to the synchronization signal block sent by the second cell 103. In some embodiments, "first cell", "first network device", "first base station", etc. may be interchangeable.

[0159] In some embodiments, the terminal 101 is in an RRC connected state on the first cell 102, and the DRS measurement configuration of the second cell 103 may be sent to the terminal by the first cell 102 through dedicated RRC signaling. Exemplarily, the terminal 101 is in an RRC connected state on the first cell 102, and the first cell 102 sends dedicated RRC signaling to the terminal 101.

Exemplarily, the terminal 101 is in the RRC_IDLE state / RRC_INACTIVE state on the first cell 102, and the first cell 102 sends the SIB to the terminal 101. Accordingly, the terminal 101 receives the SIB sent by the first cell 102, and the SIB includes the DRS measurement configuration of the second cell 103.

[0161] In some embodiments, the DRS measurement configuration of the second cell 103 can only be sent to the terminal through the SIB of the first cell 102.

[0164] In some embodiments, the terminal 101 determines whether to request the second cell 103 to transmit the first SSB based on the DRS measurement of the second cell 103 and the first threshold. In some embodiments, the first threshold may be configured per beam granularity, where the beam may be a CSI-RS (Channel State Information Reference Signal) or an SSB. Alternatively, the first threshold may be configured per beam group granularity. Exemplarily, the first threshold may be configured per CSI-RS granularity, or per CSI-RS group granularity, or per SSB index granularity, or per SSB index group granularity, or per CSI-RS and SSB index group granularity. The measurement value used for evaluation may be per beam, i.e., per CSI-RS or SSB.

Exemplarily, the terminal 101 is in the RRC_IDLE state / RRC_INACTIVE state on the first cell 102, and the first cell 102 sends the SIB to the terminal 101. Accordingly, the terminal 101 receives the SIB sent by the first cell 102, and the SIB includes the above-mentioned SSB measurement configuration.

[0180] In some embodiments, the SSB measurement configuration can only be sent to the terminal through the SIB of the first cell 102. Exemplarily, the terminal 101 is in any of the following states on the first cell 102: RRC connected state, RRC_IDLE state / RRC_INACTIVE state, and the first cell 102 can only broadcast the SSB measurement configuration through the SIB. Accordingly, the terminal 101 in any of the following states on the first cell 102: RRC connected state, RRC_IDLE state / RRC_INACTIVE state obtains the SSB measurement configuration through the SIB of the first cell 102.

[0181] In some embodiments, step S2101 and step S2103 may be executed in an interchanged order or simultaneously.

[0182] In step S2104, the terminal 101 measures the second SSB sent by the first cell 102 based on the SSB measurement configuration, and obtains the second SSB measurement result of the first cell 102.

[0183] In some embodiments, the terminal 101 obtains the above-mentioned SSB measurement configuration sent by the first cell 102, and can measure the RSRP value of the second SSB sent by the first cell 102 based on the SSB measurement configuration to obtain the RSRP measurement result of the second SSB. The RSRP measurement result of the second SSB is the RSRP measurement result of the second SSB of the first cell 102.

[0184] In step S2105 , the terminal 101 determines that it needs to request the second cell 103 to send the first SSB and / or SIB1.

[0185] In some embodiments, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102.

[0186] In some embodiments, the terminal 101 determines whether it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102. Exemplarily, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102.

[0187] Exemplarily, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103. Exemplarily, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the second SSB measurement result of the first cell 102. Exemplarily, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and the second SSB measurement result of the first cell 102.

[0188] Step S2106 , the terminal 101 sends first information to the second cell 103 .

[0189] In some embodiments, the above-mentioned first information is used to request the second cell 103 to send the first SSB and / or SIB1.

[0190] In some embodiments, the first information may be a wake-up signal (WUS), or the first information may be included in the wake-up signal.

[0191] In some embodiments, the first information may be sent by the terminal 101 to the second cell 103, and accordingly, the second cell 103 receives the first information sent by the terminal 101. Exemplarily, the terminal 101 sends the first information to the second cell 103 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102, to request the second cell 103 to send the second SSB and / or SIB1.

[0192] In some embodiments, the terminal 101 determines whether it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102. Exemplarily, the terminal 101 determines that it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the DRS measurement result of the second cell 103 and / or the second SSB measurement result of the first cell 102, then the terminal 101 sends first information to the second cell 103 to request the second cell 103 to send the second SSB and / or SIB1. Exemplarily, the terminal 101 is in any of the following states on the first cell 102: RRC connected state, RRC_IDLE state / RRC_INACTIVE state.

[0193] Exemplarily, when the DRS measurement result of the second cell 103 is greater than or equal to the corresponding first threshold, the terminal 101 sends the above-mentioned first information to the second cell 103 to request the second cell to send the first SSB and / or SIB1.

[0194] Exemplarily, when the DRS measurement result of the second cell 103 is greater than or equal to the first threshold and the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, the terminal 101 sends the above-mentioned first information to the second cell 103 to request the second cell to send the first SSB and / or SIB1.

[0195] Exemplarily, when the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, the terminal 101 sends the above-mentioned first information to the second cell 103 to request the second cell to send the first SSB and / or SIB1.

[0196] In some embodiments, the terminal 101 may obtain the configuration of the second cell 103 from the SIB or dedicated RRC signaling of the first cell 102. Based on the configuration of the second cell 103, the terminal 101 sends the first information to the second cell 103 to request the second cell to send the first SSB and / or SIB1. Exemplarily, the first cell 102 sends the SIB or dedicated RRC signaling, and accordingly, the terminal receives the SIB or dedicated RRC signaling sent by the first cell 102, where the SIB or dedicated RRC signaling includes the configuration of the second cell 103. The terminal 101 may send the first information to the second cell 103 based on the configuration of the second cell 103.

[0197] In some embodiments, the configuration 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 103; random access channel (RACH)-related configuration information of the second cell 103; configuration of the first information associated with the second cell 103; and information in the SIB1 of the second cell 103. In some embodiments, the configuration of the first information associated with the second cell 103 may 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 occasion (RACH Occasion, RO) resource used to transmit the first information; an initial transmit power of the first information, or a parameter used to calculate the initial transmit power. Exemplarily, the terminal 101 may transmit the first information to the second cell 103 based on the configuration of the second cell 103 and / or the configuration of the first information associated with the second cell 103. The initial transmit power of the first information may refer to the transmit power used by the terminal when transmitting the first information for the first time when determining to transmit the first information to the second cell 103 for the first time.

[0198] In some embodiments, the configuration of the first information associated with the second cell 103 may be obtained by the terminal 101 from the SIB or dedicated RRC signaling of the first cell. For example, the configuration of the first information associated with the second cell 103 is not included in the configuration of the second cell 103, but is separately sent by the first cell 102 to the terminal 101 via the SSB or dedicated RRC signaling. Exemplarily, the first cell 102 sends the SIB or dedicated RRC signaling, and accordingly, the terminal receives the SIB or dedicated RRC signaling sent by the first cell 102, which includes the configuration of the first information associated with the second cell 103, so that the terminal 101 can send the first information to the second cell 103 based on the configuration of the second cell 103 and / or the configuration of the first information associated with the second cell 103.

[0199] It is worth noting that the terminal 101 can request the second cell 103 to send the first SSB and / or SIB1 through the first information. In some embodiments, the first information used to request the second cell 103 to send the first SSB may be the same as or different from the first information used to request the second cell 103 to send SIB1. Exemplarily, the terminal may request the second cell 103 to send the first SSB through the first WUS, and the terminal may request the second cell 103 to send SIB1 through the 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 first SSB through the 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 first SSB through other information, and the terminal may request the second cell 103 to send SIB1 through the WUS, and the other information may not be the WUS, and this disclosure does not limit this.

[0200] It should be noted that, in some embodiments, the first cell 102 may be associated with one or more second cells. The configurations of the first information associated with the one or more second cells may be the same or different. Exemplarily, the one or more second cells may be associated with different configurations of the first information. Exemplarily, the one or more second cells may be associated with the same configuration of the first information. For example, the first cell 102 may be associated with one or more second cells, and the terminal 101 may send the first information 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 the first information to at least some of the one or more second cells 103 associated with the first cell 102. Sending the first information to at least some of the one or more second cells 103 associated with the first cell 102 may mean sending the first information to one or more of the one or more second cells 103 associated with the first cell 102, or sending the first information to all of the second cells 103 associated with the first cell 102. When there is more than one second cell 103, the first information is sent using the first information configurations of the more than one second cells 103. For example, the second cell 1, the second cell 2, and the second cell 3 are respectively network energy-saving cells associated with the first cell 102. The terminal can use the configuration of the first information associated with the second cell 1 to send the first information to the second cell 1, and use the configuration of the first information associated with the second cell 2 to send the first information to the second cell 2. The configurations of the first information associated with the second cell 1, the second cell 2, and the second cell 3 can be the same or different. In particular, taking the same configuration of the first information associated with at least some of the second cells as an example, the terminal 101 can send the first information to the at least some of the second cells based on the configuration of the at least some of the second cells and / or the configuration of the same first information associated with the at least some of the second cells. For example, taking the first cell 102 as being associated with the second cell a and the second cell b, the configuration of the first information associated with the second cell a and the second cell b can be the same. The terminal 101 can send the first information to the second cell a and the second cell b based on the configuration of the second cell a and the second cell b and / or the configuration of the same first information associated with the second cell a and the second cell b.

[0201] Taking the configuration in which at least part of the second cells are respectively associated with different first information as an example, the terminal 101 can send the first information to the at least part of the second cells based on the configuration of the at least part of the second cells and / or the configuration of the first information 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 configuration of the first information associated with the second cell a is different from the configuration of the first information associated with the second cell b. For example, the first information associated with the second cell a is called first information 1, and the first information associated with the second cell b is 2. The terminal 101 can send the first information 1 to the second cell a based on the configuration of the second cell a and / or the configuration of the first information 1 associated with the second cell a, and send the first information 2 to the second cell b based on the configuration of the second cell b and / or the configuration of the first information 2 associated with the second cell b.

[0202] 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 terminal implementation whether to send the first information to a second cell associated with the first cell 102, or to send the first information to multiple second cells associated with the first cell 102, or to send the first information to all second cells associated with the first cell 102.

[0203] Step S2107, the second cell 103 sends the first SSB and / or SIB1.

[0204] In some embodiments, the second cell 103 receives the first information, and the second cell 103 sends the first SSB and / or SIB1 to the terminal 101. Accordingly, the terminal 101 receives the first SSB and / or SIB1 sent by the second cell 103. In some embodiments, the first SSB and / or SIB1 may be sent to the terminal 101 by the second network device via the second cell 103. The second network device is a network device associated with the second cell 103. In some embodiments, "second cell", "second network device", "second base station", etc. may be interchangeable.

[0205] For example, the terminal 101 may request the second cell 103 to send a first SSB through the first information. In some embodiments, the first SSB is used for the terminal 101 to synchronize with the second cell 103. For example, the second cell 103 sends the first SSB to the terminal 101 to facilitate the terminal 101 to search and identify the cell.

[0206] Exemplarily, the terminal 101 may request the second cell 103 to send SIB1 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), or SIB1 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 is not limited to this and will not be described in detail.

[0207] It should be noted that, in some embodiments, the DRS of the second cell 103 may be a synchronization signal block or other reference signal of the second cell 103. In some embodiments, for the second cell 103 with a synchronization signal block, the terminal 101 may request the second cell 103 to send SIB1, and the synchronization signal block of the second cell 103 may be used as the DRS of the second cell 103. Exemplarily, the terminal 101 may determine whether it is necessary to request the second cell 103 to send SIB1 based on the measured synchronization signal block of the second cell 103. For example, the terminal 101 may determine whether it is necessary to send first information to the second cell 103 to request the second cell 103 to send SIB1 based on the measured synchronization signal block of the second cell 103. In some embodiments, other reference signals may be used as DRS, and the terminal may determine whether it is necessary to request the second cell 103 to send the first SSB and / or SIB1 based on the measured other reference signals of the second cell 103. For example, the terminal may determine whether it is necessary to send first information to the second cell 103 to request the second cell 103 to send the first SSB and / or SIB1 based on the measured other reference signals of the second cell 103.

[0214] The method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2107. For example, step S2101+step S2102+step S2105+step S2106 can be implemented as an independent embodiment, step S2101+step S2102+step S2105+step S2106+step S2107 can be implemented as an independent embodiment, step S2103+step S2104+step S2105+step S2106 can be implemented as an independent embodiment, and step S2103+step S2104+step S2105+step S2106 can be implemented as an independent embodiment. 05+step S2106+step S2107 can be implemented as an independent embodiment, step S2101+step S2102+step S2103+step S2104+step S2105+step S2106 can be implemented as an independent embodiment, step S2101+step S2102+step S2103+step S2104+step S2105+step S2106+step S2107 can be implemented as an independent embodiment, but are not limited to this.

[0215] In some embodiments, step S2103, step S2104, and step S2107 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0216] In some embodiments, step S2103 and step S2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0220] Figure 2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, 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.

[0221] Step S2201 : The first cell 102 sends the DRS measurement configuration of the second cell 103 .

[0222] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0223] In step S2202 , the terminal 101 measures the DRS of the second cell 103 based on the DRS measurement configuration of the second cell 103 , and obtains a DRS measurement result of the second cell 103 .

[0224] The optional implementation of step S2202 can refer to the optional implementation of step S2102 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0225] Step S2203: The terminal 101 determines that the DRS measurement result of the second cell 103 is greater than or equal to a first threshold.

[0226] Exemplarily, the terminal 101 compares the DRS measurement result of the second cell 103 (such as the measured RSRP and / or RSRQ and / or SINR value of the DRS of the second cell 103) with the corresponding first threshold. For example, the terminal can determine whether the measured DRS measurement result of the second cell 103 (such as the measured RSRP and / or RSRQ and / or SINR value of the DRS of the second cell 103) is greater than or equal to the corresponding first threshold. If the measured DRS measurement result of the second cell 103 (such as the measured RSRP and / or RSRQ and / or SINR value of the DRS of the second cell 103) is greater than or equal to the corresponding first threshold, it can be considered that the DRS measurement result of the second cell 103 is greater than or equal to the corresponding first threshold.

[0227] 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 DRS measurement configuration of the second cell 103. Exemplarily, the DRS measurement configuration of the second cell 103 sent by the first cell 102 to the terminal 101 includes the first threshold, and the first threshold may be used by the terminal 101 to determine whether to report the DRS measurement report of the second cell 103 based on the DRS measurement result of the second cell 103. Exemplarily, the terminal 101 may obtain the first threshold from the DRS measurement configuration of the second cell 103, so that the terminal 101 can determine the signal quality of the DRS of the second cell 103 based on the first threshold.

[0228] In step S2204 , the terminal 101 determines to report the DRS measurement report of the second cell 103 .

[0229] In some embodiments, the terminal 101 determines whether to report the DRS measurement report of the second cell 103 based on the DRS measurement result of the second cell 103. Exemplarily, if the terminal 101 determines that the DRS measurement result of the second cell 103 is greater than or equal to the first threshold, it determines that the DRS measurement report of the second cell 103 needs to be reported to the first cell 102, so that the first cell 102 can determine whether to send first indication information to the terminal 101 based on the DRS measurement report of the second cell 103 to instruct the terminal 101 to send the first information, that is, the first cell 102 triggers the terminal 101 to send the first information based on the DRS measurement report of the second cell 103 to request the second cell 103 to send the first SSB and / or SIB1. Exemplarily, the terminal 101 periodically reports the DRS measurement report of the second cell 103 to the first cell 102, so that the first cell 102 can determine whether to send the first indication information to the terminal 101 based on the DRS measurement report of the second cell 103 to instruct the terminal 101 to send the above-mentioned first information.

[0230] In step S2205 , the terminal 101 sends the DRS measurement report of the second cell 103 to the first cell 102 .

[0231] In some embodiments, the terminal 101 is in an RRC state on the first cell 102 , or the terminal 101 enters an RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102 .

[0232] In some embodiments, the DRS measurement report of the second cell 103 may be used by the first cell to determine whether to send first indication information, where the first indication information is used to instruct the terminal to send the first information. Exemplarily, the DRS measurement report of the second cell 103 may be used by the first cell 102 to determine whether it is necessary to trigger the terminal 101 to send the first information, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0233] In some embodiments, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and when the DRS measurement result of the second cell 103 is greater than or equal to a first threshold, the terminal 101 reports the DRS measurement report of the second cell 103 to the first cell 102. Or when the DRS measurement result of the second cell 103 is greater than or equal to the first threshold, the terminal 101 is in an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and reports the DRS measurement report of the second cell 103 to the first cell 102. Accordingly, the first cell 102 can receive the DRS measurement report of the second cell 103 sent by the terminal 101. In some embodiments, the terminal 101 may periodically send the DRS measurement report of the second cell 103 to the first cell 102. Exemplarily, the terminal 101 periodically reports the DRS measurement report of the second cell 103 to the first cell 102, so that the first cell 102 determines whether to send first indication information to the terminal 101 based on the DRS measurement report of the second cell 103, so as to instruct the terminal 101 to send the first information.

[0234] It should be noted that, in some embodiments, step S2203 and step S2204 are optional. That is, the terminal 101 is in the RRC state on the first cell 102, or the terminal 101 enters the RRC state from the RRC non-connected state (such as RRC_IDLE state or RRC_INACTIVE state) in the first cell 102, the terminal 101 obtains the DRS measurement result of the second cell 103, and the DRS measurement report of the second cell 103 can be sent to the first cell 102. Alternatively, the terminal 101 is in the RRC state on the first cell 102, or the terminal 101 enters the RRC state from the RRC non-connected state (such as RRC_IDLE state or RRC_INACTIVE state) in the first cell 102, the terminal 101 obtains the DRS measurement result of the second cell 103, and only when it is determined that the DRS measurement result of the second cell 103 is greater than or equal to the first threshold, will the DRS measurement report of the second cell 103 be sent to the first cell 102.

[0235] Step S2206: The first cell 102 sends an SSB measurement configuration.

[0236] The optional implementation of step S2206 can refer to the optional implementation of step S2103 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0237] In step S2207, the terminal 101 measures the second SSB sent by the first cell 102 based on the SSB measurement configuration, and obtains the second SSB measurement result of the first cell 102.

[0238] The optional implementation of step S2207 can refer to the optional implementation of step S2104 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0239] In step S2208, the terminal 101 determines that the second SSB measurement result of the first cell 102 is less than or equal to the second threshold.

[0240] Exemplarily, the terminal 101 compares the second SSB measurement result of the first cell 102 (such as the measured RSRP value of the second SSB of the first cell 102) with the second threshold. For example, the terminal can determine whether the measured second SSB measurement result of the first cell 102 (such as the measured RSRP value of the second SSB of the first cell 102) is less than or equal to the second threshold. If the measured second SSB measurement result of the first cell 102 (such as the measured RSRP value of the second SSB of the first cell 102) is less than or equal to the second threshold, it can be considered that the second SSB measurement result of the first cell 102 is less than or equal to the second threshold.

[0241] In some embodiments, the second threshold may be preconfigured. Alternatively, in some embodiments, the second threshold may be obtained by the terminal 101 from the SSB measurement configuration. Exemplarily, the first cell 102 includes the second threshold in the SSB measurement configuration sent to the terminal 101. The second threshold may be used by the terminal 101 to determine whether to report the second SSB measurement report of the first cell 102 based on the second SSB measurement result of the first cell 102. Exemplarily, the terminal 101 may obtain the second threshold from the SSB measurement configuration, so that the terminal 101 can determine the signal quality of the second SSB of the first cell 102 based on the second threshold.

[0242] In step S2209 , the terminal 101 determines to report the second SSB measurement report of the first cell 102 .

[0243] In some embodiments, terminal 101 determines whether to report a second SSB measurement report of first cell 102 based on a second SSB measurement result of first cell 102. Exemplarily, if terminal 101 determines that the second SSB measurement result of first cell 102 is less than or equal to a second threshold, terminal 101 determines that the second SSB measurement report of first cell 102 needs to be reported to first cell 102, so that first cell 102 can determine, based on the second SSB measurement report of first cell 102, whether to send first indication information to terminal 101 to instruct terminal 101 to send first information, i.e., so that first cell 102 triggers terminal 101 to send first information based on the second SSB measurement report of first cell 102 to request second cell 103 to send the first SSB and / or SIB1. Exemplarily, terminal 101 periodically reports the second SSB measurement report of first cell 102 to first cell 102, so that first cell 102 can determine, based on the second SSB measurement report of first cell 102, whether to send first indication information to terminal 101 to instruct terminal 101 to send the above-mentioned first information.

[0244] In step S2210 , the terminal 101 sends the second SSB measurement report of the first cell 102 to the first cell 102 .

[0245] In some embodiments, the terminal 101 is in an RRC state on the first cell 102 , or the terminal 101 enters an RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102 .

[0246] In some embodiments, the second SSB measurement report of the first cell 102 may be used by the first cell 102 to determine whether to send first indication information, where the first indication information is used to instruct the terminal 101 to send the first information. Exemplarily, the second SSB measurement report of the first cell 102 may be used by the first cell 102 to determine whether it is necessary to trigger the terminal 101 to send the first information, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0247] In some embodiments, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and when the second SSB measurement result of the first cell 102 is less than or equal to a second threshold, the terminal 101 reports the second SSB measurement report of the first cell 102 to the first cell 102. Or when the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, the terminal 101 is in an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and reports the second SSB measurement report of the first cell 102 to the first cell 102. Accordingly, the first cell 102 may receive the second SSB measurement report of the first cell 102 sent by the terminal 101. In some embodiments, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 may periodically send the second SSB measurement report of the first cell 102 to the first cell 102. Exemplarily, the terminal 101 periodically reports the second SSB measurement report of the first cell 102 to the first cell 102, so that the first cell 102 determines whether to send first indication information to the terminal 101 based on the second SSB measurement report of the first cell 102, so as to instruct the terminal 101 to send the first information.

[0248] It should be noted that, in some embodiments, steps S2208 and S2209 are optional. That is, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 obtains the second SSB measurement result of the first cell 102, and can send the second SSB measurement report of the first cell 102 to the first cell 102. Alternatively, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 obtains the second SSB measurement result of the first cell 102, and only when it is determined that the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, will the second SSB measurement report of the first cell 102 be sent to the first cell 102.

[0249] Step S2211 : The first cell 102 determines that it needs to send first indication information to the terminal 101 .

[0250] In some embodiments, the first indication information is used to instruct the terminal 101 to send the first information to request the second cell 103 to send the first SSB and / or SIB1.

[0251] In some embodiments, the first cell 102 determines whether it is necessary to send first indication information to the terminal 101 based on the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103. Exemplarily, when the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, it determines that it is necessary to send the first indication information to the terminal 101. For example, when the first cell 102 receives the second SSB measurement report of the first cell 102, the first indication information is sent to the terminal 101. For another example, when the first cell 102 receives the DRS measurement report of the second cell 103, the first indication information is sent to the terminal 101. For another example, when the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, the first indication information is sent to the terminal 101.

[0252] In some embodiments, the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, and may determine whether it is necessary to send the first indication information to the terminal 101 based on network implementation. Exemplarily, the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the first indication information to the terminal 101. For example, the first cell 102 receives the second SSB measurement report of the first cell 102, and determines based on network implementation that it is necessary to send the first indication information to the terminal 101. For another example, the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the first indication information to the terminal 101. For another example, the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the first indication information to the terminal 101.

[0253] Step S2212: The first cell 102 sends first indication information.

[0254] In some embodiments, the first indication information is sent by the first cell 102 to the terminal 101. In some embodiments, the first indication information may be sent by the first network device to the terminal 101 via the first cell 102. Accordingly, the terminal 101 receives the first 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 first information based on the RSRP measurement report of the first SSB reported by the terminal 101 and / or the DRS measurement report of the second cell 103. Then, the first cell 102 sends the first indication information to the terminal 101 to instruct the terminal 101 to send the first information.

[0255] In some embodiments, the first indication information may be RRC signaling, MAC CE, or DCI information. For example, the first cell 102 may instruct the terminal to send the first information via RRC signaling / MAC CE / DCI.

[0256] Step S2213 , the terminal 101 sends first information to the second cell 103 .

[0257] In some embodiments, the above-mentioned first information is used to request the second cell 103 to send the first SSB and / or SIB1.

[0258] In some embodiments, the first information may be a wake-up signal (WUS), or the first information may be included in the wake-up signal.

[0259] In some embodiments, the terminal 101 receives the first indication information sent by the first cell 102 via the first network device, and sends the first information to the second cell 103. The first information may be sent by the terminal 101 to the second cell 103, and accordingly, the second cell 103 receives the first information sent by the terminal 101. Exemplarily, upon receiving the first indication information sent by the first cell 102, the terminal 101 sends the first information to the second cell 103 to request the second cell 103 to send the second SSB and / or SIB1.

[0260] In some embodiments, the terminal 101 may obtain the configuration of the second cell 103 from the SIB or dedicated RRC signaling of the first cell 102. Based on the configuration of the second cell 103, the terminal 101 sends the first information to the second cell 103 to request the second cell to send the first SSB and / or SIB1. Exemplarily, the first cell 102 sends the SIB or dedicated RRC signaling, and accordingly, the terminal receives the SIB or dedicated RRC signaling sent by the first cell 102, and the SIB or dedicated RRC signaling includes the configuration of the second cell 103. The terminal 101 may send the first information to the second cell 103 based on the configuration of the second cell 103. The implementation method of the configuration of the second cell 103 can be referred to the relevant description of the configuration of the second cell 103 in the above step S2106, which will not be repeated here.

[0261] In some embodiments, the configuration of the first information associated with the second cell 103 may be obtained by the terminal 101 from the SIB or dedicated RRC signaling of the first cell. For example, the configuration of the first information associated with the second cell 103 is not included in the configuration of the second cell 103, but is separately sent to the terminal 101 by the first cell 102 through the SSB or dedicated RRC signaling. Exemplarily, the first cell 102 sends the SIB or dedicated RRC signaling, and accordingly, the terminal receives the SIB or dedicated RRC signaling sent by the first cell 102, and the SIB or dedicated RRC signaling includes the configuration of the first information associated with the second cell 103, so that the terminal 101 can send the first information to the second cell 103 based on the configuration of the second cell 103 and / or the configuration of the first information associated with the second cell 103.

[0280] In step S2304 , the terminal 101 determines to report the DRS measurement report of the second cell 103 .

[0281] In some embodiments, the DRS measurement report of the second cell 103 is used by the first cell 102 to determine whether it is necessary to send second information to the second cell 103, and the second information is used to request the second cell 103 to send the first SSB and / or SIB1.

[0282] In some embodiments, the terminal 101 determines whether to report the DRS measurement report of the second cell 103 based on the DRS measurement result of the second cell 103. Exemplarily, if the terminal 101 determines that the DRS measurement result of the second cell 103 is greater than or equal to the first threshold, it determines that the DRS measurement report of the second cell 103 needs to be reported to the first cell 102, so that the first cell 102 can determine whether it needs to send the above-mentioned second information to the second cell 103 based on the DRS measurement report of the second cell 103 to request the second cell 103 to send the first SSB and / or SIB1.

[0283] In step S2305 , the terminal 101 sends the DRS measurement report of the second cell 103 to the first cell 102 .

[0284] In some embodiments, the terminal 101 is in an RRC state on the first cell 102 , or the terminal 101 enters an RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102 .

[0285] In some embodiments, the DRS measurement report of the second cell 103 may be used by the first cell 102 to determine whether it is necessary to send the second information to the second cell 103.

[0286] In some embodiments, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and when the DRS measurement result of the second cell 103 is greater than or equal to a first threshold, the terminal 101 reports the DRS measurement report of the second cell 103 to the first cell 102. Or when the DRS measurement result of the second cell 103 is greater than or equal to the first threshold, the terminal 101 is in an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and reports the DRS measurement report of the second cell 103 to the first cell 102.

In some embodiments, the terminal 101 may periodically send the DRS measurement report of the second cell 103 to the first cell 102. Exemplarily, the terminal 101 periodically reports the DRS measurement report of the second cell 103 to the first cell 102, so that the first cell 102 determines whether it is necessary to send second information to the second cell 103 based on the DRS measurement report of the second cell 103, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0287] It should be noted that, in some embodiments, step S2303 and step S2304 are optional. That is, the terminal 101 is in the RRC state on the first cell 102, or the terminal 101 enters the RRC state from the RRC non-connected state (such as RRC_IDLE state or RRC_INACTIVE state) in the first cell 102, the terminal 101 obtains the DRS measurement result of the second cell 103, and the DRS measurement report of the second cell 103 can be sent to the first cell 102.

[0296] In some embodiments, the terminal 101 determines whether to report the second SSB measurement report of the first cell 102 based on the second SSB measurement result of the first cell 102. Exemplarily, if the terminal 101 determines that the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, it determines that the second SSB measurement report of the first cell 102 needs to be reported to the first cell 102, so that the first cell 102 can determine whether it needs to send the above-mentioned second information to the second cell 103 based on the second SSB measurement report of the first cell 102, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0297] In step S2310 , the terminal 101 sends the second SSB measurement report of the first cell 102 to the first cell 102 .

[0298] In some embodiments, the terminal 101 is in an RRC state on the first cell 102 , or the terminal 101 enters an RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102 .

[0299] In some embodiments, the second SSB measurement report of the first cell 102 may be used by the first cell 102 to determine whether it is necessary to send the second information to the second cell 103. Exemplarily, the second SSB measurement report of the first cell 102 may be used by the first cell 102 to determine whether it is necessary to send the second information to the second cell 103, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0300] In some embodiments, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and when the second SSB measurement result of the first cell 102 is less than or equal to a second threshold, the terminal 101 reports the second SSB measurement report of the first cell 102 to the first cell 102. Or when the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, the terminal 101 is in an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and reports the second SSB measurement report of the first cell 102 to the first cell 102. Accordingly, the first cell 102 may receive the second SSB measurement report of the first cell 102 sent by the terminal 101. In some embodiments, the terminal 101 may periodically send the second SSB measurement report of the first cell 102 to the first cell 102. Exemplarily, the terminal 101 periodically reports the second SSB measurement report of the first cell 102 to the first cell 102, so that the first cell 102 determines whether it is necessary to send second information to the second cell 103 based on the second SSB measurement report of the first cell 102, so as to request the second cell 103 to send the first SSB and / or SIB1.

[0301] It should be noted that, in some embodiments, steps S2308 and S2309 are optional. That is, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 obtains the second SSB measurement result of the first cell 102, and can send the second SSB measurement report of the first cell 102 to the first cell 102. Alternatively, the terminal 101 is in an RRC state on the first cell 102, or the terminal 101 enters the RRC state from an RRC non-connected state (such as an RRC_IDLE state or an RRC_INACTIVE state) in the first cell 102, and the terminal 101 obtains the second SSB measurement result of the first cell 102, and only when it is determined that the second SSB measurement result of the first cell 102 is less than or equal to the second threshold, will the second SSB measurement report of the first cell 102 be sent to the first cell 102.

[0302] In step S2311 , the first cell 102 determines that second information needs to be sent to the second cell 103 .

[0303] In some embodiments, the first cell 102 determines whether it is necessary to send the second information to the second cell 103 based on the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103. Exemplarily, when the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, it determines that it is necessary to send the second information to the second cell 103. For example, when the first cell 102 receives the second SSB measurement report of the first cell 102, the second information is sent to the second cell 103. For another example, when the first cell 102 receives the DRS measurement report of the second cell 103, the second information is sent to the second cell 103. For another example, when the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, the second information is sent to the second cell 103.

[0304] In some embodiments, the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, and may determine whether it is necessary to send the second information to the second cell 103 based on network implementation. Exemplarily, the first cell 102 receives the second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the second information to the second cell 103. For example, the first cell 102 receives the second SSB measurement report of the first cell 102, and determines based on network implementation that it is necessary to send the second information to the second cell 103. For another example, the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the second information to the second cell 103. For another example, the first cell 102 receives the second SSB measurement report of the first cell 102 and the DRS measurement report of the second cell 103, and determines based on network implementation that it is necessary to send the second information to the second cell 103.

[0305] Step S2312: The first cell 102 sends second information.

[0306] In some embodiments, the second information may be sent by the first cell 102 to the second cell 103. In some embodiments, the second information may be sent by the first network device to the second cell 103 via the first cell 102. Accordingly, the second cell 103 receives the second 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 second SSB measurement report of the first cell 102 and / or the DRS measurement report of the second cell 103, and wakes up the second cell 103 by sending the second information to the second cell 103 to send the first 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 second information to the second cell 103 to send the first SSB and / or SIB1.

[0307] In some embodiments, the second information may be Xn signaling between base stations, or the second 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.

[0308] In some embodiments, the second 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 first 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 first SSB and / or SIB1. Optionally, the second information may also be other Xn signaling, which is not specifically limited in the present disclosure.

[0309] Step S2313, the second cell 103 sends the first SSB and / or SIB1.

[0310] In some embodiments, the second cell 103 receives the above-mentioned second information, and the second cell 103 sends the first SSB and / or SIB1 to the terminal 101. Accordingly, the terminal 101 receives the first SSB and / or SIB1 sent by the second cell 103.

The second cell 103 receives the first information sent by the terminal 101 and sends the first SSB and / or SIB1 to the terminal 101.

[0512] The embodiments of the present disclosure propose a communication method, and the method involved in the embodiments of the present disclosure can be applied to the communication system 100. The method includes but is not limited to the following steps: the terminal 101 measures the DRS of the second cell 103, determines to report the DRS measurement report of the second cell 103 based on the DRS measurement result of the second cell 103, and sends the DRS measurement report of the second cell 103 to the first cell 102. The first cell 102 receives the DRS measurement report of the second cell 103 and determines that it is necessary to send first indication information to the terminal 101. The terminal 101 receives the first indication information sent by the first cell 102 and sends the first information to the second cell 103. The second cell 103 receives the first information sent by the terminal 101 and sends the first SSB and / or SIB1 to the terminal 101.

[0513] The embodiments of the present disclosure provide a communication method, which can be applied to a communication system 100. The method includes but is not limited to the following steps: a terminal 101 measures a DRS of a second cell 103, determines to report a DRS measurement report of the second cell 103 based on the DRS measurement result of the second cell 103, and sends the DRS measurement report of the second cell 103 to the first cell 102. The first cell 102 receives the DRS measurement report of the second cell 103, determines that it needs to request the second cell 103 to send a first SSB and / or SIB1, and sends second information to the second cell 103. The second cell 103 receives the second information sent by the first cell 102, and sends the first SSB and / or SIB1 to the terminal 101.

[0514] The embodiments of the present disclosure provide a communication method that can solve the problem of, in an SSB / SIB1-less cell scenario, a terminal being within the coverage of a first cell and, for a second cell with a DRS (such as an SSB / SIB1-less cell), how the terminal sends first information (such as WUS) based on the measured DRS to request the second cell (such as a sleeping cell, also referred to as a cell in a dormant state) to send SSB and / or SIB1. The following will be described accordingly in conjunction with the embodiments.

[0515] In some embodiments, the terminal measures the DRS of the second cell, and the terminal determines that the DRS measurement result of the second cell is greater than or equal to the first threshold. The terminal sends first information (such as WUS) to request the second cell to send the first SSB and / or SIB1.

[0516] Exemplarily, the terminal measures the DRS of the second cell based on the DRS measurement configuration of the second cell obtained from the SIB / dedicated RRC signaling of the first cell. A terminal in an RRC connected state can obtain the DRS measurement configuration of the second cell through dedicated RRC signaling, and a terminal in an RRC_idle / inactive state can obtain the DRS measurement configuration of the second cell through the SIB. Another possible implementation is that the first cell only broadcasts the DRS measurement configuration of the second cell through the SIB, and all terminals in the RRC connected state / idle / inactive state obtain the DRS measurement configuration of the second cell through the SIB. The DRS measurement configuration of the second cell may include, for example, the DRS period, frequency domain resources, sequence generation related configuration, etc. The DRS measurement configuration of the second cell may also include a threshold configuration based on whether the DRS measurement is close to the sleeping cell (i.e., the first threshold mentioned above), measurement configuration, etc. The threshold configuration may be configured per beam (this beam may be CSI-RS or SSB) or per beam group, and the measurement quantity may be RSRP or RSRQ or SINR, depending on the network side configuration. The threshold configuration can be per CSI-RS or CSI-RS group, per SSB index, per SSB index group, or per CSI-RS and SSB index group. The measurement value used for evaluation can be per beam, i.e., per CSI-RS or SSB.

[0517] Exemplarily, the terminal is in an RRC connected state / idle / inactive state. The terminal determines that the DRS measurement result is greater than or equal to the first threshold based on the measurement result of DRS, and the terminal sends a first information (such as WUS) to request the second cell to send the first SSB and / or SIB1.

[0518] Exemplarily, the terminal obtains the configuration of the first information from the SIB / dedicated RRC signaling of the first cell, the terminal in the RRC connected state can obtain the configuration of the first information through the dedicated RRC signaling, and the terminal in the idle / inactive state can obtain the configuration of the first information through the SIB. Another possible implementation method is that the first cell only broadcasts the configuration of the first information through the SIB, and the terminals in the RRC connected state / idle / inactive state all obtain the configuration of the first information through the SIB. The configuration of the first information includes but is not limited to at least one of the following: a preamble index or sequence reserved for the first information; configuration information of RO resources at the random access opportunity, the RO resources being used to send WUS; parameters for calculating the initial power of sending the first information, or directly the initial power of sending the first information (also referred to as the initial sending power), etc.

[0519] In some embodiments, the terminal measures the DRS of the second cell, and reports the DRS measurement result to the first cell. The first cell instructs the terminal to send first information (such as WUS) to request the second cell to send the first SSB and / or SIB1.

[0520] Exemplarily, the terminal is in an RRC connected state, the terminal measures the DRS of the second cell, obtains the RSRP / RSRQ / SINR value of the measured DRS, and reports the DRS measurement report to the first cell. Exemplarily, the terminal determines that the RSRP / RSRQ / SINR value of the measured DRS is greater than or equal to the first threshold, and the terminal reports the DRS measurement report to the first cell. Exemplarily, the terminal periodically reports the measurement report to the first cell.

[0521] Exemplarily, the first cell instructs the terminal to send first information (such as WUS) through the first indication information based on the DRS measurement report reported by the terminal and / or the SSB measurement report of the first cell to request the second cell to send the first SSB and / or SIB1. Exemplarily, the network device (such as the network device associated with the first cell) instructs the terminal to send the first information (such as WUS) through RRC signaling / MAC CE / DCI, and the terminal receives the first indication information of the network device and sends the first information (such as WUS) to request the second cell to send the first SSB and / or SIB1.

[0522] In some embodiments, the terminal measures the DRS of the second cell, and reports the DRS measurement result to the first cell. The first cell triggers the second cell to wake up and send the first SSB and / or SIB1.

[0523] Exemplarily, the terminal is in an RRC connected state, the terminal measures the DRS of the second cell, obtains the RSRP / RSRQ / SINR value of the measured DRS, and reports the DRS measurement report to the first cell.
