A communication method and device thereof Technical Field
[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method and apparatus thereof. Background Art
[0002] With the gradual application of large-scale active antenna arrays and the large-scale construction of fifth-generation (5G) mobile networks, the energy consumption of wireless communication networks has increased significantly.

[0159] 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 present disclosure. In practical 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.
[0160] 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.
[0161] 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.
[0162] 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.
[0163] 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.
[0164] 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.
[0165] 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.
[0166] 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.
[0167] 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.
[0168] 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.
[0169] 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).
[0170] 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.
[0171] 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 for terminals in the RRC connected state (RRC_CONNECTED), a WUS (wake up signal) is introduced. An offset in front of the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal. During this WUS duration, a WUS signal, i.e., DCI 2-6, is sent, which is encrypted by PS-RNTI (Power Saving RNTI) to indicate whether the terminal wakes up to monitor PDCCH (Physical Downlink Control Channel) during the next UE C-DRX onduration.
[0172] 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).
[0173] 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 the SSB. In some embodiments, the second cell does not have a DRS (discovery reference signal), and in some embodiments, the second cell has a DRS.
[0174] 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 no effective means for determining when a terminal in the RRC_IDLE / INACTIVE state on the first cell requests the network energy-saving cell to send.
[0175] To this end, an embodiment of the present disclosure proposes a communication method, which enables a terminal in the RRC_IDLE / INACTIVE state to request the second cell to send SSB and / or SIB1 through WUS, thereby facilitating the terminal to subsequently communicate with the second cell.
[0176] 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.
[0177] Step S2101 : The terminal 101 obtains measurement configuration information from the first cell 102 .
[0178] 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 association relationship information between the reference signal resource and the measurement report.
[0179] In some embodiments, the above-mentioned measurement configuration information can be used by the terminal 101 to measure the RSRP of the second SSB sent by the first cell 102.
[0180] In some embodiments, the terminal 101 is in an RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, and the terminal 101 may obtain the above-mentioned measurement configuration information through the first SIB information of the first cell 102. In other embodiments, the terminal 101 may also obtain the measurement configuration information when it is in an RRC connected state on the first cell 102. When the terminal 101 switches from the RRC connected state to the non-connected state and then switches back to the RRC connected state, the measurement configuration information may be used to perform measurement, etc.
[0181] In step S2102 , the terminal 101 enters the RRC connected state from the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102 .
[0182] In some embodiments, the terminal 101 is in the RRC_IDLE state on the first cell 102. The terminal 101 may initiate an RRC connection establishment procedure to the first cell 102 to enter the RRC connected state. The terminal 101 is in the RRC_INACTIVE state on the first cell 102. The terminal 101 may initiate an RRC connection recovery procedure to the first cell 102 to enter the RRC connected state.
[0183] Optionally, in some embodiments, step S2101 and step S2102 may be performed in an interchanged order. For example, step S2101 may be performed first and then step S2102. Alternatively, step S2102 may be performed first and then step S2101. In the case where step S2102 is performed first and then step S2101, the terminal 101 enters the RRC connected state from the RRC_IDLE / INACTIVE state on the first cell 102, so that the terminal 101 in the RRC connected state can obtain the above-mentioned measurement configuration information through the first SIB information of the first cell 102, or the terminal 101 in the RRC connected state can also obtain the above-mentioned measurement configuration information from the first cell 102 through dedicated RRC signaling. For example, the terminal 101 enters the RRC connected state from the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, so that the first cell 102 can send the above-mentioned measurement configuration information to the terminal 101 through dedicated RRC signaling. Correspondingly, the terminal 101 in the RRC connected state can obtain the above-mentioned measurement configuration information from the first cell 102 through dedicated RRC signaling.
[0184] In step S2103, the terminal 101 measures the RSRP of the second SSB sent by the first cell 102 based on the measurement configuration information, and obtains the RSRP measurement result of the second SSB.
[0185] In some embodiments, the second SSB is sent by the first cell 102 to the terminal 101 , and accordingly, the terminal 101 receives the second SSB sent by the first cell 102 .
[0186] Exemplarily, the terminal 101 may measure the RSRP value of the second SSB sent by the first cell 102 based on the measurement configuration information of the first cell 102 to obtain the RSRP measurement result of the second SSB.
[0187] Step S2104: Terminal 101 determines that the RSRP measurement result of the second SSB is less than or equal to the first threshold.
[0188] Exemplarily, the terminal 101 compares the RSRP measurement result of the second SSB (i.e., the measured RSRP value of the second SSB) with the first threshold. For example, the terminal can determine whether the measured RSRP value of the second SSB is less than or equal to the first threshold. If the measured RSRP value of the second SSB is less than or equal to the first threshold, it can be considered that the RSRP measurement result of the second SSB is less than or equal to the first threshold.
[0189] 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 obtained by the terminal 101 from the first cell 102 includes the first threshold, and the first threshold may be used by the terminal 101 to determine whether to report the RSRP measurement report of the second SSB based on the RSRP measurement result of the second 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 102 based on the first threshold.
[0190] Step S2105: Terminal 101 determines to report the RSRP measurement report of the second SSB.
[0191] Exemplarily, the terminal 101 determines that the RSRP measurement result of the second SSB is less than or equal to the first threshold, then determines that it is necessary to report the RSRP measurement report of the second 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 second SSB 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 RSRP measurement report of the second SSB to request the second cell 103 to send the first SSB and / or SIB1. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the second 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 second SSB to instruct the terminal 101 to send the first information.
[0192] In some embodiments, the first information may be a wake-up signal (WUS), or the first information may include the wake-up signal.
[0193] Step S2106, the terminal 101 sends the RSRP measurement report of the second SSB to the first cell 102.
[0194] In some embodiments, the RSRP measurement report of the second 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 first information, where the first information is used to request the second cell 103 to send the first SSB and / or SIB1. Exemplarily, the RSRP measurement report of the second SSB may be used by the first cell 102 to determine whether it is necessary to trigger the terminal 101 to send the first information to request the second cell 103 to send the first SSB and / or SIB1.
[0195] In some embodiments, when the RSRP measurement result of the second SSB is less than or equal to the first threshold, the terminal 101 reports the RSRP measurement report of the second SSB to the first cell 102. Accordingly, the first cell 102 can receive the RSRP measurement report of the second SSB sent by the terminal 101. In some embodiments, the terminal 101 can periodically send the RSRP measurement report of the second SSB to the first cell 102. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the second 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 second SSB to instruct the terminal 101 to send the first information.
[0196] 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 second SSB, it can send the RSRP measurement report of the second SSB to the first cell 102. Alternatively, after the terminal 101 obtains the RSRP measurement result of the second SSB and determines that the RSRP measurement result of the second SSB is less than or equal to the first threshold, the RSRP measurement report of the second SSB is sent to the first cell 102.
[0197] Step S2107: The first cell 102 determines that indication information needs to be sent based on the RSRP measurement report of the second SSB.
[0198] Exemplarily, the first cell 102 may determine whether the terminal 101 needs to wake up the second cell through WUS to send SSB and / or SIB1 based on the RSRP measurement report of the second SSB reported by the terminal 101. For example, the first cell 102 determines that the RSRP of the second SSB is less than or equal to the first threshold based on the RSRP measurement report of the second SSB reported by the terminal 101, and may determine that the terminal 101 needs to wake up the second cell 103 through the first information. 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 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 SSB and / or SIB1.
[0199] Step S2108 , the first cell 102 sends indication information to the terminal 101 .
[0200] In some embodiments, the above-mentioned indication information is used to instruct the sending of the first information. Exemplarily, the above-mentioned indication information is used to instruct the terminal 101 to send the first information.
[0201] In some embodiments, the above-mentioned indication information is sent by the first cell 102 to the terminal 101, and accordingly, the terminal 101 receives the above-mentioned 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 second 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 the first information.
[0202] 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 the first information via RRC signaling / MAC CE / DCI.
[0203] Step S2109 , the terminal 101 sends first information to the second cell 103 .
[0204] In some embodiments, the above-mentioned first information is used to request the second cell 103 to send the first SSB and / or SIB1.
[0205] In some embodiments, the first information is 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 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 first SSB and / or SIB1.
[0206] In some embodiments, the terminal 101 obtains the configuration information of the second cell 103 through the second SIB information of the first cell. The terminal 101 sends the above-mentioned first information to the second cell 103 based on the configuration information of the second cell 103. Exemplarily, the terminal 101 in the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102 can obtain the configuration information of the second cell 103 through the second SIB of the first cell. Exemplarily, the terminal 101 enters the RRC connected state from the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, and can obtain the configuration information of the second cell 103 from the first cell 102 through dedicated RRC signaling. It should be noted that the first SIB information and the second SIB information in this document can be the same SIB information or different SIB information, and their contents can be the same or different. Exemplarily, the first SIB information and the second SIB information in this document can be understood as SIB1 of the first cell.
[0207] 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.
[0208] 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.
[0209] 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 first information associated with the second cell; information in the SIB1 of the second cell. In some embodiments, the configuration information related to the first information may include but is not limited to at least one of the following: a reamble index or sequence reserved for the first information; configuration information of a random access occasion (RACH Occasion, RO) resource, the RO resource being used to send the first information; the initial transmit power of the first information, or a parameter for calculating the initial transmit power. Exemplarily, the terminal 101 may send the first information to the second cell 103 based on the configuration information of the second cell 103 and / or the configuration information of the first information associated with the second cell.
[0210] 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.
[0211] It should be noted that, in some embodiments, the first cell 102 may be associated with one or more second cells 103. The configuration information 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 configuration information of the first information. Exemplarily, the one or more second cells may be associated with related configuration information of the same 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. 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 configuration information of the first information of each 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 first cell 102. The terminal may use the configuration information of the first information associated with second cell 1 to send the first information to second cell 1, and use the configuration information of the first information associated with second cell 2 to send the first information to second cell 2. The configuration information of the first information associated with second cell 1, second cell 2, and second cell 3 may be the same or different. Taking the example of the first information associated with at least some of the second cells being the same, terminal 101 may send the first information to at least some of the second cells based on the configuration information of at least some of the second cells and / or the configuration information of the same first information associated with at least some of the second cells. For example, taking the first cell 102 as being associated with second cell a and second cell b, the configuration information of the first information associated with second cell a and second cell b may be the same. Terminal 101 may send the first information to second cell a and second cell b, respectively, based on the configuration information of second cell a and second cell b and / or the configuration information of the same first information associated with second cell a and second cell b.
[0212] Taking the configuration information of at least part of the second cell being associated with different first information as an example, the terminal 101 can send the first information to the at least part of the second cell based on the configuration information of the at least part of the second cell and / or the configuration information of the first information associated with the at least part of the second cell. For example, the first cell 102 is associated with the second cell a and the second cell b, and the configuration information of the first information associated with the second cell a is different from the configuration information 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 information of the second cell a and / or the configuration information 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 information of the second cell b and / or the configuration information of the first information 2 associated with the second cell b.
[0213] 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.

[0215] In some embodiments, the second cell 103 sends a first SSB and / or SIB1 to the terminal 101, and accordingly, the terminal 101 receives the first SSB and / or SIB1 sent by the second cell 103. It should be noted that, in the embodiments of the present disclosure, the first SSB is a synchronization signal block sent by the second cell 103, and the second SSB is a synchronization signal block sent by the first cell 102.
[0216] Exemplarily, the terminal enters the RRC connected state from the RRC non-connected state (such as the RRC_IDLE / INACTIVE state) on the first cell 102, and the terminal 101 can request the second cell 103 to send the first SSB through the first information. In some embodiments, the first SSB is used by the terminal 101 to achieve synchronization with the second cell 103. Exemplarily, the second cell 103 sends the first SSB to the terminal 101 to facilitate the terminal 101 to search and identify the cell.

It should be noted that, in the embodiments of the present disclosure, the first SSB is a synchronization signal block sent by the second cell 103, and the second SSB is a synchronization signal block sent by the first cell 102.
[0241] Exemplarily, if the terminal 101 determines that the RSRP measurement result of the second SSB is less than or equal to the first threshold, the terminal 101 sends the first information to request the second cell 103 to send the first SSB and / or SIB1. That is, the terminal 101 sends the first information to the second cell 103. Accordingly, the second cell 103 can receive the first information sent by the terminal 101 to request the second cell 103 to send the first SSB and / or SIB1.
[0242] In some embodiments, the first information may be a wake-up signal (WUS), or the first information may include the wake-up signal.
[0243] In some embodiments, the terminal 101 obtains the configuration information of the second cell 103 through the second SIB information of the first cell. Based on the configuration information of the second cell 103, the terminal 101 sends the above-mentioned first information to the second cell 103. Exemplarily, the terminal 101 in the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102 can obtain the configuration information of the second cell 103 through the second SIB of the first cell.

[0275] In some embodiments, the terminal 101 may obtain the measurement configuration information from the first SIB information of the first cell 102. For example, the terminal 101 is in an RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, and the terminal 101 may obtain the measurement configuration information from the first SIB information of the first cell 102.
[0276] In some embodiments, the terminal 101 may obtain the measurement configuration information from the first cell 102 through dedicated RRC signaling.

[0277] Optionally, in some embodiments, step S2401 and step S2402 may be executed in an interchanged order. For example, step S2401 may be executed first and then step S2402. Alternatively, step S2402 may be executed first and then step S2401. In the case where step S2402 is executed first and then step S2401, the terminal 101 enters the RRC connected state from the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, so that the terminal 101 in the RRC connected state can obtain the above-mentioned measurement configuration information through the first SIB information of the first cell 102, or the terminal 101 in the RRC connected state can also obtain the above-mentioned measurement configuration information from the first cell 102 through dedicated RRC signaling. For example, the terminal 101 enters the RRC connected state from the RRC non-connected state (such as RRC_IDLE / INACTIVE state) on the first cell 102, so that the first cell 102 can send the above-mentioned measurement configuration information to the terminal 101 through dedicated RRC signaling. Correspondingly, the terminal 101 in the RRC connected state can obtain the above-mentioned measurement configuration information from the first cell 102 through dedicated RRC signaling.
[0278] In step S2403, the terminal 101 measures the RSRP of the second SSB sent by the first cell 102 based on the measurement configuration information, and obtains the RSRP measurement result of the second SSB.

[0284] Step S2406, the terminal 101 sends the RSRP measurement report of the second SSB to the first cell 102.
[0285] In some embodiments, the RSRP measurement report of the second SSB can be 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. Exemplarily, the RSRP measurement report of the second SSB can be used by the first cell 102 to determine whether to trigger the second cell 103 to wake up and send the first 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 second cell 103, and the second SSB is the synchronization signal block sent by the first cell 102.
[0286] In some embodiments, when the RSRP measurement result of the second SSB is less than or equal to the first threshold, the terminal 101 reports the RSRP measurement report of the second SSB to the first cell 102. Accordingly, the first cell 102 can receive the RSRP measurement report of the second SSB sent by the terminal 101. In some embodiments, the terminal 101 can periodically send the RSRP measurement report of the second SSB to the first cell 102. Exemplarily, the terminal 101 periodically reports the RSRP measurement report of the second 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 first SSB and / or SIB1 based on the RSRP measurement report of the second SSB.
[0287] Step S2407: The first cell 102 determines that it needs to request the second cell 103 to send the first SSB and / or SIB1 based on the RSRP measurement report of the second SSB.
[0288] Exemplarily, the first cell 102 may determine whether the terminal 101 needs to wake up the second cell 103 to send the first SSB and / or SIB1 based on the RSRP measurement report of the second SSB reported by the terminal 101. For example, the first cell 102 determines that the RSRP of the second SSB is less than or equal to the first threshold based on the RSRP measurement report of the second 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 first 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 first SSB and / or SIB1.
[0289] Step S2408 : The first cell 102 sends second information to the second cell 103 .
[0290] In some embodiments, the second information is sent by the first cell 102 to the second cell 103, and 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 RSRP measurement report of the second SSB, 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.
[0291] 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.
[0292] 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.
[0293] Step S2409, the second cell 103 sends the first SSB and / or SIB1.

[0450] It is worth noting that in the SSB / SIB1-less cell scenario, the terminal is within the coverage of the first cell (such as the anchor cell / normal cell). The SSB / SIB1-less cell without DRS is an invisible cell for the terminal. In order to solve the problem of when the terminal in the RRC_IDLE / INACTIVE state can trigger WUS to request the SSB / SIB1-less cell to send SSB and / or SIB1 in the SSB / SIB1-less cell scenario, a communication method is proposed. The details are as follows:
[0451] In some embodiments, the terminal enters the RRC connected state from the RRC_IDLE / INACTIVE state on the first cell, 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.
[0452] In some embodiments, the terminal enters the RRC connected state from the RRC_IDLE / INACTIVE state on the first cell. For example, the terminal in the RRC_IDLE state initiates an RRC connection establishment process to enter the RRC connected state, and the terminal in the RRC_INACTIVE state initiates an RRC connection recovery process to enter the RRC connected state. The terminal measures the SSB of the first cell, obtains the measured RSRP, and reports the measurement report to the network device. Exemplarily, the terminal determines that the measured RSRP value is less than or equal to a first threshold, and the terminal reports the measurement report to the network device. The first threshold is obtained by the terminal from the measurement configuration of the first cell. Exemplarily, the terminal periodically reports the measurement report to the network device.
[0453] 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. Other Xn signaling methods may be used, and this disclosure does not specifically limit them.
[0454] In some embodiments, the terminal enters the RRC connected state from the RRC_IDLE / INACTIVE state on the first cell, the terminal measures the SSB of the first cell, reports the measurement report to the network device, and the network device triggers the terminal to send a WUS.
[0455] In some embodiments, a terminal enters an RRC connected state from an RRC_IDLE / INACTIVE state on a first cell, measures the SSB of the 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.
[0456] 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 obtains the configuration information of the WUS from the SIB / dedicated RRC signaling of the first cell, for example, including at least one of the following: a preamble index or sequence reserved for WUS; configuration information of RO resources at the random access opportunity, the RO resources being used to send WUS; parameters for calculating the initial power for sending the WUS, or directly the initial power for sending the WUS.
[0458] In some embodiments, the terminal measures the SSB of the first cell. When the measured RSRP is less than a first threshold, the terminal sends a WUS to request the second cell to send the SSB and / or SIB1.
[0459] In some embodiments, the terminal is in an RRC_IDLE / INACTIVE state on a first cell, the terminal measures the SSB of the first cell, obtains a measured RSRP, the terminal determines that the measured RSRP is less than or equal to a first threshold, and the terminal sends a WUS requesting the second cell to send an SSB and / or SIB1. The first threshold is obtained by the terminal from a measurement configuration of the first cell, and the measurement configuration information may be obtained by the terminal from the SIB of the first cell, that is, the first threshold may be obtained by the terminal from the SIB of the first cell.
[0460] In some embodiments, the terminal obtains the configuration information of the WUS from the SIB of the first cell, for example, including at least one of the following: a preamble index or sequence reserved for WUS; configuration information of RO resources at the random access opportunity, the RO resources being used to send WUS; parameters for calculating the initial power for sending the WUS, or directly the initial power for sending the WUS.
[0461] In some embodiments, the terminal unconditionally sends a WUS to request the second cell to send an SSB and / or SIB1.
[0462] In some embodiments, the terminal is in the RRC_IDLE / INACTIVE state on the first cell, and the terminal determines that it needs to request the second cell to send SSB and / or SIB1, and the terminal sends WUS. Exemplarily, the terminal can determine whether it needs to request the second cell to send SSB and / or SIB1 based on implementation.
[0463] In some embodiments, the terminal obtains the configuration information of the WUS from the SIB of the first cell, for example, including at least one of the following: a preamble index or sequence reserved for WUS; configuration information of RO resources at the random access opportunity, the RO resources being used to send WUS; parameters for calculating the initial power for sending the WUS, or directly the initial power for sending the WUS.
