[0191] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0192] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 , a first network device 102 , and a second network device 103 .
[0193] In some embodiments, the terminal is in a cell of a second network device. Exemplarily, a network connection is established between the terminal and the second network device.
[0194] In some embodiments, the first network device and the second network device are adjacent network devices. Exemplarily, a cell of the first network device overlaps with a cell of the second network device.
[0195] In some embodiments, the network device may include at least one of an access network device and a core network device.
[0196] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

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.
[0199] 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.
[0200] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).
[0201] 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 provided by 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 provided by the embodiment of the present disclosure is also applicable to similar technical problems.
[0202] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0203] 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).
[0204] With people's pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the International Standards Organization has begun to develop the fifth generation mobile communication technology (5G, 5th Generation Mobile Communication Technology).
[0205] The main application scenarios for 5G are: enhanced mobile ultra-broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on enabling users to access multimedia content, services, and data, and demand for it is growing rapidly. Furthermore, 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 long module lifespans.
[0206] 5G base stations consume four times more energy than Long Term Evolution (LTE) base stations, so network energy conservation is an important means for operators to reduce the cost of operating 5G systems.
[0207] In some embodiments, a wake-up signal (WUS) is introduced to save energy for terminals in the Radio Resource Control (RRC) connected state (RRC_CONNECTED). A duration for sending the WUS signal is defined by an offset before the activation phase (on duration) of the UE C-DRX. During the WUS duration, the WUS signal, i.e., DCI 2-6, is sent and scrambled by the Power Saving Radio Network Temporary Indentifier (PS-RNTI) to indicate whether the terminal wakes up to monitor the Physical Downlink Control Channel (PDCCH) or wakes up during the next UE C-DRX onduration.
[0208] In some embodiments, a paging WUS is introduced to save energy for terminals in RRC idle or inactive states. This WUS, also known as a paging early indication (PEI), is sent sometime before a paging occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. PEI is downlink control information (DCI) 2-7, scrambled using the PEI-RNTI.
[0209] In some embodiments, in order to reduce network energy consumption, a network energy saving project is initiated. When the network enters energy-saving mode, namely Network Energy Saving (NES) mode, the cell periodically stops sending and / or receives at certain intervals, namely, the cell discontinuous receiving or transmitting (DTX / DRX). In related technologies, the following can be sent and received: Master Information Block (MIB), System Information Block (SIB), paging message (paging) and Random Access Channel (RACH). The four currently supported NES functions are as follows, and are separately specified in the standard: SSB-less Scell; cell DTX / DRX; Antenna port adaptation; PDSCH transmission power adaptation.
[0210] In some embodiments, a concept of a sleeping cell is proposed. The sleeping cell can be woken up by the UE as needed to provide services to the terminal.
[0211] In some embodiments, cells are always in an on state after network planning, actual network deployment, and network-side testing and verification. This fails to enable cells on demand, wasting resources and network operation power.
[0212] In some embodiments, triggering the activation of a sleeping cell on demand based on the UE sending an uplink (UL) WUS can maximize network energy savings while also increasing the flexibility of network deployment and operations. However, how the UE detects that it is approaching a sleeping cell or is already within the coverage of a sleeping cell and then sends an UL WUS to wake up the cell remains uncertain.
[0213] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0253] Contains a set of CSI-RS and SSB.
[0254] In some embodiments, the DL signal set is used by a terminal to determine whether the terminal is close to or already within the signal coverage of a first cell. Exemplarily, this determination can be based on the radio transmission quality value of a reference signal in the DL signal set. If the radio transmission quality value is greater than a certain threshold, it can be determined that the terminal is close to or already within the signal coverage of the first cell.
[0255] In some embodiments, the first configuration information is configuration information of a discovery reference signal DRS of the first cell.

The threshold value may be configured on a per-beam basis (i.e., one threshold value per beam) or on a per-beam group basis (i.e., one threshold value per beam).
[0264] Exemplarily, the beam may be a CSI-RS or SSB beam.
[0265] For example, the measurement quantity for the target reference signal may be Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR). Here, the measurement quantity may be network-configured.
[0266] Exemplarily, this threshold value can also be configured based on each CSI-RS (per CSI-RS, one threshold value corresponds to one CSI-RS), each CSI-RS group (CSI-RS group, multiple CSI-RSs in the group correspond to one threshold value), each SSB index (per SSB index, one SSB corresponds to one threshold value) or each SSB index group (SSB index group, multiple SSBs in the group correspond to one threshold value).
[0267] Exemplarily, the threshold value may also be configured based on the CSI-RS and SSB index group. That is, the CSI-RS and SSB index may jointly correspond to one threshold value.
[0268] In some embodiments, the evaluated measurement value may be determined on a per-beam basis, for example, on a per-CSI-RS or per-SSB basis.
[0269] In some embodiments, the evaluated measurement value may also be determined based on a linear average of at least one beam, for example, based on a linear average of measurement values of a group of CSI-RSs or a group of SSBs.
[0270] In some embodiments, the first configuration information includes indication information determining, based on DRS measurement, that the terminal is close to or within the coverage of the first cell.

[0443] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through three exemplary embodiments:
[0444] Example 1:
[0445] In some embodiments, a technical solution 1 is provided: determining whether the cell is close to a sleeping cell (corresponding to the first cell) based on pre-configured CSI-RS detection and measurement.
[0446] In some embodiments, the sleeping cell may have a DL discovery signal, ie, a DRS (Discovery Reference Signal), or may not have a DRS.
[0447] In some embodiments, a cell in a normal operation state broadcasts configuration information related to a sleeping cell. The sleeping cell and the cell in a normal operation state (corresponding to the second cell) have overlapping coverage or adjacent coverage, that is, the sleeping cell and the cell in a normal operation state are in a neighboring cell relationship. The configuration information related to the sleeping cell (corresponding to the first configuration information) can be configured in the SIB1 of the normal operation cell or in a newly defined SIB.
[0448] In some embodiments, the configuration information related to the sleeping cell includes at least one of the following:
[0449] Identification information of the sleeping cell, such as at least one of: PCI, cell identity, RNAC, TAC, etc.;
[0450] The beam transmission method of the sleeping cell, such as the period, maximum number of beams, and the directions in which beams are sent. This configuration is used not only for SSB and SIB1, but also for DRS if available;
[0451] Frequency information of the sleeping cell, such as frequency layer, SSB frequency, UL WUS frequency, etc.
[0452] The slice list supported by the Sleeping cell;
[0453] Public configuration information of the sleeping cell, such as RACH-related configuration information;
[0454] UL WUS configuration information, such as the preamble index or sequence reserved for UL WUS, and / or the configuration information of the random access channel opportunity RO resource. The RO resource is used to send the WUS. Parameters used to calculate the initial power for sending the UL WUS, or directly the initial power for sending the UL WUS;
[0455] All or part of the configuration information of the SSB and / or SIB1 of the Sleeping cell;
[0456] DL timing deviation between the sleeping cell and the currently operating cell;
[0457] A DL signal set indicating the coverage of a sleeping cell. The DL signal set includes a CSI-RS set, an SSB set, or a set containing both CSI-RS and SSB. The DL signal set is used by the UE to assess whether the UE is close to or already within the coverage of a sleeping cell.
[0458] Sleeping cell DRS configuration, such as DRS period, frequency domain resources, sequence generation configuration, etc. DRS measurement based on whether the threshold is close to the sleeping cell, measurement quantity configuration, etc. (Similar to the following, but based on DRS measurement);
[0459] Condition configuration information used to evaluate whether the UE is close to a sleeping cell or is already within the coverage of a sleeping cell, such as whether the measured target signal is greater than or less than the threshold configured on the network side. Whether it is greater than or less than can be configured per beam (this beam can be CSI-RS or SSB) or per beam group. The measurement quantity is RSRP or RSRQ or SINR, depending on the network side configuration. This threshold configuration can be per CSI-RS or CSI-RS group, or per SSB index, or SSB index group, or CSI-RS and SSB index group. The measurement value used for evaluation can be per beam, that is, per CSI-RS or SSB. It can be a linear average based on at least one beam, such as a group of CSI-RS or a group of SSB;
[0460] If a DRS exists in the sleeping cell, it can be determined based on the DRS measurement whether it is close to the sleeping cell or is already within the coverage of the sleeping cell;
[0461] In some embodiments, if it is a sleeping cell with DRS, the measurement and evaluation of the above-mentioned DL signal set can be used to indicate whether to start the detection and measurement of DRS.
[0462] In some embodiments, the terminal determines whether it is near a sleeping cell based on the above configuration. If so, it can send an UL WUS to wake up the sleeping cell as needed. For RRC_CONNECTED UEs, to send UL WUS, the network configures a gap for sending UL WUS. The gap can be periodic or a one-shot gap. The gap can be an event-triggered gap or a UE-requested gap.
[0463] In some embodiments, after the sleeping cell wakes up, it sends SSB, SIB1, paging if any, and receives the random access process normally.
[0464] Example 2:
[0465] In some embodiments, a technical solution 2 is provided: a UL WUS without a sleeping cell sends a wake-up request signal to a normally operating cell.
[0466] In some embodiments, a cell in a normal operating state broadcasts configuration information related to a sleeping cell. The sleeping cell and the cell in a normal operating state have overlapping coverage or adjacent coverage, that is, the sleeping cell and the cell in a normal operating state are in a neighboring cell relationship. The configuration information related to the sleeping cell can be configured in the SIB1 of the normal operating cell or in a newly defined SIB.
[0467] In some embodiments, the configuration information related to the sleeping cell includes at least one of the following:
[0468] Identification information of the sleeping cell, such as at least one of: PCI, cell identity, RNAC, TAC, etc.;
[0469] The beam transmission method of the sleeping cell, such as the period, maximum number of beams, and the directions in which beams are sent. This configuration is used not only for SSB and SIB1, but also for DRS if available;
[0470] Frequency information of the sleeping cell, such as frequency layer, SSB frequency, UL WUS frequency, etc.
[0471] The slice list supported by the Sleeping cell;
[0472] Public configuration information of the sleeping cell, such as RACH-related configuration information;
[0473] Preamble resources and / or RO resources reserved in the currently operating cell for the UE to send wake-up signals to the currently operating cell;
[0474] All or part of the configuration information of the SSB and / or SIB1 of the Sleeping cell;
[0475] DL timing deviation between the sleeping cell and the currently operating cell;
[0476] A DL signal set indicating the coverage of a sleeping cell. The DL signal set includes a CSI-RS set, an SSB set, or a set containing both CSI-RS and SSB. The DL signal set is used by the UE to assess whether the UE is close to or already within the coverage of a sleeping cell.
[0477] Sleeping cell DRS configuration, such as DRS period, frequency domain resources, sequence generation configuration, etc. DRS measurement based on whether the threshold is close to the sleeping cell, measurement quantity configuration, etc. (Similar to the following, but based on DRS measurement);
[0478] Condition configuration information used to evaluate whether the UE is close to a sleeping cell or is already within the coverage of a sleeping cell, such as whether the measured target signal is greater than or less than the threshold configured on the network side. Whether it is greater than or less than can be configured per beam (this beam can be CSI-RS or SSB) or per beam group. The measurement quantity is RSRP or RSRQ or SINR, depending on the network side configuration. This threshold configuration can be per CSI-RS or CSI-RS group, or per SSB index, or SSB index group, or CSI-RS and SSB index group. The measurement value used for evaluation can be per beam, that is, per CSI-RS or SSB. It can be a linear average based on at least one beam, such as a group of CSI-RS or a group of SSB;
[0479] If a DRS exists in the sleeping cell, it can be determined based on the DRS measurement whether it is close to the sleeping cell or is already within the coverage of the sleeping cell;
[0480] In some embodiments, if it is a sleeping cell with DRS, the measurement and evaluation of the above-mentioned DL signal set can be used to indicate whether to start the detection and measurement of DRS.
[0481] In some embodiments, the terminal determines whether it is close to a sleeping cell based on the above configuration. If so, it can send a request to wake up the sleeping cell to the normally operating cell as needed:
[0482] In some embodiments, for RRC_IDLE / INACTIVE UE, the UE sends a reserved preamble to the normal operation cell. If a RAR containing the preamble ID is received, it is considered that a request command is received, and the normal operation cell notifies the sleeping cell to wake up.
[0483] In some embodiments, for RRC_IDLE / INACTIVE UE, the UE sends a random access process to the normally operating cell, and requests to wake up the target sleeping cell through an RRC message (the RRC message may be an RRCSystemInfoRequest or a newly defined RRC message). The RRC message carries the target cell requested to be woken up. If the conflict is successfully resolved, it is considered that the request command has been received, and the normally operating cell notifies the sleeping cell to wake up.
[0484] In some embodiments, for an RRC_CONNECTED UE, an RRC dedicated signaling is sent to a normally operating cell, where the RRC dedicated signaling carries a target cell requested to be woken up. After receiving the command, the normally operating cell notifies the sleeping cell to wake up.
[0485] In some embodiments, after the sleeping cell wakes up, it sends SSB, SIB1, paging if any, and receives the random access process normally.
[0486] Example 3:
[0487] In some embodiments, a technical solution 3 is provided: based on the change of the sleeping cell state, the system broadcast of the normally operating cell is changed.
[0488] In some embodiments, when the sleeping cell is in the awake state, the broadcast determines whether the relevant configuration information in the normally operating cell needs to be reconfigured, and whether the terminal needs to be notified in time to receive the changed configuration if a change is required.
[0489] In some embodiments, when a sleeping cell is in the awake state and wakes up from the sleeping state, it notifies the normal operating cell of the state change. At this time, the normal operating cell removes the configuration related to the sleeping cell. However, it does not notify the terminals in the local cell of the configuration change, that is, it does not send a paging message.
[0490] In some embodiments, when a sleeping cell is awakened from the sleeping state, it notifies the normal operating cell of the state change. The normal operating cell then removes the configuration related to the sleeping cell and notifies the terminals in the local cell of the configuration change by sending a paging message. In this case, the system broadcast information change indication in the paging DCI is reused, or a new indication message is defined in the paging DCI specifically to indicate the change of the sleeping cell-related configuration.
[0491] In some embodiments, when a sleeping cell is in an awake state and wakes up from the sleeping state, the normally operating cell is not notified of the state change, and the normally operating cell does not remove the configuration of the sleeping cell.
