The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0137] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0138] In some embodiments, a core network device may be a single device, including one or more network elements, or it may be multiple devices or a group of devices, each including all or part of one or more network elements.

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0141] The following embodiments of this disclosure can be applied to the communication system or some of the subjects shown in FIG1A, but are not limited thereto. The subjects shown in FIG1A are illustrative. The communication system may include all or some of the subjects in FIG1A, or may include other subjects other than those in FIG1A. The number and form of each subject are arbitrary. The connection relationship between the subjects is illustrative. The subjects may not be connected to each other or may be connected in any way.

[0142] The embodiments disclosed herein can be applied to satellite communications, 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 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0143] In some embodiments, the network system can locate terminals through a paging mechanism. When the network has downlink data and signaling that needs to be sent, the network system can locate terminals through the paging mechanism. By sending a paging message, the terminal initiates a Radio Resource Control (RRC) connection establishment or connection restoration process, enabling the network to contact terminals in the RRC_IDLE (idle state) and RRC_INACTIVE (inactive state) states. In addition, paging can also notify terminals in the RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED (connected state) states to receive system message updates, as well as warning information from the Earthquake and Tsunami Warning System (ETWS) and the Commercial Mobile Alert System (CMAS, or WEA, Wireless Emergency Alerts).

[0144] In some embodiments, a terminal needs to perform at least three operations to obtain a paging message:

[0145] (1) Listen to the synchronization signal block (SSB) and / or TRS to complete time and frequency synchronization.

[0146] (2) Listen for paging timing (PO, or paging control information, etc.) to obtain information such as the time, frequency and location of paging messages.

[0147] (3) Listen to the P-PDSCH corresponding to the paging message to obtain the paging message.

[0148] In some embodiments, the PO depends on the paging type (e.g., a terminal in the core network paging RRC_IDLE state / a terminal in the access network paging RRC_INACTIVE state). The matching identifier of the PO can be divided into System Temporary Mobile Subscriber Identity (S-TMSI) and Inactive-Radio Network Temporary Identifier (I-RNTI).

[0149] In some embodiments, the PO resource determination method is: i_PO (used to further refine to one or more specific POs within a paging frame) / i_SG (used to identify a paging subframe or paging slot within a frame)

[0150] In some embodiments, to address the additional power consumption caused by false alarms on the terminal side, PO listening resources need to be properly grouped, such as according to the following grouping:

[0151] (1) P-RNTI (reduce P-PDSCH demodulation listening).

[0152] (2) TF resources (reduce P-PDSCH demodulation eavesdropping).

[0153] (3) P-DCI grouping (reducing P-PDSCH demodulation eavesdropping).

[0154] (4) Grouping based on PEI.

[0155] Furthermore, antenna port-based grouping can be added, especially in the time-frequency resource direction. Adding antenna ports will further reduce overhead. The more P-PDSCH groups there are, the more significant the energy-saving gain will be.

[0156] In some embodiments, the PEI is typically sent to the terminal as an additional indication signal before the paging opportunity. It can be transmitted via a specific physical channel (such as PDCCH) and encoded using a specific Downlink Control Information (DCI) format. When the network needs to send a paging message to the terminal, it sends a signal containing the PEI before the corresponding paging opportunity. Upon receiving the PEI, the terminal determines whether to continue listening for the next paging opportunity (PO) based on the indication information within it.

[0157] In some embodiments, PEI is enhanced for paging:

[0158] (1) There are multiple candidate PEI bearers, including primary / secondary synchronization signal (PSS / SSS), tracking reference signal (TRS), channel state information reference signal (CSI-RS), and DCI.

[0159] (2) There are two ways to indicate the candidate PEI: implicit / explicit.

[0160] (3) PEI can indicate whether TRS resources are available, where the TRS configuration includes information to a certain SSB from the Quasi-Co-located (QCL), namely the SSB index and / or SSB transport port.

[0161] (4) PEI to PF mapping: up to 2 PFs. For example, a PEI can be mapped to up to two paging frames. This means that the network can use the PEI to indicate to the terminal which PF(s) to listen for paging messages. Furthermore, considering the antenna port domain, more resources can be reused on 2 PFs.

[0162] Per Corest beam association with SSB refers to how a CORESET is associated with a specific beam. In the millimeter-wave band, beamforming technology is widely used to improve signal quality and coverage due to the propagation characteristics of high-frequency signals. By associating a CORESET with a specific SSB beam, the network can more accurately guide terminals on which beam to listen for control information, thereby improving communication efficiency and performance.

[0163] Port-specific coreset 0 (CORESET 0) allows for specific configurations based on different antenna ports. To support massive MIMO (Multiple-Input Multiple-Output) technology and beamforming, multiple antenna ports may be used. CORESET 0 can be optimized for different ports to ensure efficient transmission of the control channel.

[0164] In some embodiments, the association between the Coreset 0 beam and the SSB beam antenna port is used in Search space multiplexing mode 1, i.e., SSB and Coreset time-division multiplexing scenario.

[0165] Furthermore, considering the antenna port domain, SS0 could potentially be used for PEI. As the number of packets increases further, PEI can be distinguished by antenna port, and multi-layer transmission can be employed as the number of bits increases. For example, to support more packets and more complex information transmission, the network can adopt a port-distinguished approach, where different antenna ports carry different PEI information.

[0166] In some embodiments, high-frequency bands and large-scale antenna arrays are introduced to provide higher spectral efficiency. Large-scale antennas can provide greater beamforming gain, effectively compensating for transmission losses caused by high frequencies, while the array elements possess spatially non-stationary characteristics. For a given antenna array (whose aperture is denoted as D), its electromagnetic (EM) field can be divided into near-field and far-field, as shown in Figure 1B. The boundary between the near-field and far-field is... This is known as the Rayleigh distance. The size of the near-field range depends on the antenna aperture (D) and the wavelength (λ).

[0167] In some embodiments, for a terminal in the far field, the electromagnetic waves arriving at the terminal from its different antenna ports or elements are plane waves, and the beam targeting the terminal is a two-dimensional (2D) directional beam pointing towards the target terminal. For any path in multipath propagation, the time and phase of arrival at the terminal's receiving antenna array are equally spaced, as shown in Figure 1C(a), i.e., the general assumption of parallel electromagnetic waves. If the terminal is in the near field, then the electromagnetic waves received by the terminal are spherical waves, and the beam targeting the terminal is a three-dimensional (3D) beam surrounding the target terminal. For any path in multipath propagation, the time and phase of arrival at the terminal's receiving antenna array will no longer be equally spaced, as shown in Figure 1C(b). When the terminal is in the near field, as described above, for any path in multipath propagation, the time and phase of arrival at the terminal's receiving antenna array are no longer equally spaced.

[0168] It should be noted that, assuming the cell size inherits from the typical cell size in a given scenario (e.g., a spacing of 200m / 500m / 1732m), both near-field and far-field terminals will exist within a single cell. Paging, as a fundamental process of network-terminal interaction, requires ensuring smooth message reception for both near-field and far-field terminals, while maximizing the use of near-field characteristics to meet the energy-saving transmission requirements of near-field users. Therefore, for both near-field and far-field terminals, the technical challenge of how they can monitor paging-related information needs to be addressed.

[0169] To address this, this disclosure proposes a communication scheme that distinguishes between near-field and far-field terminals based on antenna port information. The scheme allows for the reception of corresponding first information based on specific antenna port information. This first information can be used to assist the terminal in receiving paging messages, thus solving the technical problem of how these terminals can monitor paging-related information. This improves the efficiency and accuracy of receiving paging messages and provides energy-saving benefits to the terminal.

[0170] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes the following steps:

[0171] In step S201, the network device sends the first information to the terminal based on the antenna port information.

[0172] In some embodiments, the terminal receives first information sent by the network device based on antenna port information.

[0173] In some embodiments, antenna port information may include at least one of the following:

[0174] Antenna port number; antenna port index; antenna port group number; antenna port group index, etc.

[0175] In some embodiments, the terminal may include a near-field terminal and / or a far-field terminal. To more effectively send information to these terminals at different distances, the network device optimizes the information transmission method based on antenna port information. The antenna port information may include the antenna port number, port index, packet number, packet index, etc. Different near-field and far-field terminals can be distinguished based on this different antenna port information, and thus these terminals can receive their respective corresponding first information according to this different antenna port information.

[0176] In some embodiments, the antenna port information can be used by a near-field terminal to listen to the first information.

[0177] In some embodiments, the antenna port information can be ignored when the far-field terminal is listening to the first information, such as using fixed antenna port information to listen to the first information.

[0178] In some embodiments, the first information may be paging-related information, which can be used to assist the terminal in receiving paging messages. In this embodiment, the terminal can receive the first information sent by the network device based on antenna port information. This first information can be used to assist the terminal in receiving paging messages, thereby solving the technical problem of how to monitor paging-related information, improving the efficiency and accuracy of the terminal in receiving paging messages, and resulting in energy-saving effects for the terminal.

[0179] In some embodiments, the first information may be auxiliary information that can be generated by a network device and sent to the terminal, with the purpose of helping the terminal to receive upcoming paging messages more effectively.

[0180] In some embodiments, when a network device is ready to send a paging message to a terminal, it first sends initial information based on antenna port information. This step helps the terminal adjust its receiving parameters to receive the upcoming paging message more efficiently. This ensures stable communication between the terminal and the network, improves overall system performance, and enhances the user experience.

[0181] In some embodiments, the first information includes at least one of the following A1 to E1:

[0182] A1. Power-saving related signals. In some examples, power-saving related signals may include Paging Early Indication (PEI), and / or Wake Up Signal (WUS), and / or other signals related to terminal power saving.

[0183] In some examples, PEI (Pre-Paging Indication) is a type of indication information sent by the network to the terminal in advance during the paging process. It informs the terminal of upcoming paging messages, allowing it to prepare for receiving them and facilitating more efficient subsequent communication. Energy conservation is crucial for terminals, especially mobile terminals with limited battery power. Without PEI, terminals need to continuously monitor the network for paging messages, consuming significant power. PEI allows the terminal to enter a sleep state during periods when no paging messages are expected, waking only before a potential paging message arrives, thus greatly reducing power consumption and extending battery life. By sending paging-related indications to the terminal in advance, it can adjust its receiving parameters and configurations to prepare for receiving paging messages, reducing paging message reception and processing time, improving paging success rate and efficiency, and ultimately enhancing the overall network communication performance.

[0184] In some embodiments, power-saving related signals can be carried by a first sequence, such as the PE (Power Provider) signal. In some examples, the first sequence can be used to assist downlink synchronization. For example, the first sequence can be a sequence of synchronization signals, which can be used to assist the terminal in performing downlink synchronization. In some examples, the first sequence can be used to distinguish different PO (Positioning Object) packets, for example, different ports of the first sequence correspond to different PO packets.

[0185] In some embodiments, different near-field terminals and far-field terminals can be distinguished based on antenna port information. The network device can then send PEI based on the antenna port information. Correspondingly, the terminal can receive the PEI sent by the network device based on the antenna port information and determine whether it needs to wake up to listen to PO in the next Discontinuous Reception (DRX) cycle, and whether it needs to listen to SSB / TRS before listening to PO, etc.

[0186] In some embodiments, PEI can be an ultra-low power wake-up signal, using amplitude shift keying (ASK) / frequency shift keying (FSK) / orthogonal frequency division multiplexing (OFDM) modulation.

[0187] B1. Paging Timing (PO). In some examples, the network sends paging messages according to predetermined POs, and the terminal listens on the paging channel at the corresponding PO to ensure that both parties can exchange information at the correct time, avoiding confusion in the sending and receiving of paging messages. Explicit paging timing eliminates the need for the terminal to continuously listen to the network; it only needs to wake up and listen on the paging channel when a PO arrives. This significantly reduces the terminal's power consumption and extends battery life.

[0188] In some embodiments, the time-frequency resources of the PO can be determined by the terminal's identifier or packet information sent by the network device. In some examples, the packet information may include at least one of the following:

[0189] Group identifier; number of groups; number of paging frames; actual SSB transmitted; port information for transmitting the first message.

[0190] For example, the time and frequency resources of a PO can be determined through the terminal's identifier or packet information issued by the core network / access network, such as group number, number of groups, number of paging frames, and the actual transmitted SSB (such as implicit packet information corresponding to the actual transmitted SSB), port information for transmitting the first information, etc.

[0191] In some embodiments, different near-field terminals and far-field terminals can be distinguished based on antenna port information, and then the terminal can receive PO based on the antenna port information.

[0192] C1. The Physical Downlink Shared Channel (PDSCH) corresponding to the paging message; that is, the paging message is carried through the PDSCH, and the terminal can obtain the paging message on the PDSCH. The modulation and coding scheme, time and frequency resource location and size, and indication of the presence of a tracking reference signal of the paging message can be found in the paging control information.

[0193] In some embodiments, different near-field terminals and far-field terminals can be distinguished based on antenna port information, and then the terminal can obtain paging messages on the PDSCH based on the antenna port information.

[0194] D1. Tracking Reference Signal (TRS): During paging, the terminal needs to accurately understand the state of the wireless channel to correctly receive paging messages. The TRS provides a reference signal, which the terminal can receive and analyze to measure the gain, delay, Doppler shift, and other characteristics of the wireless channel at different times, thereby obtaining accurate channel information. The paging process requires the terminal to maintain time synchronization with the network to ensure that the terminal can listen for paging messages at the correct time. The TRS has a specific periodicity and regularity in time. By receiving the TRS, the terminal can calibrate its own time with the network time, ensuring that the terminal's clock is synchronized with the network clock and avoiding missing paging messages due to time discrepancies.

[0195] In some embodiments, different near-field terminals and far-field terminals can be distinguished based on antenna port information, and the terminal can then monitor TRS based on the antenna port information.

[0196] E1. Synchronization Signal Block (SSB). During paging, the terminal needs to maintain time and frequency synchronization with the network. The SSB provides the necessary synchronization signals (PSS and SSS) to enable the terminal to correctly decode control information on the Physical Downlink Control Channel (PDCCH) and the actual paging message on the PDSCH.

[0197] In some embodiments, different near-field terminals and far-field terminals can be distinguished based on antenna port information, and the terminal can then listen to the SSB based on the antenna port information.

[0198] In some embodiments, antenna port information may be explicitly carried by at least one of A2 to E2 below, and the network device may then indicate the antenna port information to the terminal by at least one of A2 to E2 below.

[0199] A2, SSB: For example, network devices can use SSB to indicate antenna port information to the terminal.

[0200] B2, SIB, such as SIB1 / SIB19, etc., such as network devices can indicate antenna port information to the terminal through SIB1 / SIB19.

[0201] C2. Bit indication of the first information, such as network devices indicating antenna port information to the terminal through the bit information of paging related information, different bits can indicate their respective antenna port information.

[0202] The configuration information of D2 and TRS, such as antenna port information, can be explicitly carried through the configuration information of TRS.

[0203] E2. Network device configuration, such as indicating antenna port information to the terminal in the configuration of the access network or core network.

[0204] In some examples, antenna port information explicitly carried via SSB (A2) may include being carried via at least one of the following A3 through G3:

[0205] A3, PBCH, such as antenna port information, are explicitly carried in PBCH.

[0206] In some examples, the SSB contains the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH), while the Primary Information Block (MIB) can be carried by the PBCH, and antenna port information can also be carried by the MIB.

[0207] B3. The root sequence group number used to generate the synchronization signal sequence, such as the antenna port information, is explicitly carried in the root sequence group number.

[0208] C3. The sequence number used to generate the synchronization signal sequence, such as the antenna port information, is explicitly carried in this sequence number.

[0209] D3. The scrambling information used to generate the synchronization signal sequence, such as antenna port information, is explicitly carried in the scrambling information.

[0210] E3. The root sequence group number used by the DMRS to generate the PBCH, such as the antenna port information, is explicitly carried in this root sequence group number.

[0211] F3. The sequence number used by the DMRS to generate the PBCH, such as the antenna port information, is explicitly carried in this sequence number.

[0212] G3. The scrambling information used by the DMRS to generate the PBCH, such as antenna port information, is explicitly carried in this scrambling information.

[0213] In some embodiments, antenna port information can be determined by a bit field indicating the availability of a tracking reference signal. For example, if the antenna port information is determined by a bit field indication in control information, this control information also carries bit field indication information indicating the availability of the tracking reference signal. In this way, the antenna port information can be accurately indicated to the terminal. For instance, the terminal obtains the available TRS and the antenna port information available for that TRS by using the bit field indicating TRS availability via PEI, and then determines the antenna port information.

[0214] In some embodiments, antenna port information can be determined through the mapping relationship between SSB and first information. For example, the terminal can implicitly determine the antenna port information through the mapping relationship between SSB and PEI.

[0215] In some embodiments, the mapping relationship between SSB and first information depends on a certain mapping ratio and mapping order. In some examples, this mapping order may include a sorting criterion for SSB and first information, and SSB and first information may be encoded according to one of the following sorting criteria:

[0216] The first priority is frequency domain resources; the second priority is time domain resources; and the third priority is code domain resources (such as SSB port resources, DMRS of paging messages, or receive port resources, etc.). These can be encoded according to this ordering criterion.

[0217] First priority code domain resources (such as SSB port resources, DMRS of paging messages, or receive port resources, etc.); second priority time domain resources; third priority frequency domain resources, which can be encoded according to this ordering criterion.

[0218] The first priority is the code domain resources (such as SSB port resources, DMRS of paging messages, or receive port resources, etc.); the second priority is the frequency domain resources; and the third priority is the time domain resources. These can be encoded according to this ordering criterion.

[0219] In some examples, the mapping ratio involved in this mapping relationship can be obtained through mathematical operations (such as multiplication or division) on the following types of information over a certain correlation period:

[0220] SSB port resources; SSB time domain resources; SSB frequency domain resources; time domain resources where the paging message is located; frequency domain resources where the paging message is located; code domain resources where the paging message is located, such as the synchronization sequence root sequence group number, sequence number, and DMRS port number.

[0221] In some embodiments, antenna port information can be determined through the mapping relationship between TRS and first information. For example, the terminal can implicitly determine the antenna port information through the mapping relationship between TRS and PEI.

[0222] In some embodiments, the mapping relationship between TRS and the first information depends on a certain mapping ratio and mapping order. In some examples, this mapping order may include a sorting criterion for TRS and the first information, and TRS and the first information may be encoded according to one of the following sorting criteria:

[0223] First priority frequency domain resources; second priority time domain resources; third priority code domain resources (such as TRS port resources, DMRS of paging messages, or receive port resources, etc.), which can be encoded according to this sorting criterion.

[0224] First priority code domain resources (such as TRS port resources, DMRS or receive port resources for paging messages, etc.); second priority time domain resources; third priority frequency domain resources, which can be encoded according to this sorting criterion.

[0225] First priority code domain resources (such as TRS port resources, DMRS or receive port resources for paging messages, etc.); second priority frequency domain resources; third priority time domain resources, which can be encoded according to this ordering criterion.

[0226] In some examples, the mapping ratio involved in this mapping relationship can be obtained through mathematical operations (such as multiplication or division) on the following types of information over a certain correlation period:

[0227] TRS port resources; TRS time domain resources; TRS frequency domain resources; time domain resources where the paging message is located; frequency domain resources where the paging message is located; code domain resources where the paging message is located, such as the synchronization sequence root sequence group number, sequence number, and number of DMRS ports.

[0228] In some embodiments, the terminal can obtain information related to the energy of a certain reference signal configured by the system, such as the Reference Signal Receiving Power (RSRP) energy threshold, through broadcast messages from the network. The terminal listens to the Synchronization Signal Transport Block (SSB) according to the time-frequency resource location specified in the broadcast message or protocol. When it detects that the energy consumption is higher than the RSRP energy threshold, the terminal obtains information about the antenna port from the PBCH of this SSB and uses this port-related information, for example, to receive PEI based on the antenna port information.

[0229] In some embodiments, after the terminal receives PEI based on antenna port information, if it confirms that it will continue to receive PO, PDSCH corresponding to paging messages, etc., it can still listen based on the information related to the antenna port.

[0230] In some embodiments, the synchronization resource block information configuration may include at least two sets:

[0231] The first approach: For near-field terminals, more than one port can be used for transmission.

[0232] The second set: For far-field terminals, only one port number is needed for transmission.

[0233] In some embodiments, the terminal reports near-field related metrics to the network, which may be information based on the measurement of synchronization signal energy (RSRP / RSRQ).

[0234] In some embodiments, antenna port information can also be carried by the PO, specifically in either explicit or implicit ways. In some examples, explicit carrying can be achieved by directly carrying the port number information in the PO. In some examples, implicit carrying can be achieved by carrying the synchronization signal transmission block information corresponding to the antenna port information in the PO. For example, the corresponding antenna port information can be determined based on the synchronization signal transmission block index, where the synchronization transmission block index includes both the synchronization transmission block analog beam direction information and the transmission port information.

[0235] This disclosure proposes a communication scheme that distinguishes between near-field and far-field terminals based on antenna port information. The scheme allows for the reception of corresponding first information based on specific antenna port information. This first information can be used to assist the terminal in receiving paging messages, solving the technical problem of how these terminals can monitor paging-related information. This improves the efficiency and accuracy of receiving paging messages and leads to energy-saving effects for the terminal.

[0236] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the method includes:

[0237] Step S301: The terminal receives the paging message based on the first information sent by the network device.

[0238] In some embodiments, the terminal receives first information sent by the network device based on antenna port information. The first information may be paging-related information and may be used to assist the terminal in receiving paging messages.

[0239] In some embodiments, the first information includes at least one of the following A1 to E1:

[0240] A1. Power saving related signals.

[0241] B1, PO.

[0242] C1, the PDSCH corresponding to the paging message.

[0243] D1, TRS.

[0244] E1, SSB.

[0245] The above information can effectively help the terminal receive paging messages sent by network devices.

[0246] Optionally, other possible implementations of step 301 can be found in Figure 2, and will not be elaborated here.

[0247] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0248] This disclosure proposes a communication scheme that distinguishes between near-field and far-field terminals based on antenna port information. The scheme allows for the reception of corresponding first information based on specific antenna port information. This first information can be used to assist the terminal in receiving paging messages, solving the technical problem of how these terminals can monitor paging-related information. This improves the efficiency and accuracy of receiving paging messages and leads to energy-saving effects for the terminal.

[0249] The following are some exemplary specific solutions proposed in the embodiments of this disclosure:

[0250] In some embodiments, the terminal receives paging-related information based on certain port information.

[0251] In some examples, the paging-related information includes: first paging information, second paging information, and third paging information.

[0252] In some examples, the first paging message can be a control message, or a sequence. This sequence can be used to carry the first paging message, or it can assist in the downlink synchronization process, etc.

[0253] In some examples, the second paging information may be paging-related control information. The time-frequency resources of the second paging information are determined by the UE ID or packet information issued by the core network / access network, such as group number, number of groups, number of paging frames, and actual transmitted synchronization signal blocks (SSBs).

[0254] In some examples, the third paging information may be paging-related data information, and the modulation and coding scheme, time-frequency resource location and size, and indication of the presence of a tracking reference signal in the second paging information may be present in the third paging information.

[0255] In some embodiments, port information can be displayed in the configuration information of receiving Synchronous Transmission Block (SSB), System Broadcast Message (SIB), Paging Related Message, or Tracking Reference Signal, or it can be implicitly determined through the mapping relationship between Synchronous Transmission Block (SSB) / TRS and Paging Related Information.

[0256] In some embodiments, the display carrier described above includes at least one carrier on:

[0257] -In the Physical Broadcast Channel (PBCH).

[0258] - The sequence of the synchronization signal (PSS / SSS) is generated from the root sequence group number, sequence number, or scrambling code information.

[0259] -PBCH demodulation reference signal (DMRS) generation root sequence group number or sequence number or scrambling information.

[0260] -In the bit indication of the paging-related message.

[0261] - In the configuration information for tracking the reference signal.

[0262] - In System Broadcast Messages (SIBs), such as SIB1 / SIB19, etc.

[0263] - In the configuration of the access network.

[0264] - In the core network configuration.

[0265] In some embodiments, the display bearer described above includes at least port information carried in the configuration message of the tracking reference signal. The UE obtains the port number of the synchronization reference signal associated with the corresponding tracking reference signal configuration by using the bit field indicating availability in the paging related message.

[0266] In some embodiments, the UE obtains the port information in the following manner:

[0267] The UE obtains information related to the energy of a certain reference signal configured by the system, such as the RSRP energy threshold, through network broadcast messages. The UE listens to the synchronization signal transmission block according to the time-frequency resource location of the synchronization signal transmission block specified by the broadcast message or protocol. When it detects that the energy consumption is higher than the RRP energy threshold, the UE obtains information about the port from the PBCH of this synchronization signal transmission block and uses this port-related information, such as the receiving port, to receive the first paging message.

[0268] In some embodiments, after the UE receives the first paging information, if it confirms that it will continue to receive the second / third paging information, it will still listen based on the information related to this port.

[0269] In some embodiments, the mapping relationship between Synchronous Transmission Block (SSB) / TRS and paging-related information depends on a certain mapping ratio and mapping order.

[0270] In some embodiments, the mapping order described above includes the ordering criteria for Synchronization Transmission Blocks (SSBs) / TRSs and paging messages, and the SSBs and paging messages are encoded according to one of the following ordering criteria:

[0271] First priority is frequency domain resources; second priority is time domain resources; third priority is code domain resources, such as SSB / TRS port resources, DMRS for paging messages, or receiver port resources.

[0272] First priority code domain resources (e.g., SSB / TRS port resources, DMRS or receive port resources for paging messages, etc.); second priority time domain resources; third priority frequency domain resources.

[0273] First priority code domain resources (e.g., SSB / TRS port resources, DMRS or receive port resources for paging messages, etc.); second priority frequency domain resources; third priority time domain resources.

[0274] In some embodiments, the mapping order described above is obtained through mathematical operations, such as multiplication and division, on the following types of information within a certain association period:

[0275] SSB / TRS port resources, time domain resources, frequency domain resources; time domain resources, frequency domain resources, code domain resources where the paging message is located, such as the synchronization sequence root sequence group number, sequence number, and DMRS port number.

[0276] In some embodiments, the synchronization resource block information configuration includes at least two sets:

[0277] The first set can use more than one port for transmission; the second set can only use one port for transmission.

[0278] In some embodiments, port information may be carried by second paging information, which can be carried either explicitly or implicitly. Explicit carrying may involve directly carrying the port number information. Implicit carrying may involve carrying the corresponding synchronization signal transmission block information, such as a synchronization signal transmission block index.

[0279] In some embodiments, the first paging information may be an ultra-low power wake-up signal, modulated using ASK / FSK / OFDM.

[0280] This disclosure proposes a paging message receiving method that is compatible with both near-field and far-field users, which can improve access efficiency and bring energy-saving effects.

[0281] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0282] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0283] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits.
