[0023] This disclosure provides a communication method, communication device, communication system, storage medium, and program product.

[0024] In a first aspect, embodiments of this disclosure provide a communication method, wherein the method is executed by a terminal, the method comprising: a first transceiver of the terminal performing a first operation, the first operation being not a data transmission related operation, and the data transmission related operation being executed by a second transceiver of the terminal; wherein the power consumption of the first transceiver is lower than the power consumption of the second transceiver.

[0025] In the above embodiments, the terminal supports using the first transceiver to perform a first operation, which is different from the operation related to data transmission. This allows the terminal to use the second transceiver only when data transmission is required, and to use the first transceiver with lower power consumption when data transmission is not required. This further reduces the power consumption of the terminal and improves the user experience.

[0026] In conjunction with some embodiments of the first aspect, in some embodiments, the first transceiver based on the terminal performs a first operation, including: measuring a first reference signal based on the first transceiver, the first reference signal being sent by a network device, the measurement power consumption corresponding to the first reference signal being less than the measurement power consumption corresponding to a second reference signal, and the second reference signal being measured by the terminal through a second transceiver.

[0027] In the above embodiments, the terminal can use a first transceiver with lower power consumption to measure the first reference signal sent by the network device. On the one hand, this allows the terminal to determine the network environment based on the measurement results so as to carry out subsequent services, and on the other hand, it can reduce the power consumption of the terminal.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the first transceiver based on the terminal performs a first operation, including at least one of the following: selecting a communication area based on the first transceiver; reselecting the communication area based on the first transceiver; wherein the communication area is the coverage area of ​​a signal of a first frequency band, the first frequency band is the operating frequency band supported by the first transceiver, and the communication area is used for the terminal to access the network.

[0029] In the above embodiments, the terminal can use a first transceiver with lower power consumption to perform the selection and / or reselection of communication areas, thereby reducing the power consumption of the terminal while enabling the terminal to reside in a communication area with higher signal quality and improving the communication quality of the terminal.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, the selection of a communication area is performed based on a first transceiver, including: measuring a first reference signal of the first communication area based on the first transceiver; and determining the first communication area as a communication area for residing if the measurement result of the first communication area is greater than or equal to a first threshold.

[0031] In the above embodiments, the terminal can measure the first reference signal of the first communication area based on the first transceiver, and determine to reside in the first communication area when the measurement result is greater than or equal to the first threshold. This not only completes the selection of the communication area, but also reduces the complexity of the process of the terminal selecting the communication area based on the first transceiver and reduces the power consumption of the terminal.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the selection of a communication area based on a first transceiver includes: searching for at least one candidate frequency band based on the first transceiver to determine at least one candidate area operating on at least one candidate frequency band; measuring a first reference signal of the at least one candidate area based on the first transceiver; and determining a communication area for camping from the at least one candidate area based on the measurement results of the at least one candidate area.

[0033] In the above embodiments, by utilizing at least one candidate frequency band, the terminal can measure only at least one candidate region obtained by searching based on at least one candidate frequency band, which can effectively improve the search efficiency of the first transceiver and reduce the power consumption of the terminal.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, performing a reselection of a communication area based on a first transceiver includes: measuring a first reference signal of at least one second communication area based on the first transceiver; the second communication area being adjacent to the first communication area where the terminal is currently camped; and determining the communication area to be reselected from the at least one second communication area based on the measurement results of the at least one second communication area.

[0035] In the above embodiments, the terminal can measure the adjacent communication area (i.e. the second communication area) based on the first transceiver, and select a reselected communication area from the adjacent communication areas based on the measurement results of the adjacent communication areas, thereby effectively reducing the complexity of the terminal's reselection of the communication area based on the first transceiver and reducing the terminal's power consumption.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, performing a reselection of a communication area based on a first transceiver includes: measuring a first reference signal of at least one third communication area based on the first transceiver, wherein the at least one third communication area is a communication area among at least one first communication area, and the third communication area is determined by the frequency band priority of at least one second communication area; and determining the reselected communication area from the at least one third communication area based on the measurement results of the at least one third communication area.

[0037] In the above embodiments, the terminal can determine at least one third communication area from at least one adjacent communication area (i.e., a second communication area) based on the frequency band priority of the communication area, and perform measurements on the at least one third communication area based on the first transceiver. Based on the measurement results of the at least one third communication area, the terminal determines the communication area to be reselected from the at least one third communication area. This allows the terminal to consider the frequency band priority of the communication area when performing communication area reselection based on the first transceiver, which is beneficial for optimizing network resource allocation.

[0038] In conjunction with some embodiments of the first aspect, in some embodiments, at least one third communication region is a communication region in at least one first communication region whose frequency band priority is higher than that of the first communication region. Determining the reselected communication region from at least one third communication region based on the measurement results of at least one third communication region includes: determining the communication region in at least one third communication region whose measurement results are greater than a second threshold as the reselected communication region.

[0039] In the above embodiments, the terminal can measure adjacent high-priority communication areas based on the first transceiver, and determine the high-priority communication areas whose measurement results are greater than the second threshold as the reselected communication areas. This can effectively reduce the complexity of the terminal's reselection of communication areas based on the first transceiver, reduce the terminal's power consumption, and optimize network resource allocation.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, the measurement result of the first communication region is less than a third threshold, and at least one third communication region is a communication region in at least one second communication region whose frequency band priority is lower than that of the first communication region. Determining the reselected communication region from at least one third communication region based on the measurement result of at least one third communication region includes: determining the communication region in at least one third communication region whose measurement result is greater than a second threshold as the reselected communication region.

[0041] In the above embodiments, if the measurement result of the first communication area where the terminal is currently stationed is less than the third threshold, the terminal can measure the adjacent low-priority communication areas based on the first transceiver, and determine the low-priority communication areas whose measurement results are greater than the second threshold as the communication areas to be reselected. This can effectively reduce the complexity of the process of the terminal reselecting the communication area based on the first transceiver, reduce the power consumption of the terminal, and improve the communication quality.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: reporting a communication area change based on a first transceiver when the terminal accesses the network through a reselected communication area.

[0043] In the above embodiments, when the communication area where the terminal resides changes, the terminal can use the first transceiver to report the change in communication area, so that the network device can be informed of the change in the terminal's communication area in a timely manner, which is beneficial to optimizing the allocation of network resources.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, a first transceiver based on a terminal performs a first operation, including: receiving first configuration information sent by a network device based on the first transceiver, the first configuration information being used for the terminal to access a communication area to be camped or to be reselected.

[0047] In the above embodiments, the first configuration information can be used by the terminal to listen to the first synchronization signal in the communication area for synchronization, or it can be used by the terminal to receive the first system information by the first transceiver, which is beneficial to ensuring the communication environment during the process of the terminal residing in the communication area, or it can be used by the terminal to perform communication area reselection by the first transceiver, which is beneficial to improving communication quality.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: receiving first system information sent by a network device based on a first transceiver, the first system information being system information supported by the first transceiver, the first system information including second configuration information, the second configuration information being used for the terminal to listen to LP-WUS.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the first system information further includes at least one of the following: first indication information for indicating the search space of paging downlink control information (DCI); and second indication information for indicating paging configuration parameters.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, a first transceiver based on the terminal performs a first operation, including: listening to LP-WUS based on the first transceiver; determining that LP-WUS has been detected, waking up a second transceiver; wherein the second transceiver is used to perform cell selection and initiate random access to the network device corresponding to the target cell, the cell selection being used to determine the target cell where the terminal is camped.

[0053] In the above embodiments, when the first system information includes the second configuration information, the terminal can use the first transceiver to listen for LP-WUS and wake up the second transceiver upon detecting LP-WUS. The woken-up second transceiver then performs data transmission-related operations such as cell selection and initiating random access, thereby reducing the terminal's power consumption.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: listening to a paging DCI based on a second transceiver, the paging DCI being used to indicate the transmission resources of a paging message; determining that a paging DCI has been detected, and listening to the paging message on the transmission resources based on the second transceiver; and, if a paging message has been detected, initiating random access to the network device corresponding to the target cell based on the second transceiver.

[0055] In the above embodiments, after the terminal wakes up the second transceiver, it can listen to the paging DCI and paging messages based on the second transceiver so as to initiate random access when the terminal is paging.

[0057] In the above embodiments, when the first system information also includes first indication information, the terminal can use the first transceiver to listen for LP-WUS, and upon listening for LP-WUS, continue to use the first transceiver to listen for paging DCI. Upon listening for paging DCI, the terminal wakes up the second transceiver. The woken-up second transceiver can directly listen for paging messages, and initiate random access upon listening for paging messages, thereby further reducing the frequency of the second transceiver being woken up and lowering the terminal's power consumption.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the first system information includes first indication information and second indication information. Determining that LP-WUS has been detected and waking up the second transceiver includes: determining that LP-WUS has been detected, listening to the paging DCI in the search space of the paging DCI based on the first transceiver; the paging DCI is used to indicate the transmission resources of the paging message; if the paging DCI has been detected, listening to the paging message in the transmission resources according to the paging configuration parameters; determining that the paging message has been detected and waking up the second transceiver.

When the terminal detects a paging message, it wakes up the second transceiver. The woken-up second transceiver can directly initiate random access, further reducing the frequency of the second transceiver being woken up and reducing the power consumption of the terminal.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, after waking up the second transceiver, the method further includes: shutting down or putting the first transceiver to sleep; and performing mobility management based on the second transceiver, the mobility management being used to determine the serving cell of the terminal.

[0108] Figure 1 is a schematic diagram of the architecture of a communication system according to an exemplary embodiment. As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102. In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0109] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home, but is not limited thereto.

[0110] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in 6G system, open RAN, cloud RAN, base station in other communication systems, and access node in Wi-Fi system.

[0111] In some embodiments, the technical solutions of this disclosure can be applied to the open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0112] 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.

[0113] In some embodiments, the CU may include a control plane (CP) and a user plane (UP).

[0114] In some embodiments, the CP (CU-CP) and UP (CU-UP) of the CU can be on different physical devices. Alternatively, the CU-CP and CU-UP can be on the same physical device.

[0115] In some embodiments, the CU may include a CU-CP and one or more CU-UPs. The CU-CP and CU-UP are connected via an E1 interface; the CU-CP and DU are connected via an F1-C interface; and the CU-UP and DU are connected via an F1-U interface.

[0116] In some embodiments, a core network device may be a single device including one or more network functions, or it may be multiple devices or a group of devices, each including all or part of one or more network functions. Network functions may be virtual or physical. The core network may include, for example, at least one of the following: evolved packet core (EPC), 5G core network (5GCN), 6G core network (6GCN), and next-generation core (NGC).

[0117] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0118] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0119] The embodiments disclosed herein 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), 5G, 5G New Radio (NR), 6G, 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), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth, and public terrestrial mobile communication networks. Land Mobile Networks (PLMNs), 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. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0120] In some embodiments, the LP-WUR can include two types. The first type of LP-WUR only supports envelope detection of on-off keying (OOK) symbols of the LP-WUS; this type of LP-WUR can be called an OOK LR, and its link performance is relatively poor. The second type of LP-WUR supports detection of orthogonal frequency division multiplexing (OFDM) time-domain or frequency-domain sequences carried by the OOK symbols of the LP-WUS, thereby improving link performance; this type of LP-WUR can be called an OFDM LR. In one embodiment, the OFDM LR can also detect the primary synchronization signal (PSS) or secondary synchronization signal (SSS); however, if the PSS or SSS is not within the frequency band supported by the OFDM LR, the OFDM LR cannot receive it.

[0121] In some embodiments, for proper LP-WUS detection, the terminal needs to obtain the time and frequency location of the LP-WUS transmission from the access network device. In one embodiment, the terminal can obtain and maintain time and frequency synchronization by detecting synchronization signals. In one example, when the terminal activates the main radio (MR), it can obtain synchronization by detecting the synchronization signal block (SSB). When the MR is off and the LR is on, the terminal can maintain synchronization using low-power synchronization signals (LP-SS) dedicated to LP-WUS. In one embodiment, for OFDM LR, OFDM LR can also maintain synchronization by detecting the SSB. In one embodiment, in addition to being used for synchronization, LP-SS can also serve as a reference signal for RRM measurement.

[0122] In some embodiments, the access network device can broadcast the frequency domain locations of the cell's LP-WUS and LP-SS to the terminal via system information. Terminals in Radio Resource Control (RRC) idle state can obtain the configuration information (e.g., frequency domain location, time domain location, function information, etc.) of the cell's LP-WUS or LP-SS by listening to system messages. Thus, when the terminal determines to enter MR sleep state, it can use LR to listen for LP-SS or LP-WUS at the configured frequency or time domain locations.

[0123] In some embodiments, during terminal movement, the LR (Lower Receptor) cannot be used directly for cell reselection; instead, the MR (Middle Receptor) must be used to perform neighbor cell measurements for cell reselection. In some embodiments, the reception of paging messages and system messages, as well as the transmission and reception of uplink and downlink data, are also performed by the MR. That is, even if a lower-power LR is introduced into the terminal, the energy-saving effect is limited.

[0124] Therefore, this disclosure proposes a communication method, communication device, communication system, storage medium, and program product. By implementing some functions of the MR by the LR, the terminal resides through the LR and only wakes up the MR when data transmission is required, thus further saving power for the terminal.

[0125] Figure 2A is an interactive schematic diagram of a communication method according to an exemplary embodiment. As shown in Figure 2A, this disclosure relates to a communication method for a communication system 100. The method includes steps S2101 to S2106.

[0126] In step S2101, the terminal performs a first operation based on the first transceiver.

[0127] In some embodiments, the terminal may include a first transceiver and a second transceiver.

[0128] In some embodiments, the power consumption of the first transceiver in its operational state is less than that of the second transceiver in its operational state. In some embodiments, the capability of the first transceiver is weaker than that of the second transceiver. In one embodiment, the first transceiver may be an LP-WUR transceiver, and the second transceiver may be an MR transceiver.

[0129] In some embodiments, the first operation is not a data transmission related operation. In some embodiments, the first operation can be an operation other than a data transmission related operation.

[0130] In some embodiments, data transmission-related operations may be performed by a second transceiver of the terminal. In some embodiments, operations other than data transmission-related operations may be performed by a first transceiver of the terminal. In one embodiment, the first transceiver may perform all operations except data transmission, while the second transceiver performs only data transmission-related operations. This allows the terminal to wake up the second transceiver only when data transmission is required, further reducing the terminal's power consumption.

[0131] In some embodiments, the terminal performing a first operation based on the first transceiver may include: the terminal measuring a first reference signal based on the first transceiver.

[0132] In some embodiments, the first reference signal is a reference signal associated with the first transceiver.

[0144] In some embodiments, the communication area may be a communication area that the terminal's first transceiver supports access to. In some embodiments, the first configuration information may be used to indicate at least one of the following: frequency band priority of multiple communication areas supported by the first transceiver, measurement parameters for communication area reselection, and a first condition.

[0145] In some embodiments, the measurement parameters for communication area reselection may be parameters related to signal quality. In one embodiment, the measurement parameters for communication area reselection include, but are not limited to: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR).

[0146] In some embodiments, the first condition may be used by the terminal to perform communication area reselection based on the first transceiver. In some embodiments, the first condition may include at least one of the following: a second condition, a third condition, and a fourth condition.

[0147] In some embodiments, the second condition may be used by the terminal to determine the target communication area for reselection from at least one adjacent communication area based on the first transceiver.

In one embodiment, the second condition may be that the signal quality of the adjacent communication area is better than the signal quality of the communication area where the terminal is currently camped.

[0148] In some embodiments, the third condition can be used by the terminal to determine the target communication area for reselection from at least one adjacent communication area with higher frequency band priority based on the first transceiver.

In one embodiment, the third condition can be that the signal quality of an adjacent high-priority communication area is higher than a second threshold.

In one embodiment, the fourth condition can be that the signal quality of an adjacent low-priority communication area is higher than a second threshold, and the signal quality of the communication area where the terminal is currently camped is lower than a third threshold.

[0150] In some embodiments, the terminal performing the first operation based on the first transceiver may further include: the terminal performing the selection of a communication area based on the first transceiver.

[0151] In some embodiments, the terminal may measure a first reference signal of a first communication area based on a first transceiver. If the measurement result of the first communication area is greater than or equal to a first threshold, the terminal may determine the first communication area as a communication area for camping. In one embodiment, the terminal may perform a full-band search based on the first transceiver to determine at least one first communication area supported by the first transceiver, and measure the first reference signal of the at least one first communication area based on the first transceiver. Based on the measurement results of the at least one first communication area, the terminal may determine the first communication area whose measurement result is greater than or equal to the first threshold as a communication area for camping.

In some embodiments, the measurement results of the communication region for camping are superior to the measurement results of other communication regions besides the communication region in the at least one candidate region. In one embodiment, the terminal may not perform a full-band search, but instead search for at least one candidate frequency band based on the first transceiver to obtain at least one candidate region. The terminal may measure the first reference signal of the at least one candidate region based on the first transceiver and select the candidate region with the best signal quality from the at least one candidate region as the communication region for camping.

[0153] In some embodiments, the terminal may independently determine at least one candidate frequency band for selecting a communication area. In one embodiment, this is provided by the terminal's non-access stratum (NAS). In another embodiment, the at least one candidate frequency band may be determined by the terminal based on pre-stored historical information.

[0154] In some embodiments, the terminal may determine at least one candidate frequency band for selecting a communication area based on instructions from the network device. In one embodiment, the terminal may receive first information sent by the network device, which may be used to indicate at least one candidate frequency band.

[0166] In some embodiments, when a terminal accesses the network through a reselected communication area, the terminal can report the communication area change based on a first transceiver. In one embodiment, after the terminal completes the reselection of the communication area, the terminal can notify the network device of the change in its residing communication area.

[0167] In some embodiments, the terminal's reporting of a communication area change based on the first transceiver can be achieved by the terminal sending a first signal to the network device based on the first transceiver. This first signal indicates a change in the communication area. In some embodiments, unlike the signals used for data transmission between the terminal and the network device, the first signal sent by the terminal based on the first transceiver can be a simple physical layer signal. In one embodiment, the first signal can be a physical layer signal sent according to a preset sequence, and this physical layer signal may not carry any information content.

[0168] In some embodiments, the terminal can receive first system information sent by the network device based on the first transceiver.

[0176] In some embodiments, the terminal can listen to LP-WUS based on the second configuration information.

[0177] In step S2102, if the terminal detects LP-WUS, the terminal wakes up the second transceiver.

[0178] In some embodiments, LP-WUS can be used to wake up a second transceiver.

[0179] In some embodiments, if the terminal detects LP-WUS targeting itself based on the first transceiver, the terminal wakes up the second transceiver.

[0180] In one embodiment, when the terminal detects an LP-WUS, it can decode the detected LP-WUS to obtain the identification information carried within the LP-WUS. The terminal can then match the decoded identification information with its own identification information to determine whether the LP-WUS is specific to itself. In one embodiment, if the decoded identification information matches its own identification information, the terminal can determine that the LP-WUS is specific to itself, and in this case, the terminal can wake up the second transceiver. In another embodiment, if the decoded identification information does not match its own identification information, the terminal can determine that the LP-WUS is not specific to itself, and in this case, the terminal can determine that it has not detected an LP-WUS and does not need to wake up the second transceiver. In this case, steps S2102 to S2106 can be omitted.

[0181] In one embodiment, when a terminal detects a first type of LP-WUS, the terminal can match the terminal identifier carried in the first type of LP-WUS with its own terminal identifier to determine whether the first type of LP-WUS is an LP-WUS specific to itself.

[0182] In one embodiment, when a terminal detects a second type of LP-WUS, the terminal can match the terminal group identifier carried in the second type of LP-WUS with the group identifier to which it belongs to, in order to determine whether the second type of LP-WUS is an LP-WUS for itself.

[0183] In some embodiments, after the terminal wakes up the second transceiver, the terminal may shut down the first transceiver.

[0184] In step S2103, the terminal performs a second operation based on the second transceiver.

In one embodiment, after the terminal wakes up the second transceiver, it may use the second transceiver to perform cell selection to choose a suitable cell to camp on. In one embodiment, the terminal may access the network by accessing the target cell, so that the terminal may subsequently perform paging DCI and / or paging message listening based on the second transceiver.

[0188] In some embodiments, the terminal may measure the second reference signal of at least one cell based on the second transceiver, and the terminal may determine the target cell from the at least one cell based on the measurement results of the at least one cell. In one embodiment, the terminal may select the cell with the best measurement result from the at least one cell, determine the cell with the best measurement result as the target cell, and camp on the target cell.

[0189] In some embodiments, after the terminal selects a target cell to camp on, the terminal can listen to the paging DCI using a second transceiver. In some embodiments, the terminal can use the second transceiver to listen to the paging DCI in the search space of the paging DCI in order to determine the transmission resources of the paging message based on the paging DCI.

[0190] In some embodiments, the terminal can determine the search space for paging DCI based on second system information sent by the network device corresponding to the target cell. In one embodiment, after the terminal camps on the target cell, it can receive the second system information sent by the network device corresponding to the target cell.

[0191] In some embodiments, the second system information is system information supported by the second transceiver. In some embodiments, the second system information differs from the first system information. In some embodiments, the second system information may include, but is not limited to: common configuration information of the physical downlink control channel (PDCCH) and random access parameters of the target cell.

[0192] In some embodiments, the common configuration information of the PDCCH can be used by the terminal to determine the search space of the paging DCI. In some embodiments, the paging DCI can be used to indicate the transmission resources for paging messages.

[0193] In some embodiments, the random access parameters of the target cell can be used by the terminal to initiate random access to the network device of the target cell.

[0194] In some embodiments, when a terminal detects a paging DCI, the terminal can listen for paging messages on the transmission resources indicated by the paging DCI using a second transceiver.

[0195] In some embodiments, a paging message may include a paging identifier, which indicates the terminal being paged. In one embodiment, when a terminal detects a paging message, it can decode the detected paging message to obtain the paging identifier carried within the paging message. The terminal can then match the decoded paging identifier with its own identifier information to determine whether the paging message is addressed to it. In one embodiment, if the decoded paging identifier matches its own identifier information, the terminal can determine that the paging message is addressed to it, and in this case, the terminal determines that it has received the paging message. In one embodiment, if the decoded paging identifier does not match its own identifier information, the terminal can determine that the paging message is not addressed to it, and in this case, the terminal has not received the paging message.

[0196] In some embodiments, if the terminal does not listen to the paging DCI, the terminal may not listen to the paging message.

[0197] In some embodiments, when a terminal detects a paging message, the terminal can initiate random access to the network device corresponding to the target cell based on a second transceiver. In one embodiment, the terminal can initiate random access using a second transceiver according to the random access parameters of the target cell, so as to perform data transmission after the terminal establishes an RRC connection with the network device.

[0198] In some embodiments, the terminal may determine the random access parameters of the target cell based on the second system information.

[0199] In some embodiments, the terminal may determine the random access parameters of the target cell based on first system information. In some embodiments, the first system information may include the random access parameters of at least one candidate cell. If the target cell is included in the at least one candidate cell, the terminal may determine the random access parameters of the target cell based on the first system information.

[0200] In some embodiments, if the terminal does not receive a paging message, the terminal may not initiate random access.

[0201] In step S2104, the terminal performs mobility management based on the second transceiver.

[0202] In some embodiments, mobility management can be used to determine the serving cell of a terminal.

[0203] In some embodiments, the terminal performing mobility management based on the second transceiver may include: the terminal performing cell reselection or cell handover based on the second transceiver. In one embodiment, the terminal may measure a second reference signal of at least one neighboring cell based on the second transceiver, and determine the target cell for cell reselection or cell handover based on the measurement results of at least one neighboring cell.

[0204] In some embodiments, if the signal strength of the cell where the terminal is currently camped is good, the terminal may not need to perform mobility management. In this case, step S2104 can be omitted.

[0205] In some embodiments, after the terminal performs mobility management based on the second transceiver, the terminal can determine whether the communication area to which the serving cell belongs has changed. If the communication area to which the terminal's serving cell belongs has changed, the terminal can send first information to the network device based on the second transceiver. In some embodiments, the first information can be used to indicate that the communication area where the terminal is located has changed.

[0206] In some embodiments, before the terminal determines whether the communication area to which the serving cell belongs has changed, the terminal may determine the association between the communication area and the cell according to the protocol. In some embodiments, the terminal may determine whether the communication area to which the serving cell belongs has changed based on the association between the communication area and the cell as agreed in the protocol.

[0207] In some embodiments, before the terminal determines whether the communication area to which the serving cell belongs has changed, the terminal may receive second information sent by the network device. This second information may be used to indicate the association between the communication area and the cell. In some embodiments, the second information may be used by the terminal to determine whether the communication area to which the serving cell belongs has changed.

[0208] In step S2105, if the occurrence of the first event is determined, the terminal shuts down the second transceiver.

[0209] In some embodiments, upon determining that a first event has occurred, the terminal may shut down the second transceiver and wake up the first transceiver. In some embodiments, the first event may be used to trigger the terminal to switch to using the first transceiver.

[0210] In some embodiments, the first event may include: the terminal stops data transmission for a predetermined duration. In some embodiments, after the terminal determines that the data transmission stoppage time exceeds the predetermined duration, the terminal may shut down the second transceiver and wake up the first transceiver. In one embodiment, when the terminal has data transmission needs, the terminal wakes up the second transceiver and uses the second transceiver to perform data transmission. When the terminal has not performed data transmission for a long time, in order to reduce the terminal's power consumption, the terminal may shut down the second transceiver and wake up the first transceiver.

[0211] In some embodiments, the first event may include the network device sending an instruction message to the terminal instructing the terminal to shut down the second transceiver. In some embodiments, the instruction message instructing the terminal to shut down the second transceiver may be a third instruction message. In some embodiments, upon receiving the third instruction message sent by the network device, the terminal may shut down the second transceiver and wake up the first transceiver based on the third instruction message.

[0212] In some embodiments, the first event may include the network device sending indication information to the terminal to indicate that the terminal has transitioned from an RRC connected state to an RRC disconnected state. In some embodiments, the indication information to indicate that the terminal has transitioned from an RRC connected state to an RRC disconnected state may be fourth indication information. In some embodiments, when the terminal receives the fourth indication information sent by the network device, based on the fourth indication information, the terminal may shut down the second transceiver and wake up the first transceiver.

[0213] In some embodiments, if the terminal does not detect the first event, the terminal continues to perform the second operation based on the second transceiver without needing to shut down the second transceiver. In this case, steps S2105 and S2106 can be omitted.

[0214] In step S2106, the terminal performs a first operation based on the first transceiver.

[0427] To better understand the embodiments of this disclosure, the following exemplary embodiments will be used to further illustrate this disclosure.

[0428] Example 1: A specific type of terminal uses a first transceiver to perform a first action.

[0429] The first transceiver in this article includes a receiver with receiving function, or a transmitter with transmitting function, or a receiver with both receiving and transmitting functions.

[0430] In some embodiments, a particular type of terminal has a first transceiver and a second transceiver. In one embodiment, the first transceiver may be a low-power transceiver (LP-WUR).

[0431] In some embodiments, the first action includes measuring a low-power signal.

[0432] In some embodiments, the first action includes residing in a communication area, such as for a low-power communication area (LR-Area).

[0433] In some embodiments, the first action includes selecting and / or reselecting a communication area, such as selecting and / or reselecting a low-power communication area (LR-Area). The LR-Area is used as an example below.

[0434] In one embodiment, the communication region, such as a low-power communication region, is an area that can be covered by at least one low-power frequency band (LR band). In one embodiment, the LR band may be the operating frequency band of a first transceiver.

[0435] In one embodiment, the selection of the communication area, such as the selection of the LR-Area, is to select the LR-Area where the terminal resides and perform the first action in that LR-Area.

[0436] In one embodiment, the reselection of the communication area, such as the reselection of the LR-Area, is to change the LR-Area where the terminal resides.

[0437] In some embodiments, the first line includes receiving configuration information for the communication area, such as configuration information for the LR-Area. In one embodiment, the configuration information for the LR-Area includes: LP-SS transmission configuration, system message transmission configuration, such as LP-SI (Low Power System Message) transmission configuration, and configuration information for LR-Area reselection.

[0438] In one embodiment, the transmission configuration of LP-SI may include the transmission configuration of LP-WUS.

[0439] In some embodiments, the first action includes receiving a paging message.

[0440] In one embodiment, the paging message includes at least one of the following: a low-power wake-up signal LP-WUS, a paging DCI, or a paging message.

[0441] In Example 2, the terminal can first select the communication area based on the first transceiver, such as the LR-Area.

[0442] In one embodiment, the terminal can use a first transceiver to detect the signal quality of the LP-SS in the first LR-Area. If the signal quality of the LP-SS in the first LR-Area exceeds a first threshold, the terminal can choose to perform a first action in the first LR-Area.

[0443] In one embodiment, an LR-Area is a communication area deployed on an LR band. One or more LR-Areas may be deployed on an LR band. In one embodiment, a terminal can use a first transceiver to detect the signal quality of the LP-SS of at least one candidate LR band's corresponding LR-Area, select the LR-Area with the strongest signal quality as the target LR-Area, and perform the first action in the target LR-Area.

[0444] In one embodiment, the terminal does not distinguish the priority of LR bands when selecting LR-Area.

[0445] In one embodiment, the candidate LR band when the terminal selects an LR-Area can be provided by the NAS. In another embodiment, the candidate LR band when the terminal selects an LR-Area can be determined based on historical information stored in the terminal.

[0446] In one embodiment, the candidate LR band when the terminal selects an LR-Area can be explicitly indicated by the network, for example, when the terminal transitions from a connected state to a disconnected state, as indicated by the network.

[0447] In Example 3, the terminal can perform communication area reselection based on the first transceiver, such as LR-Area reselection.

[0448] In one embodiment, the terminal can obtain the priority level of the LR band of the network broadcast.

[0449] In one embodiment, when certain conditions are met, the terminal performs measurements on the neighboring LR band or neighboring LR-Area based on the first transceiver.

[0450] In one example, if the neighboring LR band has a higher priority, the terminal can measure the neighboring LR band based on the first transceiver.

[0451] In one example, if the neighboring LR band has a lower priority and the signal quality of the LP-SS in this LR-Area is lower than a first threshold, the terminal can measure the neighboring LR band based on the first transceiver.

[0452] In one embodiment, the terminal can detect the signal quality of the LP-SS in a neighboring LR-Area. If the signal quality of the LP-SS in a neighboring LR-Area exceeds that of the LP-SS in the current LR-Area, then that neighboring LR-Area is identified as the target LR-Area for reselection, and the first action is performed in that target LR-Area. In this case, the terminal does not distinguish the priority of the LR band when reselecting the LR-Area.

[0453] In one embodiment, the terminal can sort neighboring LR bands according to their priority level and measure the neighboring LR bands based on the priority level.

[0454] In one embodiment, if the neighboring LR band has a higher priority, the terminal detects the signal quality of the LP-SS of the neighboring LR-Area based on the first transceiver. If the signal quality of a neighboring LR-Area exceeds a second threshold, that neighboring LR-Area is identified as the target LR-Area for reselection, and the first action is performed in that target LR-Area. In this case, the terminal distinguishes the priority of the LR band when reselecting the LR-Area.

[0455] In one embodiment, if the priority of a neighboring LR band is lower, the terminal detects the signal quality of the LP-SS of the neighboring LR-Area based on the first transceiver. If the signal quality of a neighboring LR-Area exceeds a second threshold, and the signal quality of the LP-SS of the current LR-Area is lower than a first threshold, then the neighboring LR-Area is identified as the target LR-Area for reselection, and the first action is performed in the target LR-Area. In this case, the terminal distinguishes the priority of LR bands when performing LR-Area reselection.

[0456] In some embodiments, if a terminal leaves one LR-Area and enters another LR-Area, the terminal can notify the network. In one embodiment, the terminal can notify the network by sending a notification message via a first transceiver, which can indicate an update of the LR-Area.

[0457] In some embodiments, the terminal may periodically notify the network whether to update the LR-Area.

[0458] Example 4: The terminal can listen to system messages, such as low-power system messages, LR-SI, and obtain LP-WUS configuration information based on LR-SI.

[0459] In some embodiments, in order to enable the rapid initiation of services by the second transceiver, some information from the system messages that need to be listened to by the second transceiver can be carried and sent in the configuration information of the LR-Area.

[0460] In one embodiment, LR-SI may include only the configuration information of LP-WUS.

[0461] In one embodiment, LR-SI may include LP-WUS configuration information and paging DCI search space information.

[0462] In one embodiment, the LR-SI may include LP-WUS configuration information, paging DCI search space information, and paging configuration parameters. In one embodiment, the LR-SI may include RACH parameters. In another embodiment, the LR-SI may include RACH parameters for multiple candidate cells. Thus, after being woken up, the terminal activates its second transceiver and can utilize the RACH parameters to quickly establish access.

[0463] Example 5: The terminal listens to LP-WUS through the first transceiver.

[0464] In one embodiment, the wake-up granularity of LP-WUS can be per UE or per UE group.

[0465] In one embodiment, if the wake-up granularity of LP-WUS is terminal granularity (per UE), then LP-WUS may include a terminal identifier.

[0466] In Example 6, after the terminal detects that LP-WUS has been woken up based on the first transceiver, it will perform the second action.

[0467] In one embodiment, if the first transceiver only supports listening to LP-WUS, the terminal will perform a second action after listening to LP-WUS. In this case, the second action includes turning on the second transceiver, performing cell selection based on the second transceiver, and listening to paging DCI and paging messages in the selected cell.

[0468] In one embodiment, assuming the first transceiver supports monitoring LP-WUS and paging DCI, after the terminal detects LP-WUS, it monitors the PDCCH. If, after decoding the PDCCH, it is determined that the terminal is a woken-up user, the terminal performs a second action. In this case, the second action includes activating the second transceiver, performing cell selection based on the second transceiver, and monitoring paging messages in the selected cell. It should be noted that this scenario requires the first transceiver to support the paging search space for paging DCI.

[0469] In one embodiment, assuming the first transceiver supports monitoring LP-WUS, paging DCI, and paging messages, after the terminal detects LP-WUS, it monitors the PDCCH and performs PDCCH and PDSCH decoding. If the PDCCH and PDSCH decoding determines that the terminal is a woken-up user, the terminal performs a second action. In this case, the second action includes activating the second transceiver, performing cell selection based on the second transceiver, and directly initiating a RACH request in the selected cell. It should be noted that this scenario requires the first transceiver to support the paging search space of paging DCI.

[0470] In Example 7, after the second transceiver is woken up, it will perform cell measurement to select a cell to camp on, and then perform subsequent services after camping, such as initiating a RACH request.

[0471] In Example 8, after the second transceiver is woken up, it will perform cell measurement to select a cell to camp on, and then perform mobility management after camping.

[0472] In one embodiment, the terminal may shut down the first transceiver.

[0473] In one embodiment, if the first transceiver is turned off, the terminal will use the second transceiver for mobility management, such as measuring neighboring cells for cell handover. If the terminal discovers a change in the LR-Area location after a cell handover, it will notify the network to update the LR-Area via the second transceiver.

[0474] In one embodiment, the network can inform the terminal in advance of the association between the cell and the LR-Area. For example, the association between the cell and the LR-Area can indicate which LR-Area the cell belongs to. In this way, the terminal can determine whether an LR-Area change has been made.

[0475] Example 9: After the terminal performs the second action using the second transceiver, it will continue to fall back to the first action when certain conditions are met.

[0476] In one embodiment, if there is no uplink or downlink transmission within a first time T after data transmission stops, the terminal shuts down the second transceiver and uses the first transceiver to perform the first action.

[0477] In one embodiment, if the network instructs the terminal to shut down the second transceiver, the terminal shuts down the second transceiver according to the network instruction and performs the first action using the first transceiver.

[0478] In one embodiment, if the network sends an instruction to the terminal to instruct the terminal to enter the RRC disconnected state from the RRC connected state, the terminal may shut down the second transceiver and use the first transceiver to perform the first action.

[0479] In one embodiment, the terminal falls back to the first action, i.e., the terminal performs the action of selecting LR-Area in Embodiment 2.
