Description

Communication method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method and device.

Background

When the network device needs to send downlink data to the terminal device in the idle state or the inactive state, the network device sends a paging (paging) message to the terminal device to page the terminal device. After receiving the Paging message, the terminal device in the idle state or the inactive state may initiate a Radio Resource Control (RRC) connection establishment procedure to receive a call.

In the New Radio (NR) technique, a paging message is carried on an initial downlink bandwidth part (initial downlink BWP) corresponding resource.

At present, besides some first terminal devices with normal functions, some terminal devices with limited capabilities exist, such as NR lightweight (light) terminal devices or reduced capability (redcapability) terminal devices. For NR light end devices, the bandwidth may be limited and the operating bandwidth of the end device may be smaller than the initial downlink BWP. Therefore, the network device sends the paging message on the resource of the initial downlink BWP, and some NR light terminal devices may not be able to monitor the paging message, thereby affecting the subsequent downlink data transmission.

Disclosure of Invention

The embodiment of the application provides a communication method and a communication device, which can effectively avoid the problem that downlink data transmission is influenced by the fact that a terminal device with limited capability cannot monitor a paging message.

In a first aspect, embodiments of the present application provide a communication method, which may be performed by a first communication apparatus, where the first communication apparatus may be a communication device or a communication apparatus capable of supporting the communication device to implement functions required by the method, such as a circuit or an electronic apparatus. Illustratively, the first communication device is a terminal device, or a circuit or an electronic device provided in the terminal device for implementing the function of the terminal device, or other components for implementing the function of the terminal device. In the following description, the first communication apparatus is taken as an example of the first terminal device. The communication method comprises the following steps: the method comprises the steps that first terminal equipment receives first configuration information, wherein the first configuration information comprises first information, the first information is used for configuring a transmission mode of a paging message (or a system message), and the transmission mode of the paging message (or the system message) is a frequency hopping mode or a non-frequency hopping mode; the first terminal device receives the paging message (or the system message) according to the transmission mode of the paging message (or the system message) configured by the first configuration information.

In the embodiment of the application, before receiving the paging message, the first terminal device can determine to receive the paging message in a frequency hopping mode or a non-frequency hopping mode. There may be a gain of, for example, 2-3dB due to frequency hopping. If for a terminal device with limited capability, such as an NR light terminal device, the network device may transmit the paging message (or the system message) in a frequency hopping manner, so that the terminal device receives the paging message (or the system message) in a frequency hopping manner, and a gain of the frequency hopping may meet a requirement of coverage recovery of the terminal device with limited bandwidth. For normal terminal equipment, the terminal equipment determines that the paging message can be received in a non-frequency hopping mode according to the first configuration information.

In a possible design, the first information is an indication bit, and when the indication bit is a first value, the first information indicates that the transmission mode of the paging message is a frequency hopping mode, or when the indication bit is a second value, the first information indicates that the transmission mode of the paging message is a non-frequency hopping mode. For example, when the indicator bit is 1, the transmission mode of the paging message is indicated as a frequency hopping mode, so that the first terminal device receives the paging message in the frequency hopping mode, and when the indicator bit is 0, the transmission method of the paging message is indicated as a non-frequency hopping mode, so that the first terminal device receives the paging message in the non-frequency hopping mode. For another example, when the indicator bit is 0, the transmission mode of the paging message is indicated as a frequency hopping mode, so that the first terminal device receives the paging message in the frequency hopping mode, and when the indicator bit is 1, the transmission mode of the paging message is indicated as a non-frequency hopping mode, so that the first terminal device receives the paging message in the non-frequency hopping mode. The occupation of transmission resources can be reduced because the resource occupied by the indicating bit is less.

In a possible design, the transmission mode of the paging message is a frequency hopping mode, and the first configuration information further includes location information of at least two frequency domain resources used for transmitting the paging message, in case that the first information is an indicator bit; when the first terminal device receives the paging message according to the transmission mode of the paging message configured by the first configuration information, the following mode can be implemented: and the first terminal equipment monitors the paging message on at least two frequency domain resources in a frequency hopping mode according to the first configuration information.

If the first terminal equipment is the terminal equipment with normal functions, the paging message is monitored in at least two frequency domain resources, and the coverage rate of monitoring the paging message can be improved.

For example, the first information includes information of at least two frequency domain resources used for transmitting the paging message, and the first terminal device monitors the paging message on the at least two frequency domain resources in a frequency hopping manner according to the first configuration information. For another example, the first information includes information of a frequency domain resource used for transmitting the paging message, and the first terminal device monitors the paging message in the frequency domain resource in a non-frequency hopping manner according to the first configuration information. The information of the frequency domain resources includes at least location information of the frequency domain resources. The location information of the frequency domain resources may include one or more of frequency points, carriers, frequency bands, or bandwidths of the frequency domain resources. The frequency domain resources may be BWP, or narrowband. For example, the frequency domain resource is BWP, and the information of the BWP may further include one or more of a subcarrier spacing (SCS) identifier, a control resource set (coreset) identifier, or a search space (searchspace) identifier in addition to the position information of the BWP.

For example, the frequency domain resource is BWP, and the at least two BWPs may include an initial downlink BWP or a BWP where another cell-defined synchronization signal block different from the frequency domain position of the cell-defined synchronization signal block used by the first terminal device is located.

With the above design, the first information includes location information of at least two frequency domain resources used for transmitting the paging message, and the first terminal device can determine to receive the paging message in a frequency hopping manner.

For example, the terminal device of type 1 supports a maximum bandwidth of 10MHz, and the terminal device of type2 supports a maximum bandwidth of 20 MHz. The service types supported by the terminal device include, for example, an Industrial Wireless Sensor Network (IWSN) service type, a wearable type, a monitoring service type, and the like.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

2) A network device, which may also be referred to as AN Access Network (AN) device, such as a base station (e.g., AN access point), may refer to a device in AN access network that communicates with a wireless terminal device over one or more cells over AN air interface, or, for example, a network device in vehicle-to-all (V2X) technology is a Road Side Unit (RSU). The base station may be configured to interconvert received air frames and IP packets as a router between the terminal device and the rest of the access network, which may include an IP network. The RSU may be a fixed infrastructure entity supporting the V2X application and may exchange messages with other entities supporting the V2X application. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB) or eNB or e-NodeB in an LTE system or an LTE-a (long term evolution-advanced), or may also include a next generation Node B (gNB) in a 5th generation (5G) NR system (also referred to as an NR system) or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud access network (Cloud RAN) system, which is not limited in the embodiments.

For example, may include a handheld device having wireless connection capability, or a processing device connected to a wireless modem. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchange voice or data with the RAN, or interact with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a vehicle-to-all (V2X) terminal device, a machine-to-machine/machine-type communication (M2M/MTC) terminal device, an internet of things (IoT) terminal device, a subscription unit (subscriber unit), a subscription station (IoT), a mobile station (mobile station), a remote station (remote station), an access point (access point, AP), a remote terminal (remote), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), or user equipment (user), etc. For example, mobile telephones (or so-called "cellular" telephones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-included mobile devices, and the like may be included. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable smart device or intelligent wearable equipment etc. is the general term of using wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

The various terminal devices described above, if located on a vehicle (e.g., placed in or installed in the vehicle), may be considered to be vehicle-mounted terminal devices, which are also referred to as on-board units (OBUs), for example.

In this embodiment, the terminal device may further include a relay (relay). Or, it is understood that any device capable of data communication with a base station may be considered a terminal device.

In the embodiment of the present application, the apparatus for implementing the function of the terminal device may be the terminal device, or may be an apparatus capable of supporting the terminal device to implement the function, such as a chip or a chip system, and the apparatus may be installed in the terminal device. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, a device for implementing a function of a terminal is taken as an example of a terminal device, and the technical solution provided in the embodiment of the present application is described.

4) The embodiment of the invention also relates to Core Network (CN) equipment. CN devices correspond to different devices in different communication systems, for example, a Serving GPRS Support Node (SGSN) or a Gateway GPRS Support Node (GGSN) in a 3G system, a Mobility Management Entity (MME) or a serving gateway (S-GW) in a 4G system, and a Core network related device (for example, NG-Core, AMF (Access and Mobility Management Function, Access Mobility Management entity), UPF (User Plane Function entity)) in a 5G system.

5) Bandwidth part (BWP).

In NR systems, the terminal device may only be able to operate at a relatively small operating bandwidth (e.g. 5MHz), while a cell of the network device may support a relatively large bandwidth (e.g. 100MHz), and the small bandwidth portion of the large bandwidth may be considered as BWP. The network device configures one or more BWPs to the terminal device. And updates the BWP that the terminal device can operate by activating or deactivating the BWP.

6) Synchronization Signal Block (SSB).

The SSB includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). The terminal device selects a specific SSB, called cell-defining SSB, which a cell needs to read to.

7) Frequency hopping (frequency hopping).

The frequency hopping refers to a communication mode in which both the receiving end and the transmitting end change frequency domain resources used in the information transmission process according to a predetermined rule, and can obtain a frequency diversity gain. In frequency hopping communication, a frequency point used for each carrier hops among a set of frequency points set in advance according to a certain frequency hopping sequence as a frame changes. Frequency hopping communication has good anti-jamming capability, and even if some frequency points are interfered, normal communication can still be carried out on other frequency points which are not interfered, so that certain coverage enhancement gain can be obtained by frequency hopping.

8) Paging messages.

The content of the paging message is mainly used for: indicating updates to system messages, public warning, and/or traffic arrival at the terminal device. The terminal device receives a paging message in a Discontinuous Reception (DRX) mode in an IDLE (IDLE) or INACTIVE (INACTIVE) state. The network device may use different time domain resources for sending paging messages to different terminal devices. So that different terminal devices can listen to the paging message on different time domain resources. The time domain resource includes a Paging Frame (PF) or a Paging Occasion (PO).

In the NR communication system, since the concept of beam (beam) is introduced, a PO may include multiple Physical Downlink Control Channel (PDCCH) monitoring occasions (monitoring allocations), where different PDCCH monitoring occasions correspond to different beams, that is, a PDCCH monitoring occasion carrying a paging message is transmitted on one beam. The terminal device may receive the paging message only on the PDCCH monitoring occasion corresponding to the beam where the terminal device is located. In addition, the time unit mentioned in the embodiment of the present application may be PF, PO, or PDCCH monitoring scheduling.

The position information of the PF and the PO may be calculated by the terminal device according to the user identifier of the terminal device. In this embodiment of the present application, the user Identifier of the terminal device may be one or more of an International Mobile Subscriber Identifier (IMSI)), a system architecture evolution Temporary Mobile Station Identifier (SAE Temporary Mobile Station Identifier, S-TMSI), a cell radio network Temporary Identifier (C-RNTI), and the like. In the NR system, besides calculating PF and PO, a PDCCH monitoring event corresponding to a specific beam needs to be determined.

The network device may also use different frequency domain resources for different terminal devices, in addition to dispersing the paging messages of different terminal devices to different time domain resources.

In one example, paging messages for different terminal devices are spread across different narrow bands. Such as shown in equation (1).

PNB ═ floor (UE _ ID/(Ns)) mod Nn equation (1)

Wherein, in formula (1), PNB represents a narrowband number; nn represents the number of narrow bands available on the cell for transmitting paging messages; UE _ ID represents the user identification of the terminal equipment; n represents min (T, nB); ns denotes max (1, nB/T); t represents the paging cycle of the terminal equipment; nB may be: 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, T/64, T/128, etc., nB may be configured by the network side or agreed upon by the protocol.

In another example, paging messages for different terminal devices may be spread across different carriers. Such as shown in equation (2).

floor (UE _ ID/(N × Ns)) mod W < W (0) + W (1) + … + W (N) formula (2)

In the formula (2), n represents the minimum carrier number satisfying the formula (2), n is greater than or equal to 0 and less than or equal to Nn-1, and W (i) is the distribution weight on the carrier i. Nn represents the number of carriers available on the cell to send paging messages; UE _ ID represents the user identification of the terminal equipment; n represents min (T, nB); ns denotes max (1, nB/T); t represents the paging cycle of the terminal equipment; nB may be: 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, T/64, T/128, etc., nB may be configured by the network side or agreed upon by the protocol.

In the NR system, a terminal device in an IDLE (IDLE) state or an INACTIVE (INACTIVE) state listens for a paging message only on an initial downlink bandwidth part (initial downlink BWP). That is, the network device sends the paging message to the terminal device in IDLE state or INACTIVE state on the initial downlink BWP. Different CD-SSDs belong to different frequency domain resources. The terminal device may select to camp on the cell corresponding to the CD-SSB and listen to the paging message of the cell.

However, some terminal devices with limited capabilities exist besides some terminal devices with normal functions, such as NR lightweight (light) terminal devices, reduced capability (redcapability, REDCAP) terminal devices, enhanced machine type communication (eMTC) terminal devices, or narrowband internet of things (NB-IoT) terminal devices. For such terminal devices, in order to reduce the device complexity, the operating bandwidth and the number of receiving antennas need to be reduced, thereby resulting in bandwidth limitation, for example, the operating bandwidth of an NR light terminal device may be 5M, 10M or 20M. The NR light terminal device operating bandwidth may be smaller than the initial downlink BWP. Therefore, the network device sends the paging message on the resource of the initial downlink BWP, the terminal device with normal function can successfully receive the paging message, and coverage loss may be generated to some NR light terminal devices due to bandwidth limitation or reduction of receiving antennas, so that some NR light terminal devices may not hear the paging message (or system message) or cause lengthening of listening delay, thereby affecting subsequent downlink data transmission.

As can be seen from the above, the terminal device with limited bandwidth has a coverage recovery (coverage recovery) requirement. Applicants have found that there is gain in frequency hopping, for example, there may be a gain of 2-3 dB. If the paging message (or the system message) is sent by using a frequency hopping mode for the terminal device with limited bandwidth, such as an NR light terminal device, the gain of frequency hopping can meet the requirement of coverage recovery of the terminal device with limited bandwidth. However, in the current system, the sending of the paging message (or the system message) does not support the switching of frequency domain resources, such as the switching of BWP, so for the terminal device with limited bandwidth, how the network device supports sending the paging message (or the system message) in a frequency hopping manner is a problem to be solved.

Based on this, embodiments of the present application provide a communication method and apparatus, where a network side configures a transmission method, such as a frequency hopping method or a non-frequency hopping method, of a paging message (or a system message), so as to transmit the paging message (or the system message) according to the configured transmission method of the paging message (or the system message). The method for transmitting the paging message (or the system message) may also be referred to as a method for transmitting the paging message (or the system message). For example, the paging message (or the system message) is sent by using a frequency hopping method for the NR light terminal device, which can meet the requirement of coverage recovery of the terminal device.

It should be noted that there are many similarities between system messaging and paging messaging. For example, the paging message and the system message are common messages and are sent for all or a group of terminal devices. Therefore, the scheme provided by the application is also suitable for sending the system message, unless particularly stated. In the following description, a paging message is taken as an example for explanation.

The technical solution provided in the embodiment of the present application may be applied to the 4th generation (4G) system, such as a Long Term Evolution (LTE) system, or may be applied to a 5G system, such as an NR system, or may also be applied to a next generation mobile communication system or other similar communication systems, which is not limited specifically.

Please refer to fig. 1, which is an application scenario of the present application. Fig. 1 includes a network device, a core network device, and a terminal device 1. The network device and the terminal device 1 are capable of communication, for example, the network device may send a paging message to the terminal device 1. The terminal device 1 may be a bandwidth limited terminal device, such as an NR light terminal device. The terminal 1 may also be a terminal with unlimited bandwidth, or a common terminal. The core network device and the network device may be separate physical devices, or the function of the core network device and the logical function of the access network device may be integrated on the same physical device, or a physical device may be integrated with a part of the function of the core network device and a part of the function of the access network device. In fig. 1, a network device and a core network device are two independent devices as an example. Fig. 1 is a schematic diagram, and other network devices, such as a wireless relay device and a wireless backhaul device, may also be included in the communication system, which are not shown in fig. 1. The embodiments of the present application do not limit the number of core network devices, and terminal devices included in the mobile communication system.

The method provided by the embodiment of the application is described below with reference to the accompanying drawings.

Referring to fig. 2, a flowchart of a first communication method is provided in the embodiment of the present application. In the following description, the method is applied to the network architecture shown in fig. 1 as an example. For convenience of description, the method is performed as an example by the network device and the first terminal device. In the steps performed by the network device, for example, the chip or the chip system in the network device may be performed, and in the steps performed by the terminal device, for example, the chip or the chip system in the terminal device may be performed. The network device described below may be a network device in the network architecture shown in fig. 1, the first terminal device described below may be the terminal device 1 shown in fig. 1, and the second terminal device described below may be the terminal device 2 shown in fig. 1.

S201, a network device acquires first configuration information, wherein the first configuration information comprises first information, the first information is used for configuring a transmission mode of a paging message, and the transmission mode of the paging message is a frequency hopping mode or a non-frequency hopping mode.

In the embodiment of the present application, a network device sends a paging message to a first terminal device as an example, so a transmission manner of first information for configuring the paging message may also be described as a manner for configuring the network device to send the paging message, or a manner for configuring the first terminal device to receive the paging message. In addition, the mode of sending the paging message can also be described as the sending mode of the paging message, and the mode of receiving the paging message can also be described as the receiving mode of the paging message.

The first configuration information may be determined by the core network device and configured to the network device, and when the network device acquires the first configuration information, the network device may specifically receive the first configuration information sent by the core network device. For example, the core network device may carry the first configuration information in a paging message and send the paging message to the network device when sending the paging message of the first terminal device to the network device. Alternatively, the first configuration information may be configured to the network device by other devices in the network system. The first configuration information may be determined autonomously by the network device or configured in the network device by an administrator, or the first configuration information may be protocol-specified.

As a possible implementation manner, when the core network device or other network devices in the network system configure the transmission manner of the paging message to the network device through the first information, a configuration displaying method or an implicit configuration method may be adopted, that is, the configuration manner of the first information may adopt an explicit configuration method or an implicit configuration method.

In an example, taking the explicit configuration of the first information as an example, the first information may be an indication bit, for example, when the indication bit is a first value, the first information indicates that the transmission mode of the paging message is a frequency hopping mode, and when the indication bit is a second value, the first information indicates that the transmission mode of the paging message is a non-frequency hopping mode. For example, the first value is 1, and the second value is 0; or the first value is 0 and the second value is 1.

In another example, the first information is configured implicitly. The first information may include information of frequency domain resources used for transmitting the paging message. For example, the first information includes information of at least two frequency domain resources used for transmitting the paging message, that is, at least two frequency domain resources are configured for the network device, and implicitly indicates that the mode in which the network device sends the paging message is a frequency hopping mode. For another example, the first information includes information of a frequency domain resource used for transmitting the paging message, and implicitly indicates that the mode of sending the paging message by the network device is a non-frequency hopping mode. The information of the frequency domain resources includes at least location information of the frequency domain resources. The location information of the frequency domain resources may include one or more of frequency points, carriers, frequency bands, or bandwidths of the frequency domain resources.

The frequency domain resource may be BWP or narrowband. Such as BWP for frequency domain resources. Optionally, the information of the BWP may further include one or more of a subcarrier spacing (SCS) identification, a control resource set (coreset) identification, or a search space (searchspace) identification in addition to the position information of the BWP.

For example, the at least two BWPs may include an initial downlink BWP, a BWP where a control resource set (core resource set, core) #0 corresponding to another CD-SSB with a different frequency domain position of the cell definition synchronization signal block used by the first terminal device is located, or a BWP where a cell definition synchronization signal block used by the first terminal device is located. And the CORESET defines resources for transmitting control information. In the NR system, a terminal device resides in a cell defined by a CD-SSB, and listens to a control channel on a resource defined by COREST #0 to receive a paging message or a system message, etc. Therefore, the configured at least two BWPs may be BWPs including CORESET #0, and the configured frequency domain position may be the frequency domain position where CORESET #0 is located.

S202, the network device sends the paging message to the first terminal device according to the mode of sending the paging message configured by the first configuration information.

For example, the mode configured by the first configuration information for sending the paging message is a frequency hopping mode, and the network device may send the paging message in the frequency hopping mode. For another example, the mode configured by the first configuration information for sending the paging message is a non-frequency hopping mode, and the network device may send the paging message in the non-frequency hopping mode.

As a possible implementation manner, in a case that the core network device or other network devices in the network system configure the first information to the network device by using the method of display configuration, if the transmission mode configured for the paging message is a frequency hopping mode, the first information may further include location information of at least two frequency domain resources used for transmitting the paging message. In S202, the network device transmits a paging message in a frequency hopping manner on the at least two frequency domain resources according to the first information. Taking the first frequency domain resource and the second frequency domain resource as an example, the network device transmits the paging message by using the first frequency domain resource in the first time unit, and transmits the paging message by using the second frequency domain resource in the second time unit. It should be noted that, the core network device or other network devices in the network system may also separately configure the transmission mode of the paging message and the location information of the at least two frequency domain resources used for transmitting the paging message to the network device, for example, configure the transmission mode of the paging message and the location information of the at least two frequency domain resources used for transmitting the paging message to the network device through different messages.

The rule for determining the first configuration information by the core network device or the network device is, for example, to transmit the first configuration information in a non-frequency hopping manner for the terminal device in the center of the cell and to transmit the first configuration information in a frequency hopping manner for the terminal device of the user at the edge of the cell. Or, the terminal equipment of a specific service type transmits in a frequency hopping manner, or the terminal equipment of a special service type transmits in a frequency hopping manner.

As a possible implementation manner, when the first information included in the first configuration information indicates that the frequency hopping scheme is adopted, the first configuration information may include second information in addition to the first information. The first information and the second information may be used to jointly indicate that the paging message is transmitted in a frequency hopping manner for a particular type of terminal device. For example, the second information includes type information of a terminal device supporting the transmission of the paging message in the frequency hopping manner, or includes type information of a service supported by the terminal device, or includes the type information of the terminal device and the type information of the service supported by the terminal device. The type information of the terminal device may be used to determine whether the terminal device is a terminal device with limited bandwidth (i.e., a specific type of terminal device), that is, the network device determines, according to the type information of the terminal device, which terminal devices may transmit the paging message in a frequency hopping manner. For example, if the first configuration information includes the first information and the second information, the network device is instructed to adopt a frequency hopping mode for the terminal device indicated by the second information. And if the first configuration information does not comprise the second information, indicating that the network equipment can transmit the paging message by adopting a frequency hopping mode aiming at any type of terminal equipment. The types of the terminal devices include, for example, NR light terminal device types, eMTC terminal device types, NB-IoT terminal device types, and the like, and these types may be further subdivided, for example, the NR light terminal device types may further include mode (type)1 terminal devices, type2 terminal devices, and the like. The service types supported by the terminal device include, for example, an Industrial Wireless Sensor Network (IWSN) service type, a wearable type, a monitoring service type, and the like.

In the embodiment of the present application, it is referred to the first terminal device, and therefore if the second information includes the type information of the terminal device, the second information may include the type information of the first terminal device; similarly, if the second information includes the type information of the service supported by the terminal device, the second information may include the type information of the service supported by the first terminal device.

In the embodiment of the present application, in order to enable the first terminal device to determine whether to receive the paging message in the frequency hopping manner, the network device or the core network device instructs the terminal device whether to receive the paging message in the frequency hopping manner.

In a possible implementation manner, after the core network device sends the first configuration information to the network device, that is, after the network device receives the first configuration information from the core network device, the network device may send the first configuration information to the first terminal device.

In another possible implementation manner, the network device determines the first configuration information and sends the first configuration information to the first terminal device. For example, the first configuration information is determined autonomously by the network device or configured in the network device by an administrator, or the first configuration information is specified by a protocol.

When the network device sends the first configuration information to the first terminal device, the network device may send the first configuration information in any one of the following manners:

in one approach, the network device may broadcast the first configuration information via a system message. The first configuration information sent by the network device to the first terminal device includes first information. The first information is used for configuring a transmission manner of the paging message, and may be an implicit configuration or a display configuration, which is specifically described above.

In the case that the first information adopts the implicit configuration mode, the first configuration information configured by the network device to the first terminal device includes location information of at least two frequency domain resources for receiving the paging message. At least two frequency domain resources are configured for the first terminal device, and the mode of implicitly indicating the first terminal device to receive the paging message is a frequency hopping mode. For another example, the network device configures a frequency domain resource for the first terminal device to receive the paging message, and implicitly indicates that the manner in which the first terminal device receives the paging message is a non-frequency hopping manner.

The first configuration information broadcast by the network device may be for the terminal device group only, or for a specific type of terminal device, or for all terminal devices. For example, the first configuration information broadcast by the network device is for a terminal device group, and the first configuration information may further include a terminal device group identifier, where the terminal device group includes the first terminal device. Under the condition that the first information includes the location information of at least two frequency domain resources, the first configuration information may further include a terminal device group identifier, and the terminal devices belonging to the terminal device group may receive the paging message in a frequency hopping manner. For another example, the first configuration information broadcasted by the network device is for a specific type of terminal device, and the first configuration information may further include type information of the terminal device and/or a type of a service supported by the terminal device. The description of the type of the terminal device and the type of the service is as described above, and is not repeated here. In the case that the first information includes location information of at least two frequency domain resources, the terminal device that satisfies the type information (including the type of service and the type of terminal device) may receive the paging message in a frequency hopping manner. For another example, the first configuration information broadcasted by the network device is specific to all terminal devices, and the first configuration information may include location information of the at least two frequency domain resources, and no longer include a terminal device group identifier, type information of the terminal device, and/or a type of a service supported by the terminal device. And under the condition that the first information comprises the position information of at least two frequency domain resources, all the terminal equipment can receive the paging message in a frequency hopping mode.

It should be understood that, in the embodiment of the present application, it is said that the first configuration information is configured for the first terminal device, and therefore, if the first configuration information includes the terminal device group identifier, the first terminal device is included in the terminal device group. If the first configuration information includes type information of a service supported by the terminal device, the included may be type information of the service supported by the first terminal device. If the first configuration information includes type information of the terminal device, included may be the type information of the first terminal device.

In this case, after receiving the first configuration information, the first terminal device monitors the paging message in a frequency hopping manner on the at least two frequency domain resources according to the first configuration information. Of course, the first terminal device may also listen to the paging message in all or part of the at least two frequency domain resources.

Taking the example that the at least two frequency domain resources include a first frequency domain resource and a second frequency domain resource, the network device sends the paging message through the first frequency domain resource on the first time unit. The network device transmits the paging message over a second frequency domain resource on a second time unit. The first terminal device monitors the paging message through the first frequency domain resource in the first time unit, and monitors the paging message through the second frequency domain resource in the second time unit. In another possible mode, the first terminal device does not use a frequency hopping mode for monitoring, monitors the paging message through the first frequency domain resource and the second frequency domain resource in the first time unit, and monitors the paging message through the first frequency domain resource and the second frequency domain resource in the second time unit. Of course, if the paging message is monitored on the first frequency domain resource, the first terminal device may feed back to the network device, such as triggering an RRC procedure. After determining the feedback of the first terminal device, the network device does not send the paging message again through the second frequency domain resource in the second time unit.

It should be noted that the frequency hopping transmission of the paging message may be transmission of the paging message between different POs, and the first time unit and the second time unit may be different POs. Or may be transmitted between different PDCCH monitoring occasions (monitoring occasions) in the same PO, the first time unit and the second time unit may be different PDCCH monitoring occasions in one PO.

For example, in the NR scenario, a beam concept is introduced, where one PO includes multiple PDCCH monitoring sessions, one PDCCH monitoring session corresponds to one beam paging message, and different PDCCH monitoring sessions correspond to different beams, that is, one PDCCH monitoring session carrying a paging message is sent on one beam. If only one PDCCH monitoring session in one PO is used for paging message transmission of the beam for one beam, then the frequency hopping transmission of the paging message may be frequency hopping transmission of the paging message between different POs. If one beam is targeted, one PO includes a plurality of PDCCH monitoring sessions for paging message transmission of the beam. For example, in an NR-U scenario, in order to avoid a problem that a PDCCH monitoring occasion for a certain beam cannot send a paging message for the beam due to resource contention failure or resource sensing failure, a PO may include multiple PDCCH monitoring occasions for sending the paging message for the beam for the same beam. Then, at this time, the frequency hopping transmission of the paging message may be frequency hopping of the paging message between different PDCCH monitoring sessions in the same PO. Of course, even if a plurality of PDCCH monitoring sessions are included for the transmission of the paging message of the same beam within one PO, the frequency hopping transmission of the paging message may be the transmission of the paging message between different POs.

It should be noted that there are many similarities to paging message transmission with respect to frequency hopping transmission of system messages. The above mechanism is also suitable for the transmission of system messages. The network device may frequency hop between different system information windows (SI-windows), i.e., the first time unit and the second time unit may be different system message windows. Or, the paging message may be sent by frequency hopping between different PDCCH monitoring occasions (monitoring occasions) in the same information window, and the first time unit and the second time unit may be different PDCCH monitoring occasions in one system information window. The system message window may also be referred to as a system message reception window or a system message transmission window, such as for a network device, may be referred to as a system message transmission window, and for a terminal device, may be referred to as a system message reception window.

For example, in the NR system, one system message window includes multiple PDCCH monitoring sessions, one PDCCH monitoring session corresponds to one beam paging message transmission, and different PDCCH monitoring sessions correspond to different beams, that is, one PDCCH monitoring session carrying a paging message is transmitted on one beam.

In the NR system supporting multiple beams, the SI-window may include different PDCCH monitoring sessions, and one PDCCH monitoring session corresponds to the transmission of a beam system message. Then, the frequency hopping transmission of the system message may be transmission of the system message between different SI windows. Similarly, in the NR-U, in order to avoid the problem that the PDCCH monitoring interference for a certain beam cannot transmit the system message for the beam due to the failure of resource contention or the failure of resource sensing, one SI window includes multiple PDCCH monitoring interference for the same beam. In this case, the network device may frequency hop between different PDCCH monitoring sessions in the same SI window to send the system message. Of course, even if a plurality of PDCCH monitoring sessions are included in one SI window for transmitting the system message of the beam, the network device may frequency-hop the system message between different SI windows. The SI window is a system message sending window or a system message receiving window.

As an example, the PDCCH monitoring scheduling may be a monitoring slot, a transmission slot of a control channel, or other resources for transmitting the PDCCH. The control channel may be, for example, a machine communication physical downlink control channel (MPDCCH), a Narrowband Physical Downlink Control Channel (NPDCCH), or an enhanced physical downlink control channel (ePDCCH).

In another way, the network device may send the first configuration information by sending a dedicated message to the first terminal device. The dedicated message may be, for example, an RRC Release (Release) message. The first configuration information includes first information.

And under the condition that the first information adopts the display configuration, the first information comprises an indication bit. For example, when the indication bit is the first value, the first terminal device is indicated to receive the paging message in a frequency hopping manner. And when the indicating bit is a second value, indicating the first terminal equipment to receive the paging message in a non-frequency hopping mode. For example, the first value is 1, and the second value is 0; or the first value is 0 and the second value is 1.

In one case, in a case that the first terminal device is instructed to receive the paging message in a frequency hopping manner, the first information may further include information of at least two frequency domain resources configured for the first terminal device to receive the paging message in a frequency hopping manner.

In this case, after receiving the first configuration information, the first terminal device monitors the paging message in a frequency hopping manner on at least two frequency domain resources configured by the first configuration information. Of course, the first terminal device may also listen to the paging message in all or part of the at least two frequency domain resources.

Alternatively, at least the frequency domain resource for the bandwidth limited terminal device to frequency hop receive the paging message may also be specified by the protocol. Under the condition that the first terminal device is instructed to receive the paging message in the frequency hopping mode, the network device does not need to allocate the position information of at least two frequency domain resources for receiving the paging message in the frequency hopping mode for the first terminal device.

And under the condition that the first information adopts the implicit configuration, the first information comprises information of at least one frequency domain resource. For example, the first information includes information of at least two frequency domain resources for transmitting the paging message. At least two frequency domain resources are configured for the first terminal device, and the mode of implicitly indicating the first terminal device to receive the paging message is a frequency hopping mode. For another example, the network device configures a frequency domain resource for transmitting the paging message to the first terminal device, and implicitly indicates that the mode in which the terminal device receives the paging message is a non-frequency hopping mode.

In another possible implementation manner, the core network device sends information for configuring a sending manner of the paging message to the first terminal device. In order to distinguish from the first configuration information, the configuration information of the transmission method of the paging message configured by the core network device to the first terminal device is referred to as second configuration information. It should be understood that, the core network device sends the second configuration information to the first terminal device, which may be that the core network device sends the second configuration information to the network device through an N1 interface message, and the network device transparently transmits the N1 interface message to the first terminal device.

The second configuration information includes fourth information, and the fourth information is used for configuring a transmission mode of the paging message. The configuration mode of the fourth information is similar to that of the first information, and an implicit configuration mode or a display configuration mode can be adopted.

In an example, taking the explicit configuration of the fourth information as an example, the fourth information may include an indication bit, for example, when the indication bit is a first value, the fourth information indicates that the transmission mode of the paging message is a frequency hopping mode, and when the indication bit is a second value, the fourth information indicates that the transmission mode of the paging message is a non-frequency hopping mode. For example, the first value is 1, and the second value is 0; or the first value is 0 and the second value is 1.

In another example, the fourth information is implicitly configured. The fourth information may include frequency domain resources for the terminal device to receive the paging message. For example, the fourth information includes information of at least two frequency domain resources for the first terminal device to receive the paging message in a frequency hopping manner. At least two frequency domain resources are configured for the first terminal device, and the mode of implicitly indicating the terminal device to receive the paging message is a frequency hopping mode. For another example, the fourth information includes a frequency domain resource for the first terminal device to receive the paging message, and implicitly indicates that the manner in which the first terminal device receives the paging message is a non-frequency hopping manner.

As a possible implementation manner, in a case that the core network device configures the fourth information to the first terminal device by using the display configuration method, if the transmission mode configured for the paging message is a frequency hopping mode, the fourth information may further include location information of at least two frequency domain resources used for transmitting the paging message. Taking the first frequency domain resource and the second frequency domain resource as an example, the network device transmits the paging message by using the first frequency domain resource in the first time unit, and transmits the paging message by using the second frequency domain resource in the second time unit. It should be noted that, the core network device may further separately configure the transmission mode of the paging message and the location information of the at least two frequency domain resources used for transmitting the paging message to the first terminal device, for example, configure the transmission mode of the paging message and the location information of the at least two frequency domain resources used for transmitting the paging message to the first terminal device through different messages.

The rule for determining the second configuration information by the core network device is, for example, to transmit the second configuration information by using a non-frequency hopping manner for the terminal device in the center of the cell and to transmit the second configuration information by using a frequency hopping manner for the terminal device of the user at the edge of the cell. Or, the terminal equipment of a specific service type transmits in a frequency hopping manner, or the terminal equipment of a special service type transmits in a frequency hopping manner.

As a possible implementation manner, in the case that the fourth information included in the second configuration information indicates that the frequency hopping scheme is adopted, the second configuration information may include fifth information in addition to the fourth information. The fourth information and the fifth information may be used to jointly instruct a specific type of terminal device to receive the paging message in a frequency hopping manner. For example, the fifth information includes type information of a terminal device supporting the transmission of the paging message in the frequency hopping manner, or includes type information of a service supported by the terminal device, or includes the type information of the terminal device and the type information of the service supported by the terminal device. The type information of the terminal device may be used to determine whether the terminal device is a terminal device with limited bandwidth (i.e., a terminal device of a specific type), that is, the terminal device determines whether to receive the paging message in a frequency hopping manner according to the type information of the terminal device. For example, if the second configuration information includes the fourth information and the fifth information, it is indicated that the paging message is received in a frequency hopping manner for the terminal device indicated by the fifth information. And if the second configuration information does not include the fifth information, the paging message can be received in a frequency hopping manner for any type of terminal device.

As an optional implementation manner, the first terminal device may send, according to its own requirement, indication information to the network device or the core network device, where the indication information is used to indicate that the first terminal device expects to receive a paging message in a frequency hopping manner. The network device or the core network device may determine whether to transmit the paging message in a frequency hopping manner for the first terminal device according to the indication information transmitted by the first terminal device. And if the paging message is determined to be sent in a frequency hopping mode, allocating at least two frequency domain resources for receiving the paging message for the first terminal equipment. If the network device has sent the first configuration information for the first terminal device, or the core network device has sent the second configuration information for the first terminal device, after receiving the indication information, at least two frequency domain resources may not be allocated to the first terminal device any more.

In one mode, the first terminal device may send the indication information to the network device or the core network device through the auxiliary information. I.e. the auxiliary information comprises said indication information.

In another mode, the first terminal device may send the indication information to the network device or the core network device through a Tracking Area (TA) update message or a radio access network area (RA) update message, where the indication information is carried in the tracking area update message.

As an example, the first terminal device may send the indication information to the network device when determining that its own path loss reaches the threshold.

In a possible scenario, a mode of sending a paging message by a network device is a frequency hopping mode, and when the network device determines that the number of times of sending the paging message to the first terminal device reaches a first threshold value, the network device sends the paging message to the first terminal device through the at least two frequency domain resources in a non-frequency hopping mode; or, when it is determined that the time length for sending the paging message to the first terminal device reaches a second threshold, sending the paging message to the first terminal device through the at least two frequency domain resources in a non-frequency hopping manner.

Taking the example that the at least two frequency domain resources include a first frequency domain resource and a second frequency domain resource, the network device sends the paging message through the first frequency domain resource on the first time unit. The network device transmits the paging message over a second frequency domain resource on a second time unit. If the number of times of sending the paging message to the first terminal device is determined to reach the first threshold and the feedback of the first terminal device is not received, the paging message may be sent to the first terminal device through the first frequency domain resource and the second frequency domain resource in the third time unit. Alternatively, if it is determined that the time length for sending the paging message to the first terminal device reaches the second threshold (for example, the time length of X POs) and the feedback of the first terminal device is not received, the paging message may be sent to the first terminal device through the first frequency domain resource and the second frequency domain resource in the third time unit.

When the communication device is a terminal device, fig. 4 shows a simplified structural diagram of the terminal device. For easy understanding and illustration, in fig. 4, the terminal device is exemplified by a mobile phone. As shown in fig. 4, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input-output device. The processor is mainly used for processing communication protocols and communication data, controlling the terminal equipment, executing software programs, processing data of the software programs and the like. The memory is used primarily for storing software programs and data. The radio frequency circuit is mainly used for converting baseband signals and radio frequency signals and processing the radio frequency signals. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are used primarily for receiving data input by a user and for outputting data to the user. It should be noted that some kinds of terminal devices may not have input/output devices.

When data needs to be sent, the processor performs baseband processing on the data to be sent and outputs baseband signals to the radio frequency circuit, and the radio frequency circuit performs radio frequency processing on the baseband signals and sends the radio frequency signals to the outside in the form of electromagnetic waves through the antenna. When data is sent to the terminal equipment, the radio frequency circuit receives radio frequency signals through the antenna, converts the radio frequency signals into baseband signals and outputs the baseband signals to the processor, and the processor converts the baseband signals into the data and processes the data. For ease of illustration, only one memory and processor are shown in FIG. 4. In an actual end device product, there may be one or more processors and one or more memories. The memory may also be referred to as a storage medium or a storage device, etc. The memory may be provided independently of the processor, or may be integrated with the processor, which is not limited in this embodiment.
