For example, on the one hand, the wake-up accuracy of the terminal device can be improved, so that the increase in power consumption caused by false wake-up can be avoided, and the communication problem caused by delayed wake-up can be avoided; on the other hand, the MR receiving performance, such as the accuracy of RRM measurement and the accuracy of CSI-RS measurement, can be improved.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] When a terminal device receives a paging message in an idle or inactive state, and when it receives data in a connected state, it uses the same receiving module, which can be called the main receiver.

[0003] To further reduce the power consumption of terminal devices, a separate low-power circuit can be used to receive paging-related messages. This circuit can be called a wake-up circuit, and the signal received by the wake-up circuit can be called a wake-up signal.

[0004] In some scenarios, it may be necessary for the main receiver and the wake-up circuit to receive signals simultaneously. Examples include when a terminal device receives a wake-up signal and uses the main receiver for radio resource measurements based on synchronization blocks, or when a terminal device receives a wake-up signal and uses the main receiver for channel-state information reference signal (CSI-RS) measurements. Because the main receiver and the wake-up circuit share some receiving hardware, simultaneous reception by both can cause conflicts. Summary of the Invention

[0005] This application provides a communication method and apparatus to resolve the problem of reception conflict between the main receiver and the wake-up circuit.

[0006] In a first aspect, a communication method is provided. The execution subject of the method may be a terminal device or a chip, chip system or circuit for the terminal device. The method can be implemented through the following steps: sending first capability information of the terminal device, the first capability information including first information, the first information indicating the wake-up signal capability of the first frequency band in the first frequency band combination.

[0007] In this application, the terminal device's ability to wake up the signal when reporting the frequency band combination configuration helps to avoid conflicts between the wake-up signal and the main receiver. For example, on the one hand, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0008] Secondly, a communication method is provided. The execution subject of the method can be a network device or a chip, chip system or circuit used in the network device. The method can be implemented through the following steps: receiving first capability information of a terminal device, the first capability information including first information, the first information indicating the wake-up signal capability of the first frequency band in the first frequency band combination.

[0009] In this application, the terminal device's ability to wake up the signal when reporting the frequency band combination configuration helps to avoid conflicts between the wake-up signal and the main receiver. For example, on the one hand, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0010] Based on the first and second aspects mentioned above, the following design is possible:

[0011] In one possible design, the wake-up signal capability includes whether it supports simultaneous reception of the wake-up signal and the main receiver. This design helps avoid conflicts between the wake-up signal and the main receiver's reception.

[0012] In one possible design, the first capability information includes first information, which includes: the first capability information includes capability information of a first frequency band combination, the capability information of the first frequency band combination includes a feature set of the first frequency band, and the feature set includes the first information. This design, by carrying the first information through the feature set of the first frequency band, can indicate the ability of the wake-up signal and the main receiver in the first frequency band combination to receive simultaneously, which helps to avoid conflicts between the wake-up signal and the main receiver's reception.

[0013] In one possible design, the capability information for the first frequency band combination also includes the frequency band parameters of the first frequency band when configuring the wake-up signal. This design avoids downlink reception exceeding the capabilities of the terminal device.

[0014] In one possible design, the capability information of the first frequency band combination includes N frequency band parameters of the first frequency band, where N is an integer greater than 0, and one of the N frequency band parameters is used to configure the wake-up signal.

[0015] In one possible design, the first capability information also includes capability information for a second frequency band combination, where the frequency bands included in the second frequency band combination are the same as those included in the first frequency band combination. The capability information for the second frequency band combination includes the frequency band parameters of the first frequency band when no wake-up signal is configured. By reporting the capability information of the first frequency band combination when no wake-up signal is configured, it is beneficial to ensure the rationality of the component carrier (CC) configuration of network devices and improve communication performance.

[0016] In one possible design, the capability information of the second frequency band combination includes N+1 frequency band parameters of the first frequency band, where N is an integer greater than 0.

[0017] In one possible design, the capability information of the first frequency band combination also includes the frequency band parameters of the first frequency band when no wake-up signal is configured. By reporting the capability information of the first frequency band combination in the form of reporting the capabilities of the first frequency band combination when a wake-up signal is configured and the capabilities when no wake-up signal is configured, the reporting overhead can be reduced.

[0018] In one possible design, the first capability information includes first information, which includes: the first capability information includes capability information of a first frequency band combination, the capability information of the first frequency band combination includes first frequency band parameters of the first frequency band, and the first frequency band parameters include the first information. By reporting the first information in the frequency band parameters, the reporting overhead can be reduced.

[0019] In one possible design, only one frequency band in the first frequency band combination is configured with a wake-up signal.

[0020] Thirdly, a communication method is provided. The execution subject of the method can be a terminal device or a chip, chip system or circuit for the terminal device. The method can be implemented through the following steps: if the first monitoring time of the wake-up signal and the first measurement time of the downlink signal overlap in M ​​first time units, then it is determined that the wake-up signal will not be received in the M first time units. The downlink signal includes a synchronization signal block and / or a downlink reference signal.

[0021] This application addresses the conflict between the wake-up signal and the main receiver by configuring the monitoring timing of the wake-up signal to avoid the first measurement timing of the downlink signal. This helps to avoid the conflict between the wake-up signal and the main receiver. For example, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0022] In one possible design, the method further includes receiving the wake-up signal in M ​​second time units after the first measurement. This approach helps ensure sufficient time-domain resources for the wake-up signal, improves the wake-up accuracy of the terminal device, and avoids both increased power consumption due to false wake-ups and communication problems caused by delayed wake-ups.

[0023] In one possible design, the time unit is a symbol or a time slot.

[0024] Fourthly, a communication method is provided. The execution subject of the method can be a network device or a chip, chip system or circuit used in the network device. The method can be implemented through the following steps: if the first monitoring timing of the wake-up signal and the first measurement timing of the downlink signal overlap in M ​​first time units, then the wake-up signal is not sent in the M first time units.

[0025] This application addresses the conflict between the wake-up signal and the main receiver by configuring the monitoring timing of the wake-up signal to avoid the first measurement timing of the downlink signal. This helps to avoid the conflict between the wake-up signal and the main receiver. For example, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0026] In one possible design, the method further includes receiving the wake-up signal in M ​​second time units after the first measurement. This approach helps ensure sufficient time-domain resources for the wake-up signal, improves the wake-up accuracy of the terminal device, and avoids both increased power consumption due to false wake-ups and communication problems caused by delayed wake-ups.

[0027] In one possible design, the time unit is a symbol or a time slot.

[0028] Fifthly, a communication method is provided. The execution subject of the method can be a terminal device or a chip, chip system or circuit for the terminal device. The method can be implemented through the following steps: if the second monitoring time of the wake-up signal overlaps with the second measurement time of the downlink signal, the wake-up signal is not received during the second monitoring time. The downlink signal includes a synchronization signal block and / or a downlink reference signal.

[0029] This application addresses the conflict between the wake-up signal and the main receiver by configuring the monitoring timing of the wake-up signal to avoid the first measurement timing of the downlink signal. This helps to avoid the conflict between the wake-up signal and the main receiver. For example, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve MR reception performance, such as the accuracy of RRM measurement and CSI-RS measurement.

[0030] In one possible design, the method further includes: if the number of monitoring opportunities that do not overlap with the downlink signal measurement opportunity in the wake-up signal monitoring opportunity is greater than or equal to a threshold, then whether to wake up is determined based on the wake-up signal on the monitoring opportunity that does not overlap with the downlink signal measurement opportunity; if the number of monitoring opportunities that do not overlap with the downlink signal measurement opportunity in the wake-up signal monitoring opportunity is less than or equal to the threshold, then wake-up is determined. This design can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption due to false wake-ups and communication problems caused by delayed wake-ups. It can also improve the receiving performance of the main receiver, such as the accuracy of RRM measurements and CSI-RS measurements.

[0061] The technical solutions provided in the embodiments of this application can be applied to various wireless communication systems. For example, the methods provided in the embodiments of this application can be applied to communication systems related to the 3rd Generation Partnership Project (3GPP), such as Long Term Evolution (LTE) communication systems, 5th Generation (5G) mobile communication systems, or other next-generation mobile communication systems, such as 6th Generation (6G) communication systems, or other similar communication systems. Other similar communication systems may include Wireless Fidelity (WIFI), Vehicle-to-Everything (V2X), Internet of Things (IoT) systems, Narrow Band Internet of Things (NB-IoT) systems, and so on.

[0062] Please see Figure 1 This illustrates a network architecture for a communication system, which may include at least one network device and at least one terminal device. Figure 1Taking at least one terminal device as an example and at least one network device as an example, the network device can be an access network device, or the network device can include both access network devices and core network devices. Figure 1 The network architecture shown is merely illustrative; the number of terminal devices and / or network devices may be fewer or more. The communication systems described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application and do not constitute a limitation on the communication systems to which the embodiments of this application are applicable. Those skilled in the art will understand that, with the evolution of network architectures, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems. When applying the technical solutions of the embodiments of this application to other communication systems, the devices, components, modules, etc., in the embodiments can be replaced with corresponding devices, components, modules, etc., in other communication systems, without limitation.

[0063] The network devices involved in the embodiments of this application are mainly access network devices. Therefore, unless otherwise specified, the term "network device" in the following text refers to radio access network (RAN) devices, which can be simply referred to as access network devices. RAN can be a 3GPP-related cellular system, such as a 5G mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a virtualized RAN (vRAN), etc. RAN can also be a communication system that integrates two or more of the above systems. RAN devices can also be called RAN nodes, RAN entities, or access nodes, etc.

[0064] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. A RAN node can also be a macro base station, a micro base station, an indoor station, a relay node, a donor / host node, or a radio controller. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, a RAN node can be a roadside unit (RSU).

[0065] In another possible scenario, a RAN node can be a module or unit that performs some of the functions of a base station; or multiple RAN nodes can collaborate to assist terminal devices in achieving wireless access, with different RAN nodes performing some of the functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). The functions of a CU can be implemented by a single entity or by different entities. For example, the functions of a CU can be further divided, separating the control plane and the user plane and implementing them through different entities, namely the control plane CU entity (i.e., CU-control plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity). This CU-CP entity and CU-UP entity can be coupled with a DU to jointly complete the functions of the RAN node. The CU and DU can be set up separately or included in the same network element, such as in a baseband unit (BBU).

[0066] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0067] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (e.g., the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of protocol layers below the PDCP layer (e.g., the Radio Link Control (RLC) layer, the MAC layer, and / or the Physical (PHY) layer). For specific descriptions of the above-mentioned protocol layers, please refer to the relevant 3GPP technical specifications or the technical specifications of other applicable communication protocols. The above division of the processing functions of the CU and DU according to protocol layers is merely an example; other division methods are also possible, and this application does not impose any limitations.

[0068] Figure 2 An example diagram of an O-RAN system is shown. It should be understood that an O-RAN system may also include... Figure 2 Other components besides those shown are not specifically limited here. For example... Figure 2As shown, access network equipment can communicate with the core network (CN) via a backhaul link and with terminal equipment via an air interface. For example, access network equipment may include a baseband unit (BBU) and a radio unit (RU). The BBU includes at least one core unit (CU) and at least one dual unit (DU), which can communicate via at least one midhaul link. The RU can implement lower physical layer (PHY) and radio frequency (RF) functions. In some examples, the RU may be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the low-PHY may include PHY processing functions such as fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), digital beamforming, and filtering. The BBU can communicate with the CN via a backhaul link, and the RU can communicate with at least one terminal device via an air interface. The BBU can communicate with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0069] Figure 3 This diagram illustrates the network element functional division and protocol layer structure of an O-RAN device. It should be noted that... Figure 3 The configurations of the CU and DU shown are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only partial protocol layer processing functions. The DU and RU can be co-located or not. The DU and RU can exchange control plane and user plane information via a lower-layer split CUS-plane (LLS-CUS) interface through a fronthaul link. LLS-CUS may include LLS-C and LLS-U interfaces that provide the control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via an LLS-M interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0070] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0071] In the embodiments of this application, the means for implementing the functions of the network device can be the network device itself, or it can be a means that supports the network device in implementing the functions, such as a chip system or a combination of devices or components that can implement the functions of the network device. This means can be installed in the network device. The embodiments of this application do not limit the specific technology or specific device form used in the network device.

[0072] In this application embodiment, any device capable of data communication with a base station can be considered a terminal device. Terminal devices are also called terminals, user equipment (UE), mobile stations, or mobile terminals. Terminal devices can be widely used in various scenarios, such as D2D communication, V2X communication, machine-type communication (MTC), IoT, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, or smart cities. For example, terminal devices can be: mobile phones, computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, robotic arms, cameras, robots, or smart home devices (such as televisions, air conditioners, robot vacuums, speakers, set-top boxes), relays, customer premises equipment (CPE), etc.

[0073] The various terminal devices described above, if located on a vehicle (e.g., placed / installed inside the vehicle), can all be considered in-vehicle terminal devices. In-vehicle terminal devices can be built into a vehicle's in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit as one or more components or units. The vehicle can implement the methods of this application through the built-in in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit. In-vehicle terminal devices can be vehicle equipment, in-vehicle modules, vehicles, on-board units (OBU), roadside units (RSU), telematics boxes (T-boxes), chips, or systems on chips (SOCs), etc. These chips or SOCs can be installed in vehicles, OBUs, RSUs, or T-boxes.

[0074] In the embodiments of this application, the device for implementing the functions of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device in implementing the functions, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device. This device can be installed in the terminal device. The embodiments of this application do not limit the specific technology or specific device form used in the terminal device.

[0075] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0076] To facilitate understanding of the solution, the technical terms used in this application will be introduced below.

[0077] (1) UE capabilities

[0078] In order to better serve terminal devices, network devices need to know the capabilities of the terminal devices in order to configure and schedule them.

[0079] The capabilities of terminal devices can be divided into several levels. For example, such as... Figure 4 As shown, this hierarchical structure represents the structure of the terminal device's capability information. The terminal device's capability information may include:

[0080] - UE-specific capability information (also known as UE-level capabilities, per-UE capabilities, or UE capabilities): Applicable to all frequency bands and combinations thereof. UE-specific capability information includes capabilities supported by the UE across all frequency bands. UE-specific capabilities may include one or more of the following: access stratum release, PDCP parameters, etc.

[0081] - Band-specific capability information (also known as band-level capability, per-band capability, or frequency band capability): This is typically related to the radio frequency (RF) capabilities of a terminal device. Band-specific capability information includes the terminal device's capabilities on a specific frequency band. This capability may differ across different frequency bands. Band-specific capabilities may include the band identifier (FreqBandIndicatorNR), MIMO parameters (mimo-ParametersPerBand), etc. The terminal device's band-specific capability information may be included in the supported band list. The band list includes at least one frequency band supported by the terminal device. The band identifier indicates the frequency band corresponding to the band-specific capability information.

[0082] - Band combination (BC) specific capability information (also known as band combination-level capability, per BC capability, or band combination capability): This capability is related to band combinations, which are mainly associated with the carrier aggregation (CA) and DC capabilities supported by the terminal equipment. A band combination can consist of one or more bands and the carriers included in those bands that the terminal equipment supports for carrier aggregation or dual connectivity. In other words, for a band combination reported by a terminal equipment, the network equipment can configure the carriers included in that band combination for that terminal equipment to perform carrier aggregation or dual connectivity transmission. Furthermore, from a capability signaling structure perspective, the capabilities of a single band or a single carrier can also be reported through the signaling structure of a band combination. The band combination specific capability information of the terminal equipment can be included in the supported band combination list.

[0083] The band combination list contains at least one band combination supported by the terminal device. Each band combination may include band list, CA parameters (ca-ParametersNR), feature set combination identifier (FeatureSetCombinationId), and other band combination-specific capability information. The band list contains the bands that make up the band combination, and may include band parameters for the bands that make up the band combination. The parameters for each band may include one or more sets of consecutive component carriers (CCs) (also referred to as carriers).

[0084] Each frequency band combination can also be associated with a feature set combination (FSC), which can be identified by the feature set combination identifier. The FSC contains capability information for each frequency band in the frequency band combination (per band per BC capability or band / BC capability). The feature set in the FSC corresponds one-to-one with (or is associated with) the frequency band parameters in the list of combinations.

[0085] The per-band per-BC capability refers to the capability specific to a frequency band within a frequency band combination. Each frequency band in a frequency band combination can be associated with one or more feature sets (FS). Terminal devices can report the combination of per-band per-BC capabilities for a frequency band combination by reporting one or more feature sets. Figure 5 This illustration demonstrates a capability signaling structure that uses multiple feature sets to report different capabilities (e.g., per CC capability and / or per band per BC capability) for a frequency band combination. Each feature set includes a downlink feature set (FeatureSetDownlink) information element (IE) for reporting downlink transmission capabilities and an uplink feature set (FeatureSetUplink) information element for reporting uplink transmission capabilities, indicating the uplink and downlink transmission capabilities of the terminal device, respectively. Per band per BC capability can also be referred to as a frequency band feature set. The downlink feature set can indicate downlink intra-band frequency separation, downlink carrier feature set identifier, etc. The uplink feature set can indicate uplink carrier feature set identifier, etc.

[0086] Per CC capability refers to the capability of carriers within a frequency band in a frequency band combination. Per CC capability information can be expressed in the form of a carrier list. Each carrier is associated with a carrier feature set (FeatureSetPerCC, FSPC). The FSPC indicates the capability of the corresponding carrier, including, for example, the subcarrier spacing (SCS) supported by that carrier. Each FSPC includes downlink carrier feature set (FeatureSetDownlinkPerCC) cells for reporting downlink transmission capability and uplink carrier feature set (FeatureSetUplinkPerCC) cells for reporting uplink transmission capability, indicating the uplink and downlink transmission capabilities of the terminal equipment, respectively. Per CC capability can also be referred to as a carrier feature set.

[0087] The technical background of this application is described below.

[0088] When a terminal device receives a paging message in idle or inactive mode, and when it receives data in connected mode, it uses the same receiving module, which can be called the main receiver (MR). The main receiver can also be called the main radio (MR), MR receiver, etc. The following description uses the main receiver as an example. To further reduce the power consumption of the terminal device, a separate low-power circuit can be used to receive paging-related messages. This circuit can be called the wake-up radio (WUR), and the signal received by the wake-up radio can be called the wake-up signal (WUS). The wake-up radio can also be called a low-power wake-up radio (LP-WUR), wake-up receiver, low-power wake-up receiver, WUR receiver, LP-WUR receiver, WUS receiver, low-power circuit, etc. The following description uses the wake-up circuit as an example. The wake-up signal can also be called a low-power wake-up signal (LP-WUS), etc. The following description uses the wake-up signal as an example. Using a wake-up circuit to receive a wake-up signal can also be described as "operating on a wake-up receiving link (or low-power wake-up receiving link, WUR link, LP-WUR link, etc.)". The main receiver and wake-up circuit can be as follows: Figure 6 As shown.

[0089] In some scenarios, simultaneous reception by the main receiver and the wake-up circuit may be necessary. Examples include conflicts between WUS reception by the terminal device and radio resource management (RRM) measurements based on synchronization signal blocks (SSBs), or conflicts between WUS reception by the terminal device and channel-state information reference signal (CSI-RS) measurements. Since the main receiver and the wake-up circuit share some receiving hardware, simultaneous reception by both can lead to conflicts.

[0090] Based on this, embodiments of this application provide a communication method and apparatus to resolve the problem of conflict arising from simultaneous reception by the main receiver and the wake-up circuit. The method and apparatus are based on the same inventive concept. Since the principles underlying the problem-solving are similar, implementations of the apparatus and method can be mutually referenced, and repeated details will not be elaborated further.

[0091] In the embodiments of this application, "when," "if," and "if" all refer to the device taking corresponding actions under certain objective circumstances, and are not time-limited, nor do they require the device to perform a judgment action, nor do they imply any other limitations. Unless otherwise specified, "if" and "if" can be substituted, and "when" and "in the case of" can be substituted. "When" and "if" / "if" can be substituted.

[0092] In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and / or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0093] Furthermore, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the size, content, order, timing, priority, or importance of multiple objects.

[0094] It should be noted that the names of information elements, fields, containers, lists, and information in this application are merely exemplary names.

[0095] In this application, the basic capability information is merely a euphemism for some capability information, and this application does not limit the name of the capability information.

[0096] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. In the embodiments of this application, the executing entity can be a terminal device, a network device, or a chip, chip system, or circuit used in a terminal device or network device. The following description uses a terminal device or network device as the executing entity. When the executing entity is a chip, chip system, or circuit used in a terminal device or network device, receiving / transmitting can be understood as input / output. Furthermore, the processing performed by a single executing entity can also be divided into multiple executing entities, which can be logically and / or physically separated. For example, the processing performed by a network device can be divided into at least one of CU, DU, RU, etc.

[0097] Example 1:

[0098] In this application, the terminal device reports the wake-up signal capability of the first frequency band in the first frequency band combination to the network device through the terminal device's first capability information. This method helps to avoid the conflict between the wake-up signal and the main receiver receiving it at the same time. For example, on the one hand, it can improve the wake-up accuracy of the terminal device, thereby avoiding the increase in power consumption caused by false wake-up and the communication problems caused by delayed wake-up. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0099] like Figure 7 The diagram shown is a flowchart illustrating a communication method provided in an embodiment of this application.

[0100] S701: The terminal device sends the first capability information. Correspondingly, the network device receives the first capability information.

[0101] The first capability information includes first information indicating the wake-up signal capability of the first frequency band in the first frequency band combination. For example, the wake-up signal capability may include whether it supports simultaneous reception of the wake-up signal and the main receiver. Optionally, the wake-up signal capability may further include whether it supports the wake-up signal.

[0102] S702, network devices determine configuration information based on the first capability information.

[0103] As an example, after receiving the first capability information, the network device learns that the terminal device can receive the wake-up signal in the first frequency band, and then configures the carrier corresponding to a frequency band parameter of the first frequency band to send the wake-up signal through the configuration information.

[0104] Optionally, the network device may configure the carriers received by the main receiver on other frequency bands in the first frequency band combination according to the capabilities reported by the terminal device, and configure the carriers received by the main receiver on carriers corresponding to the parameters of other frequency bands in the first frequency band.

[0105] In S703, the network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information.

[0106] It should be noted that S702 and S703 are optional steps.

[0107] The following describes three ways in which the first capability information includes the first information, that is, three ways in which the first capability information indicates the wake-up signal capability of the first frequency band in the first frequency band combination.

[0108] Method 1 The first information is carried in the feature set of the first frequency band. That is, the first capability information includes the capability information of the first frequency band combination, the capability information of the first frequency band combination includes the feature set of the first frequency band, and the feature set includes the first information.

[0109] In one exemplary embodiment, the first information is carried in a feature set corresponding to a frequency band parameter (hereinafter referred to as frequency band parameter A) in the first frequency band.

[0110] In one implementation, the capability information of the first frequency band combination further includes the frequency band parameters of the first frequency band when configuring the wake-up signal. For example, the capability information of the first frequency band combination includes N frequency band parameters of the first frequency band, where N is an integer greater than 0, and one of the N frequency band parameters (i.e., frequency band parameter A) is used to configure the wake-up signal.

[0111] Optionally, the value of N can be less than the number of frequency band parameters supported by the first frequency band. For example, N can be equal to the number of frequency band parameters supported by the first frequency band minus 1. Since the wake-up signal requires a dedicated channel for reception, reporting one less set of consecutive CC signals can prevent downlink reception from exceeding the capabilities of the terminal device.

[0112] As one possible approach, if the first information indicates that the wake-up signal and the master receiver can be received simultaneously, the network device can configure continuous CCs corresponding to the first frequency band, and can also configure the wake-up signal on the continuous CCs corresponding to the first frequency band. For example, N sets of continuous CCs can be configured according to N frequency band parameters, and the master receiver can be configured to receive on the continuous CCs corresponding to the N frequency band parameters, and the wake-up signal can be configured on the continuous CCs corresponding to frequency band parameter A.

[0113] If the first information indication does not support simultaneous reception of the wake-up signal and the master receiver, the network device cannot configure the master receiver to receive on the continuous CC with the wake-up signal configured in the first frequency band. The network device can configure the continuous CC according to other frequency band parameters of the first frequency band and configure the master receiver to receive on the continuous CC. For example, it can configure N groups of continuous CC according to N frequency band parameters, configure the wake-up signal on the continuous CC corresponding to frequency band parameter A, and configure the master receiver to receive on the continuous CC corresponding to N-1 frequency band parameters other than frequency band parameter A.

[0114] Optionally, the network device can also configure continuous CCs corresponding to other frequency bands included in the first frequency band combination. For example, it can configure continuous CCs corresponding to other frequency bands according to the frequency band parameters of other frequency bands, and configure the main receiver to receive on the continuous CCs.

[0115] Optionally, the terminal device can also report the capability information of the first frequency band combination when no wake-up signal is configured. For example, the first capability information also includes the capability information of the second frequency band combination, which includes the same frequency bands as the first frequency band combination; the capability information of the second frequency band combination includes the frequency band parameters of the first frequency band when no wake-up signal is configured, for example, the capability information of the second frequency band combination includes N+1 frequency band parameters of the first frequency band.

[0116] The following uses the NR band (78) as an example to introduce the first capability information, assuming that the first band supports 3 consecutive CCs. The first capability information includes the capability information of the first band combination and the capability information of the second band combination. The first band combination and the second band combination include the same frequency bands. The capability information of the first band combination is the capability information of the first band combination when configuring the wake-up signal, such as... Figure 8 As shown. The capability information of the second frequency band combination is the capability information of the first frequency band combination when no wake-up signal is configured, such as... Figure 9 As shown.

[0117] The capability information of the first frequency band combination includes two frequency band parameters (i.e., frequency band parameter 1 and frequency band parameter 2) and a feature set corresponding to frequency band parameter 1 of the first frequency band. Optionally, it may also include a feature set corresponding to frequency band parameter 2. Each frequency band parameter is used to configure a set of consecutive CCs. The feature set corresponding to frequency band parameter 1 of the first frequency band carries first information to indicate whether the first frequency band supports simultaneous reception of wake-up signals and the main receiver; optionally, it may also indicate support for wake-up signals. The capability information of the second frequency band combination includes three frequency band parameters of the first frequency band and may also include feature sets corresponding to each of these three frequency band parameters. Each frequency band parameter is used to configure a set of consecutive CCs.

[0118] Method 2Similar to Method 1, the first information is carried in the feature set of the first frequency band. That is, the first capability information includes the capability information of the first frequency band combination, the capability information of the first frequency band combination includes the feature set of the first frequency band, and the feature set includes the first information.

[0119] The difference between Method 2 and Method 1 is that Method 1 reports the capabilities of the first frequency band combination when a wake-up signal is configured and when no wake-up signal is configured by reporting the capability information of two frequency band combinations, while Method 2 reports the capabilities of the first frequency band combination when a wake-up signal is configured and when no wake-up signal is configured by reporting the capability information of one frequency band combination, which can reduce the reporting overhead.

[0120] In one implementation, the capability information of the first frequency band combination also includes the frequency band parameters of the first frequency band when no wake-up signal is configured. For example, the capability information of the first frequency band combination includes N+1 frequency band parameters of the first frequency band. The value of N can be found in the relevant description in Method 1.

[0121] As one possible approach, if the first information indicates that simultaneous reception of the wake-up signal and the master receiver is not supported, or if the first information indicates that simultaneous reception of the wake-up signal and the master receiver is disabled (e.g., the first information is OFF), the network device, when configuring the CC, deems it necessary to occupy a continuous CC receiving channel corresponding to one band parameter of the first frequency band (e.g., the band parameter corresponding to the feature set carrying the first information) to receive the wake-up signal. For example, the protocol can define, note: Replace one continuous CC group by the LP-WUR receiver in the band; (LP-WUS and MR can be received simultaneously with any other CC in this band). For instance, the network device can configure N+1 groups of continuous CCs based on N+1 band parameters, configure the wake-up signal on the continuous CC corresponding to one of the band parameters (e.g., the band parameter corresponding to the feature set carrying the first information), and configure the master receiver to receive on the continuous CCs corresponding to the remaining N band parameters.

[0122] If the first information indicates that simultaneous reception of the wake-up signal and the main receiver is supported, or if the first information indicates that simultaneous reception of the wake-up signal and the main receiver is enabled (e.g., the first information is ON), the network device, when configuring CC, assumes that it does not need to occupy a continuous CC reception channel corresponding to one frequency band parameter of the first frequency band for receiving the wake-up signal. For example, the network device can configure N+1 groups of continuous CCs according to N+1 frequency band parameters, configure the wake-up signal on one of the continuous CCs corresponding to one of the frequency band parameters, and configure the main receiver to receive on the continuous CCs corresponding to the N+1 frequency band parameters.

[0123] Optionally, the network device can also configure continuous CCs corresponding to other frequency bands included in the first frequency band combination. For example, it can configure continuous CCs corresponding to other frequency bands according to the frequency band parameters of other frequency bands, and configure the main receiver to receive on the continuous CCs.

[0124] The following uses the NR band (78) as an example to introduce the first capability information, assuming that the first band supports 3 consecutive CCs. The first capability information includes the capability information of the first band combination, such as... Figure 10 As shown, the capability information of the first frequency band combination includes three frequency band parameters (i.e., frequency band parameter 1 to frequency band parameter 3) and a feature set corresponding to frequency band parameter 1 of the first frequency band. Optionally, it may also include a feature set of frequency band parameter 2 and the corresponding feature set of frequency band parameter 3. Each frequency band parameter is used to configure a set of consecutive CCs. The feature set corresponding to frequency band parameter 1 of the first frequency band carries a co-reception indication (i.e., first information). The co-reception indication is used to indicate whether the first frequency band supports simultaneous reception of the wake-up signal and the main receiver (or to indicate whether simultaneous reception of the wake-up signal and the main receiver is enabled on the first frequency band). Optionally, the feature set of the first frequency band may also indicate support for the wake-up signal.

[0125] Method 3 The first information is carried in a frequency band parameter of the first frequency band. That is, the first capability information includes the capability information of the first frequency band combination, the capability information of the first frequency band combination includes the first frequency band parameter of the first frequency band, and the first frequency band parameter includes the first information.

[0126] In one possible implementation, the first information can implicitly indicate support for simultaneous reception of the wake-up signal and the main receiver. For example, if the frequency band parameters of a frequency band include indication information supporting simultaneous reception of the wake-up signal and the main receiver, it means that the terminal device can simultaneously receive the wake-up signal and the main receiver within that frequency band. If the frequency band parameters of a frequency band do not include indication information supporting simultaneous reception of the wake-up signal and the main receiver, it means that the terminal device cannot simultaneously receive the wake-up signal and the main receiver within that frequency band.

[0127] In another possible implementation, the first information can explicitly indicate support for simultaneous reception of the wake-up signal and the main receiver. For example, if the first information takes a first value, this indicates that the terminal device can simultaneously receive the wake-up signal and the main receiver within the first frequency band. If the first information takes a second value, it indicates that the terminal device cannot simultaneously receive the wake-up signal and the main receiver within the first frequency band.

[0128] The first capability information is introduced below using the first frequency band as the NR frequency band (78) as an example. It is assumed that the first frequency band supports 3 consecutive CCs.

[0129] like Figure 11 As shown, the capability information of the first frequency band combination includes three frequency band parameters of the first frequency band, wherein each frequency band parameter is used to configure a set of consecutive CCs, and one of the three frequency band parameters (i.e. the first frequency band parameter) includes first information.

[0130] Optionally, in the above three methods, only one frequency band in the first frequency band combination is configured with a wake-up signal.

[0131] In this application, the terminal device's ability to receive the wake-up signal and the main receiver simultaneously when reporting the frequency band combination configuration helps avoid conflicts between the wake-up signal and the main receiver. For example, on the one hand, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the receiving performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0132] Example 2:

[0133] Another communication method provided in this application embodiment addresses the issue of conflict between the wake-up signal and the main receiver reception. In this method, the terminal device can avoid the first measurement occasion of the downlink signal when monitoring the wake-up signal.

[0134] In one implementation, if the first monitoring timing of the wake-up signal and the first measurement timing of the downlink signal overlap within M first time units, the network device does not send a wake-up signal within those M first time units, and the terminal device does not receive a wake-up signal within those M first time units. The downlink signal includes the SSB and / or the downlink reference signal.

[0135] Furthermore, the network device can send a wake-up signal M second time units after the first measurement opportunity. Correspondingly, the terminal device receives the wake-up signal M second time units after the first measurement opportunity.

[0136] For example, the first time unit and the second time unit mentioned above can be symbols or time slots.

[0137] In another implementation, if the second monitoring timing of the wake-up signal overlaps with the second measurement timing of the downlink signal, the network device does not send a wake-up signal during the second monitoring timing. Correspondingly, the terminal device does not receive a wake-up signal during the second monitoring timing.

[0138] Furthermore, if the number of monitoring opportunities that do not overlap with the downlink signal measurement opportunities is greater than or equal to a threshold, the terminal device can determine whether to wake up based on the wake-up signal on the monitoring opportunities that do not overlap with the downlink signal measurement opportunities.

[0139] If the number of monitoring opportunities that do not overlap with the downlink signal measurement opportunity is less than or equal to a threshold, the terminal device can determine whether to wake up, or this can be described as a default wake-up. This can be understood as the terminal device no longer determining whether to wake up based on wake-up signals on monitoring opportunities that do not overlap with the downlink signal measurement opportunity, but instead wakes up directly.

[0140] The following section introduces two avoidance methods from different time domain dimensions.

[0141] Method 1: Symbolic dimension.

[0142] In one approach, if a symbol in the monitoring timing of the wake-up signal overlaps in the time domain with a symbol in the measurement timing of the downlink signal, the wake-up signal can be postponed on that symbol.

[0143] In this context, delaying the signal on that symbol can be understood as not sending the wake-up signal on that symbol, but sending it on a symbol after the measurement time. This delayed transmission method helps to ensure sufficient time-domain resources for the wake-up signal, improves the wake-up accuracy of the terminal device, avoids increased power consumption due to false wake-ups, and avoids communication problems caused by delayed wake-ups. The understanding of delaying the signal on time slots is similar in the following text and will not be repeated.

[0144] In another approach, if a symbol in the monitoring timing of the wake-up signal overlaps in the time domain with a symbol in the measurement timing of the downlink signal, the wake-up signal can be dropped on that symbol.

[0145] In this context, "discarding on a symbol" can be understood as not sending a wake-up signal on that symbol. The understanding of "discarding on a time slot" is similar below and will not be repeated.

[0146] Method 2: Time slot dimension.

[0147] In one approach, if a time slot in the monitoring timing of the wake-up signal overlaps in the time domain with a time slot in the measurement timing of the downlink signal, the wake-up signal can be delayed on that symbol.

[0148] In another approach, if a time slot in the monitoring of the wake-up signal overlaps in the time domain with a time slot in the measurement of the downlink signal, the wake-up signal can be discarded in that time slot.

[0149] Method 3: Monitoring timing dimension.

[0150] In one approach, if a monitoring opportunity of the wake-up signal overlaps with the measurement opportunity of the downlink signal in the time domain, then the monitoring opportunity can be considered invalid.

[0151] Furthermore, if the number of valid monitoring opportunities is greater than or equal to X, the terminal device can continue to monitor valid monitoring opportunities and determine whether to wake up based on the valid monitoring opportunities.

[0152] If the number of valid monitoring opportunities is less than or equal to X, the terminal device can be woken up by default.

[0153] Where X is a value greater than 0.

[0154] This application addresses the conflict between the wake-up signal and the main receiver by having the terminal device avoid the first measurement opportunity of the downlink signal when monitoring the wake-up signal. This helps to avoid the conflict between the wake-up signal and the main receiver. For example, it can improve the wake-up accuracy of the terminal device, thereby avoiding increased power consumption caused by false wake-ups and communication problems caused by delayed wake-ups. On the other hand, it can improve the reception performance of the main receiver, such as the accuracy of RRM measurement and CSI-RS measurement.

[0155] It should be noted that the above two embodiments can be implemented individually or combined as a single solution.

[0156] Based on the same inventive concept as the method embodiments, this application provides a communication device, the structure of which can be as follows: Figure 12 As shown, it includes a communication unit 601 and a processing unit 602.

[0164] Optionally, the processing unit 602 is further configured to: if the number of monitoring opportunities in the wake-up signal monitoring opportunities that do not overlap with the downlink signal measurement opportunity is greater than or equal to a threshold, then determine whether to wake up based on the wake-up signal on the monitoring opportunity that does not overlap with the downlink signal measurement opportunity. And, if the number of monitoring opportunities in the wake-up signal monitoring opportunities that do not overlap with the downlink signal measurement opportunity is less than or equal to the threshold, then determine to wake up.

[0166] In one possible approach, the communication device can be as follows: Figure 13 As shown, the device can be a communication device or a chip within a communication device, wherein the communication device can be the terminal device in the above embodiments or the network device in the above embodiments.
