[0055] As described in the background, the future sixth-generation mobile communication technology (6G) may introduce a sensing function, and the allocation mechanism of resources for sensing and resources for communication is not clear at the present stage.

[0056] If the resource allocation is unreasonable, at least one of the sensing service and the communication service cannot be processed in time and correctly, affecting the user experience. Specifically, the multiplexing methods commonly used in New Radio (NR) mainly include Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), and Code Division Multiplexing (CDM). If communication and sensing are multiplexed in the CDM mode, the UE can only perform one type of service at the same time, which is obviously not conducive to performing delay-sensitive services. For example, if the communication service is sensitive to delay, and the UE is configured to perform the sensing service in the next period of time, it is very likely that the communication service will timeout by the time the sensing service is completed, causing the user to be unable to correctly enjoy the services provided by the communication service. If communication and sensing use CDM, the implementation cost at the UE side is high, and the overall scheme implementation complexity is also large.

[0057] Therefore, it is a better solution to use FDM for communication and sensing, but there is still a lack of suitable processing mechanism to realize FDM of communication and sensing at present.

[0058] To solve the above technical problems, the embodiment of the present disclosure provides a communication method, comprising: a network device sends configuration information to a UE, correspondingly, the UE receives the configuration information, the configuration information is used to configure a first frequency domain resource and a second frequency domain resource, the first frequency domain resource is used for sensing, and the second frequency domain resource is used for communication; the UE uses the first frequency domain resource to send a sensing signal, correspondingly, the network device receives a back signal, the back signal is associated with the sensing signal sent via the first frequency domain resource; and the UE uses the second frequency domain resource to communicate with the network device.

[0059] Therefore, the present disclosure can realize frequency division multiplexing of communication and sensing, so that the UE can perform communication service and sensing service in parallel, and improve the service processing efficiency. Specifically, the first frequency domain resource and the second frequency domain resource of the frequency division multiplexing are allocated to the UE through the configuration information, and the first frequency domain resource and the second frequency domain resource can correspond to the same time unit, so that the UE can perform the communication service and the sensing service in the same time unit. Therefore, the sensing service and the communication service can be realized in time, which is particularly advantageous for time-sensitive services.

[0060] The sensing service in the embodiment of the present disclosure refers to a service in which a sensing node (also referred to as a sensing device) with a sensing function performs sensing on a sensing target to obtain sensing target related information. The sensing service can be applied to the field of Internet of Things. In some embodiments, the sensing service can include a speed sensing service for estimating the moving speed of the sensing target. In other embodiments, the sensing service can include a distance sensing service for estimating the distance of the sensing target. The sensing service belongs to the services provided by the sensing scenario of the communication and sensing integrated (referred to as C&S integrated) system. In the sensing scenario, the sensing node as the sensing initiator sends the sensing signal, the sensing node as the sensing responder receives the signal generated after the sensing signal acts on the sensing target, and performs sensing algorithm processing on the received signal. For the processed sensing result, it can be reported to the base station or the sensing function (SF) through the uplink channel, or it can be used by the sensing node that receives the signal, or it can be used by other UEs. The sensing function can be a network element of the core network. The sensing node can be a UE or a network device.

[0061] For the single-station sensing mode, the sensing initiator and the sensing receiver are the same sensing node, that is, the sensing node itself transmits the sensing signal and receives the signal returned after the sensing signal acts on the sensing target. The signal received by the sensing receiver in the single-station sensing mode is referred to as the echo signal. The sensing types using the single-station sensing mode can include UE self-transmission and self-reception and network device self-transmission and self-reception.

[0062] For the double-station sensing mode, the sensing initiator and the sensing receiver can be different sensing nodes, that is, sensing node A transmits the sensing signal, and sensing node B receives the signal generated after the sensing signal acts on the sensing target. The signal received by the sensing receiver in the double-station sensing mode is usually referred to as the received signal. In this embodiment, for the convenience of description, the signals received by the sensing receivers in the single-station and double-station sensing modes are collectively referred to as echo signals. The sensing types using the double-station sensing mode can include network device transmission and UE reception, network device a transmission and network device b reception, UE transmission and network device reception, and UE a transmission and UE b reception. For the convenience of description, the sensing initiator is referred to as the a end, and the sensing receiver is referred to as the b end in this embodiment. In some embodiments, for the sensing mode of a transmission and b reception, the a end can also receive the sensing echo signal, that is, the sensing initiator can perform the single-station sensing mode while performing the double-station sensing mode at this time.

[0063] In order to make the above-mentioned purposes, features and beneficial effects of the present disclosure more obvious and easy to understand, the specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0064] FIG. 1 is a flowchart of a communication method according to a first embodiment of the present disclosure.

[0065] The present embodiment can be applied to the application scenario in which both communication services and sensing services exist between the UE and the network device.

[0066] In specific embodiments, the communication method provided by the steps S101-S103 below can be executed by a chip with a communication function in the UE or a baseband chip in the UE. In this specific embodiment, the UE can act as a sensing initiator in a sensing scenario.

[0067] Specifically, with reference to FIG. 1, the communication method of the present embodiment can include the following steps:

[0068] Step S101, receiving configuration information, the configuration information being used to configure a first frequency domain resource and a second frequency domain resource, the first frequency domain resource being used for sensing, and the second frequency domain resource being used for communication;

[0069] Step S102, transmitting a sensing signal using the first frequency domain resource;

[0070] Step S103, performing communication using the second frequency domain resource.

[0071] Step S102 and step S103 can be executed in parallel. The two steps can be executed simultaneously, or sequentially (for example, the embodiments shown in FIG. 7 and FIG. 8 switch between the first frequency domain resource and the second frequency domain resource to perform communication and sensing in turn).

[0072] More specifically, referring to FIG. 2, the total resources available for network device configuration are divided into the second frequency domain resource for communication and the first frequency domain resource for sensing in the frequency domain. That is, the signal or signal for sensing is frequency division multiplexed with the signal or channel for communication.

[0073] The second frequency domain resource may, for example, include a frequency domain resource for transmitting data, a frequency domain resource for transmitting a physical uplink control channel (PUCCH), a frequency domain resource for transmitting a physical downlink shared channel (PDSCH), and the like.

[0074] The type of information that can be transmitted on the first frequency domain resource can include a sensing reference signal for sensing, or sensing result information measured based on the sensing reference signal, and can also include high-level signaling for establishing a link between the UE and the network device, and the like.

[0075] In the application scenario, the resources for communication and the resources for sensing are frequency division multiplexed, for example, the total resources occupy a number of subcarriers in the frequency domain, n subcarriers (n>0) are allocated to the first frequency domain resource, and the remaining subcarriers can be all or partially allocated to the second frequency domain resource. Further, the first frequency domain resource and the second frequency domain resource can correspond to the same time domain resource. Thus, the communication service and the sensing service can be performed simultaneously.

[0076] In some embodiments, the sensing signal can include a sensing reference signal, i.e., a reference signal for sensing, such as a channel state information-reference signal (CSI-RS), a positioning reference signal (PRS), and a sounding reference signal (SRS).

[0077] Further, the frequency division multiplexing with the communication can also be, for example, an echo signal, which carries sensing information (i.e., sensing result) for the sensing target.

[0078] Further, the communication frequency division multiplexing can also be, for example, a measurement report, which is based on echo signal processing.

[0079] In some embodiments, the sensing signal can be carried in the form of a channel. In this example, the sensing signal can be referred to as a sensing channel, i.e., a channel for sensing.

[0080] The information mentioned in the present application can be configured by the network side through high layer signaling (such as Radio Resource Control (RRC)) or can be carried by Downlink Control Information (DCI) or Medium Access Control-Control Element (MAC-CE).

[0081] In general, the frequency domain multiplexing manner of sensing and communication can be divided into three levels according to the carrier component (CC) level, the bandwidth part (BWP) level, and the inner-BWP level. Next, the specific implementation of the three levels will be described in detail.

[0082] In one specific embodiment, for the frequency division multiplexing of communication and sensing in the CC-level case, any of the first frequency domain resource and the second frequency domain resource can include a carrier.

[0083] Specifically, the configuration information can include first information for configuring at least one carrier. For example, the configuration information can include at least one of the following information: the index of each carrier, the frequency band of each carrier in the frequency domain, and the corresponding preset maximum transmit power of each carrier. The preset maximum transmit power refers to the maximum allowed transmit power of the UE configured on the serving cell c and the carrier f.

[0084] Further, the configuration information can also include indication information for indicating the association relationship between at least one carrier and sensing.

[0085] For example, it can be indicated by 1 bit to enable or disable whether the corresponding carrier has the sensing function. Assuming that the indication information of carrier 1 (CC-1) is assigned a value of 0, it indicates that the carrier 1 does not have the sensing function, i.e., the carrier 1 belongs to the second frequency domain resource for communication. Assuming that the indication information of carrier 2 (CC-2) is assigned a value of 1, it indicates that the carrier 2 has the sensing function, i.e., the carrier 2 belongs to the first frequency domain resource for sensing.

[0086] Thus, the first frequency domain resource and the second frequency domain resource can be selected from the same carrier group, and the network side does not need to pre-configure corresponding carrier groups for different types of services, which is beneficial to improve the resource utilization.

[0087] In one specific embodiment, the concept of carrier group for sensing can be introduced, that is, a carrier group for sensing (denoted as a first carrier group) and / or a carrier group for communication (denoted as a second carrier group) are pre-configured and divided. There can be multiple first carrier groups, and there can also be multiple second carrier groups. For any carrier group in the first carrier group and the second carrier group, at least one carrier can be included in a single carrier group.

[0088] Correspondingly, the at least one carrier group configured in the configuration information can be selected from the at least one first carrier group and the at least one second carrier group.

[0089] For example, referring to FIG. 3, the first carrier group can include carrier 1 (CC-1), carrier 2 (CC-2), and carrier 3 (CC-3), and the transmission direction of each carrier in the time domain is as shown in the figure, D-S represents a downlink transmission slot for sensing, X represents a flexible slot or a flexible symbol, and U-S represents an uplink transmission slot for sensing.

[0090] Continuing to refer to FIG. 3, the second carrier group can include carrier 4 (CC-4), carrier 5 (CC-5), and carrier 6 (CC-6), and the transmission direction of each carrier in the time domain is as shown in the figure, D represents downlink, X represents flexible, and U represents uplink.

[0091] Further, the configuration information can select at least one carrier or one carrier group from the first carrier group and the second carrier group and configure the UE. For example, assuming that the configuration information includes indexes 1 and 5, it indicates that the UE is configured with CC-1 for sensing and CC-5 for communication, and correspondingly, CC-1 is the first frequency domain resource and CC-5 is the second frequency domain resource. For another example, the configuration information includes indexes 1, 3, and 5, which indicates that the UE is configured with CC-1 and CC-3 for sensing and CC-5 for communication, and correspondingly, CC-1 and CC-3 are the first frequency domain resources and CC-5 is the second frequency domain resource.

[0092] In some embodiments, each carrier can have a corresponding preset maximum transmission power. For example, CC-1, CC-2, and CC-3 correspond to preset maximum transmission powers for sensing Ps-cmax,f,c respectively, and CC-4, CC-5, and CC-6 correspond to preset maximum transmission powers Pcmax,f,c respectively. The specific values of the three Ps-cmax,f,c can be the same or different, and similarly, the specific values of the three Pcmax,f,c can be the same or different.

[0093] The network side can configure, through high-layer signaling, an upper bound value and a lower bound value of the preset maximum transmission power corresponding to each carrier used for sensing. That is, the preset maximum transmission power of the UE when transmitting the sensing signal using the configured carrier can take any value in the preset value interval = [upper bound value, lower bound value] configured by the high-layer signaling. Similarly, the network device can also configure, through high-layer signaling, an upper bound value and a lower bound value of the preset maximum transmission power corresponding to each carrier used for communication.

[0094] Further, for each carrier in the at least one carrier configured by the configuration information, the transmission power for transmitting the sensing signal or performing communication using the carrier is not greater than the preset maximum transmission power corresponding to the carrier. For example, the transmission power of the UE for transmitting the sensing signal using CC-1 cannot be greater than Ps-cmax,f,c corresponding to CC-1. For another example, the transmission power of the UE for performing communication using CC-4 needs to be less than or equal to Pcmax,f,c corresponding to CC-4.

[0095] Further, the sum of the transmission power for transmitting the sensing signal using the first frequency domain resource and the transmission power for performing communication using the second frequency domain resource is not greater than the preset total maximum transmission power (denoted as Pcmax). Still taking the configuration information including indexes 1, 3 and 5 for example, the sum of the transmission power of the UE for transmitting the sensing signal using CC-1, the transmission power of the UE for transmitting the sensing signal using CC-3 and the transmission power of the UE for performing communication using CC-5 cannot be greater than Pcmax.

[0096] Further, Pcmax can also be configured to the UE through the configuration information.

[0097] Therefore, the carrier group used for sensing and the carrier group used for communication each have a corresponding maximum transmission power (i.e., the preset maximum transmission power), and then together have the same greater power constraint (i.e., the preset total maximum transmission power). This is conducive to reasonably determining the power allocation between the two types of services when the communication and sensing are frequency division multiplexed.

[0098] In some embodiments, in the case of power limitation, that is, the sum of the transmission power for transmitting the sensing signal using the first frequency domain resource and the transmission power for performing communication using the second frequency domain resource exceeds the preset total maximum transmission power, the sensing priority (or communication priority) mode can be adopted to preferentially allocate the transmission power to the sensing service (or the communication service).

[0099] Specifically, the protocol can specify whether the power allocation is performed in the sensing priority mode or the communication priority mode when the power is limited. At this time, the transmission power on the frequency domain resource corresponding to the communication or sensing service with a lower priority is limited.

[0100] In some embodiments, carriers in the first carrier group and carriers in the second carrier group can exist in cross, that is, one carrier can be used for both communication and sensing. The configuration information can indicate (for example, by the aforementioned 1-bit indication information) the service that the carrier serves this time. In the present example, the same carrier can be configured with two preset maximum transmit powers.

[0101] Specifically, the preset maximum transmit power corresponding to the carrier can include a first power and a second power, the first power being associated with sensing, and the second power being associated with communication. In other words, the same carrier can be configured with both Ps-cmax,f,c and Pcmax,f,c.

[0102] Further, the preset maximum transmit power corresponding to the carrier is determined according to the type of signal / channel / data that the carrier specifically transmits at the current time.

[0103] For example, referring to FIG. 4, the network device can pre-configure (for example, through high-layer signaling) three carrier groups: a first carrier group 1, a first carrier group 2, and a second carrier group, wherein the first carrier group 1 includes CC-1, CC-2, and CC-3, the first carrier group 2 includes CC-4 and CC-7, and the second carrier group includes CC-4, CC-5, and CC-6. It can be seen that the first carrier group 2 and the second carrier group share CC-4.

[0104] Further, CC-4 can be configured with a first power Ps-cmax,f,c and a second power Pcmax,f,c. Assuming that the configuration information indicates that the first frequency domain resource includes CC-4 and CC-1, and the second frequency domain resource includes CC-5 and CC-6, the UE determines to use the first power Ps-cmax,f,c corresponding to CC-4 as the power allocation constraint condition when using CC-4 to transmit a sensing signal.

[0105] In some embodiments, the configuration information can indicate that the first frequency domain resource and the second frequency domain resource both include CC-4, and the UE can determine to use the first power Ps-cmax,f,c and the second power Pcmax,f,c as the power allocation constraint condition according to the type of service that the UE actually uses CC-4 to perform at the current time. For example, assuming that according to the scheduling of the network device, the UE uses CC-4 to transmit a sensing signal at time t1, the UE determines to use the first power Ps-cmax,f,c corresponding to CC-4 as the power allocation constraint condition at time t1. For another example, assuming that with further scheduling of the network device, the UE uses CC-4 to receive downlink data from the network device at time t2, the UE determines to use the second power Pcmax,f,c corresponding to CC-4 as the power allocation constraint condition at time t2.

[0106] In some embodiments, the first set of carriers and the second set of carriers can have no intersection, i.e., each carrier is fixedly serving a single service, as shown in FIG. 3.

[0107] In some embodiments, the value of Ps-cmax,f,c can be equal to the value of Pcmax,f,c. In this case, the network side can not need to additionally configure the specific value of Ps-cmax,f,c.

[0108] In some embodiments, the upper bound of Ps-cmax,f,c can be equal to the upper bound of Pcmax,f,c, and / or the lower bound of Ps-cmax,f,c can be equal to the lower bound of Pcmax,f,c.

[0109] In one specific implementation, for frequency division multiplexing of communication and sensing in the BWP-level case, the first frequency domain resource can include a first BWP, and the second frequency domain resource can include a second BWP. The second BWP is a BWP independent of the first BWP, in other words, an independent BWP can be configured for sensing.

[0110] Specifically, the configuration information can include second information, at least for configuring the second BWP.

[0111] In some embodiments, 1 activated BWP can be configured for sensing within one carrier. Optionally, there can be 2 activated BWPs in one carrier at the same time, one for sensing and the other for communication. Among them, the 2 activated BWPs can be an initial BWP for sensing and an initial BWP for communication, or can also be a non-initial BWP for sensing and a non-initial BWP for communication.

[0112] In some embodiments, the related parameter information of the initial second BWP can be added in the configuration information. The specific parameter type and content can refer to the configuration provisions of the BWP in the existing communication protocol.

[0113] For example, the initial downlink BWP for sensing (initialDownlinkBWPforsensing) parameter can be added in the downlink common configuration information element (DownlinkConfigCommon information element) to configure the related information of the initial second BWP. The initial second BWP refers to the default activated second BWP, i.e., the initial activated BWP for sensing.

[0114] For example, a downlink BWP for sensing-to-release list (downlinkBWPforsensing-ToReleaseList) and a downlink BWP for sensing-to-add-modify list (downlinkBWPforsensing-ToAddModList) can be added in the ServingCellConfig information element to configure the information of the candidate second BWP that can be switched by the UE. Optionally, the UE can switch from the currently activated second BWP to the candidate second BWP according to the switching instruction sent by the network device, and the candidate second BWP becomes the activated BWP accordingly.

[0115] Further, the second information can also be used to configure the first BWP. For example, the initial first BWP can be configured by the initial downlink BWP (initialDownlinkBWP) parameter in the DownlinkConfigCommon information element. The initial first BWP refers to the default activated first BWP, i.e., the initial activated BWP for communication.

[0116] For example, one or more candidate second BWPs can be configured by the downlink BWP-to-release list (downlinkBWP-ToReleaseList) and the downlink BWP-to-add-modify list (downlinkBWP-ToAddModList) in the ServingCellConfig information element.

[0117] In some embodiments, the configuration information can further include third information for activating the first BWP and / or the second BWP. The third information can be, for example, the aforementioned switching instruction for switching the activated first BWP among the plurality of candidate first BWPs, and similarly, the third information can be used to switch the activated second BWP among the plurality of candidate second BWPs.

[0118] For example, the third information can be carried in RRC or DCI or MAC-CE.

[0119] In some embodiments, the activation state of the first BWP and / or the second BWP can also be switched in response to the expiration of a timer.

[0120] In one specific implementation, the first BWP and the second BWP can belong to the same carrier, and both the first BWP and the second BWP are activated BWPs. In other words, the UE can have two activated BWPs on one CC at the same time.

[0121] For example, assuming that 4 BWPs are configured in a carrier, the prior art can only have one active BWP at the same time, while the present embodiment can configure 2 BWPs for communication and 2 BWPs for sensing in a CC, and have two active BWPs at the same time. One of the active BWPs is used for communication, and the other active BWP is used for sensing.

[0122] Further, the first BWP and the second BWP adopt the same duplex mode. That is, the duplex mode of the first BWP and the second BWP is determined according to the configuration result of the band level to which both of them belong.

[0123] In some embodiments, the band level can be configured (for example, resource configuration) in a time division duplexing (TDD) mode, and all BWPs of all carriers in the band are TDD. Optionally, the TDD time slot structure of the first BWP and the second BWP in a carrier can be completely consistent.

[0124] Referring to FIG. 5, CC-1 includes BWP-1 and BWP-2, wherein BWP-1 is the first BWP and BWP-2 is the second BWP. Further, BWP-1 and BWP-2 both adopt TDD for sensing or communication. Further, BWP-1 and BWP-2 are both active BWPs. In FIG. 5, BWP-1 and BWP-2 are both TDD, wherein the transmission direction from time t0 to time t1 is downlink, the transmission direction from time t1 to time t2 is flexible, and the transmission direction from time t2 to time t3 is uplink. The time length from time t0 to time t1 can include two time slots or two symbols. Accordingly, the UE can receive a backscatter signal via BWP-1 and perform downlink reception via BWP-2 from time t0 to time t1. The UE transmits a sensing signal via BWP-1 and performs uplink transmission via BWP-2 from time t2 to time t3.

[0125] Further, in the TDD mode, the transmission direction of the first BWP and the second BWP can be the same, as shown in FIG. 5. At this time, the transmission direction of the sensing signal is consistent with the communication direction. For example, the time slot format configuration of the first BWP and the second BWP can be indicated simultaneously by a tdd-UL / DL-ConfigurationCommon signaling.

[0126] Alternatively, in a TDD mode, the transmission directions of the first BWP and the second BWP can be different. For example, during the time period from time t0 to time t1 in FIG. 5, the transmission direction of BWP-1 is uplink, and the transmission direction of BWP-2 is downlink. In some embodiments, the time slot structures of the first BWP and the second BWP can be respectively configured by two tdd-UL / DL-ConfigurationCommon signals. For example, tdd-UL / DL-ConfigurationCommon is used to configure the time slot structure of the second BWP, and tdd-UL / DL-ConfigurationCommon2 is used to configure the time slot structure of the first BWP.

[0127] In some other embodiments, the frequency band level configuration is configured in a Frequency Division Duplexing (FDD) mode, and all BWPs of all carriers in the frequency band are FDD.

[0128] Specifically, referring to FIG. 6, the FDD configuration of the frequency band level includes a pure uplink frequency band, for example, BWP-1 and BWP-2 in CC-1, the former being the first BWP and the latter being the second BWP. Further, the FDD configuration of the frequency band level also includes a pure downlink frequency band, for example, BWP-1 and BWP-2 in CC-2, the former being the first BWP and the latter being the second BWP.

[0129] Further, the configuration information in step S101 can be obtained by selecting a BWP combination in CC-1 and CC-2. For example, the configuration information can indicate BWP-1 of CC-1 and BWP-2 of CC-2, and accordingly, the UE can receive the sensing signal via BWP-1 of CC-1 or the network device can receive the echo signal via BWP-1 of CC-1 and perform uplink communication via BWP-2 of CC-2. For another example, the configuration information can indicate BWP-1 and BWP-2 of CC-1, and accordingly, the network device receives the echo signal via BWP-1 of CC-1 and performs downlink communication via BWP-2 of CC-1.

[0130] In this way, the efficiency of service processing can be maximized, that is, the UE can perform sensing service and communication service on two activated BWPs respectively at the same time.

[0131] In one embodiment, the first BWP and the second BWP belong to the same carrier, and the first BWP and the second BWP can be switched alternately as an active BWP. That is, although independent BWPs dedicated to sensing are configured in the carrier, the UE still has at most one active BWP at the same time on one CC, and the sensing service is implemented in the form of switching. Thus, the UE prepares a set of BWP radio frequency resources to realize sensing and communication services in frequency division multiplexing, which is low in cost.

[0132] For sensing services triggered by dynamic scheduling, after step S101 and before step S102, the communication method of the embodiment can further include the step of receiving sensing trigger information, which can be used to trigger the sending of sensing signals or to indicate switching to the first BWP.

[0133] For example, the UE can default to communicating on the second BWP, and in response to receiving the sensing trigger information, the UE can default to switching to the first BWP for sensing.

[0134] In some embodiments, the sensing trigger information can be carried in DCI or MAC-CE or RRC signaling.

[0135] In some embodiments, the configuration information can be used to configure a plurality of candidate BWPs, all of which are used for sensing. Different candidate BWPs can be used for different sensing, such as different specific classification of sensing services, different needs, etc. The corresponding candidate BWP can be configured respectively.

[0136] Further, the sensing trigger information can also be used to indicate a target BWP as the first BWP, and the target BWP is selected from the plurality of candidate BWPs.

[0137] Further, the sensing trigger information can carry the index (BWP-ID) of the BWP, and the UE determines the candidate BWP corresponding to the index as the first BWP. For example, referring to FIG. 7, assuming that the configuration information configures 4 BWPs, BWP-2 is the second BWP, BWP-1, BWP-3 and BWP-4 are all used for sensing (i.e. these three BWPs are all candidate BWPs), and the BWP-ID carried by the DCI is 1, then the UE determines that it needs to switch to BWP-1 to send the sensing signal. At this time, BWP-1 is the first BWP.

[0138] Further, continuing to refer to FIG. 7, in response to the completion of the sensing service on BWP-1, the UE can actively switch back to BWP-2 to continue the communication service. In FIG. 7, the dashed line indicates that the resource at this place is not actually used.

[0139] For periodic or ongoing sensing service, the UE can periodically switch between the first BWP and the second BWP to periodically or ongoingly transmit sensing signals, as shown in FIG. 8.

[0140] Specifically, since the UE knows in advance that it needs to switch to another service-associated BWP, the UE can start accurate switching a period of time before the actual transmission of signals / channels / data of the service, which can also be referred to as preparation time. During the preparation time, the UE can prepare the signals / channels / data to be transmitted on the BWP to be switched to, so as to start the transmission of the signals / channels / data immediately after switching. In some embodiments, the specific value of the preparation time can refer to the value specified in the existing BWP switching related protocol. In actual application, the foregoing value can also be adjusted as needed to reasonably determine the use time of the preparation time.

[0141] For example, referring to FIG. 8, the configuration information configures BWP-1 as the first BWP and BWP-2 as the second BWP, and configures the UE to periodically transmit sensing signals. Then the UE can periodically switch between BWP-2 and BWP-1 to perform communication service and sensing service, respectively.

[0142] In a typical application scenario, continuing to refer to FIG. 8, assuming that the UE uses the self-initiated and self-received mode for sensing, the UE has previously switched to BWP-1 to transmit sensing signals and switched back to BWP-2 to perform downlink reception. Then the UE switches from BWP-2 to BWP-1 at the next sensing period, and receives echo signals via BWP-1. In response to receiving the echo signals, the UE periodically switches back to BWP-2 to perform uplink transmission. During the uplink transmission, the UE can process the received echo signals in the background to obtain sensing results, and then generate a measurement report based on the sensing results. Further, the UE can switch from BWP-2 to BWP-1 at the next sensing period, and report the measurement report to the network device via BWP-1.

[0143] In one specific embodiment, in response to the time period of using the second BWP for communication and the time period of using the first BWP for transmitting sensing signals being overlapping, the UE can determine whether to switch the active BWP according to the priority ranking of communication and sensing.

[0144] Specifically, although the UE can concurrently transmit and receive, concurrently receive, and concurrently transmit and receive on the two BWP when there is an overlapping time period, considering that there will still be some interference, it is preferred to ensure that the service on one of the BWP is smoothly performed.

[0145] Further, the time period for transmitting the sensing signal using the first BWP can include an actual transmission duration and / or a retuning time for head-tail BWP switching.

[0146] In response to a priority of a signal or channel transmitted on the post-switch BWP being higher than a priority of a signal or channel transmitted on the pre-switch BWP that overlaps with the post-switch BWP, determining to switch the active BWP.

[0147] In response to a priority of a signal or channel transmitted on the post-switch BWP being lower than a priority of a signal or channel transmitted on the pre-switch BWP that overlaps with the post-switch BWP, determining not to switch the active BWP.

[0148] In some embodiments, a priority of control signaling, synchronization signaling can be predefined to be higher than a priority of the sensing signal. The control signaling may, for example, be a Physical Random Access Channel (PRACH), a Physical Downlink Control Channel (PDCCH), a Physical Uplink Control Channel (PUCCH). The synchronization signaling may, for example, be a Synchronization Signal / Physical Broadcast Channel Block (SS / PBCH BLOCK, i.e., SSB).

[0149] Assuming that the UE is currently receiving SSB on BWP-2, with reference to FIG. 8, if the reception of the SSB ends at time t0, the time period for communicating and the time period for transmitting the sensing signal do not overlap, and thus no priority comparison is needed. The UE can start preparing for switching at time t0 and switch to BWP-1 at time t1 to perform the sensing service.

[0150] If the end time of the SSB is after time t0, there will be an overlapping time period, and thus a priority comparison is needed. Since the priority of the SSB is higher than that of the sensing signal, the UE remains on BWP-2 without BWP switching. If the reception of the SSB ends before time t2 and the UE does not perform other communications, there is no overlapping time period at time t2, and thus the UE can start preparing for switching and switch to BWP-1 at time t3 to perform the sensing service.

[0151] In one specific implementation, for frequency division multiplexing of the communication and the sensing in the inner-BWP-level case, the first frequency domain resource can include a first sub-band, and the second frequency domain resource can include a second sub-band.

[0152] Specifically, the configuration information can comprise fourth information for configuring the first subband and the second subband. Further, the first subband and the second subband belong to the same BWP. For example, the fourth information can comprise at least one of the following parameters of the first subband and / or the second subband: subband start frequency domain position, subband end frequency domain position, subband bandwidth, etc.

[0153] In some embodiments, the transmission directions of the first subband and the second subband can be the same. For example, referring to FIG. 9, the BWP-1 comprises a subband-1 and a subband-2, both of which have a time slot format of DXU, where the subband-1 is configured as the first subband and the subband-2 is configured as the second subband.

[0154] The present example can be applicable to a non-subband full duplex (SBFD) scenario.

[0155] Further, the sum of the respective transmission powers of the UE on the first subband and the second subband at the same time does not exceed the preset maximum transmission power corresponding to the two subbands. The preset maximum transmission power is the preset maximum transmission power corresponding to the carrier to which the BWP to which the first subband and the second subband belong.

[0156] In response to the sum of the transmission power on the first subband and the transmission power on the second subband being greater than the corresponding preset maximum transmission power, the transmission power of one of the subbands can be limited according to the priority of the service. For example, if the priority of the communication service is higher, the transmission power of the first subband can be limited, i.e., the transmission power of the second subband is preferentially allocated. Or, if the priority of the sensing service is higher, the transmission power of the second subband can be limited, i.e., the transmission power of the first subband is preferentially allocated.

[0157] In some embodiments, the transmission directions of the first subband and the second subband in at least one time unit are different.

[0158] Specifically, the beam direction of the resource allocated for communication and the beam direction of the resource allocated for sensing can be different when actually configured, e.g., the beam direction for transmitting the sensing signal in the first subband is different from the beam direction for communication in the second subband.

[0159] At this time, it can be specified by a protocol that when the beam directions are inconsistent, the beam direction of one of the subbands is followed. For example, if it is specified that the communication beam is preferred, the first subband follows the beam direction of the second subband to transmit the sensing signal. For another example, if it is specified that the sensing beam is preferred, the second subband follows the beam direction of the first subband for communication.

[0160] In some embodiments, in the SBFD scenario, the first sub-band and the second sub-band are not in the same transmission direction in at least one time unit. At this time, transmission is performed on each sub-band in the respective configured transmission direction.

[0161] Specifically, some sub-bands can be independently configured for sensing. Correspondingly, the configuration information can include: fifth information, used to indicate that one or more sub-bands for SBFD are the first sub-band.

[0162] For example, one or more sub-bands configured for SBFD, or one or more SBFD sub-bands are additionally indicated by the fifth information for sensing.

[0163] Taking the view of label (a) in FIG. 10 as an example, BWP-1 is divided into two downlink sub-bands (sub-band-1 and sub-band-3) and one uplink sub-band (sub-band-2) without overlapping in the frequency domain, and the fifth information further indicates that sub-band-3 among them is the first sub-band.

[0164] Taking the view of label (b) in FIG. 10 as an example, BWP-2 is divided into two downlink sub-bands (sub-band-1 and sub-band-3) and one uplink sub-band (sub-band-2) without overlapping in the frequency domain, and the fifth information further indicates that sub-band-3 and sub-band-2 among them are the first sub-band.

[0165] In one specific embodiment, the subcarrier spacing (SCS) of the first frequency domain resource and the SCS of the second frequency domain resource can be independently configured. That is, the SCS of the first frequency domain resource and the SCS of the second frequency domain resource can be the same, as shown in the first carrier group 2 in FIG. 4 and the example shown in label (b) in FIG. 10. Alternatively, the SCS of the first frequency domain resource and the SCS of the second frequency domain resource can also be different, as shown in the first carrier group 1 in FIG. 3, FIG. 4, the example shown in FIG. 5, FIG. 7, FIG. 9, and label (a) in FIG. 10.

[0166] In one specific embodiment, the UE can also act as a sensing receiving end while acting as a sensing initiating end, receive the echo signal generated after the sensing signal (such as a sensing reference signal) transmitted via the first frequency domain resource acts on the sensing target, and process the echo signal to obtain a sensing result based on the echo signal. Based on the sensing result, a measurement report can be generated. Further, the UE can transmit the measurement report using the first frequency domain resource.

[0167] In one embodiment, before / after / simultaneously with step S101, the embodiment communication method can further comprise the step of: receiving sixth information indicating that a plurality of continuous time units in a preset period are used for sensing. The time unit can be the communication granularity of the UE and the network device in the time domain. For example, the time unit can be a time slot, a mini-slot (a time unit shorter than a time slot), a subframe, a symbol, a frame, etc. The same time unit refers to the same time unit. For example, the network side can specify a plurality of continuous time slots for sensing within a predefined period of time.

[0168] Specifically, the sensing purpose of the time slot can be that the network device transmits a sensing signal, or the UE transmits a sensing signal, or both.

[0169] Optionally, the plurality of continuous time slots can be a predefined position, such as a plurality of continuous time slots at the beginning of the preset period, or a plurality of continuous time slots at the end of the preset period, or a time slot position configured by the network side through high-layer signaling, such as a specific time slot position of the time slot for sensing configured through a bit map. Each bit in the bit map corresponds to 1 time slot in the preset period, and is configured as 0 to indicate that the time slot cannot be used for sensing, and is configured as 1 to indicate that the time slot can be used for sensing.

[0170] For example, in a period of 2 radio frames, there are a total of 20 time slots, and 4 of them can be specified for sensing. The specific positions of the 4 time slots can be determined in a predefined manner, such as the first 4 time slots of the 20 time slots, or the last 4 time slots of the 20 time slots, or other predefined positions. Alternatively, the specific positions of the 4 time slots can be configured by the network side through high-layer signaling. The above time slot structure appears periodically in the time domain.

[0171] In some embodiments, in response to receiving the configuration information and the sixth information, the UE and / or the network device can transmit a sensing signal using the first frequency domain resource on the plurality of continuous time units in the preset period indicated by the sixth information.

[0172] In one variant, the sixth information can be used to indicate that a plurality of uplink time units or a plurality of downlink time units in a preset period are used for sensing. For example, the network side can specify a plurality of uplink time slots or downlink time slots for sensing within a predefined period of time.

[0173] Specifically, the sensing use of the uplink time slots can be that the network device transmits the sensing signal or the UE transmits the sensing signal; and the sensing use of the downlink time slots can be that the network device transmits the sensing signal or the UE transmits the sensing signal.

[0174] Optionally, the plurality of uplink time slots can be a plurality of continuous uplink time slots or a plurality of discontinuous uplink time slots; and the plurality of downlink time slots can be a plurality of continuous downlink time slots or a plurality of discontinuous downlink time slots.

[0175] Optionally, the plurality of uplink time slots or the plurality of downlink time slots can be predefined positions, for example, a plurality of continuous uplink time slots or downlink time slots at the beginning of a preset period, or a plurality of continuous uplink time slots or downlink time slots at the end of a preset period, or time slot positions configured by the network side through high-layer signaling, for example, the specific time slot positions of the uplink time slots or the downlink time slots are configured through a bit map, each bit in the bit map corresponds to 1 time slot in the period, and a bit configured as 0 indicates that the time slot cannot be used for sensing, and a bit configured as 1 indicates that the time slot can be used for sensing.

[0176] For example, in a period of 2 radio frames, a total of 20 time slots are provided, and 4 time slots can be used for sensing. The specific positions of the 4 time slots can be determined in a predefined manner, for example, the first 4 uplink time slots of the 20 time slots, or the last 4 uplink time slots of the 20 time slots, or the first 4 downlink time slots of the 20 time slots, or the last 4 downlink time slots of the 20 time slots, or other predefined positions. Alternatively, the specific positions of the 4 time slots can be configured by the network side through high-layer signaling.

[0177] In some embodiments, in response to receiving the configuration information and the sixth information, the UE and / or the network device can transmit the sensing signal using the first frequency domain resource on the plurality of uplink time units or downlink time units in the preset period indicated by the sixth information.

[0178] As described above, by using the present embodiment, frequency division multiplexing of communication and sensing can be achieved, so that the UE can perform communication services and sensing services in parallel, thereby improving service processing efficiency. Specifically, the UE is allocated the first frequency domain resource and the second frequency domain resource for frequency division multiplexing by the configuration information, and the first frequency domain resource and the second frequency domain resource can correspond to the same time unit, so that the UE can perform communication services and sensing services in the same time unit. Therefore, the sensing services and the communication services can be timely implemented, which is particularly advantageous for time-sensitive services.

[0179] FIG. 11 is a flowchart of a communication method according to a second embodiment of the present disclosure.

[0180] In specific embodiments, the communication method provided by the steps S201-S203 can be executed by a chip with a communication function in the network device, or by a baseband chip in the network device. The network device can be, for example, a base station.

[0181] Specifically, referring to FIG. 11, the communication method of the present embodiment can include the following steps:

[0182] Step S201: sending configuration information, the configuration information being used to configure a first frequency domain resource and a second frequency domain resource, the first frequency domain resource being used for sensing, and the second frequency domain resource being used for communication;

[0183] Step S202: receiving a back echo signal, the back echo signal being associated with a sensing signal sent via the first frequency domain resource;

[0184] Step S203: using the second frequency domain resource for communication.

[0185] Those skilled in the art understand that the steps S201-S203 can be regarded as execution steps corresponding to the steps S101-S103 of the above-mentioned embodiments shown in FIGS. 1-10, and the two are complementary in specific implementation principles and logic. Therefore, the explanations of the terms involved in the present embodiment can refer to the related descriptions of the embodiments shown in FIGS. 1-10, which will not be repeated here.

[0186] Further, in the present specific embodiment, the UE is the sensing initiator, and the network device is the sensing receiver, so after the UE executes step S102 to send the sensing signal via the first frequency domain resource, the network device executes step S202 to receive the back echo signal generated after the sensing signal acts on the sensing target.

[0187] In the self-sensing and self-receiving scenario of the UE, step S202 can be replaced by: receiving a measurement report, the measurement report being obtained by the UE based on the received back echo signal.

[0188] In some embodiments, in response to the configuration information configuring a plurality of candidate BWPs, after step S201 and before step S202, the network device can further execute the step of: sending sensing trigger information, used to indicate a target BWP as the first BWP, the target BWP being selected from the plurality of candidate BWPs.

[0189] From the above, by using the present embodiment, frequency division multiplexing of communication and sensing can be achieved, and the communication efficiency can be improved.
