Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0002] In traditional communication systems, the transmitter sends data strictly according to the scheduling information. Meanwhile, the receiver receives data strictly according to the scheduling information. For each data transmission, the network only indicates one set of scheduling information, which is carried through Radio Resource Control (RRC) signaling and / or Downlink Control Information (DCI).

[0003] According to the current protocol, during the scheduling process, if an abnormal event occurs, the transmitter cancels data transmission and the receiver cancels data reception. For example, if the data is downlink data, but the time-frequency resources occupied by the data include uplink symbols, then this is considered an abnormal event. For another example, if the time-frequency resources occupied by the data are preempted by a higher-priority signal, then this is considered an abnormal event. In some special scenarios, although the transmitter and receiver cannot transmit and receive data according to the set of scheduling information indicated by the network side, they still have the ability to transmit and receive data.

[0041] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new radio (NR) systems, and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architecture, dual-connection architecture, vehicle-to-everything architecture and other architectures.

[0042] This application mainly relates to the communication between terminal devices and network devices. Among them:

[0043] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the devices that provide base station functions in the second-generation (2G) network include the base transceiver station (BTS), the devices that provide base station functions in the third-generation (3G) network include the node B (NodeB), and the devices that provide base station functions in the fourth-generation (4G) network include the evolved node B (eNB). In wireless local area networks (WLAN), the device that provides base station functions is the access point (AP), and the devices that provide base station functions in NR are the next generation node base station (gNB) and the evolved node B (ng-eNB). The gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0044] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0045] As described in the background art, in some special scenarios, although the sending end and the receiving end cannot send and receive data according to a set of scheduling information indicated by the network side, they still have the ability to send and receive data.

[0046] For example, in full-duplex scenarios, because the network needs to split the antenna array and use it for signal transmission and reception separately, full-duplex symbols may have a lower number of data transmission layers. Another example is in integrated communication and perception scenarios, because the perception signals cause interference, the perception symbols may have a lower modulation order.

[0047] In the technical solution of the present application, in full-duplex transmission scenarios and communication perception integration scenarios, when the terminal device and the network device are unable to transmit data according to the first scheduling information, the terminal device and the network device still have the ability to send and receive data, and therefore can transmit data according to the second scheduling information that is different from the value of at least one scheduling parameter in the first scheduling information, thereby ensuring the smooth transmission of data between the terminal device and the network device, while improving the utilization rate of wireless resources.

[0048] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 The method provided in this application specifically includes the following steps:

[0050] Step 101: The terminal device receives first scheduling information;

[0051] Step 102: The terminal device detects whether part or all of the time domain resources indicated by the first scheduling information are used for full-duplex scheduling or sensing signal transmission; if yes, execute step 103;

[0052] Step 103: The terminal device receives the data channel according to the second scheduling information. Correspondingly, the network device sends the data channel according to the second scheduling information.

[0053] The value of at least one scheduling parameter in the first scheduling information and the second scheduling information is different.

[0054] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0055] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0056] In this embodiment, the network device sends first scheduling information to the terminal device through RRC signaling or DCI, so that the terminal device uses the first scheduling information to transmit data, such as receiving downlink data.

[0057] Specifically, the first scheduling information may include at least one of a first resource indication, a first modulation and coding scheme, a first new data indication, a first redundancy version, and a first antenna port combination; wherein the first resource indication is used to indicate time domain resources.

[0058] That is to say, in the communication standard protocol, it can be stipulated that the first scheduling information includes all of the above scheduling parameters, or it can be stipulated that the first scheduling information includes part of the above scheduling parameters.

[0059] In a specific implementation of step 102, the terminal device may detect whether part or all of the time domain resources indicated by the first scheduling information are used for full-duplex scheduling or perception signal transmission. In other words, the terminal device detects whether part or all of the time domain resources indicated by the first scheduling information include full-duplex symbols, or the terminal device detects whether part or all of the time domain resources indicated by the first scheduling information carry perception signals.

[0060] According to the test results

[0061] If no, it means that the transmission of the current secondary data channel can be completed according to the first scheduling information, and the terminal device uses the first scheduling information to receive the data channel; if yes, it means that part or all of the time domain resources are used for full-duplex scheduling or perception signal transmission, and the transmission of the current secondary data channel cannot be completed according to the first scheduling information, and the terminal device receives the data channel according to the second scheduling information.

[0062] Specifically, the second scheduling information may include at least one of a second modulation and coding scheme, a second new data indication, a second redundancy version, and a second antenna port combination. The scheduling parameter in the second scheduling information that differs from the value in the first scheduling information may be the second modulation and coding scheme and / or the second antenna port combination. In other words, the second modulation and coding scheme may be different from the first modulation and coding scheme, the second antenna port combination may be different from the first antenna port combination, or the second modulation and coding scheme may be different from the first modulation and coding scheme, and the second antenna port combination may also be different from the first antenna port combination.

[0063] Furthermore, the second scheduling information further includes a second resource indication, where the second resource indication is used to indicate a time domain resource, where the time domain resource is used for data channel transmission. The time domain resource indicated by the second resource indication is different from the time domain resource indicated by the first resource indication.

[0064] It should be noted that in actual application scenarios, the values of any other feasible scheduling parameters may be different, which can be specifically implemented by the network device side, and this application does not impose any restrictions on this.

[0065] In a non-limiting embodiment, the network device may also detect whether the time domain resources indicated by the first scheduling information are partially or entirely used for full-duplex scheduling or sensing signal transmission. If so, the network device sends the data channel according to the second scheduling information; otherwise, the network device sends the data channel according to the first scheduling information.

[0066] The configuration method of the second scheduling information is described below in conjunction with different embodiments.

[0067] In a non-limiting example, see Figure 2 In one implementation of step 201, the network device sends a first signaling to the terminal device, where the first signaling includes first scheduling information.

[0068] Specifically, the first signaling may be RRC signaling, DCI, or any other feasible high-layer signaling.

[0069] In this embodiment, the second scheduling information may be a predefined value, for example, may be specified by a communication standard protocol, and this application does not impose any limitation on this.

[0070] In step 202, the terminal device detects whether part or all of the time domain resources indicated by the first scheduling information are used for full-duplex scheduling or sensing signal transmission; if yes, step 203 is executed;

[0071] In step 203, the terminal device receives the data channel according to the second scheduling information. Correspondingly, the network device sends the data channel according to the second scheduling information.

[0072] In another implementation of step 201, the network device sends a first signaling to the terminal device, where the first signaling includes first scheduling information and second scheduling information.

[0073] In this embodiment, the network device sends the first scheduling information and the second scheduling information to the terminal device via the same signaling (i.e., the first signaling). As a result, if the terminal device detects that the time domain resources indicated by the first scheduling information are partially or entirely used for full-duplex scheduling or sensing signal transmission, it receives the data channel according to the second scheduling information. If the terminal device does not detect that the time domain resources indicated by the first scheduling information are partially or entirely used for full-duplex scheduling or sensing signal transmission, it receives the data channel according to the first scheduling information.

[0074] In another non-limiting embodiment, the second scheduling information and the first scheduling information are configured through different signaling.

[0075] Please refer to the Figure 3 In step 301, the network device sends a first signaling to the terminal device, where the first signaling includes first scheduling information.

[0076] In step 302, the network device sends a second signaling to the terminal device, where the second signaling includes second scheduling information.

[0077] In a specific implementation, step 301 and step 302 may be executed simultaneously, or step 301 may be executed first and then step 302; or step 302 may be executed first and then step 301. In this case, the second scheduling information may be pre-configured by the network device for the terminal device.

[0078] In step 303, the terminal device detects whether part or all of the time domain resources indicated by the first scheduling information are used for full-duplex scheduling or sensing signal transmission; if yes, step 304 is executed;

[0079] In step 304, the terminal device receives the data channel according to the second scheduling information. Correspondingly, the network device sends the data channel according to the second scheduling information.

[0080] In a non-limiting embodiment, the data channel between the terminal device and the network device is transmitted multiple times or periodically in the time domain. In this case, the terminal device can determine the time domain resources of each transmission and use the first scheduling information or the second scheduling information to receive the data channel of that transmission.

[0081] In this embodiment, the first scheduling information configured by the network device for the terminal device can schedule multiple transmissions.

[0082] Please refer to the Figure 4 In step 401, the terminal device receives first scheduling information. For each of multiple transmissions scheduled by the first scheduling information, the terminal device performs the following steps 402 to 404.

[0083] In step 402, the terminal device detects whether the time domain resource indicated by the first scheduling information for the current transmission is used for full-duplex scheduling or sensing signal transmission. If yes, step 403 is executed; if not, step 404 is executed.

[0084] In step 403, the terminal device receives the data channel of this transmission according to the second scheduling information.

[0085] In step 404, the terminal device receives the data channel of this transmission according to the first scheduling information.

[0086] Furthermore, in a specific implementation of step 403, the data in the data channel is encoded and resource mapped according to the second scheduling information.

[0087] Specifically, for downlink data, the network device directly performs encoding and resource mapping according to the second scheduling information. Correspondingly, the terminal device directly performs resource mapping and decoding according to the second scheduling information.

[0088] In another specific implementation of step 403, data in the data channel is encoded according to the first scheduling information, and resource mapping is performed according to the second scheduling information.

[0089] In this embodiment, in a scenario of multiple transmissions, the data in the data channel of the initial transmission is encoded according to the first scheduling information, and the encoding operation is relatively complex. Therefore, in order to avoid re-encoding and improve efficiency, in subsequent multiple transmissions based on the second scheduling information, the data channel encoded according to the first scheduling information can continue to be used, and resource mapping can be performed according to the second scheduling information. For example, resource mapping can be performed according to at least one of the second modulation and coding scheme and the second antenna port combination.

[0090] Specifically, for downlink data, the network device encodes according to the first scheduling information and performs resource mapping according to the second scheduling information. Correspondingly, the terminal device performs resource mapping according to the second scheduling information and decodes according to the first scheduling information.
