[0025] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application.

[0027] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0028] It should be understood that the embodiments of the present application are only exemplified by the communication system 100, but the embodiments of the present application are not limited thereto. That is to say, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0029] exist Figure 1 In the communication system 100 shown, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area, and may communicate with the terminal device 110 (eg, UE) located in the coverage area.

[0030] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0031] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0032] For example, the terminal device 110 may refer to an access terminal, a user equipment (UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device.

[0033] The terminal device 110 may be used for device-to-device (D2D) communication.

[0034] The wireless communication system 100 may also include a core network device 130 for communicating with the base station, and the core network device 130 may be a 5G core network (5G Core, 5GC) device, for example, an access and mobility management function (Access and Mobility Management Function, AMF), and for example, an authentication server function (Authentication Server Function, AUSF), and for example, a user plane function (User Plane Function, UPF), and for example, a session management function (Session Management Function, SMF). Optionally, the core network device 130 may also be an evolved packet core (Evolved Packet Core, EPC) device of the LTE network, for example, a session management function + a data gateway (Session Management Function + Core Packet Gateway, SMF + PGW-C) device of the core network. It should be understood that SMF + PGW-C can simultaneously implement the functions that SMF and PGW-C can implement. In the process of network evolution, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited to the embodiments of the present application.

Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0038] It should be understood that all devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 120 and a terminal device 110 with communication functions. The network device 120 and the terminal device 110 may be the devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0039] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0040] Figure 2 2 shows a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, and the method 200 can be executed by a terminal device or a wireless communication device. Figure 1 The terminal device shown, for example, Figure 1 The access network equipment shown.

[0041] like Figure 2 As shown, the method 200 may include:

[0042] S210, determining whether to cancel transmission on the second channel based on the first channel;

[0043] The first channel is determined by at least one initial channel, and the priority of each initial priority channel in the at least one initial channel is higher than the priority of the second channel.

[0044] For example, the terminal device or the network device may determine the first channel based on the at least one initial channel, and then determine whether to cancel transmission of the second channel based on the overlap between the first channel and the second channel. For example, if the first channel and the second channel overlap or partially overlap, determine to cancel transmission of the second channel. If the first channel and the second channel do not overlap, transmit the second channel.

[0045] Determining whether to cancel transmission of the second channel is based on the first channel, and the first channel is determined by at least one initial channel, which is equivalent to determining the first channel used to determine whether to trigger the second channel to cancel transmission based on at least one initial channel. This can ensure that the terminal device and the network device have a consistent understanding of the first channel used to trigger whether to cancel transmission of the second channel, and further, can ensure normal transmission of the channel.

[0046] In some embodiments of the present application, the first channel and the second channel overlap or partially overlap.

[0047] For example, the at least one initial channel and the second channel overlap or partially overlap in the time domain. For example, each initial priority channel in the at least one initial channel and the second channel overlap or partially overlap in the time domain. For another example, some initial priority channels in the at least one initial channel and the second channel overlap or partially overlap in the time domain.

[0048] In some embodiments of the present application, the first scheduling information triggering the first channel is no earlier than the scheduling information corresponding to other channels other than the initial channel corresponding to the first scheduling information in the at least one initial channel.

[0049] For example, the time domain position of the first scheduling information that triggers the first channel is not earlier than the time domain position of the scheduling information corresponding to other channels other than the initial channel corresponding to the first scheduling information in the at least one initial channel.

[0050] For example, the time domain position of the scheduling information may be the time domain position of the downlink scheduling information, or the time domain position determined based on the uplink channel. For example, the time domain position determined based on the uplink channel may be the time domain position of the uplink channel configured semi-statically or semi-persistently.

[0051] In some embodiments of the present application, the first channel is directly scheduled by first scheduling information that triggers the first channel.

[0052] In some embodiments of the present application, the at least one initial channel adopts multiplexing transmission.

[0053] In some embodiments of the present application, the first channel is determined after the at least one initial channel is multiplexed or covered.

[0054] Designing the first channel to be determined after the at least one initial channel is multiplexed or overwritten is equivalent to using the channel determined after the at least one initial channel is multiplexed or overwritten as the first channel for triggering whether to cancel transmission of the second channel. This not only ensures that the terminal device and the network device have a consistent understanding of the first channel used to trigger whether to cancel transmission of the second channel to ensure normal transmission of the channel, but also gives priority to ensuring normal transmission of the at least one initial channel. Accordingly, unnecessary cancellation or information discarding can be avoided, thereby maximizing transmission efficiency.

[0055] In some embodiments of the present application, the S210 may include:

[0056] The second channel is determined to cancel transmission based on the first channel.

[0057] In some embodiments of the present application, the method 200 may further include:

[0058] In the case that the third priority channel and the second channel do not overlap, the second channel is kept to cancel transmission.

[0059] In some embodiments of the present application, the scheduling information triggering the third channel is no earlier than the first scheduling information triggering the first channel.

[0060] In some embodiments of the present application, the S210 may include:

[0061] In the case where the first channel and the second channel overlap, determining that the second channel cancels transmission; and / or

[0062] In a case where the first channel and the second channel do not overlap, the second channel is transmitted.

[0063] In some embodiments of the present application, the at least one initial channel includes a channel indicated by scheduling information and / or a channel determined by the scheduling information.

[0064] For example, the at least one initial channel may be directly indicated by the latest scheduling information and the previous scheduling information, or may be directly determined by the latest scheduling information and indirectly determined by the previous scheduling information. Optionally, the indirect determination may refer to: determining after multiplexing or overlaying the uplink channel directly determined based on the scheduling information.

[0065] In some embodiments of the present application, the channel determined by the scheduling information includes: a channel determined after multiplexing or covering the channel directly determined based on the scheduling information.

[0066] In some embodiments of the present application, the first channel and the second channel are uplink channels.

[0067] In some embodiments of the present application, the uplink channel includes a physical uplink control channel PUCCH and / or a physical uplink shared channel PUSCH.

[0068] In some embodiments of the present application, the time domain position of the first scheduling information that triggers the first channel is the time domain position of the first scheduling information or the time domain position determined based on the first channel.

[0069] In some embodiments of the present application, the time domain position of the first scheduling information is a time domain position determined based on the first channel, and the first channel is an uplink channel configured semi-statically or semi-persistently.

[0070] For example, the symbol before the symbol where the first channel is located may be determined as the time domain position of the first scheduling information.

[0071] The technical solution of the present application is described below in conjunction with Examples 1 to 3.

[0085] Optionally, the first high priority uplink channel has an overlapping portion in the time domain with the first low priority channel and the second high priority uplink channel, and the downlink scheduling information corresponding to the first high priority uplink channel is not earlier than the downlink scheduling information corresponding to the second high priority uplink channel.

[0086] Optionally, whether to cancel transmission of the first priority uplink channel may be determined based on the third highest priority uplink channel, wherein the third highest priority uplink channel is determined by multiplexing the first high priority uplink channel and the second high priority channel.

[0087] For example, if the third highest priority uplink channel overlaps with the first low priority channel in the time domain, the transmission of the first priority uplink channel is canceled; if the third highest priority uplink channel does not overlap with the first low priority channel in the time domain, the first priority uplink channel can be transmitted.

[0088] Optionally, the uplink channel can be PUCCH / PUSCH

[0091] Optionally, the uplink channel may be directly indicated by scheduling information, or may be determined by multiplexing of multiple uplink channels of the same priority.

[0092] Embodiment 3:

[0093] Optionally, if there is an overlap between the first high-priority uplink channel and the first low-priority channel in the time domain, the transmission of the first low-priority channel is canceled.

[0094] Optionally, there is no overlapping portion between the second high priority uplink channel and the first low priority channel in the time domain, and the transmission of the first low priority channel is still canceled.

[0095] Optionally, the time domain position of the scheduling information corresponding to the second highest priority uplink channel is not earlier than the time domain position of the scheduling information corresponding to the first highest priority uplink channel.

[0096] Optionally, information may be sent or received on the second highest priority uplink channel.
