It can be seen that, in this embodiment, the terminal device determines whether to perform multiplexing transmission on the N first uplink information and the M second uplink information only according to the first indication information included in the first downlink control information that is received last, without paying attention to other first downlink control information, which increases the scheduling flexibility and the fault tolerance rate of the network device.

In some possible embodiments, the determining, according to the first indication information included in the third downlink control information, whether to multiplex the N first uplink information and the M second uplink information includes: and when the first indication information included in the third downlink control information is a first preset value, determining that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be understood that when at least one value of the N pieces of first indication information is not a first preset value, it is determined that multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information cannot be performed.

It can be seen that, in this embodiment, when all the first uplink information is scheduled by downlink control information, the terminal device determines whether to multiplex the N first uplink information and the M second uplink information according to all the first indication information, and since all the first indication information is used, the determination result can be more accurate.

In some possible embodiments, the N first uplink messages are configured by N first higher layer parameters, each first higher layer parameter including one of the N first indication messages; the determining whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to part or all of the N first indication information includes: and when the values of the N pieces of first indication information are all first preset values, determining that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be seen that, in this embodiment, when all the first uplink information is configured by the higher layer parameter, the terminal device determines whether to multiplex the N first uplink information with the M second uplink information according to all the first indication information, and since all the first indication information is used, the determination result can be more accurate.

In some possible embodiments, X first uplink information of the N first uplink information is scheduled by X first downlink control information, and the remaining Y first uplink information is configured by Y first higher layer parameters, where each of the first downlink control information and each of the first higher layer parameters respectively include one first indication information, and X + Y = N, and X and Y are integers greater than or equal to 1; the determining whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to part or all of the N first indication information includes: and determining whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to first indication information included in fourth downlink control information, where the fourth downlink control information is the first downlink control information that is received by the terminal device last in the X pieces of first downlink control information. And when first indication information included in the fourth downlink control information is a first preset value, determining that the N first uplink information and the M second uplink information are subjected to multiplexing transmission. And when the first indication information included in the third downlink control information is not a first preset value, determining that the multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information cannot be performed.

It can be seen that, in this embodiment, the terminal device determines whether to perform multiplexing transmission on the N first uplink messages and the M second uplink messages only according to the first indication information included in the last received downlink control message, so that the scheduling of the network device is relatively flexible, and the fault tolerance of the network device is improved.

In some possible embodiments, X first uplink information of the N first uplink information is scheduled by X first downlink control information, and the remaining Y first uplink information is configured by Y first higher layer parameters, where each of the first downlink control information and each of the first higher layer parameters respectively include one first indication information, and X + Y = N, and X and Y are integers greater than or equal to 1; the determining whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to part or all of the N first indication information includes: when the values of the X first indication information respectively included in the X first downlink control information are all first preset values, determining that the N first uplink information and the M second uplink information are subjected to multiplexing transmission; when at least one value of first indication information of X first indication information respectively included by X first downlink control information is not a first preset value, determining that multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed; or when the values of the X first indication information included in the X first downlink control information are all first preset values, and the values of the Y first indication information included in the Y first high-level parameters are all first preset values, determining to perform multiplexing transmission on the N first uplink information and the M second uplink information. When at least one value of the indication information is not a first preset value in X first indication information included in the X first downlink control information and Y first indication information included in the Y first high-level parameters, it is determined that the N first uplink information and the M second uplink information cannot be multiplexed.

It can be seen that, in this embodiment, the terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to first indication information included in all downlink control information; or, according to all the first indication information, determining whether to multiplex and transmit the N first uplink information and the M second uplink information, so that the determination result is relatively accurate.

In some possible embodiments, the N first uplink messages are configured by N first uplink parameters, and Z second uplink messages in the M second uplink messages are scheduled by Z second downlink control messages, where each first uplink parameter includes a first indication message, each second downlink control message includes a second indication message, and Z is less than or equal to M; the determining whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to the N first indication information and/or the M second indication information includes: and determining whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to part or all of the Z pieces of second indication information included in the Z pieces of second downlink control information respectively.

It can be seen that, in this embodiment, the terminal device may not distinguish priorities of the first uplink channel and the second uplink channel, may preferentially consider the indication information corresponding to the uplink information scheduled by the downlink control information, and determine whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information according to the indication information. Under the condition of not distinguishing the priority, the method for scheduling the uplink information by the downlink control information is more flexible, so that the accuracy of the determination result is higher.

Optionally, the terminal device may determine whether to perform multiplexing transmission on the N first uplink messages and the M second uplink messages according to second indication information in fifth downlink control information, where the fifth downlink control information is the first downlink control information that is received by the terminal device last in the Z second downlink control information. That is, when the value of the second indication information in the fifth downlink control information is the first preset value, it is determined that the N first uplink information and the M second uplink information are subjected to multiplexing transmission. And when the value of the second indication information in the fifth downlink control information is not the first preset value, determining that the N pieces of first uplink information and the M pieces of second uplink information cannot be subjected to multiplexing transmission.

Optionally, the terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to all values of the Z second indication information. When the values of the Z second indication information respectively included in the Z second downlink control information are all first preset values, determining that the N first uplink information and the M second uplink information are subjected to multiplexing transmission; and when the value of at least one first indication information of the Z second indication information respectively included by the Z second downlink control information is not a first preset value, determining that the N first uplink information and the M second uplink information cannot be subjected to multiplexing transmission.

In some possible embodiments, the priority of the first uplink channel is higher than the priority of the second uplink channel.

It can be seen that, in the present embodiment, even if the terminal device determines that the priority of the first uplink channel is higher than the priority of the second uplink channel, since all the first uplink information is configured by the higher-layer parameter, it is relatively fixed; and the second uplink information has downlink control information scheduling, and the scheduling mode is more flexible. Therefore, even if the priority of the first uplink channel is high, it is necessary to determine whether to multiplex the N first uplink information and the M second uplink information using the second indication information included in the downlink control information, and the accuracy of the determination result can be made high.

In some possible embodiments, L first uplink information of the N first uplink information is scheduled by L first downlink control information, and R second uplink information of the M second uplink information is scheduled by R second downlink control information, where L and R are integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; the determining, according to the N first indication information corresponding to the first uplink channel and/or the M second indication information corresponding to the second uplink channel, whether to perform multiplexing transmission on the N first uplink information and the M second uplink information includes: determining whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to third indication information contained in fifth downlink control information; the fifth downlink control information is downlink control information that is received by the terminal device last in the L pieces of first downlink control information and the R pieces of second downlink control information, and the third indication information is the first indication information or the second indication information.

It can be understood that when a value of third indication information included in the fifth downlink control information is a first preset value, it is determined that the N first uplink information and the M second uplink information are subjected to multiplexing transmission; and when the value of the third indication information included in the fifth downlink control information is not a first preset value, determining that the N first uplink information and the M second uplink information cannot be subjected to multiplexing transmission.

It can be seen that, without prioritizing, whether to multiplex the N first uplink messages with the M second uplink messages may be determined according to indication information included in downlink control information, and whether to multiplex the N first uplink messages with the M second uplink messages may be determined only by using indication information included in downlink control information received last by a terminal device, thereby improving flexibility of network device indication and fault tolerance.

In some possible embodiments, L first uplink information of the N first uplink information is scheduled by L first downlink control information, and R second uplink information of the M second uplink information is scheduled by R second downlink control information, where L and R are integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; the determining, according to the N pieces of first indication information corresponding to the first uplink channel and/or the M pieces of second indication information corresponding to the second uplink channel, whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information includes: when the values of the L first indication information included in the L first downlink control information are all first preset values, and the values of the R second indication information included in the R first downlink control information are all first preset values, determining that the N first uplink information and the M second uplink information are subjected to multiplexing transmission.

It can be understood that when at least one value of L first indication information included in L first downlink control information and R second indication information included in R first downlink control information is not a first preset value, it is determined that the N first uplink information and the M second uplink information cannot be multiplexed.

It can be seen that, in this embodiment, under the condition that priorities are not distinguished, the terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to indication information included in all downlink control information, so as to improve accuracy of a determination result.

In some possible embodiments, the N first uplink messages are configured by N first upper layer parameters, and the M second uplink messages are configured by M second upper layer parameters, where each first upper layer parameter includes a first indication message, and each second upper layer parameter includes a second indication message; the determining, according to the N first indication information corresponding to the first uplink channel and/or the M second indication information corresponding to the second uplink channel, whether to perform multiplexing transmission on the N first uplink information and the M second uplink information includes: and when the values of the N pieces of first indication information contained in the N pieces of first high-level parameters are all first preset values, and the values of the M pieces of second indication information contained in the M pieces of second high-level parameters are all first preset values, determining that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be seen that, in this embodiment, in the case where priority is not prioritized and all the first indication information and all the second indication information are used for higher layer parameter scheduling, the terminal device determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information, and thus, the accuracy of the determination result can be ensured.

In some possible embodiments, the determining, according to N first indication information corresponding to the first uplink channel and/or M second indication information corresponding to the second uplink channel, whether to multiplex the N first uplink information and the M second uplink information includes: and when the values of the N pieces of first indication information are all first preset values, and the values of the M pieces of second indication information are all first preset values, determining that multiplexing transmission is performed on the N pieces of first uplink information and the M pieces of second uplink information.

Therefore, the terminal equipment can determine whether to carry out multiplexing transmission according to all the acquired indication information, and the determination result can be more accurate due to the use of all the indication information.

In a second aspect, an embodiment of the present application provides a method for uplink transmission, where the method is applied to a network device, and the method includes: sending N pieces of first indication information, wherein the N pieces of first indication information correspond to N pieces of first uplink information, and the N pieces of first uplink information are borne on a first uplink channel; sending M pieces of second indication information, wherein the M pieces of second indication information correspond to M pieces of second uplink information, and the M pieces of second uplink information are borne on a second uplink channel; the N pieces of first indication information and/or the M pieces of second indication information are used to indicate whether to multiplex the N pieces of first uplink information and the M pieces of second uplink information; the priorities of the first uplink channel and the second uplink channel are different, and the time domains of the first uplink channel and the second uplink channel are overlapped; n and M are integers greater than or equal to 1.

It can be seen that, under the condition that uplink transmissions of the terminal devices overlap, the network device may indicate, through the N pieces of first indication information and/or the M pieces of second indication information, whether the terminal device performs multiplexing transmission or not, instead of simply specifying the terminal device to perform multiplexing transmission or abandon multiplexing transmission, thereby ensuring flexibility of the terminal device in performing multiplexing transmission or abandoning multiplexing transmission, and further not bringing a delay to transmission of a high-priority service, and not reducing transmission efficiency of a low-priority service.

In some possible embodiments, the priority of the first uplink channel is higher than the priority of the second uplink channel; and part or all of the N pieces of first indication information are used for indicating whether the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplex transmission.

It can be seen that, in this embodiment, the network device may only indicate, through the indication information corresponding to the first uplink channel with high priority, whether the terminal device performs multiplexing transmission, without paying attention to the second uplink channel, and therefore, transmission of the uplink channel with high priority may be better guaranteed.

In some possible embodiments, the N first uplink information are scheduled by N first downlink control information, each first downlink control information including one of the N first indication information; the third downlink control information includes first indication information used for indicating whether to multiplex the N first uplink information and the M second uplink information, where the third downlink control information is the first downlink control information that is received by the terminal device last in the N first downlink control information.

It can be seen that, in this embodiment, the network device indicates, through the first indication information included in the first downlink control information that is received by the terminal device last, whether the terminal device performs multiplexing transmission, without paying attention to other first downlink control information corresponding to the first uplink channel, so that flexibility and fault tolerance rate of a scheduling process of the network device are increased.

In some possible embodiments, the first indication information included in the third downlink control information is a first preset value, and is used to indicate that the N first uplink information and the M second uplink information are subjected to multiplexing transmission.

It can be understood that, if the first indication information included in the third downlink control information is not the first preset value, it indicates that the multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

In some possible embodiments, the N first uplink information are scheduled by N first downlink control information, each first downlink control information including one of the N first indication information; and the values of the N pieces of first indication information are all first preset values and are used for indicating that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be understood that, in the N pieces of first indication information, at least one value of the first indication information is not a first preset value, and may be used to indicate that multiplexing transmission cannot be performed on the N pieces of first uplink information and the M pieces of second uplink information.

It can be seen that, in this embodiment, when all the first uplink information is scheduled by downlink control information, the network device instructs the terminal device to indicate whether to multiplex the N first uplink information and the M second uplink information according to values of all the first indication information. Because all the values of the first indication information are used for indicating, the indicating result can be more accurate.

In some possible embodiments, the N first uplink messages are configured by N first higher layer parameters, each first higher layer parameter including one of the N first indication messages; and the values of the N pieces of first indication information are all first preset values and are used for indicating that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be understood that, in the N pieces of first indication information, at least one value of the indication information is not a first preset value, and may be used to indicate that multiplexing transmission cannot be performed on the N pieces of first uplink information and the M pieces of second uplink information.

It can be seen that, in this embodiment, when all the first uplink information is configured by the higher layer parameter, the network device indicates, by using values of all the first indication information, whether to multiplex the N first uplink information with the M second uplink information, and since the indication is performed by using values of all the first indication information, the indication result can be more accurate.

In some possible embodiments, X first uplink information of the N first uplink information is scheduled by X first downlink control information, and the remaining Y first uplink information is configured by Y first higher layer parameters, where each first downlink control information and each first higher layer parameter respectively include one first indication information, where X + Y = N, and X and Y are integers greater than or equal to 1; the fourth downlink control information includes first indication information used to indicate whether to multiplex the N first uplink information and the M second uplink information, where the fourth downlink control information is the first downlink control information that is received by the terminal device last in the X first downlink control information. The first indication information included in the fourth downlink control information is a first preset value, and is used for indicating that the N first uplink information and the M second uplink information are subjected to multiplexing transmission. And the first indication information included in the third downlink control information is not a first preset value, and is used for indicating that the multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

It can be seen that, in this embodiment, the network device indicates, through the first indication information included in the downlink control information received by the terminal device last, whether to perform multiplexing transmission on the N first uplink information and the M second uplink information, without paying attention to other indication information, so that the indication of the network device is relatively flexible, and the fault tolerance of the network device is improved.

In some possible embodiments, X first uplink information of the N first uplink information is scheduled by X first downlink control information, and the remaining Y first uplink information is configured by Y first higher layer parameters, where each first downlink control information and each first higher layer parameter respectively include one first indication information, where X + Y = N, and X and Y are integers greater than or equal to 1; optionally, values of X first indication information included in the X first downlink control information are all first preset values, and are used to indicate that the N first uplink information and the M second uplink information are subjected to multiplexing transmission; optionally, at least one value of the first indication information, which is not a first preset value, exists in the X first indication information included in each of the X first downlink control information, and the X first indication information is used for indicating that the N first uplink information and the M second uplink information cannot be multiplexed; or values of X first indication information included in each of the X first downlink control information are all first preset values, and values of Y first indication information included in each of the Y first high-level parameters are all the first preset values, and are used to indicate that the N first uplink information and the M second uplink information are multiplexed. Optionally, in X first indication information included in each of the X first downlink control information and Y first indication information included in each of the Y first high-level parameters, at least one value of the indication information is not a first preset value, and is used to indicate that multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

It can be seen that, in this embodiment, the network device may indicate, through values of first indication information included in all the first downlink control information, whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information; or, whether the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission is indicated through values of all the pieces of first indication information, and therefore an indication result is accurate.

In some possible embodiments, the N first uplink messages are configured by N first uplink parameters, and Z second uplink messages in the M second uplink messages are scheduled by Z second downlink control messages, where each first uplink parameter includes a first indication message, each second downlink control message includes a second indication message, and Z is less than or equal to M; and part or all of the Z second indication information included in the Z second downlink control information is used for indicating whether to multiplex and transmit the N first uplink information and the M second uplink information.

Optionally, the network device may indicate, through second indication information in fifth downlink control information, whether to perform multiplexing transmission on the N first uplink information and the M second uplink information, where the fifth downlink control information is the first downlink control information that is received by the terminal device last in the Z second downlink control information. That is, when a value of second indication information in the fifth downlink control information is a first preset value, the N first uplink information and the M second uplink information are indicated to be multiplexed and transmitted. And when the value of second indication information in the fifth downlink control information is not a first preset value, indicating that the N pieces of first uplink information and the M pieces of second uplink information cannot be subjected to multiplexing transmission.

Optionally, the network device may indicate whether to multiplex the N first uplink information and the M second uplink information through all values of the Z second indication information. When the values of the Z second indication information respectively included in the Z second downlink control information are all first preset values, indicating that the N first uplink information and the M second uplink information are subjected to multiplex transmission; and when the value of at least one first indication information of the Z second indication information respectively included by the Z second downlink control information is not a first preset value, indicating that the N first uplink information and the M second uplink information cannot be subjected to multiplexing transmission.

It can be seen that, in this embodiment, the network device instructs the terminal device not to distinguish priorities of the first uplink channel and the second uplink channel, and may prioritize the indication information corresponding to the uplink information scheduled by the downlink control information, and instruct the terminal device to determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to the indication information. Because the terminal equipment does not need to distinguish priority, the mode that the network equipment schedules the uplink information through the downlink control information is more flexible, and the precision of the determination result can be higher.

It can be seen that, in this embodiment, the network device instructs the terminal device to determine that the priority of the first uplink channel is higher than the priority of the second uplink channel, but since all the first uplink information is configured by the higher layer parameter, the first uplink information is relatively fixed; and the second uplink information has downlink control information scheduling, and the scheduling mode is more flexible. Therefore, even if the priority of the first uplink channel is high, the network device instructs the terminal device to determine whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information using the second indication information included in the downlink control information, so that the accuracy of the instruction result can be high.

In some possible embodiments, L first uplink information of the N first uplink information is scheduled by L first downlink control information, and R second uplink information of the M second uplink information is scheduled by R second downlink control information, where L and R are integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; third indication information included in fifth downlink control information, configured to indicate whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information; the fifth downlink control information is downlink control information that is received by the terminal device last in the L pieces of first downlink control information and the R pieces of second downlink control information, and the third indication information is the first indication information or the second indication information.

It can be understood that when a value of third indication information included in the fifth downlink control information is a first preset value, the N first uplink information and the M second uplink information are indicated to be subjected to multiplexing transmission; and when the value of the third indication information included in the fifth downlink control information is not a first preset value, indicating that multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

It can be seen that, under the condition of not prioritizing, the network device instructs the terminal device to determine whether to multiplex the N first uplink messages with the M second uplink messages according to the indication information included in the downlink control information, and the terminal device may determine whether to multiplex the N first uplink messages with the M second uplink messages by using the indication information included in the downlink control information received last, thereby improving the flexibility of network device indication and the fault tolerance.

In some possible embodiments, L first uplink information of the N first uplink information is scheduled by L first downlink control information, and R second uplink information of the M second uplink information is scheduled by R second downlink control information, where L and R are integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; when values of L pieces of first indication information included in the L pieces of first downlink control information are all first preset values, and values of R pieces of second indication information included in the R pieces of first downlink control information are all the first preset values, indicating that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be understood that when at least one value of L first indication information included in L first downlink control information and R second indication information included in R first downlink control information is not a first preset value, it indicates that the N first uplink information and the M second uplink information cannot be multiplexed.

It can be seen that, in this embodiment, the network device instructs the terminal device to determine whether to multiplex the N first uplink information and the M second uplink information according to the values of the indication information included in all the downlink control information without differentiating the priority, so as to improve the accuracy of the instruction.

In some possible embodiments, the N first uplink messages are configured by N first upper layer parameters, and the M second uplink messages are configured by M second upper layer parameters, where each first upper layer parameter includes a first indication message, and each second upper layer parameter includes a second indication message; and when the values of the N pieces of first indication information contained in the N pieces of first high-level parameters are all first preset values, and the values of the M pieces of second indication information contained in the M pieces of second high-level parameters are all first preset values, indicating that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission.

It can be seen that, in this embodiment, when the network device instructs the terminal device not to prioritize but to perform higher layer parameter scheduling, whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information is determined according to values of all pieces of first indication information and all pieces of second indication information, so that accuracy of the instruction can be ensured.

In some possible embodiments, when the values of the N first indication information are all the first preset values, and the values of the M second indication information are all the first preset values, indicating that the N first uplink information and the M second uplink information are to be subjected to multiplexing transmission.

Therefore, the network equipment indication terminal equipment can determine whether multiplex transmission is carried out or not according to the obtained values of all the indication information, and the indication borrowing result can be more accurate due to the fact that indication is carried out by using the values of all the indication information.

Detailed Description

The technical scheme in the embodiment of the application can be applied to various communication systems. For example, fifth generation (5 g) mobile communication systems and future mobile communication systems.

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

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

While the various UEs described above, if located on a vehicle (e.g., placed in or installed in the vehicle), may be regarded as vehicle-mounted user equipment (e.g., also referred to as an on-board unit (OBU)), which is not limited in this embodiment of the present application.

To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.

In order to better support multiplexing transmission of hybrid services, in the protocol version of the third Generation Partnership project (3 rd Generation Partnership project,3 gpp) Release16, division of physical layer priorities is introduced, uplink information may be divided into High Priority (HP) uplink information or Low Priority (LP) uplink information according to corresponding service types, and correspondingly, uplink channels carrying the uplink information may also be divided into High priority uplink channels and Low priority uplink channels. If a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) with the same priority are overlapped, uplink information carried in the PUCCH and the PUSCH can be directly multiplexed and transmitted; if the uplink channels with different priorities are overlapped, multiplexing transmission of the carried uplink information is not allowed, and the uplink information carried by the uplink channel with low priority needs to be abandoned at the overlapped time domain resource position, and only the uplink information carried by the uplink channel with high priority is transmitted. However, if the transmission of the low-priority uplink channel does not affect the transmission of the high-priority uplink channel, the multiplexing transmission is directly abandoned, which may affect the transmission efficiency of the low-priority uplink channel. On the contrary, if the multiplexing transmission is directly performed, a transmission delay may be caused to the transmission of the uplink channel with high priority, which reduces the transmission efficiency and affects the transmission reliability.

It can be understood that, in the present application, the uplink information carried in one uplink channel has the same physical layer priority, and therefore the priority of the uplink channel can be characterized by the priority of the uplink information carried in the uplink channel. Correspondingly, the different priorities of the uplink channels also mean that the priorities of the uplink information carried by the uplink channels are different. In this way, the priority of the uplink channel #1 is higher than that of the uplink channel #2, and equivalently, the priority of the uplink information #1 carried by the uplink channel #1 is higher than that of the uplink information #2 carried by the uplink channel # 2. That is to say, the uplink information carried by the uplink channels with different priorities or the uplink channels with different priorities has a priority ranking, that is, the uplink information includes the uplink information with high priority and the uplink information with low priority.

Referring to fig. 1, as shown in the left diagram of fig. 1, the first PUCCH (PUCCH 1) is an HP PUCCH, the second PUCCH (PUCCH 2) is an LP PUCCH, and since the terminal device still has an idle time domain resource before transmitting the HP UCI carried by the HP PUCCH, at this time, LP Uplink Control Information (UCI) carried by the LP PUCCH and the HP UCI carried by the HP PUCCH may be multiplexed, and the joint uplink control information (joint UCI) is carried on the third PUCCH (PUCCH 3) for transmission, which does not cause a delay to the transmission of the HP UCI carried by the HP PUCCH. However, if the multiplexing transmission is abandoned at this time, the transmission efficiency of the LP UCI carried by the LP PUCCH may be affected. As shown in the right diagram of fig. 1, there may be no idle time domain resource before transmitting the HP UCI carried by the HP PUCCH, and at this time, the LP UCI carried by the LP PUCCH and the HP UCI carried by the HP PUCCH are multiplexed onto PUCCH3 for transmission, and the end time of the multiplexed transmission is greater than the end time of the HP PUCCH. Therefore, if uplink information carried by the LP PUCCH and the HP PUCCH is directly multiplexed and transmitted, a delay may be brought to transmission of the HP UCI carried by the HP PUCCH, which affects transmission efficiency of the HP service.

In summary, the terminal device has a single mode of performing multiplexing transmission or discarding multiplexing transmission, which affects transmission efficiency.

The related concepts related to the present application will be first presented to facilitate an understanding of the present application.

1. And (4) classification of uplink channels.

The uplink channel includes PUCCH and PUSCH. The PUCCH is used for bearing uplink control information UCI, and the PUSCH is used for bearing the uplink control information UCI and/or data. Wherein the UCI comprises at least one of:

hybrid Automatic Repeat Request (HARQ) -acknowledgement or negative acknowledgement (ACK/NACK), abbreviated as HARQ-ACK, channel State Information (CSI), of a Physical Downlink Shared Channel (PDSCH), and the CSI includes Periodic (P) -CSI, semi-Persistent (SP) -CSI, and Aperiodic (a) -CSI, scheduling Request (SR), beam Failure Recovery (BFR).

2. And scheduling mode of uplink information.

The scheduling mode of the uplink information comprises the following three types: downlink Control Information (DCI) scheduling, higher layer parameter configuration, and higher layer parameter configuration, but DCI activation is required.

2.1, when the transmission of the uplink information is DCI scheduling, the uplink information includes at least one of the following:

HARQ-ACK of PDSCH scheduled by DCI, uplink data and DCI triggered A-CSI, including A-CSI on PUCCH and A-CSI on PUSCH.

2.2, under the condition that the transmission of the uplink information is configured by the high-layer parameters, the uplink information includes at least one of the following:

SR, the corresponding high-level parameter is the PUCCH resource configuration parameter of the SR;

BFR, the corresponding high-level parameter is PUCCH resource configuration parameter of the BFR;

the data is carried in a Type-1CG PUSCH, the Type-1CG PUSCH is a first Type (Type-1) in a configuration authorized (CG) -PUSCH, and the corresponding high-level parameter is a Type-1CG configuration parameter.

2.3, when the transmission of the uplink information is higher-layer parameter configuration but DCI activation is required, the uplink information includes at least one of the following:

data carried in a Type-2 CG PUSCH, wherein the Type-2 CG PUSCH is a first Type (Type-2) in the CG-PUSCH, and a corresponding high-level parameter is a Type-2 CG configuration parameter;

the corresponding high-level parameters are SP CSI report configuration parameters;

Semi-Persistent Scheduling (SPS) -HARQ-ACK of PDSCH, and the corresponding high-level parameter is an SPS configuration parameter, i.e., SPS Config.

3. And indicating the priority of the uplink information.

3.1, HARQ-ACK of PDSCH scheduled by DCI: the network equipment indicates the priority of HARQ-ACK by adding a priority indicator (priority indicator) field of 1bit in the DCI;

3.2, HARQ-ACK of SPS-PDSCH: the network device indicates the priority of the SPS-PDSCH by adding a 1-bit priority Indicator in the SPS configuration parameter (i.e., SPS Config);

it should be noted that the SPS PDSCH is activated through DCI, and this DCI for activation also has a 1-bit priority indicator field, but this field is automatically disabled and does not override the priority indicated in the SPS Config.

3.3, SR or BFR: the network equipment indicates the priority of the SR or the BFR by adding a 1-bit priority Indicator parameter in a radio resource control parameter of the PUCCH resource corresponding to the SR or the BFR;

3.4, CSI on PUCCH: for both P-CSI and SP-CSI, low priority is defaulted; for an A-CSI on PUCCH, the network equipment indicates the priority of the priority A-CSI by triggering a 1-bit priority indicator in the DCI of the A-CSI.

3.5, DCI scheduled PUSCH, GB (Grant-based) -PUSCH for short: the network device indicates the priority of the GB-PUSCH by adding a priority indicator field of 1bit to the DCI.

3.6, CG-PUSCH: the network device indicates the priority by adding a 1-bit priority Indicator parameter to the CG configuration information (CG Config).

It should be noted that CG PUSCHs are classified into Type 2, type-1CG PUSCH and Type-2 CG PUSCH, type-1CG PUSCH is completely transmitted by RRC parameter configuration, type-2 CG PUSCH is activated by DCI, and there is a 1-bit priority indicator field in the activated DCI, but the field is automatically disabled, and the priority indicated in CG Config is not rewritten.

3.7, SP-CSI or A-CSI on PUSCH: the network equipment indicates the priority of the GB-PUSCH by triggering the priority indicator field of 1bit added in the DCI of the SP-CSI or the A-CSI.

The technical solution of the present application is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating an architecture of a communication system according to an embodiment of the present disclosure. The communication system 10 includes a terminal device 100 and a network device 200. The terminal device 100 obtains first indication information, where the first indication information corresponds to N first uplink information, and the N first uplink information is carried in a first uplink channel; the terminal device 100 further obtains M pieces of second indication information, where the M pieces of second indication information correspond to M pieces of second uplink information, and the M pieces of second uplink information are carried in a second uplink channel; the terminal device 100 determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the N pieces of first uplink information and/or the M pieces of second uplink information; the priority of the first uplink channel is different from that of the second uplink channel, the time domains of the first uplink channel and the second uplink channel are overlapped, the overlapped time domain resources are first time domain resources, and both N and M are integers greater than or equal to 1.

Optionally, the first indication information may be included in a first DCI or a first higher layer parameter sent by the network device 200 to the terminal device 100, where the first DCI is used to schedule transmission of the first uplink information, and the first higher layer parameter is used to configure transmission of the first uplink information, and may be Radio Resource Control (RRC) signaling. And the first indication information corresponding to the first uplink information is used for indicating whether the uplink information can be subjected to multiplexing transmission with uplink information with different priorities.

Optionally, the second indication information may be included in a second DCI or a second higher layer parameter sent by the network device 200 to the terminal device 100, where the second DCI is used to schedule transmission of the second uplink information, and the second higher layer parameter is used to configure transmission of the second uplink information and may be RRC signaling. And the second indication information corresponding to one second uplink information is used for indicating whether the uplink information can be multiplexed with uplink information with different priorities.

Optionally, the priority of the first uplink channel is the priority of the N first uplink information, and the N first uplink information have the same priority.

Optionally, the priority of the second uplink channel is the priority of the M second uplink information, and the M second uplink information has the same priority.

Optionally, the priority refers to a physical layer priority, and is used to implicitly indicate a service type corresponding to the uplink information or a delay or reliability requirement of a service.

Optionally, the time domain of the first uplink channel overlaps with the time domain of the second uplink channel, which means that the time domain resource of the first uplink channel and the time domain resource of the second uplink channel include at least one same time unit, and the time unit may be a time slot and/or a symbol. For example, if the time domain resource of the first uplink channel is symbols #1 to #6 in slot #3, the time domain resource of the second uplink channel is symbols #4 to #9 in slot #3, and the time units are symbols, the same time units contained in the two are symbols #4 to #6 in slot # 3. Correspondingly, the overlapping time domain resource, i.e. the first time domain resource, corresponds to symbols #4 to #6 in slot # 3.

When the terminal device 100 determines to multiplex the N first uplink information and the M second uplink information, the terminal device performs multiplexing transmission on the N first uplink information and the M second uplink information, including multiplexing the N first uplink information and the M second uplink information, and sends the multiplexed combined uplink information to the network device 200 on the third uplink channel. The third uplink channel may be one of the first uplink channel and the second uplink channel, or another uplink channel different from the first uplink channel and the second uplink channel. The third uplink channel determination method may be any determination method, which is not particularly limited in this application.

When the terminal device 100 determines that the N first uplink information and the M second uplink information cannot be multiplexed for transmission, the first uplink information carried by the first uplink channel is sent to the network device 200 at the first time domain resource location, and the sending of the second uplink channel to the network device 200 is abandoned at the first time domain resource location, where the priority of the first uplink channel is higher than that of the second uplink channel. Optionally, the step of giving up sending the second uplink channel to the network device 200 at the first time domain resource location may also be represented as not sending the second uplink channel or canceling the sending of the second uplink channel at the first time domain resource location. Optionally, the second uplink channel is discarded, sent/not sent/canceled in the first time domain resource location, and part or all of the second uplink information originally carried on the first time domain resource and the second uplink channel may also be discarded, sent/not sent/canceled.

It can be seen that, in this embodiment of the present application, the terminal device 200 determines whether multiplexing transmission can be performed on the N first uplink information and the M second uplink information according to the N first indication information corresponding to the N first uplink information and/or the M second indication information corresponding to the M second uplink information, instead of performing multiplexing transmission or abandoning multiplexing transmission directly, so as to improve flexibility of the terminal device in the process of performing multiplexing transmission or abandoning multiplexing transmission, which can not only avoid that the multiplexing transmission affects delay and reliability of high-priority service transmission, but also improve transmission efficiency of low-priority service.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for uplink transmission according to an embodiment of the present disclosure. The method comprises the following steps:

301: the terminal equipment acquires N pieces of first indication information, wherein the N pieces of first indication information correspond to N pieces of first uplink information, and the N pieces of first uplink information are borne on a first uplink channel.

Illustratively, the first uplink channel comprises a first PUCCH or a first PUSCH. Each of the N first uplink information may be a first UCI or data (data). Wherein the first UCI comprises at least one of: HARQ-ACK, P-CSI, SP-CSI, A-CSI, SR, and BFR.

Illustratively, the uplink information scheduling method includes three types: the network device is configured (1) by DCI scheduling, (2) by higher layer parameters, and (3) by higher layer parameters, but needs DCI activation. Therefore, the N first uplink messages may be obtained by the network device through scheduling in one or more of the three scheduling manners, and each scheduling manner may include the first indication message; then, the terminal device obtains the N first indication information according to a scheduling manner of the network device for the N first uplink information.

It should be noted that, for the higher layer parameter configuration, but the scheduling method that requires DCI activation, the first indication information included in the scheduling method may be the first indication information included in the DCI used during activation, or the first indication information included in the higher layer configuration parameter, which is not limited herein. That is, in the following description, "the network device performs scheduling via DCI" includes "the network device performs scheduling via DCI" and/or "the network device performs configuration via higher-layer parameters but requires DCI activation", "the network device performs configuration via higher-layer parameters" includes "the network device performs configuration via higher-layer parameters" and/or "the network device performs configuration via higher-layer parameters but requires DCI activation".

The following describes in detail a manner in which the terminal device acquires the N pieces of first indication information with reference to a specific scheduling manner.

(1) Case 1: the N first uplink information are scheduled by the network device through the N first DCI.

Illustratively, all of the N first uplink information are scheduled by the network device through N first DCIs, where each first DCI includes one first indication information. For example, a field may be added to each first DCI, and the field carries the first indication information; alternatively, one existing field in each first DCI may be multiplexed, and the first indication information may be carried through the field. The first indication information may be used to indicate whether uplink information scheduled by the DCI may be multiplexed with uplink information of different priorities. Therefore, the terminal device may obtain the N first indication information by analyzing a new or existing field in each first DCI.

(2) Case 2: the N first uplink messages are configured by N first higher layer parameters.

Illustratively, all of the N first uplink messages are configured by the network device through N first higher layer parameters, where each of the first higher layer parameters includes a first indication message. For example, a field may be added to each first higher layer parameter, and the first indication information is carried by the field. Alternatively, an existing field in each first higher layer parameter may be multiplexed, through which the first indication information is carried. Therefore, the terminal device may obtain the N pieces of first indication information by analyzing a new or existing field in each of the first high level parameters. The first indication information may be used to indicate whether uplink information carried by an uplink channel configured by the higher layer parameter can be multiplexed with uplink information of different priorities. Here, the higher layer parameter may be RRC signaling, and a field included in the higher layer parameter may be an Information element (Information element) in the RRC signaling.

(3) Case 3: x first uplink information in the N first uplink information is scheduled by the network device through X first DCI, and the remaining Y first uplink information are configured by the network device through Y first high-layer parameters, where X + Y = N, and X and Y are integers greater than or equal to 1.

Illustratively, a part of the first uplink information in the N first uplinks, that is, X first uplink information, is scheduled by the network device through X first DCIs, where each first DCI includes one first indication information; another part of the first uplink information, that is, Y pieces of first uplink information, is configured by the network device through Y pieces of first higher-layer parameters.

Wherein, the X first uplink information and the X first indication information acquisition methods are similar to the first indication information acquisition method in case 1 above, and the Y first indication information acquisition methods of the Y first uplink information and the first indication information acquisition method in case 2 above are similar, and a description thereof will not be provided.

For example, the first uplink channel is a PUCCH, a part of the first uplink information carried by the first uplink channel may be HARQ-ACK of a PDSCH scheduled by the network device through the first DCI, and the remaining part of the first uplink information may be HARQ-ACK or SR or CSI of an SPS PDSCH configured by the network device through the first higher layer parameter; for another example, a part of the first uplink information may be HARQ-ACK of the PDSCH scheduled by the network device through the first DCI, and the remaining part of the first uplink information may be data carried by the network device through Type-1CG PUSCH configured by the first higher layer parameter.

302: the terminal equipment acquires M pieces of second indication information, wherein the M pieces of second indication information correspond to M pieces of second uplink information, and the M pieces of second uplink information are borne on a second uplink channel.

The priority of the first uplink channel is different from that of the second uplink channel, that is, one of the first uplink channel and the second uplink channel is a high-priority uplink channel, and the other is a low-priority uplink channel. In addition, the first uplink channel and the second uplink channel are overlapped in time domain, that is, there is an overlapped portion between the time domain resource corresponding to the first uplink channel and the time domain resource corresponding to the second uplink channel, and the overlapped time domain resource is the first time domain resource.

Illustratively, the second uplink channel includes a second PUCCH or a second PUSCH. Each of the N pieces of second uplink information may be second UCI or data. Wherein the second UCI includes at least one of: HARQ-ACK, P-CSI, SP-CSI, A-CSI, SR, and BFR.

The scheduling manner of the M second uplink messages is similar to the scheduling manner of the N first uplink messages, and is not described again. When the second indication information is indicated by a field in a second DCI, the second indication information is used to indicate whether uplink information scheduled by the second DCI can be multiplexed with uplink information of different priorities, and when the second indication information is indicated by a field in a second higher-level parameter, the second indication information is used to indicate whether uplink information carried by an uplink channel configured by the second higher-level parameter can be multiplexed with uplink information of different priorities. The manner of obtaining the M second indication information is not described in detail, which is similar to the manner of obtaining the N first indication information.

Optionally, the priority of the first uplink channel is the priority of the N first uplink messages, and the N first uplink messages have the same priority.

Optionally, the priority of the uplink channel refers to a physical layer priority, and is used to implicitly indicate a service type corresponding to uplink information carried by the uplink channel or a delay or reliability requirement of the service.

Alternatively, step 302 may not be performed. For example, in example 1 below, when the first uplink channel priority is higher than the second uplink channel priority, the terminal device determines whether to multiplex the N first uplink information with the M second uplink information according to only the N first indication information, and at this time, the terminal device does not need to acquire the M second indication information. That is, in some methods, the terminal device only needs to acquire the indication information (the first indication information or the second indication information) corresponding to the uplink information with the high priority, and does not need to acquire the indication information corresponding to the uplink information with the low priority.

Optionally, the obtaining N pieces of first indication information includes: receiving the N pieces of first indication information from the network equipment.

Optionally, the obtaining M pieces of second indication information includes: receiving the M pieces of second indication information from the network device.

Optionally, in an embodiment, the terminal device may receive DCI or higher layer parameters including the M pieces of second indication information, but does not acquire the M pieces of second indication information from the DCI or higher layer parameters, or does not use the M pieces of second indication information.

303: and the terminal equipment determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the N pieces of first indication information and/or the M pieces of second indication information.

Each piece of first indication information is used for indicating whether corresponding first uplink information and uplink information with different priorities are subjected to multiplexing transmission; each second indication information is used for indicating whether the corresponding second uplink information and the uplink information with different priorities are subjected to multiplexing transmission. Therefore, the terminal device may determine whether to multiplex the N first uplink information with the M second uplink information according to the N first indication information and/or the M second indication information.

When it is determined that the N first uplink information and the M second uplink information are multiplexed and transmitted, the terminal device may multiplex and transmit the N first uplink information and the M second uplink information, for example, may multiplex and transmit the N first uplink information and the M second uplink information on a third uplink channel for joint transmission; when it is determined that the N first uplink information and the M second uplink information cannot be multiplexed for transmission, the terminal device may send, to the network device, the uplink information carried by the high-priority uplink channel at the first time domain resource location, and abandon sending, to the network device, the uplink information carried by the low-priority uplink channel at the first time domain resource location. In addition, when it is determined that the N first uplink information and the M second uplink information cannot be multiplexed and transmitted subsequently, the transmission of the uplink information carried by the uplink channel with low priority may be abandoned at the first time domain resource location, and only the uplink information carried by the uplink channel with high priority may be transmitted, which is not described repeatedly.

Examples 1 to 4 below provide several ways how to determine whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to embodiments of the present application. It is to be understood that the following examples are not intended to limit the present application in any way.

Example 1: and the terminal equipment determines whether to carry out multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information according to the indication information corresponding to the uplink channel with the high priority.

Optionally, the terminal device determines the priority of the first uplink channel and the priority of the second uplink channel.

It should be noted that, in this scheme, even if the terminal device receives the indication information corresponding to the uplink channel with the low priority, it is determined whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to the indication information corresponding to the uplink channel with the high priority.

Based on the above, each piece of uplink information corresponds to a priority indicator (priority indicator) field. Therefore, the terminal device may determine a priority of each first uplink information according to a priority indicator (priority indicator) field corresponding to each first uplink information, and use the priority of one or more first uplink information in the N first uplink information as the priority of the first uplink channel. Likewise, the terminal device may use the priority of one or more second uplink information in the M second uplink information as the priority of the second uplink channel.

In this application, the priority of the first uplink channel is higher than the priority of the second uplink channel. The case where the priority of the second uplink channel is higher than that of the first uplink channel is similar to the case where the priority of the first uplink channel is higher than that of the second uplink channel, and description thereof is not repeated.

It is understood that the following 1.1-1.3 are descriptions of different embodiments listed in example 1 according to different upstream information sources. In addition, it should be noted that, the "determining (or not) to perform multiplexing transmission" described in this application may mean "determining (or not) to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information" or "determining (or not) to perform multiplexing transmission on the first uplink information and the second uplink information" or "determining (or not) to perform multiplexing transmission on the uplink information" and the like, and is not described again.

1.1, aiming at the condition that the N pieces of first uplink information are scheduled through N pieces of first DCI.

The scheduling of the N first uplink information through the N first DCIs may include the following several manners. It should be understood that the following scheduling schemes are not intended to limit the present application.

Optionally, the first uplink channel is a first PUCCH for carrying HARQ-ACK, where the first PUCCH carries HARQ-ACK information corresponding to N first PDSCHs, the N first PDSCHs are scheduled by the N first DCIs, each first DCI includes one piece of first indication information, and each piece of first indication information is used to indicate whether HARQ-ACK of the first PDSCH scheduled by the first DCI corresponding to the first indication information may be multiplexed with uplink information of different priorities.

Optionally, the first uplink channel is a first PUCCH carrying HARQ-ACK and a-CSI, where the first PUCCH carries HARQ-ACK information and N2 a-CSI information corresponding to N1 first PDSCHs, the N1 first PDSCHs are scheduled by N1 first DCIs, the N2 a-CSI are scheduled by N2 first DCIs, each first DCI includes 1 first indication information for indicating whether HARQ-ACK and/or a-CSI of the first PDSCH scheduled by the first DCI may be multiplexed with uplink information of different priorities, where N1 is less than or equal to N, N2 is less than or equal to N, and N = N1+ N2. In addition, the N2 first DCIs may be different DCIs from the N1 first DCIs, or the same DCI, which is not limited in this application.

Optionally, the first uplink channel is a first GB PUSCH carrying data and/or a-CSI, and is scheduled by a first DCI (i.e., N = 1), where the first DCI includes a piece of first indication information, and the first indication information is used to indicate whether data and/or a-CSI carried by the first GB PUSCH scheduled by the first DCI may be multiplexed with uplink information of different priorities.

Optionally, the first uplink channel is a first GB PUSCH carrying data and HARQ-ACK, where the data is scheduled by N1 first DCIs, the HARQ-ACK has N2 (N2 = N-N1) first DCI schedules, each first DCI includes one piece of first indication information, and each piece of first indication information is used for whether data or HARQ-ACK of the first DCI schedule corresponding to the first indication information may be multiplexed with uplink information of different priorities.

For example, when the priority of the first uplink channel is higher than that of the second uplink channel, and the N first uplink messages are scheduled by the N first DCI, the terminal device may determine whether to multiplex the N first uplink messages with the M second uplink messages according to some or all of the N first indication messages.

The following 1.1.1-1.1.2 are exemplary descriptions of how to determine whether to perform multiplexing transmission according to the first indication information in the embodiment of 1.1.

1.1.1, determining whether to carry out multiplexing transmission according to first indication information included in first DCI received by the terminal equipment last.

For example, when the priority of the first uplink channel is higher than that of the second uplink channel, and the N first uplink messages are scheduled by the N first DCI, the terminal device may determine whether to multiplex the N first uplink messages with the M second uplink messages according to the first indication information included in the third downlink control information. The third downlink control information is the first DCI received by the terminal device last in the N first DCIs.

When the network device schedules the N first uplink information through the N first DCIs, the N first DCIs may be sent to the terminal device at a plurality of time domain positions configured in advance, and the terminal device may blindly detect the N first DCIs sent by the network device at the plurality of time domain positions. Therefore, the last received first DCI is the first DCI that the terminal device finally blindly detects. The blind detection of the DCI means that the terminal device needs to attempt DCI reception for a plurality of candidate positions (e.g., frequency domain positions) of each reception time domain position, and assumes different DCI formats (corresponding to different load sizes) to perform decoding and Cyclic Redundancy Check (CRC), and when a certain candidate position and a certain DCI format are combined, the blind detection is considered to be successful through the CRC, that is, one piece of DCI is blind detected.

It should be noted that the network device may transmit multiple DCIs at one time domain location. Accordingly, the terminal device may finally blind detect the plurality of first DCIs. Optionally, in this case, the terminal device may use a target first DCI in the multiple first DCIs that are finally blindly detected as the last first DCI, and when the first indication information included in the target first DCI indicates that multiplexing transmission may be performed with uplink information of different priorities, the terminal device determines to perform multiplexing transmission on the N first uplink information and the M second uplink information. For example, the target first DCI may be a first DCI with a largest carrier number among a plurality of first DCIs last detected by the terminal device in a blind manner. Optionally, in this case, the terminal device may regard all the first DCIs that are finally detected in a blind manner as third DCIs, and only when all the first indication information included in the first DCIs indicate that multiplexing transmission may be performed with uplink information of different priorities, the terminal device determines to perform multiplexing transmission on the N first uplink information and the M second uplink information.

In addition, the interpretation of the DCI received last by the terminal device involved in the following is similar to that described above, and the description is not repeated.

For example, when a value of first indication information included in the third downlink control information is a first preset value, it is determined to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information, for example, when the indication information is carried by adding a field in DCI, when the value of the field is 1, that is, the value of the first indication information is 1, it is determined to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information; when the value of the first indication information included in the third downlink control information is not a first preset value, it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed, for example, when the value of the first indication information is 0, it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed.

It should be noted that, in practical application, it may also be determined whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to first indication information included in any one of the N first DCIs, which is not limited in this application.

It can be seen that the terminal device only needs to determine whether to multiplex the N first uplink information and the M second uplink information according to the last received first DCI, and does not need to pay attention to other first DCI. In this way, the network device may only concern the last first DCI in the process of indicating whether to multiplex the N first uplink information and the M second uplink information, and the indication mode is flexible; in addition, from the time domain, the time domain position of the first DCI received last by the terminal device is also generally the one DCI closest to the starting position of the first uplink channel, and it is more accurate to determine whether the multiplexing transmission of the N first uplink information and the M second uplink information is possible by using the indication result in the first DCI; moreover, the network device indicates through the first DCI, and can also adjust and correct the first DCI with the indication error, so that the fault tolerance rate in the indication process of the network device is improved.

1.1.2, determining whether to carry out multiplexing transmission according to the N pieces of first indication information.

Exemplarily, when the values of the N first indication information are completely the same, it is determined that the N first uplink information and the M second uplink information are multiplexed; and when the values of the N pieces of first indication information are not completely the same, determining that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

Further, when the values of the N pieces of first indication information are completely the same and all values are first preset values, determining that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission; and when the value of at least one piece of indication information in the N pieces of first indication information is not the first preset value, determining that multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information is not allowed. For example, when all the values of the N pieces of first indication information are 1, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed.

It can be seen that, by determining whether to multiplex the N first uplink information and the M second uplink information by using the N first DCIs including all the first indication information, the accuracy of the determination result can be ensured. In addition, in practical applications, although the network device sends the first DCI at the last time domain position, it cannot guarantee that the terminal device can successfully detect the first DCI in a blind manner, and there may be a problem that the first indication information included in the last first DCI is lost. The terminal equipment determines whether to multiplex the N pieces of first uplink information and the M pieces of second uplink information according to the values of the first indication information included in all the received first DCI, and can still accurately determine whether to multiplex the N pieces of first uplink information and the M pieces of second uplink information even if the last first DCI is lost.

Optionally, the terminal device does not expect that the values of the first indication information included in the N first DCIs are different, at this time, the terminal device determines whether to multiplex the N first uplink information with the M second uplink information according to the N first indication information, which is equivalent to determining whether to multiplex the N first uplink information with the M second uplink information according to the value of any one of the N first indication information, and as long as the value of the one first indication information is the first preset value, it may determine to multiplex the N first uplink information with the M second uplink information.

In practical application, whether multiplexing transmission is performed may also be determined by considering whether all of the values of some of the N first DCI indication information are the same or a first preset value, for example, whether the last two first indication information of the N first indication information are both the first preset value or the same may be considered, and if the last two first indication information are both the first preset value, it is determined that multiplexing transmission of uplink information is possible. The number and position of the first indication information are not limited in the present application.

1.2, aiming at the condition that the N pieces of first uplink information are configured through N pieces of first higher-layer parameters.

The N first uplink information may be configured through N first higher layer parameters in the following configuration manners. It should be understood that the following configurations are not intended to limit the present application.

Optionally, the first uplink channel is a first PUCCH for carrying HARQ-ACK or SR corresponding to the SPS PDSCH, and the first PUCCH carries HARQ-ACK information corresponding to the N SPS PDSCHs, or 1 SR; or the first PUCCH carries HARQ-ACK and N2 (N2 = N-N1) SRs corresponding to N1 SPS PDSCH, the first higher layer parameter of each SPS PDSCH or the first higher layer parameter of each SR or the PUCCH resource configuration parameter of the SR includes a first indication information, and the first indication information is used for whether the HARQ-ACK or SR corresponding to the SPS PDSCH configured by the higher layer parameter can be multiplexed with uplink information of different priorities.

Optionally, the first uplink channel is a first CG PUSCH for carrying data, and the first uplink channel corresponds to a CG PUSCH higher-layer configuration parameter (first higher-layer parameter), that is, N =1. And the higher layer configuration parameter comprises a first indication information, and the first indication information is used for indicating whether data carried by a CG PUSCH configured by the higher layer parameter can be multiplexed and transmitted with uplink information with different priorities.

Optionally, the first uplink channel is a first CG PUSCH for carrying data and HARQ-ACK corresponding to the SPS PDSCH, the data carried by the first uplink channel corresponds to one CG PUSCH high-level configuration parameter (first high-level parameter), the HARQ-ACK carried by the first uplink channel corresponds to N1 (N1 = N-1) SPS PDSCH high-level configuration parameters (first high-level parameters), each first high-level parameter includes a first indication information, and the first indication information is used for indicating whether the data carried by the CG PUSCH configured by the first high-level channel or the HARQ-ACK corresponding to the SPS PDSCH can be multiplexed with uplink information of different priorities or not.

The terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to the N first indication information included in the N first higher layer parameters.

Illustratively, when values of N pieces of first indication information are completely the same or the values are completely the same and are all a first preset value, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission; otherwise, it is determined that the multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information is not allowed.

It can be seen that only when the values of the N first indication information included in the N first high-level parameters are all the first preset values, the terminal device performs multiplexing transmission on the N first uplink information and the M second uplink information, so that the process of performing multiplexing transmission on the N first uplink information and the M second uplink information is more accurate.

Optionally, the terminal device does not expect that the values of the first indication information included in the N first higher layer parameters are different, at this time, the terminal device determines whether to multiplex the N first uplink information with the M second uplink information according to the N first indication information, which is equivalent to determining whether to multiplex the N first uplink information with the M second uplink information according to any one of the N first indication information, and if the value of the first indication information is a first preset value, it determines to multiplex the N first uplink information with the M second uplink information.

1.3, aiming at the N pieces of first uplink information, the first DCI scheduling and the first high-layer parameter configuration are available.

The N pieces of first uplink information are scheduled by the first DCI, and the case where the first high-layer parameter configuration exists may include the following several manners. It should be understood that the following several ways are not limiting to the present application.

Optionally, the X first uplink information are HARQ-ACKs of the first PDSCH scheduled through X first DCI, and the remaining Y first uplink information are HARQ-ACKs of Y SPS PDSCHs configured through Y first higher layer parameters.

Optionally, the X first uplink information is data carried by a GB PUSCH scheduled by one first DCI (i.e., X = 1), and the remaining Y first uplink information are HARQ-ACKs of Y SPS PDSCHs configured by Y first higher layer parameters.

Illustratively, if X first uplink messages of the N first uplink messages are scheduled by X first downlink control messages, the remaining Y first uplink messages are configured by Y first higher layer parameters. The terminal device may preferentially determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to the first indication information included in the first DCI. Therefore, the terminal device may determine whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information according to some or all of the X pieces of first indication information included in the X pieces of first uplink information, respectively.

The terminal device determines, according to some or all of the X pieces of first indication information, whether to implement multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information, which may be referred to as implementation manners in 1.1.1 and 1.1.2, and description is not repeated.

In addition, the terminal device may further determine whether to perform multiplexing transmission on the N pieces of first uplink information and the M pieces of second uplink information according to X pieces of first indication information included in the X pieces of first downlink control information, respectively, and Y pieces of first indication information included in the Y pieces of first higher-layer parameters, respectively. For example, when values of X first indication information included in the X first downlink control information and Y first indication information included in the Y first high-level parameters are the same (or the values are the same and are the first preset values), it is determined that multiplexing transmission is performed on the N first uplink information and the M second uplink information, otherwise, multiplexing transmission is not performed on the N first uplink information and the M second uplink information.

In the above, X and Y are both positive integers greater than or equal to 1, and N = X + Y.

Optionally, the terminal device does not expect that the values of the N first indication information are different, at this time, the terminal device determines whether to multiplex the N first uplink information and the M second uplink information according to the N first indication information, which is equivalent to determining whether to multiplex the N first uplink information and the M second uplink information according to any one of the N first indication information, and if the value of the one first indication information is a first preset value, it may determine to multiplex the N first uplink information and the M second uplink information.

It can be seen that, the first indication information included in the first DCI and the first indication information included in the first higher layer parameter are considered, so that the accuracy of the determination result is improved, and the transmission efficiency is further improved.

Optionally, in an embodiment of the present application, although in example 1, the N first uplink information are scheduled by N first DCI, N first higher layer parameter configurations, or a part of the N first uplink information is scheduled by the first DCI, and the rest is configured by the first higher layer parameter. However, the types of uplink information scheduled by different first DCI or the types of uplink information configured by different first higher layer parameters may not be the same. Therefore, the N types of first uplink information may be classified into P classes, each class including one or more first uplink information. The terminal device may determine the first uplink information of the first type according to a preset priority between the P types of first uplink information, and determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to a first DCI corresponding to the first uplink information of the first type or first indication information included in a first high-level parameter. The preset priority may be a priority among a plurality of uplink information types configured in advance by the network device. For example, data > UCI, or HARQ-ACK > CSI/SR, or A-CSI > SPS PDSCH HRAQ-ACK/SR. The priority level of the network device is configured in advance, and the description is not repeated. In this application, the priority preset according to the type of the uplink information may be referred to as a type priority.

For example, the first type of first uplink information may be the first uplink information with the highest priority among the P types of first uplink information, or the first uplink information with the lowest priority, which is not limited in this application.

It should be noted that this embodiment mode can be combined differently from the case of example 1, and for example, there are the following combination modes. The combination is a combination of this embodiment mode and example 1 in the execution order.

Optionally, in an implementation manner, according to the method described in example 1, the terminal device determines N1 pieces of first indication information from the N pieces of first indication information, and uses the N1 pieces of first indication information to determine whether multiplexing transmission is possible; determining N2 first uplink information of the first type from N1 first uplink information corresponding to the N1 first indication information according to the type priority; subsequently, it is determined whether N pieces of first uplink information and M pieces of second uplink information can be multiplexed according to the first indication information corresponding to the N2 pieces of first type uplink information, and the determination method is similar to that in example 1. Wherein N2 is less than or equal to N1, and N1 is less than or equal to N.

For example, referring to example 1.1.1, a terminal device first determines that first indication information included in a first DCI received last and corresponding to an uplink channel with a high priority is used to determine whether to perform multiplexing transmission; when the first DCI corresponds to a plurality of first uplink information, determining first uplink information of a first type in the plurality of first uplink information according to the type priority of the plurality of first uplink information; and the terminal equipment determines whether multiplexing transmission is carried out or not according to the determined first indication information corresponding to the first uplink information of the first type.

For example, referring to example 1.1.2, the terminal device determines that N pieces of first indication information included in N pieces of first DCI corresponding to the uplink channel with the high priority are used for determining to perform multiplexing transmission; further, according to the type priority, determining N1 first type uplink information from the N first uplink information; and then, the terminal equipment determines whether multiplexing transmission is carried out or not according to the determined N1 first indication information corresponding to the N1 first uplink information of the first type. For example, when all the N1 first indication information values are the first preset value, it is determined that multiplexing transmission is possible, otherwise, it is determined that multiplexing transmission is not possible.

For example, referring to example 1.2, the terminal device determines that N pieces of first indication information configured by N pieces of first higher-layer parameters corresponding to the high-priority uplink channel are used for determining to perform multiplexing transmission; further, according to the type priority, determining N1 first type uplink information from the N first uplink information; and then, the terminal equipment determines whether multiplexing transmission is carried out or not according to the determined N1 first indication information corresponding to the N1 first uplink information of the first type. For example, when all the N1 first indication information values are the first preset value, it is determined that multiplexing transmission is possible, otherwise, it is determined that multiplexing transmission is not possible.

For example, referring to example 1.3, consider a case where X first uplink information among N first uplink information on an uplink channel of high priority is scheduled by DCI, and Y first uplink information is configured by a higher layer parameter, where N = X + Y. The terminal device may determine that X first indication information included in X first DCI corresponding to the high-priority uplink channel is used for determining to perform multiplexing transmission; further, according to the type priority, determining N1 first type uplink information from the X first uplink information; and then, the terminal equipment determines whether multiplexing transmission is carried out or not according to the determined N1 first indication information corresponding to the N1 first uplink information of the first type. For example, when all the N1 first indication information values are the first preset value, it is determined that multiplexing transmission is possible, otherwise, it is determined that multiplexing transmission is not possible.

Optionally, in an embodiment of the present application, the terminal device determines, according to the type priority, N2 pieces of first uplink information that are of a first type in the N pieces of first uplink information, where N2 is less than or equal to N; furthermore, the terminal device may perform the determination of the multiplexing transmission using part or all of the first indication information in N2 in a manner similar to that in example 1, for example, as shown in similar 1.1.1, the terminal device may perform the determination of the multiplexing transmission according to the first indication information in the first DCI received last by the N2 first indication information, or, as shown in similar 1.1.2, the terminal device may determine whether to perform the multiplexing transmission according to N2 first indication information corresponding to the N2 first type uplink information.

Example 2: the priorities of the first uplink channel and the second uplink channel are not distinguished, but whether the N pieces of first uplink information and the M pieces of second uplink information are subjected to multiplexing transmission is preferentially determined according to the indication information included in the DCI.

It is understood that the following 2.1-2.3 are descriptions of different embodiments listed in example 2 according to different sources of upstream information.

2.1, aiming at the condition that part or all of the uplink information carried by one uplink channel is DCI scheduling and all of the uplink information carried by the other uplink channel is configured by high-layer parameters.

The following modes may be included when part or all of the uplink information carried by one uplink channel is scheduled by DCI, and all of the uplink information carried by another uplink channel is configured by a higher-layer parameter. It should be understood that, in the following several manners, the following description is given by taking an example that part or all of the uplink information carried by the first uplink channel is DCI scheduled, and all of the uplink information carried by the second uplink channel is configured by a higher-layer parameter, and the present application is not limited thereto.

Optionally, the N first uplink information are HARQ-ACKs of N first PDSCHs scheduled by N first DCIs, and the M second uplink information are HARQ-ACKs and/or M =1 SRs corresponding to M SPS PDSCHs configured by M second higher layer parameters.

Optionally, the N first uplink information are HARQ-ACKs of N first PDSCHs scheduled by N first DCIs, and the M second uplink information are data carried by a CG PUSCH configured by one second higher layer parameter (i.e., M = 1).

When all the uplink information carried by the second uplink channel is configured by the higher layer parameter, and when part or all of the N first uplink information carried by the first uplink channel is scheduled by the first DCI, the terminal device determines whether to implement the implementation manner of multiplexing transmission between the N first uplink information and the M second uplink information, which may be determined according to the first indication information included in the first DCI of the scheduled first uplink information, specifically, refer to 1.1, which determines whether to implement the description of multiplexing transmission according to the first indication information, and is not described again.

When all the uplink information carried by the first uplink channel is configured by the higher layer parameter and part or all of the N second uplink information carried by the second uplink channel is scheduled by the second DCI, an implementation manner of determining whether to perform multiplexing transmission on the N first uplink information and the M second uplink information is as follows:

for example, Z second uplink messages in the M second uplink messages are scheduled by Z second DCIs, where each second DCI includes one second indication message; the terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to some or all of the Z second indication information included in the Z second DCI, where Z is less than or equal to M.

The terminal device determines, according to part or all of the Z pieces of second indication information, whether to implement multiplexing transmission of the N pieces of first uplink information and the M pieces of second uplink information, which may refer to the implementation manners in 1.1.1 and 1.1.2 and will not be described repeatedly.

It can be seen that, because the manner of the uplink information configured by the first higher-layer parameter is relatively fixed, and the manner of scheduling the uplink information by the second DCI is relatively flexible, at this time, although the priority of the first uplink channel is higher than that of the second uplink channel, it is still determined whether to multiplex the N first uplink information and the M second uplink information according to the N first indication information, which may cause an inaccurate determination result. At this time, whether the N pieces of first uplink information and the M pieces of second uplink information are multiplexed is determined according to the second indication information, so that the accuracy can be improved.

2.2, the uplink information scheduled by the DCI exists for the uplink information carried by the two uplink channels.

Wherein, the uplink information carried by the two uplink channels has the condition of the uplink information scheduled by the DCI. It should be understood that the following aspects are not intended to limit the present application.

Optionally, the L first uplink information is HARQ-ACKs of L first PDSCHs scheduled by L first DCIs, and the R second uplink information is HARQ-ACKs of R second PDSCHs scheduled by R second DCIs.

Optionally, the L first uplink information are HARQ-ACKs of L first PDSCHs scheduled by L first DCIs, and the R second uplink information are data and/or a-CSI carried by a GB PUSCH scheduled by one second DCI (R = 1).

Optionally, the L first uplink information is data and/or a-CSI carried by a GB PUSCH scheduled by one first DCI (L = 1), and the R second uplink information is HARQ-ACK of R second PDSCHs scheduled by R second DCIs.

Illustratively, when L first uplink information of the N first uplink information is scheduled by L first downlink control information, and R second uplink information of the M second uplink information is scheduled by R second downlink control information, where L and R are both integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M, the terminal device may determine whether to multiplex the N first uplink information with the M second uplink information according to part or all of the L first downlink control information and the R second downlink control information.

For example, the terminal device may determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to third indication information included in the fifth downlink control information; the fifth downlink control information is downlink control information that is received last by the terminal device in the L first downlink control information and the R second downlink control information, and when the fifth downlink control information is downlink control information that is received last in the L first downlink control information, the third indication information is first indication information, or when the fifth downlink control information is downlink control information that is received last in the R second downlink control information, the third indication information is second indication information.

For example, the terminal device may determine whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to the L pieces of first indication information and the R pieces of second indication information. For example, when values of L first indication information included in the L first downlink control information and values of R second indication information included in the R first downlink control information are the same (or the values are the same and are both a first preset value), the terminal device determines to perform multiplexing transmission on the N first uplink information and the M second uplink information; otherwise, the terminal device determines that the multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

Illustratively, the terminal device does not expect that values of the L pieces of first indication information and the R pieces of second indication information are different, and determines whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to the L pieces of first indication information and the R pieces of second indication information, which is equivalent to determining whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to any one of the L pieces of first indication information and the R pieces of second indication information, and determines to multiplex the N pieces of first uplink information with the M pieces of second uplink information as long as a value of the one piece of first indication information is a first preset value.

And 2.3, aiming at the condition that all the uplink information carried by the two uplink channels is configured by the higher layer parameters.

Illustratively, when the N first uplink messages are configured by N first uplink parameters, and the M second uplink messages are configured by M second uplink parameters, each first uplink parameter includes a first indication message, and each second uplink parameter includes a second indication message. The terminal device may determine, according to the N first indication information and the M second indication information, whether to perform multiplexing transmission on the N first uplink information and the M second uplink information, for example, when values of the N first indication information and the M second indication information are the same (or the values are the same and are both first preset values), the terminal device determines to perform multiplexing transmission on the N first uplink information and the M second uplink information; otherwise, the terminal device determines that the multiplexing transmission of the N first uplink information and the M second uplink information cannot be performed.

In another embodiment of the present application, since both the N first uplink messages and the M second uplink messages may include multiple message types. At this time, the terminal device may determine the first type of uplink information according to the type priority of the uplink information preconfigured by the network device; then, according to the DCI corresponding to the first type of uplink information or the indication information included in the higher layer parameter, for example, preferentially according to the indication information included in the DCI, it is determined whether to perform multiplexing transmission.

This embodiment mode can be combined differently from the case of example 2, for example, there are the following combination modes. The combination is a combination of this embodiment mode and example 2 in the execution order.

Optionally, in an implementation manner, the terminal device may determine, according to example 2, whether multiplexing transmission may be performed according to the L2 pieces of first indication information and/or the R2 pieces of second indication information, where L2 is greater than or equal to zero, R2 is greater than or equal to zero, and L2 and R2 cannot be zero at the same time; and determining one or more first types of uplink information from the L2 pieces of first uplink information corresponding to the L2 pieces of first indication information and/or the R2 pieces of second uplink information corresponding to the R2 pieces of second indication information according to the type priority, and determining whether multiplexing transmission can be performed according to the indication information corresponding to the one or more first types of uplink information.

For example, referring to example 2.1, taking an example that all uplink information carried by a first uplink channel is configured by a higher layer parameter and Z second uplink information in M second uplink information carried by a second uplink channel is scheduled by Z second DCIs, L2=0 and R2>0 are determined, where R2 second indication information is second indication information included in the Z second DCIs. Then, the terminal device determines R3 pieces of first-type second uplink information from the R2 pieces of second uplink information corresponding to the second indication information, and determines that the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed and transmitted when all values of the second indication information corresponding to the R3 pieces of first-type second uplink information are the first preset values.

For another example, referring to example 2.2, it is determined that L2= L and R2= R are obtained, where L2 pieces of first indication information are first indication information included in the L pieces of first DCI, and R2 pieces of second indication information are second indication information included in the R pieces of second DCI. Then, the terminal device determines L3 first uplink information of the first type and R3 second uplink information of the first type from first uplink information corresponding to L2 first indication information and second uplink information corresponding to R2 second indication information, and determines that multiplexing transmission can be performed on the N first uplink information and the M second uplink information when values of the first indication information corresponding to the L3 first uplink information of the first type are all first preset values and values of the second indication information corresponding to the R3 second uplink information of the first type are all first preset values.

Optionally, in another embodiment, the terminal device determines, according to the type priority, N4 first uplink information of the first type and/or M4 second uplink information of the first type from the N first uplink information and the M second uplink information, where N4 is greater than or equal to zero, M4 is greater than or equal to zero, and N4 and M4 are not zero at the same time; then, the terminal device determines whether multiplexing transmission can be performed according to the N4 first uplink information of the first type and/or the M4 second uplink information of the first type.

Optionally, when the M pieces of second uplink information do not include the first type of uplink information, the terminal device determines whether multiplexing transmission is possible according to the N4 pieces of first indication information corresponding to the N4 pieces of first uplink information of the first type, where the determination method is similar to the determination method in example 1; and/or

When the N first uplink information items do not include the first type of uplink information item, the terminal device determines whether multiplexing transmission is possible according to the M4 second indication information items corresponding to the M4 second type of second uplink information items, where a determination method is similar to that in example 1; and/or

Optionally, when the N first uplink messages include N4 first type uplink messages and the M second uplink messages include M4 first type uplink messages, the terminal device determines whether multiplexing transmission is possible according to the N4 first indication messages corresponding to the N4 first type uplink messages and the M4 second indication messages corresponding to the M4 second type uplink messages, where the determination method is similar to the determination method in example 2. For example, referring to example 2.2, when N3 pieces of first uplink information include uplink information scheduled by L4 pieces of first DCI and M4 pieces of second uplink information include uplink information scheduled by R4 pieces of second DCI, the terminal device determines whether multiplexing transmission is possible according to indication information (first indication information or second indication information) included in a DCI received last in the L4 pieces of first DCI scheduling and the R4 pieces of second DCI, and when a value of the indication information in the DCI received last is a first preset value, determines that multiplexing transmission is possible, otherwise, determines that multiplexing transmission is not possible.

Example 3: and preferentially determining whether multiplexing transmission can be carried out according to the first indication information or the second indication information according to the scheduling modes of the first uplink channel and the second uplink channel, and when the uplink information carried by both the first uplink channel and the second uplink channel is DCI scheduling or is configured by high-layer parameters, further determining whether multiplexing transmission can be carried out according to the first indication information or the second indication information according to the priority.

It is understood that the following 3.1-3.3 are descriptions of different embodiments listed in example 3 according to different upstream information sources.

3.1, aiming at the condition that part or all of the first uplink information carried by the first uplink channel and part or all of the second uplink information carried by the second uplink channel are both DCI scheduling.

The terminal equipment firstly determines the priority of a first uplink channel and a second uplink channel and determines that the first uplink channel is a high-priority uplink channel; therefore, the terminal device determines whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to part or all of the first indication information indicated by the DCI in the N first indication information corresponding to the first uplink channel, and specific implementation manners of whether to perform multiplexing transmission may refer to 1.1.1 and 1.1.2, which is not described repeatedly.

3.2, aiming at the condition that the N pieces of first uplink information carried by the first uplink channel and the M pieces of second uplink information carried by the second uplink channel are configured by high-layer parameters.

The terminal equipment firstly determines the priority of a first uplink channel and a second uplink channel and determines that the first uplink channel is a high-priority uplink channel; therefore, the terminal device determines whether to multiplex the N pieces of first uplink information and the M pieces of second uplink information according to part or all of the N pieces of first indication information corresponding to the first uplink channel, and a specific implementation manner of whether to multiplex transmission is shown in fig. 1.2, which is not described repeatedly.

3.3, aiming at the condition that part or all of the N first uplink information carried by the first uplink channel is DCI scheduled, and M second uplink information carried by the second uplink channel is configured by high-level parameters.

The terminal device may directly determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to some or all of the first indication information indicated by the DCI in the N first indication information corresponding to the first uplink channel, and specific implementation manners of whether to perform multiplexing transmission may refer to 1.1.1 and 1.1.2, which is not described repeatedly.

And 3.4, aiming at the N pieces of first uplink information carried by the first uplink channel, the N pieces of first uplink information are configured by high-layer parameters, and part or all of the M pieces of second uplink information carried by the second uplink channel is the condition of DCI scheduling.

The terminal device may directly determine whether to perform multiplexing transmission on the N first uplink information and the M second uplink information according to some or all of the first indication information indicated by the DCI in the M second indication information corresponding to the second uplink channel, and specifically, an implementation manner of whether to perform multiplexing transmission may refer to 2.1, and description is not repeated.

Example 4: and judging whether multiplexing transmission can be carried out according to the N pieces of first indication information and the M pieces of second indication information, and when the values of the N pieces of first indication information and the M pieces of second indication information are the same (or the values are the same and are both first preset values), determining that multiplexing transmission can be carried out on the N pieces of first uplink information and the M pieces of second uplink information. When the values of the N first indication information and the M second indication information are different (or at least 1 value is not the first preset value), it is determined that multiplexing transmission of the N first uplink information and the M second uplink information is not possible.

It should be further noted that before the terminal device determines whether to perform multiplexing transmission on the N first uplink information and the M second uplink information, it is also determined whether a timing requirement (time) is satisfied between the first uplink channel and the second uplink channel. The requirement of satisfying the multiplexing timing refers to whether the terminal device has enough time to multiplex the N first uplink information and the M second uplink information onto one channel for joint transmission before starting to transmit the uplink channel with the earliest starting time of the first uplink channel and the second uplink channel. And this step may occur before or after determining whether to multiplex the N first uplink messages and the M second uplink messages, which is not limited in this application.

Specifically, as shown in fig. 4, in a case where the first uplink channel and the second uplink channel are both PUCCHs, for example, the first uplink channel and the second uplink channel are a physical uplink control channel #1 (PUCCH # 1) and a physical uplink control channel #2 (PUCCH # 2), respectively, and HARQ-ACK of PDSCH is carried by one of the PUCCH #1 and the PUCCH #2, it is determined whether a time interval between an earliest starting symbol and an ending symbol of the PDSCH in the two PUCCHs is greater than or equal to T or not ₁ And T is ₁ ＝N ₁ +d _1,1 And +1, if yes, determining that the time between the first uplink channel and the second uplink channel is satisfied, and if not, determining that the time between the first uplink channel and the second uplink channel is not satisfied. If the first uplink channel and the second uplink channel do not carry HARQ-ACK, for example, SR and CSI are carried by the first uplink channel and the second uplink channel, no timeline exists, in other words, it is default that the first uplink channel and the second uplink channel satisfy timeline.

Wherein N is ₁ To a predetermined value, related to subcarrier spacing and UE capability, d _1,1 Is a preset offset value, N, related to the time domain length and type of PDSCH ₁ +d _1,1 For ensuring that the UE has enough time to generate HARQ-ACK after receiving the PDSCH and complete the preparation for transmission, the extra 1 symbol is a processing delay specially introduced for multiplexing multiple PUCCHs.

For example, as shown in fig. 5, in a case where one of the first uplink channel and the second uplink channel is a PUCCH and the other is a PUSCH, for example, the PUCCH is used for carrying HARQ-ACK, it is determined whether a time interval between an earliest starting symbol in the PUCCH and the PUSCH and an ending symbol of the PDSCH is greater than or equal to T described above ₁ If yes, determining that the two uplink channels meet the time, and if not, determining that the two uplink channels do not meet the time; if the PUSCH carries GB PUSCH or Type-2 CG PUSCH, then determining whether the time interval between the earliest first starting symbol and the ending symbol of the downlink control channel PDCCH where the DCI is positioned is greater than or equal to T ₂ And T is ₂ ＝N ₂ +d _2,1 And +1, if yes, determining that the two uplink channels meet the time, and if not, determining that the two uplink channels do not meet the time.

Wherein N is ₂ Is a preset value, related to subcarrier spacing and UE capability, d _2,1 Is a preset offset value, N, related to the type of PUSCH ₂ +d _2,1 And the method is used for ensuring that the terminal equipment has enough time to complete the PUSCH transmission preparation after receiving the DCI, and the additionally introduced 1 symbol is the processing delay introduced to the multiplexing of the PUCCH and the PUSCH.

It can be seen that, in the embodiment of the present application, the terminal device determines whether multiplexing transmission can be performed on the N first uplink information and the M second uplink information according to the N first indication information corresponding to the N first uplink information and/or the M second indication information corresponding to the M second uplink information, instead of performing multiplexing transmission or giving up multiplexing transmission simply and directly, so that flexibility of the terminal device in performing multiplexing transmission or giving up multiplexing transmission is improved, which can not only avoid that multiplexing transmission affects delay and reliability of high priority service transmission, but also improve transmission efficiency of low priority service.
