[0023] In the following, in conjunction with the drawings, the uplink object transmission method, apparatus, communication device, system and storage medium according to the embodiments of the present application are described in detail through several embodiments and their application scenarios.
[0024] Currently, in the 3rd Generation Partnership Project (3GPP (registered trademark)) protocol, a terminal can transmit only one type of uplink channel or uplink signal in one time unit (e.g., a slot or a sub-slot), and defines criteria for multiplexing or discarding when multiple types of uplink channel / signal transmission times overlap. Here, the uplink channel may include a PUCCH, a PUSCH, a Physical Random Access Channel (PRACH), etc., the uplink signal may include a channel sounding reference signal (SRS), an uplink (UL) phase tracking reference signal (PTRS), a UL demodulation reference signal (DMRS), etc., and the PUCCH may be used to transmit various uplink control information (UCI), including a hybrid automatic repeat request-acknowledgement / negative acknowledgement (HARQ-ACK / NACK), an uplink scheduling request (SR), a channel state information (CSI) report, etc.
[0025] In Rel-15 / 16, uplink transmission parameters including information such as uplink transmission beam used for uplink channel / signal are determined by spatial relation information SpatialRelationInfo. In order to simplify beam indication, Rel-17 designs a unified Transmission Configuration Indicator (TCI) frame and introduces a UL TCI state similar to a DL TCI state, which is a downlink transmission parameter including information such as a downlink (DL) receiving beam, and both PUCCH / PUSCH can use the same UL TCI state, and thus, in a joint TCI indication situation, the UL TCI state and the DL TCI state can be simultaneously indicated by one joint TCI state. The scenario of multi-transmission / reception points / multi-antenna panels supported by Rel-16 allows a terminal to simultaneously receive the same or different data from multiple transmission / reception nodes (TRPs) to improve transmission reliability or throughput performance, and simultaneously supports two TRPs to independently schedule their PUSCHs and PUCCHs, but still cannot simultaneously transmit uplink channels / signals that overlap in time. Rel-17 further strengthens multi-transmission / reception points, and in the uplink, supports PUCCH / PUSCH reception / transmission using multiple beams using Time-Division Multiplexing (TDM) technology.
[0026] 3GPP has discussed the situation where a terminal has multiple transmit antenna panels, one of which is the capability to support simultaneous transmission of multiple antenna panels, but the protocols in the related art do not support multiple antenna panels transmitting signals simultaneously and multiple uplink channels / signals transmitting simultaneously.
[0027] In order to solve the above problem, in an embodiment of the present application, a terminal can determine N first uplink objects having overlapping transmission times from at least two uplink objects within one time unit indicated by a network side device, where N is an integer greater than 1, and the terminal can simultaneously transmit the N first uplink objects or transmit a second uplink object, where each first uplink object in the N first uplink objects belongs to a set of uplink objects among N sets of uplink objects corresponding to at least two uplink objects, respectively, the first uplink object is at least one of a PUSCH, a PUCCH, and an uplink RS, and the second uplink object is any one of a first target uplink object in the N first uplink objects and a second target uplink object other than the N first uplink objects among the at least two uplink objects. With this method, N first uplink objects or second uplink objects whose transmission times overlap are determined based on N sets of uplink objects corresponding to at least two uplink objects indicated by the network side equipment to the terminal, and the terminal can simultaneously transmit the N first uplink objects or transmit the N second uplink objects, so there is no need to directly discard or multiplex some uplink objects according to the discard and multiplexing criteria of the related technology, thereby improving the efficiency of the terminal transmitting uplink objects.
[0028] An embodiment of the present application provides an uplink object transmission method, and Fig. 2 shows a flowchart of the uplink object transmission method according to an embodiment of the present application. As shown in Fig. 2, the uplink object transmission method according to an embodiment of the present application may include the following steps 201 and 202.
[0029] In step 201, the terminal determines N first uplink objects having overlapping transmission times from at least two uplink objects within one time unit indicated by the network side equipment, where N is an integer greater than 1.
[0030] In an embodiment of the present application, each first uplink object among the N first uplink objects belongs to a set of uplink objects among the N sets of uplink objects corresponding to the at least two uplink objects, respectively.

[0037] Optionally, in the embodiment of the present application, the target reference signal may be a DMRS or a PTRS.
[0038] Optionally, in an embodiment of the present application, in the above (1.1.1), the preset threshold value may be pre-configured or pre-defined by the network side equipment, or may be agreed upon by a protocol, or may be autonomously determined by the terminal.
[0039] In an embodiment of the present application, when the N first uplink objects are N PUSCHs, each PUSCH may include any one of a single PUSCH, a one-time transmission in PUSCH repeated transmission, and a PUSCH transmission of one TB in PUSCH transmission of multiple transmission blocks TB scheduled at one time, and the N PUSCHs can satisfy at least one of a number of conditions, so that the terminal can determine the N first uplink objects in various scheduling situations.
[0040] Optionally, in the embodiment of the present application, when the first uplink object is the above (2), the above N first uplink objects are N PUCCHs, and the N PUCCHs are: (2.1) The above N PUCCH resources do not overlap in the frequency domain; (2.2) The N PUCCHs are PUCCHs simultaneously transmitted using N uplink transmission parameters or N antenna panels; (2.3) The above N PUCCHs may satisfy any one of the following: the first PUCCH is a PUCCH that is simultaneously transmitted in a Single Frequency Network (SFN) manner using N uplink transmission parameters or N antenna panels.
[0041] In the embodiment of the present application, in the above (2.1), the resources of the N PUCCHs do not overlap in the frequency domain in order to ensure that the REs occupied by the DMRSs of the N PUCCHs do not overlap with the data REs.
[0042] Optionally, in the embodiment of the present application, in the above (2.2), the uplink transmission parameter may be at least one of an uplink TCI state, an uplink transmission beam, a spatial relation, and a power control parameter.

[0044] Alternatively, in the embodiment of the present application, when the first PUCCH is the above (2.3.1), the terminal can multiplex all UCI carried by the N PUCCHs into a first target PUCCH, and discard some UCI when the capacity of the first target PUCCH is limited, and then the first target PUCCH can be simultaneously transmitted in an SFN manner using N uplink transmission parameters or N antenna panels (corresponding to the simultaneous transmission of N first target PUCCHs), so that multiple TRPs of the network side device can simultaneously receive the first target PUCCH, thereby improving the flexibility and reliability of transmission.
[0045] Alternatively, in the embodiment of the present application, when the first PUCCH is the above (2.3.2), the terminal can multiplex all UCI carried by the above N PUCCHs into a second target PUCCH, and discard some UCI when the capacity of the second target PUCCH is limited, and then the second target PUCCH can be simultaneously transmitted in a SFN manner using N uplink transmission parameters or N antenna panels (corresponding to the simultaneous transmission of N second target PUCCHs), so that multiple TRPs of the network side device can simultaneously receive the second target PUCCH, thereby improving the flexibility and reliability of transmission.
[0046] In an embodiment of the present application, when the N first uplink objects are N PUCCHs, the N PUCCHs can satisfy any one of a number of conditions, thereby further improving the flexibility of the terminal in determining the N first uplink objects.
[0047] Optionally, in an embodiment of the present application, when the first uplink object is the above (3), the above N first uplink objects are N uplink RSs.
[0048] Optionally, in the embodiment of the present application, the uplink RS may be an SRS, a DMRS, a PTRS, or the like.
[0049] Optionally, in an embodiment of the present application, each set of uplink objects in the above N sets of uplink objects may include at least one uplink object.
[0050] Optionally, in an embodiment of the present application, each set of uplink objects comprises: a. The TRP identifier corresponding to the physical downlink control channel (PDCCH) for scheduling the uplink object is the same; b. The downlink transmission parameters used for the PDCCH for scheduling the uplink object are the same; and c) using the same uplink transmission parameters; d. Using the same antenna panel.

[0053] Optionally, in the embodiment of the present application, the sets of uplink objects may have the same priority or may have different priorities.
[0054] In an embodiment of the present application, each set of uplink objects in the N sets of uplink objects may include at least one uplink object, and each set of uplink objects can satisfy at least one of a plurality of conditions, thereby improving the flexibility of the terminal in determining the N sets of uplink objects corresponding to the at least two uplink objects.
[0055] Optionally, in the embodiment of the present application, the above step 201 may be specifically realized by the following step 201a.
[0056] In step 201a, the terminal determines one first uplink object from each set of uplink objects based on a first rule, and obtains N first uplink objects.
[0057] In an embodiment of the present application, the first rule may be used to discard or multiplex the uplink object.
[0058] For a specific description of the first rule, please refer to the description regarding the discard multiplexing criteria when there is overlap in the transmission times of PUCCH, PUSCH, SRSS, etc. in the relevant protocols, and in order to avoid repetition, it will not be described further here.
[0059] The following provides an exemplary description of an uplink object transmission method according to an embodiment of the present application.
[0060] Exemplarily, when a set of uplink objects includes K uplink objects of PDCCH scheduling corresponding to the same TRP identifier, where K is an integer greater than 1, the terminal may determine one uplink object (i.e., a first uplink object) from the K uplink objects according to a discard multiplexing criterion in a related protocol. Furthermore, the terminal may determine N first uplink objects from the N sets of uplink objects.
[0061] In an embodiment of the present application, the terminal determines one first uplink object from each set of uplink objects based on a first rule for discarding or multiplexing uplink objects, and can obtain N first uplink objects, so that the N first uplink objects determined by the terminal can be the uplink objects transmitted preferentially.
[0062] In step 202, the terminal simultaneously transmits N first uplink objects (one possible implementation), or transmits a second uplink object (another possible implementation).
[0063] In an embodiment of the present application, the second uplink object may be any one of a first target uplink object in the N first uplink objects and a second target uplink object other than the N first uplink objects in the at least two uplink objects.
[0064] Optionally, in the embodiment of the present application, the number of the first target uplink object and the second target uplink object may both be one.
[0065] As can be understood, in an embodiment of the present application, when the first uplink object is (2) above, the first target uplink object corresponds to the first target PUCCH in (2.3.1) above, and the second target uplink object corresponds to the second target PUCCH in (2.3.2) above.
[0066] It should be noted that in practical implementation, the second uplink object may further be an uplink object determined by the terminal from the at least two uplink objects based on a discard multiplexing criterion in a related protocol.
[0067] Optionally, in an embodiment of the present application, the N first uplink objects may be uplink objects that satisfy a first condition.
[0068] Optionally, in an embodiment of the present application, the first condition is: PDCCHs for scheduling uplink objects correspond to different TRP identifiers; a PDCCH for scheduling an uplink object uses different downlink transmission parameters; transmitting using uplink transmission parameters that can be transmitted simultaneously; Transmitting using different antenna panels that can transmit simultaneously; and having the same priority. Optionally, in an embodiment of the present application, if the N first uplink objects satisfy at least one of the first conditions, the terminal can simultaneously transmit the N first uplink objects.
[0069] It can be understood that, if none of the N first uplink objects meets the first condition, the terminal cannot transmit the N first uplink objects simultaneously.
[0070] It should be noted that in an embodiment of the present application, the first condition may be agreed upon by a protocol or configured by a network side, i.e., when the above N first uplink objects satisfy at least one of the first conditions agreed upon by a protocol or configured by the network side, the terminal can transmit the N first uplink objects simultaneously.
[0071] In an embodiment of the present application, the N first uplink objects may be uplink objects that satisfy at least one of a plurality of conditions, and thus, as long as the N first uplink objects satisfy at least one of them, the terminal can simultaneously transmit the N first uplink objects, thereby improving the efficiency of the terminal transmitting the uplink objects.
[0072] Optionally, in an embodiment of the present application, the first condition includes transmitting using different antenna panels that can transmit simultaneously, and in the above possible implementation manner, the above step 202 may be specifically implemented by the following step 202a.
[0073] In step 202a, the terminal uses N first antenna panels to simultaneously transmit N first uplink objects.
[0074] In the embodiment of the present application, the N first antenna panels and the N uplink transmission parameters all correspond one-to-one with the N first uplink objects.
[0075] Optionally, in an embodiment of the present application, each first uplink object in the N first uplink objects may correspond to only one first antenna panel and only one uplink parameter, and the terminal can use the first antenna panel and the corresponding uplink parameter corresponding to each first uplink object to simultaneously transmit the N first uplink objects.
[0076] In an embodiment of the present application, a terminal can use N first antenna panels that correspond one-to-one to the above-mentioned N first uplink objects and N uplink transmission parameters that correspond one-to-one to the above-mentioned N first uplink objects, and can transmit the N first uplink objects simultaneously, thereby realizing the simultaneous transmission of the N first uplink objects and reducing the discarding and scheduling restrictions of uplink information.
[0077] Optionally, in an embodiment of the present application, the N first uplink objects may include M non-scheduled uplink objects, where M is a positive integer less than or equal to N.

[0093] In the uplink object transmission method according to an embodiment of the present application, N first uplink objects or second uplink objects whose transmission times overlap are determined based on N sets of uplink objects corresponding to at least two uplink objects indicated by a network side device to a terminal, and the terminal can simultaneously transmit the N first uplink objects or transmit the N second uplink objects, so there is no need to directly discard or multiplex some uplink objects according to the discard and multiplexing criteria in the related technology, thereby improving the efficiency of the terminal transmitting uplink objects.

[0108] In an embodiment of the present application, the terminal may determine the first target uplink object based on at least one of a plurality of conditions, thereby improving the flexibility of the terminal in determining the first target uplink object.
[0109] Optionally, in an embodiment of the present application, before the above step 201, the uplink object transmission method according to an embodiment of the present application may further include the following step 204.
[0110] In step 204, the terminal dynamically transmits signaling to the network side device.
[0111] In an embodiment of the present application, the signaling is Whether the terminal expects to transmit uplink objects simultaneously; and The terminal may be used to indicate at least one of: expecting the antenna panel to transmit the uplink object;
[0112] Optionally, in an embodiment of the present application, dynamically transmitting the signaling may be transmitting the signaling in the UCI.
[0113] Optionally, in an embodiment of the present application, if the signaling indicates that the terminal expects to transmit uplink objects simultaneously, the network side equipment may, after receiving the signaling, send configured indication information to the terminal to indicate whether the terminal can transmit uplink objects simultaneously.
[0114] Optionally, in an embodiment of the present application, if the signaling indicates that the terminal does not expect to transmit an uplink object simultaneously, the terminal may transmit a second uplink object.
[0115] Optionally, in an embodiment of the present application, if the signaling indicates that the terminal expects an antenna panel for transmitting an uplink object, the network side equipment may measure the interference between the multiple antenna panels after receiving the signaling, and send configured instruction information to the terminal based on the measurement result.
[0116] In an embodiment of the present application, the terminal can dynamically send signaling to the network side equipment to instruct whether the terminal expects to simultaneously transmit an uplink object or not, or that the terminal expects an antenna panel for transmitting the uplink object, so that the network side equipment can send configured instruction information to the terminal based on this signaling, thereby further improving the flexibility of the terminal to transmit the uplink object.
[0117] An embodiment of the present application provides an uplink object transmission method, and Fig. 3 shows a flowchart of the uplink object transmission method according to an embodiment of the present application. As shown in Fig. 3, the uplink object transmission method according to an embodiment of the present application may include the following steps 301 and 302.
[0118] In step 301, a network side device indicates at least two uplink objects to a terminal.
[0119] In step 302, the network side device transmits instruction information to the terminal.
[0120] In an embodiment of the present application, the indication information may be used to indicate that the terminal is in a target state, and the target state may include any one of a state that allows simultaneous transmission and a state that does not allow non-simultaneous transmission.
[0121] Alternatively, in an embodiment of the present application, the indication information may be one bit, which, when this bit is 0, indicates that the terminal is in a state that does not allow non-simultaneous transmission, and when this bit is 1, indicates that the terminal is in a state that allows non-simultaneous transmission.
[0122] Optionally, in an embodiment of the present application, when the instruction information indicates that the terminal is in a state that allows simultaneous transmission, the network side equipment prepares to simultaneously receive the N first target uplink objects, and when the instruction information indicates that the terminal is in a state that does not allow simultaneous transmission, the network side equipment prepares to only receive the second uplink object, or still prepares to simultaneously receive the N first target uplink objects.
[0123] Optionally, in the embodiment of the present application, the indication information may be determined based on the SRS transmitted by the terminal.
[0124] Alternatively, in an embodiment of the present application, the SRS may be used by a network side equipment to measure interference between antenna panels corresponding to the at least two uplink objects, or the network side equipment may be used to measure interference between transmission signals determined by at least two uplink transmission parameters corresponding to the at least two uplink objects.
[0125] As can be understood, when the interference between the transmission signals determined by the antenna panel or at least two uplink transmission parameters corresponding to the at least two uplink objects measured by the network side equipment via the SRS is relatively large, the indication information is used to indicate that the terminal is in a state that does not allow simultaneous transmission, and when the interference between the transmission signals determined by the antenna panel or at least two uplink transmission parameters corresponding to the at least two uplink objects measured by the network side equipment via the SRS is relatively small, the indication information is used to indicate that the terminal is in a state that allows simultaneous transmission.
[0126] In an embodiment of the present application, the indication information may be determined based on the SRS transmitted by the terminal, and the SRS may be used by the network side equipment to measure interference between transmission signals determined by the antenna panel or at least two uplink transmission parameters corresponding to the at least two uplink objects, so that the target state can be dynamically determined based on the interference situation, and the accuracy of the network side equipment in constructing the indication information is improved.
[0127] In the uplink object transmission method according to the embodiment of the present application, the network side device can indicate at least two uplink objects to a terminal, and can transmit indication information to the terminal to indicate that the terminal is in a state that allows simultaneous transmission or a state that does not allow non-simultaneous transmission, so that the terminal can simultaneously transmit N first uplink objects in the at least two uplink objects or transmit a second uplink object in the at least two uplink objects according to the indication information, so that the terminal does not need to directly discard or multiplex some uplink objects from the at least two uplink objects according to the discard multiplexing criteria in the related art, and thus can improve the efficiency of the terminal transmitting uplink objects.
[0128] Optionally, in an embodiment of the present application, before the above step 302, the uplink object transmission method according to an embodiment of the present application may further include the following step 303.
[0129] In step 303, the network side equipment receives the signaling dynamically transmitted by the terminal.
[0130] In an embodiment of the present application, the signaling is Whether the terminal expects to transmit uplink objects simultaneously; and The terminal may be used to indicate at least one of: expecting the antenna panel to transmit the uplink object;
[0131] Optionally, in the embodiment of the present application, the above step 302 may be specifically realized by the following step 302a.
[0132] In step 302a, the network side device sends indication information to the terminal based on the signaling.
[0133] For specific descriptions in the embodiments of the present application, reference may be made to the relevant descriptions in the above embodiments, and in order to avoid repetition, no further description will be given here.
[0134] In an embodiment of the present application, the network side equipment can receive signaling dynamically sent by a terminal as to whether the terminal expects to simultaneously transmit an uplink object, or whether the terminal expects an antenna panel for transmitting an uplink object, and can send instruction information to the terminal based on this signaling, thereby improving the accuracy with which the network side equipment sends the instruction information.
[0135] The uplink object transmission method according to the embodiment of the present application may be executed by an uplink object transmission device, or may be executed by a control module for executing the uplink object transmission method in the uplink object transmission device. In the embodiment of the present application, the uplink object transmission device according to the embodiment of the present application will be described as an example in which the uplink object transmission device executes the uplink object transmission method.
[0136] Referring to FIG. 4, an embodiment of the present application provides an uplink object transmission device 40, which may include a determining module 41 and a transmitting module 42. The determining module 41 may be used to determine N first uplink objects having overlapping transmission times from at least two uplink objects in one time unit indicated by a network side device, where N is an integer greater than 1. The transmitting module 42 may be used to simultaneously transmit the N first uplink objects or to transmit a second uplink object. Here, each first uplink object in the N first uplink objects belongs to a set of uplink objects among the N sets of uplink objects, each of which corresponds to at least two uplink objects. The first uplink object is at least one of a PUSCH, a PUCCH, and an uplink RS. The second uplink object is either a first target uplink object among the N first uplink objects or a second target uplink object other than the N first uplink objects among the at least two uplink objects.
[0137] In one possible implementation manner, each set of uplink objects in the N sets of uplink objects may include at least one uplink object, and each set of uplink objects may satisfy at least one of the following: TRP identifiers corresponding to PDCCHs for scheduling the uplink objects are the same, downlink transmission parameters used in PDCCHs for scheduling the uplink objects are the same, the uplink transmission parameters are used, and the antenna panel is used.
[0138] In one possible implementation manner, the N first uplink objects may be uplink objects that satisfy a first condition, where the first condition may include at least one of: PDCCHs for scheduling the uplink objects correspond to different TRP identifiers; PDCCHs for scheduling the uplink objects use different downlink transmission parameters; transmit using uplink transmission parameters that can be transmitted simultaneously; transmit using different antenna panels that can be transmitted simultaneously; and have the same priority.
[0139] In one possible implementation, the first condition includes transmitting using different antenna panels that can transmit simultaneously. The transmitting module 42 may specifically use N first antenna panels to transmit the N first uplink objects simultaneously, where the N first antenna panels correspond one-to-one with the N first uplink objects.
[0140] In one possible implementation manner, the N first uplink objects may include M non-scheduled uplink objects, where M is a positive integer equal to or less than N. A correspondence relationship between each non-scheduled uplink object in the M non-scheduled uplink objects and a set of uplink objects in the N sets of uplink objects may be determined based on one of a plurality of first transmission features configured by a network side device, one of a plurality of first transmission features activated by a network side device, or one of a plurality of first transmission features indicated by a network side device, where the first transmission feature may include at least one of a TRP identifier corresponding to a PDCCH for scheduling the uplink object, a downlink transmission parameter used for a PDCCH for scheduling the uplink object, an uplink transmission parameter used for transmission, an antenna panel used for transmission, and a priority.
[0141] In one possible implementation, the N first uplink objects are N PUSCHs. Each PUSCH in the N PUSCHs may include any one of a single PUSCH, a single transmission in PUSCH repetition transmission, and a PUSCH transmission of one TB among a plurality of TBs of PUSCH transmissions scheduled at one time. The N PUSCHs can satisfy at least one of the following: a sum of the ranks or layers of the N PUSCHs is equal to or less than a preset threshold; the SLIVs corresponding to the N PUSCHs are the same; the scrambling code sequences corresponding to the N PUSCHs are different; the target reference signals of the N PUSCHs belong to different code division multiplexing groups of the target reference signals; the RE corresponding to one PUSCH in each of the two PUSCHs does not overlap with the RE occupied by the target reference signal corresponding to the other PUSCH in each of the two PUSCHs, and the one PUSCH performs rate matching on the target reference signal corresponding to the other PUSCH. Here, the target reference signal may be a DMRS or a PTRS.
[0142] In one possible implementation manner, the N first uplink objects are N PUCCHs, which can satisfy any one of the following: resources of the N PUCCHs do not overlap in frequency domain; the N PUCCHs are PUCCHs simultaneously transmitted using N uplink transmission parameters or N antenna panels; and the N PUCCHs are PUCCHs simultaneously transmitted using N uplink transmission parameters or N antenna panels in SFN mode. Here, the first PUCCH can be any one of a first target PUCCH in the N PUCCHs and a second target PUCCH other than the N PUCCHs in the at least two uplink objects re-determined by the determination module 41.
[0143] In one possible implementation manner, the determination module 41 may be specifically used to determine one first uplink object from each set of uplink objects based on a first rule to obtain the N first uplink objects, where the first rule is used to discard or multiplex the uplink object.
[0144] In one possible implementation, the transmitting module 42 may be used to transmit the N first uplink objects simultaneously when the terminal is in a state that allows simultaneous transmission, and the transmitting module 42 may be used to transmit the second uplink object when the terminal is in a state that does not allow simultaneous transmission.
[0145] In one possible implementation manner, the terminal being in a state allowing the simultaneous transmission may be determined based on either: the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter; the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter and receiving indication information allowing simultaneous transmission of MAC CE or indication information allowing simultaneous transmission of DCI. The terminal being in a state not allowing the simultaneous transmission may be determined based on either: the terminal receiving non-simultaneous transmission state indication information semi-statically configured by an RRC parameter; the terminal not receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter; or the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter and receiving indication information not allowing simultaneous transmission of MAC CE or indication information not allowing simultaneous transmission of DCI.
[0146] In one possible implementation, the second uplink object is the first target uplink object, and the determining module 41 may be further used to determine the first target uplink object according to a target order before the sending module 42 sends the second uplink object.
[0147] In one possible implementation manner, the target order may be determined based on at least one of the uplink objects scheduled by a TRP agreed upon by a protocol or configured by a network, the uplink objects determined by the determination module 41, whether the uplink object multiplexes UCI, the high or low priority of the UCI carried in the uplink object, the high or low transmission priority of the uplink object, before or after the transmission start time of the uplink object, before or after the start or end time of the scheduled PDCCH of the uplink object, the size of the MCS of the uplink object, and the size of the Rank or Layer of the uplink object.
[0148] In one possible implementation, the sending module 42 may further be used to dynamically send signaling to the network side device before the determining module 41 determines the N first uplink objects with overlapping transmission times from the at least two uplink objects in the target slot indicated by the network side device, where the signaling may be used to indicate at least one of whether the terminal expects the uplink objects to be transmitted simultaneously and that the terminal expects the antenna panel to transmit the uplink objects.
[0149] In an uplink object transmitting device according to an embodiment of the present application, N first uplink objects or second uplink objects whose transmission times overlap are determined based on N sets of uplink objects corresponding to at least two uplink objects instructed by a network side device to which the uplink object transmitting device is directed, and the uplink object transmitting device can simultaneously transmit the N first uplink objects or transmit the second uplink object, so there is no need to directly discard or multiplex some uplink objects in accordance with the discard and multiplexing standards in related technologies, thereby improving the efficiency of transmitting uplink objects.
[0150] The uplink object transmission device in the embodiment of the present application may be an electronic device, for example an electronic device having an operating system, or may be a component in an electronic device, for example an integrated circuit or a chip. The electronic device may be a terminal, or other devices other than a terminal. Exemplarily, the terminal may include, but is not limited to, the types of terminal 11 listed above, and the other devices may be a server, a network attached storage (NAS), etc., and the embodiment of the present application is not specifically limited.
[0151] The uplink object transmitting device according to the embodiment of the present application can realize each process realized by the terminal in the embodiment of the above method and achieve the same technical effect, and will not be described further here in order to avoid repetition of description.
[0152] Referring to Fig. 5, an embodiment of the present application provides an uplink object transmitting device 50, which may include an indication module 51 and a transmitting module 52. The indication module 51 may be used to indicate at least two uplink objects to a terminal. The transmitting module 52 may be used to transmit indication information to the terminal, where the indication information may be used to indicate that the terminal is in a target state, and the target state may include any one of a state that allows simultaneous transmission and a state that does not allow non-simultaneous transmission.
[0153] In one possible implementation manner, the uplink object transmitting device 50 may further include a measurement module. The indication information may be determined based on an SRS transmitted by a terminal, where the SRS may be used by the measurement module to measure interference between antenna panels corresponding to the at least two uplink objects, or the SRS may be used by the measurement module to measure interference between transmission signals determined by at least two uplink transmission parameters corresponding to the at least two uplink objects.
[0154] In one possible implementation, the uplink object transmitting device 50 may further include a receiving module. The receiving module may be used to receive a signaling dynamically transmitted by the terminal before the transmitting module 52 transmits the indication information to the terminal, where the signaling may be used to indicate at least one of whether the terminal expects to transmit the uplink object simultaneously and that the terminal expects the antenna panel to transmit the uplink object. The transmitting module 52 may be used to transmit the indication information to the terminal specifically based on the signaling.

As can be understood, the modem processor does not have to be integrated into the processor 1010.
[0165] Here, the processor 1010 may be used to determine N first uplink objects having overlapping transmission times from at least two uplink objects in one time unit indicated by the network side device, where N is an integer greater than 1. The radio frequency unit 1001 may be used to simultaneously transmit the N first uplink objects, or may be used to transmit the second uplink object.

The first uplink object is at least one of a PUSCH, a PUCCH, and an uplink RS. The second uplink object is any one of a first target uplink object in the N first uplink objects and a second target uplink object other than the N first uplink objects in the at least two uplink objects.

The radio frequency unit 1001 may specifically use N first antenna panels to transmit the N first uplink objects simultaneously, where the N first antenna panels correspond one-to-one with the N first uplink objects.
[0169] In one possible implementation manner, the N first uplink objects may include M non-scheduled uplink objects, where M is a positive integer equal to or less than N. A correspondence relationship between each non-scheduled uplink object in the M non-scheduled uplink objects and a set of uplink objects in the N sets of uplink objects may be determined based on one of a plurality of first transmission features configured by a network side device, one of a plurality of first transmission features activated by a network side device, or one of a plurality of first transmission features indicated by a network side device, where the first transmission feature may include at least one of a TRP identifier corresponding to a PDCCH for scheduling the uplink object, a downlink transmission parameter used for a PDCCH for scheduling the uplink object, an uplink transmission parameter used for transmission, an antenna panel used for transmission, and a priority.

The N PUSCHs can satisfy at least one of the following: a sum of the ranks or layers of the N PUSCHs is equal to or less than a preset threshold; the SLIVs corresponding to the N PUSCHs are the same; the scrambling code sequences corresponding to the N PUSCHs are different; the target reference signals of the N PUSCHs belong to different code division multiplexing groups of the target reference signals; the RE corresponding to one PUSCH in each of the two PUSCHs does not overlap with the RE occupied by the target reference signal corresponding to the other PUSCH in each of the two PUSCHs, and the one PUSCH performs rate matching on the target reference signal corresponding to the other PUSCH. Here, the target reference signal may be a DMRS or a PTRS.
[0171] In one possible implementation manner, the N first uplink objects are N PUCCHs, which can satisfy any one of the following: resources of the N PUCCHs do not overlap in frequency domain; the N PUCCHs are PUCCHs simultaneously transmitted using N uplink transmission parameters or N antenna panels; and the N PUCCHs are PUCCHs simultaneously transmitted in SFN manner using N uplink transmission parameters or N antenna panels. Here, the first PUCCH can be any one of a first target PUCCH in the N PUCCHs and a second target PUCCH other than the N PUCCHs in the at least two uplink objects re-determined by the processor 1010.
[0172] In one possible implementation, the processor 1010 may be specifically used to determine one first uplink object from each set of uplink objects based on a first rule to obtain the N first uplink objects, where the first rule is used to discard or multiplex the uplink object.
[0173] In one possible implementation manner, the radio frequency unit 1001 is specifically used for simultaneously transmitting the N first uplink objects when the terminal is in a state that allows simultaneous transmission, and the radio frequency unit 1001 may be specifically used for transmitting the second uplink object when the terminal is in a state that does not allow simultaneous transmission.
[0174] In one possible implementation manner, the terminal being in a state allowing the simultaneous transmission may be determined based on either: the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter; the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter and receiving indication information allowing simultaneous transmission of MAC CE or indication information allowing simultaneous transmission of DCI. The terminal being in a state not allowing the simultaneous transmission may be determined based on either: the terminal receiving non-simultaneous transmission state indication information semi-statically configured by an RRC parameter; the terminal not receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter; or the terminal receiving simultaneous transmission state indication information semi-statically configured by an RRC parameter and receiving indication information not allowing simultaneous transmission of MAC CE or indication information not allowing simultaneous transmission of DCI.
[0175] In one possible implementation, the second uplink object is the first target uplink object, and the processor 1010 may be further used to determine the first target uplink object according to a target order before the radio frequency unit 1001 transmits the second uplink object.
[0176] In one possible implementation manner, the target order may be determined based on at least one of the uplink objects scheduled by a TRP agreed upon by a protocol or configured by a network, the uplink objects determined by the processor 1010, whether the uplink object multiplexes UCI, the high or low priority of the UCI carried in the uplink object, the high or low transmission priority of the uplink object, before or after the transmission start time of the uplink object, before or after the start or end time of the scheduled PDSCH of the uplink object, the size of the MCS of the uplink object, and the size of the Rank or Layer of the uplink object.
[0177] In one possible implementation, the radio frequency unit 1001 may further be used to dynamically send signaling to the network side device before the processor 1010 determines the N first uplink objects having overlapping transmission times from the at least two uplink objects in the target slot indicated by the network side device, where the signaling may be used to indicate at least one of whether the terminal expects the uplink objects to be transmitted simultaneously and that the terminal expects the antenna panel to transmit the uplink objects.
