Currently, a terminal supports at most 2 Transmission (TX) transmission when performing uplink transmission. In Release-18 (rel-18) multi-carrier (multi-carrier) enhancement (enhancement) project, it is determined to enhance UpLink (UL) TX switching. Specifically, the terminal supports UL TX switching between 3 or 4 bands (bands). When the terminal supports SUL transmission, only one normal uplink band and one supplementary uplink band can be supported, as shown in fig. 1.
The terminal determines the band where the uplink transmission is located according to a 1-bit (bit) UL/SUL indicator (indicator) carried in downlink control information (Downlink Control Information, DCI). The uplink indicated by the bit value of the UL/SUL indicator is shown in table 1.
TABLE 1
If a normal uplink (SUL) is configured with multiple SULs, the current mechanism cannot determine the SUL of the multiple SULs where the uplink is located.
In order to solve the above technical problems, the present disclosure provides the following uplink transmission method. The uplink transmission method provided by the present disclosure is first described from the terminal side.

In the embodiment of the present disclosure, the first indication information may be an UL/SUL indicator, and the first indication information may occupy 1 bit in DCI.
The format of the DCI may be a DCI format (format) of non-fallback (non-fallback), for example, DCI format 0-1, DCI format 0-2. Alternatively, the format of the DCI may be a retrogressive DCI format, such as DCI formats 0-0, which is not limited in this disclosure.
In one possible implementation manner, when the bit value corresponding to the first indication information is 0, the terminal is instructed to perform uplink transmission on a common uplink. And when the bit value corresponding to the first indication information is 1, the indication terminal performs uplink transmission on the SUL.
In step 302, in a case where the first indication information indicates that the terminal performs uplink transmission on the SUL, the number of the target SUL is determined based on a contract among the SULs.

In one possible implementation, the number of bits occupied by the second indication information in the DCI may be greater than 1, and specifically may be a positive integer greater than 1, for example, 2, 3, … …, etc., which is not limited by the present disclosure.

Wherein the bit value of the second indication information and the indicated uplink number are for example shown in table 2.

In order to facilitate understanding of the uplink transmission method provided in the present disclosure, the following further exemplifies the above method.
Embodiment 1, in which a terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example.
In this embodiment, the base station may send, through the second RRC signaling, third indication information to the terminal, where the third indication information is used to indicate the number of the activation supplementary uplink corresponding to normal uplink band. The terminal and the base station take the SUL in the activated state as a target SUL. In other words, if the SUL in supplementary list (i.e., a SUL list composed of a plurality of SULs) is not indicated as an active state by the second RRC signaling, the terminal does not transmit an uplink transmission thereon, nor is the base station side expected to receive an uplink transmission thereon.
Assume that the second RRC signaling activates the SUL with log2 (N) bits, where N is the number of SULs contained in the SUL list, i.e., the number of multiple SULs. In this embodiment, N may be 2. The SUL in the active state indicated by the second RRC signaling is shown in table 3, for example.
TABLE 3 Table 3
In this embodiment, it is assumed that the second RRC signaling indicates that sul#1 is in an active state. The terminal determines to perform uplink transmission on the normal uplink or sul#1 according to the first indication information sent by the base station through the DCI.
Taking a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) as an example, assume that a base station transmits DCI for scheduling PUSCH, and the DCI is format 0-1, where first indication information carried therein, i.e. UL/SUL indicator, indicates that the PUSCH needs to be transmitted on SUL. At this time, since SUL#1 is in an active state, the terminal transmits the PUSCH on SUL#1 according to the scheduling information. Correspondingly, the base station receives the PUSCH on sul#1.
Embodiment 2, in which the terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example.
In this embodiment, the base station may send the first indication information through DCI, and its PUSCH is scheduled by DCI formats 0-0. At this time, when the first indication information, i.e., the UL/SUL indicator, carried in the DCI format 0-0 indicates that the terminal performs uplink transmission on the SUL, the terminal and the base station may take the sul#1 as the target SUL according to the protocol convention.
In this embodiment, the base station may also send the second indication information through DCI to directly indicate the number of the common uplink or the number of the target SUL. The information domain where the UL/SUL indicator carried in the DCI is located can be expanded. Specifically, the number of bits occupied by the UL/SUL indicator is expanded from 1bit to at least 2 bits. And determining that the frequency band where the uplink transmission scheduled by the DCI is located is NUL, SUL#1 or SUL#2 through the second indication information of at least 2 bits. The bit value of the second indication information and the indicated uplink number are shown in table 2, for example, and are not described here again.
In this embodiment, assuming that a set of bit values corresponding to the second indication information is 10, the terminal and the base station may determine that the PUSCH scheduled by the DCI is transmitted on sul#2.
Further, the second indication information is carried by non-fallback DCI format, i.e. only by DCI format 0-1 or DCI format 0-2.
Embodiment 3, in which the terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example.
In this embodiment, the base station sends third indication information to the terminal through MAC CE signaling, where the third indication information is used to indicate the SUL in an active state corresponding to the common uplink. The terminal and the base station may take the SUL in the active state as a target SUL.
In other words, if the SUL in supplementary list is not indicated as active by the third indication information in the MAC CE signaling, the terminal does not transmit an uplink transmission thereon, nor is the base station side expecting to receive an uplink transmission thereon.
In this embodiment, it is assumed that the third indication information in the MAC CE signaling indicates that sul#1 is in an active state. The terminal determines to perform uplink transmission on NUL or sul#1 according to the first indication information sent by the base station through DCI.
Taking PUSCH as an example, assume that the base station transmits DCI format 0-1 for scheduling PUSCH, where the carried UL/SUL indicator indicates that the PUSCH needs to be transmitted on SUL. At this time, since SUL#1 is an active SUL, the terminal transmits the PUSCH on SUL#1 according to the scheduling information. Correspondingly, the base station receives the PUSCH on sul#1.
Embodiment 4, in which the terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example. Only one supplementary uplink is active at the same time. In this embodiment, supplementary uplink is determined to be active at a particular time by defining supplementary uplink related timer.
In this embodiment, it is assumed that SUL#1 and SUL#2 have two independently configured timers, i.e., SUL#1 corresponds to timer#1 and SUL#2 corresponds to timer#2, and that both timers cannot be started at the same time, i.e., only after the timer on the SUL in the active state times out (expire), can the timer on the other SUL be started and correspondingly enter the active state.
In this embodiment, it is assumed that the terminal receives the first indication information sent by the base station at the target time point, and determines that sul#1 is activated supplementary uplink according to the timer. The terminal determines to perform uplink transmission on NUL or sul#1 according to the first instruction information sent by the base station side.
Taking PUSCH as an example, assume that the base station transmits DCI format 0-1 for scheduling PUSCH, and the first indication information UL/SUL indicator carried therein indicates that the PUSCH needs to be transmitted on SUL. At this time, since SUL#1 is an active SUL, the terminal transmits the PUSCH on SUL#1 according to the scheduling information. Correspondingly, the base station receives the PUSCH on sul#1.
Embodiment 5, in which the terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example. Only one supplementary uplink is active at the same time. In this embodiment, supplementary uplink is determined to be active at a particular time by defining supplementary uplink related timer.
At the same point in time, only one supplementary uplink is active. In this embodiment, the target SUL is implicitly determined.
Specifically, different values of the same type of association identifier correspond to different SULs, and the association identifier includes at least one of the following: transmitting a bandwidth part BWP identification of the DCI; transmitting the Search Space (SS) identification of the DCI; and transmitting a control resource set CORESET identifier of the DCI.
For example, ss#1 corresponds to sul#1 and ss#2 corresponds to sul#2.
The DCI scheduled PUSCH is transmitted on sul#1 when the following condition is satisfied:
the first indication information UL/SUL indicator in the DCI is 1, that is, indicates that its scheduled uplink transmission is transmitted on SUL, and the DCI is transmitted in ss#1
The DCI scheduled PUSCH is transmitted on sul#2 when the following condition is satisfied:
the UL/SUL indicator in the DCI is 1, i.e. indicates that its scheduled uplink transmission is transmitted on SUL, and the DCI is transmitted in ss#2.
Further, each SUL may be associated with one or more SSs, and the present patent is not limited in any way.
Embodiment 6, in which the terminal is assumed to support a plurality of SULs, it is assumed that the number of SULs supported by the terminal is 2, that is, one normal uplink corresponds to two supplementary uplink, as shown in fig. 17A, for example. Only one supplementary uplink is active at the same time. In this embodiment, supplementary uplink is determined to be active at a particular time by defining supplementary uplink related timer.
Only one SUL is active at the same time. In this embodiment, by configuring time patterns (time patterns) for the SULs, respectively, the SUL whose target time point is in an activated state is taken as the target SUL.
As a specific example, the base station configures the SUL time pattern period and indicates the activation status of different SULs in the period, for example, as shown in fig. 17B. Taking PUSCH as an example, assume that the base station transmits DCI format 0-1 for scheduling PUSCH, and the UL/SUL indicator carried therein indicates that the PUSCH needs to be transmitted on SUL. The target SUL for PUSCH transmission is the SUL which is in an activated state at the target time point and is determined according to the SUL time pattern.
In the above embodiment, the target SUL for uplink transmission of the terminal can be quickly determined under the condition that one common uplink corresponds to a plurality of SULs, so as to ensure that the understanding of the base station and the terminal are consistent, improve the flexibility of network deployment and scheduling, realize uplink transmission switching enhancement in the NR system, and have high availability.
