摘要

The method and device for transmitting and receiving signals in a wireless communication system, according to one embodiment of the present invention, comprise: receiving downlink control information (DCI) for scheduling a single physical uplink shared channel (PUSCH) or a plurality of PUSCHs to be transmitted on a serving cell; and transmitting the single PUSCH or the plurality of PUSCHs on the serving cell on the basis of the DCI, wherein the payload size of the DCI may be determined on the basis of the larger one of the number of bits of the pieces of information for scheduling the single PUSCH and the number of bits of the pieces of information for scheduling the plurality of PUSCHs.

說(shuō)明書(shū)

1. When the total number of symbols from the symbol index S in the first slot to the last symbol index in the first slot is defined as X, it is configured that L=N_p?(N_s?1)=Np?(N_m+1) and duration D=X/L (or floor (X/L) or ceiling (X/L)).

2. Sub-slot duration PUSCHs of the duration D are repeatedly mapped L times so that the PUSCHs are adjacent to each other, starting from the symbol index S in the first slot (to the in-slot last symbol only in the first slot).

a. In this case, the slot-filling method may be applied to repetition/mapping of the sub-slot duration PUSCHs of the duration D in the corresponding first slot.

3. To configure a slot set, consecutive N_p?L?1 slots are determined as middle slots starting from K+1, which is the slot index immediately following the first slot, and K+N_p?L, which is the slot index immediately following the last middle slot among the middle slots, is determined as the last slot.

II. Step 2

1. For the first slot in the slot set, one or more L sub-slot duration PUSCH resources mapped to the corresponding first slot are determined as L individual/independent PUSCH resources, respectively.

III. Step 3

1. For the last slot in the slot set, a single PUSCH resource having a duration from the first symbol index in the corresponding last slot to the indicated symbol index E is allocated.

a. In 1 of Step 3, the symbol index E may be indicated as one of the following: 1) a symbol index S+O1 obtained by applying a symbol offset O1 to the symbol index S and 2) a symbol index L+O2 obtained by applying a symbol offset O2 to a last symbol index L in the slot. Alternatively, the symbol index E may be determined as one of the symbol indices without separate signaling.
