Embodiment 1

[0101] Embodiment 1: Indicate through cell-specific (or time slot-specific) signaling

[0102] The NR cell / base station may transmit cell-specific notification information (the aforementioned DL preemption indication information) for resources on which puncturing for eMBB data is performed or resources on which eMBBDL data and URLLC DL data are superimposed on each other for URLLC data is transmitted in time-domain scheduling units (eg, slots or aggregated slots) defined for eMBB UEs. In addition, the base station may transmit the DL preemption indication information in a UE common signaling manner or a UE group common signaling manner.

[0103] Specifically, when pre-notification-based dynamic puncturing or post-notification-based dynamic puncturing is applied, the base station can use cell-specific or UE common / UE group common signaling to perform Information about the resource on which URLLC data was transmitted in the previous slot (when post-notification is applied) or...

Embodiment 2

[0109] Embodiment 2: UE-specific or timeslot-specific indication

[0110] The NR cell / base station can transmit UE-specific notification information (DL preemption indication information) for resources on which puncturing of eMBB data is performed or resources on which eMBB DL data and URLLC DL data are superimposed on each other The URLLC data is transmitted in time-domain scheduling units (for example, time slots or aggregated time slots) defined by the eMBB UE.

[0111] Specifically, when pre-notification-based dynamic puncturing or post-notification-based dynamic puncturing is applied, for eMBB UEs for DL ​​data resource allocation, in case one or more of the resources allocated for transmitting the corresponding data are used for transmitting URLLC data, this may be performed per eMBB UE by enabling UE-specific signaling Unicast to perform.

[0112] For example, in the case of applying the pre-notification method, transmission of DL (or UL) for the corresponding UE in...

Abstract

The present invention relates to a method and apparatus for transmitting and receiving a downlink signal for supporting effective multiplexing between data traffic having mutually different QoS requirements in a next generation / 5G wireless access network ("New Radio" (NR)) for which discussion has begun in 3GPP. A method for a terminal receiving a downlink signal according to one embodiment comprises the steps of: receiving configuration data for receiving downlink pre-emption indication data from a base station; monitoring the downlink pre-emption indication data on the basis of the configuration data; and receiving the downlink pre-emption indication data by means of a multicast or unicast signal, wherein the downlink pre-emption indication data comprises data for indicating the overlapping wireless resource between a wireless resource for providing a first service, and a wireless resource for providing a second service.

Description

technical field [0001] The present invention relates to a method for transmitting and receiving downlink signals in the next generation / 5G radio access network (“New Radio” (NR)) discussed in the 3rd Generation Partnership Project (3GPP) for use in each A method and apparatus for supporting efficient multiplexing between data services having different QoS requirements from each other. Background technique [0002] Recently, 3GPP has approved a research project "Study on New Radio Access Technology" for studying next generation / 5G radio access technology. On the basis of research on new radio access technologies, Radio Access Network Working Group 1 (RAN WG1) has discussed frame structures, channel coding and modulation, waveforms, multiple access methods for new radio (NR) Wait. NR is required to be designed not only to provide improved data transfer rates compared to Long Term Evolution (LTE) / LTE-Advanced (LTE-Advanced), but also to meet various requirements in concrete a...
