Abstract:
(EN) A method for receiving, by a terminal, downlink control information according to one embodiment of the present invention may comprise: receiving bundling information on REGs through upper-layer signaling; performing blind detection for PDCCH within a CORESET set on a plurality of OFDM symbols; and obtaining a DCI from the PDCCH. The terminal can: bundle, into one REG bundle, only REGs that are located on the same RB within the CORESET and correspond to other OFDM symbols, if the bundling information indicates a first value; bundle together, into one REG bundle, REGs that are located on the same RB within the CORESET and correspond to other OFDM symbols, as well as REGs that are located on another RB, if the bundling information indicates a second value; and perform blind detection for the PDCCH, assuming the same precoding for REGs which fall within the same REG bundle on the basis of a REG bundling result.
(FR) Un procédé servant à recevoir, par un terminal, des informations de commande de liaison descendante selon un mode de réalisation de la présente invention peut comprendre : la réception d'informations de groupage concernant des REG au moyen d'une signalisation de couche supérieure ; la réalisation d'une détection à l'aveugle d'un PDCCH dans un ensemble CORESET sur une pluralité de symboles OFDM ; et l'obtention d'une DCI à partir du PDCCH. Le terminal peut : regrouper en un faisceau REG seuls des REG qui sont situés sur le même RB dans le CORESET et qui correspondent à d'autres symboles OFDM si les informations de groupage indiquent une première valeur ; regrouper en un groupe REG des REG qui sont situés sur le même RB dans le CORESET et qui correspondent à d'autres symboles OFDM, ainsi que des REG qui sont situés sur un autre RB, si les informations de groupage indiquent une seconde valeur ; et effectuer une détection à l'aveugle du PDCCH, en supposant le même précodage pour les REG qui se trouvent dans le même groupe REG sur la base d'un résultat de groupage REG.
(KO) 본 발명의 일 실시예에 따라 단말이 하향링크 제어 정보를 수신하는 방법은, REG들에 대한 번들링 정보를 상위 계층 시그널링을 통해 수신하고, 복수의 OFDM 심볼들 상에 설정된 CORESET 내에서 PDCCH에 대한 블라인드 검출을 수행하고, 상기 PDCCH로부터 DCI를 획득하는 것을 포함할 수 있다. 단말은 상기 번들링 정보가 제1 값을 지시하면 상기 CORESET 내에서 동일 RB 상에 위치하고 다른 OFDM 심볼들에 해당하는 REG들만 하나의 REG 번들로 번들링하고, 상기 번들링 정보가 제2 값을 지시하면 상기 CORESET 내에서 상기 동일 RB 상에 위치하고 다른 OFDM 심볼들에 해당하는 REG들 뿐 아니라 다른 RB 상에 위치하는 REG들을 함께 하나의 REG 번들로 번들링하며, REG 번들링 결과에 의해 동일 REG 번들에 속하는 REG들에 대하여 동일한 프리코딩을 가정하고 상기 PDCCH에 대한 블라인드 검출을 수행할 수 있다.
