Title
(EN) COVERAGE ENHANCEMENT METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'AMÉLIORATION DE COUVERTURE
(ZH) 一种覆盖增强方法和装置
Abstract
(EN) The present application relates to a coverage enhancement method and device. The method comprises: transmitting N first SSB beams in a first SSB beam set on a first initial bandwidth part (BWP) resource, and transmitting M second SSB beams in a second SSB beam set on a second initial BWP resource, wherein a coverage range of the first SSB beam set is located in a first partial region of a sector, a coverage range of the second SSB beam set is located in a second partial region of the sector, and N and M are positive integers. Thus, the coverage gain of the SSB beams of the sector is improved by complementary coverage of the first SSB beams and the second SSB beams within the sector.
(FR) La présente demande concerne un procédé et un dispositif d'amélioration de couverture. Le procédé consiste à : transmettre N premiers faisceaux de SSB dans un premier ensemble de faisceaux de SSB sur une première ressource de partie de bande passante (BWP) initiale et transmettre M seconds faisceaux de SSB dans un second ensemble de faisceaux de SSB sur une seconde ressource de BWP initiale, une plage de couverture du premier ensemble de faisceaux de SSB étant située dans une première région partielle d'un secteur, une plage de couverture du second ensemble de faisceaux de SSB étant située dans une seconde région partielle du secteur et N et M représentant des nombres entiers positifs. Ainsi, le gain de couverture des faisceaux de SSB du secteur est amélioré par une couverture complémentaire des premiers faisceaux de SSB et des seconds faisceaux de SSB au sein du secteur.
(ZH) 本申请涉及一种覆盖增强方法和装置。该方法包括:在第一初始部分带宽BWP资源上发射第一SSB波束集合中的N个第一SSB波束;在第二初始BWP资源上发射第二SSB波束集合中的M个第二SSB波束;其中,所述第一SSB波束集合的覆盖范围位于扇区的第一部分区域;所述第二SSB波束集合的覆盖范围位于所述扇区的第二部分区域;所述N,M为正整数。从而,使得扇区内由第一SSB波束和第二SSB波束互补覆盖,提高扇区的SSB波束的覆盖增益。
