Abstract: An operation method of a user equipment based on non-terrestrial network (NTN) communication includes: performing channel estimation of a first broadcast channel included in a first frame; performing initial channel estimation of system information included in the first frame; performing channel estimation of a second broadcast channel included in a second frame which is subsequent to the first frame; determining a first weight corresponding to the system information, a second weight corresponding to the first broadcast channel, and a third weight corresponding to the second channel; and calculating a channel estimate of the system information based on results of the channel estimation of the first broadcast channel, the initial channel estimation of the system information and the channel estimation of the second broadcast channel, and the first weight through the third weight.

Abstract: L'invention concerne un tel point d'accès (10) comprenant:
- un module de détermination (12) d'une distorsion de signal causée par ses propres imperfections matérielles,
- un module de transmission (14), via une liaison fronthaul comprenant une pluralité de points d'accès en série ordonnés selon un sens de parcours prédéterminé jusqu'à l'unité centrale d'une station de base, de ladite distorsion à un autre point d'accès, ou à l'unité centrale, le suivant au sein de ladite liaison fronthaul; et/ou
- un module de réception (16), et de prise en compte de ladite distorsion d'un point d'accès le précédant au sein de ladite liaison fronthaul, pour déterminer les filtres de précodage locaux dudit point d'accès configurés pour annuler ladite distorsion dudit point d'accès le précédant.

Abstract: An apparatus configured to be employed in an eNodeB associated with a machine type communication (MTC) system is disclosed. The apparatus comprises one or more processors configured to configure a mapping between cell-specific reference signal (CRS) antenna ports and demodulation reference signals (DMRS) antenna ports for an MTC physical downlink control channel (MPDCCH) associated with a UE, forming a CRS-to-DMRS antenna port mapping, to be provided to the UE, in order to enable the UE to perform coherent demodulation of the MPDCCH, based on CRS and DMRS. The one or more processors is further configured to generate a physical channel configuration signal comprising one or more mapping information parameters indicative of the CRS-to-DMRS antenna port mapping, in order to provide information on the CRS-to-DMRS antenna port mapping to the UE.
