Title:
狭帯域デバイス向けのマルチキャストサービス送信のための周波数ホッピング
Document Type and Number:
Japanese Patent JP6912563
Kind Code:
B2
Abstract:
Various features related to frequency hopping for broadcast/multicast transmissions for narrow band devices are described. To exploit frequency diversity, multicast transmissions may be frequency hopped. In an aspect, a UE maybe configured to receive a signal, e.g., from a base station, including at least one of a first hopping indicator indicating whether frequency hopping is enabled for a multicast control channel or a second hopping indicator indicating whether frequency hopping is enabled for a multicast traffic channel, and determine whether frequency hopping is enabled for the at least one of the multicast control or traffic channel based on the received signal. The UE may further determine at least one hopping pattern for receiving multicast transmissions in the at least one of the multicast control channel or the multicast traffic channel when the frequency hopping is enabled, and receive the multicast transmissions based on the determined at least one hopping pattern.
