Embodiment Construction

[0072] Several embodiments will be described below. In addition, in the following description, a base station, a relay station, and a mobile station are abbreviated as eNB, RN, and UE, respectively, as appropriate. The base station eNB in ​​this embodiment is a donor base station (Donor eNB or DeNB) that supports backhaul with the relay station RN.

[0073] In the following description, a "backhaul interval" refers to one or more intervals among a plurality of intervals set in units of TTI (Transmission Time Interval) in a single radio frame. In the present embodiment, TTI is defined as time in units of subframes (1 ms). "Setting the backhaul" may mean setting or determining the backhaul as a subframe in the radio frame. Also, this embodiment can be applied even when TTI is not a time in units of subframes. That is, TTI originally means "the time required to transmit a transport block (Transport Block)", and a subframe originally means "a section in which radio resources ar...

Abstract

Provided is a mobile communication system wherein a mobile relay station sets a common restricted communication period to mobile stations (UE) under control of the mobile relay station (RN) during a period from the detection of a handover till the application of a new backhaul connected to a base station that is a destination of the handover. For example, during a restricted communication period, such as Measurement gap, the mobile stations under control of the mobile relay station do not perform data transmissions/receptions, so that a back-haul can be set during the Measurement gap.

Description

technical field [0001] The invention relates to the relay technology of wireless communication between a base station and a mobile station. Background technique [0002] In the cellular mobile communication system, the development from UMTS (Universal Mobile Telecommunication System: Universal Mobile Communication System) to LTE (Long Term Evolution: Long Term Evolution) has been realized. In LTE, OFDM (Orthogonal Frequency Division Multiplexing: Orthogonal Frequency Division Multiplexing) and SC-FDMA (Single Carrier-Frequency Division Multiple Access: Single Carrier Frequency Division Multiple Access) are used as downlink and uplink wireless access technologies, respectively. It can perform high-speed wireless packet communication with a peak downlink transmission rate of over 100Mb / s and an uplink peak transmission rate of over 50Mb / s. The international standardization organization 3GPP (3rd Generation Partnership Project: 3rd Generation Partnership Project) has started r...
