Abstract

The objective of the present invention is to achieve appropriate communication in a next-generation communication system. A user terminal according to the present invention includes: a control unit which controls communications using a radio frame including a plurality of transmission time intervals (TTIs) capable of switching between a downlink and an uplink, and a prescribed TTI for DL transmission set at predetermined intervals; and a receiving unit which receives a synchronization signal and a notification signal in the prescribed TTI.

Claims (5)

1. A terminal comprising: a receiving section that receives at least one of synchronization signals and broadcast signals that are transmitted using given resources each formed of 5 consecutive or non-consecutive symbols; and a control section that controls reception of the at least one of the synchronization signals and the broadcast signals in a given transmission time interval in which the given resources are configured, wherein the control section is configured to be provided with resource 10 index information of the synchronization signals or the broadcast signals that are transmitted using the given resources in the given transmission time interval and to control reception of the synchronization signals or the broadcast signals based on the resource index information of the synchronization signals or the broadcast signals.
2. The terminal according to claim 1, wherein the control section controls a number of resources used for PRACH transmission based on a number of resources of the synchronization signals or the broadcast signals. 20
3. A radio communication method for a terminal, comprising: receiving at least one of synchronization signals and broadcast signals that are transmitted using given resources each formed of consecutive or non-consecutive symbols; and controlling reception of the at least one of the synchronization signals and 25 the broadcast signals in a given transmission time interval in which the given resources are configured, wherein the terminal is configured to be provided with resource index information of the synchronization signals or the broadcast signals that are transmitted using the given resources in the given transmission time interval and to control reception of the synchronization signals or the broadcast signals based 5 on the resource index information of the synchronization signals or the broadcast signals.
4. A base station comprising: a transmitting section that transmits at least one of synchronization signals 10 and broadcast signals using given resources, each formed of consecutive or non-consecutive symbols; and a control section that controls transmission of the at least one of the synchronization signals and the broadcast signals in a given transmission time interval in which the given resources are configured, 15 wherein the control section is configured to provide a terminal with resource index information of the synchronization signals or the broadcast signals that are transmitted using the given resources in the given transmission time interval and to control so that the terminal receives the synchronization signals or the broadcast signals based on the resource index information of the 20 synchronization signals or the broadcast signals.
5. A system comprising the terminal according to any of claims 1 to 2 and the base station according to claim 4.
