User terminal, radio base station and radio communication method

A radio communication method for a terminal comprising:

• receiving a system information block before a radio resource control connection;
• and
• determining one physical uplink control channel (PUCCH) resource set from a plurality of PUCCH resource sets based on an index within the system information block, and determining one PUCCH resource from a plurality of PUCCH resources within the PUCCH resource set based on a control channel element (CCE) index and a PUCCH resource indicator field within a downlink control information (DCI),
• wherein at least two of the plurality of PUCCH resources have different start physical resource block indices,
• wherein all of the plurality of PUCCH resources includes a same number of symbols and a same start symbol index, and at least two PUCCH resources out of the plurality of PUCCH resources include different initial cyclic shift indexes, and
• wherein a set of the initial cyclic shift indexes is different for each PUCCH format.

A base station comprising:

• a transmitter that transmits a system information block before a radio resource control connection;
• and
• a processor that controls reception of a physical uplink control channel (PUCCH) in a PUCCH resource,
• wherein one PUCCH resource set is determined from a plurality of PUCCH resource sets based on an index within the system information block,
• the PUCCH resource is determined from a plurality of PUCCH resources within the PUCCH resource set based on a control channel element (CCE) index and a PUCCH resource indicator field within a downlink control information (DCI),
• all of the plurality of PUCCH resources includes a same number of symbols and a same start symbol index,
• at least two of the plurality of PUCCH resources have different start physical resource block indices,
• at least two PUCCH resources out of the plurality of PUCCH resources include different initial cyclic shift indexes, and
• a set of the initial cyclic shift indexes is different for each PUCCH format.

A system comprising a terminal and a base station, wherein:

• the terminal comprises:
• a receiver that receives a system information block before establishing a radio resource control connection;
• and
• a processor that determines one physical uplink control channel (PUCCH) resource set from a plurality of PUCCH resource sets based on an index within the system information block, and determines one PUCCH resource from a plurality of PUCCH resources within the PUCCH resource set based on a control channel element (CCE) index and a PUCCH resource indicator field within a downlink control information (DCI), and
• the base station comprises:
• a transmitter that transits the system information block before the radio resource control connection,
• wherein at least two of the plurality of PUCCH resources have different start physical resource block indices,
• wherein all of the plurality of PUCCH resources includes a same number of symbols and a same start symbol index, and at least two PUCCH resources out of the plurality of PUCCH resources include different initial cyclic shift indexes, and
• wherein a set of the initial cyclic shift indexes is different for each PUCCH format.
