摘要： Provided is a radio communication base station device which can suppress a use amount of an SRS communication resource. In this device, a correlation rule setting unit (102) sets a rule for correlating a preamble with an SRS transmission time interval so that the preamble transmission time band and the SRS transmission time band are in the same transmission time band. An SRS transmission band decision unit (103) decides a time interval of a transmission time band which can transmit the SRS according to the preamble transmission time interval inputted from a preamble transmission band decision unit (101) and the correlation rule setting unit (102).

摘要： Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.

摘要： A mobile station includes communication control circuitry that selects a preamble contained in a first Random Access Preamble group when a message size based on data available for transmission does not meet a first condition or when a value calculated based on a reference signal received power of downlink does not meet a second condition, a preamble contained in a second Random Access Preamble group when the message size based on data available for transmission meets the first condition and the value calculated based on the reference signal received power of downlink meets the second condition, and a preamble contained in the third Random Access Preamble group for a handover, independent of the message size based on data available for transmission and the value calculated based on the reference signal received power of downlink. The communication control circuitry also generates and transmits a selected preamble.

摘要： A base station is provided, including a transmitter configured to broadcast information for determining one or more first preambles contained in a first Random Access Preamble group and any second preamble(s) contained in a second Random Access Preamble group; and a receiver configured to receive a preamble transmitted by a mobile station. The received preamble is randomly selected from among the first preamble(s) when the first Random Access Preamble group is selected, or is randomly selected from among the second preamble(s) when the second Random Access Preamble group is selected. The second Random Access Preamble group is selected if a message size based on data available for transmission by the mobile station meets a first condition and if a value calculated based on a reference signal received power of downlink meets a second condition, and else the first Random Access Preamble group is selected.
