  • Patent number: 9312931
    Abstract: In a case where, although a radio base station (eNB 1-1) has established an SRS transmission frequency band, a serving radio terminal (UE 2-1) has transmitted, to the radio base station (eNB 1-1), an SRS by use of only a frequency band that is a part of the SRS transmission frequency band, the radio base station (eNB 1-1) allocates a downstream resource block the frequency band of which is included in the SRS transmission frequency band and further the frequency band of which is identical with the frequency band of the SRS received at the latest; then establishes, for the downstream resource block, a transmission weight based on the SRS received at the latest; and then uses the downstream resource block to transmit a radio signal.

  • Patent number: 9301194
    Abstract: An eNB1-1 transmits an RRC Connection Reconfiguration message to UE2-1 to UE2-3, in which SRS parameters and an application timing parameter are set, the SRS parameters differ for each of the UE2-1 to the UE2-3 and the application timing parameter is common in the UE2-1 to the UE2-3. The UE2-1 to the UE2-3 receive the RRC Connection Reconfiguration message and recognize the SRS parameters and the application timing parameter set in the message. Furthermore, when an application timing of the SRS parameter arrives, the UE2-1 to the UE2-3 apply the SRS parameter to the SRS and transmit the SRS.

  • Patent number: 9119194
    Abstract: A base station (12) performs communication to and from a mobile station via at least a part of a plurality of radio channels. The base station (12) includes: a channel allocation section (30) for allocating a radio channel having an allocation effective period of two or more frames to the mobile station; and a channel notification section (34) for notifying the mobile station of a radio channel newly allocated by the channel allocation section (30) in response to an expiration of the allocation effective period of the radio channel which has been allocated by the channel allocation section (30). The mobile station uses the radio channel notified from the base station (12) for communicating to and from the base station (12) until an allocation effective period of the new radio channel expires.
