A radio communication apparatus includes a communicator, and a controller configured to perform, in a case where search auxiliary information used to search for a base station used as a connection destination is stored, a first base station search based on the search auxiliary information. The controller is configured to perform a second base station search on all frequencies supported by the communicator in a case of failure in the first base station search or in a case where the search auxiliary information is not stored. The controller is configured to determine whether to store base station information related to the base station used as a connection destination, as the search auxiliary information, based on a movement state of the radio communication apparatus when location registration is performed via the base station used as the connection destination.

Radio communication apparatus and method

A communication equipment for which an extended DRX is available negotiates with a management apparatus included in a network to acquire a configuration parameter of the extended DRX. The communication equipment checks whether the base station is for which the extended DRX is available based on notification information received from the base station. The communication equipment notifies the external equipment of an operation state indicating whether the communication equipment is performing an extended DRX operation based on whether a configuration parameter of the extended DRX is acquired and whether the base station is for which the extended DRX is available.

Communication equipment, control method, program, and communication system

A roadside unit comprises a communication unit and a controller. The communication unit wirelessly communicates with a vehicle. The controller: (i) obtains size information indicating a size of the vehicle; (ii) determines, based on the size information, whether the size is larger than a reference value; and (iii) transmits predetermined information to the vehicle through the communication unit when determining that the size is larger than the reference value.

Roadside unit and vehicle

The press-through pack package of the invention has a covering material composed of a stretched film with at least one layer comprising a thermoplastic resin and an inorganic filler at 5 parts by weight with respect to 100 parts by weight of the thermoplastic resin.

An eNB-employs frequency hopping that assigns a radio resource to a UE-in response to switching of a frequency of an SRS from the UE-, and determines an MCS in a first radio resource block when a first downlink radio resource block is assigned to the UE-, on the basis of SINR acquired for a second downlink radio resource block having a frequency bandwidth equal to a frequency bandwidth of the first downlink radio resource and being assigned to the UE-in the past.

Radio base station and communication control method

In a case where, although a radio base station (eNB-) has established an SRS transmission frequency band, a serving radio terminal (UE-) has transmitted, to the radio base station (eNB-), an SRS by use of only a frequency band that is a part of the SRS transmission frequency band, the radio base station (eNB-) 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.

Radio base station, radio terminal, and communication control method

An eNB-transmits an RRC Connection Reconfiguration message to UE-to UE-, in which SRS parameters and an application timing parameter are set, the SRS parameters differ for each of the UE-to the UE-and the application timing parameter is common in the UE-to the UE-. The UE-to the UE-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 UE-to the UE-apply the SRS parameter to the SRS and transmit the SRS.

Radio base station, radio terminal, and communication control method for applying a reference signal parameter

If the frequency band of an SRS from a serving radio terminal (UE-) is identical with the frequency band of an SRS from a serving radio terminal (UE-), a radio base station (eNB-) transmits, to one of the serving radio terminals (UE-, UE-), an RRC connection reconfiguration message in which transmission halt request information has been set.

Radio base station and communication control method including a request to stop transmission of a reference signal at a predetermined timing

A wireless base station (eNB-) uses in a differentiated manner, depending on the expected data amount of downlink transmission to the serving wireless terminal UE, the transmission of RRC Connection Reconfiguration messages in which SRS specific transmission request information is set, and the transmission of RRC Connection Reconfiguration messages in which SRS hopping transmission request information is set.

Sounding reference signal to determine antenna weight and frequency bands

The present invention provides a wireless base station (eNB-) that sets a first SRS transmission frequency band as a transmission frequency band for SRS at a first SSF timing and sets the first SRS transmission frequency band as the transmission frequency band for SRS at a second SSF timing, within the time for one frame. In this way, all frequency bands (allocatable frequency bands) for usable downstream resource blocks in wireless communications between the wireless base station (eNB-) and a serving wireless terminal (UE-) are covered by the first SRS transmission frequency band and the second SRS transmission frequency band.

Radio base station and communication control method setting an entire frequency band of a radio resource as a reference signal transmission frequency band within a predetermined period

Disclosed is a wireless base station (eNB-) that sets to each serving wireless terminal (UE) different frequency bandwidths (SRS transmission frequency bandwidths) that are used when said serving wireless terminals (UE) send SRS at a predetermined special sub-frame timing. In addition the wireless base station (eNB-) sends the set SRS transmission frequency bandwidth information to the serving wireless terminals (UE).

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

A transmission path state estimation unit estimates a state of a transmission path to a wireless terminal based on a DRS (Demodulation Reference Signal) included in uplink user data received from the wireless terminal when a re-sending request is received after transmission of an SRS is stopped. A transmission unit forms directivity of a plurality of antennas based on the estimated state of the transmission path and transmits downlink user data.

Wireless base station and wireless communication method

A resource determination unit determines at least a part of an uplink part in a switch subframe as a second resource for a wireless terminal to transmit an SRS and determines at least a part within any uplink subframe as a third resource for the wireless terminal to transmit uplink user data including a DRS for a prescribed period. A transmission path state estimation unit estimates a state of a transmission path to the wireless terminal based on the DRS included in the uplink user data after the third resource is determined. A resource notification unit forms antenna directivity based on the estimated state of the transmission path and transmits a control message for notifying the wireless terminal of the determined second resource.
