20130010830 | RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD - A BT apparatus unit configured to perform Bluetooth (registered trademark) communication, a WLAN apparatus unit configured to perform WLAN communication, and an information managing unit configured to acquire a WLAN communication frequency band, which is a frequency band used for the WLAN communication, from the WLAN apparatus unit, determine an unusable frequency band based on the acquired WLAN communication frequency band, and notify the BT apparatus unit of the determined unusable frequency band. The BT apparatus unit performs frequency hopping using a frequency band excluding the unusable frequency band. | 2013-01-10 |
20130010831 | Wireless Communications Apparatus - MIMO UWB Communications apparatus is configured to send out a channel estimation sequence comprising a plurality of sequentially transmitted symbols in accordance with a first band hopping sequence, sent from one antenna of the apparatus, while another antenna is transmitting another sequence of channel estimation symbols in accordance with another, complementary band hopping sequence. A legacy device will be capable of synchronising with the channel estimation symbols sent in accordance with the first band hopping sequence, while a MIMO receiver will be able to determine channel estimates for all MIMO channels on the basis of the combined channel estimation transmissions. | 2013-01-10 |
20130010832 | METHOD AND APPARATUS FOR FREQUENCY ASSIGNMENT IN A FREQUENCY HOPPING MODE OF A WIRELESS COMMUNICATION SYSTEM - A frequency allocation method and apparatus using a mirroring-assisted frequency hopping pattern is provided for retransmission in a wireless communication system operating in a frequency hopping mode. A frequency mapping method for a wireless communication system operating in a frequency hopping mode includes determining whether or not mirroring is used in accordance with a number of packet transmissions; mapping a frequency resource for a packet transmission based on a result of the determination; and receiving a packet using the mapped frequency resource. | 2013-01-10 |
