20150163221 | SYSTEM AND METHOD FOR ALLOWING ACCESS TO ELECTRONIC DEVICES USING A BODY AREA NETWORK - A method, system and devices for creating access to a wireless communication device by using BAN, comprising detecting the presence of a user's body by using a BAN enabled access module connected to the wireless communication device, collecting biometric data of the user and receiving authentication data from a BAN enabled peripheral device through BAN by using the BAN enabled access module and allowing access to the wireless communication device if the collected biometric data and the received authentication data are valid. | 06-11-2015 |
20150295304 | DEVICE WITH RADIO AND BODY-COUPLED-COMMUNICATION CONNECTIVITY - A device is equipped with one or more communication modules supporting communication on the basis of radio signals and communication on the basis of body-coupled communication signals. Further, the device is equipped with an antenna for transmission of the radio signals. The antenna is further operable to transfer the body-coupled communication signals between the device and a body of a user of the device. | 10-15-2015 |
20150349856 | METHOD OF CONTROLLING A SIGNAL TRANSMISSION IN A CELLULAR MIMO SYSTEM, BASE STATION, AND CELLULAR MIMO SYSTEM - A cellular multiple-input and multiple-output (MIMO) system has a base station. The base station has a plurality of antennas. To control a signal transmission in the MIMO system, the base station monitors at least one indicator which indicates whether a spatial resolution of the plurality of antennas allows signals received from at least two terminals to be distinguished. The base station selectively activates a multiple access transmission and reception for the at least two terminals as a function of the at least one indicator. The multiple access transmission and reception causes the at least two terminals to share a common channel. | 12-03-2015 |
20150351047 | POWER EFFICIENT CONTROL OF UPLINK CARRIER USAGE BY MOBILE TERMINAL - In data transmission between a mobile terminal and a cellular network, a network component, e.g., a base station, establishes a downlink connection from the cellular network to the mobile terminal. The downlink connection uses one or more downlink carriers. Further, the network component identifies multiple uplink carriers which are available for establishing an uplink connection from the mobile terminal to the cellular network. The network component estimates impact of usage of the uplink carriers on power consumption of the mobile terminal. Depending on the estimated impact, the network component selects at least one of the uplink carriers for establishing the uplink connection. | 12-03-2015 |
20150365982 | MASSIVE MIMO LINK SETUP - The invention is directed to establishing a massive multiple-input multiple-output (MIMO) link between an access point (AP) and a user equipment (UE). An exemplary method comprises: first repeatedly transmitting pilots from the UE to the AP for a first duration, wherein the first duration covers a portion of a data frame; listening at the UE for a response from the AP for substantially the first duration; in response to not receiving a response from the AP, second repeatedly transmitting pilots from the UE to the AP for a second duration, wherein the second duration covers at least a portion of the remaining portion of the data frame not covered during the first duration; and receiving an acknowledgment at the UE from the AP, and establishing the massive MIMO link between the UE and AP. | 12-17-2015 |
