A portable sensor device incorporates a low-power, nanostructure sensor coupled to a wireless transmitter. The sensor uses a nanostructure conducting channel, such as a nanotube network, that is functionalized to respond to a selected analyte. A measurement circuit connected to the sensor determines a change in the electrical characteristic of the sensor, from which information concerning the present or absence of the analyte may be determined. The portable sensor device may include a portable power source, such as a battery. It may further include a transmitter for wirelessly transmitting data to a base station.

RLC processing section 106 supplies packet data requested for retransmission from a mobile terminal and new packet data not requested for retransmission to buffer 107 corresponding to data amounts controlled in HS-DSCH/FP processing section 108. Buffer 107 temporarily stores the packet data requested for retransmission and the new packet data not requested for retransmission to output at predetermined timing. HS-DSCH/FP processing section 108 detects a receivable data amount of the mobile terminal using CQI, and controls RLC processing section 106 so that the amount of data stored of packet data in buffer 107 does not exceed the receivable data amount of the mobile terminal. It is thereby possible to decrease the number of retransmissions to improve the throughput, and prevent suspension of the communication and disconnection of the channel.

Methods, systems, and devices are described for wireless communication at a device. A wireless device may be configured with a transmission time interval (TTI) bundling parameter. The device may then identify one or more resources for an uplink (UL) control channel based on the TTI bundling parameter (e.g., using either an implicit or an explicit indication from another wireless node such as a serving cell of a base station) and transmit the UL control channel using the identified resources. The device may also identify a downlink control information (DCI) format based on the TTI bundling parameter. For example, a resource allocation granularity level may be associated with the bundling parameter, and the length of a DCI field may depend on the resource allocation granularity level.
