Abstract: Mechanisms are disclosed for improved transmission of uplink control information by a user equipment (UE) that is link budget limited. In one embodiment, the UE transmits a message to the base station indicating that the UE is link budget limited. In response to the message, the base station sends an uplink grant to the UE, enabling the UE to transmit uplink control information on the physical uplink shared channel (PUSCH) instead of on the Physical Uplink Control Channel (PUCCH). In another embodiment, the base station sends an uplink grant to a link-budget-limited UE each time downlink traffic is transmitted to the UE, enabling the UE to send ACK/NACK feedback on the PUSCH instead of the PUCCH. In another embodiment, the UE transmits a scheduling request (SR) to the base station as part of a random access procedure, enabling the SR to be transmitted on the PUSCH instead of the PUCCH.

Abstract: Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).

Abstract: A satellite system comprises LEO satellites and MEO satellites, and a control plane protocol architecture. The PHY, MAC, MAC/RLC and RRC layers are optimized for satellite environment. When the satellites are not processing satellites, eNB functions are implemented in a satellite gateway, and, when the satellites are processing satellites, protocol architecture in the control plane differ from LTE, as follows: PHY layer is moved to the communicating LEO/MEO satellite on the user link, MAC/RLC, RRC and PDCP are be located in satellite or gateway depending on satellite complexity, and the need to have mesh connectivity between UTs. When the RRC is implemented in the satellite, the RRC is divided into RRC-Lower and RRC-Upper layers. The RRC-L is satellite-based, and handles UT handover. The RRC-U is eNB-based, and handles resource management functions. The RRC-U communicates with the PDCP layer in the eNB to configure security, header and data compression.

The processor, in response to the received DRX information, controls the transceiver to monitor LTE-A physical downlink control channels (PDCCHs) in subframes in a first frequency band during an active time. The processor further, in response to detecting a downlink assignment in an LTE-A PDCCH in the first frequency band during the active time, wherein the downlink assignment indicates a second frequency band and assigned subcarriers within the second frequency band, to receive an LTE-A physical downlink shared channel (PDSCH) K subframes after a transmission of the downlink assignment. The second frequency band is different than the first frequency band.

Abstract: A method transmits data in a communications network containing a plurality of nodes. The transmission of suitable configuration data between a node and its neighboring node ensures that the time slots used for the data transmission are used only by one node, thus preventing collision. The method is preferably used in wireless sensor networks, in which the individual sensor nodes exchange data between one another. The method guarantees reliable data transmission with low energy consumption by the individual sensor nodes. The method can be combined with a decentralized pattern detection, for which mean values are decentrally determined in a suitable manner in the individual nodes via protocols known per se, particularly via a consensus protocol or via a tree aggregation protocol. The method is used particularly in a communications network for an automation system or a power network or a transport network.
