Abstract: The present disclosure relates to component carrier (CC) selection in a wireless communication system. A user equipment (UE) that is in idle mode may receive a reference signal (RS) from an evolved Node B (eNB), obtain signal quality measurements with respect to the RS, and switch to a new CC based on the signal quality measurements. For a UE that is in connected mode, an eNB may obtain uplink channel condition information corresponding to uplink CCs, obtain downlink channel condition information corresponding to downlink CCs, and select a CC pair for the UE to use based on the uplink channel condition information and the downlink channel condition information.

Abstract: A method performed by a user equipment (UE) is described. The method includes receiving a physical cell identifier information element (IE) from an evolved node B (eNB). The physical cell identifier IE is associated with a secondary cell (SCell) that is on an unlicensed Long-Term Evolution (LTE) carrier frequency. The method also includes determining a physical-layer cell identity (PCI) of the SCell based on the physical cell identifier IE. The method further includes applying the PCI as a parameter for physical channels or signals on the SCell.

Abstract: A wireless terminal device (30) is capable of operating both in a licensed radio frequency band and an unlicensed radio frequency band. The wireless terminal device (30) comprises processor circuitry (40) configured (1) to select a first requirement comprising at least a first rule governing utilization of the unlicensed radio frequency band and (2) to use a second requirement comprising at least a second rule for implementing the first rule of the selected first requirement. The first requirement may be a regional requirement and the second requirement may be an operator requirement.

Abstract: Methods, systems, and devices provide improved power control for signals used for device-to-device services. In one aspect, a user equipment (“UE”) terminal controls the transmission power of signals used for device-to-device (“D2D”) services based on power control parameters provided by a base station. The UE terminal includes a first power control module for controlling a first transmission power to be applied to signals used for communication with a base station. The UE terminal also includes a second power control module for controlling a second transmission power to be applied to signals used for D2D services. The first and second transmission powers can be determined based on at least one power control parameter received from the base station. The UE terminal also includes a signal transceiver module for transmitting signals used for uplink/downlink communications using the first transmission power and transmitting signals used for D2D services using the second transmission power.

Abstract: A method for determining whether to attempt to attach to a network by a machine type communication (MTC) device is described. A triggering event is detected. A radio frame is received from a base station. The radio frame includes a current access class of the base station. The radio frame is the first radio frame to include the current access class after the triggering event. It is determined if the MTC device has access privileges to the base station. It is then decided whether to attempt to attach to a network based on if the MTC device has access privileges.

Abstract: A method for self-configuration of offset factors between two base stations in a wireless communications system is described. A first offset factor is sent to a first user equipment (UE) by a first base station. An offset factor is an indication of the reselection area around a home evolved nodeB (HeNB). A second offset factor is received from a second UE. The first offset factor is modified using the second offset factor. The modified first offset factor is sent to the first UE.

Abstract: A user equipment (UE) that supports multiple antenna transmission via multiple power amplifiers may operate in a reduced power amplifier (PA) mode. When operating in the reduced PA mode, a subset of the UE's power amplifiers are used to transmit uplink signals. A UE may send a preference signal to an e-Node B to request that the UE operate in the reduced PA mode.

Abstract: The present disclosure relates to determining whether system information can be reused and managing system information in a wireless communication system. A wireless communication device may read and compare a physical cell identity and specific system information of a target component carrier with the physical cell identity and specific system information of a source component carrier to determine whether generic system information needs to be read or can be reused. A base station may determine whether a change in system information impacts generic system information and specific system information. The base station may update a data control variable such that it is synchronized for particular sets of component carriers.
