  • Publication number: 20180070244
    Abstract: Embodiments of the present invention disclose a method for detecting a signal on an unlicensed spectrum channel, user equipment, and a base station. The method includes: receiving, by user equipment, instruction information sent by a base station; and starting, by the user equipment according to the instruction information, to detect a signal on an unlicensed spectrum channel. According to the present invention, only when receiving the instruction information sent by the base station, the user equipment detects the signal on the unlicensed spectrum channel according to the instruction information. This reduces power consumption of the user equipment.

  • Publication number: 20170142751
    Abstract: A system and method of subframe configuration in licensed-assisted access using long-term evolution (LAA-LTE) with carrier aggregation (CA). A wireless device such as an eNodeB (eNB) may transmit control information in a subframe from a secondary cell (SCell) in downlink control information (DCI) to a user equipment (UE). The SCell may operate in an unlicensed band. The control information may indicate at least one of a non-ending subframe in a data burst, an ending subframe, and a duration of the ending subframe. The duration may be one of a predefined number of orthogonal frequency-division multiplexing (OFDM) symbol durations, and the ending subframe may be a partial or full subframe. A partial ending subframe may use a time slot structure in a time division duplexing (TDD) scheme, e.g., downlink pilot time slots (DwPTS). The eNB may then transmit to the UE data in the subframe according to the control information.
