摘要： Communication systems may benefit from a control channel for contention based transmission and collision avoidance. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) and LTE-Advanced may use such control channels for contention based transmission. In particular, such control channels may be valuable with respect to LTE-based local area network (LTE-LAN). A method, according to certain embodiments, may include preparing control information for a contention based physical uplink shared channel. The method may also include transmitting and/or receiving the control information on a physical uplink control channel and a control only physical uplink shared channel, or only on the control only physical uplink shared channel.

摘要： A macro eNB (MeNB) triggers a small cell (eLA eNB) to transmit a sequence on a second frequency band using a triggering command that indicates a time to transmit the sequence. On a first frequency band the MeNB triggers at least one user equipment UE to detect the sequence on the second band, and this trigger also has a first indication of when the sequence will be transmitted. From a second indication the MeNB receives on the first band from the at least one UE in response to the triggering of the UE the MeNB can determine whether the UE is located proximate to the small cell. The indication may be as little as a single bit indicating whether the UE detected or not the sequence. The first and second bands may be on first and second component carriers that may not be synchronized to one another, and the aperiodic nature of the triggered sequences and detection reports saves UE power.

摘要： Provided are methods, corresponding apparatuses, and computer program products for performing out-of-band sensing on an unlicensed frequency band. A method comprises sending a configuration message for configuring measurement on at least one channel in a frequency band of a primary system; receiving a measurement report made based upon the configuration message; and determining the usability of the at least one channel based upon the measurement report, wherein the configuration message includes information regarding a respective predetermined threshold of energy detection or primary-system-feature detection, and the measurement report is for reception when a measured energy detection value or a measured primary-system-feature detection value of a received signal on the at least one channel is less than the respective predetermined threshold. With the claimed inventions, the spectrum efficiency would be improved and interference between a secondary system and an LTE system could be alleviated.

摘要： Provided are methods, corresponding apparatuses, and computer program products for performing spectrum sensing on a spectrum. A method comprises receiving, at a user equipment, information regarding performing spectrum sensing from a base station; performing, based upon the information, the spectrum sensing by the user equipment in an idle mode; and transmitting, by the user equipment out of the idle mode, to the base station a result of the spectrum sensing. With the claimed inventions, transmission interruption caused by non-idle user equipments performing the spectrum sensing would be eliminated.
