    摘要: Apparatus and methods for time division based communication between a wireless device and a wireless network in a licensed radio frequency (RF) band and an unlicensed RF band are disclosed. The wireless device receives downlink control information (DCI), via a primary component carrier (PCC) of a primary cell (Pcell) in the licensed RF band, indicating downlink (DL) data transmission via a secondary component carrier (SCC) of a secondary cell (Scell) in the unlicensed RF band. The wireless device receives via the SCC part of the DL data transmission and transmits a control message via the PCC in response. The wireless device sends a scheduling request (SR) to the eNodeB and receives uplink (UL) transmission opportunities in a combination of the licensed RF band and the unlicensed RF band. The wireless device performs a clear channel assessment before reserving and transmitting to the eNodeB in the unlicensed RF band.

    摘要: Apparatus and methods for estimating a location of a wireless device in communication with a wireless network, such as an LTE/LTE-A network, based at least in part on WLAN/WPAN AP measurements and/or barometric measurements are disclosed. The wireless device responds to a location capability inquiry from the wireless network by providing a response that indicates the wireless device is configurable to estimate its location based on WLAN/WPAN AP and/or barometric measurements. The wireless network sends WLAN/WPAN AP and/or barometric reference information to the wireless device to assist in estimating its location. The wireless device measures one or more WLAN/WPAN APs, and the wireless device uses the WLAN/WPAN AP and/or barometric measurements to estimate its location. In some embodiments, GPS/GNSS information is used in conjunction with WLAN/WPAN AP and/or barometric measurements to estimate the location of the wireless device.
