Abstract: Apparatus and methods for estimating a location of a wireless device in communication with a wireless network, such as a UMTS 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.

Abstract: This disclosure relates to temporary suspension, and subsequent resumption, of radio resource aggregation in a wireless communication system. A wireless device may establish a communication link with a base station. The communication link with the base station may aggregate radio resources according to a first wireless communication technology and a second wireless communication technology. Use by the communication link of radio resources according to the second wireless communication technology may be suspended. Wireless communication activity according to the second wireless communication technology that is not associated with the communication link may be performed while use by the communication link of radio resources according to the second wireless communication technology is suspended. Use by the communication link of radio resources according to the second wireless communication technology may be resumed after performing the wireless communication activity according to the second wireless communication technology.

Abstract: This disclosure relates to using a dedicated reference subframes in a cellular communication system. According to one embodiment, a base station may transmit reference signals in a dedicated synchronization and measurement reference subframe. Neighboring base stations may also transmit reference signals in dedicated reference subframes in a temporally coordinated (synchronized) manner. The reference signals transmitted be each base station may be orthogonal with the reference signals transmitted by each neighboring base station. The reference subframes may be transmitted periodically, and data subframes may be transmitted between reference subframes. Some or all of the data subframes may not include cell-specific reference symbols, as their function may be unnecessary given the use of the dedicated reference subframes.
