Abstract: A wireless communication device (12) served by a wireless wide area network (WWAN) base station supports per-bearer switching of bearer traffic between the WWAN and a wireless local area network (WLAN) in a manner transparent to the WLAN. The device in this regard establishes a secure tunnel (24) through the WLAN to a security gateway (22), based on the device receiving a message from the WWAN base station (18) to establish the secure tunnel (24). The device switches bearer traffic between the WWAN and the WLAN on a per bearer basis, with bearer traffic switched to the WLAN being transported through the secure tunnel (24) and over a connection (26) between the security gateway (22) and the WWAN base station (18).

Abstract: According to one aspect of the teachings herein, a base station (20) schedules the transmission of uplink reference signals by a wireless device (16) separately from scheduling uplink data transmissions by the device (16). The separate scheduling may be done at specific times, under specific conditions, and with respect to specific devices (16) or groups of devices (16). Separate scheduling allows, for example, the base station (20) to use smaller scheduling intervals that are possible when uplink reference signals are integrally included in any scheduled uplink data transmission. As a further advantage, the density or number of uplink reference signal transmissions by a given device (16) can be adapted, e.g., based on channel conditions, data transmission formats, etc.
