Abstract
A communication configuration is selected based on the bandwidth used by a wireless communication device during a random access procedure (e.g., on an unlicensed band). In some scenarios, the maximum transmit power that the wireless communication device can use may be significantly restricted (e.g., by a regulation). In some cases (e.g., when the wireless communication device is near a center of a cell), the wireless communication device may transmit the random access information using a default bandwidth. In other cases (e.g., when the wireless communication device is near a cell edge), the wireless communication device may transmit the random access information using a wider bandwidth (e.g., to increase the coverage of the transmission). In some aspects, the maximum bandwidth used for the random access procedure may be used to select at least one communication configuration that is used for a subsequent communication (e.g., data or control signaling).
