Abstract: This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value.

Abstract: A more efficient network can be achieved using channel allocation strategies within a wireless network. A network device can receive several data points from a mobile device including resource request data, access condition data, and location data. Once the network device has received the aforementioned data points, the network device can identify channels that are conducive to a heightened quality of service for a resource being requested based on a signal attenuation associated with the channel. The network device can then facilitate a channel selection in response to an assessment of the data points and identifying a channel for the resource.
