1. An apparatus, comprising: an integrated circuit configured for inclusion in a first mobile station, wherein the integrated circuit is configured to: receive first data from a base station using a downlink band of a cellular spectral resource;transmit second data to the base station using an uplink band of the cellular spectral resource;receive a message from the base station indicating resources allocated for direct transmissions between the first mobile station and at least one second mobile station; andbased at least in part on the received message from the base station, transmit information directly to the at least one second mobile station using the uplink band of the cellular spectral resource, wherein to transmit the information directly to the at least one second mobile station, the first mobile station is configured to reuse one or more transmission frequencies used in transmitting the second data to the base station. 2. The apparatus of claim 1, wherein the integrated circuit is further configured to: receive a configuration of a first portion of time for which direct mobile station to mobile station transmissions are enabled and a second portion of time for which mobile-base station communications are enabled. 3. The apparatus of claim 1, wherein the integrated circuit is further configured to determine synchronization at the first mobile station at least in part from a synchronization signal transmitted by at least one second mobile station. 4. The apparatus of claim 3, wherein the integrated circuit is further configured to determine frame timing information from the synchronization signal transmitted by the at least one second mobile station. 5. The apparatus of claim 1, wherein the integrated circuit is further configured to transmit to the at least one second mobile station, wherein at least the first mobile station is outside of base station coverage. 6. The apparatus of claim 1, wherein to transmit information directly to the at least one second mobile station, the first mobile station is further configured to: transmit a first direct transmission to the at least one second mobile station for direct communication establishment, wherein the first direct transmission is transmitted in a first set of defined resources, wherein the first set of resources are defined for first transmissions for direct communication establishment. 7. The apparatus of claim 6, wherein the first set of defined resources is indicated by the base station. 8. The apparatus of claim 1, wherein the integrated circuit comprises a microprocessor. 9. The apparatus of claim 1, wherein the integrated circuit comprises a field programmable gate array (FPGA). 10. An apparatus, comprising: an integrated circuit for inclusion in a first mobile station, wherein the integrated circuit is configured to: receive data from a base station using a downlink band of a cellular spectral resource;transmit data to the base station using an uplink band of the cellular spectral resource;receive a message from the base station indicating availability of direct communication between the first mobile station and a second mobile station; andin response to the message: receive data directly from the second mobile station; andtransmit data directly to the second mobile station. 11. The apparatus of claim 10, wherein the integrated circuit is further configured to receive data from the second mobile station using the uplink band of the cellular spectral resource. 12. The apparatus of claim 11, wherein the integrated circuit is further configured to transmit data to the second mobile station using the uplink band of the cellular spectral resource. 13. The apparatus of claim 10, wherein the integrated circuit is further configured to: in response to successful direct communication with the second mobile station, transmit a response to the message indicating successful direct communication with the second mobile station. 14. The apparatus of claim 10, wherein the integrated circuit is further configured to receive data from the base station and concurrently: transmit data to the second mobile station and/or receive data from the second mobile station. 15. The apparatus of claim 10, wherein the integrated circuit is further configured to: receive a configuration of a first portion of time for which direct mobile station to mobile station transmissions are enabled and a second portion of time for which mobile-base station communications are enabled. 16. The apparatus of claim 10, wherein the integrated circuit is further configured to determine synchronization at the first mobile station at least in part from a synchronization signal transmitted by the second mobile station. 17. The apparatus of claim 10, wherein at least the first mobile station is outside of base station coverage. 18. The apparatus of claim 10, wherein the integrated circuit comprises a microprocessor. 19. The apparatus of claim 10, wherein the integrated circuit comprises a field programmable gate array (FPGA).
