Broadcast signal indicating one or more subframe configurations

Abstract

A mobile station may comprise a receiver to receive, from a base station, a broadcast signal indicating a TDD configuration of uplink OFDM symbols and downlink OFDM symbols. The receiver may receive an indication of a symbol range and a subchannel range for use in transmission of CQI feedback. The mobile station may receive first downlink data and transmit first uplink data, using the TDD configuration, wherein the first uplink data comprises CQI feedback information transmitted in accordance with the symbol range and the subchannel range. The receiver may receive second downlink data, from the base station, on a different frequency as the first uplink data is transmitted, while the first uplink data is transmitted.

We claim: 
     
         1 . A method, comprising:
 generating, by a wireless device, one or more frames, each frame comprising at least one video subframe or at least one data subframe; and   transmitting, by the wireless device to at least one other wireless device in a wireless communication network, the one or more generated frames;   wherein the at least one video subframe utilizes a downlink broadcast channel established between the wireless device and the at least one other wireless device, and   wherein the at least one data subframe utilizes a downlink unicast channel established between the wireless device and a first other wireless device of the at least one other wireless device.   
     
     
         2 . The method of  claim 1 , wherein the downlink broadcast channel is transmitted via a first frequency band, and wherein the downlink unicast channel is transmitted via a second frequency band different from the first frequency band. 
     
     
         3 . The method of  claim 2 , wherein a first frame comprises a first video subframe and a first data subframe, and wherein the first video subframe is transmitted at a first time and the first data subframe is transmitted at the first time. 
     
     
         4 . The method of  claim 1 , wherein the downlink broadcast channel and the downlink unicast channel are transmitted via the same frequency band. 
     
     
         5 . The method of  claim 4 , wherein a first frame comprises a first video subframe and a first data subframe, and wherein the first data subframe is transmitted at a first time and the first video subframe is transmitted at a second time different from the first time. 
     
     
         6 . The method of  claim 4 , wherein a first frame comprises a first data subframe, wherein a second frame comprises a first video subframe, and wherein the first data subframe is transmitted at a first time and the first video subframe is transmitted at a second time different from the first time. 
     
     
         7 . The method of  claim 6 , wherein the first data subframe comprises an identification of the second time at which the first video subframe is transmitted. 
     
     
         8 . The method of  claim 7 , wherein receipt of the first data subframe causes the first other wireless device to enter a low power mode until the second time. 
     
     
         9 . The method of  claim 1 , wherein generating the one or more frames further comprises inserting a sequence number of a first video subframe in a first data subframe. 
     
     
         10 . The method of  claim 1 , wherein each frame comprises a header identifying a configuration of subframes of the frame. 
     
     
         11 . A device, comprising:
 a processor configured to generate one or more frames, each frame comprising at least one video subframe or at least one data subframe; and   a transmitter, configured to transmit to at least one other device in a wireless communication network, the one or more generated frames;   wherein the at least one video subframe utilizes a downlink broadcast channel established between the device and the at least one other device, and   wherein the at least one data subframe utilizes a downlink unicast channel established between the device and a first other device of the at least one other device.   
     
     
         12 . The system of  claim 11 , wherein the downlink broadcast channel is transmitted via a first frequency band, and wherein the downlink unicast channel is transmitted via a second frequency band different from the first frequency band. 
     
     
         13 . The system of  claim 12 , wherein a first frame comprises a first video subframe and a first data subframe, and wherein the first video subframe is transmitted at a first time and the first data subframe is transmitted at the first time. 
     
     
         14 . The system of  claim 11 , wherein the downlink broadcast channel and the downlink unicast channel are transmitted via the same frequency band. 
     
     
         15 . The system of  claim 14 , wherein a first frame comprises a first video subframe and a first data subframe, and wherein the first data subframe is transmitted at a first time and the first video subframe is transmitted at a second time different from the first time. 
     
     
         16 . The system of  claim 14 , wherein a first frame comprises a first data subframe, wherein a second frame comprises a first video subframe, and wherein the first data subframe is transmitted at a first time and the first video subframe is transmitted at a second time different from the first time. 
     
     
         17 . The system of  claim 16 , wherein the first data subframe comprises an identification of the second time at which the first video subframe is transmitted. 
     
     
         18 . The system of  claim 17 , wherein receipt of the first data subframe causes the first other device to enter a low power mode until the second time. 
     
     
         19 . The system of  claim 11 , wherein the processor is further configured to insert a sequence number of a first video subframe in a first data subframe. 
     
     
         20 . The system of  claim 11 , wherein each frame comprises a header identifying a configuration of subframes of the frame.
