Abstract:
1. A method of packing an orthogonal frequency division multiple access/time division multiple access (OFDMA/TDMA) frame comprising sub carriers grouped into sub channels and time slots containing OFDM symbols, wherein the OFDMA/TDMA frame is modeled as a matrix with rows corresponding to the sub channels and columns corresponding to the OFDM symbols, comprising: creating the matrix having a same number of rows and columns as the OFDMA/TDMA frame; mapping a first control message to a position in a first corner of the matrix; mapping a first data message to a position in a second corner of the matrix, wherein the second corner is at an opposite end of a row of the matrix in a predetermined direction from the first corner; mapping, by a base station device, a plurality of further control messages to the matrix in a first direction moving away from the first corner downward in a first column associated with the first corner until the first column is filled and then to a next available column closer to the second corner; mapping, by the base station device, a plurality of further data messages to the matrix in a second direction that is different from the first direction, away from the second corner of the matrix downward in a second column associated with the second corner until the second column is filled and then to another available column closer to the first corner; until one or more of the further data messages meets one or more of the further control messages; providing the control messages from the matrix so that the first control message is located at the start of the OFDMA/TDMA frame; and providing the data messages from the matrix so that the first data message is located directly after the control messages in the OFDMA/TDMA frame.
