Method and apparatus for a scheduler for a macro-diversity portion of a transmission
First Claim
1. A method of transmitting content data in a macro-diversity region of a data frame, the method comprising:
- receiving a stream of transport packets;
selecting a burst size from a plurality of predetermined burst sizes;
allocating a data burst having the selected burst size to the macro-diversity region of the data frame, wherein the data burst includes at least a portion of the received stream of transport packets, and wherein the burst size is selected such that a number of data bursts allocated to the macro-diversity region is minimized;
communicating information to a base station for transmitting a first signal including the data frame from a first transmitter, wherein the information indicates the allocation of the data burst to the macro-diversity region.

Abstract
A method, apparatuses, and system of broadcasting content data in a macro-diversity region of a data frame includes receiving a stream of transport packets. Selecting at least one burst size, from amongst a set of a plurality of predetermined burst sizes. Allocating one or more data bursts with the selected burst size to the macro-diversity region of the data frame, each data burst comprising at least a portion of the received transport packets and wherein the at least one burst size is selected so as to minimize a number of data bursts allocated to the macro-diversity region. Then communicating the allocation of data bursts to a transmitter that includes the allocation of data bursts in the macro-diversity region of a data frame transmitted by the transmitter.

10. A method of transmitting a macro-diversity region in an OFDMA system, the method comprising:
-
identifying a plurality of sub-channels; assigning a plurality of symbols to the plurality of sub-channels, wherein each symbol of the plurality of symbols is assigned to a different one of the plurality of sub-channels during a symbol period; identifying a plurality of sub-channels and a plurality of symbol periods, wherein a symbol period comprises a plurality of symbols, and wherein during the symbol period each symbol of the plurality of symbols is associated with a different one of the plurality of sub-channels; generating a first map, wherein the first map includes information that describes a data burst and a size of a second map, and wherein the second map is transmitted in a subsequent macro-diversity region; transmitting the map from a transmitter via a first sub-channel during the symbol period; and transmitting the data burst from the transmitter via a second sub-channel during the symbol period. - View Dependent Claims (11, 12, 13)

14. A method of transmitting content data in a macro-diversity region of a data frame, the method comprising:
-
encapsulating a plurality of transport packets, wherein the plurality of transport packets includes content data; selecting a burst size from a plurality of predetermined burst sizes; and allocating a data burst having the selected burst size to the macro-diversity region of the data frame, wherein the data burst includes at least a portion of the encapsulated plurality of transport packets, and wherein the burst size is selected such that a number of data bursts allocated to the macro-diversity region is minimized; and transmitting from a first and a second transmitter a signal including the data frame, such that the signals transmitted from the first and second transmitter are synchronized. - View Dependent Claims (15)

19. A scheduler comprising:
-
an input configured to receives a plurality of data packets; a processor configured to; select a burst size from a plurality of predetermined burst sizes such that the selected burst size is the largest burst size of the plurality of predetermined burst sizes that fits within a non-allocated portion of a macro-diversity region of a data frame; allocate a data burst having the selected burst size to the macro-diversity region of the data frame; update a size of the non-allocated portion of the macro-diversity region based on the size of the allocated burst; and on a condition that the size of the remaining portion available in the macro-diversity region is equal to or larger than a smallest burst size of the plurality of predetermined burst sizes, repeats the selecting, allocating, and updating; and an output configured to communicate the allocation of data bursts to a base station. - View Dependent Claims (20, 21, 22, 23, 24, 25)
