METHODS AND SYSTEMS FOR RESOURCE ALLOCATION
First Claim
Patent Images
1. A method comprising:
- in a time-frequency transmission resource comprising a plurality of transmission symbols, each on a plurality of sub-carriers;
creating one or more subzones of the time-frequency transmission resource wherein each subzone comprises at least one block of channel units comprising at least one sub-carrier used for all transmission symbols in the subzone;
scheduling at least one user in at least one of the one or more subzones;
controlling distribution of transmission power over the one or more subzones.

Abstract
Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

15. A method comprising:
-
in a time-frequency transmission resource comprising at least one subzone, each subzone comprising at least one partition, each partition having at least one resource block, each resource block having a plurality of transmission symbols on a plurality of sub-carriers, wherein one or more resource blocks are allocated to each of at least one user in a respective partition; for each partition, signalling a group of users with a group bitmap, wherein the group bitmap includes at least one bitfield that provides additional information about the one or more resource blocks allocated to the at least one user of the respective partition. - View Dependent Claims (16, 17, 19, 24, 26, 27, 28)

29. A method comprising:
in a two dimensional transmission resource, a first dimension being time and a second dimension being frequency; as a default setting, allocating resources for at least one user in the two dimensional transmission resource in one of the two dimensions first and the other dimension second. - View Dependent Claims (30, 31, 32, 33, 34, 35, 37, 38)

36. The method of method 35 wherein encoding the first packet with a second packet and transmitting the two packets on the persistently assigned resource further comprises at least one of:
-
increasing a size of the allocated resource for at least a first occurrence of the persistently assigned resource; and adjusting the modulation and coding scheme (MCS) and maintaining a consistent size for the allocated resource.

39. A method comprising:
in a two dimensional transmission resource, a first dimension being time and a second dimension being frequency, allocating a resource of a first size to at least one user in the two dimensional transmission resource and allocating a resource of a second size to at least one user in the two dimensional transmission resource. - View Dependent Claims (40)
