Patent ID: 8681749

Claim:
An apparatus for wireless communication, comprising: a processor; and a memory coupled to the processor, wherein the memory stores instructions executable by the processor to perform operations comprising: receiving a control resource index R of a control resource; calculating a tile index h and a transmission unit index r based on the control resource index R; mapping the control resource to a transmission unit with the transmission unit index r in a tile with the tile index h, wherein the transmission unit corresponds to a particular hop-port, wherein the control resource is one of a plurality of control resources of a control segment, wherein the plurality of control resources includes a first control resource and a second control resource, wherein the control segment comprises L tiles, wherein L is a positive integer, and wherein each of the tiles comprises a plurality of transmission units that includes a first transmission unit and a second transmission unit; allocating the first control resource to a first control channel by mapping, according to a localized mapping scheme, the first control resource to the first transmission unit; and allocating the second control resource to a second control channel by mapping, according to a mapping scheme other than the localized mapping scheme, the second control resource to the second transmission unit, wherein the first control resource is allocated to the first control channel prior to the second control resource being allocated to the second control channel.
