Apparatus, methods, and computer program products providing a dynamic header structure for signaling resource allocations

A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, said operations comprising:

• receiving a message comprising a resource allocation map, wherein the resource allocation map comprises a first portion and a second portion, wherein the first portion is indicative of a first mapping scheme or a second mapping scheme, wherein the indicated first mapping scheme or second mapping scheme is applicable to the second portion, wherein under the first mapping scheme the second portion consists of resource allocation information that indicates at least one group of physical resource blocks that is allocated to the apparatus, wherein under the second mapping scheme the second portion comprises a third portion and a fourth portion, wherein the third portion is indicative of at least one aspect relating to the fourth portion, wherein the fourth portion comprises resource allocation information for resource blocks that are allocated to the apparatus;
• utilizing the first portion to determine the indicated mapping scheme to be used for the second portion;
• and
• obtaining, based on the determined mapping scheme, the resource allocation information from the second portion.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program instructions, the at least one memory and the computer program instructions being configured to, with the at least one processor, cause the apparatus at least to perform:
• receive a message comprising a resource allocation map, wherein the resource allocation map comprises a first portion and a second portion, wherein the first portion is indicative of a first mapping scheme or a second mapping scheme, wherein the indicated first mapping scheme or second mapping scheme is applicable to the second portion, wherein under the first mapping scheme the second portion consists of resource allocation information that indicates at least one group of physical resource blocks that is allocated to the apparatus, wherein under the second mapping scheme the second portion comprises a third portion and a fourth portion, wherein the third portion is indicative of at least one aspect relating to the fourth portion, wherein the fourth portion comprises resource allocation information for resource blocks that are allocated to the apparatus;
• utilize the first portion of the received message to determine the indicated mapping scheme to be used for the second portion, and
• obtain, based on the determined mapping scheme, the resource allocation information from the second portion.

An apparatus comprising:

• means for receiving a message comprising a resource allocation map, wherein the resource allocation map comprises a first portion and a second portion, wherein the first portion is indicative of a first mapping scheme or a second mapping scheme, wherein the indicated first mapping scheme or second mapping scheme is applicable to the second portion, wherein under the first mapping scheme the second portion consists of resource allocation information that indicates at least one group of physical resource blocks that is allocated to the apparatus, wherein under the second mapping scheme the second portion comprises a third portion and a fourth portion, wherein the third portion is indicative of at least one aspect relating to the fourth portion, wherein the fourth portion comprises resource allocation information for resource blocks that are allocated to the apparatus;
• means for utilizing the first portion to determine the indicated mapping scheme to be used for the second portion;
• and
• means for obtaining, based on the determined mapping scheme, the resource allocation information from the second portion.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program instructions, the at least one memory and the computer program instructions being configured to, with the at least one processor, cause the apparatus at least to perform:
• generate a message comprising a resource allocation map, wherein the resource allocation map comprises a first portion and a second portion, wherein the first portion is indicative of a first mapping scheme or a second mapping scheme, wherein the indicated first mapping scheme or second mapping scheme is applicable to the second portion, wherein under the first mapping scheme the second portion consists of resource allocation information that indicates at least one group of physical resource blocks that is allocated to another apparatus, wherein under the second mapping scheme the second portion comprises a third portion and a fourth portion, wherein the third portion is indicative of at least one aspect relating to the fourth portion, wherein the fourth portion comprises resource allocation information for resource blocks that are allocated to the other apparatus, and
• transmit the generated message towards the other apparatus.

A non-transitory computer-readable medium storing a data structure, said data structure comprising:

• a first portion of a resource allocation map;
• and
• a second portion of the resource allocation map,
• wherein the first portion is indicative of a first mapping scheme or a second mapping scheme, wherein the indicated first mapping scheme or second mapping scheme is applicable to the second portion, wherein under the first mapping scheme the second portion consists of resource allocation information that indicates at least one group of physical resource blocks that is allocated to a user equipment, wherein under the second mapping scheme the second portion comprises a third portion and a fourth portion, wherein the third portion is indicative of at least one aspect relating to the fourth portion, wherein the fourth portion comprises resource allocation information for resource blocks that are allocated to the user equipment, wherein the data structure is configured to enable the user equipment to utilize the first portion to determine the indicated mapping scheme for the second portion and to obtain, based on the determined mapping scheme, the resource allocation information from the second portion.
