Problems solved by technology

[0035] Note that, as is often the case, when the MCS of a PHY burst containing a VoIP packet is more efficient than that of a MAP message, the signaling overhead is even greater compared to the payload

Embodiment Construction

[0065] Described herein is a novel bandwidth allocation mechanism for use in IEEE 802.16 (but not necessarily limited to this particular standard) that meets the IEEE 802.16m requirements for VoIP capacity. For convenience and not as a limitation, this approach may be referred to as a HARQ-enabled cyclic bandwidth allocation method. Several important aspects of this approach include, but are not limited to, the following:

[0066] A) Mechanism and signaling of the cyclic bandwidth allocation method;

[0067] B) a new MAC header, which can further reduce the MAC overhead when using the round-robin bandwidth allocation method, or can enhance the amount of signaling information that can be conveyed through the MAC header; and

[0068] C) HARQ support for the novel cyclic bandwidth allocation method (including HARQ channel allocation, ACK feedback channel allocation and overall signaling approach).

[0069] These and other aspects of exemplary embodiments according to the invent...

Abstract

A method is described that includes allocating transmission resources for transmitting data packets. The allocation of transmission resources includes periodic allocation of transmission resources applicable to multiple frames. The allocation of transmission resources includes allocation of transmission resources for the first transmission of each HARQ process during multiple frames. The method includes receiving an indication of an allocation of transmission resources for data packets in a plurality of frames. Receiving and / or transmitting packets over multiple frame periods using allocation of transmission resources is also included in the method. Frames of the plurality of frames may include compressed MAC headers. Equipment and computer procedures are also described.
