Half-frame request opportunities and operation within wired and/or wireless communication systems

摘要

A communication device is configured to receive a message that indicates request opportunity parameter(s). Based on the request opportunity parameter(s), the communication device is configured to generate and transmit a transmission request within one of two or more request opportunities (e.g., 2, 3, 4, etc. or generally N request opportunities such that N is a positive integer greater than or equal to 2) indicated by the request opportunity parameter(s). The two or more request opportunities are included within mini-slot(s) that span OFDM sub-carrier(s) of OFDM or OFDMA framing. A given mini-slot spans an OFDM or OFDMA frame, and a mini-slot is divided into any desired number of portions (e.g., 2, 3, 4, etc. or generally N portions) such that each of the request opportunities within that mini-slot occupies a common fraction of the mini-slot (e.g., each occupies ½, ⅓, ¼, etc. or generally 1/N of the mini-slot).

主权项

1. A communication device comprising:
a communication interface configured to:
receive a message that indicates a plurality of request opportunities, wherein the plurality of request opportunities are characterized by one or more request opportunity parameters including locations of the plurality of request opportunities within a mini-slot that spans one or more orthogonal frequency division multiplexing (OFDM) sub-carriers of an OFDM or orthogonal frequency division multiple access (OFDMA) frame; andtransmit a transmission request within one of the plurality of request opportunities; and a processor configured to:
process the message to extract the one or more request opportunity parameters; andgenerate the transmission request based on the one or more request opportunity parameters.
