Transmission of advanced-MAP information elements in mobile networks
View Patent ↗An apparatus that transmits Advanced-MAP (A-MAP) information in a mobile communication network determines whether or not to split an information element to two or more parts that will be transmitted in two or more logical resource units. Each part of information element in a logical resource unit includes an indicator to indicate that a second part exists in another subsequent logical resource unit. In one embodiment, the mobile communication network is used in conjunction with orthogonal frequency division multiple access (OFDMA) techniques.
1. A network system, comprising:
a processor;
a memory coupled to the processor; and
a communication device coupled to the processor to communicate wirelessly over
multiple sub-channels in an orthogonal frequency division multiple access (OFDMA) wireless network, wherein the communication device is operable to:
divide an information element into two or more logical resource units (LRUs) for transmission in a downlink signal to at least one mobile station, the information element comprising control information for the at least one mobile station that indicates which resources are allocated to the at least one mobile station, the information element being mapped onto at least one frequency block and at least one time slot of each of the two or more LRUs; and
set an indication in a first part of the two or more LRUs to indicate that the information element will comprise two or more LRUs;
wherein the indication indicates whether or not to perform concatenation of the two or more LRUs to retrieve a complete version of the information element; and
wherein the control information comprises assignment information, hybrid Automatic Repeat Request (HARQ) feedback information, or power control information.
2. The system of claim 1 , wherein the two or more logical resource units are non-contiguous and are of different logical unit groups.
3. The system of claim 1 , wherein the indication comprises:
a first value indicative of a subsequent part of the information element; and
a second value indicative of whether the first part is the beginning part of the information element.
4. The system of claim 1 , wherein the two or more LRUs each further comprise information for an integrity check.
5. The system of claim 1 , wherein the information element comprises an advanced MAP (A-MAP) information element.
