  • Patent number: 8099643
    Abstract: A method and system for minimizing slot wastage by overlapping HARQ regions in a communication system. A control region allocation (CRA) utility defines a group of HARQ regions for transmission of control data. A HARQ region definition includes a starting symbol and a starting sub-channel number for the HARQ region, a number of symbols and a number of sub-channels to define the dimensions of the region and the slot duration for each sub-burst in a sequence of allocated sub-bursts. The CRA utility overlaps one HARQ region with the other to minimize slot wastage. The slots that carry data in one HARQ region overlap un-used slots in another HARQ region or are overlapped with a dummy allocation in the other HARQ region. Since mobile stations do not carry data for the slots with a dummy allocation, the overlap of HARQ regions avoids conflict with the HARQ operation.

  • Publication number: 20090305715
    Abstract: A wireless communication system comprises a scheduler for scheduling air interface data for a plurality of user equipments. A control channel scheduler estimates a scheduling time for a scheduling of air interface data to a first user equipment of the plurality of user equipments in response to a current scheduling metric for the first user equipment and a reporting processor generates a channel quality reporting request for the user equipment in response to the scheduling time. The channel quality reporting request is transmitted to the user equipment which proceeds to provide channel quality reports in accordance with the request. The approach may improve performance in a wireless communication system by reducing channel reporting resource requirements while still providing channel quality information when needed. The invention may be particularly suitable for a Long Term Evolution 3rd Generation Partnership Project cellular communication system or an IEEE 802.16 wireless communication system.

  • Patent number: 7342939
    Abstract: Various embodiments are described to address the need for an apparatus and method for providing uplink communication resources that reduce some of the existing delays in acquiring these resources. In general, they may involve a RAN (121) transmitting data to a remote unit (101) via a downlink communication resource. After transmitting the data and with no additional data ready for transmission, the RAN begins transmitting assignment messages to the remote unit for an uplink resource. However, these assignment messages are not transmitted in response to uplink resource requests from the remote unit. In addition to or alternatively, the RAN detects a regular pattern in uplink activity of the remote unit and then begins predicting, based on the pattern, when the remote unit will next need an uplink resource. When the remote unit is predicted to need an uplink resource, the RAN transmits an assignment message to the remote unit.

  • Patent number: 6845235
    Abstract: A base station (400) and corresponding method (300) sends (302) a first request for an acknowledgment message from a mobile unit (502), the acknowledgment message including an uplink channel request when needed by the mobile unit. The base station determines (304) an expected time for receiving the acknowledgment message. In response to not receiving the acknowledgment message by the expected time, the base station conditionally sends (308) a speculative packet access reject message to the mobile unit, followed by a second request for the acknowledgment message.
