| 20100195544 | Apparatus and Method for Communicating Uplink Signaling Information - A User Equipment, UE, of a cellular communication system transmits scheduling assistance data to a base station comprising a base station scheduler which schedules uplink packet data. The scheduling assistance data relates to uplink packet data transmission from the UE. The UE comprises a channel controller which is operable to cause the scheduling assistance data to be transmitted from the UE to the base station in a first physical resource of an uplink air interface. The first physical resource is not managed by the base station based scheduler. The scheduling assistance data may specifically be transmitted in a first transport channel multiplexed with other transport channels on a physical resource. The transport channels may be individually optimized and may have different termination points and transmission reliabilities. Specifically, the transport channel supporting the scheduling assistance data signaling may have a high reliability and be terminated in the base station. | 08-05-2010 |

| 20110170459 | DISTINGUISHING BETWEEN DATA PACKETS SENT OVER THE SAME SET OF CHANNELS - Embodiments of the present invention distinguish a first type of data packet transmitted over a random access communication channel of a wireless cellular communications system from a second type of data packet transmitted over the same random access communication channel, allowing the first and second data packet data packet types to share a common set of random access channels through the use of different types of channel coding. This reduces data packet collision probability by eliminating the need to segregate the set of random access channels according to data packet type. Backward compatibility with legacy base stations that handle only the first data packet type is maintained in that no changes to the first data packet type are needed. | 07-14-2011 |

| 20110228712 | UPLINK RESOURCE ALLOCATION TO CONTROL INTERCELL INTERFERENCE IN A WIRELESS COMMUNICATION SYSTEM - Embodiments of the present invention exploit the reciprocity of radio channels in TDD, and longer-term correlation between average uplink and downlink path losses in FDD wireless communication systems to enable distributed schedulers in an enhanced uplink system to allocate uplink transmission resources while preemptively managing intercell interference levels. Each cell's base station transmits a downlink reference signal at a known transmission power level. A mobile station monitors the received signal strength of the downlink reference signals from multiple base stations. The transmitted and received signal strength levels can be used by the mobile station to estimate the amount of intercell interference that the mobile station's uplink transmissions cause, and the mobile station's uplink transmission parameters are adjusted accordingly. In further embodiments, the received reference signal power levels, or values derived therefrom, are transmitted by the mobile station to its serving base station, where a scheduling algorithm uses the information to adjust one or more transmission parameters relating to a grant of uplink transmission resources to the UE, thereby controlling the intercell interference generated by the mobile station's uplink transmissions. | 09-22-2011 |
