Abstract:
PROBLEM TO BE SOLVED: To transmit data using smaller data overhead in a wireless communication system. SOLUTION: Systems and methods are provided in a synchronous wireless communication system that enables data transmission without specifying information embedded in a packet between wireless mobile user equipment and base stations to reduce transmission overhead thereby. Packets are reordered in the base stations based on a pre-preparation transmitting method in which retransmission of failed packets is expected in a corresponding HARQ instance of the next group.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and method for a time-scalable priority-based scheduler, wherein a flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. SOLUTION: A rate request 408 is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment 418 responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for reverse link rate scheduling. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate power utilization across component carriers (CCs) with different transmission time interval (TTI) configurations. For example, the UE may reserve a portion of the transmit power for a CC with a reduced TTI length (e.g., an enhanced CC (eCC)). In other examples, the UE may dynamically allocate power between CCs with overlapping uplink periods. That is, the UE may borrow power allocated to one CC to transmit on an eCC. The UE may use a prioritization scheme to determine the transmit power for each CC. In some cases, the UE may send a power headroom report based on the power level of the eCC. The power headroom may be a virtual power headroom based on predicted eCC transmission power, or an actual power headroom based on uplink scheduling.
