20080254804 | Scheduling of Mobile Terminals in a Mobile Communication System - The invention relates to a method for scheduling mobile terminals within a mobile communication network and to a base station performing this method. Further, the invention relates to a method for acting upon the reception of scheduling grants in a mobile communication system and to a mobile terminal performing this method. To allow the serving cell to control resource utilization for uplink transmissions of UEs in soft-handover, without thereby decreasing the system throughput of UEs in the serving cell which are not in soft-handover, the invention proposes to use control information transmitted via a shared absolute grant channel to the UEs along with an absolute grant, wherein the control information indicate whether the absolute grant is valid for mobile terminals in soft-handover only. | 10-16-2008 |
20090034487 | HARQ PROCESS RESTRICTION AND TRANSMISSION OF NON-SCHEDULED CONTROL DATA VIA UPLINK CHANNELS - The present invention relates to a method and mobile terminal for performing a data allocation process for scheduled data, non-scheduled user data and non-scheduled control data obeying restrictions on the resource utilization defined by a scheduling grant and at least one non-scheduled grant. Further, the invention relates to a method for transmitting control signaling from a network entity in a radio access network of a mobile communication system controlling the radio resources of mobile terminals to at least one of said mobile terminal and the network entity in a radio access network. In order to reduce the delays to control signaling implied by a conventional HARQ process restriction mechanism the present invention suggests a new categorization of uplink data into scheduled data, non-scheduled user data and non-scheduled control data and a new HARQ process restriction mechanism disabling certain HARQ processes for non-scheduled user data only. | 02-05-2009 |

20120218955 | RADIO BASE STATION APPARATUS, RADIO NETWORK CONTROLLER APPARATUS, COMMUNICATION TERMINAL APPARATUS, TRANSMISSION SIGNAL GENERATION METHOD, AND RADIO COMMUNICATION SYSTEM - A control information channel signal formation unit has a channel encoding section and a spreading section. The channel encoding section multiplexes a plurality of types of control information for a single communication terminal for use in uplink packet transmission, using different symbol patterns between a plurality of types of control information. The spreading section spreads symbols obtained by the channel encoding section using one spreading code. | 08-30-2012 |
