| 20090262699 | RESOURCE RESERVATION FOR USERS IN A MOBILE COMMUNICATION SYSTEM - The invention relates to a method and scheduling apparatus for reserving radio resources in radio resource block units in a mobile communication system for a plurality of users. Further, another aspect of the invention is the indication of a radio resource reservation in radio resource block units in a mobile communication system to one of a plurality of mobile terminals. To provide a new mechanism allowing an efficient utilization of radio resources the invention proposes a resource reservation mechanism that reserves radio resources for a plurality of users in resource block units. Thereby, individual resource blocks are reserved for the individual users for a reservation period that comprises a plurality of time slots (or sub-frames). Further, the resource block reservations for the users overlap at least partially among the users, i.e. individual ones of the resource blocks are reserved for plural users. | 10-22-2009 |
| 20090262944 | SCRAMBLING OF DATA AND REFERENCE SYMBOLS - The invention relates to a method for scrambling a sequence of symbols comprising at least two reference symbols (R | 10-22-2009 |
| 20100098006 | AVOIDANCE OF FEEDBACK COLLISION IN MOBILE COMMUNICATIONS - The invention relates to feedback transmission for data packets in a mobile communication system. In particular the invention provides a communication system wherein feedback information of a retransmission protocol for transmitted data packets is transmitted. Further, the invention relates to a method for determining radio resources for the transmission of feedback information of a retransmission protocol for transmitted data packets as well as to a base station and a mobile station performing the method. In order to prevent potential collisions of feedback information while omitting a destination identifier for identifying the receiver of the feedback, the feedback resources for sending the feedback are determined at least based on a current transmission counter for a packet. | 04-22-2010 |
| 20100111228 | RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD - Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus ( | 05-06-2010 |
| 20100205518 | RUNNING CYCLIC REDUNDANCY CHECK OVER CODING SEGMENTS - In order to allow early stopping of codeblock decoding iterations, a cyclic redundancy check (CRC) is attached to each codeblock segment that pertains to the same transport block carrying information bits. The CRC for segment k is calculated for all bits within segments | 08-12-2010 |
| 20100208606 | RECEIVER APPARATUS AND COMMUNICATION METHOD - A receiver apparatus wherein the processing amount for CQI (Channel Quality Indicator) measurements in a communication system having a plurality of system bandwidths can be reduced. In this apparatus, a narrow band CQI measurement part ( | 08-19-2010 |
| 20100296427 | Soft-Buffer Management of a Re-Transmission Protocol for Unicast and Multicast Transmissions - The invention relates to a method for transmitting data packets between an eNodeB and a mobile node (MN) when simultaneously using the HARQ protocol with soft-combining for unicast and multicast transmissions. Unicast transmissions are assigned to HARQ processes by the eNB, whereas multicast transmissions need to be assigned to a HARQ process by the MN. According to a first aspect, the soft-buffer memory is strictly separated into a unicast and multicast section, and HARQ protocol operations for unicast and multicast are independent. Due to the separation, the eNB can still correctly assign the unicast transmissions to a HARQ process. According to a second aspect, the soft-buffer is not separated but commonly used for unicast and multicast. However, in order for the eNB to still be able to correctly assign the unicast transmissions to a free HARQ process, the MN assigns the multicast transmission depending on a rule, known also to the eNB. | 11-25-2010 |
| 20110103335 | CONTROL CHANNEL SIGNALLING FOR TRIGGERING THE INDEPENDENT TRANSMISSION OF A CHANNEL QUALITY INDICATOR - The invention suggests a method for providing control signalling in a communication system of generating a control channel signal comprising a transport format and a channel quality indicator trigger signal for triggering a transmission of a channel quality indicator by at least one terminal to the base station, and transmitting the generated control channel signal to at least one terminal, wherein said transport format is a predetermined format for user data transmission by the at least one terminal to the base station and said control channel signal indicates a predetermined mode for reporting the channel quality indicator to the base station, wherein the channel quality indicator transmission is to be triggered by the at least one terminal based on the channel quality indicator trigger signal. | 05-05-2011 |
| 20110107169 | ACTIVATION OF SEMI-PERSISTENT RESOURCE ALLOCATIONS IN A MOBILE COMMUNICATION NETWORK - The invention relates to a method for allocating radio resources to a mobile terminal for data transmission in a mobile communication system as performed by a mobile terminal and a base station, respectively. Moreover, the invention relates to a mobile terminal and a base station to perform such method, as well as an implementation of the method in software. The invention further provides a mobile communication system in which radio resources are allocated to a mobile terminal for uplink transmission. In order to avoid false activation of a semi-persistent resource allocation the invention defines new conditions under which a mobile terminal activates a semi-persistent resource allocation. Unlike for example in prior-art systems, a mobile terminal only activates a semi-persistent resource allocation, if it can confirm the activation command received from the access network. Preferably, the activation command and its confirmation are resource assignments. | 05-05-2011 |
