The method also includes sending the symbol sequence to a user equipment (UE) over a high speed shared control channel (HS-SCCH). | 2014-10-16 |
20140307674 | BUFFER STATUS REPORTING IN A MOBILE COMMUNICATION SYSTEM - The invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission. | 2014-10-16 |
20140307675 | PILOT STRUCTURES FOR ACK AND CQI IN A WIRELESS COMMUNICATION SYSTEM - Techniques for transmitting data and pilot for control information are described. In one aspect, a user equipment (UE) may spread a reference signal sequence with a first orthogonal sequence to obtain multiple pilot sequences. The UE may then send the multiple pilot sequences on multiple subcarriers in multiple symbol periods, one pilot sequence in each symbol period. The UE may modulate the reference signal sequence with control information (e.g., ACK information) to obtain a modulated sequence. The UE may spread the modulated sequence with a second orthogonal sequence to obtain multiple data sequences. The UE may then send the multiple data sequences on the multiple subcarriers in multiple symbol periods for data. In another aspect, the UE may send multiple pilot sequences on multiple subcarriers in multiple symbol periods separated by at least one symbol period, one pilot sequence in each symbol period. | 2014-10-16 |
20140307676 | System and Method for Uplink Control Information Transmission in Carrier Aggregation - A method for communicating uplink control information to a base station using a user equipment is presented. The method includes identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions, and identifying at least one first ranking for each of the component carriers for transmission of uplink control information. Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station. | 2014-10-16 |
20140307677 | Conditional Uplink Timing Alignment in a Mobile Station Device of a Radio Communication System - A mobile station device transmits a random access preamble to a base station device. The base station device receives the random access preamble from the mobile station device and transmits, to the mobile station device, a Random Access—Radio Network Temporary Identity (RA-RNTI) which notifies a resource assignment of a random access response. The mobile station device further monitors downlink control channels while detecting both a Cell—Radio Network Temporary Identity (C-RNTI) and the RA-RNTI, in which a downlink control channel includes the RA-RNTI and a downlink control channel includes the C-RNTI which notifies a resource assignment of downlink data. Upon detection of the C-RNTI and the RA-RNTI in a same sub-frame, the mobile station receives both the random access response and the downlink data, or receives either the random access response or the downlink data. | 2014-10-16 |
20140307678 | METHOD AND APPARATUS FOR UTILIZING MULTIPLE CARRIERS IN HIGH SPEED PACKET ACCESS COMMUNICATIONS TECHNICAL FIELD - A method and an apparatus for utilizing multiple carriers are disclosed. A wireless transmit/receive unit (WTRU) capable of receiving on a single downlink carrier at a time may tune the receiver to one downlink carrier and switch the downlink carrier in accordance with a configured pattern. The WTRU may switch the carrier from an anchor carrier to a non-anchor carrier at a high speed shared control channel (HS-SCCH) sub-frame boundary, and switches back at an end of a subsequent high speed physical downlink shared channel (HS-PDSCH) subframe. The WTRU may switch the carrier at an HS-PDSCH sub-frame boundary. A WTRU capable of receiving on multiple downlink carriers simultaneously may tune the receiver to an anchor carrier and a supplementary carrier, and switch the supplementary carrier to another carrier based on a carrier switching order. The carrier switching order may be received via an HS-SCCH or via layer | 2014-10-16 |
