20140091844 | SPUR SUPPRESSION IN A PHASE-LOCKED LOOP - An apparatus and method for reducing effects of spurs in a phased-locked loop having a sigma-delta modulator and digital circuits. The apparatus includes a clock dithering circuit coupled to each of the sigma-delta modulator and the digital circuits. Each clock dithering circuit is configured to dither flanks of a respective first and second clock input signal, and generate a dithered clock output signal, one for each of the sigma-delta modulator and digital circuits. A frequency of each dithered clock output signal follows a frequency of the respective first and second clock input signals, and a phase between each dithered clock output signal and the respective first and second clock input signal is shifted and constantly changing. | 04-03-2014 |
20120076092 | DATA TRANSMISSION METHOD AND APPARATUS - Embodiments of the present invention provide a data transmission method and apparatus. ROHC packets that use a same Context ID are encapsulated into MAC PDU, wherein the MAC PDU is formed by a MAC PDU packet header and a MAC PDU payload. The Context ID of the ROHC packets is carried in the MAC PDU packet header, and the Context ID is not carried in the ROHC packets. The MAC PDU is sent. In this way, transmission resources are saved, and transmission efficiency is improved. | 03-29-2012 |
20110243091 | USER EQUIPMENT, METHOD FOR DETERMINING RESOURCE, METHOD FOR REPORTING RESOURCE, AND SYSTEM FOR DISTRIBUTING RESOURCE - A User Equipment (UE), a method for determining a resource, a method for reporting a resource, and a system for distributing a resource are provided. The method for determining a resource includes: if transmission data on the carrier reaches maximum transmission data supported in a scope allowed by Service Grant (SG), and a transmission power of the UE is capable of improving a data transmission rate of the carrier, and the carrier and the other one carrier of the dual carriers are incapable of completing transmitting total buffer status data in the same delay period, determining that a resource distributed to a UE on one carrier of dual carriers of the UE is insufficient; otherwise, determining that the resource distributed for the UE on the carrier is sufficient. Therefore, a solution for reporting the resource of the dual carriers is provided, so as to improve a network performance. | 10-06-2011 |
20090201922 | METHOD FOR CHANGING SESSION MEDIA, METHOD FOR ESTABLISHING A CALL, AND EQUIPMENT THEREOF - A method for changing ICS session media includes: receiving a media type change request including a new media type sent from a terminal equipment or a MSC, releasing a CS call leg based on an original media type between an ICCF and the terminal equipment, establishing a CS call leg based on the new media type between the ICCF and the terminal equipment, and updating a media type of a second call leg between the ICCF and a second party into the new media type; or, receiving a media type change request including a new media type sent from a second party, updating a media type of a second call leg between an ICCF and the second party into the new media type, releasing a CS call leg based on an original media type between the ICCF and a terminal equipment, and establishing a CS call leg based on the new media type between the ICCF and the terminal equipment. | 08-13-2009 |
