| 20110116364 | Method for processing collision between random access procedure and measurement gap - A method for processing a collision between a random access procedure and a measurement gap, which involves a terminal and a base station, and the terminal is configured with a measurement gap; the method includes: when the random access procedure is a contention-based random access procedure, the terminal cancels the measurement gap if a random access response window or the operating time of a contention resolution timer has an overlap with the measurement gap. The concrete solution, that the priority of the random access procedure is higher than that of the measurement gap in the method provided by the present invention, improves the reliability of the random access procedure, reduces failure probability of the random access procedure, reduces the delay of the random access procedure, and effectively utilizes a measurement gap. | 05-19-2011 |
| 20120120886 | Method and UE for setting a Happy bit on an uplink E-DPCCH - A method and UE for setting a Happy bit on an uplink enhanced dedicated control channel are provided. The method includes: a UE transmits an uplink Enhanced Dedicated Channel (E-DCH) on more than one carrier, when criterion 1 and criterion 2 are met, the UE sets the Happy bit which is to be transmitted to a network side as “UNHAPPY” to indicate that the UE doesn't satisfy with the current serving grant. The disclosure optimizes the processing process of power control and resource scheduling, reduces call-drop rate, so that the performances of the UE and the NodeB are optimized. | 05-17-2012 |
| 20120127867 | Method and apparatus for transmitting/receiving hybrid automatic repeat request failure indication - The present application discloses a method and apparatus for transmitting/receiving an HARQ failure indication. The method includes: a Node B receives an E-DCH payload from a primary carrier and fails to decode it; the Node B determines whether the condition of transmitting an HARQ failure indication is met, if so, the Node B sets the HARQ failure indication data frame on the primary carrier; and the Node B transmits the HARQ failure indication data frame to a service radio network controller on a transmission bearer corresponding to the primary carrier. The present application realizes a better control over the SIR target value through a carrier-based outer loop power control function. | 05-24-2012 |
| 20120134276 | Harq Failure Indication Method, Harq Failure Indication Data Frame and Service Node B Thereof - The present invention provides a Hybrid Automatic Repeat Request (HARQ) failure indication method, an HARQ failure indication data frame and a Serving Node B thereof. In the above method, when the decoding of the received Enhanced Dedicated Transport Channel (EDCH) data frame is unsuccessful and the condition of sending HARQ failure indication is satisfied currently, Serving Node B sends an HARQ failure indication data frame to the Service Radio Network Controller (SRNC). Wherein, a carrier identifier which indicates the carrier on which the HARQ failure happens is carried in the HARQ failure indication data frame. According to the present invention, when the SRNC receives the HARQ failure indication data frame, SRNC can perform Outer Loop Power Control (OLPC). | 05-31-2012 |
| 20120135762 | Method and Apparatus for Communication Control Between Radio Network Controllers - The present invention provides a method for communication control between radio network controllers. The method comprises: after a serving node B belonging to a drift radio network controller controls a terminal to perform activation of an enhanced dedicated channel radio link, notifying a radio link activation information of the terminal to the drift radio network controller; and the drift radio network controller sending a radio link activation indication to a serving radio network controller according to the radio link activation information; and, after the serving node B belonging to the drift radio network controller controls the terminal to perform deactivation of the enhanced dedicated channel radio link, notifying a radio link deactivation information of the terminal to the drift radio network controller; and the drift radio network controller sending a radio link deactivation indication to the serving radio network controller according to the radio link deactivation information. | 05-31-2012 |
| 20120140751 | METHOD FOR TRANSMITTING FRAME SEQUENCE NUMBER, NODE B AND SERVICE RADIO NETWORK CONTROLLER - The present invention discloses a method for transmitting a frame sequence number and a node B and a serving radio network controller, which method comprises: a node B receiving a protocol data unit from a carrier and de-multiplexing the protocol data unit into media access control data streams; the node B inserting a carrier symbol into a carrier indicator field of an enhanced-dedicated transport channel data frame and generating a frame sequence number for every the enhanced-dedicated transport channel data frame transmitted on the carrier; and the node B transmitting the media access control data streams to a serving radio network controller SRNC by using the enhanced-dedicated transport channel data frame. By virtue of the present invention it achieves that the SRNC is capable of obtaining the information regarding network layer data transmission in dual-carrier situation so as to detect the loss of data frames. | 06-07-2012 |
| 20120147873 | METHOD AND TERMINAL FOR SYNCHRONIZING SUBORDINATE CARRIER CELL - Disclosed are a method and a terminal for synchronizing a subordinate carrier cell, which method comprises the following steps of: after a terminal receives an activation uplink subordinate carrier order from a service node B, the terminal, with the current time as a reference, carrying out synchronization in a cell in an activation set of the enhanced dedicated channel of the subordinate carrier under a non-service node B at a first time point after having carried out delay according to an acquired subordinate carrier activation processing offset time period. The present technical solution reduces the time delay required by synchronization and inter-cell interference and enables the cell capacity and coverage to be unaffected. | 06-14-2012 |
