| 20110255492 | METHOD AND DEVICE FOR TRIGGERING OR REPORTING A SCHEDULED REQUEST IN WIRELESS NETWORKS - A method and device for triggering and reporting an SR are disclosed in the present invention. The present invention adds determining of UL-SCH resource scheduling grant and subsequent UL-SCH resource to the process of SR triggering and reporting; with the present invention, the current status of a UE can be accurately determined, and only a necessary SR is triggered and reported. Therefore, not only system overhead can be saved, but also it can be avoided that a base station, in order to respond to the unnecessary SR sent by the UE, allocates redundant UL-SCH resource to the UE, moreover, the system bandwidth is also saved and the system frequency spectrum efficiency is improved. | 10-20-2011 |
| 20120008550 | Relay-Node, Donor-eNB and method for receiving and sending system information - The present invention discloses a Relay-Node (RN), a Donor-eNB and a method for the RN to receive and send system information, which avoid a conflict between simultaneously receiving system information by the RN from the donor-eNB and sending system information to a UE by the RN. The method comprises: setting an offset between a radio frame border of the RN and a radio frame border of a Donor-eNB by the Donor-eNB or the RN itself, so that the radio frame border of the RN is staggered from the radio frame border of the Donor-eNB; receiving and sending system information by the RN according to a sending period specified in a Long Term Evolution (LTE); so as to avoid a conflict between receiving and sending the system information by the RN. | 01-12-2012 |
| 20120092999 | Method and device for relay node access - The present disclosure provides a method and device for Relay Node (RN) access, wherein the method comprises the following steps: a base station sends a downlink message to trigger the RN to switch from monitoring a Physical Downlink Control Channel (PDCCH) to monitoring an RN-dedicated Physical Downlink Control Channel (R-PDCCH), and the RN acquires time-frequency resources for an R-PDCCH from the base station, before or while receiving the downlink message. The present disclosure enables an RN to switch from transmitting according to indication on the PDCCH to transmitting according to indication on the R-PDCCH, i.e., the RN switches from being in a connection state as the UE to being in a connection state as an RN. The present disclosure makes less change to the existing flows, offering advantages of easy implementation, flexible configuration, etc. | 04-19-2012 |
| 20120099515 | RANDOM ACCESS METHOD FOR RELAY NODES - The present invention discloses methods for random access of a Relay Node (RN), which includes one method for random access wherein a RN monitors R-PDCCH and receives a random access response message according to a random access-radio network temporary identifier through the R-PDCCH. By the present invention, the random access procedure of the RN is achieved. | 04-26-2012 |
| 20120176950 | Method and System for Discontinuous Reception (DRX) Configuration - A method for discontinuous reception (DRX) configuration is disclosed, and the method includes: configuring DRXs for a plurality of component carriers, and selecting one or more component carriers as anchor component carriers; controlling the DRXs of other non-anchor component carriers by the anchor component carrier. A system for discontinuous reception (DRX) configuration is also disclosed, and the system includes: a selection and configuration unit, which is used to configure DRXs for a plurality of component carriers and select one or more component carriers as anchor component carriers; a control unit, which is used to control the DRXs of other non-anchor component carriers by the anchor component carrier. By the method and the system, the DRX solution based on the primary carrier is clarified, and the DRX solution based on primary carriers in the stage of conception is improved and concretely implemented. | 07-12-2012 |
| 20120207083 | METHOD AND APPARATUS FOR PROCESSING A DATA TRANSMISSION CONFLICT OF A RELAY-NODE - The present invention discloses a method and an apparatus for processing a data transmission conflict of a relay-node (RN), wherein the method for processing comprises: under the circumstance that the above RN is configured with multi-subframe scheduling resources on a backhaul subframe, if the above RN has acquired dynamic resources on the above backhaul subframe, receiving or sending, by the above RN, data by using the above multi-subframe scheduling resources or the above dynamic resources on the above backhaul subframe, or performing no processing; if the above RN has acquired semi-persistent resources on the above backhaul subframe, receiving or sending, by the above RN, data by using the above multi-subframe scheduling resources or the above semi-persistent resources on the above backhaul subframe, or performing no processing. According to the present invention, the problem of the data transmission conflict is solved, thereby achieving the normal transmission. | 08-16-2012 |
| 20120281614 | Method and system for managing states of relay node - The disclosure discloses a method and a system for managing a state of a relay node. The method comprises switching ( | 11-08-2012 |
| 20120294213 | Optimized method and system for activating and deactivating component carrier in multi-carrier system - The present disclosure provides an optimized method and system for activating and deactivating a component carrier in a multi-carrier system, the method comprises: when activating a Component Carrier (CC), a base station sends an activation command to a User Equipment (UE) through Downlink Control Information (DCI) to indicate the UE to activate the CC; if receiving the activation command successfully, the UE activates the CC and sends an acknowledgement of the activation command to the base station; when deactivating the CC, the base station sends a deactivation command to the UE through the DCI to indicate the UE to deactivate the CC; if receiving the deactivation command successfully, the UE deactivates the CC and sends an acknowledgement of the deactivation command to the base station. The present disclosure can improve the reliability of activation and deactivation of the carrier aggregation technology in an LTE-A system, and has the advantages such as simple configuration and operation, and keeping the status of CC in the base station and the status of CC in the UE consistent. | 11-22-2012 |
| 20120314672 | Method and apparatus for processing buffer status report - A method and apparatus for processing a Buffer Status Report (BSR) are disclosed in the disclosure. At least one of the following processing steps is performed when the BSR is transmitted using Contention Based (CB) uplink resources: A. restarting no retransmission BSR timer (retxBSR_Timer) when an uplink grant indicating CB uplink resources is received; B. restarting no retxBSR_Timer and/or no periodic BSR timer (PeriodicBSR_Timer) when the uplink resources are available; C. cancelling no triggered BSR when a BSR-related Media Access Control Protocol Data Unit (MAC PDU) is formed by occupying the uplink resources; and cancelling the triggered BSR when an indication for a successful transmission of the BSR-related MAC PDU is received; D. determining, according to a type of a triggered BSR, whether or not to cancel the triggered BSR, when a BSR-related MAC PDU is formed by occupying the uplink resources; and cancelling the triggered BSR when an indication for a successful transmission of the BSR-related MAC PDU is received. With the disclosure, the influence on User Equipment (UE) due to the failure of the BSR transmission when the BSR is transmitted by occupying the CB uplink transmission resources is decreased. | 12-13-2012 |
