Effective data rates may be identified, at a master evolved node B (MeNB), for the UE with respect to the MeNB and a secondary evolved node B (SeNB). A downlink split ratio for bearers of the MeNB and the SeNB to the UE may be determined based in part on the effective data rates for the UE. A first portion of data may be sent from the MeNB to the UE according to the downlink split ratio. A remaining portion of data may be sent from the MeNB to the UE via the SeNB according to the downlink split ratio, wherein the UE supports dual connectivity with the MeNB and the SeNB. | 2015-03-26 |
20150085801 | WIRELESS LOCAL AREA NETWORK USING TV WHITE SPACE SPECTRUM AND LONG TERM EVOLUTION SYSTEM ARCHITECTURE - A wireless local area network (WLAN) gateway uses a LTE radio frame and TV white space spectrum for data communications in a wireless local area network. In the LTE downlink frame, a predefined subset of the pilot (reference) symbol positions are used to carry information to data sinks in the WLAN. | 2015-03-26 |
20150085802 | EXTENSION OF PHYSICAL DOWNLINK CONTROL SIGNALING IN A COMMUNICATION SYSTEM - Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol. | 2015-03-26 |
20150085803 | METHOD AND DEVICE FOR TRANSMITTING DATA - The present invention discloses a method and a device for transmitting data, which relate to the field of communications. The method for reporting data transmission includes: when a user equipment UE is electrically powered on, notifying an eNB that the UE has a capability of supporting short latency service, and receiving reporting configuration information transmitted by the eNB; when an short latency service occurs and short latency data corresponding to the short latency service is generated, transmitting, by the UE, the short latency data to the eNB according to the reporting configuration information, or transmitting medium access control layer control elements MAC CE to the eNB according to the reporting configuration information, where the MAC CE includes the short latency data. The device for reporting data transmission includes a notifying module, a receiving module and a transmitting module. The present invention reduces time delay during short latency data transmission. | 2015-03-26 |
