20130195030 | Method and Arrangement in a Telecommunication System - Systems and methods avoid the need to coordinate preambles between UEs performing random access on their PCells and SCells. According to an embodiment, a method for random access in a radio communication system includes: transmitting, by a network node, a random access response including a Radio Network Temporary Identifier (RNTI) which has a first value if the random access is associated with a first cell and a second value if the random access is associated with a second cell, the first value being different than the second value and the first cell being different from the second cell. | 08-01-2013 |

20140071860 | Setting Timers when Using Radio Carrier Aggregation - The present invention relates to a method of a user equipment (UE) using discontinuous reception (DRX) and time division duplex (TDD) carrier aggregation of at least a first and a second cell, the first cell | 03-13-2014 |
20140071868 | APPARATUSES AND METHODS FOR MANAGING PENDING HARQ RETRANSMISSIONS - Methods and systems present solutions to, for example, the problem of unnecessary preparedness for suspended retransmissions in the user equipment (UE) which contributes to power drain in the device battery. One method for monitoring a Physical Downlink Control Channel (PDCCH) for adaptive retransmission grants in a radio communication system includes: monitoring, by a user equipment (UE), the PDCCH for adaptive retransmission grants; receiving, by the UE, a hybrid automatic repeat request (HARQ) acknowledge (ACK) message, and ceasing, by the UE, to monitor the PDCCH for adaptive retransmission grants after receipt of the HARQ ACK message. | 03-13-2014 |

20140198701 | Deciding Whether to Send Uplink Control Signaling Based on the Active Time Status of a User Equipment Configured with Discontinuous Reception (DRX) - A method in a user equipment for deciding whether or not to send an uplink transmission (ie. Channel State Information, CSI, and/or Sounding Reference Signal, SRS) to a radio access network node (Node B) is provided. The user equipment and radio access network node (Node B) are comprised in a communications network. The user equipment is configured with Discontinuous Reception, DRX, to be in active time or not be in active time. The user equipment decides ( | 07-17-2014 |
20140204820 | Method and Arrangement in a Telecommunication System - The present disclosure relates to a method in a network node for controlling DRX to be applied by a user equipment, UE, connected to said network node. Said network node can order the UE to enter a first DRX cycle by means of a specific control element. The method comprises the step of ordering the user equipment to enter a second DRX cycle by means of a modified usage of said specific control element. The disclosure furthermore relates to a network node, a method in a user equipment and a user equipment. | 07-24-2014 |

20140233542 | METHOD AND MOBILE NODE FOR DETERMINING A POINT IN TIME FOR TRANSMISSIONS - Method and mobile node in a wireless communication network for determining when to transmit a signal. The mobile node operates in a wireless communication network comprising a first cell and a second cell where the mobile node is synchronized to the first cell. The method comprises determining a timing reference based on a reception of a downlink transmission in the first cell and transmitting the signal, to be received in the second cell, at a point in time based on the timing reference and a timing advance value of the first cell. | 08-21-2014 |
20140369325 | TERMINAL AND METHOD FOR HANDLING TIMING REFERENCE IN A WIRELESS NETWORK - According to a first aspect of embodiments herein, the object is achieved by a method in a terminal for handling a timing reference. The terminal is served by multiple serving cells of a wireless network, and is configured with a first Timing Advance, TA, group comprising the multiple serving cells, one of which, a current TR cell, acts as the timing reference for the multiple serving cells. When the current TR cell becomes unavailable for the terminal, the terminal autonomously selects a new TR cell to act as the timing reference for the multiple serving cells in the TA group. | 12-18-2014 |
