20100322098 | METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM - A method for sending buffer status information includes checking if a quality of service (QoS) parameter is defined for a first logical channel and at least one condition of a set of predetermined conditions associated with a logical channel group is fulfilled. If the QoS parameter is defined and at least one condition of the set is fulfilled, the method includes setting a number of bits in a media access control header according to a first semantic. The bits carry buffer status information, and the first semantic is based on the QoS parameter of the first logical channel. Otherwise, the method includes setting the number of bits carrying the buffer status information according to a second semantic that is based on an amount of data available for transmission across the logical channel group. | 12-23-2010 |

20140086062 | DETERMINING HEARABILITY IN A HETEROGENOUS COMMUNICATION NETWORK - A method for determining whether a radio unit in a shared cell configuration is hearable by a user equipment is provided. Transmission of a probe message to the user equipment by the radio unit is caused. The probe message invokes a probe response from the user equipment if the radio unit is hearable by the user equipment on a downlink channel. The radio unit is hearable by the user equipment if the downlink channel performance between the radio unit and the user equipment meets a predetermined signal criteria. An uplink channel associated with the user equipment is monitored for the probe response from the user equipment after transmission of the probe message. Hearability data associated with the user equipment is determined based on the monitored uplink channel. The hearability data indicates whether the radio unit is hearable by the user equipment the downlink channel. | 03-27-2014 |

20140119287 | QUEUE SPLITTING FOR PARALLEL CARRIER AGGREGATION SCHEDULING - A method and system for carrier aggregation scheduling in a communication system are disclosed. According to one aspect, a method for carrier aggregation scheduling includes selecting a set of at least one component carrier from a group of candidate component carriers upon which to transmit data in a queue. The selecting of all component carriers in the set is performed prior to determining an amount of data to be assigned to any one of the component carriers in the set. Blocks of data from the queue are assigned to at least one of the component carriers in the set of selected component carriers based at least in part on an estimated amount of data that can be carried by each component carrier in the set. | 05-01-2014 |
20150023235 | Flexible Downlink Subframe Structure for Energy-Efficient Transmission - Disclosed herein are methods for using new energy-saving subframe structures, as well as corresponding apparatus that are configured to exploit these energy-saving subframes. In these energy-saving subframes, some, but not all, of the individual OFDM symbols in a subframe are inactive, meaning that no signal is transmitted during at least a part of the symbol time of the blanked symbols. An example method according to these techniques may be implemented in a radio transceiver, such as an LTE eNodeB, and comprises transmitting, in a first symbol time of a downlink subframe that comprises a plurality of symbol times, a codeword indicating that the downlink subframe includes at least one inactive symbol time. The method further includes transmitting data during at least one but fewer than all of the remaining ones of the plurality of symbol times in the downlink subframe. Corresponding techniques for receiving the energy-saving subframes are also disclosed. | 01-22-2015 |

According to one aspect, the invention provides a finite state machine having a plurality of states facilitating secondary cell activation and deactivation decisions. The states of the finite state machine include a deactivated state and an activated state. In the deactivated state, a secondary cell is deactivated and a media access control element, MAC CE, for deactivation is sent to the UE. The base station in the deactivated state is not allocating resources for maintaining transmission on the secondary cell. In the activated state, the secondary cell is active and a MAC CE for activation is sent to the UE. In the activated state, the base station is ready to transmit on the secondary cell. | 03-19-2015 |
