20120307919 | Control of Cell Search Procedure - A method, an apparatus and a computer program product for wireless communication, wherein the LTE HSPA carrier aggregation includes an improved HARQ feedback by optimizing the radio interface for the uplink direction. | 12-06-2012 |
20130016703 | User Identifier Multiplexing By Time DivisionAANM Ranta; Jukka TapioAACI KaarinaAACO FIAAGP Ranta; Jukka Tapio Kaarina FI - A network assigns to a first user equipment UE and to a second UE a same temporary identifier for use at least while the first and the second UEs are simultaneously in a connected state in a same cell. Individual control channel transmissions utilizing the temporary identifier are selectively associated to only one of the first and the second UEs according to a predetermined time domain division. In various embodiments the time domain division comprises discontinuous reception DRX periods having mutually exclusive reception time periods; or mutually exclusive radio frame or subframe groups assigned to the first and second UEs for at least downlink control channel transmissions. Such radio frame/subframe groups may be even and odd numbered, or may be given by any of various example formulas if there are two or more UEs sharing the same temporary identifier. For an LTE system such an identifier may be the C-RNTI. | 01-17-2013 |
20130250870 | Interference Control - Mechanisms for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between an UL communication performed on at least one frequency band and a DL communication performed on another frequency band is determined, a partial denial processing is conducted so as to deactivate a dedicated part of resource blocks used for the first communication on the at least one frequency band of the first communication in the case of an interference situation being determined. The first communication is then continued in parallel to the second communication, on the basis of resources different from the dedicated part of resource blocks deactivated in the partial denial processing. | 09-26-2013 |

20150195217 | METHODS AND APPARATUS FOR TRANSMITTING DATA - A method, apparatus and computer program product are provided for facilitating transmission of data. A method and apparatus may detect one or more items of data that were transmitted with at least one error or unsuccessfully delivered to a device. The method and apparatus may enable retransmission of the items of data in at least one transport block. The method and apparatus may enable transmission of one or more items of new data in the at least one transport block such that a size of the new data does not exceed a variable size limit of a transport block size. The variable size limit may be dependent on one or more sizes of one or more transport blocks. The method and apparatus may determine that the variable size limit comprises a size smaller than a size of the at least one transport block. | 07-09-2015 |
20150195848 | APPARATUSES, METHODS AND COMPUTER PROGRAM PRODUCTS RELATED TO IMPROVEMENTS IN AUTONOMOUS DENIAL PROHIBITION MECHANISMS - Aspects of the invention en-compass an apparatus and corresponding method and computer program product, wherein the apparatus comprises a controller, configured to cause communication via a first and at (east a second radio access technology, provide for setting of rules, which permit the apparatus to autonomously deny communication via the first radio access technology, detect a predetermined event in terms of the second radio access technology, responsive thereto, apply the rules and deny a communication via the first radio access technology, detect an occurrence of a further predetermined event in terms of the second radio access technology, while the rules prohibit to further deny a communication via the first radio access technology, decide, responsive thereto, to violate the rules and to permit to deny a further communication via the first radio access technology, and cause transmission of a violation indication to a destination of the communication via the first radio access technology. A network entity apparatus and corresponding method and computer program product are also envisaged. | 07-09-2015 |
20150289312 | METHOD AND APPARATUS FOR PACKET TUNNELING - A method, apparatus and computer program product are provided herein for enabling a D2D bearer to stay alive even in an instance in which a D2D connection is lost. In some example embodiments, a method is provided that comprises detecting a condition that indicates that a device-to-device bearer is to be terminated. The method of this embodiment may also include modifying a cellular bearer protocol data unit header, such that the cellular bearer protocol data unit header indicates that a cellular bearer service data unit is a device-to-device protocol data unit. The method of this embodiment may also include causing one or more device-to-device protocol data units to be encapsulated within one or more cellular bearer protocol data units, such that the one or more device-to-device protocol data units are transmitted via a cellular bearer. | 10-08-2015 |
20150304896 | HANDOVER FROM D2D TO CELLULAR WHEREBY A PDCP ENTITY IS ASSOCIATED WITH TWO RLC ENTITIES RELATED TO DIFFERENT RADIO BEARERS - The application relates to a mobile terminal radio stack for D2D single channel ( | 10-22-2015 |
20150305065 | RANDOM ACCESS PROCEDURE AND RELATED APPARATUS - A new random access procedure is introduced that does not use a timing advance for the uplink timing but instead uses the downlink timing for uplink timing. This is particularly viable when the propagation delay is short, for example with local area cells having a coverage range less than some predetermined threshold. From the mobile terminal's perspective it obtains downlink timing for a cell, transmits a scheduling request SR in a contention-based uplink resource, and in response to receiving an uplink resource allocation it transmits in the allocated uplink resource using the downlink timing. The terminal can get the configuration for that contention-based uplink resource from system information. From the uplink resource the terminal and network determines a SR-RNTI, which the network uses to address the uplink resource allocation and the terminal uses to find a pre-defined search space in which to look for that uplink resource allocation. | 10-22-2015 |
