摘要： Disclosed is a paging control method in a telecommunications system where devices are paged by paging requests from base stations, the base stations being controlled by paging control messages from a network node. The method involves detecting (310), in the network node, a need to initiate paging of a device. Then, a set of candidate base stations in an area of the telecommunications system is determined (320) by the network node. The candidate base stations are potentially capable of reaching the device in the area by sending paging requests at respective paging occasions. The network node selectively controls (330) paging control messages intended for the set of candidate base stations depending on detection of a paging response made by the device via one of the base stations in the set of candidate base stations, so as to prevent paging requests from base stations, in the set of candidate base stations, which have not yet sent any paging requests to the device..

摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

摘要： A method in a base station for selecting a set of transport format schemes for a cell is provided. The set of transport format schemes shall be used for a radio transmission from a communication device to the base station. The base station is serving the eel! comprising the communication device. The communication device is unsynchronized for transmission to the base station. The base station specifies (201) a plurality of sets of transport format schemes. Each set of transport format schemes is associated to a respective guard time, which guard time is a time margin required to compensate for the communication device being unsynchronized for transmission to the base station. After determining (203) a required guard time as the maximum timing advance value used in the cell the base station selects (204) one set of transport format schemes from the plurality of sets of transport format schemes to be available for the cell. The set is selected such that its associated guard time matches the determined required guard time in the cell.

摘要： Embodiments herein relate to a method in a radio base station (12) for providing radio coverage to a user equipment (10). The radio base station (12) comprises at least two radio antenna ports; a first antenna port (AP11) associated with a first physical antenna and a second antenna port (AP12) associated with a second physical antenna. The first antenna port (AP11) is arranged to provide a radio coverage over a first area (14) and the second antenna port (AP12) is arranged to provide a radio coverage over a second area (17). The radio base station (12) broadcasts a signal with system information over the first area (14) enabling the radio base station (12) to connect to the user equipment (10). The radio base station (12) also determines that a user equipment (10) in the first area (14) is to receive or transmit data. The radio base station (12) then obtains information related to a position of the user equipment (10) in the first area (14). The radio base station (12) then sets a characteristic of the second physical antenna based on the obtained information. Thereby to the radio base station provides radio coverage to the user equipment (10) via the second port (AP12).

摘要： The present invention relates a User Equipment, UE (204) and a Radio Base Station (202, 206) and methods therein for contention resolution in general. Based on measured and analyzed measurements of a radio connection establishment response from each of at least a first and a second Radio Base Station, a UE receiving said radio connection establishment response can resolve the contention by selecting a RBS based on the received power of a set of DL reference signals as received by the UE, of the received power of the radio connection establishment responses, on timing of the received sets of reference signals, on timing of the radio connection establishment responses, on historic RBS selections, on priority level of the RBS, to mention a few alternatives.

摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing do, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要： PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index i that identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.
