The embodiments of the present invention relate to apparatuses in the form of a first network unit and a device, and also relates to a method for enabling protection of a bootstrap message in a device management network system. The method comprises: receiving at the first network unit, a request to bootstrap the device; transmit a request for a bootstrap key, to a second network unit; receiving a message comprising the bootstrap key and further comprises trigger information and transmitting the trigger information to the device to trigger generation of the bootstrap key internally in the device. Thereafter a protected bootstrap message can be transmitted to the device from the first network unit, and when the device verifies and/or decrypts the bootstrap message, device management (DM) sessions can start between the device and the first network unit.

Apparatuses and a method for protecting a bootstrap message in a network

The present invention relates to methods and arrangements for facilitating an efficient connection setup. The present invention specifies rules for defining the signaling of connection setup messages from user equipments such as to apply one single transmission if an assigned uplink transmission grant for transmitting the connection setup messages is sufficiently large while applying separate transmissions if the size indicated in said uplink transmission grant is not sufficient. Thus, a sufficiently large grant allows a parallel execution of the connection setup messages.

Conditional parallel execution of access stratum (AS) and non-access stratum (NAS) signaling

In a method and a system for providing secure communication in a cellular radio system radio base station key is generated by determining a set of data bits known to both the UE and the radio base station, and creating the radio base station key in response to the determined set of data.

The present invention relates to a method and apparatus for requesting scheduling of resources to be used for uplink communication of data in a communications system. If the repeated transmission by a user equipment of scheduling requests on an uplink control channel is determined to be unsuccessful, a random access transmission on a random access channel is initiated as a fallback procedure.

Method and arrangement in a telecommunications system

A method () for use in a user terminal () in a cellular communications system (). According to the method, the user terminal applies a first timing advance value () to its transmissions to a controlling node (), and the user terminal () requests communication with the controlling node () in a contention based procedure by transmitting an access request (MSG), in response () to which the controlling node transmits an initiation message (MSG) along with () a second timing advance value. According to the method (), the user terminal () uses () the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

Timing alignment in an LTE system

Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.

Methods and arrangements in radio communication systems

An Uplink control channel resource Management Module (), referred to as 'UMM', and a method in the UMM for assigning, to a radio network node, uplink control channel resources, referred to as 'UCCHR', for use in a uplink control channel between the radio network node () and a communication device () are provided. The UMM obtains () resource allocation information, referred to as &#x201c;RAI&#x201d;, and generates () a resource allocation command, referred to as &#x201c;RAC&#x201d;, based on the RAI. The RAC indicates UCCHR to be used by the radio network node. Furthermore, the UMM provides () the RAC to the radio network node (). Related methods and nodes to enable the UMM to assign UCCHR are also provided.

Methods and arrangements in a radio communication system

There is provided a method for use in a user equipment when the user equipment is in idle mode or any other low activity state, and when the user equipment bandwidth is smaller than the cell transmission bandwidth. The method comprises the steps of determining a paging position of the user equipment in the frequency domain; receiving, from the network, paging information within the user equipment reception bandwidth; and changing, if indicated by the network, the paging position of the user equipment within the cell transmission bandwidth.

Method and arrangement in a telecommunication system

A radio access network comprises a donor base station node () and a relay base station node (). The relay base station node () participates in communications across a first radio interface with a wireless terminal () and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node () configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

HARQ handling at relay node reconfiguration

A technique for handling radio link failure in a communication network () is provided. A method implementation of this technique comprises the steps of maintaining radio link failure information including the identifier of a user equipment (UE) effected by the radio link failure together with at least one of a time stamp of when the radio link failure was detected and a reference to a cell (C) which was serving the user equipment (UE) before the radio link failure was detected, receiving reconnection information including an identifier of a reconnected user equipment (UE) effected by a radio link failure after the user equipment (UE) is reconnected to the communication network and correlating the radio link failure information with the reconnection information to obtain a correlation result.

Technique for handling radio link failure in a communication network

A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

Method and apparatus in a wireless communications system

The present invention relates to a method and to a transceiver () for detecting HARQ transmission failure in a telecommunications system. The transceiver () is arranged to execute a HARQ process which is used to generate a transmission of data units to e.g. a eNodeB. The transceiver is also arranged to determine when a maximum number of transmission attempts is reached and when this occurs to flush a HARQ buffer associated with the HARQ process and to detect that a HARQ transmission failure has occurred when the last HARQ feedback received for the current HARQ process is not a HARQ ACK.

Method and a transceiver for HARQ failure detection

A method and mobile terminal for providing uplink scheduling information to a scheduler in a wireless telecommunication system. When a logical channel having data available to transmit triggers a buffer status report, the mobile terminal determines whether a priority level associated with the logical channel exceeds a predefined threshold. If so, the mobile terminal performs a scheduling request procedure with the scheduler. If not, the mobile terminal delays the scheduling request procedure until a predefined timing event has occurred. The predefined timing event may be at least one of expiration of a timer, a radio bearer associated with the logical channel becoming active, and if the scheduling request procedure is being performed using a contention-based random access, contention resolution succeeding for the mobile terminal.

Method and mobile terminal providing priority-based uplink scheduling information

Uplink transmission scheduling requests (SRs) may be prohibited for a lower priority data flow, logical channel group (e.g., VoIP configured with semi-persistent resource allocation), or other grouping but may still be triggered for higher priority traffic (e.g., data connected to a signaling radio bearer (SRB)). More efficient scheduling is also achieved by allowing an uplink transmission scheduler to distinguish between different priority flows or groups (e.g., LCGs) without a buffer status report (BSR), As a result, when a semi-persistent resource is scheled for the lower priority data, there is less delay for high priority data while eliminating uplink and downlink control signaling, i.e., fewer scheduling requests (SRs) and uplink grants, for the lower priority data.
