摘要： The present invention relates to methods and apparatuses (radio base station and UE) for enabling a UE to perform a contention-based random access. According to embodiments of the present invention, a non-dedicated random access preamble identifier is determined by a radio base station (120, 400) and the determined preamble is transmitted in a message to the UE (110, 500) which selects a non-dedicated random access preamble based on the received preamble identifier and performs a contention-based random access using the selected preamble.

摘要： In a method and a device for requesting Channel Quality Indication (CQI) reports from a mobile station of a cellular radio system, the CQI reports are requested in response to a measured Block Error Rate (BLER) of transmissions from the mobile station. In accordance with one embodiment of the present invention a CQI report is requested if the BLER of the mobile station is above a predetermined threshold value C. The threshold value C can be set to a value related to the BLER target. In particular the value C can be set to the same value or as a value close the BLER that is targeted to try to adapt the CQI report request to how well the base station knows the channel. It can also be set higher or lower to also consider how much CQl reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

摘要： The present invention relates to a method and to a transceiver (400) for detecting HARQ transmission failure in a telecommunications system. The transceiver (400) 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.

摘要： 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 scheduled 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.

摘要： A method implemented at a user equipment (UE) may include receiving a grant from a base station permitting the user equipment to transmit data to the base station and transmitting data to the base station, where the data includes a buffer status report (BSR) that indicates an amount of data in a buffer of the UE. The method may further include starting or restarting a discontinuous reception (DRX) timer when the data including the BSR is transmitted to the base station. The method may additionally include monitoring (730) a control channel during a duration of the DRX timer. In another implementation, a method may include receiving a feedback message in response to the data transmission including the BSR, and starting or restarting the discontinuous reception (DRX) timer when the feedback message is received. The feedback message may include an acknowledgement (ACK) or a negative acknowledgement (NACK). In a further implementation, a method may include starting a process specific hybrid automatic repeat request (HARQ) round trip time (RTT) timer upon transmission of the data including the BSR, starting a grant timer when the HARQ RTT timer expires, and monitoring the control channel during a duration of the grant timer.

摘要： A method is provided for determining a location of a mobile device (130) in a wireless network. The method includes receiving global navigation satellite system (GNSS) (141-144) measurements from the mobile device, and receiving terrestrial measurements from corresponding transceivers (111-114) in the wireless network, each terrestrial measurement indicating a distance between the corresponding transceivers and the mobile device. The method further includes selecting at least one terrestrial measurement having an uncertainty value within a predetermined accuracy threshold. The location of the mobile device is determined as a function of the GNSS measurements and the selected terrestrial measurement.

摘要： The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.

摘要： 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.

摘要： Techniques for controlling synchronous HARQ retransmissions are disclosed, in which non-adaptive retransmissions scheduled for a first transmission time interval are automatically deferred to a later transmission time interval in the event that a control message prohibiting the retransmission during the first transmission interval is received. In an exemplary method, a NACK message is received (320) in response to a previous data transmission corresponding to a stop-and-wait HARQ process, and a synchronous HARQ retransmission is scheduled (330) for a first transmission interval in response. A control message indicating that data for the stop-and-wait HARQ process may not be sent during the first transmission interval is received, and the synchronous HARQ retransmission is automatically deferred (350) to a second transmission interval, responsive to the control message. An explicit grant is not required to trigger the retransmission during the second transmission interval.
