摘要： A measuring node (700) in a wireless network (100) sets switching points for a plurality of measurement groups, performs measurements of signals transmitted from one or more cells corresponding to a group, and switches, at each switching point, from performing measurements according to one measurement group to performing measurements according to the next measurement group. The signals are transmitted by the cells in measurement occasions that repeat in a pattern. A switching point is a time by which the measuring node (700) node is expected to complete, at least in part, measurements of the one group and be ready to proceed with measurements of the next group. A configuring node (600) sends assistance data to the measuring node (700) to enable the measuring node (700) to determine the switching points for the measurement groups.

摘要： A network node determines one or more parameters related to a Specific Absorption Rate (SAR) target, where SAR is a measure of a maximum energy or power absorbed by a unit of mass of tissue exposed to radio frequency (RF) electromagnetic field (EMF) radiation generated as a result of radio transmissions generated by a UE. The network node generates content for a message for transmission to the UE including the determined one or more SAR-related parameters to be applied by a transmitter in the UE. Based on those one or more SAR-related parameters, the UE determines and implements an action in order to meet the SAR target. Other example embodiments permit the UE to determine the SAR-related parameters in other ways.

摘要： Methods (100) and apparatuses (12, 24, 38) taught herein advantageously facilitate use of timing measurements in wireless communication networks (10) where radio signal timing measurements involve signals at different carrier frequencies. The methods and apparatuses in particular compensate such timing measurements for expected discrepancies in the measurements that arise from frequency-dependent differences in the propagation behavior of the radio signals being measured. In a non-limiting example, measurements at two or more frequencies may be compensated for the frequency distance between those frequencies, or with respect to a reference frequency. In such cases, timing measurements determined for one or more other radio signals are compensated as a function of the frequency distance between the reference frequency and the frequencies of such other radio signals.

摘要： The invention relates to methods and arrangements for an event triggered DRX cycle adjustment. A user equipment located in a serving cell of a mobile communications network monitors downlink communication at predetermined time intervals when operating in discontinuous reception mode. The user equipment also performs communication parameter measurements regarding at least one of the serving cell and one or more neighbor cells. After the occurrence of a first event, the user equipment sends at least one of measurement data and a first event report to the network. The sending is triggered by the occurrence of the first event. The monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein the second event is defined to indicate a higher probability of receiving a handover command than the first event.

摘要： The present disclosure relates to a technique for avoiding, forestalling, or reducing re-establishment procedures in a telecommunications system having multiple carriers. A method aspect of this technique includes monitoring a signal quality of an anchor component carrier associated with a serving cell of a mobile terminal and used by the mobile terminal. If the signal quality of the anchor component carrier violates a first signal quality condition, then a parameter (of, e.g., a downlink signal) of at least one candidate component carrier associated with the serving cell and distinct from the anchor component carrier is measured and the signal quality of the at least one candidate component carrier is determined based on the measured parameter. If the determined signal quality fulfils a second signal quality condition, then reselection to the at least one candidate component carrier is initiated such that the candidate component carrier becomes the anchor component carrier associated with the serving cell and used by the mobile terminal.

摘要： The present invention relates to methods and devices for mobility management UE in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.
