摘要： A method for configuring gain factors in a WCDMA telecommunication system is provided in which the gain factor for defining power required for normal reception of uplink data in an environment supporting an uplink service over an E-DCH can be configured using minimal signaling information. First gain factors for first TFs corresponding to a part of a TF set including a plurality of TFs available for an uplink service are received. One of the first TFs is determined as a reference TF for a second TF other than the first TFs in the TF set. Then, a second gain factor for the second TF is calculated using the first gain factor for the determined reference TF. The second gain factor is used for transmitting or receiving uplink data.

摘要： Embodiments of the present disclosure are directed toward devices and methods for fast radio link recovery in cellular networks. In one embodiment, the signal strength of the serving cell is compared to the signal strength of a target cell, and a radio link failure (RLF) timer is terminated or shortened based on the comparison. Alternatively, a second shorter timer may be used as opposed to modifying the current timer. In some embodiments, the modification of RLF timers may be triggered by the start of a measurement trigger timer. This may allow a user equipment to more quickly establish a connection with a target cell in situations where radio link failure or handover failure are likely to occur. In some instances, the parameters for terminating or shortening the radio link failure timer, or starting an additional timer, may be provided to the user equipment by a network.

摘要： Technology for enabling radio resource management (RRM) measurements in coordinated multi-point (CoMP) transmission and reception is disclosed. One method comprises sending, from an evolved node B (eNB) to a user equipment (UE), an information element (IE) containing a list of measurement objects that define configurations of channel state information reference signal (CSI-RS) based RRM measurements. The eNB can analyze the CSI-RS based RRM measurements in a CoMP Resource Management (CRM) Set, wherein each CSI-RS based RRM measurement corresponds to a transmission point in a set of transmission points which may be used for downlink transmissions to the UE. The eNB can select a CoMP Measurement Set based on the CSI-RS based RRM measurements reported by the UE, comprising at least one of the set of transmission points for which fast channel state information (CSI) feedback will be reported to the eNB from the UE.
