摘要： The present disclosure discloses a pilot signal transmission method in a wireless communication system and an associated Transmit-Receive Point (TRP). The method comprises transmitting a periodic pilot signal for channel estimation from at least one TRP in the proximity of a User Equipment (UE) within a combined cell, when the UE is not scheduled for data transmission. The method further comprises transmitting a pilot signal for demodulation from the same TRP, when the UE is scheduled for data transmission. The transmission power of the periodic pilot signal for channel estimation is lower than that of the pilot signal for signal for channel demodulation. The present disclosure further provides a pilot signal reception method in a wireless communication network and an associated UE.

摘要： A method and arrangement are provided for determining a minimum value or range for a transmit power gain factor an enhanced uplink data channel, referred to as βed; min, that controls the transmit power level for the enhanced uplink data channel relative to the transmit power for the uplink control channel so as to ensure delivery of a minimum data service requirement over the enhanced uplink data channel. The minimum value or range for the enhanced uplink data channel power gain factor may be determined based on a selected enhanced uplink transmission format and/or a maximum number of allowable transmission attempts over the enhanced uplink data channel for a communications session so that the required Quality of Service (QoS) for the communications session can be fulfilled and an expected uplink coverage gain can be reached. The minimum value or range for the enhanced uplink data channel power gain factor is also compatible with other techniques to increase enhanced uplink coverage such as autonomous retransmission and improved L2 techniques.

摘要： A wireless terminal (30) comprises a communications interface (34) and a congestion controller (40). The communications interface (34) communicates over a radio interface (32) with a base station (28). The congestion controller (40), upon occurrence of a congestion indication, reduces uplink transmission power of the wireless terminal (30) by lowering a transport format combination for use by the wireless terminal for transmitting an enhanced dedicated uplink channel (E-DCH) over the radio interface to the base station (28). In an example embodiment and mode, the congestion controller (40) performs an expedited transport format combination reduction procedure which is distinct from Dedicated Physical Control Channel (DPCCH) power reduction based on a command received in a closed loop power control procedure, e.g., on a Fractional-DPCH (F-DPCH) channel.
