摘要： Embodiments of techniques and systems for quality of experience (QoE) reporting in wireless systems are described. In some embodiments, user equipment may receive a first value of a first quality of experience (QoE) metric computed during playout of a multimedia asset at the user equipment. The first value may be received at a first layer in a protocol stack of the user equipment from a second layer above the first layer in the protocol stack. The user equipment may provide a first layer report, including data representative of the first value, for wireless transmission from the user equipment to an eNB. Other embodiments may be described and claimed.

摘要： A method for estimating a channel from received signals transmitted via the channel, includes the steps of receiving the received signals with receiving sensors of a receiving device. The received signals are composed of a plurality of subscriber signals. The subscriber signals are marked with transmitter-specific fine structures. A subscriber signal of the plurality of subscriber signals is transmitted by a plurality of wave elements having differing incidence directions at a receiving point. An incidence direction of at least one of the wave elements is obtained in the receiving device. Directionally selective channel impulse responses are determined from the plurality of received signals and the incidence direction of the at least one wave element.
