摘要： Disclosed is a network node and a method performed by a network node in a wireless communication network for determining signal to noise ratio of a signal received at a receiver from a first mobile station, which signal may include both noise and interference. The method comprises obtaining a plurality of measured noise and interference power values, IN values, of signals received at the receiver in one or more frequency sub-bands, determining IN for a lowest X percentile of the measured IN values, and applying the determined IN for the lowest X percentile as a measure of the noise. The method further comprises obtaining a measured signal strength value for a signal received at the receiver from the first mobile station, and determining SNR for the signal from the first mobile station by applying the determined noise measure.

摘要： This disclosure deals with an arrangement in a base station (120) for controlling transmission of delay-sensitive data from a transmitter (1 12) over a transmission link in a packet data communication network, which transmitter is capable of changing between a TTI bundling enabled mode and a TTI bundling disabled mode. The arrangement comprises: a receiver (402) for receiving data from the transmitter over the transmission link; a decision unit (404) for deciding that the transmitter should change TTI bundling mode; a silent mode detection unit (406) for detecting that the transmitter is in a silent mode; and a triggering unit (408) for triggering change of TTI bundling mode in response to deciding that the transmitter should change TTI bundling mode and in response to detecting that the transmitter is in a silent mode. The disclosure further relates to a corresponding method.

摘要： It is presented a method for releasing semi-persistent scheduling, SPS, for a wireless device. The method is performed in a network node and comprising the steps of: transmitting an SPS release message to the wireless device to release uplink SPS; starting a timer; when a first condition is true, transmitting a grant for uplink transmission to the wireless device, the first condition being true when the timer expires and/or a scheduling request has been received from the wireless device; receiving a data type indication from the wireless device; and determining that an SPS release message has been correctly received by the wireless device when a scheduling request has been received from the wireless device, the grant has been transmitted and the data type indication indicates only voice over internet protocol, VoIP, data from the wireless device.

摘要： A method in a base station for handling a scheduling of a narrowband transmission from a user equipment in a cell served by the base station is provided. The base station and the user equipment are comprised in a cellular network. A time resource available for the scheduling is divided into available subframes. A frequency resource available for scheduling in each respective subframe is divided into available resource blocks. The base station selects a subframe among the subframes available for scheduling. Narrowband transmissions are to be prioritized for scheduling to the selected subframe. The base station schedules the transmission to a subset of the available resource blocks in the selected subframe when an indication that the transmission from the user equipment is a narrowband transmission is obtained.

摘要： The present invention sets forth a method and apparatus for estimating Doppler spread associated with a Rayleigh or fast fading channel established between a radio base station and a mobile radio station. In particular, the Doppler spread is estimated through calculation of the autocorrelation function of a sequence of complex channel estimates determined from a known sequence Pn in the received signal. More specifically, a sequence of complex channel estimates obtained from the known sequence in a first sampling interval is complex conjugated and then correlated with a sequence of complex channel estimates obtained from the known reference in a second sampling interval which have been not been complex conjugated. A zero crossing of the complex autocorrelation function is detected, and the estimated Doppler spread is calculated using this zero crossing and a Bessel function.
