Disclosed is a method to operate a wireless user equipment, a wireless user equipment, a computer program product, and an apparatus. The method includes, in response to operation during a Baseline Procedure when no absolute grant (AG) is received from a wireless network node, determining if there was a scheduled transmission in a previous transmission time interval of a hybrid automatic repeat request (HARQ) process and, if there was, using a serving relative grant (SRG) and, if it is determined instead that there was not a scheduled transmission in the previous transmission time interval of the HARQ process, not using the SRG if it is determined that there was a scheduling information (SI) event alone in the previous transmission time interval of the HARQ process.

Apparatus, method and computer program product providing user equipment operation by considering scheduling information with regard to the use of relative grants

A transmitter is included in a mobile communication network. The transmitter is included configured to transmit to a receiver a data channel and a first control channel controlling data transmissions on the data channel, transmit, on the first control channel, an indicator indicating that there is data transmission to the receiver on the data channel. The transmitter also is configured to omit data transmission on the data channel.

Data transmission in mobile communication system

A receiver for use in a mobile communications network, the receiver comprising an input for receiving radio signals including control symbols and data symbols, a channel estimator arranged to use the control symbols to provide a channel estimate for correcting received data symbols, a first offset corrector for de-rotating the control symbols prior to their use in providing the channel estimate, a second offset corrector for rotating the channel estimate prior to its use in correcting the received data symbols, and an offset estimator arranged to generate estimates of frequency offset in the received radio signal, for use in the first and second offset correctors.
