摘要： A method (1000) for scheduling uplink transmission resources such as transmission duration and frequency to users (120) in a cell (110) of a cellular system (100). Grants for the use of uplink transmission resources are sent (1005) on a downlink control channel to users in the cell and the users' uplink transmissions are sent (1010) in subframes which have a certain extension in time and frequency. For each of at least a number of subframes, a decision (1015) is made on the number of users that will be scheduled resources for uplink transmission in the subframe, so that said number of users is maximized (1020) with respect to the control channel's capacity to transmit uplink grants for that subframe.

摘要： The embodiments herein relate to a method in a first network node (301 ) for handling Automatic Gain Control, AGC, scaling and Transmit Power Control, TPC, scaling of a signal received from a second network node (305). The first network node AGC compensates the signal for any AGC scaling changes. The AGC compensating the signal results in an AGC compensated signal comprising a constant AGC scaling. The first network node detects a TPC scaling change of the signal. The detection is based on the signal after the TPC scaling change and based on a predicted channel estimate. The predicted channel estimate is based on the signal before the TPC scaling change. The first network node TPC compensates for the detected TPC scaling change. The TPC compensation results in an AGC and TPC compensated signal comprising the constant AGC scaling and a constant TPC scaling according to the detected TPC scaling change.

摘要： The present invention describes an orthogonal frequency-division multiplexing, OFDM, transmitter and a method for embedding phase reference symbols into an OFDM symbol. The invention comprises a single-carrier pre-processing unit arranged to receive phase reference symbols and provide pre-processed phase reference samples as output and an OFDM modulator arranged to receive data symbols and the pre-processed phase reference samples as input and map the data symbols to sub-carriers and embed the single-carrier samples into a frequency sub-band of the OFDM symbol. While the invention particularly relates to an OFDM communication system, it should be noted that it could be applicable to any type of multicarrier communication system.
