摘要： Control channel information is formulated for transmission in orthogonal frequency division multiplexing (OFDM) systems. In an example embodiment, a method entails formulating control channel information for a transmitting device operating in an OFDM system in which a control channel spans n OFDM symbols, with n being an integer. The method includes acts of allocating, creating, and mapping. Control channel data is allocated to at least one set of resource element groups. At least one order for the set of resource element groups is created in accordance with one or more permutation mechanisms that involve at least one interleaving sequence having a low cross-correlation property. The set of resource element groups is mapped to resource elements of the n OFDM symbols of the control channel responsive to the order that is created using the permutation mechanism(s). The permutation mechanisms may include interleaving sequence(s) and/or cyclic shift(s).

摘要： A base station is described herein which implements a method that uses different aspects of reported channel quality information (CQI) measurements to help select the "best" transmit antenna(s) on which to transmit control channel information to mobile terminal(s). The base station can also transmit a format indicator to communicate the assigned control channel transmit antenna(s) and the assigned data transmit antenna(s) to the mobile terminal(s).

摘要： Operating a user equipment in a mobile communication system includes generating a measure of reliability of a predicted channel estimate and of impairment stability, wherein the predicted channel estimate is a predicted estimate of a channel between the user equipment and a node of the mobile communications system. Transmission of a channel quality report to the node of the mobile communication system is controlled as a function of the generated measure of reliability of the predicted channel estimate and of impairment stability. Transmission control includes inhibiting transmission of the channel quality report to the node of the mobile communication system for a duration of time corresponding to the measure of reliability of the predicted channel estimate and of impairment stability.
