Abstract: A technique for operating a wireless communication device includes transmitting a scheduling request from the wireless communication device and receiving, following the scheduling request, an uplink grant that assigns an uplink channel to the wireless communication device. The uplink grant may include one or more fields indicating whether only channel quality information is to be transmitted or if data is also to be transmitted.

Abstract: Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.

Abstract: Embodiments of the disclosure provide a system and method for providing channel feedback information (CFI) from a user equipment device to a base station. CFI is transmitted from the user equipment device on first and second communication channels. The user equipment device is operable to measure the channel rank of a downlink channel and to select a preferred channel rank that is used to configure the CFI that is transmitted to the base station. The base station is operable to use the preferred channel rank to interpret the CFI transmitted by the user end device.

Abstract: A multi-user MIMO downlink beamforming system with limited feedback (200) is provided to enable precoding for multi-stream transmission, where a channel codeword (ui) and one or more channel quality indicator values (CQIA, CQIB) are computed at the user equipment (201.i) on the basis of maximizing a predetermined SINR performance metric (?i) which estimates the receive signal-to-noise-ratio (SINR) at the user equipment (201.i). The computed codeword (ui) and CQI values (or differential values related thereto) are quantized and fed back to help the base station (210) which applies a correction to the appropriate CQI value in the course of designing the transmit beamforming vectors w and determining the appropriate modulation and coding level to be used for downlink data transmission.
