摘要： Disclosed herein is a system and method for downlink beamforming that takes into account imperfect channel state information (CSI) at the transmitter when determining the steering vector used in the beamforming process. The steering vector is calculated to increase the ratio of the 5 average power of a desired signal component to the sum of the interference power of other wireless terminals, referred to as the signal-to-leakage ratio. By accounting for imperfect CSI when calculating the steering vector, the bit-error rate for a given signal-to-noise ratio is decreased. Also disclosed is a power allocation method that improves performance of the system by increasing the signal-to-interference-plus-noise ratio for all of the wireless terminals currently communicating with 10 the base station. The power allocation similarly decreases the bit-error rate for a given signal-to- noise ratio, especially at high signal-to-noise ratios.

摘要： Methods and systems for dynamically activate and deactivate an allocated resource for a UE to make grant-free uplink transmission are provided. In one embodiment, a user equipment (UE) receives a Radio Resource Control (RRC) signal. The RRC signal specifies grant-free (GF) configuration information. The GF configuration information comprises an activation field and at least one other GF resource configuration field. The activation field indicates whether the UE may perform GF uplink (UL) transmissions without waiting for a downlink control information (DCI) message. Then, the UE performs a GF UL transmission in accordance with the GF configuration information in the RRC signal.
