  • Patent number: 10511351
    Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

  • Patent number: 10499351
    Abstract: A controller having access to channel information associated with a neighboring access point (AP) may communicate a mask to a served user equipment (UE). The mask may specify transmission parameters for an uplink transmission between the served UE and a serving AP such that a successful decoding probability of the uplink transmission at the neighboring AP exceeds a threshold. The mask may specify a maximum MCS level for the uplink transmission, a minimum transmit power level for the uplink transmission, and/or a precoder constraint for the uplink transmission that produces constructive interference at a spatial location of the neighboring AP. This may enable the neighboring AP to isolate the uplink transmission from uplink wireless signals using an interference cancellation technique, e.g., successive interference cancellation (SIC) techniques.

  • Patent number: 10334535
    Abstract: A user equipment (UE) may compute uplink power control levels as a function of a downlink signal to noise ratio (SNIR). For example, the UE may determine an uplink transmit power level by summing a full power control (FPC) transmit power level, a product of a first adjustment factor (?) and the downlink SNIR, and a negative of a second adjustment factor (?2) when the product of the first adjustment factor (?) and the downlink SNIR is greater than or equal to the second adjustment factor (?2). A UE may also compute an uplink power control level as a function of target and/or current interference levels associated with neighboring base stations. A UE may also iteratively reduce a transmit power level until an interference level experienced by a neighboring base station has fallen below a threshold.
