Abstract: Systems and methods for transmission of full power uplink transmission in 5G networks are described. The gNB provides TPMI precoding information in DCI of a PDCCH in which the field size for precoding information and number of layers are fixed irrespective of the SRI. The gNB indicates in RRC signaling the use of codebook-based transmission for UL. If different SRS resources with different number of antenna ports are configured, the bitwidth of the SRI field is the maximum number of ports among the configured SRS resources in an SRS resource set with usage set to ‘codebook’. If the number of ports for a configured SRS resource in the set is less than the maximum number of ports, the most significant bits of the field have a value of ‘0’. The bitwidth is dependent on UE coherence capabilities and a maxrank of the UE.

Abstract: Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.

Abstract: An interference cancellation repeater employing zero-IF or direct conversion radio architecture implements IQ imbalance compensation using a metric and an adaptive algorithm. The metric is based on the image rejection ratio of the repeater and is indicative of the level of spectral image caused by the repeater's receiver or transmitter IQ imbalance.

Abstract: Systems and methodologies are described herein that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system. As described herein, a network device can measure and report interference corresponding to network nodes outside a designated set of nodes that can cooperatively serve the device. Respective interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of respective nodes, or the like. Subsequently, respective interference reports can be combined with per-node channel information to manage coordination and scheduling across respective network nodes. As further described herein, interference from a network node can be measured by observing reference and/or synchronization signals from the network node. To aid such observation, respective non-interfering network nodes can define null pilot intervals in which transmission is silenced or otherwise reduced.

Abstract: Closed-loop techniques for adjusting the duty cycle of a cyclical signal, e.g., a clock signal, to approach a target value. In an exemplary embodiment, a charge pump is coupled to a charge and sample module, which drives a de-skew circuit in a negative feedback loop.

The voltages across the sampling capacitors may be used to control the de-skew circuit, which adjusts the duty cycle of a cyclical signal to be adjusted.
