Publication number: 20230292305Abstract: A method for configuring transmission order of uplink data, the method performed by a radio equipment (“RE”) of an access node. The RE has a RE controller (“REC”)-RE interface that communicatively couples the RE with a REC of the access node. The method includes receiving instructions from the REC that indicate a scheduling prioritization for transmission by the RE of uplink data between the RE and the REC over the REC-RE interface. The uplink data can be received by the RE on the radio interface. The method can further include transmitting the uplink data on the REC-RE interface according to the instructions, resulting in the scheduling prioritization of the uplink data.Type: ApplicationFiled: May 16, 2023Publication date: September 14, 2023Inventors: Jan ROXBERGH, Jacob ÖSTERLING, Christer ÖSTBERG, Henrik RONKAINEN

Patent number: 11632139Abstract: In mobile communications networks, requirements on signal distortion may be fulfilled at a lower bit rate, or alternatively quantization noise be reduced for a given bit rate, by including fractional exponent bits in a block floating point format. One or more fractional exponent bits may apply to all samples in the block. Alternatively, fractional bits may apply to sub-blocks within the block. The optimal number of fractional bits depends on the number of samples in the block.Type: GrantFiled: December 28, 2018Date of Patent: April 18, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Miguel Berg, Chenguang Lu, Daniel Cederholm, Jan Roxbergh, Fredrik Huss

Patent number: 10820334Abstract: There are provided mechanisms for configuring resolution of uplink data. An exemplary radio equipment controller (REC) of an access node includes an interface (RCE-RE interface) to a radio equipment (RE) and processing circuitry. The processing circuitry is configured to cause the REC to provide instructions to the RE regarding a resolution in time and/or frequency domain with which beam direction reports are to be transmitted to the REC on the REC-RE interface. The beam direction reports are based on uplink appointed reference symbols for sounding received by the RE on a radio interface and is to be transmitted from the RE to the REC. The REC may thus configure the resolution of the beam direction reports that are received by the REC.Type: GrantFiled: September 9, 2019Date of Patent: October 27, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Christer Östberg, Henrik Ronkainen, Jan Roxbergh, Henrik Olson
