Patent number: 11923991Abstract: Certain aspects of the present disclosure provide techniques for dynamic configuration of demodulation reference signals (DMRSs). A method that may be performed by a base station (BS) includes receiving one or more uplink signals from at least one user equipment (UE); estimating a Doppler shift associated with the one or more uplink signals; determining a density of reference signals (RSs) within a slot for the at least one UE based, at least in part, on the estimated Doppler shift associated with the one or more uplink signals; and transmitting information to the at least one UE indicating an allocation of RS resources for the UE, wherein the allocation of the RS resources is based on the density of the RSs for the at least one UE.Type: GrantFiled: November 24, 2020Date of Patent: March 5, 2024Assignee: QUALCOMM IncorporatedInventors: Satish Kumar, Siva Naga Raju Undrakunta, Harika Lavanuru, Sarath Pinayour Chandrasekaran, Loksiva Paruchuri, Ashok Kumar Tripathi, Raja Sekhar Bachu

Patent number: 11576203Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, based at least in part on a configuration of a first random access channel associated with a macro cell, one or more parameters of a configuration of a second random access channel associated with a small cell provided by the base station. The base station may transmit an indication of the one or more parameters of the configuration of the second random access channel. Numerous other aspects are provided.Type: GrantFiled: November 19, 2020Date of Patent: February 7, 2023Assignee: QUALCOMM IncorporatedInventors: Satish Kumar, Loksiva Paruchuri, Ashok Kumar Tripathi

Publication number: 20220272628Abstract: Certain aspects of the present disclosure provide techniques for power saving through discontinuous reception (DRX) in multiple subscriber identity module (multi-SIM) user equipment (UE). A method that may be performed by a UE includes determining a first DRX configuration associated with a first SIM and a second DRX configuration associated with a second SIM are asynchronous, generating, based on the first DRX configuration and the second DRX configuration, a synchronous DRX configuration for communicating with the first SIM and the second SIM, transmitting, to a first base station (BS) associated with the first SIM and to a second BS associated with the second SIM, an indication of the synchronous DRX configuration, and communicating with the first BS using the first SIM and the second BS using the second SIM in accordance with the synchronous DRX configuration.Type: ApplicationFiled: February 23, 2021Publication date: August 25, 2022Inventors: Sudeepta Kumar NATH, Ashok Kumar TRIPATHI, Anil Kumar DEVPURA, Tushar SINGH, Gagana Sindhu SABBAVARAPU, Sowmya PENTA

Patent number: 11424851Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU) located at a base station. The O-DU may communicate with the O-RU using control messaging, and the O-DU may signal whether various resource block groups are used for data allocation by enabling or disabling bits in a bit mask parameter in a header of the control message. To increase communications efficiency and reduce overhead, the O-DU may dynamically configure the number of bits included in a bit mask based on a radio access technology (RAT) type. The O-DU may determine the size of the bit mask in the control message based on the RAT type and may generate the control message that includes the bit mask.Type: GrantFiled: December 9, 2020Date of Patent: August 23, 2022Assignee: QUALCOMM IncorporatedInventors: Sudeepta Kumar Nath, Tushar Singh, Ashok Kumar Tripathi, Anil Kumar Devpura, Loksiva Paruchuri, Satish Kumar
