Patent number: 11979235Abstract: Certain aspects of the present disclosure provide techniques for relaying physical sidelink control channel in sidelink communications. A method that may be performed by a first user equipment (UE) includes receiving a sidelink control information (SCI) transmission from a second UE, the SCI pointing to one or more resources for a retransmission of the SCI by the second UE. The method may include transmitting the SCI to a third UE using the one or more resources for the retransmission of the SCI by the second UE.Type: GrantFiled: May 13, 2021Date of Patent: May 7, 2024Assignee: QUALCOMM IncorporatedInventors: Lior Uziel, Omri Netanel Mamo, Guy Wolf

Patent number: 11974223Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications. For example, a wireless communications system may support New Radio (NR) cellular-vehicle to everything (C-V2X) communication. In some examples, a user equipment (UE) may receive a sidelink control channel for a sidelink transmission on a first set of symbols of a time slot (e.g., the first two or three symbols of a time slot). The UE may decode the sidelink control channel and disable one or more radio frequency (RF) components associated with processing the sidelink transmission on a second set of symbols of the time slot based on decoding the sidelink control channel. For example, the UE may disable one or more RF components if the UE determines the sidelink control channel is decoded unsuccessfully.Type: GrantFiled: December 16, 2020Date of Patent: April 30, 2024Assignee: QUALCOMM IncorporatedInventors: Cheol Hee Park, Gideon Kutz, Shmuel Vagner, Lior Uziel, Moshe Ben-Ari

Patent number: 11936581Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.Type: GrantFiled: September 21, 2022Date of Patent: March 19, 2024Assignee: QUALCOMM IncorporatedInventors: Michael Levitsky, Assaf Touboul, Ran Berliner, Shay Landis, Lior Uziel

Publication number: 20240040506Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reconfiguring a resource envelope allocated to a distributed unit (DU) or a radio unit (RU) based on power consumption at the DU or the RU. A virtual radio access network (VRAN) manager (e.g., a host platform for a VRAN) may perform baseband pooling to allocate a resource envelope to a DU or an RU. After an initial allocation of a resource envelope to a DU or an RU, the DU, the RU, or both may report an amount of power consumed during signal processing for one or more dimensions of the resource envelope. The VRAN manager may then reconfigure a resource envelope for the DU or the RU based on the power consumption at these devices (e.g., to minimize operating expenses (OPEX) or maximize utilization of the resource envelope).Type: ApplicationFiled: July 29, 2022Publication date: February 1, 2024Inventors: Lior Uziel, Guy Wolf, Assaf Touboul

Publication number: 20240022939Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for dynamically adapting a baseband resource envelope (e.g., baseband resources) allocated to a network entity. A virtual radio access network (VRAN) manager (e.g., a host platform for a VRAN) may perform baseband pooling to allocate a baseband resource envelope to a network entity for signal processing at the network entity. The network entity may perform measurements indicating the channel conditions associated with communicating with one or more user equipment (UEs), and the network entity may report the measurements to the VRAN manager. The VRAN manager may then adapt a baseband resource envelope allocated to the network entity based on the measurements to improve the utilization of processing resources.Type: ApplicationFiled: July 18, 2022Publication date: January 18, 2024Inventors: Lior Uziel, Guy Wolf, Assaf Touboul
