Patent number: 11895593Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.Type: GrantFiled: March 8, 2022Date of Patent: February 6, 2024Assignee: QUALCOMM IncorporatedInventors: Manu Krishnan Kavunkal, Manav Lnu, Manish Jain, Abhishek Kumar, Venkata Pavan Kumar Bhargav Medepally, Kiran Singh Matharu, Parees Kambli, Awlok Singh Josan, Farrukh Rashid, Ashutosh Vinod Agrawal

Patent number: 11277192Abstract: A user equipment (UE) may monitor multiple beam pair links (BPLs) including a first BPL currently used by the UE to communicate with a network node (e.g., a base station), and a second BPL. The first BPL comprises a first network beam and a first UE beam, and the second BPL comprises a second network beam and a second UE beam. The UE may decide to switch beams from using the first BPL to using the second BPL based on signaling from the network node or autonomously. When the beam switch is made, the UE switches uplink (UL) transmission from over the first UE beam to over the second UE beam. After the beam switch is made, the UE transmits in the UL over the second UE beam using UL timing adjusted based on the first and second propagation delays.Type: GrantFiled: October 30, 2019Date of Patent: March 15, 2022Assignee: QUALCOMM IncorporatedInventors: Hongbo Yan, Raghu Narayan Challa, Guy Wolf, Michael Levitsky, Ran Berliner, Awlok Singh Josan

Patent number: 11272509Abstract: Methods, systems, and devices for wireless communications are described that provide for adjustment of an uplink timing at a user equipment (UE) based on switching a beamformed transmission beam used for communications between the UE and a base station. The UE and base station may establish a connection via a first beamformed transmission beam and an uplink timing of the first beamformed transmission beam may be determined. A timing difference between the first beamformed transmission beam and a second beamformed transmission beam may be identified and, in the event that communications are switched from the first beamformed transmission beam to the second beamformed transmission beam, the uplink timing may be adjusted based at least in part on the timing difference. Such uplink timing adjustment may be made autonomously at the UE, and may be made irrespective of a magnitude of the adjustment.Type: GrantFiled: August 7, 2019Date of Patent: March 8, 2022Assignee: QUALCOMM IncorporatedInventors: Awlok Singh Josan, Valentin Alexandru Gheorghiu
