Patent number: 11595176Abstract: Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme.

Patent number: 11582690Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status.

Patent number: 11582829Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. Aspects described herein provide techniques and apparatuses associated with synchronizing a preconfigured uplink resource (PUR) release counter between a base station and a user equipment (UE). For example, the synchronization may be performed in connection with the UE entering a connected mode, the base station reconfiguring a PUR, and/or the like. By synchronizing the PUR release counter, misalignment of the PUR release counter between the UE and the base station may be reduced or eliminated. Reducing the misalignment of the PUR release counter reduces the occurrence of a premature release of a PUR, thus reducing UE interference and improving the likelihood of success of the UE's transmission.Type: GrantFiled: October 29, 2020Date of Patent: February 14, 2023Assignee: QUALCOMM INCORPORATEDInventors: Umesh Phuyal, Mungal Singh Dhanda, Alberto Rico Alvarino, Le Liu, Ayan Sengupta
