Publication number: 20240147362Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving communications between a user equipment (UE) and a base station in a shared radio frequency spectrum while the UE is operating in a discontinuous reception (DRX) mode. In particular, the UE may be configured to adapt operation in a DRX mode based on whether a base station has access to a shared radio frequency spectrum. For example, the UE may adjust a length of an on-duration for monitoring for a data transmission from the base station, adjust a periodicity for monitoring for control information from the base station, determine whether to keep monitoring for wake-up signaling from the base station, etc. based on whether the base station has access to the shared radio frequency spectrum. Further techniques for improving operation in a DRX mode are also described.Type: ApplicationFiled: November 4, 2020Publication date: May 2, 2024Inventors: Ananta Narayanan THYAGARAJAN, Sreekanth DAMA, Tanumay DATTA, Kapil BHATTAD, Xiaoxia ZHANG, Jing SUN, Ozcan OZTURK, Shashidhar VUMMINTALA, Gowrisankar SOMICHETTY, Pravjyot Singh DEOGUN, Ahmed ZAKI

Patent number: 11700586Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.Type: GrantFiled: July 8, 2021Date of Patent: July 11, 2023Assignee: Qualcomm IncorporatedInventors: Ayan Sengupta, Alberto Rico Alvarino, Le Liu, Gowrisankar Somichetty, Xiao Feng Wang, Wanshi Chen

Patent number: 11076427Abstract: Techniques are described for handling collisions between uplink transmissions and downlink transmissions over a wireless spectrum. Some of the techniques allow a UE to perform a collision management procedure after identifying a transmission collision (e.g., a collision between a downlink transmission with repetition and an uplink transmission, or a collision between a downlink transmission with repetition and a guard frame for an uplink transmission). The collision management procedure allows the UE to refrain from transmitting at least part of an uplink transmission, refrain from decoding at least part of a downlink transmission, or a combination thereof. Other techniques allow a base station to mitigate transmission collisions by scheduling downlink transmissions based on received, inferred, or determined parameters of uplink transmissions.Type: GrantFiled: November 21, 2017Date of Patent: July 27, 2021Assignee: QUALCOMM IncorporatedInventors: Vijayvaradharaj Tirucherai Muralidharan, Gowrisankar Somichetty, Shashidhar Vummintala, Vivek Padi, Kapil Bhattad, Alberto Rico Alvarino, Peng Liu

Patent number: 11050483Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.Type: GrantFiled: June 26, 2019Date of Patent: June 29, 2021Assignee: QUALCOMM IncorporatedInventors: Arvind Sridharan, Kapil Bhattad, Manikandan Chandrasekar, Gowrisankar Somichetty, Alberto Rico Alvarino, Xiao Feng Wang

Patent number: 11032028Abstract: Aspects of the disclosure relate to techniques for mitigating the decoding errors observed at the receiver as a result of puncturing symbols between consecutive subframes having the same transmission direction. To reduce the decoding errors, a plurality of transmission options, each including a number of resource blocks and a modulation and coding scheme (MCS), may be identified. In addition, each transmission option may be associated with one or more puncturing patterns that hinder decoding of a codeword at the receiver. The base station or user equipment (UE) may then select or modify at least one aspect of a scheduling decision involving the communication of the codeword in a given subframe of at least two consecutive subframes to minimize decoding errors. For example, a selected puncturing pattern or a transport block size associated with a selected transmission option may be modified.Type: GrantFiled: January 2, 2020Date of Patent: June 8, 2021Assignee: QUALCOMM IncorporatedInventors: Vijayvaradharaj Tirucherai Muralidharan, Gowrisankar Somichetty, Shashidhar Vummintala, Kapil Bhattad, Dominique Francois Bressanelli
