Patent number: 11722287Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify multiple regions within a subframe, such as one or more uplink regions, one or more downlink regions, and a guard region. The wireless device may identify and communicate during each region based on a timing relationship between the downlink region and the uplink region. For example, the device may expect hybrid automated repeat request (HARQ) feedback for one downlink region in the same subframe based on the proximity to the next uplink region. Another downlink region may not have HARQ feedback in the same subframe. Similarly, uplink regions may or may not be scheduled within the same subframe.Type: GrantFiled: June 22, 2016Date of Patent: August 8, 2023Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Shimman Arvind Patel, Aleksandar Damnjanovic, Peter Gaal
