Patent number: 11770835Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configured grant that indicates time-frequency resources for a user equipment (UE) to use to transmit sidelink or uplink messages in a wireless communications system. To reduce the amount of low priority traffic that may interfere with higher priority traffic, the base station may configure a threshold probability to allow high priority sidelink transmissions and to cancel low priority transmissions. The base station may transmit a cancellation indication that includes a priority indication instructing the UE to cancel transmissions having a priority less than a priority threshold during the allocated time-frequency resources. Based on transmitting the cancellation indication, the base station may cancel transmissions that have low priority, and the UE may determine whether to transmit (or to refrain from transmitting) one or more messages based on the priority of the message.Type: GrantFiled: February 25, 2021Date of Patent: September 26, 2023Assignee: QUALCOMM IncorporatedInventors: Jung Ho Ryu, Sony Akkarakaran, Tao Luo, Junyi Li, Ling Ding, Jelena Damnjanovic, Juan Montojo, Kapil Gulati

Patent number: 11751249Abstract: Methods, systems, and devices for wireless communication are described. For a user equipment with a number of M greater than or equal to two antennas, a signal is transmitted from at least a first antenna and a second antenna at a first time with an initial relative phase state including a first relative phase rotation between the signals transmitted by the first and second antennas. In response to a determination that a response signal was not received at the user equipment, the signal is retransmitted from at least the first antenna and the second antenna with a subsequent relative phase state among the transmitting antennas, including a second different relative phase rotation, at a second time.
