Patent number: 11611973Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times. The processor then receives from the network a grant. In response to receiving the grant, the processor performs the UL transmission to the network. In transmitting the request for the plurality of times, the processor transmits the request for the plurality of times at a frequency higher than a frequency at which the request to perform UL transmissions is transmitted to the network when the apparatus is in a normal operational mode.Type: GrantFiled: June 30, 2021Date of Patent: March 21, 2023Inventors: Chiao-Chih Chang, Chien-Liang Lin, Jen-Hao Hsueh, Cheng-Che Chen, Sheng-Yi Ho, I-Wei Tsai, Zhen Jiang, Wen-Jean Yang
