Publication number: 20250097948Abstract: Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.Type: ApplicationFiled: November 26, 2024Publication date: March 20, 2025Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Sung-Hyuk Shin, Pascal M.
