USER EQUIPMENT SHIFT RANDOMIZATION FOR UPLINK CONTROL CHANNEL TRANSMISSION - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18209262 Titled 'USER EQUIPMENT SHIFT RANDOMIZATION FOR UPLINK CONTROL CHANNEL TRANSMISSION'
Simplified Explanation
The abstract describes methods, systems, and devices for wireless communications. It explains that randomized shifts of a base sequence can be used to transmit uplink control information. A user equipment (UE) can identify a base sequence and receive signaling indicating a UE-specific initial shift to be applied to the base sequence. The signaling for the randomized shift can be explicit, implicit, or a combination of both. The UE then determines shifted sequences based on the initial shift, payload of the uplink control message, and the base sequence. The UE selects a shifted sequence to transmit based on the payload of the uplink control message. Different shifted sequences can be selected for different types of transmissions, such as scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and more.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. In some cases, randomized shifts of a base sequence may be used for transmitting uplink control information. For example, a user equipment (UE) may identify a base sequence of an uplink control message. The UE may also receive signaling that indicates a UE-specific initial shift that may be applied to the base sequence. In some examples, the signaling that indicates the randomized shift may be explicit, implicit, or a combination thereof. After determining one or more shifted sequences based on the UE-specific initial shift, a payload of the uplink control message, and the base sequence, the UE may select a shifted sequence to be transmitted, where the selection is based on a payload of the uplink control message. For example, different shifted sequences may be selected for respective transmissions of scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and the like.
