Method for transmitting control information in wireless communication system and apparatus therefor
Abstract
A method for transmitting information data by using a Reed-Muller coding scheme in a wireless communication system is disclosed. The method includes configuring a number of resource elements for transmitting the information data; dividing the information data to first information data and second information data if a bit size O of the information data is equal to or larger than a predetermined number; applying RM coding on each of the first information data and the second information data; concatenating the coded first information data and the coded second information data, and transmitting the concatenated data by using the predetermined number of resource elements, wherein a minimum value Q′ min for the number of resource elements is defined by a sum of a minimum value Q′ min_1 for the number of resource elements corresponding to the first information data and a minimum value Q′ min_2 for the number of resource elements corresponding to the second information data.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A method for transmitting uplink control information (UCI) at a user equipment in a wireless communication system, the method comprising:
dividing the UCI into a first sub-UCI and a second sub-UCI, a bit size (O) of the UCI equal to or larger than a predetermined number;
encoding each of the first sub-UCI and the second sub-UCI by using a Reed-Muller (RM) coding scheme;
concatenating the encoded first sub-UCI and the encoded second sub-UCI; and
transmitting the concatenated first sub-UCI and second sub-UCI to a base station using modulation symbols,
wherein a number of the modulation symbols is determined based on O,
wherein a minimum number (Q′ min ) of the modulation symbols is defined by a sum of a minimum number of the modulation symbols corresponding to the first sub-UCI (Q′ min_1 ) and a minimum number of the modulation symbols corresponding to the second sub-UCI (Q′ min_2 ),
wherein Q′ min_1 and Q′ min_2 are defined by using the following Equations:

,
where Q m indicates a bit size per modulation symbol.
2. The method of claim 1 , wherein the concatenated first sub-UCI and second sub-UCI transmitted via a Physical Uplink Shared Channel (PUSCH).
3. The method of claim 1 , wherein the predetermined number corresponds to 12 bits.
4. A user equipment (UE) of a wireless communication system, the UE comprising:
a processor configured to:
divide uplink control information (UCI) into a first sub-UCI and a second sub-UCI, to;
encode each of the first sub-UCI and the second sub-UCI by using a Reed-Muller (RM) coding scheme, and to concatenate the encoded first sub-UCI and the second sub-UCI, wherein a bit size (O) of the UCI is equal to or larger than a predetermined number; and
concatenate the encoded first sub-UCI and the second sub-UCI; and
a transmitter configured to transmit the concatenated first sub-UCI and second sub-UCI using modulation symbols to a base station,
wherein a number of the modulation symbols is determined based on O,
wherein a minimum number (Q′ min ) of the modulation symbols is defined by a sum of a minimum number of the modulation symbols corresponding to the first sub-UCI (Q′ min_1 ) and a minimum number of the modulation symbols corresponding to the second sub-UCI (Q′ min_2 ),
wherein Q′ min_1 and Q′ min_2 are defined by using the following Equations:

where Q m indicates a bit size per modulation symbol.
5. The UE of claim 4 , wherein the concatenated first sub-UCI and second sub-UCI transmitted via a Physical Uplink Shared Channel (PUSCH).
6. The UE of claim 4 , wherein the predetermined number corresponds to 12 bits.
7. The method of claim 1, wherein the UCI comprises a rank indicator (RI) or an acknowledgement/negative-acknowledgement (ACK/NACK).
8. The user equipment of claim 4, wherein the UCI comprises a rank indicator (RI) or an acknowledgement/negative-acknowledgement (ACK/NACK).Join the waitlist — get patent alerts
