Abstract
Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).
Claims20
An apparatus of a user equipment (UE), the apparatus comprising:
- processing circuitry, wherein the processing circuitry is configured to:
- receive a configuration by higher layers of at least first and second sets of physical uplink control channel (PUCCH) resources for transmitting uplink control information (UCI);
- select a PUCCH resource from the at least first and second sets of PUCCH resources for transmission of UCI based on an implicit rule, wherein the implicit rule comprises selecting the PUCCH resource based on a total number of UCI bits to be transmitted;
- and
- when the selected PUCCH resource corresponds to a first PUCCH format, set transmission power for transmitting the UCI using the selected PUCCH resource based at least on a parameter provided by higher layers corresponding to the first PUCCH format, a number of resources blocks of the selected PUCCH resource, and a total number of UCI bits;
- and
- memory coupled to the processing circuitry, wherein the memory is configured to store the UCI.

A user equipment (UE), comprising:
- a radio;
- processing circuitry coupled to the radio, wherein the processing circuitry is configured to:
- receive a configuration by higher layers of at least first and second sets of physical uplink control channel (PUCCH) resources for transmitting uplink control information (UCI);
- select a PUCCH resource from the at least first and second sets of PUCCH resources for transmission of UCI based on an implicit rule, wherein the implicit rule comprises selecting the PUCCH resource based on a total number of UCI bits to be transmitted;
- and
- when the selected PUCCH resource corresponds to a first PUCCH format, set transmission power for transmitting the UCI using the selected PUCCH resource based at least on a parameter provided by higher layers corresponding to the first PUCCH format, a number of resources blocks of the selected PUCCH resource, and a total number of UCI bits;
- and
- memory coupled to the processing circuitry, wherein the memory is configured to store the UCI.
5 more elements
A method for operating a user equipment (UE), the method comprising:

- selecting a PUCCH resource from the at least first and second sets of PUCCH resources for transmission of UCI based on an implicit rule, wherein the implicit rule comprises selecting the PUCCH resource based on a total number of UCI bits to be transmitted;
- and
- when the selected PUCCH resource corresponds to a first PUCCH format, setting transmission power for transmitting the UCI using the selected PUCCH resource based at least on a parameter provided by higher layers corresponding to the first PUCCH format, a number of resources blocks of the selected PUCCH resource, and a total number of UCI bits;
- and
- storing the UCI in memory.
