Terminal apparatus with offset determined depending on subframe set
A terminal apparatus communicates with a base station apparatus. The terminal apparatus includes: a determination unit that determines the number of modulation symbols for channel state information transmitted on a physical uplink shared channel based on a value of an offset; and a transmission unit that transmits the channel state information to the base station apparatus on the physical uplink shared channel. When two subframe sets are configured by higher layers, the value of the offset is determined depending on the subframe set to which subframes for transmission on the physical uplink shared channel belong. Thus, the communication can be performed efficiently in a radio communication system in which the channel state information is used.
1. A terminal apparatus comprising:
reception circuitry that receives, from a base station apparatus, a higher layer message at least indicating two uplink subframe sets, the higher layer message not indicating a value of an offset;
determination circuitry that determines a number of modulation coded symbols for a channel quality indicator based on the value of the offset; and
transmission circuitry that transmits the channel quality indicator to the base station apparatus on a physical uplink shared channel in a subframe,
wherein the determination circuitry determines the value of the offset based on one of the two uplink subframe sets to which the subframe for transmission of the channel quality indicator on the physical uplink shared channel belongs.
2. A terminal apparatus comprising:
reception circuitry that receives, from a base station apparatus, a higher layer message at least indicating a first uplink subframe set and a second uplink subframe set, the higher layer message not indicating a value of an offset;
configuration circuitry that configures the first uplink subframe set and the second uplink subframe set by the higher layer message;
determination circuitry that determines a number of modulation coded symbols for a channel quality indicator based on the value of the offset; and
transmission circuitry that transmits the channel quality indicator to the base station apparatus on a physical uplink shared channel in a subframe,
wherein the determination circuitry configures a first value as the value of the offset for the subframe, and
the determination circuitry configures a second value in place of the first value as the value of the offset for the subframe in a case that the subframe belongs to the second uplink subframe set.
3. The terminal apparatus according to claim 1 , wherein
the higher layer message indicates whether a subframe belongs to a first subframe set or a second subframe set.
4. The terminal apparatus according to claim 2 , wherein
the higher layer message indicates whether a subframe belongs to a first subframe set or a second subframe set.
