Transmitting apparatus, receiving apparatus and radio communication method
A terminal is disclosed including a receiver that receives downlink control information indicating a transmission bandwidth allocated to a downlink shared channel within a bandwidth part, and a processor that determines a size of a precoding resource block group (PRG), to which a same precoding is applied, based on the transmission bandwidth or a subset of the transmission bandwidth. In other aspects, a radio communication method for a terminal is also disclosed.
1. A terminal comprising:
a receiver that receives downlink control information indicating a transmission bandwidth allocated to a downlink shared channel within a bandwidth part; and
a processor that determines a size of a precoding resource block group (PRG), to which a same precoding is applied, based on the transmission bandwidth or a subset of the transmission bandwidth,
wherein the processor does not expect that the transmission bandwidth includes non-contiguous resource blocks,
wherein the processor determines the size of the PRG based on a number of resource blocks included in the bandwidth part, and
wherein the PRG includes one or more resource blocks.
2. A radio communication method for a terminal comprising:
receiving downlink control information indicating a transmission bandwidth allocated to a downlink shared channel within a bandwidth part; and
determining a size of a precoding resource block group (PRG), to which a same precoding is applied, based on the transmission bandwidth or a subset of the transmission bandwidth,
wherein the terminal does not expect that the transmission bandwidth includes non-contiguous resource blocks,
wherein the terminal determines the size of the PRG based on a number of resource blocks included in the bandwidth part, and
wherein the PRG includes one or more resource blocks.
3. A base station comprising:
a transmitter that transmits downlink control information indicating a transmission bandwidth allocated to a downlink shared channel within a bandwidth part; and
a processor that determines a size of a precoding resource block group (PRG), to which a same precoding is applied, based on the transmission bandwidth or a subset of the transmission bandwidth,
wherein the processor does not expect that the transmission bandwidth includes non-contiguous resource blocks,
wherein the processor determines the size of the PRG based on a number of resource blocks included in the bandwidth part, and
wherein the PRG includes one or more resource blocks.
4. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives downlink control information indicating a transmission bandwidth allocated to a downlink shared channel within a bandwidth part; and
a first processor that determines a size of a precoding resource block group (PRG), to which a same precoding is applied, based on the transmission bandwidth or a subset of the transmission bandwidth,
the base station comprises:
a transmitter that transmits the downlink control information; and
a second processor that determines the size of the PRG, to which the same precoding is applied, based on the transmission bandwidth or the subset of the transmission bandwidth,
wherein the first processor does not expect that the transmission bandwidth includes non-contiguous resource blocks,
wherein the first processor determines the size of the PRG based on a number of resource blocks included in the bandwidth part, and
wherein the PRG includes one or more resource blocks.
