Abstract
This base station is provided with: a control circuit that generates information relating to a terminal group among a plurality of terminals, said terminal group being a target of transmission by non-orthogonal multiple access; and a transmission circuit that transmits the information relating to the terminal group during a period in which control information addressed to the plurality of terminals is transmitted.
Claims13
A base station, comprising:
- control circuitry, which, in operation,
- generates information on a terminal group among a plurality of terminals, the terminal group being a target of transmission by non-orthogonal multiplexing, and
- generates a non-orthogonal multiplex access (NOMA) signal, wherein a length of the NOMA signal is determined based on a terminal with a lowest reception processing capability among the plurality of the terminals;
- and
- transmission circuitry, which, in operation, transmits the information on the terminal group during a period for transmitting common information for the plurality of terminals, wherein:
- the period for transmitting the common information for the plurality of terminals is during a period for transmitting control information addressed to the plurality of terminals, and
- the information on the terminal group is associated with some frequency resource candidate values among a plurality of frequency resource candidates in allocation information of a frequency resource indicated in the common information.
4 more elements
A terminal, comprising:
- reception circuitry, which, in operation,
- receives information on a terminal group among a plurality of terminals that is non-orthogonally multiplexed, during a period for receiving common information for the plurality of terminals, wherein the period for receiving the common information for the plurality of terminals is during a period for receiving downlink control information addressed to the plurality of terminals, and
- receives a non-orthogonal multiplex access (NOMA) signal, wherein a length of the NOMA signal is determined based on a terminal with a lowest reception processing capability among the plurality of the terminals;
- and
- control circuitry, which, in operation, controls reception of a downlink non-orthogonal multiplex signal based on the information on the terminal group,
- wherein the information on the terminal group is associated with some frequency resource candidate values among a plurality of frequency resource candidates in allocation information of a frequency resource indicated in the common information.
3 more elements
A communication method, comprising:
- generating, by a base station, information on a terminal group among a plurality of terminals, the terminal group being a target of transmission by non-orthogonal multiplexing;
- generating a non-orthogonal multiplex access (NOMA) signal, wherein a length of the NOMA signal is determined based on a terminal with a lowest reception processing capability among the plurality of the terminals;
- transmitting, by the base station, the information on the terminal group during a period for transmitting common information for the plurality of terminals, wherein the period for transmitting the common information for the plurality of terminals is during a period for transmitting control information addressed to the plurality of terminals;
- and
- transmitting the NOMA signal,
- wherein the information on the terminal group is associated with some frequency resource candidate values among a plurality of frequency resource candidates in allocation information of a frequency resource indicated in the common information.
3 more elements
A communication method, comprising:
- receiving, by a terminal, information on a terminal group among a plurality of terminals that is non-orthogonally multiplexed, during a period for receiving common information for the plurality of terminals, wherein the period for receiving the common information for the plurality of terminals is during a period for receiving downlink control information addressed to the plurality of terminals;
- receiving a non-orthogonal multiplex access (NOMA) signal, wherein a length of the NOMA signal is determined based on a terminal with a lowest reception processing capability among the plurality of the terminals;
- and
- controlling, by the terminal, reception of a downlink non-orthogonal multiplex signal based on the information on the terminal group,
- wherein the information on the terminal group is associated with some frequency resource candidate values among a plurality of frequency resource candidates in allocation information of a frequency resource indicated in the common information.
