Terminal and communication method
A terminal comprising a control circuit for controlling communications in units of a second symbol, each unit being associated with a plurality of first symbols, and a communication circuit for performing communications.
1 . A terminal, comprising:
control circuitry, which, in operation, controls communication in units of virtual symbols in a virtual slot, the virtual slot being composed of symbols in a plurality of slots, a total number of the virtual symbols in the virtual slot being equal to a total number of symbols in each of the plurality of slots, each of the virtual symbols including a plurality of consecutive symbols of the symbols in the plurality of slots associated in one unit, a signal in the plurality of consecutive symbols being subject to repetition;
communication circuitry, which, in operation, performs the communication; and
reception circuitry, which, in operation, receives information on a total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot, wherein
the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot for each of a plurality of types of channels used for the communication, and
the total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot differs for each of the plurality of types of channels.
2 . The terminal according to claim 1 , wherein the control circuitry controls communication in units of time durations each composed of a plurality of virtual symbols.
3 . The terminal according to claim 1 , wherein the information indicates one of a plurality of candidate numbers of symbols.
4 . The terminal according to claim 1 , wherein the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols for a downlink or an uplink.
5 . The terminal according to claim 1 , wherein the total number of the plurality of consecutive symbols composing each of the virtual symbols is a power of 2.
6 . The terminal according to claim 1 , wherein the total number of the plurality of consecutive symbols composing each of the virtual symbols is configured based on a number of the plurality of consecutive symbols composing a slot.
7 . The terminal according to claim 2 , wherein a number of the plurality of consecutive symbols composing one of at least two of the virtual symbols included in a time duration is different from a number of the plurality of consecutive first symbols composing another one of the at least two of the virtual symbols.
8 . The terminal according to claim 1 , wherein an upper limit value of the total number of the plurality of consecutive symbols composing each of the virtual symbols is smaller than a number of the plurality of consecutive symbols composing a slot.
9 . The terminal according to claim 1 , wherein the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols for each of a plurality of types of signals used for the communication.
10 . The terminal according to claim 1 , wherein the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols for each of a plurality of parameters for the terminal.
11 . The terminal according to claim 1 , wherein the total number of the plurality of consecutive symbols composing each of the virtual symbols for a first type of channel is different from the total number of the plurality of consecutive symbols composing each of the virtual symbols for a second type of channel.
12 . The terminal according to claim 1 , wherein
the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols for each of a first type of symbols and a second type of symbols, and
the total number of the plurality of consecutive symbols composing each of the virtual symbols for the first type of symbols is different from the total number of the plurality of consecutive symbols composing each of the virtual symbols for the second type of symbols.
13 . A communication method, comprising:
controlling, by a terminal, communication in units of virtual symbols in a virtual slot, the virtual slot being composed of symbols in a plurality of slots, a total number of the virtual symbols in the virtual slot being equal to a total number of symbols in each of the plurality of slots, each of the virtual symbols including a plurality of consecutive symbols of the symbols in the plurality of slots associated in one unit, a signal in the plurality of consecutive symbols being subject to repetition;
performing the communication by the terminal; and
receiving, by the terminal, information on a total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot, wherein
the information includes information on the total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot for each of a plurality of types of channels used for the communication, and
the total number of the plurality of consecutive symbols composing each of the virtual symbols in the virtual slot differs for each of the plurality of types of channels.
