Abstract

[Object] To provide a mechanism that enables flexible design in relation to communication timing. [Solution] A communication apparatus including: a communication control unit that controls transmission of any one of a first channel that is transmitted in a first direction and a second channel that is transmitted in a second direction that faces the first direction and corresponds to the first channel and reception of the other one of the first channel and the second channel; and a setting unit that sets a control mode of the communication control unit to a first mode or a second mode. The communication control unit transmits and receives the first channel and the second channel in different sub frames in the first mode and transmits and receives the first channel and the second channel in a same sub frame in the second mode.

Claims18

Dependent claims

A communication method performed by a terminal device, the method comprising:

receiving control information and a shared channel,
wherein the shared channel is a downlink shared channel from a base station or a sidelink shared channel from another terminal device;
setting a switching parameter based on the control information;
receiving setting information from radio resource control signaling for setting a control mode of the terminal device to a first mode or a second mode;
according to the set control mode, transmitting an uplink channel corresponding to the shared channel,
wherein the uplink channel is an uplink channel to the base station or the sidelink shared channel;
and
based on the control mode having been set to the second mode:
comparing the switching parameter to a predetermined threshold,
wherein the switching parameter comprises a number of resource blocks allocated to the shared channel;
based on the switching parameter being larger than the predetermined threshold, switching the control mode from the second mode to the first mode;
and
transmitting the uplink channel corresponding to the shared channel according to the first mode,
wherein a processing time of the terminal device after receiving the shared channel in the first mode is longer than the processing time of the terminal device after receiving the shared channel in the second mode.
