Apparatus and method for wireless communication, and non-transitory computer readable medium storing program

A method for a base station, the method comprising:

• receiving, from a first wireless terminal, a first group identifier indicating a first terminal group;
• and
• allocating, to the first wireless terminal, a second radio resource, rather than a first radio resource, for transmitting a device-to-device (D2D) communication signal to a wireless terminal associated with the first terminal group, wherein
• the first radio resource is a radio resource which has already been allocated by the base station to a second wireless terminal which has sent the first group identifier to the base station, the first radio resource is used by the second wireless terminal to transmit a D2D communication signal to a wireless terminal associated with the first terminal group, and
• the second radio resource is a radio resource which has already been allocated by the base station to a third wireless terminal which has sent to the base station a second group identifier indicating a second terminal group different from the first terminal group, the second radio resource is used by the third wireless terminal to transmit a D2D communication signal to a wireless terminal associated with the second terminal group.

A non-transitory computer readable medium storing a program for causing a computer to perform a method for a base station, wherein the method comprises:

• receiving, from a first wireless terminal, a first group identifier indicating a first terminal group;
• and
• allocating, to the first wireless terminal, a second radio resource, rather than a first radio resource, for transmitting a device-to-device (D2D) communication signal to a wireless terminal associated with the first terminal group, wherein
• the first radio resource is a radio resource which has already been allocated by the base station to a second wireless terminal which has sent the first group identifier to the base station,
• the first radio resource is used by the second wireless terminal to transmit a D2D communication signal to a wireless terminal associated with the first terminal group, and
• the second radio resource is a radio resource which has already been allocated by the base station to a third wireless terminal which has sent to the base station a second group identifier indicating a second terminal group different from the first terminal group, the second radio resource is used by the third wireless terminal to transmit a D2D communication signal to a wireless terminal associated with the second terminal group.
