Method and device in ue and base station for wireless communication

A method in a base station for wireless communication, comprising:

• transmitting a first signaling, the first signaling being used for indicating a first time-frequency resource pool and a first spatial parameter group, the first spatial parameter group being associated to the first time-frequency resource pool, and the first time-frequency resource pool comprising a first time-frequency resource set;
• transmitting a second signaling, the second signaling being used for indicating a second spatial parameter group;
• and
• monitoring a first radio signal in the first time-frequency resource set, or, giving up monitoring a radio signal in the first time-frequency resource set;
• wherein the first spatial parameter group and the second spatial parameter group are used for indicating whether the first time-frequency resource set can be used for transmitting a radio signal.

A UE for wireless communication, comprising:

• a first receiver, to receive a first signaling, the first signaling being used for indicating a first time-frequency resource pool and a first spatial parameter group, the first spatial parameter group being associated to the first time-frequency resource pool, and the first time-frequency resource pool comprising a first time-frequency resource set;
• a second receiver, to receive a second signaling, the second signaling being used for indicating a second spatial parameter group;
• and
• a third transmitter, to judge whether the first time-frequency resource set can be used for transmitting a radio signal;
• if so, to transmit a first radio signal in the first time-frequency resource set, an antenna port used for transmitting the first radio signal being related to the first spatial parameter group;
• otherwise, to give up transmitting a first radio signal in the first time-frequency resource set;
• wherein the first spatial parameter group and the second spatial parameter group are used for judging whether the first time-frequency resource set can be used for transmitting a radio signal.
