Abstract

Claims (38)

1. A first node for wireless communications, comprising:

a first receiver for receiving a first signaling and a second signaling; and

a first transmitter for transmitting a first radio signal in a first slot;

wherein:

the first signaling is used for indicating a first time window, an index for the first slot in the first time window being a first index, and the second signaling and a location of the first node are jointly used for determining a first time offset;

when the first radio signal is transmitted on a mainlink, the first index is used for generating the first radio signal;

when the first radio signal is transmitted on a sidelink, a second index is used for generating the first radio signal, the second index is related to both the first time offset and the first index.

2. The first node according to claim 1 , wherein the first transmitter is further for transmitting a second radio signal which indicates a second time window, and an index for the first slot in the second time window is the second index.

3. The first node according to claim 2 , wherein the first transmitter is further for transmitting a third radio signal which indicates a first time-frequency resource pool in the second time window.

4. The first node according to claim 1 , wherein the first receiver is further for receiving a third signaling which indicates a first reference time offset value set used for determining the first time offset.

5. The first node according to claim 1 , wherein the first receiver is further for receiving a fourth signaling which indicates a second time offset used to determine the first time offset.

6. The first node according to claim 1 , wherein a difference between the second index and the first index is equal to the first time offset.

7. A second node for wireless communications, comprising:

a second transmitter for transmitting a first signaling and a second signaling; and

a second receiver for receiving a first radio signal in a first slot;

wherein:

the first signaling is used for indicating a first time window, an index for the first slot in the first time window being a first index, and the second signaling and a location of a first node are jointly used for determining a first time offset;

when the first radio signal is transmitted on a mainlink, the first index is used for generating the first radio signal; and

when a transmitter for the first radio signal transmits the first radio signal on a sidelink, a second index is used for generating the first radio signal, the second index being related to both the first time offset and the first index.

8. The second node according to claim 7 , wherein the second transmitter is further for transmitting a third signaling indicates a first reference time offset value set used for determining the first time offset.

9. The second node according to claim 7 , wherein the second transmitter is further for transmitting a fourth signaling which indicates a second time offset used to determine the first time offset.

10. A third node for wireless communications, comprising:

a third receiver for receiving a first radio signal in a first slot, a second radio signal indicating a second time window, and a third radio signal indicating a first time-frequency resource pool in the second time window, where an index for the first slot in the second time window is a second index; and

a third transmitter for transmitting a fourth radio signal in time-frequency resources in the first time-frequency resource pool,

wherein:

a first signaling is used for indicating a first time window, an index for the first slot in the first time window being a first index, and a second signaling is used for determining a first time offset;

when a transmitter for the first radio signal transmits the first radio signal on a mainlink, the first index is used for generating the first radio signal;

when the first radio signal is transmitted on a sidelink, the second index is used for generating the first radio signal, the second index being related to both the first time offset and the first index; and

a reception timing for a synchronization signal transmitted by a synchronization reference source determined by the third node is used to determine a transmission timing for the fourth radio signal.

11. A third node for wireless communications, characterized in comprising:

a third receiver for receiving a first radio signal in a first slot, a second radio signal indicating a second time window, and a third radio signal indicating a first time-frequency resource pool in the second time window, where an index for the first slot in the second time window is a second index; and

a third transmitter for transmitting a fifth radio signal in time-frequency resources in the first time-frequency resource pool,

wherein:

a first signaling is used for indicating a first time window, an index for the first slot in the first time window being a first index, and a second signaling is used for determining a first time offset;

when a transmitter for the first radio signal transmits the first radio signal on a mainlink, the first index is used for generating the first radio signal;

when the first radio signal is transmitted on a sidelink, the second index is used for generating the first radio signal, the second index being related to both the first time offset and the first index;

the first radio signal is used to determine a transmission timing for the fifth radio signal, and

a transmitter for the first radio signal is different from a synchronization reference source determined by the third node.
