Abstract
A method of a transmit apparatus in a wireless communication system supporting ranging capability is provided. The method comprises: for a single-sided two-way ranging (SS-TWR), identifying a ranging round (RR) including a ranging initiation phase (RIP) for a set of transmit apparatuses including the transmit apparatus and a ranging response phase (RRP) for a set of receive apparatuses, wherein the RIP and the RRP comprise at least one slot; transmitting, to the set of receive apparatuses, a ranging initiation message in the RIP; and receiving, from one or more of the set of receive apparatuses, a ranging response message including information requested by the transmit apparatus in the RRP.
Claims20
A transmit apparatus in a wireless communication system supporting ranging capability, the transmit apparatus comprising:
- a processor configured to, for a single-sided two-way ranging (SS-TWR), identify a ranging round (RR) including a ranging initiation phase (RIP) for a set of transmit apparatuses including the transmit apparatus and a ranging response phase (RRP) for a set of receive apparatuses, wherein the RIP and the RRP comprise at least one slot;
- and
- a transceiver operably connected to the processor, the transceiver configured to:
- transmit, to the set of receive apparatuses, a ranging initiation message in the RIP;
- and
- receive, from one or more of the set of receive apparatuses, a ranging response message in the RRP, wherein the ranging response message includes information requested by the transmit apparatus.
A receive apparatus in a wireless communication system supporting ranging capability, the receive apparatus comprising:
- a transceiver configured to receive, from a transmit apparatus of a set of transmit apparatuses, a ranging initiation message in a ranging initiation phase (RIP);
- and
- a processor operably connected to the transceiver, the processor configured to, for a single-sided two-way ranging (SS-TWR), identify a ranging round (RR) including the RIP for a set of receive apparatuses including the receive apparatus to receive and a ranging response phase (RRP) for the set of transmit apparatuses to receive, the RIP and the RRP comprising at least one slot,
- wherein, the transceiver is further configured to transmit, to one or more of the set of transmit apparatuses, a ranging response message in the RRP, wherein the ranging response message includes information requested by the transmit apparatus.
A method of a transmit apparatus in a wireless communication system supporting ranging capability, the method comprising:
- for a single-sided two-way ranging (SS-TWR), identifying a ranging round (RR) including a ranging initiation phase (RIP) for a set of transmit apparatuses including the transmit apparatus and a ranging response phase (RRP) for a set of receive apparatuses, wherein the RIP and the RRP comprise at least one slot;
- transmitting, to the set of receive apparatuses, a ranging initiation message in the RIP;
- and
- receiving, from one or more of the set of receive apparatuses, a ranging response message in the RRP, wherein the ranging response message includes information requested by the transmit apparatus.
