Abstract

A relay wireless transmit/receive unit (WTRU) may receive a data transmission from a target WTRU. The data transmission from the target WTRU may be or may include an implicit indication that the target WTRU is unable to listen for a message directed to the target WTRU. The message directed to the target WTRU may be a broadcast preemption message (BPM) and may be transmitted from a source WTRU. Based on the reception of the data transmission from the target WTRU, the relay WTRU may determine that the target WTRU is unable to listen for the BPM. Based on the determination, the relay WTRU may monitor for the BPM. The relay WTRU may receive and decode the BPM. The relay WTRU may determine whether to relay the BPM in a message, such as a broadcast relay message (BRM). The relay WTRU may transmit the BRM to the target WTRU.

Dependent claims

A first wireless transmit/receive unit (WTRU) comprising:

a processor configured to:
determine, based on reception by the first WTRU of a data transmission from a second WTRU, that the second WTRU is unable to listen for a first message directed to the second WTRU;
monitor for the first message directed to the second WTRU based on the determination;
receive the first message directed to the second WTRU;
determine whether to relay the first message to the second WTRU in a second message;
and
if the first WTRU determines to relay the first message to the second WTRU, transmit the second message to the second WTRU;
wherein the first message comprises a broadcast preemption message to the second WTRU to skip transmitting on a resource;
and
wherein to determine whether to relay the first message to the second WTRU, the processor is configured to:
decode the first message, wherein the first message is transmitted from a source WTRU;
determine one or more of a number of times that the first message has been relayed, a time stamp indicative of when the first message has been transmitted from a third WTRU, or a distance between the third WTRU and the first WTRU;
and
transmit the first message to the second WTRU in the second message, the second message comprising information about one or more of the number of times that the first message has been relayed, the time stamp associated with when the first message has been transmitted from the third WTRU, or the distance between the third WTRU and the first WTRU.

A method performed by a first wireless transmit/receive unit (WTRU) comprising:

determining, based on reception by the first WTRU of a data transmission from a second WTRU, that the second WTRU is unable to listen for a first message directed to the second WTRU;
monitoring for the first message directed to the second WTRU based on the determination;
receiving the first message directed to the second WTRU;
determining whether to relay the first message to the second WTRU in a second message;
and
if the first WTRU determines to relay the first message to the second WTRU, transmitting the second message to the second WTRU;
wherein the first message comprises a broadcast preemption message to the second WTRU to skip transmitting on a resource;
and
wherein determining whether to relay the first message to the second WTRU comprises:
decoding the first message, wherein the first message is transmitted from a source WTRU;
determining one or more of a number of times that the first message has been relayed, a time stamp indicative of when the first message has been transmitted from a third WTRU, or a distance between the third WTRU and the first WTRU;
and
transmitting the first message to the second WTRU in the second message, the second message comprising information about one or more of the number of times that the first message has been relayed, the time stamp associated with when the first message has been transmitted from the third WTRU, or the distance between the third WTRU and the first WTRU.

A first wireless transmit/receive unit (WTRU) comprising:

a processor configured to:
determine, based on reception of a data transmission from a second WTRU by the first WTRU, that the second WTRU is unable to listen for a first message directed to the second WTRU to obtain a first determination result;
monitor for the first message directed to the second WTRU based on the first determination result;
receive the first message directed to the second WTRU;
determine whether to relay the first message to the second WTRU in a second message;
and
if the first WTRU determines to relay the first message to the second WTRU, transmit the second message to the second WTRU,
wherein, to determine whether to relay the first message to the second WTRU in the second message, the processor is configured to:
decode the first message, wherein the first message comprises a broadcast preemption message to the second WTRU to skip transmitting;
determine whether one or more of a number of times that the first message has been relayed exceeds a preconfigured relay counter threshold, a time stamp indicative of when the first message has been transmitted from a third WTRU exceeds a preconfigured time threshold, or a distance between the third WTRU and the first WTRU exceed a preconfigured distance threshold, to obtain a second determination result;
and
skip transmitting the second message to the second WTRU based on the second determination result.
