Beamformed channel busy ratio

A method of wireless communication performed by a user equipment (UE), comprising:

• measuring, for a first beam group of a set of beam groups associated with the UE, a first channel busy ratio (CBR) for the first beam group;
• receiving, from a second UE, an indication of a second CBR that is based at least in part on a measurement performed by the second UE, the second CBR being for a second beam group associated with the second UE;
• and
• transmitting, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR, wherein the one or more transmit parameters include at least one of:
• a number of hybrid automatic repeat request retransmissions,
• a number of subchannels to be used by the UE in a slot,
• a modulation and coding scheme, or
• a channel occupancy ratio limit.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• measure, for a first beam group of a set of beam groups associated with the UE, a first channel busy ratio (CBR) for the first beam group;
• receive, from a second UE, an indication of a second CBR that is based at least in part on a measurement performed by the second UE, the second CBR being for a second beam group associated with the second UE;
• and
• transmit, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR, wherein the one or more transmit parameters include at least one of:
• a number of hybrid automatic repeat request retransmissions,
• a number of subchannels to be used by the UE in a slot,
• a modulation and coding scheme, or
• a channel occupancy ratio limit.

An apparatus for wireless communication, comprising:

• means for measuring, for a first beam group of a set of beam groups associated with the apparatus, a first channel busy ratio (CBR) for the first beam group;
• means for receiving, from a user equipment (UE), from a second UE, an indication of a second CBR that is based at least in part on a measurement performed by the second UE, the second CBR being for a second beam group associated with the second UE;
• and
• means for transmitting, to the UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR, wherein the one or more transmit parameters include at least one of:
• a number of hybrid automatic repeat request retransmissions,
• a number of subchannels to be used by the UE in a slot,
• a modulation and coding scheme, or
• a channel occupancy ratio limit.
