Abstract
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for a simplified technique for a first sidelink device to discover another sidelink device. In some aspects, initial beam conformance between the first and second sidelink devices is established by the discovery. In some aspects, the first and second sidelink devices may be sidelink-capable UEs.

A method of wireless communications by a first sidelink device, comprising:
- transmitting a discovery sequence during a first slot of one or more first slots, wherein the discovery sequence is a sequence orthogonal to base sequences used for sidelink communications;
- receiving, from a second sidelink device during an associated second slot, a discovery reply sequence, wherein the associated second slot is a first number of slots later than the first slot, and wherein the discovery reply sequence is associated with an indication of acceptance of service with the second sidelink device in response to the discovery sequence;
- and
- transmitting, in response to the indication of acceptance, sidelink control information comprising a repeater configuration indicating one or more resources for the second sidelink device to forward signals from a network entity to the first sidelink device.
A method of wireless communications by a second sidelink device, comprising:
- receiving, from a first sidelink device, a discovery sequence during one or more first slots, wherein the discovery sequence is a sequence orthogonal to base sequences used for sidelink communications;
- transmitting a discovery reply sequence during an associated second slot, wherein the associated second slot is a first number of slots later than a first slot, of the one or more first slots, via which the discovery sequence is received,
- wherein the discovery reply sequence includes an indication of acceptance of service with the second sidelink device;
- and
- receiving, in response to the indication of acceptance, sidelink control information comprising a repeater configuration indicating one or more resources for the second sidelink device to forward signals from a network entity to the first sidelink device.
An apparatus for wireless communications by a first sidelink device, comprising:
- one or more processors and one or more memories, wherein the one or more processors and the one or more memories are configured to:
- transmit a discovery sequence during a first slot of one or more first slots, wherein the discovery sequence is a sequence orthogonal to base sequences used for sidelink communications;
- receive, from a second sidelink device during an associated second slot, a discovery reply sequence, wherein the associated second slot is a first number of slots later than the first slot, and wherein the discovery reply sequence is associated with an indication of acceptance of service with the second sidelink device in response to the discovery sequence;
- and
- transmit, in response to the indication of acceptance, sidelink control information comprising a repeater configuration indicating one or more resources for the second sidelink device to forward signals from a network entity to the first sidelink device.
An apparatus for wireless communications by a second sidelink device, wherein the apparatus includes one or more processors and one or more memories, wherein the one or more processors and the one or more memories are configured to:
- receive, from a first sidelink device, a discovery sequence during one or more first slots, wherein the discovery sequence is a sequence orthogonal to base sequences used for sidelink communications;
- transmit a discovery reply sequence during an associated second slot, wherein the associated second slot is a first number of slots later than a first slot, of the one or more first slots, via which the discovery sequence is received,
- wherein the discovery reply sequence includes an indication of acceptance or an indication of rejection of service with the second sidelink device;
- and
- receive, in response to the indication of acceptance, sidelink control information comprising a repeater configuration indicating one or more resources for the second sidelink device to forward signals from a network entity to the first sidelink device.
