Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a set of reference signals to a first wireless node; receive information identifying a transmit power capability of the first wireless node based at least in part on transmitting the set of reference signals; and configure one or more transmission parameters for a first link with the first wireless node or a second link with a second wireless node based at least in part on the transmit power capability of the first wireless node. Numerous other aspects are provided.
Claims20
A method of wireless communication performed by a parent integrated access and backhaul (IAB) node, comprising:
- transmitting, to a child IAB node, a plurality of repetitions of a set of reference signals;
- receiving, from the child IAB node, a report of a set of channel quality measurements based at least in part on the transmission of the plurality of repetitions;
- and
- selecting a receive beam, of a plurality of receive beams for receiving communications from the parent IAB node, that corresponds to a reference signal based at least in part on the report and the plurality of repetitions of the set of reference signals to enable receipt of an uplink transmission from the child IAB node,
- the child IAB node being associated with a first link, of a plurality of links between the parent IAB node and a plurality of wireless devices associated with the plurality of links.
A parent integrated access and backhaul (IAB) node for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit, to a child IAB node, a plurality of repetitions of a set of reference signals;
- receive, from the child IAB node, a report of a set of channel quality measurements based at least in part on the plurality of repetitions;
- and
- select a receive beam, of a plurality of receive beams for receiving communications from the parent IAB node, that corresponds to a reference signal based at least in part on the report and the plurality of repetitions of the set of reference signals to enable receipt of an uplink transmission from the child IAB node,
- the child IAB node being associated with a first link, of a plurality of links between the parent IAB node and a plurality of wireless devices associated with the plurality of links.
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 parent integrated access and backhaul (IAB) node, cause the parent IAB node to:
- transmit, to a child IAB node, a plurality of repetitions of a set of reference signals;
- receive, from the child IAB node, a report of a set of channel quality measurements based at least in part on the plurality of repetitions;
- and
- select a receive beam, of a plurality of receive beams for receiving communications from the parent IAB node, that corresponds to a reference signal based at least in part on the report and the plurality of repetitions of the set of reference signals to enable receipt of an uplink transmission from the child IAB node,
- the child IAB node being associated with a first link, of a plurality of links between the parent IAB node and a plurality of wireless devices associated with the plurality of links.
A parent integrated access and backhaul (IAB) node for wireless communication, comprising:
- means for transmitting, to a child IAB node, a plurality of repetitions of a set of reference signals;
- means for receiving, from the child IAB node, a report of a set of channel quality measurements based at least in part on the transmission of the plurality of repetitions;
- and
- means for selecting a receive beam, of a plurality of receive beams for receiving communications from the parent IAB node, that corresponds to a reference signal based at least in part on the report and the plurality of repetitions of the set of reference signals to enable receipt of an uplink transmission from the child IAB node,
- the child IAB node being associated with a first link, of a plurality of links between the parent IAB node and a plurality of wireless devices associated with the plurality of links.
