Abstract

A WTRU may be configured to efficiently utilize redundant resources in a first resource set by transmitting, in a second resource set, a larger number of reference symbols. The WTRU also may report CSIs with a lower code-rate. Based on association rules that provide an indication for utilizing redundant resources, the WTRU may efficiently utilize redundant resources by replacing zero padded bits in the first resource set with transmission parameters in the second resource set. Based on the association rules, the WTRU may dynamically determine a DMRS configuration, a code-rate, a modulation and coding scheme (MCS), and/or CSI quantization parameters.

Claims20

Dependent claims

A wireless transmit/receive unit (WTRU) comprising:

a transceiver;
and
a processor configured to:
receive, via the transceiver, configuration information, the configuration information comprising first uplink transmission parameters, a first uplink resource set, second uplink transmission parameters, a second uplink resource set, and an indication of association rules;
determine a size of a first channel state information (CSI) payload and a size of a second CSI payload;
based on a determination that the size of the first CSI payload is less than the size of the second CSI payload, determine third uplink transmission parameters based on the association rules;
send, via resources indicated by the first uplink resource set, a first uplink transmission using the first uplink transmission parameters, wherein the first uplink transmission comprises the first CSI payload;
and
send, via resources indicated by the second uplink resource set, a second uplink transmission using the third uplink transmission parameters, wherein the second uplink transmission comprises the second CSI payload.
