1. A method for wireless communication at a first user equipment (UE), comprising:
receiving a configuration signal indicating a codebook construction configuration for constructing a codebook of sequences for conveying a first type of uplink payload in a resource block that is orthogonal to a second type of uplink payload transmitted from a second UE in the resource block;
constructing the codebook of sequences for the first type of uplink payload according to the codebook construction configuration;
generating the first type of uplink payload for transmission using a first sequence from the codebook of sequences; and
transmitting the first type of uplink payload in the resource block, wherein the first type of uplink payload is multiplexed in the resource block with the second type of uplink payload from the second UE,
wherein said constructing the codebook of sequences according to the codebook construction configuration comprises:
generating an orthogonal sequence pool by mapping resource elements associated with the orthogonal sequence pool in the physical domain to resource elements in a virtual domain;
constructing a virtual codebook of sequences according to the mapping;
converting uplink payload data into an integer corresponding to a first sequence from the virtual codebook of sequences;
mapping the first sequence to a plurality of virtual resource elements in the virtual domain; and
mapping the plurality of virtual resource elements in the virtual domain to a plurality of physical resource elements of the resource block in a physical domain for transmitting the first type of uplink payload in the resource block.
