Abstract
A method for wireless communication at UE and related apparatus are provided. In the method, the UE groups a set of RBs of a slot into multiple PRGs having multiple PRG sizes; and communicates with a network entity based on multiple precoding matrices respectively associated with the multiple PRGs having the multiple PRG sizes. The UE performs a precoding procedure based on the multiple PRG sizes to obtain the multiple precoding matrices, and each precoding matrix of the multiple precoding matrices is based on a concatenated channel matrix based on a corresponding PRG size of the multiple PRG sizes.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to cause the UE to:
- group a set of resource blocks (RBs) of a slot into multiple physical resource block groups (PRGs) having multiple PRG sizes;
- perform, based on the multiple PRG sizes, a precoding procedure to obtain multiple precoding matrices for an uplink transmission with a network entity, wherein each precoding matrix of the multiple precoding matrices is based on a concatenated channel matrix based on a corresponding PRG size of the multiple PRG sizes;
- and
- communicate with the network entity based on the multiple precoding matrices respectively associated with the multiple PRGs having the multiple PRG sizes.
