AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in efficiently supporting uplink communications, particularly in applying orthogonal cover code (OCC) sequences to physical uplink shared channel (PUSCH) transmissions due to issues like unavailable resources, repetitions, and overlapping with other channels.

Method used

The method involves a user equipment (UE) receiving information about available resources for uplink communications and applying an OCC sequence to PUSCH transmissions. The UE determines the mapping between elements of the OCC sequence and PUSCH transmissions based on the received information, adjusting for unavailable resources and repetitions.

Benefits of technology

This approach enables efficient multiplexing of uplink communications by effectively managing resource availability and sequence application, thereby improving the throughput and reliability of wireless communication systems.

Abstract

Various aspects of the present disclosure relate to a method and apparatus of supporting uplink communications. An exemplary method performed by a UE may include: receiving first information indicating whether one or more resources are available for uplink; receiving second information indicating application of an OCC sequence to a set of PUSCH transmissions; and determining mapping between elements of the OCC sequence and the set of PUSCH transmissions or a subset of PUSCH transmissions of the set of PUSCH transmissions based on the first information and the second information.
