Abstract
Aspects of the disclosure relate to mechanisms for mapping a physical downlink control channel (PDCCH) across multiple transmission configuration indication (TCI) states. In some examples, the PDCCH may then be encoded using a common mother polar code for each of a first set of control channel elements (CCEs) mapped to a first TCI state and a remaining set of CCEs mapped to a second TCI state. First and second portions of the encoded PDCCH may then be transmitted, such that the first portion includes the first set of CCEs, and the second portion includes the remaining set of CCEs.
