CPC H04L 5/0051 (2013.01) | 18 Claims |
1. A base station (BS), comprising:
radio front end circuitry; and
processor circuitry, coupled to the radio front end circuitry, and configured to:
determine a first transmission configuration indicator (TCI) state corresponding to the BS, wherein the BS is a first transmission reception point (TRP) and a second TCI state corresponds to a second TRP;
determine a demodulation reference signal (DMRS) port indication value that correlates a first DMRS port of the first TRP to the first TCI state and a second DMRS port of the second TRP to the second TCI state,
wherein the DMRS port indication value indicates a number of code division multiplexing (CDM) groups and correlates: a first CDM group of the number of CDM groups with the first DMRS port, and a second CDM group of the number of CDM groups with the second DMRS port and with a third DMRS port, wherein the second DMRS port and the third DMRS port transmit on different layers; and
transmit, using the radio front end circuitry, a single downlink control information (DCI) signal comprising: the first TCI state, the second TCI state, and the DMRS port indication value.
