Abstract
Systems, methods and instrumentalities are disclosed for beam-based PDCCH Transmission in NR. Control resource sets may be assigned for multi-beam control transmission. A PDCCH may be transmitted with multiple beams. CCEs may be mapped for multi-beam transmission. DCI may support multi-dimensional transmission with primary and secondary dimensions. Search space may support multi-beam, multi-TRP transmission.

1-15. (canceled)
A wireless transmit/receive unit (WTRU), the WTRU comprising:
- a processor, the processor configured to:
- determine a first set of control channel elements (CCEs), wherein the first set of CCEs is associated with a first beam and a first search space (SS), and wherein the first SS is associated with a first control resource set (CORESET);
- determine a second set of CCEs, wherein the second set of CCEs is associated with a second beam and a second SS, and wherein the second SS is associated with a second CORESET;
- determine that the first set of CCEs is associated with the second set of CCEs;
- receive any of:
- a first PDCCH transmission based on the first beam and the first set of CCEs;
- or
- a second PDCCH transmission based on the second beam and the second set of CCEs;
- and
- decode a downlink control information (DCI) based on any of the first PDCCH transmission or the second PDCCH transmission.
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- determining a first set of control channel elements (CCEs) from a plurality of CCEs, wherein the first set of CCEs is associated with a first beam and a first search space (SS), and wherein the first SS is associated with a first control resource set (CORESET);
- determining a second set of CCEs from the plurality of CCEs, wherein the second set of CCEs is associated with a second beam and a second SS, and wherein the second SS is associated with a second CORESET;
- determining that the first set of CCEs is associated with the second set of CCEs;
- receive any of:
- a first physical downlink control channel (PDCCH) transmission using the first beam and the first set of CCEs;
- or
- a second PDCCH transmission using the second beam and the second set of CCEs;
- and
- decoding a downlink control information (DCI) based on any of the first PDCCH transmission or the second PDCCH transmission.
