Abstract
Systems and methods of PUCCH reliability are provided. In some embodiments, a method performed by a wireless device includes: receiving an activation command to activate a first and a second spatial relation; optionally determining the first and the second spatial relation based on one or more Downlink TCI states; transmitting the UCI according to the first spatial relation in a first set of symbols or slots; and transmitting the UCI according to the second spatial relation in a second set of symbols or slots. In this way, fewer changes to the specifications are required. The existing RRC configuration for spatial relations and MAC CE activation might be used. Spatial relations might be selected by the MAC CE. Also, the existing DCI can be used where a PUCCH resource is selected by PRI bits. Since MAC CE is used to select spatial relations, different combinations can be selected dynamically.
