Efficient Spatial Relation Indication for Physical Uplink Control Channel (PUCCH) Resources

Abstract

Exemplary embodiments include methods for a network node to receive PUCCH transmissions by a user equipment (UE). Such methods include sending, to the UE, a control message including: identification of a first spatial relation of a plurality of spatial relations, configured for the UE, that are associated with one or more reference signals (RS) transmitted by the network node or by the UE; and an indication of to which of the following the first spatial relation applies: a single PUCCH resource, or at least one group of PUCCH resources configured for the UE. Such methods include receiving, from the UE, a PUCCH message transmitted according to the first spatial relation using a PUCCH resource, configured for the UE, to which the first spatial relation applies. Embodiments also include complementary methods for a UE, as well as network nodes and UEs configured to perform such methods.
