Title:

物理アップリンク制御チャネル（ＰＵＣＣＨ）リソースのための効率的な空間関係指示

Document Type and Number:

Japanese Patent JP7182640

Kind Code:

B2

Abstract:

Exemplary embodiments include methods performed by a network node to configure PUCCH resources usable in communication with UE in a wireless network. Embodiments include sending, to the UE, one or more control messages comprising: configuration of a plurality of PUCCH resources; and identification of a plurality of spatial relations associated with one or more reference signals transmitted by the UE or the network node. Embodiments also include sending, to the UE, a further control message comprising: identification of a first spatial relation of the plurality of spatial relations; and indication of whether the first spatial relation applies to a single PUCCH resource of the configured PUCCH resources, or to at least one group of PUCCH resources of the configured PUCCH resources. Exemplary embodiments also include complementary methods performed by a UE, as well as network nodes and UEs configured to perform the exemplary methods.
