Abstract: A base station performs joint channel estimation for a set of physical uplink control channels (PUCCHs), where one or more PUCCHs of the set of PUCCHs comprises a corresponding DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUCCHs, one or more PUCCHs of the set of PUCCHs comprising a DMRS from the base station. The base station transmits, and the UE receives, spatial filter or power control information elements for each PUCCH of the set of PUCCHs. The UE transmits the PUCCHs comprising corresponding DMRS based on a same spatial filter with a same power control parameters, spatial filter or power control information element for a first PUCCH of the set of PUCCHs indicating the same spatial filter or same power control parameter, the set of PUCCHs having phase continuity.

Abstract: Aspects for enabling Multiple-Input-Multiple-Output (MIMO) communications using a plurality of transmitters across at least two supported frequency bands are disclosed. The apparatus may be a user equipment (UE) that includes, for each UE-supported frequency band, a plurality of transmitters capable when configured of coherently transmitting the received information over the frequency band with information to be transmitted to a base station. The apparatus can identify MIMO coherence capability information for the supported frequency bands on a per-band and a per-band combination basis. The apparatus may determine a proposed transmission configuration based on the MIMO capability information and may report, to the base station, the proposed transmission configuration.
