Cross carrier spatial relation indication for semi local sounding reference signal (sp-srs) resources

摘要

Exemplary embodiments include methods for activating or deactivating reference signal (RS) resources usable for management of transmit and/or receive beams for communication with a user equipment (UE) in a wireless communication network. Embodiments include sending, to the UE, one or more control messages comprising configuration of a plurality of RS resources associated with a particular bandwidth part (BWP) of a particular component carrier (CC) in the network. Embodiments also include sending, to the UE, a further control message comprising identification of at least one RS resource, of the plurality, to be activated or deactivated. The further control message can also include, for each identified RS resource, an indication of the identified RS resource's spatial relation with a further resource that is not associated with the particular BWP of the particular CC. Embodiments also include complementary methods performed by a UE, and apparatus configured to perform the exemplary methods.
