Common and Default Beam Indication of Uplink and Downlink Channel Resources and/or Reference Signals

A method performed by a User Equipment (UE), the method comprising:

• receiving, from a network node, a single explicit indication for at least one bandwidth part of at least one component carrier (CC) via a medium access control-control element (MAC-CE) message, or via a downlink control information (DCI) message, wherein the indication provides:
• one or more receive setting(s) for at least two downlink (DL) channels, or one DL channel and one DL resource, or two DL resources, or
• one or more transmit setting(s) for at least two uplink (UL) channels, or one UL channel and one UL resource, or two UL resources, or
• one or more transmit setting(s) for at least one UL channel and/or resource and one or more receive setting(s) for at least one DL channel and/or resource;
• wherein the setting(s) for said UL and/or DL channel(s) and/or resource(s) are received, from the network node, via one or more transmission configuration indication TCI) configuration(s) in the received single explicit indication, wherein a TCI configuration provides at least one reference RS or at least one reference resource along with an indication of transmission and/or reception parameter(s) to be derived or obtained from each one of the RS(s) or the reference resources(s) provided by the TCI configuration(s);
• and
• applying said setting(s) provided in the single explicit indication for the reception of said DL channel(s) and/or resource(s), and/or for the transmission of said UL channel(s) and/or resource(s).

A user equipment UE comprising a processor and a memory containing instructions executable by the processor, whereby said UE is operative to:

• receive, from a network node, a single explicit indication for at least one bandwidth part of at least one component carrier (CC) via a medium access control-control element (MAC-CE) message, or via a downlink control information (DCI) message, wherein the indication provides:
• one or more receive setting(s) for at least two downlink (DL) channels, or one DL channel and one DL resource, or two DL resources, or
• one or more transmit setting(s) for at least two uplink (UL) channels, or one UL channel and one UL resource, or two UL resources, or
• one or more transmit setting(s) for at least one UL channel and/or resource and one or more receive setting(s) for at least one DL channel and/or resource,
• wherein the setting(s) for said UL and/or DL channel(s) and/or resource(s) are received, from the network node, via one or more transmission configuration indication TCI) configuration(s) in the received single explicit indication, wherein a TCI configuration provides at least one reference RS or at least one reference resource along with an indication of transmission and/or reception parameter(s) to be derived or obtained from each one of the RS(s) or the reference resources(s) provided by the TCI configuration(s);
• and
• apply said setting(s) provided in the single explicit indication for the reception of said DL channel(s) and/or resource(s), and/or for the transmission of said UL channel(s) and/or resource(s).

A method performed by a network node, the method comprising:

• transmitting, to the UE, a single explicit indication for at least one bandwidth part of at least one carrier component (CC) via a medium access control-control element (MAC-CE) message or via a DCI message wherein the indication provides:
• one or more receive setting(s) for at least two Downlink (DL) channels, or one DL channel and one DL resource, or two DL resources, or
• one or more transmit setting(s) for at least two Uplink (UL) channels, or one UL channel and one UL resource, or two UL resources, or
• one or more transmit setting(s) for at least one UL channel and/or resource and one or more receive setting(s) for at least one DL channel and/or resource;
• wherein the setting(s) for said UL and/or DL channel(s) and/or resource(s) are transmitted, from the network node, to the UE via one or more transmission configuration indication TCI configuration(s), wherein a TCI configuration provides at least one reference RS or at least one reference resource along with an indication of transmission and/or reception parameter(s) to be derived or obtained from each one of the RS(s) or the reference resources(s) provided by the TCI configuration(s), for enabling the UE to apply said settings provided in the single explicit indication for the reception of said one or more DL channel(s) or resource(s) and/or for the transmission of said one or more UL channel(s) and/or resource(s);
• and
• receiving, from the UE, the at least one UL channel and/or the at least one UL resource.

A network node comprising a processor and a memory containing instructions executable by the processor, whereby said network node is operative to:

• transmit, to the UE, a single explicit indication for at least one bandwidth part of at least one carrier component (CC) via a medium access control-control element (MAC-CE) message or via a DCI message wherein the indication provides:
• one or more receive setting(s) for at least two Downlink (DL) channels, or one DL channel and one DL resource, or two DL resources, or
• one or more transmit setting(s) for at least two Uplink (UL) channels, or one UL channel and one UL resource, or two UL resources, or
• one or more transmit setting(s) for at least one UL channel and/or resource and one or more receive setting(s) for at least one DL channel and/or resource;
• wherein the setting(s) for said UL and/or DL channel(s) and/or resource(s) are transmitted, from the network node, to the UE via one or more transmission configuration indication TCI configuration(s), wherein a TCI configuration provides at least one reference RS or at least one reference resource along with an indication of transmission and/or reception parameter(s) to be derived or obtained from each one of the RS(s) or the reference resources(s) provided by the TCI configuration(s), for enabling the UE to apply said settings provided in the single explicit indication for the reception of said one or more DL channel(s) or resource(s) and/or for the transmission of said one or more UL channel(s) and/or resource(s);
• and
• receive, from the UE, the at least one UL channel and/or the at least one UL resource.
