Uplink beam indication with activated beams

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive configuration parameters of a plurality of uplink (UL) transmission configuration indicator (TCI) codepoints, wherein the plurality of UL TCI codepoints comprise:
• a first codepoint indicating that an activated downlink (DL) TCI state is applicable for an UL signal transmission;
• and
• a second codepoint indicating that a sounding reference signal resource indicator (SRI) is applicable for the UL signal transmission;
• receive a control command indicating:
• a codepoint for an UL signal;
• and
• a panel associated with the wireless device, wherein the panel is determined based on at least one of wireless channel condition or beam blockage condition;
• determine a spatial domain filter based on the indicated codepoint being one of the plurality of UL TCI codepoints, wherein the spatial domain filter is determined using:
• the activated DL TCI state in response to the indicated codepoint being the first codepoint;
• and
• the SRI in response to the indicated codepoint being the second codepoint;
• and
• transmit the UL signal using the determined spatial domain filter via the panel indicated by the control command.

A system comprising:

• a base station;
• and
• a wireless device comprising:
• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive, from the base station, configuration parameters of a plurality of uplink (UL) transmission configuration indicator (TCI) codepoints, wherein the plurality of UL TCI codepoints comprise:
• a first codepoint indicating that an activated downlink (DL) TCI state is applicable for an UL signal transmission;
• and
• a second codepoint indicating that a sounding reference signal resource indicator (SRI) is applicable for the UL signal transmission;
• receive, from the base station, a control command indicating:

• and
• a panel associated with the wireless device, wherein the panel is determined by the base station based on at least one of wireless channel condition or beam blockage condition;
• determine a spatial domain filter based on the indicated codepoint being one of the plurality of UL TCI codepoints, wherein the spatial domain filter is determined using:
• the activated DL TCI state based on the indicated codepoint being the first codepoint;
• and
• the SRI based on the indicated codepoint being the second codepoint;
• and
• transmit, to the base station, the UL signal using the determined spatial domain filter via the panel indicated by the control command.
