Claim of US Patent No. 11,115,996


1. A method in a terminal device for transmission to at least a first network device and a second network device over bundled Transmission Time Intervals (TTIs) comprising:determining that a first TTI for transmission to the first network device overlaps a second TTI for transmission to the second network device based on a first Timing Advance (TA) value associated with the first network device and a second TA value associated with the second network device;
requesting from the first and second network devices a first and a second transmission grants, respectively, based on the first and second TA values, such that an order of the first and second transmission grants requested is based on values of the first and second TA values;
receiving the first and second transmission grants from the first and second network devices, respectively, in the order based on the first and second TA values; and
transmitting data to the first and second network devices in accordance with the order of the first and second transmission grants.
