Radio Access Technology with Non-Continuous and Periodic PUSCH Transmission

摘要

In some embodiments, a user equipment (UE) and base station implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. Embodiments are also presented which enable a UE that is peak current limited to utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge/negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.
