Problems solved by technology

[0008] In current networks, UL / DL configurations are semi-statically configured and thus do not match instantaneous traffic scenarios
This results in inefficient resource utilization in both UL and DL, especially in cells with few users

Abstract

The present disclosure relates to a method for HARQ ACK / NACK bundling on a PUSCH in a TDD system. The method comprises choosing a scramble code selecting parameter from a predefined set of scramble code selecting parameters, wherein each scramble code selecting parameter is associated with one of one or more downlink subframes to be received and one or more HARQ ACK / NACK bits with respect to the one or more downlink subframes are to be transmitted in a predetermined uplink subframe, or calculating a scramble code selecting parameter based on the number of detected downlink subframes. The method also comprises scrambling one or more HARQ ACK / NACK bits using the chosen scramble code selecting parameter or the calculated scramble code selecting parameter for bundling on the PUSCH. The present disclosure also relates to corresponding UE and a radio network node for HARQ ACK / NACK bundling on a PUSCH in a TDD system.

Description

technical field [0001] The techniques presented in this disclosure relate generally to wireless communication networks, and in particular, but not exclusively, to radio communication networks employing time division duplexing (TDD), such as Long Term Evolution (LTE) TDD. More specifically, the present disclosure relates to a method, user equipment and radio network for Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) / Negative Acknowledgment (NACK) bundling on a Physical Uplink Shared Channel (PUSCH) in a dynamic TDD system node. Background technique [0002] This section is intended to provide background for a number of different embodiments of the techniques described in this disclosure. The descriptions in this section may include concepts that could be implemented, but not necessarily concepts that have been previously conceived or implemented. Therefore, unless otherwise indicated herein, what is described in this section does not constitute prior art to the...
