Title:
PRIORITIZATION FOR UPLINK TRANSMISSIONS IN CASE OF HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK REPETITION
Document Type and Number:
WIPO Patent Application WO/2013/168137
Kind Code:
A3
Abstract:
Communication systems, such as long term evolution, can benefit from enhancements to hybrid automatic repeat request (HARQ) handling. For example, certain LTE systems can benefit from prioritization of uplink (UL) transmissions in case of HARQ feedback repetition, A method can include, when a random access channel preamble collides with ACK/NACK, prioritizing the preamble over ACK/NACK, The method can be performed regardless of repetition being configured or not. Another method can include, when a dedicated scheduling request or a msg3 collides with an ACK/NACK repetition, conditionally prioritizing the dedicated scheduling request or the msg3 transmission.
