A pending scheduling request may be refrained from being transmitted due to the collision. The SR counter may be refrained from incrementing and the SR prohibit timer may be refrained from starting such that additional latency is not introduced into the scheduling request procedure. Alternatively, a pending scheduling request may be transmitted with the ACK/NACK repetition signal in the same subframe when the collision occurs. The ACK/NACK repetition signal may be transmitted on the SR PUCCH resource to indicate a positive scheduling request. If there is no pending scheduling request to be transmitted, the ACK/NACK repetition signal may be transmitted on the ACK/NACK PUCCH resource."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handling scheduling request collisions with an ACK/NACK repetition signal","description":"Systems and methods for handling of scheduling request collisions with an ACK/NACK repetition signal are provided.
