A Downlink Control Information (DCI) message can be received in a first subframe. The DCI message can indicate a resource assignment and a modulation and coding scheme and can indicate a plurality of cyclic shifts from which a User Equipment (UE) may select one cyclic shift for transmission in a second subframe for an uplink carrier. A cyclic shift can be selected from the plurality of indicated cyclic shifts based on a selection criterion. A data packet can be transmitted on a Physical Uplink Shared Channel (PUSCH) in a resource indicated by the resource assignment and modulation and coding scheme using a Demodulation Reference Signal (DMRS) based on the selected cyclic shift in the second subframe on the uplink carrier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reducing latency of LTE uplink transmissions","description":"A method and apparatus reduce latency of Long Term Evolution (LTE) uplink transmissions.
