A single reference signal sequence is used both for demodulation and detection of a data channel, and for channel sounding, such that a reference signal sequence part used for the demodulation and detection of the data channel is in a power offset compared to a reference signal sequence part used for the channel sounding. Code division multiplexing is applied on a reference signal sequence by using a cyclic shift of a whole length of the sequence. The cyclic shift is selected such that reference signal sequences allocated to the different user terminals are orthogonal over a minimum allocation granularity of the data channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting a reference signal in a communication system","description":"A method for reference signal transmission is disclosed, wherein a demodulation reference signal DMRS and a sounding reference signal SRS is transmitted in a same time domain resource from a user term","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9706533","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
