Abstract
The present disclosure relates to pulse shaping-based reference signals. Signaling indicating information that is associated with pulse shaping and information associated with a target length of a sequence for a reference signal such as a demodulation reference signal (DMRS) is communicated between a first communication device and a second communication device in a wireless communication network. The reference signal is also communicated in the wireless communication network. The reference signal comprises a sequence of the target length to which the pulse shaping has been applied. The sequence comprises a base sequence that is determined based on the pulse shaping.
Claims20
A method comprising:
- communicating signaling between a first communication device and a second communication device in a wireless communication network, the signaling indicating information associated with pulse shaping and information associated with a demodulation reference signal (DMRS) sequence, and wherein the information associated with pulse shaping comprises any one or more of:
- a pulse shape type, a roll off factor α, a bandwidth expansion, a bandwidth expansion factor β, a base sequence length parameter that is based on the pulse shaping, or a length of a base sequence of the DMRS sequence;
- and
- communicating a DMRS in the wireless communication network, the DMRS comprising a DMRS sequence to which the pulse shaping has been applied.
An apparatus comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium, coupled to the at least one processor, storing programming for execution by the at least one processor, the programming including instructions to:
- communicate signaling between a first communication device and a second communication device in a wireless communication network, the signaling indicating information associated with pulse shaping and information associated with a demodulation reference signal (DMRS) sequence, and wherein the information associated with pulse shaping comprises any one or more of:
- a pulse shape type, a roll off factor α, a bandwidth expansion, a bandwidth expansion factor β, a base sequence length parameter that is based on the pulse shaping, or a length of a base sequence of the DMRS sequence;
- and
- communicate a DMRS in the wireless communication network, the DMRS comprising a DMRS sequence to which the pulse shaping has been applied.
A non-transitory computer readable medium storing programming that is executable by at least one processor, the programming including instructions to:
- communicate signaling between a first communication device and a second communication device in a wireless communication network, the signaling indicating information associated with pulse shaping;
- and
- communicate a demodulation reference signal (DMRS) in the wireless communication network based on the information associated with pulse shaping, wherein a length N of a base sequence of the DMRS is a prime number that is closest to q*M, a largest prime number such that N≤q*M, or a smallest prime number such that N≥q*M, and wherein q* is a base sequence length parameter that is based on the information associated with pulse shaping, and M is a target length of a DMRS sequence.
