Embodiment 1

[0034] In this embodiment, a signal configuration method is provided, 图3. Is a flowchart of a signal configuration method according to an embodiment of the present disclosure, such as 图3. As shown in, the process includes the following steps:

[0035] Step S302: jointly encode the waveform indication information and at least one of the following parameter information: rank indication (RI), precoding indication PMI, reference detection pilot indication SRI, demodulation reference signal (DMRs) configuration, phase tracking reference signal (phase tracking reference signal) configuration, modulation coding scheme (MCS) configuration, power control parameters and resource allocation indication parameters;

[0036] After sending the encoded information in step S304.

[0037] Through the above steps, through the joint coding of waveform indication information and other parameter information, the technical problem of excessive overhead of transmitting waveform indication information in ...

Embodiment 2

[0067] In this embodiment, a signal configuration and indication device is also provided. The device is used to realize the above embodiment and preferred embodiment. It will not be repeated if it has been described. As used below, the term "module" may be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and envisaged.

[0068] 图6. Is a structural block diagram of a signal configuration device according to an embodiment of the present disclosure, such as 图6. As shown, the device comprises:

[0069] An encoding module 60 for jointly encoding the waveform indication information and at least one of the following parameter information: rank indication, precoding indication, reference detection pilot indication, demodulation pilot configuration, phase-to-noise...

Embodiment 3

[0082] This embodiment is an optional embodiment according to the present disclosure, which is used to describe the application in detail in combination with specific embodiments:

[0083] In the joint coding technology of this embodiment, the dynamic switching of waveform indication (WI) mainly uses the following characteristics to reduce the overhead:

[0084] Different sets of optional waveform types can be considered for different codewords. For example, some codewords will destroy the PAPR. Even if dft-s-ofdm is used, the PAPR cannot be controlled, so it will not be combined with it

[0085] The set of optional waveform types supported can be considered for different rank / layer values.

[0086] Different sets of optional waveform types can be considered for different resource regions. Using the same waveform will improve the performance of uplink MU-MIMO (multiple user multiple input multiple output), so you can divide the resource area and set the corresponding waveform ty...

Description

technical field [0001] The present disclosure relates to the field of communication, in particular to a signal configuration, a transmission method and a device. Background technology [0002] In the new radio (NR) of related technologies, uplink transmission supports two transmission waveforms: dft-s-ofdm and cp-ofdm. The former is the uplink SC-FDMA (signal carrier frequency division multiple access) in LTE, and the latter is the downlink waveform of long term evolution (LTE), which is usually referred to as OFDM (orthogonal frequency division multiplexing) or OFDMA (orthogonal frequency division multiple access). Dft-s-ofdm has smaller peak to average ratio and cp-ofdm has better transmission performance. [0003] In NR, uplink supports two transmission modes, one is based on code book (CB) transmission, and the other is not based on codebook. They are called CB based transmission and non CB based transmission respectively. [0004] CB based transmission requires a codebook ag...
