Background

In the research requirements of R18, uplink coverage is always one of the bottlenecks of system performance, which affects signal quality and user experience, including operators, with strong uplink coverage enhancement requirements.

Referring to fig. 1, the wireless communication system includes a network device and a terminal. The terminal is connected with the network equipment through wireless resources and performs data transmission.

It is further understood that the wireless communication system of the disclosed embodiments is a network that provides wireless communication functionality. The wireless communication system may employ different communication techniques such as code division Multiple access (code division Multiple access, CDMA), wideband code division Multiple access (wideband code division Multiple access, WCDMA), time division Multiple access (time division Multiple access, TDMA), frequency division Multiple access (frequency division Multiple access, FDMA), orthogonal frequency division Multiple access (orthogonal frequency-division Multiple access, OFDMA), single carrier frequency division Multiple access (SINGLE CARRIER FDMA, SC-FDMA), carrier sense Multiple access/collision avoidance (CARRIER SENSE Multiple ACCESS WITH Collision Avoidance). Networks may be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, according to factors such as capacity, rate, delay, etc., and the 5G networks may also be referred to as New Radio (NR). For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (bs), a home base station, an Access Point (AP) in a WIFI (WIRELESS FIDELITY) system, a wireless relay node, a wireless backhaul node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., or may be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited. In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). In addition, in the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device.

Currently, some examples of terminals are: a smart Phone (Mobile Phone), a customer premises equipment, a pocket computer (Pocket Personal Computer, PPC), a palm computer, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, in the case of a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure are not limited to the specific technology and specific device configuration adopted by the terminal.

In the related art, when a terminal and a network device perform data transmission, if the data volume of each data transmission is smaller, an unlicensed uplink scheduling is introduced to reduce signaling overhead in a random access process and an uplink scheduling permission process.

Unlicensed Physical Uplink SHARED CHANNEL (PUSCH) transmission supports two scheduling-free schemes in uplink, and the difference is that the activation modes are different:

Configuration authorization Type 1 (Type 1): providing uplink grants by radio resource control (Radio Resource Control, RRC) signaling, including activation of grants; the RRC configuration takes effect immediately upon correct reception. All transmission parameters including period, time offset and frequency resource, and modulation coding mode used for uplink transmission are configured through RRC signaling. Upon receiving the RRC configuration, the terminal starts transmitting with the grant of the configuration at the moment given by the period and the offset. The offset is to control at which time the terminal is allowed to transmit.

Configuration authorization Type 2 (Type 2) is that the RRC provides a transmission period, and the base station realizes resource activation and configuration of partial transmission parameters through downlink control information DCI, so that activation transmission of the authorization configuration is realized; after receiving the activation command, the terminal transmits according to a preset period if data is sent in the buffer memory, and does not transmit any data if no data exists. The activation time is clarified at the transmission time of the downlink control channel (physical downlink control channel, PDCCH). The terminal acknowledges the activation/deactivation configuration grant type 2 by sending MAC control signaling upstream.

In the research requirements of R18, uplink coverage is always one of the bottlenecks of system performance, which affects signal quality and user experience, including operators, with strong uplink coverage enhancement requirements. Currently, in NR, two uplink waveforms are supported: cyclic prefix orthogonal frequency division multiplexing (Cyclic Prefix Orthogonal Frequency-Division Multiplexing, CP-OFDM) waveforms and discrete fourier transformed orthogonal frequency division multiplexing (Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing, DFTS-OFDM) waveforms.

Compared with the CP-OFDM waveform, the peak-to-average power ratio of the DFTS-OFDM waveform is about 3dB lower than that of the CP-OFDM waveform, and the DFTS-OFDM waveform is more suitable for the scene with limited uplink coverage due to the lower peak-to-average power ratio. For example, cell edge users are also in Frequency Range 2 (Frequency Range 2, fr 2), and the problem of uplink coverage of the CP-OFDM waveform is more pronounced.

In the related art, a CP-OFDM waveform or a DFTS-OFDM waveform used in uplink transmission of a terminal is semi-statically configured through radio resource control (Radio Resource Control, RRC) signaling. By configuring a waveform of the terminal for uplink transmission in "transformPrecoder" in a Physical Uplink SHARED CHANNEL (PUSCH) configuration parameter, if "transformPrecoder" is configured as "enable", the waveform of the terminal for uplink transmission is a DFTS-OFDM waveform, and if "transformPrecoder" is configured as "disable", the waveform of the terminal for uplink transmission is a CP-OFDM waveform.

Therefore, when switching between the CP-OFDM waveform and the DFTS-OFDM waveform is performed, RRC reconfiguration is required, and communication performance is low.

Based on this, the embodiment of the disclosure provides a configuration method for uplink waveforms, which determines waveform switching configuration information through a terminal and reports the waveform switching configuration information to network equipment, and can realize dynamic switching of uplink waveforms through reporting of the terminal.

In step S12, waveform switching configuration information is transmitted to the network device.
