Description

Transmission waveform parameter determining method, device and storage medium

Technical Field

The disclosure relates to the technical field of communication, and in particular relates to a transmission waveform parameter determining method, a transmission waveform parameter determining device and a storage medium.

Background

In the design physical layer of the new generation communication technology, waveforms are a core technology component. The third generation partnership project (3rd Generation Partnership Project,3GPP) selects the spread use of frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) while adding cyclic prefix frequency division multiplexing (CP-OFDM) and discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveforms to the new generation communication technology in the uplink and downlink, which can be the transmission waveforms used by the terminal to transmit message 3 (msg.3) during random access.

In the related art, transmission waveform parameters corresponding to transmission waveforms used by a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) of msg.3 are configured by a remaining system minimum message (Remaining minimum system information, RMSI). The object for CP-OPDM and DFT-S-OFDM may be a terminal with relatively good coverage, or a terminal requiring coverage enhancement or a capability reduction terminal (Reduced capability, redcap). However, all terminals use the same waveform configuration parameters, i.e., all terminals use waveform configuration parameters corresponding to CP-OPDM or DFT-S-OFDM, resulting in affecting transmission efficiency or peak-to-average power ratio (Peak to Average Power Ratio, PAPR) of a portion of the terminals.

The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Fig. 1 is a diagram illustrating a communication system architecture of a network device and a terminal according to an exemplary embodiment. The transmission waveform parameter determining method provided by the present disclosure may be applied to the communication system architecture diagram shown in fig. 1. As shown in fig. 1, the network side device may send signaling based on the architecture shown in fig. 1.

It should be understood that the communication system between the network device and the terminal shown in fig. 1 is only schematically illustrated, and the wireless communication system may further include other network devices, for example, a core network device, a wireless relay device, a wireless backhaul device, etc., which are not shown in fig. 1. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

It is further understood that the wireless communication system of the embodiments of the present disclosure 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 (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 wireless fidelity (wireless fidelity, WIFI) 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., may also 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. In the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device. 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.

Further, a Terminal referred to in the present disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and may be a device that provides voice and/or data connectivity to a User, for example, a handheld device, an in-vehicle device, or the like that has a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a palm top 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 a communication system, aiming at the scenes of low-speed high-delay and the like (such as meter reading, environment monitoring and the like) in the service of the internet of things, two large technologies of MTC and NB-IoT are proposed by related technologies. Current NB-IoT technologies can support rates of several hundred K at maximum and MTC can support rates of several M at maximum. However, with the continuous development of internet of things services (such as monitoring, smart home, wearable devices, industrial sensor detection, etc.), generally, a rate of several tens to one hundred M is required, and the requirement for time delay is also relatively increased. Therefore, in the communication system, the two technologies of MTC and NB-IoT cannot meet the current requirements of the internet of things service. Therefore, a new user equipment is designed in a new air interface of the communication system to cover the service requirement of the middle-end internet of things equipment requiring tens to one hundred M, and meanwhile, the service requirement of the middle-end internet of things equipment with higher time delay is provided. Currently, in the third generation partnership project (3rd Generation Partnership Project,3GPP) standardization, a user equipment for covering a service requirement of a middle-end internet of things device requiring a rate of several tens to one hundred megameters and having a higher time delay is called a capability reduction (Reduced capability) terminal, abbreviated as a Redcap terminal or NR-lite.

Meanwhile, in another aspect, the Redcap terminal is generally required to meet requirements of low cost, low complexity, a certain degree of coverage enhancement, power saving, and the like. However, the new air interface communication technology is designed for high-end terminals with high speed, low time delay and the like, and cannot meet the requirements of NR-lite. There is therefore a need to retrofit current new air interface communication technologies to meet the above requirements of NR-lite. For example, the Radio Frequency (RF) bandwidth of the new air interface internet of things (e.g., to 5MHz or 10MHz; or the buffer size of NR-lite) may be limited according to the requirements of low cost and low complexity, thereby limiting the size of the transport block received each time, and so on. For another example, according to the requirement of power saving, the communication flow may be simplified to reduce the number of times the Redcap terminal detects the downlink control channel, and so on.

In the development process of the new generation communication technology, waveforms are a core technology component in the design physical layer of the new generation communication technology. The 3GPP chooses to extend the use of frequency division multiplexing technology OFDM while adding CP-OFDM and DFT-s-OFDM for new generation communication technologies in both uplink and downlink, with the CP-OPDM waveforms being primarily used to obtain higher throughput, e.g., for cell-center users. DFT-s-OFDM is mainly used in power limited scenarios to achieve lower PARP. The CP-OPDM and DFT-s-OFDM may be transmission waveforms used by the terminal for transmitting msg.3 in a random access procedure.

In the related art, transmission waveform parameters corresponding to a transmission waveform used by PUSCH of msg.3 are configured by RMSI, which is a common message. The same transmission waveform is used by msg.3 for all terminals in the cell. In the following embodiment, whether the msg.3 of the terminal uses DFT-s-OFDM or not needs to be activated by RMSI.

In the new generation communication technology, a coverage enhancement function is introduced, and a terminal can perform enhancement of uplink coverage through full power repetition (repetition). In addition, as described above, the Redcap terminal is also introduced, and loss (loss) of 3db wire efficiency (antenna efficiency) occurs due to the limitation of the form of the Redcap terminal. In this case, even when the sub coverage is poor, it is necessary to perform full power transmission or full power repetition transmission. In the related art, the object aimed by the CP-OPDM and the DFT-s-OFDM can be a terminal with relatively good coverage, and also can be a terminal needing coverage enhancement or a Redcap terminal. Since the commonly configured transmission waveform parameters in RMSI will no longer match the channel loading of the terminal. Therefore, when configuring the common transmission waveform parameters in RMSI, one embodiment is to configure the transmission waveform parameters corresponding to DFT-s-OFDM in RMSI, and all terminals transmit msg.3 using DFT-s-OFDM. This embodiment is relatively conservative, in that the transmission efficiency (SE) of terminals with better channel conditions will be lost. In one embodiment, transmission waveform parameters corresponding to CP-OPDM are configured in RMSI, and all terminals transmit msg.3 using CP-OPDM. This embodiment is relatively aggressive in that the terminal PAPR that needs coverage enhancement is high.

Based on this, the present disclosure provides a transmission waveform parameter determination method. Different transmission waveform parameters are configured for different coverage enhancement terminals, and different types of terminals can transmit msg.3 based on different transmission waveforms. Namely, the transmission waveform parameters corresponding to the CP-OPDM are configured for the normally covered terminal, and the transmission waveform parameters corresponding to the DFT-s-OFDM are configured for the terminal needing coverage enhancement. The method can ensure the PAPR required by the terminal with poor coverage and can also ensure the transmission efficiency of the terminal with good coverage.

Fig. 2 is a flowchart illustrating a transmission waveform parameter determination method according to an exemplary embodiment. This embodiment may be implemented independently or in combination with any one or more embodiments of the present disclosure. As shown in fig. 2, the transmission waveform parameter determining method is used in a terminal and includes the following steps.

In step S11, first indication information is received.

In an embodiment of the present disclosure, the first indication information is used to indicate a transmission waveform parameter. The transmission waveform parameters at least comprise a first transmission waveform parameter and a second transmission waveform parameter. Illustratively, the transmission waveform parameters are at least transmission waveform parameters corresponding to CP-OPDM and transmission waveform parameters corresponding to DFT-s-OFDM.

In step S12, transmission waveform parameters for use in transmitting a message are determined according to at least one of the state of the terminal and the indication information.

In the embodiment of the disclosure, the states of the terminals at least include a first state and a second state, and the first state terminal and the second state terminal have different performance parameters and/or channel states. The first state terminal indicates that the state of the terminal is a first state, and the second state terminal indicates that the state of the terminal is a second state. For example, the first state is a normal capability state, and the first state terminal is a terminal having normal capability. The second state is a low capability state and the second state terminals are terminals having a low capability state. This is of course merely an illustration and is not a specific limitation on the first and second states of the present disclosure.

According to the transmission waveform parameter determining method provided by the embodiment of the disclosure, different transmission waveform configuration parameters are configured for the terminals in different states, so that the PAPR required by the terminals with poor coverage can be ensured when the terminals send messages, and the transmission efficiency of the terminals with good coverage can be ensured.

In some embodiments of the present disclosure, the state of the terminal may be a reference signal measurement, in other words, the first state terminal and the second state terminal have different reference signal measurements. The reference signal measurement may be a reference signal received power (Reference Signal Receiving Power, RSRP).

In some embodiments of the present disclosure, the performance parameter of the terminal may be one of:

different types of terminals;

terminals of different versions; and

terminals with different functions.

For example, the first state terminal and the second state terminal may be different types of terminals; alternatively, the first state terminal and the second state terminal may be different versions of terminals; alternatively, the first state terminal and the second state terminal may be terminals of different functions.

Fig. 3 is a flowchart illustrating a transmission waveform parameter determination method according to an exemplary embodiment. This embodiment may be implemented independently or in combination with any one or more embodiments of the present disclosure. As shown in fig. 3, the transmission waveform parameter determining method is used in a terminal and includes the following steps.

In step S21, second instruction information is received.

In the embodiment of the disclosure, the second indication information is used for indicating the terminal to determine the state of the terminal. The terminal performs channel state measurement based on the second indication message sent by the network side, determines a reference signal measurement value, and further determines the state of the terminal itself based on the reference signal measurement value.

In some embodiments of the present disclosure, the second indication message may be an indication message different from the first indication message, that is, a message used by the network side device to indicate the transmission waveform parameter is different from a message used to indicate the terminal to determine the state of the terminal.

In some embodiments of the present disclosure, the second indication message may also be the same indication information as the first indication message, that is, the message used by the network side device to indicate the transmission waveform parameter and the message used to indicate the terminal to determine the state of the terminal are in the same indication message.

In the embodiment of the present disclosure, the correspondence between the transmission waveform parameters, the physical random access channel (Physical Random Access Channel, PRACH) set, and the state of the terminal may be the following correspondence:

the first transmission waveform parameter corresponds to a first PRACH set, the first PRACH set corresponding to a first state terminal. The second transmission waveform parameters correspond to a second PRACH set, the second PRACH set corresponding to a second state terminal.

Wherein, in some embodiments of the present disclosure, the parameters of the first PRACH set and the second PRACH set are not identical or identical.

In some embodiments of the present disclosure, the first indication message includes: indication information for indicating waveform parameters of the first state terminal application, indication information for indicating waveform parameters of the second state terminal application. The terminal may receive a first indication message based on the RSMI. As described above, the first transmission waveform parameter corresponds to the first PRACH set, the first PRACH set corresponds to the first state terminal, the second transmission waveform parameter corresponds to the second PRACH set, the second PRACH set corresponds to the correspondence between the second state terminals, the terminal determines, according to its own state, to report msg.1 in the corresponding PRACH set, and the network determines, according to the received msg.1, the transmission waveform parameter used by the terminal for subsequent message transmission. Wherein the subsequent transmission message may be transmission msg.3.

For example, referring to table 1, the terminal determines its own state according to the range of RSRP, the terminal sends msg.1 on the corresponding PRACH resource according to its own state, and the network side device may determine, based on the received msg.1, a transmission waveform used by the terminal to subsequently send msg.3.

Wherein the value of each element is independent of any other element value in table 1. It will be appreciated by those skilled in the art that the values of each of the elements in Table 1 are a separate embodiment.

In some embodiments of the present disclosure, the first indication message may further include transmission waveform parameter indication information used by a terminal in one of the states of the plurality of terminals. In other words, the terminal may receive the first indication message based on the RMSI message, determine a transmission waveform parameter applied by the terminal in one state based on the indication information included in the first indication message, and the terminal in the other state uses the predefined transmission waveform parameter. The indication information of the first indication message for indicating the transmission waveform parameter applied by the terminal may be specific to the terminal in the first state or specific to the terminal in the second state.

In some possible embodiments, in response to the terminal being a first state terminal, it is determined that the first state terminal uses predefined transmission waveform parameters. The predefined transmission waveform parameters may be default transmission waveform parameters set in the terminal or determined by the communication protocol.
