Description

Transmission waveform parameter determination method, device and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for determining transmission waveform parameters, 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 (3 GPP) option extension uses Frequency Division Multiplexing (OFDM) while adding a cyclic prefix Frequency Division Multiplexing waveform (CP-OFDM) and a discrete fourier transform spread Orthogonal Frequency Division Multiplexing waveform (DFT-S-OFDM) to the new Generation communication technology in uplink and downlink, which may be transmission waveforms used by the terminal to send message 3(msg.3) in a random access procedure.

In the related art, transmission waveform parameters corresponding to a transmission waveform used by a Physical Uplink Shared Channel (PUSCH) of msg.3 are configured by a Remaining system minimum information (RMSI). The CP-OPDM and DFT-S-OFDM target may be a terminal with relatively good coverage, or may be a terminal requiring coverage enhancement or a Reduced capability terminal (Redcap). However, all terminals use the same waveform configuration parameter, i.e., all terminals use the waveform configuration parameter corresponding to CP-OPDM or DFT-S-OFDM, resulting in affecting the transmission efficiency or Peak to Average Power Ratio (PAPR) of some terminals.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a diagram illustrating a communication system architecture for a network device and a terminal, according to an example embodiment. The transmission waveform parameter determination method provided by the present disclosure can 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 is understood that the communication system of the network device and the terminal shown in fig. 1 is only a schematic illustration, 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, and the like, which are not shown in fig. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the embodiments of the present disclosure is a network providing wireless communication functions. Wireless communication systems may employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single Carrier FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance (Carrier Sense Multiple Access). Networks can 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 and delay of different networks, and the 5G networks can also be referred to as New Radio Networks (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network 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 (enb), a home base station, an Access Point (AP), a wireless relay node, a wireless backhaul node, a Transmission Point (TP), a Transmission and Reception Point (TRP) in a wireless fidelity (WIFI) system, and the like, and may also be a gNB in an NR system, or may also be a component or a part of a device constituting the base station. When a vehicle networking (V2X) communication system, the network device may also be a vehicle-mounted device. It should be understood that, in the embodiments of the present disclosure, the specific technology and the specific device form adopted by the network device are not limited.

Further, the Terminal referred to in this disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, and is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device having a wireless connection function, a vehicle-mounted device, and the like. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc. Furthermore, when being a communication system of the internet of vehicles (V2X), the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and the specific device forms adopted by the terminal.

In a communication system, two major technologies of MTC and NB-IoT are provided aiming at scenes such as low-rate and high-delay (such as meter reading and environment monitoring) in the service of the Internet of things in the related technology. Currently NB-IoT technologies can support a rate of several hundred K at maximum, and MTC can support a rate of several M at maximum. However, with the continuous development of internet of things services (e.g., monitoring, smart home, wearable device, and industrial sensor detection services), a rate of several tens to one hundred meters is generally required, and the requirement for time delay is relatively increased. Therefore, in a communication system, the MTC and NB-IoT technologies cannot meet the requirements of the current internet of things service. Therefore, a new user equipment is designed in a new air interface of a communication system to cover the service requirement of the middle-end internet of things equipment which requires a speed of dozens to one hundred meters and has higher time delay. In the current 3rd Generation Partnership Project (3 GPP) standardization, a ue for covering service requirements of a middle-end internet of things device requiring several tens to one hundred megabits of speed and having a higher delay is called a Reduced capability (Reduced capability) terminal, called a Redcap terminal or NR-lite for short.

Meanwhile, in another aspect, a Redcap terminal generally needs to meet requirements of low cost, low complexity, coverage enhancement to a certain extent, 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 above requirements of NR-lite. Therefore, the current new air interface communication technology needs to be modified to meet the above requirements of NR-lite. For example, the Radio Frequency (RF) bandwidth of the new air interface internet of things may be limited (e.g., to 5MHz or 10 MHz; or the size of the buffer of NR-lite is limited), so as to limit the size of the transmission block received each time, and so on, according to the requirements of low cost and low complexity. For another example, according to the requirement of power saving, the communication flow can be simplified, so as to reduce the number of times that the Redcap terminal detects the downlink control channel, and the like.

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

In the related art, the transmission waveform parameters corresponding to the transmission waveform used by the PUSCH of msg.3 are configured by the RMSI, which is a common message. Msg.3 for all terminals in the cell use the same transmit waveform. Whether msg.3 of the terminal uses DFT-s-OFDM needs to be activated by RMSI as follows.

In a new generation of communication technology, a coverage enhancement function is introduced, and a terminal can perform uplink coverage enhancement through full power repetition (repetition). Also, as a Redcap termination is also introduced as described above, a loss (loss) of 3db wire efficiency (antenna efficiency) occurs due to the limitation of the Redcap termination morphology. In this case, when the sub-coverage is poor, full power transmission or repeated full power transmission is also required. In the related art, the objects aimed by the CP-OPDM and DFT-s-OFDM may be terminals with relatively good coverage, or terminals requiring coverage enhancement or Redcap terminals. Since the commonly configured transmission waveform parameters in the RMSI will no longer match the channel loading of the terminal. Therefore, when configuring common transmission waveform parameters in the RMSI, one embodiment is to configure transmission waveform parameters corresponding to DFT-s-OFDM in the RMSI, and all terminals transmit msg.3 using DFT-s-OFDM. This embodiment is relatively conservative, and the transmission efficiency (SE) of the terminal with better channel conditions will be lost. In one embodiment, the transmission waveform parameters corresponding to the CP-OPDM are configured in the RMSI, and all terminals use the CP-OPDM to send Msg.3. This embodiment is relatively aggressive, and at this time, the PAPR of the terminal that needs coverage enhancement may be 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 may transmit msg.3 based on different transmission waveforms. That is, the transmission waveform parameters corresponding to CP-OPDM are configured for the terminal with normal coverage, and the transmission waveform parameters corresponding to 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 flow chart illustrating a method of transmission waveform parameter determination according to an example embodiment. This embodiment can be implemented independently or in conjunction with any one or more embodiments of the present disclosure. As shown in fig. 2, the transmission waveform parameter determination method is used in a terminal and includes the following steps.

In step S11, first indication information is received.

In the embodiment of the present disclosure, the first indication information is used to indicate a transmission waveform parameter. Wherein the transmission waveform parameters include at least 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 used for transmitting the message are determined according to at least one of the status of the terminal and the indication information.

In the embodiment of the present disclosure, the state of the terminal at least includes 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 represents that the state of the terminal is the first state, and the second state terminal represents that the state of the terminal is the 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 power state and the second state terminal is a terminal having a low power state. This is, of course, merely an example and is not intended to be a specific limitation of the first and second states in this disclosure.

In the method for determining transmission waveform parameters provided in the embodiment of the present disclosure, different transmission waveform configuration parameters are configured for terminals in different states, so that the terminal can ensure a PAPR required by a terminal with poor coverage when sending a message, and can also ensure transmission efficiency of a terminal with good coverage.

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 Receiving Power (RSRP).

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

different types of terminals;

terminals of different versions; and

terminals of 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 flow chart illustrating a method of transmission waveform parameter determination according to an example embodiment. This embodiment can be implemented independently or in conjunction with any one or more embodiments of the present disclosure. As shown in fig. 3, the transmission waveform parameter determination method is used in a terminal and includes the following steps.

In step S21, second indication information is received.

In the embodiment of the present disclosure, the second indication information is used to indicate the terminal to determine the state of the terminal. And the terminal performs channel state measurement based on a second indication message sent by the network side, determines a reference signal measurement value, and further determines the state of the terminal 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 transmission of the waveform parameter is different from a message used by 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 is in the same indication message as the message used by the terminal to determine the state of the terminal.

In the embodiment of the present disclosure, the correspondence between the transmission waveform parameter, the Physical Random Access Channel (PRACH) set, and the state of the terminal may be as follows:

the first transmission waveform parameters correspond to a first PRACH set, which corresponds to a first state terminal. The second transmission waveform parameters correspond to a second set of PRACH that corresponds 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 completely different or not identical.

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

For example, referring to table 1, the terminal determines its own state according to the RSRP range, and the terminal sends msg.1 in 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 that is used by the terminal to subsequently send msg.3.

Therefore, it will be understood by those skilled in the art that the values of each of the elements in table 1 are independent embodiments.

In some embodiments of the present disclosure, the first indication message may further include transmission waveform parameter indication information used by the 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 the transmission waveform parameters applied by the terminal in one state based on the indication information included in the first indication message, and use the predefined transmission waveform parameters by the terminal in the other 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 a communication protocol.

In some embodiments of the present disclosure, for example, the first status terminal is a terminal with normal coverage, and the second status terminal is a terminal that needs coverage enhancement. The first indication message includes indication information indicating a transmission waveform parameter used by a normally covered terminal, which may be a transmission waveform parameter corresponding to CP-OFDM.
