Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to an information determination method and apparatus, and a computer storage medium. Background Technology

[0002] The vehicle-to-everything (V2X) system adopts sidelink (SL) transmission technology based on Long Term Evolution (LTE) - Device to Device (D2D). Unlike the traditional LTE system where communication data is received or sent through base stations, the V2X system uses direct terminal-to-terminal communication, thus achieving higher spectrum efficiency and lower transmission latency.

[0003] The 3rd Generation Partnership Project (3GPP) Rel-14 standardized vehicle-to-everything (V2X) technology, defining two transmission modes: Mode 3 and Mode 4. In Mode 3, the terminal's transmission resources are allocated by the base station. In Mode 4, the terminal uses a sensing + reservation method to determine transmission resources.

[0004] In New Radio (NR)-V2X, supporting autonomous driving requires higher standards for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, wider coverage, and more flexible resource allocation. To meet these requirements, NR-V2X necessitates the introduction of multi-antenna transmission technology. Beamforming in multi-antenna transmission technology can improve coverage and reliability. The data transmitter selects the optimal beam from multiple candidate beams through any of the following methods:

[0005] Method 1: The transmitting end needs to perform beam scanning and use different beams for transmission; the receiving end receives the data transmitted by each beam, and can select the beam with the best transmission quality as the optimal beam, and feed back the index value of the optimal beam to the transmitting end; in subsequent data transmission, the transmitting end can use the optimal beam for data transmission.

[0006] Method 2: The receiving end transmits multiple reference signals in an omnidirectional manner, and the transmitting end receives each reference signal with a different beam. The beam corresponding to the reference signal with the best channel quality is selected as the transmitting beam, and the selected optimal beam is used for data transmission in subsequent data transmission.

[0007] In the second method described above, how the transmitting and receiving ends determine the number of reference signals is a problem that needs to be solved. Summary of the Invention

[0116] To gain a more detailed understanding of the features and technical content of the embodiments of the present invention, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of the present invention.

[0117] To facilitate understanding of the technical solutions of the embodiments of the present invention, the following will explain and describe Mode 3 and Mode 4 in the Internet of Vehicles.

[0118] Mode 3: such as Figure 1 As shown, the transmission resources of the vehicle-mounted terminal are allocated by the base station (such as the evolved NodeB in LTE). Specifically, the base station sends a control message indicating the grant resources to the vehicle-mounted terminal via the downlink (DL). Then, the vehicle-mounted terminal transmits data on the SL according to the resources allocated by the base station. In Mode 3, the base station can allocate resources for a single transmission or for semi-static transmission to the vehicle-mounted terminal.

[0119] Mode 4: such as Figure 2 As shown, the vehicle-mounted terminal adopts a listening + reservation transmission method. The vehicle-mounted terminal obtains the set of available transmission resources from the resource pool through listening, and then randomly selects a resource from this set for data transmission. Because the services in the vehicle-to-everything (V2X) system have periodic characteristics, the vehicle-mounted terminal typically adopts a semi-static transmission method. That is, after selecting a transmission resource, the vehicle-mounted terminal will continuously use that resource for multiple transmission cycles, thereby reducing the probability of resource reselection and resource conflicts. The vehicle-mounted terminal carries information about reserving resources for the next transmission in the control information of this transmission. This allows other terminals to determine whether the resource has been reserved and used by the vehicle-mounted terminal by detecting its control information, thus reducing resource conflicts.

[0120] It should be noted that in LTE-V2X, mode 3 indicates that the transmission resources of the vehicle terminal are allocated by the base station, and mode 4 indicates that the transmission resources of the vehicle terminal are selected autonomously by the terminal. In NR-V2X, new transmission modes can be defined, and this invention does not limit them.

[0121] NR-V2X requires the introduction of multi-antenna transmission technology, which offers several advantages:

[0122] 1) Higher transmission rate: By using multiple antennas for multiplexing transmission, multiple data streams can be transmitted on the same time and frequency resources, thereby increasing the transmission rate.

[0123] 2) Greater coverage and higher reliability: Beamforming technology can concentrate energy into a very narrow beam, thereby improving the signal-to-interference-plus-noise ratio (SINR) at the receiver, which can increase the success rate of reception or increase the transmission distance.

[0124] In one embodiment of the present invention, the reference signal transmitting end (i.e., the first terminal) transmits N first reference signals (also called beam training reference signals or beam scanning reference signals), and the reference signal receiving end (i.e., the second terminal) receives the corresponding N first reference signals using N different channels (also called beams), and selects the optimal channel (i.e., the target channel) for data transmission.

[0125] The technical solution of this invention can determine the number of first reference signals in a vehicle-to-everything (V2X) system. Specifically, the number of first reference signals is explicitly or implicitly indicated by the Physical Side Link Control Channel (PSCCH) of the reference signal transmitter. Alternatively, the first terminal and the second terminal can also determine the number of first reference signals through pre-configured information or network configuration information.

[0126] All the technical solutions of the embodiments of the present invention are applicable not only to vehicle networking systems, but also to other end-to-end communication systems. The terminal in the embodiments of the present invention can be an in-vehicle terminal, a handheld terminal, a PDA (Personal Digital Assistant), a wearable terminal, etc. The network in the embodiments of the present invention can be an NR network, an LTE network, etc.

[0127] Figure 3 This is a flowchart illustrating the information determination method according to an embodiment of the present invention. Figure 1 ,like Figure 3As shown, the information determination method includes the following steps:

[0128] Step 301: The first terminal determines that the number of the first reference signals is N, where N is a positive integer.

[0129] In this embodiment of the invention, the types of the first terminal and the second terminal are not limited, and can be devices such as vehicle terminals, mobile phones, and laptops.

[0130] In this embodiment of the invention, the first terminal determines the number of the first reference signals as N based on pre-configured information, network configuration information, or by a self-selected method.

[0131] Step 302: The first terminal sends a control channel and N first reference signals to the second terminal, wherein the control channel is used by the second terminal to determine that the number of the first reference signals is N, so as to receive the N first reference signals through the N channels respectively.

[0132] In this embodiment of the invention, the first terminal transmits N first reference signals in an omnidirectional manner, wherein the N first reference signals are time-division multiplexed. The second terminal receives the N first reference signals through N channels (also called beams).

[0133] In this embodiment of the invention, the first terminal sends a control channel to the second terminal, the control channel being used by the second terminal to determine that the number of the first reference signals is N. The transmission resources of the control channel of the first terminal and the first reference signals are time-division multiplexed.

[0134] For example: The first terminal transmits the Physical Side Link Control Channel (PSCCH) on subframe n, and transmits the first reference signal on subframe n+m, where m is a positive integer. Alternatively, the first terminal transmits the PSCCH on symbols p to p+P-1, where P represents the total number of symbols used by the PSCCH, and begins transmitting the first reference signal on symbol p+P-1+q, where q is a positive integer. If the first terminal transmits N first reference signals, then the first terminal transmits the first first reference signal on symbol p+P-1+q, and the number of symbols between two adjacent first reference signals can be predefined or configured by the network.

[0135] In this embodiment of the invention, the control channel of the first terminal is used by the second terminal to determine that the number of the first reference signals is N, and has the following implementation:

[0136] Method 1: The number of the first reference signals is explicitly indicated through the control channel of the first terminal.

[0137] The control channel includes first indication information, which is used to determine that the number of the first reference signals is N.

[0138] For example, the PSCCH of the first terminal uses K bits to represent the value of N, where K is a positive integer, such as 2, 3, 4, etc. The second terminal obtains the first indication information from the control channel of the first terminal. After determining the value of N based on the first indication information, it can select a corresponding number (i.e., N) of channels to receive the N first reference signals in the time domain.

[0139] Method 2: The number of the first reference signals is implicitly indicated through the control channel of the first terminal.

[0140] Here, before sending the control channel, the first terminal performs the following processing on the control channel: scrambling the control channel with specific scrambling code information (such as first scrambling code information); and / or masking the control channel with specific masking information (such as first masking information); and / or encoding the control channel with specific encoding / decoding information (such as first encoding / decoding information). Correspondingly, after receiving the control channel, the second terminal needs to decode the control channel with the specific encoding / decoding information (such as first encoding / decoding information); and / or demask the control channel with the specific masking information (such as first masking information); and / or descramble the control channel with the specific scrambling code information (such as first scrambling code information).

[0141] In this embodiment of the invention, a first correspondence is established between the first scrambling information and the value of N, or a second correspondence is established between the first mask information and the value of N, or a third correspondence is established between the first encoding / decoding information and the value of N; thus, the second terminal can implicitly know the value of N based on the first scrambling information, the first mask information, or the first encoding / decoding information corresponding to the control information. This is described in detail below:

[0142] 1.1) The first terminal determines first scrambling code information corresponding to the value of N based on a first correspondence; the first terminal uses the first scrambling code information to scramble the control channel; wherein, the first scrambling code information corresponding to the control channel is used to determine that the number of the first reference signals is N. In one embodiment, the first terminal determines the first correspondence based on pre-configured information or network configuration information.

[0143] For example, Table 1 shows the first correspondence between the first scrambling code information and the value of N. Assuming the value of N is 4, it can be seen from Table 1 that the first scrambling code information corresponding to 4 is scrambling code sequence 1.

[0144] First scrambling code information The value of N Scrambling sequence 1 4 Scrambling sequence 2 8 Scrambling sequence 3 16 Scrambling sequence 4 32

[0145] Table 1

[0146] 1.2) The first terminal determines the first mask information corresponding to the value of N based on the second correspondence; the first terminal uses the first mask information to mask the control channel; wherein, the first mask information corresponding to the control channel is used to determine that the number of the first reference signals is N. In one embodiment, the first terminal determines the second correspondence according to pre-configured information or network configuration information.

[0147] For example, Table 2 shows the second correspondence between the first mask information and the value of N. Assuming the value of N is 8, it can be seen from Table 2 that the first mask information corresponding to 8 is mask sequence 2.

[0148] First mask information The value of N Mask sequence 1 4 Mask sequence 2 8 Mask sequence 3 16 Mask sequence 4 32

[0149] Table 2

[0150] 1.3) The first terminal determines the first encoding / decoding information corresponding to the value of N based on the third correspondence; the first terminal uses the first encoding / decoding information to encode the control channel; wherein, the first encoding / decoding information corresponding to the control channel is used to determine that the number of the first reference signals is N. In one embodiment, the first encoding / decoding information includes at least one of the following: DMRS sequence, cyclic shift, OCC sequence, root sequence. In one embodiment, the first terminal determines the third correspondence based on pre-configured information or network configuration information.

[0151] Taking the first codec information including the DMRS sequence as an example, Table 3 shows the third correspondence between the first codec information and the value of N. Assuming the value of N is 16, it can be seen from Table 3 that the first codec information corresponding to 16 is the DMRS sequence 3.

[0152] First encoding / decoding information The value of N DMRS Sequence 1 4 DMRS Sequence 2 8 DMRS sequence 3 16 DMRS sequence 4 32

[0153] Table 3

[0154] In this embodiment, the number of first reference signals for the first terminal can be pre-configured or network-configured (e.g., in mode 3, the network configures the number of first reference signals for the first terminal) or selected autonomously. The first terminal selects an appropriate number of first reference signals and explicitly or implicitly carries the number of first reference signals in the control channel. The second terminal obtains the corresponding number of reference signals by receiving the control channel of the first terminal and receives the reference signals with the corresponding number of beams. Furthermore, the control channel and the first reference signals of the first terminal are time-division multiplexed. For example, the control channel is transmitted in subframe or time slot n, and the first reference signal is transmitted in subframe or time slot n+m, where m is a positive integer; another example is that the control channel is transmitted in symbol n, and the first reference signal is transmitted in symbol n+m, where m is a positive integer. In practical applications, the control channel and the first reference signals can be within one subframe or time slot, or they can span multiple subframes or time slots.

[0155] Figure 4 This is a flowchart illustrating the information determination method according to an embodiment of the present invention. Figure 2 ,like Figure 4 As shown, the information determination method includes the following steps:

[0156] Step 401: The second terminal determines that the number of the first reference signals sent by the first terminal is N, where N is a positive integer.

[0157] In this embodiment of the invention, the types of the first terminal and the second terminal are not limited, and can be devices such as vehicle terminals, mobile phones, and laptops.

[0158] In this embodiment of the invention, the second terminal determines that the number of first reference signals sent by the first terminal is N, which can be achieved by any of the following two methods:

[0159] Method 1: The second terminal determines the number of first reference signals sent by the first terminal as N based on pre-configured information or network configuration information.

[0160] Method 2: The second terminal receives the control channel sent by the first terminal, and determines the number of first reference signals sent by the first terminal as N based on the control channel, where N is a positive integer.

[0163] Specifically, the second terminal receives a control channel sent by the first terminal and obtains first indication information from the control channel; the second terminal determines the number of the first reference signals based on the first indication information.

[0164] 2.2) The number of the first reference signals is implicitly indicated through the control channel of the first terminal.

[0167] In one embodiment, the first encoding / decoding information includes at least one of the following: DMRS sequence, cyclic shift, OCC sequence, and root sequence.

[0168] In one embodiment, the second terminal determines the third correspondence based on pre-configured information or network configuration information.

[0169] 2.22) The second terminal receives the control channel sent by the first terminal and performs demasking processing on the control channel using the first mask information; the second terminal determines the value of N corresponding to the first mask information based on the second correspondence relationship, as the number of the first reference signals.

[0170] In one embodiment, the second terminal determines the second correspondence based on pre-configured information or network configuration information.

[0172] In one embodiment, the second terminal determines the first correspondence based on pre-configured information or network configuration information.

[0173] Step 402: The second terminal receives N first reference signals sent by the first terminal through N channels respectively, wherein the transmission resources of different channels are time-division multiplexed.

[0174] In this embodiment of the invention, the second terminal receives N first reference signals sent by the first terminal through N channels, which is achieved in the following way: the second terminal uses beamforming technology to form N beams, wherein the transmission resources of different beams are time-division, and one beam represents one channel. The second terminal uses beam polling to receive the N first reference signals sent by the first terminal through the N beams (i.e., channels). Here, the N first reference signals are time-division, and the transmission resources can be time-frequency resources.

[0175] For example, the first terminal sends N first reference signals, each of which occupies one orthogonal frequency division multiplexing (OFDM) symbol. After the second terminal determines the value of N, it uses N beams to receive the N first reference signals. That is, the second terminal uses N beams to receive the first reference signals on the N symbols where the first reference signals are located.
