Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal sending method, receiving method, device, equipment and storage medium. Background Art

[0002] In the base station's self-transmitting and self-receiving sensing mode, both the Normal Cyclic Prefix (NCP) and the Extended Cyclic Prefix (ECP) have corresponding maximum sensing distances. For long-distance target detection, multipath super CP will cause inter-symbol interference (ISI) of the sensing signal, and similarly there will be inter-channel interference (ICI); there is a conflict between the reception of the sensing signal and the transmission of the communication signal caused by multipath super CP. It can be seen that sending sensing signals based on NCP will severely limit the sensing coverage, affect the sensing accuracy, and increase the site deployment cost. Summary of the invention

[0120] In an embodiment of the present application, the first symbol includes: a symbol for sending the perception signal; the second symbol includes: an uplink (UL) symbol or a downlink (DL) symbol on a flexible time slot; the third symbol includes: a flexible symbol, and the position of the flexible symbol is the position of the uplink and downlink conversion.

[0121] In the embodiment of the present application, sending the perception signal on a symbol before a flexible symbol in a flexible time slot includes:

[0122] The perception signal is sent on a first symbol; the first symbol occupies the last one or more second symbols before the flexible symbol in the flexible time slot and occupies one or more flexible symbols; the flexible symbol is located after the second symbol;

[0131] The number of flexible symbols occupied by the first symbol =

[0132]

[0133] indicates a round-up operation; or,

[0134]

[0135] Indicates a round-up operation.

[0136] In one embodiment, in actual application, the perception signal may be sent in the last one or more DL symbols before the uplink and downlink conversion in the flexible time slot, and the perception signal adopts ECP, and the communication signal adopts NCP. Figure 2 As shown:

[0137] Since the first symbol of the sent perception signal using ECP ( Figure 2 The time length of the symbol represented by "S" shown in the figure) is greater than the time length of the symbol for sending the communication signal (using NCP). Therefore, the time length of the first symbol is increased by X*(ECP-NCP) compared with the time length of the symbol for sending the communication signal, and occupies a part of the flexible symbol ( Figure 2 The number of flexible symbols occupied by the first symbol can be expressed as: Indicates a round-up operation.

[0138] In the embodiment of the present application, sending the perception signal on a symbol after a flexible symbol in a flexible time slot includes:

[0139] The perception signal is sent on a first symbol; the first symbol occupies one or more second symbols after the flexible symbol in the flexible time slot, and occupies one or more flexible symbols; the flexible symbol is located before the second symbol;

[0140] The number of second symbols and / or flexible symbols occupied by the first symbol is related to at least one of the following parameters:

[0149]

[0150] indicates a round-up operation; or,

[0151]

[0152] Indicates a round-up operation.

[0153] In one embodiment, in actual application, the perception signal may be sent in one or more UL symbols after uplink / downlink conversion in a flexible time slot, the perception signal uses ECP, and the communication signal uses NCP. Figure 3 As shown:

[0154] On the one hand, the perception signal adopts ECP. Since the first symbol ( Figure 3 The time length of the symbol represented by "S" shown in the figure) is greater than the time length of the symbol for sending the communication signal (using NCP). Therefore, relative to the original NCP frame structure, the first symbol needs to be sent in advance by the time length of (ECP-NCP). On the other hand, in order to prevent the perception signal from being too delayed and affecting the transmission of the symbols of the communication signal sent later, the first symbol needs to be sent in advance by the time length of (ECP-NCP). Therefore, the perception signal needs to be sent in advance by 2*(ECP-NCP) time length, occupying a part of the flexible symbol ( Figure 3 Therefore, when sending X first symbols, the first symbol needs to be sent in advance by 2X*(ECP-NCP) time length. Indicates a round-up operation.

[0155] In the embodiment of the present application, sending the perception signal in an uplink timeslot or a downlink timeslot includes:

[0156] The uplink time slot or the downlink time slot is divided into N sub-time slots;

[0157] The perception signal is sent on X sub-time slots among N sub-time slots, and the communication signal is sent on Y sub-time slots among N sub-time slots; wherein,

[0158] The X sub-slots include six symbols, and the Y sub-slots include seven symbols.

[0159] It can be seen that for the NCP frame structure, one time slot has 14 symbols; for the ECP frame structure, one time slot has 12 symbols. In one embodiment of the present application, one uplink time slot or downlink time slot is divided into N sub-slots, of which X sub-slots use the ECP mode to send perception signals, and Y sub-slots use the NCP mode to send communication signals. The X sub-slots for sending ECP perception signals contain a total of 6 symbols; the Y sub-slots for sending NCP communication signals contain a total of 7 symbols; therefore, there are 13 symbols in one time slot. Within every 0.5ms, the CP length of the first communication orthogonal frequency division multiplexing (OFDM) symbol is 5.21μs, and the CP length of the 2nd to 7th OFDM symbols is 4.69μs. The 7 symbols for sending communication signals may be discontinuous. In actual application, such as Figure 4 As shown, the symbol represented by "S" is the symbol for sending a perception signal, and the symbol represented by "C" is the symbol for sending a communication signal. Figure 4 Two implementations of the frame structure are given. In the second implementation, the 7 symbols of the communication signal sent are discontinuous.

[0160] In the embodiment of the present application, sending the perception signal in an uplink timeslot or a downlink timeslot includes:

[0161] The symbol position where the perception signal is sent in the uplink time slot or the downlink time slot is indicated in a bitmap form.

[0162] In the embodiment of the present application, in actual application, the network may instruct the terminal, or the terminal may instruct the network to sense the symbol position of the signal sent in the uplink time slot or the downlink time slot, so that the terminal or the network can determine the symbol time position of the communication signal and perform frame structure alignment. For example:

[0163] It is indicated in the form of a 13-bit bitmap, for example, 0000001111111, where 0 represents sending an ECP perception signal and 1 represents sending an NCP communication signal.

[0166] In one uplink time slot or downlink time slot, m symbols are used to send n perception signals; wherein,

[0167] The time length of the m symbols is greater than the length of the n perception signals;

[0168] The perception signal takes a first moment position as a starting moment; the first moment position is a starting position of m symbols, or the first moment is any moment among the m symbols.

[0169] Here, in practical application, considering that the transmission of the perception signal may not require 6 symbols, for example, only 1-2 symbols are needed, at this time, m symbols (for example: communication OFDM symbols) can be reserved for sending n perception signals using ECP, and the time length of m symbols must be greater than the length of n perception signals using ECP. The first time position can be the starting position of the symbol for sending the communication signal, and the last remaining time domain position in the m symbols (the time domain position occupied by the signal that is not informed) can be reserved as a protection interval, such as Figure 5 The guard interval (Guard) shown in is used to reduce the interference of the perception signal on the communication signal.

[0170] In the embodiment of the present application, the method further includes:
