Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a time slot format configuration method, a sensing device, a network side device, a communication system, a storage medium, and a computer program product. Background Art

[0002] Integration of Sensing and Communication (ISAC) is a key technology for 6G and other networks. ISAC technology can greatly improve the spectrum, energy, cost and efficiency of sensing and communication functions by utilizing the same frequency, waveform and infrastructure to extract target information from scattered echoes while achieving data transmission. For integration of sensing technology, in order to enable existing communication systems to have perception capabilities, the physical layer needs to allocate perception resources. Therefore, the existing communication frame format needs to be redesigned to meet the perception requirements. For example, in addition to the existing uplink and downlink communication time slots / symbols, it is necessary to configure perception time slots / symbol resources to support the use of perception-specific signal duplex modes and waveforms within these resources to provide continuous perception coverage. At present, the existing relevant communication protocols only support the configuration of uplink and downlink communication resources. Therefore, it is necessary to provide a technical solution for time slot format indication to support the new integration of sensing frame structure configuration. Summary of the invention

[0050] Figure 1 FIG. 1 is a flow chart of some embodiments of the time slot format configuration method according to the present disclosure. Figure 1 As shown, the time slot format configuration method is applied to a sensing device, including steps S101 and S102.

[0051] Step S101, receiving time slot format configuration information sent by a network side device; wherein the time slot format configuration information includes at least one time slot pattern information, and the time slot pattern information includes configuration parameters and configuration rules corresponding to the configuration parameters. The configuration parameters may include at least one of the number of sensing time slots, the number of sensing symbols, etc.

[0052] Step S102: configuring a frame structure pattern corresponding to an uplink wireless frame based on the time slot format configuration information.

[0053] The sensing device may be a variety of devices such as a smart phone, a car, and a drone, and the network side device may be a variety of devices such as a base station. The network side device may use a variety of messages or signaling to send time slot format configuration information, and the sensing device receives the time slot format configuration information sent by the network side device to configure a frame structure pattern corresponding to the uplink wireless frame. When the sensing device sends uplink information to the network side device, it generates an uplink wireless frame according to the frame structure pattern and sends it.

[0054] The time slot format configuration method disclosed in the present invention proposes a time slot format indication scheme suitable for communication perception integration technology, which can support the cellular system to send and receive perception signals in addition to uplink and downlink communications, and can provide continuous high-precision perception coverage; it can configure uplink and downlink communication time slots, symbols and perception time slots, symbols, etc., and by supporting multi-pattern flexible periodic configuration, the time slot format configuration has good flexibility; it can be modified based on existing protocols, the protocol continuity is good, and the increased signaling overhead is small.

[0055] In some embodiments, the configuration parameters may further include at least one of a pattern period, a number of downlink time slots, a number of downlink symbols, a number of uplink time slots, a number of uplink symbols, etc. For example, the sensing device receives time slot format configuration information sent by the network side device, the time slot format configuration information includes one or more time slot pattern information, each time slot pattern information includes a configuration parameter and a configuration rule corresponding to the configuration parameter.

[0056] The configuration parameters include at least one of the number of perception time slots, the number of perception symbols, the pattern period, the number of downlink time slots, the number of downlink symbols, the number of uplink time slots, the number of uplink symbols, the perception time slot index, the synaesthesia pattern period, etc.; the configuration rules include multiple rules for configuring the frame structure pattern based on the time slot format configuration information.

[0057] The pattern period is the period of the pattern that only contains uplink and downlink symbols or time slot configurations; the number of downlink time slots can be the number of consecutive downlink time slots at the start of the pattern; the number of downlink symbols can be the number of consecutive downlink symbols from the start of the next time slot of the last downlink time slot; the number of uplink time slots is the number of consecutive uplink time slots at the end of the pattern; the number of uplink symbols is the number of consecutive uplink symbols at the end of the previous time slot of all uplink time slots, wherein the values ​​of the number of downlink time slots, the number of downlink symbols, the number of uplink time slots, the number of uplink symbols, the number of perception time slots, the number of perception symbols, etc. can be 0.

[0058] In some embodiments, the configuration rule includes: in the frame structure pattern, the sensing time slot and / or the sensing symbol is located before the starting position of the uplink symbol, etc. The sensing time slot and / or the sensing symbol can be configured from the starting position of the uplink symbol forward. The following are some specific methods for pattern configuration based on configuration parameters and configuration rules.

[0059] Method 1-1: Configuration parameters may include the number of perception symbols and the number of first interval symbols, etc.; configuration rules include: the number of symbols between the end position of the perception symbol and the start position of the uplink symbol is the number of first interval symbols.

[0060] For example, only perception symbols are configured in the frame structure pattern, but perception time slots are not configured. In the frame structure pattern, continuous perception symbols are configured according to the number of perception symbols. The first interval symbol is G1, and G1 can be a plurality of symbols. The number of symbols spaced between the end position of the perception symbol and the start position of the uplink symbol is the number of G1 symbols, that is, the end position of the perception symbol is spaced from all uplink symbols by G1 symbols.

[0061] The number of G1 symbols can be 0 or non-zero. Figure 2A As shown in FIG. 1 , when the number of G1 symbols is 0, there is no spacing symbol between the end position of the perception symbol and the start position of the uplink symbol in the frame structure pattern. Figure 2B As shown, when the number of G1 symbols is not 0, in the frame structure pattern, the end position of the perception symbol and the start position of the uplink symbol are separated by G1 symbols, and the number of G1 symbols can be configured, for example, 1, 2, 3, etc.

[0062] Method 1-2: The configuration parameters also include the number of perception time slots, etc.; the configuration rules include: the end position of the perception time slot is connected to the starting position of the perception symbol, and the number of symbols between the end position of the perception symbol and the starting position of the uplink symbol is the first interval symbol number.

[0063] For example, in the frame structure pattern, to configure the sensing symbol and the sensing time slot, the sensing symbol can be configured first. Figure 3 As shown, in the frame structure pattern, continuous sensing symbols and sensing time slots are configured according to the number of sensing symbols and the number of sensing time slots; the first interval symbol is G1, and G1 can be a variety of symbols.

[0064] There is a G1 symbol between the end position of the perception symbol and the start position of the uplink symbol, and the number of G1 symbols can be configured, such as 1, 2, 3, etc. There is no interval between the perception symbol and the perception time slot, and the end position of the perception time slot is connected to the start position of the perception symbol.

[0065] Method 1-3: The configuration rule includes: the end position of the sensing symbol is connected to the start position of the sensing time slot, etc. For example, in the frame structure pattern, the sensing symbol and the sensing time slot are configured, and the sensing time slot can be configured first. Figure 4 As shown, in the frame structure pattern, continuous sensing symbols and sensing time slots are configured according to the number of sensing symbols and the number of sensing time slots, there is no gap between the sensing symbols and the sensing time slots, and the end position of the sensing symbol is connected to the start position of the sensing time slot.

[0066] Method 1-4: The number of perception symbols includes: the first number of perception symbols and the second number of perception symbols, etc.; the configuration rules include: the end position of the second perception symbol is connected to the starting position of the perception time slot, the revelation position of the first perception symbol is connected to the end position of the perception time slot, and the number of symbols spaced between the end position of the first perception symbol and the starting position of the uplink symbol is the first interval symbol number.

[0067] For example, in the frame structure pattern, the first sensing symbol, the sensing time slot and the second sensing symbol are configured. The first sensing symbol may be configured first, then the sensing time slot may be configured, and finally the second sensing symbol may be configured. Figure 5 As shown, in the frame structure pattern, continuous first perceptual symbols, perceptual time slots, and second perceptual symbols are configured according to the first perceptual symbol quantity, the perceptual time slot quantity, and the second perceptual symbol quantity.

[0068] The first interval symbol is G1, the end position of the second perception symbol is connected to the start position of the perception time slot, the start position of the first perception symbol is connected to the end position of the perception time slot, and there is no interval between the first perception symbol and the perception time slot, and between the perception time slot and the second perception symbol. The end position of the first perception symbol and the start position of the uplink symbol are separated by G1 symbols, and the number of G1 symbols can be configured, for example, 1, 2, 3, etc.

[0069] In some embodiments, the configuration rules include: in the frame structure pattern, the sensing time slot and / or the sensing symbol are located after the termination position of the downlink symbol, etc. In the frame structure pattern, the sensing time slot and / or the sensing symbol can be configured backward from the downlink symbol. The following are some specific methods for pattern configuration based on configuration parameters and configuration rules.

[0070] Method 2-1: Configuration parameters include: number of perception symbols, number of second interval symbols, etc.; configuration rules include: the number of symbols between the starting position of the perception symbol and the ending position of the downlink symbol is the number of second interval symbols.

[0071] For example, in the frame structure pattern, only the sensing symbols are configured, but not the sensing time slots. Figure 6 As shown, the second interval symbol is G2, and G2 can be a variety of symbols. In the frame structure pattern, continuous perception symbols are configured according to the number of perception symbols, and the number of symbols between the starting position of the perception symbol and the end position of the downlink symbol is the number of G2 symbols, and the number of G2 symbols can be 0 or not 0.

[0072] Method 2-2: The configuration parameters also include the number of perception time slots, etc.; the configuration rules include: the end position of the perception symbol is connected to the starting position of the perception time slot, and the number of symbols between the starting position of the perception symbol and the end position of the downlink symbol is the second interval symbol number.

[0073] For example, in the frame structure pattern, to configure the sensing symbol and the sensing time slot, the sensing symbol can be configured first. Figure 7 As shown, in the frame structure pattern, continuous sensing symbols and sensing time slots are configured according to the number of sensing symbols and the number of sensing time slots; the second interval symbol is G2, and G2 can be a variety of symbols.

[0074] The end position of the perception symbol is connected to the start position of the perception time slot, and the number of symbols between the start position of the perception symbol and the end position of the downlink symbol is the number of G2 symbols. There is no interval between the perception symbol and the perception time slot. The number of G2 symbols can be configured, for example, 1, 2, 3, etc.

[0075] Method 2-3: The configuration rule includes: the sensing time slot is located after the end position of the downlink symbol, and the end position of the sensing time slot is connected to the start position of the sensing symbol. For example, in the frame structure pattern, the sensing symbol and the sensing time slot are configured, and the sensing time slot can be configured first. Figure 8 As shown, in the frame structure pattern, continuous perception symbols and perception time slots are configured according to the number of perception symbols and the number of perception time slots, the perception time slot is located after the end position of the downlink symbol, and the end position of the perception time slot is connected to the starting position of the perception symbol, and there is no interval between the perception symbol and the perception time slot.

[0076] Method 2-4: The number of perception symbols includes: the number of third perception symbols and the number of fourth perception symbols, etc.; the configuration rules include: the end position of the third perception symbol is connected to the starting position of the perception time slot, the starting position of the fourth perception symbol is connected to the end position of the perception time slot, and the number of symbols between the starting position of the third perception symbol and the end position of the downlink symbol is the second interval symbol number.

[0077] For example, in the frame structure pattern, the third perception symbol, the perception time slot and the fourth perception symbol are configured. The third perception symbol may be configured first, then the perception time slot may be configured, and finally the fourth perception symbol may be configured. Fig. 9 As shown, in the frame structure pattern, continuous third perceptual symbols, perceptual time slots, and fourth perceptual symbols are configured according to the third perceptual symbol quantity, the perceptual time slot quantity, and the fourth perceptual symbol quantity.

[0078] The second interval symbol is G2, the end position of the third perception symbol is connected to the start position of the perception time slot, the start position of the fourth perception symbol is connected to the end position of the perception time slot, and there is no interval between the third perception symbol and the perception time slot, and between the perception time slot and the fourth perception symbol. The start position of the third perception symbol and the end position of the downlink symbol are separated by G2 symbols, and the number of G2 symbols can be configured, for example, 1, 2, 3, etc.

[0079] In some embodiments, the configuration parameters also include perception time slot index information, perception symbol configuration information, etc.; the configuration rules include: determining the time slot of the perception symbol according to the perception time slot index information, and, in the frame structure pattern, determining the position information corresponding to the time slot of the perception symbol according to the perception symbol configuration information.

[0080] For example, in the frame structure pattern, the perception symbol is configured according to the time slot index number. In the frame structure pattern, the time slots are numbered sequentially starting from 0. The time slot index containing the perception symbol is determined by one or more perception time slot index information, and then the symbol position of the perception symbol in the time slot is determined by the perception symbol configuration information of the time slot. The perception symbol configuration cannot rewrite the symbols configured as uplink and downlink in the pattern.

[0081] like Fig. 10A As shown, in each pattern period, the time slot index number starts from 0. When the received perception time slot index number set (perception time slot index information) is {k1, k2}, it is determined that the corresponding time slot is configured as a perception time slot containing perception resources. When there is a time slot number in the received perception time slot index number set that conflicts with the configured uplink or downlink time slot, the time slot number is invalid. For example, if the network side device configures {0, k1, k2} as a perception time slot, since time slot 0 has been configured as a downlink time slot, this time slot cannot be configured as a perception time slot.

[0082] In the time slot where the perception time slot is configured, the specific position and number of the perception symbols can be determined by the perception symbol configuration information of the time slot. For example, for the perception time slot with the time slot number k1, the perception symbol configuration information sent by the receiving network side device is used to indicate the time slot, for example, the perception symbol configuration information is the perception symbol index, etc., and the index number in the time slot still starts from 0. When the perception symbol index set is {0, 1, 2}, the first three symbols in the time slot are determined to be perception symbols, such as Fig. 10B shown.

[0083] In the frame structure pattern, the perception symbols may be configured according to the time slot index numbers in the pattern. The following are some specific methods for configuring the pattern based on configuration parameters and configuration rules.

[0084] Method 3-1: The perception time slot index information includes: a first index number set, etc.; the perception symbol configuration information is associated with the first index number set. For example, one or more perception time slot index numbers are configured, and all perception time slots share a set of perception symbol configurations. The perception time slot index information includes an index number set (the first index number set), and the perception symbol configuration is effective for the time slots corresponding to the index number set at the same time, that is, the configuration information is associated with the index number set.

[0085] The sensing symbol configuration is effective for the time slots corresponding to the index set at the same time, which means that the number and position configurations of the sensing symbols are the same in all time slots configured as sensing time slots, that is, the symbol index set is for all sensing time slots, rather than corresponding to a specific sensing time slot. Fig. 10B As shown, the perceptual symbol index set {0, 1, 2} is effective for both the k1 time slot and the k2 time slot.

[0086] Method 3-2: The perceptual time slot index information includes: a second index number set, etc.; the perceptual symbol configuration information includes: a perceptual symbol configuration set; the index information in the second index number set corresponds one-to-one to the configuration information in the perceptual symbol configuration set.

[0087] For example, one or more perception time slot index numbers are configured, and perception symbols are configured separately for all perception time slots. The perception time slot index configuration information includes an index number set (a second index number set), and the perception symbol configuration information includes a perception symbol configuration set. The indexes in the index number set correspond to the configurations in the perception symbol configuration set one by one; each perception symbol configuration in the perception symbol configuration set is effective for a time slot corresponding to an index in the index number set.

[0088] Each perception symbol configuration in the perception symbol configuration set is effective for the time slot corresponding to an index in the index number set, which means that in all time slots configured as perception time slots, the number and position configurations of the perception symbols are not necessarily the same, that is, the symbol index set is for a certain perception time slot, rather than corresponding to all perception time slots. For example, the perception symbol index set {0, 1, 2} is effective for the k1 time slot, and the number and position of the perception symbols in the k2 time slot are indicated by another symbol index set. The number of perception time slots is the same as the configuration information of the perception symbol. Compared with method 3-1, method 3-2 has the advantage of more flexible configuration and the disadvantage of greater signaling overhead.

[0089] In some embodiments, two frame structure patterns may be configured, including a first pattern and a second pattern. In the first pattern, one or more time slot format configuration methods in the above embodiments may be used to configure a first number of perceived symbols, or a first number of perceived symbols and a first number of perceived time slots.
