Description

Processing method and device, communication equipment, communication system, and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to processing methods and devices, communication equipment, communication systems, and storage media. Background Art

[0002] In a communication system, a terminal typically switches between different transmission schemes. For example, a terminal typically dynamically switches between single transmission reception point (STRP) transmission and multiple transmission reception point (MTRP) transmission. The bit width of an indication field used to indicate an association relationship between ports in downlink control information (DCI) signaling during STRP transmission differs from the bit width of an indication field used to indicate an association relationship between ports in DCI signaling during MTRP transmission. This results in a difference in the DCI bit width during STRP transmission and the DCI bit width during MTRP transmission, introducing uncertainty into the DCI size. This affects the stability and efficiency of the terminal when decoding DCI in scenarios where the transmission scheme is dynamically switched.

[0038] In a first aspect, an embodiment of the present disclosure provides a processing method, the method comprising:

[0039] The first device determines a first width and a second width; wherein the first width is a bit width required for a first indication field of the first signaling in the first transmission scheme, and the second width is a bit width required for the first indication field in the second transmission scheme; wherein the first indication field is used to indicate an association relationship between different ports;

[0040] The first width is different from the second width, and the first device performs a first operation to determine the first signaling to be sent in the first transmission scheme and / or the first signaling to be sent in the second transmission scheme; wherein the first operation is used to make the bit width of the first signaling to be sent in the first transmission scheme the same as the bit width of the first signaling to be sent in the second transmission scheme.

[0041] In the above embodiment, when the first device determines that the first width required for the first indication field of the first signaling in the first transmission scheme is different from the second width required for the first indication field in the second transmission scheme, the first device performs a first operation to make the width of the first signaling to be sent in the first transmission scheme the same as the width of the first signaling to be sent in the second transmission scheme. It can be seen from this that in the embodiment of the present disclosure, the width of the first signaling actually sent by the first device in the first transmission scheme will be the same as the width of the first signaling actually sent in the second transmission scheme, thereby ensuring that the width of the first signaling sent under different transmission schemes is consistent. Even if the transmission scheme is switched, since the width of the first signaling sent under different transmission schemes is consistent, the receiving device of the first signaling (i.e., the subsequent second device) does not need to determine which transmission scheme it currently corresponds to after receiving the first signaling. Instead, it can first traverse the width required for the first indication field of the first signaling in each transmission scheme, and then use the same determination method as the first device to determine the same width of the first signaling actually sent in different transmission schemes. Afterwards, the second device will demodulate the first signaling based on the same width of the first signaling actually sent in different transmission schemes, thereby avoiding the second device from performing blind detection on the first signaling, ensuring stability and efficiency when decoding the first signaling, and thereby ensuring stability and efficiency of signaling transmission.

[0201] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other processing methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0202] To achieve higher throughput and more reliable transmission performance in communication systems, a transmission scheme based on simultaneous transmission across multiple panels (STxMP) has been introduced. In R18 multi-panel (antenna) uplink transmission, STxMP supports scheduling the physical uplink shared channel (PUSCH) using space division multiplexing (SDM) or single frequency network (SFN) transmission schemes in MTRP transmission based on S-DCI. Furthermore, dynamic switching between STRP and MTRP is supported in STxMP transmission. Therefore, network devices typically indicate whether STRP or MTRP transmission is currently in progress in the dynamic switching indicator field of the DCI (e.g., the sounding reference signal resource set indicator field (SRS resource set indicator)). However, since the width of the indication field used to indicate the association relationship between ports in the DCI signaling during STRP transmission is different from the width of the indication field used to indicate the association relationship between ports in the DCI signaling during MTRP transmission, the DCI width during STRP transmission is also different from the DCI width during MTRP transmission. However, when demodulating DCI, the terminal usually needs to verify the DCI based on the width of the DCI, and the way the terminal knows the width of the DCI is: the terminal needs to first demodulate the dynamic switching indication field in the DCI to determine whether it is currently a STRP transmission or an MTRP transmission, and then determine the width of the indication field in the DCI indicating the association relationship between ports in combination with other scheduling parameters, and then determine the width of the DCI. As a result, the terminal will not know the width of the DCI and the width of the indication field in the DCI indicating the association relationship between ports before demodulating the DCI, which will cause the terminal to perform blind detection on the DCI, which will waste resources, increase demodulation delay, and affect communication efficiency.

[0203] FIG2A is an interactive diagram of a processing method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a processing method for a communication system 100, the method comprising:

[0204] Step 2101: The first device 101 determines a first width and a second width.

[0205] Optionally, the first device 101 may be a network device.

[0206] Optionally, in some embodiments, the first width is the bit width required for the first indication field of the first signaling in the first transmission scheme, and the second width is the bit width required for the first indication field in the second transmission scheme.

[0207] Optionally, in some embodiments, the first signaling may include DCI signaling; optionally, the DCI signaling may include at least one of the following: DCI format 0_1; DCI format 0_2, etc.

[0208] The first transmission scheme may include: STRP transmission based on simultaneous transmission across multiple panels (STxMP) transmission; the second transmission scheme may include: space division multiplexing (SDM) transmission or single frequency network (SFN) transmission based on MTRP in STxMP transmission. Optionally, the first device 101 may configure STxMP transmission as one of the {SDM, SFN} modes through radio resource control (RRC) signaling.

[0209] The first indication field can be used to indicate the association relationship between different ports. For example, the first indication field can be used to indicate the association relationship between a demodulation reference signal (DMRS) port and a phase tracking reference signal (PTRS) port.

[0210] Optionally, in some embodiments, the first device 101 can determine the first width in a variety of ways, which is not limited in this disclosure. For example, the first device 101 can determine the first width through a first parameter. The first parameter can be a related parameter under the first transmission scheme, and the first parameter can be used to configure the transmission mode of the signal in the first transmission scheme, or the first parameter can be used to indicate the configuration parameters related to transmission in the first transmission scheme; for example, the first parameter can be the maximum number of layers corresponding to the first transmission scheme, the codebook subset corresponding to the first transmission scheme, the precoding matrix indicator (TPMI) corresponding to the first transmission scheme, the transmission rank indicator (TRI) corresponding to the first transmission scheme, and the maximum number of ports of the PTRS corresponding to the first transmission scheme; for another example, the first device 101 can determine the first width based on the local configuration; for another example, the first device 101 can determine the first width based on the previous interaction content with the second device 102.

[0211] The above-mentioned first device 101 can determine the second width in a variety of ways, which is not limited in this disclosure. For example, the first device 101 can determine the second width through a second parameter. The second parameter can be a related parameter under the second transmission scheme, and the second parameter can be used to configure the transmission method of the signal in the second transmission scheme, or the second parameter can be used to indicate the configuration parameters related to transmission in the second transmission scheme; for example, the second parameter can be the maximum number of layers corresponding to the second transmission scheme, the codebook subset corresponding to the second transmission scheme, the precoding matrix indicator (TPMI) corresponding to the second transmission scheme, the transmission rank indicator (TRI) corresponding to the second transmission scheme, and the maximum number of ports of the PTRS corresponding to the second transmission scheme; for another example, the first device 101 can determine the second width based on the local configuration; for another example, the first device 101 can determine the second width based on the previous interaction content with the second device 102.

[0212] Optionally, when the first device 101 determines the first width based on TRI, the first device 101 preferentially determines the second width based on TRI.

[0213] Optionally, in some embodiments, the maximum number of layers corresponding to the first transmission scheme, the maximum number of layers corresponding to the second transmission scheme, the maximum number of ports of the codebook subset, TPMI, TRI, and PTRS may be predetermined by the first device 101.

[0214] Optionally, in some embodiments, the above-mentioned "first width required for the first indication field of the first signaling in the first transmission scheme" can be understood as: the bit width required for the first indication field (for example, the required minimum bit width) on the premise that the association relationship between the ports in the first transmission scheme can be clearly indicated; similarly, the above-mentioned "second width required for the first indication field of the first signaling in the second transmission scheme" can be understood as: the bit width required for the first indication field (for example, the required minimum bit width) on the premise that the association relationship between the ports in the second transmission scheme can be clearly indicated.

[0215] Step 2102: The first width is different from the second width, and the first device 101 performs a first operation.

[0216] Optionally, in some embodiments, the difference between the first width and the second width may include any of the following:

[0217] The first indication field exists in the first signaling of the first transmission scheme and the second transmission scheme, and the first width is different from the second width;

[0218] One of the first signaling in the first transmission scheme and the first signaling in the second transmission scheme does not include the first indication field.

[0219] In which, when the first signaling in the first transmission scheme does not include the first indication field, the first width is 0; when the first signaling in the second transmission scheme does not include the first indication field, the second width is 0.

[0220] Optionally, in some embodiments, the first operation may be used to make the width of the first signaling to be sent in the first transmission scheme the same as the width of the first signaling to be sent in the second transmission scheme.

[0221] Optionally, the above-mentioned "first signaling to be sent in the first transmission scheme" can be understood as: the first signaling that the first device 101 needs to send to the second device 102 in the first transmission scheme, or, it can be understood as: in the first transmission scheme, the first signaling sent by the first device 101 and received by the second device 102. The above-mentioned "first signaling to be sent in the second transmission scheme" can be understood as: the first signaling that the first device 101 needs to send to the second device 102 in the second transmission scheme, or, it can be understood as: in the second transmission scheme, the first signaling sent by the first device 101 and received by the second device 102.

[0222] Optionally, in some embodiments, the performing of the first operation may include the following steps:

[0223] Step 2102a1: Determine a first target value.

[0224] Optionally, the first target value is the maximum value of the first width and the second width, or the first target value is greater than any value of the first width and the second width. Optionally, when the first target value is greater than any value of the first width and the second width, the first target value may be calculated based on a first preset rule, which may be agreed upon by a protocol, or may be configured from the first device 101 to the second device 102. The first preset rule may, for example, be: adding a first fixed value to the maximum value of the first width and the second width to obtain the first target value.

[0225] Optionally, the first target value may be a preconfigured value, and the first target value may be greater than the first width and the second width. For example, the first target value may be preconfigured to allow selections of 8, 16, 64, 128, and so on. If the first width is 6 and the second width is 18, then the first target value may be 64, 128, and so on. The first target value may be the smallest preconfigured value that is greater than the first width and the second width. For example, the first target value may be 64 instead of 128.

[0226] Step 2102a2: Perform a zero-padding operation on the first indication field so that the third width and the fourth width are both the first target value.

[0227] Optionally, in some embodiments, the third width is the bit width of the first indication field in the first signaling to be sent in the first transmission scheme after the zero-padding operation, and the fourth width is the bit width of the first indication field in the first signaling to be sent in the second transmission scheme after the zero-padding operation.

[0228] Optionally, the above-mentioned zero-padding operation can be performed on the first indication field of the first signaling in the first transmission scheme. For example, when the first width is less than the second width and the first target value is the second width, the zero-padding operation can be performed on the first indication field of the first signaling in the first transmission scheme.

[0229] Alternatively, the above-mentioned zero-padding operation can be performed on the first indication field of the first signaling in the second transmission scheme. For example, when the first width is greater than the second width and the first target value is the first width, the zero-padding operation can be performed on the first indication field of the first signaling in the second transmission scheme.

[0230] Alternatively, the above-mentioned zero-padding operation can be performed on the first indication field of the first signaling in the first transmission scheme, and the first indication field of the first signaling in the second transmission scheme. For example, when the first target value is greater than the values ​​of the first width and the second width, the zero-padding operation can be performed on the first indication field of the first signaling in the first transmission scheme, and the zero-padding operation can be performed on the first indication field of the first signaling in the second transmission scheme.

[0231] Optionally, step 2102a2 is executed to make the width of the first indicator field of the first signaling the same as the width of the first indicator field of the first signaling to be sent in the second transmission scheme, both of which are first target values. Since the widths of other indicator fields in the first signaling except the first indicator field are the same in different transmission schemes, when the width of the first indicator field of the first signaling in the first transmission scheme is made the same as the width of the first indicator field of the first signaling to be sent in the second transmission scheme, it also means that the width of the first signaling in the first transmission scheme is made the same as the width of the first signaling to be sent in the second transmission scheme.

[0232] Optionally, in some other embodiments, the above-mentioned performing of the first operation may include the following steps:

[0233] Step 2102b1: Determine the fifth width and the sixth width.

[0234] Optionally, the fifth width is the bit width corresponding to the first signaling when the first indication field is the first width, and the sixth width is the bit width corresponding to the first signaling when the first indication field is the second width.

[0235] Optionally, the above-mentioned method for determining the fifth width may include: adding the first width to the bit width of other indication fields in the first signaling except the first indication field to obtain the fifth width; the above-mentioned method for determining the sixth width may include: adding the second width to the bit width of other indication fields in the first signaling except the first indication field to obtain the sixth width.

[0236] Optionally, the bit widths of other indication fields except the first indication field in the first signaling are known in advance by the first device 101 and the second device 102 .

[0237] Step 2102b2: Determine the second target value.

[0238] Optionally, the second target value is the maximum value between the fifth width and the sixth width, or the second target value is greater than any value between the fifth width and the sixth width. Optionally, when the second target value is greater than any value between the fifth width and the sixth width, the second target value may be calculated based on a second preset rule, which may be agreed upon by a protocol or configured by the first device 101 to the second device 102. The second preset rule may, for example, be: adding a second fixed value to the maximum value between the fifth width and the sixth width to obtain the second target value.

[0239] Step 2102b3: Perform a zero padding operation on the first signaling so that the seventh width and the eighth width are both the second target value.

[0356] The following is an exemplary introduction to the above method.

[0357] The present disclosure discloses a method for determining the number of DCI bits in the PTRS-DMRS association indication field during transmission in STxMP transmission. The optional implementation scheme is as follows:

[0358] Determine the number of bits in the indicator field and the zero padding method

[0359] Configure STxMP transmission as one of the {SDM, SFN} modes according to RRC signaling, thereby determining the specific STxMP transmission scheme;

[0360] The maximum number of bits M and N corresponding to the DCI indication field under the STRP and STxMP transmission schemes are determined according to the different maximum number of layers (maxRank, maxRank') configured by RRC, the maximum number of PTRS ports, and the codebook subset parameters;

[0361] Further determine the alignment mode of the indicator field actually used for DCI transmission and the actual number of bits of the DCI indicator field:

[0362] Case 1: When there are PTRS-DMRS association indication fields in both STRP and SDM / SFN

[0363] Alt.1: The number of bits in the PTRS-DMRS indicator field corresponding to the same group (maxRank, maxRank') is determined by the number of bits in the larger indicator field of STRP and SDM / SFN.

[0364] Alt.2: Keep the number of bits in the indicator field unchanged and align the bits to the overall DCI size with zero padding.

[0365] Case 2: For STRP or SDM / SFN, whether there is a PTRS-DMRS association indication field

[0366] Alt.1: Keep the number of bits in the DCI indicator field unchanged, and finally align to the overall DCI size with zero padding. For example, for maxRank' = 1, the corresponding bit in STXMP transmission can be 0, and for maxRank = 2 in STRP transmission, the corresponding number of bits in the indicator field can be 1 (FC) or 2 (PC).

[0367] The above applies to DCI format 0_1 ​​and DCI format 0_2 respectively;
