[0050] The terminal (device) involved in the embodiments of the present application can refer to a device that provides voice and / or data connectivity for a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in the 5G system, the terminal device can be called a user equipment (User Equipment, UE).

[0051] The network device related to the embodiments of the present application can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between wireless terminal devices and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present application can be a network device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), and can also be a network device (Nodeb) in Wide-Band Code Division Multiple Access (WCDMA), and can also be an evolved network device (Evolutional Node B, eNB or E-Nodeb) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (Next Generation System), and can also be a Home Evolved Node B (HeNB), a relay node (Relay Node), a femto base station (FEMTO), a pico base station (PICO), etc., which are not limited in the embodiments of the present application. In some network structures, the network device can include a centralized unit (Centralized Unit, CU) node and a distributed unit (Distributed Unit, DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0052] The network device and the terminal device can each use one or more antennas for multi-input multi-output (MIMO) transmission, which can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the shape and number of root antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or Massive-MIMO, or can be diversity transmission, precoding transmission or beamforming transmission, etc.

[0053] As shown in Figure 1 The embodiments of the present application disclose a parameter configuration method, which can be applied to a network device. The method can include the following steps:

[0054] In step 101, a terminal is configured with parameter information, wherein the parameter information includes at least one of a window size of a time window and a demodulation reference signal (DMRS) bundling size.

[0055] The window size indicates a first number of time domain resource units included in the time window, and the DMRS bundling size indicates a second number of time domain resource units of the DMRS bundling.

[0056] The window size is greater than or equal to the DMRS bundling size.

[0057] The time domain resource unit can be a slot, a sub-slot, a repetition, etc., and the time window (Time Window or Time Domain Window) is a preset number of time domain resource units. Optionally, the parameter information is used for joint channel estimation, and the network device configures the parameter information for the UE in a manner of implicit configuration or explicit configuration. The explicit configuration is configured by a signaling message, and the implicit configuration is bound to a transmission resource.

[0058] A demodulation reference signal (DMRS) bundling size indicates a second time domain resource unit number of the DMRS bundling, i.e., a time domain resource unit number occupied by the DMRS transmission. Specifically, the DMRS is usually used for physical downlink shared channel (PDSCH) demodulation, and is shared with a PUSCH or a physical uplink control channel (PUCCH) in a resource area. In 5G NR, the DMRS is used for related demodulation of most channels, including a cell-specific broadcast channel and a UE-specific service channel, etc. At the receiving end, by analyzing the DMRS, channel estimation of a physical layer channel is realized, so as to obtain the characteristics of the physical channel.

[0059] The window size and the DMRS bundling size can be independently configured, and the window size is greater than or equal to the DMRS bundling size, so as to ensure that the power consistency and the phase continuity of the joint channel estimation transmission can be met. The parameter information includes at least one of a window size of a time window and a demodulation reference signal (DMRS) bundling size. Specifically, if the window size is equal to the DMRS bundling size, the network device configures or agrees on one of the window size or the DMRS bundling size for the UE through a protocol; if the window size is greater than the DMRS bundling size, the network device configures the window size and the DMRS bundling size for the UE respectively; or a certain mapping relationship between the two is agreed upon through a standard, and the size of the other is implicitly derived according to a rule based on one of the sizes.

[0060] As a first example, as shown in FIG. 1, Figure 2 As shown in FIG. 1, Figure 2 A schematic diagram of a time window and a DMRS bundling size is shown, where the window size is 4 (4 time domain resource units) and the DMRS bundling size is 2.

[0061] In the embodiment of the application, by configuring the terminal with parameter information including at least one of a window size of a time window and a DMRS bundling size, the UE ensures power consistency and phase continuity within the same time window, and avoids situations such as the phase continuity of joint channel estimation being destroyed.

[0062] As an optional implementation, the embodiment of the application can be applied to the following scenarios:

[0063] Scenario 1: back-to-back PUSCH transmission in the same time slot;

[0064] Scenario 2, non-back-to-back PUSCH transmission in the same time slot;

[0065] Scenario 3, back-to-back PUSCH transmission in consecutive time slots;

[0066] Scenario 4, non-back-to-back PUSCH transmission in consecutive time slots;

[0067] Scenario 5, PUSCH transmission in non-consecutive time slots, and the like.

[0068] Here, the back-to-back transmission means two consecutive PUSCH transmissions.

[0069] It can be understood that the embodiments of the present application can also be applied to other scenarios, which are not limited here.

[0070] In an optional embodiment, after the terminal is configured with the parameter information, the method comprises at least one of the following:

[0071] Method one, sending the parameter information to the terminal through a preset signaling message;

[0072] and

[0073] Method two, setting the parameter information in correspondence with a preset transmission resource and / or resource parameters of the preset transmission resource.

[0074] In the first mode, the display configuration mode is adopted, and the parameter information is carried in the preset signaling message. For example, when the RRC signaling message is sent, the window size and the DMRS bundling size are indicated to the UE, or when the MAC-CE signaling message and the DCI signaling message are sent, the window size and the DMRS bundling size are indicated to the UE. In this way, the UE obtains the parameter information from the signaling message when receiving the signaling message. In the second mode, the implicit configuration mode is adopted, and the correspondence between the parameter information and the preset transmission resource and / or resource parameter is preset. For example, the network device preconfigures the correspondence: for the PUSCH resource 1, the corresponding window size is 4, and the DMRS bundling size is 2; for the PUSCH resource 2, the corresponding window size is 6, and the DMRS bundling size is 4. Then, the UE determines the window size as 4 and the DMRS bundling size as 2 when transmitting the PUSCH resource 1 according to the correspondence, and determines the window size as 6 and the DMRS bundling size as 4 when transmitting the PUSCH resource 2 according to the correspondence. In addition, the resource parameter configuration can also be used. For example, for the transmission resource with the repetition of 16, the time window can be 1 / 4 of the repetition number, for example, the repetition number is 16, and the time window can be 4. Alternatively, according to the frequency hopping interval, the corresponding time window can be equal to the frequency hopping interval by default. According to the TDD frame structure, for the continuous uplink time slots that are not more than N time slots, a time window is used by default.

[0075] In an optional embodiment, the preset signaling message includes at least one of the following:

[0076] The RRC signaling message, the MAC-CE signaling message, and the DCI signaling message.

[0077] The network device can send the parameter information to the UE through the preset signaling message (high-layer signaling or physical-layer signaling), such as the RRC signaling message, the MAC-CE signaling message, and the DCI signaling message.

[0078] In an optional embodiment, the parameter information is sent to the terminal through the preset signaling message, including:

[0079] The parameter information is carried in a target indication field in a preset signaling message, and the preset signaling message is sent to the terminal; wherein the target indication field includes at least one of a preset indication field or a newly added indication field.

[0080] The preset indication field is that the parameter information is carried in a preset signaling message by multiplexing an existing indication field, for example, multiplexing a PRI field, multiplexing a power control field, etc.; the newly added indication field is that the parameter information is carried in a preset signaling message by adding a new indication field, for example, adding a 1-bit data indication parameter information in an RRC message.

[0081] In an optional embodiment, the preset transmission resource includes at least one of a physical uplink control channel (PUSCH) resource and a physical uplink shared channel (PUCCH) resource. Taking the PUSCH resource as an example, the network device pre-configures the parameter information corresponding to the PUSCH resource, so that the UE transmits according to the pre-configured parameter information when transmitting the PUSCH resource; for example, for PUSCH resource 1, the corresponding window size is 4, and the DMRS binding size is 2; for PUSCH resource 2, the corresponding window size is 6, and the DMRS binding size is 4.

[0082] In an optional embodiment, the resource parameters of the preset transmission resource include at least one of a repetition parameter, a time domain frequency hopping interval, and an uplink and downlink slot structure configuration; for a data packet, the transmission is repeated on a plurality of continuous transmission resources, so that the receiving end combines the data on the plurality of transmission resources to improve the transmission quality; the time domain frequency hopping interval indicates the frequency hopping interval when the resource is transmitted; the network side can also bind the resource parameters of the preset transmission resource with the parameter information.

[0083] In an optional embodiment, the parameter information further includes first indication information.

[0084] The first indication information indicates that if there is an unavailable interval in the time window, and the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is divided into at least two sub-time windows.

[0085] When there is an unavailable interval in the time window, for example, there are unavailable symbols or slots (there are non-continuous slots or symbols) in the time window due to factors such as a slot format indicator (SFI), a cancel indicator (CI), different PUSCH priorities, and the like, for example, in the foregoing scenarios 2 (non-back-to-back PUSCH transmission in the same slot), scenario 4 (non-back-to-back PUSCH transmission on consecutive slots), and scenario 5 (PUSCH transmission on non-continuous slots), the UE can place the power amplifier module (PA) in an energy-saving state, and the PA state switching between non-back-to-back PUSCH transmissions due to the unavailable symbols or slots will introduce random phase rotation, which will destroy the phase continuity of joint channel estimation, and the defined time window also needs to be split or changed accordingly. Therefore, in the embodiment of the present application, the network device carries first indication information in the parameter information, indicating that when there is an unavailable interval in the time window, if the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is split into at least two sub-time windows, that is, the original time window is a nominal time window, and the split sub-time window is an actual time window.

[0086] As a second example, still referring to Figure 2 , if there is an unavailable interval in time window 2, and if the length of the unavailable interval is greater than or equal to a first preset threshold, the existing window is automatically split, time window 1 (nominal window 1) is split into actual window 1 (time window 1) and actual window 2 (time window 2), as shown in Figure 2 , and if the length of the unavailable interval is less than the first preset threshold, the window is not segmented, and for time window 5, although there is an available interval, the original window remains unchanged. Figure 3

[0087] In an optional embodiment, the first indication information further indicates that after the terminal splits the time window into at least two sub-time windows, if the window size of the sub-time window is less than the DMRS bundling size, that is, the configured DMRS bundling size, the DMRS bundling size is adjusted to the window size of the sub-time window. If the window size of the split sub-time window is less than the DMRS bundling size, the DMRS bundling size is adjusted to the window size of the sub-time window, and the DMRS bundling is ensured to meet the power continuity and phase consistency.

[0088] Reference​Figure 3 For the adjusted time window 2, if the window size N is smaller than the DMRS bundling size M, M is adjusted to N; as Figures 2-3 The original time window size is 4, the bundling size is 2, after splitting, the size of the time window 2 as a sub-time window is reduced to 1, and the DMRS bundling size is also reduced to 1, that is, the corresponding DMRS bundling size in the time window 2 is reduced, as shown in the figure, bundling size = 1.

[0089] In an optional embodiment, the first indication information further indicates that if there is no available DMRS symbol in the sub-time window after the terminal adjusts the DMRS bundling size to the window size of the sub-time window, the DMRS is supplemented and transmitted on a preset time domain resource unit in the sub-time window.

[0090] Generally, there is DMRS distributed on each time slot or each repetition transmission. Due to joint channel estimation, the DMRS density may be reduced, and DMRS transmission is omitted on part of the repetitions or part of the time slots. At this time, for the existing time window and DMRS bundling size, if due to SFI, CI or different priority preemption, there are unavailable symbols or time slots, the unavailable symbols or time slots occur at the original DMRS symbol position or in the time slot containing the DMRS, resulting in that there is no available DMRS symbol in the split sub-time window. At this time, the DMRS needs to be supplemented, and the DMRS is supplemented and transmitted on a preset time domain resource unit in the sub-time window.

[0091] As a third example, in combination with Figure 4 In the adjusted time window 2, there is no available DMRS, so the DMRS needs to be supplemented and transmitted, as shown by the time slot for supplementing and transmitting the DMRS in the figure; and in the time window 5, the unavailable interval does not affect the original available DMRS, so the DMRS does not need to be supplemented and transmitted.

[0092] In an optional embodiment, the preset time domain resource unit includes a first time domain resource unit or a second time domain resource unit;

[0093] The first time domain resource unit includes a preset symbol position of the transmitted target DMRS; the preset symbol position is, for example, a starting position, an ending position, a middle position, etc. within the DMRS bundling size range;

[0094] The second time domain resource unit includes a position after a symbol offset N symbol position of the transmitted target DMRS; wherein M and N are positive integers, that is, the network device configures the offset position of the DMRS for supplementing and transmitting; for example, if M = 0 and N = 5, the DMRS is inserted at the 5th position of the 0th symbol.

[0095] In an optional embodiment, the configuration information of the preset time domain resource unit is sent to the terminal through at least one of the following: an RRC signaling message, a MAC-CE signaling message, and a DCI signaling message.

[0096] In the embodiments of the present application, by configuring the terminal with parameter information including at least one of a window size of a time window and a DMRS bundling size, the UE is ensured to have consistent power and continuous phase within the same time window, and the occurrence of situations such as the phase continuity of joint channel estimation being destroyed is avoided.

[0097] Referring to Figure 5 The embodiments of the present application also disclose a parameter determination method, which can be applied to a terminal, and the method comprises the following steps:

[0098] Step 501: determining parameter information configured by a network device;

[0099] The parameter information includes at least one of a window size of a time window and a demodulation reference signal (DMRS) bundling size.

[0100] The window size indicates a first time domain resource unit number included in the time window, and the DMRS bundling size indicates a second time domain resource unit number of the DMRS bundling.

[0101] The window size is greater than or equal to the DMRS bundling size.

[0102] The time domain resource unit can be a slot, a sub-slot, a repetition, etc., and the time window (Time Window or Time Domain Window) is a preset number of time domain resource units. Optionally, the parameter information is used for joint channel estimation, and the network device configures the parameter information for the UE in a manner of implicit configuration or explicit configuration, for example, the explicit configuration is configured through a signaling message, and the implicit configuration is bound with a transmission resource. Accordingly, the UE can obtain the parameter information through the configuration manner of the network device.

[0103] The Demodulation Reference Signal (DMRS) binding size indicates the number of second time-domain resource units bound to the DMRS, i.e., the number of time-domain resource units occupied by the transmitted DMRS. Specifically, the DMRS is typically used for demodulation of the Physical Downlink Shared channel (PDSCH) and shares a resource area with the PUSCH or Physical Uplink Control Channel (PUCCH). In 5G NR, the DMRS is used for correlation demodulation of most channels, including cell-specific broadcast channels and UE-specific service channels. At the receiving end, by analyzing the DMRS, channel estimation of the physical layer channels is achieved, thereby obtaining the characteristics of the physical channels.

[0104] The window size and DMRS binding size can be configured independently, and the window size is greater than or equal to the DMRS binding size, thereby ensuring that the power consistency and phase continuity of the joint channel estimation transmission can be met. The parameter information includes at least one of the time window size and the demodulation reference signal DMRS binding size; specifically, if the window size is equal to the DMRS binding size, the network device can configure one of the window size or the DMRS binding size for the UE, or agree on it through a protocol; if the window size is greater than the DMRS binding size, the network device can configure the window size and the DMRS binding size for the UE separately; or agree on the mapping relationship between the two through a standard, and derive the size of the other size based on the mapping relationship of one size.

[0105] As a fourth example, such as Figure 2 As shown, Figure 2 A schematic diagram of the time window and DMRS binding size is shown, where the window size is 4 (4 time domain resource units) and the DMRS binding size is 2, with different fill patterns representing one DMRS.

[0106] In this embodiment of the application, by determining the parameter information configured by the network device, the parameter information is subsequently transmitted according to the parameter information, including at least one of the window size of the time window and the DMRS binding size, so that the UE can ensure power consistency and phase continuity within the same time window, and avoid the occurrence of situations such as the phase continuity of the joint channel estimation being destroyed.

[0107] In an optional embodiment, the parameter information for determining the network device configuration includes at least one of the following:

[0108] Method 3: Receive the parameter information sent by the network device via a preset signaling message;

[0109] and

[0110] In a fourth mode, the parameter information corresponding to the preset transmission resource and / or the resource parameter of the preset transmission resource is determined.

[0111] In the third mode, a display configuration mode is adopted, and the UE receives the parameter information from a preset signaling message. For example, when a RRC signaling message is sent, the window size and the DMRS bundling size are indicated to the UE, or when a MAC-CE signaling message and a DCI signaling message are sent, the window size and the DMRS bundling size are indicated to the UE, so that the UE obtains the parameter information from the signaling message. In the fourth mode, an implicit configuration mode is adopted, and the UE determines the parameter information according to the correspondence between the preset transmission resource and / or the resource parameter and the parameter information. For example, the network device pre-configures a correspondence: for PUSCH resource 1, the corresponding window size is 4, and the DMRS bundling size is 2; for PUSCH resource 2, the corresponding window size is 6, and the DMRS bundling size is 4; then the UE determines the window size to be 4 and the DMRS bundling size to be 2 when transmitting the PUSCH resource 1 according to the correspondence, and determines the window size to be 6 and the DMRS bundling size to be 4 when transmitting the PUSCH resource 2 according to the correspondence. In addition, the resource parameter configuration can also be used, for example, for a transmission resource with a Repetition of 16, the time window can be 1 / 4 of the Repetition, for example, the Repetition is 16, and the time window can be 4; or according to the frequency hopping interval, the corresponding time window can be equal to the frequency hopping interval by default; according to the TDD frame structure configuration, for a continuous uplink time slot of no more than N consecutive time slots, a time window is defaulted.

[0112] In an optional embodiment, the preset signaling message includes at least one of the following:

[0113] a radio resource control (RRC) signaling message, a medium access control (MAC) control element (CE) signaling message, and a downlink control information (DCI) signaling message.

[0114] In the third mode, a display configuration mode is adopted, and the UE receives the parameter information from a preset signaling message. For example, when a RRC signaling message is sent, the window size and the DMRS bundling size are indicated to the UE, or when a MAC-CE signaling message and a DCI signaling message are sent, the window size and the DMRS bundling size are indicated to the UE, so that the UE obtains the parameter information from the signaling message. In the fourth mode, an implicit configuration mode is adopted, and the UE determines the parameter information according to the correspondence between the preset transmission resource and / or the resource parameter and the parameter information. For example, the network device pre-configures a correspondence: for PUSCH resource 1, the corresponding window size is 4, and the DMRS bundling size is 2; for PUSCH resource 2, the corresponding window size is 6, and the DMRS bundling size is 4; then the UE determines the window size to be 4 and the DMRS bundling size to be 2 when transmitting the PUSCH resource 1 according to the correspondence, and determines the window size to be 6 and the DMRS bundling size to be 4 when transmitting the PUSCH resource 2 according to the correspondence. In addition, the resource parameter configuration can also be used, for example, for a transmission resource with a Repetition of 16, the time window can be 1 / 4 of the Repetition, for example, the Repetition is 16, and the time window can be 4; or according to the frequency hopping interval, the corresponding time window can be equal to the frequency hopping interval by default; according to the TDD frame structure configuration, for a continuous uplink time slot of no more than N consecutive time slots, a time window is defaulted.

[0115] In an optional embodiment, the receiving the parameter information sent by the network device through the preset signaling message comprises:

[0116] obtaining the parameter information carried in a target indication field in the preset signaling message; wherein the target indication field comprises at least one of a preset indication field or a newly added indication field; wherein the preset indication field is to multiplex an existing indication field in the preset signaling message to carry the parameter information, for example, multiplexing a PRI field, multiplexing a power control field, etc.; the newly added indication field is to add a new indication field in the preset signaling message to carry the parameter information, for example, adding a 1-bit data indication parameter information in an RRC message.

[0117] In an optional embodiment, the preset transmission resource comprises at least one of a physical uplink control channel (PUSCH) resource and a physical uplink shared channel (PUCCH) resource. Taking the PUSCH resource as an example, the network device pre-configures the parameter information corresponding to the PUSCH resource, so that the UE transmits according to the pre-configured parameter information when transmitting the PUSCH resource; for example, for the PUSCH resource 1, the window size corresponding thereto is 4, and the DMRS binding size is 2; for the PUSCH resource 2, the window size corresponding thereto is 6, and the DMRS binding size is 4.

[0118] In an optional embodiment, the preset transmission resource comprises at least one of a resource parameter repetition parameter, a time domain frequency hopping interval, and an uplink and downlink slot structure configuration.

[0119] In an optional embodiment, after determining the parameter information configured by the network device, the method comprises:

[0120] receiving first indication information, if there is an unavailable interval in the time window, and the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is divided into at least two sub-time windows.

[0121] When there is an unavailable interval in the time window, for example, there is an unavailable symbol or slot in the time window due to SFI, CI, PUSCH priority difference, etc., for example, in the aforementioned scenarios 2 (non-back-to-back PUSCH transmission in the same slot), scenario 4 (non-back-to-back PUSCH transmission on consecutive slots), and scenario 5 (PUSCH transmission on non-consecutive slots), etc., the UE can put its power amplifier module (PA) into an energy-saving state, and due to the unavailable symbol or slot, the PA state switching between non-back-to-back PUSCH transmissions will introduce random phase rotation, which will destroy the phase continuity of joint channel estimation, and at this time, the defined time window also needs to be split or changed. Therefore, in the embodiments of the present application, when the UE receives the first indication information, if there is an unavailable interval in the time window, and the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is divided into at least two sub-time windows, that is, the original time window is a nominal time window, and the segmented sub-time window is an actual time window.

[0122] As a fifth example, still referring to Figure 2 , if there is an unavailable interval in the time window 2, if the length of the unavailable interval is greater than or equal to a first preset threshold, the existing window is automatically segmented, and the time window 1 (nominal window 1) is segmented into an actual window 1 (time window 1) and an actual window 2 (time window 2) corresponding to the original window size of 4 slots in Figure 2 , as shown in Figure 3 ; if the length of the unavailable interval is less than the first preset threshold, the window is not segmented, and for the time window 5, although there is an available interval, the original window remains unchanged.

[0123] In an optional embodiment, after the time window is divided into at least two sub-time windows, the method further comprises:

[0124] If the window size of the sub-time window is less than the DMRS binding size, the DMRS binding size is adjusted to the window size of the sub-time window, that is, if the window size of the segmented sub-time window is less than the DMRS binding size, the DMRS binding size is adjusted and reduced to the window size of the sub-time window, to ensure that the DMRS binding can meet the power continuity and phase consistency.

[0125] Referring to Figure 3 , for the adjusted time window 2, if the window size N is less than the DMRS binding size M, M is adjusted to N; as shown in Figures 2-3, originally the time window size is 4, the bundling size is 2, after splitting, the size of the time window 2 as a sub time window is reduced to 1, then the DMRS bundling size is also adjusted to 1, i.e. the corresponding DMRS bundling size in the time window 2 is reduced, as shown in the figure, the bundling size = 1.

[0126] In an optional embodiment, after the time window is split into at least two sub time windows, the method further comprises:

[0127] If there is no available DMRS symbol in the sub time window, the target DMRS is additionally transmitted in a preset time domain resource unit.

[0128] Generally, there is DMRS distributed in each time slot or each repetition transmission, and due to joint channel estimation, the DMRS density can be reduced, and DMRS transmission is omitted in part of the repetitions or part of the time slots. At this time, for the existing time window and DMRS bundling size, if due to SFI, CI or different priority preemption, there are unavailable symbols or time slots, the unavailable symbols or time slots occur in the original DMRS symbol position or in the time slot containing the DMRS, resulting in that there is no available DMRS symbol in the split sub time window, at this time, the DMRS needs to be supplemented, and the DMRS is additionally transmitted in a preset time domain resource unit in the sub time window.

[0129] As a sixth example, in combination with Figure 4 In the adjusted time window 2, there is no available DMRS, so the DMRS needs to be additionally transmitted, as shown by the time slot for additionally transmitting the DMRS in the figure; and in the time window 5, the unavailable interval does not affect the original available DMRS, so the DMRS does not need to be additionally transmitted.

[0130] In an optional embodiment, the preset time domain resource unit includes a first time domain resource unit or a second time domain resource unit.

[0131] The first time domain resource unit includes a preset symbol position of the transmitted target DMRS; the preset symbol position is, for example, a starting position, an ending position, a middle position, etc. within the DMRS bundling size range.

[0132] The second time domain resource unit includes a position after a symbol offset N symbol position of the transmitted target DMRS; wherein M and N are positive integers, i.e. the network device configures the offset position of the DMRS for additional transmission; for example, if M = 0 and N = 5, the DMRS is inserted at the 5th position of the 0th symbol.

[0133] In an optional embodiment, the configuration information of the preset time domain resource unit is preset or obtained from at least one of the following signaling messages sent by the network device: an RRC signaling message, a MAC-CE signaling message, and a DCI signaling message.

[0134] In the embodiments of the present application, by determining the parameter information configured by the network device, at least one of the window size of the time window and the DMRS bundling size is transmitted according to the parameter information, so that the UE ensures consistent power and continuous phase in the same time window, and avoids the occurrence of situations such as the destruction of the phase continuity of joint channel estimation.

[0135] The embodiments of the present application also provide an information indication method. Optionally, the method can be applied to a network device, and the method comprises the following steps:

[0136] sending first indication information to a terminal; wherein the first indication information is used to indicate that, when there is an unavailable interval in a time window, if the length of the unavailable interval is greater than a first preset threshold, the time window is divided into at least two sub-time windows.

[0137] When there is an unavailable interval in a time window, for example, due to factors such as a slot format indicator (SFI), a cancel indicator (CI), different PUSCH priorities, etc., there are unavailable symbols or slots (there are non-continuous slots or symbols) in the time window, for example, in the aforementioned scenarios 2 (non-back-to-back PUSCH transmission in the same slot), scenario 4 (non-back-to-back PUSCH transmission on continuous slots), and scenario 5 (PUSCH transmission on non-continuous slots), etc., the UE can put the power amplifier module (PA) into an energy-saving state. As a result of the unavailable symbols or slots, the PA state switching between non-back-to-back PUSCH transmissions will introduce random phase rotation, which will destroy the phase continuity of joint channel estimation. At this time, the time window that has been defined also needs to be split or changed. Therefore, in the embodiments of the present application, the network device carries first indication information in the parameter information, indicating that, when there is an unavailable interval in the time window, if the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is divided into at least two sub-time windows, that is, the original time window is a nominal time window (nominal), and the sub-time window after division is an actual time window (actual).

[0138] As a seventh example, still referring to Figure 2, if an unavailable interval occurs in the time window 2, if the length of the unavailable interval is greater than or equal to a first preset threshold, the existing window is automatically segmented, the time window 1 (nominal window 1) is segmented into an actual window 1 (time window 1) and an actual window 2 (time window 2), as shown in Figure 2 , and if the length of the unavailable interval is less than the first preset threshold, the window is not segmented, and for the time window 5, although there is an available interval, the original window remains unchanged. Figure 3

[0139] In an optional embodiment, if the length of the unavailable interval is less than the first preset threshold, the terminal is instructed not to perform adjustment processing on the time window; accordingly, when the length of the unavailable interval is equal to the first preset threshold, the first indication information can be used to instruct the terminal to perform adjustment processing on the time window, or to instruct the terminal not to perform adjustment processing on the time window.

[0140] In an optional embodiment, the first indication information further instructs the terminal, after segmenting the time window into at least two sub-time windows, if the window size of the sub-time window is less than the DMRS bundling size, i.e., the configured DMRS bundling size, to adjust the DMRS bundling size to the window size of the sub-time window.

[0141] That is, if the window size of the segmented sub-time window is less than the DMRS bundling size, the DMRS bundling size is adjusted to the window size of the sub-time window, to ensure that the DMRS bundling can meet the power continuity and phase consistency.

[0142] Referring to Figure 3 , for the adjusted time window 2, if the window size N is less than the DMRS bundling size M, M is adjusted to N; as shown in Figures 2-3 , the original time window size is 4, the bundling size is 2, after segmentation, the size of the time window 2 as a sub-time window is reduced to 1, and the DMRS bundling size is also adjusted to 1, that is, the DMRS bundling size corresponding to the time window 2 is reduced, as shown in the figure, bundling size = 1.

[0143] In an optional embodiment, the first indication information further instructs the terminal, after adjusting the DMRS bundling size to the window size of the sub-time window, if there is no available DMRS symbol in the sub-time window, to supplement the transmission of the DMRS on the preset time domain resource unit in the sub-time window.

[0144] ​Generally, there are DMRSs distributed on each time slot or each repetition transmission. Due to joint channel estimation, the DMRS density can be reduced, and the DMRS transmission can be omitted on part of the repetitions or part of the time slots. In this case, for the existing time window and DMRS binding size, if there are unavailable symbols or time slots due to SFI, CI or preemption of different priorities, the unavailable symbols or time slots occur at the original DMRS symbol position or in the time slot containing the DMRS, resulting in that there is no available DMRS symbol in the split sub-time window. In this case, the DMRS needs to be supplemented, and the DMRS is supplemented and transmitted on the preset time domain resource unit in the sub-time window.

[0145] As an eighth example, in combination with Figure 4 In the adjusted time window 2, there is no available DMRS, and the DMRS needs to be supplemented and transmitted, as shown by the time slot for supplementing and transmitting the DMRS in the figure. In the time window 5, the unavailable interval does not affect the original available DMRS, and the DMRS does not need to be supplemented and transmitted.

[0146] In an optional embodiment, the preset time domain resource unit includes a first time domain resource unit or a second time domain resource unit.

[0147] The first time domain resource unit includes a preset symbol position of the transmitted target DMRS. The preset symbol position is, for example, a starting position, an ending position, a middle position, etc. within the DMRS binding size range.

[0148] The second time domain resource unit includes a position after the Mth symbol offset N symbol position of the transmitted target DMRS. M and N are positive integers, that is, the network device configures the offset position of the DMRS for supplementing and transmitting. For example, if M = 0 and N = 5, the DMRS is inserted at the 5th position of the 0th symbol.

[0149] In an optional embodiment, the configuration information of the preset time domain resource unit is sent to the terminal by at least one of the following: an RRC signaling message, a MAC-CE signaling message, and a DCI signaling message.

[0150] In the embodiments of the present application, by sending first indication information to the terminal, the first indication information is used to indicate that when there is an unavailable interval in the time window, if the length of the unavailable interval is greater than a first preset threshold, the time window is split into at least two sub-time windows to ensure the transmission of the DMRS, so that the UE ensures consistent power and phase continuity in the same time window, and avoids the occurrence of situations such as the phase continuity of joint channel estimation being destroyed.

[0151] The embodiment of the present application further provides an information receiving method. Optionally, the method can be applied to a terminal, and the method comprises the following steps:

[0152] receiving first indication information;

[0153] In response to the first indication information, if there is an unavailable interval in the time window, and the length of the unavailable interval is greater than a first preset threshold, the time window is divided into at least two sub-time windows.

[0154] In the case that there is an unavailable interval in the time window, for example, due to factors such as a slot format indicator (SFI), a cancel indicator (CI), different PUSCH priorities, and the like, an unavailable symbol or time slot (there are non-continuous time slots or symbols) appears in the time window, for example, in the foregoing scenarios 2 (non-back-to-back PUSCH transmission in the same time slot), scenario 4 (non-back-to-back PUSCH transmission on continuous time slots), and scenario 5 (PUSCH transmission on non-continuous time slots), and the like, the UE can place a power amplifier (PA) module in an energy-saving state. As a result of the unavailable symbol or time slot, the PA state switching between non-back-to-back PUSCH transmissions will introduce random phase rotation, which will destroy the phase continuity of joint channel estimation. At this time, the time window that has been defined also needs to be split or changed. Therefore, in the embodiment of the present application, the network device carries first indication information in the parameter information, indicating that if there is an unavailable interval in the time window, and the length of the unavailable interval is greater than or equal to a first preset threshold, the time window is divided into at least two sub-time windows, that is, the original time window is a nominal time window (nominal), and the sub-time window after the division is an actual time window (actual).

[0155] As a ninth example, still referring to Figure 2 , if an unavailable interval appears in the time window 2, and the length of the unavailable interval is greater than or equal to a first preset threshold, the existing window is automatically split, the time window 1 (nominal window 1) is segmented into an actual window 1 (time window 1) and an actual window 2 (time window 2) corresponding to Figure 2 , as shown in Figure 3 , and if the length of the unavailable interval is less than the first preset threshold, the window is not segmented. For the time window 5, although there is an available interval, the original window remains unchanged.

[0156] In an optional embodiment, if the duration of the unavailable interval is less than the first preset threshold, the terminal does not perform adjustment on the time window; accordingly, when the duration of the unavailable interval is equal to the first preset threshold, the terminal performs adjustment on the time window, or the terminal does not perform adjustment on the time window.

[0157] In an optional embodiment, after the time window is divided into at least two sub-time windows, the method further comprises:

[0158] If the window size of the sub-time window is less than the DMRS bundling size, i.e., the configured DMRS bundling size, the DMRS bundling size is adjusted to the window size of the sub-time window.

[0159] That is, if the window size of the divided sub-time window is less than the DMRS bundling size, the DMRS bundling size is adjusted to the window size of the sub-time window, so as to ensure that the DMRS bundling can meet the power continuity and phase consistency.

[0160] Reference Figure 3 For the adjusted time window 2, if the window size N is less than the DMRS bundling size M, M is adjusted to N; for example, Figures 2-3 The original time window size is 4, the bundling size is 2, after division, the size of the time window 2 as a sub-time window is reduced to 1, and the DMRS bundling size is also adjusted to 1, i.e., the DMRS bundling size corresponding to the time window 2 is reduced, as shown in the figure, bundling size = 1.

[0161] In an optional embodiment, after the time window is divided into at least two sub-time windows, the method further comprises:

[0162] If there is no available DMRS symbol in the sub-time window, the DMRS is supplemented and transmitted on the preset time domain resource unit in the sub-time window.

[0163] Generally, there are DMRSs distributed on each time slot or each repetition transmission. Due to joint channel estimation, the DMRS density can be reduced, and the DMRS transmission can be omitted on part of the repetitions or part of the time slots. In this case, for the existing time window and DMRS binding size, if there are unavailable symbols or time slots due to SFI, CI or preemption of different priorities, the unavailable symbols or time slots occur at the original DMRS symbol position or in the time slot containing the DMRS, resulting in that there is no available DMRS symbol in the split sub-time window. In this case, the DMRS needs to be supplemented, and the DMRS is supplemented and transmitted on the preset time domain resource unit in the sub-time window.

[0164] As a tenth example, in combination with Figure 4 In the adjusted time window 2, there is no available DMRS, and the DMRS needs to be supplemented and transmitted, as indicated by the time slot for supplementing and transmitting the DMRS in the figure. In the time window 5, the unavailable interval does not affect the original available DMRS, and the DMRS does not need to be supplemented and transmitted.

[0165] In an optional embodiment, the preset time domain resource unit includes a first time domain resource unit or a second time domain resource unit.

[0166] The first time domain resource unit includes a preset symbol position of the transmitted target DMRS. The preset symbol position is, for example, a starting position, an ending position, a middle position, etc. within the DMRS binding size.

[0167] The second time domain resource unit includes a position after the Mth symbol offset N symbol position of the transmitted target DMRS. M and N are positive integers, that is, the network device configures the offset position of the DMRS for supplementing and transmitting. For example, if M=0 and N=5, the DMRS is inserted at the 5th position of the 0th symbol.

[0168] In an optional embodiment, the configuration information of the preset time domain resource unit is sent to the terminal through at least one of the following: an RRC signaling message, a MAC-CE signaling message and a DCI signaling message.

[0169] In the embodiments of the present application, by receiving and responding to the first indication information, when there is an unavailable interval in the time window, if the length of the unavailable interval is greater than a first preset threshold, the UE splits the time window into at least two sub-time windows to ensure the transmission of the DMRS, so that the UE ensures consistent power and phase continuity in the same time window, and avoids the occurrence of situations such as the phase continuity of joint channel estimation being destroyed.
