[0001] This application is a divisional application of the original Chinese application with application number "202080095011.6" filed on May 14, 2020, wherein the original Chinese application is incorporated by reference into this divisional application. Technical Field

[0002] The present application relates to communication technology, and in particular to an uplink sending method and device. Background Art

[0003] In New Radio (NR), high-frequency band communications are usually used, which can provide high-speed, low-latency data transmission to meet user needs.

[0004] The use of high frequency bands will lead to the problem of limited uplink coverage. In order to solve the problem of limited uplink coverage, the uplink coverage can be enhanced by improving the quality of channel estimation. The quality of channel estimation is usually improved by increasing the density of reference signals (RS). For example, in addition to the basic demodulation reference signals (DMRS) in NR, additional DMRS (additional DMRS) will also be configured.

[0005] However, the above method increases the resource overhead of DMRS and affects the utilization of uplink spectrum. Summary of the invention

[0006] The embodiments of the present application provide an uplink transmission method and device, which can improve the channel estimation quality without adding additional DMRS, thereby saving DMRS resource overhead and improving the utilization of uplink spectrum.

[0007] In a first aspect, an embodiment of the present application provides an uplink transmission method, which may include: receiving a first message sent by an access network device, the first message being used to configure a first uplink resource, and performing uplink transmission on the first uplink resource.

[0008] The first uplink resource includes at least a first part and a second part within a first time period. The phase deviation of the uplink transmission between the first part and the second part is within a first threshold range, and / or the power deviation of the uplink transmission between the first part and the second part is within a second threshold range. The first time period is the time between the start and the end of the first uplink resource within a first time length, or the first time period is the time between the start and the end of the first uplink resource within a first transmission opportunity. The first part and the second part satisfy at least one of the following: the time domain interval between the first part and the second part is greater than 0 time domain resource units, or the first part and the second part are located in different time slots.

[0009] This implementation method controls the phase deviation of the uplink transmission between the first part and the second part within the first threshold range, and / or controls the power deviation of the uplink transmission between the first part and the second part within the second threshold range, so that the access network device can perform filtering for a longer time in the first time period to improve the quality of channel estimation and enhance uplink coverage. This method does not need to add additional DMRS, can save DMRS resource overhead, and improve the utilization rate of uplink spectrum.

[0010] In a possible implementation, the first threshold range is determined by a time domain interval between the first part and the second part, and / or the second threshold range is determined by an interval between time slots where the first part and the second part are located.

[0011] In this implementation, a first threshold range is determined by the time domain interval between the first part and the second part, and then based on the first threshold range, the phase deviation of the uplink transmission between the first part and the second part is controlled to be within the first threshold range, so that the access network device can perform filtering for a longer time in the first time period to improve the quality of channel estimation and enhance uplink coverage.

[0012] The second threshold range is determined by the interval between the time slots where the first part and the second part are located, and then based on the second threshold range, the uplink transmission power deviation between the first part and the second part is controlled to be within the second threshold range, so that the access network device can perform filtering for a longer time within the first time period to improve the quality of channel estimation and enhance uplink coverage.

[0013] In one possible design, the method may also include: receiving first information sent by an access network device, the first information being used to indicate the first time length, or the first information being used to indicate the number M of first transmission opportunities, and the number of first transmission opportunities being used to determine the first transmission opportunity.

[0014] In this implementation, the access network device indicates the first time length or the number M of the first transmission opportunities, so as to control the phase deviation or power deviation of the uplink transmission between the first part and the second part of the corresponding time domain position based on the access network device indication, so that the access network device can perform filtering for a longer time in the first time period to improve the quality of channel estimation and enhance uplink coverage.

[0015] In one possible design, the method may further include: receiving second information sent by the access network device, the second information being used to indicate uplink transmission on the first uplink resource.

[0016] In this implementation, the target channel or target signal is indicated by the access network device so as to control the phase and / or power of the uplink transmission of the target channel or target signal based on the indication of the access network device, thereby allowing the access network device to perform filtering for a longer time within the first time period to improve the quality of channel estimation and enhance uplink coverage.

[0018] In this implementation, the first transmission opportunities of K groups can be determined through the number M of first transmission opportunities and the number P of transmission opportunities of the first uplink resource, and the first time period can be determined based on the first transmission opportunities of the K groups, thereby controlling the phase and / or power of the uplink transmission of the first uplink resource in the first time period, so that the access network device can perform filtering for a longer time in the first time period to improve the quality of channel estimation and enhance uplink coverage.

[0019] In one possible design, the method may also include: determining not to receive downlink information within the first time period.

[0020] In this implementation, for the time division multiplexing mode, the terminal device may not receive downlink information in the first time period, that is, ignore the downlink information.

The core network device and the wireless access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated on the same physical device, or part of the functions of the core network device and part of the functions of the wireless access network device can be integrated on one physical device. The terminal device can be fixed or movable. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Figure 1 The embodiment of the present application does not limit the number of core network devices, wireless access network devices and terminal devices included in the mobile communication system.

[0062] The wireless access network device is an access device that the terminal device uses to access the mobile communication system wirelessly. It can be a base station (NodeB), an evolved base station (eNodeB), a base station in an NR mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device.

[0063] Terminal equipment may also be referred to as terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminal equipment may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0064] The wireless access network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the application scenarios of the wireless access network equipment and terminal equipment.

[0065] The embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is a wireless access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the sending device is a terminal device, and the corresponding receiving device is a wireless access network device. For D2D signal transmission, the sending device is a terminal device, and the corresponding receiving device is also a terminal device. The transmission direction of the signal in the embodiments of the present application is not limited.

[0066] The wireless access network equipment and the terminal equipment, as well as the terminal equipment and the terminal equipment, can communicate through the licensed spectrum, or can communicate through the unlicensed spectrum, or can communicate through the licensed spectrum and the unlicensed spectrum at the same time. The wireless access network equipment and the terminal equipment, as well as the terminal equipment and the terminal equipment, can communicate through the spectrum below 6G, or can communicate through the spectrum above 6G, or can communicate through the spectrum below 6G and the spectrum above 6G at the same time. The embodiments of the present application do not limit the spectrum resources used between the wireless access network equipment and the terminal equipment.

[0067] Figure 2 This is a schematic diagram of some modules involved in uplink transmission in an embodiment of the present application, such as Figure 2 As shown, some modules involved in the uplink transmission may include a baseband integrated circuit (BBIC) 1 and a radio frequency integrated circuit (RFIC) 2. BBIC 1 and RFIC 2 may be two chips, the baseband signal generation module 11 of BBIC 1 is used to generate a normalized baseband signal, and the gain calculation module 12 calculates the gain of the normalized baseband signal, and the gain calculation module 12 sends the gain to RFIC 2, and RFIC 2 calculates the gain through the digital domain (such as Figure 2 The digital domain amplifier 21 shown) and the analog domain (such as Figure 2 The analog domain amplifier 23) shown in the figure has two stages of adjustment to realize the gain sent from the gain calculation module.

[0068] Analog domain gain adjustment or switching will cause phase jumps in uplink transmission. Digital domain gain adjustment will not cause phase jumps in uplink transmission. However, the digital domain gain adjustment module should not be adjusted significantly, because excessive digital domain power will cause saturation of the digital to analog converter (DAC) 22, and too low digital domain power will reduce DAC efficiency. The digital domain power entering the DAC 22 should be relatively stable near a value.

[0069] The power adjustment of the uplink transmission will cause the analog domain gain adjustment, and the switching of the uplink analog domain will cause the switching of the analog domain gain module, thereby causing the phase jump of the uplink transmission.

[0070] In order to solve the problem of limited uplink coverage, the uplink coverage can be enhanced by improving the quality of channel estimation. The embodiment of the present application provides an uplink transmission method, which improves the quality of channel estimation by filtering for a longer time in the time domain, thereby enhancing the uplink coverage. The method does not need to add additional DMRS, can save DMRS resource overhead, and improve the utilization rate of the uplink spectrum. The embodiment of the present application realizes the phase continuity of uplink transmission within a period of time through the implementation methods of the following embodiments, so that longer filtering can be performed in the time domain to improve the quality of channel estimation.

[0071] The phase of the uplink transmission involved in the embodiment of the present application refers to the phase change caused by the analog domain gain adjustment. For example, the phase change caused by the analog domain gain adjustment of the uplink information output by the DAC 22 by the analog domain amplifier 23.

[0072] The uplink information involved in the embodiments of the present application may be physical layer data, physical layer control information, a sounding reference signal (SRS), or random access information, etc. For example, the uplink information may be uplink data carried on a physical uplink shared channel (PUSCH), or uplink information carried on a physical uplink control channel (PUCCH).

[0073] The PUSCH may include a PUSCH based on dynamic scheduling or a PUSCH with a configured grant. For a PUSCH based on dynamic scheduling, the terminal device receives an uplink scheduling, for example, receiving a radio resource control (RRC) signaling, a medium access control-control element (MAC-CE) or a downlink control information (DCI), and the terminal device performs a PUSCH transmission according to the uplink scheduling. For a PUSCH with a configured grant, the PUSCH with a configured grant is periodic, and each period may include a set of transmission occasions, for example, K transmission opportunities. The PUSCH with a configured grant can be divided into a PUSCH with a configured grant type 1 (Type 1) and a PUSCH with a configured grant type 2 (Type 2). For PUSCH configured with grant type 1 (Type 1), the access network device can configure some semi-persistent resources to the terminal device through RRC signaling. If the terminal device has uplink data to send, it can use the semi-persistent resources for uplink transmission. If the terminal device has no uplink data to send, it can not use the semi-persistent resources for uplink transmission. For PUSCH configured with grant type 2 (Type 2), the access network device can configure some semi-persistent resource parameters to the terminal device through RRC signaling, and then use physical layer signaling to configure some semi-persistent resource parameters and activate the semi-persistent resource. It can also use physical layer signaling to deactivate the semi-persistent resource. When the semi-persistent resource is activated, the terminal device can use the semi-persistent resource for uplink transmission. When the semi-persistent resource is not activated or deactivated, the terminal device cannot use the semi-persistent resource for uplink transmission.

[0074] The PUCCH may be periodic, semi-persistent, or dynamically scheduled along with a physical downlink shared channel (PDSCH).

[0075] The SRS can be divided into three modes: periodic, semi-continuous, and non-periodic. For periodic or semi-continuous SRS, a period in slots and a slot offset are configured. The value range of the period is {1,2,4,5,8,10,16,20,32,40,64,80,160,320,640,1280,2560}. For non-periodic SRS, a slot-level offset is configured. The offset is the slot spacing between the triggering DCI and the actual transmission of SRS. The offset can be any value between 0 and 32. When the offset is 0, it means that the triggering DCI and SRS are in the same slot.

[0076] The embodiment of the present application takes the time slot in the NR system as an example for illustration, and its protection scope is not limited to this.

[0077] The transmission occasion of the embodiment of the present application may be one or more repetitions of uplink information. The repeated uplink information here may be repeated physical uplink shared channel (PUSCH), repeated physical uplink control channel (PUCCH), repeated sounding reference signal (SRS) or repeated random access channel (RACH).

[0079] Step 101: An access network device sends a first message to a terminal device.

[0080] The terminal device receives a first message sent by the access network device. The first message is used to configure a first uplink resource.

[0081] The first uplink resource may be a resource that carries any of the above uplink information, for example, a PUSCH resource, a PUCCH resource, a RACH resource, or a resource for sending a sounding reference signal (SRS). The first uplink resource may be dynamically scheduled, semi-persistently, or periodically.

[0082] The dynamic scheduling involved in the embodiments of the present application refers to physical layer signaling scheduling, for example, DCI scheduling. For example, the first uplink resource may be an uplink resource scheduled by DCI. The periodic resources involved in the embodiments of the present application refer to periodic resources configured by RRC signaling that can be used for or used for uplink transmission. For example, the first uplink resource may be a periodic resource configured by RRC signaling that can be used for uplink transmission. The semi-persistent resources involved in the embodiments of the present application refer to periodic resources configured by RRC signaling, which can be used for uplink transmission after being activated by MAC-CE or DCI.

[0084] The access network device performs uplink reception on the first uplink resource.

[0085] The first uplink resource includes at least a first part and a second part in a first time period. The uplink transmission between the first part and the second part can satisfy at least one of the following: the phase deviation of the uplink transmission between the first part and the second part is within a first threshold range, or the power deviation of the uplink transmission between the first part and the second part is within a second threshold range. In other words, the phase deviation of the uplink transmission between the first part and the second part is within the first threshold range, and / or the power deviation of the uplink transmission between the first part and the second part is within the second threshold range.

[0086] The first time period is the time between the start and end of the first uplink resource within the first time length, or the first time period is the time between the start and end of the first uplink resource within the first transmission opportunity. It should be noted that the first time length of the embodiment of the present application may be a time length, for example, 2 time slots, etc. The first time length may be any 2 time slots in the time domain, which has no meaning of the time domain position. Unlike the first time length, the first time period has not only the meaning of the time length, but also the meaning of the time domain position, that is, a time period with a clear position in the time domain. The embodiment of the present application may determine the first time period based on the first time length and the time domain position of the first uplink resource. The first time length may be preset or configured by the access network device. The first transmission opportunity may be a preset number of transmission opportunities (for example, M transmission opportunities) or a first uplink resource transmission (for example, a PUSCH transmission, a PUSCH transmission may include several transmission opportunities), and the first transmission opportunity may be predefined or configured by the access network device.

[0087] For example, see Figure 4A , Figure 4AThis is a schematic diagram of a first time period of an embodiment of the present application. Assuming that the first time length is 2 time slots, the first uplink resources are PUSCH 1, PUSCH 2, PUSCH 3 and PUSCH 4, then the first time period is the time between the start of PUSCH 1 and the end of PUSCH 2 within 2 time slots, and the time between the start of PUSCH 3 and the end of PUSCH 4 within 2 time slots.

[0088] See also Figure 4B , Figure 4B This is a schematic diagram of another first time period of an embodiment of the present application. Assuming that the first uplink resource is PUSCH, one PUSCH transmission includes 6 transmission opportunities. The 6 transmission opportunities are as follows: Figure 4B As shown in FIG. 1 , PUSCH 1, PUSCH 2, PUSCH 3, PUSCH 4, PUSCH 5 and PUSCH 6, the first transmission opportunity is every 3 transmission opportunities of the 6 transmission opportunities. Then, the first time period is the time between the start and the end of the PUSCH in the 3 transmission opportunities. For example, Figure 5 As shown, the first time period is the time between the start of PUSCH 1 and the end of PUSCH 3, and the time between the start of PUSCH 4 and the end of PUSCH 6.

[0089] The first part and the second part satisfy at least one of the following: the time domain interval between the first part and the second part is greater than 0 time domain resource units, or the first part and the second part are located in different time slots. The time domain resource unit can be one Tc, several Tcs, one Ts, several Ts, one symbol, several symbols, or a time slot. c =1 / (Δf max ·N f ), where Δf max =480·10 3 Hz、N f =4096,T s =1 / (Δf ref ·N f,ref ), where Δf ref =15·10 3 Hz,N f,ref = 2048. Tc refers to the basic time unit for NR, and Ts refers to the basic time unit for LTE.

[0090] The time-domain interval between the first part and the second part can be the interval between the end position of the first part in the time domain and the start position of the second part in the time domain. Let N denote the time-domain interval between the first part and the second part. In some embodiments, N>0. For Figure 4A For further illustration, the first part can be PUSCH 1, the second part can be PUSCH 2, and the time-domain interval between the first part and the second part is the interval 1 as Figure 4A shown, and the interval 1 is greater than 0 time-domain resource units.

[0091] It should be noted that the first uplink resource includes at least a first part and a second part within a first time period. Understandably, the first uplink resource may further include other parts within the first time period. For example, a third part, etc. The third part can be a time-domain resource without carrying uplink information or a time-domain resource carrying other uplink information. For Figure 4A For further illustration, in addition to including the first part (PUSCH 1) and the second part (PUSCH 2), the first uplink resource (PUSCH) within the first time period further includes PUCCH, downlink resource (D), and flexible symbol (F), etc. The flexible symbol is generally located between the downlink resource and the uplink resource. The flexible symbol can be configured as a downlink or uplink symbol through physical layer signaling to flexibly support burst services.

[0092] In the embodiments of the present application, the frequency-domain resources of the first part and the second part can be the same to facilitate channel estimation filtering in the time domain between the first part and the second part.

[0093] In some other embodiments, N = 0, that is, there is no time-domain interval between the first part and the second part, and the two are continuous in the time domain. For the first part and the second part without a time-domain interval, the two are located in different time slots, that is, the end position of the first part in the time domain is the last symbol of a time slot, and the start position of the second part in the time domain is the first symbol of the next time slot.

[0094] The phase deviation of the uplink transmission involved in the embodiments of the present application refers to the difference in the phase change between any two uplink transmissions between the first part and the second part. The phase change can be generated by the analog domain gain adjustment as described above. The phase deviation is within a first threshold range.

[0095] For example, the first threshold range can be [-a,a]. Let B denote the phase deviation of the uplink transmission between the first part and the second part. Then, the value of B satisfies: -a < B < a, or, -a ≤ B ≤ a.

[0096] In some embodiments, the first threshold range may be related to the time-domain interval between the first part and the second part. For example, if the first threshold range is [-(N + 1)a, (N + 1)a], then the value of B satisfies: -(N + 1)a < B < (N + 1)a, or, -(N + 1)a ≤ B ≤ (N + 1)a.

[0097] In some embodiments, the first threshold range may be preset or determined by the above-mentioned N, that is, the first threshold range is determined by the time-domain interval between the first part and the second part. For example, the larger the time-domain interval between the first part and the second part, the larger the first threshold range. For example, when the time-domain interval between the first part and the second part is 1 symbol, the first threshold range is [-1, 1]; when the time-domain interval between the first part and the second part is 3 symbols, the first threshold range is [-3, 3].

[0098] The phase deviation of the uplink transmission involved in the embodiments of the present application may also refer to the difference in the phase change between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part. The phase change may be generated by the analog-domain gain adjustment as described above. The phase deviation is within the first threshold range.

[0099] For example, if the first threshold range is [-a, a], and B represents the phase deviation of the uplink transmission between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part, then the value of B satisfies: -a < B < a, or, -a ≤ B ≤ a.

[0100] In some embodiments, the first threshold range may be related to the time-domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part. For example, if the first threshold range is [-(N + 1)a, (N + 1)a], then the value of B satisfies: -(N + 1)a < B < (N + 1)a, or, -(N + 1)a ≤ B ≤ (N + 1)a.

[0101] In some embodiments, the first threshold range may be preset or determined by the above-mentioned N, that is, the first threshold range is determined by the time domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part. For example, the larger the time domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part, the larger the first threshold range. For example, when the time domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part is 1 symbol, the first threshold range is [-1, 1]; when the time domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol in the time domain of the second part is 3 symbols, the first threshold range is [-3, 3].

[0102] Similar to the phase deviation of the uplink transmission, the power deviation of the uplink transmission involved in the embodiments of the present application refers to the difference in the transmission power of any two uplink transmissions between the first part and the second part. The power deviation is within the second threshold range. For example, the second threshold range may be [-c, c]. If D represents the power deviation of the uplink transmission between the first part and the second part, then the value of D satisfies: -c < D < c, or -c ≤ D ≤ c. For example, c may take any value less than 1, such as 1 dB, 0.5 dB, etc.

[0103] In some embodiments, the second threshold range may be related to the time domain interval between the first part and the second part. The second threshold range may be preset or determined by the above-mentioned N, that is, the second threshold range is determined by the time domain interval between the first part and the second part. For example, the larger the time domain interval between the first part and the second part, the larger the second threshold range.

[0104] For the first part internally, that is, for each symbol in the first part, the phase deviation of the uplink transmission of each symbol in the first part is within the first threshold range; for the second part internally, that is, for each symbol in the second part, the phase deviation of the uplink transmission of each symbol in the second part is within the first threshold range, and / or, for the first part internally, the power deviation of the uplink transmission of each symbol in the first part is within the second threshold range, for the second part internally, the power deviation of the uplink transmission of each symbol in the second part is within the second threshold range, and / or, for the first part internally, the uplink transmission power of each symbol in the first part is the same, for the second part internally, the uplink transmission power of each symbol in the second part is the same.

[0105] In some embodiments, the access network device performs uplink reception on the first uplink resource and performs channel estimation. The access network device may perform channel estimation in the following manner: the access network device performs channel estimation for the first part according to the pilot signal of the first part, and performs channel estimation for the second part according to the pilot signal of the second part; or the access network device performs channel estimation for the first part according to the pilot signal of the first part, and performs channel estimation for the second part according to the pilot signal of the first part; or the access network device performs channel estimation for the second part according to the pilot signal of the first part, and performs channel estimation for the second part according to the pilot signal of the second part.

[0106] In this embodiment, a terminal device receives a first message sent by an access network device, and the first message is used to configure a first uplink resource. The terminal device performs uplink transmission on the first uplink resource. The first uplink resource includes at least a first part and a second part in a first time period. The uplink transmission between the first part and the second part can satisfy at least one of the following: the phase deviation of the uplink transmission between the first part and the second part is within a first threshold range, or the power deviation of the uplink transmission between the first part and the second part is within a second threshold range. The terminal device controls the phase deviation of the uplink transmission between the first part and the second part within the first threshold range, and / or controls the power deviation of the uplink transmission between the first part and the second part within the second threshold range, so that the access network device can perform filtering for a longer time in the first time period to improve the quality of channel estimation and enhance uplink coverage. This method does not require the addition of additional DMRS, can save DMRS resource overhead, and improve the utilization of uplink spectrum.

[0107] Figure 5 Flow chart of another uplink sending method of an embodiment of the present application. The method of this embodiment involves a terminal device and an access network device. This embodiment adopts a configuration method of the access network device to the terminal device to configure the first time length or the number M of the first transmission opportunities, the target channel or the target signal, such as Figure 5 As shown, the method of this embodiment may include:

[0108] Step 201: The access network device sends at least one of the first information or the second information to the terminal device.

[0109] The terminal device receives first information sent by the access network device, where the first information is used to indicate a first time length, or the first information is used to indicate the number M of first transmission opportunities, where the number M of first transmission opportunities is used to determine the first transmission opportunity.

[0110] The second information is used to indicate that uplink transmission is performed on the first uplink resource. The uplink transmission between the first part and the second part included in the first time period of the first uplink resource satisfies the phase deviation and / or power deviation conditions described below, so that the access network device can perform filtering for a longer time in the first time period.

[0111] In other words, the second information is used to indicate a target channel or a target signal, and when the terminal device performs uplink transmission on the target channel or the resource used to send the target signal, phase control and / or power control is performed in the following steps. The target channel can be any of the above-mentioned PUSCH or PUCCH, and the target signal can be SRS.

[0112] The second information may be two-bit information, for example, 00 is used to indicate PUSCH, and 01 is used to indicate PUCCH. Alternatively, the second information may be 1 bit in the PUSCH scheduling DCI, indicating that the scheduled PUSCH is the target channel. Alternatively, the second information may be 1 bit in the PDSCH scheduling DCI, indicating that the PUCCH carrying the ACK / NACK corresponding to the scheduled PDSCH is the target channel. The specific form of the second information may also be other forms, and its protection scope is not limited thereto.

[0113] The first information and the second information may be sent through the same message, or through different messages. For example, the first information is sent through a fourth message, and the fourth message may be RRC signaling, or MAC-CE, or DCI, etc. The second information is sent through a fifth message, and the fifth message may be RRC signaling, or MAC-CE, or DCI, etc. In another implementation, the first information and the second information may be jointly indicated. For example, two-bit information is used to indicate the target channel and the number M of the first transmission opportunities. For example, 00 indicates that the target channel is PUSCH, and the number M of the first transmission opportunities is the number of transmission opportunities included in one transmission of the PUSCH, for example, 6.

[0114] It should be noted that, in some embodiments, the first information may also be sent through the following first message, that is, the first information is carried in the first message. In other embodiments, the second information may also be sent through the following first message, that is, the second information is carried in the first message. For example, the second information may be 1 bit in the DCI of the scheduled PUSCH, indicating that the scheduled PUSCH is the target channel. In other embodiments, both the first information and the second information are sent through the following first message, that is, the first information and the second information are carried in the first message.

[0115] Step 202: The access network device sends a first message to the terminal device.

[0116] The terminal device receives a first message sent by the access network device. The first message is used to configure a first uplink resource. The first message is used to configure the time-frequency domain position of the first uplink resource (eg, the target channel or target signal as described above). For a detailed explanation of step 202, see Figure 3 Step 101 of the illustrated embodiment will not be described in detail here.

[0117] It should be noted that the order of step 201 and step 202 is not limited by the size of the sequence number. For example, step 202 may be performed first, and then step 201.

[0118] Step 203: The terminal device determines a first time period based on at least one of the first information and the second information, and the time domain position of the first uplink resource.

[0119] The first time period is the time between the start and the end of the first uplink resource within a first time length, or the first time period is the time between the start and the end of the first uplink resource within a first transmission opportunity.

[0120] In one achievable method, the access network device sends the above-mentioned first information to the terminal device, and the terminal device determines the first time period based on the first information and a preset target channel or target signal, and the time domain position of the first uplink resource.

[0121] Another possible implementation method is that the access network device sends the second information to the terminal device, and the terminal device determines the first time period based on the second information, a preset first time length or a first transmission opportunity, and a time domain position of the first uplink resource.

[0122] In another possible implementation, the access network device sends the first information and the second information to the terminal device, and the terminal device determines the first time period according to the second information and the second information, as well as the time domain position of the first uplink resource.

[0123] For example, the time length of the first time period determined by the terminal device is greater than 1 time slot.

[0124] Taking the way in which the access network device sends the first information and the second information to the terminal device as an example, the first information configures the first time length as 2 time slots, the second information configures the target channel as PUSCH, and the first message configuration is as follows: Figure 4A The time-frequency domain resources of the PUSCH shown in FIG. 20 are as follows: Figure 4A The first time period is the time between the start and end of the PUSCH in two time slots.

[0125] The first information is used to indicate the number M of first transmission opportunities, and the number M of the first transmission opportunities is used to determine the explanation of the first transmission opportunity. The first uplink resource includes P transmission opportunities, and the P transmission opportunities can be divided into K groups. When P is less than or equal to M, K is 1, and the first transmission opportunity is the P transmission opportunities. When P is greater than M, the first transmission opportunities of the first K-1 groups in the K groups include M transmission opportunities, and the first transmission opportunity of the Kth group includes P-(K-1)*M transmission opportunities. is the ceiling operator.

[0126] For example, the first information configures the number M of the first transmission opportunities to be 3, the second information configures the target channel to be PUSCH, and the first message configuration is as follows: Figure 4B The time-frequency domain resources of a PUSCH transmission are shown in FIG. 1 . A PUSCH transmission includes 6 (P=6) transmission opportunities, then K=2. Through step 203, the terminal device can determine the following: Figure 4B The first time period is the time between the start and the end of each of the three transmission opportunities of the PUSCH.

[0127] Step 204: The terminal device performs uplink transmission on the first uplink resource.

[0128] The first uplink resource includes at least a first part and a second part in a first time period. The uplink transmission between the first part and the second part may satisfy at least one of the following: a phase deviation of the uplink transmission between the first part and the second part is within a first threshold range, or a power deviation of the uplink transmission between the first part and the second part is within a second threshold range.

[0129] When the terminal device performs uplink transmission on the first uplink resource, the phase and / or power of the uplink transmission of the first uplink resource within the first time period can be controlled. The terminal device can ensure that the phase of the uplink transmission of the first uplink resource within the first time period is continuous, or the phase deviation is within a certain range, by controlling the phase deviation of the uplink transmission between the first part and the second part within the first time period to be within the first threshold range, and / or, by controlling the power deviation of the uplink transmission between the first part and the second part within the first time period to be within the second threshold range, so that the access network device can perform filtering within the first time period, thereby improving the channel estimation quality.

[0130] In this embodiment, the access network device sends at least one of the first information or the second information to the terminal device, where the first information is used to indicate a first time length, or the first information is used to indicate the number M of first transmission opportunities, and the number M of first transmission opportunities is used to determine the first transmission opportunity. The access network device sends a first message to the terminal device, where the first message is used to configure a first uplink resource. The terminal device determines a first time period based on at least one of the first information and the second information, and the time domain position of the first uplink resource. When the terminal device performs uplink transmission on the first uplink resource, the phase deviation of the uplink transmission between the first part and the second part in the first time period is controlled to be within a first threshold range, and / or the power deviation of the uplink transmission between the first part and the second part in the first time period is controlled to be within a second threshold range, thereby ensuring that the phase of the uplink transmission of the first uplink resource in the first time period is continuous, or the phase deviation is within a certain range, so that the access network device can perform filtering in the first time period, thereby improving the channel estimation quality.

[0131] The embodiments of the present application can achieve the following methods to control the phase deviation of the uplink transmission between the first part and the second part in the first time period to be within a first threshold range, and / or control the power deviation of the uplink transmission between the first part and the second part in the first time period to be within a second threshold range.

[0132] Method 1: The terminal device does not receive downlink information during the first time period.

[0133] For the time division duplex (TDD) mode, the terminal device may not receive downlink information in the first time period, that is, ignore the downlink information. By not receiving downlink information in the first time period, the phase jump of the uplink transmission caused by the uplink and downlink switching can be avoided, ensuring that the phase of the uplink transmission of the first uplink resource in the first time period is continuous, or the phase deviation is within a certain range, so that the access network device can perform filtering in the first time period, thereby improving the channel estimation quality.

[0134] Method 2: The terminal device does not send uplink information of other uplink resources in the first time period. For example, the first uplink resource is PUSCH, and the terminal device does not send uplink information of other uplink resources except PUSCH in the first time period, for example, does not send uplink information of PUCCH in the first time period. A specific embodiment is used below to explain Method 2.

[0135] Figure 6 is a flowchart of another uplink sending method according to an embodiment of the present application. The method according to this embodiment involves a terminal device and an access network device. Figure 3 or Figure 5On the basis of Figure 6 As shown, the method of this embodiment may further include:

[0136] Step 301: The access network device sends a second message to the terminal device.

[0137] The terminal device receives a second message sent by the access network device, where the second message is used to configure a second uplink resource, and the second uplink resource is used to send second uplink information.

[0138] The first uplink resource in the above embodiment is used to send first uplink information, and the second uplink resource in this embodiment is used to send second uplink information. The first uplink information and the second uplink information are information of different types of uplink physical layer channels or different types of uplink physical layer signals, or one of the first uplink information and the second uplink information is information of an uplink physical layer channel and the other is an uplink physical layer signal, or the first uplink information and the second uplink information belong to different power control processes, or the first uplink information and the second uplink information are information of the same type of uplink physical layer channels and correspond to different hybrid automatic repeat request (HARQ) identification numbers.

[0139] For example, the first uplink information is uplink data carried on PUSCH, the second uplink information is uplink information carried on PUCCH, the first uplink information and the second uplink information are information of different types of uplink physical layer channels, in other words, the uplink physical layer channel of the first uplink information and the uplink physical layer channel of the second uplink information are different types of channels.

[0140] For example, Figure 4A The PUSCH 1 or PUSCH 2 shown in FIG. 1 belongs to a different power control process from the PUSCH 3 or PUSCH 4. The first uplink information is carried on the Figure 4A The uplink data on PUSCH 1 or PUSCH 2 shown in FIG. 1 is carried on the uplink data on PUSCH 1 or PUSCH 2 shown in FIG. Figure 4A The uplink data on PUSCH 3 or PUSCH 4 shown, the first uplink information and the second uplink information belong to different power control processes.

[0141] Step 302: The terminal device determines not to send second uplink information on the second uplink resource within the first time period.

[0142] The second message is used to configure Figure 4A Taking the PUCCH shown as an example, the second uplink resource is PUCCH, and the terminal device determines not to send the second uplink information on the PUCCH within the first time period, that is, no uplink transmission is performed on the PUCCH within the first time period.

[0143] In this embodiment, the terminal device determines not to send the second uplink information on the second uplink resource within the first time period, thereby controlling the phase deviation of the uplink transmission between the first part and the second part within the first time period to be within a first threshold range, and / or controlling the power deviation of the uplink transmission between the first part and the second part within the first time period to be within a second threshold range, ensuring that the phase of the uplink transmission of the first uplink resource within the first time period is continuous, or the phase deviation is within a certain range, so that the access network device can perform filtering within the first time period, thereby improving the channel estimation quality.

[0144] Mode 3: The terminal device does not send uplink information of periodic or semi-continuous uplink resources in the first time period, and sends uplink information of dynamically scheduled uplink resources by power control. A specific embodiment is used below to explain Mode 3.

[0145] Figure 7 is a flowchart of another uplink sending method according to an embodiment of the present application. The method according to this embodiment involves a terminal device and an access network device. Figure 3 or Figure 5 On the basis of Figure 7 As shown, the method of this embodiment may further include:

[0146] Step 401: The access network device sends a second message to the terminal device.

[0147] The terminal device receives a second message sent by the access network device, where the second message is used to configure a second uplink resource, and the second uplink resource is used to send second uplink information.

[0148] The explanation of step 401 can be found in Figure 6 Step 301 of the illustrated embodiment will not be described in detail here. It should be noted that the second uplink resource of this embodiment is a periodic or semi-persistent uplink resource.

[0149] Step 402: The access network device sends a third message to the terminal device.

[0150] The terminal device receives a third message sent by the access network device, where the third message is used to configure a third uplink resource, where the third uplink resource is a dynamically scheduled uplink resource, and where the third uplink resource is used to send third uplink information.

[0151] Step 403: The terminal device determines not to send the second uplink information on the second uplink resource within the first time period.

[0152] Step 404: The terminal device sends third uplink information on the third uplink resource.

[0153] A power deviation of uplink transmissions of the third uplink resource and the first uplink resource in the first time period is within a second threshold range, or a phase deviation of uplink transmissions is within a first threshold range.

[0154] That is, the terminal device ignores the uplink transmission of the periodic or semi-continuous uplink resources in the first time period, and for the dynamically scheduled uplink resources, the power or phase of its uplink transmission is affected by the power or phase of the uplink transmission of the first uplink resource in the first time period, so as to ensure that the power or phase of the uplink transmission in the first time period is the same or approximately the same. The approximately the same means that the power deviation or phase deviation of the uplink transmission in the first time period is within a certain threshold range, such as [-0.5, 0.5].

[0155] Among them, the above-mentioned first uplink information and the third uplink information are information of different types of uplink physical layer channels or different types of uplink physical layer signals, or one of the first uplink information and the third uplink information is information of an uplink physical layer channel, and the other is an uplink physical layer signal, or the first uplink information and the third uplink information belong to different power control processes, or the first uplink information and the third uplink information are information of the same type of uplink physical layer channel and correspond to different hybrid automatic repeat request identification numbers.

[0156] In this embodiment, the terminal device determines not to send the second uplink information on the second uplink resource within the first time period, and sends the third uplink information on the third uplink resource, the power deviation of the uplink transmission between the third uplink resource and the first uplink resource in the first time period is within the second threshold range, or the phase deviation of the uplink transmission is within the first threshold range, thereby controlling the phase deviation of the uplink transmission between the first part and the second part in the first time period to be within the first threshold range, and / or controlling the power deviation of the uplink transmission between the first part and the second part in the first time period to be within the second threshold range, ensuring that the phase of the uplink transmission of the first uplink resource in the first time period is continuous, or the phase deviation is within a certain range, so that the access network device can perform filtering in the first time period, thereby improving the channel estimation quality.

[0157] Mode 4: The terminal device transmits uplink information of all uplink resources in the first time period by means of power control. Mode 4 is explained below using a specific embodiment.

[0158] Figure 8 is a flowchart of another uplink sending method according to an embodiment of the present application. The method according to this embodiment involves a terminal device and an access network device. Figure 3 or Figure 5 On the basis of Figure 8 As shown, the method of this embodiment may further include:

[0159] Step 501: The access network device sends a second message to the terminal device.

[0160] The terminal device receives a second message sent by the access network device, where the second message is used to configure a second uplink resource, and the second uplink resource is used to send second uplink information.

[0161] The explanation of step 401 can be found in Figure 6 Step 301 of the illustrated embodiment will not be described in detail here.

[0162] Step 502: The terminal device sends second uplink information on a second uplink resource.

[0163] A power deviation of uplink transmissions of the second uplink resource and the first uplink resource in the first time period is within a second threshold range, or a phase deviation of uplink transmissions is within a first threshold range.

[0164] The first uplink resource is used to send first uplink information, the first uplink information and the second uplink information are information of different types of uplink physical layer channels or different types of uplink physical layer signals, or one of the first uplink information and the second uplink information is information of an uplink physical layer channel and the other is an uplink physical layer signal, or the first uplink information and the second uplink information belong to different power control processes, or the first uplink information and the second uplink information are information of the same type of uplink physical layer channel and correspond to different hybrid automatic repeat request identification numbers.

[0173] Sending a seventh message to the terminal device, where the seventh message is used to dynamically schedule a second uplink resource, where the second uplink resource is used to receive second uplink information;

[0174] The first uplink resource is used to receive first uplink information, the first uplink information and the second uplink information are information of different types of uplink physical layer channels or different types of uplink physical layer signals, or the first uplink information and the second uplink information belong to different power control processes.

[0175] In this embodiment, the access network device may avoid the phase jump of the uplink transmission of the terminal device by not dynamically scheduling the first downlink resource in the first time period. Alternatively, the access network device may avoid the phase jump of the uplink transmission of the terminal device by not sending downlink information to the terminal device through the periodic or semi-continuous second downlink resource in the first time period.
