Description

TECHNICAL FIELD

[0001] This application relates to communication technologies and, in particular, to an uplink transmission method and apparatus.

BACKGROUND OF THE ART

[0002] New Radio (NR) generally uses high frequency band for communication, and can achieve high speed and low latency data transmission to meet user usage requirements.

[0003] If the high frequency band is used, uplink coverage is limited. To solve the problem of limited uplink coverage, channel estimation quality is improved and uplink coverage is expanded. Typically, the technique of increasing the density of reference signals (RS) is used to improve the quality of channel estimation. For example, in NR, in addition to the main demodulation reference signals (DMRS), additional DMRS is configured.

[0004] However, in the manner described above, the overhead of DMRS resources increases, and this affects the utilization of uplink spectrum.

SUMMARY OF THE INVENTION

[0005] Embodiments of the present application provide an uplink transmission method and apparatus for improving channel estimation quality without adding an additional DMRS, so that the DMRS resource overhead is reduced and uplink spectrum utilization is improved.

[0006] According to a first aspect, an embodiment of the present application provides an uplink transmission method. The method may include: receiving a first message sent by a network access device, where the first message is used to configure a first uplink resource; and performing uplink transmission on the first uplink resource.

[0007] The first uplink resource includes at least a first part and a second part in a first time period. The phase deviation of the uplink transmission between the first part and the second part is within the first threshold range, and/or the deviation of the uplink transmission power between the first part and the second part is within the second threshold range. The first time period represents the duration between the start time and the end time of the first uplink resource in the first time duration, or the first time period represents the duration between the start time and the end time of the first uplink resource in the first transmission opportunity. The first part and the second part correspond to 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 slots.

[0008] In this implementation, the uplink transmission phase deviation between the first part and the second part is controlled to be within the first threshold range, and/or the uplink transmission power deviation between the first part and the second part is controlled so that it is within the first threshold range. so that it is within the second threshold range. Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage. In this method, no additional DMRS needs to be added, so the DMRS resource overhead is reduced and uplink spectrum utilization is improved.

[0009] In an exemplary implementation, the first threshold range is determined based on the time domain interval between the first part and the second part, and/or the second threshold range is determined based on the interval between slots in which the first part and the second part are located.

[0010] In this implementation, the first threshold range is determined based on the time domain interval between the first part and the second part, and then the phase deviation of the uplink transmission between the first part and the second part is controlled to be within the first threshold range based on the first threshold range. Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage.

[0011] The second threshold range is determined based on the interval between the slots in which the first part and the second part are located, and then the uplink transmission power deviation between the first part and the second part is controlled to be within the second threshold range based on second threshold range. Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage.

Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage.

[0014] In an exemplary embodiment, the method may further include: receiving second information sent by a network access device, where the second information indicates an uplink transmission is being performed on a first uplink resource.

[0015] In this implementation, the network access device indicates a target channel or target signal, such that the network access device controls, based on the indication of the network access device, the uplink transmission phase and/or power of the target channel or target signal. Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage.

[0016] In an exemplary embodiment, the first uplink resource includes P transmission capabilities, and the P transmission capabilities are divided into K groups. When P is less than or equal to M, K is 1, and the first transmission opportunity is P transmission opportunities. When P is greater than M, the first transmission opportunities of the first K - 1 groups in K groups include M transmission opportunities, and the first transmission opportunity of the Kth group includes P - (K - 1) * M transmission opportunities, where K , A - rounding operator up.

[0017] In this implementation, the first transmission opportunities of the K groups may be determined based on the number M of first transmission opportunities and the number P of transmission opportunities of the first uplink resource, and the first time period is determined based on the first transmission opportunities of the K groups for additional phase control and /or the uplink transmit power on the first uplink resource in the first time period.

The number of core network devices, the number of radio access network devices, and the number of terminal devices included in the mobile communication system are not limited in embodiments of the present application.

[0064] Embodiments of the present application may be applied to downlink signal transmission, may be applied to uplink signal transmission, or may be applied to device to device (D2D) signal transmission. For transmitting a downlink signal, the transmitting device is a radio access network device, and the receiving device is correspondingly a terminal device.

[0066] FIG. 2 is a schematic diagram of some modules used in uplink transmission in accordance with an embodiment of the present application. As shown in FIG. 2, some modules used in 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 generating unit 11 of the BBIC 1 is configured to generate a normalized baseband signal, and the gain calculation unit 12 calculates the gain of the normalized baseband signal. The gain calculation unit 12 sends the gain to RFIC 2. RFIC 2 implements by two-level adjustment in the digital domain (digital domain amplifier 21 shown in FIG. 2) and in the analog domain (analog domain amplifier 23 shown in FIG. 2) gain transmitted by the calculation module.

[0067] Gain adjustment or on/off in the analog domain causes a phase jump in the uplink transmission. Gain control in the digital domain does not cause phase jump in uplink transmission. However, the digital domain gain control module should not make much adjustment because excessive digital domain power causes saturation of the digital to analog converter (DAC) 22, and excessively low digital domain power reduces the efficiency of the DAC. . It should be ensured that the digital domain power supplied to the DAC 22 is relatively stable around the value.

[0068] Adjusting the uplink transmit power causes analog domain gain adjustment, and enabling/disabling the uplink analog domain enables/disables the analog domain gain module. Consequently, an uplink transmission phase jump occurs.

Embodiments of the present application provide an uplink transmission method. In this method, filtering is performed for a longer time in the time domain, so that the quality of the channel estimate is improved and the uplink coverage is improved. In this method, no additional DMRS is required to be added, so that the DMRS resource overhead is reduced and uplink spectrum utilization is improved. In embodiments of the present application, the continuity of the uplink transmission phase within a period of time is realized using implementations of the following embodiments, so that filtering can be performed for a longer time in the time domain, and the quality of channel estimation is improved.

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. channel, PUCCH).

[0072] The PUSCH may include a PUSCH based on dynamic scheduling or configured PUSCH grant. For PUSCH based on dynamic scheduling, the terminal device receives uplink scheduling at a time, for example, receives radio resource control (RRC) signaling, medium access control-control element (MAC-CE) , or downlink control information (DCI), and the terminal device performs PUSCH transmission once based on uplink scheduling. The configured PUSCH grant is periodic, and each period may include one group of transmission occasions, eg, K transmission occasions. The configured grant PUSCH can be classified into a configured grant PUSCH type 1 (Type1) and a configured grant PUSCH type 2 (Type2). For a configured PUSCH grant type 1 (Type1), the network access device may configure some semi-persistent resources for the terminal device using RRC signaling. If a terminal device needs to transmit uplink data, the terminal device may use semi-persistent resources to perform the uplink transmission. If the terminal device does not need to transmit data on the uplink, the terminal device may not use semi-persistent resources to perform the uplink transmission. For a configured Type 2 PUSCH grant, the network access device can configure some semi-persistent resource parameters for the terminal device using RRC signaling, and then configure some semi-persistent resource parameters using physical layer signaling and activate the semi-persistent resource. - a persistent resource or can deactivate a semi-persistent resource using physical layer signaling. When the semi-persistent resource is activated, the terminal device can use the semi-persistent resource to perform uplink transmissions. When the semi-persistent resource is not activated or deactivated, the terminal device cannot use the semi-persistent resource to perform uplink transmission.

[0073] The PUCCH may be periodic, semi-persistent, or dynamically scheduled with a physical downlink shared channel (PDSCH).

[0074] SRS can be divided into three modes: periodic SRS, semi-permanent SRS and aperiodic SRS. For periodic SRS or semi-permanent SRS, the period per slot unit and the offset per slot are configured. Period value range: {1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320, 640, 1280, 2560}. For aperiodic SRS, the slot level offset is adjusted. Offset is the inter-slot gap between DCI initiation and actual SRS transmission. The offset can be any value from 0 to 32. When the offset is 0, it indicates that the DCI starts in the same slot as the transmitted SRS.

[0075] In the embodiments of the present application, an example is used for description in which the slot is a slot in the NR system, and the scope of protection of the embodiments of the present application is not limited to this.

[0076] A transmission occasion in embodiments of the present application may be one or more repetitions of uplink information. The repeated (repeatedly sent) uplink information herein may be a repeated physical uplink shared channel (PUSCH), a repeated physical uplink control channel (PUCCH), a repeated probe a sounding reference signal (SRS), or a repeating random access channel (RACH).

[0079] The terminal device receives the first message sent by the network access device. The first message is used to configure the first uplink resource.

[0080] The first uplink resource may be a resource carrying any uplink information, for example, any of 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-persistent, or periodic.

[0081] Dynamic scheduling in this embodiment of the present application refers to physical layer signaling scheduling, such as DCI scheduling. For example, the first uplink resource may be an uplink resource scheduled using DCI. The periodic resource in this embodiment of the present application is a periodic resource that is configured using RRC signaling and that can be used for or that is used for uplink transmission. For example, the first uplink resource may be a periodic resource that is configured using RRC signaling and that can be used for uplink transmission. The semi-persistent resource in this embodiment of the present application is a periodic resource that is configured using RRC signaling and which can be used for uplink transmission after the resource is activated using MAC-CE or DCI.

[0082] Step 102: The terminal device performs uplink transmission on the first uplink resource.

[0083] The network access device performs uplink reception on the first uplink resource.

[0084] 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: the phase deviation of the uplink transmission between the first part and the second part is within the first threshold range or the deviation of the uplink transmission power between the first part and the second part is within the second threshold range. In other words, the uplink transmission phase deviation between the first part and the second part is within the first threshold range, and/or the uplink transmission power deviation between the first part and the second part is within the second threshold range.

[0085] The first time period is the duration between the start time and the end time of the first uplink resource in the first time duration, or the first time period is the duration between the start time and the end time of the first uplink resource in the first transmission opportunity. It should be noted that the first duration of time in this embodiment of the present application may be a duration of time, for example, two slots. The first time duration can be any two slots in the time domain and does not matter the location in the time domain. The first time period not only has the meaning of time duration, but also has the meaning of location in the time domain. This is different from the first time duration. In other words, the first time period has a time period with a specific position in the time domain. In this embodiment of the present application, the first time period may be determined based on the first time duration and the time domain location of the first uplink resource. The first time duration may be preset or configured by the network access device. The first transmission opportunity may be a predetermined number of transmission opportunities (eg, M transmission opportunities) or transmitting the first uplink resource at a time (eg, transmitting a PUSCH at a time, and transmitting a PUSCH at a time may include multiple transmission opportunities). ). The first transmission capability may be predetermined or configured by the network access device.

[0086] For example, FIG. 4A is a schematic diagram of a first time period according to an embodiment of the present application. It is assumed that the first time duration is two slots, and the first uplink resource is PUSCH 1, PUSCH 2, PUSCH 3 and PUSCH 4, the first time period is the duration between the start time of PUSCH 1 and the end time of PUSCH 2 in two slots, and the duration between the PUSCH 3 start time and the PUSCH 4 end time in two slots.

[0087] FIG. 4B is a schematic diagram of another first time period according to an embodiment of the present application. It is assumed that the first uplink resource is a PUSCH, transmission of a PUSCH at one time includes six transmission opportunities, as shown in FIG. 4B, the six transmission opportunities are PUSCH 1, PUSCH 2, PUSCH 3, PUSCH 4, PUSCH 5 and PUSCH 6, and the first transmission opportunity represents every three transmission opportunities out of the six transmission opportunities. In this case, the first time period is the duration between the PUSCH start time and the PUSCH end time in three transmission possibilities. For example, as shown in FIG. 5, the first time period represents the duration between the PUSCH 1 start time and the PUSCH 3 end time, and the duration between the PUSCH 4 start time and the PUSCH 6 end time.

[0088] The first part and the second part correspond to 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 slots. A time domain resource unit can be one Tc, multiple Tcs, one Ts, multiple Ts, one symbol, multiple symbols, or a slot. Where Hz, and . Where And . Tc refers to the basic time unit for NR in NR and Ts refers to the basic time unit for LTE in LTE.

[0089] The time domain interval between the first part and the second part may be the interval between the final position of the first part in the time domain and the starting position of the second part in the time domain. N is used to represent the time domain interval between the first part and the second part. In some embodiments, N > 0. FIG. 4A is used as an example for further description. The first part may be PUSCH 1, the second part may be PUSCH 2, the time domain interval between the first part and the second part is interval 1 shown in FIG. 4A, and interval 1 is greater than 0 time domain resource units.

[0090] It should be noted that the first uplink resource includes at least a first part and a second part in a first time period. It can be understood that the first uplink resource may further include another portion in the first time period, for example, a third portion. The third part may be a time domain resource that carries no uplink information, or may be a time domain resource that carries other uplink information. Fig. 4A is used as an example for further description. In addition to the first part (PUSCH 1) and the second part (PUSCH 2), the first uplink resource (PUSCH) in the first time period further includes a PUCCH, a downlink resource (D), a soft symbol (F), and the like. similar. The flexible symbol is typically located between a downlink resource and an uplink resource, and the flexible symbol can be configured as a downlink symbol or an uplink symbol using physical layer signaling to flexibly support a traffic burst.

[0091] In this embodiment of the present application, frequency domain resources in the first part and the second part may be the same, so that time domain channel estimation filtering is performed in the first part and the second part.

[0092] In some other embodiments, N=0, that is, there is no time domain interval between the first part and the second part, and the first part and the second part are consecutive in the time domain. When there is no time domain interval between the first part and the second part, the first part and the second part are located in different slots. In other words, the ending position of the first part in the time domain is the last symbol of one slot, and the starting position of the second part in the time domain is the first symbol of the next slot.

[0093] The uplink transmission phase deviation in this embodiment of the present application is the difference between any two uplink transmission phase changes between the first part and the second part, and the phase changes can be generated by the above gain control in the analog domain. The phase deviation is within the first threshold range.

[0094] For example, the first threshold range may be [-a, a], and B represents the phase deviation of the uplink transmission between the first part and the second part. In this case, the corresponding value is B: -a < B < a, or -a ≤ B ≤ a.

[0095] In some embodiments, the first threshold range may be associated with a time domain interval between the first part and the second part. For example, the first threshold range could be [- (N+1) a, (N+1) a]. In this case, the corresponding value of B is: - (N+1) a < B < (N+1) a, or - (N+1) a ≤ B ≤ (N+1) a.

[0096] In some embodiments, the first threshold range may be preset or may be determined based on N. In other words, the first threshold range is determined based on the time domain interval between the first part and the second part. For example, a larger time domain interval between the first part and the second part indicates a larger first threshold range. For example, when the time domain interval between the first part and the second part is one symbol, the first threshold range is [-1, 1]. When the time domain interval between the first part and the second part is three symbols, the first threshold range is [-3, 3].

[0097] The uplink transmission phase deviation in this embodiment of the present application may alternatively be the difference in phase changes between the last time domain pilot symbol of the first part and the first time domain pilot symbol of the second part, and the phase changes may be formed by the above gain control in the analog domain. The phase deviation is within the first threshold range.

[0098] For example, the first threshold range may be [-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 . In this case, the corresponding value is B: -a < B < a, or -a ≤ B ≤ a.

[0099] In some embodiments, the first threshold range may be associated with 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 first threshold range could be [- (N+1) a, (N+1) a]. In this case, the corresponding value of B is: - (N+1) a < B < (N+1) a, or - (N+1) a ≤ B ≤ (N+1) a.

[00100] In some embodiments, the first threshold range may be preset or may be determined based on N. In other words, the first threshold range is determined based on the time domain interval between the last pilot symbol in the time domain of the first part and the first pilot symbol. signal in the time domain of the second part. For example, a larger 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 indicates a larger 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 one 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 three symbols, the first threshold range is [-3, 3].

[00101] The uplink transmission power deviation in this embodiment of the present application is the difference in uplink transmission power for any two times between the first part and the second part. This is similar to the phase deviation of uplink transmission. The power deviation is in the second threshold range. For example, the second threshold range may be [-c, c], and D represents the uplink transmission power deviation between the first part and the second part. In this case, the corresponding value is D: -c < D < c, or -c ≤ D ≤ c. For example, c could be 1 dB or any value less than 1, such as 0.5 dB.

[00102] In some embodiments, the second threshold range may be associated with a time domain interval between the first part and the second part. The second threshold range may be preset or may be determined based on N. In other words, the second threshold range is determined based on the time domain interval between the first part and the second part. For example, a larger time domain interval between the first part and the second part indicates a larger second threshold range.

[00103] For the first part, that is, for each symbol in the first part, the uplink transmission phase deviation of each symbol in the first part is within the first threshold range; for the second part, that is, for each symbol in the second part, the uplink transmission phase deviation of each symbol in the second part is within the first threshold range; and/or for the first part, the uplink transmission power deviation of each symbol in the first part is within the second threshold range, and for the second part, the uplink transmission power deviation of each symbol in the second part is within the second threshold range; and/or for the first part, the uplink transmission power of all symbols in the first part is the same, and for the second part, the uplink transmission power of all symbols in the second part is the same.

[00104] In some embodiments, the network access device receives on the uplink for the first uplink resource and performs channel estimation. The method in which the network access device performs channel estimation may be as follows: The network access device performs channel estimation for the first part based on the pilot signal of the first part, and performs channel estimation for the second part based on the pilot signal of the second part; the network access device performs channel estimation for the first part based on the pilot signal of the first part and performs channel estimation for the second part based on the pilot signal of the first part; or the network access device performs channel estimation for the second portion based on the pilot of the first portion, and performs channel estimation for the second portion based on the pilot of the second portion.

[00105] In this embodiment, the terminal device receives a first message sent by the network access device, where the first message is used to configure a first uplink resource, and the terminal device performs an uplink transmission on the first uplink resource. The first uplink resource includes at least a first portion and a second portion in a first time period. The uplink transmission between the first part and the second part may satisfy at least one of the following: the phase deviation of the uplink transmission between the first part and the second part is within the first threshold range or the deviation of the uplink transmission power between the first part and the second part is within the second threshold range. The terminal device controls the phase deviation of the uplink transmission between the first part and the second part so that it is within the first threshold range, and/or controls the deviation of the uplink transmission power between the first part and the second part so that it is within the second threshold range. threshold range. Thus, the network access device can perform filtering for a long time in the first time period to improve the channel estimation quality and improve uplink coverage. In this method, no additional DMRS is required to be added, so that the DMRS resource overhead is reduced and uplink spectrum utilization is improved.

[00106] FIG. 5 is a block diagram of another uplink transmission method according to an embodiment of the present application. The method in this embodiment relates to a terminal device and a network access device. In this embodiment, the network access device configures a first time duration or number M of first transmission opportunities, a target channel, or a target signal for the terminal device. As shown in FIG. 5, the method in this embodiment may include the following steps.

[00107] Step 201: The network access device sends at least one of the first information or the second information to the terminal device.

[00108] The terminal device receives first information sent by the network access device, where the first information indicates a first time duration, or the first information indicates a number M of first transmission opportunities, and the number M of first transmission opportunities is used to determine the first transmission opportunity.

[00109] The second information indicates that uplink transmission is being performed on the first uplink resource. The uplink transmission of the first uplink resource between the first part and the second part, which are included in the first period of time, satisfies the following conditions: phase deviations and/or power deviations, so that the network access device can perform filtering for a long time in the first period time.

[00110] In other words, the second information indicates the target channel or target signal, and when the terminal device performs uplink transmission on the target channel or resource to send the target signal, the terminal device performs phase control and/or power control through the following steps . The target channel may be any of the above PUSCH or PUCCH, and the target signal may be SRS.

[00111] The second information may be 2-bit information. For example, 00 indicates PUSCH and 01 indicates PUCCH. Alternatively, the second information may be 1 bit in the DCI for PUSCH scheduling to indicate that the scheduled PUSCH is the target channel. Alternatively, the second information may be 1 bit in the DCI for PDSCH scheduling to indicate that the PUCCH carrying the ACK/NACK corresponding to the scheduled PDSCH is the target channel. Alternatively, the specific form of the second information may be another form, and the scope of protection of the second information is not limited to this.

[00112] The first information and the second information may be sent using the same message or may be sent using different messages. For example, the first information is sent using a fourth message, and the fourth message may be RRC, MAC-CE, DCI, or the like signaling. The second information is sent using a fifth message, and the fifth message may be RRC, MAC-CE, DCI, or the like signaling. In another implementation, the first information and the second information may be indicated together. For example, the 2-bit information indicates the target channel and the number M of first transmission opportunities. For example, 00 indicates that the target channel is a PUSCH, and the number M of first transmission opportunities is the number of transmission opportunities included in the transmission for one PUSCH time. For example, the number M of first transmission opportunities may be 6.

[00113] It should be noted that in some embodiments, the first information may alternatively be sent using the next first message. In other words, the first information is conveyed in the first message. In some other embodiments, the second information may alternatively be sent using the following first message. To be precise, the second information is conveyed in the first message. For example, the second information may be 1 bit in the DCI for PUSCH scheduling to indicate that the scheduled PUSCH is the target channel. In some other embodiments, both the first information and the second information are sent using the following first message. In other words, the first information and the second information are carried in the first message.

[00114] Step 202: The network access device sends a first message to the terminal device.

[00115] The terminal device receives the first message sent by the network access device. The first message is used to configure the first uplink resource. The first message is used to set up a location in the time-frequency domain of a first uplink resource (eg, a target channel or target signal described above). For specific explanations and descriptions of step 202, refer to step 101 in the embodiment shown in FIG. 3. The details are not repeated here.

[00116] It should be noted that the sequence of step 201 and step 202 is not limited by sequence number. For example, step 202 may be performed before step 201.

[00117] Step 203: The terminal device determines a first time period based on the time domain location of the first uplink resource and at least one of the first information and the second information.

[00118] The first time period is the duration between the start time and the end time of the first uplink resource in the first time duration, or the first time period is the duration between the start time and the end time of the first uplink resource in the first transmission opportunity.

[00119] In an implementation, the network access device sends the first information to the terminal device, and the terminal device determines the first time period based on the first information, a predetermined target channel or target signal, and a time domain location of the first uplink resource.

[00120] In another implementation, the network access device sends the second information to the terminal device, and the terminal device determines the first time period based on the second information, a predetermined first time duration or first transmission opportunity, and the time domain location of the first uplink resource.

[00121] In yet another exemplary implementation, the network access device sends the first information and the second information to the terminal device, and the terminal device determines the first time period based on the first information and the second information, as well as a time domain location of the first uplink resource.

[00122] For example, the duration of the first time period determined by the terminal device exceeds one slot.

[00123] The method in which the network access device sends the first information and the second information to the terminal device is used as an example for description. The first time duration configured using the first information is two slots, the target channel configured using the second information is PUSCH, and the time frequency domain resource PUSCH shown in FIG. 4A is configured using the first message. Step 203 is performed so that the terminal device can determine the first time period shown in FIG. 4A. The first time period represents the duration between the start time and the end time of the PUSCH in two slots.

[00124] The first information indicates the number M of first transmission opportunities, and the number M of first transmission opportunities is used to determine the first transmission opportunity. The first uplink resource includes P transmission capabilities, and the P transmission capabilities may be divided into K groups. When P is less than or equal to M, K is 1, and the first transmission opportunity is P transmission opportunities. When P is greater than M, the first transmission opportunities of the first K - 1 groups in K groups include M transmission opportunities, and the first transmission opportunity of the Kth group includes P - (K - 1) * M transmission opportunities, where K , A - rounding operator up.

[00125] For example, the number M of first transmission capabilities configured using the first information is 3, the target channel configured using the second information is PUSCH, the first message configures a time-frequency domain resource to transmit PUSCH for one time shown in Fig. 4B, and transmission of PUSCH at one time includes 6 (P=6) transmission opportunities. In this case, K = 2. Step 203 is performed so that the terminal device can determine the first time period shown in FIG. 4B. The first time period represents the duration between the start time and the end time of the PUSCH in every three transmission opportunities.

[00126] Step 204: The terminal device performs an uplink transmission on a first uplink resource.

[00127] 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: the phase deviation of the uplink transmission between the first part and the second part is within the first threshold range or the deviation of the uplink transmission power between the first part and the second part is within the second threshold range.

[00128] When a terminal device performs uplink transmission on a first uplink resource, the terminal device may control the phase and/or power of the uplink transmission on the first uplink resource in a first time period. The terminal device may control the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it is within the first threshold range, and/or control the deviation of the uplink transmission power between the first part and the second part in the first time period. a period of time so that it is within a second threshold range to ensure that uplink transmission phases on the first uplink resource in the first time period are continuous or phase deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00129] In this embodiment, the network access device sends to the terminal device at least one of the first information or the second information, where the first information indicates a first time duration, or the first information indicates the number M of first transmission opportunities, and the number M of first transmission opportunities is used for determining the first transfer opportunity. The network access device sends a first message to a terminal device, where the first message is used to configure a first uplink resource. The terminal device determines the first time period based on at least one of the first information and the second information and the time domain location of the first uplink resource. When the terminal device performs uplink transmission on the first uplink resource, the terminal device controls the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it is within the first threshold range, and/or controls deviation of the uplink transmission power between the first part and the second part in the first time period so that it is within the second threshold range to ensure that the uplink transmission phases of the first uplink resource in the first time period are continuous or phasic deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00130] In this embodiment of the present application, the uplink transmission phase deviation between the first part and the second part in the first time period can be controlled to be within the first threshold range, and/or the uplink transmission power deviation between the first portion and the second portion in the first time period can be controlled to be within the second threshold range in the following several ways.

[00131] In the first case, the terminal device does not receive downlink information in the first time period.

[00132] For time division duplex (TDD) mode, the terminal device may not receive downlink information in the first time period. In other words, the terminal device ignores the downlink information. Downlink information is not received in the first time period to avoid uplink transmission phase jump caused by switching from uplink to downlink, and to ensure that uplink transmission phases on the first uplink resource are in the first period of time are continuous or the phase deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00133] In the second case, the terminal device does not send uplink information on another uplink resource in the first time period. For example, the first uplink resource is PUSCH, and the terminal device does not send uplink information about an uplink resource other than PUSCH in the first time period. For example, the terminal device does not send uplink PUCCH information in the first time period. The second case is explained and described below using a specific embodiment.

[00134] FIG. 6 is a block diagram of another uplink transmission method according to an embodiment of the present application. The method in this embodiment relates to a terminal device and a network access device. Based on FIG. 3 or fig. 5, in this embodiment, as shown in FIG. 6, the method in this embodiment may further include the following steps:

[00135] Step 301: The network access device sends a second message to the terminal device.

[00136] The terminal device receives a second message sent by the network access device, wherein the second message is used to configure a second uplink resource, and the second uplink resource is used to send second uplink information.

[00137] The first uplink resource in the previous embodiment is used to send the first uplink information, and the second uplink resource in this embodiment is used to send the second uplink information. The first uplink information and the second uplink information are information about different types of uplink physical layer channels or different types of uplink physical layer signals. Alternatively, one of the first uplink information and the second uplink information is uplink physical layer channel information, and the other is an uplink physical layer signal. Alternatively, the first uplink information and the second uplink information belong to different power control processes. Alternatively, the first uplink information and the second uplink information are information about the same type of uplink physical layer channels and correspond to different Hybrid Automatic Retransmission Request (HARQ) identification numbers.

[00138] For example, the first uplink information represents uplink data carried on the PUSCH, the second uplink information represents uplink information carried on the PUCCH, and the first uplink information and the second uplink information represent provides information about the different types of uplink physical layer channels. In other words, the uplink physical layer channel for the first uplink information and the uplink physical layer channel for the second uplink information are different types of channels.

[00139] For example, PUSCH 1 or PUSCH 2 shown in FIG. 4A, and PUSCH 3 or PUSCH 4 belong to different power control processes. The first uplink information is uplink data carried on PUSCH 1 or PUSCH 2 shown in FIG. 4A. The second uplink information is uplink data carried on PUSCH 3 or PUSCH 4 shown in FIG. 4A. The first uplink information and the second uplink information belong to different power control processes.

[00140] Step 302: The terminal device decides not to send the second uplink information on the second uplink resource in the first time period.

[00141] For example, the second message is used to configure the PUCCH shown in FIG. 4A. In this case, the second uplink resource is the PUCCH, and the terminal device decides not to send the second uplink information on the PUCCH in the first time period. In other words, the terminal device does not perform uplink transmission on the PUCCH in the first time period.

[00142] In this embodiment, the terminal device decides not to send the second uplink information on the second uplink resource in the first time period to monitor the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it was within the first threshold range, and/or control the deviation of the uplink transmission power between the first part and the second part in the first time period so that it was within the second threshold range, and ensure that the uplink transmission phases in the first The uplink resource in the first period of time is continuous or the phase deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00143] In the third method, the terminal device does not send uplink information about the periodic or semi-persistent uplink resource in the first time period, but sends uplink information about the dynamically scheduled uplink resource in a power control manner. The third method is explained and described below using a specific embodiment.

[00144] FIG. 7 is a block diagram of another uplink transmission method according to an embodiment of the present application. The method in this embodiment relates to a terminal device and a network access device. Based on FIG. 3 or fig. 5, in this embodiment, as shown in FIG. 7, the method in this embodiment may further include the following steps:

[00145] Step 401: The network access device sends a second message to the terminal device.

[00146] The terminal device receives a second message sent by the network access 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.

[00147] For an explanation and description of step 401, refer to step 301 in the embodiment shown in FIG. 6. The details are not repeated here. It should be noted that the second uplink resource in this embodiment is a periodic or semi-persistent uplink resource.

[00148] Step 402: The network access device sends a third message to the terminal device.

[00149] The terminal device receives a third message sent by the network access device, wherein the third message is used to configure a third uplink resource, the third uplink resource is a dynamically scheduled uplink resource, and the third uplink resource is used to send third uplink information.

[00150] Step 403: The terminal device decides not to send the second uplink information on the second uplink resource in the first time period.

[00151] Step 404: The terminal device sends third uplink information on a third uplink resource.

[00152] The uplink transmission power deviation in the third uplink resource and the first uplink resource in the first time period is within the second threshold range, or the uplink transmission phase deviation is within the first threshold range.

[00153] Specifically, the terminal device ignores uplink transmission of a periodic or semi-persistent uplink resource in the first time period. For a dynamically scheduled uplink resource, the uplink transmission power or phase of the dynamically scheduled uplink resource depends on the uplink transmission power or phase of the first uplink resource in the first time period to ensure that the uplink transmission power or phase the uplink on the dynamically scheduled uplink resource and the first uplink resource in the first time period are the same or approximately the same. It roughly means that the power deviation or phase deviation of the uplink transmission in the first time period is within a certain threshold range, for example [-0.5, 0.5].

[00154] The first uplink information and the third uplink information are information about different types of uplink physical layer channels or different types of uplink physical layer signals. Alternatively, one of the first uplink information and the third uplink information is uplink physical layer channel information, and the other is an uplink physical layer signal. Alternatively, the first uplink information and the third uplink information belong to different power control processes. Alternatively, the first uplink information and the third uplink information are information about the same type of uplink physical layer channels and correspond to different hybrid automatic retransmission request identification numbers.

[00155] In this embodiment, the terminal device determines that the second uplink information should not be sent for the second uplink resource in the first time period, and sends the third uplink information for the third uplink resource, wherein the transmission power deviation on the uplink for 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, so as to control the phase deviation of the uplink transmission communication between the first part and the second part in the first time period so that it is within the first threshold range, and/or the uplink transmission power deviation between the first part and the second part in the first time period is controlled so as to be within the second threshold range, and ensures that the uplink transmission phases to the first uplink resource in the first time period are continuous or the phase deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00156] In a fourth method, the terminal device sends uplink information about all uplink resources in a power control manner in a first time period. The fourth method is explained and described below using a specific embodiment.

[00157] FIG. 8 is a block diagram of another uplink transmission method according to an embodiment of the present application. The method in this embodiment relates to a terminal device and a network access device. Based on FIG. 3 or fig. 5, in this embodiment, as shown in FIG. 8, the method in this embodiment may further include the following steps:

[00158] Step 501: The network access device sends a second message to the terminal device.

[00159] The terminal device receives a second message sent by the network access device, wherein the second message is used to configure a second uplink resource, and the second uplink resource is used to send second uplink information.

[00160] For an explanation and description of step 401, refer to step 301 in the embodiment shown in FIG. 6. The details are not repeated here.

[00161] Step 502: The terminal device sends second uplink information on a second uplink resource.

[00162] The uplink transmission power deviation on the second uplink resource and the first uplink resource in the first time period is within the second threshold range, or the uplink transmission phase deviation is within the first threshold range.

[00163] The first uplink resource is used to send first uplink information. The first uplink information and the second uplink information are information about different types of uplink physical layer channels or different types of uplink physical layer signals. Alternatively, one of the first uplink information and the second uplink information is uplink physical layer channel information, and the other is an uplink physical layer signal. Alternatively, the first uplink information and the second uplink information belong to different power control processes. Alternatively, the first uplink information and the second uplink information are information about the same type of uplink physical layer channels and correspond to different hybrid automatic retransmission request identification numbers.

[00164] Specifically, for uplink transmission on another uplink resource different from the first uplink resource, in a first time period, the power or phase of the uplink transmission on the other uplink resource depends on the power or phase of the transmission on the uplink on the first uplink resource in the first time period to ensure that the power or phases of uplink transmission on the other resource and the first uplink resource in the first time period are the same or approximately the same. For an explanation and description of “about the same,” refer to the explanation and description at step 404. The details are not repeated here.

[00165] In this embodiment, the terminal device controls the power or phase of the uplink transmission on another uplink resource different from the first uplink resource in a first time period to control the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it is within the first threshold range, and/or controls the deviation of the uplink transmission power between the first part and the second part in the first time period so that it is within the second threshold range, and ensuring that the uplink transmission phases to the first uplink resource in the first time period are continuous or the phase deviations are within a certain range. Thus, the network access device may perform filtering in the first time period to improve the quality of the channel estimate.

[00166] It should be noted that the above-mentioned first to fourth methods may be used individually or may be used in combination. Examples are not listed in this embodiment of this application.

[00167] The first to fourth methods are used from the point of view of a terminal device to control the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it is within the first threshold range, and/or control the deviation of the transmit power the uplink between the first part and the second part in the first time period must be within the second threshold range. In this embodiment of the present application, the following fifth method may be further used from the point of view of the network access device to control the phase deviation of the uplink transmission between the first part and the second part in the first time period so that it is within the first threshold range and/or control the deviation of the uplink transmission power between the first part and the second part in the first time period so that it is within the second threshold range.

[00168] In a fifth method, the network access device determines not to do at least one of the following in the first time period:

sending a sixth message to the terminal device, wherein the sixth message is used to dynamically schedule a first downlink resource and the first downlink resource is used to send downlink information;

sending downlink information to the terminal device using the dynamically scheduled first downlink resource;

sending downlink information to the terminal device using a periodic or semi-persistent second downlink resource; or

sending a seventh message to the terminal device, wherein the seventh message is used to dynamically schedule a second uplink resource, and the second uplink resource is used to receive second uplink information.

[00169] A first uplink resource is used to receive first uplink information. The first uplink information and the second uplink information are information about 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 .

[00170] In this embodiment, the network access device may not dynamically schedule the first downlink resource in the first time period to avoid jumping the uplink transmission phase of the terminal device. Alternatively, the network access device may not send downlink information to the terminal device using a periodic or semi-persistent second downlink resource in the first time period to avoid jumping the uplink transmission phase of the terminal device. Alternatively, the network access device may not dynamically schedule another uplink resource different from the first uplink resource in the first time period to avoid jumping the uplink transmission phase of the terminal device.
