Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technologies, and particularly relates to an uplink transmission method, a terminal, and a network-side device. Background Art
[0002] When sounding reference signal (SRS) antenna rotation is performed, there is no defined metric in radio resource management (RRM).

[0038] Next, in combination with the accompanying drawings, the uplink transmission method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.
[0039] As Figure 3 shown, the embodiments of the present application provide an uplink transmission method, including but not limited to the following steps:
[0040] Step 31: The terminal sends first information to the network-side device, and the first information is used to indicate the interval time required for the antenna switching process.
[0041] Among them, the interval time can also be referred to as delay. The interval time required for the antenna switching process indicated by the first information is the maximum of the interval times required for the antenna switching process under different uplink transmission power requirements and / or peak-to-average power ratio requirements. The interval time required for the antenna switching process includes the switch switching and power switching interval times. Specifically, the antenna switching process may include a switch switching process and a power switching process. Taking the switching from antenna y to antenna x as an example, the antenna switching process includes the whole process of adjusting the PA power from the normal transmission power to the off state, adjusting the antenna switching switch state, and adjusting the PA power from the off state to the normal transmission state. Correspondingly, the interval time required for the antenna switching process indicated by the first information is the total time for completing the switch switching process and the power switching process. In the embodiments of the present application, the first information may indicate the interval time required for the antenna switching process in an explicit manner or in an implicit manner.
[0042] Optionally, the uplink transmission power requirement is determined by the uplink power control sent by the network-side device; and / or, the uplink peak-to-average power ratio requirement is determined by parameters such as the adjustment method of the uplink scheduling sent by the network-side device.
[0043] Step 32: The terminal receives the uplink transmission scheduling information sent by the network-side device.
[0044] The uplink transmission scheduling information is used to schedule the uplink transmission of the terminal, that is, the uplink transmission scheduling resources for the terminal, or is referred to as scheduling uplink transmission resources for the terminal. The uplink transmission includes but is not limited to: Physical Random Access Channel (PRACH), Physical Uplink Shared Channel (PUSCH) transmission, Physical Uplink Control Channel (PUSCH) transmission, Sounding Reference Signal (SRS) transmission, etc. The uplink transmission scheduling information may schedule the uplink transmission resources on different antennas for the terminal, or schedule the uplink transmission resources on the same antenna.
[0045] Step 33: When the uplink transmission resources scheduled by the uplink transmission scheduling information meet the interval time requirement indicated by the first information, the terminal performs uplink transmission according to the uplink transmission scheduling information.
[0046] If the uplink transmission resources scheduled by the uplink transmission scheduling information are on the same antenna, Figure 1For example, the scheduling terminal transmits PUSCH / PUCCH and SRS on antenna x. When the transmission powers of PUSCH / PUCCH and SRS are different, the first information can also be used to indicate the interval time required for the power switching process between different uplink transmissions, such as the time required to switch from the PUSCH / PUCCH transmission power to the SRS transmission power. Then, if the interval time requirement indicated by the first information is satisfied between the PUSCH / PUCCH transmission and the SRS transmission scheduled by the uplink transmission scheduling information, PUSCH / PUCCH and SRS are transmitted according to the uplink transmission scheduling information.
[0047] If the uplink transmission scheduling information schedules uplink transmission resources on different antennas, taking Figure 1 For example, the scheduling terminal transmits PUSCH / PUCCH on antenna y and SRS on antenna x. Then, if the interval time requirement indicated by the first information is satisfied between the PUSCH / PUCCH transmission and the SRS transmission scheduled by the uplink transmission scheduling information, PUSCH / PUCCH and SRS are transmitted according to the uplink transmission scheduling information.
[0048] It should be noted that the above-described scenario of first transmitting PUSCH / PUCCH and then transmitting SRS is only an exemplary illustration, and the scenario of first transmitting SRS and then transmitting PUSCH / PUCCH can also be adopted in the transmission scheme of the embodiments of the present application.
[0049] In some embodiments of the present application, the first information may include a target capability level, where the target capability level is one of multiple capability levels, and each capability level corresponds to its own interval time. Optionally, the first information may be terminal capability information, and the terminal carries the target capability level through the terminal capability information and reports the interval time required for the antenna switching process to the network-side device.
[0050] In some embodiments of the present application, the above-mentioned target capability level may also be referred to as a target scheduling level, and the target scheduling level is used to assist the network-side device in performing uplink transmission scheduling. Among them, the target scheduling level is one of multiple scheduling levels, and each scheduling level corresponds to its own interval time. Optionally, the first information may be terminal auxiliary information, and the terminal carries the target scheduling level through the terminal auxiliary information and reports the interval time required for the antenna switching process to the network-side device. It should be noted that the capability level and the scheduling level can be interchanged in some scenarios. The embodiments of the present application only use the capability level as an exemplary illustration, and the implementation manner of the scheduling level can also adopt the implementation manner of the capability level.
[0051] Among them, the unit of the interval time corresponding to the above ability level can be milliseconds (ms), time slots (slot), symbols (symbol), etc. That is to say, the interval time corresponding to the above ability level can include: 0, 1 or more ms / slots / symbols.
[0052] Furthermore, the interval time corresponding to each of the above multiple ability levels is related to the subcarrier spacing (SCS). Taking symbols as an example, under different SCSs, the number of symbols included in the interval time corresponding to an ability level may be different.
[0053] The system can support multiple ability levels, and the interval times corresponding to different ability levels are not exactly the same. In the embodiments of this application, two ability levels are taken as an example for illustrative purposes. The multiple ability levels include a first ability level and a second ability level, and the interval time corresponding to the first ability level is less than the interval time corresponding to the second ability level. Taking the time domain symbol as the unit of the interval time as an example, the interval time corresponding to the first ability level includes 0 or 1 time domain symbol, and the interval time corresponding to the second ability level includes 1 or more time domain symbols. For example, the UE feeds back the first information to the base station. The first information can be UE capabilities or UE assistance information, and the first information indicates the delay ability level when the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH. The delay ability is divided into ability level 1 and ability level 2, and the time delay required for ability level 1 is less than that for ability level 2. The time delay can be related to the SCS, and the time delay is inconsistent under different SCSs. Taking the time delay at the OFDM symbol level as an example, the time delay can include one or more OFDM symbols, and the time delay does not exceed 5 OFDM symbols. Among them, the OFDM symbol includes CP-OFDM and DFD-S-OFDM.
[0054] The above introduces the implementation method of the first information. The above method is applicable to a single-carrier scenario or a scenario without considering the impact of carriers. Next, the embodiments of this application will further introduce the implementation method of the first information under multi-carriers.
[0055] In the Carrier Aggregation (CA) or Dual-Connectivity (DC) working mode, multiple ability levels respectively correspond to the interval times on the CA frequency band combination or the DC frequency band combination. Multiple ability levels respectively correspond to the interval time on a CA frequency band combination or a DC frequency band combination. In addition, the multiple ability levels corresponding to different CA frequency band combinations or different DC frequency band combinations can also be different.
[0056] Optionally, the interval time on the CA frequency band combination or the DC frequency band combination is related to the SCS corresponding to the CA frequency band combination or the DC frequency band combination. Among them, the SCS on different carriers may be different, and the interval time on a certain CA frequency band combination or DC frequency band combination is determined based on the minimum or maximum SCS within the frequency band combination.
[0057] Since the SCS on different carriers may be different, in addition to considering the processing time of antenna switching, the interval time required for the antenna switching process indicated by the above first information also needs to consider the alignment problem of different carriers. Therefore, the interval time on the CA frequency band combination or the DC frequency band combination may include one or more time slots.
[0058] The above step 33 introduces the processing method when the uplink transmission resources scheduled by the uplink transmission scheduling information meet the interval time requirements indicated by the first information. Next, the embodiments of the present application will further introduce the processing method of the terminal when the uplink transmission resources scheduled by the uplink transmission scheduling information do not meet the interval time requirements indicated by the first information.
[0059] In some embodiments of the present application, when the uplink transmission resources scheduled by the uplink transmission scheduling information do not meet the interval time requirements indicated by the first information, the terminal does not respond to the transmission indication on the first resource in the uplink transmission resources, and the first resource is the resource that does not meet the interval time requirements indicated by the first information. Since the above interval time affects scheduling, the above interval time can be regarded as a scheduling restriction on the uplink and downlink of the UE, that is, within the interval time range, the UE does not need to accept any relevant PDCCH / PDSCH / PUCCH / PUSCH transmission requirements. In other words, if the network side device makes corresponding PDCCH / PDSCH / PUCCH / PUSCH transmission requirements for the UE within the time of symbols including the interval time through scheduling or configuration, the UE can choose not to respond to the scheduling. It should be noted that this method can also be applied to the same antenna transmission scenario. If the network side device makes corresponding PDCCH / PDSCH / PUCCH / PUSCH transmission requirements for the UE within the time of symbols including the power switching interval time through scheduling or configuration, the UE can also choose not to respond to the scheduling. It should be noted that in the CA or DC scenario, when the scheduling information sent by the base station does not meet the interval time requirements indicated by the first information, the terminal does not accept not only uplink scheduling but also downlink scheduling.
[0060] Optionally, when the uplink transmission includes at least SRS and at least one of PUSCH or PUCCH or PRACH, and when at least one of the following conditions is met, the UE preferentially chooses to abandon SRS transmission:
[0061] a. Corresponding to PUSCH / PUCCH transmissions with a higher priority, i.e., the priority sequence number corresponding to the PUSCH / PUCCH transmission is greater than or equal to 1;
[0062] b. Corresponding to uplink transmissions including any one of the following:
[0063] a) ACK-NACK feedback of the HARQ process
[0064] b) Scheduling request
[0065] c) Channel Rank indication
[0066] d) SSB or CSI-RS resource sequence number indication
[0067] e) Uplink physical layer random access channel
[0068] c. If the SRS is a periodically or semi-statically transmitted SRS, but the PUSCH or PUCCH contains aperiodic CSI feedback information.
[0069] Optionally, when none of the above conditions are met, the UE chooses to abandon PUSCH or PUCCH transmission.
[0070] Alternatively, when the uplink transmission resources scheduled by the uplink transmission scheduling information do not meet the interval time requirements indicated by the first information, the terminal performs uplink transmission according to the uplink transmission scheduling information. This scenario can be regarded as the network-side device can ignore the first information and independently schedule the terminal, and the terminal performs corresponding transmission according to the scheduling. In an alternative solution, the network-side device, through scheduling or configuration, requires the UE to perform corresponding PDCCH / PDSCH / PUCCH / PUSCH transmissions within the time of the symbols included in the interval time. The terminal needs to perform corresponding transmissions within this interval time according to the scheduling, but can ignore the power requirements of the network-side device.
[0071] The uplink transmission in the embodiments of this application includes one of PUSCH transmission, PUCCH transmission, and SRS transmission. When the uplink transmission corresponding to the antenna handover process includes SRS transmission, the transmit antenna of the SRS transmission is different from the antenna port of the transmit antenna of the PUSCH transmission or the PUCCH transmission. The interval time required between the SRS transmission and the PUSCH transmission or the PUCCH transmission is on 0 or 1 or more OFDM symbols before or after the SRS transmission. When the uplink transmission corresponding to the antenna handover process includes two SRS transmissions, the antenna ports of the transmit antennas of the two SRS transmissions are different, and the required interval between the two SRS transmissions is 0 or 1 or more OFDM symbols.
[0072] Optionally, the first information can also be used to indicate the maximum time interval during which the UE can be scheduled for uplink before and after the SRS when the UE needs to perform antenna switching for SRS transmission; or, the maximum value of the UE power switching time before and after the SRS when the UE needs to perform antenna switching for SRS transmission.
[0073] Taking the first information as the capability information as an example, the uplink transmission method of the embodiments of the present application includes: The UE sends capability information to the network, and this capability information indicates the difference in delay capability when the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH. The network side device configures SRS and PUSCH / PUCCH resources for the UE based on the UE's capability. When the reported delay is small, the interval between the SRS and PUSCH / PUCCH resources configured by the network side device for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of the CP or 0 OFDM symbols; if the reported delay is large, the configured interval is greater than 1 predefined length, such as an interval of at least one OFDM symbol. In particular, the above delay represents the uplink and downlink scheduling restriction for the UE, that is, within the delay range, the UE does not need to accept any relevant PDCCH / PDSCH / PUCCH / PUSCH transmission requirements. In other words, if the network side device makes a corresponding PDCCH / PDSCH / PUCCH / PUSCH transmission requirement for the UE within the time of the symbols included in the delay through scheduling or configuration, the UE can choose not to respond.
[0074] Taking the first information as the auxiliary information as an example, the uplink transmission method of the embodiments of the present application includes: The UE sends auxiliary information to the network side device, and this auxiliary information indicates the minimum value of the interval between the corresponding OFDM symbols when the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH. The network side device configures SRS and PUSCH / PUCCH resources for the UE based on the UE's auxiliary information. When the minimum interval required by the reported auxiliary information of the UE is small, the interval between the SRS and PUSCH / PUCCH resources configured by the network side device for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of the CP or 0 OFDM symbols; if the minimum interval required by the reported auxiliary information is large, the configured interval by the network is greater than 1 predefined length, such as an interval of at least one OFDM symbol. In particular, the above delay represents the uplink and downlink scheduling restriction for the UE, that is, within the delay range, the UE does not need to accept any relevant PDCCH / PDSCH / PUCCH / PUSCH transmission requirements. In other words, if the network side device makes a corresponding PDCCH / PDSCH / PUCCH / PUSCH transmission requirement for the UE within the time of the symbols included in the delay through scheduling or configuration, the UE can choose not to respond.
[0075] In the uplink transmission method according to the embodiment of the present application, the terminal sends first information to the network-side device, where the first information is used to indicate the interval time required for the antenna switching process; receives the uplink transmission scheduling information sent by the network-side device; and when the uplink transmission resources scheduled by the uplink transmission scheduling information meet the interval time requirement indicated by the first information, performs uplink transmission according to the uplink transmission scheduling information. In this way, when the network-side device schedules resources for the terminal, it can avoid the interval time required for antenna switching, so as to avoid the loss of transmission performance caused by the power not meeting the standard during the antenna switching time interval.
[0076] It should be noted that for the uplink transmission method provided by the embodiment of the present application, the execution subject may be an uplink transmission device, or a control module in the uplink transmission device for executing the uplink transmission method. In the embodiment of the present application, the uplink transmission method is executed by the uplink transmission device as an example to illustrate the uplink transmission device provided by the embodiment of the present application.

[0096] In the uplink transmission device according to the embodiment of the present application, by sending first information to a network-side device, the first information is used to indicate the interval time required for the antenna switching process; receiving uplink transmission scheduling information sent by the network-side device; when the uplink transmission resources scheduled by the uplink transmission scheduling information meet the interval time requirement indicated by the first information, performing uplink transmission according to the uplink transmission scheduling information, so that the network-side device can avoid the interval time required for antenna switching when scheduling resources for the terminal, so as to avoid the transmission performance loss caused by insufficient power during the antenna switching time interval for the terminal.
[0097] The uplink transmission device in the embodiment of the present application may be a device, a device with an operating system or an electronic device, or a component, an integrated circuit, or a chip in a terminal. The device or the electronic device may be a mobile terminal or a non-mobile terminal. Exemplarily, the mobile terminal may include, but is not limited to, the types of the terminal 11 listed above, and the non-mobile terminal may be a server, a Network Attached Storage (NAS), a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc., which are not specifically limited in the embodiment of the present application.
[0098] The uplink transmission device provided by the embodiment of the present application can implement Figure 3 each process implemented by the method embodiment, and achieve the same technical effect. To avoid repetition, it will not be elaborated here.
[0099] The terminal-side uplink transmission method and device according to the embodiment of the present application are introduced above. Next, the uplink transmission method and device of the network-side device will be further introduced with reference to the accompanying drawings.
[0100] As Figure 5 shown, the embodiment of the present application provides an uplink transmission method, including but not limited to the following steps:
[0101] Step 51: The network-side device receives the first information sent by the terminal, and the first information is used to indicate the interval time required for the antenna switching process.
[0102] Among them, the interval time can also be referred to as delay. The interval time required for the antenna switching process indicated by the first information is the maximum of the interval times required for the antenna switching process under different uplink transmission power requirements and / or peak-to-average ratio requirements. The interval time required for the antenna switching process includes the switch switching and power switching interval times. The interval time required for the antenna switching process indicated by the first information is the total time for completing the switch switching process and the power switching process. In the embodiments of the present application, the first information can indicate the interval time required for the antenna switching process in an explicit manner or in an implicit manner.
[0103] Step 52: The network-side device sends uplink transmission scheduling information to the terminal according to the first information, and the uplink transmission scheduling information is used to schedule uplink transmission resources.
[0104] The uplink transmission in the embodiments of the present application includes one of PRACH, PUSCH transmission, PUCCH transmission, and SRS transmission.
[0105] Taking the first information as the capability information as an example, the uplink transmission method in the embodiments of the present application includes: The UE sends capability information to the network. When the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH, there are differences in the delay capabilities. Based on the UE capability, the network-side device configures SRS and PUSCH / PUCCH resources for the UE. When the reported delay is small, the interval between the SRS and PUSCH / PUCCH resources configured by the network-side device for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of the CP or 0 OFDM symbols; if the reported delay is large, the configured interval is greater than 1 predefined length, such as an interval of at least one OFDM symbol.
[0106] Taking the first information as the auxiliary information as an example, the uplink transmission method in the embodiments of the present application includes: The UE sends auxiliary information to the network-side device. When the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH, the minimum value of the interval between the corresponding OFDM symbols is indicated. Based on the auxiliary information of the UE, the network-side device configures SRS and PUSCH / PUCCH resources for the UE. When the minimum interval required by the reported auxiliary information is small, the interval between the SRS and PUSCH / PUCCH resources configured by the network-side device for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of the CP or 0 OFDM symbols; if the minimum interval required by the reported auxiliary information is large, the configured interval by the network is greater than 1 predefined length, such as an interval of at least one OFDM symbol.
[0107] Similar to the method embodiments on the terminal side, in some embodiments of the present application, the first information may include a target capability level, where the target capability level is one of multiple capability levels, and each capability level corresponds to its own interval time. Optionally, the first information may be terminal capability information, and the terminal carries the target capability level through the terminal capability information and reports the interval time required for the antenna switching process to the network-side device.
[0108] The above-mentioned target capability level may also be referred to as a target scheduling level, and the target scheduling level is used to assist the network-side device in performing uplink transmission scheduling. Among them, the target scheduling level is one of multiple scheduling levels, and each scheduling level corresponds to its own interval time. Optionally, the first information may be terminal assistance information, and the terminal carries the target scheduling level through the terminal assistance information and reports the interval time required for the antenna switching process to the network-side device. It should be noted that the capability level and the scheduling level can be interchanged in some scenarios. In the embodiments of the present application, only the capability level is used as an exemplary illustration, and the implementation method of the scheduling level can also adopt the implementation method of the capability level.
[0109] Among them, the unit of the interval time corresponding to the above-mentioned capability level may be milliseconds (ms), time slots (slot), symbols (symbol), etc. The interval time corresponding to the above-mentioned capability level may include: 0, 1, or multiple ms / slots / symbols.
[0110] Furthermore, the interval time corresponding to each of the above-mentioned multiple capability levels is related to the subcarrier spacing SCS. Taking symbols as an example, under different SCSs, the number of symbols included in the interval time corresponding to a capability level may be different.
[0111] Similar to the method embodiments on the terminal side, the system can support multiple capability levels, and the interval times corresponding to different capability levels are not exactly the same. In the embodiments of the present application, two capability levels are taken as an example for illustrative purposes. The multiple capability levels include a first capability level and a second capability level, and the interval time corresponding to the first capability level is less than the interval time corresponding to the second capability level. Taking the time domain symbol as the unit of the interval time, the interval time corresponding to the first capability level includes 0 or 1 time domain symbol, and the interval time corresponding to the second capability level includes 1 or more time domain symbols. For example, the UE feeds back the first information to the base station. The first information can be UE capability or UE assistance information, and the first information indicates the delay capability level when the antenna for the UE to send SRS is different from the antenna for PUSCH or PUCCH. The delay capability is divided into capability level 1 and capability level 2, and the time delay required for capability level 1 is less than that for capability level 2. The time delay can be related to SCS, and the time delay is inconsistent under different SCSs. Taking the time delay at the OFDM symbol level as an example, the time delay can include one or more OFDM symbols, and the time delay does not exceed 5 OFDM symbols. Among them, the OFDM symbol includes CP-OFDM and DFT-S-OFDM.
[0112] The implementation manner of the first information is introduced above, and the above manner is applicable to a single-carrier scenario or a scenario without considering the influence of carriers. Next, the embodiments of the present application will further introduce the implementation manner of the first information under multi-carriers.
[0113] In the carrier aggregation CA or dual connection DC working mode, the multiple capability levels respectively correspond to the interval times on the CA frequency band combination or the DC frequency band combination. The multiple capability levels respectively correspond to the interval time on a CA frequency band combination or a DC frequency band combination. In addition, the multiple capability levels corresponding to different CA frequency band combinations or different DC frequency band combinations can also be different.
[0114] Optionally, the interval time on the CA frequency band combination or the DC frequency band combination is related to the SCS corresponding to the CA frequency band combination or the DC frequency band combination. Among them, the SCSs on different carriers may be different, and the interval time on a certain CA frequency band combination or DC frequency band combination is determined based on the minimum or maximum SCS within the frequency band combination.
[0115] Since the SCSs on different carriers may be different, for the interval time required for the antenna switching process indicated by the above first information, in addition to considering the processing time of the antenna switching, the alignment problem of different carriers also needs to be considered. Therefore, the interval time on the CA frequency band combination or the DC frequency band combination can include one or more time slots.
[0116] In the case where the uplink transmission corresponding to the antenna switching process includes SRS transmission, the transmitting antenna of the SRS transmission is different from the antenna port of the transmitting antenna of the PUSCH transmission or the PUCCH transmission, and the required interval time between the SRS transmission and the PUSCH transmission or the PUCCH transmission is on 0 or 1 or more OFDM symbols before or after the SRS transmission. In the case where the uplink transmission corresponding to the antenna switching process includes two SRS transmissions, the antenna ports of the transmitting antennas of the two SRS transmissions are different, and the required interval between the two SRS transmissions is 0 or 1 or more OFDM symbols.
[0117] Optionally, the first information may also be used to indicate the maximum time interval during which the UE can be scheduled for uplink before and after the SRS when the UE needs to perform antenna switching for transmitting the SRS; or, the maximum value of the UE power switching time before and after the SRS when the UE needs to perform antenna switching for transmitting the SRS.
[0118] In the uplink transmission method according to the embodiment of the present application, the network-side device receives the first information sent by the terminal, and the first information is used to indicate the interval time required for the antenna switching process; the network-side device sends uplink transmission scheduling information to the terminal according to the first information, and the uplink transmission scheduling information is used to schedule uplink transmission resources. In this way, considering the first information when scheduling resources for the terminal to avoid the interval time required for antenna switching can avoid the loss of transmission performance caused by insufficient power of the terminal during the antenna switching time interval.
