The technologies described can be applied to both the systems and the radio technologies mentioned above as well as to other systems and radio technologies. The following describes a New Radio (NR) system for example purposes, and NR terms are used in most of the following descriptions. These technologies can also be applied to applications other than an NR system application, such as a 6th Generation (6G) communication system.
First, related concepts in the embodiments of this application are described.
In the R16, a mechanism of uplink transmit channel switching (UL Tx switching) is introduced. That is, one terminal can perform sending on a maximum of two transmit channels Tx at the same time, one carrier supports one uplink transmit channel (for example, a carrier 1), and another carrier supports two transmit channels (for example, a carrier 2), where the carrier 1 and the carrier 2 are on different bands, and switching between two modes is supported through Tx switching. Mode 1: Uplink dual-stream transmission is performed on the carrier 2. Mode 2: Single-stream transmission is performed on the carrier 1 and/or the carrier 2.
Based on whether uplink transmission is supported on the carrier 1 and the carrier 2 at the same time, there is an option 1 (a network configures an upper-layer parameter uplinkTxSwitchingOption-r16 as switchedUL, indicating that uplink transmission cannot be performed on the carrier 1 and the carrier 2 at the same time) and an option 2 (a network configures an upper-layer parameter uplinkTxSwitchingOption-r16 as dualUL, indicating that uplink transmission can be performed on the carrier 1 and the carrier 2 at the same time).
The UL Tx switching supported by the R16 is as follows:
First, it should be noted that 1T+1T represents that the carrier 1 has 1Tx and the carrier 2 has 1Tx; and 1P+0P represents that the carrier 1 has one antenna port for sending, and the carrier 2 has no antenna port for sending (that is, no data is sent). It may be considered that 1Tx supports a maximum of one antenna port for sending. In
The terminal reports whether the option 1 or the option 2 is supported or both are supported through a parameter uplinkTxSwitching-OptionSupport, reports a period required for UL Tx switching through a parameter uplinkTxSwitchingPeriod, and reports a band that supports downlink interruption through a parameter uplinkTxSwitching-DL-Interruption.
A network upper-layer parameter uplinkTxSwitchingOption is used to configure the terminal to support the option 1 or the option 2, uplinkTxSwitching is used to configure whether the serving cell is used for UL Tx switching, and uplinkTxSwitchingPeriodLocation is used to configure a cell associated with a switching period (for example, a switching period, a start location, and an end location) and is used to determine a location of the switching period. As shown in
A downlink interruption time length is related to a switching time length, as shown in Table 1 below. A start location of a downlink interruption time is the first OFDM symbol that overlaps a start moment of a switching period.
Further, in the R17 phase, inter-CA and SUL switching is extended. First, 2Tx-2Tx switching is supported, that is, switching between two Txs is supported on two carriers. Further, Tx switching between one carrier on a band A and two consecutive carriers on a band B (sending may be performed on the two carriers by using a same Tx) is further supported. In addition, two new Radio Resource Control (RRC) parameters are introduced, where one parameter is used to indicate a 1Tx−2Tx switching mode or a 2Tx−2Tx switching mode, so as to determine whether a 1Tx−2Tx or 2Tx−2Tx switching parameter is used; and when a Tx state is not unique after UL Tx switching, one parameter is used to indicate that the Tx state is 1Tx+1Tx or the Tx state is 0Tx+2Tx. For example, when uplinkTxSwitchingPeriod2T2T-r17 is configured, the terminal supports 2Tx−2Tx switching, and the configured switching period is determined by using uplinkTxSwitchingPeriod2T2T-r17. If the parameter is not configured (that is, a value of the parameter is null), the configured switching period is determined by using uplinkTxSwitchingPeriod-r16. It should be noted that switching modes supported by 1Tx−2Tx and 2Tx−2Tx are partially overlapping, that is, some switching modes may belong to 1Tx−2Tx and also 2Tx−2Tx, and a difference is that switching parameters of different modes are different.
Currently, the terminal may perform uplink sending on a maximum of two transmit channels at the same time, and the two transmit channels support switching between only two uplink UL bands. In the future, the terminal may support more than two uplink and/or sidelink bands.
With reference to the accompanying drawings, the following describes in detail the parameter determining method provided in the embodiments of this application by using some embodiments and application scenarios thereof.
In some embodiments, a configuration resource of the terminal includes N physical units, where the physical unit is, for example, a carrier, a band, a BWP, or a resource pool. The terminal performs transmission on at least one of N (N>2) physical units, where the transmission is transmission based on at least one of M transmit channels, or the transmission is transmission based on at least one of M transmit channels on a physical unit after transmit channel switching, where M is less than or equal to N. The terminal determines, based on the target information, the target parameter used for transmission or switching, where a physical unit supported by a transmit channel in the target information means that data of the physical unit may be transmitted by using the transmit channel. For example, if Tx1 supports {band 1, band 2, and band 3}, it indicates that data of the band 1, the band 2, and the band 3 may be transmitted by using the transmit channel Tx1, and if Tx2 supports {band 1, band 2}, it indicates that data of the band 1 and the band 2 may be transmitted by using the transmit channel Tx2. A transmit channel supported by a physical unit is a transmit channel that can be used when the physical unit sends data. For example, if a physical unit 1 supports Tx1, it indicates that the physical unit 1 can send data by using the transmit channel Tx1, and if a physical unit 2 supports Tx1 and Tx2, it indicates that the physical unit 2 can send data by using the transmit channels Tx1 and Tx2.
A physical unit in which a transmit channel is located is a physical unit including or using the transmit channel, a physical unit including the transmit channel represents a physical unit that has the transmit channel, and a physical unit using the transmit channel represents a physical unit that has the transmit channel and that uses the transmit channel to send data.
The release of the terminal and/or the network side device is, for example, a terminal and/or a network side device that support the R16, R17, and/or R18 protocols.
The terminal may determine, based on the target information and a current state of the terminal, for example, capability information of the terminal and a network state in which the terminal is located, the target parameter used for transmission or transmit channel switching.
It should be noted that the N physical units may be configured, for example, by using different types of physical units. For example, the terminal is configured with three carriers, and the three carriers are on two bands. Therefore, the N physical units may be two bands.
According to the method in this embodiment, in a case that a terminal performs transmission on at least one of two physical units, the transmission may be based on at least one of M transmit channels, or the transmission may be based on at least one of M transmit channels on a physical unit after transmit channel switching. The terminal may determine, based on target information, a target parameter used for transmission or switching, so that a scheme of determining, based on the target information, the target parameter used for transmission or switching is implemented in a scenario in which transmission or transmit channel switching on more than two physical units is supported.
In some embodiments, the target information is determined based on the capability information of the terminal and/or is configured by the network side device.
In some embodiments, the physical unit includes at least one of the following: a carrier, a bandwidth part BWP, a band, or a resource pool.
In some embodiments, step 101 may be implemented in the following manner:
The terminal determines the target parameter based on a correspondence between the target information and a parameter and based on the target information corresponding to the terminal.
In some embodiments, the terminal determines the target parameter based on the correspondence between the target information and the parameter and based on a current state of the terminal, that is, the target information corresponding to the terminal.
In some embodiments, the correspondence is determined based on the capability information of the terminal, configured by the network side device, and/or specified in a protocol.
For example, the terminal reports a supported transmission or switching type and other capability information, and the transmission or switching type may be in a one-to-one correspondence with the target parameter. The terminal determines the target parameter based on actual transmission or Tx switching.
In some embodiments, in a case that the correspondence is configured by the network side device, the correspondence is configured by the network side device based on the capability information reported by the terminal.
For example, the network side device supplements content of the correspondence based on the capability information reported by the terminal, or the network side device directly configures the correspondence based on the capability information of the terminal.
In the foregoing implementation, the terminal may directly determine the corresponding target parameter based on actual transmission or switching and the correspondence, so as to quickly determine the target parameter. Therefore, processing complexity of the terminal is reduced, and a processing delay of transmission or switching is relatively small.
In some embodiments, a quantity of physical units on which at least one of the M transmit channels is located meets at least one of the following:
In some embodiments, the target parameter is related to a quantity of physical units in which Tx is located, and the quantity of physical units in which Tx is located meets at least one of the foregoing items. For example, if a quantity of physical units including Tx before transmit channel Tx switching is N1, and a quantity of physical units including Tx after transmit channel Tx switching is N2, a sum of the quantity of physical units including Tx before transmit channel Tx switching and a quantity of physical units including Tx after a transmission change, a scheduling change, or Tx switching is equal to N1+N2, and a total quantity of physical units including Tx before and after transmit channel Tx switching is less than or equal to N1+N2, because there may be duplicate physical units in the physical unit including Tx before transmit channel Tx switching and the physical units including Tx after transmit channel Tx switching.
For example, if physical units including Tx before Tx switching are {band A, band B} and a quantity of physical units including Tx before Tx switching is 2, and physical units including Tx after Tx switching are {band A, band C} and a quantity of physical units including Tx after Tx switching is 2, a total quantity of physical units including transmit channels before and after switching is 3, and a sum of the quantity of physical units including Tx before Tx switching and the quantity of physical units including Tx after Tx switching is 4.

The first threshold to the eighth threshold may be the same or different. In some embodiments, the first threshold to the fourth threshold may respectively have one or more values, and may be applicable to different scenarios.
In some embodiments, the target parameter is related to an index of a physical unit in which Tx is located, and an index of the physical unit on which the at least one of the M transmit channels is located meets at least one of the following:
For example, if physical units including Tx before Tx switching are {band A, band B} and indexes are {1, 2}, and physical units including Tx after switching are {band A, band C} and indexes are {1, 3}, there is the same index 1.
In some embodiments, the target parameter is related to a quantity of transmit channels included or used by a physical unit, and a quantity of transmit channels included or used by at least one of the N physical units meets at least one of the following:
The ninth threshold to the fourteenth threshold may be determined by the terminal, configured by the network side device, or predetermined in a protocol.

The foregoing physical unit may be represented as any physical unit or a preset specific physical unit.
The foregoing transmit channel switching may occur in a case that a transmission situation of the terminal changes (or a scheduling situation changes), and that a transmission situation changes or a scheduling situation changes means that, for example, a transmission situation or a scheduling situation of a physical unit and/or a transmit channel changes.
In some embodiments, the target parameter is related to a quantity (for example, a maximum quantity) of physical units supported by Tx, and a quantity of physical units supported by at least one of the M transmit channels meets:
In some embodiments, the at least one transmit channel may be any transmit channel or a preset transmit channel, for example, may be determined by the terminal, configured by the network side device, or predetermined in a protocol.

The index of the physical unit supported by the at least one transmit channel may be a preset index, or belongs to a preset range, for example, the first index set, where the first index set may be determined by the terminal, configured by the network side device, or predetermined in a protocol.
In some embodiments, the target parameter is related to a quantity (for example, a maximum quantity) of Tx/antenna ports/MIMO layers supported by a physical unit, and the quantity of at least one item of transmit channels, antenna ports, or MIMO layers supported by the at least one of the N physical units meets:

The sixteenth threshold to the eighteenth threshold may be determined by the terminal, configured by the network side device, or predetermined in a protocol.

In some embodiments, the foregoing parameter is determined based on the capability information of the terminal, or is configured by the network side device, or is configured by the network side device based on the capability information of the terminal.
For example, the terminal reports, based on a band pair (that is, a fine granularity), a parameter used for transmission or Tx switching, and the network side device configures, based on a band list or a band combination (that is, a coarse granularity), a parameter used for transmission or Tx switching. The band list includes three bands. The terminal reports, based on each band pair between the three bands, parameters used for transmission or Tx switching, and the network side device configures the most loose and/or strictest parameter in the parameters, for example, maximum/minimum switching duration.
In some embodiments, the downlink interruption time information is related to at least one of the following:
In some embodiments, a start location of a downlink interruption time is related to a start location of the switching period, and a start slot of the downlink interruption time is the first slot that overlaps the start location of the switching period.

In some embodiments, for all physical units configured for the terminal, physical units with downlink interruption in a switching process are the same.
For each target unit (for example, a physical unit pair) configured for the terminal, physical units with downlink interruption in a switching process may be separately set, and may be the same or different.
In some embodiments, at least one target unit corresponding to the terminal has same switching period information; or

In some embodiments, at least one target unit corresponding to the terminal has a same physical unit associated with switching period information; or
In some embodiments, for all physical units configured for the terminal, physical units associated with switching period information are the same.
For each target unit (for example, a physical unit pair) configured for the terminal, physical units associated with switching period information are separately set, for example, may be the same or different.
For example, in the following several cases, different target parameters are separately configured.
When M=2 and N=3, the terminal is configured with three uplink carriers (carrier 1, carrier 2, carrier 3), which are respectively on three bands (band A, band B, band C).
Example 1: As shown in Table 2 and Table 3, Table 2 may represent switching from Case 2 to Case 1 or switching from Case 1 to Case 2, and Table 3 may represent switching from Case 5 to Case 3 or switching from Case 3 to Case 5. A quantity of bands including Tx before Tx switching is equal to 2, and a quantity of bands including Tx after Tx switching is equal to 1. A maximum of one Tx is on one of the band A and the band B, and the other band supports two Txs.
Example 2: As shown in Table 4, Table 4 may represent switching between Case 2, Case 3, and Case 4, for example, switching from Case 2 to Case 3 or switching from Case 3 to Case 4. A quantity of bands including Tx before/after Tx switching is equal to 1, and indexes are different, and another switching case is similar. A quantity of Txs on one band is 2.

A quantity of Txs on the first two bands is 1, and the third band supports two Txs. Table 6 may represent switching from Case 1 to Case 4 or switching from Case 4 to Case 1.
Example 5: As shown in Table 7, for example, in switching from Case 1 to Case 6, a quantity of bands including Tx before/after Tx switching is equal to 2, and indexes are different. A quantity of Txs on one band is 1. Table 7 may represent switching from Case 1 to Case 6 or switching from Case 6 to Case 1.
The terminal determines a switching case (for example, switching between which two cases), to determine the target parameter used for switching.
For example, if the terminal reports/the network side device configures that a switching period of Case 4 in the foregoing example is 210 us, and a physical unit associated with the switching period is configured as the band C, the downlink interruption time (DL interruption time) is the first slot from the switching period.
