According to the first indication information in the sixth embodiment, after the terminal device determines to divide the time-frequency resources into K parts in the time domain, the time-frequency resources divided into K parts in the time domain may be repeatedly received in N time slots. Accordingly, in this case, the network device may repeatedly transmit the time-frequency resources divided into K parts in the time domain over N slots. Wherein K is the transmission times of the PDSCH in a time slot; the number of PDSCH transmissions K within one slot may be indicated by a dedicated indication field in one DCI or determined by a specified parameter configuration or indication, e.g., the number of TCI states indicated by one DCI.

In the fifth and sixth embodiments, when the number of PDSCH transmissions K in one slot is indicated by a dedicated indication field in one DCI, the indication field for indicating the fifth value is the same as or different from the dedicated indication field; wherein, in the case that the indication field indicating the fifth value is the same as the dedicated indication field, the first indication information may indicate K and N on the same indication field by means of joint coding. For example: multiple combinations of K and N are configured by RRC, and one combination is indicated by a DCI to be used as the value of K and N.

Under the condition that the time-frequency resources are determined to be divided in the time domain, time-domain symbols contained in the time-frequency resources can also be configured. The specific configuration is as in the following examples. In the following embodiments, the time domain symbols are all Orthogonal Frequency Division Multiplexing (OFDM) symbols.

EXAMPLE seven

Under the condition that the time-frequency resource is determined to be divided in the time domain, if the time-frequency resource comprises L time-domain symbols, the terminal equipment determines to divide the L time-domain symbols into K parts under the condition that the L time-domain symbols do not comprise uplink symbols; and under the condition that the time-frequency resource contains the uplink symbols which are determined to be sent, determining to divide the available downlink symbols except the uplink symbols in the L time-domain symbols into K parts.

Wherein K is the transmission times of the PDSCH in a time slot; the number of PDSCH transmissions K within one slot may be indicated by a dedicated indication field in one DCI or determined by a specified parameter configuration or indication, e.g., the number of TCI states indicated by one DCI.

In this embodiment, it is determined to divide L time domain symbols into K parts, and specifically, it is determined that each of the first K-1 parts includes M₁A down symbol, the Kth part containing L- (K-1) M₁A downlink symbol; m₁Is composed of

Upper round or lower round.

The available downlink symbols except the uplink symbols in the L time domain symbols are determined to be divided into K parts, specifically, the uplink symbols except the uplink symbols between the starting symbols of the L time domain symbols and the last symbol of the time slot to which the L time domain symbols belong are determinedAvailable front L₁Dividing each downlink symbol into K parts; the first K-1 part contains M₂A downlink symbol, the Kth part contains L₁-(K-1)*M₂A downlink symbol; wherein M is₂Is composed of

Upper or lower rounding of (L)₁The number of available downlink symbols and the minimum value in L or the number of downlink symbols except uplink symbols in L time domain symbols from the starting symbol of the L time domain symbols to the last symbol of the time slot to which the L time domain symbols belong; or, M₂Is composed of

Upper round or lower round.

After determining to divide the L time domain symbols into K parts or to divide the available downlink symbols other than the uplink symbols into K parts, the PDSCH of each time can be transmitted by using the divided time domain symbols, respectively.

Example eight

When a time-frequency resource configuration mode that one DCI schedules one or more PDSCH transmissions is determined according to first indication information, if one DCI schedules a plurality of PDSCH transmissions on a time domain, the L time domain symbols are used for transmitting the first PDSCH under the condition that no uplink symbol exists in a time slot to which the L time domain symbols belong, and other K-1 PDSCHs are sequentially transmitted by using the time domain symbols connected with the L time domain symbols; wherein, L is the number of time domain symbols required to be occupied by each PDSCH transmission.

Under the condition that at least one section of uplink symbols exist in the time slot to which the L time domain symbols belong, if the number of downlink symbols occupied before the downlink symbols are switched to the uplink symbols in one-time PDSCH transmission is less than L, the next section of downlink symbols in the time slot to which the L time domain symbols belong is continuously utilized to transmit the PDSCH until the number of downlink symbols occupied by the PDSCH transmission is equal to L or the last time domain symbol of the time slot to which the L time domain symbols belong is reached.

In the seventh and eighth embodiments, if one DCI indicates a plurality of TCI state numbers, it is determined that downlink symbols of each segment belonging to one PDSCH transmission correspond to the same TCI state; or, determining that each segment of downlink symbols respectively corresponds to each TCI state.

After determining that each downlink symbol belonging to one PDSCH transmission corresponds to the same TCI state, it is possible to transmit Transport Block (TB) information of one RV using each downlink symbol.

In the above embodiment, after it is determined that the L time domain symbols are divided into K, if the number of downlink symbols corresponding to the last PDSCH transmission is less than the preset threshold, it is determined that the last PDSCH transmission is not transmitted, or it is determined that the number of downlink symbols corresponding to the last PDSCH transmission belongs to the last PDSCH transmission.

For example, the preset threshold is 2, and assuming that the number of downlink symbols corresponding to the last PDSCH transmission is 1 (i.e., smaller than the preset threshold), it may be determined that the last PDSCH transmission is not transmitted, or it is determined that the number of downlink symbols corresponding to the last PDSCH transmission belongs to the last PDSCH transmission.

Example nine

After the Time-frequency resource configuration mode is determined to divide the Time-frequency resources into K parts in the Time domain, the HARQ-ACK codebook may be confirmed according to a pre-configured semi-static hybrid automatic repeat request, and it is determined that one HARQ-ACK message is fed back on a candidate PDSCH receiver opportunity corresponding to Time Domain Resource Allocation (TDRA) for K or K' times of PDSCH transmission. Wherein K' is the number of PDSCH transmissions in a finally determined one time slot.

As can be seen from the first to ninth embodiments, for the time-frequency resource indicated by one DCI, the terminal device may determine the time-frequency resource configuration mode for one or more times of PDSCH transmission scheduled by the one DCI according to the first indication information configured or indicated by the network device, so as to specify the time-frequency resource configuration mode for one or more times of PDSCH transmission scheduled by the one DCI in a multi-TRP transmission scenario.
