[0187] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0188] In order to improve uplink (UL) coverage and throughput, duplex enhancement (duplex enhancement) has been studied on subband full duplex (SBFD).

[0189] In some embodiments, a carrier component (CC) on a downlink (DL) or flexible (F) symbol is divided into multiple subbands (SBs) in the frequency domain. The multiple SBs include one UL subband and at least one (one or two) DL subbands. A base station can transmit DL signals on the DL subband and simultaneously receive UL signals on the UL subband. DL or F symbols can be configured in at least one of the following ways:

[0190] TDD-UL-DL-ConfigCommon configuration;

[0191] TDD-UL-DL-ConfigDedicated configuration;

[0192] TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated configurations; and

[0193] Downlink control information format 2-0 (DCI format 2-0) indication.

[0194] When a symbol includes both a DL subband and a UL subband in the frequency domain, it may be called an SBFD symbol.

[0195] In some embodiments, when a time slot includes at least one SBFD symbol among multiple symbols, the time slot may be called a SBFD time slot. Please refer to Figure 1b, time slot 0 is a DL time slot, time slots 1 to 3 are SBFD time slots, and time slot 4 is a UL time slot.

[0196] In some embodiments, when all the multiple symbols included in a time slot are SBFD symbols, the time slot may be called a SBFD time slot.

[0197] In some embodiments, a guard band (GB) may exist between the DL subband and the UL subband to reduce interference between DL signals in the DL subband and UL signals in the UL subband through frequency domain isolation.

[0198] In some embodiments, the PUSCH coverage performance can be enhanced and the latency can be reduced by using the physical uplink shared channel (PUSCH) repetition type B (PUSCH repetition type B). The symbol where the nominal repetition (nominal repetition) of the PUSCH repetition type B transmission is located is indicated by the downlink control information (DCI). The PUSCH repetition type B transmission can span time slots, that is, the PUSCH repetition type B is sent in multiple time slots. According to the DCI indication or RRC configuration, it is determined whether the symbol in the symbol where the PUSCH repetition type B transmission is located is an invalid symbol (invalid symbol) or a valid symbol (valid symbol). Among them, the invalid symbol cannot be used for UL transmission. According to the position of the valid symbol, the UE determines the symbol position of each PUSCH actual repetition (actual repetition) transmission.

[0199] In some embodiments, multiple repetition transmissions in PUSCH repetition type B can be transmitted in SBFD and non-SBFD symbols at the same time, but one repetition transmission can only be transmitted in SBFD symbols or non-SBFD symbols. The actual repetition division method of PUSCH has the following problem: one PUSCH actual repetition may include both SBFD and non-SBFD symbols.

[0200] In some embodiments, the following is the confirmation method of nominal repetition and actual repetition in PUSCH repetition type B:

[0201] In some embodiments, the starting time slot, starting symbol S, and continuous symbol duration L of the first nominal repetition are determined according to the DCI;

[0202] In some embodiments, the number of repetitions of the nominal reception is determined according to numberOfRepetitions-r16 configured by the RRC, and the symbol of each nominal reception is determined in combination with the DCI indication;

[0203] In some embodiments, after the terminal determines the invalid symbols in the time domain resources of each nominal repetition according to certain criteria, the other symbols can be considered as potential valid symbols. If the number of potentially valid symbols in the symbol where nominal repetition #1 is located is greater than 0, then nominal repetition #1 contains one or more actual repetitions. If the number of all potentially valid symbols in a row of nominal repetition #1 in a time slot is greater than 0, it can form an actual repetition. Unless the continuous symbol length L of the nominal repetition is 1, an actual repetition containing 1 symbol is not sent, for example, the 6th PUSCH actual repetition is not sent.

[0204] Please refer to Figure 1c for an illustration of nominal repetition and actual repetition. It should be noted that the terms "nominal repetition," "nominal copy," and "nominal repeated transmission" are interchangeable throughout this disclosure, and the terms "actual repetition," "actual copy," and "actual repeated transmission" are interchangeable throughout this disclosure.

[0205] In some embodiments, for PUSCH repetition type B with type 1 configured grant (Type 1 CG), after RRC configuration, after waiting for a certain activation time, PUSCH repetition type B can be periodically sent on the configured time-frequency resources using the configured transmission parameters.

[0206] In some embodiments, for PUSCH repetition type B with Type 2 configuration grant (Type 2 CG):

[0207] 1. Some RRC configuration parameters: cycle, open-loop power control, waveform, redundancy version, number of repetitions, frequency hopping and number of HARQ processes, etc.

[0208] 2. DCI activation and configuration: time domain resources, frequency domain resources, demodulation reference signal (DMRS) and / or modulation and coding scheme (MCS) and other parameters (determine the activation time);

[0209] 3. Combined with the RRC configuration and DCI activation and configured time-frequency resources, periodically send PUSCH repetition type B;

[0210] 4. The terminal needs to send an information element in the Media Access Control (MAC) control element (CE) to confirm the activation or deactivation of PUSCH repetition type B with type 2CG (to avoid confusion caused by not sending PUSCH when there is no UL data).
