Embodiment 1
[0113] According to the current standard, through RRC configuration, K=4, RV={0 3 0 3}, the time domain resource position is {start OFDM symbol, number of OFDM symbols}, this time domain resource position is defined as a transmission opportunity TO , that is, resources for completing one repeated transmission, and K=4 means that four repeated transmissions are required, and four TOs are required. Here TO is usually continuous.
[0114] Considering that the uplink data packet of UE (User Equipment, user equipment) arrives after the first TO and before the third TO in a TWG (transmission without grant, scheduling-free transmission) configuration period, then the UE will transmit in the third TO The PUSCH with RV=0 and the PUSCH with RV=3 are transmitted in the fourth TO. According to the current standard, no other transmission will be performed in this resource period. The base station blindly detects the PUSCH. Under normal circumstances, PUSCHs with different RVs should be de...
Embodiment 2
[0120] According to the current standard, through RRC configuration, K=4, RV={0 3 0 3}, the time domain resource position is {start OFDM symbol, number of OFDM symbols}, this time domain resource position is defined as a transmission opportunity TO , that is, resources for completing one repeated transmission, and K=4 means that four repeated transmissions are required, and four TOs are required. Here TO is usually continuous.
[0121] Considering that after the terminal’s uplink data packet transmits PUSCH with RV=0 in the first normal TO within a TWG configuration cycle, it receives dynamic SFI configuration information, making the subsequent normal TOs unusable, such as the last two normal TOs If it cannot be used, the terminal will transmit the PUSCH in the first normal TO and the second normal TO, then in the third normal TO and in the fourth normal TO, according to the current standard, it will no longer to transfer. The base station blindly detects the PUSCH. Under no...
Embodiment 3
[0127] According to the current standard, when the terminal transmits data to the base station, the base station configures resources for the terminal through RRC. The time domain resource position is {start OFDM symbol, the number of consecutive OFDM symbols}; the frequency domain resource position is according to type (type) 0 or a PRB (Physical Resource Block, physical resource block) set allocated in a type1 manner.
[0128] The time-domain resource location and the frequency-domain resource location are defined as a transmission opportunity TO, that is, to complete a repeated transmission, such as K=4, RV={0 3 0 3}, which means that 4 repeated transmissions need 4 TOs. The TO here usually appears in K consecutive time slots.
[0129] If there are 4 normal TOs in a TWG configuration period, and the uplink data packet of the terminal arrives after the first TO and before the third TO in the TWG configuration period, then the terminal will transmit RV=0 through the third TO ...
