Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.
After receiving GC-PDCCH carrying SFI, UE supports cancellation of semi-static DL data reception of corresponding RRC configuration in corresponding time slot (slot); and canceling the semi-static UL transmission configured by the corresponding RRC after the last symbol of the GC-PDCCH starts to N2 symbols, wherein the processing time N2 is a time interval of corresponding Uplink scheduling to corresponding Physical Uplink shared channel (PUSCH SHARE CHANNEL) data transmission, and the granularity is the symbol level. When the SFI in the GC-PDCCH received by the UE indicates that the slot is DL or flexible resource (flexible), if the interval between the last symbol of the downlink control information (DCI, downlink Control Information) and the first symbol of the corresponding uplink transmission is less than N2, the UE may continue to transmit semi-static UL transmission configured by RRC. If the interval between the symbol of the last DCI and the first symbol of the corresponding uplink transmission is greater than or equal to N2, semi-static UL transmission of RRC configuration cannot be transmitted.
The inventor of the present application has found after careful study that when a UE is configured with more than one RRC configured semi-static uplink transmission in one slot, the at least one RRC configured semi-static uplink transmission satisfies the interval less than N2, and the at least one RRC configured semi-static uplink transmission does not satisfy the interval less than N2. In this case, according to the current protocol, semi-static uplink transmission of RRC configuration with an interval less than N2 can be transmitted, and semi-static uplink transmission of RRC configuration with an interval not less than N2 cannot be transmitted, but the order of the slot structure types is DL-Un-UL according to the current frame structure, that is, when DL symbols are no longer present after UL symbols in one slot (even if DL symbols appear after UL, there is no great significance in leaving several DL symbols at the end of one slot), it is obvious that if semi-static uplink transmission of RRC configuration with an interval less than N2 cannot be transmitted in one slot is not reasonable. Accordingly, the present application proposes a method of handling uplink transmissions, comprising:
The UE receives a GC-PDCCH carrying an SFI, wherein the time slot format indicated by the SFI is DL or flexible; when the UE is configured with more than one RRC configured semi-static UL transmission in one slot, where at least one RRC configured semi-static UL transmission satisfies that the interval between the last symbol of the GC-PDCCH and the first symbol of the RRC configured semi-static UL transmission is less than the processing time N2 of the UE, then all RRC configured semi-static UL transmissions in the slot are transmitted in the slot.
Optionally, in addition to the above-mentioned at least one RRC configured semi-static UL transmission satisfying the interval between the last symbol of the GC-PDCCH and the first symbol of the RRC configured semi-static UL transmission being smaller than the processing time N2 of the UE, the other RRC configured semi-static UL transmissions in the slot satisfy: the interval between the last symbol of the GC-PDCCH and the first symbol of the semi-static UL transmission of the other RRC configuration is greater than or equal to the processing time N2 of the UE.
The method for processing the semi-static uplink transmission of the RRC configuration reasonably realizes the processing of the semi-static uplink transmission of the RRC configuration after receiving the GC-PDCCH carrying the SFI.
In one embodiment of the present application, fig. 1 is a flowchart of an embodiment of the method for processing UL transmissions of the present application, as shown in fig. 1, comprising the steps of:
Step 100: and the UE receives the GC-PDCCH carrying the SFI and determines that the UE has more than one type of semi-static uplink transmission configured by RRC in one time slot.
The slot format indicated by the SFI is DL or flexible, as specified in the related art.
Please refer to the related art for the specific implementation of this step, and the detailed description is omitted here.
Step 101: if one of the RRC configured semi-static UL transmissions satisfies that the interval between the last symbol of the GC-PDCCH and the first symbol of the RRC configured semi-static UL transmission is less than the processing time N2 of the UE, then the RRC configured semi-static UL transmissions in the slot are all transmitted.
Optionally, in addition to the above-mentioned at least one RRC configured semi-static UL transmission satisfying the interval between the last symbol of the GC-PDCCH and the first symbol of the RRC configured semi-static UL transmission being smaller than the processing time N2 of the UE, the other RRC configured semi-static UL transmissions in the slot satisfy: the interval between the last symbol of the GC-PDCCH and the first symbol of the semi-static UL transmission of the other RRC configuration is greater than or equal to the processing time N2 of the UE.
Optionally, in one embodiment of the present application, the semi-static UL transmission of the RRC configuration includes one or any combination of the following:
