In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a resource conflict handling method according to an embodiment of the present invention.
The resource conflict processing method shown in fig. 1 may be used on the user equipment side. The resource conflict processing method can comprise the following steps:
step S101: receiving resource allocation of uplink transmission and resource allocation of a side link configured by a base station;
step S102: determining the resource overlapping position of the resource for uplink transmission and the resource for the side link according to the resource configuration of the uplink transmission and the resource configuration of the side link;
step S103: determining to drop uplink transmission at least at the resource overlapping location according to the type of the side link, or determining whether to drop the uplink transmission at least at the resource overlapping location according to the priority of the side link.
In a specific implementation, the base station may configure uplink transmission resources for uplink transmission and side link resources for side links for the UE. The base station may send the resource configuration of the uplink transmission and the resource configuration of the side link to the UE, where the resource configuration may specifically be a time-frequency location of the resource.
In a specific implementation of step S101, the UE may receive a resource configuration of uplink transmission and a resource configuration of an edge link configured by the base station. Therefore, the UE can acquire the time-frequency position of the uplink transmission resource and the time-frequency position of the side link resource.
Further, in the specific implementation of step S102, the UE may determine the resource overlapping position according to the resource configuration of the uplink transmission and the resource configuration of the side link.
Specifically, referring to fig. 2, fig. 2 shows resource overlapping positions in three application scenarios.
As shown in fig. 2, the horizontal axis represents a frequency domain, and the dotted line portion represents a shared carrier (shared carrier) of uplink and side links.
In scenario a, a Side Link (SL) resource is included in an UpLink (UpLink, UL) resource, and the resource overlapping position is a position of the SL resource on a frequency domain. In scenario b, the UL resource is included in the SL resource, and the resource overlapping position is a position of the UL resource on the frequency domain. In scenario c, the UL resource and the SL resource partially overlap in the frequency domain, where the resource overlapping position is an overlapping position of the UL resource and the SL resource in the frequency domain.
In a specific implementation of step S103, determining whether to discard uplink transmission at least at the resource overlapping position according to the type of the side link; or determining whether to discard the uplink transmission at least at the resource overlapping position according to the priority of the side link. In other words, it is determined to drop the uplink transmission or drop the side link at least at the resource overlapping position according to the priority of the side link.
Specifically, the UE may discard the uplink transmission only at the resource overlapping position; the UE may also drop uplink transmissions on resources used for uplink transmissions.
Preferably, the UE discards the uplink transmission on the entire UL resource.
In a variation of the present invention, the UE may discard the side link transmission only at the resource overlapping position, or may discard the side link transmission on the resource used for the side link transmission, for example, refer to scenario a, scenario b, and scenario c shown in fig. 2. In scenario a, the resource overlapping position (i.e. SL resource) occupies a part of the UL resource, and the UE may discard uplink transmission only in the SL resource and still perform uplink transmission in other UL resource positions except the SL resource. Alternatively, the UE may also drop uplink transmissions on the entire UL resource. Alternatively, the UE may drop the sidelink transmission over the entire SL resource.
In scenario b, the resource overlapping position is an UL resource, and the UE may discard uplink transmission on the entire UL resource. Alternatively, the UE may drop the sidelink transmission over the entire UL resource. Alternatively, the UE may drop the sidelink transmission over the entire SL resource.
In scenario c, the resource overlapping position occupies a part of the UL resource, and the UE may discard the uplink transmission only in the resource overlapping position, and still perform the uplink transmission in other UL resource positions except the resource overlapping position. Alternatively, the UE may also drop uplink transmissions on the entire UL resource. Or the UE may discard the side link transmission only at the resource overlapping position, and still perform the side link transmission at other UL resource positions outside the resource overlapping position. Alternatively, the UE may also drop the sidelink transmission over the entire SL resource.
In this embodiment, the UE preferentially performs the sidelink transmission. That is, if the uplink transmission and the side link have resource collision, the UE directly discards the uplink transmission.
In the embodiment of the invention, the user equipment can determine the resource overlapping position of the uplink transmission and the side link by aiming at the resource configuration of the uplink transmission and the side link through the base station; according to the type of the side link or the priority of the side link, the user equipment can directly discard the uplink transmission at the overlapped resource position, namely, the side link transmission is executed at the overlapped resource position; the user equipment can also discard the side link according to the priority of the side link, so that the user equipment can smoothly transmit data at the overlapped resource position, and further, the communication efficiency between the devices under the V2X scene is ensured.
In an embodiment of the present invention, step S103 shown in fig. 1 may include the following steps: discarding uplink transmissions at least at the resource overlap location if the type of the side link is selected from a first set of transmission types.
In this embodiment, for the side link corresponding to each transmission type in the first transmission type set, the base station does not configure the priority. The uplink transmission may be dropped directly if the edge link that creates a resource conflict with the uplink transmission is selected from the first set of transmission types.
In particular, the first set of transmission types comprises types of one or more of the following side links: PSSCH, PSSCH with SR carrying scheduling request, PSSCH with CSI (channel State information) carrying channel state information, (PSSCH with CSI), PSSCH with HARQ-ACK (PSSCH with HARQ-ACK), PSSCH with channel state information and HARQ-ACK (PSSCH with CSI and HARQ-ACK), PSSCH with scheduling request and HARQ-ACK, PSSCH with scheduling request and channel state information, PSSCH with HARQ-ACK and channel state information, PSCCH with SR with scheduling request, PSCCH with CSI with channel state information, (PSCCH with CSI) with channel state information, PSCCH with HARQ-ACK (PSCCH with HARQ-ACK), PSCCH with CSI with channel state information and HARQ-ACK), PSCCH with channel state information and HARQ (PSCCH with CSI and HARQ-ACK), PSCCH with CSI with channel state information and scheduling request, (PSCCH with CSI and SR), PSCCH (PSCCH with SR and HARQ-ACK) carrying scheduling request and HARQ-ACK, PSCCH (PSCCH with SR and CSI and HARQ-ACK) carrying scheduling request and channel state information and HARQ-ACK, PSCCH (PSCCH with TPC) carrying transmission power control, PSCCH (PSCCH with SFI) carrying slot format indication information, side link feedback channel carrying scheduling request, side link feedback channel carrying channel state information, side link feedback channel carrying HARQ-ACK, side link feedback channel carrying channel state information and scheduling request, side link feedback channel carrying scheduling request and HARQ-ACK, side link feedback channel carrying scheduling request and channel state information and HARQ-ACK, PSDCH, SLSS, PSBCH, SL-CSIRS for beam management, SL-CSIRS for channel state information acquisition, SL-SRS for beam management (beam management), SL-SRS for antenna switching (antenna switching), SL-SRS for codebook transmission (codebook), SL-SRS for non-codebook transmission (non-codebook), SL-SRS, SL-CSIRS, SL-SSB (e.g., SLSS and PSBCH), side link sounding reference signals, side link channel state information and scheduling request, AGC training signals, unicast (unicast) transmission, multicast (groupcast) transmission, broadcast (broadcast) transmission, multicast and broadcast transmission, unicast and multicast transmission, unicast and broadcast transmission, side link transmission.
In another embodiment of the present invention, step S103 shown in fig. 1 may include the following steps:
and determining to discard the uplink transmission or discard the side link transmission at the resource overlapping position according to the priority of the side link.
In a specific implementation, the base station may configure a priority corresponding to the side link transmission, and the priority corresponding to the side link transmission may indicate the transmission importance of the side link. Under the condition of higher priority, the UE preferentially executes side link transmission, namely discards uplink transmission; and under the condition of lower priority, the UE preferentially executes uplink transmission, namely, side link transmission is discarded.
Further, the priority is a priority indication value in the sidelink control information; the determining to discard the uplink transmission or discard the sidelink at the resource overlapping position according to the priority comprises the following steps:
if the priority indicated value in the side link control information is smaller than a preset threshold value configured by the base station, determining to discard uplink transmission at the resource overlapping position; and if the priority indicated value in the side link control information is larger than the preset threshold value, determining to discard the side link at the resource overlapping position. Wherein the threshold may be configured by higher layer signaling (e.g., RRC signaling).
In this embodiment, the lower the priority indication value in the side link control information is, the higher the priority of the side link is. Specifically, if the priority indication value in the sidelink control information is smaller than the preset threshold configured by the base station, it indicates that sidelink transmission needs to be preferentially performed, and the UE may discard the uplink transmission. The priority indication value in the side link control information being greater than the preset threshold value indicates that the importance of the side link is crossed, and the UE may drop the side link to perform uplink transmission.
Further still, the type of sidelink corresponding to the priority indication value in the sidelink control information is selected from the second set of transmission types. The second set of transmission types includes types of one or more of the following side links: PSSCH carrying HARQ-ACK, PSSCH carrying channel state information and HARQ-ACK, PSSCH carrying scheduling request and HARQ-ACK, PSSCH carrying scheduling request and channel state information, PSSCH carrying scheduling request and HARQ-ACK and channel state information, PSSCH, PSCCH carrying HARQ-ACK, PSCCH carrying channel state information and HARQ-ACK, the PSCCH carrying the scheduling request and the HARQ-ACK, the PSCCH carrying the scheduling request and the channel state information and the HARQ-ACK, an edge link feedback channel carrying the scheduling request, an edge link feedback channel carrying the HARQ-ACK, an edge link feedback channel carrying the channel state information and the HARQ-ACK, an edge link feedback channel carrying the scheduling request and the HARQ-ACK, and an edge link feedback channel carrying the scheduling request and the channel state information and the HARQ-ACK.
Specifically, when determining whether to discard at least the pschs carrying HARQ-ACK (e.g., carrying HARQ-ACK, carrying channel state information, and HARQ-ACK), the priority indication value in the scheduling SCI of the psch corresponding to HARQ-ACK may be referred to; when determining whether to discard the PSCCH, the method may refer to a priority indication value in an SCI corresponding to the PSCCH; when determining whether to discard at least PSCCHs carrying HARQ-ACK (such as PSCCHs carrying HARQ-ACK, channel state information, and HARQ-ACK, scheduling request, and channel state information, and HARQ-ACK), a priority indication value in a scheduling SCI of the PSCCH corresponding to HARQ-ACK may be referred to; when determining whether to discard the side link feedback channel, the priority indication value in the SCI corresponding to the side link feedback channel may be referred to; when determining whether to discard at least the side link feedback channel carrying HARQ-ACK (e.g., carrying HARQ-ACK, carrying channel state information and HARQ-ACK, carrying scheduling request and channel state information and HARQ-ACK), the priority indication value in the scheduling SCI of the psch corresponding to HARQ-ACK may be referred to.
HARQ-ACKHARQ-ackhaarq-ackhak further, the priority is a priority indication value in the channel state information; the determining to discard the uplink transmission or discard the sidelink at the resource overlapping position according to the priority comprises:
if the priority indicated value in the channel state information is smaller than a preset threshold value configured by the base station, uplink transmission is determined to be discarded at the resource overlapping position; and if the priority indicated value in the channel state information is larger than the preset threshold value, determining to discard the side link at the resource overlapping position. Wherein the threshold may be configured by higher layer signaling (e.g., RRC signaling).
In this embodiment, the priority indication value in the channel state information may also indicate the priority of the sidelink. The priority indication value in the channel state information being smaller than the preset threshold value configured by the base station indicates that the importance of the side link is higher, and the UE may discard the uplink transmission to execute the side link transmission. The priority indication value in the channel state information is greater than the preset threshold value, which indicates that the importance of the sidelink is low, and the UE may discard the sidelink to perform uplink transmission. Specifically, the priority indication value in the channel state information may be determined by its content, a periodic, aperiodic or semi-persistent (semi-persistent), and a report sequence number (reportID).
More further, the sidelink that employs the priority indication value in the channel state information is selected from a third set of transmission types, the third set of transmission types including one or more of the following sidelink types: the PSSCH carrying channel state information, the PSSCH carrying channel state information and HARQ-ACK, the PSCCH carrying channel state information and HARQ-ACK, the PSCCH carrying channel state information and scheduling request, the side link feedback channel carrying channel state information, the PSCCH carrying scheduling request, channel state information and HARQ-ACK, the side link feedback channel carrying channel state information and scheduling request, the side link feedback channel carrying channel state information and HARQ-ACK, and the side link feedback channel carrying scheduling request, channel state information and HARQ-ACK.
In this embodiment, for the sidelink carrying the channel state information, it may be determined to discard the uplink transmission or the sidelink based on the priority indication value of the channel state information configured by the base station.
In a preferred embodiment of the present invention, the uplink transmission is selected from PRACH transmission and non-PRACH transmission.
In this embodiment, the uplink transmission with resource conflict with the side link may be PRACH transmission or non-PRACH transmission. The UE may directly discard the side link transmission or the non-PRACH transmission or the PRACH transmission at least at the resource overlapping location. And if the priority indicated value in the side link control information or the priority indicated value in the channel state information exists, determining whether to discard the PRACH transmission or not according to the priority indicated value.
