Background
In a 5G communication system, there are data traffic with different priorities, latency requirements or transmission time intervals. For traffic channel transmissions of different terminals, it may happen that two data transmissions of different priorities collide on the same resource. For example, URLLC service with extremely high delay and high reliability needs occurs sporadically and irregularly, after the base station schedules the enhanced mobile bandwidth eMBB service, it receives a service request for scheduling URLLC of another terminal, and the resource of the URLLC service will conflict with the scheduled eMBB service.
In order to avoid interference of the low-priority service to the high-priority service, some measures, such as stopping data of the low-priority terminal, are required to be taken to ensure transmission of the high-priority service. However, the data of the stopped low priority terminal needs to be retransmitted. Thus, after the notification service stops transmitting, the terminal needs to be notified to retransmit, which may result in a sudden increase of signaling overhead.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the service transmission processing method according to the embodiment of the present invention includes:
the indication information comprises service channel transmission stop information and rescheduling information;
the traffic channel transmission stop information is used for indicating to stop the transmission of the first traffic channel, and the rescheduling information is used for indicating the time domain position and/or the frequency domain position of the retransmission or the reception of the first traffic channel.
The method of the embodiment of the invention is applied to user equipment (terminal), and the indication information sent by the base station is received through step 101, wherein the indication information comprises service channel transmission stop information and rescheduling information, the service channel transmission stop information is used for indicating to stop the transmission of the first service channel, and the rescheduling information is used for indicating the time domain position and/or the frequency domain position of the retransmission or the reception of the first service channel, so that the terminal can stop the channel transmission and reschedule the service channel aiming at the first service channel based on the indication information, and the signaling overhead of rescheduling is greatly saved.
The indication information is transmission management of a traffic channel (first traffic channel) corresponding to the first service. Generally, the indication information in this embodiment is sent by the base station to ensure that the transmission of the second traffic channel with higher priority is realized in the case that the base station schedules the traffic channel of the second traffic (traffic with higher priority than the first traffic) and the resource used by the traffic channel of the second traffic (second traffic channel) conflicts with the resource used by the first traffic channel.
For example, after the base station schedules the eMBB service, a service request for scheduling URLLC of another terminal is received, and the resource of the URLLC service may conflict with the resource of the scheduled eMBB service. At this time, the base station sends the indication information, so that the corresponding terminal can preferentially transmit the URLLC traffic channel and complete the transmission of the eMBB traffic channel while saving signaling overhead.
In this embodiment, based on the scheduled first service, optionally, step 101 includes:
detecting reception of the indication information at a configured control channel resource location.
In this way, the terminal can detect the configured control channel resource location so as to receive the indication information in time.
Furthermore, it should be appreciated that there may be a plurality of terminals affected by the second service, and therefore, in this embodiment, optionally, step 101 includes:
and receiving the indication information through the downlink control information carried by the group common downlink control channel.
In this way, the base station may group a plurality of terminals (terminals affected by the second service), and transmit the indication information through the downlink control information DCI (i.e., group common DCI) carried by the group common (group common) downlink control channel, so as to reduce signaling overhead for transmitting to each terminal. Accordingly, the terminal can receive the indication information through the group common DCI. Of course, if the second service only affects one terminal, the indication information may be received directly through the DCI carried by the downlink control channel.
Specifically, in order to facilitate a plurality of terminals to accurately obtain respective corresponding information, a user-specific indication field of the downlink control information carries the rescheduling information, and the rescheduling information corresponds to the terminals in the group one to one.
Here, the correspondence between each bit field (bit field) bit field of the user-specific UE specific indication field of the group common DCI and the terminal is pre-configured, for example, by high layer signaling. Each terminal can obtain respective rescheduling information at the bit field corresponding to the UEspecific indication field.
Optionally, the downlink control information is scrambled by a preset radio network temporary identifier.
Here, the DCI is scrambled by a preset radio network temporary identifier RNTI, so as to improve the security of the DCI. For example, the preset RNTI may be an X-RNTI.
In addition, to implement retransmission of the first traffic channel, optionally, the rescheduling information includes: offset information indicating a time domain offset and/or a frequency domain offset.
In this way, the terminal can retransmit the first traffic channel in the new resource.
Wherein the offset information includes:
a time domain offset and/or a frequency domain offset; alternatively, the first and second electrodes may be,
a combination of time domain offset and frequency domain offset.
As such, in one aspect, the offset information may be a specific offset in the time and/or frequency domain; on the other hand, the offset information may be a corresponding combined identifier of a preconfigured time domain offset and a frequency domain offset.
Specifically, the offset information in the rescheduling information includes a time domain offset M, which indicates a distance that a time domain position of the rescheduled data channel resource is offset backwards by M in a time domain relative to the cancelled data channel resource, where the offset M may be an offset of a slot (group) granularity or a symbol (group) granularity. If the offset information in the rescheduling information includes a frequency domain offset N, the frequency domain position of the rescheduled data channel resource is offset by N relative to the cancelled data channel resource, and the offset N may be a physical resource block PRB (group) granularity or an offset in a certain proportion of the working bandwidth.
The combination identifier of the time domain offset and the frequency domain offset is preset. For example, the network side configures the combinations of Q groups of time domain offsets and frequency domain offsets in advance through high layer signaling, and each combination has a unique combination identifier, such as ceil (log)2(Q)) bits. Through the combined identification, the time domain frequency domain offset of the rescheduled service channel relative to the cancelled data channel can be informed.
In this embodiment, optionally, the indication information further includes: a valid identification of the rescheduling information.
The effective mark is used for indicating whether to use the rescheduling information in the indicating information, if the effective mark is a specific bit information bit, the effective mark uses '0' and '1' to indicate, and if the effective mark does not use the rescheduling information in the indicating information, the transmission of the first service channel is stopped only based on the indicating information without rescheduling; the valid flag is "1" indicating that the rescheduling information in the indication information is used, and then the rescheduling information in the indication information is used for retransmission after the transmission of the first traffic channel is stopped based on the indication information.
For example, there are already multiple URLLC traffic schedules in the configuration bandwidth of UE1#, and many available scheduling resources are affected; or other available resources are already used for the eMB service transmission of other terminals, the base station indicates that the rescheduling information in the indication information is not used by the effective identifier in the indication information, after the terminal detects the indication information, the effective identifier, for example, the offset bits information bits of the rescheduling information are all 0, or the terminal indicates through a specific indication bit information bit, for example, 1 bit information "0" is used to indicate that the rescheduling operation is not performed, the terminal only performs the operation of canceling the service transmission, and does not perform the operation of retransmitting the service.
Optionally, after step 101, the method further comprises:
stopping transmission of the first traffic channel according to the traffic channel transmission stop information;
and retransmitting the first service channel according to the rescheduling information.
In this case, if the indication information further includes the valid flag, the valid flag indicates to use the rescheduling information in the indication information. After receiving the indication information, the first service channel transmission can be stopped according to the service channel transmission stop information, the second service channel transmission is preferentially carried out, and then the first service channel retransmission is carried out according to the rescheduling information.
For a plurality of terminals in the group, the indication information does not need to set service channel transmission stop information one by one corresponding to the terminals, and each terminal can be informed of stopping the transmission of the first service channel only by carrying one service channel transmission stop information.
Specifically, the stopping the transmission of the first traffic channel according to the traffic channel transmission stop information in consideration of the use state of the first traffic channel includes:
canceling the transmission or reception of the first traffic channel when the transmission of the first traffic channel is not started;
stopping transmission or reception of the first traffic channel when the first traffic channel has started transmission.
Thus, for the situation that the transmission of the first traffic channel is not started, the transmission or the reception of the first traffic channel can be directly cancelled; and if the first traffic channel starts transmission, stopping the transmission or reception of the subsequent first traffic channel.
The retransmitting the first traffic channel according to the rescheduling information, as shown in fig. 2, includes:
According to step 201 and 203, the terminal receiving the indication information may obtain the target rescheduling information corresponding to itself from the indication information, so as to determine the target resource used for retransmission in combination with the target rescheduling information and the original scheduling information of the first service, and then perform retransmission of the first service channel through the target resource.
As can be seen from the above, the rescheduling information is used to indicate the time domain position and/or the frequency domain position of the retransmission or reception of the first traffic channel, and may only include offset information of the position. Therefore, in order to accurately obtain the target resource used by the retransmission, the original scheduling information of the first service needs to be combined. The original scheduling information includes, but is not limited to, frequency domain resource allocation information, time domain resource allocation information, frequency domain frequency hopping identifier, modulation and coding scheme information, redundancy version information RV, hybrid automatic repeat request process number HARQ process number, transmit power control TPC command, and downlink control information format DCI format identifier.
Hereinafter, an application of the service transmission processing method according to the embodiment of the present invention will be specifically described with reference to the drawings.
In a first scenario, as shown in fig. 3, the network side schedules an eMBB service channel of the terminal UE # 1 to be transmitted in slot # n +1, and occupies all 14 symbols in the slot; meanwhile, an eMBB service channel of the terminal UE # 2 is scheduled to be transmitted in a slot # n +1, the 2 nd to 7 th symbol resource positions in the slot are occupied, and the two eMBB service channels respectively occupy different frequency domain resource positions. Before the transmission of the eMBB service channel, the network side schedules the URLLC service channel of the terminal UE # 3 at the slot # n to transmit at the slot # n +1, occupies the resource positions of the 4 th symbol and the 5 th symbol, and conflicts with the eMBB service resources of the UE # 1 and the UE # 2 on the frequency domain resources.
The base station sends indication information X at slot # n, group common DCI is adopted for carrying, the DCI is scrambled through a specific RNTI such as an X-RNTI, the DCI contains bit fields of different UEs, the corresponding relation between each bit field and a terminal is configured through high-layer signaling, the UE specific indication field (rescheduling information) configured to each terminal by the base station is assumed to be 7bits, wherein the first 4bits are used for indicating time domain offset, the second 3bits are used for indicating frequency domain offset, and the time domain offset granularity can be a symbol, or a symbol group, or a half slot, X times of slot length, and the frequency domain offset granularity can be a PRB, or a PRB group, or a certain proportion of UE bandwidth (such as working bandwidth of 1/4, working bandwidth of 1/2, and the like). In this embodiment, it is assumed that the time domain offset granularity configured by the base station is at a symbol level, the frequency domain offset indication granularity is a PRB group, and each PRB group is 12 PRBs, then the 4bits indication domain of the time domain offset can indicate the offset of 16 symbols at most, and the 3bits indication domain of the frequency domain offset can indicate the offset distance of 96 PRBs at most.
And after detecting that the scheduling information of the eMBB service data channel is received, the UE # 1 and the UE # 2 start to detect and receive the indication information X at the configured resource position, and when the UE # 1 and the UE # 2 detect the indication information X, the transmission process of the eMBB service channel is immediately cancelled.
Through the corresponding relation of high-level configuration, the UE # 1 detects and obtains rescheduling information carried in a bit field related to the UE # 1, and supposing that the bit of the rescheduling information is '0000 | 011', the first 4bits indicate that the time domain offset of the scheduling resource is 0, namely, the time domain offset is not offset, and the last 3bits indicate that the frequency domain offset of the scheduling resource is 3 PRB groups, namely, 36 PRBs are offset. UE # 1 can therefore retransmit based on the scheduling information (original scheduling information) that the terminal has cancelled the transport block TB, with the retransmitted resource being offset in the frequency domain by the position of 36 PRBs relative to each other.
Through the corresponding relation of high-level configuration, the UE # 2 detects and obtains the rescheduling information carried in the bit field relevant to the UE # 2, and supposing that the bit of the rescheduling information is detected to be '0111 | 000', the first 4bits indicate that the time domain offset of the scheduling resource is 7 symbols, and the last 3bits indicate that the frequency domain offset of the scheduling resource is 0, namely the frequency domain is not offset. UE # 2 can therefore perform retransmission based on the scheduling information that the terminal has cancelled the TB, with the retransmitted resource being relatively shifted by 7 symbol positions in the time domain.
In addition, if a plurality of sets of combinations of time domain offsets and frequency domain offsets are configured in advance through higher layer signaling on the network side, it is assumed that 8 sets of combinations { M, N } of the time domain offsets and the frequency domain offsets are configured in advance to respectively represent time domain offsets and frequency domain offsets, and that 8 combinations are {0 symbol, 36PRB }, {7 symbol, 36PRB }, {14 symbol, 36PRB }, {0 symbol, 72PRB }, {7 symbol, 72PRB }, {14 symbol, 0 PRB }, and can be defined as sequence corresponding combination numbers 0-7, in the indication information X, the time domain offsets and the frequency domain offsets are represented by combination identifiers, and a specific combination is not required to be transmitted, so that each UE specifical domain (rescheduling information) can be indicated by 3-bit information.
Thus, through the corresponding relationship of the high-level configuration, the UE # 1 detects and obtains the rescheduling information carried in the bit field related to itself, and assumes that the rescheduling information bit is '000', and corresponds to the combination {0 symbols, 36 PRBs } numbered 0, i.e. the time domain offset is 0, and the frequency domain offset is 36 PRBs. Therefore, UE # 1 can perform retransmission based on the scheduling information that the terminal has cancelled the TB, with the retransmitted resource being offset in the frequency domain by the position of 36 PRBs.
Through the corresponding relationship configured in the high layer, the UE # 2 detects and obtains the indication information carried in the bit field related to itself, and assumes that the bit of the indication information is '110', and corresponds to the combination {7 symbols, 0 PRB } numbered 6, i.e. the time domain offset is 7 symbols, and the frequency domain offset is 0. UE # 2 can therefore perform retransmission based on the scheduling information that the terminal has cancelled the TB, with the retransmitted resource being relatively shifted by 7 symbol positions in the time domain.
In scenario two, as shown in fig. 4, it is assumed that the network side schedules the eMBB traffic channel of the terminal UE # 1 to be transmitted in slot # n +1, and occupies all 14 symbols in the slot. Before the transmission of the eMBB service channel, the network side schedules the URLLC service channel of the terminal UE # 2 at the slot # n to be transmitted at the slot # n +1, occupies the resource positions of the 4 th symbol and the 5 th symbol, and conflicts with the eMBB service resource of the UE # 1 on the frequency domain resource.
The base station sends indication information X in slot # n, group common DCI is adopted to carry information, the DCI is scrambled through a specific RNTI such as an X-RNTI, the DCI contains bit domain information of different UE, the corresponding relation between each bit field and a terminal is configured through high-level signaling, and the indication method of canceling service transmission and retransmitting can be also adopted by adopting a time domain offset and/or a frequency domain offset or an indication method of a combined identifier of the time domain offset and the frequency domain offset.
After detecting and receiving the scheduling information of the eMB service data channel, the UE # 1 starts to detect and receive the indication information X at the configured resource position, when the UE # 1 detects the indication information X, the UE # 1 immediately cancels the data transmission of the 4 th and 5 th symbols of the eMB service channel, and the data of other unaffected symbol resource positions continues the transmission process.
