Wireless communication and in particular, to transmission for Ultra-Reliable Low Latency Communications (URLLC) Uplink Control Information (UCI).
URLLC traffic has been identified as one traffic group to be served in wireless networks, such as, for example, New Radio (NR). As compared to enhanced Mobile Broadband (eMBB) traffic, URLLC traffic may be considered to have the following characteristics:
In 3rd Generation Partnership Project (3GPP), the following aspects may be considered:
Other considerations include performing more reliable transmission of UCI based on different service types. However, how to implement more reliable transmission is quite challenging.
It may be considered that, for UCI on the Physical Uplink Shared Channel (PUSCH), support for both dynamic and semi-static beta offset, βoffset, indication is provided. For dynamically scheduled PUSCH transmission, a plurality of sets of beta offset values can be configured by Radio Resource Control (RRC) signaling, and the PDCCH can dynamically indicate an index to a set of beta offset values. Each set of beta offset values may include a plurality of entries, each of the plurality of entries corresponding to a respective UCI type (including two-part CSI when applicable). The beta offset, βoffset, may be considered to be used for computing the amount of Resource Elements (REs) for each respective UCI on the PUSCH. UCI may include, for example, HARQ-ACK and CSI.
If a wireless device (WD) (e.g., user equipment (UE)) is configured with dynamic beta offset, four (4) sets of beta offset values may be configured for each Hybrid-ARQ-ACK (HARQ-ACK) (also called the HARQ ACK/NACK, HARQ acknowledge message, HARQ feedback, etc.) payload range and CSI payload range and type, respectively via RRC signaling. Also, two (2) bits in the Downlink Control Information (DCI) may indicate one out of the four (4) sets of beta offset values. Each set of beta offset values may include beta offset values for HARQ-ACK ranges and beta offset values for CSI payload ranges and type. The beta offset values may be given by:
It has been agreed that CSI is always split into CSI part 1 and CSI part 2 when CSI piggybacks on the PUSCH (with CSI type 1, CSI part 2 does not exist when there is no Precoding Matrix Indicators (PMI) and with rank up to 4).
As one example, the beta offset values can be configured as in Table 1.
It has been agreed that a good performance can be achieved when only eMBB or only URLLC is supported. However, for one terminal that supports eMBB and URLLC simultaneously at a given interval, the performance may not be optimized with the current agreed mechanism. For example, when a beta offset value is decided on, the RRC can be used to configure the beta offset value with an assumption of an eMBB service. In this case, when URLLC service is transmitted, the same sets of beta offset values are applied to both eMBB and URLLC services and thus, the performance of UCI for the URLLC services may not meet the high reliability requirements since the configured beta offset values may be too small for the reliable transmission of UCI. On the other hand, if RRC is used to configure the beta offset values with an assumption of URLLC service, resources may be wasted when only eMBB UCI is required.
Some embodiments advantageously provide methods and apparatuses for performing HARQ-ACK feedback and CSI reporting for concurrent services with different reliability and/or latency requirements (e.g., eMBB and URLLC).
In a first embodiment, a plurality of sets of beta offset values can be configured, and for each set of beta offset values, a plurality of subsets of beta offset values are defined for HARQ-ACK feedback, and each subset of beta offset values are associated with a service type.
In a second embodiment, a plurality of sets of beta offset values can be configured, and for each set of beta offset values, a plurality of subsets of beta offset values can be defined for CSI feedback; the subsets of beta offset values may be associated with one or more parameters configured in the CSI report configuration.

Other advantages of some embodiments of the present invention may include, but are not limited to, improving the CSI report reliability when the WD supports concurrent/simultaneous services with different reliability and/or latency requirements.

Having described some embodiments of the present disclosure, more detailed descriptions of some embodiments are provided herein below as follows.
Some embodiments provide methods and apparatuses for communicating information for UCI (e.g., HARQ-ACK feedback, CSI reporting, etc.) for concurrent services associated with a WD 22, the concurrent services having different reliability and/or latency requirements (e.g., eMBB and URLLC).
In the first embodiment, at least one set of beta offset values can be configured, and for each set of beta offset values, at least one subset of beta offset values is defined for HARQ-ACK feedback. As one further implementation of the first embodiment, each subset of beta offset values may be associated with one service type. As one example, one subset of beta offset values is associated with one service type, and the other subset of beta offset values is associated with the other service type. In a further example, one service type may be eMBB and the other service type may be URLLC.
There may be provided one or more techniques for the association of service types to subsets of beta offset values. As one example of such association, the subset of beta offset values may be associated with the indicator indicated in the DCI. For example, when the data is for eMBB services, the indicator may be “1” and otherwise, the indicator may be “0”. In such cases, when the indicator is “1”, the first subset of beta offset values may be used for HARQ-ACK feedback; otherwise, the second subset of beta offset values may be used for HARQ-ACK feedback.
As another example of the association of service types to subsets of beta offset values, the subset of beta offset values may be associated with the transmission parameters of one or more of control channels and data channels, in which the transmission parameters may include one or more of:
The above techniques for the association of service types to subsets of beta offset values maybe predefined in some embodiments, or, in other embodiments, RRC configured or configured by a MAC Control Element (MAC CE).
In a further embodiment of the first embodiment, at least one transmission rule is defined for HARQ-ACK feedback when HARQ-ACK for one type of service (e.g., eMBB) is concurrent with another type of service (e.g., URLLC). As one implementation of the transmission rules, the first subset of beta offset values may be used for HARQ-ACK transmission for the first service type and the second subset of beta offset values may be used for the HARQ-ACK transmission for the second service type. As another implementation of the transmission rules, the second subset of beta offset values may be applied to both service types for eMBB HARQ feedback and URLLC HARQ feedback.
As another implementation of transmission rules, the HARQ-ACK transmission for the first service type may be dropped and HARQ-ACK transmission for the second service type may be transmitted with the second subset of beta offset values. As yet another implementation, the HARQ-ACK transmission for the second service type may be prioritized and may be transmitted with the second subset of beta offset values, and the HARQ-ACK transmission for the first service type may be transmitted with the first subset of beta offset values if the total required resource is lower than a threshold; otherwise, the beta offset values for HARQ-ACK transmission of the first service type is scaled down so that the total required resource is lower than the threshold. As a further implementation, a second threshold may be given if the beta offset values for HARQ-ACK transmission of the first service type is scaled down and if the beta offset values are smaller than the second threshold, the HARQ-ACK transmission of the first service type may be dropped.
In the second embodiment, at least one set of beta offset values can be configured, and for each set of beta offset values, at least one subset of beta offset values can be defined for CSI feedback.
As one further implementation of the second embodiment, the subsets of beta offset values may be associated with one or more parameters configured in the CSI report configuration. According to some agreements, the CSI report configuration may include one or more of:
As one example, it may be assumed that the subsets of beta offset values are associated with the BLER_Target (also called target block error rate, target BLER, and BLER target), with the first subset of beta offset values being associated with a first BLER_Target (e.g., BLER_Target=10{circumflex over ( )}(−1)) and the second subset of beta offset values being associated with a second BLER_Target (e.g., BLER_Target=10{circumflex over ( )}(−5)). The first BLER_Target may be configured for CSI reporting for eMBB-related PDSCH/PDCCH transmission and the second BLER_Target may be configured for CSI reporting for URLLC-related PDSCH/PDCCH transmission. In one embodiment, when the CSI is reported for eMBB-related PDSCH/PDCCH transmission, the first subset of beta offset values may be used, and when the CSI is reported for URLLC-related PDSCH/PDCCH transmission, the second subset of beta offset values may be used. One example is shown herein below in Table 2.
In the third embodiment, at least one transmission rule may be defined for CSI feedback, in which the at least one transmission rule may be at least associated with one or more of a configured BLER-Target and/or a configured CQI-Table. As one further implementation of the third embodiment, at least one transmission rule is or includes a plurality of priority rules. As one implementation, a CSI report with a lower BLER target may be configured with a higher priority than a CSI report with a higher BLER target. In one embodiment, when CSI reports with different BLER targets is transmitted at the same time (concurrently/simultaneously), the transmission with higher priority may be prioritized and the transmission with lower priority is down prioritized. As one example of the implementation of the prioritization, when CSI reports with different BLER targets are transmitted at the same time, the CSI report with higher priority is transmitted and the CSI report with lower priority is dropped. As another example of the implementation of the prioritization, a CSI report is omitted level by level beginning with the lowest priority level until the lowest priority level is reached, which may cause the UCI code rate to be less than or equal to a given threshold, in some embodiments.
As one further embodiment of the third embodiment, CSI reports with the same BLER target may be grouped into, for example, a CSI report group. In one embodiment, the CSI report group priority may be proportional to the CSI report group BLER target. For example, a CSI report group may have a higher priority when the associated CSI report BLER target is lower, as compared to the BLER target(s) for other CSI reports transmitted concurrently therewith. The transmission in the CSI report group with higher priority is prioritized when two CSI report is transmitted at the same time. For the CSI reports, a plurality of alternatives may be used for the CSI reports' encoding. As one alternative, the CSI reports in the same CSI report group may be encoded jointly, and the CSI reports in one or more different CSI report groups may be encoded separately. As yet another alternative, the CSI reports for different report groups may be encoded jointly in some embodiments.
In one embodiment of the third embodiment, for CSI reports, a CSI report may comprise a plurality of parts. As one example of such embodiment, two parts are given in the following description. For Type I CSI feedback on the PUSCH, a CSI report may comprise up to two parts. Part 1 may include Rank Indication (RI/CRI), Channel Quality Indicator (CQI) for the first codeword. Part 2 may include PMI and may include the CQI for the second codeword when RI>4. For Type II CSI feedback on PUSCH, a CSI report may comprise up to two parts. Part 1 may be used to identify the number of information bits in Part 2. Part 1 may have a fixed payload size and may include RI, CQI, and an indication of the number of non-zero wideband amplitude coefficients per layer for the Type II CSI. The fields of Part 1—RI, CQI, and the indication of the number of non-zero wideband amplitude coefficients for each layer—may be separately encoded. Part 2 may include the PMI of the Type II CSI. Part 1 and 2 may in some embodiments be separately encoded.
As another further embodiment of the third embodiment, when a CSI report comprises a plurality of parts, at least one transmission rule may be defined for the CSI report parts. As one example shown in Table 3 herein below, CSI reports with the same BLER target may be grouped. As shown in the exemplary table, Table 3, Part I for the CSI report group with lower BLER target has the highest priority; Part I for CSI report group with higher BLER target has the second highest priority; Part II for the CSI report group with the lower BLER target has the third highest priority; and the Part II for CSI report group with the higher BLER target has the lowest priority. With this priority ordering, coarse link adaptation can be performed both for eMBB and URLLC in some embodiments.
In another embodiment, the priority reporting levels can also be provided as shown in Table 4. With this priority ordering shown in Table 4, URLLC CSI report can be guaranteed and the performance of URLLC can be improved, as compared to the embodiment shown in Table 3 where, for example, Part 1 for CSI report group with higher BLER target has a higher priority than Part 2 for CSI report group with lower BLER target.
Within Part 2 for each CSI report group, a further priority order may be provided. One such example priority order is shown in Table 5 herein below, where NRep is the number of CSI reports in one slot. Priority 0 is the highest priority and priority 2NRep is the lowest priority and the CSI report numbers correspond to the order of the associated ReportConfigID.
In some embodiments, for CSI reports, the WD may omit a portion of the lower priority CSI report based on Table 3 or Table 4, and further omission of Part 2 CSI may be according to the priority order shown in Table 5. When omitting Part 2 CSI information for a particular priority level, the WD may, in some embodiments, omit all of the information at that priority level.
In one embodiment, when the CSI is multiplexed with the UL-SCH on the PUSCH, Part 2 CSI may be omitted only when the UCI code rate for transmitting all of Part 2 would be greater than a threshold code rate cT, where
In one embodiment, Part 2 CSI may be omitted level by level beginning with the lowest priority level until the lowest priority level is reached, which may cause the UCI code rate to be less than or equal to cT.
As yet another example, Part 2 CSI may be omitted only when the code rate for PUSCH is modified more than a certain factor by sending UCI+PUSCH. In other words, if the change of the PUSCH code rate due to the UCI transmission exceeds a threshold, which may be a predetermined threshold (e.g., 10% higher than indicated in MCS) then the UCI is omitted.
In yet other embodiments of the present disclosure, all or a portion of the methods, apparatuses, and techniques described herein may also be used for data in the UCI other than CSI and HARQ-ACK, such as, for example, RI, PMI, etc.

It is to be understood that the functions/acts noted in the blocks may occur out of the order noted in the operational illustrations. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.
Computer program code for carrying out operations of the concepts described herein may be written in an object oriented programming language such as Java® or C++. However, the computer program code for carrying out operations of the disclosure may also be written in conventional procedural programming languages, such as the “C” programming language. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer. In the latter scenario, the remote computer may be connected to the user's computer through a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
Many different embodiments have been disclosed herein, in connection with the above description and the drawings. It will be understood that it would be unduly repetitious and obfuscating to literally describe and illustrate every combination and subcombination of these embodiments. Accordingly, all embodiments can be combined in any way and/or combination, and the present specification, including the drawings, shall be construed to constitute a complete written description of all combinations and subcombinations of the embodiments described herein, and of the manner and process of making and using them, and shall support claims to any such combination or subcombination.
It will be appreciated by persons skilled in the art that the embodiments described herein are not limited to what has been particularly shown and described herein above. In addition, unless mention was made above to the contrary, it should be noted that all of the accompanying drawings are not to scale. A variety of modifications and variations are possible in light of the above teachings without departing from the scope of the following claims.
