MULTIPLE TRANSMISSION OCCASIONS FOR UPLINK CONTROLINFORMATIONCROSS REFERENCE TO RELATED APPLICATION(S)
[0001] This application claims the benefit of and priority to U. S. Provisional ApplicationSerial No. 63 / 625,595, entitled “MULTIPLE TRANSMISSION OCCASIONS FOR UPLINK CONTROL INFORMATION” and filed on January 26, 2024, which is expressly incorporated by reference herein in its entirety.TECHNICAL FIELD
[0002] The present disclosure relates generally to wireless communication, and more particularly, to multiple transmission occasions for uplink control information (UCI).BACKGROUND
[0003] The Third Generation Partnership Project (3 GPP) specifies a radio interface referred to as fifth generation (5G) new radio (NR) (5GNR). An architecture for a 5G NR wireless communication system includes a 5G core (5GC) network, a 5G radio access network (5G-RAN), a user equipment (5G UE), etc. The 5G NR architecture seeks to provide increased data rates, decreased latency, and / or increased capacity compared to prior generation cellular communication systems.
[0004] Wireless communication systems, in general, provide various telecommunication services (e.g., telephony, video, data, messaging, etc.) based on multiple-access technologies, such as orthogonal frequency division multiple access (OFDMA) technologies, that support communication with multiple UEs. Improvements in mobile broadband continue the progression of such wireless communication technologies.BRIEF SUMMARY
[0005] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects. This summary neither identifies key or critical elements of all aspects nor delineates the scope of any or all aspects. Its sole purposeis to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
[0006] Uplink control information (UCI) carries control information from a user equipment (UE) to a network entity. The UE may transmit the UCI to the network entity via a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH). The UCI may include any combination of hybrid automatic repeat request (HARQ) acknowledgement / negative acknowledgement (ACK / NACK) feedback, scheduling request (SR), and / or channel state information (CSI). If multiple UCI reports are scheduled to be transmitted by the UE to the network entity in the same transmission occasion and not enough resources (e.g., PUCCH / PUSCH resources) are allocated, priority rules may dictate which UCI reports are transmitted and which UCI reports are discarded. In some aspects, the priority rules are defined based on the type of UCI report. In a non-limiting example, ACK / NACK may have a higher priority than SR and CSI, SR may have a higher priority than CSI.
[0007] In some aspects, if multiple UCI reports are associated with multiple transmission occasions and not all of the UCI reports (e.g., ACK / NACK, SR, and / or CSI) can be contained in the PUCCH / PUSCH resources allocated to a transmission occasion (e.g., an initial transmission occasion) , then priority rules may determine the order in which the UCI reports are scheduled for transmission in the multiple transmission occasions. In some aspects, the priority rules may determine the order in which the CSI reports (e.g., measured CSI report, predicted CSI report) are scheduled for transmission.
[0008] A UE may measure CSI (e.g., a rank indicator (RI), a precoder matrix indicator (PMI), a channel quality indicator (CQI), and a layer indicator (LI)) based on one or more CSI-RSs. In some aspects, a UE may predict CSI for a future term (e.g., a number of slots / milliseconds in the future). For example, a UE may use a machine learning function to predict CSI. In some aspects, the predicted CSI may be tolerant of delays in the UE transmitting the CSI to the network entity. Predicted CSI may be delay tolerant based on the prediction term being relatively long (e.g., 20 millisecond (ms)). In some aspects, measured CSI may not be delay tolerant (or delay-intolerant). For example, when the measured CSI changes rapidly, the network entity may use real-time CSI to determine the conditions of the channel and adapt downlink communications accordingly.
[0009] In some other aspects, measured CSI may be delay tolerant when the measured channel metrics are relatively stable over time such as when the time-domain channel property (TDCP) or spatial relationships between uplink and downlink signals / channels indicate slowly changing channel conditions.
[0010] The UE may be configured with multiple transmission occasions (e.g., multiple symbols / slots) for transmitting UCI. The UE may be configured to transmit UCI in the multiple transmission occasions based on the priority' rules determining the transmission order. For example, ACK / NACKmay be transmitted before SR and CSI, SR may be transmitted before CSI. When CSI is scheduled for multiple transmission occasions, a priority order may be applied to the CSI. For example, a priority associated with the CSI report may be based on whether the CSI is delay tolerant. The CSI may be measured CSI or predicted CSI. Measured CSI may not be delay-tolerant and have a higher priority. Predicted CSI may be delay -tolerant. Accordingly, measured CSI may be transmitted in an initial UCI transmission occasion and predicted CSI may be transmitted later in subsequent UCI transmission occasion(s) of the multiple UCI transmission occasions. In some aspects, the priority of the predicted CSI may be based on an empirical error for the predicted CSI (e.g., higher error having a lower priority), a time stamp associated with the predicted CSI (e g., older predicted CSI having a higher priority than newer predicted CSI), a time behavior of the CSI report (e.g., aperiodic CSI report having a higher priority than periodic CSI report), and / or the type of metrics included in the CSI report (e.g., reference signal received power (RSRP) and / or signal to interference plus noise ratio (SINR) having a higher priority).
[0011] According to some aspects, a UE receives, from a network entity, a configuration for a first type of uplink control information, UCI, associated with a single transmission occasion and a second type of UCI associated with a plurality of transmission occasions. The UE transmits, to the network entity, at least one of the first type of UCI or the second type of UCI.
[0012] According to some aspects, a network entity transmits, to a UE, a configuration for a first type of uplink control information, UCI, associated with a single transmission occasion and a second type of UCI associated with a plurality of transmission occasions. The network entity receives, from the UE, at least one of the first type of UCI or the second type of UCI.
[0013] Technical benefits of the present disclosure include increasing the probability of a UE transmitting UCI to a network entity and aligning UCI resources with the requirements of time delay tolerant UCI reports.BRIEF DESCRIPTION OF THE DRAWINGS

[0028] FIG. 1 illustrates a diagram 100 of a wireless communications system associated with a plurality of cells 190. The wireless communications system includes user equipments (UEs) 102 and base stations / network entities 104. Some base stations may include an aggregated base station architecture and other base stations may include a disaggregated base station architecture. The aggregated base station architecture utilizes a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node. A disaggregated base station architecture utilizes a protocol stack that is physically or logically distributed among two or more units (e.g., radio unit (RU) 106, distributed unit (DU) 108, central unit (CU) 110). For example, a CU 110 is implemented within a RAN node, and one or more DUs 108 may be co-located with the CU 110, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs 108 may be implemented to communicate with one or more RUs 106. Any of the RU 106, the DU 108 and the CU 110 can be implemented as virtual units, such as a virtual radio unit (VRU), a virtual distributed unit (VDU), or a virtual central unit (VCU). The base station / network entity 104 (e.g., an aggregated base station or disaggregated units of the base station, such as the RU 106 or the DU 108), may be referred to as a transmission reception point (TRP).
[0029] Operations of the base station 104 and / or network designs may be based on aggregation characteristics of base station functionality. For example, disaggregated base station architectures are utilized in an integrated access backhaul (IAB) network, an open-radio access network (O-RAN) network, or a virtualized radio access network (vRAN), which may also be referred to a cloud radio access network (C- RAN). Disaggregation may include distributing functionality across the two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network designs. The various units of the disaggregated base station architecture, or the disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit. For example, the base stations 104d, 104e and / or the RUs 106a, 106b, 106c, 106d may communicate with the UEs 102a, 102b, 102c, 102d, and / or 102s via one or moreradio frequency (RF) access links based on a Uu interface. In examples, multiple RUs 106 and / or base stations 104 may simultaneously serve the UEs 102, such as by intracell and / or inter-cell access links between the UEs 102 and the RUs 106 / base stations 104.
[0030] The RU 106, the DU 108, and the CU 110 may include (or may be coupled to) one or more interfaces configured to transmit or receive information / signals via a wired or wireless transmission medium. For example, a wired interface can be configured to transmit or receive the information / signals over a wired transmission medium, such as via the fronthaul link 160 between the RU 106d and the baseband unit (BBU) 112 of the base station 104d associated with the cell 190d. The BBU 112 includes aDU 108 and aCU 110, which may also have awired interface (e.g., midhaul link) configured between the DU 108 and the CU 110 to transmit or receive the information / signals between the DU 108 and the CU 110. In further examples, a wireless interface, which may include a receiver, a transmitter, or a transceiver, such as an RF transceiver, configured to transmit and / or receive the information / signals via the wireless transmission medium, such as for information communicated between the RU 106a of the cell 190a and the base station 104e of the cell 190e via cross-cell communication beams 136-138 of the RU 106a and the base station 104e.
[0031] The RUs 106 may be configured to implement lower layer functionality. For example, the RU 106 is controlled by the DU 108 and may correspond to a logical node that hosts RF processing functions, or lower layer PHY functionality, such as execution of fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc. The functionality of the RU 106 may be based on the functional split, such as a functional split of lower layers.
[0032] The RUs 106 may transmit or receive over-the-air (OTA) communication with one or more UEs 102. For example, the RU 106b of the cell 190b communicates with the UE 102b of the cell 190b via a first set of communication beams 132 of the RU 106b and a second set of communication beams 134b of the UE 102b, which may correspond to inter-cell communication beams or, in some examples, cross-cell communication beams. For instance, the UE 102b of the cell 190b may communicate with the RU 106a of the cell 190a via a third set of communication beams 134a of the UE 102b and a fourth set of communication beams 136 of the RU 106a. DUs 108 cancontrol both real-time and non-real-time features of control plane and user plane communications of the RUs 106.
[0033] Any combination of the RU 106, the DU 108, and the CU 110, or reference thereto individually, may correspond to a base station 104. Thus, the base station 104 may include at least one of the RU 106, the DU 108, or the CU 110. The base stations 104 provide the UEs 102 with access to a core network. The base stations 104 may relay communications between the UEs 102 and the core network (not shown). The base stations 104 may be associated with macrocells for higher-power cellular base stations and / or small cells for lower-power cellular base stations. For example, the cell 190e may correspond to a macrocell, whereas the cells 190a-190d may correspond to small cells. Small cells include femtocells, picocells, microcells, etc. A network that includes at least one macrocell and at least one small cell may be referred to as a “heterogeneous network.”
[0034] Transmissions from a UE 102 to a base station 104 / RU 106 are referred to as uplink (UL) transmissions, whereas transmissions from the base station 104 / RU 106 to the UE 102 are referred to as downlink (DL) transmissions. Uplink transmissions may also be referred to as reverse link transmissions and downlink transmissions may also be referred to as forward link transmissions. For example, the RU 106d utilizes antennas of the base station 104d of cell 190d to transmit a downlink / forward link communication to the UE 102d or receive an uplink / reverse link communication from the UE 102d based on the Uu interface associated with the access link between the UE 102d and the base station 104d / RU 106d.
[0035] Communication links between the UEs 102 and the base stations 104 / RUs 106 may be based on multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be associated with one or more carriers. The UEs 102 and the base stations 104 / RUs 106 may utilize a spectrum bandwidth of Y MHz (e.g., 5, 10, 15, 20, 100, 400, 800, 1600, 2000, etc. MHz) per carrier allocated in a earner aggregation of up to a total of Yx MHz, where x component carriers (CCs) are used for communication in each of the uplink and downlink directions. The carriers may or may not be adjacent to each other along a frequency spectrum. In examples, uplink and downlink carriers may be allocated in an asymmetric manner, with more or fewer carriers allocated to either the uplink or the downlink. A primary component earnerand one or more secondary component carriers may be included in the component carriers. The primary component carrier may be associated with a primary cell (PCell) and a secondary component carrier may be associated with a secondary cell (SCell).
[0036] Some UEs 102, such as the UEs 102a and 102s, may perform device-to-device (D2D) communications over sidelink. For example, a sidelink communi cation / D2D link utilizes a spectrum for a wireless wide area network (WWAN) associated with uplink and downlink communications. Such sidelink / D2D communication may be performed through various wireless communications systems, such as wireless fidelity (Wi-Fi) systems, Bluetooth systems, Long Term Evolution (LTE) systems, New Radio (NR) systems, etc.
[0037] The UEs 102 and the base stations 104 / RUs 106 may each include a plurality of antennas. The plurality of antennas may correspond to antenna elements, antenna panels, and / or antenna arrays that may facilitate beamforming operations. For example, the RU 106b transmits a downlink beamformed signal based on a first set of communication beams 132 to the UE 102b in one or more transmit directions of the RU 106b. The UE 102b may receive the downlink beamformed signal based on a second set of communication beams 134b from the RU 106b in one or more receive directions of the UE 102b. In a further example, the UE 102b may also transmit an uplink beamformed signal (e.g., sounding reference signal (SRS)) to the RU 106b based on the second set of communication beams 134b in one or more transmit directions of the UE 102b. The RU 106b may receive the uplink beamformed signal from the UE 102b in one or more receive directions of the RU 106b. The UE 102b may perform beam training to determine the best receive and transmit directions for the beamformed signals. The transmit and receive directions for the UEs 102 and the base stations 104 / RUs 106 may or may not be the same.
[0038] In further examples, beamformed signals may be communicated between a first base station / RU 106a and a second base station 104e. For instance, the base station 104e of the cell 190e may transmit a beamformed signal to the RU 106a based on the communication beams 138 in one or more transmit directions of the base station 104e. The RU 106a may receive the beamformed signal from the base station 104e of the cell 190e based on the RU communication beams 136 in one or more receive directions of the RU 106a. In further examples, the base station 104e transmits a downlink beamformed signal to the UE 102e based on the communication beams 138in one or more transmit directions of the base station 104e. The UE 102e receives the downlink beamformed signal from the base station 104e based on UE communication beams 130 in one or more receive directions of the UE 102e. The UE 102e may also transmit an uplink beamformed signal to the base station 104e based on the UE communication beams 130 in one or more transmit directions of the UE 102e, such that the base station 104e may receive the uplink beamformed signal from the UE 102e in one or more receive directions of the base station 104e.
[0039] The base station 104 may include and / or be referred to as a network entity. That is, “network entity” may refer to the base station 104 or at least one unit of the base station 104, such as the RU 106, the DU 108, and / or the CU 110. The base station 104 may also include and / or be referred to as a next generation evolved Node B (ng-eNB), a next generation NB (gNB), an evolved NB (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a TRP, a network node, network equipment, or other related terminology. The base station 104 or an entity at the base station 104 can be implemented as an IAB node, a relay node, a sidelink node, an aggregated (monolithic) base station, or a disaggregated base station including one or more RUs 106, DUs 108, and / or CUs 110. A set of aggregated or disaggregated base stations may be referred to as a next generation-radio access network (NG-RAN). In some examples, the UE 102a operates in dual connectivity (DC) with the base station 104e and the base station / RU 106a. In such cases, the base station 104e can be a master node and the base station / RU 160a can be a secondary node.
[0040] Still referring to FIG. 1, in certain aspects, any of the UEs 102 may include a multiple UCI transmission occasion (TO) component 140 configured to receive, from a network entity, a configuration for a first type of UCI associated with a single transmission occasion and a second type of UCI associated with a plurality of transmission occasions. The multiple UCI TO component 140 is further configured to transmit, to the network entity, at least one of the first type of UCI in the single transmission occasion or the second type of UCI in one or more of the plurality of transmission occasions.
[0041] In certain aspects, any of the base stations 104 or a network entity of the base stations 104 may include a multiple UCI TO configuration component 150 configured to configured to transmit, to a UE, a configuration for a first type of UCI associatedwith a single transmission occasion and a second type of CSI associated with a plurality of transmission occasions. The multiple UCI TO configuration component 150 is further configured to receive, from the UE, at least one of the first type of UCI or the second type of UCI.
[0042] Accordingly, FIG. 1 describes a wireless communication system that may be implemented in connection with aspects of one or more other figures described herein. Further, although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as 5G-Advanced and future versions, LTE, LTE-advanced (LTE-A), and other wireless technologies, such as 6G.
[0043] FIG. 2 illustrates a timing diagram 200 of multiple UCI transmission occasions 206 referenced to a reference transmission 204 according to an embodiment. In some aspects, a network entity may transmit a reference transmission 204 (e.g. , a scheduling transmission, a reference signal transmission, or other suitable transmission). In some aspects, the reference transmission 204 may be associated with a reference slot. Multiple UCI transmission occasions 206 may be scheduled based on an offset 211 from the reference transmission 204. For example, first transmission occasion 206a may be scheduled based on an offset 211a from the reference transmission 204. Second transmission occasion 206b may be scheduled based on an offset 21 lb from the reference transmission 204. Although FIG. 2 illustrates two transmission occasions 206 for UCI, the present disclosure is not so limited and any number of UCI transmission occasions 206 may be scheduled. In some aspects, the offset 211 may be based on a number of slots, a number of symbols, a number of milliseconds, or any suitable time period.
[0044] In some aspects, the UE may receive, from a network entity, a configuration for a first type of UCI 209a (e.g., delay-intolerant UCI or higher priority UCI) associated with a single transmission occasion (e.g., first transmission occasion 206a) and a second type of UCI 209b (e.g., delay-tolerant UCI or lower priority UCI) associated with multiple transmission occasions (e.g., first transmission occasion 206a and second transmission occasion 206b). The UE may transmit, to the network entity the first type of UCI (e.g., UCI 209a) in the first transmission occasion 206a and transmit the second type of UCI (e.g., UCI 209b) in the second transmission occasion 206b.
[0045] In some aspects, the timing diagram 200 may illustrate different UCI transmission scenarios. In a first scenario, a conflict may exist at first transmission occasion 206a where another uplink / downlink transmission that has higher priority than both the first and second UCI types 209 is transmitted. In this first scenario, both the first and second UCI types 209 are not transmitted in the first transmission occasion 206a and both the first and second UCI types 209 dropped at the first transmission occasion 206a but the second type of UCI 209b is buffered and transmitted at the second transmission occasion 206b. In a second scenario, a conflict exists between the first type of UCI 209a and the second type of UCI 209b. In this second scenario, the first type of UCI 209a is transmitted in the first transmission occasion 206a and the second type of UCI 209b is buffered and transmitted in the second transmission occasion 206b. In the third scenario, no conflict exists between the first ty pe of UCI 209a and the second type of UCI 209b (e.g., such as when there are sufficient resources in the first transmission occasion 206a to transmit both the first type of UCI 209a and the second type of UCI 209b in the first transmission occasion 206a), the UE may transmit both the first type of UCI 209a and the second type of UCI 209b in the first transmission occasion 206a and optionally transmit the second type of UCI 209b in the second transmission occasion 206b as well.
[0046] In some aspects, the UE may transmit the first type of UCI 209a and / or the second type of UCI 209b periodically, semi-persistently, or aperiodically.
[0047] FIG. 3 illustrates a timing diagram 300 of multiple UCI transmission occasions 306 referenced to a scheduling slot 304 according to an embodiment. In some aspects, a network entity may transmit downlink control information DCI 308 (e.g., on a physical downlink control channel (PDCCH)) in scheduling slot K 304. The DCI 308 may indicate scheduled resources (e.g., time resources, frequency resources, spatial resources) for the UE to transmit the UCI 309. The DCI 308 may schedule multiple transmission occasions for the UE to transmit the UCI 309. For example, the DCI 308 may schedule first transmission occasion slot 306a and second transmission occasion slot 306b. In some aspects, the scheduling slot 304 may be associated with a radio resource control (RRC) message configuring resources for uplink transmissions including the multiple transmission occasions for the UCI. In some other aspects, the scheduling slot 304 may be associated with a medium access control (MAC) control element for activating the multiple transmission occasions for the UCI.
[0048] In some aspects, the UCI transmission occasion slots 306 may be scheduled based on an offset 311 from the scheduling slot K 304. For example, first transmission occasion slot 306a may be scheduled based on an offset 311a from the scheduling slot K 304. The offset 311a may be indicated as X number of slots. For example, the scheduling slot K 304 may be in slot K and the DCI 308 may indicate an offset 31 la as X slots such that first transmission occasion slot 306a is located at slot K+X. The DCI 308 may indicate an offset 311b as Y slots such that second transmission occasion slot 306b is located at slot K+Y. Additionally or alternatively, the offset 311 may be indicated as a slot offset and a number of the transmission occasion slots 306. For example, the offset 311a may be indicated as slot K+Z and each subsequent transmission occasion is based on a multiple of Z (e.g., offset 31 lb is indicated as slot K+2Z).
[0049] Although FIG. 3 illustrates two UCI transmission occasion slots 306, the present disclosure is not so limited and any number of UCI transmission occasion slots 306 may be scheduled.
[0050] In some aspects, the UE may transmit, to the network entity, the first type of UCI 309a (associated with a single transmission occasion) in the first transmission occasion slot 306a and transmit the second type of UCI 309b (associated with multiple transmission occasions) in the second transmission occasion slot 306b. The UE may transmit the UCI 309 in one or more symbols of the transmission occasion slots 306.
[0051] In some aspects, the timing diagram 300 may illustrate different UCI transmission scenarios. In a first scenario, a conflict may exist at first transmission occasion 306a where another uplink / downlink transmission that has higher priority than both the first and second UCI types 309 is transmitted. In this first scenario, both the first and second UCI types 309 are not transmitted in the first transmission occasion 306a and both the first and second UCI types 309 dropped at the first transmission occasion 306a but the second type of UCI 309b is buffered and transmitted at the second transmission occasion 306b. In a second scenario, a conflict exists between the first type of UCI 309a and the second type of UCI 309b. In this second scenario, the first type of UCI 309a is transmitted in the first transmission occasion 306a and the second type of UCI 309b is buffered and transmitted in the second transmission occasion 306b. In the third scenario, no conflict exists between the first ty pe of UCI 309a and the second type of UCI 309b (e.g., such as when there are sufficient resources in thefirst transmission occasion 306a to transmit both the first type of UCI 309a and the second type of UCI 309b in the first transmission occasion 306a), the UE may transmit both the first type of UCI 309a and the second type of UCI 309b in the first transmission occasion 306a and optionally transmit the second type of UCI 309b in the second transmission occasion 306b as well.
[0052] FIG. 4 illustrates a timing diagram 400 of multiple UCI transmission occasions 406 referenced to a reference signal (RS) transmission slot 404 according to an embodiment. The embodiment of FIG. 4 is similar to the embodiment of FIG. 3. In FIG. 3, the UCI transmission occasions 306 are scheduled with reference to a scheduling slot 304 that includes DCI 308 for scheduling the UCI transmission occasions 306. In FIG. 4, the UCI transmission occasions 406 are scheduled with reference to a RS transmission slot 404 that includes a RS (e.g., channel state information reference signal (CSI-RS) 408. The UE may measure the CSI-RS 408 and provide CSI feedback (e.g., a CSI report) to the network entity via UCI 409 transmitted in one or more of the UCI transmission occasions 406.
[0053] In some aspects, the UCI transmission occasion slots 406 may be scheduled based on an offset 411 from the RS transmission slot L 404. For example, first transmission occasion slot 406a may be scheduled based on an offset 411a from the RS transmission slot L 404. The offset 41 la may be indicated as X number of slots from the RS transmission slot L 404. For example, the RS transmission slot L 404 may be in slot L and the first transmission occasion slot 406a is located at slot L+X. The second transmission occasion slot 406b is located at slot L+Y.
[0054] Although FIG. 4 illustrates two UCI transmission occasion slots 406 referenced to the RS slot L 404, the present disclosure is not so limited and any number of UCI transmission occasion slots 406 may be scheduled. The RS transmission slot L 404 may include any type of reference signal. For example, RS transmission slot L 404 may include a channel state information-reference signal (CSI-RS), a synchronization signal block (SSB), a demodulation reference signal (DMRS), a tracking reference signal (TRS), a phase tracking reference signal (PTRS), or any suitable reference signal).
[0055] In some aspects, the UE may transmit, to the network entity, the first type of UCI 409a in the first transmission occasion slot 406a and transmit the second type of UCI 409b in the second transmission occasion slot 406b. In some aspects, the first type ofUCI 409 may be a delay -intolerant and the second type of UCI 409 may be a delay- tolerant. For example, the delay-intolerant UCI 409 may include measured CSI that changes rapidly, the network entity may use real-time CSI 409 to determine the conditions of the channel and adapt downlink communications accordingly. The delay-tolerant UCI 409 may include predicted CSI that may be tolerant of delays in the UE transmitting the CSI to the network entity. Predicted CSI may be delay tolerant based on the prediction term being relatively long (e.g., 20 ms).
[0056] In some aspects, if the first type of UCI 409a is not transmitted in the first transmission occasion 406a, the UE discards the UCI 409a. If the second type of UCI 409a is not transmitted in the first (e.g., initial) occasion slot 406a, the UE may buffer the UCI 409a and transmit the UCI 409a in a later transmission occasion such as second occasion slot 406b.
[0057] In some aspects, the timing diagram 400 may illustrate different UCI transmission scenarios. In a first scenario, a conflict may exist at first transmission occasion 406a where another uplink / downlink transmission that has higher priority than both the first and second UCI types 409 is transmitted. In this first scenario, both the first and second UCI types 409 are not transmitted in the first transmission occasion 406a and both the first and second UCI types 409 dropped at the first transmission occasion 406a but the second type of UCI 409b is buffered and transmitted at the second transmission occasion 406b. In a second scenario, a conflict exists between the first type of UCI 409a and the second type of UCI 409b. In this second scenario, the first type of UCI 409a is transmitted in the first transmission occasion 406a and the second type of UCI 409b is buffered and transmitted in the second transmission occasion 406b. In the third scenario, no conflict exists between the first type of UCI 409a and the second type of UCI 409b (e.g., such as when there are sufficient resources in the first transmission occasion 406a to transmit both the first type of UCI 409a and the second type of UCI 409b in the first transmission occasion 406a), the UE may transmit both the first type of UCI 409a and the second type of UCI 409b in the first transmission occasion 406a and optionally transmit the second type of UCI 409b in the second transmission occasion 406b as well.
[0058] FIG. 5 illustrates a timing diagram 500 of multiple UCI transmission occasions 509 referenced to a reference transmission 504 according to an embodiment. In FIG. 5, the transmission occasions 509a and 509b may be associated with symbols withina first / second occasion slot 506. In some aspects, the reference transmission may be any suitable type of transmission from the network entity.
[0059] In some aspects, the UCI transmission occasions 509 may be scheduled based on an offset 511 from the reference transmission 504. For example, first transmission occasion 509a may be one or more symbols (e.g., starting symbol 3) scheduled based on an offset 51 la from the reference transmission 504. Second transmission occasion 509b may be one or more symbols (e.g., starting symbol 10) scheduled based on an offset 511b from the reference transmission 504. The offsets 511a and 511b may be indicated as a number of slots, symbols, or milliseconds from the reference transmission 504. Additionally or alternatively, the second occasion 509b may be indicated as a number of symbols or milliseconds referenced to the first occasion 509a. Although FIG. 5 illustrates two UCI transmission occasion symbols 509 referenced to the reference transmission 504, the present disclosure is not so limited and any number of UCI transmission occasion symbols 509 may be scheduled.
[0060] FIG. 6A illustrates a timing diagram 600 of a schedule for reporting multiple types of UCI 609 according to an embodiment. At first transmission occasion T1 a first type of UCI 609a and a second type of UCI 609b are scheduled for transmission. However, a conflict may exist at the first transmission occasion T1 preventing the transmission of both the first type of UCI 609a and the second type of UCI 609b. The conflict may be based on different priorities between the first type of UCI 609a and the second type of UCI 609b, a payload capacity of the UCI 609, the amount of resources scheduled for UCI 609 at Tl, a processing capability of the UE (e.g., a number of occupied CSI processing units (CPUs)), or other type of conflict. Based on the conflict at the first transmission occasion Tl, the UE may transmit the first type of UCI 609a (e.g., delay- intolerant UCI or higher priority UCI) and refrain from transmitting the second type of UCI 609b (e.g., delay-tolerant UCI or lower priority UCI). The UE may buffer (e.g., store) the second type of UCI 609b (e.g., delay-tolerant UCI or lower priority UCI) for transmission at second transmission occasion T2.
[0061] FIG. 6B illustrates a timing diagram 601 of transmission of multiple types of UCI 609 according to an embodiment. As described with reference to FIG. 6A, based on the conflict at the first transmission occasion Tl, the UE may transmit the first type of UCI 609a at the first transmission occasion Tl and buffer the second type of UCI 609b. The UE may buffer the second type of UCI 609b until second transmissionoccasion T2 and transmit the second type of UCI 609b at T2 provided that another conflict does not exist preventing the transmission of the second type of UCI 609b. If another conflict exists, the UE may again buffer the second type of UCI 609b until a later transmission occasion. If another conflict exists causing the UE to refrain from transmitting the first type of UCI 609a and the second type of UCI 609b, the UE discards the first type of UCI 609a and buffers the second type of UCI 609b until the second transmission occasion T2.
[0062] FIG. 7 illustrates a diagram 700 of resource table 754 indicating resources for multiple UCI transmission occasions according to an embodiment. In some aspects, the network entity may transmit, to the UE, an indication of resources (e.g., time resources, frequency resources, spatial resources) for the multiple UCI transmission occasions. In some aspects, the UE may be configured (e.g., via radio resource control (RRC) signaling) with resource table 754 indicating the resources. For example, resource table 754 may include columns indicating offsets corresponding to transmission occasions. The offsets may be offsets from a reference slot, a reference signal (e.g., CSI-RS) transmission, or a scheduling message (e.g., RRC, MAC CE, or DCI) transmission. For example, UCI initial transmission occasion resources 752a may indicate offsets for the initial (e.g., first) transmission occasion. UCI second transmission occasion resources 752b may indicate offsets for the second transmission occasion. UCI last transmission occasion resources 752n may indicate offsets for the last transmission occasion.
[0063] In some aspects, the UCI occasion resources 752 may be indicated by slot numbers and / or symbol numbers. Each row of resource table 754 may correspond to a UCI resource index 750. In some aspects, the network entity may transmit, to the UE, DCI indicating an index to the row of resource table 754 that the UE shall use to schedule UCI transmissions.
[0064] FIG. 8 is a signaling diagram 800 illustrating communications between a UE 102 and a network entity 104 for multiple UCI transmission occasions. The UE 102 may optionally transmit 805, to the network entity 104, UE capabilities indicating supported configurations for multiple UCI transmission occasions. The UE 102 may report at least one of the following UE capabilities: support for reporting UCI associated with multiple transmission occasions; types of UCI for multiple transmission occasions; minimum or maximum number of transmission occasions; abuffer size for storing the UCI; support for CSI prediction; and / or a number of supported CSI processing units (CPUs).
[0065] The network entity 104 transmits 810, to the UE 102, a configuration for multiple UCI transmission occasions. The network entity 104 may transmit 810, to the UE 102, the configuration by RRC signaling (e.g.,RRCReconfiguration or CSI-ReportConfig), MAC-CE, or DCI. The configuration may include: an indication of resources associated with the multiple transmission occasions; an index to a UCI resource table (e.g., resource table 754 of FIG. 7) indicating resources associated with the multiple transmission occasions; a number of multiple transmission occasions; a time domain resource allocation indicating at least one of: one or more slots for the transmission occasions; one or more symbols for the transmission occasions; offset(s) from a reference transmission, a scheduling slot, or a reference signal (e.g., CSI-RS) slot; a number of slots or symbols between adjacent transmission occasions; a configuration for CSI-RS as a channel measurement resource (CMR) and interference measurement resource (IMR), and / or parameters related to the priority of each transmission occasion.
[0066] In some aspects, for semi-persistent CSI reporting or aperiodic CSI reporting, the network entity 104 may optionally transmit 820 a MAC CE or DCI activating or triggering the UCI transmission occasions(s) (e.g., UCI transmissions occasions including CSI report(s)). In some aspects, the network entity 104 may optionally transmit 820 a MAC CE or DCI activating or triggering a CSI report that is configured with multiple UCI transmission occasions.
[0067] In some aspects, the network entity 104 transmits 830 the CSI-RSs on CSI-RS resources in a CSI-RS resource set for channel measurement. Additionally, the network entity may transmit CSI-RS resources for interference measurement or channel state information-interference measurement (CSI-IM) resources. The UE 102 may measure CSI (e.g., a rank indicator (RI), a precoder matrix indicator (PMI), a channel quality indicator (CQI), and a layer indicator (LI)) based on one or more CSI- RSs. In some aspects, the UE 102 may predict CSI for a future term (e.g., a number of slots / milliseconds in the future). For example, the UE 102 may use a machine learning function to predict CSI. In some aspects, the predicted CSI may be delay tolerant in the UE 102 transmitting the predicted CSI to the network entity 104. Predicted CSI may be delay-tolerant based on the prediction term being relativelylong (e.g., 20 ms). In some aspects, measured CSI may be delay-intolerant. For example, when the measured CSI changes rapidly, the network entity 104 may use real-time to determine the conditions of the channel and adapt downlink communications accordingly. In some aspects, measured CSI may be delay-tolerant when the measured channel metrics are relatively stable over time such as when the time-domain channel property (TDCP) or spatial relationships between uplink and downlink signals / channels indicate slowly changing channel conditions.
[0068] As described with reference to FIGs. 2-7, the UE 102 may be configured with multiple transmission occasions (e.g., multiple symbols, slots, milliseconds) for transmitting UCI. The UE 102 may be configured to transmit 840 UCI including CSI in the multiple transmission occasions based on priority rules for determining the transmission order. For example, UCI including ACK / NACK may be transmitted 840 before SR and CSI, SR may be transmitted 840 before CSI. When CSI is scheduled for multiple transmission occasions, a priority order may be applied to the CSI. For example, a priority associated with the CSI report may be based on whether the CSI is delay tolerant. The CSI may be measured CSI or predicted CSI. Predicted CSI may be delay-tolerant. Measured CSI may be delay-intolerant and have a higher priority than predicted CSI. Accordingly, measured CSI may be transmitted 840a in an initial UCI transmission occasion and predicted CSI may be transmitted 840b... 840x later in subsequent UCI transmission occasion(s) of the multiple UCI transmission occasions.
[0069] In some aspects, the priority of the predicted CSI may be based on a term of the predicted CSI (e.g., a shorter term having a higher priority than a longer term); an empirical error for the predicted CSI (e.g., higher error having a lower priority), an average empirical error for a machine learning function associated with the predicted CSI (e.g., higher error having a lower priority); an identifier of the machine learning function associated with the predicted CSI; a time stamp associated with the predicted CSI (e.g., older predicted CSI having a higher priority than newer predicted CSI), a relative time of each transmission occasion of the multiple transmission occasions, a number of the transmission occasions, a number of transmission occasions remaining in the multiple transmission occasions, a weighting value associated with the number of transmission occasions remaining in the multiple transmission occasions, an order index of each of the multiple transmission occasions, a time behavior of the CSI report(e.g., aperiodic CSI report having a higher priority than periodic CSI report), and / or the type of metrics included in the CSI report (e.g., reference signal received power (RSRP) and / or signal to interference plus noise ratio (SINR) having a higher priority).
[0070] In some aspects, on the n-th configured / scheduled UCI transmission occasion, the CSI report is associated with a priority value based on Equation (1) below:
[0071] Priicsity, k, c, s, n, P, t, F) = 2 - Nceus- Ms- y + Nceas■ Ms■ k + Ms■ c + s + X ■ ^occasions ~ n) + Y ■ P+Z' t + F ' W (1)
[0072] Where y= 0 for aperiodic CSI reports to be carried on a PUSCH, ^=1 for semi- persistent CSI reports to be earned on a PUSCH, y=l for semi-persistent CSI reports to be carried on a PUCCH and =3 for periodic CSI reports to be carried on a PUCCH; k=Q for CSI reports carrying Ll-RSRP or Ll-SINR and k=l for CSI reports not carrying Ll-RSRP or Ll-SINR; c is the serving cell index; Nce((sis the value of the higher layer parameter maxNrofServmgCells,' s is the reportConfigID Msis the value of the higher layer parameter maxNrofCSI-ReportConflgurations; n is the order index of the scheduled / configured transmission occasion; Noccasionsis the total number of scheduled / configured transmission occasions; X is a fixed value defined in a standards document or signaled by the network entity 104; P indicates whether the CSI report contains only predicted CSI (e.g., P=1 when the CSI report contains only predicted CSI and P=0 when the CSI report contains at least one measured CSI); Y is a fixed value pre-defined in a technical specification or configured by the network entity 104; t is the time stamp associated with the predicted CSI contained in the CSI report (e.g., when P=0, t=0 when P=1 and the CSI report contains multiple predicted CSI), t is determined by the predicted CSI associated with the soonest (e.g., earliest) future time stamp; Z is a fixed value pre-defined in a technical specification or configured by the network entity 104; F is priority order of the prediction function associated with the predicted CSI contained in the CSI report (e.g., F=0 when P=0).' and W is a fixed value pre-defined in a technical specification or configured by the network entity 104.
[0073] In some aspects, the network entity 104 may identify which CSI report is transmitted by the UE 102 in each UCI transmission occasion. The UE 102 and the network entity 102 may use a common set of rules to determine the CSI report priority. For example, the common set of rules may be defined in a standards document or signaled by the network entity 104. In some aspects, the UE may determine the CSI report priority (e.g., based on a CSI prediction function) and indicate to the networkentity 104 which CSI report(s) are included in the UCI transmission occasions. For example, the CSI report may include codepoint(s) indicating the CSI prediction function identifier. The UE 102 may transmit 840a UCI at a first transmission occasion based on the priority of the UCI. For example, the UE 102 may transmit a first type of UCI (e.g. , delay-intolerant UCI including measured CSI) or a second type of UCI (e.g., delay-tolerant UCI including predicted CSI) scheduled for transmission. Based on a conflict preventing the UE 102 from transmitting 840 both the first and second types of UCI in the first transmission occasion, the UE 102 may refrain from transmitting the second type of UCI, transmit 840a the first type of UCI in the first transmission occasion, and buffer (e.g., store) the second type of UCI. The UE 102 may buffer the second type of UCI until the second transmission occasion and transmit 840b the second type of UCI provided that another conflict does not exist preventing the transmission of the second type of UCI. If another conflict exists, the UE 102 may again buffer the second type of UCI until a later transmission occasion and transmit 840x the second type of UCI at the later transmission occasion. In some aspects, the UE 102 may transmit 840 the second type of UCI in multiple transmission occasions in order to increase the probability of the network entity 104 correctly decoding the UCI. For example, the UE 102 may transmit 840a the second type of UCI in a first transmission occasion and repeat the transmission 840b of the second type of UCI in a second transmission occasion and / or subsequent transmission occasions. The second type of UCI may include an indicator (e.g., one or more codepoints) for the contents of the second ty pe of UCI. In some aspects, if the UE 102 is unable to transmit 840 the second type of UCI in the multiple transmission occasions, the network entity 104 may transmit, to the UE 102, an indicator of dedicated resources for the UE 102 to transmit the second type of UCI.
[0074] FIGs. 2-8 illustrate multiple transmission occasions for UCI. FIGs. 9-10 show methods for implementing one or more aspects of FIGs. 2-8. In particular, FIG. 9 shows an implementation by the UE 102 of the one or more aspects of FIGs. 2-8. FIG. 10 shows an implementation by the network entity 104 of the one or more aspects of FIGs. 2-8.

With reference to FIGs. 1-8, the method may be performed by one or more network entities 104, which may correspond to a base station or a unit of the base station, such as the RU 106, the DU 108, and / or the CU 110. In embodiments, a network entity optionally receives 1005, from a UE, UE capability on supported configurations for multiple UCI transmission occasions.

For example, referring to FIG. 8, the network entity 104 optionally transmits 820, to the UE 102, a MAC-CE or DCI activating / triggering the multiple UCI transmission occasions.
[0084] In embodiments, the network entity transmits 1030, to the UE, CSI-RS / CSI-IM on the configured CMR / IMR resources. For example, referring to FIG. 8, the network entity 104 transmits 830, to the UE 102, CSI-RS / CSI-IM on the configured CMR / IMR resources.
[0085] In embodiments, the network entity receives 1040, from the UE, at least one of the first type of UCI in the single transmission occasion or the second type of UCI in one or more of the plurality of transmission occasions. For example, referring to FIG. 8, the network entity 104, receives 840, from the UE 102, UCI in one or more of the plurality of transmission occasions.
[0086] A UE apparatus 1102, as described in FIG. 11, may perform the method of flowchart 900. The one or more network entities 104, as described in FIG. 12, may perform the method of flowchart 1000.
[0087] FIG. 11 is a diagram 1100 illustrating an example of a hardware implementation for a UE apparatus 1102. The UE apparatus 1102 may be the UE 102, a component of the UE 102, or may implement UE functionality. The UE apparatus 1102 may include an application processor 1106, which may have on-chip memory 1106’. In examples, the application processor 1106 may be coupled to a secure digital (SD) card 1108 and / or a display 1110. The application processor 1106 may also be coupled to a sensor(s) module 1112, a power supply 1114, an additional module of memory 1116, a camera 1118, and / or other related components.
[0088] The UE apparatus 1102 may further include a wireless baseband processor 1126, which may be referred to as a modem. The wireless baseband processor 1126 may have on-chip memory 1126'. Along with, and similar to, the application processor 1106, the wireless baseband processor 1126 may also be coupled to the sensor(s) module 1112, the power supply 1114, the additional module of memory 1116, the camera 1118, and / or other related components. The wireless baseband processor 1126 may be additionally coupled to one or more subscriber identity module (SIM) card(s) 1120 and / or one or more transceivers 1130 (e.g., wireless RF transceivers).

[0091] As discussed in FIG. 1 and implemented with respect to FIG. 9, the multiple UCI transmission occasions (TO) component 140 is configured to receive, from a network entity, a configuration for a first type of UCI associated with a single transmission occasion and a second type of UCI associated with a plurality of transmission occasions. The multiple UCI TO component 140 is further configured to transmit, to the network entity, at least one of the first type of UCI in the single transmission occasion or the second type of UCI in one or more of the plurality of transmission occasions.
[0092] The multiple UCI TO component 140 may be within the application processor 1106 (e.g., at 140a), the wireless baseband processor 1126 (e.g., at 140b), or both the application processor 1106 and the wireless baseband processor 1126. The multiple UCI TO component 140a-140b may be one or more hardware components specifically configured to carry out the stated processes / algorithm, implemented by one or more processors configured to perform the stated processes / algorithm, stored within a computer-readable medium for implementation by the one or more processors, or a combination thereof.
[0093] FIG. 12 is a diagram 1200 illustrating an example of a hardware implementation for one or more network entities 104. The one or more network entities 104 may be a base station, a component of a base station, or may implement base station functionality. The one or more network entities 104 may include, or may correspond to, at least one of the RU 106, the DU, 108, or the CU 110. The CU 110 may include a CU processor 1246, which may have on-chip memory 1246'. In some aspects, the CU 110 may further include an additional module of memory 1256 and / or a communications interface 1248, both of which may be coupled to the CU processor 1246. The CU 110 can communicate with the DU 108 through a midhaul link 162, such as an Fl interface between the communications interface 1248 of the CU 110 and a communications interface 1228 of the DU 108.

[0096] The on-chip memory 1206', 1226', 1246' and the additional modules of memory 1216, 1236, 1256 may each be considered a computer-readable medium I memory . Each computer-readable medium I memory may be non-transitory. Each of the processors 1206, 1226, 1246 is responsible for general processing, including execution of software stored on the computer-readable medium / memory. The software, when executed by the corresponding processor(s) 1206, 1226, 1246 causes the processor(s) 1206, 1226, 1246 to perform the various functions described herein. The computer-readable medium I memory may also be used for storing data that is manipulated by the processor(s) 1206, 1226, 1246 when executing the software. In examples, the UCI TO configuration component 150 may sit at any of the one or more network entities 104, such as at the CU 110; both the CU 110 and the DU 108; each of the CU 110, the DU 108, and the RU 106; the DU 108; both the DU 108 and the RU 106; or the RU 106.

[0099] The specific order or hierarchy of blocks in the processes and flowcharts disclosed herein is an illustration of example approaches. Hence, the specific order or hierarchy of blocks in the processes and flowcharts may be rearranged. Some blocks may also be combined or deleted. Dashed lines may indicate optional elements of the diagrams. The accompanying method claims present elements of the various blocks in an example order, and are not limited to the specific order or hierarchy presented in the claims, processes, and flowcharts.
[0100] The detailed description set forth herein describes various configurations in connection with the drawings and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough explanation of various concepts. However, these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0101] Aspects of wireless communication systems, such as telecommunication systems, are presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and are illustrated in the accompanying drawings by various blocks, components, circuits, processes, call flows, systems, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0102] An element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems-on-chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other similar hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software, which may be referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. Software shall be constmed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.
[0103] If the functionality described herein is implemented in software, the functions may be stored on, or encoded as, one or more instructions or code on a computer-readable medium, such as a non-transitory computer-readable storage medium. Computer- readable media includes computer storage media and can include a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. Storage media may be any available media that can be accessed by a computer.
[0104] Aspects, implementations, and / or use cases described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, the aspects, implementations, and / or use cases may come about via integrated chip implementations and other non-module-component based devices, such as end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / pur chasing devices, medical devices, artificial intelligence (Al)-enabled devices, machine learning (ML)-enabled devices, etc. The aspects, implementations, and / or use cases may range from chip-level or modularcomponents to non-modular or non-chip-level implementations, and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more techniques described herein.
[0105] Devices incorporating the aspects and features described herein may also include additional components and features for the implementation and practice of the claimed and described aspects and features. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes, such as hardware components, antennas, RF-chains, power amplifiers, modulators, buffers, processor(s), interleavers, adders / summers, etc. Techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc., of varying configurations.
[0106] The description herein is provided to enable a person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not limited to the aspects described herein, but are to be interpreted in view of the full scope of the present disclosure consistent with the language of the claims.
[0107] Reference to an element in the singular does not mean “one and only one” unless specifically stated, but rather “one or more.” Terms such as “if,” “when,” and “while” do not imply an immediate temporal relationship or reaction. That is, these phrases, e.g., “when,” do not imply an immediate action in response to or during the occurrence of an action, but simply imply that if a condition is met then an action will occur, but without requiring a specific or immediate time constraint for the action to occur. The terms “may”, “might”, and “can”, as used in this disclosure, often carry certain connotations. For example, “may” refers to a permissible feature that may or may not occur, “might” refers to a feature that probably occurs, and “can” refers to a capability (e.g., capable of). The phrase “For example” often carries a similar connotation to “may” and, therefore, “may” is sometimes excluded from sentences that include “for example” or other similar phrases.
[0108] Unless specifically stated otherwise, the term “some” refers to one or more. Combinations such as “at least one of A, B, or C” or “one or more of A, B, or C” include any combination of A, B, and / or C, such as A and B, A and C, B and C,or A and B and C, and may include multiples of A, multiples of B, and / or multiples of C, or may include A only, B only, or C only. Sets should be interpreted as a set of elements where the elements number one or more. Terms or articles such as “a”, “an”, and / or “the” may refer to one of an item, feature, element, etc., that the term or article precedes, or may refer to more than one of said item, feature, element, etc. that the term or article precedes. For example, the recitation “a widget” does not preclude reference to multiples of said widget, as “multiple widgets” necessarily includes “a widget”. Hence, the recitation “a widget” may be interpreted as “at least one widget” or, similarly, interpreted as “one or more widgets”.
[0109] Unless otherwise specifically indicated, ordinal terms such as “first” and “second” do not necessarily imply an order in time, sequence, numerical value, etc., but are used to distinguish between different instances of a term or phrase that follows each ordinal term.
[0110] Reference numbers, as used in the specification and figures, are sometimes cross- referenced among drawings to denote same or similar features. A feature that is exactly the same in multiple drawings may be labeled with the same reference number in the multiple drawings. A feature that is similar among the multiple drawings, but not exactly the same, may be labeled with reference numbers that have different leading numbers but have one or more of the same trailing numbers (e.g., 206, 306, 406, etc., may refer to similar features in the drawings). Hence, like numbers may refer to like actions.
[0111] Structural and functional equivalents to elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are encompassed by the claims. The words “module,” “mechanism,” “element,” “device,” and the like may not be a substitute for the word “means.” As such, no claim element is to be construed as a means plus function unless the element is expressly recited using the phrase “means for.” As used herein, the phrase “based on” shall not be construed as a reference to a closed set of information, one or more conditions, one or more factors, or the like. In other words, the phrase “based on A”, where “A” may be information, a condition, a factor, or the like, shall be construed as “based at least on A” unless specifically recited differently.
