NR may be a unified network/ system that targets to meet vastly different and sometimes conflicting performance dimensions and services. Such diverse multidimensional requirements may be driven by different services and applications. In general, NR will evolve based on third generation partnership project (3GPP) LTE-Advanced with additional potential new Radio Access Technologies (RATs) to enrich people lives with better, simple and seamless wireless connectivity solutions. NR may deliver fast, rich contents and services to wireless connectivity.
Additionally, as previously noted, the NR system operate based on a concept of slot. A PDSCH or a PUSCH may be restricted within a slot. Such restriction on PDSCH or PUSCH may still applies in high frequency carrier bands (e.g., carrier frequencies above approximately 52.6 gigahertz (GHz)). On the other hand, for a system operating at or above the approximately 52.6GHz carrier frequency, especially for Terahertz communication, a larger subcarrier spacing may be needed to combat severe phase noise. In cases where a larger subcarrier spacing, e.g., approximately 1.92 megahertz (MHz) or approximately 3.84MHz is employed, the slot duration may be relatively short. For instance, for a 1.92MHz subcarrier spacing, one slot duration may be approximately 7.8 microseconds (ps). This slot duration may not be sufficient for higher layer processing, including Medium Access Layer (MAC) and Radio Link Control (RLC), etc., because it may be too short. In order to address this issue, a next generation NodeB (gNB) may schedule the downlink (DL) or uplink (UL) data transmission across a slot boundary with long transmission duration. In other words, the slot concept may not be used when scheduling a given data transmission.
Figure 1 schematically illustrates an example of long PDSCH transmission duration, in accordance with various embodiments. Specifically, Figure 1 depicts a transmission 100 with a plurality of slots 105. A PDSCH transmission 110 may span several ones of the slots 105 as shown. In DL transmission, more DL traffic may arrive at the gNB when the gNB is still sending out DL downlink control information (DCI) or a previous PDSCH transmission. This new DL traffic may cause the gNB to send a new DL DCI to schedule a PDSCH, which may result in the delay of data transmissions. In one embodiment, the gNB may be allowed to schedule more DL resources than those required to transmit the current DL data in the buffer. Consequently, if new DL traffic arrives, the gNB may continue the PDSCH transmission for the new DL traffic on the scheduled DL resource. On the other hand, if there is no new incoming DL traffic, it may be desirable for the scheduled DL resources to be released earlier, e.g. early termination of the PDSCH transmission. In addition to the case of lacking new DL traffic, there may also exist other reasons that the gNB needs to terminate a DL transmission earlier. Figure 2 illustrates an example for which the allocated DL resources could carry 10 CBs, e.g. CBs 0-9 at 205. However, the DL transmission may be terminated only after the transmission of 6 CBs, e.g. CBs 6-9 at 210.
For the DL or UL transmission in NR, a transport block (TB) from the MAC layer may be transmitted at physical layer. For the hybrid automatic repeat request (HARQ) transmission of a giv4n DL transmission, a single HARQ-ACK bit may be reported by UE for a TB. Alternatively, if code block (CB) group (CBG) based transmission is configured, e.g. a TB is divided into n CBGs, n < N, N = 1,2, 4, 8 , a CBG may include one or multiple code block CBs. A CBG transmission indicator (CBGTI) field may be used to indicate whether a CBG is scheduled or not by a DCI. A UE may report n or N HARQ-ACK bits for the TB. One HARQ-ACK bit may be reported for each CBG. N may represent the maximum number of CBGs which may be configured by high layer. If a DCI schedules X TBs, then there may be X NDI bits in the DCI. For a system operating above 52.6GHz carrier frequency, especially for Terahertz communication, when the number of TBs or CBGs that are scheduled by a DCI is or may be large, a direct extension of the NDI or CBGTI field may result in large overhead in DCI. Various embodiments herein provide solutions for efficient indication in the DCI.
Specifically, embodiments herein relate to a detailed scheme to transmit downlink scheduling information for a carrier frequency at or above approximately 52.6GHz.
In the following descriptions, a DL or UL data transmission scheduled by a DCI may include M code block bundle (CBB)s, M CBGs, and/or M TBs. Each CBB may include one or multiple consecutive CBs. Cyclic redundancy check (CRC) may be added for each CB. However, there may not exist an additional CRC for the multiple CBs of a CB. A CBB may correspond to a MAC protocol data unit (PDU) or a TB. A separate HARQ process number (HPN) may be assigned to a CBB. A CBB may be mapped to all time/frequency resources of certain consecutive symbols. By this way, symbol alignment may be achieved for a CBB. A HARQ-ACK bit may be reported for a CBB. Alternatively, HARQ-ACK bits of multiple CBBs may be bundled into one bit to reduce the overhead of HARQ-ACK feedback.
Note that, for the sake of discussion of embodiments herein, CBB, CBG, and TB may be used inter changably.
HPN, NDI, redundancy version (RY) in a PCI
In the following embodiments, if early termination of PDSCH or PUSCH is not applied, the gNB or UE may continuously transmit the PDSCH or PUSCH in all the indicated time/frequency resources by the DCI. On the other hand, if early termination of PDSCH or PUSCH is applied, only the starting CBBs until the time of early termination may be transmitted. The remaining CBBs may be dropped.
In one embodiment of the disclosure, to schedule a downlink or uplink transmission, a DCI may indicate one or more of the following:
A start HPN which may apply to the first CBB scheduled by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for subsequent multiple CBBs scheduled by the DCI.
One NDI bit for each CBB. The number of NDI bits may need to be dimensioned by the maximum number of CBBs which may be scheduled by the DCI. However, the actual number of CBBs transmitted by the gNB or UE may be smaller than the above maximum number.
One RV bit for each CBB. The number of RV bits may be equal to the number of NDI bits.
In one embodiment of the disclosure, if a joint DCI is used to schedule both downlink and uplink transmission, the DCI may indicate one or more of the following:
A start HPN which may apply to the first CBB scheduled by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for subsequent CBBs scheduled by the DCI.
One NDI bit for each CBB of the scheduled PDSCH and PUSCH. The total number of NDI bits of the scheduled PDSCH and PUSCH by the DCI may be configured by high layer signaling. The exact number of NDI bits for the scheduled PDSCH and PUSCH may be further determined by a high layer signaling or indicated by the DCI. The actual number of CBBs transmitted by the gNB or NE may be smaller than the above maximum number.
One RV bit for each CBB. The number of RV bits may be equal to the number of NDI bits. In one embodiment of the disclosure, to schedule a downlink or uplink transmission, a DCI may indicate one or more of the following:
A start HPN which may apply to the first CBB scheduled by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for the multiple subsequent CBBs scheduled by the DCI.
One NDI bit for each CBB. The number of NDI bits may need to be dimensioned by the maximum number of CBBs which can be scheduled by the DCI. However, the actual number of CBB transmitted by the gNB or NE may be smaller than the above maximum number.
One RV for all scheduled new transmissions and/or one RV for all scheduled retransmissions. Whether a CBB is a new transmission or retransmission may be derived by the NDI bit of the CBB. Then, the RV for the CBB can be determined.
In one embodiment of the disclosure, if a joint DCI is used to schedule both downlink and uplink transmission, the DCI may indicate
A start HPN which may apply to the first CBB scheduled by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for the multiple subsequent CBBs scheduled by the DCI.
One NDI bit for each CBB of the scheduled PDSCH and PUSCH. The total number of NDI bits of the scheduled PDSCH and PUSCH by the DCI may be configured by high layer signaling. The exact number of NDI bits for the scheduled PDSCH and PUSCH may be further determined by a high layer signaling or indicated by the DCI. The actual number of CBBs transmitted by the gNB or NE may be smaller than the above maximum number.
One RV for all scheduled new transmissions and/or one RV for all scheduled retransmissions. Whether a CBB is a new transmission or retransmission may be derived by the NDI bit of the CBB. Then, the RV for the CBB can be determined.
In one embodiment of the disclosure, the CBBs that are scheduled by a DCI may be divided into two sets, e.g. setA and setB. To schedule a downlink or uplink transmission, the DCI may indicate one or more of the following:
A start HPN which may apply to the first CBB scheduled by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for the multiple subsequent CBBs scheduled by the DCI.
One NDI bit may be indicated in the DCI to determine a new transmission or a retransmission for the HARQ process with start HPN. The same determination of new transmission or retransmission may apply to all CBBs in setA. The CBBs in setB may be indicated explicitly by the DCI. For example, the offset B from the indicated start HPN and the number of HPNs for setB may be be indicated. Alternatively, only offset B from the indicated start HPN may be indicated for setB, and setB may last until the maximum number of CCBs that are scheduled by the DCI have been transmitted. Alternatively, multiple sets of consecutive CCBs may be indicated for setB. In all cases, the setB may last until the maximum number of CCBs that are scheduled by the DCI are transmitted. A CBB in setB may have a different new transmission or retransmission from setA.
One RV for setA and/or one RV for setB. Each of the RV fields may use 2 bits or 1 bit.
Figure 3 illustrates the differentiation of setA 310 and setB 315. Specifically, Figure 3 depicts the start HPN 305, CBB setA 310, CBB setB 315, the maximum configured number of CBBs 320, the number of CBBs 325 in CBB set B 315, and the offset B 330. SetB 315 may have a size of 0 CBB, so that all scheduled CBB belong to setA 310 and follow the new transmission or retransmission of the HARQ process with start HPN 305.
In this scheme, if NDI is not indicated in the DCI, a fixed determination of new transmission or retransmission could apply to setA 310 and setB 315.
In this scheme, instead of a single NDI bit, two NDI bits can be indicated in the DCI to determine a new transmission or a retransmission for the HARQ process with start HPN. The same determination of new transmission or retransmission may apply to all CBBs in setA. The two NDI bits include one toggling bit and one absolute bit. From the gNB point of view, the toggling bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with the start HPN by checking whether the bit is toggled or not toggled. Meanwhile, the absolute bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with start HPN by checking the value of the bit directly. The toggling bit and the absolute bit may indicate the same information.
From the UE point of view, the absolute bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with start HPN by checking the value of the bit directly. Meanwhile, the toggling bit indicates whether the current DCI schedules a new TB or retransmission of the latest TB for the HARQ process with start HPN by checking whether the bit is toggled or not toggled. When the absolute bit indicates retransmission and the toggling bit indicates anew TB, the UE may be able to identify that at least one PDCCH is missed, and so the UE may schedule a retransmission of a new TB.
Figure 4 illustrates an example to check whether it is new transmission or retransmission for the start HPN using 2 NDI bits. For the sake of the discussion of Figure 4, it is assumed that the gNB sends a PDCCH 1 405 with HPN x which schedules a PDSCH. The toggling bit and absolute bit for NDI in PDCCH 1 405 are ‘0’ and ‘0’ respectively. Then, the UE may correctly receive (based on PDCCH 1 405) the PDSCH and transmits an ACK. The gNB may receive the ACK successfully and decide to schedule anew TB by transmitting PDCCH 2 410 using the same HPN x. To indicate a new transmission, the toggling bit and absolute bit for NDI in PDCCH 2 410 are ‘1’ and ‘1’ respectively. However, the UE may miss the PDCCH 2 410. The gNB may then transmit a PDCCH 3 415, which may schedule a retransmission of the new TB. The toggling bit and absolute bit for NDI in PDCCH 3 415 are ‘1’ and ‘0’ respectively. From the gNB point of view, comparing with PDCCH 2, the toggling bit in PDCCH 3 is not toggled, so it indicates retransmission, while the absolute bit indicates value ‘0’ which may also mean retransmission. From the UE point of view, after detection of PDCCH 3 415, the UE may know it is a retransmission by the absolute bit with value ‘O’. Meanwhile, the UE may know it is the retransmission of a new TB since the toggling bit is toggled in both PDCCH 3 415 and PDCCH 2 410.
In one embodiment of the disclosure, the CBBs for uplink data transmission that are scheduled by a DCI may be divided into three sets, e.g. setA, setB and setC. To schedule a downlink or uplink transmission, a DCI may indicate one or more of the following:
A start HPN, which may apply to the first CBB indicated by the DCI. The consecutive HPNs starting from the indicated start HPN may be serially used for the multiple subsequent CBBs indicated by the DCI.
One NDI bit may be indicated in the DCI to determine a new transmission or a retransmission for the HARQ process with the start HPN. The same determination of new transmission or retransmission may apply to all CBBs in setA.
The offset A of the first CBB in setA. The CBBs before the first CCB of setA may belong to setC. For a HPN in setC, it may be indicated that the CBB of the HPN is already successfully received at gNB, and there is no new CBB scheduled for the HPN. The CBBs in setB may be indicated explicitly by the DCI. A CBB in setB may have a different new transmission or retransmission from setA. For example, the offset B from the indicated start HPN and the number of HPNs for setB may be indicated by the DCI. Alternatively, only offset B from the indicated start HPN may be indicated for setB. Alternatively, multiple sets of consecutive CCBs may be indicated for setB. In all cases, the setB may last until the maximum number of CCBs that can be scheduled by the DCI. The total number of CBBs in setA, setB and setC may not exceed the maximum number of CBBs that are schedulable by a DCI. Alternatively, there may be no restriction on number of CBBs in setC, therefore, the total number of CBBs in setB and setC may not exceed the maximum number of CBBs that are schedulable by a DCI. One RV for setA and/or one RV for setB. Each RV field may use 2 bits or 1 bit.
Figure 5 illustrates the differentiation of setA 510, setB 515, and setC 535. Specifically, Figure 5 depicts the start HPN 505, CBB setA 510, CBB setB 515, the maximum configured number of CBBs 520, the number of CBBs 525 in CBB setB 515, the offset B 530, the CBB setC 535, and the offset A 540.
The offset A 540 may be 0, so that there is no CBB in setC 535. For a CBB in setC 535 of a UL transmission, the UE may flush the buffer of the CBB at the UE side. setB 515 may have a size of 0 CBB, so that all scheduled CBBs may belong to setA 510 and follow the new transmission or retransmission of the HARQ process with start HPN.
In this scheme, if NDI is not indicated in the DCI, a fixed determination of new transmission or retransmission could apply to setA 510 and/or setB 515.
In this scheme, instead of a single NDI bit, two NDI bits may be indicated in the DCI to determine a new transmission or a retransmission for the HARQ process with the start HPN 505. The same determination of new transmission or retransmission applies to all CBBs in setA 510. The two NDI bits includes one toggling bit and one absolute bit. From the gNB point of view, the toggling bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with start HPN by checking whether the bit is toggled or not toggled. Meanwhile, the absolute bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with start HPN 505 by checking the value of the bit directly. The toggling bit and the absolute bit may indicate the same information.
From the UE point of view, the absolute bit may indicate whether the current DCI schedules a new transmission or a retransmission for the HARQ process with start HPN 505 by checking the value of the bit directly. Meanwhile, the toggling bit may indicate whether the current DCI schedules a new TB or retransmission of the latest TB for the HARQ process with start HPN 505 by checking whether the bit is toggled or not toggled.
HARQ-ACK codebook based on HARQ processes
NR supports use of a Type3 HARQ-ACK codebook, which may be used to report HARQ- ACK bits for all configured HARQ processes. If the number of HPNs is large, e.g., on the order of approximately 100, the overhead for HARQ-ACK feedback in UL may also become very large too.
In one embodiment of the disclosure, to help to reduce the payload size of HARQ-ACK feedback, the start HPN and the number of consecutive HPNs may be indicated by a DCI. In this manner, the UE may only report HARQ-ACK for the indicated number of consecutive HPNs. Joint PCI to schedule PDSCH and/or PUSCH
A DCI may dynamically indicate the scheduling of PDSCH only, PUSCH only, or both PDSCH and PUSCH. In this case where both PDSCH and PUSCH are indicated, a two-bit field in the DCI is sufficient to differentiate the scheduling of PDSCH/PUSCH. It may be assumed for the sake of discussion of embodiments herein that HARQ-ACK is transmitted on PUSCH without the introduction of PUCCH.
If both PDSCH and PUSCH are scheduled by a DCI, the DCI may further indicate whether HARQ-ACK for a set of PDSCH(s) can be piggybacked on the PUSCH, e.g., by a 1 -bit indicator. In one embodiment, the set of PDSCH(s) may include the PDSCH scheduled by the DCI. In another embodiment, the set of PDSCH(s) may be required to include the PDSCH scheduled by the DCI.
If PDSCH is scheduled by a DCI without a scheduled UL data transmission, the fields in the DCI that are typically used for the UL data scheduling may be reused to indicate a PUSCH resource for the HARQ-ACK feedback. For example, certain value(s) of the timedomainresourceallocation (TDRA) field for PUSCH may be used to indicate the PUSCH resource. The value(s) may indicate a PUSCH resource that may not be used to carry uplink data transmission. Alternatively, the value(s) may indicate a PUSCH resource that may be used carry uplink data transmission irrespective of the piggyback of uplink control information.
If PUSCH is scheduled by a DCI without a scheduled DL data transmission, the DCI may further indicate whether HARQ-ACK for a set of PDSCH(s) may be piggybacked on the PUSCH, e.g., using a 1 -bit indicator.
Compression of NDI and HARQ-ACK
In one embodiment NDI indication in DCI and HARQ-ACK reporting in UL control information (UCI) for CBBs may be compressed to reduce signaling overhead. The compression may be achieved by signaling of the index of the bit sequence corresponding to the desired NDI and HARQ-ACK instead of the actual sequences of the bits. The overhead reduction may be achieved by defining an index for bit sequences more frequently used in the system. More specifically, the typical block error rate (BLER) is 0.1 for PDSCH and PUSCH transmission meaning that only 10% of CBBs are transmitted with errors.
For a sequence of length N corresponding to N CBBs, the compressed signaling may be defined as follows:
• 1 -bit indicating type of pattern - K ones or K zeros in the sequence of length N
• ceil(log2(Kmax) bits - actual number K (K<Kmax) of ones / zeros (depending of pattern type) in the sequence of length N • ceil(log2(nchoosek(N,K))) bits - index indicating position of K ones / zeros in the sequence of length N using combinatorial index (binomial coefficient enumeration) based on nchoosek() function
The format of compressed signaling is illustrated in Figure 6. Specifically, Figure 6 depicts a portion 605 that indicates pattern type (e.g., corresponding to the 1 -bit indicating type of pattern), a portion 610 that indicates the number of ones/zeros in the sequence (e.g., the ceil(log2(Kmax) bits), and a portion 615 that indicates the position of the ones and zeros in the sequence (e.g., the ceil(log2(nchoosek(N,K))) bits).
In another embodiment the sequence of bits used for NDI indication or HARQ-ACK reporting may be segmented into multiple sub-sequences of a pre-determined length. Each subsequence may be compressed independently from each other. An example of this is depicted in Figure 7 showing the overall sequence of bits 700, and then multiple sub-sequences 705 that are identifies as Group 1, Group 2, ... , Group P-1, and Group P.
In the other embodiment HARQ-ACK and NDI compression may be achieved by using start and length indicator value (SLIV) indication in the sequence of length N assuming a consecutive HARQ-ACK/NACK bits. The signaling of the offset and window may be defined by the nchoosek() function as described below. The signaling may optionally indicate the individual HARQ-ACK bits or NDI within the indicated window using combinatorial index (binomial coefficient enumeration) based on nchoosek() function such that K can be kept small.
The nchoosek function may be defined as n(n-l)(n-2)...(n-k+l) / k!. The combinatorial index may be defined as follows:
Figure imgf000012_0001
where 1 < so < si < ... < SK-I < N are the K sorted indices of bit for indication in the sequence of length N, and x > y
Figure imgf000012_0002
x < y
In another embodiment of the disclosure, the sequence of HARQ-ACK or NDI bits may be processed differentially to further reduce the number of bits for indications using a combinatorial index. More specifically, the original sequence b(i) may be updated to sequence c(i) as follows c(i) = b(i) ® b(i — 1) , where ® is XOR operation, i = 1...N and b(0) = 0. Then the compression function may be applied to the sequence c(i) . The example of this embodiment is illustrated in Figure 8. Specifically, Figure 8 depicts an example b it sequence b(i) 805 and c(i) 810. In some embodiments, the electronic device(s), network(s), system(s), chip(s) or component(s), or portions or implementations thereof, of Figures 11-13, below, or some other figure herein, may be configured to perform one or more processes, techniques, or methods as described herein, or portions thereof. One such process is depicted in Figure 9. In some embodiments, the process of Figure 9 may be performed by a UE or a portion thereof. For example, the process may include, at 901, identifying a received DCI to schedule transmission of multiple CBBs, wherein the DCI indicates aNDI for respective ones of the multiple CBBs.
At 902, the process may further include facilitating transmission or reception for one or more of the CBBs based on the DCI. For example, the CBBs may include downlink CBBs (e.g., received by the UE on a PDSCH) and/or uplink CBBs (e.g., transmitted by the UE on a PUSCH).
Figure 10 illustrates another process in accordance with various embodiments. In some embodiments, the process of Figure 10 may be performed by a base station (e.g., a gNB) or a portion thereof. For example, the process may include, at 1001, facilitating transmission of a DCI to a UE, the DCI to schedule transmission of multiple CBBs, wherein the DCI indicates a NDI for respective ones of the CBBs.
At 1002, the process may further include facilitating transmission or reception of the multiple CBBs based on the DCI. For example, the CBBs may include downlink CBBs (e.g., transmitted by the gNB on a PDSCH) and/or uplink CBBs (e.g., received by the gNB on a PUSCH).
For one or more embodiments, at least one of the components set forth in one or more of the preceding figures may be configured to perform one or more operations, techniques, processes, and/or methods as set forth in the example section below. For example, the baseband circuitry as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below. For another example, circuitry associated with a UE, base station, network element, etc. as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below in the example section.
Figures 11-13 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.
Figure 11 illustrates a network 1100 in accordance with various embodiments. The network 1100 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems, or the like. The network 1100 may include a UE 1102, which may include any mobile or non-mobile computing device designed to communicate with a RAN 1104 via an over-the-air connection. The UE 1102 may be communicatively coupled with the RAN 1104 by a Uu interface. The UE 1102 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic/engine control unit, electron! c/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
In some embodiments, the network 1100 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
In some embodiments, the UE 1102 may additionally communicate with an AP 1106 via an over-the-air connection. The AP 1106 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 1104. The connection between the UE 1102 and the AP 1106 may be consistent with any IEEE 802.11 protocol, wherein the AP 1106 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 1102, RAN 1104, and AP 1106 may utilize cellular- WLAN aggregation (for example, LWA/LWIP). Cellular- WLAN aggregation may involve the UE 1102 being configured by the RAN 1104 to utilize both cellular radio resources and WLAN resources.
The RAN 1104 may include one or more access nodes, for example, AN 1108. AN 1108 may terminate air interface protocols for the UE 1102 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 1108 may enable data/voice connectivity between CN 1120 and the UE 1102. In some embodiments, the AN 1108 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 1108 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 1108 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.
In embodiments in which the RAN 1104 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 1104 is an LTE RAN) or an Xn interface (if the RAN 1104 is a 5G RAN). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.
The ANs of the RAN 1104 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 1102 with an air interface for network access. The UE 1102 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 1104. For example, the UE 1102 and RAN 1104 may use carrier aggregation to allow the UE 1102 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc.
The RAN 1104 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.
In V2X scenarios the UE 1102 or AN 1108 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like.

In some embodiments, the RAN 1104 may be an LTE RAN 1110 with eNBs, for example, eNB 1112. The LTE RAN 1110 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI-RS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.
In some embodiments, the RAN 1104 may be an NG-RAN 1114 with gNBs, for example, gNB 1116, or ng-eNBs, for example, ng-eNB 1118. The gNB 1116 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 1116 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 1118 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 1116 and the ng-eNB 1118 may connect with each other over an Xn interface.
In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 1114 and a UPF 1148 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN1114 and an AMF 1144 (e.g., N2 interface).
The NG-RAN 1114 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G-NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.
In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 1102 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 1102, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 1102 with different amount of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 1102 and in some cases at the gNB 1116. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
The RAN 1104 is communicatively coupled to CN 1120 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 1102). The components of the CN 1120 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 1120 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 1120 may be referred to as a network slice, and a logical instantiation of a portion of the CN 1120 may be referred to as a network sub-slice.

The UPF 1148 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 1136, and a branching point to support multi-homed PDU session. The UPF 1148 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF- to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 1148 may include an uplink classifier to support routing traffic flows to a data network.
The NSSF 1150 may select a set of network slice instances serving the UE 1102. The NSSF 1150 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 1150 may also determine the AMF set to be used to serve the UE 1102, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 1154. The selection of a set of network slice instances for the UE 1102 may be triggered by the AMF 1144 with which the UE 1102 is registered by interacting with the NSSF 1150, which may lead to a change of AMF.

NEF 1152 may also translate information exchanged with the AF 1160 and information exchanged with internal network functions. For example, the NEF 1152 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 1152 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 1152 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 1152 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 1152 may exhibit an Nnef servicebased interface.
The NRF 1154 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances.

The UDR may store subscription data and policy data for the UDM 1158 and the PCF 1156, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 1102) for the NEF 1152. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 1158, PCF 1156, and NEF 1152 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM- FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 1158 may exhibit the Nudm service-based interface.
The AF 1160 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control.
In some embodiments, the 5GC 1140 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 1102 is attached to the network. This may reduce latency and load on the network. To provide edge computing implementations, the 5GC 1140 may select a UPF 1148 close to the UE 1102 and execute traffic steering from the UPF 1148 to data network 1136 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 1160. In this way, the AF 1160 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 1160 is considered to be a trusted entity, the network operator may permit AF 1160 to interact directly with relevant NFs. Additionally, the AF 1160 may exhibit an Naf service-based interface. The data network 1136 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application/content server 1138.
