[0029] In wireless communication systems, network communication devices, such as base stations (e.g., eNB, gNB), can support transmitting downlink communications to one or more user communication devices (e.g., UEs). Additionally or alternatively, the network communication devices can support receiving uplink communications from one or more user communication devices. With increasing demands for higher throughput and efficient resource utilization in wireless communication systems, it may be desirable to support, for example, multiplexing uplink communications (e.g., mobile-initiated (MO) data transmissions) associated with multiple user communication devices (e.g., multiple UEs) on a single subcarrier (e.g., 3.75 kHz). By implementing multiplexing uplink communications associated with multiple user communication devices on a single subcarrier, wireless communication systems can improve uplink throughput (e.g., capacity).

[0030] Various aspects of this disclosure relate to enabling wireless communication systems (including one or more network communication devices or user communication devices) to support multiplexing uplink communications associated with multiple UEs on the same resource (e.g., one or more time resources or frequency resources) for uplink transmission using multiplexing sequences (e.g., orthogonal cover code (OCC) sequences). In some embodiments, the network communication device (e.g., a base station) may transmit an uplink configuration to the UE (e.g., via Radio Resource Control (RRC) signaling, etc.). Based on the uplink configuration, the UE may apply multiplexing sequences to process uplink data, wherein the multiplexing sequences are associated with a spreading factor. The UE will also transmit the processed uplink data to the network communication device in physical resources based on the uplink configuration. The multiplexing sequences will distinguish UEs multiplexed at the same time-frequency resource, which will result in an improvement in uplink throughput (e.g., capacity).

[0031] Aspects of this disclosure are described in the context of wireless communication systems.

[0032] Figure 1 This section describes an example of a wireless communication system 100 according to aspects of this disclosure. The wireless communication system 100 may include one or more NEs 102, one or more UEs 104, and a core network (CN) 106. The wireless communication system 100 may support various radio access technologies. In some embodiments, the wireless communication system 100 may be a 4G network, such as an LTE network or an LTE-A network. In some other embodiments, the wireless communication system 100 may be an NR network, such as a 5G network, a 5G-A network, or a 5G Ultra Wideband (5G-UWB) network. In other embodiments, the wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable radio access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. The wireless communication system 100 may support radio access technologies other than 5G, such as 6G. In addition, the wireless communication system 100 can support technologies such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), or Code Division Multiple Access (CDMA).

[0033] One or more NEs 102 may be distributed across a geographical area to form a wireless communication system 100. One or more of the NEs 102 described herein may be, include, or be referred to as a network node, base station, network element, network function, network entity, radio access network (RAN), NodeB, eNodeB (eNB), next-generation NodeB (gNB), or other suitable terms. NEs 102 and UEs 104 may communicate via a communication link, which may be a wireless or wired connection. For example, NEs 102 and UEs 104 may perform wireless communication (e.g., receive signaling, transmit signaling) via a Uu interface.

[0034] NE 102 can provide a geographic coverage area that supports services for one or more UEs 104 within that geographic coverage area. For example, NE 102 and UE 104 can support wireless communication of signals associated with services (e.g., voice, video, packet data, messaging, broadcasting, etc.) based on one or more radio access technologies. In some embodiments, NE 102 can be mobile, for example, a satellite associated with a non-terrestrial network (NTN). In some embodiments, different geographic coverage areas 112 associated with the same or different radio access technologies can overlap, but different geographic coverage areas can be associated with different NEs 102.

[0035] One or more UEs 104 may be distributed across a geographical area of ​​the wireless communication system 100. UE 104 may include or be referred to as a remote unit, mobile device, wireless device, remote device, subscriber device, transmitter device, receiver device, or some other suitable term. In some implementations, UE 104 may be referred to as a unit, station, terminal, or client, and other instances thereof. Additionally or alternatively, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, and other instances thereof.

[0036] UE 104 may be able to support direct wireless communication with other UE 104 via a communication link. For example, UE 104 may support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, communication link 114 may be referred to as a side link. For example, UE 104 may support direct wireless communication with another UE 104 via a PC5 interface.

[0037] NE 102 may support communication with CN 106 or with another NE 102 or both. For example, NE 102 may interface with other NE 102 or CN 106 via one or more backhaul links (e.g., S1, N2, N2, or network interfaces). In some embodiments, NE 102 may communicate directly with each other. In some other embodiments, NE 102 may communicate with each other or indirectly (e.g., via CN 106). In some embodiments, one or more NE 102 may include sub-components, such as access network entities, which may be instances of access node controllers (ANCs). The ANC may communicate with one or more UE 104s via one or more other access network transmitting entities (which may be referred to as radio heads, smart radio heads, or transmit-receive points (TRPs)).

[0038] CN 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. CN 106 can be an evolved packet core (EPC) or a 5G core (5GC), which may include control plane entities (e.g., Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) that manage access and mobility, and user plane entities (e.g., Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) that route packets or interconnect to external networks. In some implementations, the control plane entities may manage non-access stratum (NAS) functions of one or more UEs 104 served by one or more NEs 102 associated with CN 106, such as mobility, authentication, and bearer management (e.g., data bearers, signaling bearers, etc.).

[0039] CN 106 can communicate with the packet data network via one or more backhaul links (e.g., via S1, N2, N2, or another network interface). The packet data network may contain an application server. In some implementations, one or more UEs 104 can communicate with the application server. UE 104 can establish a session (e.g., a Protocol Data Unit (PDU) session, etc.) with CN 106 via NE 102. CN 106 can use the established session (e.g., an established PDU session) to route services (e.g., control information, data, etc.) between UE 104 and the application server. A PDU session may be an instance of a logical connection between UE 104 and CN 106 (e.g., one or more network functions of CN 106).

[0040] In the wireless communication system 100, NE 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some embodiments, NE 102 and UE 104 may support different resource structures. For example, NE 102 and UE 104 may support different frame structures. In some embodiments, such as in 4G, NE 102 and UE 104 may support a single frame structure. In some other embodiments, such as in 5G and other suitable radio access technologies, NE 102 and UE 104 may support various frame structures (i.e., multiple frame structures). NE 102 and UE 104 may support various frame structures based on one or more parameter sets.

[0041] The wireless communication system 100 may support one or more parameter sets, and the parameter sets may include subcarrier spacing and cyclic prefixes. A first parameter set (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a regular cyclic prefix. In some embodiments, the first parameter set (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one time slot per subframe. A second parameter set (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a regular cyclic prefix. A third parameter set (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a regular cyclic prefix or an extended cyclic prefix. A fourth parameter set (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a regular cyclic prefix. A fifth parameter set (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a regular cyclic prefix.

[0042] Time intervals for resources (e.g., communication resources) can be organized according to frames (also known as radio frames). Each frame may have a duration, for example, 10 milliseconds (ms). In some embodiments, each frame may contain multiple subframes. For example, each frame may contain 10 subframes, and each subframe may have a duration, for example, 1 ms. In some embodiments, each frame may have the same duration. In some embodiments, each subframe of a frame may have the same duration.

[0043] Alternatively, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may contain a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more parameter sets supported in the wireless communication system 100. For example, the first, second, third, fourth, and fifth parameter sets (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with corresponding subcarrier intervals of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe, respectively. Each time slot may contain a certain number (e.g., quantity) of symbols (e.g., OFDM symbols). In some embodiments, the number (e.g., quantity) of time slots in a subframe may depend on the parameter set. For a conventional cyclic prefix, a time slot may contain 14 symbols. For an extended cyclic prefix (e.g., applicable to a 60 kHz subcarrier spacing), a time slot may contain 12 symbols. The relationship between the number of symbols per time slot for the regular cyclic prefix and the extended cyclic prefix, the number of time slots per subframe, and the number of time slots per frame may depend on the parameter set. It should be understood that references to the first parameter set (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and time slots.

[0044] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 may support one or more operating frequency bands, such as frequency range names FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4 (52.6 GHz to 114.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), and FR5 (114.25 GHz to 300 GHz). In some embodiments, NE 102 and UE 104 may perform wireless communication on one or more of the operating frequency bands. In some embodiments, FR1 may be used by NE 102 and UE 104, as well as other equipment or devices, for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by NE 102 and UE 104, as well as other equipment or devices, for short-range, high data rate capabilities.

[0045] FR1 may be associated with one or more parameter sets (e.g., at least three parameter sets). For example, FR1 may be associated with a first parameter set containing a 15 kHz subcarrier spacing (e.g., μ=0); a second parameter set containing a 30 kHz subcarrier spacing (e.g., μ=1); and a third parameter set containing a 60 kHz subcarrier spacing (e.g., μ=2). FR2 may be associated with one or more parameter sets (e.g., at least two parameter sets). For example, FR2 may be associated with a third parameter set containing a 60 kHz subcarrier spacing (e.g., μ=2); and a fourth parameter set containing a 120 kHz subcarrier spacing (e.g., μ=3).

[0046] To multiplex UEs on the same physical resource used for uplink transmission, such as the same time-frequency resource in a scheduled uplink resource or a pre-configured uplink resource (PUR), a multiplexing sequence will be used to process uplink data (cyclically if necessary) to distinguish UEs, for example, starting from a reference timeslot (or an absolute timeslot, such as timeslot #0 or the starting timeslot of a scheduled uplink transmission). Regarding the PUR, it can be a dedicated PUR, where the uplink time-frequency resource can be exclusively used by one UE at a time, or it can be a shared PUR, where the same uplink time-frequency resource can be used simultaneously by one or more UEs (e.g., at most two UEs).

[0047] Exemplary uplink data for applying multiplexed sequences can be PUSCH transmissions (or simply PUSCH, etc.). Taking IoT NTN, particularly for narrowband (NB) IoT (NBIoT), as an example, uplink data can be NBIoT PUSCH (NPUSCH), for example, NPUSCH format 1 (which is used for uplink data rather than for feedback information). Exemplary NPUSCH format 1 resource consumption. One uplink time slot. N rep The number of repetitions is indicated by the repetition count field in the downlink control information (DCI) format N0, or by the repetition count configured by a higher layer for a pre-configured uplink. RU The number of resource units is indicated by the resource allocation field of DCI format N0 or by higher-layer parameters for the pre-configured uplink. This refers to the number of time slots in the resource unit specified in TS36.211, for example, as described in Table 10.1.2.3-1 below. It is the number of allocated subcarriers used for NPUSCH transmission, and It is the number of symbols in each uplink slot (e.g., 7).

[0048] 36.211 - Table 10.1.2.3-1

[0049]

[0050] Furthermore, regarding NB-IoT Resource Units (RUs), compared to traditional LTE, it is a new concept in uplink resource allocation and was introduced by LTE-NB as the basic unit for PUSCH allocation. This unit can employ several different configuration types. Each NPUSCH codeword can be mapped to one or more resource units, each of which should be transmitted multiple times (or have repetitions).

[0051] In some embodiments of this disclosure, the multiplexing sequence is based on an OCC sequence, such as a Walsh sequence or other quasi-orthogonal sequence. The sequence index of the OCC sequence used for the multiplexing sequence may be configured by higher-layer parameters in the uplink configuration, or may be determined based on predefined rules or UE ID-related information (e.g., UE ID or Cell-to-Radio Network Temporary Identifier (C-RNTI)). For example, the sequence index of the multiplexing sequence may be generated or determined as the C-RNTI modulo the maximum multiplexing sequence number (or referred to as the maximum number of multiplexings in the device or the spreading factor associated with the multiplexing sequence).

[0052] Figure 2 This is an example of NPUSCH processed by an OCC sequence in the case of a single tone (or subcarrier) according to aspects of this disclosure.

[0053] refer to Figure 2 Assuming the uplink data is transmitted in NPUSCH format 1 for single-tone cases, where N... rep =4, N RU =2 and =16. For a single-tone NPUSCH (or a single-tone NPUSCH), the UE can transmit a complete TB, and then transmit another TB with a different RV, and the RV cycle will continue until the repetition count is reached. This means that the time span of the OCC sequence can be in units of one TB transmission (or two repetitions of each RV (e.g., RV0 and RV2)). Therefore, a TB is in units of 4 repetitions (N). rep =4) Emissions, for example, blocks #1, #2, #3, and #4. According to 36.211-Table 10.1.2.3-1, each TB contains 2 Ru (N RU =2), and each RU contains 16 time slots ( =16). Therefore, the total transmission duration for each repetition is 32 time slots. For NPUSCH format 1 transmission, RV cycling is supported in the [0,2] mode. Therefore, in Figure 2In this context, OCC operations (or OCC applications) in the time domain can span 64 time slots (e.g., an OCC operation between two identical data points in an uplink transmit time slot spans 64 time slots). That is, the time span for OCC operations is relatively long in the case of a single tone, and phase rotation caused by timing and frequency errors and drift can exist during the time span of the OCC sequence, which will degrade the performance of NPUSCH.

[0054] For multi-tone NPUCH (or multi-tone NPUSCH), OCC operations within the same data in repetitions or time slots can be applied to avoid long spans. However, a solution needs to be found for how to dynamically adjust the length of the OCC sequence when the number of NPUSCH repetitions changes.

[0055] Considering the case of a single note (or a single note pattern), =1) or polyphonic cases (or polyphonic patterns, The aforementioned problems related to the time span of the multiplexing sequence operation in >1) are addressed by resource mapping improvements in some aspects of this disclosure. The multiplexing sequence will be associated with a spreading factor, for example, M. occ (It can be associated with the length of the multiplexed sequence). The spreading factor is based on the uplink data frequency domain allocation, the configured repetition count, or a pre-configured spreading factor, for example, M. occ-1 One or more of them. For example, an OCC sequence can be a Walsh code of OCC length raised to the power of 2, or in the form of The Discrete Fourier Transform (DFT) code supports an OCC length of at least 7 (e.g., 1, 2, 3, 4, 5, 6, 7) and the associated spreading factor is a power of 2, or 1, 2, 3, 4, 5, 6, 7.

[0056] When using multiplexed sequences to process uplink data, the UE will divide each TB of uplink data (e.g., uplink data after channel coding and modulation, but before physical resource mapping), for example, each TB of samples, into several segments, for example, N. segment Each segment (e.g., N for the case of a single note) RU N ul,slot And 2N for cases with multiple notes RU N ul,slot Each segment (e.g., the number of uplink data mapped to a time slot unit) contains, for example, M. segment The number of uplink data segments is based on the uplink data frequency domain allocation (N). sc ), number of resource units (e.g., N) RU ) or the number of time slots per resource unit (e.g., One or more of the following. The UE then uses a multiplexed sequence to process each segment of the uplink data, where each processed segment is spread in the time domain using a spreading factor, which can be based on single-slot level, multi-slot level, single-sample level, multi-sample level, single-symbol level, or multi-symbol level, etc. That is, the multiplexed sequence can spread across the time domain at single-sample or multi-sample level, single-slot or multi-slot level, or single-symbol or multi-symbol level. For example, in the case of a single tone, the spreading factor, such as M... occ = min (N rep / 2, M occ-1 ), or for N rep =2,M occ =2, otherwise M occ =M occ-1 Furthermore, in cases with multiple tones, if N rep >4, then M occ = M occ-1 Otherwise M occ =2. Occasionally, spread spectrum may be based on the symbol level (e.g., OCC operation between two or more consecutive OFDM symbols), and N segment =( -1)N RU N ul,slot One symbol in each uplink time slot is used for the transmission of the demodulation reference signal (DMRS).

[0057] For example, uplink data processed by multiplexed sequences (e.g., OCC sequences with spreading factors) can be represented as follows:

[0058]

[0059] Among them, S( ) is processed uplink data, s( This is the uplink data before spread spectrum or processing, and its length is M. total n=0, 1, ..., N segment m = 0, 1, ..., M segment i = 0, 1, ..., M OCC And uplink data is used for spreading factors (e.g., M). OCC The associated multiplexed sequence w( Spreading is performed, which can be done per time slot, at several time slot levels, or even per symbol. Each segment of uplink data is multiplexed using a multiplexed sequence w( Spread spectrum can be performed. For example, in the case of a single tone, it can be an OCC spread spectrum based on a single time slot, N segment =N RU That is, in the case of a single tone, each segment processed by the multiplexed sequence will be mapped to a time slot. For the case of multiple tones, it can be OCC spread spectrum based on two time slots, N segment =2N RU That is, in the case of multiple tones, each segment processed by the multiplexed sequence will be mapped to two time slots.

[0060] Use multiplexed sequence w( The spread-spectrum uplink data will be transmitted in the time domain. For example, the spread-spectrum uplink data can be repeated a number of times (e.g., M). rep Repeated emission. Number of repetitions M rep The number of repetitions is configured (e.g., the number of repetitions N). rep And the spreading factor is determined, for example, M rep = N rep / M occ .

[0061] RV loops can also be applied to multiplexed sequences w( The uplink data is repeated for spread spectrum. For example, the UE will cyclically use two RVs across multiple time slot sub-blocks in a [0,2] pattern. The length of each sub-block (e.g., N) rv,subblock Based on uplink data frequency domain allocation, number of resource units, and number of time slots per resource unit. Or one or more of the spreading factors. For example, in the case of a single tone, the length of each sub-block (in terms of the number of time slots), N rv,subblock =M occ N RU Furthermore, in cases with multiple tones, if N rep >=4, then N rv,subblock = 4N RU Otherwise N rv,subblock =2N RU .

[0062] Figure 3 This is an example of NPUSCH emission in the case of a single tone, according to aspects of this disclosure.

It is also assumed that the spreading factor is Mocc=2, and the length of the multiplexed sequence (e.g., the OCC sequence) is also 2, e.g., w(0) and w(1). In the case of a single tone, each segment processed by the multiplexed sequence will be mapped to a time slot. The spread-spectrum uplink data will be processed in repetitions (e.g., M...). rep = N rep / M occ =2) Repeated transmission, and the length of each sub-block (e.g., block #1 and block #2 used for RV looping or switching in mode [0,2]) will be N, based on the number of uplink time slots. rv,subblock =M occ N RU =2 2 16=64 Each time slot.

[0067] refer to Figure 5 Assuming the uplink data is transmitted in NPUSCH format 1 with 12 tones, where N rep =16, N RU =2 and =2. It is also assumed that the spreading factor is Mocc=4, and the length of the multiplexed sequence (e.g., the OCC sequence) is also 4. Each segment processed by the multiplexed sequence will be mapped to 2 time slots. The spread-spectrum uplink data will be processed in terms of repetition count (e.g., M). rep = N rep / 4=4) is repeatedly emitted, and the length of each sub-block (e.g., blocks #1 to #4 used for RV looping or switching in mode [0,2]) will be N. rv,subblock =4N RU =4 2 2=16 Each time slot.

[0068] Figure 6 This is also an example of NPUSCH transmission in a multi-tone situation based on aspects of this disclosure.

[0069] refer to Figure 6 Assuming the uplink data is transmitted in NPUSCH format 1 with 12 tones, where N rep =16, N RU =2 and =2. It is also assumed that the spreading factor is Mocc=2, and the length of the multiplexed sequence (e.g., the OCC sequence) is also 2. Each segment processed by the multiplexed sequence will be mapped to 2 time slots. The spread-spectrum uplink data will be processed in terms of repetition count (e.g., M). rep = N rep / 4=4) is repeatedly emitted, and the length of each sub-block (e.g., blocks #1 to #4 used for RV looping or switching in mode [0,2]) will be N. rv,subblock =4N RU =4 2 2=16 Each time slot.

[0070] In some cases, uplink data can contain multiple terabytes (TB), for example, scheduled by a single DCI. For instance, for multiple interleaved TBs, NB-IoT UL slots... , (l=0, 1,…, g-1, c=0, 1,…, , r = 0, 1, ..., N TB -1) with TB r Related, where NBIoT UL slot n i This is the UL slot index i. In the case of a single tone, C=1, and in the case of multiple tones, C=4. TB r It is the r-th TB among the two scheduled TBs of NBIoT PUSCH format 1.

[0071] To support multiplexed sequences (e.g., OCC sequence-based multiplexing for single-tone and multi-tone uplink transmissions), the uplink time slots allocated for each TB will be updated based on the multiplexing sequence scheme. The UE will transmit multiple TBs in an interleaved manner, where each TB spans the duration of several time slots determined by the spreading factor. For example, in the multi-tone case, the maximum OCC length is no greater than 4, and each TB's sub-blocks will be... C=4 is used as a scheme without OCC multiplexing. For the single-tone case, each TB sub-block will be determined by the spreading factor, for example, M. occ N RU Among them, OCC multiplexing is introduced for NPUSCH format 1.

[0072] Figure 7 This is an example of multiple TB interleaved transmissions in a single-tone case according to aspects of this disclosure.

[0073] refer to Figure 7 Assuming two TBs are interleaved in the case of a single tone, for example, TB#1 and TB#2, where N rep =4, N RU =2 and =16.

[0074] In case (a), without the application of multiplexing sequences, each TB of sub-blocks will be CN. RU = 1 2 16 = 32 N uplink time slots, and for each sub-block with 4 repetitions per TB, N rep =4. Therefore, the four sub-blocks of TB#1 (e.g., four TB#1a) will be repeated in a loop, the four sub-blocks of TB#2 (e.g., four TB#2a) will be repeated in a loop, and each sub-block of TB#1 and TB#2 will be interleaved with each other.

[0075] In case (b), a multiplexing sequence, such as an OCC sequence, is applied for each TB. It is also assumed that the spreading factor is Mocc = 4, and the length of the multiplexing sequence (e.g., the OCC sequence) is also 4. The transmit duration of each TB sub-block will be determined by the spreading factor (e.g., M). occ N RU =4 2 16 = 128 (N time slots) and for each TB (e.g., TB1, TB2), the number of repetitions is N. rep / M OCC=1. Therefore, in case (b), TB#1 contains one sub-block, for example, TB#1b, and TB#2 contains one sub-block, for example, TB#2b.

[0076] Figure 8 This is another example of multiple TB interleaved transmission in a single-tone case according to aspects of this disclosure.

[0077] refer to Figure 8 It is also assumed that two TBs are interleaved in the case of a single tone, for example, TB#1 and TB#2, where N rep =4, N RU =2 and =16.

[0078] In case (a), without multiplexing sequences, the duration of each TB sub-block will be CN. RU = 1 2 16=32 N time slots, and for each sub-block of TB, N rep =4. Therefore, TB#1 will contain 4 sub-blocks, for example, 4 TB#1a, and TB#2 will contain 4 sub-blocks, for example, 4 TB#2b. In addition, the RV of mode [0,2] will be applied cyclically to each sub-block, that is, the RV will switch once every 32 slots.

[0079] In case (b), a multiplexing sequence, such as an OCC sequence, is applied for each TB. It is also assumed that in case (b), the spreading factor is Mocc = 2, and the length of the multiplexing sequence (e.g., the OCC sequence) is 2. The duration of each TB sub-block will be determined by the spreading factor, for example, M... occ N RU =2 2 16=64 One time slot. Therefore, in case (b), for each sub-block of every TB, the number of repetitions will be =2. Therefore, TB#1 contains 2 repeating sub-blocks, for example, 2 TB#1b, and TB#2 contains 2 repeating sub-blocks, for example, 2 TB#2b, where each sub-block has 64 time slots.
