SYSTEMS AND METHODS FOR RESOURCE MAPPING ENHANCEMENTTECHNICAL FIELD
[0001] The disclosure relates generally to wireless communications, including but not limited to systems and methods for resource mapping / repetition enhancement.BACKGROUND
[0002] The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called 5G New Radio (5G NR) as well as a Next Generation Packet Core Network (NG-CN or NGC) . The 5G NR will have three main components: a 5G Access Network (5G-AN) , a 5G Core Network (5GC) , and a User Equipment (UE) . In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based, and some being hardware based, so that they could be adapted according to need. Communication via satellite is one of the typical scenarios of the non-terrestrial networks in 3GPP standardization.SUMMARY
[0003] The example embodiments disclosed herein are directed to solving the issues relating to one or more of the problems presented in the prior art, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompany drawings. In accordance with various embodiments, example systems, methods, devices and computer program products are disclosed herein. It is understood, however, that these embodiments are presented by way of example and are not limiting, and it will be apparent to those of ordinary skill in the art who read the present disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of this disclosure.
[0004] At least one aspect is directed to a system, method, apparatus, or a computer-readable medium of the following. A wireless communication device (e.g., a user equipment (UE) ) may determine one or more configuration parameters for a physical uplink shared channel (PUSCH) transmission. The wireless communication device may perform a pattern of resource mapping to the PUSCH transmission based on the determined one or more configuration parameters. In some embodiments, the one or more configuration parameters may indicate at least one of: the pattern of resource mapping, wherein the pattern of the resource mapping is at least one repeated transmission of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots (e.g., nSlots, a repetition) ; an application scheme of orthogonal cover code (OCC) to the PUSCH transmission, wherein the application scheme of OCC is across at least one of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots ; an index of an OCC sequence; a length of the OCC sequence; a repetition number (e.g., ) ; a number of repetitions of identical slots (e.g., ) ; a number of scheduled resource units (RUs) ; a number of consecutive subcarriers; a number of repetitions of identical symbols; or a number of identical repetitions of consecutive slots (e.g., nSlots) .
[0005] In some embodiments, the pattern of resource mapping can be indicated via at least of: a high layer signaling; or a downlink control information (DCI) signaling; or associating the pattern of resource mapping of the PUSCH transmission with the application scheme of OCC.

In some embodiments, the 2-length OCC sequence can be [W0 W1] , the element of the sequence can be multiplied onto 2 repetition of consecutive slots (e.g., consecutive slots is 2, [W0 multiplied by 2slot1 W1 multiplied by 2slot1] ) .

[0031] 1. Mobile Communication Technology and Environment
[0032] FIG. 1 illustrates an example wireless communication network, and / or system, 100 in which techniques disclosed herein may be implemented, in accordance with an embodiment of the present disclosure. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of things (NB-IoT) network, and is herein referred to as “network 100. ” Such an example network 100 includes a base station 102 (hereinafter “BS 102” ; also referred to as wireless communication node) and a user equipment device 104 (hereinafter “UE 104” ; also referred to as wireless communication device) that can communicate with each other via a communication link 110 (e.g., a wireless communication channel) , and a cluster of cells 126, 130, 132, 134, 136, 138 and 140 overlaying a geographical area 101. In Figure 1, the BS 102 and UE 104 are contained within a respective geographic boundary of cell 126. Each of the other cells 130, 132, 134, 136, 138 and 140 may include at least one base station operating at its allocated bandwidth to provide adequate radio coverage to its intended users.
[0033] For example, the BS 102 may operate at an allocated channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118, and an uplink radio frame 124 respectively. Each radio frame 118 / 124 may be further divided into sub-frames 120 / 127 which may include data symbols 122 / 128. In the present disclosure, the BS 102 and UE 104 are described herein as non-limiting examples of “communication nodes, ” generally, which can practice the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communications, in accordance with various embodiments of the present solution.
[0034] FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of Figure 1, as described above.
[0035] System 200 generally includes a base station 202 (hereinafter “BS 202” ) and a user equipment device 204 (hereinafter “UE 204” ) . The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with one another as necessary via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with one another as necessary via a data communication bus 240. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for transmission of data as described herein.
[0036] As would be understood by persons of ordinary skill in the art, system 200 may further include any number of modules other than the modules shown in Figure 2. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend upon the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure
[0037] In accordance with some embodiments, the UE transceiver 230 may be referred to herein as an "uplink" transceiver 230 that includes a radio frequency (RF) transmitter and a RF receiver each comprising circuitry that is coupled to the antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in time duplex fashion. Similarly, in accordance with some embodiments, the BS transceiver 210 may be referred to herein as a "downlink" transceiver 210 that includes a RF transmitter and a RF receiver each comprising circuity that is coupled to the antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in time duplex fashion. The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0038] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212 / 232 that can support a particular wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as the Long Term Evolution (LTE) and emerging 5G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternate, or additional, wireless data communication protocols, including future standards or variations thereof.
[0039] In accordance with various embodiments, the BS 202 may be an evolved node B (eNB) , a serving eNB, a target eNB, a femto station, or a pico station, for example. In some embodiments, the UE 204 may be embodied in various types of user devices such as a mobile phone, a smart phone, a personal digital assistant (PDA) , tablet, laptop computer, wearable computing device, etc. The processor modules 214 and 236 may be implemented, or realized, with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0040] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in firmware, in a software module executed by processor modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may be coupled to the processor modules 210 and 230, respectively, such that the processors modules 210 and 230 can read information from, and write information to, memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by the processor modules 210 and 230, respectively.
[0041] The network communication module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bi-directional communication between base station transceiver 210 and other network components and communication nodes configured to communication with the base station 202. For example, network communication module 218 may be configured to support internet or WiMAX traffic. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface such that base station transceiver 210 can communicate with a conventional Ethernet based computer network. In this manner, the network communication module 218 may include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC) ) . The terms “configured for, ” “configured to” and conjugations thereof, as used herein with respect to a specified operation or function, refer to a device, component, circuit, structure, machine, signal, etc., that is physically constructed, programmed, formatted and / or arranged to perform the specified operation or function.
[0042] The Open Systems Interconnection (OSI) Model (referred to herein as, “open system interconnection model” ) is a conceptual and logical layout that defines network communication used by systems (e.g., wireless communication device, wireless communication node) open to interconnection and communication with other systems. The model is broken into seven subcomponents, or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI Model also defines a logical network and effectively describes computer packet transfer by using different layer protocols. The OSI Model may also be referred to as the seven-layer OSI Model or the seven-layer model. In some embodiments, a first layer may be a physical layer. In some embodiments, a second layer may be a Medium Access Control (MAC) layer. In some embodiments, a third layer may be a Radio Link Control (RLC) layer. In some embodiments, a fourth layer may be a Packet Data Convergence Protocol (PDCP) layer. In some embodiments, a fifth layer may be a Radio Resource Control (RRC) layer. In some embodiments, a sixth layer may be a Non Access Stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer being the other layer.
[0043] Various example embodiments of the present solution are described below with reference to the accompanying figures to enable a person of ordinary skill in the art to make and use the present solution. As would be apparent to those of ordinary skill in the art, after reading the present disclosure, various changes or modifications to the examples described herein can be made without departing from the scope of the present solution. Thus, the present solution is not limited to the example embodiments and applications described and illustrated herein. Additionally, the specific order or hierarchy of steps in the methods disclosed herein are merely example approaches. Based upon design preferences, the specific order or hierarchy of steps of the disclosed methods or processes can be re-arranged while remaining within the scope of the present solution. Thus, those of ordinary skill in the art will understand that the methods and techniques disclosed herein present various steps or acts in a sample order, and the present solution is not limited to the specific order or hierarchy presented unless expressly stated otherwise.
[0044] 2. Systems and Methods for Resource Mapping Enhancement
[0045] To address the conflict between limited resources and larger number of user equipments (UEs) , one approach is to improve the uplink capacity. Moreover, non-terrestrial networks (NTN) can be supported. A satellite communication system can cover a wider variety and quantity of UEs due to its wide coverage. For example, a narrowband internet of things (NB-IoT) NTN can be deployed. In some deployments, it is clearly emerging that a system, such as for NB-IoT, may have to support massive capacity in terms of number and types of UEs, some of which have worse characteristics than others (e.g., low cost devices, or wearables) . However, capacity analysis indicates that the current UL system capacity is limited.
[0046] The methods to expand physical uplink shared channel (PUSCH) capacity in terrestrial networks / non-terrestrial networks (TN / NTN) can be implemented, for example, using symbol / slot / repetition / redundancy version (RV) -level OCC. However, since orthogonal cover code (OCC) can be applied to the same data resource, the mapping mechanism of narrow band physical uplink shared channel (NPUSCH) codewords may need to be enhanced to adapt to the OCC mechanism. In the present disclosure, methods to enhance the mapping of NPUSCH transmission (s) are discussed.
[0047] FIG. 3 illustrates an example implementation of non-terrestrial networks (NTN) communication, in accordance with some embodiments of the present disclosure. The structure of transparent NTN is illustrated in FIG. 3. A link between a UE and a satellite can be a service link. A link between a BS and a satellite can be a feeder link and may be common for all UEs within the same cell.
[0048] Resource units can be used to describe the mapping of the NPUSCH transmission (s) to resource elements. A resource unit can be defined as SC-FDMA symbols in the time domain and consecutive subcarriers in the frequency domain, where and are given by Tables 1 and 2 for frame structure types 1 and 2, respectively.
[0049] Table 1: Supported combinations of and for frame structure type 1.
[0050] Table 2: Supported combinations of and for frame structure type 2.
[0051] Each NPUSCH codeword (e.g., a pattern of resource mapping to each NPUSCH transmission) can be mapped to one or more than one resource units, NRU. Each of which can be be transmitted times, which can be configured by a higher layer signaling (e.g., Msg3 repetition number field in UL grant of random access response (RAR) ) or repetition number field in corresponding DCI (format N0) , and may represent the number of NPUSCH repetitions.
[0052] The block of complex-valued symbols can be multiplied with the amplitude scaling factor βNPUSCH in order to conform to the transmit power PNPUSCH, and mapped in sequence starting with z (0) to subcarriers assigned for transmission of NPUSCH. The mapping to resource elements (k, l) corresponding to the subcarriers assigned for transmission and not used for transmission of reference signals can be in increasing order of first the index k, then the index l, starting with the first slot in the assigned resource unit.
[0053] Meanwhile, in order to improve uplink soft coverage and ensure data transmission quality, after mapping to Nslots slots, the Nslots slots can be repeated additional times, before continuing the following slot mapping, where
[0054] In some embodiments, the can be determined by at least one of: the number being 1 when the number of resource units is 1; or the number being a minimum value between a first factor and 4 when the number of resource units is larger than 1, wherein the first factor can be the repetition number divided by 2 and rounded up.
[0055] From the formula, for the 15 kHz subcarrier spacing, after mapping the code word on a pair of slots, the pair of slots can be repeated additional times before the mapping of the code word continues. In case of 3.75 kHz transmission, the mapping can be done on a single slot before repeating, after mapping the code word on a slot, the slot can be repeated 0 additional times before mapping of the code word continues, that is to say, after each NPUSCH codeword is mapped to one or more than one resource units, each of which can be transmitted times.
[0056] In some examples, when the repetition number is 8, the number of scheduled UL resource units can be 2, allocated subcarriers are multi-tone (e.g., 3, 6, 12) . FIG. 4 illustrates a resource mapping of NPUSCH codeword for multi-tone. FIG. 4 shows the transmission of a transport block (TB) . The first pair of slots 1, 2 can be repeated additional times before the mapping continues to the second pair of slots 3, 4. After 16 slots the full code word has been repeated four times and the scrambling is reinitialized, the redundancy version can be updated. The procedure can be then repeated once to complete eight repetitions of the TB in total.
[0057] In some examples, when the repetition number is 2, the number of scheduled UL resource units can be 1, allocated subcarriers are single-tone (e.g., 1 subcarrier / frequency / band) . FIG. 5 illustrates a resource mapping of NPUSCH codeword for single-tone. FIG. 5 shows the transmission of a TB. After 16 slots the full code word has been repeated 1 times and the scrambling is reinitialized, the redundancy version can be updated. The procedure can be then repeated once to complete two repetitions of the TB in total.
[0058] Moreover, the following implementation examples, the enhanced resource mapping can be used in PUSCH / NPUSCH transmission (s) in NTN / TN. The RV cycle can be [0 2 0 2... ] . Each element of the cycle may correspond to repetition of the TB. That is to say, consecutive repetitions may have same RV. In following implementation examples, the RV, repetition, and / or repetitions can be applied.
[0059] Implementation Example 1: Slot-level resource mapping of PUSCH codeword enhancement
[0060] A wireless communication device (e.g., a user equipment (UE) ) may determine one or more configuration parameters for a physical uplink shared channel (PUSCH) transmission. The wireless communication device may perform a pattern of resource mapping to the PUSCH transmission based on the determined one or more configuration parameters. In some embodiments, the one or more configuration parameters may indicate at least one of: the pattern of resource mapping, wherein the pattern of the resource mapping is at least one repeated transmission of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots (e.g., nSlots, a repetition) ; an application scheme of orthogonal cover code (OCC) to the PUSCH transmission, wherein the application scheme of OCC is across at least one of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots ; an index of an OCC sequence; a length of the OCC sequence; a repetition number (e.g., ) ; a number of repetitions of identical slots (e.g., ) ; a number of scheduled resource units (RUs) ; a number of consecutive subcarriers; a number of repetitions of identical symbols; or a number of identical repetitions of consecutive slots (e.g., nSlots) .
[0061] In some embodiments, the pattern of resource mapping can be indicated via at least of: a high layer signaling; or a downlink control information (DCI) signaling; or associating the pattern of resource mapping of the PUSCH transmission with the application scheme of OCC. The association can be that: the pattern of resource mapping is the repeated transmission of the one or more slots when the application scheme of OCC is across one or more slots; or the pattern of resource mapping is the repeated transmission of the one or more symbols when the application scheme of OCC is across one or more symbols. In some embodiments, a type of the PUSCH, for example, may include: a new radio (NR) PUSCH, internet of things (IoT) PUSCH, long term evolution (LTE) PUSCH, enhanced machine-type communication (eMTC) PUSCH, or other UL channel carrying data or information in NR / LTE / eMTC / IoT / ultra-reliable low latency communications (URLLC) .
[0062] The mapping to resource elements (k, l) corresponding to the subcarriers assigned for transmission and not used for transmission of reference signals can be in increasing order of first the index k, then the index l, starting with the first slot in the assigned resource unit.
[0063] In the present disclosure, the figures are provided as examples to illustrate the cases but do not represent the only implementation methods. A configuration corresponds implementation example 1 can be: repetition number is 8, multi-tone (e.g., 12) , scheduled RUs NRU is 2, subcarrier spacing is 15kHz.
[0064] Case-1: In some embodiments, if the pattern of resource mapping is / represents / indicates the repeated transmission of the one or more slots, the mapping can be performed a first number of times until the repetition number is reached when a condition is satisfied. The condition may comprise: the number of repetitions of identical slots is greater than and / or equal to the length of the OCC sequence (e.g., >= occLength, >occLength, or = occLength) . In some embodiments, the condition can be that the number of repetitions of identical slots is greater than the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical slots is equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical slots is greater than and equal to the length of the OCC sequence. For each subsequent time (e.g., each first number of times) the mapping is performed, a different redundancy version (RV) can be used. For example, existing configuration can be reused. The unit can be slot (s) . The slot can be repeated until slots are repeated, then following slot until full code word has been repeated repetition. If / when >=occLength or > occLength, or = occLength, after mapping to the first slots (e.g., 1 slot, or 2 slots) , the slots can be repeated additional times, where
[0065] After the first slot has been repeated times, the redundancy version can be updated, then the first slot may continue to be repeated additional times. After the first slot has been repeated times, the mapping procedure for the following slot can be then performed to complete all slots mapping / repetition of the TB, as shown in FIG. 6. FIG. 6 illustrates a slot-level resource mapping of PUSCH codeword with 8 repetitions and 2 resource units (RUs) . In this bullet, the legacy redundancy version cycle may be not changed, e.g., [0 2 0 2 0 2 ... ] . In some embodiments, for 16 repetitions: the pattern of resource mapping can be: 1111 (rv0) 1111 (rv2) 1111 (rv0) 1111 (rv2) 2222, etc. In some embodiments, for 4 repetitions, the mapping can be: 11 (rv0) 11 (rv2) 22 (rv0) . Each element represents a slot.
[0066] In some embodiments, if the pattern of resource mapping is / represents / indicates the repeated transmission of the one or more slots, the mapping is performed a first number of times with a same redundancy version (RV) until a second number of times is reached when a condition is satisfied. The condition may comprise: the number of repetitions of identical slots is smaller than the length of the OCC sequence (e.g., <occLength) . For example, if <occLength, after the first slot has been repeated times, the redundancy version may not be updated, then the first slot may continue to be repeated additional times.
[0067] In some embodiments, if the pattern of resource mapping is / represents / indicates the repeated transmission of the one or more slots, the mapping can be performed a third number of times until the repetition number is reached when a condition is satisfied. The condition may comprise: the second number of times is smaller than the repetition number (e.g., ) . For each subsequent time (e.g., the third number of times) the mapping is performed, a different RV is used. For example, if the RV may be updated and repeated the procedure. After the first slot has been repeated times, the mapping procedure for the following slot can be then performed to complete all slots mapping / repetition of the TB, as shown in FIG. 7. FIG. 7 illustrates a slot-level resource mapping of PUSCH codeword with 8 repetitions and 2 RUs. In this bullet, the redundancy version cycle can be changed, e.g., [0 0 2 2 0 0 ... ] . The same mechanism can be used both for single-tone and multi-tone.
[0068] Case-2: If the pattern of resource mapping is / represents / indicates the repeated transmission of the one or more slots, the mapping can be performed a first number of times until the repetition number is reached when a condition is satisfied. The condition may comprise: the number of repetitions of identical slots is greater than and / or equal to the length of the OCC sequence (e.g., >= occLength, > occLength, or = occLength) . In some embodiments, the condition can be that the number of repetitions of identical slots is greater than the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical slots is equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical slots is greater than and equal to the length of the OCC sequence. For each subsequent time (e.g., each first number of times) the mapping is performed, a different redundancy version RV can be used. For example, existing configuration can be reused. The unit can be slot (s) . The slot can be repeated until slots are repeated, then following slot until full code word has been repeated repetition, then repeated the procedure until repetition. If >= occLength or > occLength, or = occLength, after mapping to the first slots (e.g., 1 slot, or 2 slots) , the slots can be be repeated additional times, before continuing the following slot mapping, where
[0069] After the full code word has been repeated times, the redundancy version can be updated. The procedure can be then repeated once to complete repetitions of the TB in total, as shown in FIG. 8. FIG. 8 illustrates a slot-level resource mapping of PUSCH codeword with 8 repetition and 2 RUs. In this bullet, the redundancy version cycle may not be changed, e.g., [0 2 0 2 0 2 ... ] .
[0070] If the pattern of resource mapping is / represents / indicates the repeated transmission of the one or more slots, the mapping can be performed a first number of times with a same redundancy version (RV) until a second number of times is reached when a condition is satisfied. The condition may comprise: the number of repetitions of identical slots is smaller than the length of the OCC sequence (e.g., <occLength) . In some embodiments, after reaching the second number of times, the mapping can be performed a third number of times until the PUSCH repetition number is reached. For each subsequent time (e.g., each third number of times) that the mapping is performed, a different RV can be used. For example, if <occLength, after the full code word has been repeated times, the redundancy version may not be updated, the procedure can be then repeated. Then the redundancy version can be updated and the procedure can be repeated to complete repetitions of the TB in total, as shown in FIG. 9. FIG. 9 illustrates a slot-level resource mapping of PUSCH codeword with 8 repetition and 2 RUs. In this bullet, the redundancy version cycle may be changed, e.g., [0 0 2 2 0 0 ... ] . The same mechanism can be used both for single-tone and multi-tone.
[0071] Case-3: In some embodiments, if the pattern of the resource mapping is / represents / indicates the repeated transmission of the one or more slots, a mapping can be performed a number of times with a same redundancy version (RV) until the first number of repetitions of identical slots is reached when a condition is satisfied. The condition may comprise: the number of repetitions of identical slots is equal to the length of the OCC sequence. In some embodiments, when the length of OCC sequence is configured via high layer signaling or DCI signaling, the number of repetition of identical slots is determined as: equal to the length of OCC sequence. For each subsequent times (e.g., each first number of times) that the mapping is performed, a different RV can be used. In some embodiments, a mapping performed means slot / symbol level mapping corresponding to the pattern of resource mapping. For example, the number of repetitions of identical slots for PUSCH (e.g., 4) can be defined, which may equal to the length of the OCC or the number of multiplexed UEs (e.g., when the length of OCC sequence is configured, is determined) . The slot may be repeated until slots are repeated, then following slot until full code word has been repeated repetition. The procedure may be repeated until repetition. The mapping defined in case-2 of implementation example-1 can be copied.
[0072] After mapping to the first slots (e.g., 1 slot, or 2 slots, or nSlots) , the slots can be repeated additional times, before continuing the following slot mapping. After the full code word has been repeated times, the redundancy version can be updated. The procedure can be then repeated once to complete repetitions of the TB in total, as shown in FIG. 8. In this case, the legacy redundancy version cycle may be unchanged, e.g., [0 2 0 2 0 2 ... ] . The same mechanism can be used both for single-tone and multi-tone (e.g., multiple carriers / frequencies / bands) .
[0073] Implementation Example 2: Symbol-level resource mapping of PUSCH codeword enhancement
[0074] A wireless communication device (e.g., a user equipment (UE) ) may determine one or more configuration parameters for a physical uplink shared channel (PUSCH) transmission. The wireless communication device may perform a pattern of resource mapping to the PUSCH transmission based on the determined one or more configuration parameters. In some embodiments, the one or more configuration parameters may indicate at least one of: the pattern of resource mapping, wherein the pattern of the resource mapping is at least one repeated transmission of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots (e.g., nSlots, a repetition) ; an application scheme of orthogonal cover code (OCC) to the PUSCH transmission, wherein the application scheme of OCC is across at least one of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots ; an index of an OCC sequence; a length of the OCC sequence; a repetition number (e.g., ) ; a number of repetitions of identical slots (e.g., ) ; a number of scheduled resource units (RUs) ; a number of consecutive subcarriers; a number of repetitions of identical symbols; or a number of identical repetitions of consecutive slots (e.g., nSlots) .
[0075] In some embodiments, the pattern of resource mapping can be indicated via at least of: a high layer signaling; or a downlink control information (DCI) signaling; or associating the pattern of resource mapping of the PUSCH transmission with the application scheme of OCC. The association can be that: the pattern of resource mapping is the repeated transmission of the one or more slots when the application scheme of OCC is across one or more slots; or the pattern of resource mapping is / represents the repeated transmission of the one or more symbols when the application scheme of OCC is across one or more symbols. In some embodiments, a type of the PUSCH, for example, may include: a new radio (NR) PUSCH, internet of things (IoT) PUSCH, long term evolution (LTE) PUSCH, enhanced machine-type communication (eMTC) PUSCH, or other UL channel carrying data or information in NR / LTE / eMTC / IoT / ultra-reliable low latency communications (URLLC) .
[0076] The mechanism in implementation example-1 defines the slot-level resource mapping; for the symbol-level resource mapping, a similar mechanism can be reused. In this implementation example, the unit can be symbol. The mapping to resource elements (k, l) corresponding to the subcarriers assigned for transmission and not used for transmission of reference signals can be in increasing order of first the index k, then the index l, starting with the first slot in the assigned resource unit.
[0077] Case-1: In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the one or more symbols, a mapping can be performed a first number of times until the repetition number is reached when a condition is satisfied. The condition may comprise: the number of identical symbols is greater than and / or equal to the length of the OCC sequence (e.g., >= occLength, > occLength, or = occLength) . In some embodiments, the condition can be that the number of repetitions of identical symbols is greater than the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical symbols is equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of repetitions of identical symbols is greater than and equal to the length of the OCC sequence.

[0078] After the first symbol has been repeated times, the redundancy version can be updated, then the first symbol may continue to be repeated times. After the first symbol has been repeated times, the mapping procedure for the following slot can be then performed to complete all repetitions of the TB. In this bullet, the legacy redundancy version cycle can be unchanged, e.g., [0 2 0 2 0 2 ... ] .
[0079] In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the one or more symbols, the mapping can be performed a first number of times with a same RV until a second number of times is reached when a condition is satisfied. The condition may comprise: the number of repetition of identical symbols is smaller than the length of the OCC sequence (e.g., <occLength) . For example, if <occLength, after the first symbol has been repeated times, the redundancy version may not be updated, then the first symbol may continue to be repeated additional times.
[0080] In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the one or more symbols, the mapping can be performed a third number of times until the repetition number is reached when a condition is satisfied. The condition may comprise: the second number of times is smaller than the repetition number (e.g., ) . For each subsequent time (e.g., each second number of times) that the mapping is performed, a different RV can be used. For example, if the RV may be updated, and the procedure can be repeated. After the first symbol has been repeated times, the mapping procedure of the following symbol can be then performed to complete all symbols mapping / repetition of the TB. In this bullet, the redundancy version cycle can be changed, e.g., [0 0 2 2 0 0 ... ] . The same mechanism can be used both for single-tone and multi-tone.
[0081] Case-2: In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the one or more symbols, a mapping can be performed a first number of times until the repetition number is reached when a condition is satisfied.

[0086] Implementation Example 3: Repetition (e.g., consecutive slots) -level resource mapping of PUSCH codeword enhancement
[0087] A wireless communication device (e.g., a user equipment (UE) ) may determine one or more configuration parameters for a physical uplink shared channel (PUSCH) transmission. The wireless communication device may perform a pattern of resource mapping to the PUSCH transmission based on the determined one or more configuration parameters. In some embodiments, the one or more configuration parameters may indicate at least one of: the pattern of resource mapping, wherein the pattern of the resource mapping is at least one repeated transmission of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots (e.g., nSlots) ; an application scheme of orthogonal cover code (OCC) to the PUSCH transmission, wherein the application scheme of OCC is across at least one of: one or more slots, or one or more symbols, or one or more consecutive subcarriers, or consecutive slots ; an index of an OCC sequence; a length of the OCC sequence; a repetition number (e.g., ) ; a number of repetitions of identical slots (e.g., ) ; a number of scheduled resource units (RUs) ; a number of consecutive subcarriers; a number of repetitions of identical symbols; or a number of identical repetitions of consecutive slots (e.g., nSlots) .
[0088] In some embodiments, the pattern of resource mapping can be indicated via at least of: a high layer signaling; or a downlink control information (DCI) signaling; or associating the pattern of resource mapping of the PUSCH transmission with the application scheme of OCC. The association can be that: the pattern of resource mapping is the repeated transmission of the one or more slots when the application scheme of OCC is across one or more slots; or the pattern of resource mapping is the repeated transmission of the one or more symbols when the application scheme of OCC is across one or more symbols. In some embodiments, a type of the PUSCH, for example, may include: a new radio (NR) PUSCH, internet of things (IoT) PUSCH, long term evolution (LTE) PUSCH, enhanced machine-type communication (eMTC) PUSCH, or other UL channel carrying data or information in NR / LTE / eMTC / IoT / ultra-reliable low latency communications (URLLC) .
[0089] The repetition for single-tone and multi-tone may include / occupy at least 2 slots. The redundancy versions between two adjacent OCCs may be different, so OCCs cannot be used directly. The mechanisms in implementation examples-1 and 2 define the slot-level and symbol-level resource mapping; for the repetition (e.g., consecutive slots) -level resource mapping, a similar mechanism can be reused. The mapping to resource elements (k, l) corresponding to the subcarriers assigned for transmission and not used for transmission of reference signals can be in increasing order of first the index k, then the index l, starting with the first slot in the assigned resource unit.
[0090] Case-1: In some embodiments, if the pattern of the resource mapping is the repeated transmission of the one or more consecutive slots, a mapping can be performed a first number of times in a number of sets of slots until the repetition number is reached when a condition is satisfied. The condition may comprise: the number of identical repetitions of consecutive slots is greater than and / or equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is greater than the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is greater than and equal to the length of the OCC sequence. For each subsequent time (e.g., each first number of times) that the mapping is performed, a different redundancy version (RV) can be used. For example, existing configuration can be reused. The unit can be repetition-unit (e.g., 2slots or more) . The Nslotsslots can be repeated until repetition are repeated, then following Nslotsslots until full code word has been repeated repetition. The procedure can be repeated until repetition. If >= occLength or > occLength or =occLength, after mapping to the Nslotsslots, the slots can be repeated additional times, before continuing the following slot mapping, where Nslots=2, Δf=3.75kHz or 15kHz
[0091] After the full code word has been repeated times, the redundancy version can be updated. The procedure can be then repeated once to complete repetitions of the TB in total, as shown in FIG. 10. FIG. 10 illustrates a repetition-level resource mapping of PUSCH codeword with multi-tone, 16 repetitions, and 1 RU. In this bullet, the RV cycle is unchanged.
[0092] In some embodiments, if the pattern of the resource mapping is the repeated transmission of the consecutive slots, a mapping can be performed a first number of times in a number of sets of slots with a same redundancy version (RV) until reaching the second number of times when a condition is satisfied. The condition may comprise: the number of identical repetition of consecutive slots is smaller than the length of the OCC sequence. In some embodiments, after reaching the second number of times, the mapping can be performed a third number of times in a number of sets of slots until the repetition number is reached. For each subsequent time (e.g., each third number of times) that the mapping is performed, a different RV can be used. If <occLength, after the full code word has been repeated times, the redundancy version may not be updated, the procedure can be then repeated. Then the redundancy version can be updated, and the procedure can be repeated to complete repetitions of the TB in total, as shown in FIG. 11. FIG. 11 illustrates a repetition-level resource mapping of PUSCH codeword with multi-tone, 16 repetitions, and 1 RU. In this bullet, the redundancy version cycle can be changed, e.g., [0 0 2 2 0 0 ... ] . The same mechanism can be used both for single-tone and multi-tone.
[0093] Case-2: In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the consecutive slots, a mapping can be performed a first number of times in a number of sets of slots until the repetition number is reached when a condition is satisfied. The condition may comprise: the number of identical repetitions of consecutive slots is greater than and / or equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is greater than the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is equal to the length of the OCC sequence. In some embodiments, the condition can be that the number of identical repetitions is greater than and equal to the length of the OCC sequence. For each subsequent time (e.g., each first number of times) that the mapping is performed, a different redundancy version (RV) can be used. For example, existing configuration can be reused. The unit can be repetition-unit (e.g., 2slots or more) . The Nslotsslots can be repeated until repetition are repeated, then following Nslotsslots until full code word has been repeated repetition. The procedure can be repeated until repetition. If >= occLength or > occLength or = occLength, after mapping to the Nslotsslots, the slots shall be repeated additional times, before continuing the following slot mapping, where
[0094] After the full code word has been repeated times, the redundancy version can be updated. The procedure can be then repeated once to complete repetitions of the TB in total. The RV cycle can be unchanged.
[0095] In some embodiments, if the pattern of the resource mapping is / represents the repeated transmission of the consecutive slots, the mapping can be performed a first number of times in a number of sets of slots with a same redundancy version (RV) until reaching the length of the OCC sequence when a condition is satisfied. The condition may comprise: the number of identical repetitions of consecutive slots is smaller than the length of the OCC sequence. After reaching the length of the OCC sequence, the mapping can be performed a second number of times in a number of sets of slots until the repetition number is reached. For each subsequent time (e.g., each second number of times) the mapping is performed, a different RV can be used. For example, if (e.g., 1) <occLength (e.g., 4) , after the full code word has been repeated times, the redundancy version may not be updated, the procedure can be then repeated and / or until the identical repetition satisfy the number of OCC length or multiplexed-UEs. Then the redundancy version can be updated, and the procedure can be repeated to complete repetitions of the TB in total, for single-tone, as shown in FIG. 12. FIG. 12 illustrates a repetition-level resource mapping of PUSCH codeword with single-tone, 8 repetition, and 1 RU. In this bullet, the redundancy version cycle may be changed, e.g., [0 0 0 0 2 2 2 2 ... ] for single-tone. The same mechanism can be used both for single-tone and multi-tone.
[0096] Case-3: In some embodiments , if the pattern of the resource mapping is / represents the repeated transmission of the consecutive slots, a mapping can be performed a first number of times with a same redundancy version in a number of sets of slots until reaching the length of the OCC sequence when a condition is satisfied. The condition may comprise: the number of identical repetitions of consecutive slots is equal to the length of the OCC sequence. In some embodiments, when the length of OCC sequence is configured via high layer signaling or DCI signaling, the number of repetition of consecutive slots is determined as: equal to the length of OCC sequence. In some embodiments , after reaching the length of the OCC sequence, the mapping can be performed a second number of times in a number of sets of slots until the repetition number is reached. For each subsequent time (e.g., each second number of times) that the mapping is performed, a different redundancy version (RV) can be used. In some embodiments, a mapping performed means consecutive slot level mapping corresponding to the pattern of resource mapping. In some embodiments, a repetition of a transmission block includes one or more repetitions of one or more different consecutive slots. For example, the number of identical repetitions for PUSCH can be defined, which may equal to the length of the OCC or the number of multiplexed UEs (e.g., when the length of OCC sequence is configured, is determined) . The Nslotsslots may be repeated until repetition are repeated, then following Nslotsslots until full code word has been repeated repetition. The procedure can be repeated until repetition is reached / done. The mapping defined in case-1 of implementation example-3 can be copied.
[0097] After mapping to the Nslots slots, the slots shall be repeated additional times, before continuing the following slot mapping, where
[0098] Nslots=2, Δf=3.75kHz or 15kHz.
[0099] After the full code word has been repeated times, the redundancy version can be updated. The procedure can be then repeated once to complete repetitions of the TB in total. The same mechanism can be used both for single-tone and multi-tone.
[0100] In above implementation examples, the OCC can be applied across slots / symbol / repetition as defined in implementation example-1, implementation example-2 and implementation example-3. In above implementation examples, multiple resource mapping schemes can be defined; the specific scheme can be configured by network via a high layer signaling or DCI signaling, for example, parameter-1 corresponds to case-1 in implementation example-1, parameter-2 corresponds to case-2 in implementation example-2.
[0101] In some embodiments, the specific mapping scheme can be associated with the OCC parameters, for example, OCC scheme-1 corresponds to case-2 in implementation example-1, OCC scheme-2 corresponds to case2 in implementation example-2, OCC scheme-3 corresponds to case-1 in implementation example-3. When the OCC scheme is not configured, a legacy resource mapping can be used in background. For example, OCC sequence length-1 corresponds to case-2 in implementation example-1, OCC sequence length-2 corresponds to case-2 in implementation example-2. When the OCC sequence length is not configured, a resource mapping can be used in background. In other words, which resource mapping case is used can be determined by one or more parameters related to the OCC mechanism.
[0102] It should be understood that one or more features from the above / following implementation examples are not exclusive to the specific implementation examples, but can be combined in any manner (e.g., in any priority and / or order, concurrently or otherwise) .

reaching the length of the OCC sequence when a condition is satisfied, wherein the condition comprises:the number of identical repetitions of consecutive slots is smaller than the length of the OCC sequence; andafter reaching the length of the OCC sequence, the mapping is performed a second number of times in a number of sets of slots until the repetition number is reached,wherein for each subsequent time the mapping is performed, a different RV is used.18.The method of claim 2 or 3, wherein if the pattern of the resource mapping is the repeated transmission of the consecutive slots, the mapping is performed a first number of times with a same redundancy version in a number of sets of slots until reaching the length of the OCC sequence when a condition is satisfied, wherein the condition comprises:the number of identical repetitions of consecutive slots is equal to the length of the OCC sequence.19.The method of claim 18, wherein after reaching the length of the OCC sequence, the mapping is performed a second number of times in a number of sets of slots until the repetition number is reached,wherein for each subsequent time that the mapping is performed, a different redundancy version (RV) is used.20.A method comprising:sending, by a wireless communication node to a wireless communication device, one or more configuration parameters for a physical uplink shared channel (PUSCH) transmission,wherein the wireless communication device performs a pattern of resource mapping to the PUSCH transmission based on the one or more configuration parameters.21.A non-transitory computer readable medium storing instructions, which when executed by at least one processor, cause the at least one processor to perform the method of any one of claims 1-20.22.An apparatus comprising:at least one processor configured to perform the method of any one of claims 1-20.
