[0015] As will be appreciated by those skilled in the art, aspects of the embodiments can be embodied as a system, a device, a method, or a program product. Accordingly, the embodiments can take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.), or an embodiment combining software and hardware aspects (commonly referred to herein as "circuitry", "module", or "system"). Additionally, the embodiments can take the form of a program product embodied in one or more computer-readable storage devices storing machine-readable code, computer-readable code, and / or program code (hereinafter referred to as code). The storage device can be tangible, non-transitory, and / or non-transmissive. The storage device may not embody a signal. In certain embodiments, the storage device only accesses the code by using a signal.

[0016] Some of the functional units described in this specification may be marked as modules to more specifically emphasize their implementation independence. For example, a module may be implemented as a hardware circuit, which includes a custom very large scale integration ("VLSI") circuit or gate array, off-the-shelf semiconductors (such as logic chips), transistors, or other discrete components. A module may also be implemented in a programmable hardware device (such as a field programmable gate array, programmable array logic, programmable logic device, etc.).

[0017] A module may also be implemented in code and / or software for execution by various types of processors. For example, the identified code module may contain one or more physical or logical blocks of executable code, which may be organized, for example, as objects, procedures, or functions. However, the executable files of the identified module do not need to be physically located together, but may contain different instructions stored in different locations, which, when logically joined together, contain the module and achieve the stated purpose of the module.

[0018] In fact, a code module may be a single instruction, or many instructions, and may even be distributed over several different code segments, across different programs, and across several storage devices. Similarly, the operational data may be identified and described within the module and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set or may be distributed over different locations (including on different computer-readable storage devices). In the case where a module or a part of a module is implemented in software, the software part is stored on one or more computer-readable storage devices.

[0019] Any combination of one or more computer-readable media may be utilized. The computer-readable media may be a computer-readable storage media. The computer-readable storage media may be a storage device for storing code. The storage device may be, for example (but not limited to), an electronic, magnetic, optical, electromagnetic, infrared, holographic, micro-mechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.

[0020] More specific examples (a non-exhaustive list) of storage devices will include the following: an electrical connection having one or more wires, a portable computer floppy disk, a hard disk, a random access memory ("RAM"), a read-only memory ("ROM"), an erasable programmable read-only memory ("EPROM") or flash memory, a portable compact disc read-only memory ("CD-ROM"), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer-readable storage media may be any tangible media that can contain or store a program for use by or in connection with an instruction execution system, apparatus, or device.

[0021] The code for performing the operations of the embodiments can be any number of lines and can be written in any combination of one or more programming languages, including object-oriented programming languages such as Python, Ruby, Java, Smalltalk, C++, etc. and conventional procedural programming languages such as the "C" programming language, and / or machine languages such as assembly language. The code can be executed entirely on the user's computer, partially on the user's computer, executed as a stand-alone software package, partially on the user's computer and partially on a remote computer, or entirely on a remote computer or server. In the latter scenario, the remote computer can be connected to the user's computer through any type of network connection, including a local area network ("LAN") or a wide area network ("WAN"), or can be connected to an external computer (e.g., via the Internet using an Internet service provider).

[0022] References throughout this specification to "one embodiment", "an embodiment", or similar language mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases "in one embodiment", "in an embodiment", and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but rather refer to "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising", "including", "having", and variations thereof mean "including (but not limited to)" unless expressly specified otherwise. A list of items listed does not mean that any or all of the items are mutually exclusive unless expressly specified otherwise. The terms "a", "an", and "the" also refer to "one or more" unless expressly specified otherwise.

[0023] Furthermore, the features, structures, or characteristics of the described embodiments can be combined in any suitable manner. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of the embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the embodiments.

[0024] Aspects of the embodiments will now be described with reference to the schematic flowcharts and / or schematic block diagrams of methods, apparatuses, systems, and program products according to the embodiments. It will be understood that each block of the schematic flowcharts and / or schematic block diagrams, and combinations of blocks in the schematic flowcharts and / or schematic block diagrams, can be implemented by code. The code can be provided to a processor of a general-purpose computer, a special-purpose computer, or other programmable data processing device to produce a machine, such that the instructions executed by the processor of the computer or other programmable data processing device create means for implementing the functions / actions specified in the schematic flowcharts and / or schematic block diagrams.

[0025] The code can also be stored in a storage device that can direct a computer, other programmable data processing device, or other device to function in a particular manner, such that the instructions stored in the storage device produce an article of manufacture including instructions for implementing the functions / actions specified in the schematic flowcharts and / or schematic block diagrams.

[0026] The code can also be loaded onto a computer, other programmable data processing device, or other device to cause a series of operational steps to be performed on the computer, other programmable device, or other device to produce a computer-implemented process, such that the code executed on the computer or other programmable device provides a process for implementing the functions / actions specified in the flowcharts and / or block diagrams.

[0027] The schematic flowcharts and / or schematic block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of apparatuses, systems, methods, and program products according to various embodiments. In this regard, each block in the schematic flowcharts and / or schematic block diagrams can represent a module, segment, or portion of code that contains one or more executable instructions for implementing the specified logical function.

[0028] It should also be noted that in some alternative implementations, the functions recited in the blocks may not occur in the order noted in the figures. For example, two blocks shown in succession may in fact be executed substantially concurrently, or depending on the functions involved, the blocks may sometimes be executed in the reverse order. Other steps and methods can be conceived that are equivalent in function, logic, or effect to one or more blocks or portions thereof of the illustrated figures.

[0029] Although various arrow types and line styles may be employed in the flowcharts and / or block diagrams, it should be understood that they do not limit the scope of the corresponding embodiments. In fact, some arrows or other connectors can be used to merely indicate the logical flow of the depicted embodiments. For example, an arrow can indicate an unspecified duration of waiting or monitoring between the recited steps of the depicted embodiments. It will also be noted that each block of the block diagrams and / or flowcharts, and combinations of blocks in the block diagrams and / or flowcharts, can be implemented by a system based on dedicated hardware that performs a particular function or action, or by a combination of dedicated hardware and code.

[0030] The description of the elements in each figure may refer to the elements of the ongoing figure. Similar numbers refer to similar elements in all figures, including alternative embodiments of the similar elements.

[0031] Figure 1 An embodiment of a wireless communication system 100 for transmitting configuration indicator status associations is depicted. In one embodiment, the wireless communication system 100 includes a remote unit 102 and a network unit 104. Although Figure 1 a specific number of remote units 102 and network units 104 are depicted, those skilled in the art will recognize that any number of remote units 102 and network units 104 may be included in the wireless communication system 100.

[0032] In one embodiment, the remote unit 102 may include a computing device such as a desktop computer, laptop computer, personal digital assistant (“PDA”), tablet computer, smart phone, smart TV (e.g., a TV connected to the Internet), set-top box, gaming console, security system (including security cameras), in-vehicle computer, network device (e.g., router, switch, modem), aircraft, drone, etc. In some embodiments, the remote unit 102 includes a wearable device such as a smart watch, fitness bracelet, optical head-mounted display, etc. Additionally, the remote unit 102 may be referred to as a subscriber unit, mobile device, mobile station, user, terminal, mobile terminal, fixed terminal, subscriber station, user equipment (“UE”), user terminal, device, or other terms used in the art. The remote unit 102 may communicate directly with one or more of the network units 104 via UL communication signals. In certain embodiments, the remote unit 102 may communicate directly with other remote units 102 via sidelink communication.

[0033] Network element 104 can be distributed within a geographical area. In some embodiments, network element 104 may also be referred to as and / or may include one or more of access point, access terminal, base, base station, Node B, evolved Node B (“eNB”), 5G Node B (“gNB”), home Node B, relay node, device, core network, air server, radio access node, access point (“AP”), New Radio (“NR”), network entity, access and mobility management function (“AMF”), unified data management (“UDM”), unified data repository (“UDR”), UDM / UDR, policy control function (“PCF”), radio access network (“RAN”), network slice selection function (“NSSF”), operation, administration, and management (“OAM”), session management function (“SMF”), user plane function (“UPF”), application function, authentication server function (“AUSF”), security anchor function (“SEAF”), trusted non-3GPP gateway function (“TNGF”), or any other terms used in the art. Network element 104 is generally part of a radio access network that includes one or more controllers communicatively coupled to one or more corresponding network elements 104. The radio access network is generally communicatively coupled to one or more core networks, which may be coupled to other networks such as the Internet and other networks such as the public switched telephone network. These and other elements of the radio access and core networks are not shown but are generally well known to those of ordinary skill in the art.

[0034] In one implementation, wireless communication system 100 complies with the NR protocol standardized in the Third Generation Partnership Project (“3GPP”), where network element 104 transmits on the downlink (“DL”) using an OFDM modulation scheme, and remote unit 102 transmits on the uplink (“UL”) using a single carrier frequency division multiple access (“SC-FDMA”) scheme or an orthogonal frequency division multiplexing (“OFDM”) scheme. However, more generally, wireless communication system 100 may implement some other open or proprietary communication protocols, such as, WiMAX, Institute of Electrical and Electronics Engineers (“IEEE”) 802.11 variants, Global System for Mobile Communications (“GSM”), General Packet Radio Service (“GPRS”), Universal Mobile Telecommunications System (“UMTS”), Long Term Evolution (“LTE”) variants, Code Division Multiple Access 2000 (“CDMA2000”), ZigBee, Sigfox, and other protocols. The present disclosure is not intended to be limited to implementations of any particular wireless communication system architecture or protocol.

[0035] The network unit 104 may serve multiple remote units 102 within a service area (e.g., a cell or a cell sector) via a wireless communication link. The network unit 104 transmits DL communication signals to serve the remote units 102 in the time, frequency, and / or spatial domains.

[0036] In various embodiments, the remote unit 102 may receive first information indicating a first set of transmission configuration indicator states from at least one network device (e.g., the network unit 104). In various embodiments, the remote unit 102 may receive second information indicating a second set of transmission configuration indicator states from at least one network device. In some embodiments, the remote unit 102 may determine an association between the first set of transmission configuration indicator states and a first set of transmission opportunities. In various embodiments, the remote unit 102 may determine an association between the second set of transmission configuration indicator states and a second set of transmission opportunities. Thus, the remote unit 102 may be used for transmission configuration indicator state association.

[0037] Figure 2 Depicts one embodiment of a device 200 that may be used for transmission configuration indicator state association. The device 200 includes one embodiment of the remote unit 102. Additionally, the remote unit 102 may include a processor 202, a memory 204, an input device 206, a display 208, a transmitter 210, and a receiver 212. In some embodiments, the input device 206 and the display 208 are combined into a single device, such as a touch screen. In certain embodiments, the remote unit 102 may not include any input device 206 and / or display 208. In various embodiments, the remote unit 102 may include one or more of the processor 202, the memory 204, the transmitter 210, and the receiver 212, and may not include the input device 206 and / or the display 208.

[0038] In one embodiment, the processor 202 may include any known controller capable of executing computer-readable instructions and / or capable of performing logical operations. For example, the processor 202 may be a microcontroller, a microprocessor, a central processing unit (“CPU”), a graphics processing unit (“GPU”), an auxiliary processing unit, a field-programmable gate array (“FPGA”), or a similar programmable controller. In some embodiments, the processor 202 executes instructions stored in the memory 204 to perform the methods and routines described herein. The processor 202 is communicatively coupled to the memory 204, the input device 206, the display 208, the transmitter 210, and the receiver 212.

[0039] In one embodiment, the memory 204 is a computer-readable storage medium. In some embodiments, the memory 204 includes volatile computer storage media. For example, the memory 204 may include RAM, which includes dynamic RAM ("DRAM"), synchronous dynamic RAM ("SDRAM"), and / or static RAM ("SRAM"). In some embodiments, the memory 204 includes non-volatile computer storage media. For example, the memory 204 may include a hard disk drive, flash memory, or any other suitable non-volatile computer storage device. In some embodiments, the memory 204 includes both volatile and non-volatile computer storage media. In some embodiments, the memory 204 also stores program code and associated data, such as an operating system or other controller algorithms operating on the remote unit 102.

[0040] In one embodiment, the input device 206 may include any known computer input device, including a touchpad, buttons, a keyboard, a stylus, a microphone, etc. In some embodiments, for example, the input device 206 may be integrated with the display 208 as a touchscreen or a similar touch-sensitive display. In some embodiments, the input device 206 includes a touchscreen such that text can be input using a virtual keyboard displayed on the touchscreen and / or by handwriting on the touchscreen. In some embodiments, the input device 206 includes two or more different devices, such as a keyboard and a touch panel.

[0041] In one embodiment, the display 208 may include any known electronically controllable display or display device. The display 208 may be designed to output visual, auditory, and / or tactile signals. In some embodiments, the display 208 includes an electronic display capable of outputting visual data to a user. For example, the display 208 may include (but is not limited to) a liquid crystal display ("LCD"), a light-emitting diode ("LED") display, an organic light-emitting diode ("OLED") display, a projector, or a similar display device capable of outputting images, text, etc. to a user.

[0042] In some embodiments, the display 208 includes one or more speakers for generating sound. For example, the display 208 can generate an audible alert or notification (e.g., a beep or a buzz). In some embodiments, the display 208 includes one or more haptic devices for generating vibration, movement, or other haptic feedback. In some embodiments, all or part of the display 208 can be integrated with the input device 206. For example, the input device 206 and the display 208 can form a touch screen or a similar touch-sensitive display. In other embodiments, the display 208 can be located near the input device 206.

[0043] In some embodiments, the receiver 212 can: receive first information indicating a first set of transmission configuration indicator states from at least one network device; and receive second information indicating a second set of transmission configuration indicator states from at least one network device. In various embodiments, the processor 202 can: determine an association between the first set of transmission configuration indicator states and a first set of transmission opportunities; and determine an association between the second set of transmission configuration indicator states and a second set of transmission opportunities.

[0044] Although only one transmitter 210 and one receiver 212 are illustrated, the remote unit 102 can have any suitable number of transmitters 210 and receivers 212. The transmitters 210 and receivers 212 can be any suitable type of transmitters and receivers. In one embodiment, the transmitters 210 and receivers 212 can be part of a transceiver.

[0045] Figure 3 An embodiment of a device 300 that can be used for transmission configuration indicator state association is depicted. The device 300 includes an embodiment of a network unit 104. Additionally, the network unit 104 can include a processor 302, a memory 304, an input device 306, a display 308, a transmitter 310, and a receiver 312. As can be appreciated, the processor 302, the memory 304, the input device 306, the display 308, the transmitter 310, and the receiver 312 can be generally similar to the processor 202, the memory 204, the input device 206, the display 208, the transmitter 210, and the receiver 212 of the remote unit 102, respectively.

[0046] In various embodiments, multi-TRP communication can be used for physical downlink shared channel (“PDSCH”) transmissions with increased reliability. In some embodiments, only up to 2 TCI state indicators can be used, and the 2 TCI states can be associated with different transmission opportunities. In such embodiments, there may be limited support related to the number of beams and / or TRPs. Further, in such embodiments, a combination of transmissions in the spatial domain, the frequency domain, and / or the time domain can be used.

[0047] In some embodiments, compared to lower frequencies, for frequency range 2 (“FR2”) (24.25 GHz to 52.6 GHz), the number of beams and / or the number of TRPs at the network side and the number of panels at the UE side may be larger, and may be even larger for frequencies above FR2.

[0048] This document describes various enhancements to beam management for frequencies above 52.6 GHz, but also applies to FR2 below 52.6 GHz. In certain embodiments, the TCI signaling framework can be enhanced to support a higher degree of beamforming from multiple TRPs across different domains (e.g., transmit opportunities in FDM, spatial division multiplexing (“SDM”), and time division multiplexing (“TDM”)).

[0049] In various embodiments, a set of layers (e.g., up to 2 layers) for a single transmit opportunity can transmit using only a single TCI state from a demodulation reference signal (“DMRS”) port within a single CDM group. In some embodiments, e.g., for frequencies above 52.6 GHz, more than 2 TCI states can be used.

[0050] In certain embodiments, TCI signaling can enable implicit or explicit grouping of TCI states, and TCI groups (and the states within the groups) can be associated with transmit opportunities from single and / or multiple TRPs using a combination of spatial domain, frequency domain, and / or time domain multiplexing.

[0051] The various embodiments described herein enable a flexible combination of multi-beam transmissions from single and / or multiple TRPs, with a higher degree of spatial relationship compared to other configurations (e.g., for use in NR).

[0052] In some embodiments, multiple TCI state groups (“TSGs”) can be used by a network entity (e.g., gNB) for a UE via transmit configuration to the UE. In such embodiments, a TCI state group (“TSG”) can contain up to ‘N’ TCI states. Additionally, the gNB can configure multiple DL TX beam combinations (e.g., TSGs) based on the UE's CSI report and / or the gNB's knowledge of the DL TX beam pattern and TRP deployment. The gNB can dynamically indicate up to ‘M’ TSGs via the TCI code point in the DCI. Further, the TCI code point can be mapped to one or more TSGs (e.g., up to ‘M’ TSGs).

[0053] In certain embodiments, the gNB semi-statically configures a set of TSGs, and a MAC control element (“CE”) is used to activate a subset of the set of TSGs by combining one or more TSGs from each index of the semi-statically configured TCI code points. The DCI can signal an index of the TCI code point.

[0054] In various embodiments, the TSG may have a single TCI state, and the number of TCI states in each configured TSG may be different. In such embodiments, the UE may receive multiple DMRS antenna port indications (e.g., up to 'N' indications) in the DCI. Each DMRS antenna interface indication among the multiple DMRS antenna port indications may be applicable to one or more TSGs having a specific number of TCI states. For example, the gNB may signal two DMRS antenna port indications in the DCI (e.g., one for a TSG having a single TCI state and another for a TSG having two TCI states).

[0055] In some embodiments, the TCI states within a TSG may correspond to spatial beams of different TRPs. In certain embodiments, the TCI states within TSG j may correspond to the spatial beams associated with TRP j.

[0056] In some embodiments, the activation and / or deactivation of enhanced TCI state groups for UE-specific PDSCH MAC CE may be identified by a MAC protocol data unit ("PDU") sub-header with a logical channel identifier ("LCID"). The MAC CE may have a variable size and includes the following fields: 1) Serving cell ID: This field indicates the identity of the serving cell to which the MAC CE applies - the length of this field is 5 bits; 2) Bandwidth part ("BWP") ID: This field indicates the DL BWP to which the MAC CE applies as the code point of the DCI bandwidth part indicator field - the length of the BWP ID field is 2 bits; 3) Ci,j: This field indicates whether there is an octet containing the TCI state group IDi,j+1 - if this field is set to "1", then there is an octet containing the TCI state group IDi,j+1, and if this field is set to "0", then there is no octet containing the TCI state group IDi,j+1; 4) TCI state group IDi,j: This field indicates the TCI state group identified by TCI-StateGroupId, where i is the code point index of the DCI transmission configuration indicator field, and TCI state group IDi,j represents the jth TCI state indicated by the ith code point in the DCI transmission setting indicator field - the TCI code point to which the TCI state group maps is determined by its sequential position among all TCI code points in the set with the TCI state group IDi,j field, i.e., the first TCI code point with TCI state group ID0,1, …, TCI state group ID0,J(0) should be mapped to code point value 0, the second TCI code point with TCI state group ID1,1, …, TCI state ID1,J(1) should be mapped to code point value 1, and so on, where J(i) represents the number of TCI state groups of the ith code point in the DCI transmission configuration indicator field - TCI state group IDi,2, …, TCI state group IDi,J(i) are optional based on the indication of the Ci,1, …, Ci,J(i)-1 fields - the maximum number of activated TCI code points is 8, and the maximum number of TCI state groups mapped to TCI code points is Jmax, where Jmax is configured by radio resource control ("RRC") or predefined; and 5) R: Reserved bit, which is set to "0".

[0057] Figure 4 FIG. 400 is a diagram illustrating an embodiment of the activation / deactivation of enhanced TCI state groups for UE-specific PDSCH MAC CE.

[0058] In various embodiments, the gNB may signal up to 'N' TCI states to the UE via a single index of the TCI code point in the DCI, and 'M-1' consecutive indexes adjacent to the signaled index of the active TCI table may be implied as being allocated and / or indicated to the UE. In such embodiments, if index n is signaled to the UE via the TCI code point in the DCI, then indexes n+1, n+2…, n+M-1 may be implied as being indicated to the UE (e.g., the TCI states corresponding to TCI code points n, n+1,, n+2…, n+M-1 may be indicated to the UE, or if the TCI state j indicated via the TCI code point in DCI-TCI states j+1, j+2…j+M-1 can be implicitly indicated to the UE).

[0059] In some embodiments, the value of M may be explicitly configured or indicated by the gNB to the UE such that the index n+M-1 is less than or equal to the highest index of the TCI table. In certain embodiments, the value of M may be inferred from the number of transmission opportunities separately configured or indicated by the gNB to the UE. In various embodiments, the value of M (e.g., Mi) may be configured for each TCI code point i.

[0060] In certain embodiments, the gNB may signal up to 'N' TCI states to the UE via a single index of the TCI code point in the DCI, and 'M-1' consecutive indexes adjacent to the signaled index of the active TCI table may be implied as being allocated and / or indicated to the UE. In such embodiments, if index n is signaled to the UE via the TCI code point in the DCI, then indexes n-1, n-2…, n-M+1>=0 may be implied as being indicated to the UE (e.g., the TCI states corresponding to TCI code points n, n-1, n-2…, n-M+1 may be indicated to the UE, or if the TCI state j indicated via the TCI code point in DCI-TCI states j-1, j-2,…j-M+1 can be implicitly indicated to the UE).

[0061] In various embodiments, the value of M may be explicitly configured or indicated by the gNB to the UE, and index n may be signaled such that the index n-M+1 is greater than or equal to the lowest index of the TCI table (e.g., 0). In some embodiments, the value of M may be inferred from the number of transmission opportunities separately configured or indicated by the gNB to the UE. In certain embodiments, if index n is indicated to the UE, then all indexes from 0 to n may be implied as having been indicated to the UE.

[0062] In some embodiments, the gNB may signal up to 'N' TCI states to the UE via a single index of the TCI code point in the DCI, and these 'N' TCI states may be grouped such that each group contains 'K' TCI states, where 'K' is equal to the number of DM-RS code division multiplexing ("CDM") groups signaled by the antenna port field.

[0063] In some embodiments, the gNB may signal up to 'N' TCI states to the UE via a single index of the TCI code point in the DCI, and these 'N' TCI states may be grouped into 'M' groups such that each group may contain a different number of TCI states.

[0064] In certain embodiments, the UE may configure multiple TCI states for the TCI code point i in the TCI table - the TCI state IDi,j represents the jth TCI indicated by the ith code point. In one example, for the ith code point, M TSGs may be formed such that TSGIDi,m where m = 0…M-1 contains the TCI states with TCI state IDk,j, where k = (i + m) mod N, and for all j, N = the number of code points in the TCI table (e.g., the TCI state corresponding to code point k forms a TSG with TSG IDi,m). In another example, for the ith code point, M TSGs may be formed such that TSG IDi,m where m = 0…M-1 contains the TCI states with TCI state IDk,j, where k = (i - m) mod N and for all j. In a further example, for the kth code point, M TSGs may be formed such that TSG IDi,m where m = 0…M-1 contains the TCI states with TCI state IDk,j, where k = (i + m - floor(M / 2)) mod N and for all j.

[0065] In various embodiments, if the UE is configured by a higher layer parameter PDSCH-config that indicates at least one entry in the pdsch-TimeDomainAllocationList containing RepNumR16 in PDSCH-TimeDomainResourceAllocation, then the UE may expect to use 'M <= RepNumR16' TSGs and the DM-RS ports in 'N' CDM groups in the DCI fields "time domain resource allocation" and "antenna port" in the pdsch-TimeDomainAllocationList that indicate the entries containing RepNum16 in PDSCH-TimeDomainResourceAllocation are explicitly or implicitly indicated, where 'N' is equal to the number of TCI states within a TSG. In one example, 'N' is equal to the maximum number of TCI states within one of the 'M' TSGs.

[0066] If the UE is indicated 'M = RepNumR16' TSGs and 'N > 1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same transmission block ("TB"), where there are 'N' transmission opportunities within one time slot and 'N x M' transmission opportunities across 'M' time slots. Each TSG can be associated with each time slot in a sequential manner, and each of the N TCI states within a TSG can be associated with the transmission opportunities within the time slot in a sequential manner. For time slot 'k' (e.g., k = m), the UE may expect to receive 'N' transmission opportunities (e.g., of the same TB) on the same time-frequency resource within the time slot, but on different receive beams and / or panels transmitted by the same TRP or 'N' different beams from different TRPs (e.g., associated with the TCI states within TSG'm'). Similarly, for the next time slot 'k + 1' (e.g., k = m), the UE may expect to receive another 'N' transmission opportunities (e.g., of the same TB) on the same time-frequency resource within the time slot, but on different receive beams and / or panels transmitted by the same TRP or 'N' different beams from different TRPs (e.g., associated with the TCI states within TSG'm + 1'). This transmission scheme can continue until the 'k + M - 1' time slot.

[0067] If the UE is indicated with 'M < RepNumR16' TSGs and 'N > 1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same TB, where there are 'N' transmission opportunities within one time slot and 'N x RepNumR16' transmission opportunities across 'RepNumR16' time slots. Each TSG can be associated with each time slot in a sequential manner (e.g., TSG#1#1#2#2 is associated with 4 time slots where RepNumR16 = 4 and M = 2), and each of the N TCI states within the TSG can be associated with the transmission opportunities within the time slot in a sequential manner. The 'M' TSGs can be associated with the time slots in a cyclic manner or some other configured and / or indicated pattern (e.g., using modulo M wrapping, the time slot 'k' associated with TSG k mod M, TSG#1#2#1#2 is associated with 4 time slots where RepNumR16 = 4 and M = 2).

[0068] If the number of TCI states (e.g., L) within the TSG for a time slot is less than N, then the TCI states of the TSG associated with the N transmission opportunities within the time slot can be determined in a sequential manner (e.g., TCI state#1#1#2#2 is associated with N = 4 transmission opportunities where L = 2), a cyclic manner (e.g., using modulo L wrapping, the transmission opportunity 't' associated with TCI state t mod L, TCI state#1#2#1#2 is associated with N = 4 transmission opportunities where L = 2), or some other configured and / or indicated pattern.

[0069] For the 'N' transmission opportunities within a time slot, the redundancy version to be applied can be derived based on the RV sequence redundancy version identifier ("RVID") indicated in the DCI as shown in Figure 5 where n = 0, 1,... (N - 1) mod 4 is applied to the first transmission opportunity, the second transmission opportunity within the time slot, and so on, up to the Nth transmission opportunity. The RV sequence offset relative to the indicated RV sequence can be applied to determine the RV sequence of the transmission opportunities associated with different time slots. For example, for time slot 'k' (k = 0, 1,... RepNumR16 - 1), the RV sequence offset rv5 = k * RWeqOffset, and Figure 6 can be used to determine the RV sequence of the transmission opportunities in time slot 'k', where RVSeqOffset is configured by the higher layer. Figure 5 FIG. 500 is an example diagram illustrating the indicated applied redundancy version 1. Figure 6 FIG. 600 is an example diagram illustrating the indicated applied redundancy version with RVSeqOffset.

[0070] In some embodiments, the 'N' TCI states within a TSG may correspond to a single transmission occasion within a time slot, but with 'N'-layer transmissions with 'N' different beams from the same or different TRPs. The redundancy version applied to the transmission occasion in time slot 'n' may be derived based on the DCI and Figure 5 the RV sequence RVID indicated in

[0071] In certain embodiments, if the UE is configured by a higher layer parameter RepSchemeEnabler set to 'FDMSchemeA' or 'FDMSchemeB', and the UE is configured by a higher layer parameter PDSCH-config indicating at least one entry in the pdsch-TimeDomainAllocationList containing RepNumR16 in PDSCH-TimeDomainResourceAllocation, then the UE may expect to use 'M <= RepNumR16' TSGs and the DM-RS ports within 'N' CDM groups indicated explicitly or implicitly by the DCI field "time domain resource allocation" and the DCI field "antenna port" of the entry in the pdsch-TimeDomainAllocationList containing RepNum16 in PDSCH-TimeDomainResourceAllocation, where 'N' is equal to the number of TCI states in the TSG. In one example, 'N' is equal to the maximum number of TCI states within the TSG among the 'M' TSGs.

[0072] If the UE is signaled with 'M = RepNumR16' TSGs and 'N > 1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same TB (e.g., using "FDMSchemeB") where there are 'N' transmission opportunities within one time slot and 'N x M' transmission opportunities across 'M' time slots. Each TSG may be associated with each time slot in a sequential manner, and each of the N TCI states within a TSG may be associated with the transmission opportunities within the time slot in a sequential manner. For time slot 'k' (e.g., k = m), the UE may expect to receive 'N' transmission opportunities (e.g., the same TB) on non-overlapping frequency-domain resources on different receive beams and / or panels, where the different receive beams or panels are transmitted by the same TRP or N different beams from different TRPs (e.g., associated with the TCI state within TSG'm'). Similarly, for the next time slot 'k + 1' (e.g., k = m), the UE may expect to receive another N transmission opportunities (e.g., the same TB) on non-overlapping frequency-domain resources on different receive beams and / or panels, where the receive beams and / or panels are transmitted by the same TRP or 'N' different beams from different TRPs (e.g., associated with the TCI state within TSG'm + 1'). This transmission scheme may continue up to the 'k + M - 1' time slot.

[0073] If the UE is signaled with 'M < RepNumR16' TSGs and 'N > 1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same TB, where there are 'N' transmission opportunities within one time slot and 'N x RepNumR16' transmission opportunities across 'RepNumR16' time slots. Each TSG may be associated with each time slot in a sequential manner, and each of the N TCI states within a TSG may be associated with the transmission opportunities within the time slot in a sequential manner. The 'M' TSGs may be associated with the time slots in a cyclic manner or some other configured and / or indicated pattern.

[0074] If the number of TCI states (e.g., L) within the TSG for a time slot is less than N, then the TCI states of the TSG associated with the N transmission opportunities within the time slot may be determined in a sequential manner (e.g., TCI state #1#1#2#2 associated with N = 4 transmission opportunities where L = 2), a cyclic manner (e.g., using modulo L wrap-around, transmission opportunity 't' associated with TCI state t mod L, TCI state #1#2#1#2 associated with N = 4 transmission opportunities where L = 2), or some other configured and / or indicated pattern.

[0075] For the 'N' transmission opportunities within a time slot, the redundancy version to be applied is derived according to the RV sequence RVID indicated in the DCI (e.g.,Figure 5 ), where n = 0, 1, … (N-1) mod 4 is applied to the first transmission occasion, the second transmission occasion within the time slot, and so on, up to the Nth transmission occasion. An RV sequence offset relative to the indicated RV sequence can be applied to determine the RV sequence for the transmission occasions associated with different time slots (e.g., for time slot 'k' (k = 0, 1, … RepNumR16-1), the RV sequence offset rv s = k * RVSeqOffset, and Figure 6 the RV sequence for determining the transmission occasion in time slot 'k', where RVSeqOffset is configured by a higher layer).

[0076] In some embodiments, the 'N' TCI states within a TSG can correspond to a single transmission occasion within a time slot (e.g., using 'FDMSchemeA'), but have 'N' non-overlapping frequency domain resources associated with the TCI states within TSG'm', where the 'N' non-overlapping frequency domain resources are received on different receive beams and / or panels and transmitted by the same TRP or by N different beams from different TRPs. The redundant version applied to the transmission occasion in time slot 'n' can be derived based on the DCI and Figure 5 the RV sequence RVID indicated therein.

[0077] In some embodiments, if the UE is configured by a higher layer parameter RepSchemeEnabler set to 'TDMSchemeA' and the UE is configured by a higher layer parameter PDSCH-config indicating at least one entry in the pdsch-TimeDomainAllocationList containing RepNumR16 in PDSCH-TimeDomainResourceAllocation, then the UE may expect to use 'M <= RepNumR16' TSGs and the DM-RS ports in the 'N' CDM groups in the DCI fields "Time domain resource allocation" and "Antenna port" in the pdsch-TimeDomainAllocationList entries containing RepNum16 in PDSCH-TimeDomainResourceAllocation, either explicitly or implicitly indicated, where 'N' is equal to the number of TCI states within a TSG. In one example, 'N' is equal to the maximum number of TCI states within one of the 'M' TSGs.

[0078] If the UE is indicated 'M = RepNumR16' TSGs and 'N>1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same TB, where there are 'N' transmission opportunities within one time slot and 'N x M' transmission opportunities across 'M' time slots. Each TSG may be associated with each time slot in a sequential manner, and each of the N TCI states within the TSG may be associated with the transmission opportunities within the time slot in a sequential manner. For time slot 'k' (e.g., k = m), the UE may expect to receive 'N' transmission opportunities (e.g., the same TB) on non-overlapping time-domain resources on different receive beams and / or panels, with the different receive beams or panels transmitted by the same transmit and receive point ("TRP") or 'N' different beams from different TRPs (e.g., associated with the TCI state within TSG'm'). Similarly, for the next time slot 'k+1', the UE may expect to receive another 'N' transmission opportunities (e.g., the same TB) on non-overlapping time-domain resources on different receive beams and / or panels, with the receive beams and / or panels transmitted by the same TRP or 'N' different beams from different TRPs (e.g., associated with the TCI state within TSG'm+1'). This transmission scheme continues until the 'k+M-1' time slot.

[0079] If the UE is indicated 'M < RepNumR16' TSGs and 'N>1' DM-RS CDM groups (e.g., TCI states within each TSG), then the UE may expect to receive the same TB, where there are 'N' transmission opportunities within one time slot and 'N x RepNumR16' transmission opportunities across 'RepNumR16' time slots. Each TSG may be associated with each time slot in a sequential manner, and each of the N TCI states within the TSG may be associated with the transmission opportunities within the time slot in a sequential manner. The 'M' TSGs may be associated with the time slots in a cyclic manner or some other configured and / or indicated pattern.

[0080] If the number of TCI states (e.g., L) within the TSG for a time slot is less than N, then the TCI states of the TSG associated with the 'N' transmission opportunities within the time slot may be determined in a sequential manner (e.g., TCI state #1#1#2#2 is associated with 'N = 4' transmission opportunities where L = 2), a cyclic manner (e.g., using modulo L wrapping, the transmission opportunity 't' is associated with TCI state t mod L, TCI state #1#2#1#2 is associated with 'N = 4' transmission opportunities where L = 2), or some other configured and / or indicated pattern.

[0081] For the 'N' transmission opportunities within a time slot, according to the RV sequence RVID indicated in the DCI (e.g., Figure 5)Derive the redundancy versions to be applied, where n = 0, 1, … (N-1) mod 4 is applied to the first transmission occasion, the second transmission occasion within a time slot, and so on, up to the Nth transmission occasion. An RV sequence offset relative to the indicated RV sequence may be applied to determine the RV sequences for the transmission occasions associated with different time slots (for time slot 'k', k = 0, 1, … RepNumR16-1), the RV sequence offset rv s = k * RVSeqOffset, and Figure 6 can be used to determine the RV sequence for the transmission occasion in time slot 'k', where RVSeqOffset is configured by the higher layers.

[0082] In various embodiments, the N transmission occasions within a time slot may be associated with one TCI state from N TSGs (e.g., the N = 2 transmission occasions in the first time slot may be associated with the lowest-index TCI state from the first TSG and the lowest-index TCI state from the second TSG, and the N = 2 transmission occasions in the second time slot may be associated with the next lowest-index (e.g., lowest-index + 1) TCI state from the first TSG and the next lowest-index TCI state from the second TSG), rather than with N TCI states of the TSGs. In one example, 'N' is equal to the number of TSGs. If the number of TCI states within a TSG is less than the number of time slots, then sequential or cyclic mapping may be used.

[0083] The embodiments described herein may be applicable to downlink transmissions (e.g., PDSCH from a network node to a UE), uplink transmissions (e.g., physical uplink shared channel (“PUSCH”) from a UE to a network node), or sidelink transmissions (e.g., physical sidelink shared channel (“PSSCH”) from a first UE to a second UE). For transmissions from a UE, the TCI state may correspond to an uplink and / or sidelink TCI state or spatial relationship. The UE may be able to perform simultaneous transmissions associated with multiple TCI states using one or more RF chains, antenna arrays, antenna sub-arrays, and / or antenna panels.

[0084] In some embodiments, a first set of TCI states is associated with a first set of transmission occasions. In such embodiments, the first set of transmission occasions is a downlink transmission, and a second set of TCI states is associated with a second set of transmission occasions. Additionally, the second set of transmission occasions is an uplink transmission.

[0085] In some embodiments, the first set of TCI states associated with downlink transmissions and the second TCI states associated with uplink transmissions are indicated by a single TCI code point.

[0086] In some embodiments, a first set of TCI states associated with downlink transmissions and a second set of TCI states associated with uplink transmissions are indicated by two separate TCI code points.

[0087] In some embodiments, an antenna port may be defined such that the channel over which a symbol is conveyed on the antenna port can be inferred from the channel over which another symbol is conveyed on the same antenna port.

[0088] In certain embodiments, if the large-scale properties of the channel over which a symbol is conveyed on one antenna port can be inferred from the channel over which a symbol is conveyed on another antenna port, then the two antenna ports are said to be quasi co-located (“QCL”). The large-scale properties may include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and / or spatial receive (“RX”) parameters. Two antenna ports may be quasi co-located with respect to a subset of the large-scale properties, and different subsets of the large-scale properties may be indicated by QCL types. For example, the qcl type may take on one of the following values: 1) 'QCL-Type A': {Doppler frequency shift, Doppler spread, average delay, delay spread}; 2) 'QCL-Type B': {Doppler frequency shift, Doppler spread}; 3) 'QCL-Type C': {Doppler frequency shift, average delay}; and 4) 'QCL-Type D': {spatial Rx parameters}.

[0089] In various embodiments, the spatial RX parameters may include one or more of the following: angle of arrival (“AoA”), dominant AoA, average AoA, angular spread, power angular spectrum (“PAS”) of the AoA, average angle of departure (“AoD”), PAS of the AoD, transmit and / or receive channel correlation, transmit and / or receive beamforming, and / or spatial channel correlation.

[0090] In some embodiments, an “antenna port” may be a logical port that may correspond to a beam (e.g., generated by beamforming), or may correspond to a physical antenna on a device. In certain embodiments, a physical antenna may be directly mapped to a single antenna port, where the antenna port corresponds to the actual physical antenna. In various embodiments, after applying complex weights and / or cyclic delays to the signals on each physical antenna, a set of physical antennas, a subset of physical antennas, a set of antennas, an antenna array, or an antenna subarray may be mapped to one or more antenna ports. The set of physical antennas may have antennas from a single module or panel or from multiple modules or panels. The weights may be fixed as in an antenna virtualization scheme (e.g., cyclic delay diversity (“CDD”)). The process for deriving antenna ports from physical antennas may be specific to the device implementation and transparent to other devices.

[0091] In some embodiments, a UE antenna panel may be a physical or logical antenna array, comprising a set of antenna elements or antenna ports (e.g., in-phase and / or quadrature (“I / Q”) modulators, analog-to-digital (“A / D”) converters, local oscillators, phase shift networks) that share a common or significant portion of a radio frequency (“RF”) chain. The UE antenna panel or UE panel may be a logical entity having physical UE antennas mapped to logical entities. The mapping of physical UE antennas to logical entities may depend on the UE implementation. Communicating (e.g., receiving or transmitting) on at least a subset of the antenna elements or antenna ports of the antenna panel that are actively used for radiating energy (e.g., active elements) may require biasing or powering on the RF chain, which results in current consumption or power consumption in the UE associated with the antenna panel (e.g., including power amplifier and / or low noise amplifier (“LNA”) power consumption associated with the antenna elements or antenna ports). As used herein, the phrase “actively used for radiating energy” is not meant to be limited to the transmit function, but also encompasses the receive function. Thus, an antenna element actively used for radiating energy may be coupled to a transmitter to transmit radio frequency energy, or to a receiver to receive radio frequency energy, or generally may be coupled to a transceiver to perform its desired function. Communication on the active elements of the antenna panel enables the generation of a radiation pattern or beam.

[0092] In certain embodiments, depending on the UE's own implementation, the “UE panel” may have at least one of the following functions: independently controlling its transmit (“TX”) beam as an antenna group unit, independently controlling its transmit power as an antenna group unit, and / or independently controlling its transmit timing as an antenna group unit. The “UE panel” may be transparent to the gNB. For certain conditions, the gNB or network may assume that the mapping between the physical antennas of the UE and the logical entity “UE panel” may not change. For example, the conditions may include until the next update or report from the UE, or include a duration during which the gNB assumes the mapping will not change. The UE may report its UE capabilities regarding the “UE panel” to the gNB or network. The UE capabilities may at least include the number of “UE panels”. In one embodiment, the UE may support UL transmission from one beam within a panel. For multiple panels, more than one beam (e.g., one beam per panel) may be used for UL transmission. In another embodiment, more than one beam per panel may support and / or be used for UL transmission.

[0093] In various embodiments, a transmission configuration indicator ("TCI") state associated with a target transmission may indicate a quasi - co - location relationship between the target transmission (e.g., the target RS of the demodulation reference signal ("DM - RS") port of the target transmission during a transmission occasion) and a source reference signal (e.g., a synchronization signal block ("SSB"), a channel state information reference signal ("CSI - RS"), and / or a sounding reference signal ("SRS")) with respect to the quasi - co - location type parameters indicated in the corresponding TCI state. A UE may receive a configuration of multiple transmission configuration indicator states of a serving cell for transmissions on the serving cell.

[0094] In some embodiments, the spatial relationship information associated with a target transmission may indicate the spatial arrangement between the target transmission and a reference RS (e.g., SSB, CSI - RS, and / or SRS). For example, a UE may use the same spatial domain filter for receiving a reference RS (e.g., DL RS (e.g., SSB and / or CSI - RS)) to transmit the target transmission. In another example, a UE may use the same spatial domain transmission filter for transmitting an RS (e.g., UL RS (e.g., SRS)) to transmit the target transmission. A UE may receive a configuration of multiple spatial relationship information of a serving cell for transmissions on the serving cell.
