BRIEF DESCRIPTION OF THE DRAWINGS A more specific description of the modalities briefly described in the previous section, with reference to specific modalities illustrated in the accompanying drawings, follows. Understanding that these drawings represent only some modalities and therefore should not be considered limiting in scope, the modalities will be described and explained with additional specificity and detail through the use of the accompanying drawings. FIGURE 1 is a schematic block diagram illustrating one mode of a wireless communication system for configuring uplink transmission configuration indication states. FIGURE 2 is a schematic block diagram illustrating one modality of an apparatus that can be used to configure uplink transmission configuration indication states. FIGURE 3 is a schematic block diagram illustrating one mode of an apparatus that can be used to configure uplink transmission configuration indication states.

FIGURE 5 is a flowchart illustrating one modality of a method for configuring uplink transmission configuration indication states. FIGURE 6 is a flowchart that illustrates another form of a method for configuring uplink transmission configuration indication states. DETAILED DESCRIPTION OF THE INVENTION As someone skilled in the art will appreciate, some aspects of modalities can be materialized in the form of a system, apparatus, method, or program product. Accordingly, modalities can take the form of an entirely hardware modality, an entirely software modality (including firmware, resident software, microcode, etc.), or a modality that combines software and hardware aspects, which, in general, may be referred to herein as a “circuit,” “module,” or “system.” Additionally, modalities can take the form of a program product embedded in one or more computer-readable storage devices that store machine-readable code, computer-readable code, and / or program code, hereinafter referred to as code. The storage devices may be tangible, non-transient, and / or non-transient. RORnnn / C7n7 / B / viAi transmission. Storage devices may not contain signals. In a certain mode, storage devices only use signals to access the code. Some of the functional units described in this specification can be labelled as modules to further emphasize their implementation independence. For example, a module can be implemented as a hardware circuit comprising very-large-scale integration (VLSI) circuits or custom gate arrays, commercial semiconductors such as logic chips, transistors, or other discrete components. Alternatively, a module can be implemented on programmable hardware devices, such as field-programmable gate arrays, programmable logic arrays, programmable logic devices, or similar devices. Modules can also be implemented in code and / or software for execution by various types of processors. For example, an identified code module may include one or more physical or logical blocks of executable code, which may be organized as an object, procedure, or function. However, the executables of an identified module do not need to be physically located together; they may include disparate instructions stored in different locations that, when logically combined, comprise the module and achieve its intended purpose. In fact, a code module can be a single instruction, or many instructions, and can even be distributed across several different code segments, among different programs, and across various memory devices. Similarly, operational data can be identified and illustrated within modules, and can be incorporated in any suitable form and organized within any suitable type of data structure. Operational data can be collected as a single data set, or it can be distributed across different locations, including different computer-readable storage devices. When a module or parts of a module are implemented in software, the software components are stored on one or more computer-readable storage devices. Any combination of one or more computer-readable media may be used. The computer-readable medium may be a computer-readable storage medium. The computer-readable storage medium may be a storage device that stores the code. The storage device may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor system, apparatus, or device, or any suitable combination thereof. More specific examples (a non-exhaustive list) of storage devices would include the following: an electrical connection having one or more wires, a laptop floppy disk, a hard disk drive, random access memory (“RAM”), read-only memory (“ROM”), erasable programmable read-only memory (“EPROM” or Flash memory), a portable compact disc (“CD-ROM”), an optical storage device, a magnetic storage device, or any suitable combination thereof. In the context of this document, a computer-readable storage medium may be any tangible medium capable of containing or storing a program for use by or in connection with an instruction-execution system, apparatus, or device. The code to perform the operations of the modalities can have any number of lines and can be written in any combination of one or more programming languages, including an object-oriented programming language, such as Python, Ruby, Java, Smalltalk, C++, or similar, and conventional procedural programming languages, such as the C programming language or similar, and / or machine languages, such as assembly languages. The code can be executed entirely on the user's computer, partially on the user's computer as a standalone software package, partially on the user's computer and partially on a remote computer, or entirely on the remote computer or server.In the latter case, the remote computer can be connected to the user's computer through any type of network, including a local area network (“LAN”) or a wide area network (“WAN”), or the connection can be made to an external computer (for example, via the Internet using an Internet service provider). Reference throughout this specification to “a modality” or similar language means that a particular feature, structure, or characteristic described in relation to the modality is included in at least one modality. Therefore, the expressions “in a modality,” “in a modality,” and similar expressions throughout this specification may, but do not necessarily, refer to the same modality, but mean “one or more, but not all, modalities” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and their variations mean “including but not limited to,” unless expressly specified otherwise. An enumeration of items does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. The terms “a,” “one,” and “the” also mean “one or more,” unless expressly specified otherwise. Additionally, the described features, structures, or characteristics of the modalities can be combined in any suitable way. The following description provides numerous specific details, such as programming examples and modules. RORnnn / C7n7 / B / viAi software, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., are used to provide a comprehensive understanding of the modalities. However, a person skilled in the art will recognize that the modalities can be implemented without one or more of the specific details, or with other methods, components, materials, etc. In other cases, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of a modality. The following describes aspects of the modalities with reference to schematic flowcharts and / or schematic block diagrams of methods, devices, systems, and program products according to the modalities. It is understood that each block in 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, which are executed through the processor of the computer or other programmable data processing device, create means to implement the functions / actions specified in the block or blocks of the schematic flowcharts and / or schematic block diagrams. The code can also be stored on a storage device that can direct a computer, other programmable data processing apparatus, or other devices to function in a certain way, such that the instructions stored on the storage device produce a manufactured item that includes instructions implementing the function / act specified in the schematic flow diagrams and / or block schematic diagrams. The code can also be loaded into a computer, other programmable data processing device, or other devices to cause a series of operational steps to be executed on the computer, other programmable device, or other devices to produce a computer-implemented process such that the code that runs on the computer or other programmable device provides processes to implement the functions / acts specified in the flowchart and / or block or blocks of the block diagram. The schematic flowcharts and / or schematic block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of devices, systems, methods, and program products according to various modalities. In this respect, each block in the schematic flowcharts and / or schematic block diagrams can represent a module, segment, or portion of code, which includes one or more executable code instructions to implement the specified logical functions. It should also be noted that, in some alternative implementations, the functions indicated in the block may occur out of the order shown in the figures. For example, two blocks shown in succession may, in fact, execute substantially simultaneously, or the blocks may sometimes execute in reverse order, depending on the functionality involved. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more blocks, or parts thereof, in the illustrated figures. Although various types of arrows and lines may be used in flowcharts and / or block diagrams, it is understood that they do not limit the scope of the corresponding modes. In fact, some arrows or other connectors may be used solely to indicate the logical flow of the mode represented. For example, an arrow may indicate a waiting or control period of indeterminate duration between the numbered steps of the represented mode. It will also be noted that each block in block diagrams and / or flowcharts, and combinations of blocks in block diagrams and / or flowcharts, may be implemented by systems based on special-purpose hardware that perform the specified functions or actions, or by combinations of special-purpose hardware and code. The description of the elements in each figure may refer to elements in subsequent figures. Similar numbers refer to similar elements in all figures, including alternative forms of similar elements. Figure 1 depicts one mode of a wireless communication system 100 for configuring uplink transmission configuration indication states. In one mode, the wireless communication system 100 includes remote units 102 and network units 104.

In some embodiments, remote units 102 include wearable devices such as smartwatches, fitness trackers, head-mounted optical displays, or similar devices. Alternatively, remote units 102 may be referred to as subscriber units, mobile units, mobile stations, users, terminals, mobile terminals, fixed terminals, subscriber stations, UE, user terminals, a device, or by other terminology used in the art.Remote units 102 can communicate directly with one or more of the network units 104 using UL communication signals and / or remote units 102 can communicate directly with other remote units 102 using sidelink communication. 104 network units may be distributed across a geographic region. In certain configurations, a 104 network unit may also be called an access point, access terminal, base station, base station, Node-B, eNB, gNB, home Node-B, RAN, relay node, device, network device, IAB node, donor IAB node, or any other terminology used in the art. 104 network units are generally part of a radio access network that includes one or more controllers communicably coupled to one or more corresponding 104 network units. The radio access network is generally communicably coupled to one or more core networks, which may be coupled to other networks, such as the Internet and public switched telephone networks, among others. These and other elements of radio access and core networks are not illustrated, but are generally well known to those with ordinary knowledge of the art. In one implementation, the Wireless 100 communication system is compatible with the 5G or NG (Next Generation) standard of the 3GPP protocol, where the network unit 104 transmits using NG RAN technology. More generally, however, the Wireless 100 communication system can implement other open or proprietary communication protocols, such as WiMAX, among others. This description is not intended to be limited to the implementation of any particular wireless communication system architecture or protocol. Network units 104 can serve a number of remote units 102 within a service area, such as a cell or cell sector, via a wireless communication link. Network units 104 transmit DL communication signals to serve the remote units 102 in the time, frequency, and / or space domains. In various modes, a remote unit 102 can receive a radio resource control message that configures a set of uplink transmission configuration indication states, wherein each uplink transmission configuration indication state of the set of uplink transmission configuration indication states defines at least one uplink spatial relationship, wherein each uplink spatial relationship of the at least one uplink spatial relationship corresponds to a space domain transmission filter corresponding to a channel status information reference signal, a synchronization signal block, or a polling reference signal.In certain modes, remote unit 102 can receive a media access control element message comprising information that activates a subset of the uplink transmission configuration indication set for use in an uplink transmission configuration indication field of downlink control information used to schedule a codebook-based physical uplink shared channel transmission. In some modes, remote unit 102 can receive downlink control information with the uplink transmission configuration indication field indicating at least one uplink spatial relationship for the user equipment to use in the codebook-based physical uplink shared channel transmission.In various modes, the remote unit 102 can transmit the physical uplink shared channel transmission based on the codebook, with at least one uplink spatial relationship indicated by the uplink transmission configuration indication field in the downlink control information. Therefore, a remote unit 102 can be used to configure uplink transmission configuration indication states. In some modes, a 104 network unit can transmit a radio resource control message that configures a set of uplink transmit configuration indication states, wherein each uplink transmit configuration indication state of the set of uplink transmit configuration indication states defines at least one uplink spatial relationship, wherein each uplink spatial relationship of the at least one uplink spatial relationship corresponds to a space domain transmit filter corresponding to a channel state information reference signal, a synchronization signal block, or a polling reference signal.In certain modes, network unit 104 can transmit a media access control element message comprising information that activates a subset of the uplink transmission configuration indication set for use in a downlink control information uplink transmission configuration indication field used to schedule a codebook-based physical uplink shared channel transmission.

RORnnn / cznz / B / YiAi of uplink transmission configuration that indicates at least one uplink spatial relationship for the user equipment to use in the codebook-based physical uplink shared channel transmission. In some modes, network unit 104 can receive the codebook-based physical uplink shared channel transmission with at least one uplink spatial relationship indicated by the uplink transmission configuration indication field in the downlink control information. Consequently, a network unit 104 can be used to configure uplink transmission configuration indication states.

In some configurations, the 208 display includes one or more haptic devices to produce vibrations, movement, or other haptic feedback. In some configurations, all or part of the 208 display may be integrated with the 206 input device. For example, the 206 input device and the 208 display may form a touchscreen or similar touchscreen. In other configurations, the 208 display may be located near the 206 input device. In various modes, the 212 receiver can: receive a radio resource control message that configures a set of uplink transmit configuration indication states, wherein each uplink transmit configuration indication state of the set of uplink transmit configuration indication states defines at least one uplink spatial relationship, wherein each uplink spatial relationship of the at least one uplink spatial relationship corresponds to a space domain transmit filter corresponding to a channel state information reference signal, a synchronization signal block, or a polling reference signal;receive a medium access control element message comprising information that activates a subset of the uplink transmission configuration indication state set for use in an uplink transmission configuration indication field of the downlink control information used to schedule a codebook-based physical uplink shared channel transmission;and receive downlink control information with the uplink transmission configuration indication field indicating at least one uplink spatial relationship for the user equipment to use in the codebook-based physical uplink shared channel transmission.

Additionally, Network Unit 104 may include a Processor 302, a Memory 304, an Input Device 306, a Display 308, a Transmitter 310, and a Receiver 312. As can be seen, the Processor 302, Memory 304, Input Device 306, Display 308, Transmitter 310, and Receiver 312 may be substantially similar to the Processor 202, Memory 204, Input Device 206, Display 208, Transmitter 210, and Receiver 212 of Remote Unit 102, respectively. In some modes, the 310 transmitter can: transmit a radio resource control message that configures a set of uplink transmit configuration indication states, wherein each uplink transmit configuration indication state in the set of uplink transmit configuration indication states defines at least one uplink spatial relationship, wherein each uplink spatial relationship in the at least one uplink spatial relationship corresponds to a corresponding space domain transmit filter RORnnn / C7n7 / B / viAi to a channel status information reference signal, a synchronization signal block, or a polling reference signal; transmit a medium access control control element message comprising information that activates a subset of the uplink transmission configuration indication set of states for use in an uplink transmission configuration indication field of the downlink control information used to program a codebook-based physical uplink shared channel transmission; and transmit the downlink control information with the uplink transmission configuration indication field indicating at least one uplink spatial relationship for use by user equipment in the codebook-based physical uplink shared channel transmission.In certain modes, the 312 receiver can receive the physical uplink shared channel transmission based on codebook with at least one uplink spatial relationship indicated by the uplink transmission configuration indication field in the downlink control information. Although only one 310 transmitter and one 312 receiver are illustrated, the 104 network unit can have any suitable number of 310 transmitters and 312 receivers. The 310 transmitter and 312 receiver can be any suitable type of transmitter and receiver. In one configuration, the 310 transmitter and 312 receiver can be part of a transceiver. In various modes, a PDSCH DL transmission beam can be indicated in DC11_1 or 1_2 format using a 3-bit TCI field. This indication allows a gNB to select between possible DL beams (for example, for single TRP transmission). In some modes, such as single DCI multi-TRP PDSCH transmissions, the TCI DL code points can be associated with two different TCI states, one for each TRP. In certain modes, a PUSCH UL transmit beam can be a property of SRS resources and can only be changed by changing an SRS resource indicated by an SRI field in DCI format 01 or 02. In various modes, such as for codebook-based PUSCH, a UE can be configured with one SRS resource set with a usage defined in the codebook. In such modes, the resource set of one SRS can contain two SRS resources with the same number of antenna ports. When these two SRS resources are configured with different spatialRelationInfo (e.g., spatial relationship information, configured spatial relationship information), a gNB can elect an ULTX beam by selecting SRI=0 or SRI=1. Each SRS resource can have its own spatial relationship information.Each SRS resource can have its spatialRelationlnfo configured by RRC to a CSI-RS, an SSB, or another SRS, and RRC reconfiguration can be used if the gNB decides to update the spatialRelationlnfo of an SRS resource. In some modes, to address a full-power UL transmission problem for UEs for which none of the TX power boosts can support full-power transmission (e.g., 23 dBm for Class 3 UEs), a UE can be configured with up to four different SRS resources with a different number of antenna ports. However, all four SRS resources can be determined by spatialRelationlnfo. In various modes, such as for non-codebook PUSCH transmission, a UL TX beam can be determined as part of SRI in a DCI field (for example, part of a property of SRS resources selected for PUSCH transmission). In certain modes, a UE can be configured with a single SRS resource set with a usage set to “nonCodebook”. The single SRS resource set can contain up to four single-port SRS resources. For a periodic or semi-persistent SRS resource set, a gNB can configure the SRS resource set via RRC with associatedCSI-RS. Consequently, all SRS resources can have the same UL TX beam determined by the associated CSI-RS. In such modes, the gNB can change the PUSCH UL TX beam by reconfiguring associatedCSI-RS with an RRC message. In some modes, such as for an aperiodic SRS resource set, each SRS resource can be configured with its own spatialRelationInfo.In such modes, up to four different UL TX beams can be configured and selected from an SRI field in DCL. Since a UE can only transmit with a single TX beam in PUSCH mode, if each SRS resource is configured with a different spatialRelationlnfo, only one of the SRS resources can be used, and the transmission range may be limited to one. To support up to a range of two, only two spatialRelationlnfo values ​​can be configured for four SRS resources. As can be seen, a trade-off between a flexible UL TX beam and transmission range can limit the use of multiple UL TX beams in PUSCH mode. In some modes, MIMO can support PUSCH transmission for multi-TRP. In certain modes, separate ULTX beams can be configured and used for PUSCH messages sent to different TRPs. In such modes, it can be transparent that PUSCH messages are sent to different TRPs in different locations. Additionally, more UL TX beams can be used to support multi-TRP PUSCH transmission. In various modes, the number of usable TX beams can be limited. In some modes, multiple UL TX beams can be used to support multi-TRP PUSCH transmission. In certain modes, such as codebook-based and non-codebook-based PUSCH, dynamic switching of a UL TX beam to a gNB beam may be limited compared to PDSCH. In various modes, to support multibeam communications, such as multi-TRP transmission, a flexible UL beam indication scheme can be used for PUSCH. In various modes, a PUSCH UL TX beam can be dynamically switched to a UE beam in codebook-based transmission. In some modes, to enable a flexible UL TX beam for PUSCH, a UL-TCI field in a DCI format can be used to dynamically designate a TX beam for codebook-based PUSCH transmission. In certain modes, if UL-TCI is enabled in a DCI format that programs a PUSCH, a number (for example, M) of UL-TCI states can be configured for a UE within a one-cell BWP per RRC. In such modes, each UL-TCI state can be associated with an RS that will be used as a space-domain TX filter for a UL TX beam. The RS can be a DL CSI-RS, a DL SSB, or a UL SRS. An example of a UL SRS might be an SRS resource for beam management. Of the M UL-TCI states, a subset can be activated for a UE with a MAC-CE message for use at any time.In various modes, a K-bit UL-TCI field (e.g., K=3) can be part of a DCI format (e.g., DCI format 0_1 ​​or 0_2) to indicate a UL TX beam that a UE should use for a transmission. In such modes, UL-TCI states of up to 2kA can be mapped to a UL-TCI code point in DCL. In various modes, if a UE receives a DCI format (e.g., DCI format 0_1 ​​or 0_2) with a UL-TCI field indicating an active UL-TCI state, the UE can apply the same space-domain TX filter of a UL beam indicated by the UL-TCI state (e.g., as defined in an associated DL RS or UL RS) to a PUSCH transmission. In some modes, although an SRS resource indicated by an SRI field in the same DCI may have its UL spatialRelationInfo set to RRC, a spatial domain TX filter indicated by a UL-TCI field may be used instead. In such modes, a precoder indicated by a TPMI field in the DCI may be applied to the SRS ports.In certain modes, if a DCI UL-TCI field points to a UL-TCI state that has not been activated by a MAC CE, a spatial TX filter from an SRS resource can be used as configured in its spatialRelationInfo.In various modes, the use of the default TX beam (e.g., reverting to the spatialRelationlnfo of an SRS if a UL-TCI state is not activated by MAC-CE) can be achieved by two methods: 1) if a gNB indicates a UL-TCI code point in DCI that is undefined or deactivated by MAC-CE, a UE can use the spatialRelationlnfo of the SRS resource indicated by an SRI field as the UL TX spatial filter; or 2) one of the UL-TCI code points (e.g., such as 0x7) can be reserved so that the gNB instructs the UE to use the spatialRelationlnfo of the SRS resource indicated by the SRI field as the UL TX spatial filter - the UE is not expected to receive a UL-TCI field in the DCI that points to a code point that is neither activated by MAC-CE nor the reserved value (e.g., 0x7). In some modes, if an SRS resource with usage=codebook is not configured with spatialRelationlnfo, a UE may use a spatial filter used to receive PDCCHs carrying DCI instead of its spatialRelationlnfo if it sends a PUSCH. In several modes, if the SRS resource with usage=codebook is not configured with spatialRelationlnfo, a UE uses a spatial filter that it uses to receive a more recent PDCCH from a CORESET or a CORESET with a lower ID instead of its spatialRelationlnfo if it sends a PUSCH. Figure 4 is a schematic block diagram of a 400 system illustrating one mode of a UL-TCI state configuration. The 400 system includes a first TRP 402 (“TRP1”), a second TRP 404 (“TRP2”), and a UE 406. The first TRP 402 communicates with the UE 406 via first communications 408, and the second TRP 404 communicates with the UE 406 via second communications 410. The first communications 408 can configure one or more of the following UL-TCI states: SRS1, SRS2, CSI-RS1, and CSI-RS2. The second communications 410 can configure one or more of the following UL-TCI states: SRS3, SRS4, CSI-RS3, and CSI-RS4. In Figure 4, a total of eight DL and UL TCI states are configured in RRC. Specifically, two CORESETPoolIndex values ​​(0 and 1) are configured for the CORESETs transmitted from TRP1 and TRP2. These CORESETPOOLIndex values ​​are used to distinguish the CORESETs transmitted from the TRPs for scheduling PUSCH transmissions. Additionally, PDCCH transmissions sent from TRP1 use CORESETs with CORESETPOOLIndex=0, and PDCCH transmissions sent from TRP2 use CORESETs with CORESETPOOLIndex=1. Furthermore, PUSCH is configured with txConfig=codebook. Additionally, in SRS-Config, a first set of SRS resources includes two SRS resources: {SRS1, SRS3} with usage=codebook. SRS1 and SRS3 are configured with spatialRelationlnfol and spatialRelationlnfo3, respectively. Additionally, there are two sets of SRS resources, each containing one SRS resource: {SRS2}, {SRS4} with usage=beamManagement. Furthermore, there are four CSI-RS resources {CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4}.Additionally, an RRC configuration of UL-TCI states 0 to 5 is configured with the following RS: {ULTCI-StateO: CSI-RS1}, {UL-TCI-State1: CSI-RS2}, {UL-TCI-State2: CSI-RS3}, {UL-TCI-State3: CSI-RS4}, {UL-TCI-State4: SRS2}, {UL-TCI-State5: SRS4}. In some modes, there are two ways to program PUSCH transmissions. In the first mode, the PUSCH can be programmed by each TRP individually and sent to the programming TRP via the corresponding UL beam. In the second mode, the PUSCH can be programmed by any TRP and sent to any TRP. The first mode can be used if the TRPs are connected by a non-ideal backhaul network and each TRP programs its own PUSCH transmissions. The second mode can be used if the TRPs are connected by an ideal backhaul network and a programming TRP dynamically decides whether the PUSCH transmissions are sent to any TRP, multiple TRPs, or all TRPs. In certain modes of the first mode, each TRP programs its own transmission PUSCH with its own DCI. The CORESETs transmitted by TRP1 and TRP2 can be configured with CORESETPOOLIndexO (for example, as illustrated in Table 1) and CORESETPOOLIndexl (for example, as illustrated in Table 2). In several modes, a set of UL-TCI states can be defined in RRC for a UE. For each CORESETPOOLIndex, a gNB sends a MAC-CE message (e.g., an activation message) to the UE to activate a set of UL-TCI states. The MAC-CE message includes a bit to indicate the corresponding CORESETPOOLIndex. After the UE receives a new MAC-CE message, it overwrites a previous setting. Based on the MAC-CE message received, for CORESETPOOLIndexO the UE 406 is configured with the UL-TCI states shown in Table 1, and for CORESETPOOLIndexl the UE 406 is configured with the UL-TCI states shown in Table 2. Table 1 UL-TCI Code Point for CORESETPOOLIndexO UL-TCI Status 0 CSI-RS1 1 CSI-RS2 2 SRS2 3-7 Not Configured Table 2 UL-TCI Code Point for CORESETPOOLIndexl UL-TCI Status 0 CSI-RS3 1 CSI-RS4 2 SRS4 3-7 Not Configured In some first-mode configurations, if TRP1 sends the UE 406 a DCI format (e.g., DCI 0_1 or 0_2) using a CORESET configured with CORESETPOOLIndexO, the UE 406 uses a spatial transmission filter corresponding to CSI-RS1, CSI-RS2, and / or SRS2 to send a PUSCH transmission if a UL-TCI field in DCI is 0, 1, or 2. Otherwise, the UE 406 uses a spatial transmission filter corresponding to the spatialRelationlnfo of the SRS resource indicated by an SRI field for the transmission. If SRI=0, the corresponding SRS resource is SRS1, and spatialRelationlnfo is used as the spatial transmission filter for a PUSCH transmission. In several first-mode configurations, if TRP2 sends the UE 406 a DCI format (e.g., DCI 0_1 or 0_2) using a CORESET configured with CORESETPOOLIndex, the UE 406 uses a spatial transmission filter corresponding to CSI-RS3, CSI-RS4, and / or SRS4 to send a PUSCH transmission if a UL-TCI field in the DCI is 0, 1, or 2. Otherwise, the UE 406 uses a spatial transmission filter corresponding to the spatialRelationInfo of the SRS resource indicated by an SRI field for the transmission. If SRI=1, the corresponding SRS resource is SRS3, and spatialRelationInfo3 is used as the spatial transmission filter for a PUSCH transmission. In certain modes of the first mode, the UE 406 uses spatialRelationlnfo from an SRS resource indicated by an SRI field only if the UL-TCI field in DCI is not configured (for example, 0x3, 0x4, 0x5, 0x6, 0x7) or is configured with a default value (for example, 0x7). In such modes, the UE 406 uses spatialRelationlnfo3 or spatialRelationlnfo3 as a spatial transmission filter for a PUSCH transmission if the CORESET on which the DCI is transmitted has a CORESETPOOLIndex configured as CORESETPOOLIndexO or CORESETPOOLIndexI, respectively. In some modes of the second mode, a single TRP transmits all PDCCH transmissions to UE 406. CORESETs carrying a PDCCH transmission are not configured with a CORESETPOOLIndex, or are all configured with CORESETPOOLIndexO. In one example, only a single set of UL-TCI states for UE 406 is activated by a MAC-CE message. Table 3 shows an example of UL-TCI code points activated by MAC-CE. Table 3 UL-TCI Code Point UL-TCI Status 0 CSI-RS1 1 CSI-RS2 2 CSI-RS3 3 CSI-RS4 4 SRS2 5 SRS4 6-7 Not Configured In several modes, if the UE 406 receives a DCI with UL-TCI=1, the UE 406 can use the same spatial domain filter it uses to receive CSI-RS2 as its spatial domain transmission filter for a PUSCH transmission. The PUSCH can then be sent to TRP1. If the UE 406 receives the DCI with UL-TCI=5, it can use the SRS4 spatial domain transmission filter to transmit the PUSCH to TRP2. In some modes, if the DCI is received with UL-TCI=7 and SRI=0, the UE 406 transmits the PUSCH transmission using the spatialRelationInfo3 spatial domain transmission filter. In some modes, if the DCI is received with UL-TCI=7 and SRI=1, the UE 406 transmits the PUSCH transmission using the spatialRelationInfo3 spatial domain transmission filter. In several modes, if a DCI is received with UL-TCI=7 and SRI=1, and the spatialRelationInfo for SRS3 is not configured, the UE 406 transmits the PUSCH transmission with an RX filter that the UE 406 uses for the CORESET for which the UE 406 receives the DCL. In this example, since the DCI is transmitted from TRP1, the PUSCH transmission is also sent to TRP1. In various configurations, a UL-TCI can define one, two, or more spatial UL relationships. Each spatial UL relationship can correspond to a space-domain transmission filter. For example, a UL-TCI can define a space-domain transmission filter for UE 406 to use in transmissions to both TRP1 (e.g., part of the first 408 communications) and TRP2 (e.g., part of the second 410 communications). In certain modes, it can take time for the UE 406 to prepare a TX beam for a PUSCH transmission. For a UE equipped with more than one panel, if the UE 406 needs to switch to another antenna panel to transmit with a new beam, the switchover time can be longer than if it didn't need to switch to another antenna panel. For example, let Td be the time from the last DCI symbol scheduling a PUSCH transmission to the first PUSCH symbol determined from a time-domain resource allocation field in the DCI, and let Ts be the time required for the UE 406 to switch transmit beams. In such an example, one or two Ts values ​​can be defined in terms of OFDM symbol duration for each subcarrier spacing for FR2 as a capacity of the UE transmitted from the UE to one or more TRPs.If two values ​​are provided for the UE capacity, the first value can be the time required for the UE 406 to prepare a transmit beam without switching to a different antenna panel (or SRS group), and the second value can be the time required for the UE 406 to prepare a transmit beam and switch to a different antenna panel. If a single value is provided for the user equipment capacity, that single value applies to cases with or without an antenna panel change. In certain modes, the UE 406 uses an appropriate value for Tscon based on a reported capacity and programming DCI. If TD <TS, el UE 406 puede no tener tiempo suficiente para preparar un filtro de transmisión espacial indicado por UL-TCL Si esto ocurre, el UE 406 puede aplicar spatialRelationlnfo de un recurso SRS indicado por un campo SRI en DCI incluso si el campo UL-TCI indica un estado UL-TCI válido (por ejemplo, activado).If TDsTs, the UE 406 can apply a space domain transmission filter indicated by the UL-TCI field, the SRS resource, or the PDCCH carrying the DCL. Figure 5 is a schematic flowchart illustrating one modality of a 500 method for configuring uplink transmission configuration indication states. In some modalities, a device performs the 500 method, such as remote unit 102. In certain modalities, the 500 method can be performed by a processor executing program code, for example, a microcontroller, a microprocessor, a CPU, a GPU, an auxiliary processing unit, an FPGA, or similar.

In some modes, Method 500 further comprises using a spatial domain filter that receives the downlink control information to transmit the uplink physical shared channel transmission based on a codebook if the spatial relationship information on the probe reference signal resource is not configured.In various forms, the 500 method also includes determining the spatial domain filter for physical uplink shared channel transmission based on a codebook based on a control resource set group index of a control resource set used to receive downlink control information.

In one embodiment, Method 500 further comprises notifying a network unit of a user equipment capability report, wherein the capability report comprises at least one time threshold value used to prepare at least one uplink spatial relationship for codebook-based physical uplink shared channel transmission. In certain embodiments, Method 500 further comprises determining at least one time threshold value based on downlink control information.In some modalities, Method 500 further comprises, in response to a time duration between downlink control information and codebook-based physical uplink shared channel transmission that is less than at least a time threshold, using spatial relationship information configured for a probe reference signal resource indicated by a probe reference signal resource index field of the downlink control information. Figure 6 is a schematic flowchart illustrating one modality of a 600 method for configuring uplink transmission configuration indication states. In some modalities, the 600 method is performed by a device, such as RORnnn / cznz / B / YiAi the network unit 104. In certain modalities, the 600 method can be carried out by a processor that executes program code, for example, a microcontroller, a microprocessor, a CPU, a GPU, an auxiliary processing unit, an FPGA, or the like. Method 600 may include transmitting 602 a radio resource control message that configures a set of uplink transmit configuration indication states, wherein each uplink transmit configuration indication state of the set of uplink transmit configuration indication states defines at least one uplink spatial relationship, wherein each uplink spatial relationship of the at least one uplink spatial relationship corresponds to a space domain transmit filter corresponding to a channel state information reference signal, a synchronization signal block, or a polling reference signal.In certain modes, Method 600 may include transmitting 604 a medium access control element message comprising information that activates a subset of the uplink transmission configuration indication set for use in an uplink transmission configuration indication field of downlink control information used to schedule a codebook-based physical uplink shared channel transmission.
