Abstract

Methods, systems, and devices for wireless communication are described. Some wireless communication systems can support dynamic uplink control channel packets. For example, a user equipment (UE) can receive control signaling indicating a plurality of uplink control channel groups for the UE, where each of the plurality of uplink control channel groups is associated with a different set of uplink control channel resources. Additionally, the UE can select an uplink control channel group for a component carrier (CC) associated with the UE, where the uplink control channel group is selected according to a detected trigger at the UE. In addition, the UE can transmit uplink control information for the CC according to the selected uplink control channel group.

Technical Field

[0003] The following relates to wireless communications, including dynamic uplink control channel grouping. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE). Summary of the invention

In general, the described technology allows a user equipment (UE) to select an uplink control channel group for a component carrier (CC) from a plurality of control channel groups based on a detected trigger at the UE. For example, the UE may receive control signaling indicating a plurality of control channel groups for the UE, wherein each uplink control channel group in the plurality of control channel groups is associated with a different set of uplink control channel groups. The UE may select an uplink control channel group for a CC associated with the UE, wherein the uplink control channel group is selected based on a detected trigger at the UE. In some cases, the detected trigger may be associated with receiving a second control signaling indicating an uplink control channel group for the CC or indicating an uplink control channel group configuration from a plurality of control channel group configurations associated with the plurality of uplink control channel groups. In some other cases, the detected trigger may be associated with a timer or counter associated with the plurality of uplink control channel groups. In some other cases, the detected trigger may be associated with a scheduling type associated with the CC.

[0052] Some wireless communication systems may support carrier aggregation, in which a user equipment (UE) may communicate with one or more network entities via multiple component carriers (CCs), each of which is associated with a set of frequency resources within a frequency band. In some cases, the UE may receive multiple downlink transmissions on each CC in the multiple CCs, and may send uplink control information, such as feedback information, for each downlink transmission received via each CC. In some examples, the UE may send uplink control information for one or more CCs according to an uplink control channel group. That is, one or more CCs may belong to an uplink control channel group, and the UE may send uplink control channel information for one or more downlink transmissions associated with the one or more CCs in a set of resources associated with the uplink control channel group (e.g., in a single transmission). In some examples, the UE may support multiple uplink control channel group configurations. For example, a first CC may belong to a first uplink control channel group according to a first uplink control channel group configuration, and may belong to a second uplink control channel group according to a second uplink control channel group configuration. In some cases, the first uplink control channel group may be applicable to reporting uplink control information (UCI) (e.g., feedback) of some types of data on the first CC, but not for other types of data. However, existing solutions do not allow the first CC to be dynamically switched between uplink control channel groups in response to rapid changes in the type of data sent on the first CC.

[0053] Thus, the techniques described herein may support dynamic uplink control channel grouping for one or more CCs associated with a UE. For example, a network entity may indicate to a UE a plurality of uplink control channel groups for the UE, wherein each of the plurality of control channel groups may be associated with a different set of uplink control channel resources. Additionally, the UE may select an uplink control channel group for a CC associated with the UE based on a detected trigger. For example, the UE may receive a control signaling including an indication of an uplink control channel group for the CC (e.g., an explicit indication, wherein the trigger is based on receiving the control signaling. In another example, the UE may select an uplink control channel group for the CC based on the expiration of a timer or the value of a counter exceeding a threshold. In some other examples, each of the plurality of uplink control channel groups may be associated with a corresponding uplink control channel group configuration, so that the UE may receive control signaling indicating an uplink control channel group configuration associated with the uplink control channel group for the CC, and the trigger may be based on receiving the control signaling. Thus, the UE may carry UCI for the CC according to the selected uplink control channel group.

[0054] Various aspects of the disclosure are first described in the context of a wireless communication system. Then, various aspects of the disclosure are described in the context of a scheduling configuration and process flow. Various aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to dynamic uplink control channel grouping.

[0055] Figure 1 An example of a wireless communication system 100 supporting dynamic uplink control channel grouping according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, a new radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0056] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0057] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1 . The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.

[0058] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0059] In some examples, the network entities 105 may communicate with the core network 130 or with each other or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3 or other interface protocols). In some examples, the network entities 105 may communicate with each other via the backhaul communication links 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0060] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0061] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0062] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functions, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165, such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functions and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functions and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0063] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0064] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support dynamic uplink control channel grouping as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0065] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0066] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 as shown in .

[0067] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink CCs and one or more uplink CCs according to the carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) CCs. Communication between the network entity 105 and other devices may refer to communication between these devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0068] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0069] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode).

[0070] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be configured to support communications using one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0071] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0072] One or more parameter sets for a carrier may be supported, and the parameter sets may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be constrained to one or more active BWPs.

[0073] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0074] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0075] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0076] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling via downlink carriers, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0077] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0078] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms "ultra-reliable", "low latency", and "ultra-reliable low latency" are used interchangeably herein.

[0079] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0080] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0081] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0082] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in conjunction with CCs operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0083] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0084] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0085] UE 115 and network entity 105 may support retransmission of data to increase the likelihood of data being successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received via a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0086] The wireless communication system 100 may support dynamic uplink control channel grouping. For example, the network entity 105 may send control signaling indicating multiple uplink control channel groups for the UE 115 to the UE 115, and each uplink control channel group may be associated with a different set of uplink control channel resources. For example, the UE 115 may be associated with multiple CCs (including a first CC, a second CC, and a third CC). Therefore, the control signaling from the network entity 105 may indicate a first uplink control channel associated with a first set of uplink control channel resources and a second uplink control channel group associated with a second set of uplink control channel resources. In some cases, each CC in the multiple CCs may belong to an uplink control channel group according to an uplink control channel group configuration. For example, a first uplink control channel group configuration may correspond to a first uplink control channel group including a first CC, a second CC, and a third CC, and a second uplink control channel group configuration may correspond to a first uplink control channel group including a first CC and a second CC and a second uplink control channel group including a third CC.

[0087] Additionally, the UE 115 may select an uplink control channel group for a CC (such as a first CC) associated with the UE 115 according to a detected trigger at the UE 115. For example, the UE 115 may receive a second control signaling indicating an uplink control channel group for the first CC or indicating an uplink control channel group configuration including an uplink control channel group for the first CC, and the detected trigger may be associated with receiving the second control signaling. In another example, the UE 115 may initiate a timer or a counter based on receiving a downlink transmission on the first CC, and may select an uplink control channel group for the first CC based on the expiration of the time or the value of the counter exceeding a threshold. In another example, the UE 115 may select an uplink control channel group for the first CC based on a scheduling type associated with the first CC. That is, the UE 115 may select a first uplink control channel group for the first CC based on the first CC being associated with a first scheduling type, and select a second uplink control channel group for the first CC based on the first CC being associated with a second scheduling type. Therefore, the UE 115 may send uplink control information for the first CC according to the selected uplink control channel group for the first CC.

[0088] Figure 2 An example of a wireless communication system 200 that supports dynamic uplink control channel grouping according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include one or more network entities 105 (e.g., network entity 105-a) and one or more UEs 115 (e.g., UE 115-a), which may be as described in reference Figure 1 Examples of corresponding devices described. Figure 2 In the example of FIG. 1 , the network entity 105 - a may be a CU 160, a DU 165, a RU 170, a base station 140, an IAB node 104, or a Figure 1 Examples of one or more other network nodes described. The wireless communication system 200 may include features for reducing latency and increasing reliability of uplink control information transmissions between the UE 115-a and the network entity 105-a, among other benefits.

[0089] In some examples, the wireless communication system may support carrier aggregation, which may increase (e.g., improve) the peak data rate of UE 115 (such as UE 115-a). That is, UE 115-a may communicate with network entity 105-a via multiple CCs 205 (e.g., according to carrier aggregation configuration), the multiple CCs including CC 205-a, CC 205-b, CC 205-c, and CC 205-d, wherein each CC 205 is associated with a set of frequency resources within one or more frequency bands (e.g., FR1, FR2). For example, CC 205-a may be associated with a first frequency band (e.g., FR1), and CC 205-b, CC 205-c, and CC 205-d may be associated with a second frequency band (e.g., FR2). Additionally, multiple CCs 205 may support multiple parameter sets (e.g., different parameter sets) associated with corresponding subcarrier spacings (SCSs). For example, CC 205-a may support a first SCS (e.g., associated with a first frequency band) that generates time slots 210-a (e.g., these time slots may be downlink time slots 225 or uplink time slots 220), and CC 205-b, CC 205-c and CC 205-d may support a second SCS (e.g., associated with a second frequency band) that generates time slots 210-b (e.g., these time slots may be downlink time slots 225 or uplink time slots 220).

[0090] In some cases, UE 115-a may support a first set of CCs 205 for uplink communication (e.g., UL-CCs 205) and a second set of CCs 205 for downlink communication (e.g., DL-CCs 205), wherein a first number of CCs 205 in the first set of CCs 205 is less than a second number of CCs 205 in the second set of CCs 205 (e.g., in a carrier aggregation configuration, DL-CCs 205 may be more than UL-CCs). Additionally or alternatively, UE 115-a may support self-scheduling of CCs 205 (e.g., self-carrier scheduling) and cross-carrier scheduling of CCs 205, as described in reference to Figure 3 described.

[0091] In some examples, UE 115-a may send uplink control information, such as feedback information (e.g., hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback) for downlink transmissions (e.g., physical downlink control channel (PDSCH)) received via multiple CCs 205. Additionally, UE 115-a may send uplink control information for downlink transmissions (e.g., a HARQ-ACK feedback process may be performed) based on one or more uplink control channel groups (e.g., physical uplink control channel (PUCCH) groups). That is, UE 115-a may receive control signaling (e.g., RRC signaling) indicating multiple uplink control channel groups 215 (e.g., up to two PUCCH groups) (e.g., may be configured with the multiple uplink control channel groups), where each uplink control channel group 215 may be associated with a different set of uplink control channel resources (e.g., PUCCH resources). For example, UE 115-a may be associated with (e.g., configured with) uplink control channel group 215-a and uplink control channel group 215-b. Additionally, uplink control channel group 215-a may be associated with a first set of uplink control channel resources associated with CC 205-a in uplink time slot 220, and uplink control channel group 215-b may be associated with a second set of uplink control channel resources associated with CC 205-d in uplink time slot 220.

[0092] Additionally, UE 115-a may support multiple uplink control channel group configurations. That is, CC 205 may belong to uplink control channel group 215-a according to uplink control channel group configuration 230-a, and may belong to uplink control channel group 215-b according to uplink control channel group configuration 230-b. For example, CC 205-a, CC 205-b, CC 205-c, and CC 205-d may belong to uplink control channel group 215-a according to uplink control channel group configuration 230-a. Additionally, according to uplink control channel group configuration 230-b, CC 205-a may belong to uplink control channel group 215-a, and CC 205-c, CC 205-c, and CC 205-d may belong to uplink control channel group 215-b.

[0093] In some examples, UE 115-a may operate (e.g., send uplink control information) according to uplink control channel group configuration 230-a (e.g., UE 115-a may not support uplink carrier aggregation for downlink carrier aggregation operation). In such cases, transmission of UCI (e.g., PUCCH, UCI) via CC 205-a may be associated with increased reliability compared to transmission of UCI via CC 205-b, CC 205-c, and CC 205-d. However, uplink transmissions (e.g., UL) on CC 205-a may support multiple (e.g., a large number) of bits (e.g., HARQ-ACK bits) associated with UCI for downlink transmissions (e.g., PDSCH) on each CC 205 in uplink control channel group 215-a (e.g., compared to uplink control channel group configuration 230-b). Additionally, the transmission of UCI (e.g., HARQ-ACK) associated with CC 205-b, CC 205-d, and CC 205-c may be delayed (e.g., compared to uplink control channel group configuration 230-b). That is, the first duty cycle of CC 205-a (e.g., in length) may be twice the second duty cycle of CC 205-b, CC 205-c, and CC 205-d, such that the transmission of UCI according to the duty cycle of CC 205-b may result in a delay in the transmission of UCI associated with CC 205-b, CC 205-d, and CC 205-c (e.g., compared to transmitting UCI according to the second duty cycle of CC 205-b, CC 205-c, and CC 205-d).

[0094] In some other examples, UE 115-a may operate (e.g., send uplink control information) according to uplink control channel group configuration 230-b (e.g., UE 115-a may support uplink carrier aggregation for downlink carrier aggregation operation). In such cases, transmission of UCI (e.g., PUCCH, UCI) via CC 205-b, CC 205-c, and CC 205-d may be associated with reduced reliability compared to transmission of UCI via CC 205-a. However, transmission of UCI (e.g., HARQ-ACK) associated with CC 205-b, CC 205-d, and CC 205-c (e.g., according to uplink control channel group configuration 230-b) may be associated with lower latency (e.g., compared to transmission of UCI associated with CC 205-b, CC 205-d, and CC 205-c according to uplink control channel group configuration 230-a). Additionally, transmission of UCI according to uplink control channel group configuration 230-b may support load balancing (eg, compared to uplink control channel group configuration 230-a).

[0095] Thus, each uplink control channel group configuration 230 may be suitable for reporting UCI for some scenarios (e.g., some types of data) but not for other scenarios (e.g., having different advantages and disadvantages). However, it may be beneficial to dynamically switch between uplink control channel group configurations (e.g., switch which CCs 205 belong to which uplink control channel group 215) (e.g., select these uplink control channel group configurations) in response to rapid changes in the type of data sent on each CCC 205.

[0096] Thus, the wireless communication system 200 may support dynamic uplink control channel grouping based on a detected trigger (e.g., a condition, an indication, or both) at the UE 115-a. For example, the network entity 105-a may send a first control signaling (e.g., RRC signaling) to the UE 115-a indicating multiple uplink control channel groups 215 (e.g., up to two uplink control channel groups 215), the multiple uplink control channel groups including an uplink control channel group 215-a associated with a first set of uplink control resources and an uplink control channel group 215-b associated with a second set of uplink control resources. Each uplink control channel group 215 may be associated with one or more uplink control channel group configurations 230 (such as an uplink control channel group configuration 230-a and an uplink control channel group configuration 230-b). In some cases, the first control signaling may include an indication of a plurality of uplink control channel group configurations 230 (eg, the network entity 105 - a may pre-configure the UE 115 - a with the plurality of uplink control channel group configurations 230 ).

[0097] UE 115-a may select an uplink control channel group 215 for CC 205 (such as CC 205-b) based on a detected trigger at UE 115-a. For example, UE 115-a may select uplink control channel group 215-a for CC 205-b based on a detected first trigger at UE 115-a, and may select uplink control channel group 215-b for CC 205-b based on a detected second trigger at UE 115-a.

[0098] In some examples, UE 115-a may receive second control signaling (e.g., a MAC control element (CE) carried by a PDSCH) indicating how each CC 205 is mapped to an uplink control channel group 215. That is, the detected trigger may be based on the second control signaling (e.g., reception of the second control signaling). For example, the second control signaling may indicate that CC 205-a belongs to (e.g., is mapped to) uplink control channel group 215-a, CC 205-b belongs to uplink control channel group 215-b, CC 205-c belongs to uplink control channel group 215-b, and CC 205-d belongs to uplink control channel group 215-b. In such a case, UE 115-a may apply (e.g., make effective) the indicated uplink control channel grouping (e.g., mapping) according to a time offset (e.g., 3ms). For example, the time offset may be based on sending feedback information associated with the second control signaling. That is, UE 115-a may send feedback information for a downlink shared channel (e.g., PDSCH) carrying second control information (e.g., MAC-CE), and may apply the indicated uplink control channel group after a duration (e.g., duration) associated with a time offset (e.g., a time offset after sending the feedback information).

[0099] Additionally or alternatively, UE 115-a may receive second control signaling indicating (e.g., configuring) a timer or counter, wherein the detected trigger is based on time or the counter. That is, UE 115-a may count the number of time slots (e.g., for the SCS) in an uplink control channel group 215 (such as uplink control channel group 215-a) in which UE 115-a did not receive a data transmission (e.g., PDSCH) on CC 205 such as CC 205-b or did not receive control signaling (e.g., a physical downlink control channel (PDCCH)) scheduling data transmission (e.g., PDSCH) on CC 205-b. UE 115-a may determine that CC 205-b belongs to uplink control channel group 215-a based on the number of time slots being less than or equal to a threshold number, and determine that CC 205-b belongs to uplink control channel group 215-b (e.g., preconfigured uplink control channel group 215) based on the number of time slots being greater than a threshold number.

[0100] In some examples, UE 115-a may count the number of time slots based on a timer. That is, UE 115-a may initiate a timer after receiving a data transmission (e.g., PDSCH) on CC 205-b in uplink control channel group 215-a or receiving control signaling (e.g., PDCCH) scheduling data transmission (e.g., PDSCH) on CC 205-b. In such a case, UE 115-a may send UCI for CC 205-b according to uplink control channel group 215-a while the timer is running (e.g., during the duration of the timer), and may send UCI for CC 205-b according to uplink control channel group 215-b after expiration of the timer (e.g., the number of time slots exceeds the configuration value of the timer).

[0101] In some other examples, UE 115-a may count the number of time slots based on a counter. That is, UE 115-a may initiate the counter after receiving a data transmission (e.g., PDSCH) on CC 205-b in uplink control channel group 215-a or receiving control signaling (e.g., PDCCH) that schedules data transmission (e.g., PDSCH) on CC 205-b. UE 115-a may increment the counter (e.g., by a value of 1) based on each time slot in uplink control channel group 215-a in which UE 115-a does not receive a data transmission on CC 205-b or does not receive control signaling that schedules data transmission on CC 205-b. In such a case, UE 115-a may send UCI for CC 205-b according to uplink control channel group 215-a based on the value of the counter (e.g., the number of time slots) being less than or equal to a threshold (e.g., indicated or configured via second control signaling), and may send UCI for CC 205-b according to uplink control channel group 215-b based on the value of the counter exceeding the threshold.

[0102] Additionally or alternatively, UE 115-a may receive second control signaling (e.g., downlink control information (DCI)) indicating an uplink control channel group configuration 230 (e.g., from a plurality of uplink control channel group configurations 230). That is, the indicated uplink control channel group configuration 230 may indicate how each CC 205 is mapped to an uplink control channel group 215. For example, UE 115-a may receive second control signaling indicating an uplink control channel group configuration 230-a, and may select an uplink control channel group 215-a for CC 205-a, CC 205-b, CC 205-c, and CC 205-d.

[0103] In some examples, UE 115-a may receive second control signaling indicating an index corresponding to an uplink control channel group configuration 230. That is, as previously described, network entity 105-a may send first control signaling indicating multiple uplink control channel group configurations 230, and each uplink control channel group configuration 230 may be associated with a corresponding index. Additionally, the detected trigger may be based on the second control signaling (e.g., reception of the second control signaling). Thus, the second control signaling may indicate an index, and UE 115-a may select an uplink control channel group 215 for each CC 205 based on the uplink control channel group configuration 230 corresponding to the indicated index. For example, uplink control channel group configuration 230-a may be associated with a first index, and uplink control channel group configuration 230-b may be associated with a second index. Additionally, the second control signaling may indicate a second index so that UE 115-a may select uplink control channel group 215-a for CC 205-a and uplink control channel group 215-b for CC205-b, CC 205-c and CC 205-d based on the second index corresponding to the uplink control channel group configuration 230-b.

[0104] In such cases, the UE 115-a may apply the indicated uplink control channel group configuration 230 (e.g., make it effective) based on a time offset (e.g., N time slots). For example, the time offset may be based on receiving a second control signaling, sending feedback information associated with the second control signaling, or both. That is, in some examples, the UE 115-a may receive a second control signaling (e.g., DCI) and may apply the indicated uplink control channel group configuration 230 after a duration (e.g., number of time slots) associated with the time offset (e.g., the time offset after receiving the second control signaling). Additionally or alternatively, the UE 115-a may send feedback information for the second control information (e.g., DCI) and may apply the indicated uplink control channel group configuration 230 after a duration associated with the time offset (e.g., the time offset after sending the feedback information).

[0105] In some cases, UE 115-a may send UCI for each CC 205 (e.g., perform a HARQ-ACK feedback process) based on the corresponding uplink control channel group 215. In some examples, UE 115-a may send UCI (e.g., HARQ-ACK) for each CC 205 (e.g., for the PDCCHs associated with each CC 205) in a selected uplink control channel group 215 (such as uplink control channel group 215-a) via a first set of resources (e.g., PUCCH) associated with the uplink control channel group 215-a. In such cases, the first set of resources may not overlap with a third set of resources associated with an uplink shared channel (e.g., a physical uplink shared channel (PUSCH)) further associated with the uplink control channel group 215-a. For example, UE 115-a may select uplink control channel group 215-a for CC 205-a, CC 205-b, CC 205-c, and CC 205-d. Additionally, a third set of resources associated with an uplink shared channel further associated with uplink control channel group 215-a may fall outside the first set of resources. Therefore, UE 115-a may send UCI (e.g., HARQ-ACK) for CC 205-a (e.g., PDSCH received via CC 205-a), for CC 205-b (e.g., PDSCH received via CC 205-b), for CC 205-c (e.g., PDSCH received via CC 205-c), and for CC 205-d (e.g., PDSCH received via CC 205-d) via the first set of resources.

[0106] Additionally or alternatively, UE 115-a may multiplex UCI for each CC 205 (e.g., for a PDS CHs associated with each CC 205) in a selected uplink control channel group 215 (such as uplink control channel group 215-a) on a fourth set of resources associated with an uplink shared channel (e.g., a fourth set of uplink shared channel resources) (e.g., performing a HARQ-ACK feedback process). In such a case, the first set of resources may at least partially overlap with the fourth set of resources. For example, UE 115-a may select an uplink control channel group 215-a for CC 205-a, CC 205-b, CC 205-c, and CC 205-d. Additionally, a fourth set of resources associated with an uplink shared channel further associated with uplink control channel group 215-a may overlap with the first set of resources. Thus, UE 115-a may multiplex UCI for CC 205-a, for CC 205-b, for CC 205-c, and for CC 205-d on a fourth set of resources. UE 115-a may send UCI associated with uplink control channel group 215 via a set of resources associated with uplink control channel group 215, or multiplex UCI associated with the uplink control channel group on a set of uplink shared channel resources associated with the uplink control channel group 215 independently between different uplink control channel groups 215 (e.g., the process for HARQ-ACK transmission using PUCCH or PUSCH is independent between different PUCCH groups).

[0107] Although much of the disclosure is described in the context of uplink control channel groups 215-a and uplink control channel groups 215-b, this should not be viewed as limiting the disclosure. In fact, it is contemplated herein that a UE 115 may support two uplink control channel groups 215. In this regard, any number of uplink control channel groups 215 may be contemplated with reference to the techniques described herein. Additionally or alternatively, any number of uplink control channel group configurations 230 and any number of CCs 205 may be contemplated with reference to the techniques described herein.

[0108] Figure 3 An example of a scheduling configuration 300 for supporting dynamic uplink control channel grouping according to one or more aspects of the present disclosure is illustrated. In some examples, the scheduling configuration 300 can implement aspects of the wireless communication system 100 and the wireless communication system 200. For example, the scheduling configuration 300 can be implemented by one or more network entities 105 and one or more UEs 115, which can be reference Figure 1Examples of corresponding devices described. Scheduling configuration 300 may include features for reducing latency and increasing reliability of uplink control information transmissions between UE 115 and network entity 105, among other benefits.

[0109] In some examples, UE 115 may communicate with network entity 105 via multiple CCs, including CC 305-a, CC 305-b, CC 305-c, and CC 305-d, wherein each CC 305 is associated with a set of frequency resources within one or more frequency bands (e.g., FR1, FR2). For example, CC 305-a may be associated with a first frequency band (e.g., FR1), and CC 305-b, CC 305-c, and CC 305-d may be associated with a second frequency band (e.g., FR2). Additionally, multiple CCs 305 may support multiple parameter sets (e.g., different parameter sets) associated with corresponding SCSs. For example, CC 305-a may support a first SCS (e.g., associated with a first frequency band) that generates time slots 310-a (e.g., these time slots may be downlink time slots 325 or uplink time slots 320), and CC 305-b, CC 305-c and CC 305-d may support a second SCS (e.g., associated with a second frequency band) that generates time slots 310-b (e.g., these time slots may be downlink time slots 325 or uplink time slots 320).

[0110] UE 115 may receive an indication of a plurality of uplink control channel groups 315 (including uplink control channel group 315-a and uplink control channel group 315-b), as shown in reference Figure 2 Additionally, UE 115 may select an uplink control channel group 315 for CC 305 based on a detected trigger at UE 115-a. In some examples, the detected trigger may be based on a scheduling type associated with CC 305, which may also be referred to as a scheduling configuration 300.

[0111] In some examples, a first CC 305 (such as CC 305-b) may be configured with multiple scheduling CCs 305. That is, the UE 115 may monitor a downlink control channel 330 (e.g., PDCCH) for CC 305-b on multiple scheduling CCs 305 simultaneously or on one CC 305 of the multiple CCs 305 at a time (e.g., not simultaneously). The downlink control channel 330 associated with CC 305-b may schedule one or more downlink data transmissions on CC 305-b.

[0112] In some examples, as depicted in scheduling configuration 300-a, UE 115 may monitor CC 305-a for a downlink control channel 330 associated with CC 305-a (e.g., scheduling downlink data transmission on CC 305-a), for a downlink control channel 330 associated with CC 305-b, for a downlink control channel 330 associated with CC 305-c, and for a downlink control channel 330 associated with CC 305-b. That is, CC 305-a may be associated with a first scheduling type, which may be referred to as single-cell scheduling (e.g., CC 305-a schedules the reception of downlink data sent on CC 305-a), and CC 305-b, CC 305-c, and CC 305-d may each be associated with a second scheduling type, which may be referred to as multi-cell scheduling or cross-carrier scheduling (e.g., CC 305-a schedules the reception of downlink data sent on CC 305-b, CC305-c, and CC 305-d).

[0113] In some examples, as depicted in scheduling configuration 300-b, UE 115 may monitor CC 305-a for a downlink control channel 330 associated with CC 305-a, may monitor CC 305-b for a downlink control channel 330 associated with CC 305-b, may monitor CC 305-c for a downlink control channel 330 associated with CC 305-c, and may monitor CC 305-d for a downlink control channel 330 associated with CC 305-b. That is, CC 305-a, CC 305-b, CC 305-c, and CC 305-d may each be associated with a first scheduling type.

[0114] Thus, UE 115 may select an uplink control channel group 315 for CC 305 (such as CC 305-b) based on whether CC 305-b is associated with the first scheduling type or the second scheduling type. That is, UE 115 may select an uplink control channel group 315 for CC 305-b based on UE 115 monitoring or detecting a downlink control channel 330 (e.g., PDSCH) of CC 305 that schedules downlink data transmission on CC 305-b.

[0115] For example, as depicted in scheduling configuration 300-a, UE 115 may monitor CC 305-a for downlink control channel 330 for downlink data transmission on scheduling CC 305-b. Therefore, CC 305-b may be associated with a second scheduling type (e.g., multi-cell scheduling). Therefore, UE 115 may select an uplink control channel group 315-a for CC 305-b based on monitoring CC 305-a for downlink control channel 330 for data transmission on scheduling CC 305-b. In other words, UE 115 may select an uplink control channel group 315-a for CC 305-b based on CC 305-b being associated with the second scheduling type (e.g., associated with scheduling configuration 300-a). Alternatively, as depicted in scheduling configuration 300-b, UE 115 may monitor CC 305-b for a downlink control channel 330 for downlink data transmission on scheduling CC 305-b. Therefore, CC 305-b may be associated with a first scheduling type (e.g., single cell scheduling). Therefore, UE 115 may select an uplink control channel group 315-b for CC 305-b based on monitoring CC 305-b for a downlink control channel 330 for downlink data transmission on scheduling CC 305-b. In other words, UE 115 may select an uplink control channel group 315-b for CC 305-b based on CC 305-b being associated with the first scheduling type (e.g., associated with scheduling configuration 300-b).

[0116] In some cases, the UE 115 may select the number of uplink control channel groups 315 to be used based on the first scheduling type or the second scheduling type. That is, the UE 115 may determine to use uplink control channel group 315-a and uplink control channel group 315-b based on monitoring multiple CCs 305 for corresponding downlink control channels 330 associated with multiple CCs 305 (e.g., single-cell scheduling), as depicted in scheduling configuration 300-b. Conversely, the UE 115 may determine to use uplink control channel group 315-a based on monitoring a single CC 305 (such as CC 305-a) for corresponding downlink control channels 330 associated with multiple CCs 305 (multi-cell scheduling), as depicted in scheduling configuration 300-b.

[0117] Figure 4An example of a process flow 400 for supporting dynamic uplink control channel grouping according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 400 can implement aspects of the wireless communication system 100, the wireless communication system 200, and the scheduling configuration 300. For example, the process flow 400 may include one or more network entities 105 (e.g., network entity 105-b) and one or more UEs 115 (e.g., UE 115-b), which may be as described in reference Figure 1 Examples of corresponding devices described. Figure 4 In the example of FIG. 1 , the network entity 105 - b may be a CU 160, a DU 165, a RU 170, a base station 140, an IAB node 104, or a Figure 1 Examples of one or more other network nodes are described. The process flow 400 may include features for reducing latency and increasing reliability of uplink control information transmissions between the UE 115-b and the network entity 105-b, among other benefits.

[0118] At 405, the network entity 105-b may send first control signaling to the UE 115-b indicating a plurality of uplink control channel groups for the UE 115-b, wherein each uplink control channel group in the plurality of uplink control channel groups is associated with a different set of uplink control channel resources. In some cases, the plurality of uplink control channel groups may be associated with a plurality of uplink control channel group configurations. For example, a CC may belong to a first uplink control channel group according to a first uplink control channel group configuration and may belong to a second uplink control channel group according to a second uplink control channel group configuration.

[0119] In some cases, at 410, the network entity 105-b may send second control signaling to the UE 115-b. In some examples, the second control signaling (e.g., MAC-CE) may indicate an uplink control channel group for a CC associated with the UE. Additionally or alternatively, the second control signaling (e.g., DCI) may indicate an uplink control channel group configuration from a plurality of uplink control channel group configurations (e.g., signaled via the first control signaling). In some examples, the second control signaling may include an index corresponding to an uplink control channel group configuration from a plurality of uplink control channel group configurations.

[0120] Additionally or alternatively, the second control signaling may indicate a timer or counter associated with multiple uplink control channel groups. In some cases, a first uplink control channel group may be associated with a duration of a timer or a value of a counter being less than or equal to a threshold, and a second uplink control channel group in the multiple uplink control channel groups may be associated with an expiration of a timer or a value of a counter being greater than a threshold. Additionally, the time or counter may be associated with a first number of time slots in which UE 115-b did not receive data transmission on a CC in a first uplink control channel group in the multiple uplink control channel groups or a second number of time slots in which UE 115-b did not receive a third control message scheduling data transmission on the CC.

[0121] At 415, UE 115-b may select an uplink control channel group for a CC associated with UE 115-b, and the uplink control channel group may be selected based on a detected trigger at UE 115-b. In some cases, the detected trigger may be associated with (e.g., based on) the second control signaling. That is, UE 115-b may select the uplink control channel group for the CC based on the uplink control channel group or uplink control channel group configuration indicated in the second control signaling.

[0122] Additionally or alternatively, the detected trigger may be associated with the expiration of a timer or the value of a counter. That is, as previously described, UE 115-b may select a first uplink control channel group for the CC before the expiration of the timer (e.g., during the duration of the timer) or before the value of the counter exceeds a threshold (e.g., is less than a threshold), and may select a second uplink control channel group for the CC after the expiration of the timer or after the value of the counter exceeds the threshold.

[0123] Additionally or alternatively, the detected trigger may be associated with a scheduling type associated with the CC such that UE 115-b may select an uplink control channel group for the CC based on the scheduling type associated with the CC. For example, a first uplink control channel group among a plurality of uplink control channel groups may be associated with a first scheduling type, and a second uplink control channel group among a plurality of uplink control channel groups may be associated with a second scheduling type. In some cases, the first scheduling type may correspond to at least one of multi-cell scheduling or cross-carrier scheduling, and the second scheduling type may correspond to single-cell scheduling.

[0124] In some cases, UE 115-b may apply (e.g., select and apply) an uplink control channel group for a CC based on a time offset (e.g., a time delay), and the time offset may be based on sending feedback associated with a second control signaling or based on receiving the second control signaling. For example, UE 115-b may receive a second control signaling (e.g., indicating an uplink control channel group configuration), and may apply an uplink control channel group for a CC (e.g., activate the uplink control channel group, make the uplink control channel group valid) at a time offset (e.g., N time slots) after receiving the second control signaling. In another example, UE 115-b may send feedback information (e.g., ACK) for a second control signaling (e.g., DCI), and may apply an uplink control channel group for a CC at a time offset (e.g., N time slots) after sending the feedback information for the second control signaling. In another example, UE 115-b may send feedback information for a downlink shared channel (e.g., PDSCH) associated with a second control signaling (e.g., MAC-CE), and may apply an uplink control channel group for the CC at a time offset (e.g., 3 ms) after sending the feedback information for the downlink shared channel (e.g., starting from the timing when UE 115-b sends an ACK).

[0125] In some examples, UE 115-b may select a second uplink control channel group for a second CC associated with UE 115-b, and the second uplink control channel group may be selected based on a detected trigger at UE 115-b. In some cases, the uplink control channel group for the CC may be the same as the second uplink control channel group for the second CC. Alternatively, the uplink control channel group for the CC may be different from the second uplink control channel group for the second CC.

[0126] In some cases, at 420, the UE may multiplex uplink control information for the CCs on a set of uplink shared channel resources, and the set of uplink shared channel resources may at least partially overlap with a set of uplink control channel resources associated with the selected uplink control channel group.

[0127] At 425, UE 115-b may send uplink control information for the CC based on the selected uplink control channel group. In some examples, UE 115-b may send uplink control information for the CC using a set of uplink control channel resources associated with the selected uplink control channel group. In some other examples, UE 115-b may send the multiplexed uplink control information for the CC on a set of uplink shared channel resources.

[0128] In some examples, UE 115-b may send second uplink control information for a second component carrier based on the selected second uplink control channel group.

[0129] Figure 5 A block diagram 500 of a device 505 supporting dynamic uplink control channel grouping according to one or more aspects of the present disclosure is shown. The device 505 may be an example of aspects of the UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. The device 505 or one or more components of the device 505 (e.g., the receiver 510, the transmitter 515, and the communication manager 520) may also include one or more processors, a memory coupled to the one or more processors, and instructions stored in the memory that can be executed by the one or more processors to enable the one or more processors to perform the features discussed herein. Each of these components may communicate with each other (e.g., via one or more buses).

[0130] Receiver 510 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to dynamic uplink control channel packets).
