A user equipment (UE) may identify a default transmission configuration indicator (TCI) state for reception of one or more repetitions of a downlink control transmission over a corresponding one or more control resource sets. The UE may identify one or more reference signal transmissions that are time bundled with respect to the one or more repetitions of the downlink control transmission. The UE may identify a TCI state associated with the one or more reference signal transmissions, the TCI state being different than the default TCI state. The UE may receive, based at least in part on the time bundled one or more reference signal transmissions, the one or more repetitions of the downlink control transmission, a downlink data transmission, or a combination thereof, according to the TCI state associated with the one or more reference signal transmissions.

Description

TRANSMISSION CONFIGURATION INDICATOR STATE DETERMINATION VIA CONTROL CHANNEL REPETITION AND TIME BUNDLED REFERENCE SIGNALS

FIELD OF TECHNOLOGY

The following relates generally to wireless communications and more specifically to transmission configuration indicator state determination via control channel repetition and time bundled reference signals.

BACKGROUND

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the 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, LTE-Advanced (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 technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal frequency division multiple access (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE) .

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support transmission configuration indicator (TCI) state determination via control channel repetition and time bundled reference signals. Generally, the described techniques provide various proposals that support physical downlink control channel (PDCCH) and/or physical downlink shared channel (PDSCH) TCI state determination based on time domain (TD) , bundled, or more simply time bundled, reference signals (such a demodulation reference signal (DMRS) transmissions) . For example, a default TCI state may generally be configured (e.g., the default TCI state may be the TCI state associated with a synchronization signal block (SSB) configuration provided by to the UE by the base station) . Accordingly, the UE and/or base station may know the default TCI state configuration. However, the UE and/or base station may identify or otherwise determine that the repetitions of a downlink control transmission (e.g., PDCCH repetition transmissions) do not have a corresponding activated or otherwise known TCI state. For example, the UE and/or base station may identify or otherwise determine that a control resource set (CORESET) for the PDCCH repetitions have not been indicated by a medium access control (MAC) control element (CE) as activated for the PDCCH repetitions and that a TCI present in a downlink control information (DCI) indicator (e.g., a tci-PresentInDCI indicator) has not been received. Accordingly, the base station and/or UE may identify a TCI state associated with reference signal transmissions (e.g., DMRS transmissions) and select or otherwise use the TCI state of the reference signal transmissions as the TCI state for receiving the PDCCH repetitions and/or PDSCH repetitions. Accordingly, the quasi-colocation (QCL) relationship associated with the PDCCH/PDSCH repetitions may be improved, e.g., the QCL information associated with the DMRS transmissions may be more accurate than the QCL information in the default TCI state.

A method of wireless communication at a UE is described.

DETAILED DESCRIPTION

Wireless communication systems may operate in millimeter wave (mmW) frequency ranges, e.g., 28 GHz, 40 GHz, 60 GHz, etc. Wireless communications at these frequencies may be associated with increased signal attenuation (e.g., path loss) , which may be influenced by various factors, such as temperature, barometric pressure, diffraction, etc. As a result, signal processing techniques, such as beamforming, may be used to coherently combine energy and overcome the path losses at these frequencies. Due to the increased amount of path loss in mmW communication systems, transmissions from the base station and/or the user equipment (UE) may be beamformed. Moreover, a receiving device may use beamforming techniques to configure antenna (s) and/or antenna array (s) such that transmissions are received in a directional manner.

Such beamforming techniques may include a transmission configuration indicator (TCI) state being configured for, or otherwise associated with, beamformed communications. Broadly, the TCI state may define the quasi-colocation (QCL) relationship associated with beamformed communications. Antenna ports may be considered quasi co-located if the properties of the channel for one antenna port that a symbol is transmitted can be inferred from the channel for another antenna port that a symbol is transmitted. Examples of the channel properties that can be used may include, but are not limited to, Doppler shift, Doppler spread, average delay, delay spread, spatial receive parameters, and the like. Each TCI state may generally include parameters for configuring the QCL relationship between downlink reference signals (e.g., channel state information (CSI) reference signals and demodulation reference signals (DMRSs) associated with a transmission. Accordingly, an accurately configured TCI state (e.g., a TCI state that addresses the correct channel properties) may improve such beamformed communications between devices. However, in some situations the wireless devices may be configured to adopt a default TCI state rather than a TCI state properly matched to the channel properties. This may disrupt communications over the channel.

Aspects of the disclosure are initially described in the context of wireless communication systems. Generally, the described techniques provide various proposals that support physical downlink control channel (PDCCH) and/or physical downlink shared channel (PDSCH) TCI state determination based on time domain (TD) bundled reference signals (such demodulation reference signal (DMRS) transmissions) . For example, a default TCI state may generally be configured (e.g., the default TCI state may be the TCI state associated with a synchronization signal block (SSB) configuration provided to the UE by the base station) . Accordingly, the UE and/or base station may know the default TCI state configuration. However, the UE and/or base station may identify or otherwise determine that the repetitions of a downlink control transmission (e.g., PDCCH repetition transmissions) do not have a corresponding activated or otherwise known TCI state. For example, the UE and/or base station may identify or otherwise determine that a control resource set (CORESET) for the PDCCH repetitions have not been indicated by a medium access control (MAC) control element (CE) as activated for the PDCCH repetitions and that a TCI present in a downlink control information (DCI) indicator (e.g., a tci-PresentInDCI indicator) has not been received. Accordingly, the base station and/or UE may identify a TCI state associated with reference signal transmissions (e.g., DMRS transmissions) and select or otherwise use the TCI state of the reference signal transmissions as the TCI state for receiving the PDCCH repetitions and/or PDSCH repetitions. Accordingly, the quasi-colocation (QCL) relationship associated with the PDCCH/PDSCH repetitions may be improved, e.g., the QCL information associated with the DMRS transmissions may be more accurate than the QCL information in the default TCI state.

Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to TCI state determination via control channel repetition and time bundled reference signals.

FIG. 1 illustrates an example of a wireless communication system 100 that supports TCI state determination via control channel repetition and time bundled reference signals in accordance with aspects of the present disclosure. The wireless communication system 100 may include one or more base stations 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 LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices in different forms or having different capabilities. The base stations 105 and the UEs 115 may wirelessly communicate via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support the communication of signals according to one or more radio access technologies.

The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, the base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) , as shown in FIG. 1.

The base stations 105 may communicate with the core network 130, or with one another, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface) . The base stations 105 may communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 105) , or indirectly (e.g., via core network 130) , or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

One or more of the base stations 105 described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or other suitable terminology.

A 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 terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A 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, a UE 115 may include or 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 communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the base stations 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

The UEs 115 and the base stations 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) ) that is operated 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 that coordinates operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

In some examples (e.g., in a carrier aggregation configuration) , a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN) ) and may be positioned according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .

The communication links 125 shown in the wireless communication system 100 may include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .

A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communication system 100 (e.g., the base stations 105, the UEs 115, or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105 or UEs 115 that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

Signal waveforms transmitted over a carrier may be made up of 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 consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are 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) . Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams) , and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.

One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. 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 the UE 115 may be restricted to one or more active BWPs.

The time intervals for the base stations 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T _s=1/ (Δf _max·N _f) seconds, where Δf _max may represent the maximum supported subcarrier spacing, and N _f may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource 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) .

Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communication systems 100, a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N _f) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

A subframe, a slot, a mini-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 bursts of shortened TTIs (sTTIs) ) .

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

Each base station 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a base station 105 (e.g., over a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with geographic coverage areas 110, among other examples.

A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered base station 105, as compared with a macro cell, and a small cell may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A base station 105 may support one or multiple cells and may also support communications over the one or more cells using one or multiple component carriers.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.

In some examples, a base station 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timings, and transmissions from different base stations 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.

Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that makes use of the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception simultaneously) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating over a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.

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

In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol) . One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1: M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a base station 105.

In some systems, the D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications, or with both.

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 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to the network operators IP services 150. The operators IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.

Some of the network devices, such as a base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC) . Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs) . Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105) .

The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

The wireless communication system 100 may also operate in a super high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UEs 115 and the base stations 105, and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate use of antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.

The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA) . Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

A base station 105 or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within 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 a base station 105 may be located in diverse geographic locations. A base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.

The base stations 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , where multiple spatial layers are transmitted to multiple devices.

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 base station 105, a UE 115) to shape or steer 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 the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .

A base station 105 or a UE 115 may use beam sweeping techniques as part of beam forming operations. For example, a base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station 105 multiple times in different directions. For example, the base station 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the base station 105.

Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.

In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device) .

A receiving device (e.g., a UE 115) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .

The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UEs 115 and the base stations 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link 125. 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 in poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

A UE 115 may identify a default TCI state for reception of one or more repetitions of a downlink control transmission over a corresponding one or more control resource sets. The UE 115 may identify one or more reference signal transmissions that are time bundled with respect to the one or more repetitions of the downlink control transmission. The UE 115 may identify a TCI state associated with the one or more reference signal transmissions, the TCI state being different than the default TCI state. The UE 115 may receive, based at least in part on the time bundled one or more reference signal transmissions, the one or more repetitions of the downlink control transmission, a downlink data transmission, or a combination thereof, according to the TCI state associated with the one or more reference signal transmissions.

A base station 105 may transmit, to a UE 115, an indication of a default TCI state for the UE 115 to receive one or more repetitions of a downlink control transmission over a corresponding one or more control resource sets. The base station 105 may transmit one or more reference signal transmissions that are time bundled with respect to the one or more repetitions of the downlink control transmission, the one or more reference signal transmissions associated with a TCI state that is different from the default TCI state. The base station 105 may transmit, based at least in part on the time bundled one or more reference signal transmissions, the one or more repetitions of the downlink control transmission, a downlink data transmission, or a combination thereof, according to the TCI state associated with the one or more reference signal transmissions.

FIG. 2 illustrates an example of a transmission configuration 200 that supports TCI state determination via control channel repetition and time bundled reference signals in accordance with aspects of the present disclosure. In some examples, transmission configuration 200 may implement aspects of wireless communication system 100. Aspects of transmission configuration 200 may be implemented by a base station and/or UE, which may be examples of the corresponding devices described herein.

In some wireless communication systems, a UE may be associated with a UE type with a limited or reduced bandwidth, low complexity level, low transmit maximum power level, a reduced number of antennas, an extended battery life, etc. Such UE type may include wearable devices, IoT devices, MTC devices, and the like. To compensate for coverage loss in the downlink, wireless communication systems may support PDCCH/PDSCH (or simply PDxCH) repetitions. That is, two or more repetitions of a PDxCH signal may be repeated to improve reliability and robustness of the signal transmission. In some aspects, using PDxCH repetition may, at least to some degree, compensate for the UE having fewer receive antennas.

Wireless communication system 100 may also support TD DMRS bundling. TD bundling of DMRS over the PDxCH repetitions may improve repetition performance. However, TD DMRS bundling (e.g., DMRS that are not otherwise associated with the PDxCH transmission) provides additional improvements in compensating for the reduced number of receive antennas. Frequency hopping may also be combined with TD DMRS bundling to provide further performance improvements. For example, two hops over four repetitions with TD DMRS bundling may perform as well as, or better than, four hops over four repetitions.

As discussed above, TCI states may be activated for a PDxCH transmission to define the QCL relationship between signals. For example, the TCI state of a PDSCH transmission may be determined by different techniques. In a first technique, the offset between the reception of a downlink DCI and the corresponding PDSCH may be greater than, or equal to, the time threshold “timeDurationForQCL. ” For this first technique, if a “tci-PresentInDCI” indicator is enabled for the CORESET with respect to the DCI scheduling the PDSCH, the UE may use the TCI field in the DCI to determine the TCI state of the PDSCH. When the UE is configured with a multi-slot PDSCH, the indicated TCI state may be based on the activated TCI states in the first slot with the scheduled PDSCH, and the UE may determine that the activated TCI states are the same across the slots with the scheduled PDSCH. If the “tci-PresentInDCI” indicator is not configured for the CORESET with respect to the DCI scheduling the PDSCH, the UE may determine that the TCI state for the PDSCH is identical to (e.g., the same as) the TCI state for the CORESET used for the PDCCH transmission.

In a second technique, the offset between the reception of the downlink DCI and the corresponding PDSCH may be less than the time threshold timeDurationForQCL. For this second technique, the UE may determine that the DMRS ports of a PDSCH of a serving cell are QCL’d with the reference signal (s) with respect to the QCL parameter (s) used for the PDCCH QCL indication of the CORESET associated with a monitored search space with the lowest “controlResourceSetId” in the latest slot in which one or more CORESETs within the active bandwidth part (BWP) of the serving cell are monitored by the UE.

In some aspects, each CORESET may be configured with a list of TCI state candidates (e.g., in a “tci-StatesPDCCH-ToAddList” indicator) . A MAC CE may be used to indicate one of the configured TCI states for a certain CORESET, e.g., using a MAC CE message. When the CORESETs for PDCCH repetitions have not been indicated (e.g., by a MAC-CE) as activated for their TCI-states and the “tci-PresentInDCI” indicator is not configured for these CORESETs, the default QCL (e.g., default TCI state) may be adopted for such PDCCH repetitions (and/or the PDSCH repetitions scheduled by the DCI) . However, such default QCL (e.g., the default TCI state) may not provide the best performance (e.g., may not be the most suited TCI state for the current channel conditions) . If additional TD bundled DMRS are configured for the PDCCH repetitions, this may help identify a better QCL/TCI state such that the performance of the PDxCH repetitions can be improved.

Accordingly, aspects of the described techniques may provide techniques to determine the TCI state of the PDCCH/PDSCH repetitions scheduled by PDCCH repetitions with TD DMRS bundling. Transmission configuration 200 illustrates an example where the PDCCH TCI state may be determined using additional DMRS (e.g., DMRS 245) . In some aspects, the offset between reception of the downlink DCI and the corresponding PDSCH may be greater than, or equal to the time threshold timeDurationForQCL. There may not have been any TCI state that has been MAC CE activated for the CORESETS in the PDCCH repetitions. The additional DMRS (e.g., DMRS 245) may be TD bundled with one or more of the PDCCH repetitions, and the additional DMRS may be identified by another CORESET comprising a TCI-state that was activated by a MAC-CE command (e.g., CORESET 250) , or by another PDSCH with a known TCI-state (e.g., PDSCH 255) . The TCI state of the CORESETs in the PDCCH repetitions may be the same as the TCI state identified by the additionally TD bundled DMRS.

That is, the UE may configured, or otherwise scheduled with CORESET 205 associated with PDCCH repetition 225, CORESET 210 associated with PDCCH repetition 230, CORESET 215 associated with PDCCH repetition 235, and CORESET 220 associated with PDCCH repetition 240. However, the UE may determine or otherwise identify that CORESETS 205-220 do not have an activated TCI state (e.g., have not been MAC CE activated) . Accordingly, the UE may identify a default TCI state for reception of PDCCH repetitions 225-240 (e.g., one or more repetitions of a downlink control transmission) . For example, the UE may have previously received a radio resource control (RRC) signal configuring the default TCI state. The UE may also identify or otherwise determine that one or more reference signal transmissions (e.g., DMRS 245) are time bundled (e.g., TD) with respect to the PDCCH repetitions 225-240.

The UE may identify the TCI state associated with the one or more reference signal transmissions (e.g., DMRS 245) . For example, the TCI state of DMRS 245 may be based on a MAC CE activated TCI state for CORESET 250. In some aspects, this may include the UE receiving a MAC CE indicating information associated with CORESET 250 associated with DMRS 245. As is illustrated in transmission configuration 200, CORESET 250 is different than CORESETS associated with the PDxCH repetitions (e.g., CORESETS 205-220 associated with PDCCH repetitions 225-240, respectively) . In some aspects, the MAC CE may carry or otherwise convey an indication of information identifying the TCI state of DMRS 245.

As another example, the TCI state of DMRS 245 may be a known TCI state associated with PDSCH 255 (e.g., the TCI state for a previous data transmission scheduled by a DCI indicating the TCI state) . For example, this may include identifying a previous data transmission (e.g., PDSCH 255) indicating, or otherwise associated with, DMRS 245. This may include the UE receiving a DCI from a base station scheduling PDSCH 255 and indicating the TCI state for PDSCH 255.

The UE may identify or otherwise adopt the TCI state of DMRS 245 or PDSCH 255 as the TCI state for receiving the PDCCH repetitions 225-240. The UE may receive the one or more repetitions of the PDxCH (e.g., PDCCH repetitions 225-240) according to the TCI state of DMRS 245.

FIG. 3 illustrates an example of a transmission configuration 300 that supports TCI state determination via control channel repetition and time bundled reference signals in accordance with aspects of the present disclosure. In some examples, transmission configuration 300 may implement aspects of wireless communication system 100 and/or transmission configuration 200. Aspects of transmission configuration 300 may be implemented by a base station and/or UE, which may be examples of the corresponding devices described herein.

Aspects of the described techniques may provide techniques to determine the TCI state of the PDCCH/PDSCH repetitions scheduled by PDCCH repetitions with TD DMRS bundling. Transmission configuration 300 illustrates an example where the PDSCH TCI state may be determined using additional DMRS (e.g., DMRS 345) . In some aspects, the offset between reception of the downlink DCI and the corresponding PDSCH may be greater than, or equal to the time threshold timeDurationForQCL. There may not have been any TCI state that has been MAC CE activated for the CORESETS in the PDCCH repetitions. The additional DMRS (e.g., DMRS 345) may be TD bundled with one or more of the PDCCH repetitions. The additional DMRS may be identified by another CORESET comprising a TCI-state that was activated by a MAC-CE command (e.g., CORESET 350) , or by another PDSCH with a known TCI-state (e.g., PDSCH 355) . The TCI state of the CORESETs in the PDCCH repetitions may be the same as the TCI state identified by the additionally TD bundled DMRS.

That is, the UE may configured, or otherwise scheduled with CORESET 305 associated with PDCCH repetition 325, CORESET 310 associated with PDCCH repetition 330, CORESET 315 associated with PDCCH repetition 335, and CORESET 320 associated with PDCCH repetition 340. However, the UE may determine or otherwise identify that CORESETS 305-320 do not have an activated TCI state (e.g., have not been MAC CE activated) . Accordingly, the UE may identify a default TCI state for reception of PDCCH repetitions 325-340 (e.g., one or more repetitions of a downlink control transmission) . For example, the UE may have previously received a radio resource control (RRC) signal configuring the default TCI state. The UE may also identify or otherwise determine that one or more reference signal transmissions (e.g., DMRS 345) are time bundled (e.g., TD) with respect to the PDCCH repetitions 325-340.

The UE may identify the TCI state associated with the one or more reference signal transmissions (e.g., DMRS 345) . For example, the TCI state of DMRS 345 may be based on a MAC CE activated TCI state for CORESET 350. In some aspects, this may include the UE receiving a MAC CE indicating information associated with CORESET 350 associated with DMRS 345. As is illustrated in transmission configuration 300, CORESET 350 is different than CORESETS associated with the PDxCH repetitions (e.g., CORESETS 305-320 associated with PDCCH repetitions 325-340, respectively) . In some aspects, the MAC CE may carry or otherwise convey an indication of information identifying the TCI state of DMRS 345. In some examples, the UE may identify the TCI state associated with the one or more reference signal transmissions (e.g., DMRS 345) based on an enabled tci-PresentInDCI indicator. For example, the TCI state of DMRS 345 may be based on a received DCI comprising a TCI state indicator field indicating the TCI state associated with CORESET 350/DMRS 345.

As another example, the TCI state of DMRS 345 may be a known TCI state associated with PDSCH 355 (e.g., the TCI state for a previous data transmission scheduled by a DCI indicating the TCI state) . For example, this may include identifying a previous data transmission (e.g., PDSCH 355) indicating, or otherwise associated with, DMRS 345. This may include the UE receiving a DCI from a base station scheduling PDSCH 355 and indicating the TCI state for PDSCH 355.

The UE may identify or otherwise adopt the TCI state of DMRS 345 or PDSCH 355 as the TCI state for receiving the PDCCH repetitions 325-340. The UE may receive the one or more repetitions of the PDxCH (e.g., PDCCH repetitions 325-340) according to the TCI state of DMRS 345.

FIG. 4 illustrates an example of a transmission configuration 400 that supports TCI state determination via control channel repetition and time bundled reference signals in accordance with aspects of the present disclosure. In some examples, transmission configuration 400 may implement aspects of wireless communication system 100 and/or transmission configurations 200 and/or 300. Aspects of transmission configuration 400 may be implemented by a base station and/or UE, which may be examples of the corresponding devices described herein.

Aspects of the described techniques may provide techniques to determine the TCI state of the PDCCH/PDSCH repetitions scheduled by PDCCH repetitions with TD DMRS bundling. Transmission configuration 400 illustrates an example where the multiple PDSCH TCI states may be determined using additional DMRSs (e.g., DMRS 415 and DRMS 430) . In some aspects, the offset between reception of the downlink DCI and the corresponding PDSCH may be greater than, or equal to the time threshold timeDurationForQCL. A first set of PDCCH repetitions (e.g., PDCCH repetition 405 and PDCCH repetition 410) may be TD bundled with a first set of reference signal transmissions (e.g., DMRS 415) and a second set PDCCH repetitions (e.g., PDCCH repetition 420 and PDCCH repetition 425) may be TD bundled with a second set of reference signal transmissions (e.g., DMRS 430) . There may not have been any TCI state that has been MAC CE activated for the CORESETS in the PDCCH repetitions. Each of the additional DMRS may be identified by another CORESET comprising a TCI-state that was activated by a MAC-CE command or by another PDSCH with a known TCI-state. The first set of PDCCH repetitions (e.g., PDCCH repetition 405 and PDCCH repetition 410) that are TD bundled with the first set of reference signal transmissions (e.g., DMRS 415) may be associated with a first slot that is different than a second slot of the second set of PDCCH repetitions (e.g., PDCCH repetition 420 and PDCCH repetition 425) that are TD bundled with the second set of reference signal transmissions (e.g., DMRS 430) . Moreover, the first set of reference signal transmissions (e.g., DMRS 415) that are TD bundled with the first set of PDCCH repetitions (e.g., PDCCH repetition 405 and PDCCH repetition 410) may be associated with a first TCI state that is different than a second TCI state of the second set of reference signal transmissions (e.g., DMRS 430) that are TD bundled with the second set of PDCCH repetitions (e.g., PDCCH repetition 420 and PDCCH repetition 425) . The TCI state of the CORESETs in the first set of PDCCH repetitions may be the same as the TCI state identified by the additionally TD bundled DMRS 415 and the TCI state of the CORESETs in the second set of PDCCH repetitions may be the same as the TCI state identified by the additionally TD bundled DMRS 430.

That is, the UE may configured, or otherwise scheduled with a first CORESET associated with PDCCH repetition 405, a second CORESET associated with PDCCH repetition 410, a third CORESET associated with PDCCH repetition 420, and a fourth CORESET associated with PDCCH repetition 425. However, the UE may determine or otherwise identify that the CORESETS do not have an activated TCI state (e.g., have not been MAC CE activated and/or activated by a tci-PresentInDCI indicator) . Accordingly, the UE may identify a default TCI state for reception of

PDCCH repetitions

405, 410, 420, and 425 (e.g., one or more repetitions of a downlink control transmission) . For example, the UE may have previously received a RRC signal configuring the default TCI state. The UE may also identify or otherwise determine that the first set of reference signal transmissions (e.g., DMRS 415) are time bundled with respect to the

PDCCH repetitions

405 and 410. The UE may also identify or otherwise determine that the second set of reference signal transmissions (e.g., DMRS 430) are time bundled with respect to the

PDCCH repetitions

420 and 425.

The UE may identify the TCI states associated with the first and second sets of reference signal transmissions (e.g., DMRS 415 and 430) .

In a first example, the first TCI state of DMRS 415 and the second TCI state of DMRS 430 may not be configured via a tci-PresentInDCI field indicator, but may have been activated by respective MAC CE messages. Accordingly, the UE may receive one or more MAC CE messages that indicate the first TCI state of DMRS 415 and the second TCI state of DMRS 430.

In another example, the first TCI state of DMRS 415 or the second TCI state of DMRS 430 may not have been MAC CE activated, but may have been configured via the tci-PresentInDCI field indicator. In this example, the TCI state indicated in the DCI may be used or otherwise adopted as the first TCI state for the first set of PDCCH repetitions (e.g., PDCCH repetitions 405 and 410) and as the second TCI state for the second set of PDCCH repetitions (e.g., PDCCH repetitions 420 and 425) . Accordingly, the UE may receive a DCI for one or more previous data transmissions (e.g., PDSCH (s) associated with DMRS 415 and/or DMRS 430) that indicate the first TCI state of DMRS 415 and the second TCI state of DMRS 430.

In another example, the first TCI state of DMRS 415 may not be configured via a tci-PresentInDCI field indicator, but may have been activated by a MAC CE message. In this example, the first TCI state may be adopted for the

PDCCH repetitions

405 and 410 based at least in part on the MAC CE message indicating the first TCI state. In this example, the second TCI state of DMRS 430 may not be MAC CE activated, but may be associated with a previous data transmission. That is, the second TCI state of DMRS 430 may be adopted for the

PDCCH repetitions

420 and 425 based at least in part on the UE receiving a DCI scheduling the previous data transmission (e.g., PDSCH) that indicates the second TCI state.

In another example, the first TCI state of DMRS 415 and the second TCI state of DMRS 430 may not be MAC CE activated, but may be configured via a tci-PresentInDCI field indicator. Accordingly, the UE may receive one or more DCI messages that indicate the first TCI state of DMRS 415 and the second TCI state of DMRS 430.

In another example, the first TCI state of DMRS 415 and the second TCI state of DMRS 430 may be configured based at least in part on one or more previous data transmission (s) . Accordingly, the UE may receive one or more DCI messages scheduling the previous data transmissions that indicate the first TCI state of DMRS 415 and the second TCI state of DMRS 430. The one or more previous data transmission may be associated with DMRS 415 and/or 430.

The UE may identify or otherwise adopt the first TCI state of DMRS 415 as the TCI state for receiving the

PDCCH repetitions

405 and 410 and the second TCI state of DMRS 430 as the TCI state for receiving the

PDCCH repetitions

420 and 425. The UE may receive the one or more repetitions of the PDxCH (e.g.,

PDCCH repetitions

405, 410, 420, and 425) according to the adopted TCI states of

DMRS

415 and 430.

FIG. 5 illustrates an example of a process 500 that supports TCI state determination via control channel repetition and time bundled reference signals in accordance with aspects of the present disclosure. In some examples, process 500 may implement aspects of wireless communication system 100 and/or

transmission configurations

200, 300, and/or 400. Aspects of process 500 may be implemented by UE 505 and/or base station 510, which may be examples of the corresponding devices described herein.

At 515, base station 510 may transmit (and UE 505 may receive) an indication of a default TCI state for UE 505 to receive one or more repetitions of the downlink control transmission (e.g., PDCCH) over corresponding one or more CORESETs. In some aspects, the default TCI state may transmitted in an upper layer message, such as an RRC message. In some aspects, the default TCI state may be based on one or more SSBs configured by base station 510. That is, base station 510 configuring the SSBs for UE 505 may convey the indication of the default TCI state.

At 520, UE 505 may identify the default TCI state, e.g., based on the RRC message received from base station 510. In some aspects, the default TCI state may be a TCI state that UE 505 is otherwise configured to adopt when receiving a downlink transmission from base station 510 that is not otherwise configured with an activated TCI state.

At 525, base station 510 may transmit (and UE 505 may receive) one or more reference signal transmissions (e.g., DMRS (s) ) that are TD bundled with respect to the one or more repetitions of the downlink control transmission. These reference signal transmissions may be different than the default TCI state.

At 530, UE 505 may determine or otherwise identify the one or more reference signal transmissions that are TD bundled with the one or more repetitions of the downlink control transmission and, at 535 UE 505 may determine or otherwise identify the TCI state associated with the one or more reference signal transmission.

In some aspects, this may include base station 510 transmitting (and UE 505 receiving) a MAC CE that carries or otherwise conveys an indication of a CORESET associated with the one or more reference signal transmissions. In some aspects, this CORESET may be different from the CORESET (s) corresponding to the one or more repetitions of the downlink control transmissions.

In some aspects, this may include base station 510 transmitting (and UE 505 receiving) a previous data transmission (e.g., PDSCH) indicating or otherwise associated with the one or more reference signal transmissions. In some aspects, the previous data transmission may carry or otherwise convey an indication of the TCI state of the one or more reference signal transmissions. Accordingly, UE 505 may identify the TCI state of the one or more reference signal transmissions based at least in part on the previous data transmission.

In some aspects, this may include base station 510 transmitting (and UE 505 receiving) a DCI for the previous data transmission associated with the one or more reference signal transmissions. The DCI may carry or otherwise convey an indication of the TCI state associated with the one or more reference signal transmissions. UE 505 may identify the TCI state associated with the one or more reference signal transmissions based on the DCI.

In some aspects, this may include base station 510 transmitting (and UE 505 receiving) a first set of reference signal transmissions that are TD bundled with respect to a first set of repetitions of the downlink control transmission. Base station 510 may also transmit (and UE 505 may receive) a second set of reference signal transmissions that are TD bundled with respect to a second set of repetitions of the downlink control transmission. UE 505 may identify a first TCI state associated with the first set of reference signal transmissions and a second TCI state associated with the second set of reference signal transmissions. In some aspects, the first and/or second TCI states associated with the corresponding first and second sets of reference signal transmissions may be different from the default TCI state.

In some aspects, a MAC CE message transmitted from base station 510 may indicate a control resource set associated with the first set of reference signal transmissions and/or the second set of reference signal transmissions. The MAC CE message may carry or otherwise convey an indication of the first TCI state associated with the first set of reference signal transmissions and/or the second TCI state associated with the second set of reference signal transmissions.

In some aspects, base station 510 may transmit (and UE 505 may receive) a previous data transmission carrying or otherwise conveying an indication of the first set of reference signal transmissions and/or second set of reference signal transmissions. In some aspects, this may include base station 510 transmitting a DCI scheduling the previous data transmission, with the DCI carrying or otherwise conveying an indication of the first TCI state and/or the second TCI state.

Accordingly and at 540, base station 510 may transmit (and UE 505 may receive) the one or more repetitions of the downlink control transmission and/or downlink data transmission (e.g., PDxCH repetition transmissions) according to the TCI state associated with the one or more reference signal transmissions. In some aspects, this may include base station 510 transmitting (and UE 505 may receiving) the first set of repetitions of the downlink transmission (e.g., PDxCH) according to the first TCI state and a second set of repetitions of the downlink transmission (e.g., PDxCH) according to the second TCI state. In some aspects, the first set of repetitions of the downlink transmission (e.g., PDxCH) may be received in a first slot according to the first TCI state while the second set of repetitions of the downlink transmission (e.g., PDxCH) may be received in a second slot according to the second TCI state.
