Technical Field

The following relates to wireless communications, including techniques for dynamically applying repetition factors for beams.

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 able to support 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 various 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 or one or more network access nodes, each of which simultaneously support communication for multiple communication devices, which may be otherwise referred to as User Equipment (UE).

SUMMARY

The described technology relates to improved methods, systems, devices, and apparatus supporting techniques for dynamically applying repetition factors for beams. In general, the described techniques provide for dynamically indicating repetition factors for uplink control signaling. A User Equipment (UE) may be configured to transmit repetitions of an uplink control channel message, such that the repetitions are transmitted using a plurality of uplink control channel resources. The UE may receive first control signaling that configures a first repetition factor associated with a feedback message (e.g., for scheduled downlink data transmissions). The UE may be configured to repeatedly apply the uplink control channel to other uplink control messages associated with the same beam or Transmission Configuration Indicator (TCI) status as the feedback message. For example, the UE may receive second control signaling that schedules the UE for another uplink control message, such as a periodic Channel State Information (CSI) report or feedback for a periodic shared channel transmission. The UE may apply a second repetition factor to transmit the other uplink control message based on the first uplink repetition factor and a second control signaling that schedules the uplink control message.

Detailed Description

A User Equipment (UE) in a wireless communication system may be configured to transmit repetitions of an uplink control channel message. For example, the UE may be configured to perform Physical Uplink Control Channel (PUCCH) repetition and transmit each repetition of uplink control information using multiple PUCCH resources in different slots. Implementing PUCCH repetition may increase reliability of uplink transmission from the UE. The UE may be configured with a repetition factor and the UE may transmit the uplink control message according to the repetition factor (e.g., transmit several repetitions corresponding to the repetition factor). In some cases, the UE may be configured with a repetition factor per PUCCH resource set. The resources for repetition may be dynamically indicated via PUCCH Resource Indication (PRI) in the downlink control information of the scheduled downlink shared channel transmission. However, such a configuration may correspond only to PUCCH carrying feedback for scheduled downlink shared channel transmissions, and not to other uplink control messages.

Techniques to dynamically indicate repetition factors that may be applied to multiple uplink control messages are described. For example, an access network entity (which may include a base station or may be an example of a base station) may indicate to a UE a dynamic repetition factor for PUCCH transmissions carrying feedback for a scheduled Physical Downlink Shared Channel (PDSCH), and the UE may apply PUCCH repetition to other uplink control messages associated with the same Transmission Configuration Indicator (TCI) state based on the dynamic repetition factor. Other uplink control messages may include, for example, uplink control messages for semi-periodic scheduling (SPS) resources or uplink control messages for Channel State Information (CSI) measurements. The UE may also apply PUCCH repetition to an uplink control message providing feedback for SPS downlink shared channel transmission if the uplink control message providing feedback for SPS downlink shared channel transmission is associated with the same TCI state as an uplink control message providing feedback for scheduled downlink shared channel transmission (which is configured for PUCCH repetition).

The dynamic repetition factor may be indicated to the UE explicitly or implicitly. For example, the access network entity may use a PRI bit field or another bit field in DCI scheduling a downlink shared channel to indicate the dynamic repetition factor. In some cases, the dynamic repetition factor may be implicitly indicated by a configuration of a downlink control channel (such as an aggregation level for the downlink control channel, or a location of a control channel element in the downlink control channel) that schedules downlink shared channel transmissions. In some cases, the UE may determine a second repetition factor to apply to other uplink control messages based on the dynamic repetition factor. For example, the UE may apply a repetition factor of 2 for an uplink control message providing feedback for scheduled downlink shared channel transmissions, and the UE may apply a repetition factor of 4 for an uplink control message associated with periodic CSI. In some cases, the second repetition factor may be included with or configured using second control signaling that configures the uplink control message. Some additional techniques for implementing dynamic PUCCH repetition are described herein.

Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to techniques for dynamically applying repetition factors for beams.

Fig. 1 illustrates an example of a wireless communication system 100 supporting techniques for dynamically applying repetition factors for beams 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 different forms of devices or devices with different capabilities. The base station 105 and the UE 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 and ues 115 and base stations 105 may establish one or more communication links 125 over the coverage area 110. Coverage area 110 may be an example of a geographic area over which base station 105 and UE 115 may support signal communications in accordance with one or more radio access technologies.

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. Each UE 115 may be a different form of device or a device with different capabilities. Some example UEs 115 are illustrated in fig. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, 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.

Each base station 105 may communicate with the core network 130, or with each other, or both. For example, the base station 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or both directly and indirectly over the backhaul link 120 (e.g., via an X2, xn, or other interface). In some examples, the backhaul link 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 those of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a node B, an evolved node B (eNB), a next generation node B or a giganode B (any of which may be referred to as a gNB), a home node B, a home evolved node B, or other suitable terminology.

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 "device" may also be referred to as a unit, station, terminal, client, or the like. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular telephone, a Personal Digital Assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a Wireless Local Loop (WLL) station, an internet of things (IoT) device, a 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.

The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base stations 105 and network equipment including macro enbs or gnbs, small cell enbs or gnbs, relay base stations, etc., as shown in fig. 1.

The UE 115 and the base station 105 may wirelessly communicate with each other over one or more carriers via one or more communication links 125. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, the carrier for the communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of the radio frequency spectrum band that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE-A, LTE-a Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with UEs 115 using carrier aggregation or multi-carrier operation. The 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 Frequency Division Duplex (FDD) and Time Division Duplex (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 the operation of other carriers. The carrier may be associated with a frequency channel, such as an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN), and may be positioned according to a channel grid for discovery by the UE 115. The carrier may operate in a standalone mode, in which initial acquisition and connection may be made by the UE 115 via the carrier, or the carrier may operate in a non-standalone mode, in which connections are anchored using different carriers (e.g., different carriers of the same or different radio access technologies).

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

The 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 the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication over a particular carrier bandwidth or may be configurable to support communication over one carrier bandwidth in a set of carrier bandwidths. In some examples, wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over part (e.g., sub-band, BWP) or all of the carrier bandwidth.

The signal waveform transmitted on the carrier may include a plurality of subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as Orthogonal Frequency Division Multiplexing (OFDM) or discrete fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, the resource elements may include one symbol period (e.g., 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 code rate of the modulation scheme, or both). Thus, the more resource elements that the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate of the UE 115 may be. The wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of the communication with the UE 115.

One or more parameter designs for the carrier may be supported, where the parameter designs may include a subcarrier spacing (Δf) and a cyclic prefix. The carrier may be divided into one or more BWP with the same or different parameter designs. In some examples, UE 115 may be configured with multiple BWP. In some examples, a single BWP for a carrier may be active at a given time, and communications for UE 115 may be limited to one or more active BWPs.

The time interval of the base station 105 or the UE 115 may be expressed in multiples of a basic time unit, which may refer to, for example, a sampling period T _s ＝1/(Δf _max ·N _f ) Second, Δf _max Can represent the maximum supported subcarrier spacing, and N _f The maximum supported Discrete Fourier Transform (DFT) size may be represented. The 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).

Each frame may include a plurality of consecutively numbered subframes or slots, and each subframe or 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 dividedDivided into a number of time slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. Excluding cyclic prefix, each symbol period may contain one or more (e.g., N _f A number) of sampling periods. The duration of the symbol period may depend on the subcarrier spacing or the operating frequency band.

A subframe, slot, mini-slot, or symbol may be a minimum 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 the 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 (sTTI)).

The physical channels may be multiplexed on the carrier according to various techniques. The physical control channels and physical data channels may be multiplexed on the downlink carrier, for example, using one or more of Time Division Multiplexing (TDM) techniques, frequency Division Multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. The control region (e.g., control resource set (CORESET)) for the physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., core) may be configured for the set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more sets of search spaces, and each set of search spaces may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level for control channel candidates may refer to the 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. The set of search spaces may include a common set of search spaces configured to transmit control information to a plurality of UEs 115 and a set of UE-specific search spaces configured to transmit control information to a particular UE 115.

Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity for communicating with a base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., a Physical Cell Identifier (PCID), a Virtual Cell Identifier (VCID), or otherwise) for distinguishing between neighboring cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of geographic coverage area 110 over which a logical communication entity operates. Such cells may range from a smaller area (e.g., structure, subset of structures) to a larger area 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 buildings, or an external space between geographic coverage areas 110 or overlapping geographic coverage areas 110, among other examples.

The macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 115 with service subscription with network providers supporting the macro cell. The small cell may be associated with a lower power base station 105 (as compared to the macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. The small cell may provide unrestricted access to UEs 115 with service subscription with the network provider or may provide restricted access to UEs 115 with association with the small cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also support communication over the one or more cells using one or more 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, the base station 105 may be mobile and thus provide communication coverage to the mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, 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 base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

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

Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to a data communication technology that allows devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communications or MTC may include communications from devices integrated with sensors or meters to measure or capture information and relay such information to a central server or application that utilizes or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or to implement automated behavior of a machine or other device. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based business charging.

Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communications may be performed with reduced peak rates. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged 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 associated with a defined portion or range (e.g., a subcarrier or set of Resource Blocks (RBs)) within, within a guard band of, or outside of a carrier.

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 communications (URLLC) or mission critical communications. The UE 115 may be designed to support ultra-reliable, low latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communications or group communications, 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 prioritizing services, and mission critical services may be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

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

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

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 (5 GC), which may include at least one control plane entity (e.g., a Mobility Management Entity (MME), an access and mobility management function (AMF)) that manages 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)) that routes packets or interconnects to an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be communicated through a user plane entity that may provide IP address assignment, as well as other functions. The user plane entity may be connected to IP services 150 of one or more network operators. The IP service 150 may include access to the internet, an intranet, an IP Multimedia Subsystem (IMS), or a packet switched streaming service.

Some network devices, such as base station 105, may include subcomponents, such as access network entity 140, which may be an example of an Access Node Controller (ANC). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, intelligent radio heads, or transmission/reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the 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 incorporated into a single network device (e.g., 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, a region of 300MHz to 3GHz is called a Ultra High Frequency (UHF) region or a decimeter band because the wavelength ranges from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by building and environmental features, but these waves may penetrate various structures for macro cells sufficiently to serve UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) than transmission of smaller and longer waves using High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz.

The wireless communication system 100 may also operate in an ultra-high frequency (SHF) region using a frequency band from 3GHz to 30GHz (also referred to as a centimeter frequency band) or in an extremely-high frequency (EHF) region of a frequency spectrum (e.g., from 30GHz to 300 GHz) (also referred to as a millimeter frequency band). In some examples, wireless communication system 100 may support millimeter wave (mmW) communication between UE 115 and base station 105, and EHF antennas of respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may experience even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary from country to country or regulatory agency to regulatory agency.

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

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

Base station 105 or UE 115 may utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers using MIMO communication. Such techniques may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Likewise, the receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the plurality of 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 a different data stream (e.g., a different codeword). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiver device; and multi-user MIMO (MU-MIMO), wherein the plurality of spatial layers are transmitted to the plurality of 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., base station 105, UE 115) to shape or steer antenna beams (e.g., transmit beams, receive beams) along a spatial path between the transmitting device and the receiving device. Beamforming may be implemented by combining signals communicated via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signal communicated via the antenna element may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both, to the signal carried via the antenna element associated with the device. The adjustment associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., with respect to an antenna array of a transmitting device or a receiving device, or with respect to some other orientation).

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

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

In some examples, the transmission by the device (e.g., by the base station 105 or the 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 the base station 105 to the UE 115). The UE 115 may report feedback indicating 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 subbands. The base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRSs), CSI reference signals (CSI-RS)) that may be precoded or not precoded. 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 by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a recipient device).

The receiving device (e.g., UE 115) may attempt multiple reception configurations (e.g., directed listening) upon receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105. For example, the recipient device may attempt multiple directions of reception by: the received signals are received via different antenna sub-arrays, processed according to different antenna sub-arrays, received according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or processed according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the recipient device may use a single receive configuration to receive in a single beam direction (e.g., when receiving the data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other 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. At the user plane, the communication of the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. The 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 multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission by the MAC layer to improve link efficiency. In the control plane, a Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or the core network 130 supporting radio bearers of user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UE 115 and the base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is properly received over the communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward Error Correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

The wireless communication system 100 may support techniques for PUCCH repetition. The UE 115 in the wireless communication system 100 may be configured to transmit repetitions of an uplink control channel message (e.g., PUCCH) message using multiple PUCCH resources in different slots. For example, UE 115 may receive DCI scheduling PDSCH data transmissions and PUCCH transmissions carrying feedback for the PDSCH data transmissions. UE 115 may be configured to apply PUCCH repetition to PUCCH transmissions and the DCI may indicate a plurality of PUCCH resources for each repetition (e.g., according to a PRI field in the DCI). Implementing PUCCH repetition may provide coverage enhancement for UE 115. In some cases, PUCCH repetition may be implemented for demodulation reference signal (DMRS) bundling across PUCCH repetition.

The UE may be configured with a repetition factor and the UE may transmit an uplink control message according to the repetition factor (e.g., transmit a number of repetitions corresponding to the repetition factor). In some cases, UE 115 may be configured with a repetition factor per PUCCH resource set. In some examples, UE 115 may receive a dynamic indication of PRI via DCI scheduling PDSCH. However, such a configuration may be applied only to PUCCHs that carry feedback (e.g., acknowledgement (ACK) or Negative ACK (NACK)) feedback for scheduled PDSCH. Thus, such a configuration may not enable PUCCH repetition for other types of uplink control messages.

The wireless communication system 100 may implement techniques for dynamically indicating repetition factors that may be applied to different uplink control messages (e.g., different types of uplink control messages). For example, PUCCH repetition factors indicated for PUCCHs carrying ACKs for scheduled PDSCH may be applied to other PUCCHs associated with the same TCI state. The PUCCH repetition factor (e.g., dynamic PUCCH repetition factor) may be indicated to UE 115 explicitly or implicitly. For example, the base station 105 may indicate the dynamic repetition factor using a PRI bit field or another bit field in the scheduling DCI for the PDSCH. In some cases, the dynamic repetition factor may be implicitly indicated by the PDCCH scheduling the PDSCH. For example, the aggregation level or the location of CCEs in the PDCCH may implicitly indicate a dynamic repetition factor.

In some cases, dynamic repetition may be applied to other PUCCH messages until the configuration is updated. For example, the UE 115 may apply PUCCH repetition for other uplink transmissions when PUCCH and other PUCCH transmissions for the scheduled PDSCH are associated with the same TCI state, or when other PUCCH transmissions have an active configuration. In some cases, the UE may apply PUCCH repetition to other PUCCH transmissions based on the configuration of the PUCCH resource set indicated by the PRI in the scheduling DCI. In some examples, dynamic repetition may be applied to other PUCCH transmissions based on a frequency range or subcarrier spacing of resources used to transmit the other PUCCH transmissions.

Fig. 2 illustrates an example of a wireless communication system 200 supporting techniques for dynamically applying repetition factors for beams in accordance with aspects of the disclosure. The wireless communication system 200 may be an example of the wireless communication system 100 or aspects of the wireless communication system 100 may be implemented. The wireless communication system 200 may include a UE 115-a and a base station 105-a, which may be respective examples of the UE 115 and the base station 105 as described with reference to fig. 2. In some examples, the base station 105-a may be an example of an access network entity.

UE 115-a and base station 105-a may support beamformed communications. For example, the UE 115-a may communicate with the base station 105-a using the beam 205 and the base station 105-a may communicate with the UE 115-a using the beam 210. The beam 210 used to communicate with the UE 115-a may be associated with a TCI state. In some cases, different beams at base station 105-a may be associated with different Synchronization Signal Blocks (SSBs) and different TCI states. If the UE 115-a moves or changes location, the base station 105-a may update the TCI state of the UE 115-a to a different beam pointing to the new location of the UE 115-a.

UE 115-a may support PUCCH repetition. For example, UE 115-a may be configured to transmit multiple repetitions of an uplink control channel message, which may increase the reliability of uplink signaling or decoding success at base station 105-a. The UE 115-a may be configured with a repetition factor and the UE 115-a may transmit the uplink control message according to the repetition factor (e.g., by transmitting a number of repetitions of the uplink control message corresponding to the repetition factor).

In an example, the UE 115-a may receive first control signaling 215 indicating a first repetition factor for transmission of feedback messages associated with the beam. For example, the first control signaling 215 may include DCI that schedules data transmissions (e.g., PDSCH transmissions) of the UE 115-a. The DCI may also schedule uplink resources for feedback messages for data transmission. The first control signaling 215 may indicate a first repetition factor and uplink resources for transmitting repetitions 225 of the feedback message.

In some cases, the base station 105-a may explicitly or implicitly indicate the first repetition factor to the UE 115-a. For example, the dynamic repetition factor or the first repetition factor may be indicated by a PRI bit field or another bit field in DCI of the scheduled PDSCH. The UE 115-a may decode the DCI scheduling the PDSCH and determine the first repetition factor from a field in the DCI. In some cases, the first repetition factor may be explicitly indicated by a field in the DCI, or may be implicitly indicated. For example, the PRI may indicate a plurality of uplink resources for uplink feedback, and the UE 115-a may determine the first repetition factor from the plurality of uplink resources by implicit indication. In some other examples, the field may explicitly indicate a value of the first repetition factor or an entry of a repetition factor table configured at the UE 115-a.

In some cases, the dynamic repetition factor may be indicated based on a configuration of PDCCH resources carrying DCI scheduling PDSCH. For example, the first repetition factor may be implicitly indicated based on an aggregation level of the PDCCH. Additionally or alternatively, the first repetition factor may be indicated based on the location of CCEs in the PDCCH. For example, a particular configuration of PDCCH or a particular CCE location may indicate a first repetition factor to UE 115-a and indicate repetition 225 for UE 115-a to transmit a feedback message according to the first repetition factor.

UE 115-a may apply PUCCH repetition for other uplink messages based on the first repetition factor and control signaling for the other uplink messages. For example, UE 115-a may apply PUCCH repetition to an uplink control message carrying feedback for SPS PDSCH, an uplink control message associated with periodic CSI, an uplink control message associated with semi-persistent CSI, an uplink control message associated with a scheduling request, or any combination thereof, as well as other types of uplink control messages. In some cases, UE 115-a may apply PUCCH repetition to other uplink messages based on the other uplink messages being associated with the same TCI state (e.g., the same beam) as the feedback message transmitted in repetition 225. For example, the base station 105-a may use the same TCI state for the uplink message transmitted in repetition 225 and the uplink message transmitted in repetition 230.

In an example, UE 115-a may receive second control signaling 220 that schedules transmission of control messages associated with the beam. UE 115-a may determine repetition 230 to apply PUCCH repetition to transmit the control message based on the control message and the feedback message being associated with the same beam or the same TCI state. Additionally or alternatively, UE 115-a may apply PUCCH repetition to transmit repetition 230 based on the scheduled PDSCH transmission and SPS PDSCH or periodic CSI associated with the same TCI state. For example, the base station 105-a may transmit the scheduled PDSCH and the SPS PDSCH using the same TCI state, and the UE 115-a may apply PUCCH repetition to transmit feedback for both the scheduled PDSCH and the SPS PDSCH.

In some cases, UE 115-a may transmit repetition 225 according to a first repetition factor and may transmit repetition 230 according to a second repetition factor. In some cases, the second repetition factor may be different from the first repetition factor. For example, UE 115-a may transmit two repetitions of the feedback message in repetition 225 and UE 115-a may transmit four repetitions of the uplink control message in repetition 230. In some cases, the UE 115-a may determine the second repetition factor based on control signaling for other uplink control messages.

For example, repetition 230 may include repetition of an uplink control message for SPS PDSCH. The base station 105-a may configure the SPS PDSCH via control signaling (such as RRC signaling) to schedule half-period PDSCH resources for the UE 115-a. In some cases, the configuration for SPS PDSCH resources may include an indication of a second repetition factor. UE 115-a may determine that: the SPS PDSCH is associated with the same TCI state as the scheduled PDSCH, or the feedback message for the SPS PDSCH is associated with the same TCI state as the feedback for the scheduled PDSCH, or both, and it is determined that PUCCH repetition is to be applied to the feedback message for the SPS PDSCH. The UE 115-a may determine a second repetition factor based on the first repetition factor or the configuration for the SPS PDSCH or both and transmit a repetition 230 of an uplink control message associated with the SPS PDSCH to the base station 105-a in accordance with the second repetition factor.

In some additional or alternative examples, repetition 230 may include repetition of an uplink control message for periodic CSI (such as CSI reporting) on the PUCCH. The base station 105-a may configure the periodic CSI via control signaling (such as RRC signaling) to schedule the UE 115-a for periodic CSI measurements. In some cases, the configuration for periodic CSI may include an indication of a second repetition factor. UE 115-a may determine that: the periodic CSI is associated with the same TCI state as the scheduled PDSCH, or the uplink control message for the periodic CSI is associated with the same TCI state as the feedback for the scheduled PDSCH, or both, and it is determined that PUCCH repetition is to be applied to the uplink control message associated with the periodic CSI. The UE 115-a may determine a second repetition factor based on the first repetition factor or the configuration for periodic CSI or both and transmit a repetition 230 of an uplink control message associated with periodic CSI to the base station 105-a according to the second repetition factor.

In some cases, the second repetition factor may be the same as the first repetition factor. For example, the first repetition factor may be indicated to the UE 115-a, and the UE 115-a may apply the first repetition factor to both the feedback message (e.g., to transmit repetition 225) and other uplink control messages (e.g., to transmit repetition 230). In some cases, control signaling for other uplink control messages may indicate that the same repetition factor as the feedback message is to be used.

In some examples, the second control signaling 220 (e.g., for other control messages) may indicate uplink resources for the repetition 230. For example, the base station 105-a may configure several PUCCH resources for transmitting repetition via the second control signaling 220. In some cases, UE 115-a may determine a second repetition factor based on the configured uplink resources for repetition 230. Additionally or alternatively, the UE 115-a may determine resources for repetition 230 based on the first control signaling 215 of the scheduled PDSCH transmission. In some cases, UE 115-a may apply PUCCH repetition for uplink control messages (e.g., other uplink control messages) according to rules for applying dynamic repetition to other PUCCH transmission(s) using the same beam or having the same TCI state (e.g., dynamic repetition rules are always applied to other PUCCHs specified in the wireless standard).

In some cases, UE 115-a may apply PUCCH repetition for uplink control messages (e.g., other uplink control messages) within a configured time interval. For example, the second control signaling 220 may indicate a duration for which PUCCH repetition is applied to the uplink control message after PUCCH repetition is activated. UE 115-a may receive first control signaling 215 indicating that PUCCH repetition is to be used for feedback messages, which may trigger or activate PUCCH repetition for other uplink control message(s). UE 115-a may apply a second repetition factor to the other uplink control message(s) for a duration after PUCCH repetition is triggered or activated. For example, the timer may span several occasions for SPS PDSCH feedback or periodic CSI uplink control messages, and UE 115-a may transmit uplink control messages for SPS PDSCH or periodic CSI according to a corresponding repetition factor when the timer is active. When the timer is stopped or running ends, the UE 115-a may refrain from applying the corresponding repetition factor to the uplink control message until PUCCH repetition is triggered or activated again.

Additionally or alternatively, UE 115-a may apply PUCCH repetition to uplink control message(s) (e.g., other uplink control messages) until UE 115-a receives an updated configuration message or is instructed to cease using PUCCH repetition for uplink control message(s). For example, the base station 105-a may transmit first control signaling 215, which may trigger or activate PUCCH repetition for other uplink control messages. UE 115-a may apply PUCCH repetition to other uplink control messages until base station 105-a sends signaling to disable or deactivate PUCCH repetition for other uplink control messages. In some cases, the signaling to switch (e.g., activate or deactivate, enable or disable) PUCCH repetition for other uplink control messages may be sent using RRC signaling, MAC CE, downlink control information, or any combination thereof. For example, the base station 105-a may transmit DCI signaling that schedules the second PDSCH transmission, and the DCI signaling that schedules the second PDSCH transmission may not include an indication of PUCCH repetition. The UE 115-a may refrain from applying PUCCH repetition to other uplink control signaling based on receiving DCI signaling to schedule the second PDSCH transmission.

In some cases, UE 115-a may determine whether to apply PUCCH repetition to the uplink control message based on the configuration for the uplink control message. For example, UE 115-a may be configured with two SPS PDSCH configurations. The first SPS PDSCH configuration may be configured to support PUCCH repetition and the second SPS PDSCH configuration may be configured to not support PUCCH repetition. The UE 115-a may apply PUCCH repetition for the uplink control message associated with the first SPS PDSCH configuration and may not apply PUCCH repetition for the uplink control message associated with the second SPS PDSCH configuration. In some cases, PUCCH resources configured for the second SPS PDSCH configuration may not support PUCCH repetition. In some cases, UE 115-a may determine not to apply PUCCH repetition for some uplink control messages. In an example, the first SPS PDSCH configuration may be associated with a higher priority than the second SPS PDSCH configuration, and thus UE 115-a may refrain from applying PUCCH repetition to uplink control messages associated with the second SPS PDSCH configuration, which may provide more resources for uplink control messages associated with the first SPS PDSCH configuration.

In some cases, the UE 115-a may determine whether to apply PUCCH repetition based on the first control signaling 215 (e.g., including DCI scheduling PDSCH transmissions), such as based on a PUCCH resource set indicated by the PRI in the first control signaling 215. If the uplink control message is not configured to support PUCCH repetition (such as based on the set of PUCCH resources indicated by the first control signaling 215), then the UE 115-a may not apply PUCCH repetition to the uplink control message.

In some cases, UE 115-a may apply PUCCH repetition to the uplink control message based on a frequency range, a frequency band, a subcarrier spacing (SCS), or any combination thereof associated with the uplink control message. For example, UE 115-a may apply PUCCH repetition in some frequency ranges and not apply PUCCH repetition in other frequency ranges. For example, UE 115-a may apply PUCCH repetition only to uplink control messages transmitted in frequency range 2 (FR 2), and UE 115-a may not apply PUCCH repetition to uplink control messages transmitted in frequency range 1 (FR 1). Additionally or alternatively, UE 115-a may apply PUCCH repetition for uplink control messages configured for a certain SCS and not apply PUCCH repetition for uplink control messages configured for other SCS. For example, UE 115-a may apply PUCCH repetition to an uplink control message at SCS of 30KHz or above, and may not apply PUCCH repetition to an uplink control message at SCS below 30 KHz. In some cases, UE 115-a may receive one or more configurations indicating one or more SCS, one or more aggregation levels, one or more control channel elements, one or more frequency bands, one or more frequency ranges, or any combination thereof for which PUCCH repetition is to be applied or not applied. For example, base station 105-a may indicate that FR2 supports PUCCH repetition.

In some cases, UE 115-a may apply PUCCH repetition based on a PUCCH format or an uplink control information size. For example, if the uplink control message has a configured format or a specific uplink control information size, the UE 115-a may apply PUCCH repetition to transmit repetition 230 of the uplink control message. In some cases, UE 115-a may receive control signaling indicating that PUCCH repetition is to be applied for a particular format or a particular uplink control information size. For example, UE 115-a may apply PUCCH repetition for uplink control messages at a particular size (e.g., a particular bit size), and UE 115-a may not apply PUCCH repetition for longer uplink control messages (e.g., above a particular bit size).

The UE 115-a may transmit a repetition 230 of the uplink control message to the base station 105-a according to the second repetition factor. Transmitting repetition 230 according to the second repetition factor may promote reliability for uplink control messages. As described herein, the UE 115-a may implement these techniques for a variety of different types of uplink control messages. For example, UE 115-a may implement these techniques for uplink control messages associated with SPS PDSCH and uplink control messages associated with periodic CSI. In some cases, UE 115-a may transmit the repetition of the uplink control message for the SPS PDSCH and the repetition of the uplink control message for the periodic CSI separately according to different repetition factors in some cases. The repetition of the uplink control message for the SPS PDSCH and the repetition of the uplink control message for the periodic CSI may have separate uplink resources for transmitting the repetition (e.g., such that the repetition does not overlap).

The base station 105-a may receive a repetition 230 of the uplink control message. In some cases, the base station 105-a may perform soft combining on the repetition 230 to obtain the uplink control message. This may increase reliability for transmission of uplink control messages.

Fig. 3 illustrates an example of a process flow 300 supporting techniques for dynamically applying repetition factors for beams in accordance with aspects of the disclosure. The process flow 300 may be implemented by the UE 115-b or the base station 105-b, or both, which may be respective examples of the UE 115 and the base station 105 described with reference to fig. 1 and 2. Process flow 300 may implement aspects of wireless communication system 100 or 200. Some of the operations or signaling of process flow 300 may be implemented in a different order than shown by fig. 3. Additionally, some operations or signaling may be removed, or some operations or signaling may be added.

At 305, the base station 105-b may transmit first control signaling indicating a first repetition factor for transmission of feedback messages associated with the beam. UE 115-b may receive the first control signaling message. In some cases, the first control signaling may include DCI scheduling PDSCH transmissions to UE 115-b. The DCI may indicate (e.g., explicitly or implicitly) the first repetition factor, the second repetition factor, or both to the UE 115-b.

At 310, the base station 105-b may transmit second control signaling that schedules transmission of control messages associated with the beam (e.g., from the UE 115-b). In some cases, the second control signaling may be, for example, an SPS PDSCH configuration or a periodic CSI configuration configured at the UE 115-b. In some cases, the second control signaling may at least partially configure a second repetition factor associated with the control message.

In some cases, ue 115-b may determine a second repetition factor associated with the control message at 315. For example, UE 115-b may determine the second repetition factor based on the first repetition factor or the second control signaling, or both. In some cases, UE 115-b may determine to enable or activate PUCCH repetition for the control message based on the first control signaling indicating the first repetition factor. The UE 115-b may determine a second repetition factor based on the second control signaling. For example, the SPS PDSCH configuration or the periodic CSI configuration at the UE 115-b may include a corresponding repetition factor.

In some cases, UE 115-b may determine to apply PUCCH repetition when transmitting a control message based on the feedback message and the control message being associated with the same beam or TCI state. For example, the feedback message may provide feedback for PDSCH transmissions. In some cases, the control message may be associated with another downlink signal (such as SPS PDSCH transmission or periodic CSI). In some cases, the UE 115-b may determine to apply PUCCH repetition to the control message based on PDSCH transmissions and other downlink signals associated with the same TCI state. Additionally or alternatively, the UE 115-b may determine to apply PUCCH repetition to the control message based on the feedback message and the control message being associated with the same TCI state.

At 320, ue 115-b may transmit the control message according to a second repetition factor based on the feedback message and the control message being associated with the beam. For example, the control message may include feedback for SPS PDSCH transmissions, and the UE 115-b may transmit multiple repetitions of the feedback for SPS PDSCH transmissions according to a second repetition factor. In some cases, the control message may include a periodic CSI report, and the UE 115-b may transmit multiple repetitions of the periodic CSI report according to a second repetition factor.

The base station 105-b may receive the control message according to a second repetition factor based on both the feedback message and the control message being associated with the beam. In some cases, the base station 105-b may soft combine repetitions of the control message to decode the control message.

This may provide increased reliability of uplink transmissions from the UE.
