Demodulation reference signal bundling and frequency hopping

Abstract

Methods, systems, and devices are described for wireless communication to support phase continuity in bundled uplink transmissions within a bundling interval. In a first example, a user equipment (UE) can determine a bundling interval for uplink channel transmissions based on a transmission time interval (TTI) format pattern and a bundling size. The bundling interval can start at a next available uplink TTI after an end of a previous bundling interval, such that each bundling interval can include at least one uplink TTI. In a second example, the UE can use frequency resources for repetitions of uplink channel transmissions within a bundling interval based on an index of the bundling interval. In a third example, the UE can not bundle certain repetitions of uplink channel transmissions in a same bundling interval and can use different frequency resources for the repetitions based on one or more phase continuity rules.

Technical Field

[0003] The following discussion pertains to wireless communications, including demodulation reference signal (DMRS) bundling and frequency hopping. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-A, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended 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 supports communication for multiple communication devices, which may be referred to as User Equipment (UE).

[0005] The UE can send multiple repetitions of the uplink transmission, for example, to improve the communication quality of the uplink transmission. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting demodulation reference signal (DMRS) bundling and frequency hopping. Typically, the described techniques provide the application of phase continuity to uplink transmissions within a bundling interval (e.g., a time interval or time-domain window for maintaining phase continuity across one or more transmissions). In a first example, a user equipment (UE) may determine the bundling interval for uplink channel transmission based on a transmission time interval (TTI) format pattern and bundling size. For example, a bundling interval may begin at the next available uplink TTI (e.g., an uplink or flexible TTI, a TTI configured or available for uplink transmission) after the end of a previous bundling interval, or begin at the next set of multiple uplink repetitions that satisfy one or more conditions for maintaining phase continuity after the end of a previous bundling interval, such that each bundling interval may include at least one uplink TTI.

[0007] In a second example, the UE may allocate frequency resources (e.g., frequency hopping) for uplink channel transmission repetitions within a bundled interval based on an index of the bundled interval or an index for one or more repetition transmission opportunities. For example, repetitions transmitted in a first bundled interval or a first transmission opportunity may use frequency resources (e.g., first frequency hopping) associated with the index of the first bundled interval or the first transmission opportunity, respectively. Repetitions transmitted in a second bundled interval or a second transmission opportunity may use frequency resources (e.g., second frequency hopping) associated with the index of the second bundled interval or the second transmission opportunity, respectively. In a third example, the UE may bundle (e.g., for maintaining phase continuity) one or more repetitions of uplink channel transmissions within a first bundled interval, but may not bundle one or more other repetitions of uplink channel transmissions within the same bundled interval, for example, based on one or more phase continuity rules (e.g., the time between repetitions in which the UE can maintain phase continuity). In such cases, the UE may switch frequency resources (e.g., frequency hopping) each time a phase discontinuity is experienced (e.g., within a bundled interval, or when switching between bundled intervals, or both).

[0155] User equipment (UE) can perform bundling (e.g., demodulation reference signal (DMRS) bundling) on ​​one or more repetitive sets transmitted to the uplink channel of the base station. Bundling may include maintaining phase continuity of the repetitive sets transmitted across the uplink channel, for example, to support joint channel estimation of the repetitive sets at the base station.

[0156] The bundle size can define the number of consecutive transmission time intervals (TTIs) used for a bundle interval (where a set of repeated uplink channel transmissions can be bundled). As described herein, a bundle interval can refer to the time interval or time-domain window (e.g., having a defined length) on which DMRS or other bundles (e.g., maintaining phase continuity) are applied or configured to be applied. The UE can be configured with or determine the bundle size for each set of bundle intervals that includes a bundled set of repeated uplink channel transmissions. Some bundle intervals may not include any uplink TTIs (e.g., based on a TTI format pattern), and the UE may not be able to apply DMRS bundles (e.g., maintaining phase continuity) in such bundle intervals. Additionally or alternatively, a bundle interval may include one or more uplink TTIs that may not support repeated phase continuity for uplink channel transmissions within the bundle interval (e.g., based on one or more phase continuity rules).

[0157] This disclosure provides techniques for applying phase continuity to uplink transmissions within a bundled interval, wherein a UE can be configured to identify bundled intervals and / or one or more bundled interval parameters (e.g., DMRS bundles) associated with phase continuity. The UE can identify multiple bundled intervals, which can represent multiple non-overlapping time-domain windows used for bundled uplink channel transmissions. Each bundled interval can be determined based on a semi-static timeslot (e.g., TTI) format configuration (e.g., cell-specific or UE-specific configuration). In a first example, the UE can determine the bundled interval for uplink channel transmissions based on the TTI format style and bundle size. For example, a first bundled interval can begin with a first available uplink TTI (e.g., an uplink TTI configured for or available for uplink transmissions or a flexible TTI) scheduled for transmissions used for uplink channel transmissions, or begin with multiple uplink TTIs scheduled for repeated transmissions of uplink channel transmissions that satisfy one or more conditions for maintaining phase continuity.

[0158] For example, multiple repeated transmissions of an uplink channel (e.g., satisfying one or more conditions) can support phase continuity maintenance for both the repetition of transmissions for the uplink channel and at least one other repetition of the uplink channel. In some cases, a subsequent bundling interval may begin at the next available uplink TTI (e.g., an uplink TTI configured for uplink transmission or a flexible TTI) after the end of a previous bundling interval, such that each bundling interval may include at least one uplink TTI. In some cases, a subsequent bundling interval may begin at the end of an uplink TTI associated with an uplink repetition satisfying one or more conditions, after the end of a previous bundling interval.

[0159] In the second example, the UE may allocate frequency resources (e.g., frequency hopping) for uplink channel transmission repetitions within a bundled interval based on an index of the bundled interval or an index of the transmission timing for one or more repetitions. In some cases, all repetitions transmitted in a first bundled interval may use frequency resources associated with the index of the first bundled interval (e.g., first frequency hopping). Similarly, all repetitions transmitted in a second bundled interval may use frequency resources associated with the index of the second bundled interval (e.g., second frequency hopping). In some cases, consecutive bundled intervals may be associated with consecutive indices (e.g., regardless of whether the bundled interval includes an uplink TTI). In some other cases, bundled intervals that include uplink TTIs (e.g., uplink TTIs configured for uplink transmission or flexible TTIs) may be associated with consecutive indices, while other bundled intervals (e.g., those that do not include uplink TTIs) may not be indexed. In some cases, a set of one or more transmissions may be referred to as a transmission timing and may be associated with a corresponding transmission timing index and a corresponding frequency hopping.

[0160] In the third example, the UE may bundle (e.g., for maintaining phase continuity) one or more repetitions transmitted by the uplink channel in the first bundling interval, but may not bundle one or more other repetitions transmitted by the uplink channel in the same bundling interval, for example, based on one or more phase continuity rules (e.g., the time between repetitions). In such cases, the UE may switch frequency resources (e.g., frequency hopping) each time a phase discontinuity is experienced (e.g., within the bundling interval, or when switching between bundling intervals, or both).

[0161] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. The techniques employed by the described communication device can provide benefits and enhancements to the operation of the communication device, including improved channel demodulation, communication quality, and reduced overhead. For example, the operations performed by the described communication device can provide improvements to the channel estimation and demodulation process by bundling DMRSs across multiple TTIs and / or by performing frequency hopping when bundling DMRSs. Bundling DMRSs can improve the channel estimation and demodulation process by enhancing the accuracy of channel estimation and demodulation based on shared coherence parameters (e.g., phase continuity) across the bundled DMRSs.

[0162] By transmitting a first repetition of the uplink channel in a first bundling interval and a second repetition of the uplink channel in a second bundling interval based on a corresponding start time of the second bundling interval (e.g., using one or more bundling rules or techniques described herein), channel demodulation can be performed across multiple TTIs with improved accuracy, which can improve communication quality and generally reduce communication overhead. For example, a configuration of bundling intervals having a corresponding start time corresponding to a corresponding start time of a corresponding available transmission time interval that appears after the end of a corresponding previous bundling interval in multiple bundling intervals can allow efficient identification of resources for repetition of the uplink channel, while allowing channel demodulation to be performed within the corresponding bundling interval with improved accuracy (e.g., based on a bundling interval defined according to a start time and end time that supports improved accuracy).

[0163] Additionally or alternatively, channel demodulation can also be performed across multiple TTIs with improved accuracy by transmitting a first repetition of the uplink channel in a first bundling interval and at a first frequency hopping (e.g., based on a transmission timing index, using one or more rules or techniques described herein), and a second repetition of the uplink channel in a second bundling interval and at either the first or second frequency hopping (e.g., based on a transmission timing index, using one or more rules or techniques described herein). This can improve communication quality and generally reduce communication overhead. For example, channel demodulation can be performed with improved accuracy within a corresponding bundling interval based on the use of a corresponding frequency hopping associated with the bundling interval for the transmission of the corresponding repetition of the uplink channel (e.g., based on the use of a corresponding frequency hopping that supports improved accuracy for the corresponding bundling interval).

[0164] Due to improved communication quality and reduced communication overhead, wireless devices can typically consume less power and experience lower latency during communication. Similarly, uplink communication typically experiences improved reliability due to increased accuracy in channel estimation and demodulation.

[0165] The aspects of this disclosure were initially described in the context of wireless communication systems. These aspects are further illustrated and described by way of and reference to bundling schemes, process flows, apparatus diagrams, system diagrams, and flowcharts related to DMRS bundling and frequency hopping.

[0166] Figure 1 The figure illustrates an example of a wireless communication system 100 according to aspects of this 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 communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0167] Base stations 105 can be distributed throughout a geographic area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. The coverage area 110 can be an example of a geographic area on which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0168] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Some example UE 115s are... Figure 1 It is shown in the middle. For example... Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment).

[0169] Base station 105 may communicate with core network 130 or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) (or both) via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0170] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit-NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.

[0171] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, instruments, etc.

[0172] like Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s that can sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0173] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 and one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio frequency spectrum band operating 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 coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with frequency division duplex (FDD) (e.g., paired spectrum operation) and time division duplex (TDD) (e.g., unpaired spectrum operation) component carriers.

[0174] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are negatively correlated. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate that can be used for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity used for communication with UE 115.

[0175] The time interval used for base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N... fThis can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resource can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0176] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into several time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include several symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0177] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a TTI. In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0178] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by several symbol periods and can extend across the system bandwidth or a subset of the carrier's system bandwidth. One or more control regions (e.g., CORESET) can be configured for use by a set of UEs 115. For example, one or more UEs 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner in one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to issue control information to multiple UEs 115 and a UE-specific search space set configured to issue control information to a specific UE 115.

[0179] In some examples, base station 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 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. 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.

[0180] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical keypad calling (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0181] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0182] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) routing packets or interconnecting to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP service 150 for one or more network operators. IP service 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0183] Some network devices (such as base station 105) may include sub-components, 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 UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting 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 headends and ANCs) or combined into a single network device (e.g., base station 105).

[0184] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, but the wave can penetrate structures sufficiently to enable macrocells to serve UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0185] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configurations (e.g., LAA) that combine component carriers operating in licensed bands. Operation in unlicensed spectrum can include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0186] Base station 105 or UE 115 may be equipped with multiple antennas that can 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 can 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 accessory (such as an antenna tower). In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with several rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0187] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicating via antenna elements of an antenna array such that some signals propagating in a specific orientation relative to the antenna array experience constructive interference while others experience destructive interference. Adjustments to the signals communicating via the antenna elements can include the transmitting or receiving device applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a beamforming weight set associated with a specific orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0188] Wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The Medium Access Control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide support for the establishment, configuration, and maintenance of RRC connections between UE 115 and base station 105 or core network 130 for radio bearers supporting user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0189] UE 115 can apply phase continuity to uplink transmissions within a bundled interval, for example, to support joint channel estimation at base station 105. In a first example, UE 115 can determine the bundled interval for uplink channel transmissions based on the TTI format pattern and bundle size. For example, a bundled interval can begin at the next available uplink TTI after the end of a previous bundled interval, or it can include at least one additional uplink TTI on which multiple repeated transmissions of the uplink channel satisfy one or more conditions for maintaining phase continuity after the end of a previous bundled interval, such that each bundled interval can include at least one uplink TTI. In a second example, UE 115 can allocate frequency resources (e.g., frequency hopping) for repeated uplink channel transmissions within a bundled interval based on an index of the bundled interval or an index for the timing of one or more repeated transmissions. In a third example, UE 115 can not bundle certain repeated uplink channel transmissions within the same bundled interval, for example, based on one or more phase continuity rules (e.g., the time between repeated transmissions on which UE 115 can maintain phase continuity). In such cases, UE 115 can switch frequency resources (e.g., frequency hopping) each time a phase discontinuity is experienced (e.g., within a bundled interval, or when switching between bundled intervals, or both).

[0190] Figure 2 The figure illustrates an example of a bundling scheme 200 according to aspects of this disclosure. Bundling scheme 200 may illustrate one or more techniques for enhancing or increasing coverage of uplink shared channel transmissions (e.g., transmissions on the Physical Uplink Shared Channel (PUSCH), transmissions on the uplink control channel (e.g., transmissions on the Physical Uplink Control Channel (PUCCH)), or both.

[0191] For example, some channels may experience lower transmission rates or other communication quality bottlenecks. Such channels may include channels in frequency range 1 (FR1), such as PUSCH for eMBB (e.g., for FDD or TDD with the format “DDDSU”, “DDDSUDDSUU”, or “DDDDDDDSUU”), PUSCH for Voice over IP (VoIP) (e.g., for FDD or TDD with the format “DDDSU” or “DDDSUDDSUU”), PUCCH format 3 with 11 bits, or PUCCH format 3 with 22 bits, and so on. Such channels may additionally or alternatively include channels in frequency range 2 (FR2) (e.g., urban 28 GHz), such as PUSCH for eMBB (e.g., for TDD with “DDDSU” or “DDSU” format), PUSCH for VoIP (e.g., for TDD with “DDDSU” or “DDSU” format), PUCCH format 3 with 11 bits, or PUCCH format 3 with 22 bits, etc. As described herein, “D” may denote a TTI configured for downlink transmission in TDD format (e.g., unpaired spectrum operation), “U” may denote a TTI configured for uplink transmission in TDD format, and “S” may denote a flexible TTI in TDD format (e.g., a TTI configured for downlink, uplink, or both).

[0192] As described herein, a flexible TTI (e.g., a timeslot) may have a dynamic timeslot indication to indicate whether the flexible TTI is associated with an uplink, downlink, or both. This indication may be a timeslot format indication (SFI) in downlink control information (DCI) (e.g., DCI format 2_0), where the SFI may indicate the format used for the flexible TTI. As described herein, a TDD format (e.g., unpaired spectrum operation) may be an example or representation of a TDD TTI format style, which may include styles of “D,” “U,” and “S” TTIs used for TDD transmission.

[0193] To enhance or increase coverage of uplink shared channel and / or uplink control channel transmissions, PUSCH repetition types (e.g., type A) may have an increased number of PUSCH repetitions (e.g., maximum repetition count), where the repetition count may be counted based on available uplink time slots (e.g., based on TDD TTI format). Signaling may also be configured to support PUSCH repetition for Random Access Message 3 (msg3) (e.g., type APUSCH repetition). Additionally or alternatively, coverage may be increased by supporting transport block (TB) processing on multi-time slot PUSCH transmissions, where the TB size (TBS) may be determined based on multiple time slots and may be transmitted over multiple time slots.

[0194] In some cases, to increase coverage, joint channel estimation can be performed on multiple PUSCH transmissions, for example, based on conditions used to maintain power consistency and phase continuity. Joint channel estimation may include optimization of DMRS location and / or granularity, and may additionally or alternatively include inter-slot frequency hopping utilizing inter-slot bundling (e.g., DMRS bundling) to support joint channel estimation. In some cases, to increase coverage, signaling can be configured to support dynamic PUCCH repetition factor indication and / or may support DMRS bundling through PUCCH repetition (e.g., repetition of PUCCH transmissions).

[0195] When performing joint channel estimation, as illustrated by, for example, bundling scheme 202, the receiving device (e.g., base station 105) can jointly process DMRS from multiple uplink transmissions (e.g., multiple PUSCH transmissions or multiple PUCCH transmissions). For example, DMRS from multiple PUSCH transmissions can be jointly processed, or DMRS from multiple PUCCH transmissions can be jointly processed, but joint processing cannot be performed on DMRS from both PUSCH and PUCCH transmissions. Each transmission can be received in a corresponding time slot or TTI, where each TTI can include 14 symbols (e.g., Figure 2 (Numbers 0 to 13 in the original text). A transmitting device (e.g., UE 115) can maintain phase continuity across multiple uplink transmissions (e.g., multiple PUSCH or multiple PUCCH transmissions). Maintaining phase continuity may include maintaining one or more conditions for multiple uplink transmissions, such as maintaining the same frequency resource allocation (e.g., the same resource block (RB)), the same transmit power, the same spatial transmission relationship, the same antenna port (e.g., for DMRS), and the same precoding (e.g., for DMRS).

[0196] For example, joint channel estimation of multiple repetitions (e.g., across multiple time slots or TTIs) transmitted across the uplink can improve the accuracy of channel estimation compared to other schemes that support channel estimation using a single time slot or TTI (such as bundling scheme 201), which can lead to improved communication quality. In such cases, joint channel estimation can occur across multiple consecutive or discontinuous transmissions (e.g., consecutive or discontinuous TTIs), such that each TTI shown in bundling scheme 202 can be consecutive or discontinuous.

[0197] Figure 3 The figure illustrates an example of a bundling scheme 300 according to aspects of this disclosure. Bundling scheme 300 may support, for example, as referenced... Figure 2 Described DMRS bundling for joint channel estimation. Bundling scheme 300 can illustrate several repeated time slots or TTIs (e.g., numbered from 0 to 24) on which UE 115 can transmit uplink channels (e.g., PUSCH or PUCCH transmissions), where UE 115 can represent a reference. Figure 1 and 2 The UE 115 is described. A TTI marked "D" may represent a TTI configured for downlink transmission, a TTI marked "U" may represent a TTI configured for uplink transmission, and a TTI marked "S" may represent a flexible TTI configured for uplink transmission, downlink transmission, or both.

[0198] Bundling scheme 300 can represent the TDD format “DDDSUDDSUU” (e.g., a TTI format pattern that follows the “DDDSUDDSUU” pattern, with repeated downlink, uplink, and flexible TTI on the same carrier). It will be understood that while the “DDDSUDDSUU” format is described herein, the same examples can be applied to other TDD formats (e.g., TTI format patterns) or other transmission formats (e.g., FDD format, paired spectrum operation) without departing from the scope of this disclosure.

[0199] The bundling interval described herein can be defined such that UE 115 can transmit coherently in an uplink subject to one or more phase continuity conditions. In some cases, for example... Figure 3As shown, a bundle interval can also be referred to as a bundle. All bundle intervals can have the same bundle size (e.g., K), which can be counted as the number of consecutive time slots or TTIs from the start time of the bundle interval. The bundle size can be configured to UE 115 (e.g., via RRC signaling or dynamically via DCI), or it can be implicitly determined by UE 115 based on repetitions transmitted on the uplink channel. For example, UE 115 can determine the bundle size based on the number of repetitions transmitted on the uplink channel (e.g., using a formula or equation that includes the number of repetitions as a variable).

[0200] In some examples, the bundle size (e.g., K) may include four TTIs or eight TTIs, for example, as Figure 3 Different bundling configurations (e.g., K equals four and K equals eight) are shown. Additionally or alternatively, the bundle size may include any number of TTIs without departing from the scope of this disclosure. In some cases, a larger K value may result in more uplink transmission TTIs (e.g., “U” TTIs) within the bundle interval, and may also result in a greater challenge in maintaining phase continuity of uplink transmissions across the bundle interval; thus, the determination of the bundle size K may be based on one or both of these factors.

[0201] In some cases, such as based on one or more phase continuity rules (e.g., based on a larger bundle size), phase continuity may not be maintained across bundles or bundle intervals. In such cases, bundles or bundle intervals can still be defined and used as a period of time or duration for performing UE operations (such as adjusting the frequency before the next uplink channel transmission, etc.).

[0202] Figure 3 An example of a baseline bundling interval design can be illustrated, where bundling intervals can be arranged without any time gaps between consecutive bundling intervals (e.g., consecutive). In such cases, some bundlings (e.g., bundling 4 when K equals 4) may not include any TTIs used for uplink transmission (e.g., may not include time slots or TTIs configured as "U" TTIs), which could affect frequency hopping across bundling intervals.

[0203] Figure 4 The figure illustrates an example of a wireless communication system 400 according to aspects of this disclosure. In some examples, the wireless communication system 400 may implement certain aspects of the wireless communication system 100. In some examples, the wireless communication system 400 may additionally or alternatively implement certain aspects of the bundling scheme 200 or 300. For example, the wireless communication system 400 may include a base station 105-a and a UE 115-a, which may represent references to Figure 1-3Examples of base station 105 and UE 115 described herein. As described herein, UE 115-a may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more repeated sets transmitted to the uplink channel of base station 105-a.

[0204] As described herein, transmitting a repetition of uplink channel transmission may include transmitting an uplink message on each of the repetitions. This uplink message may be a PUSCH or PUCCH transmission, wherein each uplink message may include the same TB or may include up to several different TBs per repetition. Each uplink message (e.g., a repetition of uplink channel transmission) may be transmitted via a corresponding TTI.

[0205] UE 115-a can receive control signaling 405 (e.g., RRC signaling) from base station 105-a, which can be configured using a TDD (e.g., unpaired spectrum operation) TTI format pattern (e.g., a TDD pattern of repeated "D", "S", and / or "U" TTIs). UE 115-a can also receive control messages 410 (e.g., signaled via RRC or DCI) from base station 105-a, which can schedule uplink channel transmissions and instruct UE 115-a to transmit multiple repetitions of uplink channel transmissions (e.g., the number of repetitions can be indicated). In some cases, control message 410 (e.g., a DCI carrying SFI) can be configured using a TDD TTI format pattern (e.g., a TDD pattern of repeated "D", "S", and / or "U" TTIs).

[0206] For reference Figure 3 As described, UE 115-a can be configured to or determine a bundle size for each of one or more bundled repeats of uplink channel transmissions. For example, UE 115-a can receive control signaling 405 (e.g., RRC signaling) or control message 410 (e.g., DCI) indicating the bundle size, or UE 115-a can determine the bundle size based on the number of repeats of uplink channel transmissions indicated by control message 410. In some cases, certain bundled intervals may not include any uplink TTIs (e.g., based on a TDD TTI format pattern), and the UE may not be able to apply DMRS bundling (e.g., maintaining phase continuity) in such bundled intervals. Additionally or alternatively, bundled intervals may include one or more uplink TTIs that may not support phase continuity for uplink channel transmissions (e.g., based on one or more phase continuity rules, such as the time between repeats based on a larger bundled interval).

[0207] This disclosure provides techniques for applying phase continuity to uplink transmissions within a bundled interval, wherein UE 115-a can be configured to identify bundled intervals and / or bundled interval parameters (e.g., DMRS bundles) associated with phase continuity. In a first example, UE 115-a can determine the bundled interval for uplink channel transmissions based on a TDD TTI format pattern and a bundled interval size. For example, the first bundled interval can begin with a first available uplink TTI (e.g., an uplink TTI configured for or available for uplink transmission or a flexible TTI) scheduled for transmissions on the uplink channel, or begin with a first uplink TTI scheduled for transmissions on the uplink channel that satisfy one or more conditions for maintaining phase continuity. Because in some cases the first available uplink TTI can be a flexible TTI (e.g., based on an indication in an SFI), in such cases, the bundled interval configuration or format can be based on an SFI indicating the format of a flexible TTI.

[0208] The first bundling interval may, for example, include the transmission of a first repetition 415 or a second repetition 420 transmitted via the uplink channel (e.g., from UE 115-a to base station 105-a). In some cases, a subsequent bundling interval may begin after the end of a previous bundling interval with a first available uplink TTI (e.g., an uplink TTI or flexible TTI configured for uplink transmission), such that each bundling interval may include at least one uplink TTI. For example, UE 115-a may transmit a second repetition 420 transmitted via the uplink channel in the uplink TTI of a second bundling interval (e.g., to base station 105-a). Additionally or alternatively, UE 115-a may transmit a second repetition 420 transmitted via the uplink channel after the first repetition 415 and having phase continuity with the first repetition 415 (e.g., based on transmission within the same bundling interval) in the uplink TTI of the first bundling interval (e.g., to base station 105-a).

[0209] In some cases, a subsequent bundling interval may begin after the end of a previous bundling interval, with the next available uplink TTI of a repeat 420 satisfying one or more conditions for phase continuity with another repeat 420. For example, UE 115-a may transmit a first repeat 415 without phase continuity, transmitted via the uplink channel, and may transmit a second repeat 420 transmitted via the uplink channel in the uplink TTI of the first bundling interval (e.g., to base station 105-a).

[0210] In the second example, UE 115-a may allocate frequency resources (e.g., frequency hopping) for uplink channel transmission repetitions within a bundled interval based on an index of the bundled interval or an index of the transmission timing for one or more repetitions. A set of one or more transmissions (e.g., consecutive transmissions) may be referred to as a transmission timing and may be associated with a corresponding transmission timing index and a corresponding frequency hopping. In some cases, all repetitions transmitted in a first bundled interval or a first transmission timing may use frequency resources (e.g., first frequency hopping) associated with the index of the first bundled interval or the first transmission timing, respectively. Similarly, all repetitions transmitted in a second bundled interval or a second transmission timing may use frequency resources (e.g., second frequency hopping) associated with the index of the second bundled interval or the second transmission timing, respectively.

[0211] For example, UE 115-a may transmit the first repeat 415 and the second repeat 420 (e.g., to base station 105-a) within a first bundling interval or a first transmission timing and using a first frequency hopping. In another example, UE 115-a may transmit the first repeat 415 (e.g., to base station 105-a) within a first bundling interval or a first transmission timing and using a first frequency hopping, and may transmit the second repeat 420 within a second bundling interval or a second transmission timing using a second frequency hopping. In some cases, all bundling intervals may be associated with a continuous index (e.g., regardless of whether the bundling interval includes an uplink TTI), or bundling intervals that include an uplink TTI (e.g., an uplink TTI or flexible TTI configured for uplink transmission) may be associated with a continuous index, while other bundling intervals (e.g., those that do not include an uplink TTI) may not be indexed. All transmission timings may be associated with a continuous index (e.g., because each transmission timing may include at least one uplink TTI).

[0212] In the third example, UE 115-a may bundle (e.g., for maintaining phase continuity) one or more repetitions transmitted on the uplink channel within a first bundling interval, but may not bundle one or more other repetitions transmitted on the uplink channel within the same bundling interval, for example, based on one or more phase continuity rules (e.g., time between repetitions). In such cases, UE 115-a may switch frequency resources (e.g., frequency hopping) each time a phase discontinuity is experienced (e.g., within a bundling interval, or when switching between bundling intervals, or both). For example, UE 115-a may transmit a first repetition 415 and a second repetition 420 within the first bundling interval, but without phase continuity. In this example, the first repetition 415 may be transmitted with a first frequency hopping, while the second repetition 420 may be transmitted with a second frequency hopping (e.g., based on being transmitted without phase continuity).

[0213] Figure 5 The figure illustrates an example of a bundling scheme 500 according to aspects of this disclosure. In some examples, the bundling scheme 500 may implement or be implemented by certain aspects of the wireless communication system 100 or 400. In some examples, the bundling scheme 500 may additionally or alternatively implement or be implemented by certain aspects of the bundling scheme 200 or 300. For example, the bundling scheme 500 may be implemented by a base station 105 and a UE 115, which may represent references to... Figure 1-4 Corresponding examples of base station 105 and UE 115 are described herein. As described herein, UE 115 may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more repeated sets transmitted to the uplink channel of base station 105.

[0214] Figure 5 The diagram illustrates several repeated transmissions of TTI 505 (e.g., time slots or micro-slots) for uplink channel transmission. TTI 505 can be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern 510, which can be configured by the base station 105 and can indicate the patterns of downlink (“D”), uplink (“U”), and flexible (“S”) TTI 505. Although Figure 5 The “DDDSUDDSUU” TDD TTI format style is shown, but for understanding, please refer to [reference needed]. Figure 5 The same examples described can be applied to other TDD formats (e.g., TTI format styles) or other transmission formats (e.g., FDD format, paired spectrum operation) without departing from the scope of this disclosure. Bundling (also referred to as bundling interval 520) can be used to transmit a set of repetitions 515 transmitted on the uplink channel with phase continuity. The bundling interval may begin at a start time and can be defined by the number of consecutive TTIs 505 starting at the start time (e.g., the bundling size).

[0215] In some cases (e.g., as referenced) Figure 3 and 4 As described, for example, based on a baseline bundling scheme, the bundling interval may be misaligned or may not include TTI 505 available for uplink transmission (e.g., bundling 4). Accordingly, as referenced Figure 4As described, the start of a bundling interval 520 (e.g., bundling interval k+1) can be the start of the first available uplink TTI 505 of a repeating 515 for uplink channel transmission (e.g., PUSCH or PUCCH transmission) after the end of a previous (e.g., immediately preceding) bundling interval 520 (e.g., bundling interval k) (such as after the end of the last available TTI 505 of the previous bundling interval 520). Additionally or alternatively, the start of a bundling interval 520 (e.g., bundling interval k+1) can be the start of the first flexible TTI 505 (e.g., "S" slot) of a repeating pattern available for uplink channel transmission after the end of a previous (e.g., immediately preceding) bundling interval 520 (e.g., bundling interval k). The first bundling interval 520 (e.g., bundling 0, or bundling interval k=0, such as the first repetition for uplink channel transmission) may begin with the first available uplink TTI 505 or flexible TTI 505 (e.g., TTI 4) of the first or initial repetition of transmission scheduled for uplink channel transmission. Such techniques for determining the start positioning for bundling interval 520 may be indicated by base station 105 or may be configured at UE 115 (e.g., based on wireless communication standards).

[0216] As described herein, Figure 5 The diagram illustrates the starting location of a bundle interval of 520 based on different bundle sizes (e.g., K values), where the bundle size can be configured by the network or implicitly determined. For example, Figure 5 The diagram illustrates the initial positioning of the bundle interval 520 using K values ​​of four and eight. A K value of four allows the bundle interval 520 to begin at TTI 4, TTI 8, TTI 14, TTI 18, and TTI 24 (e.g., with...). Figure 3 Compared to the baseline bundle intervals shown, which begin with TTI 4, TTI 8, TTI 12, TTI 16, TTI 20, and TTI 24). A K value of eight allows a bundle interval of 520 to begin with TTI 4, TTI 14, and TTI 24 (e.g., compared to the baseline bundle intervals beginning with TTI 4, TTI 8, TTI 12, TTI 16, TTI 20, and TTI 24). Although Figure 5 The diagram illustrates K values ​​of four and eight, but for understanding, this article refers to... Figure 5 The same examples described can be applied to other values ​​of K without departing from the scope of this disclosure.

[0217] Figure 6The figure illustrates an example of a bundling scheme 600 according to aspects of this disclosure. In some examples, the bundling scheme 600 may implement or be implemented by certain aspects of the wireless communication system 100 or 400. In some examples, the bundling scheme 600 may additionally or alternatively implement or be implemented by certain aspects of the bundling scheme 200 or 300. For example, the bundling scheme 600 may be implemented by a base station 105 and a UE 115, which may represent references to... Figure 1-5 Corresponding examples of base station 105 and UE 115 are described herein. As described herein, UE 115 may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more repeated sets transmitted to the uplink channel of base station 105.

[0218] Figure 6 The diagram illustrates several TTIs 605 (e.g., time slots or micro-slots) for repeated transmissions in the uplink channel. TTIs 605 may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern 610 as described herein, which may represent the “DDDSUDDSUU” TDD TTI format pattern. It will be understood that... (Refer to...) Figure 6 The same examples described can be applied to other TDD formats (e.g., TDD TTI format style) or other transmission formats (e.g., FDD format, pairwise spectrum operation) without departing from the scope of this disclosure. Bundling (also referred to as bundling interval 620) can be used to transmit a set of repeats 615 of uplink channel transmission with phase continuity. Bundling interval 620 can begin at a start time and can be defined by the number of consecutive TTIs 605 starting at the start time (e.g., bundle size). As described herein, a first bundling interval 620 (e.g., bundle 0) can begin with the first available uplink TTI 605 (e.g., TTI 4) or flexible TTI 605 scheduled for transmission of the first or initial repeat 615 of uplink channel transmission.

[0219] In some cases, baseline binding interval schemes can be used, and as referenced... Figure 3 and 4As described, certain bundled intervals 620 (e.g., bundle 4) may not have any uplink TTI 605 (e.g., or a flexible TTI available for uplink transmission) for repetition 615 of uplink channel transmission. Thus, frequency hopping (e.g., changing transmit frequency resources or frequency positions) may not occur within bundled intervals 620 that do not include uplink TTI 605. As described herein, frequency hopping may include changing the repetition frequency position of uplink channel transmission (e.g., changing to a different RB) such that phase continuity may not be maintained after frequency hopping (e.g., based on transmission using a different frequency allocation).

[0220] In cases where the bundling interval 620 does not include any uplink TTI 605 (e.g., or a flexible TTI 605 for uplink transmission), the UE 115 can determine the frequency hopping 625 (e.g., frequency location or resource) for each repetition 615 used for uplink channel transmission based on the index of the corresponding bundling interval 620. This index may differ from the actual bundling number (e.g., different from bundling 0, bundling 1, etc.). For example, the UE 115 may transmit the corresponding repetition 615 for uplink channel transmission in frequency hopping 1 (e.g., a first frequency resource, or a first RB) for even-numbered bundling intervals 620 (e.g., bundling intervals 620 with even-numbered indexes). Similarly, the UE 115 may transmit the corresponding repetition 615 for uplink channel transmission in frequency hopping 2 (e.g., a second frequency resource, or a second RB) for odd-numbered bundling intervals 620 (e.g., bundling intervals 620 with odd-numbered indexes).

[0221] UE 115 can receive signaling from base station 105 indicating frequency hopping 1 and frequency hopping 2, etc. For example, UE 115 can receive (e.g., via one or more DCI parameters) the start value (e.g., frequency value) of frequency hopping 1 and an indication of the offset between frequency hopping 1 and frequency hopping 2. In another example, UE 115 can receive indications of the start value (e.g., frequency value) of frequency hopping 1 and the start value (e.g., frequency value) of frequency hopping 2.

[0222] In the first example (e.g., as shown in Option 1), the count of bundle intervals 620 (e.g., bundle interval indexes) can be based on bundle intervals having at least one uplink or flexible TTI 605 with transmissions of repeat 615 for uplink channel transmission. Accordingly, in Option 1, bundle 0 can be associated with index 0, bundle 1 can be associated with index 1, and so on, up to bundle 3 (e.g., because each of these bundles may include at least one uplink or flexible TTI 605 with transmissions of repeat 615 for uplink channel transmission). In Option 1, bundle 4 may not be associated with a corresponding index, for example, because bundle 4 may not include at least one uplink or flexible TTI 605 with transmissions of repeat 615 for uplink channel transmission. Accordingly, bundle 5 (e.g., after bundle 4) can be associated with index 4. UE115 can transmit repeat 615 for uplink channel transmission at frequency hopping 625 corresponding to the bundle interval index. For example, uplink repeat 0 can be sent in frequency 1, uplink repeats 1 and 2 can be sent in frequency 2, uplink repeat 3 can be sent in frequency 1, uplink repeats 4 and 5 can be sent in frequency 2, and uplink repeat 6 (e.g. in bundle 5) can be sent in frequency 1 (e.g., corresponding to index 4 or an even index).

[0223] In the second example (e.g., as shown in option 2), the count of bundled intervals 620 (e.g., bundled interval index) can be based on all bundled intervals 620, regardless of whether a bundled interval 620 has an uplink or flexible TTI 605 for transmitting repeat 615 for uplink channel transmission. Accordingly, bundle 0 can be associated with index 0, bundle 1 can be associated with index 1, and so on, up to bundle 5 (e.g., or further), even though bundle 4 may not include at least one uplink or flexible TTI 605 for transmitting repeat 615 for uplink channel transmission. UE 115 can transmit repeat 615 for uplink channel transmission at frequency hopping 625 corresponding to the bundled interval index. For example, uplink repeat 0 can be transmitted at frequency hopping 1, uplink repeats 1 and 2 can be transmitted at frequency hopping 2, and so on. In this example, bundle 5 can be associated with index 5 such that uplink repeats 4 and 5 (e.g., in bundle 3) can be transmitted at frequency hopping 2 and uplink repeat 6 (e.g., in bundle 5) can also be transmitted at frequency hopping 2 (e.g., associated with index 5 or an odd index).

[0224] Figure 7The figure illustrates an example of a bundling scheme 700 according to aspects of this disclosure. In some examples, the bundling scheme 700 may implement or be implemented by certain aspects of the wireless communication system 100 or 400. In some examples, the bundling scheme 700 may additionally or alternatively implement or be implemented by certain aspects of the bundling scheme 200 or 300. For example, the bundling scheme 700 may be implemented by a base station 105 and a UE 115, which may represent references to... Figure 1-6 Corresponding examples of base station 105 and UE 115 are described herein. As described herein, UE 115 may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more repeated sets transmitted to the uplink channel of base station 105.

[0225] Figure 7 The diagram illustrates several TTIs 705 (e.g., time slots or micro-slots) used for repeated transmissions in the uplink channel. TTIs 705 may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern 710 as described herein, which may represent the “DDDSUDDSUU” TDD TTI format pattern. It will be understood that... (Refer to...) Figure 7 The same examples described can be applied to other TDD formats (e.g., TTI format styles) or other transmission formats (e.g., FDD format, pairwise spectrum operation) without departing from the scope of this disclosure. Bundling (also referred to as bundling interval 720) can be used to transmit a set of repeats 715 of uplink channel transmissions with or without phase continuity. Bundling interval 720 can begin at a start time and can be defined by the number of consecutive TTIs 705 beginning at the start time (e.g., bundle size). As described herein, a first bundling interval 720 (e.g., bundle 0) can begin with the first available uplink TTI 705 (e.g., TTI 4) or flexible TTI 705 scheduled for transmission of the first or initial repeat 715 of uplink channel transmission.

[0226] In some cases, baseline binding interval schemes can be used, and as referenced... Figure 3 and 4Described, certain repetitions 715 transmitted by the uplink channel in a bundling interval 720 (e.g., bundling 0) may be bundled together, while certain repetitions 715 transmitted by the uplink channel in the same bundling interval 720 may not be bundled, for example, due to one or more phase continuity rules. For example, in bundling 0, repetition 0 may not be bundled with either repetition 1 or repetition 2 (e.g., based on one or more phase continuity rules), while repetitions 1 and 2 may be bundled. In one example, repetitions 1 and 2 may be too far apart from repetition 0 (e.g., in time) for phase continuity to be maintained (e.g., based on one or more phase continuity rules that the UE can maintain for repetitions that are separated in time by less than a defined time interval or in frequency by less than a defined frequency range), although other examples of phase continuity rules may also apply to the same or similar examples of phase discontinuities within the bundling interval 720.

[0227] In cases where some repetitions 715 transmitted on the uplink channel within a bundling interval 720 may not be bundled, frequency hopping may or may not be supported within the bundling interval 720. In a first example (e.g., option 1), UE 115 may determine a frequency hopping 725 for repetitions 715 transmitted on the uplink channel within the bundling interval 720 such that all repetitions 715 within the same bundling interval 725 may use the same frequency hopping 725. For example, UE 115 may transmit all repetitions 715 transmitted on the uplink channel within bundle 0 using frequency hopping 1 (e.g., a first frequency resource or a first RB). Similarly, UE 115 may transmit all repetitions 715 transmitted on the uplink channel within bundle 1 using frequency hopping 2 (e.g., a second frequency resource or a second RB).

[0228] In a second example (e.g., option 2), UE 115 may determine the frequency hopping 725 for repetitions 715 transmitted via the uplink channel within the bundling interval 720, such that repetitions 715 transmitted via the uplink channel with phase continuity (e.g., bundled repetitions 715) use the same frequency hopping 725, while repetitions 715 transmitted via the uplink channel without phase continuity (e.g., unbundled repetitions 715) use different frequency hopping 725. For example, UE 115 may transmit repetition 0 with frequency hopping 1 and repetitions 1 and 2 with frequency hopping 2. Determining the frequency hopping 725 for the first repetition 715 transmitted via the uplink channel in the next bundling interval 720 may depend on the frequency hopping 725 of the last repetition 715 in the previous bundling interval 720 (e.g., it may be a different frequency hopping 725 than the last repetition 715). For example, UE 115 can transmit repeats 1 and 2 at frequency hopping 2 (e.g., in bundle 0) and can transmit repeat 3 at frequency hopping 1 based on changing or switching the bundle interval 720 (e.g., in bundle 1).

[0229] UE 115 can receive signaling from base station 105 indicating frequency hopping 1 and frequency hopping 2, etc. For example, UE 115 can receive (e.g., via one or more DCI parameters) the start value (e.g., frequency value) of frequency hopping 1 and an indication of the offset between frequency hopping 1 and frequency hopping 2. In another example, UE 115 can receive indications of the start value (e.g., frequency value) of frequency hopping 1 and the start value (e.g., frequency value) of frequency hopping 2.

[0230] Figure 8 The figure illustrates an example of a bundling scheme 800 according to aspects of this disclosure. In some examples, the bundling scheme 800 may implement or be implemented by certain aspects of the wireless communication system 100 or 400. In some examples, the bundling scheme 800 may additionally or alternatively implement or be implemented by certain aspects of the bundling scheme 200 or 300. For example, the bundling scheme 800 may be implemented by a base station 105 and a UE 115, which may represent references to... Figure 1-7 Corresponding examples of base station 105 and UE 115 are described herein. As described herein, UE 115 may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more sets of repetitions 815 transmitted to the uplink channel of base station 105.

[0231] Figure 8 The diagram illustrates several TTIs 805 (e.g., time slots or micro-slots) for the transmission of repetition 815 for uplink channel transmission. TTIs 805 may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern 810 as described herein, which may represent the “DDDSUDDSUU” TDD TTI format pattern. It will be understood that... (Refer to...) Figure 8 The same examples described can be applied to other TDD formats (e.g., TDD TTI format style) or other transmission formats (e.g., FDD format, pairwise spectrum operation) without departing from the scope of this disclosure. Bundles (also referred to as bundle interval 820) can be used to transmit a set of repeats 815 of uplink channel transmission with phase continuity. Bundle interval 820 may begin at a start time and may be defined by the number of consecutive TTIs 805 starting at the start time (e.g., bundle size). As described herein, a first bundle interval 820 (e.g., bundle 0) may begin with a first available uplink TTI 805 (e.g., TTI 4) or flexible TTI 805 scheduled for transmission of the first or initial repeat 815 of uplink channel transmission that satisfies one or more phase continuity conditions.

[0232] For example, the bundling interval 820 may include two or more uplink TTIs 805 for transmission of repetitions 815 available for uplink channel transmission, wherein the two or more uplink TTIs 805 include uplink channel transmission repetitions 815 that satisfy one or more phase continuity conditions. Phase continuity conditions may include maintaining modulation order among repetitions 815 in the two or more uplink TTIs 805, maintaining the same RB allocation (e.g., length and frequency positioning) among repetitions 815 in the two or more uplink TTIs 805, maintaining the same beam (e.g., no beam switching, such as for FR2) among repetitions 815 in the two or more uplink TTIs 805, maintaining the same transmit power level for repetitions 815 in the two or more uplink TTIs 805, or any combination thereof.

[0233] In some cases, the phase continuity condition may include the following condition: two or more uplink TTIs 805 and corresponding repetitions 815 are consecutive. In some cases, the phase continuity condition may include the following condition: repetitions 815 have non-zero time gaps between repetitions 815, where downlink reception is not scheduled during non-zero time gaps. In some cases, maintaining the same transmit power level may be applied to component carriers (CCs) so that no change occurs in power control parameters. Similarly, maintaining the same transmit power level may be applied to CCs that are not affected by one or more other concurrent CCs configured for inter-band carrier aggregation or dual connectivity of the same UE 115 with dynamic power sharing, so that no change in transmit power level occurs for any configured CCs that are part of the configured intra-band carrier aggregation or dual connectivity. Furthermore, one or more phase continuity conditions may indicate that intra-TTI and inter-TTI frequency hopping is not supported within the bundling interval 820.

[0234] In some cases, baseline bundling interval schemes can be adopted (e.g., K=4 and the bundling intervals 820 are directly connected), and as referenced Figure 3 and 4 As described, certain bundle intervals 820 (e.g., bundle 4) may not have any uplink TTI 805 (e.g., or a flexible TTI that can be used for uplink transmission) for the transmission of repeating 815 for uplink channel transmission. In some cases, as referenced Figure 6As described, another bundling interval scheme can be adopted (e.g., K=4 and the bundling interval 820 includes one or more uplink or flexible TTIs 805). In such cases, some bundling intervals 820 (e.g., bundling 0, 3) may not have any uplink TTIs 805 (e.g., or flexible TTIs that can be used for uplink transmission) with any repeats 815 that satisfy one or more conditions for phase continuity.

[0235] In such cases, the nth window (e.g., the nth bundling interval 820) may begin, for example, after the (n-1)th window (e.g., bundling interval 820), with a first available TTI 805 (e.g., uplink TTI 805 or flexible TTI 805) for uplink channel transmission. The first available repetition 815 may be bundled with subsequent repetitions 815 of uplink channel transmission within the nth window (e.g., within the bundling interval 820), for example, based on satisfying one or more phase continuity conditions for bundling. For example, the first bundling interval 820 (e.g., bundling 0) may begin with TTI 8 and may continue until TTI 11, based on bundling 0 comprising TTIs 8 and 9, both of which can be configured for uplink channel transmission, wherein the uplink channel transmissions in TTIs 8 and 9 satisfy one or more phase continuity conditions. Bundling (e.g., applying bundling interval 820) can skip TTIs 4 and 14, which includes repetitions 815 that may not satisfy one or more phase continuity conditions with at least one other TTI 805. A second bundling interval 820 (e.g., bundling 1) can begin at TTI 18 and continue to TTI 21, based on the fact that bundling 1 includes TTIs 18 and 19, both of which can be configured for uplink channel transmission, wherein TTIs 18 and 19 include repetitions 815 that satisfy one or more phase continuity conditions.

[0236] Figure 9 The figure illustrates an example of a bundling scheme 900 according to aspects of this disclosure. In some examples, the bundling scheme 900 may implement or be implemented by certain aspects of the wireless communication system 100 or 400. In some examples, the bundling scheme 900 may additionally or alternatively implement or be implemented by certain aspects of the bundling scheme 200 or 300. For example, the bundling scheme 900 may be implemented by a base station 105 and a UE 115, which may represent references to... Figure 1-7 Corresponding examples of base station 105 and UE 115 are described herein. As described herein, UE 115 may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more sets of repetitions 915 transmitted to the uplink channel of base station 105.

[0237] Figure 9 The diagram illustrates several TTIs 905 (e.g., time slots or micro-slots) for the transmission of repeating 915 for uplink channel transmission. TTIs 905 may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern 910 as described herein, which may represent the “DDDSUDDSUU” TDD TTI format pattern. It will be understood that... (Refer to...) Figure 9 The same examples described can be applied to other TDD formats (e.g., TDD TTI format style) or other transmission formats (e.g., FDD format, pairwise spectrum operation) without departing from the scope of this disclosure. Bundling (also referred to as bundling interval 920) can be used to transmit a set of repeating 915 uplink channel transmissions with phase continuity. Bundling interval 920 can begin at a start time and can be defined by the number of consecutive TTIs 905 beginning at the start time (e.g., bundling size). As described herein, for example, as referenced... Figure 8 Described, a first bundling interval 920 (e.g., bundling 0) may begin with a first available uplink TTI 905 (e.g., TTI 4) or flexible TTI 905 scheduled for transmission of the first or initial repeat 915 of an uplink channel to satisfy one or more phase continuity conditions. For example, a first bundling interval 920 (e.g., bundling 0) may begin with TTI 8, based on the fact that bundling 0 includes TTIs 8 and 9 (e.g., satisfying one or more phase continuity rules). Similarly, a second bundling interval (e.g., bundling 1) may begin with TTI 18, based on the fact that bundling 1 includes TTIs 18 and 19 (e.g., satisfying one or more phase continuity rules).

[0238] In such cases, the frequency hopping 925 for the repetition 915 of the uplink channel can be determined based on an index of the associated transmission timing 930 (e.g., which may be independent of the bundling). For example, one or more transmission timings can be defined, where each transmission timing 930 may have a corresponding index. Each repetition 915 of the uplink channel within the bundling interval 920 may belong to the same transmission timing 930, while each repetition 915 of the uplink channel outside the bundling interval 920 may have its own transmission timing 930. For example, a first transmission timing 930 (e.g., TO 0) may include the first repetition 915 in TTI 4, where the first repetition 915 may not be bundled with any other repetition 915 (e.g., it may be outside the bundling interval 920). The first repetition 915 of the first transmission timing 930 may not satisfy one or more phase continuity conditions for bundling (e.g., within the bundling interval 920) because the first repetition 915 may be scheduled for transmission in TTI 905 that is more than a threshold number of TTI 905 away from another repetition 915 (e.g., if the bundling interval 920 is to include the first repetition 915, then the first repetition 915 will be the only repetition 915 within the bundling interval 920).

[0239] The second transmission timing 930 (e.g., TO 1) may include a second and a third repetition 915 in TTI 8 and 9 respectively, wherein the second and third repetitions 915 may be bundled together in bundle 0. For example, TTI 8 and 9 (e.g., for the transmission of the second and third repetitions 915) may include repetitions 915 that satisfy one or more phase continuity conditions (e.g., possibly continuous transmissions), and therefore the second and third repetitions 915 may be bundled together in bundle 0 (e.g., the first bundle interval 920).

[0240] The frequency hopping 925 used for each repetition can be based on the corresponding transmission timing index. For example, frequency hopping 1 can be applied to all even indices, while frequency hopping 2 can be applied to all odd indices, and vice versa. In such a case, frequency hopping 1 can be applied to 0 (e.g., even or zero index) and the corresponding first repetition 915, and frequency hopping 2 can be applied to 1 (e.g., odd index) and the corresponding second and third repetitions 915. Similarly, frequency hopping 1 can be applied to 2 and 4, and frequency hopping 2 can be applied to 3.

[0241] Figure 10The figure illustrates an example of a process flow 1000 according to aspects of this disclosure. In some examples, process flow 1000 may implement or be implemented by aspects of wireless communication system 100 or 400. In some examples, process flow 1000 may additionally or alternatively implement or be implemented by aspects of bundling scheme 200, 300, 500, 600 or 700. For example, process flow 1000 may be implemented by base station 105-b and UE 115-b, which may represent references. Figure 1-7 Examples of base station 105 and UE 115 described herein. As described herein, UE 115-b may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) on one or more repeated sets transmitted to the uplink channel of base station 105-b.

[0242] In the following description of process flow 1000, operations may be performed in a different order than those shown, or operations performed by UE 115-b and base station 105-b may be performed in a different order or at a different time. For example, a particular operation may be omitted from process flow 1000, or other operations may be added to process flow 1000. Although UE 115-b and base station 105-b are shown as performing operations of process flow 1000, certain aspects of certain operations may also be performed by one or more other wireless devices.

[0243] At 1005, under certain circumstances, base station 105-b may send control signaling, such as RRC signaling, to UE 115-b. The control signaling may indicate a TDD (e.g., unpaired spectrum operation) TTI format pattern as described herein, or other TTI formats, which UE 115-b and base station 105-b may use for one or more downlink and / or uplink transmissions (e.g., repetition of uplink channel transmissions). The TDD TTI format pattern may indicate a pattern of one or more uplink TTIs, one or more downlink TTIs, one or more flexible TTIs, or any combination thereof, over multiple TTIs.

[0244] In some cases, control signaling can define a bundle size applicable to a set of multiple bundled intervals. As described herein, the bundle size can be defined for each bundled interval by the number of consecutive TTIs following the start time of the respective bundled interval. In some cases, control signaling can instruct a bundled interval configuration that indicates each bundled interval in the set of multiple bundled intervals includes at least one uplink TTI, at least one flexible TTI, or both. In some cases, control signaling can instruct a bundled interval configuration that indicates each bundled interval in the set of multiple bundled intervals includes at least one repeated uplink TTI, at least one flexible TTI, or both for uplink channels to satisfy one or more phase continuity conditions.

[0245] At 1010, base station 105-b may send multiple repeated control messages to UE 115-b configuring UE 115-b to transmit uplink channels (e.g., uplink channels such as PUSCH or PUCCH). In some cases, the control messages may indicate or define a bundle size as described herein. The control messages may indicate multiple numbers of repetitions, and in some cases, UE 115-b may use the indicated number of repetitions to determine the bundle size (e.g., based on an equation). In some cases, the control messages may include a value for a first frequency hopping and an indication of an offset, wherein a second frequency hopping may be based on the first frequency hopping and the offset. In some other cases, the control messages may include an indication of both the values ​​for the first and second frequency hopping.

[0246] At 1015, UE 115-b may transmit the first repetition of multiple repetitions of uplink channel transmission to base station 105-b in the first available TTI of the first bundled interval in the set of bundled intervals. In some cases, the start time of the first bundled interval may be the first TTI available for transmission of uplink channel repetitions or the first TTI available for transmission of uplink channel repetitions satisfying one or more phase continuity conditions. In some cases, the TDD TTI format style may indicate that the start time of the first bundled interval is a flexible TTI available for use as an uplink TTI. UE 115-b may transmit the first repetition at a first frequency hopping (e.g., a first frequency location or resource, such as an RB) in the set of multiple frequency hopping. In some cases, the first frequency hopping may correspond to a first index of the first bundled interval or the first transmission timing as described herein.

[0247] At 1020, in certain situations, UE 115-b may transmit a third repetition of multiple repetitions transmitted via the uplink channel to base station 105-b. The third repetition may be transmitted within a first bundling interval and may have phase continuity with the first repetition, for example, based on transmission within the same bundling interval. In some cases, the third repetition may be transmitted with a first frequency hopping (e.g., based on an index of the first bundling interval or the first transmission timing, based on phase continuity with the first repetition, or both).

[0248] At 1025, UE 115-b can transmit the second repetition of a plurality of repetitions of uplink channel transmission to base station 105-b. In some cases, UE 115-b can transmit the second repetition within a first bundled interval. In some other cases, UE 115-b can transmit the second repetition within a first available TTI of a second bundled interval in the bundled interval set. As described herein, the start time of the second bundled interval can be the next TTI that occurs after the end of a previous bundled interval in the bundled interval set and is available for transmission of uplink channel repetitions, or it can be the next TTI that occurs after the end of a previous bundled interval in the bundled interval set and is available for transmission of repetitions of uplink channel repetitions that satisfy one or more phase continuity conditions. In some cases, the TDD TTI format style can indicate that the start time of the second bundled interval is a flexible TTI that can be used as an uplink TTI (e.g., an available TTI). UE 115-b can transmit the second repetition with a second frequency hopping (e.g., a second frequency location or resource, such as an RB) in the frequency hopping set.

[0249] In the first example, UE 115-b may transmit a second repetition at a second frequency hopping during a second bundling interval, wherein the second frequency hopping may correspond to a second index of the second bundling interval or the second transmission timing as described herein. The consecutive indexes of the bundling intervals may correspond to the bundling intervals having available (e.g., uplink or flexible) TTIs in the TDD TTI format pattern, or may correspond to each consecutive bundling interval (e.g., with or without available uplink TTIs).

[0250] In the second example, UE 115-b may transmit a second repetition at a second frequency hopping during a first bundling interval, wherein the second repetition may not have phase continuity with the first repetition. For example, UE 115-b may transmit a second repetition that does not have phase continuity with the first repetition based on one or more phase continuity rules not being met.

[0251] At 1030, in certain circumstances, UE 115-b may transmit a fourth repetition of multiple repetitions transmitted via the uplink channel to base station 105-b. The fourth transmission may be transmitted within a second bundling interval. In some cases, the fourth repetition may have phase continuity with the second repetition (e.g., based on transmission within the same bundling interval). In some cases, the fourth repetition may be transmitted with a second frequency hopping (e.g., based on an index of the second bundling interval or the second transmission timing). In some cases, the fourth repetition may be transmitted with a first frequency hopping (e.g., based on transmission following a previous repetition with a second frequency hopping and in a different bundling interval or transmission timing).

If implemented in code executed by a processor, the functionality of the communication manager 1120, receiver 1110, transmitter 1115, or various combinations or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., components configured or otherwise supported for performing the functions described in this disclosure).

[0258] In some examples, the communication manager 1120 may be configured to use or otherwise cooperate with the receiver 1110, the transmitter 1115, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 1120 may receive information from the receiver 1110, send information to the transmitter 1115, or be integrated with the receiver 1110, the transmitter 1115, or a combination of both to receive information, send information, or perform various other operations as described herein.

[0259] According to the examples disclosed herein, the communication manager 1120 may support wireless communication at the UE. For example, the communication manager 1120 may be configured or otherwise supported to support components for receiving from a base station control messages that configure the UE to transmit an uplink channel. The communication manager 1120 may be configured or otherwise supported to support components for transmitting a first repeat of a first available TTI of a first bundled interval in a set of bundled intervals. The communication manager 1120 may be configured or otherwise supported to transmit a second repeat of a second available TTI of a second bundled interval in a set of bundled intervals, each bundled interval in the set of bundled intervals having a corresponding start time corresponding to a corresponding start time of a corresponding available TTI that appears after the end of a corresponding previous bundled interval in the set of bundled intervals.

[0260] Additionally or alternatively, according to the examples disclosed herein, the communication manager 1120 may support wireless communication at the UE. For example, the communication manager 1120 may be configured or otherwise supported for receiving from a base station control messages configuring the UE to transmit an uplink channel of multiple repeating sets. The communication manager 1120 may be configured or otherwise supported for transmitting a first repeating set of multiple repeating sets of uplink channels in a first bundled interval of a set of multiple bundled intervals and at a first hopping frequency of a first hopping frequency of a set of multiple frequency hopping intervals, the first hopping frequency corresponding to a first index of the first bundled interval.

[0261] Additionally or alternatively, according to the examples disclosed herein, the communication manager 1120 may support wireless communication at the UE. For example, the communication manager 1120 may be configured or otherwise supported for receiving from a base station control messages configuring the UE to transmit an uplink channel of multiple repeating sets. The communication manager 1120 may be configured or otherwise supported for transmitting a first repeat of a first set of multiple repeating sets of uplink channels via a first transmission timing, in a first bundled interval of a set of multiple bundled intervals, and at a first hopping frequency of a set of multiple frequency hopping, based on a first transmission timing index of a first transmission timing.

[0263] The actions performed by the communication manager 1120, as well as other examples herein, can be implemented to achieve one or more potential advantages. For example, the communication manager 1120 can improve available battery power and communication quality at a wireless device (e.g., UE 115) by bundling uplink channel transmission repetitions and / or using frequency hopping for transmissions of one or more of the repetitions. Based on bundling uplink channel transmission repetitions and / or using frequency hopping for transmissions of one or more of the repetitions, the improvement in communication quality can lead to improved link performance and reduced overhead. Accordingly, the communication manager 1120 can save power and increase battery life at the wireless device (e.g., UE 115) by strategically improving communication quality at the wireless device (e.g., UE 115).

[0264] Figure 12A block diagram 1200 of device 1205 according to an aspect of this disclosure is shown. Device 1205 may be an example of an aspect of device 1105 or UE 115 as described herein.

[0272] The processor of the wireless device (e.g., controls receiver 1210, transmitter 1215, or as referenced) Figure 14 The transceiver 1415 described can improve available battery power and communication quality. Compared to other systems and techniques (e.g., those that do not support repetition of bundled uplink channel transmissions and / or use frequency hopping for transmissions of one or more of the repetitions), the improved communication quality can increase available battery power and throughput (e.g., via reference). Figure 13 (The implementation of the described system components). Furthermore, the processor of the wireless device can identify one or more aspects of the repetitive bundling interval configuration used for transmitting uplink channel data, which can lead to improved communication quality, as well as power savings and increased battery life at the wireless device (e.g., supporting improved communication quality by strategically implementing bundling and / or frequency hopping).

[0273] Figure 13 A block diagram 1300 of a communication manager 1320 according to an aspect of this disclosure is shown. The communication manager 1320 may be an example of an aspect of the communication manager 1120, communication manager 1220, or both, as described herein. The communication manager 1320 or its various components may be examples of parts for performing various aspects of DMRS bundling and frequency hopping as described herein. For example, the communication manager 1320 may include a control receiving component 1325, an uplink channel transmitting component 1330, an uplink channel bundling component 1335, a bundling interval component 1340, a frequency hopping component 1345, or any combination thereof. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).

[0274] According to the examples disclosed herein, the communication manager 1320 may support wireless communication at the UE. The control receiving component 1325 may be configured or otherwise supported for receiving from the base station control messages configuring the UE to transmit an uplink channel of a plurality of repeating sets. The uplink channel transmitting component 1330 may be configured or otherwise supported for transmitting a first repeat of the plurality of repeating sets of uplink channels in a first available TTI of a first bundled interval in a plurality of bundled intervals. In some examples, the uplink channel transmitting component 1330 may be configured or otherwise supported for transmitting a second repeat of the plurality of repeating sets of uplink channels in a second available TTI of a second bundled interval in a plurality of bundled intervals, each bundled interval in the plurality of bundled intervals having a corresponding start time corresponding to a corresponding start time of a corresponding available uplink TTI appearing after the end of a corresponding previous bundled interval in the plurality of bundled intervals.

[0275] In some examples, the corresponding start time of a given available TTI is the start time of the next available TTI that occurs after the end of the previous bundled interval in a set of multiple bundled intervals.

[0276] In some examples, the control receiving component 1325 may be configured or otherwise supported for receiving RRC signaling or DCI indicating a TTI format configuration, wherein the corresponding available TTI for each bundled interval in a set of multiple bundled intervals is identified based on the TTI format configuration.

[0277] In some examples, each bundled interval in the set of multiple bundled intervals comprises multiple repeated transmissions of the uplink channel satisfying a phase continuity condition for two or more TTIs. In some examples, the phase continuity condition is satisfied based on the multiple repeated transmissions of the uplink channel having the same modulation order, the same frequency allocation, the same transmit power level, the same transmit beam, or any combination thereof.
