[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 015,240, filed on April 24, 2020, entitled “UPLINK CONTROL CHANNEL TRANSMISSION IN HIGH BAND OPERATION,” and U.S. Non-Provisional Patent Application No. 17 / 237,753, filed on April 22, 2021, entitled “UPLINK CONTROL CHANNEL TRANSMISSION IN HIGH BAND OPERATION,” which are hereby expressly incorporated herein by reference. Technical Field
[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for uplink control channel transmissions in high-band operations. Background Art
[0004] Wireless communication systems are widely deployed to provide various types of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include: code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-CDMA) systems, and long term evolution (LTE) systems. LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).
[0005] A wireless network may include multiple base stations (BSs) that may support communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, and the like.
[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, or even global level. NR (also known as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), better integration with other open standards, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies are still useful. Summary of the invention

[0035] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be comprehensive and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is realized independently of any other aspect of the present disclosure or realized in combination with any other aspect of the present disclosure. For example, using any number of aspects set forth in this article, a device can be implemented or a method can be practiced. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth in this article or different from the various aspects of the present disclosure set forth in this article. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.
[0036] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0037] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).
[0038] Figure 1 1 is a schematic diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include a plurality of base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), and the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.
[0039] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.
[0040] In some aspects, the cells are not necessarily stationary, and the geographic area of the cells can move according to the location of the mobile BS. In some aspects, the BSs can be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections or virtual networks) using any suitable transport network.
[0041] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions of other UEs. Figure 1 In the example shown, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay station, and the like.
[0042] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).
[0043] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.
[0044] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. UEs may be cellular phones (e.g., smart phones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet computers, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices or devices, biometric sensors / devices, wearable devices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, or any other suitable device configured to communicate via wireless or wired media.
[0045] Some UEs may be considered as machine type communication (MTC) UEs or evolved or enhanced machine type (eMTC) communication UEs. MTC UEs and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or provide a connection to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0046] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0047] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol), and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described as being performed by base station 110 in other parts of this document.
[0048] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may span 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2), which may span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" and the like (if used herein) can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to these modified frequency ranges.
[0049] As mentioned above, providing Figure 1 As an example. Other examples may be different from the Figure 1 Examples described.
[0050] Figure 2is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.
[0051] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.
[0052] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, among other parameters. In some aspects, one or more components of UE 120 may be included in a housing.
[0053] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.
[0054] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, as well as other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmit and / or receive components (e.g. Figure 2 One or more antenna elements of one or more components).
[0055] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of one (or more) antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, such as those described in reference to Figure 3-Figure 8 As described.
[0056] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of one (or more) antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, such as those described in reference to Figure 3-Figure 8 As described.
[0057] The controller / processor 240 of the base station 110, the controller / controller 280 of the UE 120, and / or Figure 2 Any other components of the UE 120 may perform one or more techniques associated with uplink control channel transmission in high-band operation, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / controller 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The process 700 Figure 8 10 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), the one or more instructions may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 7 The process 700 Figure 8 The operations of process 800 and / or other processes described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0058] In some aspects, UE 120 may include: a unit for determining an increased bandwidth configuration for an ePUCCH based at least in part on an ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses a plurality of contiguous RBs for the ePUCCH; a unit for transmitting the ePUCCH using the increased bandwidth configuration; a unit for performing a frequency domain OCC operation on the plurality of contiguous RBs based at least in part on the increased bandwidth configuration; a unit for performing time domain orthogonal cover coding (OCC) on the plurality of contiguous RBs based at least in part on the increased bandwidth configuration, and the like. In some aspects, these units may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.
[0059] In some aspects, the base station 110 may include: means for determining an increased bandwidth configuration for an ePUCCH based at least in part on an ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses a plurality of contiguous RBs for the ePUCCH; means for receiving the ePUCCH using the increased bandwidth configuration, etc. In some aspects, these means may include combining Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.
[0060] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functions described above for each block may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0061] As mentioned above, providing Figure 2 As an example. Other examples may be different from the Figure 2 Examples described.
[0062] The Physical Uplink Control Channel (PUCCH) is a physical channel used by the UE to transmit control information. The PUCCH can be generated according to the format. Different formats of the PUCCH can be used to carry different types of information, can be used in different scenarios, and can be associated with different features. Baseline NR deployments (e.g., enhanced mobile broadband (eMBB)) can be associated with five PUCCH formats (e.g., PUCCH formats 0, 1, and 4 that can occupy one resource block (RB), and PUCCH formats 2 and 3 that can occupy a configurable number of resource blocks).
[0063] In the unlicensed frequency range 1 (FR1) band, an enhanced PUCCH (ePUCCH) format may be used. The ePUCCH formats may include ePUCCH formats 0, 1, 2, and 3 described below. A PUCCH using the ePUCCH format is referred to herein as ePUCCH. In some aspects, the ePUCCH may use an interleaved structure, which means that the RBs of the ePUCCH are interleaved across a set of resources. The use of an interleaved structure may increase the available power (e.g., to a maximum of 23 decibel milliwatts (dBm) per UE) while complying with a power spectral density (PSD) limit of 10 to 13 dBm per MHz. In some aspects, interleaving may disperse the RBs of the ePUCCH so that each RB may be transmitted at a higher power while remaining below the PSD limit.
[0064] In some aspects, for ePUCCH formats 0 and 1, different cyclic shifts may be used for different RBs in an interlace, and a cyclic shift step increase (e.g., to a step of 5) may be used for adjacent RBs in an interlace. In some aspects, for ePUCCH format 2, for user multiplexing, a frequency domain orthogonal cover coding (OCC) operation may be performed using an OCC length of 1, 2, or 4. In some aspects, the OCC may be circulated over the physical resource blocks (PRBs) of the interface to reduce the peak-to-average power ratio (PAPR) and cubic metric (CM) values. In some aspects, for ePUCCH format 3, user multiplexing of control data associated with the ePUCCH may be based at least in part on: a pre-discrete Fourier transform (pre-DFT) OCC with block-by-block repetition in the time domain, followed by mapping on the RBs on the interlace. User multiplexing for reference signals may be based at least in part on using different cyclic shifts of the same base sequence for all multiplexed users. An interleaved set of RBs may be referred to herein as a discontinuous set of RBs.
[0065] PUCCH in unlicensed bands (e.g., FR2) above FR1 may occupy a larger bandwidth than PUCCH in FR1. In some aspects, with a 120kHz subcarrier spacing (SCS), the total occupied bandwidth of PUCCH (referring to eMBB PUCCH) may be 1.44MHz for PUCCH formats 0, 1, and 4, and may be up to approximately 23MHz for PUCCH formats 2 and 3. As another example, with a 960kHz SCS, the total occupied bandwidth of PUCCH may be approximately 12MHz for PUCCH formats 0, 1, and 4, and may be up to approximately 184MHz for PUCCH formats 2 and 3. In higher frequency bands, there may be a PSD limit of 23dBm / MHz, and an effective isotropic radiated power (EIRP) of up to 40dBm. In some aspects, while a mobile terminal (e.g., UE) may operate at approximately 23dBm, some other user terminals (e.g., CPE) may operate at a higher EIRP, such as an EIRP limit of up to 40dBm. However, the wider bandwidth of the PUCCH in the higher frequency band may mean that interleaving, such as that specified by the ePUCCH format of unlicensed FR1, leads to suboptimal resource utilization.
[0066] Some techniques and apparatus described herein provide ePUCCH formats that use an increased bandwidth configuration for a higher frequency band (e.g., FR2) that uses a contiguous set of RBs (e.g., no interleaving). In some aspects, the ePUCCH in the higher frequency band can use a sufficiently wide bandwidth that interleaving provides little benefit at the expense of increased channel usage, and the maximum transmit power requirements of the higher frequency band can be achieved without using interleaving. An ePUCCH configuration that uses a contiguous set of RBs may be referred to as an increased bandwidth configuration. In conjunction with Figure 3-Figure 6 A specific example of an increased bandwidth configuration for an unlicensed higher frequency band is described. Thus, resource utilization, PUCCH transmission efficiency, and PAPR in an unlicensed higher frequency band (eg, FR2) are improved.
[0067] Figure 3is a schematic diagram of an example 300 of sending ePUCCH in a higher frequency band using an increased bandwidth configuration according to the present disclosure. As shown, example 300 includes UE 120 and BS 110. As indicated by reference numeral 310, UE 120 may be associated with a higher frequency band, such as FR2 or a frequency band higher than FR2. For example, UE 120 may be configured to communicate in a higher frequency band. As another example, UE 120 may be associated with a frequency higher than 6 GHz. In some aspects, UE 120 may be associated with an SCS of 120 kHz, 240 kHz, 960 kHz, 1.92 MHz, 3.84 MHz, and the like. In addition, the higher frequency band may be unlicensed, which means that UE 120 may access the higher frequency band using a channel access mechanism.
[0068] As indicated by reference numeral 320, UE 120 may determine an increased bandwidth configuration for an ePUCCH based at least in part on an ePUCCH format. For example, UE 120 may receive information indicating an ePUCCH format (e.g., configuration information, system information, etc.). In some aspects, the information indicating the ePUCCH format may indicate a maximum transmission bandwidth N_RB (in terms of resource blocks) and an ePUCCH format. In some aspects, UE 120 may use an ePUCCH format based at least in part on a higher frequency band being unlicensed. For example, UE 120 may determine that an operating band of UE 120 is a higher frequency band and is unlicensed, and therefore may determine to use an ePUCCH format. As another example, UE 120 may receive information indicating an ePUCCH format based at least in part on an unlicensed higher frequency band.
[0069] The increased bandwidth configuration may use a contiguous set of RBs for the ePUCCH. In some aspects, the increased bandwidth configuration may not use an interleaved waveform for the ePUCCH. As shown by reference numeral 330, the UE 120 may send the ePUCCH according to the ePUCCH format. In some aspects, the UE 120 may send the ePUCCH using the increased bandwidth configuration. In some aspects, the UE 120 may perform frequency domain and / or time domain OCC based at least in part on the ePUCCH format, such as in conjunction with Figure 4-6 As described in more detail, the resource efficiency of the ePUCCH can be improved while achieving maximum transmit power.
[0070] As mentioned above, providing Figure 3 As an example. Other examples may be different from the Figure 3 Examples described.
[0071] Figure 44 is a schematic diagram illustrating an example 400 of an increased bandwidth configuration for ePUCCH format 0 or format 1 in accordance with the present disclosure. The increased bandwidth configuration for ePUCCH format 0 or 1 may use a contiguous set of RBs. In some aspects, each RB may span more than 1 MHz, so an interleaved waveform may not be required to achieve acceptable transmit power. In addition, a contiguous set of aggregated RBs may achieve a lower PAPR than an interleaved waveform. Still further, the use of contiguous RBs may enable frequency hopping.
[0072] In some aspects, the increased bandwidth configuration for ePUCCH format 0 or 1 may use an increased sequence length (i.e., an extended sequence) relative to an existing PUCCH format defined in NR or an ePUCCH format that does not use the increased bandwidth configuration. For example, for ePUCCH format 0 or 1, a longer sequence with M RBs may be used, where M is the number of RBs included in the PUCCH resource. Thus, the length of the sequence may be equal to the total number of mapped REs of the PUCCH resource. In some aspects, the increased sequence length for enhanced PUCCH format 0 or 1 may allow an increased cyclic shift interval, and the increased cyclic shift interval may enable better user multiplexing with PUCCH format 0 or 1. In some aspects, different cyclic shifts may be used to indicate an acknowledgment (ACK), a negative acknowledgment (NACK), a scheduling request (SR), and the like. This may be particularly beneficial in frequency bands higher than FR1 or FR2 because the coherence bandwidth of the channel may be greater than the coherence bandwidth in FR1 or FR 2. Additionally or alternatively, an increased bandwidth configuration for ePUCCH format 0 or 1 may use a different cyclic shift on each RB spanned by the increased bandwidth, and the cyclic shift on each adjacent RB may be increased by a step size, where, for a default cyclic shift step size, a starting cyclic shift is configured and signaled for the first RB of ePUCCH format 0 or 1.
[0073] In some aspects, the ePUCCH may be divided into multiple RB groups, such as K RB groups. This is shown by reference numeral 410. An RB group may include one or more RBs. In this case, as shown, each RB group may use a cyclic shift value according to the cyclic shift step size. For example, the cyclic shift may circulate on the RB according to the cyclic shift step size. In some aspects, a first set of RB groups (e.g., 12 RB groups or different numbers of RB groups, depending on the cyclic shift and the number of RBs) may use a first root, while a second set of RB groups may use a second root. In some aspects, the cyclic shift step size may indicate a positive SR or a negative SR. In some aspects, the UE 120 may select different cyclic shift step sizes based at least in part on a positive SR or a negative SR. In some aspects, as shown, the ePUCCH may use repetition in the frequency domain. As further shown, the ePUCCH may use a sequence of length N for each RB group of the PUCCH resource. In some aspects, N may be equal to the number of mapped REs for each RB of the PUCCH resource. In some aspects, the sequence may be repeated in each RB group (eg, using a different cyclic shift X0...X k ).
[0074] Reference numeral 420 shows an example of an ePUCCH using a longer sequence than the example shown in reference numeral 410. In some aspects, the ePUCCH shown in reference numeral 420 can use a sequence that spans multiple RBs. For example, the sequence can span the ePUCCH (e.g., the length can be equal to the total number of mapped REs of the PUCCH resources of the ePUCCH). In this case, the ePUCCH can use the first root and the next ePUCCH can use the second root.
[0075] As mentioned above, providing Figure 4 As an example. Other examples may be different from the Figure 4 Examples described.
[0076] Figure 5is an example diagram illustrating an example 500 of an increased bandwidth configuration for ePUCCH format 2 in accordance with the present disclosure. In example 500, 2 RBs, each with 12 resource elements (REs), are code division multiplexed (CDM). In some aspects, the increased bandwidth configuration for ePUCCH format 2 may use frequency domain OCCs for multiple consecutive RBs. In some aspects, the frequency domain OCC may have a length greater than 4, such as 6, 8, 9, 12, 16, and so on. Here, the length of the frequency domain OCC is 8. Thus, multiple consecutive RBs may be multiplexed with frequency domain OCCs spanning multiple consecutive RBs. This may be particularly useful for a 120kHz SCS because the channel may be relatively flat in such an SCS, resulting in a PAPR improvement relative to other SCSs. It should be noted that any number of consecutive RBs may be multiplexed in this manner.
[0077] As mentioned above, providing Figure 5 As an example. Other examples may be different from the Figure 5 Examples described.
[0078] Figure 6 6M modulated signals [b0…b 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 6M-1 ] performs a block-by-block pre-DFT time-domain OCC operation. As further shown, the block-by-block pre-DFT time-domain OCC operation and DFT spreading cause UE0 and UE1 to use alternating tones, thereby reducing interference between UE0 and UE1. For example, UE0 uses a first tone, a third tone, and so on, as shown by the shading of the tones shown by reference numeral 610 in the UE0 schematic. In addition, UE1 uses a second tone, a fourth tone, and so on, as shown by the shading of the tones shown by reference numeral 620 in the UE1 diagram. In some aspects, example 600 may be applicable to ePUCCH format 3 or ePUCCH format 4.
[0079] As mentioned above, providing Figure 6 As an example. Other examples may be different from the Figure 6 Examples described.
[0080] Figure 77 is a diagram illustrating an example process 700 performed, for example, by a UE according to the present disclosure. Example process 700 is an example of a UE (eg, UE 120, etc.) performing operations associated with uplink control channel transmission in high-band operation.
[0081] like Figure 7 As shown, in some aspects, process 700 may include: receiving configuration information indicating an ePUCCH format for an enhanced physical uplink control channel (ePUCCH), wherein the ePUCCH is associated with an increased bandwidth configuration based at least in part on the ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses multiple consecutive RBs for the ePUCCH (block 710). In some aspects, the UE (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, etc.) may receive the configuration information, such as via radio resource control (RRC) signaling, medium access control (MAC) signaling, downlink control information (DCI), or a combination thereof. The configuration information may indicate an ePUCCH format for the ePUCCH. As described above, the ePUCCH format may be associated with an increased bandwidth configuration. In some aspects, the increased bandwidth configuration uses multiple consecutive RBs for the ePUCCH.
[0082] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include transmitting the ePUCCH using the increased bandwidth configuration (block 720). In some aspects, the UE (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, etc.) may transmit the ePUCCH using the increased bandwidth configuration, as described above.

Example process 800 is an example of a base station (eg, BS 110, etc.) performing operations associated with uplink control channel transmission in high-band operation.
