AI Technical Summary

Technical Problem

In 5G NR wireless communication systems, it is difficult for the UE to determine the RF retuning gap between the active uplink BWP and other uplink BWP, resulting in improper resizing and placing the RF retuning gap, increasing the number of punched symbols, discarded uplink transmissions, undecoded or corrupted uplink transmissions, and retransmissions.

Method used

The UE determines the RF retuning gap between the first uplink BWP and the second uplink BWP by determining the start and end symbols of the RF retuning gap of a specific size. The start symbol part is based on the second plurality of repeated start symbols and the number of symbols in the gap, and the end symbol part is based on the second plurality of repeated start symbols.

Benefits of technology

By determining a suitable RF retuning gap, the UE can perform cross-BWP uplink frequency hopping in wireless communications, reducing the number of punched symbols, discarded transmissions, undecoded or corrupted transmissions, and retransmissions due to improper RF retuning gap adjustment and placement.

Description

Technical Field

[0001]

[0004] Aspects of the present disclosure generally relate to wireless communications, and in particular, to techniques and apparatus for determining a radio frequency (RF) retuning gap for uplink frequency hopping across a bandwidth part (BWP). Background Art

[0002] Wireless communication systems are widely deployed to provide various 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-SCDMA) systems, and long term evolution (LTE). 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).

[0003] A wireless communication network may include multiple base stations (BSs) that can support communications for multiple user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, while 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, etc.

[0004] 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 city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectrum 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 referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0005] In some aspects, a method of wireless communication performed by a user equipment (UE) may include: determining a start symbol of a radio frequency (RF) retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop, wherein the start symbol of the RF retuning gap is based at least in part on a start symbol of the second plurality of repetitions and a number of symbols included in the RF retuning gap; determining an end symbol of the RF retuning gap based at least in part on the start symbol of the second plurality of repetitions; and performing RF retuning during the RF retuning gap.

[0006] In some aspects, a UE for wireless communication may include a memory and one or more processors coupled to the memory. For example, the one or more processors may be coupled to the memory operatively, electronically, communicatively, or otherwise. The memory may include instructions executable by the one or more processors (e.g., directly, after compilation, after conversion, etc.) to cause the UE to perform the following operations: determine a start symbol of an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first hop frequency and a second plurality of repetitions of the uplink transmission in a second hop frequency, wherein the start symbol of the RF retuning gap is based at least in part on a start symbol of the second plurality of repetitions and a number of symbols included in the RF retuning gap; determine an end symbol of the RF retuning gap based at least in part on the start symbol of the second plurality of repetitions; and perform RF retuning during the RF retuning gap.

[0007] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of a UE, the one or more instructions may cause the UE to: determine a start symbol of an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop, wherein the start symbol of the RF retuning gap is based at least in part on a start symbol of the second plurality of repetitions and a number of symbols included in the RF retuning gap; determine an end symbol of the RF retuning gap based at least in part on the start symbol of the second plurality of repetitions; and perform RF retuning during the RF retuning gap.

[0008] In some aspects, an apparatus for wireless communication may include: means for determining a start symbol for an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop, wherein the start symbol of the RF retuning gap is based at least in part on a start symbol of the second plurality of repetitions and a number of symbols included in the RF retuning gap; means for determining an end symbol of the RF retuning gap based at least in part on the start symbol of the second plurality of repetitions; and means for performing RF retuning during the RF retuning gap.

[0009] In summary, various aspects include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and / or processing systems as fully described herein with reference to and as illustrated by the accompanying drawings and description.

[0016] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough 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 understood 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 the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0017] 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 may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0018] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later (including NR technology).

[0019] Figure 11 is a diagram showing a wireless network 100 in which various aspects of the present disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include multiple BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific 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.

[0020] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by 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 1 In the example shown in , 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.

[0021] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport networks).

[0022] The wireless network 100 may also include a relay station. A relay station is an entity that receives data transmissions from an upstream station (e.g., a BS or a UE) and sends data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0023] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., 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).

[0024] A 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, for example, via a wireless or wired backhaul.

[0025] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio unit), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0026] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. 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 a connection to a network, for example, 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 inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0027] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can 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 can be deployed.

[0028] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). 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, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0029] As noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0030] Figure 2 Base station 110 and UE 120 (which may be Figure 11. Block diagram of a design 200 of a base station 110 and a UE 120. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0031] 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 the UE based at least in part on the MCS selected for each 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), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), 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)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The 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 (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using position coding to transmit additional information.

[0032] At UE 120, antennas 252a to 252r may receive downlink signals from 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, etc.) to obtain received symbols. 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. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0033] 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, CQI, etc.). 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, CP-OFDM, etc.), and transmitted to the base station 110. 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 decoded data to a data sink 239 and provide decoded control information to a 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 network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0034] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components in the base station 110 may perform one or more techniques associated with determining a radio frequency (RF) retuning gap for uplink frequency hopping across a bandwidth part (BWP), as described in greater detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct e.g. Figure 8 The operations of process 800 and / or other processes as 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 for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 8 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0035] In some aspects, the UE 120 may include: means for determining a start symbol of an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop, wherein the start symbol of the RF retuning gap is based at least in part on the start symbol of the second plurality of repetitions and the number of symbols included in the RF retuning gap; means for determining an end symbol of the RF retuning gap based at least in part on the start symbol of the second plurality of repetitions; and means for performing RF retuning during the RF retuning gap; etc. In some aspects, such means may include means for 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.

[0036] As noted above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0037] Many devices such as smart wearables, industrial sensors, and video surveillance equipment can use NR-light. NR-light works within the framework of 5G NR, but compared to NR, it has reduced transmit power, reduced bandwidth, reduced computational complexity, longer battery life, and / or a reduced number of transmit and receive antennas. For example, compared to NR premium UE, NR-light UE can use a bandwidth of 5MHz–20MHz in NR frequency range 1 (FR1, which may include sub-6GHz operating frequencies), where NR premium UE can use a bandwidth of 50MHz for a subcarrier spacing (SCS) of 15kHz, or a bandwidth of 100MHz for a subcarrier spacing of 30 / 60kHz. In some aspects, the network design takes into account the coexistence of NR premium UE and NR-light UE.

[0038] An NR-light UE may be a UE with reduced capabilities. A UE with reduced capabilities may be a device with reduced or lower capabilities relative to other UEs. For example, a UE with reduced capabilities may be equipped with fewer transmit and / or receive antennas, may be equipped with a lower battery, may be equipped with fewer processing and / or memory resources (which may result in a longer processing timeline), may only be able to monitor and / or process a reduced frequency bandwidth, may only be able to perform half-duplex frequency division duplexing, etc. In some cases, a UE with reduced capabilities may have reduced capabilities due to a small form factor, due to lower costs of maintaining a UE with reduced capabilities, etc. Examples of UEs with reduced capabilities may include IoT devices, biometric sensors / devices, smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry, vehicle components or sensors (e.g., cellular on-board diagnostics (OBD) devices), smart meters / sensors, etc.

[0039] In an NR-light deployment, a UE (e.g., an NR-light UE or a reduced capability UE) may be configured with one or more uplink BWPs (e.g., up to four uplink BWPs) and / or one or more downlink BWPs (e.g., up to four downlink BWPs). A BWP may be a contiguous set of physical resource blocks (PRBs) on a frequency carrier. A BWP allows a UE to transmit or receive with a narrower bandwidth than the entire cell or carrier bandwidth configured for the UE (e.g., configured for an access link on which the UE communicates with the BS). In some cases, the maximum BWP bandwidth (or maximum channel bandwidth) supported by the UE may be based at least in part on the UE capabilities of the UE. In the case of an NR-light UE, the UE may only support a smaller or narrower BWP. A narrow bandwidth BWP may allow power savings to be achieved for the UE due to the ability to operate the RF baseband components of the UE at a lower sampling rate and lower baseband processing.

[0040] In some cases, for a UE, one uplink BWP and one downlink BWP may be active at any given time. In these cases, the UE may not be allowed to send uplink transmissions outside the active uplink BWP. However, if the UE is an NR-light UE, the UE may not be able to perform frequency hopping for uplink transmit diversity in the active uplink BWP if the active uplink BWP is a narrow bandwidth uplink BWP that does not have enough bandwidth to support frequency hopping. Frequency hopping refers to a transmission technique in which a device sends repetitions of the same transmission or communication across different frequencies (e.g., one or more first repetitions at a first frequency and one or more second repetitions at a second frequency). The ability to perform frequency hopping for transmission increases the transmit diversity for transmission (e.g., because different frequencies may experience different channel conditions), which in turn improves the reliability and performance of the transmission. Therefore, if the UE cannot perform frequency hopping for uplink transmission, the UE cannot achieve the benefits of uplink diversity for uplink transmission.

[0041] One technique to overcome the narrow bandwidth of an active uplink BWP for frequency hopping may be referred to as cross-BWP uplink frequency hopping. In this case, the UE is allowed to send a first set of repetitions of uplink transmissions in an active uplink BWP, perform an RF switch to switch from the active uplink BWP to another uplink BWP configured for the UE, and send a second set of repetitions of uplink transmissions in the other uplink BWP. However, some wireless networks (e.g., 5G NR wireless networks) may support multiple subcarrier spacings (e.g., 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, etc.), may support flexible time domain resource allocation (e.g., by allowing a variable number of symbols to be allocated to a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission, etc.), and / or may support other parameters that may make it difficult for the UE to determine the size, start symbol, and / or end symbol of an RF retuning gap in which the UE will perform RF retuning between the active uplink BWP and the other uplink BWPs. This may result in an increased number of punctured symbols due to improper sizing and / or placement of RF retuning gaps, which may result in an increased number of dropped uplink transmissions, an increased number of undecodable or corrupted uplink transmissions, an increased number of retransmissions, etc.

[0042] Some aspects described herein provide techniques and apparatus for determining an RF retuning gap for uplink frequency hopping across a fork BWP. In some aspects, a UE (e.g., an NR-light UE or a UE with reduced capability) may determine an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first uplink BWP and a second plurality of repetitions of the uplink transmission in a second BWP by determining a start symbol and an end symbol of the RF retuning gap of a particular size (e.g., number of symbols). The UE may determine the start gap based at least in part on the start symbol of the second plurality of repetitions and the number of symbols included in the RF retuning gap, and may determine the end symbol based at least in part on the start symbol of the second plurality of repetitions.

[0043] Thus, in a scenario when the UE performs cross-BWP uplink frequency hopping in wireless communication, the UE is able to determine an RF retuning gap, wherein flexible communication parameters (e.g., flexible subcarrier spacing, flexible time domain resource allocation, etc.) may be configured. This allows the UE to perform RF retuning during the RF retuning gap in a manner that reduces the number of punctured symbols due to improper sizing and / or placement of the RF retuning gap, which reduces the number of discarded uplink transmissions, reduces the number of undecodable or corrupted uplink transmissions, reduces the number of retransmissions, etc.

[0044] Figures 3A-3E is a diagram illustrating one or more examples 300 of determining an RF retuning gap for uplink frequency hopping across a BWP in accordance with various aspects of the present disclosure. Figures 3A-3E As shown, example 300 may include a UE (e.g., UE 120). In some aspects, the UE may be included in a wireless network such as wireless network 100. In some aspects, the UE may communicate with a BS (e.g., BS 110) in the wireless network via a wireless access link. The wireless access link may include an uplink and a downlink. The UE may perform uplink transmissions on the uplink and may receive downlink transmissions on the downlink.

[0045] In some aspects, the wireless network may be a 5G NR wireless network or another type of wireless network that supports splitting, segmenting, or otherwise dividing the bandwidth of a wireless access link into BWPs. In this case, the UE may be configured with one or more BWPs for the uplink and / or one or more BWPs for the downlink. Figures 3A-3E As shown, in some aspects, a UE can be configured with multiple BWPs for uplink, such as bandwidth part 1 (BWP 1) and bandwidth part 2 (BWP 2). Figures 3A-3E In the illustrated example 300, BWP 1 may be referred to as an active uplink BWP for the UE, while BWP 2 may be referred to as an inactive uplink BWP, a supplemental uplink BWP, or another uplink BWP.

[0046] In some aspects, the UE may perform uplink frequency hopping across BWP 1 and BWP 2. Figures 3A-3E As shown, the UE can send one or more first repetitions (e.g., repetition 1 to repetition X) of the uplink transmission in a first hopping frequency (hopping frequency 1), and send one or more second repetitions (e.g., repetition 1 to repetition Y) of the uplink transmission in a second hopping frequency (hopping frequency 2). In this case, the UE can send one repetition per time slot, can send multiple repetitions per time slot, can send a portion of a repetition in a time slot, can send repetitions across multiple time slots, and so on.

[0047] In some aspects, the UE may be configured (e.g., via signaling from the BS, via hardware and / or software configuration, etc.) to perform various uplink frequency hopping patterns. Figure 3AAn example uplink frequency hopping pattern is shown, in which the UE is configured to send one or more first repetitions of hopping frequency 1 in BWP 1 (e.g., the UE's active uplink BWP), and then send one or more second repetitions of hopping frequency 2 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE). As another example, Figure 3B An example uplink frequency hopping pattern is shown in which the UE is configured to send one or more first repetitions of frequency hopping 1 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE) and subsequently send one or more second repetitions of frequency hopping 2 in BWP 1 (e.g., the UE's active uplink BWP).

[0048] In addition, the UE can perform RF retuning before frequency hop 1, between frequency hop 1 and frequency hop 2, and / or after frequency hop 2. Thus, the UE can retune one or more RF components of the UE (e.g., one or more antennas 252, one or more MODs 254, one or more Tx MIMO processors 266, one or more transmit processors 264, one or more transmit RF chain components, etc.) from the frequency of BWP 1 to the frequency of BWP 2, and / or from the frequency of BWP 2 to the frequency of BWP 1. In some aspects, the amount of time it takes the UE to perform the RF retuning can be based at least in part on the UE's ability to retune the one or more RF components of the UE.

[0049] To accommodate RF retuning, the UE may determine an RF retuning gap in which the UE will perform RF retuning. The size or duration of the RF retuning gap may be configured or determined such that the RF retuning gap is long enough to allow the UE to perform RF retuning during the RF retuning gap. In this case, the size or duration of the RF retuning gap may be based at least in part on the UE's ability to retune one or more RF components of the UE.

[0050] Figure 3C-3E One or more examples of determining an RF retuning gap during a transmit gap (Tx gap) between one or more first repetitions of frequency hop 1 and one or more second repetitions of frequency hop 2 are shown. Figure 3C-3E One or more examples in the context of an uplink frequency hopping pattern are shown, wherein the UE is configured to transmit one or more first repetitions of hopping frequency 1 in BWP 1 (e.g., the UE's active uplink BWP) and subsequently transmit one or more second repetitions of hopping frequency 2 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE), but in combination Figure 3C-3EOne or more of the described examples may be applied in the context of an uplink frequency hopping pattern, wherein the UE is configured to send one or more first repetitions of frequency hopping 1 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE) and subsequently send one or more second repetitions of frequency hopping 2 in BWP 1 (e.g., the UE's active uplink BWP).

[0051] like Figure 3C And as indicated by reference numeral 302, the UE may determine a starting symbol for the RF retuning gap. In some aspects, the UE may determine the starting symbol for the RF retuning gap based at least in part on a starting symbol of the one or more second repetitions (e.g., a starting symbol of repetition 1 in the one or more second repetitions) and a number of symbols included in the RF retuning gap (e.g., a size of the RF retuning gap). For example, the UE may determine the starting symbol to be n 2ndHopStart -N retuning , where n 2ndHopStart is the first symbol of frequency hopping 2 (for example, the starting symbol of repetition 1 in frequency hopping 2), N retuning is the number of symbols included in the RF retuning gap.

[0052] like Figure 3C As further shown by reference numeral 304, the UE may determine an end symbol of the RF retuning gap. In some aspects, the UE may determine an end symbol of the RF retuning gap based at least in part on a start symbol of one or more second repetitions of hop frequency 2 (e.g., a start symbol of repetition 1 in the one or more second repetitions). For example, the UE may determine the end symbol as n 2ndHopStart Thus, the end symbol of the RF retuning gap may be the adjacent symbol preceding the start symbol of repetition 1 in one or more second repetitions.

[0053] In some cases, due to the size or duration of the RF retuning gap, the start symbol of the RF retuning gap may occur during a repetition in one or more of the first repetitions in hop 1. For example, Figure 3C As shown, the start symbol of the RF retuning gap may occur during repetition X. The UE may determine, based at least in part on determining that the size or duration of the RF retuning gap is greater than the size or duration of the transmission gap between hop 1 and hop 2 (e.g., N retuning >N txgap , where N txgap is the number of symbols included in the transmission gap), to determine that the start symbol of the RF retuning gap may appear during a repetition in one or more first repetitions in frequency hopping 1.

[0054] In this case, the UE may determine that the RF retuning gap at least partially overlaps with at least a subset of the one or more first repetitions. Therefore, the UE may puncture or avoid transmitting symbols of at least the subset of the one or more first repetitions that overlap with the RF retuning gap. The symbols of at least the subset of the one or more first repetitions that overlap with the RF retuning gap may be referred to as Δ puncture UE can set Δ puncture Determined as Δ puncture =N retuning -N txgap . Δ puncture Can be located in time slot k hop -1, where k hop May refer to the first time slot of frequency hop 2 (eg, the time slot in which repetition 1 of the one or more second repetitions is transmitted).

[0055] like Figure 3D And shown by reference numeral 306, in some aspects, the UE may adjust the start symbol and the end symbol of the RF retuning gap. For example, in the case where the start symbol and the end symbol may cause puncturing or dropping of a specific type of uplink transmission in the repetition from hop frequency 1 that overlaps with the RF retuning gap, the UE may determine to adjust the start symbol and the end symbol of the RF retuning gap. In this case, the UE may determine to adjust the start symbol and the end symbol of the RF retuning gap based at least in part on determining that one or more symbols carrying a demodulation reference signal (DMRS) in hop frequency 1 overlap with the RF retuning gap. The UE may adjust the start symbol and the end symbol of the RF retuning gap by moving the start symbol and the end symbol forward in time so that the RF retuning gap begins to overlap at least partially with repetition 1 of hop frequency 2. The UE may continue to move the start symbol and the end symbol forward in time until the one or more symbols carrying the DMRS in hop frequency 1 do not overlap with the RF retuning gap.

[0056] In order to adjust the start symbol and end symbol of the RF retuning gap, the UE can puncture Determined as Δ puncture =Δ1+Δ2, where Δ1 is the number of symbols to be punctured or dropped from frequency hopping 1, and Δ2 is the number of symbols to be punctured or dropped from frequency hopping 2. The UE may initialize Δ1 to Δ1=Δ puncture, and Δ2 may be initialized to Δ2=0. If the UE determines that the value of Δ1 causes a symbol carrying a specific type of uplink transmission (e.g., DMRS) in hop frequency 1 to overlap with the RF retuning gap, the UE may adjust the values ​​of Δ1 and Δ2 m times (m=1, 2, ...) by Δ1=Δ1-1 and Δ2=Δ2+1, respectively, until the UE determines the value of m as follows: the value of m causes the symbol carrying the specific type of uplink transmission in hop frequency 1 to no longer overlap with the RF retuning gap. Therefore, the start symbol of the RF retuning gap and the end symbol of the RF retuning gap become n respectively. 2ndHopStart -N retuning +m and n 2ndHopStart -1+m.

[0057] like Figure 3E Also shown by reference numeral 308, the UE may perform RF retuning during the RF retuning gap (e.g., an unadjusted or adjusted RF retuning gap). For example, the UE may retun one or more RF components of the UE from being tuned to the frequency of BWP 1 to the frequency of BWP 2 during the RF retuning gap. Furthermore, if the RF retuning gap overlaps with any symbol of the repetition of frequency hop 1 and / or any symbol of the repetition of frequency hop 2, the UE may puncture or avoid transmitting these symbols during the RF retuning gap.

[0058] As mentioned above, Figures 3A-3E is provided as one or more examples. Other examples may differ from Figures 3A-3E An example of description.

[0059] Figure 4A and 4B 4 is a diagram illustrating one or more examples 400 of determining an RF retuning gap for uplink frequency hopping across a BWP in accordance with various aspects of the present disclosure. Figure 4A and 4B As shown, example 400 may include a UE (e.g., UE 120). In some aspects, the UE may be included in a wireless network such as wireless network 100. In some aspects, the UE may communicate with a BS (e.g., BS 110) in the wireless network via a wireless access link. The wireless access link may include an uplink and a downlink. The UE may perform uplink transmissions on the uplink and may receive downlink transmissions on the downlink.

[0060] In some aspects, the wireless network may be a 5G NR wireless network or another type of wireless network that supports splitting, segmenting, or otherwise dividing the bandwidth of a wireless access link into BWPs. In this case, the UE may be configured with one or more BWPs for the uplink and / or one or more BWPs for the downlink. Figure 4A and 4B As shown, in some aspects, a UE can be configured with multiple BWPs for uplink, such as bandwidth part 1 (BWP 1) and bandwidth part 2 (BWP 2). Figure 4A and 4B In the illustrated example 400, BWP 1 may be referred to as an active uplink BWP for the UE, while BWP 2 may be referred to as an inactive uplink BWP, a supplemental uplink BWP, or another uplink BWP.

[0061] In some aspects, the UE may perform uplink frequency hopping across BWP 1 and BWP 2. Figure 4A and 4B As shown, the UE can send one or more first repetitions (e.g., repetition 1 to repetition X) of the uplink transmission in a first hopping frequency (hopping frequency 1), and send one or more second repetitions (e.g., repetition 1 to repetition Y) of the uplink transmission in a second hopping frequency (hopping frequency 2). In this case, the UE can send one repetition per time slot, can send multiple repetitions per time slot, can send a portion of a repetition in a time slot, can send repetitions across multiple time slots, and so on.

[0062] In some aspects, the UE may be configured (e.g., via signaling from a BS, via hardware and / or software configuration, etc.) to perform various uplink frequency hopping patterns. For example, example 400 includes an example uplink frequency hopping pattern in which the UE is configured to send one or more first repetitions of hopping frequency 1 in BWP 1 (e.g., the UE's active uplink BWP) and subsequently send one or more second repetitions of hopping frequency 2 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE).

[0063] In some aspects, the UE can perform RF retuning after frequency hop 2, such as in conjunction with Figure 4A and 4B In some aspects, the UE may additionally perform RF retuning between frequency hopping 1 and frequency hopping 2, as described above in conjunction with Figures 3A-3E Thus, the UE is able to re-tune one or more RF components of the UE (e.g., one or more antennas 252, one or more MODs 254, one or more Tx MIMO processors 266, one or more transmit processors 264, one or more transmit RF chain components, etc.) from the frequency of BWP 1 to the frequency of BWP 2, and / or from the frequency of BWP 2 to the frequency of BWP 1.

[0064] To accommodate RF retuning, the UE may determine an RF retuning gap in which the UE is to perform RF retuning. The size or duration of the RF retuning gap may be configured or determined such that the RF retuning gap is long enough to allow the UE to perform RF retuning during the RF retuning gap. In this case, the size or duration of the RF retuning gap may be based at least in part on the UE's ability to retune one or more RF components of the UE.

[0065] like Figure 4A As indicated by reference numeral 402, the UE may determine a start symbol of the RF retuning gap after hop 2. In some aspects, the UE may determine the start symbol of the RF retuning gap based at least in part on an end symbol of one or more second repetitions (e.g., an end symbol of repetition Y in the one or more second repetitions). For example, the UE may determine the start symbol as n end +1, where n end is the end symbol of one or more second repetitions of frequency hop 2 (eg, the end symbol of repetition Y). Therefore, the start symbol of the RF retuning gap may be the adjacent symbol after the end symbol of repetition Y.

[0066] like Figure 4A As further indicated by reference numeral 404, the UE may determine an end symbol of the RF retuning gap. In some aspects, the UE may determine an end symbol of the RF retuning gap based at least in part on an end symbol of one or more second repetitions (e.g., an end symbol of repetition Y) and a number of symbols included in the RF retuning gap (e.g., a size of the RF retuning gap). For example, the UE may determine the end symbol to be n end +N retuning , where N retuning is the number of symbols included in the RF retuning gap.

[0067] In some aspects, the UE may limit the RF retuning gap to the time slot in which the last repetition (e.g., repetition Y) of the one or more second repetitions is to be sent. In this case, the RF retuning gap will be contained in the time slot, and the UE may determine the end slot of the RF retuning gap as the last symbol in the time slot, and determine the start symbol of the RF retuning gap as the number of symbols included in the RF retuning gap from the last symbol back. In some cases, limiting the RF retuning gap to the time slot in which the last repetition of the one or more second repetitions is to be sent may cause one or more symbols of the last repetition to be punctured or dropped. To determine whether the one or more symbols of the last repetition are to be punctured or dropped, the UE may determine the number of symbols N between the end symbol of the last repetition and the end of the time slot. remainThe UE may determine whether the number of symbols between the last repeated end symbol and the end of the slot is less than the number of symbols included in the RF retuning gap (eg, N remain <N retuning If the UE determines that the number of symbols between the last repeated end symbol and the end of the slot is less than the number of symbols included in the RF retuning gap, the UE may increase N retuning -N remain symbols to be punched or to be avoided.

[0068] like Figure 4B As also shown by reference numeral 406, the UE may perform RF retuning during the RF retuning gap. For example, the UE may retun one or more RF components of the UE from being tuned to the frequency of BWP 2 to the frequency of BWP 1 during the RF retuning gap. Furthermore, if the RF retuning gap overlaps with any symbols of the repetition of frequency hop 2, the UE may puncture or avoid transmitting those symbols during the RF retuning gap.

[0069] As mentioned above, Figure 4A and 4B is provided as one or more examples. Other examples may differ from Figure 4A and 4B An example of description.

[0070] Figure 5A and 5B is a diagram illustrating one or more examples 500 of determining an RF retuning gap for uplink frequency hopping across a BWP in accordance with various aspects of the present disclosure. Figure 5A and 5B As shown, example 500 may include a UE (e.g., UE 120). In some aspects, the UE may be included in a wireless network such as wireless network 100. In some aspects, the UE may communicate with a BS (e.g., BS 110) in the wireless network via a wireless access link. The wireless access link may include an uplink and a downlink. The UE may perform uplink transmissions on the uplink and may receive downlink transmissions on the downlink.

[0071] In some aspects, the wireless network may be a 5G NR wireless network or another type of wireless network that supports splitting, segmenting, or otherwise dividing the bandwidth of a wireless access link into BWPs. In this case, the UE may be configured with one or more BWPs for the uplink and / or one or more BWPs for the downlink. Figure 5A and 5BAs shown, in some aspects, a UE can be configured with multiple BWPs for uplink, such as bandwidth part 1 (BWP 1) and bandwidth part 2 (BWP 2). Figure 5A and 5B In the illustrated example 500, BWP 1 may be referred to as an active uplink BWP for the UE, while BWP 2 may be referred to as an inactive uplink BWP, a supplemental uplink BWP, or another uplink BWP.

[0072] In some aspects, the UE may perform uplink frequency hopping across BWP 1 and BWP 2. Figure 5A and 5B As shown, the UE can send one or more first repetitions (e.g., repetition 1 to repetition X) of the uplink transmission in a first hopping frequency (hopping frequency 1), and send one or more second repetitions (e.g., repetition 1 to repetition Y) of the uplink transmission in a second hopping frequency (hopping frequency 2). In this case, the UE can send one repetition per time slot, can send multiple repetitions per time slot, can send a portion of a repetition in a time slot, can send repetitions across multiple time slots, and so on.

[0073] In some aspects, the UE may be configured (e.g., via signaling from a BS, via hardware and / or software configuration, etc.) to perform various uplink frequency hopping patterns. For example, example 500 includes an uplink frequency hopping pattern in which the UE is configured to send one or more first repetitions of hopping frequency 1 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE) and subsequently send one or more second repetitions of hopping frequency 2 in BWP 1 (e.g., the UE's active uplink BWP).

[0074] In some aspects, the UE can perform RF retuning before frequency hopping 1, such as in conjunction with Figure 5A and 5B In some aspects, the UE may additionally perform RF retuning between frequency hopping 1 and frequency hopping 2, as described above in conjunction with Figures 3A-3E Thus, the UE is able to re-tune one or more RF components of the UE (e.g., one or more antennas 252, one or more MODs 254, one or more Tx MIMO processors 266, one or more transmit processors 264, one or more transmit RF chain components, etc.) from the frequency of BWP 1 to the frequency of BWP 2, and / or from the frequency of BWP 2 to the frequency of BWP 1.

[0075] To accommodate RF retuning, the UE may determine an RF retuning gap in which the UE is to perform RF retuning. The size or duration of the RF retuning gap may be configured or determined such that the RF retuning gap is long enough to allow the UE to perform RF retuning during the RF retuning gap. In this case, the size or duration of the RF retuning gap may be based at least in part on the UE's ability to retune one or more RF components of the UE.

[0076] like Figure 5A As indicated by reference numeral 502, the UE may determine a starting symbol of the RF retuning gap before frequency hop 1. In some aspects, the UE may determine the starting symbol of the RF retuning gap based at least in part on a starting symbol of one or more first repetitions (e.g., a starting symbol of repetition 1 in the one or more first repetitions) and a number of symbols included in the RF retuning gap. For example, the UE may determine the starting symbol to be n start -N retuning , where n start is the starting symbol of one or more first repetitions of frequency hopping 1 (eg, the starting symbol of repetition 1), N retuning is the number of symbols included in the RF retuning gap.

[0077] like Figure 5A As further shown by reference numeral 504, the UE may determine an end symbol of the RF retuning gap. In some aspects, the UE may determine an end symbol of the RF retuning gap based at least in part on a start symbol of one or more first repetitions (e.g., a start symbol of repetition 1). For example, the UE may determine the end symbol as n start Thus, the start symbol of the RF retuning gap may be the adjacent symbol preceding the start symbol of repetition 1 in the one or more first repetitions.

[0078] like Figure 5B As shown by reference numeral 506, the UE may perform RF retuning during the RF retuning gap. For example, the UE may retune one or more RF components of the UE from being tuned to the frequency of BWP 1 to the frequency of BWP 2 during the RF retuning gap.

[0079] As mentioned above, Figure 5A and 5B is provided as one or more examples. Other examples may differ from Figure 5A and 5B The content of the description.

[0080] Fig. 6A and 6B6 is a diagram illustrating one or more examples 600 of determining an RF retuning gap for uplink frequency hopping across a BWP in accordance with various aspects of the present disclosure. Fig. 6A and 6B As shown, example 600 may include a UE (e.g., UE 120). In some aspects, the UE may be included in a wireless network such as wireless network 100. In some aspects, the UE may communicate with a BS (e.g., BS 110) in the wireless network via a wireless access link. The wireless access link may include an uplink and a downlink. The UE may perform uplink transmissions on the uplink and may receive downlink transmissions on the downlink.

[0081] In some aspects, the wireless network may be a 5G NR wireless network or another type of wireless network that supports splitting, segmenting, or otherwise dividing the bandwidth of a wireless access link into BWPs. In this case, the UE may be configured with one or more BWPs for the uplink and / or one or more BWPs for the downlink. Fig. 6A and 6B As shown, in some aspects, a UE can be configured with multiple BWPs for uplink, such as bandwidth part 1 (BWP 1) and bandwidth part 2 (BWP 2). Fig. 6A and 6B In the illustrated example 600, BWP 1 may be referred to as an active uplink BWP for the UE, while BWP 2 may be referred to as an inactive uplink BWP, a supplemental uplink BWP, or another uplink BWP.

[0082] In some aspects, the UE can perform uplink frequency hopping across BWP 1 and BWP 2. For example, the UE can send one or more first repetitions of a PUSCH transmission in a first hop frequency (hop frequency 1) and send one or more second repetitions of a PUSCH transmission in a second hop frequency (hop frequency 2). As another example, the UE can send one or more first repetitions of a PUCCH transmission in a first hop frequency (hop frequency 1) and send one or more second repetitions of a PUCCH transmission in a second hop frequency (hop frequency 2). In this case, the UE can send one repetition per slot, can send multiple repetitions per slot, can send a portion of a repetition in a slot, can send a repetition across multiple slots, and so on.

[0083] In some aspects, the UE may be configured (e.g., via signaling from the BS, via hardware and / or software configuration, etc.) to perform various uplink frequency hopping patterns. Fig. 6A and 6BAn example uplink frequency hopping pattern is shown in which the UE is configured to send one or more first repetitions of hopping frequency 1 in BWP 1 (e.g., the UE's active uplink BWP) and subsequently send one or more second repetitions of hopping frequency 2 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE). However, Fig. 6A and 6B The example 600 shown in can be applied to other uplink frequency hopping patterns, for example, an uplink frequency hopping pattern in which the UE is configured to send one or more first repetitions of frequency hopping 1 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE), and subsequently send one or more second repetitions of frequency hopping 2 in BWP 1 (e.g., the UE's active uplink BWP).

[0084] In addition, the UE can use the above combined Figures 3A-3E The one or more techniques described perform RF retuning between frequency hop 1 and frequency hop 2. Thus, the UE is able to retune one or more RF components of the UE (e.g., one or more antennas 252, one or more MODs 254, one or more Tx MIMO processors 266, one or more transmit processors 264, one or more transmit RF chain components, etc.) from the frequency of BWP 1 to the frequency of BWP 2, and / or from the frequency of BWP 2 to the frequency of BWP 1. In some aspects, the amount of time it takes the UE to perform the RF retuning may be based at least in part on the UE's ability to retune the one or more RF components of the UE.

[0085] To accommodate RF retuning, the UE may determine an RF retuning gap in which the UE is to perform RF retuning. The size or duration of the RF retuning gap may be configured or determined such that the RF retuning gap is long enough to allow the UE to perform RF retuning during the RF retuning gap. In this case, the size or duration of the RF retuning gap may be based at least in part on the UE's ability to retune one or more RF components of the UE.

[0086] In some cases, the RF retuning gap may at least partially overlap with other uplink transmissions configured for the UE (e.g., uplink transmissions other than uplink transmissions to be sent using uplink frequency hopping). Thus, the UE can determine how to handle uplink transmissions that at least partially overlap with the RF retuning gap.

[0087] like Fig. 6AAnd illustrated by reference numeral 602, in some aspects, the UE may determine that an RF retuning gap between one or more first repetitions of a PUSCH transmission and one or more second repetitions of the PUSCH transmission at least partially overlaps with a PUCCH transmission. The PUCCH transmission may carry uplink control information (UCI), such as hybrid automatic repeat request (HARQ) feedback, channel state information (CSI) feedback, and / or other types of UCI. In some aspects, the PUCCH transmission may be a single-slot PUCCH transmission included in the same slot as the repetition of the PUSCH transmission in hop 2.

[0088] like Fig. 6A As further shown by reference numeral 604, the UE may multiplex the UCI for the PUCCH transmission into a repetition in one or more second repetitions. In this case, the UE may multiplex the UCI for the PUCCH transmission into a repetition included in the same timeslot as the PUCCH transmission. Multiplexing the UCI for the PUCCH transmission into the repetition for the PUSCH transmission may be referred to as UCI on PUSCH, UCI piggybacking, or other terminology.

[0089] like Figure 6B As shown by reference numeral 606, in some aspects, the UE may determine that an RF retuning gap between one or more first repetitions of a first PUCCH transmission (PUCCH 1) and one or more second repetitions of PUCCH 1 at least partially overlaps with another PUCCH transmission (PUCCH 2). PUCCH 1 and PUCCH 2 may each carry UCI.

[0090] like Figure 6BAs further shown by reference numeral 608, the UE may send a repetition of PUCCH 2 or PUCCH 1 in the same time slot as PUCCH 2, and may discard or avoid sending another uplink transmission based at least in part on the corresponding priorities associated with PUCCH 2 and the repetition of PUCCH 1. In some aspects, the corresponding priorities associated with PUCCH 2 and the repetition of PUCCH 1 may be based at least in part on the type of UCI carried by PUCCH 2 and the repetition of PUCCH 1. For example, HARQ feedback may be the highest priority, scheduling request (SR) may be the second highest priority, and CSI report may be the third highest priority. Other UCI type hierarchies may be used. In addition, if both PUCCH 2 and the repetition of PUCCH 1 include CSI report UCI, different types of CSI reports may be configured in the priority hierarchy. In some aspects, the UE may send a PUCCH transmission with the highest priority UCI type, and may discard or avoid sending other PUCCH transmissions.

[0091] In some aspects, the respective priorities associated with PUCCH 2 and repetitions of PUCCH 1 may be based at least in part on the respective starting slot indices of PUCCH 2 and repetitions of PUCCH 1. In this case, the UE may send the PUCCH transmission with the earliest or lowest starting slot index and may drop or avoid sending other PUCCH transmissions. In some aspects, the respective priorities associated with PUCCH 2 and repetitions of PUCCH 1 may be based at least in part on a combination of UCI type, starting slot index, and / or other parameters.

[0092] As shown above, Fig. 6A and 6B is provided as one or more examples. Other examples may differ from Fig. 6A and 6B An example of description.

[0093] Fig. 7A and 7B is a diagram illustrating one or more examples 700 of determining an RF retuning gap for uplink frequency hopping across a BWP in accordance with various aspects of the present disclosure. Fig. 7A and 7BAs shown, example 700 may include a UE (e.g., UE 120). In some aspects, the UE may be included in a wireless network such as wireless network 100. In some aspects, the UE may communicate with a BS (e.g., BS 110) in the wireless network via a wireless access link. The wireless access link may include an uplink and a downlink. The UE may perform uplink transmissions on the uplink and may receive downlink transmissions on the downlink.

[0094] In some aspects, the wireless network may be a 5G NR wireless network or another type of wireless network that supports splitting, segmenting, or otherwise dividing the bandwidth of a wireless access link into BWPs. In this case, the UE may be configured with one or more BWPs for the uplink and / or one or more BWPs for the downlink. Fig. 7A and 7B As shown, in some aspects, a UE can be configured with multiple BWPs for uplink, such as bandwidth part 1 (BWP 1) and bandwidth part 2 (BWP 2). Fig. 7A and 7B In the illustrated example 700, BWP 1 may be referred to as an active uplink BWP for the UE, while BWP 2 may be referred to as an inactive uplink BWP, a supplemental uplink BWP, or another uplink BWP.

[0095] In some aspects, the UE can perform uplink frequency hopping across BWP 1 and BWP 2. For example, the UE can send one or more first repetitions of a PUSCH transmission in a first hop frequency (hop frequency 1) and send one or more second repetitions of a PUSCH transmission in a second hop frequency (hop frequency 2). As another example, the UE can send one or more first repetitions of a PUCCH transmission in a first hop frequency (hop frequency 1) and send one or more second repetitions of a PUCCH transmission in a second hop frequency (hop frequency 2). In this case, the UE can send one repetition per slot, can send multiple repetitions per slot, can send a portion of a repetition in a slot, can send a repetition across multiple slots, and so on.

[0096] In some aspects, the UE may be configured (e.g., via signaling from the BS, via hardware and / or software configuration, etc.) to perform various uplink frequency hopping patterns. Fig. 7A and 7BAn example uplink frequency hopping pattern is shown in which the UE is configured to send one or more first repetitions of frequency hopping 1 in BWP 2 (e.g., outside the UE's active uplink BWP and in an inactive or supplemental uplink BWP of the UE) and subsequently send one or more second repetitions of frequency hopping 2 in BWP 1 (e.g., the UE's active uplink BWP).

[0097] In addition, the UE can use the above combined Figure 5A and 5B The one or more techniques described perform RF retuning prior to frequency hop 1. Thus, the UE is able to retune one or more RF components of the UE (e.g., one or more antennas 252, one or more MODs 254, one or more Tx MIMO processors 266, one or more transmit processors 264, one or more transmit RF chain components, etc.) from the frequency of BWP 1 to the frequency of BWP 2, and / or from the frequency of BWP 2 to the frequency of BWP 1. In some aspects, the amount of time it takes the UE to perform the RF retuning may be based at least in part on the UE's ability to retune the one or more RF components of the UE.

[0098] To accommodate RF retuning, the UE may determine an RF retuning gap in which the UE is to perform RF retuning. The size or duration of the RF retuning gap may be configured or determined such that the RF retuning gap is long enough to allow the UE to perform RF retuning during the RF retuning gap. In this case, the size or duration of the RF retuning gap may be based at least in part on the UE's ability to retune one or more RF components of the UE.

[0099] In some cases, the UE is able to use various techniques to determine the starting symbol of one or more first repetitions of hop 1 (e.g., the starting symbol of the first repetition (repetition 1) in the one or more first repetitions), where the various techniques are adapted to the RF retuning gap before the first hop, to various UE processing capabilities of the UE, etc.

[0100] like Fig. 7A As shown by reference numeral 702, in some aspects, the UE may determine a starting symbol for a first repetition of PUSCH transmission in hop 1. In some aspects, the UE may determine a starting symbol for a first repetition of PUSCH transmission in hop 1 to satisfy N2+N retuning (or N2 and N retuning The maximum allowed value of retuningis the number of symbols included in the RF retuning gap, and N2 is the PUSCH preparation time capability of the UE in symbols. In this case, the UE determines the starting symbol of the first repetition of PUSCH transmission in hop 1 so that the starting symbol appears at least N2+N after the end symbol of the physical downlink control channel (PDCCH) transmission carrying downlink control information (DCI) for scheduling PUSCH transmission. retuning In this way, sufficient time is provided to the UE to prepare for PUSCH transmission before performing RF retuning in the RF retuning gap.

[0101] In some aspects, if a PUSCH transmission is to carry a CSI report, the UE may determine the starting symbol for the first repetition of the PUSCH transmission in hop 1 to satisfy Z+N retuning (or Z and N retuning ), where Z is the CSI report preparation time capability of the UE (in symbols). In this case, the UE determines the starting symbol of the first repetition of PUSCH transmission in hop 1 so that the starting symbol occurs at least Z+N after the end symbol of the PDCCH transmission used to carry (e.g., periodically or semi-persistently) trigger CSI reporting. retuning symbols, and the start symbol appears at least Z+N after the end symbol of the associated CSI measurement resource (e.g., CSI reference signal (CSI-RS), CSI interference measurement (CSI-IM), etc.) retuning In this way, sufficient time is provided to the UE to prepare the CSI report before performing RF retuning in the RF retuning gap.

[0102] In some aspects, if the start time of a PUSCH transmission is specified by a timeslot, the UE may determine the start time of a PUSCH transmission based at least in part on a timeslot offset between a timeslot in which a PDCCH transmission carrying DCI for scheduling a PUSCH transmission is sent and a timeslot in which a first repetition of a PUSCH transmission in hop 1 is to be sent (e.g., Fig. 7A The UE may use a time slot offset (K2) as indicated in the RF retuning interval to determine the starting symbol of the first repetition of PUSCH transmission in frequency hop 1. In this case, the time slot offset may be configured (e.g., by the BS or another network entity) to meet a time slot number threshold (e.g., K2=4 or more time slots) based at least in part on the number of symbols included in the RF retuning interval, the PUSCH processing capability of the UE, and / or other parameters.

[0103] In some cases, the PUSCH transmission may be configured with an associated DMRS. The DMRS may be configured or scheduled via Type A DMRS mapping. In this case, the frontloaded DMRS may be mapped to the second or third symbol of the timeslot in which the first repetition of the PUSCH transmission is to be sent. In this case, if the UE does not have sufficient time between the PDCCH for scheduling the PUSCH transmission and the first repetition or between the CSI measurement resources and the first repetition, the UE may puncture or avoid sending one or more symbols before the frontloaded DMRS to ensure that the UE has sufficient time to perform RF retuning.

[0104] like Figure 7B As indicated by reference numeral 704, in some aspects, the UE may determine a starting symbol for a first repetition of a PUCCH transmission in hop 1. In some aspects, the PUCCH transmission may carry HARQ feedback (e.g., an acknowledgement (ACK) or a negative acknowledgement (NACK)) associated with a physical downlink shared channel (PDSCH) transmission scheduled by the PDCCH transmission. In some aspects, the UE may determine a starting symbol for a first repetition of a PUCCH transmission in hop 1 to satisfy N1+N retuning (or N1 and N retuning The maximum allowed value of retuning is the number of symbols included in the RF retuning gap, and N1 is the PDSCH processing time capability of the UE in symbols. In this case, the UE determines the starting symbol of the first repetition of the PUCCH transmission in hop 1 so that the starting symbol appears at least N1+N after the end symbol of the PDSCH transmission. retuning Symbols, where, for PDSCH transmission, the PUCCH transmission is to carry HARQ feedback. In this way, sufficient time is provided to the UE to process the PDSCH transmission and prepare the HARQ feedback before performing RF retuning in the RF retuning gap.

[0105] In some aspects, if the start time of the PUCCH transmission is specified by a time slot, the UE may determine the start time of the PUCCH transmission based at least in part on the time slot offset between the time slot in which the PDSCH transmission is completed and the time slot in which the first repetition of the PUCCH transmission in hop 1 is to be sent (e.g., Figure 7B The starting symbol of the first repetition of PUCCH transmission in hop 1 may be determined by using K1 indicated in RF retuning interval (K1=3 or more slots). In this case, the slot offset may be configured (e.g., by the BS or another network entity) to meet a slot number threshold (e.g., K1=3 or more slots) based at least in part on the number of symbols included in the RF retuning interval, the PDSCH processing capability of the UE, and / or other parameters.

[0106] As shown above, one or more examples are provided. Fig. 7A and 7B Other examples may differ from Fig. 7A and 7B An example of description.

For example, as described above, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may determine a start symbol of an RF retuning gap between a first plurality of repetitions of an uplink transmission in a first hop frequency and a second plurality of repetitions of an uplink transmission in a second hop frequency.
