[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to Indian Patent Application No. 201941034278, filed on August 26, 2019, entitled “TECHNIQUES FOR DETERMINING RESOURCES FOR COMMUNICATING OVER AN ACQUIRED CHANNEL,” and U.S. Patent Application No. 16 / 986,128, filed on August 20, 2020, entitled “TECHNIQUES FOR DETERMINING RESOURCES FOR COMMUNICATING OVER ANACQUIRED CHANNEL,” both of which are expressly incorporated herein by reference in their entirety.

[0003] background

[0004] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly to communicating over resources of acquired channels.

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems 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, and single-carrier frequency division multiple access (SC-FDMA) systems.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. For example, the fifth generation (5G) wireless communication technology (which may be referred to as 5G New Radio (5G NR)) is designed to expand and support diverse usage scenarios and applications relative to current mobile network generations. In one aspect, 5G communication technologies may include: enhanced mobile broadband for human-centric use cases for accessing multimedia content, services, and data; ultra-reliable low latency communication (URLLC) with certain specifications on latency and reliability; and massive machine type communication, which may allow a very large number of connected devices and the transmission of relatively small amounts of non-delay-sensitive information.

[0007] In some wireless communication technologies, a user equipment (UE) may acquire a channel, such as by using listen-before-talk (LBT) or other channel assessment procedures for the channel, receiving a configured grant from a base station, etc. However, the UE may not always know in advance when it will acquire the channel for transmission within a time slot.

[0008] Overview

[0009] The following is a brief summary of one or more aspects to provide a basic understanding of such aspects. This summary is not an exhaustive overview of all conceivable aspects and is neither intended to identify key or critical elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

[0010] According to an example, a method for wireless communication is provided.

[0012] In another example, a method for wireless communication is provided, the method comprising: receiving a start indication of a set of possible starting points for transmitting uplink communication within a time slot; detecting acquisition of a channel for transmitting uplink communication at a possible starting point in the set of possible starting points; selecting a set of resources for transmitting a data packet within the time slot; and transmitting the data packet to a base station on the selected set of resources.

[0013] In another example, a method for wireless communication includes: preparing multiple uplink communication instances for each possible starting point in a set of possible starting points for uplink communication within a time slot; and transmitting, based on a second possible starting point in the set of possible starting points, one uplink communication instance in the multiple uplink communication instances prepared based on a first possible starting point in the set of possible starting points.

[0014] In another example, a method for wireless communication includes: receiving uplink control information (UCI) including an indication of a set of resources for transmitting uplink communication within a mini-time slot; receiving uplink communication within the mini-time slot; and processing data packets of the uplink communication based on the indication of the set of resources.

[0033] Detailed description

[0034] Now, various aspects will be described with reference to the accompanying drawings. In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. However, it is apparent that such aspects can be practiced without these specific details.

[0035] The various features described generally relate to communicating based on acquiring a channel in a wireless network. In one example, based on acquiring a channel, a first node transmitting on the channel may indicate to a second node receiving the communication a portion of resources that can be used by the second node to transmit communications to the first node (or other nodes) when the channel is acquired. In one example, as the first node continues to transmit on the acquired channel, it may update the portion of resources that can be used by the second node (e.g., to increase the size of the resources when the first node completes the transmission and may not have utilized all the resources). For example, the size of the resources may correspond to the number of time slots associated with the acquired channel, the number of codewords within one or more time slots, etc. For example, the first node may be a user equipment (UE) that indicates to the base station the portion of resources used for downlink communications. In another example, the first node may be a base station that indicates to the UE the portion of resources used for uplink communications.

[0036] In another example, a user equipment (UE) may indicate the size of resources used to transmit uplink communications in uplink control information (UCI). For example, the size of the resources may correspond to the number of symbols (e.g., orthogonal frequency division multiplexing (OFDM), single-carrier frequency division multiplexing (SC-FDM), etc.) within a slot or mini-slot. For example, a mini-slot may correspond to the number of symbols within the slot that comprise the mini-slot. In some wireless communication technologies, a slot may be divided into multiple mini-slots, each of which may include several symbols (e.g., consecutive symbols) within the slot, and communication may occur within the mini-slot. In this regard, a mini-slot may have its own control region for transmitting control information regarding the mini-slot, demodulation reference signal (DM-RS) resources, a hybrid automatic repeat / request (HARQ) mechanism, and the like.

[0037] Given multiple possible transmission starting points in a timeslot (e.g., a subset of symbols in the timeslot), depending on when the channel is acquired, a UE may potentially begin transmitting at a symbol within a timeslot (e.g., the first symbol of a mini-slot). In one example, the set of possible starting points may be configured by the base station, which may be based on capabilities indicated by the UE. Additionally, in one example, the UE may concurrently prepare for uplink communications based on multiple possible starting points within a timeslot (and / or multiple possible sizes for uplink communications, which may be based on these starting points and the corresponding last symbol in the timeslot). In other examples, the UE may indicate capabilities regarding: the number of uplink communications that may be transmitted or prepared, the number of uplink symbols per timeslot that may be used to transmit uplink communications, the number of overlapping physical uplink shared channels (PUSCHs) that the UE may handle (or prepare) to account for uncertainty in LBT results, a preparation time for preparing for uplink communications, and the like. In any case, the base station may indicate the set of possible starting symbols based at least in part on the UE's capabilities. Furthermore, in some examples, uplink communications prepared based on one start symbol may be transmitted based on a different start symbol, where the waveforms used for the uplink communications are created to be position-independent, as further described herein (e.g., such as with position-independent demodulation reference signal (DMRS) / scrambling, data / scrambling, UCI multiplexing, etc.). In any case, the efficiency of channel acquisition-based communications may be improved in this regard.

[0038] The following will refer to Figures 1-12 The described features are presented in more detail.

[0039] As used in this application, the terms "component," "module," "system," and similar terms are intended to include computer-related entities such as, but not limited to, hardware, software, a combination of hardware and software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution, and components can be localized on a computer and / or distributed between two or more computers. In addition, these components can be executed from various computer-readable media having various data structures stored thereon. These components can communicate with the aid of local and / or remote processes, such as according to signals having one or more data packets, such as data from a component that interacts with a local system, another component in a distributed system, and / or other systems across a network such as the Internet via the signal. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0040] The technology described herein can be used in various wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms "system" and "network" are generally used interchangeably. A CDMA system can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 versions 0 and A are commonly referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. A TDMA system can implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA systems can implement technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM TMand other radio technologies. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies, including cellular (e.g., LTE) communications on shared radio frequency spectrum bands. However, the following description describes an LTE / LTE-A system for example purposes, and LTE terminology is used in most of the following description, but these techniques can also be applied beyond LTE / LTE-A applications (e.g., to fifth generation (5G) new radio (NR) networks or other next generation communication systems).

[0041] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. The various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to some examples may be combined in other examples.

[0042] Various aspects or features will be presented in the form of systems that may include a number of devices, components, modules, and the like. It should be understood and appreciated that the various systems may include additional devices, components, modules, and the like, and / or may not include all of the devices, components, modules, and the like discussed in conjunction with the figures. Combinations of these approaches may also be used.

[0043] Figure 11 is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also known as a wireless wide area network (WWAN)) may include a base station 102, a UE 104, an evolved packet core (EPC) 160, and / or a 5G core (5GC) 190. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell may include a base station. A small cell may include a femto cell, a pico cell, and a micro cell. In one example, the base station 102 may also include a gNB 180, as further described herein. In one example, some nodes of the wireless communication system may have a modem 240 and a communication component 242 for indicating resources related to transmitting on an acquired channel. Additionally, some nodes may have a modem 340 and a configuration component 342 for possibly configuring the UE for communication based on the acquired channel and / or configuring downlink communications based on resources indicated by the UE, as described herein. Although UE 104 is shown as having a modem 240 and a communication component 242, and base station 102 / gNB 180 is shown as having a modem 340 and a configuration component 342, this is an illustrative example, and substantially any node or type of node may include a modem 240 and a communication component 242 and / or a modem 340 and a configuration component 342 to provide the corresponding functionality described herein.

[0044] Base stations 102 configured for 4G LTE (which may be collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with EPC 160 via a backhaul link 132 (e.g., using an S1 interface). Base stations 102 configured for 5G NR (which may be collectively referred to as the Next Generation RAN (NG-RAN)) may interface with 5GC 190 via a backhaul link 184. Among other functions, base stations 102 may perform one or more of the following: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of alert messages. Base stations 102 may communicate with each other directly or indirectly (e.g., through EPC 160 or 5GC 190) over backhaul links 134 (e.g., using an X2 interface). Backhaul links 134 may be wired or wireless.

[0045] Base stations 102 can communicate wirelessly with one or more UEs 104. Each base station 102 can provide communication coverage for a corresponding geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102′ can have a coverage area 110′ that overlaps with the coverage area 110 of one or more macro base stations 102. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which can provide service to a restricted group, which may be referred to as a closed subscriber group (CSG). The communication link 120 between the base station 102 and the UE 104 may include uplink (UL) (also known as reverse link) transmissions from the UE 104 to the base station 102 and / or downlink (DL) (also known as forward link) transmissions from the base station 102 to the UE 104. The communication link 120 may utilize multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links may be over one or more carriers. For each carrier allocated in a carrier aggregation for transmission in the DL and / or UL directions for a total of up to Yx MHz (e.g., for x component carriers), the base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.). These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). A component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carrier may be referred to as a secondary cell (SCell).

[0046] In another example, some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be performed via a variety of wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0047] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communication to determine whether the channel is available.

[0048] Small cell 102′ may operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102′ may employ NR and use the same 5 GHz unlicensed spectrum as used by Wi-Fi AP 150. Small cell 102′ employing NR in the unlicensed spectrum may improve access network coverage and / or increase access network capacity.

[0049] Whether a small cell 102′ or a large cell (e.g., a macro base station), base station 102 may include an eNB, a gNode B (gNB), or other types of base stations. Some base stations, such as gNB 180, may operate in traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as a mmW base station. Extremely high frequency (EHF) is a portion of the RF spectrum in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW extends down to 3 GHz frequencies with a wavelength of 100 mm. Super high frequency (SHF) bands extend between 3 GHz and 30 GHz and are also referred to as centimeter waves. Communications using mmW / near-mmW radio frequency bands suffer from extremely high path loss and short range. The mmW base station 180 can utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range. The base station 102 referred to herein can include a gNB 180.

[0050] EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is a control node that handles signaling between UE 104 and EPC 160. Generally speaking, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets pass through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Services 176. IP Services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services. The BM-SC 170 provides functionality for provisioning and delivering MBMS user services. It serves as the entry point for content providers' MBMS transmissions, authorizes and initiates MBMS bearer services within the Public Land Mobile Network (PLMN), and schedules MBMS transmissions. The MBMS Gateway 168 distributes MBMS traffic to base stations 102 within the Multicast Broadcast Single Frequency Network (MBSFN) area that broadcasts specific services. It is also responsible for session management (start / stop) and collecting eMBMS-related charging information.

[0051] 5GC 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. AMF 192 may be in communication with a unified data management (UDM) 196. AMF 192 may be a control node that handles signaling between UE 104 and 5GC 190. Generally speaking, AMF 192 may provide QoS flow and session management. User Internet Protocol (IP) packets (e.g., from one or more UEs 104) may be passed through UPF 195. UPF 195 may provide UE IP address allocation for one or more UEs, as well as other functions. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, an intranet, an IP multimedia subsystem (IMS), PS streaming services, and / or other IP services.

[0052] A base station may also be referred to as a gNB, a Node B, an evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. Base station 102 provides an access point for UE 104 to EPC 160 or 5GC 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, positioning systems (e.g., satellite, terrestrial), multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, smart devices, robots, drones, industrial / manufacturing equipment, wearable devices (e.g., smart watches, smart clothing, smart glasses, virtual reality goggles, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), vehicles / vehicle equipment, meters (e.g., parking meters, electricity meters, gas meters, water meters, flow meters), gas pumps, large or small kitchen appliances, medical / healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional device. Some UEs 104 may be referred to as IoT devices (e.g., meters, gas pumps, monitors, cameras, industrial / manufacturing equipment, appliances, vehicles, robots, drones, etc.). IoT UEs may include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. In the present disclosure, eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), mMTC (massive MTC), etc., while NB-IoT may include eNB-IoT (enhanced NB-IoT), FeNB-IoT (further enhanced NB-IoT), etc. UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology.

[0053] In one example, the communication component 242 of the UE 104 can acquire a channel and can indicate a portion of the resources of the acquired channel that can be used for downlink communication in channel occupancy time (COT) sharing. In this example, the base station 102 can use the portion of the resources for the downlink communication, which can be based on the configuration component 342 configuring the portion of the resources based on the indication received from the UE 104. In another example, the communication component 242 of the UE 104 can determine a starting point within a time slot and / or a size for transmitting uplink communications. In one example, the communication component 242 can concurrently prepare uplink communications for transmission within a portion of the time slot based on the determined starting point. In one example, the configuration component 342 can configure the UE 104 to have a set of possible starting positions, which can be based on one or more indicated capabilities of the UE 104.

[0054] Now go to Figure 2-Figure 12 , various aspects are depicted with reference to one or more components and one or more methods that can perform the actions or operations described herein, where various aspects in dashed lines may be optional. Figure 4 、 5 The operations described in , 7, 8, and 11 are presented in a particular order and / or as being performed by example components, but it should be understood that the order of these actions and the components performing the actions may vary depending on the implementation. Furthermore, it should be understood that the following actions, functions, and / or described components may be performed by a specially programmed processor, a processor executing specially programmed software or computer-readable media, or by any other combination of hardware components and / or software components capable of performing the described actions or functions.

[0055] refer to Figure 2 One example implementation of the UE 104 may include various components, some of which are described above and further described herein, including components such as one or more processors 212 and memory 216 in communication via one or more buses 244, and a transceiver 202, which may be operable in conjunction with a modem 240 and / or a communication component 242 for communicating on resources of an acquired channel, in accordance with various aspects described herein.

[0056] In one aspect, the one or more processors 212 may include the modem 240 and / or may be part of the modem 240 using one or more modem processors. Thus, various functions associated with the communication component 242 may be included in the modem 240 and / or the processor 212 and, in one aspect, may be performed by a single processor, while in other aspects, different ones of these functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 212 may include any one or any combination of the following: a modem processor, a baseband processor, a digital signal processor, a transmit processor, a receiver processor, or a transceiver processor associated with the transceiver 202. In other aspects, some of the features of the one or more processors 212 and / or the modem 240 associated with the communication component 242 may be performed by the transceiver 202.

[0057] In addition, the memory 216 can be configured to store local versions of data and / or applications 275 used herein, or the communication component 242 and / or one or more subcomponents thereof executed by the at least one processor 212. The memory 216 can include any type of computer-readable medium usable by a computer or the at least one processor 212, such as random access memory (RAM), read-only memory (ROM), tape, magnetic disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, when the UE 104 is operating the at least one processor 212 to execute the communication component 242 and / or one or more subcomponents thereof, the memory 216 can be a non-transitory computer-readable storage medium that stores one or more computer-executable codes defining the communication component 242 and / or one or more subcomponents thereof and / or data associated therewith.

[0058] The transceiver 202 may include at least one receiver 206 and at least one transmitter 208. The receiver 206 may include hardware for receiving data and / or software code executable by a processor, the code comprising instructions and stored in memory (e.g., a computer-readable medium). The receiver 206 may be, for example, a radio frequency (RF) receiver. In one aspect, the receiver 206 may receive signals transmitted by at least one base station 102. Furthermore, the receiver 206 may process such received signals and may also obtain signal measurements such as, but not limited to, Ec / Io, signal-to-noise ratio (SNR), reference signal received power (RSRP), received signal strength indicator (RSSI), and the like. The transmitter 208 may include hardware and / or software executable by a processor for transmitting data, the code comprising instructions and stored in memory (e.g., a computer-readable medium). Suitable examples of the transmitter 208 may include, but are not limited to, an RF transmitter.

[0059] Moreover, in an aspect, the UE 104 may include an RF front end 288 that may operate in communication with the one or more antennas 265 and the transceiver 202 for receiving and transmitting radio transmissions, such as wireless communications transmitted by at least one base station 102 or wireless transmissions transmitted by the UE 104. The RF front end 288 may be connected to the one or more antennas 265 and may include one or more low noise amplifiers (LNAs) 290, one or more switches 292, one or more power amplifiers (PAs) 298, and one or more filters 296 for transmitting and receiving RF signals.

[0060] In one aspect, the LNA 290 can amplify the received signal to a desired output level. In one aspect, each LNA 290 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular LNA 290 and its specified gain value based on the desired gain value for a particular application.

[0061] Furthermore, for example, one or more PAs 298 can be used by the RF front end 288 to amplify the signal to obtain an RF output at a desired output power level. In one aspect, each PA 298 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular PA 298 and its specified gain value based on the desired gain value for a particular application.

[0062] Additionally, for example, one or more filters 296 can be used by the RF front end 288 to filter a received signal to obtain an input RF signal. Similarly, in one aspect, for example, a corresponding filter 296 can be used to filter the output from a corresponding PA 298 to produce an output signal for transmission. In one aspect, each filter 296 can be connected to a specific LNA 290 and / or PA 298. In one aspect, the RF front end 288 can use one or more switches 292 to select a transmit or receive path using a specific filter 296, LNA 290, and / or PA 298 based on a configuration as specified by the transceiver 202 and / or the processor 212.

[0063] As such, the transceiver 202 can be configured to transmit and receive wireless signals via the RF front end 288 through one or more antennas 265. In one aspect, the transceiver can be tuned to operate at a specified frequency so that the UE 104 can communicate, for example, with one or more base stations 102 or one or more cells associated with the one or more base stations 102. In one aspect, the modem 240 can configure the transceiver 202 to operate at the specified frequency and power level based on, for example, the UE configuration of the UE 104 and the communication protocol used by the modem 240.

[0064] In one aspect, modem 240 may be a multi-band, multi-mode modem that can process digital data and communicate with transceiver 202 to enable transmission and reception of digital data using transceiver 202. In one aspect, modem 240 may be multi-band and configured to support multiple frequency bands for a particular communication protocol. In one aspect, modem 240 may be multi-mode and configured to support multiple operating networks and communication protocols. In one aspect, modem 240 may control one or more components of UE 104 (e.g., RF front end 288, transceiver 202) to enable transmission and / or reception of signals from the network based on a specified modem configuration. In one aspect, the modem configuration may be based on the mode of the modem and the frequency bands used. In another aspect, the modem configuration may be based on UE configuration information associated with UE 104, such as provided by the network during cell selection and / or cell reselection.

[0065] In one aspect, the communication component 242 may optionally include: a resource indication component 252 for indicating a set of resources on which communications are transmitted in a first direction (e.g., uplink communications) and / or a set of resources on which communications are to be transmitted in a second direction (e.g., downlink communications), a capability indication component 254 for indicating one or more capabilities regarding communications ready for transmission in the first direction and / or concurrent or overlapping communications in the first direction, and / or a starting set determination component 256 for determining a set of possible starting points within a time slot for transmitting communications in the first direction.

[0066] In one aspect, processor 212 may correspond to Figure 12 Similarly, the memory 216 may correspond to one or more of the processors described in conjunction with the UE. Figure 12 The memory described by the UE in.

[0067] Reference Figure 3 , one example of an implementation of a base station 102 (e.g., base station 102 and / or gNB 180 as described above) may include various components, some of which have been described above, but including components such as one or more processors 312 and memory 316 in communication via one or more buses 344 and a transceiver 302, which is operable in conjunction with a modem 340 and a configuration component 342 to configure a UE 104 to transmit on the resources of the acquired channel.

[0068] The transceiver 302, receiver 306, transmitter 308, one or more processors 312, memory 316, applications 375, bus 344, RF front end 388, LNA 390, switch 392, filter 396, PA 398, and one or more antennas 365 may be the same as or similar to corresponding components of the UE 104 as described above, but are configured or otherwise programmed for base station operation rather than UE operation.

[0069] In one aspect, the configuration component 342 may optionally include: a resource determination component 352 for determining a set of resources over which communications may be transmitted in a second direction (e.g., downlink communications) and / or a set of resources over which communications may be transmitted in a first direction (e.g., uplink communications), a capability determination component 354 for determining one or more capabilities of the UE regarding communications prepared for transmission in the first direction and / or concurrent or overlapping communications in the first direction, and / or a starting set indication component 356 for indicating a set of possible starting points within a time slot for transmitting communications in the first direction.

[0070] In one aspect, processor 312 may correspond to Figure 12 Similarly, the memory 316 may correspond to one or more of the processors described in conjunction with the base station. Figure 12 The memory described in the base station.

[0071] Figure 4 A flow chart illustrating an example of a method 400 for indicating resources available for use in COT sharing. Figure 5 A flow chart illustrating an example of a method 500 for receiving an indication of resources available for use in COT sharing. For ease of illustration, methods 400 and 500 are described in conjunction with each other, although methods 400 and 500 need not be performed in conjunction. In one example, as described below, UE 104 may use Figure 1 and Figure 2 One or more components described in the method 400 may be used to perform the functions described in the method 400, and / or the base station 102 and / or other network components may use Figure 1 and Figure 3 In another example, the base station 102 and / or other network components may use one or more components described in the method 500 to perform the functions described in the method 500. Figure 1 and Figure 2 to perform the functions described in method 400, and / or UE 104 may use one or more components described in Figure 1 and Figure 3 One or more components described with respect to base station 102 in the method 500 may be used to perform the functions described in method 500.

[0072] In method 400, at block 402, a channel for transmitting communications in a first direction may be acquired. In one aspect, communication component 242 (e.g., in combination with processor 212, memory 216, transceiver 202, etc.) may acquire a channel for transmitting communications in the first direction. For example, where communication component 242 is located within UE 104, the first direction may be an uplink direction for transmitting communications from UE 104. In another example, where communication component 242 is located within base station 102, the first direction may be a downlink direction for transmitting communications from base station 102. In one example, acquiring the channel may include performing a listen-before-talk (LBT) or other clear channel assessment (CCA) procedure to determine when a channel or related resources will become available, and / or transmitting an indication that the device is acquiring an available channel. Thus, in one example, communication component 242 may periodically perform the LBT process until the channel is acquired within a time period (e.g., at the beginning of one or more slots, mini-slots, symbols, etc.).

[0073] In method 400, at block 404, control information may be generated that includes an indication of a set of resources available for transmitting communications in a second direction when the channel is acquired. In one aspect, resource indication component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) may generate control information that includes the indication of the set of resources available for transmitting communications in the second direction when the channel is acquired. For example, where communication component 242 is located within UE 104, the second direction may be a downlink direction for transmitting communications from base station 102. In another example, where communication component 242 is located within base station 102, the second direction may be an uplink direction for transmitting communications from UE 104. For example, resource selection component 252 may determine the set of resources based on an amount of resources to be used to transmit communications in the first direction. Additionally, as further described herein, while communications are being transmitted in the first direction, the resources available for transmitting in the second direction may be updated (e.g., increased).

[0074] In method 400, at block 406, control information may be transmitted in a first opportunity when a channel is acquired. In one aspect, resource indication component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) may transmit the control information in a first opportunity when the channel is acquired. For example, where communication component 242 is located within UE 104, resource indication component 252 may transmit the control information in uplink control information (UCI) in a first opportunity for transmitting a physical uplink shared channel (PUSCH). For example, where communication component 242 is located within base station 102, resource indication component 252 may transmit the control information in downlink control information (DCI) in a first opportunity for transmitting a physical downlink shared channel (PDSCH). A receiving node may receive the control information and may determine a set of resources for transmitting in a second direction. Figure 6 An example is shown in .

[0075] Figure 6 An example of resource allocations 600, 602, 604 with varying resources allocated for PUSCH and downlink (e.g., where the communication component 242 is located within the UE 104, the first direction is uplink, and the second direction is downlink) is illustrated. In resource allocation 600, the UE 104 can acquire a channel and can transmit a PUSCH, where the first two PUSCH symbols can include UCI including an initial indication of a downlink portion for COT sharing, as represented by resource allocation 602. In this example, a base station can receive the PUSCH from the UE 104 and can determine that the downlink portion at the end of the channel can be used to transmit downlink communications, as indicated by the UCI in the PUSCH.

[0076] In method 500, at block 502, control information may be received at a first opportunity, the control information including an indication of a set of resources available for transmitting communications in a second direction and during a second opportunity when a different node has acquired a channel. In one aspect, resource determining component 352 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, configuration component 342, etc.) may receive control information at a first opportunity, the control information including an indication of a set of resources available for transmitting communications in a second direction and during a second opportunity when a different node has acquired a channel. For example, resource determining component 352 may receive the control information in a first direction (e.g., uplink) and may receive the control information from the different node (e.g., UE 104) that has acquired the channel. In one example, the control information may include UCI from UE 104 indicating PDSCH resources on which base station 102 may transmit a PDSCH during a second opportunity. For example, the UCI may indicate one or more parameters used to determine the second opportunity and / or related resources, such as one or more symbols or symbol offsets for the second opportunity (e.g., the DL portion in resource allocation 602). In this regard, UE 104 (e.g., a different node) has acquired the channel and may share the resources with base station 102 by allowing base station 102 to transmit the DL portion during the COT.

[0077] In method 400, optionally at block 408, an update to the set of resources available for transmitting communications in the second direction when the channel is acquired can be transmitted. In one aspect, resource indication component 252 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) can transmit an update to the set of resources available for transmitting communications in the second direction when the channel is acquired. For example, if communication component 242 is located within UE 104, resource indication component 252 can transmit the update in a subsequent opportunity for transmitting a PUSCH. For example, if communication component 242 is located within base station 102, resource indication component 252 can transmit the control information in a subsequent opportunity for transmitting a PDSCH. A receiving node can receive the update and can determine the updated set of resources for transmitting in the second direction.

[0078] Refer again Figure 6, in resource allocation 600, UE 104 may transmit an update to the set of resources in UCI in a second pair of PUSCH symbols, the update including an updated indication of the downlink portion for COT sharing, as represented by resource allocation 604. In this example, the base station may receive the update from UE 104 and may determine an increase in resources at the end of the channel that may be used to transmit the downlink portion of downlink communications, as indicated by the UCI in the second pair of PUSCH symbols.

[0079] In a specific example, when a UE shares a COT with a gNB, the UE can indicate which portions can be used for downlink (DL) (e.g., time offset from the UCI, duration of the DL portion, etc.). Indicating this from the first UCI can limit UE scheduling flexibility (e.g., if the UE does not know how many uplink (UL) timeslots it has data for, the UE may not be able to tell the gNB exactly where to start DL). Initially, the UE may indicate no DL or be conservative with its allocated DL timeslots, but the UE may later indicate that DL is allowed and / or grant more DL timeslots to the gNB. As shown in resource allocations 600, 602, and 604 and explained above, for example, the UE may indicate some DL portion in an initial UCI (e.g., a configured grant PUSCH UCI (CG-UCI)), but the UE may update this in subsequent CG-UCIs. For example, CG-UCI may refer to UCI transmitted on CG resources, where CG resources may be configured by radio resource control (RRC) signaling and / or dynamically activated via dynamic grants. In another example, because the gNB may detect the initially transmitted CG-UCI but not the subsequent CG-UCI, the UE may be allowed to increase the DL assignment but perhaps not decrease the DL assignment (e.g., the UE may not be able to change its portion marked as DL to UL). Additionally, in the event that the gNB does not detect a later update, the gNB may use only the portion indicated as DL in the initial CG-UCI for DL. A gNB that detects the updated UCI may use the extended portion. In yet another example, a gNB that shares its COT with the UE may update its portion marked as DL (increase the UL portion, rather than decrease it) to avoid the problem of the UE not detecting the later update. In these and other examples, for a UE-initiated COT, the UE may decide to end early for the UL.

[0080] In method 500, optionally at block 504, an update to a set of resources available for transmitting communications in a second direction when the different node has acquired the channel can be received. In one aspect, resource determining component 352 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, configuration component 342, etc.) can receive the update to a set of resources available for transmitting communications in a second direction when the different node has acquired the channel. For example, resource determining component 352 can receive the update from UE 104 in additional control information (e.g., UCI) or as a resource grant or other indication. The update can be received after the initial control information indicating the set of resources and can modify the set of resources. For example, as Figure 6 As shown in , the update can indicate an updated set of resources (such as the DL portion in resource allocation 604), which can include the set of resources in the initial indication of the DL portion in resource allocation 602, in addition to other symbols preceding the DL portion in resource allocation 602. As described, it is contemplated that updates to a set of resources only increase the set of resources, not decrease the set of resources. In this regard, in one example, if the update decreases the set of resources, resource determining component 352 can discard or otherwise ignore the received update and can transmit downlink communications on the set of resources initially indicated in the control information received at block 502.

[0081] In method 500, communications may be transmitted to one or more nodes in a set of resources, optionally at block 506. In an aspect, configuration component 342 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, etc.) may transmit communications to one or more nodes in a set of resources (e.g., as in the initial control information received at block 502 or as updated at block 504). Thus, for example, configuration component 342 may transmit downlink communications in a DL portion indicated in the control information (e.g., the DL portion of resource allocation 602) and / or in an updated DL portion (e.g., the DL portion of resource allocation 604) based on whether an updated set of resources is received in the update.

[0082] As explained above, these concepts can be equally applied to UE 104 and base station 102 such that, in one example, base station 102 can perform method 400 for acquiring a channel; generate control information (e.g., DCI) indicating a set of resources in the COT for base station 102 that can be used for uplink communications from UE 104; and transmit the control information and / or updates to the control information to UE 104. Similarly, in this example, UE 104 can perform method 500 for receiving control information from base station 102 indicating a set of resources on which UE 104 can transmit uplink communications during the COT of base station 102. ; receiving an update to the set of resources; and / or transmitting an uplink communication on the set of resources.

[0083] Figure 7 A flow chart illustrating an example of a method 700 for a UE to select resources for transmitting a data packet in a time slot in uplink communication. Figure 8 A flow chart illustrating an example of a method 800 for a BS to configure a UE to select resources for transmitting a data packet in a time slot in an uplink communication. For ease of illustration, methods 700 and 800 are described in conjunction with each other, although methods 700 and 800 need not be performed in conjunction. In one example, UE 104 may use Figure 1-2 One or more components described in the method 700 may be used to perform the functions described in the method 700, and / or the base station 102 and / or other network components may use Figure 1 and Figure 3 One or more components described in the method 800 may be used to perform the functions described in the method 800.

[0084] In method 700, at block 702, a set of possible starting points for transmitting uplink communications within a time slot can be determined. In one aspect, starting set determining component 256 (e.g., in conjunction with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) can receive the set of possible starting points for transmitting uplink communications within the time slot. For example, starting set determining component 256 can receive the set of possible starting points from base station 102 (e.g., in one configuration) or can determine the set of possible starting points based on one or more parameters.

[0085] In method 800, optionally at block 802, a starting indication of a set of possible starting points for transmitting uplink communications within a time slot can be transmitted. In one aspect, starting set indicating component 356 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, configuration component 342, etc.) can transmit the starting indication of the set of possible starting points for transmitting uplink communications within the time slot. In this example, starting set indicating component 356 can transmit the set of possible starting points to UE 104, and / or starting set determining component 256 can receive the set of possible starting points from base station 102. For example, starting set indicating component 356 can transmit the indication of the set of possible starting points to UE 104 in RRC signaling, in a configuration message or parameter in a DCI, or in other signaling.

[0086] For example, the set of possible starting points may correspond to a starting symbol of one or more mini-slots defined within the time slot, and / or the indication may indicate an index of the symbol within the mini-slot, an index of the mini-slot within the time slot, and so on. In this example, the base station 102 may also configure one or more time slots to include one or more mini-slots within the one or more time slots, as described, where a mini-slot may include a set of symbols (e.g., consecutive symbols) within the time slot. The UE 104 may be able to support mini-slot communications, full-slot communications starting from one or more mini-slots (which may include the ability to concurrently prepare uplink communications for each possible transmission length from different possible starting points in the time slot to the end of the time slot), and / or a mix of concurrent preparation of mini-slots and uplink communications until the end of the time slot. Specific non-limiting examples are provided in Figure 9 Chinese commentary.

[0087] Figure 9 Examples of resource allocations 900, 902, and 904 for UEs transmitting in one or more mini-slots are illustrated. In one example, the set of possible starting symbols may include the start symbol for each of the one or more mini-symbols, and the UE 104 may determine the start symbol based on the configured set of possible starting symbols and when the channel was acquired (e.g., when LBT was passed or otherwise acquired based on acquisition of the channel via LBT). In one example, the configured set of possible starting symbols may be determined based on the indicated capabilities of the UE 104.

[0088] In one example, to provide multiple LBT opportunities within a slot, the UE may be given a first configuration set for slot-based allocation, which may have only one LBT starting point per slot. In another example, the UE may be given a second configuration set for non-overlapping mini-slot-based allocation (e.g., as shown in resource configuration 900). UEs that support multiple PUSCHs per slot and have mini-slot capabilities may support this mode. This naturally has multiple LBT starting points per slot corresponding to each mini-slot. A possible problem that arises is that in a slot, multiple PUSCHs may be used, so multiple UCIs, multiple DMRSs, blocking multiple HARQ IDs, etc. may have to be sent. In one example, it may be implicitly understood that the UE predetermines whether it is using a slot configuration or a mini-slot configuration and performs transmissions accordingly (e.g., using a slot configuration to obtain the medium and then switching to a mini-slot configuration).

[0089] Various aspects described herein may also allow for full-slot PUSCH transmissions or other transmissions that may span mini-slots (and may utilize parallel PUSCH preparation for transmissions of various sizes), as shown in the example of resource allocation 902, as well as a mix of mini-slot configurations and parallel PUSCH preparations, as shown in the example of resource allocation 904. In these examples, the UE 104 may concurrently prepare PUSCH for various transmission lengths that may overlap in time, as further described herein.

[0090] For a UE that has the capability to concurrently prepare multiple overlapping PUSCHs (including full slots and mini slots), each PUSCH having a length from each starting point in a set of starting points to the end of the slot (e.g., as opposed to only non-overlapping and / or fixed-length mini slot transmissions, e.g., as shown in resource allocation 900), it may be more efficient for the UE to transmit PUSCHs in full slots starting from a symbol passed through the LBT (e.g., as shown in resource allocation 902) because the UE may incur less UCI overhead, less DMRS overhead, fewer HARQ IDs, etc. for a single PUSCH transmission. This may be a different UE capability than the UE's capability to transmit N PUSCHs in a slot, and the UE may indicate (e.g., to a base station) the capability to transmit PUSCHs in full slots as described above and further used herein to receive a set of possible starting points for PUSCH transmissions. In one example, when the UE prepares all PUSCHs associated with a slot before the slot itself, a UE with minislot capability can prepare two PUSCHs of length 7 symbols each (e.g., non-overlapping minislots for 2 starting points within a slot). A UE with the capability to prepare parallel full-slot PUSCH and minislot PUSCH can prepare two PUSCHs, one of length 14 symbols and the other of length 7 symbols (e.g., overlapping full-slot (14 symbols) and minislot (7 symbols) PUSCHs for 2 starting points within a slot). The transport block (TB) size can be the same for full and minislots, or can depend on the number of symbols from the start point to the end of the slot (in this example, 14 symbols for the first PUSCH and 7 symbols for the second PUSCH). The UE capability to prepare PUSCH of different lengths (14 symbols and 7 symbols in this example) in parallel can be indicated for rate matching to each of these lengths in order to reach these lengths (e.g., and not for puncturing). Although only the time slots in which LBT is passed are described herein, for subsequent time slots, the UE may use full-slot-based transmissions, etc., depending on its processing timeline. Additionally, as described herein, in some examples, the UE may support preparing multiple uplink communication instances for transmission in parallel (e.g., concurrently) based on a set with multiple possible starting points.

[0091] In this example, in method 700, optionally at block 704, a capability indication related to the capabilities of possible starting points for transmitting uplink communications within a time slot can be transmitted to a base station. In one aspect, capability indication component 254 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) can transmit a capability indication related to the capabilities of possible starting points for transmitting uplink communications within a time slot to a base station (e.g., base station 102). For example, capability indication component 254 can transmit one or more of the capabilities (or indications of the capabilities) of supporting one or more possible starting points from a set of possible starting points within the time slot and a transmission length corresponding to each possible starting point from the set of possible starting points. In this example, there can be overlap in the possible transmission resources for which a PUSCH is prepared, with these possible transmission resources having different starting points for transmitting uplink communications (and / or wherein the transmission of each uplink communication is rate matched corresponding to the transmission length), such as shown in resource allocations 902 and / or 904. In one example, conveying the capability may include conveying support for full slot transmission from one or more starting points within the slot to the end of the slot (e.g., and thereby parallel preparation of PUSCHs), and / or support for a mix of mini-slots and parallel preparation of PUSCHs, as described above. In another example, the UE capability may include the number of parallel PUSCHs (overlapping) of different lengths (e.g., from different starting points of the slot to the end of the slot) that the UE can prepare. For example, the UE's ability to prepare parallel PUSCHs may be used for rate matching to different lengths (multi-PUSCH preparation) rather than for puncturing a single long PUSCH.

[0092] In another example, the capability indication component 254 can transmit one or more of a capability (or an indication of capability) to support at least one of the following: a number of uplink communications that can be transmitted within the time slot, a number of uplink communication instances that can be concurrently prepared for transmission within the time slot, a number of PUSCH symbols per time slot that can be prepared, each time slot including overlapping PUSCHs (e.g., the number can be greater than 14 because the prepared PUSCHs can overlap), or a time for preparing the uplink communication. For example, the capability indication component 254 can transmit the indication in RRC signaling, UCI, etc., which can be based on a request for capability information received from the base station 102 or the like.

[0093] In this example, in method 800, optionally at block 804, a capability indication of capabilities associated with possible starting points for transmitting uplink communications within a time slot can be received. In one aspect, capability indication component 254 (e.g., in conjunction with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) can receive the capability indication of capabilities associated with possible starting points for uplink communications within the time slot. In this example, starting set indicating component 356 can determine a set of possible starting points based on one or more indicated capabilities.

[0094] For example, options / parameters for defining UE capabilities (e.g., parameters of capability indication) may include: 1) the number of PUSCHs that the UE can actually transmit (which may be defined in the NR but may be non-overlapping); 2) the number of overlapping PUSCHs that the UE can handle for parallel transmission, which may be based on LBT results; 3) the number of PUSCH symbols per slot that the UE can handle (considering that some PUSCHs may have overlapping symbols, this number may be greater than 14); or 4) PUSCH preparation time (potentially as a function of the number of symbols). The PUSCH preparation time may be different from the UL grant to PUSCH time (e.g., the PUSCH preparation time may not need to include DCI decoding time, etc.). In addition, the PUSCH preparation time may indicate how quickly the UE reacts to LBT failure. For example, in the case where the UE prepares PUSCH for the full slot, if LBT fails, the UE may prepare a new PUSCH to start at symbol 7. In one example, as described, the UE can communicate this capability to the gNB so that the gNB can more efficiently configure the UE (and / or the communication system between the UE and the gNB). In another example, if the gNB knows that the UE can handle all LBT points using only one PUSCH, the gNB may not need to configure as many HARQ IDs for configured grant (CG) transmissions. In yet another example, the set of possible starting points can be selected by the UE.

[0095] In method 700, optionally at block 706, multiple uplink communication instances can be prepared for each possible starting point in a set of possible starting points for uplink communication in the time slot. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) can prepare multiple uplink communication instances for each possible starting point in the set of possible starting points for uplink communication in the time slot. For example, communication component 242 can prepare the multiple instances concurrently. As described, communication component 242 can prepare the multiple instances based on the set of possible starting points as determined by UE 104 or otherwise indicated by base station 102 (based on an indication of capabilities or otherwise). For example, in Figure 9 , the possible starting points can correspond to (at least a portion of) the starting symbol in each mini-slot. Thus, for example, as shown for resource allocation 902, communication component 242 can prepare instances of overlapping uplink communications for full-slot PUSCH, mini-slot 1, mini-slot 2, and mini-slot 3, depending on the possible starting points and corresponding transmission lengths. For resource allocation 904 (e.g., and depending on the capabilities of UE 104), communication component 242 can prepare two different uplink transmission instances within the slot, which can include overlapping uplink communications for mini-slot 1 and mini-slot 3, mini-slot 2 and mini-slot 3, or mini-slot 2 and mini-slot 4. Additional examples of preparing uplink communication instances are also provided below. Figure 10 described in .

[0096] In method 700, at block 708, acquisition of a channel for transmitting uplink communications at one of the possible starting points in the set of possible starting points can be detected. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) can detect acquisition of a channel for transmitting uplink communications at one of the possible starting points in the set of possible starting points. For example, communication component 242 can detect acquisition of a channel based on a successful LBT procedure. In this example, communication component 242 can observe the channel to determine whether other devices are communicating on the channel and / or can transmit a message to acquire the channel upon determining that the channel is available, etc.

[0097] In method 700, at block 710, a set of resources for transmitting a data packet within the time slot may be selected. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) may select a set of resources for transmitting a data packet within the time slot. For example, communication component 242 may select a set of resources based on a set of possible starting points and based on an acquisition channel. For example, communication component 242 may select a set of resources to begin at the first starting point after acquiring a channel and continue to the end of the corresponding mini-slot or time slot. For example, a UE with mini-slot capability may use a mini-slot length for data packets. A UE capable of preparing overlapping PUSCHs (e.g., concurrently preparing PUSCHs of different sizes) and / or capable of faster PUSCH preparation (as described above and further herein) may select a length longer than a mini-slot, e.g., as illustrated by resource allocations 902 and 904.

[0098] In one example, communication component 242 can select a resource set for transmitting a full-slot PUSCH from a starting point and / or for transmitting based on a mix of mini-slots and parallel PUSCH. In one example, communication component 242 can also select an end point for transmission of a data packet (e.g., the end of a mini-slot, the end of a slot, or another symbol within a slot). In another example, communication component 242 can also select a resource set when transmitting only mini-slots (e.g., as shown in resource allocation 900). In this example, communication component 242 can select resources for mini-slot transmissions even without parallel PUSCH preparation capabilities. An example is shown in FIG10.

[0099] Figure 10 An example of resource allocation for mini-slots 1000 is illustrated, where in a first slot (Slot 1), each mini-slot is used to transmit PUSCH due to starting point ambiguity caused by LBT. Also in a second slot (Slot 2), if LBT occurs in the middle of Slot 1, the UE may need to use mini-slots due to processing timeline constraints (although it could use a full slot). In some examples, some HARQ IDs may not be available in Slot 2 because they were previously used (e.g., for the mini-slots in Slot 1) and the UE may be awaiting feedback from the gNB. In this example, resource indication component 252 may determine to switch from a 4-mini-slot mode to a 2-mini-slot mode (e.g., as shown in Slot 2 in the second example of 1000) to reduce the number of required HARQ IDs.

[0100] In method 700, optionally at block 712, UCI can be generated that includes an indication of a size of a set of resources used to transmit the data packet and the UCI within the time slot. In one aspect, resource indicating component 252 (e.g., in conjunction with processor(s) 212, memory 216, transceiver 202, communication component 242, etc.) can generate UCI that includes an indication of a size of a set of resources used to transmit the data packet and the UCI within the time slot.

[0101] In method 700, at block 714, data packets and / or UCI may be transmitted to a base station on the selected set of resources. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) may transmit data packets and / or UCI to a base station (e.g., base station 102) on the selected set of resources. In one example, communication component 242 may transmit the data packets from a starting point using rate matching. For example, communication component 242 may map at least the UCI (which may include CG-UCI and / or may have HARQ-ACK or redundancy versions, etc.) assuming a minimum number of symbols allowed in the selected resources. In one example, communication component 242 may map the CG-UCI based on all used symbols in the resource set, possibly at the expense of increased complexity at the gNB (e.g., to perform blind decoding for different lengths). Communication component 242 can also restrict mapping of other UCI (eg, other UCI within the slot) to the same number (minimum guarantee) or can use more symbols because these other UCIs may be decoded after the CG-UCI is decoded.

[0102] In method 800, at block 806, UCI including an indication of a set of resources used to transmit uplink communications within a time slot may be received. In one aspect, resource determining component 352 (e.g., in conjunction with processor(s) 312, memory 316, transceiver 302, configuration component 342, etc.) may receive UCI including an indication of a set of resources used to transmit uplink communications within the time slot. For example, the UCI may indicate a size or length of the resources, a starting point, etc., as described above.

[0103] In method 800, at block 808, uplink communications received in the time slot can be processed based on the indication of the set of resources. In one aspect, configuration component 342 (e.g., in combination with processor(s) 312, memory 316, transceiver 302, etc.) can process uplink communications received in the time slot based on the indication of the set of resources. For example, configuration component 342 can determine the resources on which to transmit the uplink communications based on the size or length of the resources, the starting point, etc. (as indicated in the UCI). In one example, the UCI can include UCI transmitted for each PUSCH in one or more time slots or mini-slots (e.g., as shown in resource allocations 902, 904), etc.

[0104] Figure 11 A flow chart illustrating an example of a method 1100 for performing concurrent preparations for uplink communications in accordance with various aspects described herein. In one example, a UE 104 may use Figure 1-2 One or more components described in the method 1100 are used to perform the functions described in the method 1100.

[0105] In method 1100, at block 1102, multiple uplink communication instances may be prepared for each possible starting point in a set of possible starting points for uplink communication within a time slot. In one aspect, communication component 242 (e.g., in conjunction with processor(s) 212, memory 216, transceiver 202, etc.) may prepare multiple uplink communication instances for each possible starting point in a set of possible starting points for uplink communication within a time slot. For example, communication component 242 may determine the set of possible starting points based on a configuration from a base station (which may be based on capabilities indicated by the UE), based on capabilities or preferences determined at UE 104, etc. For example, these uplink communication instances may correspond to multiple possible starting points for communication and / or corresponding sizes or lengths (e.g., as illustrated in resource allocations 902, 904). Communication component 242 may prepare multiple instances concurrently to save processing time.

[0106] In one specific example, in method 1100, at block 1104, one of the multiple uplink communication instances prepared based on a first possible starting point in the set of possible starting points may be transmitted based on a second possible starting point in the set of possible starting points within the time slot. In one aspect, communication component 242 (e.g., in combination with processor(s) 212, memory 216, transceiver 202, etc.) may transmit one of the multiple uplink communication instances prepared based on the first possible starting point in the set of possible starting points based on the second possible starting point in the set of possible starting points within the time slot. For example, communication component 242 may transmit one of the multiple uplink communication instances based on a determination that the first and second possible starting points in the set of possible starting points correspond to resources of the same size or length. For example, referring to resource allocation 904, communication component 242 may transmit mini-slot 1, where mini-slot 2 is shown as having failed the first two LBTs and passed the third LBT, which may be based on a determination that mini-slot 1 and mini-slot 2 have the same size or length.

[0107] In one example, in the case of a mix of mini-slots and parallel PUSCH preparation, as shown, for example, at resource allocation 904, communication component 242 can generate the PUSCH Tx waveform to be position-independent (e.g., DMRS position and / or scrambling can be position-independent, data scrambling can be position-independent, UCI multiplexing can be position-independent, etc.), which can refer to the ability of the PUSCH Tx waveform to be transmitted at substantially any of these starting points. This can also allow PUSCH prepared for mini-slot 1 to be reused for mini-slot 2. For example, UCI multiplexing can depend on which symbols it falls on, and thus can be updated so that UCI multiplexing occurs independently of mini-slot position. In one example, UCI can be included only if it overlaps in the first shifted position. PUSCH can be discarded when UCI is present; otherwise, UCI can be deferred. For example, if the PUSCH preparation time is only 4 symbols and mini-slot 1 is 7 symbols long, mini-slot 2 and mini-slot 4 may not need to be prepared before LBT—for example, they can be prepared based on the LBT results. The gNB can have similar behavior.

[0108] Figure 12 1 is a block diagram of a MIMO communication system 1200 including a base station 102 and a UE 104. The MIMO communication system 1200 may be described with reference to Figure 1 The base station 102 may be a reference to the aspects of the wireless communication access network 100 described herein. Figure 1 12. Examples of various aspects of base station 102 are described. Base station 102 may be equipped with antennas 1234 and 1235, while UE 104 may be equipped with antennas 1252 and 1253. In MIMO communication system 1200, base station 102 may be able to transmit data simultaneously over multiple communication links. Each communication link may be referred to as a "layer," and the "rank" of a communication link may indicate the number of layers used for communication. For example, in a 2x2 MIMO communication system where base station 102 transmits two "layers," the communication link between base station 102 and UE 104 may have a rank of 2.

[0109] At base station 102, transmit (Tx) processor 1220 may receive data from a data source. Transmit processor 1220 may process the data. Transmit processor 1220 may also generate control symbols or reference symbols. Transmit MIMO processor 1230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, or reference symbols, as applicable, and may provide output symbol streams to transmit modulators / demodulators 1232 and 1233. Each modulator / demodulator 1232 to 1233 may process its own output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator / demodulator 1232 to 1233 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a DL signal. In one example, the DL signals from modulators / demodulators 1232 and 1233 may be transmitted via antennas 1234 and 1235, respectively.

[0110] UE 104 may be a reference Figure 1-2 Examples of various aspects of UE 104 are described. At UE 104, UE antennas 1252 and 1253 can receive DL signals from base station 102 and can provide received signals to modulators / demodulators 1254 and 1255, respectively. Each modulator / demodulator 1254-1255 can condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each modulator / demodulator 1254-1255 can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 1256 can obtain received symbols from modulators / demodulators 1254 and 1255, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive (Rx) processor 1258 may process (eg, demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 104 to a data output, and provide decoded control information to a processor 1280 or memory 1282 .

[0111] Processor 1280 may, in some cases, execute stored instructions to instantiate communication component 242 (e.g., see Figure 1 and 2 ).

[0112] On the uplink (UL), at UE 104, a transmit processor 1264 may receive and process data from a data source. Transmit processor 1264 may also generate reference symbols for a reference signal. The symbols from transmit processor 1264 may be precoded by transmit MIMO processor 1266, if applicable, further processed by modulators / demodulators 1254 and 1255 (e.g., for SC-FDMA, etc.), and transmitted to base station 102 based on communication parameters received from base station 102. At base station 102, the UL signals from UE 104 may be received by antennas 1234 and 1235, processed by modulators / demodulators 1232 and 1233, detected by MIMO detector 1236, if applicable, and further processed by receive processor 1238. Receive processor 1238 may provide decoded data to a data output and to processor 1240 or memory 1242.

[0113] Processor 1240 may, in some cases, execute stored instructions to instantiate configuration component 342 (e.g., see Figure 1 and 3 ).

[0114] The components of UE 104 may be implemented individually or collectively using one or more ASICs adapted to perform some or all applicable functions in hardware. Each of the modules mentioned may be a device for performing one or more functions related to the operation of MIMO communication system 1200.

Each of the components mentioned may be a device for performing one or more functions related to the operation of MIMO communication system 1200.
