Technical Field

[0004] In general, the following text relates to wireless communication, and more specifically, to the coexistence of autonomous (e.g., permissionless) uplink transmission and permission-based uplink transmission. Background Technology

[0005] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems (e.g., Long Term Evolution (LTE) systems or New Radio (NR) systems). A wireless multiple access communication system may include multiple base stations or access network nodes, each supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)) simultaneously.

[0006] In some wireless communication systems, the wireless medium can be divided into multiple channels, each covering a separate, non-overlapping frequency range. Some channels may be in licensed frequency bands, while others may be in unlicensed or shared frequency bands. One or more wireless devices (e.g., UEs) can transmit simultaneously (i.e., during the same time period) on multiple channels, thereby increasing the number of messages that can be transmitted concurrently. Summary of the Invention

[0007] The described technology relates to improved methods, systems, devices, or apparatuses supporting the coexistence of autonomous (e.g., permissionless) uplink (UL) transmissions and permitted UL transmissions. A wireless device can schedule a first scheduled transmission and a second autonomous transmission on different channels during a subframe. The wireless device can then determine that it does not have sufficient power to transmit both the first scheduled transmission and the second autonomous transmission during that subframe. The wireless device can select one of the two transmissions based at least in part on priority information. For example, the priority information can instruct the wireless device to prioritize the first scheduled transmission. The wireless device can transmit the first scheduled transmission and can discard the second autonomous transmission or reschedule the second autonomous transmission for another subframe.

[0062] In some wireless communication systems, the base station can provide scheduling information to user equipment (UE). The UE can use the scheduling information to determine when it can transmit to the base station on the uplink (UL) channel. The base station can also indicate time periods during which the UE can autonomously transmit. The UE can then transmit autonomously during these time periods.

[0063] In some examples, the base station can identify different access channels for different channels. For example, the base station can indicate that a first channel is reserved for scheduled transmission during a first time period, and can indicate that a second channel is available for autonomous transmission during a second time period.

[0064] In some cases, a UE may have scheduled and autonomous transmissions scheduled for the same time period and may transmit both on different channels. However, the UE may have limited power resources. For example, the UE may not have sufficient power to transmit both scheduled and autonomous transmissions at the power level necessary for the transmission to be successfully received at its destination.

[0065] In such power-constrained scenarios, the UE can utilize priority information to determine how to proceed. For example, the UE can always prioritize scheduled transmissions over autonomous transmissions. In other examples, the UE can receive priority information from the base station and prioritize scheduled or autonomous transmissions based on this information. In some examples, the UE can indicate in a power margin report whether it will attempt to send both scheduled and autonomous transmissions simultaneously.

[0066] First, various aspects of this disclosure are described in the context of a wireless communication system. Further, various aspects of this disclosure are illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to the coexistence of autonomous (e.g., permissionless) uplink transmission and permission-based uplink transmission (e.g., in multi-carrier licensed assisted access).

[0067] Figure 1Examples of a wireless communication system 100 according to various aspects of this disclosure are shown. The wireless communication system 100 includes a base station 105, a user interface unit (UE) 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, or a New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (i.e., mission-critical) communication, low-latency communication, and communication with low-cost and low-complexity devices.

[0068] Base station 105 can wirelessly communicate with UE 115 via one or more base station antennas. Each base station 105 can provide communication coverage for a corresponding geographical coverage area 110. The communication link 125 shown in the wireless communication system 100 can include uplink transmission from UE 115 to base station 105 or downlink transmission from base station 105 to UE 115. Control information and data can be multiplexed on the uplink or downlink channel according to various technologies. For example, control information and data can be multiplexed on the downlink channel using time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM technologies. In some examples, control information transmitted during the transmission time interval (TTI) of the downlink channel can be distributed in a cascaded manner between different control areas (e.g., between a common control area and one or more UE-specific control areas).

[0069] UE 115 can be distributed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. UE 115 can also be referred to as a mobile station, user station, mobile unit, user cell, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile user station, access terminal, mobile terminal, radio terminal, remote terminal, mobile phone, user agent, mobile client, client, or any other suitable term. UE 115 can also be a cellular phone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, tablet computer, laptop computer, cordless phone, personal electronic device, handheld device, personal computer, wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, machine-type communication (MTC) device, appliance, automobile, etc.

[0070] In some cases, UE 115 may also be able to communicate directly with other UEs (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UEs 115 in a group of UEs 115 utilizing D2D communication may be within the cell's coverage area 110. Other UEs 115 in such a group may be outside the cell's coverage area 110 or otherwise unable to receive transmissions from base station 105. In some cases, the group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some cases, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed independently of base station 105.

[0071] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices that can provide automated communication between machines, i.e., machine-to-machine (M2M) communication. M2M or MTC can refer to data communication technologies that allow devices to communicate with each other or with a base station without human intervention. For example, M2M or MTC can refer to communication from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application, which can then utilize or present that information to humans interacting with the program or application. Some UE 115 devices can be designed to collect information or automate machine behavior. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0072] In some cases, MTC devices can operate using half-duplex (one-way) communication at reduced peak rates. MTC devices can also be configured to enter a power-saving mode (e.g., a "deep sleep" mode) when not engaged in active communication. In some cases, MTC or IoT devices can be designed to support mission-critical functions, and the wireless communication system can be configured to provide ultra-reliable communication for these functions.

[0073] Base station 105 can communicate with core network 130 and with each other. For example, base station 105 can interface with core network 130 via backhaul link 132 (e.g., S1, etc.). Base station 105 can communicate with each other directly or indirectly (e.g., via core network 130) on backhaul link 134 (e.g., X2, etc.). Base station 105 can perform radio configuration and scheduling for communication with UE 115, or can operate under the control of a base station controller (not shown). In some examples, base station 105 can be a macro cell, small cell, hotspot, etc. Base station 105 can also be referred to as evolved Node B (eNB) 105.

[0074] Base station 105 can connect to core network 130 via the S1 interface. The core network may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may be a control node that handles signaling between UE 115 and the EPC. All user Internet Protocol (IP) packets can be transmitted through the S-GW, which itself can connect to the P-GW. The P-GW can provide IP address allocation and other functions. The P-GW can connect to network operator IP services. Operator IP services may include the Internet, intranets, IP Multimedia Subsystem (IMS), and packet-switched (PS) streaming services.

[0075] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the network devices (such as base station 105-a) may include sub-components such as access network entity 105-b, which may be an example of an access node controller (ANC). Each access network entity 105-b can communicate with multiple UEs 115 through multiple other access network transport entities 105-c (each of which may be an example of a smart radio headend or a transmit / receive point (TRP)). In some configurations, the various functions of each access network entity or base station 105 may be distributed across individual network devices (e.g., radio headends and access network controllers) or incorporated into a single network device (e.g., base station 105).

[0076] While the wireless communication system 100 can operate in the ultra-high frequency (UHF) frequency range using a band from 700 MHz to 2600 MHz (2.6 GHz), some networks (e.g., wireless local area networks (WLANs)) can use frequencies as high as 4 GHz. This area can also be referred to as the decimeter band because the wavelength range ranges in length from approximately one decimeter to one meter. UHF waves are primarily line-of-sight and can be blocked by buildings and environmental features. However, these waves can be sufficient to penetrate walls to provide service to the UE 115 located indoors. Compared to transmissions using the lower frequencies (and longer waves) of the high frequency (HF) or very high frequency (VHF) portions of the spectrum, UHF waves are characterized by smaller antennas and shorter distances (e.g., less than 100 km). In some cases, the wireless communication system 100 may also utilize the extremely high frequency (EHF) portion of the spectrum (e.g., from 30 GHz to 300 GHz). This area can also be referred to as the millimeter band because the wavelength range ranges in length from approximately one millimeter to one centimeter. Therefore, EHF antennas can be even smaller and more closely spaced compared to UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115 (e.g., for directional beamforming). However, EHF transmission may suffer from even greater atmospheric attenuation and shorter distances compared to UHF transmission.

[0077] Therefore, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105. Devices operating in the mmW or EHF band can have multiple antennas to allow beamforming. That is, the base station 105 can use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. Beamforming (which can also be referred to as spatial filtering or directional transmission) is a signal processing technique that can be used at a transmitter (e.g., base station 105) to beamform and / or direct the overall antenna beam towards the target receiver (e.g., UE 115). This can be achieved by combining elements in an antenna array in such a way that signals transmitted at a specific angle undergo constructive interference while other signals undergo destructive interference.

[0078] Multiple-input multiple-output (MIMO) wireless systems use a transmission scheme between a transmitter (e.g., base station 105) and a receiver (e.g., UE 115), where both the transmitter and receiver are equipped with multiple antennas. Some portions of the wireless communication system 100 may use beamforming. For example, base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use for beamforming in its communication with UE 115. Signals may be transmitted multiple times in different directions (e.g., beamforming may be applied to each transmission in different ways). The mmW receiver (e.g., UE 115) may attempt multiple beams (e.g., antenna subarrays) when receiving synchronization signals.

[0079] In some cases, the antennas of base station 105 or UE 115 may be located within one or more antenna arrays, which can support beamforming or MIMO operation. One or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with UE 115.

[0080] In some cases, the wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. In some cases, the Radio Link Control (RLC) layer may perform packet fragmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may also use Hybrid ARQ (HARQ) to provide retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide the establishment, configuration, and maintenance of RRC connections (supporting radio bearers for user plane data) between UE 115 and network devices 105-c, 105-b, or the core network 130. At the physical (PHY) layer, transport channels may be mapped to physical channels.

[0081] Time intervals in LTE or NR can be represented using multiples of a basic time unit (which can be a sampling period of Ts = 1 / 30,720,000 seconds). Time resources can be organized using radio frames of 10ms length (Tf = 307200Ts), identified by System Frame Numbers (SFNs) ranging from 0 to 1023. Each frame can include ten 1ms subframes numbered from 0 to 9. Subframes can be further divided into two .5ms slots, each containing 6 or 7 modulation symbol periods (depending on the length of the cyclic prefix added before each symbol). Excluding the cyclic prefix, each symbol contains 2048 sampling periods. In some cases, a subframe can be the minimum scheduling unit, also known as the TTI. In other cases, the TTI can be shorter than the subframe or can be dynamically selected (e.g., in short TTI bursts or in selected component carriers using short TTIs).

[0082] A resource element can include one symbol period and one subcarrier (e.g., a 15 kHz frequency range). A resource block can contain 12 consecutive subcarriers in the frequency domain and, for a normal cyclic prefix in each OFDM symbol, 7 consecutive OFDM symbols in the time domain (one timeslot), or 84 resource elements. The number of bits carried by each resource element can depend on the modulation scheme (the configuration of symbols that can be selected during each symbol period). Therefore, the more resource blocks the UE receives and the higher the modulation scheme, the higher the data rate can be.

[0083] The wireless communication system 100 can support operation on multiple cells or carriers (a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation). A carrier may also be referred to as a component carrier (CC), layer, channel, etc. The terms “carrier,” “component carrier,” “cell,” and “channel” are used interchangeably herein. The UE 115 can be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used in conjunction with both FDD and TDD component carriers.

[0084] In some cases, the wireless communication system 100 may utilize enhanced component carriers (eCC). eCC can be characterized by one or more features including: wider bandwidth, shorter symbol duration, shorter TTI, and a modified control channel configuration. In some cases, eCC may be associated with carrier aggregation or dual connectivity configurations (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). eCC can also be configured for use in unlicensed or shared spectrum (where more than one operator is permitted to use the spectrum). eCC characterized by wide bandwidth may include one or more segments that can be used by a UE 115 that cannot monitor the entire bandwidth or prefers to use limited bandwidth (e.g., to save power).

[0085] In some cases, eCC can utilize a different symbol duration than other CCs, which may include using a reduced symbol duration compared to other CCs. A shorter symbol duration is associated with increased subcarrier spacing. Devices utilizing eCC (such as UE 115 or base station 105) can transmit wideband signals (e.g., 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). The TTI in eCC can include one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in the TTI) can be variable.

[0086] Shared radio frequency spectrum bands can be utilized in NR shared spectrum systems. For example, in addition to this, NR shared spectrum can utilize any combination of licensed, shared, and unlicensed spectrum. The flexibility in eCC symbol duration and subcarrier spacing allows for the use of eCC across multiple spectrums. In some examples, NR shared spectrum can improve spectrum utilization and efficiency, especially through dynamic vertical (e.g., across frequencies) and horizontal (e.g., across time) sharing of resources.

[0087] In some cases, wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 may employ LTE Licensed Assisted Access (LTE-LAA) or LTE Unlicensed (LTE U) radio access technology or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, wireless devices (such as base station 105 and UE 115) may employ a Listen-Before-Speak (LBT) procedure to ensure the channel is idle before transmitting data. In some cases, operation in unlicensed frequency bands may be based on a CA configuration that combines CC (Carrier Component) for operation in licensed frequency bands. Operation in unlicensed spectrum may include downlink transmission, uplink transmission, or both. Duplexing in unlicensed spectrum may be based on Frequency Division Duplex (FDD), Time Division Duplex (TDD), or a combination of both.

[0088] In some cases, the LBT procedure for multi-carrier transmission (such as the described unpermitted UL (GUL) transmission) can be similar to or the same as the multi-carrier LBT procedure for a UE using LAA. In some examples, one or more LBT modes can be used for unpermitted UL. In some cases, unpermitted UL transmission can follow Wi-Fi channel bonding rules, for example, if operating in the 5 GHz radio frequency spectrum band. In examples of multi-carrier unpermitted UL transmission, different contention windows can be used for different CCs, and these contention windows can be updated separately or independently from other contention windows.

[0089] Base station 105 and UE 115 can support the coexistence of permissionless uplink transmission and permission-based uplink transmission. A radio device (e.g., base station 105 (or UE 115)) can identify a priority configuration for UE 115 (or base station 105, etc.), which UE 115 uses to prioritize autonomous UL transmissions between scheduled UL transmissions when operating in a power-constrained state. In some cases, autonomous UL transmissions will be sent on a first CC in a shared RF band, and scheduled UL transmissions will be sent on a second CC in a second RF band (e.g., a shared, licensed, or unlicensed RF band) during the same time period as the autonomous UL transmissions. Base station 105 (or UE 115) can then send a priority configuration (e.g., including priority information) to UE 115. UE 115 can schedule the first scheduled transmission and the second autonomous transmission on different channels during a subframe. Then, UE 115 can determine that it does not have sufficient power to transmit both the first scheduled transmission and the second autonomous transmission during that subframe. UE 115 can select one of the two transmissions based at least in part on priority information. For example, the priority information can instruct UE 115 (or base station 105) to prioritize the first scheduled transmission. UE 115 (or base station 105) can transmit the first scheduled transmission and can discard the second autonomous transmission or reschedule the second autonomous transmission for another subframe.

[0090] UE 115 can also identify autonomous UL transmissions to be sent on the first CC in a shared RF band during the time period. Then, UE 115 can, for example, during the same time period, send an indication to the base station in a power headroom report regarding whether UE 115 will attempt to send an autonomous UL transmission during the time period on the second CC in a second RF band (e.g., a shared, licensed, or unlicensed RF band). Base station 105 can determine whether the UE will attempt to transmit based on the power headroom report.

[0091] Figure 2 Examples of a wireless communication system 200 supporting the coexistence of autonomous uplink transmission and permitted uplink transmission according to various aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100.

[0092] The wireless communication system 200 may include a UE 205 and a base station 210. The UE 205 and base station 210 may be as described in reference... Figure 1 Examples of various aspects of the described UE 115 and base station 105.

[0093] The uplink communication path between UE 205 and base station 210 may include multiple channels (or component carriers) 215, each channel 215 covering a different, non-overlapping frequency band. Each channel 215 may be divided into multiple subframes. For example, each channel 215 may be time-divided into subframes 220. In other examples, channels 215 may be divided into different or additional types of time periods or durations besides subframes. For example, channels 215 may be divided into subframes, time slots, microslots, or symbols, or some combination of one or more of these.

[0094] Base station 210 may send one or more unpermitted uplink configuration messages to UE 205 in RRC signaling for configuring uplink (UL) channel 215. For example, the configuration information may identify the set of subframes in which unpermitted uplink transmissions can be sent. For example, the unpermitted UL configuration message may indicate that subframes 220-a, 220-b, 220-c, 220-d, 220-e, 220-f, and 220-g can be used to send scheduled uplink (SUL) transmissions on the first channel 215-a, and may indicate that subframes 220-h, 220-i, and 220-j can be used to send unpermitted UL transmissions on the first channel 215-a.

[0095] Base station 210 can also send a priority indicator to UE 205 in RRC signaling. When UE 205 has already scheduled both types of transmissions during the subframe, the priority indicator can indicate whether UE 205 should prioritize exempt UL transmissions or scheduled UL transmissions.

[0096] In some examples, base station 210 may send a configuration for all channels such that the configuration for the first channel 215-a can be used for all channels 215. In other examples, base station 210 may send two or more configurations. For example, an unpermitted UL configuration message may indicate that subframes 220-a, 220-b, and 220-c can be used to send scheduled UL transmissions on the second channel 215-b, and may indicate that subframes 220-d, 220-e, 220-f, 220-g, 220-h, 220-i, and 220-j can be used to send unpermitted UL transmissions on the second channel 215-b. UE 205 may configure its unpermitted UL transmissions at least in part based on one or more unpermitted UL configuration messages. In some examples, the configuration for unpermitted ULs and / or scheduled ULs and the transmission of unpermitted ULs and / or scheduled ULs may be for different types of time periods or durations than or other than subframes. For example, UE 205 can configure transmission on one or more channels 215 based on subframes, time slots, microslots or symbols, or some combination of one or more of subframes, time slots, microslots and symbols.

[0097] UE 205 may transmit one or more permissionless UL transmissions in a subframe. Before transmitting the permissionless UL transmission, UE 205 may perform a Listen-Before-Speak (LBT) procedure. For example, UE 205 may schedule a permissionless UL transmission on second channel 215-b during subframe 220-f. UE 205 may perform the LBT procedure on second channel 215-b during subframe 220-f (e.g., at the beginning of subframe 220-f). After successfully completing the LBT procedure, UE 205 may transmit the permissionless UL transmission.

[0098] UE 205 can perform a separate LBT procedure on each channel on which UE 205 expects to transmit during a subframe. For example, if UE 205 has permissionless UL transmissions scheduled on second channel 215-b and third channel 215-c during a second subframe, UE 205 can perform a first LBT procedure on second channel 215-b and a second LBT procedure on third channel 215-c. For example, when the LBT procedure involves the use of a contention window, a separate contention window can be used for each channel.

[0099] In some examples, UE 205 can schedule both unpermitted UL transmissions and scheduled UL transmissions within the same subframe (or time slot, micro-time slot, symbol, etc.). For example, UE 205 can schedule a scheduled UL transmission on the first channel 215-a during subframe 220-f and can schedule an unpermitted UL transmission on the second channel 215-b during subframe 220-f. UE 205 can transmit both scheduled UL transmissions and unpermitted UL transmissions within the same subframe. In some examples, UE 205 may not have sufficient power capacity to transmit both scheduled UL transmissions and unpermitted UL transmissions. In some examples, UE 205 can prioritize scheduled UL transmissions by dropping unpermitted UL transmissions. In some examples, UE 205 can prioritize either unpermitted UL transmissions or scheduled UL transmissions at least in part based on a priority indicator provided by base station 210.

[0100] In some examples, UE 205 may send a power headroom report to base station 210. For example, UE 205 may send a power headroom report periodically, or it may send a power headroom report at least in part based on a change in power (e.g., a change in path loss greater than a threshold). The power headroom report may include an indication of whether or not UE 205 will attempt to bypass UL transmission in the subframe in which it sends the power headroom report.

[0101] Figure 3 An example flowchart 300 of communication in a wireless communication system supporting the coexistence of autonomous uplink transmission and permitted uplink transmission, according to various aspects of this disclosure, is shown. In some examples, the wireless communication system may implement various aspects of wireless communication system 100.

[0102] Flowchart 300 illustrates the communication between base station 305 and UE 310. Base station 305 may be a reference Figure 1 Examples of various aspects of the described base station 105. UE 310 can be used as a reference. Figure 1 Examples of various aspects of UE 115 as described.

[0103] Base station 305 may send one or more permissionless (autonomous) UL configuration messages, such as RRC message 315, to UE 310. The RRC message may include configuration information for component carriers. The configuration information may identify subframes in which permissionless uplink transmissions can be transmitted (e.g., a set of subframes for permissionless UL transmissions). The configuration information may also identify subframes in which scheduled uplink transmissions can be transmitted.

[0104] In some examples, RRC message 315 may identify configuration information for each component carrier. In other examples, RRC message 315 may identify configuration information for a group of component carriers. In still other examples, RRC message 315 may identify configuration information applicable to all component carriers.

[0105] In some examples, RRC message 315 may identify one or more subframes on which permissionless uplink transmissions can be transmitted. In other examples, RRC message 315 may identify at least one component carrier on which no permissionless uplink transmission can be transmitted.

[0106] RRC message 315 may include a priority indicator. When both types of transmissions are scheduled for transmission within the same subframe, the priority indicator may indicate whether an unpermitted UL transmission or a scheduled UL transmission should be prioritized. In some examples, the priority indicator may be or include a metric for determining whether an unpermitted UL transmission or a scheduled UL transmission should be prioritized.

[0107] In some examples, RRC message 315 may also include a scrambling identifier, a MIMO indication, a maximum number of UL subframes to be exempted, a partial subframe indication, an end position indication, or a combination thereof.

[0108] At 320, UE 310 may configure unlicensed uplink transmission on one or more component carriers, at least in part, based on RRC message 315. The one or more component carriers may be in unlicensed or shared licensed radio frequency spectrum bands. For example, UE 310 may determine, at least in part, one or more subframes on one or more component carriers, on which UE 310 may attempt to transmit unlicensed uplink transmissions.

[0109] In some examples, UE 310 can also receive permissionless downlink control information (G-DCI). G-DCI can be transmitted in a basic format or an extended format. The extended format can be, for example, DCI format 1C. UE 310 can monitor G-DCI in the common search space of the primary cell (PCell). UE 310 can also, alternatively, monitor G-DCI in the common search space of the secondary cell (SCell).

[0110] At position 325, UE 310 can perform a Listen-Before-Speak (LBT) procedure. In some examples, UE 310 can search for a cell-specific reference signal (CRS) in the subframe. If UE 310 does not detect a CRS in the first symbol of the subframe, UE 310 can perform the LBT procedure in the following time period. Until UE 310 has successfully performed the LBT procedure, it may or may not be prohibited from transmitting permitted uplink transmissions.

[0111] The LBT procedure can be performed separately for each component carrier. Therefore, UE 310 can perform multiple LBT procedures during a subframe, with each LBT procedure performed on a different component carrier. In some examples, the LBT procedure may include the use of a contention window, and a separate contention window may be used for each component carrier.

[0112] UE 310 may transmit unlicensed UL transmission 330 at least in part based on an LBT procedure. UE 310 may transmit unlicensed UL transmission 330 to base station 305. UE 310 may transmit unlicensed UL transmission 330 on one or more component carriers in an unlicensed or shared frequency band. UE 310 may transmit unlicensed UL transmission 330 in a subframe of an LBT procedure performed therein.

[0113] The unpermitted UL transmission 330 may include a data portion. In some examples, the unpermitted UL transmission 330 may include an uplink control information (UCI) portion. The UCI portion may include modulation and coding scheme (MCS) information, scrambling information, Hybrid Automatic Repeat Request (HARQ) procedure information, or other information used to facilitate decoding of the data portion. The unpermitted UL transmission 330 may be transmitted based on probabilistic transmission parameters, Received Signal Strength Indicator (RSSI), traffic priority, or the state of the uplink buffer.

[0114] In some examples, base station 305 may send one or more acknowledgments (ACKs) or negative acknowledgments or no acknowledgments (NACKs or NAKs) in response to permissionless UL transmission 330. Each ACK or NACK may be transmitted on a component carrier of permissionless UL transmission 330 that carries the ACK or NACK in response.

[0115] Figure 4 An example flowchart 400 of communication in a wireless communication system supporting the coexistence of autonomous uplink transmission and permitted uplink transmission is shown, according to various aspects of this disclosure. In some examples, the wireless communication system may implement various aspects of wireless communication system 100.

[0116] Flowchart 400 illustrates the communication between UE 410 and base station 405. UE 410 can be a reference. Figure 1 Examples of various aspects of the described UE 115. Base station 405 can be used as a reference. Figure 1 Examples of various aspects of the described base station 105.

[0117] At 415, UE 410 can schedule permissionless UL transmissions on the first carrier in a subframe. UE 410 can schedule permissionless UL transmissions at least in part based on the configuration information provided in the RRC message.

[0118] At 420, UE 410 can schedule scheduled UL transmissions on the second carrier in a subframe. UE 410 can schedule scheduled UL transmissions at least in part based on scheduling information in the downlink control information (DCI) received from base station 405. That is, base station 405 can schedule UL resources for scheduled UL transmissions performed by UE 410, and the scheduling of scheduled UL transmissions performed by UE 410 is based on the scheduling information provided by base station 405 for the scheduled UL transmissions.

[0119] At 425, UE 410 can determine its power capacity for UL transmission. In some examples, UE 410 can determine that a power-constrained scenario exists, for example, in a power-constrained scenario, UE 410 cannot transmit both unpermitted UL transmission and scheduled UL transmission during the same subframe. In some examples, UE 410 can prioritize scheduled UL transmission over unpermitted UL transmission. In some other examples, UE 410 can prioritize unpermitted UL transmission over scheduled UL transmission. In some examples, UE 410 can determine which type of transmission to transmit, at least in part, based on a priority indicator. Base station 405 can, for example, refer to the above... Figure 3 The described RRC message sends a priority indicator to UE 410.

[0120] In some examples, UE 410 may prioritize one transmission type (e.g., scheduled UL transmission) over another transmission type (e.g., unpermitted UL transmission) by not transmitting the other transmission type (e.g., unpermitted UL transmission) during a subframe (or slot, microslot, or symbol). In other examples, UE 410 may prioritize one transmission type (e.g., scheduled UL transmission) over another transmission type (e.g., unpermitted UL transmission) by attempting to transmit the other transmission type (e.g., unpermitted UL transmission) when the prioritized transmission type (e.g., scheduled UL transmission) is not transmitted because UE 410 is unable to reserve medium (e.g., because the LBT procedure for transmitting the component carrier on which the scheduled UL transmission is to be transmitted is unsuccessful).

[0121] UE 410 may transmit scheduled UL transmission 430 and unapproved UL transmission 435 during a subframe. In some examples, UE 410 may transmit only the prioritized type (unapproved UL or scheduled UL) and discard the non-prioritized types (scheduled UL or unapproved UL, respectively), even when the type expected to be prioritized starts after the non-prioritized type. For example, a priority indicator may indicate that scheduled UL transmissions may take precedence over unapproved UL transmissions. In such examples, where a power-limited scenario exists, unapproved UL transmission 435 may not be transmitted during a subframe, even when unapproved UL transmission 435 is expected to start before scheduled UL transmission 430 in the subframe.

[0122] Figure 5 Examples of a power margin report 500, which can be used in a wireless communication system supporting both autonomous uplink transmission and permitted uplink transmission, are shown according to various aspects of this disclosure. In some examples, the wireless communication system may implement various aspects of wireless communication system 100.

[0123] The power headroom report 500 may be or include a power headroom medium access control (MAC) control element. The power headroom report 500 may include multiple fields, including a reserved field 505, a GUL field 510, and a power headroom field 515. The reporting device may periodically or non-periodically send the power headroom report 500 to the base station, for example, in response to a change in power (e.g., a change in path loss exceeding a threshold).

[0124] The power headroom field 515 can provide information about the power headroom of the reporting device. For example, the power headroom field 515 can indicate the headroom between the current transmission power of the reporting device and the nominal power of the reporting device. The base station can use the information in the power headroom field 515 to estimate how much uplink bandwidth the reporting device can use within a specific time period (e.g., a subframe). The power headroom field 515 can indicate the range within which the power headroom falls.

[0125] The GUL field 510 can indicate when the permissionless UL mode is active in a multi-carrier scenario. For example, the GUL field 510 can be a one-bit GUL flag, where "0" indicates that the reporting device will not attempt permissionless UL transmission in the subframe in which the power headroom report 500 is transmitted, and "1" indicates that the reporting device will attempt permissionless UL transmission in the subframe in which the power headroom report 500 is transmitted.

[0126] The reserved field 505 can be reserved for future deployment, or it can include other data related to the power margin of the device.

[0127] A power headroom report 500 can be sent from the UE to the base station in a subframe to which the power headroom field 515 applies. The power headroom report 500 can also be sent in a subframe on a component carrier different from the component carrier carrying the permitted UL transmission.

[0128] Figure 6 A block diagram 600 of a wireless device 605 supporting the coexistence of autonomous uplink transmission and permitted uplink transmission according to various aspects of this disclosure is shown. The wireless device 605 may be an example of various aspects of a user equipment (UE) 115 as described herein. The wireless device 605 may include a receiver 610, a UE communication manager 615, and a transmitter 620. The wireless device 605 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0129] Receiver 610 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to the coexistence of autonomous uplink transmission and permission-based uplink transmission in multi-carrier licensed assisted access). This information can be passed to other components of the device. Receiver 610 can be a reference... Figure 9 Examples of various aspects of the transceiver 935 are described. The receiver 610 can utilize a single antenna or a set of antennas.

[0130] Receiver 610 can receive scheduled UL transmissions in the second RF band on the first CC during a time period, the scheduled UL transmissions including power margin reports.

[0132] At least some of the sub-components of the UE communication manager 615 and / or its various sub-components can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functionality of at least some of the sub-components of the UE communication manager 615 and / or its various sub-components can be performed by a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described in this disclosure. At least some of the sub-components of the UE communication manager 615 and / or its various sub-components can be physically located in various locations, including being distributed such that portions of the functionality are implemented by one or more physical devices at different physical locations. In some examples, according to various aspects of this disclosure, at least some of the sub-components of the UE communication manager 615 and / or its various sub-components can be separate and distinct components. In other examples, at least some of the UE communication manager 615 and / or its various sub-components may be combined with one or more other hardware components (including, but not limited to, I / O components, transceivers, network servers, other computing devices, one or more other components described in this disclosure, or combinations thereof) in accordance with various aspects of this disclosure.

[0133] The UE communication manager 615 can perform the following operations: determine that the UE is operating in a power-constrained state; identify autonomous UL transmissions to be transmitted on the first CC in a shared radio frequency (RF) band during a time period; identify scheduled UL transmissions to be transmitted on the second CC in a second RF band during a time period; identify priority configurations for prioritizing autonomous UL transmissions versus scheduled UL transmissions for the power-constrained state; and transmit autonomous UL transmissions or scheduled UL transmissions to the base station based on the identified priority configurations. The UE communication manager 615 can also perform the following operations: identify autonomous UL transmissions to be transmitted on the first CC in a shared RF band during a time period; and transmit an indication in a power margin report during a time period on the second CC in the second RF band regarding whether the UE will attempt to transmit autonomous UL transmissions.

[0134] Transmitter 620 can transmit signals generated by other components of the device. In some examples, transmitter 620 can be co-located with receiver 610 in a transceiver module. For example, transmitter 620 can be a reference... Figure 9Examples of various aspects of the transceiver 935 are described. The transmitter 620 can utilize a single antenna or a set of antennas.

Alternatively, base station 105 may use dedicated hardware to perform aspects of the functions described below.

[0206] At block 1705, base station 105 may receive a power margin report from UE in the first CC within the second RF band during a time period. Operation of block 1705 can be performed according to the methods described herein. In some examples, aspects of operation of block 1705 may be derived from, as referenced... Figures 10 to 13 The described power margin report manager is used to perform this.

[0207] At block 1710, base station 105 can identify, at least in part, an indication regarding whether the UE will attempt to transmit autonomous UL transmissions on the second CC in the shared RF band, based on the received power margin report. Operation of block 1710 can be performed according to the methods described herein. In some examples, aspects of operation of block 1710 can be derived from, as referenced... Figures 10 to 13 The described transmission identifier is used to perform this action.

[0208] It should be noted that the methods described above describe possible implementations, and the operations and steps can be rearranged or otherwise modified, and other implementations are possible. Furthermore, aspects from two or more of these methods can be combined.

[0209] The techniques described in this article can be used in various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and others. The terms "system" and "network" are often used interchangeably. CDMA systems can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). CDMA2000 encompasses the IS-2000, IS-95, and IS-856 standards. Versions of IS-2000 are often referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is often referred to as CDMA2000 1xEV-DO, High-Speed ​​Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variations of CDMA. TDMA systems can implement radio technologies such as Global System for Mobile Communications (GSM).

[0210] OFDMA systems can implement radio technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Flash OFDM. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, NR, 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 technologies described herein can be used with the systems and radio technologies mentioned above, as well as other systems and radio technologies. While aspects of LTE or NR systems may be described for illustrative purposes, and the terminology of LTE or NR may be used in much of the description, the applications of the technologies described herein extend beyond LTE or NR.

[0211] In LTE / LTE-A networks (including those described herein), the term Evolved Node B (eNB) is often used to describe a base station. One or more wireless communication systems described herein may include heterogeneous LTE / LTE-A or NR networks, where different types of eNBs provide coverage for various geographic areas. For example, each eNB, Next-Generation Node B (gNB), or base station may provide communication coverage for macro cells, small cells, or other types of cells. The term "cell" may be used to describe a base station, a carrier or component carrier associated with a base station, or the coverage area of ​​a carrier or base station (e.g., a sector, etc.), depending on the context.

[0212] A base station may include, or may be referred to by those skilled in the art as, a base station transceiver, a wireless base station, an access point, a wireless transceiver, a Node B, an evolved Node B (eNB), a gNB, a home Node B, a home evolved Node B, or some other suitable term. The geographical coverage area of ​​a base station may be divided into sectors, each sector constituting only a portion of that coverage area. One or more wireless communication systems described herein may include different types of base stations (e.g., macro cell base stations or small cell base stations). The UE described herein may be able to communicate with various types of base stations and network devices (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.). Overlapping geographical coverage areas may exist for different technologies.

[0213] Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with service subscriptions to a network provider. In contrast, small cells are lower-power base stations that can operate in the same or different (e.g., licensed, unlicensed, etc.) frequency bands as macro cells. Depending on the examples, small cells can include picocells, femtocells, and microcells. For example, a picocell can cover a small geographic area and allow unrestricted access by UEs with service subscriptions to a network provider. A femtocell can also cover a small geographic area (e.g., a residential area) and provide restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in a residential area, etc.). An eNB used for a macro cell can be referred to as a macro eNB. An eNB used for a small cell can be referred to as a small cell eNB, pico eNB, femtocell eNB, or home eNB. An eNB can support one or more (e.g., two, three, four, etc.) cells (e.g., component carriers).

[0214] The one or more wireless communication systems described herein can support synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timings, and transmissions from different base stations can be approximately time-aligned. For asynchronous operation, base stations can have different frame timings, and transmissions from different base stations may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0215] The downlink transmissions described in this article can also be referred to as forward link transmissions, while the uplink transmissions can also be referred to as reverse link transmissions. Each communication link described in this article (including, for example) Figure 1 and Figure 2 The wireless communication systems 100 and 200 may include one or more carriers, wherein each carrier may be a signal composed of multiple subcarriers (e.g., waveform signals of different frequencies).

[0216] This document describes exemplary configurations with reference to the accompanying drawings, but does not represent all examples that can be implemented or that are within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration" and is not necessarily "preferred" or "advantageous over other examples." For the purpose of providing an understanding of the described techniques, the detailed description includes specific details. However, these techniques may be implemented without these specific details. In some instances, well-known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0217] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by a dash followed by a second reference numeral, used to differentiate between similar components. If only the first reference numeral is used in the specification, the description applies to any of the similar components having the same first reference numeral, regardless of the second reference numeral.

[0218] The information and signals described herein can be represented using any of a variety of different techniques and methods. For example, the data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or particles, light fields or particles, or any combination thereof.

[0219] The various illustrative boxes and modules described in connection with the disclosure herein can be implemented or executed using a general-purpose processor, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware component, or any combination thereof designed to perform the functions described herein. The general-purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration).

[0220] The functionality described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functionality can be stored as one or more instructions or code on or transmitted through a computer-readable medium. Other examples and implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functionality described above can be implemented using software executed by a processor, hardware, firmware, hardwired, or any combination of these. Features used to implement the functionality can also be physically located in various locations, including being distributed such that different parts of the functionality are implemented in different physical locations. Furthermore, as used herein (including in the claims), "or" as used in a list of items (e.g., a list of items ending with phrases such as "at least one of..." or "one or more of...") indicates an inclusive list, such that, for example, a list of at least one of A, B, or C means A, or B, or C, or AB, or AC, or BC, or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, without departing from the scope of this disclosure, an exemplary step described as "based on condition A" may be based on both condition A and condition B. In other words, as used herein, the phrase "based on" should be interpreted in the same way as the phrase "at least partially based on".

[0221] Computer-readable media includes both non-transitory computer storage media and communication media, wherein the communication media includes any medium that facilitates the transfer of a computer program from one place to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable read-only memory (EEPROM), compressed optical disc (CD) ROM or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium capable of carrying or storing desired units of program code in the form of instructions or data structures and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology (e.g., infrared, radio, and microwave), then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology (e.g., infrared, radio, and microwave) is included in the definition of media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs, where disks typically copy data magnetically, while optical discs use lasers to copy data optically. Combinations of these are also included within the scope of computer-readable media.

[0222] The description herein is provided to enable those skilled in the art to implement or use the present disclosure. Various modifications to the present disclosure will be apparent to those skilled in the art, and the general principles defined herein can be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not intended to be limited to the examples and designs described herein, but is to be given the widest scope consistent with the principles and novel features disclosed herein.
