[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to U.S. Provisional Application No. 62 / 860,430, filed on June 12, 2019, entitled “SUBBAND ​​BASED RESOURCE ALLOCATION FOR INTERLACED PUSCH,” and U.S. Non-Provisional Application No. 16 / 805,332, filed on February 28, 2020, entitled “TECHNIQUES FOR SUBBAND ​​BASED RESOURCE ALLOCATION FOR NR-U,” which are hereby expressly incorporated herein by reference. Technical Field

[0004] Aspects of the present disclosure relate generally to wireless communications and techniques for subband-based resource allocation for unlicensed new radio. Background Art

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0006] A wireless communication network may include several base stations (BS) that may support communications for several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0007] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at municipal, national, regional and even global levels. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR aims to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to increase, further improvements need to be made in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0068] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0069] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks using any suitable transmission network, etc.).

[0070] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0071] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0072] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. These BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0073] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle-mounted component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0074] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to a network (e.g., a wide area network, such as the Internet or a cellular network) or to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as user premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, etc.

[0075] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0076] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0077] As mentioned above, Figure 1 This is provided as an example only. Other examples may differ from those in combination with Figure 1 The content described.

[0078] Figure 2 Shows that it can be Figure 1 1. Block diagram of a design 200 of base station 110 and UE 120 for one of the base stations and one of the UEs in FIG. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0079] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for the UE based at least in part on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the one or more MCSs selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0080] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0081] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0082] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120 and / or Figure 2One or more other components of the base station 110 may perform one or more techniques associated with subband-based resource allocation for unlicensed new radio (NR-U), as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component or components may perform or direct e.g. Figure 6 The process of 600 Figure 7 The operations of process 700 and / or other processes described herein may be performed. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0083] In some aspects, the UE 120 may include: means for identifying a subband configuration of a plurality of subbands configured for the UE 120, the subband configuration including one or more guard bands of the plurality of subbands; means for identifying one or more resource blocks in which to send a PUSCH communication based at least in part on the subband configuration; means for sending the PUSCH communication in the one or more resource blocks to the base station 110, etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are described.

[0084] In some aspects, the base station 110 may include: means for configuring a subband configuration including one or more guard bands of a plurality of subbands configured to the UE 120; means for sending an indication of the subband configuration to the UE 120, etc. In some aspects, such means may include combining Figure 2 One or more components of base station 110 are described.

[0085] As mentioned above, Figure 2 These are provided as examples only. Other examples may differ from those described herein. Figure 2 The content described.

[0086] Figure 3A An example frame structure 300 for frequency division duplex (FDD) in a telecommunication system (e.g., NR) is shown. The transmission timeline of each of the downlink and uplink may be divided into radio frame (sometimes referred to as frame) units. Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., Figure 3A Each subframe 2 is shown mtime slots, where m is the number of symbols used for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a group of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices 0 to 2L-1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, symbol-based, etc.

[0087] Although some techniques are described herein in conjunction with frames, subframes, time slots, etc., these techniques may be equally applicable to other types of wireless communication structures, which may be referred to in 5G NR using terms other than "frames," "subframes," "time slots," etc. In some aspects, a wireless communication structure may refer to a periodic, time-bounded communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, a wireless communication structure may be used in conjunction with a wireless communication standard and / or protocol. Figure 3A The wireless communication structure configurations are different from those shown in FIG.

[0088] In some telecommunications (e.g., NR), a base station may send synchronization signals. For example, a base station may send a primary synchronization signal (PSS), a secondary synchronization signal (SSS), etc. on the downlink of each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, and the SSS may be used by the UE to determine the physical cell identifier associated with the base station and the frame timing. The base station may also send a physical broadcast channel (PBCH). The PBCH may carry some system information, such as system information that supports initial access of the UE.

[0089] In some aspects, the base station may send the PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., SS level) including multiple synchronization communications (e.g., synchronization signal (SS) blocks), as described below in conjunction with Figure 3B Described.

[0090] Figure 3B is a block diagram conceptually illustrating an example SS hierarchy, which is an example of a synchronous communication hierarchy. Figure 3B As shown in , the SS level may include an SS burst set, which may include multiple SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of the SS burst that can be sent by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b max_SS-1 ), where bmax_SS -1 is the maximum number of SS blocks that can be carried by an SS burst). In some aspects, different SS blocks may be beamformed in different ways. SS burst sets may be sent by a wireless node periodically, such as every X milliseconds, e.g. Figure 3B In some aspects, the SS burst set can have a fixed or dynamic length. Figure 3B is shown as Y milliseconds.

[0091] Figure 3B The SS burst set shown in is an example of a synchronous communication set, and other synchronous communication sets may be used in conjunction with the techniques described herein. Figure 3B The SS blocks shown in are examples of synchronous communications, and other synchronous communications may be used in conjunction with the techniques described herein.

[0092] In some aspects, an SS block includes resources that carry PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and the PSS, SSS, and / or PBCH may be identical for each SS block across an SS burst. In some aspects, a single SS block may be included in an SS burst. In some aspects, an SS block may be at least four symbol periods in length, with each symbol carrying one or more of a PSS (e.g., occupying one symbol), a SSS (e.g., occupying one symbol), and / or a PBCH (e.g., occupying two symbols).

[0093] In some aspects, the symbols of the SS block are coherent, such as Figure 3B In some aspects, the symbols of the SS blocks are non-contiguous. Similarly, in some aspects, one or more SS blocks of an SS burst may be sent in contiguous radio resources (e.g., contiguous symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks of an SS burst may be sent in non-contiguous radio resources.

[0094] In some aspects, an SS burst may have a burst periodicity, whereby the SS blocks of the SS burst are sent by the base station according to the burst periodicity. In other words, the SS blocks may be repeated during each SS burst. In some aspects, an SS burst set may have a burst set periodicity, whereby each SS burst of the SS burst set is sent by the base station according to a fixed burst set periodicity. In other words, the SS burst may be repeated during each SS burst set.

[0095] The base station may send system information, such as system information blocks (SIBs), on a physical downlink shared channel (PDSCH) in certain time slots. The base station may send control information / data on a physical downlink control channel (PDCCH) in C symbol periods of a time slot, where B may be configurable for each time slot. The base station may send traffic data and / or other data on the PDSCH in the remaining symbol periods of each time slot.

[0096] As mentioned above, Figure 3A and Figure 3B are provided as examples. Other examples may differ from combining Figure 3A and Figure 3B The content described.

[0097] Figure 4 An example slot format 410 with a normal cyclic prefix is ​​shown. Available time-frequency resources may be partitioned into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in one slot and may include a number of resource elements. Each resource element may cover one subcarrier in one symbol period (e.g., in time) and may be used to send one modulation symbol, which may be a real value or a complex value.

[0098] For FDD in some telecommunication systems (e.g., NR), an interleaving structure may be used for each of the downlink and uplink. For example, a Q interleaving with an index of 0 to Q-1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interleaving may include time slots spaced apart by Q frames. Specifically, interleaving q may include time slots q, q+Q, q+2Q, etc., where q∈{0,...,Q-1}. As another example, R interleaving may be defined, where R may be equal to 5, 10, or some other value based at least in part on the subcarrier spacing of the time slot format 410 (e.g., 5 for 30KHz subcarrier spacing, 10 for 15KHz subcarrier spacing, etc.). Each interleaving may include a resource block for PUSCH transmission, which is spaced apart by R resource blocks in the frequency domain. Specifically, interleaving r may include resource blocks r, r+R, r+2R, etc., where r∈{0,...,R-1}. As an example, for 5 interleavings of resource blocks, the first interleaving may include resource blocks 0, 5, 10, 15, etc., the second interleaving may include resource blocks 1, 6, 11, 15, etc., the third interleaving may include resource blocks 2, 7, 12, 16, etc.

[0099] A UE may be located within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected based at least in part on various criteria such as received signal strength, received signal quality, path loss, etc. The received signal quality may be quantified by a signal to interference plus noise ratio (SINR) or a reference signal received quality (RSRQ) or some other metric. The UE may operate in a strong interference scenario, in which the UE may observe severe interference from one or more interfering BSs.

[0100] Although aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be suitable for use with other wireless communication systems. A new radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., an air interface different from an orthogonal frequency division multiple access (OFDMA)-based air interface) or a fixed transport layer (e.g., different from the Internet Protocol (IP)). In various aspects, NR may utilize OFDM with CP (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplex (TDD). In various aspects, NR may utilize OFDM with CP (referred to herein as CP-OFDM) and / or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technologies, and / or mission critical services targeting ultra-reliable low latency communications (URLLC) services.

[0101] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 milliseconds (ms). Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., DL or UL) for data transmission, and the link direction of each slot may be switched dynamically. Each slot may include DL / UL data and DL / UL control data.

[0102] Beamforming can be supported and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. MIMO configuration in DL can support up to 8 transmit antennas (with up to 8 streams and multi-layer DL transmission of up to 2 streams per UE). Multi-layer transmission of up to 2 streams per UE can be supported. Aggregation of multiple cells can be supported using up to 8 serving cells. Alternatively, NR can support different air interfaces other than OFDM-based interfaces. NR networks can include entities such as central units or distributed units.

[0103] As mentioned above, Figure 4 These are provided as examples only. Other examples may differ from those described herein. Figure 4 The content described.

[0104] As described above, various interlaces of resource blocks for PUSCH transmissions may be defined for various types of wireless network deployments (e.g., 5G / NR deployments). In some cases, the resource blocks included in the interlace may be dispersed across multiple frequency domain resources (e.g., subbands, channels, etc.). In this case, the UE may identify resource blocks that may be used to send PUSCH communications to the BS based at least in part on the frequency domain resource allocation assigned to the UE and the interlace assigned to the UE. In other words, the UE may identify resource blocks included in the allocated interlace that fall into the subband or channel of the frequency domain resource allocation assigned to the UE.

[0105] In some cases, the subbands and associated guard bands that may be allocated to a UE may be included in a well-defined structure (e.g., length and position), such as for 5G / NR deployments in licensed bands. However, for NR-U deployments, subband and guard band lengths (e.g., in resource blocks) and / or positions may be based at least in part on unlicensed and / or shared bands used in the deployment, may be based at least in part on the channelization of another type of wireless access method (e.g., Wi-Fi channelization), may be based at least in part on interference requirements for unlicensed bands, may be dynamic and / or configurable by a BS in the deployment, etc. As a result, the UE may be unable to determine the length and / or position of the subbands and / or guard bands allocated to the UE's frequency-domain resource allocation, which in turn may cause the UE to be unable to identify resource blocks that may be used to send physical uplink shared channel (PUSCH) communications.

[0106] Some aspects described herein provide techniques and apparatus for subband-based resource allocation for NR-U. A UE may identify one or more resource blocks in which a PUSCH communication is to be sent based at least in part on a subband configuration of a plurality of subbands configured for the UE. The subband configuration may indicate and / or include one or more guard bands of a plurality of subbands allocated to the UE, as well as other parameters of the plurality of subbands and / or the one or more guard bands. The subband configuration may be hard-coded or system-wide configured for all subbands across a specific frequency band (e.g., an unlicensed frequency band in an NR-U deployment) or all frequency bands included in a wireless network, may be configured for all subbands on a cell basis for each BS in the wireless network, may be configured for each bandwidth part (BWP) associated with the BS, may be configured for different combinations of subbands, and the like. In this way, the UE is allowed to use the subband configuration to identify the length and / or position of the subband and / or guard band of the frequency domain resource allocation allocated to the UE (e.g., in an unlicensed frequency band deployment), which in turn allows the UE to identify the resource blocks that can be used to send PUSCH communications.

[0107] Figure 5A-5E is a diagram illustrating one or more examples 500 of subband-based resource allocation for NR-U according to various aspects of the present disclosure. Figure 5A-5E As shown, example 500 may include communications between a BS (eg, BS 110) and a UE (eg, UE 120). In some aspects, the BS and the UE are included in a wireless network (eg, wireless network 100).

[0108] In some aspects, the BS and UE may be configured to communicate in a wireless network using various frequency bands, such as one or more licensed frequency bands, one or more unlicensed and / or shared frequency bands, etc. Examples of unlicensed and / or shared frequency bands may include industrial, scientific, and medical (ISM) radio frequency bands, such as 2.4 GHz and 5 GHz (which may be typically used for Wi-Fi communications), etc. In order to allow cellular communications using unlicensed and / or shared frequency bands, the unlicensed and / or shared frequency bands may be configured as sub-bands. The sub-bands may be guard bands to provide some protection against radio frequency (RF) interference caused by transmissions in adjacent sub-bands.

[0109] In some aspects, the subband configuration may be hard-coded or system-wide configured for the entire unlicensed and / or shared bands for all BSs in the wireless network, may be hard-coded or system-wide configured for all unlicensed and / or shared bands permitted to operate in the wireless network, etc. The subband configuration may include, specify, and / or indicate one or more subbands, one or more guard bands associated with each subband (e.g., the location of the one or more guard bands, the length or bandwidth of the one or more guard bands, etc.), etc. The subband configuration may indicate the number of resource blocks included in each subband, may indicate the location of the one or more subbands (e.g., the starting resource block and the ending resource block of each subband), etc. The subband configuration may indicate the number of resource blocks included in each guard band, may indicate the location of the one or more guard bands (e.g., the starting resource block and the ending resource block of each guard band), etc.

[0110] The subband configuration may be hard-coded or system-wide configured for the entire unlicensed and / or shared bands for all BSs in the wireless network, such that the subband configuration configures all subbands and guard bands for the unlicensed and / or shared bands. In this case, all BSs in the wireless network may use the same subband configuration for the unlicensed and / or shared bands. As another example, the subband configuration may be hard-coded or system-wide configured for all unlicensed and / or shared bands for all BSs in the wireless network, such that the subband configuration configures all subbands and guard bands for all unlicensed and / or shared bands in the wireless network. In this case, all BSs in the wireless network may use the same subband configuration for all unlicensed and / or shared bands allowed to operate in the wireless network.

[0111] In some aspects, the sub-band configuration may be hard-coded or system-wide configured across the entire wireless network, for example, where a channel structure configured for other types of communications (e.g., Wi-Fi communications) is reused for cellular communications on unlicensed and / or shared bands. For example, if a BS and a UE communicate via 5 GHz, the BS and the UE (as well as other BSs and UEs in the wireless network) may reuse channels (e.g., channel frequencies and bandwidths) and guard bands configured for Wi-Fi communications as sub-bands and guard bands for cellular communications using the 5 GHz band. Examples of channel bandwidths for unlicensed and / or shared band channels may include 20 MHz, 80 MHz, 100 MHz, etc.

[0112] like Figure 5AAs shown in and by reference numeral 502, in some aspects, in addition to and / or in lieu of a subband configuration that is hard-coded or system-wide configured for the entire wireless network, the BS can configure a subband configuration based on a cell (e.g., a subband configuration that is specific to a cell), a subband configuration based on a BWP (e.g., a subband configuration that is specific to a BWP of a cell), a subband configuration based on a subband combination (e.g., a subband configuration that is specific to a combination of subbands of unlicensed and / or shared frequency bands), etc. In this manner, the BS (and other BSs in the wireless network) is allowed to flexibly configure subband configurations (e.g., the same subband configuration, different subband configurations, etc.) for different cells of the BS, different BWPs for each cell, different combinations of subbands in each cell, etc.

[0113] In some aspects, the BS may configure one or more combinations of subband configuration types for one or more UEs. For example, in addition to a hard-coded or system-wide subband configuration, the BS may configure a cell-based subband configuration, a BWP-based subband configuration, and / or a subband combination-based subband configuration for one or more UEs. In this case, the one or more UEs may use the hard-coded or system-wide subband configuration before RRC configuration by the BS, and may use the cell-based subband configuration, the BWP-based subband configuration, and / or the subband combination-based subband configuration after RRC configuration. As another example, the BS may configure a cell-based subband configuration, which may be configured for one or more UEs to be used as a default or baseline subband configuration (e.g., and thus may be sent in a SIB and / or another type of system information), and then the UE may perform RRC configuration using a UE-specific subband configuration (e.g., a BWP-based subband configuration, a subband combination-based subband configuration, etc.).

[0114] Figure 5B An example of a cell-based subband configuration is shown. Other cell-based subband configurations may be implemented. Figure 5B As shown, the cell-based subband configuration can configure multiple subbands (e.g., subbands B1-B5) and multiple associated guard bands (e.g., guard bands A1-A5) for unlicensed and / or shared frequency bands operating in a cell associated with the BS. In some aspects, the BS can define multiple subbands and multiple guard bands starting from a reference frequency or physical resource block of the unlicensed and / or shared frequency band (e.g., corresponding starting resource blocks and corresponding ending blocks of the multiple subbands and multiple guard bands). The reference frequency or physical resource block can be referred to as a common reference point or point A.

[0115] In some aspects, the configuration of multiple subbands and multiple guard bands in a subband configuration may be applied to all BWPs configured by a BS in a cell. Figure 5BVarious exemplary BWPs (eg, BWPs 0-2) configured for a BS are illustrated. Figure 5B As shown, BWP 0 may include subband B2 and guard bands A2 and A3 from the cell-based subband configuration, BWP 1 may include subbands B2 and B3 and guard bands A2-A4 from the cell-based subband configuration, BWP 2 may include subbands B1-B5 and guard bands A1-A5 from the cell-based subband configuration, and so on.

[0116] In addition, if Figure 5B As shown, the length and position of the subband and guard band in each BWP can be inherited from the cell-based subband configuration. In other words, the length and position of subband B2 can be the same for BWP 0, BWP 1, and BWP 2; the length and position of guard band A2 can be the same for BWP0, BWP 1, and BWP 2; and so on.

[0117] Figure 5C An example of a BWP-based subband configuration is shown. Other BWP-based subband configurations may be implemented. Figure 5C As shown, the BWP-based subband configuration can configure multiple BWPs for a cell associated with the BS. Each BWP can be configured with one or more subbands and one or more associated guard bands for unlicensed and / or shared bands operating in the cell associated with the BS. In some aspects, the BWP-based subband configuration can configure a single BWP. In this case, the BS can configure a corresponding BWP-based subband configuration for each BWP associated with the BS. In some aspects, the BWP-based subband configuration can configure one or more BWPs assigned to a UE. In this case, the BS can configure a corresponding BWP-based subband configuration for each UE that is connected to the BS for communication.

[0118] In some aspects, the configuration of the subbands and guard bands in the subband configuration of each BWP can be the same configuration or different configurations. In this case, one or more of the subbands B1-B5 in the first BWP can have different lengths and / or be located at different locations in the unlicensed and / or shared band relative to one or more of the subbands B1-B5 in the second BWP, or can have the same length and / or location as one or more of the subbands B1-B5 in the second BWP. Similarly, one or more of the guard bands A1-A6 in the first BWP can have different lengths and / or be located at different locations in the unlicensed and / or shared band relative to one or more of the guard bands A1-A6 in the second BWP, or can have the same length and / or location as one or more of the guard bands A1-A6 in the second BWP.

[0119] For example, Figure 5CVarious exemplary BWPs (eg, BWP 0-2) configured for a BS are illustrated. The BWPs may be configured in corresponding BWP-based subband configurations or in the same BWP-based subband configuration. Figure 5C As shown, BWP 0 may include subband B1 and guard bands A1 and A2, BWP1 may include subbands B1 and B1 and guard bands A1-A3, BWP 2 may include subbands B1-B5 and guard bands A1-A6, etc. Furthermore, the positions of subbands B1 and B2 may differ across BWPs 0-2, the positions of guard bands A1-A3 may differ across BWPs 0-2, and so on.

[0120] Figure 5D An example of a subband configuration based on subband combination is shown. Other subband configurations based on subband combination may be implemented. Figure 5D As shown, the subband configuration based on subband combinations can be associated with multiple subband combinations associated with the BS. Each subband combination can be configured with one or more subbands and one or more associated guard bands for unlicensed and / or shared frequency bands operated by the BS.

[0121] In some aspects, the subband configuration based on the subband combination may configure a single subband combination. In this case, the BS may configure a corresponding subband configuration based on the subband combination for each subband combination associated with the BS. In some aspects, the subband configuration based on the subband combination may configure one or more subband combinations assigned to the UE. In this case, the BS may configure a corresponding subband configuration based on the subband combination for each UE in communication connection with the BS. In some aspects, the subband configuration based on the subband combination for the subband combination may be the same or different for different BWPs associated with the BS, may be the same or different for different cells associated with the BS, etc.

[0122] In some aspects, the subbands included in the subband combination may be adjacent and / or continuous subbands. In this case, the subband configuration based on the subband combination may indicate and / or specify the start RB and the end RB of the continuous subband set. In some aspects, the subbands included in the subband combination may be non-adjacent subbands. In this case, the subband configuration based on the subband combination may indicate and / or specify the corresponding start RB and the corresponding end RB for each subband.

[0123] In some aspects, the configuration of the subbands and guard bands of each subband combination can be the same configuration or a different configuration. In this case, one or more of the subbands B1-B5 in the first subband combination can have different lengths and / or be located at different locations in the unlicensed and / or shared band relative to one or more of the subbands B1-B5 in the second subband combination, or can have the same length and / or location as one or more of the subbands B1-B5 in the second subband combination. Similarly, one or more of the guard bands A1-A6 in the first subband combination can have different lengths and / or be located at different locations in the unlicensed and / or shared band relative to one or more of the guard bands A1-A6 in the second subband combination, or can have the same length and / or location as one or more of the guard bands A1-A6 in the second subband combination.

[0124] For example, Figure 5D Various exemplary subband combinations configured for a BWP (eg, BWP 1) of a BS are illustrated. The subband combinations may be configured with corresponding subband configurations based on subband combinations or the same subband configurations based on subband combinations. Figure 5D As shown, each sub-band combination may include sub-band B1 and guard bands A1 and A2. Figure 5D As shown, the length and / or position of the sub-band B1 and / or the guard bands A1 and A2 may be the same or different in the sub-band combination.

[0125] like Figure 5E As shown, by reference numeral 504, the BS may send an indication of resource allocation to the UE. The resource allocation may indicate time domain resources (e.g., time slots, symbols, etc.) and / or frequency domain resources allocated to the UE. The frequency domain resources may include a BWP, one or more subbands included in the BWP, etc., which are included in a licensed or unlicensed and / or shared frequency band. In addition, the BS may send an indication of the interleaving of the resource blocks allocated to the UE.

[0126] In addition, the BS may send an indication of a subband configuration for one or more subbands assigned to the UE. The BS may send an indication of the subband configuration based at least in part on resource allocation, based at least in part on a hard-coded or system-wide subband configuration that is not configured for the wireless network, and the like. The subband configuration may include, indicate, and / or specify the length, position, and / or other parameters of one or more subbands assigned to the UE, and the length, position, and / or other parameters of one or more guard bands associated with the subbands assigned to the UE, and the like. As described above, the subband configuration may be a cell-based subband configuration, a BWP-based subband configuration, a subband combination-based subband configuration, and the like.

[0127] In some aspects, the BS may send an indication of resource allocation, an indication of interleaving, and / or an indication of subband configuration to the UE in one or more communications. The one or more communications may include a master information block (MIB), a SIB, a remaining minimum system information (RMSI) communication, an other system information (OSI) communication, a downlink control information (DCI) communication, a radio resource control (RRC) communication, a PBCH communication, a PDCCH communication, and / or another type of downlink communication. In some aspects, if the subband configuration is a cell-based subband configuration, the BS may send an indication of the subband configuration in a cell configuration for the cell. In some aspects, if the subband configuration is a BWP-based subband configuration, the BS may send an indication of the subband configuration in a BWP configuration for the BWP.

[0128] In some aspects, the BS may configure multiple candidate subband configurations in one or more first communications (e.g., MIB, SIB, RMSI communication, OSI communication, RRC communication, etc.), and the BS may send an indication of the subband configuration in one or more second communications (e.g., media access control (MAC) control element (MAC-CE) communication, DCI communication, etc.), where the one or more second communications index into the multiple candidate subband configurations indicated in the one or more first communications.

[0129] like Figure 5E As further shown in and by reference numeral 506, the UE may identify one or more resource blocks for sending PUSCH communications to the BS. In some aspects, the UE may identify the one or more resource blocks based at least in part on the resource allocation, subband configuration, and / or interleaving. For example, the UE may identify a first plurality of resource blocks included in a subband assigned to the UE based at least in part on the resource allocation and subband configuration, may identify a second plurality of resource blocks for interleaved PUSCH transmissions based at least in part on the interleaving, and may identify a subset of the resource blocks included in the first plurality of resource blocks and the second plurality of resource blocks as one or more resource blocks that the UE may use to send PUSCH communications. As shown in FIG. Figure 5E As further shown in and by reference numeral 508, the UE may send a PUSCH communication to the BS in one or more resource blocks identified as allowed for sending PUSCH communications to the BS.

[0130] In this manner, a UE may identify one or more resource blocks in which a PUSCH communication is to be sent based at least in part on a subband configuration of a plurality of subbands configured for the UE. The subband configuration may indicate and / or include one or more guard bands of a plurality of subbands assigned to the UE, and other parameters of the plurality of subbands and / or the one or more guard bands. The subband configuration may be hard-coded for all subbands across a particular frequency band (e.g., an unlicensed frequency band in an NR-U deployment) or for all frequency bands included in a wireless network, may be configured for all subbands on a cell basis for each BS in the wireless network, may be configured based on each BWP associated with the BS, may be configured for different subband combinations, and the like. In this way, the UE is allowed to use the subband configuration to identify the length and / or position of the subband and / or guard band of the frequency domain resource allocation assigned to the UE (e.g., in an unlicensed frequency band deployment), which in turn allows the UE to identify resource blocks that may be used to send PUSCH communications.

[0131] As mentioned above, Figure 5A-5E Provided as one or more examples. Other examples may differ from the Figures 5A-5E as described.

[0132] Figure 6 6 is a diagram illustrating an exemplary process 600, performed, for example, by a UE, in accordance with various aspects of the present disclosure.

The apparatus 802 may be a UE (eg, UE 120). In some aspects, the apparatus 802 includes a receiving component 804, an identifying component 806, and a sending component 808.
