Technical Field

[0003]

[0006] Generally speaking, aspects of the present disclosure relate to wireless communications and to techniques and apparatus for bandwidth part (BWP) operation for single downlink control information (DCI) multi-cell scheduling. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting 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).

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipment (UEs). The UEs can communicate with the BSs via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UEs, and an "uplink" (or "reverse link") refers to the communication link from the UEs to the BSs. As will be described in greater 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.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, and even global level. NR (which may also be referred to as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a 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), thereby better supporting mobile broadband Internet access, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other wireless access technologies remain useful. Summary of the Invention

[0037] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. More precisely, these aspects are provided so that the present disclosure will be comprehensive and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should recognize that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether that aspect is implemented independently of any other aspect of the disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be practiced. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using other structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0038] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by means of various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0039] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0040] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among others. The wireless network 100 may include a plurality of base stations 110 (illustrated as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), and the like. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of a BS and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0041] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 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.

[0042] In some aspects, cells may not necessarily be stationary, and the geographic area of a cell may move depending on the location of a mobile BS. In some aspects, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections using any suitable transport network or virtual networks).

[0043] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.

[0044] 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 impacts 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).

[0045] The network controller 130 may be coupled to a group of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate directly or indirectly with each other via a wireless or wired backhaul.

[0046] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), an in-vehicle 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.

[0047] Some UEs may be considered 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, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to or to a network (e.g., a wide area network such as the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0048] In general, 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.

[0049] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 can 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), mesh networks. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0050] Devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) (which can span from 410 MHz to 7.125 GHz) and / or can communicate using an operating band having a second frequency range (FR2) (which can span from 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are sometimes referred to as intermediate frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless expressly stated otherwise, it should be understood that the terms “sub-6 GHz,” etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequencies (e.g., greater than 7.125 GHz). Similarly, unless expressly stated otherwise, it should be understood that the terms “millimeter wave,” etc., if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

[0051] As pointed out above, Figure 1 is provided as an example. Other examples may differ from those described in relation to Figure 1 Examples described.

[0052] Figure 2is a diagram illustrating an example of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. 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.

[0053] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and frequency upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0054] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if 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 term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0055] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0056] The antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as Figure 2 One or more antenna elements of one or more components).

[0057] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any method described herein (e.g., as described with reference to FIG. Figure 3-10 description).

[0058] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120.

Base station 110 may include and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any method described herein (e.g., as described with reference to FIG. Figure 3-10 description).

[0059] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components in the may perform one or more techniques associated with bandwidth part (BWP) operation for single downlink control information (DCI) multi-cell scheduling, as described in more detail elsewhere herein.

For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process of 800 Figure 9 The process of 900 Figure 10 The operations of process 1000 and / or other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0060] In some aspects, the UE 120 may include: means for receiving DCI that schedules a first communication on a first bandwidth part and a second communication on a second bandwidth part; means for determining one or more parameters for the first bandwidth part and the second bandwidth part based at least in part on the DCI and in accordance with a bandwidth part configuration for the virtual bandwidth part; means for performing the first communication and the second communication based at least in part on the one or more parameters; means for receiving DCI indicating a bandwidth part configuration for the virtual bandwidth part before receiving the DCI that schedules the first communication and the second communication; means for receiving configuration information indicating a mapping between a bandwidth part index field of the virtual bandwidth part and bandwidth part indexes of the first bandwidth part and the second bandwidth part; means for receiving a second DCI that indicates switching the first bandwidth part from a first bandwidth part having a first index to a second bandwidth part having a second index; means for determining a configuration for the first bandwidth part based at least in part on the second bandwidth part index and a corresponding bandwidth part configuration associated with the virtual bandwidth part; means for determining a configuration for the first bandwidth part based at least in part on the second bandwidth part index and a corresponding bandwidth part configuration associated with the first bandwidth part; and means for switching the first bandwidth part based at least in part on the second DCI. means for receiving a physical downlink control channel (PDCCH) on a second serving cell of the UE, wherein the PDCCH includes a DCI having first control information for the first serving cell of the UE and second control information for the second serving cell of the UE; means for communicating on the first bandwidth part associated with the first serving cell and the second bandwidth part associated with the second serving cell according to the DCI; means for receiving configuration information indicating a mapping between bandwidth part index fields of the first control information and the second control information and bandwidth part indices of the first bandwidth part and the second bandwidth part; means for receiving a second DCI indicating switching the first bandwidth part from the first bandwidth part index to the second bandwidth part index; means for determining a configuration for the first bandwidth part based at least in part on the second bandwidth part index and a corresponding bandwidth part configuration associated with the first bandwidth part; means for switching the first bandwidth part and the second bandwidth part based at least in part on the second DCI, such that the same search space set identifier is associated with the first bandwidth part and the second bandwidth part after performing the handover; and the like. In some aspects, such a unit may include a combination of Figure 2One or more components of the UE 120 are depicted, such as a controller / processor 280, a transmit processor 264, a TX MIMO processor 266, a MOD 254, antennas 252, a DEMOD 254, a MIMO detector 256, a receive processor 258, and the like.

[0061] In some aspects, the base station 110 may include: means for sending a DCI that schedules a first communication on a first bandwidth part and a second communication on a second bandwidth part, wherein the DCI indicates one or more parameters for the first bandwidth part and the second bandwidth part based on a bandwidth part configuration for the virtual bandwidth part; means for performing the first communication and the second communication based at least in part on the one or more parameters; means for sending a DCI indicating the bandwidth part configuration for the virtual bandwidth part before sending the DCI that schedules the first communication and the second communication; means for sending configuration information indicating a mapping between a bandwidth part index field of the virtual bandwidth part and bandwidth part indices of the first bandwidth part and the second bandwidth part; means for sending a second DCI that indicates switching the first bandwidth part from the first bandwidth part index to the second bandwidth part index; and means for switching the first bandwidth part and the second bandwidth part based at least in part on the second DCI such that the same search space set is used after performing the switching. a unit for associating identifiers with first bandwidth parts and second bandwidth parts; a unit for sending a PDCCH on a second serving cell of a UE, wherein the PDCCH includes a DCI having first control information for the first serving cell of the UE and second control information for the second serving cell of the UE; a unit for communicating on the first bandwidth part associated with the first serving cell and the second bandwidth part associated with the second serving cell according to the DCI; a unit for sending configuration information indicating a mapping between bandwidth part index fields of the first control information and the second control information and bandwidth part indices of the first bandwidth part and the second bandwidth part; a unit for sending a second DCI indicating switching the first bandwidth part from the first bandwidth part index to the second bandwidth part index; a unit for switching the first bandwidth part and the second bandwidth part based at least in part on the second DCI such that the same search space set identifier is associated with the first bandwidth part and the second bandwidth part after performing the switching; and the like. In some aspects, such a unit may include a combination of Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0062] Although Figure 2The blocks in FIG. 2 are shown as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0063] As pointed out above, Figure 2 is provided as an example. Other examples may differ from those described in relation to Figure 2 Examples described.

[0064] Dynamic spectrum sharing (DSS) enables the use of multiple radio access technologies (RATs), such as LTE and 5G, in parallel in the same frequency band. For example, the network can independently divide the available bandwidth of the frequency band for LTE and 5G based at least in part on the demand for each of these RATs. DSS provides a mechanism for cross-carrier scheduling, where a single component carrier (CC) can schedule communications on multiple CCs. In some aspects, the PDCCH of a serving cell can carry DCI that schedules communications (e.g., PDSCH or PUSCH) on another serving cell in addition to scheduling the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) on the serving cell or without scheduling the PDSCH or PUSCH on the serving cell. For example, the PDCCH of a secondary cell (SCell) can schedule communications on a primary cell (PCell) or a primary secondary cell (PSCell). As another example, the PDCCH of a serving cell (e.g., PCell, PSCell, or SCell) can use a single DCI to schedule PDSCH on multiple cells. However, scheduling multiple cells using a single DCI may increase the size of the DCI and increase the blind decoding complexity of the PDCCH, which negates some of the benefits of DSS, and it uses significant computational and communication resources of the UE.

[0065] Some of the techniques and apparatus described herein provide for single DCI operation, scheduling, and configuration of multiple bandwidth parts (BWPs) associated with multiple CCs, such as for DSS deployment. For example, some of the techniques and apparatus described herein enable a virtual BWP (defined below) associated with a first BWP and a second BWP. The DCI for the virtual BWP can indicate the configuration for the first BWP and / or the second BWP. In some aspects, the virtual BWP can be configured such that the DCI size for the virtual BWP is smaller than the total DCI size of the two DCIs that would be used to configure the first BWP and the second BWP, respectively, thereby reducing DCI size and PDCCH overhead. Some of the techniques and apparatus described herein enable a single DCI to be processed similarly to multiple DCIs corresponding to the first BWP and the second BWP. In such cases, in some cases, DCI size reduction can be achieved through DCI field size compression to achieve DCI size alignment between single-CC scheduling and multi-CC scheduling. In this way, computational and communication resource usage is reduced, and the efficiency of DSS-based communications is improved.

[0066] Figure 3 is a diagram illustrating an example 300 of configuration, scheduling, and communication over multiple BWPs using a single DCI according to the present disclosure. As shown, example 300 includes UE 120 and BS 110.

[0067] As shown in reference numeral 310, BS 110 may provide configuration information to UE 120. The configuration information may be provided via, for example, radio resource control (RRC) information, medium access control (MAC) signaling, downlink control information (DCI), a combination thereof, or the like. The configuration information may configure a first CC (CC1) and a second CC (CC2). A CC is a frequency block used in association with carrier aggregation (CA). Multiple CCs may be assigned to the same user, thereby increasing the data rate achievable by the user. A user's CCs may be intra-band (e.g., all in the same frequency band) or inter-band (e.g., in different frequency bands) and may be contiguous or non-contiguous in frequency.

[0068] In some aspects, the configuration information may configure a virtual CC. A virtual CC is a CC configured such that a single DCI associated with the virtual CC can indicate scheduling information, BWP configuration information, and / or BWP switching information for both CC1 and CC2. In some aspects, the virtual CC may be referred to herein as CC3. In some aspects, the configuration information may not configure a virtual CC. For example, the configuration information may only configure CC1 and CC2. In some aspects, CC1 may be the first serving cell of UE 120, and CC2 may be the second serving cell of UE 120. In other aspects, CC1 and CC2 may be the same serving cell of UE 120. For example, CC1 and / or CC2 may be a PCell, SCell, PSCell, etc. CC1 and CC2 may have the same bandwidth or different bandwidths. In some aspects, the BWPs activated for CC1 and CC2 may have the same bandwidth or different bandwidths.

[0069] As shown, configuration information can configure the BWP for a CC (e.g., CC1, CC2, and / or virtual CC). For example, configuration information can configure a first BWP to be used for a first CC, a second BWP to be used for a second CC, and a virtual BWP to be used for a virtual BWP. A BWP is a contiguous set of physical resource blocks (PRBs) on a given carrier. These PRBs can be selected from a contiguous subset of common resource blocks for a given numerology. For a given numerology, a BWP is defined by a set of parameters including subcarrier spacing (SCS), symbol duration, and cyclic prefix length. A virtual BWP is a BWP configured for a virtual CC. One or more parameters of a virtual BWP (e.g., bandwidth, resource block granularity (RBG), resource allocation type, numerology, etc.) can be used for both the first BWP and the second BWP, as described elsewhere herein. As further shown, configuration information can indicate a BWP configuration for a BWP. For example, a BWP configuration can identify one or more parameters of a corresponding BWP, a corresponding BWP index for the corresponding BWP, and so on.

[0070] In some aspects, a virtual BWP may include the bandwidths of BWP1 and BWP2. For example, the respective configured bandwidths of BWP1 and BWP2 may be within the configured bandwidth of the virtual BWP. In other aspects, at least a portion of the bandwidth of one or more of BWP1 or BWP2 may be outside the bandwidth of the virtual BWP.

[0071] In some aspects, parameter configurations can be shared between a virtual BWP and BWP1 or BWP2. For example, a virtual CC can be associated with one or more BWP configurations for CC1 and / or CC2. One or more parameters (e.g., digital scheme, bandwidth, RBG, etc.) can be shared between the BWP configuration for the virtual BWP and the BWP configuration for CC1 and / or CC2. For example, the digital scheme and / or parameters can be identical between the BWP for CC1 and the BWP corresponding to CC1 included in the virtual BWP. Similarly, the digital scheme and / or basic parameters can be identical between the BWP for CC2 and the BWP corresponding to CC2 included in the virtual BWP. Parameters shared between the BWP for CC1 and the BWP corresponding to CC1 included in the virtual BWP can be referred to as having the same values for the corresponding regions of the BWP for CC1 and the virtual BWP (wherein the virtual BWP region is the BWP corresponding to CC1 included in the virtual BWP). Parameters shared between CC2's BWP and the BWP corresponding to CC2 included in the virtual BWP can be said to have the same values for the corresponding regions of CC2's BWP and the virtual BWP (where the virtual BWP region is the BWP corresponding to CC1 included in the virtual BWP). Therefore, a single DCI message indicating the configuration of a virtual CC can indicate parameters for CC1 and CC2.

[0072] As a specific example, CC1 may be associated with resource allocation (RA) type 0, an RBG of 8 resource blocks (RBs), and a bandwidth (BW) of 100 RBs. This may correspond to a frequency domain resource allocation (FDRA) field size of 13 bits for the DCI for CC1. CC2 may be associated with RA type 0, an RBG of 16 RBs, and a BW of 273 RBs, resulting in an FDRA field size of 18 bits for the DCI for CC2. Therefore, signaling the configuration of the BWP for CC1 and CC2 separately may use a total of 18+13=31 bits. However, if CC1 is configured with RA type 0, an RBG of 16 RBs (compared to 8 RBs described above), and a BW of 100 RBs in a virtual CC, the DCI FDRA field for CC1 may use 7 bits. Similarly, if CC2 is configured with RA type 0, an RBG of 16 RBs, and a BW of 273 RBs in a virtual CC, the DCI FDRA field for CC2 may use 18 bits. Therefore, the FDRA field size for the DCI for the virtual CC is 7 + 18 = 25 bits. This represents a 6-bit reduction compared to providing separate DCI for each CC by using the same FDRA field for both CCs and inputting the virtual CC's BWP configuration into CC1. Consequently, the size of the DCI is smaller than the cumulative size of the DCI used to indicate one or more parameters for the BWP for CC1 and CC2. In contrast, by providing separate DCI for CC1, an 8-RB RBG can be used, providing increased flexibility with adjustable DCI size and BWP configuration.

[0073] In some aspects, the configuration information may indicate the corresponding BWP configuration for CC1 and CC2. For example, the configuration information may not identify a virtual BWP configuration for a virtual CC. In this case, the corresponding BWP configuration may include a single carrier scheduling configuration. For example, the physical downlink shared channel (PDSCH) configuration parameters for CC1 and CC2 may be used for the BWP configuration. In this case, DCI field size compression may be used to achieve DCI size alignment between single-CC scheduling and multi-CC scheduling (e.g., so that the multi-CC DCI has the same size as the single-CC DCI for CC1 or CC2, thereby reducing DCI size and blind decoding complexity) without requiring additional RRC signaling. As a specific example, CC1 may be associated with RA type 0, RBGs of 8 RBs, and a BW of 100 RBs. This may correspond to a FDRA field size of 13 bits for DCI for CC1. CC2 may be associated with RA type 0, RBGs of 16 RBs, and a BW of 273 RBs, resulting in an FDRA field size of 18 bits for DCI for CC2. Therefore, signaling the configuration of the BWP for CC1 and CC2 separately can use a total of 18+13=31 bits. However, in some aspects, the interpretation of the DCI fields for CC1 and / or CC2 can be modified so that the DCI scheduling both CC1 and CC2 can be less than 31 bits. For example, the FDRA field in the DCI can be defined as 13 or 18 bits. The field with 13 or 18 bits can then be split into two subfields: one subfield for CC1 and another subfield for CC2. In this example, each subfield has less than 13 or 18 bits. The UE 120 can interpret the subfields for CC1 and CC2 as if the subfields are one or more most significant bits (MSB) or least significant bits (LSB) of the FDRA field for CC1 and CC2, respectively. For example, consider when the subfield for CC1 has 6 bits and the subfield for CC2 has 12 bits (a total of 18 bits). Then, 6 bits can be considered as the MSB or LSB bits of the FDRA field for CC1, and 12 bits can be considered as the MSB or LSB bits of the FDRA field for CC2. The remaining 7 bits of the FDRA field for CC1 and 6 bits of the FDRA field for CC2 can be considered as zero or another padding value. The split ratio of the FDRA field for CC1 and CC2 into subfields can be configured by higher layers, or can be based at least in part on the ratio of bandwidths, the number of RBs, etc.

[0074] In some aspects, the configuration information may identify multiple BWPs for a CC. In this case, as shown at 320, BS 110 may provide DCI to activate or switch one or more BWPs. For example, the DCI may indicate the BWP to be activated or deactivated for the corresponding CC, or may indicate the BWP to be switched to by the CC (e.g., using a BWP index associated with the BWP). The DCI may be provided in a PDCCH, etc.

[0075] In some aspects, a DCI message activating or switching one or more BWPs may involve a virtual CC / virtual BWP configuration (e.g., may indicate a BWP configuration for a virtual BWP). In this case, configuration information may identify one or more associations (e.g., one or more mappings) between a BWP index field value of the DCI for the virtual CC and the BWP index of the BWP to be activated, deactivated, or switched for CC1 and / or CC2. For example, the association between the BWP index field value and the BWP indexes of CC1 and CC2 may be configured via RRC signaling. The BWP index field of the DCI may indicate the BWP index for the virtual CC, and the UE 120 may identify the BWP for CC1 and CC2 based at least in part on the association indicated by the configuration information. Thus, a virtual BWP may be associated with multiple BWP configurations indicating corresponding parameters for CC1 and CC2. Furthermore, a single BWP index field of the DCI may jointly indicate the corresponding BWP indices of multiple BWPs.

[0076] In some aspects, the BWP index for CC1 may be switched by the DCI for CC1, and / or the BWP index for CC2 may be switched by the DCI for CC2. Additionally or alternatively, the BWP index for CC1 may be switched by the DCI for a virtual CC, and / or the BWP index for CC2 may be switched by the DCI for the virtual CC. In this case, the target BWP for a CC may be associated with different parameter values when the DCI for the virtual CC is used to switch CCs compared to when the DCI for the CC is used to switch CCs. In other words, the parameters associated with the target BWP may be different when determined at least in part based on the BWP configuration for the target BWP than when determined at least in part based on the BWP configuration for the virtual BWP (associated with the virtual CC). For example, UE 120 may read each field of the DCI based on the BWP configuration for the target BWP. Therefore, if the target BWP is indicated by DCI for a virtual CC, UE 120 can process the DCI according to the BWP configuration for the virtual BWP, and if the target BWP is indicated by DCI for a CC, UE 120 can process the DCI according to the BWP configuration for the CC. Therefore, different values of parameters (e.g., RBG1, etc.) can be indicated by selectively indicating BWP activation / deactivation / switching using DCI associated with a CC or a virtual CC.

[0077] In some aspects, the BWP index for CC1 and / or CC2 can be switched by a single DCI message associated with CC1 and CC2. For example, UE 120 can be configured (e.g., using RRC signaling, etc.) with information indicating an association (e.g., mapping) between the BWP index of a single DCI message and the BWP index of the BWP associated with CC1 or CC2. In some aspects, the DCI can include a single BWP indicator field that jointly indicates the BWP index for CC1 and CC2. In some aspects, the DCI can include two BWP indicator fields that independently (e.g., separately) indicate the BWP index for CC1 and CC2. For example, the first bandwidth part and the second bandwidth part can be associated with respective bandwidth part index fields that indicate the respective bandwidths of the first bandwidth part and the second bandwidth part, respectively.

[0078] In some aspects, UE 120 may switch CC1 based at least in part on receiving a DCI indicating a switch to CC2, or vice versa. For example, CC1 and CC2 may be configured to use the same search space set identifier (SSSI). UE 120 may be associated with a rule indicating that after performing a BWP switch, the SSI for CC1 (e.g., the scheduling CC) and the SSI for CC2 (e.g., the scheduled CC) will be the same. Thus, when UE 120 performs a BWP switch for either the scheduling CC or the scheduled CC, UE 120 may also switch the BWP for the other CC (e.g., the scheduled CC and the scheduling CC, respectively) such that, after performing the switch, CC1 and CC2 are associated with the same SSI. Therefore, to satisfy the above rule, if the BWP for CC1 is switched, then the BWP for CC2 should be switched, and vice versa.

[0079] As shown at 330, UE 120 may receive DCI scheduling communications on BWP1 (e.g., the active BWP for CC1) and BWP2 (e.g., the active BWP for CC2). In some aspects, the DCI may be associated with a virtual CC (e.g., a virtual BWP). In some aspects, the DCI may be associated with one of CC1 or CC2. In some aspects, the DCI may be associated with both CC1 and CC2. As shown at 340, UE 120 may determine parameters for BWP1 and BWP2 based at least in part on the DCI and based on the BWP configuration for the virtual BWP (e.g., associated with the virtual CC) or the BWP configurations for BWP1 and BWP2. For example, UE 120 may determine the parameters based on the BWP configuration corresponding to the CC / BWP associated with the DCI. If the DCI is associated only with CC1 (e.g., BWP1), UE 120 may determine the parameters based on the BWP configuration of CC1 / BWP1. If the DCI is associated with a virtual CC (e.g., a virtual BWP), UE 120 may determine the parameters based on the BWP configuration of the virtual CC / BWP. If the DCI is associated with CC1 and CC2 (e.g., BWP1 and BWP2), UE 120 may determine the parameters based on the separate BWP configurations of CC1 and CC2. The DCI may be provided on a PDCCH, etc.

[0080] As shown at 350, UE 120 and BS 110 may perform scheduled communications on BWP1 and BWP2. For example, UE 120 may transmit one or more PUSCHs or receive one or more PDSCHs based on the DCI. UE 120 may interpret the DCI as described above in conjunction with 330 and 340. Thus, compared to transmitting two separate DCIs for CC1 and CC2, the size and decoding complexity of the DCI may be reduced, which conserves computational and communication resources of UE 120.

[0081] As pointed out above, Figure 3 is provided as an example. Other examples may differ from those described in relation to Figure 3 Examples described.

[0082] Figure 4 4 is a diagram illustrating an example 400 of BWP operation based on a virtual BWP (shown by reference numeral 405) and BWP operation based on multiple CCs (shown by reference numeral 410). As shown by reference numeral 415, a virtual CC (e.g., CC3) can be configured and associated with a virtual BWP. In this example, the bandwidths of CC1 and CC2 are included within the virtual CC. As shown by reference numeral 420, a single DCI can schedule CC3. For example, a single DCI can schedule communications on CC1 and CC2, similar to scheduling two communications on CC3, with the two communications occurring within the respective bandwidths of CC1 and CC2. UE 120 can determine parameters for communication based at least in part on the BWP configuration for CC3.

[0083] As shown by reference numeral 425, in multi-CC based BWP operation, a single DCI can schedule communications on both CC1 and CC2. For example, a single DCI for scheduling CC1 and CC2 can be interpreted similarly to two DCIs scheduling CC1 and CC2, respectively. Therefore, the UE behavior can be similar to cross-carrier scheduling from one CC to two CCs.

[0084] As pointed out above, Figure 4 is provided as one or more examples. Other examples may differ from those regarding Figure 4 Examples described.

[0085] Figure 5is a diagram illustrating an example 500 of configurations for a virtual CC, a first CC, and a second CC according to the present disclosure. As shown, example 500 includes CC1 (e.g., a first serving cell) and CC2 (e.g., a second serving cell). As described above, in some aspects, CC1 and CC2 may be different serving cells, while in other aspects, CC2 and CC1 may be the same serving cell. As indicated by reference numeral 510, CC1 is associated with a first BWP configuration, and as indicated by reference numeral 520, CC2 is associated with a second BWP configuration. If a UE receives DCI for CC1, as indicated by reference numeral 530, the UE may interpret the DCI for CC1 based on the BWP configuration for CC1. Similarly, if the UE receives DCI for CC2, as indicated by reference numeral 540, the UE may interpret the DCI for CC2 based on the BWP configuration for CC2.

[0086] As indicated by reference numeral 550, a virtual CC can be associated with a BWP configuration. As shown, the rectangle indicating the BWP configuration for the virtual CC contains parameters x and y of the BWP configuration for CC1 and CC2. This may indicate that parameters x and y are shared between the virtual BWP configuration and the BWP configuration for CC1 and CC2. In other words, for the virtual BWP configuration, parameters x and y can be borrowed from the BWP configuration for CC1 and CC2. Parameters 1 and 2 can be configured separately for the virtual BWP configuration and for the BWP configuration for CC1 and CC2. Therefore, compared to using only CC-specific BWP configurations, the virtual BWP configuration provides flexibility in parameter configuration and DCI size. If a UE receives DCI for a virtual CC, as indicated by reference numeral 560, the UE may interpret the DCI for the virtual CC based on the BWP configuration for the virtual CC. For example, the UE may determine parameters 1 and 2 for CC1 and CC2 based on the virtual BWP configuration, and may also determine parameters x and y based on the virtual BWP configuration (where x and y are shared with the BWP configuration for CC1 and CC2).

[0087] As pointed out above, Figure 5 is provided as one or more examples. Other examples may differ from those regarding Figure 5 Examples described.

[0088] Figure 6This diagram illustrates example 600 of BWP switching based at least in part on a BWP search space, according to the present disclosure. As shown in example 600, CC1 and CC2 may be associated with BWP configurations 1 and 2, respectively. BWP configuration 1 is associated with search space 1, and BWP configuration 2 is associated with search space 2. A search space is an area in a downlink resource grid that may carry a PDCCH. A UE searches the search space for a PDCCH associated with the UE. The PDCCH may carry DCI, and the UE may implement parameters indicated by the DCI.

[0089] As shown by reference numeral 610, if the DCI for CC1 indicates that CC1 will switch from BWP configuration 1 to BWP configuration 2, CC2 may also switch from BWP configuration 1 to BWP configuration 2 (as shown by reference numeral 620), so that the same search space or search space set is used for both CCs / BWPs. Similarly, a virtual CC including CC1 and CC2 may be configured with BWP configuration 1 and BWP configuration 2 associated with respective search spaces 1 and 2.
