[0003] Public domain

[0004] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for bandwidth portion indication for multiple cells scheduled by a single downlink control information message.

[0005] Related technical description

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless communication network may include several base stations (BS) that can support communication of 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, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies.

[0189] Detailed Description

[0190] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it 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 will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0191] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can 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.

[0192] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0193] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (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.

[0194] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0195] 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 (such as direct physical connections, virtual networks, etc.) using any suitable transport network.

[0196] 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 the 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.

[0197] 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).

[0198] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0199] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may 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, 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 component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0200] Some UEs may be considered as machine type communication (MTC) UEs, 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 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 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 client equipment (CPE). UE120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, electrically coupled, and the like.

[0201] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may 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 may be deployed.

[0202] 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.

[0203] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0204] Figure 2A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 One for each base station and one for each UE in the base station 110. 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.

[0205] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for 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), 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 respective 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.

[0206] 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.

[0207] 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 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0208] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the base station 110 may perform one or more techniques associated with bandwidth portion indication for multiple cells scheduled by a single downlink control information (DCI) message, 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(s) may perform or direct e.g. Fig.12 The process 1200 Fig.13 1300, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, interpretation, etc.) by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Fig.12 The process 1200 Fig.13 The process 1300 of , and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, interpreting instructions, etc. The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0209] In some aspects, UE 120 may include: means for receiving a single DCI message scheduling communications on multiple cells, wherein the single DCI message indicates multiple bandwidth portions corresponding to the multiple cells on which communications are scheduled; and means for communicating using the multiple bandwidth portions corresponding to the multiple cells, wherein the means for communicating includes: means for transmitting communications in the multiple bandwidth portions corresponding to the multiple cells, and / or means for receiving communications in the multiple bandwidth portions corresponding to the multiple cells, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0210] In some aspects, base station 110 may include: means for transmitting a single DCI message that schedules communications on multiple cells, wherein the single DCI message indicates multiple bandwidth portions corresponding to the multiple cells on which communications are scheduled; and means for communicating using the multiple bandwidth portions corresponding to the multiple cells, wherein the means for communicating include: means for transmitting communications in the multiple bandwidth portions corresponding to the multiple cells, and / or means for receiving communications in the multiple bandwidth portions corresponding to the multiple cells, etc. In some aspects, such means may include means for combining 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.

[0211] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0212] Figure 3-6 is a diagram illustrating example bandwidth portions in accordance with various aspects of the present disclosure.

[0213] New Radio (NR) supports the use of multiple different parameter designs (e.g., 15 kHz, 30 kHz, 60 kHz, 120 kHz, etc. subcarrier spacing options) and multiple different slot durations (e.g., 0.5 ms, 0.25 ms, 0.125 ms, etc.). In addition, the wideband bandwidth (e.g., system bandwidth, etc.) in NR can be up to 100 MHz (e.g., for sub-6 GHz bands), up to 400 MHz (e.g., for bands above 6 GHz), etc. In some cases, there may be scenarios where the UE only monitors a subset of the wideband bandwidth or only uses a subset of the wideband bandwidth for service. The subset may be referred to as a bandwidth portion and may be limited for reduced power consumption, for flexible bandwidth allocation, due to UE capabilities, due to the UE being in a power saving mode, etc.

[0214] For example, Figure 3As shown in , the total carrier 310 may span a wideband bandwidth, and the bandwidth portion (BWP) 320 may span a portion of the total carrier 310. For example, the BWP 320 may have a smaller or narrower bandwidth than the total carrier 310 due to UE capabilities (such as reduced UE bandwidth capabilities). As a more specific example, the UE may be a NB-IoT UE with limited bandwidth capabilities. Additionally or alternatively, the BWP 320 may have a smaller bandwidth than the total carrier 310 to achieve reduced power consumption, to achieve flexible bandwidth allocation (e.g., on a specific cell or carrier or across cells or carriers), etc. .

[0215] As another example, and if Figure 4 As shown in , the total carrier 410 can span a wideband bandwidth, the first bandwidth portion (shown as BWP1) 420 can span a portion of the total carrier 410, and the second bandwidth portion (BWP2) 430 can span a portion of the first bandwidth portion. In this case, the first bandwidth portion 420 can represent the UE bandwidth capability, and the second bandwidth portion 430 can represent the bandwidth to be monitored by the UE or served by the UE. For example, the UE may be capable of communicating on the entire first bandwidth portion 420, but may be configured to communicate only in the second bandwidth portion 430 (e.g., for a period of time) to save battery power. In this case, the UE may be capable of switching between a full bandwidth configuration (where the UE monitors the first bandwidth portion 420 or is served on the first bandwidth portion 420) and a bandwidth portion configuration (where the UE monitors the second bandwidth portion 430 or is served on the second bandwidth portion 430). For example, when the UE is scheduled to transmit or receive data (e.g., a threshold amount of data), the UE may transition to a full bandwidth configuration, and when the UE is not scheduled to transmit or receive data, the UE may transition to a bandwidth partial configuration to save battery power.

[0216] As another example, and if Figure 5 As shown in , the total carrier 510 can span a wideband bandwidth, which can be divided into multiple bandwidth portions, such as a first bandwidth portion (BWP1) 520 and a second bandwidth portion (BWP2) 530. The bandwidth portions 520, 530 can each span a portion of the total carrier 510. In some aspects, different bandwidth portions can be associated with different parameter designs (such as 15kHz, 30kHz, 60kHz, 120kHz, etc.). Additionally or alternatively, guard bands 540 (e.g., gaps) can be configured between different bandwidth portions to reduce interference between bandwidth portions and / or parameter designs.

[0217] As another example, and if Figure 6As shown in , the total carrier 610 can span a wideband bandwidth that can be divided into multiple bandwidth parts, such as a first bandwidth part (BWP1) 620 and a second bandwidth part (BWP2) 630. In addition, the total carrier 610 may include a third bandwidth part 640 that is not used by the UE. For example, the first bandwidth part 620 and the second bandwidth part 630 may be associated with the same network operator and / or may be used to support intra-band carrier aggregation, while the third bandwidth part 640 may be associated with different network operators and / or may not be used to support carrier aggregation. In some implementations, a synchronization signal (SS) block (e.g., including one or more of a PSS, SSS, a physical broadcast channel (PBCH), etc.) may be transmitted on one bandwidth part and may include information about multiple bandwidth parts to save network resources.

[0218] As indicated above, Figure 3-6 are provided as examples. Other examples may differ from those in combination with Figure 3-6 Examples described.

[0219] Figure 7 7 is a diagram illustrating an example 700 of scheduling downlink control information (DCI) (eg, a single DCI message) for multiple cells in accordance with various aspects of the present disclosure. Figure 7 As shown in , base station 110 and UE 120 may communicate with each other.

[0220] As shown, the base station 110 may transmit to the UE 120 DCI 705 (e.g., a single DCI message) that schedules multiple communications for the UE 120. The multiple communications may be scheduled for at least two different cells. In some cases, a cell may be referred to as a carrier or component carrier (CC). In some cases, a DCI that schedules communications for a cell via which the DCI is transmitted may be referred to as a self-carrier (or self-cell) that schedules the DCI. In some cases, a DCI that schedules communications for a cell via which the DCI is transmitted may be referred to as a cross-carrier (or cross-cell) that schedules the DCI. In some aspects, the DCI 705 may be a cross-carrier scheduled DCI, and may or may not be a self-carrier scheduled DCI. In some aspects, the DCI 705 that schedules communications in at least two cells may be referred to as a combined DCI, a single DCI message that schedules communications on multiple cells, and the like.

[0221] In example 700, DCI 705 schedules communications for a first cell 710 (shown as CC0) that carries DCI 705, schedules communications for a second cell 715 (shown as CC1) that does not carry DCI 705, and schedules communications for a third cell 720 (shown as CC2) that does not carry DCI 705. In some aspects, DCI 705 may schedule communications with Figure 7 , (eg, two cells, four cells, five cells, etc.). The number of cells may be greater than or equal to two.

[0222] The communication scheduled by the DCI 705 may include data communication, such as physical downlink shared channel (PDSCH) communication, physical uplink shared channel (PUSCH) communication, etc. For data communication, the DCI 705 may schedule a single transport block (TB) across multiple cells, or may schedule multiple TBs separately in multiple cells. Additionally or alternatively, the communication scheduled by the DCI 705 may include reference signals, such as channel state information reference signals (CSI-RS), sounding reference signals (SRS), etc. For reference signals, the DCI 705 may trigger a single resource for reference signal transmission across multiple cells, or may schedule multiple resources separately for reference signal transmission in multiple cells. In some cases, the scheduling information in the DCI 705 may be indicated once and reused for multiple communications (e.g., on different cells), such as a modulation and coding scheme (MCS), resources to be used for acknowledgment (ACK) or negative acknowledgment (NACK) of communications scheduled by the DCI 705, resource allocation for scheduled communications, etc., to save signaling overhead.

[0223] In some aspects, base station 110 may configure a cell using multiple bandwidth parts (BWPs), such as those described above. Figure 3-6 As described. In this scenario, when base station 110 transmits DCI to UE 120 to schedule communication (e.g., uplink communication or downlink communication), base station 110 may include in the DCI (e.g., in a BWP indicator field of the DCI) an indication of the BWP on which the communication is scheduled. Subsequently, UE 120 may transmit or receive (e.g., monitor) communications in the indicated BWP on the cell. For example, if the BWP indicator field in the DCI indicates a BWP that is not the currently active BWP for the cell (e.g., the BWP is being used by UE 120 to communicate on the cell), UE 120 may switch to the indicated BWP, which then becomes the active BWP, to transmit or receive scheduled communications.

[0224] However, when a single DCI message schedules communications on multiple cells, such as Figure 7 As shown in , each cell may have a different set of configured BWPs. In this case, UE 120 may misinterpret the BWP indication included in a single DCI message and may select a BWP that is not intended by base station 110. This may result in errors and interrupted communications, may increase latency, may reduce reliability, may reduce spectral efficiency (e.g., due to retransmissions), etc.

[0225] Some techniques and apparatus described herein enable a UE 120 to correctly interpret a BWP indication included in a single DCI message scheduling communications in multiple cells, and apply the BWP indication to determine a corresponding BWP on each of the multiple cells. In this way, communication errors may be reduced, latency may be reduced, reliability may be increased, spectral efficiency may be improved, etc. In addition, some techniques and apparatus described herein enable a single BWP indication to be applied across multiple cells, thereby reducing signaling overhead.

[0226] As indicated above, Figure 7 are provided as examples. Other examples may differ from those described herein. Figure 7 Examples described.

[0227] Figure 8 8 is a diagram illustrating an example 800 of BWP indication for multiple cells scheduled by a single DCI message in accordance with various aspects of the present disclosure. Figure 8 As shown in , base station 110 and UE 120 may communicate with each other.

[0228] As indicated by reference numeral 805, the base station 110 may transmit BWP configurations for multiple cells to the UE 120. For example, the base station 110 may configure one or more BWPs for each cell configured for the UE 120. The BWP may be identified using a BWP identifier (shown as a BWP ID). Similarly, a cell may be identified using a cell identifier (shown as a cell ID). In example 800, the base station 110 configures a first BWP with a BWP ID of 1 and a second BWP with a BWP ID of 2 for a first cell with a cell ID of 0. The base station 110 also configures a third BWP with a BWP ID of 3 and a fourth BWP with a BWP ID of 4 for a second cell with a cell ID of 1. In some aspects, the base station 110 may configure, for each cell configured for the UE 120, one or more uplink BWPs for uplink communications on the cell, and / or one or more downlink BWPs for downlink communications on the cell. In some aspects, the BWP configuration may be included in a configuration message, such as a radio resource control (RRC) message (eg, an RRC configuration message, an RRC reconfiguration message, etc.).

[0229] As indicated by reference numeral 810, base station 110 may transmit a single DCI message to UE 120 that schedules communications over multiple cells, as described above in conjunction with Figure 7 As shown by reference numeral 815, a single DCI message may indicate multiple BWPs corresponding to the multiple cells on which communications are scheduled. In example 800, the single DCI message indicates that a first communication is scheduled on a first BWP (having a BWP ID of 1) in a first cell (cell 0), and a second communication is scheduled on a third BWP (having a BWP ID of 3) in a second cell (cell 1). Figure 9-11 Additional details are described regarding techniques for indicating multiple BWPs.

[0230] As indicated by reference numeral 820, UE 120 and base station 110 may communicate with each other using multiple BWPs corresponding to multiple cells (indicated in a single DCI message). For example, base station 110 may transmit downlink communications to UE 120 using multiple BWPs corresponding to multiple cells, and UE 120 may monitor and / or receive downlink communications using multiple BWPs corresponding to the multiple cells. Alternatively, UE 120 may transmit uplink communications to base station 110 using multiple BWPs corresponding to multiple cells, and base station 110 may monitor and / or receive uplink communications using multiple BWPs corresponding to the multiple cells.

[0231] For example, if a single DCI message includes downlink grants that schedule downlink communications on multiple cells, the single DCI message may indicate multiple downlink BWPs corresponding to the multiple cells. In some aspects, the base station 110 may configure multiple downlink BWPs for each cell configured for the UE 120, as described above. In this case, the single DCI message may indicate the downlink BWP for each cell on which the downlink communications are scheduled by the single DCI message. The base station 110 may transmit downlink communications on the indicated downlink BWP for the respective cell, and the UE 120 may monitor and / or receive downlink communications on the indicated downlink BWP for the respective cell.

[0232] As another example, if a single DCI message includes an uplink grant that schedules uplink communications on multiple cells, the single DCI message may indicate multiple uplink BWPs corresponding to the multiple cells. In some aspects, the base station 110 may configure multiple uplink BWPs for each cell configured for the UE 120, as described above. In this case, the single DCI message may indicate an uplink BWP for each cell on which uplink communications are scheduled by the single DCI message. The UE 120 may transmit uplink communications on the indicated uplink BWP for the respective cell, and the base station 110 may monitor and / or receive uplink communications on the indicated uplink BWP for the respective cell.

[0233] By implementing the indication of multiple BWPs corresponding to multiple cellular cells in a single DCI message, communication errors can be reduced, waiting time can be reduced, reliability can be improved, spectrum efficiency can be improved, etc. In addition, according to some techniques described in this article, signaling overhead can be reduced. Figure 9-11 Additional details are described regarding techniques for indicating multiple BWPs. In some aspects, a first technique described below may be used to indicate multiple BWPs for downlink communications, and a second (e.g., different) technique described below may be used to indicate multiple BWPs for uplink communications. In some aspects, the same technique may be used to indicate multiple BWPs for both downlink and uplink communications.

[0234] As indicated above, Figure 8 are provided as examples. Other examples may differ from those described herein. Figure 8 Examples described.

[0235] Fig. 9 is a diagram illustrating an example 900 of BWP indication for multiple cells scheduled by a single DCI message in accordance with various aspects of the present disclosure.

[0236] As indicated by reference numeral 905, in some aspects, a single DCI message includes a single BWP indicator value within a single BWP indicator field. A "BWP indicator value" may refer to a value that indicates or identifies one or more BWPs on which one or more communications are scheduled. A "BWP indicator field" may refer to a field in a single DCI message that includes a BWP indicator value, such as a dedicated field in a single DCI message that includes a BWP indicator value. Fig. 9 An example single DCI message includes a single field of bits dedicated to carrying a BWP indicator value. By using a single BWP indicator field and a single BWP indicator value, signaling overhead may be reduced and network resources may be saved.

[0237] In example 900, a single BWP indicator value represents a single value for identifying multiple BWPs for the multiple cells. For example, a single BWP indicator value (shown as 0) may represent a single value (e.g., also 0) identifying the corresponding BWP on which a single DCI message for each cell schedules communications. As shown by reference numeral 910, a single value of 0 indicates a first BWP (with a BWP ID of 1) on a first cell (cell 0) and indicates a second BWP (with a BWP ID of 3) on a second cell (cell 1). In some aspects, the same BWP ID may be used in different cells, but may represent different BWPs in those cells. Thus, the BWP IDs corresponding to the BWP indicator values ​​(and the single value) may be the same in different cells, or may be different in different cells.

[0238] The example BWP indicator value of 0 in example 900 may indicate an initial BWP in an ordered set of BWPs for a first cell (e.g., a first BWP in an ordered set), and may also indicate an initial BWP in an ordered set of BWPs for a second cell (e.g., a first BWP in an ordered set). For example, if the ordered set of BWPs for the first cell includes a BWP with an ID of 1 and a BWP with an ID of 2, the BWP indicator value of 0 may indicate the BWP with an ID of 1 (e.g., assuming that the ordered set of BWPs is ordered from the smallest or lowest BWP ID to the largest or highest BWP ID). Similarly, if the ordered set of BWPs for the second cell includes a BWP with an ID of 3 and a BWP with an ID of 4, the BWP indicator value of 0 may indicate the BWP with an ID of 3. In some aspects, the base station 110 may transmit a configuration (e.g., in an RRC message) to the UE 120 indicating the ordered set of BWPs for each cell (e.g., the order of the ordered set). In some aspects, the ordered set of BWPs for each cell (eg, the order of the ordered set) may be specified according to a wireless communication standard.

[0239] In some aspects, UE 120 may have different numbers of BWPs configured in different cells. This may lead to misinterpretation of the BWP indicator value. To alleviate this problem, UE 120 may follow a rule to determine the number of bits (e.g., bit length, bit width, or bit size) included in the BWP indicator field (e.g., the number of bits of the BWP indicator field). The rule may be configured by base station 110 or may be specified according to a wireless communication standard.

[0240] For example, as indicated by reference numeral 915, the base station 110 may transmit a configuration (e.g., in an RRC message) to the UE 120 indicating the number of bits to be included in a single BWP indicator field (e.g., the bit length or bit size of the field). For example, the base station 110 may indicate that the length of the BWP indicator field is 1 bit or the length is 2 bits, etc. Alternatively, the base station 110 may indicate a manner of determining the bit length or number of bits. In some aspects, the number of bits (e.g., the bit length or bit size) or the manner of determining the number of bits may be specified in a wireless communication standard.

[0241] In some aspects, the number of bits in the BWP indicator field comprising a single DCI message may be based at least in part on the number of BWPs configured for a cell (e.g., for any cell) on which communications are scheduled by a single DCI message. In some aspects, all cells scheduled by a single DCI message may need to be configured with the same number of BWPs (e.g., the same number of UE-specific RRC-configured downlink BWPs for a single DCI that schedules downlink communications, or the same number of UE-specific RRC-configured uplink BWPs for a single DCI that schedules uplink communications). For example, if all of the multiple cells scheduled by a single DCI message have two configured BWPs, the BWP indicator field may include one bit. As another example, if all of the multiple cells scheduled by a single DCI message have three configured BWPs, or if all of the multiple cells scheduled by a single DCI message have four configured BWPs, the BWP indicator field may include two bits. This reduces the possibility of ambiguity when scheduling communications on multiple cells.

[0242] In some aspects, the number of bits in the BWP indicator field comprising a single DCI message may be based at least in part on the maximum number of BWPs permitted to be configured for a cell. For example, if a maximum of four BWPs are permitted to be configured per cell (e.g., if a cell is not permitted to be configured with more than four BWPs), the BWP indicator field may include two bits.

[0243] In some aspects, the number of bits in the BWP indicator field included in a single DCI message may be based at least in part on a minimum number of BWPs configured for a cell in a plurality of cells scheduled by the single DCI message compared to all other cells in the plurality of cells. For example, if a first cell scheduled by a single DCI message has three configured BWPs and a second cell scheduled by the single DCI message has two configured BWPs, the BWP indicator field may include one bit (e.g., to indicate two possible values ​​for each of the two configured BWPs for the second cell). This may reduce signaling overhead.

[0244] In some aspects, the number of bits in the BWP indicator field included in a single DCI message may be based at least in part on a maximum number of BWPs configured for a cell in a plurality of cells scheduled by the single DCI message compared to all other cells in the plurality of cells. For example, if a first cell scheduled by a single DCI message has three configured BWPs and a second cell scheduled by the single DCI message has two configured BWPs, the BWP indicator field may include two bits (e.g., to enable indication of each of the three configured BWPs for the first cell). This may increase scheduling flexibility.

[0245] In some aspects, the number of bits in the BWP indicator field comprising a single DCI message may be based at least in part on the number of BWPs configured for a particular cell. The particular cell may or may not be included in a plurality of cells scheduled by a single DCI message. In some aspects, the particular cell may be a cell (e.g., a scheduling cell) via which the single DCI message is received. In some aspects, the particular cell may be a cell with a minimum cell identifier or a minimum subcarrier spacing (SCS) among all cells in the plurality of cells scheduled by a single DCI message (or a cell set including the plurality of cells and including the scheduling cell). In some aspects, the particular cell may be a cell with a maximum cell identifier or a maximum SCS among all cells in the plurality of cells scheduled by a single DCI message (or a cell set including the plurality of cells and including the scheduling cell).

[0246] In some aspects, a single BWP indicator value included in a single DCI message may correspond to a BWP number (e.g., in an ordered set of BWPs) that is greater than the number of BWPs configured for a cell in a plurality of cells scheduled by the single DCI message. For example, if a first cell scheduled by a single DCI message has four configured BWPs and a second cell scheduled by the single DCI message has two configured BWPs, the BWP indicator field may include two bits to enable indication of each of the four configured BWPs for the first cell (e.g., using four possible values ​​of 00, 01, 10, and 11). However, the second cell does not have 4 configured BWPs to correspond to each possible value in the BWP indicator field.

[0247] In some aspects, when the single BWP indicator value corresponds to a BWP number greater than the number of BWPs configured for a cell (e.g., in an ordered set of BWPs), the UE 120 and / or the base station 110 may avoid scheduling communications on the cell (e.g., may avoid transmitting or receiving scheduled communications on the cell). However, in this case, the UE 120 and / or the base station 110 may schedule communications in the cell for which the BWP indicator value is valid. Alternatively, when the single BWP indicator value corresponds to a BWP number greater than the number of BWPs configured for the cell, the UE 120 and / or the base station 110 may schedule communications on the cell in a currently active BWP for the cell (e.g., may transmit or receive scheduled communications in a currently active BWP without performing a BWP switch).

[0248] Alternatively, when a single BWP indicator value corresponds to a BWP number greater than the number of BWPs configured for a cell, the UE 120 and / or the base station 110 may schedule communications on the cell (e.g., may transmit or receive scheduled communications on the cell) in a BWP that is determined at least in part based on performing a modulo operation using the BWP indicator value and the number of BWPs configured for the cell. For example, if the BWP indicator value is 3 and the number of BWPs configured for the cell is 2, the UE 120 and / or the base station 110 may calculate 3 mod 2 = 1. The UE 120 and / or the base station 110 may interpret the BWP indicator value 3 as a value of 1, and may identify the BWP in the cell that corresponds to the value 1 (e.g., the second BWP in the ordered set of BWPs). As another example, if the BWP indicator value is 2 and the number of BWPs configured for the cell is 2, the UE 120 and / or the base station 110 may calculate 2 mod 2 = 0. UE 120 and / or base station 110 may interpret the BWP indicator value 2 as a value of 0 and may identify the BWP in the cell that corresponds to the value 0 (eg, the first BWP in the ordered set of BWPs).

[0249] Alternatively, when the single BWP indicator value corresponds to a BWP number greater than the number of BWPs configured for the cell, the UE 120 and / or the base station 110 may schedule communications (e.g., may transmit or receive scheduled communications) in a specific BWP for the cell. The specific BWP may, for example, be a BWP with a minimum BWP identifier among the number of BWPs configured for the cell or a BWP with a maximum BWP identifier among the number of BWPs configured for the cell, etc. Additionally or alternatively, the specific BWP may be, for example, a first BWP in an ordered set of BWPs including the number of BWPs configured for the cell or a last BWP in an ordered set of BWPs including the number of BWPs configured for the cell, etc.

[0250] As indicated above, Fig. 9 are provided as examples. Other examples may differ from those described herein. Fig. 9 Examples described.

[0251] Fig.10 is a diagram illustrating an example 1000 of BWP indication for multiple cells scheduled by a single DCI message in accordance with various aspects of the present disclosure.

[0252] In some aspects, a single DCI message includes multiple BWP indicator values ​​in corresponding multiple BWP indicator fields, as indicated by reference numeral 1005. In this case, each BWP indicator value may correspond to a different cell among the multiple cells scheduled by the single DCI message. Fig.10 An example single DCI message includes multiple fields (eg, two fields) dedicated to carrying respective bits of corresponding BWP indicator values. By using multiple BWP indicator fields and corresponding multiple BWP indicator values, scheduling flexibility may be increased.

[0253] In example 1000, a first BWP indicator value in a first BWP indicator field associated with a first cell (Cell 0) has a value of 0. As shown by reference numeral 1010, the first BWP indicator value of 0 indicates a first BWP (having a BWP ID of 1) on the first cell (Cell 0), which may be the first BWP in the ordered set of BWPs for the first cell. As further shown, a second BWP indicator value in a second BWP indicator field associated with a second cell (Cell 1) has a value of 1. As shown by reference numeral 1015, the second BWP indicator value of 1 indicates a second BWP (having a BWP ID of 4) on the second cell (Cell 1), which may be the second BWP in the ordered set of BWPs for the second cell. In some aspects, the same BWP ID may be used in different cells, but may represent different BWPs in those cells. Thus, the BWP IDs corresponding to the BWP indicator values ​​(and a single value) may be the same in different cells, or may be different in different cells. In some aspects, the number of bits included in the BWP indicator field for a cell may be based at least in part on the number of BWPs configured for the cell (e.g., 0 bits for one configured BWP, 1 bit for two configured BWPs, 2 bits for three or four configured BWPs, etc.).

[0254] In some aspects, the size of a single DCI message may be limited. In this case, the single DCI message may include multiple BWP indicator values ​​in the corresponding multiple BWP indicator fields only when the number of cells scheduled by the single DCI message is less than or equal to a threshold (e.g., two or three, etc.). In this way, the size limit of a single DCI message may be met.

[0255] As indicated above, Fig.10 are provided as examples. Other examples may differ from those described herein. Fig.10 Examples described.

[0256] Fig.11 is a diagram illustrating an example 1100 of BWP indication for multiple cells scheduled by a single DCI message in accordance with various aspects of the present disclosure.

[0257] As indicated by reference numeral 1105, in some aspects, a single DCI message may include a single BWP indicator value within a single BWP indicator field, which may save signaling overhead and may save network resources. In example 1100, the single BWP indicator value represents multiple values, and each of the multiple values ​​is used to identify a respective BWP for a corresponding cell. For example, as indicated by reference numeral 1110, a single BWP indicator value (shown as 1) may represent a first value (e.g., 0) identifying a first BWP for a first scheduled cell and may also represent a second value (e.g., 1) identifying a second BWP for a second scheduled cell. As indicated by reference numeral 1115, the first value 0 indicates a first BWP (with a BWP ID of 1) on a first cell (cell 0), which may be the first BWP in an ordered set of BWPs for the first cell. As shown by reference numeral 1120, a second value of 1 may indicate a second BWP (having a BWP ID of 4) on a second cell (Cell 1), which may be a second BWP in the ordered set of BWPs for the second cell.

[0258] For example, as indicated by reference numeral 1125, the base station 110 may transmit a configuration (e.g., in an RRC message) to the UE 120 indicating the number of bits to be included in a single BWP indicator field (e.g., the bit length or bit size of the field). For example, the base station 110 may indicate that the BWP indicator field is 1 bit long, 2 bits long, 3 bits long, etc. Additionally or alternatively, the base station 110 may configure a mapping between a bit value (e.g., a BWP indicator value) and a corresponding set of multiple values ​​for identifying the multiple BWPs. In example 1100, the base station 110 indicates that a BWP indicator value of 0 corresponds to a first value of 0 (for a first cell) and a second value of 0 (for a second cell), a BWP indicator value of 1 corresponds to a first value of 0 and a second value of 1, a BWP indicator value of 2 corresponds to a first value of 1 and a second value of 0, and a BWP indicator value of 3 corresponds to a first value of 1 and a second value of 1. This may enable increased scheduling flexibility while also reducing signaling overhead.
