[0003] Public domain

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

[0005] background

[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 network may include several base stations (BSs) that can support communications for several user equipments (UEs). The UE may communicate with the BS via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving 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 a common protocol that enables different user equipment to communicate at city, country, region, and even global levels. The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at city, country, region, and even global levels. 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. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful.

[0029] Detailed Description

[0030] 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 of this article, 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 independently implemented or implemented 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.

[0031] 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.

[0032] It should be noted that while 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 after 5G (e.g., 6G).

[0033] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, 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, a B node, a gNB, a 5G B node (NB), an access point, a transmit receive point (TRP), etc. 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 the coverage area, depending on the context in which the term is used.

[0034] 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.

[0035] 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 or virtual networks, using any suitable transport network.

[0036] 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 , 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, or the like.

[0037] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, 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).

[0038] 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.

[0039] 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.

[0040] 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, and / or location tags, 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), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client 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, 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, and / or electrically coupled.

[0041] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific 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.

[0042] 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 or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. 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.

[0043] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) and / or can communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) can span 410 MHz to 7.125 GHz, and the second frequency range (FR2) can span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band 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). Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz" and the like, if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave" and the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0044] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0045] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0046] 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 the UE based at least in part on the MCS selected for each 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, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective 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 upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0047] 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) 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 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.

[0048] 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.

[0049] 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. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. 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. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0050] 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, where 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 antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 5-12 As described.

[0051] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where 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 the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110.

The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 5-12 As described.

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 (e.g., code and / or program code) for wireless communication. 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 Fig.11 Process 1100, Fig.12 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0053] 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 TDRAs corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and / or means for communicating using the multiple TDRAs corresponding to the multiple cells, wherein the means for communicating includes: means for transmitting communications using the multiple TDRAs corresponding to the multiple cells, or means for receiving communications using the multiple TDRAs corresponding to the multiple cells. In some aspects, such means may include means for combining 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, and / or receive processor 258.

[0054] 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 TDRAs corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and / or means for communicating using the multiple TDRAs corresponding to the multiple cells, wherein the means for communicating includes: means for transmitting communications using the multiple TDRAs corresponding to the multiple cells, or means for receiving communications using the multiple TDRAs corresponding to the multiple cells. 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, and / or antenna 234.

[0055] although Figure 2 The blocks in the 200 and 210 are illustrated as different components, but the functions described above with respect to these blocks may be implemented with a single hardware, software, or combined component or various combinations of components. For example, the functions 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.

[0056] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0057] Figure 3 is a diagram illustrating an example time-domain resource assignment according to the present disclosure. Figure 3 An example downlink time domain resource assignment (TDRA) table 305 and an example uplink TDRA table 310 are shown. The downlink TDRA table 305 may be, for example, a physical downlink shared channel (PDSCH) TDRA table. The uplink TDRA table 310 may be, for example, a physical uplink shared channel (PUSCH) TDRA table. In some aspects, the base station 110 and the UE 120 may share information related to the TDRA table. Figure 3 Different TDRA tables than those shown in FIG. 1 may be used, such as for different configurations, different cells, different subcarrier spacing of cells, etc.

[0058] When scheduling a communication, base station 110 may transmit downlink control information (DCI) indicating the TDRA to be used for the communication. For example, the DCI may include a TDRA field including a TDRA index value. The TDRA index value may indicate a row index of a corresponding TDRA table, and the row index may correspond to a TDRA parameter set (sometimes referred to as scheduling parameters or scheduling information). Base station 110 and UE 120 may use those TDRA parameters for scheduled communications. Figure 3 In the example shown in , the TDRA index value m in the DCI may correspond to the row index m+1 in the TDRA table. For example, the TDRA index value 0 may correspond to the row index 1.

[0059] For downlink communication (e.g., PDSCH communication), TDRA parameters may include, for example, K0 values, S values, and L values. The K0 value may represent a scheduling offset (e.g., in the form of the number of time slots) between a time slot containing a scheduled DCI (for scheduling PDSCH communication) and a time slot containing a scheduled PDSCH communication (scheduled by the scheduling DCI). The S value may represent the starting symbol for PDSCH communication in the indicated time slot. The L value may represent the length (e.g., the number of consecutive symbols) of PDSCH communication (e.g., in the indicated time slot). In some aspects, the same row index value may correspond to different TDRA parameter sets depending on the type A demodulation reference signal (DMRS) position (e.g., a symbol within a resource block containing DMRS), a PDSCH mapping type (e.g., indicating the starting symbol of DMRS, the length of DMRS, and / or using slot-based scheduling or mini-slot-based scheduling), etc.

[0060] For uplink communication (e.g., PUSCH communication), TDRA parameters may include, for example, K2 values, S values, and L values. The K2 value may represent a scheduling offset (e.g., in the form of a number of slots) between a time slot containing a scheduled DCI (for scheduling PUSCH communication) and a time slot containing a scheduled PUSCH communication (scheduled by the scheduling DCI). The S value may represent the starting symbol for PUSCH communication in the indicated time slot. The L value may represent the length (e.g., the number of consecutive symbols) of PUSCH communication (e.g., in the indicated time slot). In some aspects, the same row index value may correspond to different TDRA parameter sets depending on, for example, the PUSCH mapping type (e.g., indicating the starting symbol of DMRS, the length of DMRS, and / or using slot-based scheduling or mini-slot-based scheduling).

[0061] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0062] Figure 4 4 is a diagram illustrating an example 400 of scheduling DCI (eg, a single DCI message) for multiple cells according to the present disclosure. Figure 4 As shown, base station 110 and UE 120 may communicate with each other.

[0063] As shown, the base station 110 may transmit to the UE 120 a DCI 405 (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) scheduled 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) scheduled DCI. In some aspects, the DCI 405 may be a cross-carrier scheduled DCI, and may or may not be a self-carrier scheduled DCI. In some aspects, the DCI 405 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. Different cells scheduled by the DCI 405 may have the same subcarrier spacing (SCS) or different SCSs.

[0064] In example 400, DCI 405 schedules communications for a first cell 410 (shown as CC0) that carries DCI 405, schedules communications for a second cell 415 (shown as CC1) that does not carry DCI 405, and schedules communications for a third cell 420 (shown as CC2) that does not carry DCI 405. In some aspects, DCI 405 may schedule communications with Figure 4 , (eg, two cells, four cells, five cells, etc.). The number of cells may be greater than or equal to two.

[0065] Communications scheduled by DCI 405 may include data communications, such as physical downlink shared channel (PDSCH) communications, physical uplink shared channel (PUSCH) communications, etc. For data communications, DCI 405 may schedule a single transport block (TB) across multiple cells, or may schedule multiple TBs separately in multiple cells. Additionally or alternatively, communications scheduled by DCI 405 may include reference signals, such as channel state information reference signals (CSI-RS), sounding reference signals (SRS), etc. For reference signals, DCI 405 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, scheduling information in DCI 405 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 DCI 405, resource allocations for scheduled communications, etc., to save signaling overhead.

[0066] In some aspects, the base station 110 may utilize the TDRA table to configure the cell, as described above in conjunction with Figure 3 As described. In this case, when the base station 110 transmits DCI to the UE 120 to schedule communication (e.g., uplink communication or downlink communication), the base station 110 may include in the DCI (e.g., in the TDRA field of the DCI) a TDRA index value of a TDRA parameter set (e.g., corresponding to a row index indicated by the TDRA index value) included in the TDRA table. The UE 120 may transmit or receive (e.g., monitor) communication on the cell using the indicated TDRA parameters. For example, the UE 120 may transmit or receive communication on the cell in a time slot indicated by the TDRA index value and within a time period defined by the start symbol and length indicated by the TDRA index value.

[0067] However, when a single DCI message schedules communications on multiple cells, such as Figure 4 As shown in , each cell may be associated with (e.g., configured with) a different TDRA table. In this case, UE 120 may misinterpret the TDRA index value included in a single DCI message and may select a TDRA that is not intended by base station 110. This may result in errors and dropped communications, may increase latency, may reduce reliability, may reduce spectral efficiency (e.g., due to retransmissions), etc.

[0068] Some techniques and devices described herein enable UE 120 to correctly interpret a TDRA index value included in a single DCI message that schedules communications in multiple cells, and apply the TDRA index value to determine a corresponding TDRA on each of the multiple cells. In this way, communication errors can be reduced, latency can be reduced, reliability can be increased, spectrum efficiency can be improved, etc. In addition, some techniques and devices described herein enable a single TDRA index value to be applied across multiple cells, thereby reducing signaling overhead.

[0069] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0070] Figure 5 is a diagram illustrating an example 500 of time domain resource assignment for multiple cells scheduled by a single DCI message according to the present disclosure. Figure 5 As shown, base station 110 and UE 120 may communicate with each other.

[0071] As indicated by reference numeral 505, the base station 110 may transmit TDRA configurations for multiple cells to the UE 120. For example, the base station 110 may configure one or more TDRA tables for each cell configured for the UE 120. In some aspects, the base station 110 may configure a first TDRA table for a first cell (having a cell ID of 0), and may configure a second TDRA table for a second cell (having a cell ID of 1). In some aspects, the base station 110 may configure one or more uplink TDRA tables (e.g., one or more PUSCH TDRA tables) for uplink communications on the cell, and / or one or more downlink TDRA tables (e.g., one or more PDSCH TDRA tables) for downlink communications on the cell for each cell configured for the UE 120. In some aspects, the TDRA configuration may be included in a configuration message, such as a radio resource control (RRC) message (e.g., an RRC configuration message, an RRC reconfiguration message, etc.). In some aspects, the TDRA configuration may be specified according to a wireless communication standard.

[0072] As indicated by reference numeral 510, base station 110 may transmit a single DCI message to UE 120 that schedules communications on multiple cells, as described above in conjunction with Figure 4 As described in more detail, a single DCI message may indicate multiple TDRAs corresponding to multiple cells, as indicated by reference numeral 515. Each of the multiple TDRAs may correspond to a different scheduled communication.

[0073] In example 500, a single DCI message indicates that a first communication is scheduled on a first cell (Cell 0) according to a first set of TDRA parameter values ​​(shown as A, B, and C), and a second communication is scheduled on a second cell (Cell 1) according to a second set of TDRA parameter values ​​(shown as D, E, and F). As described in more detail below, the first set of TDRA parameter values ​​may be the same as or different from the second set of TDRA parameter values. As further shown, the first TDRA parameter set may correspond to a row index X and the second TDRA parameter set may correspond to a row index Y. As described in more detail below, the row index for the first TDRA parameter set (e.g., X) may be the same as or different from the row index for the second TDRA parameter set (e.g., Y). The following is in conjunction with Figure 6-10 Additional details are described regarding techniques for indicating multiple TDRAs.

[0074] As indicated by reference numeral 520, UE 120 and base station 110 may communicate with each other using multiple TDRAs corresponding to multiple cells (indicated in a single DCI message). For example, base station 110 may transmit downlink communications (e.g., PDSCH communications) to UE 120 using multiple TDRAs corresponding to multiple cells, and UE 120 may monitor and / or receive downlink communications using multiple TDRAs corresponding to multiple cells. Alternatively, UE 120 may transmit uplink communications (e.g., PUSCH communications) to base station 110 using multiple TDRAs corresponding to multiple cells, and base station 110 may monitor and / or receive uplink communications using multiple TDRAs corresponding to multiple cells.

[0075] For example, if a single DCI message includes a downlink grant that schedules downlink communications on multiple cells, the single DCI message may indicate multiple downlink TDRAs corresponding to the multiple cells. For example, a single DCI message may include one or more TDRA index values ​​that may indicate multiple downlink TDRAs corresponding to the multiple cells. The multiple downlink TDRAs may be indicated in the same downlink TDRA table used across multiple cells, or may be indicated in different downlink TDRA tables for different cells. The base station 110 may transmit downlink communications using the indicated downlink TDRA for the respective cells, and the UE 120 may monitor and / or receive downlink communications using the indicated downlink TDRA for the respective cells.

[0076] 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 TDRAs corresponding to the multiple cells. For example, a single DCI message may include one or more TDRA index values ​​that may indicate multiple uplink TDRAs corresponding to the multiple cells. The multiple uplink TDRAs may be indicated in the same uplink TDRA table used across multiple cells, or may be indicated in different uplink TDRA tables for different cells. The base station 110 may transmit uplink communications using the indicated uplink TDRA for the respective cell, and the UE 120 may monitor and / or receive uplink communications using the indicated uplink TDRA for the respective cell.

[0077] By implementing the indication of multiple TDRAs 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 6-10 Additional details about techniques for indicating multiple TDRAs are described. In some aspects, a first technique described below may be used to indicate multiple TDRAs for downlink communications, and a second (e.g., different) technique described below may be used to indicate multiple TDRAs for uplink communications. In some aspects, the same technique may be used to indicate multiple TDRAs for both downlink and uplink communications.

[0078] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0079] Figure 6 is a diagram illustrating an example 600 of time domain resource assignment for multiple cells scheduled by a single DCI message in accordance with the present disclosure.

[0080] As indicated by reference numeral 605, in some aspects, a single DCI message includes a single TDRA index value within a single TDRA field. The term "TDRA index value" may refer to a value that indicates or identifies a TDRA to be used for scheduled communications, as described above in conjunction with Figure 3 The term "TDRA field" may refer to a field in a single DCI message that includes a TDRA index value (such as a dedicated field in a single DCI message that includes a TDRA index value). Figure 6An example single DCI message includes a single field of bits dedicated to carrying a TDRA index value. By using a single TDRA field and a single TDRA index value, signaling overhead may be reduced and network resources may be saved.

[0081] In example 600, a single TDRA index value indicates a single TDRA parameter set for multiple cells scheduled by a single DCI message in a single TDRA table. For example, a single TDRA index value (shown as 0) may indicate a single TDRA parameter set for each cell on which a single DCI message schedules communications. In some aspects, a single TDRA parameter set may correspond to a single row index of a single TDRA table. For example, as shown by reference numeral 610, a single TDRA index value of 0 indicates a row index 1 in a single TDRA table for both a first cell (cell 0) and a second cell (cell 1) scheduled by a single DCI message. In this case, the same row index and the same TDRA table are used for both the first cell and the second cell to identify the TDRA parameter set for the two cells. For example, PDSCH communications on both the first cell and the second cell may be scheduled according to a K0 value of 0, an S value of 2, and an L value of 12, as shown.

[0082] In some aspects, UE 120 may be configured with different TDRA tables for different cells. For example, UE 120 may be configured with a first TDRA table for a first cell and may be configured with a second TDRA table for a second cell. This may lead to a misinterpretation of the TDRA index value (e.g., due to a misinterpretation of which TDRA table the TDRA index value will apply to). To alleviate this problem, UE 120 may follow a rule to determine the TDRA table to be used in association with the TDRA index value indicated in a single DCI message. The rule may be configured by base station 110 or may be specified according to a wireless communication standard.

[0083] For example, as indicated by reference numeral 615, the base station 110 may transmit to the UE 120 a configuration (e.g., in an RRC message) of a TDRA table (e.g., a single TDRA table) indicating a single DCI to be used for scheduling communications on multiple cells. In some aspects, the base station 110 may configure a different TDRA table for a single DCI schedule for multiple cells than all TDRA tables configured for cells configured for the UE 120. For example, a TDRA table configured for a single DCI schedule for multiple cells may be dedicated to or used only for scheduling a single DCI message for multiple cells and may not be used for scheduling DCI for a single cell (e.g., a single DCI schedule for a single cell).

[0084] Alternatively, the base station 110 and / or the UE 120 may use a TDRA table associated with and / or configured for a specific cell, which is configured for the UE 120 for a single DCI scheduling of multiple cells. In this case, the TDRA table configured for the specific cell may be reused for a single DCI scheduling of multiple cells, thereby saving signaling overhead. The specific cell may or may not be included in the multiple cells scheduled by a single DCI message. In some aspects, the specific cell may be a cell (e.g., a scheduling cell) via which a single DCI message is received. In some aspects, the specific cell may be a cell with the smallest cell identifier or the smallest SCS among all cells of the multiple cells scheduled by a single DCI message (or the smallest cell identifier or the smallest SCS among a set of cells including the multiple cells and including the scheduling cell). In some aspects, the particular cell may be a cell among multiple cells scheduled by a single DCI message that has the largest cell identifier or the largest SCS among all cells in the multiple cells (or has the largest cell identifier or the largest SCS among a set of cells that includes the multiple cells and includes the scheduled cell).

[0085] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0086] Figure 7 is a diagram illustrating an example 700 of time domain resource assignment for multiple cells scheduled by a single DCI message in accordance with the present disclosure.

[0087] As shown by reference numeral 705, in some aspects, a single DCI message includes a single TDRA index value within a single TDRA field. By using a single TDRA field and a single TDRA index value, signaling overhead can be reduced and network resources can be saved. In example 700, a single TDRA index value indicates a plurality of TDRA parameter sets in a corresponding plurality of TDRA tables. In this case, each TDRA parameter set in the plurality of TDRA parameter sets corresponds to a different cell in a plurality of cells scheduled by a single DCI message. In some aspects, the plurality of TDRA parameter sets are associated with the same row index in different TDRA tables.

[0088] For example, as shown by reference numeral 710, a single TDRA index value of 0 may indicate a row index of 1 to be used for both a first cell (cell 0) scheduled by a single DCI message and a second cell (cell 1) scheduled by a single DCI message. As shown by reference numeral 715, the first cell may be associated with a first TDRA table (e.g., according to a configuration). As shown by reference numeral 720, the second cell may be associated with a second (e.g., different) TDRA table (e.g., according to a configuration). As shown by reference numeral 725, in some aspects, the first TDRA table and the second TDRA table may have different TDRA parameter sets associated with the same row index. As shown, row index 1 in the first TDRA table for a first cell (e.g., having a specific SCS, such as 15kHz) indicates that the K0 value is 1, the S value is 1, and the L value is 6. As further shown, a row index 1 in a second TDRA table for a second cell (e.g., having an SCS that is twice or some other multiple of the SCS of the first cell, such as 30 kHz) indicates a K0 value of 2, an S value of 2, and an L value of 12. Thus, a single TDRA index value of 0 may indicate a first TDRA parameter set for the first cell (e.g., a K0 value of 1, an S value of 1, and an L value of 6), and may indicate a second TDRA parameter set for the second cell (e.g., a K0 value of 2, an S value of 2, and an L value of 12). In this way, communications on different cells with different SCSs may be time-aligned (e.g., having the same start time and the same duration).

[0089] In some aspects, UE 120 may be configured with different TDRA tables for different cells, and those different TDRA tables may have different numbers of rows. For example, UE 120 may be configured with a first TDRA table including a first number of rows for a first cell, and may be configured with a second TDRA table including a second number of rows for a second cell. The number of rows may be the same or different in different TDRA tables. If different TDRA tables have different numbers of rows, this may lead to a misinterpretation of the TDRA index 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 TDRA field (e.g., the number of bits of the TDRA index value). The rule may be configured by base station 110 or may be specified according to a wireless communication standard.

[0090] For example, as indicated by reference numeral 730, 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 TDRA field (e.g., the bit length, bit width, or bit size of the field). For example, the base station 110 may indicate that the TDRA field is 1 bit long, 2 bits long, 3 bits long, or 4 bits long, etc. Alternatively, the base station 110 may indicate a manner of determining the number of bits. In some aspects, the number of bits (e.g., bit length, bit width, or bit size) or the manner of determining the number of bits may be specified in a wireless communication standard.

[0091] In some aspects, the number of bits included in the TDRA field of a single DCI message may be based at least in part on the number of rows in the TDRA configured for the cell on which the communication is scheduled by the single DCI message (e.g., for any cell). In some aspects, all cells scheduled by a single DCI message may need to be configured with a TDRA table having the same number of rows (e.g., the same number of rows of the downlink TDRA table for a single DCI that schedules downlink communications, or the same number of rows of the uplink TDRA table for a single DCI that schedules uplink communications). For example, if all of the multiple cells scheduled by a single DCI message have a TDRA table with 16 rows (sometimes referred to as entries), the TDRA field may contain 4 bits. As another example, if all of the multiple cells scheduled by a single DCI message have a TDRA table with 8 rows, the TDRA field may contain 3 bits. This reduces the possibility of ambiguity when scheduling communications on multiple cells.

[0092] In some aspects, the number of bits included in the TDRA field of a single DCI message may be based at least in part on the maximum number of rows permitted in the TDRA table. For example, if a maximum of 16 rows are permitted to be included in the TDRA table (e.g., if the TDRA table is not permitted to be configured with more than 16 rows), the TDRA field may include four bits.

[0093] In some aspects, the number of bits included in the TDRA field of a single DCI message may be based at least in part on a minimum number of rows in a TDRA table configured for a cell in the plurality of cells as compared to all other TDRA tables configured for the cells scheduled by the single DCI message. For example, if a first cell scheduled by a single DCI message is associated with a TDRA table having 16 rows, and a second cell scheduled by the single DCI message is associated with a TDRA table having 8 rows, the TDRA field may include three bits (e.g., to indicate 8 possible values, one for each row of the TDRA table for the second cell). This may reduce signaling overhead.

[0094] In some aspects, the number of bits included in the TDRA field of a single DCI message may be based at least in part on the maximum number of rows in the TDRA table configured for a cell in the multiple cells as compared to all other TDRA tables configured for the multiple cells scheduled by the single DCI message. For example, if a first cell scheduled by a single DCI message is associated with a TDRA table having 16 rows, and a second cell scheduled by the single DCI message is associated with a TDRA table having 8 rows, the TDRA field may include four bits (e.g., to indicate 16 possible values, one for each row of the TDRA table for the first cell). This may increase scheduling flexibility.

[0095] In some aspects, the number of bits included in the TDRA field of a single DCI message may be based at least in part on the number of rows in the TDRA table configured for a particular cell. A particular cell may or may not be included in a plurality of cells scheduled by a single DCI message. In some aspects, a particular cell may be a cell (e.g., a scheduling cell) via which a single DCI message is received. In some aspects, a particular cell may be a cell with the minimum cell identifier or minimum SCS among all cells of the plurality of cells scheduled by a single DCI message (or with the minimum cell identifier or minimum SCS among a set of cells including the plurality of cells and including the scheduling cell). In some aspects, a particular cell may be a cell with the maximum cell identifier or maximum SCS among all cells of the plurality of cells scheduled by a single DCI message (or with the maximum cell identifier or maximum SCS among a set of cells including the plurality of cells and including the scheduling cell).

[0096] In some aspects, a single TDRA value included in a single DCI message may correspond to a row index (e.g., a row index value) that is greater than the number of rows in a TDRA table configured for a cell among a plurality of cells scheduled by the single DCI message. For example, if a first cell scheduled by a single DCI message is associated with a TDRA table having 16 rows, and a second cell scheduled by the single DCI message is associated with a TDRA table having 8 rows, the TDRA field may include four bits to enable an indication of each of the 16 rows of the TDRA table configured for the first cell. However, the second cell does not have 16 rows in the associated TDRA table to correspond to every possible value in the TDRA field.

[0097] In some aspects, when a single TDRA value corresponds to a row index greater than the number of rows in the TDRA table configured for a cell, the UE 120 and / or base station 110 may avoid scheduling communications on the cell (e.g., may refrain from transmitting or receiving scheduled communications on the cell). However, in this case, the UE 120 and / or base station 110 may schedule communications in the cell for which the TDRA index value is valid.

[0098] Alternatively, when a single TDRA value corresponds to a row index greater than the number of rows in the TDRA table configured for the 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) using a TDRA that is determined at least in part based on a modulo operation performed using the TDRA index value and the number of rows in the TDRA table configured for the cell. For example, if the TDRA index value is 10 and the number of rows in the TDRA table configured for the cell is 8, the UE 120 and / or the base station 110 may calculate 10mod 8=2. The UE 120 and / or the base station 110 may interpret the TDRA index value 10 as a value 2, and may identify a TDRA (e.g., a TDRA parameter set) for a cell corresponding to a value 2 (e.g., a row index 2 or a TDRA index value 2 corresponding to a row index 3, etc.).

[0099] Alternatively, when a single TDRA value corresponds to a row index greater than the number of rows in the TDRA table configured for the cell, the UE 120 and / or the base station 110 may schedule communications (e.g., may transmit or receive scheduled communications) using a specific TDRA (e.g., a specific TDRA parameter set) for the cell. The specific TDRA may be, for example, a TDRA included in the first row of the TDRA table configured for the cell (e.g., a TDRA indicated by row index 1) or a TDRA included in the last row of the TDRA table configured for the cell, etc.

[0100] As indicated above, Figure 7 are provided as examples. Other examples may differ from those described herein. Figure 7 Examples described.

[0101] Figure 8 is a diagram illustrating an example 800 of time domain resource assignment for multiple cells scheduled by a single DCI message in accordance with the present disclosure.

[0102] In some aspects, a single DCI message includes multiple TDRA index values ​​in corresponding multiple TDRA fields, as indicated by reference numeral 805. In this case, each TDRA index value may correspond to a different cell among the multiple cells scheduled by the single DCI message. Figure 8 An example single DCI message includes multiple fields (eg, two fields) dedicated to carrying respective bits of corresponding TDRA index values. By using multiple TDRA fields and corresponding multiple TDRA index values, scheduling flexibility may be increased.

[0103] In example 800, a first TDRA index value in a first TDRA field associated with a first cell (cell 0) has a value of 0. As shown by reference numeral 810, a first TDRA index value of 0 indicates a first TDRA parameter set for a first cell (cell 0), which may be associated with a row index 1 in a TDRA table configured for the first cell. As further shown, a second TDRA index value in a second TDRA field associated with a second cell (cell 1) has a value of 1. As shown by reference numeral 815, a second TDRA index value of 1 indicates a second TDRA parameter set for a second cell (cell 1), which may be associated with a row index 2 in a TDRA table configured for the second cell. In some aspects, the same TDRA table may be configured for different cells. In some aspects, different TDRA tables may be configured for different cells. In some aspects, one or more row indexes of different TDRA tables may be associated with the same TDRA parameter set. In some aspects, one or more row indexes of different TDRA tables may be associated with different TDRA parameter sets. In some aspects, the number of bits included in the TDRA field for a cell may be based at least in part on the number of rows of the TDRA table configured for the cell (e.g., 2 bits for four rows, 3 bits for eight rows, 4 bits for 16 rows, etc.).

[0104] In some aspects, the size of a single DCI message may be limited. In this case, the single DCI message may include multiple TDRA index values ​​in the corresponding multiple TDRA fields only when the number of cellular cells scheduled by the single DCI message is less than or equal to a threshold (e.g., two, etc.). In this way, the size limit of a single DCI message can be met.

[0105] As indicated above, Figure 8 are provided as examples. Other examples may differ from those described herein. Figure 8 Examples described.

[0106] Fig. 9 is a diagram illustrating an example 900 of time domain resource assignment for multiple cells scheduled by a single DCI message in accordance with the present disclosure.

[0107] As shown by reference numeral 905, in some aspects, a single DCI message may include a single TDRA index value within a single TDRA field, which can save signaling overhead and can save network resources. In example 900, a single TDRA index value indicates multiple TDRA parameter sets associated with a single row index of a single TDRA table. Each TDRA parameter set in a plurality of TDRA parameter sets may correspond to a different cell in a plurality of cells scheduled by a single DCI message. For example, as shown by reference numeral 910, a single TDRA index value (shown as 0) may indicate a first TDRA parameter set 915 (e.g., K2 value is 0, S value is 0, and L value is 14) for a first scheduled cell (e.g., cell 0), and may also indicate a second TDRA parameter set 920 (e.g., K2 value is 0, S value is 0, and L value is 7) for a second scheduled cell (e.g., cell 1). The first TDRA parameter set and the second TDRA parameter set may be included in a single TDRA table 925. In some aspects, the number of bits in the TDRA field is based at least in part on the number of rows in the single TDRA table 925 .

[0108] As indicated by reference numeral 930, the base station 110 may transmit a configuration (e.g., in an RRC message) to the UE 120 indicating a mapping of scheduled cells and TDRA parameter sets. In example 900, the base station 110 indicates that a first TDRA parameter set associated with a row index (shown as TDRA parameters associated with a "first" cell in the TDRA table 925) is mapped to cell 0, and a second TDRA parameter set associated with the row index (shown as TDRA parameters associated with a "second" cell in the TDRA table 925) is mapped to cell 1. In some aspects, rather than mapping TDRA parameter sets associated with the same row index to a particular cell, the configuration may indicate a mapping based at least in part on the cell identifiers of the scheduled cells. For example, the cell with the lowest cell identifier may be mapped to the first TDRA parameter set associated with the row index, the cell with the next lowest cell identifier (or the highest cell identifier, in the case of two scheduled cells) may be mapped to the second TDRA parameter set associated with the row index, and so on. In some aspects, this mapping may be specified in a wireless communication standard. This may enable increased scheduling flexibility while also reducing signaling overhead.

[0109] As indicated above, Fig. 9 are provided as examples. Other examples may differ from those described herein. Fig. 9 Examples described.

[0110] Fig.10is a diagram illustrating an example 1000 of time domain resource assignment for multiple cells scheduled by a single DCI message in accordance with the present disclosure.

[0111] As shown by reference numeral 1005, in some aspects, a single DCI message includes a single TDRA index value within a single TDRA field, which can reduce signaling overhead and save network resources. In example 1000, a single TDRA index value indicates a single TDRA parameter set for a reference cell in a single TDRA table. In some aspects, a single TDRA parameter set may correspond to a single row index of a single TDRA table 1010. A single TDRA table 1010 may be a TDRA table configured for a reference cell. For example, as shown by reference numeral 1015, a single TDRA index value 0 indicates a row index 1 in a single TDRA table 1010 configured for a reference cell. For example, communications on a reference cell may be scheduled according to a K0 value of 1, an S value of 1, and an L value of 6, as shown.

[0112] The reference cell may or may not be included in the multiple cells scheduled by the single DCI message. In some aspects, the reference cell may be a cell (e.g., a scheduling cell) via which the single DCI message is received. In some aspects, the reference cell may be a cell with the minimum cell identifier or the minimum SCS among all cells of the multiple cells scheduled by the single DCI message (or with the minimum cell identifier or the minimum SCS among a set of cells including the multiple cells and including the scheduling cell). In some aspects, the reference cell may be a cell with the maximum cell identifier or the maximum SCS among all cells of the multiple cells scheduled by the single DCI message (or with the maximum cell identifier or the maximum SCS among a set of cells including the multiple cells and including the scheduling cell). In some aspects, the reference cell may be configured by the base station 110. In some aspects, the reference cell may be specified according to a wireless communication standard.

[0113] As indicated by reference numeral 1020, the UE 120 (and / or the base station 110) may determine a TDRA parameter set for cells other than the reference cell in the plurality of cells scheduled by the single DCI message. For example, the UE 120 (and / or the base station 110) may determine a TDRA parameter set for scheduled cells other than the reference cell (e.g., for non-reference cells) based at least in part on performing a calculation using the one or more modified parameters determined for the reference cell and the single TDRA parameter set. The calculation may include, for example, applying an offset to parameters in the single TDRA parameter set (e.g., applying an offset of 1 to a K0 value of 1 for the reference cell to determine a K0 value of 2 for the non-reference cell, etc.), applying a scaling factor to parameters in the single TDRA parameter set (e.g., applying a scaling factor of 2 to an S value of 1 for the reference cell to determine an S value of 2 for the non-reference cell, or applying a scaling factor of 2 to an L value of 6 for the reference cell to determine an L value of 12 for the non-reference cell, etc.), and the like.

[0114] As indicated by reference numeral 1025, in some aspects, one or more modification parameters (e.g., offset, scaling factor, etc.) may be indicated in a configuration from base station 110. In some aspects, the one or more modification parameters may be specified according to a wireless communication standard. In this way, signaling overhead may be reduced while also achieving scheduling flexibility.

[0115] As indicated above, Fig.10 are provided as examples. Other examples may differ from those described herein. Fig.10 Examples described.

[0116] Fig.11 is a diagram illustrating an example process 1100 performed, for example, by a UE in accordance with the present disclosure.

For example, a UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may receive a single DCI message that schedules communications on multiple cells, as described above. In some aspects, the single DCI message indicates multiple TDRAs corresponding to the multiple cells. In some aspects, each of the multiple TDRAs corresponds to a different scheduled communication.
