[0086] the term

[0087] The following is a glossary of terms that will appear in this application:

[0088] Memory Medium – Any of various types of memory devices or storage devices. The term “memory medium” is intended to include installation media, such as CD-ROMs, floppy disks, or tape devices; computer system memory or random access memory, such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory, such as flash memory, magnetic media, such as hard drives or optical storage devices; registers, or other similar types of memory elements, etc. Memory media may also include other types of memory or combinations thereof. Furthermore, a memory medium may be located in a first computer system executing a program, or in a second, different computer system connected to the first computer system via a network, such as the Internet. In the latter example, the second computer system may provide program instructions to the first computer system for execution. The term “memory medium” may include two or more memory media that may reside in different locations, such as in different computer systems connected via a network.

[0089] Carrier Medium—storage media as described above, and physical transmission media such as a bus, network, and / or other physical transmission media that transport signals such as electrical, electromagnetic, or digital signals.

[0090] Computer system (or computer)—any of various types of computing or processing systems, including a personal computer system (PC), a mainframe computer system, a workstation, a network appliance, an Internet appliance, a personal digital assistant (PDA), a television system, a grid computing system, or other devices or combinations of devices. In general, the term "computer system" can be broadly defined as any device (or combination of devices) that includes at least one processor that executes instructions from a memory medium.

[0091] User Equipment (UE) (or "UE device") - any of various types of computer system devices that perform wireless communications. Also known as wireless communication devices, many of which may be mobile and / or portable. Examples of UE devices include mobile phones or smartphones (e.g., iPhones). TM , based on Android TM phones) and tablets such as iPads TM 、Samsung Galaxy TM etc., gaming devices (such as Sony PlayStation TM , Microsoft XBox TM etc.), portable gaming devices (e.g., Nintendo DS TM PlayStation Portable TM 、Gameboy AdvanceTM iPod TM ), laptops, wearable devices (e.g., Apple Watch TM , Google Glass TM ), PDAs, portable internet devices, music players, data storage devices or other handheld devices, etc. Various other types of devices may include Wi-Fi communication capabilities or both cellular and Wi-Fi communication capabilities and / or other wireless communication capabilities (e.g., via short-range radio access technologies (SRAT) such as BLUETOOTH TM In general, the term "UE" or "UE device" can be broadly defined to cover any electronic device, computing device and / or telecommunication device (or combination of devices) capable of wireless communication and which may also be portable / mobile.

[0092] Base Station (BS)—The term “base station” has the full breadth of its ordinary meaning and includes at least a wireless communication station that is installed at a fixed location and used to communicate as part of a wireless telephone system or radio system.

[0093] Processing Element—refers to various elements or combinations of elements that are capable of performing one or more functions in a device (e.g., in a user equipment device or in a cellular network device) and / or enabling the user equipment device or cellular network device to perform one or more functions. A processing element may include, for example, a processor and associated memory, portions or circuits of individual processor cores, entire processor cores, processor arrays, circuits such as ASICs (Application Specific Integrated Circuits), programmable hardware elements such as field programmable gate arrays (FPGAs), and any of the above combinations.

[0094] Wireless device (or wireless communication device)—any of various types of computer system devices that perform wireless communication using WLAN communication, SRAT communication, Wi-Fi communication, etc. As used herein, the term "wireless device" can refer to a UE device as defined above or a fixed device such as a fixed wireless client or a wireless base station. For example, a wireless device can be a wireless station of any type of 802.11 system, such as an access point (AP) or a client station (UE), or a wireless station of any type of cellular communication system that communicates according to a cellular radio access technology (e.g., LTE, CDMA, GSM), such as a base station or a cellular phone.

[0095] Wi-Fi—The term "Wi-Fi" has the full scope of its ordinary meaning and includes at least wireless communication networks, or RATs, that are served by wireless LAN (WLAN) access points and provide connectivity to the Internet through those access points. Most modern Wi-Fi networks (or WLAN networks) are based on the IEEE 802.11 standard and are marketed under the "Wi-Fi" name. Wi-Fi (WLAN) networks are distinct from cellular networks.

[0096] Automatic—refers to an action or operation performed by a computer system (e.g., software executed by the computer system) or a device (e.g., a circuit, a programmable hardware element, an ASIC, etc.) without requiring user input to directly specify or execute the action or operation. Thus, the term "automatic" is in contrast to manual execution or specification of an action by a user, where the user provides input to directly execute the action. An automatic process may be initiated by input provided by a user, but the subsequent actions performed "automatically" are not specified by the user, i.e., they are not performed "manually," where the user specifies each action to be performed. For example, a user filling out an electronic form by selecting each field and providing input specifying information (e.g., by typing information, selecting checkboxes, selecting radios, etc.) is not manually filling out the form, even though the computer system must update the form in response to the user's actions. The form can be automatically filled out by a computer system, where the computer system (e.g., software executed on the computer system) analyzes the fields of the form and fills it out without requiring any user input to specify the answers to the fields. As indicated above, a user can invoke automatic filling of a form without participating in the actual filling out of the form (e.g., the user does not manually specify the answers to the fields; they are automatically completed). This specification provides various examples of operations that are automatically performed in response to actions that a user has taken.

[0097] Station (STA)—The term "station" herein refers to any device capable of communicating wirelessly (e.g., using the 802.11 protocol). A station can be a laptop, desktop PC, PDA, access point, or Wi-Fi phone, or any other type of device similar to a UE. A STA can be fixed, mobile, portable, or wearable. Generally speaking, in wireless networking terminology, a station (STA) broadly encompasses any device capable of wireless communication, and the terms station (STA), wireless client (UE), and node (BS) are often used interchangeably.

[0098] Configured to—Various components may be described as being “configured to” perform one or more tasks. In such contexts, “configured to” is a broad term that generally means “having structure” to perform one or more tasks during operation. Thus, a component can be configured to perform a task even when the component is not currently performing the task (e.g., a set of electrical conductors can be configured to electrically connect a module to another module even when the two modules are not connected). In some contexts, “configured to” may be a broad term that generally means “having circuitry” to perform one or more tasks during operation. Thus, a component can be configured to perform a task even when the component is not currently turned on. Generally, the circuitry that forms the structure corresponding to “configured to” may include hardware circuitry.

[0099] For ease of description, various components may be described as performing one or more tasks. Such descriptions should be interpreted as including the phrase "configured to." Representing a component as being configured to perform one or more tasks expressly does not invoke the interpretation of 35 U.S.C. §112, sixth paragraph, for that component.

[0100] Figure 1 and Figure 2 -Exemplary Communication System

[0101] Figure 1 An exemplary (and simplified) wireless communication system according to some embodiments is shown. Note that Figure 1 The system is only one example of a possible system, and embodiments may be implemented in any of a variety of systems as desired.

[0102] As shown, the exemplary wireless communication system includes a base station 102 that communicates with one or more user equipment 106A to 106N via a transmission medium. Each user equipment may be referred to herein as a "user device" (UE) or UE device. Therefore, user equipment 106 is referred to as a UE or UE device.

[0103] Base station 102 may be a base transceiver station (BTS) or a cell site and may include hardware that enables wireless communication with UEs 106A to 106N. Base station 102 may also be configured to communicate with network 100 (e.g., a cellular service provider's core network, a telecommunications network such as the Public Switched Telephone Network (PSTN), and / or the Internet, a neutral host or various CBRS deployments, among other possibilities). Thus, base station 102 may facilitate communication between user devices and / or between user devices and network 100. The communication area (or coverage area) of a base station may be referred to as a "cell." It should also be noted that a "cell" may also refer to a logical identity for a given coverage area at a given frequency. Generally, any independent cellular wireless coverage area may be referred to as a "cell." In such a case, a base station may be located at a specific intersection of three cells. In this uniform topology, a base station may serve three 120-degree beamwidth areas, referred to as cells. Furthermore, for carrier aggregation, small cells, relays, and the like may all represent cells. Thus, particularly in carrier aggregation, there may be primary cells and secondary cells that may serve at least partially overlapping coverage areas but on different respective frequencies. For example, a base station may serve any number of cells, and the cells served by a base station may or may not be collocated (e.g., a remote radio head). Also as used herein, with respect to a UE, a base station may sometimes be considered to represent a network in light of the UE's uplink and downlink communications. Thus, a UE communicating with one or more base stations in a network may also be interpreted as a UE communicating with the network.

[0104] Base station 102 and user equipment can be configured to communicate over a transmission medium using any of a variety of radio access technologies (RATs), also known as wireless communication technologies or telecommunication standards, such as GSM, UMTS (WCDMA), LTE, LTE-Advanced (LTE-A), LAA / LTE-U, 5G-NR (abbreviated as NR), 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), Wi-Fi, WiMAX, and the like. For convenience, depending on a given application or specific considerations, some of the various different RATs may be functionally grouped according to generally defined characteristics. For example, all cellular RATs may be collectively considered to represent a first (form / type) RAT, while Wi-Fi communication may be considered to represent a second RAT. In other cases, each cellular RAT may be individually considered a different RAT. For example, when distinguishing between cellular communication and Wi-Fi communication, "first RAT" may collectively refer to all cellular RATs under consideration, while "second RAT" may refer to Wi-Fi. Similarly, different forms of Wi-Fi communications (e.g., over 2.4 GHz versus over 5 GHz) can be considered to correspond to different RATs, where applicable. Furthermore, cellular communications performed according to a given RAT (e.g., LTE or NR) can be distinguished from one another based on the spectrum over which those communications occur. For example, LTE or NR communications can be performed on a primary licensed spectrum as well as on a secondary spectrum, such as an unlicensed spectrum. In general, the use of various terms and expressions will always be clearly noted with respect to and within the context of the various applications / implementations being considered.

[0105] As described above, the UE 106 may be capable of communicating using multiple wireless communication standards. For example, the UE 106 may be configured to communicate using any or all of the 3GPP cellular communication standards (such as LTE or NR) or 3GPP2 cellular communication standards (such as a cellular communication standard in the CDMA2000 family of cellular communication standards). The base station 102 and other similar base stations operating according to the same or different cellular communication standards may thus be provided as one or more cell networks that may provide continuous or nearly continuous overlapping services to the UE 106 and similar devices over a wide geographic area via one or more cellular communication standards.

[0106] UE 106 may also or alternatively be configured to use WLAN, BLUETOOTH TM 、BLUETOOTH TMThe system may communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., ATSC-M / H or DVB-H), etc. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0107] Figure 2 An exemplary user device 106 (e.g., one of devices 106-1 to 106-N) communicating with a base station 102 according to some embodiments is shown. UE 106 may be a device with wireless network connectivity, such as a mobile phone, handheld device, computer or tablet, or substantially any type of wireless device. UE 106 may include a processor configured to execute program instructions stored in a memory. UE 106 may execute any of the method embodiments described herein by executing such stored instructions. Alternatively or in addition, UE 106 may include a programmable hardware element, such as an FPGA (field programmable gate array) configured to execute any of the method embodiments described herein or any part of any of the method embodiments described herein. UE 106 may be configured to communicate using any one of a plurality of wireless communication protocols. For example, UE 106 may be configured to communicate using two or more of CDMA2000, LTE, LTE-A, NR, WLAN, or GNSS. Other combinations of wireless communication standards are also possible.

[0108] UE 106 may include one or more antennas for communicating according to one or more RAT standards using one or more wireless communication protocols. In some embodiments, UE 106 may share one or more portions of a receive chain and / or transmit chain between multiple wireless communication standards. The shared radio component may include a single antenna, or may include multiple antennas for performing wireless communication (e.g., for MIMO). Alternatively, UE 106 may include an independent transmit chain and / or receive chain (e.g., including independent antennas and other radio components) for each wireless communication protocol with which it is configured to communicate. As another alternative, UE 106 may include one or more radio components shared between multiple wireless communication protocols, and one or more radio components used exclusively by a single wireless communication protocol. For example, UE 106 may include a shared radio component for communicating using one of LTE or CDMA2000 1xRTT or NR, and a shared radio component for communicating using Wi-Fi and BLUETOOTH. TM Independent radio components for each of the communications. Other configurations are also possible.

For example, as shown, the SOC 300 may include one or more processors 302 that can execute program instructions for the UE 106, and a display circuit 304 that can perform graphics processing and provide display signals to a display 360. The one or more processors 302 may also be coupled to a memory management unit (MMU) 340, and / or other circuits or devices (such as display circuit 304, radio circuit 330, connector I / F 320 and / or display 360). The MMU may be configured to receive addresses from the one or more processors 302 and convert those addresses into locations in a memory (e.g., memory 306, read-only memory (ROM) 350, NAND flash memory 310).

The UE device 106 may include at least one antenna (e.g., 335a), and may include multiple antennas (e.g., as shown by antennas 335a and 335b) for performing wireless communications with base stations and / or other devices. Antennas 335a and 335b are shown by way of example, and the UE device 106 may include fewer or more antennas. In general, the one or more antennas are collectively referred to as one or more antennas 335. For example, the UE device 106 may use one or more antennas 335 to perform wireless communications with the radio circuit 330. As described above, in some embodiments, the UE may be configured to perform wireless communications using multiple wireless communication standards.

[0112] The one or more processors 302 of the UE device 106 may be configured to implement part or all of the methods described herein, for example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). In other embodiments, the one or more processors 302 may be configured as programmable hardware elements, such as an FPGA (field programmable gate array) or as an ASIC (application-specific integrated circuit). In addition, the one or more processors 302 may be coupled to a processor such as a processor 106. Figure 3 Other components are shown and / or may interoperate with these other components, for example, to operate in accordance with various embodiments disclosed herein. The one or more processors 302 may also implement various other applications and / or end-user applications running on the UE 106.

[0113] In some embodiments, the radio 300 may include separate controllers dedicated to controlling communications for various corresponding RAT standards.

TM Controller 354, and in at least some embodiments, one or more or all of these controllers may be implemented as respective integrated circuits (ICs or chips) that communicate with each other and with SOC 300 (more specifically, with one or more processors 302). For example, Wi-Fi controller 356 may communicate with cellular controller 352 via a cell-ISM link or WCI interface, and / or BLUETOOTH TM Controller 354 may communicate with cellular controller 352 via a cell-ISM link, etc. Although three separate controllers are shown within radio circuitry 330, other embodiments have fewer or more similar controllers implemented in UE device 106 for various different RATs.

[0118] Figure 5 —Block diagram of cellular communication circuit

[0119] Figure 5 1 shows an exemplary simplified block diagram of cellular communication circuit 330 according to some embodiments. Note that Figure 5 The block diagram of the cellular communication circuitry is merely one example of one possible cellular communication circuitry; other circuitry, such as circuitry that includes or is coupled to sufficient antennas for different RATs to perform uplink activities using separate antennas, or circuitry that includes or is coupled to fewer antennas, e.g., circuitry that can be shared between multiple RATs, is also possible. According to some embodiments, the cellular communication circuitry 330 may be included in a communication device such as the communication device 106 described above. As described above, the communication device 106 may be a user equipment (UE) device, a mobile device or station, a wireless device or station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet, and / or a combination of devices, among other devices.

In some embodiments, the cellular communication circuitry 330 may include dedicated receive chains (including and / or (e.g., communicatively; directly or indirectly) coupled to dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G NR). For example, Figure 5 As shown, the cellular communication circuit 330 may include a first modem 510 and a second modem 520. The first modem 510 may be configured for communication according to a first RAT (e.g., such as LTE or LTE-A), and the second modem 520 may be configured for communication according to a second RAT (e.g., such as 5G NR).

[0121] As shown, the first modem 510 may include one or more processors 512 and a memory 516 in communication with the processor 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuitry for transmitting and receiving radio signals. For example, the RF front end 530 may include receive circuitry (RX) 532 and transmit circuitry (TX) 534. In some embodiments, the receive circuitry 532 may communicate with a downlink (DL) front end 550, which may include circuitry for receiving radio signals via antenna 335a.

[0122] Similarly, the second modem 520 may include one or more processors 522 and a memory 526 in communication with the processor 522. The modem 520 may communicate with an RF front end 540. The RF front end 540 may include circuitry for transmitting and receiving radio signals. For example, the RF front end 540 may include receive circuitry 542 and transmit circuitry 544. In some embodiments, the receive circuitry 542 may communicate with a DL front end 560, which may include circuitry for receiving radio signals via the antenna 335b.

[0123] In some embodiments, the switch 570 can couple the transmit circuitry 534 to the uplink (UL) front end 572. Furthermore, the switch 570 can couple the transmit circuitry 544 to the UL front end 572. The UL front end 572 can include circuitry for transmitting radio signals via the antenna 336. Thus, when the cellular communication circuitry 330 receives an instruction to transmit according to a first RAT (e.g., via a transmit chain including the transmit circuitry 534 and the UL front end 572), the switch 570 can be switched to a first state that allows the first modem 510 to transmit signals according to the first RAT (e.g., via a transmit chain including the transmit circuitry 534 and the UL front end 572). Similarly, when the cellular communication circuitry 330 receives an instruction to transmit according to a second RAT (e.g., via a transmit chain including the transmit circuitry 544 and the UL front end 572), the switch 570 can be switched to a second state that allows the second modem 520 to transmit signals according to the second RAT (e.g., via a transmit chain including the transmit circuitry 544 and the UL front end 572).

[0124] As described herein, the first modem 510 and / or the second modem 520 may include hardware and software components for implementing any of the various features and techniques described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processors 512, 522 may be configured to implement some or all of the features described herein. Alternatively (or in addition), the processors 512, 522 may be configured as programmable hardware elements, such as an FPGA (field programmable gate array) or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 530, 532, 534, 540, 542, 544, 550, 570, 572, 335, and 336, the processors 512, 522 may be configured to implement some or all of the features described herein.

[0125] Furthermore, as described herein, processors 512, 522 may include one or more processing elements. Thus, processors 512, 522 may include one or more integrated circuits (ICs) configured to perform the functions of processors 512, 522. Furthermore, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processors 512, 522.

[0126] In some embodiments, the cellular communication circuit 330 may include only one transmit / receive chain. For example, the cellular communication circuit 330 may not include the modem 520, the RF front end 540, the DL front end 560, and / or the antenna 335b. For another example, the cellular communication circuit 330 may not include the modem 510, the RF front end 530, the DL front end 550, and / or the antenna 335a. In some embodiments, the cellular communication circuit 330 may also not include the switch 570, and the RF front end 530 or the RF front end 540 may communicate with the UL front end 572, for example, directly.

[0127] Figures 6 to 8 - Cross-slot scheduling

[0128] Some wireless standards (e.g., NR) may allow for variable time intervals between control information and corresponding data. The control information may correspond to data (e.g., uplink and / or downlink data) to be transmitted as control information during various time periods (e.g., in the same time slot or during a later time slot). For example, in NR, cross-slot scheduling may refer to a base station transmitting control information (e.g., a physical downlink control channel (PDCCH)) during a first time slot for corresponding data (e.g., a physical downlink shared channel (PDSCH)) during a later time slot. Same-slot scheduling may also be allowed. In other words, a PDCCH or other control information transmitted in a first time slot may correspond to data transmitted in the same time slot (e.g., same-slot scheduling) or in a later time slot (e.g., cross-slot scheduling).

[0129] Cross-slot scheduling can achieve certain advantages over same-slot scheduling. For example, cross-slot scheduling can achieve power savings at the UE. The UE can achieve such power savings by shutting down (or powering off) one or more radio frequency (RF) components of the UE immediately after receiving control information (e.g., before decoding the PDCCH and / or downlink control information (DCI)), and keeping the components shut down (or powered off) until needed to receive corresponding data or further control information. In addition, the UE can power off one or more baseband components. For example, the wireless device can power off / turn off at least certain receive circuitry, such as one or more receiver chains. If a grant is not present in a data period, the wireless device can shut down / power off the RF components for the duration of the time period (e.g., PDSCH) during which data is transmitted. The UE can turn on the RF components for future control information periods and / or for future data periods based on the control information.

[0130] In addition, cross-slot scheduling can promote design simplification and power savings by allowing time gaps between PDCCH and PDSCH (e.g., other time periods for control information and data, respectively). Based on the decoded control information, the UE can configure changes (e.g., in antenna and / or other hardware configurations) for receiving PDSCH relative to the PDCCH during the time gap. For example, the UE can use one or more of different beams or different antenna elements to receive the PDSCH. For example, the PDCCH can use a single-layer receive configuration, while the PDSCH can use a multi-layer receive configuration, among other possibilities. Moreover, the PDCCH can use a wider beam (e.g., which can provide more robustness), while the PDSCH can use a narrower beam (e.g., higher throughput). Similarly, due to changes in the position / orientation of the device, it may be beneficial for the UE to receive the PDSCH using a different directional receive beam relative to that used by the PDCCH. The gap can allow time for such configuration changes. In contrast, according to some embodiments, single-slot scheduling can be beneficial for delay-sensitive applications.

[0131] Various parameters (e.g., scheduling parameters) may be used to configure cross-slot scheduling, in particular the time interval (e.g., delay) between control information and corresponding data (e.g., payload data of an application, or possibly further control information). For example, in NR, the parameter K0 may be defined as the distance (e.g., in time) between a PDCCH and a corresponding PDSCH measured in a slot. For example, a K0 equal to 0 may indicate same-slot scheduling, and a K0 greater than 0 may indicate cross-slot scheduling, e.g., a PDCCH and its corresponding PDSCH are not scheduled at the same slot. For example, a K0 equal to 2 may indicate cross-slot scheduling, where the corresponding data transmission (uplink and / or downlink) occurs two slots later.

[0132] According to some embodiments, a set of possible delay values (e.g., K0 values) may be configured by a higher layer (e.g., radio resource control (RRC)). For example, the network may configure a set of possible delays (e.g., K0 values) during RRC setup. In some embodiments, K0=0 may generally be included as one of multiple options in such a set.

[0133] However, the delay for a particular time slot (e.g., a transmission time interval (TTI)) may be transmitted in downlink control information (DCI), for example, via the PDCCH. Therefore, if the set of possible delay values includes both a cross-slot (e.g., K0>0) possibility and a same-slot (e.g., K0=0) possibility, the UE may not be sure whether the time slot is cross-slot scheduled or same-slot scheduled until the DCI is decoded. In other words, the UE may not be able to eliminate the possibility of same-slot scheduling before decoding the DCI. The time to decode the DCI / PDCCH may be referred to as decoding delay.

[0134] The inability to eliminate the possibility of same-slot scheduling before decoding the DCI can undermine the benefits of cross-slot scheduling. For example, the UE may remain awake (e.g., rather than powering down components) until the DCI is decoded (e.g., because the UE must be able to receive the PDSCH with same-slot scheduling). Thus, the power saving benefits of cross-slot scheduling can be reduced. Furthermore, decoding delays can make it challenging to change hardware configurations (e.g., antennas, beams, etc.) between PDCCH and PDSCH, for example, because such changes require time.

[0135] Therefore, at least in some embodiments, it may be desirable to provide a mechanism for a UE to determine whether a particular interval is same-slot scheduled or cross-slot scheduled before decoding the control information for that interval, or to exclude the possibility of same-slot scheduling in at least some cases. Figure 6 is a flow chart illustrating an example of such a method according to at least some embodiments. Figure 6 Aspects of the method may be implemented by a wireless device such as UE 106 shown in various figures herein, a base station such as BS 102 shown in various figures herein, and / or more generally, may be implemented in conjunction with any of the computer systems or devices shown in the figures above and other devices as desired. For example, any of the various devices may include a device configured to cause the device to perform Figure 6 One or more processors or other processing elements (e.g., 302, 330, 352, 354, 356, 404, 512, 522, etc.) for some or all aspects of the method of FIG.

[0136] In various embodiments, some of the method elements shown may be performed simultaneously in an order different from that shown, may be replaced by other method elements, or may be omitted. Additional elements may also be performed as needed. Note that although the method elements are described in a manner involving the use of communication techniques and / or features associated with 3GPP specification documents, Figure 6 At least some elements of the method, but such description is not intended to limit the present disclosure and can be used in any suitable wireless communication system as needed Figure 6 Furthermore, although the description is made with respect to downlink transmissions Figure 6 However, it should be noted that the method can also be applied to uplink transmission. Figure 6 The method can be operated as follows.

[0137] At 4102, a UE 106 in communication with a base station 102 may receive at least one scheduling parameter transmitted by the base station. The scheduling parameter may be used by the UE to determine the duration of a delay between control information and corresponding data for at least one time period (e.g., a first time slot or a current time slot). For example, the scheduling parameter may indicate whether at least one time slot is cross-slot scheduled or may be same-slot scheduled. For example, in some cases, the scheduling parameter may allow the UE 106 to exclude the possibility of same-slot scheduling for at least one time slot. The scheduling parameter may be applicable to one or more time slots.

[0138] In some embodiments, the at least one scheduling parameter may be transmitted as a (e.g., RRC) configuration, e.g., setting possible K0 values. For example, the at least one scheduling parameter may be an information element (IE) such as PDSCH-TimeDomainResourceAllocationList) that configures a table of possible K0 values. Figure 7 is an illustrative example of such a table. Figure 7 In the example shown, K0 may be in the range of 0 to 32. It should be understood that the table shown is merely exemplary. A table that includes all K0 values greater than 0 (e.g., a table that does not include K0 equal to 0) may indicate that all time slots (e.g., when the RRC configuration is valid) may be cross-slot scheduled. In other words, based on a set of K0 values that are all greater than 0, the UE cannot determine that all time slots are cross-slot scheduled until the RRC configuration is changed. Therefore, the UE can exclude the possibility of scheduling the same time slot while the table is applicable. This approach may be relatively inflexible.

[0139] In some embodiments, the at least one scheduling parameter may be an indication to turn a "frozen K0" feature on or off. Among various possibilities, such an indication may be transmitted, for example, as a Media Access Control (MAC) Control Element (CE) via the PDCCH. Thus, the indication may be used to dynamically adjust K0. During the duration of the active indication to freeze K0, the K0 value may remain constant (e.g., frozen, locked). K0 may be frozen at a specific value (e.g., as specified by the scheduling parameter) or at the current value of K0 (e.g., K0 has not changed from the K0 value that was valid immediately before the scheduling parameter). Based on this indication that K0 is frozen when K0>0, the UE may be able to determine that all time slots are cross-slot scheduled (with a specific delay, as indicated by K0). For example, K0 may be frozen at a first value for a first time period (e.g., time slot a to time slot b, including any number of intervening time slots), may be unfrozen for a second time period (e.g., time slot b+1 to time slot c), and may be frozen at a second value for a third time period (e.g., time slot c+1 to time slot d). This feature may be implemented in at least the following alternative ways.

[0140] In a first alternative, the at least one scheduling parameter may indicate activation / deactivation of K0 freezing. As described above, if K0 is frozen at a current value or indicated value (e.g., based on MAC CE activation freezing), K0 may not be changed until a later MAC CE deactivates freezing.

[0141] In a second alternative, the at least one scheduling parameter may indicate a duration for which K0 may remain constant (e.g., frozen, locked). In other words, the scheduling parameter may indicate a duration for which K0 may remain at a single value, such as a current value or another specified value. Based on this indication, the UE may determine the number of time slots for which K0 may remain at the specified value, for example, the UE may determine the number of time slots for cross-slot scheduling. The scheduling parameter may indicate a start time and an end time for the duration. Alternatively, the scheduling parameter may be relative to the current time, for example, the amount of time for which K0 will not change from its current value. This window may be modified (e.g., extended or possibly shortened) by further indication.

[0142] In a third alternative, the at least one scheduling parameter may indicate a minimum delay time (e.g., a minimum K0 value, K0_min) to be used for a certain period of time (e.g., until changed). For example, the scheduling parameter may set K0_min to be equal to 1, thereby excluding the possibility of same-time slot scheduling, until K0_min is changed to 0.

[0143] It will be appreciated that these alternative approaches may be used in various combinations. For example, the K0_min value may be set for a specified duration. For example, one or more scheduling parameters may indicate that K0 will not be less than 1 for the next 100 time slots, etc. In addition, the K0_min value may be set and frozen or unfrozen (e.g., activated or deactivated) by further indications. For example, K0_min equal to 2 (e.g., or other values as needed) may be set and frozen (e.g., activated) by a first indication. The value of K0 may fluctuate (e.g., as indicated in the DCI), but may be at least 2 after the first indication. A second indication may unfreeze (e.g., deactivate) K0_min, for example, so that K0 may be lower for a certain period of time. In other words, K0 may continue to fluctuate and may reach a value below 2. A third indication may refreeze K0_min, for example, to reactivate the minimum value of 2 (or a different minimum value).

[0144] Furthermore, scheduling parameters indicating one or more future values of K0 and / or K0_min may also be used. For example, a scheduling parameter may be transmitted to indicate that after a window with a first (e.g., frozen) K0 value, a window (future) with a second frozen K0 value may be scheduled. For example, for the next 10 time slots, K0=1, followed by at least one time slot with K0=2 (e.g., or a second window with a second duration), etc. In other words, a schedule of one or more K0 values and / or K0_min values may be set for any number of future windows. Such a schedule may be set (e.g., indicated) by any number of scheduling parameters transmitted at any time or combination of times.

[0145] In some embodiments, at least one scheduling parameter may be a switch indicating whether the delay may be modified for the next time slot. This switch may be implemented in various ways, such as using an index or tag of an element transmitted as DCI. For example, Figure 8 As shown, if the value of the index is the same as in the previous time slot, the switch may indicate that K0 will not be changed for the next time slot (e.g., the downlink (DL) grant in the PDCCH of the next time slot may use the same K0 as the DL grant in the current time slot). In contrast, if the index is different from the previous time slot, the switch may indicate that K0 can or will be changed for the next time slot. To implement the K0 switch, the format of the DCI can be changed, for example, by adding a 1-bit for such a switch indication. According to some embodiments, such a switch in the DCI can be highly flexible, however, it may carry the risk of error propagation. For example, in the absence of a grant (e.g., in the DCI), the UE may miss two PDSCHs in two time slots in a row.

[0146] In some embodiments, BS 102 may dynamically determine whether to apply cross-slot scheduling or same-slot scheduling to UE 106 during one or more time slots. BS 102 may also determine a scheduling parameter or a combination of scheduling parameters to indicate to the UE which type of scheduling applies to the one or more time slots. For example, when BS 102 determines to apply cross-slot scheduling, BS 102 may use any of the various techniques described above to indicate cross-slot scheduling (e.g., indicating to UE 106 that K0 will not be equal to 0 for one or more time slots to which the scheduling parameter applies). BS 102 may transmit the one or more scheduling parameters to UE 106. BS 102 may dynamically (e.g., periodically or as needed, etc.) update the scheduling determination and may transmit additional (e.g., updated) scheduling parameters to the UE based on the updated determination. The one or more scheduling parameters may be transmitted prior to the one or more time slots to which the one or more scheduling parameters apply, e.g., so that the UE can determine whether cross-slot scheduling or same-slot scheduling before receiving control information in the relevant time slots. For example, to allow the UE to realize the benefits of cross-slot scheduling during the first time slot, the BS may transmit scheduling parameters (e.g., indicating cross-slot scheduling for the first time slot) to the UE before the first time slot. During the first time slot, the BS may transmit control information to the UE. The control information may be consistent with one or more scheduling parameters. For example, if the one or more scheduling parameters indicate cross-slot scheduling for the first time slot, the control information transmitted during the first time slot may be applied to data transmissions or other communications (e.g., uplink and / or downlink) scheduled for one or more later time slots (e.g., one or more time slots after the first time slot, e.g., immediately after the first time slot or after one or more intermediate time slots, e.g., consistent with K0). In addition, the BS may perform scheduled transmissions or communications with the UE during the later one or more time slots.

[0147] At 4104, based on at least one scheduling parameter, the UE may determine whether to power down at least some components after receiving the control information during a time slot (e.g., a current time slot). Whether to power down any one or more components may be determined before, after, or during the UE's receipt of the control information. The time slot may be a time slot during which the at least one scheduling parameter is valid.

[0148] In other words, the UE may determine, based on at least one scheduling parameter, that the delay between the control information and the corresponding data is sufficient (or not sufficient) to cause one or more components to shut down or power down, e.g., the corresponding data will not immediately follow the control information. For example, the UE may determine that the scheduling parameter is indicative of cross-slot scheduling for the current time slot. In other words, the UE may determine that the control information for the current time slot is cross-slot scheduling, e.g., that the control information applies to a later time slot, and therefore may determine that data (e.g., PDSCH) will not be transmitted for the UE during the current time slot (e.g., the time slot in which the determination is made). Among various possibilities, the UE may determine that cross-slot scheduling applies based on any of the following: 1) the RRC configuration does not include K0 equal to 0 (e.g., K0 is greater than 0); 2) K0 is frozen at a K0 value greater than 0; 3) K0_min is valid and greater than 0; and / or 4) K0 for the previous time slot is greater than 0, and the switch indicates that K0 will not be changed for the current time slot. Similarly, if none of the previous conditions are true, the UE may determine that same-slot scheduling is possible. If same time slot scheduling is possible, the UE may determine not to power off the component after receiving the control information.

[0149] In some embodiments, the UE may also consider control information from one or more previous time slots to make this determination. For example, the UE may determine whether the control information received in the previous time slot is associated with the current time slot (e.g., cross-slot scheduling). If the control information of the previous time slot includes a downlink grant for the current time slot, the UE may determine not to shut down any components. Therefore, the UE may remain active / awake to receive data (e.g., PDSCH) corresponding to the previously received and decoded control information (e.g., PDCCH).

[0150] In some embodiments, the UE may also determine which specific components to shut down and / or power off. Such components may include any of receive circuitry, RF components, baseband circuitry, antennas, receiver chains, and the like. According to some embodiments, the specific components to be shut down / powered off may be selected based on the length of the delay and / or the amount of time required to shut down and repower the components. For example, in some embodiments, one element (e.g., the RF circuitry or baseband processor) may be powered on / off more quickly than other components of the receiver chain; for example, some elements may have a shorter "off time" or "cycle time" than other elements. Thus, in some cases, there may be an opportunity to save power by temporarily de-energizing one or more elements without de-energizing the rest of the chain (e.g., because the amount of time to de-energize and re-energize the remaining components may exceed the amount of time before these components may be needed). In other words, specific elements may be selected to be shut down based on a comparison of the shutdown time and the transmission time interval (TTI) associated with the active communication session.

[0151] At 4106, based on the determination to power off, the UE may power off at least one component after receiving the control information for the current time interval / time slot and before decoding the control information. Powering off the component may include partially or completely removing power from the component. For example, the component may be shut down or remain operating at a reduced power level (e.g., and potentially with reduced performance / capability).

[0152] Components may remain powered off / off for any length of time. For example, components may remain powered off / off until a period associated with control information in a subsequent time slot. For example, after receiving the PDCCH for the current time slot during the current control information reception period, the UE may power off / off components, and they may remain powered off / off for the remainder of the time slot. For the next control information reception period, for example, within the time to receive the PDCCH for the next time slot, the components may be powered on / off again. The UE may decode control information while the components were powered off / off.

[0153] The control information may be or include DCI transmitted via the PDCCH. The control information may specify any delay (e.g., K0) between the control information and the corresponding data. For example, the control information may indicate a specific time at which the UE receives and / or transmits corresponding downlink and / or uplink data. The UE may power one or more components to receive and / or transmit the corresponding downlink and / or uplink data at the specific time (e.g., in a future time slot specified by the control information).

[0154] In some embodiments, the control information may include additional scheduling parameters, such as one or more of the scheduling parameters discussed above in 4102. Such additional scheduling parameters may be applied to the additional control information received in future time slots. For example, the additional scheduling parameters may be used to determine which one or more time slots may include data corresponding to the future control information. In other words, the one or more additional scheduling parameters may be used to determine whether the future control information may be cross-time slot scheduled, and therefore, whether the component may be powered off in the future time slot.

[0155] In some embodiments, in response to determining that same time slot scheduling as the current time slot is possible, the UE may not power off any components after receiving the control information.
