The disclosure of the prior application is considered a part of this patent application and is incorporated into this patent application by reference. Technical Field

[0004]

[0006] In general, aspects of the disclosure relate to wireless communications and to techniques and apparatus for decoding physical downlink control channels that end at the same symbol or different symbols. Background Art

[0005] 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 released by the Third Generation Partnership Project (3GPP).

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

[0007] 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 the city, country, region, and even global level. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to be better integrated with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0044] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be comprehensive and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings of this article, it should be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be practiced. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions other than or different from 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 embodied by one or more elements of the claims.

[0045] 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 may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0046] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later (including NR technology).

[0047] Figure 1 1 is a diagram showing a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include a plurality of BSs 110 (shown as BSs 110a, BSs 110b, BSs 110c, and BSs 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, 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.

[0048] A BS may provide communication coverage for macro cells, pico cells, femto cells, 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 subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0049] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections using any appropriate transport network, virtual networks, etc.).

[0050] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0051] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0052] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0053] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle-mounted component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0054] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0055] Typically, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0056] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In such cases, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0057] As noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0058] Figure 2 Base station 110 and UE 120 (which may be Figure 1 1. Block diagram of a design 200 of a base station in a base station and a UE in a UE. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0059] 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), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to transmit additional information.

[0060] 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 (DEMOD) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0061] 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.

[0062] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (eg, as described with reference to Figure 6-16 described).

[0063] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide 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. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and a memory 242 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 6-16 described).

[0064] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the base station 110 may perform one or more techniques associated with decoding a physical downlink control channel (PDCCH) that ends at the same symbol, such as a first downlink control information (DCI) and a second DCI, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct e.g. Fig.11 Process 1100, Fig.12 The process 1200 Fig.13 The process of 1300 Fig.15 The process of 1500 Fig.16 1600 and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, interpretation, etc.) by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Fig.11 Process 1100, Fig.12 The process 1200 Fig.13 The process of 1300 Fig.15 The process of 1500 Fig.16The process 1600 and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, interpreting instructions, etc. The scheduler 246 can schedule UEs for data transmission on the downlink and / or uplink.

[0065] In some aspects, the base station 110 may include: a unit for determining that a first distance between an end of a first DCI to be received by a UE and a corresponding first physical downlink shared channel (PDSCH) to be received by the UE satisfies a minimum distance threshold; a unit for determining that a second distance between an end of a second DCI to be received by the UE and a corresponding second PDSCH to be received by the UE satisfies a minimum distance threshold, wherein the end of the first DCI and the end of the second DCI are to be received by the UE at the same symbol; a unit for sending the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the first distance satisfies the minimum distance threshold and the second distance satisfies the minimum distance threshold; and so on.

In some aspects, such a unit may include a combination of Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0068] In some aspects, the UE 120 includes: means for determining that an end of a first DCI and an end of a second DCI are expected to be received at different symbols; means for decoding the first DCI and the second DCI in an order based at least in part on one or more attributes of the first DCI, one or more attributes of the second DCI, or a combination thereof; means for receiving a first PDSCH based at least in part on when the UE 120 decodes the first DCI; and / or means for receiving a second PDSCH based at least in part on when the UE decodes the second DCI.

[0070] As noted above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0071] Figure 3 is a diagram illustrating an example 300 of a time slot format according to various aspects of the present disclosure. Figure 3 As shown, the time-frequency resources in the wireless access network can be divided into resource blocks, shown by a single resource block (RB) 305. RB 305 is sometimes referred to as a physical resource block (PRB). RB 305 includes a set of subcarriers (e.g., 12 subcarriers) and a set of symbols (e.g., 14 symbols) that can be scheduled as a unit by base station 110. In some aspects, RB 305 may include a set of subcarriers in a single time slot. As shown, a single time-frequency resource included in RB 305 may be referred to as a resource element (RE) 310. RE 310 may include a single subcarrier (e.g., in frequency) and a single symbol (e.g., in time). A symbol may be referred to as an orthogonal frequency division multiplexing (OFDM) symbol. RE 310 may be used to send a modulated symbol, which may be a real value or a complex value.

[0072] In some telecommunication systems (e.g., NR), RB 305 may span 12 subcarriers over a duration of 0.1 milliseconds (ms), where the subcarrier spacing is, for example, 15 kilohertz (kHz), 30kHz, 60kHz, or 120kHz, etc. A radio frame may include 40 time slots and may have a length of 10ms. Thus, each time slot may have a length of 0.25ms. However, the time slot length may be changed according to the numerology used for communication (e.g., subcarrier spacing, cyclic prefix format, etc.). The time slot may be configured with a link direction (e.g., downlink or uplink) for transmission. In some aspects, the link direction of the time slot may be dynamically configured. In some communication systems (such as 5G or NR), a UE may send communications to a base station on a physical uplink channel (e.g., physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), etc.) in one or more time slots.

[0073] As noted above, Figure 3 is provided as an example. Other examples may differ from those described above. Figure 3 Examples described.

[0074] Figure 4 4 is a diagram illustrating an example of a downlink (DL)-centric time slot or wireless communication structure in accordance with various aspects of the present disclosure. The DL-centric time slot may include a control portion 402. The control portion 402 may be present at an initial or beginning portion of the DL-centric time slot. The control portion 402 may include various scheduling information and / or control information corresponding to various portions of the DL-centric time slot. In some configurations, the control portion 402 may be a PDCCH, such as Figure 4 In some aspects, the control portion 402 may include legacy PDCCH information, shortened PDCCH (sPDCCH) information, a control format indicator (CFI) value (e.g., carried on a physical control format indicator channel (PCFICH)), one or more grants (e.g., downlink grant, uplink grant, etc.), etc.

[0075] The DL-centric time slot may also include a DL data portion 404. The DL data portion 404 may sometimes be referred to as the payload of the DL-centric time slot. The DL data portion 404 may include communication resources for transmitting DL data from a scheduling entity (e.g., a UE or a BS) to a subordinate entity (e.g., a UE). In some configurations, the DL data portion 404 may be a PDSCH.

[0076] The DL-centric time slot may also include an uplink (UL) short burst portion 406. The UL short burst portion 406 may sometimes be referred to as a UL burst, a UL burst portion, a common UL burst, a short burst, a UL short burst, a common UL short burst, a common UL short burst portion, and / or various other appropriate terms. In some aspects, the UL short burst portion 406 may include one or more reference signals. Additionally or alternatively, the UL short burst portion 406 may include feedback information corresponding to various other portions of the DL-centric time slot. For example, the UL short burst portion 406 may include feedback information corresponding to the control portion 402 and / or the data portion 404. Non-limiting examples of information that may be included in the UL short burst portion 406 include an acknowledgement (ACK) signal (e.g., PUCCH ACK, PUSCH ACK, immediate ACK), a negative acknowledgement (NACK) signal (e.g., PUCCH NACK, PUSCH NACK, immediate NACK), a scheduling request (SR), a buffer status report (BSR), a hybrid automatic repeat request (HARQ) indicator, a channel state indication (CSI), a channel quality indicator (CQI), a sounding reference signal (SRS), a demodulation reference signal (DMRS), PUSCH data, and / or various other suitable types of information. The UL short burst portion 406 may include additional or alternative information, such as information related to a random access channel (RACH) procedure, a scheduling request, and various other suitable types of information.

[0077] like Figure 4 As shown, the end of the DL data portion 404 can be separated in time from the beginning of the UL short burst portion 406. This time separation may sometimes be referred to as a gap, a guard period, a guard interval, and / or various other appropriate terms. This separation provides time for switching from DL communication (e.g., a receive operation performed by a slave entity (e.g., a UE)) to UL communication (e.g., a transmit operation performed by a slave entity (e.g., a UE)). The foregoing is an example of a DL-centric wireless communication structure, and alternative structures with similar features may exist without necessarily departing from the aspects described herein.

[0078] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0079] Figure 5 5 is a diagram 500 illustrating an example of a UL-centric time slot or wireless communication structure in accordance with various aspects of the present disclosure. The UL-centric time slot may include a control portion 502. The control portion 502 may be present at an initial or beginning portion of the UL-centric time slot. Figure 5The control portion 502 in can be similar to the above reference Figure 5 The control portion 502 described above. The UL-centric time slot may also include a UL long burst portion 504. The UL long burst portion 504 may sometimes be referred to as the payload of the UL-centric time slot. The "UL portion" may refer to communication resources used to transmit UL data from a subordinate entity (e.g., a UE) to a scheduling entity (e.g., a UE or a BS). In some configurations, the control portion 502 may be a PDCCH.

[0080] like Figure 5 As shown, the end of the control portion 502 can be separated in time from the beginning of the UL long burst portion 504. This time separation may sometimes be referred to as a gap, a guard period, a guard interval, and / or various other appropriate terms. This separation provides time for switching from DL communication (e.g., a receiving operation performed by a scheduling entity) to UL communication (e.g., a transmission performed by a scheduling entity).

[0081] The UL-centric timeslot may also include a UL short burst portion 506 . Figure 5 The UL short burst portion 506 in the embodiment may be similar to that described above with reference to Figure 4 The UL short burst portion 406 described above may include the combination of Figure 4 Any of the information described herein. The foregoing is one example of a UL-centric wireless communication structure, and alternative structures with similar features may exist without necessarily departing from aspects described herein.

[0082] As noted above, Figure 5 is provided as an example. Other examples may differ from those described above. Figure 5 Examples described.

[0083] Figure 6 An example 600 of PDCCH and PDSCH scheduling in accordance with aspects of the present disclosure is shown.

[0084] The base station may send a PDCCH to schedule resources for a corresponding PDSCH (e.g., PDSCH1). The PDCCH (or PDCCH candidate) may include a DCI (e.g., DCI1). The UE may receive DCI1, wherein the end of DCI1 is received at a symbol (e.g., symbol i). The UE may decode DCI1 to receive PDSCH1, such as Figure 6 As shown. The UE may need a certain amount of time (e.g., number of symbols) to decode DCI1, and therefore PDSCH1 may start at a later symbol (e.g., symbol j). The UE may also receive DCI2, where the end of DCI2 is later than the end of DCI1. The UE may decode DCI2 in order to receive PDSCH2, as shown. Figure 6As shown in Case 1 in . If the end of DCI2 is received after the end of DCI1, the NR scheduling rules implemented at the base station may not allow scheduling of PDSCH2 until after the end of PDSCH1. Therefore, Figure 6 Case 1 in FIG. 1 shows PDSCH2 starting after PDSCH1 ends. Figure 6 As shown in Case 2 and Case 3 in FIG. 1 , the UE may not expect PDSCH2 to start earlier than the end of PDSCH1.

[0085] The UE can decode the DCI in the order in which the DCI arrives. However, if the UE receives the end of DCI1 and the end of DCI2 at the same symbol, e.g. Figure 6 As shown in Cases 4 and 5 in , there may be a problem. Case 4 shows that the UE decodes DCI2 after DCI1, and therefore, PDSCH2 starts after PDSCH1. There is no problem in Case 4. If the UE does not know which DCI to decode first and decodes DCI2 first, as shown in Case 5, the shortened timeline for decoding DCI2 may result in the UE not having time to decode DCI1. There is a question about whether the scheduling for PDSCH2 will conflict with the scheduling for PDSCH1. This may result in data transmission failure (lost PDSCH1), which may waste processing resources and signaling resources of the UE and the base station.

[0086] As noted above, Figure 6 is provided as one or more examples. Other examples may differ from Figure 6 Examples described.

[0087] Figure 7 An example 700 of decoding PDCCHs ending at the same symbol in accordance with various aspects of the present disclosure is shown. Figure 7 A minimum distance 705 between DCI1 and PDSCH1 is shown.

[0088] According to various aspects described herein, a base station may determine whether a first distance between DCI1 and PDSCH1 satisfies a minimum distance threshold, and determine whether a second distance between DCI2 and PDSCH2 satisfies a minimum distance threshold. The base station may determine the minimum distance threshold based at least in part on UE capabilities for decoding DCI, DCI decoding time, DCI size, PDSCH size, number of DCIs to be sent, expected size of the first distance (e.g., symbols), expected size of the second distance, or a combination thereof. If the first distance and the second distance satisfy the minimum distance threshold, such as Figure 7As shown in Case 1 in , the base station can send DCI1 and DCI2. In this way, if DCI1 and DCI2 are received such that the end of DCI1 and the end of DCI2 are received at the same symbol, the UE can decode DCI1 or DCI2 first, and there is no question of which PDSCH is scheduled first. There will be enough time to decode DCI1 and DCI2. If the base station determines that there is not enough time to decode DCI2 and DCI1 in any order, as shown in Case 1 in , the base station can send DCI1 and DCI2 in any order. Figure 7 As shown in case 2 in FIG, if the end of DCI1 and the end of DCI2 end at the same symbol, the base station can avoid sending DCI1 or DCI2. The UE can avoid decoding DCI1 and DCI2 in the order in which there is a PDSCH scheduling conflict or PDSCH loss. Therefore, the UE and the base station avoid wasting processing resources and signaling resources for handling PDSCH conflicts or PDSCH losses.

[0089] As noted above, Figure 7 is provided as one or more examples. Other examples may differ from Figure 7 Examples described.

[0090] Figure 8 is a diagram of an example 800 of decoding PDCCHs, such as DCIs, that end at the same symbol in accordance with various aspects of the present disclosure. Figure 8 BSs 810 (eg, Figure 1 and Figure 2 BS110, etc.) and UE 820 (eg, Figure 1 and Figure 2 UE 120 depicted in FIG. 1 , etc.).

[0091] As shown in reference numeral 830, BS 810 may determine that a first distance between an end of a first DCI to be received by UE 820 and a corresponding first PDSCH satisfies a minimum distance threshold. In some aspects, the first distance, the second distance, and / or the minimum distance may be defined as the distance between an end of a PDCCH (e.g., DCI) and a beginning of a corresponding PDSCH. The distance may be defined in terms of time, number of symbols, etc. Alternatively, in some aspects, the first distance, the second distance, and / or the minimum distance may be defined as the distance between an end of a PDCCH (e.g., DCI) and an end of a corresponding PDSCH.

[0092] As shown in the reference numeral 835, BS 810 may determine that a second distance between an end of a second DCI to be received by UE 820 and a corresponding second PDSCH satisfies a minimum distance threshold. The first DCI and the second DCI may end at the same time or at the same symbol. Although reference is made to a single minimum distance threshold, in some aspects, the minimum distance threshold may include separate distance thresholds for the first distance and the second distance. In some aspects, BS 810 may determine whether the first distance (and similarly the second distance) satisfies the minimum distance threshold by comparing the first distance (e.g., symbol) to the minimum distance threshold.

[0093] As shown in reference numeral 840, BS 810 may send the first DCI and the second DCI based at least in part on the first distance and the second distance satisfying the minimum distance threshold. As shown in reference numeral 845, UE 820 may decode the first DCI and the second DCI to determine a schedule for receiving the first PDSCH and the second PDSCH. As shown in reference numeral 850, BS 810 may send the first PDSCH and the second PDSCH.

[0094] As noted above, Figure 8 is provided as an example. Other examples may differ from those described above. Figure 8 Examples described.

[0095] Fig. 9 An example 900 of decoding PDCCHs ending at the same symbol in accordance with various aspects of the present disclosure is shown. Fig. 9 A first PDCCH (eg, DCI1) is shown ending at the same symbol as a second PDCCH (eg, DCI2). DCI1 is decoded for PDSCH1, and DCI2 is decoded for PDSCH2.

[0096] In some aspects, if DCI1 and DCI2 end at the same symbol, the UE may determine the order in which to decode DCI1 and DCI2 based at least in part on one or more attributes of DCI1, one or more attributes of DCI2, or a combination thereof. This may include determining which PDSCH arrives first. For example, the order in which the first DCI and the second DCI are decoded may be based at least in part on the order of the starting symbol of the first DCI and the starting symbol of the second DCI. A smaller starting symbol index of a PDCCH candidate may correspond to a smaller PDCCH candidate ranking index. "PDCCH candidate ranking index" may refer to the order of a PDCCH candidate (e.g., a potential DCI transmission from a gNB) relative to other PDCCH candidates for decoding by the UE.

[0097] like Fig. 9As shown, DCI1 starts at the symbol with index a, and DCI2 starts at the symbol with index b. Because index a comes before index b, even if DCI1 and DCI2 end at the same symbol, the UE can decode DCI1 first, and PDSCH1 can be scheduled before PDSCH2. In a similar scenario, if DCI2 starts before DCI1, the UE can decode DCI2 first, and PDSCH2 can be scheduled before PDSCH1. Without this specified order, the UE may decode DCI2 before DCI1, which may be a problem if PDSCH1 is scheduled before PDSCH2. By Fig. 9 The unsorted example at the bottom of shows this.

[0098] In some aspects, the order in which the first DCI and the second DCI are decoded may be based at least in part on the order of a control resource set (CORESET) identifier for the first DCI and a CORESET identifier (ID) for the second DCI. A CORESET may define a frequency resource block and an OFDM symbol duration for a control region for PDCCH monitoring. A smaller CORESET ID may correspond to a smaller PDCCH candidate ranking index.

[0099] In some aspects, the order in which the first DCI and the second DCI are decoded can be based at least in part on the order of the search space set identifier for the first DCI and the search space set identifier for the second DCI. The search space set defines the time domain starting symbol of the control region for PDCCH monitoring. A smaller search space set ID can correspond to a smaller PDCCH candidate ranking index.

[0100] In some aspects, the order in which the first DCI and the second DCI are decoded may be based at least in part on an aggregation level for the first DCI and an aggregation level for the second DCI. The aggregation level may correspond to the number of control channel elements assigned to the PDCCH candidate. A smaller aggregation level may correspond to a smaller PDCCH candidate ranking index.

[0101] In some aspects, the order in which the first DCI and the second DCI are decoded may be based at least in part on the order of the PDCCH candidate index of the first DCI and the PDCCH candidate index of the second DCI.A smaller PDCCH candidate index may correspond to a smaller PDCCH candidate ranking index.

[0102] The UE may determine the order in which to decode the DCI based at least in part on the order of arrival of the PDSCH. In some aspects, receiving the first PDSCH and receiving the second PDSCH may include receiving the first PDSCH and the second PDSCH in an order based at least in part on the order of the start symbol index of the first PDSCH and the start symbol index of the second PDSCH. Alternatively, in some aspects, receiving the first PDSCH and receiving the second PDSCH may include receiving the first PDSCH and the second PDSCH in an order based at least in part on the order of the end symbol index of the first PDSCH and the end symbol index of the second PDSCH.

[0103] The base station may use a candidate ranking index for the PDSCH to indicate the order of the PDSCH. The candidate ranking index of the PDSCH may indicate to the UE that it is associated with a candidate ranking index (e.g., DCI) of a PDCCH candidate. For example, the order in which the first DCI and the second DCI are decoded may be based at least in part on the order of the candidate ranking index of the first PDSCH and the candidate ranking index of the second PDSCH. In other words, if the UE decodes the DCI from a lower ranking index to a higher ranking index, the UE may first decode the DCI for the PDSCH with a smaller ranking index.

[0104] As noted above, Fig. 9 is provided as one or more examples. Other examples may differ from Fig. 9 Examples described.

[0105] Fig.10 is a diagram illustrating an example 1000 of decoding PDCCHs ending at the same symbol in accordance with various aspects of the present disclosure. Fig.10 BSs 1010 (eg, Figure 1 and 2 BS110 depicted in Figure 8 BS 810, etc.) and UE 1020 (e.g., Figure 1 and 2 UE 120 depicted in Figure 8 UE 820 depicted in FIG. 8 , etc.).

[0106] As shown at reference numeral 1030, UE 1020 may receive a first DCI and a second DCI from BS 1010. As shown at reference numeral 1035, UE 1020 may determine that the first DCI and the second DCI end at the same symbol. As shown at reference numeral 1040, UE 1020 may decode the first DCI and the second DCI in an order based at least in part on one or more attributes of the first DCI, one or more attributes of the second DCI, or a combination thereof. For example, as shown in combination with Fig. 9 As described, the UE 1020 may compare the attributes of the first DCI or the first PDSCH (e.g., candidate ranking index, CORESET ID, search space set ID, aggregation level, etc.) with the attributes of the second DCI or PDSCH. The UE may determine the order in which to decode the first DCI and the second DCI based at least in part on the result of the comparison.

[0107] As indicated by reference numeral 1045, the UE 1020 may receive the first PDSCH and the second PDSCH in an order based at least in part on the order in which the UE 1020 decoded the first DCI and the second DCI. The BS 1010 and the UE 1020 may operate at least in part based on the same ordering rule so that the BS 1010 knows when the UE 1020 is to receive a specific DCI or a specific PDSCH. Due to the intentional ordering for decoding the DCI, the BS 1010 and the UE 1020 avoid wasting processing resources and signaling resources due to handling conflicting PDSCHs or lost PDSCHs.

[0141] Although Fig.12 An example block diagram of process 1200 is shown, but in some aspects, process 1200 may include Fig.12 The blocks depicted in the process 1200 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1200. Additionally or alternatively, two or more blocks in the blocks of process 1200 may be executed in parallel.

[0142] Fig.13 1 is a diagram illustrating an example process 1300 performed, for example, by a base station, according to various aspects of the present disclosure. Example process 1300 is a diagram in which a base station (e.g., Figure 1 and 2 BS110 depicted in Figure 8 BS 810, as depicted in Fig.10 An example of BS1010, etc. depicted in performing operations associated with decoding PDCCHs that end at the same symbol.

[0143] like Fig.13As shown, in some aspects, process 1300 may include determining that the UE is to receive an end of the first DCI and an end of the second DCI at the same symbol (block 1310).

[0151] In a fourth aspect, alone or in combination with one or more of the first to third aspects, an order in which the first DCI and the second DCI are decoded is based at least in part on an aggregation level for the first DCI and an aggregation level for the second DCI.

[0152] In the fifth aspect, alone or in combination with one or more of the first to fourth aspects, the order in which the first DCI and the second DCI are decoded is at least partially based on the order of the candidate indexes of the first DCI and the candidate indexes of the second DCI.

[0153] In the sixth aspect, alone or in combination with one or more aspects of the first to fifth aspects, sending the first PDSCH and sending the second PDSCH include: sending the first PDSCH and the second PDSCH in an order based at least in part on the order of the starting symbol index of the first PDSCH and the starting symbol index of the second PDSCH.

[0155] In the eighth aspect, alone or in combination with one or more of the first to seventh aspects, the order in which the first DCI and the second DCI are decoded is at least partially based on the order of the candidate sorting index of the first PDSCH and the candidate sorting index of the second PDSCH.

[0156] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the process 1300 includes: scheduling the first PDSCH and the second PDSCH only via unicast scheduling.

[0157] In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, the process 1300 includes: scheduling the first PDSCH and the second PDSCH via unicast scheduling or broadcast scheduling.

[0158] In the eleventh aspect, alone or in combination with one or more aspects of the first to tenth aspects, sending the first DCI, the first PDSCH, the second DCI and the second PDSCH includes: sending the first DCI, the first PDSCH, the second DCI and the second PDSCH at least partially based on the type of UE.

[0160] Although Fig.13 Example blocks of process 1300 are shown, but in some aspects, process 1300 may include Fig.13 The blocks depicted in the process 1300 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1300. Additionally or alternatively, two or more blocks in the blocks of process 1300 may be executed in parallel.

[0161] Fig.14 1400 , 1402 illustrate examples of decoding PDCCH ending at different symbols in accordance with various aspects of the present disclosure.

[0162] In some aspects, the base station may determine that the UE is to receive the end of the first DCI and the end of the second DCI at different symbols, and determine that the UE is to decode the first DCI and the second DCI in an order based at least in part on one or more attributes of the first DCI, one or more attributes of the second DCI, or a combination thereof. The base station may send the first PDSCH based at least in part on when the UE is to decode the first DCI, and may send the second PDSCH based at least in part on when the UE is to decode the second DCI. The UE may expect to receive the first DCI and the second DCI at different symbols instead of the same symbol. That is, the UE may be configured, scheduled and / or signaled to receive the end of the DCI at different symbols, but not configured, scheduled or signaled to receive the end of the DCI at the same symbol. The UE may not monitor the end of the DCI to be received at the same symbol. In some aspects, if the end of the DCI happens to be received at the same symbol, the UE may not be prepared to receive two PDSCHs. For example, for any two HARQ process IDs in a given scheduled cell, if the UE is scheduled to receive a first PDSCH starting in symbol j via a PDCCH ending in symbol i, the UE is not expected to be scheduled to receive a second PDSCH scheduled by a second PDCCH ending in symbol i.

[0163] Example 1400 shows a first DCI (DCI1) having an end received at an earlier symbol than a symbol for an end of a second DCI (DCI2). The base station sends the first PDSCH (PDSCH1) before the second PDSCH (PDSCH2). Example 1402 shows that DCI2 ends before DCI1, and the base station sends PDSCH2 before PDSCH1.

[0164] As noted above, Fig.14 Some examples are provided. Other examples may differ from those regarding Fig.14 Examples described.

[0193] As used herein, satisfying a threshold may refer to a value being greater than a threshold, greater than or equal to a threshold, less than a threshold, less than or equal to a threshold, equal to a threshold, not equal to a threshold, etc., depending on the context.

[0194] It will be apparent that the systems and / or methods described herein can be implemented with various forms of hardware, software, and / or combinations of hardware and software. The actual specialized control hardware or software code used to implement these systems and / or methods is not limiting in any respect. Therefore, the operation and behavior of the systems and / or methods are described herein without reference to specific software code, it being understood that software and hardware can be designed to implement the systems and / or methods based, at least in part, on the description herein.

[0195] Even if a specific combination of features is recorded in the claims and / or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. In fact, many of these features can be combined in a manner that is not specifically recorded in the claims and / or specifically disclosed in the specification. Although each dependent claim listed below can only be directly subordinate to a claim, the disclosure of various aspects includes the combination of each dependent claim with each other claim in the claim set. The phrase "at least one of" referring to the list of items refers to any combination of those items, including a single member. For example, "at least one of a, b or c" is intended to cover any combination of a, b, c, ab, ac, bc and abc, and with multiples of the same element (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc and ccc or any other ordering of a, b and c).

[0196] Elements, actions or instructions used herein should not be interpreted as key or necessary, unless explicitly described as such. In addition, as used herein, the articles "a" and "an" are intended to include one or more projects, and can be used interchangeably with "one or more". In addition, as used herein, the terms "set" and "group" are intended to include one or more projects (e.g., related projects, unrelated projects, combinations of related projects and unrelated projects, etc.), and can be used interchangeably with "one or more". In the case of only expecting one project, the phrase "only one" or similar language is used. In addition, as used herein, the terms "has", "have", "having" etc. are intended to be open terms. In addition, unless otherwise explicitly stated, the phrase "based on" is intended to mean "based at least in part on".
