Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of and priority to U.S. Provisional Patent Application Serial No. 62 / 903,536, filed on September 20, 2019, which is incorporated herein by reference in its entirety as if fully set forth below and for all applicable purposes. Technical Field

[0003] Aspects of the present disclosure relate to wireless communications and, more particularly, to techniques for adjusting scheduling offsets for wireless communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, Advanced LTE (LTE-A) systems, 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, to name a few.

[0005] In some examples, a wireless multiple access communication system may include multiple base stations (BS), each of which is capable of simultaneously supporting communications for multiple communication devices (also referred to as user equipment (UE)). In an LTE or LTE-A network, a set of one or more base stations may define an evolved Node B (eNB). In other examples (e.g., in a next generation, new radio (NR) or 5G network), a wireless multiple access communication system may include multiple distributed units (DU) (e.g., edge units (EU), edge nodes (EN), radio heads (RH), smart radio heads (SRH), transmit receive points (TRP), etc.) communicating with multiple central units (CU) (e.g., central nodes (CN), access node controllers (ANC), etc.), wherein a set of one or more distributed units communicating with a central unit may define an access node (e.g., which may be referred to as a base station, 5GNB, next generation Node B (gNB or gNodeB), TRP, etc.). A base station or distributed unit may communicate with a set of UEs on downlink channels (eg, for transmissions from the base station or to the UE) and uplink channels (eg, for transmissions from the UE to the base station or distributed unit).

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. New Radio (NR) (e.g., 5G) is an example of an emerging telecommunication standard. NR is an enhancement set to the LTE mobile standard released by 3GPP. It is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using OFDMA with cyclic prefix (CP) on the downlink (DL) and on the uplink (UL), thereby better supporting mobile broadband Internet access. To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0007] However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ them. Summary of the invention

[0037] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for adjusting scheduling offsets for wireless communications.

[0038] The following description provides examples, rather than limiting the scope, applicability, or examples set forth in the claims. Changes may be made in the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various processes or components may be omitted, replaced, or added to each example as appropriate. For example, the method described may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, the features described with respect to some examples may be combined in some other examples. For example, a device may be implemented or a method may be implemented using any number of aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims. The word "exemplary" is used herein to mean "used as an example, instance, or illustration". Any aspect described as "exemplary" herein may not necessarily be interpreted as preferred or having advantages over other aspects.

[0039] The technology described herein can be used for various wireless communication technologies, such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), CDMA2000, etc. UTRA includes other variants of Wideband CDMA (WCDMA) and CDMA. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network can implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS).

[0040] New Radio (NR) is an emerging wireless communication technology under development in conjunction with the 5G Technology Forum (5GTF). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The technology described herein can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, 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 technologies (including NR technologies).

[0041] New Radio (NR) access (e.g., 5G technology) can support various wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80 MHz or above), millimeter wave (mmW) targeting high carrier frequency (e.g., 25 GHz or above), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet corresponding quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.

[0042] Example Wireless Communication System

[0043] Figure 1 An example wireless communication network 100 is shown in which aspects of the present disclosure, including adjusting a scheduling offset for wireless communications, may be performed. For example, the wireless communication network 100 may be a New Radio (NR) or 5G network.

[0044] For example, Figure 1 As shown in, UE 120a has a carrier group (CG) scheduling manager 122, which can be configured to: receive a time domain configuration, the time domain configuration includes one or more offset values ​​of time domain resources relative to the reception of a physical downlink control channel (PDCCH), each of the one or more offset values ​​indicates a scheduling offset, the scheduling offset indicates the number of time slots offset from the reception of the PDCCH, the UE is configured with a scheduling adaptation configuration, the scheduling adaptation configuration includes one or more minimum offset values ​​relative to the reception of the PDCCH, the one or more minimum offset values ​​correspond to a carrier group, each of the one or more minimum offset values ​​corresponds to one or more carriers in the carrier group and indicates a minimum scheduling offset, the minimum scheduling offset indicates the minimum number of time slots offset from the reception of the PDCCH.

[0045] The CG scheduling manager 122 may also be configured to: for each carrier in the carrier group, determine that at least one of the one or more offset values ​​is greater than or equal to the minimum offset value of the corresponding carrier. The CG scheduling manager 122 may also be configured to: for each carrier in the carrier group, perform one or more of the following operations: utilize time domain resources to transmit on a physical uplink shared channel (PUSCH) or monitor a physical downlink shared channel (PDSCH), and the time domain resources correspond to at least one of the one or more offset values ​​that are greater than or equal to the minimum offset value of the corresponding carrier.

[0046] In another example, if Figure 1 As shown in the figure, BS110a has a CG scheduling manager 124, which can be configured to: send a time domain configuration to a user equipment (UE), the time domain configuration including one or more offset values ​​of time domain resources relative to the reception of a physical downlink control channel (PDCCH) by the UE, each of the one or more offset values ​​indicating a scheduling offset, the scheduling offset indicating the number of time slots offset from the reception of the PDCCH by the UE.

[0047] The CG scheduling manager 124 can also be configured to: send a scheduling adaptation configuration to the UE, the scheduling adaptation configuration including one or more minimum offset values ​​relative to the reception of the PDCCH, the one or more minimum offset values ​​corresponding to a carrier group, each of the one or more minimum offset values ​​corresponding to one or more carriers in the carrier group and indicating a minimum scheduling offset, the minimum scheduling offset indicating a minimum number of time slots offset from the reception of the PDCCH.

[0048] The CG scheduling manager 124 can also be configured to: for each carrier in the carrier group, perform one or more of the following operations: utilize time domain resources to transmit on a physical downlink shared channel (PDSCH) or receive on a physical uplink shared channel (PUSCH), and the time domain resources correspond to at least one of one or more offset values ​​that are greater than or equal to the minimum offset value of the corresponding carrier.

[0049] like Figure 1 As shown in , the wireless network 100 may include multiple base stations (BS) 110 and other network entities. A BS may be a station that communicates with a user equipment (UE). Each BS 110 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a node B (NB) and / or a node B subsystem serving the coverage area, depending on the context in which the term is used. In the NR system, the term "cell" and the next generation node B (gNB), new radio base station (NR BS), 5G NB, access point (AP), or transmit receive point (TRP) may be interchangeable. In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move according to the location of the mobile BS. In some examples, the base station may be interconnected to each other and / or to one or more other base stations or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (such as direct physical connections, wireless connections, virtual networks, or interfaces using any appropriate transport networks).

[0050] Generally, 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, subcarrier, frequency channel, tone, subband, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks with different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0051] A base station (BS) may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. 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), UEs for users in a residence, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG. 1 , BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.

[0052] The wireless communication network 100 may also include a relay station. A relay station is a station that receives data transmissions and / or other information from an upstream station (e.g., a BS or a UE) and sends data transmissions and / or other information to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown in , a relay station 110r may communicate with a BS 110a and a UE 120r to facilitate communication between the BS 110a and the UE 120r. A relay station may also be referred to as a relay BS, a relay, or the like.

[0053] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relays, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 20 watts), while a pico BS, a femto BS, and a relay may have a lower transmit power level (e.g., 1 watt).

[0054] The wireless communication network 100 may support synchronous operation or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.

[0055] A network controller 130 may couple to a set of BSs and provide coordination and control for these BSs. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0056] UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as mobile stations, terminals, access terminals, subscriber units, stations, customer premises equipment (CPE), cellular phones, smart phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet computers, cameras, gaming devices, netbooks, smartbooks, ultrabooks, appliances, medical devices or medical apparatuses, biometric sensors / devices, wearable devices (such as smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets, etc.)), entertainment devices (e.g., music devices, video devices, satellite radio units, etc.), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, or any other suitable device configured to communicate via a wireless or wired medium. Some UEs may be considered as machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0057] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, frequency bins, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are sent in the frequency domain using OFDM and in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing of the subcarriers can be 15kHz and the minimum resource allocation (referred to as a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be partitioned into subbands. For example, a subband may cover 1.8 MHz (ie, 6 resource blocks), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively.

[0058] Although aspects of the examples described herein may be associated with LTE technology, aspects of the present disclosure may be applied with other wireless communication systems such as NR. NR may utilize OFDM with CP on the uplink and downlink and include support for half-duplex operation using TDD. Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmissions with precoding may also be supported. MIMO configurations in the DL may support up to 8 transmit antennas with multi-layer DL transmissions of up to 8 streams and up to 2 streams per UE. Multi-layer transmissions with up to 2 streams per UE may be supported. Aggregation of multiple cells with up to 8 serving cells may be supported.

[0059] In some examples, access to the air interface can be scheduled. The scheduling entity (e.g., base station) allocates resources for communication between some or all devices and apparatuses in its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, the subordinate entity utilizes the resources allocated by the scheduling entity. The base station is not the only entity that can be used as a scheduling entity. In some examples, the UE may be used as a scheduling entity, and resources for one or more subordinate entities (e.g., one or more other UEs) may be scheduled, and other UEs may utilize the resources scheduled by the UE for wireless communication. In some examples, the UE may be used as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, the UEs may also communicate directly with each other.

[0060] exist Figure 1 In FIG. 1 , a solid line with double arrows indicates desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE on the downlink and / or uplink. A thin dashed line with double arrows indicates interfering transmissions between a UE and a BS.

[0061] Figure 2 As shown (as in Figure 1 1 and 120, which may be used to implement aspects of the present disclosure. For example, antenna 252, processors 266, 258, 264, and / or controller / processor 280 of UE 120, and / or antenna 234, processors 220, 260, 238, and / or controller / processor 240 of BS 110 may be used to perform the various techniques and methods described herein.

[0062] like Figure 2 As shown in, UE 120a has a processor 280 including a CG scheduling manager 122, which can be configured to: receive a time domain configuration, the time domain configuration including one or more offset values ​​of time domain resources relative to the reception of a physical downlink control channel (PDCCH), each of the one or more offset values ​​indicating a scheduling offset, the scheduling offset indicating the number of time slots offset from the reception of the PDCCH, the UE is configured with a scheduling adaptation configuration, the scheduling adaptation configuration including one or more minimum offset values ​​relative to the reception of the PDCCH, the one or more minimum offset values ​​corresponding to a carrier group, each of the one or more minimum offset values ​​corresponding to one or more carriers in the carrier group and indicating a minimum scheduling offset, the minimum scheduling offset indicating the minimum number of time slots offset from the reception of the PDCCH.

[0063] The CG scheduling manager 122 may also be configured to: for each carrier in the carrier group, determine that at least one of the one or more offset values ​​is greater than or equal to the minimum offset value of the corresponding carrier. The CG scheduling manager 122 may also be configured to: for each carrier in the carrier group, perform one or more of the following operations: utilize time domain resources to transmit on a physical uplink shared channel (PUSCH) or monitor a physical downlink shared channel (PDSCH), and the time domain resources correspond to at least one of the one or more offset values ​​that are greater than or equal to the minimum offset value of the corresponding carrier.

[0064] like Figure 2 As shown in, BS110a has a processor 240 including a CG scheduling manager 124, which can be configured to: send a time domain configuration to a user equipment (UE), the time domain configuration including one or more offset values ​​of time domain resources relative to the reception of a physical downlink control channel (PDCCH) by the UE, each of the one or more offset values ​​indicating a scheduling offset, the scheduling offset indicating the number of time slots offset from the reception of the PDCCH by the UE.

[0065] In some examples, the CG scheduling manager 124 can be configured to: send a scheduling adaptation configuration to the UE, the scheduling adaptation configuration including one or more minimum offset values ​​relative to the reception of the PDCCH, the one or more minimum offset values ​​corresponding to a carrier group, each of the one or more minimum offset values ​​corresponding to one or more carriers in the carrier group and indicating a minimum scheduling offset, the minimum scheduling offset indicating a minimum number of time slots offset from the reception of the PDCCH.

[0066] In some examples, the CG scheduling manager 124 can be configured to: for each carrier in the carrier group, perform one or more of the following operations: utilize time domain resources to transmit on a physical downlink shared channel (PDSCH) or receive on a physical uplink shared channel (PUSCH), and the time domain resources correspond to at least one of one or more offset values ​​that are greater than or equal to the minimum offset value of the corresponding carrier.

[0067] At BS110, a transmit processor 220 may receive data from a data source 212 and control information from a controller / processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. The processor 220 may process (e.g., encode and symbol map) the data and the control information, respectively, to obtain data symbols and control symbols. The processor 220 may also generate reference symbols, such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a cell-specific reference signal (CRS). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a through 232t may be transmitted via antennas 234a through 234t, respectively.

[0068] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and may provide received signals to demodulators (DEMODs) 254a to 254r in the transceiver, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information to the controller / processor 280.

[0069] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 280 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by demodulators 254a to 254r in the transceiver (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the BS 110, the uplink signal from the UE 120 may be received by the antenna 234, processed by the modulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240 .

[0070] Controllers / processors 240 and 280 may direct the operation at base station 110 and UE 120, respectively. Processor 240 and / or other processors and modules at base station 110 may perform or direct the execution of processes for the techniques described herein. Memories 242 and 282 may store data and program codes for BS 110 and UE 120, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0071] The controller / processor 280 and / or other processors and modules at the UE 120a may perform or direct the execution of processes for the techniques described herein. Figure 2 As shown in , the controller / processor 280 of UE 120a includes a CG scheduling manager 122. The CG scheduling manager 122 can be configured to: receive a time domain configuration, the time domain configuration includes one or more offset values ​​of time domain resources relative to the reception of a physical downlink control channel (PDCCH), each of the one or more offset values ​​indicates a scheduling offset, the scheduling offset indicates the number of time slots offset from the reception of the PDCCH, the UE is configured with a scheduling adaptation configuration, the scheduling adaptation configuration includes one or more minimum offset values ​​relative to the reception of the PDCCH, each of the one or more minimum offset values ​​corresponds to one or more carriers in a carrier group and indicates a minimum scheduling offset, the minimum scheduling offset indicates the minimum number of time slots offset from the reception of the PDCCH.

[0072] In certain aspects, the CG scheduling manager 122 may be configured to determine, for each carrier in the carrier group, that at least one of the one or more offset values ​​is greater than or equal to a minimum offset value for the corresponding carrier. According to aspects of the present disclosure, the CG scheduling manager 122 may also monitor, for each carrier in the carrier group, a physical downlink shared channel (PDSCH) at a time domain resource corresponding to at least one of the one or more offset values ​​that is greater than or equal to a minimum offset value for the corresponding carrier. Although shown at the controller / processor, other components of the UE 120a and BS 110a may be used to perform the operations described herein.

[0073] In LTE, the basic transmission time interval (TTI) or packet duration is a 1ms subframe. In NR, the subframe is still 1ms, but the basic TTI is called a time slot. A subframe contains a variable number of time slots (e.g., 1, 2, 4, 8, 16... time slots), depending on the subcarrier spacing. NR RBs are 12 consecutive frequency subcarriers. NR can support a basic subcarrier spacing of 15KHz, and other subcarrier spacings can be defined relative to the basic subcarrier spacing, such as 30kHz, 60kHz, 120kHz, 240kHz, etc. The symbol and time slot lengths scale with the subcarrier spacing. The CP length also depends on the subcarrier spacing.

[0074] Figure 3 300 for NR. The transmission timeline for each of the downlink and uplink may be divided into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be divided into 10 subframes with indices 0 to 9, each subframe being 1 ms. Each subframe may include a variable number of slots, depending on the subcarrier spacing. Each slot may include a variable number of symbol periods (e.g., 7 or 14 symbols), depending on the subcarrier spacing. An index may be assigned to the symbol period in each slot. A microslot (which may be referred to as a subslot structure) refers to a transmission time interval (e.g., 2, 3, or 4 symbols) having a duration less than a slot.

[0075] Each symbol in a slot may indicate a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction of each subframe may be dynamically switched. The link direction may be based on the slot format. Each slot may include DL / UL data and DL / UL control information.

[0076] In NR, a synchronization signal (SS) block is transmitted. The SS block includes PSS, SSS, and two-symbol PBCH. It can be sent at a fixed time slot position (such as Figure 3SS blocks are sent in the physical downlink shared channel (symbols 0-3 shown in ). PSS and SSS can be used by UE for cell search and acquisition. PSS can provide half-frame timing, and SS can provide CP length and frame timing. PSS and SSS can provide cell identity. PBCH carries certain basic system information, such as downlink system bandwidth, timing information within a radio frame, SS burst set period, system frame number, etc. SS blocks can be organized into SS bursts to support beam scanning. Additional system information, such as remaining minimum system information (RMSI), system information block (SIB), other system information (OSI), can be sent on the physical downlink shared channel (PDSCH) in certain subframes.

[0077] The UE may operate in various radio resource configurations, including configurations associated with sending pilots using a dedicated set of resources (e.g., a radio resource control (RRC) dedicated state, etc.), or configurations associated with sending pilots using a common set of resources (e.g., an RRC common state, etc.). When operating in the RRC dedicated state, the UE may select a dedicated set of resources for sending pilot signals to the network. When operating in the RRC common state, the UE may select a common set of resources for sending pilot signals to the network. In either case, the pilot signal sent by the UE may be received by one or more network access devices (such as an access node (AN) or a DU or a portion thereof). Each receiving network access device may be configured to receive and measure the pilot signal sent on the common set of resources, and also receive and measure the pilot signal sent on the dedicated set of resources allocated to the UE (for which the network access device is a member of a set of network access devices that monitor the UE). A CU that receives measurement results of one or more of the network access devices, or to which a network access device sends a pilot signal, may use the measurement results to identify a serving cell for a UE, or initiate a change to a serving cell for one or more of the UEs.

[0078] Example Adjustment of Scheduling Offset for Wireless Communications

[0079] You can schedule Figure 1 For example, a BS (e.g., Figure 1 BS 110) can send a signal to a UE (eg, Figure 1In some aspects, BS 110 sends scheduling information to UE 120 in a physical downlink control channel (PDCCH). In one example, BS 110 sends DL allocation indicating parameters for UE 120 to receive data from BS 110 on PDSCH. In another example, BS 110 sends UL grant indicating parameters for UE 120 to send data to BS 110 on PUSCH.

[0080] In certain aspects, UE 120 is configured with one or more time domain resource allocation tables, such as in accordance with 3GPP specification 38.214 version 15.2.0 (eg, sections 5.1.2.1 and 6.1.2.1). Figure 4 An example time-domain resource allocation table 400 for PDSCH is depicted. It should be noted that the UE 120 may be configured with a similar time-domain resource allocation table for PUSCH, may be configured with a single time-domain resource allocation table for both PDSCH and PUSCH, and so on.

[0081] As shown, the time domain resource allocation table 400 includes columns corresponding to row indices and scheduling parameters, including a scheduling offset (e.g., k0 for PDSCH or k2 for PUSCH), a starting symbol index (S), and a number of symbols (L). Each row of the table 400 corresponds to an entry of the table 400. In certain aspects, the table 400 includes up to 16 rows. In addition, each row is indexed by its row index value.

[0082] In certain aspects, the scheduling information sent by BS 110 in the PDCCH to UE 120 includes a row index value. UE 120 is also configured to select a row of table 400 using the row index value, and use the scheduling parameters in the selected row to determine the time domain resources to be used for communication with BS 110 (such as on the PDSCH and / or PUSCH corresponding to the PDCCH).

[0083] The scheduling offset indicates the number of time slots offset from the reception of the PDCCH including the scheduling information by the UE 120. The UE 120 is configured to determine the time slot for communicating with the BS 110 (e.g., for receiving the PDSCH or transmitting the PUSCH) relative to the time slot in which the PDCCH is received using the scheduling offset. For example, if the UE 120 receives a PDCCH indicating a row index and a DL allocation corresponding to the PDSCH for the UE 120 in time slot n, and the scheduling offset associated with the row index is k0, the UE 120 determines that the PDSCH is transmitted by the BS 110 in time slot n+k0, and monitors the PDSCH in time slot n+k0. In another example, if the UE 120 receives a PDCCH indicating a row index and a UL grant corresponding to the PUSCH for the UE 120 in time slot n, and the scheduling offset associated with the row index is k2, the UE 120 determines to transmit the PUSCH to the BS 110 in time slot n+k2.

[0084] The starting symbol index indicates the starting symbol within the time slot indicated by the scheduling offset. The UE 120 is configured to use the starting symbol to determine the first symbol to be used for communicating with the BS 110 (e.g., for receiving the PDSCH or transmitting the PUSCH) in the time slot determined based on the scheduling offset. For example, if the starting symbol index associated with the row index from the PDCCH is S, the UE 120 determines that the BS 110 transmits the PDSCH starting from symbol S in the time slot n+k0, and monitors the PDSCH starting from symbol S in the time slot n+k0. In another example, if the starting symbol index associated with the row index from the PDCCH is S, the UE 120 determines that the PUSCH is transmitted starting from symbol S in the time slot n+k2.

[0085] The number of symbols indicates the number of symbols starting from the symbol indicated by the starting symbol index. The UE 120 is configured to use the number of symbols to determine the symbols (including the number of symbols) to be used for communicating with the BS 110 (e.g., for receiving the PDSCH or sending the PUSCH) starting from the first symbol determined based on the starting symbol index. For example, if the number of symbols associated with the row index from the PDCCH is L, the UE 120 determines that the BS 110 sends the PDSCH on symbols S, S+1, ...S+(L-1) in the time slot n+k0, and monitors the PDSCH on symbols S, S+1, ...S+(L-1) in the time slot n+k0. In another example, if the number of symbols associated with the row index from the PDCCH is L, the UE 120 determines that the PUSCH is sent on symbols S, S+1, ...S+(L-1) in the time slot n+k2.

[0086] In certain aspects, in the same time slot scheduling, the starting symbol index may be limited to symbols in the time slot that include or follow symbols for a control channel (e.g., PDCCH). Figure 5A An example of same slot scheduling is shown. In some examples, in cross-slot scheduling, the starting symbol index can be located in any part of the slot after the slot carrying the PDCCH indicating the starting symbol index. Figure 6 An example of cross-slot scheduling is shown.

[0087] In some aspects, the UE 120 is initially configured (e.g., at the time of manufacture, via an update (e.g., an over-the-air (OTA) update), etc.) with one or more default time domain resource allocation tables. For example, table 400 may correspond to a default time domain resource allocation table for PDSCH allocation. In some aspects, the one or more default time domain resource allocation tables are the same for all UEs 120 in the wireless network 100. Further, in some aspects, the BS 110 configures the UE 120 with one or more UE-specific time domain resource allocation tables (e.g., overriding the default time domain resource allocation table), such as using RRC signaling. In some cases, such RRC signaling may take 20 ms to 30 ms to complete, which results in a delay in configuring the UE 120. Furthermore, to configure UE 120 with one or more UE-specific time domain resource allocation tables, BS 110 may send the entire UE-specific time domain resource allocation table to UE 120 using RRC signaling that utilizes bandwidth and communication resources.

[0088] Although certain aspects are described with respect to a UE 120 configured with a time domain resource allocation table indicating different scheduling offsets, it should be noted that the UE 120 may be configured in other ways and various aspects of the present invention may still apply. For example, the UE 120 may have some other type of time domain resource allocation configuration that includes one or more different configurations that each indicate a scheduling offset.

[0089] In certain aspects, the PDSCH is sent by the BS 110 in the same time slot as the PDCCH that schedules the PDSCH. For example, it may be desirable to schedule system information (e.g., remaining minimum system information (RMSI)) to be transmitted on the PDSCH in the same time slot as the corresponding PDCCH. In such a case, the PDCCH may indicate a scheduling offset of 0 to the UE 120 to indicate that the PDSCH is scheduled in the same time slot as the PDCCH.

[0090] In certain aspects, communications are scheduled across time slots (eg, on PUSCH or PDSCH). In such cases, the PDCCH may indicate a scheduling offset greater than zero to the UE 120 to indicate that the PDSCH / PUSCH is scheduled in a different time slot than the PDCCH.

[0091] Since BS 110 may transmit PDSCH in the same time slot as PDCCH, UE 120 needs to be able to support receiving PDSCH in the same time slot as it receives PDCCH, which may use a large amount of resources of UE 120. Figure 5A and 5B The description of FIG. 1 is used to discuss resources used by UE 120 to support reception of a PDSCH in the same time slot as that in which it receives a PDCCH.

[0092] Figure 5A According to certain aspects, a method for at least a BS (e.g., Figure 1 BS110) and UE (for example, Figure 1 The wireless communication resources 500a for communication between UEs 120 and UEs 120 are scheduled in the same time slot. For example, the wireless communication resources 500a include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In some aspects, as shown, the wireless communication resources 500a shown correspond to a single time slot n.

[0093] As shown, BS 110 transmits PDCCH 510 at a first time in slot n prior to transmitting PDSCH 512 at a second time in slot n that is later than the first time. In certain aspects, UE 120 performs blind detection on PDCCH 510 for control information, including scheduling information as discussed. Figure 5A In the example shown in , the PDCCH 510 includes a DL assignment and a row index value mapped to a scheduling offset of 0, which means that the PDSCH 512 is in the same slot n as the PDCCH 510. It takes a while for the UE 120 to process the PDCCH 510 to decode and process the control information.

[0094] like Figure 5A, the PDCCH processing time extends beyond the start of the PDSCH 512 in slot n. In certain aspects, the UE 120 may begin decoding and processing the PDSCH 512 only after it has processed the PDCCH 510. In particular, without processing the PDCCH 510, the UE 120 does not know when the PDSCH 512 is scheduled (e.g., the time domain resources for the PDSCH 512) or the frequency domain resources for the PDSCH 512 for a particular UE 120. Since the UE 120 does not have information about the resources on which the PDSCH 512 is scheduled before processing the PDCCH 510, but the PDSCH 512 may be scheduled before processing the PDCCH 510, the UE 120 needs to store (e.g., buffer) all signals that may correspond to the PDSCH 512 received on the downlink from the time after the PDCCH 510 ends (or after the gap period after the PDCCH 510 ends) to the time when the PDCCH 510 is completely processed. In particular, the UE 120 needs to buffer such received signals because only after the PDCCH 510 is completely processed can the UE 120 determine whether the received signal includes the PDSCH 512 for the UE 120 and process the portion of the received signal that includes the PDSCH 512 for the UE 120. Large memory resources are used to store the entire received signal because the UE-specific resources are unknown until the UE decodes the PDCCH 510. This additional use of processing power and memory reduces the capabilities of the UE.

[0095] Figure 5B According to certain aspects, a method for at least a BS (e.g., Figure 1 BS110) and UE (for example, Figure 1 Wireless communication resource 500b is similar to 500a except that the PDSCH is not sent in the same time slot n as the PDCCH 510. Figure 5B In the example shown in , the PDCCH 510 includes DCI and a row index value mapped to a scheduling offset greater than 0, which means that the PDSCH is in a different time slot from the PDCCH 510 .

[0096] UE 120 does not have information about the resources on which PDSCH is scheduled before processing PDCCH 510, and still has to assume that PDSCH may be scheduled before processing PDCCH 510, so UE 120 still needs to store (e.g., buffer) all signals that may correspond to PDSCH received on the downlink from the time after PDCCH 510 ends (or after the gap period after PDCCH 510 ends) to the time when PDCCH 510 is completely processed. Only after PDCCH 510 is completely processed does UE 120 determine that PDSCH is not in slot n, and then UE 120 can discard the buffer. Therefore, large memory resources are used to buffer the entire received signal that is actually not used. In addition, the receiver components of UE 120 (e.g., RF / IF components, such as transceiver 254) are powered and in active mode to actually receive signals on the downlink from the time after the end of PDCCH 510 (or after the gap period after the end of PDCCH 510) to the time when PDCCH 510 is fully processed, and can be powered down (e.g., enter sleep mode) only after PDCCH 510 is fully processed and UE 120 determines that it does not have to receive additional signals in time slot n. This may result in additional power consumption and use of resources of the receiving components.

[0097] Therefore, certain aspects of this document provide techniques for adjusting scheduling offsets for wireless communications. In particular, certain aspects provide for dynamically managing scheduling offsets used by UE 120 to prevent the use of any scheduling offsets having one or more specific values. For example, in certain aspects, the present technology provides for dynamically managing scheduling offsets used by UE 120 to prevent the use of any scheduling offsets having a value of zero.

[0098] Figure 6 According to certain aspects, a method for at least a BS (e.g., Figure 1 BS110) and UE (for example, Figure 1 The wireless communication resources 600 are cross-slot scheduling for communication between UEs 120 of the wireless communication network 600. For example, the wireless communication resources 600 include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In some aspects, as shown, the wireless communication resources 600 shown correspond to time slot n and time slot n+1.

[0099] As shown, BS 110 transmits PDCCH 610 at a first time in time slot n before transmitting a corresponding PDSCH 612 at a second time in time slot n+1. Figure 6In the example shown in , the PDCCH 610 includes DCI and a row index value mapped to a scheduling offset of 1, which means that the PDSCH 612 is 1 slot later than the slot including the PDCCH 610.

[0100] In some aspects, BS110 configures UE 120 to prevent the use of any scheduling offset having a value of zero. Therefore, UE 120 knows that PDSCH 612 cannot be located in the same time slot as PDCCH 610. Therefore, UE 120 does not need to store any received signal that may correspond to PDSCH from the time after PDCCH 610 ends (or after the gap period after PDCCH 610 ends) to the time when PDCCH 610 is fully processed, because PDSCH cannot exist during this time. Therefore, advantageously, memory resources are not used to buffer the entire received signal, thereby saving storage efficiency. In addition, in some aspects, since PDSCH 612 will not need to be received in time slot n, UE 120 can power down the receiving component after PDCCH 610 ends in the remainder of time slot n, even before PDCCH 610 is fully processed. This advantageously reduces the power consumption at UE 120.

[0101] In certain aspects, BS 110 sends an indication to UE 120 to dynamically change the scheduling offset value configured at UE 120 (such as in a time domain resource allocation table) to prevent the use of any scheduling offset having one or more specific values ​​(e.g., zero). In certain aspects, the indication is sent by BS 110 to UE 120 via L1 and / or L2 signaling (e.g., in DCI or medium access control-control element (MAC-CE)). Such signaling can have reduced latency compared to other signaling such as RRC signaling.

[0102] UE 120 receives the indication and modifies its time domain resource allocation configuration (e.g., time domain resource allocation table) to prevent any configuration (e.g., entry) from being used to indicate a scheduling offset of at least a first value (such as less than the first value) or multiple values. In some aspects, the time domain resource allocation configuration (e.g., time domain resource allocation table) is modified so that no configuration (e.g., entry) includes a scheduling offset of at least the first value. In another aspect, UE 120 determines based on the indication that any configuration having a scheduling offset of at least the first value is not used for scheduling by BS 110.

[0103] In certain aspects, the indication includes an offset value greater than zero (e.g., corresponding to a maximum of at least the first value). The UE 120 then adds the offset value to each scheduling offset of each configuration of the time domain resource allocation configuration. For example, where the offset value is x, the UE 120 adds x to Figure 4 Each row of table 400 is for each schedule offset.

[0104] In some aspects, the indication includes at least a first value. Then, the UE 120 determines that any configuration of the scheduling offset having at least the first value is not used for scheduling by the BS 110. For example, in the case where at least the first value is 0, Figure 7 Table 700 (similar to Figure 4 Rows 1 and 2 of Table 400) will not be used for scheduling.

[0105] In certain aspects, using an indication such as an offset value or at least the first value saves communication resources because less data is transmitted from the BS 110 to the UE 120 than sending an entire new time domain resource allocation configuration.

[0106] In some aspects, the indication of dynamically changing the scheduling offset value sent by BS110 causes UE 120 to modify its time domain resource allocation configuration only for a period of time. Therefore, after this period of time, UE 120 reverts to using an unmodified time domain resource allocation configuration (e.g., a time domain resource allocation table without adding an offset value, using all configurations, etc.). In some aspects, the duration of the time period is preconfigured at UE 120, such as during manufacturing, OTA update, etc. In some aspects, the duration of the time period is configured at UE 120, such as using RRC signaling. In some aspects, the indication of the duration of the time period is included in the indication of dynamically changing the scheduling offset value sent by BS110. In some aspects, the duration of the time period is until BS 110 sends another indication to UE 120 about ending the dynamic change.

[0107] Example of cross-slot scheduling adaptation based on carrier group

[0108] In an example of wireless communication involving carrier aggregation (CA), a UE (e.g., Figure 1In some cases, the wireless communication may be characterized by intra-band CA, where the UE 120a may use the same transceiver hardware components for wireless communication across multiple CCs. However, if the UE 120a utilizing CA uses cross-slot scheduling, and if at least one CC does not provide an indication of a scheduling offset (e.g., k0) greater than 0, the transceiver hardware components of the UE 120a must remain in an active power state due to monitoring at least one CC. Therefore, in order to save power, it would be beneficial if the monitoring periodicity and timing of the UE 120a are aligned across multiple CCs. In this way, the monitoring periods of multiple CCs are known, and the UE 120a can reduce the power of the transceiver hardware components during the time when the UE 120a does not need to monitor multiple CCs.

[0109] In certain aspects, UE 120a is configured to receive a time domain configuration (eg, Figure 4 The time domain resource allocation table 400 of the embodiment of the present invention is a time domain resource allocation table 400, the time domain configuration including one or more offset values ​​of the time domain resources relative to the reception of the physical downlink control channel PDCCH. For example, in the case of cross-time slot scheduling, the PDCCH may include a downlink scheduling assignment, which provides one or more bit values ​​corresponding to the offset value in the time domain configuration (e.g., k0 for PDSCH or k2 for PUSCH). Therefore, each of the one or more offset values ​​indicates a scheduling offset, which indicates the number of time slots offset from the reception of the PDCCH including the downlink scheduling assignment.

[0110] In certain aspects, the UE may be pre-configured with a scheduling adaptation configuration. In some examples, the scheduling adaptation configuration may include one or more minimum offset values ​​relative to reception of the PDCCH, wherein each of the one or more minimum offset values ​​corresponds to one or more CCs in the CC group and indicates a minimum scheduling offset, the minimum scheduling offset indicating a minimum number of minislots offset from reception of the PDCCH.

[0111] In some examples, UE 120a may receive a scheduling adaptation configuration from BS 110. In some examples, UE 120a may receive the scheduling adaptation configuration and the time domain configuration separately. In one example, BS 110 may determine the CC group based on which frequency bands each CC belongs to. That is, UE 120a may receive information indicating the carriers forming the carrier group from BS 110. For example, BS 110 may group multiple CCs, where the multiple CCs share the same digital scheme during wireless communication, are in the same frequency band (e.g., intra-band CA), and / or share the same transceiver components of the UE (e.g., Figure 4transceivers 254a to 254r, antennas 252a to 252r).

[0112] Alternatively, UE 120a may generate and send a report to BS 110, wherein the report indicates a preferred CC grouping. That is, UE 120a may send information indicating the carriers forming the carrier group to BS 110. Therefore, in some examples, BS 110 may provide scheduling adaptation configuration to UE 120a based on the preferred CC grouping of UE 120a. It should be noted that in some examples, UE 120a may be configured with multiple carrier groups and may therefore communicate on more than one CC group. In some cases, more than one CC group may include overlapping CCs in two or more groups. For example, at least one carrier may be included in at least two of the multiple carrier groups.

[0113] In certain aspects, UE 120a may receive the time domain configuration from BS 110 via layer 3 signaling (e.g., radio resource control (RRC) signaling), while in some examples, UE 120a may receive the scheduling adaptation configuration via layer 1 or layer 2 signaling (e.g., in downlink control information (DCI) or medium access control (MAC) control element (CE)) from BS 110. In some examples, the scheduling adaptation configuration may be delivered and received by UE 120a via any CC in a CC group.

[0114] In some examples, UE 120a may monitor control signaling on an anchor CC (or "anchor carrier"), and / or send and receive control information and data on an anchor CC. In one example, UE 120a sends and receives control information related to the anchor CC and other CCs in the group via the anchor CC. The anchor CC may be selected based on CC quality or by network selection. In some examples, communications on the anchor CC take precedence over other CCs in the group. For example, when the anchor CC is receiving or transmitting, respectively, within a specific time period, UE 120a may prevent CCs other than the anchor CC from transmitting or receiving. That is, UE 120a may prevent other CCs from transmitting when the anchor CC is receiving, or prevent other CCs from receiving when the anchor CC is transmitting. Therefore, in some aspects, the scheduling adaptation configuration may be received by UE 120a via an anchor CC in a CC group. In some examples, if there are multiple groups, an anchor CC may be configured for each CC group. Alternatively, there may be only one anchor CC (eg, PCell or PSCell), in which case UE 120a may identify the anchor CC via a scheduling adaptation configuration from BS 110 .

[0115] Figure 8An example scheduling adaptation configuration table 800 for PDSCH is shown. It should be noted that the UE 120a may be configured with a similar scheduling adaptation configuration table for PUSCH, or may be configured with a single scheduling adaptation configuration table for both PDSCH and PUSCH.

[0116] As shown, the scheduling adaptation configuration table 800 includes columns corresponding to CCs in a particular group (e.g., in some examples, the scheduling adaptation configuration table 800 corresponds to a single CC group), a set 0 corresponding to a set of minimum offset values ​​for same-time slot scheduling, and a set 1 corresponding to a set of minimum offset values ​​for cross-time slot scheduling. Each row corresponds to a CC in a CC group. In this example, there are four rows corresponding to four different component carriers in a CC group (e.g., CC1, CC2, CC3, CC4). In some aspects, the table 800 includes additional sets (e.g., set 2, set 3, etc.) and more or fewer CCs.

[0117] In the example table, the minimum offset value (e.g., minimum k0 value) for same-slot scheduling for each CC in the CCs is equal to 0, while the minimum offset value for cross-slot scheduling for each CC in the CCs is greater than 0. Therefore, each CC in the CC group has a minimum scheduling offset associated therewith in terms of the slot offset for each of the same-slot scheduling and the cross-slot scheduling.

[0118] In some examples, UE 120a may receive a PDCCH that includes one or more bits configured to indicate which set (e.g., set 0 or set 1) to use to monitor the corresponding PDSCH. Figure 8 In the example shown in , there are only two sets, so the indication may be conveyed by a single bit. In some examples, one or more bits may be included in the DCI transmitted by BS 110 and received by UE 120a.

[0119] In one example, if the bit is set to 0, there is no cross-slot scheduling adaptation. Therefore, any entry in the time domain configuration can be used to schedule the corresponding PDSCH or PUSCH. If the bit is set to 1, cross-slot scheduling can be used for all CCs in the CC group. Therefore, the minimum offset value of the corresponding carrier is determined based on the set indicated by BS 110 to UE 120a. For example, referring to Figure 4 The time domain configuration table and Figure 8800, UE 120a may determine to monitor according to row indexes 3 and 4 of time domain configuration table 400. This is because the minimum offset value (e.g., minimum k0 value) of CC1 and CC2 is equal to "1", which means that row indexes 1 and 2 of time domain configuration table 400 cannot be used (k0 values ​​of row indexes 1 and 2 are both equal to "0"). However, row indexes 3 and 4 of time domain configuration table 400 are "1" and "2", respectively. Therefore, CC1 and CC2 can utilize scheduling of both indexes 3 and 4, while CC3 and CC4 can only utilize index 4.

[0120] Therefore, in certain aspects, UE 120a may determine, for each CC in the CC group, that at least one of the one or more offset values ​​is greater than or equal to the minimum offset value of the corresponding carrier. In one example, the offset value of row index 3 of the time domain configuration table 400 is equal to "1". Here, because the minimum offset values ​​of both CC1 and CC2 are equal to 1, UE 120a may determine that the offset value or row index 3 is greater than or equal to the minimum offset value of both CC1 and CC2. Therefore, monitoring PDSCH on CC1 and CC2 may be offset by at least one time slot (k0) from the PDCCH that schedules downlink communications. Similarly, monitoring PDSCH on CC3 and CC4 may be offset by at least two time slots from the PDCCH that schedules downlink communications. That is, for each carrier in the carrier group, UE 120a may monitor PDSCH at a time domain resource corresponding to at least one of the one or more offset values ​​that is greater than or equal to the minimum offset value of the corresponding carrier.

[0121] In certain aspects, the UE 120a may determine to monitor the PDCCH of each CC in the CC group based on the scheduled PDCCH monitoring period of the first CC in the CC group having the lowest periodicity of the scheduled PDCCH monitoring period in the CC group. For example, the UE 120a may determine the periodicity of each CC in the CC group, then determine which CC in the CC group has the lowest (or most frequent) monitoring periodicity, and monitor the PDCCH of each CC in the CC group according to the lowest monitoring periodicity.

[0122] For example, Fig. 9A According to certain aspects, a method for at least a BS (e.g., Figure 1 BS 110) and UE (e.g., Figure 1 The wireless communication resources 900 may be used to monitor the communication between the UE 120 and the wireless communication resource 900. For example, the wireless communication resources 900 include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In some aspects, as shown, the wireless communication resources 900 shown correspond to a plurality of consecutive time slots.

[0123] exist Fig. 9A In the example of , the CC group may include CC1 and CC2. CC1 has a PDCCH monitoring periodicity of two time slots. For example, UE 120a monitors CC1 for PDCCH every two time slots. In contrast, CC2 has a PDCCH monitoring periodicity of one time slot. For example, UE 120a monitors CC2 for PDCCH every time slot. Therefore, in this example, UE 120a may determine to monitor both CC1 and CC2 for PDCCH based on the lowest monitoring periodicity (which is one time slot).

[0124] In some examples, when UE 120a is not monitoring the PDCCH, UE 120a powers down the transceiver components of UE 120a. Fig. 9A The "RF State" row is shown, which shows the time and duration of the transceiver power state. In this example, the UE 120a powers up the transceiver components during the lowest periodicity to monitor the PDCCH of each CC in the CC group (e.g., CC1 and CC2). In some examples, if CC1 and CC2 are part of a carrier aggregation (CA) communication, the amount of power used by the UE 120a will be reduced by cycling the power to the transceiver components.

[0125] In some examples, UE 120a may determine to monitor the PDCCH of each CC in the CC group based on the maximum configured subcarrier spacing (SCS) for monitoring the PDCCH in the CC group. For example, UE 120a may determine the SCS of each CC in the CC group, then determine which CC in the CC group has the largest SCS, and monitor the PDCCH of each CC in the CC group according to the largest SCS.

[0126] For example, Fig. 9B According to certain aspects, a method for at least a BS (e.g., Figure 1 BS 110) and UE (e.g., Figure 1 The wireless communication resources 950 may include a monitoring period of wireless communication resources 950 for communication between UEs 120 and UEs 120. For example, the wireless communication resources 950 include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In some aspects, as shown, the wireless communication resources 950 shown correspond to a plurality of consecutive time slots.

[0127] exist Fig. 9B In the example of , the CC group may include CC1 and CC2. CC2 has an SCS interval that is twice as large as CC1 (e.g., the time slot duration of CC2 is half the time slot duration of CC1). Therefore, UE 120a can use the larger subcarrier spacing of CC2 to monitor each of the overlapping CC1 and CC2 time slots.

[0128] Similar to Fig. 9A , when UE 120a is not monitoring the PDCCH, UE 120a may power down the transceiver components of UE 120a. For example, Fig. 9B The "RF State" row is shown, which shows the time and duration of the transceiver power state. In this example, UE 120a powers up the transceiver components during the lowest periodicity to monitor the PDCCH of each CC in the CC group (e.g., CC1 and CC2) during the largest subcarrier spacing.

[0129] In some examples, UE 120a may determine the PDCCH for each CC in the monitoring CC group based on both the CC with the lowest periodicity and the CC with the largest SCS.

[0130] In certain aspects, UE 120a may determine to monitor the PDCCH of each CC in the CC group based on whether one CC in the CC group is an anchor CC. For example, UE 120a may determine to monitor the PDCCH of each CC in the CC group based on the scheduled PDCCH monitoring period of the anchor CC. In such an example, UE 120a may avoid monitoring the PDCCH on any scheduled PDCCH monitoring period of any CC in the CC group that does not overlap with the scheduled PDCCH monitoring period of the anchor CC. In some examples, when UE 120a avoids monitoring the PDCCH, UE 120a powers down the transceiver components of UE 120a.

[0131] In certain aspects, UE 120a may monitor the PDCCH during any scheduled PDCCH monitoring period of any CC in the CC group that does not overlap with the scheduled PDCCH monitoring period of the first carrier and overlaps with the period for monitoring the PDSCH on any other CC in the group. In some examples, UE 120a may determine to monitor the PDCCH on each carrier in the carrier group during the scheduled PDCCH monitoring period of the first carrier.

[0132] For example, Fig. 10A According to certain aspects, a method for at least a BS (e.g., Figure 1 BS 110) and UE (e.g., Figure 1 The wireless communication resources 1000 may include a monitoring period of the wireless communication resources 1000 for communication between the UEs 120 and the wireless communication resources 1000. For example, the wireless communication resources 1000 include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In certain aspects, as shown, the wireless communication resources 1000 shown correspond to a plurality of consecutive time slots.

[0133] In this example, CC1 is an anchor CC with a monitoring periodicity of two slots, and CC2 is a non-anchor CC with a monitoring periodicity of one slot. In this example, although CC2 has the lowest monitoring periodicity, the UE 120a may adopt the periodicity of the anchor slot (e.g., CC1) and ignore certain PDCCH instances of CC2 (shown as crossed-out PDCCH instances). It should be noted that the transceiver components may be powered up and down according to the anchor CC monitoring periodicity.

[0134] In another example, Fig. 10B According to certain aspects, a method for at least a BS (e.g., Figure 1 BS110) and UE (for example, Figure 1 The wireless communication resources 1050 may include a monitoring period for wireless communication resources 1050 for communication between UEs 120 and UEs 120. For example, the wireless communication resources 1050 include time along a horizontal axis (e.g., an X-axis) and frequency along a vertical axis (e.g., a Y-axis). In some aspects, as shown, the wireless communication resources 1050 shown correspond to a plurality of consecutive time slots.

[0135] In this example, CC1 is an anchor CC with a monitoring periodicity of one slot and a smaller SCS relative to CC2, while CC2 is a non-anchor CC also with a monitoring periodicity of one slot. In this example, the UE 120a may adopt the periodicity of the anchor slot (e.g., CC1) and ignore certain PDCCH instances of CC2 (shown as crossed-out PDCCH instances). It should be noted that transceiver components may be powered up and down according to the anchor CC monitoring periodicity.

[0149] In certain aspects, the one or more bits are received via downlink control information (DCI).

[0150] In certain aspects, a first carrier in the carrier group is an anchor carrier, and operations 1100 include determining to monitor a PDCCH of each carrier in the carrier group based on a scheduled PDCCH monitoring period for the first carrier.

[0151] In certain aspects, determining to monitor the PDCCH of each carrier in the carrier group based on the scheduled PDCCH monitoring period of the first carrier includes: avoiding monitoring the PDCCH on any scheduled PDCCH monitoring period of any carrier in the carrier group that does not overlap with the scheduled PDCCH monitoring period of the first carrier.

[0152] In certain aspects, refraining from monitoring the PDCCH includes powering down transceiver components of the UE.

[0153] In certain aspects, avoiding monitoring the PDCCH during any scheduled PDCCH monitoring period of any carrier in the carrier group that does not overlap with the scheduled PDCCH monitoring period of the first carrier includes monitoring the PDCCH during any scheduled PDCCH monitoring period of any carrier in the carrier group that does not overlap with the scheduled PDCCH monitoring period of the first carrier and overlaps with the period for monitoring the PDSCH.

[0157] Fig.12 Operations 1200 of a method of wireless communication performed at a BS in accordance with certain aspects of the present disclosure are shown.

[0212] Additional considerations

[0213] The techniques described herein can be used for various wireless communication technologies, such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), Advanced LTE (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), CDMA2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. CDMA2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network may implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). NR is an emerging wireless communication technology under development.

[0214] The technology described herein can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For the sake of clarity, although the terms commonly associated with 3G, 4G and / or 5G wireless technologies may be used herein to describe various aspects, various aspects of the present disclosure may be applied to communication systems based on other generations.

[0215] In 3GPP, the term "cell" may refer to the coverage area of ​​a Node B (NB) and / or a NB subsystem serving the coverage area, depending on the context in which the term is used. In NR systems, the terms "cell" and BS, next generation Node B (gNB or gNodeB), access point (AP), distributed unit (DU), carrier or transmit receive point (TRP) may be used interchangeably. BSs may provide communication coverage for macro cells, pico cells, femto cells and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for users in a residence, etc.). 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 called a femto BS or a home BS.

[0216] UE may also be referred to as a mobile station, a terminal, an access terminal, a subscriber unit, a station, a customer premises equipment (CPE), a cellular phone, 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, an appliance, a medical device or medical apparatus, a biometric sensor / device, a wearable device (such as a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music device, a video device, a satellite radio unit, etc.), a vehicle 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. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node can provide, for example, a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs can be considered Internet of Things (IoT) devices, which can be narrowband IoT (NB-IoT) devices.

[0217] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, frequency bins, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are sent in the frequency domain using OFDM and in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing of the subcarriers can be 15kHz and the minimum resource allocation (referred to as a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be partitioned into subbands. For example, a subband may cover 1.8 MHz (e.g., 6 RBs), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively. In LTE, the basic transmission time interval (TTI) or packet duration is a 1 ms subframe.

[0218] NR can utilize OFDM with CP on both uplink and downlink, and includes support for half-duplex operation using TDD. In NR, the subframe is still 1ms, but the basic TTI is called a time slot. A subframe contains a variable number of time slots (e.g., 1, 2, 4, 8, 16...time slots), depending on the subcarrier spacing. NR RB is 12 continuous frequency subcarriers. NR can support a basic subcarrier spacing of 15KHz, and other subcarrier spacings can be defined relative to the basic subcarrier spacing, such as 30kHz, 60kHz, 120kHz, 240kHz, etc. Symbol and time slot lengths scale with subcarrier spacing. The CP length also depends on the subcarrier spacing. Beamforming can be supported and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. In some examples, the MIMO configuration in DL can support up to 8 transmit antennas, with up to 8 streams for multi-layer DL transmission and up to 2 streams for each UE. In some examples, multi-layer transmission with up to 2 streams per UE can be supported. Aggregation of multiple cells with up to 8 serving cells may be supported.

[0219] In some examples, access to the air interface can be scheduled. The scheduling entity (e.g., BS) allocates resources for communication between some or all devices and apparatuses in its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, the subordinate entity utilizes the resources allocated by the scheduling entity. The base station is not the only entity that can be used as a scheduling entity. In some examples, the UE may be used as a scheduling entity, and resources for one or more subordinate entities (e.g., one or more other UEs) may be scheduled, and other UEs may utilize the resources scheduled by the UE for wireless communication. In some examples, the UE may be used as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, the UEs may also communicate directly with each other.

[0220] In some examples, two or more slave entities (e.g., UEs) can communicate with each other using side link signals. Real-life applications of such side link communications may include public safety, proximity services, UE-to-network relays, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical mesh networks, and / or various other appropriate applications. Typically, a side link signal may refer to a signal that is transmitted from one slave entity (e.g., UE1) to another slave entity (e.g., UE2) without the need for relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, a licensed spectrum may be used to transmit a side link signal (unlike wireless local area networks that typically use unlicensed spectrum).

[0221] The method disclosed herein includes one or more steps or actions for implementing the method. These method steps and / or actions may be interchangeable with each other without departing from the scope of the claims. In other words, unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions may be modified without departing from the scope of the claims.

[0222] As used herein, a phrase referring to "at least one of" a list of items refers to any combination of those items, including single members. For example, "at least one of a, b, or c" is intended to cover a, b, c, ab, ac, bc, and abc, as well as any combination 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).

[0223] As used herein, the term "determining" includes a wide variety of actions. For example, "determining" may include calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, a database, or another data structure), ascertaining, and the like. Furthermore, "determining" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like. Furthermore, "determining" may include resolving, selecting, choosing, establishing, and the like.

[0224] The previous description is provided to enable any person skilled in the art to implement the various aspects described herein. Various modifications to these aspects will be apparent to those skilled in the art, and the general principles defined herein can be applied to other aspects. Therefore, the claims are not intended to be limited to the aspects shown herein, but are given the full scope consistent with the text of the claims, wherein, unless otherwise specifically stated, reference to an element in the singular form is not intended to mean "one and only one", but "one or more".

In addition, nothing disclosed herein is intended to be dedicated to the public, regardless of whether such disclosure is explicitly recorded in the claims. No claim element is to be interpreted according to the provisions of 35 U.S.C. § 112, paragraph 6, unless the element is explicitly recorded using the phrase "unit for...", or in the case of a method claim, the element is recorded using the phrase "step for...".

[0225] The various operations of the methods described above may be performed by any suitable unit capable of performing the corresponding functions. These units may include various hardware and / or software components and / or modules, including but not limited to: circuits, application specific integrated circuits (ASICs) or processors. Typically, where there are operations shown in the figures, those operations may have corresponding paired functional unit components with similar numbers.

[0226] The various illustrative logic blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or executed using a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in an alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0227] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. Depending on the specific application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may link together various circuits including a processor, a machine-readable medium, and a bus interface. In addition, the bus interface may also be used to connect a network adapter to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In the user terminal 120 (see Figure 1 ), a user interface (e.g., a keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits such as timing sources, peripherals, voltage regulators, power management circuits, etc., which are well known in the art and therefore will not be described any further. The processor may be implemented using one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits that can execute software. Those skilled in the art will recognize how to best implement the functionality described for the processing system depending on the specific application and the overall design constraints imposed on the entire system.

[0228] If implemented with software, the functions may be stored on or transmitted through a computer-readable medium as one or more instructions or codes. Whether referred to as software, firmware, middleware, microcode, hardware description language or other terms, software should be broadly interpreted as meaning instructions, data or any combination thereof. Computer-readable media include both computer storage media and communication media, and communication media include any media that helps to transfer a computer program from one place to another. The processor may be responsible for managing the bus and general processing, which includes executing software modules stored on a machine-readable storage medium. A computer-readable storage medium may be coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium. In an alternative, the storage medium may be a component of the processor. For example, a machine-readable medium may include a transmission line, a carrier waveform modulated by data, and / or a computer-readable storage medium having instructions stored thereon that is separated from a wireless node, all of which may be accessed by a processor through a bus interface. Alternatively or in addition, a machine-readable medium or any part thereof may be integrated into a processor, for example, the case may be a cache and / or a general register stack. For example, examples of machine-readable storage media may include RAM (random access memory), flash memory, ROM (read-only memory), PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. Machine-readable media may be embodied in a computer program product.

[0229] A software module may include a single instruction or many instructions, and may be distributed over several different code segments, distributed among different programs, and distributed across multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a sending module and a receiving module. Each software module may be located in a single storage device or distributed across multiple storage devices. For example, when a triggering event occurs, a software module may be loaded from a hard drive into a RAM. During the execution of a software module, a processor may load some of the instructions into a cache to increase access speed.
