A base station may send first information via a first communication opportunity in an SPS opportunity and send second information via a second communication opportunity in the same SPS opportunity. A wireless communication device may monitor all communication opportunities in an SPS opportunity to decode information sent in two or more of the communication opportunities in the SPS opportunity.

[0002] This application is the Chinese national phase of PCT patent application number PCT / CN2020 / 088659 filed on May 6, 2020. Technical Field

[0003]

[0006] Generally speaking, aspects of the present disclosure relate to wireless communications, and more particularly, to transmitting information via multiple communication opportunities in semi-persistent scheduling opportunities. Background Art

[0004] A next generation wireless communication system (e.g., 5GS) may include a 5G core network and a 5G radio access network (RAN) (e.g., new radio (NR)-RAN). NR-RAN supports communication via one or more cells. For example, a wireless communication device (e.g., user equipment (UE)) may access a first cell of a first base station (BS) (e.g., gNB) and / or access a second cell of a second BS.

[0005] The BS may schedule access to a cell to support access by multiple UEs. For example, the BS may allocate different resources (eg, time domain and frequency domain resources) to different UEs operating within a cell of the BS.

[0006] As the demand for mobile broadband access continues to increase, research and development continues to advance communication technologies, particularly including technologies for enhancing communications within wireless networks, not only to meet the growing demand for mobile broadband access, but also to advance and enhance the user experience of mobile communications. Summary of the invention

The innovations described herein are intended to be implemented in a variety of devices, chip-level components, systems, distributed arrangements, end-user devices, etc., having different sizes, shapes, and configurations.

[0036] The various concepts presented throughout this disclosure may be implemented across a wide variety of telecommunication systems, network architectures, and communication standards.The following description provides illustrative examples of various aspects of the disclosure without limiting them.

[0037] Figure 1 1 is a schematic diagram of a wireless communication system 100 according to some aspects of the present disclosure. The wireless communication system 100 includes three interacting domains: a core network 102, a radio access network (RAN) 104, and at least one scheduled entity 106. In the subsequent discussion, the at least one scheduled entity 106 may be referred to as a user equipment (UE) 106. The RAN 104 includes at least one scheduling entity 108. In the subsequent discussion, the at least one scheduling entity 108 may be referred to as a base station (BS) 108. By means of the wireless communication system 100, the UE 106 may be enabled to perform data communications with an external data network 110, such as (but not limited to) the Internet.

[0038] The RAN 104 may implement any one or more suitable wireless communication technologies to provide radio access to the UE 106. As an example, the RAN 104 may operate according to the 3rd Generation Partnership Project (3GPP) New Radio (NR) specification (often referred to as 5G). As another example, the RAN 104 may operate according to a hybrid of 5G NR and Evolved Universal Terrestrial Radio Access Network (eUTRAN) standards (often referred to as LTE). 3GPP refers to this hybrid RAN as the Next Generation RAN or NG-RAN. Of course, many other examples may be utilized within the scope of the present disclosure.

[0039] As shown, the RAN 104 includes a plurality of base stations 108. In a broad sense, a base station is a network element in a radio access network that is responsible for radio transmission and reception to or from a UE in one or more cells. In different technologies, standards, or contexts, those skilled in the art may refer to a base station as a base transceiver (BTS), a radio base station, a radio transceiver, a transceiver functional unit, a basic service set (BSS), an extended service set (ESS), an access point (AP), a Node B (NB), an evolved Node B (eNB), a gNodeB (gNB), or some other suitable terminology.

[0040] The radio access network 104 is also shown to support wireless communications for multiple mobile devices. In the 3GPP standard, a mobile device may be referred to as a user equipment (UE), but those skilled in the art may also refer to it as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, a remote terminal, a handset, a terminal, a user agent, a mobile client, a client, or some other appropriate term. A UE may be a device that provides a user with access to network services.

[0041] Within this document, a "mobile" device does not necessarily need to have the ability to move, and it can be stationary. The term mobile device or mobile device broadly refers to a wide variety of devices and technologies. A UE may include multiple hardware structural components whose size, shape, and arrangement are configured to facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc. that are electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile stations, cellular (cell) phones, smart phones, session initiation protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablet devices, personal digital assistants (PDAs), and a variety of embedded systems, for example, corresponding to the "Internet of Things" (IoT). In addition, a mobile device may be a car or other means of transportation, a remote sensor or actuator, a robot or robotic device, a satellite radio unit, a global positioning system (GPS) device, an object tracking device, a drone, a multi-rotor helicopter, a quadcopter, a remote control device, a consumer device such as glasses, a wearable camera, a virtual reality device, a smart watch, a health or fitness tracker, a digital audio player (e.g., an MP3 player), a camera, a game console, and / or a wearable device. In addition, the mobile device may be a digital home or smart home device, such as home audio, video and / or multimedia devices, home appliances, vending machines, smart lighting, home security systems, smart meters, etc. In addition, the mobile device may be a smart energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls power (e.g., smart grid), lighting, water, etc.; industrial automation and enterprise devices; logistics controllers; agricultural equipment; military defense equipment, vehicles, aircraft, ships and weapons, etc. Further, the mobile device may provide connected medicine or telemedicine support (i.e., remote health care). Telemedicine devices may include telemedicine monitoring devices and telemedicine management devices, whose communications may be given priority or priority access relative to other types of information, for example, in terms of priority access for the transmission of critical service data, and / or in terms of the associated QoS for the transmission of critical service data.

[0042] Wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions from a base station (e.g., base station 108) to one or more UEs (e.g., UE 106) over an air interface can be referred to as downlink (DL) transmissions. According to certain aspects of the present disclosure, the term downlink can refer to point-to-multipoint transmissions originating from a scheduling entity (further described below; e.g., base station 108). Another way to describe the scheme can be to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. According to further aspects of the present disclosure, the term uplink can refer to point-to-point transmissions originating from a scheduled entity (further described below; e.g., UE 106).

[0043] In some examples, access to the air interface may be scheduled, wherein a scheduling entity (e.g., a base station 108) allocates resources for communication between some or all devices and apparatuses within its service area or cell. In the present disclosure, as further discussed below, a scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities. That is, for scheduled communications, a UE 106 (which may be a scheduled entity) may use resources allocated by the scheduling entity 108.

[0044] Base station 108 is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more scheduled entities (e.g., one or more other UEs).

[0045] like Figure 1 As shown in , the scheduling entity 108 can broadcast downlink traffic 112 to one or more scheduled entities 106. Broadly speaking, the scheduling entity 108 is a node or device responsible for scheduling traffic in the wireless communication network, including downlink traffic 112, and in some examples, uplink traffic 116 from one or more scheduled entities 106 to the scheduling entity 108. On the other hand, the scheduled entity 106 is a node or device that receives downlink control information 114 (including but not limited to scheduling information (e.g., grants), synchronization or timing information, or other control information) from another entity in the wireless communication network (e.g., the scheduling entity 108).

[0046] In addition, uplink and / or downlink control information and / or traffic information can be divided into frames, subframes, time slots and / or symbols in time. As used herein, a symbol can refer to a time unit in which each carrier carries a resource element (RE) in an orthogonal frequency division multiplexing (OFDM) waveform. A time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1ms. Multiple subframes or time slots can be grouped together to form a single frame or radio frame. Of course, these definitions are not required, and any appropriate scheme for organizing a waveform can be utilized, and the various time divisions of the waveform can have any appropriate duration.

[0047] Typically, base stations 108 may include a backhaul interface for communicating with a backhaul portion 120 of a wireless communication system. Backhaul 120 may provide a link between base stations 108 and core network 102. Additionally, in some examples, a backhaul network may provide interconnections between respective base stations 108. Various types of backhaul interfaces may be employed, such as a direct physical connection, a virtual network, or a backhaul interface using any suitable transport network.

[0048] The core network 102 may be part of the wireless communication system 100 and may be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 may be configured according to 5G standards (e.g., 5GC). In other examples, the core network 102 may be configured according to 4G Evolved Packet Core (EPC) or any other appropriate standard or configuration.

[0049] Figure 2 is a conceptual diagram of an example of a radio access network (RAN) 200 according to some aspects of the present disclosure. In some examples, the RAN 200 can be similar to the RAN described above and in Figure 1 The geographic area covered by the RAN 200 may be divided into a number of cellular regions (cells) that a user equipment (UE) may uniquely identify based on an identity broadcast from an access point or base station. Figure 2 Macro cells 202, 204, and 206 and small cells 208 are shown, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors in a cell are served by the same base station. A radio link in a sector can be identified by a single logical identifier belonging to the sector. In a cell divided into multiple sectors, multiple sectors in a cell can be formed by multiple groups of antennas, each of which is responsible for communicating with a UE in a portion of the cell.

[0050] Various base station arrangements can be used. Figure 2, two base stations 210 and 212 are shown in cells 202 and 204; and a third base station 214 is shown as controlling a remote radio head (RRH) 216 in cell 206. That is, the base station may have an integrated antenna or may be connected to an antenna or RRH by a feeder cable. In the example shown, cells 202, 204, and 206 may be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. In addition, a base station 218 is shown in a small cell 208 (e.g., a micro cell, a pico cell, a femto cell, a home base station, a home node B, a home eNodeB, etc.), which may overlap with one or more macro cells. In this example, cell 208 may be referred to as a small cell because base station 218 supports a cell with a relatively small size. The cell size setting may be performed according to the system design and component constraints.

[0051] It is to be understood that the radio access network 200 may include any number of wireless base stations and cells. In addition, relay nodes may be deployed to extend the size or coverage area of ​​a given cell. Base stations 210, 212, 214, 218 provide wireless access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 may be similar to those described above and in Figure 1 The base station / scheduling entity 108 shown in FIG.

[0052] Within the RAN 200, cells may include UEs that may communicate with one or more sectors of each cell. In addition, each base station 210, 212, 214, and 218 may be configured to provide a core network (e.g., such as a core network) for all UEs in the corresponding cell. Figure 1 210; UEs 226 and 228 may communicate with base station 212; UEs 230 and 232 may communicate with base station 214 by way of RRH 216; and UE 234 may communicate with base station 218. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 238, 240, and / or 242 may communicate with the base stations described above and in Figure 1 The UE / scheduled entity 106 shown in FIG. 1 is the same as that shown in FIG.

[0053] In some examples, an unmanned aerial vehicle (UAV) 220 (which may be a drone or a quadcopter) may be a mobile network node and may be configured to act as a UE. For example, UAV 220 may operate in cell 202 by communicating with base station 210.

[0054] In another aspect of RAN 200, sidelink signals can be used between UEs without having to rely on scheduling or control information from a base station. For example, two or more UEs (e.g., UE 226 and 228) can communicate with each other using peer-to-peer (P2P) or sidelink signals 227 without relaying the communication through a base station (e.g., base station 212). In another example, UE 238 is shown as communicating with UE 240 and 242. Here, UE 238 can act as a scheduling entity or a primary sidelink device, and UE 240 and 242 can act as a scheduled entity or a non-primary (e.g., auxiliary) sidelink device. In another example, a UE can act as a scheduling entity in a device-to-device (D2D), peer-to-peer (P2P) or vehicle-to-vehicle (V2V) network and / or in a mesh network. In the mesh network example, UE 240 and 242 can optionally communicate directly with each other in addition to communicating with UE 238 (e.g., acting as a scheduling entity). Thus, in a wireless communication system having scheduled access to time-frequency resources and having a cellular configuration, a P2P configuration, or a mesh configuration, a scheduling entity and one or more scheduled entities can communicate using the scheduled resources. In some examples, the sidelink signal 227 includes sidelink traffic (e.g., a physical sidelink shared channel) and sidelink control (e.g., a physical sidelink control channel).

[0055] In the radio access network 200, the ability of a UE to communicate independently of its location while moving is called mobility. The various physical channels between the UE and the radio access network are usually established, maintained, and released under the control of the Access and Mobility Management Function (AMF). Figure 2 ) may include a Security Context Management Function (SCMF) that manages security contexts for both control plane and user plane functions and a Security Anchor Function (SEAF) that performs authentication.

[0056] The radio access network 200 can use DL-based mobility or UL-based mobility to implement mobility and handover (i.e., the conversion of a UE's connection from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity, or at any other time, the UE can monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Based on the quality of these parameters, the UE can maintain communication with one or more of the neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from the neighboring cell exceeds the signal quality from the serving cell within a given amount of time, the UE can perform a handoff or handover from the serving cell to the neighboring (target) cell. For example, a UE 224 (shown as a vehicle, but can be any suitable form that the UE can use) can move from a geographic area corresponding to its serving cell 202 to a geographic area corresponding to a neighboring cell 206. When the signal strength or quality from a neighbor cell 206 exceeds the signal strength or quality of its serving cell 202 for a given amount of time, the UE 224 may send a report message indicating this condition to its serving base station 210. In response, the UE 224 may receive a handover command, and the UE may undergo a handover to the cell 206.

[0057] In a network configured for UL-based mobility, the network can use the UL reference signal from each UE to select a serving cell for each UE. In some examples, base stations 210, 212, and 214 / 216 can broadcast a unified synchronization signal (e.g., a unified primary synchronization signal (PSS), a unified secondary synchronization signal (SSS), and a unified physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 can receive the unified synchronization signal, derive carrier frequency and slot timing from the synchronization signal, and send an uplink pilot or reference signal in response to the derived timing. The uplink pilot signal sent by a UE (e.g., UE 224) can be received simultaneously by two or more cells (e.g., base stations 210 and 214 / 216) within the radio access network 200. Each of these cells may measure the strength of the pilot signal, and the radio access network (e.g., one or more of the base stations 210 and 214 / 216 and / or a central node within the core network) may determine a serving cell for the UE 224. As the UE 224 moves through the radio access network 200, the network may continue to monitor the uplink pilot signals sent by the UE 224. When the signal strength or quality of the pilot signal measured by the neighboring cell exceeds the signal strength or quality measured by the serving cell, the network 200 may handover the UE 224 from the serving cell to the neighboring cell with or without notifying the UE 224.

[0058] Although the synchronization signals sent by base stations 210, 212 and 214 / 216 may be uniform, the synchronization signals may not identify a specific cell, but may identify a region of multiple cells operating on the same frequency and / or using the same timing. Using regions in a 5G network or other next generation communication network implements an uplink-based mobility framework and improves the efficiency of both the UE and the network because the number of mobility messages that need to be exchanged between the UE and the network can be reduced.

[0059] In various implementations, the air interface in the radio access network 200 may utilize a licensed spectrum, an unlicensed spectrum, or a shared spectrum. Licensed spectrum typically provides exclusive use of a portion of the spectrum by virtue of a mobile network operator purchasing a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for a government-authorized license. Although compliance with some technical rules is still typically required to access the unlicensed spectrum, in general, any operator or device may gain access. Shared spectrum may fall between licensed spectrum and unlicensed spectrum, where technical rules or restrictions may be required to access the spectrum, but the spectrum may still be shared by multiple operators and / or multiple RATs. For example, a license holder for a portion of a licensed spectrum may provide licensed shared access (LSA) to share the spectrum with other parties (e.g., with appropriate licensee-determined conditions to obtain access).

[0060] The air interface in the radio access network 200 may use one or more multiplexing and multiple access algorithms to enable simultaneous communication of various devices. For example, using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP), the 5G NR specification provides multiple access for UL transmissions from UEs 222 and 224 to the base station 210, and multiplexing of DL transmissions from the base station 210 to one or more UEs 222 and 224. In addition, for UL transmissions, the 5G NR specification provides support for discrete Fourier transform spread OFDM (DFT-s-OFDM) with CP (also referred to as single carrier FDMA (SC-FDMA)). However, within the scope of the present disclosure, multiplexing and multiple access are not limited to the above schemes, and may be provided using time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), sparse code multiple access (SCMA), resource extension multiple access (RSMA) or other appropriate multiple access schemes. In addition, multiplexing of DL transmissions from base station 210 to UEs 222 and 224 may be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM), or other suitable multiplexing schemes.

[0061] The air interface in the radio access network 200 can also utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link, in which two endpoints can communicate with each other in two directions. Full-duplex means that two endpoints can communicate with each other simultaneously. Half-duplex means that only one endpoint can send information to the other endpoint at a certain time. In a wireless link, a full-duplex channel usually relies on the physical isolation of the transmitter and the receiver and suitable interference elimination techniques. Full-duplex simulation is frequently implemented for wireless links by using frequency division duplex (FDD) or time division duplex (TDD). In FDD, transmissions in different directions operate at different carrier frequencies. In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, at some times, the channel is dedicated to transmission in one direction, and at other times, the channel is dedicated to transmission in another direction, wherein the direction can change very quickly (e.g., several times per time slot).

[0062] Various aspects of the present disclosure will be described with reference to OFDM waveforms. Figure 3 An example of an OFDM waveform is schematically shown in FIG. It should be understood by those skilled in the art that various aspects of the present disclosure may be applied to SC-FDMA waveforms in substantially the same manner as described below herein. That is, although some examples of the present disclosure may focus on OFDM links for clarity, it should be understood that the same principles may also be applied to SC-FDMA waveforms.

[0063] Figure 3 is a schematic diagram of wireless resources in an air interface utilizing orthogonal frequency division multiplexing (OFDM) according to some aspects of the present disclosure. Figure 3 , an expanded view of an example DL subframe (SF) 302A is shown, showing an OFDM resource grid. However, as will be readily apparent to those skilled in the art, the PHY transmission structure for any particular application may differ from the examples described herein, depending on any number of factors. Here, time is in the horizontal direction, in units of OFDM symbols, and frequency is in the vertical direction, in units of subcarriers.

[0064] Resource grid 304 can be used to schematically represent the time-frequency resources for a given antenna port. That is, in a multiple-input multiple-output (MIMO) implementation with multiple available antenna ports, corresponding multiple resource grids 304 can be available for communication. Resource grid 304 is divided into multiple resource elements (RE) 306. RE (which is 1 carrier × 1 symbol) is the smallest discrete part of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the modulation used in a specific implementation, each RF can represent one or more bits of information. In some examples, a block of REs can be referred to as a physical resource block (PRB) or more simply a resource block (RB) 308, which contains any appropriate number of consecutive subcarriers in the frequency domain. In one example, an RB can include 12 subcarriers, regardless of the number scheme used. In some examples, depending on the digital scheme, an RB can include any appropriate number of consecutive OFDM symbols in the time domain. In the present disclosure, it is assumed that a single RB (e.g., RB 308) corresponds entirely to a single communication direction (for a given device, a send or receive direction).

[0065] Scheduling of a UE (e.g., a scheduled entity) for downlink or uplink transmissions typically involves scheduling one or more resource elements 306 within one or more bandwidth parts (BWPs), where each BWP includes one or more contiguous or consecutive RBs. Thus, a UE typically utilizes only a subset of a resource grid 304. In some examples, an RB may be the smallest unit of resources that may be allocated to a UE. Thus, the more RBs scheduled for a UE, and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE.

[0066] In this illustration, RB 308 is shown as occupying less than the entire bandwidth of subframe 302A, with some subcarriers shown above and below RB 308. In a given implementation, subframe 302A may have a bandwidth corresponding to any number of one or more RBs 308. Furthermore, in this illustration, while RB 308 is shown as occupying less than the entire duration of subframe 302A, this is merely one possible example.

[0067] Each 1 ms subframe 302A may be composed of one or more adjacent time slots. Figure 3In the example shown in , a subframe 302B includes four time slots 310 as an illustrative example. In some examples, the time slot can be defined according to a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot can include 7 or 14 OFDM symbols with a nominal CP. Additional examples may include mini-slots with shorter durations (e.g., one or two OFDM symbols). In some cases, these mini-slots may be sent occupying resources scheduled for ongoing time slot transmissions for the same or different UEs.

[0068] An expanded view of one of the time slots 310 shows that the time slot 310 includes a control region 312 and a data region 314. In general, the control region 312 may carry a control channel (e.g., a PDCCH), and the data region 314 may carry a data channel (e.g., a PDSCH or a PUSCH). Of course, a time slot may contain all DL, all UL, or at least one DL portion and at least one UL portion. Figure 3 The simple structure shown in is merely exemplary in nature, and different time slot structures may be utilized and may include one or more regions in each of the control region and the data region.

[0069] Although not in Figure 3 308, but each RE 306 within the RB 308 may be scheduled to carry one or more physical channels, including a control channel, a shared channel, a data channel, etc. Other REs 306 within the RB 308 may also carry pilot or reference signals, including but not limited to a demodulation reference signal (DMRS) or a sounding reference signal (SRS). These pilot or reference signals may prepare a receiving device to perform channel estimation of the corresponding channel, which may enable coherent demodulation / detection of the control and / or data channels within the RB 308.

[0070] In a DL transmission, a transmitting device (e.g., a scheduling entity) may allocate one or more REs 306 (e.g., within a control region 312) for carrying DL control information including one or more DL control channels (e.g., PBCH; physical control format indicator channel (PCFICH); physical hybrid automatic repeat request (HARQ) indicator channel (PHICH); and / or physical downlink control channel (PDCCH), etc.) to one or more scheduled entities. The transmitting device may also allocate one or more REs 306 to carry other DL signals (e.g., DMRS; phase tracking reference signal (PT-RS); channel state information reference signal (CSI-RS); primary synchronization signal (PSS); and secondary synchronization signal (SSS)).

[0071] The synchronization signals PSS and SSS, and in some examples the PBCH and PBCH DMRS, may be sent in a synchronization signal block (SSB) comprising 3 consecutive OFDM symbols, which are numbered in increasing order from 0 to 3 via a time index. In the frequency domain, an SSB may contain more than 240 consecutive subcarriers, where the subcarriers are numbered in increasing order from 0 to 239 via a frequency index. Of course, the present disclosure is not limited to this particular SSB configuration. Other non-limiting examples within the scope of the present disclosure may utilize more than or less than two synchronization signals; may include one or more supplemental channels in addition to the PBCH; may omit the PBCH; and / or may utilize a different number of symbols and / or non-contiguous symbols for the SSB.

[0072] The PCFICH provides information for assisting a receiving device in receiving and decoding the PDCCH. The PDCCH carries downlink control information (DCI), which includes but is not limited to power control commands, scheduling information, grants, and / or assignments of REs for DL ​​and UL transmissions. The PHICH carries HARQ feedback transmissions, such as acknowledgments (ACKs) or negative acknowledgments (NACKs). HARQ is a technique well known to those skilled in the art, in which the integrity of a packet transmission can be checked for accuracy on the receiving side, for example, using any appropriate integrity check mechanism, such as a checksum or a cyclic redundancy check (CRC). If the integrity of the transmission is confirmed, an ACK can be sent, and if the integrity of the transmission is not confirmed, a NACK can be sent. In response to the NACK, the transmitting device can send a HARQ retransmission, which can achieve append merging, incremental redundancy, and the like.

[0073] In UL transmission, a transmitting device (e.g., a scheduled entity) may utilize one or more REs 306 to carry UL control information, which includes one or more UL control channels to a scheduling entity, such as a physical uplink control channel (PUCCH). The UL control information may include a variety of packet types and categories, including pilots, reference signals, and information configured to implement or assist in decoding uplink data transmissions. For example, the UL control information may include a DMRS or an SRS. In some examples, the control information may include a scheduling request (SR), i.e., a request for a scheduling entity to schedule an uplink transmission. Here, in response to the SR sent on the control channel, the scheduling entity may send downlink control information, which may schedule resources for uplink packet transmission. The UL control information may also include HARQ feedback, channel state feedback (CSF), or any other appropriate UL control information.

[0074] In addition to control information, one or more REs 306 (e.g., within the data region 314) may also be allocated for user data or traffic data. Such traffic may be carried on one or more traffic channels (e.g., PDSCH for DL ​​transmissions or physical uplink shared channels (PUSCH) for UL transmissions). In some examples, one or more REs 306 within the data region 314 may be configured to carry SIBs (e.g., SIB1) that carry information that may enable access to a given cell.

[0075] These physical channels described above are typically multiplexed and mapped to transport channels for processing at the medium access control (MAC) layer. Transport channels carry blocks of information called transport blocks (TBs). The transport block size (TBS), which may correspond to the number of bits of information, may be a controlled parameter based on the modulation and coding scheme (MCS) and the number of RBs in a given transmission.

[0076] References Figure 1-3 The channels or carriers described are not necessarily all channels or carriers that may be utilized between a scheduling entity and a scheduled entity, and those skilled in the art will recognize that other channels or carriers may be utilized in addition to those shown, such as other traffic, control, and feedback channels.

[0077] In some networks, the base station may schedule the UE using dynamic scheduling or semi-persistent scheduling (SPS). Dynamic scheduling may involve using DCI to schedule individual transmissions or receptions (e.g., on PDSCH or PUSCH). For example, the base station may use a first DCI to schedule a first PDSCH transmission, a second DCI to schedule a second PDSCH transmission, and so on.

[0078] In contrast, for SPS, a base station may use a single DCI to schedule multiple transmissions (e.g., on the PDSCH). In some implementations, the base station sends an RRC message to configure SPS (e.g., for a specific cell and a specific BWP). The base station may then send a DCI to activate SPS.

[0079] The SPS configuration indicates the SPS period between SPS opportunities. In this way, the SPS configuration can schedule multiple SPS opportunities with the indicated period. In some examples, the period can refer to the system frame number (SFN) and subframe number of the DCI that initializes the SPS.

[0080] Therefore, the UE can monitor the PDSCH at the SPS opportunity according to the scheduled SPS period to periodically obtain data from the base station. At a certain point in time, the base station can send a DCI to deactivate the SPS. In addition, the base station can send a DCI to reactivate the SPS.

[0081] In some aspects, the present disclosure relates to sending information in multiple communication opportunities in an SPS opportunity. Here, an SPS opportunity is defined as including multiple communication opportunities. For example, a given SPS opportunity may be assigned several time slots (hereinafter referred to as time slots), wherein each communication opportunity is associated with a corresponding time slot (or a corresponding subset of time slots) in the time slots. Therefore, a base station may send first information via a first communication opportunity in an SPS opportunity, and send second information via a second communication opportunity in the same SPS opportunity. A wireless communication device (e.g., UE) may perform blind decoding on all communication opportunities to recover information sent in any communication opportunity in the communication opportunity.

[0082] Figure 4 400 is a conceptual diagram of an example of multiple communication opportunities in an SPS opportunity 400 according to some aspects of the present disclosure. Three SPS opportunities are shown separated in time by a time period T, which is based on a configured SPS cycle. DL traffic is scheduled by SPS to arrive at a nominal arrival time (e.g., nominal arrival time 402).

[0083] In practice, the received data may be affected by jitter. Figure 4 The example shows a non-micro jitter around the nominal arrival time and a low latency delivery requirement (within the delivery window T V For example, the DL transmission may be received before the nominal arrival time (e.g., as shown by the actual arrival 404), received after the nominal arrival time, or partially overlap with the nominal arrival time, as shown. In multi-opportunity SPS, each SPS opportunity provides multiple communication opportunities for the UE to receive DL traffic when the base station transmits based on packet arrival within one communication opportunity (e.g., corresponding to the nominal arrival time).

[0084] like Figure 4 As shown in , in this example, each SPS opportunity is defined as having (e.g., including) three communication opportunities (e.g., as represented by three lines 406 for the third SPS opportunity). In other examples, a different number of communication opportunities may be used. The UE may be at Figure 4 The UE can decode all three communication opportunities in order to receive the DL traffic. Therefore, the UE will be able to successfully receive the traffic in any of the three communication opportunities. Therefore, multi-opportunity SPS can be used to accommodate jittery periodic DL traffic (e.g., Figure 4 ).

[0085] Multi-opportunity SPS may provide benefits compared to using multiple SPS configurations (e.g., where a base station establishes multiple SPS allocations, each SPS allocation being scheduled on different resources). For example, multi-opportunity SPS may use a smaller number of HARQ processes, use a smaller number of HARQ responses, and have lower overhead with respect to RRC configuration and DCI activation / deactivation compared to scenarios using multiple SPS configurations.

[0086] In some examples, communication opportunities within an SPS opportunity may be homogeneous in terms of radio resource allocation. For example, different communication opportunities within the same SPS opportunity may have the same frequency domain resource allocation (FDRA), the same start and length indicator vector (SLIV), and the same MCS. This approach may be advantageous when sending fixed-size packets with jittery arrivals. For example, a smaller DCI (smaller number of bits) may be used for activation / reactivation since unique information is not required for each communication opportunity.

[0087] Using homogeneous radio resource allocation for different communication opportunities within an SPS opportunity can also provide other benefits. For example, the listen-before-talk (LBT) uncertainty at the base station can be mitigated by allocating communication opportunities to different LBT bandwidths (BWs) in the 5GHz / 6GHz unlicensed band. In addition, by allocating communication opportunities with different receive (RX) beams, more flexible scheduling can be supported (e.g., frequency range 2 (FR2) can be used). In addition, time slot aggregation can be turned on on some communication opportunities to deliver ultra-reliable packets.

[0088] In some scenarios, a UE may need to carry more than one periodic flow. For example, an Industrial IoT (IIoT) UE may be connected to more than one sensor and / or actuator. In addition, the associated concurrent service flows may have different periods and / or different latency requirements.

[0089] In some aspects, the disclosure relates to sending information on multiple communication opportunities in an SPS opportunity.For example, a base station may send data on a first communication opportunity and a second communication opportunity in the same SPS opportunity.

[0090] In some aspects, the present disclosure also relates to sending information on multiple communication sub-opportunities for each SPS communication opportunity. This may be referred to as massive opportunity SPS DL.

[0091] Figure 5 is a conceptual diagram of an example of multiple communication opportunities and communication sub-opportunities in an SPS opportunity 500 according to some aspects of the present disclosure. Figure 4Similarly, in this example, each SPS opportunity is defined as having (e.g., including) three communication opportunities (e.g., as represented by three columns 502 for the third SPS opportunity). In addition, each communication opportunity is defined as having (e.g., including) two communication sub-opportunities (e.g., as represented by two rows 504 for the third SPS opportunity).

[0092] The base station may transmit on any one or more of the communication opportunities. The UE may be configured via RRC to support multi-opportunity SPS DL. The parameter s (s≥1) may specify the number of communication opportunities starting from an offset within a given period.

[0093] In some examples, one HARQ process may be used per communication opportunity. The UE may perform blind decoding of the SPS PDSCH at each communication opportunity and report s bits of ACK / NACK (A / N) feedback. Based on the A / N feedback, the base station may schedule retransmissions on a per-opportunity basis using a dynamic grant (DG).

[0094] In some examples, the base station may send one transport block (TB) per communication opportunity for "opportunistic" large-scale opportunities. In some examples, the base station may send multiple TBs per communication opportunity for large-scale opportunities. In some examples, the base station may send multiple transport blocks (TBs) on more than one communication opportunity in an SPS opportunity.

[0095] As discussed herein, the use of communication opportunities may provide lower signaling overhead compared to other techniques. However, the use of communication opportunities may result in additional overhead associated with HARQ processes per opportunity and A / N feedback per opportunity. Nevertheless, the use of communication opportunities may still have lower RRC configuration (L3) overhead and lower DCI activation / reactivation (L1) overhead compared to multiple SPS configurations requiring separate RRC messages and DCI for multiple SPS processes.

[0096] In some examples, communication opportunities (e.g., for a given SPS or for a given SPS opportunity) can be homogeneous. For example, communication opportunities can share a common TDRA, a common FDRA (for FDM, including different component carriers), antenna ports and / or transmission configuration indicators (TCI) (for space division multiplexing (SDM)), or a combination thereof.

[0097] In some examples, the communication opportunities may be heterogeneous. Using heterogeneous communication opportunities may involve using more bits in the activation / reactivation DCI than in a homogeneous scenario. However, the L3 and L1 signaling overheads may still be lower than those required for multiple SPS configurations.

[0098] Figure 6 1 is a conceptual diagram of an example of a hybrid automatic repeat request (HARQ) process for multiple communication opportunities in an SPS opportunity according to some aspects of the present disclosure. Different HARQ processes (HARQ 0, HARQ 1, and HARQ 2) are used for different communication opportunities. In this example, all communication opportunities are configured / activated with the same number of radio resources for homogeneous initial transmissions. That is, the communication opportunities are only shifted in time. In addition, the UE uses a single PUCCH to send s bits of A / N feedback.

[0099] In this example, the base station sends data via a first communication opportunity (opportunity 1) and a third communication opportunity (opportunity 3). The second communication opportunity is a discontinuous transmission (DTX). Since the UE is able to decode the first communication opportunity but not the second and third communication opportunities, the UE sends corresponding (A / N) feedback in PUCCH 602, such as Figure 6 As shown. In response, the base station schedules retransmission for the third communication opportunity. Specifically, the base station sends DCI 604, which schedules retransmission for HARQ2 in PDSCH 606.

[0100] Figure 6 The multi-opportunity SPS can be activated / deactivated through a compact-sized DCI. Figure 7 702 is a conceptual diagram of an example of multiple communication opportunities in a DCI activation / reactivation SPS opportunity according to some aspects of the present disclosure. In this example, the SLIV applies to all s time slots starting from the time slot indicated by K0 in the SPS activation DCI 702 (i.e., all communication opportunities use the same SLIV). In addition, in this example, the communication opportunities use the same FDRA, the same MCS, and the same TCI. The indicated K1 timing can be relative to the first communication opportunity (such as Figure 7 ) or the last communication opportunity.

[0101] Figure 8 800 is a conceptual diagram of an example of HARQ feedback and HARQ retransmission scheduling for multiple communication opportunities in an SPS opportunity according to some aspects of the present disclosure. After receiving multiple NACKs, the base station can use composite DCI 802 to schedule multiple PDSCH retransmissions. To reduce overhead, the composite DCI 802 can have a single CRC, a common MCS (e.g., because the retransmissions are toward the same UE), a common FDRA, a common TCI, and / or the same SLIV in different time slots.

[0102] The DCI 802 may include incremental HARQ process ID wrapping within the HARQ process ID space of the SPS. The DCI 802 may include a new data indicator (NDI) to indicate which communication opportunity was retransmitted due to consecutive HARQ ID restrictions. This may assume a preconfigured redundant vector (RV) sequence. Figure 8 In the example of , 4 bits (eg, 2 bits for HARQ process ID=0 and 2 bits for NDI-based retransmission indication for the remaining HARQ processes) may be used to indicate retransmissions for HARQ 0 and HARQ2.

[0103] As Figure 8 As an alternative to the homogeneous approach, SPS may have heterogeneous (with respect to radio resource allocation) communication opportunities within an SPS opportunity. Fig. 9 is a conceptual diagram of an example of a HARQ process (in this example, HARQ0) for a multi-slot communication opportunity covering an SPS opportunity according to some aspects of the present disclosure. Specifically, Fig. 9 The first communication opportunity is shown to support time slot aggregation over two time slots. Time slot aggregation over more than two time slots may also be used.

[0104] exist Fig. 9 In the example of , retransmission DGs for the same HARQ ID (e.g., in DCI 902) may apply the same level of slot aggregation. Other examples of heterogeneous operation include using different MCSs or using different SLIVs or using both. In some aspects, heterogeneous operation may involve using a larger DCI for activation / reactivation (e.g., to specify different parameters for different communication opportunities).

[0105] NR operation in an unlicensed band may be referred to as NR-U. For NR-U UEs with reduced capability operating BW ≤ 20 MHz and served by wideband (e.g., 80 MHz BW) base stations, the communication opportunities in SPS opportunities may be heterogeneous with respect to the transmission band. Listen-before-talk (LBT) ambiguity at the base station may be mitigated by using different LBT bandwidths for communication opportunities. The FDRA (e.g., band) of the corresponding communication opportunity may be set / reset via DCI activation / reactivation. Fig.10 1004 is a conceptual diagram of an example of transmitting different communication opportunities in SPS opportunities via different radio frequency (RF) bands according to some aspects of the present disclosure. In this example, the base station transmits communication opportunity 1 1002 in one RF band and transmits communication opportunity 3 1004 in another RF band. Thus, for different communication opportunities, the UE can monitor different RF bands.

[0106] For UEs in FR2 (or some other mmW band), the communication opportunities in an SPS opportunity may be heterogeneous in the spatial domain (e.g., the UE may tune to different beams transmitted by the base station). The beam to be used may be set / reset via DCI activation / reactivation. Fig.11 1 is a conceptual diagram of an example of transmitting different communication opportunities in an SPS opportunity via different RF beams according to some aspects of the present disclosure. In this example, the base station transmits communication opportunity 1 via one RF beam 1102 and transmits communication opportunity 3 via another RF beam 1104. Thus, for different communication opportunities, the UE can monitor different spatial domains.

[0107] As discussed above, in some aspects, the present disclosure relates to the use of communication sub-opportunities. For example, t (t ≥ 1) sub-opportunities may be defined for each communication opportunity. Among the t communication sub-opportunities, in some examples, the base station may choose to transmit on one of the sub-opportunities of each communication opportunity. In other examples, the base station may choose to transmit on more than one of the sub-opportunities of each communication opportunity. For each communication opportunity, the UE may perform blind decoding at each sub-opportunity. In some examples, the UE may select the sub-opportunity with the greatest probability of PDSCH decoding for HARQ combination.

[0108] By using communication sub-opportunities, the UE can be configured with massive opportunity DL SPS. The base station can send TBs on any sub-opportunity (not limited to one). One HARQ process can be used for each sub-opportunity. The UE can report s*t A / Ns for each SPS opportunity.

[0109] The above communication sub-opportunities can be allocated to have different FDRAs. This can be used for frequency domain diversity (including different component carriers (CCs)). For example, different communication sub-opportunities can be used at different LBT bandwidths to mitigate LBT uncertainties in unlicensed bands. DCI can be sent on a CC to activate / reactivate communication sub-opportunities in other CCs. The communication sub-opportunities discussed herein can be allocated to different beams (e.g., by using different antenna ports or different TCIs). The communication sub-opportunities discussed herein are allocated to different FDRAs and different beams.

[0110] Fig.12 1 is a signaling diagram illustrating SPS communication 1200 in a wireless communication network including UE 1202 and BS 1204. In some examples, UE 1201 may correspond to Figure 1 The scheduled entity 126 (eg, UE, etc.), or Figure 2In some examples, BS 1204 may correspond to one or more of UEs 222, 224, 226, 228, 230, 232, 234, 238, 240, or 242. Figure 1 The scheduling entity 128, or Figure 2 One or more of base stations 210, 212, 214 or 216.

[0111] exist Fig.12 At step 1206, BS 1204 configures the SPS. In some examples, the SPS configuration may specify that each SPS opportunity includes multiple communication opportunities.

[0112] At step 1208, BS 1204 sends an RRC message including the SPS configuration.

[0113] At step 1210, BS 1204 activates the SPS.

[0114] At step 1212, BS 1204 sends a DCI indicating that the configured SPS is being activated to UE 1202. In some examples, the DCI may specify that data may be sent in multiple communication opportunities in the SPS opportunity.

[0115] At step 1214, BS 1204 generates DL data for a first SPS opportunity including a plurality of communication opportunities.

[0116] At step 1216, BS 1204 transmits a first SPS opportunity. The first SPS opportunity includes data in a plurality of communication opportunities (eg, as discussed herein).

[0117] At step 1218, the UE 1202 decodes the first SPS opportunity and determines whether each communication opportunity is successfully decoded. For example, the UE 1032 may perform a separate HARQ process for each communication opportunity.

[0118] At step 1220, the UE 1202 sends a PUCCH message including a corresponding acknowledgement (eg, a positive acknowledgement (ACK) or a negative acknowledgement (NACK)) for each communication opportunity.

[0119] At step 1222, if the PUCCH includes any NACKs, the BS 1204 schedules a retransmission for each corresponding communication opportunity.

[0120] At step 1224, BS 1204 sends a DCI scheduling a corresponding retransmission for each NACKed communication opportunity, if applicable.

[0121] At step 1226, BS 1204 sends each scheduled retransmission (eg, on the PDSCH), if applicable.

[0122] At step 1228, the UE 1202 receives and decodes each scheduled retransmission (eg, on the PDSCH), if applicable. If the UE 1202 does not successfully decode all communication opportunities that include data, the above HARQ process may be repeated as needed.

[0123] At step 1230, the BS 1204 generates DL data for a second SPS opportunity including a plurality of communication opportunities.

[0124] At step 1232, BS 1204 sends a second SPS opportunity. The second SPS opportunity includes data in multiple communication opportunities (e.g., as discussed herein). As represented by line 1234, BS 1204 sends the second SPS opportunity (relative to the first SPS opportunity) according to the SPS period specified by the SPS configuration.

[0125] At step 1236, the UE 1202 decodes the second SPS opportunity and determines whether each communication opportunity is successfully decoded. Again, the UE 1032 may perform a separate HARQ process for each communication opportunity.

[0126] At step 1238, the UE 1202 sends a PUCCH message including a corresponding acknowledgement (eg, ACK or NACK) for each communication opportunity.

[0127] Fig.13 1 is a diagram illustrating an example of a hardware implementation for a wireless communication device 1300 employing a processing system 1314. For example, the wireless communication device 1300 may be a user equipment (UE) or other device configured to wirelessly communicate with a base station, such as in Figure 1-12 According to various aspects of the present disclosure, a processing system 1314 including one or more processors 1304 may be used to implement an element, or any portion of an element, or any combination of elements. In some implementations, the wireless communication device 1300 may correspond to Figure 1 The scheduled entity 106 (eg, UE, etc.) Figure 2 UE 222, 224, 226, 228, 230, 232, 234, 238, 240 or 242, or Fig.12 One or more of the UEs 1202 in .

[0128] The wireless communication device 1300 may be implemented using a processing system 1314 including one or more processors 1304. Examples of the processor 1304 include a microprocessor, a microcontroller, a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gated logic, a discrete hardware circuit, and other suitable hardware configured to perform the various functions described throughout the present disclosure. In various examples, the wireless communication device 1300 may be configured to perform any one or more of the functions described herein. That is, the processor 1304 as utilized in the wireless communication device 1300 may be used to implement any one or more of the processes or flows described below.

[0129] In this example, the processing system 1314 can be implemented using a bus architecture, which is generally represented by bus 1302. Depending on the specific application and overall design constraints of the processing system 1314, the bus 1302 may include any number of interconnecting buses and bridges. The bus 1302 communicatively couples various circuits including one or more processors (which are generally represented by processor 1304), memory 1305, and computer readable media (which are generally represented by computer readable media 1306). The bus 1302 may also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further. The bus interface 1308 provides an interface between the bus 1302 and the transceiver 1310 and between the bus 1302 and the interface 1330. The transceiver 1310 provides a communication interface or unit for communicating with various other devices over a wireless transmission medium. In some examples, the wireless communication device may include two or more transceivers 1310, each transceiver being configured to communicate with a corresponding network type (e.g., terrestrial or non-terrestrial). The interface 1330 provides a communication interface or unit for communicating with various other devices and equipment (e.g., other devices or other external devices contained in the same device as the wireless communication device) via an internal bus or an external transmission medium (e.g., an Ethernet cable). Depending on the nature of the device, the interface 1330 may include a user interface (e.g., a keypad, a display, a speaker, a microphone, a joystick). Of course, such a user interface is optional and may be omitted in some examples (e.g., IoT devices).

[0132] Computer readable medium 1306 may be a non-transitory computer readable medium. For example, non-transitory computer readable media include magnetic storage devices (e.g., hard disks, floppy disks, tapes), optical disks (e.g., compact disks (CDs) or digital versatile disks (DVDs)), smart cards, flash memory devices (e.g., cards, sticks or key drives), random access memory (RAM), read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. Computer readable medium 1306 may be located in processing system 1314, outside processing system 1314, or distributed across multiple entities including processing system 1314. Computer readable medium 1306 may be embodied in a computer program product. For example, a computer program product may include a computer readable medium having packaging materials.
