[0003] This patent application claims priority to the following applications: U.S. Patent Application No. 16 / 507,282, filed July 10, 2019, entitled “RATE MATCHING AND SEMIPERSISTENT SCHEDULING CONFIGURATION IN WIRELESS COMMUNICATIONS”, by RICO ALVARINO et al.; and U.S. Provisional Patent Application No. 62 / 697,726, filed July 13, 2018, entitled “RATEMATCHING AND SEMI PERSISTENT SCHEDULING CONFIGURATION IN WIRELESS COMMUNICATIONS”, each of which is assigned to the assignee of this application. Technical Field

[0004] This disclosure relates to wireless communications, and more specifically, to rate matching and semi-persistent scheduling configurations in wireless communications. Background Technology

[0005] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A specialist systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)) simultaneously.

[0006] In some cases, wireless communication systems can use different modulation schemes for wireless transmission, such as, for example, Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (QAM), or 64QAM. Higher modulation orders can be achieved when channel conditions are relatively good, while lower modulation orders can be achieved when channel conditions are relatively poor. Different coding schemes can be combined with different modulation schemes to improve the probability of successful reception of the transmission. In some cases, the UE can measure the channel conditions and provide a Channel Quality Indication (CQI) report to the base station, which can use the CQI report to select a modulation and coding scheme (MCS) for subsequent communication with the UE. Furthermore, in some systems, signaling indicating the modulation order can also be used to provide other information (e.g., certain patterns of one or more bits in the MCS transmission can be used to confirm the activation of a semi-persistent scheduling (SPS) configuration at the UE). Enhanced flexibility in selecting the modulation order and indicating the selected modulation order to the UE can help improve the efficiency of wireless communication systems. Summary of the Invention

[0007] The described techniques relate to improved methods, systems, devices, and apparatuses supporting rate matching and semi-persistent scheduling configurations in wireless communications. Various described techniques provide methods for identifying modulation and coding schemes (MCSs) independent of a Channel Quality Indicator (CQI) table configured at the User Equipment (UE). Rate matching parameters can be determined based on one or more items in the MCS or CQI table, which can be used to determine the size of a soft buffer for storing received transmissions for decoding. In some cases, the base station can indicate the MCS via an MCS field in control information, which provides an index to the MCS table. In some cases, the MCS field can be a six-bit field and can indicate an MCS exceeding the highest MCS associated with the CQI table.

[0008] In some cases, the base station can provide the UE with a semi-persistent scheduling (SPS) configuration that allocates certain semi-persistent radio resources for recurring transmissions (e.g., voice call transmissions) without requiring separate resource allocations for each transmission. The base station can activate the SPS configuration at the UE via an activation command, and the UE can verify SPS activation based on information from several different fields of the control information, which may include the MCS field. When the MCS field is a six-bit field, the two most significant bits (MSBs) in the MCS field can be set to predetermined values ​​(e.g., both bits are set to zero) to verify SPS activation (in combination with predetermined values ​​from one or more other fields). When the MCS field indicates SPS activation, a first interpretation can be used to decode the MCS field, while a second interpretation can be used when SPS is not activated. In some cases, the first interpretation can transmit an MCS up to 64 QAM, and the second interpretation can transmit an MCS exceeding 256 QAM.

[0054] Various aspects of this disclosure provide methods for determining one or more CQI, MCS, rate matching, or semi-persistent scheduling (SPS) parameters based on a configured Channel Quality Indicator (CQI) or Modulation and Coding Scheme (MCS) table and the indicated MCS. In some cases, the modulation order indicated by the MCS may be independent of the CQI table and exceed the maximum modulation order associated with the CQI table. Rate matching parameters may be determined based on one or more items in the MCS or CQI table, and these parameters may be used to determine the size of the soft buffer used to store received transmissions for decoding. In some cases, the base station may indicate the MCS by providing an MCS field in the control information that is an index to the MCS table. In some cases, the MCS field may be a six-bit field and may indicate an MCS up to 1024QAM.

[0055] In some cases, the base station can provide SPS configuration to the UE, and the SPS configuration can be activated at the UE via an activation command. The UE can verify that SPS is activated based on information in several different fields of the control information, which may include the MCS field. When the MCS field is a six-bit field, the two most significant bits (MSBs) in the MCS field can be set to predetermined values ​​(e.g., both bits are set to zero) to verify SPS activation (in combination with predetermined values ​​of one or more other fields). When the MCS field indicates SPS activation, a first interpretation can be used to decode the MCS field, while a second interpretation can be used when SPS is not activated. In some cases, the first interpretation can signal an MCS up to 64QAM, and the second interpretation can signal an MCS exceeding 256QAM.

[0056] Such a technique can provide enhanced flexibility for the UE and base station to: identify the CQI table at the UE (which may have an associated set of modulation orders), and signal an MCS that can have a modulation order different from the one associated with the CQI table. In this case, the modulation order can be changed based on the channel conditions at the UE without reconfiguring established connections with different CQI tables. In some cases, additional flexibility can be provided by an MCS table with 64 entries indexed by a six-bit MCS field that can be signaled by the base station. In some conventional LTE systems, a 32-entry MCS table can be used, and therefore a 64-entry table can provide additional options that can be selected based on the dynamic channel conditions of the UE, and in some cases, these additional options have selectable values ​​up to 1024QAM when the UE has appropriate channel conditions.

[0057] Various aspects of this disclosure are first described in the context of an example of a wireless communication system and MCS tables and fields. These aspects are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to rate matching and semi-persistent scheduling configurations in wireless communication.

In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A specialist network, or a New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices. In some cases, the UE 115 and base station 105 may support relatively high modulation orders (e.g., modulation orders up to 1024QAM), which may be indicated via an MCS indication independent of the CQI table configured at the UE 115.

[0059] Base station 105 can wirelessly communicate with UE 115 via one or more base station antennas. Base station 105 described herein may include, or may be referred to by those skilled in the art as, a base transceiver, wireless base station, access point, wireless transceiver, Node B, evolved Node B (eNB), next-generation Node B, or gigabit Node B (any of which may be referred to as gNB), home Node B, home evolved Node B, or some other suitable term. Wireless communication system 100 may include different types of base station 105 (e.g., macro cell base station or small cell base station). UE 115 described herein can be able to communicate with various types of base station 105 and network devices (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0060] Each base station 105 may be associated with a specific geographic coverage area 110 in which communication with each UE 115 is supported. Each base station 105 may provide communication coverage to the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 may include: an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. The downlink transmission may also be referred to as a forward link transmission, and the uplink transmission may also be referred to as a reverse link transmission.

[0061] The geographic coverage area 110 for base station 105 can be divided into sectors that constitute only a part of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for macro cells, small cells, hotspots, or other types of cells, or various combinations thereof. In some examples, base station 105 can be mobile, and therefore, communication coverage is provided for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and overlapping geographic coverage areas 110 associated with different technologies can be supported by the same base station 105 or different base stations 105. The wireless communication system 100 can include, for example, heterogeneous LTE / LTE-A / LTE-A professional or NR networks, wherein different types of base stations 105 provide coverage for individual geographic coverage areas 110.

[0062] The term "cell" refers to a logical communication entity used for communication with base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)) used to distinguish adjacent cells operating via the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., Machine-Type Communication (MTC), Narrowband Internet of Things (NB-IoT), Enhanced Mobile Broadband (eMBB), or other protocol types) that can provide access for different types of devices. In some cases, the term "cell" may refer to a portion (e.g., a sector) of the geographical coverage area 110 on which the logical entity operates.

[0063] UE 115 may be distributed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile device, wireless device, remote device, handheld device, or user equipment, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client. UE 115 may also be a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or MTC device, which may be implemented in various items such as appliances, vehicles, instruments, etc.

[0064] Some UE 115s (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay that information to a central server or application that can utilize the information or present it to humans interacting with the program or application. Some UE 115s can be designed to collect information or enable automated machine behavior. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0065] In some cases, UE 115 may also be able to communicate directly with other UE 115s (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UE 115s in a group utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some cases, multiple groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some cases, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0066] Base station 105 can communicate with core network 130 and with each other. For example, base station 105 can interface with core network 130 via backhaul link 132 (e.g., via S1, N2, N3 or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) on backhaul link 134 (e.g., via X2, Xn or other interfaces).

[0067] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME can manage non-access stratum (e.g., control plane) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with the EPC. User IP packets can be transmitted through the S-GW, which itself may be connected to the P-GW. The P-GW can provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched (PS) streaming services.

[0068] At least some of the network devices (such as base station 105) may include sub-components such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with UE 115 through several other access network transport entities (which may be referred to as radio headends, smart radio headends, or transmit / receive points (TRPs)). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio headends and access network controllers) or incorporated into a single network device (e.g., base station 105).

[0069] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features. However, the waves may be sufficient to penetrate structures for macrocell service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum, such as the High Frequency (HF) or Very High Frequency (VHF), UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0070] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band). The SHF region includes frequency bands such as the 5 GHz industrial, scientific, and medical (ISM) band, which can be used opportunistically by devices capable of tolerating interference from other users.

[0071] The wireless communication system 100 can also operate in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115. However, compared to SHF or UHF transmissions, EHF transmissions may suffer even greater atmospheric attenuation and shorter distances. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions can vary depending on the country or regulatory authority.

[0072] In some cases, wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz ISM band). When operating in unlicensed radio frequency spectrum bands, wireless devices (such as base station 105 and UE 115) may employ a Listen-After-Talk (LBT) procedure before transmitting data to ensure that the frequency channel is idle. In some cases, operation in unlicensed frequency bands may be based on a CA configuration that combines CC operation in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum may include downlink transmission, uplink transmission, peer-to-peer transmission, or a combination of these. Duplexing in unlicensed spectrum may be based on Frequency Division Duplex (FDD), Time Division Duplex (TDD), or a combination of both.

[0073] In some examples, base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., base station 105) and a receiving device (e.g., UE 115), wherein the transmitting device is equipped with multiple antennas, and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers (this may be referred to as spatial multiplexing). For example, the transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, the receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0074] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to form or guide an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that signals propagating relative to a specific orientation of the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying certain amplitude and phase offsets to the signals carried by each antenna element in the antenna array associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0075] In some cases, the antennas of base station 105 or UE 115 may be located within one or more antenna arrays that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have antenna arrays with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations.

[0076] In some cases, the wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. In some cases, the Radio Link Control (RLC) layer may perform packet fragmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may also use Hybrid Automatic Repeat Request (HARQ) to provide retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical (PHY) layer, transport channels may be mapped to physical channels.

[0077] In some cases, UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. HARQ feedback is a technique to increase the likelihood of correct data reception on communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., signal and noise conditions). In some cases, the radio device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0078] Time intervals in LTE or NR can be represented as multiples of a basic time unit (e.g., a sampling period of Ts = 1 / 30,720,000 seconds). Time intervals of communication resources can be organized based on radio frames, each with a duration of 10 milliseconds (ms), where the frame period can be expressed as Tf = 307,200Ts. Radio frames can be identified by System Frame Numbers (SFNs) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 ms. Subframes can be further divided into two time slots, each with a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the smallest scheduling unit of a wireless communication system 100 and can be referred to as a Transmission Time Interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of shortened TTI (sTTI) or in a component carrier selected using sTTI).

[0079] In some wireless communication systems, time slots can be further divided into multiple micro-time slots containing one or more symbols. In some instances, the symbol or micro-time slot of a micro-time slot can be the smallest scheduling unit. For example, the duration of each symbol can vary depending on the subcarrier spacing or the frequency band of operation. Furthermore, some wireless communication systems can implement time slot aggregation, where multiple time slots or micro-time slots are aggregated together and used for communication between UE 115 and base station 105.

[0080] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication on communication link 125. For example, a carrier of communication link 125 may include a portion of a radio frequency spectrum band that operates according to physical layer channels for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an E-UTRA absolute radio frequency channel number (EARFCN)) and can be located according to a channel grid for discovery by UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode). In some examples, the signal waveform transmitted on a carrier may consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as OFDM or DFT-s-OFDM).

[0081] The carrier organization structure can vary depending on the radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR, etc.). For example, communication on a carrier can be organized according to a Time Interval (TTI) or time slot, each of which can include user data and control information or signaling to support the decoding of the user data. A carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information) and control signaling to coordinate operations on the carrier. In some examples (e.g., in a carrier aggregation configuration), a carrier can also have acquisition signaling or control signaling to coordinate operations on other carriers.

[0082] Physical channels can be multiplexed on a carrier using various techniques. For example, time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. In some examples, control information transmitted in the physical control channel can be distributed in a concatenated manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

[0083] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of several predetermined bandwidths for a carrier specific to a wireless access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 can be configured to operate on a portion or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range within the carrier (e.g., a set of subcarriers or RBs) (e.g., “in-band” deployment of a narrowband protocol type).

[0084] In systems employing MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. In MIMO systems, wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers can further increase the data rate used for communication with UE 115.

[0085] In some cases, base station 105 and UE 115 can establish a connection and, as part of the connection establishment, identify a CQI table. The CQI table may contain a mapping between the CQI measured at UE 115 and the modulation order and coding rate. After the connection is established, base station 105 may allocate resources for downlink transmissions (e.g., Physical Downlink Shared Channel (PDSCH) transmissions) and provide the UE with downlink control information (DCI) indicating the allocated resources and the MCS associated with the transmission. In some cases, the modulation order indicated by the MCS may be independent of the CQI table and exceed the maximum modulation order associated with the CQI table. UE 115 may determine rate matching parameters based on one or more items in the MCS or CQI table, which can be used to determine the size of the soft buffer used to store received transmissions for decoding. In some cases, base station 105 may indicate the MCS via the MCS field in the DCI, which provides an index to the MCS table. In some cases, the MCS field can be a six-bit field and can indicate an MCS of up to 1024 QAM.

[0086] In some cases, base station 105 can provide SPS configuration to UE 115, and the SPS configuration can be activated at UE 115 via an activation command. UE 115 can verify SPS activation based on the values ​​of several different fields of the DCI (which may include the MCS field). When the MCS field is a six-bit field, two MSBs in the MCS field can be set to predetermined values ​​(e.g., both bits are set to zero) to verify SPS activation (in combination with predetermined values ​​of one or more other fields). When the MCS field indicates SPS activation, a first interpretation can be used to decode the MCS field, while a second interpretation can be used when SPS is not activated. In some cases, the first interpretation can signal an MCS up to 64QAM, and the second interpretation can signal an MCS exceeding 256QAM.

[0087] Figure 2 Examples of a portion of a wireless communication system 200 supporting rate matching and semi-persistent scheduling configurations in wireless communication are shown according to various aspects of this disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may include a base station 105-a and a UE 115-a, which may be referenced... Figure 1Examples of base station 105 and UE 115 are described. In some examples, base station 105-a can communicate with one or more UEs 115 within a geographic coverage area 110-a. In this example, wireless communication system 200 can support communication link 205 with a relatively high modulation order (such as 256QAM or 1024QAM), and control information 210 can provide a six-bit MCS field that provides an index to a 64-entry MCS table.

[0088] In some cases, as part of connection establishment for establishing communication link 205, UE 115-a can provide CQI reports, and base station 105-a can configure a CQI table to be used at UE 115-a. The CQI table can map modulation order and coding rate to several (e.g., 16) index values ​​based on CQI values ​​measured at UE 115-a. In some conventional LTE or NR systems, the MCS indicated in the DCI is linked to the modulation order in the CQI table, and therefore, the MCS and CQI table transmitted with the signal can be used by UE 115-a to determine the modulation order, coding rate, and transport block size for transmission. Furthermore, UE 115-a can perform rate matching on received downlink transmissions and place transport blocks in a soft buffer for decoding. In such cases, rate matching can be based on a configured CQI table, where UE 115-a configures its soft buffer size according to the MCS and coding rate. For example, in some cases, UE 115-a can be based on the value (K) associated with the configured CQI table. C (For example, according to 3GPP TS 36.212, section 5.1.4) determine the number of bits (N) used for a transport block. IR ) and the size of the soft buffer for a specific code block (N) cb In some cases, N IR It is obtained according to the following equation:

[0089]

[0090] And size N cb It is obtained according to the following equation:

[0091]

[0092] Where, N soft It is the total number of soft channel bits based on the UE category; K MIMO The transmission mode based on the UE is either equal to one or equal to two; M DL_HARQ This is the maximum number of DL HARQ processes; M limit It is a constant equal to 8; K wK is the total number of coded bits, and C is the number of code blocks. As noted, K can be predetermined based on the CQI table configured at UE 115-a. C The value of K. For example, in some cases (e.g., according to 3GPP TS 36.212), K can be determined as follows: C Value:

[0093] If the UE is configured by a higher layer to have altCQI-Table-1024QAM-r15

[0094] Then K C =8 / 5

[0095] Otherwise, if the UE is configured by a higher layer to have altCQI-Table-r12,

[0096] Then K C =2

[0097] otherwise

[0098] K C =8 / 3.

[0099] However, in some deployments, the modulation order of the signaled MCS may be independent of the CQI table, and in some cases, the signaled MCS may exceed the maximum modulation order associated with the CQI table. In such cases, UE 115-a can use one or more other techniques to determine rate matching and soft buffer size. In some examples, when UE 115-a is configured to have a six-bit MCS field in control information 210, base station 105-a may have a constraint that UE 115-a is not scheduled to utilize a modulation order exceeding the highest modulation order of the configured CQI table. Therefore, UE 115-a may expect to receive such an MCS and may discard or ignore DCI transmissions from base station 105-a indicating a higher MCS. For example, if UE 115-a is configured with a 256QAM CQI table (where the highest modulation order associated with the CQI table is 256QAM), then UE 115-a is not expected to be scheduled to utilize 1024QAM, and base station 105-a will schedule 256QAM or a lower modulation order. Similarly, if UE 115-a is configured with a 64QAM CQI table, then UE 115-a is not expected to be scheduled to utilize either 256QAM or 1024QAM. Furthermore, in some cases, UE 115-a can set the power level of the receiver RF circuitry based on the CQI table, and if a lower modulation order is configured in the CQI table, UE 115-a may be able to reduce the power level of the RF circuitry. In such an example, the rate matching behavior at UE 115-a therefore follows the configured CQI table. In some other examples, when the MCS indicates a modulation order exceeding the highest modulation order of the configured CQI table, the UE115-a can reinterpret the MCS transmitted by the signal and move to the highest MCS with a supported modulation scheme.

[0100] In some other examples, when UE 115-a is configured with a six-bit MCS field, the rate matching behavior can be set to the maximum supported modulation scheme in the frequency bands of the carrier band combination to be used for transmission. For example, if UE 115-a is configured with a 256QAM CQI table, but UE 115-a supports 1024QAM in the carrier bands of the frequency band combination, then UE 115-a can perform rate matching under the assumption of 1024QAM. In some examples employing this technique, K can be determined as follows: C Value:

[0101] If the UE is configured by a higher layer to have altCQI-Table-1024QAM-r15, or if the UE is configured by a higher layer to have altMCS-Table and the UE indicates support for 1024QAM in the frequency bands of the frequency band combination, then

[0102] K C =8 / 5

[0103] Otherwise, if the UE is configured by a higher layer to have altCQI-Table-r12, or if the UE is configured by a higher layer to have altMCS-Table and the UE indicates (in the bands of the band combination) support for 256QAM, then

[0104] K C =2

[0105] otherwise,

[0106] K C =8 / 3.

[0107] In some other examples, base station 105-a can explicitly transmit a reference modulation scheme to be used for rate matching (e.g., via individual parameters configured for each component carrier). For example, such a case could allow base station 105-a to implement a six-bit MCS field instead of 1024QAM (e.g., without understanding the capability for 1024QAM). In some examples employing this technique, K can be determined as follows: C Value:

[0108] If the UE is configured by a higher layer to have altCQI-Table-1024QAM-r15, or if the UE is configured by a higher layer to have altMCS-Table and altMCS-Table-

[0109] referenceModulation=1024QAM, then

[0110] K C =8 / 5

[0111] Otherwise, if the UE is configured by a higher layer to have altCQI-Table-r12, or if the UE is configured by a higher layer to have altMCS-Table and altMCS-Table-

[0112] referenceModulation=256QAM, then

[0113] K C =2

[0114] otherwise,

[0115] K C =8 / 3.

[0116] In another example, base station 105-a can provide a constraint on the maximum scheduled transport block size rather than the modulation scheme. This technique discriminates that for small transport block size values, the rate matching behavior is the same regardless of the modulation scheme (i.e., since when determining N...). cb The minimum operator used at that time is as described above. In such an example, the maximum transport block size can be identified as follows:

[0117] Maximum transport block size for 64-QAM: 75376;

[0118] Maximum transport block size for 256-QAM: 100752;

[0119] Maximum transport block size for 1024-QAM: 125808.

[0120] Therefore, for transport block sizes mapped to a single layer, if UE 115-a is configured with a CQI table for 64QAM, it is likely undesirable for the UE to receive transport block sizes greater than 75376, and if UE 115-a is configured with a CQI table for 256QAM, it is likely undesirable for the UE 115-a to receive transport block sizes greater than 100752. Similar maximum transport block sizes can be identified when transport block sizes are mapped to multiple layers.

[0121] In another example, UE 115-a can perform rate matching by following the MCS and modulation scheme (which follows a configuration with a specific CQI table) transmitted from base station 105-a for the first transmission. In some examples employing this technique, K can be determined as follows: C Value:

[0122] If the UE is configured by a higher layer to have altCQI-Table-1024QAM-r15, or if the UE is configured by a higher layer to have altMCS-Table and the first transmission of the transport block size uses 1024QAM, then

[0123] K C =8 / 5

[0124] Otherwise, if the UE is configured by a higher layer to have altCQI-Table-r12, or if the UE is configured by a higher layer to have altMCS-Table and the first transmission of the transport block size uses 256QAM, then

[0125] K C=2

[0126] otherwise,

[0127] K C =8 / 3.

[0128] Therefore, base station 105-a and UE 115-a, when configured with a six-bit MCS field, can use such techniques to determine the rate matching parameters for transmission. Additionally, in some cases, UE 115-a may have the ability to adjust RF power settings. For example, UE 115-a may have the ability to place its RF front-end in a "low-fidelity" mode to achieve power savings, which can reduce the maximum modulation scheme that UE 115-a can support. In some cases, UE 115-a may choose to operate in this "low-fidelity mode" (e.g., based on previous transmissions of base station 105-a, power consumption, available battery capacity, thermal limits, one or more other parameters, or a combination thereof), and if permission is received to have a modulation order higher than desired, UE 115-a may be unable to decode. In the case where the UE selects to operate in "high-fidelity mode," it may receive higher modulation order transmissions, but this may consume unnecessary power if base station 105-a does not schedule higher modulation order transmissions. In some cases, UE 115-a may send a capability indication to base station 105-a, indicating whether UE 115-a expects to receive higher modulation order transmissions. In some cases, the capability indication may indicate whether UE 115-a supports receiving modulation orders higher than those in the configured CQI table. In some cases, in response to the capability indication, base station 105-a may provide configuration to UE 115-a indicating whether to monitor and / or expect modulation orders higher than those in the configured CQI table.

[0129] Figure 3 Examples of an MCS table 300 supporting rate matching and semi-persistent scheduling configurations in wireless communications are shown according to various aspects of this disclosure. In some examples, the MCS table 300 may be implemented in various aspects of a wireless communication system 100 or 200. As described above, in some cases, a six-bit MCS field may be used to indicate the MCS to the UE, wherein the value of the six-bit field corresponds to an MCS index 305 for a 64-entry MCS table 300. The MCS table 300 may include columns for a first modulation order Qm 310, columns for a second modulation order Q'm 315 used by the UE for scheduling in a single time slot of a subframe, a transport block size index column 320, and a scaling column 325.

[0130] In this example, line 335 corresponds to the entry where scaling is set to "Yes" (indicating that a scaling value is applied to account for overhead). In some examples, for entries where "Scaling = No", the UE follows the conventional procedure to determine the transport block size, while for entries where "Scaling = Yes" (i.e., the entries in lines 335-a and 335-b), the UE can select the transport block size by scaling the number of allocated PRBs by a factor α, where α is configured by the RRC. Entry 330 in this example is a reserved entry for retransmission.

[0131] Figure 4 Examples of a six-bit MCS field 400 supporting rate matching and semi-persistent scheduling configurations in wireless communications are shown according to various aspects of this disclosure. In some examples, the six-bit MCS field 400 may be implemented in various aspects of wireless communication systems 100 or 200. In this example, the six-bit MCS field 405 may be used to indicate an index value to an MCS table (e.g., MCS table 300). In some cases, as noted above, the UE may be configured with an SPS configuration, and in such cases, the MCS field 410 may be scrambled by a different identifier used to indicate that the DCI is for SPS. For example, the MCS field 405 may be scrambled by a Cell Radio Network Temporary Identifier (C-RNTI), and the MCS field 410 may be scrambled by a separate SPS C-RNTI. In this example, the two most significant bits 315 of the MCS field 410 may be set to predetermined values ​​(e.g., 0, 0) to indicate that SPS is activated at the UE. In some cases, for a DCI scrambled using SPS C-RNTI, and if the DCI has a six-bit field for the MCS, the UE may interpret the MCS field 410 as mapped to a five-bit 64QAM MCS table (32 entries) if one or more of the following constraints apply: 1) both MSBs 415 of the MCS field 410 are set to zero, or 2) retransmission of the MCS is prohibited (i.e., the MCS between 29 and 31 of the five-bit 64QAM MCS table). In other cases, only a subset of entries in the MCS table may be configured for the MCS field 410, instead of setting both MSBs 415 to zero. In other cases, a six-bit MCS table may be used, but with one or more of the following constraints: 1) no scaling entries are sent with signaling (e.g., if the UE receives such permission, it may discard the DCI); 2) only up to 64-QAM entries are sent with signaling, or 3) retransmission of the MCS is prohibited (i.e., the MCS between 59 and 63 of the MCS table 300).

[0132] As noted above, the base station can activate and deactivate the SPS at the UE. In some cases, when the UE is configured using the six-bit MCS field, SPS activation can be verified based on the values ​​in the different DCI fields as indicated in Table 1, and SPS deactivation can be verified based on the values ​​in the different DCI fields as indicated in Table 2.

[0138] Figure 5 Examples of a process flow 500 supporting rate matching and semi-persistent scheduling configuration in wireless communications are shown according to various aspects of this disclosure. In some examples, process flow 500 may be implemented in various aspects of wireless communication systems 100 or 200. Process flow 500 may include UE 115-b and base station 105-b, which may be examples of UE 115 and base station 105 described herein. Process flow 500 may implement techniques for rate matching and SPS configuration according to this disclosure.

[0139] At 505, UE 115-b and base station 105-b can establish communication. In some cases, during connection establishment (e.g., RRC connection establishment or RRC connection reconfiguration), base station 105-b can configure UE 115-b to have a six-bit MCS table, which can indicate an MCS independent of the highest MCS of the configured CQI table.

[0140] At 510, UE 115-b may optionally transmit capability information indicating whether UE 115-b has the capability for higher modulation orders (such as 256QAM or 1024QAM). In some cases, UE 115-b may transmit capability information based on its current status. For example, if UE 115-b has relatively low battery power or is equal to or close to its high thermal limit, it may transmit an indication that UE 115-b can only use a modulation order of 64QAM (or lower).

[0141] At point 515, base station 105-b can configure CQI, MCS, and SPS parameters, and these parameters can be sent to UE 115-b at point 520. In some cases, CQI parameters can be configured in a CQI table at UE 115-b. According to the techniques described above, the MCS configuration can indicate whether base station 105-a can transmit an MCS exceeding the highest modulation order in the CQI table. If UE 115-b has already provided capability information, the configuration information can indicate whether a higher-order modulation (e.g., 256QAM or 1024AM) will be used.

[0142] At 525, UE 115-b can optionally set the RF front-end power based on the configuration information provided by base station 105-b. When only a relatively low modulation order can be used for transmission to UE 115-b, the RF front-end power can be set to a low-fidelity mode that consumes relatively low power, while when a higher modulation order can be used, the RF front-end power can be set to a high-fidelity mode that consumes relatively more power.

[0143] At point 530, base station 105-b can allocate radio resources to UE 115-b. Base station 105-b can allocate a certain amount of radio resources for downlink transmission and can also select the MCS used for downlink transmission. Base station 105-b can format downlink control information indicating the allocated resources and MCS, and can send control information to UE 115-b at point 535.

[0144] At 540, UE 115-b can determine one or more rate matching parameters for downlink transmission. UE 115-b can determine such rate matching parameters according to one or more of the techniques described above. For example, in some cases, the modulation order indicated in the control information may exceed the highest modulation order associated with the configured CQI table, and UE 115-b can determine rate matching based on the higher modulation order. In other cases, base station 105-b can schedule downlink transmission such that the modulation order does not exceed the maximum modulation order of the configured CQI table.

[0145] At 545, UE 115-b can optionally determine SPS activation or deactivation. In some cases, activation or deactivation can be determined at least in part based on predetermined values ​​(such as those shown in Tables 1 and 2) of a predetermined set of fields in the control information.

[0146] At position 550, base station 105-b can transmit downlink transmissions (such as PDSCH transmissions), and UE 115-b can receive downlink transmissions. UE 115-b can buffer the received downlink transmission signal in a soft buffer according to determined rate matching parameters. Subsequently, UE 115-b can attempt to decode the buffered signal, and thus decode the downlink transmission. If decoding fails, a negative acknowledgment can be sent to base station 105-b, followed by a retransmission, and the received retransmission signal can be added to the soft buffer to attempt further decoding.

[0156] CQI component 720 can recognize a CQI table that provides one or more parameters associated with one or more modulation orders used for transmission between the UE and the base station.

[0157] MCS component 725 can receive control information for downlink transmission from the base station, the control information including a first index value for a first entry in the MCS table, wherein the first entry in the MCS table indicates a first modulation order independent of one or more modulation orders in the CQI table.

[0158] The rate matching component 730 can determine the rate matching parameters for downlink transmission based on the first modulation order or at least one item in the CQI table.

[0159] The configuration manager 735 can receive SPS configuration from the base station, decode control information from the base station based on the SPS configuration, and determine whether SPS communication is activated based on the decoding. In some cases, the control information includes an MCS field. When the control information is for SPS communication, the MCS field is decoded according to a first interpretation; and when the control information is for non-SPS communication, the MCS field is decoded according to a second interpretation.

[0161] Figure 8 Block diagram 800 of a communication manager 805 supporting rate matching and semi-persistent scheduling configuration in wireless communications is shown according to various aspects of this disclosure. The communication manager 805 may be an example of aspects of the communication manager 615, communication manager 715, or communication manager 910 described herein. The communication manager 805 may include a CQI component 810, an MCS component 815, a rate matching component 820, an RF power component 825, an RRC component 830, a transport block size component 835, a capability indication component 840, a configuration manager 845, and an SPS component 850. Each of these modules may communicate directly or indirectly with each other (e.g., via one or more buses).

[0162] CQI component 810 can recognize a CQI table that provides one or more parameters associated with one or more modulation orders used for transmission between the UE and the base station.

[0163] MCS component 815 can receive control information for downlink transmission from the base station, the control information including a first index value for a first entry in the MCS table, wherein the first entry in the MCS table indicates a first modulation order independent of one or more modulation orders in the CQI table. In some examples, MCS component 815 may discard the control information when the first modulation order exceeds the maximum modulation order among one or more modulation orders in the CQI table. In other examples, MCS component 815 may determine that the first modulation order exceeds the maximum modulation order among one or more modulation orders in the CQI table and determine a rate matching parameter based on the highest entry in the MCS table with the modulation order supported by the UE. In some cases, the rate matching parameter is based on the highest supported modulation order supported by the UE for the radio frequency band or band combination used for downlink transmission.

[0164] In some examples, the MCS component 815 may receive second control information from the base station for the second downlink transmission, the second control information including a second index value for a second entry in the MCS table. In some examples, the MCS component 815 may receive the second downlink transmission based on a first modulation order and determined rate matching parameters.

[0165] In some examples, a capability indication may be provided to the base station to indicate that a higher modulation order can be transmitted, and the MCS component 815 may receive a modulation order indication in response to the capability indication to indicate that the base station will transmit one or more downlink transmissions with a modulation order exceeding the maximum modulation order indicated by the CQI table.

[0166] In some examples, the MCS component 815 can process control information based on modulation order indication. For example, if the CQI table is 256QAM and the UE is not configured to receive transmissions with a modulation order exceeding the highest modulation order in the CQI table, the UE will discard control information with entries for 1024QAM.

[0167] The rate matching component 820 can determine rate matching parameters for downlink transmission based on a first modulation order or at least one item in the CQI table. In some examples, the rate matching component 820 can receive a first downlink transmission based on the determined rate matching parameters and the first modulation order.

[0169] SPS component 850 can decode control information from a base station based on SPS configuration. The control information includes an MCS field. When the control information is for SPS communication, the MCS field is decoded according to a first interpretation; when the control information is for non-SPS communication, the MCS field is decoded according to a second interpretation. The MCS field according to the second interpretation is capable of transmitting a modulation order exceeding 256QAM. In some examples, SPS component 850 can determine whether SPS communication is activated based on the decoding. In some examples, the MCS field is a six-bit MCS field, and a subset of bits from the six-bit MCS field is used for the first interpretation. In some examples, retransmission of information in the MCS field is disabled for the first interpretation.

[0170] In some examples, the SPS component 850 can determine that one or more fields in the control information are set to predetermined values ​​indicating that SPS communication is activated. These fields include an MCS field, in which the two most significant bits set to zero indicate that SPS communication is activated. In some examples, second control information from the base station indicating that SPS communication is deactivated can be decoded, wherein the MCS field of the second control information includes a six-bit field in which each bit is set to one, and the SPS component 850 can abort SPS communication. In some cases, the MCS field for a first interpretation can indicate a first subset of entries in the MCS table, and the MCS field for a second interpretation can indicate both a first subset of entries in the MCS table and a second subset of entries in the MCS table that is different from the first subset. In some cases, the second subset of entries includes: one or more entries in the MCS table indicating scaling parameters, one or more entries indicating modulation orders exceeding 64QAM modulation orders, one or more entries for MCS retransmission, or any combination thereof.

[0171] The RF power component 825 can set the power of the receiver circuitry based on the maximum modulation order among one or more modulation orders in the CQI table. In some examples, the RF power component 825 can select the operating power of one or more receiver components for the UE based on a modulation order indication.

[0172] RRC component 830 can receive RRC signaling, which includes a modulation order transmitted by signaling that is different from the modulation order indicated in the first entry of the MCS table.

In some examples, the transport block size component 835 can compare the first transport block size with a maximum transport block size, which is identified based on the maximum modulation order among one or more modulation orders in a CQI table. In some examples, the transport block size component 835 can receive downlink transmission when the first transport block size is less than or equal to the maximum transport block size. In some examples, the transport block size component 835 can discard control information when the first transport block size exceeds the maximum transport block size.

[0174] The capability indication component 840 can send a capability indication to the base station, the capability indication being used to indicate that the UE is capable of operating at a modulation order exceeding the maximum modulation order indicated by the CQI table.
