[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 201,054, filed April 9, 2021, entitled "RATE MATCHING FOR MULTI-SLOT UPLINK SHARED CHANNEL TRANSMISSION," and U.S. Nonprovisional Patent Application No. 17 / 658,398, filed April 7, 2022, entitled "RATE MATCHING FOR MULTI-SLOT UPLINK SHARED CHANNEL TRANSMISSION," which are expressly incorporated by reference into this specification.

[0002] Aspects of the present disclosure relate generally to wireless communications, and in particular to techniques and apparatus for rate matching for multi-slot uplink shared channel transmissions. [Background technology]

[0003]

[0003] Wireless communication systems have been widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth or transmit power). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0004]

[0004] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that allows different user equipment (UE) to communicate on a city, national, regional, or even global scale. New Radio (NR), sometimes referred to as 5G, is a set of extensions to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, lowering costs, improving services, utilizing new spectrum, and better integrating with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM or SC-FDMA (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, LTE and NR technologies need to be further improved. Preferably, these improvements are applicable to other multiple access technologies and the telecommunications standards that employ these technologies.

[0005]

[0005] In some situations, it may be beneficial for a UE to use an interleaver process to vary bits of a wireless transmission in an attempt to improve the performance and quality of the transmission. Some wireless transmissions may span multiple slots, such as a single Physical Uplink Shared Channel (PUSCH) transmitted on two or more consecutive slots, or a single PUSCH transmitted in two or more segments, each of which occupies two or more consecutive slots. Although the interleaving process is designed to improve transmission performance, when a PUSCH or other transmission spans multiple slots, the interleaving process becomes more complex and less efficient. Summary of the Invention

In some aspects, the method includes selecting coded bits of a plurality of coded bits on one of a per slot basis for each of a plurality of slots or a per segment basis for each of a plurality of segments for communication on the multi-slot transmission occasion, each segment including one of the one or more sets of continuous time domain resources and spanning at least two slots.

[0018]

[0031] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout the present disclosure. Rather, these aspects are provided so that the disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art will appreciate that the scope of the present disclosure covers any aspect of the present disclosure disclosed herein, whether implemented independently of other aspects of the present disclosure or combined with other aspects of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any amount of the aspects described herein. Furthermore, the scope of the present disclosure is intended to cover such an apparatus or method practiced using other structures, functions, or structures and functions in addition to or other than the various aspects of the present disclosure described herein. Any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0019]

[0032] Several aspects of a telecommunications system are now presented with reference to various apparatus and techniques that are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0020]

[0033] Various aspects relate generally to code block interleaving for multi-slot uplink shared channel transmissions on a slot-by-slot or segment-by-segment basis. Some aspects relate more particularly to selecting coded bits on a slot-by-slot or segment-by-segment basis for a physical uplink shared channel (PUSCH) transmission communication spanning multiple slots, and interleaving the coded bits on a slot-by-segment or segment-by-segment basis. In some aspects, in a PUSCH transmission occasion that spans multiple slots, the UE may interleave bits of the PUSCH for each of the multiple slots. In some aspects, in a PUSCH transmission occasion that spans multiple segments, each segment including a respective set of consecutive slots, the UE may interleave bits of the PUSCH for each set of consecutive slots.

[0021]

[0034] Certain aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages: In some examples, slot-by-slot or segment-by-segment interleaving provides more efficient uplink control information (UCI) multiplexing on the PUSCH. In some examples, the described techniques may be used to reduce the latency involved in decision-making processes related to UCI multiplexing. In some examples, the described techniques may be used to improve the quality and performance of network transmissions, such as PUSCH or other transmissions that span multiple slots. Furthermore, the use of code block interleaving for multi-slot uplink shared channel transmissions, on a slot-by-segment or segment-by-slot basis, may reduce the complexity of current UE interleaving processes and provide efficiency improvements for the UE, which may enable the UE to consume power, communication, network, and computing resources more efficiently.

[0022]

[0035] FIG. 1 illustrates an example of a wireless network according to the present disclosure. The wireless network may be or include elements of a 5G (NR) network or an LTE network, among other examples. The wireless network may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, or transmit / receive point (TRP), among other examples. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​a BS or a BS subsystem serving this coverage area, depending on the context in which the term is used.

[0023]

[0036] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs that have an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. A BS may support one or more (e.g., three) cells.

[0024]

[0037] The wireless network may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, or relay BSs. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network. For example, a macro BS may have a high transmit power level (e.g., 5-40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1-2 watts). In the example shown in FIG. 1, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A network controller 130 may couple to the set of BSs 120a, 120b, 110a, and 110b and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, eg, directly or indirectly via wireless or wireline backhaul.

[0025]

[0038] In some aspects, the cells may not be fixed; rather, the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected to each other or to one or more other BSs or network nodes (not shown) in a wireless network through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0026]

[0039] The wireless network may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to enable communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, or a relay, among other examples.

[0027]

[0040] The UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout a wireless network, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, or station, among other examples. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate over a wireless medium.

[0028]

[0041] Some UEs may be considered as machine type communication (MTC) UEs or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs include, among examples, a robot, a drone, a remote device, a sensor, a meter, a monitor, or a location tag that may communicate with, for example, a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). The UE 120 may be included in a housing that stores components of the UE 120, such as a processor component or a memory component, among examples.

[0029]

[0042] In general, any amount of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies or frequency channels. A frequency may be referred to as a carrier, among other examples. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0030]

[0043] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate with each other directly (e.g., without using a base station 110 as an intermediary) using one or more sidelink channels. For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-anything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), mesh networks, or combinations thereof. In such examples, the UEs 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by the base station 110.

[0031]

[0044] Devices of a wireless network may communicate using an electromagnetic spectrum, which may be subdivided into various classes, bands, or channels based on frequency or wavelength. For example, devices of a wireless network may communicate using an operating band having a first frequency range (FR1), which may range from 410 MHz to 7.125 GHz. As another example, devices of a wireless network may communicate using an operating band having a second frequency range (FR2), which may range from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. FR1 is often referred to as the "sub-6 GHz" band, although a portion of FR1 is greater than 6 GHz. Similarly, FR2 is often referred to as "millimeter wave" even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the International Telecommunications Union (ITU). Thus, unless otherwise specified, it should be understood that the term "sub-6 GHz" may broadly refer to frequencies below 6 GHz, frequencies in FR1, mid-band frequencies (e.g., greater than 7.125 GHz), or combinations thereof. Similarly, unless otherwise specified, it should be understood that the term "millimeter wave" may broadly refer to frequencies in the EHF band, frequencies in FR2, mid-band frequencies (e.g., less than 24.25 GHz), or combinations thereof. The frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0032]

[0045] In some aspects, the term "base station" (e.g., base station 110) or "network node" or "network entity" may refer to an aggregated base station, a disaggregated base station (e.g., as described with respect to FIG. 9), an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station", "network node", or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near-real-time (Near-RT) RAN intelligent controller (RIC), or a non-real-time (Non-RT) RIC, or a combination thereof. In some aspects, the term "base station", "network node", or "network entity" may refer to one device configured to perform one or more functions, such as those described herein with respect to base station 110. In some aspects, the term "base station", "network node", or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, several different devices (which may be located at the same geographic location or different geographic locations) may each be configured to perform at least a portion of the functions or to duplicate the performance of at least a portion of the functions, and the term "base station," "network node," or "network entity" may refer to any one or more of those different devices. In some aspects, the term "base station," "network node," or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects two or more base station functions may be instantiated on a single device.In some aspects, the terms "base station," "network node," or "network entity" may refer to one of the base station functions and not another. In this manner, a single device may include two or more base stations.

[0033]

[0046] 2 is a diagram illustrating an example base station in communication with a UE in a wireless network in accordance with the present disclosure. The base station may correspond to base station 110 of FIG. 1. Similarly, the UE may correspond to UE 120 of FIG. 1.

[0034]

[0047] The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1. At the base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode) the data for each UE based at least in part on the selected MCS(es) for that UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information and control information (e.g., CQI requests, grants, or higher layer signaling) (e.g., for semi-static resource partitioning information (SRPI), among other examples) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals and synchronization signals. A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each MOD 232 may process a respective output symbol stream (e.g., for OFDM, among other examples) to obtain an output sample stream. Each MOD 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from MODs 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0035]

[0048] At the UE 120, antennas 252a-252r may receive downlink signals from the base station 110 or other base stations and may provide received signals to R demodulators (DEMODs) 254a-254r, respectively. Each DEMOD 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each DEMOD 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R DEMODs 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., decode) the detected symbols and provide decoded data for the UE 120 to a data sink 260 and provide decoded control and system information to a controller / processor 280. The term “controller / processor” may refer to one or more controllers, one or more processors, or a combination of one or more controllers and one or more processors. The channel processor may determine one or more of a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, or a CQI parameter, among other examples.

The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, further processed by the MODs 254a-254r (e.g., for Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) or Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM)), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., the MOD / DEMOD 254) of the UE 120 may be included in the modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, a modulator 254, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, or a TX MIMO processor 266. The transceiver may be used by a processor (e.g., a controller / processor 280) and a memory 282 to implement aspects of any of the methods described herein.

[0039]

[0052] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the DEMOD 232, detected by a MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate to the network controller 130 via the communication unit 244.

For example, the one or more instructions, when executed by one or more processors of the base station 110 or UE 120 (e.g., directly or after compilation, translation, or interpretation), may cause the one or more processors, UE 120, or base station 110 to perform or direct operations, such as process 1200 of FIG. 12, process 1300 of FIG. 13, or other processes described herein.

[0047]

[0060] 3 is a diagram illustrating an example of an uplink transmit coding chain according to the present disclosure. The coding may be used for transmission of a data payload in a wireless network, such as via a PUSCH or a physical downlink shared channel (PDSCH). The operations of FIG. 3 may be performed by a transmitter, such as a UE (e.g., UE 120) or a base station (e.g., base station 110).

[0048]

[0061] The coding chain may be based at least in part on the MCS indicated at 305. The MCS is an index indicating a modulation order and code rate for a communication. For example, the MCS may indicate how many bits may be transmitted per resource element. The modulation indicates the number of bits (whether parity bits or information bits) per resource element, and the code rate indicates the ratio between information bits and parity bits for encoding. Generally, the MCS is indicated via scheduling information for a given communication, such as in the downlink control information (DCI).

[0049]

[0062] At 310, the transmitter may determine a transport block size (TBS) based at least in part on the MCS. The TBS indicates how many bits should be passed from the medium access control (MAC) layer to the physical layer in one instance of an uplink shared channel transmission, which may span two or more slots. For example, the payload for the physical layer (such as in a PUSCH or PDSCH) is a transport block. The transport block may include a number of bits determined at least in part based on the MCS and a number of physical resource blocks (PRBs) to be used to transmit the transport block.

[0050]

[0063] At 315, the transmitter receives a transport block a i For example, the transport block may include the number of bits indicated by the TBS of the transport block. At 320, the UE may append a cyclic redundancy check (CRC) to the transport block to generate the transport block b i The CRC aids in error detection. The CRC may be generated using a cyclic generator polynomial and may be appended to the end of the transport block.

[0051]

[0064] At 325, the transmitter may determine a base graph (BG) for the transport block, where the BG is a parameter for determining parity bits for transmission based at least in part on the TBS and code rate (BG1 is for transport blocks with larger TBS, BG2 is for transport blocks with smaller TBS).

[0052]

[0065] At 330, the transmitter iIn the example shown in FIG. 3, the transmitter may perform code block (CB) segmentation for the one or more code blocks c. "CB segmentation" refers to segmentation of a transport block (TB) to form one or more code blocks for channel coding and rate matching. Each code block may be coded separately, as described below. For example, steps indicated by reference numerals 335-350 may be performed for each separate code block of the one or more code blocks. At 335, the transmitter appends one or more CRCs to the one or more code blocks to generate the code block(s) c. ri For example, the transmitter may form one or more code blocks c ri A per-code-block CRC determination and insertion may be performed on , which aids in early error detection.

[0053]

[0066] At 340, the transmitter receives one or more code blocks c ri , and the coded bit d ri More generally, the transmitter may perform channel coding according to one or more parameters, such as the BG determined in 320. The LDPC coding may be performed by forming a plurality of coded bits d ri In some aspects, the coded bits may be referred to as a coded code block. ri is a code block ri It is separate from.

[0054]

[0067] At 345, the transmitter may perform bit selection. “Bit selection” refers to selecting coded bits e (sometimes called encoded bits) for interleaving and concatenation. ri (where the set of selected coded bits is denoted by E). For example, selecting coded bits e ri is the number of encoded bits d riIn some cases, the "bit selection", limited buffer rate matching (LBRM), and / or bit interleaving are referred to as "rate matching". As shown, the bit selection is determined by the redundancy version index (rv id ), LBRM index (I LBRM ), and LBRM transport block size (TBS LBRM )

[0055]

[0068] The transmitter may select the number of coded bits per code block. The number of coded bits to be transmitted in a particular transmission (e.g., slot, PUSCH) for code block index r is E r There can be one or two different values ​​for the number of coded bits per code block (e.g., the number of rate-matched bits across multiple code blocks, E rmay take value X and / or value Y for each code block r since it is not always possible to divide the available resources equally across all code blocks). The code blocks may be aligned to RE boundaries (e.g., a single resource element carrying a particular modulation symbol may only contain bits corresponding to a single code block). G may represent the actual number of bits available for transmission (e.g., the total number of coded bits available for transmission of a transport block) for a single-slot transmission (i.e., for a transmission occasion occupying only one slot). C' may represent the number of code blocks to be transmitted, where C' is according to the Code Block Group Transmission Information (CBGTI) field if the CBGTI field is present in the DCI, or C (i.e., all code blocks) if the CBGTI field is not present. The bits may be consecutively selected (e.g., read) from the circular buffer. The starting position k0 for the code block may be determined by the redundancy version (RV). In the case of per-segment or per-slot rate matching, the starting position may be determined based at least in part on stored information, such as the last position where the transmitter read bits for the previous slot or segment. The number of bits read for a transport block is E, and the number of bits read for a given coded bit sequence e ri excluding the filler bit, E r It is.

[0056]

[0069] The techniques described herein provide for per-slot rate matching and per-segment rate matching. Further explanation is provided below. When per-slot rate matching is used, G may be defined as the actual number of transmission bits available per slot, and E rmay be defined as the number of coded bits of the rth code block to be transmitted in a given slot. If per-segment rate matching is used, G may be defined as the actual number of transmission bits available per slot, and E r may be defined as the number of coded bits of the rth code block to be transmitted in a given segment.

[0057]

[0070] At 350, the transmitter performs interleaving to generate one or more interleaved coded bit sequences f ri Interleaving can be done on a per-code-block basis (for each code block c ri Recall that the "interleaving" is performed on the basis of the coded bit sequence f(x,y) in some cases. In some cases, the "interleaving" is referred to as "channel interleaving". In some aspects, the transmitter may perform row-column interleaving. In row-column interleaving, the selected bits are arranged into several rows corresponding to the modulation orders. The selected bits are then read column by column such that the bits from each row are interleaved with each other. In redundancy version 0, the interleaver may be a systematic-bit priority interleaver such that systematic bits are placed in more reliable positions in the quadrature amplitude modulation (QAM) symbols. When binary phase shift keying (BPSK) is used, the interleaver may have no effect on the bit stream. At 355, the transmitter interleaves the coded bit sequence f(x,y) with the coded bit sequence f(x,y) in a manner similar to that described in the previous section. ri Implement code block concatenation on (one or more) code blocks c ri (separate from code block g i may be generated.

[0058]

[0071] After the code block is generated, the transmitter may transmit the code block. For example, the transmitter may perform scrambling, modulation, layer mapping, antenna port mapping, mapping to one or more virtual resource blocks, and mapping from the virtual resource blocks to physical resource blocks. The transmitter may then transmit a communication carrying a coded transport block that is based at least in part on the code block.

[0059]

[0072] The receiver may receive a communication carrying a coded transport block on the time-frequency resources allocated for this transmission occasion. The receiver estimates the channel using a demodulation reference signal transmitted along with the coded bits. Using the estimated channel and the received signal, the receiver performs a demapping operation on each resource element of the received signal to obtain soft information about the bit values ​​of the coded transport block. The soft information may take the form of a log-likelihood ratio (such as the probability based on the received signal that the transmitted bit is 0 or 1). This probability may be quantized to several levels (e.g., 16 or 32 levels). In the extreme case where the probability is quantized to two levels, the soft information degenerates into "hard" information. For example, a two-level quantization of the probability may represent the receiver's best guess as to what the transmitted bit was, with no further nuance to this guess.

[0060]

[0073] The receiver may perform deinterleaving on the soft information to obtain deinterleaved soft information. The receiver may concatenate the deinterleaved soft information to obtain concatenated soft information. The receiver may decode the concatenated soft information to infer one or more code blocks of the communication.

[0061]

[0074] 4 is a diagram illustrating an example of redundancy version rotation based on uplink transmission occasion in accordance with the present disclosure. A UE (such as UE 120) may apply redundancy version rotation to PUSCH repetitions to transmit different redundancy versions of the PUSCH repetitions at different transmission occasions (or in different slots or different segments of a transmission occasion).

[0062]

[0075] A "redundancy version" (RV) of a PUSCH repetition may be used to select a set of coded bits to be transmitted for that PUSCH repetition. The RV may indicate a starting location in a circular buffer, such as circular buffer 405. Using the RV rotation, the UE transmits different sets of coded bits in different PUSCH repetitions. For example, the UE may store bits for uplink transmission in a circular buffer 405 (stored in a memory of the UE). The circular buffer 405 stores information bits 410 (which may be referred to as systematic bits) and parity bits 415 (which may be referred to as parity check bits). The information bits 410 may include data to be transmitted, and the parity bits 415 may include a linear combination of the data (i.e., of the information bits 410). The UE may encode the information bits 410, the parity bits 415, or a combination of the information bits 410 and the parity bits 415 into a set of coded bits and transmit the set of coded bits. The particular bits selected to be included in the set of coded bits for a PUSCH repetition depend on (or are defined by) the RV of that PUSCH repetition. By selecting different combinations of information bits 410 and parity bits 415, the UE improves the reliability of the PUSCH transmission because not all bit positions are associated with the same level of reliability.

[0063]

[0076] As an example, the starting bit location may be defined by a table 440, such as for NR Hybrid Automatic Repeat Request (HARQ) using LDPC codes. The table 440 defines the starting bit location in the circular buffer 405 for a first base graph (BG1) and a second base graph (BG2). The base graphs are parameters for determining the parity bits 415 for transmission based at least in part on the TB size and the code rate (BG1 is for TBs with a larger TB size and BG2 is for TBs with a smaller TB size). Referring to the table, N cb represents the length of the circular buffer 405 (e.g., the number of bits contained in the circular buffer 405), and Z c represents a lifting size based at least in part on the number of information bits 410 and the number of BG columns that correspond to the information bits 410. Table 440 is only an example, and in practice other starting bit locations may be used.

[0064]

[0077] In some examples, a base station (e.g., base station 110) may transmit information such as an RV index to a UE. For example, the base station may transmit an RV index for a PUSCH communication in a DCI that schedules the PUSCH communication. The RV index may indicate a sequence of RVs to be applied to a corresponding sequence of occasions, such as a sequence of PUSCH transmission occasions, a sequence of slots, or a sequence of segments. The UE may increment a counter n (sometimes referred to as index n) for each occasion following (or indicated by) the DCI. The UE may use the information transmitted by the base station (the RV index) and the value of counter n for a particular occasion to determine the RV to be applied to that occasion.

[0065]

[0078] For example, as shown by table 445, for PUSCH repetition type A, if the base station indicates an RV index of 0, the UE may determine the RV to be applied to the nth transmission occasion (for PUSCH repetition type A) by calculating n mod 4, where "mod" represents modulo operation. If n mod 4 = 0 (for transmission occasion 0), the UE applies RV0 to that transmission occasion. If n mod 4 = 1 (for transmission occasion 1), the UE applies RV2 to that transmission occasion. If n mod 4 = 2 (for transmission occasion 2), the UE applies RV3 to that transmission occasion. If n mod 4 = 3 (for transmission occasion 3), the UE applies RV1 to that transmission occasion. As shown, the RV index may have a value of 0, 1, 2, or 3, each of which corresponds to a different sequence of RVs (e.g., a different order for RV0, RV1, RV2, and RV3).

[0066]

[0079] Similarly, for PUSCH repetition type B, if the base station indicates an RV index of 0, the UE 120 may determine the RV to be applied to the nth actual repetition (of PUSCH repetition type B) by calculating n mod 4. If n mod 4 = 0 (for actual repetition 0), the UE applies RV0 to the actual repetition. If n mod 4 = 1 (for actual repetition 1), the UE applies RV2 to the actual repetition. If n mod 4 = 2 (for actual repetition 2), the UE applies RV3 to the actual repetition. If n mod 4 = 3 (e.g., for actual repetition 3), the UE applies RV1 to the actual repetition.

[0067]

[0080] Some techniques described herein use multi-slot transmission occasions, such as multi-slot PUSCH occasions. In such examples, RVs may be assigned per PUSCH (such that a PUSCH occupying multiple consecutive slots on a multi-slot transmission occasion has a given RV) or per segment (such that a segment associated with a PUSCH occupying multiple sets of consecutive slots is associated with a given RV). In such cases, the RV index may be incremented according to how the RV is assigned (i.e., per PUSCH, per segment, or per slot, such as for each slot of a multi-slot transmission). Multi-slot transmission occasions are described in more detail below.

[0068]

[0081] FIG. 5 illustrates an example of a multi-slot uplink shared channel transmission according to the present disclosure. Slots are labeled as "U" to indicate an uplink slot (i.e., a slot with a threshold number of configured or indicated uplink symbols) or "D" to indicate a downlink slot (i.e., a slot with a threshold number of configured or indicated downlink symbols). Two options are shown for a UE to transmit PUSCH repetitions on a set of continuous time domain resources, where the PUSCH repetitions span multiple slots and / or multiple segments, as described in further detail herein. PUSCH repetitions that span multiple slots or multiple segments may be referred to herein as multi-slot PUSCH transmissions. Although techniques are described herein with respect to PUSCH repetitions and multi-slot PUSCH transmissions, these techniques may be applied to various types of uplink repetitions, such as uplink data repetitions, uplink control repetitions (such as physical uplink control channel (PUCCH) repetitions), etc.

[0069]

[0082] Repetition, such as uplink repetition or downlink repetition, may be used to improve reliability, such as for ultra-reliable low latency communication (URLLC) or for UEs located in geographic areas with poor channel conditions (such as cell edges). When repetition is used, a transmitter repeats transmission of a communication multiple times. For example, a UE may transmit an initial uplink communication and may repeat (i.e., retransmit) the transmission of the uplink communication one or more times. Each repetition may include different coded bits according to different RVs, as described herein. Thus, a receiver may attempt to combine multiple repetitions to improve the likelihood of successfully decoding the payload of the multiple repetitions.

[0070]

[0083] As used herein, the term "repetition" is used to refer to an initial communication and also to refer to a repeated transmission of the initial communication. For example, if a UE is configured to transmit four repetitions, the UE may transmit an initial transmission and may transmit three repeated transmissions of that initial transmission. Thus, each transmission (whether the transmission is an initial transmission or a retransmission) counts as a repetition. The repetitions may be transmitted in a transmission occasion, sometimes referred to as a transmission instance. In these examples, the transmission occasion is a multi-slot transmission occasion that allows for the transmission of a multi-slot PUSCH transmission.

[0071]

[0084] In a first type of multi-slot PUSCH transmission shown at 510 and referred to as option (a), each repetition and each multi-slot transmission occasion spans a set of contiguous resources (such as symbols or slots). Option (a) may, for example, enable a UE to transmit a transport block that spans a set of contiguous slots in a single transmission occasion. For example, in the first multi-slot PUSCH transmission 515 including a code block associated with RV0, a ​​repetition that spans two contiguous slot sets is shown. As used herein, "spanning across a set of contiguous slots" means "including at least one symbol of each slot of the set of contiguous slots."

[0072]

[0085] In a second type of multi-slot PUSCH transmission, shown at 520 and referred to as option (b), each repetition spans two or more segments, where a segment includes a set of consecutive slots. Option (b) may, for example, enable a UE to transmit a transport block that spans multiple sets of consecutive slots in a single transmission occasion. For example, in a second multi-slot PUSCH transmission 525 including a code block associated with RV0, a ​​repetition that spans two sets of consecutive slots is shown. Thus, the repetition is transmitted over two segments of a transmission occasion, where a first segment occupies at least a portion of the first and second slots of the slot pattern and a second segment occupies at least a portion of the sixth and seventh slots of the slot pattern.

[0073]

[0086] In some aspects, RV rotation may be performed on a per-slot basis. For example, each slot of a multi-slot transmission occasion may be assigned a respective RV index. In some aspects, RV rotation may be performed on a per-transmission occasion basis. For example, each transmission occasion may be assigned a respective RV index. In some aspects, RV rotation may be performed on a per-segment basis. For example, each segment of a transmission occasion may be assigned a respective RV index.

[0074]

[0087] In some aspects, rate matching (denoted as "RM") may be performed on a per transmission occasion basis, as described elsewhere herein. Rate matching per transmission occasion is denoted by reference numeral 530 in option (a) and reference numeral 535 in option (b). In other aspects, rate matching may be performed on a per slot basis, as described elsewhere herein. In option (a), denoted by reference numeral 540, a first rate matching may be performed for a first slot of a transmission occasion, and a second rate matching may be performed for a second slot of a transmission occasion. In option (b), denoted by reference numeral 545, a respective rate matching may be performed for each slot of a transmission occasion (i.e., twice for the two slots of the first segment and twice for the two slots of the second segment). In yet other aspects, rate matching may be performed on a per segment basis, as described elsewhere herein and denoted by reference numeral 550.

[0075]

[0088] FIG. 6 illustrates an example of an interleaver design per transmission occasion for multi-slot uplink shared channel transmission according to the present disclosure. A UE may interleave a code block of bits for transmission to another device, such as a base station. The interleaver process is designed to improve transmission performance, for example, by distributing the transmitted bits over time to achieve a desired bit error distribution. For example, a set of bits is mapped to a modulation symbol. Not all bits mapped to a modulation symbol are conveyed with equal reliability. The interleaver uses the difference between the reliabilities of the bits mapped to the modulation symbol and arranges the information bits such that the bits occupy locations that enjoy higher reliability before being mapped to the modulation symbol.

[0076]

[0089] As indicated by reference numeral 610, the UE may use a first type of multi-slot PUSCH transmission, referred to as option (a), to transmit coded bits of a PUSCH that span multiple slots. In this example, a first multi-slot PUSCH transmission occasion 615 (also referred to as a multi-slot transmission occasion) spans a set of two consecutive slots (slot 0 and slot 1) and includes bits corresponding to RV0. The UE may obtain a code block 620 for the first multi-slot PUSCH transmission occasion 615 from a circular buffer based at least in part on a starting position indicated by an RV index of RV0. For example, the UE may select rate matching bits (represented by E) from the circular buffer to obtain the code block 620. As indicated by reference numeral 625, the UE may perform interleaving on the code block to form multiple interleaved coded bit sequences with reconstructed data via one or more interleaving processes described herein, such as row-column interleaving. As shown, interleaving the code block distributes the bits of the code block across two slots of the multi-slot PUSCH transmission occasion, resulting in a first subset of coded bits 630 being transmitted via a first slot (slot 0) of the multi-slot PUSCH transmission occasion and a second subset of coded bits 635 being transmitted via a second slot (slot 1) of the multi-slot PUSCH transmission occasion 615. After interleaving, the UE may transmit the coded bits via the multi-slot PUSCH transmission occasion 615. For example, the UE may concatenate the coded and interleaved bits across all code blocks and transmit the entire coded transport block.

[0077]

[0090] In some aspects, interleaving may be performed on a per transmission occasion basis (as in FIG. 6) and RV rotation may be performed on a per slot basis. In other aspects, interleaving may be performed on a per transmission occasion basis and RV rotation may be performed on a per transmission occasion basis. In other aspects, interleaving may be performed on a per transmission occasion basis and RV rotation may be performed on a per segment basis.

[0078]

[0091] The interleaving process improves transmission performance. However, when a PUSCH or other transmission spans multiple slots, the UE may need to store the status of the transmission across the slots. In addition, the UE may need to store information indicating how much of the interleaved sequence has been transmitted while also storing the sequence that has not been transmitted. This increases the complexity involved and the resources used by the UE when interleaving and transmitting the PUSCH over multiple slots, which may lead to the UE consuming power, communication, network, and computing resources inefficiently to interleave multi-slot transmissions, making UCI multiplexing inefficient or unfeasible.

[0079]

[0092] Various aspects relate generally to code block interleaving for multi-slot uplink shared channel transmissions on a slot-by-slot or segment-by-segment basis. Some aspects relate more particularly to selecting coded bits for a code block of a PUSCH transmission communication spanning multiple slots on a slot-by-segment or segment-by-slot basis and interleaving the coded bits on a slot-by-segment or segment-by-slot basis. In some aspects, in a PUSCH transmission occasion that spans multiple slots, a UE may interleave bits of a PUSCH for each of the multiple slots. In some aspects, in a PUSCH transmission occasion that spans multiple segments, each including multiple slots, a UE may interleave bits of a PUSCH for each segment.

[0080]

[0093] Certain aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages: In some examples, the described techniques may be used to improve the quality and performance of network transmissions, such as PUSCH or other transmissions that span multiple slots. Furthermore, the use of code block interleaving for multi-slot uplink shared channel transmissions, on a slot-by-slot or segment-by-segment basis, may reduce the complexity of current UE interleaving processes and provide efficiency improvements for the UE, which may enable the UE to more efficiently consume power, communication, network, and computing resources and to perform UCI multiplexing while reducing the latency involved in the decision-making process related to UCI multiplexing.

[0081]

[0094] FIG. 7 illustrates an example of a per-slot interleaver design for multi-slot uplink shared channel transmission in accordance with the present disclosure.

[0082]

[0095] The UE may use a first type of multi-slot PUSCH transmission, option (a) (depicted by 710), to transmit coded bits of a PUSCH that span multiple slots, including slot 0 and slot 1. In this example, the first multi-slot PUSCH transmission occasion 715 spans a set of two consecutive slots and includes bits corresponding to RV0. The UE may obtain a code block 720 for the first multi-slot PUSCH transmission occasion 715 from the circular buffer based at least in part on the starting position indicated by the RV index. As shown, the UE may select a portion of the code block to be used for each slot of the multi-slot PUSCH transmission occasion on a slot-by-slot basis and select a first subset of selected bits 725 for transmission over the first slot (slot 0) of the multi-slot PUSCH transmission occasion and select a second subset of selected bits 730 for transmission over the second slot (slot 1) of the multi-slot PUSCH transmission occasion 715.

[0083]

[0096] As shown, the UE may perform interleaving on each portion of the code block to form two sequences of interleaved coded bits 735 and 740 with reconstructed data via one or more interleaving processes described herein. As shown, interleaving a subset of the code block 720 distributes the bits of the original code block across two slots of a multi-slot PUSCH transmission occasion, with each slot associated with interleaved data via a separate interleaving process. After interleaving, the UE may transmit the coded bits via the multi-slot PUSCH transmission occasion. For example, the UE may concatenate the coded and interleaved bits to form a code block and transmit the code block.

[0084]

[0097] In some aspects, interleaving may be performed on a per-slot basis (as in FIG. 7) and RV rotation may be performed on a per-slot basis. In other aspects, interleaving may be performed on a per-slot basis and RV rotation may be performed on a per-transmission occasion basis. In yet other aspects, interleaving may be performed on a per-slot basis and RV rotation may be performed on a per-segment basis.

[0085]

[0098] Certain aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques may be used to improve the quality and performance of network transmissions, such as PUSCH or other transmissions that span multiple slots. When selecting bits and performing interleaving on a slot-by-slot basis, the UE may experience reduced overhead in that only the starting position in the circular buffer is stored for each slot, reducing the need to store additional information regarding the state of the transmission. Furthermore, there may be no need to buffer the bits to be transmitted, since storing the circular buffer is sufficient to reference the rate-matched bits. Selecting bits and performing interleaving on a slot-by-slot basis also allows UCI multiplexing to be performed on a slot-by-slot basis. In this manner, the use of code block interleaving for multi-slot uplink shared channel transmissions on a slot-by-slot basis may reduce the complexity of current UE interleaving processes and provide efficiency improvements for the UE, which may allow the UE to consume power, communication, network, and computing resources more efficiently.

[0086]

[0099] FIG. 8 illustrates an example of a per-segment interleaver design for multi-slot uplink shared channel transmission in accordance with the present disclosure.

[0087]

[0100] The UE may use a second type of multi-slot PUSCH transmission, option (b) (shown at 810), to transmit coded bits of a PUSCH that span multiple segments, or sets, of multiple consecutive slots. In this example, the first multi-slot PUSCH transmission occasion 815 spans two segments, with each segment corresponding to two consecutive slots. Additionally, the first multi-slot PUSCH transmission occasion 815 includes a bit corresponding to RV0. As shown, the UE selects (E1, E2, E3, E4) for the first multi-slot PUSCH transmission occasion 815 from the circular buffer based on the starting position indicated by the RV index. r,p RV index)。 An example of circular buffer reading and bit selection for rate matching per segment is shown by reference numeral 1105 in FIG. 11. As shown, the UE may determine parameters for rate matching for the first segment 1145, and the UE may identify and read rate matching bits from the circular buffer (starting at a starting position indicated by the RV index) according to the parameters for rate matching for the first segment 1145. The UE may store (e.g., in a memory) a point 1150 in the circular buffer at which the UE stops reading bits that rate match the bits for the first segment 1145. The UE may then determine parameters for rate matching for the second segment 1155, and the UE may identify and read rate matching bits from the circular buffer according to the parameters for rate matching for the second segment 1155, starting at the point 1150 in the circular buffer stored by the UE. For example, the UE may read the bits consumed in the first segment 1145 from the circular buffer and then read the bits consumed in the second segment 1155 from the circular buffer. Thus, per-segment rate matching is enabled.

[0088]

[0101] For per-segment rate matching, the UE may perform rate matching across each segment of the first multi-slot PUSCH transmission occasion 815. For example, G (described above with respect to FIG. 3) may be defined as the actual number of transmission bits available per segment (i.e., G p ). E r may be defined as the number of coded bits of the rth code block to be transmitted in a given segment (i.e., E r,p ).

[0089]

[0102] The following algorithm is an example of how per-segment rate matching may be implemented: The following algorithm may be applied for each segment of a transmission occasion using option (b), as shown in FIG.

[0090] Let E be the rate matching output sequence length for the r-th coded block in segment p. r,p where E r,p The value of is determined as follows:

[0091] Set j=0 for r=0~C-1 if the rth coded block is not scheduled for transmission as indicated by the CBGTI according to clause 5.1.7.2 for the DL-SCH and clause 6.1.5.2 for the UL-SCH in [6, TS38.214]

[0093] Where: - N L is the number of transmission layers onto which the transport block is mapped, - Q m is the modulation order, - Gp is the total number of coded bits available for transmission of a transport block in the pth segment of a transmission occasion, - If the CBGTI is not present in the DCI that schedules the transport block, then C'=C, and if the CBGTI is present in the DCI that schedules the transport block, C' is the number of scheduled code blocks of the transport block.

[0103]

[0104] FIG. 11 illustrates an example 1100 of per-slot rate matching for option (b). As shown, the UE may determine parameters for rate matching for a first slot of a first segment 1110 (labeled slot 0), and the UE may identify and read rate matching bits from the circular buffer (starting at a starting position indicated by an RV index) in accordance with the parameters for rate matching for the first slot of the segment 1110. The UE may store (e.g., in a memory) a first point 1115 in the circular buffer at which the UE stops reading bits that rate match bits for the first slot of the first segment 1110. The UE may then determine parameters for rate matching for a second slot of a first segment 1120 (labeled slot 1), and the UE may identify and read rate matching bits from the circular buffer in accordance with the parameters for rate matching for the second slot of the first segment, starting at the first point 1115 in the circular buffer. The UE may store (e.g., in memory) a second point 1125 in the circular buffer at which the UE stops reading bits that rate match bits for the second slot of the first segment 1110. The UE may determine parameters for rate matching for the first slot of the second segment 1130 and may identify and read rate matching bits from the circular buffer (starting at the second point 1125) in accordance with the parameters for rate matching for the first slot of the second segment 1130. The UE may store (e.g., in memory) a third point 1135 in the circular buffer at which the UE stops reading bits that rate match bits for the first slot of the second segment 1130.The UE may then determine parameters for rate matching for the second slot of the second segment 1140 and may identify and read rate matching bits from the circular buffer in accordance with the parameters for rate matching for the second slot of the second segment 1140, starting at a third point 1135 in the circular buffer. For example, the UE may read only the bits consumed in a given slot for rate matching for the given slot.

[0104]

[0105] In some aspects, the UE may perform slot-by-slot rate matching using RV cycling. For example, consider a multi-slot PUSCH transmission occasion with four non-contiguous segments of two slots each. The UE may perform slot-by-slot rate matching and interleaving (as described above) for each of a plurality of first slots (such as each slot of the first N segments of the four segments) using a first RV index. The UE may then perform slot-by-slot rate matching and interleaving for each of a plurality of second slots (such as each remaining slot of the four segments) using a second RV index. In some aspects, the plurality of first slots may be based at least in part on a sequence of slots, such as information indicating the number of slots for which slot-by-slot rate matching should be performed before moving to the next RV index in the RV cycle.

[0105]

[0106] For rate matching per transmission occasion, the UE may determine parameters for rate matching for the first multi-slot PUSCH transmission occasion 815 and may identify and read rate matching bits from the circular buffer (starting at the starting position indicated by the RV index) according to the parameters for rate matching for the first multi-slot PUSCH transmission occasion 815. For example, the UE may read all bits for rate matching for a transmission occasion at once (regardless of how many slots or segments are included in the transmission occasion).

[0106]

[0107] As indicated by reference numeral 830, the UE may perform interleaving on each set of coded bits to form two sequences of interleaved coded bits with reconstructed data via one or more interleaving processes described herein. As shown, each segment is associated with interleaved data via a separate interleaving process. After interleaving, the UE may transmit the coded bits via a multi-slot PUSCH transmission occasion that includes both segments.

[0107]

[0108] In some aspects, interleaving may be performed on a per-segment basis (as in FIG. 8) and RV rotation may be performed on a per-segment basis. In other aspects, interleaving may be performed on a per-segment basis and RV rotation may be performed on a per-transmission occasion basis.

[0108]

[0109] In some aspects, the UE may determine whether to perform interleaving. For example, the UE may determine whether to perform interleaving based at least in part on a condition at the UE or based at least in part on an indication from the base station. In some aspects, the decision of whether to perform interleaving (whether determined by the UE or signaled by the base station) may be based at least in part on the MCS of the communication. For example, if the MCS meets a threshold, the UE may perform interleaving, and if the MCS cannot meet the threshold, the UE may not perform interleaving. In some aspects, the threshold may be an MCS associated with 16 quadrature amplitude modulation (16QAM). For example, the UE may not perform interleaving for communications associated with BPSK or quadrature phase shift keying (QPSK), and may perform interleaving for communications with 16QAM or higher. This may be beneficial because interleaving may generally be deactivated for lower modulation schemes without significant detrimental impact, which conserves resources in the UE associated with interleaving and the base station associated with deinterleaving.

[0109]

[0110] Particular aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages: In some examples, the described techniques may be used to improve the quality and performance of network transmissions, such as PUSCH or other transmissions that span multiple slots. When selecting bits and performing interleaving on a per-segment basis, the UE may experience reduced overhead in that only the starting position in the circular buffer is stored for each slot, reducing the need to store additional information regarding the state of the transmission. Furthermore, there may be no need to buffer bits to be transmitted, since storing the circular buffer is sufficient to reference the rate-matched bits. In this manner, the use of code block interleaving for multi-slot uplink shared channel transmissions on a per-slot or per-segment basis may reduce the complexity of the current UE interleaving process and provide efficiency improvements for the UE, which may allow the UE to consume power, communication, network, and computing resources more efficiently.

[0110]

[0111] Although the interleaving techniques described with respect to Figures 6, 7, and 8 have been described primarily in the context of uplink communications, these techniques may also be applied for downlink communications.

[0111]

[0112] FIG. 9 illustrates an example of signaling associated with a multi-slot uplink shared channel transmission according to the present disclosure. As illustrated in FIG. 9, a UE (e.g., UE 120) may communicate (e.g., transmit uplink transmissions and / or receive downlink transmissions) with a base station (e.g., base station 110). In some aspects, the UE may communicate with another UE via one or more sidelink communications (e.g., in addition to or instead of communicating with the base station). The UE and the base station may be part of a wireless network (e.g., wireless network 100).

[0112]

[0113] In a first operation 905, a capability signaling may be transmitted by the UE and received by the base station. The capability signaling may identify one or more capabilities of the UE. For example, the capability signaling may indicate one or more features supported by the UE.

[0113]

[0114] In some aspects, the capability signaling may indicate whether the UE supports multi-slot transmission of a transport block. For example, the capability signaling may indicate that the UE supports multi-slot transmission of a transport block with contiguous resources only and with a single code block transmission. As another example, the capability signaling may indicate that the UE supports multi-slot transmission of a transport block with contiguous or non-contiguous resources and with a single code block transmission. As yet another example, the capability signaling may indicate that the UE supports multi-slot transmission of a transport block with contiguous resources only and with multiple code block transmission. As yet another example, the capability signaling may indicate that the UE supports multi-slot transmission of a transport block with contiguous or non-contiguous resources and with multiple code block transmission.

[0114]

[0115] In some aspects, the capability signaling may indicate support for a rate matching configuration. The rate matching configuration may include per-slot rate matching, per-transmission occasion rate matching, or per-segment rate matching. For example, the UE may transmit capability signaling indicating support for one or more of per-slot rate matching (e.g., which may be contingent on the resources of the transmission occasion being contiguous and / or on a single code block transmission) or per-segment rate matching (e.g., which may be contiguous on the resources of the transmission occasion and / or on a single code block transmission).

[0115]

[0116] In some aspects, the capability signaling may indicate support associated with interleaving. For example, the capability signaling may indicate whether the UE is capable of dynamically turning on or off (e.g., activating or deactivating) the interleaver. For example, the UE may determine whether to activate or deactivate the interleaver based at least in part on a multi-slot transmission of a transport block (e.g., all instances may have the interleaver turned off) or based at least in part on a multi-slot transmission of a transport block that spans non-contiguous resources.

[0116]

[0117] In a second operation 910, the base station may transmit, and the UE may receive, an indication of one or more sets of contiguous time domain resources for a multi-slot transmission (MST) occasion spanning multiple slots. In some aspects, the UE may receive the indication from another device (e.g., from another base station or another UE). In some aspects, the indication may indicate that the base station is capable of receiving code blocks transmitted using one or more types of bit selection and interleaving processes described herein. The indication may be provided via radio resource control (RRC) signaling, MAC signaling, DCI, a combination thereof, and the like. In some aspects, the indication may include configuration information for the MST occasion. Additionally or alternatively, the indication may include scheduling information for transmissions on the MST occasion.

[0117]

[0118] In some aspects, the one or more sets of contiguous time domain resources for an MST occasion may include (e.g., consist of) a single set of contiguous time domain resources that spans multiple slots, where the multiple slots are contiguous with one another (as in option (a) described above with reference to Figures 5, 6, and 7). In other aspects, the one or more sets of contiguous time domain resources for an MST occasion may include multiple sets of contiguous time domain resources. In such examples, each set of contiguous time domain resources may span two or more contiguous slots, where the different sets of contiguous time domain resources are not contiguous with one another. Furthermore, each set of contiguous time domain resources of the multiple sets of contiguous time domain resources may be associated with a corresponding segment (as in option (b) described above with reference to Figures 5 and 8).

[0118]

[0119] In some aspects, the UE and / or base station may trigger per-slot or per-segment rate matching. For example, the UE may autonomously trigger per-slot or per-segment rate matching or the base station may transmit signaling to the UE that triggers per-slot or per-segment rate matching. In some aspects, the UE and / or base station may determine the rate matching type or configuration (e.g., per-slot, per-segment, or per-transmission occasion rate matching). In some aspects, per-slot rate matching may be the default operation mode for multi-slot transmissions, regardless of whether the resource allocation for the multi-slot transmission is contiguous or not, and regardless of whether the transport block of the multi-slot transmission may be encoded in a single code block or multiple code blocks. In some aspects, per-slot rate matching may be triggered if a multi-slot transmission occasion spans non-contiguous resources. In some aspects, per-slot rate matching may be triggered if the transport block of the multi-slot transmission is encoded across multiple code blocks. In some aspects, the base station may transmit signaling indicating the rate matching type. For example, the rate matching type for multi-slot transmission may be RRC configured.

[0119]

[0120] In some aspects, the UE and / or base station may trigger per-slot or per-segment rate matching based at least in part on a restriction on per-slot or per-segment rate matching. The restriction may indicate the number of slots or segments in which rate matching may be performed (such as a sequence of slots or segments in which rate matching may be performed). For example, the restriction may indicate that per-slot or per-segment rate matching may not span more than K uplink slots (where K is an integer). In some aspects, the restriction may indicate that per-slot or per-segment rate matching may not span more than K slots in which multi-slot transmissions are performed. In some aspects, the restriction may indicate that per-slot or per-segment rate matching may not span across semi-static downlink slots. In some aspects, the restriction may indicate that per-slot or per-segment rate matching may not span across discontinuous slots. Once per-slot or per-segment rate matching over a sequence of slots is terminated, rate matching for the next set of slots may be governed by a new RV index, and per-slot or per-segment rate matching may resume. Thus, the UE or base station may implement per-slot or per-segment rate matching with RV cycling.

[0120]

[0121] In a third operation 915, the UE may select coded bits for communication on an MST occasion on a slot-by-slot or segment-by-segment basis. For example, in some aspects, the UE may select coded bits of a plurality of coded bits for communication on an MST occasion on a slot-by-slot basis for each of a plurality of slots or on a segment-by-segment basis for each of a plurality of segments, where each segment spans a plurality of slots and includes one of a set of continuous time domain resources. In some aspects, the selected bits may be interleaved to form a code block (such as one or more code blocks), as described below.

[0121]

[0122] In some aspects, when selecting coded bits on a slot-by-slot basis, the UE may select a first subset of the plurality of bits for a first slot of an MST occasion and a second subset of the plurality of bits for a second slot of the MST occasion. In such an example, the first slot and the second slot may be contiguous.

[0122]

[0123] In some aspects, when selecting coded bits on a per-segment basis, the UE may select a first subset of the plurality of bits for a first segment of an MST occasion and a second subset of the plurality of bits for a second segment of a multi-slot transmission occasion. In such an example, the first and second segments may be associated with a single physical channel.

[0123]

[0124] In some aspects, the communication is a PUSCH transmission including a single transport block, and the multi-slot transmission occasion is a multi-slot PUSCH transmission. In some aspects, the code block may be one of a plurality of code blocks of the communication. In such an example, selecting coded bits on a slot-by-slot or segment-by-segment basis may be based at least in part on the code block spanning across two slots or two segments. For example, the UE may not need to select coded bits on a slot-by-segment or segment-by-segment basis in situations where the code block does not span multiple slots or segments.

[0124]

[0125] In a fourth operation 920, the UE may interleave the coded bits on a slot-by-slot or segment-by-segment basis to form one or more interleaved coded bit sequences. For example, when interleaving on a slot-by-slot basis over multiple consecutive slots, the UE may perform a separate interleaver process for the coded bits of each of the slots, as described with respect to FIG. 7. As another example, when interleaving on a segment-by-segment basis over multiple segments (each segment including multiple consecutive slots), the UE may perform a separate interleaver process for the coded bits of each segment, as described with respect to FIG. 8.

[0125]

[0126] In a fifth operation 925, a communication may be transmitted by the UE and received by the base station. For example, the communication may include a coded transport block generated at least in part based on one or more interleaved coded bit sequences (e.g., multiple interleaved coded bit sequences). As mentioned above, in some aspects the communication may be a PUSCH transmission including a single transport block and the MST occasion may be a multi-slot PUSCH transmission occasion.

[0126]

[0127] In a sixth operation 930, the base station may demap the encoded code block to obtain soft information on the transmitted bits. For example, in some aspects, the base station may demap the encoded code block to obtain the soft information as described in further detail with respect to FIG.

[0127]

[0128] In a seventh operation 935, the base station may deinterleave the soft information to form deinterleaved soft information on a slot-by-slot or segment-by-segment basis. In some aspects, the base station may deinterleave on a segment-by-segment basis for each of a plurality of segments, where each segment spans at least two slots and includes one of one or more sets of contiguous time domain resources, as described with respect to FIG.

[0128]

[0129] In some aspects, when deinterleaving on a slot-by-slot basis, the base station may deinterleave a first subset of the soft information for a first slot of an MST occasion and deinterleave a second subset of the soft information for a second slot of the MST occasion. In such an example, the first slot and the second slot may be contiguous with one another. In some aspects, an MST occasion may consist of a single set of contiguous time domain resources spanning the first slot and the second slot.

[0129]

[0130] In some aspects, when deinterleaving on a per-segment basis, the base station may deinterleave a first subset of the soft information for a first segment of the MST occasion and deinterleave a second subset of the soft information for a second segment of the MST occasion. In such examples, the first segment and the second segment may be associated with a single physical channel. In some aspects, the one or more sets of contiguous time domain resources for the MST occasion may include multiple sets of contiguous time domain resources, where each set of contiguous time domain resources may span two or more contiguous slots. In such examples, the different sets of contiguous time domain resources may not be contiguous with one another, where each set of contiguous time domain resources is associated with a corresponding segment.

[0130]

[0131] In some aspects, the code block may be one of multiple code blocks of a communication. In such an example, the base station may deinterleave on a slot-by-slot or segment-by-segment basis based at least in part on the code block spanning two slots or two segments. For example, the base station may not deinterleave the code block on a slot-by-slot or segment-by-segment basis in situations where the code block spans only a single slot.

[0131]

[0132] In an eighth operation 940, the base station may concatenate the deinterleaved soft information to form concatenated soft information. In a ninth operation 945, the base station may decode the concatenated soft information to infer one or more code blocks of the communication. For example, the base station may decode transmitted bits based on the concatenated soft information presented as input to the decoder. The decoding block partitions the concatenated soft information to identify soft information associated with each encoded code block. Each such partition is then used to decode the actual transmitted bits corresponding to that code block.

[0132]

[0133] FIG. 10 illustrates an example of a per-slot interleaver design for multi-slot uplink shared channel transmission in accordance with the present disclosure.

[0133]

[0134] The UE may use a first type of multi-slot PUSCH transmission, option (a) (denoted by 1010), to transmit coded bits of a PUSCH that spans multiple slots, including slot 0 and slot 1. In this example, the first multi-slot PUSCH transmission occasion 1015 spans a set of two consecutive slots and includes bits corresponding to RV0. The UE may obtain respective sets of coded bits 1020 and 1025 for the first multi-slot PUSCH transmission occasion 1015 from the circular buffer based at least in part on the starting position indicated by the RV index.

[0134]

[0135] For slot-by-slot rate matching, the UE may perform rate matching across each slot of the first multi-slot PUSCH transmission occasion 1015. For example, G (described above with respect to FIG. 3) may be defined as the actual number of transmission bits available per slot. E r may be defined as the number of coded bits of the rth code block to be transmitted in a given slot.

[0135]

[0136]

[0151] [Table 1]

[0152] As shown, the UE may perform interleaving on sets of coded bits 1020 and 1025 to form two sequences of interleaved coded bits 1030 and 1035 with data reconstructed via one or more interleaving processes described herein. After interleaving, the UE may transmit the coded bits via a multi-slot PUSCH transmission occasion. For example, the UE may concatenate the coded and interleaved bits to form a code block and transmit the code block.

[0153] In some aspects, interleaving may be performed on a per-slot basis (as in FIG. 10) and RV rotation may be performed on a per-slot basis. In other aspects, interleaving may be performed on a per-slot basis and RV rotation may be performed on a per-transmission occasion basis. In yet other aspects, interleaving may be performed on a per-slot basis and RV rotation may be performed on a per-segment basis.

[0154]

[0142] Certain aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques may be used to improve the quality and performance of network transmissions, such as PUSCH or other transmissions that span multiple slots. When selecting bits and performing interleaving on a slot-by-slot basis, the UE may experience reduced overhead in that only the starting position in the circular buffer is stored for each slot, reducing the need to store additional information regarding the state of the transmission. Furthermore, there may be no need to buffer the bits to be transmitted, since storing the circular buffer is sufficient to reference the rate-matched bits. Selecting bits and performing interleaving on a slot-by-slot basis also allows UCI multiplexing to be performed on a slot-by-slot basis. In this manner, the use of code block interleaving for multi-slot uplink shared channel transmissions on a slot-by-slot basis may reduce the complexity of the current UE interleaving process and provide efficiency improvements for the UE, which may allow the UE to consume power, communication, network, and computing resources more efficiently.

[0155] 12 is a flow chart illustrating an example process 1200, for example, performed by a UE, in accordance with the present disclosure. The example process 1200 is an example in which a UE (for example, UE 120) performs operations associated with interleaver design for a multi-slot uplink.

[0156] 12, in some aspects, the process 1200 may include receiving an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion spanning multiple slots (block 1210). For example, the UE may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion spanning multiple slots (such as by using the receiving component 1402, shown in FIG. 14), as described above.

[0157] 12, in some aspects, the process 1200 may include selecting a coded bit of the plurality of coded bits on one of a slot-by-slot basis for each of a plurality of slots or a segment-by-segment basis for each of a plurality of segments for communication on a multi-slot transmission occasion, where each segment includes one of one of one or more sets of continuous time domain resources and spans across at least two slots (block 1220). For example, the UE may select (e.g., from a circular buffer) a coded bit of the plurality of coded bits on one of a slot-by-slot basis for each of a plurality of slots or a segment-by-segment basis for each of a plurality of segments for communication on a multi-slot transmission occasion, where each segment includes one of one of one or more sets of continuous time domain resources and spans across at least two slots (e.g., by using a selection component 1410, shown in FIG. 14), as described above.

[0158] 12, in some aspects, process 1200 may include interleaving the coded bits on one of a slot-by-slot or a segment-by-segment basis to form one or more interleaved coded bit sequences for the code block (block 1230). For example, the UE may interleave the coded bits on one of a slot-by-segment or a segment-by-segment basis to form one or more interleaved coded bit sequences for the code block (such as by using interleaving component 1412, shown in FIG. 14), as described above.

[0159] 12, in some aspects, the process 1200 may include transmitting a communication including the one or more interleaved coded bit sequences (block 1240). For example, the UE may transmit a communication including the one or more interleaved coded bit sequences as described above (such as by using the transmitting component 1406, shown in FIG. 14).
