A user equipment (UE) may receive, from a network entity, a message indicating assistance information including a decoding order for a first set of repetitions for data transmission, a decoder iteration instruction, or both. The UE may monitor and receive the first set of repetitions from the network entity and decode the first set of repetitions based on the assistance information from the network entity.

Technical Field

[0003] The following relates to wireless communications, including network entity assisted decoding for repetition-based transmissions. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to 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, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication for communication devices, which may be referred to as user equipment (UE).

[0052] In some wireless communication systems, wireless devices may use repetitions to convey signaling to reduce signaling errors and, therefore, improve transmission reliability and latency. For example, there may be multiple situations where a receiving device may receive different transmissions of the same transport block, data, or information (e.g., repetitions). In some cases, the receiving device may have multiple antennas (e.g., 8 antennas) to receive the repetitions, may receive the repetitions from multiple transmit-receive points (TRPs), may receive downlink control channel repetitions with log-likelihood ratios (LLRs) combined between the timings of the repetitions, or may receive downlink shared channel repetitions, or any combination thereof. In some examples, the receiving device may determine how to decode the repetitions without assistance from a network entity. However, determining how to decode the repetitions may result in high power consumption at the receiving device and inefficient use of time-frequency resources due to unnecessary decoding of the repetitions.

[0053] The technology of the present disclosure describes a network entity providing auxiliary information to a user equipment (UE) on how to decode repetitions in order to reduce power consumption and improve efficiency associated with the use of time-frequency resources. The network entity may send auxiliary information to the UE before transmitting the repetitions, or during a period when the UE is waiting for the repetitions and has determined to decode the repetitions at a later time, and the auxiliary information may include a decoding order, decoder iteration information, a repetition combination order, or any combination thereof. In some examples, the UE may wait to receive a threshold number of repetitions or until a certain index (e.g., a repetition copy or a time slot index) before decoding. In some cases, the UE may perform a threshold number of decoder iterations on the repetition and then combine the repetition with one or more other repetitions. Additionally or alternatively, the UE may perform two or more repetitions before performing a threshold number of decoder iterations to reduce power consumption associated with decoding repetitions of a certain number of iterations. After decoding, the UE may send a feedback message indicating whether the repetitions were successfully decoded, such as an acknowledgment (ACK) message or a negative acknowledgment (NACK) message.

[0054] Various aspects of the present disclosure are first described in the context of a wireless communication system. Additional aspects of the present disclosure are described with reference to wireless communication systems and process flows. Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to network entity-assisted decoding for repetition-based transmission.

[0055] Figure 1An example of a wireless communication system 100 that supports network entity assisted decoding for repetition-based transmission according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0056] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices that take different forms or have different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UEs 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entities 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UEs 115 and the network entities 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entities 105 and the UEs 115 may support communication of signals according to one or more radio access technologies (RATs).

[0057] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both stationary and mobile at different times. The UEs 115 may be devices that take different forms or have different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 Other UEs 115 or network entities 105 are shown communicating.

[0058] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from the second node.

[0059] In some examples, network entities 105 can communicate with core network 130, or with each other, or both. For example, network entities 105 can communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 can communicate with each other via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols), either directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130). In some examples, network entities 105 can communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol), or any combination thereof. Backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 can be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0060] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a next-generation Node B, or a gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home Node B, a Home evolved Node B, or other suitable terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in a converged (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as the base station 140).

[0061] In some examples, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that can be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 can include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, smart radio head, remote radio head (RRH), remote radio unit (RRU), or transmit receive point (TRP). One or more components of the network entity 105 in the disaggregated RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0062] The functional split between CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of the protocol stack can be employed between CU 160 and DU 165 such that CU 160 can support one or more layers of the protocol stack and DU 165 can support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as Layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer may be performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and the DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., an open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0063] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources used for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication link 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by the DU 165 of the coupled IAB donor. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0064] For example, an access network (AN) or RAN may include communications between an access node (e.g., an IAB donor), an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node that has a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via the F1 interface according to a protocol that defines signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0065] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node toward child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay transmissions for UEs through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115 .

[0066] For example, IAB node 104 may be referred to as a parent node supporting communications for child IAB nodes, or as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection to the core network 130 (e.g., backhaul communication link 120) and may serve as a parent node for IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to UE 115 via IAB node 104, or may directly signal transmissions to UE 115, or both. The CU 160 of the IAB donor may signal the establishment of a communication link to IAB node 104 via the F1 interface, and IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to UE 115) via the DU 165. That is, data may be relayed to and from IAB node 104 via signaling via the NR Uu interface of the MT to IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0067] Where the techniques described herein are applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support network entity assisted decoding for repetition-based transmission as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0068] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects, such as appliances or vehicles, meters, etc.

[0069] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0070] The UE 115 and the network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 can support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between those devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0071] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel raster used for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by a UE 115 via the carrier, or in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0072] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0073] A carrier may be associated with a particular bandwidth of RF spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communication using a particular carrier bandwidth, or may be capable of being configured to support communication using one of the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0074] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to the resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order of the modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0075] One or more parameter sets for a carrier may be supported, and the parameter set may include subcarrier spacing (Δf) and cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be constrained to one or more active BWPs.

[0076] The time interval for the network entity 105 or the UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, for which Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0077] Each frame may include a plurality of consecutive subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0078] A subframe, slot, mini-slot, or symbol may be the minimum scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a Transmit Time Interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0079] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling over downlink carriers, for example, using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0080] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier) and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier) ​​used to distinguish between adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, etc.

[0081] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. Small cells may be associated with a lower power network entity 105 (e.g., a lower power base station 140) than a macro cell, and the small cell may operate using the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. Small cells may provide unrestricted access to UEs 115 that have a service subscription with the network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells and may also use one or more component carriers to support communications via the one or more cells.

[0082] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0083] In some examples, network entities 105 (e.g., base stations 140, RUs 170) can be mobile and, therefore, provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies can overlap, but the different coverage areas 110 can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies can be supported by different network entities 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0084] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0085] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents it to a person interacting with the application. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other equipment. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging.

[0086] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not concurrent transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0087] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication can include private or group communications and can be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms "ultra-reliable," "low latency," and "ultra-reliable low latency" are used interchangeably herein.

[0088] In some examples, a UE 115 can be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication can be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which can support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group can be outside the coverage area 110 of the network entity 105 or can otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0089] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0090] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0091] The wireless communication system 100 can operate using one or more frequency bands that can range from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features (which can be referred to as clusters), but these waves can penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Communication using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) than communication using the lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0092] The wireless communication system 100 may also operate in the ultra-high frequency (SHF) region (also known as the centimeter band) using spectrum in the range of 3 GHz to 30 GHz or in the extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices may be smaller and closer together than UHF antennas. In some examples, such technology may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary by country or regulatory agency.

[0093] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating using an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using the unlicensed band may be based on a carrier aggregation configuration combined with component carriers operating using a licensed band (e.g., LAA). Operations using the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0094] A network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input, multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations 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 examples, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support RF beamforming for signals transmitted via the antenna ports.

[0095] The network entity 105 or the UE 115 may use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device 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 information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0096] 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 device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. The adjustments associated with each of these antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0097] The network entity 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the network entity 105 along different directions. For example, the network entity 105 may transmit signals according to different sets of beamforming weights associated with different transmit directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as the network entity 105, or by a receiving device, such as the UE 115) the beam direction for later transmission or reception by the network entity 105.

[0098] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (e.g., receiving network entity 105 or receiving UE 115)). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by network entity 105 along different directions and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0099] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across the system bandwidth or one or more subbands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port-selective codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0100] A receiving device (e.g., UE 115) may perform reception operations according to multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array (e.g., different directional listening weight sets), or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0101] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly for communication via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also support retransmission using error detection, error correction, or both to improve link efficiency. In the control plane, the RRC layer may provide for the establishment, configuration, and maintenance of RRC connections between the UE 115 and the network entity 105 or core network 130 for radio bearers supporting user plane data. The PHY layer may map transport channels to physical channels.

[0102] UE 115 and network entity 105 may support retransmission of data to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a particular time slot for data received via previous symbols in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or based on some other time interval.

[0103] In some examples of wireless communication system 100, a wireless device (e.g., network entity 105, UE 115, or both) may use repetitions to convey signaling to reduce signaling errors and, therefore, improve transmission reliability and latency. For example, there may be multiple situations in which a receiving device (e.g., UE 115) may receive different transmissions of the same transport block, data, or information (e.g., repetitions). In some cases, the receiving device may have multiple antennas (e.g., 8 antennas) to receive repetitions, may receive repetitions from multiple TRPs, may receive downlink control channel repetitions with LLRs combined between the repetitions, may receive downlink shared channel repetitions, or any combination thereof. In some examples, the receiving device may determine how to decode the repetitions without assistance from the network entity. However, determining how to decode the repetitions may result in high power consumption at the receiving device and inefficient use of time-frequency resources due to unnecessary decoding of the repetitions.

[0104] The techniques of this disclosure describe how a network entity 105 provides assistance information to a UE 115 regarding how to decode repetitions in order to reduce power consumption and improve efficiency associated with the use of time-frequency resources. The network entity 105 may send assistance information to the UE 115 before transmitting the repetitions, or during a period when the UE 115 is waiting for the repetitions and has determined to decode the repetitions at a later time. The assistance information may include a decoding order, decoder iteration information, a repetition combining order, or any combination thereof. In some examples, the UE 115 may wait to receive a threshold number of repetitions or until a certain index (e.g., a repetition copy or a time slot index) before decoding. In some cases, the UE 115 may perform a threshold number of decoder iterations on the repetition and then combine the repetition with one or more other repetitions. Additionally or alternatively, the UE 115 may perform two or more repetitions before performing a threshold number of decoder iterations to reduce power consumption associated with decoding repetitions for a certain number of iterations. After decoding, the UE 115 may send a feedback message, such as an ACK message or a NACK message, indicating whether the repetitions were successfully decoded.

[0105] Figure 2 An example of a wireless communication system 200 that supports network entity-assisted decoding for repetition-based transmissions according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 may implement or be implemented by the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115-a and a network entity 105-a (which may represent examples of corresponding devices as described herein). In this example, the UE 115-a may receive one or more data repetitions 230 from the network entity 105-a via a downlink channel 205 and attempt to decode the data repetitions 230 using a first demodulator 220-a and a second demodulator 220-b at a decoder 215. The UE 115-a may send a feedback message 235 to the network entity 105-a via an uplink channel 210, indicating whether the UE 115-a demodulated the data repetitions 230 using the decoder 215. In some examples, UE 115-a may receive data repetition 230 from another UE 115, such as via a sidelink communication link.

[0106] In some cases, UE 115-a may receive different transmissions of the same transport block, data, or information (e.g., data repetitions 230). In some examples, UE 115-a may be configured with an antenna panel 245 having eight antenna elements 250 for receiving data repetitions 230. In some cases, UE 115 may use an increased number of receive antenna elements to enable UE 115 to support higher layer signaling. For example, UE 115-a may be configured with an antenna panel 245 including eight receive antenna elements 250 that may support eight downlink layers. However, this structure may use advanced receiver architectures to decouple the eight different layers (e.g., a MIMO decoder), which may increase the complexity of baseband processing and decoding of data repetitions 230 at UE 115-a.

[0107] In some examples, UE 115-a may utilize an antenna architecture with four receive antennas when receiving data repetitions 230. For example, UE 115-a may receive data repetitions 230 using a first set of antenna elements 250-a and a second set of antenna elements 250-b, where both the first set of antenna elements 250 and the second set of antenna elements 250 include four receive antenna elements. UE 115-a may receive a first data transmission 230-a using the first set of antenna elements 250-a and receive a first data repetition 230-b of the first data transmission 230-a using the second set of antenna elements 250-b. The first data transmission 230-a and the first data repetition 230-b may be copies of the same data transmission, transport block, or information and may both be referred to herein as data repetitions 230.

[0108] In some other cases, UE 115-a may receive data repetitions 230 from multiple TRPs. For example, a first TRP may send a first data repetition 230-a, and a second TRP may send a second data repetition 230-b and a third data repetition 230. Each TRP may use a different time division multiplexing (TDM), frequency division multiplexing (FDM), or space division multiplexing (SDM) scheme to send data repetitions 230. For multi-TRP (mTRP) transmission, there may be different modes for sending data repetitions 230. A first mode may be defined as an ideal backhaul (e.g., relatively high throughput and relatively low latency backhaul, such as a dedicated point-to-point connection using optical fiber) and / or a relatively small latency backhaul between TRPs when a single physical downlink control channel (PDCCH) is used to schedule communications via the TRPs. The first mode may have one continuous wave with different spatial layers from different TRPs. For example, one continuous wave may be mapped to four downlink layers (e.g., layers one to two from a first TRP and layers three to four from a second TRP). A second mode may be defined for ideal and non-ideal backhauls (e.g., backhauls such as digital subscriber line (DSL), microwave, and other backhauls such as relays) when multiple PDCCH channels are used to schedule communications via a TRP. A first PDCCH may schedule a first continuous wave (e.g., transmitted from a first TRP), and a second PDCCH may schedule a second continuous wave (e.g., transmitted from a second TRP). In some cases, the scheduled resources may be overlapping, partially overlapping, or non-overlapping in the time and frequency domains. To distinguish between TRPs, there may be a field (e.g., a HARQ process ID) in the DCI message to indicate whether the grant for the transmission corresponds to a first physical downlink shared channel (PDSCH) (e.g., from a first TRP) or a second PDSCH (e.g., from a second TRP). In mTRP operation, operation in a given serving cell may be defined using two DCI modes. Single DCI mode can be suitable for ideal backhaul and can have different PDSCH schemes (e.g., SDM, FDM, TDM) to improve communication robustness. Multi-DCI mode can be suitable for ideal or non-ideal backhaul. In multi-DCI mode, the carrier aggregation (CA) framework is used for UE 115-a to treat different TRPs as different virtual carrier components (CCs). This mode can be used for UE 115-a to receive data repetitions 230 from multiple TRPs.

[0109] In some cases, when configured to communicate via multiple TRPs, the UE 115-a may be RRC configured with M Transmission Configuration Indication (TCI) states, at least for the purpose of Quasi Co-location (QCL) indication. In some cases, the network entity 105-a may select up to two of the M TCI states using a Medium Access Control-Control Element (MAC-CE). NIn some embodiments, the TCI state may be used for PDSCH QCL indication. In such a case, N bits in a DCI message (e.g., a DCI activation message) may dynamically indicate the TCI state for PDSCH transmission (e.g., N=3). Each TCI state may include at least one set of reference signals (RS) for different QCL types (e.g., downlink RS: synchronization signal blocks (SSBs) and periodic, semi-periodic, and aperiodic CSI-RS / transmit RS).

[0110] In some cases, there may be two modes for DCI messages indicating QCL associations between demodulation reference signals (DMRS) and multiple TRPs. In the first mode, for QCL indication of DMRS for PDSCH via DCI signaling, the TCI field may point to two QCL relationships referring to two sets of RSs for two DMRS port groups. In the first DMRS port group of a layer from the first TRP, the DMRS from the first DMRS port group may be QCLed with the RS from the first TRP. In the second DMRS port group of a layer from the second TRP, the DMRS from the second DMRS port group may be QCLed with the RS from the second TRP. For either group, the DCI signaling may indicate the DMRS port group. For example, the DCI signaling may indicate which port group the DMRS can be derived from. In the second mode, each DCI may correspond to a single QCL relationship (e.g., in the TCI status field) because the layers for scheduled continuous waves may be from a single TRP. Thus, the DCI may be similar to the DCI in a single TRP scenario, and two different DCI messages may correspond to two different QCL relationships associated with the first TRP and the second TRP. Using this DCI signaling, UE 115-a may determine which DMRS to use to demodulate and decode data repetitions 230 received via one or more TRPs.

[0111] In some other cases, UE 115-a may receive PDCCH repetitions (e.g., data repetition 230) with different LLRs between different downlink control information (DCI) opportunities, or UE 115-a may receive PDSCH repetitions (e.g., data repetition 230) of the same data transmission, transport block, or information. Generally, UE 115-a may receive and decode data repetitions 230 from different receive antenna elements 250, multiple TRPs, or PDCCH or PDSCH channels. In some examples, UE 115-a may receive a first data transmission 230-a and then receive one or more repetitions of the first data transmission 230-a (e.g., data repetition 230-b and data repetition 230). In some cases, UE 115-a may receive the first data transmission 230-a and begin decoding the first data transmission 230-a using a decoder 215 at UE 115-a while receiving other data repetitions 230. UE 115-a may decode first data transmission 230-a for a certain number of iterations. After decoding first data transmission 230-a, UE 115-a may decode first data repetition 230-b for a certain number of iterations and then combine decoded data repetition 230-a with decoded data repetition 230-b. UE 115-a may then decode combined data repetition 230 for a certain number of iterations. UE 115-a may continue this process until UE 115-a has decoded and combined all data repetitions 230 received from network entity 105-a (e.g., data repetition 230-a, data repetition 230-b, and data repetition 230).

[0112] Upon decoding all data repetitions 230, UE 115-a may send a feedback message 235 to network entity 105-a via uplink channel 210. In some examples, feedback message 235 may be an example of a HARQ-ACK feedback message. In some cases, UE 115-a may send an ACK indicating that UE 115-a has successfully decoded the data transmission or transport block from data repetition 230. However, in some other cases, UE 115-a may send a NACK indicating that UE 115-a has not successfully decoded the data transmission or transport block from data repetition 230.

[0113] In some examples, the order in which the UE 115-a receives the repetitions may generate decoding problems, such as causing the UE 115-a to be unable to successfully decode the data repetitions 230. For example, the network entity 105-a may dynamically change the transmit power to support power conservation at the network entity 105-a. In some cases, the network entity 105-a may send the first data repetition 230-a using a first power level (e.g., P1) and send the second data repetition 230-b using a second power level (e.g., P2). P2 may be greater than P1, or P2 may be less than P1. As such, the UE 115-a may not be able to correctly or successfully decode the data repetitions 230 based on such power changes. Additionally or alternatively, the decoding process may result in high power consumption levels at the UE 115-a, particularly if the UE 115-a is a low-power device. In such cases, UE 115 - a may not have sufficient power to complete the decoding process as described herein and may send a NACK in feedback message 235 based on the power level of UE 115 - a .

[0114] In some cases, the network entity 105-a may send assistance information 225 to the UE 115-a to enhance the decoding process at the UE 115-a (e.g., via a DCI message). For example, the assistance information 225 from the network entity 105-a may include a decoding order to reduce the complexity of decoding the data repetitions 230 and reduce the power consumption of decoding the data repetitions 230. The decoding order may be based on the path loss from the TRP or the power increase or decrease at the network entity 105-a between the data repetitions 230. In some other cases, the assistance information 225 may include combining parameters for combining the data repetitions 230 or for iteration instructions for the decoder 215. In some examples, the network entity 105-a may determine such combining parameters via sounding reference signal (SRS) measurements from the UE 115-a. For example, the network entity 105-a may use the SRS measurements from the UE 115-a to estimate the quality of the downlink channel at a given time and power level. In some cases, UE 115-a may periodically, semi-persistently, or aperiodically transmit SRS measurements. For example, UE 115-a may transmit SRS measurements to network entity 105-a based on changes in transmit parameters (e.g., an increase or decrease in transmit power) from network entity 105-a. In this way, network entity 105-a may determine the quality of the downlink channel at the transmit power level. In some other examples, the network entity may estimate the quality of the downlink channel based on CSI reports from UE 115-a. Similar to SRS measurements, UE 115-a may periodically, semi-periodically, or aperiodically transmit CSI reports based on changes in transmit parameters at network entity 105-a.

[0115] Additionally or alternatively, network entity 105-a may estimate the quality of the downlink channel based on a history of ACKs from UE 115-a at different power levels or other transmission parameters. For example, UE 115-a may have sent a higher number of ACK messages (compared to NACK messages) at a first power level (e.g., P1) or from a first TRP of network entity 105-a than at a second power level (e.g., P2) or from a second TRP of network entity 105-a. Based on the ACK history, network entity 105-a may determine that data repetitions 230 sent at the first power level or first TRP may be more reliable than data repetitions 230 sent at the second power level or second TRP. In this way, the auxiliary information 225 may indicate to the UE 115-a that the data repetitions 230 corresponding to the first power level or first TRP are to be decoded before other data repetitions, or to combine the data repetitions 230 with other data repetitions from the same TRP or having a similar power level and then decode the combined data repetitions 230, rather than decoding the data repetitions 230 individually.

[0116] In some cases, if UE 115-a has received a certain number of data repetitions 230 and has determined that the data repetitions are to be decoded at a later time, UE 115-a may wait before receiving the next data repetition 230. For example, UE 115-a may receive two data repetitions (e.g., data repetition 230-a and data repetition 230-b) and wait before receiving data repetition 230. During this waiting period, network entity 105-a may determine to transmit assistance information 225 indicating a decoding order or a combining indication to UE 115-a.

[0117] The assistance information 225 may indicate to the UE 115-a when to start decoding, to wait and combine the data repetitions 230 before starting decoding the data repetitions 230, or both. In some cases, the network entity 105-a may send the assistance information 225 to a low-power UE 115. Such a low-power UE 115 may report a NACK in the feedback message 235 because the UE 115 may not have enough power to fully decode each data repetition individually. In this way, the assistance information 225 may indicate to the low-power UE 115 when to decode the data repetitions 230 and which data repetitions 230 to combine before decoding.

[0118] UE 115-a may receive data repetitions 230 via a DCI, non-scheduled DCI, RRC, or MAC-CE message that schedules the PDSCH repetitions. In some cases, network entity 105-a may indicate via assistance information 225 that UE 115-a should wait until UE 115-a receives a certain number of repetitions (Y) or until after a wait period 240 before decoding (e.g., where UE 115-a may receive Y repetitions). In this manner, UE 115-a may be configured with a wait period 240 that indicates to UE 115-a that it should wait until UE 115-a has received at least two data repetitions 230 (e.g., data repetition 230-a and data repetition 230-b) or a given amount of time before decoding data repetitions 230, combining data repetitions 230, or both. Waiting period 240 may be a function of the condition of the data packet, transport block, or information packet (e.g., priority, quality of service (QoS), or latency). For example, network entity 105-a may determine that later data repetitions 230 (e.g., data repetition 230-b and data repetition 230-c) may be more accurate due to the latency or priority of the transmission. Additionally or alternatively, network entity 105-a may determine that to enhance the ability to decode data repetitions 230 (e.g., enhance QoS), UE 115-a should wait to receive multiple repetitions before decoding or combining them.

[0119] In some examples, assistance information 225 from network entity 105-a may indicate a wait period 240 in conjunction with an index of data repetition 230-b indicating that UE 115-a should decode data repetition 230-b before data repetition 230-a. This indication may be determined based on a determination by network entity 105-a that data repetition 230-b may be more reliable or easier to decode than data repetition 230-a. In this manner, UE 115-a may wait to decode any data repetition until UE 115-a has received the indicated data repetition 230-b.

[0120] In some other examples, assistance information 225 may instruct UE 115-a to combine two or more data repetitions 230 and then decode data repetitions 230 using decoder 215 (e.g., a low-density parity-check (LDPC) decoder or a polar code decoder). In such an example, assistance information 225 may instruct UE 115-a to wait for a wait period 240 so that UE 115-a can receive both data repetition 230-a and data repetition 230-b, combine the two data repetitions 230, and then decode the combined data repetition. In this manner, assistance information 225 may save UE 115-b time and processing power because, as opposed to iterating the decoder for each data repetition 230 (e.g., data repetition 230-a and data repetition 230-b) individually and then decoding the combined data repetition 230, UE 115-a may perform a single set of decoder iterations on the combined data repetitions 230. Such a process of waiting for the wait period 240, decoding at the indicated index, or waiting and combining data repetitions may also be applied to data repetitions received from multiple TRPs.

[0121] Instead of using a control message to indicate the assistance information 225, the network entity 105-a may use a redundancy version (RV) sequence to activate the assistance information 225. In some cases, when the UE 115-a receives a number K of identical indices for the same transport block, the UE 115-a may determine that a process as described herein of combining repetitions may be activated or waiting to receive a certain number of repetitions before decoding or combining. For example, the UE 115-a may receive an RRC sequence index RV={0,0,0,0} (e.g., indicating that the UE 115-a has received the same data transmission four times), where the sequence may indicate that the UE 115-a uses a default pattern of RVs {0,2,3,1}, which may be repeated cyclically for additional repetitions. In this manner, the UE 115-a may decode the data repetitions 230 in an order defined by the RRC, MAC-CE, or DCI message (e.g., via the order described by the RV sequence). In some cases, the network entity 105-a may define a non-numeric RV index for the process of decoding the data repetitions 230. UE 115 - a may obtain the decoding sequence from RRC, MAC-CE, or DCI messages. Thus, receiving K number of identical indices may indicate activation or deactivation of the process described herein for receiving the decoding or combining order of data repetitions 230 .

[0122] In some cases, the network entity 105-a may instruct the UE 115-a via the assistance information 225 to run the decoder 215 for a certain number of iterations for the data repetition 230 before combining with one or more other data repetitions 230 or after combining the data repetitions. The instruction may be based on a previous SRS or CSI measurement or a power change at the network entity 105-a. In some examples, the power change at the network entity 105-a may include a power state change or a TCI state change.

[0123] UE 115-a may use the received data repetitions 230 (e.g., one or more PDSCH repetitions or combined PDSCH repetitions) to prepare a CSI report for network entity 105-a. The CSI report may be parameterized by a number or process of decoder iterations (e.g., LDPC iterations). The process may include UE 115-a iterating decoder 215 on a first data repetition 230-a for a number of iterations L1, iterating decoder 215 on a fourth data repetition 230 for a number of iterations L4, and combining the first data repetition 230-a and the fourth data repetition 230. After UE 115-a sends the CSI report, network entity 105-a may determine an updated modulation and coding scheme (MCS), rank, power control configuration, transmission configuration, or any combination thereof, and indicate the updated MCS, rank, power control configuration, power configuration, or any combination thereof to UE 115-a. The power configuration may include MCS, power control configuration, beamforming configuration (e.g., analog and digital beamforming configurations), transmit rank, an indication of which TRPs or TRP panels to use if there are multiple TRPs or TRP panels, or the number of repetitions to receive.

[0124] In some cases, when receiving data repetitions 230 from network entity 105-a or multiple TRPs using antenna panel 245, as indicated by the transmit configuration from network entity 105-a, UE 115-a may interpret a single data transmission as one or more data repetitions 230. For example, if UE 115-a receives a PDSCH or PDCCH transmission from network entity 105-a or a TRP via antenna panel 245, first set of antenna elements 250-a and second set of antenna elements 250-b may both receive the same PDSCH or PDCCH transmission (e.g., data repetition 230) and interpret the single data transmission as two data repetitions 230 of the data transmission (e.g., data repetition 230-a and data repetition 230-b). Additionally or alternatively, UE 115-a may use a first set of antenna elements 250-a to receive a data transmission (e.g., data repetition 230-a) from a first TRP and use a second set of antenna elements 250-a to receive a repetition of the data transmission (e.g., data repetition 230-b) from a second TRP.

[0125] When receiving a transmission and / or repetition, the UE 115-a may demodulate the data repetition 230-a using a first demodulator 220-a and demodulate the data repetition 230-b using a second demodulator 220-b. The UE 115-a may demodulate the communication signal received via the first set of antenna elements 250-a using the first demodulator 220-a and demodulate the communication signal received via the second set of antenna elements 250-b using the second demodulator 220-b. If indicated via the auxiliary information 225, the UE 115-a may combine the LLRs of the demodulated data repetitions 230 to decode the data transmission using the decoder 215. The LLR is the log domain ratio of the probability that a bit of the data repetition 230 is zero to the probability that a bit of the data repetition 230 is one. For the data repetition 230-a, the data repetition 230-a may be represented by an intrinsic LLR vector LLR comprising M bits. D1 =[L 1,1 ,L 1,2 ,...,L 1,k ,...,L 1,M ] is defined, where each position k in the LLR vector may correspond to an LLR of a bit in data repetition 230-a. For data repetition 230-b, data repetition 230 may be represented by an intrinsic LLR vector LLR containing M bits. D2 =[L 2,1 ,L 2,2 ,...,L 2,k ,...,L 2,M For each data repetition in data repetition 230, UE 115-a may perform L for all bits k. 1,k With L2,k A comparison may be made (e.g., UE 115-a may compare each bit of data repetition 230-a with each bit of data repetition 230-b). Given an optimizable positive parameter threshold τ, which may be based on communication history, SRS measurements, or CSI reports, and if the signs of each LLR for each bit k in data repetition 230 are equal to one another, UE 115 may compare the ratio of the absolute value LLRs for each bit k to parameter threshold τ to determine how to combine the LLRs for data repetitions 230.

[0126] Thus, instructions for combining LLR vectors into combined LLR vectors when the LLRs of bits between data repetitions 230 may be of different or same sign may be defined according to one or more rules. For example, if sign(L 1.k )≠sign(L 2,k )and Then UE 115-a may not combine the LLRs for position k and may select L 1,k The LLR at position k is the combined LLR vector. If sign(L 1.k )≠sign(L 2,k )and Then UE 115-a may add the two LLRs together, and the updated LLR at position k of the combined LLR vector may be L 1,k +L 2,k If sign(L 1.k )=sign(L 2,k ), then UE 115-a may add the two LLRs together, and the updated LLR at position k of the combined LLR vector may be L 1,k +L 2,k . As such, when combining data repetition 230 - a and data repetition 230 - b , UE 115 - a may compare each bit of data repetition 230 to generate combined data repetition 230 with a combined LLR vector for decoding at decoder 215 .

[0127] In some examples, when UE 115-a may use a combining coefficient α to combine the LLRs at position k of the LRR vectors. For example, when combining the LLRs at position k, as described herein, UE 115-a may use a combining coefficient to combine the LLRs such that αL 1,k +(1-α)L 2,k Furthermore, when UE 115-a combines the LLR vectors of two different data repetitions 230, UE 115-b may combine the LLR vectors using combining coefficients such that α LLR D1 +(1-α)LLR D2In some cases, the network entity 105-a or the UE 115-a may configure the value of the combining coefficient α through SRS training. In some other cases, the UE 115-a and the network entity may negotiate the value of the combining coefficient α based on previous communications (e.g., PDSCH communications previously received on the same QCL beam, CSI measurements, SRS measurements, or any combination thereof).

[0128] In such examples described herein, first demodulator 220-a and second demodulator 220-b may operate concurrently. However, operating demodulators 220 concurrently may result in high power consumption levels for UE 115-a. In situations where UE 115-a may be a low-power device, running demodulators 220 concurrently may consume too much power to prevent UE 115-a from successfully decoding data repetitions 230. Thus, in some cases, UE 115-a may operate demodulators 220 sequentially to reduce power consumption at UE 115-a and utilize a cyclic redundancy check (CRC)-based combination.

[0129] When operating the demodulators 220 sequentially, the UE 115-a may receive the data repetitions 230-a via the first set of antenna elements 250-a, and the UE 115-a may demodulate the data repetitions at a first time using the first demodulator 220-a. The UE 115-a may also receive the data repetitions 230-b via the second set of antenna elements 250-b while receiving the data repetitions 230-a, and the UE 115-a may demodulate the data repetitions 230-b at a second time using the second demodulator 220-b. In some cases, if the UE 115-a transmits SRS measurements for the beamforming configuration using the first set of antenna elements 250-a, the network entity 105-a may configure the beamforming configuration parameters based on the SRS measurements from the first set of antenna elements 250-a. In this manner, the network entity 105-a may select the MCS, PMI, rank indicator (RI), and other transmission parameters based on the SRS measurements from the first set of antenna elements 250-a. In such an example, the second set of antenna elements 250-a may avoid transmitting SRS measurements because transmitting parameters may cause the network entity 105-a to have configured the parameters using SRS measurements from the first set of antenna elements 250-a. As a result, the beamforming configuration between the UE 115-a and the network entity 105-a may be based on the first set of antenna elements 250-a rather than the second set of antenna elements 250-b. As such, the first set of antenna elements 250-a may be referred to as the sounded receive antenna elements 250, while the second set of antenna elements 250-a may be referred to as the unsound receive antenna elements 250.

[0130] In such a case, the UE 115-a may, at a first time, run the first demodulator 220-a on the data repetitions 230-a received via the first set of antenna elements 250-a (e.g., the detected receive antenna elements 250), and run the decoder 215 on the data repetitions 230-a. The UE 115-a may run a CRC on the decoded data repetitions 230-a, and if the CRC passes, the UE 115-a may send an ACK via the feedback message 235. The CRC may be a technique for checking for errors in the decoded data repetitions 230. For example, the data repetitions may have a set of check bits appended to the end of the data, and the UE 115-a may check the check bits for errors to determine if the CRC failed. If the CRC fails (e.g., there is an error in one or more of the parity bits of data repetition 230-a), UE 115-a may run a second demodulator 220-b on data repetition 230-b received via a second set of antenna elements 250-b (e.g., undetected receive antenna elements 250) at a second time and run decoder 215 on data repetition 230-b. UE 115-a may run a CRC on the decoded data repetition 230-b, and if the CRC passes, UE 115-a may send an ACK via feedback message 235. If the CRC fails, UE 115-a may combine data repetition 230-a and data repetition 230-b at a third time. In some cases, UE 115-a may combine decoded data repetition 230-a and decoded data repetition 230-b, both of which initially failed the CRC, and check the CRC without running decoder 215 additional times, thereby saving processing power.

[0131] In some other cases, UE 115-a may run decoder 215 for a certain number of iterations and perform a CRC on combined decoded data repetition 230. In some examples, UE 115-a may run decoder 215 for a reduced number of iterations because UE 115-a previously (e.g., at a first time and a second time) decoded two data repetitions 230. Additionally or alternatively, UE 115-a may ignore decoded data repetition 230, combine initial (e.g., undecoded) data repetition 230-a and initial data repetition 230-b, run a decoder on the combined data repetition 230, and perform a CRC. In such cases, if the CRC fails on the combined data repetition 230, UE 115-a may send a NACK via feedback message 235 indicating a failure to decode data repetition 230.

[0132] Combining data repetitions 230 prior to decoding, or decoding using a decoding order as indicated via auxiliary information 225, may reduce complexity and power consumption for UE 115-a when decoding at data repetitions 230. For example, using such techniques as described herein may reduce complexity and power consumption in operating decoder 215 because UE 115-a may run decoder 215 on the combined data repetitions 230 rather than running decoder 215 on the individual and combined data repetitions 230. Additionally or alternatively, combining data repetitions 230 or decoding using a decoding order as indicated via auxiliary information 225 may reduce latency and delay in decoding data repetitions 230. Techniques for sending and receiving auxiliary information 225 and decoding data repetitions 230 may be described elsewhere herein, including with reference to FIG. Figure 3 ) is described in further detail.

[0133] Figure 3 An example of a process flow 300 for supporting network entity-assisted decoding for repetition-based transmission according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 300 may implement or be implemented by the wireless communication system 100 and / or 200. For example, the process flow 300 may include a UE 115-b and a network entity 105-b, which may represent examples of corresponding devices described herein.

[0134] In the following description of process flow 300, operations between UE 115-b and network entity 105-b may be performed in a different order or at different times. Some operations may also be excluded from process flow 300, or other operations may be added. Although UE 115-b and network entity 105-b are shown as performing the operations of process flow 300, some aspects of some operations may also be performed by one or more other wireless devices. For example, the operations may also be performed by two UEs or any other wireless devices for sidelink communication.

[0135] At 305, UE 115-b may receive a message from network entity 105-b indicating assistance information for UE 115-b to decode a first set of repetitions of a data transmission. The assistance information may include a decoding order for the first set of repetitions, an iteration instruction indicating a number of decoder iterations to run on the first set of repetitions, or both. In some cases, UE 115-b may also receive an indication of a threshold number of repetitions via the assistance information from network entity 105-b. One or more repetitions in the first set of repetitions may include the threshold number of repetitions. Additionally or alternatively, UE 115-b may receive an indication of an index value for decoding one or more repetitions of the data transmission via the assistance information from network entity 105-b. In some examples, the index value may be based on the time-frequency resource location of the one or more repetitions or a repetition index of the first set of repetitions. The index value may point to a particular repetition in the first set of repetitions and indicate that UE 115-b should decode the first set of repetitions starting from the index value. In some other cases, UE 115-b may receive an indication of the RV mode and the RV sequence of the decoding order via assistance information from network entity 105-b.In some examples, UE 115-a may receive one or more repetitions according to the RV sequence.

[0136] In some cases, UE 115-b may receive assistance information from network entity 105-b based on a power change or a state change (e.g., a TCI state change) at network entity 105-b. The assistance information may instruct UE 115-b to run the decoder for a threshold number of iterations on one or more repetitions and combine the LLRs with the remaining one or more repetitions.

[0137] In some examples, the assistance information may be based on a priority of data transmission, a QoS of data transmission, a latency of data transmission, or any combination thereof. That is, the assistance information may indicate a decoding order or decoder iteration instructions based on the priority, QoS, or latency of data transmission. In some cases, the message indicating the assistance information may be dedicated to the decoding order, the decoder iteration instructions, or both. In some other cases, in conjunction with the message indicating the assistance information from network entity 105-b, the message may also schedule downlink shared channel repetitions (e.g., PDSCH repetitions).

[0138] At 310, UE 115-b may monitor one or more repetitions in the first set of repetitions. At 315, network entity 105-b may send one or more repetitions in the first set of repetitions to UE 115-b. In some cases, the repetitions may be repetitions of data transmissions, transport blocks, or some other information. Additionally or alternatively, UE 115-b may receive the one or more repetitions from network entity 105-b via PDCCH, PDSCH, or any other type of downlink channel. In some cases, UE 115-b may receive a message from a wireless communication system (e.g., a wireless communication system such as a wireless communication system). Figure 1 – Figure 2 In some examples, UE 115-b may receive one or more repetitions of one or more TRPs of wireless communication system 100 or wireless communication system 200 described in detail above. In some examples, UE 115-b may receive one or more repetitions from network entity 105-b or one or more TRPs on one or more groups of antenna elements of an antenna panel at UE 115-b. In such examples, UE 115-b may receive a single data transmission via the antenna panel, and the one or more groups of antenna elements may each receive a data transmission. In some cases, UE 115-b may interpret the one or more groups of antenna elements receiving the single data transmission as one or more repetitions of the data transmission.

[0139] At 320, UE 115-b may decode one or more data repetitions in the first set of data repetitions based on the assistance information from network entity 105-b at 305. In some examples, UE 115-b may decode the one or more repetitions after receiving a threshold number of repetitions. In some cases, UE 115-b may decode the one or more repetitions starting from an index value received via the assistance information at 305. In some other cases, UE 115-b may decode the one or more repetitions according to an RV pattern and a decoding order received via the assistance information at 305. Additionally or alternatively, UE 115-b may decode the one or more repetitions according to a decoder iteration instruction. For example, UE 115-b may iterate the decoder over the one or more repetitions as instructed via the decoder iteration instruction.

[0140] In some examples, UE 115-b may selectively combine corresponding LLRs of one or more repetitions. UE 115-b may combine the LLRs based on a first comparison of the LLRs associated with the one or more repetitions, a second comparison of the LLRs associated with the one or more repetitions and a parameter, or both. For example, the first comparison may be whether the LLRs are of the same sign, and the second comparison may be whether the ratio of the absolute values ​​of the LLRs is greater than, equal to, or less than a parameter (e.g., a threshold parameter). Based on the first comparison and the second comparison, UE 115-b may determine whether to combine the LLRs of the one or more repetitions. In some cases, UE 115-b may determine coefficients for combining the corresponding LLRs associated with the one or more repetitions. The coefficients may be determined based on a previous data transmission on the same beam as the data transmission, a CSI report or CSI measurement, an SRS measurement, or any combination thereof. In this manner, UE 115-b may decode the one or more repetitions based on combining the corresponding LLRs and the coefficients.

[0141] In some examples, UE 115-b may demodulate a repetition of one or more repetitions via a first demodulator to obtain a first demodulated signal for the data transmission and a first LLR for the repetition. UE 115-b may then demodulate the repetition via a second demodulator based on a first CRC of the first demodulated signal to obtain a second demodulated signal for the data transmission and a second LLR for the repetition. For example, if the CRC fails on the first demodulated signal, UE 115-b may demodulate the repetition at the second demodulator. Based on the second CRC (e.g., the second CRC fails), UE 115-b may combine the first LLR and the second LLR. Thus, decoding the one or more repetitions may be based on demodulating the repetitions at the first demodulator, the second demodulator, or combining the first LLR and the second LLR. In some examples, UE 115-b may combine the first LLR and the second LLR from the first demodulated signal and the second demodulated signal, respectively, and avoid decoding the combined repetition. In some other examples, UE 115-b may decode the repetitions including the combination of the first LLR and the second LLR, or UE 115-b may combine the repetitions before demodulating the repetitions. In some cases, UE 115-b may avoid demodulating the repetitions at the second demodulator and avoid combining the first LLR and the second LLR based on successful demodulation of the repetitions at the first demodulator. In some other cases, UE 115-b may avoid combining the first LLR and the second LLR based on successful demodulation of the repetitions at the second demodulator.

[0142] In some cases, UE 115-a may send a CSI report to network entity 105-b based on combining a second set of repetitions according to at least one decoder iteration of the repetitions in the second set of repetitions. In some examples, the second set of repetitions may be associated with a first set of transmit parameters. UE 115-b may receive a second set of transmit parameters from network entity 105, and the second set of transmit parameters may be repeatedly associated with the first set. In some examples, UE 115-b may decode one or more repetitions in the first set of repetitions according to the second set of transmit parameters. The first set of transmit parameters and the second set of transmit parameters may include an MCS, a rank parameter, a power control parameter, a beamforming parameter, a TRP panel parameter, a number of repetitions, or any combination thereof.

[0143] At 325, UE 115-b may send a feedback message to network entity 105-b based on decoding one or more repetitions in the first set of repetitions or iterating the decoder for one or more repetitions according to the assistance information received from network entity 105-b at 305. In some cases, the feedback message may indicate successful demodulation of a repetition of the one or more repetitions at the first demodulator or the second demodulator. In some other cases, the feedback message may indicate successful demodulation of a repetition of the one or more repetitions based on a third CRC check associated with the combined first LLR and second LLR passing. In some examples, the feedback message may indicate failed demodulation of a repetition of the one or more repetitions based on a third CRC check failure associated with the combined first LLR and second LLR failing. In this manner, the feedback message may indicate to network entity 105-b whether UE 115-a has successfully decoded the repetition from network entity 105-b based on the assistance information from network entity 105-b.

[0144] Figure 4 A block diagram 400 illustrates a device 405 that supports network entity assisted decoding for repetition-based transmission according to one or more aspects of the present disclosure.

[0152] By including or configuring a communication manager 420 according to examples as described herein, the device 405 (e.g., a processor controlling or otherwise coupled with the receiver 410, the transmitter 415, the communication manager 420, or a combination thereof) may support techniques for a UE to receive auxiliary information for decoding one or more repetitions, which may provide reduced processing, reduced power consumption, and more efficient utilization of communication resources.

[0153] Figure 5 A block diagram 500 illustrates a device 505 that supports network entity assisted decoding for repetition-based transmission according to one or more aspects of the present disclosure.

[0158] Figure 6Block diagram 600 illustrates a communication manager 620 that supports network entity assisted decoding for repetition-based transmissions in accordance with one or more aspects of the present disclosure. Communication manager 620 may be an example of aspects of communication manager 420, communication manager 520, or both, as described herein. Communication manager 620 or its various components may be examples of means for performing various aspects of network entity assisted decoding for repetition-based transmissions as described herein. For example, communication manager 620 may include an assistance information component 625, a repetition component 630, a feedback component 635, an indexing component 640, an RV component 645, a CSI component 650, an LLR component 655, or any combination thereof. Each of these components may communicate directly or indirectly with one another (e.g., via one or more buses).

[0159] The assistance information component 625 can be configured to or otherwise support means for receiving a message indicating a decoding order for the UE to decode a first set of multiple repetitions of the data transmission, an iteration instruction indicating a number of iterations to be performed on the first set of multiple repetitions, or a combination thereof.

[0162] In some examples, RV component 645 can be configured or otherwise support means for receiving an indication of an RV sequence corresponding to an RV mode and a decoding order, wherein one or more repetitions are received according to the RV sequence. In some examples, repetition component 630 can be configured or otherwise support means for decoding the one or more repetitions according to the RV mode and the decoding order.

[0163] In some examples, to support receiving the message, the assistance information component 625 may be configured to or otherwise support means for receiving an indication for the UE to perform a threshold number of iterations on one or more repetitions and combine the iterations with LLRs of remaining repetitions in the one or more repetitions based on at least one of a power change or a state change at the network entity, wherein decoding the one or more repetitions is in accordance with the indication, the iteration instruction including the indication.

[0164] In some examples, to support receiving the message, CSI component 650 can be configured to or otherwise support means for transmitting a CSI report based on combining a second set of multiple repetitions according to at least one decoder iteration of a repetition in the second set of multiple repetitions, wherein the second set of multiple repetitions is associated with a first set of transmission parameters. In some examples, to support receiving the message, repetition component 630 can be configured to or otherwise support means for receiving a second set of transmission parameters associated with the first set of multiple repetitions, wherein decoding one or more repetitions in the first set of multiple repetitions is according to the second set of transmission parameters.

[0166] In some examples, the decoding order is based on a priority of the data transmission, a quality of service of the data transmission, a latency of the data transmission, or any combination thereof.

[0167] In some examples, the message schedules downlink shared channel repetition.

[0168] In some examples, the messages are specific to decode order, iteration instructions, or both.

[0169] In some examples, LLR component 655 can be configured to or otherwise support means for selectively combining respective LLRs associated with one or more repetitions based on a first comparison between the respective LLRs associated with the one or more repetitions, a second comparison between a ratio of the respective LLRs and a parameter, or both, wherein decoding the one or more repetitions is based on the selective combination of the respective LLRs.

A processing system may generally refer to a system or series of machines or components that receives inputs and processes those inputs to produce a set of outputs (which may be passed to other systems or components of the device 1105, for example). For example, the processing system of the device 1105 may refer to a system that includes various other components or subcomponents of the device 1105, such as the processor 1135, or the transceiver 1110, or the communication manager 1120, or other components or combinations of components of the device 1105. The processing system of device 1105 can interface with other components of device 1105 and can process information (such as input or signals) received from other components or output information to other components. For example, the chip or modem of device 1105 may include a processing system and one or more interfaces for outputting information or for obtaining information, or both. The one or more interfaces may be implemented as or otherwise include a first interface configured to output information and a second interface configured to obtain information, or the same interface configured to output information and obtain information, among other specific implementations. In some specific implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a transmitter, so that device 1105 can transmit information output from the chip or modem.Additionally or alternatively, in some implementations, the one or more interfaces may refer to an interface between a processing system of a chip or modem and a receiver, such that the device 1105 can obtain information or signal input and the information can be transmitted to the processing system. A person skilled in the art will readily recognize that the first interface can also obtain information or signal input, and the second interface can also output information or signal output.

[0218] In some examples, bus 1140 may support communications for protocol layers of a protocol stack (e.g., within a protocol layer). In some examples, bus 1140 may support communications associated with logical channels of a protocol stack (e.g., between protocol layers of a protocol stack), which may include communications performed within components of device 1105 or between different components of device 1105 that may be co-located or located in different locations (e.g., where device 1105 may refer to a system in which one or more of communication manager 1120, transceiver 1110, memory 1125, code 1130, and processor 1135 may be located in one of the different components or divided between the different components).

[0219] In some examples, communications manager 1120 can manage aspects of communications with core network 130 (e.g., via one or more wired or wireless backhaul links). For example, communications manager 1120 can manage the delivery of data communications for client devices, such as one or more UEs 115. In some examples, communications manager 1120 can manage communications with other network entities 105 and can include a controller or scheduler for coordinating with other network entities 105 to control communications with UEs 115. In some examples, communications manager 1120 can support an X2 interface within LTE / LTE-A wireless communication network technology to provide communications between network entities 105.

[0220] According to examples disclosed herein, the communication manager 1120 can support wireless communications at a network entity. For example, the communication manager 1120 can be configured to or otherwise support means for sending a message indicating a decoding order for a UE to decode a first set of multiple repetitions of a data transmission, an iteration instruction indicating a number of iterations to be performed on the first set of multiple repetitions, or a combination thereof.
