In a rate partitioning method, messages sent to individual user equipments (UEs) may be partitioned into a common portion and a dedicated portion. The common portion of each message may be sent to a plurality of UEs, and each of the dedicated portions may be sent to each UE such that each UE may receive its complete respective message. The network may assign different feedback resources for the common portion and the dedicated portion of the rate split transmission. The feedback resource for the common portion may be prior to the feedback resource for the dedicated portion.

Technical Field

[0003] The following relates to wireless communication, including priority and feedback for rate - split schemes. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and so on. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi - access systems include fourth - generation (4G) systems (such as Long - Term Evolution (LTE) systems, LTE - Advanced (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 multi - 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). Summary of the Invention

For example, the described techniques provide feedback resources for rate - split transmission. As another example, the described techniques provide rate - split in an initial access message. In rate - split technology, messages sent to each User Equipment (UE) may be split into a common part and a dedicated part. This common part of these messages may be combined in a single common codeword (CW) and sent to multiple UEs, and each dedicated part in the dedicated part may be separately retained in a corresponding dedicated CW and sent to the respective UEs, such that each UE can receive its complete corresponding message. The network may assign different feedback resources for the common part and the dedicated part of rate - split transmission. The feedback resource for the common part may be before the feedback resource for the dedicated part.

[0054] In some wireless communication systems, rate splitting techniques can be used to improve the characteristics of broadcast channels, including the degrees of freedom and capacity of wireless channels. In such methods, messages sent to each user equipment (UE) can be split into a "common" part and a "private" part. The common part of the messages for each UE can be combined in a single common codeword (CW), and each private part in the private part can be separately retained in a corresponding private CW (e.g., on a per-UE basis). The common CW can be sent to multiple UEs, and each private CW can be sent to each UE separately, such that each UE can receive the complete corresponding message for that UE as a combination of the common CW and the private CW. To decode the private part, the UE can first decode the common part. The time period during which the UE processes the downlink message received via the physical downlink shared channel (PDSCH) before sending feedback can be referred to as the PDSCH processing time. The UE can start sending feedback from at least the first symbol of the PDSCH processing time after the last symbol of the PDSCH. In rate splitting, since decoding the sent private part may depend on decoding the sent common part, the PDSCH processing time for the sent common part may be less than the PDSCH processing time for the sent private part.

[0055] In some examples, the network entity can assign different hybrid automatic repeat request (HARQ) acknowledgment (ACK) resources for the common part and the private part sent by rate splitting. In some examples, the HARQ-ACK resources for the common part can be before the HARQ-ACK resources for the private part. In some examples, the UE can report the PDSCH processing time for the common part and the PDSCH processing time for the private part, and the network entity can configure the HARQ-ACK resources for the common part and the private part based on the reported PDSCH processing times. In some examples, the network can assign a higher priority to the HARQ-ACK for the common part than the HARQ-ACK for the private part, because the private part may not be decoded unless the common part is decoded. For example, if the first resource for the HARQ-ACK for the common part is lost or discarded (e.g., due to a scheduling conflict with another physical uplink control channel (PUCCH) transmission), the UE can send the HARQ-ACK for the common part on the HARQ-ACK resources for the private part. In some examples, the UE can discard the HARQ-ACK for the private part. In some examples, the UE can reuse the HARQ-ACK for the common part and the private part.

[0056] In some examples, rate splitting may be used in an initial access message (e.g., a random access channel (RACH) message). A network entity may indicate in control signaling (e.g., a master information block (MIB) or a system information block (SIB)) or in one of the RACH messages in the RACH messages which subsequent RACH messages will be sent using a rate splitting scheme. The control signaling may indicate the number of layers associated with each rate split message and the modulation and coding scheme (MCS). The UE may accordingly decode the indicated rate split RACH messages.

[0057] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated with reference to resource diagrams, slot formats, and process flows. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flowcharts related to priorities and feedback for rate splitting schemes.

[0058] Figure 1 An example of a wireless communication system 100 that supports priorities and feedback for rate splitting schemes in accordance with 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.

[0059] The network entities 105 may be dispersed throughout a geographical area to form the wireless communication system 100 and may include devices in different forms or having 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 names. 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 entity 105 may support a coverage area 110 (e.g., a geographical coverage area) within which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographical area within which the network entity 105 and the UEs 115 may support signal communication according to one or more radio access technologies (RATs).

[0060] UE 115 can be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile or stationary and mobile at different times. The UE 115 can be a device in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated therein. The UEs 115 described herein can be capable of supporting communication with various types of devices (such as other UEs 115 or network entities 105 as Figure 1 shown).

[0061] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) can be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, a device, an equipment, 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 can be a UE 115. As another example, the node can be a network entity 105. As yet another example, a first node can be configured to communicate with a second node or a third node. In one aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a UE 115. In another aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a network entity 105. In other aspects of this example, the first node, the second node, and the third node can be different from these examples. Similarly, references to UEs 115, network entities 105, devices, equipment, computing systems, etc. can include the disclosure of UEs 115, network entities 105, devices, equipment, computing systems, etc. as nodes. For example, the disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.

[0062] In some examples, network entity 105 may communicate with core network 130 or with each other or both. For example, network entity 105 may 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 entity 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical link, fiber optic link), one or more wireless links (e.g., radio link, wireless optical link), and so on or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155.

[0063] One or more of the network entities 105 described herein may include or may be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, Node B, evolved Node B (eNB), next generation Node B or giga Node B (any of which may be referred to as gNB), 5G NB, next generation eNB (ng-eNB), home Node B, home evolved Node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140). Components within a wireless communication system may be coupled to each other (e.g., operatively coupled, communicatively coupled, functionally coupled, electronically coupled, and / or electrically coupled).

[0064] In some examples, network entity 105 may be implemented in a split architecture (e.g., split base station architecture, split RAN architecture), which may be configured to utilize a protocol stack 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, network entity 105 may 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, an intelligent radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of network entity 105 in the split RAN architecture may be co-located, or one or more components of 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 split RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0065] The functional split between the CU 160, DU 165, and RU 170 is flexible and can support different functions, depending on which functions are performed at the CU 160, DU 165, or RU 170 (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof). For example, a functional split of the protocol stack can be employed between the CU 160 and DU 165 such that the CU 160 can support one or more layers of the protocol stack and the DU 165 can support one or more different layers of the protocol stack. In some examples, the CU 160 can host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functions and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 can be connected to one or more DU 165s or RU 170s, and one or more DU 165s or RU 170s can host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, media access control (MAC) layer) functions and signaling, and can each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack can be employed between the DU 165 and RU 170 such that the DU 165 can support one or more layers of the protocol stack and the RU 170 can support one or more different layers of the protocol stack. The DU 165 can support one or more different cells (e.g., via one or more RU 170s). In some cases, the functional split between the CU 160 and DU 165 or between the DU 165 and RU 170 can be within a protocol layer (e.g., some functions of a protocol layer can be performed by one of the CU 160, DU 165, or RU 170, while other functions of that protocol layer are performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 can be further functionally split into a CU control plane (CU-CP) and a CU user plane (CU-UP) function. The CU 160 can be connected to one or more DU 165s via an intermediate transport communication link 162 (e.g., F1, F1-c, F1-u), and the DU 165 can be connected to one or more RU 170s via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the intermediate transport communication link 162 or the fronthaul communication link 168 can be implemented according to the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the respective network entities 105 communicating via such communication links.

[0066] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to a core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. 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 the 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 a separate antenna set for relaying communication with the UE 115, or may share the same antenna (e.g., of the RU 170 of the IAB node 104) 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 nodes 104, UEs 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the disaggregated 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.

[0067] For example, the access network (AN) or RAN may include communication between an access node (e.g., an IAB donor), an IAB node 104, and one or more UEs 115. The IAB donor may facilitate the connection 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 having 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 a RU 170), where 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 an F1 interface according to a protocol that defines signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, the CU 160 may communicate with the core network via an interface (which may be an example of a part of the backhaul link), and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB hosts) via an Xn-C interface (which may be an example of a part of the backhaul link).

[0068] The IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node towards a child node associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards a parent node associated with the IAB node 104. That is, the 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 a UE 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 a child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and a DU interface (e.g., DU 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or a UE 115.

[0069] For example, the IAB node 104 may be referred to as a parent node supporting communication for the sub-IAB nodes or as a sub-node associated with the 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., a fronthaul communication link 120) and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to the UE 115 via the IAB node 104, or may signal transmissions directly to the UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling over the NR Uu interface to the MT of the IAB node 104. Communication with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communication with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104.

[0070] In the case where the techniques described herein are applied in the context of a split RAN architecture, one or more components of the split RAN architecture may be configured to support priorities and feedback for rate splitting schemes as described herein. For example, some operations described as being performed by the UE 115 or the network entity 105 (e.g., the base station 140) may additionally or alternatively be performed by one or more components of the split RAN architecture (e.g., the IAB node 104, the DU 165, the CU 160, the RU 170, the RIC 175, the SMO 180).

[0071] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as: a cellular phone, personal digital assistant (PDA), multimedia / entertainment device (e.g., radio, MP3 player, video device), camera, gaming device, navigation / location device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), Beidou, GLONASS, or Galileo, ground-based devices, etc.), tablet computer, laptop computer, personal computer, netbook, smartbook, personal computer, smart device, wearable device (e.g., smartwatch, smart clothing, smart glasses, virtual reality goggles, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), drone, robot / robotic device, vehicle, in-vehicle device, meter (e.g., parking meter, electricity meter, gas meter, water meter), monitor, air pump, electrical appliance (e.g., kitchen appliance, washing machine, dryer), location tag, medical / health device, implant, sensor / actuator, display, or any other suitable device configured to communicate via wireless or wired media. In some examples, the UE 115 may include or may be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances, vehicles, meters, etc.

[0072] The UE 115 described herein may be capable of communicating with various types of devices such as other UE 115s that may sometimes act as relays, as well as network entity 105 and network equipment including macro eNB or gNB, small cell eNB or gNB, or relay base stations, etc., as Figure 1 shown.

[0073] The UE 115 and the network entity 105 may communicate wirelessly 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" may refer to a set of RF spectrum resources having a physical layer structure defined to support the communication link 125. For example, a carrier for the communication link 125 may include a portion (e.g., bandwidth part (BWP)) of an RF spectrum band operating 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 may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may 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 these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "transmit," "receive," or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 of the RAN (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0074] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling for coordinating the operation of other carriers. A carrier may be associated with a frequency channel (e.g., evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN)) and may be identified according to a channel raster for discovery by the UE 115. A carrier may operate in an independent mode, in which case initial acquisition and connection may be performed by the UE 115 via the carrier, or the carrier may operate in a non-independent mode, in which case the connection is anchored using a different carrier (e.g., different carriers of the same or different radio access technologies).

[0075] The communication link 125 shown in the wireless communication system 100 may include other transmission configurations such as a downlink transmission (e.g., forward link transmission) from the network entity 105 to the UE 115, an uplink transmission (e.g., return link transmission) from the UE 115 to the network entity 105, or both. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink communication and uplink communication (e.g., in TDD mode).

[0076] A carrier can be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth can be one of the bandwidths in a set of bandwidths of carriers of a specific radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., the network entity 105, the UE 115, or both) can have a hardware configuration that supports communication using a specific carrier bandwidth, or may be configurable to support communication using one of the carrier bandwidths in a set of carrier bandwidths. In some examples, the wireless communication system 100 can 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 can be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0077] The signal waveform transmitted via a carrier can include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing an MCM technique, a resource element can refer to the resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing can be inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively large number of resource elements (e.g., in the transmission duration) and a relatively high-order modulation scheme can correspond to a relatively high communication rate. Wireless communication resources can refer to a combination of RF spectrum resources, time resources, and space resources (e.g., spatial layers or beams), and the use of multiple space resources can increase the data rate or data integrity for communication with the UE 115.

[0078] One or more parameter sets can be supported for a carrier, and the parameter set can include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, the UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and the communication of the UE 115 can be restricted to one or more active BWPs.

[0079] The time interval for the network entity 105 or the UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can, for example, refer to the sampling period T s = 1 / (Δf max ·Nf ) seconds, for which Δf max can represent the supported subcarrier spacing, and N f can represent the supported discrete Fourier transform (DFT) size. The time intervals of the communication resources can be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0080] Each frame can include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot can have the same duration. In some examples, a frame can be divided (e.g., in the time domain) into subframes, and each subframe can be further divided into a certain number of time slots. Alternatively, each frame can include a variable number of time slots, and the number of time slots can depend on the subcarrier spacing. Each time slot can include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, a time slot can be further divided into a plurality of mini - slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period can be associated with one or more (e.g., N f ones) sampling periods. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0081] A subframe, time slot, mini - slot, or symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0082] According to various techniques, carriers can be used to multiplex physical channels for communication. For example, one or more of time-division multiplexing (TDM) techniques, frequency-division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region of a physical control channel (e.g., a control resource set (CORESET)) can be defined by a set of symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search a control region for control information according to one or more search space sets, and each search space set can 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 can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format with a given payload size. The search space set can include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set for transmitting control information to a specific UE 115.

[0083] The network entity 105 can 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" can refer to a logical communication entity for communicating with the network entity 105 (e.g., using a carrier) and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier) for distinguishing adjacent cells. In some examples, a cell can also refer to the coverage area 110 or a part of the 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, the scope of such cells can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or can include a building, a subset of a building, or an external space between or overlapping the coverage areas 110, etc.

[0084] Macro cells generally cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access to UEs 115 that have a service subscription with the network provider that supports the macro cell. Compared to macro cells, small cells can be associated with a lower power network entity 105 (e.g., a lower power base station 140), and small cells can operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UEs 115 that have a service subscription with the network provider, or can provide restricted access to UEs 115 that are 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). The network entity 105 can support one or more cells and can also use one or more component carriers to support communication via one or more cells.

[0085] In some examples, a carrier can support multiple cells and can be configured with different cells according to different protocol types that can provide access for different types of devices (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)).

[0086] In some examples, the network entity 105 (e.g., base station 140, RU 170) can be movable and thus provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies can overlap, but 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 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0087] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) can have similar frame timings, and transmissions from different network entities 105 can be approximately aligned in time. For asynchronous operation, the network entities 105 can have different frame timings, and in some examples, transmissions from different network entities 105 can be misaligned in time. The techniques described herein can be used for synchronous operation or asynchronous operation.

[0088] Some UEs 115 (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or obtain information and relay such information to a central server or application that uses the information or presents the information to a person interacting with the application. Some UEs 115 can be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geographical event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging. In one aspect, the techniques disclosed herein can be applicable to MTC or IoT UEs. MTC or IoT UEs can include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. eMTC and NB-IoT can refer to future technologies that can evolve from or be based on these technologies. For example, eMTC can include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), and mMTC (massive MTC), while NB-IoT can include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0089] Some UEs 115 can be configured to operate in an operation mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication can be performed at a reduced peak rate. Other energy-saving technologies for UEs 115 include: entering a power-saving deep sleep mode when not participating in active communication, operating using limited bandwidth (e.g., according to narrowband communication), or a combination of these technologies. For example, some UEs 115 can be configured to operate using a narrowband protocol type associated with a defined portion or range within a carrier, within a guard band of the carrier, or outside the carrier (e.g., a set of subcarriers or resource blocks (RBs)).

[0090] 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 communication or group communication 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 can be used interchangeably herein.

[0091] In some examples, the UE 115 can be configured to communicate 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 performing D2D communication in a group can be within the coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), and the network entity can support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. 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, where each UE 115 sends to each of the other UEs 115 in the group. In some examples, the network entity 105 can facilitate the scheduling of resources for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving the network entity 105.

[0092] 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 for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of the UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be passed 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. The IP services 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet switched streaming service.

[0093] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or the decimeter band because, in terms of length, the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clutter), but these waves may be sufficient to penetrate structures so that macro cells can provide service to UEs 115 located indoors. Compared to communications using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers).

[0094] The wireless communication system 100 may also operate using the super high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or using the extremely high frequency (EHF) region of the spectrum (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) communication between the UE 115 and the network entity 105 (e.g., the base station 140, the RU 170), and the EHF antennas of the corresponding devices may be smaller and closer spaced than UHF antennas. In some examples, such technologies may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by greater attenuation and shorter ranges than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands designated across these frequency regions may vary by country or regulatory body.

[0095] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band) to employ licensed-assisted access (LAA), long term evolution unlicensed (LTE-U) radio access technology, or NR technology. When operating using an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, the operation using the unlicensed band may be combined with a component carrier operating using a licensed band based on a carrier aggregation configuration (e.g., LAA). The operation using the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, device-to-device (D2D) transmissions, and so on.

[0096] The network entity 105 (e.g., the base station 140, the RU 170) or the UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some 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 antenna ports arranged in multiple rows and columns that the network entity 105 may use to support beamforming for communication with the UE 115. Similarly, the UE 115 may include one or more antenna arrays, which may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0097] The network entity 105 or the UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques can be referred to as spatial multiplexing. The multiple signals can be, for example, transmitted by the transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same CW) or different data streams (e.g., different CWs). The different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO techniques include: single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0098] Beamforming (which can 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., the network entity 105, the UE 115) to shape or direct 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 the signals conveyed via the antenna elements of an antenna array such that some signals propagating along a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals conveyed via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each of these antenna elements can be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0099] The network entity 105 or the UE 115 can use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., the base station 140, the RU 170) can use multiple antennas or antenna arrays (e.g., an antenna panel) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted by the network entity 105 multiple times in different directions. For example, the network entity 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. The transmissions along different beam directions can be used to identify (e.g., by the transmitting device such as the network entity 105, or by the receiving device such as the UE 115)) the beam directions for subsequent transmission or reception by the network entity 105.

[0100] 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) in a single beam direction (e.g., a direction associated with a receiving device such as receiving network entity 105 or receiving UE 115). In some examples, the beam direction associated with transmission in a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by network entity 105 in different directions and may report to network entity 105 an indication of the signal that UE 115 receives with the highest signal quality or other acceptable signal quality.

[0101] In some examples, transmissions made 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 beam set across the system bandwidth or one or more sub-bands. Network entity 105 may transmit a reference signal (e.g., cell-specific reference signal (CRS), channel state information reference signal (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., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions used by UE 115 for subsequent transmission or reception), or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0102] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a transmitting device (e.g., network entity 105). For example, the receiving device may perform receiving according to multiple receiving directions by: receiving via different antenna sub-arrays, processing the received signals according to different antenna sub-arrays, receiving according to different sets of receive beamforming weights (e.g., different directional listening weight sets) applied to the signals received at multiple antenna elements of an antenna array, or processing the received signals according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receiving configuration may be aligned along a beam direction determined based on listening according to different receiving 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).

[0103] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly for conveyance via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide establishment, configuration, and maintenance of an RRC connection for radio bearers supporting user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map transport channels to physical channels.

[0104] UE 115 and network entity 105 may support retransmission of data to increase the likelihood that the data is successfully received. 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 cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In some other examples, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0105] Wireless communication system 100 may implement rate splitting techniques to improve the characteristics of the broadcast channel, including the degrees of freedom and capacity of the wireless channel. For example, a message for each UE 115 may be split into a "common" part and a "private" part. The common parts of the messages for each UE 115 may be combined in a single common CW, and each private part in the private parts may be separately retained in a corresponding private CW (e.g., on a per-UE basis). The common CW may be sent to multiple UEs 115, and each private CW may be sent separately to each UE 115 such that each UE 115 may receive its complete corresponding message. To decode the private part, UE 115 may first decode the common part. In rate splitting, since decoding the private part may depend on decoding the common part, the PDSCH processing time for the common part may be less than the PDSCH processing time for the private part.

[0106] In some examples, network entity 105 may assign different HARQ-ACK resources for the common part and the dedicated part of rate-split transmission. The HARQ-ACK resources for the common part may be before the HARQ-ACK resources for the dedicated part. In some examples, UE 115 may report the PDSCH processing time for the common part and the PDSCH processing time for the dedicated part, and network entity 105 may configure the HARQ-ACK resources for the common part and the dedicated part based on the reported PDSCH processing times. In some examples, since decoding the dedicated part depends on successfully decoding the common part, network entity 105 may assign a higher priority to the HARQ-ACK for the common part than the HARQ-ACK for the dedicated part. For example, if the first resource for the HARQ-ACK for the common part is lost or discarded (e.g., due to a scheduling conflict with another PUCCH transmission), UE 115 may send the HARQ-ACK for the common part on the HARQ-ACK resource for the dedicated part. In some examples, UE 115 may discard the HARQ-ACK for the dedicated part. In some examples, UE 115 may reuse the HARQ-ACK for the common part and the dedicated part.

[0107] In some examples, rate splitting may be used in an initial access message (e.g., a RACH message). Network entity 105 may indicate in control signaling (e.g., MIB or SIB) or in one of the RACH messages in the RACH message which subsequent RACH messages will be sent using a rate splitting scheme. The control signaling may indicate the number of layers and the MCS associated with each rate-split message. UE 115 may decode the indicated rate-split RACH messages accordingly.

[0108] Figure 2 An example of a wireless communication system 200 supporting priorities and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure is illustrated. Wireless communication system 200 includes network entity 105-a, which may be an example of network entity 105 as described herein with reference to Figure 1 as described. Network entity 105-a may communicate with UE 115-a and UE 115-b, which may be examples of UE 115 as described herein with reference to Figure 1 as described.

[0109] Network entity 105-a may communicate with UEs 115-a and 115-b using rate splitting techniques. For example, network entity 105-a may determine a first message destined for UE 115-a and a second message destined for UE 115-b. Network entity 105-a may split the messages destined for UE 115-a and UE 115-b into a common part to be decoded by both UEs 115-a and 115-b and a dedicated part unique to each of UEs 115-a and 115-b. In some examples, network entity 105-a may use rate splitting techniques for broadcast channels, for example, to achieve relatively high transmission degrees of freedom, relatively high transmission capacities, obtain other advantages, or any combination. In some cases, the common parts of the respective messages of two or more UEs 115 may be combined (e.g., concatenated) into a common part W c which is encoded and modulated to obtain X c which may be referred to as a common stream and may have one or more layers.

[0110] For example, network entity 105-a may perform message splitting for UEs 115-a and 115-b at 210. Network entity 105-a may split the first message destined for UE 115-a into a common part W 1,c and a dedicated part W 1,p . Similarly, network entity 105-a may split the second message destined for UE 115-b into a common part W 2,c and a dedicated part W 2,p .

[0111] At 215, network entity 105-a may combine the common part W 1,c of the first message with the common part W 2,c of the second message to obtain a combined common part W c . At 220, network entity 105-a may encode the combined common part W c , the dedicated part W 1,p of the first message, and the dedicated part W 2,p of the second message to obtain the common stream X c , the dedicated stream X1 for UE 115-a, and the dedicated stream X2 for UE 115-b, respectively.

[0112] At 225, network entity 105-a may pre-decode the common stream X c . In some examples, network entity 105-a may use a pre-decoder P c to pre-decode X cPerform pre - decoding, and network entity 105 - a can determine P based on pre - configured values or otherwise defined values c . Network entity 105 - a can use one or more transmit antennas 230 to transmit the pre - decoded common stream.

[0113] For example, network entity 105 - a can separately encode and modulate the dedicated parts of the respective messages from UE 115 - a and UE 115 - b (e.g., W 1,p and W 2,p ) to obtain the dedicated streams for the corresponding UEs (e.g., X1 and X2). The dedicated streams can be pre - decoded according to different pre - decoders such as P1 and P2. Accordingly, the pre - decoded output X can be given as X = P c X c + P1X1+ P2X2. Network entity 105 - a can use transmit antennas 230 different from those for the common stream to transmit the dedicated streams. In some examples, in addition to encoding, the encoding at 220 can include modulation and mapping to one or more layers.

[0114] Network entity 105 - a can send the pre - decoded transmission H1 to UE 115 - a, which can include the common stream X c , the dedicated stream X1, or both. Similarly, network entity 105 - a can send the pre - decoded transmission H2 to UE 115 - b, which can include the common stream X c , the dedicated stream X2, or both. UE 115 - a can receive the signal Y1, where Y1 = H1P c X c + H1P1X1+ H1P2X2+ N1. Network entity 105 - a can send the common stream and the dedicated streams via the transmission of one or more common transport blocks, dedicated transport blocks, common code blocks, dedicated code blocks, or any combination thereof. For example, network entity 105 - a can send the pre - decoded transmission H1 to UE 115 - a via communication link 235 - a, and can send the pre - decoded transmission H2 to UE 115 - b via communication link 235 - b. Communication link 235 - a and communication link 235 - b can be examples of communication link 125 as described herein Figure 1 .

[0115] UE 115 - a and UE 115 - b can receive the one or more common transport blocks, dedicated transport blocks, common code blocks, dedicated code blocks, or their combination. In some cases, at the receiver side, each UE 115 can, for example, use successive decoding to decode the common part before the dedicated part. In some cases, at the receiver side, each UE 115 can decode the corresponding dedicated part before the common part. In some examples, at 240, UE 115 - a can perform for the common stream Xc and perform channel estimation for dedicated stream X 1,p For example, UE 115-a may estimate the effective channel corresponding to the common stream (e.g., H1P c ). At 245, UE 115-a may decode the common stream X c to obtain the common part (e.g., W c ), which may include the demodulation and demapping processes. The common part may include messages of individual messages for each UE 115 embedded in the common part (e.g., W 1,c and W 2,c ), including data for individual UE 115-a.

[0116] At 250, in order to obtain the dedicated part, UE 115-a may re-encode the common stream (e.g., X c ) and may perform adaptation based on the estimated effective channel (e.g., H1P c ) (e.g., may multiply by the estimated effective channel). At 255, UE 115-a may adapt the result from the received signal Y1 (e.g., may subtract the result from the received signal), which may generate an effective channel Y 1,p for the dedicated part. That is, UE 115-a may perform cancellation according to Equation 1:

[0117] Y 1,p = Y1 - H1P c X c = H1P1X1 + H1P2X2 + N1 (1)

[0118] where N1 is the interference value, and Equation 1 is based on correct channel estimation and successful decoding.

[0119] At 260, UE 115-a may use Y 1,p to decode the dedicated part W 1,p . In addition to decoding, the decoding at 245 and 260 may also include demodulation and demapping. Accordingly, UE 115-a may obtain the entire message W1 based on the common part (e.g., W 1,c ) and the dedicated part (e.g., W 1,p ). UE 115-b may follow a similar process to obtain the common part (e.g., W 2,c ) and the dedicated part (e.g., W 2,p ), which UE 115-b may use to obtain the entire message W2.

[0120] Figure 3Illustrates an example of a resource graph 300 that supports prioritization and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure. The resource graph 300 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0121] The resource graph 300 illustrates an example of uplink control information (UCI) multiplexing and prioritization techniques. In some examples, when a physical uplink control channel (PUCCH) resource (the PUCCH resource includes UCI for hybrid automatic repeat request - acknowledgement (HARQ - ACK), channel state information (CSI), or scheduling request (SR)) overlaps with a physical uplink shared channel (PUSCH) resource, the UE 115 may multiplex the UCI on the PUSCH.

[0122] For example, the resource graph 300 illustrates that a first PUCCH 305 including UCI1 with CSI1 overlaps with a third PUCCH 315 including UCI3 with HARQ - ACK. A second PUCCH 310 including UCI2 with CSI - 2 does not overlap with the first PUCCH 305 or the third PUCCH 315. A fourth PUCCH 320 including UCI4 with SR does not overlap with the first PUCCH 305, the second PUCCH 310, or the third PUCCH 315. A first PUSCH 325 overlaps with the first PUCCH 305 and the third PUCCH 315. A second PUSCH 330 overlaps with the second PUCCH 310.

[0123] In some examples, at step 1, the UE 115 may resolve the overlap of different PUCCH resources (the first PUCCH 305 and the third PUCCH 315) by multiplexing UCI1 and UCI3 at a fifth PUCCH 340 including UCI1 and UCI3 with HARQ - ACK and CSI1. The result of step 1 provides non - overlapping PUCCH resources for the second PUCCH 310, the fourth PUCCH 320, and the fifth PUCCH 340 with UCI (HARQ - ACK, CSI, and SR).

[0124] In some examples, at step 2, UE 115 may resolve overlapping PUSCH and PUCCH. For example, UE 115 may resolve the overlap between the fifth PUCCH 340 and the first PUSCH 325 by multiplexing UCI1 and UCI3 on the first PUSCH 325, thereby forming the first PUSCH+UCI1+UCI3 345. UE 115 may transmit the first PUSCH+UCI1+UCI3 345 and may not transmit the fifth PUCCH 340. Similarly, UE 115 may resolve the overlap between the second PUSCH 330 and the second PUCCH 310 by multiplexing UCI2 on the second PUCCH 310, thereby forming the second PUSCH+UCI2 350. UE 115 may transmit the second PUSCH+UCI2 350 and may not transmit the second PUCCH 310. UE 115 may transmit the fourth PUCCH 320 that does not overlap with any resources. In some examples, the β offset signaled in the uplink grant (downlink control information (DCI) format 0_1 / 0_2) or the configured RRC parameter is used to control the rate matching behavior for multiplexing PUCCH on PUSCH (e.g., the number of resources that the UCI payload on PUSCH can occupy). In some examples, the overlapping PUSCH and PUCCH in step 2 may be on the same component carrier (CC) or different CCs. When it comes to channels with dynamic scheduling (scheduled by DCI), the joint timeline may be satisfied for UCI multiplexing on PUCCH or PUSCH. In some examples, the priority of UCI may be defined as HARQ-ACK > SR > higher priority CSI > lower priority CSI. For overlapping resources or time slots, the UCI with reduced priority may be discarded without any delay to transmission.

[0125] In some examples, the dedicated stream and the common stream or message or transport block (TB) may represent the same priority of the CW and may have the same priority or quality of service (QoS) in the upper layer and the PHY. For rate-split transmission, if UE 115 cannot decode the common part (e.g., negative acknowledgment (NACK)), the UE may not be able to decode the dedicated part. In terms of feedback priority, the HARQ-ACK of the common part may have a higher priority than the HARQ-ACK of the dedicated part. In some examples, the assigned priority of the HARQ-ACK of the common part may be higher than the assigned priority of the HARQ-ACK of the dedicated part. In some examples, the CSI derived based on the common part may have a lower priority than the CSI derived for the dedicated part because the CSI of the dedicated part is UE-specific and is expected to change faster than the CSI of the common part. In some examples, the MCS of the dedicated part is higher than the MCS of the common part, so the dedicated part is expected to have a larger error than the common part. In some examples, obtaining the CSI of the dedicated part may have a higher priority, and if there is a reason to discard the CSI of the dedicated part or the CSI of the common part, the CSI of the dedicated part may not be discarded first.

[0126] In some examples, the HARQ-ACK of the common part may have a higher priority than the HARQ-ACK of the dedicated part. In some examples, the HARQ-ACK of the common part may have the same priority as the HARQ-ACK of the dedicated part. In some examples, as the overall priority of the HARQ-ACK increases, a higher priority may be given to the HARQ-ACK of the common part, and a sub-priority may be defined for the HARQ-ACK of the dedicated part.

[0127] Figure 4 An example of a resource graph 400 that supports priorities and feedback for a rate-split scheme in accordance with one or more aspects of the present disclosure is illustrated. The resource graph 400 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0128] In some examples, the UE 115 may indicate to the network entity 105 the processing capabilities (N1_c) of the UE 115 for preparing HARQ-ACK for the common part of rate-split transmission and the processing capabilities (N1_p) of the UE 115 for preparing HARQ-ACK for the dedicated part of rate-split transmission. In some examples, the UE 115 may report to the network entity 105 the PDSCH processing time for the common part and the PDSCH processing time for the dedicated part, and the network entity 105 may configure the HARQ-ACK resources for the common part and the dedicated part based on the reported PDSCH processing times. Based on the N1_c value and the N1_p value, the network entity 105 may assign an offset time (K1_c) for the HARQ-ACK of the common part and an offset time (K1_p) for the HARQ-ACK of the dedicated part. In some examples, the offset times K1_c and K1_p may be provided from the network entity 105 to the UE 115 in the DCI scheduling rate-split transmission. In some examples, the network entity 105 may define an RRC or MAC control element (MAC-CE) offset that matches the increment between N1_c and N1_p.

[0129] For Figure 4 the example illustrated in, the UE 115 may process the downlink message received via the PDSCH 405. In the illustrated example, K1_c is the time period for the UE 115 to process the common part before sending feedback (e.g., HARQ-ACK) for the downlink common part to the network entity 105. K1_p is the time period for the UE 115 to process the dedicated part before sending feedback (e.g., HARQ-ACK) for the downlink dedicated part to the network entity 105. In some examples, the K1_c processing time for the common part may be less than the K1_p processing time for the dedicated part. In one example, the first PUCCH 410 carries the HARQ-ACK for the common part to the network entity 105, and the second PUCCH 415 carries the HARQ-ACK for the dedicated part to the network entity. The UE 115 may start sending the HARQ-ACK for the common part from the first symbol that is at least K1_c processing time after the last symbol of the PDSCH 405. The UE 115 may start sending the HARQ-ACK for the dedicated part from the first symbol that is at least K1_p processing time after the last symbol of the PDSCH 405.

[0130] In some examples, the network entity 105 may configure two resources for HARQ-ACK of the common part and HARQ-ACK of the dedicated part based on the timing capabilities indicated by the UE 115, such as the first PUCCH 410 and the second PUCCH 415. In some examples, if the HARQ-ACK of the common part is discarded (e.g., due to a scheduling conflict with another PUCCH transmission), the UE 115 may send the HARQ-ACK of the common part on the second PUCCH 415 and may discard the HARQ-ACK of the dedicated part. In some examples, if the HARQ-ACK of the common part is discarded, the UE 115 may jointly send the HARQ-ACK of the common part and the HARQ-ACK of the dedicated part on the second PUCCH 415. In some examples, the joint transmission of the HARQ-ACK of the common part and the HARQ-ACK of the dedicated part may be separately encoded on different resources or jointly encoded on these resources. In another example, to increase reliability in the case where the first PUCCH 410 is missed, the UE 115 may multiplex both the HARQ-ACK of the common part and the HARQ-ACK of the dedicated part on the second PUCCH 415.

[0131] Figure 5 An example of a slot format 500 that supports priorities and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure is illustrated. The slot format 500 may implement aspects of the wireless communication system 100 or the wireless communication system 200.

[0132] In some examples, the network entity 105 may configure two resources for HARQ-ACK of the common part for rate splitting transmission and HARQ-ACK of the dedicated part for rate splitting transmission on slot 505. Slot 505 may include a resource 510 for HARQ-ACK of the common part and a resource 515 for HARQ-ACK of the dedicated part. The network entity 105 may assign time based on the processing capabilities indicated by the UE115 (e.g., max(N1_c,N1_p) or the PDSCH processing time for the common part and the PDSCH processing time for the dedicated part reported by the UE). In some examples, the resource 510 and the resource 515 may be separate (e.g., located in separate symbols of slot 505), and the two bits may be separately encoded. In some examples, the two bits may be multiplexed in the original bits and then encoded using a single CW (e.g., using a single cyclic shift in the case of PUCCH 0 or using a polar encoder).

[0133] Figure 6Illustrates an example of a process flow 600 that supports prioritization and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure. The process flow 600 may include a UE 115-c and a network entity 105-b, which may be examples of the corresponding devices described herein. The processing flow 600 may include aspects of a 4-step RACH process. The network entity 105-b and the UE 115-c may perform the 4-step RACH process. For example, the 4-step RACH may be used by the UE 115-c to access a cell (e.g., establish an RRC connection with the cell of the network entity 105-b). The following replacement examples may be implemented, where some steps may be performed in a different order than described or not performed at all. In some embodiments, the steps may include additional features not mentioned below, or other steps may be added.

[0134] At 605, the network entity 105-b may transmit a synchronization signal block (SSB), which may be received by the UE 115-c. The SSB may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and / or a physical broadcast channel (PBCH). At 610, the network entity 105-b may transmit a system information block (SIB) via a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH), which may be received by the UE 115-c. At 615, the UE 115-c may transmit a msg1 including a physical random access channel (PRACH) preamble to the network entity 105-b via the PRACH. At 620, the network entity 105-b may transmit a msg2 including a timing advance, an uplink grant for msg3, and / or a temporary cell radio network temporary identifier (TC-RNTI) to the UE 115-c via the PDCCH or the PDSCH. At 625, the UE 115-c may transmit a msg3 including an RRC connection request, a scheduling request, and a buffer status to the network entity 105-b via a physical uplink shared channel (PUSCH). At 630, the network entity 105-b may transmit a msg4 including a content parsing message to the UE 115-c via the PDCCH or the PDSCH.

[0135] Figure 7An example of a process flow 700 that supports prioritization and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure is illustrated. The process flow 700 may include a UE 115-d and a network entity 105-c, which may be examples of the corresponding devices described herein. The processing flow 700 may include aspects of a two-step RACH process. The network entity 105-c and the UE 115-d may perform the two-step RACH process. For example, the two-step RACH process may be used by the UE 115-d to transition from the RRC idle or RRC inactive state to the RRC connected state, thus for small data transmission when in the RRC idle or inactive state, for handover from a source cell to a target cell in the RRC connected mode, or for the UE 115-d to recover from uplink synchronization loss when in the RRC connected mode. The following alternative examples may be implemented, where some steps may be performed in a different order than described or not performed at all. In some embodiments, the steps may include additional features not mentioned below, or other steps may be added.

[0136] At 705, the network entity 105-c may transmit an SSB, SIB, reference signal (RS), and / or RRC signaling, which may be received by the UE 115-d. At 710, the UE 115-d may perform downlink synchronization and / or perform system information (SI) decoding and measurements based on the signaling received at 705. At 715, the UE 115-c may transmit a msgA preamble to the network entity 105-c on the PRACH. At 720, the UE 115-d may transmit a msgA payload to the network entity 105-c on the PUSCH. At 725, the network entity 105-b may process the msgA preamble and payload including an RRC connection request, SR, and / or buffer status. At 730, the network entity 105-b may transmit a msgB to the network entity 105-c on the PDCCH. At 735, the network entity 105-b may transmit a msgB to the network entity 105-c on the PDSCH. The msgB may include a timing advance, a TC-RNTI, and a content parsing message. At 740, the UE 115-d may transmit feedback information (e.g., HARQ ACK / NACK) to the network entity 105-c on the PUCCH.

[0137] In some examples, rate splitting may be used for initial access messages, such as the Figure 6 four-step RACH process described above and Figure 7RACH messages for the two-step RACH procedure. For example, network entity 105 may transmit the common part of rate-split transmission across combined SSB beams to multiple UEs 115, and network entity 105 may transmit the dedicated part of rate-split transmission to a dedicated UE. In some examples, rate-split techniques may be applied to layer 1 transmission. In some examples, both the common part and the dedicated part may be transmitted on the same beam (such as a single SSB beam). With different power control at network entity 105-c, UE 115-d may remove the common part and determine the dedicated part, assuming more power is used for the common part.

[0138] In some examples, network entity 105 may indicate in the MIB whether a rate-split scheme is used to transmit SIB1 PDSCH, msg2 or msg4 in the four-step RACH procedure, msgB in the two-step RACH procedure, or one or more other SIBS (OSIBs). In some examples, network entity 105 may indicate in the PDCCH of the SIB that a rate-split scheme is used to transmit the PDSCH of the SIB. In some examples, network entity 105 may indicate in the SIB PDCCH or SIB PDSCH whether a rate-split scheme is used to transmit msg2 or msg4 in the four-step RACH procedure, or msgB in the two-step RACH, or OSIB. In some examples, network entity 105 may indicate in the msg2 PDCCH of the four-step RACH whether a rate-split scheme is used to transmit the msg2 PDSCH. Network entity 105 may indicate in the msg2 PDCCH or msg2 PDSCH whether a rate-split scheme is used to transmit the msg4 OSIB in the four-step RACH or the msgB OSIB in the two-step RACH. In some examples, if network entity 105 is using a rate-split scheme to transmit a message, the DCI (e.g., using a new DCI format) may include multiple fields for MCS or redundancy version (RV) or the number of layers (or streams) or time-domain resource allocation (TDRA) and frequency-domain resource allocation (FDRA) (if these parameters are not shared between the dedicated part and the common part).

[0139] In some aspects, different messages may be rate-split together for different UEs. For example, msg2 for one UE may be rate-split with msg4 for another UE (e.g., the common part may include a combined CW that includes msg2 for one UE and msg4 for another UE). As another example, an initial access message for one UE (e.g., ms2 and msg4 or msgB) may be rate-split with a downlink data message for another UE (e.g., a PDSCH message).

[0140] In some examples, a rate splitting scheme may be used to send which initial access messages may be based on an indication in the MIB or SIB1. In such examples, some configurations may be fixed to the number of layers for each message type. In some examples, the MCS values and MCS table for the common layer and the number of layers for each message type may be specified, pre-configured, configured, loaded, or declared (e.g., in RRC signaling) per frequency band or per frequency band combination.

[0141] In some examples, network entity 105 may indicate in control signaling (e.g., MIB or SIB) or in one RACH message among RACH messages which subsequent RACH messages will be sent using a rate splitting scheme. The control signaling may indicate the number of layers and the MCS associated with each rate split message. UE 115 may accordingly decode the indicated rate split RACH messages. In some examples, the DCI of the rate split message may include an additional bit related to the use of rate splitting in the PDSCH. In some examples, the indication of rate splitting may be located in a previous message. For example, the MIB may indicate rate splitting for SIB1.

[0142] In some examples, if PDCCH is used to indicate whether rate splitting is being used for the PDSCH, the search space, format, radio network temporary identifier (RNTI), or size of the DCI is different from that of a conventional DCI, and UE 115 may search for both (e.g., similar to the conventional rate split DCI search in other connected mode messages). In some examples, the MCS table for the dedicated and common parts of each initial access message may be provided in the MIB, provided in SIB1, provided in the corresponding PDCCH, or based on some procedure for finding the PDCCH type or format (e.g., some RNTI or search space combination), or pre-configured and varied per frequency band or frequency range. In some examples, the MCS table for the dedicated and common parts of each initial access message may be shared among all initial access messages or a set of initial access messages in the initial access message, and may be provided in the specification per frequency band or frequency range, signaled in the MIB, or signaled in SIB1.

[0143] Figure 8Illustrates an example of a process flow 800 that supports priorities and feedback for a rate splitting scheme in accordance with one or more aspects of the present disclosure. The process flow 800 may include a UE 115-e and a network entity 105-d, which may be examples of the corresponding devices described herein. In the following description of the process flow 800, operations between the network entity 105-d and the UE 115-e may be sent in an order different from the example order shown, or operations performed by the network entity 105-d and the UE 115-e may be performed in a different order or at different times. Some operations may also be omitted from the process flow 800, and other operations may be added to the process flow 800.

[0144] At 805, the network entity 105-d may send control signaling that indicates a first communication resource for feedback associated with a common portion of a transmission (e.g., a rate split transmission) and a second communication resource for feedback associated with a dedicated portion of the transmission. At 810, the network entity 105-d may send the common portion and the dedicated portion. At step 815, the UE 115-e may send a feedback message for the common portion via one of the first communication resource or the second communication resource.

[0145] In some examples, the UE 115-e may send an indication of a first processing time of the UE 115-e associated with preparing feedback for the common portion of the transmission and a second processing time of the UE 115-e associated with preparing feedback for the dedicated portion of the transmission. The control signaling at 805 may be responsive to the indication of the first processing time and the second processing time.

[0146] In some examples, the UE 115-e may send a feedback message for the common portion in a first feedback resource and a feedback message for the dedicated portion in a second feedback resource.

[0147] In some examples, if the UE 115-e sends a negative acknowledgment feedback message for the common portion, the UE 115-e may cancel sending the feedback message for the dedicated portion.

[0148] In some examples, if the first feedback resource is unavailable (e.g., due to a scheduling conflict), the UE 115-e may send a feedback message for the common portion via the second feedback resource and may cancel sending the feedback message for the dedicated portion.

[0149] In some examples, the UE 115-e may determine that a first feedback resource is unavailable, and may multiplex a feedback message for a common part with a feedback message for a dedicated part, and send the feedback message and the second feedback message in the same transmission via a second feedback resource. In some examples, the UE 115-e may send the feedback message via a first subset of communication resources in a second communication resource, and may send the second feedback message via a second subset of communication resources in the second communication resource. In some examples, the UE 115-e may encode the feedback message and the second feedback in the same CW using a polar encoder or a single cyclic shift.

[0150] In some examples, the first feedback resource may include a first set of symbols in a time slot, and the second feedback resource may include a second set of symbols in the time slot.

[0151] In some examples, the UE 115-e may send the feedback message via the first feedback resource based on the feedback message having a higher priority than an uplink control message (e.g., another UCI) scheduled for transmission via a first resource, and may cancel the transmission of the uplink control message. In some examples, the UE 115-e may determine that the uplink control message is scheduled for transmission via a second communication resource, the UE 115-e may send the uplink control message via the second communication resource based on the uplink control message having a higher priority level than the feedback message for the dedicated part, and the UE 115-e may cancel the transmission of the feedback message for the dedicated part.

[0152] In some examples, the UE 115-e may receive control signaling that indicates a timing offset between a communication resource for feedback for a common part and a communication resource for a dedicated part, and the control signaling includes an indication of a start time (e.g., a first RB) of a first communication resource. Accordingly, the UE 115-e may determine the second communication resource based on the timing offset and the start time of the first communication resource.

[0153] In some examples, the UE 115-e may receive DCI for scheduling a transmission.

[0154] In some examples, the UE 115-e may receive second control signaling indicating that a RACH message is rate-split, and the transmission includes the RACH message.

Although the communication manager 1220 is illustrated as a separate component, in some examples, one or more of the functions described with reference to the communication manager 1220 may be supported or performed by the processor 1240, the memory 1230, the code 1235, or any combination thereof. For example, the code 1235 may include instructions that, when executed by the processor 1240, cause the device 1205 to perform various aspects of prioritization and feedback for a rate splitting scheme as described herein, or the processor 1240 and the memory 1230 may otherwise be configured to perform or support such operations.
