Background Art

[0003] The following relates to wireless communication associated with frequency hopping across subbands within a bandwidth part (BWP). Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. 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 supporting wireless communication for communication devices, which may be referred to as user equipment (UE). Summary of the Invention

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting frequency hopping across subbands within a bandwidth part (BWP). For example, the described techniques enable a device to switch or hop between subbands within a BWP configured for the device according to a specified frequency hopping pattern, which can improve frequency diversity, throughput, and communication reliability. A first network node (e.g., a network entity, a base station, or some other device) may send a first control message to a second network node (e.g., a user equipment (UE) or some other device), the first control message indicating a set of one or more frequency hopping patterns for switching between two or more subbands within a BWP configured for the second network node. In some aspects, the first control message may include a radio resource control (RRC) message that configures a set of one or more grants for scheduling communications performed by the second network node, and the first control message may indicate a corresponding set of frequency hopping patterns for each grant. In some aspects, the first control message may indicate a default frequency hopping pattern, and the first network node and the second network node may communicate via at least two subbands within the BWP according to the default frequency hopping pattern.

[0005] Additionally or alternatively, the first network node may send a second control message that indicates a specified frequency hopping pattern from the set of one or more frequency hopping patterns indicated by the first control message. The first network node and the second network node may communicate via at least two subbands within the BWP according to the specified frequency hopping pattern indicated by the second control message. Thereby, the first network node may indicate a frequency hopping pattern for communicating via two or more subbands within the BWP, which can enable the second network node to support a reduced bandwidth while maintaining frequency diversity by switching between subbands according to the frequency hopping pattern.

[0051] Some wireless communication systems may support device communication within a system bandwidth part (BWP) (e.g., a 20 megahertz (MHz) BWP or some other BWP size). However, some devices in a wireless communication system, such as reduced-capability devices or enhanced reduced-capability devices (e.g., eRedCap user equipment (UE)), may be configured to have a reduced baseband bandwidth within the system BWP. For example, the system BWP may be applicable to the device, which means the device may be able to communicate using the entire BWP but not simultaneously. The device may support communication within a single subband of the system BWP at any given moment. In one aspect, the system BWP may be 20 MHz, and the baseband bandwidth of the device may be up to 5 MHz, or some other relative size. Such devices may not support frequency hopping across the BWP, which may reduce the frequency diversity of communication.

[0052] The techniques, systems, and devices described herein enable a first network node to configure a frequency hopping pattern that indicates a pattern for a second network node to switch between subbands within a system BWP for communication. The first network node and the second network node may represent examples of network entities, UEs, or some other devices that communicate via a wireless communication link. By switching between subbands within the BWP according to the frequency hopping pattern, the second network node may communicate within a single subband (e.g., a reduced bandwidth) at a time while improving or maintaining the frequency diversity, throughput, and reliability of communication. The frequency hopping pattern may indicate the order of subband hopping to be used during frequency hopping, the time duration for communicating via each subband, the periodicity associated with the switch between subbands, or any combination thereof.

[0053] The first network node may send one or more control messages to configure or activate the frequency hopping pattern. For example, the first network node may send a first control message to configure a set of one or more frequency hopping patterns available for the second network node. The first control message may configure a set of grants for scheduling communication with the second network node, such as configured grants, semi-persistent scheduling (SPS) grants, downlink control information (DCI) grants, or any combination thereof. The first control message may indicate the corresponding set of one or more frequency hopping patterns associated with each grant configuration. In some aspects, the first control message may indicate a default frequency hopping pattern, and the second network node may communicate according to the default frequency hopping pattern. Additionally or alternatively, the first network node may send a second control message that indicates a specified frequency hopping pattern among the one or more frequency hopping patterns indicated by the first control message.

[0054] The described techniques may be applied to different types of uplink and downlink communications, including communications scheduled by configured grants (e.g., type 1 or type 2), SPS scheduling, and active DCI. In some aspects, the first control message may be a radio resource control (RRC) message that configures a configured grant or SPS and a set of multiple hopping patterns, and the second control message may be a media access control - control element (MAC-CE) or an active DCI. Thereby, the first network node may indicate a hopping pattern for communicating via two or more subbands within a BWP, which may enable the second network node to support reduced bandwidth while maintaining frequency diversity by switching between subbands according to the hopping pattern.

[0055] Aspects of the present disclosure are first described in the context of a wireless communication system. Additional aspects are described with reference to hopping patterns and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts related to hopping across subbands within a BWP.

[0056] Figure 1 An example of a wireless communication system 100 that supports hopping across subbands within a BWP 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 aspects, 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).

[0057] The network entities 105 may be dispersed over a geographical area to form the wireless communication system 100 and may include devices in different forms or having different capabilities. In various aspects, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, etc. In some aspects, 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).

[0058] 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 UE 115 described herein may be capable of supporting communication with various types of devices, such as other UEs 115 or network entities 105, as Figure 1 shown.

[0059] As described herein, a node (which may be referred to as a node, network node, network entity, or wireless node) may include the following, may be the following, or may be included in the following (e.g., as a component of the following): a base station (e.g., any base station described herein), a UE (e.g., any UE described herein), a network controller, a device, an apparatus, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, a network node may be a UE. As another example, a network node may be a base station or a network entity. As yet another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a UE. In another aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In other aspects of this example, the first network node, the second network node, and the third network node may be different from these examples. Similarly, references to UEs, base stations, devices, apparatuses, computing systems, etc. may include the disclosure of UEs, base stations, devices, apparatuses, computing systems, etc. as network nodes. For example, the disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with this disclosure, once a particular example is extended in accordance with this disclosure (e.g., the disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), the broader example of the narrower example may be interpreted in reverse, but in a broad open-ended manner. In the above example where the disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first device, a first apparatus, a first computing system, a first set of one or more components, a first processing entity, etc. configured to receive information; and the second network node may refer to a second UE, a second base station, a second device, a second apparatus, a second computing system, a second set of one or more components, a second processing entity, etc.

[0060] As described herein, different terms may be used in various aspects to describe the conveyance of information (e.g., any information, signal, etc.). The disclosure of one communication term includes the disclosure of other communication terms. For example, a first network node may be described as being configured to send information to a second network node. In this example and consistent with the present disclosure, the disclosure that the first network node is configured to send information to the second network node includes the disclosure that the first network node is configured to provide, transmit, output, convey, or send information to the second network node. Similarly, in this example and consistent with the present disclosure, the disclosure that the first network node is configured to send information to the second network node includes the disclosure that the second network node is configured to receive, obtain, or decode the information provided, transmitted, output, conveyed, or sent by the first network node.

[0061] In some aspects, the network entity 105 may communicate with the core network 130, or with each other, or both. For example, the network entity 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to the S1, N2, N3, or other interface protocols). In some aspects, the network entities 105 may communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to the X2, Xn, or other interface protocols). In some aspects, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), and other aspects or various combinations thereof. The UE 115 may communicate with the core network 130 via the communication link 155.

[0062] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB, or giga NodeB (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home NodeB, home eNodeB, or other suitable terms). In some aspects, the network entity 105 (e.g., base station 140) may be implemented in an integrated (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).

[0063] In some aspects, the network entity 105 may be implemented in a disaggregated architecture (e.g., disaggregated base station architecture, disaggregated RAN architecture) that may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 105 (such as an integrated access backhaul (IAB) network, open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or virtualized RAN (vRAN) (e.g., cloud RAN (C-RAN))). For example, the 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., near-real-time RIC (near RT RIC), 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, intelligent 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 a 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 aspects, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0064] 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 adopted 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 aspects, 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 adopted 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 aspects, 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 corresponding network entities 105 communicating via such communication links.

[0065] In a wireless communication system (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 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 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). An IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by the DU 165 of a coupled IAB donor. The IAB-MT may include a separate antenna set for relaying communications 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 aspects, 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 split 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.

[0066] 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), in which case 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 (e.g., the F1 AP protocol) that defines signaling messages. 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 donors) via an Xn-C interface (which may be an example of a part of the backhaul link).

[0067] The IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for the UE 115, wireless self-backhaul capability). The DU 165 may act as a distributed scheduling node towards the child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards the 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 the transmission of the 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 the child IAB node 104 to receive signaling from the parent IAB node 104, and the DU interface (e.g., the 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.

[0068] For example, the IAB node 104 may be referred to as a parent node supporting communication for a sub-IAB node or as a sub-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., a fronthaul communication link 120), and may act as the 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 the 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.

[0069] 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 frequency hopping across subbands within a BWP 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).

[0070] The 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 term, where the "device" may also be referred to as a unit, a station, a terminal, or a client, etc. The 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 aspects, the UE 115 may include or 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.

[0071] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc., asFigure 1 as shown

[0072] UE 115 and network entity 105 may 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" may refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of an RF spectrum band (e.g., 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 may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, 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 network entity 105 and other devices may refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms "transmit", "receive", or "communicate" when referring to network entity 105 may refer to any part of 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).

[0073] In some aspects, 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 UE 115. A carrier may operate in a stand-alone mode, in which case, initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-stand-alone mode, in which case, a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0074] The communication link 125 shown in the wireless communication system 100 may include a downlink transmission (e.g., forward link transmission) from the network entity 105 to the UE 115, an uplink transmission (e.g., reverse link transmission) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. 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).

[0075] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some aspects, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the 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). Devices of the wireless communication system 100 (e.g., the network entity 105, the 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 a set of carrier bandwidths. In some aspects, 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 aspects, each served UE 115 may be configured to operate using a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0076] The signal waveform transmitted via a 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 an MCM technique, a resource element may 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 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 decoding rate of the modulation scheme, or both), such that a relatively large number of resource elements (e.g., during 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 space resources (e.g., spatial layer or beam), and the use of multiple space resources may increase the data rate or data integrity for communication with the UE 115.

[0077] One or more parameter sets may be supported for a carrier, and the parameter set may include the subcarrier spacing ( )(and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some aspects, UE 115 can be configured with multiple BWPs. In some aspects, a single BWP of a carrier can be active at a given time, and the communication of UE 115 can be restricted to one or more active BWPs.)

[0078] A time interval for a network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, which can refer to, for example, a sampling period seconds, where can represent the supported subcarrier spacing, and can represent the supported discrete Fourier transform (DFT) size. The time intervals of 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).

[0079] 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 aspects, 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., number of) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.)

[0080] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain), and can be referred to as a transmission time interval (TTI). In some aspects, 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)).

[0081] Physical channels can be reused according to various techniques for communication using a carrier. 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 to signal 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.

[0082] 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 identifier) for differentiating adjacent cells. In some aspects, a cell can also refer to a coverage area 110 or a portion 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 with the coverage areas 110, etc.

[0083] Macro cells generally cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access for UEs 115 that have a service subscription with the network provider that supports the macro cell. Small cells can be associated with a lower power network entity 105 (e.g., a lower power base station 140) (as compared to a macro cell), and small cells can operate using the same or a different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell 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.

[0084] In some aspects, 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)).

[0085] In some aspects, the network entity 105 (e.g., base station 140, RU 170) can be mobile and thus provide communication coverage for a mobile coverage area 110. In some aspects, although different coverage areas 110 associated with different technologies can overlap, different coverage areas 110 can be supported by the same network entity 105. In some other aspects, overlapping coverage areas 110 associated with different technologies may 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.

[0086] 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 aspects, transmissions from different network entities 105 can be misaligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

[0087] Some UEs 115 (such as MTC or IoT devices) can be low-cost or low-complexity devices and can allow 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 aspects, M2M communication or MTC can include communication from devices with integrated sensors or meters to measure or capture 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 enable 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, wilderness survival monitoring, weather and geographical event monitoring, formation management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0088] Some UEs 115 can be configured to operate in power-saving modes such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not concurrent transmission and reception). In some aspects, half-duplex communication can be performed at a reduced peak rate. Other energy-saving techniques for UEs 115 include: entering a power-saving deep sleep mode when not participating in active communication, operating with limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 can be configured to operate using a narrowband protocol type 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 the carrier, or outside the carrier.

[0089] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UEs 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.

[0090] In some aspects, UE 115 may be configured to support communicating 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 aspects, one or more UEs 115 performing D2D communication in a group may be within the coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), and such network entity may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some aspects, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some aspects, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some aspects, the network entity 105 may facilitate scheduling resources for D2D communication. In some other aspects, D2D communication may be performed between UEs 115 without involving the network entity 105.

[0091] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some aspects, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some aspects, vehicles in a V2X system may 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 communicate with both.

[0092] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which can 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 external networks (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 can 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 can be passed through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to the IP services 150 of one or more network operators. The IP services 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.

[0093] The wireless communication system 100 can operate using one or more frequency bands (which can be in the range of 300 MHz to 300 gigahertz (GHz)). Generally, the region from 300 MHz to 3 GHz is referred to 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 can be blocked or redirected by buildings and environmental features (which can be referred to as clutter), but these waves can be sufficient to penetrate structures so that macrocells can serve 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 can 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) band, which may be in the range of 3 GHz to 30 GHz (also known as the centimeter band), or using the extremely high frequency (EHF) band of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some aspects, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and network entities 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices may be smaller and more closely spaced compared to UHF antennas. In some aspects, such techniques may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range 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), LTE-unlicensed (LTE-U) radio access technology, or NR technology. When operating using an unlicensed RF spectrum band, devices such as network entities 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some aspects, operations using an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in combination with operations using a licensed band. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, etc.

[0096] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which 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 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 at an antenna tower. In some aspects, 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 in multiple rows and columns that the network entity 105 may use for beamforming to support communication 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 panel may support RF beamforming for signals transmitted via the antenna ports.

[0097] The network entity 105 or UE 115 may use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may be transmitted, 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), for which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

[0098] 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., network entity 105, 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 signals communicated via the antenna elements of an antenna array such that some signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals communicated 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] Network entity 105 or UE 115 can use beam scanning techniques as part of beamforming operations. For example, network entity 105 (e.g., base station 140, RU 170) can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted by network entity 105 multiple times in different directions. For example, network entity 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmission along different beam directions can be used to identify (e.g., by the transmitting device such as network entity 105, or by the receiving device such as UE115) the beam direction for later transmission or reception by network entity 105.

[0100] Some signals (such as data signals associated with a particular receiving device) can 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 the receiving device such as receiving network entity 105 or receiving UE 115). In some aspects, the beam direction associated with transmission along a single beam direction can be determined based on signals transmitted along one or more beam directions. For example, UE 115 can receive one or more of the signals transmitted by network entity 105 in different directions and can 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 aspects, transmissions performed by a device (e.g., by network entity 105 or UE 115) can be carried out using multiple beam directions, and the device can 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 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to a configured set of beams across the system bandwidth or one or more subbands. Network entity 105 can transmit reference signals (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)), which may or may not be precoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection 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 can use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions used by UE 115 for subsequent transmissions or receptions), or for transmitting signals in a single direction (e.g., for sending data to a receiving device).

[0102] A receiving device (e.g., UE 115) can 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 receiving device (e.g., network entity 105). For example, the receiving device can perform receiving according to multiple receiving directions by: receiving via different antenna subarrays, processing the received signals according to different antenna subarrays, receiving according to different sets of receiving beamforming weights (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of an antenna array, any of which can refer to "listening" according to different receiving configurations or receiving directions. In some aspects, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receiving configuration can 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 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reassembly for conveyance via logical channels. The MAC layer can perform priority handling and multiplexing from logical channels into transport channels. The MAC layer can also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer can provide the 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 can map the transport channels to physical channels.

[0104] The UE 115 and the network entity 105 can support the retransmission of data to increase the likelihood that the data is successfully received. 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 can 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 the throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some aspects, the device can support same-slot HARQ feedback, in which case the device can provide HARQ feedback for data received in a previous symbol in a particular slot during that slot. In some other aspects, the device can provide HARQ feedback in a subsequent slot or according to some other time interval.

[0105] The techniques, systems, and devices described herein enable one or more devices in the wireless communication system 100 to switch or hop between subbands within a BWP configured for the device according to a specified hopping pattern, which can improve the frequency diversity, throughput, and reliability of the communication. A first network node (e.g., network entity 105, base station 140, or some other device) can send a first control message to a second network node (e.g., UE 115 or some other device), the first control message indicating a set of one or more hopping patterns for switching between two or more subbands within the BWP configured for the second network node. In some aspects, the first control message can include an RRC message that configures a set of one or more grants for scheduling the communication by the second network node, and the first control message can indicate a corresponding set of hopping patterns for each grant. In some aspects, the first control message can indicate a default hopping pattern, and the first network node and the second network node can communicate via at least two subbands within the BWP according to the default hopping pattern.

[0106] Additionally or alternatively, the first network node may send a second control message that indicates a specified hopping pattern in the set of one or more hopping patterns indicated via the first control message. The first network node and the second network node may communicate via at least two subbands within the BWP according to the specified hopping pattern indicated via the second control message. Thereby, the first network node may indicate a hopping pattern for communication via two or more subbands within the BWP, which may enable the second network node to support reduced bandwidth while maintaining frequency diversity by switching between subbands according to the hopping pattern.

[0107] Figure 2 An example of a wireless communication system 200 that supports hopping across subbands within a BWP in accordance with one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may implement aspects of the wireless communication system 100 as described with reference to Figure 1 or may be implemented by aspects of the wireless communication system. For example, the wireless communication system 200 may include a network node 205 and a network node 215, which may represent examples of the network entity 105 and UE 115 or some other device as described with reference to Figure 1 The network node 205 may be within a geographic coverage area 110-a and communicate with the network node 215 via a communication link 210 (e.g., a Uu link). In this example, the network node 205 may indicate a set of hopping patterns 230 to the network node 215, and the network node 215 may use at least one of these hopping patterns 230 to switch between subbands 240 within the system BWP 235.

[0108] Devices in the wireless communication system 200 may support a range of different device capabilities. In some aspects, a device may support reduced capabilities to reduce power consumption and complexity. A device operating with reduced capabilities may be referred to as a RedCap (e.g., NR lightweight) device or an enhanced RedCap (eRedCap) (e.g., NR ultra-lightweight) device. Examples of such devices may include wearable devices, wireless sensors, health monitors, low-quality smartphones, parking sensors, utility meters, asset trackers, or other devices (e.g., devices supporting IoT, massive IoT, or low-power wide-area (LPWA) systems, etc.).

[0109] Various communication parameters may vary depending on different devices operating at different capability levels. For example, the number of duplex mode types supported by a device, the number of MIMO layers, the peak data rate, the number of antenna elements, the channel decoding type, the maximum modulation order, the maximum coupling loss (MCL), other parameters, or any combination thereof may change as the device capabilities change. Additionally or alternatively, the bandwidth supported by a device may decrease as the device capabilities decrease.

[0110] To support reduced complexity, an eRedCap UE may, for example, support communicating via a smaller bandwidth than that supported by another UE that is not an eRedCap UE. The other UE may monitor communications within system BWP 235, and the eRedCap UE may monitor a single subband 240 within system BWP 235 at a time. The subband 240 may span a frequency range that is less than the frequency range of system BWP 235 (e.g., a 5 MHz subband 240 within a 20 MHz system BWP 235 in FR1, or some other frequency range size). Reduced bandwidth operation may apply with or without a synchronization signal block (SSB) and with or without radio frequency (RF) retuning. In some aspects, the eRedCap UE may additionally or alternatively support a relaxed processing timeline, a reduced peak data rate (e.g., in FR1), a reduced or restricted bandwidth for a downlink or uplink shared channel, or any combination thereof, for an uplink or downlink channel or channel state information (CSI).

[0111] In some aspects, BWP 235 may be configured for uplink or downlink communication (e.g., a 20 MHz or 100 MHz BWP in FR1, or some other frequency range) by a device in a wireless communication system 200. Some devices may communicate within a single BWP 235 at a time and may switch between different BWPs 235 over time to achieve frequency diversity. The frequency domain resource allocation (FDRA) of system BWP 235 may start from a first physical resource block (PRB) within system BWP 235 (e.g., the first frequency resource in the frequency domain) and may span a certain number of PRBs in the frequency domain. In an example of wireless communication system 200, compared to some other network nodes 215 ( Figure 2 not shown), network node 215 may support a reduced (e.g., restricted or limited) bandwidth. That is, system BWP 235 may be applicable to network node 215, but network node 215 may support a baseband bandwidth that is a subset of system BWP 235 (e.g., one subband 240) at a time (e.g., to reduce the peak data rate or buffer size of network node 215).

[0112] The techniques, systems, and devices described herein enable network node 215 to support communicating via a single subband 240 at a time and switching between different subbands 240 within system BWP 235 over time to achieve frequency diversity. For example, BWP235 may be divided into one or more subbands 240 (e.g., Figure 2sub - bands 0, sub - band 1, sub - band 2, and sub - band 3). Each sub - band 240 may span a frequency range that is approximately the same as that of each other sub - band 240. The frequency range of the sub - bands 240 may be less than or equal to the frequency range supported by the network node 215 at one time (e.g., the number N of resource blocks RB )(e.g., 5 MHz or some other baseband bandwidth). The network node 215 may switch between sub - bands 240 over time for communication, which may enable the network node 215 to improve frequency diversity, thereby increasing the throughput and reliability of communication.

[0113] The starting point of the sub - band 240 may be determined relative to the first PRB of the BWP 235 (e.g., PRB0) and may be based on the sub - carrier spacing (SCS) configured for the BWP 235. The offset of each sub - band 240 may be determined based on the maximum bandwidth N supported by the network node 215 RB (e.g., the offsets 0 to 3 in Figure 2 ). For example, the offset k may be located at a distance of k * N resource blocks from the first resource block in the BWP 235, where N RB may represent the number of resource blocks included in the baseband bandwidth of the network node 215. If the number of resource blocks included in the sub - band 240 is equal to or less than N RB , then each sub - band 240 may be valid. For communication within a given sub - band 240, the FDRA for downlink reception or uplink transmission performed by the network node 215 may start in the first resource block of the valid sub - band 240. For example, RB the FDRA for communication 225 via sub - band 1 illustrated in Figure 2 may start in the first resource block at offset 1 in the frequency domain.

[0114] The network node 205 may schedule the communication 225 with the network node 215. The communication 225 may include an uplink transmission by the network node 215, a downlink transmission by the network node 205, or both. The type of scheduling grant used by the network node 205 may include a configured grant (e.g., configured grant type 1 or configured grant type 2), semi-persistent scheduling (SPS), dynamic activation DCI for a shared channel (e.g., multiple physical downlink shared channels (PDSCH) or physical uplink shared channels (PUSCH)), or any combination thereof. The network node 205 may send a first control message 220 for the configured grant. For example, for type 1 and type 2 configured grants, the control message 220 may be sent as an RRC configuration that configures the uplink or downlink grant for each serving cell and each BWP 235. For type 1 configured grants, the RRC configuration may define the grant configuration. For type 2 configured grants, the network node 205 may send a second control message 220 (such as DCI), which may activate a subset of one or more of these grant configurations.

[0115] As described herein, the first control message 220 sent by the network node 205 may additionally or alternatively indicate a set of one or more hopping patterns 230 associated with each of these grant configurations. For example, the first control message 220 may indicate a first set of hopping patterns 230 associated with a first grant configuration, a second set of hopping patterns associated with a second grant configuration, and so on. Each hopping pattern 230 (e.g., Figure 2 the patterns 0-3 illustrated in) may define or indicate a corresponding set of hopping parameters for the network node to follow during communication. For example, each hopping pattern 230 may indicate the order of subbands 240, the time period or periodicity for switching between subbands 240, other hopping parameters, or any combination thereof. Example hopping patterns are defined and described in further detail elsewhere herein (including with reference to Figure 3A and Figure 3B ).

[0116] In some aspects (e.g., for type 1 configured grants or SPS communication), the first control message 220 sent by the network node 205 may activate or configure one of the grants for use by the network node 215. In such cases, the first control message 220 may indicate the default hopping pattern 230 in the set of hopping patterns 230 associated with the activated grant. For example, if the activated grant is associated with patterns 0-3, the first control message 220 may indicate that the default pattern is pattern 0. The network node 205 may receive the first control message 220 and send or receive the communication 225 according to the default hopping pattern 230 for at least a period of time.

[0117] The network node 215 may communicate according to the default hopping pattern 230 until a subsequent grant is activated. Additionally or alternatively, the network node 205 may send a second control message 220 (e.g., MAC-CE) that indicates or activates a specified hopping pattern 230 different from the default hopping pattern. For example, if the default mode is mode 0, the second control message 220 may activate mode 2. In such cases, the network node 215 may switch from communicating according to the default hopping pattern 230 to communicating according to the specified hopping pattern 230 in response to the second control message 220.

[0118] In some other aspects (e.g., type 2 configured grants or SPS communications, or communications where DCI activates multiple shared channels), the first control message may configure the grant configuration, and the network node 205 may send a second control message 220 to activate one of the grant configurations in the grant configuration. In such cases, the first control message 220 may indicate the respective sets of one or more hopping patterns 230 associated with each grant, and the second control message 220 may activate the grant configuration and indicate the specified hopping pattern in the set of one or more hopping patterns 230 associated with the grant configuration. The second control message 220 may include DCI (e.g., activation DCI) or be sent as DCI. In some aspects, the network node 205 may send a third control message 220 after the first control message 220 and before the second control message 220. For example, the third control message 220 may include MAC-CE or be sent as MAC-CE. The third control message 220 may select or indicate a subset of the hopping patterns 230 from the set of hopping patterns 230 indicated via the first control message 220, and the second control message 220 may then indicate one of the hopping patterns 230 from the subset indicated via the MAC-CE.

[0119] Thus, the devices described herein may support reduced bandwidth (e.g., sub-bands 240 within the system BWP 235), while maintaining relatively high frequency diversity, throughput, and communication reliability by switching between the sub-bands 240 within the BWP 235 over time according to a specified or defined hopping pattern. By sending one or more control messages 220 to indicate the specified hopping pattern, the network node 205 may improve coordination between devices while supporting the hopping techniques described herein. The network node 215 may send and / or receive communications 225 over time based on the hopping pattern 230, according to one or more grants (e.g., SPS grants, configured grants, or activation DCI scheduling the transmission of one or more shared channels) across different sub-bands 240.

[0120] Figure 3A and Figure 3BIllustrates an example of a frequency hopping pattern 300 that supports frequency hopping across subbands within a BWP. In some aspects, frequency hopping patterns 300-a and 300-b may implement aspects of wireless communication systems 100 or 200. For example, a first network node and a second network node (e.g., a UE, a network entity, or some other node) may switch between subbands 305 within a BWP according to frequency hopping pattern 300. The network nodes may perform communication 325 via each subband 305 over time based on the pattern. In this example, the horizontal or X-axis may represent time, and the vertical or Y-axis may represent frequency.

[0121] In some aspects, communication 325 may be scheduled or allocated based on one or more grants (such as an SPS grant, a configured grant, a dynamically activated DCI, or any combination thereof), as referenced Figure 2 as described. Figure 3A and Figure 3B The communication boxes 325 illustrated in Figure 3A and Figure 3B may each represent a corresponding transmission opportunity 315 (e.g., an SPS opportunity or a configured grant opportunity, which may be referred to as an uplink or downlink shared channel opportunity). Although illustrated as separate boxes in

[0122] and Figure 2 it should be understood that in some aspects, the network nodes may perform communication 325 (e.g., uplink, downlink, or both) via continuous or discontinuous time and frequency resources.

[0122] In this example, although not illustrated for clarity, subbands 305-a, 305-b, 305-c, and 305-d may be included in the BWP configured for communication by the second network node. For example, subbands 305 (e.g., subbands 305-a to 305-d) may represent an example of subbands 240 within BWP 235, as referenced Figure 2 as described. Subbands 305 may represent a frequency band that spans a certain frequency range based on the bandwidth supported by the second network node, as referenced Figure 2 and described in further detail.

[0123] To achieve frequency diversity while supporting a reduced bandwidth (e.g., a single subband 305), as described herein, the second network node may hop or switch between subbands 305 within a BWP over time. The techniques, systems, and devices described herein enable a first network node (e.g., a network entity) to configure a set of one or more frequency hopping patterns 300 for a second network node (e.g., a UE). The first network node may indicate a specified frequency hopping pattern from the set for the first network node to use for communication. As referenced Figure 2 and described in further detail, the first network node may indicate the specified frequency hopping pattern via one or more control messages.

[0124] Each hopping pattern may correspond to a pattern in which a first network node and a second network node switch between subbands 305 over time, and may be defined by or associated with a corresponding set of hopping parameters. The hopping parameters may include, for example, the time duration associated with each subband 305, the periodicity associated with each subband 305, the order of the subbands 305, other parameters, or any combination thereof.

[0125] Figure 3A An example hopping pattern 300-a that supports hopping across subbands within a BWP in accordance with one or more aspects of the present disclosure is illustrated. Hopping pattern 300-a illustrates a pattern in which a network node switches between at least subbands 305-d, 305-b, and 305-c over time. The subband hopping order associated with the hopping pattern may correspond to: subband 0, subband 2, subband 1. In some aspects, the pattern may continue in time to include a repetition of subbands or another subband (such as subband 3), or the pattern may repeat over time for a certain number of cycles or repetitions.

[0126] In some aspects, each hopping pattern 300 (including hopping pattern 300-a) configured by a first network node may be associated with one or more defined time durations (e.g., the time unit or number of transmission opportunities 315) during which the frequency is fixed before a new subband 305 is selected. In Figure 3A the example, in this aspect, the time duration of hopping pattern 300-a may be represented by time period 310-a and time period 310-b, which may be associated with the same duration. According to the subband hopping order defined for hopping pattern 300-a, hopping pattern 300-a may be associated with a time period 310 of approximately three transmission opportunities 315 before switching between subbands 305. Additionally or alternatively, time periods 310-a and 310-b may be defined in time units (e.g., milliseconds or some other unit).

[0127] In Figure 3A the example, if hopping pattern 300-a is associated with a defined time period 310 of three transmission opportunities 315, the network node may perform communication 325 (e.g., uplink or downlink transmission or reception) on subband 305-d during three transmission opportunities 315 before switching to subband 305-b. After switching to subband 305-b, the network node may perform communication 325 on subband 305-b during three transmission opportunities 315 according to the order indicated by hopping pattern 300-a before switching to subband 305-c, and so on.

[0128] Figure 3BIllustrates a second example hopping pattern 300-b that supports sub-band hopping within a BWP according to one or more aspects of the present disclosure. Hopping pattern 300-b illustrates a pattern in which a network node switches between at least sub-bands 305-d and 305-a over time. The sub-band hopping order associated with hopping pattern 300-b may correspond to: sub-band 0, sub-band 3. In some aspects, the pattern may continue in time to include a repetition of sub-band 305 or include another sub-band 305 (such as sub-bands 1 and 2), or the pattern may repeat over time for a certain number of cycles or repetitions.

[0129] In some aspects, hopping pattern 300 may define or be associated with different periodicities of grants across each sub-band 305. For example, as Figure 3B illustrated, a first time period 310-c associated with sub-band 305-d may be different from a second time period 310-d associated with sub-band 305-a, where time periods 310-c and 310-d may represent the periodicities associated with sub-bands 305-d and 305-a, respectively. Before switching to the next sub-band 305 in the order defined by hopping pattern 300, the network node may perform communication 325 via each sub-band 305 according to the corresponding periodicity. In some aspects, the periodicity of each sub-band 305 may be defined based on one or more communication parameters associated with the sub-band 305 (such as the frequency band occupancy of other network nodes).

[0130] In Figure 3B the example, if hopping pattern 300-b indicates a first periodicity associated with time period 310-c of sub-band 310-d and a second periodicity associated with time period 310-d of sub-band 305-a, the network node may communicate within time period 310-c (e.g., approximately two transmission opportunities 315) via sub-band 305-d before switching to sub-band 305-a to perform communication 325 within time period 305-d (e.g., approximately four transmission opportunities 315). In some aspects, these periodicities may correspond to the periodicity of grants of transmission opportunities 315 on sub-band 305.

[0131] In some aspects, a first network node may indicate or define multiple grant configurations, each grant configuration being associated with a different frequency domain resource allocation and a corresponding time period during which the configuration is valid. For example, the first network node may send a control message (e.g., an RRC configuration) indicating a set of different grant configurations. The control message may indicate the frequency domain resource allocation for each grant (e.g., the index of sub-band 305 within sub-bands 305 in a BWP). The control message may additionally or alternatively indicate the time period 310 associated with each grant. Thus, the second network node may switch between grant configurations according to the time period 310 (e.g., a timer).

[0132] The frequency hopping pattern 300-b can be based on a switch between grant configurations. For example, the transmission opportunity 315 on the sub-band 305-d within the time period 310-c can be associated with a first grant configuration. Once the time period 310-c expires, the network node can switch to a second grant configuration associated with the transmission opportunity 315 on the sub-band 305-a. In some other aspects, the first network node can send an active DCI 320, which activates one of the configured grants at a time, and the switch can be based on the active DCI 320 rather than a timer. For example, the first active DCI 320 can activate the first grant configuration on the sub-band 305-d, and a second active DCI 320 ( Figure 3B not shown in the figure) can be sent to activate the second grant configuration on the sub-band 305-a, and so on.

[0133] The first network node can send one or more control messages to indicate the default or specified frequency hopping pattern 300 for use by the second network node, as described in reference to Figure 2 . In some aspects, if the first network node sends a second control message indicating a specified frequency hopping pattern 300, the second network node can determine the specified frequency hopping pattern based on the sub-band 305 via which it receives the second control message. In such cases, the first control message can indicate the mapping between each frequency hopping pattern 300 in the set of one or more frequency hopping patterns 300 indicated by the first control message and the corresponding sub-band 305 among two or more sub-bands 305 within the BWP. In the Figure 3B example, the first control message can map the frequency hopping pattern 300-b to the sub-band 305-b (e.g., sub-band 2). The active DCI 320 can be received via the sub-band 305-b. The second network node can determine that the active DCI 320 indicates (e.g., selects, indicates, or activates) the frequency hopping pattern 300-b based on the active DCI 320 being received via the sub-band 305-b and the mapping. Additionally or alternatively, the active DCI 320 can include one or more bits or fields configured to indicate an index or pointer pointing to the specified frequency hopping pattern.

[0134] In some aspects, the first network node can indicate that frequency hopping is valid and the set of sub-bands 305 on which it will be applied. The first network node can send this indication via RRC configuration or some other type of control message. The indicated set of sub-bands can be applied to SPS, configured grant scheduling, or multiple shared channel scheduling scenarios. In Figure 3BIn the example of [[ID=]], the first network node may indicate sub - bands 305 - a to 305 - d in the BWP. Sub - bands 305 - a and 305 - d are valid for frequency hopping, while the other sub - bands 305 - b and 305 - c are invalid for frequency hopping (e.g., only sub - bands {0, 3} from the set of sub - bands {0, 1, 2, 3} are used). The sub - bands 305 included in the frequency - hopping pattern 300 may be based on this indication.

[0135] Thus, the frequency - hopping pattern 300 described herein may indicate the order of sub - bands 305 and the corresponding frequency resource allocation, one or more time periods 310 for switching between sub - bands 305 (e.g., the number of transmission opportunities 315, time duration, periodicity, etc.), other parameters, or any combination thereof. The network node may perform communication 325 on at least two sub - bands 305 within the BWP via one or more transmission opportunities 315 by switching between sub - bands 305 according to the frequency - hopping parameters.

[0136] Figure 4 An example of a process flow 400 that supports frequency hopping across sub - bands within a BWP in accordance with one or more aspects of the present disclosure is illustrated. The process flow 400 may implement or be implemented by aspects of the wireless communication systems 100 and 200 or the frequency - hopping pattern 300 as described with reference to Figure 1 FIGS. 1 to 3. For example, the process flow 400 illustrates communication between a network node 405 and a network node 415, which may represent aspects of corresponding devices (e.g., UEs, network entities, or some other devices) as described with reference to Figure 1 FIGS. 1 to 3. In some aspects, the network node 405 may send one or more control messages to the network node 415 to indicate or configure a specified frequency - hopping pattern. The network node 415 may switch between frequency sub - bands within the BWP based on the specified frequency - hopping pattern.

[0137] In the following description of the process flow 400, the operations between the network node 405 and the network node 415 may be performed in a different order or at different times. Some operations may also be excluded from the process flow 400, or other operations may be added. Although the network node 405 and the network node 415 are shown as performing the operations of the process flow 400, some aspects of some operations may also be performed by one or more other wireless devices.

[0138] At 420, the network node 405 may send a first control message to the network node 415. The first control message may indicate a set of one or more frequency - hopping patterns for switching between two or more sub - bands within the BWP (e.g., the system BWP) configured for the network node 415. In some aspects, the first control message may be an RRC configuration that configures one or more grants (e.g., SPS or configured grants) and indicates a set of one or more frequency - hopping patterns.

[0139] At 425, in some aspects, network node 405 may send a second control message to network node 415. The second control message may indicate a specified hopping pattern in a set of one or more hopping patterns indicated by the first control message. In some aspects, the first control message may indicate a mapping between each hopping pattern in the set of one or more hopping patterns and a corresponding sub-band within the BWP. The second control message may be received via the sub-band mapped to the specified hopping pattern, and network node 415 may determine the specified hopping pattern based on the sub-band on which the second control message is received.

[0140] In some other aspects (e.g., type 1 configuration grant or SPS communication), the second control message may be a MAC-CE indicating the specified hopping pattern, which may be different from the default hopping pattern indicated by the first control message. In such cases, network node 415 may communicate via two or more sub-bands according to the default hopping pattern in response to receiving the first control message and before receiving the second control message. Network node 415 may switch to communicating according to the specified hopping pattern in response to the second control message. In some other aspects (e.g., type 2 configuration grant or SPS communication), the second control message may be a DCI that activates a grant in a set of one or more grants and indicates the specified hopping pattern in the set of hopping patterns indicated by the first control message (e.g., one or more bits or fields in the DCI indicate an index or pointer to the specified hopping pattern).

[0141] At 430, network node 405 and network node 415 may communicate via a first sub-band among two or more sub-bands within the BWP configured for network node 405 and network node 415. At 435, network node 405 and network node 415 may switch to communicating via a second sub-band among two or more sub-bands within the BWP according to the specified hopping pattern. In some aspects, network node 405 and network node 415 may communicate via the first sub-band during a first time period before switching to the second sub-band, and the specified hopping pattern may indicate or be associated with the time period. In some aspects, network node 405 and network node 415 may communicate via the first sub-band during a certain number of transmission opportunities based on a first periodicity associated with the first sub-band before switching to the second sub-band based on a second periodicity associated with the second sub-band during a second number of transmission opportunities, and the specified hopping pattern may indicate the first periodicity and the second periodicity and the order for switching between sub-bands or be associated with the first periodicity and the second periodicity and the order for switching between sub-bands.

[0142] Accordingly, network node 405 and network node 415 may communicate via one or more subbands within a BWP according to a specified frequency hopping pattern. Accordingly, network node 415 may support communication via a reduced bandwidth (e.g., subbands) while maintaining frequency diversity and throughput of the communication. By indicating the specified frequency hopping pattern via one or more control messages, network node 405 may improve coordination, throughput, and communication reliability between devices while reducing overhead.

Although the communication manager 820 is illustrated as a separate component, in some aspects, one or more of the functions described with reference to the communication manager 820 may be supported or performed by processor 840, memory 830, code 835, or any combination thereof. For example, code 835 may include instructions executable by processor 840 to cause device 805 to perform aspects of frequency hopping across subbands within a BWP as described herein, or processor 840 and memory 830 may otherwise be configured to perform or support such operations.
