Technical Field

[0003] The present disclosure relates to wireless communications, including techniques for cyclic frequency hopping in sub-band full-duplex time slots. Background Art

[0004] 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 able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may use 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 extended orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication for communication devices, which may be referred to as user equipment (UE). In some wireless communication systems, UE and network nodes may communicate by performing frequency hopping. However, conventional techniques for frequency hopping may cause self-interference at the device, poor communication efficiency or reliability, etc. Summary of the invention

[0005] The described technology relates to improved methods, systems, devices and apparatuses for supporting technology for cyclic frequency hopping in sub-band full-duplex time slots. In general, a device (e.g., a user equipment (UE), a network node, or both) can apply a frequency offset to a first hop (e.g., a first frequency range), a second hop (e.g., a second frequency range), or both. For example, in the case where the first hop or the second hop appears in the downlink portion of a sub-band full-duplex (SBFD) time slot, the device can cyclically apply the difference between the first hop and the second hop to the first hop or the second hop until a threshold is met. In some examples, both hops can fall in the downlink portion, and the device can first find an initial hop position in the uplink portion based on a second time slot associated with the uplink communication (e.g., the second time slot can be configured for uplink communication with the downlink portion), and then apply the offset to the second hop based on the difference between the initial hop and the second hop.

[0006] In some examples, the device may drop the first hop, the second hop, or both. In some cases, the device may be configured with a threshold distance between frequency ranges (e.g., between hops). In some examples, the network node may send control signaling indicating different hop frequencies for the SBFD time slot. A device that applies a frequency offset to the first hop, the second hop, or both may cause the device to communicate uplink data in the uplink portion of the SBFD time slot instead of the downlink portion of the SBFD time slot.

[0046] In some wireless communication systems, a network node may communicate with a user equipment (UE) using full-duplex communication (e.g., concurrent uplink and downlink communications may be performed within the same time resources (such as a time slot, a set of symbol periods, etc.)) or half-duplex communication (e.g., uplink or downlink communications are performed within the same time resources). For example, in a sub-band full-duplex (SBFD) time slot, uplink transmissions and downlink transmissions may share time resources, but may have different frequency allocations in the SBFD time slot. In other words, a SBFD time slot may include an uplink portion and a downlink portion for full-duplex communication in the SBFD time slot.

[0047] In some examples, the wireless communication system may support frequency hopping so that the device can communicate parts of the transmission on different frequencies in a certain time period (e.g., a time slot), which can produce frequency diversity and improve communication reliability. In frequency hopping, the UE can transmit a first part of a physical resource block (PRB) in a first frequency portion of the time slot (e.g., a first hop) and transmit a second part of the PRB in a second frequency portion of the time slot (e.g., a second hop). The first hop and the second hop may be associated with uplink transmissions associated with an uplink time slot. However, performing frequency hopping may cause the UE to be configured to transmit uplink transmissions in the downlink portion of the SBFD time slot. For example, the first hop, the second hop, or both may be configured so that they are scheduled in the downlink portion of the SBFD time slot rather than the uplink portion of the SBFD time slot, which may result in self-interference at the UE, poor communication efficiency or reliability, or increased latency at the UE.

[0048] Thus, the techniques described herein may provide for applying a frequency offset to a first hop, a second hop, or both. For example, where the second hop occurs in a downlink portion of an SBFD timeslot, a device (e.g., a UE, a network node) may cyclically apply the difference between the first hop and the second hop to the second hop, for example until a threshold is met (e.g., the second hop with the applied one or more differences is located within the uplink portion of the SBFD timeslot). Additionally or alternatively, where the first hop occurs in a downlink portion, the device may cyclically apply the difference to the first hop (e.g., applying the difference until one or more instances of the threshold being met). In some examples, both hops may fall in the downlink portion, and the device may first find an initial hop position in the uplink portion based on a second timeslot associated with uplink communication (e.g., the second timeslot may be configured for uplink communication), and then apply the offset to the second hop, as described herein.

[0049] In some examples, applying the frequency offset may include dropping the first hop, the second hop, or both. In some cases, the device may be configured with a threshold distance between frequency ranges (e.g., between hops). In some examples, the network node may send control signaling indicating different hop frequencies for the SBFD time slot. Devices that apply the frequency offset to the first hop, the second hop, or both may cause the device to communicate uplink data in the uplink portion of the SBFD time slot rather than the downlink portion of the SBFD time slot, which may result in increased efficiency and reduced latency, among other potential benefits.

[0050] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are illustrated and described by frequency hopping schemes and process flows. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to techniques for cyclic frequency hopping in sub-band full-duplex time slots.

[0051] Figure 1 An example of a wireless communication system 100 supporting techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (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).

[0052] The network entities 105 may be dispersed throughout a geographic area to form a wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network node 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or a network equipment, among other names. In some examples, the network entity 105 and the UE 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link). For example, the network node 105 may support a coverage area 110 (e.g., a geographic coverage area), and the UE 115 and the network node 105 may establish one or more communication links 125 over the coverage area. The coverage area 110 may be an example of a geographic area, and the network node 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs) over the geographic area.

[0053] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices (e.g., Figure 1 105 or other UEs 115 or network entities 105 shown in FIG.

[0054] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network node 105 (e.g., any network node described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network node 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network node 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network node 105, and the third node may be a network node 105. In yet other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network node 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network node 105, apparatus, device, computing system, etc. as nodes. For example, disclosure that UE 115 is configured to receive information from network node 105 also discloses that the first node is configured to receive information from a second node.

[0055] In some examples, the network entities 105 may communicate with the core network 130, or communicate with each other, or both. For example, the network entities 105 may communicate with the 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, the network entities 105 may communicate with each other over the backhaul communication links 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, 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), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0056] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network node 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network node 105 (e.g., a single RAN node, such as a base station 140).

[0057] In some examples, the network node 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that can be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network node 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, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0058] The functional split between CU 160, DU 165, and RU 175 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, and RU 175. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 communicating over those communication links.

[0059] In some wireless communication systems (e.g., wireless communication system 100), 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 controlled in part by one or more CUs 160 associated with a donor network node 105 (e.g., a donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a collection of independent antennas for relaying communications with the UE 115, or may share the same antenna of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0060] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support the techniques for cyclic frequency hopping in sub-band full-duplex time slots as described herein. For example, some operations described as being performed by a UE 115 or a network node 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0061] 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 a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.

[0062] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0063] UE 115 and network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) on one or more carriers. The term "carrier" may refer to a set of RF spectrum resources with a defined physical layer structure to support communication link 125. For example, a carrier for communication link 125 may include a portion of an RF spectrum band (e.g., bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the 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 the network node 105 and other devices may refer to communication between a device and any part (e.g., entity, sub-entity) of the network node 105. For example, the terms "send," "receive," or "communicate" when referring to the network node 105 may refer to any part of the network node 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0064] In some examples (such as in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be located based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0065] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network node 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network node 105, or both, as well as other transmission configurations. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode).

[0066] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communications over a particular carrier bandwidth or may be configurable to support communications over one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0067] The signal waveform transmitted over the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that the more resource elements a device receives and the higher the order of the modulation scheme, the higher the data rate of the device may be. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0068] One or more parameter sets for a carrier may be supported, where the parameter set may include subcarrier spacing (Δf) and cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0069] The time interval of the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0070] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots including one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating band.

[0071] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., a certain amount of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0072] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0073] The network node 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network node 105 (e.g., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of the network node 105), such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0074] A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. Small cells may be associated with lower power network nodes 105 (e.g., lower power base stations 140) compared to macro cells, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network node 105 may support one or more cells, and may also use one or more component carriers to support communications on one or more cells.

[0075] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0076] In some examples, the network nodes 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network node 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0077] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0078] 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). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency may be used interchangeably herein.

[0079] In some examples, a UE 115 may be able 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 in a group that are performing D2D communication may be within a coverage area 110 of a network node 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured or scheduled by the network node 105. In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network node 105, or may otherwise be unable or not configured to receive transmissions from the network node 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, the network node 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communications may be performed between UEs 115 without involving network node 105 .

[0080] 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 layer (NAS) functions, such as mobility, authentication, and bearer management of 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 transported by a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0081] 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). In general, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is about one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0082] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as network entities 105 and UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a carrier aggregation configuration (e.g., LAA) combined with component carriers operating in licensed bands. Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0083] A network node 105 (e.g., a base station 140, RU 170) or a UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network node 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network node 105 may be located at different geographical locations. The network node 105 may have an antenna array having a set of rows and columns of antenna ports that the network node 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0084] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network node 105, a 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 may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may 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).

[0085] The network node 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network node 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network node 105 along different directions. For example, the network node 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as the network node 105), or by a receiving device (such as the UE 115)) beam directions for later transmission or reception by the network node 105.

[0086] A transmitting device (e.g., transmitting network node 105, transmitting UE 115) may transmit some signals, such as data signals associated with a particular receiving device, along a single beam direction (e.g., a direction associated with a receiving device, such as receiving network node 105 or receiving UE 115). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network node 105 along different directions, and may report to network node 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0087] In some examples, transmission by a device (e.g., by a network node 105 or a UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from the network node 105 to the UE 115) using a combination of digital precoding or beamforming. The 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 a system bandwidth or one or more subbands. The network node 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-faceted codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network node 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0088] 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 receiving device (e.g., network node 105). For example, the receiving device may perform reception according to multiple receiving directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, a receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0089] The wireless communication system 100 can be a packet-based network operated according to a layered protocol stack. In the user plane, the communication at the bearer layer or the PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reorganization to transmit on a logical channel. The MAC layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of the RRC connection for the radio bearer supporting user plane data between the UE 115 and the network node 105 or the core network 130. At the PHY layer, the transport channel can be mapped to the physical channel.

[0090] UE 115 and network entity 105 may support retransmission of data to increase the possibility of successfully receiving data. Hybrid automatic repeat request (HARQ) feedback is a technology for increasing the possibility of correctly receiving data through 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 the throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0091] In some examples, UE 115 and network node 105 can communicate according to a full-duplex configuration, in which a first transmission and a second transmission can occur at the same time resource. For example, a device (e.g., UE 115, network node 105) can concurrently (e.g., in the same time period (such as a time slot or other duration)) send a signal and receive a signal. In some cases, network node 105 and UE 115 can additionally or alternatively communicate according to a half-duplex configuration, in which a device can send a signal on a time resource or alternatively receive a signal on the time resource. In a full-duplex configuration, there can be two types of time slots supporting uplink transmission, such as an uplink time slot (e.g., a half-duplex uplink time slot that can support uplink transmission but does not support downlink transmission) and a sub-band full-duplex (SBFD) time slot that can support both uplink transmission and downlink transmission. For example, in an uplink timeslot, the full frequency range associated with the timeslot may be associated with uplink transmissions and may be regulated by an uplink bandwidth portion (BWP). In another example, in an SBFD timeslot, uplink transmissions and downlink transmissions may share time resources, but may have different frequency allocations in the SBFD timeslot. In some examples, a relatively small portion of a SBFD timeslot (e.g., a limited uplink frequency band) may be associated with uplink transmissions (e.g., used for uplink transmissions), while the downlink portion of the SBFD timeslot may be relatively large.

[0092] In some examples, the wireless communication system 100 may support frequency hopping. Frequency hopping may be an example of a device communicating portions of a transmission on different frequencies to obtain frequency diversity and improve communication reliability. For example, a device may be configured with a certain amount of hopping (e.g., switching from transmitting on a first frequency range to transmitting on a second frequency range within a certain time period (such as a time slot)). Additionally or alternatively, a hop may be an example of or referred to as a frequency range, portions of a frequency band, etc. Frequency hopping may be enabled for certain formats of a physical uplink control channel (PUCCH) associated with an OFDM signal length and a number of bits (e.g., frequency hopping may be enabled for formats 1, 3, and 4 of a physical uplink control channel message, and frequency hopping with two symbols may be enabled using formats 0 and 2). In some examples, the number of symbols in the first hop may be a "floor" (e.g., the total number of PUCCH symbols divided by 2), and the position of the hop may be flexible or follow a mirror mapping, or a combination of the two. As an illustrative example, the PUCCH may support multiple formats (e.g., PUCCH formats 0, 1, 2, 3, and 4), each of which may be associated with a length and number of bits of an OFDM symbol. Intra-slot frequency hopping may be configured for some of these formats (e.g., 1, 3, or 4), and the number of symbols in the first hop (e.g., to be transmitted in a first frequency range) may be signaled or preconfigured at the device for each format.

[0093] In some examples, the UE 115 may be provided with one or more PUCCH resources by higher layers. The PUCCH resources may include one or more parameters, including a PUCCH resource index provided by PUCCH-ResourceID, an index of the first PRB before frequency hopping or for no frequency hopping provided by startingPRB (in the case that useInterlacePUCCH-PUSCH is not provided to the UE in the BWP-UplinkDedicated field), an indication for intra-slot frequency hopping provided by the intraSlotFrequencyHopping field, an index of the first interlace provided by the interlace0 field (in the case that useInterlavePUCCH-PUSCH is provided to the UE in BWP-Uplink dedicated), an index of a resource block (RB) set provided by the rb-SetIndex field, a configuration of the PUCCH format provided by the format field, or any combination thereof.

[0094] As an example, in the case where the PUCCH is associated with a specific range of OFDM symbols (e.g., 4 to 14 OFDM symbols), intra-slot frequency hopping in the PUCCH may be supported, which may allow flexibility in frequency hopping. The UE may perform frequency hopping (e.g., frequency hopping) by sending a first portion of a physical resource block (PRB) in a first frequency portion of the slot (e.g., a first hop) and sending a second portion of the PRB in a second frequency portion of the slot (e.g., a second hop). The first hop and the second hop may be associated with uplink transmissions intended for uplink slots. However, since a small portion of the SBFD slot is associated with uplink transmissions, performing frequency hopping may cause the UE to send the first hop, the second hop, or both in the downlink portion of the SBFD slot rather than the uplink portion of the SBFD slot. For example, the first hop and the second hop may be configured for an uplink slot, but may result in uplink transmissions on the downlink portion of the SBFD slot. In other words, a device that performs frequency hopping using a configured first hop, a second hop, or both in the downlink portion of a SBFD timeslot may cause self-interference, poor communication efficiency or reliability, or increased latency.

[0095] Techniques for applying a frequency offset to a first hop, a second hop, or both are described herein. For example, a device (e.g., a UE 115 or a network node 105 or both) may be configured to discard one or more uplink hops that overlap with the downlink portion of a timeslot (e.g., the applied offset may cause the hop to be moved so that the frequency range of the hop has the same frequency range as another hop located within the uplink portion of the timeslot), the device may be configured to apply one or more offsets to hops located outside the correct portion in a cyclic manner (e.g., until a threshold associated with the hop being offset to fall within the uplink portion is met), or a combination thereof. As an illustrative example, in the case where the second hop occurs in the downlink portion of an SBFD timeslot, the device may cyclically apply the difference between the first hop and the second hop to the second hop (e.g., until the second hop with the applied difference is located within the uplink portion of the SBFD timeslot). In the case where the first hop occurs in the downlink portion, the device may cyclically apply the difference to the first hop. In some examples, both hops can fall within the downlink portion, and the device can first find an initial hop position in the uplink portion based on a second time slot associated with uplink communications (e.g., the second time slot can be configured for uplink communications with the downlink portion), and then cyclically apply an offset to the second hop until both hops fall within the uplink portion.

[0096] In some cases, the device may be configured by the network node with a threshold distance between frequency ranges (e.g., between hops). For example, in the event that the applied offset results in a hop being relatively close to another hop (e.g., less than a threshold distance in frequency), the device may discard the hop or continue to apply the offset until a frequency range that satisfies (e.g., is greater than) the threshold distance is obtained. In some examples, the network node may send control signaling indicating different frequency hopping for SBFD time slots. For example, the control signaling may indicate frequency hopping for an uplink time slot (e.g., a legacy uplink time slot that does not support downlink communications) and frequency hopping for an SBFD time slot. Such techniques may cause the device to communicate uplink data in the uplink portion of an SBFD time slot rather than the downlink portion of the SBFD time slot, which may result in increased efficiency and reduced latency, among other benefits.

[0097] Although described herein with reference to two uplink hops and time slots for clarity of illustration, it should be understood that the techniques described herein may be applied to any number or type of hops (e.g., downlink hops that overlap with an uplink portion), any number or type of time slots or other time periods, or combinations thereof.

[0098] Figure 2 An example of a wireless communication system 200 that supports techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100 and can include a UE 115-a and a network node 105-a having a coverage area 110-a, which can be as described in reference Figure 1 An example of a UE 115 and a network node 105 with a coverage area 110 is depicted. The network node 105-a and the UE 115-a may communicate with each other via a communication link 205 and a communication link 215. For example, the communication link 205 may be an example of an uplink communication link, and the communication link 215 may be an example of a downlink communication link.

[0099] The network node 105-a and the UE 115-a may communicate with each other according to a full-duplex configuration. For example, the network node 105-a may send a downlink signal to the UE 115-a (e.g., via the communication link 215) while simultaneously receiving an uplink signal from the UE 115-a (e.g., via the communication link 205). Additionally or alternatively, the UE 115-a may receive a downlink signal from the network node 105-a (e.g., via the communication link 215) while simultaneously sending an uplink signal to the network node 105-a (e.g., via the communication link 215). In some examples, the UE 115-a and the network node 105-a may use (e.g., as described in reference to Figure 1The UE 115-a and the network node 105-a may transmit and receive messages in the same time resources but different frequency resources. Thus, the downlink resources may be separated from the uplink resources in the frequency domain, as described in reference to Figure 3 Described in more detail.

[0100] The network node 105-a may send configuration information, data, or both to the UE 115-a via the communication link 215. The communication link 215 may be an example of a link for carrying a physical downlink control channel (PDCCH) (e.g., for sending control information) or a physical downlink shared channel (PDSCH) (e.g., for sending data). For example, the network node 105-a may send a frequency hopping configuration 220 to the UE 115-a to indicate a frequency range of a first hop 210-a of PRBs and a frequency range of a second hop 210-b of PRBs. Based on the frequency hopping configuration 220, the UE 115-a may send the first hop 210-b and the second hop 210-b (e.g., perform frequency hopping thereon) during a portion of the SBFD timeslot. However, in some examples, performing frequency hopping may cause UE 115-a to transmit the first hop 210-a, the second hop 210-b, or both in the downlink portion of the SBFD time slot rather than in the uplink portion of the SBFD time slot, which may result in self-interference, poor communication efficiency or reliability, or increased latency at UE 115-a.

[0101] As described herein, the wireless communication system 200 may support the use of techniques that enable the UE 115-a, the network node 105-a, or both to apply a frequency offset to a first hop 210-a, a second hop 210-b, or both, when the corresponding frequency hop 210 is configured to transmit during the downlink portion of the SBFD time slot. In some examples, the network node 105-a may configure a frequency offset for the first hop (e.g., a third frequency range), a frequency offset for the second hop (e.g., a fourth frequency range), or both via the communication link 215. In some examples, the UE 115-a may apply a frequency offset to the first hop 210-a, the second hop 210-b, or both based on whether the frequency hop is configured to transmit in the downlink portion of the SBFD time slot. UE 115-a may determine the frequency offset by calculating a difference between a first hop 210-a and a second hop 210-b, a difference between the first hop 210-a and a first resource block index (e.g., a difference between a starting resource block index of an uplink time slot that does not support full-duplex communication and a starting physical resource block index of an SBFD time slot), or both. Applying a frequency offset may result in reduced latency and increased reliability because the frequency hop 210 may maintain the uplink portion of the SBFD time slot due to the frequency offset. In some examples, applying a frequency offset may refer to dropping a hop 210 for a downlink portion and sending an uplink transmission on a different hop 210 within the uplink portion, or an example thereof.

[0102] In some examples, network node 105-b may configure UE 115-a to have a threshold distance (e.g., a minimum distance between frequency ranges) for first hop 210-a and second hop 210-b. The device may determine whether the calculated difference satisfies the threshold, and if the difference fails to satisfy the threshold, the device may refrain from performing frequency hopping (e.g., the device may discard hops that fail to satisfy the threshold after applying the frequency offset). As an illustrative example, such as when the device disables frequency hopping, the device may communicate all symbols in the PRB in the first hop 210-a (e.g., if the second hop 210-a falls in the downlink portion of the time slot).

[0103] Figure 3 An example of a frequency hopping scheme 300 that supports techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. In some examples, the frequency hopping scheme 300 can implement aspects of wireless communication systems 100 and 200. For example, a UE (e.g., as described in reference Figure 1 and Figure 2 UE 115 as described in reference Figure 1 and Figure 2The described network node 105 or both) may implement a frequency hopping scheme 300 for full-duplex communication. The frequency hopping scheme 300 may represent a set of time and frequency resources for communication between the UE 115 and the network node 105.

[0104] The frequency hopping scheme 300 may include, for example, one or more time slots 330 (e.g., time slot 330-a and time slot 330-b) and time slots 335 (e.g., time slot 335-a and time slot 335-b). The time slots 330 may include an uplink portion (e.g., uplink data region 325) for uplink transmissions from a UE to a network node, from a network node to another network node, etc., as described herein with reference to Figure 1 As described herein. Timeslot 335 may include an uplink data region 325 of one or more uplink transmissions and a downlink portion (e.g., downlink data region 310) of one or more downlink transmissions, respectively. For example, timeslot 335 may be an example of an SBFD timeslot as described herein, which may support concurrent uplink communications (e.g., in uplink portions 320 and 325) and downlink communications (e.g., downlink portions 305 and 310) in the same timeslot. In some examples, uplink portions and downlink portions may additionally or alternatively be referred to as regions, subbands, etc. PRB 315 may be an example of resources allocated for uplink transmissions according to a frequency hopping configuration.

[0105] Each time slot 330 and each time slot 335 may include a corresponding resource allocation in the frequency domain. For example, a time slot 335 may include multiple resource blocks (e.g., PRBs 315). In some examples, one or more time slots 335 may be associated with a frequency hopping pattern (e.g., inter-time slot hopping, intra-time slot hopping). In such examples, the frequency of the transmission may vary within or across time slots 335 (e.g., one or more frequency ranges may be used for transmissions in or across these time slots). Each time slot 330 and time slot 335 may be configured according to the type of communication. For example, time slots 330-a and 330-b may be configured for half-duplex communication (e.g., communication in the uplink direction or the downlink direction), wherein time slots 330-a and time slots 330-b may include uplink data transmissions in the uplink data region 325 (e.g., transmissions via the physical uplink shared channel (PUSCH) of the PRBs 315) and the uplink control region 320. In another example, time slots 335-a and 335-b may be configured for full-duplex communication (e.g., supporting simultaneous communication in both the uplink direction and the downlink direction). For example, time slots 335-a and time slots 335-b may include a downlink control region 305, a corresponding downlink data region 310, an uplink control region 320, and a corresponding uplink data region 325. Figure 3In the example of , such a duration supporting both uplink and downlink communications may be represented as 'D+U'.

[0106] UE 115 may perform frequency hopping by sending a first hop and a second hop. For example, UE 115 may send a first portion of an uplink transmission on PRB 315-a and a second portion of the uplink transmission on PRB 315-b in the uplink data region 325 of time slot 330-a. In some examples, the location of PRB 315 (e.g., hop, frequency range) may be configured via control signaling from network node 105. For example, network node 105 may indicate the frequency hopping configuration in a PUCCH message, as described herein with reference to Figure 1 and Figure 2 In some examples, PRB 315-e may be referred to as the starting PRB 315 for time slot 335-a, and PRB 315-c may be referred to as the second hop PRB 315 for time slot 335-a (eg, before applying an offset as described herein).

[0107] However, in some examples, the frequency hopping configuration for time slot 330 may result in inefficient communication or self-interference in time slot 335. For example, UE 115 may be configured to transmit uplink PRB 315-c in downlink data region 310 of time slot 335-a (e.g., because PRB 315-b in time slot 330-a is indicated as the same frequency range). In other words, PRB 315-c, PRB 315-e, or both may be configured so that they are scheduled in downlink data region 310 of time slot 335-a instead of uplink data region 325. In this example (e.g., frequency hopping scheme 300), PRB 315-c (e.g., second hop) may appear in downlink data region 310 of time slot 335-a.

[0108] According to the techniques described herein, a device may apply an offset to a hop in a downlink data region 310 (e.g., a downlink portion) of a time slot 335-a. For example, PRB 315-c may appear in the downlink data region 310 of time slot 335-a, and the device may apply a difference (e.g., an offset) to obtain another frequency range (e.g., a third frequency range for PRB 315-d) that satisfies a threshold (e.g., located in the uplink data region 325). In some examples, the device may determine the difference between the scheduled PRBs 315 (e.g., the difference in frequency or index of PRB 315-e and PRB 315-c) and use the difference as an offset applied in a positive or negative direction. In other words, the UE 115 may apply the difference between the starting PRB 315 and the second hop PRB 315 to one or two PRBs 315 in a cyclic manner to stay in the uplink subband.

[0109] The device may apply the offset cyclically until a threshold is met. For example, the device may apply the offset to PRB 315-c (e.g., once or multiple times) until PRB 315-c is located within the uplink data region 325 (e.g., PRB 315-d). In the event that the threshold is not met, the difference may be applied again until the threshold is met (e.g., PRB 315-c adjusted by the offset is within the uplink portion). In the event that the application of the difference extends beyond the frequency band, the position of the resulting PRB may be cyclic. For example, in the case where the difference is applied in the positive direction instead of the resulting frequency range being located Figure 3 In the case where the frequency band is above the example, the frequency range can be cycled to Figure 3 The bottom of the frequency band in , and vice versa in the case where the difference is applied in the negative direction. Such a cycle may be an example of applying the offset cyclically (eg, in a cyclic manner).

[0110] In some examples, UE 115 may drop PRB 315-c. In other words, UE 115 may disable frequency hopping for one or more PRBs 315 and may send uplink information in the frequency range of PRB 315-e (e.g., the hop frequency initially located within uplink data region 325) for the duration of time slot 335-a.

[0111] In some examples, by configuring the device to apply a frequency offset (e.g., discarding PRB 315-c hops, cyclically shifting them to the uplink data region 325), the device can be enabled to identify the PRB 315-d frequency range for communication without signaling, which can result in reliable communication (e.g., since uplink data is communicated in the downlink data region 310, the possibility of self-interference at either device is reduced), relatively low signaling overhead, or both. Additionally or alternatively, the device can be configured with both a frequency hopping configuration for time slot 330 and a second frequency hopping configuration for time slot 335. For example, the hops for uplink time slot 330 can have a first configuration, and the message configuring the first configuration or another message can indicate a second configuration for the hops in time slot 335 (e.g., the frequency ranges of PRB 315-e and PRB 315-d or other frequency ranges can be indicated by the second configuration), which can provide scheduling flexibility and other benefits.

[0112] In some cases, the device may be configured with a threshold distance between frequency ranges (e.g., between hops). For example, the network node may indicate the threshold in a message, or the device may be preconfigured with the threshold. In some examples, in the event that the difference between PRB 315-d (resulting from applying an offset more to PRB 315-c) and PRB 315-e fails to meet the threshold distance (e.g., the frequency ranges are relatively close together), the device may discard PRB 315-d (e.g., disable frequency hopping and send uplink transmissions in the frequency range of PRB 315-e). In some examples, aspects of the frequency hopping scheme may implement aspects of, or be implemented by, any of the wireless communication systems, frequency hopping schemes, and process flows described herein.

[0113] Although described herein with reference to two uplink hops for clarity of illustration, it should be understood that the techniques described herein may be applied to any number or type of hops (e.g., downlink hops overlapping with an uplink portion), any number or type of time slots or other time periods, or combinations thereof. For example, a downlink hop falling in the uplink portion of an SBFD time slot 335 may be shifted to the downlink portion as described herein. Furthermore, operations described as being performed by a UE 115 may additionally or alternatively be performed by a network node 105, and vice versa.

[0114] Figure 4 An example of a frequency hopping scheme 400 that supports techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. In some examples, the frequency hopping scheme 400 can implement or be implemented by aspects of wireless communication systems 100 and 200, the frequency hopping scheme 300, or a combination thereof. For example, a device (e.g., as described in reference Figure 1 and Figure 2 UE 115 as described in reference Figure 1 and Figure 2 The described network node 105 or both) may implement a frequency hopping scheme 400 for full-duplex communication. The frequency hopping scheme 400 may represent a set of time and frequency resources for communication between the UE 115 and the network node 105.

[0115] The frequency hopping scheme 400 may implement or be implemented by aspects of the frequency hopping scheme 300. For example, the frequency hopping scheme 400 may include one or more time slots 430 (e.g., as described in reference Figure 3 The time slot 330 described above) and the time slot 435 (e.g., as described in reference Figure 3 The time slot 430 may be associated with an uplink data region 425 for uplink transmissions. The time slot 435 may be associated with one or more uplink data regions 425 for uplink transmissions (e.g., as described in reference to Figure 3 The uplink data region 325 described above) and the downlink data region 410 for one or more downlink transmissions (e.g., as described in reference Figure 3 The downlink transmission may include a downlink control region 405 (e.g., as described in reference Figure 3 Similarly, an uplink transmission may include an uplink control region 320 (e.g., as described in reference Figure 3 The downlink control region 405 and the uplink control region 420 may include resources allocated in the time domain and resources allocated in the frequency domain. The uplink transmission may be associated with the PRB 415 (e.g., as described in reference Figure 3 PRB 315) described herein is associated with.

[0116] UE 115 may perform frequency hopping by sending a first uplink PRB 415 and a second uplink PRB 415 (e.g., hopping). For example, UE 115 may send PRB 415-a and PRB 415-b in the uplink data region 425 of time slot 430-a. Additionally or alternatively, UE 115 may be configured to perform frequency hopping to send PRB 415-c and PRB 415-e in time slot 435-b. In some examples, UE 115 may be configured to transmit uplink PRB 415 in the downlink data region 410 of time slot 435-a. In this example, PRB 415-c (e.g., the first hop) may appear in the downlink data region 410 of time slot 445-a instead of the uplink data region 425.

[0117] Thus, in the case where PRB 415-c appears in the downlink data region 410 of time slot 435-a, UE 115 can apply the difference (e.g., a negative offset or a positive offset) by determining the difference between PRB 415-e and PRB 415-c. UE 115 can cyclically apply the negative offset until a threshold is met. For example, UE 115 can apply the negative offset to PRB 415-c (e.g., once or multiple times) until PRB 415-c is located within the uplink data region 425 (e.g., PRB 415-d). In some examples, UE 115 can discard PRB 415-c. UE 115 can disable frequency hopping and can send uplink information in PRB 415-e (e.g., a frequency hopping that was initially located within the uplink data region 425).

[0118] In some cases, UE 115 may be configured with a threshold distance between hops by network node 105. In some examples, network node 105 may send control signaling indicating different hopping frequencies for time slot 435. Application of a frequency offset by UE 115 to PRB 415-c (e.g., a first hop) may cause UE 115 to communicate uplink data in uplink data region 425 of time slot 435-a rather than in downlink data region 410 of time slot 435-a.

[0119] Figure 5 An example of a frequency hopping scheme 500 that supports techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. In some examples, the frequency hopping scheme 500 can implement or be implemented by aspects of wireless communication systems 100 and 200, frequency hopping schemes 300 and 400, or a combination thereof. For example, a device (e.g., as described in reference Figure 1 and Figure 2 UE 115 as described in reference Figure 1 and Figure 2 The described network node 105 or both) may implement a frequency hopping scheme 500 for full-duplex communication. The frequency hopping scheme 500 may represent a set of time and frequency resources for communication between the UE 115 and the network node 105.

[0120] The frequency hopping scheme 500 may implement aspects of the frequency hopping schemes 300 and 400. For example, the frequency hopping scheme 500 may include one or more time slots 530 (e.g., as described in reference Figure 3 and Figure 4 The time slots 330 and 430 described above) and the time slot 535 (e.g., as described in reference Figure 3 and Figure 4The time slot 530 may be associated with an uplink data region 525 for uplink transmissions. The time slot 535 may be associated with one or more uplink data regions 525 for uplink transmissions (e.g., as described in reference to Figure 3 and Figure 4 The uplink data regions 325 and 425 described above) and the downlink data region 510 for one or more downlink transmissions (e.g., as described in reference Figure 3 and Figure 4 The downlink transmission may include a downlink control region 505 (e.g., as described in reference to Figure 3 and Figure 4 Similarly, an uplink transmission may include an uplink control region 520 (e.g., as described with reference to Figure 3 and Figure 4 The downlink control region 505 and the uplink control region 520 may include resources allocated in the time domain and resources allocated in the frequency domain. The uplink transmission may be associated with the PRB 515 (e.g., as described in reference Figure 3 and Figure 4 The PRBs 315 and 415 described are associated.

[0121] UE 115 may perform frequency hopping by sending a first uplink PRB 515 (e.g., a first hop) and a second uplink PRB 515 (e.g., a second hop) on an SBFD time slot 535 and an uplink time slot 530. UE 115 may send PRB 515-a and PRB 515-b in the uplink data region 525 of time slot 530-a. In some examples, UE 115 may be configured to transmit two uplink PRBs 515 in the downlink data region 510 of time slot 435-a (e.g., the hop configuration for time slot 530 may cause the hop of time slot 535 to appear in the downlink portion). In this example, PRB 515-c (e.g., a first hop) and PRB 515-e (e.g., a second hop) may both appear in the downlink data region 510 of time slot 535-a instead of the uplink data region 525. That is, in Figure 5 In the example of , both hops may occur outside the uplink portion.

[0122] Thus, the device may be configured to apply an offset (e.g., drop one or more PRBs, shift one or more PRBs, or both) as described herein. For example, where PRB 515-c and PRB 515-e are scheduled to appear in the downlink data region 510 of time slot 535-a, UE 115 may identify the new location of the first hop (e.g., PRB 515-d) that falls within the uplink portion and cyclically apply the difference to the second hop (e.g., PRB 515-e) to drop PRB 515-e or obtain PRB 515-f, as described herein.

[0123] As an illustrative example, the UE 115 may use one or more block indices to identify an initial frequency range for the time slot 535-a (e.g., a first hop for the SBFD time slot 535-a). For example, the UE 115 may determine the difference between the starting PRB index of the time slot 535-a (e.g., a first index, an initial index of the uplink data region 525) and the starting PRB index of the time slot 530-a (e.g., a first index, an initial index of the uplink data region 525 in the time slot 530-a). Such an index may be an example of a frequency range in a frequency band or subband or correspond to a frequency range in a frequency band or subband. As described herein, the UE 115 may apply the difference to (e.g., add or subtract) the first resource block index in the time slot 535-a in a cyclic manner (e.g., until a threshold is met and, as an example, PRB 515-d is obtained). As an illustrative example, the UE 115 may use Equation 1 to obtain the initial hop for the time slot 535-a:

[0125] In Equation 1, Starting.PRB.SBFD may represent the initial PRB 515 for the SBFD time slot 535-a (e.g., PRB 515-d for the first hop as a result of Equation 1), first.PRB.SBFD.slot may represent the first PRB 515-c hop of the time slot 535-a before the offset is applied, starting.PRB.legacy may represent the initial PRB 515 of the time slot 530-a (e.g., the first index of the frequency band of the time slot 530-a), first.PRB.legacy.slot may represent the first PRB 515-a of the first hop of the time slot 530-a having a time slot type different from the time slot 535-a (e.g., a legacy time slot type), and N.SBFD may represent the total number of PRBs 515 in the time slot 535-a (e.g., the number of PRB indices for the uplink portion of the time slot 535-a for the entire frequency band).

[0126] Additionally or alternatively, the UE 115 may apply an offset to the PRB 515-e (e.g., the second hop) by determining the difference between the PRB 515-d and the PRB 515-e. The UE 115 may apply the offset cyclically until a threshold is met. For example, the UE 115 may apply the offset to the PRB 515-e until the PRB 515-e is located within the uplink data region 525 (e.g., PRB 515-f). In some examples, the UE 115 may discard PRB 515-c and PRB 515-e. In other words, in order to find the second hop PRB 515-f, the UE 115 may apply the second hop PRB 515 (e.g., PRB 515-e) to the starting PRB in the SBFD slot 535 (e.g., PRB 515-d obtained as described herein) in a cyclic manner. As an illustrative example, UE 115 may use Equation 2 to obtain the second hop PRB for time slot 535-a:

[0127]

[0128] In Equation 2, Second.Hop.PRB.SBFD may represent PRB 515-f (e.g., PRB 515-f may be the result of the second hop of time slot 535-a as a result of Equation 2), starting.PRB.SBFD may represent the first PRB 515 hop of time slot 535-a after Equation 1 (e.g., PRB 515-d), second.hop.PRB may represent the second hop of time slot 535-a before applying Equation 2 (e.g., PRB 515-e), and N.SBFD may represent the total number of PRBs 515 in time slot 535-a (e.g., the number of PRB indices for the uplink portion of time slot 535-a for the entire frequency band).

[0129] In some cases, UE 115 may be configured by network node 105 with a threshold distance between hops, as described herein. In some examples, network node 105 may send control signaling indicating different hopping frequencies for time slot 535 and time slot 530, as described herein with reference to Figures 2 to 4 UE 115 applying frequency offset to PRB 515-c (e.g., first hop) and PRB 515-e (e.g., second hop) may cause UE 115 to communicate uplink data in uplink data region 525 of time slot 535-a instead of in downlink data region 510 of time slot 535-a.

[0130] In some examples, although Figures 3 to 5The various frequency hopping schemes of the present invention describe exemplary techniques for applying an offset, but other techniques may be used in addition or alternatively. For example, the device may use the difference between PRBs to cyclically apply the offset, the device may be configured with a value for the offset (e.g., preconfigured or configured via control signaling), and a default (e.g., fallback) hopping position may be configured for time slot 535 or time slot 530, or any combination thereof.

[0131] Figure 6 An example of a process flow 600 that supports techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 600 can implement aspects of the wireless communication systems 100 and 200, the frequency hopping schemes 300, 400, and 500, or any combination thereof. For example, the process flow 600 can include a UE 115-b and a network node 105-b, which can be examples of corresponding devices described herein.

[0132] In the following description of process flow 600, operations between UE 115-b and network node 105-b may be sent in a different order than shown, or operations performed by UE 115-b and network node 105-b may be performed in a different order or at a different time. Some operations may also be omitted from process flow 600, or other operations may be added to process flow 600. It should be understood that although UE 115-b and network node 105-b are shown as performing multiple operations of process flow 600, any wireless device may perform the operations shown.

[0133] At 605, network node 105-b may send a message to UE 115-b. The message may indicate at least a first frequency range for uplink data and a second frequency range for the uplink data. In some examples, the message may indicate a third frequency range, a fourth frequency range, or both for sending uplink data during a sub-band full-duplex duration. In some examples, the message at 605 may indicate that network node 105-b supports (e.g., applies, configures UE 115-b to apply) the frequency hopping techniques described herein. Additionally or alternatively, the message may be sent in response to UE 115-b indicating an ability to support the frequency hopping techniques described herein.

[0134] At 610, in some examples, the UE 115-b, the network node 105-b, or both may identify an overlap of the first frequency range, the second frequency range, or both with the downlink portion of the sub-band full-duplex duration. Figures 1 to 5 As described, the first hop, the second hop, or both, for uplink communications may overlap with the downlink portion of the SBFD timeslot.

[0135] At 615, in some examples, UE 115-b, network node 105-b, or both may drop the first frequency range or the second frequency range based on the first frequency range or the second frequency range overlapping the downlink portion of the sub-band full-duplex duration. In some examples, dropping the frequency range may be an example of applying an offset or may be referred to as applying an offset (e.g., such that transmissions on the dropped frequency range are instead sent on a frequency range that is not dropped).

[0136] At 620, in some examples, the UE 115-b, the network node 105-b, or both may apply a frequency offset to at least one of the first frequency range or the second frequency range, as described herein with reference to Figures 1 to 5 Described. UE 115-b, network node 105-b, or both may apply a frequency offset based on the first frequency range, the second frequency range, or both overlapping with the downlink portion of the sub-band full-duplex duration. In some cases, UE 115-b, network node 105-b, or both may apply a frequency offset to the second frequency range based on the second frequency range overlapping with the downlink portion of the sub-band full-duplex duration. UE 115-b may apply a frequency offset to the first frequency range based on the first frequency range overlapping with the downlink portion of the sub-band full-duplex duration. In some cases, UE 115-b may apply a difference between the first frequency range and the second frequency range to the first frequency range, the second frequency range, or both.

[0137] In some cases, UE 115-b, network node 105-b, or both may apply a second difference between the first frequency range and the second frequency range to the first frequency range, the second frequency range, or both. In some cases where both the first frequency range and the second frequency range overlap with the downlink portion of the sub-band full-duplex duration, UE 115-b, network node 105-b, or both may identify an initial frequency range for the sub-band full-duplex duration based on an initial index of a duration before the sub-band full-duplex duration, an initial index of the sub-band full-duplex duration, or a difference between the first frequency range and the duration before the sub-band full-duplex duration. UE 115-b, network node 105-b, or both may apply a frequency offset to the second frequency range based on the difference between the initial frequency range and the second frequency range.

[0138] At 625, in some examples, the UE 115-b, the network node 105-b, or both may determine whether the applied difference satisfies a threshold, as described herein with reference to Figures 1 to 5The threshold may indicate that the frequency range associated with the applied difference fails to overlap with the downlink portion of the sub-band full-duplex duration. In some cases, the UE 115-b, the network node 105-b, or both may select a third frequency range for sending uplink data based on the applied difference satisfying the threshold.

[0139] The UE 115-b, the network node 105-b, or both may determine whether to apply the second difference to the first frequency range, the second frequency range, or both based on the applied difference failing to meet the threshold. In some cases, the UE 115-b, the network node 105-b, or both may determine whether the applied frequency offset meets a threshold distance between the first frequency range and the third frequency range or a second threshold distance between the second frequency range and the third frequency range. The third frequency range may be a result of applying the frequency offset to the first frequency range or the second frequency range. The UE 115-b, the network node 105-b, or both may discard at least the third frequency range based on the frequency offset failing to meet the threshold distance.

[0140] At 630, in some examples, UE 115-b may send uplink data in the first frequency range during the first portion of the sub-band full-duplex duration. In one example, UE 115-b may send uplink data in the first frequency range during the first duration of the sub-band full-duplex duration based on UE 115-b, network node 105-b, or both dropping the first frequency range.

[0141] At 635, in some examples, UE 115-b may send uplink data in the second frequency range during the first portion of the sub-band full-duplex duration. In one example, UE 115-b may send uplink data in the second frequency range during the first duration of the sub-band full-duplex duration based on UE 115-b, network node 105-b, or both dropping the second frequency range.

[0142] At 640, in some examples, UE 115-b may send uplink data in the third frequency range during the first portion of the sub-band full-duplex duration. UE 115-b may send the uplink data based on applying the frequency offset to the first frequency range. In some cases, UE 115-b may send uplink data in the initial frequency range and the third frequency range based on applying the frequency offset.

[0143] At 645, in some examples, UE 115-b may send uplink data in the fourth frequency range during the first portion of the sub-band full-duplex duration. UE 115-b may send the uplink data based on applying the frequency offset to the second frequency range.

[0171] Fig.10A diagram of a system 1000 including a device 1005 supporting techniques for cyclic frequency hopping in sub-band full-duplex time slots according to one or more aspects of the present disclosure is shown. The device 1005 may be an example of a device 705, a device 805, or a UE 115 as described herein or include components thereof. The device 1005 may communicate (e.g., wirelessly) with one or more network entities 105, one or more UEs 115, or any combination thereof. The device 1005 may include components for two-way voice and data communications, including components for sending and receiving communications, such as a communication manager 1020, an input / output (I / O) controller 1010, a transceiver 1015, an antenna 1025, a memory 1030, a code 1035, and a processor 1040. These components may be electronically communicated or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more buses (e.g., a bus 1045).

[0172] I / O controller 1010 can manage input and output signals for device 1005. I / O controller 1010 can also manage peripheral devices that are not integrated into device 1005. In some cases, I / O controller 1010 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 1010 can utilize an operating system, such as or another known operating system. Additionally or alternatively, I / O controller 1010 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device. In some cases, I / O controller 1010 may be implemented as part of a processor (such as processor 1040). In some cases, a user may interact with device 1005 via I / O controller 1010 or via hardware components controlled by I / O controller 1010.

[0173] In some cases, the device 1005 may include a single antenna 1025. However, in some other cases, the device 1005 may have more than one antenna 1025, which may be capable of concurrently transmitting or receiving multiple wireless transmissions.

For example, the transceiver 1015 may represent a wireless transceiver and may communicate bidirectionally with another wireless transceiver. The transceiver 1015 may also include a modem for: modulating packets; providing the modulated packets to one or more antennas 1025 for transmission; and demodulating packets received from one or more antennas 1025.

[0174] The memory 1030 may include random access memory (RAM) and read-only memory (ROM). The memory 1030 may store computer-readable, computer-executable code 1035 including instructions that, when executed by the processor 1040, cause the device 1005 to perform various functions described herein.
