Title: Flexible bandwidth part frequency offset configuration

Description:
FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for flexible bandwidth part frequency offset configuration. 
     BACKGROUND 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). 
     A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

     Several aspects of telecommunication systems are presented with reference to various apparatuses and techniques. These apparatuses and techniques are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G). 
       FIG.  1    is a diagram illustrating an example of a wireless network  100 , in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network  100  may include one or more base stations  110  (shown as a BS  110   a , a BS  110   b , a BS  110   c , and a BS  110   d ), a user equipment (UE)  120  or multiple UEs  120  (shown as a UE  120   a , a UE  120   b , a UE  120   c , a UE  120   d , and a UE  120   e ), and/or other network entities. A base station  110  is an entity that communicates with UEs  120 . A base station  110  (sometimes referred to as a base station (BS)) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station  110  may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station  110  and/or a base station subsystem serving this coverage area, depending on the context in which the term is used. 
     A base station  110  may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs  120  with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs  120  with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs  120  having association with the femto cell (e.g., UEs  120  in a closed subscriber group (CSG)). A base station  110  for a macro cell may be referred to as a macro base station. A base station  110  for a pico cell may be referred to as a pico base station. A base station  110  for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in  FIG.  1   , the BS  110   a  may be a macro base station for a macro cell  102   a , the BS  110   b  may be a pico base station for a pico cell  102   b , and the BS  110   c  may be a femto base station for a femto cell  102   c . A base station may support one or multiple (e.g., three) cells. 
     In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station  110  that is mobile (e.g., a mobile base station). In some examples, the base stations  110  may be interconnected to one another and/or to one or more other base stations  110  or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     The wireless network  100  may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station  110  or a UE  120 ) and send a transmission of the data to a downstream station (e.g., a UE  120  or a base station  110 ). A relay station may be a UE  120  that can relay transmissions for other UEs  120 . In the example shown in  FIG.  1   , the BS  110   d  (e.g., a relay base station) may communicate with the BS  110   a  (e.g., a macro base station) and the UE  120   d  in order to facilitate communication between the BS  110   a  and the UE  120   d . A base station  110  that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. 
     The wireless network  100  may be a heterogeneous network that includes base stations  110  of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations  110  may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network  100 . For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts). 
     A network controller  130  may couple to or communicate with a set of base stations  110  and may provide coordination and control for these base stations  110 . The network controller  130  may communicate with the base stations  110  via a backhaul communication link. The base stations  110  may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. 
     The UEs  120  may be dispersed throughout the wireless network  100 , and each UE  120  may be stationary or mobile. A UE  120  may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE  120  may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium. 
     Some UEs  120  may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs  120  may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs  120  may be considered a Customer Premises Equipment. A UE  120  may be included inside a housing that houses components of the UE  120 , such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. 
     In general, any number of wireless networks  100  may be deployed in a given geographic area. Each wireless network  100  may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. 
     In some examples, two or more UEs  120  (e.g., shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (e.g., without using a base station  110  as an intermediary to communicate with one another). For example, the UEs  120  may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     Devices of the wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network  100  may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. 
     The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band. 
     With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     In some aspects, a network node (e.g., the UE  120 ) may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may receive signaling identifying a configuration for a first bandwidth part, wherein the configuration for the first bandwidth part comprises a first central frequency for the first bandwidth part; and communicate using a second bandwidth part associated with a second central frequency that is offset from the first central frequency by a configured offset. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     In some aspects, a network node (e.g., the base station  110 ) may include a communication manager  150 . As described in more detail elsewhere herein, the communication manager  150  may transmit signaling identifying a configuration for a first bandwidth part, wherein the configuration for the first bandwidth part comprises a first central frequency for the first bandwidth part; and communicate using a second bandwidth part associated with a second central frequency that is offset from the first central frequency by a configured offset. Additionally, or alternatively, the communication manager  150  may perform one or more other operations described herein. 
     As used herein, a network node may refer to any UE, base station, apparatus, device, or computing system configured to perform any techniques described herein. For example, a network node may be a UE. As another example, a network node may be a base station. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE and the second network node may be a base station. Similarly, a third network node may be a UE, a base station, or another device. In some aspects of this example, first, second, and third network nodes may be the same type of device or different types of devices. Similarly, reference to a UE, base station, apparatus, device, or computing system may include disclosure of the UE, base station, apparatus, device, or computing system being a network node. For example, disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. In this example, consistent with this disclosure, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, or a first computing system configured to receive the information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, or a second computing system. 
     As indicated above,  FIG.  1    is provided as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIG.  2    is a diagram illustrating an example  200  of a base station  110  in communication with a UE  120  in a wireless network  100 , in accordance with the present disclosure. The base station  110  may be equipped with a set of antennas  234   a  through  234   t , such as T antennas (T≥1). The UE  120  may be equipped with a set of antennas  252   a  through  252   r , such as R antennas (R≥1). 
     At the base station  110 , a transmit processor  220  may receive data, from a data source  212 , intended or otherwise destined for the UE  120  (or a set of UEs  120 ). The transmit processor  220  may select one or more modulation and coding schemes (MCSs) for the UE  120  based at least in part on one or more channel quality indicators (CQIs) received from that UE  120 . The base station  110  may process (e.g., encode and modulate) the data for the UE  120  based at least in part on the MCS(s) selected for the UE  120  and may provide data symbols for the UE  120 . The transmit processor  220  may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor  220  may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems  232  (e.g., T modems), shown as modems  232   a  through  232   t . For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem  232 . Each modem  232  may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem  232  may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems  232   a  through  232   t  may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas  234  (e.g., T antennas), shown as antennas  234   a  through  234   t.    
     At the UE  120 , a set of antennas  252  (shown as antennas  252   a  through  252   r ) may receive the downlink signals from the base station  110  and/or other base stations  110  and may provide a set of received signals (e.g., R received signals) to a set of modems  254  (e.g., R modems), shown as modems  254   a  through  254   r . For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem  254 . Each modem  254  may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem  254  may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from the modems  254 , may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE  120  to a data sink  260 , and may provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE  120  may be included in a housing  284 . 
     The network controller  130  may include a communication unit  294 , a controller/processor  290 , and a memory  292 . The network controller  130  may include, for example, one or more devices in a core network. The network controller  130  may communicate with the base station  110  via the communication unit  294 . 
     One or more antennas (e.g., antennas  234   a  through  234   t  and/or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples.

In some examples, the memory  242  and/or the memory  282  may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station  110  and/or the UE  120 , may cause the one or more processors, the UE  120 , and/or the base station  110  to perform or direct operations of, for example, process  600  of  FIG.  6   , process  700  of  FIG.  7   , and/or other processes as described herein.

The example  300  of  FIG.  3 A  includes a UE1  302  and two base stations (e.g., TRPs)  304 - 1 ,  304 - 2 , where the UE1  302  is sending uplink (UL) transmissions to base station  304 - 1  and is receiving downlink (DL) transmissions from base station  304 - 2 . In the example  300  of  FIG.  3 A , FD is enabled for the UE1  302 , but not for the base stations  304 - 1 ,  304 - 2 . The example  310  of  FIG.  3 B  includes two UEs, shown as UE1  302 - 1  and UE2  302 - 2 , and a base station  304 , where the UE1  302 - 1  is receiving a DL transmission from the base station  304  and the UE2  302 - 2  is transmitting an UL transmission to the base station  304 .

In the example  320  of  FIG.  3 C , FD is enabled for both the UE1  302  and the base station  304 . 
     As indicated above,  FIGS.  3 A- 3 C  are provided as one or more examples. Other examples may differ from what is described with regard to  FIGS.  3 A- 3 C . 
       FIG.  4    is a diagram illustrating examples  400 ,  405 , and  410  of FD communication in a wireless network, in accordance with the present disclosure. FD communication in a wireless network refers to simultaneous bi-directional communication between devices in the wireless network. For example, a UE operating in a full-duplex mode may transmit uplink communications and receive downlink communications at the same time (e.g., in the same slot). In contrast, half-duplex (HD) communication in a wireless network refers to unidirectional communications (e.g., downlink or uplink communication) between devices at a given time (e.g., in a given slot). 
     As shown in  FIG.  4   , examples  400  and  405  show examples of in-band full-duplex (IBFD) communication. In IBFD, a UE may transmit uplink communications to a base station and receive downlink communications from the base station on the same time and frequency resources. As shown in example  400 , in IBFD, the time and frequency resources for uplink communication may fully overlap with the time and frequency resources for downlink communication. Hence, as illustrated in example  400 , in the box labeled UL (uplink), both uplink and downlink communications may be performed simultaneously. As shown in example  405 , in IBFD, the time and frequency resources for uplink communication may partially overlap with the time and frequency resources for downlink communication. 
     As further shown in  FIG.  4   , example  410  shows an example of sub-band full-duplex (SBFD) communication, which may also be referred to as “flexible duplex.” In SBFD, a UE may transmit uplink communications to a base station and receive downlink communications from the base station at the same time, but on different frequency resources (within the same band). For example, the different frequency resources may be sub-bands of a frequency band such as a time division duplexing (TDD) band or a frequency division duplexing (FDD). In this case, the downlink resource may be separated from the uplink resource, in the frequency domain, by a guard band. 
     As indicated above,  FIG.  4    is provided as an example. Other examples may differ from what is described with respect to  FIG.  4   . 
     A bandwidth or carrier that a base station and a UE (which may also be referred to as a “mobile station” or a “first network node”) use to communicate may be divided into a plurality of bandwidth parts (BWPs). Each BWP may support communication for a service on the carrier. For example, a first BWP may support enhanced mobile broadband (eMBB) service and a second BWP may support ultra-reliable low-latency communication (URLLC) service. A BWP is a contiguous (or in some proposed cases, non-contiguous) set of physical resource blocks (PRBs) that have a common configuration for supporting the service assigned to the BWP. A BWP may be defined in terms of a central frequency or resource element and a bandwidth of the BWP. 
     Some communications systems may support flexible BWP configuration. In flexible BWP configuration, different BWPs may be configured with different TDD patterns to enable FD communication between a UE and a base station. For example, a first BWP may be configured with a first TDD pattern and a second BWP may be configured with a second TDD pattern, which may enable support for IBFD or SBFD operation. In flexible BWP operation with FD operation, using a central frequency and a bandwidth to define a BWP, as described above, results in downlink resources and uplink resources having the same central frequency and bandwidth. However, in some cases, a level of traffic for a downlink may be different than a level of traffic for an uplink. As a result, defining a BWP for FD operation with the same quantity of downlink resources and uplink resources may result in insufficient resources on a downlink or uplink or result in excess resources on a downlink or uplink. Configuring insufficient resources or excess resources is an inefficient allocation of network resources, which may result in poor network performance on the BWP (when insufficient network resources are allocated) or on other BWPs (when excess network resources are allocated, and insufficient network resources remain available for other BWPs). 
     Some aspects described herein enable flexible BWP-specific configuration. For example, a base station may configure a UE (e.g., a network node) with a frequency offset value to enable the UE to derive differing resource allocations for an uplink and a downlink on a flexible BWP. In other words, the base station may identify the central frequency and the bandwidth, which may be applicable to one of a downlink or an uplink, and may identify an offset, which may be applicable to the other of the downlink or the uplink. The UE may use the offset to shift the central frequency and expand or contract the bandwidth for the other of the downlink or the uplink. In this way, the base station and the UE can achieve differentiated uplink resource allocations and downlink resource allocations, thereby avoiding an insufficient or excessive allocation of resources for a BWP. By avoiding the insufficient or excessive allocation of resources, the base station and the UE improve network performance. 
       FIG.  5    is a diagram illustrating an example  500  associated with flexible bandwidth part frequency offset configuration, in accordance with the present disclosure. As shown in  FIG.  5   , example  500  includes communication between a base station  110  and a UE  120 . In some aspects, base station  110  and UE  120  may be included in a wireless network, such as wireless network  100 . Base station  110  and UE  120  may communicate via a wireless access link, which may include an uplink and a downlink. 
     As further shown in  FIG.  5   , and by reference number  505 , UE  120  may receive bandwidth part configuration signaling from base station  110 . For example, UE  120  may receive information identifying a central frequency for a bandwidth part, a bandwidth for the bandwidth part, or a configured offset for the bandwidth part, among other examples. UE  120  may determine a configuration for an uplink on the bandwidth part and for a downlink on the bandwidth part, and UE  120  may communicate with base station  110  on the uplink and the downlink in accordance with the configuration, as shown by reference number  510 . In some aspects, UE  120  may receive information configuring a switching time associated with the bandwidth part. For example, base station  110  may determine a switching time between central frequencies for UE  120  based at least in part on a capability of UE  120 . In this case, a gap may be configured between downlink resources and uplink resources that are offset from the downlink resources in terms of central frequency, thereby enabling UE  120  to switch between a first central frequency for the downlink resources and a second central frequency for the uplink resources. For example, UE  120  may receive signaling indicating an amount of time that is to elapse between downlink resources and the uplink resources that are offset from the downlink resources. In this case, UE  120  may use the indicated amount of time for switching between monitoring a central frequency of the downlink and monitoring a central frequency of the uplink. In some aspects, the size of the gap may be based at least in part on a UE capability (e.g., how quickly the UE  120  is capable of switching between monitoring different frequencies) and/or a size of the configured offset (e.g., how large a frequency spread the UE  120  is to traverse to switch between monitoring different frequencies). 
     In some aspects, UE  120  may use the configured offset to identify a set of resources for an uplink or a downlink. For example, as shown by reference number  515 , UE  120  may identify different frequency resources for a downlink and an uplink. In this case, based at least in part on the configured offset, the uplink is offset, in frequency resources, from the downlink by a particular amount of resource elements (REs) or resource blocks (RBs). For example, the particular amount of REs or RBs may define the configured offset (e.g., specify an amount of frequency by which the configured offset establishes the different frequency resources for the downlink and the uplink). Additionally, or alternatively, the uplink may be offset from the downlink by a particular frequency range value. For example, the configured offset may be defined as a particular size frequency range, and the uplink may be offset from the downlink by the particular size frequency range. In some aspects, UE  120  may use an indicated central frequency for the downlink and apply the configured offset to identify another central frequency for the uplink (relative to the downlink). 
     Alternatively, UE  120  may use the indicated central frequency for the uplink and apply the configured offset to identify another central frequency for the downlink (relative to the uplink). In other words, although some aspects are described herein in terms of an uplink relative to a downlink, it should be understood that aspects described herein may apply to a downlink relative to an uplink, a first sidelink direction relative to a second sidelink direction, or any other type of full-duplex or other bidirectional communications. For example, the configured offset may be a particular quantity of REs that the downlink is to be offset from the uplink or that a first sidelink is to be offset from a second sidelink, among other examples. 
     In some aspects, UE  120  may receive a first configured offset for an uplink relative to a defined central frequency and a second configured offset for a downlink relative to the defined central frequency. In this case, UE  120  may receive first signaling (e.g., radio resource control (RRC) signaling) identifying the defined central frequency and second signaling (e.g., medium access control (MAC) control element (CE) or downlink control information (DCI) signaling) identifying one or more configured offsets. 
     In some aspects, UE  120  may use a plurality of configured offset values to identify a plurality of sets of resources for an uplink or a downlink. For example, as shown by reference number  520 , UE  120  may determine a first frequency offset (relative to a downlink) for a first subset of uplink resources (e.g., with a first periodicity) and a second frequency offset (relative to a downlink) for a second subset of uplink resources (e.g., with a second periodicity). As a particular example, UE  120  may receive two offset indicators identifying a first offset for 100 RBs frequency offset from the central frequency and a second offset for 150 RBs frequency offset from the central frequency. In this case, UE  120  may use the first offset for two slots and the second offset for three slots. In some aspects, UE  120  may determine the periodicity based at least in part on an explicit indicator (e.g., of the 2 slot periodicity for the first offset and the 3 slot periodicity for the second offset), an additive indicator (e.g., indicating 1 extra slot for the periodicity for the second offset), or a multiplicative indicator (e.g., indicating that the second offset has a periodicity 1.5 times that of the first offset or that the first offset has a periodicity of ⅔ that of the downlink bandwidth), among other examples. 
     In some aspects, UE  120  may receive an offset value identifying an offset in a size of a bandwidth between a downlink and an uplink. For example, as shown by reference number  525 , UE  120  may receive signaling identifying a first size bandwidth for a downlink and an offset identify a second size bandwidth (relative to the first size bandwidth) for an uplink. In this case, the first size bandwidth and the second size bandwidth may be based at least in part on a bandwidth scale, such as an additive scale (e.g., where the offset identifies a quantity of fewer or additional RBs or resource block groups (RBGs) for the uplink relative to the downlink) or a multiplicative scale (e.g., where the offset identifies a multiple of a bandwidth for the downlink that the UE  120  is to use for the uplink, such as an integer multiple for a larger bandwidth or a fractional multiple for a smaller bandwidth), among other examples. 
     In some aspects, UE  120  may identify a flexible resource (e.g., that may be used for downlink or uplink) for communication on the BWP. For example, UE  120  may use the offset value to identify a flexible resource relative to a reference central frequency and bandwidth. In this case, UE  120  may determine that resources within a bandwidth defined for the downlink or uplink are single directional resource and that other resources not within the bandwidth defined for the downlink or uplink are a guard band or a flexible resource, as shown by reference number  530 . 
     As indicated above,  FIG.  5    is provided as an example. Other examples may differ from what is described with respect to  FIG.  5   .
