TECHNICAL FIELD

[0003] Aspects of the disclosure relate generally to wireless communication, and to techniques and apparatuses for uplink power control for full duplex communication. BACKGROUND

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 (3 GPP).

[0005] A wireless network can include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE can communicate with a BS via the downlink and uplink. “Downlink” (or “forward link”) refers to the communication from the BS to the UE, and “uplink” (or “reverse link”) refers to the communication from the UE to the BS. As will be described in more detail

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocol that enables different wireless devices to communicate on the same frequency. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3 GPP. 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 (DL), using CP- OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE, NR, and other radio access technologies. SUMMARY

[0007] In some aspects, a method of wireless communication, performed by a user equipment (UE), can include receiving a downlink control information (DCI) scheduling an uplink communication in an uplink frequency band; and transmitting the uplink communication at an uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE.

[0011] In some aspects, a non-transitory computer-readable medium can store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, can cause the one or more processors to receive DCI scheduling an uplink communication in an uplink frequency band; and transmit the uplink communication at an uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE.

[0012] In some aspects, a non-transitory computer-readable medium can store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a base station, can cause the one or more processors to transmit, to a UE, DCI scheduling an uplink communication in an uplink frequency band; and receive, from the UE, the uplink communication at an uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE.

[0013] In some aspects, an apparatus for wireless communication can include means for receiving DCI scheduling an uplink communication in an uplink frequency band; and means for transmitting the uplink communication at an uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE.

[0014] In some aspects, an apparatus for wireless communication can include means for transmitting, to a UE, DCI scheduling an uplink communication in an uplink frequency band; and means for receiving, from the UE, the uplink communication at an uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE.

[0026] Various aspects of the disclosure are more fully described herein with reference to the figures. The disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using, in addition to or in place of the aspects set forth herein, other structures, functionalities, or structures and

[0027] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can 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.

[0028] ​​It should be noted that while aspects can be described herein using terminology commonly associated with a 5G or 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).

[0029] FIG. 1 FIG. 1 is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 can be or include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 can include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and can also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), or the like. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and / or a subsystem of a BS that serves the coverage area, depending on the context in which the term is used.

[0030] BSs can be referred to as macro BS, small cell, femto cell, and / or other types of BSs. A macro cell can cover a relatively large geographic area (e.g., 5-10 miles in radius) and can allow unrestricted access by UEs with service subscriptions. A small cell can cover a relatively small geographic area and can allow restricted access by UEs having service subscriptions with the small cell. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs having service subscriptions with the femto cell. A BS for a macro cell can be referred to as a macro BS. A BS for a small cell can be referred to as a small cell BS. A BS for a femto cell can be referred to as a femto BS or a home BS. In the example shown, a BS 110a can be a macro BS for a macro cell 102a, a BS 110b can be a small cell BS for a small cell 102b, and BSs 110c can be femto BS for femto cells 102c. A BS can support one or multiple (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “node B,” “5G NB,” and “cell” can be used interchangeably herein. FIG. 1 In the example shown, the BSs 110a can be macro BSs for macro cells 102a and the BSs 110b can be small cell BSs for small cells 102b. A BS can support one or multiple (e.g., three) cells. The term “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “node B,” “5G NB,” and “cell” can be used interchangeably herein.

[0031] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move based on the location of a mobile BS. In some aspects, BSs can be interconnected to one another and / or to one or more other BSs or network nodes (not shown) in wireless network 100 using any suitable transport network, including a direct physical connection, or virtual network.

[0032] Wireless communication network 100 can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. FIG. 1 In the example shown in Figure 1, relay BS 1 lOd can communicate with macro BS 110a and a UE 120d in order to facilitate communications between the BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a relay, or the like.

[0033] Wireless network 100 can be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs can have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs can have relatively lower transmit power levels (e.g., 0.1 to 2 watts).

[0034] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can be in communication with the BSs via a backhaul. The BSs can also communicate with one another directly or indirectly via a wireless or wireline backhaul.

[0035] The UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. A UE can 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 or equipment, a biometric sensor / device, a wearable device such as a smart watch, smart clothing, smart glasses, a smart wrist band, a smart jewel (e.g., a smart ring, a smart bracelet, etc.), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0036] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, e.g., robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Internet-of-Things (IoT) devices, and / or can be implemented as NB-IoT (narrowband internet of things) devices. Some UEs can be considered Customer Premises Equipment (CPE). The UE 120 can be included inside a housing that houses components of the UE 120, such as processor components and / or memory components. In some aspects, the processor components and the memory components can be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0037] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, etc. A frequency can also be referred to as a carrier, a frequency channel, etc. Each frequency can 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 can be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for their communications). For example, UEs 120 can communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which can include car-to-car (V2V) or car-to-infrastructure (V2I) protocols), and / or mesh networking. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0039] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided based on frequency or wavelength into various classes, bands, channels, and / or the like. For example, devices of wireless network 100 can communicate using an operating band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz and / or can communicate using an operating band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band 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. Thus, unless specifically stated otherwise, the term “sub-6 GHz” or the like, if used herein, can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, the term “millimeter wave” or the like, if used herein, can broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and, as such, the techniques described herein can be applicable to those modified frequency ranges.

[0040] As described above, FIG. 1 Provided by way of example. Other examples can differ from those described FIG. 1 without departing from the spirit of the disclosure.

[0041] FIG. 2is 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. Base station 110 can be equipped with T antennas 234a through 234t, and UE 120 can be equipped with R antennas 252a through 252r, where in general T > 1 and R > 1.

[0042] At base station 110, a transmit processor 220 can receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 can also 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. Transmit processor 220 can also 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) and a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 can process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t can be transmitted via T antennas 234a through 234t, respectively.

[0043] At the UE 120, the antennas 252a-252r can receive the downlink signals from the base station 110 and / or other base stations and can provide received signals to the demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. A channel processor can determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some aspects, one or more components of UE 120 can be included in a housing 284.

[0044] The network controller 130 can include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 can include, for example, one or more devices in a core network. The network controller 130 can communicate with the base station 110 via the communication unit 294.

[0045] In other examples, antennas (e.g., antennas 234a-234t and / or antennas 252a-252r) can include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. An antenna panel, antenna group, antenna element set, and / or antenna array can include one or more antenna elements. An antenna panel, antenna group, antenna element set, and / or antenna array can include a set of co-planar antenna elements and / or a set of non-co-planar antenna elements. An antenna panel, antenna group, antenna element set, and / or antenna array can include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, antenna element set, and / or antenna array can include one or more antenna elements that are coupled to one or more transmit and / or receive components, such as FIG. 2 one or more components of the UE 120.

[0046] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 254) of the UE 120 can be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver can include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the methods described herein (for example, with reference to FIG. 6A , FIG. 6B and FIGS. 7-11 .

[0047] At base station 110, the uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and channel information transmitted by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and to controller / processor 240 for control information received from UE 120. Base station 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 can include scheduler 246 to schedule UEs 120 for downlink and / or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 232) of the base station 110 can be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver can include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform any of the methods described herein (for example, with reference to FIG. 6A , FIG. 6B and FIGS. 7-11 .

[0048] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or FIG. 2 Any other component(s) in the system may perform one or more techniques associated with uplink power control for full-duplex communication, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or FIG. 2 Any other component(s) in it can perform or direct, for example FIG. 8 The process 800 FIG. 9 The process 900 FIG. 10 Process 1000 FIG. 11 The operation of process 1100 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or 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, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), the one or more instructions may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example... FIG. 8 The process 800 FIG. 9 The process 900 FIG. 10 Process 1000 FIG. 11 The operation of process 1100 and / or other processes as described herein. In some aspects, and in other examples, execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions.

[0049] In some aspects, UE 120 may include components for receiving (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282 and / or the like) a DCI that schedules uplink communication in the uplink band, components for transmitting (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, memory 282 and / or the like) uplink communication at an uplink frequency within the uplink band with power varying in the uplink band at least in part based on the position of the uplink frequency relative to the downlink band associated with UE 120, and / or similar components. In some aspects, such components may include combinations of FIG. 2One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0050] In some aspects, base station 110 can include means for transmitting (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, memory 242, and / or the like) DCI to a UE scheduling uplink communications in an uplink frequency band, means for receiving (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, and / or the like) uplink communications from the UE at an uplink frequency within the uplink frequency band at a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE, and / or the like. In some aspects, such means can include one or more components of UE 120 (e.g., controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.) described above. FIG. 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0051] Although FIG. 2 The blocks in may be illustrated as distinct components, the functionality described above in relation to the blocks can be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described in relation to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.

[0052] As described above, FIG. 2 are provided by way of example. Other examples can differ from what is described in connection with FIG. 2 what is described in connection with

[0053] FIGS. 3A-3C are diagrams illustrating examples 300, 310, 320 of full-duplex (FD) communication, in accordance with the present disclosure. FD communication can include simultaneous uplink and downlink communication. For example, the uplink and downlink communication can at least partially overlap in time.

[0054] FIG. 3AExample 300 includes UE1 302 and two base stations (e.g., TRPs) 304-1, 304-2, where UE1 302 is transmitting UL transmissions to base station 304-1 and receiving DL transmissions from base station 304-2. In FIG. 3A Example 300, FD is enabled for UE1 302, and FD is not enabled for base stations 304-1, 304-2 (e.g., half duplex (HD) communications are enabled for base stations 304-1, 304-2). Further, as shown by reference 306, the UL transmissions to base station 304-1 can cause self-interference with the DL transmissions from base station 304-2. This can be caused by a variety of factors, such as transmit power for the UL transmissions (as compared to the DL transmissions), radio frequency bleeding, and / or the like.

[0055] FIG. 3B Example 310 includes two UEs (UE1 302-1 and UE2 302-2) and a base station 304, where UE1 302-1 is receiving DL transmissions from base station 304, and UE2 302-2 is transmitting UL transmissions to base station 304. In FIG. 3B Example 310, FD is enabled for base station 304, and FD is not enabled for UE1 302-1 and UE2 302-2 (e.g., HD communications are enabled for UE1 302-1 and UE2 302-2). Further, as shown by reference 308, the DL transmissions from base station 304 to UE1 302-1 can cause self-interference with the UL transmissions from UE2 302-2 to base station 304.

[0056] FIG. 3C Example 320 includes UE1 302 and base station 304, where UE1 302 is receiving DL transmissions from base station 304, and UE1 302 is transmitting UL transmissions to base station 304. In FIG. 3C Example 320, FD is enabled for both UE1 302 and base station 304. Further, as shown by reference 310, the UL transmissions to base station 304 can cause self-interference with the DL transmissions from base station 304.

[0057] As described above, FIGS. 3A-3C are provided as one or more examples. Other examples can differ from what is described in connection with FIGS. 3A-3C the description.

[0058] FIGS. 4A-4C is a diagram illustrating various duplex modes in a radio access network, in accordance with the present disclosure. FIG. 4AA time division duplex (TDD) communication pattern between a UE and a base station is depicted. In TDD, only one endpoint (e.g., one of a UE or a base station) can transmit information to the other endpoint (e.g., the other of the UE or the base station) at a time. For example, in TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, at some times, the channel is dedicated to transmissions in one direction, while at other times, the channel is dedicated to transmissions in the other direction. In some cases, the direction can change rapidly, e.g., several times per slot. Thus, as FIG. 4A shown, DL communications 402 are separated in time from UL communications 404.

[0059] FIG. 4B A frequency division duplex (FDD) communication pattern between a UE and a base station is depicted. In FDD, both endpoints can communicate with each other simultaneously on different frequencies (e.g., different frequency bands, sets of subcarriers, resource blocks, and / or the like). In FDD mode, as FIG. 4B shown, transmissions in different directions operate on different carrier frequencies. Thus, as FIG. 4B shown, DL communications 402 are separated in frequency from UL communications 404, which is shown as a guard band. In some cases, FDD can be referred to as full duplex because a wireless communication device can be able to transmit and receive simultaneously, with the transmission using a first frequency and the reception using a second frequency. Because the simultaneous transmission and reception by a device in FDD uses different frequencies, this full duplex mode can be referred to as sub-band FDD (or flexible duplexing).

[0060] FIG. 4C A true FD communication pattern between a UE and a base station is described. As FIG. 4C shown, in true FD mode, transmissions in different directions operate on the same carrier frequency or within overlapping bandwidths. In FIG. 4C the example shown, DL communications 402 overlap (e.g., partially or completely) UL communications 404 in time and frequency. Thus, when operating in true FD mode, a UE and a base station are configured for simultaneous transmission and reception within an overlapping bandwidth. That is, the simultaneous transmission and reception by a device in this mode can use the same frequency. Thus, this FD mode can be referred to as in-band FD.

[0061] As described above, FIGS. 4A-4C provided by way of example. Other examples can differ from what is described in connection with FIGS. 4A-4C what is described.

[0062] FIG. 5 is a diagram illustrating an example of an FDD configuration in accordance with the present disclosure. FIG. 5An example of a time interval 510 (e.g., a slot, a group of slots, a subframe, a subslot, a mini-slot, and / or the like) is shown. The time interval can include an uplink frequency region, a downlink frequency region, or both an uplink frequency region and a downlink frequency region. Each time interval can be associated with a control region (shown as the darker shaded portion of the time interval) and / or a data region (shown as DL data of the downlink frequency region or a physical uplink shared channel (PUSCH) of the uplink frequency region). The uplink frequency region is shown using tighter dashed fill than the downlink frequency region.

[0063] An FDD configuration can indicate one or more downlink frequency regions and one or more uplink frequency regions. For example, the FDD configuration can partition an unpaired frequency band (e.g., one or more component carriers of an unpaired frequency band) into uplink frequency regions, downlink frequency regions, and / or other regions (e.g., guard bands and / or the like). The uplink frequency regions and the downlink frequency regions can be equal in bandwidth or unequal in bandwidth. In some aspects, the FDD configuration can identify a bandwidth part (BWP) configuration corresponding to the uplink frequency regions and the downlink frequency regions. For example, a respective BWP can be configured for each uplink frequency region and each downlink frequency region. FDD can increase throughput and improve spectral efficiency, and can enable the use of always-on uplink (e.g., for ultra-reliable low-latency communication (URLLC) control channels).

[0064] As FIG. 5 Further shown, the base station (or UE) can include multiple antenna panels (e.g., antenna port groups), shown as panel 1 and panel 2. The multiple antenna panels can enable simultaneous transmit (Tx) and receive (Rx) operations. Moreover, the multiple antenna panels can provide improved isolation for the simultaneous transmit and receive operations.

[0065] In some cases, as FIG. 5 shown, the base station (or UE) can switch between FD and HD modes on a slot-to-slot basis. As an example, in an HD downlink time interval (e.g., a slot), the base station can transmit downlink transmissions using panel 1 and panel 2. In an FD time interval, the base station can transmit downlink transmissions using panel 1 and receive uplink transmissions using panel 2. In an HD uplink time interval, the base station can receive uplink transmissions using panel 1 and panel 2.

[0066] As shown by reference number 520, in the FD mode, downlink communications (e.g., on panel 1) can use the edges of the frequency band, and uplink communications (e.g., on panel 2) can use the middle region of the frequency band (e.g., between the edges). However, as shown, frequency bleed over of the uplink communications can cause interference to the downlink communications (which can be a problem for the UE), and frequency bleed over of the downlink communications can cause interference to the uplink communications (which can be a problem for the base station).

[0067] The base station (or UE) can perform various techniques to root out or cancel the self-interference, e.g., antenna isolation (transmitting or receiving using physically separated antennas, as described above), analog interference cancellation, digital interference cancellation, massive-MIMO (M-MIMO) based beamforming nulling for achieving clutter reflection, and sub-band FD for achieving isolation based at least in part on adjacent channel leakage ratio (ACLR), and / or the like. In sub-band FD, the downlink and uplink are in different parts of the frequency band or component carrier, as described above. A guard band (GB) can be set between the uplink and downlink. A receive weighting overlap and add (WOLA) operation can reduce ACLR leakage to the uplink signal. An analog low pass filter can improve the analog-to-digital converter (ADC) dynamic range.

[0068] As described above, FIG. 5 Provided by way of example. Other examples can differ from what is described FIG. 5 The content provided is provided for example.

[0069] As described above, self-interference occurs when one signal is transmitted and another signal is received in overlapping time resources (e.g., FD resources). In some cases, reducing the transmit power can reduce the strength of the self-interference. For example, a base station can reduce downlink transmit power (e.g., perform downlink power control) to reduce self-interference, and a UE can reduce uplink transmit power (e.g., perform uplink power control) to reduce self-interference. The UE can perform uplink power control for uplink communications, e.g., PUSCH communications, physical uplink control channel (PUCCH) communications, sounding reference signal (SRS), or random access channel (RACH) communications. For example, the UE can use Equation 1 for PUSCH power control (per 3GPP Technical Specification (TS) 38.213):

[0070]

[0071] where P O_PUSCH (j) is the target power, a(j) is a path loss adjustment factor, and D TF denotes the MCS and code rate used for the uplink transmission.

[0072] In current wireless networks, uplink power control (e.g., to reduce self- interference) reduces the uplink transmit power across an entire uplink frequency band used for uplink transmissions. That is, a single uplink transmit power is used across the entire uplink frequency band for uplink transmissions. However, reducing the uplink transmit power across the entire uplink frequency band can impair the performance of uplink transmissions by weakening the strength of the uplink transmissions.

[0073] Some techniques and apparatuses described herein provide improved uplink power control for uplink transmissions associated with FD communications. In some aspects, a UE can transmit uplink communications with power that varies across an uplink frequency band. For example, the power can vary based at least in part on a location of an uplink frequency within the uplink frequency band relative to a downlink frequency band used for FD communications. As an example, the UE can transmit uplink communications with less power in sub-bands of the uplink frequency band that are closer to the downlink frequency band and with more power in sub-bands of the uplink frequency band that are farther from the downlink frequency band. In this way, the signal strength of the uplink communications can be improved (e.g., relative to transmitting the uplink communications with a single transmit power), thereby improving the performance of the uplink communications. Also, self-interference with downlink communications in the downlink frequency band can be reduced, thereby improving the performance of the downlink communications.

[0074] FIG. 6A FIG. 6 is a diagram illustrating an example 600 associated with uplink power control for FD communications, in accordance with the present disclosure. As shown, example 600 includes a base station 110 and a UE 120. In some aspects, UE 120 can operate in an FD communication mode (e.g., UE 120 can be an FD UE). For example, UE 120 can simultaneously transmit uplink communications to base station 110 and receive downlink communications from base station 110. As another example, UE 120 can simultaneously transmit uplink communications to base station 110 (e.g., a first TRP) and receive downlink communications from another base station 110 (e.g., a second TRP). FIG. 6A

[0075] ​As shown by reference number 605, the base station 110 can transmit (e.g., via radio resource control (RRC) signaling) and the UE 120 can receive one or more power offset configurations and / or power adjustment configurations. The power offset configuration can include information (e.g., a table, a mapping, and / or the like) that identifies one or more sets of power offset values for a plurality of subbands (e.g., an uplink frequency band of an FD resource, a component carrier, a bandwidth part, and / or the like) of an uplink frequency band. For example, a set of power offset values can include respective power offset values (e.g., 0, -2, +3, and / or the like) for a plurality of subbands. For example, a first power offset value of the set can be associated with a first subband, a second power offset value of the set can be associated with a second subband, and so on (e.g., each resource bandwidth is configured with a power offset). In some aspects, a power offset value for a subband can be negative infinity to prevent transmission on the subband (e.g., to penetrate a transmission in the subband). Different sets of power offset values can indicate different combinations of power offset values, thereby providing different variations for uplink transmit power on the uplink frequency band.

[0076] In some aspects, the power offset configuration or another configuration (e.g., another RRC configuration) can configure a plurality of subbands. For example, each subband of the plurality of subbands can be configured to a particular size (e.g., a number of resource elements (REs), a number of resource blocks (RBs), a number of RB groups (RBGs), and / or the like), and the plurality of subbands can include subbands of different sizes and / or include subbands of the same size. Accordingly, each power offset value of a set of power offset values can be associated with a particular subband size. For example, a first power offset value can be associated with a first subband size (e.g., a number of REs, RBs, RBGs, and / or the like), a second power offset value can be associated with a second subband size, and so on. Different sets of power offset values can indicate different combinations of subband sizes, thereby providing different variations for uplink transmit power on the uplink frequency band.

[0077] The power adjustment configuration can include information (e.g., a table, a mapping, and / or the like) that identifies one or more sets of power adjustment values for a plurality of symbols (e.g., symbol indices). For example, a set of power adjustment values can include respective power adjustment values (e.g., 1, -0.1, +0.2, and / or the like) for a plurality of symbols. As an example, a first power adjustment value of the set can be associated with a first symbol (e.g., symbol index), a second power adjustment value of the set can be associated with a second symbol, and so on. The plurality of symbols can be associated with a slot (e.g., 14 symbols) or another time interval. Different sets of power adjustment values can indicate different combinations of power adjustment values.

[0078] As shown by reference number 610, the base station 110 can transmit, and the UE 120 can receive, downlink control information (DCI). The DCI can indicate an uplink grant for the UE 120. For example, the DCI can schedule an uplink communication for the UE 120 at an uplink frequency within an uplink band (e.g., an uplink band of the FD resources). The DCI can schedule the uplink communication in resources that overlap in time with a downlink communication that is to be received by the UE 120 in one or more downlink bands (e.g., one or more downlink bands of the FD resources). That is, the UE 120 can be scheduled to transmit an uplink communication and receive a downlink communication in the same or overlapping time resources (e.g., in the FD resources). Further, the DCI can schedule the uplink communication in resources that overlap in frequency with the downlink communication (e.g., in-band FD), or in resources that do not overlap in frequency with the downlink communication (e.g., sub-band FDD).

[0079] In some aspects, the DCI can indicate a set of power offset values and / or a set of power adjustment values that the UE 120 is to use for the uplink communication. That is, the DCI can activate a particular set of power offset values from one or more sets of power offset values configured for the UE 120, and / or activate a particular set of power adjustment values from one or more sets of power adjustment values configured for the UE 120. In some aspects, the base station 110 can indicate (e.g., activate) the set of power offset values and / or the set of power adjustment values that the UE 120 is to use for the uplink communication via medium access control (MAC) control element (MAC-CE) and / or RRC signaling. In some aspects, the base station 110 can determine the set of power offset values and / or the set of power adjustment values that the UE 120 is to use for the uplink communication based at least in part on a location of the uplink frequency relative to the downlink band(s), as described below.

[0080] As shown by reference number 615, the UE 120 can determine a set of power offset values and / or a set of power adjustment values that the UE 120 is to use for the uplink communication. For example, the UE 120 can determine the set of power offset values and / or the set of power adjustment values from an indication (e.g., activation) provided by the base station 110 (e.g., in the DCI), as described above.

[0081] Additionally or alternatively, the UE 120 can determine the set of power offset values and / or the set of power adjustment values based at least in part on a location of the uplink frequency relative to the downlink frequency band(s). In some aspects, the UE 120 can determine the set of power offset values and / or the set of power adjustment values based at least in part on a size of a frequency separation between the uplink frequency and the downlink frequency band(s). As an example, the UE 120 can select a first set of power offset values (e.g., associated with a first power attenuation) if the size of the frequency separation satisfies a first threshold, and can select a second set of power offset values (e.g., associated with a second power attenuation) if the size of the frequency separation satisfies a second threshold (or does not satisfy the first threshold).

[0082] For example, the UE 120 can select a set of power offset values that includes relatively small power offset values for subbands associated with the edge(s) of the uplink frequency band (e.g., a first and / or last power offset value of the set, a first two and / or last two power offset values of the set, and / or the like) if the size of the frequency separation satisfies a third threshold (e.g., the size of the frequency separation is greater than a configured guard band size). As another example, the UE 120 can select a set of power offset values that includes relatively large power offset values for subbands associated with the edge(s) of the uplink frequency band if the size of the guard band (e.g., between the uplink frequency band and the downlink frequency band(s)) satisfies another threshold (e.g., the size of the guard band is less than another threshold). In some aspects, the uplink communication can not overlap in time with a downlink communication that the UE 120 is to receive. In this case, the UE 120 can select a set of power offset values that does not include non-zero power offset values for the subbands (e.g., the set of power offset values can all be zero). Additional or alternative rules can also be used to determine the set of power offset values to use for the uplink communication in addition to or instead of the examples described above.

[0083] In this way, the set of power offset values is selected such that if the uplink frequency and the downlink frequency band(s) are closer, the subbands associated with the edge(s) of the uplink frequency band and thus closest to the downlink frequency band(s) can be associated with a relatively larger power attenuation (or a relatively small power increase), and if the uplink frequency and the downlink frequency band(s) are farther apart, the subbands can be associated with a relatively smaller power attenuation (or a relatively larger power increase). For example, the UE 120 can use lower power for subbands that are closer to the downlink frequency band and higher power for subbands that are farther from the downlink frequency band.

[0084] As shown by reference number 620, the UE 120 can determine an uplink transmit power for the uplink communication. In cases where the UE 120 is to use a set of power adjustment values, the UE 120 can determine the uplink transmit power for the uplink communication according to Equation 1, described above. In such cases, the UE 120 can apply the set of power adjustment values to the determined uplink transmit power. For example, in a first symbol, the UE 120 can apply a first power adjustment value of the set to the determined uplink transmit power, in a second symbol, the UE 120 can apply a second power adjustment value of the set to the determined uplink transmit power, and so on.

[0085] In cases where the UE 120 is to apply a set of power offset values, the UE 120 can determine respective uplink transmit powers for a plurality of sub-bands of the uplink frequency band based at least in part on the set of power offset values (e.g., by adding a power offset value for a sub-band to an uplink transmit power for the sub-band, or subtracting the power offset value from the uplink transmit power). For example, the UE 120 can determine the respective uplink transmit powers for the plurality of sub-bands according to Equation 2.

[0086]

[0087]

[0088] The uplink transmit power for the uplink communication by the UE 120 can be based at least in part on the respective uplink transmit powers determined for the plurality of sub-bands. That is, the uplink transmit power for the uplink communication by the UE 120 can vary (e.g., fluctuate) across the uplink frequency band based at least in part on the respective uplink transmit powers determined for the plurality of sub-bands.

[0089] As shown by reference number 625, at an uplink frequency in the uplink frequency band, the UE 120 can transmit and the base station 110 (or another base station 110) can receive an uplink communication. The UE 120 can transmit the uplink communication using an uplink transmit power determined by the UE 120. Thus, the uplink transmit power used by the UE 120 can vary across the uplink frequency band (e.g., as the uplink transmit power can be based at least in part on a plurality of subband uplink transmit powers according to a set of power offset values, where the uplink frequency is within or corresponds to one of the plurality of subbands associated with one of the subband uplink transmit powers). Moreover, the UE 120 can receive a downlink communication (e.g., from the base station 110 or another base station 110) at the same time as transmitting the uplink communication. In this way, the UE 120 can use greater transmit power for the uplink communication and can reduce self-interference with the downlink communication, thereby improving performance of the uplink communication and the downlink communication.

[0090] In some aspects, the UE 120 can transmit the uplink communication using different power control parameters, such as using an uplink power control parameter for each subband, as described below in connection with FIG. 6B Each subband uplink power control parameter provides more control and greater flexibility for reduction of self-interference while also protecting the uplink communication.

[0091] As described above, FIG. 6A are provided by way of example. Other examples can differ from what is described in connection with FIG. 6A what is described in connection with

[0092] FIG. 6B is a diagram illustrating an example 650 associated with uplink power control for FD communications, in accordance with the present disclosure. As shown in FIG. 6B example 650 includes a base station 110 and a UE 120, as described above in connection with FIG. 6A examples.

[0093] As shown by 655, the base station 110 can configure power control information for one or more subbands of an uplink transmission (e.g., the uplink communication described above in connection with FIG. 6A The base station 110 can configure the power control information for the one or more subbands of the uplink transmission based at least in part on the subband full-duplex communication. For example, as shown by 660, the base station 110 can transmit the power control information to the UE 120. The UE 120 can receive the power control information from the base station 110. In some aspects, the power control information includes at least one of a maximum power, a minimum power, a band separation from a downlink transmission, or a band corresponding to a half-duplex transmission.

[0094] In some aspects, the power control configuration value can include at least one of subband information for power control or power control parameters for at least one subband. In some aspects, the UE 120 can receive a configuration of one or more power control parameters for a first subband of the at least one subband for an uplink transmission. The power control configuration of the power control parameters for the uplink transmission is received from the base station 110 via RRC or DCI signaling. In some aspects, the one or more power control parameters for the first subband can include at least one of a maximum power, a minimum power, a band separation from a band of a downlink transmission, or a band corresponding to a half duplex transmission.

[0095] In some aspects, as shown at 665, the UE 120 can determine the power control parameters. The UE 120 can determine the power control parameters for one or more additional subbands for the uplink transmission. The UE 120 can determine the power control parameters for the one or more additional subbands for the uplink transmission based at least in part on at least two of a frequency allocation of the first subband, a bandwidth of the first subband, or a beam configuration of the UE 120.

[0096] At 670, the UE 120 can apply the first set of one or more power control parameters. The UE 120 can apply the first set of one or more power control parameters for the first subband of the uplink transmission.

[0097] At 675, the UE 120 can apply the second set of one or more power control parameters. The UE 120 can apply the second set of one or more power control parameters for the second subband of the uplink transmission. In some aspects, the UE 120 can apply the first set of one or more power control parameters for the first subband and the second set of one or more power control parameters for the second subband during full duplex symbols and half duplex symbols. In some aspects, the first power control parameters and the second power control parameters include a target power, a path loss adjustment factor, an offset value, or a downlink MCS term. In some aspects, at least one of the first set of one or more power control parameters or the second set of one or more power control parameters is determined by the UE 120. For example, via the base station 110, the network can signal the uplink power control parameters for the one or more subbands such that the UE 120 can derive the uplink power control parameters for each of the one or more subbands based at least in part on a frequency allocation and a corresponding bandwidth of the subband. In some aspects, at least one of the first set of one or more power control parameters or the second set of one or more power control parameters is received from the network. For example, via the base station 110, the network can configure the UE 120 with the uplink power control parameters for each of the one or more subbands via RRC or scheduling DCI.

[0098] At 680, the UE 120 can transmit the uplink transmission. The UE 120 can transmit the uplink transmission over at least the first sub-band based at least in part on the first set of one or more power control parameters and over at least the second sub-band based at least in part on the second set of one or more power control parameters. In some aspects, at least one of the first set of one or more power control parameters or the second set of one or more power control parameters can be defined for a sounding reference signal (SRS) resource indicator (SRI) or for a URLLC or non-URLLC mode. The uplink transmission can include at least one of a PUSCH, a PUCCH, an SRS, or a RACH. At least one of the first set of one or more power control parameters or the second set of one or more power control parameters can be associated with at least one of the PUSCH, the PUCCH, the SRS, or the RACH for full-duplex operation. In some aspects, a set of power control parameters can be configured for half-duplex communication for at least one of the PUSCH, the PUCCH, the SRS, or the RACH. In some aspects, a power control parameter can be configured for full-duplex communication. In some aspects, the UE 120 can apply full-duplex sub-band uplink power control, for example, for uplink transmissions across both full-duplex symbols and half-duplex symbols, in an effort to reduce or avoid phase discontinuities.

[0099] As described above, FIG. 6B are provided by way of example. Other examples can differ from FIG. 6B what is described in connection with the following description.

[0100] FIG. 7 FIG. 7 is a diagram illustrating an example 700 associated with uplink power control for FD communications, in accordance with the present disclosure. As shown, example 700 includes a base station 110 and a UE 120, as described above in connection with FIG. 6A the following description.

[0101] As shown by reference number 705, the base station 110 can transmit (e.g., via RRC signaling) and the UE 120 can receive one or more filter configurations. The filter configurations can include information (e.g., a table, a mapping, and / or the like) that identifies one or more filters for processing a baseband signal (e.g., an unmodulated signal). The one or more filters can be low-pass filters. For example, a filter can attenuate a signal for a frequency (e.g., a sub-band) associated with an edge(s) of an uplink frequency band (e.g., a span of a lowest frequency of the uplink frequency band and / or a span of a highest frequency of the uplink frequency band, and / or the like). Different filters can provide different signal attenuation, thereby providing different variations in uplink transmit power across the uplink frequency band.

[0102] As shown by reference number 710, the base station 110 can transmit, and the UE 120 can receive, DCI. The DCI can indicate an uplink grant for the UE 120. For example, the DCI can schedule an uplink communication for the UE 120 at an uplink frequency within an uplink band (e.g., an uplink band of the FD resources). The DCI can schedule the uplink communication in resources that overlap in time with a downlink communication that is to be received by the UE 120 in one or more downlink bands, as described above in connection with FIG. 6. Further, the DCI can schedule the uplink communication in resources that overlap in frequency with the downlink communication, or in resources that do not overlap in frequency with the downlink communication, as described above in connection with FIG. 6.

[0103] In some aspects, the DCI can indicate a filter that the UE 120 is to use to process a baseband signal associated with the uplink communication. That is, the DCI can activate a particular filter of one or more filters configured for the UE 120. In some aspects, the base station 110 can indicate (e.g., activate) the filter that the UE 120 is to use to process the baseband signal via MAC-CE and / or RRC signaling. In some aspects, the base station 110 can determine the filter that the UE 120 is to use to process the baseband signal based at least in part on a location of the uplink frequency relative to the downlink band(s), as described below for the UE 120.

[0104] As shown by reference number 715, the UE 120 can determine a filter that the UE 120 is to use to process a baseband signal associated with the uplink communication. For example, the UE 120 can determine the filter in accordance with an indication (e.g., activation) provided by the base station 110 (e.g., in the DCI), as described above.

[0105] Additionally, or alternatively, the UE 120 can determine the filter based at least in part on a location of the uplink frequency relative to the downlink band(s). In some aspects, the UE 120 can determine the filter based at least in part on a size of a frequency separation between the uplink frequency and the downlink band(s). As an example, if the size of the frequency separation satisfies a first threshold, the UE 120 can select a first filter (e.g., associated with a first power attenuation), and if the size of the frequency separation satisfies a second threshold (or does not satisfy the first threshold), the UE 120 can select a second filter (e.g., associated with a second power attenuation).

[0106] For example, if the size of the frequency interval satisfies a third threshold (e.g., the size of the frequency interval is greater than a configured guard band size), the UE 120 can select a filter that provides a relatively small power attenuation at the edge(s) of the uplink frequency band (e.g., a span of the lowest frequencies of the uplink frequency band and / or a span of the highest frequencies of the uplink frequency band). For another example, if the size of the guard band (e.g., between the uplink frequency band and the downlink frequency band(s)) satisfies another threshold (e.g., the size of the guard band is less than some other threshold), the UE 120 can select a filter that provides a relatively large power attenuation at the edge(s) of the uplink frequency band. In some aspects, the uplink communication can not overlap in time with a downlink communication that the UE 120 is to receive. In this case, the UE 120 can determine that the filter will not be used to process the baseband signal. Other rules can also be used to determine the filter in addition to or instead of the examples described above.

[0107] In this way, the filter is selected such that if the uplink frequency and the downlink frequency band(s) are closer, the frequencies associated with the edge(s) of the uplink frequency band and thus closest to the downlink frequency band(s) can be associated with a relatively large power attenuation (or a relatively small power increase), and if the uplink frequency and the downlink frequency band(s) are farther, the frequencies can be associated with a relatively small power attenuation (or a relatively large power increase). For example, the UE 120 can use a lower power for frequencies closer to the downlink frequency band and a higher power for frequencies farther from the downlink frequency band.

[0108] As shown by reference number 720, the UE 120 can process the baseband signal associated with the uplink communication using the determined filter. As shown by reference number 725, the UE 120 can determine an uplink transmit power for the uplink communication. For example, the UE 120 can determine the uplink transmit power for the uplink communication according to Equation 1 described above.

[0109] As shown by reference number 730, at an uplink frequency in the uplink frequency band, the UE 120 can transmit and the base station 110 (or another base station 110) can receive an uplink communication. The UE 120 can transmit the uplink communication based at least in part on processing a baseband signal associated with the uplink communication using a filter. Further, the UE 120 can transmit the uplink communication using an uplink transmit power determined by the UE 120. Thus, the uplink transmit power used by the UE 120 can vary across the uplink frequency band (e.g., due to the processing of the baseband signal with the filter). Further, the UE 120 can receive a downlink communication (e.g., from the base station 110 or another base station 110) at the same time as transmitting the uplink communication. In this way, the UE 120 can use greater transmit power for the uplink communication and can reduce self-interference with the downlink communication, thereby improving performance of the uplink communication and the downlink communication.

[0110] As described above, FIG. 7 are provided by way of example. Other examples can differ from FIG. 7 what is described.

[0111] FIG. 8 FIG. 8 is a diagram illustrating an example process 800 performed, for example, by a UE, in accordance with the present disclosure.

[0112] As FIG. 8 shown, in some aspects, process 800 can include receiving DCI scheduling an uplink communication in an uplink frequency band (block 810). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or the like) can receive DCI scheduling an uplink communication in an uplink frequency band, e.g., as described above in connection with FIG. 6A , FIG. 6B and / or FIG. 7

For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, and / or the like) can transmit the uplink communication at the uplink frequency within the uplink frequency band with a power that varies across the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE, for example, as described above or below in connection with one or more other processes.

Additionally or alternatively, two or more of the blocks of the process 800 can be performed concurrently.

Optional aspects are illustrated with dashed lines. Process 1000 can enable a UE to be configured to apply different uplink power control parameters for different subbands.

FIG. 6A , FIG. 6B and / or FIG. 7 As described, the UE can transmit uplink transmissions at least partially based on a first set of one or more power control parameters via at least a first subband and at least partially based on a second set of one or more power control parameters via a second subband.
