[0003] Field of the Disclosure

[0004] Various aspects of the disclosure generally relate to wireless communication and to techniques and apparatuses for energy per resource element (EPRE) determination for sub-band full duplex (SBFD) communication.

[0005] BACKGROUND

[0006] 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).

[0007] 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. The downlink (or forward link) refers to the communication from the BS to the UE, and the uplink (or reverse link) refers to the communication from the UE to the BS. As will be described in more detail herein, a BS can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, and / or the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate on the same physical frequency channel. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 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 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

[0028] DETAILED DESCRIPTION

[0029] A UE and a base station can communicate based at least in part on an energy per resource element (EPRE). The EPRE identifies an energy level at a resource element (RE) granularity for uplink or downlink communications. The EPRE can be set and updated via radio resource control (RRC) signaling, for example, by modifying a set of parameters associated with the EPRE. However, in a sub-band full duplex (SBFD) deployment, a slot configuration (e.g., full duplex and half duplex) can change from slot to slot. RRC configuration or reconfiguration can not provide sufficient responsiveness for slot-to-slot modification of the EPRE. If the same EPRE is used for full duplex slots and half duplex slots, the base station and the UE can experience increased self-interference, power-limited scenarios, and curtailed throughput.

[0030] Some techniques and apparatuses described herein provide determination and / or signaling of EPRE on a slot-to-slot granularity, e.g., for transitioning between half duplex slots and full duplex slots. For example, a base station can configure separate EPRE values for half duplex slots and full duplex slots, can configure an offset for full duplex slot EPRE relative to half duplex slot EPRE, etc. Some UEs can determine whether to use full duplex slot EPRE or half duplex slot EPRE based at least in part on whether a slot is a full duplex slot or a half duplex slot, while other UEs can be configured or can receive a dynamic indication of whether to use full duplex slot EPRE (e.g., based at least in part on whether the UE is capable of determining whether a slot is a full duplex slot or a half duplex slot). Thus, slot-to-slot adjustment of EPRE based at least in part on full duplex slots and half duplex slots is provided. The slot-to-slot adjustment of EPRE can reduce self-interference at a base station and improve performance in full duplex mode, thereby increasing throughput, improving utilization of communication resources, and improving coverage, especially at cell edges.

[0031] Various aspects of the disclosure are described more fully below. However, the disclosure can be practiced with many types of embodiments and should not be construed as limited to any specific structure or function as set forth throughout this present disclosure. Rather, these aspects are provided as illustrative and explanatory so as to convey the scope of the disclosure to those skilled in the art. Based on the teachings provided herein, those skilled in the art will 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 apparatus or method which are practiced using, as alternative

[0032] 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 on the particular application and design constraints imposed on the overall system.

[0033] 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).

[0034] Figure 1 FIG. 1 is a diagram illustrating an example of a wireless network 100, in accordance with various aspects of the present disclosure. The wireless network 100 can be or can include elements of a 5G (NR) network and / or a 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 (UE) and can also be referred to as an NR BS, a NodeB, a gNB, a 5G nodeB (NB), an access point, a transmit receive point (TRP), and / 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 BS subsystem serving the coverage area, depending on the context in which the term is used.

[0035] BSs can be referred to as a macro BS, a pico BS, a femto BS, and / or a Figure 1 In the example shown in FIG. 1, the BSs 110a can be a macro BS for a macro cell 102a, the BS 110b can be a pico BS for a pico cell 102b, and the BS 110c can be a femto BS for a femto cell 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.

[0036] In some aspects, the cellular cells can not necessarily be stationary, and the geographic area of a cell can move based on the location of a mobile BS. In some aspects, the BSs can be interconnected to one another and / or to one or more other BSs 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.

[0037] Wireless 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. Figure 1 In the example shown, a 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.

[0038] 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. 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).

[0039] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with one another directly or indirectly via a wireless or wireline backhaul.

[0040] 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, biometric sensors / devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), 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.

[0041] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, 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 the 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

[0042] 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.

[0043] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this scenario, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0044] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2), where the first frequency range (FR1) spans from 410 MHz to 7.125 GHz and the second frequency range (FR2) spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, although distinct from the Extremely High Frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that, if used herein, the terms "sub-6 GHz" and the like can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that, if used herein, the terms "millimeter wave" and the like can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0046] Figure 2is a diagram illustrating an example 200 of a base station 110 in wireless network 100 in communication with a UE 120, in accordance with various aspects of 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.

[0047] 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 (MCSs) 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) or 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) 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.

[0048] At the UE 120, the antennas 252a through 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 through 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 through 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 channel quality indicator (CQI) parameters, among other examples. In some aspects, one or more components of UE 120 can be included in a housing.

[0049] 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.

[0050] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) can include or be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. 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 coupled to one or more transmit and / or receive components (such as one or more components of a transceiver 264 and / or a wireless communication management component 272). Figure 2 An antenna panel, antenna group, antenna element set, and / or antenna array can include one or more antenna elements coupled to one or more transmit and / or receive components (such as one or more components of a transceiver 264 and / or a wireless communication management component 272).

[0051] 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, as described with reference to FIGs. 1-2. Figures 3-10

[0052] 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 control information sent by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 can include a 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.

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 executed, or executed after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or base station 110 may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

Each time interval can be associated with a control region, illustrated as a darker shaded portion of the time interval, and / or a data region, shown as DL data for a downlink frequency region or a physical uplink shared channel (PUSCH) for an uplink frequency region. The uplink frequency region is illustrated using tighter dotting than the downlink frequency region.

[0057] A frequency division duplex (FDD) configuration can indicate one or more downlink frequency regions and one or more uplink frequency regions. For example, an 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, etc.). Examples of unpaired frequency bands include NR operating bands n40, n41, and n50. In some aspects, an 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. A BWP is a configured bandwidth that a UE can use for communication. A BWP can be configured for a UE and then activated for communication using downlink control information.

[0058] The bandwidths of the uplink frequency regions and the downlink frequency regions can or can not be equal. For example, in the example 300 shown in FIG. 3, the two downlink frequency regions shown by reference numbers 310 and 320 occupy a smaller bandwidth than the uplink frequency region shown by reference number 330. In this case, the uplink frequency region is provided between the downlink frequency regions, which can reduce interference from downlinks of other BSs 110 associated with frequencies of component carriers adjacent to example 300. Figure 3

[0059] ​The use of SBFD (also referred to as FDD in unpaired spectrum) can increase throughput and improve spectral efficiency, and can enable the use of always-on uplink (e.g., for URLLC control channels). For example, consider a downlink-downlink-special-uplink TDD configuration as a baseline, shown by reference number 340. This can be associated with, for example, a downlink cell edge rate of 22.5 Mbps and an uplink cell edge rate of 37.5 kbps (e.g., with user rates having a median of 2.5 Mbps, i.e., 20 dB less than the maximum coupling loss (MCL)). In this case, assuming that the power spectral density (PSD) is not increased to utilize the baseline power, SBFD with 80 MHz downlink and 20 MHz uplink can reduce the downlink cell edge spectral efficiency (SE) by 0.8. In such a case, 24-30 Mbps can be achievable with full duty cycle. The uplink UE SE can not change at the cell edge and at the median. In this case, 250 kbps can be achieved at the cell edge and 10 Mbps can be achieved at the median. Performance can be further improved for full duplex UEs. In this case, assuming the same parameters as the previous example, 30 Mbps of downlink throughput and 250 kbps of uplink throughput can be achieved concurrently. It should also be noted that the use of FDD in unpaired spectrum can improve the utilization of uplink resources, as a given UE cannot typically utilize the entire uplink bandwidth due to limitations on UE transmit power.

[0060] A base station can operate in a full duplex TDD mode. For example, the base station can switch between a full duplex TDD mode and a half duplex mode on a slot-to-slot basis. The base station can schedule communications with various half duplex or full duplex UEs. The base station can experience some amount of interference related to the full duplex TDD mode, e.g., due to self-interference between transmit and receive antennas of the base station, reflections from obstacles in the channel, or inter-cell interference. The base station can perform various techniques for canceling or canceling out the self-interference, such as antenna isolation (using physically separated antennas for transmission or reception), analog interference cancellation, digital interference cancellation, massive MIMO (M-MIMO) based beamforming cancellation for clutter reflections, and SBFD based on adjacent channel leakage ratio (ACLR) at least in part to achieve separation, among other examples. In SBFD, the downlink and uplink are in different parts of a frequency band or component carrier (CC). A guard band (GB) can be provided between the uplink and the downlink. Receive weight overlap and add (WOLA) operations can reduce ACLR leakage to the uplink signal. Analog low pass filters can improve analog-to-digital converter (ADC) dynamic range.

[0061] As indicated above, Figure 3are provided as examples. Other examples can differ from what is described Figure 3 The provided examples.

[0062] A UE and a base station can communicate based at least in part on energy per resource element (EPRE). EPRE identifies an energy level at a resource element (RE) granularity for uplink or downlink communications. EPRE can be configured as a ratio or offset relative to a signal with a known energy level, such that a receiver can determine the EPRE of another signal based at least in part on the known power. As one example, consider a synchronization signal block (SSB). EPRE can be constant across bandwidth and a secondary synchronization signal (SSS) carried on the SSB. The ratio of SSS EPRE to PBCH demodulation reference signal (DM-RS) EPRE can be 0 dB in some cases. SSS EPRE can be derived from a parameter (e.g., ss-PBCH-BlockPower):

[0063] ss-PBCH-BlockPower integer (-60..50),

[0064] As another example, consider a channel state information reference signal (CSI-RS). For CSI-RS, EPRE can be constant across a configured bandwidth and OFDM symbol. CSI-RS EPRE is derived via an offset. For example, a non-zero power (NZP) CSI-RS RE power offset relative to SSS RE can be defined by a parameter (e.g., powerControlOffsetSS):

[0065] powerControlOffsetSS enumerated {db-3, db0, db3, db6}

[0066] A physical downlink shared channel (PDSCH) RE power offset relative to NZP CSI-RS RE can be defined by a parameter (e.g., powerControlOffset, which can use values from -8 dB to 15 dB with a step size of 1 dB).

[0067] powerControlOffset integer (-8..15)

[0068] A base station can benefit from reducing EPRE during full duplex, or can be limited with respect to a maximum EPRE that can be used for full duplex operation. For example, because of a base station’s antenna panel operation, EPRE can be different in a full duplex slot than in a half duplex slot. In a half duplex slot, the entire antenna panel can be used for a transmit operation or a receive operation, while in a full duplex slot, a portion of the antenna panel can be used for a transmit operation and a portion of the antenna panel can be used for a receive operation. This can result in a variation of EPRE, for example, due to a maximum transmit power of the base station’s antenna panel or self-interference in a full duplex mode. For example, an increased EPRE in a full duplex slot can be associated with a smaller ACLR. Thus, a base station can benefit from reducing EPRE during a full duplex slot.

[0069] EPRE can be set and updated via radio resource control (RRC) signaling, for example, by modifying the parameters shown above. However, in SBFD, the slot configuration (e.g., full duplex or half duplex) can change from slot to slot. RRC configuration or reconfiguration can not provide sufficient responsiveness for slot-to-slot modification of EPRE. If the same EPRE is used for full duplex slots and half duplex slots, the base station and UEs can experience increased self-interference, power-limited scenarios, and curtailed throughput.

[0070] Some techniques and apparatuses described herein provide determination and / or signaling of EPRE at slot-to-slot granularity, for example, for transitioning between half duplex slots and full duplex slots. For example, a base station can configure separate EPRE values for half duplex slots and full duplex slots, can configure an offset of full duplex slot EPRE relative to half duplex slot EPRE, and so on. Some UEs can determine whether to use full duplex slot EPRE or half duplex slot EPRE based at least in part on whether a slot is a full duplex slot or a half duplex slot, while other UEs can be configured or can be dynamically indicated as to whether to use full duplex slot EPRE (e.g., based at least in part on whether the UE is capable of determining whether a slot is a full duplex slot or a half duplex slot). Further, full duplex slot EPRE can be associated with a constant SSB EPRE, and an EPRE offset from PDSCH to demodulation reference signal (DMRS) and NZP-CSI-RS can be defined, enabling consistent SSB transmit power across all UEs while modifying the transmit power of PDSCH, DMRS, and / or CSI-RS for full duplex operation. Thus, slot-to-slot adjustment of EPRE based at least in part on full duplex slots and half duplex slots is provided. The slot-to-slot adjustment of EPRE can reduce self-interference at a base station and improve performance in a full duplex mode, increasing throughput, improving utilization of communication resources, and improving coverage, especially at cell edges.

[0071] Figure 4 is a diagram illustrating an example 400 of determining an EPRE value for full duplex slots and / or half duplex slots, in accordance with various aspects of the present disclosure. As shown, the example 400 includes a full duplex (FD) UE 120 and a half duplex (HD) UE 120, as well as a BS 110. The FD UE 120 can be capable of FD communication in a slot. In the example 400, the HD UE 120 can not be able to determine whether a slot is an HD slot or an FD slot. For example, the HD UE 120 can be a legacy UE. In some aspects, the HD UE 120 can not determine whether a slot is an HD slot or an FD slot (e.g., regardless of whether the HD UE 120 is capable of doing so).

[0072] As shown, the example 400 involves an FD slot 405 and an HD slot 410. Operations shown within the dashed box labeled “FD slot 405” can occur within or can be related to an FD slot, and operations shown within the dashed box labeled “HD slot 410” can occur within or can be related to an HD slot. Figures 4-8 Operations shown within the dashed box in can not necessarily occur within a single slot.

[0073] As shown by reference number 415, the BS 110 can provide configuration information (e.g., RRC configuration information, etc.) to the FD UE 120 and / or the HD UE 120. In some aspects, the BS 110 can provide the configuration information to both the FD UE 120 and the HD UE 120. In some aspects, the BS 110 can provide the configuration information to only one of the FD UE 120 and the HD UE 120. The configuration information can indicate a value of an FD slot EPRE (e.g., an EPRE value to be used for communications in an FD slot). In some aspects, the configuration information can identify a reduction (e.g., an offset) relative to an HD slot EPRE (e.g., a baseline EPRE), such as a reduction of X dB. For example, X can be based at least in part on an interference cancellation capability of the BS 110, a panel configuration in the FD slot, etc. In some aspects, a UE (e.g., the FD UE 120 or the HD UE 120) can be preconfigured with a value of the FD slot EPRE or an offset of the FD slot EPRE relative to the HD slot EPRE. For example, the value can be specified by a wireless communication standard, can be configured by an original equipment manufacturer or the UE, can be indicated in system information, etc.

[0074] As shown by reference number 420, the FD UE 120 can determine the EPRE for the FD slot based at least in part on the slot being an FD slot and based at least in part on the RRC configuration. For example, the FD UE 120 can determine that the FD slot is an FD slot (e.g., based on receiving signaling indicating that the FD slot is an FD slot, based at least in part on identifying information indicating a slot pattern that indicates that the FD slot is an FD slot, and / or the like). Accordingly, the FD UE 120 can determine that the EPRE for the FD slot is to be used. For example, the FD UE 120 can determine the EPRE for the FD slot based at least in part on the configuration information (e.g., based at least in part on configuration information explicitly identifying the EPRE for the FD slot or based at least in part on applying an offset or reduction to the EPRE for the HD slot to determine the EPRE for the FD slot).

[0075] As shown by reference number 425, the BS 110 can use a constant EPRE (e.g., an HD slot EPRE) for the HD UE 120. For example, the BS 110 can not modify the HD slot EPRE for legacy UEs because the legacy UEs can not be able to determine whether a given slot is an HD slot or an FD slot. As such, the BS 110 can use different EPREs for different UEs (e.g., the FD UE 120 and the HD UE 120) based at least in part on the capabilities of the different UEs. For examples related to the HD UE 120 that can determine whether a slot is an HD slot or an FD slot, refer to Figure 5 .

[0076] As shown by reference number 430, the BS 110 can perform communications with the FD UE 120 and the HD UE 120. The communications can include a single communication to both UEs 120 or respective communications for the two UEs. As further shown, the communications can use the FD slot EPRE for the FD UE 120 and a constant EPRE (e.g., an HD slot EPRE) for the HD UE 120. The FD UE 120 can perform the communications using the FD slot EPRE. For example, the FD UE 120 can identify an EPRE for a received communication based at least in part on a reference signal and the FD slot EPRE, which can identify an offset between a power of the reference signal and a power of the received communication. The FD UE 120 can receive or decode the communication based at least in part on the EPRE of the received communication.

[0077] Referring now to the HD slot 410, as shown by reference number 435, the FD UE 120 can determine the EPRE based at least in part on determining that the HD slot is an HD slot and based at least in part on the RRC configuration. For example, the FD UE 120 can determine that the HD slot is an HD slot. The FD UE 120 can determine that the reduction will not be applied to the HD slot EPRE or that the FD slot EPRE will not be used for the HD slot 410. For example, the FD UE 120 can determine this on a slot-to-slot basis or without RRC reconfiguration of the HD slot EPRE and / or the FD slot EPRE.

[0078] As shown by reference number 440, the BS 110 can use a constant EPRE (e.g., an HD slot EPRE) for the HD UEs 120 (e.g., legacy UEs 120). As shown by reference number 445, the BS 110 can transmit one or more communications to the FD UE 120 and the HD UEs 120 using the HD slot EPRE. As such, the FD slot EPRE or the HD slot EPRE can be used on a slot-to-slot granularity, enabling slot-to-slot adjustment of the EPRE, reducing interference at the BS 110, and reducing overhead and latency associated with RRC signaling to reconfigure the EPRE.

[0079] As indicated above, Figure 4 are provided by way of example. Other examples can differ from those described. Figure 4

[0080] Figure 5 is a diagram illustrating an example 500 of determining EPRE values for full duplex slots and / or half duplex slots, in accordance with various aspects of the present disclosure. As shown, the example 500 includes a FD UE 120 and a BS 110. The FD UE 120 is described in connection with the Figure 4 is described in greater detail. As further shown, the example 500 includes a HD UE 120. Figure 5 The HD UE 120 of the example 500 can be capable of determining whether a slot is an FD slot or an HD slot (e.g., in a similar manner as the FD UE 120) when operating in a half duplex mode.

[0081] As shown by reference number 505, the BS 110 can provide configuration information (e.g., RRC configuration information, etc.) to the FD UE 120 and / or the HD UE 120. For example, the configuration information can identify the FD slot EPRE and / or the HD slot EPRE, as described in greater detail elsewhere herein.

[0082] ​As shown by reference numbers 510 and 515, the FD UE 120 and the HD UE 120 can determine the EPRE for the FD slot. For example, the FD UE 120 can determine that the FD slot EPRE is to be used based at least in part on identifying the FD slot as an FD slot. Further, the FD UE 120 and the HD UE 120 can determine the FD slot EPRE based at least in part on the configuration information shown by reference number 505. Accordingly, the BS 110 can communicate with the FD UE 120 and / or the HD UE 120 in accordance with the FD slot EPRE.

[0083] Referring now to the HD slot, as shown by reference numbers 525 and 530, the FD UE 120 and the HD UE 120 can determine the EPRE for the HD slot. For example, the FD UE 120 can determine that the HD slot EPRE is to be used based at least in part on identifying the HD slot as an HD slot. Accordingly, as shown by reference number 535, the BS 110 can communicate with the FD UE 120 and / or the HD UE 120 in accordance with the HD slot EPRE.

[0084] As indicated above, Figure 5 are provided by way of example. Other examples can differ from those described Figure 5 without departing from the spirit of the disclosure.

[0085] Figure 6 is a diagram illustrating an example 600 of determining EPRE values for full- duplex slots and / or half-duplex slots, in accordance with various aspects of the present disclosure. In example 600, the FD slot EPRE is explicitly indicated to the FD UE 120 and / or the HD UE 120. For example, as shown by reference number 610, the BS 110 can provide an indication of the FD slot EPRE to the FD UE 120 and the HD UE 120. In some aspects, the indication can directly identify the FD slot EPRE (e.g., can provide a value to be used as the FD slot EPRE), which provides greater flexibility in the EPRE configuration than an offset-based approach. In some aspects, the indication can identify an offset from the HD slot EPRE (e.g., a ratio or reduction with respect to the HD slot EPRE), which can provide higher resolution in the EPRE configuration than a direct indication-based approach. In some aspects, the indication can comprise, for example, a downlink control information (DCI), a medium access control (MAC) control element (CE), and / or the like. As shown by reference number 620, the BS 110 can communicate with the FD UE 120 and / or the HD UE 120 in accordance with the FD slot EPRE.

[0086] As indicated above, Figure 6are provided as examples. Other examples can differ from what is described with respect to at least one of the described examples. Figure 6

[0087] Figure 7 is a diagram illustrating an example 700 of determining an EPRE value for a full-duplex slot and / or a half-duplex slot, in accordance with various aspects of the present disclosure. As shown, the example 700 includes a UE 120. The UE 120 can be an FD UE 120 or an HD UE 120 (e.g., an HD UE 120 capable of determining whether a slot is an FD slot or an HD slot). The example 700 illustrates an example related to determining an FD slot EPRE in a situation where an indication or configuration of an updated FD slot EPRE is missed by the UE 120.

[0088] As shown by reference number 710, the UE 120 can not receive a message indicating a value or an update regarding an FD slot EPRE. For example, the UE 120 can fail to detect the message. As such, as shown by reference number 720, the UE 120 can determine an FD slot EPRE to be used for an FD slot. In some aspects, the UE 120 can determine the FD slot EPRE based at least in part on a previous EPRE. For example, the UE 120 can use a last (e.g., most recent) signaled FD slot EPRE for the FD slot EPRE of the example 700. In some aspects, the UE 120 can determine the FD slot EPRE based at least in part on a default value. For example, if no updated FD slot EPRE is received for an FD slot, the BS 110 can configure (e.g., using RRC signaling, etc.) the UE 120 with a default FD slot EPRE value to use. In some aspects, the UE 120 can determine the FD slot EPRE based at least in part on a preconfigured value, such as a value specified by a radio signaling standard, an original equipment manufacturer, etc. In this case, as one example, the value can be 3 dB, although other values can also be used. As shown by reference number 730, the BS 110 can communicate with the UE 120 based at least in part on the FD slot EPRE. In some aspects, the BS 110 can determine the FD slot EPRE used by the UE 120 (e.g., based at least in part on receiving a negative acknowledgment of an indication or configuration of an FD slot EPRE). In some aspects, the BS 110 can transmit a communication to the UE 120 without a determined FD slot EPRE.

[0089] As indicated above, Figure 7 are provided as examples. Other examples can differ from what is described with respect to at least one of the described examples. Figure 7

[0090] Figure 8 ​​is a diagram illustrating an example 800 of determining an EPRE value for full duplex slots and / or half duplex slots according to various aspects of the present disclosure. As shown, example 800 includes a UE 120. The UE 120 can be an FD UE 120 or an HD UE 120 (e.g., an HD UE 120 capable of determining whether a slot is an FD slot or an HD slot). Example 800 illustrates an example related to an indication of a selected EPRE from a plurality of configured EPREs.

[0091] As shown by reference number 810, the BS 110 can provide configuration information to the UE 120. As further shown, the configuration information can identify a plurality of EPREs. For example, the configuration information can identify values of the plurality of EPREs, respective offsets for the plurality of EPREs, and / or the like. In some aspects, the configuration information can indicate an EPRE based at least in part on an offset relative to a reference signal. For example, the configuration information can indicate an offset of an EPRE relative to an SSB, an offset of a PDSCH to a CSI-RS, an offset of a PDSCH to a DMRS, and / or the like.

[0092] In some aspects, the BS 110 can use a constant EPRE for SSBs (as SSBs are transmitted to FD UEs and legacy UEs) and the configuration information can identify one or more offsets used to determine EPREs for other communications (e.g., DMRS, PDSCH, NZP-CSI-RS, and / or the like). For example, the configuration information can indicate a table of EPRE offsets from PDSCH to DMRS, a table of FD slot EPRE offsets between NZP-CSI-RS and SSS, a table of FD slot EPRE offsets between PDSCH and NZP-CSI-RS, and / or the like. The configuration information can indicate only FD slot EPREs, only HD slot EPREs, or a combination of one or more FD slot EPREs and one or more HD slot EPREs.

[0093] As shown by reference number 820, the UE 120 can receive DCI indicating a selected EPRE. For example, the BS 110 can dynamically indicate an FD slot EPRE for an FD slot. In some aspects, the DCI can be associated with scheduling a PDSCH on the FD slot. In some aspects, the DCI can be separate from scheduling DCI for the FD slot. In some aspects, the DCI can relate to multiple slots and / or multiple UEs. For example, the DCI can indicate respective EPREs for multiple slots and / or multiple UEs. The indication of the selected EPRE can include one or more bits, where a greater number of bits can be used for a greater set of potential EPREs. As shown by reference number 830, the BS 110 can communicate with the UE 120 based at least in part on the selected EPRE. By configuring multiple EPREs and indicating a selected EPRE, overhead can be reduced relative to explicitly indicating a value of the selected EPRE.

[0094] As indicated above, Figure 8 are provided by way of example. Other examples can differ from those described. Figure 8 are provided by way of example. Other examples can differ from those described.

[0095] Figure 9 is a diagram illustrating an example process 900 performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 900 is an example where the UE (e.g., UE 120, HD UE 120, FD UE 120, etc.) performs operations associated with EPRE determination for sub-band full duplex communication.

[0096] As Figure 9 shown in FIG. 13C, in some aspects, process 900 can include determining an EPRE value for the slot based at least in part on whether the slot is associated with a half duplex configuration or a full duplex configuration, where the EPRE value is a first value when the slot is associated with the half duplex configuration and is a second value when the slot is associated with the full duplex configuration (block 910). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) can determine an EPRE value for the slot based at least in part on whether the slot is associated with a half duplex configuration or a full duplex configuration, as described above. In some aspects, the EPRE value is a first value (e.g., an HD slot EPRE) when the slot is associated with the half duplex configuration and is a second value (e.g., an FD slot EPRE) when the slot is associated with the full duplex configuration. In some aspects, the full duplex configuration can be associated with a base station, such as a base station that the UE is communicating with.

[0097] As Figure 9As further shown in Fig. 9, in some aspects process 900 can include performing, in accordance with the EPRE value, a communication in the slot (block 920). 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 perform, in accordance with the EPRE value, a communication in the slot, as described above.

[0098] Process 900 can include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.

[0099] In a first aspect, the UE is a full-duplex UE, and determining the EPRE value is based at least in part on a determination of whether the slot is associated with a full-duplex configuration.

[0100] In a second aspect, alone or in combination with the first aspect, process 900 includes receiving configuration information indicating one or more of the first value or the second value.

[0101] In a third aspect, alone or in combination with one or more of the first and second aspects, one or more of the first value or the second value is preconfigured.

[0102] In a fourth aspect, alone or in combination with one or more of the first through third aspects, the EPRE value is based at least in part on at least one of an interference cancellation capability of the base station or a panel configuration for the full-duplex configuration.

[0103] In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, process 900 includes, for the EPRE value, switching from the first value to the second value based at least in part on switching from a slot associated with a full-duplex configuration to a slot associated with a half-duplex configuration or switching from a slot associated with a half-duplex configuration to a slot associated with a full-duplex configuration, or switching from the second value to the first value.

[0104] In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the UE is a half-duplex UE, and determining the EPRE value is based at least in part on receiving information indicating the EPRE value for the slot.

[0105] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the UE is a half-duplex UE, and determining the EPRE value is based at least in part on a determination of whether the slot is associated with the full-duplex configuration.

[0106] In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, process 900 includes receiving, from the base station, information indicating the EPRE value for the slot.

[0107] In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, process 900 includes receiving, from the base station, information indicating the EPRE value based at least in part on an offset from the second value.

[0108] In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, determining the EPRE value further includes determining a reduced EPRE value relative to a baseline EPRE value based at least in part on determining that the information indicating the EPRE value is not received.

[0109] In an eleventh aspect, alone or in combination with one or more of the first through tenth aspects, the reduced EPRE value is based at least in part on a previous EPRE value for a full-duplex configuration.

[0110] In a twelfth aspect, alone or in combination with one or more of the first through eleventh aspects, the reduced EPRE value is based at least in part on a configured EPRE value for a full-duplex configuration.

[0111] In a thirteenth aspect, alone or in combination with one or more of the first through twelfth aspects, the reduced EPRE value is based at least in part on a fixed EPRE value for a full-duplex configuration.

[0112] In a fourteenth aspect, alone or in combination with one or more of the first through thirteenth aspects, determining the EPRE value further includes determining the EPRE value based at least in part on received signaling indicating the EPRE value from a plurality of configured EPRE values.

[0113] In a fifteenth aspect, alone or in combination with one or more of the first through fourteenth aspects, the plurality of configured EPRE values are associated with information indicating respective offsets for the plurality of configured EPRE values relative to at least one of a synchronization signal block, a channel state information reference signal, or a demodulation reference signal.

[0114] In a sixteenth aspect, alone or in combination with one or more of the first through fifteenth aspects, the slot is associated with a constant synchronization signal block power relative to an adjacent slot, and the respective offset is an offset for the full-duplex configuration relative to the first value associated with the half-duplex configuration.

[0115] In a seventeenth aspect, alone or in combination with one or more of the first through sixteenth aspects, the received signaling includes downlink control information associated with the slot.

[0116] Although Figure 9 Example blocks of process 900 are illustrated, but in some aspects, process 900 can include more blocks, fewer blocks, different blocks, or different orders of blocks than those depicted in FIG. 9. Figure 9The blocks in the diagram are depicted as serially arranged, but that is for clarity only as some blocks in fact can be performed concurrently. In some aspects, one or more of the blocks of process 900 can be performed in parallel with one or more of the other blocks.
