[0003] public domain

[0004] Aspects of the present disclosure relate generally to wireless communications, and more particularly to techniques and apparatus for open loop power control (OLPC) parameter determination for a hybrid downlink control information (DCI) format.

[0005] background

[0006] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, 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 (3GPP).

[0007] A wireless network may include several base stations (BSs) capable of supporting communications for several user equipment (UEs). The UEs may communicate with the BSs via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "reverse link") refers to the communication link from the UE to the BS. As will be described in greater detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit / receive point (TRP), new radio (NR) BS, 5G Node B, and so on.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. NR (which may 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful.

[0031] Detailed description

[0032] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. Specifically, these aspects are provided to make the present disclosure thorough and complete, and they will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, regardless of whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using a supplement to the various aspects of the disclosure set forth herein or other other structures, functionality, or structure and functionality. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0033] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques are 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 a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0034] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0035] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, B node, gNB, 5G B node (NB), access point, transmit reception point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0036] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0037] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0038] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.

[0039] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0040] The network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. These BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), 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 (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0042] Some UEs may be considered machine type communication (MTC) UEs, 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., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0044] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary) using one or more sidelink channels. 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.

[0045] The devices of the wireless network 100 can communicate using an electromagnetic spectrum that can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) that can span 410 MHz to 7.125 GHz and / or can communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) can span 410 MHz to 7.125 GHz, and the second frequency range (FR2) can span 24.25 GHz to 52.6 GHz. 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, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as a "millimeter wave" band. Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz," etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," etc., if used herein, may broadly refer to 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 may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

[0046] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0047] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0048] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may 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 may also generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and frequency upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0049] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284 .

[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0051] The antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, etc. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include coplanar sets of antenna elements and / or non-coplanar sets of antenna elements. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements coupled to one or more transmit and / or receive components, such as Figure 2 One or more antenna elements of one or more components).

[0052] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may 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 the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 comprises a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 3-4 described.

[0053] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 3-4 described.

[0054] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with determining open loop power control (OLPC) parameters for a hybrid downlink control information (DCI) format, as described in greater detail elsewhere herein. Figure 2 Any other component(s) may perform or direct e.g. Figure 4 Method 400, Figure 5 Method 500, Figure 8 Method 800, Figure 9 Method 900, Figure 10 1000, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes 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, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 4 Method 400, Figure 5 Method 500, Figure 8 Method 800, Figure 9 Method 900, Figure 10 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other things.

[0055] In some aspects, a user equipment (UE) includes: a device for receiving downlink control information (DCI) for a physical uplink shared channel (PUSCH), wherein the DCI includes an indication of an open-loop power level associated with the PUSCH, wherein the DCI includes a single-bit indication field for the open-loop power level and a sounding reference signal resource indicator (SRI) field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including multiple open-loop power levels; a device for determining the open-loop power level from the multiple open-loop power levels based at least in part on the single-bit indication field and the SRI field; and / or a device for transmitting on the PUSCH using the open-loop power level. Means for a user equipment (UE) to perform the operations described herein may include, for example, one or more of an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, or a memory 282. In one example, the techniques and apparatus described herein may be applied to ultra-reliable low-latency communications. In some aspects, the UE may determine an open-loop power level based at least in part on a one-bit indication and an SRI. For example, the determination of the open-loop power level may be based at least in part on a preconfigured rule for resolving ambiguity. More specifically, the rule may indicate that the open-loop power level of the lowest index of the power parameter set is to be used.

[0056] In some aspects, the base station includes means for transmitting downlink control information (DCI) for a physical uplink shared channel (PUSCH), wherein the DCI includes an indication of an open-loop power level associated with the PUSCH, wherein the DCI includes a single-bit indication field for the open-loop power level and a sounding reference signal resource indicator (SRI) field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including a plurality of open-loop power levels; and / or means for receiving on the PUSCH, the PUSCH being transmitted at an open-loop power level determined from the plurality of open-loop power levels based at least in part on the single-bit indication field and the power parameter. Means for the base station to perform the operations described herein may include, for example, one or more of a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. In one example, the techniques and apparatus described herein may be applied to ultra-reliable low-latency communications. In some aspects, the UE may determine an open-loop power level based at least in part on a one-bit indication and an SRI. For example, the determination of the open-loop power level may be based at least in part on a preconfigured rule for resolving ambiguity. More specifically, the rule may indicate that the open-loop power level of the lowest index of a power parameter set is to be used.

[0057] although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented using a single hardware, software, or combined component or a combination of various components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0058] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0059] OLPC is a technique used by a UE to control its transmit power. In OLPC, the UE can perform power control without feedback from a base station. For example, the UE can receive a reference signal, estimate the signal strength of the reference signal, and adjust the UE's transmit power based at least in part on the signal strength and the UE's configuration. OLPC can be contrasted with closed-loop power control, in which the UE adjusts transmit power based on commands received from a base station indicating an increase or decrease in transmit power.

[0060] 5G / NR can support dynamic multiplexing of traffic associated with different services. For example, 5G / NR can support dynamic multiplexing of traffic associated with different priorities or quality of service identifiers, such as ultra-reliable low latency communication (URLLC) traffic and enhanced mobile broadband (eMBB) traffic. Dynamic multiplexing can include scheduling an emergency transmission (e.g., associated with a URLLC service) of a first UE on resources that overlap with a non-emergency transmission (e.g., associated with an eMBB service) of a second UE. In such a scenario, the BS can instruct the first UE to boost the transmit power for the emergency transmission to counteract interference from the non-emergency transmission.

[0061] The transmit power levels for boosted and non-boosted transmissions may be defined using OLPC power levels. An OLPC power level is a value indicating the transmit power (such as the nominal UE transmit power) used for OLPC operations associated with a given service. For example, an OLPC power level indicating the base transmit power for eMBB services may be referred to herein as P0. EMBB , the OLPC power level indicating the basic transmit power for URLLC service may be referred to herein as P0 URLLC , and the OLPC power level indicating the boosted transmit power for URLLC services (e.g., for URLLC transmissions that overlap with resources for eMBB transmissions) may be referred to herein as P0 URLLC,推升 . "eMBB service" may refer to a service associated with low priority traffic, and "URLLC service" may refer to a service associated with high priority traffic. For example, an eMBB service may be associated with a lower priority index than a URLLC service. The base station may dynamically indicate the above OLPC power level in the uplink grant for the corresponding transmission (e.g., using DCI format 0_1 ​​or 0_2). There are different mechanisms for indicating the OLPC power level, depending on whether SRI is configured in the DCI that schedules the PUSCH (e.g., uplink grant). The SRI field is a field in the DCI that may include a sounding reference signal (SRS) resource indicator. The SRS resource indicator is used to indicate the beam / precoder of the scheduled uplink transmission. In addition, the SRS resource indicator may be used by the base station to indicate a set of power control parameter sets (such as OLPC power level). For example, the SRS resource indicator may indicate an SRS resource set associated with the usage. The SRS may be configured using one or more SRS resource sets, where each set includes one or more SRS resources. The usage may be configured at a resource set granularity. For example, one SRS resource set may be configured for non-codebook based transmission, while another SRS resource set may be configured for downlink channel sounding. For some DCI formats (such as DCI format 0_1 ​​or DCI format 0_2), the SRI field may be configured (e.g., present) or not configured (e.g., not present).

[0062] However, if a UE is configured with DCI formats 0_1 and 0_2 (or any two DCI formats that can provide an indication of the OLPC power level for uplink transmissions), and only one of these DCI formats is configured with SRI, there may be ambiguity in how to interpret the OLPC power level indicated in the uplink grant, as described in more detail below.

[0063] If SRI is configured in the DCI format, the DCI format can only be configured with a one-bit OLPC parameter set indication field. In this case, for each SRI code point (i.e., each value that can be indicated in the SRI), the UE can be configured with a corresponding non-boosted power parameter set (e.g., P0-PUSCH-AlphaSet (P0-PUSCH-α set), which indicates the OLPC power level defined by the P0 value) and a corresponding boosted power parameter set (e.g., P0-PUSCH-set (P0-PUSCH-set), which indicates the OLPC power level defined by the P0 value). The P0 value indicated for the non-boosted power parameter set may represent the non-boosted transmit power, and the P0 value indicated for the boosted power parameter set may represent the boosted transmit power. In this case, for a given SRI, there may be no difference between the non-boosted power used for eMBB transmission and the non-boosted power used for URLLC transmission, and different SRI values ​​may be used to distinguish between eMBB and URLLC. For example, a first SRI value may be mapped to an SRS resource set for eMBB transmission, and a second SRI value may be mapped to an SRS resource set for URLLC transmission. The UE may receive a DCI carrying an SRI field. The SRI may indicate an SRS resource set configured with a P0-PUSCH-AlphaSet and a P0-PUSCH-set parameter set. For example, the value of the SRI field (e.g., a code point) may be mapped to a P0-PUSCH-set identifier value and a p0-PUSCH-alphaSet and a p0-PUSCH-alphaSet identifier value of a P0-PUSCH-set. The UE may first determine the corresponding P0-PUSCH-AlphaSet and P0-PUSCH-set parameter sets corresponding to the received code point in the SRI field (since the received code point points to an unboosted power parameter set and a boosted power parameter set), and then may determine which P0 value to use (e.g., from the boosted power parameter set indicated by P0-PUSCH-set and the unboosted power parameter set indicated by P0-PUSCH-AlphaSet) based at least in part on the one-bit OLPC parameter set indication field. For example, if the OLPC parameter set indication field indicates 0, the UE may use the P0 contained in P0-PUSCH-AlphaSet, and if the OLPC parameter set indication field indicates 1, the UE may use the P0 value configured in P0-PUSCH-set. Thus, the above-described techniques allow for the use of OLPC with a DCI configured with an SRI field. The following describes OLPC using a DCI without a configured SRI field.

[0064] If the SRI field is not configured in the DCI format, the UE may be configured with 1 or 2 bits for the OLPC parameter set indication field in the DCI. The UE may be configured with a P0-PUSCH-AlphaSet and a P0-PUSCH-Set, where up to two P0 values ​​may be configured in the P0-PUSCH-Set. If the OLPC parameter set indication field is "0" or "00", the UE may use P0 from the P0-PUSCH-AlphaSet. If the OLPC parameter set indication field is "1" or "01", the UE may use the first value in the P0-PUSCH-Set. If the OLPC indication field is "10", the UE may use the second value in the P0-PUSCH-Set.

[0065] If the SRI field is configured in one of DCI formats 0_1 and 0_2 but not in the other of DCI formats 0_1 and 0_2, the UE may be configured with more than one P0-PUSCH-set configuration (e.g., one configuration corresponding to the first of the two DCI formats and the other configuration corresponding to the second of the two DCI formats). In this case, if the UE is scheduled by a DCI format that does not include the SRI field, the UE may use the P0-PUSCH-set configuration with the lowest identifier (e.g., the first configured P0-PUSCH-set). In addition, if two bits are configured for the OLPC parameter set indication field in the DCI format (such as for a DCI format that does not include the SRI field), the UE may expect the parameter set P0-PUSCH-set with the lowest identifier to contain two P0 values. In this case, the OLPC parameter set indication fields "01" and "10" may be used to indicate which P0 value of the P0-PUSCH-Set to use (as described above).

[0066] However, in a DCI format with a configured SRI field, only a one-bit OLPC parameter set indication field may be configured (since only a one-bit OLPC parameter set indication field is configured for a DCI format with an SRI field). Therefore, if multiple P0 values ​​are configured, the DCI format may not be able to indicate which P0 value of the P0-PUSCH-Set to use. For example, if two P0 values ​​are configured in the P0-PUSCH-set with the lowest identifier, and if a UE is scheduled for PUSCH transmission via a DCI format with an SRI field (and a 1-bit OLPC parameter set indication field), and if the SRI field indicates the SRI value corresponding to the P0-PUSCH-set with the lowest identifier, the UE may not have sufficient information to determine which P0 value in the P0-PUSCH-set with the lowest identifier should be used to calculate the transmit power for the PUSCH transmission if the 1-bit OLPC parameter set indication field indicates a value of 1.

[0067] Some techniques and apparatus described herein provide solutions to ambiguities regarding the determination of a P0 value for a UE configured with at least two DCI formats, one of which is configured with an SRI field and the other of which is not. In a first approach, the UE may use the larger of the two P0 values ​​configured in the P0-PUSCH-set. Thus, the UE may use a boosted transmit power parameter set, thereby ensuring that overlapping URLLC transmissions are transmitted with sufficient power to overcome interference from overlapping eMBB transmissions. For example, if the value of the OLPC parameter set indication field is '1', the UE determines the value of P0 based on the larger of the P0 value(s) configured in the P0-PUSCH-Set having a p0-PUSCH-SetId value mapped to an SRI field value. In the second approach, the UE may use the lowest indexed or highest indexed P0 value, and the corresponding base station may configure the P0-PUSCH-set so that the boosted power is mapped to the P0 value that the UE is configured to use (for example, if the UE will automatically use the lowest indexed P0 value, the base station may map the boosted power parameter set to the lowest indexed P0 value, or if the UE will automatically use the highest indexed P0 value, the boosted power parameter set may be mapped to the highest indexed P0 value). The boosted power level may use a P0 value that is larger than the unboosted power level. This saves UE processing resources relative to the first approach. In the third approach, the base station may configure the DCI format so that no SRI code point in the DCI format configured with the SRI field is mapped to a P0-PUSCH-set containing multiple P0 values. In other words, a P0-PUSCH-set containing more than one P0 value can only be used for PUSCH transmissions scheduled by a DCI format that does not contain an SRI field.

[0068] Thus, the UE and / or BS can resolve or avoid ambiguity in the dynamic indication of OLPC for UEs configured with multiple DCI formats. In this way, the reliability of URLLC services is improved without significantly increasing overhead. In addition to resolving ambiguity, the proposed method also stipulates that the UE determines the P0 value so that the UE uses a sufficiently high transmit power to counter interference from other (eMBB) transmissions.

[0069] Figure 3 is a diagram illustrating an example 300 of signaling associated with open-loop power control parameter set determination for a hybrid downlink control information format in accordance with the present disclosure. As shown, example 300 includes a UE (eg, UE 120) and a base station (eg, BS 110).

[0070] As indicated by reference numeral 310, the base station may configure the UE. For example, the base station may transmit configuration information to the UE, such as via RRC signaling. As shown, the configuration information may indicate a configuration for a first DCI format and a configuration for a second DCI format. The configuration for the first DCI format may indicate that the first DCI format includes an SRI field and that the first DCI format includes a 1-bit OLPC parameter set indication field (sometimes referred to herein as a single-bit indication field). The OLPC parameter set indication field may indicate which set of open-loop power control parameter sets (such as P0-PUSCH-AlphaSet for unboosted or baseline transmit power or P0-PUSCH-Set for boosted transmit power) should be used to determine the transmit power for the PUSCH scheduled by the DCI. The configuration for the second DCI format may indicate that the second DCI format does not include an SRI field. In some aspects, the second DCI format may include a 1-bit OLPC parameter set indication field. In other aspects, the second DCI format may include a 2-bit OLPC parameter set indication field.

[0071] As further shown, the configuration information may indicate a configuration of a power parameter set indicated by the SRI field. For example, a power parameter set may indicate an open-loop power level (such as the value of P0 configured in the P0-PUSCH-Set), and multiple open-loop power levels may be configured for a given power parameter set. For example, a UE may be configured with more than one P0-PUSCH-Set configuration (one corresponding to a DCI with an SRI field and another corresponding to a DCI without an SRI field), which may result in multiple open-loop power levels being configured for an SRI value (e.g., codepoint) of the SRI field based at least in part on the UE being configured with one DCI format with an SRI field and another DCI format without an SRI field. In this case, if the SRI value indicates multiple open-loop power levels, an ambiguity arises as to which open-loop power level (i.e., which P0 value) should be used to transmit the PUSCH.

[0072] As indicated by reference numeral 320, the base station may transmit DCI to the UE. As further shown, the DCI utilizes a first DCI format, the SRI codepoint of the SRI field of the DCI indicates multiple open-loop power levels, and the OLPC parameter set indication field of the DCI includes only one bit, which cannot be used to distinguish which open-loop power level should be used. Here, the OLPC parameter set indication field is set to "1," which indicates that the UE should use the P0 value from the P0-PUSCH-Set (which is associated with the above ambiguity). If the OLPC parameter set indication field is set to "0," the UE may use the P0 value from the P0-PUSCH-AlphaSet.

[0073] As indicated by reference numeral 330, the UE may determine an open-loop power level. For example, the UE may determine the open-loop power level based at least in part on the SRI field and the single-bit indication field. As shown, the UE may select the lowest-indexed power level of a plurality of open-loop power levels indicated by the SRI field. For example, if the UE is configured in the P0-PUSCH-Set with a P0 value having an index of 0 associated with the SRI value of the SRI field and a P0 value having an index of 1 associated with the SRI value of the SRI field, the UE may select the P0 value having an index of 0. The base station may determine that the lowest-indexed power level should be selected. In some aspects, the base station may configure the lowest-indexed power level to use power boosting. For example, the lowest-indexed power level may have a higher power level than another power level, such as a higher-indexed power level of the P0-PUSCH-Set. Thus, the base station may ensure that the boosted transmit power is used under the conditions shown in example 300, which may facilitate transmission of higher priority PUSCHs with an acceptable level of reliability.

[0074] As indicated by reference numeral 340, the UE may transmit the PUSCH using an open-loop power level. For example, the UE may use the value of P0 selected at reference numeral 330 as an input to an open-loop power control formula. The open-loop power control formula may output a transmit power. The UE may transmit the PUSCH using this transmit power. In this manner, ambiguity associated with multiple open-loop power levels is resolved, which improves network reliability, reduces signaling overhead, and enables PUSCH transmission associated with a boosted power level (such as for URLLC communications, high-reliability communications, etc.).

[0075] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 Examples described.

[0076] Figure 4 is a diagram illustrating an example method 400, performed, for example, by a UE, in accordance with the present disclosure. Example method 400 is an example in which a UE (eg, UE 120) performs operations associated with open-loop power control parameter set determination.

[0077] like Figure 4 As shown in , in some aspects, method 400 may include receiving a DCI for a PUSCH, wherein the DCI includes an indication of an open-loop power level associated with the PUSCH, wherein the DCI includes a single-bit indication field for the open-loop power level and an SRI field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including a plurality of open-loop power levels (block 410). For example, the UE (e.g., using Figure 6

[0066] The receiving component 602 depicted in Figure 3 may receive scheduling information for a PUSCH via a DCI. The scheduling information may indicate an indication of an open-loop power level associated with the PUSCH, as described above. In some aspects, the DCI format of the DCI includes a single-bit indication field for the open-loop power level and an SRI field. In some aspects, multiple open-loop power levels are configured for the power parameter set indicated by the SRI field.

[0078] like Figure 4 As further shown in FIG. 4 , in some aspects, method 400 may include determining the open-loop power level from the plurality of open-loop power levels based at least in part on the single-bit indication field and the SRI field (block 420). For example, the UE (e.g., using Figure 6 A power control component 608 depicted in FIG) can determine an open-loop power level based on the indication and at least in part on the single-bit indication field and the SRI field, as described above.

[0079] like Figure 4 As further shown in FIG. 4 , in some aspects, method 400 may include transmitting on the PUSCH using the open loop power level (block 430). For example, the UE (e.g., using Figure 6 The transmission component 604 depicted in FIG. 6 may use open-loop power levels to transmit on the PUSCH, as described above.

[0080] Method 400 may include additional aspects, such as any single aspect or any combination of the aspects described below, and / or in conjunction with one or more other processes described elsewhere herein.

[0081] In the first aspect, determining the open-loop power level further comprises selecting a lowest-indexed power level of the plurality of open-loop power levels as the open-loop power level for transmitting on the PUSCH.

[0082] In a second aspect, alone or in combination with the first aspect, the lowest indexed power level is configured to be associated with the boosted power level.

[0083] In a third aspect, alone or in combination with one or more of the first and second aspects, the boosted power level is greater than a power level configured for another power level of the plurality of open-loop power levels.

[0084] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the indication of the single-bit indication field is 1.

[0085] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the single-bit indication field is an open-loop power control parameter set indication field.

[0086] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the multiple open-loop power levels are configured for a power parameter set indicated by the SRI field due to the UE being configured with a DCI format having the SRI field and another DCI format not having the SRI field.

[0087] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, determining the open loop power level comprises determining the open loop power level based at least in part on preconfigured rules.

[0088] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the preconfigured rule indicates that a lowest-indexed open-loop power level among the multiple open-loop power levels is to be selected as the open-loop power level for transmitting the PUSCH.

[0089] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the DCI format is a first DCI format, and method 400 further includes: receiving configuration information from a base station to configure the UE using the first DCI format and a second DCI format, wherein in the second DCI format, the DCI does not include the SRI field present in the first DCI format, and the DCI includes a two-bit indication field for the open-loop power level.

[0090] although Figure 4 Example blocks of method 400 are shown, but in some aspects, method 400 may include Figure 4 4. Additionally or alternatively, two or more blocks of method 400 may be executed in parallel.

[0091] Figure 5 is a diagram illustrating an example method 500, performed, for example, by a base station, in accordance with the present disclosure. Example method 500 is an example in which a base station (eg, base station 120) performs operations associated with open-loop power control parameter set determination.

[0092] like Figure 5 As shown in , in some aspects, method 500 may include transmitting a DCI for a PUSCH, wherein the DCI includes an indication of an open-loop power level associated with the PUSCH, wherein the DCI includes a single-bit indication field for the open-loop power level and an SRI field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including a plurality of open-loop power levels (block 510). For example, a base station (e.g., using Figure 7The transmitting component 704 depicted in FIG4 may transmit scheduling information for the PUSCH via a DCI. The scheduling information may indicate an indication of an open-loop power level associated with the PUSCH, as described above. In some aspects, a DCI format of the DCI includes a single-bit indication field for the open-loop power level and an SRI field, and multiple open-loop power levels are configured for the power parameter set indicated by the SRI field.

[0093] like Figure 5 As further shown in FIG. 5 , in some aspects, method 500 may include receiving on the PUSCH, the PUSCH transmitted at an open-loop power level determined from the plurality of open-loop power levels based at least in part on the single-bit indication field and the power parameter (block 520). For example, a base station (e.g., using Figure 7 1. The receiving component 702 depicted in FIG. 1 may receive on a PUSCH. The PUSCH may be transmitted at an open-loop power level determined from the plurality of open-loop power levels based at least in part on the single-bit indication field and the power parameter. In some aspects, the open-loop power level of the PUSCH uses a lowest-indexed power level of the plurality of open-loop power levels, as described above.

[0094] Method 500 may include additional aspects, such as any single aspect or any combination of the aspects described below, and / or in conjunction with one or more other processes described elsewhere herein.

[0095] In a first aspect, method 500 includes (e.g., using Figure 7 The configuring component 708) depicted in FIG. 1 configures the open loop power level of the PUSCH using the lowest indexed power level of the multiple open loop power levels.

[0145] Figure 10 is a diagram illustrating an example method 1000, performed, for example, by a base station, in accordance with the present disclosure. Example method 1000 is an example in which a base station (eg, BS 110, etc.) performs operations associated with open-loop power control parameter set determination for a hybrid downlink control information format.

[0146] like Figure 10 As shown in , in some aspects, method 1000 may include identifying an ambiguity regarding an indication of an open-loop power level based at least in part on a first DCI format and a second DCI format, wherein the first DCI format is associated with a sounding reference signal resource indicator field and the second DCI format is not associated with an SRI field, wherein the DCI is associated with the first DCI format and is configured with multiple open-loop power levels for a power parameter set that may be indicated by the SRI field, and wherein the first DCI format is associated with a single-bit indication field for the open-loop power level (block 1010).

The first DCI format may be associated with the SRI field and the second DCI format may not be associated with the SRI field. The DCI may be associated with the first DCI format and may be configured with multiple open-loop power levels for a power parameter set that may be indicated by the SRI field. The first DCI format may be associated with a single-bit indication field for the open-loop power level. In some aspects, the identification may be implicit (e.g., based at least in part on a wireless communication standard or a base station configuration that does not configure the SRI field such that the SRI field indicates a power parameter set for which multiple open-loop power levels are configured).

[0147] like Figure 10 As further shown in FIG. 1 , in some aspects, method 1000 may include configuring the SRI field such that the SRI field does not indicate the power parameter set for which the plurality of open-loop power levels are configured to resolve ambiguity (block 1020).

Thus, the base station may resolve ambiguity, as described above.
