UPLINK POWER CONTROL CONFIGURATION

Abstract

Various aspects of the present disclosure relate to uplink power control configuration. An apparatus, such as a user equipment (UE), receives a configuration message for uplink power control, the configuration message indicating one or more uplink power control parameter sets each associated with a different time resource type. The UE transmits, based at least in part on the configuration message and according to the one or more uplink power control parameter sets, an uplink transmission using a first uplink transmit power for the uplink transmission during a first time resource type and using a second uplink transmit power during a second time resource type.

DETAILED DESCRIPTION

Wireless communications systems can utilize duplexing modes for transmitting and receiving data, such as at a UE. For instance, time division duplex (TDD) and frequency division duplex (FDD) are two duplexing modes used by some current wireless networks. TDD uses a same carrier frequency and splits the time resources between the downlink (DL) and uplink (UL) communications. FDD enables simultaneous UL and DL communications and using different carrier frequencies. Further, full duplex (FD) mode enables simultaneous UL and DL communications over the same carrier frequency and same time resource. FD mode can enable gains and enhancements in terms of increasing the system capacity and coverage and/or reducing latency, such as compared to the half-duplex TDD and FDD modes. However, when using the same time and frequency resources for UL and DL communication such as in FD mode, SI and cross link interference (CLI) issues can arise which can reduce signal quality and increase signal latency.

Accordingly, aspects of the disclosure are directed to supporting UL and DL quality of service (QoS) targets in FD modes using efficient UL power control selection and adaptation such as in accordance with CLI and SI level changes at both UEs and serving gNBs. For instance, in implementations a UE receives, from its serving network node (e.g., a serving gNB), a configuration message containing one or more power control parameter sets to be used for determining the UL power (e.g., for a Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signals (SRS), and a Physical Random Access Channel (PRACH) transmission) for a plurality of time resource (e.g., symbols and/or slots) sets. The power control parameter sets contain, at least, one different parameter value, e.g., different open-loop parameters and/or different fractional pathloss compensation factor. In at least some implementations, the configuration message explicitly configures each power control parameter set. Alternatively or additionally the configuration message explicitly configures a first power control parameter set and the offset value of one or more parameters to be used when determining the one or more of second power control parameter sets. The UE can utilize the power control parameter sets for transmitting uplink transmissions.

By utilizing the described techniques, QoS goals in data transmission and data reception can be achieved such as by reducing CLI and SI at both UEs and serving cells, e.g., serving gNBs.

Aspects of the present disclosure are described in the context of a wireless communications system.

FIG. 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more NE 102, one or more UE 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a NR network, such as a 5G network, a 5G-Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc.

The one or more NE 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NE 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a network function, a network entity, a radio access network (RAN), a NodeB, an eNodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.

An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a satellite associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.

The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples.

A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or more backhaul links (e.g., S1, N2, N6, or other network interface). In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other indirectly (e.g., via the CN 106). In some implementations, one or more NE 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs).

The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management functions (AMF)) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc.) for the one or more UEs 104 served by the one or more NE 102 associated with the CN 106.

The CN 106 may communicate with a packet data network over one or more backhaul links (e.g., via an S1, N2, N6, or other network interface). The packet data network may include an application server. In some implementations, one or more UEs 104 may communicate with the application server. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server using the established session (e.g., the established PDU session). The PDU session may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106).

In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communications). In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures). The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.

One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames). Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.

Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., orthogonal frequency division multiplexing (OFDM) symbols). In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing), a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.

In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz-7.125 GHz), FR2 (24.25 GHz-52.6 GHz), FR3 (7.125 GHz-24.25 GHz), FR4 (52.6 GHz-114.25 GHz), FR4a or FR4-1 (52.6 GHz-71 GHz), and FR5 (114.25 GHz-300 GHz). In some implementations, the NEs 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data). In some implementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.

FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies). For example, FR1 may be associated with a first numerology (e.g., μ=0), which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1), which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2), which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies). For example, FR2 may be associated with a third numerology (e.g., μ=2), which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3), which includes 120 kHz subcarrier spacing.

According to implementations, one or more of the NEs 102 and the UEs 104 are operable to implement various aspects of the techniques described with reference to the present disclosure. For example, a UE 104 receives, from a NE 102, a configuration message for uplink power control, where the configuration message indicates one or more uplink power control parameter sets each associated with a different time resource type. The UE 104 then transmits, based at least in part on the configuration message and according to the one or more uplink power control parameter sets, an uplink transmission using a first uplink transmit power for the uplink transmission during a first time resource type and using a second uplink transmit power during a second time resource type.

With reference to transmission in wireless communications systems, TDD and FDD are two duplexing modes used by current wireless networks. TDD uses the same carrier frequency but splits the time resources between the DL and uplink (UL) communications. FDD enables simultaneous UL and DL communications, but using different carrier frequencies. Full duplex (FD) mode enables simultaneous UL and DL communications over the same carrier frequency and same time resource.

FIG. 2 illustrates a scenario 200 for wireless communications. The scenario 200, for instance illustrates that CLI and SI can occur in a FD mode. In a FD mode, using the same time and frequency resources for UL and DL communications, (e.g., as in FD mode) can cause SI and CLI issues as illustrated in the scenario 200, which are defined as follows. Self-interference (SI): where the transmitted DL/UL signal by a network node (e.g., gNB or UE) leaks energy onto its received UL/DL signal. Cross-link interference (CLI): where the transmitted DL/UL signal by a network node (e.g., gNB or UE) leaks energy onto received UL/DL signal of a nearby node.

To optimize usage of the FD mode, SI and CLI are to be properly managed. One solution to the SI and CLI issues is to split the frequency resources of a time resource into non-overlapping DL and UL subbands (SBs), where each subband includes one or more resource-blocks (RBs). Such an approach can reduce the impact of SI and CLI and has been introduced as a study item within 3GPP Rel-18 and called non-overlapping SBFD. Other solutions to handle SI and CLI include the use of different antenna panels for DL and UL communications, coordination for scheduling spatial domain, advance receivers, beam nulling, and UL and DL power control (PC).

FIG. 3 illustrates a scenario 300 for wireless communications. The scenario 300, for instance, illustrates time slot resources splitting between SBFD-based and non-SBFD-based slots. In time domain, some of the time resources (e.g., symbols or slots) may be used for SBFD communications, while others can be used for half-duplex (HD) DL or UL communications, such as illustrated in the scenario 300. Such time resources-based division is beneficial in some scenarios, e.g., to protect some DL or UL signals/channels from the impacts of SI and/or CLI. For example, in the scenarios where the resource scheduler (e.g., the gNB) is expecting high SI and/or CLI levels, the gNB may schedule the high-priority UL signals on a non-SBFD slot (e.g., slot #2 in the scenario 300), and schedule low-priority UL signals on the UL subband (SB) of a SBFD slot (e.g., slot #1 in the scenario 300).

For instance, in such scenarios, the expected signal-to-interference and noise ratio (SINR) at the receiver of the gNB is likely to be very low due to the anticipated high SI and/or CLI levels. However, in some other scenarios, the gNB may schedule the high-priority UL signals on the UL SB of a SBFD slot, as it may anticipate low SI and/or CLI levels. For example, the gNB may decide to use a highly efficient SI and/or CLI managing technique on one or more SBFD slots. The target gNB, for instance, can use an advance receiver technique and/or the nearby gNBs use a beam nulling transmit precoding technique. In such cases, the gNB may expect low SI and/or CLI levels, allowing the high-priority UL signals/channels to be scheduled on these SBFD slots. Such an operation may benefit from better UL transmission parameters scheduling, configuration, and selection.

In wireless communications systems, uplink power control can determine a power for PUSCH, PUCCH, SRS, and PRACH transmissions. For instance, if a UE transmits a PUSCH on active UL bandwidth part (BWP) b of carrier f of serving cell c using parameter set configuration with index j and PUSCH power control adjustment state with index l, the UE can determine the PUSCH transmission power P_PUScH,b,f,c(i,j,q_d,l) in dBm in PUSCH transmission occasion i as

$P_{\mathrm{PUSCH},b,f,c}\left(i,j,q_d,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c}\left(i\right),\\ P_{O\_\mathrm{PUSCH},b,f,c}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUSCH}}\left(i\right)\right)+\\ {\alpha }_{b,f,c}\left(j\right)·{\mathrm{PL}}_{b,f,c}\left(q_d\right)+{\Delta }_{\mathrm{TF},b,f,c}\left(i\right)+f_{b,f,c}\left(i,l\right)\end{array}\right\}$

If a UE transmits a PUCCH on active UL BWP b of carrier f in the primary cell c using PUCCH power control adjustment state with index l, the UE determines the PUCCH transmission power P_PUCCH,b,f,c(i,q_u,q_d,l) in dBm in PUCCH transmission occasion i as

$P_{\mathrm{PUCCH},b,f,c}\left(i,q_u,q_d,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c}\left(i\right),\\ P_{O\_\mathrm{PUCCH},b,f,c}\left(q_u\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUCCH}}\left(i\right)\right)+\\ {\mathrm{PL}}_{b,f,c}\left(q_d\right)+{\Delta }_{F\_\mathrm{PUCCH}}\left(F\right)+{\Delta }_{\mathrm{TF},b,f,c}\left(i\right)+g_{b,f,c}\left(i,l\right)\end{array}\right\}$

If a UE transmits SRS based on a configuration by SRS-ResourceSet on active UL BWP b of carrier f of serving cell c using SRS power control adjustment state with index l, the UE determines the SRS transmission power P_SRS,b,f,c(i,q_s,l) in dBm in SRS transmission occasion i as

$P_{\mathrm{SRS},b,f,c}\left(i,q_s,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c}\left(i\right),\\ P_{O\_\mathrm{SRS},b,f,c}\left(q_s\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{SRS},b,f,c}\left(i\right)\right)+\\ {\alpha }_{\mathrm{SRS},b,f,c}\left(q_s\right)·{\mathrm{PL}}_{b,f,c}\left(q_d\right)+h_{b,f,c}\left(i,l\right)\end{array}\right\}$

Example definitions for the parameters described above can be found in section 7 of 3GPP Technical Specification (TS) 38.213 (V18.0.0).

Accordingly, in aspects of this disclosure, techniques are disclosed to enable meeting UL and DL QoS (quality of service) targets by efficient UL power control selection and adaptation in accordance to CLI and SI levels change at both UE and serving gNB.

In implementations a UE receives, from its serving network node (e.g., a serving gNB), a configuration message containing one or more power control parameter sets to be used for determining the UL power (e.g., for a PUSCH, PUCCH, SRS, and a PRACH transmission) for a plurality of time resource (e.g., symbols and/or slots) sets. The power control parameter sets contain, at least, one different parameter value, e.g., different open-loop parameters and/or different fractional pathloss compensation factor. In some implementations, the configuration message explicitly configures each power control parameter set. In some other implementations, the configuration message explicitly configures a first power control parameter set and the offset value of one or more parameters to be used when determining the one or more of second power control parameter sets.

FIG. 4 illustrates an example scenario 400 in accordance with aspects of the present disclosure. The scenario 400, for instance, illustrates fixed association between power control sets and slot types. The scenario 400 includes a power control parameter SBFD_Set 402, SBFD slots 404, a power control parameter NonSBFD_set 406, and non-SBFD slots 408. Further, a fixed association 410 is illustrated between the SBFD_Set 402 and the NonSBFD_set 406.

FIG. 5 illustrates an example signaling diagram 500 in accordance with aspects of the present disclosure. The signaling diagram includes a network node 502 (e.g., an NE 102 such as a gNB) and a UE 104, operations of the network node 502 and the UE 104, signaling by the network node 502, and data transmission by the UE 104. In the signaling diagram 500 at 504 the network node 502 configures two UL PC parameter sets: SBFD_Set for SBFD slots and nonSBFD_Set for non-SBFD slots considering, e.g., time-frequency resource allocations and/or expected SI and/or CLI levels; at 506 the network node 502 sends a UL PC parameter sets configuration message to the UE 104; at 508 the UE 102 determines using the SBFD_Set a first UL power for an UL transmission to be used during SBFD slots and determine using the nonSBFD_Set a second UL power for the UL transmission to be used during non-SBFD slots; at 510 the UE 104 performs an UL transmission during SBFD slots using the first UL power; and at 512 the UE 104 performs an UL transmission during non-SBFD slots using the second UL power.

In implementations such as illustrated in the scenario 400 and the signaling diagram 500, the UE is configured (e.g., receives a configuration message) with two power control parameter sets, where the set association and/or usage is implicitly indicated. For instance, the first set (e.g., SBFD_Set 402) is implicitly indicated to be used to determine the UL power, e.g., for a PUSCH transmission during SBFD time resources. The second set (e.g., nonSBFD_Set 406) is implicitly indicated to be used to determine the UL power, e.g., for the PUSCH transmission during non-SBFD time resources.

In at least some implementations, the SBFD slots and non-SBFD slots are determined from an explicit time-frequency configuration message. In some examples, the SBFD and non-SBFD time resources are explicitly indicated within the configuration message. In at least some implementations, the DL and UL SBs within the SBFD slots are completely non-overlapped. In some implementations, the DL and UL SBs within the SBFD slots are partially or completely overlapped. In such scenarios, the SBFD-based time resources type may be categorized into several types. In some implementations, the determined UL power using the set indicated for SBFD time resources is higher than the determined UL power using the set indicated for non-SBFD time resources, such as to compensate for expected high SI and CLI levels, and therefore improving the SINR of the received UL signal.

FIG. 6 illustrates an example scenario 600 in accordance with aspects of the present disclosure. The scenario 600, for instance, illustrates adaptive association between power control parameter sets and slot types, e.g., change in expected SI/CLI level in SBFD slots. The scenario 600 includes a power control parameter set 602, a power control parameter set 604, a slot type 606, a slot type 608, and SI RSs and MRs 610.

FIG. 7 illustrates an example signaling diagram 700 in accordance with aspects of the present disclosure. The signaling diagram 700 includes a network node 702 (e.g., an NE 102 such as a gNB) and a UE 104, operations of the network node 702 and the UE 104, signaling by the network node 702, and data transmission by the UE 104. In the signaling diagram 700: At 704 the network node 702 configures two UL PC parameter sets with their association with time resources, e.g., Set A associated with SBFD slots and Set B associated with non-SBFD slots considering, e.g., time-frequency resource allocations and/or expected SI and/or CLI levels; at 706 the network node 702 transmits a UL PC parameter sets configuration message to the UE 104; at 708 the UE 104 determines using Set A a first UL power for an UL transmission to be used during SBFD slots and determines using Set B a second UL power for the UL transmission to be used during non-SBFD slots; at 710 the UE 104 performs UL transmission during SBFD slots using the first UL power; at 712 the UE 104 performs an UL transmission during non-SBFD slots using the second UL power; at 714 the network node 702 determines to change the association of SBFD slots from Set A to Set B, e.g., due to change in the expected SI and/or CLI levels; at 716 the network node 702 transmits a SBFD slots set-reassociation message to the UE 104; at 718 the UE 104 redetermines the first UL power for an UL transmission to be used during SBFD slots using Set B; at 720 the UE 104 performs an UL transmission during SBFD slots using the first UL power; and at 722 the UE 104 performs an UL transmission during non-SBFD slots using the second UL power.

According to implementations a UE receives, from its serving network node (e.g., a serving gNB), a configuration message containing one or more of power control parameter sets and a set-association indicator indicating for which time resource indexes or time resource type (e.g., SBFD slots or non-SBFD slots) a set is to be used with. In at least some implementations each power control parameter set can be associated with one or more time-resource types, while each time-resource type can be associated with one power control parameter set, such as illustrated in the scenario 600. In some scenarios, the serving network may change a set association due to, e.g., change in expected SI and/or CLI levels in one or more slots or slot type.

In implementations such as illustrated in the scenario 600 and the signaling diagram 700, the UE 104 is configured with two power control parameter sets, power control parameter set 602 and power control parameter set 604, where each set is initially association with a different time resource type (e.g., SBFD or non-SBFD slots). For instance, the power control parameter set 602 is explicitly indicated to be associated during the slot type 606 (e.g., SBFD slots) and the power control parameter set 604 is explicitly indicated to be used during the slot type 608, e.g., SBFD slots. In some scenarios, the serving network may change a set-association due to, e.g., change in expected SI and/or CLI levels in one or more slots or slot type. The change in expected SI and/or CLI levels, for instance, may be due to, e.g., change of scheduled users' traffic, SI and/or CLI managing and/or handling technique, SI and/or CLI channel conditions, etc. In this case, the UE receives a set-reassociation message, e.g., via a downlink control information (DCI) or a radio resource control (RRC) message, changing the association of one or more of power control parameter sets. In some examples, the set-reassociation message indicates: the time-resource indexes (e.g., the slot indexes), and the first time-resource index and the number of time resources (e.g., x slots, starting from slot #n).

The new set association can be valid, after which the UE activities back the original/initial set association. In some implementations, the set-reassociation message indicates the first time-resource index (e.g., slot #n as the starting/first slot) without any duration or expiration indication. In another example, the set-reassociation message does not indicate time-resource indexes, and the UE assumes that the new association starts immediately, e.g., from next time resource of corresponding time resources.

FIG. 8 and FIG. 9 illustrate example scenarios 800 and 900 in accordance with aspects of the present disclosure. The scenarios 800, 900 include a power control parameter set 802, a power control parameter set 804, a slot type 806, a slot type 808, and SI RSs and SI MRs 810. The scenarios 800, 900, for instance, illustrate adaptive and fixed association between power control parameter sets 802, 804, slot types 806, 808, and SI RSs and SI MRs 810.

In implementations a FD-capable UE receives from its serving network node (e.g., a serving gNB) a configuration message containing one or more power control parameter sets, where each power control parameter set is associated (e.g., implicitly or explicitly) with one or more time resource indexes or time resource types (e.g., SBFD or non-SBFD slots), and one or more of SI reference signals (RSs) and SI measurement resources (SI MR). In some implementations, the one or more SI RSs and/or SI MRs are associated with one or more power control parameter sets, such as illustrated in the scenario 800. In some other implementations, the one or more of SI RSs and SI MRs are associated with one or more time resource indexes or time resource types, such as illustrated in the scenario 900. The SI RSs can be implemented as a SRS or an uplink demodulation RSs (UL DMRSs).

In implementations such as illustrated in the scenarios 800, 900, the FD-capable UE is configured (e.g., receives a configuration message) with two power control parameter sets, where the set association and/or usage is implicitly indicated and/or explicitly indicated. For instance, the power control parameter set 802 is implicitly/explicitly indicated to be used to determine the UL power, e.g., for a PUSCH transmission during SBFD time resources and the power control parameter set 804 is implicitly/explicitly indicated to be used to determine the UL power, e.g., for the PUSCH transmission during non-SBFD time resources.

In implementations during a SBFD slot and as part of the open loop UL power determination (e.g., for a PUSCH transmission) a FD-capable UE uses one or more of the associated SI RSs and SI MRs 810 to compute a first UL transmit power value corresponding to a SI level below a configured, indicated, and/or predefined value. Further, an FD-capable UE uses the associated power control parameter set to determine a second UL transmit power value. The FD-capable UE can use the first and the second UL transmit power values to determine a third UL transmit power, e.g., as the minimum between the first and second transmit powers. The FD-capable UE can use the determined third UL transmit power for the PUSCH transmission during the SBFD slots.
