FIELD

[0002] Various embodiments generally relate to the field of cellular communications, and particularly to uplink (UL) power control in a New Radio (NR) network.

BACKGROUND

[0003] Current Third Generation Partnership Project (3GPP) New Radio (NR) specifications (or 5G specifications) do not specifically address issues related to UL power control in situations where a UE may not be configured with a sounding reference signal (SRS) resource indicator (SRI) field in the scheduling downlink control information (DCI).

DETAILED DESCRIPTION

[0007] The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well- known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrase "A or B" means (A), (B), or (A and B).

[0008] NR systems will support coexistence of diverse services and traffic communication in a common carrier. As different services have different requirements and characteristics, multiplexing techniques need to be studied so that transmission of packets of each service type is minimally impacted. In particular, transmission of one service type needs to be made with higher end-to-end reliability than other coexisting transmissions of difference services. One way to protect the reliability of a critical transmission when overlap with other transmissions and/or unfavorable channel conditions are unavoidable is to boost the uplink (UL) transmit power. UL power control enhancements may help achieve better coexistence of different service types and target reliability of critical communications such as ultra-reliable low latency communications URLLC.

[0009] Disclosed embodiments address different UL power control enhancements for UL data channels.

[0010] Existing solutions for protecting the reliability of a critical transmission when overlap with other transmissions and/or unfavorable channel conditions are unavoidable include:

1. semi-static indication of open loop power control parameters;

2. dynamic implicit indication of open loop power control parameters and path-loss estimates in downlink control information (DCI), such as via mapping to a sounding reference signal (SRS) resource indicator (SRI) field;

B. closed loop transmit power control adjustment indicator in a field of the DCI; and/or

4. power control closed-loop process indication, via mapping to SRI field.

[0011] In the open loop power control, there is no feedback either from the UE to a Node B/base station, such as to a NR evolved Node B (gNodeB). In an open loop power control scenario, the UE typically estimates the power strength for an uplink transmission based on a signal received from the Node B. Based on this estimate, the mobile unit adjusts the transmit power accordingly.

[0012] In closed loop power control, feedback is used for adjusting the transmit power level. In particular, the Node B receives an UL signal from the UE, and, based on a determined power level of the signal, as well as other parameters such as signal to noise ratio (SNR) and bit error rate (BER), the Node B determines what is the optimum power level for UL transmission by the UE to achieve effective communication link performance. This estimated power level may be communicated to the UE by the Node B over a control channel. The UE then adjusts the power level accordingly using the feedback provided by the Node B for UL transmissions. The UE may also estimate the Node B's power level and communicate to the

Node B to adjust its power level to achieve effective reverse link performance.

[0013] As mentioned above, some of the power control parameter indications are made via mapping to an SRI field in DCI. However, SRI is a configurable field in DCI and not all UEs may have SRI field configured in the DCI or UL scheduling grant. Hence, for those UEs, other solutions are needed to indicate power control parameters.

[0014] Some embodiments disclosed herein provide the following solutions:

1. dynamic explicit indication of one or more open loop power control parameters and/or path loss estimates and/or closed-loop power control process in the DCI, in a UE specific or group-common manner;

2. radio network temporary identifier (RNTI)-based indication of one or more open loop power control parameters and/or path loss estimates and/or closed-loop power control process, either via a configured RNTI UE-specific DCI or via group- common DCI; or

3. indication of an offset to existing or indicated closed-loop power control

adjustment parameter

[0015] Disclosed embodiments complement existing approaches so that UL power control adjustments can be made in a flexible manner for different UE configurations.

[0016] Overview

[0017] Power control (PC) for UL data transmission physical uplink shared channel (PUSCH) may be given by equation (1): 10. log₁₀ (2^mM_KB) + A_TF + <5(/)} Eq. (l) where P_PUSCH ^iS the data channel transmit power, and P_c,Max denotes maximum allowed transmit power to ensure that this maximum allowed transmit power in a carrier is not exceeded. The expression P₀(j) + a(j). PL(q) corresponds to network configurable open loop power control adjustment, where P_Q(j ) can be simplified to be the target received power, a(j) accounts for fractional path loss compensation, and PL(q ) is an estimate of the

UL path loss. Here, j refers to one pair of { P₀, a } , and there can be multiple open loop parameter pairs configured for a UE. For example, different open loop parameter pairs (of target received power and fractional path loss compensation) can be used for different types of PUSCH transmissions, e.g., transmission with configured grant, scheduled transmission, random access message 3 (Msg. 3) transmission etc. q refers to selection of path loss estimate for UL transmission for a certain beamforming channel. The network may configure the device (UE) with a set of downlink reference signals, e.g., channel state information (CSI) reference signal (RS) (CSI-RS) or synchronization signal (SS) Block as references for path loss estimation, and each such reference signal may be associated with a value of q.

10. 1o ₁₀(2^mM_KB) accounts for the assigned bandwidth, i.e., power is proportional to the assigned bandwidth, m refers to sub-carrier spacing, M_RB is the number of resource blocks

(RBs) assigned, D_tr accounts for the modulation and coding scheme (MCS) used for PUSCH transmission, and <5(Z) refers to closed loop power adjustment transmit power control (TPC) command, where l points to one of multiple closed loop power control processes of the UE.

For example, a UE may have two independent closed-loop processes.

[0018] In the above equation, the network configures and/or indicates

P₀(j), a(j ) , PL(qr), <5(Z) parameters for a given UL data transmission.

[0019] In one of the existing approaches, the pair {P₀, a} , q, and l are indicated in an UL scheduling grant via a mapping to a field in the DCI, where the field is originally used to indicate UL sounding reference signal resource (SRI : SRS resource indicator). For example, there can be M=>1 set of pairs {P₀, a}, N=>1 path loss estimates, and P=>1 closed loop power control process , and each value indicated in SRI field in a DCI points to a pair of {P₀, a}, value of l and q.

[0020] Furthermore, in an existing approach, closed loop power control adjustment <5(Z) can be indicated in a field in a DCI. The value of l is either indicated via a separate bit-field such as in DCI format 2_2, or via mapping to an SRI field, in DCI format 0_1, as indicated above.

[0021] However, the SRI field in an UL scheduling grant is configurable, meaning that not all UEs may receive that field in the DCI, depending on whether they are configured or not. In NR, transmission of multiple services and application may coexist in a carrier and in certain scenarios. Hence, dynamic adjustment of power control parameters are desirable to ensure appropriate transmit power is used at devices, regardless of whether UE is configured to monitor SRI field in a DCI or not. For example, URLLC transmission may coexist with enhanced mobile broadband (eMBB) transmissions in a carrier, and if there is a chance one transmission may overlap with other, transmit power may be adjusted at one or more terminals in order to ensure interference is controlled and/or requirements are met for each service. As another example use case, when feasible, as an alternative to a longer PUSCH duration to ensure a low effective code rate, PUSCH transmissions may be scheduled with higher transmit power but shorter durations to achieve similar target reliability with lower latency.

[0022] Disclosed embodiments are directed to solutions to more flexibly indicate one or more of the power control parameters listed above. In the following examples/embodiments,

DCI refers to either UL scheduling grant in a PDCCH or group common DCI in a PDCCH. Each of these PDCCHs may have one or more UE specific fields where one or more of the above power control parameters can be indicated.

[0023] Note that different combinations of elements disclosed in the instant description may be straightforwardly defined to realize different trade-offs between scheduling flexibility and signaling overhead.

[0024] Indication of power control parameters in UL scheduling grant

[0025] In one embodiment, a pair of open loop PC parameters {P_Q, a} may be explicitly indicated in a field in a DCI. For example, a UE may be configured with M >1 pairs, and a field in DCI may indicate one of the pairs. The M pairs may be configured to a UE by higher layer signaling, such as radio resource control (RRC) signaling. It should be understood that one pair is different from the other if at least one element in the pair is different in the pairs. For example, it may be possible that two pairs have same a but different P₀.

[0026] In another embodiment, a path loss estimate process, i.e., q may be explicitly indicated in a field in DCI. For example, a UE can be configured with N> 1 values of q, each indicating path loss estimate for a specific beamforming channel, i.e., beam pair. The value of q may also point to certain downlink reference signals to be assumed for path loss estimate calculation. One of multiple values of q configured for a UE can be indicated in the field. A set of values of q with corresponding mapping to a beam and/or DL reference signal may be configured to a UE by higher layer signaling, such as RRC.

[0027] In another embodiment, a value of closed loop process indicator / may be indicated in a field in DCI. A UE may be configured with P ³ 1 closed loop power control process, and each may have a certain range of power control step adjustment <5, e.g., {-1, 0, 1, 3} dB which can be indicated in the same field or in a different field in the DCI. P may be configured to the UE by higher layers including RRC.

[0028] In another embodiment, where there are more than one closed loop power control processes configured to a UE, a second closed loop power control process may be defined with step-sizes different from those for the first process. Specifically, in an example, the step adjustment values can be different from {-1, 0, 1, 3} dB, and specified to cover a larger dynamic range, or be defined with one or more offsets that may be added to the existing step-down and step-up values respectively, while still including the 0 dB step-size.

[0029] As a further extension of the above embodiment, the second closed loop power control process may be configured as a non-accumulative process while the first process is indicated as an accumulative process, or vice-versa. Here, by non-accumulative process, what is meant is a scenario where an indicated d or adjustment value is not added to the previous value of d for a given process, but rather applied as an absolute value just for the

indicated/scheduled transmissions. By accumulative process, what is meant is a scenario where an indicated d or adjustment value is added to the previous value of d for a given process.

[0030] In another embodiment, one or more of the parameters pair {P₀, a} , q, and l, are indicated by RRC and the rest is indicated explicitly in one or more fields in a DCI.

[0031] In yet another embodiment, a UE may be configured with a table with Q>1

configurations, where each configuration points to a set of one or more of parameter pairs {P₀, a} , along with q, and 1. One configuration index may be explicitly indicated in a DCI field. If one or more parameters are not indicated via a configuration index, those parameters can be configured by higher layers or indicated in DCI in a separate field.

[0032] In another embodiment, a certain range of MCS may be associated with one or more of pairs {P₀, a} , along with q, and 1. According to this embodiment, if the MCS indicated is above a certain index, one or more of the parameters pair {P₀, a} , q, and l may be implicitly obtained.

[0033] In still another embodiment, one or more of the parameter pairs {P₀, a} , along with q, and l, can be implicitly associated with one or more of the following fields in the DCI:

• bandwidth (BW) part or numerology;

• precoder information or number of layers; • carrier indicator;

• UL or supplementary UL (SUL) indicator

• time/frequency domain resource assignments or resource allocation types - for this option, specifically, the UE may be configured by higher layers to use a second set of power control parameters when the scheduled PUSCH duration is shorter than or equal to a specified or higher layer configured threshold, e.g., 2 or 4 symbols - as another example, the threshold, in number of symbols, may be defined on per subcarrier basis;

• frequency hopping flag; or

• antenna ports.

[0034] Associating RNTI of DCI with PC parameters

[0035] Although doing so would provide the most flexibility, explicitly indicating the parameter pairs {P_Q, a} , along with q, and l in a DCI field may increase DCI transmission overhead. Hence, at the expense of some flexibility loss, an alternative embodiment may include associating one or more of the parameter set, pair {P_Q, a} , along with q, and l, with the RNTI used for transmission of the DCI, where the RNTI can be UE-specific or group-specific and configured by higher layer signaling. For example, if RNTI A is used, the UE may assume one set of parameters, whereas if RNTI B is used UE may assume another set of PC

parameters. The parameters that are not associated with RNTI may be configured by a higher layers and/or implicitly (such as by mapping to another field) or explicitly indicated in the DCI in one or more fields.

[0036] In one embodiment, pair {P₀, a} may be configured by higher layers, q may be indicated in a field in DCI, and closed-loop power control process I may be obtained based on RNTI used for transmission.

[0037] In another example, pair {P₀, a} is higher layer configured, q can be indicated in a field in DCI or follow semi-static configuration, and closed-loop power control process I can be obtained based on RNTI used for transmission. Further, without loss of generality, the UE may be configured to use process I =1 for PUSCH transmissions scheduled using scheduling DCI scrambled with RNTI X (a new RNTI configured by higher layers), and a default process I =1 for PUSCH transmissions scheduled using scheduling DCI scrambled with other RNTIs (e.g., cell- RNTI (C-RNTI), MCS-C-RNTI, etc.). [0038] In another embodiment, an existing RNTI such as MCS-C-RNTI may be additionally used to indicate one or more of the configurable power control parameters.

[0039] Indication of an offset to closed-loop power control adjustment

[0040] In some cases, the configured range for step size d may not be adequate, such as in instances where transmission of one service type overlaps with another service type with different requirements.

[0041] In one embodiment, PUSCH transmit power may be adjusted by applying an offset to the step adjustment indicated in the DCI, such as set forth in equation (2) below:

Ppusc_H = n{Pc_,Max_> Po(j + «(j - PL(.q + 10. log₁₀ (2^M_rb) + A_TF + d(1 ) + offset } Eq. (2)

[0042] where "offset" may, according to an embodiment, be indicated by the network, either by higher layer signaling or dynamically in DCI either implicitly or explicitly, to adjust power. One or more other configurable PC parameters {P₀, a} , q, and l, may, according to an embodiment, be indicated by higher layer and/or one or more fields in DCI, explicitly or implicitly. For example, the absolute step size used in the equation above may not exceed 4dB. If this is not sufficient in some cases, the network may leverage using the offset to bring the step size to a desired value.

[0043] In one embodiment, a UE may be configured to monitor a group-common DCI with a certain configured RNTI, where one or more bits may indicate one or more of offset, closed loop power control process l and step size <5(Z).

[0044] In another example, a RNTI of a UE-specific DCI such as UL grant or group common DCI in PDCCH may implicitly indicate an offset to be used with the TPC command <5(Z) indicated in other field in the DCI. The value of offset can be higher layer configured.

[0045] In yet another example, the offset can be UE specific and common for all the closed loop PC process, or specific to each PC loop process. In another example, offset can be common in a carrier.

[0046] Fig. 1 illustrates a process 100 according to embodiment. Process 100 includes, at operation 102, decoding a downlink control information (DCI) from a NR evolved Node B (gNodeB), the DCI including an indication regarding a selection of one of a first open-loop power control parameters set and a second open-loop power control parameters set, the indication corresponding to an UL transmission by the UE, wherein each of the first open-loop power control parameters set and the second open loop power control parameters set comprises a respective { P₀ , a}, wherein P₀ corresponds to a target received power at the gNodeB for the UL transmission, and a corresponds to fractional path loss compensation for the UL transmission; at operation 104, selecting, based on the indication, one of the first open-loop power control parameters set and the second open-loop power control parameters set; and at operation 106, encoding the UL transmission for transmission to the gNodeB, wherein a transmit power of the UL transmission is based on said one of the first open-loop power control parameters set and the second open-loop power control parameters set.

[0047] Fig. 2 illustrates an example architecture of a system 200 of a network, in accordance with various embodiments. The following description is provided for an example system 200 that operates in conjunction with the LTE system standards and 5G or NR system standards as provided by 3GPP technical specifications. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems (e.g., Sixth

Generation (6G)) systems, IEEE 802.16 protocols (e.g., WMAN, WiMAX, etc.), or the like.

[0048] As shown by Figure 2, the system 200 includes UE 201a and UE 201b (collectively referred to as "UEs 201" or "UE 201"). In this example, UEs 201 are illustrated as

smartphones, but may also comprise any mobile or non-mobile computing device.

[0049] The UEs 201 may be configured to connect, for example, communicatively couple, with an or RAN 210. In embodiments, the RAN 210 may be an NG RAN or a 5G RAN, an E- UTRAN, or a legacy RAN, such as a UTRAN or GERAN. As used herein, the term "NG RAN" or the like may refer to a RAN 210 that operates in an NR or 5G system 200, and the term "E- UTRAN" or the like may refer to a RAN 210 that operates in an LTE or 4G system 200. The UEs 201 utilize connections (or channels) 203 and 204, respectively, each of which comprises a physical communications interface or layer (discussed in further detail below).

[0050] In this example, the connections 203 and 204 are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a GSM protocol, a CDMA network protocol, a PTT protocol, a POC protocol, a UMTS protocol, a 3GPP LTE protocol, a 5G protocol, a NR protocol, and/or any of the other communications protocols discussed herein. In embodiments, the UEs 201 may directly exchange communication data via a ProSe interface 205. The ProSe interface 205 may alternatively be referred to as a SL interface 205 and may comprise one or more logical channels, including but not limited to a PSCCH, a PSSCH, a PSDCH, and a PSBCH.

[0051] The UE 201b is shown to be configured to access an AP 206 (also referred to as "WLAN node 206," "WLAN 206," "WLAN Termination 206," "WT 206" or the like) via connection 207.

The connection 207 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.11 protocol, wherein the AP 206 would comprise a wireless fidelity (Wi-Fi^®) router. In this example, the AP 206 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below).

[0052] The RAN 210 can include one or more AN nodes or RAN nodes 211a and 211b

(collectively referred to as "RAN nodes 211" or "RAN node 211") that enable the connections

203 and 204. As used herein, the terms "access node," "access point," or the like may describe equipment that provides the radio baseband functions for data and/or voice connectivity between a network and one or more users. These access nodes can be referred to as BS, NR evolved NodeBs (gNodeBs), RAN nodes, eNBs, NodeBs, RSUs, TRxPs or TRPs, and so forth. As used herein, the term "NG RAN node" or the like may refer to a RAN node 211 that operates in an NR or 5G system 200 (for example, a gNB), and the term "E-UTRAN node" or the like may refer to a RAN node 211 that operates in an LTE or 4G system 200 (e.g., an eNB). According to various embodiments, the RAN nodes 211 may be implemented as one or more of a dedicated physical device such as a macrocell base station, and/or a low power (LP) base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.

[0053] In embodiments, the UEs 201 can be configured to communicate using OFDM communication signals with each other or with any of the RAN nodes 211 over a multicarrier communication channel in accordance with various communication techniques, such as, but not limited to, an OFDMA communication technique (e.g., for downlink communications) or a

SC-FDMA communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

[0054] In some embodiments, a downlink resource grid can be used for downlink

transmissions from any of the RAN nodes 211 to the UEs 201, while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot.

Such a time-frequency plane representation is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are several different physical downlink channels that are conveyed using such resource blocks.

[0055] According to various embodiments, the UEs 201 and the RAN nodes 211, 212 communicate data (for example, transmit and receive) data over a licensed medium (also referred to as the "licensed spectrum" and/or the "licensed band") and an unlicensed shared medium (also referred to as the "unlicensed spectrum" and/or the "unlicensed band"). The licensed spectrum may include channels that operate in the frequency range of

approximately 400 MHz to approximately 3.8 GHz, whereas the unlicensed spectrum may include the 5 GHz band.

[0056] The RAN nodes 211 may be configured to communicate with one another via interface 212. In embodiments where the system 200 is a 5G or NR system, the interface 212 may be an Xn interface 212. The Xn interface is defined between two or more RAN nodes 211 (e.g., two or more gNodeBs or gNBs and the like) that connect to 5GC 220, between a RAN node 211 (e.g., a gNB) connecting to 5GC 220 and an eNB, and/or between two eNBs connecting to 5GC 220.

[0057] The RAN 210 is shown to be communicatively coupled to a core network— in this embodiment, core network (CN) 220. The CN 220 may comprise a plurality of network elements 222, which are configured to offer various data and telecommunications services to customers/subscribers (e.g., users of UEs 201) who are connected to the CN 220 via the RAN 210. The components of the CN 220 may be implemented in one physical node or separate physical nodes including components to read and execute instructions from a machine- readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium). [0058] Generally, the application server 230 may be an element offering applications that use

IP bearer resources with the core network (e.g., UMTS PS domain, LTE PS data services, etc.).

The application server 230 can also be configured to support one or more communication services (e.g., VoIP sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UEs 201 via the EPC 220.

[0059] In embodiments, the CN 220 may be a 5GC (referred to as "5GC 220" or the like), and the RAN 210 may be connected with the CN 220 via an NG interface 213. In embodiments, the NG interface 213 may be split into two parts, an NG user plane (NG-U) interface 214, which carries traffic data between the RAN nodes 211 and a UPF, and the SI control plane (NG-C) interface 215, which is a signaling interface between the RAN nodes 211 and AMFs.

[0060] In embodiments, the CN 220 may be a 5G CN (referred to as "5GC 220" or the like), while in other embodiments, the CN 220 may be an EPC). Where CN 220 is an EPC (referred to as "EPC 220" or the like), the RAN 210 may be connected with the CN 220 via an SI interface 213. In embodiments, the SI interface 213 may be split into two parts, an SI user plane (Sl-U) interface 214, which carries traffic data between the RAN nodes 211 and the S- GW, and the Sl-MME interface 215, which is a signaling interface between the RAN nodes 211 and MMEs.

[0061] Fig. 3 illustrates example components of baseband circuitry 310 and radio front end modules (RFEM) 315 in accordance with various embodiments. Baseband circuitry 310 includes a RF interface 318 connecting it to the RFEM. As shown, the RFEMs 315 may include Radio Frequency (RF) circuitry 306, front-end module (FEM) circuitry 308, antenna array 311 coupled together at least as shown.

[0062] The baseband circuitry 310 includes circuitry and/or control logic configured to carry out various radio/network protocol and radio control functions that enable communication with one or more radio networks via the RF circuitry 306. The radio control functions may include, but are not limited to, signal modulation/demodulation, encoding/decoding, radio frequency shifting, etc. In some embodiments, modulation/demodulation circuitry of the baseband circuitry 310 may include Fast-Fourier Transform (FFT), precoding, or constellation mapping/demapping functionality. In some embodiments, encoding/decoding circuitry of the baseband circuitry 310 may include convolution, tail-biting convolution, turbo, Viterbi, or Low Density Parity Check (LDPC) encoder/decoder functionality. Embodiments of

modulation/demodulation and encoder/decoder functionality are not limited to these examples and may include other suitable functionality in other embodiments. The baseband circuitry BIO is configured to process baseband signals received from a receive signal path of the RF circuitry 306 and to generate baseband signals for a transmit signal path of the RF circuitry 306. The baseband circuitry 310 is configured to interface with an application circuitry for generation and processing of the baseband signals and for controlling operations of the RF circuitry 306. The baseband circuitry 310 may handle various radio control functions.
