Description

Technical Field

[0001] This application relates in general to wireless communication systems, including wireless communication systems that implement simultaneous PUSCH transmission based on a single DCI. Background Technology

[0002] Wireless mobile communication technologies use various standards and protocols to transmit data between base stations and wireless communication devices. For example, wireless communication system standards and protocols may include, for instance, 3GPP Long Term Evolution (LTE) (e.g., 4G), 3GPP New Radio (NR) (e.g., 5G), and the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for Wireless Local Area Networks (WLANs) (often referred to as Wi-Fi within the industry organization). ® ).

[0003] As envisioned by 3GPP, different wireless communication system standards and protocols can use various radio access networks (RANs) for communication between RAN base stations (sometimes also commonly referred to as RAN nodes, network nodes, or simply nodes) and wireless communication equipment called user equipment (UEs). 3GPP RANs can include, for example, Global System for Mobile Communications (GSM), Enhanced Data Rate GSM Evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and / or Next Generation Radio Access Network (NG-RAN).

[0004] Each RAN can use one or more Radio Access Technologies (RATs) to perform communication between the base station and the UE. For example, GERAN implements the GSM and / or EDGE RAT, UTRAN implements the Universal Mobile Telecommunications System (UMTS) RAT or other 3GPP RATs, E-UTRAN implements the LTE RAT (sometimes simply referred to as LTE), and NG-RAN implements the NR RAT (this NR RAT is sometimes referred to herein as the 5G RAT, 5G NR RAT, or simply NR). In some deployments, E-UTRAN may also implement the NR RAT. In some deployments, NG-RAN may also implement the LTE RAT.

[0005] The base stations used by a RAN can correspond to that RAN. An example of an E-UTRAN base station is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (also commonly referred to as Evolved Node B, Enhanced Node B, eNodeB, or eNB). An example of an NG-RAN base station is a Next Generation Node B (sometimes also called gNodeB or gNB).

[0006] The RAN provides communication services to external entities through its connection with the core network (CN). For example, E-UTRAN can utilize the evolved packet core (EPC), while NG-RAN can utilize the 5G core network (5GC).

[0007] 5G NR frequency bands can be divided into two or more distinct frequency ranges. For example, Frequency Range 1 (FR1) may include bands operating at frequencies below 6 GHz, some of which are available for previous standards and can potentially be extended to cover new spectrum offerings from 410 MHz to 7125 MHz. Frequency Range 2 (FR2) may include bands from 24.25 GHz to 52.6 GHz. It should be noted that in some systems, FR2 may also include bands from 52.6 GHz to 71 GHz (or higher). Bands in the millimeter-wave (mmWave) range of FR2 may have smaller coverage areas but potentially higher available bandwidth than bands in FR1. Those skilled in the art will recognize that these frequency ranges, presented by way of example, may change over time or in different regions. Attached Figure Description

[0017] Figure 9 A system for performing signaling between a wireless device and a network device according to an embodiment disclosed herein is illustrated. Detailed Implementation

[0018] Various implementations are described with respect to the UE. However, references to the UE are provided for illustrative purposes only. The example implementations can be used with any electronic component capable of establishing a connection to a network and configured with hardware, software, and / or firmware for exchanging information and data with the network. Therefore, the UE as described herein is used to represent any suitable electronic component.

[0019] In some wireless communication systems, for Sounding Reference Signal (SRS) power control, a set of power control parameters is configured in the SRS-ResourceSet information element (IE). This set of power control parameters may include, for example: an α parameter for partial and / or full path loss compensation; a P0 parameter providing the target received (Rx) power at the base station's receiver; and / or a pathlossReferenceRS parameter identifying the reference signal used for path loss estimation. Furthermore, in such cases, the closed-loop power control transmit power control (TPC) command may be indicated by downlink control information (DCI) (e.g., DCI format 2_3 in some wireless communication systems).

[0020] Furthermore, in some wireless communication systems, the Physical Uplink Shared Channel (PUSCH) power control information is indicated by the SRS Resource Indicator (SRI). The SRI can be provided to the UE in the "SRS Resource Indicator" field of the DCI.

[0021] The UE may be individually (e.g., previously) configured with a PUSCH-PowerControl IE having one or more SRI-PUSCH-PowerControl IEs listed therein, wherein each SRI-PUSCH-PowerControl IE is mapped to a possible SRI identified in the SRIs available in the DCI. The SRI-PUSCH-PowerControl IE may include, for example: an α parameter for partial and / or full path loss compensation; a P0 parameter providing the target Rx power at the base station's receiver; a pathlossReferenceRS parameter identifying the reference signal used for path loss estimation; and / or a ClosedLoopIndex index (e.g., 0 or 1) identifying the closed-loop transmit power factor stored in the UE's memory for closed-loop power control. Furthermore, in such cases, the closed-loop power control TPC command may be indicated by the DCI (e.g., in some wireless communication systems, the DCI format is 0_1, 0_2, or 2_2).

[0022] A list of one or more SRI-PUSCH-PowerControl IEs is an example of a "SRI-indexed list of power controls" as discussed in this article.

[0023] It has been determined that at least some wireless communication systems can benefit from supporting and using simultaneous PUSCH transmission based on a single DCI, where the single DCI schedules the UE's use of multiple (e.g., two) simultaneous PUSCH transmissions. In some cases, such simultaneous PUSCH transmission based on a single DCI can be transmitted by the UE according to spatial division multiplexing (SDM). For example, this could correspond to one of several advantageous schemes for simultaneous transmission across multiple panels (STxMP) PUSCH transmission in multi-transmitter-receiver point (TRP) (mTRP) systems based on a single DCI in some wireless communication systems (where such schemes could include SDM-based transmission schemes, such as single-frequency network (SFN) based transmission schemes supported in addition to SDM-based transmission schemes, etc.).

[0024] It is possible that the UE uses multiple antenna panels when performing simultaneous PUSCH transmissions. In some cases, each antenna panel in the antenna panel transmits one PUSCH transmission in the simultaneous PUSCH transmission. For example, it is possible that the UE's first antenna panel is used to transmit the first PUSCH transmission in two simultaneous PUSCH transmissions, while the UE's second antenna panel is used to transmit the second PUSCH transmission in two simultaneous PUSCH transmissions.

[0025] It will be understood that different antenna panels of the UE may exhibit different physical channel / path loss on their respective physical channels (e.g., due to channel differences, which may arise from different locations and / or orientations of the UE on / within / about the UE for each antenna panel, from the use of directional communication with different TRPs at each antenna panel, from the use of different power levels at each antenna panel, etc.). To address such differences between multiple antenna panels of the UE, it may be beneficial to implement one or more power control enhancements at the UE that operate on a daily antenna panel basis.

[0026] This paper proposes power control enhancements for simultaneous PUSCH transmission contexts based on a single DCI. First, open-loop power control (OLPC) enhancements for PUSCH power control in simultaneous PUSCH transmission contexts based on a single DCI are discussed. Then, closed-loop power control (CLPC) enhancements for PUSCH power control in simultaneous PUSCH transmission contexts based on a single DCI are discussed. Finally, PUSCH power scaling enhancements for simultaneous PUSCH transmission contexts based on a single DCI are discussed.

[0027] OLPC PUSCH Power Control Enhancement

[0028] The OLPC PUSCH implementation scheme described in this paper may involve determining the open-loop transmit power factor used by the UE when determining the transmit power to be used for the corresponding PUSCH.

[0029] In the first option for configuring applicable OLPC PUSCH power control for simultaneous PUSCH transmission based on a single DCI, a single PUSCH-PowerControlIE may exist within the PUSCH-Config IE configured by the network at the UE. Within the PUSCH-PowerControl IE, a single list of one or more SRI-PUSCH-PowerControl IEs may exist (e.g., a power control list with a single SRI index). Under the first option, the UE may apply the same list of one or more SRI-PUSCH-PowerControl IEs for transmissions on each of the two antenna panels.

[0030] Regarding each PUSCH transmission in simultaneous PUSCH transmission, the process may include, for example: applying a first SRI for a first antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a list of one or more SRI-PUSCH-PowerControlIEs to determine a first open-loop transmission power factor for the first PUSCH on the first antenna panel; and applying a second SRI for a second antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a list of one or more SRI-PUSCH-PowerControlIEs to determine a second open-loop transmission power factor for the second PUSCH on the second antenna panel. It should be noted that in some cases, the first SRI for the first antenna panel and the second SRI for the second antenna panel from the DCI may be the same SRI given in the DCI, while in other cases, these may be two separate SRIs, each provided in the DCI for a separate antenna panel.

[0031] In the second option for configuring applicable OLPC PUSCH power control for simultaneous PUSCH transmission based on a single DCI, a single PUSCH-PowerControlIE may exist within the PUSCH-Config IE configured by the network at the UE. Within the PUSCH-PowerControl IE, multiple lists of one or more SRI-PUSCH-PowerControl IEs may exist (e.g., power control lists of multiple SRI indices). Under the second option, the UE may apply a first list of one or more SRI-PUSCH-PowerControl IEs for transmission on the first antenna panel and a second list of one or more SRI-PUSCH-PowerControl IEs for transmission on the second antenna panel.

[0032] Regarding each PUSCH transmission in simultaneous PUSCH transmission, the process may include, for example: applying a first SRI for a first antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a list of one or more SRI-PUSCH-PowerControlIEs to determine a first open-loop transmission power factor for the first PUSCH on the first antenna panel; and applying a second SRI for a second antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a (second) list of one or more SRI-PUSCH-PowerControlIEs to determine a second open-loop transmission power factor for the second PUSCH on the second antenna panel. It should be noted that in some cases, the first SRI for the first antenna panel and the second SRI for the second antenna panel from the DCI may be the same SRI given in the DCI, while in other cases, these may be two separate SRIs, each provided in the DCI for a separate antenna panel.

[0033] In the third option for configuring applicable OLPC PUSCH power control for simultaneous PUSCH transmission based on a single DCI, two PUSCH-PowerControlIEs may exist in the PUSCH-Config IE configured by the network at the UE. Within each of the two PUSCH-PowerControl IEs, a list of one or more SRI-PUSCH-PowerControl IEs may exist (e.g., a power control list with SRI indices can be found in each PUSCH-PowerControl IE). Under the third option, the UE may apply a first list of one or more SRI-PUSCH-PowerControl IEs transmitted from the first PUSCH-PowerControl IE on the first antenna panel and a second list of one or more SRI-PUSCH-PowerControl IEs transmitted from the second PUSCH-PowerControl IE on the second antenna panel.

[0034] Regarding each PUSCH transmission in simultaneous PUSCH transmission, the process may include, for example: applying a first SRI for a first antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a first list of one or more SRI-PUSCH-PowerControl IEs from a first PUSCH-PowerControl IE to determine a first open-loop transmission power factor for the first PUSCH on the first antenna panel; and applying a second SRI for a second antenna panel from the DCI scheduling simultaneous PUSCH transmissions together with a second list of one or more SRI-PUSCH-PowerControl IEs from a second PUSCH-PowerControl IE to determine a second open-loop transmission power factor for the second PUSCH on the second antenna panel. It should be noted that in some cases, the first SRI for the first antenna panel and the second SRI for the second antenna panel from the DCI may be the same SRI given in the DCI, while in other cases, these may be two separate SRIs, each provided in the DCI for a separate antenna panel.

[0035] When OLPC is used for simultaneous PUSCH transmission based on a single DCI, the single DCI (which may be, for example, format 0_1 ​​and / or 0_2) may provide one or more SRIs in one or more SRI fields. In some cases, a single SRI field providing a single SRI may exist in the DCI. In such cases, the same SRI may be applied to one or more lists of one or more SRI-PUSCH-PowerControl IEs (e.g., power control lists of one or more SRI indices) corresponding to the first antenna panel and / or the second antenna panel. It should be noted that in some such cases, a single such list of SRI-PUSCH-PowerControl IEs may exist, which is used with respect to each antenna panel in the antenna panel to determine the open-loop transmit power factor for each PUSCH on each antenna panel; while in other such cases, two separate such lists of SRI-PUSCH-PowerControl IEs may exist, each list being used with respect to a separate antenna panel to determine the open-loop transmit power factor for the PUSCH on that antenna panel.

[0036] In other cases, two SRIs may exist in two SRI fields of a single DCI. In such cases, the first SRI may be directed to one or more lists of SRI-PUSCH-PowerControl IEs (e.g., power control lists indexed by SRI) corresponding to the first antenna panel, while the second SRI may be directed to a list of SRI-PUSCH-PowerControl IEs (e.g., power control lists indexed by SRI) corresponding to the second antenna panel. It should be noted that in some such cases, a single list of SRI-PUSCH-PowerControl IEs may exist, used with respect to each antenna panel to determine the open-loop transmit power factor for each PUSCH on each antenna panel; while in other such cases, two separate lists of SRI-PUSCH-PowerControl IEs may exist, each list used with respect to a separate antenna panel to determine the open-loop transmit power factor for the PUSCH on that antenna panel.

[0037] In wireless communication systems configured for simultaneous PUSCH transmission based on a single DCI, various specific implementations exist when the single DCI (which may be, for example, format 0_1 ​​and / or 0_2) includes two SRI fields (each SRI field having an independent SRI), in the case of using Dynamic Point Selection (DPS), where the network schedules the UE to transmit PUSCH from only one antenna panel.

[0038] In the first option, the SRI corresponding to the scheduled antenna panel (i.e., the antenna panel used for scheduling) in a single DCI can be used, while another SRI is reserved. For example, if a single DCI schedules the UE to transmit PUSCH from a first antenna panel, the first SRI for the first antenna panel (e.g., based on the order of the two SRIs in the DCI) can be applied to a list of one or more SRI-PUSCH-PowerControl IEs for the first antenna panel to determine the open-loop transmit power factor for PUSCH. Conversely, if a single DCI schedules the UE to transmit PUSCH from a second antenna panel, the second SRI for the second antenna panel (e.g., based on the order of the two SRIs in the single DCI) can be applied to a list of one or more SRI-PUSCH-PowerControl IEs for the second antenna panel to determine the open-loop transmit power factor for PUSCH.

[0039] In the second option, a first sorted SRI (based on the sorting of two SRIs in the DCI) is used in each case, and a second sorted SRI (based on the sorting of two SRIs in the DCI) is retained. For example, if a single DCI schedules the UE to transmit PUSCH from the first antenna panel, the first sorted SRI (based on the sorting of two SRIs in the DCI) can be applied to a list of one or more SRI-PUSCH-PowerControl IEs for the first antenna panel to determine the open-loop transmit power factor for PUSCH. Conversely, if a single DCI schedules the UE to transmit PUSCH from the second antenna panel, the first sorted SRI (based on the sorting of two SRIs in the single DCI) can be applied to a list of one or more SRI-PUSCH-PowerControl IEs for the second antenna panel to determine the open-loop transmit power factor for PUSCH.

[0040] It should be noted that under either option, the two antenna panels can be mapped to different SRS-ResourceSets or different SRS-Resources. In other words, it is possible that the SRI used with the first antenna panel in the DCI can be indexed into a first SRS-ResourceSet for the first antenna panel, and / or the SRI used with the second antenna panel in the DCI can be indexed into a second SRS-ResourceSet for the second antenna panel. Alternatively, the SRI used with the first antenna panel in the DCI can be indexed into a first set of SRS-Resources in a (single) SRS-ResourceSet for the first antenna panel, and / or the SRI used with the second antenna panel in the DCI can be indexed into a second set of SRS-Resources in a (single) SRS-ResourceSet for the second antenna panel.

[0041] In some wireless communication systems using OLPC for simultaneous PUSCH transmission based on a single DCI, it is possible that the system is configured such that each PUSCH in the simultaneous PUSCH is transmitted according to the same open-loop transmit power factor. In such systems, a first SRI / list of one or more SRI-PUSCH-PowerControl IE pairs can be used to determine a first open-loop transmit power factor P0, while a second SRI / list of one or more SRI-PUSCH-PowerControl IE pairs can be used to determine a second open-loop transmit power factor P1 (e.g., in a manner described elsewhere herein). Then, in a first option, the open-loop transmit power factor for each PUSCH in the simultaneous PUSCH is determined as max{P0, P1}. In a second option, the open-loop transmit power factor for each PUSCH in the simultaneous PUSCH is determined as min{P0, P1}.

[0042] In other cases, each PUSCH in a PUSCH may be transmitted simultaneously according to a separate open-loop transmit power factor P0, P1 determined individually with respect to one or more SRI-PUSCH-PowerControl IE pairs corresponding to the antenna panel used for that PUSCH. This results in, for example, a first PUSCH being transmitted according to a first open-loop transmit power factor P0, and a second PUSCH being transmitted according to a second open-loop transmit power factor P1, where P0 and P1 may (or may not) be different values.

[0043] CLPC PUSCH Power Control Enhancement

[0044] The CLPC PUSCH implementation scheme described in this paper may involve determining the closed-loop transmit power factor used by the UE when determining the transmit power to be used for the corresponding PUSCH.

[0045] In an implementation for configuring CLPC PUSCH power control for simultaneous PUSCHs based on a single DCI on corresponding antenna panels, it is possible to configure / indicate two simultaneously transmitted PUSCHs with respect to different closed-loop indices (e.g., one PUSCH corresponds to index "0" and the other PUSCH corresponds to index "1"). These closed-loop indices may correspond respectively to a first stored closed-loop transmit power factor for a first antenna panel of the UE and a second stored closed-loop transmit power factor for a second antenna panel of the UE.

[0046] For CLPC, when the UE operates in accumulator mode, the first stored closed-loop transmit power factor and / or the second stored closed-loop transmit power factor are updated based on the incoming TPC according to the accumulator mode. When the UE operates outside of accumulator mode, the first stored closed-loop transmit power factor and / or the second stored closed-loop transmit power factor are replaced based on the incoming TPC according to the non-accumulator mode.

[0047] When CLPC is used for simultaneous PUSCH transmission based on a single DCI, the DCI (which can be, for example, format 0_1, 0_2, or 2_2) can provide one or more TPC commands in one or more TPC fields. It should be noted that in some cases, a DCI with one or more TPC commands can be a (single) DCI that schedules simultaneous PUSCH. In other cases, a DCI with one or more TPC commands can be a different (e.g., a later) DCI compared to the DCI that schedules simultaneous PUSCH.

[0048] In some cases, a single TPC field may exist in the DCI that provides a single TPC command. In such cases, the same TPC command may be applied (e.g., for updating or replacing) each of the first and second stored closed-loop transmit power factors at the UE.

[0049] In other cases, the DCI may include multiple TPC fields, each providing an independent TPC command. In such cases, a first TPC command may be applied (e.g., for updating or replacing) a first stored closed-loop transmit power factor at the UE, and a second TPC command may be applied (e.g., for updating or replacing) a second stored closed-loop transmit power factor at the UE.

[0050] It should be noted that the first antenna panel may be associated with an SRI in a first list of one or more SRI-PUSCH-PowerControl IEs for the first antenna panel, and the second antenna panel may be associated with an SRI in a list of one or more SRI-PUSCH-PowerControl IEs for the second antenna panel (e.g., in a manner described elsewhere in this document).

[0051] In wireless communication systems configured for simultaneous PUSCH transmission based on a single DCI, various specific implementations exist when using DPS, where the network schedules the UE to transmit PUSCH from only one antenna panel, when the DCI (which may be, for example, format 0_1 ​​and / or 0_2) includes two TPC fields (each TPC field having an independent TPC command).

[0052] In the first option, the TPC command in the DCI corresponding to the scheduled antenna panel (i.e., the antenna panel for which scheduling is performed) can be used, and another TPC is reserved. For example, if the DCI schedules the UE to transmit PUSCH from the first antenna panel, the first TPC command for the first antenna panel (e.g., based on the order of the two TPC commands in the DCI) can be applied (e.g., for updating or replacing) the first stored closed-loop transmit power factor at the UE corresponding to the first antenna panel. Conversely, if the DCI schedules the UE to transmit PUSCH from the second antenna panel, the second TPC command for the second antenna panel (e.g., based on the order of the two TPC commands in the DCI) can be applied (e.g., for updating or replacing) the second stored closed-loop transmit power factor at the UE corresponding to the second antenna panel.

[0053] In the second option, a first sorting TPC command in the DCI (based on the sorting of the two TPC commands in the DCI) is used in each case, and a second sorting TPC command (based on the sorting of the two TPC commands in the DCI) is retained. For example, if the DCI schedules the UE to transmit PUSCH from the first antenna panel, the first sorting TPC command (based on the sorting of the two TPC commands in the DCI) can be applied (e.g., for updating or replacing) the first stored closed-loop transmit power factor at the UE corresponding to the first antenna panel (e.g., it is used in conjunction with the use of SRIs in the list of one or more SRI-PUSCH-PowerControl IEs for the first panel). Furthermore, if, conversely, the DCI schedules the UE to transmit PUSCH from the second antenna panel, the first sorting TPC command (based on the sorting of the two TPC commands in a single DCI) can be applied (e.g., for updating or replacing) the second stored closed-loop transmit power factor at the UE corresponding to the second antenna panel (e.g., it is used in conjunction with the use of SRIs in the list of one or more SRI-PUSCH-PowerControl IEs for the second panel).

[0054] When CLPC is used for simultaneous PUSCH transmission based on a single DCI, it is possible that the use of the loop closure indicator can be omitted for DCIs with TPC commands (e.g., in the format 0_1, 0_2, and / or 2_2). Furthermore, it is possible that one or more TPC commands in the TPC field are represented by 2 bits. When two TPC commands are used, it is possible that the first TPC command corresponds to loop closure index 0, while the second TPC command corresponds to loop closure index 1.

[0055] PUSCH Power Scaling Enhancement

[0056] Figure 1 Figure 100 illustrates various options 102, 104 for performing power scaling for simultaneous PUSCH transmission according to an embodiment of this document. Figure 100 first illustrates a non-scaling scenario 110, which shows a first PUSCH transmission power 106 and a second PUSCH transmission power 108 for simultaneous transmission of two PUSCHs (e.g., on separate corresponding antenna panels, as discussed herein). As illustrated, the non-scaling scenario 110 exceeds the maximum transmission power limit 112 allowed at the UE (e.g., where the maximum transmission power limit 112 corresponds to UE capabilities and / or UE configuration). It should also be noted that... Figure 1 Reference line 114 is illustrated, which provides the boundary between the first PUSCH transmit power 106 and the second PUSCH transmit power 108 in the unscaled scenario 110, in order to facilitate understanding of options 102 and 104, which will now be discussed.

[0057] In the first option 102 (in Figure 1 In Option 1), the UE may reduce both the first PUSCH transmit power 106 and the second PUSCH transmit power 108 so that their sum is within the maximum transmit power limit 112, as illustrated.

[0058] Under option 102 (where the transmit power of both PUSCHs is reduced), various options exist for performing a reduction in the transmit power of each PUSCH. In the first case, the transmit power of each PUSCH can be reduced by the same percentage until the maximum transmit power limit is met. This case could correspond to, for example, reducing the transmit power of each PUSCH by the same amount of decibels (dB) until the maximum transmit power limit is met.

[0059] In another case, each of the transmit powers in the PUSCH can be reduced by the same absolute transmit power amount until the maximum transmit power limit is met.

[0060] In the second option 104 (in Figure 1 In Option 2, the UE may reduce the other of the first PUSCH transmit power 106 and the second PUSCH transmit power 108 before any reduction in the first PUSCH transmit power 106 and the second PUSCH transmit power 108. As can be seen, Option 2 specifically exemplifies the case where the second PUSCH transmit power 108 is adjusted first (while the first PUSCH transmit power 106 remains unadjusted).

[0061] Therefore, for simultaneous PUSCH transmission, corresponding to the disclosure herein, it is understandable that there may be cases where the transmission power of each PUSCH in the PUSCH may be different, and cases where the transmission power of each PUSCH in the PUSCH may be the same.

[0062] In some implementations of PUSCH transmit power scaling for simultaneous PUSCH transmission, a value of X dB may be considered for scaling purposes. Then, in a first option, the first PUSCH may initially reduce its transmit power by up to X dB. However, if the reduction in power required for the first PUSCH to bring the total transmit power of both PUSCHs within the maximum transmit power limit is greater than X dB, the first PUSCH may be discarded (and, for example, the second PUSCH may be transmitted separately). This discarding may be because, for example, it has been determined that the transmission of the first PUSCH, which has been reduced by more than X dB, is unlikely to be successfully received.

[0063] In the second option, the first PUSCH can initially reduce its transmit power by up to X dB. Once the X dB reduction is achieved at the first PUSCH, the second PUSCH can begin reducing its transmit power until the total transmit power of both PUSCHs is within the applicable maximum transmit power limit. This splitting of the reduction across the two PUSCHs prevents the first PUSCH from dropping below a power level that is unlikely to be successfully received.

[0064] It should be noted that under any of these options, the value of X can be configured by the network to the UE (e.g., based on the network congestion level and / or UE capabilities known at the network).

[0102] Figure 8 An example architecture of a wireless communication system 800 according to an embodiment disclosed herein is illustrated. The following description is provided for an example wireless communication system 800 operating in conjunction with LTE system standards and / or 5G or NR system standards provided by 3GPP technical specifications.

[0103] like Figure 8 As shown, the wireless communication system 800 includes UE 802 and UE 804 (but any number of UEs may be used). In this example, UE 802 and UE 804 are exemplified as smartphones (e.g., handheld touchscreen mobile computing devices capable of connecting to one or more cellular networks), but may also include any mobile or non-mobile computing device configured for wireless communication.

[0104] UE 802 and UE 804 can be configured to be communicatively coupled to RAN 806. In an implementation, RAN 806 can be NG-RAN, E-UTRAN, etc. UE 802 and UE 804 utilize connections (or channels) with RAN 806 (shown as connection 808 and connection 810, respectively), where each connection (or channel) includes a physical communication interface. RAN 806 may include one or more base stations (such as base station 812 and base station 814) implementing connection 808 and connection 810.

[0105] In this example, Connection 808 and Connection 810 are air interfaces that implement this type of communication coupling and can conform to the RAT used by RAN806, such as LTE and / or NR, for example.

[0106] In some implementations, UE 802 and UE 804 may also exchange communication data directly via sidelink interface 816. UE 804 is shown configured to access an access point (shown as AP 818) via connection 820. By way of example, connection 820 may include a local wireless connection, such as a connection conforming to any IEEE 802.11 protocol, wherein AP 818 may include Wi-Fi. ® Router. In this example, AP 818 may connect to another network (e.g., the Internet) without using CN 824.

[0107] In the implementation, UE 802 and UE 804 may be configured to communicate with each other or with base station 812 and / or base station 814 on a multi-carrier communication channel using orthogonal frequency division multiplexing (OFDM) communication signals according to various communication technologies, such as, but not limited to, orthogonal frequency division multiple access (OFDMA) communication technology (e.g., for downlink communication) or single-carrier frequency division multiple access (SC-FDMA) communication technology (e.g., for uplink and ProSe or sidelink communication) , but the scope of the implementation is not limited in this respect. The OFDM signal may include multiple orthogonal subcarriers.

[0108] In some implementations, all or part of base station 812 or base station 814 may be implemented as one or more software entities running on a server computer as part of a virtual network. Furthermore, or in other implementations, base station 812 or base station 814 may be configured to communicate with each other via interface 822. In implementations where wireless communication system 800 is an LTE system (e.g., when CN 824 is an EPC), interface 822 may be an X2 interface. This X2 interface may be defined between two or more base stations (e.g., two or more eNBs, etc.) connected to the EPC and / or between two eNBs connected to the EPC. In implementations where wireless communication system 800 is an NR system (e.g., when CN 824 is a 5GC), interface 822 may be an Xn interface. This Xn interface is defined between two or more base stations (e.g., two or more gNBs, etc.) connected to the 5GC, between a base station 812 (e.g., a gNB) connected to the 5GC and an eNB, and / or between two eNBs connected to the 5GC (e.g., CN 824).

[0109] RAN 806 is shown communicatively coupled to CN 824. CN 824 may include one or more network elements 826 configured to provide various data and telecommunications services to customers / subscribers (e.g., users of UE 802 and UE 804) connected to CN 824 via RAN 806. Components of CN 824 may be implemented in a single physical device or a separate physical device, including components for reading and executing instructions from machine-readable or computer-readable media (e.g., non-transitory machine-readable storage media).

[0110] In the implementation scheme, CN 824 can be an EPC, and RAN 806 can be connected to CN 824 via S1 interface 828. In the implementation scheme, S1 interface 828 can be divided into two parts: an S1 user plane (S1-U) interface, which carries service data between base station 812 or base station 814 and the service gateway (S-GW); and an S1-MME interface, which is the signaling interface between base station 812 or base station 814 and the mobility management entity (MME).

[0111] In the implementation scheme, CN 824 may be a 5GC, and RAN 806 may be connected to CN 824 via NG interface 828. In the implementation scheme, NG interface 828 may be divided into two parts: an NG user plane (NG-U) interface, which carries service data between base station 812 or base station 814 and user plane function (UPF); and an S1 control plane (NG-C) interface, which is the signaling interface between base station 812 or base station 814 and access and mobility management function (AMF).

[0112] Generally, application server 830 can be an element that provides Internet Protocol (IP) bearer resources (e.g., packet-switched data services) for use with CN 824. Application server 830 can also be configured to support one or more communication services (e.g., VoIP sessions, group communication sessions, etc.) for UE 802 and UE 804 via CN 824. Application server 830 can communicate with CN 824 via IP communication interface 832.

In embodiments with multiple antennas 912, wireless device 902 may fully utilize the spatial diversity of these multiple antennas 912 to transmit and / or receive multiple different data streams on the same time-frequency resource. This behavior may be referred to as, for example, multiple-input multiple-output (MIMO) behavior (referring to multiple antennas used at each of the transmitting and receiving devices to implement this aspect). MIMO transmission by wireless device 902 may be implemented according to pre-decoding (or digital beamforming) applied to wireless device 902, which multiplexes the data streams among antennas 912 based on known or assumed channel characteristics, such that each data stream is received with appropriate signal strength relative to the other streams at a desired location in the spatial domain (e.g., the location of the receiver associated with that data stream). Some embodiments may use a single-user MIMO (SU-MIMO) method (where all data streams are directed to a single receiver) and / or a multi-user MIMO (MU-MIMO) method (where individual data streams may be directed to individual (different) receivers at different locations in the spatial domain).

[0118] In some implementations with multiple antennas, the wireless device 902 can implement analog beamforming technology, whereby the phase of the signal transmitted by the antenna 912 is relatively adjusted so that the (joint) transmission of the antenna 912 can be directed (this is sometimes referred to as beam control).
