Description

Technical Field

[0001] (Cross - reference to Related Applications) This application claims the benefit and priority of U.S. Provisional Patent Application No. 63 / 465,834, filed on May 11, 2023, which is hereby incorporated by reference in its entirety.

[0002] The present invention generally relates to the field of wireless communication, and more particularly, to methods and apparatuses for radio resource management (RRM) for user equipment (UE) communicating with a base station, including methods and apparatuses for dynamic panel selection for uplink transmission from the UE.

Background Art

[0003] In a wireless communication network, a user equipment (UE) can communicate with a base station of the network by establishing a wireless link between the UE and the base station. In a 5G (New Radio or NR) or 4G (Long Term Evolution, LTE) wireless network, a UE can receive signaling and data from a serving base station in the downlink (DL) transmission direction or transmit signaling and data to the serving base station in the uplink (UL) transmission direction.

Summary of the Invention

[0004] For a UE having a different number of antenna ports for each panel and for transmission towards a single transmission and reception point (TRP), the UE needs to dynamically indicate to the base station the maximum number of antenna ports corresponding to the best panel for uplink (UL) transmission. This is due to the fact that the best panel for transmitting a given beam can change due to, for example, rotation of the UE.

[0005] Release 17 (R17) introduced the "UE Capability Index Reporting" feature (e.g., Section 38.822, Figure 23-1-4 of R17). In this environment, the UE reports the maximum number of sounding reference signal (SRS) antenna ports in the uplink control information (UCI) along with the L1 beam report (e.g., L1-Reference Signal Received Power (L1-RSRP)). For example, Table 6.3.1.1.2-8 in Section 38.212 of Release 17 provides an L1-based Channel State Information (CSI) reporting procedure. In this procedure, the UE can report up to four beam indices and their corresponding L1 measurements (RSRP or Signal Interference and Noise Ratio (SINR)), as well as the capability index associated with each beam, where the capability index represents the maximum number of SRS antenna ports.

[0006] R17 also supports L1-based procedures for group-based beam reporting, allowing the UE to report beam pairs (up to four) that may be received simultaneously. R17, Section 38.822, FG 23-5-1 provides the corresponding UE capabilities. For example, Table 6.3.1.1.2-8B in Section 38.212 of R17 provides an L1-based CSI reporting procedure. In this procedure, the UE consists of two channel measurement resource sets, and the UE can report up to four beam pair (e.g., called resource groups) indices, each of the two indices corresponding to a pair associated with one codec mode request (CMR) resource set. For each pair, the UE also reports a pair of L1-RSRPs associated with the beams in the pair.

[0007] These current implementations allow the UE to indicate the maximum number of antenna ports (through UL UCI), but do not provide dynamic UL panel selection. Furthermore, the current implementations do not enable non-code-based (NCB) physical uplink channel (PUSCH) transmission. The current implementations for UE capability index reporting are designed solely to report the maximum number of SRS antenna ports used only for CB-based PUSCH. Additionally, the current R17 implementations do not apply to multi-panel simultaneous UL transmission. There are no use cases where the best panel / beam pair should be reported by the UE.

[0008] As mentioned above, the current implementation in Rel.17 allows the UE to indicate the maximum number of antenna ports (through Uplink Control Information (UCI)), but does not provide dynamic UL panel selection. Furthermore, the current implementation in Rel.17 does not enable non-codebook-based (NCB) physical uplink channel (PUSCH) transmission. The current implementation in Rel.17 for UE capability index reporting is designed solely to report the maximum number of SRS antenna ports used only for code-based (CB) PUSCH. Additionally, the current R17 implementation does not apply to multi-panel simultaneous UL transmission. There is no use case where the best panel / beam pair should be reported by the UE.

[0009] Each embodiment of the present disclosure relates to the ability of a UE to dynamically indicate the maximum number of antenna ports for the best panel or across multiple panels. Furthermore, embodiments of the present disclosure enable a UE to dynamically indicate the maximum number of SRS antenna ports as part of an NCB push. Moreover, embodiments of the present disclosure enable multi-panel simultaneous UL transmission, providing a use case for the best panel / beam pair reported by the UE.

[0010] In one embodiment, a method for radio resource management (RRM) for user equipment (UE) communicating with a base station is disclosed, the method comprising determining the maximum number of available antenna ports per panel per band and transmitting the maximum number of available antenna ports per panel per band from the UE to the base station. In one embodiment, the method further comprises transmitting the maximum number of available antenna ports per band across multiple panels from the UE to the base station.

[0011] In another embodiment, a method is disclosed for a UE communicating with a base station, the method comprising sending a UE capability index report from the UE to the base station, which includes the maximum number of Sounding Reference Signal (SRS) resources in an SRC resource set in use configured as non-codebook (NCB) based, or the maximum number of SRS resources in an SRC resource set in use configured as codebook (CB) based.

[0012] In another embodiment, a method for a UE communicating with a base station is disclosed, which includes configuring multiple SRS resource sets in use configured as NCB in the UE, or multiple SRS resource sets in use configured as CB in the UE. In one embodiment, the number of configured SRS resource sets depends on the capabilities of the UE. In one embodiment, when an SRS resource set is configured as CB, the SRS resources in each set include the same number of SRS antenna ports, while different SRS resource sets include different numbers of SRS resource sets. In one embodiment, when an SRS resource set is configured as NCB, the SRS resource set includes different numbers of SRS resources in each set.

[0013] In another embodiment, a method for a UE communicating with a base station is disclosed, which includes transmitting from the UE to the base station a dynamically determined maximum number of SRS resources for an NCB-based physical uplink channel (PUSCH) corresponding to the best panel for UL transmission, or a dynamically determined maximum number of antenna ports for a CB-based PUSCH corresponding to the best panel for UL transmission. In one embodiment, the dynamically determined maximum number of SRS resources or antenna ports for an NCB or CB-based PUSCH is transmitted to the base station in uplink control information (UCI) based on the physical layer (L1). In one embodiment, the UCI includes at least one of CRI / SSBRI, L1-RSRP / SINR, or capability index. In one embodiment, the method further includes dropping the transmission if the transmission exceeds the UE capability, transmitting only through antenna ports for CB or a few SRS resources for NCB under L1 reporting, or, in the case of aperiodic (AP)-SRS, defining it as an error. In one embodiment, when SRS transmissions in a particular serving cell overlap in time, the method includes 1) dropping both SRS transmission opportunities, 2) transmitting only through the antenna port for the CB or some SRS resources for the NCB under the most recent UE L1 capability report, or defining it as an error case, when SRS transmissions correspond to different sets of SRS resources having different numbers of SRS resources for an NCB base or different numbers of SRS ports for a CB base.

[0014] In additional embodiments, a method is disclosed for a UE communicating with a base station, the method comprising transmitting from the UE to the base station through dynamic uplink (UL) uplink control information (UCI) which includes at least CSI-RS resource indicators (CRIs) for at least pairs of beams for a group of multiple transmit / receive points (mTRPs), L1 reference signal received power (RSRP), and capability index (CI). In one embodiment, the UL UCI includes pairs of trios, each containing a first trio and a second trio. In one embodiment, the first trio in each pair corresponds to one of the channel measurement resource sets, and the second trio in each pair corresponds to another channel measurement resource set. In one embodiment, each trio includes a CRI associated with the channel measurement resource set, a corresponding RSRP, and a CI associated with a particular beam. In one embodiment, the UE dynamically indicates to the base station, through the UL UCI, at least the CRI, the L1-RSRP, and a UL / DL association instead of a capability index (CI). In one embodiment, a single group-based report applicable to both DL for simultaneous reception and UL for simultaneous transmission is provided on the UL UCI. In one embodiment, the indication provided for UL / DL association by 2 bits or 1 bit (per pair) includes, for 2 bits, 00 (DL only), 01 (UL only), 10 (applicable to both UL and DL) and 11 (reserved), or for 1 bit, 0 (DL only) and 1 (applicable to both UL and DL).

[0015] In another type of embodiment, a UE for implementing radio resource management (RRM) for a UE connected to a base station comprises at least one antenna port, at least one radio configured to communicate with a base station using at least one antenna port, and at least one processor coupled to the at least one radio, wherein the at least one processor is configured to perform operations including determining the maximum number of antenna ports available per panel per band, and commanding the base station to transmit the maximum number of antenna ports available per panel per band. In one embodiment, the processor further includes commanding the base station to transmit the maximum number of antenna ports available per panel per band across multiple panels.

[0016] In an additional embodiment, a UE connected to a base station is disclosed, comprising at least one antenna port, at least one radio configured to communicate with the base station using at least one antenna port, and at least one processor coupled to the at least one radio, wherein the at least one processor is configured to perform operations including commanding the base station to send a UE capability index report including the maximum number of sounding reference signal (SRS) resources in an SRC resource set in use configured as non-codebook (NCB) based, or the maximum number of SRS resources in an SRC resource set in use configured as codebook (CB) based.

In one embodiment, the number of configured SRS resource sets depends on the capabilities of the UE. In one embodiment, when an SRS resource set is set to use set to CB, the SRS resources in each set include the same number of SRS antenna ports, while different SRS resource sets include different numbers of SRS resource sets. In one embodiment, when an SRS resource set is set to use set to NCB, the SRS resource set includes different numbers of SRS resources in each set.

In one embodiment, the dynamically determined maximum number of SRS resources or antenna ports for an NCB or CB-based PUSCH is transmitted to the base station in uplink control information (UCI) based on the physical layer (L1). In one embodiment, the UCI includes at least one of CRI / SSBRI, L1-RSRP / SINR, or capability index. In one embodiment, if a transmission exceeds UE capability, the processor further includes commanding to drop the transmission, transmit only through antenna ports for CBs or a few SRS resources for NCBs under L1 reporting, or, in the case of aperiodic (AP)-SRS, define it as an error. In one embodiment, when SRS transmissions in a particular serving cell overlap in time, such that SRS transmissions correspond to different sets of SRS resources having different numbers of SRS resources for NCB bases or different numbers of SRS ports for CB bases, the processor includes commanding to 1) drop both SRS transmission opportunities, 2) transmit only through antenna ports for CBs or a few SRS resources for NCBs under the most recent UE L1 capability report, or define it as an error case.

[0019] In an additional embodiment, a UE connected to a base station is disclosed, comprising at least one antenna port, at least one radio configured to communicate with the base station using at least one antenna port, and at least one processor coupled to the at least one radio, the at least one processor configured to perform operations including commanding the base station to transmit through dynamic uplink (UL) uplink control information (UCI) which includes at least CSI-RS resource indicators (CRI) for at least pairs of beams for a group of multiple transmission and reception points (mTRPs), L1 reference signal received power (RSRP), and capability index (CI).

[0030] The following description includes numerous specific details in order to provide a complete description of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention can be practiced without these specific details. In other examples, well-known components, structures and techniques are not shown in detail so as not to hinder the understanding of this description.

[0031] Any reference in this specification to “several embodiments” or “embodiments” means that certain mechanisms, structures, or characteristics described in relation to those embodiments may be included in at least one embodiment of the present invention. The phrase “in some embodiments” appearing in various parts of this specification does not necessarily refer to the same embodiment in all instances.

[0032] In the following descriptions and claims, the terms “joined” and “connected” may be used together with their derivatives. It should be understood that these terms are not intended to be synonymous with one another. “Joined” is used to indicate that two or more elements, which may or may not be in direct physical or electrical contact with each other, work together or interact with each other. “Connected” is used to indicate the establishment of communication between two or more elements that are joined together.

[0033] The processes shown in the following diagrams are executed by processing logic, which includes hardware (e.g., circuits, dedicated logic), software (such as general-purpose computer systems or those running on dedicated machines), or a combination of both. These processes are described below in terms of several sequential operations, but it should be understood that some of the operations described can be executed in different orders. Furthermore, some operations may be executed in parallel rather than sequentially.

[0034] The terms "server," "client," and "device" are intended to refer to a data processing system in general, rather than to a specific form factor for a server, client, and / or device.

[0035] Figure 1 shows a simplified, exemplary wireless communication system according to one aspect of the present disclosure. Note that the system in Figure 1 is merely one example of a possible system, and the features of the present disclosure can be implemented in any of the various systems as desired.

[0036] As shown in the figure, the exemplary wireless communication system includes a base station 102A, which communicates with one or more user devices 106A, 106B-106N via a transmission medium. Each of the user devices may be referred to herein as a “user equipment” (UE). Thus, user device 106 is referred to as a UE or UE device.

[0037] Base station (BS) 102A may be a base transceiver station (BTS) or a cellular base station ("cellular base station"), and may include hardware that enables wireless communication with UE 106A to 106N.

[0038] The communication area (or coverage area) of a base station may be referred to as a “cell”. Base stations 102A and UE106 may be configured to communicate over a medium using any of the various radio access technologies (RATs), also known as wireless communication technologies or telecommunications standards, such as GSM, UMTS (associated with, for example, WCDMA®, or TD-SCDMA air interface), LTE, LTE-Advanced (LTE-A), 5G NR, HSPA, and 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD). Note that when base station 102A is implemented in the context of LTE, base station 102A may be referred to as an “eNodeB” or “eNB” instead. Note that when base station 102A is implemented in the context of 5G NR, base station 102A may be referred to as an “gNodeB” or “gNB” instead.

[0039] As shown in the figure, base station 102A may also be equipped to communicate with network 100 (for example, among various possibilities, the core network of a cellular service provider, a telecommunications network such as the Public Switched Telephone Network (PSTN), and / or the Internet). Thus, base station 102A can facilitate communication between user devices and / or between user devices and network 100. In particular, cellular base station 102A can provide UE 106 with various telecommunications capabilities such as voice, SMS, and / or data services.

[0040] Base stations 102 and other similar base stations (such as base stations 102B...102N) operating according to the same or different cellular communication standards may be provided as a cell network, which may provide continuous or nearly continuous overlapping services to UE106A-106N and similar devices over a geographical area via one or more cellular communication standards.

[0041] Therefore, as shown in Figure 1, base station 102A can function as a “serving cell” for UEs 106A to 106N, and each UE 106 can also receive signals from one or more other cells (which may be provided by base stations 102B to 102N and / or any other base stations) (within their communication range, if possible). Such cells can also facilitate communication between user devices and / or between user devices and the network 100. Such cells may include “macro” cells, “micro” cells, “pico” cells, and / or cells that provide any of the various other granularities of service area sizes. For example, base stations 102A to 102B shown in Figure 1 may be macrocells, while base station 102N may be a microcell. Other configurations are also possible.

[0042] In some embodiments, base station 102A may be a next-generation base station, for example, a 5G New Radio (5G NR) base station, or a "gNB". In some embodiments, the gNB may be connected to a legacy evolved packet core (EPC) network and / or an NR core (NR Core, NRC) network. In addition, a gNB cell may include one or more transition and receive points (TRPs). In addition, UEs capable of operating in accordance with 5G NR may be connected to one or more TRPs in one or more gNBs.

[0043] It should be noted that UE106 may be capable of communicating using multiple wireless communication standards. For example, UE106 may be configured to communicate using at least one cellular communication protocol (e.g., GSM, UMTS (associated with WCDMA® or TD-SCDMA air interfaces), LTE, LTE-A, 5G NR, HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD)) in addition to a radio network (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer). In addition, or alternatively, UE106 may be configured to communicate using one or more Global Navigational Satellite Systems (GNSS, e.g., GPS or GLONASS), one or more mobile television broadcasting standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols, if desired. Other combinations of wireless communication standards (including three or more wireless communication standards) are also possible.

[0044] Figure 2 shows a UE 106 communicating directly with a base station 102 through uplink and downlink communications, according to one aspect of the present disclosure. The UE 106 may be a cellular communication-capable device such as a mobile phone, a handheld device, a computer or tablet, or substantially any type of wireless device. The UE 106 may include a processor configured to execute program instructions stored in memory. By executing such stored instructions, the UE 106 can perform any of the embodiments of the method described herein. Alternatively or in addition, the UE 106 may include a programmable hardware element, such as a field-programmable gate array (FPGA), configured to perform any of the embodiments of the method described herein, or any part of any of the embodiments of the method described herein.

[0045] UE106 may include one or more antennas for communication using one or more wireless communication protocols or technologies. In some embodiments, UE106 may be configured to communicate, for example, using CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD) or LTE using a single shared radio, and / or using GSM or LTE using a single shared radio. The shared radio may be coupled to a single antenna or to multiple antennas (e.g., for Multiple-Input Multiple Output (MIMO)) to perform wireless communication. Generally, the radio may include any combination of a baseband processor, analog RF signal processing circuits (e.g., including filters, mixers, oscillators, amplifiers, etc.), or digital processing circuits (e.g., for digital modulation and other digital processing). Similarly, the radio may implement one or more receive and transmit chains using the above hardware. For example, UE106 may share one or more parts of the receive and / or transmit chains among multiple wireless communication technologies such as those described above.

[0046] In some embodiments, UE106 may include a separate transmit and / or receive chain (e.g., including separate antennas and other radio components) for each radio communication protocol that UE106 is configured to use for communication. Further possibilities include one or more radios shared among multiple radio communication protocols and one or more radios used by only one radio communication protocol. For example, UE106 may include a shared radio for communication using either LTE or 5G NR (or LTE or 1xRTT, or LTE or GSM) and separate radios for communication using Wi-Fi and Bluetooth, respectively. Other configurations are also possible.

[0047] Figure 3 shows an exemplary, simplified block diagram of a communication device 106 according to one aspect of the present disclosure. Note that the block diagram of the communication device in Figure 3 is only one example of a possible communication device. According to the embodiment, the communication device 106 may be, among other devices, a user equipment (UE) device, a mobile device or mobile station, a radio device or radio station, a desktop computer or computing device, a mobile computing device (e.g., a laptop computer, notebook computer, or portable computing device), a tablet, and / or a combination of devices. As shown in the figure, the communication device 106 may include a set of components 300 configured to perform a core function. For example, this set of components may be implemented as a system on a chip (SOC) which may include parts for various purposes. Alternatively, this set of components 300 may be implemented as separate components or groups of components for various purposes. The set of components 300 may be coupled (e.g., directly or indirectly, in a communicative manner) to various other circuits of the communication device 106.

[0048] For example, the communication device 106 may include various types of memory (including, for example, NAND flash 310), an input / output interface such as a connector I / F 320 (for connecting to, for example, a computer system, a dock, a charging station, input devices such as a microphone, camera, or keyboard, and output devices such as a speaker), a display 360 which may be integrated with or outside the communication device 106, a cellular communication circuit 330 for 5G NR, LTE, GSM, etc., and a short-to-medium range wireless communication circuit 329 (e.g., Bluetooth® and WLAN circuit). In some embodiments, the communication device 106 may include a wired communication circuit (not shown), such as a network interface card for Ethernet.

[0049] The cellular communication circuit 330 may be coupled (e.g., directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 335 and 336, as shown in the figure. The short-to-medium range wireless communication circuit 329 may also be coupled (e.g., directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 337 and 338, as shown in the figure. Alternatively, the short-to-medium range wireless communication circuit 329 may be coupled (e.g., directly or indirectly, in a communicative manner) to antennas 335 and 336, in addition to or instead of coupling (e.g., directly or indirectly, in a communicative manner) to antennas 337 and 338. The short-to-medium range wireless communication circuit 329 and / or the cellular communication circuit 330 may include multiple receive chains and / or multiple transmit chains for receiving and / or transmitting multiple spatial streams in a multi-input multiple-output (MIMO) configuration, such as.

[0050] In some embodiments, as further described below, the cellular communication circuit 330 may include dedicated receiving chains for multiple radio access technologies (RATs) (e.g., a first receiving chain for LTE and a second receiving chain for 5G NR) (e.g., including dedicated processors and / or radios and / or directly or indirectly coupled to the dedicated processors and / or radios in a communicative manner). In addition, in some embodiments, the cellular communication circuit 330 may include a single transmitting chain that can be switched between radios dedicated to a particular RAT. For example, a first radio may be dedicated to a first RAT, e.g., LTE, and communicate with a dedicated receiving chain and a transmitting chain shared with an additional radio, e.g., a second radio, and a second radio may be dedicated to a second RAT, e.g., 5G NR, and communicate with a dedicated receiving chain and a shared transmitting chain.

[0051] The communication device 106 may also include and / or be configured to be used with one or more user interface elements. The user interface elements may include any of a variety of elements, such as a display 360 (which may be a touchscreen display), a keyboard (which may be a separate keyboard or implemented as part of a touchscreen display), a mouse, a microphone and / or a speaker, one or more cameras, one or more buttons, and / or any of a variety of other elements capable of providing information to the user and / or receiving or interpreting user input.

[0052] The communication device 106 may further include one or more smart cards 345, each smart card 345 including subscriber identity module (SIM) functionality such as a Universal Integrated Circuit Card (UICC).

[0053] As shown in the figure, the SOC 300 may include one or more processors 302 capable of executing program instructions for the communication device 106, and a display circuit 304 capable of performing graphics processing and providing display signals to the display 360. The one or more processors 302 may be coupled to a Memory Management Unit (MMU) 340, which may be configured to receive addresses from the one or more processors 302 and to translate these addresses to locations in memory (e.g., memory 306, read-only memory (ROM) 350, NAND flash memory 310), and / or other circuits or devices such as the display circuit 304, the short-range wireless communication circuit 229, the cellular communication circuit 330, the connector I / F 320, and / or the display 360. The MMU 340 may be configured to perform memory protection and page table conversion or setup. In some embodiments, the MMU 340 may be included as part of the one or more processors 302.

[0054] As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuits. The communication device 106 may also be configured to determine physical downlink shared channel scheduling resources for user equipment devices and base stations. Furthermore, the communication device 106 may be configured to group and select component carriers (CCs) from a wireless link and determine a virtual CC from the selected group of CCs. The wireless device may also be configured to perform physical downlink resource mapping based on an aggregated resource matching pattern of the group of CCs.

[0055] As described herein, the communication device 106 may include hardware and software components for implementing the above-described features for determining physical downlink shared channel scheduling resources for the communication device 106 and the base station. The processor 302 of the communication device 106 may be configured to implement some or all of the features described herein by executing program instructions stored in a storage medium (e.g., a non-temporary computer-readable storage medium). Alternatively (or in addition), the processor 302 may be configured as a programmable hardware element such as an FPGA (Field-Programmable Gate Array) or as an Application Specific Integrated Circuit (ASIC). Alternatively (or in addition), the processor 302 of the communication device 106 may be configured to implement some or all of the features described herein together with one or more of the other components 300, 304, 306, 310, 320, 329, 330, 340, 345, 350, 360.

[0056] In addition, as described herein, the processor 302 may include one or more processing elements.

[0058] Figure 4 shows an exemplary block diagram of a base station 102 according to one aspect of the present disclosure. Note that the base station in Figure 4 is just one example of a possible base station. As shown in the figure, the base station 102 may include one or more processors 404 capable of executing program instructions for the base station 102. The processors 404 may also be coupled to a memory management unit (MMU) 440, which may be configured to receive addresses from the processors 404 and translate those addresses to locations in memory (e.g., memory 460 and read-only memory (ROM) 450) or other circuits or devices.

[0059] The base station 102 may include at least one network port 470. The network port 470 may be connected to a telephone network and configured to provide access to the telephone network to multiple devices such as UE 106, as described above in Figures 1 and 2.

[0060] Network port 470 (or additional network ports) may also, or alternatively, be configured to connect to a cellular network, such as the core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices such as UE106. In some cases, network port 470 may connect to a telephone network via the core network, and / or the core network may provide a telephone network (for example, between other UEs serviced by the cellular service provider).

[0061] In some embodiments, base station 102 may be a next-generation base station, for example, a 5G New Radio (5G NR) base station, or a "gNB". In such embodiments, base station 102 may be connected to a legacy evolved packet core (EPC) network and / or an NR core (NRC) network. In addition, base station 102 may be considered a 5G NR cell and may include one or more transition and receive points (TRPs). In addition, UEs capable of operating according to 5G NR may be connected to one or more TRPs in one or more gNBs.

[0062] The base station 102 may include at least one antenna 434, and, if possible, more antennas. At least one antenna 434 may be configured to operate as a radio transceiver and may be further configured to communicate with UE 106 via radio 430. Antenna 434 communicates with radio 430 via a communication chain 432. The communication chain 432 may be a receive chain, a transmit chain, or both. Radio 430 may be configured to communicate via a variety of radio communication standards, including, but not limited to, 5G NR, LTE, LTE-A, GSM, UMTS, CDMA2000, and Wi-Fi.

[0063] Base station 102 may be configured to communicate using multiple wireless communication standards. In some cases, base station 102 may include multiple radios, which may enable base station 102 to communicate according to multiple wireless communication technologies. For example, one possibility is that base station 102 may include an LTE radio for performing communication according to LTE, and a 5G NR radio for performing communication according to 5G NR. In such a case, base station 102 may be capable of operating as both an LTE base station and a 5G NR base station. Another possibility is that base station 102 may include a multimode radio, which may be capable of performing communication according to any of multiple wireless communication technologies (e.g., 5G NR and Wi-Fi, LTE and Wi-Fi, LTE and UMTS, LTE and CDMA2000, UMTS and GSM, etc.).

[0064] As further described below in this specification, BS102 may include hardware and software components for implementing or supporting the implementation of the features described herein. The processor 404 of the base station 102 may be configured to implement or support some or all of the methods described herein by executing program instructions stored in a storage medium (e.g., a non-temporary computer-readable storage medium). Alternatively, the processor 404 may be configured as a programmable hardware element such as an FPGA (Field-Programmable Gate Array), or as an ASIC (Application-Specific Integrated Circuit), or a combination thereof. Alternatively (or in addition), the processor 404 of BS102 may be configured to implement or support some or all of the features described herein, together with one or more of the other components 430, 432, 434, 440, 450, 460, and 470.

[0065] In addition, as described herein, a processor(s) 404 may consist of one or more processing elements. In other words, one or more processing elements may be contained within a processor(s) 404. Thus, a processor(s) 404 may include one or more integrated circuits (ICs) configured to perform the functions of a processor(s) 404. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of a processor(s) 404.

[0066] Furthermore, as described herein, the radio 430 may consist of one or more processing elements. In other words, one or more processing elements may be contained within the radio 430. Thus, the radio 430 may include one or more integrated circuits (ICs) configured to perform the functions of the radio 430. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the radio 430.

[0067] Figure 5 shows an exemplary, simplified block diagram of a cellular communication circuit according to one aspect of the present disclosure. Note that the block diagram of the cellular communication circuit in Figure 5 is merely one example of a possible cellular communication circuit. According to the embodiment, the cellular communication circuit 330 may be included in a communication device such as the communication device 106 described above. As described above, the communication device 106 may be, among other devices, a user equipment (UE) device, a mobile device or mobile station, a radio device or radio base station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet, and / or a combination of devices.

[0068] The cellular communication circuit 330 may be coupled (for example, directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 335a-b and 336, as shown (in Figure 3). In some embodiments, the cellular communication circuit 330 may include dedicated receiving chains for multiple RATs (e.g., a first receiving chain for LTE and a second receiving chain for 5G NR) (e.g., including dedicated processors and / or radios and / or being communicatively coupled directly or indirectly to the dedicated processors and / or radios). For example, as shown in Figure 5, the cellular communication circuit 330 may include modems 510 and 520. Modem 510 may be configured to communicate according to a first RAT, such as LTE or LTE-A, and modem 520 may be configured to communicate according to a second RAT, such as 5G NR.

[0069] As shown in the figure, the modem 510 may include one or more processors 512 and a memory 516 that communicates with the processors 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuits for transmitting and receiving radio signals. For example, the RF front end 530 may include a receive circuitry (RX) 532 and a transmit circuitry (TX) 534. In some embodiments, the receive circuitry 532 may communicate with a downlink (DL) front end 550 which may include circuits for receiving radio signals via an antenna 335a.

[0070] Similarly, the modem 520 may include one or more processors 522 and a memory 526 that communicates with the processors 522. The modem 520 may communicate with an RF front end 540. The RF front end 540 may include circuits for transmitting and receiving radio signals. For example, the RF front end 540 may include a receiving circuit 542 and a transmitting circuit 544. In some embodiments, the receiving circuit 542 may communicate with a DL front end 560 which may include circuits for receiving radio signals via an antenna 335b.

[0071] In some embodiments, switch 570 may couple a transmitting circuit 534 to an uplink (UL) front end 572. In addition, switch 570 may couple a transmitting circuit 544 to an UL front end 572. The UL front end 572 may include a circuit for transmitting a radio signal via an antenna 336. Thus, when the cellular communication circuit 330 receives a command to transmit according to a first RAT (e.g., supported via a modem 510), switch 570 may be switched to a first state that enables the modem 510 to transmit a signal according to the first RAT (e.g., via a transmission chain including transmitting circuit 534 and the UL front end 572). Similarly, when the cellular communication circuit 330 receives a command to transmit according to a second RAT (e.g., supported via a modem 520), switch 570 may be switched to a second state that enables the modem 520 to transmit a signal according to a second RAT (e.g., via a transmission chain including transmitting circuit 544 and the UL front end 572).

[0072] As described herein, the modem 510 may include hardware and software components for implementing the above-described functions for selecting periodic resource portions for user equipment devices and base stations, as well as various other techniques described herein. The processor 512 may be configured to implement some or all of the features described herein by executing program instructions stored in a storage medium (e.g., a non-temporary computer-readable storage medium). Alternatively (or in addition), the processor 512 may be configured as a programmable hardware element such as an FPGA (Field-Programmable Gate Array) or as an ASIC (Application-Specific Integrated Circuit). Alternatively (or in addition), the processor 512 may be configured to implement some or all of the features described herein together with one or more of the other components 530, 532, 534, 550, 570, 572, 335, and 336.

[0073] In addition, as described herein, the processor 512 may include one or more processing elements. Therefore, the processor 512 may include one or more integrated circuits (ICs) configured to perform the functions of the processor 512. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the processor 512.

[0074] As described herein, the modem 520 may include hardware and software components for implementing the above-described features for selecting periodic resources on a radio link between the UE and the base station, as well as various other techniques described herein. The processor 522 may be configured to implement some or all of the features described herein by executing program instructions stored in a storage medium (e.g., a non-temporary computer-readable storage medium). Alternatively (or in addition), the processor 522 may be configured as a programmable hardware element such as an FPGA (Field-Programmable Gate Array) or as an ASIC (Application-Specific Integrated Circuit). Alternatively (or in addition), the processor 522 may be configured to implement some or all of the features described herein together with one or more of the other components 540, 542, 544, 550, 570, 572, 335, and 336.

[0075] In addition, as described herein, the processor 522 may include one or more processing elements. Thus, the processor 522 may include one or more integrated circuits (ICs) configured to perform the functions of the processor 522. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the processor 522.

[0076] As mentioned above, the current implementation in Rel.17 allows the UE to indicate the maximum number of antenna ports (through Uplink Control Information (UCI)), but does not provide dynamic UL panel selection. Furthermore, the current implementation in Rel.17 does not enable non-codebook-based (NCB) physical uplink channel (PUSCH) transmission. The current implementation in Rel.17 for UE capability index reporting is designed solely to report the maximum number of SRS antenna ports used only for codebook-based (CB) PUSCH. Additionally, the current R17 implementation does not apply to multi-panel simultaneous UL transmission. There is no use case where the best panel / beam pair should be reported by the UE.

[0077] Each embodiment of the present disclosure relates to the ability of a UE to dynamically indicate the maximum number of antenna ports for the best panel or across multiple panels. Furthermore, embodiments of the present disclosure enable a UE to dynamically indicate the maximum number of sound reference signal (SRS) antenna ports as part of an NCB push. Moreover, embodiments of the present disclosure enable multi-panel simultaneous UL transmission, providing a use case for the best panel / beam pair reported by the UE.

[0078] Referring to Figure 6, Figure 6 shows a flowchart of the process for implementing Radio Resource Management (RRM) for the UE, and in particular for providing various new functions for reporting the UE's antenna ports. In particular, in one embodiment, a new UE capability is defined per band so that the UE 106 can indicate the maximum number of antenna ports available to the base station 102 (hereinafter referred to as gNB). As shown in Figure 6, the UE 106 may transmit and report to the gNB 102 the maximum number of available antenna ports per panel or per band across multiple panels (operation 610). For example, the reported number may be per panel or across multiple panels (for example, if the UE 106 shares a digital port). As an example, candidate values ​​may be {1, 2, 4, 6, 8}.

[0079] In another embodiment, the capabilities of the existing R17 for “UE Capability Index Reporting” may be revised, or new capabilities may be defined, such that the number reported for gNB102 represents either the maximum number of SRS resources in a Sounding Reference Signal (SRS) resource set in a non-codebook (NCB) based usage (operation 620), or the maximum number of SRS antenna ports for SRS resources in an SRS resource set in a codebook (CB) based usage (operation 630).

[0080] In another embodiment, while the existing R17 capability, "UE capability index reporting," is used for codebook (CB)-based PUSCH, a new capability may be utilized that defines only the maximum number of SRS resources in an SRS resource set when configured as non-codebook (NCB)-based.

[0081] In one embodiment, UE106 may consist of multiple SRS resource sets in a “non-codebook” usage, or multiple SRS resource sets in a “codebook” usage (operation 640). Under these implementations, the configuration of multiple SRS resource sets in the same usage does not necessarily result in mTRP operation, as will be described later. For each usage, the number of configured SRS resource sets depends on the UE capability. For each usage, different SRS resource sets may have different resource types (P / SP / AP). In the case of SRS resource sets in a “codebook” usage, the SRS resources within each set may have the same number of SRS antenna ports, nrofSRS-Ports (e.g., several SRS ports), but different SRS resource sets may have different numbers of nrofSRS-Ports. In the case of SRS resource sets in a “non-codebook” usage, different SRS resource sets may have different numbers of SRS resources within each set.

[0082] The configuration can be under UE 106 capability, as described above. For example, if UE106 reports a value of 4 in CB-based PUSCH (e.g., operation 610), UE106 may consist of two sets of SRS resources in the usage set in the "codebook," one set having SRS resources with nrofSRS-Ports set to 2, and the other set having SRS resources with nrofSRS-Ports set to 4. Note that the conflict of different SRS resources corresponding to different sets of SRS resources associated with the same or different time-domain behavior will be discussed in more detail later. For example, the behavior of the UE when an AP-SRS (non-periodic SRS) with two antenna ports temporally overlaps with a P-SRS (periodic SRS) with four antenna ports.

[0083] Referring further to Figure 7, which shows a flowchart of the process for implementing Radio Resource Management (RRM) for the UE and, in particular, for providing various new functions for reporting the UE's antenna ports. In one embodiment, UE 106 dynamically indicates the maximum number of SRS resources corresponding to the best panel for UL transmission to gNB 102 (e.g., for NCB-based PUSCH) (operation 710). Or, in one embodiment, UE 106 dynamically indicates the maximum number of antenna ports corresponding to the best panel for UL transmission to gNB 102 (e.g., for CB-based PUSCH) (operation 720).

[0084] These procedures, like existing standards, can be based on L1 measurements and UCI reporting. For example, N trios of (CRI / SSBRI, L1-RSRP / SINR, and capability index) are reported in the CSI (where N is at most 4). Each new aspect concerns interpreting the “capability index” in Rel. 17 38.212 to reflect not only CB-based PUSCH but also NCB-based PUSCH, based on the aforementioned capabilities.

[0085] Regarding SRS transmission opportunities corresponding to an SRS resource set, if the transmission exceeds the L1 indicated by the UE capability as described above, for example, for a given transmit beam, if UE106 dynamically indicates through UL UCI that the best panel currently has only two antenna ports, but UE106 is configured to transmit periodic SRS with nrofSRS-Ports set to 4 in use as set in the "codebook", then various options can be implemented: 1) Option 1 is for UE106 to drop the SRS transmission opportunity; 2) Option 2 is for UE106 to transmit only through ports (for CBs) or some SRS resources (for NCBs) (in the above example, SRS with two antenna ports) under the latest UE L1 report; or 3) Option 3 is for AP-SRS to be an error case. However, for P / SP-SRS, one of the above options can be adopted.

[0086] SRS transmission opportunities may overlap in time if they correspond to different numbers of SRS resources, different sets of SRS resources (in the case of NCB-based systems), or different nrofSRS-Ports (in the case of CB-based systems). For example, an SRS resource with nrofSRS-Ports set to 4 may overlap with an SRS resource with nrofSRS-Ports set to 2. The following scenario is considered an error case and must be avoided by the scheduler: at least one of the overlapping SRSs is an AP-SRS (non-periodic SRS), and the AP-SRS exceeds the L1 shown by the best panel of the UE. Other possible remaining scenarios: 1) Option 1: UE106 drops both SRS transmission opportunities. Option 2: UE106 transmits only through ports (for CBs) or some SRS resources (for NCBs) that are under the most recent UE L1 capability report. For example, if UE106 dynamically indicates through the UL UCI that, for a given transmit beam, the best panel currently consists of only two antenna ports, UE106 will drop the SRS where nrofSRS-Ports is set to 4. Option 3: For a UE with the capability report described above, UE106 may consist only of SRS resource sets configured so that the resource type is "aperiodic", and for AP-SRS, such collisions are not expected / allowed. Option 4: Such collisions are considered error cases.

[0087] As previously mentioned, the procedure for single TRP (sTRP) operation may be CB-based, but similar operation may apply for NCB-based operation. As previously mentioned, the UE may report the maximum number of SRS antenna ports through capability signaling. As previously mentioned, the gNB may configure the UE with multiple SRS resource sets, each with nrofSRS-Ports less than or equal to the reported capability (e.g., in 1-1). Furthermore, the UE reports pairs (CRI / SSBRI and number of SRS antenna ports) in the UL UCI. The number of reported pairs may be 1 or up to 4, depending on the UE capability. The gNB triggers the SRS resource set associated with the L1 capability report in the UCI. For example, an SRS resource set with nrofSRS-Ports set to 2 is triggered using DCI format 0_1, 0_2, 1_1, 1_2, or 2_3 (see Rel. 17 38.212, Table 7.3.1.1.2-24: SRS Requests).

[0088] The following describes additional behaviors for multiple TRPs (mTRPs). Specifically, it describes additional changes and improvements to the TDM-based mTRP behavior of Rel. 17 and the SDM-based mTRP behavior of Rel. 18.

[0089] In one embodiment of the process, in the case of mTRP-based operation, UE106 dynamically displays group-based data (CRI / SSBRI, L1-RSRP / SINR, and capability index) through UL UCI. UE106 consists of two channel measurement resource sets (similar to group-based reporting for DL). Referring to Figure 8, UE106 dynamically displays group-based capability for a pair of beams to gNB102 (operation 810). Specifically, UE106 reports pairs of trios (first trio and second trio) as follows: the first trio in each pair (or referred to as a resource group in DL) corresponds to one of the channel measurement resource sets, and the second trio in each pair corresponds to the other channel measurement resource set. The 1-bit resource set indicator in the CSI report indicates the first or second channel measurement resource set, with a value of 0 or 1, respectively. Each trio consists of: the CRI (or SSBRI) associated with the indicated channel measurement resource set, the corresponding RSRP (or SINR), and the capability index associated with that particular beam, distinct from the DL.

[0090] Exemplary components (CSI report number and CSI field, for only two pairs) are described below and can be seen in the following example table.

[0091] Note that if UE106 is configured as an RRC with SDM / SFN-based (e.g., Rel. 18) mTRP operation, the dynamic CSI report indicates that UE106 is capable of simultaneously transmitting on the beams associated by the corresponding CSI / SSBRI for each pair. If UE106 is configured as an RRC with TDM-based (e.g., Rel. 17) mTRP operation, the dynamic CSI report indicates that the indicated beams can be used for TDM operation. If neither SDM / SFN nor TDM is configured, the aforementioned sTRP operation may apply.

[0092] An example of a table to support the CSI report number and CSI field is shown below. [Table 1]

[0093] In another embodiment, in the case of mTRP-based operation, UE106 dynamically indicates group-based relationships (CRI / SSBRI, L1-RSRP / SINR, and UL / DL) through UL UCI.

[0094] This procedure is similar to the one described above, unless it is assumed that both panels always have the same and fixed capabilities so that no capability index is reported. Under this proposal, a single group-based report is provided on the UL UCI, applicable to both DL (for simultaneous reception) and UL (for simultaneous transmission). This indication is given by a 1-bit or 2-bit UL / DL association (per pair), as follows: 2 bits: 00 (DL only), 01 (UL only), 10 (applicable to both UL and DL) and 11 (reserved), and 1 bit: 0 (DL only) and 1 (applicable to both UL and DL).

[0095] An example table can be seen below (for only two pairs). [Table 2]

[0096] It should be understood that in some embodiments, the operation of the processes described above may be performed in a UE106 including a processor, communication interface, antenna port, radio, etc., and / or in a base station (e.g., gNB)102 including a processor, communication interface, antenna port, radio, etc., in order to implement those processes described above.

Thus, the processes taught by the above description can be executed by program code, such as machine-executable instructions, which cause a machine to perform specific functions. In this context, “machine” can be a machine that translates intermediate (or “abstract”) instructions into processor-specific instructions (e.g., an “abstract execution environment” such as a “virtual machine” (e.g., a Java Virtual Machine), an interpreter, a common language runtime, a high-level language virtual machine, etc.), and / or an electronic circuit (e.g., a “logic circuit” implemented with transistors) located on a semiconductor chip designed to execute instructions, such as a general-purpose processor and / or a dedicated processor. The processes taught by the above description may also be executed (in place of or in combination with a machine) by electronic circuits designed to execute those processes (or parts thereof) without executing program code.

[0140] For example, the operations of the embodiments described above may be stored as instructions on a non-temporary computer-readable medium for execution by a computer (e.g., a UE). The present invention also relates to a device for performing the operations described herein.

Program code may also be downloaded from a remote computer (e.g., a server) to a requesting computer (e.g., a client) by data signals embodied in a propagation medium (e.g., via a communication link (e.g., a network connection)).

[0143] The above-described "modes for carrying out the invention" are presented in terms of algorithms and symbolic representations of operations on data bits within computer memory. These descriptions and representations of algorithms are tools used by those skilled in the art to most effectively communicate the essence of the work to others skilled in the art. An algorithm, as used herein, is also generally considered to be a self-consistent sequence of operations that produces a desired result. These operations require the physical manipulation of physical quantities. While not usually necessary, these quantities take the form of electrical or magnetic signals that can be stored, transferred, combined, compared, and otherwise manipulated. For reasons of general use, it has proven convenient in some cases to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, etc.

[0144] However, it should be noted that all of these terms, and similar terms, are associated with appropriate physical quantities and are merely convenient labels applied to those quantities. Unless otherwise specifically stated, as is evident from the above explanation, any explanation using terms such as “select,” “determine,” “receive,” “form,” “group,” “aggregate,” “generate,” “delete,” or similar terms will be understood to refer to the operations and processes of a computer system or similar electronic computing device that manipulate data represented as physical (electronic) quantities in the registers or memory of the computer system to convert it into other data similarly represented as physical quantities in the computer system memory or registers, or in other such information storage devices, transmitting devices, or display devices.

[0145] The processes and representations presented herein are not specifically related to any particular computer or other device. Various general-purpose systems can be used with programs following the teachings herein, or it may be advantageous to construct more specialized devices for performing the operations described.
