[0033] Phase Tracking Reference Signal (PTRS) is used to facilitate receiver estimation of phase noise in New Radio (NR). For example, transmissions between a UE and a base station may exhibit phase noise. For the uplink (UL) physical uplink shared channel (PUSCH), PTRS can be configured with up to 2 ports. PTRS is associated with a demodulation reference signal (DMRS) port through a network (NW) indication. PTRS is transmitted in the same mode as DMRS.

[0034] The association of DMRS with a PTRS port is indicated by the "PTRS-DMRS Association" field in the Downlink Control Information (DCI) format 0_1 / 0_2. The "PTRS-DMRS Association" field is 0 or 2 bits.

[0035] When a single SRS resource set is configured with "nonCodebook" or "Codebook", the PTRS-DMRS association can be as follows Figure 1 and / or Figure 2 As indicated. Figure 1 An example PTRS-DMRS association map 100 is shown according to some embodiments. Figure 2 Another example PTRS-DMRS association map 200 is shown according to some embodiments.

[0036] According to some embodiments, the PTRS-DMRS association mapping 100 may indicate a mapping of a value to a DMRS port. Specifically, the network may provide the value to the UE via the base station to indicate a PTRS-DMRS association for the UE. The PTRS-DMRS association mapping 100 may indicate a PTRS-DMRS association or a second PTRS-DMRS association for UL PTRS port 0. The UE may receive the value from the base station and determine the DMRS port to be associated with the PTRS for the UE. For example, the value 0 may indicate a first scheduled DMRS port, as indicated in the PTRS-DMRS association mapping 100. Upon receiving the value 0, the UE may determine that the PTRS for the UE will be associated with the first scheduled DMRS port.

[0037] According to some embodiments, the PTRS-DMRS association mapping 200 may indicate a mapping of a value to a DMRS port. Specifically, the network may provide the most significant bit (MSB) and the least significant bit (LSB) to the UE via the base station to indicate the PTRS-DMRS association for the UE. The PTRS-DMRS association mapping 200 may indicate a PTRS-DMRS association or a second PTRS-DMRS association for UL PTRS ports 0 and 1. The UE may receive the MSB and LSB from the base station. In some embodiments, the MSB and LSB may be received as part of a single value. The UE may determine the DMRS port to be associated with the PTRS for the UE based on the MSB and LSB. For example, an MSB value of 0 may indicate a first DMRS port that shares PTRS port 0, as indicated in the PTRS-DMRS association mapping 200. An LSB value of 0 may indicate a first DMRS port that shares PTRS port 1. Upon receiving a value of 0, the UE may determine that the PTRS for the UE will be associated with the indicated DMRS port.

[0038] For non-codebook based PUSCH, DMRS to PTRS port association, for each non-codebook based sounding reference signal (SRS)-resource, the NW Radio Resource Control (RRC) configures the “ptrs-PortIndex.” The association is determined based on the “SRS Resource Indicator Field.”

[0039] For codebook-based PUSCH, DMRS to PTRS port association, the association is determined based on the "Precoding Information and Number of Layers" field. For PUSCH based on the "Fully Coherent and Partially Coherent and Incoherent" codebook, only 1 port PTRS can be configured. For PUSCH based on the "Partially Coherent and Incoherent" or "Incoherent" codebook, PUSCH antenna ports 1000 and 1002 in the indicated TPMI share PT-RS port 0, and PUSCH antenna ports 1001 and 1003 in the indicated TPMI share PT-RS port 1.

[0040] In Release 17 (Rel-17), for multiple transmission and reception point (TRP) PUSCH, an independent SRS resource set / SRS resource indicator (SRI) / transmission precoding matrix index (TPMI) can be indicated. For maxRank less than or equal to 2, a 2-bit PT-RS association with DMRS is used to jointly provide an indication for each TRP. The most significant bit (MSB) and the least significant bit (LSB) indicate the association between the PTRS port and the DMRS port for the two TRPs, respectively. For maxRank greater than 2, a second phase tracking reference signal (PT-RS) is introduced to the DMRS association field to provide an indication for the second TRP.

[0041] For Release 18 (Rel-18) NR, which will start in 2022, in the approved work item description (WID) (i.e., RP-213598), for the multiple-input multiple-output (MIMO) evolution for both downlink and uplink, it was agreed to consider supporting 8Tx UL operation. A new antenna architecture has been agreed in the recent RAN1#109 meeting. This new antenna architecture requires different phase noise handling and therefore requires PTRS enhancement.

[0042] 5. Study and, if justified, specify UL DMRS, SRS, SRI and TPMI (including codebook) enhancements to enable 8-transmission (Tx) UL operation to support 4 and more layers per UE in the UL targeting Customer Premises Equipment (CPE) / Fixed Wireless Access (FWA) / Vehicles / Industrial Equipment. NOTE: Potential limitations to the scope of this target (including coherence assumptions, full / non-full power modes) will be identified as part of the study.

[0043] The methods described herein address PTRS enhancements for 8Tx UL operation. UE capability reporting enhancements. NW configuration enhancements. Non-codebook PTRS port indexing.

[0044] Antenna architecture

[0045] PTRS design relies on assumptions about the antenna architecture, i.e., how much independent phase noise needs to be tracked from the transmitter. For example, depending on the number of antennas and the arrangement of the antennas, different PTRS methods can be implemented. The antennas can have the same or different phase noise based on the arrangement, and PTRS can be used to determine the phase noise for each of the antennas with different phase noise.

[0046] In the recent RAN1#109 meeting, the following antenna architecture was agreed. For example, the architecture described in the following paragraphs may be used in a UE (such as UE 1300 ( Fig.13The PTRS configuration for a UE may depend on which of these architectures has been implemented in the UE.

[0047] Figure 3 An example antenna architecture 300 according to some embodiments is shown. Specifically, the antenna architecture 300 may show an arrangement of antennas and / or antenna panels that may be implemented within a UE. Each square in the illustrated antenna architecture 300 may represent an antenna, where each antenna may have antenna elements exhibiting two different polarizations. Thus, one antenna may provide two Tx UL operations and may support two layers.

[0048] The first antenna architecture may be referred to as "NonCoherent". In a non-coherent antenna architecture, the antennas may each have different phase noise sources. Therefore, since each of the antennas has a different phase noise source, each antenna may have a phase noise that is measured to determine the phase noise of each antenna. Non-coherent coherence as mentioned herein may refer to a situation where the antennas of the UE do not have coherence, the phase error will be determined separately for each of the antennas, and / or the antennas have eight different phase noise sources. Non-coherent coherence may be referred to as non-coherent coherence and may be referred to in the configuration via a non-coherent indication.

[0049] The second antenna architecture may be referred to as “Full Coherent.” In a fully coherent antenna architecture, all antennas may have the same phase noise source. The phase noise source may depend on the position of the antenna in the antenna architecture.

[0050] Antenna architecture 300 shows an example first antenna arrangement 302 that can be fully coherent. As can be seen from the illustrated first antenna arrangement 302, the antennas of the first antenna arrangement 302 can be positioned adjacent to each other to form a square. The first antenna arrangement 302 can be referred to as a 1-a antenna arrangement.

[0051] Additionally, antenna architecture 300 illustrates an example second antenna arrangement 304 that may be fully coherent. As can be seen from the illustrated second antenna arrangement 304, the antennas of the second antenna arrangement 304 may be positioned adjacent to each other to form a line. The second antenna arrangement 304 may be referred to as a 1-b antenna arrangement.

[0052] The positions of the antennas in the first antenna arrangement 302 and the second antenna arrangement 304, which are positioned adjacent to each other, may result in the presence of a single phase noise source. Therefore, since the first antenna arrangement 302 and the second antenna arrangement 304 have a single phase noise source, the antenna arrangement may be fully coherent. Full coherence as mentioned herein may refer to the situation where all antennas of the UE have coherence, the phase errors of all antennas may be determined together, all antennas have the same phase source error, and / or the arrangement of antennas. Full coherence may be referred to as full coherence and may be referred to via a full coherence indication in a configuration.

[0053] The third antenna architecture may be referred to as "Partial Coherent 2". The Partial Coherent 2 antenna architecture may have 2 antenna panels (antenna groups), each antenna panel having 4 antenna elements. The Partial Coherent 2 antenna architecture may be coherent within each antenna panel, i.e., one phase noise, and may be incoherent, i.e., different phase noise, on different antenna panels.

[0054] Antenna architecture 300 illustrates an example third antenna arrangement 306 that may be partially coherent 2. As can be seen from the illustrated third antenna arrangement 306, first antenna 308 and second antenna 310 may be positioned adjacent to each other, and third antenna 312 and fourth antenna 314 may be positioned adjacent to each other. However, first antenna 308 and second antenna 310 may be separated from third antenna 312 and fourth antenna 314 by distance 326. Third antenna arrangement 306 may resemble a square with a spacing between the first group of antennas (including first antenna 308 and second antenna 310) and the second group of antennas (including third antenna 312 and fourth antenna 314). Third antenna arrangement 306 may be referred to as a 2-a antenna arrangement.

[0055] The antenna architecture 300 shows an example fourth antenna arrangement 316 that can be partially coherent 2. As can be seen from the fourth antenna arrangement 316, the first antenna 318 and the second antenna 320 can be positioned adjacent to each other, and the third antenna 322 and the fourth antenna 324 can be positioned adjacent to each other. However, the first antenna 318 and the second antenna 320 can be separated from the third antenna 322 and the fourth antenna 324 by a distance 328. The fourth antenna arrangement 316 can be similar to a line with a spacing between the first group of antennas (including the first antenna 318 and the second antenna 320) and the second group of antennas (including the third antenna 322 and the fourth antenna 324). The fourth antenna arrangement 316 can be referred to as a 2-b antenna arrangement.

[0056] The positions of the antennas in the third antenna arrangement 306 and the fourth antenna arrangement 316 may have two phase noise sources. For example, the first antenna 308 and the second antenna 310 positioned adjacent to each other may have a first phase noise source of the third antenna arrangement 306. The third antenna 312 and the fourth antenna 314 positioned adjacent to each other may have a second phase noise source of the third antenna arrangement 306, which may be different from the first phase noise source based on the separation of the first group of antennas from the second group of antennas. The first antenna 318 and the second antenna 320 positioned adjacent to each other may have a first phase noise source of the fourth antenna arrangement 316. The third antenna 322 and the fourth antenna 324 positioned adjacent to each other may have a second phase noise source of the fourth antenna arrangement 316, which may be different from the first phase noise source based on the separation of the first group of antennas from the second group of antennas. Since the third antenna arrangement 306 and the fourth antenna arrangement 316 have two phase noise sources, the antenna arrangements may be partially coherent 2. As referred to herein, partial coherence 2 coherence may refer to a situation where an antenna of a UE has coherence of two adjacent groups of antennas, a phase error of an antenna can be determined for two adjacent groups of antennas, an antenna has two separate phase noise sources, and / or an arrangement of antennas. Partial coherence 2 coherence may be referred to as first partial coherence and may be referred to in a configuration via a first partial coherence indication.

[0057] The fourth antenna architecture may be referred to as "Partial Coherent 4". The Partial Coherent 4 antenna architecture may have 4 antenna panels (antenna groups), each antenna panel having 2 antenna elements. Partial Coherent 4 may be coherent within each antenna panel, i.e., one phase noise, and may be incoherent, i.e., different phase noise, on different antenna panels.

[0058] Antenna architecture 300 shows an example fifth antenna arrangement 330 that can be partially coherent 4. As can be seen from the fifth antenna arrangement 330, all antennas can be separated from each other. Specifically, the first antenna 332 can be separated from the second antenna by a distance 340 in the first direction. In addition, the third antenna 336 can be separated from the fourth antenna 338 by a distance 340 in the first direction. The first antenna 332 can be separated from the third antenna 336 by a distance 342 in the second direction, the second direction being perpendicular to the first direction. The second antenna 334 can be separated from the fourth antenna 338 by a distance 342 in the second direction. The fifth antenna arrangement 330 can resemble a square with the distances separating the antennas. The fifth antenna arrangement 330 can be referred to as a 3-a antenna arrangement.

[0059] Antenna architecture 300 shows an example sixth antenna arrangement 344 that can be partially coherent 4. As can be seen from the sixth antenna arrangement 344, all antennas can be separated from each other. Specifically, the first antenna 346 can be separated from the second antenna 348 by a distance 354 in one direction. The second antenna 348 can be separated from the third antenna 350 by a distance 354 in the direction. The third antenna 350 can be separated from the fourth antenna 352 by a distance 354 in the direction. The sixth antenna arrangement 344 can be similar to a line with a distance separating the antennas. The sixth antenna arrangement 344 can be referred to as a 3-b antenna arrangement.

[0060] The positions of the antennas in the fifth antenna arrangement 330 and the sixth antenna arrangement 344 may have four phase noise sources. For example, each of the first antenna 332, the second antenna 334, the third antenna 336, and the fourth antenna 338 may present different phase noise sources due to the spacing between the antennas, resulting in four phase noise sources for the fifth antenna arrangement 330. Each of the first antenna 346, the second antenna 348, the third antenna 350, and the fourth antenna 352 may present different phase noise sources due to the spacing between the antennas, resulting in four phase noise sources for the sixth antenna arrangement 344. Since the fifth antenna arrangement 330 and the sixth antenna arrangement 344 have four phase noise sources, the antenna arrangement may be partially coherent 4. As mentioned herein, partially coherent 4 coherence may refer to the situation where the antenna of the UE has the coherence of a single antenna, the phase error of the antenna can be determined for each of the antennas, the antenna has four separate phase noise sources, and / or the arrangement of the antenna. Partial coherence 4 coherence may be referred to as second partial coherence, and may be referred to via a second partial coherence indication in the configuration.

[0061] UE Capability Report

[0062] As part of configuring PTRS for a UE, the network may utilize the characteristics of the UE to determine the appropriate configuration for the UE. Since different UEs may have different characteristics, it is beneficial for the UE to report the characteristics of the UE to the network so that the network can determine the appropriate configuration for the UE. The UE may report these characteristics in a UE capability report transmitted from the UE to the base station of the network.

[0063] Figure 4 An example signaling diagram 400 related to PTRS configuration according to some embodiments is shown. Specifically, the signaling diagram 400 shows example transmissions that may be exchanged between a UE 402 and a base station 404. The UE 402 may include a UE 1300 ( Fig.13 ) features. Base station 404 may include gNB 1400 ( Fig.14 )'s features.

[0064] The base station 404 may transmit a UE capability request 406 to the UE 402. The UE capability request 406 may request the UE to report the UE capabilities of the UE 402.

[0065] UE 402 may receive and identify a UE capability request 406 received from base station 404. UE 402 may determine that UE capability request 406 is requesting UE 402 to report UE capabilities of UE 402. Based on UE capability request 406, UE 402 may generate UE capability report message 408. UE capability report message 408 may include a UE capability report. UE capability report message 408 may include an indication of one or more characteristics of UE 402, as further described throughout this disclosure. UE 402 may transmit UE capability report message 408 to base station 404.

[0066] The base station 404 may receive and identify the UE capability report message 408. The base station 404 may determine characteristics of the UE 402 based on the UE capability report message 408. Based on the determined characteristics of the UE 402, the base station 404 may determine a PTRS configuration for the UE 402. The base station 404 may generate a PTRS and PUSCH operation configuration message 410 indicating the PTRS configuration for the UE 402, as further described throughout this disclosure. The base station 404 may transmit the PTRS and PUSCH operation configuration message 410 to the UE 402.

[0067] The UE 402 may receive and identify the PTRS and PUSCH operation configuration message 410 received from the base station 404. The UE 402 may be configured according to the configuration indicated in the PTRS and PUSCH operation configuration message 410.

[0068] Although signaling diagram 400 shows some example transmissions that may be transmitted between UE 402 and base station 404 in the illustrated embodiment, it should be understood that in other embodiments, these transmissions may be different. For example, in other embodiments, one or more of the transmissions shown may be omitted from the process, and / or one or more additional transmissions may be included in the process.

[0069] Figure 5 Another example signaling diagram 500 related to PTRS configuration according to some embodiments is shown. Specifically, the signaling diagram 500 shows example transmissions that may be exchanged between a UE 502 and a base station 504. The UE 502 may include a UE 1300 ( Fig.13 ) features. The base station 504 may include a gNB 1400 ( Fig.14 )'s features.

[0070] The base station 504 may transmit a UE capability request 506 to the UE 502. The UE capability request 506 may request the UE to report the UE capabilities of the UE 502.

[0071] The UE 502 may receive and identify a UE capability request 506 received from the base station 504. The UE 502 may determine that the UE capability request 506 is requesting the UE 502 to report the UE capabilities of the UE 502. Based on the UE capability request 506, the UE 502 may generate a UE capability report message 508. The UE capability report message 508 may include a UE capability report. The UE capability report message 508 may include an indication of one or more characteristics of the UE 502, as further described throughout this disclosure. The UE 502 may transmit the UE capability report message 508 to the base station 504.

[0072] The base station 504 may receive and identify the UE capability report message 508 received from the UE 502. Based on the UE capability report message 508, the base station 504 may determine the Tx configuration for the UE 502. The base station 504 may generate a Tx configuration message 510. The Tx configuration message 510 may include an indication of the Tx configuration for the UE 502. The base station 504 may transmit the Tx configuration message 510 to the UE 502.

[0073] The UE 502 may receive and identify a Tx configuration message 510 received from the base station 504. The UE 502 may determine a Tx configuration for the UE 502 based on the Tx configuration message 510. Based on the Tx configuration, the UE 502 may determine which coherence the UE 502 supports for the Tx configuration. The UE 502 may generate a coherence indication message 512 indicating one or more coherences supported by the UE 502 for the Tx configuration. The UE 502 may transmit the coherence indication message 512 to the base station 504.

[0074] The base station 504 may receive and identify the coherence indication message 512 received from the UE 502. The base station 504 may determine the PTRS configuration for the UE 502 based on the information within the UE capability report message 508 and / or the information within the coherence indication message 512. For example, the base station 504 may determine the PTRS configuration for the UE 502 based on the characteristics of the UE 502 determined from the UE capability report message 508 and / or the one or more coherences supported by the UE 502 for the Tx configuration indicated in the coherence indication message 512. The base station 504 may generate a PTRS and PUSCH operation configuration message 514 indicating the PTRS configuration for the UE 502, as further described throughout this disclosure. The base station 504 may transmit the PTRS and PUSCH operation configuration message 514 to the UE 502.

[0075] The UE 502 may receive and identify the PTRS and PUSCH operation configuration message 514 received from the base station 504. The UE 502 may be configured according to the configuration indicated in the PTRS and PUSCH operation configuration message 514.

[0076] Although signaling diagram 500 shows some example transmissions that may be transmitted between UE 502 and base station 504 in the illustrated embodiment, it should be understood that in other embodiments, these transmissions may be different. For example, in other embodiments, one or more of the transmissions shown may be omitted from the process and / or one or more additional transmissions may be included in the process. In addition, although Tx configuration message 510 and coherence indication message 512 are shown as separate messages, in other embodiments, Tx configuration message 510 and / or coherence indication message 512 or features thereof may be part of the PTRS and PUSCH operation configuration.

[0077] To support 8Tx operation of the UE, one or more transmissions within the signaling diagram 400 and / or the signaling diagram 500 may be modified from conventional transmissions. For example, in some embodiments, a UE capability report message (such as the UE capability report message 408 ( Figure 4 ) and / or UE capability report message 508 ( Figure 5 )) can be modified from the traditional UE capability report message to support 8Tx operation. The UE capability report message can indicate the characteristics of the UE, which can be used to determine the PTRS configuration for the UE to support 8Tx operation. The following are some methods for UE capability reporting, which indicate that the characteristics can be included in the UE capability report message.

[0078] Method 1.1: For non-codebook based PUSCH operation, the UE implicitly reports the number of Tx by reporting that the UE supports non-codebook based PUSCH operation and / or the maximum number of non-codebook SRS resources. For example, in the first method for UE capability reporting, the UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication that the UE supports non-codebook based PUSCH operation and / or an indication of the maximum number of SRS resources for non-codebook operation of the UE. The UE may support up to eight SRS resources. In addition, the UE may support up to eight Tx channels. A base station (such as base station 404( Figure 4 ) and / or base station 504 ( Figure 5 )) may determine, based on the maximum number of SRS resources for which the UE supports non-codebook based PUSCH operation and / or non-codebook operation as indicated by the UE capability report message, that the UE (such as UE 402( Figure 4 ) and / or UE 502( Figure 5 ))The number of Tx channels.

[0079] In some embodiments of the first method, the UE capability report message may also include an indication of whether the SRS resources are to be configured within an SRS resource set or may be divided between multiple SRS resource sets. In alternative 1: According to the TRP, all non-codebook SRS resources must be configured in the same SRS resource set. For example, the UE capability report message may indicate that all non-codebook resources will be configured in the same SRS resource set in alternative 1 according to the TRP. In alternative 2: According to the TRP, all non-codebook SRS resources may be configured in multiple SRS resource sets. For example, the UE capability report message may indicate that all non-codebook SRS resources may be configured in multiple SRS resource sets in alternative 2 according to the TRP.

[0080] Method 1.2: For codebook-based PUSCH operation, the UE implicitly reports the number of Tx by reporting that the UE supports codebook-based PUSCH operation and / or the maximum number of SRS ports supported by the UE. For example, in the second method for UE capability reporting, the UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication that the UE supports codebook-based PUSCH operation and / or an indication of the maximum number of SRS ports supported by the UE. A base station (such as base station 404 and / or base station 504) may determine the number of Tx channels of a UE (such as UE 402 and / or UE 502) based on the UE supporting codebook-based PUSCH operation and / or the maximum number of SRS ports supported by the UE as indicated by the UE capability message. For example, if the UE capability message indicates that the UE supports eight SRS ports, the base station may determine that the UE supports up to eight Tx channels. In a codebook-based PUSCH, all SRS ports may be transmitted in one resource.

[0081] In some embodiments of the second method, the UE capability report message may also include an indication of whether the SRS port is to be configured within one SRS resource or may be divided between multiple SRS resources. In alternative 1: According to the TRP, all SRS ports must be configured in one SRS resource. For example, the UE capability report message may indicate that all SRS ports are to be configured in one SRS resource in alternative 1 according to the TRP. In alternative 2: According to the TRP, all SRS ports may be configured in multiple SRS resources. For example, the UE capability report message may indicate that all SRS ports may be configured in multiple SRS resources according to the TRP.

[0082] Method 1.3: The UE may report the number of PTRS ports supported by the UE. The maximum value may be 4 or 8. For example, in a third method for UE capability reporting, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication of the number of PTRS ports required by the UE. In an embodiment, the maximum value of the number of PTRS ports required by the UE indicated by the UE capability report message may be 4 or 8.

[0083] This can be used to infer the UE antenna architecture. For example, a base station (such as base station 404 and / or base station 504) can determine the UE antenna architecture for a UE (such as UE 402 and / or UE 502). Four PTRS ports imply "partial coherence 4". For example, the base station can determine that the UE has partial coherence 4 coherence (such as indicated by the fifth antenna arrangement 330 ( Figure 3 ) and / or the sixth antenna arrangement 344 ( Figure 3 )). Therefore, the base station can determine that the UE presents four independent phase noise sources. Two PTRS ports implies "partial coherence 2". For example, the base station can determine that the UE has partial coherence 2 coherence (such as indicated by the third antenna arrangement 306 ( Figure 3 ) and / or the fourth antenna arrangement 316 ( Figure 3 )). Therefore, the base station can determine that the UE has two independent phase noise sources. The base station can determine that the UE has full coherence (such as the first antenna 302 ( Figure 3 ) and / or the second antenna arrangement 304 ( Figure 3 )). Therefore, the base station can determine that the UE presents a single phase noise source.

[0084] Method 1.4: For codebook-based PUSCH operation, the UE may also report the supported coherence. For example, in a fourth method for UE capability reporting, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication of one or more coherences supported by the UE. In addition to "incoherent" and "full coherence", the UE may also report different "partial coherences", i.e., "partial coherence 2" or "partial coherence 4". For example, a UE capability report message may indicate that a UE (such as UE 402 and / or UE 502) supports incoherent coherence, full coherence coherence, partial coherence 2 coherence, and / or partial coherence 4 coherence. The UE is allowed to report different "partial coherences" only if it reports that the UE supports 8Tx UL operation. For example, in some embodiments, the UE capability report message may include an indication of how many Tx UL channels the UE supports. When the indication of how many Tx UL channels the UE supports is eight Tx channels, the UE capability report message may include an indication of partial coherence 2 coherence or partial coherence 4 coherence.

[0085] In some embodiments, the UE capability report message may include an indication of the antenna arrangement of the UE. When the indication is "full coherence", the UE may report whether the UE supports "1-a" (2x2) or "1-b" (1x4). For example, in the case of indicating full coherence, the UE capability report message may include an indication of whether the UE's antenna arrangement is in antenna arrangement 1-a (such as the first antenna arrangement 302) or in antenna arrangement 1-b (such as the second antenna arrangement 304). For "partial coherence 2", the UE may report whether the UE supports "2-a" (vertical stacking) or "2-b" (horizontal stacking). For example, in the case of indicating partial coherence 2 coherence, the UE capability report message may include an indication of whether the UE's antenna arrangement is in antenna arrangement 2-a (such as the third antenna arrangement 306) or in antenna arrangement 2-b (such as the fourth antenna arrangement 316). For "partial coherence 4", the UE may report whether the UE supports "3-a" (2x2) or "3-b" (1x4). For example, in the case of indicating partial coherence 4 coherence, the UE capability report message may include an indication of whether the UE's antenna arrangement is in antenna arrangement 3-a (such as the fifth antenna arrangement 330) or in antenna arrangement 3-b (such as the sixth antenna arrangement 344).

[0086] Method 1.5: For codebook-based PUSCH operation, if the UE reports that it supports 8Tx operation and the supported coherence, the UE may further report to the NW when a fewer number of Txs are configured, for example, what the supported coherences are. For example, the UE capability report message 508 may include an indication that the UE (such as UE 402 and / or UE 502) supports eight Tx channels and / or an indication of one or more coherences supported by the UE. A base station (such as base station 404 and / or base station 504) may determine the number of Tx channels to configure the UE based on the indication that the UE supports eight Tx channels and / or an indication of one or more coherences supported by the UE. The base station may provide an indication of the number of Tx channels to be configured for UE 502. In some embodiments, the NW may include an indication of the number of Tx channels to be configured for UE 502 in a Tx configuration message (such as Tx configuration message 510 ( Figure 5 )) indicates the number of Tx channels. In the event that the base station indicates that less than eight Tx channels will be configured for the UE, the UE may determine one or more coherences supported by the UE for the number of Tx channels to be configured. The UE may provide an indication of one or more coherences supported by the UE based on the number of Tx channels to be configured. In some embodiments, the coherence indication message (such as coherence indication message 512 ( Figure 5 )) indicates one or more supported coherences.

[0087] For 8Tx, if the UE supports "partial coherence 4", when the NW configures 2Tx, it indicates whether the UE supports "incoherence" or "full coherence". For example, the UE may indicate that the UE supports eight Tx channels and partial coherence 4 coherence for these eight Tx channels. In the case where the base station indicates that the UE will be configured with two Tx channels, the UE may indicate that the UE supports incoherent coherence or full coherence coherence. Therefore, in these cases, the coherence indication message may include an indication of incoherent coherence or full coherence coherence. When the NW configures 4Tx, it indicates whether the UE supports "incoherence" or "partial coherence". For example, the UE may indicate that the UE supports eight Tx channels and partial coherence 4 coherence for these eight Tx channels. In the case where the base station indicates that the UE will be configured with four Tx channels, in these cases, the UE may indicate that the UE supports incoherent coherence or partial coherence coherence. Therefore, in these cases, the coherence indication message may include an indication of incoherent coherence or partial coherence coherence.

[0088] For 8Tx, if the UE supports "partial coherence 2", when the NW configures 2Tx, it indicates whether the UE supports "incoherence" or "full coherence". For example, the UE may indicate that the UE supports eight Tx channels and partial coherence 2 coherence for these eight Tx channels. In the case where the base station indicates that the UE will be configured with two Tx channels, the UE may indicate that the UE supports incoherent coherence or full coherence coherence. Therefore, in these cases, the coherence indication message may include an indication of incoherent coherence or full coherence coherence. When the NW configures 4Tx, it indicates whether the UE supports "partial coherence" or "full coherence". For example, the UE may indicate that the UE supports eight Tx channels and partial coherence 2 coherence for these eight Tx channels. In the case where the base station indicates that the UE will be configured with four Tx channels, in these cases, the UE may indicate that the UE supports partial coherence coherence or full coherence coherence.

[0089] Network Configuration

[0090] To support eight Tx operations of the UE, a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 ( Figure 4 ) and / or PTRS and PUSCH operation configuration message 514 ( Figure 5 )) can be modified from the legacy PTRS and PUSCH operation configuration message. The PTRS and PUSCH operation configuration message can indicate the PTRS configuration for the UE supporting eight Tx operations. In addition, the configuration can depend on whether codebook or non-codebook usage is configured.

[0091] Method 2.1: When the NW configures the UE with 8Tx codebook PUSCH operation, the NW may further configure the coherence. For example, a Tx configuration message (such as Tx configuration message 510 ( Figure 5 )) and / or PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 ( Figure 4 ) and / or PTRS and PUSCH operation configuration message 514 ( Figure 5 )) may indicate to a UE (such as UE 402 ( Figure 4 ) and / or UE 502( Figure 5 )) will be configured with eight Tx codebook PUSCH operation and / or the UE will be configured with coherence in the first network configuration method.

[0092] The following configurations are allowed. For example, in some embodiments, the PTRS and PUSCH operation configuration message may indicate the following configurations. If the UE reports that the UE supports "full coherent" 8Tx operation, the NW may configure "full coherent", "partial coherent 2", "partial coherent 4", or "non-coherent". For example, if the UE reports that the UE supports "full coherent" 8Tx operation in a UE capability report message (such as UE capability report message 408 ( Figure 4 ) and / or UE capability report message 508 ( Figure 5 )) and / or in a coherence indication message (such as coherence indication message 512 ( Figure 5 )) indicates that the UE supports full coherent eight Tx operations, then the base station (such as base station 404 ( Figure 4 ) and / or base station 504 ( Figure 5 )) may indicate in the PTRS and PUSCH operation configuration messages that the UE will be configured with full coherence, partial coherence 2 coherence, partial coherence 4 coherence or non-coherence coherence.

[0093] If the UE reports that the UE supports "partial coherence 2" 8Tx operation, the NW may configure "partial coherence 2", "partial coherence 4" or "non-coherence". For example, if the UE indicates in the UE capability report message and / or the coherence indication message that the UE supports partial coherence 2 8Tx operation, the base station may indicate in the PTRS and PUSCH operation configuration message that the UE will be configured with partial coherence 2 coherence, partial coherence 4 coherence or non-coherence coherence.

[0094] If the UE reports that the UE supports "partial coherence 4" 8Tx operation, the NW may configure "partial coherence 4" or "non-coherence". For example, if the UE indicates in the UE capability report message and / or the coherence indication message that the UE supports partial coherence 4 8Tx operation, the base station may indicate in the PTRS and PUSCH operation configuration message that the UE will be configured with partial coherence 4 coherence or non-coherence coherence.

[0095] If the UE reports that the UE supports "non-coherent" 8Tx operation, the NW can only configure "non-coherent". For example, if the UE indicates in the UE capability report message and / or the coherence indication message that the UE supports non-coherent 8Tx operation, the base station can indicate in the PTRS and PUSCH operation configuration message that the UE will be configured with non-coherent coherence.

[0096] Method 2.2: When the UE supports 8Tx operation, but the NW configures the UE with 2Tx codebook PUSCH operation, the following coherence configuration is allowed. For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication that the UE supports eight Tx operation in the second network configuration method. In addition, in the second network configuration method, the network may configure the UE (such as UE 402 and / or UE 502) with two Tx codebook PUSCH operation by including an indication that the UE will be configured with two Tx codebook PUSCH operation in a Tx configuration message (such as Tx configuration message 510) and / or a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514). In these cases, the following coherence configuration can be achieved.

[0097] If the UE supports "full coherence" 8Tx operation, the NW may configure "full coherence" or "non-coherence". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports full coherence for eight Tx operations. In these cases, the network may determine to configure the UE for full coherence or non-coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for full coherence or non-coherence.

[0098] If the UE supports "non-coherent" 8Tx operation, the NW may only configure "non-coherent". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports non-coherent coherence for eight Tx operations. In these cases, the network may determine that the UE is configured for non-coherent coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for non-coherent coherence.

[0099] If the UE supports 8Tx operation of "partial coherence 2" or "partial coherence 4", the NW may configure "full coherence" or "incoherence". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports partial coherence 2 coherence or partial coherence 4 coherence for eight Tx operations. In these cases, the network may determine to configure the UE for full coherence coherence or incoherence coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for full coherence coherence or incoherence coherence. "Full coherence" may be subject to additional UE capability reporting.

[0100] Method 2.3: When the UE supports 8Tx operation, but the NW configures the UE with 4Tx codebook PUSCH operation, the following coherence configuration is allowed. For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) may include an indication that the UE (such as UE 402 and / or UE 502) supports eight Tx operation in the third network configuration method. In addition, in the third network configuration method, the network may configure the UE with four Tx codebook PUSCH operation by including an indication that the UE will be configured with four Tx codebook PUSCH operation in a Tx configuration message (such as Tx configuration message 510) and / or a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514). In these cases, the following coherence configuration can be achieved.

[0101] If the UE supports "full coherence" 8Tx operation, the NW may configure "full coherence" or "partial coherence" or "incoherence". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports full coherence for eight Tx operations. In these cases, the network may determine to configure the UE for full coherence, partial coherence, or incoherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for full coherence, partial coherence, or incoherence.

[0102] If the UE supports "non-coherent" 8Tx operation, the NW may only configure "non-coherent". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports non-coherent coherence for eight Tx operations. In these cases, the network may determine that the UE is configured for non-coherent coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for non-coherent coherence.

[0103] If the UE supports 8Tx operation with "partial coherence 2", the NW may configure "full coherence" or "partial coherence" or "incoherence". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports partial coherence 2 coherence for eight Tx operations. In these cases, the network may determine to configure the UE for full coherence coherence, partial coherence coherence, or incoherence coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for full coherence coherence, partial coherence coherence, or incoherence coherence. "Full coherence" may be subject to additional UE capability reporting.

[0104] If the UE supports 8Tx operation with "partial coherence 4", the NW may configure "partial coherence" or "incoherence". For example, a UE capability report message (such as UE capability report message 408 and / or UE capability report message 508) and / or a coherence indication message (such as coherence indication message 512) may include an indication that the UE supports partial coherence 4 coherence for eight Tx operations. In these cases, the network may determine to configure the UE for partial coherence coherence or incoherence coherence, in which case a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured for partial coherence coherence or incoherence coherence. "Partial coherence" may be subject to additional UE capability reporting.

[0105] Method 2.4: When the NW configures 8Tx operation, the NW may configure more than 2 PTRS ports. The maximum number of PTRS ports may be 4. For example, a Tx configuration message (such as Tx configuration message 510) and / or a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that a UE (such as UE 402 and / or UE 502) is to be configured with eight Tx operations and more than two PTRS ports. The maximum number of configured PTRS ports for a UE that may be indicated in the Tx configuration message and / or the PTRS and PUSCH operation configuration message may be four PTRS ports.

[0106] In some embodiments, the Tx configuration message and / or the PTRS and PUSCH operation configuration message may include a PTRS-uplinkconfig information element. Figure 6 An example PTRS-uplinkconfig information element 600 is shown according to some embodiments. As shown in the illustrated embodiment, the PTRS-uplinkconfig information element 600 may have a maximum number of port values ​​602 of four, as shown by the enumerated n1, n2, n3, and n4. Although in the illustrated embodiment, the PTRS-uplinkconfig information element 600 includes other elements (such as frequencyDensity, timeDensity, resourceElementOffset, and ptrs-Power), it should be understood that in other embodiments, the PTRS-uplinkconfig information element 600 may include different elements with a maximum number of port values ​​602.

[0107] The NW configures 8Tx operation by configuring the SRS resource set SRS-ResourceSet with a "codebook" usage of 8-port SRS resources, or configuring the SRS resource set with a "non-codebook" usage of 8 concentrated SRS resources, each SRS resource containing a single port. For example, in some cases, the Tx configuration message and / or the PTRS and PUSCH operation configuration message may include an indication that the SRS resource set is configured with a codebook usage of eight-port SRS resources. In other cases, the Tx configuration message and / or the PTRS and PUSCH operation message may include an indication that the SRS resource set will be configured with a non-codebook usage of eight concentrated SRS resources, each of which may include a single port.

[0108] The NW may configure a maximum of 4 ports PTRS only under one or a combination of the following conditions. The NW configures 8Tx operations, and / or for codebook operations, the NW configures a coherence of "non-coherent" or "partial coherence 4" [or "partial coherence 2"]. For example, the Tx configuration message and / or the PTRS and PUSCH operation configuration message may include an indication that the UE will be configured with eight Tx operations and / or for codebook operations, non-coherent coherence, partial coherence 4 coherence, or partial coherence 2 coherence will be configured for the UE. In addition, the Tx configuration message and / or the PTRS and PUSCH operation configuration message will be configured with a maximum of four ports PTRS, such as configured for four PTRS ports, two PTRS ports, or one PTRS port.

[0109] Non-codebook PTRS port index

[0110] To support eight Tx operations for a UE, certain non-codebook PTRS port indexing may be implemented. For example, a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 ( Figure 4 ) and / or PTRS and PUSCH operation configuration message 514 ( Figure 5 )) can be modified from the legacy PTRS and PUSCH operation configuration messages to support certain non-codebook PTRS port index configurations.

[0111] For non-codebook, when SRS-ResourceSet is configured with "non-codebook" usage. For example, UE (such as UE 402 ( Figure 4 ) and / or UE 502( Figure 5 )) may be configured with non-codebook usage. The UE may be configured with non-codebook usage via radio power control (RRC) for one or two SRS resource sets. For each SRS-Resource in the SRS-ResourceSet, the NW may configure a PTRS port index for a PTRS to DMRS association indication. For example, a PTRS and PUSCH operation configuration message (such as a PTRS and PUSCH operation configuration message 410 and / or a PTRS and PUSCH operation configuration message 514) may include an indication that the UE will be configured with a PTRS port for each SRS-Resource in the SRS-ResourceSet. The PTRS to DMRS association indication may be determined based on the PTRS port for each SRS-Resource. For each SRS-Resource, the NW may only configure one of a maximum of two PTRS ports. For example, the PTRS and PUSCH operation configuration message may include an indication that one of a maximum of two PTRS ports will be configured.

[0112] Figure 7 An example SRS resource information element 700 is shown according to some embodiments. The SRS resource information element 700 includes a PTRS port index element 702 that may be included in a PTRS and PUSCH operation configuration message for configuration of a PTRS port. The PTRS port index element 702 indicates that there are two port indexes that may be configured as indicated by n0 and n1.

[0113] Method 3.1: For each SRS resource in the SRS resource set that is configured with "non-codebook" usage, the NW may configure a PTRS port index from one of up to four PTRS ports. For example, a PTRS and PUSCH operation configuration message (such as the PTRS and PUSCH operation configuration message 410 and / or the PTRS and PUSCH operation configuration message 514) may include an indication of one or more SRS resources that will be configured in the SRS resource set in the first method of non-codebook PRS port indexing. In addition, the PTRS and PUSCH operation may indicate which SRS resources will be configured with non-codebook usage and a PTRS port index from four PTRS ports.

[0114] The NW is allowed to select one of up to four PTRS ports only under one or a combination of the following conditions. The NW configures 8Tx operation. For non-codebook operation, the UE operates in a coherence mode of "incoherent". For non-codebook operation, the UE operates in a coherence mode of "partial coherence 4". [For non-codebook operation, the UE operates in a coherence mode of "partial coherence 2"]. For example, if the PTRS and PUSCH configuration message also includes an indication that the UE will be configured with eight Tx operation, an indication that the UE will be configured with a coherence mode of incoherent coherence, an indication that the UE will be configured with a coherence mode of partial coherence 4 coherence, an indication that the UE will be configured with a coherence mode of partial coherence 2 coherence, or some combination thereof, the PTRS and PUSCH operation configuration message may include one of the four PTRS ports.

[0115] Method 3.2: When the NW configures 8Tx non-codebook operation, for each SRS resource in the SRS resource set configured with "non-codebook" usage, the following restrictions may be considered for the configuration of the PTRS port index. For example, a Tx configuration message (such as Tx configuration message 510 ( Figure 5 )) and / or a PTRS and PUSCH operation configuration message (such as PTRS and PUSCH operation configuration message 410 and / or PTRS and PUSCH operation configuration message 514) may include an indication that the UE is to be configured with eight Tx non-codebook operations. With respect to the configuration of the PTRS port index for each SRS resource in an SRS resource set configured with non-codebook usage, the following features may be considered.

[0116] For "full coherence" operation, all SRS resources must be configured with the same PTRS port index, or only one SRS resource may be configured with a PTRS port index. For example, the PTRS and PUSCH operation configuration message may include an indication of the SRS resource for which the PTRS port index is to be configured for full coherence operation.

[0117] For "partial coherence 2" operation, up to 2 different PTRS port indices may be configured for different SRS resources. For example, the PTRS and PUSCH operation configuration message may include an indication that up to two different PTRS port indices will be configured for different SRS resources for partial coherence 2 coherence operation. For each PTRS port index, it should be configured to be associated with 4 SRS resources or only one SRS resource.

Fig.13 The block diagram of UE 1300 is intended to show a high-level view of certain of the components of UE 1300. However, some of the components shown may be omitted, additional components may be present, and different arrangements of the components shown may occur in other implementations.

[0177] Components of UE 1300 may be coupled to various other components via one or more interconnects 1332, which may represent any type of interface, input / output, bus (local, system, or extended), transmission line, trace, optical connection, etc. that allows various circuit components (on a common or different chip or chipset) to interact with each other.

[0178] The processor 1304 may include processor circuits such as, for example, a baseband processor circuit (BB) 1304A, a central processor unit circuit (CPU) 1304B, and a graphics processor unit circuit (GPU) 1304C. The processor 1304 may include any type of circuit or processor circuit that executes or otherwise operates computer-executable instructions (such as program codes, software modules, or functional processes from the memory / storage device 1312) to cause the UE 1300 to perform operations as described herein.

[0179] In some embodiments, the baseband processor circuit 1304A can access the communication protocol stack 1336 in the memory / storage device 1312 to communicate through a 3GPP compatible network. Generally speaking, the baseband processor circuit 1304A can access the communication protocol stack to: perform user plane functions at the PHY layer, MAC layer, RLC layer, PDCP layer, SDAP layer, and PDU layer; and perform control plane functions at the PHY layer, MAC layer, RLC layer, PDCP layer, RRC layer, and non-access layer.

The RF interface circuit 1308 may include various elements arranged in a transmit path or a receive path. These elements may include, for example, switches, mixers, amplifiers, filters, synthesizer circuits, control circuits, etc.

[0183] In the receive path, the RFEM may receive the radiated signal from the air interface via antenna 1326 and proceed to filter and amplify the signal (using a low noise amplifier). The signal may be provided to a transceiver's receiver, which down-converts the RF signal to a baseband signal that is provided to a baseband processor of processor 1304.

[0184] In the transmit path, the transmitter of the transceiver up-converts the baseband signal received from the baseband processor and provides the RF signal to the RFEM. The RFEM may amplify the RF signal through a power amplifier before the signal is radiated across the air interface via the antenna 1326.

[0185] In various embodiments, the RF interface circuit 1308 can be configured to send / receive signals in a manner compatible with NR access technology.

[0186] Antenna 1326 may include antenna elements to convert electrical signals into radio waves to travel through the air and to convert received radio waves into electrical signals. These antenna elements may be arranged into one or more antenna panels. Antenna 1326 may have an antenna panel that is omnidirectional, directional, or a combination thereof to achieve beamforming and multiple input / multiple output communications. Antenna 1326 may include a microstrip antenna, a printed antenna manufactured on the surface of one or more printed circuit boards, a patch antenna, a phased array antenna, etc. Antenna 1326 may have one or more panels that are designed for a specific frequency band including a band in FR1 or FR2.

The output device circuit may include any number or combination of audio or visual displays, including in particular one or more simple visual outputs / indicators (e.g., binary state indicators, such as light emitting diodes (LEDs)) and multi-character visual outputs, or more complex outputs, such as display devices or touch screens (e.g., liquid crystal displays (LCDs), LED displays, quantum dot displays, projectors, etc.), where the output of characters, graphics, multimedia objects, etc. is generated or produced by the operation of the UE 1300.

[0188] Sensors 1320 may include devices, modules, or subsystems that are designed to detect events or changes in their environment and communicate information about the detected events (sensor data) to some other device, module, subsystem, etc. Examples of such sensors include, among others: an inertial measurement unit including an accelerometer, gyroscope, or magnetometer; a microelectromechanical system or nanoelectromechanical system including a 3-axis accelerometer, 3-axis gyroscope, or magnetometer; a liquid level sensor; a flow sensor; a temperature sensor (e.g., a thermistor); a pressure sensor; a barometric pressure sensor; a gravity meter; an altimeter; an image capture device (e.g., a camera or a lensless aperture); a light detection and ranging sensor; a proximity sensor (e.g., an infrared radiation detector, etc.); a depth sensor; an ambient light sensor; an ultrasonic transceiver; a microphone or other similar audio capture device; and the like.

[0189] The driver circuit 1322 may include software and hardware elements for controlling specific devices embedded in, attached to, or otherwise communicatively coupled to the UE 1300. The driver circuit 1322 may include various drivers to allow other components to interact with or control various input / output (I / O) devices that may be present in or connected to the UE 1300. For example, the driver circuit 1322 may include: a display driver for controlling and allowing access to a display device, a touch screen driver for controlling and allowing access to a touch screen interface, a sensor driver for obtaining sensor readings of the sensor 1320 and controlling and allowing access to the sensor 1320, a driver for obtaining an actuator position of an electromechanical component or controlling and allowing access to an electromechanical component, a camera driver for controlling and allowing access to an embedded image capture device, and an audio driver for controlling and allowing access to one or more audio devices.

[0190] The PMIC 1324 may manage the power provided to various components of the UE 1300. Specifically, with respect to the processor 1304, the PMIC 1324 may control power source selection, voltage scaling, battery charging, or DC-DC conversion.

[0191] In some embodiments, the PMIC 1324 may control or otherwise be part of various power saving mechanisms of the UE 1300. For example, if the platform UE is in the RRC_Connected state, in which the platform is still connected to the RAN node because it expects to receive traffic soon, then after a period of inactivity, the platform may enter a state known as discontinuous reception mode (DRX). During this state, the UE 1300 may be powered off for short time intervals, thereby saving power. If there is no data traffic activity for an extended period of time, the UE 1300 may transition to the RRC_Idle state, in which the UE is disconnected from the network and no operations such as channel quality feedback, handovers, etc. are performed. The UE 1300 enters a very low power state and performs paging, in which the platform again periodically wakes up to listen to the network and then powers off again. The UE 1300 may not receive data in this state; in order to receive data, the platform must transition back to the RRC_Connected state. Additional power saving modes may prevent the device from using the network for periods exceeding the paging interval (from a few seconds to a few hours). During this time, the device is completely unable to connect to the network and can be completely powered off. Any data transmitted during this time will be significantly delayed, and it is assumed that the delay is acceptable.

[0192] The battery 1328 can power the UE 1300, but in some examples, the UE 1300 can be installed to be deployed in a fixed location and can have a power source coupled to the power grid. The battery 1328 can be a lithium-ion battery, a metal-air battery such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, etc. In some specific implementations, such as in vehicle-based applications, the battery 1328 can be a typical lead-acid car battery.

[0194] The components of gNB 1400 may be coupled to various other components via one or more interconnects 1428.
