[0001] This description relates to random-access procedures for non-terrestrial networks.BACKGROUND
[0002] Wireless communication networks provide integrated communication platforms and telecommunication services to wireless user devices. Example telecommunication services include telephony, data (e.g., voice, audio, and / or video data) , messaging, and / or other services. The wireless communication networks have wireless access nodes that exchange wireless signals with the wireless user devices using one or more wireless network protocols, such as protocols described in various telecommunication standards promulgated by the European Telecommunications Standards Institute (ETSI) Third Generation Partnership Project (3GPP) . The wireless communication networks facilitate mobile broadband service using technologies such as orthogonal frequency-division multiple access (OFDMA) , multiple-input multiple output (MIMO) , advanced channel coding, massive MIMO, beamforming, and / or other features.SUMMARY

[0033] For non-terrestrial networks (NTNs) , a user equipment (UE) communicates with a satellite that acts as an access node (e.g., base station) . For NTN communication, the UE establishes downlink / uplink timings with the satellite by performing a random access procedure (e.g., 2-step or 4-step procedure) . For a 4-step random access procedure, the UE may be configured to receive message 4 (Msg4) that confirms access for the UE from the satellite using physical downlink shared channel (PDSCH) . The UE may be configured to then transmit a hybrid automatic repeat request acknowledgment (HARQ-ACK) for the Msg4 to the satellite using physical uplink control channel (PUCCH) .
[0034] In NTN, due to power constraints of the satellite and the relatively large distance between the UE and the satellite, non-terrestrial communications may have lower signal quality, higher path loss, and greater latency, compared to terrestrial communications. To address these issues, NTN coverage enhancement schemes can be introduced for both uplink (UL) and downlink (DL) . With respect to the random access procedure, the DL coverage enhancement can be implemented by a repetition of PDSCH transmission of Msg4 (e.g., also referred to as PDSCH repetition of Msg4) , while the UL coverage enhancement is implemented by a repetition of PUCCH transmission of Msg4 HARQ-ACK (e.g., also referred to as PUCCH repetition of Msg4 HARQ-ACK) . The UE may be configured to support at least one UL coverage enhancement or DL coverage enhancement for NTN. Accordingly, techniques for jointly indicating a capability of the UE and the request associated with both UL coverage enhancement and DL coverage enhancement for NTN may be needed.
[0035] In accordance with aspects of the present disclosure, a UE may be configured to indicate a capability of the UE and a request for at least PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4 to an access node. The UE may determine that at least one of one or more RSRP-based conditions is met based on one or more (e.g., same or different) reference signal receive power (RSRP) threshold values associated with UL coverage enhancement or DL coverage enhancement. The UE may responsively select information (e.g., LCID or a reserved bit of MAC subheader) indicating the capability of the UE and / or the request for at least PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4. The UE may then transmit the selected information to the access node. In this manner, proper configurations can be facilitated by a network for UL coverage enhancement and / or DL coverage enhancement for NTN.
[0036] FIG. 1 illustrates an example wireless network 100, according to some implementations. The wireless network 100 includes a UE 102 and a base station 104, which are connected via one or more channels 106A, 106B across an air interface 108. The UE 102 and base station 104 communicate using a system that supports controls for managing the access of the UE 102 to a network via the base station 104.
[0037] In some implementations, the wireless network 100 is a Standalone (SA) network, e.g., that incorporates fifth generation (5G) New Radio (NR) . In some other implementations, the wireless network 100 is a non-standalone (NSA) network that incorporates Long Term Evolution (LTE) and 5G NR. In these implementations, the wireless network 100 may be an Evolved Universal Terrestrial Radio Access (E-UTRA) NR dual connectivity (EN-DC) network, or an NR-EUTRA dual connectivity (NE-DC) network. Furthermore, wireless networks implementing one or more other types of communication standards are possible, including future 3GPP systems (e.g., sixth generation “6G” ) , Institute of Electrical and Electronics Engineers (IEEE) 702.11 technology, or the like. While aspects may be described herein using terminology commonly associated with 5G NR, aspects of the present disclosure can be applied to other systems, such as systems subsequent to 5G (e.g., 6G) .
[0038] In the wireless network 100, the UE 102 and any other UE in the system may be, for example, any of a laptop computer, smartphone, tablet computer, machine-type device (such as smart meters or specialized devices for healthcare) , intelligent transportation system, or any other wireless device. In the wireless network 100, the base station 104 provides the UE 102 network connectivity to a broader network (not shown) . This UE 102 connectivity is provided via the air interface 108 in a base station service area provided by the base station 104. In some implementations, such a broader network may be a wide area network operated by a cellular network provider, or may be the Internet. Each base station service area associated with the base station 104 is supported by one or more antennas integrated with the base station 104. The service areas can be divided into a number of sectors associated with one or more particular antennas. Such sectors may be physically associated with one or more fixed antennas or may be assigned to a physical area with one or more tunable antennas or antenna settings adjustable in a beamforming process used to direct a signal to a particular sector.
[0039] The UE 102 includes control circuitry 110 coupled with transmit circuitry 112 and receive circuitry 114. The transmit circuitry 112 and receive circuitry 114 may each be coupled with one or more antennas. The control circuitry 110 may include application-specific circuitry, baseband circuitry, or any of various combinations thereof. The transmit circuitry 112 and receive circuitry 114 may be adapted to transmit and receive data, respectively, and may include radio frequency (RF) circuitry and / or front-end module (FEM) circuitry.
[0040] In various implementations, aspects of the transmit circuitry 112, receive circuitry 114, and / or control circuitry 110 may be integrated in various ways to implement the operations described herein. The control circuitry 110 may be adapted or configured to perform various operations, such as those described elsewhere in this disclosure related to a UE. For example, the control circuitry 110 can determine a measurement period for UE-initiated / event-driven beam measurement reporting based on a periodicity of reference signals associated with a first / second beam, a number of samples used for measurements of the first / second beam, and so on.
[0041] The transmit circuitry 112 can perform various operations described herein. For example, the transmit circuitry 112 can transmit a PUCCH to request uplink resources for a UE-initiated / event-driven beam measurement report. Additionally, the transmit circuitry 112 may transmit using a plurality of multiplexed uplink physical channels. The plurality of uplink physical channels may be multiplexed, e.g., according to time division multiplexing (TDM) or frequency division multiplexing (FDM) , and in some implementations, along with carrier aggregation (CA) . The transmit circuitry 112 may be configured to receive block data from the control circuitry 110 for transmission on the air interface 108.
[0042] The receive circuitry 114 can perform various operations described herein. For example, the receive circuitry 114 can receive one or more reference signals (such as an SSB) via a first beam and a second beam during a measurement period that depends on a reference signal periodicity of the first beam and / or the second beam. Additionally, the receive circuitry 114 may receive a plurality of multiplexed downlink physical channels from the air interface 108 and relay the physical channels to the control circuitry 110. The plurality of downlink physical channels may be multiplexed, e.g., according to TDM or FDM, e.g., along with CA. The transmit circuitry 112 and the receive circuitry 114 may transmit and receive, respectively, both control data and content data (e.g., messages, images, video, and the like) structured within data blocks that are carried by the physical channels.
[0043] FIG. 1 also illustrates the base station 104. In some implementations, the base station 104 may be a 5G radio access network (RAN) , a next generation RAN, a E-UTRAN, a non-terrestrial cell, or a legacy RAN, such as a UTRAN. As used herein, the term “5G RAN” or the like may refer to the base station 104 that operates in an NR wireless network 100, and the term “E-UTRAN” or the like may refer to a base station 104 that operates in an LTE wireless network 100. The UE 102 utilizes connections (or channels) 106A, 106B, each of which includes a physical communications interface or layer.
[0044] The base station 104 circuitry may include control circuitry 116 coupled (directly or indirectly) with transmit circuitry 118 and / or receive circuitry 120. The transmit circuitry 118 and receive circuitry 120 may each be coupled (directly or indirectly) with one or more antennas that may be used to enable communications via the air interface 108. The transmit circuitry 118 and receive circuitry 120 may be adapted to transmit and receive data, respectively, addressed to any UE connected to the base station 104. The receive circuitry 120 may receive a plurality of uplink physical channels from one or more UEs, including the UE 102.
[0045] In FIG. 1, the one or more channels 106A, 106B are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as an LTE protocol, advanced LTE (LTE-A) protocol, LTE-based access to unlicensed spectrum (LTE-U) , NR protocol, NR-based access to unlicensed spectrum (NR-U) protocol, and / or any other communications protocol (s) . In some implementations, the UE 102 may directly exchange communication data via a ProSe interface. The ProSe interface may alternatively be referred to as a sidelink interface and may include one or more logical channels, including but not limited to a physical sidelink control channel (PSCCH) , a physical sidelink discovery channel (PSDCH) , and a physical sidelink broadcast channel (PSBCH) .
[0046] In some implementations, a 4-step random access procedure may be performed by a UE (e.g., the UE 102) and an access node (e.g., the base station 104 or satellite) . For example, the 4-step random access procedure may be a contention-based random access procedure (CBRA) . The UE may initiate the 4-step random access procedure by transmitting a preamble in message 1 (Msg1) using a physical random access channel (PRACH) . Upon detection of the preamble, the access node may respond with a message 2 (Msg2) that includes a random access response (RAR) using a physical downlink control channel (PDCCH) . The RAR may include a UL grant for a message 3 (Msg3) . The UE may transmit the Msg3 using a physical uplink shared channel (PUSCH) . The base station may transmit a message 4 (Msg4) to indicate a contention resolution using a PDSCH. The UE may acknowledge the Msg4 with a HARQ-ACK message using a PUCCH.
[0047] In some implementations, PUCCH repetition of Msg4 HARQ-ACK is used for UL coverage enhancement for NTN. In this context, UL coverage enhancement and PUCCH repetition of Msg4 HARQ-ACK described herein may be interchangeable. LCID codepoints (e.g., values of LCID) in a MAC subheader for an uplink shared channel (UL-SCH) may be used to indicate a capability of a UE and / or a request for PUCCH repetition of Msg4 HARQ-ACK to an access node (e.g., the base station 104 or satellite) , as defined in 3GPP TS 38.321 Release 18. For a UE capable of PUCCH repetition of Msg4 HARQ-ACK, a MAC entity of the UE may use the LCID codepoints for PUCCH repetition of Msg4 HARQ-ACK if the parameter numberOfMsg4HARQ-ACK-Repetitions is configured and the parameter rsrp-ThresholdMsg4HARQ-ACK is not configured, or if both parameters are configured and the reference signal received power (RSRP) of the downlink pathloss reference is less than the parameter rsrp-ThresholdMsg4HARQ-ACK.
[0048] A MAC entity of the UE may use at least one of the LCID codepoints for PUCCH repetition of Msg4 HARQ-ACK only if a network (e.g., via an access node) indicates support for the PUCCH repetition of Msg4 HARQ-ACK. If PUCCH repetition of Msg4 HARQ-ACK is supported, the UE may set an LCID extension (LX) field to 1 to indicate the use of extended LCID space and select one of six LCID codepoints for PUCCH repetition of Msg4 HARQ-ACK. Otherwise, a reserved (R) field may be present instead of the LX field (e.g., the LX field is not present) , or the UE may set the LX field to 0.
[0049] Two LCID codepoints 0 and 52 for common control channel (CCCH) of size 48 bits and 64 bits are defined for normal UE (e.g., a UE except for an (e) RedCap UE) and two LCID codepoints 35 and 36 for CCCH of size 48 bits and 64 bits reduced capability (RedCap) UE, as shown in Table 1. Table 1 is used when the LX field is not present or is set to 0. TABLE 1
[0050] Two LCID codepoints 0 and 1 for CCCH of size 48 bits and 64 bits are defined for each of enhanced RedCap (eRedCap) UE, and six LCID codepoints 2-7 for CCCH of size 48 bits and 64 bits for PUCCH repetition of Msg4 HARQ-ACK are defined for normal UE, RedCap UE, and eRedCap UE, as shown in Table 2. Table 2 is used when the LX field is set to 1. TABLE 2
[0051] If a UE sets an LCID field to one of the six LCID codepoints 2-7 shown in Table 2, the UE may indicate its capability to support PUCCH repetition of Msg4 HARQ-ACK and a request for PUCCH repetition of Msg4 HARQ-ACK. A UE may transmit one of the six LCID codepoints in the LCID field of a MAC subheader using a MAC protocol data unit (PDU) to a network. A network that receives one of the six LCID codepoints from a UE may configure PUCCH repetition of Msg4 HARQ-ACK for the UE.
[0052] In some implementations, link-level enhancements for frequency range 1 (FR1) and system-level enhancements for FR1 and frequency range 2 (FR2) is used for DL coverage enhancement for NTN. For example, the link-level enhancements may be implemented by at least PDCCH repetition of at least common search space (CSS) , PDSCH repetition of Msg4, or PDSCH repetition of system information block (SIB1) within 20 (millisecond) ms duration. For example, the system-level enhancements may be implemented by at least supporting extended periodicity (e.g., maximum 160 ms) of the half frames with synchronization signal (SS) / PBCH blocks assumed by a UE during initial access. The techniques for DL coverage enhancements described herein may allow dynamic and flexible power sharing between satellite beams or different satellite beam patterns / sizes (e.g., wide or narrow) across the satellite footprint.
[0053] If DL coverage enhancement is introduced, a UE may support PDSCH repetition of Msg4. In this context, DL coverage enhancement and PDSCH repetition of Msg4 described herein may be interchangeable. In this scenario, UEs may have different capabilities. For example, there may be UEs that only support UL coverage enhancement, UEs that only support DL coverage enhancement, or UEs that support both UL and DL coverage enhancements. Furthermore, a UE may not meet both conditions for UL and DL coverage enhancements at the same time due to different RSRP threshold values for UL and DL coverage enhancements. For example, if two RSRP threshold values for UL and DL coverage enhancements are configured by a network or preconfigured to a UE, the UE may only meet one of the two conditions for UL and DL coverage enhancements. If a single RSRP threshold value for both UL and DL coverage enhancements is (pre) configured to a UE, the UE may meet two conditions for UL and DL coverage enhancements at the same time. In a scenario where a relationship between RSRP threshold values for UL and DL coverage enhancements is not defined, various implementations for joint indication of a capability of a UE and a request for PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4 may be considered, depending on the (pre) configured RSRP threshold values.
[0054] FIG. 2 illustrates an example diagram 200 of LCID codepoints for a joint indication of a capability of a UE and a request for PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, according to some implementations. In some implementations, six LCID codepoints [x, y] may be defined for indicating a capability of a UE (e.g., the UE 102) and a request for PDSCH repetition of Msg4, and additional six codepoints [y+1, z] may be defined for jointly indicating a capability of a UE and a request for both PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, as shown in FIG. 2. For example, LCID codepoints 8-13 for reserved LCID values in Table 2 may be used for the six LCID codepoints [x, y] , and LCID codepoints 14-19 for reserved LCID values in Table 2 may be used for the six LCID codepoints [y+1, z] . Among the six LCID codepoints [x, y] , a set of two LCID codepoints may be defined for CCCH of size 48 bits and 64 bits for each of normal UE, RedCap UE, and eRedCap UE. Similarly, among the six LCID codepoints [y+1, z] , a set of two LCID codepoints may be defined for CCCH of size 48 bits and 64 bits for each of normal UE, RedCap UE, and eRedCap UE.
[0055] If a UE sets an LCID field to one of the six LCID codepoints [x, y] , the UE may indicate its capability to support PDSCH repetition of Msg4 and a request for PDSCH repetition of Msg4. A UE may transmit one of the six LCID codepoints [x, y] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a MAC PDU including one of the six LCID codepoints [x, y] from a UE, a network may configure PDSCH repetition of Msg4 for the UE.
[0056] If a UE sets an LCID field to one of the six LCID codepoints [y+1, z] , the UE may indicate its capability to support both PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4 and a request for both PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4. A UE may transmit one of the six LCID codepoints [y+1, z] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a MAC PDU including one of the six LCID codepoints [y+1, z] from a UE, a network may configure PDSCH repetition of Msg4 for the UE.
[0057] In some implementations, a single RSRP threshold value for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may be (pre) configured to a UE. In this scenario, a single RSRP-based condition for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may be defined. The single RSRP-based condition may be met if an RSRP of a downlink pathloss reference is less than the single RSRP threshold value. If the single RSRP-based condition is met, a UE that is only capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] , and a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [y+1, z] .
[0058] In some implementations, two RSRP threshold values for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may be (pre) configured to a UE. In this scenario, two RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may be defined. Each RSRP-based condition may be met if an RSRP of a downlink pathloss reference is less than each RSRP threshold value, respectively.
[0059] In some implementations, the RSRP threshold value for the PUCCH repetition of Msg4 HARQ-ACK may be lower than the RSRP threshold value for the PDSCH repetition of Msg4. If both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [y+1, z] . A UE may transmit one of the six LCID codepoints [y+1, z] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a MAC PDU including one of the six LCID codepoints [y+1, z] , a network may determine that both RSRP-based conditions are met and configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE. If only the RSRP-based condition for PDSCH repetition of Msg4 is met, a UE capable of the PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] regardless of whether the UE is also capable of the PUCCH repetition of Msg4 HARQ-ACK.
[0060] In some implementations, the RSRP threshold value for the PUCCH repetition of Msg4 HARQ-ACK may be higher than the RSRP threshold value for the PDSCH repetition of Msg4. If both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [y+1, z] . A UE may transmit one of the six LCID codepoints [y+1, z] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a MAC PDU including one of the six LCID codepoints [y+1, z] , a UE may determine that both RSRP-based conditions are met and configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE. If only the RSRP-based condition for PUCCH repetition of Msg4 HARQ-ACK is met, a UE may set an LCID field to one of the six LCID codepoints 2-7 shown in Table 2, regardless of whether the UE is capable of PDSCH repetition of Msg4.
[0061] In some implementations, a UE may indicate a request for a repetition level for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4 based on that RSRP conditions are met. Two or more repetition levels may be defined. For example, two repetition levels may comprise a low repetition number of 2 and a high repetition number of 4. For another example, two repetition levels may comprise a low repetition number of 4 and a high repetition number of 8. In some implementations, additional LCID codepoints may be defined for finer indication of a request for a repetition level for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4. Six LCID codepoints for a low repetition number and six LCID codepoints for a high repetition number may be defined. A UE may set an LCID field of a MAC subheader to one of the six LCID codepoints for a low repetition number to indicate a request for the low repetition number for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4. A UE may set an LCID field of a MAC subheader to one of the six LCID codepoints for a high repetition number to indicate a request for the high repetition number for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4.
[0062] FIG. 3 illustrates an example diagram 300 of LCID codepoints for a joint indication of a capability of a UE and a request for PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, according to some implementations. In some implementations, PUCCH repetition of Msg4 HARQ-ACK may be configured for a UE (e.g., the UE 102) as conditionally mandatory for PDSCH repetition of Msg4. In such implementations, six LCID codepoints [x, y] may be defined for indicating a capability of a UE and a request for PDSCH repetition of Msg4, as shown in FIG. 3. Among the six LCID codepoints [x, y] , a set of two LCID codepoints may be defined for CCCH of size 48 bits and 64 bits for each of normal UE, RedCap UE, and eRedCap UE.
[0063] In some implementations, in case that a single RSRP threshold value for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is (pre) configured and a single RSRP-based condition for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is met, a UE capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] . In such implementations, one of the six LCID codepoints [x, y] may also imply a capability of the UE and a request for PUCCH repetition of Msg4 HARQ-ACK. As such, a UE may jointly indicate its capability and request for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 using one of the six LCID codepoints [x, y] . A UE may transmit one of the six LCID codepoints [x, y] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving one of the six LCID codepoints [x, y] from a UE, a network may configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE.
[0064] In some implementations, in case that a single RSRP threshold value for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is (pre) configured and a single RSRP-based condition for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is met, a UE that is only capable of PUCCH repetition of Msg4 HARQ-ACK may set an LCID field to one of the six LCID codepoints 2-7 shown in Table 2. A UE may transmit one of the six LCID codepoints 2-7 shown in Table 2 in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving one of the six LCID codepoints 2-7 shown in Table 2 from a UE, a network may determine that the UE does not support PDSCH repetition of Msg4. As such, the network may only configure PUCCH repetition of Msg4 HARQ-ACK for the UE.
[0065] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is lower than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] . In this scenario, a network may not be able to differentiate whether the UE requests PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 since the RSRP threshold value for PDSCH repetition of Msg4 is higher than the RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK. Accordingly, a network that receives one of the six LCID codepoints [x, y] from a UE may always configure PUCCH repetition of Msg4 HARQ-ACK for the UE by its implementation.
[0066] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is lower than an RSRP threshold value for PDSCH repetition of Msg4, and only the RSRP-based condition for PDSCH repetition of Msg4 is met, a UE capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] . In this scenario, a network may not be able to differentiate whether the UE requests PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 since the RSRP threshold value for PDSCH repetition of Msg4 is higher than the RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK. Accordingly, a network that receives one of the six LCID codepoints [x, y] from a UE may always configure PUCCH repetition of Msg4 for the UE by its implementation.
[0067] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is higher than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints [x, y] . In such implementations, one of the six LCID codepoints [x, y] may also imply a capability of the UE and a request for PUCCH repetition of Msg4 HARQ-ACK. As such, a UE may jointly indicate its capability and request for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4. A UE may transmit one of the six LCID codepoints [x, y] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving one of the six LCID codepoints [x, y] from a UE, a network may configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE.
[0068] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is higher than an RSRP threshold value for PDSCH repetition of Msg4, and only the RSRP-based condition for PUCCH repetition of Msg4 HARQ-ACK is met, a UE capable of PDSCH repetition of Msg4 may set an LCID field to one of the six LCID codepoints 2-7 shown in Table 2. A UE may transmit one of the six LCID codepoints 2-7 shown in Table 2 in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving one of the six LCID codepoints 2-7 shown in Table 2 from a UE, a network may configure PUCCH repetition of Msg4 HARQ-ACK for the UE.
[0069] FIG. 4 illustrates an example diagram 400 of a MAC subheader structure for a joint indication of a capability of a UE and a request for PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, according to some implementations. In some implementations, a reserved bit field (e.g., renamed to J field) in a MAC subheader may be used to indicate a capability of a UE (e.g., the UE 102) to support both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4, as shown in FIG. 4. In such implementations, six LCID codepoints [x, y] may be defined for indicating a request for PDSCH repetition of Msg4. Among the six LCID codepoints [x, y] , a set of two LCID codepoints may be defined for CCCH of size 48 bits and 64 bits for each of normal UE, RedCap UE, and eRedCap UE.
[0070] In some implementations, in case that a single RSRP threshold value for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is (pre) configured and a single RSRP-based condition for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is met, a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set a J field to 1 and set an LCID field to one of the six LCID codepoints [x, y] . A UE may transmit a value of 1 in the J field and one of the six LCID codepoints [x, y] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a value of 1 in the J field and one of the six LCID codepoints [x, y] from a UE, a network may configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE.
[0071] In some implementations, in case that a single RSRP threshold value for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is (pre) configured and a single RSRP-based condition for both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 is met, a UE that is only capable of either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 may set a J field to 0. In such implementations, an LCID codepoint may be set to one of the six LCID codepoints [x, y] or one of the six LCID codepoints 2-7 shown in Table 2, depending on the capability of the UE. In this scenario, a network that receives a value of 0 in the J field and one LCID codepoint from a UE may configure either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 for the UE based on the LCID codepoint reported by the UE.
[0072] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is lower than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set a J field to 1 and set an LCID field to one of the six LCID codepoints 2-7 shown in Table 2. A UE may transmit a value of 1 in the J field and one of the six LCID codepoints 2-7 shown in Table 2 in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a value of 1 in the J field and one of the six LCID codepoints 2-7 shown in Table 2 from a UE, a network may configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE.
[0073] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is lower than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE that is only capable of either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 may set a J field to 0. In such implementations, an LCID codepoint may be set to one of the six LCID codepoints [x, y] or one of the six LCID codepoints 2-7 shown in Table 2, depending on the capability of the UE. In this scenario, a network that receives a value of 0 in the J field and one LCID codepoint from a UE may configure either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 for the UE based on the LCID codepoint reported by the UE.
[0074] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is lower than an RSRP threshold value for PDSCH repetition of Msg4, and only the RSRP-based condition for PDSCH repetition of Msg4 is met, a UE capable of PDSCH repetition of Msg4 may set a J field to either 0 or 1 and set an LCID field to one of the six LCID codepoints [x, y] . In this scenario, a value of the J field may not affect a network’s determination of configuring PDSCH repetition of Msg4 for a UE. As such, a network that receives a value of 0 or 1 in the J field and one of the six LCID codepoints [x, y] from a UE may configure PDSCH repetition of Msg4 for the UE.
[0075] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is higher than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 may set a J field to 1 and set an LCID field to one of the six LCID codepoints [x, y] . A UE may transmit a value of 1 in the J field and one of the six LCID codepoints [x, y] in the LCID field of a MAC subheader using a MAC PDU to a network via a UL-SCH. Upon receiving a value of 1 in the J field and one of the six LCID codepoints [x, y] from a UE, a network may configure both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 for the UE.
[0076] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is higher than an RSRP threshold value for PDSCH repetition of Msg4, and both RSRP-based conditions for the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 are met, a UE that is only capable of either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 may set a J field to 0. In such implementations, an LCID codepoint may be set to one of the six LCID codepoints [x, y] or one of the six LCID codepoints 2-7 shown in Table 2, depending on the capability of the UE. In this scenario, a network that receives a value of 0 in the J field and one LCID codepoint from a UE may configure either PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4 for the UE based on the LCID codepoint reported by the UE.
[0077] In some implementations, in case that an RSRP threshold value for PUCCH repetition of Msg4 HARQ-ACK is higher than an RSRP threshold value for PDSCH repetition of Msg4, and only the RSRP-based condition for PUCCH repetition of Msg4 HARQ-ACK is met, a UE capable of PDSCH repetition of Msg4 may set a J field to either 0 or 1 and set an LCID field to one of the six LCID codepoints 2-7 shown in Table 2. In this scenario, a value of the J field may not affect a network’s determination of configuring PUCCH repetition of Msg4 HARQ-ACK for a UE. As such, a network that receives a value of 0 or 1 in the J field and one of the six LCID codepoints 2-7 shown in Table 2 from a UE may configure PUCCH repetition of Msg4 HARQ-ACK for the UE.
[0078] In some implementations, a reserved bit field (e.g., R field) in a MAC subheader may be used to indicate a request for a repetition level for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4 based on that RSRP conditions are met. A UE may set a value of a R field of a MAC subheader to 1 to indicate a request for the high repetition number for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4. A UE may set a value of a R field of a MAC subheader to 0 to indicate a request for a low repetition number for PUCCH repetition of Msg4 HARQ-ACK and / or PDSCH repetition of Msg4.
[0079] FIG. 5 illustrates a flowchart of an example method 500 for a joint indication of a capability of a UE and a request for PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, according to some implementations. For clarity of presentation, the example method 500 is described in the context of the preceding figures. For example, the method 500 can be performed by a UE (e.g., the UE 102) , or any suitable system, environment, software, hardware, or combination thereof. In some implementations, operations of the method 500 can be run in parallel, in combination, in loops, or in any order. The example method 500 shown in FIG. 5 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 5) , which can be performed in the order shown or in a different order.
[0080] In the method 500, at 505, the UE determines that at least one of one or more RSRP-based conditions is met based on one or more RSRP threshold values. In some implementations, the UE may receive a configuration that includes the one or more RSRP threshold values from an access node. In some implementations, the UE may be preconfigured with the one or more RSRP threshold values. In some implementations, the one or more RSRP threshold values may comprise an RSRP threshold associated with both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4. In such implementations, the UE may determine the at least one of the one or more RSRP-based conditions is met based on determining that an RSRP of a downlink pathloss reference is less than the RSRP threshold value.
[0081] In some implementations, the one or more RSRP threshold values may comprise a first RSRP threshold value associated with the PUCCH repetition of Msg4 HARQ-ACK and a second RSRP threshold value associated with the PDSCH repetition of Msg4. In some implementations, the first RSRP threshold value may be lower than the second RSRP threshold value. In such implementations, the UE may determine that at least one of the one or more RSRP-based conditions is met based on determining an RSRP of a downlink pathloss reference is less than both the first RSRP threshold value and the second RSRP threshold value or that the RSRP of downlink pathloss reference is less than the second RSRP threshold value only.
[0082] In some implementations, the first RSRP threshold value may be higher than the second RSRP threshold value. In some implementations, the UE may determine that at least one of the one or more RSRP-based conditions is met based on determining an RSRP of downlink pathloss reference is less than both the first RSRP threshold value and the second RSRP threshold value or that an RSRP of downlink pathloss reference is less than the first RSRP threshold value only.
[0083] At 510, the UE responsively selects an LCID codepoint indicating a capability of a UE to support at least one of PUCCH repetition of Msg4 HARQ-ACK or PDSCH repetition of Msg4. In some implementations, in case that the one or more RSRP threshold values comprise an RSRP threshold value associated with both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 and the UE determines that at least one of the one or more RSRP-based conditions is met, the LCID codepoint may be selected from six LCID codepoints for the PDSCH repetition of Msg4. In such implementations, the six LCID codepoints may indicate that the UE is capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4.
[0084] In some implementations, in case that the one or more RSRP threshold values comprise an RSRP threshold value associated with both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4 and the UE determines that at least one of the one or more RSRP-based conditions is met, the LCID codepoint may be selected from six LCID codepoints for the PUCCH repetition of Msg4 HARQ-ACK. In such implementations, the six LCID codepoints may indicate that the UE is capable of only the PUCCH repetition of Msg4 HARQ-ACK.
[0085] In some implementations, in case that the first RSRP threshold value associated with the PUCCH repetition of Msg4 HARQ-ACK is lower than the second RSRP threshold value associated with the PDSCH repetition of Msg4, and the UE determines that the at least one of the one or more RSRP-based conditions is met, the LCID codepoint may be selected from six LCID codepoints for the PDSCH repetition of Msg4. In such implementations, the six LCID codepoints may indicate that the UE requests at least one of the PUCCH repetition of Msg4 HARQ-ACK or the PDSCH repetition of Msg4.
[0086] In some implementations, in case that the first RSRP threshold value associated with the PUCCH repetition of Msg4 HARQ-ACK is higher than the second RSRP threshold value associated with the PDSCH repetition of Msg4 and the UE determines that an RSRP of downlink pathloss reference is less than both the first RSRP threshold value and the second RSRP threshold value, the LCID codepoint may be selected from six LCID codepoints for the PDSCH repetition of Msg4. In such implementations, the six LCID codepoints may indicate that the UE is capable of both the PUCCH repetition of Msg4 HARQ-ACK and the PDSCH repetition of Msg4.
[0087] In some implementations, in case that the first RSRP threshold value associated with the PUCCH repetition of Msg4 HARQ-ACK is higher than the second RSRP threshold value associated with the PDSCH repetition of Msg4 and the UE determines that an RSRP of downlink pathloss reference is less than the first RSRP threshold value only, the LCID codepoint may be selected from six LCID codepoints for the PUCCH repetition of Msg4 HARQ-ACK. In such implementations, the six LCID codepoints may indicate that the UE is capable of the PUCCH repetition of Msg4 HARQ-ACK.
[0088] At 515, the UE transmits the LCID codepoint in a MAC message to an access node. In some implementations, in case that the UE transmits the LCID codepoint selected from six LCID codepoints for the PDSCH repetition of Msg4, the UE may receive a first configuration associated with the PUCCH repetition of Msg4 HARQ-ACK and a second configuration associated with the PDSCH repetition of Msg4 from the access node. In some implementations, in case that the UE transmits the LCID codepoint selected from six LCID codepoints for the PUCCH repetition of Msg4 HARQ-ACK, the UE may receive a first configuration associated with the PUCCH repetition of Msg4 HARQ-ACK from the access node.
[0089] FIG. 6A illustrates a flowchart of an example method 600 for a joint indication of a capability of a UE and a request for both PUCCH repetition of Msg4 HARQ-ACK and PDSCH repetition of Msg4, according to some implementations. For clarity of presentation, the example method 600 is described in the context of the preceding figures. For example, the method 600 can be performed by a UE (e.g., the UE 102) , or any suitable system, environment, software, hardware, or combination thereof. In some implementations, operations of the method 600 can be run in parallel, in combination, in loops, or in any order. The example method 600 shown in FIG. 6A can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 6A) , which can be performed in the order shown or in a different order.
[0090] In the method 600, at 605, the UE determines that at least one of one or more RSRP-based conditions is met based on one or more RSRP threshold values. In some implementations, the UE may receive a configuration that includes the one or more RSRP threshold values from an access node. In some implementations, the UE may be preconfigured with the one or more RSRP threshold values.

[0185] Any of the foregoing examples can be combined with any other example (or combination of examples) , unless explicitly stated otherwise. The foregoing description of one or more implementations provides illustration and description, but is not intended to be exhaustive or to limit the scope of embodiments to the precise form disclosed. Modifications and variations are possible in light of the above teachings or may be acquired from practice of various embodiments.
[0186] Although the embodiments above have been described in considerable detail, numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the following claims be interpreted to embrace all such variations and modifications.
[0187] As described above, one aspect of the present technology may relate to the gathering and use of data available from specific and legitimate sources to allow for interaction with a second device for a data transfer. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to identify a specific person. Such personal information data can include demographic data, location-based data, online identifiers, telephone numbers, email addresses, home addresses, data or records relating to a user’s health or level of fitness (e.g., vital signs measurements, medication information, exercise information) , date of birth, or any other personal information.
[0188] The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to provide for secure data transfers occurring between a first device and a second device. The personal information data may further be utilized for identifying an account associated with the user from a service provider for completing a data transfer.
[0189] The present disclosure contemplates that those entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and / or privacy practices. In particular, such entities would be expected to implement and consistently apply privacy practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. Such information regarding the use of personal data should be prominent and easily accessible by users, and should be updated as the collection and / or use of data changes. Personal information from users should be collected for legitimate uses only. Further, such collection / sharing should occur only after receiving the consent of the users or other legitimate basis specified in applicable law. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and / or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations that may serve to impose a higher standard. For example, in the US, collection of or access to certain health data may be governed by federal and / or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA) ; whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly.
[0190] Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and / or software elements can be provided to prevent or block access to such personal information data. For example, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. For example, a user may “opt in” or “opt out” of having information associated with an account of the user stored on a user device and / or shared by the user device. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For example, a user may be notified upon downloading an application that their personal information data will be accessed and then reminded again just before personal information data is accessed by the application. In some instances, the user may be notified upon initiation of a data transfer of the device accessing information associated with the account of the user and / or the sharing of information associated with the account of the user with another device.
[0191] Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user’s privacy. De-identification may be facilitated, when appropriate, by removing identifiers, controlling the amount or specificity of data stored (e.g., collecting location data at city level rather than at an address level) , controlling how data is stored (e.g., aggregating data across users) , and / or other methods such as differential privacy.
[0192] Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users based on aggregated non-personal information data or a bare minimum amount of personal information, such as the content being handled only on the user’s device or other non-personal information available to the content delivery services.
