[0056] FIG. 3 illustrates a network device 300 in accordance with some embodiments. The network device 300 may be similar to and substantially interchangeable with base station 108 or a device of the core network 112 or external data network 120.
[0057] The network device 300 may include processors 304, RF interface circuitry 308 (if implemented as a base station) , core network (CN) interface circuitry 314, memory / storage circuitry 312, and antenna structure 326.
[0058] The components of the network device 300 may be coupled with various other components over one or more interconnects 328.
[0059] The processors 304, RF interface circuitry 308, memory / storage circuitry 312 (including communication protocol stack 310) , antenna structure 326, and interconnects 328 may be similar to like-named elements shown and described with respect to FIG. 2.
[0060] The processors 304 may include processor circuitry such as, for example, baseband processor circuitry (BB) 304A, central processor unit circuitry (CPU) 304B, and graphics processor unit circuitry (GPU) 304C. The processors 304 may include any type of circuitry or processor circuitry that executes or otherwise operates computer-executable instructions, such as program code, software modules, or functional processes from memory / storage circuitry 312 to cause the network device 300 to perform operations described herein. The processors 304 may also include interface circuitry 304D to communicatively couple the processor circuitry with one or more other components of the network device 300.
[0061] The CN interface circuitry 314 may provide connectivity to a core network, for example, a 5th Generation Core network (5GC) using a 5GC-compatible network interface protocol such as carrier Ethernet protocols, or some other suitable protocol. Network connectivity may be provided to / from the network device 300 via a fiber optic or wireless backhaul. The CN interface circuitry 314 may include one or more dedicated processors or FPGAs to communicate using one or more of the aforementioned protocols. In some implementations, the CN interface circuitry 314 may include multiple controllers to provide connectivity to other networks using the same or different protocols.
[0062] During operation, a UE can be triggered to generate and / or transmit a beam report to a base station. For example, the UE can be triggered to generate and / or transmit a beam report based on a signal quality of a current beam dropping below a threshold value, a signal quality of a neighbor beam exceeding a threshold value, a signal quality of a neighbor beam exceeding a signal quality of a current beam, or another configured beam report trigger. Once a beam report has been triggered, the UE may communicate with a base station for scheduling transmission of the beam report. However, communication with the base station for scheduling the transmission of the beam report can become an issue when the beam report is triggered while the UE is in a discontinuous reception (DRX) inactive state. Approaches described herein can address at least some of the issues presented when a beam report is triggered while the UE is in a DRX inactive state.
[0063] New radio (NR) multiple input multiple output (MIMO) enhancement may be implemented in networks. UE initiated beam report is one of the objectives in release 19 (R19) . For example, an objective may be to specify enhancement to facilitate UE-initiated / event-driven beam management for reducing overhead and / or latency, assuming the unified transmission configuration indicator (TCI) while leveraging (as much as possible) legacy channel state information (CSI) measurement and reporting configuration frameworks, targeting frequency range 2 (FR2) and serving transmit and receive point (sTRP) with intra-and inter-cell beam management. Uplink (UL) signaling content (s) (and procedure (s) as required) for UE-initiated / event-driven beam reporting facilitating fast beam switching may be considered. Further, UL signaling medium / container considering the UE-initiated / event-driven nature of the UL transmission, designed primarily for the purpose of beam reporting, may be considered.
[0064] UE initiated beam report may have certain features. A general framework for UE initiated beam report may include one or more of the following. A network (NW) may configure the measured reference signal (RS) and related report / event to the UE. For each report, the NW can configure to use which transmission scheme / special resource for the UE initiated beam report (UEI-BR) transmission. The UE may perform the measurement on the configured RS, and when the event / criteria is satisfied, the UE may initiate the beam report via the configured transmission scheme / or resource.
[0065] Systems may implement two UEI-BR transmission schemes. A first transmission scheme may be referred to as mode-A. For mode-A, the UE may transmit a first physical uplink control channel (PUCCH) (not PUCCH-scheduling request (SR) ) to request the resource for a second UL channel transmission which will carry the beam report. The UE may detect the downlink control information (DCI) which indicates a resource for a second UL channel to carry a beam report. A beam report may be transmitted in the second UL channel (i.e., physical uplink shared channel (PUSCH) channel) .
[0066] A second transmission scheme may be referred to as mode-B. For mode-B, the UE may transmit a first PUCCH (not PUCCH-SR) notifying a second UL channel to carry beam report. The UE may transmit the beam report in the second UL channel (type-1 configured grant (CG) PUSCH to carry the beam report) . The association between the first PUCCH channel and the second UL channel may be configured by radio resource control (RRC) .
[0067] FIG. 4 illustrates an example beam report initiation procedure 400 in accordance with some embodiments. For example, the procedure 400 illustrates an example procedure of performing beam measurements and triggering of beam report. The procedure may be performed by a UE, such as the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) .
[0068] The procedure 400 may include configuration of a beam measurement for a potential beam report in 402. For example, the UE may receive a configuration message from a base station that indicates a configuration for beam measurement, determine a configuration for beam measurement already configured, or another procedure for determining a configuration for performing beam measurements. In some instances, the configuration may indicate one or more RSs for performing beam measurements.
[0069] The procedure 400 may include performing a measurement on an RS in 404. For example, the UE may perform a measurement on an RS indicated by the configuration determined in 402. The measurement may include measuring a signal quality on the RS, such as a reference signal received power (RSRP) measurement, a channel quality measurement, an interference measurement, a signal to interference noise ratio (SINR) , or some combination thereof.
[0070] The procedure 400 may include a beam event evaluation in 406. For example, the UE may compare the values of the measurements from 404 to conditions for triggering a beam report. In some embodiments, the conditions may include signal quality of a neighbor beam exceeding a threshold value, a signal quality of a neighbor beam exceeding a signal quality of a beam currently serving the UE, a signal quality of a neighbor beam exceeding a signal quality of a beam currently serving the UE by greater than a threshold value, a signal quality of a beam currently serving the UE being below a threshold value, or some combination thereof. If the conditions for triggering the beam report are met, the procedure 400 may proceed to 408.
[0071] The procedure 400 may include beam report initiation in 408. For example, a beam report may be triggered based on the conditions being met in 406. The beam report initiation may include one or more of the features of the beam report procedures described throughout this disclosure for preparing for beam report transmission.

The base station 504 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 502 may have established a connection with the base station 504 to access a network.
[0074] A BR may be triggered in 506. For example, the UE 502 may identify a trigger for generation and / or transmission of a BR to the NW. The trigger may include the UE 502 determining that a channel quality of a neighbor beam exceeds a threshold value, a channel quality of a current serving beam is below a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, or some combination thereof.
[0075] The UE 502 may generate and / or transmit a first PUCCH message to the base station 504 in 508. The first PUCCH message may indicate that the UE 502 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message.
[0076] The base station 504 may identify the first PUCCH message received from the UE 502 in 508. The base station 504 may determine a resource to be utilized for a BR from the UE 502 based on the first PUCCH message. The base station 504 may generate and / or transmit a UL grant to the UE 502 in 510. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0077] The UE 502 may identify the UL grant received from the base station 504 in 510. The UE 502 may determine the resource to be utilized for the BR based on the UL grant. For example, the UE 502 may identify the indication of the resource to be utilized in the UL grant. The UE 502 may generate and / or transmit a BR transmission in PUSCH to the base station 504 in 512. The UE 502 may transmit the BR using the resource indicated in the UL grant.
[0078] FIG. 6 illustrates example BR transmission signaling arrangement 600 for a mode-B transmission scheme in accordance with some embodiments. For example, the arrangement 600 illustrates example operations and signals that may occur for mode-B UEI-BR transmission scheme.
[0079] The arrangement 600 includes a UE 602. The UE 602 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 600 further includes a base station 604, which may provide access to a network. The base station 604 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 602 may have established a connection with the base station 604 to access a network.
[0080] A BR may be triggered in 606. For example, the UE 602 may identify a trigger for generation and / or transmission of a BR to the NW. The trigger may include the UE 602 determining that a channel quality of a neighbor beam exceeds a threshold value, a channel quality of a current serving beam is below a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, or some combination thereof.
[0081] The UE 602 may generate and / or transmit a first PUCCH message to the base station 604 in 608. The first PUCCH message may indicate that the UE 602 has been triggered to transmit a beam report. The first PUCCH message may indicate a resource on which the BR will be transmitted. The UE 602 may have been previously configured with a resource and / or a type of resource for transmission of the BR. In some embodiments, an association may have been configured between the first PUCCH message and the resource for transmission of the BR. The association may be configured by RRC. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message.
[0082] The base station 604 may identify the first PUCCH message received from the UE 602 in 608. The base station 604 may identify the resource on which the BR is to be received from the first PUCCH message and may monitor for the BR on the resource.
[0083] The UE 602 may generate and / or transmit a BR transmission in PUSCH to the base station 604 in 612. The UE 602 may transmit the BR using the resource indicated in the first PUCCH message. The resource may be a type-1 CG PUSCH to carry the BR.
[0084] A DRX mechanism may be implemented by UEs. For CONNECTED UE power saving purpose, DRX mechanism may be configured by NW via dedicated RRC signaling in order to control the UE physical downlink control channel (PDCCH) monitoring activity in time domain.
[0085] When connected mode DRX (CDRX) is configured, the UE does not have to continuously monitor PDCCH. And the CDRX may be characterized by an on-duration, an inactivity-timer, a retransmission-timer, a DRX cycle, and / or an active-time. The on-duration may be a duration that the UE waits for, after waking up, to receive PDCCHs. If the UE successfully decodes a PDCCH, the UE stays awake and starts the inactivity timer. The inactivity-timer may be duration that the UE waits to successfully decode a PDCCH, from the last successful decoding of a PDCCH, failing which it can go back to sleep. The UE may restart the inactivity timer following a single successful decoding of a PDCCH for a first transmission only (i.e., not for retransmissions) . The retransmission-timer may be a duration until a retransmission can be expected. DRX cycle may specify the periodic repetition of the on-duration followed by a possible period of inactivity. The active-time may be a total duration that the UE monitors PDCCH. This includes the "on-duration" of the DRX cycle, the time UE is performing continuous reception while the inactivity timer has not expired, and the time when the UE is performing continuous reception while waiting for a retransmission opportunity.
[0086] The DRX active time (e.g., DRX active state) also may include the following period for uplink scheduling. If Scheduling Request is sent on PUCCH and is pending. During contention based random access (CBRA) , after the UE receives Msg2 but not receiving new dedicated UL grant.
[0087] If UE is not in DRX active time (e.g., the UE is in the DRX inactive state) , the UE will not report CSI on PUCCH and semi-persistent CSI on PUSCH. Further, the UE will not transmit periodic sounding reference signal (SRS) and semi-persistent SRS. The UE may still be allowed to transmit A-periodic CSI and SRS out of active time.
[0088] When DRX is configured, the Active Time for Serving Cells in a DRX group includes the time while: - drx-onDurationTimer or drx-InactivityTimer configured for the DRX group is running; or - drx-Retransmission TimerDL, drx-RetransmissionTimerUL or drx- RetransmissionTimerSL is running on any Serving Cell in the DRX group; or - ra-ContentionResolutionTimer (as described in clause 5.1.5) or msgB- ResponseWindow (as described in clause 5.1.4a) is running; or - a Scheduling Request is sent on PUCCH and is pending (as described in clause 5.4.4 or 5.22.1.5) . If this Serving Cell is part of a non-terrestrial network, the Active Time is started after the Scheduling Request transmission that is performed when the SR_COUNTER is 0 for all the SR configurations with pending SR (s) plus the UE-gNB RTT; or - a PDCCH indicating a new transmission addressed to the C-RNTI of the MAC entity has not been received after successful reception of a Random Access Response for the Random Access Preamble not selected by the MAC entity among the contention-based Random Access Preamble (as described in clauses 5.1.4 and 5.1.4a) ; or - there is an ongoing RACH-less LTM cell switch; or - there is an ongoing RACH-less handover in a terrestrial network.
[0089] FIG. 7 illustrates an example DRX arrangement 700 in accordance with some embodiments. For example, the DRX arrangement 700 illustrates example DRX cycles that may be implemented by a UE when configured in DRX operation.
[0090] The DRX arrangement 700 includes a plurality of subframes, such as subframe 702. A subframe may have a duration of 1 millisecond (ms) . In the illustrated DRX arrangement 700, the subframes illustrated with no fill (e.g., white subframes) indicate that the UE is not monitoring for incoming messages on one or more channels. The subframes illustrated with diagonal line fill indicate an on duration, such as on duration 704, where the UE is monitoring for incoming messages during a DRX cycle. The subframes illustrated with black fill indicate a continuous reception cycle, where the UE is monitoring for incoming messages.
[0091] The DRX arrangement 700 includes a long DRX cycle 706. The long DRX cycle 706 may have a duration defined by DRX cycle. For example, the long DRX cycle 706 may correspond to a number of subframes where the UE implements DRX cycle. The long DRX cycle 706 may be entered based on an expiration of an inactivity timer (which may be defined by inactivity-timer) and / or a completion of a short DRX cycle. The long DRX cycle 706 may include an on duration (such as the on duration 704) where the UE monitors for incoming messages and an off duration where the UE does not monitor for incoming message. The UE monitoring for incoming messages while in the on duration may be referred to as the UE being in an active state of a DRX cycle, and the UE not monitoring for incoming messages while in the off duration may be referred to as the UE being in an inactive state of a DRX cycle. A duration of the on duration may be defined by on-duration. The on duration may be defined to be at a beginning of a DRX cycle or at an end of a DRX cycle, where the remaining subframes of the DRX cycle are the off duration.
[0092] The DRX arrangement 700 includes a continuous reception period 708. The UE may continue to monitor for incoming messages during the continuous reception period 708. The UE may enter a continuous reception period, such as the continuous reception period 708, based on the UE receiving a message during a DRX cycle. In some embodiments, the message received during the DRX cycle may be a wake up message. The UE may schedule message reception at a beginning of the continuous reception period 708. The continuous reception period 708 may terminate at expiration of an inactivity timer (where the inactivity timer may be defined by inactivity-timer) or reception of a medium access control (MAC) control element (CE) that indicates the continuous reception period 708 is to be terminated and / or a DRX cycle is to be entered. In some embodiments, the MAC CE may indicate a type of DRX cycle that is to be entered.
[0093] The DRX arrangement 700 includes a short DRX cycle 710. In the illustrated embodiment, the short DRX cycle 710 is followed by a second short DRX cycle 712, where the second short DRX cycle 712 may include one or more of the features of the short DRX cycle 710. The short DRX cycle 710 may have a shorter duration than the long DRX cycle 706. In some instances, the short DRX cycle 710 may have duration that is half the length of the long DRX cycle 706. The short DRX cycle 710 may include an on duration where the UE monitors for incoming messages and an off duration where the UE does not monitor for incoming messages. The on duration may be defined by on-duration and may have a same length as the on duration 704 of the long DRX cycle. The off duration of the short DRX cycle 710 may be shorter than the off duration of the long DRX cycle 706.
[0094] Legacy situation of UEI-BR may present issues. When UEI-BR transmission is initiated in Mode-A, the UE will transmit the first PUCCH to request the UE dedicated UL grant to carry the BR in the allocated the second PUSCH resource. When UEI-BR transmission is initiated in Mode-B, the UE will transmit the first PUCCH, and transmit the BR via its associated Type-1 CG PUSCH resource. According to legacy DRX design, the UE will not monitor PDCCH / UE dedicated DCI if UE is not in DRX active time.
[0095] If UEI-BR is initiated not in DRX active time, and Mode-Ais configured for the BR transmission, UE may transmit the 1st UL PUCCH, but UE cannot acquire the UL grant for the BR transmission.
[0096] FIG. 8 illustrates example BR transmission signaling arrangement 800 for Mode-Awith DRX operation in accordance with some embodiments. For example, the arrangement 800 illustrates example operations and signals that may occur for mode-AUEI-BR transmission scheme with DRX enabled.
[0097] The arrangement 800 includes a UE 802. The UE 802 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 800 further includes a base station 804, which may provide access to a network. The base station 804 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 802 may have established a connection with the base station 804 to access a network.
[0098] The UE 802 may be in an off duration of a DRX cycle in the arrangement 800. For example, the UE 802 may be in an inactive state 806, where the UE 802 is not monitoring for incoming messages. The UE 802 may not be monitoring the PDCCH and / or the UE dedicated DCI.
[0099] A BR may be triggered for the UE 802 at 808. For example, the UE 802 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 802 may initiate a beam report procedure for mode-A based on the identifying the BR being triggered.
[0100] The UE 802 may generate and / or transmit a first PUCCH message to the base station 804 in 810. The first PUCCH message may indicate that the UE 802 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message.
[0101] The base station 804 may identify the first PUCCH message received from the UE 802 in 810. The base station 804 may determine a resource to be utilized for a BR from the UE 802 based on the first PUCCH message. The base station 804 may generate and / or transmit a UL grant to the UE 802 in 812. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0102] Due to the UE 802 being in the inactive state 806 of the DRX, the UE 802 may not be monitoring for incoming messages on one or more channels. Since the UL grant transmitted by the base station 804 in 812 arrives at the UE 802 while the UE 802 is still in the inactive state 806, the UE 802 may not identify the UL grant. Without identifying the UL grant, the UE 802 is not aware that the UE 802 has been granted a resource for transmission of the BR and is not aware of the resource to be utilized for the BR transmission. As such, the UE 802 may not transmit the BR transmission in 814. The lack of BR transmission reporting can cause service quality issues for the UE 802 and / or connection failure for the UE 802. Approaches described throughout this disclosure can ensure that the UE 802 identifies the UL grant, as well as avoiding the service quality issues and / or connection failure.
[0103] A first approach (which may be referred to as “Approach 1” ) may include where BR transmission triggers a UE entering DRX active time. For example, when BR transmission is initiated, the UE may enter DRX active time. The UE may be in the DRX active state during the DRX active time. The UE may identify a trigger for generation and / or transmission of a BR to a NW, and the UE may enter the DRX active state based on identifying the trigger. A new BR condition may be added to the active time for serving cells when DRX is configured, the new BR condition can be to trigger UE entering DRX active time based on the BR transmission being initiated and / or triggered.
[0104] A first option of the first approach (which may be referred to as “Approach 1a” ) may include, when BR is initiated, MAC enters DRX active time. For example, the UE may identify a trigger for a BR. A MAC layer of the UE may enter an DRX active state based on identifying the trigger for the BR. The first option of the first approach may be utilized for the mode-A UEI-BR transmission scheme or the mode-B UEI-BR transmission scheme.
[0105] FIG. 9 illustrates an example BR transmission signaling arrangement 900 for the first option of the first approach in accordance with some embodiments. For example, the arrangement 900 illustrates example operations and signals that may occur for the first option of the first approach.
[0106] The arrangement 900 includes a UE 902. The UE 902 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 900 further includes a base station 904, which may provide access to a network. The base station 904 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 902 may have established a connection with the base station 904 to access a network.
[0107] The UE 902 may be in an off duration of a DRX cycle in the arrangement 900. For example, the UE 902 may be in an inactive state 906, where the UE 902 is not monitoring for incoming messages. The UE 902 may not be monitoring the PDCCH and / or the UE dedicated DCI.
[0108] A BR may be triggered for the UE 902 at 908. For example, the UE 902 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 902 may initiate a beam report procedure for mode-A or mode-B based on the identifying the BR being triggered.
[0109] For the first option of the first approach, a MAC layer of the UE 902 may enter a DRX active time in response to the beam report procedure being initiated. In particular, the MAC layer may transition from the inactive state 906 to an active state 910 of the DRX during the DRX active time.
[0110] The UE 902 may generate and / or transmit a first PUCCH message to the base station 904 in 912. The first PUCCH message may be transmitted prior to or after the transition of the MAC layer to the active state 910. The first PUCCH message may indicate that the UE 902 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message. For mode-B, the first PUCCH message may indicate a resource on which the BR is to be transmitted.
[0111] The base station 904 may identify the first PUCCH message received from the UE 902 in 912. The base station 904 may determine a resource to be utilized for a BR from the UE 902 based on the first PUCCH message. The base station 904 may generate and / or transmit a UL grant to the UE 902 in 914. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0112] Due to the MAC layer of the UE 902 having transitioned to the active state 910, the MAC layer may be in the active state 910 when the UL grant arrives at the UE 902. The UE 902 may identify the UL grant due to the MAC layer being in the active state 910. The UE 902 may identify the UL grant received from the base station 904 in 914. The UE 902 may determine the resource to be utilized for the BR based on the UL grant. For example, the UE 902 may identify the indication of the resource to be utilized in the UL grant. The UE 902 may generate and / or transmit a BR transmission in PUSCH to the base station 904 in 916. The UE 902 may transmit the BR using the resource indicated in the UL grant.
[0113] A second option of the first approach (which may be referred to as “Approach 1b” ) may include, when first PUCCH transmission is performed, UE enters DRX active time. For example, the UE may transition to an active state based on the first PUCCH transmission of the BR transmission procedure being generated and / or transmitted.
[0114] A third option of the first approach (which may be referred to as “Approach 1c” ) may include, when first PUCCH transmission is performed, UE enters DRX active time after X milliseconds (ms) . For example, the UE may enter an active state at a defined time after the first PUCCH transmission of the BR transmission procedure is generated and / or transmitted. The defined time may be defined number of ms after the first PUCCH transmission.
[0115] FIG. 10 illustrates example BR transmission signaling arrangement 1000 for the second option of the first approach and / or the third option of the first approach in accordance with some embodiments. For example, the arrangement 1000 illustrates example operations and signals that may occur for the second option of the first approach and / or the third option of the first approach.
[0116] The arrangement 1000 includes a UE 1002. The UE 1002 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 1000 further includes a base station 1004, which may provide access to a network. The base station 1004 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 1002 may have established a connection with the base station 1004 to access a network.
[0117] A BR may be triggered for the UE 1002 at 1008. For example, the UE 1002 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 1002 may initiate a beam report procedure for mode-A or mode-B based on the identifying the BR being triggered.
[0118] The UE 1002 may generate and / or transmit a first PUCCH message to the base station 1004 in 1010. The first PUCCH message may indicate that the UE 1002 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message. For mode-B, the first PUCCH message may indicate a resource on which the BR is to be transmitted.
[0119] For the second option of the first approach, the UE 1002 may enter a DRX active time in response to the first PUCCH transmission in 1010. The UE may enter the DRX active time at transmission of the first PUCCH transmission or at a next opportunity after transmission of the first PUCCH transmission. For the second option of the first approach, the UE 1002 may enter a DRX active time at a defined time 1014 after the first PUCCH transmission in 1010. For the DRX active time, the UE 1002 may transition from the inactive state 1006 to the active state 1012 of the DRX. The UE 1002 transitioning to the active state 1012 may include a MAC layer of the UE 1002 transitioning to the active state.
[0120] The base station 1004 may identify the first PUCCH message received from the UE 1002 in 1010. The base station 1004 may determine a resource to be utilized for a BR from the UE 1002 based on the first PUCCH message. The base station 1004 may generate and / or transmit a UL grant to the UE 1002 in 1016. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0121] Due to the UE 1002 having transitioned to the active state 1012, the UE 1002 may be in the active state 1012 when the UL grant arrives at the UE 1002. The UE 1002 may identify the UL grant due to the UE 1002 being in the active state. The UE 1002 may identify the UL grant received from the base station 1004 in 1016. The UE 1002 may determine the resource to be utilized for the BR based on the UL grant. For example, the UE 1002 may identify the indication of the resource to be utilized in the UL grant. The UE 1002 may generate and / or transmit a BR transmission in PUSCH to the base station 1004 in 1018. The UE 1002 may transmit the BR using the resource indicated in the UL grant.
[0122] A second approach (which may be referred to as “Approach 2” ) may have BR transmission only initiated when a UE is in DRX active time, where the UE may be in an active state while in DRX active time. For the second approach, when BR is initiated not in DRX active time, the UE may delay the BR transmission until entering DRX active time.
[0123] A first option of the second approach (which may be referred to as “Approach 2a” ) may include the UE not delaying the 1st PUCCH transmission, but the UE starts to detect PDCCH to acquire the PUSCH resource for BR transmission when entering DRX active time. The first option of the first approach may be utilized for the mode-AUEI-BR transmission scheme or the mode-B UEI-BR transmission scheme.
[0124] FIG. 11 illustrates an example BR transmission signaling arrangement 1100 for the first option of the second approach in accordance with some embodiments. For example, the arrangement 1100 illustrates example operations and signals that may occur for the first option of the first approach.
[0125] The arrangement 1100 includes a UE 1102. The UE 1102 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 1100 further includes a base station 1104, which may provide access to a network. The base station 1104 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 1102 may have established a connection with the base station 1104 to access a network.
[0126] The UE 1102 may be in an off duration of a DRX cycle in the arrangement 1100. For example, the UE 1102 may be in an inactive state 1106, where the UE 1102 is not monitoring for incoming messages. The UE 1102 may not be monitoring the PDCCH and / or the UE dedicated DCI.
[0127] A BR may be triggered for the UE 1102 at 1108. For example, the UE 1102 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 1102 may initiate a beam report procedure for mode-A or mode-B based on the identifying the BR being triggered.
[0128] The UE 1102 may generate and / or transmit a first PUCCH message to the base station 1104 in 1110. The first PUCCH message may be transmitted prior to the transition of the UE 1102 to an active state 1112. For example, the UE 1102 may not delay the transmission of the first PUCCH message. The first PUCCH message may indicate that the UE 1102 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message. For mode-B, the first PUCCH message may indicate a resource on which the BR is to be transmitted.
[0129] After the UE 1102 transmits the first PUCCH message, the UE 1102 may remain in the inactive state 1106 as configured. For example, the triggering of the BR may not affect the configured transition from the inactive state 1106 to the active state 1112. The UE 1102 may transition from the inactive state 1106 to the active state 1112 at a time determined without consideration of the BR being triggered. Once in the active state 1112, the UE 1102 may monitor for incoming messages. For example, the UE may start monitoring for DCI messages when entering the DRX active time and may continue to monitor for DCI while the UE is in the active state 1112.
[0130] The base station 1104 may identify the first PUCCH message received from the UE 1102 in 1110. The base station 1104 may determine a resource to be utilized for a BR from the UE 1102 based on the first PUCCH message. In determining the resource to be utilized for the BR, the base station 1104 may identify when the UE 1102 is to transition to the active state 1112. The base station 1104 may wait until the UE 1102 has transitioned to the active state 1112 to transmit a UL grant in 1114. In some embodiments, the base station 1104 may determine when the UE 1102 is to transition to the active state 1112 and delay the UL grant transmission in 1114 until the UE 1102 has completed the transition. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0131] Due to the UE 1102 being in the active state, the UE 1102 may identify the UL grant received from the base station 1104 in 1114. The UE 1102 may identify the UL grant received from the base station 1104 in 1114. The UE 1102 may determine the resource to be utilized for the BR based on the UL grant. For example, the UE 1102 may identify the indication of the resource to be utilized in the UL grant. The UE 1102 may generate and / or transmit a BR transmission in PUSCH to the base station 1104 in 1116. The UE 1102 may transmit the BR using the resource indicated in the UL grant.
[0132] A second option of the second approach (which may be referred to as “Approach 2b” ) , may include the UE delaying the first PUCCH transmission until the UE enters the DRX active time. For example, when the BR transmission is triggered, the UE may continue with the configured transition from the DRX inactive state to the active state without consideration of the BR being triggered. However, rather than generating and / or transmitting signals related to the BR (in particular, the first PUCCH transmission) at the triggering of the BR, the UE may delay generation and / or transmission of the signal related to the BR until after the UE has transitioned to the active state. Accordingly, the UE may wait until the UE has transitioned to the active state to generate and / or transmit the first PUCCH transmission for the BR procedure.
[0133] FIG. 12 illustrates an example BR transmission signaling arrangement 1200 for the second option of the second approach in accordance with some embodiments. For example, the arrangement 1200 illustrates example operations and signals that may occur for the second option of the second approach.
[0134] The arrangement 1200 includes a UE 1202. The UE 1202 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 1200 further includes a base station 1204, which may provide access to a network. The base station 1204 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 1202 may have established a connection with the base station 1204 to access a network.
[0135] The UE 1202 may be in an off duration of a DRX cycle in the arrangement 1200. For example, the UE 1202 may be in an inactive state 1206, where the UE 1202 is not monitoring for incoming messages. The UE 1202 may not be monitoring the PDCCH and / or the UE dedicated DCI.
[0136] A BR may be triggered for the UE 1202 at 1208. For example, the UE 1202 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 1202 may initiate a beam report procedure for mode-A or mode-B based on the identifying the BR being triggered.
[0137] For the second option of the second approach, the UE 1202 may delay generation and / or transmission of a first PUCCH in the BR procedure until the UE 1202 is in an active state. The UE 1202 may transition from the inactive state 1206 to the active state based on a configuration for the transition without taking into account the BR being triggered. For example, the base station 1204 may provide RRC signaling indicating when the UE 1202 is to transition between the inactive state 1206 and the active state, where the base station 1204 may not take the BR being triggered into account when providing the RRC signaling.
[0138] The UE 1202 may transition from the inactive state 1206 to an active state 1210. For example, the UE 1202 may transition from a DRX inactive time to a DRX active time in accordance with RRC signaling from the base station 1204 and / or a configuration indicating when to transition to the active state 1210 without taking into account the BR being triggered.
[0139] For the second option of the second approach, the UE 1202 may generate and / or transmit a first PUCCH transmission to the base station 1204 in 1212 after the UE 1202 has transitioned to the active state 1210. For example, the UE 1202 may identify that the UE 1202 has transitioned from the inactive state 1206 to the active state 1210. Based on the identification of the transition, the UE 1202 may generate and / or transmit the first PUCCH transmission to the base station 1204. The first PUCCH message may indicate that the UE 902 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message. For mode-B, the first PUCCH message may indicate a resource on which the BR is to be transmitted.
[0140] The base station 1204 may identify the first PUCCH message received from the UE 1202 in 1212. The base station 1204 may determine a resource to be utilized for a BR from the UE 1202 based on the first PUCCH message. The base station 1204 may generate and / or transmit a UL grant to the UE 1202 in 1214. The UL grant may indicate the resource to be utilized for the BR. In some embodiments, the UL grant may be a DCI type of message.
[0141] Due to the UE 1202 having to the active state 1210, the UE 1202 may be in the active state 1210 when the UL grant arrives at the UE 1202. The UE 1202 may identify the UL grant due to the UE 1202 being in the active state 1210. The UE 1202 may identify the UL grant received from the base station 1204 in 1214. The UE 1202 may determine the resource to be utilized for the BR based on the UL grant. For example, the UE 1202 may identify the indication of the resource to be utilized in the UL grant. The UE 1202 may generate and / or transmit a BR transmission in PUSCH to the base station 1204 in 1216. The UE 1202 may transmit the BR using the resource indicated in the UL grant.
[0142] A third option of the second approach (which may be referred to as “Approach 2c” ) , may include the UE delaying the first PUCCH transmission until the associated PUSCH transmission is in DRX active time. For example, the UE may determine whether a resource for transmission of the BR will be available in a current or next DRX active time. The UE may delay the first PUCCH transmission for the BR procedure until the resource is determined to be available in the current or next DRX active time.
[0143] FIG. 13 illustrates an example BR transmission signaling arrangement 1300 for the third option of the second approach in accordance with some embodiments. For example, the arrangement 1300 illustrates example operations and signals that may occur for the third option of the second approach. The arrangement 1300 illustrates a mode-B UEI-BR transmission scheme (i.e., no UL grant transmission) representation, although it should be understood that the third option of the second approach may also be utilized for mode-AUEI-BR transmission scheme (i.e., with UL grant transmission) as well.
[0144] The arrangement 1300 includes a UE 1302. The UE 1302 may include one or more of the features of the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) . The arrangement 1300 further includes a base station 1304, which may provide access to a network. The base station 1304 may include one or more of the features of the base station 108 (FIG. 1) and / or the network device 300 (FIG. 3) . The UE 1302 may have established a connection with the base station 1304 to access a network.
[0145] The UE 1302 may be in an off duration of a DRX cycle in the arrangement 1300. For example, the UE 1302 may be in an inactive state 1306, where the UE 1302 is not monitoring for incoming messages. The UE 1302 may not be monitoring the PDCCH and / or the UE dedicated DCI.
[0146] A BR may be triggered for the UE 1302 at 1308. For example, the UE 1302 may identify that a BR has been triggered based on a condition, such as a channel quality of a neighbor beam exceeding a threshold value, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam, a channel quality of a neighbor beam exceeds a channel quality of a current serving beam by a threshold value, and / or a channel quality of a current serving beam is below a threshold value. The UE 1302 may initiate a beam report procedure for mode-A or mode-B based on the identifying the BR being triggered.
[0147] For the third option of the second approach, the UE 1302 may be aware of the resource to be utilized for transmission of the BR without receiving a UL grant (such as the UL grant included in arrangement 1100 (FIG. 11) and / or the UL grant included in arrangement 1200 (FIG. 12) ) . The UE 1302 may identify whether the resource is available for BR transmission in the current or next DRX active time of the UE 1302. For example, the UE 1302 may be configured to transition from the inactive state 1306 to the active state 1310 in the illustrated embodiment. The UE 1302 may determine whether the resource for transmission of the BR will be available in the active state 1310, where the resource being available is illustrated by the BR transmission in 1314 of the illustrated embodiment. The UE 1302 may delay generation and / or transmission of a first PUCCH transmission of the BR procedure until the UE 1302 determines that the resource is available in the active state 1310.
[0148] Once the UE 1302 has determined that the resource is available in the next or current active time, the UE 1302 may generate and / or transmit a first PUCCH transmission to the base station 1304. In the illustrated embodiment, the UE 1302 may determine that the resource is available in the active state 1310, and may generate and / or transmit a first PUCCH transmission to the base station 1304 in 1312 based on the resource being determined to be available in the active state 1310. In the illustrated instance, the first PUCCH transmission is illustrated as being transmitted after the UE 1302 has transitioned to the active state 1310. In other instances, the first PUCCH transmission may be transmitted prior to the UE 1302 transitioning to the active state 1310. The first PUCCH message may indicate that the UE 1302 has been triggered to transmit a beam report and / or request a resource on which to transmit the beam report. In some embodiments, the first PUCCH message may be an UL request. In some embodiments, the first PUCCH message may be a different type of message from a PUCCH-SR message. For mode-B, the first PUCCH message may indicate a resource on which the BR is to be transmitted.
[0149] The UE 1302 may generate and / or transmit a BR transmission in PUSCH to the base station 1304 in 1314. The resource for the BR transmission may be preconfigured.
[0150] FIG. 14 illustrates an example procedure 1400 for beam report transmission in accordance with some embodiments. The procedure 1400 may be performed by a UE, such as the UE 104 (FIG. 1) , the UE 106 (FIG. 1) , and / or the UE 200 (FIG. 2) .
