Abstract
Description
Technical Field
[0001] The present disclosure relates to wireless communications, and in particular, to Power Saving Signal (PSS) Monitoring Occasion (MO) configuration and capability signaling. Background Art
[0002] The 3rd Generation Partnership Project (3GPP) has developed and is developing standards for fourth generation (4G) (also known as Long Term Evolution LTE) and fifth generation (5G) (also known as New Radio NR) wireless communication systems. Such systems provide, among other features, broadband communications between network nodes such as base stations and mobile wireless devices (WDs), as well as communications between network nodes and between WDs. The non-limiting terms wireless device (WD) or user equipment (UE) are used interchangeably herein.
[0003] In the 3GPP RAN1 UE Energy Saving Study Project, Power Saving Signaling (PSS) based on Physical Downlink Control Channel (PDCCH) was agreed as a technique to improve UE power consumption. The agreed PDCCH-based Power Saving Signaling is associated with conventional Continuous Mode Discontinuous Reception (C-DRX). Power Saving Signaling (PSS) based on PDDCH is specifically considered as an effective implementation of this protocol.
[0004] The general idea of PSS is to send a power saving signal before the wake-up duration (ON-duration / ON duration) of C-DRX in case the network (NW) wants to wake up the UE within this ON-duration, and when PSS is detected, the UE must be woken up and monitor the PDCCH, for example, within the next ON-duration.
[0005] The New Radio (NR) standard in 3GPP is designed to provide services for multiple use cases, such as enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and machine-type communications (MTC). Each of these services has different technical requirements. For example, the general requirement for eMBB is high data rates with medium latency and medium coverage, while URLLC services require low latency and high reliability transmission, but can be medium data rates.
[0006] One of the solutions for low-latency data transmission is a shorter transmission time interval. In NR, in addition to transmission in a time slot, mini-slot transmission is allowed to reduce latency. A mini-slot can consist of any number of 1 to 14 orthogonal frequency division multiplexing (OFDM) symbols. It should be noted that the concept of time slots and mini-slots is not specific to a particular service, which means that mini-slots can be used for eMBB, URLLC, or other services.
[0007] UE power consumption is an important metric that needs to be enhanced. Typically, a lot of power can be spent monitoring the PDCCH in LTE based on a DRX setting from the LTE field log. If a similar DRX setting with traffic modeling is used, the situation in NR may be similar because the UE needs to perform blind detection in its configured control resource set (CORESET) to identify if there is a PDCCH sent to it and act accordingly. Techniques that can reduce unnecessary PDCCH monitoring or allow the UE to sleep or wake up only when needed are desirable.
[0008] However, there are currently many challenges associated with the details of the underlying monitoring occasion (MO) configuration, and in particular with respect to the offset and range of the wake-up signaling / power saving signaling configuration. Summary of the invention

The wireless device 121 can refer to any type of wireless device (WD) or user equipment (UE) that communicates with a network node and / or another wireless device in a cellular, mobile or radio communication network or system.
[0056] As part of the development of the embodiments described herein, it has been recognized that there are currently certain challenges related to UE power saving mechanisms in 3GPP, which will be described in detail below. More specifically, it is expected that the PDCCH-based power saving signal (PSS) outside of active time will be configured with an offset before the ON duration of the C-DRX cycle (referred to herein as the WUS offset or PSS offset) and with a configured range (referred to herein as the WUS range or PSS range).
[0057] The following description details the details of the lower layer monitoring opportunity (MO) configuration, particularly with respect to WUS / PSS offset and WUS / PSS range and the criteria for selecting the appropriate offset and range. As noted, the terms WUS and PSS, extended PSS configuration and PSS configuration, WUS offset and PSS offset (sometimes referred to as PS_offset), and WUS range and PSS range are used interchangeably herein.
[0058] refer to Figure 2 and Figure 3 , an example scenario is where the UE is configured with a specific DRX configuration, including at least an "ONduration" configuration 3, and a long and / or short DRX cycle 9 configuration. In addition, according to some embodiments, the UE may be configured with one or more PSS monitoring opportunities (MO) 2 that occur before ONduration 3. Thus, the PSS MO 2 may be in a PSS monitoring window (MW) 7 that starts at a point before ON duration 3 of the DRX cycle and ends at another point before ON-duration 3 of the DRX cycle 9.
[0059] PSS or WUS 8a can be based on a signal sent on the PDCCH using an existing or new downlink control information (DCI) format. If a DCI-based scheme is used, the coding chain specified in Rel-15 can be reused, including the CRC payload interleaver. In Rel-15, DCI with a smaller number of information bits is discussed and handled by the following principles, namely the principles obtained in 38.212, subclause 7.3.1. Therefore, the Rel-15 PDCCH channel coding and payload interleaver can already handle the case where the number of information bits in the DCI is less than 12 bits by appending zeros until the payload size is 12. Subsequently, the 24-bit CRC is appended with a 16-bit RNTI mask. The UE can improve detection performance by bringing additional information (such as 24 bits of CRC for zero padding bits and additional weight for error correction) into the Polar SSCL decoding.
[0060] The UE decodes the DCI and if the PSS 8a is intended to wake up the UE (either specifically or as part of a group), the UE monitors the PDCCH at a PDCCH monitoring opportunity (MO) 4 during the next ON duration 3, as shown in FIG. Figure 2 Indicated by the dashed box 1a in the DRX cycle. Note that these monitoring opportunities (MO) 4 associated with the ON duration of the DRX cycle are different from the WUS / PSS MO 2. Alternatively or additionally, when PSS 2 is detected, the UE follows the actions configured / commanded by the NW (e.g., generating non-periodic CSI reports, scheduling PDSCH through PSS, etc.). Alternatively or additionally, the UE can trigger the MAC entity to start the "DRX ONDuration timer".
[0061] Otherwise, if the UE does not detect PSS / WUS 8a (such as Figure 2 ), the UE may skip monitoring the PDCCH in the next opportunity 3, or follow other types of NW configuration / command operations when the PSS / WUS 8a is not detected. For example, in some embodiments, the UE may monitor the PDCCH in a search space (SS) different from the conventional search space (SS) and with a longer period.
[0062] According to some embodiments, when the UE is not in active time (e.g., before ON duration), a PSS is sent to indicate wake-up and monitor PDCCH in ON Duration. In this case, since the UE does not monitor any scheduling DCI at the same time, the BD / CCE / DCI budget for the power saving signal PSS does not need to be shared with the UE's scheduling DCI. Therefore, there is greater flexibility in configuring these parameters (BD / CCE / DCI) for PSS.
[0063] Therefore, the PSS based on the PDCCH should indicate "wake up" or not, based on which the UE can decide to decode / not decode the subsequent PDCCH monitoring opportunity. In addition, a bit field can be configured to indicate the transition from "dormancy-like" to "non-dormancy like" behavior on the activated Scell.
[0064] Furthermore, besides allowing link adaptation for PSS, reducing the number of information bits in the DCI is also beneficial as it can yield significant performance gains (from 16 bits -> 1 bit, ~1 dB). Therefore, the design of the PSS DCI should allow the use of a very small number of information bits in the DCI addressed to the UE. Thus, if the NW wants to do so, it should be able to not configure some bit fields, especially those related to L1-based mechanisms, to transition the UE from sleep-like behavior to non-sleep-like behavior.
[0065] Furthermore, with regard to the DCI size / format for PDCCH-based PSS, since it can be expected that PDCCH-based PSS will always be monitored separately from scheduled PDCCH monitoring, a new DCI format size can be configured independently. This allows for a more compact and robust DCI size to be used and will not be impacted by the DCI format size budget applicable during activity.
[0066] Furthermore, it is assumed that WUS / PSS is used to address a group of UEs, e.g. for wake-up. This can be done using methods such as TPC-PUXCH-RNTI, where PSS for multiple UEs is sent in one PDCCH and each UE is allocated a specific DCI bit for its corresponding wake-up indication.
[0067] Like some DCI formats 2-x, in some embodiments, the number of information bits in the new DCI format may be configurable from a higher layer, and for indicating wake-up or not, this will only require 0 or 1 bit of information. In addition, according to some embodiments, the NW may decide to configure or not configure an additional bit field with a specific bit width size to accommodate the L1-based mechanism to transition the UE from a sleep-like behavior to a non-sleep-like behavior. The size of this bit field corresponds to the number of Scell groups configured by the NW.
[0068] Furthermore, since the WUS / PSS DCI can address a single UE or a group of UEs in a transparent manner, higher layers can be used to indicate to the UE where the relevant information for that UE is via the starting position (S) and length (L) values within the new DCI.
[0069] An optional length (L) may also be indicated, which may support a length in the range of 1 to L bits, where L includes one bit for a wake-up or not indication, and the other L-1 bits are related to the Scell transition indication from sleep to non-sleep type behavior. According to some embodiments, in the case where the Scell adaptation indication is to be included in the PSS DCI, the length may also be obtained from the number of Scell groups configured for the PSS Scell transition indication, and thus the starting position configuration should be sufficient, and the UE may automatically infer the length of the associated bit field. L=0 indicates a fixed DCI payload (e.g., a DCI with information bits set to all zeros). L=1 allows a group DCI with a wake-up indication for each UE signal, i.e., an explicit indication of wake-up or not for each UE. Note that the NW may also assign the same bit field that is transparent to the UE to a UE or a group of UEs.
[0070] Since DCI may be addressed to a single UE or a group of UEs, the search space used for PSS transmission may be configurable for additional flexibility according to some embodiments.
[0071] More specifically, up to ten search spaces can be configured for the UE for PDCCH monitoring in the active time in the BWP. Additional search spaces can be configured for the UE, or one of the existing search spaces configured for PDCCH monitoring in the active time can be reused. It has been agreed that this should be at least CSS. Configuring PSS in UESS can also bring benefits. Although PS-RNTI is considered to be a universal RNTI for the group, it can also be associated with a single UE, and the PSS DCI field can also be configured only for one UE, so some people may argue that using CSS in this case is a waste of public resources and may increase the PDCCH blocking probability. If the number of UEs assigned to each group is small, or there are multiple groups with a single UE, the blocking probability can be particularly increased. Thus, since a dedicated SS will be designed for PSS, it can also be independent of the general SS design paradigm and allow the use of UESS for PSS monitoring, especially when PS-RNTI is associated only with a single UE. In this case, using UESS seems to be more attractive than CSS and reduces the PDCCH blocking probability.
[0072] Figure 3 An example of a PSS configuration with a PSS offset of 5 and a PSS range of 6 is shown. The PSS offset of 5 and the PSS range of 6 define the starting point 5 and length of the PSS monitoring window (MW) within which at least one PSS monitoring opportunity (MO) 2 occurs. PSS MO 2 is represented by a diagonal bar, while non-PSS MO is represented by a blank bar 7. Here, the PSS offset of 5 is five slots and the PSS range of 6 is four slots. Since the search space has a period of one slot, the four slots after the PSS offset of 5 are considered as PSS MO 2.
[0073] In the following, some mechanisms for configuring PSS MO 2 based on PDCCH are disclosed according to some embodiments. The same principle can be extended to other PDCCH-based energy saving signals outside the active time. In the following, some embodiments define how two parameters of PSS MO 2 can be configured, namely, PSS offset 5 and PSS range 6. The term "active time" is interpreted as during the ON duration of the DRX cycle. Therefore, outside the active time can be, for example, the time period before the ON duration of DRX.
[0074] In some embodiments, one or more PSS MOs 2 may be configured using an explicit offset or offset range. For example, a network node (e.g., gNB) may configure an explicit offset (in terms of slot duration (e.g., X slots before the ON duration of the DRX cycle) or duration (e.g., Y ms before the start of the ON duration of the DRX cycle) to the UE via higher layers (e.g., RRC signaling). Thus, the PSS offset 5 may be configured relative to the start time / starting point of the ON duration window 3 of the DRX. According to some embodiments, the PSS range 6 includes multiple search space sets that define the length of the PSS MW.
[0075] The explicit offset itself can be used as an indication of in which time slot the PSS MO 2 is expected. In addition, the exact PSS MO 2 can be configured via a lower layer PDCCH configuration including SS and CORESET associations. Thus, MO 2 can appear after the PSS offset value as configured via SS and Coreset associations. Therefore, the UE may not need to monitor the SS configured before the offset. According to some embodiments, the offset value may be part of the cell, BWP or SS configuration. For example, some SSs (i.e., one or more) may be dedicated to energy-saving signals outside of active time, whereby each dedicated SS is configured with an offset before the ON duration instead of the SS period.
[0076] In addition, according to some embodiments, the PSS configuration includes a first PSS offset and / or a first PSS range for a short DRX cycle and a second PSS offset and / or a second PSS range for a long DRX cycle. Here, the first PSS offset is different from the second PSS offset, and the first PSS range is different from the second PSS range. In other words, the network node (e.g., gNB) can configure different PSS offsets 5 or ranges of PSS offsets 5 for short and long DRX cycles 9. For example, for one or more wireless devices, the network node may determine to configure PSS MO 2 to be three time slots before the ON duration of long DRX and one time slot before the ON duration of short DRX. Alternatively, the network node may consider the time slot range for short DRX to be shorter than the time slot range for long DRX, or vice versa. Although the example is presented in terms of time slots, the same principle applies to PSS offset ranges defined by time ranges (e.g., 2-5ms or 4-6ms).
[0077] Simulation results show that WUS / PSS provides power savings for both long and short DRX, with a small drop in UPT. Therefore, independent configuration of WUS / PSS for long and short DRX may be more beneficial as it provides more flexibility in choosing the trade-off.
[0078] Furthermore, with respect to the range of values to be considered for the WUS / PSS offset, it has been shown that a larger PSS offset results in a decrease in user perceived throughput (UPT), and therefore the PSS offset should be as small as possible. This should be taken into account when considering the PSS offset range. Therefore, according to some embodiments, the WUS / PSS offset is in the range of 1 slot to 10ms (or an equivalent value at the slot level). This provides advantages in terms of limited UPT loss in the UE due to the WUS / PSS, and provides the NW with flexibility in sending the WUS / PSS.
[0079] According to some embodiments, the network node or "network" (NW) may configure an offset 5 that is long enough for PSS PDCCH processing in the current receiver mode of the WD, or for a possible BWP change in front of "onDuration monitoring" (i.e., monitoring MO 4 within ON Duration 3 of DRX cycle 9). However, the offset 5 does not have to be longer than required in these aspects to avoid remaining in a non-deep sleep state during an excessively long time interval between PSS 8a and ON duration 3 of DRX cycle 9. According to some embodiments, particular attention is paid to the case where the NW configures a single PSS offset via higher layers. The same principles can be applied to other situations, such as, for example, configuring multiple PSS offsets for different cell groups or configuring a series of PSS offsets.
[0080] In some embodiments, the PSS offset 5 may be configured only for monitoring the PSS / WUS 8a in the P(S) cell. Nevertheless, if a secondary cell (Scell) is configured for the UE, the NW or network node may determine / decide to allocate different PSS offsets 5 for different Scell groups or for each Scell. In addition, in some embodiments, the PSS / WUS offset 5 and / or the PSS / WUS duration 6 are configured only for the primary cell (Pcell) of the network node.
[0081] The NW may determine the minimum PSS offset (or PS_offset) 5 to be configured for the UE based on the trade-off between power efficiency and UE throughput, as well as potentially other factors. According to some embodiments, the NW may determine the minimum PSS offset based on its past observations of UE processing time or capability signaling. For example, the NW may have noticed that the UE can process the PDCCH within one time slot or within Tms, whereby the NW may regard this as the minimum offset it can configure. The NW may determine the minimum offset on a per-cell, per-bandwidth part (BWP), per-subcarrier spacing (SCS), or per-SS basis. For example, if a 15KHz SCS is used, the NW may consider a minimum offset of 1 time slot, but if a 60kHz or 120kHz SCS is used, a minimum offset of 2 to 4 time slots may be considered, etc. UE capability signaling may be understood as part of the initial access signaling from the UE / WD to make the network aware of its capabilities, which may also be referred to as a UE capability report. The UE may also update the capabilities signaled / reported.
[0082] In addition, the NW may consider potential additional commands associated with the wake-up signal (WUS) 8a or the power saving signal (PSS) 8a when determining the minimum offset. More specifically, if the PSS 8a includes a BWP switching command, the NW may consider a larger minimum offset based on the type of BWP switching. In addition, if the PSS 8a is intended to transform the Scell from a sleep-like behavior to a non-sleep-like behavior or vice versa, the NW may decide to use a larger PSS offset 5, thereby allowing the UE to prepare for such a transition. According to some embodiments in which the UE is triggered with a CSI report using the PSS 8a, the UE may need to prepare its receiver for such a report, so the NW may configure a larger minimum PSS offset.
[0083] In addition, if the WUS or PSS configuration is intended for a group of UEs, the NW may further determine the minimum offset based on different criteria. According to some embodiments, the NW may determine the minimum offset with the minimum observed processing time for the UE, or the maximum minimum offset associated with each UE individually. However, according to some embodiments, the NW may determine the opposite and select the minimum offset based on the smallest possible minimum offset, etc.
[0084] After determining the minimum offset (note that determining the "minimum offset" is optional, and the NW can directly decide the PSS offset 5 arbitrarily), the NW decides how to configure the actual PSS offset 5. The NW can decide to configure the PSS offset 5 per cell, per BWP, or per SS. For example, the NW can configure different PSS offsets for different BWPs with different subcarrier spacings (SCS). For example, if the SCS in one BWP is larger than that in another BWP, the NW can configure a larger PSS offset 5 in the previous BWP, and vice versa. Alternatively, according to some embodiments, the NW may decide to configure the same PSS offset 5 for all BWPs, or if configured with a PSS, a PSS offset applicable to all underlying BWPs may be configured per cell.
[0085] To select PSS offset 5 in each of the above examples, the NW may use the minimum offset that it has determined as PSS offset 5, or add a margin to accommodate a higher level of flexibility. According to some embodiments, the NW may decide the margin so that PSSMO 2 is close to the synchronization signal block (SSB) measurement outside the active time. According to some embodiments, the NW may decide the margin based on the range (time slot or time) plus the minimum offset. According to some embodiments, and in particular when PSS is configured for multiple UEs, the NW may decide to align PSS offset 5 between UEs, or different UEs are configured with different PSS offsets 5. If PSS offset 5 is to be aligned for all UEs or a subset of UEs, the NW may consider different criteria to determine PSS offset 5. According to some embodiments, the PSS offset is determined based on the UE that processes the slowest PSS or the UE with the largest individual offset. In another example, the NW may make a decision based on the opposite criterion, that is, the PSS offset is determined based on the UE that processes the fastest PSS or based on an average value, etc.
[0086] The NW may further consider the additional delay impact of the PSS offset 5. A long offset moves the effective scheduling decision point earlier and increases the delay of data arriving between PSS 8a and the start of onDuration 3 by the additional cDRX cycle length 9. Therefore, the NW may limit the length of the PSS offset 5 to a minimum predetermined value based on the delay requirements of the current traffic type of the UE, or limit it to a value that limits the ratio of the offset 5 to the cDRX cycle to no more than a predetermined value (e.g., 5-10%).
[0087] Another parameter in configuring PSS MO 2 is the PSS range 6 after PSS offset 5, which can be understood as a PSS MO "window" (or PSS window). In other words, the UE monitors the PSS 8a in the PSS MO 2 configured within this range 6. The PSS range 6 can be defined in different ways, for example, Y time slots after PSS offset 5, Zms after PSS offset 5, or by multiple search space sets that the UE should monitor PSS MO 2.
[0088] According to some embodiments, range 6 may be configured per cell, per BWP, or per SS using high layer signaling, which indicates a range 6 of possible PSS opportunities 8a after PSS offset 5. According to some embodiments, range 6 may be part of a PDCCH-based PSS configuration using a search space (SS) information element (IE). For example, a new parameter called "PSS duration" or the like may be added to the SS IE to determine the number of times the same SS is repeated in the next slot.
[0089] According to some embodiments, the range is not explicitly configured but implicitly configured through SS IE configuration. For example, all configured MOs outside the active time (starting from PSS offset 5 until ON duration 3) can be considered as PSS MO 2.
[0090] To determine PSS range 6, according to some embodiments, the NW may make a decision based on the PDCCH blocking probability. In other words, in some embodiments, PSS range 6 may be determined by the network node based on the PDCCH blocking probability. Thus, the NW considers a range including multiple PSS MO2s to ensure that the blocking probability remains below a certain threshold. According to some embodiments, and in particular when wake-up signaling is configured for multiple UEs, the NW may decide whether the range is the same or different for different UEs.
[0091] According to some embodiments, the UE is configured to send UE assistance information indicating its preferred PSS range. The preferred PSS range may be further defined per cell, per BWP, per SCS, per SS, etc. For example, the UE may report its preferred PSS range per SCS as follows:
[0092]
[0093]
[0094] In addition, if the UE already knows the configured PSS offset of 5, it can adjust its preferred PSS range. For example, if the configured PSS offset of 5 is large enough, the values listed in the previous example can be used. However, if the PSS offset is considered not large enough, the listed values can be reduced accordingly. The upper limit of the PSS offset can be 10ms, or the equivalent value at the timeslot level for each parameter set, i.e., 10 timeslots for 15kHz, 20 timeslots for 30kHz, 40 timeslots for 60kHz, and 80 timeslots for 120kHz. This is calculated based on 10*2^μ, where μ is the parameter set number, for example, 0 for 15kHz, 1 for 30kHz, and so on.
[0095] One potential issue is related to the case where the UE is configured with an additional Scell, which may have a different parameter set than the Pcell. Here, since the PSS / WUS is only sent on the Pcell, the UE processing time for the PDCCH-PSS may be related to the parameter set on the Pcell. If the Pcell parameter set is smaller than the Scell, a smaller offset value can be considered a "baseline PSS offset". Nevertheless, at the ms level, it still provides enough time for the UE to be woken up and monitor PDCCH on all cells. The same argument applies to the opposite case, i.e., when the SCS on the Pcell is larger than the Scell, with the difference that in this case a larger "baseline offset" can be considered, which is still large enough for all cells to be woken up and monitor PDCCH.
[0096] In turn, the NW may configure the PSS / WUS range 6 for the UE as suggested by the UE or not. Furthermore, if the PSS / WUS configuration is intended for multiple UEs, the NW may decide to configure the PSS range 6 for each UE individually, or to align for all UEs or one or more subsets thereof. In the latter case, the NW may further decide to determine the PSS range 6 based on the suggested narrowest, widest, average PSS range 6, etc.
[0097] Similarly, the NW or network node may further consider UE assistance information when configuring PSS / WUS configuration, and in particular when configuring PSS / WUS offset 5. UE assistance may be provided via one or more of MAC CE based, RRC based, or UE capability signaling.
[0098] From a network perspective, it may be useful if all UEs supporting wake-up signaling can do so with similar PSS processing times. Having this baseline capability may allow efficient NW configuration and use of wake-up signaling, including group-based wake-up indication in downlink control information (DCI). Therefore, for UEs supporting wake-up signaling, a baseline capability for minimum PSS processing may be defined (i.e., mandatory).
[0099] According to some embodiments, the baseline processing time requirement for a UE supporting PSS may be as follows, which depends on the SCS of the WUS / PSS based on the PDCCH. These example values may be applicable to a simple "wake up or not" function.
[0100]
[0101] In some embodiments, PSS / WUS 8a indicates one or more actions (hereinafter "high-level commands"). Therefore, if PSS / WUS 8a indicates one or more high-level commands, a separate corresponding baseline minimum processing time requirement may also be defined. For example, if BWP switching, or CSI reporting / trigger is included in PSS / WUS 8a, the corresponding action for a given cell may be applied to the cell at the same time. More specifically, if BWP switching is indicated by PSS / WUS 8a and PSS / WUS is used to indicate wake-up, since the BWP switching will continue, the wake-up action (e.g., PDCCH monitoring in the next ON Duration 3) will be applied after the BWP switching is completed. For other cells without BWP switching, a conventional wake-up timeline may be applied.
[0102] In addition, according to some embodiments, the UE assistance information is a high-level signaling indicating the minimum processing time for the UE to process the PSS / WUS 8a. For example, the UE may determine the minimum processing time based (only) on the time it takes to process the PDCCH and / or be ready to "wake up" and monitor the PSS 8a at PSS MO 2, and / or taking into account other criteria such as the best configuration to provide power saving. In addition, in this regard, the UE assistance information may be based on or depend on a specific SCS, BWP, cell, etc. Some processing time requirements for different SCSs are listed below according to some embodiments.
[0103]
[0104] Furthermore, the UE may consider whether additional secondary cells (Scells) are configured and / or whether additional commands are included in the PSS payload, such as, for example, Scell activation or deactivation of Scells with mixed parameter sets, and adjust the minimum processing time accordingly.
[0105] In addition, according to some embodiments, the UE may additionally indicate via a second (advanced / fast) PSS / WUS processing time indication that it also has "fast processing capability", in other words, the UE is able to process PSS / WUS "faster". This may be parameter set specific signaling, i.e., the UE may support the second (advanced / fast) processing time only for a subset of parameter sets. Some second (advanced / fast) processing times for different SCSs are listed below according to some embodiments.
[0106]
[0107] Therefore, when deciding the PSS offset and monitoring opportunity configuration, the NW or network node may consider the "minimum processing time" of the UE. Therefore, in some embodiments, the NW or network node may decide / determine that the minimum processing time is considered as the minimum offset, or simply decide that the minimum processing time should be considered as the PSS / WUS offset 5. The process of configuring the PSS offset according to any embodiment provided herein may be followed.
[0108] Regarding "UE assistance information", according to some embodiments, the UE can indicate its preferred PSS offset to the NW. In turn, the NW can decide whether to configure the PSS offset 5 as suggested by the UE. If a group of UEs is to be addressed by wake-up signaling, the NW can decide to determine to align the PSS offset 5 for all UEs, or set them individually, or align them for a subset of UEs. If the PSS offset 5 is to be aligned for all UEs or a subset thereof within the same PSS configuration, the NW can further apply different criteria when selecting the PSS offset 5. For example, the NW can decide to select the longest preferred PSS offset, or the shortest, or the average, or any other suitable criteria.
[0109] Figure 4 It is a schematic flow chart representation of a method 400 performed by a WD for communicating with a network node in a wireless communication network according to an embodiment of the present disclosure. The method 400 includes configuring 401 a discontinuous reception (DRX) configuration for the WD, wherein the DRX configuration has an ON-duration configuration and a long / short DRX cycle configuration. The DRX configuration defines the timing and length of the ON-duration for the WD based on a message from the network node. In this context, the DRX configuration can be obtained from the network node via RRC signaling. Therefore, the method 400 may further include the step of receiving one or more messages from the network node.
[0110] The method 400 further includes configuring 402 a power saving signal (PSS) configuration for the WD based on a message from a network node, wherein the PSS configuration includes a PSS offset and a PSS range, and wherein the PSS offset and the PSS range define the starting point and length of a PSS monitoring window (MW), and at least one PSS monitoring opportunity (MO) occurs within the PSS MW. As similar to the above, the WD can be configured 402 via RRC signaling from the network node. In addition, the method 400 includes monitoring 403 a signal or channel at one or more PSS MOs within the PSS MW. The PSS can be a PDCCH-based PSS, and the monitoring 403 step can include monitoring the PDCCH at one or more PSS MOs. In some embodiments, the PSS configuration includes an SS association and a control resource set CORESET association for one or more PSS monitoring opportunities.
[0111] When the WD / UE is configured 402 with a WUS / PSS MO based on a combination of SS, WUS / PSS offset and WUS / PSS range as described in some embodiments of the present invention, the UE is expected to monitor 403 the PSS in the configured 402 MO, and if the UE receives a PSS with a wake-up indication in each PSS MO, it can be configured to monitor the PDCCH in the next ONduration of the DRX cycle.
[0112] If the WUS / PSS indicates that the UE is awakened or not awakened in any PSS MO, the UE can skip the remaining MOs and follow the NW indication. In addition, if the PSS MO conflicts with another event, such as, for example, when the WUS / PSS MO falls within the active time, the UE can follow the specified or configured activity. For example, if the UE must be awakened, if one or more WUS / PSS MOs fall within the active time, the UE does not need to monitor the WUS / PSS MO, but can be awakened directly at the ON duration.
[0113] However, in some embodiments, if there is no available WUS / PSS MO before the ON duration of the DRX cycle, the UE must be awakened and monitor PDCCH on the DRX cycle, unless it is otherwise configured by the NW or network node, or allowed by the standardized specification, etc. In the illustrative example, the DRX cycle is 160ms, the SS cycle is equivalent to 320ms, and thus there is no valid WUS / PSS MO every other DRX cycle, and therefore, the UE must be awakened and monitor PDCCH in the DRX cycle.
[0114] According to some embodiments, the UE is configured to be awakened at the WUS / PSS offset and ready to monitor 403 WUS / PSS MO. According to some embodiments, and in particular when the first WUS / PSS MO falls after the WUS / PSS offset, the UE may be configured to delay being awakened until the first WUS / PSS MO. In addition, the UE may be configured to select a suitable energy saving mode between WUS / PSS MOs based on the time distance between the WUS / PSS MOs.
[0115] In some embodiments, the UE may be configured to implement a suitable energy saving mode after the end of the WUS / PSS range until the ON duration of the DRX cycle based on an indication from the WUS / PSS. If the available time is short (e.g., one or two time slots), the UE may be configured to adopt an energy saving mode that allows the UE to quickly return to normal PDCCH monitoring, such as by, for example, turning off the RF antenna, etc. However, if the time is longer (e.g., a few milliseconds), the UE may be configured to adopt a more stringent energy saving mode and turn off additional modules.
[0116] In addition, according to some embodiments, the UE may further consider WUS / PSS statistics and / or historical data, in particular regarding monitoring of WUS / PSS MO 403. For example, the UE may be configured to note that the NW sends WUS / PSS to the UE in a specific WUS / PSS MO, or after a specific WUS / PSS MO, or between one WUS / PSS MO and another WUS / PSS MO, all or most of the time.
[0117] Therefore, the UE may be configured to skip monitoring 403 WUS / PSS in other WUS / PSS MOs that were not included under the previous conditions. In other words, the UE may be configured to skip monitoring 403 WUS / PSS in WUS / PSS MOs that are determined to be unlikely to be used by the NW or network module to send WUS / PSS. Nevertheless, in this case, the UE may need to ensure that specific conditions such as minimum detection performance, etc. are met. The UE may tentatively monitor 403 WUS / PSS MOs that may be skipped according to the above logic infrequently to continuously determine that no WUS / PSS transmission occurs there.
[0118] The PSS range may include multiple search space sets that define the length of the PSS MW. In addition, in some embodiments, the PSS offset defines a time offset or time slot offset of the starting point of the PSS monitoring window (MW) relative to the ON-duration, and the PSS range defines the duration or time slot duration of the PSS MW in which at least one PSS monitoring opportunity (MO) occurs. The PSS offset (also referred to as the WSU offset) can be a single value (e.g., 5 time slots, 15ms) or a range of values (e.g., 5-10 time slots, 15-30ms). Similarly, the PSS range (also referred to as the WSU range or WSU MO range) can be a single value (e.g., 4 time slots, 8ms) or a range of values (3-7 time slots, 6-14ms).
[0119] Furthermore, according to some embodiments, the method further comprises, when the PSS is detected during at least one PSS MO within the PSS MW, performing 405 at least one first action indicated in the PSS.
[0120] The first action indicated in the PSS may include at least one of the following actions:
[0121] • Monitoring a Physical Downlink Control Channel (PDCCH) at one or more PDCCH Monitoring Occasions (MO) in a subsequent / following ON-duration of the DRX cycle.
[0122] • Perform bandwidth part (BWP) switching.
[0123] Reporting Channel State Information (CSI).
[0124] • Performing secondary cell (Scell) adaptation.
[0125] Trigger the MAC entity to start the DRX ON-duration timer.
[0126] With reference to the above discussion of the implementation of UE energy saving measures or energy saving modes, the UE may be configured to adjust its above energy saving measures, such as those listed above, based on the fact whether the WUS / PSS includes additional commands / actions. For example, if the WUS / PSS triggers BWP switching in addition to being used for wake-up, the UE may need to stay awake longer between the WUS / PSS and the ONduration of the DRX cycle to perform the BWP switching.
[0127] Furthermore, according to some embodiments, the method 400 further comprises sending 404 a signal to the network node. The signal may indicate at least one of the following:
[0128] • WUS / PSS processing time 411 of the wireless device / UE.
[0129] WD / UE assistance information 412.
[0130] • Preferred WUS / PSS offset 413 for WD / UE.
[0131] • Preferred WUS / PSS range 413 for WD / UE.
[0132] • WD / UE type, WD / UE capabilities, and / or WD / UE processing time 414.
[0133] Therefore, the WUS / PSS configuration (i.e., at least one of the PSS offset and the PSS range) can be based on one or more of the WD / UE parameters signaled above. These parameters can be signaled by the WD / UE to the network node in one or more radio resource control (RRC) messages. In some embodiments, at least one of the PSS offset and the PSS duration is defined based on the duration or slot duration between the PSS MW and the ON-duration, and the length of the ON-duration depends on one or more WD capabilities. More specifically, in some embodiments, the duration or slot duration between the PSS MW and the ON-duration can be of sufficient length to allow the WD to perform a BWP change, or of sufficient length to allow a wake-up signal (WUS) PDCCH processing in the current receiver mode of the WD. In other words, the WD capability can be the time or slot duration required to perform a BWP change, or the time or slot duration required to perform a PSSPDCCH processing in the current receiver mode of the WD. The UE processing time includes information about the UE's PDCCH processing time and / or the UE's WUS / PSS processing time.
[0134] Additionally, in some embodiments, the method 400 further includes: when a PSS / WUS is not detected during at least one PSS / WUS MO within a PSS / WUS MW, performing 406 at least one of the following second actions:
[0135] • According to the DRX configuration, the WD is set 406 to sleep mode.
[0136] • Monitoring 406 the PDCCH in a different search space (SS) than the monitoring after the PSS is detected.
[0137] • Monitoring 406 the PDCCH in a different SS and with a longer periodicity than monitoring after detecting the PSS.
[0138] According to some embodiments, the WUS / PSS configuration further includes at least one of a period and a timing of one or more PSS MOs within the PSS MW. In addition, the WUS / PSS offset may be specific to a specific UE / WD. Similarly, the WUS / PSS range may be specific to a specific UE / WD.

[0141] The wireless device 550 or the processing circuit 551 therein is configured to configure a discontinuous reception (DRX) configuration for the WD, or may include a configuration unit 552, which is configured to configure a discontinuous reception (DRX) configuration for the WD, and the DRX configuration has an ON-duration configuration and a long / short DRX cycle configuration. The DRX configuration defines the timing and length of the ON-duration for the WD based on a message from a network node. The wireless device 550 or the processing circuit 551 therein or the configuration unit 552 is further configured to configure the PSS configuration for the WD based on a message from a network node.

[0142] Continuing, we will now refer to Figure 6 An exemplary embodiment of a method 600 for processing communications of a wireless device in a wireless communication network performed by a network node is described with reference to the schematic flow chart shown in FIG. Figure 6 It can be obtained by Figure 1 Illustrative examples of actions or operations taken or performed by a network node 110 in a wireless communication network 100 are described and shown. The method 600 includes determining 601 a discontinuous reception (DRX) configuration having an ON-duration configuration and a long / short DRX cycle configuration. The DRX configuration defines the timing and length of the ON-duration for a WD.
[0143] The method 600 further includes determining 602 a WUS / PSS configuration, wherein the WUS / PSS configuration includes a WUS / PSS offset and a WUS / PSS range, wherein the WUS / PSS offset and the WUS / PSS range define a starting point and a length of a WUS / PSS monitoring window (MW), within which at least one PSS monitoring opportunity (MO) occurs. In addition, the method includes sending 603 the DRX configuration and the PSS configuration to the WD.
[0144] As will be readily appreciated by those skilled in the art, the features, embodiments and advantages discussed above from the perspective of the UE / WD are similarly applicable to the perspective of the network node. Therefore, for reasons of clarity and brevity and to avoid excessive repetition, they will not be described in detail. For example, the WUS / PSS range included by determining 602 the WUS / PSS configuration may include multiple search space sets defining the length of the WUS / PSS MW. In some embodiments, the PSS configuration determined 602 further includes at least one of the period and timing of one or more PSS MOs within the PSS MW.
[0145] In addition, the method 600 may further include sending 604 a power saving signal (PSS) or a wake-up signal (WUS) to the WD according to the PSS configuration. In other words, the PSS may be sent 600 so as to be received by the WD at one or more PSS MOs. The PSS may be a PDCCH-based PSS, and the PSS configuration may include an indication of an instruction to monitor the PDCCH at one or more PSS MOs.
[0146] According to some embodiments, the PSS sent 604 may further include an indication of at least one of the following:
[0147] • An instruction to monitor a Physical Downlink Control Channel (PDCCH) at one or more PDCCH Monitoring Occasions (MO) in a subsequent / following ON-duration of the DRX cycle.
[0148] Trigger the MAC entity to start the DRX ON-duration timer.
[0149] ·Instructions for executing bandwidth part (BWP) switching.
[0150] · Instructions to report channel state information (CSI).
[0151] ·Execute the instruction of secondary cell (Scell) adaptation.
[0152] Furthermore, the method 600 may further include receiving one or more signals (eg, RRC messages) from the WD. The signal may indicate at least one of the following:
[0153] • WUS / PSS processing time 611 of the wireless device / UE.

[0155] • Preferred WUS / PSS offset 613 for WD / UE.
[0156] • Preferred WUS / PSS range 613 for WD / UE.
[0157] • WD / UE type, WD / UE capabilities, and / or WD / UE processing time 614.
[0158] Thus, the WUS / PSS configuration (i.e., at least one of the PSS offset and the PSS range) may be based on one or more of the WD / UE parameters signaled above. These parameters may be signaled by the WD / UE to the network node in one or more radio resource control (RRC) messages. In addition, the WUS / PSS offset may be specific to a particular UE / WD. Similarly, the WUS / PSS range may be specific to a particular UE / WD.

[0165] The network node QQ160 and WD QQ110 include various components described in more detail below. These components work together to provide network node and / or wireless device functions, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may include any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and / or any other components or systems that may facilitate or participate in the communication of data and signals via a wired or wireless connection.
[0166] As used herein, a network node refers to a device that is capable of, configured to, set to, and / or operable to communicate directly or indirectly with a wireless device and / or with other network nodes or devices in a wireless network to enable and / or provide wireless access to a wireless device and / or perform other functions (e.g., management) in a wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, node Bs, evolved node Bs (eNBs), and NR NodeBs (gNBs)). They can be classified based on the amount of coverage provided by the base station (or in other words, their transmit power levels), and they can also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station can be a relay node or a relay donor node that controls a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as a centralized digital unit and / or a remote radio unit (RRU), sometimes also referred to as a remote radio head (RRH). Such a remote radio unit may or may not be integrated with an antenna as an antenna-integrated radio. Portions of distributed radio base stations may also be referred to as nodes in a distributed antenna system (DAS). Yet another example of a network node includes an MSR device such as a multi-standard radio (MSR) BS, a network controller such as a radio network controller (RNC) or a base station controller (BSC), a base transceiver station (BTS), a transmission point, a transmission node, a multi-cell / multicast coordination entity (MCE), a core network node (e.g., MSC, MME), an O&M node, an OSS node, a SON node, a positioning node (e.g., E-SMLC), and / or an MDT. As another example, a network node may be a virtual network node as described in more detail below. However, more generally, a network node may represent any suitable device (or group of devices) that is capable of, configured to, arranged to, and / or operable to enable and / or provide a wireless device with access to a wireless network or to provide some service to a wireless device that has accessed a wireless network.

Figure 8The network node QQ160 shown in the exemplary wireless network may represent a device including a combination of the hardware components shown, but other embodiments may include network nodes with different combinations of components. It should be understood that the network node includes any suitable combination of hardware and / or software required to perform the tasks, features, functions, and methods disclosed herein. In addition, although the components of the network node QQ160 are depicted as a single box within a larger box or nested within multiple boxes, in practice, the network node may include multiple different physical components that make up a single shown component (for example, the device readable medium QQ180 may include multiple separate hard drives and multiple RAM modules).
[0168] Similarly, network node QQ160 can be composed of multiple physically separated components (e.g., NodeB components and RNC components, or BTS components and BSC components, etc.), and each component can have its own corresponding components. In some scenarios where network node QQ160 includes multiple separate components (e.g., BTS and BSC components), one or more separate components can be shared between several network nodes. For example, a single RNC can control multiple NodeBs. In this scenario, each unique NodeB and RNC pair can be regarded as a separate network node in some instances. In some embodiments, network node QQ160 can be configured to support multiple radio access technologies (RATs). In this embodiment, some components can be copied (e.g., separate device-readable media QQ180 for different RATs) and some components can be reused (e.g., the same antenna QQ162 can be shared by RATs). Network node QQ160 can also include multiple groups of various components shown for different wireless technologies (such as GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technology) integrated into network node QQ160.

[0202] Fig.10 is a schematic block diagram showing a virtualization environment QQ300 in which functions implemented by some embodiments can be virtualized. In the current context, virtualization means creating a virtual version of an apparatus or device that may include a virtualized hardware platform, storage device, and networking resources. As used herein, virtualization can be applied to a node (e.g., a virtualized base station or a virtualized radio access node) or a device (e.g., a UE, a wireless device, or any other type of communication device) or a component thereof, and involves an implementation in which at least a portion of a function is implemented as one or more virtual components (e.g., via one or more applications, components, functions, virtual machines, or containers executed on one or more physical processing nodes in one or more networks).
[0203] In some embodiments, some or all of the functionality described herein may be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments QQ300 hosted by one or more hardware nodes QQ330. Further, in embodiments where the virtual nodes are not radio access nodes or do not require radio connectivity (e.g., core network nodes), the network nodes may be fully virtualized.
[0204] Functionality may be implemented by one or more applications QQ320 (alternatively referred to as software instances, virtual devices, network functions, virtual nodes, virtual network functions, etc.) operable to implement some functionality, features, and / or benefits of some embodiments disclosed herein. Applications QQ320 run in a virtualization environment QQ300 that provides hardware QQ330 including processing circuitry QQ360 and memory QQ390. Memory QQ390 contains instructions QQ395 executable by processing circuitry QQ360, whereby applications QQ320 are operable to provide one or more features, benefits, and / or functionality disclosed herein.
[0205] The virtualized environment QQ300 includes a general-purpose or special-purpose network hardware device QQ330, which includes a set of one or more processors or processing circuits QQ360, which can be commercial off-the-shelf (COTS) processors, application-specific integrated circuits (ASICs), or any other type of processing circuits, including digital or analog hardware components or special-purpose processors. Each hardware device may include a memory QQ390-1, which may be a non-permanent memory for temporarily storing instructions QQ395 or software executed by the processing circuit QQ360. Each hardware device may include one or more network interface controllers (NICs) QQ370, also known as network interface cards, which include a physical network interface QQ380. Each hardware device may also include a non-temporary, permanent, machine-readable storage medium QQ390-2 in which software QQ395 and / or instructions executable by the processing circuit QQ360 are stored. Software QQ395 may include any type of software, including software for instantiating one or more virtualization layers QQ350 (also referred to as a hypervisor), software for executing virtual machines QQ340, and software that enables it to perform functions, features and / or benefits related to some of the embodiments described herein.

Different embodiments of instances of virtual device QQ320 can be implemented on one or more virtual machines QQ340, and can be implemented in different ways.
[0207] During operation, processing circuit QQ360 executes software QQ395 to instantiate a hypervisor or virtualization layer QQ350, which may sometimes be referred to as a virtual machine monitor (VMM). Virtualization layer QQ350 may present a virtual operating platform that appears to networked hardware to virtual machine QQ340.
[0208] like Fig.10As shown in , hardware QQ330 can be an independent network node with common or specific components. Hardware QQ330 can include antenna QQ3225, and some functions can be implemented via virtualization. Alternatively, hardware QQ330 can be part of a larger hardware cluster (e.g., such as in a data center or customer premise equipment (CPE)), where multiple hardware nodes work together and are managed via management and orchestration (MANO) QQ3100 (which oversees the life cycle management of application QQ320 together with other programs).
[0209] In some contexts, virtualization of hardware is referred to as network function virtualization (NFV). NFV can be used to consolidate multiple network device types onto industry-standard high-volume server hardware, physical switches, and physical storage devices that can be located in data centers and client devices.
[0210] In the context of NFV, a virtual machine QQ340 may be a software implementation of a physical machine that runs programs as if they were executed on a physical, non-virtual machine. Each virtual machine QQ340 and the portion of the hardware QQ330 that executes the virtual machine, i.e., the hardware dedicated to the virtual machine and / or the hardware shared by the virtual machine and other virtual machines QQ340, form a separate virtual network element (VNE).
[0211] Still in the context of NFV, a virtual network function (VNF) is responsible for handling specific network functions running in one or more virtual machines QQ340 on top of the hardware networking infrastructure QQ330 and corresponds to Fig.10 In some embodiments, one or more radio units QQ3200, each including one or more transmitters QQ3220 and one or more receivers QQ3210, may be coupled to one or more antennas QQ3225. The radio unit QQ3200 may communicate directly with the hardware node QQ330 via one or more suitable networks, and may be used in conjunction with a virtual component to provide radio functionality to a virtual node such as a radio access node or a base station. In some embodiments, some signaling may be implemented using a control system QQ3230, which may alternatively be used for communication between the hardware node QQ330 and the radio unit QQ3200.
[0212] refer to Fig.11According to an embodiment, a communication system includes a telecommunication network QQ410 such as a cellular network of the 3GPP type, which includes an access network QQ411 such as a radio access network and a core network QQ414. The access network QQ411 includes a plurality of base stations QQ412a, QQ412b, QQ412c, such as NB, eNB, gNB or other types of wireless access points, each base station defining a corresponding coverage area QQ413a, QQ413b, QQ413c. Each base station QQ412a, QQ412b, QQ412c can be connected to the core network QQ414 via a wired or wireless connection QQ415. A first UE QQ491 located in the coverage area QQ413c is configured to be wirelessly connected to the corresponding base station QQ412c or to be paged by the corresponding base station QQ412c. A second UE QQ492 located in the coverage area QQ413a can be wirelessly connected to the corresponding base station QQ412a. Although multiple UEs QQ491 , QQ492 are shown in this example, the disclosed embodiments are equally applicable to situations where only a UE is in the coverage area or a only UE is connected to the corresponding base station QQ412 .
[0213] The telecommunications network QQ410 itself is connected to a host computer QQ430, which may be embodied in the hardware and / or software of a standalone server, a cloud-implemented server, a distributed server, or as a processing resource in a server farm. The host computer QQ430 may be under the ownership or control of a service provider, or may be operated by or on behalf of a service provider. The connections QQ421 and QQ422 between the telecommunications network QQ410 and the host computer QQ430 may extend directly from the core network QQ414 to the host computer QQ430, or may be connected via an optional intermediate network QQ420. The intermediate network QQ420 may be one or a combination of more than one of a public, private, or managed network; the intermediate network QQ420 (if any) may be a backbone network or the Internet; in particular, the intermediate network QQ420 may include two or more sub-networks (not shown).
[0214] Fig.11The communication system as a whole implements a connection between the connected UE QQ491, QQ492 and the host computer QQ430. The connection can be described as an over-the-top (OTT) connection QQ450. The host computer QQ430 and the connected UE QQ491, QQ492 are configured to use the access network QQ411, the core network QQ414, any intermediate network QQ420 and possible other infrastructure (not shown) as intermediaries to transmit data and / or signaling via the OTT connection QQ450. The OTT connection QQ450 can be transparent in the sense that the participating communication devices through which the OTT connection QQ450 passes do not know the routes of the uplink and downlink communications. For example, the base station QQ412 may not or need not be informed of the past routes of the incoming downlink communications, wherein the incoming downlink communications have data that originates from the host computer QQ430 and will be forwarded (e.g., handed over) to the connected UE QQ491. Similarly, base station QQ412 need not be aware of the future routing of outgoing uplink communications originating from UE QQ491 to host computer QQ430.

In providing services to the remote user, the host application QQ512 may provide user data, which is sent using the OTT connection QQ550.
[0216] The communication system QQ500 also includes a base station QQ520, which is provided in the telecommunication system and includes hardware QQ525 enabling it to communicate with the host computer QQ510 and the UE QQ530. The hardware QQ525 may include a communication interface QQ526 for establishing and maintaining a wired or wireless connection with different communication devices in the communication system QQ500, and hardware QQ527 for establishing and maintaining a connection with at least those located in the coverage area served by the base station QQ520 (not in the coverage area). Fig.12 The communication interface QQ526 may be configured to facilitate a connection QQ560 to the host computer QQ510. The connection QQ560 may be direct, or it may pass through a core network (not shown in FIG. 1 ) in the telecommunications system. Fig.12 ) and / or through one or more intermediate networks external to the telecommunications system. In the illustrated embodiment, the hardware QQ525 of the base station QQ520 also includes processing circuitry QQ528, which may include one or more programmable processors, application specific integrated circuits, field programmable gate arrays, or a combination of these components (not shown) suitable for executing instructions.

The UE QQ530 also includes software QQ531, which is stored in or accessible to the UE QQ530 and can be executed by the processing circuit QQ538. The software QQ531 includes a client application QQ532. The client application QQ532 can be operated with the support of the host computer QQ510 to provide services to human or non-human users via the UE QQ530. In the host computer QQ510, the executing host application QQ512 can communicate with the executing client application QQ532 via the OTT connection QQ550 terminated at the UE QQ530 and the host computer QQ510. When providing services to users, the client application QQ532 can receive request data from the host application QQ512, and provide user data in response to the request data. The OTT connection QQ550 can transmit both the request data and the user data. The client application QQ532 can interact with the user to generate the user data it provides.

The network infrastructure can determine the routing, which can be configured to be hidden from the UE QQ530 or the service provider operating the host computer QQ510, or both. When the OTT connection QQ550 is active, the network infrastructure can further make decisions by which it dynamically changes the routing (e.g., based on load balancing considerations or reconfiguration of the network).
