Description

Method, device and readable storage medium for transmitting configuration information

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method and apparatus for transmitting configuration information, and a readable storage medium.

Background

In a fifth Generation (5 th-Generation, 5G) wireless communication system, support for eXtended Reality (XR) service types is required. XR includes augmented Reality (AugmentedReality, AR), virtual Reality (VR), cloud gaming (Cloud gaming), and the like. XR services have the characteristic of a fixed frame rate, and their service data arrives at a User Equipment (UE) with a fixed period, but there is an additional delay Jitter (Jitter) based on the fixed period.

To reduce the power consumption of the UE during XR communication, the UE may be in different power saving states. In addition, features that skip physical downlink control channel listening (pdcchskiping) are also introduced in Release 17, R17 of the third generation partnership project (3rd Generation Partnership Project,3GPP). According to the PDCCHbearing ping, the base station can instruct the UE to skip the monitoring of the PDCCH in a set period, so that the energy saving is further realized.

XR service data may arrive at the UE after delay due to delay jitter, so the UE in the state of monitoring PDCCH may wait for a period of time, and the waiting time may always perform unnecessary blind detection of PDCCH, so there is still a problem of wasting energy consumption of the UE.

As shown in fig. 1, a method for transmitting configuration information provided in an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. Wherein the user equipment 101 is configured to support carrier aggregation and is connectable to a plurality of carrier units of the network device 102, including one primary carrier unit and one or more secondary carrier units.

It should be appreciated that the above wireless communication system 100 is applicable to both low frequency and high frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD) systems, worldwide interoperability for microwave access (worldwide interoperability for micro wave access, wiMAX) communication systems, cloud radio access network (cloud radio access network, CRAN) systems, future fifth Generation (5 th-Generation, 5G) systems, new Radio (NR) communication systems, or future evolved public land mobile network (public land mobile network, PLMN) systems, and the like.

The user equipment 101 shown above may be a terminal (terminal), an access terminal, a terminal unit, a terminal station, a Mobile Station (MS), a remote station, a remote terminal, a mobile terminal (mobile terminal), a wireless communication device, a terminal agent, a terminal device, or the like. The user device 101 may be provided with wireless transceiver functionality that is capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, including but not limited to the illustrated network device 103.

The user equipment 101 may be, among other things, a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN network, etc.

Network device 102 may be an access network device (or access network site). The access network device refers to a device that provides a network access function, such as a radio access network (radio access network, RAN) base station, etc. The network device 103 may specifically include a Base Station (BS), or include a base station and a radio resource management device for controlling the base station, or the like. The network device 102 may also include relay stations (relay devices), access points, base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations, etc. Network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

For example, network device 102 includes, but is not limited to: a next generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in LTE system, a radio network controller (radio network controller, RNC), a Node B (NB) in WCDMA system, a radio controller under CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in GSM system or CDMA system, a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmission point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a mobile switching center, or the like.

Fig. 2 is a schematic diagram of XR traffic transmission. As shown in fig. 2, during XR service data (XRBurst) transmission, a Frame rate of a transmission data Frame is F Frames Per Second (FPS). In each period (1/F) of transmitting a data frame, for example, from transmitting a data packet K corresponding to a video data frame K to transmitting a data packet (k+1) corresponding to a video data frame (k+1), the delay jitter (jitter) is within a set range. Wherein the delay jitter and the packet size of the traffic data follow probability distributions (probability distribution), respectively.

Due to the presence of delay jitter in XR traffic, traffic data may arrive at the user equipment 101 in advance or delayed.

In the pdcchskiping mode, the network device 102 may instruct the user device 101 to perform the pdcchskiping for a set period of time when transmitting the current data frame. After a set period, the user equipment 101 wakes up to continue listening to the PDCCH. However, since the service data may arrive at the ue 101 with delay due to delay jitter, or because the duration of the set period is limited, the ue 101 needs to wait for a period of time after waking up to receive the next data frame. Thus, the ue 101 is always performing unnecessary PDCCH blind detection during the waiting time, which results in waste of power consumption of the ue 101.

Referring to fig. 3, fig. 3 is a method for transmitting configuration information according to an exemplary embodiment, as shown in fig. 3, the method includes steps S301 to S303, specifically:

in step S301, the network device 102 sends configuration information to the user device 101, where the configuration information includes at least one set of low power wake-up signals LP WUS listening configuration, where the LP WUS listening configuration includes a start listening time offset and an LP WUS listening period.

In step S302, the ue 101 receives configuration information sent by the network device 102, where the configuration information includes at least one set of low power wake-up signal LP WUS listening configuration, where the LP WUS listening configuration includes a start listening time offset and an LP WUS listening period.

In step S303, the user equipment 101 listens for LP WUS according to at least one set of LP WUS listening configurations.

In some possible implementations, the low power wake-up signal (Low power wake up signal, LP WUS) is a wake-up signal (WUS) that the user equipment 101 may receive in a sleep state.

In some possible implementations, in the LP WUS transmission scenario, the user equipment 101 turns on a low power receiver through which WUS transmitted by the network device 102 is exclusively received. The low-power consumption receiver has small power, and can realize the energy-saving effect. The network device 102 needs to send the downlink data to be transmitted to the ue 101, but when the ue 101 is in the sleep state, the network device 102 needs to wake up the ue 101 using the LP WUS signal, and then schedule the downlink data transmission for the ue 101.

In an example, after the low power receiver receives the wake-up signal, the ue 101 may determine to turn on the host, transition from the sleep state to the active state for normal operation, and monitor the PDCCH.

In some possible implementations, the sleep state of the user equipment 101 includes: deep sleep (deep sleep), light sleep (light sleep), and micro sleep (micro sleep), the user equipment 101 can effectively save energy while in a sleep state. The micro sleep state enables the user equipment 101 to be in the shallowest sleep state, so that the user equipment can be quickly converted from the shallowest sleep state to the active state of normal operation, and the conversion time is very short and negligible.

In an example, the user equipment 101 is in a micro sleep state while listening to the LP WUS.

In some possible embodiments, after network device 102 sends each frame XR service data frame, user device 101 may be instructed to conduct a period of pdcchskiping. And after transmitting the frame data, transmits configuration information to the user equipment 101 so that the user equipment 101 listens to the LP WUS.

In an example, the network device 102 may indicate an X period of pdcchskipediping in the downlink control information (Downlink Control Information, DCI). During period X, the user equipment 101 may skip the listening of the PDCCH, in a sleep state.

In an example, the network device 102 configures the number of X periods through higher layer signaling. For example, 2X periods are configured.

In the disclosed embodiment, the network device 102 indicates the LP WUS listening configuration to the user device 101 through the sent configuration information. The user equipment 101 can monitor the LP WUS by adopting a low-power consumption receiver according to the initial monitoring time offset of the LP WUS and the LP WUS monitoring period, so as to monitor the PDCCH after monitoring the LP WUS, thereby reducing unnecessary PDCCH blind detection and saving the energy consumption of the user equipment.

Embodiments of the present disclosure provide a method of receiving configuration information, the method being performed by a user equipment 101. Referring to fig. 4, fig. 4 is a method for receiving configuration information according to an exemplary embodiment, and as shown in fig. 4, the method includes steps S401 to S402, specifically:

in step S401, the ue 101 receives configuration information sent by the network device 102, where the configuration information includes at least one set of low power consumption wake-up signal LP WUS listening configuration, where the LP WUS listening configuration includes a start listening time offset and an LP WUS listening period.

In step S402, the user equipment 101 listens for LP WUS according to at least one set of LP WUS listening configurations.

In some possible implementations, the user device 101 exclusively receives WUS transmitted by the network device 102 through a low power receiver. The low-power consumption receiver has small power, and can realize the energy-saving effect.

In some possible implementations, the user equipment 101 is in a micro sleep state when listening to the LP WUS. The micro sleep state is a state where the user equipment 101 is in the shallowest sleep state, and can be quickly converted from the shallowest sleep state to an active state of normal operation, and the conversion time is short. Therefore, even if the user equipment 101 is in the sleep state, the influence on the data transmission delay is small, and the data transmission delay performance can be ensured.

In some possible implementations, the network device 102 configures the user device 101 with a set of LP WUS listening configurations indicating a corresponding start listening time offset and LP WUS listening period.

In one example, as shown in FIG. 5, the XR service data has a frame rate of 60FPS, the period of transmitted data is 16.67ms, and the delay jitter is [4, -4] ms. The network device 102 configures a set of LP WUS snoop configurations with an LP WUS snoop period of 16ms and a start snoop time offset of 0ms. In this example, the user equipment 101 may listen to the LP WUS starting with slots 0ms, 16ms, 32ms … …, respectively.

In some possible implementations, the network device 102 configures multiple sets of LP WUS listening configurations for the user device 101, where the LP WUS listening periods indicated by each LP WUS listening configuration may be the same, with different starting listening time offsets.

In one example, the frame rate of XR traffic data is 60FPS, the period of transmitted data is 16.67ms, and the delay jitter is [4, -4] ms. The network device 102 configures a first LP WUS listening configuration and a second LP WUS listening configuration.

In this example, the LP WUS listening periods of the first LP WUS listening configuration and the second LP WUS listening configuration may both be 50ms, the initial listening time offset of the first LP WUS listening configuration is 0ms, and the initial listening time offset of the second LP WUS listening configuration is 16ms.

In the disclosed embodiment, the user equipment 101 learns the LP WUS listening configuration from configuration information received from the network equipment 102. The user equipment 101 can monitor the LP WUS by adopting a low-power consumption receiver according to the initial monitoring time offset of the LP WUS and the LP WUS monitoring period, so as to monitor the PDCCH after monitoring the LP WUS, thereby reducing unnecessary PDCCH blind detection and saving the energy consumption of the user equipment 101. In addition, since the user equipment 101 can be quickly converted from the micro sleep state to the active state of normal operation, the influence on the data transmission delay is small, and the data transmission delay performance can be ensured.

Embodiments of the present disclosure provide a method of receiving configuration information, the method being performed by a user equipment 101. The method comprises steps S401 to S402, wherein:

the configuration information comprises a plurality of sets of low-power consumption wake-up signals LP WUS monitoring configuration;

the LP WUS monitoring periods of the plurality of sets of LP WUS monitoring configuration instructions are the same, and the initial monitoring time offsets of the plurality of sets of LP WUS monitoring configuration instructions are different.

In some possible implementations, under a multi-set LP WUS listening configuration, user equipment 101 may employ a mechanism of multi-LP WUS listening configuration parallelism for LP WUS listening.

In some possible implementations, as shown in connection with fig. 5, a single LP WUS snoop configuration may face the phenomenon that the LP WUS snoop cycle does not match with a non-integer XR traffic data transmission cycle.

In the example of fig. 5, the frame rate of XR traffic data is 60FPS, the period of transmitted data is 16.67ms, and the delay jitter is [4, -4] ms. If the network device 102 configures a set of LP WUS snoop configurations, for example, the LP WUS snoop period of the LP WUS snoop configuration is 16ms, the initial snoop time offset is 0ms. As shown in connection with fig. 5, each transmit data cycle is offset from each LP WUS snoop cycle.

In some possible embodiments, the mismatch phenomenon described above is ameliorated by configuring multiple sets of LP WUS snoop configurations, with the starting snoop time of each LP WUS snoop configuration being offset in a different manner.

In one example, the frame rate of XR traffic data is 60FPS, the period of transmitted data is 16.67ms, the delay jitter is [4, -4] ms, and it is assumed that data is generated from the 4 th ms. The network device 102 configures a first LP WUS listening configuration, a second LP WUS listening configuration, and a third LP WUS listening configuration.

Wherein, the LP WUS listening periods of the first LP WUS listening configuration, the second LP WUS listening configuration and the LP WUS listening configuration may all be 50ms. The initial monitoring time offset of the first LP WUS monitoring configuration is 0ms, the initial monitoring time offset of the second LP WUS monitoring configuration is 16ms, and the initial monitoring time offset of the third LP WUS monitoring configuration is 33ms.

In this example, according to the first LP WUS listening configuration, the user equipment 101 will start listening of LP WUS at time slots 0ms, 50ms, 100ms … …, respectively.

According to the second LP WUS listening configuration, the user equipment 101 will start listening of the LP WUS at slots 16ms, 66ms, 116ms … …, respectively.

According to the third LP WUS listening configuration, the user equipment 101 will start listening of the LP WUS at slots 33ms, 83ms, 133ms … …, respectively.

In the embodiment of the disclosure, the network device 102 configures multiple sets of LP WUS listening configurations with different initial listening time offsets, and the user device 101 implements the listening of the LP WUS in parallel through the multiple sets of LP WUS listening configurations, so as to better match the transmission period of the XR service data.

Embodiments of the present disclosure provide a method of receiving configuration information, the method being performed by a user equipment 101. Referring to fig. 6, fig. 6 is a method of receiving configuration information according to an exemplary embodiment, and as shown in fig. 6, the method includes steps S601 to S603, specifically:

in step S601, the ue 101 receives configuration information sent by the network device 102, where the configuration information includes at least one set of low power wake-up signal LP WUS listening configuration, where the LP WUS listening configuration includes a start listening time offset and an LP WUS listening period.

In step S602, the user equipment 101 listens for LP WUS according to at least one set of LP WUS listening configurations.

In step S603, after the ue 101 monitors the LP WUS, it transitions from the sleep state to the working state and monitors the PDCCH.

In some possible embodiments, the user equipment 101 is in a micro sleep state when monitoring the LP WUS, and after monitoring the LP WUS, the ue transitions from the micro sleep state to an operating state to perform PDCCH monitoring. The length of this transition time is negligible.

In some possible implementations, the network device 102 configures a set of LP WUS listening configurations for the user device 101.

In one example, as shown in FIG. 5, the XR service data has a frame rate of 60FPS, the period of transmitted data is 16.67ms, and the delay jitter is [4, -4] ms. The LP WUS listening configuration configured by the network device 102 includes: the LP WUS listening period is 16ms and the initial listening time offset is 0ms. In this example, the user equipment 101 may listen to the LP WUS starting with slots 0ms, 16ms, 32ms … …, respectively.

In some possible implementations, the network device 102 configures multiple sets of LP WUS listening configurations for the user device 101.

In one example, the frame rate of XR traffic data is 60FPS, the period of transmitted data is 16.67ms, and the delay jitter is [4, -4] ms. The network device 102 configures a first LP WUS listening configuration, a second LP WUS listening configuration, and a third LP WUS listening configuration.

Wherein, the LP WUS listening periods of the first LP WUS listening configuration, the second LP WUS listening configuration and the LP WUS listening configuration may all be 50ms. The initial monitoring time offset of the first LP WUS monitoring configuration is 0ms, the initial monitoring time offset of the second LP WUS monitoring configuration is 16ms, and the initial monitoring time offset of the second LP WUS monitoring configuration is 33ms.

For ease of understanding, the listening flow in embodiments of the present disclosure may be referred to as the following example:

The information listening process in this example may include the following steps performed in a loop:

in step S11, the ue 101 is in the listening LP WUS state from a slot of 0ms, and receives the LP WUS signal at the slot2 end position.

In step S12, the user equipment 101 wakes up from slot3 and receives PDCCH/PDSCH of the first data frame. Wherein the network device 102 indicates PDCCH skip in the PDCCH of slot 5.

In step S13, the user equipment 101 ends the reception of the first data frame in slot 5.

In step S14, the user equipment 101 starts to enter the PDCCH skip state from slot6 according to the PDCCH of slot 5.

In step S15, the user equipment 101 transitions from slot16 to the micro sleep state again and listens to the LP WUS.

In the embodiment of the disclosure, the user equipment 101 performs LP WUS monitoring according to the LP WUS monitoring configuration configured by the network equipment 102, so that unnecessary PDCCH blind detection can be effectively reduced by monitoring the LP WUS, and the energy consumption of the user equipment 101 is saved; it is also ensured that the ue 101 may wake up immediately after the LP WUS is monitored, so that the influence of the energy-saving measures on the data transmission delay is reduced to the greatest extent, and the data transmission delay performance is ensured.

Embodiments of the present disclosure provide a method of receiving configuration information, the method being performed by a user equipment 101. Referring to fig. 7, fig. 7 is a method for receiving configuration information according to an exemplary embodiment, and as shown in fig. 7, the method includes steps S701 to S702, specifically:

In step S701, the user equipment 101 receives first information indicating that PDCCH monitoring is skipped.

In step S702, the ue 101 does not monitor PDCCH between the start time of performing skipped PDCCH monitoring and the start time of the next LP WUS monitoring period.

In some possible embodiments, the method further comprises steps S601 to S603, step S701 being performed during the performance of step S603 or after step S603.
