Detailed Description
The present application will be described with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
The UE monitors the PDCCH at a certain period in a normal state, and stops monitoring the PDCCH in a sleep state, but continues to perform other activities, such as CSI measurement, AGC, BM, and the like. A certain switching time delay is arranged between the dormant state and the normal state, and the switching time delay is mainly determined by Tactivation_timeThe method comprises a Medium Access Control-Control Element (MAC-CE) analysis time delay, a Radio Frequency (RF) awakening time delay, an AGC adjustment time delay, a time-Frequency offset synchronization time delay and the like. When the UE is in the dormant state, the RF in the Secondary Cell (Scell) is not turned off, which may reduce the handover delay.
In the related art, the monitoring period of the PDCCH by the UE can be dynamically modified through a Downlink Control Information (DCI) signaling, the monitoring period in a normal state is relatively short and monitoring is frequent, while the monitoring period in a sleep state is relatively long and monitoring is sparse, but the dynamic indication method needs to occupy a large signaling overhead, and is low in efficiency; the UE may also be switched from the BWP in the dormant state to the BWP in the normal state (active) based on the BWP switching technology, which requires the UE to have the capability of configuring multiple BWPs, but this capability of configuring multiple BWPs is granular in frequency band (band), i.e. it does not support configuring multiple BWPs in some frequency bands, and in this case, the method for implementing UE state switching by using the BWP switching technology is no longer applicable. The related art method has limitations on signaling overhead or bandwidth limitation, and cannot efficiently indicate the handover of the UE between the sleep state and the normal state.
The present embodiment provides a handover indication method, which configures parameters through RRC signaling, determines target parameters according to the configured parameters, and sends the target parameters to a terminal through a control message, so as to indicate the terminal to perform state handover, where the control message is used to indicate the target parameters to the terminal, and the signaling overhead is small, and the method is applicable even when a UE does not have the capability of configuring multiple BWPs, so as to improve the applicability of state handover, and improve the handover efficiency by efficiently indicating state handover to the terminal.
Fig. 1 is a flowchart of a handover indication method according to an embodiment. The handover indication method of the present embodiment is applied to a service node. As shown in fig. 1, the method includes step 110 and step 120.
In step 110, the target parameters are determined according to the configuration parameters of the radio resource control RRC.
In this embodiment, the configuration parameters for instructing the UE to perform state switching may be configured through RRC signaling, where the state switching includes switching from a dormant state to a normal state and switching from the normal state to the dormant state. For example, the configuration parameter may be used to configure a monitoring period of the PDCCH by the UE on the Scell, for example, 2 PDCCH monitoring periods, one long period and one short period are configured on the Scell, the long period corresponds to the dormant state, and the short period corresponds to the normal state, and the UE may be further instructed to switch the PDCCH monitoring period through the control message, for example, 1 bit is used for switching the PDCCH monitoring period on one Scell, if the bit is configured to be 0, the UE is switched to the dormant state, otherwise, the UE is switched to the normal state; the configuration parameters may also be used to configure the BWP for handover, for example, configure the BWP in the dormant state and the BWP in the normal state, and the control message may further instruct the UE to switch from the BWP in the dormant state to the active BWP, thereby implementing the handover from the dormant state to the normal state, or the control message may further instruct the UE to switch from the active BWP to the BWP in the dormant state, thereby implementing the handover from the normal state to the dormant state. The configuration parameters can be one set or a plurality of sets, and the serving node can determine the target parameters from the configuration parameters according to actual requirements and indicate the target parameters to the UE.
In step 120, a control message is sent to the terminal, where the control message includes the target parameter, and the control message is used to instruct the terminal to switch between the sleep state and the normal state according to the target parameter.
In this embodiment, the control message may be DCI, and the BWP used by the Scell may be indicated by an indication field set in the DCI, or indicate whether to monitor the PDCCH in each secondary cell or indicate to switch monitoring periods and offsets of monitoring the PDCCH. The method of the embodiment does not require that the UE must have the capability of configuring multiple BWPs, and the control message is only used for indicating the target parameters, so that the signaling overhead is small.
In one embodiment, the configuration parameters include a first set of parameters and a second set of parameters; the first set of parameters includes a monitoring period and an offset of the PDCCH; the second set of parameters includes at least two BWPs, wherein at least one BWP corresponds to a dormant state.
In an embodiment, two sets of configuration parameters may be configured by the RRC, where the first set of configuration parameters is used to indicate a monitoring period and an offset of the PDCCH by the UE, where the offset is used to indicate a slot position for monitoring in one monitoring period, for example, if one monitoring period includes 10 slots, and the offset is 3, the PDCCH is monitored in a 3 rd slot of the 10 slots of the monitoring period. The second set of configuration parameters includes at least two BWPs, wherein at least one BWP is in a dormant state, and the UE is indicated with the second set of configuration parameters as target parameters, according to which the UE can implement state handover through BWP handover.
In an embodiment, the determining the target parameter according to the configuration parameter of the radio resource control RRC includes: selecting a target parameter in the first and second sets of parameters based on at least one of: the information of the frequency band, the information of the terminal capability, the information of the new air interface NR version supported by the service node or the terminal, and the information of the Scell activation delay requirement.
In the process of indicating the state handover to the terminal, the serving node may select one set of configuration parameters from the two sets of configuration parameters as target parameters, for example, in a case that the UE has the capability of configuring multiple BWPs in the current frequency band and supports BWP handover, the serving node may select a second set of configuration parameters as target parameters, and otherwise, may select a first set of configuration parameters as target parameters. For another example, when the UE has a service with a low delay requirement, the delay requirement for Scell activation is relatively high, and the serving node may select the first set of configuration parameters as the target parameters.
In an embodiment, the control message is sent through a Primary Cell (Pcell) or a scheduling Cell.
In an embodiment, the control message comprises a target parameter indication field; the bit quantity of the target parameter indication domain is m-1, and m-1 bits respectively correspond to m-1 auxiliary cells; or the number of bits of the target parameter indication domain is 2 times of m-1, and each 2 bits correspond to one secondary cell; where m denotes the maximum number of carriers supported by the NR system.
In this embodiment, the control message indicates the target parameter to the terminal through the target parameter indication field with a certain number of bits. For example, in a case where the serving node selects the first set of configuration parameters as the target parameters, for example, the gNB configures different PDCCH monitoring periods and offsets for the Scell, the target parameter indication field is used to indicate switching of different PDCCH monitoring periods and offsets; in the case that the serving node selects the second set of configuration parameters as the target parameters, for example, the gNB configures multiple BWPs for the Scell, the target parameter indication field is used to indicate handover of different BWPs.
In an embodiment, the target parameters of m-1 secondary cells may be indicated by m-1 bits, respectively, each bit corresponding to one secondary cell; alternatively, the target parameters of m-1 secondary cells are indicated by 2 x (m-1) bits, each 2 bits corresponding to one secondary cell, where m represents the maximum number of carriers supported by the NR system.
In an embodiment, the control message includes DCI, and a new DCI format defined in a Power Saving application scenario may be used.
In an embodiment, the configuration parameters comprise configuration parameters of a virtual BWP; the virtual BWP corresponds to a normal state BWP, and the virtual BWP is different from the corresponding normal state BWP in first configuration parameters; the second configuration parameters between the virtual BWP and the corresponding normal state BWP are the same.
In this embodiment, the serving node configures configuration parameters of a virtual BWP through RRC and sends the configuration parameters to the UE, where the virtual BWP is bound with a normal BWP, and configuring two BWPs for binding is equivalent to configuring only one BWP, but only part of configuration parameters (second configuration parameters) of the two BWPs are the same, and part of configuration parameters (first configuration parameters) are different, thereby improving the switching efficiency between the two BWPs. The switching of the configuration parameters of the virtual BWP and the corresponding configuration parameters of the BWP in the normal state is indicated to the UE through the control message, so that the UE can switch from the dormant state to the normal state by switching from the virtual BWP to the BWP in the normal state, or the UE can switch from the normal state to the dormant state by switching from the BWP in the normal state to the virtual BWP.
In an embodiment, the first configuration parameter includes at least one of: a search space of a PDCCH, a Control Resource Set (CORESET) configuration parameter, a Channel state information-Reference Signal (CSI-RS) configuration parameter, an aperiodic tracking Reference Signal (a-TRS) configuration parameter, a Sounding Reference Signal (SRS) configuration parameter, and a BM configuration parameter.
In an embodiment, the second configuration parameter comprises at least one of: bandwidth, Subcarrier Spacing (SCS), and center frequency points.
In one embodiment, the BWP is the same as the BWP Index (ID) of the corresponding normal-state BWP.
In an embodiment, the first configuration parameter is a BWP specific (Dedicated) parameter, and the second configuration parameter is a BWP Common (Common) parameter. In this embodiment, the configuration of the proprietary parameters and their sub-parameters between the first BWP and the second BWP may be different, and the common parameters are the same. For example, the BWP specific parameters include at least one of: physical Downlink Shared Channel configuration parameter (PDSCH-configuration), Physical Downlink control Channel configuration parameter (PDCCH-configuration), Semi-Persistent transmission configuration parameter (Semi-Persistent Scheduling-configuration, SPS-configuration), Radio Link Monitoring configuration parameter (Radio Link Monitoring-configuration), Physical uplink data Channel configuration parameter (PUSCH-configuration), Physical uplink control Channel configuration parameter (PUCCH-configuration), configuration authorization configuration parameter (Configured Grant-configuration), sounding reference signal configuration parameter (SRS-configuration), Beam Failure Recovery configuration parameter (Beam Failure Recovery-configuration); the BWP common parameters include at least one of: a physical downlink control channel common configuration parameter (PDCCH-config common), a physical downlink data channel common configuration parameter (PDSCH-config common), a general parameter (Generic Parameters), a physical uplink control channel common configuration parameter (PUCCH-config common), a physical uplink data channel common configuration parameter (PUSCH-config common), a random access channel common configuration parameter (Rach-config common);
in this embodiment, the target parameters include: configuration parameters of the virtual BWP and configuration parameters of the corresponding BWP in a normal state.
In an embodiment, in the case that the target parameter includes the second set of parameters, further comprising: receiving capability information of setting capability reported by a terminal; performing a configuration parameter restriction operation on the at least two BWPs according to the capability information of the setup capability, wherein the at least two BWPs include a first BWP and a second BWP.
In this embodiment, the setting capability refers to an energy saving capability of the UE in an application scenario of saving energy consumption. According to the capability information of the energy-saving capability, the configuration parameters are limited, so that the configuration parameter ranges of the BWP before and after switching are overlapped, the change of the configuration parameters in the BWP switching process is reduced, the BWP switching efficiency is improved, and the state switching efficiency is further improved.
In this embodiment, in the second set of parameters configured by the RRC, the switching manner between at least two BWPs is dynamic BWP switching.
In the related art, the UE may configure a maximum of 4 uplink BWPs and 4 downlink BWPs per carrier. At the same time, each UE can only have one active uplink BWP and one active downlink BWP. The configuration on each BWP may be different and the UE may dynamically adjust the activation BWP according to the traffic situation. For example, the UE configures 2 downlink BWPs: the bandwidth of BWP1 is less than the bandwidth of BWP 2. In case that downlink traffic of the UE is large, BWP2 may be activated for downlink traffic transmission, and in case that downlink traffic of the UE is small, BWP2 may be switched to save energy consumption. There are three main ways to switch BWP: 1) DCI switching, wherein UE determines a switching target uplink BWP and a switching target downlink BWP according to DCIformat 0_1 and a bandwidth part indication domain in DCIformat 1_ 1; 2) RRC signaling switching, wherein the UE determines a target uplink BWP and a target downlink BWP to be switched according to the firstActiveUpplinkBWP-Id and the firstActiveDownlinkBWP-Id in the RRC signaling; 3) switching a BWP inactivity timer (inactivity timer), and after the inactivity timer of the UE is overtime, switching the downlink BWP to a default downlink BWP by the UE, namely switching to the downlink BWP with the BWP ID of defaultDownlinkBWP-Id. In this embodiment, the switching manner between at least two BWPs may be DCI switching. In one embodiment, the configuration parameter limiting operation includes at least one of: BWP Configuration parameter restricting operation, reference signal Configuration parameter restricting operation, antenna port Configuration parameter restricting operation, SRS antenna switching Configuration parameter restricting operation, and Transmission Configuration Indication (TCI) State (State) Configuration parameter restricting operation.
In one embodiment, the BWP configuration parameter limiting operation comprises: the frequency domain positions of the first BWP and the second BWP are constrained to overlap, wherein the bandwidth of the first BWP is smaller than the bandwidth of the second BWP. In this embodiment, a maximum of 4 BWPs can be set.
Fig. 2 is a schematic diagram of BWP configuration parameter limiting operation according to an embodiment. In this embodiment, two BWPs are configured by RRC, as shown in fig. 2, frequency domain positions of the first BWP and the second BWP overlap, where a diagonal line region is the first BWP, an outermost square block represents the second BWP, and a bandwidth of the first BWP is smaller than a bandwidth of the second BWP.
Fig. 3 is a diagram illustrating another BWP configuration parameter limiting operation according to an embodiment. In this embodiment, three BWPs are configured by RRC, as shown in fig. 3, a vertical line region represents a first BWP, a diagonal line region represents a second BWP, and an outermost box represents a third BWP, where frequency domain positions of the first BWP, the second BWP and the third BWP are overlapped, where a bandwidth of the first BWP is smaller than a bandwidth of the second BWP, and a bandwidth of the second BWP is smaller than a bandwidth of the third BWP.
In one embodiment, the reference signal configuration parameter limiting operation includes: the time-frequency domain positions of the reference signals of the first BWP are restricted to a subset of the time-frequency domain positions of the reference signals of the second BWP. The reference signal includes at least one of: channel State Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Sounding Reference Signal (SRS), demodulation Reference Signal (De-Modulation Reference Signal, DMRS), Phase-Tracking Reference Signal (PTRS), Aperiodic Tracking Reference Signal (a-TRS), Aperiodic Channel State Reference Signal (a-CSI-RS), and Semi-Persistent Channel State Reference Signal (SPS-CSI-RS). In an embodiment, the antenna port configuration parameter limiting operation comprises: the number of antenna ports of the first BWP is limited to be less than or equal to the number of antenna ports of the second BWP. The antenna port includes at least one of: PDCCH antenna port, PDSCH antenna port, CSI-RS antenna port, synchronization signal broadcast channel antenna port (SS/PBCH), PUSCH antenna port, PUCCH antenna port, DMRS antenna port, SRS antenna port, PRACH antenna port (physical random access channel); for example, the CSI-RS antenna ports of the second BWP configuration are 2 ports, 3000 and 3001 respectively, and the CSI-RS antenna ports of the first BWP configuration can only be 1 port (3000) or 2 ports (3000 and 3001);
in one embodiment, the TCI state configuration parameter limiting operation includes: sharing the TCI state of the first BWP and the second BWP.
In an embodiment, the SRS antenna switching configuration parameter restriction operation includes: the SRS antenna switching configuration parameters of the first BWP are restricted to a subset of the SRS antenna switching configuration parameters of the second BWP.
In an embodiment, the setting capability is determined according to at least one of a terminal type and frequency band information. In the present embodiment, the frequency band information may be the FR frequency range 1 or the FR frequency range 2.
The above embodiment limits the configuration parameters to overlap the configuration parameter ranges of the BWPs before and after the switch, thereby reducing the change of the configuration parameters during the BWP switch process, improving the BWP switch efficiency, and further improving the state switch efficiency.
In an embodiment, the BWP configuration parameter limiting operation described above is also applicable to application scenarios of BWP handover. In the process of switching the BWP, the switching between the dormant state and the normal state of the UE is not considered, the configuration parameters of the BWP are limited according to the setting capability of the UE, and the range overlapping of the configuration parameters of the BWP before and after the switching is limited, so that the change of the configuration parameters in the process of switching the BWP is reduced, and the BWP switching efficiency is improved.
In one embodiment, the BWP configuration parameter limiting operation described above is only performed during dynamic BWP handoff.
The embodiment of the application also provides a switching method which is applied to terminals such as UE. Fig. 4 is a flowchart of a handover method according to an embodiment.

In step 210, a control message is received, the control message including target parameters determined according to configuration parameters of the RRC.
In step 220, the sleep state and the normal state are switched according to the target parameter.
For example, when the target parameter indicated by the serving node is the first set of configuration parameters, the UE changes the monitoring period of the PDCCH according to the target parameter and monitors the PDCCH according to the offset indicated by the target parameter, if the indicated monitoring period is greater than the current monitoring period of the UE, the UE switches to the dormant state, and if the indicated monitoring period is less than the current monitoring period of the UE, the UE switches to the normal state. And under the condition that the target parameters indicated by the service node are the second set of configuration parameters, the UE can switch from the virtual BWP to the normal BWP according to the target parameters, and the state switching is realized.
In this embodiment, the UE implements state switching according to a target parameter in a control message sent by a serving node by receiving the control message, where the control message is used to indicate the target parameter, and the signaling overhead is small, that is, the method may be applied even when the UE does not have a capability of configuring multiple BWPs, so that the applicability of state switching is improved, and the switching efficiency is improved by efficiently indicating state switching to the terminal.
