Detailed Description
The present application is described below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
The UE monitors PDC at a certain period in a normal state CH while in sleep state the monitoring of PDCCH is stopped, but other activities such as CSI measurement, AGC and BM etc. continue to be performed. The sleep state and the normal state have certain switching time delay, and the switching time delay mainly depends on T activation_time The method comprises the steps of analyzing time delay, radio Frequency (RF) wake-up time delay, AGC adjustment time delay, time Frequency offset synchronization time delay and the like by a media access Control layer Control unit (Medium Access Control-Control Element, MAC-CE). In the case that the UE is in the dormant state, the RF on the Secondary Cell (Scell) is not turned off, so that the handover delay can be reduced.
In the related art, the monitoring period of the UE on the PDCCH can be dynamically modified through the downlink control information (Downlink Control Information, DCI) signaling, the monitoring period in a normal state is relatively short, the monitoring is more frequent, the monitoring period in a dormant state is relatively long, the monitoring is sparse, but the method for dynamically indicating needs to occupy larger signaling overhead and has low 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 technique, which requires the UE to have the capability of configuring the plurality of BWP, but this capability of configuring the plurality of BWP is in the granularity of a band (band), i.e., configuring the plurality of BWP is not supported on some bands, and the method of implementing the UE state switching using the BWP switching technique is not applicable any more through two UE capability notifications of BWP different mathematical physics (BWP-diffnumelog) and BWP identical mathematical physics (BWP-samenulog). The related art method has limitations in terms of signaling overhead or bandwidth limitation, and cannot efficiently indicate handover of the UE between the sleep state and the normal state.
The embodiment provides a handover indication method, which configures parameters through RRC signaling, determines target parameters according to the configuration parameters, and sends the target parameters to a terminal through a control message so as to indicate the terminal to perform state handover, wherein the control message is used for indicating the target parameters to the terminal, signaling overhead is small, the method can be applied even if the UE does not have the capability of configuring a plurality of BWPs, the applicability of state handover is improved, and the handover efficiency is improved by efficiently indicating the 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, a target parameter is determined according to 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 state switching includes switching from a sleep state to a normal state, and switching from the normal state to the sleep 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 types of PDCCH monitoring periods are configured on the Scell, one long period is a short period, the long period corresponds to a dormant state, and the short period corresponds to a normal state, and then the UE may be further instructed to switch the PDCCH monitoring period through a control message, for example, 1 bit is used for switching the PDCCH monitoring period on one Scell, if the bit is configured as 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 of the handover, e.g., to configure the BWP of the sleep state and the BWP of the normal state, to further instruct the UE to switch from the BWP of the sleep state to the active BWP by the control message, thereby enabling the handover from the sleep state to the normal state, or to further instruct the UE to switch from the active BWP to the BWP of the sleep state by the control message, thereby enabling the handover from the normal state to the sleep state. The configuration parameters can be one set or a plurality of sets, and the service node can determine 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 a sleep state and a 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 whether to monitor the PDCCH in each secondary cell, or to switch a monitoring period and offset of the monitoring PDCCH, etc. The method of this embodiment does not require that the UE must have the capability of configuring multiple BWP, and the control message is only used to indicate the target parameter, so that signaling overhead is small.
In an 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 BWP, wherein at least one BWP corresponds to a sleep state.
In an embodiment, two sets of configuration parameters may be configured by RRC, where the first set of configuration parameters is used to indicate a monitoring period of the UE on the PDCCH and an offset, where the offset is used to indicate a slot position monitored in one monitoring period, for example, one monitoring period includes 10 slots, and the offset is 3, and the 3 rd slot in the 10 slots in the monitoring period monitors the PDCCH. The second set of configuration parameters includes at least two BWP, wherein at least one BWP is in a dormant state, and the second set of configuration parameters is indicated to the UE as target parameters, whereby the UE can implement state switching through BWP switching.
In an embodiment, the determining the target parameter according to the configuration parameter of the radio resource control RRC includes: selecting a target parameter from the first set of parameters and the second set of parameters according to at least one of the following information: band information, terminal capability information, new air interface NR version information supported by a service node or a terminal, and Scell activation delay requirement information.
In the process of indicating the state switching to the terminal, the service node may select one set of configuration parameters from the two sets of configuration parameters as a target parameter, for example, in the case that the UE has the capability of configuring a plurality of BWP in the current frequency band and supports BWP switching, the second set of configuration parameters may be selected as the target parameter, otherwise, the first set of configuration parameters may be selected as the target parameter. For another example, in the case where the UE has a low latency requirement service, the latency 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 includes a target parameter indication field; the bit number 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 corresponds to one auxiliary cell; where m represents 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 the case that the service 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, and the target parameter indication field is used for indicating the switching of the different PDCCH monitoring periods and offsets; in case the serving node selects the second set of configuration parameters as target parameters, e.g. the gNB configures the Scell with a plurality of BWPs, the target parameter indication field is used to indicate a handover of a different BWP.
In an embodiment, the target parameters of m-1 secondary cells may be indicated by m-1 bits, each bit corresponding to one secondary cell, respectively; 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 (Power save) application scenario may be used.
In an embodiment, the configuration parameters include configuration parameters of a virtual BWP; the virtual BWP corresponds to a BWP in a normal state, and the first configuration parameter is different between the virtual BWP and the BWP in the normal state; the virtual BWP is identical with the second configuration parameter between the corresponding BWP in the normal state.
In this embodiment, the serving node configures configuration parameters of the virtual BWP through RRC and sends the configuration parameters to the UE, where the virtual BWP is bound with one BWP in a normal state, and the two BWP in the configuration binding are equivalent to configuring only one BWP, but part of the configuration parameters (the second configuration parameters) of the two BWP are the same, and part of the configuration parameters (the first configuration parameters) are different, so that the switching efficiency between the two BWP is improved. Indicating the configuration parameters of the virtual BWP and the corresponding BWP in the normal state to the UE through the control message may enable the UE to switch from the sleep state to the normal state by switching from the virtual BWP to the BWP in the normal state or may indicate the UE to switch from the normal state to the sleep state by switching from the BWP in the normal state to the virtual BWP.
In an embodiment, the first configuration parameter comprises at least one of: search space of PDCCH, control resource set (Control Resource Set, core) configuration parameters, channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS) configuration parameters, aperiodic tracking Reference Signal (Aperiodic Tracking Reference Signal A-TRS, a-TRS) configuration parameters, sounding Reference Signal (Sounding Reference Signal, SRS) configuration parameters, BM configuration parameters.
In an embodiment, the second configuration parameter comprises at least one of: bandwidth, subcarrier spacing (Subcarrier Spacing, SCS) and center frequency point.
In one embodiment, the BWP is the same as the BWP Index (ID) of the corresponding BWP in the normal state.
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 proprietary parameters and its sub-parameters between the first BWP and the second BWP may be configured differently, and the common parameters are the same. For example, the BWP-specific parameters include at least one of: physical downlink shared channel configuration parameters (Physical Downlink Shared Channel-configuration, PDSCH-configuration), physical downlink control channel configuration parameters (PDCCH-configuration), semi-persistent transmission configuration parameters (Semi-Persistent Scheduling-configuration, SPS-configuration), radio link listening configuration parameters (Radio Link Monitoring-configuration), physical uplink data channel configuration parameters (PUSCH-configuration), physical uplink control channel configuration parameters (PUCCH-configuration), configuration Grant configuration parameters (Configured Grant-configuration), sounding reference signal configuration parameters (SRS-configuration), beam failure recovery configuration parameters (Beam Failure Recovery-configuration); the BWP common parameter includes at least one of: physical downlink control channel common configuration parameters (PDCCH-config common), physical downlink data channel common configuration parameters (PDSCH-config common), general parameters (Generic Parameters), physical uplink control channel common configuration parameters (PUCCH-config common), physical uplink data channel common configuration parameters (PUSCH-config common), random access channel common configuration parameters (Rach-config common);
In this embodiment, the target parameters include: configuration parameters of the virtual BWP and configuration parameters of the corresponding BWP in the normal state.
In an embodiment, in case the target parameters comprise a second set of parameters, further comprising: receiving capability information of setting capability reported by a terminal; and performing configuration parameter limiting operation on the at least two BWPs according to the capability information of the setting capability, wherein the at least two BWPs comprise 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 where energy consumption is saved. According to the capability information of the energy saving capability, the configuration parameter ranges of BWP before and after switching are overlapped by limiting the configuration parameter, so that the change of the configuration parameter 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 of the RRC configuration, the switching manner between at least two BWP is dynamic BWP switching.
In the related art, the UE may configure up to 4 uplink BWP and 4 downlink BWP on each carrier. Each UE can only have one active upstream BWP and one active downstream BWP at the same time. The configuration on each BWP may be different and the UE may dynamically adjust the active BWP according to the traffic situation. For example, the UE configures 2 downlink BWP: BWP1 bandwidth is smaller than BWP2 bandwidth. In case of a large downlink traffic volume of the UE, BWP2 may be activated for downlink traffic transmission, and in case of a small downlink traffic volume of the UE, switching to BWP2 may be performed to save energy consumption. There are three main ways of switching BWP: 1) DCI switching, wherein the UE determines a target uplink BWP and a target downlink BWP for switching according to the bandwidth part indication domains in DCI formats 0_1 and 1_1; 2) RRC signaling is switched, and the UE determines a target uplink BWP and a target downlink BWP of the switching according to the first ActiveUpLinkBWP-Id and the first ActiveDownlinkBWP-Id in the RRC signaling; 3) BWP inactivity timer (inactivity timer) switches, when the UE's inactivity timer expires, the UE switches downlink BWP to default downlink BWP, i.e. to downlink BWP with BWP ID of defaultDownlinkBWP-ID. In this embodiment, the switching manner between at least two BWP may be DCI switching. In one embodiment, the configuration parameter limiting operation includes at least one of: BWP configuration parameter limitation operation, reference signal configuration parameter limitation operation, antenna port configuration parameter limitation operation, SRS antenna switching configuration parameter limitation operation, and transmission configuration indication (Transmission Configuration Indicator, TCI) State configuration parameter limitation operation.

In this embodiment, at most 4 BWP may be provided.
Fig. 2 is a schematic diagram illustrating BWP configuration parameter limitation operation according to an embodiment. In this embodiment, two BWP are configured through RRC, as shown in fig. 2, where the frequency domain positions of the first BWP and the second BWP overlap, the diagonal line area is the first BWP, the outermost box indicates the second BWP, and the bandwidth of the first BWP is smaller than that of the second BWP.

In this embodiment, three BWP are configured by RRC, as shown in fig. 3, the vertical line area indicates the first BWP, the diagonal line area indicates the second BWP, and the outermost box indicates the third BWP, where the frequency domain positions of the first BWP, the second BWP and the third BWP overlap, and the bandwidth of the first BWP is smaller than the bandwidth of the second BWP, and the bandwidth of the second BWP is smaller than the 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 limited to a subset of the time-frequency domain positions of the second BWP reference signals. The reference signal includes at least one of: channel state Reference signals (CSI-RS), tracking Reference signals (Tracking Reference Signal, TRS), sounding Reference Signals (SRS), demodulation Reference signals (De-Modulation Reference Signal, DMRS), phase tracking Reference signals (Phase-tracking Reference Signal, PTRS), aperiodic tracking Reference signals (a-TRS), aperiodic channel state Reference signals (Aperiodic-Channel State Information-Reference Signal, a-CSI-RS), and Semi-persistent channel state Reference signals (Semi-Persistent Scheduling-Channel State Information-Reference Signal, SPS-CSI-RS). In one embodiment, the antenna port configuration parameter limiting operation includes: 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, if the CSI-RS antenna ports of the second BWP configuration are 2 ports, 3000 and 3001 respectively, the CSI-RS antenna ports of the first BWP configuration can only be 1 port (3000) or 2 port (3000 and 3001);

In an embodiment, the setting capability is determined according to at least one of a terminal type and band information. In the present embodiment, the band information describes that it may be FR frequency range 1 or FR frequency range 2.
The embodiment of the invention enables the range of the configuration parameters of BWP before and after the switching to overlap by limiting the configuration parameters, thereby reducing the change of the configuration parameters in the BWP switching process, improving the BWP switching efficiency and further improving the state switching efficiency.
In an embodiment, the BWP configuration parameter limitation operation described above is also applicable to the application scenario of BWP handover. In the BWP switching process, the configuration parameters of the BWP are limited according to the setting capability of the UE without considering the switching between the sleep state and the normal state of the UE, and the configuration parameter range overlapping of the BWP before and after the switching is limited, so as to reduce the configuration parameter variation in the BWP switching process, thereby improving the BWP switching efficiency.
In one embodiment, the BWP configuration parameter limitation operation is performed only during dynamic BWP switching.

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