Description

User equipment motion state estimation method and user equipment

This application claims priority to Chinese Patent Application No. 201210016137.7, entitled "A User Equipment Motion State Estimation Method and User Equipment", filed on January 18, 2012, the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to the field of wireless communications, and in particular, to a method for estimating a motion state of a user equipment and a user equipment. Background technique

In the field of wireless communication, how to effectively estimate the motion state of User Equipment (UE) has always been an important issue for researchers. In the existing protocol, the commonly used UE motion state estimation method is to determine that the UE is in a high-speed motion state according to the cell reselection when the UE is in the idle state (IDLE) and/or the cell handover count value when the UE is in the connected state (Connect). , or at medium speed, or at low speed. Among them, the estimation method can be briefly summarized as follows:

Step 1: The base station apparatus according to the current estimated parameters a set of network configuration information transmitting motion to the UE, including _{_{_{N CR - H, N CR -}}} M, T CR Korea to hide T _CR, wherein, Nd represents a first width count value, M Indicates the second count threshold, H — _{H >} N _CR — _M T _CR丽 , 丽 , both represent time periods, and T _{CR maxHyst} > T _{CR max} . Step 2: After receiving the foregoing motion state estimation parameters, the UE counts cell reselection and/or cell handover. The UE may be in an idle state for a long time during the motion. In this case, only the cell reselection is counted. The UE may also be in a connected state for a long time during the motion. In this case, only the cell handover needs to be counted. Of course, the UE may be in the connected state after being in the idle state during the motion. In this case, both the cell reselection and the cell handover need to be counted.

Step 3: The UE performs a motion state decision. If the calculated value of the UE N ≥ N _{CR Η} within the length of time _max , it is determined that the UE is in a high-speed motion state; if the UE count value N _CR _ _M < N < N _CR _ _H , then the UE is judged to be in the medium speed motion state; if it is judged that the UE is neither in the high speed motion state nor in the medium speed motion state, and the time interval ^ ^ is maintained The result of the decision determines that the UE is in a low speed motion state.

In practice, it is found that the UE performs cell reselection or cell handover, which is not triggered by the UE motion. It may be that the network requests the UE to perform cell reselection or cell handover for the purpose of load balancing, and may also be caused by the UE access permission change. The connection between the UE and the serving cell is interrupted and has to be switched to other cells, etc., and the cell reselection or cell handover triggered by these non-UE motions, once included in the decision count, will result in an increase in the decision error of the UE motion state. In addition, in some special application scenarios, such as in heterogeneous networks (including Coordinated Multiple Points (COMP) scenario 4 in Enhanced Long Term Evolution Advanced (LTE-A)), The cell identifier of the cell or the micro cell is the same, and when the UE moves from one cell to another cell, it is not classified into cell reselection or cell handover, which also reduces the UE decision count, thereby causing the UE to The decision error of the motion state increases.

All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without the creative work are all within the scope of the present invention.

The embodiment of the invention provides a UE motion state estimation method and related device, which can improve the decision accuracy of the UE motion state. The details are described below separately.

Embodiment 1:

Referring to FIG. 1, FIG. 1 is a flow chart of a UE motion state estimation method according to Embodiment 1 of the present invention.

101. The UE accumulates a sum N of weighting values of valid changes of each cell in the first time period T1. The valid change of the cell includes cell reselection and/or cell handover triggered by UE motion.

102. The UE determines the motion state according to the size of N.

For example, the UE may determine that the UE is in a high-speed motion state when N is greater than or equal to N _CR — _H ; N _CR — _M ^ < N _{CR H} ^ , and then determine that the UE is in a medium-speed motion state. If the UE decides that it is neither in the high speed motion state nor in the medium speed motion state, and the decision result is maintained for the second time period T2, the UE may determine that it is in the low speed motion state; wherein, T2>T1.

In the first embodiment of the present invention, the sum of the weighted values of the cell reselection and/or the cell handover triggered by the UE motion in the first time period T1 may be accumulated, and the UE motion state is determined according to the sum of the weighted values obtained by counting. In the embodiment of the present invention, the sum of the weighted values of the cell reselection and/or the cell handover triggered by the UE motion can be obtained in the homogeneous network or the heterogeneous network, thereby effectively improving the decision accuracy of the UE motion state.

Embodiment 2:

Referring to FIG. 2, FIG. 2 is a flowchart of a UE motion state estimation method according to Embodiment 2 of the present invention. The second embodiment of the present invention is to describe the UE motion state estimation method provided by the embodiment of the present invention from the perspective of the UE. For the UE, it may be in an idle state for a long time during the motion, or may be in a connected state for a long time, or may be in an idle state first, and then in a connected state. Therefore, the UE may reselect the cell triggered by its motion within a certain period of time (the UE is in an idle state) and

The weighting values of the cell handover (the UE is in the connected state) are all counted, and the sum of the weighted values obtained by the counting is compared with the motion state estimation parameter configured by the base station, thereby estimating the motion state. After estimating the UE motion state, the UE may select a corresponding cell reselection parameter according to the UE motion state for UE cell reselection, or select a corresponding cell handover parameter for UE cell handover. As shown in FIG. 1, the UE motion state estimation method may include the following steps:

201. The UE receives a set of motion state estimation parameters sent by the base station device, where the motion state estimation parameter includes a first count threshold W _C ― ^, a second count threshold N _c « _—M , a first time period T1, and a Two time periods T2; wherein, N _CR — _{H >} N _CR — _M T2> T1. The foregoing motion state estimation parameter may be pre-configured by the base station device according to a Long Term Evolution (LTE) protocol, and the base station device may flexibly perform the foregoing motion state estimation parameter according to related factors such as a source cell size and a communication environment. Configuration. For example, in a simulation, the base station equipment can be configured with =9, N _CR _ _M =3, Tl=120s, and T2=6min. The specific value of the motion state estimation parameter is not limited in the embodiment of the present invention.

202. The UE user equipment accumulates the sum N of the weighting values of the effective changes of the cells in the T1, where the cell effective change includes the cell reselection and/or the cell handover triggered by the UE motion.

For example, if the UE is in the idle state, and the UE meets the cell reselection condition, but the signal quality of the source cell does not change significantly within the specified time window, it indicates that the secondary cell reselection is triggered by the non-UE motion. the UE may give the secondary cell reselection flag marked A- _RA = 0, to indicate that the secondary cell reselected cell non-active change (i.e., the non-secondary cell reselection triggered UE movement), the secondary cell reselection weight value The judgment count of the UE motion state is not included; otherwise, if the signal quality variation of the source cell is greater than the threshold within the specified time window (ie, the signal quality of the source cell changes significantly within the specified time window), then the The secondary cell reselection is triggered by the UE motion. At this time, the UE may mark the secondary cell reselection with the flag A _ra & / = i to indicate that the secondary cell reselection is a valid cell change (that is, the secondary cell reselection is performed by the UE. The motion-triggered value of the secondary cell reselection will be included in the decision count of the UE motion state.

For example, if the UE is in the connected state, and the base station device notifies the UE to perform the cell handover, but the signal quality of the source cell does not change significantly within the specified time window, it indicates that the secondary cell handover is When the non-UE motion is triggered, the UE may mark the secondary cell handover with a flag Is valid = 0 to indicate that the secondary cell handover is a non-cell effective change (ie, the secondary cell handover is triggered by non-UE motion), the secondary cell The weighted value of the handover is not included in the judgment count of the UE motion state; otherwise, if the signal quality variation of the source cell is greater than the threshold within the specified time window (ie, the signal quality of the serving cell changes significantly within the specified time window) If the cell handover is triggered by the UE motion, the UE may mark the secondary cell handover with the flag A _ra & / = i to indicate that the secondary cell handover is a valid cell change (that is, the secondary cell handover is performed by the UE). The motion-triggered value of the secondary cell handover will be included in the decision count of the UE motion state.

The weighted value of each cell reselection in the first time period T1 and/or the weighted value of the cell handover may be accumulated to obtain the sum N of the weighted values of the cell reselection and/or the cell handover triggered by the UE motion.

The threshold value or the specified time window may be sent by the base station device to the UE. For example, the base station device passes the threshold or the specified time window by using Radio Resource Control (RRC) signaling or media access control (Media Access). Control, MAC) The CE signaling or the broadcast message is sent to the UE. Alternatively, the threshold or the specified time window may be pre-stored by the UE, which is not limited in the embodiment of the present invention. In the embodiment of the present invention, when the UE finds that the cell reselection or the cell handover condition is met, the signal quality of the source cell may be measured within a specified time window, thereby obtaining a signal quality change amount of the source cell in the specified time window. In the embodiment of the present invention, the signal quality of the source cell may be represented by RSRP (Reference Signal Received Power) or RSRQ (Reference Signal Receive Quality) or Channel State Information Reference Signal (CSI-RS).

In the embodiment of the present invention, the cell reselection triggered by the common non-UE motion includes, but is not limited to, the cell reselection triggered by the channel quality of the inter-frequency high-priority cell or the hetero-system cell; the common non-UE motion triggering The cell handover includes, but is not limited to, a cell handover triggered by the network for load balancing or UE access permission change, or the network switches the UE from a pico cell to a macro cell.

In the embodiment of the present invention, the weighting value of the cell reselection triggered by the UE motion may be related to the cell reselection type, and the weighting value of the cell handover triggered by the UE motion may also be related to the cell handover type. For example, if the cell reselection type or the cell handover type triggered by the UE motion is a macro cell (Macro cell) -> Macro cell, then the weight of the cell reselection or cell handover triggered by the UE motion may be 1. If the cell reselection type or the cell handover type triggered by the UE motion is a macro cell -> a pico cell, the weight of the cell reselection or the cell handover triggered by the UE motion may be 0.4, The effect of increasing the weighted value count of cell reselection or cell handover caused by the heterogeneous network is reduced. The weighting value of the cell reselection that is related to the cell reselection type, and the weighting value of the cell handover that is related to the cell handover type may be sent by the base station device by using RRC signaling or MAC CE signaling or a broadcast message. The UE is pre-stored by the UE, which is not limited by the embodiment of the present invention. Certainly, the embodiment of the present invention may also consider the cell reselection type or the cell handover type as the cell reselection or the cell handover triggered by the UE motion, and consider the weighting value as 1 or other plus fixed value. Not limited. In the embodiment of the present invention, when the weighting values of the cell reselection and/or the cell handover are both 1, the sum of the weighting values may be regarded as the sum of the times of cell reselection and/or cell handover.

203. The UE compares the sum N of the weighted values accumulated in T1 with the motion state estimation parameter, and determines the UE motion state.

Wherein, if the sum N of the weighted values accumulated in T1 is greater than or equal to _C?, the UE can determine that it is in a high-speed motion state; if N _CR — _M ^<N _CR — _H , the UE determines that it is in the medium-speed motion. status.

In an embodiment, if the UE determines in T1 that it is neither in the high-speed motion state nor in the medium-speed motion state, the UE may extend T1 to T2, if any length in T2 is within the T1 time period, the UE - The UE is judged to be in a low speed motion state while maintaining the state of being neither in the high speed state nor in the medium speed state.

In the second embodiment of the present invention, the weighting values of the cell reselection and/or the cell handover triggered by the UE motion may be counted, and the sum of the weighted values obtained by the counting is compared with the motion state estimation parameter configured by the base station. Thereby the UE motion state is estimated. In the embodiment of the present invention, the sum of the weighted values of the cell reselection and/or the cell handover triggered by the UE motion can be obtained in the homogeneous network or the heterogeneous network, thereby effectively improving the decision accuracy of the UE motion state.

Embodiment 3:

Referring to FIG. 3, FIG. 3 is a flow chart of a UE motion state estimation method according to Embodiment 3 of the present invention. Cheng Tu. The third embodiment of the present invention describes a UE motion state estimation method provided by an embodiment of the present invention from the perspective of a UE. The UE motion state estimation method provided in Embodiment 3 of the present invention is applicable to a heterogeneous network such as a multipoint collaboration (COMP) scenario 4. In a heterogeneous network, a plurality of access points (APs) are generally provided in the coverage of the macro base station, and these APs are used to provide a small range of wireless coverage, which can be regarded as micro cells, and these APs and macro base stations The same identity can be shared. In the third embodiment of the present invention, if the source access point AP changes, and the signal quality change of the reference signal corresponding to the source access point AP is greater than the threshold in the specified time window, the UE performs a hidden Sexual cell reselection or cell handover. At this time, the cell reselection refers to the reselection of the source access point AP to the second AP or the source access point AP to the cell, and the cell handover substantially refers to the source access point AP to the second AP or the source access. Point AP to cell handover. The source access point AP to the second AP may include a source AP to a second AP of the same cell, or a source AP to a second AP of another cell. The secondary cell reselection or cell handover may be regarded as a primary cell effective change, and the secondary cell reselection or cell handover needs to be included in the weighted value count. The change of the source access point AP includes: changing a reference signal port of the source access point AP, or changing a reference signal configuration of the source access point AP. The reference signal includes, but is not limited to, a Channel-State Information Reference Signal (CSI-RS) or a Cell-specific Reference Signal (CRS). As shown in FIG. 3, the UE motion state estimation method may include the following steps:

301. The UE receives a set of motion state estimation parameters sent by the base station device, where the motion state estimation parameter includes a first count threshold W _{C ′} ^, a second count threshold N _c « _—M , a first time period T1, and a first Two time periods T2; wherein, N _CR — _{H >} N _CR — _M Τ 2> Τ 1.

302. The UE determines, in T1, whether each cell reselection or cell handover is triggered by the UE motion. If yes, the secondary cell reselection or cell handover is used as a valid change of the cell, and the weighted value of the valid change of each secondary cell is accumulated. The sum of N.

For example, if the UE is in an idle state, the source access point AP changes, and the signal quality change of the reference signal corresponding to the source access point AP is greater than the threshold in the specified time window, The cell reselection is triggered by the UE motion. At this time, the UE may mark the secondary cell reselection with Is_valid=1, indicating that the secondary cell reselection is a valid cell change (ie, the secondary cell reselection is performed by the UE. The triggering of the cell reselection will be included in the judgment count of the UE motion state. For example, if the source access point AP changes in the connected state, and the signal quality change of the reference signal corresponding to the source access point AP is greater than the threshold in the specified time window, The secondary cell handover is triggered by the UE motion. At this time, the UE may mark the secondary cell handover with the flag Is_valid = \ to indicate that the secondary cell handover is a valid cell change (that is, the secondary cell handover is triggered by the UE motion). The weighting value of the secondary cell handover will be included in the decision count of the UE motion state.

In the embodiment of the present invention, the cell reselection triggered by the common non-UE motion includes, but is not limited to, the cell reselection triggered by the channel quality of the inter-frequency high-priority cell, and the UE that is in the idle state due to the load balancing consideration. Reselecting from a macro cell to a pico cell or a lightly loaded cell; common non-UE motion triggered cell handovers include, but are not limited to, cell handovers triggered by load balancing or UE access rights changes. The network switches the UE from a macro cell to a pico cell or the like.

In the embodiment of the present invention, the weighting value of the cell reselection triggered by the UE motion may be related to the cell reselection type, and the weighting value of the cell handover triggered by the UE motion may also be related to the cell handover type. For example, if the cell reselection type or the cell handover type triggered by the UE motion is a macro cell -> a Pico cell, the weight of the cell reselection or the cell handover triggered by the UE motion may be Is 1. If the cell reselection type or the cell handover type triggered by the UE motion is a Pico cell -> Macro cell, the weight of the cell reselection or cell handover triggered by the UE motion may be 0.4, The effect of increasing the weighted value count of cell reselection or cell handover caused by the heterogeneous network is reduced. The weighting value of the cell reselection that is related to the cell reselection type, and the weighting value of the cell handover that is related to the cell handover type may be sent by the base station device by using RRC signaling or MAC CE signaling or a broadcast message. The UE is pre-stored by the UE, which is not limited by the embodiment of the present invention. Certainly, the embodiment of the present invention may also consider the cell reselection type or the cell handover type as the cell reselection or the cell handover triggered by the UE motion, and consider the weighting value as 1 or other plus fixed value. Not limited.

303. The UE compares the sum N of the weighted values accumulated in T1 with the motion state estimation parameter, and determines the UE motion state. Wherein, if the sum N of the weighted values accumulated in T1 is greater than or equal to W _{C ?} , the UE can determine that it is in a high-speed motion state; if N _CR — _M ^ < N _CR — _H , the UE determines that it is at a medium speed Movement state.

In the third embodiment of the present invention, the weighting values of the cell reselection and/or the cell handover triggered by the UE motion may be counted, and the sum N of the weighted values obtained by the counting is compared with the motion state estimation parameter configured by the base station. Thereby the UE motion state is estimated. In the heterogeneous network such as the COMP scenario 4, the sum of the weighted values of the cell reselection and/or the cell handover triggered by the UE motion can be obtained, so that the decision accuracy of the UE motion state can be effectively improved.

As an optional implementation manner, in the embodiment of the present invention, each cell reselection or cell handover includes an AP reselection or an AP handover. Specifically, the AP reselection includes the source access point AP to the second AP or the source access point. AP to cell reselection; AP handover includes handover from source access point AP to second AP or source access point AP to cell. The source access point AP to the second AP may include a source AP to a second AP of the same cell, or a source AP to a second AP of another cell. The weighted value of AP reselection or AP switching can be included in the decision count. The UE may also determine, in the first time period T1, whether each cell reselection including AP reselection or each cell handover including AP handover is triggered by a change of the source access point AP, and if yes, the time may be The weighted value of cell reselection or cell handover is included in the decision count. The change of the source access point AP may be represented by a change in the reference signal port of the characterization source access point AP, or by a change in the configuration of the reference signal characterization of the source access point AP. The reference signal may be a CSI-RS signal or a CRS signal or the like.

Referring to FIG. 4, FIG. 4 is a flow chart of a UE motion state estimation method according to Embodiment 4 of the present invention.

401. The first base station receives the user equipment history information sent by the second base station, where the user equipment history information includes the indication information of the previous handover of the UE, and the camping time At of the source cell before the previous handover of the UE. The information is used to indicate whether the handover is triggered by UE motion. 402. The first base station determines, according to user equipment history information sent by the second base station, a UE motion state.

For example, the first base station may accumulate the camping time At included in the set time period T according to the user equipment history information sent by the second base station, thereby determining all the handovers in the time T, and according to the previous handover of the UE. The indication information selects a handover triggered by the UE motion, and calculates a sum N of weighting values of the respective handovers triggered by the UE motion; and determines the UE motion state according to the magnitude of N.

In the embodiment of the present invention, the sum of the weighted values of the cell handover triggered by the UE motion can be obtained in the homogeneous network or the heterogeneous network, so that the decision accuracy of the UE motion state can be effectively improved.

Embodiment 5:

Referring to FIG. 5, FIG. 5 is a flow chart of a UE motion state estimation method according to Embodiment 5 of the present invention. The fifth embodiment of the present invention describes a UE motion state estimation method according to an embodiment of the present invention from the perspective of a base station device. In the method shown in Figure 5, the UE is required to be in a connected state. As shown in FIG. 5, the UE motion state estimation method may include the following steps:

501. The target base station receives the UE history information sent by the original base station, and the UE history information is that the original base station decides to switch its UE to the target base station and sends the message to the target base station. The UE history information includes at least the indication information of the previous handover of the UE. And the camping time At the source cell before the previous handover of the UE; the indication information of the previous handover of the UE is used to indicate whether the handover is triggered by the UE motion.

In the embodiment of the present invention, after the UE transitions from the idle state to the connected state, the source cell starts to record the camping time At of the source cell in the UE.

As an optional implementation manner, the indication information of the previous handover of the UE may include whether the signal quality change amount of the source cell is greater than a threshold value in the specified time window when the UE successively switches. If the signal quality change of the source cell is greater than the threshold in the specified time window, it indicates that the handover is triggered by the UE motion; conversely, it indicates that the handover is triggered by the non-UE motion.

For example, the UE is in the connected state, and the original base station notifies the UE to perform the cell handover, but the signal quality of the source cell does not change significantly within the specified time window, and the sub-cell handover is triggered by the non-UE motion. The base station may mark the secondary cell switch with a flag Is valid = 0 to indicate the The secondary cell handover is triggered by the non-UE motion, and the weighted value of the secondary cell handover is not included in the judgment count of the UE motion state; otherwise, if the signal quality change amount of the source cell is greater than the threshold in the specified time window, the time is The cell handover is triggered by the UE motion. At this time, the original base station may mark the secondary cell handover with the flag A _ra & / = i to indicate that the secondary cell handover is triggered by the UE motion, and the weight value of the secondary cell handover will be included in the UE. The judgment count of the motion state.

The set time period T of the target base station may include multiple dwell times At. By counting the dwell time At included in the set time period T, all the handovers occurring within the set time period T can be determined, and the handover triggered by the UE motion is determined from the handovers according to the indication information of the previous handover of the UE. The handover is triggered by the UE standby motion within the time period T, and the weighting values of these handovers are counted.

In an embodiment, the UE history information sent by the source base station may further include an identifier and/or a size type (ie, a radius size) of the source cell when the UE is switched, so that the target cell can learn the previous handover type of the UE, and then according to the UE history. The handover type determines the weighting value of the previous handover of the UE. As a matter of course, the embodiment of the present invention can also be used as the cell switching type, and the weighting value is regarded as 1 or other fixed value as long as the cell switching is triggered by the UE motion, which is not limited in the embodiment of the present invention.

503. The target base station determines when the sum of the weighted values N is greater than or equal to the first count threshold ^

The UE is in a high speed motion state, or when the second count threshold W _c «- MN <W _{C ?} — ^, the UE is judged to be in a medium speed motion state; otherwise, the UE is judged to be in a low speed motion state.

In the fifth embodiment of the present invention, the target base station may count the weighted values of the cell handover triggered by the UE motion, and compare the sum of the weighted values obtained by the counting with the motion state estimation parameters configured by the target base station, thereby estimating the UE. Movement state. In the embodiment of the present invention, the sum of the weighted values of the cell handover triggered by the UE motion can be obtained in the homogeneous network or the heterogeneous network, so that the decision accuracy of the UE motion state can be effectively improved.

The sixth embodiment of the present invention is to describe a UE motion state estimation method according to an embodiment of the present invention from the perspective of a base station device. In the method shown in Figure 6, the UE is in a connected state. Wherein the invention is implemented The UE motion state estimation method provided in Example 6 is applicable to a heterogeneous network such as a multipoint cooperation (COMP) scenario 4. In a heterogeneous network, a plurality of APs are generally provided in the coverage of the macro base station. These APs are used to provide a small range of wireless coverage, and can be regarded as micro cells. These APs share the same identifier with the macro base station. If the source access point AP changes, and the signal quality change of the reference signal corresponding to the source access point AP is greater than the threshold in the specified time window, the UE performs a recessive cell handover. The secondary cell handover can be regarded as a primary cell effective change, and the secondary cell handover needs to be included in the weighted value count. As shown in FIG. 6, the UE motion state estimation method may include the following steps:
