Description

Method and equipment for receiving CSI-RS (channel State information-reference Signal) resources

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for receiving CSI-RS resources.

Background

CoMP (Coordinated Multipoint Transmission) technology refers to cooperation among multiple Transmission points separated in geographic locations, where the multiple Transmission points are base stations of different cells or multiple RRHs (Remote Radio heads, Radio remotes) controlled by a base station of the same cell; by means of cooperative transmission among a plurality of transmission points, interference among different transmission points can be effectively reduced, and the throughput of users (especially cell edge users) is improved. In addition, a set of transmission points directly or indirectly participating in cooperation of a UE (User Equipment) is referred to as a cooperation set, a set of transmission points where the UE needs to perform downlink Channel information measurement is referred to as a measurement set, and a set of transmission points directly participating in PDSCH (Physical downlink shared Channel) transmission of the UE is referred to as a transmission set.

The downlink CoMP technology comprises the following steps: CS/CB (cooperative scheduling/beamforming) and Joint processing (Joint processing); the CS avoids or reduces mutual interference through coordination of time, frequency and space resources among transmission points, and the performance of the UE at the edge of the cell can be improved through reducing the interference among the cells because the interference among the cells is a main factor for restricting the performance of the UE at the edge of the cell; the CB schedules the forming directions of a plurality of users in a cooperative cell to ensure that the beam directions of the users in different cells are mutually orthogonal, thereby reducing the mutual interference, and the CB is realized by the interference suppression processing of a sending end similar to the MU-MIMO (multi-user-multiple input multiple output) transmission of a single cell; in addition, in order to suppress interference caused by transmission of the user to transmission of other users, it is necessary to obtain downlink channel information of the cooperative cell at the base station side.

The joint processing scheme comprises dynamic transmission point switching and joint sending; in the dynamic transmission point switching, the base station can dynamically switch the transmission point for sending signals to the user, so that the optimal transmission point is selected each time for transmitting data; in order to implement dynamic transmission point switching, the base station needs to obtain channel information of multiple optional transmission points or obtain channel information of an optimal transmission point through a feedback channel. In the joint transmission scheme, a plurality of transmission points simultaneously transmit data to the UE to enhance the UE reception signal; and the superposition of useful signals from multiple transmission points can improve the quality of signals received by the UE; the scheme requires the UE to feed back the channel information of a plurality of transmission points, even the relative channel information among the transmission points, thereby ensuring that the plurality of transmission points can jointly carry out scheduling, precoding and data transmission; the transmission mode can be extended to a multi-user joint transmission (MU-JT) mode, where multiple transmission points simultaneously transmit data to multiple UEs on the same resource, and the multiple UEs ensure demodulation performance through orthogonal DMRSs (demodulation reference signals).

In Rel-10, in order to obtain downlink Channel state information, a CSI-RS (Channel state information Reference Signal) is introduced; the base station informs the UE of the resource configuration of the CSI-RS, and the UE performs CSI-RS detection on corresponding resources to obtain downlink CSI and feeds back the CSI to the base station; here, the CSI-RS is not transmitted in the special subframe, nor is it transmitted on resources that collide with synchronization signals, PBCH (Physical broadcast channel), SIB1 (System Information Block 1) Information, and the like.

In addition, the CSI-RS is not transmitted on a subframe for transmitting paging information, so as to prevent the CSI-RS from interfering with the UE's reception of the paging information; and because the UE knows the position (radio frame and corresponding subframe in the radio frame) of the paging information sent by the serving cell, the UE knows which resources do not need to detect the CSI-RS, and the UE cannot detect the CSI-RS even if CSI-RS transmission is configured on the corresponding subframe.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

in a CoMP scene, if CSI-RSs of multiple corresponding points indicated by a base station are from different cells, the corresponding CSI-RSs are sent by the different cells, paging information of the cells is sent independently, positions for sending the paging information are independent, and used paging parameters are also configured independently; because the UE can only know the position of the serving cell for sending the paging information and does not know the positions of other cells for sending the paging information, the CSI-RS is not detected only at the position of the serving cell for sending the paging information, and the CSI-RS is still detected at the positions of the other cells for sending the paging information, so that wrong CSI is obtained; if the paging information occupies more subframes, the accuracy of CSI measurement may be greatly reduced, and the downlink CoMP gain is affected.

Detailed Description

The inventor notices in the process of implementing the invention that: the UE may obtain the subframe in which the serving cell sends the paging information through the following two parameters: a paging DRX (Discontinuous Reception) period T and a paging density indication parameter nB; the paging DRX period T is the smaller value of a default DRX value common to the cells and a DRX value exclusive to the UE, and possible values are {32, 64, 128 and 256 }; nB is a density indication parameter common to the cells, and possible values are {4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }; based on the parameters T and nB, as shown in equation (1) and equation (2), the UE may calculate other paging resource related parameters:

n = min (T, nB) formula (1)

Ns = max (1, nB/T) equation (2)

Based on the parameters T, nB, N, and Ns, as shown in equations (3) and (4), the UE may calculate the radio frame and the radio subframe for transmitting paging information in one paging DRX cycle:

SFN mod T = (T div N) × (UE _ ID mod N) formula (3)

i _ s = floor (UE _ ID/N) mod Ns equation (4)

The SFN is a serial number of the wireless frame, and the wireless frame for sending paging information can be determined through the SFN; UE _ ID = IMSI mod 1024, that is, the UE _ ID is obtained from an IMSI (International Mobile Subscriber Identity) code of the UE, in FDD (Frequency Division Duplex) and TDD (time Division Duplex) systems, different Ns values correspond to different subframe indexes, and a radio subframe for transmitting paging information can be obtained from the subframe indexes; as shown in table 1 and table 2, Ns values of the FDD system and the TDD system are respectively used as a subframe index table, and a radio subframe for transmitting paging information can be determined according to the Ns value corresponding subframe index table.

Table 1 FDD Ns value corresponding subframe index table

Table 2: TDD Ns value corresponding subframe index table

Meanwhile, the inventor also notes that, as can be deduced from equations (1) and (3), the frame interval between radio frames that the serving cell may use to send paging information has a certain regularity, as shown in equation (5), where the frame interval is:

tp = max (1, T/nB) (unit is wireless frame) formula (5)

It should be noted that the value of this parameter is only related to nB, and not T.

In addition, for different cells, the radio frame numbers of the cells are not necessarily aligned, that is, the radio frame number of a cell corresponding to a measured CSI-RS resource of the UE may not be aligned with the radio frame number of the serving cell of the UE, and a certain radio frame offset k may exist between the radio frame numbers, and the UE can only transmit and receive according to the radio frame number of the serving cell.

In summary, the UE can obtain the position (i.e. the radio frame and the corresponding subframe in the radio frame) of the serving cell where the paging information is sent, so as to know on which resources the CSI-RS detection is not needed. However, in a CoMP scenario, because CSI-RSs are sent by different cells and the locations of the cells sending paging information are also independent, the UE can only know the location of the serving cell sending paging information and does not know the locations of other cells sending paging information, and therefore the UE can only detect no CSI-RS at the location of the serving cell sending paging information and can still detect CSI-RSs at the locations of other cells sending paging information, thereby obtaining an erroneous CSI; in addition, if the paging information occupies more subframes, the accuracy of CSI measurement may be greatly reduced, and the gain of downlink CoMP may be affected.

In view of the above problems, embodiments of the present invention provide a method and a device for receiving CSI-RS resources, where a UE obtains a radio frame and a radio subframe that may be used for sending paging information in a cell corresponding to a CSI-RS resource, and does not receive the CSI-RS resource on the radio frame and the radio subframe, so as to ensure that the UE can obtain correct CSI for downlink CoMP transmission, avoid obtaining incorrect CSI, ensure CoMP gain, and reduce complexity of the UE.

The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

The first embodiment of the invention provides a method for receiving a CSI-RS resource, wherein the CSI-RS resource can include but is not limited to a time-frequency configuration resource of a CSI-RS, a sequence configuration resource of the CSI-RS and the like; the method can be used for downlink transmission under any number of antennas, antenna arrays (such as linear arrays and polarized arrays), any duplex system (TDD system or FDD system) and any sending mode (such as SU-MIMO, MU-MIMO and CoMP); as shown in fig. 1, the method comprises the steps of:

step 101, a base station device determines paging resource information corresponding to a CSI-RS resource.

In the embodiment of the present invention, if the CSI-RS resource configured by the base station device for the UE is multiple CSI-RS resources, it is necessary to determine paging resource information corresponding to each CSI-RS resource, and a processing manner of each CSI-RS resource is processed according to the scheme provided in the embodiment of the present invention, and for convenience of description, the paging resource information corresponding to one CSI-RS resource is described later as an example.

In the embodiment of the present invention, the paging resource information includes but is not limited to one or any combination of the following parameters: discontinuous reception DRX cycle T; a packing density indication parameter nB; a paging subframe indication parameter Ns; paging radio frame offset k.

It should be noted that the paging resource information corresponding to the CSI-RS resource is the paging resource information corresponding to the CSI-RS resource, that is, the paging resource information of the sending cell of the CSI-RS resource; and the paging resource information of the serving cell of the UE is corresponding to the serving cell; since the sending cell of the CSI-RS resource and the serving cell of the UE may be different cells, the paging resource information corresponding to the CSI-RS resource and the paging resource information of the serving cell of the UE are configured independently, and the two may be configured as different parameter values without correlation.

In the embodiment of the present invention, the paging resource information corresponding to the CSI-RS resource includes, but is not limited to: paging resource information corresponding to the CSI-RS resources to be measured (namely, each CSI-RS resource to be measured); or, the paging resource information corresponding to each measured Cell, and different measured cells are embodied as different Cell IDs (Cell identifiers).

In the embodiment of the present invention, the determining, by the base station device, paging resource information corresponding to the CSI-RS resource specifically includes: the base station equipment determines paging resource information corresponding to the CSI-RS resource according to the scheduling result of the multiple cells; or the base station equipment determines paging resource information corresponding to the CSI-RS resource according to the result of the paging resource information interaction with other base stations; or, the base station device receives paging resource information configured by an Operation Administration and Maintenance (OAM) entity, and determines paging resource information corresponding to the CSI-RS resource by using configuration of the OAM entity; for example, the OAM entity may configure the paging resource information corresponding to the CSI-RS resource according to actual needs, and notify the base station device of the paging resource information, and the base station device determines the paging resource information corresponding to the CSI-RS resource based on the configuration.

Further, if the sending cell of the CSI-RS resource and the serving cell are co-sited, the base station equipment determines paging resource information corresponding to the CSI-RS resource according to the paging configuration parameters of the sending cell of the CSI-RS resource; if the sending cell and the serving cell of the CSI-RS resource are different sites, the base station device of the sending cell of the CSI-RS resource needs to interact with the base station device of the serving cell on the paging resource information (i.e., the paging configuration parameter thereof), and the base station device of the serving cell determines the interaction result as the paging resource information corresponding to the CSI-RS resource.

Step 102, the base station device sends paging resource information corresponding to the CSI-RS resource (i.e. paging resource information corresponding to the CSI-RS resource to be measured or paging resource information corresponding to each measured cell) to the UE.

In the embodiment of the invention, the base station equipment can indicate the paging resource information corresponding to the CSI-RS resource and the configuration information of the CSI-RS resource to each UE.

In the embodiment of the invention, the base station equipment can send the paging resource information corresponding to the CSI-RS resource to the UE through a high-level signaling.

It should be noted that if the paging resource information corresponding to a certain CSI-RS resource to be measured is the same as the paging resource information of the serving cell in which the UE is located, the base station device may not send the paging resource information corresponding to the CSI-RS resource to be measured to the UE; or, if the paging resource information corresponding to a certain measurement cell is the same as the paging resource information of the serving cell where the UE is located, the base station device may not send the paging resource information of the measurement cell to the UE.

In this embodiment of the present invention, when the paging resource information includes more than one parameter, the base station device may further perform joint coding on the more than one parameter, and send the paging resource information corresponding to the CSI-RS resource obtained by performing joint coding on the more than one parameter to the UE.

Step 103, the UE receives paging resource information corresponding to the CSI-RS resource from the base station equipment.

In the embodiment of the invention, when the base station equipment sends the paging resource information corresponding to the CSI-RS resource to the UE through the high-level signaling, the UE receives the paging resource information corresponding to the CSI-RS resource from the base station equipment through the high-level signaling.

In the embodiment of the present invention, for the sending process of the base station device, when the paging resource information includes more than one parameter, the UE may further receive the paging resource information corresponding to the CSI-RS resource notified by the base station device after performing joint coding on the more than one parameter.

And step 104, the UE utilizes paging resource information corresponding to the CSI-RS resource to obtain a radio frame and a radio subframe which are possibly used for sending the paging information.

In the embodiment of the present invention, the UE obtains a radio frame and a radio subframe which may be used for sending paging information by using paging resource information corresponding to CSI-RS resources, including: when the paging resource information corresponding to the CSI-RS resource is the paging resource information corresponding to the CSI-RS resource needing to be measured, the UE directly utilizes the paging resource information corresponding to the CSI-RS resource needing to be measured to obtain a radio frame and a radio subframe which are possibly used for sending the paging information in a cell corresponding to the CSI-RS resource; or, when the paging resource information corresponding to the CSI-RS resource is the paging resource information corresponding to each measured cell, the UE obtains a radio frame and a radio subframe which may be used for sending the paging information in the cell corresponding to the CSI-RS resource according to the cell ID corresponding to the CSI-RS resource and the paging resource information corresponding to the measured cell corresponding to the cell ID.

Further, the UE obtains a radio frame and a radio subframe that may be used for sending paging information by using paging resource information corresponding to the CSI-RS resource, and further includes: the UE obtains a radio frame and a radio subframe that may be used for sending the paging information according to the paging resource information corresponding to the CSI-RS resource and the paging resource allocation manner (i.e., the above formula 1-formula 5, and table 1 or table 2).

In this embodiment of the present invention, based on different paging resource information, the UE obtains a radio frame and a radio subframe that may be used for sending paging information according to the paging resource information corresponding to the CSI-RS resource and a paging resource allocation method, which include but are not limited to:

firstly, when the paging resource information is a subframe indication parameter Ns, the paging resource allocation mode is a subframe index table corresponding to the Ns value; and the specific obtaining mode is as follows:

the UE obtains all radio frames as radio frames that may be used for sending paging information (i.e., all radio frames may send paging information), and queries a subframe index table (i.e., table 1 or table 2) corresponding to the Ns value by using the subframe indicator parameter Ns, to obtain all subframe indexes corresponding to the subframe indicator parameter Ns as radio subframes that may be used for sending paging information.

And secondly, when the paging resource information is a paging density indication parameter nB, the paging resource allocation mode is as follows: n = min (T, nB), SFN mod T = (T div N) = (UE _ ID mod N), Ns = max (1, nB/T), Tp = max (1, T/nB), and Ns values correspond to the subframe index table; and the specific obtaining mode is as follows:

the UE obtains a radio frame possibly used for sending paging information by using a paging density indication parameter nB, values of all possible Ts, values of all possible UE _ IDs and formulas N = min (T, nB) and SFN mod T = (T div N) × (UE _ ID mod N), wherein the SFN is a radio frame serial number; or, the UE obtains a radio frame possibly used for sending paging information by using a paging density indication parameter nB, a value of a predetermined T, values of all possible UE _ IDs, and formulas N = min (T, nB) and SFN mod T = (T divN) (UE _ ID mod N), where SFN is a radio frame number; or, the UE obtains a radio frame possibly used for sending paging information by using the paging density indication parameter nB and the formula Tp = max (1, T/nB); and the UE obtains the subframe indication parameter Ns by using the paging density indication parameter nB and the formula Ns = max (1, nB/T), and queries a subframe index table (i.e., table 1 or table 2) corresponding to the Ns value by using the subframe indication parameter Ns to obtain all subframe indexes corresponding to the subframe indication parameter Ns as the radio subframes possibly used for sending paging information.

It should be noted that all possible values of T may be: possible values of the current paging DRX cycle T {32, 64, 128, 256 }; the value of the predetermined T may be a fixed value of T, or a value of T obtained by the UE from the serving cell.

And thirdly, when the paging resource information is DRX period T and paging density indication parameter nB, the paging resource allocation mode is as follows: n = min (T, nB), SFN mod T = (T div N) = (UE _ ID mod N), Ns = max (1, nB/T), and Ns values correspond to the subframe index table; and the specific obtaining mode is as follows:

the UE obtains a radio frame possibly used for sending paging information by using a paging density indication parameter nB, a DRX period T and values of all possible UE _ IDs, and formulas N = min (T, nB) and SFN mod T = (T div N) × (UE _ ID mod N), wherein the SFN is a radio frame serial number; and the UE obtains the subframe indication parameter Ns by using the paging density indication parameter nB and the formula Ns = max (1, nB/T), and queries a subframe index table (i.e., table 1 or table 2) corresponding to the Ns value by using the subframe indication parameter Ns to obtain all subframe indexes corresponding to the subframe indication parameter Ns as the radio subframes possibly used for sending paging information.

And fourthly, when the paging resource information is a paging density indication parameter nB and a paging radio frame offset k, the paging resource allocation mode is as follows: n = min (T, nB), SFN mod T = (T div N) = (UE _ ID mod N), Ns = max (1, nB/T), Tp = max (1, T/nB), and Ns values correspond to the subframe index table; and the specific obtaining mode is as follows:

the UE obtains radio frame sequence numbers of radio frames possibly used for sending paging information in corresponding cells by using a paging density indication parameter nB, values of all possible Ts and values of all possible UE _ IDs, and formulas N = min (T, nB) and SFN mod T = (T div N) × (UE _ ID mod N); acquiring the wireless frame sequence number of a wireless frame possibly used for sending paging information in a serving cell according to the paging wireless frame offset k; the SFN is a wireless frame sequence number; or, the UE obtains radio frame numbers of radio frames in corresponding cells, which may be used for sending paging information, by using the paging density indication parameter nB and the formula Tp = max (1, T/nB); acquiring the wireless frame sequence number of a wireless frame possibly used for sending paging information in a serving cell according to the paging wireless frame offset k; the SFN is a wireless frame sequence number; and the UE obtains the subframe indication parameter Ns by using the paging density indication parameter nB and the formula Ns = max (1, nB/T), and queries a subframe index table (i.e., table 1 or table 2) corresponding to the Ns value by using the subframe indication parameter Ns to obtain all subframe indexes corresponding to the subframe indication parameter Ns as the radio subframes possibly used for sending paging information.

And 105, the UE receives the CSI-RS resources on the obtained wireless frames and other wireless subframes except the wireless subframes, namely the UE does not receive and detect the CSI-RS resources on the obtained wireless frames and wireless subframes, so that the UE can obtain correct CSI for downlink CoMP transmission.

In the embodiment of the invention, if the UE does not receive paging resource information corresponding to the CSI-RS resource from the base station equipment, the UE can also obtain a radio frame and a radio subframe which are possibly used for sending the paging information by using the paging resource information of the serving cell, and receive the CSI-RS resource on other radio subframes except the obtained radio frame and radio subframe.

The following describes embodiments of the present invention in detail with reference to specific application scenarios.

Example two

An embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 2, where the method includes the following steps:

in step 201, the base station device indicates the UE 3 CSI-RS resources for measuring CSI, where the 3 CSI-RS resources are sent by the same base station device but belong to different cells.

Step 202, the base station equipment respectively indicates the paging resource information corresponding to each CSI-RS resource by using 2 bits, the paging resource information is a subframe indication parameter Ns, and the paging resource information is obtained by the paging resource configuration of the corresponding CSI-RS resource sending cell; the content of the indication bit (2 bits) is shown in table 3.

TABLE 3

In step 203, after receiving the information of the CSI-RS resource and the corresponding paging resource information (Ns), for each CSI-RS resource, the UE finds a radio frame and a radio subframe that may be used by the cell where the UE is located in table 1 or table 2 according to Ns.

For example, if Ns =2 corresponding to a certain CSI-RS resource, from table 1 or table 2, in an FDD system, the paging subframe index that may be used by its cell is {4, 9 }; in the TDD system, the paging subframe index that may be used by the cell is {0, 5 }; further, the UE assumes that the base station device may send paging information on a paging subframe of each radio frame, so as to determine a radio frame and a radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

And step 204, the UE does not receive and estimate corresponding CSI-RS resources on the resources according to the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

For example, in the FDD system, according to the calculation result of step 203, the UE will not receive the CSI-RS resource corresponding to the paging resource on subframe 4 and subframe 9 of each radio frame.

EXAMPLE III

An embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 3, where the method includes the following steps:

step 301, the base station device indicates the UE that 3 CSI-RS resources are used for measuring CSI, the 3 CSI-RS resources belong to 3 different base stations/cells, respectively, and the base station device obtains the paging resource configuration nB of the transmitting cell of the 3 CSI-RS resources through interaction with other base stations.

Step 302, the base station device respectively indicates paging resource information corresponding to each CSI-RS resource by using 3 bits, where the paging resource information is a paging density indication parameter nB, and the 3 bits are used to indicate 8 possible nB values: {4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }.

In step 303, after receiving the information of the CSI-RS resource and the corresponding paging resource information (nB), the UE obtains, for each CSI-RS resource, a radio frame set in which the corresponding cell may send paging information according to formula 1 and formula 3, according to the corresponding nB, the value of T agreed by the base station device and the UE, and the values of all possible UE _ IDs.

Note that the value of T agreed by the base station device and the UE may be the smallest value among possible values of T, or may be a value of T acquired by the UE from the serving cell where the UE is located, and after all possible values of the UE _ ID are substituted into formula 3, the possible value of the UE _ ID mod N may be obtained as 0.

Specifically, if a minimum value of T is 32 for a certain CSI-RS resource convention, nB = T/8=4, N =4 can be obtained according to formula 1, and a set of radio frame numbers that may send paging information in a corresponding cell in a paging cycle (T =32 radio frames) can be obtained according to formula 3 as follows: SFN mod T = (T div N) × (UE _ ID mod N) =8 × {0,1, 2, 3} = {0, 8, 16, 24 }; therefore, the UE may send paging information of the cell corresponding to the CSI-RS resource on all radio frames with the radio frame number being an integer multiple of 8.

And step 304, the UE obtains the value of Ns according to nB corresponding to each CSI-RS resource and a formula 2, and obtains the radio subframes possibly used by paging information of the cell corresponding to each CSI-RS resource in a table 1 or a table 2 according to Ns.

For example, if nB = T/8 corresponding to a certain CSI-RS resource, Ns =1 may be obtained based on equation (2); from table 1 or table 2, in the FDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {9 }; in the TDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {0 }.

And 305, the UE does not receive and estimate corresponding CSI-RS resources on the resources according to the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

For example, in the TDD system, according to the calculation results in step 303 and step 304, the UE does not receive the CSI-RS resource corresponding to the paging resource in subframe 0 on the radio frame with the radio frame number being an integer multiple of 8.

Example four

An embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 4, where the method includes the following steps:

step 401, the base station device indicates the UE that 3 CSI-RS resources are used for measuring CSI, the 3 CSI-RS resources belong to 3 different base stations/cells, respectively, and the base station device obtains the paging resource configuration nB of the transmitting cell of the 3 CSI-RS resources and the radio frame offset k between the transmitting cell of the 3 CSI-RS resources and the serving cell of the UE through interaction with other base stations.

Step 402, the base station device respectively uses 3 bits to indicate paging resource information (i.e. paging density indication parameter nB) corresponding to each CSI-RS resource, and respectively uses 5 bits to indicate a radio frame offset k between a cell corresponding to each CSI-RS resource and a serving cell of the UE, and the 3 bits are used to indicate 8 possible nB values: {4T, 2T, T, T/2, T/4, T/8, T/16, T/32}, and the 5 bits indicate 32 possible radio frame offset values k of {0, 1.. 31}, respectively.

In step 403, after receiving the information of the CSI-RS resource and the corresponding paging resource information (nB), for each CSI-RS resource, a set of radio frame numbers that may send the paging information in the cell corresponding to the CSI-RS resource is obtained by formula 5 according to the corresponding nB.

Specifically, assuming nB = T/4, Tp =4 can be obtained according to equation 5, that is, the frame interval between radio frames that may be used for sending paging information is 4, so as to obtain a radio frame with a set of radio frame sequence numbers {0, 4, 8. } that is, all radio frames with sequence numbers that are multiples of 4, in a cell corresponding to the CSI-RS resource and that may be used for sending paging information.

In step 404, after receiving the radio frame offset k between the cell corresponding to each CSI-RS resource and the serving cell of the UE, for each CSI-RS resource, according to the radio frame offset k and the set of radio frame numbers that may send paging information in the cell corresponding to the CSI-RS resource, a set of radio frame numbers in the serving cell of the UE of the set of radio frame numbers that may be used for sending paging information is obtained.

Specifically, if the set of radio frames possibly used for transmitting paging information in the CSI-RS resource corresponding cell is all radio frames with sequence numbers being multiples of 4, and the radio frame offset k =2, the set of radio frame sequence numbers possibly used for transmitting paging information in the serving cell of the UE is {2, 6, 10, 14, … }, that is, all radio frames with sequence numbers being 4m +2, and m is a non-negative integer.

Step 405, the UE obtains a value of Ns according to nB corresponding to each CSI-RS resource and formula 2, and obtains a radio subframe that may be used by paging information of a cell corresponding to each CSI-RS resource in table 1 or table 2 according to Ns.

For example, if nB = T/4 corresponding to a certain CSI-RS resource, Ns =1 may be obtained based on equation (2); from table 1 or table 2, in the FDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {9 }; in the TDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {0 }.

In step 406, the UE does not receive and estimate the corresponding CSI-RS resources on the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

For example, in the TDD system, according to the calculation results in step 404 and step 405, the UE does not receive the CSI-RS resource corresponding to the paging resource in the subframe 0 of the radio frame with the radio frame number 4m +2 (m is a non-negative integer).

EXAMPLE five

An embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 5, where the method includes the following steps:

step 501, a base station device indicates 3 CSI-RS resources of a UE for measuring CSI, where the 3 CSI-RS resources belong to 3 different base stations/cells, respectively, and the base station device obtains paging resource configuration of a sending cell of the 3 CSI-RS resources through interaction with other base stations.

Step 502, the base station device respectively indicates paging resource information corresponding to each CSI-RS resource by using 3 bits, where the paging resource information is a paging density indication parameter nB, and the 3 bits are used to indicate 8 possible nB values: {4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }.

In step 503, after receiving the information of the CSI-RS resource and the corresponding paging resource information (nB), for each CSI-RS resource, a set of radio frames that may send the paging information in the corresponding cell is obtained according to formula 1 and formula 3 according to the corresponding nB.

It should be noted that, as shown in formula 1 and formula 3, when nB > = T, the cell may transmit paging information on all radio frames; when nB < T, the cell may send paging information on all radio frames with radio frame number integer multiple of T/nB.

Specifically, if nB =2T corresponding to a certain CSI-RS resource, a cell corresponding to the CSI-RS resource may send paging information on all radio frames; if nB = T/8 corresponding to a certain CSI-RS resource, the cell corresponding to the CSI-RS resource may send paging information on all radio frames with radio frame numbers that are integer multiples of 8.

In step 504, the UE obtains a value of Ns according to nB corresponding to each CSI-RS resource and formula 2, and obtains a radio subframe that may be used by paging information of a cell corresponding to each CSI-RS resource in table 1 or table 2 according to Ns.

And 505, the UE does not receive and estimate the corresponding CSI-RS resources on the resources according to the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

EXAMPLE six

An embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 6, where the method includes the following steps:

step 601, the base station equipment indicates 2 CSI-RS resources of the UE for measuring CSI, the 2 CSI-RS resources belong to 2 different base stations/cells respectively, and the base station equipment obtains paging resource configuration of sending cells of the 2 CSI-RS resources through interaction with other base stations.

Step 602, the base station device indicates paging resource information corresponding to each CSI-RS resource with 5 bits, where the paging resource information is nB and T; where 3 bits are used to indicate 8 possible nB values: {4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }; 2 bits are used to indicate the 4 possible values of T32, 64, 128, 256.

Step 603, after receiving the information of the CSI-RS resource and the corresponding paging resource information (nB and T), the UE obtains, according to the values of nB and T and the values of all possible UE _ IDs, a set of radio frames that may send paging information in the corresponding cell according to formulas 1 and 3 for each CSI-RS resource.

Note that substituting all possible values of UE _ ID into equation 3 may result in a possible value of UE _ ID mod N being 0.

Specifically, if T =64 and nB =2T are given for a certain CSI-RS resource, N = T may be obtained according to formula 1, and a set of radio frame numbers that may send paging information in a corresponding cell in a paging cycle (T =64 radio frames) may be obtained according to formula 3 as follows: SFN mod T = (T div N) × (UE _ ID mod N) =1 × {0, 1.. T-1} = {0, 1.., 63 }; therefore, the UE considers that the paging information of the cell corresponding to the CSI-RS resource may be sent on all radio frames.

Step 604, the UE obtains the value of Ns according to nB corresponding to each CSI-RS resource and formula 2, and obtains a radio subframe that may be used by paging information of a cell corresponding to each CSI-RS resource in table 1 or table 2 according to Ns.

For example, if nB =2T corresponding to a certain CSI-RS resource, Ns =2 may be obtained based on equation (2); from table 1 or table 2, in the FDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {4, 9 }; in the TDD system, the paging subframe index that may be used by the paging information of the cell corresponding to the CSI-RS resource is {0, 5 }.

Step 605, the UE does not receive and estimate the corresponding CSI-RS resources on the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

For example, in the TDD system, according to the calculation results of steps 603 and 604, the UE will not perform reception of the CSI-RS resource corresponding to the paging resource on subframes 0 and 5 of each radio frame.

EXAMPLE seven

The seventh embodiment of the present invention provides a method for receiving CSI-RS resources, as shown in fig. 7, the method includes the following steps:

in step 701, the base station equipment indicates 2 CSI-RS resources of the UE for measuring CSI, where the 2 CSI-RS resources belong to different cells of the same base station, respectively, and the CSI-RS resource indication information includes information of a cell ID corresponding to the CSI-RS resource indication information.

Step 702, the base station device respectively indicates the paging resource information corresponding to each measured cell ID by using 3 bits, where the paging resource information is nB, and the 3 bits are used to indicate 8 possible nB values: {4T, 2T, T, T/2, T/4, T/8, T/16, T/32 }.

In step 703, after receiving the information of the CSI-RS resource and the paging resource information (nB) corresponding to each measured cell ID, the UE finds the paging resource information nB corresponding to the cell ID according to the information of the cell ID corresponding to each CSI-RS resource included in the indication information of the CSI-RS resource.

Step 704, for each CSI-RS resource, the UE obtains, according to the corresponding nB, the value of T agreed by the base station device and the UE, and the values of all possible UE _ IDs, a set of radio frames in which the corresponding cell may send paging information according to formulas 1 and 3.

Step 705, the UE obtains a value of Ns according to nB corresponding to each CSI-RS resource and formula 2, and obtains a radio subframe that may be used by paging information of a cell corresponding to each CSI-RS resource in table 1 or table 2 according to Ns.

In step 706, the UE does not receive and estimate the corresponding CSI-RS resources on the radio frame and the radio subframe occupied by the paging information of the cell corresponding to each CSI-RS resource.

In summary, according to the embodiments of the present invention, only a small amount of paging resource information needs to be notified by the base station device, and the UE can more accurately infer paging radio frames and subframe resources that may be used by the base station device by using the paging resource information and the paging resource allocation manner, so that the UE knows the paging resources used by the sending cells of each CSI-RS resource, thereby avoiding obtaining wrong CSI and ensuring CoMP gain; also, by avoiding unnecessary CSI-RS detection, the complexity of the UE can be reduced.
