Description
Technical Field
The present invention relates to the field of mobile communication technologies, and in particular, to a method for measuring SNPL in a multi-carrier system, an RNC, and a multi-carrier terminal.
Background
The High Speed Uplink Packet Access (HSUPA) technology is an uplink enhancement scheme proposed by 3GPP release 7, in which a terminal carries neighboring cell and local cell path loss (SNPL) information measured by the terminal in uplink transmission, wherein the SNPL information can be carried by an enhanced random access uplink control channel (E-RUCCH) or by a Protocol Data Unit (PDU) of an enhanced physical uplink channel (E-PUCH).
In order to improve system capacity, 3GPP release 7 introduces the multi-frequency-point characteristic of a cell, that is, one cell may have multiple cell frequency points, one of the frequency points is a primary frequency point, the other frequency points are secondary frequency points, and the UE is in a single carrier operating mode, and the operating frequency point of the UE may be on the primary frequency point or the secondary frequency point of the cell. In a system having a multi-frequency-point characteristic, it is necessary to consider whether or not a neighboring cell includes a cell frequency point that is the same as a terminal operating frequency point for measurement of SNPL. As shown in fig. 1, it is assumed that cell frequency points of cell a are F1, F2, and F3, cell frequency points of cell B are F1, F4, and F5, cell frequency points of cell C are F3, F4, and F5, cell frequency points of cell D are F1, F3, and F5, the terminal is located in cell a, and its working frequency point is F3, because the cell frequency point of cell B does not include F3, the terminal will not interfere with it, therefore, the terminal only needs to consider the cell including F3 frequency point when measuring SNPL, and does not need to participate in measurement of SNPL for cell B that does not include F3.
In the existing specification, a Radio Network Controller (RNC) sends a common-frequency list and a different-frequency list to a terminal through a measurement control message, the common-frequency list includes neighboring cells having a same main frequency point and a same terminal working frequency point, the different-frequency list includes neighboring cells having a different main frequency point and a different terminal working frequency point, and 1-bit indication information is set for each neighboring cell in the different-frequency list, and the indication information is used for indicating whether a cell frequency point of the neighboring cell includes a working frequency point of the terminal. And each adjacent cell in the same-frequency list can participate in the measurement of the terminal on the SNPL, and only the adjacent cell indicating that the cell frequency point contains the terminal working frequency point in the different-frequency list can participate in the measurement of the terminal on the SNPL.
With the proposal of the multi-carrier technology, the terminal can work on a plurality of carriers simultaneously, namely, the terminal can have a plurality of working frequency points, and the technology can greatly improve the system throughput and is gradually emphasized. However, the SNPL measurement method provided in the prior art is only for the case of a single carrier technology, i.e. one working frequency point, and is not suitable for SNPL measurement in a multi-carrier technology.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention mainly comprises: the RNC at the network side indicates the inclusion condition of the cell frequency point of each adjacent cell of the cell where the multi-carrier terminal is located to each working frequency point of the multi-carrier terminal through a Radio Resource Control (RRC) dedicated control signaling or a system broadcast message; and the multi-carrier terminal determines the adjacent cells of the cell frequency point containing the working frequency point to respectively measure the SNPL of each working frequency point according to the received RRC dedicated control signaling or system broadcast message.
The following describes the above method in detail by taking two embodiments for two indication modes, namely, RRC dedicated control signaling or system broadcast message.
In the first embodiment, the RNC indicates, through the RRC dedicated control signaling, the inclusion status of the cell frequency point of each neighboring cell of the multi-carrier terminal to each working frequency point of the multi-carrier terminal. Fig. 2 is a flowchart of a method according to an embodiment of the present invention, and as shown in fig. 2, the method may include the following steps:
step 201: and the RNC indicates the inclusion condition of the cell frequency point of each adjacent cell to the working frequency point of the multi-carrier terminal for the multi-carrier terminal through the RRC special control signaling according to the working frequency point distributed to the multi-carrier terminal and the cell frequency point of each adjacent cell under the actual network layout condition.
The working frequency points allocated to the multi-carrier terminal and the cell frequency points of each neighboring cell are known in advance by the RNC, and the specific known manner is the prior art, which is not described herein again.
In this step, the inclusion status of the cell frequency point of each neighboring cell to each working frequency point of the multi-carrier terminal can be indicated by RRC dedicated control signaling in the following three ways:
the first mode is as follows: and the RNC configures a same-frequency list and an different-frequency list for each working frequency point of the multi-carrier terminal respectively, and sends the same-frequency list and the different-frequency list for each working frequency point to the multi-carrier terminal through a measurement control message.
When the RNC respectively configures a same-frequency list and a different-frequency list for each working frequency point, the same-frequency list comprises adjacent cells with the same frequency of the main frequency point and the working frequency point, and the different-frequency list comprises adjacent cells with different main frequency points and the working frequency point, wherein each adjacent cell in the different-frequency list comprises same-frequency indication information to indicate whether the cell frequency point of the adjacent cell comprises the working frequency point. For example, 1-bit common-frequency indication information may be set for each neighboring cell, and when the cell frequency point of the neighboring cell includes the working frequency point, the indication information is set to 1, otherwise, the indication information is set to 0. The same-frequency indication information can use 1-bit indication information in an inter-frequency list in the existing specification, so that the existing specification is compatible.
In specific configuration, in order to distinguish the common-frequency list and the different-frequency list of each working frequency point, a sequential mode or an indication mode can be adopted:
1) and (4) sequential expression. The RNC can configure a same-frequency list and a different-frequency list for each working frequency point of the multi-carrier terminal in sequence according to a preset sequence and send the same-frequency list and the different-frequency list to the multi-carrier terminal according to the configured sequence. Wherein, the preset sequence can be as follows: in order of carrier numbers, in order of carrier frequencies, etc.
2) And (4) indicating the formula. And the RNC sets same-frequency indication information in a same-frequency list or a different-frequency list aiming at each working frequency point, and indicates the corresponding working frequency point aiming at the same-frequency list and the different-frequency list. For example, 16 bits of same frequency indication information may be set, and the same frequency indication information may include the targeted operating frequency point information. This approach increases configuration flexibility over sequential approaches.
The second mode is as follows: the RNC configures a same-frequency list and a different-frequency list of the multi-carrier terminal according to a certain reference frequency point, indicates the inclusion condition of cell frequency points of each adjacent cell of a cell where the multi-carrier terminal is located to working frequency points of the multi-carrier terminal in the same-frequency list and the different-frequency list, and sends the same-frequency list and the different-frequency list to the multi-carrier terminal through a measurement control message.
The selection of the reference frequency point can be as follows: selecting any frequency point as a reference frequency point, or selecting a frequency point where a concomitant Dedicated Physical Channel (DPCH) is located as the reference frequency point, or selecting any one of the working frequency points of the multi-carrier terminal as the reference frequency point. At this time, the same-frequency list configured by the RNC includes neighboring cells with the same frequency of the main frequency point and the reference frequency point, and the different-frequency list includes neighboring cells with different frequencies of the main frequency point and the reference frequency point. In this way, the inclusion status of the working frequency point of the multi-carrier terminal needs to be indicated for each neighboring cell of the co-frequency list and the inter-frequency list, so the selection of the reference frequency point does not affect the implementation of the present invention.
The RNC may set M bits of common-frequency indication information for each neighboring cell in the common-frequency list and the different-frequency list, where M is an integer, and a value of M may be related to the number of carriers supported by the multi-carrier terminal. The value of the M-bit common-frequency indication information has a mapping relation with the inclusion status of each working frequency point of the multi-carrier terminal.
For example, the number of available carriers configured for the multi-carrier terminal by the network side is 2, that is, there are two working frequency points, M can be set to be 2, and 00 can be used to indicate that the cell frequency point of the neighboring cell does not contain either the first working frequency point or the second working frequency point of the multi-carrier terminal; adopting 01 to indicate that the cell frequency point of the adjacent cell only contains a second working frequency point of the multi-carrier terminal and does not contain a first working frequency point; adopting 10 to indicate that the cell frequency point of the adjacent cell only contains a first working frequency point of a multi-carrier terminal and does not contain a second working frequency point; and adopting 11 to indicate that the frequency point of the cell comprises both the first working frequency point and the second working frequency point of the multi-carrier terminal.
In this way, the original 1-bit indication information in the pilot frequency list may not be reserved; or, original 1-bit indication information in the pilot frequency list may be retained, if the cell frequency point of the neighboring cell at least includes one of the working frequency points of the multi-carrier terminal, the 1-bit indication information is set to 1, otherwise, the 1-bit indication information is set to 0.
Compared with the first mode, the second mode does not need to configure a same-frequency list and a different-frequency list for each working frequency point, and signaling resources are saved.
In this way, the M bits of co-frequency indication information in the co-frequency list may be as shown in table 1, and the M bits of co-frequency indication information in the inter-frequency list may be as shown in table 2. Table 1 is a common-frequency list in the second mode provided in the embodiment of the present invention, and table 2 is an inter-frequency list in the second mode provided in the embodiment of the present invention.
TABLE 1
TABLE 2
The third mode is as follows: the RNC adopts the additionally created RRC dedicated control signaling to indicate the conditions of the cell frequency points of all the adjacent cells of the cell where the multi-carrier terminal is located to the working frequency points of the multi-carrier terminal, and the newly created RRC dedicated control signaling can be sent to the multi-carrier terminal in the modes of RRC reconfiguration, measurement control and the like.
In this way, an RRC dedicated control signaling may be newly created outside the existing specification, and M bits of common-frequency indication information may also be set for each neighboring cell in the newly created RRC dedicated control signaling, where a value of M may be related to the number of carriers supported by the multi-carrier terminal. The value of the M-bit common-frequency indication information has a mapping relation with the inclusion status of each working frequency point of the multi-carrier terminal. The meaning of the M-bit same frequency indication information is the same as the second way.
The M-bit common-frequency indication information set for each neighboring cell may be arranged according to a preset order, for example, the M-bit common-frequency indication information may be arranged according to an appearance order in a common-frequency list or an inter-frequency list, so that the multi-carrier terminal can know to which neighboring cell the common-frequency indication information is directed, as shown in table 3, where the number of each neighboring cell may be arranged according to an arrangement manner of a common-frequency list and an inter-frequency list. Alternatively, the newly created RRC dedicated control signaling may include identification information of each neighboring cell, so that the multi-carrier terminal can know to which neighboring cell each co-frequency indication information is directed, as shown in table 4.
TABLE 3
TABLE 4
Step 202: the multi-carrier terminal respectively executes the following operations aiming at each working frequency point according to the indication in the received RRC dedicated control signaling: and determining the adjacent cells of the working frequency points contained in the cell frequency points, and calculating the SNPL of the working frequency points by using the cells and the broadcasting path loss of the determined adjacent cells.
When the RNC configures a same-frequency list and a different-frequency list in a first mode, after the multi-carrier terminal receives a measurement control message, all cells in the same-frequency list aiming at each working frequency are the cells considered in the SNPL calculation, and the same-frequency indication information in the different-frequency list indicates that the adjacent cells of which the frequency points contain the working frequency points are the cells considered in the SNPL calculation.
For the sequential mode, the multi-carrier terminal determines the adjacent cells in the same-frequency list and the adjacent cells with the same-frequency indication information of 1 in the different-frequency list according to a preset sequence for each working frequency point. For the indication mode, the multi-carrier terminal may first determine the working frequency point to which the corresponding common frequency list and different frequency list are directed according to the common frequency indication information set in the common frequency list or different frequency list, determine the neighboring cell in the common frequency list for the working frequency point, and determine the neighboring cell in the different frequency list for which the common frequency indication information is 1.
When the RNC adopts the second mode, after the multi-carrier terminal receives the measurement control message, according to the inclusion condition of the cell frequency points of all the adjacent cells indicated in the co-frequency list and the inter-frequency list to the working frequency points of the multi-carrier terminal, the adjacent cells of which the cell frequency points in the co-frequency list contain the working frequency points and the adjacent cells of which the cell frequency points in the inter-frequency list contain the working frequency points are determined aiming at all the working frequency points. Still taking the example in which M is 2 in the second manner as an example, for the first working frequency point, the multi-carrier terminal determines neighboring cells whose M bits of common-frequency indication information in the common-frequency list and the different-frequency list are 10 and 11, and for the second working frequency point, the multi-carrier terminal determines neighboring cells whose M bits of common-frequency indication information in the common-frequency list and the different-frequency list are 01 and 11.
When the RNC adopts the third mode, after the multi-carrier terminal receives the newly created RRC dedicated control signaling, the adjacent cells containing the working frequency points are determined aiming at the working frequency points according to the M-bit same frequency indication information of the adjacent cells.
The multi-carrier terminal can measure the broadcast path loss of the cell and the adjacent cell by reading the broadcast of the cell and the adjacent cell, and the multi-carrier terminal calculates the SNPL of each working frequency point by using the broadcast path loss of the cell and the determined broadcast path loss of the adjacent cell aiming at each working frequency point. The specific calculation method of SNPL is the prior art and is not described herein.
Step 203: and the multi-carrier terminal reports the SNPL of each working frequency point or the average SNPL of each working frequency point to a base station at a network side.
The multi-carrier terminal can report the SNPL of each working frequency point to the base station as the SNPL of the carrier level, and can also report the SNPL average value of each working frequency point to the base station as the SNPL of the user level.
As in the prior art, the multi-carrier terminal can report SNPL through E-RUCCH or MAC-E PDU of E-PUCH.
In the second embodiment, the RNC indicates the inclusion status of the cell frequency point of each neighboring cell to each working frequency point of the multi-carrier terminal through the system broadcast message. Fig. 3 is a flowchart of a method according to a second embodiment of the present invention, and as shown in fig. 3, the method may include the following steps:
step 301: and the RNC indicates the inclusion condition of the cell frequency points of each adjacent cell to the working frequency points of the multi-carrier terminal for the multi-carrier terminal through system broadcast messages according to the working frequency points distributed to the multi-carrier terminal and the cell frequency points of each adjacent cell under the actual network layout condition.
In this step, the inclusion status of the cell frequency point of each neighboring cell to the working frequency point of the multi-carrier terminal can be indicated by the system broadcast message in the following two ways:
the first mode is as follows: and the RNC configures a same frequency list and a different frequency list according to the main frequency point of the current cell, indicates the inclusion condition of the cell frequency points of each adjacent cell to the cell frequency points of the current cell in the same frequency list and the different frequency list, and broadcasts the same frequency list and the different frequency list to the multi-carrier terminal in the current cell through a system broadcast message.
Because the system broadcast message is broadcast and sent to all terminals in the cell, the RNC cannot specifically indicate a certain multi-carrier terminal, and because the working frequency points of the multi-carrier terminal are necessarily a subset of the cell frequency points of the cell in which the multi-carrier terminal is currently located, if the inclusion status of the cell frequency points of each neighboring cell and the cell frequency points of the current cell is indicated in the common frequency list and the different frequency list, the inclusion status of the cell frequency points of the neighboring cell and the working frequency points of the multi-carrier terminal is also indicated.
The same frequency indication information of Q bits can be set for each adjacent cell in a same frequency list and a different frequency list configured for the main frequency point of the current cell, and the value of Q can be related to the number of the cell frequency points of the cell. The value of the same-frequency indication information of the Q bit has a mapping relation with the inclusion condition of each cell frequency point of the current cell.
For example, assuming that the cell frequency points of the current cell are 3, that is, three working frequency points exist, Q may be set to 3, and 000 is adopted to indicate that the cell frequency points of the neighboring cell do not include any one of the cell frequency points of the current cell; using 001 to indicate that the cell frequency points of the adjacent cells only contain the third cell frequency point in the cell frequency points of the current cell; using 010 to indicate that the cell frequency points of the adjacent cell only contain the second cell frequency point in the cell frequency points of the current cell; adopting 011 to indicate that the cell frequency points of the adjacent cells only comprise the second and third cell frequency points in the cell frequency points of the current cell; and adopting 100 to indicate that the cell frequency points of the adjacent cells only comprise the first cell frequency point in the cell frequency points of the current cell, and the like. After receiving the system broadcast message, the multi-carrier terminal in the cell determines the neighboring cell containing the working frequency point for each working frequency point according to the working frequency point status of the multi-carrier terminal, for example, if the working frequency point of the multi-carrier terminal is a first cell frequency point and a second cell frequency point, the neighboring cell containing the first cell frequency point is determined for the first cell frequency point, and the neighboring cell containing the second cell frequency point is determined for the second cell frequency point.
In this situation, the intra-frequency list and the inter-frequency list of the intra-frequency indication information including the Q bit are similar to those shown in tables 1 and 2, and are not described herein again.
The second mode is as follows: and the additionally added information field in the system broadcast message indicates the inclusion condition of the cell frequency points of each adjacent cell to all the cell frequency points of the current cell.
The new information domain at least contains the same frequency indication information of W adjacent cells, wherein W is the number of the adjacent cells; each neighboring cell contains Q-bit co-frequency indication information, and the meaning of the Q-bit co-frequency indication information is the same as that of the first mode in the embodiment. The same frequency indication information in the new information domain may be numbered according to the appearance order in the same frequency list or the different frequency list, or the new information domain includes the identification information of each neighboring cell. The form of the new information field may also take the form of table 3 or table 4.
Step 302: the multi-carrier terminal respectively executes the following operations aiming at each working frequency point of the multi-carrier terminal according to the indication in the received system broadcast message: and determining the adjacent cells of the working frequency points contained in the cell frequency points, and calculating the SNPL of the working frequency points by using the cells and the broadcasting path loss of the determined adjacent cells.
When the RNC adopts the first mode to indicate, the multi-carrier terminal firstly determines which cell frequency points of the cell where the working frequency points of the multi-carrier terminal are corresponding to, and determines the adjacent cells of the working frequency points contained in the cell frequency points in the same frequency list and the different frequency list aiming at each working frequency point after receiving the same frequency list and the different frequency list in the system broadcast message.
When the RNC adopts the second mode to indicate, the multi-carrier terminal firstly determines which cell frequency points of the cell where the working frequency point of the multi-carrier terminal corresponds to, and determines the adjacent cell of the working frequency point in the cell frequency point indicated in the information domain aiming at each working frequency point after receiving a new information domain in the system broadcast message.
In this step, the multi-carrier terminal also calculates the SNPL of one carrier level for each working frequency point.
Step 303: and the multi-carrier terminal reports the SNPL of each working frequency point or the average SNPL of each working frequency point to a base station at a network side.
The multi-carrier terminal can report the SNPL of each working frequency point to the base station as the SNPL of the carrier level, and can also report the SNPL average value of each working frequency point to the base station as the SNPL of the user level.
As in the prior art, the multi-carrier terminal can report SNPL through E-RUCCH or MAC-E PDU of E-PUCH.
The above is a detailed description of the method provided by the present invention, and the following is a detailed description of the RNC and the multi-carrier terminal provided by the present invention.

Accordingly, the information transmitting unit 410 transmits a measurement control message or additionally created RRC dedicated control signaling.
In this case, the information indication unit 400 may specifically include: any one of the first information indication subunit 401, the second information indication subunit 402, the third information indication subunit 403, or the fourth information indication subunit 404.

The method comprises the steps that the value of M-bit same-frequency indication information and the inclusion condition of cell frequency points of an adjacent cell to each working frequency point of a multi-carrier terminal have a mapping relation; m is an integer related to the number of carriers supported by the multi-carrier terminal.
When the information indicating unit 400 indicates in a system broadcast message manner, it may configure an intra-frequency list and an inter-frequency list according to a main frequency point of a current cell, indicate, in the intra-frequency list and the inter-frequency list, inclusion conditions of cell frequency points of neighboring cells to cell frequency points of the current cell, and carry the intra-frequency list and the inter-frequency list in the system broadcast message; or, the information field additionally added in the system broadcast message indicates the inclusion status of the cell frequency point of each neighboring cell to each cell frequency point of the current cell.
Accordingly, the information transmitting unit 410 broadcasts a system broadcast message to the multi-carrier terminals in the current cell.
