Description

MCCH and MCCH update indication information control information carrying and receiving method and device

The present invention relates to a bearer and receive technology for control information of a multimedia broadcast multicast service control channel (MCCH, MBMS Control Channel) and MCCH update indication information, and more particularly to a multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service). MCCH and MCCH update method and device for carrying and receiving control information of indication information. Background technique

With the rapid development of the Internet and the popularity of large-screen multi-function mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services, such as video conferencing, television broadcasting, video on demand, advertising, online education, interactive games, etc., have emerged. This aspect meets the needs of mobile users for multiple services, and also brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity.

In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP) proposes MBMS, which is a technology for transmitting data from one data source to multiple target mobile terminals, realizing the network ( The sharing of resources including the core network and the access network improves the utilization of network resources (especially air interface resources). MBMS defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service broadcast and multicast, providing a variety of rich video, audio and multimedia services, which undoubtedly conforms to future mobile The trend of data development provides a better business prospect for the development of 3G. In the Long Term Evolution (LTE) system, the bearer mode of the MBMS control channel MCCH is still inconclusive. According to the agreement in the protocol 36.300-870, the MCCH can be transmitted in a single cell mode and mapped to the downlink shared channel (DL). -SCH, Downlink The shared channel is combined with the neighboring cell without multimedia broadcast multicast service (MBSFN, Multimedia Broadcast Multicast Service Single Frequency Network), and can also be transmitted in multi-cell mode and mapped to the multicast channel (MCH, Multicast Channel). The upper transmission, and the neighboring cell perform MBSFN merging. The DL-SCH and the MCH are finally mapped to the subframe of the physical layer. When the network side carries the MCCH in a certain subframe, the control information of how to carry the MCCH in the subframe data domain needs to be notified in the subframe. The control domain is sent to the mobile terminal. In the LTE system, the radio network temporary identifier (RNTI) passing through the MCCH in the control domain (corresponding to the Physical Downlink Control Channel (PDCCH)) of the subframe carrying the MCCH may be used in the LTE system. The Radio Network Temporary Identifier identifies the MCCH control information in the control domain, so that the mobile terminal acquires the MCCH control information from the control domain, and then receives the MCCH in the data domain according to the indication of the MCCH control information.

Currently, the manner in which the MCCH update indication information is sent in LTE has not been determined yet, but the manner in which the MCCH update indication information control information is acquired at the subframe level is likely to be the same as the manner in which the MCCH control information is obtained.

The basic idea of the present invention is: MCCH and MCCH update indication information use the same or different RNTI, and the RNTI helps the mobile terminal to find control information of the MCCH or MCCH update indication information in the control domain of the subframe (bearing by the PDCCH), the control The information describes the location of the MCCH or MCCH update indication information in the data field (beared by the DL-SCH) of the subframe, and the modulation coding mode (MCS, Modulation and Coding Scheme) information used. The control information includes scheduling bearer information of MCCH and MCCH update indication information.

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings.

1 is a flowchart of Embodiment 1 of a method for carrying control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 1, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:

Step 101: Set the same RNTI for the MCCH and MCCH update indication information.

The RNTI is a parameter configured by the network side. When the RNTI of the MCCH has been configured, the MCCH is updated to reduce the complexity of the system configuration and reduce the processing complexity when the mobile terminal receives the control information of the MCCH and the MCCH update indication information. The RNTI of the indication information is configured to be the same as the RNTI of the MCCH, so that one RNTI can be configured in the system to implement the MCCH. The control information and the reception of the control information of the MCCH update indication information.

The RNTI is an identifier that assists the mobile terminal in receiving control information of the MCCH and the MCCH update indication information in the control domain of the subframe. When the network side of the MBMS system encapsulates the control information of the MCCH and the MCCH update indication information, the RNTI is implicitly included in the MCCH. And the CRC (Cyclic Redundancy Check) check code of the MCCH update indication information (refer to the LTE protocols 36.212 and 36.211 protocols), where the MCCH or MCCH update indication information control information respectively describes the MCCH and MCCH update indications. The information is in the data field of the subframe (corresponding to the DL-SCH), the MCS information used, and the like. The control information of the MCCH includes scheduling configuration information, which is used to describe the time-frequency resource information of the MCCH in the subframe data domain, the MCS information used by the MCCH, and the like. The control information of the MCCH update indication information includes scheduling configuration information, which is used to describe the time-frequency resource information of the MCCH update indication information in the subframe data domain, and the adopted MCS information and the like.

Step 102: Carry one of the control information of the MCCH and MCCH update indication information that includes the RNTI in a non-public search area of a subframe control domain, and another control information is carried in a common search area of a subframe control domain.

In LTE, the first to four Orthogonal Frequency Division Multiplexing (OFDM) symbols of one subframe are the control i or the subframe. Which OFDM symbols are controlled by i or specifically, are determined and notified by the system network side. The unit for carrying control information in the subframe control domain is a Control Channel Element (CCE).

The control information of the MCCH and the MCCH update indication information is carried in the non-public search area and the common search area in the subframe control domain, that is, the MCCH and the MCCH update indication are distinguished by the time-frequency resources of the control information carrying the MCCH and the MCCH update indication information. The control information of the information, so that the mobile terminal receives the control information of the MCCH and the MCCH update indication information on the corresponding time-frequency resource. Since the control information of the MCCH update indication information is that the mobile terminal needs to receive and read from time to time, it can be carried in the public search area of the control domain, due to the public search area. The CCE resource range used is fixed and relatively small, which can improve the efficiency of blind detection of the mobile terminal, and is beneficial to the power saving of the mobile terminal. The MCCH control information is carried in a non-public search area. Similarly, the control information of the MCCH is carried in the common search area, and the control information of the MCCH update indication information is carried in the non-public search area.

The format of the downlink control information (DCI, Downlink Control Information) used by the MCCH and MCCH update indication information is the same. In the LTE system, the DCI format of the control information is set, and one of them is selected and notified to the mobile terminal. Of course, different DCI formats may be selected for the control information of the MCCH and MCCH update indication information.

The network side transmits the control information of the RNTI containing the MCCH in the control domain of the subframe in which the MCCH is transmitted, and sends the MCCH on the time-frequency resource of the data field indicated by the control information. The network side sends the control information of the RNTI containing the MCCH update indication information to the control domain bearer of the subframe in which the MCCH update indication information is sent, and sends the MCCH update indication information on the time-frequency resource of the data domain indicated by the control information. .

2 is a flowchart of Embodiment 2 of a method for carrying control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 2, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:

Step 201: Set the same RNTI for the MCCH and MCCH update indication information.

The implementation of this step is the same as that of step 101, and details are not described herein again.

Step 202: Carry one of the control information including the MCCH and MCCH update indication information of the RNTI in a CCE within an agreed range; or control information including the MCCH and MCCH update indication information of the RNTI They are carried in CCEs within different agreed scopes.

That is, at least one of the control information of the MCCH or the MCCH update indication information is set to a dedicated CCE, such that the control information of the MCCH or the MCCH update indication information carried in the dedicated CCE is carried in the CCE other than the dedicated CCE. That is MCCH update indication information Or MCCH control information.

A dedicated CCE can also be set for the control information of the MCCH and the control information of the MCCH update indication information. The mobile terminal can determine which CCEs carry the MCCH control information and which CCEs are carried by the CCE number in the subframe control domain. It is the control information of the MCCH update indication information. By carrying a dedicated CCE, the number of blind detections of the terminal can be greatly shortened, thereby realizing power saving of the terminal, and realizing the terminal to quickly receive corresponding control information. When the control information of the MCCH and the control information of the MCCH update indication information are carried in the same subframe, the number of the CCEs carrying the control information of the MCCH and the MCCH update indication information is preferably consecutive, and the numbers in the subframe are 17 to 24. The CCE carries the control information of the MCCH update indication information, and the CCEs numbered 25 to 32 carry the MCCH control information, so that the mobile terminal can only know the corresponding control information by blindly checking the CCEs numbered 17 to 32.

In this example, the DCI formats used by the MCCH and MCCH update indication information are the same or different. The preferred DCI format is format 1C (specific format definition refers to LTE protocol 36.212).

The control information of the MCCH and the MCCH update indication information in the step 202 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).

3 is a flowchart of Embodiment 3 of a method for loading control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 3, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of the present example is shown in FIG. Includes the following steps:

Step 301: Set the same RNTI for the MCCH and MCCH update indication information.

Step 302: The control information of the MCCH and MCCH update indication information including the RNTI is respectively carried in a control domain of a subframe, and the control information of the MCCH and MCCH update indication information uses different DCI formats. In this step, the DCI format selected for the control information of the MCCH and the MCCH update indication information is differentiated. Here, the DCI format of the MCCH and the MCCH update indication information may also be used, and the DCI is preferably used by the MCCH. The format is the format 1C format, the MCCH update indication information may use other DCI formats for downlink, or the DCCH format is format 1C format for the MCCH update indication information, and the other DCI format for the downlink may be used for the MCCH information. . The mobile terminal performs blind detection according to different DCI formats, and can respectively receive control information of the MCCH and MCCH update indication information. For the implementation of blind detection, refer to the relevant description in Protocol 36.212.

In order to enable the mobile terminal to receive the control information of the MCCH and the MCCH update indication information more quickly, if the DCI format selected by the MCCH and the MCCH update indication information is different, the control information of the MCCH and the MCCH update indication information may be The bearer is carried in the bearer mode in the foregoing step 102 and step 202.

The control information of the MCCH and the MCCH update indication information in the step 302 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).

As shown in FIG. 4, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:

Step 401: Set the same RNTI for the MCCH and MCCH update indication information.

Step 402: The control information of the MCCH and MCCH update indication information including the RNTI is respectively carried in a control domain of different subframes.

This example is distinguished by the subframe number of the control information carrying the MCCH and MCCH update indication information, and the subframe of the control information carrying the MCCH and MCCH update indication information And MCCH update indication information control information. For example, the MCCH is transmitted on the subframe #2 of the radio frame #32, and the MCCH update indication information is transmitted on the subframe #1 of the radio frame #32, and the respective control information is carried in the subframe #2 of the radio frame #32, respectively. On subframe #1, the control information of the MCCH and MCCH update indication information that is detected can be determined by the subframe number. At this time, the DCI format used for the control information of the MCCH and MCCH update indication information is preferably the same.

The control information of the MCCH and the MCCH update indication information in the step 402 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).

To control the MCCH and MCCH update indication information, the RNTI of the MCCH update indication information is set to be different from the RNTI of the MCCH. The division of the control information of the MCCH and MCCH update indication information can be realized by the RNTI.

Step 502: The control information of the MCCH and MCCH update indication information including the RNTI is carried in a control domain of the subframe.

Since the control information of the MCCH and the MCCH update indication information can be distinguished by the RNTI, the control information of the MCCH and the MCCH update indication information is carried in any position in the subframe control domain regardless of the control information of the MCCH and the MCCH update indication information. Whether the DCI format used is the same, the mobile terminal can always detect the control information that distinguishes the MCCH and MCCH update indication information. In order to make the control information of the mobile detection MCCH and the MCCH update indication information more efficient, the bearer mode shown in the foregoing FIG. 1 to FIG. 4 may be adopted, and is not described here again.

Step 602: The control information of the MCCH that includes the RNTI is carried in a non-public search area or a common search area of a subframe control domain. Alternatively, the control information of the MCCH that includes the RNTI is carried in an agreed range. Alternatively, the control information of the MCCH including the RNTI uses the agreed downlink control information DCI format.

For the implementation of step 602, refer to the bearer modes of steps 102, 202, and 302.

FIG. 7 is a flowchart of a method for carrying control information of MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 7, the method for carrying control information of MCCH update indication information in an MBMS system in the MBMS system of the present invention includes the following steps:

Step 701: Set the RNTI for the MCCH update indication information. The setting manner is similar to the setting method in the foregoing step 101, and details are not described herein again.

Step 702: The control information of the MCCH update indication information that includes the RNTI is carried in a non-public search area or a common search area of a subframe control domain. Alternatively, the MCCH update indication information including the RNTI is controlled. The information is carried in the CCE within the agreed range; or the control information including the MCCH update indication information of the RNTI is used in the agreed downlink control information DCI format.

For the implementation of step 702, refer to the bearer modes of steps 102, 202, and 302.

The MCCH control information and the MCCH update indication information share the same fixed downlink control signaling format, such as the format 1C format of the DCI, to send the MCCH control information and the MCCH update indication information to the UE, and use the agreed-upon in the DCI format 1C. RNTI (The main purpose of the DCI format here is to limit the DCI format of the UE to be blindly detected, because there may be multiple different DCI formats, and different DCI formats are mainly distinguished by the number of bits; the agreed RNTI is Used to identify this DCI format 1C is the UE needs to receive). Here, DCI format 1C is an existing DCI format. The following embodiment utilizes the DCI format, but the bit meaning in the existing DCI format has changed, and only the total number of bits in the DCI format has not changed. The specific implementation is as follows:

When the MCCH control information and the MCCH update indication information are not in the same subframe, the DCI format 1C is directly used to transmit the MCCH control information to the UE on the PDCCH of the subframe in which the MCCH control information appears, and the DCI format is simultaneously 1C uses the agreed RNTI, and the information in the format 1C includes at least the resource allocation information indicating the MCCH information on the PDSCH; and the MCCH update indication is directly used by using the DCI format 1C on the physical downlink control channel of the subframe in which the MCCH update indication information appears. The information is sent to the UE, and the agreed RNTI is used for the format 1C, that is, the bit information in the DCI format 1C is used to indicate the MCCH update indication information.

When the MCCH control information and the MCCH update indication information appear in the same subframe, the DCI format 1C uses the bits in the PDCCH of the subframe to simultaneously indicate the MCCH control information and the MCCH update indication information, and a specific use is given here. A method for indicating information of different meanings in different bits in the same DCI: using the first N bits of the DCI format 1C format to respectively represent N MCCH update indication information in a bitmap manner, where the value of N is the maximum supported by a cell in the system. The number of MCCHs, for example, a cell in LTE supports a maximum of 8 MCCHs, then the above N=8; the remaining bits in the DCI format 1C are used to represent the MCCH control information, which is used to describe the resource location of the MCCH information in the PDSCH. information. The foregoing method may also be applied to the case where the MCCH control information and the MCCH update indication information appear in different subframes, that is, the MCCH control information and the MCCH update indication information are configured in different subframes, and the MCCH control information is used by the DCI format 1C. The bit representation after the Nth bit (for example, N=8), the first N bits are reserved, and does not indicate any meaning; the MCCH update indication information is represented by the first N bits, and the following bits do not indicate any meaning. In this way, the different meanings of the bits in different DCI formats can be used to represent the MCCH control information and the MCCH update indication information, which avoids the increase of the DCI format and reduces the trouble of standardization.
