Description

Information transmission method, base station, user equipment and communication system

technical field

The present invention relates to the communication field, in particular to an information transmission method, a base station, user equipment and a communication system.

Background technique

MBMS (English full name: Multimedia Broadcast Multicast Service, Chinese translation: broadcast service) is usually carried out according to the MBMS area (MBMS area). Several cells (usually adjacent cells) in the network form an MBMS area. The cells in the same MBMS area send the MBMS service (service) belonging to the MBMS area. For example, if an MBMS area provides CCTV1 TV programs, all cells within this MBMS area provide CCTV1 TV programs.

The base station (such as eNB) carries system information and other information together in MIB (full name in English: MasterInformation Block, Chinese translation:) message and SIB (full name in English: System Information Block, Chinese translation:) message through PBSH (full name in English It is: Physical Broadcast Channel, Chinese translation is: physical layer broadcast channel) and PDSCH (full name in English: Physical Downlink SharedChannel, Chinese translation is: ) sent to UE (full name in English: User equipment, Chinese translation is: user equipment), The UE parses the MIB message and SIB message to obtain system information, and continues to monitor the MCCH according to the relevant information (such as the location of the MCCH) recorded in the system information of the MCCH (English full name: MBMS Control Channel), and receives the MBMS service-related information transmitted by the MCCH, thereby realizing Receive MBMS services normally.

With the development of communication technology, some special carriers have appeared. There is no PBCH and PDSCH on these carriers, or the UE cannot determine the specific location of PBCH and PDSCH, so MIB messages and SIB messages cannot be transmitted on these carriers, resulting in the transmission system The information fails, affecting the UE to realize the broadcast service.

Therefore, how to transmit system information through other means to improve the success rate of system information transmission and ensure the realization of MBMS is a problem that needs to be solved at present.

When the base station transmits the system information to the UE through the designated time-frequency resource, transmit all of the system information to the UE through the designated time-frequency resource; or, transmit all of the system information to the UE through the designated time-frequency resource Part of the system information may be included in the first indication information, and the first indication information is used to notify the UE of the position of the time-frequency resource for transmitting the remaining part of the system information, that is, the second part, so that the UE can transmit the second part of the system information in the second The second system information is received on a part of the time-frequency resources, for example, the first indication information may indicate a subframe number for transmitting the remaining part of the system information. In this way, the UE can successfully receive all system information.

Optionally, the specified time-frequency resource is located in a unicast subframe, or the specified time-frequency resource is located in a broadcast subframe, or the specified time-frequency resource is located in a unicast subframe and a broadcast subframe.

Specifically, when the time-frequency resource for transmitting the system information is located in a unicast subframe, the UE performs demodulation using the corresponding CP length of the unicast subframe; when the time-frequency resource for transmitting the system information is located in a broadcast subframe, The UE uses a long CP for demodulation; when the time-frequency resource for transmitting the system information is located in a unicast subframe and a broadcast subframe, for the system information in the unicast subframe, the UE applies the corresponding CP length of the unicast subframe For demodulation, the UE applies the long CP to demodulate the system information of the broadcast subframe.

Optionally, the above system information is specific to the cell where the current UE is located; or, the above system information is specific to the MBMS area where the cell where the current UE is located.

Further, when the system information is specific to the cell where the current UE is located, when demodulating the system information, use the RS that is scrambled by using the cell identifier (such as a cell ID) where the current UE is located; or, when the The above system information is specific to the MBMS area where the cell where the current UE is located. When demodulating the system information, use the RS for scrambling with the MBMS area identifier (such as area ID) of the cell where the current UE is located.

The above information may only exist in some areas, or only some cells may have the above information.

Specifically, when the cell-id (cell identifier) of the cell where the UE is located is used for scrambling, the UE can obtain the cell-id during the PSS/SSS synchronization process, thereby obtaining the scrambling information of the RS, and realizing correct solution Call the system information.

When using the area id (area identifier) of the MBMS area where the cell where the UE is located is used for scrambling, the UE can obtain the area id in the following two ways:

Manner 1: Obtain at least one pre-configured MBMS area identifier.

The base station and the UE agree in advance that the area id is a fixed value, or a possible value of the area id. For example, it is pre-agreed that the area id is 0, and the UE can generate a DMRS according to the area id being 0, and then perform blind detection on the time-frequency resource to realize correct demodulation of the system information.

For example, it can be stipulated that the area id of at least one area in the MBMS service cell is 0, then the UE can generate a DMRS based on the area id being 0, and then perform blind detection on the time-frequency resource. If there is an MBMS service, the UE can demodulate out.

Way 2: Detecting a synchronization channel, where the synchronization channel carries at least one MBMS area identifier.

Pre-set the synchronization channel of the MBMS area where the cell where the UE is located, the base station uses the synchronization channel to send the area id to the UE, the UE obtains the area-id by detecting the synchronization channel, generates a DMRS, and then transmits the area-id on the time-frequency resource Receive and realize correct demodulation of the system information.

At least one cell included in the MBMS area where the cell where the UE is currently located, the MBMS area configured for each cell in the at least one cell, and the MCCH information of the MBMS area configured for each cell in the at least one cell.

For example, the MBMS area where the UE is located includes 4 cells, and the cell identifiers are Cell1, Cell2, Cell3, and Cell4 respectively, and the MCCH information of the MBMS area configured in each cell can be notified in the following manner: MBMS area configured in Cell1, Cell1 The id and MCCH information of each MBMS area configured; the MBMS area configured in Cell2, the id and MCCH information of each MBMS area configured in Cell2; the MBMS area configured in Cell3, the id and MCCH information configured in each Cell1 configured in Cell3; The MBMS area configured in Cell4, the id and MCCH information of each MBMS area configured in Cell4.

For another example, the MBMS area where the UE is located includes four cells, and the cell identifiers are Cell1, Cell2, Cell3, and Cell4 respectively, and the MCCH information of the MBMS area configured for each cell can be notified in the following manner: at least one of the four cells A cell is configured with MBMS area 1, the id of MBMS area 1, and MCCH information, and the cell configured with MBMS area 1 is Cell1; at least one of the four cells is configured with MBMS area 2, the id of MBMS area 2, and MCCH information. The cells in the MBMS area 2 are Cell2 and Cell3.
