Description
Technical field
The present invention relates to the communication technology, be specifically related to a kind of multicast single-frequency network transmission time configuration method and equipment.
Background technology
LTE (Long Term Evolution) system is a single-carrier system, and promptly each sub-district in the system has only a carrier wave to transmit.In the LTE-A system, for carrier aggregation technology has been introduced in the wireless transmission service that higher rate is provided.A plurality of carrier waves of different frequency can be used for simultaneously in the sub-district is user's service, and each carrier wave wherein is called a member carrier of carrier aggregation system.
MBSFN (multicast single-frequency network) is a kind of transmission means, promptly carries out synchronous transmission with same frequency in a plurality of sub-districts at one time.Use this transmission means can save frequency resource, improve the availability of frequency spectrum.It requires a plurality of sub-districts that identical content is sent simultaneously.So, the UE receiver just can be considered as a plurality of MBSFN sub-district a big sub-district.Therefore, UE not only can not be subjected to the presence of intercell interference of neighbor cell transmission, and will benefit from the stack from the signal of a plurality of MBSFN sub-district.In addition, if utilize advanced UE receiver technology can also solve the time difference problem of multipath transmisstion, disturb thereby eliminate in the sub-district.This multiple sectors at same keeps pouring in the defeated diversity that brings can also solve problems such as blind area covering, strengthens the reliability that receives, and improves coverage rate.
What the MBSFN transmission means related to is the synchronous transmission of a plurality of minizones, and the MBSFN transmission region is had following related definition:
(1) the MBSFN retaining zone is meant the zone of having the ability to carry out the MBSFN transmission, and all eNB this zone in can be by synchronously and carry out MBSFN and transmit.
(2) the MBSFN zone is meant by coordinating to have realized one group of sub-district of MBSFN transmission.For the UE that receives the MBSFN transmission, whole M BSFN zone can be counted as a MBSFN sub-district.
Can comprise a plurality of MBSFN zone in the MBSFN retaining zone, and the specific cell of MBSFN retaining zone also can belong to a plurality of different MBSFN zones.The MBSFN retaining zone generally realizes by configuration, and the MBSFN zone both can also can be realized by dynamic management by configuration.
Support among the LTE that the sub-district of MBFSN is the MBFSN dedicated cell or is MBFSN/ clean culture mixed cell.When a sub-district was configured to be exclusively used in the carrier frequency of MBSFN transmission, this sub-district was the MBFSN dedicated cell; Being configured to when a sub-district is not that this sub-district is a MBFSN/ clean culture mixed cell when being exclusively used in the carrier frequency of MBSFN transmission.Clean culture in the MBFSN/ clean culture mixed cell and MBSFN transmission are carried out with Peer, and some is used for the MBSFN transmission constantly, and other the moment is used for unicast transmission.
In the LTE system, for the transmission region that has disposed MBSFN, at given transmission time, system will utilize the whole transmission frequency bandwidth of institute's distributing carrier wave that all users that are arranged in this MBSFN transmission region are sent data.
Configuration to the MBSFN transmission time is the important content of MBSFN technology.The moment that is used for the MBSFN transmission in the sub-district that the LTE system supports MBSFN to transmit is notified the user by the system broadcasts of institute's distributing carrier wave.The configuration in the moment of MBSFN transmission can be cycle (each radio frames is 10 milliseconds, comprises 10 subframes in the radio frames, and each subframe is 1 millisecond) with 1 radio frames or 4 radio frames.Concrete which subframe is used for carrying out adopting the mode of bit mapping (bitmap) to indicate in the block of information that MBSFN is transmitted in system broadcast message in the radio frames.Because not all subframe can be configured to carry out the MBSFN transmission in the radio frames, so bitmap only needs to indicate and get final product disposing the subframe of carrying out the MBSFN transmission.In the LTE system, FDD (Frequency Division Duplexing (FDD)) pattern has 6 the configurable MBSFN of carrying out transmission of subframe, TDD (time division duplex) has 5 the configurable MBSFN of carrying out transmission of subframe, therefore, the length of bitmap was 6 bit when configuration cycle was 1 radio frames, the length of bitmap was 4*6=32 bit (owing to LTE system requirements FDD and TDD compatibility, so the length of bitmap all is unit with 6bit) when configuration cycle was 4 radio frames.
In adopting the LTE-A system of carrier aggregation technology, how to realize also not having corresponding solution before the configuration purpose of transmission time of MBSFN.
