Embodiment 1

[0139] The scenario of this embodiment is that the SC-MCCH includes counting request information; such as Image 6 As shown, the process includes the following steps:

[0140] In step S602, the base station eNB configures and sends SC-MCCH information.

[0141] This step is similar to step S502, the difference is that the SC-MCCH includes: a counting request; wherein the counting request includes at least one or more: TMGI, that is, the SC-PTM service that needs to be counted, and the above TMGI can use the corresponding G- The RNTI is replaced, or the index number is used to indicate the order of the SC-PTM services in the SC-MCCH, for example, the first service in the SC-MCCH is identified by the index number 1.

[0142] Step S604, UE reads SC-MCCH information.

[0143] This step is the same as step S504 and will not be repeated here.

[0144] In step S606, the UE judges whether it is in the RRC-Connected state, if yes, go to step S608, otherwise go to step S618.

Embodiment 2

[0161] The scenario of this embodiment is that the SC-MCCH includes a channel quality indication CQI feedback request; for example Figure 7 As shown, the process includes the following steps:

[0162] In step S702, the base station eNB configures and sends SC-MCCH information.

[0163] This step is similar to step S502, except that the SC-MCCH includes: CQI feedback request; the CQI feedback request includes CQI feedback criteria, specifically at least includes: feedback threshold, that is, the channel condition for CQI feedback, assuming feedback Threshold = 3dB, when the UE measures the downlink channel SINR / SNR<3dB, the UE reports the CQI. Without loss of generality, the above feedback request can also be a value in the CQI table, such as 5, then when the UE measures and calculates Report the CQI when the CQI value is lower than 5, otherwise the CQI will not be reported; whether the CQI can be reported and how to report the CQI need to be consistent with the existing spec...

Embodiment 3

[0176] The scenario of this embodiment is that SC-MCCH contains ACK / NACK request information, such as Figure 8 As shown, the process includes the following steps:

[0177] In step SS802, the base station eNB configures and sends SC-MCCH information.

[0178] This step is similar to step S502, except that the SC-MCCH includes: ACK / NACK feedback request; the ACK / NACK feedback request includes at least: NACK feedback, and further includes: whether RRC-Idle UE needs feedback, that is, RRC- Whether the Idle UE needs to enter RRC-Connected and then report. The NACK feedback means that the UE reports only after confirming that it is a NACK, and the ACK does not need to be reported.

[0179] Without loss of generality, the above feedback request may also be whether ACK / NACK is reported, that is, both ACK / NACK is fed back or neither is fed back.

[0180] Optionally, the ACK / NACK request further includes: an SC-PTM service identifier, such as TMGI or G-RNTI, and may also be an index...

Abstract

The invention provides an SC-MCCH sending method, an SC-PTM receiving method and a device thereof. The SC-MCCH sending method comprises steps that a base station generates SC-MCCH used for indicating configuration information of an SC-PTM service; and the base station sends the SC-MCCH, wherein the SC-MCCH comprises a mapping relation between an identifier (TMGI) of the SC-PTM service and an identifier (G-RNTI), on a physical layer, of the SC-PTM service, the time domain information of the SC-PTM service and a modulation coding scheme (MCS) of the SC-PTM service. According to the invention, a problem of the failure to give out an effective scheme for scheduling the SC-PTM service in the prior art is solved; and the scheduling of the SC-PTM service is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an SC-MCCH sending method, an SC-PTM receiving method and a device thereof. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertisements, online education, interactive games, etc. On the one hand, it meets the multi-service requirements of mobile users, and at the same time 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. [0003] In order to effectively utilize mobile networ...
