example 1

[0122] This example mainly describes the scheme of selecting a component carrier for sending MCCH change information by adopting high-layer signaling configuration mode, and using M-CI-RNTI for scrambling indication. The following combination Figure 5 to describe.

[0123] Such as Figure 5 As shown, it is assumed that there are three carriers CC1, CC2, CC3. CC3 is an extension carrier, and there are 2 component carriers in the UE's PDCCHCCset (component carrier set), denoted as CC1 and CC2.

[0124] Since the extended carrier CC3 has no PDCCH, the multicast control channel change information of the extended carrier can be sent on other component carriers as indicated by high layer signaling.

[0125] The M-CI-RNTI allocated to CC3 by high-layer signaling is FFFC (hexadecimal).

[0126] When the base station sends the multicast control channel change information of the extended carrier CC3 on the component carrier CC2 through high-level signaling, the CRC of the correspon...

example 2

[0130] This example mainly describes that a component carrier for sending multicast control channel change information is selected in a random selection manner, and the newly defined downlink control information format DCIformatX is used for indication. The following combination Figure 5 to describe.

[0131] Such as Figure 5 As shown, it is assumed that there are three carriers CC1, CC2, CC3. CC3 is an extension carrier, and there are 2 component carriers in the UE's PDCCHCCset (component carrier set), denoted as CC1 and CC2.

[0132] The UE needs to obtain the multicast control channel change information of CC1, CC2 and CC3. Then the UE blindly detects the multicast control channel change information of CC1 on the component carrier CC1, blindly detects the multicast control channel change information of CC2 on the component carrier CC2, and performs detection on the carriers of the component carrier set, for example, on CC1 and CC2 The multicast control channel change ...

Abstract

The present invention discloses that a base station selects a first component carrier among multiple component carriers; and the base station transmits MCCH change information corresponding to a second component carrier to a user equipment on the first component carrier, wherein the second component carrier is the same or different from the first component carrier. According to the technical solution provided by the present invention, dynamic transmission of multicast control channel change information in a multi-component carrier scenario can be realized, and correct acquisition of the multicast control channel change information by user equipment can be realized.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for transmitting MCCH change information. Background technique [0002] In order to meet the requirements of the International Telecommunication Union-Advanced (ITU-Advanced for short), the Long Term Evolution Advanced (LTE-A for short) system, which is an evolution standard of the Long Term Evolution (LTE for short), needs to support more Large system bandwidth (up to 100MHz), and needs to be backward compatible with existing LTE standards. On the basis of the existing LTE system, the bandwidth configuration of the LTE system can be combined to obtain a larger bandwidth. The above-mentioned technology is called carrier aggregation (CarrierAggregation, referred to as CA) technology. The spectrum utilization rate of an Intelligent Multimode Terminal (IMT-Advance for short) system can alleviate the shortage of spectrum resources, thereby optimizing the uti...
