example 1

[0038] Step 1, set MC-RNTI=0xFFFC, the specific definition value of MC-RNTI is as shown in table 1; The network side (system) is set MC-RNTI information in the DCI of subframe PDCCH (specific placement position is related to BCCH) Indicate in the SIB), and set the specific content of the MCCH in the PDSCH corresponding to the MC-RNTI message;

[0039] Step 2, the terminal reads the relevant SIB in the BCCH, and obtains the location information of the MC-RNTI and the corresponding MCCH (that is, the location information of the above-mentioned MC-RNTI) through the SIB;

[0040] Step 3: According to the location information of the MC-RNTI and the corresponding MCCH, the terminal performs blind detection and decoding on the relevant subframe PDCCH. If the detected RNTI is the MC-RNTI, then according to the message corresponding to the MC-RNTI, it can be obtained The position of the MCCH in the PDSCH, and receive the PDSCH at the corresponding position, and report the decoded MCCH ...

[0046] Step 1. According to the specifications of the 3rd Generation Partnership Project (3GPP for short), MBMS bearer services can be divided into two types: download type (Download) and stream type (Stream). In order to distinguish these two types of services and speed up the search speed of terminals, two RNTIs are defined on the network side: MC d -RNTI and MC s -RNTI, where, MC d - RNTI corresponds to download business, MC s - RNTI corresponds to streaming services;

[0047] Step 2, the network side will MC d / s - RNTI information is set in the DCI of the subframe PDCCH (the specific placement position is indicated in the relevant SIB on the BCCH), and the corresponding MCCH specific content is set in the MC d / s -in the PDSCH corresponding to the RNTI message;

[0048] Step 3, the terminal reads the relevant SIB in the BCCH, and obtains the M from the SIB d / s - RNTI and corresponding MCCH location information;

[0049] Step 4, according to MC d / s - RNTI and the loc...

Abstract

The invention discloses a method and a terminal for indicating resources. The method comprises the steps that: the terminal acquires position information of a multicast control channel radio network temporary identity MC-RNTI which is used for indicating resource allocation of a multicast control channel on a broadcast control channel; and the terminal acquires the MC-RNTI in a physical downlink control channel according to the position information of the MC-RNTI. By the information indication of the MC-RNTI, the terminal can acquire the resource position of an MCCH in the single-cell or multi-cell mode so as to acquire control information related to a multicast service, simplify the complexity of a system, reduce power consumption of the terminal and improve the service efficiency of an MBMS.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a resource indication method and a terminal. Background technique [0002] Currently, in multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS for short) communication, a point-to-multipoint multicast control channel (Multicast Control Channel, MCCH for short) is used to transfer control plane information between a terminal and a network. On the MCCH, information related to the structure of MBMS in a specific cell and network can be provided, and related information about the currently opened MBMS and its identifier, as well as related information about service bearers and neighboring cells can also be provided. [0003] In related technologies, the MCCH can adopt a layered structure, which is divided into a primary control channel (Primary MCCH, referred to as P-MCCH) and a secondary control channel (Secondary MCCH, referred to as S-M...
