Problems solved by technology

[0015] Since (e)MBMS is a one-way downlink service, there is no statistical mechanism for the relevant MBMS error rate in the actual system. For example, it is impossible to count coverage holes in the MBSFN (MBMS Single Frequency Network, MBMS Single Frequency Network) area, etc.

Embodiment 1

[0177] On the network side, such as image 3 As shown, the network device sends an MCCH in subframe t1, and uses the MCCH to indicate the first MCS level used for MTCH transmission, and starts to use the first MCS level for MTCH transmission from subframe t2. Thereafter, the network device sends an MCCH in subframe t3, through which the MCCH is used to indicate the second MCS level used for MTCH transmission, and starts to use the second MCS level for MTCH transmission in subframe t4.

[0178] On the terminal side, the terminal receives the MCCH in subframe t1, and according to the first MCS level indicated by the MCCH, starts to receive the MTCH transmitted using the first MCS level in subframe t2, and counts the errors of the MTCH transmitted using the first MCS level information. Thereafter, the terminal receives the MCCH at subframe t3, and according to the second MCS level indicated by the MCCH, starts to receive the MTCH transmitted at the second MCS level at subframe t...

Embodiment 2

[0190] On the network side, such as Image 6 As shown, the network device sends SIB13 in subframe t1, and uses the SIB13 to indicate the first MCS level used for MCCH transmission, and starts to use the first MCS level for MCCH transmission from subframe t2. Thereafter, the network device sends SIB13 in subframe t3, through which the SIB13 indicates the second MCS level used for MCCH transmission, and starts to use the second MCS level for MCCH transmission in subframe t4.

[0191] On the terminal side, the terminal receives SIB13 in subframe t1, and according to the first MCS level indicated by the SIB13, starts to receive the MCCH transmitted using the first MCS level in subframe t2, and counts the MCCH transmitted using the first MCS level error message. Thereafter, the terminal receives SIB13 in subframe t3, and according to the second MCS level indicated by the SIB13, starts to receive MCCH transmitted using the second MCS level in subframe t4, and starts to count the MC...

Embodiment 3

[0201] On the network side, the network device sends SIB13 in subframe t1, through which the SIB13 indicates the first MCS level used for MSI transmission, and starts to use the first MCS level for MSI transmission from subframe t2. Thereafter, the network device sends SIB13 in subframe t3, and indicates the second MCS level used for MSI transmission through the SIB13, and starts to use the second MCS level for MSI transmission in subframe t4.

[0202] On the terminal side, the terminal receives SIB13 in subframe t1, and according to the first MCS level indicated by the SIB13, starts to receive MSI transmitted using the first MCS level in subframe t2, and counts the MSI transmitted using the first MCS level error message. Thereafter, the terminal receives SIB13 in subframe t3, and according to the second MCS level indicated by the SIB13, starts to receive MSI transmitted using the second MCS level in subframe t4, and counts the MSI transmitted using the second MCS level from s...

Abstract

The invention discloses a channel quality statistics method and equipment. The method comprises the following steps that: a terminal receives first signaling transmitted by network equipment, wherein the first signaling is used for indicating that the network equipment is about to transmit first type downlink information by using a first MCS level; and the terminal performs error information statistics on the first type downlink information transmitted by using the first MCS level from a first sub-frame, and ends the error information statistics on a second sub-frame, wherein the first sub-frame is a sub-frame on which the network equipment starts to transmit the first type downlink information by using the first MCS level determined by the terminal according to the first signaling, the second sub-frame is a sub-frame on which the network equipment starts to transmit the first type downlink information by using a second MCS level determined by the terminal according to second signaling transmitted by the network equipment, and the first MCS level is different from the second MCS level. Through adoption of the channel quality statistics method and equipment, statistics of error information of MBMS (Multimedia Broadcast Multicast Service) downlink information can be realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel quality statistics method and equipment. Background technique [0002] In order to reduce manual participation in network planning and operation and maintenance, reduce network construction and operation costs, and obtain wireless measurement information in areas that cannot be reached by ordinary drive tests, the LTE (Long Term Evolution, Long Term Evolution) system of the Rel-10 version and In the UMTS (Universal Mobile Telecommunications System, universal mobile communication system) system, MDT (Minimization of Drive Tests, minimum drive test) is introduced. Existing MDT processes include: [0003] (1) Logged MDT: The terminal obtains the logged MDT configuration through dedicated signaling in the RRC (Radio Resource Control, radio resource control) connection state. After the terminal enters the idle state, the MDT measurement result is collected, ...
