Method for determining upper limit of transmission rate of self-adaptive collaborative wireless multicast communication data

Abstract

The invention relates to a method for determining the upper limit of a transmission rate of self-adaptive collaborative wireless multicast communication data, which comprises the following steps of: 1) detecting the capacity ISD (International Subscriber Dialing) 1 of a channel for information transmission between eNB and a UE (unified equipment) and the capacity of a channel for information transmission between an RN (radio network) and the UE; 2) acquiring the self-adaptive gate threshold ADTR1 of the channel between the eNB and the UE; 3) acquiring the self-adaptive gate threshold ADTR2 between the RN and the UE; 4) making the eNB send a group of multimedia data to M UEs and N RNs in a community; 5) if the UEs of Cf groups of users in G2 groups of users do not successfully receive the multimedia data sent by the eNB, making N RNs retransmit the data to Cf groups of users at a rate of R2; and 6) determining the equivalent data transmission rate of self-adaptive collaborative wireless multicasting communication. The difference between the self-adaptive method for the rate of the existing collaborative wireless multicasting transmission system and the upper limit of the data transmission rate of the system is demonstrated, and a trend can be provided for future self-adaptive development of the rate of the whole system.

Description

technical field [0001] The invention designs a method for determining the upper limit of data transmission rate of adaptive cooperative wireless multicast communication. Background technique [0002] With the continuous emergence of new mobile communication technologies, mobile communication networks can bring us higher bandwidth and faster data transmission rates. However, the essence of network transmission in this evolution process is still to allocate an independent channel for data transmission. No matter in the 3G, B3G or 4G mobile communication system, the base station must allocate a dynamic channel with non-interfering information to the users in its coverage area. When the number of users in the communication carrier sector continues to grow, the limited bandwidth resources will eventually be exhausted, and with the continuous popularization of multimedia large-capacity data transmission services, the situation of resource shortage will become more obvious, and ev...
