Power allocating method capable of improving QoE of collaboration user

Abstract

The invention relates to a power allocation method for improving the user experience quality, which is used for the radio transmission technical field. In the invention, a source user firstly sends a collaboration request to collaboration user candidates on the periphery; then the collaboration user candidates who receive the request compare according to the following sequence to determine whether the collaboration user candidates can become collaboration users; the dump energy value and a dump energy threshold are compared, the quality of a channel is good, and energy consumed and the energy threshold consumed are compared. If the collaboration user candidates are selected as the collaboration users, collaboration confirmation is sent to the source user; then the source user sends power distribution information to the users on the periphery according to the total number of the collaboration confirmation received; and finally, after receiving the information, the collaboration users assist to forward data according to the distributed power value. The invention can improve the experience quality of the collaboration user in the collaboration communication, thereby ensuring that the collaboration user has enough dump energy to satisfy the communication demands thereof. The invention is applicable to B3G / 4G communication systems.

Description

technical field [0001] The invention relates to a power allocation method in the technical field of wireless communication, in particular to a power allocation method that can improve the QoE (quality of experience) of cooperative users in cooperative communication. Background technique [0002] With the rapid development of today's wireless communication services, users of wireless networks have an increasing demand for high-speed and high-performance voice, data and multimedia services. Therefore, next-generation wireless communication systems, such as B3G / 4G, will use advanced algorithms and techniques to improve data transmission rates and system performance. The multipath fading characteristic of wireless communication channels is one of the main reasons that limit the transmission rate and system performance, and diversity technology is the key technology to effectively combat multipath fading of wireless communication channels. Because it can provide significant spac...

Its shortcoming is that it ignores the deterioration of QoE (Quality of Experience) of collaborative users

As a result, the cooperative users do not have enough remaining power to meet their own communication needs, thus deteriorating the QoE of the cooperative users.

If the QoE of collaborative users is not improved or compensated accordingly, users and communication operators will take a negative and pessimistic attitude towards collaborative communication, and will not get support from users, which is not conducive to the promotion and application of collaborative communication in actual systems
