Embodiment Construction
[0064] In order to make the purpose, design scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0065] A schematic diagram of an embodiment of the delay-optimized resource allocation method in the present invention, as shown in figure 1 As shown, when the radio resource manager executes the user scheduling and service priority determination process, the radio resource manager first obtains the QSI of each service corresponding to each service of each user from the baseband processor buffer area, and determines all the QSIs in the current time slot Uplink users that need to be scheduled, and then obtain the CSI reported by all users to be scheduled in the current time slot through the uplink control channel;
[0066] The wireless resource manager obtains the QSI of each service corresponding to each service of each user to be scheduled from the bu...

The invention discloses a resource allocation method for time-delay optimization, which relates to the field of wireless communication technologies. The resource allocation method comprises the steps of: firstly, determining users to be scheduled on a current time slot by means of a wireless resource manager, calculating a priority factor of each service of the users to be scheduled according to QSI of all the users to be scheduled on the current time slot and a previous time slot, and generating a user service priority order table which is used for instructing decisions of the wireless resource manager in controlling transmission power required for transmitting data of the service with the highest priority of the users to be scheduled and allocating wireless resource blocks, and then transmitting resource allocating results to the corresponding users to be scheduled; and finally, updating the QSI of a buffer queue corresponding to each service of each user. The resource allocation method for time-delay optimization ensures the boundedness of all the buffer queues in a network, so as to reduce the average transmission time delay of the services, and makes network energy efficiency performance approaching the optimal value on the premise of realizing network stability.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a time-delay-optimized resource allocation method in a wireless access network. Background technique [0002] According to Cisco's public research report in 2016, more than 55% of data traffic currently comes from video streaming and voice conversation services. Such delay-sensitive real-time services will continue to grow exponentially in the next five years. In 2020, the data traffic generated by real-time services will account for more than 75% of the total data traffic. Therefore, in order to ensure that the real-time services run by smart terminals such as smartphones, tablets, and wearable devices can bring customers a better user experience, mobile Internet applications place higher requirements on the delay performance of wireless networks. [0003] Real-time services require low latency in wireless networks so that traditional resource allocation ...
