XR is a broad definition containing augmented reality, mixed reality, and virtual reality. Different from URLLC, XR traffic has multiple periodic data streams for one user. Based on the analysis of XR, the paper investigates some enhanced resource allocation and scheduling schemes to improve the user experience, while maintaining low power consumption and resources. It is proposed to introduce a playout buffer at UE to improve scheduling flexibility. In addition, to assist the gNB allocate the resource more efficiently, the priority classification and time-aligned transmission mechanisms are introduced. Finally, the paper demonstrates that joint resource allocation and scheduling optimization schemes can significantly reduce resource and power consumption.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"65 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88673091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the SVD algorithm, the channel matrix composed of the maximum KL singular vector is obtained by SVD decomposition of the received signal covariance matrix. At this time, the estimation matrix has a certain ambiguity, and then the LS algorithm of the short pilot sequence is used to accurately estimate the channel matrix. This channel estimation scheme is unbiased in the ideal case, but in the actual implementation, the average approximation of the covariance matrix of the received signal is required, which leads to the deterioration of the actual channel matrix estimation, which is quite different from the theoretical value. Therefore, we derive the closed mean square error (MSE) of the channel estimation that characterizes the above error sources, so as to deeply understand the influence of the above error sources on the estimation algorithm. And compare with Cramer-Rao bound(CRB). The data results verify this analysis.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"45 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84814925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown that wireless caching is a successful method for resolving the conflict between the massive data traffic and the limited transmission rate. This study looks at a software-defined network caching strategy that uses two separate caches on mobile devices to store files with different popularity using different caching methods. It is possible to download the requested files locally, through device-to-device collaboration, or from cellular network. The cooperative caching strategy also aims to increase the cache hit probability. According to simulation results, the cache hit probability has been optimized through the caching strategy.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"29 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86961171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deployment of integrated communication terminals affects the access range and service QoS of power service terminals. To address this issue, this paper investigates the deployment of multi-link integrated communication terminals in 5G integrated power communications network and proposes a multi-link integrated communication terminal deploying method to support the wide coverage of power 5G. Firstly, a multi-link optimization model for wide coverage 5G integrated networks containing coverage indicator, multi-service QoS indicator and cost indicator is constructed to optimize the location deployment scheme of integrated communication terminals. Based on this, an improved artificial fish swarm-based multi-link integrated communication terminal location deployment optimization algorithm is proposed to solve the high-dimensional decision space optimization problem of integrated communication terminal deployment. Simulation results show that the algorithm proposed in this thesis can rapidly find the optimal integrated communication terminal deployment location with limited cost budget, significantly improve the network coverage and service QoS indicator.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"36 3 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78059687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
