一种终端能力信息上报、接收方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2017年5月5日在中国提交的中国专利申请号No.201710313282.4的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种终端能力信息上报、接收方法、终端及网络侧设备。
背景技术
LTE部分频段支持多个终端最大发射功率等级(power class),例如,band(频带)41power class 3对应的最大发射功率为23dBm,power class 2对应的最大发射功率为26dBm。
LTE拥有6个带宽配置[1.4,3,5,10,15,20]MHz,终端需要支持上述6个带宽配置。对于同一频段内固定power class下终端在不同带宽配置下的最大发射功率相同。带宽越小对应的功率谱密度越高,覆盖越好。
在5G系统设计中,既要考虑对legacy频段的继承,又要考虑对新频段超大带宽的支持,需要支持从[1.4,3,5,10,15,20,40,80,100,200,400…1000MHz]等带宽配置。系统最大带宽与最小系统带宽的比值将从原来的14倍扩大到700余倍。
终端在超大带宽工作时,为满足频谱辐射功率模板、邻频抑制比及杂散辐射等射频指标要求,对终端射频前端的功率放大器的线性度要求非常高。终端需要进行功率回退以使功放工作在线性度更高区域,满足上述射频指标要求。终端功率回退也意味着有效发射功率的降低,功放效率损失,功耗提升;终端在较小带宽工作时,功放可以工作在线性度较佳区域,功放效率较高,有效发射功率会相对超大带宽时提升。
若在5G系统支持从1.4MHz到10000MHz的带宽时,仍采用4G系统中保持终端在所有支持带宽内的最大发射功率不变的定义方式,将导致终端在较 小带宽工作时的功率余量浪费,相当于网络覆盖收缩,用户吞吐量下降。因此,需要采用更加灵活的终端最大发射功率的定义方式。
