Description
技术领域technical field
本发明涉及通信技术领域，尤其涉及一种对广电基本载波带宽进行配置的方法和装置。The invention relates to the technical field of communication, in particular to a method and a device for configuring the basic carrier bandwidth of broadcasting and television.
背景技术Background technique
LTE(Long Term Evolution，长期演进)系统下行和上行分别基于OFDMA(Orthogonal Frequency Division Multiple Access,正交频分多址)和SC-FDMA(Single-carrier Frequency-Division Multiple Access，单载波频分多址)，时频资源被划分成时间域维度上的时域符号和频率域维度上的子载波，而最小的资源粒度叫做一个RE，即表示时间域上的一个时域符号和频率域上的一个子载波组成的时频格点。LTE系统中业务的传输是基于基站调度的，调度的基本时间单位是一个子帧，一个子帧包括多个时域符号。具体的调度流程是基站发送控制信道，比如PDCCH(Physical Downlink Control Channel，物理下行控制信道)，PDCCH可以承载PDSCH(Physical Downlink Shared Channel，物理下行共享信道)或PUSCH(Physical Uplink Shared Channel，物理上行共享信道)的调度信息，该调度信息包括比如资源分配、调整编码方式等控制信息。用户设备在子帧中检测控制信道，并根据检测出的控制信道中承载的调度信息来进行下行数据信道的接收或上行数据信道的发送。LTE (Long Term Evolution, long-term evolution) system downlink and uplink are based on OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) and SC-FDMA (Single-carrier Frequency-Division Multiple Access, single-carrier Frequency-Division Multiple Access, respectively) ), time-frequency resources are divided into time-domain symbols in the time-domain dimension and subcarriers in the frequency-domain dimension, and the smallest resource granularity is called an RE, which means a time-domain symbol in the time domain and a sub-carrier in the frequency domain A time-frequency grid composed of subcarriers. The transmission of services in the LTE system is based on base station scheduling, and the basic time unit of scheduling is a subframe, and a subframe includes multiple time domain symbols. The specific scheduling process is that the base station sends a control channel, such as PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel), and PDCCH can carry PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) Channel) scheduling information, the scheduling information includes control information such as resource allocation, adjustment of coding mode, and so on. The user equipment detects the control channel in the subframe, and receives the downlink data channel or sends the uplink data channel according to the scheduling information carried in the detected control channel.
LTE系统中一个载波的带宽可以有多种取值，具体可以从集合{1.4,3,5,10,15,20}MHz中选取，一般把这几种带宽称为标准带宽。但是广电的频谱的带宽划分一般都不遵循LTE的标准带宽，例如，8MHz甚至是7或6MHz。而且LTE的下行控制信道和小区公共导频都是全频带映射的，无法直接扩展到广电的非标带宽中。所以现有技术存在广电基本载波带宽不支持LTE标准带宽的问题。The bandwidth of a carrier in the LTE system can have multiple values, specifically, it can be selected from the set {1.4, 3, 5, 10, 15, 20} MHz, and these types of bandwidths are generally called standard bandwidths. However, the bandwidth division of radio and television spectrum generally does not follow the standard bandwidth of LTE, for example, 8MHz or even 7 or 6MHz. Moreover, the downlink control channel of LTE and the common pilot frequency of the cell are all mapped to the whole frequency band, which cannot be directly extended to the non-standard bandwidth of radio and television. Therefore, there is a problem in the prior art that the basic carrier bandwidth of radio and television does not support the LTE standard bandwidth.
