Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a broadcast/television basic carrier bandwidth.
Background
An LTE (Long Term Evolution) system downlink and uplink are respectively based on OFDMA (Orthogonal Frequency Division Multiple Access) and SC-FDMA (Single-carrier Frequency Division Multiple Access), a time-Frequency resource is divided into time-domain symbols in a time-domain dimension and subcarriers in a Frequency-domain dimension, and a minimum resource granularity is called an RE, i.e., a time-Frequency lattice point composed of one time-domain symbol in the time domain and one subcarrier in the Frequency domain. The transmission of traffic in the LTE system is based on base station scheduling, and the basic time unit of scheduling is one subframe, and one subframe includes multiple time domain symbols. The specific scheduling procedure is that the base station sends a Control Channel, for example, a PDCCH (Physical Downlink Control Channel), where the PDCCH may carry scheduling information of a PDSCH (Physical Downlink Shared Channel) or a PUSCH (Physical Uplink Shared Channel), and the scheduling information includes Control information such as resource allocation and coding adjustment. And the user equipment detects the control channel in the subframe and receives a downlink data channel or transmits an uplink data channel according to the detected scheduling information carried in the control channel.
The bandwidth of a carrier in the LTE system may have various values, and may be specifically selected from a set {1.4,3,5,10,15,20} MHz, which are generally referred to as standard bandwidths. However, bandwidth division of the spectrum of radio and television generally does not comply with the standard bandwidth of LTE, for example, 8MHz or even 7 or 6 MHz. And the downlink control channel and the cell common pilot frequency of the LTE are mapped in a full frequency band and cannot be directly expanded into the nonstandard bandwidth of the radio and television.
