METHOD, BASE STATION AND USER EQUIPMENT FOR TRANSMITTING PHYSICAL RESOURCE BLOCK AND CHANNEL ESTIMATING |
摘要 |
<p>Embodiments of the present invention provide a method, a base station and a user equipment for transmitting physical resource blocks and estimating channels. The transmitting physical resource blocks includes: scheduling, by a base station, M physical resource blocks (PRBs) for the user equipment, and configuring reference signal patterns for the M PRBs, where the method for configuring the reference signal patterns includes: allocating (X-1)M+1 1 demodulation reference signal subcarriers for M PRBs in a frequency domain, and based on a boundary of every two PRBs, configuring only one demodulation reference signal subcarrier within a range of (-N, N] subcarriers in the border of every two PRBs, where locations of the rest (X-2)M+2 demodulation reference signal subcarriers keep consistent with locations of demodulation reference signal subcarriers in M contiguous first demodulation reference signal patterns in a frequency domain; and transmitting the configured M PRBs to the user equipment, so that the user equipment performs joint channel estimation according to the configured M PRBs. This saves reference signal overheads and optimizes data transmission rate.</p> |
