Method and base station for sending resource blocks and performing combined channel estimation, and user equipment

Abstract

An embodiment of the invention provides a method and a base station for sending resource blocks (RBs) and performing combined channel estimation, and a piece of user equipment. The method of sending the resource blocks comprising that: demodulation pilot of an RB group used for performing combined channel estimation is configured for the user equipment by the base station, so that resource unit RE number occupied by the demodulation pilot of each RB in a demodulation pilot pattern after the configuration is less than or equal to N (N=XY), and the total number of RE occupied by the demodulation pilot in the RB group is less than N*M, wherein, the RB group is a combination of a plurality of RBs, M is the number of RBs included in the RB group, X is the number of OFDM symbols occupied by the demodulation pilot configured in a single RB on performing the single RB channel estimation, and Y is the number of subcarriers occupied by the demodulation pilot in each OFDM symbol, in which the demodulation pilot configured in the single RB is located, when the single RB channel estimation is performed. The method can correspondingly configure the pilot according to the number of the resource blocks from the combined channel estimation, thereby saving the transmission resources and increasing the data transfer rate.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method for sending resource blocks and performing joint channel estimation, a base station, and user equipment. Background technique [0002] The pilot frequency can be inserted into the resource blocks of the data frame in a centralized form or a uniform discrete form, and is used for channel estimation in the communication system network. The pilot structure in each resource block is a pre-configured dedicated pilot structure. Generally speaking, one resource block can be used to estimate the channel alone, and multiple resource blocks (Resource Blocks, RB for short) can also be used to jointly estimate the channel. [0003] In the prior art, when multiple resource blocks are used to jointly estimate the channel, if the pilot structure used for channel estimation of a single resource block is followed, resources will be wasted.
