Embodiment 1

[0108] In this embodiment, a method for processing configuration information of channel state information pilot resources is provided, Image 6 It is a flowchart of a method for processing channel state information pilot resource configuration information according to an embodiment of the present invention, such as Image 6 As shown, the process includes the following steps:

[0109] Step S602: Determine configuration information of the channel state information pilot resource, where the configuration information includes at least one of the following: the code division multiplexing type of the channel state information pilot resource, the number of ports of the channel state information pilot resource, The density of the channel state information pilot resource, the sequence number of the channel state information pilot configuration used to aggregate the channel state information pilot resource, the offset position of the channel state information pilot configuration in the frequ...

Embodiment 1

[0252] In this optional embodiment, the base station first determines the configuration information of the channel state information pilot resource, then generates signaling including the configuration information of the channel state information pilot resource, and then transmits the configuration information including the channel state information pilot resource Signaling. The configuration information of the channel state information pilot resource includes: the channel state information pilot code division multiplexing category, the number of ports of the channel state information pilot resource, and the density of the channel state information pilot resource to aggregate into The sequence number of the channel state information pilot configuration of the channel state information pilot resource, and the offset position of the channel state information pilot configuration in the frequency domain. Wherein, the resource unit pattern of the configuration is at least jointly de...

Embodiment 2

[0268] In this embodiment, the configured resource unit pattern is at least jointly determined by the code division multiplexing type, the configured sequence number, and the number of ports of the channel state information pilot resource.

[0269] For example, as shown in Table 6(a), the resource unit pattern of the configuration is jointly determined by the code division multiplexing type, the sequence number of the configuration, and the number of ports of the channel state information pilot resource; or, as shown in Table 6( As shown in b), the resource unit pattern of the configuration is jointly determined by the code division multiplexing type, the sequence number of the configuration, the number of ports of the channel state information pilot resource, and the number of ports of the channel state information pilot configuration.

Abstract

The invention provides a configuration information processing method and device, a base station and a terminal. The method comprises the following steps: determining configuration information of a channel state information pilot resource, wherein the configuration information includes at least one of the following: the code division multiplexing category of the channel state information pilot resource, the port number of the channel state information pilot resource, the density of the channel state information pilot resource, the serial number of channel state information pilot configuration for aggregating the channel state information pilot resource, and the bias position of the channel state information pilot configuration in a frequency domain, and a resource unit pattern of the channel state information pilot configuration is determined jointly by at least the code division multiplexing category and the serial number; and generating a signal including the configuration information, and transmitting the signal. Through adoption of the configuration information processing method and device, the base station and the terminal, the problem of relatively high transmission complexityof channel state information pilot CSI-RS (CSI-Reference Signal) in the prior art is solved, thus achieving the effect of lowering the transmission complexity of the channel state information pilot CSI-RS.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for processing configuration information, a base station, and a terminal. Background technique [0002] Long Term Evolution (LTE) / Long Term Evolution (LTE-A, LTE-Advanced) technology is the mainstream fourth-generation mobile communication technology (4G). LTE / LTE-A is divided into the following two different duplex modes: Frequency Division Duplex (FDD for short) and Time Division Duplex (TDD for short). The frame structure of the frequency division duplex mode is called the first type frame structure (Frame structure type 1), and the frame structure of the time division duplex mode is called the second type frame structure (Frame structure type 2). [0003] figure 1 It is a schematic diagram of the first type of frame structure. Such as figure 1 As shown, the description of the first type of frame structure is as follows: each radio frame (radio frame) i...
