Background

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the background art and the detailed description, only a high-speed rail scene is taken as an example, and the scene to which the embodiment of the present invention is applied is not limited to this.

The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In an LTE network, a terminal performs channel estimation based on CRS for PDSCH demodulation. And the terminal obtains the time offset and frequency offset estimation of the channel from the CRS and finally completes the channel estimation. However, since the CRS signals received by the terminal are multipath superimposed from multiple RRH signals and different RRH doppler frequency offsets are different, complex frequency offset estimation needs to be performed to estimate frequency offsets on different RRHs respectively based on different frequency offset components in the superimposed CRS signals, and then channel estimation is performed.

In the high-speed rail deployment of a New Radio (NR) network of the Fifth generation mobile communication technology (5G), a deployment mode of RRH concatenation may also be considered. However, unlike LTE, the reference signal function used for time-frequency estimation in NR is assumed by Tracking RS (TRS), and TRS can occupy different resources on different RRHs for differentiation. The specific transmission form may include a TRS transmission mode 1 and a TRS transmission mode 2, where the TRS transmission mode 1: each RRH transmits a different TRS, see fig. 2; TRS transmission mode 2: two adjacent RRHs transmit different TRSs, see fig. 3.

That is to say, different terminals can estimate time offset and frequency offset for TRS signals on different resources, and especially when a train is located between two RRHs, signals transmitted by the two RRHs have opposite frequency offsets.

According to the NR current protocol design, the terminal performs channel estimation based on a Demodulation Reference Signal (DMRS) for PDSCH Demodulation, but performs time offset and frequency offset estimation based on the TRS associated with PDSCH DMRS before performing channel estimation, and completes channel estimation using information estimated from the TRS.

If the terminal can report the base station according to the measurement information on the TRS for the base station to perform the basis of the subsequent PDSCH service transmission, a proper RRH is selected to transmit the PDSCH, and the transmission performance can be improved.

However, according to the current NR protocol design, the terminal can only report the Channel State information Reference Signal Resource Index (CSI-RS Resource Index, CRI) based on the Channel State information Reference Signal (CSI-RS) measured by the Channel, and cannot report the Resource Index (Index) of the TRS. Referring to fig. 4, if a set of independent TRS and CSI-RS is configured under each RRH, the terminal reports the CSI-RS Resource Index measured by the channel, that is, associates with a unique TRS, and the base station may perform TRS configuration associated with a subsequent PDSCH according to information reported by the CSI.

However, each RRH transmits a set of independent TRS and CSI-RS, which results in increased system downlink signal overhead. The embodiment of the invention can obtain the advantage of accurately estimating the Doppler frequency offset by different RRHs on the premise of saving the reference signal configuration overhead, and realize the information report of the TRS, so that a base station end can select a proper RRH to transmit the PDSCH. In order to ensure the accuracy of Doppler frequency offset estimation, each RRH sends a TRS; to reduce overhead, multiple RRHs may share one CSI-RS.

However, the existing protocol cannot well support information reporting for a TRS, nor can it well support such a configuration that multiple RRHs share one CSI-RS, and each RRH transmits one TRS.

Table 1: the relation between the CSI-RS type and the reported quantity is supported in the relevant standard:

it can be seen that, for the TRS resource (which is also a CSI-RS in the protocol, but a TRS-info information flag is additionally configured, the TRS resource cannot report any CRI or Reference Signal Receiving Power (RSRP) information; only the channel state information reference signal (CSI-RS for L1-RSRP) used for the reference signal received power of layer 1 or the channel state information reference signal (CSI-RS for CSI acquisition) used for channel state information acquisition can report the CRI information. Both reference signals are associated to a certain TRS through corresponding Transmission Configuration Indication-State (TCI-State) Configuration, so that when a CRI is reported, the base station is correspondingly informed of which TRS is selected, but when a CSI-RS for L1-RSRP or a CSI-RS for CSI acquisition is associated with multiple TRSs, the optimal TRS information for the terminal cannot be determined only by the CRI reported by the terminal, so that some misallocation occurs when the TRSs associated with the PDSCH is configured subsequently.

In addition, in the existing NR protocol, only one TCI State can be configured for each Non-Zero Power Channel State Information Reference Signal resource (Non-Zero Power Channel State Information-Reference Signal resource, NZP CSI-RS resource), where at most a Quasi-Co-Location (QCL) relationship with two Reference Signals (RSs) is configured in the State (State), and the two QCL relationships must be different, and one CSI-RS cannot be configured to have the same QCL relationship with two different RSs, that is, when multiple RRHs share one CSI-RS, one CSI-RS needs to be associated to multiple TRSs, and the existing protocol cannot implement the configuration.

The technology described herein is not limited to a 5th-generation (5G) system and a later-evolution communication system, and is not limited to an LTE/LTE evolution (LTE-a) system, and may also be used for various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.
