Description

Method and equipment for processing reference demodulation pilot frequency

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing a reference demodulation pilot in the field of wireless communications.

Background

In a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM) technology, generally, a reference demodulation signal of a control channel and the control channel are multiplexed by a mixed manner of time Division and Frequency Division, and it is characterized in that a reference demodulation pilot Frequency corresponding to the control channel exists in an OFDM symbol where the control channel is located; the reference demodulation pilots of the data channel and the data channel are also multiplexed in the same way, and within the OFDM symbol of the data channel, the reference demodulation pilot corresponding to the data channel may exist. In a Long Term Evolution (LTE) system, in a Resource Block (RB) of a basic time interval (subframe) frequency domain, a channel and reference demodulation signal map is shown in fig. 1, and a definition of the Resource Block is shown in fig. 2.

In Release 8, both the Control CHannel and the data CHannel use Cell specific pilot (CRS) for Reference demodulation, the CRS is embedded in OFDM symbols of a Physical Downlink Control CHannel (PDCCH) and a Physical Downlink Shared CHannel (PDSCH), and the PDCCH and the PDSCH are multiplexed in a time division manner using different OFDM symbols within a subframe.

In Release 9 and later versions, a special Demodulation pilot (DMRS) is introduced, control is still demodulated based on CRS, and data is demodulated based on the newly introduced DMRS.

A new Enhanced Control Channel (EPDCCH) is introduced in Release11 and later versions, the EPDCCH is demodulated based on DMRS within the same RB, the PDSCH is also demodulated based on DMRS within the same RB, and the EPDCCH and the PDSCH use different RBs for transmission in a frequency division multiplexing manner.

In the OFDM system, it can be found that the prior art has at least the following problems:

problem 1: the reference demodulation pilots for data or control are embedded in the OFDM symbols where the data channel and the control channel are located and distributed very discretely in the time domain. The problems that this approach can lead to are: the receiving end needs to receive and buffer the last OFDM symbol containing the reference demodulation pilot frequency first, and then starts to perform channel estimation processing of the pilot frequency, and then performs demodulation of data or control, which may cause an increase in processing delay; the pilot frequency and data/control are mixed with the OFDM symbol, so that some parameter settings of the OFDM symbol need to simultaneously consider the characteristics of the pilot frequency and the characteristics of the data, the flexibility is influenced, and the targeted optimization cannot be performed.

Problem 2: the data channel and the control channel use the exact same pilot in earlier versions, which may lead to significant flexibility limitations, since the control and data may use different Multiple-Input Multiple-Output (MIMO) transmission techniques, number of layers, etc. The use of completely independent pilots in the later version may cause a problem of inefficient pilot utilization, because the corresponding multi-antenna physical channels are the same during control and data transmission, and there is an obvious correlation between demodulation pilots.

The reference demodulation pilot processing method according to the embodiment of the present invention is further described below with reference to specific application scenarios.

Application scenario one

The sending end can send two kinds of pilot frequency, which are a first kind of reference demodulation pilot frequency and a second kind of reference demodulation pilot frequency respectively, wherein the first kind of reference demodulation pilot frequency is used for control channel reference demodulation and data channel reference demodulation; the second type of reference demodulation pilot frequency is used for data channel reference demodulation; there are several ways to implement this pilot transmission method, for example, the reference demodulation pilot of the control channel is port a, single-layer transmission is used, the reference demodulation pilot of the data channel is port a and port b (or more ports), and the data channel uses multi-layer transmission; as shown in fig. 15, the transmitting end transmits a port a, a port b, a control channel, and a data channel, and the receiving end demodulates the data and the control channel using the port a and is used for data channel demodulation using the port a and the port b.

Or, as shown in fig. 16, the control channel may demodulate only using the pilot on one time domain OFDM symbol at port a, so that the control channel may be demodulated quickly, and the data channel may use the pilot on multiple OFDM symbols at port a to perform joint channel estimation and then be used for reference demodulation of the data channel, which may improve the reference demodulation accuracy.

Application scenario two

In the above embodiments, only some simple mapping of pilots and channels are exemplified, and in this embodiment, more mapping relations of a channel and a signal are given, such as:

the first type of reference demodulation pilot frequency is positioned in front of the control information sending time domain position; such as shown in fig. 17.

The first type of reference demodulation pilot frequency part is positioned before the control information sending time domain position, and one part is positioned after the control information sending time domain position; such as shown in fig. 18.

The first type reference demodulation pilot and the second type reference demodulation pilot are located after the control information transmission time domain position and before the data information transmission, for example, as shown in fig. 19.

The first type of reference demodulation pilot and the second type of reference demodulation pilot are both located before the time domain position of control information transmission, for example, as shown in fig. 20.

Application scenario three

A base station determines a reference demodulation pilot frequency corresponding to data and/or control information to be sent;

the base station determines the time domain position relation between the reference demodulation pilot frequency and the control channel and/or the data channel to be transmitted;

and the base station transmits the reference demodulation pilot frequency according to the determined time domain position relation.

A specific time domain positional relationship is introduced below:

within a basic time interval unit, such as a subframe, or within a time range of a plurality of aggregated subframes; the basic time unit is not limited to a subframe, and may be a time slot, a time domain symbol group, or the like; but needs to contain the reference demodulation pilot signal and the control channel associated with the data channel;

the reference demodulation pilot signal associated with the data channel is transmitted using symbols in the second time domain symbol set; the control channel is transmitted using a third set of time domain symbols; all symbols comprised by the second time domain symbol set precede the symbols comprised by the third time domain symbol set as shown in fig. 21.

The reference pilot frequency and the channel in the mode are independent symbols, and the configuration of different symbol parameters can be considered respectively; reference signals of control and data, and different reference signal ports can be considered by introducing some frequency division ways, such as respectively occupying different subcarriers.

Application scenario four

transmitting a reference demodulation pilot signal associated with the data channel using a second set of time domain symbols;

the control channel is transmitted using a third set of time domain symbols;

the data channel is transmitted using a fourth set of time domain symbols;

all symbols contained in the second time domain symbol set are located after the symbols contained in the third time domain symbol set and all symbols contained in the second time domain symbol set are located before the symbols contained in the fourth time domain symbol set; as shown in fig. 22.

Application scenario five
