Description

Method and system for time division multiplexing transmission channel

Technical field

The present invention relates to the field of wireless communications, and in particular, to a method and system for time division multiplexing transmission channels.

Background technique

With the introduction of Multiple-Input Multiple-Output (MIMO) technology and beamforming technology in wireless communication systems, wireless access systems have become multi-antenna systems. With the introduction of spectrum aggregation technology, wireless communication systems have evolved from multi-antenna systems to multi-antenna multi-band (multi-carrier) systems.

The transmitting channel is the most costly functional module in the wireless communication system. If the number of configurations of the multi-antenna multi-band system transmission channel can be reduced by time-division multiplexing transmission channels without reducing system performance, the wireless communication system can be significantly reduced. the cost of.

The basis for reducing the number of transmission channels required for a multi-antenna multi-carrier wireless communication system by time-division multiplexing transmission channels is the following redundancy in a multi-antenna multi-channel system:

The first type of transmission channel redundancy - the same frequency point multi-carrier multi-antenna same cell (refers to the geographical area covered by multiple co-frequency carriers) The transmission channel redundancy existing in the system: in the same geographical cell, due to the terminal Different geographical locations result in different space-time channel characteristics of the terminal. Therefore, the number of antennas that different terminals can use in MIMO mode is different. Although for each terminal, the number of streams of multi-antenna multi-stream transmission or the order of MIMO channels that the space-time channel can support is random, but statistically, it can be used in one cell in one radio frame. The ratio of the terminal of the maximum antenna configuration of a cell to the serving terminal in the cell is statistically proportional. A terminal that serves a terminal that does not require high-order MIMO transmission, or a terminal that transmits to its full-time channel without transmitting to its full-time channel Within the time slot in which the service is provided, some of the transmit channels allocated to the cell are in a redundant state. Naturally, there are also redundancy in transmission resources and baseband processing resources corresponding to these transmission channels.

The second type of transmission channel redundancy - one multi-frequency point multi-carrier and the same coverage (refer to the same coverage of multiple carriers) Geographical regions, there are two or more carriers at each frequency.) Transmission channel redundancy in multiple antenna systems: As mentioned earlier, there is transmission channel redundancy in the cells covered by each carrier. That is, there are some time slots on which no part of the transmission channels can be used or used. In a system using carrier aggregation, there is a first type of redundancy for each carrier, and redundancy on these carriers introduces a new problem: Since each carrier has redundancy, it is necessary to have all carriers Configure according to the same number of antennas. This type of redundancy is referred to herein as inter-carrier transmit channel redundancy.

The third type of transmission channel redundancy - the redundancy between multiple sectors on one site: the multi-carrier multi-antenna system in each sector has transmission channel redundancy, and there are more between sectors redundancy. Even if each sector has a deduplication configuration, there will still be redundancy between the sectors, because the difference in the number of terminals or the number of services in different cells will result in statistics on the configuration of the transmission channels between the sectors. redundancy.

The fourth type of transmission channel redundancy - transmission channel redundancy in time division duplex (TDD) and frequency division duplex (FDD) composite systems: In the uplink time slot of the TDD system, the transmission channel configured for the TDD system is redundant. I/Idle state.

Category 5 Transmit Channel Redundancy There is transmit channel redundancy in TDD systems that configure uplink and downlink time slots asynchronously on the discontinuous TDD band: There is transmit channel redundancy on each TDD band.

The use of the above redundancy is the physical basis for implementing the time division multiplexing transmission channel, but there is currently no specific technical means.

Currently, there is a relatively concentrated study in the field of multi-standard radio (MSR: Multi-standard-radio) and software-defined radio (SDR: software defined radio). In the 3GPP standards organization, MSR has been discussed for a long time, but its reconfiguration method can not achieve the effect of reducing the transmission channel redundancy existing in these systems.

In the MSR discussed by the 3GPP, among the FDD-MSR and TDD-MSR that have been proposed, the multi-antenna and multi-carrier radio remote unit (RRU) are product forms stipulated by the 3GPP technical specifications, and all of the first to third types of redundancy are present. I. If further considering a new RRU physical entity: TDD/FDD MSR, then in the TDD/FDD-MSR, the above five transmission channel redundancy may exist. From the operator's demand for TDD/FDD hybrid networking, TDD/FDD-MSR integrated MSR for TDD RF channel and FDD RF channel will have a gradual market, but TDD/FDD MSR involves TDD and FDD RF channels. The coexistence problem, which is usually considered at this stage, is a type of device that has complex interference and is not practically meaningful. However, by reasonably selecting TDD, FDD band combination, the interference problem can be avoided, and because of its unique convenience in utilizing the transmission channel during the TDD uplink time slot, it is a device form that can reduce the overall cost. .

It should be particularly noted that, according to the detailed description in the specification of the present invention, "TDD" as used herein refers to half-duplex GSM, which is not the TDD used in the same frequency band in a time division manner as discussed in the present invention, and the problem to be solved is A configurable filter design is used to resolve how the transmit channel (Transmission Amplifier (PAT)) is shared between half-duplex (HD-FDD; GSM) and full-duplex FDD.

Related Art 2: Chinese Patent Application No. CN200980111947.7, entitled "Radio Frequency (RF) Signal Multiplexing" The technical solution given is: In a radio frequency (RF) receiver, the receiver RF chain is tuned to A first (eg, Global Positioning System (GPS)) channel permits admission of a first (eg, GPS) signal on a first (eg, GPS) channel on a receiver RF chain during a first duration. The receiver RF chain is tuned to a second (e.g., cellular paging) channel to permit a second (e.g., cellular paging) channel on the receiver RF chain during a second duration after the first duration The reception of a second (eg, cellular paging) signal. Processing the first duration And a first (eg, GPS) signal during the second duration, the first (eg, GPS) signal without any significant interruption during the second duration. For example, the process treats the actual interruption as a temporary short-term fading of the first (eg, GPS) signal during the second duration, or provides a bridge signal during the second duration (eg, an estimate on the receiver RF chain) GPS signal or actual GPS signal received on another receiver RF chain).

Preferred embodiment of the invention

The related art does not utilize differences in channel real-time characteristics, transmission link patterns, and service types between terminals receiving data on the same frequency band, giving time division multiplexing/statistical multiplexing between different frequency bands or between different antenna elements. The technical solution of the launch channel. In particular, there is no given method of utilizing the difference in the number of maximum radio frequency channels that can be used in a spatially multiplexed manner in terminals in different geospatial locations in a multi-antenna system.

Specifically, the related art does not provide a method of how to utilize the following resources in the above problem:

1) an idle transmission channel during the TDD uplink;

2) During the downlink time slot of the TDD or FDD system, a part of the TDD transmission channel or the FDD transmission channel is determined by the rank of the radio channel impulse response matrix between the terminal and the base station or determined by the service request of the terminal.

After taking a specific device architecture and effectively utilizing the statistical rules existing in the space-time channel characteristics between terminals existing in a multi-antenna system, and effectively utilizing the difference in downlink load between different frequency bands or between different cells, it can be significantly Reduce the number of transmission channels and reduce the cost of the system. Especially for TDD/FDD hybrid systems, and for systems in which TDD air interfaces are configured in pairs on two non-continuous frequency bands, the transmission channels of TDD can be multiplexed in other frequency bands, which can achieve flexible configuration between different technical specifications. Significantly reduce the basic configuration of the system for the number of RF channels, significantly reducing the cost of building a network.

Moreover, the related art also does not disclose and utilize the following mechanism that can reduce the number of transmitting channels: the difference in real-time characteristics of wireless channels between terminals in different geographical locations in a small area, especially the channel matrix between receiving channels of terminals Statistical differences in rank.

An embodiment of the present invention provides a method for time division multiplexing transmission channels, which implements time division multiplexing on one or more transmission channels in one of the following manners: (1) Time-division multiplexed transmit channels between a frequency band used in a time division duplex (TDD) mode and a downlink frequency band used in a frequency division duplex (FDD) mode;

(2) Time-division multiplexed transmit channels between the frequency band used in the TDD mode and the frequency band used in the one-way downlink mode (including the broadcast frequency band);

(3) Time-division multiplexed transmit channels between two frequency bands used in TDD mode;

(4) Time-division multiplexing transmission channels between two downlink frequency bands used in FDD mode;

(5) time-division multiplexing transmission channels between the first group of antenna elements and the third group of antenna elements, wherein the first group of antenna elements and the third group of antenna elements are antenna units covering different geographical areas on the same site, or The first group of antenna elements and the third group of antenna elements are antenna elements within the same antenna combination.

The present invention utilizes the following transmit channel redundancy that exists in existing multi-antenna and/or multi-band systems:

(1) The transmit channel of the idle TDD system during the upstream time slot of the TDD system;

(2) The idleness of a portion of the transmission channel determined by the statistical difference in the channel matrix rank between the terminal reception channels or the terminal service demand during the downlink time slot of the TDD system or the frequency band used by the downlink channel of the FDD system.

These redundancy exists in the system in one or more of the following ways:

The first type of transmission channel redundancy - the same frequency point multi-carrier multi-antenna same cell (referring to the geographical area covered by multiple co-frequency carriers) the transmission channel redundancy existing in the system;

The second type of transmission channel redundancy - one multi-frequency point multi-carrier and the same coverage (refers to the same geographical area covered by multiple carriers, there are two or more carriers on each frequency point) the transmission existing in the multi-antenna system Channel redundancy;

The third type of transmission channel redundancy - the redundancy between multiple sectors on one site; the fourth type of transmission channel redundancy - the transmission channel redundancy existing in the TDD and FDD composite system: uplink in the TDD system In the time slot, the transmission channel configured for the TDD system is in a redundant/idle state; the fifth type of transmission channel is redundant. The transmission channel redundancy exists in the TDD system in which the uplink and downlink time slots are asynchronously arranged on the discontinuous TDD frequency band. : There is transmit channel redundancy on each TDD band. In various embodiments of the present invention, the configuration of the transmitting antenna unit and the receiving antenna unit unit covering the same cell is as follows:

In the antenna configuration mode 1, the same cell shares the transmitting antenna unit and the receiving antenna unit, and the manner of sharing the antenna unit is a common method of the existing cellular mobile communication system. For example, in the GSM system, the receiving channel and the transmitting channel share the antenna unit on the network side; in the TD-SCDMA system, the receiving channel and the transmitting channel on the network side also time-multiplex the antenna unit.

In the antenna configuration mode 2, the same cell transmits signals to the terminal and receives signals from the terminal to use different antenna units. This method is not applied in the existing cellular mobile communication system. However, in the manner of the time division multiplexed transmission channel described in the embodiment of the present invention, the following advantages can be obtained by using this method:

(1) Two separately installed antennas can increase the isolation of the network side transmission channel from the network side receiving channel;

(2) The circulator or duplexer under the traditional shared antenna structure is omitted, thereby reducing the system complexity and insertion loss, and improving the coverage of the cell.

Moreover, in the case of multi-band multi-system integrated networking, it is worthwhile to use different antenna units to transmit and receive signals, although it will increase the space occupied by the antenna unit installation, for example, in TDD system and FDD system coverage. In the same geographical area, according to the existing technology, the FDD system configures a set of antennas to cover a geographical area by means of transmitting and receiving shared antennas, and the TDD system also configures a set of antennas to cover the geographical area by means of transmitting and receiving shared antennas. In the area, a total of two antenna units are used, each of which is used in a shared manner. In the case where the transmitting and receiving antennas are separated in the embodiment of the present invention, the transmitting channel of the FDD system and the transmitting channel of the TDD system use the same set of antennas as the transmitting antenna of the covered geographical area, and the receiving channel of the FDD system and the receiving channel of the TDD system are used. The same set of antennas receive signals from the geographical area covered. In this way, it is convenient to configure the power of the transmitting channel in the TDD frequency band and the FDD frequency band, and reduce the out-of-band leakage power of the frequency band of the FDD transmitting channel to the TDD receiving frequency band, and the number of antennas is still two sets, and the TDD system and The same is true for the separate deployment of FDD systems.

In the case of antenna configuration mode 2, the transmit antenna uses a transmit filter and the receive antenna uses a receive filter. The transmit filter and the receive filter are different physical devices. In this filter configuration, the FDD band shares a transmit filter with the TDD band, compared to the TDD system and FDD. A filter is reduced when the system is deployed in a discrete manner.
