The technical field to which the invention relates

This invention relates to the field of radio communications and, in particular, to a method of aggregation of the carrier frequencies and corresponding base station, mobile terminal, and the aggregation system carrier frequencies.

Background of the invention

As another advanced standard "Long-term development of communication networks" - Long Term Evolution (LTE), also known as LTE-Advanced (LTE-A), was used many new technologies, including technology of aggregation of the carrier frequencies as the underlying technology to support communication in a broadband range. The basic principle of aggregation of the carrier frequencies is that is the aggregation of two or more carrier frequencies to meet the needs of the range with a broader bandwidth. With the introduction of aggregation of the carrier frequencies, the number of working carrier frequencies in the cell was increased from one to several, and the result was the ability to communicate on multiple carrier frequencies. According to 3GPP RAN1#57bis, these carrier frequencies are divided into the following three categories.

1. Backward-compatible carrier frequency: the carrier frequency is available for the terminal LTE R8 and the terminal LTE-A and may be one of the aggregated carrier frequencies for the terminal LTE-A.

2. The carrier frequency specifically �La LTE-A: this carrier frequency is not available for the terminal LTE R8, but available for the terminal LTE-A and can be one of the aggregated carrier frequencies for the terminal LTE-A.

3. Auxiliary carrier frequency: the carrier frequency is not available for the terminal LTE R8 and available for the terminal LTE-A, it is of particular conditions of access, namely, when communication is established with the terminal via a backward-compatible carrier frequency or special carrier frequency for LTE-A and the auxiliary carrier frequency can be used as an additional carrier frequency during aggregation of carrier frequencies for a given terminal. That is, the auxiliary carrier frequency can only be used with the terminal for which the connection was established via two or more carrier frequencies, but not the carrier frequency, working with the terminal for which the connection is established only on one carrier frequency.

Currently LTE-A is divided into two modes of operation:

duplex communication with time division (TDD) and duplex communication with the channel frequency division (FDD). Accordingly, the mobile terminal operating in the TDD mode, referred to as a TDD terminal, a mobile terminal operating in the FDD mode, referred to as FDD terminal. The carrier frequency used in the TDD mode, referred to as TDD carrier frequency and the carrier frequency used in FDD mode, referred to as FDD carrier frequency.

IP�odya from the prior art up to the present time did not exist any complete solutions for the aggregation of the carrier frequencies. Although the idea of aggregation of the carrier frequencies for TDD TDD terminal and aggregation of carrier frequencies for FDD FDD terminal had previously expressed, but no specific decisions on their implementation was proposed. In addition, it should be said that, aggregation of carrier frequencies, covering different modes, namely: aggregation of the carrier frequency FDD TDD terminal and aggregation of the carrier frequency TDD FDD terminal is impossible.

A brief summary of the invention

Embodiments of the invention provide for a method of aggregation of the carrier frequencies and corresponding base station, mobile terminal and aggregation system carrier frequencies, so that the terminal TDD and FDD terminal could be aggregated carrier frequency TDD and FDD carrier frequency.

Variant implementation of the invention provides a method of aggregation of the carrier frequencies, including:

getting through the connected mobile terminal information about how to manage the aggregation of the carrier frequencies transmitted from the base station, where the information about how to manage the aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio carrier frequency of the receiver; and

determining, using a mobile terminal, the carrier frequency �the receiver in accordance with the identifier of the carrier frequency and information about the configuration of the radio installation.

Variant implementation of the invention provides, furthermore, a base station, including:

functional block aggregation of carrier frequencies, configured to transmit information about the management of aggregation of the carrier frequencies on the connected mobile terminal, where the information about how to manage the aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio carrier frequency of the receiver.

Variant implementation of the invention also provides a mobile terminal including a device providing connection configured for connection with the base station where the mobile terminal includes:

receiving unit, configured to obtain information about how to manage the aggregation of the carrier frequencies transmitted from the base station, where the information about how to manage the aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio carrier frequency of the receiver; and

the unit of aggregation of the carrier frequencies, configured to determine the carrier frequency of the receiver in accordance with the identifier carried�ing frequency and information about the configuration of the radio installation.

Variant implementation of the invention also provides for the aggregation system carrier frequencies, including base station and mobile terminal, where the base station is configured to transmit information about the management of aggregation of the carrier frequencies on the connected mobile terminal, where the information about how to manage the aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio carrier frequency of the receiver; and

a mobile terminal configured to obtain information about how to manage the aggregation of the carrier frequencies transmitted from the base station, and to determine the carrier frequency of the receiver in accordance with the identifier of the carrier frequency and information about the configuration of the radio installation.

With the help of this invention, the base station transmits information about the management of aggregation of the carrier frequencies to the mobile terminal (mobile terminal can be used TDD terminal or terminal FDD), where information about the management of aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio receiver. The mobile terminal determines not�painful on the receiver frequency (the carrier frequency of the receiver can be the carrier frequency TDD or FDD carrier frequency; in this case the carrier frequency of the receiver transmits the data to its operating mode regardless of whether the carrier frequency TDD or FDD carrier frequency) in accordance with the identifier of the carrier frequency and information about the configuration of the radio installation. If you use the above method does not need to recognize the mode of operation of the carrier frequency of the receiver (i.e. whether the carrier frequency of the receiver carrier frequency TDD or FDD carrier frequency), as well as to recognize the operating mode of the mobile terminal (i.e. whether the mobile terminal terminal TDD or FDD terminal), and the aggregation of the carrier frequency in the same mode or in different modes is fairly straightforward.

Detailed description of embodiments of the invention

Variant implementation of the invention provides a method of aggregation of carrier frequencies in such a way that the terminal TDD and FDD terminal can aggregate and carrier frequency TDD Inessa frequency FDD.

Method of aggregation of carrier frequencies in accordance with an embodiment of the invention will be described in detail below with reference to the drawings.

Fig.1 provides a graphic representation of the method of aggregation of carrier frequencies in accordance with an embodiment of the invention, which includes the following steps.

Step S101. The connected mobile terminal receives information about the management of aggregation of the carrier frequencies transmitted from the base station.

Information about how to manage the aggregation of carrier frequencies includes the identifier of the carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel and the configuration information of radio carrier frequency of the receiver.

Step S102. The mobile terminal determines the carrier frequency of the receiver in accordance with the received identifier of the receiver and information about the configuration of radios and monitors the downward control channel of the carrier frequency of the receiver.

Step S103. The mobile terminal performs the analysis for information about the management of a descending channel of temporary radio network identifier (C-RNTI) for a mobile terminal that is carried by the downward control channel of the receiver.

Step S104. The mobile terminal receives the data of the descending channel transmitted from a base of one hundred�tion to the mobile terminal in a top-down multiplex channel in accordance with the received information on the management of a descending channel C-RNTI.

The above steps will be described in detail below.

The mobile terminal LTE-A establishes a connection to the radio controller (RRC) with base station for communication to the implementation of step S101. In particular, for communication TDD terminal is connected to a carrier frequency TDD and FDD terminal connects to the FDD carrier frequency. Base station (eNB) configures the mobile terminal to work with the aggregation of carrier frequencies using the transmission management information of the aggregation of the carrier frequencies to the mobile terminal in order to add a mobile terminal, the working carrier frequency through its aggregation and to the newly added working carrier frequency could be downward carrier frequency FDD or descending TDD carrier frequency. In step S101, the mobile terminal receives information about the management of aggregation of the carrier frequencies transmitted from the base station, which includes the identifier of the carrier frequency of the receiver for aggregation as a downlink operating carrier frequency and the configuration information of radio carrier frequency of the receiver. In certain embodiments, the application identifier of the carrier frequency of the receiver and information about the configuration of the radio carrier frequency of the receiver can be transmitted to the mobile terminal in various ways.

Example�, when the identifier of the carrier frequency of the receiver and information about the configuration of the radio carrier frequency of the receiver is transmitted at the level of the signal RRC, corresponding control signals are determined by the format of the RRC control signals in accordance with 3GPP 36.331, and may include data such as the frequency, bandwidth range, the configuration of the indicator channel (PHICH) hybrid automatic request for retransmission (HARQ), the block number of the system (which may be absent if the carrier frequency of the receiver is synchronized with the current working channel of the carrier frequency of the mobile terminal), the boundaries of the start of the monitoring (which may not exist, if the designated interval of control accepted) and information about the configuration of the radio carrier frequency of the receiver. In another example, the RRC control signals may include a number, the boundary of the monitoring and configuration information radio carrier frequency of the receiver. The configuration of the radio installation includes configuration of the downward multiplexed channel, the configuration of the upward control channel, the configuration of the upward multiplexed channel, the power control of the upward signal, the configuration of the feedback report on the state of the channel, the configuration status of the antenna. Description�, the above is given only as an example, it should be noted that the identifier of the carrier frequency of the receiver and information about the configuration of the radio carrier frequency of the receiver can be transmitted in a different format signal and the invention is not restricted to these limits.

In addition, the eNB will program the operation of the mobile terminal on the basis of the carrier frequency of the receiver (carrier frequency FDD or TDD downward channel) within a certain time period after transmitting the management information aggregation of the carrier frequencies to the mobile terminal. That is a temporary identifier of a system information radio network (SI-RNTI), a temporary identifier of the paging radio network (P-RNTI) and the temporary identifier of the mobile radio network (C-RNTI) for a mobile terminal is transmitted via the downward control channel of the carrier frequency of the receiver. The carrier frequency of the receiver for aggregation as a working carrier frequency of the descending channel any can't be changed, but can ensure the transmission of relevant data in its own operating mode and in accordance with the programming eNB. That is, when the carrier frequency FDD accepted as the carrier frequency of the receiver, is applied to the carrier frequency for FDD aggregation as a working carrier frequency of the downtrend channel there is no ODA�gelendost in terms of whether the corresponding data for transmission over a carrier frequency intended for transmission to the terminal TDD or FDD terminal; similarly, when the carrier frequency TDD is adopted as the carrier frequency of the receiver, is applied to the carrier frequency for TDD aggregation as a working carrier frequency of the downward channel is not clear whether the corresponding data for transmission on a carrier frequency transmitted to the terminal TDD or FDD terminal.

The mobile terminal determines the carrier frequency of the receiver in accordance with the received identifier of the receiver and information about the configuration of radios and monitors the downward control channel of the carrier frequency of the receiver in step S102.

The mobile terminal can monitor the following two ways.

The first method provides an explicit indicator: information about the management of aggregation of the carrier frequencies transmitted from the base station to the mobile terminal, includes the start of the monitoring indicator, the mobile terminal initiates the monitoring of the downward control channel of the carrier frequency of the receiver by determining the time to begin monitoring in accordance with the received indicator of the start of the monitoring. The light of the monitor can show the monitoring interval, namely to instruct mo�ilen terminal to begin monitoring after a period of time, equal to X milliseconds, from the moment of receiving information about how to manage the aggregation of carrier frequencies, or may show the boundary of monitoring, namely to instruct the mobile terminal to begin monitoring of the downward control channel of the carrier frequency of the receiver at the appropriate time within the boundaries of the beginning of the monitoring period.

The second method is implicitly expressed by the indicator: monitoring interval is assigned in advance by agreement between the base station and the mobile terminal. The mobile terminal initiates the monitoring of the downward control channel of the carrier frequency of the receiver based on the definition of the end of the monitoring interval agreed upon in advance with the base station, after receiving the management information aggregation, transmitted from the base station.

The mobile terminal performs the analysis to obtain the control information of the descending channel C-RNTI for the mobile terminal, which is carried by the downward control channel of the carrier frequency of the receiver, in step S103. With respect to the control information of the descending channel SI-RNTI and P-RNTI analysis is not performed. Thus, you can ensure that the mobile terminal will use the carrier frequency of the receiver as an auxiliary carrier frequency.

The mobile terminal receives the data downward to�Nala, transmitted from the base station to the mobile terminal in a top-down multiplex channel in accordance with the received control information of the descending channel C-RNTI in step S104.

In the method of aggregation of carrier frequencies in accordance with a variant implementation of the invention described above, when information about the configuration of the radio carrier frequency of the receiver is changed, the base station will transmit to the mobile terminal the information about the changed configuration of the radio communication means, so that the mobile terminal can receive the data in the usual way when the modified configuration radio. Information about the changed configuration of the radio carrier frequency of the receiver can also be transmitted to the mobile terminal using RRC control signals.

When the mobile terminal needs to leave the carrier frequency of the receiver, the base station will simply pass the output indicator of the aggregated carrier frequency, passing the identifier of the carrier frequency to the mobile terminal, and an output indicator of the aggregated carrier frequency may also be transmitted to the system control signals RRC or other means for transmitting to the mobile terminal. The mobile terminal stops monitoring the downward control channel of the carrier frequency of the receiver on the basis of getting� indicator on the output of the aggregated carrier frequency from the base station.

SUBSTANCE: description is given of a method and device for switching wireless terminal channels. For this, several communication channels with different physical characteristics are supported in the cell of the base station. Each wireless terminal controls several channels and evaluates several channels at the same time, such that, there can be fast switching between channels. Information on the quality of the channel is sent from each wireless terminal to the base station. The wireless terminal or base station selects the channel, based on the evaluated quality of the channel. By supporting several channels and through periodical changes in channels in different implementation alternatives, the time taken before the wireless terminal finds good or suitable channel conditions is minimised, even if the wireless terminal changes position. Several antennae are used at the base station for simultaneous support of several channels, for example, through control of the directional pattern of the antennae.

EFFECT: reduced delays before wireless terminal finds suitable channel conditions.
