The technical field to which the invention relates

The present invention relates to a method and apparatus for transmitting/receiving messages in a wireless communication system and, more particularly, to a method and apparatus for transmitting/receiving messages alert the neighboring base stations, shirokanedai base station in the system broadband wireless access (BWA).

Prior art

Communication network of the fourth generation (4G), which are the next generation communication systems are designed to provide users with services having various quality of service (QoS)and support data transfer speeds up to 100 Mbit/S. In particular, in modern communication systems 4G are developing to support high-speed service by ensuring mobility and QoS in communication systems broadband wireless access, such as local (LAN) and urban (MAN) communication network. The exemplary communication system, currently under development, known as the communication system according to the IEEE (Institute of engineers in electronics and electrical engineering) 802.16 standard.

Compared to conventional wireless technology to provide voice services, the IEEE 802.16 communication system provides transmission of data over a shorter time interval than that required when using Oba the different communication technologies, by providing a wider bandwidth data and possibilities of effective use of data channels, by sharing all user data channels. In addition, the IEEE 802.16 communication system provides QoS, so that users can receive services with different quality of service, depending on the properties of services.

Among the communication systems of the IEEE 802.16 communication system, the IEEE 802.16a does not take into account the mobility of the terminal, while the IEEE 802.16e communication system considers mobility of the communication terminal (e.g. a mobile station).

For this reason, in the IEEE 802.16e communication system, the base station periodically broadcasts a message MOB_NBR-ADV (alert mobile stations about the neighbors), which contains information about the neighboring base stations, all mobile stations located in the corresponding cell, to support relay transmission maintenance mobile stations, thus informing mobile stations information about the state of the neighboring base stations. That is, when moving in a certain cell of the mobile station in the neighboring cell in relation to this mobile station can be performed relay transmission service, because the mobile station is already perceives information of the base station of the neighboring cell, such as the network ID and Hara the indices of the channels, siricoidea this base station.

The following table 1 shows the format of a regular message MOB_NBR-ADV used for communication base station, the mobile station information about neighboring base stations. These message formats are well known in the art, so their detailed description will be omitted for the sake of clarity.

Message MOB_NBR-ADV shown in table 4 additionally includes a reserved field the size of two bits to specify in bytes the length of a regular message MOB_NBR-ADV shown in table 1. In the message MOB_NBR-ADV according to the present invention has redefined flag field ID of the operator. Flag field ID of the operator used to indicate whether the message MOB_NBR-ADV ID field operator. For example, when the flag field of the operator ID is set to "1", this means that the message MOB_NBR-ADV does not contain the identity operator. In contrast, when the flag field of the operator ID is set to "0", the mobile station accesses a field of the operator ID.

Since the identifier field of the operator contains information about the network operator, while the mobile station uses the network of the same operator, periodic update identifier field operator is not necessary. Therefore, while the mobile station remains in the network of the same operator, the flag field of the operator ID is set to "1"and the field identificat the RA operator can be removed. The total message size MOB_NBR-ADV can be reduced by 3 bytes.

Below will be described the other fields in the message MOB_NBR-ADV shown in table 4.

Message MOB_NBR-ADV includes a Type field of the control message=53" size of 8 bits; the "Counter configuration changes for presentation, did a message by adding "1" whenever the configuration is changed; the "fragmentation Index" length 4 bits to represent the order passed at the moment of the message if the message MOB_NBR-ADV fragmented and therefore is passed through a set of message fragments, the Total fragmentation" length 4 bits to represent the total number of fragmented messages; and a one-bit field Flag skip optional fields". Additionally, the message MOB_NBR-ADV includes the "operator ID" length 24 bits, when the flag field of the operator ID is set to "0".

The other fields in the table 4, with the exception mentioned above refer to the length, the ID of the BS and relay the transfer of neighboring base stations, the fields are well known in the art, so their detailed description for the sake of clarity will be omitted.

The process for performing a relay transmission maintenance mobile station through the use described to enter the message MOB_NBR-ADV will be described in detail with reference to the accompanying drawings.

Figure 2 shows the block diagram of the sequence of operations illustrating the process of a relay transmission maintenance mobile station in the mobile communication system according to a variant implementation of the present invention.

In order to perform relay transmission service, the mobile station 10 before the relay transmission service should take the information about the neighbor base stations by receiving messages MOB_NBR-ADV from the first base station 21, which currently serves the mobile station. Thus, the first base station 21, carrying out communication with the mobile station 10, and transmits the message to the MOB_NBR-ADV according to a variant implementation of the present invention, as shown in table 4, in order to reduce repetitive transmission of information TLV messages about the neighboring base stations.

Then, as shown in figure 2, at step 201, the mobile station 10 receives a message MOB_NBR-ADV from the first base station 21.

At step 202, the mobile station 10 checks the flag field of the operator ID from the message MOB_NBR-ADV, received from the first base station 21. In the result of the determination, if the flag field of the operator ID is set to "0", then the mobile station 10 updates the value of the ID of the operator at step 203, and then proceeds to step 204.

Otherwise, if at step 20 is defined, that flag field ID of the operator is set to "1", then the mobile station 10 directly goes to step 204. At step 204, the mobile station 10 performs scanning on the subject base station 22, which moves the mobile station 10, and then performs the process of a relay transmission service at step 205.

Meanwhile, the message MOB_NBR-ADV arranged to reduce repetitive information transfer TLV messages about neighboring base stations will be described with reference to table 4.

Message MOB_NBR-ADV field contains "operator ID" length of 3 bytes and field neighbor BS_ID" length of 3 bytes. When this BS ID field length is 6 bytes included in DCD_settings, formed by the unification of the 3-byte identifier of the operator and 3-byte neighbor BS_ID. Therefore, when the message MOB_NBR-ADV contains the operator ID and DS_ID neighbor, then a 6-byte identifier field BS message DCD_settings can be omitted.

According to the prior art, since the information TLV messages MOB_NBR-ADV must repeatedly be transmitted to all neighboring base stations, the intensity of service signaling was increased in proportion to the number of re-transmitted 6-byte identifiers BS field DCD_settings. In this case the ID field BS information TLV messages DCD_settings has a size of 6 bytes and includes 1 byte type 1 byte length, so the total size to represent the ID of the BS is equal to 8 bytes. However, according to a variant implementation of the present invention identifier field BS excluded from the format DCD_settings, thereby reducing the service signaling "R", as described below in equation 1

R=N×8 bytesEquation 1

That is, when the base station broadcasts a mobile station message with information about the neighboring base stations for 10 neighboring base stations, then lowering the BS ID included in the message DCD_setting, service alarms can be reduced to (N×8 bytes=10×8 bytes 80 bytes.

As described above, according to the present invention, when the base station sends the mobile station a message with the information about the neighbor base stations in the system, broadband wireless access, omitted information, or are not required to repeat the transmission of each message, or transmitted repeatedly, and flag field is added, so that it becomes possible to reduce the service signaling and to improve the transmission efficiency.

SUBSTANCE: invention refers to identification of transmitters for signals received by terminal. In order to evaluate transmitter of this received signal, candidate list of transmitters which could transmit this signal is made out. Besides coverage area is detected to be used for received signal. This coverage area is area where terminal can receive signal to be identified. Then predicted power for each candidate transmitter is evaluated, e.g. using route and coverage area loss prediction model. Predicted powers for candidate transmitters are compared (directly or relatively) to measured power of received signal. Candidate transmitter with (direct/relative) predicted power closest to (direct/relative) measured power is considered to be that one transmitted this signal. Distribution delays can be predicted and used for transmitter identification as well.

EFFECT: estimation of terminal location.

SUBSTANCE: invention refers to data transmission in wireless communication system with multiple-key access. Wireless communication terminal scans pilot signals transmitted by sectors in wireless communication system, measures scanned pilot signals, selects serving sector (e.g. sector providing the strongest reception) and identifies nonservicing sectors which can receive strong noise from this terminal. Servicing sector allocates terminal sub-band (sub-bands) which can be used by servicing sector and cannot be used by nonservicing sectors. Terminal transmits data symbols to allocated sub-bands to servicing and nonservicing sectors. These sectors process return communication line transmission from terminal and receive symbols of relaxed solution which represent transmitted data estimations. Symbols of relaxed solution can be combined from common sectors and then decoded to receive decoded packages. Sectors can decode symbols of relaxed solution independently, and decoded packages of these sectors can be combined to receive resultant decoded packages for terminal.

EFFECT: development of relaxed service forwarding for return communication line with restrictive reuse.
