Abstract

In a wireless communication system, (e.g., a wireless local area network (WLAN)), including a plurality of wireless transmit/receive units (WTRUs) and a coordinating node, (e.g., an access point (AP)), path loss is estimated by transmitting a loud packet from a first one of the WTRUs to a second one of the WTRUs. The coordinating node transmits a loud packet generation request message. A first one of the WTRUs receives the loud packet generation request message and transmits at least one loud packet at a transmission power specified by the loud packet generation request message. Optionally, the first WTRU transmits a loud packet generation response message. A second one of the WTRUs receives the loud packet and determines a path loss between the first WTRU and the second WTRU by subtracting the signal strength of the loud packet from the determined transmission power of the loud packet.

Description

Produce the method and the device of loud package estimation path loss
Technical field
The invention relates to a kind of wireless communication system (for example: a kind of radio area network (WLAN)), its comprise a plurality of wireless transmission/receive units (WTRUs) (that is: mobile platform).The present invention especially about a kind of in order to produce loud package (loud packets) with the method and the device of path loss between estimation WTRUs.
Background technology
In a kind of its multiple access mechanism is to avoid in the wireless system of (CSMA/CA) according to the carrier sense access/collision of IEEE 802 standards (for example: IEEE 802.11), WTRUs can use the WTRUs of same channel to transmit the signal strength signal intensity of coming according to being received from vicinity, decides and when attempts receiving and the transmission package.By avoiding transmission manner simultaneously, a plurality of WTRUs just can avoid interfering with each other when sharing identical channel.
The parameter that some are crucial, similarly be energy measuring threshold value (EDT) and postponement threshold value (DT), typically use by WTRU, when it can transmit or receive a package with decision, EDT is the minimum received signal power that expression attempts receiving a package, DT then represents minimum received signal power that package will be postponed of this WTRU transmission, and the DT value can or can be not identical with the EDT value.
Although the basic concept of CSMA/CA is very clear and definite, for heap(ed) capacity, still there is some situation can cause the excessive reduction of capacity, for instance, two transmitters (communicating by letter with different receivers) can transmit simultaneously and not have apparent the situation that interferes with each other, but because its value that listens to each other is higher than other EDT and/or DT, therefore they can not transmit, this will cause the waste of capacity, if and each generation in the following action, these wastes are avoidable:
A) this WTRUs reduces its through-put power, makes this WTRUs to monitor and surpasses this EDT and/or DT mutually, but still can communicate by letter by best other corresponding intrument of data transfer rate and its;
B) this WTRUs improves its EDT and/or DT, makes the signal that receives from the other side can be lower than its threshold value; Or
C) in conjunction with a) and b).
This will be called the postponement management by the technology that above-mentioned parameter (through-put power, EDT, DT) judged and be provided with in node or system hereinafter at this.If WTRUs knows each other path loss and employed EDT of other WTRUs or DT value, then suitable is provided with these parameters with helpful, these information will make WTRU (or other nodes, similarly be the access point (AP) of this some parameter of WTRU of control) measurablely whether can cause received signal to be higher or lower than the EDT value of a given contiguous WTRU with specific grade transmission, this information will can be used for helping in the algorithm of optimization capacity afterwards.
The estimation of obtaining path loss also can be used for the aspect, location.Use WTRUs between the path loss setting, the position of WTRU just can be estimated in and several fixedly WTRUs (typically being APs) or location of grid point (MPs in mesh network).This estimation can be carried out by node (it may be or may not be WTRU), collects from the path loss estimation of one or more different WTRUs.
Therefore, just need a kind of WTRU can estimate positively that it arrives the method for the path loss of other WTRUs.
Problem to be solved
A kind of clear and definite mode that reaches the path loss between two WTRU adjacent in order to estimation between a WTRU with a WTRU, be to deduct received power by the perception of the employed through-put power of the 2nd WTRU institute with a WTRU, this is that hypothesis the one WTRU decidable the 2nd WTRU transmits the measured signal power of a WTRU, and following is the factor that can't reach under the WTRU technology of the current state for where:
1) in being provided with of the through-put power of APs, the WTRUs in this field and MPs, WLANs is the owner and does not communicate by letter with other WTRUs, for instance, existing 802.11h/802.11k through-put power control (TPC) mechanism is only forced the maximum transmission power setting of basic service set (BSS), and it also can't exceed this value for the purpose of adjusting.It must be appreciated that any WTRU can change this through-put power under the maximum of forcing restriction, and does not need to communicate by letter with the through-put power of decision to other WTRUs, APs or MPs with its inner owner.
2) whenever the employed through-put power of this WTRU can change on packet basis.This point is meaning, and in order to allow a WTRU estimate the path loss of the 2nd WTRU that separates with it, a WTRU need receive the package from the 2nd WTRU, and by this, the power that transmits this package will be indicated in this package.In above-mentioned example, allowing similarly is that the signal of transmission of this type of package sends, and the TPC request/TPC report frame switch system of 802.11h/802.11k is only arranged, and it needs the two-way signaling of a special use to send to exchange and can't periodically be provided with.In addition, this TPC request/report can't be sent to the WTRUs that is positioned at the BSS outside.Adjusting its through-put power and DT/EDT parameter in the purpose of WTRUs, making it can increase the capacity of this system and do not need in the BSSs of system, to produce under the situation of a concealed nodes, just needing to obtain path loss between the WTRUs from a different WTRU.
3) in many cases, the one WTRU may and not hear the 2nd WTRU, this is because the 2nd WTRU a power delivery also lower than maximum power, if the 2nd WTRU uses the battery management technology or postpones under the administrative skill, just this situation might take place.Be to adjust under its situation of postponing management parameters in a WTRU purpose, must be noted that the path loss that may need to estimate WTRUs, even if it can't monitor them.Now without any mode can allow a WTRU node order to another WLAN node with increase its through-put power or even directly manage the use of specific transmission power, rather than use the maximum power of defined.This also can be applicable to TPC request/TPC report mentioned above.
Above-mentioned mentioned problem (or lacking this mechanism) about mechanism, just can illustrate that the path loss estimation between WTRUs causes some problems really, in some example, this mechanism forces the transmission power value of a contiguous WTRU of WTRUs hypothesis, under the difference of different WTRU manufacturers, this is not very accurate, and might be close to WTRU and use and to be lower than peaked through-put power.In other examples, this mechanism can prevent fully that two path estimations between the WTRUs from taking place.
Summary of the invention
The present invention lies in wireless communication system, and (for example: implement WLAN), it (for example: access point (AP)) comprises a plurality of WTRus and a coordinator node.By one two WTRU of loud package of one the one WTRU among this WTRUs transmission to this WTRUs.Loud package of this coordinator node transmission produces solicited message.The WTRU of this WTRUs receives and should produce the information that requires by loud package, and by this loud package produce require information transfer to a loud package less on the specific through-put power.Optionally, WTRU transmission one loud package produces reaction information.The 2nd WTRU of this WTRUs receive this loud package and determine a WTRU and the 2nd WTRU between path loss, it is determined by the signal strength signal intensity that deducts this loud package with the through-put power that this loud package was determined.

Hereinafter, WTRU can be considered any at wireless communication system (for example: IEEE 802 wlan systems), any node in a platform (AP or non-AP), an independent based services set (IBSS) or the basic structure basic service set (BSS), or the grid point in a mesh network, grid AP or grid inlet.
Feature of the present invention can be integrated in the integrated circuit (IC), or is configured in the circuit that comprises many interconnection elements.
The notion of loud package
According to one embodiment of the invention, WTRUs according to the time on a large transmission power, transmit package, (after this be considered as " loud package "), by this, this package transmission performance number just can be known by other WTRUs.These loud packages do not need to deliver to any specific WTRU or WTRUs group, and can merely be broadcast to the one group of WTRUs that receives on same frequency channel.Needs calculate the contiguous WTRU of the path loss estimation of the WTRU that transmits loud package, and the loud package signal strength signal intensity by being received is compared and learnt with the through-put power that this loud package is indicated or known easily.For instance, this path loss estimation can obtain by using following equation:
Signal strength signal intensity intensity (dBm) equation (1) of the loud package that the through-put power (dBm) of path loss (dB)=loud package is received
Preferably, the information field middle finger that lies in this loud package of the through-put power of this loud package shows.Perhaps, this through-put power also can be periodically by AP broadcasting, with every this WTRU of indication immediately after this AP links to each other, or show that the some that exchanges as other signal transmissions is sent to WTRU.In this case, praise loyalty in loud envelope and have an information field so that inform reception WTRU its be a loud package and do not show a general package.Preferably, the through-put power of this loud package should equal to transmit the maximum transmission power of the WTRU of this loud package, and this can guarantee the successful reception of the maximum possible scope of this loud package, and the most reliable estimation, yet this is dispensable.Other packages of it should be noted that non-loud package can transmit on a lower power, so that the parameter of balance other system.
A recognin that transmits the WTRU of this loud package (for example: MAC Address) also should be included in the information field, so that the WTRUs that receives knows which the pairing WTRU of this path loss is.
Perhaps, loud package can be implemented by any existing signal transmit frame, and it is being sent by the selected through-put power of this transmitter, and this through-put power is also by known to this receiver.For instance, this through-put power can be additional or be equipped on known to the message elements (IE) in the existing signal transmit frame via one by this receiver.Perhaps, this loud package know through-put power also can be used as previous and this loud package the sender handshaking some and by known to this receiver.
On the advantage of implementing, system uses beacon/probe reaction frame as loud package, and its other through-put power can be this beacon/probe request frame itself, or the through-put power setting agreed in advance of these frames, it is to communicate by letter with this WTRUs by other devices, similarly is that the neighbor information signal sends.
The extraneous information of in loud package, reporting
Loud package can be used as a kind of elasticity report mechanism, to help to receive WTRUs its parameter of optimization (through-put power, EDT, DT), following parameter can (be known through-put power except this WTRU recognin reaches this loud package by this transmission WTRU (sender) report, or if necessary, as the signal transmission of unit):
1) in the BSS of a basic structure, this AP is connected to address or the recognin (and/or this BSS, IBSS or grid recognin) of this WTRU.
2) be used to transmit the power of the package of non-loud package.
3) by this sender examined know and other WTRUs between the path loss estimating table.
4) this sender is received from package signal strength signal intensity (or average signal strength) table (value of this WTRU whenever) of other WTRUs.
5) sender is received from the package total duration table (value of this WTRU whenever) of other WTRUs in the time of a specified quantitative.
6) use by this sender, or this sender is known EDT about other WTRUs.
7) use by this sender, or the known idle assessment of channel (CCA) about other WTRUs of this sender.
8) use transmitting a package by this sender, or this sender is known DT about other WTRUs.
Carry and select
For the signal that limits its use sends the amount of frequency range, a loud package can carry on other forms of package and (comprise flow control or management information).In this case, preferably, whole package should transmit on the power of this loud package.
The coordinated management of loud package transmission
Transmit loud package and do not need not to be restricted in specific WTRUs and just can carry out, yet, may need this transmission can be controlled at during some extends by a coordinator node.Typically, this AP should play the part of the role of coordinator node in a foundation structure BSS.Control the generation of loud package by a coordinator node, will have the advantage that guarantees minimum usefulness, it is to look closely in this system employed specific postponement administrative skill or location technology and decide.
Figure 1 shows that a signal flow cardon, wherein, this loud package system transfers to one or more WTRUs 1101-110N in a wireless communication system 100 by a coordinator node 105, and it is to dispose according to the present invention.The management of loud package transmission can use that (for example: an AP) one or more WTRUs 110 that sends a signal to the defeated loud package of tendency to develop is reached by this coordinator node 105.This type of signal sends and can implement by following manner, at first, produces solicited message 115 to this WTRU (s) 110 by this coordinator node 105 transmission one loud package.Then, this loud package produces solicited message 115 and (for example: all WTRUs of this BSS), or single broadcasting information can be broadcast to all WTRUs 110 under the control of this coordinator node 105.This loud package produces solicited message 115 and also can append, and for instance, wherein a kind of existing IEEE 802 signals send exchange, similarly is about in the association/authentication or the frame of approval control program.
Be included in this loud package and produce information in solicited message 115, mean show following one of them or more than:
1) is used for the through-put power of this loud package.
2) information (in above-listed all possible fields) of desire report in loud package.
3) transmit the sequential of one or more loud package, several selections are arranged, it is to comprise but be not limited to:
I) periodicity or half period property ground is at a specific period that transmits continuously between the loud package.
Ii) the sequential of a specific quantity in a special time window (for example: one).
Iii) meeting a particular condition (triggering) afterwards, for example:
A) by a new WTRU transmission preamble detection: or
B) in a specific period, the quantity that package transmits again surpasses a particular threshold.
4) package that is received in a specific period again the quantity of transmission surpass a particular threshold.
5) whether this loud package of indication should carry (or not answering) on other packages.
6) about by the information of the loud package that other WTRUs produced (that is: above-mentioned all WTRUs except non-reception WTRU).
Receive this WTRU (s) that this loud package produces solicited message 115, optionally react a loud package and produce reaction information 120, as shown in Figure 1.This loud package produces reaction information and can indicate this WTRU will be in order to the through-put power of transmitting this loud package (if do not specify in this solicited message, if or be different from ask), if the through-put power of this loud package is not indicated in this loud package, this is very useful.In one embodiment, a loud package request of producing can be indicated in a field of a loud package, and therefore, this loud package produces solicited message and can be used by a WTRU, to estimate its path loss to other WTRU.
The non-coordinated management of loud package transmission
The another kind of mode that above-mentioned coordinated management mode is different is that WTRUs can spontaneously determine when to transmit loud package and must report which kind of information therein.This behavior can be agreed in advance by the WTRUs that follows a specific criteria.
Another mode is, allows any WTRU (being not only coordinator node) to send a loud package generation solicited message to other WTRUs, and this kind mechanism may be applicable to point-to-point and network.
Support the wisdom antenna
Above-mentioned system is applicable to the WTRUs that uses simple antenna, and for the WTRUs that supports to equip the wisdom antenna (that is: multiple wave beam or switched beam antenna), comprising some extra information in loud package is of great use:
1) the employed antenna beam of WTRU of the defeated loud package of tendency to develop, (this can produce in the solicited message in the loud package of this coordinator node and specify).Path loss between one the one WTRU and one the 2nd WTRU is looked closely employed antenna beam, can use different antenna beams if transmit this WTRU of this loud package, then this reception WTRU just will be appreciated which is in order to the antenna beam that transmits this loud package so that its know this path loss measure will with what antenna beam associated.
2) the employed antenna beam of WTRU of the package of the defeated non-loud package of tendency to develop.High postponement management algorithm must be known this information, so that the suitable parameter that this reception WTRUs is set (for example: postpone threshold value).
3) desire receives the employed antenna beam of WTRU of package.This is that the WTRU institute of this loud package of transmission is in order to the antenna beam of reception rather than receive the WTRU of this loud package, therefore, the WTRU that transmits this loud package notifies other WTRUs, no matter when it receives a package, it may use and the different particular antenna beam of antenna beam that is used to transmit this loud package at present.This information is quite useful to other WTRUs, whether makes them know again according to transmitting the postponement that can cause on this WTRU on the certain power.
Figure 2 shows that wireless communication system 200 calcspars that comprise a plurality of WTRUs 2051,2052, it is to use 222,242 transmission of wisdom antenna respectively and receive loud package, and it is according to the present invention.This WTRU 2051 comprises a processor 210, a transmitter 215 and a receiver 220, and this WTRU 2052 comprises a processor 225, a transmitter 230 and a receiver 235.
