Detailed description of the invention

Embodiments of which are disclosed in the present description relate to methods and devices for grouping the pilot signals and the use of such a grouping for a message about the level of the pilot signal and to control the sets in the communication system with multiple carriers.

Fig. 1 illustrates a variant of the implementation of the system 100 for various carriers. For example, within the system can be allocated to the various access terminals (at) 110, including at 110A-110S. Each terminal of the at 110 may communicate with network 120 access (AN) via one or more channels at different frequencies in a straight line and/or return line connection in a given time, as shown by bidirectional arrows 130. For illustration and clarity for each terminal at 110 shows two bi-directional arrow 130. You can have any number of channels (or frequencies) in a straight line tie is, and reverse lines of communication in the communication system. In addition, the number of frequencies used in a straight line (or "frequency straight line), is not necessarily the same as the number of frequencies in the return line (or frequency reverse line).

Network'AN 120 may optionally communicate with a base network, such as network packet data, via the service node 140 packet data (PDSN). In one embodiment, the system 100 can be configured to support one or more standards, for example, IS-95, cdma2000, IS-856, W-CDMA, TD-SCDMA, and other communications standards, with many bearing or combinations thereof.

As described herein, the network AN may refer to a part of a communication system configured to communicate with the core network (e.g., network packet data through a network PDSN 140 in Fig. 1) and routing data between terminals al and core network, perform the various functions of radio access and maintain lines of communication, management of radio transmitters and receivers, etc. Network AN may include and/or implement the functions of the base station controller (BSC) (as in a wireless network, the 2nd and 3rd generations), receiving and transmitting system of the base station (BTS), access point (AP), transceiver pool of modems (MRI), node (for example, in the system such as W-CDMA), etc.

Terminal antibodies described in the present is m document can refer to various types of devices including (not limited to) wired telephone, wireless telephone, cellular telephone, portable computer, map a personal computer (PC) wireless personal digital assistant (PDA), an external or internal modem, etc. Terminal antibody may be any data device that communicates through a wireless channel or through a wired channel (e.g., via fiber optic or coaxial cables). Terminal UT may have different names, for example, block access, subscriber unit, mobile station, mobile device, mobile unit, mobile phone, mobile device, remote station, remote terminal, remote unit, user device, user equipment, handheld device, etc. Various terminals at can be included in the system. Terminals at can be mobile or stationary and can be distributed over the communication system. The terminal at may communicate with one or more networks'AN in a straight line and/or return line connection at any given moment. Direct link (or downward link) refers to transmission from the network AN to the terminal at. The reverse link (or bottom-up communication link) refers to transmission from the terminal at the network'AN.

Communication system with multiple carrier described in this application may contain a system multiplexing frequency division, or system multiplexing orthogonal frequency division, or other systems, frequency modulation, and each carrier corresponds to a certain frequency range.

The pilot signal described herein, may be defined (or defined) by a pair of parameters and marked as <shift PN, channel>, where the parameter "channel" refers to the frequency of the pilot signal, and the offset PN" uniquely associated with the pilot signal. The term "channel" may be interchangeably used with the term "frequency". In addition, the "area coverage" the pilot signal may relate to the profile of the dependence of the signal on the distance to the pilot signal.

A cell can refer to a coverage area serviced by the network AN. The cell may be divided into one or more sectors. One or more frequencies may be assigned to cover the cells. In Fig. 2 shows a variant implementation of the cell 200 in the communication system with multiple carriers. For example, the cell 200 is shown as divided into three sectors 210, 220, 230. Three frequency f1f2f3assigned to cover the cell 200. For illustration and clarity, the cell 200 is shown as a cylinder of square cross section which correspond to the coverage area of the cell 200, and the height of the axis 240 corresponds to the dimension of the frequency of the cell 200. As such, each sector of a cylinder (for all frequencies) forms a sector of a cell. In other embodiments, implementation of the cells can have different shapes and can have a different number of sectors. Also there may be any number of frequencies assigned to a cell. For example, in some situations, multiple frequencies can be assigned to the cell, covering a large area of coverage, as shown in Fig. 2. In other situations, one frequency can be allocated to the cell, covering a small area with a high density (for example, a "hot spot").

In the communication system with a single carrier you want the terminal at reported levels of received pilot signals, since the pilot signals become strong or weak level. In the communication system with multiple carrier there are many pilot signals associated with the sector, as shown in Fig. 2. If the terminal antibody was required to inform about the level of each received pilot signal (as in a system with a single carrier), it would have caused too many runs for message-level signal (for example, the update message route in the system such as IS-856), because there are a lot of pilot signals, and each of them can independently cross the thresholds set for the transmission of messages, due to the short-term fading, and every of the message would be more because there are more pilot signals for the message. In addition, many of these pilot signals may have comparable coverage area and the message is passed to one of them, can provide enough information for the access network with respect to the set of pilot signals which are received by the terminal at. There is therefore a need for an effective method of control pilot signals in a communication system with multiple carriers.

Disclosed embodiments of relate to methods and systems for grouping the pilot signals and the use of such a grouping for a message about the level of the pilot signal and the control sets in the communication system with multiple carriers.

In one embodiment, the network'AN serving sector may assign the group ID (or group ID") to each of the pilot signals associated with the sector, for example, based on the coverage of pilot signals so that the pilot signals that have comparable coverage area, share a common group ID. The PN offset may be used as the group ID, in one embodiment. Then the network'AN transmits pilot signals with the corresponding group ID. Network AN may group the pilot signals received in one or more groups of pilot signals, in accordance with their group ID. Network AN may also choose one pilot with whom drove from each group of pilot signals as a representative pilot signal for a message about the level of the pilot signal. Network AN can also use grouping the pilot signals to perform effective control set, as further described below.

In Fig. 3 shows a variant implementation of the various sectors and associated pilot signals in the system 300 connection with many carriers. The system 300 may generally include any number of sectors, each of which is associated with one or more pilot signals having different frequencies. For illustration and clarity explicitly shown three sectors 310, 320, 330. For example, the pilot signals 311, 312, associated with sector 310, the pilot signals 321-324, associated with sector 320, and the pilot signals 331, 332, associated with the sector 330. These pilot signals are shown relative to the frequency axis 340, indicating that the pilot signals associated with a given sector, have different frequencies.

Fig. 3 additionally shows the profile 350-level dependencies from a distance, representing the coverage area of the pilot signal 321 or 322, and the profile 355-level dependencies from a distance, representing the coverage area of the pilot signal 323 or 324.

In one embodiment, the network AN (not explicitly shown)serving sector 320 may assign a group ID to each of the pilot signals 321-324 based on their areas of coverage, so that the pilot signals having essentially the same area covered by the I, share a common group ID. The shift of the PN can be used as the group ID, in one embodiment. For example, the pilot signals 321, 322 may share a common group ID (or PN offset); pilot signals 323, 324 may also share a common group ID (or shift PN). Network AN may then transmit the pilot signals 321-324 with the corresponding group ID. After receiving the pilot signals 321-324 terminal at 360 may group the pilot signals 321, 322 in the first group of pilot signals and the pilot signals 323, 324 to the second group of pilot signals in accordance with their group ID. The terminal at 360 can choose one pilot signal from each group as a representative pilot signal for a group: for example, the pilot signal 321 may be selected as the representative pilot signal for the first band pilot signal and the pilot signal 324 may be selected as the representative pilot signal for the second group of pilot signals. The terminal at 360 may measure the level of each received pilot signal or at least one pilot signal from each group of pilot signals (such as the representative pilot signal). The terminal at 360 may include only a representative pilot signal (as opposed to an entire group of pilot signals in the message about the level of the pilot signal, as described below.

In the variant shown in f is, 3, two thresholds pilot signal: add the pilot signal and remove the pilot signal" is marked on the profiles 350, 355. These thresholds can be used to determine which of the sets, the set of candidates or the set of neighbors for the terminal at 360, belongs to every pilot signal. For example, if the level of the pilot signal received by the terminal at 360 exceeds the threshold "to add the pilot signal, the pilot signal can be potentially added to the set of candidates for the terminal at 360, as explained below. If the level of the pilot signal received by the terminal at 360, falls below threshold "to remove the pilot signal, the pilot signal can be removed from the active set or the set of candidates for the terminal at 360.

In one embodiment, when the terminal at 360 moves from sector 320, it may first detect that the levels of the pilot signals 323, 324 in the second group of pilot signals fall below the threshold to remove the pilot signal, and then detecting the levels of the pilot signals 321, 322 in the first group of pilot signals. (This may be because the pilot signals 321, 322 do not have corresponding signals in adjacent sectors 310, 330, therefore, less susceptible to mutual interference.) As a result, the terminal at 360 may first send a message about the level of the pilot signal for the representative pilot signal associated with the second group PI is from signals, and then the message about the level of the pilot signal for the representative pilot signal associated with the first group of pilot signals in the network'AN in connection with these two events. The message about the level of the pilot signal may include, for example, the level shift PN and the frequency of the relevant representative pilot signal. In another embodiment, when the terminal at 360 moves closer to the sector 320, the terminal at 360 may first send a message about the level of the pilot signal for the representative pilot signal associated with the first group of pilot signals, and then the message about the level of the pilot signal for the representative pilot signal associated with the second group of pilot signals in the network AN (in connection with the gradual increase of the levels of the pilot signals in these two groups).

Next, the pilot signals in the sectors 310, 330 may also be grouped in a similar way. For example, the pilot signals 311, 312 in sector 310 can form a group of pilot signals. The pilot signals 331, 332 in the sector 330 can also form a group of pilot signals. In one embodiment, the sector 320 (or network'AN, serving it) may choose only one pilot signal from each group of pilot signals in adjacent sectors 310, 330, for example a pilot signal 311 and the pilot signal 332, and notify only on the selected pilot signals from its neighboring sectors

Grouping the pilot signals and report them, as described above, allows the terminal at relationship as an effective way to network'AN in the communication system with multiple bearing, avoiding unnecessary use of network resources. It also allows the terminal to perform at the control set effective manner, as described below.

Fig. 4A-4C show an implementation option set control in the communication system with multiple carriers. For clarity and illustration of each pilot signal is defined parameters <a PN offset, frequency>, where the shift of the PN also serves as the group ID for each pilot signal. For example, in Fig. 4A shows that the terminal at (not explicitly shown) may initially have an active set 410 includes the first group of pilot signals having the group ID "x", and the second group of pilot signals having the group ID". The first group of pilot signals includes two pilot signal defined parameters <x, f1> and <x, f2>and the second group of pilot signals includes two pilot signal defined parameters <, f1> and <, f2>. Terminal UT may also contain a set of 420 candidates, initially comprising a third group of pilot signals having the group ID "z". The third group of pilot signals has one pilot signal, a specific parameter is mi < z, f2>. Each pilot signal in the active set 410 or set 420 candidates is above a predefined threshold (e.g., threshold "to add the pilot signal described above with reference to Fig. 3).

Fig. 4 shows that in one case, the pilot signal is defined in the <z, f1>is added to the active set 410. In the result, the pilot signal with parameters <z, f2> is removed from the set 420 candidates, because both must belong to the same group of pilot signals.

Fig. 4C shows that in the other case, the pilot signal is defined in the <x, f2>is removed from the active set 410 and is not added to the set 420 candidates. This is because there remains another pilot signal that is defined in the <x, f1>belonging to the first group of pilot signals in the active set 410.

In principle, the terminal can be maintained at any of the pilot signals in the active set. Each group of pilot signals in the active set may include one or more pilot signals. The pilot signals in the set of candidates can have different ID groups; and none of the pilot signals in the set of candidates may not have the same group ID as any of the pilot signal in its active set, or any other of his other sets. This moretake mean in the case where the terminal of the at receives the pilot signal level above the threshold "to add the pilot signal and with the same group ID as an existing pilot signal in the set of candidates, it may not add the pilot signal to its set of candidates. This description of the set of candidates, is also applicable to the set of neighbors associated with the terminal at as additionally described below.

In one embodiment, the terminal at can manage a set of candidates as follows. The terminal at may maintain a set of candidates such that the pilot signals in the set of candidates all have a different group ID (in other words, each group of pilot signals has only one pilot signal). The terminal at can add the pilot signal to the set of candidates in the following cases: a) if the level of the pilot signal exceeds a threshold to add the pilot signal and the pilot signal has the same group ID as any of the existing pilot signals in the active set or the set of candidates; the terminal at can add any pilot signal with the same group ID (which the pilot signal whose level exceeds the threshold "to add the pilot signal") to the set of candidates; (b) if the pilot signal is removed from the active set and the active set does not have any pilot signal with the same group ID (as the remote pilot signal) and time set the timer remove the pilot signal has not expired, the terminal at can add any pilot signal with the same group ID (as the remote pilot signal) to the set of candidates.

In one embodiment, the terminal at can manage their set of neighbors as follows. The terminal at maintains a set of neighbors so that the pilot signals in the set of neighbors all have different ID groups (in other words, each group of pilot signals has only one pilot signal). The terminal at can add the pilot signal to the set of neighbors or delete in the following cases: a) if the pilot signal having a group ID is added to the active set or the set of candidates, any pilot signal with the same group ID as that of the added pilot signal in the set of neighbors may be removed; b) if a pilot signal having a group ID, removed from the active set, but not added to the set of candidates, and the active set does not have any pilot signal with the same group ID, that and the remote pilot signal, the terminal at can add any pilot signal with the same group ID (as the remote pilot signal) to the set of neighbors; (C) if a pilot signal having a group ID, deleted from the set of candidates, but not added to the active set and the active set does not have any pilot signal with the same group ID, and remote-pilot signal, the terminal at can add any pilot signal with the same the D group (that of the remote the pilot signal) to the set of neighbors.

Grouping the pilot signals, disclosed in the present description provides the ability to effectively manage sets in the system with multiple carriers. There may be other ways to exercise to control sets.

In Fig. 5 shows a variant implementation of the assignment of traffic channels in the communication system with multiple carriers. For example, multiple channels of direct communication line (FL), including the FL-channel 510 to FL__, FL-channel 520 on FL__b, FL-channel 530 on FL__c, FL-channel 540 on FL__d, must be transmitted from the network AN to the terminal at (both not shown explicitly). Channels return line connection (RL), including RL-channel 550 on RL__u, RL-channel 560 on RL__v and RL-channel 570 on RL__w assigned to the terminal at. In one embodiment, the network AN can assign multiple channels of direct communication lines, each of which is intended to move the reverse bit-stream power control (RPC) for each of the channels opposite the line of communication assigned to the terminal at. For example, the FL-channel 520 may be assigned to transfer the bit stream RPC RL-channel 550, FL-channel 530 may be assigned to transfer the bit stream RPC RL-channel 560, FL-channel 540 may be assigned to transfer the bit stream RPC RL-channel 570, as shown in Fig. 5. Note that in this assignment each pair of channels FL and RL are not required to have one and eachstate.

In the embodiment shown in Fig. 5, the network AN can also choose one of the FL-channels, such as the FL-channel 520, as a primary pilot signal and to inform the terminal at about the need to monitor the control channel, portable primary pilot signal (e.g., for scheduling and other purposes). In this way the terminal at may ignore other channels direct line of communication with regard to control of the control channels.

Options for the implementation presented in this description (as described with reference to Fig. 2-5), provide a number of embodiments of the group of pilot signals, control sets and assignment of traffic channels in the communication system with multiple carriers. There are other options for implementation and their practical implementation.

Fig. 6 shows a block diagram of a process 600 that may be used in one embodiment to implement the group of pilot signals and transmission of messages in a communication system with multiple carriers. At step 610, the accepted set of pilot signals associated with the sector, each pilot signal has a group ID. At step 620, the pilot signals are grouped into one or more groups in accordance with the identifiers of the groups of pilot signals. At step 630 selects the representative pilot signal from each group pilot signal is to send the message about the level of the pilot signal (as described above). In one embodiment, PN-offset can be used as a group identifier.

In Fig. 7 shows a block diagram of a process 700 that may be used in one embodiment to implement the control sets in the communication system with multiple carriers. At step 710, the measured level of the pilot signal having a group ID. At step 720 determines whether the level of the pilot signal threshold "to add the pilot signal and does not have the active set or the set of candidate pilot signal with the same group ID (that of the pilot signal whose level is greater than the threshold "to add the pilot signal"). If the result of determination at step 720 is positive ("Yes"), then followed by stage 730 on which the pilot signal with the same group ID (that of the pilot signal whose level is greater than the threshold "to add the pilot signal is added to the set of candidates. If the result of determination at step 720 is negative ("no"), then the set of candidates not added any pilot signal with the same group ID (that of the pilot signal whose level is greater than the threshold "to add the pilot signal), as shown in step 740. In the case where the pilot signal having a group ID is deleted from the active set, as shown in step 750, at step 760 determines whether the active set of any pilot signal with the same group ID (h is on and the remote pilot signal) and has not expired time, set the timer, remove the pilot signal. If the result of determination at step 760 is positive ("Yes"), then at step 730, as described above. If the result of determination at step 760 is negative ("no"), then at step 740, as described above.

Fig. 8 shows a block diagram of a process 800 that may be used in another embodiment to implement the control sets in the communication system with multiple carriers. If the pilot signal with the group ID is removed from the active set, but not added to the set of candidates, as shown in Fig. 810, or a pilot signal having a group ID is removed from the set of candidates, but not added to the active set, as shown in Fig. 820, then at step 830 determines whether the active set of any pilot signal with the same group ID (as the remote pilot signal). If the result of determination at step 830 negative ("no"), then at step 840 the pilot signal with the same group ID (as the remote pilot signal) is added to the set of neighbors. If the result of determination at step 830 is positive ("Yes"), then any pilot signal with the same group ID (as the remote pilot signal) is not added to the set of neighbors, as shown in step 850.

In the case where the pilot signal with the group ID is added to the active set or the set of candidates, as shown in step 860, at step 870 removed all the pilot signals with the same ID gr is PPI (as added pilot signal) from a set of candidates and a set of neighbors.

In Fig. 9 shows a flowchart of a process that can be used in another embodiment to implement grouping of pilot signals in a communication system with multiple carriers. At stage 910 is assigned a group ID to each pilot signal associated with the sector, based on the coverage areas of each pilot signal. At step 920, each pilot signal is transmitted with the corresponding group ID.

The device 1000 may also include block 1060 control sets made with the ability to determine whether the adopted pilot signal to one of the set of candidates or the set of neighbors associated with the terminal antibody (as described above).

Block 1070 processing can be performed with control and/or coordinate the operations of various units. Block 1080 memory may implement instructions for execution by the block 1070 processing. In some embodiments, the implementation of block 1080 memory can also store the active set, the set of candidates and a set of neighbors for terminal antibody (as described above).

For example, the device 1100 may include block 1100 assigning a group ID, made with the possibility of assigning a group ID to each of the pilot signals associated with the sector, based on the coverage area of each pilot signal; and a transmitting unit 1120, made with the possibility of transmission of pilot signals with different ID groups. The device 1100 may also include block 1130 assignment of traffic channels, configured to assign one or more channels in a direct line of communication to transfer information (e.g., control channel bit-stream RPC etc) for terminal antibody (e.g., such as described with reference to Fig. 5).
