Control channel transmission signal in wireless communication

The following description relates generally to wireless communications, and more particularly to forward link acknowledgement channels in wireless communication systems.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, material, and the like.

Reference is now made to Fig. 1, which illustrates a wireless communication system 100 in accordance with various embodiments presented herein. System 100 includes a base station 102 that can be packaged Includes multiple antenna groups. For example, one antenna group can include antennas 104 and 106, another group can include antennas 108 and 110, and an additional group can include antennas 112 and 114. Two antennas are illustrated for each antenna group; however, more or less antennas are available for each group. The base station 102 can additionally include a transmitter chain and a receiver chain, each of which can include a plurality of components associated with signal transmission and reception (eg, a processor, a modulator, a multiplexer, a demodulation transformer) , solve multiplexers, antennas, etc.), as those familiar with the technology will understand.

The base station 102 can communicate with one or more mobile devices, such as the mobile device 116 and the mobile device 122; however, it should be appreciated that the base station 102 can communicate with virtually any number of mobile devices similar to the mobile devices 116 and 122. Mobile devices 116 and 122 can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or for use in wireless communication systems Any other suitable device for communication on the 100. As depicted, mobile device 116 is in communication with antennas 112 and 114, with antennas 112 and 114 transmitting information to mobile device 116 on forward link 118 and receiving information from mobile device 116 on reverse link 120. In addition, mobile device 122 is in communication with antennas 104 and 106, wherein antennas 104 and 106 transmit information to mobile device 122 on forward link 124 and information from mobile device 122 on reverse link 126. For example, in a frequency division duplex (FDD) system, the forward link 118 can utilize a different frequency band than that used by the reverse link 120, and the forward link 124 can be used with the reverse link The frequency bands used by the path 126 are different. In addition, in a time division duplex (TDD) system, the forward link 118 and the reverse link 120 can A common frequency band is utilized, and the forward link 124 and the reverse link 126 can utilize a common frequency band.

Each antenna group and/or area designated for communication may be referred to as a sector of base station 102. For example, the antenna group can be designed to communicate to mobile devices in sectors of the area covered by the base station 102. In communications on forward links 118 and 124, the transmit antennas of base station 102 may utilize beamforming to improve the signal to interference ratios for forward links 118 and 124 of mobile devices 116 and 122. Moreover, when base station 102 utilizes beamforming to transmit to mobile devices 116 and 122 that are randomly dispersed throughout the associated coverage, the actions in neighboring cells are compared to all mobile devices that the base station transmits to the base station via a single antenna. The device can experience less interference.

According to an example, system 100 can be a multiple input multiple output (MIMO) communication system. Moreover, system 100 can utilize virtually any type of duplexing technique, such as FDD, TDD, and the like, to split communication channels (eg, forward links, reverse links, etc.). In one example, mobile devices 116 and 122 can establish one or more communication channels with base station 102; one such channel can be a communication metric for communication such as channel quality information (CQI) and/or signal to noise ratio (SNR). Control channel. Additionally, in one example, a communication or request channel can be established to allow mobile devices 116 and 122 and base station 102 to communicate request data and control data on different channels. According to an example, base station 102 can transmit beacon messages received by mobile devices 116 and 122. The mobile devices 116 and 122 can respond by transmitting control data, and the base station 102 can use the control data to allocate resources to the mobile devices 116 and 122, such as control channels, reverse link communication channels, buffers, bandwidth, and It is similar. In an instance The control channel can be a CDMA channel, an OFDMA channel, and/or a combination of one or more of the channels (or substantially any other type of communication channel). In addition, multiple control channels may exist for redundancy, dedicated channels for specific control data, and the like.

According to an example, the control channel can also be divided into one or more segments for transmitting other data, such as requesting data. Likewise, the request channel can have some bandwidth reserved for communication control data. Moreover, for security and diversity, the control channel or communications thereon can be disrupted; for example, the control channels can be specific to mobile devices 116 and 122 and sector or base station 102. In this regard, identifiers for mobile devices 116 and 122, such as media access control (MAC) IDs, and/or identifiers for base stations 102 or sectors may be specifically disrupted for channel communication. It should be appreciated that the MAC ID and/or the scrambling method can be known to the base station 102. In another example, mobile devices 116 and 122 can be connected to more than one base station of disparate control channels; thus, for example, mobile devices 116 and 122 can be required to use a disturbance to disrupt communication and use for a base station. Another type of disruption disrupts communication to another base station.

Referring to Figure 2, Figure 2 illustrates a communication device 200 for use in a wireless communication environment. For example, the communication device 200 can be a base station, a mobile device, or a portion thereof. The communication device 200 can include: a control channel requester 202 requesting establishment of a control channel from an access point or terminal; a control data definer 204 that can define and/or determine a value associated with channel control; Control data scrambler 206, which can disturb control data for its safety and/or diversity transmission; and a transmitter 208 for transmitting control over the control channel data. In an example, control channel requester 202 can attempt to establish a control channel with a base station or mobile device; this can be based on or include information related to the initial pilot or beacon type broadcast received by communication device 200. For example, once the control channel is established, the control data definer 204 can measure or otherwise determine a value or metric associated with the control channel or the received beacon/pilot communication, and use the control data scrambler 206 based communication device. The ID of 200 and the ID of the device communicating with the communication device 200 disturb the data. The communication device 200 can then use the transmitter 208 to send the disturbed data to the disparate device via the control channel.

According to another example, the control data definer 204 can control the data definition and/or fill a portion or sub-section of a channel (eg, a control channel and/or a request channel) and define and/or fill another portion or sub-item with other data. Section. Additionally, for example, control data definer 204 may fill one portion or sub-section of one channel with one type of control material and fill another portion or sub-section with another type of control data. In an example, the control channel can include a bandwidth of 1.25 MHz blocks that includes 128 carrier tones spread over a plurality of OFDM symbols. According to an example, a given MAC ID of the communication device 200 may have a 10-bit Walsh space (or 1024 Walsh sequences or sizes) to transmit control data as 128 on 8 OFDM symbols. Carrier frequency adjustment. Walsh space refers to a time domain sequence on one or more OFDM symbols that can be used to represent information and can be divided into one or more disparate channels or sequences of Walsh values. In an example, the Walsh sequence may be represented by 1024 subcarriers on 8 OFDM symbols (eg, at a rate of 1.2288 Mbps or 1.25 MHz). For example, in the case of bit representation, 5-bit The CQI channel can utilize the first 32 (0-31) values or Walsh sequences, and the 6-bit request channel can utilize the next 64 bits (32-95). Therefore, the CQI and request data can be sent on the same channel (eg, in the same Walsh space). Thus, for example, upon receipt of this communication, an access point or terminal that receives data on the channel can evaluate the Walsh space and distinguish both the control data from the request data.

As previously described, the control data scrambler 206 can scramble the control material based on the communication device 200 and/or the identifier of one or more devices in communication with the communication device 200. In one example, communication device 200 can be a mobile device that communicates with a base station having a sector ID that has a MAC ID (eg, which can be assigned by one or more base stations). The disturbances used by the control data scrambler 206 can be selected and/or formed based on the identifier. Once the data is received, the base station can use the identifier to resolve the data. It should be appreciated that the data may additionally be disturbed by the base station and descrambled by the mobile device or other communication device 200 (e.g., including disparate base stations).

Moreover, the control channel requester 202 can request communication or control channels from more than one access point or terminal in the active set; the active set can refer to an area (eg, multiple base stations or sectors in an instance) An access point or terminal to which the communication device 200 can communicate. Thus, as mentioned, the control data scrambler 206 can scramble the data in different ways for different sectors. In one example, communication device 200 can be a mobile device having a control channel or control channel associated with a CQI, a request, a power amplifier (PA) headroom, a power spectral density (PSD), and the like. One or more of these may be transmitted to the disparate channel and the same channel. Same as the access point. Moreover, the mobile device can have pilot channels that can be received by substantially all of the access points or terminals in the active set of mobile devices. To this end, for example, since the sector IDs may vary from sector to sector (and may not have been assigned a MAC ID at this time), the unique ID of the mobile device may be used to disrupt pilot channel communication.

Referring now to Figure 3, Figure 3 illustrates a wireless communication system 300 that implements communication reverse link acknowledgment. Wireless communication system 300 includes a base station 302 that communicates with mobile device 304 (and/or any number of disparate mobile devices (not shown)). For example, base station 302 can transmit information to mobile device 304 over the forward link channel; in addition, base station 302 can receive information from mobile device 304 over the reverse link channel and send a forward link acknowledgement to Confirm reverse link information. Moreover, in an example, wireless communication system 300 can be a MIMO system.

Base station 302 can include a reverse link channel assigner 306 that can process requests for reverse link channels and establish reverse link channels based in part on desired resources; a communication descrambler 308 that can descramble The communication received on the reverse link; and a communication interpreter 310 that can derive data from the divided communication on the channel. The mobile device 304 can include a control channel requester 312 that can request a channel for communication control data; a control channel divider 314 that can split a channel for communicating a plurality of control data (or request data) elements; A communication scrambler 316 can disrupt the communication based at least in part on the ID (e.g., MAC ID) of the mobile device 304.

According to an example, the mobile device 304 can request the establishment of the reverse link channel from the base station 302 via the control channel requester 312; for example, this can be returned The beacon should be sent by the base station 302. In this example, the request may include information such as CQI, SNR information, and the like based in part on the beacon symbol; the reverse link channel assigner 306 may utilize this information to assign channels and resources dedicated to the action to the action device. As described, base station 302 is available for control channels, request channels, pilot channels, other channels, and/or combinations thereof for mobile device 304. In addition, the channels may be assigned depending on the MAC ID assigned to the mobile device 304 and/or depending on the channel type. In addition, the assigned channels can be divided to send multiple control values, request values, or other data values to maximize channel efficiency.

To this end, in this regard, control channel divider 314 can utilize the channel. For example, the control channel can include a 1.25 MHz block that spans a given frame (which can include 128 subcarriers on 8 OFDM symbols). Control channel divider 314 may divide the channel into one or more sub-sections for transmitting and/or multiplexing information on the channel. In this example, 128 subcarriers may be associated with 8 OFDM symbols that are allowed to transmit 1024 available Walsh sequences (or 10 bit space). Thus, for example, a channel can be partitioned to allow for several Walsh sequences for a given control profile. In addition, the channel can use common interleaving and Walsh spreading in a given control channel. It should be appreciated that the channels may also be partitioned in other ways, such as by a set of OFDM symbols, a time period for transmitting symbols, and the like.

According to an example, control channel divider 314 may partition the control channel into one or more logical channels for additional control information (such as channels for CQI information, request data, PA headspace data, and PSD indication). According to an example, the logical channel can have a configurable periodicity (such as in units of 8 frames). Each logical channel may require 2 ⁿ Walsh sequences to facilitate bit communication, where n is the number of bits required. It should be understood that other numbers, sizes, or representations of the sequences may also be desirable (eg, multiples of two plus a certain number, any integer, non-integer size, representations other than integers, etc.). According to an example, CQI information may require 5 bits (or 2 ⁵ = 32 Walsh sequences) to transmit valid data, and request and PA headspace data may require 6 bits (or 64 Walsh sequences). And the PSD indication data may require 4 bits (or 16 Walsh sequences) to transmit data. Therefore, 1024 Walsh sequences are sufficient to process 64+64+32+16=176 required sequences. Therefore, the information can be transmitted redundantly with other information and the like (for the sake of reliability with respect to stronger transmission power and/or repeated transmission). In addition, the communication scrambler 316 can confuse the channel, the actual physical channel, and/or the logical channel according to the identification criteria. In an example, an identifier of the mobile device 304, such as a MAC ID, may be used to disrupt the channel; in addition (or other), the scrambling may be associated with a sector identifier corresponding to the base station 302. According to an example, for example, the control channel or logical channel can be disturbed differently depending on the type of data or communication.

Once disrupted, the mobile device 304 can broadcast data on the control channel, where the control channel can be a CDMA channel. The base station 302 can receive the data and utilize the communication descrambler 308 to descramble the data. For example, the communication descrambler 308 can utilize, for example, the MAC ID of the mobile device 304 (which may have been received during the channel request) and/or the sector ID to, for example, descramble the channel. In one example, for example, different information can be used to descramble the disparate channel. Once the part of the channel (logical channel or physical channel) is descrambled, the communication interpreter 310 may determine the data transmitted via the channel based on the logical channel configuration as described (eg, which portions of the channel are used for which control or request data, etc.). It should be appreciated that the logical channel configuration may be predetermined or known to base station 302 and/or mobile device 304, transmitted from mobile device 304 to base station 302 during initial channel setup, using inference techniques to determine and/or the like. .

For example, it should be appreciated that the mobile device 304 can request a plurality of control channels from the reverse link channel assigner 306 of each base station. According to an example, mobile device 304 can establish (via control channel requestor 312) a CDMA control channel and an OFDMA control channel. Control channels can be established with the same or different base stations. In addition, different data or control information can be transmitted on the control channel. Moreover, for example, the communication scrambler 316 can disrupt control information or data communications in different ways depending on the respective base station or its sector.

Referring now to Figure 4, there is shown an example communication hyperframe 400 for wireless communication. The hyperframe can include a plurality of symbols (such as OFDM symbols) that include a plurality of subcarriers. A row may represent an OFDM symbol period, which is a collection of frequency subcarriers (or carrier tones) for a given time period. The hyperframe can contain substantially any number of symbol periods, and the symbol period can include substantially any number of carrier tones. As shown, the hyperframe can include a plurality of symbol periods during which control data is transmitted. As described above, these may also represent Walsh sequences. Control data may be transmitted on a plurality of subcarriers such as subcarrier 408 and the like. Additionally, the symbol period can be partitioned into one or more segments representing a portion of the available frequencies. Although a group of four symbols is shown in each section for purposes of explanation, it should be understood that virtually any number of groups may be included within the section.

According to an example, the illustrated segment may represent a control channel that is split into one or more logical channels for transmitting multiple types of control information. For example, one or more logical channels can be used to transmit CQI information, request data, PA headspace information, and/or PSD data. In addition, the segments may represent different physical control channels for transmitting CDMA control data, pilot channel data, dedicated control information, feedback data (eg, in a MIMO configuration), and/or reverse link access channel information. To this end, the segments can be disturbed in different ways to additionally distinguish the control data and/or relate the data to one or more disparate sectors. As described, the mobile device can establish a control channel with one or more sectors. Since the mobile device can use the sector identifier (and/or mobile device identifier) to scramble the information, the scrambling can be different for the logical channel or segment of the illustrated hyperframe. Additionally, as described, the one or more channels may be associated with a pilot channel for transmitting pilot data for which no reverse link is established; in this regard, the disturbance may only be with the mobile device related.

According to another example, the control section can be part of a communication channel (eg, a 1.25 MHz physical channel section such as a reverse link CDMA dedicated control channel (R-CDCCH)), where each mobile device or other access terminal The machine control channel can be distributed over a physical channel segment or at least a portion of the R-CDCCH (eg, an R-CDCCH sub-segment). In addition, this physical channel segment can hop on a larger frequency band (eg, 5 MHz with control channel hopping up to 4 times). To this end, different sequences related to the mobile device or access terminal can be used to disrupt the segment or sub-segment. Additionally, as described, the logical channels within the physical channel segment may be multiplexed within the physical channel segment by dividing the Walsh space associated with the segment into subsets or sub-sections (eg, by Use Walsh extensions and co-interlace). In this example, each subset may correspond to a logical channel and the mobile device may select a Walsh sequence within a subset corresponding to the logical channel. This selection may be based on several factors, such as random assignment, sequential assignment, based on information to be sent, based on information size, based on information efficiency requirements and the like. As shown, for example, control information can be sent in a plurality of symbol periods 402, 404, and 406 for a given frame or frame.

As described above, the channel segment can be divided into Walsh spaces, where the transmitted sequence represents a Walsh sequence. For example, the sequence of symbols 408 on OFDM symbols 402, 404, and 406 shown in the first channel shown (eg, the logic or entity as described in the two examples above) may be an indication material (which may be solved) Part of the Walsh sequence of a single control channel translated into binary data. In an example, the control channel can be a CDMA control channel (e.g., R-CDCCH), which can be further partitioned in the following format as described.

In this regard, the Walsh sequence selected for the channel can represent information for the above channels. In the 5-bit space of CQI, 32 Walsh sequences are needed to represent the value of this space. Therefore, the first 32 Walsh sequences (0-31) available for use on the channel can be used for this expression. In the 6-bit space of the request channel, 64 Walsh sequences are needed to represent the possible values for this space. Therefore, the next 64 Walsh sequences (32-95) can be used for this expression. This sequence continues so that the logical channels shown above can be transmitted in a single physical channel by utilizing the available Walsh sequences of the physical channels to convey information about the logical channels. This minimizes the total number of channels necessary to transmit control and request (and other) data and thus makes wireless communication more efficient.

Moreover, as described, different disturbances (eg, based on the identifier of the mobile device and/or sector) can be used to disrupt the physical channel segment. For example, a physical channel segment can be scrambled based on an action identifier (eg, a MAC ID) and/or a sector ID. This may require a solution to the channel segment rather than the logical channel to save the resource. Alternatively, scrambling/descrambling may require a fast Hadamard transform (FHT) engine for each scrambling. Using this method, only a single common FHT engine for the entire channel segment is required.

The logical channels shown above can be defined by the information contained therein. For example, in one example, the CQI channel can have a 4-bit wideband channel quality indicator and a 1-bit forward link serving sector information. A requesting logical channel that can be used to request a new reverse link resource from a serving sector can carry a plurality of quality of service (QoS) levels, buffer levels and/or delay limits, and the like. In addition, the PA headspace channel can include a maximum achievable received CoT value, which can be calculated by using pilot CoT feedback or, for example, in-band. Also, the PSD indication channel can carry information related to the newly assigned PSD value of the proposed data (such as the ratio of the reverse link strength of the serving base station to the reverse link strength of the strongest non-serving base station). For the above values, borrow This information can be conveyed in a single Walsh sequence across the physical channel by using a Walsh sequence that matches the desired value (where the total number of available Walsh sequences is divided into equal values).

Referring to Figures 5 through 6, Figures 5 through 6 illustrate a method for defining a logical channel for a control channel. Although the method is shown and described as a series of acts for the sake of simplicity of explanation, it should be understood and understood that the method is not limited by the order of the acts, as some acts may be in a different order and/or in accordance with one or more embodiments. Other actions shown and described herein occur simultaneously. For example, those skilled in the art will understand and appreciate that the method can be represented as a series of related states or events (such as in a state diagram). In addition, not all illustrated acts may be required to implement a method in accordance with one or more embodiments.

Referring now to Figure 5, there is shown a method 500 of facilitating transmission of control data on one or more disturbing logical channels. At 502, control data is defined. In an example, the control data can be associated with one or more mobile devices and/or communications thereof. For example, control data may be associated with channel quality indications for a given sector or access point; information may be obtained in various ways, such as by measuring metrics, measurements related to beacon signals transmitted by the sector. A measure related to the communication of the established channel, and the like. In other examples, as described, the control data may be related to request data, PA headspace data, PSD information, pilots, MIMO feedback, and the like. In addition, the channel can also be associated with communication or non-control data. At 504, the data can be mapped to a logical channel for transmitting control data. The physical channel or channel segment can be segmented into one or more logical channels for transmitting control data as described in the other figures. Road.

At 506, the control channel can be associated with a Walsh sequence. As previously described, a physical channel or segment thereof can have a Walsh space that is defined to facilitate associating a sequence of symbols, such as an OFDM symbol, with a data bit over time. In this regard, the Walsh space associated with the physical channel can be partitioned into sequences for different logical channels. For example, the control parameter can have the first 64 Walsh sequences (0-63), and the next parameter can have the next 16 sequences (64-79), etc.; in this regard, the logical control channel can be given a given The Ershi sequence is associated, and the data bits that need to be transmitted can be defined by the Walsh sequence. Thus, in an example using one of the above sequences, a first control parameter having 64 Walsh sequences may define a 6-bit codeword group (2 ⁶ = 64), and a second control parameter may define a 4-bit codeword group.

At 508, the control channel and/or the Walsh sequence associated with the control channel can be disturbed based on the device and/or sector ID. For example, this visual control data and/or control channel depends. In one example, the data may be pilot data transmitted to a non-specific sector; therefore, the sector ID may not be used to disrupt the data since the associated sectors are part of multiple and active sets. However, by way of example, in this example, a device ID (eg, a MAC ID) can be used to disrupt communications to distinguish from control data of other devices. Additionally, in an example, the Walsh sequence of a given logical channel can be disturbed. At 510, for example, the scrambled data is transmitted to one or more sectors.

Referring to Figure 6, Figure 6 illustrates a method 600 that facilitates receiving and interpreting disturbed and/or partitioned control data. At 602, a control channel can be determined from the received physical channel communication. For example, the physical communication channel can be split into A section that shoots multiple types of data (controls, requests, etc.). Additionally, the channel section can be partitioned into one or more logical channels for multiplexing control data to be transmitted over the available Walsh sequence. According to an example, a logical channel can be provided for control data related to CQI, request material, PA headspace information, PSD information, and/or the like. As described, the logical channel can be multiplexed such that a portion of the total available Walsh sequence of the channel can be assigned to the disparate control data field.

Additionally, the fields, logical channels, and/or channel segments can be scrambled based on sector and/or device identifiers. At 604, the control channel can be descrambled based on the identifiers. As mentioned, one or both of the IDs can be used to resolve communications based on the type of communication and/or information used to disrupt the communication. At 606, control data on the control channel can be interpreted based on the Walsh sequence associated with the control channel. As mentioned, the data can be associated with a portion of the available Walsh space of the channel; the data can be interpreted from the associated Walsh sequence transmitted. At 608, control data from the channel can be processed. This may include, for example, adjusting channel parameters based on received data, storing and/or recording values based on data, closing channels, transmitting channels, opening new channels, dividing channels, and/or wirelessly based on received control data. Any imaginable operation related to communication.

It will be appreciated that inferences regarding schemes for partitioning and/or descrambling control channels may be made in accordance with one or more aspects described herein. As used herein, the term "inference" generally refers to the process of inferring or inferring the state of a system, environment, and/or user from a group of observations captured by an event and/or data. For example, inference can be used to identify a particular condition or action, Or the probability distribution of the state can be generated. Inference can be probabilistic, that is, based on the calculation of the probability distribution of the state based on consideration of data and events. Inference can also refer to techniques used to compose higher-order events from a set of events and/or data. Whether or not the event is closely related in time, and regardless of whether the event and the data are from one or several events and data sources, the inference results in a new event or action from a set of observed events and/or stored event data.

According to an example, one or more of the methods presented above can include making inferences regarding selection or determination of control channel partitioning. As a further illustration, inference can be made based in part on prior partitioning selection, partitioning of other control channels, data contained within the control channel, and the like. In addition, inference can be made regarding descrambling control channel communication based on previous disturbances, IDs or versions of mobile devices and/or sectors, other measurable information, and/or the like. It is to be understood that the above examples are illustrative, and are not intended to limit the inferred number of the embodiments and the manner in which the various embodiments and/or methods described herein.

According to an example, for example, mobile device 700 can request and establish a control channel link with a base station or other access point. Control channel definer 706 can divide the control channel into one or more physical channel segments as previously described. For example, the control channel section can be associated with one or more established control channels with one or more base stations. Control channel definer 706 can further divide one or more channel segments into logical control channels for transmitting a portion of the control information. For example, control channel definer 706 can partition the total number of available Walsh sequences of physical channels into the one or more logical channels. In this regard, control channel definer 706 allows a portion of the Walsh sequence to be assigned to one or more control data values, as described with reference to the other figures. In an example, a 1.25 MHz channel may have a 10-bit Walsh space as 128 carrier tones on 8 OFDM symbols; this provides 1024 different Walsh sequences for logical control channels. Thus, the sequences can be separated for use in logical channels; the partitions can be sequential or random as described herein, defined by one or more algorithms, and the like.

Additionally, control channel scrambler 708 can disrupt communication on the channel based on the identifier of mobile device 700 and/or the sector associated with mobile device 700. As described, for example, the scrambling can be associated with a mobile device only ID, where the data is related to the pilot channel of the mobile device 700. In addition, for example, the disturbance may be based on a physical channel, on a channel segment, and/or basis The logical channel is carried out. Once disturbed, data can be transmitted on the control channel by modulation using modulator 714 and transmitting on transmitter 716. For example, although shown as separate components, it should be appreciated that control channel definer 706, control channel scrambler 708, and/or the functionality described herein may be implemented in processor 710 in whole or in part. Additionally, memory 712 can include instructions related to performing the functions described above or related to the functions described above, such as a scrambling algorithm, channel definition, and/or the like.

As described, the logical channels, segments, and/or physical channels can be disturbed; the control channel descrambler 818 can be based on pre-configured, inferred techniques, information received from one or more mobile devices 804 or other base stations 802, The potential network communicating with the base station 802 and/or the like is disturbed by an appropriate level. Once the channel is descrambled, control channel interpreter 820 can be affected to derive information from the control channel. As described, the channel can be divided into one or more logical channels and one or more segments that can use a shared Walsh space. In an example, the channels may be logically separated for a number of control values based on a number of Walsh sequences and available channels needed to interpret the data.
