     DETAILED DESCRIPTION 
     In some wireless systems, there may be a need to minimize the amount of interference between sectors. Specifically, when a client device is in between two sectors (which may have the same or similar signal quality) of the same site served by a wireless access point/base station, the client device may connect to either of the sectors. However, the client device may suffer intra site sector interference from the other sector which was not selected. This interference may be especially severe in systems in which the sectors use the same frequencies (for example, same channels or bands). Moreover, in some high data rate or capacity systems such as Long Term Evolution to the home (LTTH), a client device may need to be able to receive data at very high data rates, so a relatively high signal-to-interference-plus-noise (SINR) ratio may be needed (so the reduction of the adjacent sector interference may enable in part the very high data rates required of LTTH). Although some of the examples refer to LTTH, the subject matter disclosed herein may be used in other wireless systems as well. 
     In some example embodiments, there is provided a way to reduce the interference between sectors within a given site. 
       FIG. 1A  depicts an example base station  110  including sector antennas configured to have sectors  112 A-C/ 114 A-C, in accordance with some example embodiments. In some example embodiments, the base station  110  may include 6 sector antennas, one for each sector, although the sectors may be implemented by other quantity of antennas as well and/or may include beam forming and steering as well. For example, a first sector antenna may have an antenna pattern that corresponds to the radiation pattern or sector, such as sector  114 A; a second sector antenna may have a radiation pattern or sector, such as sector  112 C; and so forth for each sector antenna. 
     In some example embodiments, sectors  112 A-C/ 114 A-C may be on different frequencies, in accordance with some example embodiments. For example, sectors  114 A,  114 B, and  114 C may be on a first frequency (for example, a channel on the 1.8 GHz band), while sectors  112 A,  112 B, and  112 C may be on second frequency (for example, a channel on the 2.6 GHz band), although the sectors may be assigned to other frequencies and bands as well. 
     In some example embodiments, sectors  112 A-C/ 114 A-C may be configured, so that a given sector has a sector boundary that is at about the middle of an adjacent sector. To illustrate, sector  114 A may have a sector boundary that is at about the middle of sector  112 C. In the example of  FIG. 1A , the beam  112 C may be about 60 degrees from beam  114 A (as measured from the centers of each beam), while beam  114 B may be about 60 degrees from beam  112 C, and so forth. In this example, the sector boundary (which is between beam  114 A and bean  112 C) is at about 30 degrees. In some example embodiments, the sector pattern may be fixed for a given base station. For example, the vacillate deployment the base station may include a fixed sector pattern, such as the 60 degrees between the centers of each sector beam as shown in  FIG. 1A . Although some examples refer to 60 degrees between the centers of each sector beam, this angle may vary to a certain degree as well. For example, the centers of each beam can vary by +/1 0.5 degrees, 1 degree, 2 degree, 3 degrees, 4 degrees, 5 degrees, 10 degrees, 12 degrees, 15 degrees, as well as other values (which may depend on the beam width of the sector beam and other factors as well to avoid interference and provide good signal quality between adjacent sectors). To illustrate further, the sector pattern may include 12 sectors each spaced at about 30 degrees, in which case adjacent sectors may be at different frequencies as in the 6 sector example. 
     In some example embodiments, a network node, such as a resource allocator, may assign resources to a given client device, such as customer premises equipment (CPE)  194 A. For example, the resource allocator may assign a given sector such as sector  114 A operating on a first frequency or assign sector  112 C which is on a second frequency. In this example, base station  110  may select or configure an antenna to transmit on a first frequency on frequency band one and sector  114 A. As sectors  114 A and  112 C are in different frequency bands and have sector boundaries that are at about the middle of an adjacent sector, CPE  194 A may operate on sector  114 A without receiving interference from adjacent sector  112 A (where another CPE may be operating for example). 
       FIG. 1B  depicts CPE  194 A between sectors which are not configured as noted above with respect to  FIG. 1A . As can be seen in  FIG. 1B , the CPE is in between two sectors of relatively similar signal quality. When this is the case, the CPE may select a given sector  124 A for example but suffer interference from sector  122 C, which is on the same frequency (or a band of frequencies as well). 
       FIG. 2A  depicts a system  200 , in accordance with some example embodiments. System  200  may include base station  110  including sectors  112 A-C and  114 A-C and CPE  194 A as described above with respect to  FIG. 1A . 
     System  200  further includes a resource allocator  290 , in accordance with some example embodiments. Resource allocator  290  may allocate one of the sectors  112 A-C and  114 A-C to a CPE, as well as assign a frequency for use on the allocated sector. 
     In the example of  FIG. 2A , an example LTTH system is also depicted, in accordance with some example embodiments. In the case of LTTH, CPE  194 A may serve as a radio interface to a wireless access network (for example, LTE although other types of radio access technologies may be used as well). This interface may enable reception from the wireless access network on a given sector, such as sector  114 A and/or the like for example. Furthermore, CPE  194 A may serve as a local interface, such as a router, for other coupled devices at a location or home, such as user equipment (UE)  120 A, UE  120 B, and/or the like. In the case of LTTH, the base station  110  may include an antenna configured to transmit a downlink at an allocated sector such as sector  114 A at a first frequency, to CPE  194 A, and this downlink may be at a relatively high data rate/capacity while conserving use of spectrum. For example, a 20 MHz channel in the 1.8 GHz band may require high SINR to provide the high capacity (for example, up to 100 Mbps and exceeding, although other rates may be implemented as well). 
     Although  FIGS. 1A and 2A  describe the antenna sectors  112 A-C/ 114 A-C being used for downlink transmission from the base station to the CPE  196 , the CPE may also use for example electronic beam forming and/or steering to transmit to the base station  110  (although beam forming and steering may be used for example to transmit and/or receive and at the CPE and/or the base station as well).  FIG. 2B  depicts the system of  FIG. 2A  and depicts the beam  198  formed by the CPE  194 A. Beam  198  have the same or different shape and pattern as sector beam  114 A. Resource allocator  290  may allocate to CPE  194 A the resources to enable transmission of an uplink via an antenna at CPE  194 A having the beam (for example, radiation pattern)  198  (which may be at a band one frequency or another frequency as well). Alternatively or additionally, CPE  194 A may receive (via wired and/or wireless connections) the location of the base station  110 , which enables the CPE  198 A to determine the direction, shape, and the like of beam  198 . In some example embodiments, CPE  198 A may receive the location of the base station a wireless connection (for example, CPE  198 A may operate in an omnidirectional mode at a lower rate during the configuration of the CPE  198 A, and once determining the location of the base station  110  enter into a higher data rate mode with beam  198 . 
     Moreover, although  FIGS. 1A and 2A -B depict a single base station and CPE, other quantities of base stations and/or CPE may also be implemented as well. Furthermore, although a single site having sectors  112 A-C/ 114 A-C is depicted, additional sites including sectors may be deployed as well in accordance with some example embodiments. In addition, although  FIG. 2A  depicts six sectors, other quantities of sectors may be implemented as well. 
       FIG. 3  depicts an example of a process  300  for allocating resources including allocating an antenna sector to a client device, such as a CPE, in accordance with some example embodiments. 
     At  305 , a channel quality indicator may be determined, in accordance with some example embodiments. For example, CPE  194 A may measure an indication of the channel quality by for example determining SINR and/or other metrics for sector  114 A as well as other sectors, such as sector  112 C. 
     At  310 , the determined channel quality indicator may be sent, in accordance with some example embodiments. For example, CPE  194 A may send the measured channel quality indicator to resource allocator  290 . The resource allocator  290  may then determine which sector satisfies a threshold channel quality, such as SINR, to CPE. And, the resource allocator  290  may allocate a sector based on the channel quality indicator information. For example, the resource allocator  290  may have a threshold SINR for a CPE in order to provide a given data rate to the CPE. If the channel quality indicator meets or exceeds the threshold SINR at a given sector, that sector can be assigned to the CPE. But if the channel quality indicator does not meets or exceed the threshold SINR at the given sector, that sector should not be assigned to the CPE (unless the threshold is revised or some other adjustment, such as a reallocation of the allocated CPEs, is performed). In some example embodiments, resource allocator  290  may take into account the modulation and coding scheme at CPE  194 A and the received channel quality indicator, when determining which sector to allocate to the CPE. Moreover, the resource allocator may take into account the received channel quality indicator (as well as modulation and coding scheme, load at a given sector, and/or the like) received from a plurality of CPEs, when determining which sector to allocate to the CPE  194 A (as well as other CPEs). Furthermore, the resource allocator may reallocate resources among CPEs to optimize channel quality among the CPEs. 
     The allocation of a sector noted above may be based on location information. If the location of the base station and CPE are known (as well as the sector pattern), then the sector to be allocated to the CPE may also be performed based on location alone (or in combination with the channel quality indicator). For example, the CPE may report its location to the base station, which may then assign a sector for downlink transmission based on the location of the CPE and the corresponding sectors covering the location of the CPE. Alternatively or additionally, the CPE may determine the base station location (for example, the location may be determined or reported to the CPE), and form a beam, such as beam  198 , to enable transmission of an uplink to the base station. 
     At  320 , a resource, such as a frequency and sector allocation, may be received, in accordance with some example embodiments. For example, resource allocator  290  may determine which sector to assign as noted above, and send the allocated sector and band to CPE  194 A. The allocation may include other information as well, such as modulation, coding, and/or the like. When the CPE receives the allocation, CPE  194 A can operate on the allocated sector, such as sector  114 A for example. 
       FIG. 4  depicts an example of a system  400 , in accordance with some example embodiments. System  400  is similar to system  200  in some respects, but depicts the introduction of a CPE  194 B at sector  114 A. When this is the case, the network may trigger process  300  in order to allocate resources to CPE  194 B, which may also result in a reallocation to CPE  194 A as well. For example, the CPEs in the site served by base station  110  may receive their resource allocation. This resource allocation may be dynamic in the sense that it may change from time to time, such as after the introduction of another CPE, the departure of a CPE, changing conditions in the network, such as load, and/or other reasons as well. 
     In the example of  FIG. 4 , when CPE  194 B enters the site  400 , process  300  may be triggered and result in band one sector  114 A being allocated to CPE  194 B for example. Resource allocator  190  may also allocate (or reallocate) resources to the other CPEs. Specifically, resource allocator may take into account the load on each sector, in accordance with some example embodiments. For example, CPE  194 A-B may both be allocated to sector  114 A on band one, but the resource allocator may as part of process  300  subsequently reallocate CPE  194 A to sector  112 C if sector  114 A is overly burdened with a heavy traffic load (or for some other reason such as a beneficial SNIR in another sector, or to optimize the overall network capacity where all of the sites are taken into account), while sector  112 C is lightly loaded. Thus, in some example, embodiments, the resource allocator may perform load balancing by allocating sectors  112 A-C/ 114 A-C. 
     Although the example above describes the resource allocation being performed by the network, a client device, such as CPE and/or any other device may perform the allocation as well. Further, the resource allocation may be performed dynamically such that optimum total capacity across CPE and sectors is determined at any given moment. 
     Example Use Case 
     In some example embodiments, the CPE, such as CPE  194 A,  194 B, and/or the like ( FIG. 4 ), may be used in a LTTH implementations. During the initial power-up and installation of for example CPE  194 A, the location of CPE  194  may be sent via a wired or wireless link to resource allocator  290 . In response, the resource allocator may identify which site, such as which base station from among a plurality of base stations, and which sector, from among sectors  114 A-C and  112 A-C, should be assigned to CPE  114 A. The resource allocator  290  may also calculate the direction from the CPE  194 A to the selected site (for example, base station  110 ) to enable CPE  194  to beam steer to the base station  110 . The resource allocator may provide the determined site, sector, and/or direction to CPE  194 A (via wireless and/or wired links). The direction to the site/base station may be used by the end-user to place the CPE  194 A (or its antenna(s)) on for example on a side of the home/premises as the direction to the site/base station. The CPE  194 A may then beam form or steer its directional antenna towards the direction of the site and/base station, and then transmit and/or receive on the assigned site and sector (and mapped frequency). 
     In some example embodiments, carrier aggregation may be implemented as well. Referring again to  FIG. 1A , CPE  194 A having access to carriers from sector  114 A and sector  112 C may enter into a carrier aggregation mode (for example, in which the carrier from sector  114 A is a primary carrier and the carrier from sector  112 C is the secondary carrier). To illustrate, the CPE  194 A may perform measurements of the carriers associated with sectors  114 A and  112 C, and if the measurements satisfy a quality threshold (for example, an SINR threshold or target), the CPE  194 A may enter into the carrier aggregation mode. However, if CPE  194  is in a location covered by only a single sector (and/or the quality thresholds are not satisfied), the CPE may decide to not enter into a carrier aggregation mode. 
       FIG. 5  depicts an example of an apparatus  500 , in accordance with some example embodiments. The apparatus  500  may comprise a CPE as described herein and/or a user equipment (UE), such as a smart phone, a tablet, a cell phone, a wearable radio device, and/or any other radio based device including for example a wireless access point/base station. Moreover, the resource allocator  290  may comprise circuitry as described with respect to apparatus  500 , although the resource allocator  290  may be implemented with a wired interface to other devices (rather than the wireless interfaces shown at  FIG. 5 ) as well. The resource allocator  290  may be provided as a service, such as a cloud/internet service accessible to the network, base station, CPEs, and/or other devices.
