[0001] One or more example embodiments relate to methods, apparatuses and/or computer-readable storage mediums for allocating wireless beam resources according to a number of served customer premises equipments within a service area.
Discussion of Related Art
[0002] Modern wireless systems for both mobile and fixed user services employ wireless beam technology. Within a service area, such as a sector of coverage of such a wireless system, one or more wireless beams are employed to serve users. Conventionally, the wireless beams within a service area are activated one at a time with equal duration and equal resource allocation.
SUMMARY
[0003] In a fixed wireless beam approach, a service area (e.g., a sector) is divided into a number of approximately equal sized (e.g., beam width) fixed beams. Each beam is given an equal duration and all wireless resources are directed to that one active beam at a given time to serve only customer premises equipments (CPEs) who can be served by the one active beam. However, the number of CPEs and/or the amount of wireless resources required across CPEs within each beam may be (and typically is) unequal. As a result, the users and their needs are not served fairly on the basis of need. One example scenario in which uneven distribution of CPEs occurs is a fixed wireless application in which wireless base stations are mounted on lampposts illuminating homes and businesses within the wireless base station's coverage area. In such cases, beams that point across the street may encompass fewer homes (and, thus, fewer CPEs) than beams that point side-ways along the streets.
[0004] One or more example embodiments provide methods, apparatuses and computer readable storage mediums in which an amount of resources allocated to a beam is proportional to the needs of the beam at a given time, and may be different from other beams in the service area. According to at least one example embodiment, the amount of wireless resources allocated to a beam may be a function of the amount of wireless resources such as time, frequency, spatial domain, power, or the like, allocated to the beam. The total needs of CPEs served by a given beam may be a function of the number of CPEs, an amount of data (e.g., per CPE and in aggregate) taking into account different quality of service (QoS), scheduling priority factors, and the like.
[0005] At least one example embodiment provides a radio access network element providing wireless resources via a plurality of wireless beams to serve customer premises equipments in a service area of a wireless network. The radio access network element includes: a memory storing computer- readable instructions; and at least one processor. The at least one processor is configured to execute the computer-readable instructions to: compute a first amount of wireless resources to be allocated to a first of the plurality of wireless beams based on a total amount of wireless resources available across the plurality of wireless beams within the service area and individual wireless resource needs of the first of the plurality of wireless beams; and allocate the first amount of wireless resources to the first of the plurality of wireless beams.
[0006] At least one other example embodiment provides a radio access network element providing wireless resources via a plurality of wireless beams to serve customer premises equipments in a service area of a wireless network. The radio access network element includes: a memory storing computer-readable instructions; and at least one processor. The at least one processor is configured to execute the computer-readable instructions to: allocate a first amount of wireless resources to a first of the plurality of wireless beams based on first wireless resource needs of first customer premises equipments served by the first of the plurality of wireless beams; and allocate a second amount of wireless resources to a second of the plurality of wireless beams based on second wireless resource needs of second customer premises equipments served by the second of the plurality of wireless beams, the second amount of wireless resources different from the first amount of wireless resources.
[0007] At least one other example embodiment provides a method for allocating wireless resources via a plurality of wireless beams to serve customer premises equipments in a service area of a wireless network, the method comprising: computing a first amount of wireless resources to be allocated to a first of the plurality of wireless beams based on a total amount of wireless resources available across the plurality of wireless beams within the service area and individual wireless resource needs of the first of the plurality of wireless beams; and allocating the first amount of wireless resources to the first of the plurality of wireless beams.
[0008] At least one other example embodiment provides a method for allocating wireless resources via a plurality of wireless beams to serve customer premises equipments in a service area of a wireless network, the method comprising: allocating a first amount of wireless resources to a first of a plurality of wireless beams based on first wireless resource needs of first customer premises equipments served by the first of the plurality of wireless beams; and allocating a second amount of wireless resources to a second of the plurality of wireless beams based on second wireless resource needs of second customer premises equipments served by the second of the plurality of wireless beams, the second amount of wireless resources different from the first amount of wireless resources.

As will be appreciated, depending on the implementation of the CPE 105, the CPE 105 may include many more components than those shown in FIG. 2B. However, it is not necessary that all of these generally conventional components be shown in order to disclose the illustrative example embodiment. [0036] The memory 270 may be a computer readable storage medium that generally includes a random access memory (RAM), read only memory (ROM), and/or a permanent mass storage device, such as a disk drive. The memory 270 also stores an operating system and any other routines/modules/applications for providing the functionalities of the CPE 105 to be executed by the processor 250. These software components may also be loaded from a separate computer readable storage medium into the memory 270 using a drive mechanism (not shown). Such separate computer readable storage medium may include a disc, tape, DVD/ CD-ROM drive, memory card, or other like computer readable storage medium (not shown). In some embodiments, software components may be loaded into the memory 270 via one of the various interfaces 290, rather than via a computer readable storage medium.
[0037] The processor 250 may be configured to carry out instructions of a computer program by performing the arithmetical, logical, and input/output operations of the system. Instructions may be provided to the processor 250 by the memory 270.

[0039] FIG. 3 is a flow chart illustrating a method of allocating wireless resources to wireless beams in a service area according to an example embodiment. For example purposes, the method shown in FIG. 3 will be described with regard to FIG. 1. However, example embodiments should not be limited to this example. Rather, as mentioned above, the example embodiment shown in FIG. 3 may also be applicable to a CRAN.
[0040] In describing the method shown in FIG. 3, it is assumed that the base station 1 15 communicates with the CPE 105 over a wireless link via the i-th beam among the plurality of wireless beams 130 in the service area. It is further assumed that the i-th beam serves K number of CPEs, which transmit J different data types. In this example, K is a relatively large number of CPEs, and J may be 1 , 2, 3 or more data types.
[0041] Referring to FIG. 3, at step S302 the base station 1 15 determines the total wireless resource (or traffic) needs B_N_i(t) of the i-th wireless beam at time ί (also referred to herein as wireless resource needs of CPEs served by the i-th wireless beam) . In one example, the base station 1 15 determines the total wireless resource needs of the i-th beam by aggregating the then prevailing CPE demand across the K CPEs served by the i-th beam as weighted by Quality of Service (QoS) and scheduling priority factors. According to at least one example embodiment, the total wireless resource needs B_N_i(t) of the i-th beam may be given by Equation [1] shown below.
B_N_ =∑k,j{u_k_d_j (t) * W_k(t) * qj(t)) [1]
[0042] In Equation [1], u_k_d J(t) is the k-th CPE's (among the K CPEs) quantity of data type j (among the J data types) associated with QoS weighting q_J for that data type and scheduler weight, W_k(t) for the k-th CPE at time i. The summation∑kj is over all K CPEs and J data types for the i-th wireless beam at time t. The scheduler weight W_k(t) is determined by the scheduler (not shown) at the base station 1 15, which takes into account factors such as channel quality for the k-th CPE at time i, etc. Each of u_k_d _j(t), W_k(t), and q_J(t) in Equation [1], as a function of time, are known at the base station 1 15 for both the downlink (DL) and the uplink (UL). For the downlink, these parameters are available to the base station 1 15 at the input buffer for the traffic that has been received for delivery to CPEs from the network. For the uplink, the CPE requests a grant for uplink transmission. Along with the request, the CPE provides a buffer status indicating to the base station how much and what type of data is to be transmitted. Thus, also for the uplink the base station 1 15 knows u_k_d J(t) and qj(t).
[0043] Returning to FIG. 3, at step S304 the base station 1 15 determines the fraction B_N_F_i(t) of the total wireless resource needs, which are attributable to the i-th wireless beam from among the plurality of wireless beams 130.
[0044] According to at least one example embodiment, the fraction B_N_F_i(t) of the total wireless resource needs of the plurality of wireless beams 130, which are attributed to the i-th wireless beam at time t (B_N_F_i (t)), may be given by Equation [2] shown below. [2]
[0045] In Equation [2], B_N_i(t) are the total wireless resource needs of the i-th wireless beam (determined at step S302), and ∑i(B_N_i(t)) is the summation of the total wireless resource needs across all of the plurality of wireless beams 130. According to at least some example embodiments, the summation may be across all beams of a sector, across an entire cell, or a cluster of cell sites in a network multiple-input-multiple-output (MIMO) context, wherein the wireless resources (e.g., time, frequency, spatial, power, etc.) may be shared. Although example embodiments are discussed with regard to proportionality, example embodiments should not be limited to this example.
[0046] At step S306, the base station 1 15 determines the total wireless resources available Total_Res_All_Beams across all of the plurality of wireless beams 130. According to at least one example embodiment, the total wireless resources Total_Res_All_Beams available across all of the plurality of wireless beams may be the total time, frequency, spatial and/or power resources available across all of the plurality of wireless beams 130 in the service area. If the service area is a sector, a cell site or cluster of cell sites, then the total time, frequency, spatial and/or power resources is known at the base station 1 15.
[0047] At step S308, the base station 1 15 determines the fraction B_S_F_i(t) of the total wireless resources, which is to be allocated to the i-th wireless beam at time t. In one example, the fraction B_S_F_i(t) is the fraction of time, frequency, spatial and/ or power resources to be allocated to the i-th wireless beam at time i.
[0048] In one example, the fraction B_S_F_i(t) of time, frequency, spatial and power resources allocated to the i-th wireless beam at time ί may be set equal to the fraction B_N_F_i(t) of the total wireless resource needs, which is attributed to the i-th wireless beam at time t, as determined at step S304 (i.e., B_S_F_i(t) = B_N_F_i(t)).
[0049] In another example, the fraction B_S_F_i(t) of the total wireless resources, which is to be allocated to the i-th wireless beam, may be proportional to the fraction B_N_F_i(t) of the total wireless resource needs, which is attributed to the i-th wireless beam at time i, as determined at step S304. The proportionality may account for actual resources available at time t, which may be less than the total resources available due to certain amount of base station resources set aside for overhead channels, or for other services such as broadcast services.
[0050] Still referring to FIG. 3, at step S310, the base station 1 15 computes the amount of wireless resources to be allocated to the i-th wireless beam at time ί based on the total wireless resources Total_Res_All_Beams available across the plurality of wireless beams (determined at step S306) and the fraction B_S_F_i(t) of the total wireless resources to be allocated to the i-th wireless beam at time ί (determined at step S308). In at least one example embodiment, the base station 1 15 computes the amount of wireless resources B_S_i(t) to be allocated to the i-th wireless beam at time ί as shown below in Equation [3].
B_S_i(t) = B_S_F_i(t) * Total_Res_Al Beams [3]
[0051] In Equation [3], Total_Res_All_Beams is the total available resources across the plurality of wireless beams computed at step S306, and B_S_F_i(t) is the fraction of the total wireless resources to be allocated to the i-th wireless beam at time ί as determined at step S308.
[0052] As discussed above, in one example, the fraction B_S_F_i(t) of wireless resources to be allocated to the i-th wireless beam at time ί may be set equal to the fraction B_N_F_i(t) of the total wireless resource needs of the plurality of wireless beams 130, which is attributed to the i-th beam at time i, as determined at step S304 (i.e., B_S_F_i(t) = B_N_F_i(t)). In this example, the amount of wireless resources B_S_i(t) to be allocated to the i-th wireless beam at time ί may be determined based on the total wireless resources Total_Res_All_Beams available across the plurality of wireless beams 130 computed at step S306 and the fraction B_N_F_i(t) of the total wireless resource needs of the plurality of wireless beams 130, which is attributed to the i-th wireless beam at time i, as determined at step S304, as shown below in Equation [4].
B_S_i(t) = B_S_F_i(t) * Total_Res_AlLBeams = B_N_F_i(t) * Total _Res_AlLB earns [4] [0053] According to at least one example embodiment, the wireless resources allocated to the i-th wireless beam by the base station 1 15 are equal to the combined time, frequency, spatial and/or power resources allocated to the i-th wireless beam. For example, if the wireless resources include time, frequency and spatial resources, then the wireless resources allocated to the i-th wireless beam is equal to the sum of the chunks of time, frequency, and spatial resources allocated to the i-th wireless beam. Thus, in this example, the i-th wireless beam's resource supply B_S_i(t) is given by Equation [5] shown below. _S_i(t) = * Fi * S_i(t) = B_S_F_i(t) * Total_Res_AlLBeams
Figure imgf000013_0001
= B_N_F_i(t) * Total_Res_Al Beams [5]
[0054] In Equation [5] . 7} is the amount of time resources allocated to the i-th wireless beam at time i, Fi is the amount of frequency resources allocated to the i-th beam at time i, and S; is the amount of spatial resources allocated to the i-th beam at time i. The summation ∑TFS (Ti*Fi*Si (t)) is the sum of the product of the time resources 7}, the frequency resources Fi and the spatial resources S over all chunks of time, frequency and space. Thus, in this example, the summation ∑TFS represents the sum of the chunks of time, frequency, and spatial resources allocated to the i-th wireless beam at time t.
[0055] Although discussed herein with regard to time, frequency and spatial resources, example embodiments should not be limited to this example. Rather, the wireless resources need not encompass all dimensions of time, frequency and space. Rather, the wireless resources may encompass (e.g. , be in) only one or two dimensions (e.g., time only, frequency only, time and frequency only, etc.).
[0056] If only the time dimension is allocated this implies that the beam, when activated, does not share frequency or spatial resources with any other beam. That is, for example, the activated beam is allocated full use of all frequency and spatial resources for that fraction of time. If only the frequency dimension is allocated, then the activated beam has access to the allocated fraction of frequency exclusively without sharing with any other beam for all time and space. [0057] Returning to FIG. 3, at step S312, the base station 1 15 (e.g. , a scheduler) allocates the amount of wireless resources determined at step S310 to the i-th wireless beam. The base station 1 15 may allocate the wireless resources to the i-th beam in any suitable manner. For example, in a 3GPP-LTE system, the base station 1 15 may allocate physical resources blocks (PRBs) to the i-th wireless beam based on the amount of wireless resources determined at step S310. In a more specific 3GPP-LTE example in which the wireless resources include time and frequency, the base station 1 15 may allocate wireless resources to the i-th wireless beam by allocating PRB blocks to the i-th wireless beam according to the amount of wireless resources B_S_i(t) determined at step S310.
[0058] Transmit power (e.g. , in the uplink and/or downlink) is another dimension for resource allocation. For example, in the PRB example, different PRBs allocated to different beams may have different amount of transmit power allocated thereto for matching with the amount of demand served by the beam. Thus, transmit power at any time may be shared.
[0059] The allocation method discussed with regard to FIG. 3 is dynamic as a function of time ί based on the time varying demand for each beam. Accordingly, the method shown in FIG. 3 may be performed periodically and/ or in response to varying network and/or load conditions. The method shown in FIG. 3 may also be performed dynamically and independently for each beam in the service area, and the wireless resources allocated to each of the beams may be the same or different. Further, according to at least some example embodiments, the wireless resources allocated to a given beam may be different for the downlink (from base station to CPE) and the uplink (from CPE to base station). In this regard, for example, the method shown in FIG. 3 may be performed periodically and independently for each of the uplink and downlink.
