Description
- This application claims the benefit of and hereby incorporates by reference U.S. Provisional Patent Application Ser. No. 61/821,635, filed May 9, 2013, with an attorney docket number P56618Z.
- Users of wireless and mobile networking technologies are increasingly using their mobile devices to send and receive data as well as communicate. With increased data communications on wireless networks the strain on the limited bandwidth and system resources that are available for wireless telecommunications is also increasing. To handle the increasing amount of wireless services to an increasing numbers of users, an efficient use of the available radio network resources has become important.
- In homogeneous networks, the transmission station, also referred to as a macro node, can provide basic wireless coverage to mobile devices within a defined geographic region, typically referred to as a cell. Heterogeneous networks (HetNets) were introduced to handle the increased traffic loads on the macro nodes due to increased usage and functionality of mobile devices. HetNets can include a layer of planned high power macro nodes (or macro-enhanced Node Bs) overlaid with layers of lower power nodes (micro-nodes, pico-nodes, femto-nodes, home-eNBs, relay stations, etc.) that can be deployed in a less well planned or even entirely uncoordinated manner within the coverage area of the macro nodes. The macro nodes can be used for basic coverage, and the low power nodes can be used to fill coverage holes, to improve capacity in hot-zones or at the boundaries between the macro nodes' coverage areas, and improve indoor coverage where building structures impede signal transmission.
- Spectrum efficiency is the optimized use of spectrum or bandwidth so that the maximum amount of data can be transmitted with the fewest transmission errors. In a cellular network, spectrum efficiency measures how efficiently a limited frequency spectrum is utilized, such as the maximum number of users per cell that can be provided while maintaining an acceptable quality of service (QoS). For small nodes in a HetNet, enabling higher modulation orders in the small-node environments can enable greater spectral efficiency.

It should also be understood that terminology employed herein is used for the purpose of describing particular examples only and is not intended to be limiting.

- Mobile devices are increasingly equipped with multiple radio access technologies (RATs). The mobile devices can be configured to connect to and choose among different access networks provided by the RATs. In homogeneous networks, the base stations or macro nodes can provide basic wireless coverage to mobile devices in an area covered by the node. HetNets can include a layer of macro nodes or macro-eNBs overlaid with layers of small cells, also referred to as low power cells, low power nodes or small nodes, such as micro-nodes, pico-nodes, femto-nodes, home-eNBs, relay stations, etc. In addition, other RATs, such as Institute of Electronics and Electrical Engineers (IEEE) 802.11 configured access points (APs) can be interspersed with the low power nodes.
- The macro nodes can be used for basic coverage and the small nodes or low power nodes can be used to fill coverage holes, to improve capacity in hot-zones or at the boundaries between the macro nodes' coverage areas, and improve indoor coverage where building structures impede signal transmission. Small nodes, such as femto nodes, can also be indoor nodes in houses, apartments, offices, or other indoor locations. In one embodiment, small nodes can support closed subscriber group (CSG) functionality. Small nodes, such as pico cells, can be used for coverage in halls and airports. Small nodes can also be used as outdoor nodes. Small nodes can also be used at lower heights compared to macro nodes.
FIG. 1 depicts a multi-RAT HetNet with amacro-cell 110 and amacro-node 120 overlaided with layers of lower power or small nodes including micro-nodes 130, pico-nodes 140, femto-nodes 150, and WiFi access points (APs) 160. - High demand for increased throughput by UEs can be satisfied by deploying a cluster of small nodes to provide an acceptable quality of service (QoS) for the UEs. In one embodiment, dense clusterization of small nodes can be used at hotspots to provide closer serving nodes to more UEs for better network capacity. However, as the number of small nodes deployed in a given area increases, the inter-small node interference also increase. As inter-small node interference reaches a threshold limit, there is an upper bound constraint on the number of small nodes to be deployed in a hotspot area. Traditionally, the disadvantage of the high density deployment or clusterization of small nodes is the level of inter-small node interference, e.g. the level of interference that occurs between multiple small nodes in a dense area. The inter-small node interference decreases the signal to noise ratio (SNR) and/or the signal to interference plus noise ratio (SINR) between UEs and small nodes, resulting in lower or decreased UE throughput. To maintain an optimum density of small node deployments, inter-small node interference is minimized while UE throughput is maximized.
- In one embodiment, small areas provide higher SNR which allows the use of higher modulation and coding schemes (MCS), such as 64 quadrature amplitude modulation (QAM), 128 QAM, or 256 QAM. As the distance or separation between small nodes and UEs decrease, propagation losses and interference levels decrease and better channel conditions and SNR or SINR are maintained between the UEs and the small nodes. In one embodiment, interference mitigation techniques can be used to improve or boost the SNR and/or SINR of a UE so that the UEs can use higher modulation schemes with an acceptable error rate. In one embodiment, higher performance for small nodes, such as high throughput and low interference, can be achieved by using higher order modulation schemes, such as 256 QAM. When higher order modulations are used, signal imperfections, such as signal interference, at the UE and small node are reduced because the distance between constellation points are shorter.
- In one embodiment, the optimum number of small nodes per hotspot is determined to achieve the highest user average throughput with minimal inter-small node interference. The optimum number of small nodes can be determined by evaluating the feasibility of high modulation order schemes, such as 256 QAM. In one embodiment, the small nodes can be outdoor small nodes. In another embodiment, UEs can operate in a high SINR region to use a 256 QAM. In one embodiment, multiple UEs can be clustered in an indoor hotspot environment and are served by small nodes. In another embodiment, when a small node varies channels the macro node can be configured to vary channels as well. In one embodiment, inter-frequency variation can be used for the macro nodes and small nodes, where different frequencies are used for the macro nodes and the small nodes.

The method may further comprise the operation of transmitting data in the TBS from the small node to a UE using the MCS, as inblock 240. - In one embodiment, the method further comprises: assigning a MCS index of 29 for a modulation order of 8 and a coding rate of 0.7017; assigning a MCS index of 30 for a modulation order of 8 and a coding rate of 0.7283; assigning a MCS index of 31 for a modulation order of 8 and a coding rate of 0.755; assigning a MCS index of 32 for a modulation order of 8 and a coding rate of 0.7817; assigning a MCS index of 33 for a modulation order of 8 and a coding rate of 0.8083; assigning a MCS index of 34 for a modulation order of 8 and a coding rate of 0.8217; assigning a MCS index of 35 for a modulation order of 8 and a coding rate of 0.8483; assigning a MCS index of 36 for a modulation order of 8 and a coding rate of 0.875; assigning a MCS index of 37 for a modulation order of 8 and a coding rate of 0.915; and/or assigning a MCS index of 38 for a modulation order of 8 and a coding rate of 0.9417.

The table inFIG. 10 further illustrates that most of the original gain under ideal condition will diminish when both the TX EVM and the RX EVM are considered. -
FIG. 11 illustrates a cluster of a plurality of small nodes for a system level simulation (SLS). In one embodiment, for different impairments the throughput gains will vary. In one example, an inter-frequency mode is used in which a small node operates at 3.5 GHz and an reference signal received quality (RSRQ) based UE association rule is used, where a full load and zero cell-range expansion (CRE) are used. Additionally in one the example, SLS evaluation parameters are used for the SLS, such as the parameters shown inFIG. 20 . In one embodiment, when an RSRQ association rule is used for the network as inFIG. 11 , 50.36% of the UEs are associated with the macro cell and 49.64% of the UEs are associated with the four small nodes. In one embodiment, a 256 QAM with throughput gains with TX EVM is used. -
FIG. 12 depicts a post-processing SINR distribution of small-cell UEs with different lambdas (λ) at 4% TX EVM. In one embodiment, a 4% TX EVM is used for small nodes and an 8% TX EVM is used for macro cells. In another embodiment, a non-full buffer traffic model (FTP model-1) is used with arrival rates of λ, where the different values of λ correspond to a range of cell resource utilization (RU). -
FIG. 12 also depicts the CDF of the average post-processing SINR of the small-cell UEs for different λ, e.g. traffic rates.FIG. 12 illustrates that as SINR charging data function (CDF) decreases λ increases because the higher loading rate the more transmission and hence more interference there is. For example, when λ is 4, 68% of the PDSCH transmission post SINR has an SINR above 20 decibels.FIG. 12 also illustrates that the post-processing SINR is upper bounded by 28 dB because of the 4% TX EVM. -
FIG. 13 illustrates the average UE throughputs as a function of a file transfer protocol (FTP) model-1 arrival rate.FIG. 13 depicts the average UE throughput for the UEs using small nodes, the UEs using macro nodes, and all the UEs.FIG. 13 also depicts the potential 256 QAM gains, where small nodes employ both a 64 QAM and a 256 QAM.FIG. 13 also illustrates that the average UE throughput decreases with 2. In one example, the average UE throughput decrease because as λ increases the cells start to transmit more data causing more interference to the neighboring UEs, e.g. lowering the SINR per UE. In another example, the average UE throughput decreases because the cells get congested serving higher traffic as λ increases, e.g. longer periods to serve each UE.FIG. 13 depicts that for maximum modulation orders in small nodes, a 256 QAM achieves higher UE throughput for selected λ values. For example, when is 12 (e.g. the small node RU is 23.89%), the throughput of a UE using a small node increases by 10.1% due to employing 256 QAM modulation order. In another example, for all the UEs, both UEs using macro nodes and UEs using small nodes, where λ is 12, the average all UEs gain is 10.03%, and the average RU of all the cells is 37.32%. - The table in
FIG. 14 shows the throughput values achieved by the UEs using small nodes with 256 QAM modulations at different distribution points, e.g. 5%, 50%, 95%, and average (AVG).FIG. 14 also shows the percentage gains of a 256 QAM compared to a 64 QAM.

FIG. 16 illustrates 256 QAM throughput gains for both TX EVM and RX EVM.FIG. 16 also shows the potential gains of a 256 QAM with receiver impairments.

InFIG. 16 , RX EVM is set to 4% for a starting value to show the potential gains of the 256 QAM.FIG. 16 also depicts the average UE throughputs values, similar toFIG. 13 . In contrast to the average throughput values when using the TX EVM inFIG. 13 , the throughput values are smaller for when using both TX EVM and RX EVM as inFIG. 16 . The throughput values inFIG. 16 may be smaller because of the impact of the RX EVM. - The table in
FIG. 17 shows the gains and RU for UEs using small nodes with TX EVM and RX EVM. The table inFIG. 18 shows the gains and RU for the UEs using small nodes and macro nodes for the TX EVM and RX EVM cases. Compared to the tables inFIGS. 14 and 15 , the absolute values of the UE throughput gains are lower in the tables inFIGS. 17 and 18 . In one embodiment, because of the 4% RX EVM, the UE throughput gains of the 256 QAM are lower inFIGS. 17 and 18 than in the tables inFIGS. 14 and 15 . The table inFIG. 17 also shows that the average throughput gains of the UEs using the small nodes (small-cell UEs) range from 5.97% to 8.59%. The table inFIG. 18 shows that the average throughput gains of all the UEs range from 4.38% to 7.52%. - The table in
