| 20090175162 | Method of OFDM communication using superposition coding - Improvements are provided in an OFDM network that uses superposition coding. A broadcast signal and e.g. a unicast signal are each subjected to OFDM modulation including processing by an IDFT, combined, and transmitted using non-orthogonal transmission resources. In one approach, the respective signals are combined after instead of before the IDFT processing. In specific examples, a respective cyclic prefix is appended to each signal after the IDFT processing but before the respective signals are combined. In another approach, a broadcast pilot signal and e.g. a unicast pilot signal are transmitted concurrently with the broadcast and unicast information signals. The pilot signals are transmitted using the same time and subcarrier resources, but are mad e more distinguishable by combining each with a respective scrambling or spreading code. In specific examples, embodiments, the unicast pilot signal is used for estimating the data rate for transmission of further unicast information signals. | 07-09-2009 |
| 20100009717 | Wireless communication system and method of joint beamforming wireless communication - A wireless communication system and joint beamforming method across multiple base stations for communicating with mobile stations. The wireless communication system communication system includes base stations and mobile stations. At least one of the base stations includes a joint beamformer controlling beamforming for the base stations. Each of the mobile stations receive information from the base stations, maintain a multiple-input and multiple-output active set (MAS) of base stations, and provide precoder weights to each of the base stations included in the MAS. The joint beamformer calculates joint beamforming weights for controlling communications between the base stations and mobile stations. | 01-14-2010 |
| 20110105033 | Methods for assigning scrambling codes and reducing interference in telecommunications networks - Example methods use secondary scrambling codes in telecommunications networks. The secondary scrambling codes are assigned to mobile stations and channels used by mobile stations that are not adversely affected by the use of secondary scrambling codes. By assigning secondary scrambling codes additional users can utilize telecommunications networks with unique scrambling codes without reducing quality of service or increasing resource consumption. Example methods also reduce interference between mobile stations in the telecommunications networks. | 05-05-2011 |
| 20110136484 | USER ADMISSION, POWER, RATE AND MOBILITY CONTROL METHOD FOR RELAY COMMUNICATION SYSTEMS - In one embodiment, a request is sent to a relay node (RN) requesting the RN to perform a signal measurement operation. The request includes an indication to measure a signal strength of a link between the RN and a user equipment (UE). A signal measurement value is received from relay node, a determination on whether to associate the UE with the RN is made based on the signal measurement value. | 06-09-2011 |
| 20110176433 | Method of controlling resource usage in communication systems - In one embodiment, the method includes receiving, at the communication node, resource usage price information. The resource usage price information characterizes a cost associated with the communication node using a resource. The communication node determines an amount of the resource to use based on the received resource usage price information. | 07-21-2011 |
| 20110176453 | Method of configuring interfaces between a plurality of communication nodes - One embodiment includes monitoring, for each communication node, at least one factor of interest and a plurality of potential influencing factors associated with the factor of interest. The factor of interest characterizes an operating condition of the communication node, and the plurality of potential influencing factors each have a potential influence on the operating condition. For each factor of interest for each communication node, a predictor coefficient for one or more of the potential influencing factors associated with the factor of interest is determined. The predictor coefficient indicates a predicted level of influence the potential influencing factor has on the factor of interest. For each communication node, interfaces are configured between the communication node and other communication nodes based on the determined predictor coefficients. | 07-21-2011 |
| 20110238552 | Method And Apparatus To Facilitate Dynamic Resource Access In Wireless Networks - To address the need to fairly allocate resources to a number of competing and heterogeneous consumers, embodiments such as those depicted in diagram | 09-29-2011 |
| 20120108246 | METHOD AND APPARATUS FOR OPTIMIZING THE LOCATION OF HETEROGENEOUS UNDERLAID EVOLVED NODE-Bs - In one embodiment, mobile device traffic information and signal strength information associated with a geographical region are obtained. A plurality of candidate locations are determined based on the traffic information and the signal strength information, capacity values for each of the candidate locations are determined, and a candidate location is selected, from among the plurality of candidate locations, as a placement locations based on the capacity values. | 05-03-2012 |
