Abstract:
A method and apparatus for control channel transmission and reception is provided herein. In particular, the use of a partitioned and structured control channel is provided that leverages the benefits of common control while maintaining favorable aspects of dedicated control. During operation, control information is distributed over a number of partitions (201). Each Pi is encoded (607) with monotonically non-increasing reliability level. Control information for a given remote unit can be distributed on one or several partitions, from P1 to Pk, where Pk is encoded with the lowest reliability level that can be decodable by the remote unit at an acceptable error rate.
Abstract:
Mobile units in a multicarrier, multidimensional communications system can assess their own channel coherence time attributes (base stations can also access such dynamics for mobile units as well). This information is utilized (either by the mobile unit itself or by an infrastructure component such as a base site) to determine a level of trustworthiness for other channel quality data as might be measured by the mobile unit. Different modulation and coding schemes, along with responsive frequency and time diversity resource allocations, are adaptively selected as a function of this level of trustworthiness.
Abstract:
The present invention provides a method for enabling transparent relaying of data in order to improve the performance of a cellular system. Particularly, relaying on the uplink is performed by fixed entities called Transparent Relays (TR). The base station may allocate one or more TRs to relay the data transmissions associated with a particular CID (e.g., a particular subscriber station) on the uplink.
Abstract:
A method and apparatus are provided for indicating to a communication unit a plurality of modulation and coding schemes (MCSs) to be utilized for communication. During a first MCS is determined for first resource blocks to be sent to a first remote unit or base station, and a second MCS is determined for a second resource block to be sent to the remote unit or base station. A message is transmitted indicating the first and the second MCS and also indicating the first resource blocks and the second resource block. Finally, a first PDU is transmitted to the remote unit or base station at a first time using the first MCS and the first resource blocks and a second PDU is transmitted to the remote unit or base station at the first time using the second MCS and the second resource block.
Abstract:
A method for assigning resources to FS and FNS users, for example, in an OFDM wireless communication system 100, including assigning a first frequency resource to at least one FS user during a time interval, wherein the first frequency resource includes at least two near contiguous sub-carriers, and assigning a second frequency resource to at least one FNS user during the same time interval, the second frequency resource includes for each FNS user at least two non-contiguous sub-carriers, wherein the first and second frequency resources are part of a common frequency channel.
Abstract:
A method for providing a low-feedback scheme for link-quality reporting based on the EESM technique is provided herein. During operation, a node will analyze the current channel conditions and determine a non-liner approximation of the carrier to interference plus noise ratio (CINR). The non-linear approximation is sent to a communication unit as a channel-selectivity report, causing the communication unit to utilize the report to assist with modulation and coding selection.
Abstract:
Un metodo para comunicar estimaciones de canal sobre una pluralidad de subportadores entre un dispositivo transmisor y un dispositivo receptor. El dispositivo transmisor determina una estimacion de canal sobre una pluralidad de subportadores y entonces codifica las estimaciones de canal en al menos una forma de onda de canal codificada. Entonces el dispositivo transmisor transmite al menos una forma de onda de canal codificada al dispositivo receptor.
Abstract:
In order to establish routing to/from a base station within a hybrid-cellular network, each network element is assigned a “class” based on a received signal strength of the base station. Each network element is allowed to choose a network element of lower class for relaying information to the base station.
