摘要:
The present invention provides a method involving an access network and user equipment that supports communication over an air interface using a plurality of component carriers. The method includes transmitting information indicating that a first component carrier is an anchor carrier for the user equipment. The information is transmitted from the access network in a first field of the first component carrier, which selected from the plurality of component carriers. The method also includes transmitting information indicating that one or more second component carriers is allocated as a non-anchor carrier for the user equipment.

An exemplary method of allocating bandwidth to a call for at least one user includes allocating 10 MHz of the bandwidth for a downlink between a base station and the at least one user. 5 MHz of the bandwidth are allocated for an uplink between the user and the base station. A selected amount of bandwidth is aggregated to the allocated 5 MHz for the uplink. The amount of bandwidth that is aggregated is at least one of an additional 3 MHz band or two additional 1.4 MHz bands.

The present invention provides a method and apparatus for using uplink reference signals for access grant requests. The method includes determining that at least one mobile unit is requesting access to at least one uplink channel based on information indicative of a change in a masking sequence applied to at least one reference signal. Another embodiment of the present invention includes providing a first reference signal modulated by a first masking sequence to indicate a request for access to at least one uplink channel.

The present invention provides a method for transmitting and receiving random access channel messages in an extended range wireless communication system. One embodiment of the method may include accumulating, at a base station, signal energy received during a first portion of a transmission time interval. The method may also include accumulating, at the base station, signal energy received during a second portion of the transmission time interval. The first and second portions are offset from the start or end of the transmission time interval by selected delay intervals. The method may further include detecting the message(s) based on the signal energy accumulated during the first and second portions of the transmission time interval.

The present invention provides a method and apparatus for providing acknowledgment feedback for aggregated downlink component carriers. One embodiment of the method includes determining acknowledgment bits for downlink component carriers that are aggregated to a particular user equipment. Each acknowledgment bit indicates whether a corresponding downlink component carrier was successfully received. This embodiment also includes transmitting symbol constellations representative of the acknowledgment bits in resources of one or more uplink control channels of the uplink component carrier.

Methods of component carrier aggregation are provided. One embodiment of the method includes aggregating, at a base station, one or more first component carriers that are backwards compatible with a first carrier type and one or more second component carriers that are non-backwards compatible with the first carrier type for communication with first user equipment according to a second carrier type used by the second component carrier(s).
摘要:
A method of controlling a load at a wireless communication base station includes determining an indication of a maximum path loss between the base station and any high speed data users currently in a cell served by the base station. A target loading limit for the cell is set based upon the determined indication of the maximum path loss. In disclosed examples, the indication of the maximum path loss corresponds to a distance between a high speed user and a base station. Another factor considered in disclosed examples includes the data rate of such a high speed user.

Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
