    摘要: This invention relates to a catalyst system comprising an activator and one or more heteroatom substituted phenoxide group 3 to 10 transition metal or lanthanide metal compounds wherein the metal is bound to the oxygen of the phenoxide group and provided that: a) if more than one heteroatom substituted phenoxide is present it is not bridged to the other heteroatom substituted phenoxide, b) if the metal is a group 4 metal then the carbon adjacent to the carbon bound to the oxygen of the phenoxide may not be bound to an aldehyde or an ester, c) the carbon ortho to the carbon bound to the oxygen of the phenoxide may not be bound to the C1 carbon in a group represented by the formula: wherein R6 and R7 are independently hydrogen, halogen, a hydrocarbon group, a heterocyclic compound residue, an oxygen containing group, a nitrogen containing group, a boron containing group, an sulfur containing group, a phosphorus containing group, a silicon containing group, a germanium containing group, or a tin containing group, and R1 and R2 may be bonded to each other to form a ring. The activator may be an aluminum alkyl, an alumoxane, a modified alumoxane, a non-coordinating anion, a borane, a borate or a mixture thereof.

    摘要: A method and apparatus for establishing an active set of carriers from a plurality of available carriers for a wireless receiver. The active set of carriers can be determined from the plurality of available carriers for the wireless receiver. An indication of which carriers are in the active set can be sent to the wireless receiver, such as a receiver in a mobile communication device. The receiver or mobile communication device can monitor only those carriers that are listed in the active set of carriers.

    摘要: A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource, for example in a first bitmap (510), and indicates radio resource allocation policy information (520) and indicates a weighting for each assigned wireless communication entity, for example, in a second bitmap (530), to the schedulable wireless communication entities that have been assigned a radio resource.

    摘要: A communication system distributes, in the time domain, acknowledgment transmissions by a group of access terminals sharing a same time domain resource. A position of one or more access terminals in the group of access terminals is determined and each of the one or more access terminals then sends an acknowledgment transmission, such as an acknowledgment or negative acknowledgement, in a time slot that is N time slots after the shared time domain resource, where N is a function of the position of the access terminal in the group of access terminals.

    摘要: A technique for transmitting data in a communication network employing Hybrid Automatic Repeat Request includes a first step 502 of grouping data to be transported into a first and second groups in accordance to a decision parameter, such as data size. A next step 504 concatenates data from the first group and encodes into a multi-user packet. A next step 502 encodes the data into a plurality of data packets. A next step 506 assigns available traffic resources to encoded packets. A next step 506 transmits the encoded packets. A next step 510 reassigns a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.

    摘要: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (710). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), failure handling resources (540), and an ordering pattern (513). If a mobile station fails to decode the shared control channel information element (501) it will access the failure handling resources in order to receive data. The failure handling channel may be persistent in some embodiments, or may be released after the mobile station is once again able to decode the shared control channel information element (501) and thereby share in the shared resource pool allocated to its mobile station group.
