Abstract:
The invention provides a method for operating a hybrid automatic repeat request communication system wherein it is determined whether a receiver can process a data packet, and a self-decode request associated with the data packet is sent based on the determination.
Abstract:
The invention relates to a group application for group formation and management, in particular in a wireless environment. The present invention provides a group application in which a membership list of a group is lept updated automatically by communictions between the group application of the group. the group application handles all the complexity involved in setting up a group and maintaining a membership list for the group, without user intervention. Advantageously, the group appliction is implemented as a software agent. The invention also relates to an electronic device having a group application or software agent of the invention loaded therein.
Abstract:
A communication system (100) that includes a base unit (101) and a subscriber unit (e.g., 103) employs a method (400) and apparatus (101) for mitigating interference (135) therein. The base unit (101) receives an uplink communication signal from the subscriber unit (103) at an uplink frequency and conveys a downlink communication signal to the subscriber unit (103) at a downlink frequency. Upon receiving (403) an uplink communication signal from the subscriber unit (103), the base unit (101) determines (405) a quality metric for the uplink frequency. When the quality metric is below a quality threshold (407), the base unit (101) and the subscriber unit (103) transfer (415) the communication signal to an alternate uplink frequency, while the downlink frequency remains unchanged.
Abstract:
Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.
Abstract:
A mobile station (402) selects (1802) a preferred cell site for transmitting a frame of data to be sent subsequently to the mobile station. A base station (602) of the preferred cell site schedules (1804) a transmission of the frame of data, wherein parameters for the transmission are determined by the base station from recently-measured channel and interference information. Thereafter, the base station sends (1806) the frame of data from the preferred cell site; and an active set of base stations associated with the mobile station at ones of a plurality of cell sites synchronize (1808) their data queues to reflect the transmission of the frame of data.
