摘要： Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

摘要： Systems and methodologies are described that facilitate distributing and utilizing interference information in a wireless communication environment. Interference information can be generated by a base station by evaluating uplink conditions, and disparate interference information can be collected from neighbor base station(s). Interference information associated with the base station and the neighbor base station(s) can be transmitted by the base station to access terminal(s). An access terminal that receives that interference information associated with the base station and the neighbor base station(s) can control an operation based at least in part upon the interference information. For example, the access terminal can adjust a transmit power, select a target serving base station for handover, and/or choose a random access channel (RACH) resource to use for random access as a function of the interference information associated with the base station and the neighbor base station(s).

摘要： An access terminal (AT) and a data-optimized cellular communication radio network (RN) negotiate a set of packet sizes for use on a reverse link between the AT and the RN. The negotiated set of packet sizes may differ from the default set of packet sizes defined in an existing standard, such as 1xEV-DO Revisions A and B. The packet sizes in the negotiated set may be tailored to provide a good fit with an application transmitting data on the reverse link, such as a voice encoder of a voice over Internet Protocol (VoIP) application. The AT and the RN communicate using the negotiated set of packet sizes. The packet sizes of the negotiated set may be mapped to the same reverse rate indicator (RRI) channel codewords as are defined in systems operating under the standard. Packing efficiency is thus increased, and higher capacity for delay-sensitive applications is achieved.

摘要： Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.

摘要： Methods and apparatus for selecting a serving sector in a high rate data (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which a sector of an Access Point may send data packets to an Access Terminal. The sector is selected by the Access Terminal to achieve the highest data throughput while maintaining a targeted packet error rate. The Access Terminal employs various methods to evaluate quality metrics of forward and reverse links from and to different sectors, and uses the quality metrics to select the sector to send data packets to the Access Terminal.
