摘要： Apparatus and methods for interlacing communications in random access control channels of an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system are described. A wireless communication device communicating over distinct OFDMA control channels to multiple serving sectors may operate under link limited conditions. The wireless communication device can interlace the communications between the multiple serving sectors. The wireless communication device can interlace the control channel communications in a number of interlaces equal to the number of distinct control channels over which communications are scheduled. In another embodiment , the wireless communication device divide the multiple scheduled control channel communications into two or more sets and can interlace the sets. In another embodiment, the wireless communication device can reserve a first interlace for control channel communications with the serving sector and can time multiplex the remaining control channel communications on a second interlace.

摘要： Systems and methodologies are described that facilitate dynamically scheduling frequency sets for reuse by user devices to reduce inter-cell interference by evaluating an overall scheduling metric for each user device in a wireless communication region. The overall scheduling metric can be evaluated by determining a fairness metric for each user device in a wireless communication region, an overall channel peak desirabality metric for each user device, and a channel delay desirability metric for each user device. The overall scheduling metric can be the function of the fairness metric and one or more of the overall channel peak desirability metric and the channel delay desirability metric. A user device with a highest overall scheduling metric score for a given round of dynamic scheduling can be awarded a frequency set.

摘要： Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.

摘要： To transmit signaling, a base station obtains signaling (e.g., ACKs) for a group of channels used for data transmission and selected from a set of channels having constraints on usage 810). The base station compresses the signaling based on the channel constraints and obtains at least one message (832) . If multiple messages are to be sent, then the assigned channels are partitioned into multiple subgroups, and the signaling for the channels in each subgroup is compressed to obtain a message for that subgroup (820,822) . Each message is encoded at a spectral efficiency and transmitted at a power level selected for the message (824,828) . A CRC value is appended to the message(s) for error detection (826) . To receive the signaling, a terminal checks a received message with the appended CRC, decodes the message if the CRC passes, decompresses the decoded message based on the channel constraints, and extracts the signaling for an assigned channel.
