摘要： A method in a wireless communication terminal includes receiving a radio resource allocation having a plurality of sub-carriers that are a subset of available sub-carriers. The available sub-carriers include a DC sub-carrier wherein the DC sub-carrier and all but one edge-most sub-carrier of the plurality of sub-carriers are designated for transmission if the DC sub-carrier is between any two sub-carriers of the allocation, and all of the sub-carriers except the DC sub-carrier are designated for transmission if the DC sub-carrier is not between any two sub-carriers of the allocation.

摘要： A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.

摘要： Disclosed are methods that associate “importance” information with chunks of a media presentation. An end-user device or server uses this information to intelligently manage resources when downloading or rendering the media presentation. Many different types of importance information are used. An editor can tag a chunk as important based on the content of the chunk or may give the chunk a rating, or importance can be inferred from download statistics. In some embodiments, the end-user device determines the importance of a chunk based on observations of the behavior of the device's user. The end-user device can send its locally gathered behavioral observations to a server to enhance that server's demographic information. The server can observe its own download behavior to infer importance. The end-user device may choose to either not download, or to download at a low resolution, those chunks deemed to be unimportant, thus saving bandwidth and battery power.

摘要： A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

摘要： Receiving units will switch between performing a DC bias suppression and not removing the DC distortion at the receiver depending on the amount of DC interference level observed/measured/estimated. Since the overall DC interference is from all uplink transmitters, potentially at different power levels, the amount of DC distortion can be measured based on the difference between the received power level and the expected power level on the DC sub-carrier. Additionally it can be estimated based on the number of active transmitters, their allocation bandwidth, power control target and/or a rough estimate of the DC distortion introduced by each active transmitter and also the distortion introduced by the receiver. Once this distortion level is estimated, a decision is then made whether or not to remove the DC distortion.
摘要翻译：接收单元将在执行直流偏置抑制之间进行切换，而不会根据观测/测量/估计的直流干扰电平的量消除接收机的直流失真。由于整个DC干扰来自所有上行链路发射机，潜在地处于不同的功率电平，所以可以基于DC子载波上的接收功率电平与预期功率电平之间的差异来测量DC失真量。此外，可以基于活动发射机的数量，其分配带宽，功率控制目标和/或由每个有源发射机引入的DC失真的粗略估计以及由接收机引入的失真来估计。一旦估计出该失真水平，则作出是否去除DC失真的决定。

摘要： 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.

摘要： A radio communication unit for a digital communication system is provided in which an input information signal is protected from transmission errors by forward error correction encoding the information signal. In addition, the communication unit enhances subsequent processing of a transmitted form of the information signal by a hard-limiting receiver by inserting a predetermined synchronization sequence into the information signal. Further, a corresponding radio communication unit is provided which includes a hard limiting mechanism for removing the magnitude of each sample in a group of data samples of a signal received from over a radio communication channel. In addition, weighting coefficients of the hard-limited group of data samples for maximum likelihood decoding and diversity combining are generated by comparing the hard-limited group of data samples to a known predetermined synchronization sequence. Finally, estimated information samples are generated, utilizing the weighting coefficients, by maximum-likelihood decoding the group of data samples.
