摘要:
Embodiments of the present invention provide methods and apparatus for wireless communication using codeword with high-rate codes. Other embodiments may be described and claimed.
摘要:
In a base station using spatial division multiple access communications, different length transmissions directed from a base station to different multiple mobile devices substantially simultaneously may have their start times adjusted so that the transmissions end at approximately the same time. The mobile devices may then respond during a response period with acknowledgments at approximately the same time. Thus all the acknowledgments may be received within the same time period from the end of the transmissions, reducing the likelihood of missed acknowledgments in responses to the shorter transmissions.
摘要:
A communication device, comprising: a receiver responsive to a wireless communication signal received from a remote communication device, the receiver being configured to: generate a large matrix codebook based, at least in part, on one or more perceived characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal, the receiver being further configured to: select a suitable small matrix codebook based at least in part on the one or more characteristics of the received signal; and combine the small codebook with one or more additional codewords to generate the large matrix codebook, the one or more additional codewords comprising fine matrix codewords.
摘要:
Embodiments of multiple input multiple output wireless communication systems, associated methods and data structures are generally described herein.
摘要:
Embodiments of the present invention provide for computing spatial covariances of intersymbol interference (ISI) and using the computed spatial covariances for ISI mitigation. Other embodiments may be described and claimed.
摘要:
Embodiments of a base station and method for resource allocation using localized and distributed resource blocks are generally described herein. The base station comprises processing circuitry to allocate localized resources to user stations based on receipt of channel quality information received from the user stations and to allocate distributed resource to user stations based on non-receipt of channel quality information. The base station also comprises physical layer circuitry to transmit control information on a physical channel to indicate the resources that are allocated to each scheduled user station.
摘要:
When initiating SDMA training sequences, a base station may poll multiple mobile devices with the same multicast training poll, and the polled mobile stations may respond separately at different times based on an assigned delay period for each mobile station.
