摘要： Support for multiple wireless access technologies at a common terrestrial radio access network is described herein. By way of example, wireless resources can be reserved in a manner that facilitates transmission of control and reference signals to advanced or emerging-technology user terminals (e.g., LTE-A), while mitigating adverse affects on legacy user terminals (e.g., LTE Release 8). As such, information designated for LTE-A terminals can be embedded in predetermined reserved locations, which exploit known standardized behavior of legacy terminals in expecting information at specific locations. Such reserving of resources can occur typically without the legacy terminals being affected, mitigating or avoiding performance degradation for legacy terminals.

摘要： Methods and apparatuses are provided that facilitate puncturing codeblocks in resource blocks for muting or transmitting signals of a disparate technology such that the puncturing similarly impacts the codeblocks. Codeblocks can be mapped in order across frequency in a given data symbol before moving to a next data symbol. In this regard, utilizing data resource elements substantially evenly spaced across frequency and across data symbols in a data resource block for transmitting signals of the disparate technology can substantially equalize impact of the puncturing to related codeblocks. In addition, resources can be allocated to legacy devices, devices with bandwidth, data rate, or quality of service requirements, devices of a certain rank or geometry, etc., based at least in part on the puncturing. Moreover, a modulation and coding scheme can be selected for generating codeblocks based at least in part on the puncturing and its effect on performance.

摘要： Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks are mapped according to a hopping pattern. A first and second pair of physical resource blocks are allocated such that the first pair is associated with a first hopping index pair, whereas the second pair is associated with a second hopping index pair. For this embodiment, the first and second hopping index pairs are inversely symmetrical to each other. A pair of distributed resource blocks is also allocated. An assignment is then scheduled that includes a physical resource allocation and a virtual resource allocation. Aspects for operating a wireless terminal are also disclosed. Here, a communication that includes a resource allocation and a reference signal is received. A minimum resource allocation granularity is ascertained from the communication, and a joint channel estimation is based on the reference signal and is a function of the minimum resource allocation granularity.
