Method and apparatus for puncturing data regions for signals to minimize data loss

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.

1. A method for wireless communication, comprising:
determining a punctured set of a plurality of data resource elements in one or more data resource blocks for muting or transmitting signals of a disparate technology; allocating a portion of the plurality of data resource elements to in the one or more data resource blocks to one or more devices based at least in part on the punctured set of the plurality of data resource elements, wherein the allocating the portion of data resource elements includes allocating resources to devices that cannot process the disparate signals based on avoiding data resource elements that are associated with the punctured set; selecting a modulation and coding scheme (MCS) for encoding data over the portion of the plurality of data resource elements based at least in part on the punctured set, wherein the selecting the MCS includes determining a codeblock of a plurality of codeblocks mapped over the portion of the plurality of data resource elements that includes a largest portion of the punctured set and computing an expected performance of the one or more codeblocks, wherein the computing the expected performance includes computing an expected performance of said determined codeblock when being punctured, and wherein the selecting the MCS is based further at least in part on the expected performance; encoding the data for the one or more devices into the one or more codeblocks for transmission over the portion of the plurality of data resource elements using the selected MCS; and puncturing the one or more codeblocks by replacing data values in codeblocks corresponding to the resource elements with disparate values according to the punctured set, wherein the signals of a disparate technology comprise reference signals.
