摘要： Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected, yielded, etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance, the at least one time domain component can be punctured, time-shifted, and so forth. Further, UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover, a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further, the UE can estimate a channel based upon the UE-RSs.

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： Techniques for supporting channel measurement and reporting in a wireless communication system are described. In one design, a cell transmits a cell-specific reference signal (CRS) used for channel estimation and coherent demodulation and a channel spatial information reference signal (CSI-RS) used for channel measurement and channel feedback reporting. The cell may transmit the CSI-RS less frequently than the CRS, or from more antenna ports than the CRS, or on fewer resource elements than the CRS, or a combination thereof. In one design, a user equipment (UE) determines at least one bandwidth part configured for the UE, with each bandwidth part covering at least one subband. The UE receives the CRS and CSI-RS from the cell, determines channel feedback information for the at least one bandwidth part based on the CSI-RS, sends the channel feedback information to the cell, and receives data transmitted by the cell based on the channel feedback information.
