摘要： M physical resource blocks PRBs are allocated for localized resource allocation LRA and N−M PRBs are allocated for distributed resource allocation DRA. Each PRB has U subcarriers. Subcarriers of the N PRBs are permuted to result in N subchannels. Serially for each mth one of the M PRBs allocated for LRA, the subcarriers for an mth one of the M PRBs allocated for LRA are punctured from the permuted subchannels. After puncturing, subcarriers of one of the subchannels are filled with subcarriers of all other subchannels which were punctured in the mth one of the M PRBs. The result after puncturing and filling for all M PRBs allocated for LRA is N−M PRBs each having U subcarriers and M PRBs each having U subcarriers. Then there is a wireless communication using at least one of a LRA on the resulting M PRBs or a DRA on the resulting N−M PRBs.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) located in a near field of a base station may receive a beamformed signal from the base station via a three-dimensional (3D) transmission beam. The UE may receive the signal at an antenna panel and detect a signal strength distribution of the signal at the antenna panel. The UE may calculate a signal weight for each portion of the antenna panel and determine beam adjustment information based on the signal weights. The UE may report the beam adjustment information to the base station, and the base station may use the beam adjustment information to adjust the beamwidth of the 3D transmission beam for subsequent transmissions to the UE, which may increase a beamforming gain at the antenna, and improve communication data rate.

摘要： The described techniques relate to improved methods, systems, devices, or apparatuses that support channel state information feedback for semi-open-loop and open-loop schemes. The described techniques provide for a user equipment (UE) to determine an open-loop, semi-open-loop, or closed-loop transmission scheme for deriving channel quality information (CQI). In the case of determined open-loop transmission scheme, the UE may select a transmission scheme corresponding to a time offset value and a precoder cycling granularity value. The UE may determine one or more of a time offset value, a precoder cycling granularity value, and a precoding matrix indicator (PMI) for a channel state information (CSI) report, and generate CQI accordingly. Additionally, the UE may include the determined values in the CSI report to indicate the transmission scheme used for the CQI derivation. Based on the CQI, the base station can then determine the transmission scheme and perform link adaption accordingly.
