Abstract: Aspects of the disclosure relate to the generation of channel state reports. A base station transmits a reference signal over a plurality of ports. A user equipment (UE) receives the reference signal and measure amplitudes of the reference signal over a plurality of ports. A first subgroup of the plurality of ports and a second subgroup of the plurality of ports are determined. In embodiments, the port groupings may be determined by the base station, which transmits an identification of the groupings to the user equipment. Alternatively, the UE may determine the port groupings. After determining the port groupings, the UE separately quantizes and normalizes the measured amplitude values in each port grouping. The UE may also separately quantize and normalize the phase measurements in each port groups. The UE generates a channel state report based on the normalized and quantized amplitude and phase values.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit an encoded transmission via a broadcast to multiple user equipment (UE). Subsequently, the multiple UEs may transmit assistance information to the base station based on attempting to decode the broadcasted encoded transmission. If the decoding is unsuccessful for at least one UE, the base station may then transmit an additional encoded transmission via a unicast or multicast message to the UEs that were unsuccessful. Additionally, the base station may transmit configuration information for the multiple UEs to receive the encoded transmissions and to transmit the assistance information. For example, the configuration information may include portion information for how long the encoded transmission is transmitted via the broadcast, via the unicast, when to transmit the assistance information, etc. In some cases, the configuration information may be based on UE metrics of the multiple UEs.

Abstract: Aspects of the disclosure relate to transmitting, from a user equipment (UE) to a base station, information indicative of a multicast session that the UE is interested in accessing; transmitting information indicating that a first beam of a plurality of beams is a preferred beam for receiving multicast data associated with the multicast session; receiving, from the base station, a list of at least one beam of the plurality of beams associated with the multicast session; and receiving, from the base station using a beam from the list, multicast data associated with the multicast session. Other aspects, embodiments, and features are also claimed and described.
