  • Publication number: 20210377929
    Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, and transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.

  • Publication number: 20210376984
    Abstract: Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.
