Abstract:
The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.
Abstract:
According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.
Abstract:
A UE may receive, from a base station, a message requesting BSI. The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an exemplary embodiment, the apparatus can receive a packet at a Uu protocol stack of a first user equipment (UE), the packet intended for a base station. In addition, the apparatus can transfer the packet from the Uu protocol stack of the first UE to a PC5 interface protocol stack of the first UE. Furthermore, the apparatus can modify a header of the packet at the PC5 interface protocol stack to identify the packet as relayed uplink traffic intended for the base station from the first UE. Moreover, the apparatus can transmit the packet including the modified header to a second UE for relaying to the base station.
Abstract:
A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may transmit, to a base station, information indicating a capability to communicate with one or more relay UEs. In addition, the apparatus may receive, from the base station, configuration information associated with a discovery procedure for identifying the one or more relay UEs. Further, the apparatus may perform the discovery procedure based on the configuration information.
Abstract:
Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of RS resources.
Abstract:
In a mmW network, a UE and a base station may establish a link using a RACH procedure. A base station may transmit, in a beamformed signal, a message to a UE during a RACH procedure. The message to the UE may include a value indicating a request for beam information. The base station may receive a message from the UE during the RACH procedure that includes a beam information report comprising the beam information.
Abstract:
A user equipment (UE) may communicate with a base station through a first active beam, the first active beam comprising a serving beam. The UE may receive a first reference signal and a second reference signal associated with beam tracking from the base station, where the first reference signal is received through a first beam of a first plurality of beams and the second reference signal is subsequently received through a second beam of a second plurality of beams, and where the beam tracking includes identifying a new beam for communication between the UE and the base station. The UE may communicate with the base station through a second active beam based on at least one of the first reference signal or the second reference signal associated with the beam tracking, the second active beam comprising the new beam.
Abstract:
In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.
Abstract:
Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.
