Abstract:
Systems and methodologies are described that effectuate or facilitate multichannel feedback in multichannel wireless communication environments. In accordance with various aspects set forth herein, systems and/or methods are provided that construct a carrier set, classifies a carrier as belonging to the carrier set, utilizes the carrier as representative of all carriers included in the carrier set to measure a channel quality of the carrier, and transmits a CQI based at least in part of the channel quality of the carrier, wherein the broadcast CQI is representative of all carriers included in the carrier set.
Abstract:
The present disclosure relates to reducing control overhead in a wireless communication system. For example, a network entity may determine to transmit data according to a codeword format based on at least one of a transmission time interval (TTI), or a traffic type of the data, or any combination thereof, and configure the data for transmission on a communication channel according to the codeword format. Further, for instance, a user equipment may receive a transmission from a network entity on a downlink communication channel according to a codeword format, and transmit at least one of an acknowledgement (ACK) or a negative acknowledgement (NACK) on an uplink communication channel in response to receiving the transmission from the network entity.

Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an antenna switching capability for the UE that relates to a capability of the UE to switch an antenna for a plurality of bands that are included in a band combination of a set of band combinations supported by the UE, wherein at least two bands of the plurality of bands correspond to a first radio access technology (RAT) and a second RAT respectively. The UE may signal the set of band combinations and the antenna switching capability to a base station. Numerous other aspects are provided.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatuses for power control of transmissions on a physical uplink shared channel (PUSCH) with shortened transmission time intervals (sTTIs). According to certain aspects, a UE may calculate a transmit power for an aperiodic channel state information (A-CSI) report that is independent of an actual number of channel quality indicator (CQI) and precoding matrix indicator (PMI) bits to transmit in the A-CSI report. The UE may then transmit the A-CSI report in accordance with the calculated transmit power.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that a scheduling request (SR) is to be transmitted on a first uplink control channel having a first transmission time interval (TTI) duration and identify that acknowledgment/negative acknowledgment (ACK/NACK) information is scheduled for transmission on a second uplink control channel having a second TTI duration greater than the first TTI duration, where the first uplink control channel and the second uplink control channel overlap in time. The UE may determine that the ACK/NACK information is to be transmitted with the SR on the first uplink control channel based on the overlapping first uplink control channel and second uplink control channel, and may determine resources of the first uplink control channel to be used for transmission of SR and ACK/NACK information. The UE may transmit the SR and the ACK/NACK information on the determined resources.
Abstract:
Methods, systems, and devices for wireless communications are described. The described techniques generally provide for improved reference signal sharing techniques that support low latency communications. In accordance with the described techniques, a base station may transmit, and a user equipment (UE) may receive, signaling configuring the UE to transmit (or receive) a demodulation reference signal (DMRS) in an indicated transmission time interval (TTI) of a plurality of TTIs, where the DMRS is used for demodulation of a data symbol transmitted in a second TTI of the plurality of TTIs. In various examples, the base station or the UE may determine to skip a data transmission in the indicated TTI (e.g., depending on whether the transmission is in the uplink or downlink direction). The base station or the UE may then transmit the DMRS in the indicated TTI and the data symbol in the second TTI.
Abstract:
Apparatus and methods for generation and use of reference signals in a wireless communications system are described. A group-specific reference signal pattern may be generated for provision to a group of UEs or terminals in communication with an eNodeB or base station. The reference signal may be generated based on system parameters. Reference signals may be generated to span multiple contiguous physical resource blocks.
