Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.

Abstract: The apparatus in some aspects may be a wireless device configured to operate a first transceiver in a first connected mode with a first radio access network (RAN) and a second transceiver in a second connected mode with a second RAN. The apparatus may further be configured to transmit a first communication via the first transceiver and obtain, based on a second communication via the second transceiver, an indication of a cancellation of one or more symbols for the first communication via the first transceiver. The apparatus may also be configured to refrain from transmitting, based on the indication, a remaining portion of the first communication via a set of symbols including the one or more symbols.

Abstract: A method for wireless communication at a wireless device is disclosed herein. The method includes selecting a wideband precoder for a first set of antennas and a second set of antennas based on at least one matrix, where a number of the first set of antennas and the second set of antennas is greater than a maximum number of supported layers. The method includes calculating, based on the selected wideband precoder, a first set of performance metrics for the first set of antennas and a second set of performance metrics for the second set of antennas. The method includes combining the first set of performance metrics for the first set of antennas and the second set of performance metrics for the second set of antennas based on the calculation.

Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Abstract: Certain aspects of the present disclosure provide techniques for indicating capability of a user equipment (UE) to support multiple sounding reference signals (SRSs) with a single subframe, with at least one of frequency hopping, different bandwidths, or antenna switching for the multiple SRSs in the same subframe.

Abstract: To correct for frequency shift errors, one or more frequency tracking loops may be implemented on a broadcast channel and/or dedicated channel to correct for frequency errors. A coarse loop, fine loop, or combination thereof may be used to allow accurate correction for even large frequency errors.

Abstract: Methods and apparatus for wireless communication for improving handover between a network and a user equipment (UE) when a measurement report is received. Aspects of the methods and apparatus relate to determining the quality of a serving cell associated with a fast handover performance threshold. When the fast handover performance threshold is breached, the UE may transmit a measurement report requesting a handover to a target cell. Upon requesting a handover to a target cell when the fast handover performance threshold is breached, the UE receives a handover trigger allowing handover to a target cell.

Abstract: In a TD-SCDMA user equipment (UE) with multiple receive chains, receive diversity may be implemented where multiple receive chains may simultaneously activate to receive downlink signals. Receive diversity may be enabled when single chain reception provides undesired results and when receive diversity will not impact power consumption too much. A state machine controls receive diversity operation based on operating conditions such as control channel activity, successful control channel decoding, signal-to-interference ratio, and other factors.
