Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. A transmitting apparatus receives a packet at a MAC layer object and generates a first MAC layer output and at least one duplicate MAC layer output based on the received packet. The MAC layer output and duplicate MAC layer output are fed to a PHY layer object. The PHY layer object can transmit first PHY layer information in a first TTI and begin transmitting a second, duplicate PHY layer information in a second, consecutive TTI following the first TTI. The receiving apparatus receives first information in a first TTI and receives duplicate information in a second, consecutive TTI following the first TTI. The receiving apparatus attempts to early decode the information in the first TTI, and when unsuccessful, attempts to decode the information in the second TTI.
Abstract:
Aspects of the present disclosure provide techniques and apparatus for assisted cell acquisition by a wireless node, such as a smartphone, enhanced machine type communications (eMTC) device, and/or wearable. In one aspect, a method is provided which may be performed by the wireless node. The method generally includes obtaining assistance information for use in performing a cell search and transmitting the assistance information to another wireless node. The other wireless node can be an eMTC device such as a wearable. The other wireless node can receive the assistance information for use in performing a cell search and perform a cell search using the assistance information. The techniques for assisted cell search for low cost devices can lead to a faster cell acquisition time may, reduced power consumption, and longer battery life.
Abstract:
Aspects are described for modifying transmission of control channel signaling during wireless communication. The described aspects include detecting a communication condition corresponding to signaling information transmitted on a Dedicated Channel (DCH); determining whether a Dedicated Physical Data Channel (DPDCH) is transmitted based on detecting the communication condition; and performing a Dedicated Physical Control Channel (DPCCH) gating pattern in response to the determination that the DPDCH is not transmitted, wherein performing the DPCCH gating pattern includes intermittently transmitting the DPCCH when one or more signaling radio bearers (SRBs) are not being transmitted.
Abstract:
Aspects described herein relate to selecting a rank for wireless communications using multiple transmit antenna layers. A first effective throughput achievable using a first rank and based at least in part on a first block error rate (BLER) associated with the first rank can be estimated along with a second effective throughput achievable using a second rank and based at least in part on a second BLER associated with the second rank. The first rank or second rank is selected to be used for transmitting communications over multiple transmit antenna layers based at least in part on comparing the first effective throughput to the second effective throughput, and the selection can be indicated to a transmitting entity from which the communications over the multiple transmit antenna layers are received.

The present disclosure presents a method and an apparatus for reducing battery consumption at a user equipment (UE). For example, the method may include configuring a 10 ms transmission mode on an uplink (UL) channel at the UE, indicating configuration of the 10 ms transmission mode to a base station in communication with the UE, compressing a 20 ms transmission associated with a 20 ms transmission time interval (TTI) into a 10 ms compressed transmission, transmitting the 10 ms compressed transmission during a first 10 ms of the 20 ms TTI, and performing a discontinuous transmission (DTX) of the UL channel during a second 10 ms of the 20 ms TTI. As such, reduced battery consumption at a UE may be achieved.

Abstract:
Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an uplink MIMO transmission (e.g., a rank 2 transmission) may be established, wherein a primary stream transport block size (TBS) is determined in accordance with a received scheduling grant, and a modulation scheme for the transmission is determined in accordance with the TBS. Further, a predetermined spreading factor, such as a 2×SF2+2×SF4 spreading factor, may be configured for both uplink streams, independent of the TBS. Finally, the uplink MIMO transmission may be made in accordance with the determined TBS, modulation scheme, and spreading factor. In some examples, if the primary stream TBS or a determined secondary stream TBS is less than a minimum threshold TBS, the transmission may be reconfigured as a rank 1 transmission.

The present disclosure presents example methods and apparatuses for improved cell searching in a wireless communications environment. For example, the disclosure presents example methods of wireless communication in a multiflow environment, which may include establishing a first flow between a serving radio network controller (S-RNC) and a first network entity, wherein the S-RNC controls the first network entity. Such example methods may also include establishing a second flow between the S-RNC and a second network entity. Furthermore, such example methods may include transmitting data to a user equipment (UE) via both the first flow and the second flow.
