Abstract: Aspects of the present disclosure provide various techniques for requesting a system information block (SIB) and providing a SIB response for a user equipment (UE) in a UE-centric wireless communication network. In some aspects of the disclosure, the network may transmit the SIB to the UEs in a broadcast mode or in an on-demand mode.

Abstract: Mobile originated and terminated data transmissions are discussed. Communication devices such as user equipment (UE) can be dynamically configured by a network to send and receive data. When a UE connects to a new network, the network can determine mobility of the UE and/or the network resource allocation granularity. Based at least on the network's determinations, the UE can be configured such that access data having a comparatively long life span is used and reused for multiple data transmissions. In some scenarios, access data can be refreshed after expiration of a period of time. Refresh time can be equal to expected life span of reusable access data. After UE configuration, the UE performs mobile originated and terminated data transmissions according to the configuration. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects provide a subframe for uplink (UL) communication in a frequency-division duplex (FDD) configuration. Control information in the frequency range of the UL communication may include channel quality indicator (CQI) and acknowledgement (ACK) information. The CQI information may be provided prior to a demodulation reference signal (DMRS). The ACK information may be provided subsequent to another DMRS. The CQI information may be time-division multiplexed in a common frequency range as the ACK information. A sounding reference signal (SRS) may be provided as an initial symbol of the subframe. Some CQI information may be provided in two or more separate portions that are each prior to a separate DMRS. Some ACK information may be provided in two or more separate portions that are each subsequent to another separate DMRS.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for transmitting in-band control information in a wireless communication channel. A control and data information coding scheme is utilized to reduce the block error rate (BLER) of in-band control information in various scenarios. A subframe carries coded control information, coded data information, and coded control-data information for reducing the BLER of the in-band control information. The coded control information and coded data information are mix-coded to generate coded control-data information.
