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: Multicasting resource allocation information per aggregation level is enabled. A device allocates resources to UEs according to aggregation level. At each level, a control message includes a bitmap, where each bit corresponds to a different resource, an array, and an ID field for dynamic mapping to the bitmap. The placement order value of an ID in the field is stored at locations in the array. The index value for those locations in the array identifies which asserted bits in the bitmap correspond to the resource allocation for a UE at the level. The control message is multicast to the UEs specified at the aggregation level. The bitmap may have the same length at each level, or have reducing length at lower levels with the removal of bits already asserted at higher levels. The UE reconstructs the bitmap from the higher level bitmaps and the bitmap for the current level.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an eNB. The eNB informs UE(s) of a change in at least one of a first configuration for transmission of ACKs/NACKs by the UE(s) for DL transmissions received by the UE(s) or a second configuration for reception of ACKs/NACKs by the UE(s) for UL transmissions sent by the UE(s). The eNB indicates to the UE(s) one or more resources in which the UE(s) is to transmit the ACKs/NACKs for the received DL transmissions or is to receive the ACKs/NACKs for sent UL transmissions. The eNB indicates to the UE(s) a subset of the DL transmissions to the UE(s) for which the UE(s) is to transmit the ACKs/NACKs or a subset of the UL transmissions by the UE(s) for which the UE(s) is to receive the ACKs/NACKs.

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.
