    摘要: Systems and methodologies are described that facilitate selecting frequency for transmitting control channel format indicator (CCFI) data such to identify a related cell. In one example, the CCFI data can be transmitted in an initial portion of frequency (such as an orthogonal frequency division multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data can be spread across the initial portion of frequency and be shifted to identify the transmitting cell. Additionally, the CCFI data can be scrambled to further identify the cell. The CCFI data can also be utilized to determine structure of subsequent control and/or data channels.

    摘要: Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.

    摘要: Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

    摘要: Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.
