Abstract: A method for receiving downlink data in a wireless communication system is provided. A user equipment receives downlink control information via a downlink control channel in a subframe. The downlink control information includes reference signal (RS) information and physical downlink shared channel (PDSCH) information. The RS information indicates transmission antenna ports, a scrambling identity and a number of transmission layers. The user equipment receives a RS for demodulating a PDSCH based on the RS information in the subframe. The RS is generated based on the scrambling identity. The user equipment receives downlink data via the PDSCH in the subframe. Resource element (RE) mapping information on REs assigned for the PDSCH is determined based on the PDSCH information.

Abstract: A method for transmitting ACK/NACK (Acknowledge/Negative ACK) information at a user equipment in a wireless communication system, and a user equipment therefore are discussed. The method according to one embodiment includes generating an ACK/NACK payload for a plurality of carriers, the ACK/NACK payload including a plurality of concatenated ACK/NACK sets. Each ACK/NACK set is associated with a respective one of the plurality of carriers and has one or more ACK/NACK bits. The method further includes transmitting the ACK/NACK payload through a PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). The ACK/NACK payload includes an ACK/NACK bit for a semi-persistent scheduled downlink signal. The ACK/NACK bit for the semi-persistent scheduled downlink signal is positioned at an end of a corresponding ACK/NACK set, not an end of the ACK/NACK payload.

Abstract: A method and an apparatus are provided for determining whether an enhanced physical downlink control channel (ePDCCH) transmission exists for a user equipment (UE) in a subframe. The UE receives a transmission on physical downlink control channel (PDCCH) resources of the subframe. Downlink control information (DCI) is extracted from the PDCCH resources. The DCI includes at least one bit indicating whether the ePDCCH transmission exists for the UE in the subframe. The UE determines whether the ePDCCH transmission exists using the at least one bit. Additional symbols of the subframe are buffered and decoded when the ePDCCH transmission exists.

Abstract: Techniques for providing hybrid communications to devices on vehicles include using a selected modulation scheme on a forward link to deliver data (that is intended to be received by an on-board device) onto a vehicle, and using a reverse link in a different frequency band to send reverse data from the vehicle. Based on the reverse data, a subsequent pre-defined modulation scheme for a subsequent forward transmission is selected from a plurality of modulation schemes corresponding to a plurality of performance levels of data delivery. The selections may be based on a current geo-spatial location of the vehicle, a type of data, and/or on one or more other dynamic conditions. The forward data may be multiplexed and/or multicast. Thus, adaptive modulation is achieved in a hybrid communications system in which the forward link and the reverse link to the vehicle are supported by different wireless communication bands.

One method includes determining, for example by an information receiver, a unique connection identity for an off-band connection with an information provider. The unique connection identity may be based on information related to a user plane connection with the information provider. The method may further include storing the unique connection identity, receiving radio access network information and synchronization information from the information provider, and synchronizing at least part of the radio access information with at least part of information sent in the user plane connection, using the synchronization information.

Abstract: A method of transmitting data allows flow control information to be transmitted with the user data over a synchronous bus. A channel is defined, identifying the source and at least one sink, and this includes the definition of a transport profile, indicating a flow control requirement for the data. Data is then transmitted from the source over the bus in at least one data time slot (30) and, if indicated by the transport profile, flow control information is also transmitted from the source over the bus in at least one flow control time slot (20) associated with the data time slot.

The bits of each of the plurality of groups are error correction encoded and encoded into symbols. The symbols are mapped to different ports for diversity transmission through a plurality of ports.

Abstract: As disclosed, while a wireless communication device (WCD) is idling on a particular carrier frequency of a base station, the base station may receive a message broadcast by that base station, the message specifying multiple relative sets of priority levels defined for a set of carrier frequencies and correlating each of the multiple relative sets of priority levels with respective different WCD operational characteristics. In particular, the message may specify a first correlation of one relative set of priority levels with one WCD operational characteristic and includes a second correlation of a different relative set of priority levels with a different WCD operational characteristic. The WCD may select one of the relative sets of priority levels responsive to the WCD having a WCD operational characteristic that the message correlates with the selected relative set of priority levels. The WCD may then apply the selected relative set of priority levels.
