Abstract: Systems and methods for managing the transmission of multiple signals on one or more uplink (UL) channels using carrier aggregation in LTE-A systems. A UE simultaneously transmits signals such as ACK/NACK and periodic CSI using one or more uplink channels, such as a physical uplink shared channel (PUSCH) and/or a physical uplink control channel (PUCCH), by increasing the resources used to transmit at least one of those signals. According to one aspect, a UE simultaneously transmits ACK/NACK signals and periodic CSI signals by multiplexing those signals on the PUSCH. Certain aspects avoid frequently dropped periodic CSI signals and provide mechanisms to ensure that ACK/NACK signals are transmitted.

Abstract: Techniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent scheduling, a scheduling message may be used to send a semi-persistent assignment for multiple transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry an ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message carrying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.

Abstract: Methods, systems, and devices for multi-carrier scheduling in wireless communications networks. The described techniques may be employed to minimize hybrid automatic repeat requests (HARQ) delay in a wireless communications network utilizing one or more TDD component carriers and one or more FDD component carriers. Scheduling of TDD uplink (UL) and downlink (DL) may be determined based on an FDD component carrier. A number of HARQ processes may be determined for a TDD component carrier based on DL/UL configuration of the TDD component carrier. Scheduling may include overwriting certain HARQ transfers. The described techniques may apply to any TDD DL/UL configuration.

Abstract: Techniques for supporting multimedia broadcast/multicast services (MBMS) are described. In an aspect, resources used for MBMS services may be provided with a multi-tier structure. In the first tier, resources (e.g., subframes) used for a multicast control channel (MCCH) for MBMS services may be signaled in a system information block (SIB). In the second tier, resources (e.g., subframes) for channels carrying data for MBMS services may be signaled via the MCCH. In one design, a base station/cell may determine resources used to send a MCCH. The cell may generate a SIB comprising information indicative of the resources used to send the MCCH. The cell may send the SIB in a broadcast control channel (BCCH). The cell may send the MCCH on the resources indicated by the information sent in the SIB. The cell may send other channels carrying data for MBMS services based on information sent in the MCCH.

Abstract: An enhanced physical downlink control channel (e-PDCCH) may provide carrier aggregation (CA) enhancements, help support new carriers which may not be backwards compatible, reduce control channel capacity limitations of coordinated multipoint (CoMP) transmissions, and enhance DL MIMO. In wireless communication networks, such as Long Term Evolution (LTE), user equipments (UEs) may monitor both a common search space and a UE-specific search space in a control region. A search space may comprise a set of channel control element (CCE) locations where a UE may find its PDCCHs. One or more CCEs are used to transmit each PDCCH. Certain aspects provide methods and apparatus for determining a search space comprising a subset of CCEs located on a band edge of available frequency resources, and performing a search of the search space to decode at least one PDCCH.

Abstract: A method for wireless communication between at a base station and a user equipment is provided that accommodates multiple data streams of varying traffic characteristics. The base station may configure semi-persistent scheduling (SPS) occasions having a particular periodicity. Each SPS occasion having multiple slots associated with multiple physical downlink shared channels (PDSCH). A message is transmitted to a user equipment (UE) indicating the SPS occasions. Subsequently, the base station transmits data to the UE over the multiple PDSCH during the indicated SPS occasions. The base station can dynamically adjust the number of PDSCH for an SPS occasion, wherein different number of PDSCH are used in two sequential SPS occasions. Also, the PDSCH in a same SPS occasion may use at least one of: different encoding schemes or different modulation schemes.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit sets of network coding encoded packets user equipments (UEs), and each set of network coding encoded packets may be associated with a redundancy overhead. The base station may dynamically identify the redundancy overhead for transmitting sets of network coding encoded packets to each UE based on a failure rate associated with a previous transmission of network coding encoded packets to that UE. For example, the base station may determine a failure rate associated with a transmission of a first set of network coding encoded packets and may identify a redundancy overhead associated with one or more second sets of network coding encoded packets based on the determined failure rate. In some cases, the base station may identify different redundancy overheads for transmissions of network coding encoded packets to different UEs.

Abstract: Methods, systems, and devices for identification reinterpretation in sidelink control information (SCI) are described. A first user equipment (UE) may transmit to a second UE or device, on a sidelink channel, SCI. The SCI may include a partial source and destination identifier fields and may indicate to the second UE to apply a first interpretation of multiple different interpretations for the partial source identifier field and the partial destination identifier field. For example, the SCI may indicate to interpret the partial source identifier field and the partial destination identifier field in combination as a source identifier field, as a destination identifier field, or as a partial source identifier and a partial destination identifier. The UE may transmit a medium access control (MAC) packet including a MAC header with identifier fields set to be complementary to the SCI.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a sidelink resource configuration indicating physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) occasions on which to monitor a PSCCH for a grant from a second UE. The first UE may determine an active time for monitoring the PSCCH based on a discontinuous reception (DRX) mode for a link with the base station, the DRX mode including an active state in which a physical downlink control channel (PDCCH) is monitored and an inactive state in which the PDCCH is not monitored. The first UE may monitor the PSCCH during one or more of the PSCCH/PSSCH occasions that coincide with the active time.
