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: An enhanced acknowledgement indicator channel is discussed that multiplexes acknowledgement signals for multiple uplink signals from various user equipments (UEs) into the enhanced acknowledgement indicator channel. The channel is divided into a number of paired data and pilot resource element groups that can be precoded independently of one another, such that each paired resource element group is precoded using a different or independent precoding than the other paired resource element groups. If the base station determines a failure to decode any uplink signals, instead of sending acknowledgement signals over the indicator channel, the base station may, instead, generate uplink grants for retransmission of the uplink signals.

Abstract: Methods, systems, and devices are described for bundling data transmissions in a wireless communication network. Bundled data transmissions may depend on subframe types and may account for multicast service single frequency network (MBMS) subframes. Bundled data transmissions may be repeated and a density of reference signals in the bundled data may be increased. The density of reference signals may be increased according to various techniques, including inserting additional pilot tones in the subframe, inserting additional pilot tones only in the bundled data, or adding additional pilot tones in one or more types of subframes. Multiple subframes used to transmit the bundled data may include, for example, a MBSFN subframe and a non-MBSFN subframe, and increasing density of reference signals may be performed differently for MBSFN subframes and non-MBSFN subframes. In some examples, bundled data transmissions are restricted to subframes of one type.

Abstract: Methods, systems, and devices are described for uplink power control in a wireless communications network. Power settings for various uplink transmissions may account for, or be based on, prior uplink channel repetition levels. Uplink power settings may also be based on other factors, including a power ramp-up associated with prior uplink transmissions. Certain uplink power settings may be computed by a user equipment (UE) or they may be indicated to a UE from another system node. The described features may be implemented as coverage enhancement techniques, for example, for machine-type communication (MTC).

Abstract: The subject technology provides for performing clear channel assessment (CCA) in LTE-U. Transmissions may be monitored in a resource reserved for CCA. An energy of the transmissions is detected over a shorter duration than an assigned slot in the resource reserved for CCA. A beacon may be transmitted in a slot assigned to a wireless entity for CCA in response to detecting a clear channel based on the monitoring. In another aspect, a beacon transmission for CCA and a timing for the monitoring are adapted in response to detecting the transmissions for a consecutive number of CCA periods. Further, the subject technology provides for adjusting to a maximum power for transmission of a beacon in a slot assigned to a mobile station for CCA in response to detecting a clear channel based on the monitoring.

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.
