Abstract:
Certain aspects of the present disclosure relate to a technique for enabling transmission of sounding reference signals for uplink and downlink scheduling.
Abstract:
In co-channel heterogeneous networks, subframes may be partitioned between several evolved Node Bs (eNBs) including eNBs of different power classes. Lower power eNBs may have a reduced range due to interference from neighboring higher power eNBs. Rate matching on the UE allows the UE, during communication with a low power eNB, to avoid transmitting on Resource Elements (REs) which experience interference from common resource signals of an interfering base station.
Abstract:
Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.
Abstract:
An apparatus and method for communicating information in a relay downlink backhaul between a base station and at least one relay node comprising: determining a first starting symbol index of at least one control channel in the relay downlink backhaul; determining a second starting symbol index of at least one data channel in the relay downlink backhaul; and communicating information using the at least one control channel based on the first starting symbol index and the at least one data channel based on the second starting symbol index in the relay downlink backhaul. In one example, the apparatus and method comprise receiving information using a control channel based on a first starting symbol index and a data channel based on a second starting symbol index in the relay downlink backhaul.
Abstract:
Certain aspects of the present disclosure provide closed loop and open loop power control techniques for each antenna of the user equipment (UE). The access point may measure the received signals from each antenna of the user equipment, calculate a power adjustment parameter for each antenna of the UE, and transmit the parameters to the UE. The UE may use the adjustment parameters to determine the transmit power value for each antenna. In addition, the UE may measure the path loss for each antenna and update the transmit power per antenna based on the path loss and other parameters.
Abstract:
System(s) and method(s) are provided that facilitate a flexible channel quality indicator (CQI) reporting directives or policies. A CQI reporting directive delivers an improved tradeoff between reporting accuracy and overhead by establishing subband-specific reporting periods, reporting repetitions, or power requirements. The CQI reporting directive is based at least in part on channel conditions, traffic requirements, and scheduling techniques. Automated optimization and negotiation of a CQI reporting directive based on communication performance is also incorporated.
Abstract:
Certain aspects of the present disclosure provide techniques for enabling half-duplex (HD) operations between one or more user equipments (UEs) and one or more base stations.
Abstract:
A method of wireless communication provides narrow bandwidth operation within a wider LTE system bandwidth. Wideband information is transmitted to a first set of user equipments (UEs). Also, narrowband information is transmitted to a second set of UEs. The second set of UEs operate in a narrower bandwidth than the first set of UEs.
Abstract:
A method for mitigation of lost resource allocation synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a Hybrid Automatic Repeat Request (HARQ) transmission and/or retransmission process is described. The method includes determining whether resource allocation is out of synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a hybrid automatic repeat request (HARQ) transmission and/or retransmission process. The method further includes mitigating a loss of resource allocation synchronization between the UE and the eNodeB during the HARQ transmission and/or retransmission process.
Abstract:
Techniques are provided for communicating control information for aggregated carriers. For example, a method includes receiving one or more assignments for a plurality of aggregated carriers. For example, the at least one of the plurality of aggregated carriers is a time division duplexing (TDD) carrier having a different subframe configuration than at least another one of the plurality of aggregated carriers. The method may include communicating control information for the plurality of aggregated carriers over one of the plurality of aggregated carriers.
