Abstract:
Certain aspects of the present disclosure relate to physical downlink shared channel (PDSCH) transmission schemes with compact downlink control information (DCI) format in new carrier type (NCT) in long term evolution (LTE).
Abstract:
Methods, systems, and devices for wireless communication are described. A receiving device may detect a signal associated with low latency transmissions and decode a non-low latency communication accordingly. The receiving device may receive an indicator from a transmitting device that indicates where and when low latency communications occur. The indication may specify frequency resources or symbols used by the low latency communication. The indicator may be transmitted during the same subframe as the low latency communication, at the end of a subframe, or during a subsequent subframe. The receiving device may use the indicator to mitigate low latency interference, generate channel estimates, and reliably decode the non-low latency communication. In some cases, the interfering low latency communication may occur within the serving cell of the receiving device; or the interfering low latency communication may occur in a neighboring cell.
Abstract:
UE-aided channel selection within unlicensed frequency bands. A base station may communicate with UEs using LTE/LTE-A carrier waveforms (e.g., configured as a secondary cell) in the unlicensed frequency band. The base station may configure UEs for wide-band interference feedback for channels in the unlicensed frequency band. The measurements of wide-band signal strength may be performed by the UEs on channels for which the base station is not currently transmitting, or during silent periods of a configured secondary cell. The UEs may feedback an average total received power over a measurement bandwidth for one or more frequency channels of the unlicensed frequency band. The base station may receive the wide-band signal strength feedback from the UEs and identify potential frequency channels for channel selection for the secondary cell based on its own measurements of the candidate channels, and the wide-band signal strength feedback from the UEs.
Abstract:
Methods and apparatus for providing wireless communications using subframe partitioning are disclosed. Two or more base stations may be allocated subframes in a radio frame. All or part of the subframe allocation may be provided to the associated user equipment (UEs), which may use it to determine signal metrics during assigned subframes for an associated base station.
Abstract:
Methods and apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.
Abstract:
Multiple full channel quality indication (CQI) reports indicative of received signal quality for multiple carriers in wireless communication are transmitted in multiple time intervals of a CQI channel.
Abstract:
Semi-connected state operation for UEs in multiple-access networks is described. In the semi-connected state, UEs may monitor system information and paging, and mobility may be UE-controlled. Base stations may determine whether to transition UEs from the connected state to the semi-connected state based on capabilities, priority, data connections, or loading conditions. Base stations may maintain context information and logical traffic connections for UEs while UEs continue to be served by the base station in the semi-connected state. Thus, when a transition from the semi-connected state to the connected state occurs, the base station does not have to re-establish security parameters, nor re-establish logical traffic connections within the network for carrying control plane and user plane data for the UE. Context information for semi-connected state UEs may be shared between neighboring base stations or base stations within a context area. The techniques may be applied to LTE/LTE-A networks.
Abstract:
Updated media access control (MAC) operations for semi-persistent scheduling (SPS) and discontinuous reception (DRX) operations with enhanced component carrier (eCC) secondary cells (SCells) is disclosed. For SPS operations, an SPS operation is defined and monitored on the eCC SCell which is separate and independent from SPS operations on the primary cell (PCell). The eCC SCell SPS operation may be identified using either the network identifier for the PCell or a newly defined network identifier specifically for the eCC SCell SPS operation. For DRX operations, the DRX operations for the eCC SCell are defined with separate and independent timers from the DRX operations of the PCell.
Abstract:
Techniques are described for wireless communication. A method for wireless communication may include identifying interference at a first node operating in a shared radio frequency spectrum band. The interference may be caused by a second node operating in the shared radio frequency spectrum band. The second node may operate asynchronously to the first node in the shared radio frequency spectrum band. The method may also include adaptively enabling, based at least in part on the identified interference, a synchronization of the first node with at least a third node in the shared radio frequency spectrum band.
Abstract:
Techniques are described for wireless communication. One method includes determining a set of uplink (UL) component carriers (CCs) to use for a user equipment (UE). The set of UL CCs may include at least one UL CC in a first radio frequency spectrum band and at least one UL CC in a second radio frequency spectrum band. The method further includes identifying, for a subframe, uplink control information (UCI) due for transmission, the UCI associated with one or more CCs, and limiting available UL CCs for transmission of the UCI to the at least one UL CC in the first radio frequency spectrum band.
