摘要:
In one aspect, a wireless device receives a first data transmission from a base station during a predetermined subframe interval and within a duration that is less than a maximum data transmission duration that is possible within the predetermined subframe interval, and determines a transmission time for transmitting HARQ feedback to the base station such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used for the first data transmission. The wireless device transmits HARQ feedback for the first data transmission at the determined transmission time. In another aspect, a base station transmits the first data transmission and determines a reception time for receiving HARQ feedback such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used. The base station receives HARQ feedback for the first data transmission at the determined transmission time.

Aspects described herein generally relate to communicating between a user equipment (UE) and a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell. An indicator can be transmitted from the cell and received by the UE to implement time division duplexing (TDD) on the uplink frequency band. Based at least in part on the indicator, communicating between the UE and the cell can include separating the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell.

A method is provided for handling resources for uplink semi-persistent scheduling transmission, wherein the resources are reserved periodically for a specific service, the method comprising monitoring data transmitted on the semi-persistent scheduling reserved resources and dynamic scheduled resource, checking whether a specific data element related to the specific service has not been received consecutively for a predefined period on the semi-persistent scheduling reserved resources and dynamic scheduled resource, and determining, when the specific data element has not been received for the predefined period, that the use of the specific service has ended. When it is determined that the use of the specific service has ended, an explicit release for the semi-persistent scheduling reserved resources may be triggered.

A method for transmitting uplink control information and an apparatus therefor are disclosed. In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

Described herein are methods, systems, and apparatus for communicating control information over a primary component carrier (PCell). In one example, a method for wireless communication is described that includes communicating using an enhanced component carrier (eCC) on at least a secondary component carrier (SCell) in a carrier aggregation (CA) configuration. The method may also include using a PCell for control information pertaining to communications on the eCC. The control information may be channel state information (CSI) or acknowledgment/negative-acknowledgment (ACK/NACK) feedback information.

摘要:
A method used in a BS for scheduling a UE, and an associated BS is disclosed. The method includes: allocating one or more DL Resource Blocks (RBs) for transmitting DownLink (DL) data to the UE (S910); determining an UpLink (UL) control channel position for the UE transmitting a Hybrid Automatic Repeat Request (HARQ) feedback of the DL data, based on the allocated one or more DL RBs (S920); and transmitting the DL data to the UE by using the allocated one or more DL RBs (S930). Said method also relates to a method used in a UE for transmitting a HARQ feedback, and an associated UE.
摘要:
The present disclosure describes embodiments of apparatuses, systems, and methods for cross sub-frame by enhanced physical downlink control channel (EPDCCH) transmissions for scheduling of physical downlink share channel (PDSCH) transmissions one or more subframes after the EPDCCH transmission. Cross subframe scheduling may be useful for machine type communication (MTC) user equipment (UE) with reduced bandwidth support including half duplex type MTC UE operating at 1.4 MHz bandwidth.
