摘要： At least one sPDCCH monitoring set including sPDCCH DL control candidates to be monitored by a device in a sTTI of the subframe can be indicated to the device, where an sTTI can be shorter in length than a subframe length TTI. An sPDCCH belonging to one of the at least one sPDCCH monitoring set can be transmitted to the device. The sPDCCH can schedule DL data packet transmissions in a sPDSCH. The sPDCCH can also indicate a rate-matching indicator that indicates at least one OFDM symbol. A sPDSCH can be transmitted rate-matched at least around a set of frequency resources belonging to the at least one OFDM symbol indicated by the rate-matching indicator.

摘要： Apparatuses, methods, and systems are disclosed for scheduling of transmission time intervals. One apparatus includes a processor that determines a first semi-persistent scheduling resource assignment indicating a first set of resources including a first multiple time domain resources. Each time domain resource of the first multiple time domain resources has a first transmission time interval length. The processor also determines a second semi-persistent scheduling resource assignment indicating a second set of resources including a second multiple time domain resources. Each time domain resource of the second multiple time domain resources has a second transmission time interval length, and the first transmission time interval length is different from the second transmission time interval length. The apparatus includes a transmitter that transmits the first semi-persistent scheduling resource assignment using a first semi-persistent scheduling radio network identifier, and transmits the second semi-persistent scheduling resource assignment using a second semi-persistent scheduling radio network identifier.

摘要： A method and apparatus for discontinuous reception for a shortened transmission time interval and processing time includes a device monitoring for data transmission scheduling assignments during an active time of a DRX cycle, and detecting a transmission during the active time. The method further includes the device starting a first timer, in response to the detecting, wherein the first timer is set for a first timer value that specifies an amount of time between detecting the transmission and starting a second timer that extends the active time by a second timer value. The first timer value is determined based on one or both of a selected first TTI length from multiple TTI lengths for which the device can be enabled and/or a selected shorter first processing time over a second processing time associated with a TTI length used by the device.

摘要： For determining reference signal locations, a method determines a number of Transmission Time Intervals (TTI) in a scheduled transmission of a plurality of TTI. The method further determines one or more reference signal locations based on the number of TTI and one or more of a parameter received from a higher layer wherein the higher layer is higher than a physical layer, a subframe index, a subband size, and a Time Division Duplex (TDD) configuration for the scheduled transmission.

摘要： A method and apparatus can provide for signaling of a higher layer message. A higher layer message from a base station for monitoring control channel candidates in at least one shortened transmission time interval in a subframe and set of resource blocks corresponding to control channel candidates in the at least one shortened transmission time interval can be received. The higher layer can be higher than a physical layer. The shortened transmission time interval can be shorter than a subframe-length transmission time interval. Whether at least one resource block of the set of resource blocks at least partially overlaps with a broadcast control channel or signal can be determined. Control resource elements used for transmission of a control channel candidate based on the determination whether the at least one resource block of the set of resource blocks at least partially overlaps can be determined.

摘要： A channel state information request requesting a device to feedback channel state information can be received. Whether the channel state information request corresponds to regular latency based operation or reduced latency based operation can be determined. Channel state information can be derived based on a first reference resource when the channel state information request corresponds to regular latency based operation. Channel state information can be derived based on a second reference resource when the channel state information request corresponds to reduced latency based operation. The reduced latency based operation can have a latency less than the regular latency based operation. The derived channel state information can be reported to a network.

摘要： A resource allocation assignment for a set of scheduled TTIs can be received from a network in a first TTI belonging to the set of scheduled TTIs. A first set of resources for receiving a first portion and a second set of resources for receiving a second portion of a first downlink user data in the first TTI can be determined based on the resource allocation assignment. The first downlink user data corresponding to at least a first transport block in the first and the second set of resources can be received. A third set of resources for receiving a first portion and a fourth set of resources for receiving a second portion of a second downlink user data in a second TTI belonging to the set of scheduled TTIs can be determined based on the resource allocation assignment. The second downlink user data corresponding to at least a second transport block in the third and the fourth set of resources can be received.
