摘要： A user equipment (UE) indicates hybrid automatic repeat request (HARQ) buffer memory size to a RAN node and reports HARQ buffer loading to the RAN node. For example, the UE can support reporting of HARQ memory size as part of UE capability or as associated with a UE category. In another example, the UE supports HARQ buffer status reports from the UE to the RAN node, regarding the actual loading of the HARQ buffer at the UE. In another example, the HARQ loading report can be triggered by the RAN node or provided by the UE based on an event trigger.

摘要： Systems and methods of scheduling UL and DL D2D transmissions are generally described. The nUE determines whether a subframe is DL or UL, and schedules PRAs based on the amount of URLLC, non-URLLC, new retransmission UL and DL data and the number of UEs associated with each data type. URLLC data is prioritized and allocations within the same data type distributed evenly; consecutive subframes for a UE are of opposite types if URLLC UL and DL data exists for the UE, and multiple UEs associated with the same data type are allocated evenly if a sufficient amount of PRAs exist. If the PRAs are insufficient to serve the UEs, a credit-based mechanism is used whereby UEs with a greater amount of credit are served first. When multiple PRAs are assigned to the same UE, a single HARQ retransmission is scheduled either for each PRA or for all of the PRAs.

摘要： Configuration data is acquired (S21) at a transmitting apparatus, which indicates a number of transmission channels to be used for processing data packets at a receiving apparatus. The number of transmission channels is higher than a number of soft decoding buffers available at the receiving apparatus, the soft decoding buffers being usable for storing data packets to be retransmitted. The configuration data is transmitted (S22) to the receiving apparatus via an air interface. The receiving apparatus receives (S11) the configuration data from the transmitting apparatus and controls (S12) processing of data packets received from the transmitting apparatus based on the configuration data.

摘要： A dual watch subscriber unit (SU) in a wireless communication system transmits short data during an active call in response to a request to transmit short data. The SU transmits, via a transceiver at the SU, pending short data on an inbound data channel of an inbound traffic frequency. One of prior to or after transmitting the short data, the SU substantially simultaneously receives: via a first receiver of the transceiver, missed communication media of the active call missed during transmitting of the pending short data on a first outbound channel of a first outbound traffic frequency; and via a second receiver of the transceiver, second communication media of the active call, transmitted prior to or after the missed communication media of the active call, on a second outbound channel of a second outbound traffic frequency. The SU then plays back media from the missed and second communication media.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine a reference number for component carriers (CCs) for partitioning a soft buffer when the number of the CCs configured for carrier aggregation (CA) operation exceeds a threshold. For example, the reference number of CCs may be associated with the soft buffer size or the category of the UE. The UE may allocate the soft buffer based on a comparison between the reference number of CCs and the number of the CCs. The UE may utilize portions of the soft buffer with different CCs based, for example, on the reference number of CCs and the status of the corresponding hybrid automatic repeat request (HARQ) processes. The UE may store a set of log-likelihood ratios (LLRs) for each HARQ process in the corresponding portions of the soft buffer. In some examples, CCs may be configured into priority groups with weighting factors for soft buffer partitioning.

摘要： The disclosure provides for recovering from radio link desynchronization. A network node may determining a first validity rate of a first plurality of protocol data units (PDUs) including a length indicator transmitted over the radio link using ciphering based on a hyperframe number and determining a second validity rate of a second plurality of PDUs without a length indicator transmitted over the radio link using ciphering based on the hyperframe number. The network node may detect desynchronization of the hyperframe number based on the first validity rate and the second validity rate. The network node may initiate a reset procedure to set a new hyperframe number for the radio link. The network node may detect desynchronization when the first validity rate is less than a first threshold, and the second validity rate is greater than or equal to a second threshold.

摘要： A method of wireless communication includes determining when all HARQ processes are associated with packages for retransmission. The method also includes determining when no new packages are pending in a UE buffer and when a received grant is insufficient for retransmission of any of the HARQ processes. The method further includes determining possible block sizes supported by each allocated time slot identified in the received grant. The method still further includes retransmitting the package of a selected HARQ process with maximum available power.
