Abstract: Solutions pertaining to enhanced support for transmit-receive (Tx-Rx) gap in non-terrestrial network (NTN) communications are proposed. An apparatus implemented in a UE receives from a non-terrestrial (NT) network node of a network an uplink (UL) grant or a configuration that schedules an UL transmission (Tx). The apparatus performs the UL transmission to the NT network node within a transmit-receive (Tx-Rx) transition gap during which no downlink (DL) Tx from the NT network node is expected. The Tx-Rx transition gap includes an UL Tx duration, a pre-UL Tx gap (Gap_start) before a starting time of the UL Tx duration (t_start), and a post-UL Tx gap (Gap_end) after an ending time of the UL Tx duration (t_end). A starting timing of the Tx-Rx transition gap can be expressed as: t_start?timing advance (TA)?Gap_start. An ending time of the Tx-Rx transition gap can be expressed as: t_end?TA+Gap_end.

Abstract: Various solutions for processing timeline enhancement with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine whether a latency requirement of a service is less than a threshold value. The apparatus may use a first processing time capability to perform a transmission in an event that the latency requirement of the service is not less than the threshold value. The apparatus may use a second processing time capability to perform the transmission in an event that the latency requirement of the service is less than the threshold value. The apparatus may apply a scheduling restriction/optimization to perform the transmission when using the second processing time capability.

Abstract: Methods and apparatuses pertaining to device-driven power scaling in advanced wireless modem architectures are described. A processor of a communication apparatus with time-varying peak processing capability during active operations negotiates with a wireless network, to which the communication apparatus is communicatively connected, to select one of a plurality of temporary capability states ranging between zero and peak performance of the communication apparatus. The processor initiates a capability state change such that the communication apparatus enters the selected temporary capability state from a current temporary capability state of the plurality of temporary capability states. The lifetime of the selected temporary capability state exceeds a control information period used by the wireless network to dynamically schedule data transmissions with the communication apparatus.

Abstract: A wireless communication device includes a wireless transceiver to wirelessly receive and transmit radio frequency (RF) signals and sample a signal representative of the received RF signal over a predetermined time period. The receiver stores the sampled signal in a memory. After the predetermined time period, a processor, coupled to the wireless transceiver and the memory, concurrently searches the sampled signal for multiple communication signals each operating according to a corresponding one of multiple, different mobile communication standards. If one of the communication signals is found, the WCD attempts to connect wirelessly with a communication network from which the found communication signal originates.

The transceiver is configured to transmit or receive the subsequent MCI during the subsequent MCI Tx/Rx window as determined based on the first selection model.

A user equipment device in a first wireless coverage area of a wireless network using a time division duplex transmission scheme to designate a maximum timing advance value for uplink transmissions based on potential interference between uplink transmissions made by the user equipment device in the first wireless coverage area or at least one other user equipment device in the first wireless coverage area, and downlink transmissions intended for at least one user equipment device in a second wireless coverage area of the wireless network. The maximum timing advance value may be based on relative cell radii or other cell properties of the first and second wireless coverage areas. A base station may determine the maximum timing advance and transmit the maximum timing advance to the user equipment device.

Abstract: The current invention provides simplifications to the user equipment (UE) radio front end module for the cellular handset or dongle through modification of the existing 3GPP specifications for LTE and WCDMA/HSPA+ in order to support half duplex (HD) operation.

Abstract: Techniques are provided for decoding tail-biting convolutional codes by using information within the received data stream that traditionally has not been used or been available to the convolutional decoder, e.g., cyclic redundancy check (CRC) and bit information known by both the transmitter and receiver. Further, a single parallel trace-back is used that reduces implementation complexity. In addition, the least reliable decisions made during forward processing may be reversed in order to generate additional possible codeword candidates. These techniques can be used to reduce false detection rates (FDRs) and/or detection error rates (DERs).
