Abstract: A method of enabling downlink (DL) flow control in a high speed packet access (HSPA) network is provided. The method includes detecting, by a user equipment (UE) radio link control (RLC) layer, at least one missing packet data unit (PDU) during a radio frequency (RF) outage in a dual subscriber identity module (SIM) dual standby (DSDS) operation, triggering, by the UE RLC layer, a status PDU indicating the at least one missing downlink PDU, transmitting, by the UE RLC layer, the status PDU to the HSPA network, and receiving, by the UE RLC layer, the at least one missing PDU, which is re-transmitted from a HSPA network RLC layer.

Abstract: A method and apparatus are provided to generate a preamble signal. A peak of each pulse of the preamble signal is synchronized with a sensitivity region of a super regenerative receiver (SRR). The method and apparatus are configured to transmit, to the SRR, a data packet comprising the preamble signal, wherein the data packet is a baseband signal corresponding to the preamble signal.

Abstract: A method and apparatus are provided for determining a Transmission Power Control (TPC) command of an UpLink (UL) channel in a User Equipment (UE). The method includes storing TPC commands received through each Radio Link (RL) for preset combining periods, before entry into Discontinuous Transmission (DTX); combining the stored TPC commands; if all of the TPC commands are UP commands, determining a combined TPC command of the UL channel as a power level derived using a TPC command received in a designated previous DownLink (DL) slot among DL slots included in each RL, and controlling a transmit power of the UL channel, in a current DL slot which uplink transmission is resumed, using a power level corresponding to the determined TPC command.

Abstract: Determination of transmission power control commands in a UE by combining TPC commands received during DTX/DRX modes. The combining is done on those TPC commands which are received on different radio links after ignoring TPC commands which might be received in a DL slot overlapping with no UL transmission. The UE thus uses the combined TPC commands as derived at the time of entry into DTX for the second UL DPCCH preamble transmission which leads to increase in link reliability and subsequent conservation of power by the UE. The UE uses the same power as derived in the previous slot for resumption of transmission when all the TPC commands, received in the DL slot overlapping with no UL transmission, are UP. TPC commands for the transmission of the 2nd DPCCH preamble at transmission resumption is determined by combining stored TPC commands from each of the radio links that were received by the UE while entering into DTX gap and said TPC commands could not be applied with the newly received TPC commands.

Abstract: A method of efficient state transition between CELL_DCH and CELL_FACH states is provided. According to the method, the transmission of configuration data through a physical data channel is reduced by using pre-configuration information or previously received/stored information for state transition. The indication regarding the use of pre-configuration information or previously received/stored information for state transition is conveyed through a high speed shared control channel (HS-SCCH), thus reducing the information sent through a high speed physical data shared channel (HS_PDSCH).
