Abstract: An outer encoder (612) and an inner encoder (622, 632) encode subsets of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. The use of a combiner 644 at an outer decoder (648) enables better outer decoding of symbols.

Abstract: Techniques for retransmitting data via RLP in a CDMA (e.g., cdma2000) system with a first retransmission mechanism provided by the RLP and a second retransmission mechanism provided by an HARQ-CF. In one method, missing RLP frames are first detected (e.g., by a receiver RLP). A dynamic timer is then maintained (e.g., by a receiver HARQ-CF) for each RLP frame detected to be missing. The dynamic timers are event-driven and have variable time durations. Each dynamic timer is updated based on events known to the receiver HARQ-CF. Fixed timers with fixed time durations may also be maintained (e.g., by the receiver RLP) for the missing RLP frames. Whether or not a missing RLP frame is lost is determined based on the dynamic timer and the fixed timer (if any) maintained for the RLP frame. A NAK may be issued for retransmission of each RLP frame deemed to be lost.

Abstract: Transmissions on the dedicated channel are encoded using a set of parameters that are picked from a large selection of potential parameters. If the remote station does not know the particular set of parameters that were used by a base station, then the remote station would have to attempt to decode the transmission using every set of parameters, until the transmission is decoded correctly. This is an inefficient methodology. Hence, transmission format information is typically transmitted on a broadcast channel so that a remote station could receive the transmission format information. However, the broadcast channel has reliability problems. New methods and apparatus are presented to allow a base station to determine an overlapping set of Walsh code sequences that can be used to send the transmission format information on the dedicated channel, rather than a broadcast channel. (620) Using the overlapping set allows the remote station to decode the information.

Abstract: Methods and apparatus are presented for dynamically adjusting parameters of an outer-loop algorithm, which is used to determine the feasibility of a transmission format. The parameters of the outer-loop algorithm are adjusted according to channel conditions. In one embodiment, an erasure-based approach is used to determine whether to incrementally increase or incrementally decrease a margin parameter in the outer-loop algorithm. Once one margin parameter is altered, other margin parameters can be adjusted accordingly. (500)

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a listen-before-talk (LBT) procedure to use for transmitting a downlink signal to a user equipment (UE) on a shared radio frequency spectrum band. The LBT procedure may be a group LBT procedure associated with a first set of contention window durations or an individual listen-before talk procedure associated with a second set of contention window durations. The base station may determine a contention window duration corresponding to the identified LBT procedure, perform the identified LBT procedure using the determined contention window duration, and transmit the downlink signal to the UE based on the performed LBT procedure.

Abstract: Autonomous uplink (AUL) for wideband new radio (NR) unlicensed (NR-U) operations is disclosed. For user equipments (UEs) that have been configured for AUL transmissions and have received an activation signal to activate the AUL capabilities, further indications may be used to enable AUL transmissions on AUL transmission opportunities (TxOPs) that overlap the timing of a current TxOP reserved by a serving base station, but that are allocated outside of the resources reserved for the current TxOP. A UE that identifies a desired, next AUL TxOP that overlaps the current base station-initiated TxOP duration, but is allocated for resources outside of the current TxOP resources determines whether it has obtained an enablement indication either directly from the serving base station or implicitly, based on current conditions at the UE. When the UE determines that it has obtained an enabling indication, it may then perform AUL transmissions via the overlapping AUL TxOP.
