摘要： Techniques for delivering data recovered by a HARQ entity in proper order to higher layers in a CDMA system. In a method, packets are received from the HARQ entity by the re-ordering entity and missing packets among the received packets are detected. Packets may be transmitted in a sequential order based on transmission sequence numbers (TSNs) assigned to the packets, and missing packets may be detected based on the TSNs of the received packets. Delivery of received packets later than the missing packets are stalled because higher layers expect data in-order. A determination is thereafter made whether each missing packet is (1) subsequently received from the HARQ entity or (2) lost, by successively eliminating HARQ channels that may be used to send the missing packet. Received packets previously stalled by each missing packet are delivered after the missing packet is determined to be lost or received.
摘要翻译：用于将由HARQ实体恢复的数据以适当的顺序递送到CDMA系统中的较高层的技术。在一种方法中，由重排序实体从HARQ实体接收分组，并且检测出接收分组中的丢失分组。可以基于分配给分组的传输序列号（TSN）以顺序的顺序发送分组，并且可以基于接收的分组的TSN来检测丢失的分组。接收到的数据包的传送迟于丢失的数据包被停止，因为更高的层要求数据按顺序排列。此后，确定每个丢失的分组是否（1）随后从HARQ实体接收或（2）通过连续消除可用于发送丢失分组的HARQ信道而丢失。在丢失的数据包被确定丢失或接收之后，由每个丢失的数据包先前停止的接收到的数据包被传送。

摘要： Noise measurements are made within a fraction of a single symbol period of a longest orthogonal code symbol. A control processor identifies an unoccupied code having a spreading factor that is less than a longest spreading factor for the system. A despreader measures symbol energy based on the unoccupied code and a noise estimator generates noise estimations based on the measured symbol energies. The subscriber station uses similar techniques in order to perform channel estimations within a period that is a fraction of a symbol period of a longest-spreading-factor code.

摘要： Systems and methodologies are described that facilitate defining a new control region over resources allocated for communicating general non-control data in a legacy network specification. The new control region can comprise multiple control channels, which can be multiplexed together and/or with general data channels. Devices can receive control data over the new control region as well as information regarding the region, such as location of the region, location of specific resources, multiplexing schemes, frequency hopping patterns, and/or the like to appropriately decode relevant control data. This allows for expanded control resources to support multicarrier assignments, large numbers of devices being addressed, special operation modes, new downlink control information (DCI) formats, and/or the like.

摘要： Certain aspects of the present disclosure provide methods and apparatus for subframe muting and/or discontinuous reception (DRX) mode related to sleep mode for user equipment (UE) relays. One method generally includes measuring, at a UE functioning as a relay (i.e., a UE relay), signals of one or more other UEs functioning as relays during one or more particular subframes and reporting the measurements of the signals to an apparatus. Another method generally includes determining, at a first UE functioning as a relay, that no UEs are being served by the first UE; based on the determination, increasing an interval between broadcast signals; and transmitting the broadcast signals according to the increased interval.

摘要： Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.

摘要： Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type(s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e.g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.

摘要： Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.
