摘要： A method for wireless communication is provided, at a half-duplex node operating in TDD mode and may be used with an eNB in an LTE system. The method comprises receiving a configuration of a first set of subframes for a first link communication containing at least one downlink subframe and at least one uplink subframe. A second set of subframes for a second link communication is then determined. This second set includes at least one backward compatible downlink hybrid automatic repeat request process and at least one backward compatible uplink hybrid automatic repeat request process utilizing a second set of subframes. Communication begins with a first set of nodes using the first link and the first set of subframes. A second set of nodes using the second link and the second set of subframes is also used for communication. Communication to a legacy node is also supported.

摘要： Signaling design for interlaced frequency divisional multiplex (IFDM) demodulation reference signals (DMRS) is discussed in which a dynamic indication is provided to a user equipment (UE) from a serving base station that allows the UE to configure transmission of DMRS according to either a single carrier frequency divisional multiplex (SC-FDM) or IFDM configurations, as indicated by the dynamic indication. The IFDM configuration may be applicable to either regular uplink subframes or within the uplink portion of special subframes. In some aspects, power boosting may be provided for the DMRS in order to equalize transmit power between decimated DMRS transmitted with the data tones. Additional aspects may also provide for different offsets to be used depending on the type of uplink control signal transmitted.

摘要： Certain aspects of the present disclosure provide techniques for uplink sounding reference signal (SRS) transmission with precoding. A method for wireless communication by a user equipment (UE) includes receiving a SRS configuration that configures one or more SRS resource sets, each resource set including one or more SRS resources, each SRS resource comprising one or more SRS ports. The UE receives a set of precoders via an indicator, the set of precoders including a precoder associated with each SRS resource and determines one or more precoders to apply for one or more SRS transmissions via one or more of the SRS resources.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of channel state processes scheduled to be performed. The UE may receive a channel state feedback request corresponding to another set of channel state processes. The combination of the set of channel state processes and the other set of channel state processes may be greater than an amount that the UE may process at a given time. The UE may determine a priority for the channel state processes either on an individual or group basis. The UE may determine channel state process (es) to drop based on the determined priorities, and may perform the remaining channel state processes. The UE may generate and transmit a channel state feedback report message based on the performed channel state processes.

摘要： Methods, systems, and devices for wireless communications are described. One or more multiple access-capable user equipments (UEs) may be grouped together for transmitting uplink multiple access communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. The UE may receive configuration information based at least in part on the group to which the UE has been assigned. When assigned to a group, the UEs may also receive a group-specific scrambling code for the uplink multiple access communications, a group-specific power control for the uplink multiple access communications, time and frequency resources to be used for the uplink multiple access communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by multiple access resource units.

摘要： Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.
