摘要： A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

摘要： Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

摘要： A method includes receiving a cross-subframe assignment in a first subframe, targeting a second subframe in which a transmission power control (TPC) command is to be applied. The method may also include adjusting transmit power in accordance with the TPC command during a third subframe, a predefined number of subframes after the first subframe. Another method includes receiving a cross-subframe assignment in a first subframe. The cross-subframe assignment targets a second subframe in which a first TPC command is to be applied. The method may also include receiving a nominal grant in the first subframe that targets an identified subframe to which a second TPC command is to be applied. The method may also include adjusting the transmit power according to the first TPC command, the second TPC command or a function of the first TPC command and the second TPC command during the second subframe or the identified subframe.

摘要： Methods, apparatuses, and articles of manufacture are disclosed for adjusting a power level in connection with transmitting parallel uplink channels. In one aspect, a user equipment determines a power-limited condition in which a total transmit power of a group of power-controlled channels exceeds a maximum level in a transmission subframe. The user equipment may determine, in an iterative fashion, power backoff values by which to establish a configured maximum power level. The parallel uplink channels in the group may be prioritized and different backoff values may be used with channels having different priorities. The user equipment may thereafter adjust a transmit power of the power-controlled channels based on the configured maximum power level.

摘要： Systems and methodologies are described that facilitate initializing scrambling sequence generation in a wireless communication environment. Scrambling sequence generation can be initialized (e.g., at a start of each subframe, . . . ) at least in part as a function of a type of Radio Network Temporary Identifier (RNTI). Further, the type of RNTI utilized for initialization of scrambling sequence generation can correspond to a transmission type (e.g., whether the transmission is related to system information, paging, random access response, scheduled transmission or contention resolution message of a random access procedure, SPS traffic, regular unicast traffic, . . . ). Moreover, the scrambling sequence can be leveraged to scramble data for transmission over a data channel (e.g., Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), . . . ). Further, a receiving wireless communication apparatus can utilize a descrambling sequence similarly yielded based upon the type of RNTI corresponding to the transmission type.
