摘要:
Certain aspects of the present disclosure provide techniques that may help resolve ambiguities between a base station and a user equipment (UE) regarding the use or resource elements (REs) reserved for special purposes, such as PDSCH muting and/or CSI-RS.
摘要:
A method of wireless communication comprises receiving a plurality of codewords and transmitting a downlink feedback message by spatially bundling acknowledgments for the received plurality of codewords. In some designs, an accompanying grant message is transmitted with the downlink feedback message.
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:
Certain aspects of the present disclosure propose methods for supporting uplink transmit diversity in a wireless communication system. The proposed methods may eliminate ambiguity in decoding physical downlink control channel aggregation level and resources that are used by different antennas of a user equipment. In addition, a method is proposed for resource allocation for ACK/NACK repetition.
摘要:
A laser glass fiber with a core of the fiber composition, comprising a silicate glass host, one or more glass network modifiers, one or more glass network intermediators, and Thulium ions, Holmium ions, or a combination of Thulium ions and Holmium ions. The fiber emits laser light from 1.7 micron to 2.2 micron.
摘要:
Providing for secondary synchronization encoding utilizing a primary synchronization channel (P-SCH)-related scrambling code is described herein. Scrambled secondary synchronization codes (SSCs) can be assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSCs. Selection can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.
摘要:
Maintaining uplink hybrid automatic repeat request (HARQ) compatibility with extended radio frames includes partitioning subframe groups over an extended radio frame having a length of time greater than a time defined for a single radio frame. User equipment (UE) suspends PUSCH (physical uplink shared channel) retransmission in the extended radio frame, in accordance with hybrid automatic repeat request (HARQ) timing of a subframe group assigned to the UE.
摘要:
According to certain aspects, techniques for periodically reporting channel state information (CSI) on protected and unprotected resources are provided. The protected resources may include resources in which transmissions in a first cell are protected by restricting transmissions in a second cell.
摘要:
An enhanced random access procedure for current and future versions of user equipment communicating with base stations. A random access preamble is transmitted, wherein the random access preamble comprises release version information of a user equipment. A payload portion of a random access response is derived, and a contention resolution message is received.
摘要:
Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.
