摘要： Providing a coding scheme for wireless communication downlink reference signals is described herein. By way of example, a dedicated reference signal is mapped to resources of a wireless channel as a function of an identifier (ID) of a cell in which the reference signal is transmitted. The function can be similar to mapping functions employed for common reference signals, or can be distinct from such functions. As one example of the latter, a dedicated reference signal mapping function can be shifted in time or frequency with respect to the common reference signal mapping function. By employing a mapping function based on cell ID, noise caused by concurrent transmission of reference signals can be mitigated in a manner readily determined by terminals in a wireless network.

摘要： Systems and methodologies are described that facilitate indicating a type of waveform utilized for uplink transmission in a wireless communication environment. An access terminal can select a type of waveform from a set of possible waveform types. Moreover, a reference signal can be generated based upon the selected type of waveform. For instance, a sequence employed to yield the reference signal can be generated and/or chosen as a function of the selected type of waveform. According to another illustration, a tone location and/or a symbol location of the reference signal can be based upon the selected type of waveform. Further, the reference signal can be sent as part of the uplink transmission to the base station from the access terminal. The base station can detect the selected type of waveform utilized by the access terminal for the uplink transmission based upon parameter(s) recognized from the reference signal.

摘要： Methods and apparatuses are provided that facilitate generating sequences for transmitting reference signals (RS) based at least in part on a cell identifier or other parameters common for a plurality of cells. Where the plurality of cells provide similar joint uplink resources to a device in multi-user multiple-input multiple-output (MIMO), the device can transmit a signal to the plurality of cells over the joint uplink resources. For RSs transmitted according to a sequence generated based on a cell specific identifier or other parameters, the device can utilize a cell identifier, or other parameters, common to the plurality of cells such that the plurality of cells can all decode the RSs. In this regard as well, the plurality of cells can each receive or generate the common cell identifier or other parameters to properly decode the RSs.

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： Techniques for generating reference signals in a wireless communication system are described. A set of Q reference signal sequences may be generated based on G pseudo-random sequences and L scrambling sequences, where Q=G·L, G>1 and L>1. The Q reference signal sequences may be used for Q cell identities (IDs), one reference signal sequence for each cell ID. In one design, a Node B may determine first and second indices based on a cell ID of a cell. The Node B may generate a pseudo-random sequence based on the first index, generate a scrambling sequence based on the second index, and generate a reference signal sequence based on the pseudo-random sequence and the scrambling sequence. The Node B may then generate a reference signal for the cell based on the reference signal sequence, e.g., by generating an OFDM symbol with the reference signal sequence mapped to a set of subcarriers.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

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.
