    摘要： Procedures for point association as well as measurement and feedback required to enable point association for CoMP deployment scenario 4 are proposed. In a first novel aspect, a serving eNB configures a first higher-layer configuration for RSRP measurement to be used by a UE for serving point selection. The higher-layer configuration contains multiple CSI-RS configurations, and each CSI-RS configuration indicates a set of resource elements (REs) or subcarriers in both frequency domain and time domain as one CSI-RS resource with non-zero transmission power. The UE then performs RSRP measurements based on the multiple CSI-RS configurations and reports RSRP measurement results to the serving eNB. In a second novel aspect, the serving eNB configures a second higher-layer configuration for CSI reporting based on the reported RSRP measurement results. In a third novel aspect, the serving eNB sends CSI-RS information to the UE for uplink power control.

    摘要： In OFDMA wireless communications systems, pilot pattern design is optimized based on predefined resource block size. The number of pilots and the spacing between pilots within a resource block is determined based on a set of system requirements. In one novel aspect, if resource block size is smaller than three in either frequency or time domain, then the pilots are allocated such that average pilot-to-data distance is minimized and that pilot-to-pilot distance is as large as possible. In one example, m pilots are allocated in an i×j resource block. The resource block is partitioned into n equal sub blocks, where m is a multiple of n. Within each sub block, m/n pilots are positioned such that average pilot-to-data distance is minimized. On the other hand, if resource block size is larger than or equal to three in both frequency and time domain, then pilots are allocated to avoid channel extrapolation.

    摘要： In OFDMA wireless communications systems, pilot pattern design is optimized based on predefined resource block size. The number of pilots and the spacing between pilots within a resource block is determined based on a set of system requirements. In one novel aspect, in a high-rank MIMO system, pilots are allocated within a resource block to avoid channel extrapolation in frequency domain only. Because high-rank MIMO only supports low-mobility environment, time-domain extrapolation is no longer a dominant factor. For uplink transmission, one or more frequency tones at one or more edges of the resource block are reserved to be pilot-free to reduce multiuser synchronization error effect. When continuous resource blocks are jointly used for channel estimation, the upper and lower edges of each resource block are left with blanks such that edge pilots of adjacent resource blocks are not too close to each other to improve channel estimation.

    摘要： A contention-based multi-antenna access request transmission/receiving procedure in MIMO OFDM/OFDMA systems is provided to reduce access latency. A mobile station encodes and transmits an access request over a shared access channel using multiple transmitting antennas, while a base station receives and decodes a number of access requests using multiple receiving antennas. Each access request comprises an access indictor and an access message. In a first MIMO scheme, the mobile station transmits the access indicator as preambles, while the access message is encoded by SFBC/STBC to obtain spatial diversity. At the receive side, the access indicator is exploited as pilots for channel estimation. The access message is decoded using SFBC/STBC decoding algorithm. In a second MIMO scheme, the mobile station performs precoding/beamforming for each of the transmitting antenna to obtain beamforming gain, while the base station performs virtual beam matching based on the detection results of the access indicators.

    摘要： In wireless OFDMA systems, sounding channels are allocated within predefined resource blocks. In a distributed sounding channel allocation scheme, a sounding channel is allocated to meet various design considerations. First, sounding signals do not collide with original pilots transmitted in the same resource block by other mobile stations to achieve good quality channel estimation. Second, sounding pattern does not affect data transmission behavior of other mobile stations in the same resource block. Third, sounding pattern consistency among multiple tiles within each resource block is maintained so that mobile stations do not need to implement additional data mapping rules. In a symbol-based sounding channel allocation scheme, a sounding channel is allocated in the first or the last OFDM symbol of a resource block, while the remaining consecutive OFDM symbols are used for data transmission. The symbol-based sound channel naturally satisfies all design considerations.

    摘要： A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

    摘要： A method of multi-set RRC signaling for ap-SRS configuration is provided to enhance ap-SRS flexibility. An eNB transmits a plurality of sets of UE-specific SRS parameters to a UE via upper layer messaging in a multi-carrier wireless communication system. The eNB also determines triggering information of a selected set of UE-specific SRS parameters and an indicated carrier for the UE. The eNB then transmits an uplink or downlink grant over a primary carrier, the grant comprises triggering information for the UE to send an ap-SRS over the indicated carrier using the selected set of UE-specific SRS parameters. In one embodiment of joint signaling, the plurality of sets of UE-specific SRS parameters are signaled together in a single RRC transmission. In another embodiment of separate signaling, each set of UE-specific SRS parameters is signaled independently.
