    • A computer process, called VGRAM, improves the performance of these string search algorithms in computers by using a carefully chosen dictionary of variable-length grams based on their frequencies in the string collection. A dynamic programming algorithm for computing a tight lower bound on the number of common grams shared by two similar strings in order to improve query performance is disclosed. A method for automatically computing a dictionary of high-quality grams for a workload of queries. Improvement on query performance is achieved by these techniques by a cost-based quantitative approach to deciding good grams for approximate string queries. An approach for answering approximate queries efficiently based on discarding gram lists, and another is based on combining correlated lists. An indexing structure is reduced to a given amount of space, while retaining efficient query processing by using algorithms in a computer based on discarding gram lists and combining correlated lists.

    • A multiple antenna mode control method based on an Access Point comprises the following steps: step 1, the Access Point periodically sends out a multiple antenna mode set or subset supported by the Access Point (S101); step 2, the Station reports a multiple antenna mode set or subset supported by the Station or, reports a multiple antenna mode set or subset supported by both the Station and the Access Point to the Access Point (S105); step 3, a multiple antenna mode is chosen from a multiple antenna mode set or subset supported by both the Station and the Access Point for communicating (S110). As a result, the Station and the Access Point can communicate in a reliable or high-speed antenna mode supported by both sending and receiving sides, and thereby the error frame rate is reduced, and the network throughput is increased.
    • 基于接入点的多天线模式控制方法包括以下步骤:步骤1,接入点周期性地发出由接入点支持的多天线模式集或子集(S101); 步骤2,站报告由站支持的多天线模式集或子集,或者报告站和接入点支持的多天线模式集或子集到接入点(S105); 步骤3,从由站和用于通信的接入点支持的多天线模式集合或子集中选择多天线模式(S110)。 结果,站和接入点可以以发送方和接收方支持的可靠或高速天线方式进行通信,从而降低了错误帧速率,并提高了网络吞吐量。

    • Disclosed is a method the includes determining if a collision will occur between a transmission from a first user equipment that uses a persistently assigned uplink resource (such as for VoIP packet transmissions) and a retransmission from a second user equipment that uses a synchronous non-adaptive automatic repeat request procedure (e.g., synchronous, non-adaptive HARQ). If it is determined that a collision will occur, the method dynamically allocates the first user equipment to another uplink resource to avoid the collision, while if it is determined that the collision will not occur, the first user equipment is not dynamically allocated another uplink resource so that the first user equipment sends its transmission using the persistently assigned uplink resource. The embodiments of this invention pertain to both the base station (e.g., an evolved Node-B) and the user equipment.
