The invention discloses a method (600) for use in a wireless communications system (100) in which there is at least one node (110-115) which controls the traffic to and from all user terminals (130) in a cell (120) within the system. In the system (100), use is made of the TDD principle for communication between said controlling node (110-115) and its user terminals (130), and according to the method (600), the controlling node transmits (610) a beacon signal for use as a signal quality indicator by the user terminals, said beacon signal being transmitted in a first TDD time slot (232). The user terminals (130) measure (620) the signal quality of the beacon signal and the signal quality in at least a second TDD time slot (234), and report (630) measurements of the signal qualities in both said first and second time slots to the controlling node.

A cable assembly (100), comprises a housing (10) formed by a base portion (101) having a first top surface (1011) and a mating portion (102) having a second top surface (1021), and the housing has a receiving space therein. A plurality of conductive contacts (311, 331) are retained in the housing. A cable (7) is entered into the receiving space and electrically connected with the conductive contacts. A pulling member (52) is moveable relative to the housing in a horizontal direction, and comprises a cooperating portion (524) at a front end thereof. And a latching member (51) is cooperated with the pulling member and assembled to the housing for latching with a complementary connector. The latching member comprises an engaging section (513) assembled to the housing, a latching section (515) disposed on the top of the base portion and an actuating section (5140) disposed between the engaging section and the latching section. The actuating section is interconnected with the cooperating portion and capable of being actuated by the cooperating portion of the pulling member.

An electrical connector (100) for mating with a mating connector (800) along a mating direction includes an insulative housing (1), a pair of latches (7) and a number of terminals (5) received in the insulative housing. The insulative housing has a front face (11), a pair of side walls (13) each defining an opening (131), a pair of receiving spaces (12, 14) defined between the pair of side walls, and a partition (16) disposed between the pair of receiving spaces. The pair of latches are mounted in the openings and each formed with an engaging portion (75). The latch resiliently yields in the opening along a moving direction perpendicular to the mating direction to permit the engaging portion moveable between a locked position and an unlocked position.
