    摘要: Techniques, apparatuses, and systems for using identification sequences in a wireless communication system can include receiving information indicative of a pilot code detected by a wireless device, the pilot code being shared by multiple Femto Access Points (FAPs) that each provide wireless service in at least a portion of the coverage area; receiving information indicative of an identification sequence detected by the wireless device that is associated with the pilot code, using the information indicative of the identification sequence to identify one of the FAPs that share the pilot code; and performing a hand-off of the call to the identified FAP to continue to provide wireless service for the call via the identified FAP.

    摘要: A method for dynamic adjustment of downlink/uplink resource allocation ratio in a long-term evolution (LTE) time division duplex (TDD) system is disclosed. The method includes replacing at least one of an uplink subframe and a downlink subframe with a mute subframe in a subframe pattern, indicating a first downlink/uplink resource allocation ratio. Thereafter, the mute subframe is replaced with either the uplink subframe or the downlink subframe to form another subframe pattern. The subframe pattern including the mute subframe is obtained from a lookup table, such that the replacing the mute subframe results in the other pattern. A data transmission in accordance with the other subframe pattern, indicating a second downlink/uplink resource allocation ratio, may be scheduled. Hybrid Automatic Repeat-request (HARQ) processing may be implemented after the at least one of the uplink subframe and the downlink subframe is replaced with the mute subframe in the first subframe pattern.

    摘要: A retransmission method for a time division duplexing self-adaptive frame structure, and a network side device relate to a technology of dynamically allocating uplink and downlink sub-frames in an LTE-advance (3GPP Release11) TDD communication system. The method comprises: during transmission of a TDD self-adaptive frame, for an uplink sub-frame, if a frame structure, of which an RTT period of PHICH and PUSCH of the uplink sub-frame is 10 ms, corresponding to the uplink sub frame is found in 7 types of defined frame structures, then sending PHICH data on a corresponding downlink sub-frame in the found frame structure, and sending retransmission data on the corresponding uplink sub-frame in the found frame structure. The solution ensures HARQ compatibility of an uplink data channel of R10UE. In addition, A/N feedback of the PDSCH is configured according to the uplink A/N resolution, thereby improving retransmission performance.
