Abstract: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8?n) bits, where n=the number of bits in C/T field.

Abstract: A wireless telecommunications network supplies a semi-persistent resource that a wireless station can use for special purposes (such as a retransmission of packets for ARQ purposes or a control signal. The semi-persistent resource can be allocated by the system to other terminals if, e.g., a retransmission is not required. Since a retransmission is generally performed in response to a NACK received from a base station, the NACK may itself serve as a token that permits the wireless station to use the semi-persistent allocation. Thus, the technology includes, e.g., a method for resource allocation on a semi-persistent basis and efficient signaling for the usage of such allocation.

Abstract: In certain embodiments, a macrocell base station (BS), such as an LSAS BS, estimates its backhaul channels with a small-cell BS (e.g., a relay or repeater) by averaging multiple instances of a received pilot signal repeatedly transmitted by the small-cell BS. Since the macrocell and small-cell BSs are stationary, averaging the received pilot signal transmissions over time results in the zero-temporal-mean time-dependent component of each backhaul channel as well as zero-temporal-mean noise and interference signals from other wireless nodes to substantially cancel out, enabling the macrocell BS to relatively infrequently estimate a relatively time-invariant, dominant component for each backhaul channel. The macrocell BS uses the estimated dominant components to generate user-data-based downlink transmissions to the small-cell BS. In this way, the processing to estimate channel state information (CSI) data for the backhaul channels is greatly reduced compared to conventional techniques.
