    摘要: In one example of the teachings herein, a network base station (16, 18) includes one or more communication interfaces configured to send messages to a wireless communication device, and one or more processing circuits (36) operatively associated with the communication interface(s). The processing circuits (36) are configured to send a reconfiguration message to the device using an existing downlink control channel configuration for the device, which message indicates a new downlink control channel configuration for the device, and, during a window of control channel configuration ambiguity that arises for the device as a consequence of sending the reconfiguration message, send a control message to the device using both the existing and the new downlink control channel configurations. Such a method of operation advantageously avoids the delays that arise if new downlink control signaling towards the device (20) is deferred until receiving confirmation that the device (20) received the reconfiguration message.

    摘要: In one aspect, the teachings herein provide a system and method for reusing the PUCCH format 3 to address the new HARQ-ACK feedback cases encountered in Rel-11, where different UL/DL configurations are involved in the CA configuration of a UE, such as Rel-11 interband TDD CA with different UL/DL configurations on different bands. The various embodiments illustrated by way of example in this disclosure enable reliable and efficient HARQ-ACK feedback for Rel-11 TDD CA without a substantial increase in specification and implementation complexity.

    摘要: Techniques provide additional Hybrid-ARQ indication resources for LTE TDD subframes that are normally without conventional LTE PHICH resources or that have too few LTE PHICH resources. In some embodiments, a modified PHICH is created using unused REGs in the control region of the downlink subframe. In others, a modified PHICH resides within the resources of an AL=1 PDCCH, and is formed using encoding and modulation processes that differ from normal PDCCH processing. In other embodiments, the PUSCH HARQ feedback bits are carried by a conventional LTE PDCCH, which is distinguished from other PDCCHs by scrambling it with a new type of RNTI: HARQ indicator Radio-network temporary identifier (HI-RNTI). In still other embodiments, the modulation symbols of PHICH are then placed on top of those normally reserved for PDCCHs. For such overlapped radio resources, the modulation symbols from the modified PHICH will replace those from normal PDCCHs for transmission.

    摘要: Collision mitigation for scheduling requests, SRs, on the physical uplink control channel, PUCCH, in Long Term Evolution, LTE, radiocommunication systems is described. Various types of SR collision mitigation information can be transmitted from a base station eNodeB (32) to a user equipment, UE(36). The UE can use the collision mitigation information to determine how to transmit its SRs. The network or base station (32) can use its knowledge of the SR collision mitigation information sent to various UEs (36) (and/or additional information) to resolve SR collisions on the uplink.
