    摘要: A user equipment (UE) receives a signal comprising multiple resource blocks and configured for receiving a subframe comprising multiple time-frequency resources, the time-frequency resources comprising at least two control channel candidates. The UE determines a first control channel candidate of the at least two control channel candidates in the subframe, determines a first antenna port (AP) associated with the first control channel candidate, decodes the first control channel candidate based on the first AP, determines a second control channel candidate of the at least two control channel candidates in the subframe, determines a second AP associated with the second control channel candidate, and decodes the second control channel candidate based on the second AP, wherein the AP used for decoding the first control channel candidate is distinct from the AP used for decoding the second control channel candidate.

    摘要: A method for selective use of control channel element (CCE)-based implicit pointing. The method includes the step of determining whether a number of multiple user elements (UE) within a multi-user multiple-input multiple-output (MU-MIMO) group is greater than the number of resource blocks allocated to the MU-MIMO group. If the number of UEs in the MU-MIMO group is greater than the number of resource blocks allocated to the MU-MIMO group, the method further includes transmitting to each of the UEs of the MU-MIMO group acknowledgements on acknowledgement channels within a first acknowledgement bank and acknowledgements on acknowledgement channels within a second acknowledgement bank. A first portion of the UEs of the MU-MIMO group receives the acknowledgements on the acknowledgement channels within the first acknowledgement bank and a second portion of the UEs of MU-MIMO group receives the acknowledgements on the acknowledgement channels within the second acknowledgement bank.

    摘要: A communication system provides for adaptive rank determination, for example, a rank 2 transmission in instances where a rank 1 transmission may be indicated under supported feedback modes in current standards where no explicit power adaptation can be assumed, for example, where a user equipment (UE) is limited to reporting a rank 1 channel due to a large dynamic range of a signal or due to a signal received by the UE from one base station (BS) antenna port drowning out a signal received by the UE from another BS antenna port. The communication system provides for the UE to implement rank 2 transmission in such instances by using per-antenna port power control at a BS serving the UE. In one embodiment, the BS controls the rank determination at the UE by signaling transmit power or power offset related parameters to use for rank and transmission parameters determination and feedback.

    摘要: A communication system is provided wherein a user equipment (UE) receives control information from a wireless network. The UE monitors control channel candidates using common reference signals (CRS) and monitors enhanced control channel candidates using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode, such as transmission mode 9, for receiving a downlink shared traffic channel based on DMRS. The UE monitors control channel candidates only using CRS when the UE is configured in a second transmission mode, such as any of transmission modes 1-6, for receiving a downlink shared traffic channel based on CRS. The UE then receives downlink control information (DCI) in a subframe in one of the monitored control channel candidates or enhanced control channel candidates in the subframe.

    摘要: A wireless communication user terminal obtains uplink access configuration information on a physical downlink control channel (PDCCH) addressed to a plurality of user terminals by processing the PDCCH based on a first system information received from a base station on a physical broadcast channel (PBCH) and based on synchronization information. The terminal sends a signature waveform based on the uplink access configuration information, prior to receiving system information in addition to the first system information, whereby the signature waveform enables the base station to transition from a relatively low power operating mode to a relatively high power operating mode.
