A method and apparatus are provided to provide for timely switching between antenna port configurations as the mode of operation of a mobile terminal changes which may, in turn, dictate different combinations of the MIMO, CoMP and/or CA capabilities. In this regard, a method is provided that includes utilizing one or more antennas in a first antenna port configuration in a first mode of operation. The method may also receive a command that triggers switching to another antenna port configuration and then determines another one of a plurality of antenna port configurations to be utilized in response to the command. The method may then utilize one or more antennas of the another one of the antenna port configurations in a second mode of operation. A corresponding apparatus and computer program product are also provided.

摘要:
Access to a wireless network is attempted by sending on a random access channel RACH at a first transmit power a first preamble comprising a signature sequence that is randomly selected from a set of signature sequences. After the access attempt from sending the first preamble is determined unsuccessful, access to the wireless network is re-attempted by sending on the RACH at a second transmit power a second preamble comprising a signature sequence, in which the second transmit power is no greater than the first transmit power. Embodiments variously combine different options: the signature sequences of the first and second preambles are each randomly selected separately, or the signature sequence of the first preamble is re-used in the second preamble; the first and second transmit powers are each equal to an initial transmit power, or the second transmit power is the initial power and less than the first transmit power.
摘要:
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring/implementing full-duplex communications between UEs and a network on a partial frequency domain in wireless communications, e.g., in LTE systems. This may allow UEs with different transmission capabilities to operate on the same deployment bandwidth and to use time dependence of an operational mode. According to an embodiment, a network element, such as eNB, may configure a deployment bandwidth in a frequency domain for wireless communications between UEs and the network, wherein one or more full-duplex regions of the deployment bandwidth are allocated for full-duplex communications and one or more half-duplex regions of the deployment bandwidth are allocated for half-duplex communications.

摘要:
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring/implementing by a network/network element a partial full-duplex in time dependent operational mode for wireless communications between UEs and the network/network element, e.g., in LTE systems. The time dependent partial full-duplex may further include bandwidth allocations for the full-duplex and half-duplex time intervals. In the half-duplex time periods, undesirable interference and self-interference effects during signal detection by the UEs and/or eNBs may be reduced to an advantage. The network may configure a time dependence of the partial full-duplex operational mode for wireless communications between UEs and the network, wherein during at least one time interval the network configures a full-duplex operational mode and during at least one other time interval the network configures a half-duplex operational mode for the wireless communications between the UEs and the network.
