    摘要: Embodiments of the invention provide systems and methods for improving user equipment performance in up-link transmission by implementing antenna selection based on channel measurements in the down-link. In various embodiments, first and second antennas are used to receive signals on a downlink and to transmit signals on an uplink. A plurality of signals received on the downlink are used to generate a plurality of antenna parameter measurements derived from multiple correlations of a known reference sequence of data signals transmitted on the downlink. The plurality of antenna parameter measurements is then used to select either the first antenna or the second antenna or a combination of both through splitting of the signal for transmitting data signals by said user equipment device on the uplink.

    摘要: A device, serving cell and method of switching between modes of operation for the device in a cellular network comprises receiving a service via a connection with the serving cell. A condition indicative of deterioration in network service and an absence of a suitable neighbor cell are detected. In response, discovery of relay nodes is initiated. When a suitable relay node is discovered, a mechanism to switch to receiving the service via the suitable relay node is initiated. The service may be a mission critical push-to-talk over Long Term Evolution service. The relay node may be user equipment acting as a user equipment-to-network relay node. When the device is in an RCC_CONNECTED state, the mechanism to switch includes sending a relay mode preference indication to the serving cell, receiving a connection release message from the serving cell, releasing the serving cell connection, and establishing a sidelink connection with the relay.

    摘要: An indication is sent from a mobile station to a network regarding the capability of the mobile station to receive or transmit on two or more carriers simultaneously. The network determines an ideal multi-carrier multi-slot capability of the mobile station from an existing capability indication for single carrier transmission mode of the mobile station; and the mobile station sends in an additional field an indication in respect of a reduction in number of time slots from the ideal multi-carrier multi-slot capability determined by the network.
