    摘要: A method for adaptively disabling receiver diversity is provided. The method can include a wireless communication device determining an active data traffic pattern; defining a threshold channel quality metric based at least in part on a threshold channel quality needed to support a threshold quality of service for the active data traffic pattern; comparing a measured channel quality to the threshold channel quality metric; and disabling receiver diversity in an instance in which the measured channel quality metric satisfies the threshold channel quality metric.

    摘要: Mobile devices, base stations, and/or relay stations may implement a method for an improved and reliable automatic repeat request feedback indication. A mobile device (UE) may establish communication within a wireless network, and indicate to the network that the UE is a special type device, e.g. a constrained device. The network (base station) may then not send an indication on a physical indicator channel to the UE when certain conditions are met, and instead, the mobile device may interpret control information received from the network on a physical control channel as a negative acknowledgment indication corresponding to an automatic repeat request from the network. The UE may then perform a retransmission according to the interpreted control information. A new control information format may be used to further define how the network and UE implement the automatic repeat request process, to reduce the total number of bits required in the control information.

    摘要: Method and apparatuses for providing special radio provisions to link budget limited devices. A network node receives from a link budget limited cellular communication device, prior to initiation of a cellular connection between the link budget limited cellular communication device and a base station of the cellular network, requested values of one or more cellular settings for the cellular connection. The network node determines approved values for the one or more cellular settings in response to receiving the requested values of the one or more cellular settings from the link budget limited cellular communication device. The network node communicates the approved values for the one or more cellular settings to the link budget limited cellular communication device, prior to initiation of the cellular connection. The network node communicates the approved values for the one or more cellular settings to the base station of the cellular network, prior to initiation of the cellular connection.

    摘要: Enhanced random access procedures for link-budget-limited user equipment (UE) devices are disclosed. A user equipment device may transmit a first message containing a Physical Random Access Channel (PRACH). The PRACH contains instances of a Zadoff-Chu sequence, and may be transmitted repeatedly as part of a single random attempt, to facilitate correlation data combining at the base station. The available Zadoff-Chu sequences may be partitioned among a plurality of sets, each set being associated with a respective Doppler shift range (or frequency hop pattern or time repetition pattern). A UE device may signal Doppler shift (or other information) to the base station by selection of one of the sets. The first PRACH transmission and the following PRACH transmission may occur in consecutive subframes. A UE device may select from a special set of Zadoff-Chu sequences (different from a conventional set of sequences), to signal its status as a link-budget-limited device.
