System and Method for Resource Block-Specific Control Signaling
20180014294 · 2018-01-11 ·

A system and method is disclosed for resource block-specific control signaling in a communication system. Communication data is transmitted using a transmission channel comprising a plurality of resource blocks defined by allocating time-frequency slots in a transmission resource. Resource block control information is transmitted in a “feed-forward” manner to a user end (UE) or group of UEs using channels physically mapped into scheduled resource blocks (RBs) for that user or group of users. Embodiments of the invention provide an RB-specific control channel that comprises RB control elements that are embedded within scheduled resource blocks. The invention, therefore, reduces the amount of control information that must be transmitted by common or shared control channels.

20180013528 · 2018-01-11 ·

The present invention provides a communication method in a base station and a corresponding base station. The method includes: a base station communicating with a user equipment in multiple serving cells, and configuring a search space sharing indicator for the multiple cells. The method further includes: the base station sending a physical downlink control channel (PDCCH)/enhanced physical downlink control channel (EPDCCH) based on a specific search space of the user equipment to the user equipment, where in the case of configuring the user equipment with a carrier indicator field (CIF) or an extended carrier indicator field (ECIF) and configuring the user equipment with a shared search space, a candidate location of a control channel element (CCE) of the PDCCH/enhanced control channel element (ECCE) of the EPDCCH detected by each serving cell configured to share the search space in the whole search space is determined by a cell identification of another configured serving cell sharing the search space therewith. Correspondingly, the present invention further provides a communication method in a user equipment and a corresponding user equipment.

Apparatus and methods for communication with respective communication types

Communications may be effected in a communications environment involving a plurality channels having disparate bandwidth and channel center frequency indexes. Communications are effected using first communications type with a first channel bandwidth and first channel center frequency index. Communications are also effected via a second communications type using a separate set of fields indicating a second channel bandwidth and a second channel center frequency index, the second channel bandwidth being different than the first channel bandwidth and the second channel center frequency index being different than the first channel center frequency index. The channel center frequency index and bandwidth communicated in each communication may utilize separate subfields.

20180013655 · 2018-01-11 ·

Systems and methods that use adaptive control of communication protocol parameters in a network of moving things. Each network device may share information identifying communication protocol parameters used by the network device through periodic broadcasts, which may be received by neighboring network devices that are within communication range. The neighboring network devices may then adjust their own communication protocol parameters accordingly when attempting to communicate with the first network device and their own neighboring network devices. Network devices that have not received the shared information may use information about their geographic location and the geographic location of neighboring network devices to estimate values of some communication protocol parameters that will provide more effective communication.

The present invention relates to a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.

Nested frequency hopping for data transmission

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a discovery reference signal from a base station on an anchor channel. The UE may perform a first random or pseudorandom frequency hopping procedure to identify a plurality of downlink carriers for a first time period. The UE may perform a second random or pseudorandom frequency hopping procedure within the plurality of downlink carriers to select one of the plurality of downlink carriers as the uplink channel for a second time period. The UE may then transmit an uplink communication during the second time period on the selected uplink channel. In some examples, the uplink communication may be transmitted based at least in part on time division multiplexing (TDM) information.

Protocols for multi-access point coordinated multi-user transmissions

Methods, systems, and devices for wireless communications are described. An access point (AP) may transmit, to a second AP and during a first portion of a transmission opportunity (TxOP), a request to participate in a multi-user (MU) transmission. The AP may receive, from the second AP and during the first portion of the TxOP, an indication of intent to participate in the MU transmission during the second portion of the TxOP, the indication of intent including a resource request of the second AP for participation in the MU transmission. The AP may transmit, during an initial period of the second portion of the TxOP, a trigger signal to the second AP indicating a set of one or more resources for the second AP during the MU transmission. The AP may participate, in conjunction with the second AP and during the second portion of the TxOP, in the MU transmission.
