Methods and apparatuses of UE for an efficient neighbor cell search in a wireless communication network. A method of a UE comprises: receiving system information including time instance information for performing measurements on neighboring cells; identifying a time instance included in the time instance information; determining, based on a comparison between a current absolute time and the time instance, whether to perform the measurements on the neighboring cells; and skipping performing the measurements on the neighboring cells based on a determination that the current absolute time is before the time instance.

Among other things, aspects, features, and implementations of wireless mesh networks and wireless mesh network devices are described.

Methods, apparatus, and systems for wireless communications are described. Example methods, devices, and systems are described that utilize a precoding matrix indicator (PMI) computed based at least in part on first signals received via a first cell and on second signals received via a second cell. Information in a measurement information message may be used as part of computing a PMI. The measurement information message may indicate resources of a first cell and a second cell for use in computing the PMI. A wireless device may receive first signals via the first cell and second signals via the second cell based on information in the measurement information message, and may use these signals to compute the PMI. The computed PMI may be used in communications with a base station. For example, the wireless device may receive a packet beamformed employing the computed PMI.

Systems, apparatuses, and methods are described for wireless communications. A base station may send, to a wireless device, one or more configuration parameters of a primary cell and a secondary cell. The one or more configuration parameters may comprise: a first preamble for a first beam failure recovery (BFR) procedure of the primary cell, and a second preamble for a second BFR procedure of the secondary cell. The wireless device may send the first preamble via a time-frequency resource associated with the primary cell to perform the first BFR procedure. The wireless device may send the second preamble via a time-frequency resource associated with the primary cell to perform the second BFR.

The first circuitry may be operable to establish a first UE Receive (Rx) beam as being for reception of data from a first eNB. The second circuitry may be operable to process a transmission including Downlink Control Information (DCI), wherein the DCI carries an eNB cell-switching indicator. The first circuitry may also be operable to establish a second UE Rx beam as being for reception of data from a second eNB based on the eNB cell-switching indicator.

The present disclosure relates to an electronic device, a communication method and a storage medium in a wireless communication system. There is provided an electronic device on user side, comprising a processing circuitry configured to: based on cell pre-configuration information, measure beams transmitted by a serving cell and at least one non-serving cell; in response to a predefined measurement-based event, send a beam report including at least L1 measurements and identification information for one or more beams of one or more non-serving cells to the serving cell via L1 or L2 signaling; determine an activated beam of the one or more beams; and set a non-serving cell associated with the activated beam as a serving cell.

Methods and apparatus are provided for enhanced mechanism for RRM measurement in the mmW system. In one novel aspect, the filtered-consolidation measurement result is generated for each cell. The UE measures multiple control beams in an mmW system. The UE either performs a layer-3 filtering on each of the measured control beams or on consolidation measurement results for each control beam of the cell. The UE generates the filtered-consolidation measurement results for each corresponding cell. In another novel aspect, an intra-cell threshold and an inter-cell threshold are configured, wherein the intra-cell threshold is greater than the inter-cell threshold. The UE obtains a consolidation measurement for the serving cell and compares the result with the two preconfigured thresholds. The UE performs different level of control beam measurements based on the comparison of the consolidation measurement of the serving and the two thresholds.

A method of selecting a set of beams to be monitored by a User Equipment, UE, in a telecommunication network, said telecommunication network comprising a Base Station, BS, function coupled to at least one Access Node, AN, serving said UE, said method comprising the steps of receiving measurement data comprising measurements of qualities of beams observed by said UE, wherein said beams originate from said at least one AN to said UE, and originate from at least another AN in said telecommunication network to said UE, retrieving at least one measurement data from a particular UE that matches the received measurement data, wherein the historical database comprises historical measurement data comprising measurements of qualities of beams observed by UE's in said telecommunication network over time, selecting a set of beams to be monitored by said UE based on said retrieved at least one measurement data from said particular UE and based on subsequent measurement data of said particular UE over time in said historical database, and transmitting said selected set of beams to be monitored to said UE.
