In particular, these operations need not be performed in the order of presentation. 
     The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment; however, it may. The terms “comprising,” “having,” and “including” are synonymous, unless the context dictates otherwise. The phrase “A/B” means “A or B”. The phrase “A and/or B” means “(A), (B), or (A and B)”. The phrase “at least one of A, B and C” means “(A), (B), (C), (A and B), (A and C), (B and C) or (A, B and C)”. The phrase “(A) B” means “(B) or (A B)”, that is, A is optional. 
     Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a wide variety of alternate and/or equivalent implementations may be substituted for the specific embodiments shown and described, without departing from the scope of the embodiments of the present disclosure. This application is intended to cover any adaptations or variations of the embodiments discussed herein. Therefore, it is manifestly intended that the embodiments of the present disclosure be limited only by the claims and the equivalents thereof. 
     As used herein, the term “module” may refer to, be part of, or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality. 
       FIG. 1  schematically illustrates a wireless system  100  comprising an evolved Node B (eNB)  101  and a user equipment (UE)  201  for BRS-RP report and others, in accordance with various embodiments. In some embodiments, eNB  101  may comprise a control module  102 , a transceiver  103 , a plurality of antennas  104 , and others. Control module  102  may generate a plurality of beam reference signals (BRSs) which may be used to measure channel state and quality for each of transmission beams  105  generated by antennas  104 . Control module  102  may further map the BRSs onto transmission beams  105  before transceiver  103  transmit the BRSs via the transmission beams to UE  201 . In some embodiments, transceiver  103  may further receive, from UE  201 , a BRS-RP report to report power of receiving at least one of the BRSs on at least one of the transmission beams by at least one directional antenna panel of UE  201 . 
     In some embodiments, besides the receiving power, the BRS-RP report may comprise a BRS identifier to identify the BRS associated with the receiving power, a transmission beam identifier to identify the transmission beam that the BRS may be mapped on, a receiving antenna panel identifier to identify a directional antenna panel of UE  201  that may receive the BRS on the transmission beam, and/or others. In a case that UE  201  comprises more than one directional antenna panels, the receiving power in the BRS-RP report may be the highest receiving power for each of the at least one of the BRSs on each of the at least one of the transmission beams across the directional antenna panels. In some embodiments, the receiving power in the BRS-RP report may be higher than a threshold. In some embodiments, the number for the reported transmission beams associated with the BRS-RP may be pre-determined. In some embodiments, the number of the reported receiving antenna panel associated with the BRS-RP may be predetermined. In some embodiments, the receiving antenna panel identifier may comprise 1 bit flag to identify whether the receiving antenna panel is a default panel or not. In some embodiments, the directional antenna panel of UE  201  may comprise an antenna array of multiple antenna elements, which may point to a spatial direction based on at least one polarization direction through beamforming. In view of this, the receiving antenna panel identifier may be alternatively used to identify the antenna port(s) that receive the BRS on the transmission beams. 
     With the above-stated scheme of BRS-RP reporting, the overhead for UE  201  to transmit the BRS-RP report may be reduced. More details for the BRS-RP report may be described in the below with reference to  FIGS. 2-4 . 
     In some embodiment, control module  102  of eNB  101  may select transmission beam candidates from the BRS-RP report. For example, control module  102  may select N transmission beam candidates having highest receiving power from the BRS-RP report. Control module  102  may then use the transmission beam candidates to configure channel control information, such as a channel state information-reference signal (CSI-RS), an enhanced physical download control channel (EPDCCH), and/or others. For example, control module  102  may include the receiving antenna panel identifier associated with the transmission beam candidates in the CSI-RS configuration information, the EPDCCH configuration information, and/or others. 
     For another example, control module  102  may determine whether one or more transmission antenna panels (or transmission antenna ports) should be used for the transmissions between eNB  101  and UE  201 , at least in part based on whether the receiving antenna panel identifier associated with the transmission beam candidates identifies one or more receiving antenna panels. More specifically, if the receiving antennal panel identifier identifiers that the transmission beam candidates are associated with one receiving antenna panel, control module  102  may determine to use single transmission antenna panel (or related transmission antenna ports) for the transmission between eNB  101  and UE  201 . If the receiving antennal panel identifier identifiers that the transmission beam candidates are associated with more than one receiving antenna panel, for example, to a default antenna panel as well as an alternative antenna panel, control module  102  may determine to use dual or more transmission antenna panels (or related transmission antenna ports) for the transmission between eNB  101  and UE  201 . This way may help eNB  101  to more efficiently navigate transmission resource to serve the UE(s). In some embodiments, eNB  101  may select a transmission beam with a highest BRS-RP value for further communication between eNB  101  and UE  201 . 
     In some embodiments, UE  201  may comprise a transceiver  202 , a control module  203 , a plurality of antennas  204 , and/or others. Transceiver  202  may receive the plurality of BRSs mapped on the plurality of transmission beams  105  via receiving beams  205  generated by antennas  204 . In some embodiments, the receiving beam may comprise an optimized receiving beam of each receiving antenna panel which may be obtained from a previous beam acquisition process. The receiving antenna panel may comprise the directional antenna panel having an antenna array of multiple antenna elements, which may point to a spatial direction based on at least one polarization direction through beamforming. 
     Control module  203  may calculate the power of receiving each BRS mapped on each transmission beam  105  by each of the receiving antenna panel(s). In some embodiments, UE  201  may comprise one or more receiving antenna panels, for example, a default antenna panel and an alternative antenna panel. Control module  203  may then generate the BRS-RP report comprising the receiving power, a BRS identifier to identify the BRS associated with the receiving power, a transmission beam identifier to identify the transmission beam that the BRS may be mapped on, a receiving antenna panel identifier to identify the directional antenna panel or a receiving antenna port identifier to identify a receiving antenna port associated with the directional antenna panel that may receive the BRS on the transmission beam, and/or others. In some embodiments, if UE  201  comprises more than one directional antenna panels, the receiving power in the BRS-RP report may be the highest receiving power for each of the at least one of the BRSs on each of the at least one of the transmission beams across the directional antenna panels. In some embodiments, the receiving power in the BRS-RP report may be higher than a threshold. In some embodiments, the number for the reported transmission beams associated with the BRS-RP may be pre-determined. In some embodiments, the number of the reported receiving antenna panel associated with the BRS-RP may be predetermined. In some embodiments, the receiving antenna panel identifier (or the receiving antenna port identifier) may comprise 1 bit flag to identify whether the receiving antenna panel (or the receiving antenna port) is a default panel (or a default antenna port) or not. 
     With the above-stated scheme of BRS-RP reporting, the overhead for UE  201  to transmit the BRS-RP report may be reduced. More details for the BRS-RP report may be described in the below with reference to  FIGS. 2-4 . 
     It should be understood that other embodiments may implement other technologies for the wireless system  100  of  FIG. 1 . In some embodiments, besides the 5 th  generation wireless technology, the wireless system  100  may use a variety of other wireless access technologies such as Code Division Multiple Access (CDMA). Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA). Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and/or others in compliance with an Institute of Electrical and Electronics Engineers (IEEE) 802 system, a 3rd Generation Project Partnership (3GPP) system, a 3GPP Long Term Evolution (LTE) system, and/or a 3GPP2 system. 
     In some embodiments, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . 
       FIG. 2  schematically illustrates an example of BRS-RP measurement by the UE having directional antenna panel(s), in accordance with various embodiments. As illustrated in  FIG. 2 , the BRS-RP measurement result by the directional antenna panel(s) of UE  201  may include BRS-RP measurement values as well as indications of the directional antenna panel(s), transmission beams and/or others that may be associated with the BRS-RP measurement. For example, the receiving power of the BRS mapped on the transmission beam #N Tx−1  may be measured as x 0;N     Tx−1    dBm by the directional antenna panel # 0  of UE  201 , wherein N Tx−1  may represent the number of transmission beams  105  carrying the BRSs whose receiving power may be measured. 
     It should be understood that other embodiments may implement other technologies for BRS receiving information measurement by UE  201 . For example, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . For another example, UE  201  may comprise one directional antenna panel and the panel index as shown in  FIG. 2  may be omitted. For yet another embodiment, the panel index may be replaced by receiving antenna port index, such as ports (A, B) to replace panel # 0 , ports (C, D) to replace panel # 1 , and so on. 
       FIG. 3  schematically illustrates an example of a BRS-RP report for a directional antenna panel of UE  201 , in accordance with various embodiments. As illustrated in  FIG. 3 , besides the measured BRS-RP, the BRS-RP report may comprise an antenna panel identifier, a BRS identifier and a transmission beam identify to identify the receiving antenna panel, the BRS and the transmission beam associated with the measured BRS-RP. In some embodiments, the BRS-RP report may further comprise a cell identifier to identify a serving cell from which the identified transmission beam may be served. 
     In some embodiments, the BRS-RP report as illustrated in  FIG. 3  may comprise a predetermined highest BRS-RP values, rather than all measured BRS-RP values in order to save the BRS-RP report overhead. In some embodiments, the BRS-RP report may comprise the BRS-RP values which are higher than a threshold. For example, if UE  201  comprises two or more receiving antenna panels, the BRS-RP report for a secondary or other subsequent antenna panel may comprise a BRS-RP value meeting the following condition:
 
γ′−γ j &lt;Δ
 
wherein, γ′ may represent the maximum BRS-RP value measured by the previous receiving antenna panel, such as the antenna panel # 0 , γ j  may represent a BRS-RP value measured by a subsequent receiving antenna panel, such as the antenna panel # 1 , Δ may represent a difference threshold.
 
     In some embodiments, eNB  101  may request UE  201  to report the BRS-RP values measured by a specific receiving antenna panel. ENB  101  may know the number of directional antennal panel(s) that UE  201  may have and their capacities through the UE capability reporting, when UE  201  accesses the wireless system  100 . The specific receiving antenna panel may be obtained through a previous BRS-RP report process. 
     It should be understood that other embodiments may implement other technologies for BRS-RP report of  FIG. 3 . For example, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . For another example, UE  201  may comprise one directional antenna panel and the panel index as shown in  FIG. 3  may be omitted. For yet another embodiment, the panel index may be replaced by receiving antenna port index, such as ports (A, B) to replace panel # 0 , ports (C, D) to replace panel # 1 , and so on. 
       FIG. 4  schematically illustrates an example of a BRS-RP report for all directional antenna panel(s) of the UE, in accordance with various embodiments. As illustrated by  FIG. 4 , the BRS-RP report may comprise a highest BRS-RP value measure by all receiving antenna panel(s) of UE  201  for a BRS on a transmission beam. For example, if UE  201  comprises two or more directional antenna panels, the BRS-RP value in the BRS-RP report as illustrated in  FIG. 4  may represent the highest BRS-RP value measured across all of the directional antenna panels for a specific transmission beam. In this way, UE  201  may not need to report the BRS-RP values measured by each of the directional antenna panels. 
     The BRS-RP report may further comprise an antenna identifier to identify the directional antenna panel which measures the highest BRS-RP. In some embodiments, the antenna identifier may comprise 1 bit flag to identify whether the directional antenna panel is a default panel or not. In a case that the BRS-RP report may report antenna port(s) rather than the antenna panel(s), the antenna identifier may identify whether the antenna port(s) which may receive the BRS on the transmission beam with the highest receiving power is a default antenna port(s) or not. 
     It should be understood that other embodiments may implement other technologies for BRS-RP report of  FIG. 4 . For example, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . 
       FIG. 5  schematically illustrates a method of reporting the BRS-RP from the UE to the eNB, in accordance with various embodiments. As illustrated in  FIG. 5 , in some embodiments, transceiver  202  or other devices of UE  201  may receive BRSs mapped on transmission beams  105  from eNB  101 , through one or more directional antenna panels of UE  201  in block  501 . In some embodiments, the optimized receiving beam from each directional antenna panel which may be obtained via a previous beam acquisition process may receive the BRSs. The directional antenna panel may comprise an antenna array having multiple antenna elements, which may point to a spatial direction based on at least one polarization direction through beamforming. 
     In block  502 , control module  203  or other devices of UE  201  may measure BRS-RP values for receiving the at least one BRS on the at least one transmission beam. Examples of the BRS-RP measurement may be illustrated in  FIG. 2 , which may comprise BRS-RP values and identifiers of the directional antenna panel(s), BRSs, transmission beams and others that may be associated with the BRS-RP values. 
     In block  503 , control module  203  or other devices of UE  201  may generate the BRS-RP report to report the BRS-RP value(s) for the at least one BRS on the at least one transmission beam. Examples of the BRS-RP report may be illustrated in  FIGS. 3 and 4 , which may include BRS-RP values for each directional antenna panel or for all directional antenna panel(s) through, for example, reporting the highest BRS-RP values for the at least one BRS on the at least one transmission beam across all of the directional antenna panel(s). For other example, the BRS-RP report may comprise the BRS-RP values which are higher than a threshold. For other example, the number for the reported transmission beams associated with the BRS-RP may be pre-determined. For other example, the number of the reported receiving antenna panel associated with the BRS-RP may be predetermined. For other example, the receiving antenna panel identifier (or the receiving antenna port identifier) may comprise 1 bit flag to identify whether the directional antenna panel is a default panel or not. In block  504 , transceiver  202  or other devices of UE  201  may transmit the BRS-RP report to the eNB. 
     It should be understood that other embodiments may implement other technologies for BRS receiving information measurement by UE  201 . For example, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . For another example, UE  201  may comprise one directional antenna panel and the panel index as shown in  FIG. 2  may be omitted. For yet another embodiment, the panel index may be replaced by receiving antenna port index, such as ports (A, B) to replace panel # 0 , ports (C, D) to replace panel # 1 , and so on. 
       FIG. 6  schematically illustrates a method of utilizing the BRS-RP for channel control from the eNB to the UE, in accordance with various embodiments. As illustrated in  FIG. 6 , in some embodiments, transceiver  103  or other devices of eNB  101  may transmit the BRSs via transmission beams  105  to UE  201 , in block  601 . In block  602 , transceiver  103  or other devices of eNB  101  may receive the BRS-RP report from UE  201 , wherein the BRS-RP report may report the receiving power associated with the as least one BRS on the at least one transmission beam which may be measured by the directional antenna panel(s) of UE  201 . 
     Examples of the BRS-RP report may be illustrated in  FIGS. 3 and 4 , which may include BRS-RP values for each directional antenna panel or for all directional antenna panel(s) through, for example, reporting the highest BRS-RP values for the at least one BRS on the at least one transmission beam across all of the directional antenna panel(s). For other example, the BRS-RP report may comprise the BRS-RP values which are higher than a threshold. For other example, the number for the reported transmission beams associated with the BRS-RP may be pre-determined. For other example, the number of the reported receiving antenna panel associated with the BRS-RP may be predetermined. For other example, the antenna identifier associated with the BRS-RP may comprise 1 bit flag to identify whether the directional antenna panel of UE  201  is a default panel or not. 
     In block  603 , control module  102  or other devices of eNB  101  may select the select transmission beam candidates at least in part based on the BRS-RP report. For example, control module  102  or other devices of eNB  101  may select N transmission beam candidates having highest receiving power from the BRS-RP report. In block  603 , control module  102  may then utilize the selected transmission beams and/or other information associated with the selected transmission beams to configure channel control information, such as a channel state information-reference signal (CSI-RS), an enhanced physical download control channel (EPDCCH), and/or others. For example, control module  102  may select include the receiving antenna panel identifier associated with the transmission beam candidates in the CSI-RS configuration information, the EPDCCH configuration information, and/or others. For other example, control module  102  may determine whether one or more transmission antenna panels should be used for the transmissions between eNB  101  and UE  201 , at least in part based on whether the receiving antenna panel identifier associated with the transmission beam candidates identifies one or more receiving antenna panels. More specifically, if the receiving antennal panel identifier identifiers that the transmission beam candidates are associated with one receiving antenna panel, control module  102  or other devices of eNB  101  may determine to use single transmission antenna panel (or related transmission antenna ports) for the transmission between eNB  101  and UE  201 . If the receiving antennal panel identifier identifiers that the transmission beam candidates are associated with more than one receiving antenna panel, for example, to a default antenna panel as well as an alternative antenna panel, control module  102  or other devices of eNB  101  may determine to use dual or more transmission antenna panels for the transmission between eNB  101  and UE  201 . This way may help eNB  101  to more efficiently navigate transmission resource to serve the UE(s). 
     It should be understood that other embodiments may implement other technologies for BRS receiving information measurement by UE  201 . For example, the BRS-RP report may be replaced by a BRS receiving quality (BRS-RQ) report which may report BRS receiving quality, or other reports which may report BRS receiving information and help eNB  101  to configure transmission channels between eNB  101  and UE  201 . For another example, UE  201  may comprise one directional antenna panel and the panel index as shown in  FIG. 2  may be omitted. For yet another embodiment, the panel index may be replaced by receiving antenna port index, such as ports (A, B) to replace panel # 0 , ports (C, D) to replace panel # 1 , and so on.

If the UE  800  is in an RRC_Connected state, where it is still connected to the eNB as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device may power down for brief intervals of time and thus save power. 
     If there is no data traffic activity for an extended period of time, then the UE  800  may transition off to an RRC_Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE  800  goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The device cannot receive data in this state, in order to receive data, it must transition back to RRC_Connected state. 
     An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
