Further, UE1 and UE2 can also communicate with each other via a communication channel therebetween, which can be any wireless channel or other medium known in the art suitable for the transmission of data as described herein.

Those skilled in the art will appreciate that the various illustrative blocks, modules, circuits, and processing logic described in connection with the implementations disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality, without reference to a specific

[0016] Processor modules 113, 123, 133 can be implemented or embodied with general- purpose processors, content addressable memory, digital signal processors, application specific integrated circuits, field programmable gate arrays, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein.

The memory modules 114, 124, 134 can also each include non-volatile storage for storing instructions to be executed by the processor modules 113, 123, 133, respectively.

[0018] According to some implementations of the present disclosure, two user equipments (UE1 and UE2) can be paired to enable UE aggregated transmission. UE1 can receive an uplink (UL) transmission grant in resources corresponding to the physical downlink control channel (PDCCH) configuration information of UE1. UE1 can inform UE2 to transmit UE1’s data, including uplink control information (UCI), to a base station BS. In this embodiment, UE1 or UE2 does not need to report the pairing information to the BS. The BS also does not know that UE1 and UE2 are paired for UE aggregated transmission.

[0019] In this embodiment, it can be assumed that UE1 and UE2 are paired for UL aggregated transmission. UE2 is configured to transmit data from UE1 to the BS, and the data interaction between UE1 and UE2 is timely.

[0020] Aggregated transmission with minimal system modification

[0021] According to some implementations of the present disclosure, another method of wireless communication is disclosed, which includes receiving, by a base station BS, data of a first user equipment UE transmitted by a second UE according to a transmission configuration.

[0022] Dynamic scheduling of PUSCH by UL grant

[0023] According to some embodiments, UE1 can receive a UL grant from UE2, and the UL grant schedules a Physical Uplink Shared Channel (PUSCH) for transmitting data of UE1. UE1 can transmit the data to be transmitted to UE2 according to the UL grant. UE1 can also transmit the time-frequency resource information configured for the PUSCH in the UL grant to UE2. Optionally, UE1 can also transmit the UL grant to UE2. UE2 can then transmit the data to be transmitted from UE1 according to the UL grant information. The UL grant, such as a Downlink Control Information (DCI), is typically used to schedule a PUSCH, and can be transmitted in a Physical Downlink Control Channel (PDCCH) in the resources corresponding to the PDCCH configuration information.

[0024] Alternatively or additionally, UE1 can only transmit the information necessary for the PUSCH transmission in the UL grant. For example, the information that can be transmitted from UE1 to UE2 includes resource information, beam information, number of layers information, and power control related information. The resource information includes at least one of the following: Physical Resource Block (PRB) information, symbol information, slot information, and carrier information carrying the PUSCH. According to some embodiments, the carrier used by UE1 to transmit data to UE2 can be the same or different from the carrier used by UE2 to transmit the PUSCH.

[0025] UE2 can then receive the data and the UL grant from UE1. UE2 can thus transmit the data (from UE1) based on the relevant parameters in the UL grant. UE2 can also receive the transmission parameters from UE1, not necessarily the entire UL grant. UE2 can understand that the relevant parameters in the UL grant are based on the relevant configuration set of UE1. For example, the parameters for power control used by UE2 to transmit the data of UE1 can be determined based on the power control configuration set of UE1. The beam used by UE2 to transmit the data of UE1 can also be determined by the beam configuration of UE1, such as the beam used by UE1 to transmit the data. Therefore, UE2 can transmit the data instead of UE1 without being detected by the BS. That is, the data of UE1 can be transmitted based only on the power source of UE2. In this case, the BS still sees UE1 performing data transmission.

[0026] In some embodiments as described above, UE2 understands the relevant parameters in the UL transmission grant based on the configuration parameter set of UE1. For example, the BS can configure the respective power control values set for UE1 and indicate an index value in the UL transmission grant to select a specific power control value from the power control value set. However, UE2 can also be configured with another power control value set. When UE1 sends the index value in the UL transmission grant to UE2, UE2 can use the index value received from UE1 to select or determine a power control value from the power control value set of UE1 to transmit data from UE1. In this case, the power control value set configured by UE1 can be sent by UE1 to UE2. Alternatively or additionally, UE1 can directly send to UE2 the final parameter value calculated based on the configuration parameter set of UE1. For the power control value, UE1 can send to UE2 the information of the specific power control value determined.

[0027] Optionally, in some embodiments, UE1 can also continue to transmit data (already provided to UE2) in PUSCH according to the UL transmission grant, while UE2 also transmits UE1's data to the BS. Thus, UE1 and UE2 can transmit data in the same time-frequency resource in PUSCH at the same time, which helps to improve the reliability of data transmission. The BS can use data from both UE1 and UE2 at the same time to obtain better transmission quality.

[0028] Optionally, in some embodiments, two copies of data can be scheduled for UE1 in two PUSCHs by the UL transmission grant, UE1 can determine one copy of data and send it to UE2. UE2 can transmit the received data to the BS according to the above description.

[0029] The BS receives data in PUSCH according to the UL transmission grant. According to some embodiments, the BS can understand that the data belongs to UE1 regardless of whether the data is transmitted by UE1 or UE2. Since the BS does not need to know whether the data is actually sent by UE1, the existing BS can be reused without major modification. In these embodiments, because UE2 transmits data based on the UL transmission grant of UE1, the BS can understand that the data is transmitted by UE1 in PUSCH.

[0030] Semi-static transmission

[0031] According to some embodiments, UE1 can send UE1's Scheduling Request (SR) configuration information to UE2. If UE1 needs to send SR for uplink data, UE1 can inform UE2 of the relevant information of SR. UE2 can transmit SR PUCCH (Physical Uplink Control Channel) based on UE1's SR configuration information provided by UE1. For example, after UE1 informs UE2 to transmit SR on PUCCH, UE2 can generate SR sequence based on UE1's SR configuration information, and determine SR PUCCH resource based on UE1's SR configuration information. UE2 then transmits SR PUCCH based on the determined SR sequence and SR PUCCH resource. BS receives SR PUCCH based on UE1's SR configuration information, and BS identifies that these are UE1's uplink data, which need to be scheduled for transmission based on SR.

[0032] Alternatively or additionally, UE1 can also transmit SR PUCCH based on UE1's SR configuration information, so that UE1 and UE2 transmit the same SR sequence in the same SR PUCCH resource, thereby improving the coverage and performance of SR PUCCH.

[0033] According to some embodiments, UE1 can send UE1's Channel State Information (CSI) PUCCH configuration information to UE2. If UE1 needs to send CSI report, UE1 can provide UE2 with the relevant information of CSI report. UE2 can transmit CSI PUCCH based on UE1's CSI PUCCH configuration information provided by UE1. For example, after UE1 informs UE2 to transmit CSI PUCCH, UE2 can generate CSI report configuration based on UE1's CSI PUCCH configuration information, determine CSI PUCCH resource based on UE1's CSI PUCCH configuration information, and transmit CSI PUCCH based on the determined CSI report configuration and CSI PUCCH resource. BS receives CSI PUCCH based on UE1's CSI PUCCH configuration information, and BS identifies that this CSI PUCCH is transmitted by UE1.

[0034] Alternatively or additionally, UE1 can also transmit CSI PUCCH based on UE1's CSI PUCCH configuration information, so that UE1 and UE2 transmit the same CSI PUCCH in the same CSI PUCCH resource, thereby improving the coverage and performance of CSI PUCCH.

[0035] According to some embodiments, UE1 can send Sounding Reference Signal (SRS) configuration information of UE1 to UE2. If UE1 needs to send SRS, UE1 can inform UE2 of the relevant information of SRS. UE2 can transmit SRS based on the SRS configuration information of UE1. For example, after UE1 informs UE2 to transmit SRS, UE2 generates SRS sequence based on the SRS configuration information of UE1, determines SRS resource based on the SRS configuration information of UE1, and transmits SRS based on the determined SRS sequence and SRS resource. BS receives SRS based on the SRS configuration information of UE1, and BS considers that SRS is transmitted from UE1.

[0036] Alternatively or additionally, UE1 can also send SRS based on the SRS configuration information of UE1, so that UE1 and UE2 send the same SRS sequence in the same SRS resource, thereby improving the coverage and performance of SRS.

[0037] According to some embodiments, UE1 can send Configured Grant Physical Uplink Shared Channel (CG PUSCH) configuration information of UE1 to UE2. If UE1 needs to send data, UE1 can provide data to UE2. UE2 can transmit data based on the CG PUSCH configuration information of UE1. For example, after UE1 informs UE2 to transmit data, UE2 processes data into final transmission data based on the CG PUSCH configuration information of UE1, determines CG PUSCH resource based on the CG PUSCH configuration information of UE1, and transmits final data based on the determined CG PUSCH resource. BS receives data based on the CG PUSCH configuration information of UE1, and BS considers that CG PUSCH is transmitted from UE1.

[0038] Alternatively or additionally, UE1 can also send data based on the CG PUSCH configuration information of UE1, so that UE1 and UE2 send the same data in the same CG PUSCH resource, thereby improving the coverage and performance of data.

[0039] The above embodiments can improve the coverage of UE1 and improve the transmission performance of UE1. Alternatively or additionally, if the power of UE1 is limited, while UE2 is not, these methods help to extend the use time of UE1.

[0040] According to some embodiments of the present disclosure, the disclosed wireless communication method comprises: obtaining, by a second user equipment (UE), a transmission configuration corresponding to a first UE for transmitting data from the first UE; and transmitting, by the second UE, data to a base station (BS) according to the transmission configuration.

[0041] According to some embodiments, the wireless communication method can further comprise receiving, from the first UE, transmission configuration information, wherein the obtaining the transmission configuration comprises obtaining the transmission configuration based on the transmission configuration information.

[0042] According to some embodiments, the transmission configuration information comprises at least one of: an uplink (UL) transmission grant received by the first UE from the BS, resource information, modulation and coding scheme (MCS) information, beam information, layer number information, or power control information.

[0043] According to some embodiments, the obtaining the transmission configuration based on the transmission configuration information comprises selecting a configuration setting from a candidate setting set of the second UE based on the transmission configuration information.

[0051] determining, by the second UE based on the CG PUSCH configuration, data to be transmitted or a CG PUSCH resource; or

[0052] transmitting, by the second UE, data based on the CG PUSCH configuration.

[0053] According to some embodiments, the method of wireless communication can further include receiving, by the first UE or the second UE, an UL transmission grant indicating transmission configuration information configured for the second UE or configured based on an environment of the second UE.

[0054] According to some embodiments, the method of wireless communication can further include receiving, by the second UE from the BS or the first UE, an UL transmission grant indicating transmission configuration information or transmission configuration information configured for the second UE or configured based on an environment of the second UE.

[0055] According to some embodiments, the method of wireless communication can further include transmitting, by the second UE to the BS, data including transmitting, by the second UE, data simultaneously with the first UE.

[0056] According to some embodiments, a method of wireless communication is disclosed, comprising receiving, by a base station (BS), data of a first user equipment (UE) transmitted by a second UE according to a transmission configuration.

[0057] According to some embodiments, the method further includes transmitting, to the first UE or the second UE, transmission configuration information including at least one of: an uplink (UL) transmission grant, resource information, beam information, number of layers information, or power control information.

[0058] According to some embodiments, the method further includes receiving, from the second UE, a SR PUCCH transmitted based on at least one of: a SR sequence determined according to SR configuration information or a SR PUCCH resource;

[0059] receiving, from the second UE, a CSI PUCCH transmitted based on at least one of: a CSI report determined according to CSI PUCCH configuration information or a CSI PUCCH resource;

[0060] receiving, from the second UE, a SRS transmitted based on at least one of: a SRS sequence determined according to SRS configuration information or a SRS resource; or

[0061] receiving, from the second UE, data transmitted based on a CG PUSCH resource determined according to a CG PUSCH configuration.

[0062] Aggregated transmission with reported pairing information

[0063] Alternatively or additionally, according to some embodiments of the present disclosure, UE1 or UE2 can report the pairing information to the BS. The BS is thereby aware that UE1 and UE2 are paired for UE aggregated transmission. Here, UE1 and UE2 can be paired for UE aggregated transmission. UE1 receives UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1, and UE1 can use UE2 to transmit UE1’s data (including UCI information) to the BS. It can be assumed that UE1 and UE2 are paired for UL aggregated transmission, UE2 transmits UE1’s data to the BS, and the data interaction between UE1 and UE2 is timely.

[0064] In some embodiments, new Radio Resource Control (RRC) signaling can be introduced, which can be used by UE1 or UE2 to inform the BS that UE1 and UE2 are paired for aggregated transmission. Optionally, the RRC signaling can be used by UE1 or UE2 to further inform the BS that UE2 is used to transmit UE1’s data.

[0065] Dynamic scheduling of PUSCH by UL transmission grant

[0066] According to some embodiments, UE1 receives UL transmission grant from PDCCH, and the UL transmission grant schedules PUSCH to transmit UE1’s data. UE1 can send the data to be transmitted to UE2 according to the UL transmission grant. UE1 can also send the time-frequency resource information configured for PUSCH in the UL transmission grant to UE2. Optionally, UE1 can also send the UL transmission grant to UE2. UE2 can transmit the data from UE1 according to the information of the UL transmission grant. Alternatively or additionally, UE1 can only send the information necessary for PUSCH transmission in the UL transmission grant. For example, the information includes at least one of resource information (including at least one of PRB information, symbol information, slot information, or carrier information carrying PUSCH), beam information, number of layers information, or power control related information. The carrier used by UE1 to send data to UE2 can be the same or different from the carrier used by UE2 to transmit PUSCH.

[0067] According to some embodiments, UE2 receives data and UL transmission grant from UE1, and UE2 transmits the data based on the relevant parameters in the UL transmission grant. Additionally or alternatively, UE2 can only receive the relevant parameters required for UL transmission. UE2 understands the relevant parameters in the UL transmission grant based on the relevant configuration set of UE2. For example, the parameters for power control used by UE2 to transmit data from UE1 can be determined based on the power control configuration set of UE2. The beam used by UE2 to transmit data can also be the beam used by UE2 to transmit data.

[0068] According to some embodiments, UE2 receives UL grant from UE1 and transmits data from UE1. Here, the UL transmission grant can be configured and sent by BS to UE1, but the values of the related parameters in the UL grant are configured based on the parameter value set of UE2, which can improve the transmission efficiency because the values of these related parameters better match the channel environment of UE2, which is the device transmitting the data. In this case, because BS understands that UE2 transmits data from UE1, BS can configure the related parameters in the UL transmission grant received by UE1 based on the channel environment of UE2.

[0069] Configuration of related parameters of UL transmission grant

[0070] Since BS knows that UE2 transmits data of UE1, BS can configure some related parameters in the UL transmission grant based on the channel environment of UE2. Therefore, UE1 receives the UL transmission grant, but some or all of the related parameters in the UL transmission grant are configured for UE2 based on the environment of UE2, not for UE1. These parameters can mainly include parameters related to UL transmission, such as at least one of the following: modulation and coding scheme (MCS) information, receive / transmit beam information, layer number information, power control parameters, or time-frequency resource information. BS can configure or agree with UE which parameters in the UL transmission grant are configured for UE1 and which parameters are configured for UE2. The layer number can indicate the number of layers used to transmit data. For example, if two layers are used to transmit data, two data blocks can be transmitted simultaneously. The two layers can use the same time-frequency resources.

[0071] Optionally, BS can configure the same set of time-frequency resources (such as Time Domain Resource Allocation (TDRA) table and Frequency Domain Resource Allocation (FDRA) table) for UE1 and UE2, so that UE1 and UE2 can obtain the same time-frequency resources from the respective sets of time-frequency resources based on the time domain resource allocation indication index and the frequency domain resource allocation indication index in the UL transmission grant. Optionally, BS can configure the same set of MCSs for UE1 and UE2, so that UE1 and UE2 can obtain the same MCS parameters from the respective sets of MCSs based on the MCS index in the UL transmission grant. In this way, if UE1 also transmits the same data as UE2, the same time-frequency resources and MCS can be used to recover the received data, achieving additional gain.

[0072] Optionally, in the UL transmission grant, some parameters can be configured into multiple groups respectively, each group can correspond to a UE in the paired group. For example, for the paired UE1 and UE2, the parameter configuration in the UL transmission grant can include at least one of the following: two groups of MCS parameters, two groups of layer parameters, two groups of power control parameters, two groups of TDRA parameters, two groups of FDRA parameters, two groups of beam information, etc. Each group can be configured for UE1 or UE2. For example, the first group of the above parameters is used for UE1, and the second group of the above parameters is used for UE2. After UE1 receives the UL transmission grant, UE1 can send the second group of parameters to UE2. UE1 can send first data to the BS based on the first group of parameters. UE2 can send second data to the BS based on the second group of parameters. It should be noted that the second data sent by UE2 comes from UE1.

[0073] Alternatively or additionally, UE1 can send second data to UE2, and UE2 sends second data to the BS based on the second group of parameters. The UE can also send first data to the BS based on the first group of parameters.

[0074] Alternatively or additionally, it can also be determined whether the first data and the second data are the same according to the signaling indication from the BS. The signaling indication can be configured in the UL transmission grant or RRC signaling.

[0075] Alternatively or additionally, UE1 can also optionally continue to transmit data in PUSCH according to the UL transmission grant. In this way, UE1 and UE2 transmit data in the same time-frequency resource in PUSCH at the same time, which helps to improve the reliability of transmission.

[0076] Alternatively or additionally, optionally, two copies of data are scheduled for UE1 in two PUSCHs through the UL transmission grant, and UE1 can determine one copy of data and send the determined copy to UE2. Then, UE2 can transmit the received copy to the BS according to the above method.

[0077] Correspondingly, the BS can receive data in PUSCH from UE1 and / or UE2 according to the related parameters in the UL transmission grant. For example, the BS receives the data of UE1 from UE2, and transmits the data based on the beam information of UE2. When UE2 transmits data instead of UE1, the relevant parameters (such as MCS, beam information, etc.) corresponding to the channel environment of UE2 can be used as much as possible to ensure the transmission performance.

[0078] Semi-static transmission

[0079] In the case where UE1 and / or UE2 report to the BS that UE1 and UE2 are paired for aggregated transmission and UE2 transmits data from UE1, the BS knows that UE1 and UE2 are paired.

[0080] Additionally or alternatively, the BS can provide UE2 with scheduling request (SR) configuration information of UE1. For example, a UE ID can be introduced in the existing SR configuration information, which indicates the UE associated with the SR configuration information. The UE ID can be used in paired UEs to achieve smaller signaling overhead. For example, if two UEs are paired for UE aggregated transmission, the UE ID can be 1 bit, and different values of the 1 bit correspond to one of the two paired UEs. Alternatively or additionally, if UE1 or UE2 reports pairing information to the BS and UE2 transmits data of UE1, the BS can configure SR configuration information for UE2. UE2 can consider the SR configuration information to be for UE1 paired with UE2.

[0081] In some embodiments, if UE1 needs to transmit a scheduling request (SR) for uplink data, UE1 can provide UE2 with relevant information of the SR. UE2 transmits an SR PUCCH according to the SR configuration information of UE1. For example, after UE1 informs UE2 to transmit the SR PUCCH, UE2 generates an SR sequence based on the SR configuration information of UE1, determines an SR PUCCH resource based on the SR configuration information of UE1, and transmits the SR PUCCH based on the determined SR sequence and SR PUCCH resource. The BS receives the SR PUCCH based on the SR configuration information of UE1, and the BS identifies that it is uplink data of UE1 that needs to be scheduled.

[0082] Optionally or additionally, UE1 can also transmit the SR PUCCH based on the SR configuration information of UE1, so that UE1 and UE2 can transmit the same SR sequence in the same SR PUCCH resource, thereby improving the coverage and performance of the SR PUCCH.

[0083] In some embodiments, the BS can provide UE2 with CS IPUCCH configuration information of UE1. A UE ID can be introduced in the existing CS IPUCCH configuration information. The UE ID indicates the UE associated with the CS IPUCCH configuration information. The UE ID can be used in paired UEs to achieve smaller signaling overhead. For example, if two UEs are paired for UE aggregated transmission, the UE ID can be 1 bit, and different values of the 1 bit correspond to one of the two paired UEs. Alternatively or additionally, if UE1 or UE2 reports pairing information to the BS and UE2 transmits data of UE1, the BS can configure CS IPUCCH configuration information for UE2. UE2 can consider the CS IPUCCH configuration information to be for UE1 paired with UE2.

[0084] In some embodiments, if UE1 needs to send a CSI report, UE1 provides UE2 with relevant information of the CSI report. UE2 can transmit a CSI PUCCH based on the CSI PUCCH configuration information of UE1. For example, after UE1 informs UE2 to transmit a CSI PUCCH, UE2 generates a CSI report based on the CSI PUCCH configuration information of UE1, determines a CSI PUCCH resource based on the CSI PUCCH configuration information of UE1, and transmits a CSI PUCCH based on the determined CSI report and CSI PUCCH resource. The BS receives the CSI PUCCH based on the CSI PUCCH configuration information of UE1, and the BS considers that the CSI PUCCH is transmitted by UE1.

[0085] Alternatively or additionally, UE1 can also send a CSI PUCCH based on the CSI PUCCH configuration information of UE1, so that UE1 and UE2 send the same CSI PUCCH in the same CSI PUCCH resource, thereby improving the coverage and performance of the CSI PUCCH.

[0086] In some embodiments, the BS provides UE2 with SRS configuration information of UE1. Alternatively or additionally, a UE ID can be introduced in the existing SRS configuration information, which indicates the UE associated with the SRS configuration information. The UE ID can be designed in paired UEs to obtain a smaller signaling overhead. For example, if two UEs are paired for UE aggregation transmission, the UE ID can be 1 bit, and different values of 1 bit correspond to one of the two paired UEs. Alternatively or additionally, if UE1 or UE2 reports pairing information to the BS and UE2 transmits data of UE1, the BS configures SRS configuration information for UE2. UE2 considers that the SRS configuration information is for UE1 paired with UE2.

[0087] In some embodiments, if UE1 needs to send a SRS, UE1 provides UE2 with relevant information of the SRS. UE2 transmits a SRS according to the SRS configuration information of UE1. For example, after UE1 informs UE2 to transmit a SRS, UE2 generates a SRS sequence based on the SRS configuration information of UE1, determines a SRS resource based on the SRS configuration information of UE1, and transmits a SRS based on the determined SRS sequence and SRS resource. The BS receives the SRS based on the SRS configuration information of UE1, and the BS considers that the SRS is transmitted from UE1.

[0088] Alternatively or additionally, UE1 can also send a SRS based on the SRS configuration information of UE1, so that UE1 and UE2 send the same SRS sequence in the same SRS resource, thereby improving the coverage and performance of the SRS.

[0089] In some embodiments, the BS provides the UE2 with the CG PUSCH configuration information of the UE1. Alternatively or additionally, a UE ID can be introduced in the existing CG PUSCH configuration information. The UE ID indicates the UE associated with the CG PUSCH configuration information. The UE ID can be designed in paired UEs to obtain a smaller signaling overhead. For example, if two UEs are paired for UE aggregated transmission, the UE ID can be 1 bit, and different values of 1 bit correspond to one of the two paired UEs. Alternatively or additionally, if the UE1 or the UE2 reports the pairing information to the BS and the UE2 transmits the data of the UE1, the BS can configure the CG PUSCH configuration information for the UE2. The UE2 considers the CG PUSCH configuration information to be for the UE1 paired with the UE2.

[0090] In some embodiments, if the UE1 needs to transmit data, the UE1 provides the data to the UE2. The UE2 transmits the data according to the CG PUSCH configuration information of the UE1. For example, after the UE1 informs the UE2 to transmit the data, the UE2 processes the data into final transmission data based on the CG PUSCH configuration information of the UE1, determines the CG PUSCH resource based on the CG PUSCH configuration information of the UE1, and transmits the final data based on the determined CG PUSCH resource. The BS receives the data based on the CG PUSCH configuration information of the UE1, and the BS considers the CG PUSCH to be transmitted from the UE1.

[0091] Alternatively or additionally, the UE1 can also transmit the data based on the CG PUSCH configuration information of the UE1, so that the UE1 and the UE2 transmit the same data in the same CG PUSCH resource, thereby improving the coverage and performance of the data.

[0092] In the above manner, the coverage of the UE1 can be improved, and the transmission performance of the UE1 can be improved.

[0118] UL transmission grant for UE2

[0119] According to some embodiments of the present disclosure, UE1 and UE2 are paired for UE aggregated transmission, and UE2 can transmit data (including uplink control information (UCI)) received from UE1 to the BS. UE2 can receive an UL transmission grant (or DCI) for UE1; for example, the UL transmission grant can be transmitted by the BS to UE2. UE1 or UE2 can report pairing information to the BS, so the BS knows that UE1 and UE2 are paired for UE aggregated transmission. The UL transmission grant, such as DCI (downlink control information), is generally used to schedule PUSCH, and can be transmitted in PDCCH (physical downlink control channel) in resources corresponding to PDCCH configuration information.

[0120] According to some embodiments of the present disclosure, the BS or UE1 can provide the UL transmission grant associated with data transmission of UE1 to UE2. The BS can also provide the UL transmission grant associated with data transmission of UE2 to UE2. At least one of a cell radio network temporary identifier (C-RNTI) associated with UE1 or transmission of UE1 data, a C-RNTI associated with UE2 or transmission of UE2 data, PDCCH configuration information associated with UE1 or transmission of UE1, or PDCCH configuration information associated with UE2 or transmission of UE2, or PDCCH resources used to transmit the UL transmission grant can be used to determine whether the UL transmission grant is configured for transmitting data from UE1 or data originating from UE2. In addition, the C-RNTI or the PDCCH configuration information can be configured by the UE or the BS.

[0121] UE configured C-RNTI and PDCCH configuration information

[0122] In some embodiments, UE1 or UE2 can report pairing information to the BS, so the BS knows that UE1 and UE2 are paired for UE aggregated transmission. UE1 and UE2 are paired for UE aggregated transmission, and UE2 can transmit data (including uplink control information (UCI)) received from UE1 to the BS.

[0123] In these embodiments, UE1 informs UE2 of UE1's C-RNTI (Cell Radio Network Temporary Identifier) and UE1's PDCCH configuration information. UE2 can detect UL transmission grant for UE1 in the resources corresponding to UE1's PDCCH configuration information based on UE1's C-RNTI.

[0124] The BS can transmit UL transmission grant scrambled with UE1's C-RNTI in the resources corresponding to UE1's PDCCH configuration information, but configured for UE2 and / or configure parameters in the UL transmission grant (such as at least one of MCS, time-frequency resource configuration, beam information, power control information, or number of layers) based on UE2's environment. Where the data corresponding to the UL transmission grant is UE1's data, and UE2 is configured to transmit the data to the BS. The UL transmission grant for UE1 can be received by UE2 from the BS.

[0125] In these embodiments, UE2 detects UL transmission grant in the resources corresponding to UE1's PDCCH configuration information based on UE1's C-RNTI. After UE2 detects UL transmission grant scrambled with UE1's C-RNTI, UE2 requests UE1 for data to be transmitted corresponding to the UL transmission grant. UE1 sends the corresponding data to UE2, and UE2 transmits the data to the BS based on the UL transmission grant. For example, UE2 determines values of relevant parameters for transmitting the data from UE2's corresponding configuration set based on the parameters in the UL transmission grant.

[0126] Additionally or alternatively, UE1 can also detect UL transmission grant in the resources corresponding to UE1's PDCCH configuration information based on UE1's C-RNTI. UE1 can also transmit data based on the UL transmission grant, such that both UE1 and UE2 send data to the BS.

[0127] UE-configured C-RNTI and BS-configured PDCCH configuration information

[0128] In some embodiments, UE1 or UE2 can report pairing information to the BS, such that the BS knows that UE1 and UE2 are paired for UE aggregated transmission. UE1 and UE2 are paired for UE aggregated transmission, and UE2 can send data (including uplink control information (UCI)) received from UE1 to the BS. The BS receives the reported pairing information from UE1 or UE2. The BS knows that UE1 and UE2 are paired for UE aggregated transmission, and UE2 sends data from UE1 to the BS.

[0129] In these embodiments, UE1 informs UE2 of UE1's C-RNTI (but not necessarily PDCCH configuration information). UE2 can detect UL transmission grant for UE1 in the resource corresponding to UE1's PDCCH configuration information based on UE1's C-RNTI. On the other hand, BS configures / informs UE2 of UE1's PDCCH configuration information. BS can transmit UL transmission grant scrambled with UE1's C-RNTI in the resource corresponding to UE1's PDCCH configuration information, but configure (instead of UE1) parameters (such as at least one of MCS, time-frequency resource configuration, beam information, power control information, or number of layers) in UL transmission grant for UE2. Data corresponding to UL transmission grant is data for UE1.

[0130] In these embodiments, BS configures UE1's PDCCH configuration information to UE2. Additionally or alternatively, BS configures PDCCH configuration information for UE2, and the configured PDCCH configuration information (or resource corresponding to the configured PDCCH configuration information) is the same as or different from UE1's PDCCH configuration information (or resource corresponding to UE1's PDCCH configuration information). UE2 detects UL transmission grant in the resource corresponding to the configured PDCCH configuration information based on the configured C-RNTI.

[0131] From UE2's perspective, UE2 considers the configured PDCCH configuration information to be used to receive UL transmission grant corresponding to UE1 for UE aggregation transmission. The configured PDCCH configuration information (or resource corresponding to the configured PDCCH configuration information) can be the same as or different from UE2's PDCCH configuration information (or resource corresponding to UE2's PDCCH configuration information).

[0132] Alternatively or additionally, the BS can configure PDCCH configuration information for UE2 (optionally label the PDCCH configuration information as index 0, and for the PDCCH resource, optionally label the corresponding PDCCH resource as PDCCH resource 0). In PDCCH resource 0, the BS can transmit UL transmission grant scrambled by the C-RNTI of UE2, which UE2 can receive from PDCCH resource 0 based on the C-RNTI of UE2. According to some embodiments, improvements can be introduced to support UE aggregated transmission. New PDCCH configuration information and / or PDCCH resource can be introduced. UE can use the PDCCH resource / configuration information used to transmit the UL transmission grant to determine whether the UL transmission grant is associated with the transmission of data of UE1 or the transmission of data of UE2. For example, if the BS receives the pairing information of UE1 and UE2 from UE1 or UE2, the BS can configure additional PDCCH configuration information for UE2 (optionally label the PDCCH configuration information as index 1, and optionally label the corresponding PDCCH resource as PDCCH resource 1). In PDCCH resource 1, the BS can transmit UL transmission grant scrambled by the C-RNTI of UE2, which UE2 can receive in PDCCH resource 1 based on the C-RNTI of UE2. UE2 understands that the UL grant in PDCCH resource 1 is for UE2 to transmit data from UE1. UE2 can understand that the UL grant in PDCCH resource 0 is for UE2 to transmit data from UE2. In this mechanism, UE2 can receive UL transmission grant associated with UE1 based on the C-RNTI of UE2 instead of the C-RNTI of UE1. UE2 can determine whether the UL transmission grant is for UE2 to transmit data of UE1 or to transmit data of UE2 according to whether the UL transmission grant is received from PDCCH resource 0 or PDCCH resource 1. UE2 does not need to have the C-RNTI of UE1 for UL transmission grant, thus improving the security of the system. Here, PDCCH configuration information 1 and PDCCH configuration information 0 can be the same or different, and PDCCH resource 1 and PDCCH resource 0 can be the same or different. If the same, the UL transmission grant in PDCCH resource 0 and the UL transmission grant in PUCCH resource 1 can be transmitted from different base stations (or other network nodes similar to base stations, such as relay stations). Here, because UE2 can use the source of the UL transmission grant to determine whether the UL transmission grant is configured for UE2 to transmit data of UE1 or to transmit data of UE2.

[0133] Further, if PDCCH configuration information 1 is not configured for UE2, the BS and UE2 can agree that PDCCH resource 0 is used by UE2 to receive UL grant based on UE2's C-RNTI, but the UL transmission grant is used by UE2 to transmit data from UE1. PDCCH resource 0 can be used when UE2 does not need to transmit data from UE2. Alternatively, if PDCCH configuration information 1 is not configured for UE2, the BS and UE2 can agree that PDCCH resource 0 is used by UE2 to receive UL transmission grant based on UE2's C-RNTI, but the UL grant is used by UE2 to transmit data from UE2 only. It can be used when the BS does not want to support aggregated transmission of UE1 and UE2.

[0134] UE2 detects UL transmission grant based on UE1's C-RNTI in the resource corresponding to UE1's PDCCH configuration information. After UE2 detects UL transmission grant scrambled with UE1's C-RNTI, UE2 requests UE1 for the data to be transmitted corresponding to the UL transmission grant. Then, UE1 sends the corresponding data to UE2, and UE2 transmits the data based on the UL transmission grant. For example, UE2 determines the values of the relevant parameters for transmitting the data from the corresponding configuration set of UE2 based on the parameters in the UL transmission grant.

[0135] Alternatively or additionally, UE1 can also detect UL transmission grant based on UE1's C-RNTI in the resource corresponding to UE1's PDCCH configuration information. UE1 can also transmit data based on the UL transmission grant. That is, both UE1 and UE2 send data to the BS.

[0136] UE-configured C-RNTI

[0137] In some embodiments, UE1 or UE2 can report pairing information to the BS, so that the BS knows that UE1 and UE2 are paired for UE aggregated transmission. UE1 and UE2 are paired for UE aggregated transmission, and UE2 can send data (including uplink control information (UCI)) received from UE1 to the BS.

[0138] Additionally or alternatively, UE1 informs UE2 of UE1's C-RNTI (but not necessarily PDCCH configuration information). UE2 can detect UE1's UL transmission grant based on UE1's C-RNTI in the resource corresponding to UE2's PDCCH configuration information.

[0139] In these embodiments, the BS can not configure the PDCCH configuration information of UE1 to UE2. The BS can transmit an UL transmission grant scrambled by the C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE2, and configure the parameters in the UL transmission grant (such as at least one of MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) for UE2. The data corresponding to the UL transmission grant is the data of UE1.

[0140] Additionally or alternatively, the BS can also send an UL transmission grant scrambled by the C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE1, and the UL transmission grant also schedules data transmission. The data scheduled by the UL transmission grant can be the same as or different from the data of UE1 transmitted by UE2, and the UL transmission grant can be the same as or different from the UL transmission grant sent by UE1 in the resource corresponding to the PDCCH configuration information of UE2.

[0141] Additionally or alternatively, UE2 can detect the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE2 based on the C-RNTI of UE1. After UE2 detects the UL transmission grant scrambled by the C-RNTI of UE1, UE2 requests the data to be transmitted corresponding to the UL transmission grant from UE1. UE1 sends the corresponding data to UE2, and UE2 transmits the data based on the UL transmission grant. For example, UE2 determines the values of the relevant parameters for transmitting data from the corresponding configuration set of UE2 based on the parameters in the UL transmission grant.

[0142] Additionally or alternatively, UE1 can also detect the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. UE1 can also transmit data based on the UL transmission grant. That is, both UE1 and UE2 send data to the BS. The data scheduled by the UL transmission grant can be the same as or different from the data of UE1 transmitted by UE2, and the UL transmission grant can be the same as or different from the UL transmission grant sent by UE in the resource corresponding to the PDCCH configuration information of UE2.

[0143] PDCCH configuration information configured by UE and C-RNTI configured by BS

[0144] In some embodiments, UE1 and UE2 are paired for UE aggregated transmission, and UE2 can send data (also including uplink control information (UCI)) from UE1 to the BS. UE1 or UE2 reports pairing information to the BS, so that the BS knows that UE1 and UE2 are paired for UE aggregated transmission, and UE2 sends data from UE1 to the BS.

[0145] In these embodiments, UE1 informs UE2 of the PDCCH configuration information of UE1. UE2 can detect UL transmission grant for UE1 in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1.

[0146] The BS configures the C-RNTI of UE1 to UE2. The BS can transmit UL transmission grant scrambled with the C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE1, but configures parameters (such as MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) in the UL transmission grant for UE2. The data corresponding to the UL transmission grant must be the data of UE1.

[0147] The BS configures the C-RNTI of UE1 to UE2. Additionally or alternatively, the BS configures a C-RNTI for UE2. The configured C-RNTI is the same as or different from the C-RNTI of UE1, and UE2 detects UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the configured C-RNTI. Other processes are the same as described above. From the perspective of UE2, UE2 considers that the configured C-RNTI is used to receive UL transmission grant corresponding to UE1, and UE1 is paired with UE2 to perform UE aggregated transmission.

[0148] UE2 detects UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. After UE2 detects the UL transmission grant scrambled with the C-RNTI of UE1, UE2 requests the data to be transmitted corresponding to the UL transmission grant from UE1. UE1 sends the corresponding data to UE2, and UE2 transmits the data based on the UL transmission grant. For example, UE2 determines the values of the relevant parameters for transmitting data from the corresponding configuration set of UE2 based on the parameters in the UL transmission grant.

[0149] Additionally or alternatively, UE1 can also detect UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. UE1 can also transmit data based on the UL transmission grant. That is, both UE1 and UE2 send data to the BS.

[0150] C-RNTI and PDCCH configuration information configured by the BS

[0151] In some embodiments, UE1 and UE2 are paired for UE aggregated transmission, and UE2 can send data (also including uplink control information (UCI)) from UE1 to the BS. UE1 or UE2 reports pairing information to the BS. The BS knows that UE1 and UE2 are paired for UE aggregated transmission, and UE2 sends data from UE1 to the BS.

[0152] In these embodiments, UE2 receives UL transmission grant of UE1 in the resource corresponding to the PDCCH configuration information configured by the BS based on the C-RNTI configured by the BS.

[0153] The base station configures the C-RNTI of UE1 and the PDCCH configuration information of UE1 to UE2. The BS can transmit UL transmission grant scrambled with the C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE1, but configures the parameters (such as MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) in the UL transmission grant for UE2. The data corresponding to the UL transmission grant must be the data of UE1.

[0154] In these embodiments, the BS configures the C-RNTI of UE1 to UE2. Alternatively or additionally, the BS configures the C-RNTI for UE2, and the configured C-RNTI is the same as or different from the C-RNTI of UE1. UE2 detects the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the configured C-RNTI. Other processes are the same as described above. From the perspective of UE2, UE2 considers that the configured C-RNTI is used to receive the UL transmission grant corresponding to UE1, and UE1 is paired with UE2 to perform UE aggregated transmission.

[0155] In these embodiments, the BS configures the PDCCH configuration information of UE1 to UE2. Alternatively or additionally, the BS configures the PDCCH configuration information for UE2, and the configured PDCCH configuration information (or the resource corresponding to the configured PDCCH configuration information) is the same as or different from the PDCCH configuration information of UE1 (or the resource corresponding to the PDCCH configuration information of UE1). UE2 detects the UL transmission grant in the resource corresponding to the configured PDCCH configuration information based on the configured C-RNTI. From the perspective of UE2, UE2 considers that the configured PDCCH configuration information is used to receive the UL transmission grant corresponding to UE1. The configured PDCCH configuration information (or the resource corresponding to the configured PDCCH configuration information) can be the same as or different from the PDCCH configuration information of UE2 (or the resource corresponding to the PDCCH configuration information of UE2).

[0156] Alternatively or additionally, the BS can configure PDCCH configuration information for UE2 (optionally label the PDCCH configuration information as index 0, and for the PDCCH resource, optionally label the corresponding PDCCH resource as PDCCH resource 0). In PDCCH resource 0, the BS can transmit UL transmission grant scrambled by the C-RNTI of UE2, which UE2 can receive from PDCCH resource 0 based on the C-RNTI of UE2. According to some embodiments, improvements can be introduced to support UE aggregated transmission. New PDCCH configuration information and / or PDCCH resource can be introduced. UE can use the PDCCH resource / configuration information used to transmit the UL transmission grant to determine whether the UL transmission grant is associated with the transmission of data of UE1 or the transmission of data of UE2. For example, if the BS receives the pairing information of UE1 and UE2 from UE1 or UE2, the BS can configure additional PDCCH configuration information for UE2 (optionally label the PDCCH configuration information as index 1, and optionally label the corresponding PDCCH resource as PDCCH resource 1). In PDCCH resource 1, the BS can transmit UL transmission grant scrambled by the C-RNTI of UE2, which UE2 can receive in PDCCH resource 1 based on the C-RNTI of UE2. UE2 understands that the UL grant in PDCCH resource 1 is for UE2 to transmit data from UE1. UE2 can understand that the UL grant in PDCCH resource 0 is for UE2 to transmit data from UE2.

UE2 can determine whether the UL transmission grant is for UE2 to transmit data of UE1 or to transmit data of UE2 according to whether the UL transmission grant is received from PDCCH resource 0 or PDCCH resource 1. UE2 does not need to have the C-RNTI of UE1 for UL transmission grant, thus improving the security of the system. Here, PDCCH configuration information 1 and PDCCH configuration information 0 can be the same or different, and PDCCH resource 1 and PDCCH resource 0 can be the same or different. If the same, the UL transmission grant in PDCCH resource 0 and the UL transmission grant in PUCCH resource 1 can be transmitted from different base stations (or other network nodes similar to base stations, such as relay stations). Here, because UE2 can use the source of the UL transmission grant to determine whether the UL transmission grant is configured for UE2 to transmit data of UE1 or to transmit data of UE2.

[0157] Further, if PDCCH configuration information 1 is not configured for UE2, the BS and UE2 can agree that PDCCH resource 0 is used by UE2 to receive UL grant based on C-RNTI of UE2, but the UL transmission grant is used by UE2 to transmit data from UE1. PDCCH resource 0 can be used when UE2 does not need to transmit data from UE2. Alternatively, if PDCCH configuration information 1 is not configured for UE2, the BS and UE2 can agree that PDCCH resource 0 is used by UE2 to receive UL transmission grant based on C-RNTI of UE2, but the UL grant is used by UE2 to transmit data from UE2 only. It can be used when the BS does not want to support aggregated transmission of UE1 and UE2.

[0158] In various embodiments of the present disclosure, the BS can transmit UL transmission grant scrambled with configured C-RNTI in the resource corresponding to the configured PDCCH configuration information, but configure parameters in the UL transmission grant (such as MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) for UE2 (for transmitting data of UE1).

UE2 receives the UL transmission grant in the resource corresponding to the configured PDCCH configuration information based on the configured C-RNTI, and UE2 can also receive the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE2 based on the C-RNTI of UE2.

[0159] Optionally, in some embodiments, the base station can also send UL transmission grant scrambled with C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE1, and the UL transmission grant also schedules data transmission. Here, the data scheduled by the UL transmission grant is the same as or different from the data of UE1 transmitted by UE2, and the UL transmission grant is the same as or different from the UL transmission grant sent by UE in the resource corresponding to the PDCCH configuration information of UE2.

[0160] In some embodiments, UE2 detects the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. After UE2 detects the UL transmission grant scrambled with the C-RNTI of UE1, UE2 requests the data to be transmitted corresponding to the UL transmission grant from UE1. UE1 sends the corresponding data, and UE2 transmits the data based on the UL transmission grant. For example, UE2 determines the values of the relevant parameters for transmitting data from the corresponding configuration set of UE2 based on the parameters in the UL transmission grant.

[0161] In some embodiments, UE1 can also detect a UL transmission grant in the resources corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. UE1 can also transmit data based on the UL transmission grant. That is, both UE1 and UE2 transmit data to the BS. The data scheduled by the UL transmission grant can be the same or different from the data of UE1 transmitted by UE2, and the UL transmission grant can be the same or different from the UL transmission grant transmitted by UE2 in the resources corresponding to the PDCCH configuration information of UE2.

[0162] C-RNTI configured by the BS

[0163] In some embodiments, UE1 and UE2 are paired for UE aggregated transmission, and UE2 can transmit data (also including uplink control information (UCI)) from UE1 to the BS. UE1 or UE2 reports the pairing information to the BS. The BS knows that UE1 and UE2 are paired for UE aggregated transmission, and UE2 transmits data from UE1 to the BS.

[0164] In these embodiments, UE2 receives a UL transmission grant of UE1 in the resources corresponding to the PDCCH configuration information of UE2 based on the C-RNTI configured by the BS.

[0165] The BS configures the C-RNTI of UE1 to UE2. The BS can transmit a UL transmission grant scrambled with the C-RNTI of UE1 in the resources corresponding to the PDCCH configuration information of UE2, but configures parameters (such as MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) in the UL transmission grant for UE2.

Alternatively or additionally, the BS configures a C-RNTI for UE2, and the configured C-RNTI is the same as or different from the C-RNTI of UE1. UE2 detects a UL transmission grant in the resources corresponding to the PDCCH configuration information of UE1 based on the configured C-RNTI. From the perspective of UE2, UE2 considers that the configured C-RNTI is used to receive the UL transmission grant corresponding to UE1, and UE1 is paired with UE2 to perform UE aggregated transmission. The configured C-RNTI can be the same as or different from the C-RNTI of UE2.

[0167] Correspondingly, in these embodiments, the BS can transmit an UL transmission grant scrambled with the configured C-RNTI in the resource corresponding to the PDCCH configuration information of UE2, but configure parameters (such as MCS, time-frequency resource configuration, beam information, power control information, number of layers, etc.) in the UL transmission grant for UE2, and the data corresponding to the UL transmission grant is the data of UE1. UE2 receives the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE2 based on the configured C-RNTI. UE2 also receives the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE2 based on the C-RNTI of UE2.

[0168] Optionally, the BS can also send an UL transmission grant scrambled by the C-RNTI of UE1 in the resource corresponding to the PDCCH configuration information of UE1, and the UL transmission grant also schedules data transmission. The data scheduled by the UL transmission grant is the same as or different from the data of UE1 transmitted by E2, and the UL transmission grant is the same as or different from the UL transmission grant sent by the UE in the resource corresponding to the PDCCH configuration information of UE2.

[0169] Additionally or alternatively, UE2 detects the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE2 based on the C-RNTI of UE1. After UE2 detects the UL transmission grant scrambled by the C-RNTI of UE1, UE2 requests the data corresponding to the UL transmission grant from UE1. UE1 sends the corresponding data to UE2, and UE2 transmits the data based on the UL transmission grant. For example, UE2 determines the values of the relevant parameters for transmitting data from the corresponding configuration set of UE2 based on the parameters in the UL transmission grant.

[0170] Additionally or alternatively, UE1 can also detect the UL transmission grant in the resource corresponding to the PDCCH configuration information of UE1 based on the C-RNTI of UE1. UE1 can also transmit data based on the UL transmission grant. That is, UE1 and UE2 both send data to the BS. The data scheduled by the UL transmission grant is the same as or different from the data of UE1 transmitted by E2, and the UL transmission grant is the same as or different from the UL transmission grant sent by the UE in the resource corresponding to the PDCCH configuration information of UE2.

[0188] Various exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings to enable one of ordinary skill in the art to make and use the present disclosure. The present disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Additionally, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary approaches. Based on the description herein, a person of ordinary skill in the art would understand that the specific order or hierarchy of steps in the methods disclosed herein could be rearranged, while still falling within the scope of the present disclosure. Accordingly, those skilled in the art will appreciate that the methods and techniques disclosed herein present various steps or acts in an exemplary order and that the present disclosure is not limited to the specific order or hierarchy presented unless explicitly stated otherwise.

[0189] The present disclosure is intended to cover any conceivable variations, uses, combinations or adaptations of the present disclosure following the general principles thereof and including knowledge and technical means known in the art and not disclosed in the present application.

[0190] It is to be understood that the present disclosure is not limited to the precise structures or operations described above and illustrated in the drawings, and that various modifications and changes can be made without departing from the scope of the present application. The scope of the present application is limited only by the claims appended hereto.

[0191] The methods, devices, processes, circuits and logic described above can be implemented in many different ways and in many different combinations of hardware and software. For example, all or parts of the implementation can be circuitry that includes a processor or controller (such as a Central Processing Unit (CPU), microcontroller, or microprocessor); or an Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or Field Programmable Gate Array (FPGA); or it can be circuitry that includes discrete components, including analog components, digital components, or both; or it can be any combination of such hardware components. As an example, the circuitry can include discrete interconnected hardware components, or can be combined in a single integrated circuit chip or distributed among multiple integrated circuit chips, or implemented in a Multi-Chip Module (MCM) that includes multiple integrated circuit chips in a common enclosure.

[0192] Accordingly, the circuitry can store or access instructions for execution, and can implement its functionality through hardware alone or in combination with software. The instructions can be stored in a tangible storage medium, such as a flash memory, a Random Access Memory (RAM), a Read-Only Memory (ROM), an Erasable Programmable Read-Only Memory (EPROM), or other memory devices, or on a magnetic or optical disk, such as a Compact Disc Read-Only Memory (CDROM), an optical disk drive, or other disk storage device. The instructions can also be stored or accessed on another machine-readable medium, or on a machine-readable storage medium that is not a transitory signal. A product, such as a computer program product, can include a storage medium and storage medium having stored therein instructions, and can store the instructions on the medium or on another medium that is readable by a machine. The instructions can cause the device to carry out any of the processes described or illustrated above when executed by the circuitry of the device.

[0193] These implementations can be distributed. For example, a circuit can include multiple different system components, such as multiple processors and memories, and can span multiple distributed processing systems. Parameters, databases, and other data structures can be stored and managed separately, can be combined into a single memory or database, can be logically and physically organized in many different ways, and can be implemented in many different ways. Exemplary implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records), objects, and implicit storage mechanisms. Instructions can form part of a single program (e.g., a subroutine or other code segment), can form multiple separate programs, can be distributed across multiple memories and processors, and can be implemented in many different ways. Exemplary implementations include standalone programs, and as part of a library, such as a shared library like a Dynamic Link Library (DLL). For example, a library can contain shared data and one or more shared programs that contain instructions that, when executed by a circuit, perform any of the processes described above or illustrated in the figures.

[0194] In some embodiments, each unit, sub-unit, and / or module of the system can include a logical component. Each logical component can be hardware or a combination of hardware and software. For example, each logical component can include an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), digital logic circuitry, analog circuitry, discrete circuitry, a combination of gates, or any other type of hardware or combination thereof. Alternatively or additionally, each logical component can include memory hardware, such as a portion of memory, that contains instructions executable by a processor or other processor to implement one or more functions of the logical component. When any one logical component includes a portion of memory that contains instructions executable by a processor, that logical component can or can not include the processor. In some embodiments, each logical component can be only a portion of memory or other physical memory that contains instructions executable by a processor or other processor to implement the functions of the respective logical component, and the logical component itself can not include any other hardware. Because each logical component includes at least some hardware, even if that hardware includes software, each logical component can be referred to interchangeably as a hardware logical component.

[0195] A second action can be said to be a "response to" a first action, whether the second action is directly or indirectly caused by the first action. A second action can occur substantially later in time than the first action and still be a response to the first action. Similarly, a second action can be said to be a response to a first action even if intervening actions occur between the first and second actions, and even if one or more of the intervening actions directly cause the second action to be performed. For example, if a first action sets a flag, and a third action initiates the second action if the flag is set, the second action can be a response to the first action.

[0196] To clarify usage and put the public on notice, the phrases "at least one of A, B,... and N" or "at least one of A, B,... N, or combinations thereof" or "A, B,... and / or N" are defined in the broadest sense, to encompass one or more elements from the listed items A, B,... and N, unless explicitly stated otherwise. In other words, these phrases mean any combination of one or more of the listed items A, B,... or N, including any single one of A, B,... or N, or combinations thereof, along with any of the items not listed.
