[0020] This disclosure describes a method and apparatus for generating and transmitting scheduling requests (SRs) under user equipment (UE) aggregated transmission.
[0021] Next-generation (NG) mobile communication systems are propelling the world towards an increasingly interconnected and networked society. High-speed, low-latency wireless communication relies on efficient network resource management and allocation between user equipment and radio access network nodes (including but not limited to radio base stations). NG networks promise to provide high-speed, low-latency, and ultra-reliable communication capabilities, meeting the needs of various industries and users.
[0022] In some wireless communication schemes, such as when the UE is located at the cell edge of a base station, UE aggregation transmission can be used to improve the throughput or reliability of transmissions from the UE. However, there are many issues / controversies associated with the operation of UE aggregation transmission. For example, at least one issue / controversy may relate to how to generate and / or transmit scheduling requests (SRs) under UE aggregation transmission.
[0023] This disclosure describes various embodiments of generating and transmitting scheduling requests (SRs) under UE aggregation transmission, which solve at least one of the problems / controversies discussed above, thereby improving the performance of wireless communication, and in particular achieving efficient generation and / or transmission of SRs under UE aggregation transmission, and / or improving the throughput and / or reliability of UE transmissions.
[0024] In some implementations, UE aggregation transmission can be divided into multiple modes, such as transparent transmission mode and non-transparent transmission mode. In transparent transmission mode, the base station may not know the group of UEs paired for UE aggregation transmission (e.g., first UE (UE 1) and second UE (UE 2)). In non-transparent transmission mode, the base station knows that the group of UEs is paired for UE aggregation transmission and knows that data from one UE can be transmitted by another UE; for example, the base station may know that data from UE 1 can be transmitted by UE 2.
[0025] In some implementations, the pass-through mode can have drawbacks that can lead to inefficiencies. For a non-limiting example, the channel environments (such as channel state information (CSI), interference, etc.) of UE 1 and UE 2 may differ. The base station may not be aware that UE 1 and UE 2 are paired for UE aggregation transmission; therefore, the base station may always configure parameter values in the uplink (UL) grant of UE 1 based on UE 1's channel environment. UE 1's data is ultimately transmitted by UE 2 based on UE 2's channel environment. Clearly, in this case, when UE 1's data is transmitted by UE 2, parameters not matching UE 2's channel environment are not used, which can lead to inefficiencies.
[0026] Figure 1 A wireless communication system 100 is illustrated, comprising a wireless network node 118 (also referred to as a network base station 118) and one or more user equipment (UE) devices 110. The wireless network node may include a network base station, which may be a nodeB (NB, e.g., gNB) in a mobile telecommunications context. Each UE may wirelessly communicate with the wireless network node via one or more radio channels 115 for downlink / uplink communication. For example, a first UE 110 may wirelessly communicate with the wireless network node 118 via a channel including multiple radio channels during a specific time period. The network base station 118 may send higher-layer signaling to the UE 110. This higher-layer signaling may include configuration information for communication between the UE and the base station. In one embodiment, the higher-layer signaling may include radio resource control (RRC) messages.

In this case, UE 1 and UE 2 can represent different role types: UE 1 can have the role type of an anchor UE, while UE 2 can have the role type of an auxiliary UE. In some implementations, UE 1's data may include UE 1's uplink control information (UCI), such as hybrid automatic repeat request acknowledgment (HARQ-ACK), scheduling request (SR), channel state information (CSI), etc.

[0067] Specifically, one method may include the following: When UE 1 and / or UE 2 have a scheduling requirement, UE 1 or UE 2 forms SR information based on predefined rules, determines the corresponding SR sequence (e.g., marked as m) based on the configured sequence (e.g., marked as m) and the state of the formed SR information, and transmits the determined sequence in the SR resources that share SR resources.
[0068] In some implementations, after the base station receives and parses the determined sequence, one of the following three situations can be obtained: 1) UE 1 has no scheduling requirement, but UE 2 has a scheduling requirement; 2) UE 1 has a scheduling requirement, but UE 2 has no scheduling requirement; or 3) Both UE 1 and UE 2 have scheduling requirements.
[0069] In some implementations, when the base station does not receive a defined sequence, the base station may assume that neither UE 1 nor UE 2 has a scheduling requirement, meaning that neither UE 1 nor UE 2 needs to be scheduled. Correspondingly, when neither UE 1 nor UE 2 has a scheduling requirement, UE 1 and UE 2 do not transmit the defined sequence in the SR resources.
[0070] In some implementations, SR information for no more than two UEs can be formed based on one of the following predefined rules. In some implementations, each paired UE corresponds to 1 bit, where "0" indicates that the UE has no scheduling requirement and "1" indicates that the UE has a scheduling requirement. In some implementations, the reverse is also true, i.e., "1" indicates that the UE has no scheduling requirement and "0" indicates that the UE has a scheduling requirement.
[0071] In some implementations, the SR information bits of the paired UEs can be concatenated based on the role of the paired UE or based on the C-RNTI of the paired UEs. For example, the SR information bits corresponding to the anchor UE can be placed before (or after) the SR information bits corresponding to the auxiliary UE. Another example is that the SR information bits corresponding to the anchor UE and the auxiliary UE can be concatenated in ascending (or descending) order according to the C-RNTI of the paired UEs.
[0072] For a non-limiting example, when SR information is formed based on the ascending order of the C-RNTIs of paired UEs, and when the C-RNTI of UE 1 is less than the C-RNTI of UE 2, the formed SR information includes at least one of the following three cases: '01' indicates that UE 1 does not have a scheduling requirement, but UE 2 does; '10' indicates that UE 1 has a scheduling requirement, but UE 2 does not; and / or '11' indicates that UE 1 has a scheduling requirement, and UE 2 also has a scheduling requirement.
[0073] In some implementations, the SR sequence may be determined according to at least one of the following rules.
[0074] In some implementations, the base station and the UE agree that each of the three scenarios above corresponds to an SR sequence. That is, at least three SR sequences need to be determined to correspond to the three scenarios. Alternatively, the base station can configure an initial sequence index (m_0) for the paired UE via signaling, and the UE determines the corresponding sequence cyclic shift (m_cs) based on the formed SR information according to Table 1. UE 1 and / or UE 2 determine the final SR sequence (e.g., labeled m) of the formed SR information based on the initial sequence index (m_0) and the sequence cyclic shift (m_cs) (for a non-limiting example, based on and , i.e., m = m_0 + m_cs). UE 1 and / or UE 2 transmit the final SR sequence in the SR resources.
[0075] For a non-restrictive example, when there are 12 sequences and the indices are between 0 and 11 (inclusive), the range of m_0 is between 0 and 3 (inclusive). “3” is obtained by dividing the total number of sequences by the total number of states of the paired UE’s SR information.
[0076] In some implementations, the base station receives the final SR sequence in the SR resources. The base station can obtain the formed SR information based on the final SR sequence index and the configured m_0, according to Table 1. The base station, for example, parses the formed SR information based on the ascending order of the C-RNTI of the paired UEs. The base station determines the scheduling requirements of UE 1 and / or UE 2.
[0077] Table 1: The generated SR information and m cs Mapping relationship between
[0078] In some implementations, the base station can configure at least three SR sequences for the above three situations via signaling.
[0079] In Table 1, the index interval of the SR sequences corresponding to the SR information formed in different locations is at least 4, which allows us to obtain the maximum Euclidean distance for a total of 12 sequences. This reduces mutual interference.
[0080] In some implementations, when using 12 sequences (with indices ranging from 0 to 11), four sequence groups can be determined based on Table 1, and the four sequence groups are configured with different m_0, namely {0, 4, 8}, {1, 5, 9}, {2, 6, 10} and {3, 7, 11}.
[0081] In some implementations, when four paired UEs need to transmit their respective SR sequences, for example, UE1 and UE2 are paired for UE aggregation transmission, UE3 and UE4 are paired for UE aggregation transmission, UE5 and UE6 are paired for UE aggregation transmission, and UE7 and UE8 are paired for UE aggregation transmission. To save SR resources, the base station can configure the four paired UEs to use the same SR resource, and can configure different m_0 for each of the four paired UEs. For example, m_0=0 for UE1 and UE2, m_0=1 for UE3 and UE4, m_0=2 for UE5 and UE6, and m_0=3 for UE7 and UE8. Thus, based on Table 1, the sequence group used by UE1 and UE2 is {0, 4, 8}, the sequence group used by UE3 and UE4 is {1, 5, 9}, the sequence group used by UE5 and UE6 is {2, 6, 10}, and the sequence group used by UE7 and UE8 is {3, 7, 11}.
[0082] In some implementations, the base station and the UE can predefine which sequence group to use as the paired UE, or the base station can notify the UE via signaling which sequence group to use as the paired UE.
[0083] In some implementations, SR sequences are transmitted in SR resources based on PUCCH format 0.
[0084] In some implementations, UE 1 and UE 2 need to exchange their SR information.
[0085] In some implementations, SR sequences can be transmitted simultaneously.
[0086] Alternatively, UE 1 and UE 2 can transmit the same defined SR sequence simultaneously within the same SR resource.
[0087] In some implementations, UE1 and UE2 exchange their SR information. UE1 and UE2 each form SR information based on the scheduling requirements of the paired UEs and predefined rules. UE1 and UE2 determine the final SR sequence using Table 1 based on the configured m_0 and the formed SR information. UE1 and UE2 simultaneously transmit the final SR sequence in the SR resources. The base station receives and parses the final SR sequence, obtaining one of the three scenarios described above.
[0088] This transmission method may improve the reliability of SR transmission. For example, paired UEs located at the edge of a cell could consider using this transmission method to improve the reliability of SR transmission.
[0089] In some implementations, after UE 1 (or UE 2) determines the final SR sequence based on the above method, UE 1 (or UE 2) can notify UE 2 (or UE 1) of the final SR sequence, and UE 1 and UE 2 simultaneously transmit the final SR sequence in the SR resource.
[0090] In some implementations, the base station can configure the transmission mode of SR sequences within the same SR resource via signaling. For example, the base station can configure the final SR sequence to be transmitted simultaneously by UE 1 and UE 2, or the base station can configure the final SR sequence to be transmitted by either UE 1 or UE 2. Alternatively, if the base station and the UE agree to execute one of the aforementioned transmission modes by default, the base station can configure another transmission mode via signaling to replace the default transmission mode.
[0091] In some implementations, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the edge of a cell, the paired UEs can request UE 1 and UE 2 to transmit the final SR sequence simultaneously. Alternatively, when UE 1 has low remaining battery power, the paired UEs can request only UE 2 to transmit the final SR sequence. The base station configures corresponding transmission modes for UE 1 and UE 2 based on the request information.
[0092] In some implementations, the SR information of paired UEs is transmitted based on PUCCH format 0. Here, different states of the SR information of paired UEs can correspond to different SR sequences. The base station can obtain the state of the SR information of paired UEs from the received SR sequence through reverse operation.
[0093] In some implementations, for more than two UEs in a UE aggregation, the SR information of these UEs is also connected based on their C-RNTI ascending or descending order. The connected SR information is modulated to obtain modulated SR information. The modulated SR information is transmitted in the SR resources based on PUCCH format 2, PUCCH format 3, or PUCCH format 4.
[0094] In some implementations, the modulated SR information can be transmitted by a pair of paired UEs, or by multiple paired UEs simultaneously within the same SR resource.
[0095] Example Set II In some embodiments, paired UE 1 and UE 2 are configured to share an SR configuration and the corresponding SR resources. UE 1 and / or UE 2 determine an SR sequence and transmit the SR sequence in the configured SR resources, the SR sequence being modulated by the SR information of UE 1 and / or UE 2. The SR sequence may indicate that UE 1 and / or UE 2 has a scheduling requirement.
[0096] In some implementations, when UE 1 and / or UE 2 have scheduling requirements, UE 1 or UE 2 can form SR information based on predefined rules, modulate the formed SR information to obtain modulated SR information, modulate the modulated SR information into a configured sequence (marked as n0) to obtain a modulated sequence, and transmit the modulated sequence in the SR resources that share SR resources.
[0097] In some implementations, after the base station receives and parses the modulated sequence, one of the following three scenarios can be obtained: 1) UE 1 has no scheduling requirement, but UE 2 has a scheduling requirement; 2) UE 1 has a scheduling requirement, but UE 2 has no scheduling requirement; and / or 3) both UE 1 and UE 2 have scheduling requirements.
[0098] In some implementations, when the base station does not receive a modulated sequence, the base station assumes that the requirement is that neither UE 1 nor UE 2 has been scheduled, meaning that neither UE 1 nor UE 2 needs to be scheduled. Correspondingly, when neither UE 1 nor UE 2 has a scheduling requirement, UE 1 and UE 2 do not transmit modulated sequences in SR resources.
[0099] In some implementations, SR information for no more than two UEs can be formed based on predefined rules, which may include one of the following rules: Each paired UE corresponds to 1 bit, where "0" indicates that the UE has no scheduling requirement, and "1" indicates that the UE has a scheduling requirement; and vice versa. The SR information bits of the paired UEs are concatenated based on the role of the paired UEs or based on the C-RNTI of the paired UEs. For example, the SR information bits corresponding to the anchor UE are placed before (or after) the SR information bits corresponding to the auxiliary UE.
[0100] In some implementations, the SR information bits corresponding to the anchor UE and the auxiliary UE are concatenated in ascending (or descending) order based on the C-RNTI of the paired UE.
[0101] For a non-limiting example, when SR information is formed based on the ascending order of the C-RNTIs of paired UEs, and when the C-RNTI of UE 1 is less than the C-RNTI of UE 2, the formed SR information includes at least one of the following three cases: '01' indicates that UE 1 has no scheduling requirement, but UE 2 has a scheduling requirement; '10' indicates that UE 1 has a scheduling requirement, but UE 2 has no scheduling requirement; and / or '11' indicates that UE 1 has a scheduling requirement, and UE 2 also has a scheduling requirement.
[0102] In some implementations, the generated SR information is modulated using QPSK to obtain modulated SR information. The modulated SR information is then modulated into a configured (or predefined) sequence to obtain a modulated SR sequence. The modulated SR sequence is transmitted within shared SR resources.
[0103] In some implementations, the base station and the UE can agree on an SR sequence, and the modulated SR information can be modulated into the SR sequence. Alternatively, the base station can configure the SR sequence (denoted as n0, where n0 is the sequence index, ranging from n00 to n11) via signaling, and modulate the modulated SR information into the SR sequence.
[0104] In some implementations, SR sequences are transmitted in SR resources based on PUCCH format 1. UE 1 and UE 2 need to exchange their SR information.
[0105] In some implementations, each SR sequence can be transmitted simultaneously. In some implementations, UE 1 and UE 2 can simultaneously transmit the same modulated SR sequence within the same SR resource.
[0106] In a non-limiting example, UE 1 and UE 2 exchange their SR information, and UE 1 and UE 2 each determine the modulated SR sequence based on the method described above. Then, UE 1 and UE 2 simultaneously transmit the modulated SR sequence in the SR resources. The base station receives and parses the modulated SR sequence and obtains one of the three cases described above.
[0107] This transmission method is beneficial for improving the reliability of SR transmission. For example, paired UEs located at the edge of a cell can consider using this transmission method.
[0108] Alternatively, after UE 1 (or UE 2) determines the modulated SR sequence based on the above method, UE 1 (or UE 2) notifies UE 2 (or UE 1) of the modulated SR sequence, and then UE 1 and UE 2 simultaneously transmit the modulated SR sequence in the SR resource.
[0109] In some implementations, the base station can configure the transmission mode of SR sequences in the same SR resource via signaling. For example, the base station can configure the final SR sequence to be transmitted simultaneously by UE 1 and UE 2, or the base station can configure the final SR sequence to be transmitted by either UE 1 or UE 2.
[0110] In some implementations, the base station and the UE agree to execute one of the aforementioned transmission modes by default. The base station can configure another transmission mode through signaling to replace the default transmission mode.
[0111] In some implementations, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the edge of a cell, the paired UEs can request UE 1 and UE 2 to transmit modulated SR sequences simultaneously. Alternatively, when UE 1 has low remaining battery power, the paired UEs can request only UE 2 to transmit modulated SR sequences. The base station configures corresponding transmission modes for UE 1 and UE 2 based on the request information.
[0112] In some implementations, the SR information of paired UEs is ultimately transmitted based on PUCCH format 1. Here, the SR information of paired UEs is modulated in the same SR sequence, and the base station can obtain the state of the SR information of paired UEs from the received SR sequence through reverse operation.
[0113] In some implementations, for more than two UEs in a UE aggregation, the SR information of these UEs is also connected based on their C-RNTI ascending or descending order. The connected SR information is modulated to obtain modulated SR information. The modulated SR information is transmitted in SR resources sharing SR resources based on PUCCH format 2, PUCCH format 3, or PUCCH format 4.
[0114] In some implementations, the modulated SR information can be transmitted by one of the paired UEs, or by multiple paired UEs simultaneously within the same SR resource.
[0115] Example Set III In some embodiments, paired UE 1 and UE 2 are configured to share an SR configuration and the corresponding SR resources. When UE 1 and / or UE 2 have scheduling needs, UE 1 and / or UE 2 transmit their respective configured (SR) sequences in the same or different SR resources sharing the SR resources. The SR sequences may indicate that UE 1 and / or UE 2 have scheduling needs.
[0116] In some implementations, when UE 1 and / or UE 2 have scheduling requirements, UE 1 and / or UE 2 respectively transmit their respective configured sequences (denoted as u0) in the same or different SR resources sharing SR resources.
[0117] In some implementations, after the base station receives and parses the configured sequence, one of the following situations can be obtained: 1) UE 1 has a scheduling requirement; and / or 2) UE 2 has a scheduling requirement.
[0118] In some implementations, when the base station does not receive the configured sequence, the base station considers that neither UE 1 nor UE 2 needs to be scheduled, i.e., neither UE 1 nor UE 2 needs to be scheduled. Correspondingly, when neither UE 1 nor UE 2 has a scheduling requirement, UE 1 and UE 2 do not transmit the configured sequence in the SR resources.
[0119] In some implementations, SR sequences can be configured in the following way: Different sequences (u0) can be configured as their respective SR sequences for paired UE 1 and UE 2. When UE 1 (or UE 2) has a scheduling requirement, UE 1 (or UE 2) transmits the corresponding configured SR sequence in the SR resources that share SR resources.
[0120] In some implementations, when both UE 1 and UE 2 have scheduling requirements, UE 1 and UE 2 transmit their respective configured SR sequences in the same or different SR resources that share SR resources.
[0121] In some implementations, to determine the scheduling needs of UE 1 and UE 2, the base station always needs to parse the received SR sequences of UE 1 and UE 2 separately. When neither UE 1 nor UE 2 has a scheduling need, UE 1 and UE 2 do not transmit the corresponding SR sequences in the SR resources.
[0122] In some implementations, UE 1 and UE 2 do not need to exchange SR information with each other.
[0123] In some implementations, the configured SR sequence can be transmitted in the following ways.
[0124] In some implementations, when UE 1 has a scheduling requirement, the configured SR sequence of UE 1 can be transmitted by UE 2 in the SR resources sharing the SR resources. In this case, the base station receives the SR sequence of UE 1 from the SR resources, and the base station considers UE 1 to have a scheduling requirement. This helps UE 1 save power.
[0125] In some implementations, when UE 2 has a scheduling requirement, the configured SR sequence of UE 2 can be transmitted by UE 1 in the SR resources sharing the SR resources. In this case, the base station receives the SR sequence of UE 2 from the SR resources, and the base station considers UE 2 to have a scheduling requirement. This helps UE 2 save power.
[0126] In some implementations, when UE 1 has a scheduling requirement, the configured SR sequence of UE 1 can be transmitted simultaneously by UE 1 and UE 2 in the same SR resource that shares the SR resource. In this case, the base station receives the SR sequence of UE 1 from the SR resource, and the base station considers UE 1 to have a scheduling requirement. In this case, this is beneficial to improve the reliability and coverage of the SR sequence of UE 1.
[0127] In some implementations, when UE 2 has a scheduling requirement, the configured SR sequence of UE 2 can be transmitted simultaneously by UE 1 and UE 2 in the same SR resource that shares the SR resource. In this case, the base station receives the SR sequence of UE 2 from the SR resource, and the base station considers UE 2 to have a scheduling requirement. In this case, this is beneficial to improve the reliability and coverage of the SR sequence of UE 2.
[0128] In some implementations, the base station can configure the transmission mode of the SR sequence of UE 1 (or UE 2) within the same SR resource via signaling. For example, the base station can configure the SR sequence of UE 1 (or UE 2) to be transmitted simultaneously by UE 1 and UE 2, or the base station can configure the SR sequence of UE 1 (or UE 2) to be transmitted by either UE 1 or UE 2. Alternatively, the base station and the UE agree to execute one of the aforementioned transmission modes by default, and the base station can configure another transmission mode to replace the default transmission mode via signaling.
[0129] Alternatively, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the edge of a cell, the paired UEs can request UE 1 and UE 2 to simultaneously transmit UE 1's (or UE 2's) SR sequence. For example, when UE 1 (or UE 2) has low remaining battery power, the paired UEs can request only UE 2 (or UE 1) to transmit UE 1's (or UE 2's) SR sequence 0. The base station configures the corresponding transmission mode for UE 1 and UE 2 based on the request information.
[0130] In some implementations, the SR information of UE 1 (or UE 2) is transmitted based on PUCCH format 0. Here, the states of the SR information of UE 1 and UE 2 correspond to their respective configured SR sequences. The base station can obtain the states of the SR information of UE 1 and / or UE 2 from the received SR sequences through reverse operation.
[0131] In some implementations, for more than two UEs in a UE aggregation, different SR sequences are configured for each of these UEs. UEs with scheduling requirements can directly transmit the corresponding SR sequence in the same SR resource based on PUCCH format 0.
[0132] Example Set IV In some embodiments, paired UE 1 and UE 2 are configured to share an SR configuration and the corresponding SR resources. When UE 1 and / or UE 2 have a scheduling requirement, UE 1 and / or UE 2 respectively transmit their configured (SR) sequences on the same or different SR resources sharing the SR resources. The transmitted (SR) sequences are modulated by the SR information of UE 1 and / or UE 2. The SR sequences can indicate that UE 1 and / or UE 2 have a scheduling requirement.
[0133] In some implementations, when UE 1 and / or UE 2 have a scheduling request, UE 1 and / or UE 2 respectively modulate their respective SR information into a configured (SR) sequence (denoted as w0), and transmit the modulated sequence in the same or different SR resources sharing SR resources respectively.
[0134] In some implementations, the base station receives and parses the modulated sequence to obtain one of the following: 1) UE 1 has a scheduling requirement; and / or 2) UE 2 has a scheduling requirement.
[0135] In some implementations, when the base station does not receive a modulated sequence, the base station considers that neither UE 1 nor UE 2 needs to be scheduled, i.e., neither UE 1 nor UE 2 needs to be scheduled. Correspondingly, when neither UE 1 nor UE 2 has a scheduling requirement, UE 1 and UE 2 do not transmit modulated sequences in SR resources.
[0136] In some implementations, the SR sequence can be configured in the following ways.
[0137] In some implementations, different sequences (w0) are configured as their respective SR sequences for paired UE 1 and UE 2. When UE 1 (or UE 2) has a scheduling requirement, UE 1 (or UE 2) transmits the corresponding configured SR sequence in the SR resources that share SR resources.
[0138] In some implementations, when both UE 1 and UE 2 have scheduling requirements, UE 1 and UE 2 transmit their respective configured SR sequences in the same or different SR resources that share SR resources.
[0139] In some implementations, to determine the scheduling needs of UE 1 and UE 2, the base station always needs to parse the received SR sequences of UE 1 and UE 2 respectively. When neither UE 1 nor UE 2 has a scheduling need, then UE 1 and UE 2 do not transmit the corresponding SR sequences in the SR resources.
[0140] In some implementations, UE 1 and UE 2 do not need to exchange SR information with each other.
[0141] In some implementations, the modulated SR sequence can be transmitted in the following manner.
[0142] In some implementations, when UE 1 has a scheduling requirement, the modulated SR sequence of UE 1 can be transmitted by UE 2 in the shared SR resources. In this case, the base station receives the SR sequence of UE 1 from the SR resources, and the base station considers UE 1 to have a scheduling requirement. This helps UE 1 save power.
[0143] In some implementations, when UE 2 has a scheduling requirement, the modulated SR sequence of UE 2 can be transmitted by UE 1 in the SR resources sharing the SR resources. In this case, the base station receives the SR sequence of UE 2 from the SR resources, and the base station considers UE 2 to have a scheduling requirement. This helps UE 2 save power.
[0144] In some implementations, when UE 1 has a scheduling requirement, the modulated SR sequence of UE 1 can be transmitted simultaneously by UE 1 and UE 2 in the same SR resource that shares the SR resource. In this case, the base station receives the SR sequence of UE 1 from the SR resource, and the base station considers UE 1 to have a scheduling requirement. In this case, this is beneficial to improve the reliability and coverage of the SR sequence of UE 1.
[0145] In some implementations, when UE 2 has a scheduling requirement, the modulated SR sequence of UE 2 can be transmitted simultaneously by UE 1 and UE 2 in the same SR resource that shares the SR resource. In this case, the base station receives the SR sequence of UE 2 from the SR resource, and the base station considers UE 2 to have a scheduling requirement. In this case, this is beneficial to improve the reliability and coverage of the SR sequence of UE 2.
[0146] In some implementations, the base station can configure the transmission mode of the modulated SR sequence of UE 1 (or UE 2) in the same SR resource via signaling. For example, the base station can configure UE 1 and UE 2 to transmit the modulated SR sequence of UE 1 (or UE 2) simultaneously, or the base station can configure UE 1 or UE 2 to transmit the modulated SR sequence of UE 1 (or UE 2). Alternatively, if the base station and UE agree to execute one of the aforementioned transmission modes by default, the base station can configure another transmission mode to replace the default transmission mode via signaling.
[0147] In some implementations, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the edge of a cell, the paired UEs can request UE 1 and UE 2 to simultaneously transmit the modulated SR sequence of UE 1 (or UE 2). For example, when the remaining battery power of UE 1 (or UE 2) is low, the paired UEs can request only UE 2 (or UE 1) to transmit the modulated SR sequence of UE 1 (or UE 2). The base station configures the corresponding transmission mode for UE 1 and UE 2 based on the request information.
[0148] In some implementations, the SR information of UE 1 (or UE 2) is transmitted based on PUCCH format 1. Here, the SR information states of UE 1 and UE 2 are modulated into their respective configured SR sequences. The base station can obtain the SR information states of UE 1 and / or UE 2 from the modulated SR sequences through reverse operation.
[0149] In some implementations, when there are more than two paired UEs, different SR sequences are configured for each of these UEs. UEs with scheduling requirements can modulate SR information into their respective configured SR sequences and transmit the modulated SR sequences in the same SR resource based on PUCCH format 1.
[0150] For paired UEs, various implementation methods in Implementation Set I and Implementation Set III can be supported independently, or various implementation methods in Implementation Set I and Implementation Set III can be effectively combined for paired UEs. For example, when only one of the paired UEs needs to transmit the SR sequence, the method in Implementation Set III can be executed. For example, when the paired UEs need to transmit the SR sequence simultaneously, the method in Implementation Set I can be executed.
[0151] For paired UEs, various implementation methods in Implementation Set II and Implementation Set IV can be supported independently, or various implementation methods in Implementation Set II and Implementation Set IV can be effectively combined for paired UEs. For example, when only one of the paired UEs needs to transmit the SR sequence, the method in Implementation Set IV can be executed. For example, when the paired UEs need to transmit the SR sequence simultaneously, the method in Implementation Set II can be executed.
[0152] Implementation Example Set V In various embodiments, paired UE 1 and UE 2 are configured to share an SR configuration and share SR resources corresponding to the SR configuration. When UE 1 has a scheduling requirement, UE 1 and / or UE 2 transmit a shared (SR) sequence in the shared SR resources. The shared SR sequence can indicate that UE 1 has a scheduling requirement.
[0153] In some implementations, when UE 1 has a scheduling requirement, UE 1 and / or UE 2 transmit a shared sequence (denoted as s0) in the shared SR resources.
[0154] In some implementations, after the base station receives and parses the shared sequence, one of the following situations can be obtained: 1) UE 1 has a scheduling requirement.
[0155] In some implementations, when the base station does not receive a shared sequence, it considers UE 1 not to be scheduled. Correspondingly, when UE 1 has no scheduling requirement, UE 1 and / or UE 2 do not transmit the shared sequence in the shared SR resources.
[0156] In some implementations, the shared SR sequence can be configured in the following ways.
[0157] In some implementations, a sequence (s0) is configured for paired UE 1 and UE 2 as the SR sequence for UE 1 (e.g., the anchor UE). The configured sequence may be referred to as a shared sequence. When UE 1 has a scheduling requirement, UE 1 and / or UE 2 transmit the shared SR sequence in shared SR resources.
[0158] In some implementations, UE 1 and UE 2 need to exchange their SR information.
[0159] In some implementations, the configured SR sequence can be transmitted in the following ways.
[0160] In some implementations, when UE 1 has a scheduling requirement, UE 1's shared SR sequence can be transmitted by UE 2 within the shared SR resources. In this case, the base station receives UE 1's shared SR sequence from the SR resources, and the base station considers UE 1 to have a scheduling requirement. This helps UE 1 save power.
[0161] In some implementations, when UE 1 has a scheduling requirement, the shared SR sequence of UE 1 can be transmitted simultaneously by UE 1 and UE 2 within the same SR resource sharing the SR resource. In this case, the base station receives the SR sequence of UE 1 from the SR resource, and the base station considers UE 1 to have a scheduling requirement. In this case, this is beneficial for improving the reliability and coverage of the SR sequence of UE 1.
[0162] In some implementations, the base station can configure the transmission mode of UE1's shared SR sequence within the same SR resource via signaling. For example, the base station can configure UE1 and UE2 to transmit UE1's shared SR sequence simultaneously, or the base station can configure UE1 or UE2 to transmit UE1's shared SR sequence. Alternatively, if the base station and UE agree to default to one of the aforementioned transmission modes, the base station can configure another transmission mode via signaling to replace the default transmission mode.
[0163] In some implementations, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the cell edge of intrusion, the paired UEs can request UE 1 and UE 2 to simultaneously transmit the shared SR sequence of UE 1. For example, when the remaining battery power of UE 1 (or UE 2) is low, the paired UEs can request only UE 2 (or UE 1) to transmit the shared SR sequence of UE 1. The base station configures the corresponding transmission mode for UE 1 and UE 2 based on the request information.
[0164] In some implementations, the shared SR information of UE1 is transmitted based on PUCCH format 0. Here, the state of UE1's SR information corresponds to the shared SR sequence. The base station can obtain the state of UE1's SR information from the received SR sequence through reverse operation.
[0165] Implementation Examples Collection VI In some embodiments, paired UE 1 and UE 2 are configured to share an SR configuration and share SR resources corresponding to the SR configuration. When UE 1 has a scheduling requirement, UE 1 and / or UE 2 transmit a shared (SR) sequence in the shared SR resources. The transmitted (SR) sequence is modulated by the SR information of UE 1. The shared SR sequence can indicate that UE 1 has a scheduling requirement.
[0166] In some implementations, when UE 1 has a scheduling requirement, UE 1 and / or UE 2 respectively modulate UE 1's SR information into a shared (SR) sequence (denoted as e0) and transmit the shared sequence (denoted as e0) in the shared SR resources.
[0167] In some implementations, after the base station receives and parses the shared sequence, one of the following situations may be obtained: 1) UE 1 has a scheduling requirement.
[0168] In some implementations, when the base station does not receive a shared sequence, it considers UE 1 not to be scheduled. Correspondingly, when UE 1 does not have a scheduling requirement, UE 1 and / or UE 2 do not transmit the shared sequence in the shared SR resources.
[0169] In some implementations, the shared SR sequence can be configured in the following ways.
[0170] In some implementations, a configuration sequence (e0) is set for paired UE 1 and UE 2 as the SR sequence for UE 1 (the anchor UE). The configured sequence may be referred to as a shared sequence. When UE 1 has a scheduling requirement, UE 1 and / or UE 2 modulate the shared SR sequence and transmit it in the shared SR resources.
[0171] In some implementations, UE 1 and UE 2 need to exchange their SR information.
[0172] In some implementations, the configured SR sequence can be transmitted in the following ways.
[0173] In some implementations, when UE 1 has a scheduling requirement, UE 1's shared SR sequence can be transmitted by UE 2 within the shared SR resources. In this case, the base station receives UE 1's shared SR sequence from the SR resources, and the base station considers UE 1 to have a scheduling requirement. This helps UE 1 save power.
[0174] In some implementations, when UE 1 has a scheduling requirement, the shared SR sequence of UE 1 can be transmitted simultaneously by UE 1 and UE 2 within the same SR resource sharing the SR resource. In this case, the base station receives the SR sequence of UE 1 from the SR resource, and the base station considers UE 1 to have a scheduling requirement. This improves the reliability and coverage of the SR sequence of UE 1.
[0175] In some implementations, the base station can configure the transmission mode of UE1's shared SR sequence within the same SR resource via signaling. For example, the base station can configure UE1 and UE2 to transmit UE1's shared SR sequence simultaneously, or the base station can configure UE1 or UE2 to transmit UE1's shared SR sequence. Alternatively, if the base station and UE agree to default to one of the aforementioned transmission modes, the base station can configure another transmission mode via signaling to replace the default transmission mode.
[0176] In some implementations, UE 1 or UE 2 can send signaling to the base station to request a specific transmission mode. For example, when paired UEs are located at the edge of a cell, the paired UEs can request UE 1 and UE 2 to simultaneously transmit the shared SR sequence of UE 1. Alternatively, when the remaining battery power of UE 1 (or UE 2) is low, the paired UEs can request only UE 2 (or UE 1) to transmit the shared SR sequence of UE 1. The base station configures the corresponding transmission mode for UE 1 and UE 2 based on the request information.
[0177] In some implementations, the shared SR information of UE1 is transmitted based on PUCCH format 1. Here, the state of UE1's SR information is modulated into a shared SR sequence. The base station can obtain the state of UE1's SR information from the received SR sequence through the reverse operation.
[0178] Implementation Examples VII Various embodiments describe the determination of a shared SR resource, which may be applicable to embodiment sets I through VI. In some implementations, the shared SR resource is configured to include one of the following.
[0179] In some implementations, UE 1 is configured with one or more sets of SR resources based on SR configuration information, while UE 2 is configured to share the SR resources configured by UE 1. The base station and UE agree that UE 2 will use the SR resources configured by UE 1 by default. Alternatively, the base station commands UE 2 to use the SR resources configured by UE 1 via signaling. Alternatively, the base station can configure UE 2 to have the same SR resources as UE 1 via signaling. Alternatively, new RRC signaling is introduced, and this new RRC signaling is used to configure one or more common sets of SR resources for UE 1 and UE 2.
[0180] In some implementations, UE 2 is configured with one or more SR resource sets based on SR configuration information, while UE 1 is configured to share the SR resources configured by UE 2. The base station and UE agree that UE 1 will use the SR resources configured by UE 2 by default. Alternatively, the base station commands UE 1 to use the SR resources configured by UE 2 via signaling. Alternatively, the base station can configure UE 1 to have the same SR resources as UE 2 via signaling. Alternatively, a new RRC signaling is introduced, which is used to configure one or more common SR resource sets for UE 1 and UE 2.
[0181] Various embodiments describe the implicit identification of anchor UEs and auxiliary UEs. In some implementations, the base station and the UE agree in advance that the anchor UE or auxiliary UE is determined from the paired UEs based on SR sequences or SR requests transmitted in configured shared SR resources.
[0182] In some implementations, this method applies to paired UEs acting as each other's anchor UE and auxiliary UE. Alternatively, paired UEs are always assumed to be each other's anchor UE and auxiliary UE, and the anchor UE and auxiliary UE are determined based on the transmission and reception of corresponding SR requests.
[0183] In a non-limiting example, UE 1 and UE 2 are paired for UE aggregation transmission and configured to share SR resources. When UE 1 sends a scheduling request in the shared SR resources, the base station, upon receiving the scheduling request, considers UE 1 as the anchor UE and UE 2 as the auxiliary UE, and UE 2 transmits UE 1's data. When UE 2 sends a scheduling request in the shared SR resources, the base station, upon receiving the scheduling request, considers UE 2 as the anchor UE and UE 1 as the auxiliary UE, and UE 1 transmits UE 2's data. Thus, paired UEs do not need to report pairing information. For paired UEs, the UE can indirectly inform the base station about its role among paired UEs by transmitting scheduling requests in the configured shared SR resources.
[0184] Various embodiments describe transmission methods for different uplink (UL) channels of aggregated UEs. In some implementations, UE 1 and UE 2 are paired for UE aggregation transmission, with UE 2 transmitting data from UE 1 (including uplink control information, UCI). UCI may include at least one of the following: HARQ-ACK, SR, and / or CSI. The method may be described using the following cases and / or options.
[0185] For Case 1 ("Case 1"): In slot n, UE 1 wants to transmit PUCCH1 (used to carry UCI) and PUSCH1 of UE 1, and PUCCH1 and PUSCH1 overlap in the time domain.
[0186] In some implementations, the solution may include multiplexing the UCI in PUCCH1 into PUSCH1, having UE 1 transmit PUSCH1, and not having UE 1 transmit PUCCH1 (canceling PUCCH1). This method helps reduce the complexity of UE 1's transmission; for example, UE 1 only transmits one uplink channel instead of transmitting two uplink channels simultaneously.
[0187] In some implementations, PUCCH1 and PUSCH1 have the same priority.
[0188] In some implementations, for situation 1 above, based on UE aggregation transmission, one of the following options (solutions) can be used.
[0189] Option 1: UE 1's PUSCH1 is transmitted by UE 2, and UE 1's PUCCH1 is transmitted by UE 1. In this way, UE 1 still only transmits one uplink channel.
[0190] Option 2: UE 1's PUCCH1 is transmitted by UE 2, and UE 1's PUSCH1 is transmitted by UE 1. In this way, UE 1 still only transmits one uplink channel.
[0191] Option 3: The UCI in PUCCH1 of UE 1 is multiplexed in PUSCH1, but the result of the multiplexing, PUSCH1, is transmitted by UE 2. This method can be used to save power for UE 1.
[0192] Option 4: The UCI in UE 1's PUCCH1 is multiplexed in PUSCH1, and the resulting PUSCH1 is transmitted simultaneously by UE 1 and UE 2. This method is suitable for improving transmission reliability when UE 1 and UE 2 are located at the cell edge.
[0193] In Case 1, the base station and the UE agree to use one of the above methods; alternatively, the base station may configure the UE to use one of the above methods.
[0194] In Case 1, the base station can receive PUCCH1 or PUSCH1 from UE 1 and / or UE 2, and perform the inverse operation to obtain the UCI in PUSCH1 and PUCCH1. The processing on the base station side will not be described in detail.
[0195] Here, PUCCH1 may also include the SRS (Sounding Reference Signal) signal of UE 1.
[0196] For Case 2 ("Case 2"): In slot n, UE 1 wants its PUCCH1 (used to carry UCI) to be transmitted by UE 1, and UE 1 also wants its PUSCH1 to be transmitted by UE 1. PUCCH1 and PUSCH1 overlap in the time domain. PUCCH1 and PUSCH1 have different priorities.
[0197] In some implementations, for Case 2 above, one solution may include the following: When UE 1 does not configure signaling to multiplex PUCCH and PUSCH of different priorities, then between the two channels PUCCH1 and PUSCH1, the channel with higher priority is transmitted by UE 1, and the channel with lower priority is not transmitted by UE 1 (it is canceled by UE 1). This approach helps reduce the complexity of UE transmission; for example, UE 1 only transmits one uplink channel instead of transmitting two uplink channels simultaneously.
[0198] For Case 2 above, based on UE aggregation transmission, one of the following methods can be used.
[0199] Option 5: UE 1's PUSCH1 is transmitted by UE 2, and UE 1's PUCCH1 is transmitted by UE 1. In this way, UE 1 still only transmits one uplink channel.
[0200] Option 6: UE 1's PUCCH1 is transmitted by UE 2, and UE 1's PUSCH1 is transmitted by UE 1. In this way, UE 1 still only transmits one uplink channel.
[0201] Option 7: Between the two channels PUCCH1 and PUSCH1, the channel with higher priority is transmitted by UE 2, and the channel with lower priority is transmitted by UE 1. In this way, UE 1 still only transmits one uplink channel.
[0202] Option 8: Between the two channels PUCCH1 and PUSCH1, the channel with higher priority is transmitted by UE 1, and the channel with lower priority is transmitted by UE 2. In this way, UE 1 still only transmits one uplink channel.
[0203] In Case 2, the base station and the UE agree to use one of the above methods; alternatively, the base station may configure the UE to use one of the above methods.
[0204] In some implementations, in Case 2, the base station may receive PUCCH1 or PUSCH1 from UE 1 and / or UE 2 and perform the inverse operation to obtain the UCI in PUSCH1 and PUCCH1. The base station may perform actions as described in this disclosure.
[0205] In some implementations, PUCCH1 may include the SRS signal of UE 1.
