The system 400 may include a processor 410 (for example, a baseband processor, such as one of the baseband processors discussed in connection with FIG. 1), a transmitter circuit 420, and a memory 430 (which may include any of a variety of storage media) One, and may store instructions and/or data associated with one or more of the processor 410 or the transmitter circuit 420). In various aspects, the system 400 can be included in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (Evolved Node-B, eNodeB, or eNB) or other base stations in a wireless communication network. In several aspects, the processor 410, the transmitter circuit 420, and the memory 430 may be included in a single device, while in other aspects, they may be included in different devices, such as components of a distributed architecture. As will be described in detail later, for one or more UEs connecting multiple beam transmissions, the system 400 can assist in scheduling downlink assignments and/or uplink grants.

The processor 410 can generate one or more downlink control information (DCI) messages for a user equipment. Each of the DCI messages can be associated with _{a separate transmit beam that is transmitted to the UE by multiple beams (for example, including N b} beams, where N _b is an integer greater than 1), such as those each with one or more transmit beams. A different transmit beam is associated, and the eNB of the system 400 is used to communicate with the UE through this beam. In the case where the N _b transmit beams each originate from a single TP (for example, a TP of the eNB), the multiple beam transmission is intra-TP transmission, and the processor 410 can generate N _b DCI messages and N _b transmissions Each beam has a message. On the other hand, if _{at least two of the N b} transmission beams originate from separate TPs, the multiple beam transmission is an inter-TP transmission, and the processor 410 can generate less than N _b DCI messages.

The processor 410 may assign each of the DCI messages to a search space associated with the DCI message of one or more search spaces. Among several aspects, one or more search spaces can include a single common search space, and each of the DCI messages can be assigned to a single common search space. Among these aspects, each of the DCI messages may include a beam indicator, which indicates which transmit beam the DCI is associated with. In the case of a common search space, in some aspects, DCI messages can be allocated to separate control channel elements (CCE), while in other aspects, part or all of the DCI messages can be allocated to it and other DCI messages One or more shared CCE indexes to be shared.

In other aspects, one or more search spaces may include N _b search spaces. In various embodiments, the search spaces may be continuous (for example, so that the start of a search space of the next beam can be transmitted from the previous CCE). The search space of the beam is determined, etc.). In these aspects, each of the N _b search spaces can be associated with one of the N _b transmit beams separately from the transmit beam, and the processor 410 can assign each DCI message to the transmit beam associated with the DCI message.

Depending on the embodiment, the various characteristics of the DCI message generated by the processor 410 may be different.

Embodiment of the first set of embodiments, N _b of each of the transmit beams may independently and automatically repeats the process for HARQ operations associated with the request (HARQ) and mixed separately. In these embodiments, each DCI message may include a HARQ process, which indicates one HARQ process in the total number of HARQ processes (for example, N) associated with the separate transmit beams associated with the DCI message. In various of these aspects, based on the combination of the indicated HARQ process ID and which transmit beam the DCI message is associated with, the indicated HARQ process can be identified.

In the second set of embodiments, the corresponding HARQ process can be separately indicated by the HARQ process ID of the DCI message to indicate one HARQ process among the HARQ processes with a larger shared number. For example, the total number of HARQ processing can be N _b xN, where N is the number of processing for single-beam operation, and can be _{indicated by N b} xM bits, where M is used to indicate the number of single-beam operations The number of bits of the HARQ processing ID.

In the case where forwarding occurs, the DCI associated with the forwarding may include a HARQ process swap indicator, which may indicate the HARQ process associated with the forwarding.

Referring to FIG. 5, there is illustrated a block diagram of a system 500 for assisting the reception of downlink control messages and the generation of uplink control messages associated with multiple beam transmissions received by a user equipment (UE) as described herein. picture. The system 500 may include a receiver circuit 510, a processor 520 (for example, a baseband processor, such as one of the baseband processors discussed in connection with FIG. 1), a transmitter circuit 530, and a memory 540 (which may include a variety of Any of the storage media may store instructions and/or data associated with one or more of the receiver circuit 510, the processor 520, or the transmitter circuit 530). In various aspects, the system 500 can be contained within a user equipment (UE). As will be described in detail later, the system 500 can assist in the reception and response of one or more downlink control channel messages from one or more search spaces associated with multiple beam transmission.

_{The receiver circuit 510 can receive multiple beam transmissions on N b} transmit beams from one or more TPs (for example, a single TP is used for intra-TP scenarios, and more than one TP is used for inter-TP scenarios), and can provide multiple The beam is transmitted to the processor 520.

The processor 520 may receive multiple beam transmissions from the receiver circuit 510, and may reply N _b separate DCI messages from one or more search spaces, each of which is associated with a separate transmit beam of the _{N b transmit beams.} Depending on the embodiment, the DCI message can be returned from a common search space, or from N _b consecutive search spaces, and the content of the DCI message can be different in different embodiments.

The processor 520 can also generate one or more uplink control information (UCI) messages, and output the one or more UCI messages for subsequent transmission to at least one of the TPs. One or more UCI messages may include _{some or all of the following information associated with N b} transmit beams: beam reference signal received power (BRS-RP), channel status information (CSI), HARQ-acknowledgement (HARQ-ACK) )Wait.

In several aspects, one or more UCI messages can be a single UCI message containing feedback information associated _{with N b transmit beams.} In other aspects, the one or more UCI messages may be N _b UCI messages, each of which is associated with a separate transmission beam of the _{N b transmission beams.}

In addition, depending on the embodiment, the TP or TPs of the UCI message output for subsequent transmission can be different. In some embodiments, where each UCI includes feedback information associated with a single transmit beam (or with one or more transmit beams from a common TP), each UCI message can be output for subsequent transmission to TP, from where the transmit beam or the transmit beams are received. In other embodiments, each of one or more UCI messages may be output for subsequent transmission to a single TP. The single TP may be a TP where _{the main beam of the N b} beams is received, or may be a TP received through higher layer signaling (for example, RRC, etc.) as indicated by the configuration.

In order to provide specific examples of the techniques discussed herein, specific embodiments and techniques are discussed in the context of dual-beam transmission. However, it should be understood that these embodiments and techniques can be extended to other numbers of transmit beams (for example, N _b > 2).

In the dual-beam (or N _b -beam) operation mode, the UE may assume that it needs to _{receive downlink signals from two (or N b} ) transmit (Tx) beams. The Tx beam from the serving TP may be referred to as the primary Tx beam, and the Tx beam from the auxiliary TP(s) may be referred to as the secondary Tx beam.

For multi-beam operation in TP, the primary Tx beam can be the Tx beam with the strongest BRS-RP measured from one or more antenna panels of the UE, and the secondary Tx beam can be the strongest BRS measured from another antenna panel -The Tx beam of the RP, or the second strongest among one or more antenna panels when the main Tx beam is the strongest among all antenna panels.

In various aspects, the addition or removal of secondary Tx beams can be signaled through higher layers, such as MAC control components, RRC signalling, and so on. The higher layer signaling may indicate that the transmit beam can pass through the BRS index of the beam to be added or removed, and the index may be explicitly indicated by the UE with the BRS-RP for the secondary transmit beam.

For downlink (DL) control signaling, DCI can be used to carry downlink assignments and/or uplink grants. In the orientation, a DCI message can be used to carry the information of a beam. Therefore, in the dual beam mode, the UE can assume that two DCIs can be used to be detected in one subframe (and in the N _b beam mode, N _b DCIs can be used to be detected).

In the aspect of a first set, when decoding the 5G physical downlink control channel (xPDCCH), the UE may have additional search space for each of the secondary transmit beams. The search spaces of the primary transmission beam and the secondary transmission beam may be continuous, and _{the CCE indexes for the two (or all N b} ) search spaces may be continuous. In these aspects, given the maximum search space size in all possible aggregation levels, the starting CCE index for the (primary) secondary transmit beam can be the subsequent CCE (and) after the last CCE in the primary transmit beam. For embodiments with N _b > 2, the starting CCE for each additional secondary transmit beam can similarly follow the previous secondary transmit beam).

As an example of the orientation of this set, if the search space is as defined in Clause 9.1.1 of the Third Generation Partnership Project (3GPP) Technical Specification (TS) 36.213, the possible aggregation level at this point can be {1,2, 4,8} and its corresponding search space size can be {6,12,8,16}CCE, then the search space for the secondary transmit beam can start from _{the CCE with index ε 1} +17, where ε ₁ Indicate the first CCE index in the search space for the primary transmit beam (and in a similar manner for the next secondary transmit beam, replace ε _{1 with ε 2} , where ε ₂ indicates the search for the secondary transmit beam The first CCE index in the space, etc.). Referring to FIG. 6, there is illustrated a schematic diagram according to one of the various configuration examples described herein for the search space for the dual-beam mode of operation.

In some embodiments, the xPDSCH transmission on each beam may have independent HARQ operation. In these embodiments, the UE receiving the multiple beam transmission can find the corresponding HARQ process and the transmission beam of the DCI based on the HARQ process ID indicated by the DCI. The transmission beam of the DCI can be obtained from its search space position in the embodiment, wherein the DCI for the separate transmission beam is in the separate search space, and can be determined from the DCI when explicitly indicated by the DCI.

Referring to FIG. 7, there is illustrated a schematic diagram according to an example of various HARQ processing instructions for independent HARQ operation in a dual-beam scenario described herein. In the DCI in the primary search space in FIG. 7, the HARQ process ID can be x, and in the DCI in the secondary search space, the HARQ process ID can be y. The total number of HARQ processing for one beam can be N.

In other embodiments, the corresponding HARQ process can be indicated by the HARQ process ID in the DCI alone. In several of these embodiments, the total number of HARQ processing can be amplified for UEs with multiple beam transmissions. In one example, in the dual beam embodiment, the total number of HARQ processing can be 2N (or _{N b xN in the N b} beam multiple beam embodiment), and the number of HARQ processing ID bits can be 2M, where M is the number of bits used for the HARQ process ID for a single beam operation. Comparing N HARQ processes per beam, this is helpful for xPDSCH forwarding on a beam different from the original beam.
