In a number of aspects, the processor 410, the transmitter circuit 420, and the memory 430 can be included in a single device, while in other aspects, it can be included in different devices, such as components of a decentralized architecture. As described in more detail, for one or more UEs joining multiple beam transmissions, system 400 can assist in scheduling downlink assignments and/or uplink grants.

One or more Downlink Control Information (DCI) messages may be generated for a user equipment processor 410. DCI may each post of the multi-beam (e.g., beam comprising a N _b, where N _b is in integer greater than 1) transmitting a separate transmission beam associated with the UE, each with one or more such transmit beams A different transmit beam is associated, through which the eNB of system 400 communicates with the UE. Where the N _b transmit beams are each derived from a single TP (eg, a TP of the eNB), the multiple beam transmit is a TP intra-transmit, and the processor 410 can generate N _b DCI messages, N _b transmit The beams each have a message. On the other hand, if at least two of the N _b transmit beams originate from separate TPs, then the multiple beam transmissions are inter-TP transmissions, and processor 410 can generate less than N _b DCI messages.

The processor 410 can assign each of the DCI messages to a search space associated with the DCI message of one or more search spaces. In a number of aspects, one or more search spaces may include a single common search space, and each of the DCI messages may be assigned to a single common search space. In this aspect, each of the DCI messages can include a beam indicator indicating which of the transmit beams the DCI is associated with.

The various characteristics of the DCI message generated by processor 410 may vary depending on the embodiment.

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 that indicates one of the HARQ processes (eg, N) associated with the separate transmit beams associated with the DCI message. In various such aspects, the indicated HARQ process can be identified based on the combination of the indicated HARQ process IDs and which transmit beam the DCI message is associated with.

In the second set of embodiments, the corresponding HARQ process may directly indicate the HARQ process ID of the DCI message, indicating one of the HARQ processes of the larger shared number of HARQ processes. For example, the total number of HARQ processes may be N _b xN, where N is the number of processes for single beam operation and may be indicated by N _b xM bits, where M is used to indicate a single beam operation HARQ processes the number of bits in the ID.

The second set of embodiments facilitates forwarding through xPDSCH from different beams originally transmitted, which can provide diverse gains. For example, in a number of aspects, one of the DCI messages generated by processor 410 may be a DCI message associated with the forwarding of the primary transmission previously transmitted by a different transmit beam associated with the DCI message. Where forwarding occurs, forwarding the associated DCI may include a HARQ process switching indicator that may indicate HARQ processing associated with the forwarding.

Referring to FIG. 5, a block diagram of a system 500 for receiving and receiving uplink control messages associated with multiple beam transmissions received at a user equipment (UE) is illustrated in accordance with various aspects described herein. Figure. System 500 can include a receiver circuit 510, a processor 520 (eg, 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 can include a variety of Any of the storage media, and can 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, system 500 can be embodied within a user equipment (UE). As will be described in detail later, system 500 can assist in receiving and replying to one or more downlink control channel messages from one or more search spaces associated with multiple beam transmissions.

The receiver circuit 510 TP available from one or more (e.g., a single TP TP within a scene, and for more than one TP TP between scenes) N _b received in a multi-beam transmission on the transmit beam, and can provide a multiplicity of The beam is transmitted to the processor 520.

The processor 520 may receive from the receiver circuit 510 emitting multiple beams, and may be from one or more search reply N _b separate spaces DCI messages, each line associated with a separate number N _b transmit beam emitted beam. Depending on the embodiment, the DCI message may be replied from a common search space or from N _b consecutive search spaces, and in different embodiments, the content of the DCI message may vary.

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. The 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 a number of aspects, one or more UCI messages may be a single UCI message containing feedback information associated with N _b transmit beams. In the other face, such a message can be UCI or more of a N _b UCI messages, each line associated with a separate number N _b transmit beam emitted beam.

Moreover, depending on the embodiment, the TP or TPs of the UCI message output for subsequent transmission may vary. In some embodiments, where each UCI includes feedback information associated with a single transmit beam (or one or more transmit beams from a common TP), each UCI message can be output for subsequent transmission to TP from which the transmit beam or the transmit beams are received. In other embodiments, each of the one or more UCI messages can be output for subsequent transmission to a single TP. The single TP may be the TP that the primary beam of the N _b beams is received, or may be the TP as indicated by the configuration received through higher layer signaling (eg, RRC, etc.).

In order to provide specific examples of the techniques discussed herein, the specific embodiments and techniques are discussed later in the context of dual beam transmission. However, these embodiments should be aware of techniques may be expanded and extended to other numbers of transmit beams (e.g., N _b> 2).

Dual beam (or N _b - beam) mode of operation, UE may assume required from two (or N _b) transmit (Tx) beam received downlink signal. The Tx beam from the serving TP may be referred to as the primary Tx beam, and the Tx beam from the (one or more) auxiliary TP may be referred to as the secondary Tx beam.

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

In various aspects, the addition or removal of the secondary Tx beam can be transmitted through higher layer signaling indications, such as through MAC control elements, RRC signaling, and the like. The higher layer signaling may indicate that the transmit beam is increased or removed by the BRS index of the transmit beam, which 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 face-to-face, a DCI message can be used to carry information about a beam. Thus, in dual beam mode, the UE may assume two DCI can be used to frame a subframe is detected (and the beam mode to N _b, N _b is used to detect a DCI).

In the face of a first set, when decoding a 5G physical downlink control channel (xPDCCH), the UE may have additional search space for each of the secondary transmit beams. Search Space main and secondary emission beam emitted beam may be continuous, wherein the means for two CCE index (or all N _b) of the search space may be continuous. In this aspect, given the maximum search space size in all possible aggregation levels, the starting CCE index for the (primary) secondary transmit beam may be the consecutive CCE after the last CCE in the primary transmit beam (and For embodiments with _Nb > 2, the starting CCE for each additional secondary transmit beam can similarly follow the previous secondary transmit beam).

As an example of the scope of this set, if the search space is defined by clause 9.1.1 of the Third Generation Partnership Project (3GPP) Technical Specification (TS) 36.213, the possible aggregation level there may 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 Indicating a first CCE index in the search space for the primary transmit beam (and similarly for the next secondary transmit beam, replacing ε ₁ with ε ₂ where ε ₂ indicates a search for the secondary transmit beam The first CCE index in space, etc.). Referring to Figure 6, a schematic diagram of various configuration examples for a search space for a dual beam mode of operation in accordance with the description herein is illustrated.

In several embodiments, xPDSCH transmissions on individual beams may have independent HARQ operations. In these embodiments, the UE receiving the multiple beam transmission may find the corresponding HARQ process and the transmit beam of the DCI based on the HARQ process ID indicated by the DCI. The transmit beam of the DCI can be obtained by its search space location in the embodiment, wherein the DCI for the separate transmit beams is in separate search spaces and can be determined from the DCI when explicitly indicated by the DCI.

Referring to Figure 7, an illustration of one example of HARQ processing indications for independent HARQ operations in various dual-beam scenarios is illustrated in accordance with the description herein. In the DCI in the main search space in FIG. 7, the HARQ process ID may be x, and in the DCI in the secondary search space, the HARQ process ID may be y. The total number of HARQ processes for one beam can be N.

In other embodiments, the corresponding HARQ process may be indicated by the HARQ process ID in the DCI. In several such embodiments, the total number of HARQ processes may be amplified for UEs having multiple beam transmissions. In one example, in the dual beam embodiment, the total number of HARQ processes may be 2N (or N _b xN in the N _b beam multiple beam embodiment), and the number of bits of the HARQ process ID may 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 facilitates xPDSCH forwarding on beams that are different from the original beam.

In several aspects, any of the transmit beams can be employed to forward the xPDSCH previously transmitted on another transmit beam to obtain a diversified gain. For example, in a dual beam embodiment, a primary transmit beam can be applied to forward an xPDSCH that is initially transmitted through a secondary transmit beam, or vice versa.
