[0046] In order to facilitate understanding, some related technical knowledge related to the embodiments of the present application is introduced first. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional schemes, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0047] Beam management
[0048] With the development of communication technology, the application range of aritifical intelligence (AI) / machine learning (ML) technology in communication scenarios is increasingly expanding. For example, the 3GPP Release-18 (Rel-18) has begun to study the application of AI / ML technology in the NR air interface (also known as air interface), and formed a research report TR38.843. The report defines three typical use cases, including: channel state information (CSI) feedback enhancement, beam management (BM) and positioning accuracy enhancement.
[0049] To promote the application of AI / ML techniques, 3GPP officially started the standardization work of AI / ML techniques for NR air interface in Rel-19 through the proposal RP-240774. Exemplarily, the standardization work of beam management includes prediction for downlink transmit beam (DL Tx beam). Exemplarily, the training and prediction of AI / ML model can be located at the UE / terminal device side, i.e., UE-side model. Exemplarily, the training and prediction of AI / ML model can be located at the network (NW) side, i.e., NW-side model.
[0050] As an example, beam management mainly includes two sub-use cases: spatial-domain beam management and temporal-domain beam management. Spatial-domain beam management, i.e., BM-Case1, mainly performs spatial-domain downlink beam prediction for Set A of beams based on the measurement results of Set B of beams. Temporal-domain beam management, i.e., BM-Case2, mainly performs temporal downlink beam prediction for Set A of beams based on the historical measurement results of Set B of beams.
[0051] As an example, Set B is a set of beams, the measurement results of which are used as the input of AI / ML model. Set A is also a set of beams, and the output of AI / ML model is the prediction for Set A. The beams in Set A and Set B can be in the same frequency range.
[0052] As an example, the related report (e.g., TR 38.843) makes the following recommendations for the application of AI / ML in BM-Case2.
[0053] Recommendation 1: Set A and Set B need to consider the application of three relationships. Relationship 1 is that Set A and Set B are different, and Set B is not a subset of Set A. Relationship 2 is that Set A and Set B are different, and Set B is a subset of Set A. Relationship 3 is that Set A and Set B are the same.
[0054] Proposal 2: As the input of the AI / ML model, K (K≥1) latest measurement instances need to consider the following multiple choices. Choice 1 is to determine the model input based only on Set B layer 1 reference signal received power (L1-RSRP) measurement. Choice 2 is to determine the model input based on Set B L1-RSRP measurement and auxiliary information. Choice 3 is to determine the model input based on Set B L1-RSRP measurement and corresponding downlink transmission beam and / or reception beam identity (ID). It can be seen that the input of the AI / ML model must include the Set B L1-RSRP measurement result.
[0055] Proposal 3: Based on the output of the AI / ML model, F predictions for F future time instances (also referred to as time instances) can be obtained. Each prediction corresponds to a time instance, and F is greater than or equal to 1.
[0056] Optionally, the temporal beam prediction process can include two stages: an observation phase and a prediction phase. The observation phase can also be referred to as an observation window or an observation period. The prediction phase can also be referred to as a prediction window or a prediction period.
[0057] To facilitate understanding, the temporal beam prediction method in the BM-Case2 scenario is exemplarily described below in combination with FIG. 2 and FIG. 3. It should be understood that the embodiments of the present application are only discussed taking the BM-Case2 scenario as an example. In other words, the technical solutions in the embodiments of the present application are not limited to the BM-Case2 scenario, but can also be applied to the BM-Case1 scenario.
[0058] FIG. 2 is a flowchart of a method of temporal beam prediction by L1-RSRP according to an embodiment of the present application. FIG. 3 is a schematic diagram of temporal beam prediction based on AI / ML. The method shown in FIG. 2 can be used to predict future transmission and reception beams at the base station side (gNB / BS) and / or the user side. The beam prediction model (for example, AI / ML model) in FIG. 2 and FIG. 3 can be implemented at the base station side, or the user side, or both the base station and the user side.
[0059] Referring to FIG. 2, at step S210, the base station 201 performs beam sweeping to the terminal device 202. The beam can be a CSI beam or a synchronization signal block (SSB) beam. The SSB can also be used to represent a synchronization signal and physical broadcast channel block (SS / PBCH block). In step S210, the base station 201 can perform full / partial CSI / SSB beam sweeping.
[0060] At step S220, the terminal device 202 sends RSRP feedback to the base station 201.
[0061] At step S230, steps S210 and S220 are repeated for T1 time intervals.
[0062] At step S240, a beam prediction function is performed.
[0063] At step S250, the base station 201 transmits to the terminal device 202 with predicted beams and repeats in a prediction window.
[0064] Steps S210 to S230 in FIG. 2 belong to an observation phase, in which the base station 201 can receive T1 RSRP vectors. Steps S240 and S250 belong to a prediction phase. For example, the base station 201 in this phase can predict T2 best beams. The base station 201 and the terminal device 202 can repeat the observation and prediction window.
[0065] FIG. 3 is a schematic diagram of time-domain beam prediction based on an AI / ML model. FIG. 3 takes time axis as the horizontal axis. For the device where the AI / ML model is located, the observation window can collect a plurality of measurement values related to the beam set of Set B as input values of the AI / ML model. The AI / ML model can output a plurality of predicted values within the prediction window for the beam set of Set A. The plurality of predicted values can be used to determine the best beam indexes.
[0066] As shown in FIG. 3, T1 measurement values, x <0> , x <1> , …, x <t1-1>< / t1-1> , can be collected within the observation window. The T1 measurement values as input of the AI / ML model can output T2 predicted values within the prediction window, respectively Based on the T2 predicted values, the best beam indexes can be obtained.
[0067] As can be seen from FIG. 2 and FIG. 3, in the observation phase, T1 measurement results (such as L1-RSRP) measured by the beam set of Set B within the observation window are collected and input to the AI / ML model. In the prediction phase, the AI / ML model can generate T2 predicted results (such as L1-RSRP) within the prediction window for the beam set of Set A. These predicted results are used to infer the best beam or the best set of beams.
[0068] It should be noted that when the AI / ML model is located at the terminal device side (UE side), the terminal device can directly input the collected measurement results to the AI / ML model for prediction, without having to report a large number of measurement results, thereby saving resource overhead. However, the inference results of the UE side model still need to be reported to the network or base station. The reporting content of the model inference results has reached a preliminary consensus.
[0069] Exemplarily, according to the consensus reached at 3GPP RAN1#116 and RAN#116bis: in the spatial domain beam management (BM-Case1) scenario, the reporting content of the inference results of the UE side AI / ML model includes the following options.
[0070] Option one: the reporting content includes beam information of the top K (K≥1) strong beams in Set A.
[0071] Option 2: The reporting content includes beam information and RSRP of Top-K beams in Set A.
[0072] Further study Option 3: The reporting content includes beam information and probability information of Top-K beams in Set A.
[0073] Further study Option 4: The reporting content includes beam information, RSRP and confidence information of RSRP of Top-K beams in Set A.
[0074] Wherein, the predicted RSRP of Top-K beams can be the predicted RSRP output by the AI / ML, or is the measured L1-RSRP.
[0075] Exemplarily, according to the consensus reached at the 3GPP RAN1#116bis meeting: in the time-domain beam management (BM-Case2) scenario, the reporting content based on the inference result of the UE-side AI / ML model supports multiple implementation modes. For example, it is supported to include the inference result for N (N≥1) future time instances in one inference result report. For another example, the inference result information on each time instance is an inference report in the spatial-domain beam management (BM-Case1), that is, the inference result information on each time instance at least includes the beam information of Top-K beams. For another example, the RSRP of the predicted beam in the inference result report is the predicted RSRP output by the UE-side AI / ML model.
[0076] From the above, the terminal device can predict the inference result on multiple time instances and report. The inference result information on each time instance at least includes the beam information of K strong beams (Top-K beams). In multiple time instances, the K strong beams on different time instances can be different.
[0077] For ease of understanding, one possible prediction result of time-domain beam prediction is exemplarily described below in combination with FIG. 4. FIG. 4 shows N time instances for M beams. The M beams are beam #1, beam #2, …, beam #M, and the N time instances are time instance #1, time instance #2, …, time instance #N. In the prediction window, the prediction result of each time instance includes a predicted beam in the M beams. The beams in the M beams other than the predicted beam belong to the beams in the beam set A.
[0078] Referring to FIG. 4, it is assumed that Top-K beams will be predicted on each of the N time instances. ibeams, where i = 1, …, N. The Top-K1 beams in time instance #1 in FIG. 4 include beams #1 to #3, and the Top-K2 beams in time instance #2 do not include beam #1, and the Top-K N beams do not include beam #1. It can be seen that the predicted beams in time instance #1 are different from the predicted beams in time instance #2 and time instance #N.
[0079] In this scenario, how the terminal device reports the inference result becomes a technical problem to be considered. For example, in the scenario of predicting time-domain downlink beams based on a UE-side AI / ML model, how to effectively report the multiple strong beam information on multiple time instances needs to be considered.
[0080] For example, when the Top-K i beams on at least two time instances are different, how to report the different Top-K i beams, and how to establish a corresponding relationship between the N time instances and the N Top-K i beams in the inference result report are problems to be solved urgently.
[0081] In addition, in the scenario of predicting time-domain downlink beams based on a UE-side AI / ML model, how to effectively report the multiple strong beam information and corresponding RSRP information on multiple time instances needs to be considered.
[0082] For example, if the output of the UE-side AI / ML model has a corresponding RSRP prediction value for each beam on the N time instances, how to effectively report these RSRP prediction values and how to establish a corresponding relationship with the N Top-K i beams also need to be considered.
[0083] To solve the above problems, an embodiment of the present application provides a method and device in a node for wireless communication. The first node (for example, a UE) in the method can measure a first resource set located on a first type of time instance according to a first configuration signaling. After the first node predicts according to the measurement result, the first node can send N second type of time instances and multiple second type of beam information through first information. It can be seen that the first information indicates multiple time instances and corresponding multiple beam information, so that the multiple strong beam information and / or corresponding RSRP information on multiple time instances can be effectively reported, signaling overhead is reduced, and resource utilization efficiency is improved.
[0084] It should be understood that the reporting method of the prediction result based on the UE-side AI / ML model mentioned above is not only applicable to the scenario of time domain beam management, but also applicable to the scenario of space domain beam management. In addition, although the present application mainly discusses the UE-side model, the scheme in the present application is not limited to the UE-side model, but can also be used for the NW-side model, or can also be used for the UE-side and NW-side double-side model.
[0085] It should be noted that the beam mentioned in the embodiments of the present application can include or replace at least one of the following: physical beam, logical beam, spatial filter, spatial parameter, spatial domain filter, spatial domain transmission filter, spatial domain reception filter, and antenna port.
[0086] The method embodiment of the present application will be described in detail below in combination with the drawings. FIG. 5 is a flowchart of a method in a first node for wireless communication according to an embodiment of the present application. As shown in FIG. 5, the method is performed by the first node.

[0090] As an embodiment, the first node can be deployed with an AI / ML model to perform time domain beam prediction or space domain beam prediction. When the AI / ML model is a UE-side model, the first node can be a UE; when the AI / ML model is a network-side model, the first node can be a base station.
[0091] The method shown in FIG. 5 includes steps S510 to S530, which will be described below.
[0092] At step S510, the first node receives the first configuration signaling. The first node can receive the first configuration signaling in various manners. In some embodiments, the first node can receive the first configuration signaling configured by a higher layer. For example, the first node can determine the first configuration signaling based on the configuration information of the higher layer. In some embodiments, the first node can directly receive the first configuration signaling sent by the second node.

[0095] As an embodiment, the second node can be another terminal device which performs sidelink communication with the first node.
[0096] In some embodiments, the first node can determine the manner of receiving the first configuration signaling based on pre-configuration or dynamic configuration.
[0097] The first configuration signaling is used to indicate a first resource set. Any resource in the first resource set can be a time domain resource, a frequency domain resource, or a space domain resource, or a combination of multiple resources, which is not limited herein.
[0098] In some embodiments, part or all of the resources in the first resource set are used for signal transmission. The signal transmitted by the first resource set can be an uplink signal, a downlink signal, or a sidelink signal.
[0099] As an embodiment, the first resource set comprises multiple resources, and the multiple resources are used to transmit a downlink signal. For example, the multiple resources in the first resource set are used for the network device to send a downlink signal to the terminal device. As a sub-embodiment of the above embodiment, the downlink signal comprises at least one of a synchronization signal / physical broadcast channel block (SSB), a channel state information-reference signal (CSI-RS), and a demodulation reference signal (DMRS).

[0223] Referring to FIG. 7, steps S710 to S740 are the same as steps S610 to S640 in FIG. 6, and will not be described again. Different from FIG. 6, the multiple first type of beams in FIG. 7 are wide beams, and the multiple second type of beams are narrow beams. That is, when the multiple first type of beams are beams in Set B and the multiple second type of beams are beams in Set A, Set B is different from Set A.
[0224] As can be known from FIG. 6 and FIG. 7, when the first node predicts the multiple second type of beams based on the measurement result of the multiple first type of beams, the multiple second type of beams can be the same as the multiple first type of beams or different from the multiple second type of beams.
[0225] In some embodiments, the plurality of second-type beam information corresponds to N second-type time instances. Exemplarily, the N second-type time instances respectively correspond to N beam information sets, and the plurality of second-type beam information is beam information in the N beam information sets. The N beam information sets can also be referred to as N groups of beam information.
[0226] As an embodiment, the N beam information sets respectively correspond to the N second-type time instances one by one. The N second-type time instances correspond to the plurality of second-type beam information through the N beam information sets. For example, one or more second-type beam information in the beam information set X corresponds to the second-type time instance X corresponding to the beam information set X.
[0227] As an embodiment, the N beam information sets include the plurality of second-type beam information. As an embodiment, the N beam information sets are respectively the plurality of second-type beam information. As an embodiment, any second-type beam information in the plurality of second-type beam information is one beam information in the N beam information sets.
[0228] As an embodiment, the plurality of second-type beam information corresponding to the N second-type time instances includes one second-type beam information in each beam information set. The one second-type beam information is the information of one beam with the strongest signal quality in each beam information set.
[0229] As an embodiment, the plurality of second-type beam information corresponding to the N second-type time instances includes a plurality of second-type beam information in each beam information set. The plurality of second-type beam information is the information of a plurality of beams with the strongest signal quality in each beam information set.
[0230] As an embodiment, the plurality of second-type beam information corresponding to the N second-type time instances includes one or more second-type beam information in each beam information set. The one or more second-type beam information is the information of one or more beams with a signal quality greater than a specific threshold in each beam information set.
[0231] In some embodiments, the N second-type time instances include a first time instance, and the first beam information set is one beam information set in the N beam information sets corresponding to the first time instance. The first time instance corresponds to L beams. The first beam information set includes beam information of one or more strongest beams in the L beams at the first time instance, and L is greater than 1.
[0232] As an embodiment, the first time instance is any second-type time instance in the N second-type time instances.
[0233] As an embodiment, the L beams are all beams in a beam set A.
[0234] As an embodiment, the L beams are part of the beam set A.
[0235] As an embodiment, any of the L beams is one of the beam set A.
[0236] As an embodiment, the multiple second-type beams are beams in the L beams.
[0237] As an embodiment, the multiple second-type beams are part of the L beams.
[0238] As an embodiment, any of the multiple second-type beams is one of the L beams.
[0239] As an embodiment, the L beams are all or part of the beams employed at the first time instance.
[0240] As an embodiment, the value of L in the L beams can be equal to the value of M shown in FIG. 4.
[0241] As an embodiment, the first time instance corresponding to the L beams means that the resource corresponding to the first time instance can be used to send part or all of the L beams.
[0242] As an embodiment, the first time instance is any one of the N second-type time instances. That is, each of the N second-type time instances can correspond to the L beams.
[0243] As an embodiment, the one or more strongest beams indicated by the first beam information set are one or more beams with the strongest signal quality in the L beams. As an embodiment, the one or more strongest beams indicated by the first beam information set are one or more beams with the largest RSRP value in the L beams. As an embodiment, the one or more strongest beams indicated by the first beam information set are one or more beams with the largest L1-RSRP value in the L beams.
[0244] As an embodiment, the signal quality includes the RSRP value. As an embodiment, the signal quality includes the L1-RSRP value. As an embodiment, the signal quality includes the L3-RSRP value.
[0245] In some embodiments, the one or more strongest beams are K beams with the strongest signal quality among the L beams at the first time instance, where K is greater than or equal to 1. Illustratively, each of the N second-type time instances corresponds to the K beams with the strongest signal quality, respectively. When K = 1, only the strongest beam is reported for each time instance.
[0246] As an example, the K beams with the strongest signal quality are reported for each time instance when K is a given value. For example, only the beam information corresponding to the K RSRPs with the strongest signal quality predicted for each time instance is reported when K is a given value.
[0247] As an example, the number of beams with the strongest signal quality reported for each time instance is no more than K when K is a maximum value.
[0248] In some embodiments, the one or more strongest beams are beams with a signal quality greater than a first threshold among the K beams with the strongest signal quality among the L beams at the first time instance. In this scenario, K is a maximum value. For example, only the beam information corresponding to the RSRP(s) greater than the first threshold among the K RSRPs with the strongest signal quality predicted for each time instance is reported.
[0249] In some embodiments, the one or more strongest beams are K beams with a signal quality greater than a first threshold among the L beams at the first time instance. When the first threshold is a fixed value, K is a dynamic parameter. For example, K is 1 when only 1 beam among the L beams has a signal quality greater than the first threshold. For another example, K is 3 when 3 beams among the L beams have a signal quality greater than the first threshold.
[0250] As an example, the first threshold is pre-configured, pre-defined, or configured by the network or higher layer signaling.
[0251] As an example, the first threshold can be dynamically configured. For example, when the strongest beams are K beams with a signal quality greater than the first threshold among the L beams, the first threshold can be lowered if there is no beam among the L beams with a signal quality greater than the first threshold.
[0252] As an example, K is fixed or configured.
[0253] In some embodiments, the number of one or more strongest beams corresponding to different time instances can or can not be equal. For example, when the i-th second-type time instance among the N second-type time instances corresponds to K i beams, K i may or can not be equal.
[0254] As an example, the i-th beam information set in the N beam information sets may include K beams from the L beams in the i-th second-type time instance among the N second-type time instances. i Beam information of the strongest beam, 1≤i≤N, K i ≥1. At least two of the N beam information sets are different, or, at least two of the N beam information sets correspond to K. i The values are different.
[0255] As an example, at least two of the N beam information sets correspond to K. i The strongest beams are different.
[0256] As an example, the K i The strongest beam is the K beam with the strongest signal quality among the L beams in the i-th time instance of the N second-type time instances. i One beam.
[0257] As an example, the K i The strongest beam is the K beam with the strongest signal quality among the L beams in the i-th time instance of the N second-type time instances. i The beam whose signal quality is greater than the first threshold among the beams.
[0258] As an example, the K i The strongest beam is the one whose signal quality is greater than the first threshold among the L beams in the i-th type of time instance out of the N type of time instances. i One beam.
[0259] As an example, if K on different time instances i Equal, i.e., K i If K = K, then the resources or number of bits used for the beam information reported for each time instance are equal. For example, if K i =1, meaning that only the strongest beam is reported for each time instance.
[0260] As an example, each Top-Ki beam information includes K i Beam information. The K... i Each beam information in the beam information indicates a beam in Set A.
[0261] The first node determines the multiple second-type beam information on the N second-type time instances according to the measurement result of the first resource set, which is introduced above in combination with FIG. 5 to FIG. 7. The multiple second-type beam information indicated by the first information is the information of part of the beams in all the beams corresponding to the N second-type time instances. When the first node transmits the N second-type time instances and the multiple second-type beam information through the first information, the reporting of the prediction result can be performed through less resource overhead.
[0262] In some embodiments, the first information can indicate the N second-type time instances and the multiple beam information in multiple ways. Exemplarily, the inference result of the UE-side AI / ML model can report the N second-type time instances and the corresponding Top-K i beams in multiple ways. Exemplary descriptions are made below in combination with multiple embodiments.

The resource indication of the N second-type time instances is a time slot index of the N second-type time instances, and / or, the N second-type time instances are indexed in a prediction window. For example, when a prediction window is configured, time instance i can be the index of the corresponding time slot in all time slots included in the prediction window.

[0285] Embodiment 2
[0286] To save signaling overhead, a plurality of resource sets can be configured through high-layer signaling. The plurality of resource sets can respectively indicate a plurality of time instance sets. For example, one of the plurality of resource sets can indicate N second-type time instances. In this scenario, the first information no longer needs to indicate the N second-type time instances, but indicates through the resource set.

[0294] In some embodiments, the first information can comprise an identification of the second resource set to determine the N second-type time instances. Exemplarily, the identification of the second resource set can be used by the second node to determine the N second-type time instances. As an example, the first information can comprise an identification of the second resource set to which the N second-type time instances correspond. The identification of the second resource set can be referred to as a second resource set ID, indicating the second resource set to which the N second-type time instances correspond.
[0295] As an example, the first information can comprise a set of N beam information and an identification of the second resource set. The identification of the second resource set indicates the N second-type time instances. It can be seen that the N second-type time instances belong to any of the plurality of resource sets.
[0296] In some embodiments, the plurality of resource sets in which the second resource set is located can be indicated by a second resource set list, so as to facilitate the first node to indicate the second resource set based on the second resource list, and facilitate the second node to determine the N second-type time instances according to the first information.
[0297] As an example, the second resource set list comprises a plurality of resource sets, and the second resource set is one of the resource sets in the second resource set list.
[0298] As an example, the identification of the second resource set is used to determine the second resource set from the second resource set list.

[0311] As an example, the K jthe K beams in the L beams on the jth second-type time instance of the N second-type time instances have a signal quality greater than a first threshold value j beams.
[0312] As an embodiment, the L beams on the ith second-type time instance are the same as the L beams on the jth second-type time instance, or are not the same.
[0313] For ease of understanding, the method in which the first information includes the second resource set identifier is exemplarily introduced below in combination with FIG. 10.
[0314] Referring to FIG. 10, the first information also includes two types of fields arranged side by side. The first type of field indicates a resource set ID. The resource set ID is an identifier of a second resource set. The second type of field indicates N beam information sets corresponding to N second-type time instances in sequence, respectively, beam information set 1 to beam information set N. The content in each beam information set is the same as that in FIG. 8, and is not described again.
[0315] The above introduces the reporting method in which the first information includes N second-type time instances and a second resource set identifier in combination with FIG. 10. Compared with embodiment 1, this embodiment saves a part of signaling overhead.
[0316] Embodiment 3
[0317] Since the geographical position and surrounding environment of the terminal device do not change much within a prediction window / period / phase, many beam information in the N beam information sets may be the same. That is, many beam information in the N groups of Top-K i beam information corresponding to the N second-type time instances are the same. In this scenario, embodiments 1 and 2 may cause redundant signaling overhead to indicate duplication.
[0318] Considering that the predicted beam lasts for a period of time and the predicted beam is limited within a certain prediction period, the present application proposes a reporting method in which the first information is mainly beam information.
[0319] In some embodiments, the first information can include K T beam information and a set of K T time instances. Exemplarily, the K T beam information can belong to the second-type beam information, or can be the second-type beam information.

[0331] As an embodiment, the N second-type time instances correspond to N groups of beams. The N groups of beams include N x K i beams. The second-type beam information includes beam information of K T beams. The K T beams are all different beams in the N x K i strongest beams, or the K T beams are K i strongest beams in the N x K T strongest beams.
[0332] In some embodiments, the K T beam information indicates L beams in the N second-type time instances or K i different beams in the N x K T strongest beams in the i-th second-type time instance. That is, the K T beams can be the L beams, or can be all different beams in N groups of Top-K i beams predicted in the N time instances. In this scenario, the value of K T is fixed, and the signaling overhead of the first information is unchanged.
[0333] As an embodiment, the first information includes information of the L beams corresponding to the K T beam information.
[0334] As an embodiment, the K T beams are determined according to signal qualities of all beams in the N x K i strongest beams in the N second-type time instances. Therefore, the K TEach beam can also be called Top-K. T One beam.

Specifically, FIG. 17 shows a block diagram of a first communication device 1750 and a second communication device 1710 which communicate with each other in an access network.
[0429] The first communication device 1750 includes a controller / processor 1759, a memory 1760, a data source 1767, a transmission processor 1768, a reception processor 1756, a multi-antenna transmission processor 1757, a multi-antenna reception processor 1758, a transmitter / receiver 1754 and an antenna 1752.
[0430] The second communication device 1710 includes a controller / processor 1775, a memory 1776, a data source 1777, a receive processor 1770, a transmit processor 1716, a multi-antenna receive processor 1772, a multi-antenna transmit processor 1771, a transmitter / receiver 1718, and antennas 1720.
[0431] In the transmission from the second communication device 1710 to the first communication device 1750, at the second communication device 1710, upper layer packets from a core network or upper layer packets from the data source 1777 are provided to the controller / processor 1775. The core network and the data source 1777 represent all protocol layers above the L2 layer. The controller / processor 1775 implements the functionality of the L2 layer. In the transmission from the second communication device 1710 to the first communication device 1750, the controller / processor 1775 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for the first communication device 1750 based on various priority metrics. The controller / processor 1775 is also responsible for retransmission of lost packets, and signaling to the first communication device 1750. The transmit processor 1716 and the multi-antenna transmit processor 1771 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 1716 implements coding and interleaving to facilitate forward error correction at the second communication device 1710, and mapping of data packets onto signal constellations based on various modulation schemes (e.g., binary phase-shift keying, quadrature phase-shift keying, M-phase-shift keying, M-quadrature amplitude modulation). The multi-antenna transmit processor 1771 performs digital spatial precoding of the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. The transmit processor 1716 then maps to each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time and / or frequency domain, and then performs an inverse fast Fourier transform to produce a time-domain multicarrier symbol stream for the physical channel. The multi-antenna transmit processor 1771 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 1718 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 1771 into a radio frequency stream, and then provides the radio frequency stream to the different antennas 1720.
[0432] In the transmission from the second communication device 1710 to the first communication device 1750, at the first communication device 1750, each receiver 1754 receives a signal through its respective antenna 1752. Each receiver 1754 recovers information modulated onto an RF carrier and converts the RF stream into a baseband multicarrier symbol stream, which provides to the receive processor 1756. The receive processor 1756 and the multi-antenna receive processor 1758 implement various signal processing functions of the LI layer. The multi-antenna receive processor 1758 performs receive analog precoding / beamforming operation on the baseband multicarrier symbol stream from the receivers 1754. The receive processor 1756 converts the baseband multicarrier symbol stream from the receive analog precoding / beamforming operation from the time domain to the frequency domain using a fast Fourier transform. In the frequency domain, the physical layer data signals and the reference signals are demultiplexed by the receive processor 1756, where the reference signals will be used for channel estimation, and the data signals are recovered after multi-antenna detection in the multi-antenna receive processor 1758 for any spatial streams destined for the first communication device 1750. The symbols on each spatial stream are demodulated and recovered by the receive processor 1756 and generate soft decisions. The receive processor 1756 then decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 1710 on the physical channels. The upper layer data and control signals are then provided to the controller / processor 1759. The controller / processor 1759 implements the functions of the L2 layer. The controller / processor 1759 can be associated with a memory 1760 that stores program codes and data. The memory 1760 can be referred to as a computer readable medium.

The data source 1767 represents all protocol layers above L2. Similar to the transmit function at the second communication device 1710 described in the transmission from the second communication device 1710 to the first communication device 1750, the controller / processor 1759 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels, L2 layer functionality for the user plane and control plane. The controller / processor 1759 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 1710. A transmit processor 1768, which can be implemented as part of a controller / processor 1759, generates modulation symbols for the data packet from the data source 1767, control symbols for each user terminal from the controller / processor 1759, and pilot symbols for each antenna from the controller / processor 1759. A transmit (TX) multiple-input multiple-output (MIMO) processor 1757 performs digital precoding on the modulation symbols, pilot symbols, and control symbols, if applicable, and provides output symbol streams from the transmit processor 1768 to the various antenna 1752 via separate transmitters 1754. Each transmitter 1754 modulates (or conditions) a respective output symbol stream from the transmit MIMO processor 1757, converts to analog, and amplifies it to generate a modulated signal suitable for transmission over the MIMO channel. Further, the modulated signals from the transmitters 1754 are transmitted via the antennas 1752 to the second communication device 1710.
[0434] In the transmission from the first communication device 1750 to the second communication device 1710, the functionality at the second communication device 1710 is similar to the receive functionality described at the first communication device 1750 in the transmission from the second communication device 1710 to the first communication device 1750. Each receiver 1718 receives a signal from its respective antenna 1720, converts the received signal to a baseband signal, and provides the baseband signal to the transmit (TX) multiple-input multiple-output (MIMO) processor 1772 and the receive processor 1770. The receive processor 1770 and the TX MIMO processor 1772 implement the functionality of the Ll layer. A controller / processor 1775 implements the functionality of the L2 layer. The controller / processor 1775 can be associated with a memory 1776, which stores program codes and data. The memory 1776 can be referred to as a computer-readable medium. In the transmission from the first communication device 1750 to the second communication device 1710, the controller / processor 1775 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the first communication device 1750. Upper layer packets from the controller / processor 1775 can be provided to the core network or all the protocol layers above L2.
